Abstract
Background Although smoking is a known potential contributor to back pain, there is still a lack of quantitative studies on the effects of different doses on back pain (BP) occurrence, including a lack of a longitudinal cohorts. To address this gap, we aimed to investigate the association between various smoking-related exposures and back pain incidence to advance global efforts toward smoking cessation and guide primary prevention of BP. Methods In this prospective cohort study, we retrieved data on 438 510 patients from the UK Biobank who were free of back pain and who were recruited in 2006-2010, and followed them up from baseline through 1 April 2022. We extracted data on smoking-related exposures, including smoking status (SS), number of cigarettes smoked daily (CPD), and pack-years of own smoking (PY) and examined back pain incidence as an outcome. We used a Cox proportional hazard model adjusted for several covariates, multiple imputation methods, and population attribution fraction. Results During the median follow-up of 12.98 years, 31 467 participants developed BP, with incidence rates in former and current smokers of 1.13 (95% confidence interval (CI) = 1.10-1.16, P < 0.000) and 1.50 (95% CI = 1.45-1.56, P < 0.000), respectively. The hazard ratios (HRs) of participants who smoked more than 30 CPD and those with more than 30 PY were 1.45 (95% CI = 1.36-1.55, P < 0.000) and 1.45 (95% CI = 1.40-1.50, P < 0.000), respectively. Relative to male, female smokers were at more risk of developing BP. Not smoking, quitting smoking, and reducing CPD and PY could lower the BP risk by 7.8%, 5.4%, 9.8%, and 18.0%, respectively. Conclusions Ever smoking, higher cigarette consumption daily, and increased smoking intensity were associated with an increased BP risk. This association was stronger in female smokers. Not smoking, smoking cessation, and reducing smoking volume and intensity were effective measures to prevent BP occurrence.

Abstract
Apart from aging process, adult intervertebral disc (IVD) undergoes various degenerative processes. However, the nicotine has not been well identified as a contributing etiology. According to a few studies, nicotine ingestion through smoking, air or clothing may significantly accumulate in active as well as passive smokers. Since nicotine has been demonstrated to adversely impact various physiological processes, such as sympathetic nervous system, leading to impaired vasculature and cellular apoptosis, we aimed to investigate whether nicotine could induce IVD degeneration. In particular, we evaluated dose-dependent impact of nicotine in vitro to simulate its chronic accumulation, which was later treated by platelet-derived biomaterials (PDB). Further, during in vivo studies, mice were subcutaneously administered with nicotine to examine IVD-associated pathologic changes. The results revealed that nicotine could significantly reduce chondrocytes and chondrogenic indicators (Sox, Col II and aggrecan). Mice with nicotine treatment also exhibited malformed IVD structure with decreased Col II as well as proteoglycans, which was significantly increased after PDB administration for 4 weeks. Mechanistically, PDB significantly restored the levels of IGF-1 signaling proteins, particularly pIGF-1 R, pAKT, and IRS-1, modulating ECM synthesis by chondrocytes. Conclusively, the PDB impart reparative and tissue regenerative processes by inhibiting nicotine-initiated IVD degeneration, through regulating IGF-1/AKT/IRS-1 signaling axis.

Abstract
Objective To describe current tobacco use among patients with newly confirmed fibromyalgia and evaluate the association between tobacco use status and severity of reported pain and other fibromyalgia symptoms. Patients and Methods Participants in this study were adult patients (N=1068) with fibromyalgia who met American College of Rheumatology 2010/2011 clinical criteria for fibromyalgia at the time of initial presentation to a Midwest fibromyalgia clinic (June 1, 2018, through May 31, 2019). Multiple linear regression analyses were performed to assess the association of tobacco use status with the Widespread Pain Index (WPI) and Symptom Severity Scale (SSS) scores. Covariates included in these analyses included age, sex, body mass index, depression, opioid medication use, and use of fibromyalgia-specific pharmacotherapy. Results The patients were largely women (87.0%; n=929), white (87.9%; n=939), and with an average ± SD age of 46.6±13.9 years. The WPI and SSS scores were significantly greater in current tobacco users compared with never tobacco users (WPI effect estimate [EE] = 1.03; 95% CI, 0.30 to 1.76; type III P=.020; SSS EE = 0.47; 95% CI, 0.11 to 0.84; type III P=.036). The WPI score was negatively associated with age (EE = −0.02 per year; 95% CI, −0.03 to −0.001 per year; P=.037) and no use of opioid medication (EE = −1.08; 95% CI, −1.59 to −0.57; P<.001) while positively associated with higher body mass index (EE = 0.03 per 1 kg/m2; 95% CI, 0.001 to 0.06 per kg/m2; P=.04) and higher Patient Health Questionnaire-9 score (EE = 0.12; 95% CI, 0.08 to 0.16; P<.001). Conclusion The results of our study suggest that tobacco use is associated with greater pain and other symptom severity in patients with fibromyalgia. These findings have important clinical and research implications for patients with fibromyalgia who use tobacco and who may benefit from early identification and timely implementation of tobacco cessation treatment to decrease pain and improve overall quality of life.

Abstract
Rates of chronic pain and cigarette smoking are each substantially higher among people living with HIV (PLWH) than in the general population. The goal of these analyses was to examine the prevalence and impact of comorbid chronic pain and cigarette smoking among PLWH. Participants included 3289 PLWH (83% male) who were recruited from five HIV clinics. As expected, the prevalence of smoking was higher among PLWH with chronic pain (41.9%), than PLWH without chronic pain (26.6%, p < .0001), and the prevalence of chronic pain was higher among current smokers (32.9%), than among former (23.6%) or never (17%) smokers (ps < .0001). PLWH who endorsed comorbid chronic pain and smoking (vs. nonsmokers without chronic pain) were more likely to report cocaine/crack and cannabis use, be prescribed long-term opioid therapy, and have virologic failure, even after controlling for relevant sociodemographic and substance-related variables (ps < .05). These results contribute to a growing empirical literature indicating that chronic pain and cigarette smoking frequently co-occur, and extend this work to a large sample of PLWH. Indeed, PLWH may benefit from interventions that are tailored to address bidirectional pain-smoking effects in the context of HIV.

Abstract
BACKGROUND The additive effect of experiencing chronic pain in the context of nicotine addiction places smokers with chronic pain at elevated risk for experiencing physical and mental health problems. Isolating factors that explain linkages between pain and health-related outcomes among smokers with chronic pain is an important next step. Therefore, the current study examined the explanatory role of anxiety sensitivity in relations between pain intensity and current opioid misuse, severity of opioid dependence, tobacco-related problems, and anxiety/depressive symptoms. METHOD Participants were 187 (Mage = 39.02, SD = 9.94, 74.9% female) daily smokers with chronic pain who completed a battery of self-report measures on pain experience, anxiety sensitivity, tobacco and opioid use, and anxiety/depression symptoms. Indirect effect analyses were conducted to examine anxiety sensitivity as a mediator of the relations between pain intensity and health-related outcomes. RESULTS A significant indirect effect emerged for pain intensity, through anxiety sensitivity, on opioid misuse (ab = 0.83, SE = 0.24, 95% CI [0.39, 1.34], CSE = 0.17), severity of opioid dependence (ab = 0.17, SE = 0.05, 95% CI [0.08, 0.26], CSE = 0.16), tobacco use problems (ab = 0.16, SE = 0.06, 95% CI [0.07, 0.28], CSE = 0.11), and anxiety/depressive symptoms (ab = 0.20, SE = 0.06, 95% CI [0.10, 0.31], CSE = 0.19). CONCLUSION The current investigation highlights the potential importance of anxiety sensitivity in terms of the experience of pain with severity of substance use and anxiety/depressive symptoms among smokers with chronic pain.

Abstract
INTRODUCTION Smoking is associated with several diseases and affects the immune system. Recently, published data demonstrate an involvement of T helper 17 cells (Th17) and regulatory T cells (Tregs) in the pathogenesis of chronic pain and pain intensity. The role of these T-cell subsets in smoking patients with chronic pain is nebulous so far. We therefore analyzed Th17 cells and Tregs in smokers and nonsmokers with chronic pain. METHODS Analyses of T-cell subsets, mRNA expression and T-cell related cytokine profiles were done in 44 patients with chronic pain. Twenty-two of these patients were smokers. Numbers of T-cell subsets were quantified by flow cytometry. mRNA expression of the Th17- (RAR-related orphan receptor gamma) and Treg (forkhead box protein P3)-specific transcription factors was determined by quantitative real-time PCR, and levels of cytokines were measured by Human Cytokine Multiplex Immunoassay. RESULTS Compared to nonsmokers, smokers showed significantly enhanced pain levels. On cellular basis, the number of pro-inflammatory Th17 cells (smokers: 2.2 ± 2.5% vs. nonsmokers: 0.5 ± 0.4%; p = .04) was increased, whereas the number of anti-inflammatory Tregs (smokers: 2.5 ± 0.9% vs. nonsmokers: 3.1 ± 1.1%; p = .02) was significantly decreased, resulting in an altered Th17/Treg ratio (Th17/Treg ratio: 0.9 ± 1.0 in smokers vs. 0.2 ± 0.1 in nonsmokers; p < .01). These findings were confirmed by quantitative real-time PCR. Analyses of cytokines revealed only marginal changes. CONCLUSIONS In patients with chronic pain, smoking is associated with enhanced pain levels together with an imbalance of the Th17/Treg ratio. The shift of the Th17/Treg ratio toward inflammation may explain in part the increased pain intensity in these patients. IMPLICATIONS Smoking is associated with increased pain levels and a pro-inflammatory Th17/Treg shift. The altered Th17/Treg ratio in smoking patients with chronic pain may partly explain their increased pain intensity. GERMAN CLINICAL TRIAL REGISTER (DRKS) Registration Trial DRKS00005954.

Abstract
BACKGROUND Smoking adversely impacts pain-related outcomes of spinal cord stimulation (SCS). However, the proportion of SCS patients at risk of worse outcomes is limited by an incomplete knowledge of smoking prevalence in this population. Thus, the primary aim of this systematic review is to determine the prevalence of smoking in adults with chronic pain treated with SCS. METHODS A comprehensive search of databases from 1 January 1980 to 3 January 2019 was conducted. Eligible study designs included (1) randomized trials; (2) prospective and retrospective cohort studies; and (3) cross-sectional studies. The risk of bias was assessed using a tool specifically developed for prevalence studies. A total of 1619 records were screened, 19 studies met inclusion criteria, and the total number of participants was 10 838. RESULTS Thirteen studies had low or moderate risk of bias, and six had a high risk of bias. All 19 studies reported smoking status and the pooled prevalence was 38% (95% CI 30% to 47%). The pooled prevalence in 6 studies of peripheral vascular diseases was 56% (95% CI 42% to 69%), the pooled prevalence of smoking in 11 studies of lumbar spine diagnoses was 28% (95% CI 20% to 36%) and the pooled prevalence in 2 studies of refractory angina was 44% (95% CI 31% to 58%). CONCLUSIONS The estimated prevalence of smoking in SCS patients is 2.5 times greater than the general population. Future research should focus on development, testing and deployment of tailored smoking cessation treatments for SCS patients.

Abstract
The pack-years formula is a widely used estimate of lifetime tobacco smoking exposure, and greater pack-years have been associated with greater risk of chronic pain development and poorer pain-related outcomes among smokers with chronic pain. The pathophysiology underlying these associations is poorly understood. Regular tobacco smoking exposure may dysregulate homeostatic pain processes, producing an allostatic state of pain facilitation. Maladaptive pain mechanisms, such as central and peripheral sensitization, are chronic pain risk factors. Yet no published research has examined the relation between lifetime-smoking exposure and dysregulated pain processing. The current study used hierarchical linear regression analyses to test pack-years of tobacco smoking as a predictor of (a) pain reporting (current pain severity, pain frequency in the last 180 days) among a sample of 228 daily smokers without chronic pain, and (b) experimental capsaicin-induced pain reactivity (pain intensity, area of flare, mechanical pain sensitivity, and area of mechanical hyperalgesia) among 101 daily smokers without chronic pain. As hypothesized, results indicated that pack-years smoking was positively and significantly associated with current pain severity, past 180-day pain frequency, experimental pain intensity, mechanical pain sensitivity ratings, and area of mechanical hyperalgesia. Pack-years smoking was not significantly associated with neurogenic flare. These findings implicate central sensitization as a factor that may underlie the association between chronic tobacco smoking and increased risk for persistent pain.

Abstract
The immune system is critically involved in the development and maintenance of chronic pain. However, T cells, one of the main regulators of the immune response, have only recently become a focus of investigations on chronic pain pathophysiology. Emerging clinical data suggest that patients with chronic pain have a different phenotypic profile of circulating T cells compared to controls. At the preclinical level, findings on the function of T cells are mixed and differ between nerve injury, chemotherapy, and inflammatory models of persistent pain. Depending on the type of injury, the subset of T cells and the sex of the animal, T cells may contribute to the onset and/or the resolution of pain, underlining T cells as a major player in the transition from acute to chronic pain. Specific T cell subsets release mediators such as cytokines and endogenous opioid peptides that can promote, suppress, or even resolve pain. Inhibiting the pain-promoting functions of T cells and/or enhancing the beneficial effects of pro-resolution T cells may offer new disease-modifying strategies for the treatment of chronic pain, a critical need in view of the current opioid crisis.

Abstract
Although low-back pain is considered to be associated with cigarette smoking, the influence of cigarette smoking on the intervertebral discs (IVD) has not been confirmed. We established a rat model of passive cigarette smoking-induced IVD degeneration, and investigated the cytohistological changes in the IVD and the accompanying changes in gene expression. IVD from rats exposed to 8 weeks of passive cigarette smoking were stained with Elastica van Gieson, and exhibited marked destruction of the supportive structure of the reticular matrix in the nucleus pulposus (NP). Positive signals on safranin O, alcian blue, type II collagen and aggrecan staining were decreased in the destroyed structure. Safranin O and type II collagen signals were also decreased in the cartilage end-plate (CEP) after 4- and 8-weeks of cigarette smoking. In the CEP, the potential for apoptosis was increased significantly, as demonstrated by staining for single-strand DNA. However, there were no signs of apoptosis in the NP or annulus fibrosus cells. Based on these findings, we hypothesized that passive cigarette smoking-induced stress stimuli first affect the CEP through blood flow due to the histological proximity, thereby stimulating chondrocyte apoptosis and reduction of the extracellular matrix (ECM). This leads to reduction of the ECM in the NP, destroying the NP matrix, which can then progress to IVD degeneration.

[PMID: 29859349 PMCID: PMC6274599 DOI: 10.1016/j.spinee.2018.05.035] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 04/19/2018] [Accepted: 05/24/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Low back pain (LBP) is a common complaint in clinical practice of multifactorial origin. Although obesity has been thought to contribute to LBP primarily by altering the distribution of mechanical loads on the spine, the additional contribution of obesity-related conditions such as diabetes mellitus (DM) to LBP has not been thoroughly examined. PURPOSE To determine if there is a relationship between DM and LBP that is independent of body mass index (BMI) in a large cohort of adult survey participants. STUDY DESIGN Retrospective analysis of prospectively collected National Health and Nutrition Examination Survey (NHANES) data to characterize associations between LBP, DM, and BMI in adults subdivided into 6 subpopulations: normal weight (BMI 18.5-25), overweight (BMI 25-30), and obese (BMI >30) diabetics and nondiabetics. Diabetes was defined with glycohemoglobin A1c (HbA1c) ≥6.5%. PATIENT SAMPLE 11,756 participants from NHANES cohort. OUTCOME MEASURES Percentage of LBP reported. METHODS LBP reported in the 1999-2004 miscellaneous pain NHANES questionnaire was the dependent variable examined. Covariates included HbA1c, BMI, age, and family income ratio to poverty as continuous variables as well as race, gender, and smoking as binary variables. Individuals were further subdivided by weight class and diabetes status. Regression and graphical analyses were performed on the study population as a whole and also on subpopulations. RESULTS Increasing HbA1c did not increase the odds of reporting LBP in the full cohort. However, multivariate logistic regression of the 6 subpopulations revealed that the odds of LBP significantly increased with increasing HbA1c levels in normal weight diabetics. No other subpopulations reported significant relationships between LBP and HbA1c. LBP was also significantly associated with BMI for normal weight diabetics and also for obese subjects regardless of their DM status. CONCLUSIONS LBP is significantly related to DM status, but this relationship is complex and may interact with BMI. These results support the concept that LBP may be improved in normal weight diabetic subjects with improved glycemic control and weight loss, and that all obese LBP subjects may benefit from improved weight loss alone.

Abstract
BACKGROUND Past work has documented bidirectional associations between pain and cigarette smoking behaviors such that those who smoke evidence greater pain, and those in pain tend to smoke more. However, such work has not focused on the role of pain in relation to negative affect, which plays an important role during cessation attempts. OBJECTIVE The current study evaluated pain as a predictor of negative affect as well as level of interference associated with negative affect among individuals undergoing a self-guided quit attempt. METHODS Study variables were assessed via ecological momentary assessment (EMA) during the 2 weeks following a self-guided quit attempt. Participants included 54 daily smokers (33.3% female; Mage = 34.7, SD = 13.9). RESULTS There were statistically significant within-person associations of pain ratings with negative affect and interference due to negative affect, such that greater pain was associated with higher levels of each dependent variable. Additionally, there was a within-person effect of smoking status (i.e., smoking vs. abstinence, measured via EMA) on negative affect, but not ratings of interference; smoking was associated with greater negative affect. CONCLUSION These findings highlight the importance of bodily pain in relation to negative mood following a quit attempt. Clinically, the results suggest a greater focus on the experience of pain during quit attempts may be warranted.

Abstract
OBJECTIVES Smokers on chronic opioid therapy (COT) for noncancer pain use prescription opioids at higher dosages and are at increased risk for opioid misuse and dependence relative to nonsmokers. The current study aims to assess whether smoking is associated with problems and concerns with COT from the perspective of the patient. MATERIALS AND METHODS In a large sample (N=972) of adult patients prescribed opioids for chronic noncancer pain, we examined sex-specific associations between smoking status and patient perceptions of problems and concerns with COT using regression analyses, adjusting for covariates. RESULTS The sample self-identified as 27% current smokers, 44% former smokers, and 29% never smokers. Current smoking (vs. never smoking) was associated with increased odds of an opioid use disorder among males and females, and higher daily opioid dose among males only. Current and former smokers reported significantly fewer problems with opioids relative to never smokers, and this was driven primarily by lower endorsement of problems that are affected by the stimulant properties of nicotine (eg, difficulties thinking clearly, felt less alert or sleepy). DISCUSSION This study contributes to an understanding of perceived problems and concerns with COT among current, former, and never smokers with chronic noncancer pain. Results suggest that current and former smokers may be a difficult population to target to decrease COT, given that they perceive fewer problems with prescription opioid use, despite higher odds of having an opioid use disorder (males and females) and greater opioid doses (males only).

Abstract
STUDY DESIGN Retrospective analysis of prospective data. OBJECTIVE The aim of this study was to reveal baseline predictors of persistent postlaminoplasty neck pain. SUMMARY OF BACKGROUND DATA Axial neck pain is one of the most common complications after cervical laminoplasty; however, baseline predictors of persistent postlaminoplasty neck pain are unclear. METHODS We analyzed data from 156 patients who completed a 2-year follow-up after double-door laminoplasty for degenerative cervical myelopathy. Patients rated the average intensity of axial neck pain in the last month using an 11-point numerical rating scale preoperatively and at the 2-year follow-up. The dependent variable was the presence of moderate-to-severe neck pain (numerical rating scale ≥4) at the 2-year follow-up. The independent variables included patient characteristics, baseline radiological parameters, surgical variables, baseline axial neck pain intensity, and baseline functions, which were measured by the Japanese Orthopaedic Association score and the Short Form-36 survey (SF-36). Logistic regression analysis was performed to identify independent predictors of moderate-to-severe neck pain after laminoplasty. RESULTS At the 2-year follow-up, 51 patients (32%) had moderate-to-severe neck pain, and 106 patients (68%) had no or mild pain. Univariate analysis revealed that the ratio of cervical anterolisthesis, ratio of current smoking, baseline neck pain intensity, and baseline SF-36 Mental Component Summary differed significantly between the groups. Multivariate logistic regression analysis showed that independent predictors of moderate-to-severe neck pain at the 2-year follow-up include the presence of anterolisthesis, current smoking, moderate-to-severe baseline neck pain, and lower SF-36 Mental Component Summary. The presence of anterolisthesis and moderate-to-severe baseline neck pain were also associated with significantly poorer physical function after surgery. CONCLUSION The presence of anterolisthesis was associated not only with the highest odds ratio of persistent neck pain but also with significantly poorer functional outcomes. Indications for cervical laminoplasty should be carefully determined in patients with cervical anterolisthesis. LEVEL OF EVIDENCE 4.

Abstract
STUDY DESIGN This study is based on data from the 2009-2012 National Health Interview Survey (NHIS) of the civilian population of the United States. The NHIS focuses on a number of health conditions, including low back pain. OBJECTIVE The objective of this study is to explore behavior-related factors associated with low back pain in the US adult population, including leisure-time physical activity, alcohol use, tobacco use, sleep duration, and obesity. SUMMARY OF BACKGROUND DATA Low back pain is a prevalent musculoskeletal health disorder with profound impact on individuals, business, and society. Addressing behavior-related factors holds the potential to reduce the burden of low back pain on a societal basis. METHODS To account for the complex sampling design of the NHIS, the Taylor linearized variance estimation methods were used to conduct weighted descriptive statistics and multivariate logistic regression analyses in exploring the relationships between low back pain and a set of behavior-related risk factors. RESULTS This study shows associations between self-reported lower back pain and reported leisure-time physical inactivity, current or former smoking, current or former alcohol drinking, short sleep duration, and obesity. CONCLUSION This study identified a number of behavior-related factors that appear to have a significant relationship with low back pain. Public health policy makers and clinicians should consider these factors to reduce the burden of low back pain. This study supports the need for longitudinal study design in future research.

Abstract
Empirical evidence supporting the interplay between pain intensity and tobacco smoking has been growing. The current investigation advances this work in three important ways: (1) controlling for negative affectivity and gender; (2) examining pain intensity in smokers from a community sample, rather than specialized pain treatment centers; and, (3) studying smokers who are highly motivated to quit. Participants were adult smokers (N=112; 35% female; Mage=41.4, SD=13.1) participating in a larger study examining barriers to cessation during a self-guided quit attempt. At baseline, participants completed self-report measures on pain intensity and smoking severity outcomes. As hypothesized, more intense pain was significantly associated with all four smoking severity variables: years as a daily smoker, current cigarettes per day, cigarettes per day during the heaviest lifetime smoking period, and current level of nicotine dependence. These associations remained when taking into account the variance accounted for by gender and negative affectivity. These data provide evidence that more intense pain is related to more severe smoking behavior and nicotine dependence. Pain reduction could be an important target in regard to smokers with chronic pain.

Abstract
Practitioners are highly likely to encounter patients with concurrent use of nicotine products and opioid analgesics. Smokers present with more severe and extended chronic pain outcomes and have a higher frequency of prescription opioid use. Current tobacco smoking is a strong predictor of risk for nonmedical use of prescription opioids. Opioid and nicotinic-cholinergic neurotransmitter systems interact in important ways to modulate opioid and nicotine effects: dopamine release induced by nicotine is dependent on facilitation by the opioid system, and the nicotinic-acetylcholine system modulates self-administration of several classes of abused drugs-including opioids. Nicotine can serve as a prime for the use of other drugs, which in the case of the opioid system may be bidirectional. Opioids and compounds in tobacco, including nicotine, are metabolized by the cytochrome P450 enzyme system, but the metabolism of opioids and tobacco products can be complicated. Accordingly, drug interactions are possible but not always clear. Because of these issues, asking about nicotine use in patients taking opioids for pain is recommended. When assessing patient tobacco use, practitioners should also obtain information on products other than cigarettes, such as cigars, pipes, smokeless tobacco, and electronic nicotine delivery systems (ENDS, or e-cigarettes). There are multiple forms of behavioral therapy and pharmacotherapy available to assist patients with smoking cessation, and opioid agonist maintenance and pain clinics represent underutilized opportunities for nicotine intervention programs.

Effects of Tobacco Smoking on the Degeneration of the Intervertebral Disc: A Finite Element Study. PLoS One 2015; 10:e0136137.

Abstract
Tobacco smoking is associated with numerous pathological conditions. Compelling experimental evidence associates smoking to the degeneration of the intervertebral disc (IVD). In particular, it has been shown that nicotine down-regulates both the proliferation rate and glycosaminoglycan (GAG) biosynthesis of disc cells. Moreover, tobacco smoking causes the constriction of the vascular network surrounding the IVD, thus reducing the exchange of nutrients and anabolic agents from the blood vessels to the disc. It has been hypothesized that both nicotine presence in the IVD and the reduced solute exchange are responsible for the degeneration of the disc due to tobacco smoking, but their effects on tissue homeostasis have never been quantified. In this study, a previously presented computational model describing the homeostasis of the IVD was deployed to investigate the effects of impaired solute supply and nicotine-mediated down-regulation of cell proliferation and biosynthetic activity on the health of the disc. We found that the nicotine-mediated down-regulation of cell anabolism mostly affected the GAG concentration at the cartilage endplate, reducing it up to 65% of the value attained in normal physiological conditions. In contrast, the reduction of solutes exchange between blood vessels and disc tissue mostly affected the nucleus pulposus, whose cell density and GAG levels were reduced up to 50% of their normal physiological levels. The effectiveness of quitting smoking on the regeneration of a degenerated IVD was also investigated, and showed to have limited benefit on the health of the disc. A cell-based therapy in conjunction with smoke cessation provided significant improvements in disc health, suggesting that, besides quitting smoking, additional treatments should be implemented in the attempt to recover the health of an IVD degenerated by tobacco smoking.

Abstract
Introduction: We examined rates of smoking cessation and the effect of smoking cessation on pain and disability scores in a geriatric patient population. Methods: Prospectively maintained database records of 6779 patients treated for painful spinal disorders were examined. The mean duration of care was 8 months. Multivariate statistical analysis was performed with independent variables including smoking status, secondary gain status, gender, treatment type, depression, and age. Results: Of the patients seeking care for painful spinal disorders, 8.9% over the age of 55 smoked compared with 23.9% of those under 55 years of age. Rates of smoking cessation did not differ for those older than 55 years (25.1%) and younger patients (26.1%). Current smokers in both age-groups reported greater pain than those who had never smoked in all pain ratings (P < .001). Mean improvement in reported pain over the course of treatment was significantly different in nonsmokers and current smokers in both age-groups (P < .001). Those who quit smoking during the course of care reported greater improvement in pain than those who continued to smoke. The mean improvement in pain ratings was clinically significant in patients in all 3 groups of nonsmokers whereas those who continued to smoke had no clinically significant improvement in reported pain. Conclusion: The results support the need for smoking cessation programs, given a strong association between improved patient-reported pain and smoking cessation. Fewer older patients smoke but they are equally likely to quit.

Abstract
Introduction Cigarette smoking is common among adults with chronic pain. The primary objective of this study was to determine the period prevalence of smoking in patients with chronic pain. A secondary objective was to determine the prevalence of smoking among patients with commonly occurring pain diagnoses including fibromyalgia, low back pain, and headache. Methods This population study included 5350 patients (1256 smokers, 4094 nonsmokers) admitted to the Mayo Comprehensive Pain Rehabilitation Center from January 1998 through December 2012. Smoking status was determined using a self-report questionnaire. Results During the 15 year study period, the overall prevalence of smoking was 23.5 % (95 % CI 22.4 – 24.6). The prevalence of smoking in 2000, 2005, and 2010 was 24.2, 25.7, and 28.3 % respectively. The overall prevalence of smoking in patients with fibromyalgia, low back pain, and headache was 25.2 % (95 % CI 22.8 – 28.3), 22.8 % (95 % CI 21.3 – 25.9), and 21.2 % (95 % CI 17.9 – 24.7), respectively. In a multiple variable logistic model adjusted for age and sex, opioid use was significantly associated with status as a current smoker. Conclusion The prevalence of smoking in patients with chronic pain has not declined when compared to the general population. The higher prevalence of smoking was consistently observed in commonly occurring pain diagnoses including fibromyalgia, back pain, and headache. Further research is needed to identify the potential factors that contribute to the high prevalence of smoking in this patient population.

Abstract
Background Many human and animal studies have shown the influence of nicotine and caffeine on pain perception and processing. This study aims to investigate whether smoking or caffeine consumption influences trigeminal pain processing. Methods Sixty healthy subjects were investigated using simultaneous recordings of the nociceptive blink reflex (nBR) and pain related evoked potentials (PREP) following nociceptive electrical stimulation on both sides of the forehead (V1). Thirty subjects were investigated before and after smoking a cigarette, as well as before and after taking a tablet of 400 mg caffeine. Results After smoking PREP showed decreased N2 and P2 latencies indicating central facilitation at supraspinal (thalamic or cortical) level. PREP amplitudes were not changed. NBR showed a decreased area under the curve (AUC) indicating central inhibition at brainstem level. After caffeine intake no significant changes were observed comparing nBR and PREP results before consumption. Conclusions Smoking influences trigeminal pain processing on supraspinal and brainstem level. In the investigated setting, caffeine consumption does not significantly alter trigeminal pain processing. This observation might help in the further understanding of the pathophysiology of pain disorders that are associated with excessive smoking habits such as cluster headache. Previous smoking has to be taken into account when performing electrophysiological studies to avoid bias of study results.

Abstract
The relationship between behavior (eg, diet, exercise, substance use) and the functioning of chronic-pain patients, including orofacial-pain patients, is poorly understood. This preliminary study examined cigarette smoking and both pain-related and psychological functioning in female orofacial-pain patients. Correlates of intentions to quit smoking were also explored. There were 48 participants in this cross-sectional study. Smokers reported significantly less self-control over pain (d = .66), lower general activity levels (d = .52), more fatigue (d = .80), and poorer sleep quality (d = .53) than non-smokers. The mean effect size for all dependent variables was .49 (range, .33-.80) with the smallest and largest effect found for negative mood and fatigue, respectively. More positive attitudes toward smoking cessation independently predicted stronger intentions to quit (β = .52, p = .03). Findings suggest smoking is significantly associated with pain-related and psychological functioning in female orofacial-pain patients. Smoking-cessation treatment for these patients should include motivational interviewing techniques directed toward attitudinal change.

Abstract
Chronic rheumatic conditions are typically characterized by chronic pain and are uniquely associated with increased rates of cigarette smoking and poor sleep quality. However, no study has examined the possible additive or interactive effects of these two health behaviors in individuals diagnosed with a chronic rheumatic condition. The goal of this study is to examine the relationship between cigarette smoking and sleep in a population sample of individuals diagnosed with a chronic rheumatic condition and related functional impairment. Cross sectional survey data was obtained from the 2007 National Health Interview Survey. Individuals diagnosed with a chronic rheumatic condition were more likely to be a former or current smoker compared to non-diagnosed individuals. Individuals with a chronic rheumatic condition were more likely to report <6 h of sleep per night and endorsed significantly more insomnia and daytime sleepiness. There was no interaction between diagnosis of a chronic rheumatic condition and smoking status on any of the sleep outcomes assessed. Finally, an interaction was observed suggesting individuals with a chronic rheumatic condition who currently smoke are more likely to report averaging <6 h of sleep per night and frequent insomnia compared to individuals with a chronic rheumatic condition who never smoked. These results suggest both a unique and additive relationship between smoking and sleep in individuals with a chronic rheumatic condition. Findings can likely be generalized to other conditions commonly associated with chronic pain.

Abstract
STUDY DESIGN Single-site, exploratory, cross-sectional design. OBJECTIVE To identify variables associated with disability related to low back pain (LBP), as measured by the modified Oswestry Low Back Pain Disability Questionnaire (mOSW), in a sample of working adults with nonacute LBP. BACKGROUND Compared to acute LBP, there is little information available in the literature to identify variables associated with LBP-related disability in working individuals with stage 2 and stage 3 LBP. METHODS Data analyzed were from working individuals with nonacute LBP (n = 235). The response variable was dichotomized by mOSW score (less than 20 or 20 or greater), and the regressor variables included 27 self-report, sociodemographic, impairment-based, and kinematic measures used to assess individuals with LBP. Logistic regression was used to identify variables associated with mOSW. RESULTS One hundred eleven subjects had a mOSW score of 20 or greater, and 124 subjects had a mOSW score of less than 20. Logistic regression analysis identified 4 variables associated with LBP-related disability (mOSW): duration of LBP (P = .006), numeric pain rating (P<.0001), Fear-Avoidance Beliefs Questionnaire physical activity subscale (P = .0007), and limits of stability movement velocity in the forward direction (P = .02). The best model had an R2(u) of 0.25. CONCLUSION The odds of LBP-related disability (mOSW) in this sample of nonacute working individuals were found to increase with longer duration of LBP, higher numeric pain rating scores, higher Fear-Avoidance Beliefs Questionnaire physical activity subscale scores, and slower limits of stability movement velocity in the forward direction. The identification of limits of stability movement velocity is a novel finding that may support a link between sensorimotor balance deficits and disability in working individuals with nonacute LBP.

Abstract
BACKGROUND Smoking is associated with low back pain, intervertebral disc disease, inferior patient outcomes following surgical interventions, and increased rates of postoperative complications. The purpose of the present study was to examine the effect of smoking and smoking cessation on pain and disability in patients with painful spinal disorders. METHODS We examined a prospectively maintained database of records for 5333 patients with axial or radicular pain from a spinal disorder with regard to smoking history and the patient assessment of pain on four visual analog scales during the course of care. Confounding factors, including secondary gain, sex, age, and body mass index, were also examined. The mean duration of follow-up was eight months. Multivariate statistical analysis was performed with variables including smoking status, secondary gain status, sex, depression, and age as predictors of pain and disability. RESULTS Compared with patients who had never smoked, patients who were current smokers reported significantly greater pain in all visual analog scale pain ratings (p < 0.001). The mean improvement in reported pain over the course of care was significantly different between nonsmokers and current smokers (p <0.001). Compared with patients who had continued to smoke, those who had quit smoking during the course of care reported significantly greater improvement in pain in visual analog scale pain ratings for worst (p = 0.013), current (p < 0.05), and average weekly pain (p = 0.024). The mean improvement in the visual analog scale pain ratings was clinically important in patients in all three groups of nonsmokers. As a group, those who had continued smoking during treatment had no clinically important improvement in reported pain. CONCLUSIONS Given a strong association between improved patient-reported pain and smoking cessation, this study supports the need for smoking cessation programs for patients with a painful spinal disorder.

Abstract
Tobacco addiction and chronic pain represent 2 highly prevalent and comorbid conditions that engender substantial burdens upon individuals and systems. Interrelations between pain and smoking have been of clinical and empirical interest for decades, and research in this area has increased dramatically over the past 5 years. We conceptualize the interaction of pain and smoking as a prototypical example of the biopsychosocial model. Accordingly, we extrapolated from behavioral, cognitive, affective, biomedical, and social perspectives to propose causal mechanisms that may contribute to the observed comorbidity between these 2 conditions. The extant literature was 1st dichotomized into investigations of either effects of smoking on pain or effects of pain on smoking. We then integrated these findings to present a reciprocal model of pain and smoking that is hypothesized to interact in the manner of a positive feedback loop, resulting in greater pain and increased smoking. Finally, we proposed directions for future research and discussed clinical implications for smokers with comorbid pain disorders. We observed modest evidence that smoking may be a risk factor in the multifactorial etiology of some chronically painful conditions and that pain may come to serve as a potent motivator of smoking. We also found that whereas animal studies yielded consistent support for direct pain-inhibitory effects of nicotine and tobacco, results from human studies were much less consistent. Future research in the emerging area of pain and smoking has the potential to inform theoretical and clinical applications with respect to tobacco smoking, chronic pain, and their comorbid presentation.

Abstract
UNLABELLED Smoking cigarettes is prevalent among individuals with chronic pain. Some studies indicate nicotine reduces pain and others suggest it may cause or exacerbate pain. Participants in this cross-sectional study were 151 chronic pain patients from a large, urban VA medical center. Patients were divided into 3 groups: 1) nonsmokers; 2) smokers who deny using cigarettes to cope with pain; and 3) smokers who report using cigarettes to cope with pain. Patients who reported smoking as a coping strategy for chronic pain scored significantly worse compared with the other 2 groups on the majority of measures of pain-related outcome. Nonsmokers and smokers who denied smoking to cope did not differ on any variable examined. After controlling for the effects of demographic and clinical factors, smoking cigarettes as a coping strategy for pain was significantly and positively associated with pain intensity (P = .04), pain interference (P = .005), and fear of pain (P = .04). In addition to assessing general smoking status, a more specific assessment of the chronic pain patient's reasons for smoking may be an important consideration as part of interdisciplinary pain treatment. PERSPECTIVE This paper describes the relationship between smoking cigarettes as a mechanism to cope with chronic pain and pain-related outcome. Understanding this relationship may illuminate the broader relationship between smoking and chronic pain and provide new directions for effective interdisciplinary pain treatment.

Abstract
INTRODUCTION Smokers are at increased risk of developing chronic pain and suffering higher pain intensity. However, nicotine has analgesic properties, and smokers may view smoking as a means to cope with pain. Smoking cessation is clearly beneficial to the long-term health of smokers. However, it is not known how abstinence from smoking affects pain. The aim of this study was to determine the association between smoking cessation and changes in pain symptoms by secondary analysis of a large longitudinal dataset of older adults. METHODS Secondary analyses were performed of longitudinal biennial survey data (1992 through 2006) from the nationally representative Health and Retirement Study of United States adults older than 50 years. Multivariate logistic regressions were utilized to determine the relationship between the changes in smoking status and changes in pain symptoms, controlling for demographics, depression, self-rated health, history of arthritis, and body mass index. RESULTS In multivariate analyses, among the 4,695 smokers who reported no pain or mild pain at enrollment, smoking status was not independently associated with exacerbation of pain (odds ratio [OR]: 0.95, 95% CI: 0.84, 1.08). Among the 1,118 smokers who reported moderate to severe pain at enrollment, smoking status was not independently associated with improvement of pain (OR: 0.87, 95% CI: 0.70, 1.08). CONCLUSIONS Smoking cessation was not independently associated with changes in pain symptoms in older adults. These results suggest that concerns regarding the effects of abstinence from smoking on pain should not pose a barrier to offering tobacco use interventions to smokers with chronic pain.

Abstract
Background: Lower back pain (LBP) is one of the primary causes of disability in the Canadian community. However, only a limited number of studies have addressed the association between daily smoking and LBP in Canada. Of the studies that have explored this association, many had small sample sizes and failed to control for confounders. Objective: The primary objective of the study was to determine if daily smoking is associated with an increased risk of having LBP. The secondary objectives were to assess the risk for LBP among occasional smokers and to determine the prevalence of LBP in relation to different covariates. Data and study design: Using the Canadian Community Health Survey (cycle 3.1) data, 73,507 Canadians between the ages of 20 and 59 years were identified. LBP status, smoking level, sex, age, body mass index (BMI), level of activity and level of education were assessed in these subjects. Methods: Stratified analysis and logistic regression analysis were used to detect effect modifications and to adjust for covariates. Population weight and design were taken into consideration. Results: The prevalence of LBP was 23.3% among daily smokers and 15.7% among non-smokers. Age and sex were found to be effect modifiers. The association between LBP and daily smoking was statistically significant in all ages and genders; this association was stronger for younger age groups. The adjusted odds ratio for male daily smokers aged 20 to 29 was 1.87 (95% CI = 1.62, 2.17); findings were similar for women. Occasional smoking slightly increased the odds of having back pain. Conclusion: Young Canadian daily smokers are at higher risk for LBP. This study also suggests a positive correlation between smoking dose and the risk of LBP. These findings indicate that smoking behavioral modification may have an impact on reducing back pain especially among young adults.

Abstract
STUDY DESIGN A literature-based review. OBJECTIVE To summarize the clinical and morphologic findings leading to diagnosis, the etiologic factors, and principles of management. To identify the strengths and limits of past studies. SUMMARY OF BACKGROUND DATA There are considerable controversies regarding etiologic factors, diagnosis, and management of adjacent segment disease in patients instrumented for idiopathic scoliosis. METHODS Summarized is past literature and, to some extent, personal experience of the authors. RESULTS Several factors participating to this complex pathophysiology are reported. The clinical presentation, occurring after symptom free interval, can vary, and modern morphologic investigations help for diagnosis. Management is often surgical and remains challenging. CONCLUSIONS Long-term consequences of spinal fusions are now major concerns, especially in young patients undergoing surgical correction for idiopathic scoliosis. Adjacent segment disease is defined by a combination of clinical symptoms and morphologic findings. Several etiologic factors have been reported, but need to be further studied to prevent and improve the surgical management of this complication.

Abstract
INTRODUCTION There is a sizeable and growing body of empirical literature on the effects of physician advice to quit smoking. Because of the association between tobacco use and the health problems that may provoke referral to chiropractic care, doctors of chiropractic (DCs) may be able to give patients personalized proximal health feedback that may motivate them to quit. However, DCs have not been utilized in this role. The primary aim of this study was to design and refine a brief office-based tobacco intervention for use within chiropractic settings. METHODS This study was conducted in 20 private chiropractic practices in 2 phases: (a) intervention development, in which we created and focus tested practitioner and patient materials, and (b) feasibility, in which we evaluated the impact of the intervention on 210 tobacco-using chiropractic patients. RESULTS Analyses were conducted on 156 patients who exclusively smoked cigarettes. Using an intent-to-treat approach, assuming all nonresponders to be smokers, 13 (8.3%) reported 7-day abstinence at 6 weeks, 22 (14.1%) at the 6-month follow-up, and 35 (22.4%) at the 12-month assessment. Eleven participants (7.1%) reported prolonged abstinence at the 6-month follow-up, and 15 (9.6%) reported prolonged abstinence at 12 months. CONCLUSIONS To our knowledge, this is the first study to refine a brief office-based treatment for tobacco dependence for use in chiropractic settings. The results of this study were promising and will lead to a randomized clinical trial. If found to be effective, this model could be disseminated to chiropractic practitioners throughout the United States.

Abstract
BACKGROUND Low back pain (LBP) is by far the most prevalent and costly musculoskeletal problem in our society today. Following the recommendations of the Multinational Musculoskeletal Inception Cohort Study (MMICS) Statement, our study aims to define outcome assessment tools for patients with acute LBP and the time point at which chronic LBP becomes manifest and to identify patient characteristics which increase the risk of chronicity. METHODS Patients with acute LBP will be recruited from clinics of general practitioners (GPs) in New Zealand (NZ) and Switzerland (CH). They will be assessed by postal survey at baseline and at 3, 6, 12 weeks and 6 months follow-up. Primary outcome will be disability as measured by the Oswestry Disability Index (ODI); key secondary endpoints will be general health as measured by the acute SF-12 and pain as measured on the Visual Analogue Scale (VAS). A subgroup analysis of different assessment instruments and baseline characteristics will be performed using multiple linear regression models. This study aims to examine: 1. Which biomedical, psychological, social, and occupational outcome assessment tools are identifiers for the transition from acute to chronic LBP and at which time point this transition becomes manifest. 2. Which psychosocial and occupational baseline characteristics like work status and period of work absenteeism influence the course from acute to chronic LBP. 3. Differences in outcome assessment tools and baseline characteristics of patients in NZ compared with CH. DISCUSSION This study will develop a screening tool for patients with acute LBP to be used in GP clinics to access the risk of developing chronic LBP. In addition, biomedical, psychological, social, and occupational patient characteristics which influence the course from acute to chronic LBP will be identified. Furthermore, an appropriate time point for follow-ups will be given to detect this transition. The generalizability of our findings will be enhanced by the international perspective of this study.

Abstract
Tobacco smoking has been associated with the development and exacerbation of chronically painful conditions. Conversely, there is reason to believe that smokers may be motivated to use tobacco as a means of coping with their pain. To date, no controlled, experimental studies have tested for a causal relationship between pain and smoking motivation. The primary aim of the current study was to test the hypothesis that laboratory-induced cold pressor pain would enhance smoking motivation, as measured by self-reported urge to smoke and observation of immediate smoking behavior. Smokers (N=132) were randomly assigned to either pain or no pain conditions. Results indicated that situational pain increased urge ratings and produced shorter latencies to smoke. The relationship between pain and increased urge to smoke was partially mediated by pain-induced negative affect. The relationship between pain and shorter latency to smoke was fully mediated by pain-induced urge to smoke. This study provides the 1st experimental evidence that situational pain can be a potent motivator of smoking.

Abstract
STUDY DESIGN Randomized controlled trial. OBJECTIVE To assess the effects of a lifestyle intervention for hypertension on low back pain. SUMMARY OF BACKGROUND DATA According to prospective etiologic studies, a causal association exists between certain lifestyle factors and low back pain. These factors are similar to those that elevate the risk for hypertension. Nevertheless, no randomized controlled trial has assessed effectiveness of lifestyle intervention for the treatment of hypertension on the prevalence of low back pain. METHODS A total of 731 hypertensive employees from 45 worksites were assigned to multidisciplinary lifestyle interventions for hypertension in a rehabilitation center or to routine care in occupational or primary healthcare services during 12 months. Questionnaire data on low back pain were used to assess the effects of the intervention on the extent of low back pain and disability. RESULTS The changes in prevalence and duration of low back pain, and related disability did not differ between the 2 groups, although there were favorable changes in some risk factors, such as body weight and physical inactivity. Subgroup analyses among patients with moderately heavy or heavy work showed that the prevalence of low back pain during the previous 12 months decreased more in the intervention than in the control group. CONCLUSION Multidisciplinary lifestyle intervention aimed to reduce hypertension is not effective at reducing prevalence of low back pain or disability. However, in the subgroup of persons doing moderate or heavy work, the intervention seemed to reduce prevalence of low back pain during the 1-year follow-up.

Abstract
This chapter reviews the impact of chronic musculoskeletal pain on patients' health-related quality of life. In addition to the physical health consequences, chronic musculoskeletal pain can have a profound negative impact on an individual's emotional and social well-being. Although efforts in the health sector are obviously of crucial importance in the management of chronic musculoskeletal pain, a high level of patient and societal involvement is key to reducing the burden of this condition. Patients should work in partnership with health-care professionals, actively participating in their care. Family members should encourage their loved ones to be as independent as possible. The employer of a person with chronic musculoskeletal pain has a vital role in returning him or her to work as soon as possible. Removing all barriers to the use of preventive and therapeutic services will help us to reduce the burden of musculoskeletal pain conditions on both patients and society.

Abstract
Background The chiropractic profession has long considered itself to be a preventive science. Recently the Council on Chiropractic Education (CCE) has defined a set of standards that must be implemented at all US chiropractic colleges as of January of 2007. These are specific to wellness measures and health promoting efforts that should be performed by chiropractors. This will mandate traditional health promotion and prevention methods be taught to students at accredited colleges and to practicing chiropractors. Objective To present the idea of performing traditional health promotion and wellness-concepts in chiropractic practice as a call to action for clinicians and generate discussion on the topic. Discussion This manuscript discusses relevant topics of health promotion and prevention for chiropractors and other practicing clinicians that should be made priorities with patients in order to enhance both patient health and community and population health. Conclusion All practicing chiropractors, as well as other clinicians should take these new standards from the CCE as a call to action to begin helping patients address the removable causes of morbidity, disability and premature mortality where they exist, in addition to treating their painful spinal conditions.

Abstract
BACKGROUND Tobacco use, particularly smoking, is the most preventable cause of death in the United States. More than 400,000 premature deaths are associated with its use and the health care costs are in the billions. All health care provider groups should be concerned with patients who continue to smoke and use tobacco. The US Preventive Services Taskforce and Health People 2010 guidelines encourage providers to counsel smokers on cessation. Current studies, though limited regarding chiropractic advising practices indicate a low engagement rate when it comes to providing cessation information. OBJECTIVE To test a campaign regarding initial impact aimed at increasing chiropractic interns advising on cessation and delivery of information to smokers on cessation. DISCUSSION Chiropractic interns do engage patients on smoking status and can be encouraged to provide more cessation messages and information to patients. The initial impact assessment of this campaign increased the provision of information to patients by about 25%. The prevalence of smoking among chiropractic patients, particularly at teaching clinics may be lower than the national averages. CONCLUSION Chiropractic interns can and should be encouraged to advise smokers about cessation. A systematic method of intake information on smoking status is needed and a standardized education protocol for chiropractic colleges is needed. Chiropractic colleges should assess the adequacy of their advising roles and implement changes to increase cessation messages to their patients as soon as possible.

Negrini S, Grivas TB, Kotwicki T, Maruyama T, Rigo M, Weiss HR. Why do we treat adolescent idiopathic scoliosis? What we want to obtain and to avoid for our patients. SOSORT 2005 Consensus paper. SCOLIOSIS 2006; 1:4. [PMID: 16759352 PMCID: PMC1475888 DOI: 10.1186/1748-7161-1-4] [Citation(s) in RCA: 126] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/14/2005] [Accepted: 04/10/2006] [Indexed: 01/03/2023]
Abstract
Background Medicine is a scientific art: once science is not clear, choices are made according to individual and collective beliefs that should be better understood. This is particularly true in a field like adolescent idiopathic scoliosis, where currently does not exist definitive scientific evidence on the efficacy either of conservative or of surgical treatments. Aim of the study To verify the philosophical choices on the final outcome of a group of people believing and engaged in a conservative treatment of idiopathic scoliosis. Methods We performed a multifaceted study that included a bibliometric analysis, a questionnaire, and a careful Consensus reaching procedure between experts in the conservative treatment of scoliosis (SOSORT members). Results The Consensus reaching procedure has shown to be useful: answers changed in a statistically significant way, and 9 new outcome criteria were included. The most important final outcomes were considered Aesthetics (100%), Quality of life and Disability (more than 90%), while more than 80% of preferences went to Back Pain, Psychological well-being, Progression in adulthood, Breathing function, Scoliosis Cobb degrees (radiographic lateral flexion), Needs of further treatments in adulthood. Discussion In the literature prevail outcome criteria driven by the contingent treatment needs or the possibility to have measurement systems (even if it seems that usual clinical and radiographic methods are given much more importance than more complex Disability or Quality of Life instruments). SOSORT members give importance to a wide range of outcome criteria, in which clinical and radiographic issues have the lowest importance. Conclusion We treat our patients for what they need for their future (Breathing function, Needs of further treatments in adulthood, Progression in adulthood), and their present too (Aesthetics, Disability, Quality of life). Technical matters, such as rib hump or radiographic lateral alignment and rotation, but not lateral flexion, are secondary outcomes and only instrumental to previously reported primary outcomes. We advocate a multidimensional, comprehensive evaluation of scoliosis patients, to gather all necessary data for a complete therapeutic approach, that goes beyond x-rays to reach the person and the family.

Abstract
BACKGROUND The materials handling industry performs is an essential function in the world economy, however, it is plagued with occupationally related injuries and illnesses. Understanding the risk factors may assist this industry in alleviating these injuries and illnesses, as well as their associated costs. METHODS Forty-eight personal and non-occupational risk factors were measured and evaluated for statistically significant relationships with occupational injury in 442 volunteer manual material handlers who worked for three different companies, at nine US locations, with 15 different job descriptions. OSHA 200 logs were used to ascertain evidence of occupational injury within this population for 1 year after the testing and measurement was completed. RESULTS Higher occurrences of injury were significantly associated with six risk factors in the univariate model (odds ratios 1.51-4.00). The significantly (P < 0.05) related risk factors in the univariate model were aerobic power, smoking status, perceived fitness level, fishing/hunting as a hobby, speed limit obeyance, and witnessing or being involved in a violent fight. In the multivariate analysis, five risk factors (aerobic power, smoking status, percent body fat, body mass index, and sit-and-reach measured flexibility) were significantly (P < 0.05) associated with occupational injury. Odds ratios in the multivariate analysis varied from 1.42 to 10.11. CONCLUSION Evidence of an association of occupational injury occurrence with certain risk factors presented in personal and non-occupational univariate and multivariate models is shown. In industry, effective injury reduction programs should go beyond traditional methods of job-related ergonomic risk factors and include personal factors such as smoking, weight control, and alcohol abuse.

CHIROPRACTIC & OSTEOPATHY 2005; 13:25.

Abstract
BACKGROUND Screening for adolescent idiopathic scoliosis (AIS) is a commonly performed procedure for school children during the high risk years. The PRECEDE-PROCEDE (PP) model is a health promotion planning model that has not been utilized for the clinical diagnosis of AIS. The purpose of this research is to study AIS in the school age population using the PP model and its relevance for community, school, and clinical health promotion. METHODS MEDLINE was utilized to locate AIS data. Studies were screened for relevance and applicability under the auspices of the PP model. Where data was unavailable, expert opinion was utilized based on consensus. RESULTS The social assessment of quality of life is limited with few studies approaching the long-term effects of AIS. Epidemiologically, AIS is the most common form of scoliosis and leading orthopedic problem in children. Behavioral/environmental studies focus on discovering etiologic relationships yet this data is confounded because AIS is not a behavioral. Illness and parenting health behaviors can be appreciated. The educational diagnosis is confounded because AIS is an orthopedic disorder and not behavioral. The administration/policy diagnosis is hindered in that scoliosis screening programs are not considered cost-effective. Policies are determined in some schools because 26 states mandate school scoliosis screening. There exists potential error with the Adam's test. The most widely used measure in the PP model, the Health Belief Model, has not been utilized in any AIS research. CONCLUSION The PP model is a useful tool for a comprehensive study of a particular health concern. This research showed where gaps in AIS research exist suggesting that there may be problems to the implementation of school screening. Until research disparities are filled, implementation of AIS screening by school, community, and clinical health promotion will be compromised. Lack of data and perceived importance by school/community health planners may influence clinical health promotion practices.
