Abstract
OBJECTIVE Self-injurious behavior (SIB) is a significant public health concern in the United States, especially among adolescents with histories of maltreatment. This study compared maltreatment characteristics and reasons for SIB between three homogenous samples of adolescents with either: (1) non-suicidal self-injury (NSSI); (2) suicide attempt/s (SA), and (3) typically developing controls (TDC). METHOD Participants (N = 124) aged 13-17 years completed questionnaires about their maltreatment and SIB histories. RESULTS Maltreatment rates were as follows: 90% NSSI group, 76% SA group, and 40% TDC group. Adolescents in the NSSI group reported significantly higher rates of emotional neglect compared to the SA group. Maltreated adolescents in the NSSI and SA groups reported the same top three SIB reasons: (1) get rid of bad feelings, (2) mental state at the time, and (3) problems with family. However, maltreated NSSI participants were significantly more likely to engage in SIB for emotion regulation reasons than maltreated SA participants, who were more likely to engage in SIB for interpersonal reasons. Physical neglect and physical abuse also arose as significant predictors of specific SIB reasons. CONCLUSIONS Our findings help elucidate the maltreatment profiles and reasons for SIB among adolescents engaged in NSSI or SA. Specific maltreatment experiences may also influence the reasons why adolescents engaged in SIB.

Abstract
Around 40% of preterm births are attributed to ascending intrauterine infection, and Ureaplasma parvum (UP) is commonly isolated in these cases. Here we present a mouse model of ascending UP infection that resembles human disease, using vaginal inoculation combined with mild cervical injury induced by a common spermicide (Nonoxynol-9, as a surrogate for any mechanism of cervical epithelial damage). We measure bacterial load in a non-invasive manner using a luciferase-expressing UP strain, and post-mortem by qPCR and bacterial titration. Cervical exposure to Nonoxynol-9, 24 h pre-inoculation, facilitates intrauterine UP infection, upregulates pro-inflammatory cytokines, and increases preterm birth rates from 13 to 28%. Our results highlight the crucial role of the cervical epithelium as a barrier against ascending infection. In addition, we expect the mouse model will facilitate further research on the potential links between UP infection and preterm birth.

Abstract
Preterm birth, defined as delivery before 37 weeks of gestation, is the leading cause of neonatal mortality and morbidity. Infection and inflammation are frequent antecedents of spontaneous preterm birth. Cathelicidin, an antimicrobial host defence peptide, is induced by infection and inflammation and although expressed in the reproductive tract and fetal tissues, its role in the pathogenesis of spontaneous preterm birth is unknown. Here we demonstrate that cathelicidin expression is increased at RNA and protein level in the mouse uterus in a model of inflammation-induced labour, where ultrasound guided intrauterine injection of lipopolysaccharide (LPS) at E17 stimulates preterm delivery within 24 hours. Cathelicidin-deficient (Camp−/−) mice are less susceptible to preterm delivery than wild type mice following intrauterine injection of 1 μg of LPS, and this is accompanied by a decrease in circulating IL-6, an inflammatory mediator implicated in the onset of labour. We also show that the proportion of cathelicidin expressing cells in the myometrium is higher in samples obtained from women in labour at term than pre-labour. Together, these data suggest that cathelicidin has roles in mediating pro-inflammatory responses in a murine model of inflammation-induced labour, and in human term labour.

Abstract
There is uncertainty regarding how long the effects of acupuncture treatment persist after a course of treatment. We aimed to determine the trajectory of pain scores over time after acupuncture, using a large individual patient data set from high-quality randomized trials of acupuncture for chronic pain. The available individual patient data set included 29 trials and 17,922 patients. The chronic pain conditions included musculoskeletal pain (low back, neck, and shoulder), osteoarthritis of the knee, and headache/migraine. We used meta-analytic techniques to determine the trajectory of posttreatment pain scores. Data on longer term follow-up were available for 20 trials, including 6376 patients. In trials comparing acupuncture to no acupuncture control (wait-list, usual care, etc), effect sizes diminished by a nonsignificant 0.011 SD per 3 months (95% confidence interval: -0.014 to 0.037, P = 0.4) after treatment ended. The central estimate suggests that approximately 90% of the benefit of acupuncture relative to controls would be sustained at 12 months. For trials comparing acupuncture to sham, we observed a reduction in effect size of 0.025 SD per 3 months (95% confidence interval: 0.000-0.050, P = 0.050), suggesting approximately a 50% diminution at 12 months. The effects of a course of acupuncture treatment for patients with chronic pain do not seem to decrease importantly over 12 months. Patients can generally be reassured that treatment effects persist. Studies of the cost-effectiveness of acupuncture should take our findings into account when considering the time horizon of acupuncture effects. Further research should measure longer term outcomes of acupuncture.

Abstract
Human β-defensin 3 (hBD3) is a cationic antimicrobial peptide with potent bactericidal activity in vitro. HBD3 is produced in response to pathogen challenge and can modulate immune responses. The amplified recognition of self-DNA by human plasmacytoid dendritic cells has been previously reported, but we show here that hBD3 preferentially enhances the response to bacterial DNA in mouse Flt-3 induced dendritic cells (FLDCs) and in human peripheral blood mononuclear cells. We show the effect is mediated through TLR9 and although hBD3 significantly increases the cellular uptake of both E. coli and self-DNA in mouse FLDCs, only the response to bacterial DNA is enhanced. Liposome transfection also increases uptake of bacterial DNA and amplifies the TLR9-dependent response. In contrast to hBD3, lipofection of self-DNA enhances inflammatory signaling, but the response is predominantly TLR9-independent. Together, these data show that hBD3 has a role in the innate immune-mediated response to pathogen DNA, increasing inflammatory signaling and promoting activation of the adaptive immune system via antigen presenting cells including dendritic cells. Therefore, our data identify an additional immunomodulatory role for this copy-number variable defensin, of relevance to host defence against infection and indicate a potential for the inclusion of HBD3 in pathogen DNA-based vaccines.

Abstract
Human β-defensin 3 (hBD3) is a cationic host defence peptide and is part of the innate immune response. HBD3 is present on a highly copy number variable block of six β-defensin genes, and increased copy number is associated with the autoimmune disease psoriasis. It is not known how this increase influences disease development, but psoriasis is a T cell-mediated disease and activation of the innate immune system is required for the initial trigger that leads to the amplification stage. We investigated the effect of hBD3 on the response of primary macrophages to various TLR agonists. HBD3 exacerbated the production of type I Interferon-β in response to the viral ligand mimic polyinosinic:polycytidylic acid (polyI:C) in both human and mouse primary cells, although production of the chemokine CXCL10 was suppressed. Compared to polyI:C alone, mice injected with both hBD3 peptide and polyI:C also showed an enhanced increase in Interferon-β. Mice expressing a transgene encoding hBD3 had elevated basal levels of Interferon-β, and challenge with polyI:C further increased this response. HBD3 peptide increased uptake of polyI:C by macrophages, however the cellular response and localisation of polyI:C in cells treated contemporaneously with hBD3 or cationic liposome differed. Immunohistochemistry showed that hBD3 and polyI:C do not co-localise, but in the presence of hBD3 less polyI:C localises to the early endosome. Using bone marrow derived macrophages from knockout mice we demonstrate that hBD3 suppresses the polyI:C-induced TLR3 response mediated by TICAM1 (TRIF), while exacerbating the cytoplasmic response through MDA5 (IFIH1) and MAVS (IPS1/CARDIF). Thus, hBD3, a highly copy number variable gene in human, influences cellular responses to the viral mimic polyI:C implying that copy number may have a significant phenotypic effect on the response to viral infection and development of autoimmunity in humans. Defensins are classically known as antimicrobial peptides due to their ability to rapidly kill pathogens including bacteria, viruses and fungi. They are produced in the presence of infectious agents at body surfaces exposed to the environment. Increasingly, their functional repertoire is expanding, and they have been shown to modulate the immune system. In humans, there is a block of six β-defensin genes that varies in copy number in the population. Individuals with an increased number of β-defensin genes have an increased likelihood of developing the skin autoimmune disease psoriasis. It is not known how this increase in gene copy number influences development of the disease, and psoriasis is a complex interplay of genomic and environmental factors that trigger disease progression and include exposure to viruses. We examined whether a molecular pattern characteristic of viruses produces an altered immune response in the presence of the defensin human β-defensin 3 (hBD3). We find that hBD3 triggers a larger interferon defence response to this viral mimic by increasing accessibility to a cellular receptor that recognises viral patterns. Interferon is known to be important in autoimmunity and our work may explain why individuals with increased β-defensin number are predisposed to develop psoriasis.

Abstract
OBJECTIVES Given the rising profile of the Alexander Technique in the UK, there is a need for a comprehensive description of its teachers and of those who currently take lessons. In a national survey of Alexander teachers, we set out to address this information gap. DESIGN A cross-sectional survey of 871 UK members of three main Alexander Technique teachers' professional associations was conducted. A questionnaire requested information about their professional background, teaching practice and methods, and about the people who attend lessons and their reasons for seeking help. RESULTS With an overall response rate of 61%, 534 teachers responded; 74% were female with median age of 58 years, 60% had a higher education qualification, and 95% were self-employed, many with additional non-Alexander paid employment. The majority (87%) offered lessons on their own premises or in a privately rented room, and 19% provided home visits; both individual and group lessons were provided. People who took lessons were predominantly female (66%) with a median age of 48 years, and 91% paid for their lessons privately. Nearly two-thirds (62%) began lessons for reasons related to musculoskeletal conditions, including back symptoms, posture, neck pain, and shoulder pain. Other reasons were general (18%, including well-being), performance-related (10%, including voice-, music-, and sport-related), psychological (5%) and neurological (3%). We estimate that Alexander teachers in the UK provide approximately 400,000 lessons per year. CONCLUSIONS This study provides an overview of Alexander Technique teaching in the UK today and data that may be useful when planning future research.

Abstract
β-defensin peptides are a family of antimicrobial peptides present at mucosal surfaces, with the main site of expression under normal conditions in the male reproductive tract. Although they kill microbes in vitro and interact with immune cells, the precise role of these genes in vivo remains uncertain. We show here that homozygous deletion of a cluster of nine β-defensin genes (DefbΔ9) in the mouse results in male sterility. The sperm derived from the mutants have reduced motility and increased fragility. Epididymal sperm isolated from the cauda should require capacitation to induce the acrosome reaction but sperm from the mutants demonstrate precocious capacitation and increased spontaneous acrosome reaction compared to wild-types but have reduced ability to bind the zona pellucida of oocytes. Ultrastructural examination reveals a defect in microtubule structure of the axoneme with increased disintegration in mutant derived sperm present in the epididymis cauda region, but not in caput region or testes. Consistent with premature acrosome reaction, sperm from mutant animals have significantly increased intracellular calcium content. Thus we demonstrate in vivo that β-defensins are essential for successful sperm maturation, and their disruption leads to alteration in intracellular calcium, inappropriate spontaneous acrosome reaction and profound male infertility. β-defensins are small molecules, considered primarily to be antimicrobials and important in the first defence response to invading organisms. They are predominantly produced at surfaces in contact with the outside environment and these include skin, airway and reproductive tract. We show here that when we delete from the mouse a subset of nine β-defensin genes, surprisingly the main consequence is that the male mice are completely infertile. When normal sperm leave the male and enter the female reproductive tract they are triggered to undergo a reaction that alters the membrane properties of the sperm and allows fertilisation. We show here that sperm isolated from the male mice, that no longer make these β-defensins, are prematurely ready to fertilise an egg. It is far too early for this to happen and as a consequence the sperm are severely reduced in their ability to move and have a major defect in the structure of their tail. We provide evidence that the reason this has happened is due to a dysregulation of calcium transport. This work is important for understanding defensin gene function in a living organism and may enable the design of novel contraceptives with additional antibiotic ability.

Abstract
OBJECTIVE To compare the effectiveness of acupuncture with other relevant physical treatments for alleviating pain due to knee osteoarthritis. DESIGN Systematic review with network meta-analysis, to allow comparison of treatments within a coherent framework. Comprehensive searches were undertaken up to January 2013 to identify randomised controlled trials in patients with osteoarthritis of the knee, which reported pain. RESULTS Of 156 eligible studies, 114 trials (covering 22 treatments and 9,709 patients) provided data suitable for analysis. Most trials studied short-term effects and many were classed as being of poor quality with high risk of bias, commonly associated with lack of blinding (which was sometimes impossible to achieve). End of treatment results showed that eight interventions: interferential therapy, acupuncture, TENS, pulsed electrical stimulation, balneotherapy, aerobic exercise, sham acupuncture, and muscle-strengthening exercise produced a statistically significant reduction in pain when compared with standard care. In a sensitivity analysis of satisfactory and good quality studies, most studies were of acupuncture (11 trials) or muscle-strengthening exercise (9 trials); both interventions were statistically significantly better than standard care, with acupuncture being statistically significantly better than muscle-strengthening exercise (standardised mean difference: 0.49, 95% credible interval 0.00-0.98). CONCLUSIONS As a summary of the current available research, the network meta-analysis results indicate that acupuncture can be considered as one of the more effective physical treatments for alleviating osteoarthritis knee pain in the short-term. However, much of the evidence in this area of research is of poor quality, meaning there is uncertainty about the efficacy of many physical treatments.

Abstract
Background There is relatively limited knowledge about the practitioners who provide acupuncture treatment within the UK, what conditions patients consult for and the treatment provided. Objectives To characterise the conditions treated and by whom, to examine characteristics of the treatment and to explore trends over time. Method A cross-sectional survey of the UK acupuncture practitioners was conducted; 800 practitioners were selected by computer-generated randomisation sequences from the four major UK-based professional associations. Data collected on the practitioners included demographic details, association membership, statutorily regulated status, practice setting, style of acupuncture, diagnostic methods and needle response sought. Practitioners recorded details of their 10 most recent patients, including demographic details, primary reason for consulting and lifestyle advice provided. Results 330 practitioners responded comprising doctors (29%) physiotherapists (29%), nurses (15%) and independent acupuncturists (27%): 62% were women with median age of 48 years. The majority (68%) practiced in independent settings and 42% practiced within the National Health Service. Patients most commonly consulted for low back, neck, shoulder and knee pain, as well as headaches and migraine. Treatment for infertility by independent acupuncturists was found to have increased fivefold in 10 years. Conclusion Acupuncture provides a substantial contribution to the healthcare of the UK, with an estimated 4 million sessions provided annually. The primary complaints for which patients consult reflect the growing evidence base on acupuncture for these conditions. These data provide a basis for decision-making regarding policy and practice.

Abstract
β-Defensins are cationic host defense peptides that form an amphipathic structure stabilized by three intramolecular disulfide bonds. They are key players in innate and adaptive immunity and have recently been shown to limit the production of pro-inflammatory cytokines in TLR4-stimulated macrophages. In the present study, we investigate the mechanism underlying the anti-inflammatory effect of human β-defensin 3 (hBD3). We show that the canonical structure of hBD3 is required for this immunosuppressive effect and that hBD3 rapidly associates with and enters macrophages. Examination of the global effect of hBD3 on transcription in TLR4-stimulated macrophages shows that hBD3 inhibits the transcription of pro-inflammatory genes. Among the altered genes there is significant enrichment of groups involved in the positive regulation of NF-κB including components of Toll-like receptor signaling pathways. We confirm these observations by showing corresponding decreases in protein levels of pro-inflammatory cytokines and cell surface molecules. In addition, we show that hBD3 reduces NF-κB signaling in cells transfected with MyD88 or TRIF and that hBD3 inhibits the TLR4 response in both MyD88- and TRIF-deficient macrophages. Taken together these findings suggest that the mechanism of hBD3 anti-inflammatory activity involves specific targeting of TLR signaling pathways resulting in transcriptional repression of pro-inflammatory genes.

Abstract
Background Reactions to treatment are common following acupuncture. Understanding how these reactions are interpreted by patients is largely unexplored. Objective To examine patients’ ratings of the severity and bothersomeness of a range of common treatment reactions, and to assess their impact on willingness to try acupuncture again. Methods Self-reported ratings of the frequency, severity and bothersomeness of treatment reactions from 133 patients in the acupuncture arm of a pragmatic randomised controlled trial of acupuncture for chronic back pain are described and analysed. Results A total of 133 acupuncture patients reported at 3 months reactions that they had experienced at any time during a course of up to 10 acupuncture treatment sessions. They received a total of 1150 treatments, an average of 8.6 sessions per patient. All patients reported treatment reactions, most commonly relaxation (84%, n = 112), which was significantly associated with willingness to try acupuncture again, (χ2 = 7.860, df = 1, p = 0.005). Only 16% (n=21) were unwilling to experience a specific treatment reaction again, and 9% (n = 12) were unwilling to try acupuncture again. The most ‘bothersome’ reaction was a temporary worsening of symptoms (29%, n=38), though this was not associated with an unwillingness to try acupuncture again (χ2 = 0.382, df = 1, p>0.536). Those unwilling to try acupuncture again reported significantly less reduction in their pain at 3 months (mean (SE) SF-36 bodily pain score at 3 months 30.453 (3.598) vs 19.30 (1.128); p=0.003). Conclusion Among this group of patients seeking help for low back pain, the experience of treatment reactions was universal. There was no evidence that the bothersomeness of treatment reactions was associated with patient's willingness to try acupuncture again. The benefit of pain reduction over the course of treatment appeared to outweigh self-rated bothersome reactions to treatment.

Abstract
BACKGROUND Rapid Access Chest Pain Clinics have recently been introduced to assist in the management of primary care patients experiencing suspected cardiac chest pain. OBJECTIVE To study the longer term outcome for patients referred to a Rapid Access Chest Pain Clinic and then given a non-cardiac diagnosis. METHODS The study collected retrospective data from a cohort of all patients attending the Rapid Access Chest Pain Clinic based in the cardiorespiratory Department at the York District Hospital, England. Questionnaires were sent to all patients who attended the Rapid Access Chest Pain Clinic during the previous 14 months and were diagnosed with non-cardiac chest pain. Participants reported on their chest pain, subsequent episodes of primary and secondary care and their beliefs about causation of pain. RESULTS Of the patients referred to the Rapid Access Chest Pain Clinic, 235 (52%) did not have cardiac chest pain. Of these patients, 161 (69%) returned the questionnaire, nearly half of whom reported ongoing chest pain. The mean time since Clinic attendance was approximately 8 months and the median duration of ongoing chest pain was 5.4 months. Women were twice as likely as men to continue to be experiencing pain but did not report more frequent or severe pain on average. More than 50% of the non-cardiac group were not convinced by their negative cardiac diagnosis. CONCLUSION There is an ongoing challenge to support patients with non-cardiac chest pain, including the provision of reassurance that their pain is very unlikely to be caused by their heart.

Abstract
Background Adult-derived bone marrow stem cells are capable of reconstituting the haematopoietic system. However there is ongoing debate in the literature as to whether bone marrow derived cells have the ability to populate other tissues and express tissue specific markers. The airway has been an organ of major interest and was one of the first where this was demonstrated. We have previously demonstrated that the mouse airway can be repopulated by side population bone marrow transplanted cells. Here we investigate the frequency and phenotypic nature of these bone marrow derived cells. Methods Female mice were engrafted with male whole bone marrow or side population (SP) cells and subjected to detergent-induced damage after 3 months. Donor cells were identified by Y chromosome fluorescence in situ hybridisation and their phenotype was assessed by immunohistochemistry on the same sections. Slides were visualised by a combination of widefield and deconvolved microscopy and whole cells were analysed on cytospin preparations. Results The frequencies of engraftment of male cells in the airway of mice that show this (9/10), range from 1.0 – 1.6% with whole marrow and 0.6 – 1.5% with SP cells. Undamaged controls have only between 0.1 and 0.2% male cells in the trachea. By widefield microscopy analysis we find 60.2% (53/88) of male donor derived cells express cytokeratins as a marker of epithelial cells. These results were reinforced using deconvolved microscopy and scored by two independent investigators. In addition cytospin analysis of cells dissociated from the damaged trachea of engrafted mice also reveals donor derived Y chromosome positive cells that are immunopositive for cytokeratin. Using cytokeratin and the universal haematopoietic marker CD45 immunohistochemistry, we find the donor derived cells fall into four phenotypic classes. We do not detect cytokeratin positive cells in whole bone marrow using cytokeratin immunostaining and we do not detect any cytokeratin mRNA in SP or bone marrow samples by RT-PCR. Conclusion The appearance of bone marrow derived cells in the tracheal epithelium is enriched by detergent-induced tissue damage and the majority of these cells express an epithelial marker. The cytokeratin positive donor derived cells in the tracheal epithelium are not present in the injected donor cells and must have acquired this novel phenotype in vivo.

Abstract
OBJECTIVE To evaluate the cost effectiveness of acupuncture in the management of persistent non-specific low back pain. DESIGN Cost effectiveness analysis of a randomised controlled trial. SETTING Three private acupuncture clinics and 18 general practices in York, England. PARTICIPANTS 241 adults aged 18-65 with non-specific low back pain of 4-52 weeks' duration. INTERVENTIONS Ten individualised acupuncture treatments over three months from acupuncturists trained in traditional Chinese medicine (n = 160) or usual care only (n = 81). MAIN OUTCOME MEASURE Incremental cost per quality adjusted life year (QALY) gained over two years. RESULTS Total costs to the United Kingdom's health service during the two year study period were higher on average for the acupuncture group (460 pounds sterling; 673 euros; 859 dollars) than for the usual care group (345 pounds sterling) because of the costs associated with initial treatment. The mean incremental health gain from acupuncture at 12 months was 0.012 QALYs (95% confidence interval -0.033 to 0.058) and at 24 months was 0.027 QALYs (-0.056 to 0.110), leading to a base case estimate of 4241 pounds sterling per QALY gained. This result was robust to sensitivity analysis. The probabilistic sensitivity analysis showed acupuncture to have a more than 90% chance of being cost effective at a pound20 000 cost per QALY threshold. CONCLUSION A short course of traditional acupuncture for persistent non-specific low back pain in primary care confers a modest health benefit for minor extra cost to the NHS compared with usual care. Acupuncture care for low back pain seems to be cost effective in the longer term. TRIAL REGISTRATION ISRCTN80764175 [controlled-trials.com].

Abstract
OBJECTIVE To determine whether a short course of traditional acupuncture improves longer term outcomes for patients with persistent non-specific low back pain in primary care. DESIGN Pragmatic, open, randomised controlled trial. SETTING Three private acupuncture clinics and 18 general practices in York, England. PARTICIPANTS 241 adults aged 18-65 with non-specific low back pain of 4-52 weeks' duration. INTERVENTIONS 10 individualised acupuncture treatments from one of six qualified acupuncturists (160 patients) or usual care only (81 patients). MAIN OUTCOME MEASURES The primary outcome was SF-36 bodily pain, measured at 12 and 24 months. Other outcomes included reported use of analgesics, scores on the Oswestry pain disability index, safety, and patient satisfaction. RESULTS 39 general practitioners referred 289 patients of whom 241 were randomised. At 12 months average SF-36 pain scores increased by 33.2 to 64.0 in the acupuncture group and by 27.9 to 58.3 in the control group. Adjusting for baseline score and for any clustering by acupuncturist, the estimated intervention effect was 5.6 points (95% confidence interval -0.2 to 11.4) at 12 months (n = 213) and 8.0 points (2.8 to 13.2) at 24 months (n = 182). The magnitude of the difference between the groups was about 10%-15% of the final pain score in the control group. Functional disability was not improved. No serious or life threatening events were reported. CONCLUSIONS Weak evidence was found of an effect of acupuncture on persistent non-specific low back pain at 12 months, but stronger evidence of a small benefit at 24 months. Referral to a qualified traditional acupuncturist for a short course of treatment seems safe and acceptable to patients with low back pain. TRIAL REGISTRATION ISRCTN80764175 [controlled-trials.com].

Abstract
OBJECTIVES To test whether patients with persistent non-specific low back pain, when offered access to traditional acupuncture care alongside conventional primary care, gained more long-term relief from pain than those offered conventional care only, for equal or less cost. Safety and acceptability of acupuncture care to patients, and the heterogeneity of outcomes were also tested. DESIGN A pragmatic, two parallel group, randomised controlled trial. Patients in the experimental arm were offered the option of referral to the acupuncture service comprising six acupuncturists. The control group received usual care from their general practitioner (GP). Eligible patients were randomised in a ratio of 2:1 to the offer of acupuncture to allow between-acupuncturist effects to be tested. SETTING Three non-NHS acupuncture clinics, with referrals from 39 GPs working in 16 practices in York, UK. PARTICIPANTS Patients aged 18-65 years with non-specific low back pain of 4-52 weeks' duration, assessed as suitable for primary care management by their general practitioner. INTERVENTIONS The trial protocol allowed up to ten individualised acupuncture treatments per patient. The acupuncturist determined the content and the number of treatments according to patient need. MAIN OUTCOME MEASURES The Short Form 36 (SF-36) Bodily Pain dimension (range 0-100 points), assessed at baseline, and 3, 12 and 24 months. The study was powered to detect a 10-point difference between groups at 12 months post-randomisation. Cost--utility analysis was conducted at 24 months using the EuroQoL 5 Dimensions (EQ-5D) and a preference-based single index measure derived from the SF-36 (SF-6D). Secondary outcomes included the McGill Present Pain Index (PPI), Oswestry Pain Disability Index (ODI), all other SF-36 dimensions, medication use, pain-free months in the past year, worry about back pain, satisfaction with care received, and safety and acceptability of acupuncture care. RESULTS A total of 159 patients were in the 'acupuncture offer' arm and 80 in the 'usual care' arm. All 159 patients randomised to the offer of acupuncture care chose to receive acupuncture treatment, and received an average of eight acupuncture treatments within the trial. Analysis of covariance, adjusting for baseline score, found an intervention effect of 5.6 points on the SF-36 Pain dimension [95% confidence interval (CI) -1.3 to 12.5] in favour of the acupuncture group at 12 months, and 8 points (95% CI 0.7 to 15.3) at 24 months. No evidence of heterogeneity of effect was found for the different acupuncturists. Patients receiving acupuncture care did not report any serious or life-threatening events. No significant treatment effect was found for any of the SF-36 dimensions other than Pain, or for the PPI or the ODI. Patients receiving acupuncture care reported a significantly greater reduction in worry about their back pain at 12 and 24 months compared with the usual care group. At 24 months, the acupuncture care group was significantly more likely to report 12 months pain free and less likely to report the use of medication for pain relief. The acupuncture service was found to be cost-effective at 24 months; the estimated cost per quality-adjusted (QALY) was 4241 pounds sterling (95% CI 191 pounds sterling to 28,026 pounds sterling) using the SF-6D scoring algorithm based on responses to the SF-36, and 3598 pounds sterling (95% CI 189 pounds sterling to 22,035 pounds sterling) using the EQ-5D health status instrument. The NHS costs were greater in the acupuncture care group than in the usual care group. However, the additional resource use was less than the costs of the acupuncture treatment itself, suggesting that some usual care resource use was offset. CONCLUSIONS Traditional acupuncture care delivered in a primary care setting was safe and acceptable to patients with non-specific low back pain. Acupuncture care and usual care were both associated with clinically significant improvement at 12- and 24-month follow-up. Acupuncture care was significantly more effective in reducing bodily pain than usual care at 24-month follow-up. No benefits relating to function or disability were identified. GP referral to a service providing traditional acupuncture care offers a cost-effective intervention for reducing low back pain over a 2-year period. Further research is needed to examine many aspects of this treatment including its impact compared with other possible short-term packages of care (such as massage, chiropractic or physiotherapy), various aspects of cost-effectiveness, value to patients and implementation protocols.

Abstract
Camurati-Engelmann disease (CED) is a rare autosomal dominant disorder characterized by bone pain and osteosclerosis affecting the diaphysis of long bones. CED is caused by various missense mutations in the TGFB1 gene that encodes TGFbeta1, the most common of which is an arginine-cysteine amino acid change at codon 218 (R218C) in the latency-associated peptide domain of TGFbeta1. We studied osteoclast formation in vitro from peripheral blood mononuclear cells obtained from three related CED patients harboring the R218C mutation, in comparison with one family-based and several unrelated controls. Osteoclast formation was enhanced approximately 5-fold (P < 0.001) and bone resorption approximately 10-fold (P < 0.001) in CED patients, and the increase in osteoclast formation was inhibited by soluble TGFbeta type II receptor. Total serum TGFbeta1 levels were similar in affected and unaffected subjects, but concentrations of active TGFbeta1 in conditioned medium of osteoclast cultures was higher in the three CED patients than in the unaffected family member. We concluded that the R218C mutation increases TGFbeta1 bioactivity and enhances osteoclast formation in vitro. The activation of osteoclast activity noted here is consistent with clinical reports that have shown biochemical evidence of increased bone resorption as well as bone formation in CED.

Abstract
OBJECTIVE To investigate the attitudes of General Practitioners (GPs) to acupuncture, whether they think it should be available on the NHS and, if so, how it should be provided. DESIGN Attitudinal postal survey. SETTING All 65 practising GPs in the 12 GP practices of the Melton Rutland & Harborough Primary Care Group, UK. RESULTS A response rate of 83% was achieved. The main findings show that 59% of GPs agreed that acupuncture should be available on the NHS, 83% agreed that it can be clinically useful and 72% that it can be cost effective. Among GPs who acknowledged the potential for an increased role for acupuncture on the NHS there was support for the provision of treatment from either medical or non-medical practitioners, delivered at either NHS or non-NHS premises, and with the NHS providing some, or all, of the required funding. CONCLUSION The findings suggest that a majority of GPs are in favour of acupuncture being more widely available on the NHS.

Abstract
Acupuncture treatment and control group interventions in parallel-group randomised trials of acupuncture are not always precisely reported. In an attempt to improve standards, an international group of experienced acupuncturists and researchers devised a set of recommendations, designating them STRICTA: STandards for Reporting Interventions in Controlled Trials of Acupuncture. In a further consensus-building round, the editors of several journals helped redraft the recommendations. These follow the Consolidated Standards for Reporting Trials (CONSORT) format, acting as an extension of the CONSORT guidelines for the specific requirements of acupuncture studies. Participating journals are publishing the STRICTA recommendations and requesting prospective authors to adhere to them when preparing reports for publication. Other journals are invited to adopt these recommendations. The intended outcome is that interventions in controlled trials of acupuncture will be more adequately reported, thereby facilitating an improvement in critical appraisal, analysis and replication of trials.

Abstract
The paper describes the type and frequency of adverse events and transicnt reactions following consultations with professional acupuncturists. In a postal survey, involving 1,848 professional acupuncturists, all of whom were members of the British Acupuncture Council and practising in the UK, details of adverse events and transient reactions following treatment were recorded on standardised self-report forms. A sample size of 30,000 treatments was sought, and piloting indicated that a four-week period was required. Practitioners also provided information on themselves, including age, sex, length of training and years of practice. A total of 574 practitioners responded. 31% of the total population. These practitioners reported on adverse events and transient reactions associated with 34,407 treatments. No serious adverse events were reported, where these were defined as requiring hospital admission, prolonging hospital stays, permanently disabling, or resulting in death (95% CI: 0 to 1.1 per 10,000 treatments). A total of 43 significant minor adverse events were reported, a rate of 1.3 per 1,000 treatments (95% CI: 0.9 to 1.7). These included severe nausea and actual fainting (12), unexpected, severe and prolonged aggravation of symptoms (7), prolonged and unacceptable pain and bruising (5) and psychological and emotional reactions (4). There were three avoidable events: two patients had needles left in by mistake, and one patient had moxa burns to the skin, also caused by practitioner error. The acupuncturists also recorded 10,920 mild transient reactions occurring in 5136 treatments. 15% (95% CI: 14.6 to 15.3) of the 34,407 total. In terms of local reactions, there were reports of mild bruising (1.7%), pain (1.2%) and bleeding (0.4%). Practitioners reported that patients experienced an aggravation of existing symptoms after 2.8% of treatments. The most common mild transient reactions to treatment were feeling relaxed (11.9%) and feeling energised (6.6%). In this prospective survey of 34,407 treatments, practitioners reported no serious adverse events. This conclusion was based on data collected from one in three members of the British Acupuncture Council. Given that the whole membership delivers between one and a half and two million treatments a year, this is important evidence on public health and safety. When compared with medication routinely prescribed in primary care, the results suggest that acupuncture is a relatively safe treatment modality.

Abstract
Patients have the right to be fully informed about the likely benefits and risks of any proposed examination or treatment, and practitioners are obliged to obtain informed consent beforehand. Accurate information about the risks of acupuncture is available following publication of the results of two prospective surveys. At a joint meeting on the safety of acupuncture, members of the three largest UK professional bodies expressed a need to establish what information on risks patients should be given. A standard Information Leaflet was developed by consensus between thesc organisations, and is intended to be used as a stimulus for discussion of standard risks as well as any particular risks that might apply to individual patients. Additionally, it may be used as a form for written consent when this is required. To provide the context for using the Leaflet, the legal and ethical bases of informed consent for medical procedures are discussed.

Abstract
OBJECTIVES To determine patients' experience of outcomes after acupuncture treatment. DESIGN A patient questionnaire followed by semistructured interviews. SETTING Acupuncture practices in York, England. SUBJECTS Questionnaires were distributed by 4 acupuncturists to all 132 of their patients over a 2-week period, 72 (55%) of whom responded. Of these, 11 patients were interviewed. INTERVENTIONS Patients received normal care from their acupuncturists, all of whom were members of the British Acupuncture Council. OUTCOME MEASURES Patients reported on physical symptoms, emotional/mental symptoms, lifestyle changes, major life changes and inner life changes affecting outlook and attitudes to health. Patients also reported on the extent they attributed change to acupuncture and what they valued about attending for treatment. RESULTS Primary reasons for attending were categorized by patients as physical symptoms (90%), mental and emotional problems (9%) and general health and well-being (1%). For physical symptoms, 75% of patients reported definite change; for emotional and mental symptoms, 67%; lifestyle changes, 40%, major life changes, 27%; and for inner life changes, 54%. Over time, many of the patients (42%) changed their primary reason for attending from their initial physical concerns, half of whom describing their new focus as related to general health and well-being. Some emotional changes were experienced by 83% of patients, irrespective of the initial reason for attending. For all these changes, 58% of patients reported that they "substantially" attributed the changes to acupuncture, and 25% "totally". The interviews provided additional data on the depth of the changes particularly for the longer term patients and on what they valued about treatment. CONCLUSIONS Treatment with acupuncture results in a broad range of outcomes from physical and emotional change through to wider benefits involving the patients' lifestyle, outlook, and attitude toward their health. Existing outcome measures are not adequate to assess these wider benefits. The results suggest that patients experienced holistic benefits from acupuncture, an outcome that could be described as holism-in-action.

Abstract
Familial expansile osteolysis (FEO, MIM 174810) is a rare, autosomal dominant bone disorder characterized by focal areas of increased bone remodelling. The osteolytic lesions, which develop usually in the long bones during early adulthood, show increased osteoblast and osteoclast activity. Our previous linkage studies mapped the gene responsible for FEO to an interval of less than 5 cM between D18S64 and D18S51 on chromosome 18q21.2-21.3 in a large Northern Irish family. The gene encoding receptor activator of nuclear factor-kappa B (RANK; ref. 5), TNFRSF11A, maps to this region. RANK is essential in osteoclast formation. We identified two heterozygous insertion mutations in exon 1 of TNFRSF11A in affected members of four families with FEO or familial Paget disease of bone (PDB). One was a duplication of 18 bases and the other a duplication of 27 bases, both of which affected the signal peptide region of the RANK molecule. Expression of recombinant forms of the mutant RANK proteins revealed perturbations in expression levels and lack of normal cleavage of the signal peptide. Both mutations caused an increase in RANK-mediated nuclear factor-kappaB (NF-kappaB) signalling in vitro, consistent with the presence of an activating mutation.

Abstract
This paper presents the research protocol for a pragmatic study of the benefits of providing an acupuncture service to patients in primary care with chronic low back pain. The proposal was written in response to a call for bids from the NHS Executive's centrally funded research programme for Health Technology Assessment (HTA). The research question posed was 'Does acupuncture have long-term effectiveness in the management of pain in primary care?' The present study was designed as a collaboration between an interdisciplinary team drawn from health services researchers at the University of Sheffield, acupuncture researchers from the Foundation for Traditional Chinese Medicine in York, and practitioners from general practice and acupuncture in York. The proposal presented here was submitted in response to an invitation from the Commissioning Board following a successful outline bid. It is reproduced here, largely as submitted in January 1998, using the headings under which information was requested. We also present an appendix describing methodological alterations made to the design in response the Commissioning Board's comments on the proposal. We present it in this format to give an idea of the evolution of the design and the process by which the research proposal was shaped. The final working protocol comprises a combination of these two elements.

Abstract
OBJECTIVES To pilot procedures to be used in a randomized controlled trial of acupuncture for low back pain. DESIGN Uncontrolled clinical trial. SETTING Primary care and acupuncture clinics in York, England. SUBJECTS 20 patients with low back pain lasting 1 month or more. INTERVENTIONS 10 sessions of individualized acupuncture from a traditional acupuncturist. MAIN OUTCOME MEASURES Change in Oswestry low back pain disability questionnaire; present pain intensity scale; effect on daily living scale, and SF-36 general health questionnaire at post-treatment and 6 months after the end of treatment. RESULTS 14 patients completed follow-up. Patients had similar severity scores at baseline to those referred to an NHS outpatient clinic. Post-treatment, there were statistically significant improvements in Oswestry, present pain intensity, effect on daily living and the physical functioning, social functioning, bodily pain, vitality and mental health sub-scales of the SF36. Similar results were found at the six month follow-up. Oswestry scores showed reduced levels of pain at 6 months compared to than at post-treatment, falling approximately 40% from baseline. CONCLUSIONS Though the improvements in pain and quality in life may be due to the natural course of back pain, the promising responses justify further research. The procedures used in the study are appropriate for a randomized controlled trial. Drop-out could be reduced by more careful patient monitoring.

Abstract
Previous studies have shown evidence of constitutive and cytokine-inducible nitric oxide (NO) synthase activity in cultured osteoblast-like cells from various species. Although cytokine-induced NO production has been found to inhibit osteoblast growth, the role of constitutive NO production in regulating osteoblast function is less clear and the isoforms of nitric oxide synthase (NOS) that are expressed by human osteoblasts have not been determined. Here, we investigated NOS expression in cultured human osteoblast-like cells and studied the effects of constitutive and cytokine-induced NO on osteoblast growth and differentiation. Low levels of NO were produced constitutively by osteoblast-like cells as reflected by analysis of medium nitrite concentrations, and evidence of ecNOS mRNA, protein, and bioactivity was found in primary osteoblasts (hOBs), TE85, and MG63 osteosarcoma cells. None of the osteoblast-like cells expressed nNOS, however, and iNOS was produced only by hOB cells after stimulation with the cytokines IL-1beta, TNF-alpha, and IFN-gamma. The NOS inhibitor, L-NMMA, did not affect growth or alkaline phosphatase activity in unstimulated osteoblasts. Incubation of hOB cells with cytokines inhibited growth and stimulated alkaline phosphatase activity and these effects were abrogated by L-NMMA. Cytokines also inhibited growth of TE85 cells and MG63 cells, but these effects appeared to be NO independent because they were not influenced by L-NMMA. Our experiments show that human osteoblasts constitutively produce NO through the ecNOS pathway, but demonstrate that this does not appear to exert an appreciable effect on osteoblast growth or differentiation under basal conditions. In contrast, IL-1beta, TNF-alpha, and IFN-gamma exerted growth-inhibiting and differentiation-inducing effects on osteoblasts that were partly NO dependent, indicating that NO may act predominantly as a modulator of cytokine-induced effects on osteoblast function.

Abstract
In response to recent reviews in the literature that have focused on adverse events due to acupuncture treatment, this article reexamines the original reports from which they derive, particularly the fatalities allegedly caused by acupuncture. The article explores some important issues relating to the debate on risk and safety. Education and research strategies need to be developed so that the acupuncture profession can continue to minimize the likelihood of adverse events occurring in the future.

Abstract
Bone cells, in particular osteocytes, are extremely sensitive to shear stress, a phenomenon that may be related to mechanical adaptation of bone. In this study we examined whether human primary bone cells produce NO in response to fluid shear stress and established by RT/PCR which NOS isoforms were expressed before and after application of shear stress. One hour pulsating fluid flow (PFF; 0.7 +/- 0.02 Pa, 5 Hz) caused a rapid (within 5 min) 2 to 4-fold increase in NO production. NO release was only transiently increased during the first 15 min of exposure to PFF, and remained at control levels during a 1-24 hr postincubation period. In both control and PFF-treated cells, mRNA was easily detected for ecNOS, but not nNOS, and only minimal amounts iNOS were found. mRNA levels for ecNOS increased 2-fold at 1 hr after 1 hr PFF treatment. These results suggest that the rapid production of NO by human bone cells in response to fluid flow results from activation of ecNOS. PFF also leads to an increase in ecNOS mRNA which is likely related to the shear stress responsive element in the promoter of ecNOS.
