Associations between smoking and pain in early recovery in residential substance use treatment-seekers.

INTRODUCTION: A growing literature indicates bidirectional associations between pain and tobacco use. Cigarette smokers are at increased risk for chronic pain, and observational and experimental studies indicate that pain increases motivation to smoke. Tobacco use disorder frequently co-occurs with other substance use disorders, which are also associated with chronic pain vulnerability. Despite evidence that pain significantly predicts smoking and relapse, associations between smoking history/trajectory and changes in pain over the course of treatment have not been characterized. The objective of the study was to determine the association between in-treatment smoking trajectory, pack-years (i.e., number of cigarette packs smoked per day multiplied by smoking duration), pain-related interference in daily activities, and pain intensity over the course of residential treatment. METHODS: In this study, 280 adult smokers in a residential SUD treatment center in North Central Florida completed questionnaires assessing cigarette use, pain intensity, and pain interference at treatment entry and discharge (Mean = 80.3 days, SD = 25.6). Most participants were diagnosed with alcohol use disorder (66.1 %). Opioid (27.9 %) and cannabis use disorders (29.6 %) were also common. Participants were grouped by whether their smoking increased (n = 36), decreased (n = 46), or stayed the same (n = 133) from entry to discharge. RESULTS: Analyses indicated a positive association between pack-years and pain intensity at both baseline (r = 0.185, p = 0.018) and discharge (r = 0.184, p = 0.019). Smoking trajectory was associated with pack-years, with those decreasing smoking having greater pack-years than those sustaining or increasing use [F(2,136) = 8.62, p < 0.01, η2p = 0.114]. Mixed general linear models indicated pain intensity [F(1,274) = 44.15, p < 0.0001, η2p = 0.138] and interference in day-to-day activities [F(1,276) = 31.79, p < 0.0001, η2p = 0.103] decreased significantly over time. However, there was no main effect of smoking trajectory on pain intensity [F(2,212) = 2.051, p = 0.131, η2p = 0.019] or of smoking trajectory by time interaction [F(2, 212) = 1.228, p = 0.295, η2p = 0.011]. CONCLUSIONS: Overall, findings provide evidence that smoking behavior influences pain within the context of residential substance use treatment. Given that pain is associated with urge to use substances and risk of return to use, more consistent and rigorous assessment of pain and proactive pain management is likely to enhance substance use treatment outcomes among people who smoke.

The effect of vitamin D and omega-3 fatty acid supplementation on pain prevalence and severity in older adults: a large-scale ancillary study of the VITamin D and OmegA-3 triaL (VITAL).

ABSTRACT: A diet supplemented with vitamin D and marine omega-3 fatty acids may prevent and treat painful disorders by promoting the resolution of inflammation. However, large, randomized placebo-controlled trials evaluating the effects of supplementation with omega-3 fatty acids and vitamin D on the presence and severity of pain are lacking. VITamin D and OmegA-3 triaL-Pain (VITAL-Pain) is an ancillary study to the VITAL trial, a large randomized, double-blind, placebo-controlled trial of vitamin D (2000 IU/day) and omega-3 supplementation (1 g/day) over 5.3 years of median follow-up, among 25,871 older men and women. We assessed pain among those reaching the end of the VITAL intervention phase using questions from the 2012 National Health Interview Survey. We used ordinal logistic regression to test the effect of vitamin D and omega-3 fatty acids on the odds ratio (OR) and 95% confidence interval [CI] of reporting higher pain prevalence or severity. Overall, 19,611 participants provided complete pain information at the end of the VITAL trial. The ORs for higher pain prevalence or severity for vitamin D and omega-3 supplementation vs placebo were 0.99 ([CI] 0.94-1.05) and 0.99 ([CI] 0.94-1.04), respectively. There was no interaction between the 2 active treatments. Dietary supplementation with commonly used moderate doses of vitamin D or omega-3 fatty acids over a median of 5.3 years did not result in a lower prevalence or severity of pain in middle-aged and older U.S. adults.

Psychosocial well-being and quality of life in women with breast cancer in foothills of North India.

Introduction: Breast cancer remains a leading cause of unintended death among Indian women. Cancer treatment-induced pain, fatigue, nausea/vomiting, body image, and sexual problems could affect the patient psychosocial well-being and quality of life (QOL). The study aims to determine the QOL and psychosocial well-being among women with breast cancer. Materials and Methods: A cross-sectional survey completed by 244 women with breast cancer at a tertiary level teaching hospital. The European Organisation for Research and Treatment of Cancer QOL Questionnaire C30, the Breast Module (QLQ-BR23), and the Hospital Anxiety and Depression Scale (HADS) is used to measure the QOL, and psychological well-being, respectively. Appropriate descriptive and inferential statistics are applied to compute the results. Results: The total number of women with breast cancer interviewed was 244, with a mean age of 45.06 (standard deviation ± 11.17) years. The mean global health score was 70.97 ± 15.63. As per the QLQ-C30 scale, "physical functioning" scored the highest (70.54 ± 22.00), and "role functioning" reported the lowest (49.45 ± 36.15) mean score. Further, on the QLQ-C30 symptoms scale, "appetite loss" (45.09 ± 35.09) was the worst reported symptom, followed by "nausea and vomiting" (34.97 ± 38.39). On the BR-23 scale, body image said (68.42 ± 22.28) higher score than other domains and experience of arm-related problems (43.80 ± 26.06) were more frequently reported symptom in women. As per the HADS scale, 24.6% and 36.1% of women were in moderate anxiety and depression, respectively. The mean HADS score was 14.39 ± 5.82. Findings on predictors for the individual patient remained the same as that earlier published literature. Conclusions and Recommendations: Women with breast cancer have an overall good QOL and poor psychosocial well-being. However, using a holistic approach, including identifying psychological problems and their time management, signifies the need for the studied population.

A Cross-Sectional and Longitudinal Study of Pain among Middle-Aged and Older Adults in Thailand.

Objective: The present study aimed to assess the prevalence and risk factors of pain among ageing adults in Thailand. Methods: Cross-sectional and longitudinal data were analysed from two consecutive national waves of the Health, Aging, and Retirement in Thailand (HART) study in 2015 and 2017. The dependent variable pain was defined as moderate or severe pain in any of the 13 areas of the body over the past month. Independent variables included sociodemographic factors, health risk behaviour, physical and mental health conditions, and healthcare utilization. Results: The baseline or cross-sectional sample consisted of 5,616 participants (≥45 years), and the follow-up or incident sample consisted of 2,305 participants. The proportion of pain in the cross-sectional/baseline sample was 36.0%, and in the incident/follow-up sample 39.9%. In the cross-sectional/baseline multivariable model, poor self-reported mental health, sleep problem, arthritis or rheumatism, brain disease and/or psychiatric problems, lung disease, use of hospital in-patient, conventional out-patient, and traditional medicine practitioners were positively associated with pain. In the incident/follow-up multivariable model, older age, Buddhist religion, class I obesity, poor self-reported mental health, hospital in-patient, private clinic out-patient, and use of a practitioner of traditional medicine were positively associated with pain. Male sex and higher education were negatively associated with both cross-sectional and incident pain. Conclusions: More than one-third of older adults in Thailand had past month moderate or severe pain. Risk factors of pain from cross-sectional and/or incident analysis included older age, female sex, lower education, obesity, poor self-reported mental health, sleep problem, arthritis or rheumatism, brain disease and/or psychiatric problems, lung disease, and conventional and traditional healthcare utilization.

Do Adolescent Idiopathic Scoliosis Patients With Vitamin D Deficiency Have Worse Spine Fusion Outcomes?

BACKGROUND: Prior research has shown that patients with adolescent idiopathic scoliosis (AIS) have a higher prevalence of vitamin D deficiency compared with healthy peers. In adult orthopaedic populations, vitamin D deficiency has been shown to be a risk factor for higher reported pain and lower function. We investigated whether there was an association between vitamin D levels and AIS patient-reported outcomes, as measured by the Scoliosis Research Society (SRS-30) questionnaire. METHODS: This was a single-center, cross-sectional study. Postoperative AIS patients were prospectively recruited during routine follow-up visits, 2 to 10 years after spine fusion. Vitamin D levels were measured by serum 25-hydroxyvitamin D (ng/mL). Patients were categorized based on vitamin D level: deficient (<20 ng/mL), insufficient (20 to 29 ng/mL), or sufficient (≥30 ng/mL). The correlation between vitamin D levels and SRS-30 scores was analyzed using multivariable analysis and pair-wise comparisons using Tukey method. RESULTS: Eighty-seven AIS patients (83% female) were enrolled who presented at median 3 years (interquartile range: 2 to 5 y; range: 2 to 10 y) after spine fusion. Age at time of surgery was mean 15 (SD±2) years. Major coronal curves were a mean of 57 (SD±8) degrees preoperatively and 18 (SD±7) degrees postoperatively. It was found that 30 (34%) of patients were vitamin D sufficient, 33 (38%) were insufficient, and 24 (28%) were deficient. Although there was no correlation between vitamin D level and Pain, Mental Health, or Satisfaction domains ( P >0.05), vitamin D-deficient patients were found to be younger ( P <0.001) and had lower SRS-30 function ( P =0.002), Self-image ( P <0.001), and total scores ( P =0.003). CONCLUSIONS: AIS patients with vitamin D deficiency (<20 ng/mL) are more likely to be younger age at time of surgery, and report lower Function, Self-image, and Total SRS-30 scores postoperatively. Further work is needed to determine whether vitamin D supplementation alters curve progression and patient outcomes. LEVEL OF EVIDENCE: Level II-prognostic study.

Evaluation of work ability index and its association with job stress and musculoskeletal disorders among midwives during the Covid-19 pandemic.

BACKGROUND: Musculoskeletal disorders (MSDs) and work-related stress are among the factors that can negatively affect work ability. Given the importance of midwives' health, this study aims to evaluate the work ability of midwives and to investigate its association with the prevalence of MSDs and work-related stress in midwifery. METHODS: Ninety-one midwives participated in this study. Three questionnaires, including Nordic musculoskeletal questionnaire (NMQ) plus body map, Persian version of work ability index (WAI) questionnaire, and Health and Safety Executive (HSE) job stress questionnaire, were used to collect data. Finally, the association of MSDs, work-related stress, and individual characteristics with WAI among midwives was investigated. RESULTS: The highest rates of pain and discomfort were reported in the lower back and neck. The mean job stress was 116.08 with the highest scores on demand, role, and control subscales. The work ability among midwives was at an acceptable level of 39.07 on average. Inter-variable association analysis showed that the work ability was significantly associated with pain in the past 12 months and the number of coexisting MSDs. Job stress was not associated with work ability. CONCLUSIONS: Midwives' WAI was at an acceptable level despite high prevalence of MSDs in midwives, the confirmation of the possible correlation between MSDs and work ability, as well as the high job stress in midwifery. Since the present study was conducted during the Covid-19 pandemic, the high stress in midwives may be partly due to the pandemic and may not be permanent. However, this level of stress may reduce the midwives' work ability over a long time.

Comparison of short-stem versus conventional stem for hip arthroplasty in patients younger than 60 years: 7-14 years follow-up.

PURPOSE: Short-stem prostheses in hip arthroplasty have emerged as an alternative to conventional stems, especially in younger patients. The purpose of this study was to compare functional and radiological results of a short metaphyseal fitting cementless stem versus a conventional stem implant, in patients younger than 60 years. METHODS: All patients operated from January 2006 to April 2013 were included, obtaining a minimum follow-up of 7 years. Harris Hip Score (HHS) and SF-36 (quality of life) questionnaires were applied and the presence of "thigh pain" was specifically assessed. We also compared complication rate, revision rate and average prosthesis survival. Femoral stress shielding (Gruen scale), stem subsidence, varus-valgus tilt and implant stability (Engh scale) were also compared. RESULTS: A total of 101 short-stem and 74 conventional arthroplasties were included, with an average follow-up of 9.82 (7-14) years. HHS functional score and SF-36 were excellent in both implants and no significant difference between them (p > 0.05) was found. However, "thigh pain" was present in 7 patients with conventional stems and none with short-stems (p < 0.001). The survival rate at 13 years was 99%, for both implants, and no significant differences were found between them (χ2(2) = 0.178; p = 0.673). Conventional stems had stress shielding at the greater trochanter in 72% of the cases and 43% at the calcar, being statistically superior (p < 0.001) to the stress shielding observed in the short stems. CONCLUSION: According to our results, this short-stem seems to allow preservation of bone stock, with decreased stress shielding and also a lower incidence of thigh pain compared to conventional stems. LEVEL OF EVIDENCE: Level III retrospective comparative study.

Ethnotherapeutic Uses and Phytochemical Composition of Physalis peruviana L.: An Overview.

BACKGROUND: Plant-derived medicines are widespread and continue to increase in traditional and modern medicine, especially in developing countries. Physalis peruviana L. is among the most used plants in conventional medication worldwide. This review aimed to highlight the ethnotherapeutic uses and phytochemical status of identified compounds in P. peruviana. METHODS: Data were collected from Google Scholar, PubMed/Medline, SciFinder, Science Direct, Scopus, the Wiley Online Library, Web of Science, and any other helpful search engine using Physalis peruviana as the primary keyword. RESULTS: Some countries, worldwide, use P. peruviana in their traditional medicine system to manage diverse ailments, mainly diseases and gastrointestinal tract disorders (25.33%). Leaf was the mostly used part (49.28%), prepared by decoction (31.58%) and overall administrated orally (53.57%) as the main route of admission. Around 502 phytoconstituents were identified in different plant parts, especially fruit (38.19%) ethanol/ethyl acetate extract. In most cases (36.17%), the solvent of the extract was not specified. Several phytochemical classes were found in the plant, especially terpenes (26.09%) and phenolic compounds (14.94%). Esters were also abundant (11.55%). In the terpenes category, carotenoids were the most abundant (11.15% followed by monoterpenes (8.76%) and diterpenes (3.18%). However, flavonoids (5.17%) followed by cinnamic acid derivatives (3.99%), monophenolic compounds (1.79%), and phenolic acids (1.33 M) are the most reported phenolic compounds. Hexadecanoic acid (palmitic acid) was the most cited (five times). CONCLUSION: P. peruviana plays an essential role in managing diseases in some countries and is rich in chemical compounds, which need to be isolated and investigated pharmacologically before clinical trials.

Efficacy of hypertonic dextrose injection (prolotherapy) in temporomandibular joint dysfunction: a systematic review and meta-analysis.

Hypertonic dextrose prolotherapy (DPT) has been reported to be effective for temporomandibular disorders (TMDs) in clinical trials but its overall efficacy is uncertain. To conduct a systematic review with meta-analysis of randomized controlled trials (RCTs) to synthesize evidence on the effectiveness of DPT for TMDs. Eleven electronic databases were searched from their inception to October, 2020. The primary outcome of interest was pain intensity. Secondary outcomes included maximum inter-incisal mouth opening (MIO) and disability score. Studies were graded by "Cochrane risk of bias 2" tool; if data could be pooled, a meta-analysis was performed. Ten RCTs (n = 336) with some to high risk of bias were included. In a meta-analysis of 5 RCTs, DPT was significantly superior to placebo injections in reducing TMJ pain at 12 weeks, with moderate effect size and low heterogeneity (Standardized Mean Difference: - 0.76; 95% CI - 1.19 to - 0.32, I2 = 0%). No statistically significant differences were detected for changes in MIO and functional scores. In this systematic review and meta-analysis, evidence from low to moderate quality studies show that DPT conferred a large positive effect which met criteria for clinical relevance in the treatment of TMJ pain, compared with placebo injections.Protocol registration at PROSPERO: CRD42020214305.

Factors influencing clinical symptoms and treatment of patients with traffic accident injuries: A retrospective chart review with a questionnaire survey.

This study analyzed factors influencing clinical symptoms and treatment of patients with traffic accident injuries. It used a retrospective chart review and questionnaire survey obtained from 560 patients (266 men and 294 women). It also conducted follow-up observations of progress after car insurance settlements and investigated the usefulness of and patient satisfaction with integrative Korean medicine treatment for traffic accident injuries. Retrospective data of patients admitted for traffic accident injury were obtained. A questionnaire survey was conducted to collect data regarding the degree of traffic accident damage, severity of pain at settlement, any treatment after settlement and duration and cost of such treatment, and patient satisfaction with car insurance services and Korean medicine treatment for traffic accident injury. The results showed no significant association between pain and the degree of damage to the car at the time of traffic accident (P = 0.662), although the degree of damage to the car was more significantly associated with time to reach a car insurance settlement than severity of pain in the patient (P = 0.003). There was no significant association between the degree of damage to the car in a traffic accident and pain after a traffic accident. Greater severity of pain at the time of the car insurance settlement was associated with greater cost and longer time spent in treatment after the car insurance settlement.

Prevalence and Factors Associated With Body Pain: Results of a Nationally Representative Survey of 9,586 Chinese Adults Aged 60 and Over.

Background: Pain management has become a critical problem worldwide with the aging population. More than half of older people have experienced pain with different severity. The aim of this research is to identify the characteristics of older people with body pain and the associations between pain and characteristics of demographic, health status, and health services use amongst Chinese seniors. Methods: This cross-sectional study was based on the China Health and Retirement Longitudinal Study (CHARLS), using follow-up survey data in 2015. The national survey comprised 20,284 women and men aged 45 years or older who completed questionnaires. Data of older people who were asked whether they had troubles with body pain were extracted and analyzed. Multiple logistic regression modeling was used to determine the important indicators (demographic, health status, and health services use) amongst Chinese elderly with pain. Results: Analyses revealed that 32.5% (n = 9,586) of Chinese people aged over 60 reported having body pain. Pain is positively associated with female gender (OR = 2.08, 95% CI 1.80-2.39, p < 0.001), living in non-urban areas (OR = 1.49, 95% CI 1.25-1.77, p < 0.001), having physical disabilities (OR = 1.45, 95% CI 1.15-1.82, p = 0.002), diagnosed with stomach diseases (OR = 1.40, 95% CI 1.20-1.64, p < 0.001), diagnosed with arthritis (OR = 1.91, 95% CI 1.66-2.20, p < 0.001), self-rating with poor health status (OR = 7.03, 95% CI 5.63-8.78, p < 0.001), self-purchased over-the-counter western medications (OR = 1.50, 95% CI 1.30-1.73, p < 0.001) and self-purchased Chinese herbal medicine (OR = 1.52, 95% CI 1.24-1.85, p < 0.001). Conclusion: Body pain is common amongst the Chinese elderly. This research highlights the need for further nationwide studies exclusively focusing on people with pain including the elder population, and provides evidence-based insights for healthcare providers and policy-makers, to improve the quality of pain management. Future research should also pay attention to the importance of health literacy for health outcomes with regard to pain management.

Significant Pain Reduction in Hospitalized Patients Receiving Integrative Medicine Interventions by Clinical Population and Accounting for Pain Medication.

Background: Prior research has reported that integrative medicine (IM) therapies reduce pain in inpatients, but without controlling for important variables. Here, the authors extend prior research by assessing pain reduction while accounting for each patient's pain medication status and clinical population. Methods: The initial data set consisted of 7,106 inpatient admissions, aged ≥18 years, between July 16, 2012, and December 15, 2014. Patients' electronic health records were used to obtain data on demographic, clinical measures, and pain medication status during IM. Results: The final data set included first IM therapies delivered during 3,635 admissions. Unadjusted average pre-IM pain was 5.33 (95% confidence interval [CI]: 5.26 to 5.41) and post-IM pain was 3.31 (95% CI: 3.23 to 3.40) on a 0-10 scale. Pain change adjusted for severity of illness, clinical population, sex, treatment, and pain medication status during IM was significant and clinically meaningful with an average reduction of -1.97 points (95% CI: -2.06 to -1.86) following IM. Adjusted average pain was reduced in all clinical populations, with largest and smallest pain reductions in maternity care (-2.34 points [95% CI: -2.56 to -2.14]) and orthopedic (-1.71 points [95% CI: -1.98 to -1.44]) populations. Pain medication status did not have a statistically significant association on pain change. Decreases were observed regardless of whether patients were taking narcotic medications and/or nonsteroidal anti-inflammatory drugs versus no pain medications. Conclusions: For the first time, inpatients receiving IM reported significant and clinically meaningful pain reductions during a first IM session while accounting for pain medications and across clinical populations. Future implementation research should be conducted to optimize identification/referral/delivery of IM therapies within hospitals. Clinical Trials.gov #NCT02190240.

Opioid-sparing effects of cannabinoids: Myth or reality?

A converging line of evidence is indicating that cannabinoids may have an opioid-sparing effect. This property, well validated in preclinical studies, allow when both drugs are co-administered to reduce the dose of opioids without loss of analgesic effects. A meta-analysis of pre-clinical studies indicated in 2017 that the median effective dose (ED50) of morphine administered in combination with delta-9-tetrahydrocannabinol (delta-9-THC) is 3.6 times lower than the ED50 of morphine alone (Nielsen et al., 2017). However, very few studies have been conducted in humans to validate this effect. This narrative review provides an update on whether or not cannabinoid drugs can be used to produce an opioid sparing effect. For this, various lines of evidence ranging from preclinical, epidemiological and human studies will be summarized. Overall, this review indicates that the preclinical results are strongly and consistently supportive of the presence of an opioid sparing effect of cannabinoid drugs. However, to date the clinical studies have been mostly negative; and, the evidence collected in humans so far is so limited that it is premature to conclude. Therefore, prospective high quality controlled clinical trials are still required to validate this. Priorities for future research are also discussed.

Do Thoracic Spinal Deformities Affect Outcomes of Spinal Cord Stimulators: A Retrospective Chart Review.

STUDY DESIGN: Retrospective chart review. OBJECTIVE: The aim of this study was to ascertain whether the presence of structural thoracic deformities affects outcomes of permanent SCS placement. SUMMARY OF BACKGROUND DATA: Neural modulation via spinal cord stimulators (SCSs) has become an accepted treatment option for various chronic pain syndromes. In most cases, the surgeon desires accurate midline positioning of the paddle lead, allowing for flexibility of unilateral or bilateral coverage of pain patterns. Structural spinal deformities (scoliosis or kyphosis) often result from coronal, sagittal, and rotatory deformity that can make midline placement more difficult. METHODS: Between 2013 and 2017, two-hundred forty-one charts of patients who underwent permanent SCS placement at our suburban hospital were reviewed. Demographic information, numerical rating system (NRS) pain scores, Oswestry Disability Index (ODI) scores, and opioid medication usage were recorded at baseline and after permanent stimulator placement. Thoracic scoliosis and kyphosis angles were measured using spinal radiographs. The effect of each structural deformity on NRS, ODI, and narcotic medication usage changes from baseline was analyzed. RESULTS: Overall, 100 patients were included in our cohort. Fifty-six patients had measured thoracic spinal deformities (38% with scoliosis, 31% with kyphosis). There was no significant difference in NRS scores, ODI scores, or narcotic usage change between patients with scoliosis and those without (P = 0.66, P = 0.57, P = 0.75) or patients with kyphosis and those without (P = 0.51, P = 0.31, P = 0.63). Bivariate linear regression analysis showed that scoliotic and kyphotic angles were not significant predictors of NRS (P = 0.39, P = 0.13), ODI (P = 0.45, P = 0.07), and opioid usage (P = 0.70, P = 0.90) change, with multivariate regression analyses confirming these findings. CONCLUSION: SCSs can be effective options for treating lumbar back pain and radiculopathy. Our study suggests that the presence of mild structural deformities does not adversely affect outcomes of permanent SCS placement and as such should not preclude this population from benefiting from such therapies.Level of Evidence: 4.

Redefining Pain and Addiction: Creation of a Statewide Curriculum.

OBJECTIVES: In response to a declared statewide public health emergency due to opioid-related overdose deaths, the Arizona Department of Health Services guided the creation of a modern, statewide, evidence-based curriculum on pain and addiction that would be relevant for all health care provider types. METHODS: The Arizona Department of Health Services convened and facilitated 4 meetings during 4 months with a workgroup comprising the deans and curriculum representatives of all 18 medical, osteopathic, physician assistant, nurse practitioner, dental, podiatry, and naturopathic programs in Arizona. During this collaborative and iterative process, the workgroup reviewed existing curricula, established a philosophical framework, and developed a flexible and practical structure for a curriculum that would suit the needs of all program types. RESULTS: The Arizona Pain and Addiction Curriculum was finalized in June 2018. The curriculum aims to redefine pain and addiction as multidimensional public health issues and is structured as 10 core components, each supported by a detailed set of evidence-based objectives. The curriculum includes a set of annual metrics to collect from both programs (focused on implementation progress and barriers) and learners (focused on knowledge, attitudes, and practice plans). CONCLUSIONS: To our knowledge, this is the first example of a statewide collaboration among diverse health professional education programs to create a single, standard curriculum. This collaborative process and the nonproprietary Arizona Pain and Addiction Curriculum may serve as a useful template for other states to enhance pain and addiction education.

Adductor longus injury after electromechanical self-treatment: A case report.

OBJECTIVE: This case report illustrates an unusual cause of hip adductor muscle injury due to overenthusiastic self-treatment of the previously overloaded adductor muscles. Also, post-injury therapeutic objectives and intervention to facilitate rapid participation in sports after the described process are provided. CASE DESCRIPTION: A 27-year old male, professional soccer player presented with hip adductors pain and impairment due to electromechanical self-treatment of the affected area. He was evaluated using hip-strength assessments, self-report, ultrasonography (US), and magnetic resonance imaging (MRI) until complete functional recovery had occurred. Along with clinical presentation, diagnostic imaging showed evidence of an isolated injury to the adductor longus muscle. A well-structured rehabilitation and readaptation program was followed in order to ensure early recovery and optimal functional outcome. OUTCOMES: The athlete was able to participate in a full soccer training session without any limitation 18 days after his self-treatment session. The patient returned to his previous level of performance by 3rd week post-injury. CONCLUSION: To the authors' knowledge, this is the first report of muscle strain due to overenthusiasthic therapy. Although this is a rare complication of self-treatment procedures, patients and therapists should be aware of this risk in order to prevent and rapidly identify the lesion.

The Role of Pain Catastrophizing and Depression in the Outcomes of Physical Therapy in a Prospective Osteoarthritis Cohort.

BACKGROUND: Physical modalities have been safely used for decades for pain relief and for reducing physical disability in the conservative treatment of knee osteoarthritis (OA). However, patients' response to treatment is highly variable, which may be related to certain patient-related factors such as pain catastrophizing and depression. OBJECTIVES: This study aimed to evaluate the effects of pain catastrophizing and depression on physical therapy outcomes and to identify the baseline factors predictive of poor outcomes in patients with knee OA. STUDY DESIGN: This research used a prospective, cohort, observational study design. SETTING: The research took place in an outpatient physical therapy unit within a tertiary hospital in Ankara, Turkey. METHODS: Eighty-nine patients with knee OA underwent 10 sessions of physical therapy. At baseline, depression and pain catastrophizing were evaluated using the Beck Depression Inventory-II (BDI-II) and the Pain Catastrophizing Scale (PCS). The therapeutic efficacy of physical therapy was assessed based on the level of pain and disability using the Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Changes in the VAS score and WOMAC were evaluated at 2 and 6 weeks following physical therapy. A multivariate logistic regression analysis was conducted to identify the predictors of poor outcomes. RESULTS: Patients with low pain-catastrophizing and low depression scores tended to demonstrate better improvement at weeks 2 and 6. The results of a multivariate logistic regression analysis showed that the significant outcome predictor for both pain and function at week 6 was the baseline PCS score. The baseline depression score was not an independent predictor of a clinically poor outcome. LIMITATIONS: This study is limited owing to the combined use of several physical therapy modalities and short follow-up. CONCLUSIONS: This study suggests that the baseline PCS score is a predictive factor of poor response to physical therapy in patients with knee OA. Considering this factor before therapy and taking the necessary precautions may improve the outcomes of physical therapy. KEY WORDS: Catastrophization, central nervous system sensitization, depression, disability evaluation, knee osteoarthritis, pain, physical therapy modalities, transcutaneous electric nerve stimulation.

Kratom (Mitragyna speciosa): User demographics, use patterns, and implications for the opioid epidemic.

BACKGROUND: Kratom, a Southeast Asian plant with opioid-receptor mediated effects, has emerged as a potential substance of abuse, with limited data on its use and effects. This study characterized kratom user demographics, use patterns, and perceived drug effects. METHODS: A cross-sectional, anonymous online survey was conducted between January and December 2017. RESULTS: 2,798 kratom users - mean age 40 (SD = 12); predominantly White (90 %), female (61 %), and located in the US (97 %) - completed the survey. Kratom was primarily taken orally in doses of 1-3 g (49 %), with daily use (59 %) being most common. Kratom was used for pain (91 %), anxiety (67 %), and depression (65 %), with high ratings of effectiveness. 1,144 (41 %) used kratom to stop or reduce prescription or illicit opioid use, citing decreased opioid withdrawal and craving related to kratom use, with 411 reporting >1-year continuous abstinence from opioids attributed to kratom use. Roughly one-third of respondents reported adverse effects of kratom, largely rated as mild in severity and lasting ≤24 h. Seventeen participants (0.6 %) sought treatment for adverse effects. Fifty-six individuals (2 %) met DSM-5 criteria for a past-year moderate or severe kratom-related substance use disorder (SUD). When asked how troubled they felt regarding their kratom use, the mean (SD) rating was 3.2 (9.8) on a scale from 0 to 100. CONCLUSION: Kratom is used among White, middle-aged Americans for symptoms of pain, anxiety, depression, and opioid withdrawal. Although regular use was typical, kratom-related SUD and serious adverse effects were uncommon. Additional research on kratom epidemiology and pharmacology is imperative in light of the present opioid epidemic.

The analgesic efficacy and safety of peri-articular injection versus intra-articular injection in one-stage bilateral total knee arthroplasty: a randomized controlled trial.

BACKGROUND: As an essential component of multimodal analgesia approaches after total knee arthroplasty (TKA), local infiltration analgesia (LIA) can be classified into peri-articular injection (PAI) and intra-articular injection (IAI) according to administration techniques. Currently, there is no definite answer to the optimal choice between the two techniques. Our study aims to investigate analgesic efficacy and safety of PAI versus IAI in patients receiving simultaneous bilateral TKA. METHODS: This randomized controlled trial was conducted from February 2017 and finished in July 2018. Sixty patients eligible for simultaneous bilateral total knee arthroplasty were randomly assigned to receive PAI on one side and IAI on another. Primary outcomes included numerical rating scale (NRS) pain score at rest or during activity at 3 h, 6 h, 12 h, 24 h, 48 h, and 72 h following surgery. Secondary outcomes contained active or passive range of motion (ROM) at 1, 2, and 3 days after surgery, time to perform straight leg raise, wound drainage, operation time, and wound complications. RESULTS: Patients experienced lower NRS pain scores of the knee receiving PAI compared with that with PAI during the first 48 h after surgery. The largest difference of NRS pain score at rest occurred at 48 h (PAI: 0.68, 95%CI[0.37, 0.98]; IAI: 2.63, 95%CI [2.16, 3.09]; P < 0.001); and the largest difference of NRS pain score during activity also took place at 48 h (PAI: 2.46, 95%CI [2.07, 2.85]; IAI: 3.90, 95%CI [3.27, 4.52]; P = 0.001). PAI group had better results of range of motion and time to perform straight leg raise when compared with IAI group. There were no differences in operation time, wound drainage, and wound complication. CONCLUSION: PAI had the superior performance of pain relief and improvement of range of motion to IAI. Therefore, the administration technique of peri-articular injection is recommended when performing local infiltration analgesia after total knee arthroplasty. TRIAL REGISTRATION: The trial was retrospectively registered in the Chinese Clinical Trial Registry as ChiCTR1800020420 on 29th December, 2018. LEVEL OF EVIDENCE: Therapeutic Level I.
