Developing an initial set of quality indicators for chiropractic care: a scoping review.

BACKGROUND: Quality indicators are standardized, evidence-based measures of health care quality. Currently, there is no basic set of quality indicators for chiropractic care published in peer-reviewed literature. The goal of this research is to develop a preliminary set of quality indicators, measurable with administrative data. METHODS: We conducted a scoping review searching PubMed/MEDLINE, CINAHL, and Index to Chiropractic Literature databases. Eligible articles were published after 2011, in English, developing/reporting best practices and clinical guidelines specifically developed for, or directly applicable to, chiropractic care. Eligible non-peer-reviewed sources such as quality measures published by the Centers for Medicare and Medicaid Services and the Royal College of Chiropractors quality standards were also included. Following a stepwise eligibility determination process, data abstraction identified specific statements from included sources that can conceivably be measured with administrative data. Once identified, statements were transformed into potential indicators by: 1) Generating a brief title and description; 2) Documenting a source; 3) Developing a metric; and 4) Assigning a Donabedian category (structure, process, outcome). Draft indicators then traversed a 5-step assessment: 1) Describes a narrowly defined structure, process, or outcome; 2) Quantitative data can conceivably be available; 3) Performance is achievable; 4) Metric is relevant; 5) Data are obtainable within reasonable time limits. Indicators meeting all criteria were included in the final set. RESULTS: Literature searching revealed 2562 articles. After removing duplicates and conducting eligibility determination, 18 remained. Most were clinical guidelines (n = 10) and best practice recommendations (n = 6), with 1 consensus and 1 clinical standards development study. Data abstraction and transformation produced 204 draft quality indicators. Of those, 57 did not meet 1 or more assessment criteria. After removing duplicates, 70 distinct indicators remained. Most indicators matched the Donabedian category of process (n = 35), with 31 structure and 4 outcome indicators. No sources were identified to support indicator development from patient perspectives. CONCLUSIONS: This article proposes a preliminary set of 70 quality indicators for chiropractic care, theoretically measurable with administrative data and largely obtained from electronic health records. Future research should assess feasibility, achieve stakeholder consensus, develop additional indicators including those considering patient perspectives, and study relationships with clinical outcomes.

A scoping review to identify barriers and facilitators of research participation among chiropractic faculty.

OBJECTIVE: To describe peer-reviewed literature on chiropractic faculty participation in research and identify important barriers and facilitators. METHODS: We conducted a scoping review using comprehensive searches of relevant databases from inception through November 2022. English language publications of any design were included, with search terms consisting of subject headings specific to each database and free text words related to chiropractic, faculty, and research. Primary and secondary reviewer teams performed article screening and data abstraction using Covidence software, with primary reviewers responsible for consensus. Data were entered into evidence tables and analyzed descriptively. RESULTS: A total of 330 articles were screened, with 14 deemed eligible including 8 cross-sectional/correlational studies and 6 narrative reviews/editorials. Article publication dates ranged from 1987 to 2017. No intervention studies were identified. Facilitators of chiropractic faculty research included research assignment as primary role, institutional culture promoting research, and dedicated release time. Barriers included teaching/clinic assignments, lack of incentives and mentorship, and teaching load. Qualitative results identified 5 domains impacting faculty research: demographics/professional roles; personal empowerment; research culture; institutional setting/policies; and research training. CONCLUSION: Our scoping review found a paucity of recently published articles on chiropractic faculty participation in research. Educational institutions building research capacity among chiropractic faculty must establish cultural environments where scholarship is expected, rewarded, and valued. Tangible support, such as research policies, resources, and space, advanced training, funding, and release time, must be available. Faculty are encouraged to build upon key facilitators, evaluate interventions to address barriers to chiropractic faculty research, and publish their results.

Predictors of Pain Management Strategies in Adults with Low-Back Pain: A Secondary Analysis of Amazon Mechanical Turk Survey Data.

Objective: To evaluate the associations between baseline demographics, health conditions, pain management strategies, and health-related quality-of-life (HRQoL) measures with pain management strategies at 3-month follow-up in respondents reporting current low-back pain (LBP). Study design: Cohort study of survey data collected from adults with LBP sampled from Amazon Mechanical Turk crowdsourcing panel. Methods: Demographics, health conditions, and the Patient-Reported Outcomes Measurement Information System (PROMIS)-10 were included in the baseline survey. Respondents reporting LBP completed a more comprehensive survey inquiring about pain management strategies and several HRQoL measures. Bivariate then multivariate logistic regression estimated odds ratios (ORs) with 95% confidence intervals (CIs) for the association between baseline characteristics and pain management utilization at 3-month follow-up. Model fit statistics were evaluated to assess the predictive value. Results: The final cohort included 717 respondents with completed surveys. The most prevalent pain management strategy at follow-up was other care (n = 474), followed by no care (n = 94), conservative care only (n = 76), medical care only (n = 51), and medical and conservative care combined (n = 22). The conservative care only group had higher (better) mental and physical health PROMIS-10 scores as opposed to the medical care only and combination care groups, which had lower (worse) physical health scores. In multivariate models, estimated ORs (95% CIs) for the association between baseline and follow-up pain management ranged from 4.6 (2.7-7.8) for conservative care only to 16.8 (6.9-40.7) for medical care only. Additional significant baseline predictors included age, income, education, workman's compensation claim, Oswestry Disability Index score, and Global Chronic Pain Scale grade. Conclusions: This study provides important information regarding the association between patient characteristics, HRQoL measures, and LBP-related pain management utilization.

Psychedelic Research and Therapeutic Practices: Embracing Communities, Groups, and Traditional Knowledge.

The global prevalence of substance abuse and mental disorders continues to challenge healthcare systems, with one in eight individuals affected. The therapeutic potential of psychedelics is recognized not only for treating mental disorders but also for enhancing well-being and promoting pro-social behaviors. Conventional biomedical research models fall short in addressing the broader health needs of populations and poorly suited for overcoming barriers to service delivery. This special issue includes six articles that explore alternative approaches to psychedelic research and practice, emphasizing collaboration with diverse actors, including indigenous communities, and incorporating traditional knowledge systems into contemporary psychedelic research. They underscore the need for innovative research methods that engage multidisciplinary approaches while promoting culturally relevant outcome measures. They emphasize the importance of shifting from punitive drug policies to those grounded in public health and human rights, allowing for multi-country studies and the development of evidence-based care models for community mental health. Incorporating traditional knowledge and community-based methodologies into psychedelic science is vital for its evolution beyond biomedical research for widespread dissemination, offering new avenues for improved health outcomes and promotion of human flourishing.

Psychedelic Science, Contemplative Practices, and Indigenous and Other Traditional Knowledge Systems: Towards Integrative Community-Based Approaches in Global Health.

As individuals and communities around the world confront mounting physical, psychological, and social threats, three complimentary mind-body-spirit pathways toward health, wellbeing, and human flourishing remain underappreciated within conventional practice among the biomedical, public health, and policy communities. This paper reviews literature on psychedelic science, contemplative practices, and Indigenous and other traditional knowledge systems to make the case that combining them in integrative models of care delivered through community-based approaches backed by strong and accountable health systems could prove transformative for global health. Both contemplative practices and certain psychedelic substances reliably induce self-transcendent experiences that can generate positive effects on health, well-being, and prosocial behavior, and combining them appears to have synergistic effects. Traditional knowledge systems can be rich sources of ethnobotanical expertise and repertoires of time-tested practices. A decolonized agenda for psychedelic research and practice involves engaging with the stewards of such traditional knowledges in collaborative ways to codevelop evidence-based models of integrative care accessible to the members of these very same communities. Going forward, health systems could consider Indigenous and other traditional healers or spiritual guides as stakeholders in the design, implementation, and evaluation of community-based approaches for safely scaling up access to effective psychedelic treatments.

A comparison of mental imagery and perceptual cueing across domains of attention.

Mental imagery and perceptual cues can influence subsequent visual search performance, but examination of this influence has been limited to low-level features like colors and shapes. The present study investigated how the two types of cues influence low-level visual search, visual search with realistic objects, and executive attention. On each trial, participants were either presented with a colored square or tasked with using mental imagery to generate a colored square that could match the target (valid trial) or distractor (invalid trial) in the search array that followed (Experiments 1 and 3). In a separate experiment, the colored square displayed or generated was replaced with a realistic object in a specific category that could appear as a target or distractor in the search array (Experiment 2). Although the displayed object was in the same category as an item in the search display, they were never a perfect match (e.g., jam drop cookie instead of chocolate chip). Our findings revealed that the facilitation of performance on valid trials compared with invalid trials was greater for perceptual cues than imagery cues for low-level features (Experiment 1), whereas the influence of these two types of cues was comparable in the context of realistic objects (Experiment 2) The influence of mental imagery appears not to extend to the resolution of conflict generated by color-word Stroop stimuli (Experiment 3). The present findings extend our understanding of how mental imagery influences the allocation of attention.

Efficacy and safety of a novel source of dietary 25-hydroxycholecalciferol in growing pigs.

A randomized complete block design experiment was conducted to determine the safety and efficacy of supplementation of increasing concentrations of a novel, bacterial fermentation-derived vitamin D source on growth performance and tissue deposition of 25-hydroxycholecalciferol (25OHD3) in growing swine. Dietary treatments were as follows: commercial control with vitamin D3 (CON) at NRC recommended concentrations and three diets composed of CON + increasing inclusions (25, 50, and 250 µg/kg equivalent) of 25OHD3 from a novel source (CON + 25; CON + 50; and CON + 250, respectively). Pigs (n = 144) were assigned to 24 pens which were allotted to one of the four dietary treatments and fed for 42 d. Blood samples were collected for 25OHD3 concentration determination and individual body weights (BW) were measured on experimental day 0, 39, and 63. On day 42, tissues from 48 pigs (12 pigs per dietary treatment) were analyzed for 25OHD3 concentration. No differences were observed in growth performance. Day 39 serum 25OHD3 concentrations were greatest in CON + 250-fed pigs and linearly decreased as dietary 25OHD3 inclusion decreased (P < 0.0001). On day 42, tissue 25OHD3 concentrations increased linearly as 25OHD3 increased in the diet (P < 0.0001). On day 63, 21 d after dietary 25OHD3 withdrawal, serum 25OHD3 concentrations of all 25OHD3-fed pigs decreased to that of or within 2.76 ±â€…0.89 ng/mL of CON-fed pigs which demonstrates that feeding 250 µg/kg 25OHD3 is well tolerated by growing pigs and will clear the body within 21 d.

Pigs require several essential nutrients to meet their needs for maintenance, growth, reproduction, and other functions. It is important to provide these nutrients to the animals properly to assure their health and wellbeing as well as the profitability of production. Vitamin D is a nutrient that plays an important role in bone development and mineralization since it regulates calcium and phosphorus metabolism. Vitamin D has also been reported to aid in additional functions including immunity. Vitamin D can be synthetized in plants and is also produced in humans and animals when ultraviolet rays from sunlight strike the skin and lead to vitamin D synthesis. In pigs, vitamin D requirements can also be satisfied by dietary sources. The objective of this experiment was to determine the efficacy and safety of supplementation of a novel, bacterial fermentation-derived vitamin D source on growth and tissue accumulation in growing swine. Based on the results obtained, it can be concluded that concentrations of vitamin D in serum and tissue samples increased as dietary vitamin D supplementation increased, but did not alter growth performance, nor did there appear to be any safety issues with feeding up to 250 µg per kg feed of this vitamin D source to growing pigs.

Guideline-concordant utilization of magnetic resonance imaging in adults receiving chiropractic manipulative therapy vs other care for radicular low back pain: a retrospective cohort study.

BACKGROUND: Lumbar magnetic resonance imaging (LMRI) is often performed early in the course of care, which can be discordant with guidelines for non-serious low back pain. Our primary hypothesis was that adults receiving chiropractic spinal manipulative therapy (CSMT) for incident radicular low back pain (rLBP) would have reduced odds of early LMRI over 6-weeks' follow-up compared to those receiving other care (a range of medical care, excluding CSMT). As a secondary hypothesis, CSMT recipients were also expected to have reduced odds of LMRI over 6-months' and 1-years' follow-up. METHODS: A national 84-million-patient health records database including large academic healthcare organizations (TriNetX) was queried for adults age 20-70 with rLBP newly-diagnosed between January 31, 2012 and January 31, 2022. Receipt or non-receipt of CSMT determined cohort allocation. Patients with prior lumbar imaging and serious pathology within 90 days of diagnosis were excluded. Propensity score matching controlled for variables associated with LMRI utilization (e.g., demographics). Odds ratios (ORs) of LMRI over 6-weeks', 6-months', and 1-years' follow-up after rLBP diagnosis were calculated. RESULTS: After matching, there were 12,353 patients per cohort (mean age 50 years, 56% female), with a small but statistically significant reduction in odds of early LMRI in the CSMT compared to other care cohort over 6-weeks' follow-up (9%, 10%, OR [95% CI] 0.88 [0.81-0.96] P = 0.0046). There was a small but statistically significant increase in odds of LMRI among patients in the CSMT relative to the other care cohort over 6-months' (12%, 11%, OR [95% CI] 1.10 [1.02-1.19], P < 0.0174) and 1-years' follow-up (14%, 12%, OR [95% CI] 1.21 [1.13-1.31], P < 0.0001). CONCLUSIONS: These results suggest that patients receiving CSMT for newly-diagnosed rLBP are less likely to receive early LMRI than patients receiving other care. However, CSMT recipients have a small increase in odds of LMRI over the long-term. Both cohorts in this study had a relatively low rate of early LMRI, possibly because the data were derived from academic healthcare organizations. The relationship of these findings to other patient care outcomes and cost should be explored in a future randomized controlled trial. REGISTRATION: Open Science Framework ( https://osf.io/t9myp ).

If the Doors of Perception Were Cleansed, Would Chronic Pain be Relieved? Evaluating the Benefits and Risks of Psychedelics.

Psychedelic substances have played important roles in diverse cultures, and ingesting various plant preparations to evoke altered states of consciousness has been described throughout recorded history. Accounts of the subjective effects of psychedelics typically focus on spiritual and mystical-type experiences, including feelings of unity, sacredness, and transcendence. Over the past 2 decades, there has been increasing interest in psychedelics as treatments for various medical disorders, including chronic pain. Although concerns about adverse medical and psychological effects contributed to their controlled status, contemporary knowledge of psychedelics suggests that risks are relatively rare when patients are carefully screened, prepared, and supervised. Clinical trial results have provided support for the effectiveness of psychedelics in different psychiatric conditions. However, there are only a small number of generally uncontrolled studies of psychedelics in patients with chronic pain (eg, cancer pain, phantom limb pain, migraine, and cluster headache). Challenges in evaluating psychedelics as treatments for chronic pain include identifying neurobiologic and psychosocial mechanisms of action and determining which pain conditions to investigate. Truly informative proof-of-concept and confirmatory randomized clinical trials will require careful selection of control groups, efforts to minimize bias from unblinding, and attention to the roles of patient mental set and treatment setting. PERSPECTIVE: There is considerable promise for the use of psychedelic therapy for pain, but evidence-based recommendations for the design of future studies are needed to ensure that the results of this research are truly informative.

Risk of Treatment Escalation in Recipients vs Nonrecipients of Spinal Manipulation for Musculoskeletal Cervical Spine Disorders: An Analysis of Insurance Claims.

OBJECTIVE: The purpose of this study was to evaluate the relationship between treatment escalation and spinal manipulation in a retrospective cohort of people diagnosed with musculoskeletal disorders of the cervical spine. METHODS: We used retrospective analysis of insurance claims data (2012-2018) from a single Fortune 500 company. After isolating the first episode of care, we categorized 58 147 claims into 7951 unique patient episodes. Treatment escalation included claims where imaging, injection, emergency room, or surgery was present. Modified Poisson regression was used to determine the relative risk of treatment escalation comparing recipients vs nonrecipients of spinal manipulation, adjusted for age, sex, episode duration, and risk scores. RESULTS: The sample was 55% women, with a mean age of 44 years (range, 18-103). Treatment escalation was present in 42% of episodes overall: 2448 (46%) associated with other care and 876 (26%) associated with spinal manipulation. The estimated risk of any treatment escalation was 2.38 times higher in those who received other care than in those who received spinal manipulation (95% confidence interval, 2.22-2.55, P = .001). CONCLUSION: Among episodes of care associated with neck pain diagnoses, those associated with other care had twice the risk of any treatment escalation compared with those associated with spinal manipulation. In the United States, over 90% of spinal manipulation is provided by doctors of chiropractic; therefore, these findings are relevant and should be considered in addressing solutions for neck pain. Additional research investigating the factors influencing treatment escalation is necessary to moderate the use of high-cost and guideline-incongruent procedures in people with neck pain.

The Effect of Reduced Access to Chiropractic Care on Medical Service Use for Spine Conditions Among Older Adults.

OBJECTIVE: The purpose of this study was to examine the extent to which access to chiropractic care affects medical service use among older adults with spine conditions. METHODS: We used Medicare claims data to identify a cohort of 39,278 older adult chiropractic care users who relocated during 2010-2014 and thus experienced a change in geographic access to chiropractic care. National Plan and Provider Enumeration System data were used to determine chiropractor per population ratios across the United States. A reduction in access to chiropractic care was defined as decreasing 1 quintile or more in chiropractor per population ratio after relocation. Using a difference-in-difference analysis (before versus after relocation), we compared the use of medical services among those who experienced a reduction in access to chiropractic care versus those who did not. RESULTS: Among those who experienced a reduction in access to chiropractic care (versus those who did not), we observed an increase in the rate of visits to primary care physicians for spine conditions (an annual increase of 32.3 visits, 95% CI: 1.4-63.1 per 1,000) and rate of spine surgeries (an annual increase of 5.5 surgeries, 95% CI: 1.3-9.8 per 1,000). Considering the mean cost of a visit to a primary care physician and spine surgery, a reduction in access to chiropractic care was associated with an additional cost of $114,967 per 1,000 beneficiaries on medical services ($391 million nationally). CONCLUSIONS: Among older adults, reduced access to chiropractic care is associated with an increase in the use of some medical services for spine conditions.

Three Patterns of Spinal Manipulative Therapy for Back Pain and Their Association With Imaging Studies, Injection Procedures, and Surgery: A Cohort Study of Insurance Claims.

OBJECTIVE: The purpose of this study was to evaluate the relationship between procedures and care patterns in back pain episodes by analyzing health insurance claims. METHODS: We performed a retrospective cohort study of insurance claims data from a single Fortune 500 company. The 3 care patterns we analyzed were initial spinal manipulative therapy, delayed spinal manipulative therapy, and no spinal manipulative therapy. The 3 procedures analyzed were imaging studies, injection procedures, and back surgery. We considered "escalated care" to be any claims with diagnostic imaging, injection procedures, or back surgery. Modified-Poisson regression modeling was used to determine relative risk of escalated care. RESULTS: There were 83 025 claims that were categorized into 10 372 unique patient first episodes. Spinal manipulative therapy was present in 2943 episodes (28%). Initial spinal manipulation was present in 2519 episodes (24%), delayed spinal manipulation was present in 424 episodes (4%), and 7429 (72%) had no evidence of spinal manipulative therapy. The estimated relative risk, adjusted for age, sex, and risk score, for care escalation (eg, imaging, injections, or surgery) was 0.70 (95% confidence interval 0.65-0.75, P < .001) for initial spinal manipulation and 1.22 (95% confidence interval 1.10-1.35, P < .001) for delayed spinal manipulation with no spinal manipulation used as the reference group. CONCLUSION: For claims associated with initial episodes of back pain, initial spinal manipulative therapy was associated with an approximately 30% decrease in the risk of imaging studies, injection procedures, or back surgery compared with no spinal manipulative therapy. The risk of imaging studies, injection procedures, or back surgery in episodes in the delayed spinal manipulative therapy group was higher than those without spinal manipulative therapy.

Acetaminophen, ibuprofen, and tramadol analgesic interactions after adenotonsillectomy.

BACKGROUND: The impact of tramadol in children given acetaminophen-ibuprofen combination therapy is uncertain in acute pediatric pain management. A model describing the interaction between these three drugs would be useful to understand the role of supplemental analgesic therapy. METHODS: Children undergoing tonsillectomy were given oral paracetamol and ibuprofen perioperatively. Blood was taken for paracetamol and ibuprofen drug assay on up to six occasions over 6 h after the initial dose. Tramadol was administered by caregivers for unacceptable postoperative pain. Pain was measured using the Parent's Postoperative Pain Measurement rating two hourly on the first postoperative day. A first-order absorption, one-compartment linear model with first-order elimination was used to describe acetaminophen and ibuprofen disposition. Analgesia was described using an EMAX model extended for three drugs, assuming additive effects. Curve fitting was performed using nonlinear mixed effects models. RESULTS: Pharmacodynamic parameter estimates, expressed using fractional Hill equation, were maximum effect (EMAX ) 0.65 (95%CI 0.54, 0.74), the concentration of acetaminophen associated with 50% of the maximal drug effect (C50,ACET ) 7.06 (95%CI 7.03, 7.72) mg/L, and the ibuprofen C50 (C50,IBU ) 3.95 (95%CI 2.57, 7.53) mg/L. The Hill coefficient was 1.48 (95%CI 0.92, 2.62) and an interaction term was fixed at zero (additivity). The half-time (t1/2 keo) for equilibration between the plasma and effect site was 0.34 hour (95%CI 0.23, 1.98) for acetaminophen and 1.04 hour (95%CI 0.75, 1.77) for ibuprofen. Tramadol had a C50,TRAM of 0.07 (95%CI 0.048, 1.07) mg/L with a t1/2 keo,TRAM 1.78 hour (95%CI 1.06, 1.96). CONCLUSION: Ibuprofen has an EC50 for analgesia in children similar to that of adults (3.95 mg/L; 95%CI 2.57-7.53, vs 5-10 mg/L adults). The maximum effect from combination therapy (ie, 65% reduction in pain score) achieves satisfactory analgesia with commonly used doses but increased dose adds little additional benefit. The addition of tramadol to this analgesic mixture prolongs analgesia duration.

Treatment of a Patient With Central Pain Sensitization Using Graded Motor Imagery Principles: A Case Report.

OBJECTIVE: This case report describes the application of graded motor imagery principles to a patient experiencing central sensitization and chronic pain. CLINICAL FEATURES: A 46-year-old woman presented with pain in all 4 limbs along with global spinal pain and loss of range of motion. These symptoms initiated after a motor vehicle accident 5 years before and were exacerbated by 2 subsequent motor vehicle accidents. Examination indicated global loss of spinal range of motion, severe apprehension toward any movement, decreased grip strength bilaterally, and loss of 2-point discrimination. A variety of outcome assessments indicated severe disability. INTERVENTION AND OUTCOME: The patient was seen at the chiropractic clinic 5× over 6 weeks and showed marked improvement with each visit. Treatment included pain neuroscience education, laterality training using the Recognize app, and explicit motor imagery. The patient demonstrated improvement in all baseline measures just described, including outcome assessment scores. CONCLUSIONS: Over time, the patient reported decreased chronic pain and disability, along with improvement in grip strength and range of motion, after application of graded motor imagery strategies.

Non-steroidal anti-inflammatory drugs (NSAIDs) for chronic non-cancer pain in children and adolescents.

BACKGROUND: Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. While in the past pain was largely dismissed and was frequently left untreated, views on children's pain have changed over time, and relief of pain is now seen as important.We designed a suite of seven reviews on chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol) in order to review the evidence for children's pain utilising pharmacological interventions.As the leading cause of morbidity in the world today, chronic disease (and its associated pain) is a major health concern. Chronic pain (that is pain lasting three months or longer) can arise in the paediatric population in a variety of pathophysiological classifications (nociceptive, neuropathic, or idiopathic) from genetic conditions, nerve damage pain, chronic musculoskeletal pain, and chronic abdominal pain, as well as for other unknown reasons.Non-steroidal anti-inflammatory drugs (NSAIDs) are used to treat pain, reduce fever, and for their anti-inflammation properties. They are commonly used within paediatric pain management. Non-steroidal anti-inflammatory drugs are currently licensed for use in Western countries, however they are not approved for infants under three months old. The main adverse effects include renal impairment and gastrointestinal issues. Common side effects in children include diarrhoea, headache, nausea, constipation, rash, dizziness, and abdominal pain. OBJECTIVES: To assess the analgesic efficacy and adverse events of NSAIDs used to treat chronic non-cancer pain in children and adolescents aged between birth and 17 years, in any setting. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online, MEDLINE via Ovid, and Embase via Ovid from inception to 6 September 2016. We also searched the reference lists of retrieved studies and reviews, as well as online clinical trial registries. SELECTION CRITERIA: Randomised controlled trials, with or without blinding, of any dose and any route, treating chronic non-cancer pain in children and adolescents, comparing any NSAID with placebo or an active comparator. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for eligibility. We planned to use dichotomous data to calculate risk ratio and number needed to treat for one additional event, using standard methods. We assessed GRADE and created three 'Summary of findings' tables. MAIN RESULTS: We included seven studies with a total of 1074 participants (aged 2 to 18 years) with chronic juvenile polyarthritis or chronic juvenile rheumatoid arthritis. All seven studies compared an NSAID with an active comparator. None of the studies were placebo controlled. No two studies investigated the same type of NSAID compared with another. We were unable to perform a meta-analysis.Risk of bias varied. For randomisation and allocation concealment, one study was low risk and six studies were unclear risk. For blinding of participants and personnel, three studies were low risk and four studies were unclear to high risk. For blinding of outcome assessors, all studies were unclear risk. For attrition, four studies were low risk and three studies were unclear risk. For selective reporting, four studies were low risk, two studies were unclear risk, and one study was high risk. For size, three studies were unclear risk and four studies were high risk. For other potential sources of bias, seven studies were low risk. Primary outcomesThree studies reported participant-reported pain relief of 30% or greater, showing no statistically significant difference in pain scores between meloxicam and naproxen, celecoxib and naproxen, or rofecoxib and naproxen (P > 0.05) (low-quality evidence).One study reported participant-reported pain relief of 50% or greater, showing no statistically significant difference in pain scores between low-dose meloxicam (0.125 mg/kg) and high-dose meloxicam (0.25 mg/kg) when compared to naproxen 10 mg/kg (P > 0.05) (low-quality evidence).One study reported Patient Global Impression of Change, showing 'very much improved' in 85% of ibuprofen and 90% of aspirin participants (low-quality evidence). Secondary outcomesAll seven studies reported adverse events. Participants reporting an adverse event (one or more per person) by drug were: aspirin 85/202; fenoprofen 28/49; ibuprofen 40/45; indomethacin 9/30; ketoprofen 9/30; meloxicam 18/47; naproxen 44/202; and rofecoxib 47/209 (very low-quality evidence).All seven studies reported withdrawals due to adverse events. Participants withdrawn due to an adverse event by drug were: aspirin 16/120; celecoxib 10/159; fenoprofen 0/49; ibuprofen 0/45; indomethacin 0/30; ketoprofen 0/30; meloxicam 10/147; naproxen 17/285; and rofecoxib 3/209 (very low-quality evidence).All seven studies reported serious adverse events. Participants experiencing a serious adverse event by drug were: aspirin 13/120; celecoxib 5/159; fenoprofen 0/79; ketoprofen 0/30; ibuprofen 4/45; indomethacin 0/30; meloxicam 11/147; naproxen 10/285; and rofecoxib 0/209 (very low-quality evidence).There were few or no data for our remaining secondary outcomes: Carer Global Impression of Change; requirement for rescue analgesia; sleep duration and quality; acceptability of treatment; physical functioning as defined by validated scales; and quality of life as defined by validated scales (very low-quality evidence).We rated the overall quality of the evidence (GRADE rating) for our primary and secondary outcomes as very low because there were limited data from studies and no opportunity for a meta-analysis. AUTHORS' CONCLUSIONS: We identified only a small number of studies, with insufficient data for analysis.As we could undertake no meta-analysis, we are unable to comment about efficacy or harm from the use of NSAIDs to treat chronic non-cancer pain in children and adolescents. Similarly, we cannot comment on our remaining secondary outcomes: Carer Global Impression of Change; requirement for rescue analgesia; sleep duration and quality; acceptability of treatment; physical functioning; and quality of life.We know from adult randomised controlled trials that some NSAIDs, such as ibuprofen, naproxen, and aspirin, can be effective in certain chronic pain conditions.

Vegetated Treatment Systems for Removing Contaminants Associated with Surface Water Toxicity in Agriculture and Urban Runoff.

Urban stormwater and agriculture irrigation runoff contain a complex mixture of contaminants that are often toxic to adjacent receiving waters. Runoff may be treated with simple systems designed to promote sorption of contaminants to vegetation and soils and promote infiltration. Two example systems are described: a bioswale treatment system for urban stormwater treatment, and a vegetated drainage ditch for treating agriculture irrigation runoff. Both have similar attributes that reduce contaminant loading in runoff: vegetation that results in sorption of the contaminants to the soil and plant surfaces, and water infiltration. These systems may also include the integration of granulated activated carbon as a polishing step to remove residual contaminants. Implementation of these systems in agriculture and urban watersheds requires system monitoring to verify treatment efficacy. This includes chemical monitoring for specific contaminants responsible for toxicity. The current paper emphasizes monitoring of current use pesticides since these are responsible for surface water toxicity to aquatic invertebrates.

Oral delivery of [D-Leu-4]-OB3 and MA-[D-Leu-4]-OB3, synthetic peptide leptin mimetics: Immunofluorescent localization in the mouse hypothalamus.

This study describes the localization of [D-Leu-4]-OB3 and MA-[D-Leu-4]-OB3, synthetic peptide leptin mimetics, in the hypothalamus of Swiss Webster and C57BL/6J wild-type mice, leptin-deficient ob/ob mice, and leptin-resistant diet-induced obese (DIO) mice. The mice were given [D-Leu-4]-OB3 or MA-[D-Leu-4]-OB3 in 0.3% dodecyl maltoside by oral gavage. Once peak serum concentrations were reached, the mice received a lethal dose of pentobarbital and were subjected to intracardiac perfusion fixation. The brains were excised, post-fixed in paraformaldehyde, and cryo-protected in sucrose. Free-floating frozen coronal sections were cut at 25-µm and processed for imaging by immunofluorescence microscopy. In all four strains of mice, dense staining was concentrated in the area of the median eminence, at the base and/or along the inner wall of the third ventricle, and in the brain parenchyma at the level of the arcuate nucleus. These results indicate that [D-Leu-4]-OB3 and MA-[D-Leu-4]-OB3 cross the blood-brain barrier and concentrate in an area of the hypothalamus known to regulate energy balance and glucose homeostasis. Most noteworthy is the localization of [D-Leu-4]-OB3 immunoreactivity within the hypothalamus of DIO mice via a conduit that is closed to leptin in this rodent model, and in most cases of human obesity. Together with our previous studies describing the effects of [D-Leu-4]-OB3 and MA-[D-Leu-4]-OB3 on energy balance, glucose regulation, and signal transduction pathway activation, these findings are consistent with a central mechanism of action for these synthetic peptide leptin mimetics, and suggest their potential usefulness in the management of leptin-resistant obesity and type 2 diabetes in humans.

Previously Undiagnosed Malignant Brain Tumor Discovered During Examination of a Patient Seeking Chiropractic Care.

OBJECTIVE: This case report describes the diagnosis of a malignant brain tumor in a patient requesting chiropractic care for headaches after a motor vehicle accident. CLINICAL FEATURES: A 30-year-old man presented with numbness and tingling in all extremities, lower extremity muscle weakness, and a recent increase in headaches with the loss of ability to concentrate. He was involved in a high-speed motor vehicle collision approximately 4 months before the onset of symptoms. Examination showed slow gait with a lack of arm swing, bilateral hip flexors and knee extensors were all graded as 4/5 on muscle testing, and cranial nerve examination was unremarkable with the exception of 2 beats of nystagmus on left lateral eye movement. Because of these findings and a family history of multiple sclerosis, the patient was referred for a brain magnetic resonance imaging scan. INTERVENTION AND OUTCOME: Imaging showed a craniocervical junction mass centered at the floor of the fourth ventricle with obstruction of foramina and marked impingement on the medulla. A posterior fossa craniotomy and tumor removal procedure was performed by a neurosurgeon, followed by 34 sessions of radiation therapy. The final diagnosis was a grade II glioma with features of ependymoma. CONCLUSIONS: This report describes the clinical presentation, examination, and medical management of a 30-year-old man presenting to a chiropractic practice with an unsuspected malignant brain tumor.

Multi-regional investigation of the relationship between functional MRI blood oxygenation level dependent (BOLD) activation and GABA concentration.

Several recent studies have reported an inter-individual correlation between regional GABA concentration, as measured by MRS, and the amplitude of the functional blood oxygenation level dependent (BOLD) response in the same region. In this study, we set out to investigate whether this coupling generalizes across cortex. In 18 healthy participants, we performed edited MRS measurements of GABA and BOLD-fMRI experiments using regionally related activation paradigms. Regions and tasks were the: occipital cortex with a visual grating stimulus; auditory cortex with a white noise stimulus; sensorimotor cortex with a finger-tapping task; frontal eye field with a saccade task; and dorsolateral prefrontal cortex with a working memory task. In contrast to the prior literature, no correlation between GABA concentration and BOLD activation was detected in any region. The origin of this discrepancy is not clear. Subtle differences in study design or insufficient power may cause differing results; these and other potential reasons for the discrepant results are discussed. This negative result, although it should be interpreted with caution, has a larger sample size than prior positive results, and suggests that the relationship between GABA and the BOLD response may be more complex than previously thought.
