RESUMO
Electronic Nicotine Delivery Systems (ENDS) aerosol exposures can induce endothelial dysfunction (ED) in healthy young humans and animals. Thermal degradation of ENDS solvents, propylene glycol and vegetable glycerin (PG: VG), generates abundant formaldehyde (FA) and other carbonyls. Because FA can activate the transient receptor potential ankyrin-1 (TRPA1) sensor, we hypothesized that FA in ENDS aerosols provokes TRPA1-mediated changes that include ED and 'respiratory braking' - biomarkers of harm. To test this, wild-type (WT) and TRPA1-null mice were exposed by inhalation to either filtered air, PG: VG-derived aerosol, or formaldehyde (FA, 5 ppm). Short-term exposures to PG: VG and FA induced ED in female WT but not in female TRPA1-null mice. Moreover, acute exposures to PG: VG and FA stimulated respiratory braking in WT but not in TRPA1-null female mice. Urinary metabolites of FA (ie, N -1,3-thiazolidine-4-carboxylic acid, TCA; N -1,3-thiazolidine-4-carbonyl glycine, TCG) and monoamines were measured by LC-MS/MS. PG: VG and FA exposures significantly increased urinary excretion of both TCA and TCG in both WT and TRPA1-null mice. To confirm that inhaled FA directly contributed to urinary TCA, mice were exposed to isotopic 13C-FA gas (1 ppm, 6 h).13C-FA exposure significantly increased the urine level of 13C-TCA in the early collection (0-3 h) supporting a direct relationship between inhaled FA and TCA. Collectively, these data suggest that ENDS use may increase CVD risk dependent on FA, TRPA1, and catecholamines, yet independently of either nicotine or flavorants. This study supports that levels of FA in ENDS-derived aerosols should be lowered to mitigate CVD risk in people who use ENDS.
RESUMO
OBJECTIVE: Juvenile fibromyalgia (JFM) is a complex chronic pain condition that remains poorly understood. The study aimed to expand the clinical characterization of JFM in a large representative sample of adolescents with JFM and identify psychological factors that predict pain interference. METHODS: Participants were 203 adolescents (ages 12-17 years) who completed baseline assessments for the multisite Fibromyalgia Integrative Training for Teens (FIT Teens) randomized control trial. Participants completed the Pain and Symptom Assessment Tool, which includes a Widespread Pain Index (WPI; 0-18 pain locations) and Symptom Severity checklist of associated somatic symptoms (SS; 0-12) based on the 2010 American College of Rheumatology criteria for fibromyalgia. Participants also completed self-report measures of pain intensity, functional impairment, and psychological functioning. RESULTS: Participants endorsed a median of 11 painful body sites (WPI score) and had a median SS score of 9. Fatigue and nonrestorative sleep were prominent features and rated as moderate to severe by 85% of participants. Additionally, neurologic, autonomic, gastroenterologic, and psychological symptoms were frequently endorsed. The WPI score was significantly correlated with pain intensity and catastrophizing, while SS scores were associated with pain intensity and all domains of physical and psychological functioning. Depressive symptoms, fatigue, and pain catastrophizing predicted severity of pain impairment. CONCLUSION: JFM is characterized by chronic widespread pain with fatigue, nonrestorative sleep, and other somatic symptoms. However, how diffusely pain is distributed appears less important to clinical outcomes and impairment than other somatic and psychological factors, highlighting the need for a broader approach to the assessment and treatment of JFM.

Objective: To describe protocol adaptations to the Fibromyalgia Integrative Training for Teens (FIT Teens) randomized controlled trial in response to the COVID-19 pandemic. The overarching aims of the FIT Teens multi-site 3-arm comparative effectiveness trial are to assess whether a specialized neuromuscular exercise training intervention combined with cognitive-behavioral therapy (CBT) is superior to CBT alone or graded aerobic exercise alone. Design/methods: The trial was originally designed as an in-person, group-based treatment with assessments at baseline, mid- and post-treatment, and four follow-up time points. The original study design and methodology was maintained with specific modifications to screening, consenting, assessments, and group-based treatments to be delivered in remote (telehealth) format in response to COVID-19 restrictions. Results: Study enrollment was paused in March 2020 for five months to revise operations manuals, pilot remote treatment sessions for accuracy and fidelity, complete programming of REDCap assent/consent and assessment materials, train study staff for new procedures and obtain regulatory approvals. The trial was relaunched and has been successfully implemented in remote format since July 2020. Trial metrics thus far demonstrate a consistent rate of enrollment, strong attendance at remote treatment sessions, high retention rates and high treatment fidelity after protocol adaptations were implemented. Conclusions: Preliminary findings indicate that FIT Teens protocol adaptations from in-person to remote are feasible and allowed for sustained enrollment, retention, and treatment fidelity comparable to the in-person format. Methodologic and statistical considerations resulting from the adaptations are discussed as well as implications for interpretation of results upon completion of the trial.
RESUMO
Despite the increasing popularity of e-cigarettes, their long-term health effects remain unknown. In animal models, exposure to e-cigarette has been reported to result in pulmonary and cardiovascular injury, and in humans, the acute use of e-cigarettes increases heart rate and blood pressure and induces endothelial dysfunction. In both animal models and humans, cardiovascular dysfunction associated with e-cigarettes has been linked to reactive aldehydes such as formaldehyde and acrolein generated in e-cigarette aerosols. These aldehydes are known products of heating and degradation of vegetable glycerin (VG) present in e-liquids. Here, we report that in mice, acute exposure to a mixture of propylene glycol:vegetable glycerin (PG:VG) or to e-cigarette-derived aerosols significantly increased the urinary excretion of acrolein and glycidol metabolitesâ3-hydroxypropylmercapturic acid (3HPMA) and 2,3-dihydroxypropylmercapturic acid (23HPMA)âas measured by UPLC-MS/MS. In humans, the use of e-cigarettes led to an increase in the urinary levels of 23HPMA but not 3HPMA. Acute exposure of mice to aerosols derived from PG:13C3-VG significantly increased the 13C3 enrichment of both urinary metabolites 13C3-3HPMA and 13C3-23HPMA. Our stable isotope tracing experiments provide further evidence that thermal decomposition of vegetable glycerin in the e-cigarette solvent leads to generation of acrolein and glycidol. This suggests that the adverse health effects of e-cigarettes may be attributable in part to these reactive compounds formed through the process of aerosolizing nicotine. Our findings also support the notion that 23HPMA, but not 3HPMA, may be a relatively specific biomarker of e-cigarette use.

After more than a decade of electronic cigarette (E-cig) use in the United States, uncertainty persists regarding E-cig use and long-term cardiopulmonary disease risk. As all E-cigs use propylene glycol and vegetable glycerin (PG-VG) and generate abundant saturated aldehydes, mice were exposed by inhalation to PG-VG-derived aerosol, formaldehyde (FA), acetaldehyde (AA), or filtered air. Biomarkers of exposure and cardiopulmonary injury were monitored by mass spectrometry (urine metabolites), radiotelemetry (respiratory reflexes), isometric myography (aorta), and flow cytometry (blood markers). Acute PG-VG exposure significantly affected multiple biomarkers including pulmonary reflex (decreased respiratory rate, -50%), endothelium-dependent relaxation (-61.8 ± 4.2%), decreased WBC (-47 ± 7%), and, increased RBC (+6 ± 1%) and hemoglobin (+4 ± 1%) versus air control group. Notably, FA exposure recapitulated the prominent effects of PG-VG aerosol on pulmonary irritant reflex and endothelial dysfunction, whereas AA exposure did not. To attempt to link PG-VG exposure with FA or AA exposure, urinary formate and acetate levels were measured by GC-MS. Although neither FA nor AA exposure altered excretion of their primary metabolite, formate or acetate, respectively, compared with air-exposed controls, PG-VG aerosol exposure significantly increased post-exposure urinary acetate but not formate. These data suggest that E-cig use may increase cardiopulmonary disease risk independent of the presence of nicotine and/or flavorings. This study indicates that FA levels in tobacco product-derived aerosols should be regulated to levels that do not induce biomarkers of cardiopulmonary harm. There remains a need for reliable biomarkers of exposure to inhaled FA and AA.NEW & NOTEWORTHY Use of electronic cigarettes (E-cig) induces endothelial dysfunction (ED) in healthy humans, yet the specific constituents in E-cig aerosols that contribute to ED are unknown. Our study implicates formaldehyde that is formed in heating of E-cig solvents (propylene glycol, PG; vegetable glycerin, VG). Exposure to formaldehyde or PG-VG-derived aerosol alone stimulated ED in female mice. As ED was independent of nicotine and flavorants, these data reflect a "universal flaw" of E-cigs that use PG-VG.Listen to this article's corresponding podcast at https://ajpheart.podbean.com/e/e-cigarettes-aldehydes-and-endothelial-dysfunction/.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. Exposure to air pollution, specifically particulate matter of diameter ≤2.5 µm (PM2.5), is a well-established risk factor for CVD. However, the contribution of gaseous pollutant exposure to CVD risk is less clear. OBJECTIVE: To examine the vascular effects of exposure to individual volatile organic compounds (VOCs) and mixtures of VOCs. METHODS: We measured urinary metabolites of acrolein (CEMA and 3HPMA), 1,3-butadiene (DHBMA and MHBMA3), and crotonaldehyde (HPMMA) in 346 nonsmokers with varying levels of CVD risk. On the day of enrollment, we measured blood pressure (BP), reactive hyperemia index (RHI - a measure of endothelial function), and urinary levels of catecholamines and their metabolites. We used generalized linear models for evaluating the association between individual VOC metabolites and BP, RHI, and catecholamines, and we used Bayesian Kernel Machine Regression (BKMR) to assess exposure to VOC metabolite mixtures and BP. RESULTS: We found that the levels of 3HPMA were positively associated with systolic BP (0.98 mmHg per interquartile range (IQR) of 3HPMA; CI: 0.06, 1.91; P = 0.04). Stratified analysis revealed an increased association with systolic BP in Black participants despite lower levels of urinary 3HPMA. This association was independent of PM2.5 exposure and BP medications. BKMR analysis confirmed that 3HPMA was the major metabolite associated with higher BP in the presence of other metabolites. We also found that 3HPMA and DHBMA were associated with decreased endothelial function. For each IQR of 3HPMA or DHBMA, there was a -4.4% (CI: -7.2, -0.0; P = 0.03) and a -3.9% (CI: -9.4, -0.0; P = 0.04) difference in RHI, respectively. Although in the entire cohort the levels of several urinary VOC metabolites were weakly associated with urinary catecholamines and their metabolites, in Black participants, DHBMA levels showed strong associations with urinary norepinephrine and normetanephrine levels. DISCUSSION: Exposure to acrolein and 1,3-butadiene is associated with endothelial dysfunction and may contribute to elevated risk of hypertension in participants with increased sympathetic tone, particularly in Black individuals.

OBJECTIVE: Juvenile-onset fibromyalgia (JFM) is a chronic debilitating pain condition that negatively impacts physical, social and academic functioning. Cognitive-behavioral therapy (CBT) is beneficial in reducing functional disability among adolescents with JFM but has only a modest impact on pain reduction and does not improve physical exercise participation. This randomized controlled trial (RCT) aims to test whether a novel intervention that combines CBT with specialized neuromuscular exercise training (the Fibromyalgia Integrative Training program for Teens "FIT Teens") is superior to CBT alone or a graded aerobic exercise (GAE) program. DESIGN/METHODS: This 3-arm multi-site RCT will examine the efficacy of the FIT Teens intervention in reducing functional disability (primary outcome) and pain intensity (secondary outcome), relative to CBT or GAE. All interventions are 8-weeks (16 sessions) in duration and are delivered in small groups of 4-6 adolescents with JFM. A total of 420 participants are anticipated to be enrolled across seven sites with approximately equal allocation to each treatment arm. Functional disability and average pain intensity in the past week will be assessed at baseline, post-treatment and at 3-, 6-, 9- and 12-month follow-up. The 3-month follow-up is the primary endpoint to evaluate treatment efficacy; longitudinal assessments will determine maintenance of treatment gains. Changes in coping, fear of movement, biomechanical changes and physical fitness will also be evaluated. CONCLUSIONS: This multi-site RCT is designed to evaluate whether the combined FIT Teens intervention will have significantly greater effects on disability and pain reduction than CBT or GAE alone for youth with JFM.

PURPOSE OF REVIEW: Tobacco smoking is the most significant modifiable risk factor in the development of cardiovascular disease (CVD). Exposure to mainstream cigarette smoke (MCS) is associated with CVD through the development of endothelial dysfunction, a condition characterized by an imbalance of vasoactive factors in the vasculature. This dysfunction is thought to be induced in part by aldehydes generated at high levels in MCS. RECENT FINDINGS: Electronic cigarettes (e-cigs) may also pose CVD risk. Although the health effects of e-cigs are still largely unknown, the presence of aldehydes in e-cig aerosol suggests that e-cigs may induce adverse cardiovascular outcomes similar to those seen with MCS exposure. Herein, we review studies of traditional and emerging tobacco product use, shared harmful and potentially harmful constituents, and measures of biomarkers of harm (endothelial dysfunction) to examine a potential and distinct role of aldehydes in cardiovascular harm associated with cigarette and e-cig use.

Although crotonaldehyde (CR) is an abundant α,ß-unsaturated aldehyde in mainstream cigarette smoke (MCS), the cardiovascular toxicity of inhaled CR is largely unexplored. Thus, male C57BL/6 J mice were exposed acutely (1 h, 6 h, and 4d) and chronically (12 weeks) to CR (at levels relevant to MCS; 1 and 3 ppm), and cardiovascular and systemic outcomes were measured in vivo and in vitro. Diastolic blood pressure was decreased (hypotension) by both acute and chronic CR exposure. Vascular toxicity of inhaled CR was quantified in isolated aorta in response to agonists of contraction (phenylephrine, PE) and relaxation (acetylcholine, ACh; sodium nitroprusside, SNP). Although no change in contractility was observed, ACh-induced relaxations were augmented after both acute and chronic CR exposures whereas SNP-induced relaxation was enhanced only following 3 ppm CR exposure. Because CR is a known agonist of the transient receptor potential ankyrin 1 (TRPA1) channel, male TRPA1-null mice were exposed to air or CR (4d, 1 ppm) and aortic function assessed in vitro. CR exposure had no effect on TRPA1-null aortic function indicating a role of TRPA1 in CR effects in C57BL/6 J mice. Notably, CR exposure (4d, 1 ppm) had no effect on aortic function in female C57BL/6 J mice. This study shows that CR inhalation exposure induces real-time and persistent vascular changes that promote hypotension-a known risk factor for stroke. Because of continued widespread exposures of humans to combustion-derived CR (environmental and tobacco products), CR may be an important cardiovascular disease risk factor.

OBJECTIVE: The current study tested the utility of the PROMIS Pediatric Pain Interference (PPI) in relation to the widely-used Functional Disability Inventory (FDI) in a small-scale clinical trial. METHODS: Forty youth with juvenile fibromyalgia (JFM) were randomized to either CBT only or a combined CBT and neuromuscular exercise group (i.e., FIT Teens). Participants completed the PPI and FDI at baseline, post-treatment, and three-month follow-up. RESULTS: The PPI and FDI were significantly correlated at baseline (r = .51) and post treatment (r = .53), and demonstrated similar improvements (d PPI = .87, d FDI = 1.22, p < .05) at post-treatment following FIT Teens. Following CBT only, neither the PPI nor the FDI improved significantly. CONCLUSIONS: The PPI may be appropriate for use in non-pharmacologic interventions for pediatric pain.

Juvenile-onset fibromyalgia (JFM) is typically diagnosed in adolescence and characterized by widespread pain and marked functional impairment. The long-term impact of JFM into adulthood is poorly understood. The objectives of this study were to describe physical and psychosocial outcomes of youth diagnosed with JFM in early adulthood (â¼8-year follow-up), examine longitudinal trajectories of pain and depressive symptoms from adolescence to young adulthood, and examine the impact of pain and depressive symptoms on physical functioning over time. Participants were 97 youth with JFM enrolled in a prospective longitudinal study in which pain symptoms, and physical and psychosocial functioning were assessed at 4 time points over approximately 8 years. At the time 4 follow-up (Mage = 24.2 years), the majority continued to suffer from pain and impairment in physical, social, and psychological domains. However, trajectories of pain and emotional symptoms showed varying patterns. Longitudinal analysis using growth mixture modeling revealed 2 pain trajectories (Steady Improvement and Rapid Rebounding Improvement), whereas depressive symptoms followed 3 distinct trajectories (Low-Stable, Improving, and Worsening). Membership in the Worsening Depressive symptoms group was associated with poorer physical functioning over time (P < 0.001) compared with the Low-Stable and Improving groups. This study offers evidence that although JFM symptoms persist for most individuals, pain severity tends to decrease over time. However, depressive symptoms follow distinct trajectories that indicate subgroups of JFM. In particular, JFM patients with worsening depressive symptoms showed decreasing physical functioning and may require more intensive and consistent intervention to prevent long-term disability.

BACKGROUND: Pediatric functional abdominal pain disorders are common, costly, and disabling. Clinical anxiety is highly prevalent and is associated with increased pain and functional disability. Thus, a psychological screening process is recommended but is infrequently used in current practice. METHODS: A screening process for patient-reported anxiety (Screen for Child Anxiety and Related Disorders), functional disability (Functional Disability Inventory), and pain levels was implemented in a large gastroenterology division within a major medical center. Quality improvement methods and traditional analytic approaches were used to test the feasibility and outcomes of routine screening in patients ages 8 to 18 with abdominal pain. RESULTS: Screening rates increased from <1% to >80%. A total of 1291 patients who reported having abdominal pain completed the screening during the first 6 months. Clinically significant anxiety (43.1%), at least moderate disability (45%), and elevated pain (61.5%) were common in children with abdominal pain. The presence of clinically significant anxiety corresponded with higher pain and pain-related disability. Twenty-one percent of youth had clinical elevations in all 3 areas. In such instances, medical providers received an automated prompt to tailor care, including to consider a psychological referral. After the project implementation, psychological referral rates increased from 8.3 per 1000 patients to 15.2 per 1000 patients. CONCLUSIONS: Systematic screening for anxiety, pain, and pain-related disability as a routine part of medical care can be reliably implemented with clinically meaningful results. Future directions include examining the role of anxiety over the long-term and reducing clinician burden.

OBJECTIVE: To examine the differential presentation(s) of psychological and health-related outcomes in young adults with juvenile-onset fibromyalgia (FM) with and without a history of trauma, compared to healthy controls. METHODS: In total, 110 participants (86 with juvenile-onset FM and 24 healthy controls, with a mean age of 23.4 years) completed a structured clinical interview to assess for trauma and psychological comorbidities, as well as self-report questionnaires on pain, physical functioning, and health care utilization. RESULTS: Of the juvenile-onset FM participants, 37% (n = 32) reported a history of trauma. Three group comparisons (i.e., juvenile-onset FM with trauma versus juvenile-onset FM with no trauma versus healthy controls) revealed that juvenile-onset FM participants significantly differed from healthy controls on all psychological and health-related outcomes. Further, although juvenile-onset FM participants with and without a history of trauma did not significantly differ on pain and physical functioning, juvenile-onset FM participants with a history of trauma were significantly more likely to have psychological comorbidities. CONCLUSION: This is the first controlled study to examine the differential outcomes between juvenile-onset FM participants with and without a history of trauma. Group comparisons between juvenile-onset FM participants and healthy controls were consistent with previous research. Further, our findings indicate that juvenile-onset FM participants with a history of trauma experience greater psychological, but not physical, impairment than juvenile-onset FM participants without a history of trauma.

OBJECTIVES: To evaluate the utility of the 2010 American College of Rheumatology (ACR) adult fibromyalgia criteria for use in adolescents with juvenile fibromyalgia (JFM). STUDY DESIGN: Participants included 47 adolescent girls diagnosed with JFM (mean age = 15.3 years) and 48 age- and sex-matched adolescents (mean age = 15.0 years) with localized chronic pain (eg, headaches or abdominal pain). A trained examiner administered the Widespread Pain Index and Symptom Severity measures and also completed a manual tender point exam. Clinicians completed a form indicating the presence of active JFM per Yunus and Masi (1985) criteria, the only available and most commonly used measure for JFM. Criterion validity analysis was performed as well as t tests comparing symptoms between JFM and controls. RESULTS: With the Yunus and Masi criteria used as the gold standard, the 2010 ACR fibromyalgia criteria showed a sensitivity of 89.4% and specificity of 87.5%. CONCLUSION: The 2010 ACR measure appears to be a valuable tool for the identification of JFM. However, a slight modification to the 2010 ACR measure and inclusion of a clinical exam is recommended.

PURPOSE: Juvenile-onset fibromyalgia (JFM) affects physical, social, and emotional functioning. Little is known about how social support and social interactions are impacted in the transition to young adulthood for patients diagnosed with JFM. METHODS: Young adults (Mage = 21.6) diagnosed with JFM during adolescence (N = 94) and matched healthy controls (N = 33) completed measures of social network size and diversity, perceived social support, physical functioning, and depressive symptoms as part of a cross-sectional survey study. RESULTS: No difference in social network diversity was found, although JFM patients reported fewer total people within their social networks. JFM patients reported poorer emotional and tangible support and fewer positive social interactions than healthy controls. After controlling for condition and pain intensity, the level of perceived social support was a significant predictor of physical functioning and depressive symptoms, whereas social network size also contributed uniquely to physical functioning. CONCLUSIONS: Given the developmental importance of social support in adolescence and young adulthood, interventions should include methods of improving social support into fibromyalgia management.

OBJECTIVE: Adolescents with juvenile-onset fibromyalgia (JFM) have increased rates of psychiatric disorders, but to our knowledge no studies have examined psychiatric disorders in adolescents with JFM when they enter young adulthood. This study examined the prevalence of psychiatric disorders in young adults diagnosed with JFM during adolescence and the relationship between mental health diagnoses and physical functioning. METHODS: Ninety-one young adults (mean age 21.60, SD 1.96) with a history of JFM being followed as part of a prospective longitudinal study and 30 matched healthy controls (mean age 21.57, SD 1.55) completed a structured interview of psychiatric diagnoses and a self-report measure of physical impairment. RESULTS: Young adults with a history of JFM were more likely to have current and lifetime histories of anxiety disorders (70.3% and 76.9%, respectively) compared with controls (33.3% for both, both p < 0.001). Individuals with JFM were also more likely to have current and lifetime histories of major mood disorders (29.7% and 76.9%, respectively) compared with controls (10% and 40%, p < 0.05). The presence of a current major mood disorder was significantly related to impairment in physical functioning [F (1, 89) = 8.30, p < 0.01] and role limitations attributable to a physical condition [F (1, 89) = 7.09, p < 0.01]. CONCLUSION: Psychiatric disorders are prevalent in young adulthood for individuals with a history of JFM, and a current major mood disorder is associated with greater physical impairment. Greater attention to early identification and treatment of mood disorders in patients with JFM is warranted.

BACKGROUND: Functional abdominal pain (FAP) is associated with significant anxiety and impairment. Prior investigations of child anxiety in youth with FAP are generally limited by small sample sizes, based on child report, and use lengthy diagnostic tools. It is unknown whether a brief anxiety-screening tool is feasible, whether parent and child reports of anxiety are congruent, and whether parent and child agreement of child anxiety corresponds to increased impairment. The purpose of this investigation was to examine anxiety characteristics in youth with FAP using parent and child reports. Parent-child agreement of child anxiety symptoms was examined in relation to pain and disability. METHODS: One hundred patients with FAP (8-18 years of age) recruited from pediatric gastroenterology clinics completed measures of pain intensity (Numeric Rating Scale) and disability (Functional Disability Inventory). Patients and caregivers both completed a measure of child anxiety characteristics (Screen for Child Anxiety and Related Disorders). RESULTS: Clinically significant anxiety symptoms were more commonly reported by youth (54%) than their parents (30%). Panic/somatic symptoms, generalized anxiety, and separation anxiety were most commonly endorsed by patients, whereas generalized anxiety, separation anxiety, and school avoidance were most commonly reported by parents. The majority (65%) of parents and children agreed on the presence (26%) or absence (39%) of clinically significant anxiety. Parent-child agreement of clinically significant anxiety was related to increased impairment. CONCLUSIONS: A brief screening instrument of parent and child reports of anxiety can provide clinically relevant information for comprehensive treatment planning in children with FAP.

The primary objective of this study was to estimate a clinically significant and quantifiable change in functional disability to identify treatment responders in a clinical trial of cognitive-behavioral therapy (CBT) for youth with juvenile fibromyalgia (JFM). The second objective was to examine whether baseline functional disability (Functional Disability Inventory), pain intensity, depressive symptoms (Children's Depression Inventory), coping self-efficacy (Pain Coping Questionnaire), and parental pain history predicted treatment response in disability at 6-month follow-up. Participants were 100 adolescents (11-18 years of age) with JFM enrolled in a recently published clinical trial comparing CBT to a fibromyalgia education (FE) intervention. Patients were identified as achieving a clinically significant change in disability (i.e., were considered treatment responders) if they achieved both a reliable magnitude of change (estimated as a > or = 7.8-point reduction on the FDI) using the Reliable Change Index, and a reduction in FDI disability grade based on established clinical reference points. Using this rigorous standard, 40% of patients who received CBT (20 of 50) were identified as treatment responders, compared to 28% who received FE (14 of 50). For CBT, patients with greater initial disability and higher coping efficacy were significantly more likely to achieve a clinically significant improvement in functioning. Pain intensity, depressive symptoms, and parent pain history did not significantly predict treatment response. Estimating clinically significant change for outcome measures in behavioral trials sets a high bar but is a potentially valuable approach to improve the quality of clinical trials, to enhance interpretability of treatment effects, and to challenge researchers to develop more potent and tailored interventions.

OBJECTIVE: This prospective longitudinal study examined the long-term physical and psychosocial outcomes of adolescents with juvenile-onset fibromyalgia (JFM), compared with healthy control subjects, into early adulthood. METHODS: Adolescent patients with JFM initially seen at a pediatric rheumatology clinic (n = 94) and age- and gender-matched healthy control subjects (n = 33) completed online measures of demographic characteristics, pain, physical functioning, mood symptoms, and health care utilization at â¼6 years' follow-up (mean age: 21 years). A standard in-person tender-point examination was conducted. RESULTS: Patients with JFM had significantly higher pain (P < .001), poorer physical function (P < .001), greater anxiety (P < .001) and depressive symptoms (P < .001), and more medical visits (P < .001)than control subjects. The majority (>80%) of JFM patients continued to experience fibromyalgia symptoms into early adulthood, and 51.1% of the JFM sample met American College of Rheumatology criteria for adult fibromyalgia at follow-up. Patients with JFM were more likely than control subjects to be married and less likely to obtain a college education. CONCLUSIONS: Adolescent patients with JFM have a high likelihood of continued fibromyalgia symptoms into young adulthood. Those who met criteria for fibromyalgia in adulthood exhibited the highest levels of physical and emotional impairment. Emerging differences in educational attainment and marital status were also found in the JFM group. JFM is likely to be a long-term condition for many patients, and this study for the first time describes the wide-ranging impact of JFM on a variety of physical and psychosocial outcomes that seem to diverge from their same-age peers.

BACKGROUND: Inherited epidermolysis bullosa (EB) comprises a group of rare disorders that have multi-system effects and patients present with a number of both acute and chronic pain care needs. Effects on quality of life are substantial. Pain and itching are burdensome daily problems. Experience with, and knowledge of, the best pain and itch care for these patients is minimal. Evidence-based best care practice guidelines are needed to establish a base of knowledge and practice for practitioners of many disciplines to improve the quality of life for both adult and pediatric patients with EB. METHODS: The process was begun at the request of Dystrophic Epidermolysis Bullosa Research Association International (DEBRA International), an organization dedicated to improvement of care, research and dissemination of knowledge for EB patients worldwide. An international panel of experts in pain and palliative care who have extensive experience caring for patients with EB was assembled. Literature was reviewed and systematically evaluated. For areas of care without direct evidence, clinically relevant literature was assessed, and rounds of consensus building were conducted. The process involved a face-to-face consensus meeting that involved a family representative and methodologist, as well as the panel of clinical experts. During development, EB family input was obtained and the document was reviewed by a wide variety of experts representing several disciplines related to the care of patients with EB. RESULTS: The first evidence-based care guidelines for the care of pain in EB were produced. The guidelines are clinically relevant for care of patients of all subtypes and ages, and apply to practitioners of all disciplines involved in the care of patients with EB. When the evidence suggests that the diagnosis or treatment of painful conditions differs between adults and children, it will be so noted. CONCLUSIONS: Evidence-based care guidelines are a means of standardizing optimal care for EB patients, whose disease is often times horrific in its effects on quality of life, and whose care is resource-intensive and difficult. The guideline development process also highlighted areas for research in order to improve further the evidence base for future care.
