    Recent national substance abuse prevention efforts that have been disseminated at the state level have provided fertile ground for addressing the dearth of systematic research on state-level substance abuse prevention infrastructure. The Strategic Prevention Framework State Incentive Grant Program (SPF SIG), a national public health initiative sponsored by the US Substance Abuse and Mental Health Services Administration and its Center for Substance Abuse Prevention, is one such effort, providing an opportunity to examine state-level substance abuse prevention infrastructure across the country. The aims of the SPF SIG initiative include reducing substance abuse and its related problems, as well as enhancing state and local prevention infrastructure and capacity. In this article, we describe the status of state-level substance abuse prevention infrastructure and capacity 1 year after the first 26 funded states ended their projects, based on follow-up interviews with state prevention decision-makers. We found that, in five of the six prevention domains we measured, prevention infrastructure capacity increased during the 12-month period after the grants ended. The evidence for further SPF capacity development even after the conclusion of the grants suggests that states recognized the benefits of using the SPF and took deliberate steps to sustain and enhance the integration of this framework into their state prevention systems. In addition, the findings suggest that state agencies and organizations can benefit from time-limited resources aimed at increasing their capacity and that such efforts can have a lasting impact on measures of state prevention system capacity.

    A novel composite endpoint, sustained pain-free/no adverse events, was recently proposed as a more rigorous means of capturing in a single measure the attributes of migraine pharmacotherapy that patients consider most important: rapid and sustained pain-free response with no side-effects. Using pooled data from two replicate randomized, double-blind, parallel-group, placebo-controlled studies, this post hoc analysis compared the fixed-dose combination tablet sumatriptan/naproxen sodium (n = 726) with sumatriptan monotherapy (n = 723), naproxen sodium monotherapy (n = 720), and placebo (n = 742) with respect to sustained pain-free/no adverse events and closely related composite measures. Sustained pain-free/no adverse events was defined as having both a sustained pain-free response from 2 through 24 hours post-dose with no use of rescue medication and having no adverse events within up to 5 days after dosing with study medication. The percentage of patients with sustained pain-free/no adverse events was 16% with sumatriptan/naproxen sodium compared with 11%, 9% and 7% for sumatriptan, naproxen sodium and placebo, respectively (ppain-free/no adverse events within 1 day; (2) sustained pain-free/no drug-related adverse events within up to 5 days; (3) sustained pain-free/no drug-related adverse events within 1 day; (4) sustained pain relief/no adverse events within up to 5 days; and (5) sustained pain relief/no adverse events within 1 day. The results demonstrate the superiority of sumatriptan/naproxen sodium to sumatriptan monotherapy, naproxen sodium monotherapy and placebo with respect to the rigorous and clinically relevant endpoint of sustained pain-free/no adverse events and reinforce the usefulness of utilizing this new composite endpoint.

    Full Text Available The reduction of forecasts uncertainty is one of the major goal to be achieved in forecasting process. This implies the improvement of predictions accuracy. In this study, many types of forecasts of the annual rate of change for the HICP for EU were developed, their accuracy was evaluated and compared with the accuracy of SPF predictions. All the proposed predictions for January 2010-May 2012 (those based on a random walk developed for 1997-2009, combined forecasts, the median and the mean of forecasts, predictions based on different econometric models that take into account the previous SPF forecasts were not more accurate than the naïve forecasts or SPF ones. A considerably improvement of the accuracy was gotten for predictions based on mean error of SPF expectations for 1997-2009 and the previous registered value. This empirical strategy of building more accurate forecasts was better than the classical theoretical approaches from literature, but it is still less accurate than the naïve forecasts that could be made for UE inflation rate. So, the forecasts based on a simple econometric model as the random walk from the naïve approach are the most accurate, conclusion that is in accordance with the latest researches in literature and with one of the essential condition in forecasting theory.

    The objective of this article is to evaluate, in first attack eletriptan headache and pain-free nonresponders, the efficacy of treating a second and third attack with the same dose of eletriptan 40 mg (ELE-40). Data were pooled from four randomized, double-blind, placebo-controlled, multiple attack studies of eletriptan in the treatment of migraine. The first-attack eletriptan headache (HNR) and pain-free (PFNR) nonresponder samples consisted of patients who did not achieve headache or pain-free responses at two hours, or sustained headache or pain-free responses at 24 hours. The efficacy of the same dose of eletriptan (vs placebo; PBO) in treating the second and third attacks was evaluated using a logistic regression model. Among Attack 1 eletriptan HNRs, treatment with ELE-40 (vs PBO) was associated with significantly higher two-hour headache response and pain-free rates, respectively, on both Attack 2 (48.8% vs 20.2%; 17.0% vs 3.9%; P  pain-free rates at 24 hours were also observed on both Attack 2 and Attack 3. The results of this pooled analysis suggest that patients who have HNR or PFNR to an initial dose of eletriptan may respond when a second and third attack is treated with the same dose.

    Full Text Available Pain control during the dental procedure is essentials and challenging. A complete efficacious pulp anesthesia has not been attained yet. The regional anesthesia such as inferior alveolar nerve block (IANB only does not guarantee the effective anesthesia with patients suffering from irreversible pulpitis. This main aim of this review was to discuss various aspects of intraseptal dental anesthesia and its role significance in pain-free treatment in the dental office. In addition, reasons of failure and limitations of this technique have been highlighted. Literature search was conducted for peer-reviewed articles published in English language in last 30 years. Search words such as dental anesthesia, pain control, intraseptal, and nerve block were entered using a web of knowledge and Google scholar databases. Various dental local anesthesia techniques were reviewed. A combination of block anesthesia, buccal infiltration and intraligamentary injection resulted in deep anesthesia (P = 0.003, and higher success rate compared to IANB. For pain-free management of conditions such as irreversible pulpitis, buccal infiltration (4% articaine, and intraosseous injection (2% lidocaine are better than intraligamentary and IANB injections. Similarly, nerve block is not always effective for pain-free root canal treatment hence, needing supplemental anesthesia. Intraseptal anesthesia is an efficient and effective technique that can be used in maxillary and mandibular adult dentition. This technique is also beneficial when used in conjunction to the regional block or local dental anesthesia.

    Sitting is a common aggravating factor in low back pain (LBP), and re-education of sitting posture is a common aspect of LBP management. However, there is debate regarding what is an optimal sitting posture. This pilot study had 2 aims; to investigate whether pain-free subjects can be reliably positioned in a neutral sitting posture (slight lumbar lordosis and relaxed thorax); and to compare perceptions of neutral sitting posture to habitual sitting posture (HSP). The lower lumbar spine HSP of seventeen pain-free subjects was initially recorded. Subjects then assumed their own subjectively perceived ideal posture (SPIP). Finally, 2 testers independently positioned the subjects into a tester perceived neutral posture (TPNP). The inter-tester reliability of positioning in TPNP was very good (intraclass correlation coefficient (ICC) = 0.91, mean difference = 3% of range of motion). A repeated measures ANOVA revealed that HSP was significantly more flexed than both SPIP and TPNP (p 0.05). HSP was more kyphotic than all other postures. This study suggests that pain-free subjects can be reliably positioned in a neutral lumbar sitting posture. Further investigation into the role of neutral sitting posture in LBP subjects is warranted. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Persistent post-herniotomy pain may be a neuropathic pain state based on the finding of a persistent sensory dysfunction. However, detailed information on the normal distribution of sensory function in pain-free post-herniotomy patients hinders identification of exact pathogenic mechanisms. Therefore, we aimed to establish normative data on sensory function in pain-free patients >1 year after a groin herniotomy. Sensory thresholds were assessed in 40 pain-free patients by a standardized quantitative sensory testing (QST). Secondary endpoints included comparison of sensory function between the operated and the naïve side, and correlation between sensory function modalities. QST showed that on the operated side, thermal data were normally distributed, but mechanical pressure and pinch thresholds were normalized only after log-transformation, and cold pain and pressure tolerance could not be normalized. Comparison of QST results revealed significant (Ppain-free post-herniotomy patients. Future studies of sensory function in persistent post-herniotomy pain should compare the findings to the present data in order to characterize individual patients and potentially identify subgroups, which may aid in allocation of patients to pharmacological or surgical treatment.

    Symptoms of intermittent claudication (IC) can be relieved by lifestyle modification, medications, and walking exercises. The intensity of the walking exercise is still debatable. The goal of this study was to determine the effects of accommodating pain-free walking exercise therapy program length on pain-free walking. A descriptive, longitudinal study with repeated measures of exercise capacity was conducted. An IC questionnaire was administered to assess IC signs, symptoms, and lifestyle. Walking was performed on a treadmill for 30 to 50 minutes below the participant's individualized walking pain threshold. The study included patients diagnosed with IC due to peripheral arterial disease. All participants were randomly assigned to three groups. Group A (n = 28) participated in the walking program for 2-9 weeks, group B (n = 30) for 10-14 weeks, and group C (n = 26) for 15-94 weeks. The main outcome measure of the study was to determine changes in exercise capacity: walking distance (miles), walking duration (minutes), and walking speed (mph). Group A increased the amount of distance, duration, and speed walked from pretest to posttest by 80% (P < .001), 27% (P < .001), and 37% (P < .001), respectively. Group B increased the amount of distance, duration, and speed walked from pretest to posttest by 122% (P < .001), 56% (P < .001), and 43% (P < .001), respectively. Group C increased the amount of distance, duration, and speed walked from pretest to posttest by 26% (P = .002), 22% (P = .002), and 5% (P = .541) respectively. We reached the conclusion that a walking program of 10-14 weeks is optimal for achieving the best improvements in walking distance, duration, and speed.

    Introduction: Achieving successful anesthesia and performing pain-free root canal treatment are important aims in dentistry. This is not always achievable and therefore, practitioners are constantly seeking newer techniques, equipments, and anesthetic solutions for this very purpose. The aim of this review is to introduce strategies to achieve profound anesthesia particularly in difficult cases. Materials and Methods: A review of the literature was performed by electronic and hand searching methods for anesthetic agents, techniques, and equipment. The highest level of evidence based investigations with rigorous methods and materials were selected for discussion. Results: Numerous studies investigated to pain management during root canal treatment; however, there is still no single technique that will predictably provide profound pulp anesthesia. One of the most challenging issues in endodontic practice is achieving a profound anesthesia for teeth with irreversible pulpitis especially in mandibular posterior region. Conclusion: According to most investigations, achieving a successful anesthesia is not always possible with a single technique and practitioners should be aware of all possible alternatives for profound anesthesia.

    Over the last 25 years, pediatric care has changed dramatically with increased survival after premature birth, more complex care, better outcomes, and reduced mortality. There is a better understanding of how pain pathways and receptor systems develop and also how to assess pain at different stages of development. The myth that children do not feel pain has been comprehensively dispelled. Safe analgesic dose regimens for neonates, infants, and children have been developed based upon a better understanding of developmental pharmacokinetics and pharmacodynamics. It is a myth that pain in children cannot be prevented or treated safely and effectively because of the risks of adverse effects and addiction. Large-scale prospective audits have clarified the safety profile and risk-benefit balance for different techniques. There is now a substantial evidence base supporting many techniques of postoperative and procedural pain management for all age-groups of children. Guidelines based upon systematic review of this evidence have been published and updated, but the real challenge is in implementation of accurate pain assessment and safe, effective pain management comprehensively to all children whatever the procedure, clinical setting, developmental stage of the child, or comorbidities. In developed countries, these are core topics in the education of all doctors and nurses who care for children, and they are integrated into clinical practice by acute pediatric pain teams for most hospitals. However, it is disappointing that many country's healthcare systems do not give pediatric pain management a priority and in many parts of the world there are no analgesics available. So pain-free healthcare is sadly lacking in many hospitals. My hope is that the current knowledge can be used more effectively to relieve the unnecessary suffering of children in the 21st century. © 2012 Blackwell Publishing Ltd.

    Adolescents with chronic pain often report inattention and poor memory. There has been little research on cognitive function in this population. The goal of this preliminary pilot study was to examine differences in cognitive function between adolescents with chronic pain to pain-free adolescents. All participants completed baseline assessments of pain, school absences, depression, anxiety, and sleep habits. Standardized neurocognitive tests were used to examine cognitive function with a focus on working memory and attention. Recruitment from the chronic pain clinic resulted in a female sample of 13 individuals (largely reflective of the clinical population). Pain-free age-matched and sex-matched individuals (n=12) were therefore also recruited as controls. Individuals with chronic pain had significantly lower working memory scores than controls. Differences were found between groups on the most difficult selective attention task and not on tests of sustained attention, divided attention, or attentional switching. In a stepwise regression with baseline characteristics entered in the first step, pain accounted for approximately 15% of the variance in working memory and medication score counted for 49% of the variance. This pilot study is the first study to examine differences in working memory and attention between participants with chronic pain and pain-free adolescents. Our findings suggest that chronic pain may negatively affect adolescents' working memory function and highlights the risk for cognitive difficulties and problems with educational progression in addition to negative health and social effects associated with chronic pain. The study provides a starting point for more research and has the potential to direct better identification and treatment of these cognitive deficits.

    Consumers have recently preferred to purchase extensive UV intercepting products, which are waterproof and free from side effects on skin. During the testing of cytotoxicity (in-vitro) in neutral red (NR) method, cell survival ratio of UV-B interceptors decreased to just above 0.08 w/v%, and it was observed that the UV-A interceptors the ratio also decreased to just above 0.06 w/v%. In addition patch-tests of inorganic UV interceptors resulted in no skin irritation even below 10.0 and 11.25. In absorption curves, UV-B was most suitable for octyl methoxycinnamate (OMC) and UV-A for butyl methoxy dibenzoylmethane (BMDM). For this reason, Nylonpoly{sup TM} UVA/UVB the material of OMC and BMDM coated with Nylon and polyethylene, was used as the organic UV interceptor. Zinc oxide (ZnO) and titanium dioxide (TiO{sub 2}) was used as inorganic UV interceptors. The appropriate mixture ratio of ZnO and TiO{sub 2} was 6 to 4:6% of ZnO, 4% of TiO{sub 2} and 5% of Nylonpoly{sup TM} UVA/UVB were all combined and added to our sunscreen cream. The SPF value of in-vitro was 38.9. In practical application, each sun protection factor (SPF) duration of oil-in-water (O/W) emulsion and water-in-silicone (W/S) emulsion containing sunscreen cream of the same content shoed that W/S type of sunscreen cream was 5 times as durable as the other. Therefore, this product is fit for use in swimming, climbing or skiing. This research is to minimize skin trouble caused by UV interceptors and to make one with proper softness, skin safety and UV intercepting efficiency.

    Full Text Available This research focused on the measurement of spectral transmittance using an integrating sphere to estimate the Sun Protection Factor (SPF of commercial sunscreens oriented for child use. Commercially available SPF 30 sunscreens (A, B and C were selected and assessed by the following methodology: pH measurement; rheological profile analysis; and in vitro SPF estimation by spectroscopy. Samples A, B and C exhibited, respectively, pH values of 7.8, 7.4 and 7.0. The rheological profile identified the systems as pseudoplastic nonNewtonian semisolids with hysteresis loops. The t-test (p < 0.05 was used to confront the claimed SPF (SPF = 30 with that estimated by spectroscopy. In vitro tests are considered of utmost importance in the cosmetic field, since their results may be used to validate submission to subsequent in vivo efficacy experiments. According to our results, sunscreens A, B and C generated SPF values without any significant difference from those claimed on the commercial sunscreen labels. The measurement of spectral transmittance with an integrating sphere proved to be a convenient, fast and reproducible method for SPF estimation.

    Past production work has shown that cryogenic tank structure for the Shuttle Booster Rockets and the Titan system have very high life cycle costs for the fuel tank structure. The tanks are machined stiffener-skin combination that are subsequently formed into the required contour after machining. The material scrap rate for these configurations are usually high, and the loss of a tank panel due to forming or heat treatment problems is very costly. The idea of reducing the amount of scrap material and scrapped structural members has prompted the introduction of built-up structure for cryogenic tanks to be explored on the ALS program. A build-up structure approach that has shown improvements in life cycle cost over the conventional built-up approach is the use of superplastically formed (SPF) stiffened panels (reducing the overall part count and weight for the tank) resistance spot welded (RSW) to outer tank skin material. The stiffeners provide for general stability of the tank, while the skin material provides hoop direction continuity for the loads.

    In most individuals suffering from chronic low back pain, psychosocial factors, specifically fear avoidance beliefs (FABs), play central roles in the absence of identifiable organic pathology. On a neurobiological level, encouraging research has shown brain system correlates of somatic and psychological factors during the transition from (sub) acute to chronic low back pain. The characterization of brain imaging signatures in pain-free individuals before any injury will be of high importance regarding the identification of relevant networks for low back pain (LBP) vulnerability. Fear-avoidance beliefs serve as strong predictors of disability and chronification in LBP and current research indicates that back pain related FABs already exist in the general and pain-free population. Therefore, we aimed at investigating possible differential neural functioning between high- and low fear-avoidant individuals in the general population using functional magnetic resonance imaging. Results revealed that pain-free individuals without a history of chronic pain episodes could be differentiated in amygdala activity and connectivity to the pregenual anterior cingulate cortex by their level of back pain related FABs. These results shed new light on brain networks underlying psychological factors that may become relevant for enhanced disability in a future LBP episode.

    Thirty to forty percent of migraineurs do not respond to any given triptan treatment. We identified clinical variables that significantly predict therapeutic non-response and evaluated the efficacy of eletriptan (20, 40 and 80 mg) and sumatriptan (100 mg) vs. placebo in a subgroup of patients with all predictor variables. First-attack data were pooled from 10 randomized, double-blind, placebo-controlled migraine trials (n = 8473). Multivariate regression analyses identified three significant baseline predictors of failure to achieve 2-h pain-free response: severe headache pain, presence of photophobia/phonophobia and presence of nausea. Time of dosing following headache onset did not influence 2-h pain-free response. Among patients with all three risk factors (n = 2010; 24% of total sample), 2-h pain-free response was significantly higher in patients receiving all three doses of eletriptan or sumatriptan vs. placebo (all P < 0.01). Thus, eletriptan and sumatriptan are efficacious in difficult-to-treat patients at high risk for non-response to triptans.

    Most studies have demonstrated that sunscreens with lower sun protection factor (SPF) do not prevent the production of vitamin D because much lower amount of sunscreen (SPFUV radiation can penetrate the skin. Since less sunscreen is applied, higher SPF sunscreens may be used to achieve the desired protection. However, there is little information regarding the application of high-SPF sunscreen and vitamin D formation. The aim of this study was to measure the influence of the amount of two SPF 30 sunscreens on pre-vitamin D formation in a cuvette with 7-dehydrocholesterol. Sunscreen with physical (reflecting) or chemical (absorbing) UV filters exhibits different levels of protection in vitro even if the SPF is the same. The level of photoprotection is differentially reduced when less sunscreen than the recommended application thickness is applied. The usual application of 0.8-1 mg/cm(2) is below the recommended value of 2 mg/cm(2), and pre-vitamin D may be formed when lower amounts of SPF ≤30 sunscreen are applied, showing that a significant amount of UV radiation may enter the skin.

A total of 51 participants were randomly assigned to a control (n = 11), 2 treatment, or 2 sham groups (n = 10 per group). Participants underwent an 8-minute acclimatizing period. The HRV tachygram (RR interval) data were recorded directly into a Suunto watch (model T6; FitzWright Company Ltd, Langley, British Columbia, Canada). We analyzed the 5-minute pretreatment and posttreatment intervals. The spectral analysis of the tachygram was performed with Kubios software. All groups decreased in value except the control group that reacted in the opposite direction, when comparing the pretests and posttests for the high-frequency component. The very low frequency increased in all groups except the control group. The low frequency decreased in all groups except the sham pain-free group. The low frequency-high frequency ratio decreased in the treatment pain group by 0.46 and in the sham pain-free group by 0.26. The low frequency-high frequency ratio increase was 0.13 for the sham pain group, 0.04 for the control group, and 0.34 for the treatment pain-free group. The mean RR increased by 11.89 milliseconds in the sham pain-free group, 18.65 milliseconds in the treatment pain group, and 13.14 milliseconds in the control group. The mean RR decreased in the treatment pain-free group by 1.75 milliseconds and by 0.01 milliseconds in the sham pain group. Adjusting the lumbar vertebrae affected the lumbar parasympathetic nervous system output for this group of participants. Adaptation in the parasympathetic output, reflected by changes in high frequency, low frequency, and very low frequency, may be independent of type of adjustment. Therefore, the group differences found in the

    To compare standing head posture measurements between patients with nontraumatic neck pain (NP) and pain-free individuals. Single-blind (assessor) cross-sectional study. Hospital and general community. Consecutive patients (n=40) with chronic nontraumatic NP and age- and sex-matched pain-free participants (n=40). Not applicable. Three angular measurements: the angle between C7, the tragus of the ear, and the horizontal; the angle between the tragus of the ear, the eye, and the horizontal; and the angle between the inferior margins of the right and the left ear and the horizontal were calculated through the digitization of video images. NP patients were found to have a significantly smaller angle between C7, the tragus, and the horizontal, resulting in a more forward head posture than pain-free participants (NP, mean +/- SD, 45.4 degrees +/-6.8 degrees ; pain-free, mean +/- SD, 48.6 degrees +/-7.1 degrees ; P50y) revealed an interaction, with a statistically significant difference in head posture for younger participants with NP compared with younger pain-free participants (NP, mean +/- SD, 46.1 degrees +/-6.7 degrees ; pain-free, mean +/- SD, 51.8 degrees +/-5.9 degrees ; Ppain-free, mean +/- SD, 45.1 degrees +/-6.7 degrees ; P>.05; CI for the difference between groups, -4.9 degrees -4.2 degrees ). No other differences were found between patients and pain-free participants. Younger patients with chronic nontraumatic NP were shown to have a more forward head posture in standing than matched pain-free participants. However, the difference, although statistically significant, was perhaps too small to be clinically meaningful.

Foram mensurados e comparados, para tanto, a idade aos 100 quilos (IA, o ganho de peso diário (GPD, a conversão alimentar (CA e a espessura de toucinho (ET de um grupo com 42 machos, provenientes de granjas convencionais (grupo SC e outro com 113 machos, oriundos de granja SPF (grupo SPF. A média de peso corporal dos animais de ambos os grupos era de aproximadamente 30 quilos, ao início do experimento. A comparação entre as médias obtidas, para cada um dos parâmetros estudados, revelou produtividade estatisticamente significativa e superior em favor do grupo SPF. Assim, as IAs, os G PDs, as CAs e as ETs, obtidas para os grupos SPF e SC foram de, respectivamente, 150,49 e 156,4 dias, 897,78 e 955,19 gramas, 2,17:1 e 2,39:1 e 16,13 e 13,95mm. No grupo SPF, conforme evidenciado, observou-se um maior acúmulo de tecido adiposo, fato que sugere um menor dispêndio de energia para o combate a enfermidades crônicas, neste grupo de animais. Com base em projeção econômica dos resultados obtidos, os autores sugerem que a criação de animais SPF, embora possa exigir algum trabalho para sua implantação, é extremamente vantajosa, representando alternativa viável para a suinocultura brasileira.

  7. Using SpF to Achieve Petascale for Legacy Pseudospectral Applications

    Pseudospectral (PS) methods possess a number of characteristics (e.g., efficiency, accuracy, natural boundary conditions) that are extremely desirable for dynamo models. Unfortunately, dynamo models based upon PS methods face a number of daunting challenges, which include exposing additional parallelism, leveraging hardware accelerators, exploiting hybrid parallelism, and improving the scalability of global memory transposes. Although these issues are a concern for most models, solutions for PS methods tend to require far more pervasive changes to underlying data and control structures. Further, improvements in performance in one model are difficult to transfer to other models, resulting in significant duplication of effort across the research community. We have developed an extensible software framework for pseudospectral methods called SpF that is intended to enable extreme scalability and optimal performance. Highlevel abstractions provided by SpF unburden applications of the responsibility of managing domain decomposition and load balance while reducing the changes in code required to adapt to new computing architectures. The key design concept in SpF is that each phase of the numerical calculation is partitioned into disjoint numerical kernels that can be performed entirely inprocessor. The granularity of domain decomposition provided by SpF is only constrained by the datalocality requirements of these kernels. SpF builds on top of optimized vendor libraries for common numerical operations such as transforms, matrix solvers, etc., but can also be configured to use open source alternatives for portability. SpF includes several alternative schemes for global data redistribution and is expected to serve as an ideal testbed for further research into optimal approaches for different network architectures. In this presentation, we will describe our experience in porting legacy pseudospectral models, MoSST and DYNAMO, to use SpF as well as present preliminary

    The aim of this study was to determine whether clinical indicators of cutaneous allodynia predict the success of migraine therapy with sumatriptan using a brief questionnaire. Using quantitative sensory testing (QST) recent studies demonstrate that the presence of cutaneous allodynia, a clinical manifestation of central sensitization, can be detrimental to the success of migraine therapy with sumatriptan. QST is costly and requires much time, therefore it is not feasible to use in clinical practice. In this prospective study, migraineurs completed a questionnaire about their skin sensitivity during migraine. Each migraineur treated 2 migraine headaches with sumatriptan (100 mg): 1 headache at the earliest sign of migraine pain (mild, within 1 hour of onset) and 1 headache at least 4 hours after the onset of pain while moderate or severe. Thirty-six migraine headaches were evaluated in 18 migraineurs. A total of 44% of the headaches were not associated with allodynia at any time. Irrespective of allodynic status, headaches were more likely to become pain-free with early versus late treatment (2 hours; 78% vs. 33%, respectively). Headaches were equally likely to become pain-free when allodynia was reported before treatment but not 2 and 4 hours after treatment (2 hours; 67 vs. 63%, respectively, 4 hours 80 vs. 81%, respectively). However, no headaches were pain-free when allodynia was reported at 2 and 4 hours after treatment. Headaches without allodynia were aborted when treated early or late, and headaches with allodynia were aborted only when allodynia was not present after treatment. These findings suggest that different mechanisms account for allodynia before and after treatment; a developing phase in which central sensitization depends on incoming pain signals from the peripheral nociceptors and an established phase in which the sensitization becomes independent of the pain signals that come from the dura.

    MicroRNAs have emerged as important biomarkers and modulators of pathophysiological processes including oncogenesis and neurodegeneration. MicroRNAs are found to be involved in the generation and maintenance of pain in animal models of inflammation and neuropathic pain. Recently, microRNA dysregulation has been reported in patients with painful conditions such as complex regional pain syndrome and fibromyalgia. The aim of this study was to assess whether serum microRNA alterations occur during migraine attacks and whether migraine manifests in chronic serum microRNA aberrations. Two cohorts of 24 migraineurs, and age- and sex-matched healthy controls were included. High-content serum microRNA (miRNA) arrays were used to assess the serum microRNA profiles of migraineurs during attacks and pain-free periods in comparison with healthy controls. Of the 372 assessed microRNAs, 32 or ≈ 8% were found to be differentially expressed and 4 of these--miR-34a-5p, 29c-5p, -382-5p, and -26b-3p--were selected for further investigation. Migraine attacks were associated with an acute upregulation in miR-34a-5p and miR-382-5p expression. Interestingly, miR-382-5p not only exhibited an upregulation during attack but also proved to be a biomarker for migraine when comparing migraineurs in pain-free periods to the healthy control group (p = pain-free periods. This finding sheds light on the potential role of microRNAs in the pathophysiology of migraine and adds a new approach towards potential identification of much sought-after serum biomarkers of migraine.

    Repeated measures. To investigate motor control (MC) patterns of normal subjects during the low level physical load of the active straight leg raise (ASLR). Aberrant MC patterns, as observed with the ASLR test, are considered to be a mechanism for ongoing pain and disability in subjects with chronic musculoskeletal pelvic girdle pain. These patterns may not only affect the provision of lumbopelvic stability, but also respiration and the control of continence. Greater understanding of MC patterns in pain-free subjects may improve the management of pelvic girdle pain. METHODS.: Fourteen pain-free nulliparous women were examined during the ASLR. Electromyography of the anterior abdominal wall, right chest wall and the anterior scaleni, intraabdominal pressure (IAP), intrathoracic pressure (ITP), respiratory rate, pelvic floor kinematics, and downward leg pressure of the nonlifted leg were compared between a left and right ASLR. There was greater activation of obliquus internus abdominis and obliquus externus abdominis on the side of the ASLR. The predominant pattern of activation for the chest wall was tonic activation during an ipsilateral ASLR, and phasic respiratory activation lifting the contralateral leg. Respiratory fluctuation of both IAP and ITP did not differ lifting either leg. The baseline shifts of these pressure variables in response to the physical demand of lifting the leg was also the same either side. There was no difference in respiratory rate, pelvic floor kinematics, or downward leg pressure. Pain-free subjects demonstrate a predominant pattern of greater ipsilateral tonic activation of the abdominal wall and chest wall on the side of the ASLR. This was achieved with minimal apparent disruption to IAP and ITP. The findings of this study demonstrate the plastic nature of the abdominal cylinder and the flexibility of the neuromuscular system in controlling load transference during an ASLR.

    The aim of this study was to compare panoramic radiographic findings between subjects with reported facial pain and pain-free controls in a population-based sample of 34-year olds. The study was a part of a comprehensive medical survey including subjects born in the year 1966 in Northern Finland. A sub-sample of the cohort was formed based on the question concerning facial pain. A panoramic radiograph was taken of 48 subjects with facial pain and 47 pain-free controls. Pathological findings in the dentition, jaws, maxillary sinuses and temporomandibular joints (TMJs) were compared between the groups. The majority of the subjects in both groups did not have pathological findings. Compared with controls, the subjects with facial pain did not show significantly more pathological findings in the teeth, periodontium, maxillary sinuses, TMJs or in the other areas. Radiographic panoramic findings had no association with reported facial pain in the population-based sample of young adults, and have little impact on the diagnosis of facial pain.

    This study evaluated whether electrodermal resistance at acupuncture points (AP) systematically varies as a function of pain. The study was conceived as a proof-of-principle study in support of research on acupuncture and other complementary medicine approaches. Specifically, this study investigates whether or not electrodermal activity systematically differentiates arthritis patients with current pain from pain-free controls. Participants with rheumatoid arthritis (n = 32) and a typical pain level of at least 3 (on a 0-10 scale) were compared with case controls (n = 28) who had no medical diagnosis and were pain free. Electrodermal resistance at AP was measured with a commercial ohmmeter and compared to heart rate, blood pressure, and ratings on the Pain Catastrophization Scale and the McGill Melzack Pain Questionnaire. There were consistent differences between the experimental group and the control group on all markers of pain. Similarly, there were significant group differences and some trends for electrodermal activity at the AP labeled 'bladder,' 'gall bladder,' and 'small intestine.' It is concluded that the concept of electrodermal resistance at AP possesses criterion validity for distinguishing pain from a no pain state. This research provides support for the usefulness of measuring electrodermal activity when testing energy-based models of disease, and can be seen as a bridge between Western and Chinese medicine.

    To assess the effect of pain-free treadmill training on red blood cell deformability and walking distance in patients with claudication. Randomized-controlled trial of exercise training. Patients were recruited from the primary care, vascular outpatient clinic. A total of 60 patients with peripheral arterial occlusive disease (stage II according to Leriche-Fontaine) were randomized into the treadmill program or a control group. Fifty-five patients completed the study (27 in the exercising group and 28 in the control group). Patients in the exercising group were walking on the treadmill 3 times a week for 3 months. Each session consisted of 1 hour repetitive walking [performed to 85% of the pain-free walking time (PFWT)] was supervised by a qualified physiotherapist. Changes in erythrocyte deformability and treadmill walking performance (PFWT, maximal walking time) were assessed in both groups before the study and after 3 months. After 3 months of treadmill training, red blood cell deformability in the exercising group significantly increased (Ppain-free treadmill training is associated with a significant increase in red cell deformability in patients with claudication.

    Scapular dyskinesis is a major etiological factor in overhead athletes' shoulder problems. Our hypotheses were to evaluate if (1) visual observation of scapular dyskinesis during scaption has substantial interobserver reliability, and (2) scapular dyskinesis may be induced by swim training in pain-free swimmers. A reliability and observational study. Bachelor project at a college institution and at a private sports orthopedic hospital. Seventy-eight competitive swimmers with no history of shoulder pain were included in the study. Fourteen swimmers were evaluated regarding reliability. Inclusion criteria were competitive swimmers with high training volume who previously had no shoulder pain. Observations of scapular dyskinesis (yes/no) during simple scaption. The interobserver reliability of scaption and wall push-up was evaluated in 14 swimmers using kappa analysis. Prevalence of scapular dyskinesis at 4 time intervals during a swim training session. The scaption test resulted in a weighted kappa value of 0.75. Scapular dyskinesis was seen in 29 shoulders (37%) after the first time interval, in another 24 (cumulated prevalence 68%) after one-half of the training session, and in an additional 4 swimmers (cumulated prevalence 73%) after three-quarters of the training session. During the last quarter of the training session, another 7 swimmers had dyskinesis, resulting in a cumulated prevalence of 82%. The prevalence of abnormal scapular kinesis during a normal training session is high in previously pain-free swimmers. The prevalence increases with more training and occurs early during the training session.

    The in vitro evaluation of SPF is still a problem due to the lack of repeatability and correlation between the in vitro and in vivo data, and many authors are currently working to develop an internationally harmonized method. Very recently, the use of several "adjuvant" ingredients such as boosters, antioxidants, immunomodulators, solvents and film-forming ingredients have further complicated the pattern for product developers that should frequently run in vivo test. The aim of this study was to understand whether a simple and cheap in vitro method could be optimized in order to provide both statistically repeatable and predictive SPF measurement. In vitro SPF assessments were carried out on 75 commercial products. The SPF was measured according to two laboratory methods (A and B), using different substrates (PMMA and surgical tape Transpore™), quantity of product and spectrophotometers. In order to evaluate whether a standard technique of spreading could lead to a statistically reliable result, we applied different spreading pressure (100 g and 200 g). Furthermore, we investigate whether other parameters characterizing the product (SPF category, filter and texture) might represent statically significant variables affecting the measures. We then compared the results obtained from in vitro SPF measure of 11 products to in vivo SPF, in order to assess the predictability of in vitro methods. Several problems were encountered in confirming the weakness of the in vitro procedures. Pressure, SPF category, filter and texture did not affect significantly the results. Overall best results were obtained with the B2 method that in terms of repeatability and predictivity provided statistically better results. Method A with Transpore™ tape showed better in vitro-in vivo correlation than Method B with PMMA plates. In our investigation, we demonstrated that it is possible for a single laboratory to optimize internal methods and protocols to achieve repeatable and predictive

    Currently there is a lack of large population studies that have investigated pain sensitivity distributions in healthy pain free people. The aims of this study were: (1) to provide sex-specific reference values of pressure and cold pain thresholds in young pain-free adults; (2) to examine the association of potential correlates of pain sensitivity with pain threshold values. This study investigated sex specific pressure and cold pain threshold estimates for young pain free adults aged 21-24 years. A cross-sectional design was utilised using participants (n=617) from the Western Australian Pregnancy Cohort (Raine) Study at the 22-year follow-up. The association of site, sex, height, weight, smoking, health related quality of life, psychological measures and activity with pain threshold values was examined. Pressure pain threshold (lumbar spine, tibialis anterior, neck and dorsal wrist) and cold pain threshold (dorsal wrist) were assessed using standardised quantitative sensory testing protocols. Reference values for pressure pain threshold (four body sites) stratified by sex and site, and cold pain threshold (dorsal wrist) stratified by sex are provided. Statistically significant, independent correlates of increased pressure pain sensitivity measures were site (neck, dorsal wrist), sex (female), higher waist-hip ratio and poorer mental health. Statistically significant, independent correlates of increased cold pain sensitivity measures were, sex (female), poorer mental health and smoking. These data provide the most comprehensive and robust sex specific reference values for pressure pain threshold specific to four body sites and cold pain threshold at the dorsal wrist for young adults aged 21-24 years. Establishing normative values in this young age group is important given that the transition from adolescence to adulthood is a critical temporal period during which trajectories for persistent pain can be established. These data will provide an important research

Sixty-eight patients with peripheral obstructive arterial disease and intermittent claudication (Fontaine stage II) were randomly assigned into the treadmill training (repetitive intervals to onset of claudication pain, three times a week) or a control group (no change in physical activity) over 3 months. Both groups performed treadmill test to assess pain-free walking time (PFWT) and maximal walking time (MWT) and had blood analyses [for haematocrit, fibrinogen, triglycerides, and cholesterol: total, high-density lipoprotein (HDL) and low-density lipoprotein (LDL)] done at baseline and after 6 and 12 weeks of the study.

    [Purpose] This study prescribed pain-free range exercises for a female amateur skier who complained of limitations in her shoulder range of motion, and pain caused by protective spasms; the tester evaluated the effects of such exercise on pain. [Subject and Methods] A 23-year-old female who complained of pain of 3 weeks in duration in the right glenohumoral and scapulothoracic joints was enrolled. [Results] After pain-free range exercises, the visual analog pain score was 2 and the shoulder flexion and abduction angles improved compared to the initial values. [Conclusion] Thus, this study suggests muscle-strengthening exercises within the pain-free range, rather than simple pain treatments, as therapy for acute muscle injuries in skiers.

    . The objective of this study was to determine the risk for five forms of suicidality in rehabilitation acute pain patients (APPs) and rehabilitation chronic pain patients (CPPs) vs pain-free community controls. The Battery for Health Improvement 2 was developed utilizing a healthy (pain-free) community sample (N = 1,478), a community patient sample (N = 158), and a rehabilitation patient sample (N = 777). These groups were asked five suicidality questions relating to history of wanting to die, wanting to die because of pain, recent frequent suicide ideation, having a suicide plan, and history of suicide attempt. Of the rehabilitation patients, 326 were identified as being APPs, 341 as being CPPs, and 110 as having no pain. The risk for affirming each of the five suicidality questions was calculated for rehabilitation APPs, rehabilitation CPPs, and rehabilitation patients without pain utilizing the healthy pain-free community sample as the reference group. In addition, risk was calculated for various subgroups of rehabilitation patients: those with worker's compensation status, with litigation status, and with personal injury status. There are a variety of settings. In rehabilitation CPPs the risk for suicidality was greater than community pain-free controls for three suicidality questions: history of wanting to die, recent frequent suicide ideation, and having a suicide plan. Worker's compensation status, litigation status, and personal injury status appeared to increase risk for affirmation of some types of suicidality in CPPs. Rehabilitation APPs were at greater risk for all five suicidality items than the community pain-free controls. Rehabilitation CPPs are at greater risk for some forms of suicidality than community pain-free controls. This risk is increased by variables such as worker's compensation status, litigation status, and personal injury status. However, it is yet unclear if these variables actually predict suicidality as this requires further

    Despite its clinical relevance, the pathophysiology of pain in Parkinson's disease (PD) is still largely unknown, and both central and peripheral mechanisms have been invoked. To investigate whether central pain processing is altered in "drug-naive" pain-free PD (dnPD) patients. Using event-related functional MRI (fMRI), functional response to forearm heat stimulation (FHS) at two different intensities (41°C and 53°C) was investigated in 20 pain-free dnPD patients, compared with 18 healthy controls (HCs). Secondary analyses were performed to evaluate associations between BOLD signal changes and PD clinical features and behavioral responses. During low-innocuous FHS (41°C), no activation differences were found between dnPD patients and HCs. During high-noxious FHS (53°C) a significantly increased activation in the left somatosensory cortex, left cerebellum, and right low pons was observed in dnPD patients compared to HCs. In the latter experimental condition, fMRI BOLD signal changes in the right low pons (p < .0001; R = -0.8) and in the cerebellum (p = .004; R = -0.7) were negatively correlated with pain intensity ratings only in dnPD patients. No statistically significant difference in experimental pain perception was detected between dnPD patients and HCs. Our findings suggest that a functional remodulation of pain processing pathways occurs even in the absence of clinically overt pain symptoms in dnPD patients. These mechanisms may eventually become dysfunctional over time, contributing to the emergence of pain symptoms in more advanced PD stages. The comprehension of pain-related mechanisms may improve the clinical approach and therapeutic management of this disabling nonmotor symptom. © 2017 Wiley Periodicals, Inc.

    To compare the functional stability of Cetaphil UVA/UVB Defense SPF 50 as measured by its ultraviolet B sun protection factor (UVB-SPF) and ultraviolet A protection factor (UVA-PF) values following exposure to natural sunlight versus the UVB-SPF and UVA-PF values of unexposed product. These two randomized, controlled, evaluator-blinded, single-center trials were conducted according to the methods outlined in the 2007 Proposed Amendment to the Final Monograph, “Sunscreen Drug Products for Over-the-Counter Human Use.” Sunscreen samples were applied to glass plates and exposed to ultraviolet radiation in the form of natural sunlight in four minimal erythemal doses (MED) ranging from 2–6 MED (42–36 mJ/cm2). Three test sites were identified on the back of each study subject. Exposed sunscreen (one of four doses), unexposed sunscreen, and a UVB-SPF 15 control sunscreen were applied to the three test sites in a randomized fashion, followed by UV irradiation of incremental doses. Erythema and pigment darkening responses were assessed immediately following UV exposure and again 16–24 hours (erythema) or three to 24 hours (pigment darkening) after exposure. UVB-SPF and UVA-PF values were calculated for the exposed and unexposed samples. The calculated UVB-SPF and UVA-PF values for all test samples (exposed and unexposed) were >50 and >9, respectively, which were greater than the stated UVB-SPF and UVA-PF values on the product label. No differences were observed between the exposed and unexposed samples in UVB-SPF or UVA-PF. The UVA and UVB protection using standard evaluation techniques of Cetaphil UVA/UVB Defense SPF 50 remains stable despite exposure of the sunscreen to natural sunlight containing UVB ranging from 2–16 MED (41–336 mJ/cm2) and coexistent UVA.

Few studies have examined associations between experimentally induced pain sensitivity and physical activity in adults with chronic low back pain and pain-free controls. The objective of this study was to examine associations between physical activity levels and how an individual processes pain using experimentally induced pain stimuli. Seventy subjects (CLBP = 49; mean age = 46.8 ± 14.9; Pain-free = 21; mean age = 45.3 ± 18.2, n of females = 46) participated. A self-report questionnaire derived from the International Physical Activity Questionnaire (IPAQ) was used to calculate an activity level index. Pain sensitivity was assessed via quantitative sensory testing (QST) at the right lower extremity. Moderate (U = 688, ppain-free vs. individuals with CLBP. Activity level was not associated with pain sensitivity (Pain-free: R2 = 0.02, p> 0.05; CLBP: R2 = 0.01, p> 0.05). Both moderate (R2 = 0.49, ppain-free individuals. Findings suggest that physical activity influences pain modulation amongst pain-free individuals, however no relationship exists once CLBP is present. However, future investigation will elucidate the extent to which physical activity level either prevents CLBP or is effective in alleviating CLBP.

    Measurement Reliability. The purpose of the study was to evaluate the test-retest reliability of one vs. the mean of three trials of pain-free grip strength in participants with rheumatoid arthritis (RA). The study used was a repeated-measures, crossover design. Pain-free grip strength was measured with the Biometric E-Link Evaluation System V900S (Unit 25, Nine Mile Point Ind. Est., Gwent UK NP11 7HZ), pain levels recorded before and after grip tests with visual analog scale. High levels of test-retest reliability (intraclass correlation coefficient≥0.91) were found for both one trial and the mean of three trials of pain-free grip strength testing. Median values of grip strength for both methods produced comparable results. Clinically small but statistically significant increases in pain (p≤0.01) were found. One trial of pain-free grip strength is reliable and may save valuable clinical time while reducing the assessment burden placed on patients with RA. N/A. Copyright © 2010 Hanley & Belfus.

    A new lancet with an extremely small needle (0.15 mm diameter and 0.75 mm length) mounted on a small pedestal was tested in diabetic patients for blood glucose measurement in a randomized clinical study. A total of 37 diabetic patients were enrolled for the study. A pain scale categorized from 0 to 3 was created to measure the intensity of puncture pain which was explained to patients before testing. The patients' fingers were punctured with their own old style lancets at least 1 hour before the punctures by the new lancets, and puncture pains recorded according to the pain scale. All patients tested with the new lancet reported no pain and recorded the puncture pain as scale 0. Among the total 37 patients tested with their old style lancets, 2 patients (5.40%) reported no pain and recorded the pain as scale 0, thirteen patients (35.14%) recorded as scale 1, 16 patients (43.24%) as scale 2, and 6 patients (16.22%) as scale 3. The average pain scale of the patients who used old style lancets was 1.702 with the standard error 0.133. The chi-square goodness-of-fit test shows that the proportion of the pain scales comes from the claimed distribution with unequal frequencies, and chi-square tests for independence indicate that neither sex nor age of the sample patients is related to the pain scales.The paired t-test to test the existence of any difference in pain levels between the new lancet and the old style lancet showed; t = 1.702/0.133 = 12.796 with p-value Pain-free needle puncture was achieved by limiting the puncture depth to less than 0.75 mm with a thin needle with a 0.15 mm diameter. By allowing patients to see the new lancets before testing, psychological pain anticipation was minimized as the very thin and short needle is visually less intimidating. With a pain free puncture, better compliance and improved subsequent glucose levels may be achieved.

    This study was carried out to evaluate the effect of gamma irradiation on nutrient digestibility of either soy-based or milk-based diet for specific pathogen-free (SPF) mini-pigs. Gamma irradiation of the diets was done at dosage of 10 kGy with {sup 60}Co whereas autoclaving was executed at 121 {sup o}C for 20 min. Apparent crude protein digestibilities of gamma irradiated diets were higher (p<0.05) than those of autoclaved diets regardless of diet type. Digestibilities of dry matter, gross energy and total carbohydrate in the irradiated diet were higher than those of the autoclaved diet. From the results of nutrient digestibility of mini-pig diets in this study, 10 kGy gamma radiation was suggested as a convenient diet radicidation method that can minimize the decrease in nutrient digestibility on feeding to SPF mini-pigs.

    Studies have shown that swine HEV (sHEV) and rabbit HEV (rHEV) can experimentally infect rabbits and swine, respectively. However, no published data have documented isolating sHEV strains from rabbits in natural environment so far. To clarify the possibility of natural cross-species transmission of sHEV to rabbits, the pigs with HEV infection were farmed along with SPF rabbits in the same enclosed space. Five of 10 rabbits had seroconversion for anti-HEV antibody from the third week after mix-breeding. However, HEV RNA remained undetectable in feces, serum, liver and bile of the ten rabbits; and no obvious elevation of ALT was observed. The results possibly suggested that sHEV might lead to an inapparent infection of SPF rabbits by fecal-oral route. © 2015 Wiley Periodicals, Inc.

    One proposed mechanism of patellofemoral pain, increased stress in the joint, is dependent on forces generated by the quadriceps muscles. Describing causal relationships between muscle forces, tissue stresses, and pain is difficult due to the inability to directly measure these variables in vivo. The purpose of this study was to estimate quadriceps forces during walking and running in a group of male and female patients with patellofemoral pain (n = 27, 16 female; 11 male) and compare these to pain-free controls (n = 16, 8 female; 8 male). Subjects walked and ran at self-selected speeds in a gait laboratory. Lower limb kinematics and electromyography (EMG) data were input to an EMG-driven musculoskeletal model of the knee, which was scaled and calibrated to each individual to estimate forces in 10 muscles surrounding the joint. Compared to controls, the patellofemoral pain group had greater co-contraction of quadriceps and hamstrings (p = 0.025) and greater normalized muscle forces during walking, even though the net knee moment was similar between groups. Muscle forces during running were similar between groups, but the net knee extension moment was less in the patellofemoral pain group compared to controls. Females displayed 30-50% greater normalized hamstring and gastrocnemius muscle forces during both walking and running compared to males (ppain-free subjects. The muscle force data are available as supplementary material.

    Regulator of G-protein signaling 9-2 (RGS9-2) is a striatal-enriched signal-transduction modulator known to have a critical role in the development of addiction-related behaviors following exposure to psychostimulants or opioids. RGS9-2 controls the function of several G-protein-coupled receptors, including dopamine receptor and mu opioid receptor (MOR). We previously showed that RGS9-2 complexes negatively control morphine analgesia, and promote the development of morphine tolerance. In contrast, RGS9-2 positively modulates the actions of other opioid analgesics, such as fentanyl and methadone. Here we investigate the role of RGS9-2 in regulating responses to oxycodone, an MOR agonist prescribed for the treatment of severe pain conditions that has addictive properties. Using mice lacking the Rgs9 gene (RGS9KO), we demonstrate that RGS9-2 positively regulates the rewarding effects of oxycodone in pain-free states, and in a model of neuropathic pain. Furthermore, although RGS9-2 does not affect the analgesic efficacy of oxycodone or the expression of physical withdrawal, it opposes the development of oxycodone tolerance, in both acute pain and chronic neuropathic pain models. Taken together, these data provide new information on the signal-transduction mechanisms that modulate the rewarding and analgesic actions of oxycodone.

    Postoperative pain still poses a serious problem for 80% of patients undergoing surgery. We assessed the effects of the implementation of standards of postoperative analgesia, according to the guidelines of the "Pain-free hospital" project, and PROSPECT group recommendations, in the daily practice of a general surgical hospital ward. One hundred adult patients, scheduled for elective inguinal or umbilical hernia surgery, were included in the study and allocated to two groups, to receive analgesics on demand (control), or postoperative analgesia according to the introduced programs. The number of additional interventions and patients' satisfaction were chosen as primary end points to assess the clinical value of the introduced standards. Additionally, the type and dose of analgesics, and duration of hospital stay were noted. One additional intervention (2%) was required in the treated group, and 9 (18%) - in the control group (p=0.023). In the treated group, the patient satisfaction (0 to 10) score was rated 9 by 39 patients (78%) and 10 by 11 patients (22%). The duration of hospitalisation was similar in both groups. We confirmed the success of introducing the standards of pain treatment into the daily practice of a surgical ward.

    Alterations of respiratory patterns have been observed in pelvic girdle pain subjects during the active straight leg raise (ASLR). This study investigated how pain-free subjects coordinate motor control during an ASLR when this task is complicated by the addition of a respiratory challenge. Trunk muscle activation, intra-abdominal pressure, intra-thoracic pressure, pelvic floor motion, downward pressure of the non-lifted leg and respiratory rate were compared between resting supine, ASLR, breathing with inspiratory resistance (IR) and ASLR+IR. Subjects responded to ASLR+IR with an increase in the motor activation in the abdominal wall and chest wall compared to when ASLR and IR were performed in isolation. Activation of obliquus internus abdominis was greater on the side of the leg lift during the ASLR+IR, in comparison to symmetrical activation observed in the other abdominal wall muscles. The incremental increase of motor activity was associated with greater intra-abdominal pressure baseline shift when lifting the leg during ASLR+IR compared to ASLR. Individual variation was apparent in the form of the motor control patterns, mostly reflected in variable respiratory activation of the abdominal wall. The findings highlight the flexibility of the neuromuscular system in adapting to simultaneous respiratory and stability demands. 2009 Elsevier Ltd. All rights reserved.

    Inadequate pain care in health care facilities is still a major concern. Due to structural and organizational shortcomings the potential of modern analgesia is far from being exhausted. The project "Action Alliance Pain-free City Münster" is designed to analyze the multiprofessional pain management in health care facilities in the model City of Münster in an epidemiologic study and aims to optimize pain management in accordance with nursing standards and medical guidelines. Hospitals, nursing homes, outpatient nursing services, hospices and pain care centers will be examined. After an analysis of the current state on the basis of a pre-test, the necessary optimization measures will be developed and implemented. Subsequently, the pain management will be reevaluated in a post-test. In partly still unexplored health care areas of Germany, epidemiologic data will be generated, barriers to the implementation of standards and guidelines revealed and measures of improvements developed and tested. In addition, interface problems between the evaluated sectors will be identified. In this article the objective and the methods of the project are described.

    Intermittent claudication, a common symptom of peripheral arterial disease, results in insufficient blood flow and oxygen supply to lower extremity muscles. Compared to men, women with peripheral arterial disease have a higher rate of mobility loss with peripheral arterial disease due to poorer lower extremity functioning. This study evaluates the effect of supervised pain-free treadmill exercise on improving performance in women with intermittent claudication due to peripheral arterial disease in comparison to men. A total of 26 participants (women, n = 9, 34.62%; mean age = 67.58 ± 5.59 years; averaging 23.46 ± 3.91 visits and 10.46 ± 0.99 weeks in the program) diagnosed with peripheral arterial disease, with symptoms of intermittent claudication, partook in a 45 min treadmill walk, twice per week, below the participant's minimal pain threshold. Female participants' change scores showed 752%, 278% and 115% improvement in mean walking distance, duration and rate, respectively. Men improved 334%, 149% and 80%, respectively. Significant differences (p  0.80). Our results suggest that women reap similar benefits from this low-intensity treadmill program in comparison to men. © The Author(s) 2015.

    In a previous study, we demonstrated that control of the roughness of molded PMMA plates improves in vitro SPF reproducibility. However, in vitro/vivo deviations are still observed. Sunscreens show different behavior during spreading on the HD6 surface according to the formulation, resulting in a more or less homogenous distribution. The hydrophilic nature of HD6 appears to contribute significantly during spreading. Two different sunscreens offering a homogenous and non-homogenous distribution were investigated to check if the interfacial tension between product and substrate has a real influence on the spreading quality. Using microscopic observations, we attempted to correlate the in vitro SPF results with the product's spreading property. In order to reduce this interfacial tension, an HD6 pretreatment with an amphoteric surfactant, cocamidopropyl betain, was performed. In vitro SPF on "pretreated HD6" was examined using a cohort of 30 products. This pretreatment led to reliable results, demonstrating good association with the in vivo SPF.

    Quantitative sensory tests are widely used in human research to evaluate the effect of analgesics and explore altered pain mechanisms, such as central sensitization. In order to apply these tests in clinical practice, knowledge of reference values is essential. The aim of this study was to determine the reference values of pain thresholds for mechanical and thermal stimuli, as well as withdrawal time for the cold pressor test in 300 pain-free subjects. Pain detection and pain tolerance thresholds to pressure, heat and cold were determined at three body sites: (1) lower back, (2) suprascapular region and (3) second toe (for pressure) or the lateral aspect of the leg (for heat and cold). The influences of gender, age, height, weight, body-mass index (BMI), body side of testing, depression, anxiety, catastrophizing and parameters of Short-Form 36 (SF-36) were analyzed by multiple regressions. Quantile regressions were performed to define the 5th, 10th and 25th percentiles as reference values for pain hypersensitivity and the 75th, 90th and 95th percentiles as reference values for pain hyposensitivity. Gender, age and/or the interaction of age with gender were the only variables that consistently affected the pain measures. Women were more pain sensitive than men. However, the influence of gender decreased with increasing age. In conclusion, normative values of parameters related to pressure, heat and cold pain stimuli were determined. Reference values have to be stratified by body region, gender and age. The determination of these reference values will now allow the clinical application of the tests for detecting abnormal pain reactions in individual patients.

    Conditioned pain modulation (CPM) encompasses the effects of inhibitory and facilitatory pain modulatory systems and is inefficient in some chronic pain states. A proportion of healthy subjects also exhibit little or no CPM, perhaps suggesting that inherent factors such as gender or genetics may be influential. However, there is no consensus on how best to determine a meaningful CPM effect. This study aimed to determine the proportion of pain-free subjects exhibiting a meaningful CPM effect. Analyses of associations between 5HTTLPR (serotonin transporter-linked polymorphic region) polymorphisms on the serotonin transporter gene (SLC6A4), gender, and CPM effect were also carried out. A total of 125 healthy subjects (47 male; 78 female) underwent pressure pain threshold testing before, during, and after a cold pressor conditioning stimulus. A buccal cell sample was collected for analysis of 5HTTLPR genotype. Meaningful CPM effect was determined as an increase in pressure pain threshold values from baseline greater than the inherent error of measurement, calculated as 5.3%. During the conditioning stimulus, 116 subjects (92.8%) exhibited a CPM effect whereas 9 did not. CPM effect did not differ significantly between genders or between 5HTTLPR genotypes. This provides a clear basis on which to determine the proportion of patients with a chronic pain disorder that exhibit a meaningful CPM effect. This study proposes a method for calculating meaningful CPM effect and reports the proportion and magnitude of effect elicited in a large sample. Associations between CPM, gender, and genotype were also analyzed. Clarification of normal CPM response may help to elucidate the mechanisms driving CPM inefficiency in chronic pain.

    To determine whether patients with a painful myofascial temporomandibular disorder (TMD) have diminished nocturnal heart rate variability (HRV), a marker of autonomic nervous system (ANS) dysfunction, relative to healthy, pain-free controls. Participants with myofascial TMD and healthy, pain-free volunteers underwent nocturnal polysomnography studies during which HRV indices were measured. Multiple linear regression analyses were used to determine whether TMD status exerted unique effects on HRV. Ninety-five participants (n = 37 TMD; n = 58 controls) were included in the analyses. The TMD group had a lower standard deviation of R-R intervals (89.81 ± 23.54 ms versus 107.93 ± 34.42 ms, P ⋜ .01), a lower root mean squared successive difference (RMSSD) of R-R intervals (54.78 ± 27.37 ms versus 81.88 ± 46.43 ms, P pain-free controls. Further research should focus on processes that address this ANS imbalance, which may potentially lead to effective therapeutic interventions.

    Patients with pain are more reactive to various types of sensations, not limited to pain alone. A potential useful instrument to assess reactivity is the Kohn Reactivity Scale (KRS). This study examines the psychometric characteristics of the KRS-Dutch version and its ability to differentiate between subjects with and without pain. Internal consistency, convergent validity, and test-retest reliability of the Dutch translation of the KRS were assessed in 321 pain-free control subjects and different subgroups of this sample. Subsequently, reactivity scores were compared between the pain-free subjects and 291 pain patients who were referred to a pain clinic for treatment. Reliability analyses indicated good internal consistency (α ≥ 0.77) and high test-retest reliability (intraclass correlation = 0.95) of the KRS in the control subjects. Validity analyses yielded positive correlations of the KRS with related constructs like pain vigilance and awareness (r = 0.37), symptom severity (r = 0.29), and the personality characteristic neuroticism (r = 0.20). Pain patients had overall significantly higher KRS scores than the pain-free subjects indicating increased reactivity, particularly for the patients with medically unexplained pain. These findings indicate that the KRS is a useful instrument to screen for reactivity in pain patients, which may be of particular relevance for those suffering from medically unexplained pain. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

    Factor-analytic studies of the structure of posttraumatic stress disorder (PTSD) symptoms have yielded inconsistent results. One of the reasons for the inconsistency may be that PTSD is highly comorbid with other disorders; the observed factor structure might depend on the particular comorbid disorder. One such disorder is chronic pain. The goal of the present study was to investigate whether PTSD symptom structure differs between pain and pain-free patients scheduled to undergo major surgery. Four hundred and forty-seven patients who were approached 7 to 10 days prior to scheduled surgery completed the PTSD Checklist-Civilian (PCL-C) Version and the Current Pain and Pain History Questionnaire; the latter was used to divide patients into pain (N = 175) and pain-free (N = 272) groups. Results showed that in pain-free patients, PTSD symptoms were best expressed as 2 symptom clusters (re-experiencing/avoidance; emotional numbing/hyperarousal) accounting for 52.4% of the variance. In pain patients, PTSD symptoms were best expressed as a single symptom cluster accounting for 51.1% of the variance. These results suggest different interrelationships among PTSD symptoms in these 2 populations. Results reflect the need for (1) controlling for pain in studies looking at PTSD-symptom expression and (2) further research on PTSD-symptom expression in pain populations. These results may have important implications for research on the comorbidity between PTSD and chronic pain, as well as for treatment of PTSD symptoms in patients presenting with pain problems.

    For many diabetic patients, years of blood glucose self-monitoring (SM) with readings taken several times daily is an inevitable aspect of insulin therapy. We investigated whether SM from abdominal skin might be an alternative to the established fingertip method. A total of 63 diabetic patients and 16 nondiabetic volunteers determined their blood glucose in parallel in capillary blood from the tip of the finger and from abdominal skin 5 times daily on 5 successive days. The blood samples were collected from the two test regions using lancing devices, and the SM determinations were all done with a meter. Consecutive specific enzymatic glucose determinations in blood from the fingertip served as the reference method. The results of the SM from abdominal skin, a method perceived as virtually painless, were in close correlation with the control laboratory determinations and with SM from the finger (Pearson's r, 0.94 and 0.95). The comparison of SM method for abdomen vs. finger laboratory control gave a linear regression equation of y=8.35+0.94x (r=0.94). Error grid analysis revealed: range A, 93.6%; range B, 5.4%; range C, 0.05%; range D, 1.0%; and range E, 0%. Bland and Altman analysis yielded the mean of the differences, 0.2 mg/dl; 2 SD, 32 mg/dl; minimum, -162 mg/dl; maximum, 148 mg/dl. Laboratory glucose determinations in capillary blood from the fingertip and from abdominal skin led in 99.7% of the cases to concordant therapeutic decisions in the diabetics; the sample material was therefore equivalent. The practical aspects (afterbleeding, number of punctures, test strip consumption) of SM from the two regions showed no essential differences. However, only 22% of the diabetic patients investigated continued to perform SM from abdominal skin on a longer basis. In a further 5 adipose diabetic patients (BMI, 32 kg/M2), SM from abdominal skin was not practicable, as there was insufficient blood to collect. SM from abdomal skin is a simple, virtually pain-free and

    Formulation of sunscreen products to obtain high values of sun protection factor (SPF) and protection from ultraviolet A (PA) is challenging work for cosmetic chemists. This study aimed to study factors affecting SPF and PA values using ultraviolet transmission spectroscopy as well as texture profiles of sunscreen formulations using 23 factorial designs. Results demonstrate that the correlation coefficient between the labeled SPF values of counter-brand sunscreen products and the in vitro SPF values was 0.901. In vitro SPF determination showed that the combination effect of phase volume ratio (PVR) and xanthan gum caused a significant increase to the SPF values of the formulations, whereas the interaction effect between PVR and stearic acid significantly decreased the SPF value. In addition, there was the interaction effect between xanthan gum and stearic acid leading to significant reduction of hardness, compressibility, and pH, but significantly increasing the adhesiveness. All tested factors did not significantly affect the cohesiveness of tested formulations. In conclusion, apart from sunscreen agents, the other ingredients also affected the SPF and PA values. The calculated SPF values range from 21 to 60. However, a selected formulation needs to be confirmed by the standard method of testing. In addition, the physical, chemical, and biological stability; shelf life; and sensory evaluation of all formulations need to be evaluated.

    Full Text Available Segmentation of regions of interest is a well-known problem in image segmentation. This paper presents a region-based image segmentation technique using active contours with signed pressure force (SPF function. The proposed algorithm contemporaneously traces high intensity or dense regions in an image by evolving the contour inwards. In medical image modalities these high intensity or dense regions refer to tumor, masses, or dense tissues. The proposed method partitions an image into an arbitrary number of subregions and tracks down salient regions step by step. It is implemented by enforcing a new region-based SPF function in a traditional edge-based level set model. It partitions an image into subregions and then discards outer subregion and partitions inner region into two more subregions; this continues iteratively until a stopping condition is fulfilled. A Gaussian kernel is used to regularize the level set function, which not only regularizes it but also removes the need of computationally expensive reinitialization. The proposed segmentation algorithm has been applied to different images in order to demonstrate the accuracy, effectiveness, and robustness of the algorithm.

    Little evidence exists regarding parameter selection for hypoalgesia using interferential therapy (IFT). This study investigated segmental and extrasegmental hypoalgesic effects of different IFT parameter combinations upon experimentally induced pressure pain threshold (PPT) in pain-free volunteers. The participants were randomly assigned to 6 groups: control, placebo, bipolar constant amplitude modulation frequency (AMF), bipolar sweep AMF, quadripolar constant AMF, and quadripolar sweep AMF. The study was conducted in a university laboratory. One hundred eighty adults who were healthy and pain-free participated in the study. Interferential therapy was delivered to all groups at high, to-tolerance intensity and at high AMF. Stimulation to the dominant forearm was delivered for 30 minutes, with monitoring for a further 30 minutes. Pain pressure threshold was measured at the area of first dorsal interosseous muscle of the dominant and nondominant hands (segmental measurements) and over the tibialis anterior muscle (extrasegmental measurement) at baseline and at 10-minute intervals using a pressure algometer. Square root transformed PPT data were analyzed using repeated-measures analysis of variance. There was a significant change in PPT over time, but no significant between-subjects difference in segmental or extrasegmental PPT between any of the IFT groups and the placebo or control group. Thus, IFT delivered in any of these parameter combinations did not significantly affect the PPT of pain-free participants compared with the control or placebo group. Success of blinding was not evaluated. This study showed that IFT delivered at high, to-tolerance intensity and high AMF does not produce significant segmental and extrasegmental hypoalgesic effects on PPT in participants who were healthy compared with a control or placebo group. Further research is warranted to investigate the hypoalgesic effect of different IFT parameter combinations and to explain its possible

    Full Text Available IBDV Gm 11 (Simbios eleven-molecular group has been detected since 1997 in many farms of commercial broilers and layers causing high mortality (2 to 15% and severe macro and microscopic damage in cloacal bursae, spleen, thymus, kidney and liver. Five serial passages of 2050/97-Gm 11 IBDV sample by CAM route in SPF chicken's embryonated eggs did not elicit increased embryo mortality. High mortality (100% of 21 day-old SPF leghorn chickens and severe bursal and splenic lesions were seen from 24 up to 48 hours after eye-drop inoculation of 2050/97 strain (50 mL of 10-2 dilution of 10% bursae homogenate. Mortality was not detected when vaccinated SPF and broiler chickens were inoculated. One dead bird was found among ten challenged unvaccinated broilers. Variations in the intensity of cloacal bursae injury and spleen response were found between unvaccinated and vaccinated broiler chickens. IBDV antibodies were detected by ELISA test in almost all vaccinated SPF chickens before challenge while low number of commercial vaccinated and unvaccinated broilers were serologically positive (0 to 3 birds in 18. Increasing IBDV antibody titers were detected after challenge with 2050/97 strain and highest GMTs were found in broilers. It was concluded that 2050/97 strain is a highly virulent IBDV and SPF leghorn chickens immunized with BV8 intermediate vaccine strain were resistant to the challenge. Increasing susceptibility was found from experimental groups of unvaccinated broilers to vaccinated broilers and to unvaccinated SPF birds. It is discussed that passive immunity was involved in the rate of protection of challenged unvaccinated broiler and in the immune response impairment after vaccination of broilers chicks. The use of a constant virus suspension with known potency to challenge the experimental birds was suitable to evaluate vaccination efficacy. Evaluation of bursal and splenic responses at early and delayed time after challenge were useful to

    Understanding motion in the normal healthy foot is a prerequisite for understanding the effects of pathology and thereafter setting targets for interventions. Quality foot kinematic data from healthy feet will also assist the development of high quality and research based clinical models of foot biomechanics. To address gaps in the current literature we aimed to describe 3D foot kinematics using a 5 segment foot model in a population of 100 pain free individuals. Kinematics of the leg, calcaneus, midfoot, medial and lateral forefoot and hallux were measured in 100 self reported healthy and pain free individuals during walking. Descriptive statistics were used to characterise foot movements. Contributions from different foot segments to the total motion in each plane were also derived to explore functional roles of different parts of the foot. Foot segments demonstrated greatest motion in the sagittal plane, but large ranges of movement in all planes. All foot segments demonstrated movement throughout gait, though least motion was observed between the midfoot and calcaneus. There was inconsistent evidence of movement coupling between joints. There were clear differences in motion data compared to foot segment models reported in the literature. The data reveal the foot is a multiarticular structure, movements are complex, show incomplete evidence of coupling, and vary person to person. The data provide a useful reference data set against which future experimental data can be compared and may provide the basis for conceptual models of foot function based on data rather than anecdotal observations.

    Nonspecific arm pain (NSAP) is a common clinical entity, the pathophysiological mechanisms of which are poorly understood. The purpose of this study was to investigate sensory profiles in individuals with nonspecific arm pain compared with cervical radiculopathy and pain-free controls. Forty office workers with NSAP, 17 people with cervical radiculopathy, and 40 pain-free controls were assessed by means of quantitative sensory testing (thermal and vibration detection thresholds; thermal and pressure pain thresholds), tests for neural tissue sensitivity, and questionnaires. Between-group comparisons were conducted using Kruskal-Wallis tests. An exploratory factor analysis was used to determine characteristic features in NSAP. Both patient groups demonstrated cold and pressure pain sensitivity (P<0.003; P<0.05) and neural tissue sensitivity (P<0.001). The NSAP group also demonstrated heat pain sensitivity (P<0.001). Both patient groups demonstrated hypoaesthesia to vibration thresholds (P<0.05), whereas thermal hypoaesthesia was only evident in the cervical radiculopathy group (P<0.05). Exploratory factor analysis revealed pressure and thermal pain sensitivity as the key characteristics of this NSAP group. Sensory profiles in NSAP and cervical radiculopathy differ. NSAP is characterized by widespread sensitivity to thermal and pressure pain in the absence of thermal hypoaesthesia, whereas cervical radiculopathy is characterized by the presence of thermal and vibratory hypoaesthesia as well as more localized cold and pressure pain sensitivity. The identification of widespread sensory hypersensitivity in NSAP has important implications for clinical decision making.

    State-related brain structural alterations in patients with episodic tension-type headache (ETTH) are unclear. We aimed to conduct a longitudinal study to explore dynamic gray matter (GM) changes between the pain and pain-free phases in ETTH. We recruited 40 treatment-naïve ETTH patients and 40 healthy controls. All participants underwent brain structural scans on a 3.0-T MRI system. ETTH patients were scanned in and out of pain phases. Voxel-based morphometry analysis was used to determine the differences in regional gray matter density (GMD) between groups. Additional regression analysis was used to identify any associations between regional GMD and clinical symptoms. ETTH patients exhibited reduced GMD in the bilateral primary somatosensory cortex, and increased GMD in the bilateral anterior cingulate cortex (ACC) and anterior insula for the in pain phase compared with the out of pain phase. The out of pain phase of ETTH patients exhibited no regions with higher or lower GMD compared with healthy controls. GMD in the left ACC and left anterior insula was negatively correlated with headache days. GMD in the left ACC was negatively correlated with anxiety and depressive symptoms in ETTH patients. This is the first study to demonstrate dynamic and reversible GMD changes between the pain and pain-free phases in ETTH patients. However, this balance might be disrupted by increased headache days and progressive anxiety and depressive symptoms.

The strains were derived from Belgian and French commercially raised broilers with pneumonia. Both genotype B and D strains induced conjunctivitis, rhinitis, sinusitis, tracheitis, bronchitis, pneumonitis, airsacculitis, splenitis, hepatitis, nephritis, and enteritis in sequentially (days 2 to 34 post infection euthanized chickens. Inflammation of the ovaries was only observed in genotype D infected chickens. Overall, the genotype D strain caused more severe gross and histopathological lesions and mortality (54.5% early upon infection. The genotype D strain seemed to replicate faster as severity of the lesions increased more quickly. C. psittaci is a primary pathogen in chickens, and efficient monitoring and control of this emerging zoonotic pathogen is urgently needed.

    A significant fraction of airframe structure consists of stiffened panels that are costly and difficult to fabricate. This program explored a potentially lower-cost processing route for producing such panels. The alternative process sought to apply concurrent superplastic forming and adhesive bonding of aluminum alloy sheets. Processing conditions were chosen to balance adequate superplasticity of the alloy with thermal stability of the adhesive. As a first objective, an air-quenchable, superplastic aluminum-lithium alloy and a low-volatile content, low-viscosity adhesive with compatible forming/curing cycles were identified. A four-sheet forming pack was assembled which consisted of a welded two-sheet core separated from the face sheets by a layer of adhesive. Despite some preliminary success, of over 30 forming trials none was completely successful. The main problem was inadequate superplasticity in the heat-affected zones of the rib welds, which generally fractured prior to completion of the forming cycle. The welds are a necessary component in producing internal ribs by the 'four-sheet' process. Other challenges, such as surface preparation and adhesive bonding, were adequately solved. But without the larger issue of tearing at the weld locations, complex panel fabrication by SPF/AB does not appear viable.

    2014-06-01

    The Strategic Prevention Framework State Incentive Grant (SPF SIG) program is a national public health initiative sponsored by the U.S. Substance Abuse and Mental Health Services Administration's Center for Substance Abuse Prevention to prevent substance abuse and its consequences. State grantees used a data-driven planning model to allocate resources to 450 communities, which in turn launched over 2,200 intervention strategies to target prevention priorities in their respective populations. An additional goal was to build prevention capacity and infrastructure at the state and community levels. This paper addresses whether the state infrastructure goal was achieved, and what contextual and implementation factors were associated with success. The findings are consistent with claims that, overall, the SPF SIG program met its goal of increasing prevention capacity and infrastructure across multiple infrastructure domains, though the mediating effects of implementation were evident only in the evaluation/monitoring domain. The results also show that an initiative like the SPF SIG, which could easily have been compartmentalized within the states, has the potential to permeate more broadly throughout state prevention systems.

    This study examines (1) coalition survival, (2) prevalence of evidence-based prevention interventions (EBPIs) to reduce substance abuse implemented as part of the Tennessee Strategic Prevention Framework (SPF) State Incentive Grant (SIG), (3) EBPI sustainability, and (4) factors that predict EBPI sustainability. Secondary data were collected on 27 SPF SIG-funded coalitions and 88 EBPI and non-EBPI implementations. Primary data were collected by a telephone interview/web survey five and one-half years after the SPF SIG ended. Results from secondary data show that 25 of the 27 coalitions survived beyond the SPF SIG for one to five and one-half years; 19 coalitions (70%) were still active five and one-half years later. Further, 88 EBPIs and non-EBPIs were implemented by 27 county SPF SIG coalitions. Twenty-one (21) of 27 coalitions (78%) implemented one to three EBPIs, totaling 37 EBPI implementations. Based on primary survey data on 29 of the 37 EBPI implementations, 28 EBPIs (97%) were sustained between two and five and one-half years while 22 EBPI implementations (76%) were sustained for five and one-half years. When controlling for variability among coalitions (nesting of EBPIs in coalitions), increases in data resources (availability of five types of prevention data) was a strong predictor of length of EBPI sustainability. Positive change in extramural funding resources and level of expertise during SPF SIG implementation, as well as level of coalition formalization at the end of the SPF SIG predicted EBPI sustainability length. One intervention attribute (trialability) also predicted length of sustainability. Implications are discussed.

    Patients suffering from chronic pain may benefit from learning adaptive coping strategies. Consensus on efficient strategies for this group of patients is, however, lacking, and previous studies have shown inconsistent results. The present study has examined coping strategies in two distinctly different groups of chronic pain patients and a group of healthy controls. Thirty neuropathic pain (NP) patients, 28 fibromyalgia (FM) patients, and 26 pain-free healthy controls completed the Coping Strategy Questionnaire (CSQ-48/27) and rated their daily pain. The results showed that FM and NP patients did not cope differently with pain. The only difference between the groups was that FM patients felt more in control of their pain than NP patients. Both patient groups used more maladaptive/passive coping strategies, but surprisingly also more adaptive/active coping strategies than healthy controls. However, FM patients with high levels of passive strategies felt less in control than FM patients with low levels of passive strategies. This was not seen in NP patients. An important implication for clinical practice is therefore that passive coping strategies should be restructured into active ones, especially for FM patients. Otherwise, the same psychological treatment model can be applied to both groups since they use similar coping styles. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    In this work a novel self-powered microneedle-based transdermal biosensor for pain-free high-accuracy real-time measurement of glycaemia in interstitial fluid (ISF) is reported. The proposed transdermal biosensor makes use of an array of silicon-dioxide hollow microneedles that are about one order of magnitude both smaller (borehole down to 4µm) and more densely-packed (up to 1×10(6)needles/cm(2)) than state-of-the-art microneedles used for biosensing so far. This allows self-powered (i.e. pump-free) uptake of ISF to be carried out with high efficacy and reliability in a few seconds (uptake rate up to 1µl/s) by exploiting capillarity in the microneedles. By coupling the microneedles operating under capillary-action with an enzymatic glucose biosensor integrated on the back-side of the needle-chip, glucose measurements are performed with high accuracy (±20% of the actual glucose level for 96% of measures) and reproducibility (coefficient of variation 8.56%) in real-time (30s) over the range 0-630mg/dl, thus significantly improving microneedle-based biosensor performance with respect to the state-of-the-art.

    The purpose of the study was to compare hip agonist-antagonist isometric strength ratios between females with patellofemoral pain (PFP) syndrome and pain-free control group. One hundred and twenty females between 15 and 40 years of age (control group: n = 60; PFP group: n = 60) participated in the study. Hip adductor, abductor, medial rotator, lateral rotator, flexor, and extensor isometric strength were measured using a hand-held dynamometer. Comparisons in the hip adductor/abductor and medial/lateral rotator and flexor/extensor strength ratios were made between groups using independent t-tests. Group comparisons also were made between the anteromedial hip complex (adductor, medial rotator, and flexor musculature) and posterolateral hip complex (abductor, lateral rotator, and extensor musculature). On average, the hip adductor/abductor isometric strength ratio in the PFP group was 23% higher when compared with the control group (p = 0.01). The anteromedial/posterolateral complex ratio also was significantly higher in the PFP group (average 8%; p = 0.04). No significant group differences were found for the medial/lateral rotator ratio and flexor/extensor strength ratios. The results of this study demonstrate that females with PFP have altered hip strength ratios when compared with asymptomatic controls. These strength imbalances may explain the tendency of females with PFP to demonstrate kinematic tendencies that increase loading on the patellofemoral joint (i.e., dynamic knee valgus).

  7. New noninvasive approach assessing in vivo sun protection factor (SPF) using diffuse reflectance spectroscopy (DRS) and in vitro transmission.

    In the past 56 years, many different in vitro methodologies have been developed and published to assess the sun protection factor (SPF) of products, but there is no method that has 1:1 correlation with in vivo measurements. Spectroscopic techniques have been used to noninvasively assess the UVA protection factor with good correlation to in vivo UVA-PF methodologies. To assess the SPF of sunscreen product by diffuse reflectance spectroscopy (DRS) technique, it is necessary to also determine the absorbance spectrum of the test material in the UVB portion of the spectrum (290-320 nm). However, because of the high absorbance characteristics of the stratum corneum and epidermis, the human skin does not remit enough UVB radiation to be used to measure the absorption spectrum of the applied product on skin. In this work, we present a new method combining the evaluation of the absolute UVA absorption spectrum, as measured by DRS with the spectral absorbance 'shape' of the UVB absorbance of the test material as determined with current in vitro thin film spectroscopy. The measurement of the in vivo UVA absorption spectrum involves the assessment of the remitted intensity of monochromatic UVA radiation (320-400 nm) before and after a sunscreen product was applied on skin using a spectrofluorimeter Fluorolog 3, FL3-22 (Yvon Horiba, Edison, NJ, USA). The probe geometry assures that light scattering products as well as colored products may be correctly assessed. This methodology has been extensively tested, validated, and reported in the literature. The in vitro absorption spectrum of the sunscreen samples and polyvinyl chloride (PVC) films 'surrogate' sunscreen standards were measured using Labsphere® UV-2000S (Labsphere, North Sutton, NH, USA). Sunscreens samples were tested using PMMA Helioplates (Helioscience, Marseille, France) as substrates. The UVB absorbance spectrum (Labsphere) is 'attached' to the UVA absorbance spectrum (diffuse reflectance) with the UVB

    The goal of this study was to establish whether clear patterns of initial pain freedom could be identified when treating patients with classic trigeminal neuralgia (TN) by using Gamma Knife surgery (GKS). The authors compared hypesthesia and pain recurrence rates to see if statistically significant differences could be found. Between July 1992 and November 2010, 737 patients presenting with TN underwent GKS and prospective evaluation at Timone University Hospital in Marseille, France. In this study the authors analyzed the cases of 497 of these patients, who participated in follow-up longer than 1 year, did not have megadolichobasilar artery- or multiple sclerosis-related TN, and underwent GKS only once; in other words, the focus was on cases of classic TN with a single radiosurgical treatment. Radiosurgery was performed with a Leksell Gamma Knife (model B, C, or Perfexion) using both MR and CT imaging targeting. A single 4-mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.8 mm (range 4.5-14 mm) anterior to the emergence of the nerve. A median maximum dose of 85 Gy (range 70-90 Gy) was delivered. Using empirical methods and assisted by a chart with clear cut-off periods of pain free distribution, the authors were able to divide patients who experienced freedom from pain into 3 separate groups: patients who became pain free within the first 48 hours post-GKS; those who became pain free between 48 hours and 30 days post-GKS; and those who became pain free more than 30 days after GKS. The median age in the 497 patients was 68.3 years (range 28.1-93.2 years). The median follow-up period was 43.75 months (range 12-174.41 months). Four hundred fifty-four patients (91.34%) were initially pain free within a median time of 10 days (range 1-459 days) after GKS. One hundred sixty-nine patients (37.2%) became pain free within the first 48 hours (Group PF(≤ 48 hours)), 194 patients (42.8%) between posttreatment Day 3 and

    Fibroblast strains were derived from 2 regions of the lower genital tract of localized provoked vulvodynia (LPV) cases and pain-free controls. Sixteen strains were derived from 4 cases and 4 controls, age and race matched, after presampling mechanical pain threshold assessments. Strains were challenged with 6 separate stimuli: live yeast species (Candida albicans, Candida glabrata, Candida tropicalis, and Saccharomyces cerevisiae), yeast extract (zymosan), or inactive vehicle. Production of prostaglandin E2 (PGE2) and interleukin 6 (IL-6) were proinflammatory response measures. Highest IL-6 and PGE2 occurred with vestibular strains after C albicans, C glabrata, and zymosan challenges, resulting in the ability to significantly predict IL-6 and PGE2 production by genital tract location. After C albicans and C glabrata challenge of all 16 fibroblast strains, adjusting for dual sampling of subjects, PGE2 and IL-6 production significantly predicted the presampling pain threshold from the genital tract site of sampling. At the same location of pain assessment and fibroblast sampling, in situ immunohistochemical (IHC)(+) fibroblasts for IL-6 and Cox-2 were quantified microscopically. The correlation between IL-6 production and IL-6 IHC(+) was statistically significant; however, biological significance is unknown because of the small number of IHC(+) IL-6 fibroblasts identified. A low fibroblast IL-6 IHC(+) count may result from most IL-6 produced by fibroblasts existing in a secreted extracellular state. Enhanced, site-specific, innate immune responsiveness to yeast pathogens by fibroblasts may be an early step in LPV pathogenesis. Fibroblast strain testing may offer an attractive and objective marker of LPV pathology in women with vulvodynia of inflammatory origin.

    Empirical evidence suggests that affective responses to pain are changed in chronic pain. The investigation of startle responses to pain might contribute to clarifying whether such alterations also expand to motivational defensive reactions. We aimed at comparing startle responses to tonic heat pain with high threat (HT) or low threat (LT) in patients with chronic musculoskeletal pain and controls. As pain-related anxiety and catastrophizing are typically elevated in chronic pain, we expected to find stronger startle responses in patients specifically under experimental HT. Patients with chronic musculoskeletal, preferentially, back pain (N = 19) and matched pain-free controls (N = 19) underwent two pain-related threat conditions (high and low) in balanced order. Only, in the HT condition, 50% of the trials were announced to include a short further noxious temperature increase at the end. Startle responses to loud tones were always assessed prior to a potential temperature increase in the phase of anticipation and were recorded by surface electromyogram. Surprisingly, we observed no differences in startle responses and ratings of emotional and pain responses between patients and controls despite significantly higher pain-related anxiety and catastrophizing in the patients. Overall, startle was potentiated in the HT condition, but only in participants who started with this condition. Our results suggest that, in general, patients with pain are not more responsive emotionally to experimental threat manipulations despite elevated pain anxiety and catastrophizing. Instead, exaggerated responses in patients might be triggered only by individual concerns relating to pain, which are not sufficiently mirrored by our threat paradigm.

    Full Text Available Background: Low back pain is a common, benign, and self-limiting disease that affects almost all persons, with a lifetime prevalence of up to 84%. In contrast, sciatica affects only 40 % of all persons in the Western industrialized countries. In sciatica, pain radiates down the legs, below the knee along the distribution of sciatic nerve. Nerve root compression is the most common cause of sciatica. Neuro dynamics or Neural Tissue Mobilization is relatively new approach in treatment of neuro musculoskeletal disorders. The aim of the study to determine the effectiveness of Neural Tissue mobilization on pain, pain free passive SLR ROM &functional disability in LBA subjects with Sciatica. Objective of the study is to study and compare the effectiveness of Neural tissue mobilization in LBA subjects with sciatica in terms of pain, pain free SLR ROM and Oswestry Disability Index. Methods: 30 subjects were selected by simple random sampling and assigned in to Control(n=15 &Experimental group(n=15.The subjects in control group were given conventional physiotherapy and those in Experimental group were given Neural Tissue Mobilization in addition to conventional therapy. All the participants were assessed with VAS, ODI and pain free passive SLR ROM. Results: After the analysis, the results were found to be significant improvement in pain, pain free SLR ROM, ODI in both groups (p< 0.00.But there is a high significance in Experimental group when compared to control group. Conclusion: Results suggest that NEURAL TISSUE MOBILIZATION along with conventional therapy is more effective in reducing pain, decreasing disability and improving SLR ROM.

    The way individuals attend to pain is known to have a considerable impact on the experience and chronification of pain. One method to assess the habitual "attention to pain" is the Pain Vigilance and Awareness Questionnaire (PVAQ). With the present study, we aimed to test the psychometric properties of the German version of the PVAQ across pain-free samples and across patients with acute and chronic pain. Two samples of pain-free individuals (student sample (N = 255)/non-student sample (N = 362)) and two clinical pain samples (acute pain patients (N = 105)/chronic pain patients (N = 36)) were included in this cross-sectional evaluation of the German PVAQ. Factor structure was assessed using exploratory and confirmatory factor analyses. Reliability was assessed using internal consistency (Cronbach's alpha). Construct validity was tested by assessing correlations between PVAQ and theoretically related constructs. Exploratory factor analysis (non-student sample) and confirmatory factor analysis (student sample, acute pain patient sample) suggested that a two-factor solution best fitted our data ("attention to pain," "attention to changes in pain"). Internal consistency ranged from acceptable to good in all four samples. As hypothesized, the PVAQ correlated significantly with theoretically related constructs in all four samples, suggesting good construct validity in pain-free individuals and in pain patients. The German PVAQ shows good psychometric properties across samples of pain-free individuals and patients suffering from pain that are comparable to PVAQ versions of other languages. Thus, the German PVAQ seems to be a measure of pain vigilance equally valid as found in other countries.

    To examine the role of 'student-to-student local analgesia administration' on undergraduate dental students' opinions regarding pain-free local analgesia techniques in children. Grade 3 (n:29), Grade 4 (n:59) and Grade 5 students (n:28) of Yeditepe University, School of Dentistry, Istanbul, Turkey participated in the study. Informed consent and ethical approval were obtained. Students' opinions were evaluated by means of a short survey administered before and after educational activities. Activities were provided in a didactic manner (theoretical, practical and clinical stages) and lasted for 6 months. Theoretical lectures on 'pain-free local analgesia techniques in children' were given to all classes. In the practical stage, 3rd and 4th grade students were paired and performed infiltration analgesia on each other according to the lectured technique. In the final clinical stage, 4th and 5th grade students were supervised, whilst administering the technique on children during their clinical training. Before the activities, only 40% of students believed in the possibility of pain-free local analgesia in children, whereas after the educational activities, the percentage had risen to 68% (P = 0.0001). A significant difference was observed between the opinions of 4th grade students who attended the practical stage and 5th grade students who did not. The role of 'student-to-student local analgesia administration' was found to be significant in changing undergraduate students' opinions about pain-free dental injections in children. © 2013 John Wiley & Sons A/S.

    While there is limited evidence supporting the use of soft tissue mobilization techniques for Subacromial Pain Syndrome (SAPS), synonymous with subacromial impingement syndrome, previous studies have reported successful outcomes using soft tissue mobilization as a treatment technique. The purpose of this case report is to document the results of Instrument-Assisted Soft Tissue Mobilization (IASTM) for the treatment of SAPS. Diagnosis was reached based on the subject's history, tenderness to palpation, and four out of five positive tests in the diagnostic cluster. Treatment consisted of three visits where the IASTM technique was applied to the pectoral muscles as well as periscapular musculature followed by retesting pain-free shoulder flexion active range of motion (AROM) and Numerical Pain Rating Scale (NPRS) during active shoulder flexion. Scapulothoracic mobilization and stretching were performed after AROM measurement. The subject reported an NPRS of 0/10 and demonstrated improvements in pain free flexion AROM in each of the three treatment sessions post-IASTM: 85 ° to 181 °, 110 ° to 171 °, and 163 ° to 174 ° with some carryover in pain reduction and pain free AROM to the next treatment. Through three treatments, DASH score improved by 17.34%, Penn Shoulder Score improved 29%, worst NPRS decreased from 4/10 to 0/10, and a GROC score of 6. IASTM may have a beneficial acute effect on pain free shoulder flexion. In conjunction with scapulothoracic mobilizations and stretching, IASTM may improve function, decrease pain, and improve patient satisfaction. While this technique will not ameliorate the underlying pathomechanics contributing to SAPS, it may serve as a valuable tool to restore ROM and decrease pain allowing the patient to reap the full benefits of a multi-modal treatment approach. 5.

    Chronic pain may result both from a generalized hypersensitivity to acute pain, suggestive of central sensitization processes, and dysfunction of the endogenous pain regulatory system. One purpose of this study was to compare experimental pain sensitivity at several anatomic sites in temporomandibular disorder (TMD) patients and pain-free controls during baseline and after standardized mechanical load of the orofacial region. A second purpose was to compare the pain-modulating effects of cardiovascular responses in TMD patients and pain-free controls. Experimental pain was induced by electrocutaneous stimulation of the dorsal left hand and pressure algometry at the right masseter muscle and the sternum. The pain sensitivity of the orofacial region was manipulated by isometric contraction of the masseter muscles. Elevations of mean arterial pressure and heart rate were induced by a simulated job interview. At baseline, the TMD patients exhibited a significantly higher electrocutaneous pain threshold. Relative to the healthy controls, the TMD patients reported increased electrocutaneous and pressure pain sensitivity after isometric contraction of the orofacial region. In addition, there were correlations between mean arterial pressure and pain sensitivity in the TMD group only. Significant increases in generalized pain sensitivity occurred in the TMD group, but not in the control group, after isometric contraction of the orofacial muscles, suggestive of a central sensitization process in TMD. Moreover, only in the TMD group there were significant associations between cardiovascular responsesand pain sensitivity, challenging previous assumptions of this relationship occurring mainly in pain-free individuals.

    The objective of this study was to examine, in individuals with lateral epicondylalgia (LE), the acute time course of acupuncture-induced hypoalgesia and change in pain-free grip strength (PFGS). This was an experimental study, conducted at a single research center in Vancouver, BC. Twenty-one participants with unilateral LE lasting more than 6 weeks duration were enrolled. Participants received a single treatment of acupuncture (either electroacupuncture, 10-30 Hz, or manual acupuncture, assigned randomly). The primary outcome measure was pain level (0-10) during tendon loading (while making a fist) immediately after treatment, and over a 72 h follow-up period. Secondary outcome measures included pain-free grip strength (N). There was a small but statistically significant reduction in participants' perceived pain level immediately after acupuncture (mean improvement of 1.2, 95% CI 0.45-1.9). This change in pain was not accompanied by a change in PFGS. No difference was observed between the two types of acupuncture at any time point. The use of acupuncture or electroacupuncture, as administered in the current study, is unlikely to acutely enhance the ability of people with LE to engage in pain-free rehabilitation exercise.

    Tooth clenching has been suggested to be related to temporomandibular pain. However, the electromyographic characteristics of daytime clenching episodes have been minimally investigated. This study aimed to analyze the frequency, amplitude, and duration of daytime clenching episodes in patients with masticatory muscle pain and pain-free individuals. Fifteen women with masticatory muscles myalgia (MP group, mean ± SD age = 26.4 ± 7.6 years) matched for age to 18 pain-free women (CTR group, mean ± SD age = 25.3 ± 2.8 years) were submitted to three different ability tasks (filling out questionnaires for 40 min, reading for 20 min, and playing a videogame for 20 min). The electromyographic activity periods (AP) of the right masseter greater than 10 % (AP10), 20 % (AP20), and 30 % (AP30) of the maximum voluntary contraction were analyzed. The mean frequencies of AP10, AP20, and AP30 were greater in MP than in CTR individuals (all p pain-free individuals. Clinicians should recognize that the frequency and intensity of daytime clenching are noticeably increased in individuals with masticatory muscle pain in order to better tailor treatment.

    Advances in sunscreen technologies have yielded broad spectrum sunscreens at high-sun protection factor (SPF) and ultraviolet A protection factor (UVA-PF) levels that are photostable and powerful in protecting skin from erythema. Questions arise whether these sunscreens protect proportionally against cellular skin damage caused by high ultraviolet exposures. The objective of this study is to evaluate if high-SPF sunscreen can protect skin at a cellular level under UV exposure doses [>50 minimal erythema dose (MED)] similarly to the SPF value. Sunburn cells, Langerhans cells, thymine dimers, protein 53 (p53), and matrix metalloproteinase (MMP)-1 and MMP-9 endpoints were evaluated in biopsies from 12 subjects following four treatments: unprotected exposed to 0, 1 and 3 MED and sunscreen (SPF 55) protected exposed to 55 MED of UV radiation. All the markers showed significantly more damage for the 3 MED-untreated sites when compared with non-irradiated control, and majority of the markers showed marked damage following unprotected 1 MED exposure. After 55 MEDs, sunscreen-protected sites showed significantly less p53 and MMP-9 (keratinocyte) staining than the 1 MED-exposed unprotected sites, while all the other biomarkers in sunscreen protected sites showed no statistical differences from 1 MED-exposed unprotected sites. A high-SPF photostable sunscreen with high UVA-PF can provide proportionately high protection against multiple cellular damage markers. © 2014 John Wiley & Sons A/S.

    To investigate the differential nature of disturbed sleep in patients with fibromyalgia (FM) reporting sleep difficulties versus patients with primary insomnia (PI) and patients who do not report disturbed sleep (pain-free controls). Patients (FM: n=132; PI: n=109; normals: n=52) were recruited for different studies. FM and PI patients were preselected to meet the sleep disturbance criteria. Patients with sleep or circadian disorders were excluded from all groups. Polysomnography was conducted at screening, during 2 consecutive nights. For this post hoc analysis of polysomnographies, length and frequency (duration, number) of wake and sleep bouts were analyzed, together with traditional sleep measures; a "bout"=consecutive 30-second epochs of sleep or wake. Data are mean±SD. FM and PI patients had decreased total sleep time and slow-wave sleep (SWS), and increased latency to persistent sleep (LPS) and wake time after sleep onset (WASO) versus controls (P<0.05 for each). FM versus PI patients had more SWS (48.1±32.4 vs. 27.2±23.6 min; P<0.0001) and shorter LPS (58.2±29.8 vs. 70.7±31.3 min; P=0.0055), but comparable WASO (107.7±32.8 vs. 108.6±31.5 min). Despite comparable WASO, FM patients had shorter (4.64±2.42 vs. 5.87±3.15 min; P=0.0016) but more frequent wake bouts versus PI patients (41.6±16.7 vs. 35.7±12.6; P=0.0075). Sleep bout duration was similar for FM (9.32±0.35 min) and PI patients (10.1±0.37 min); both populations had shorter sleep bout duration versus controls (15.7±0.7 min; P<0.0001 both). Increased frequency of wake and sleep bouts and decreased wake bout duration, together with decreased LPS and increased SWS, suggests that sleep in FM is characterized by an inability to maintain continuous sleep but a greater sleep drive compared with PI.

    The first objective of this study is to show how different can be photoprotection by sunscreens with an identical SPF given on the packaging, when subjected to sunlight radiation. The second objective is to highlight the need for global harmonization of photostability testing and UVA protection labelling. Fifteen products with various combinations of UV filters marketed in Europe were assessed based on transmission measurements of 0.75 mg cm⁻² layer covered onto polymethylmethacrylate plate roughness 2 μm. Two absolute UV spectroscopic indices (in vitro SPF, UVA-PF), four well-known relative UVA indices: the UVA-PF/SPF ratio and critical wavelength by European Commission (EC); UVA/UVB ratio by Boots Star Rating system; UVA1/UV ratio by FDA Proposed Ruling and one new relative indices the Spectral Uniformity Index (SUI) by Diffey, were compared before and after sunlight exposure with dose about 42 SEDs. The UVA-PF values before exposure proved a high degree of variation among samples. After exposure only five sunscreens observed UVA protection standard by EC and the same products showed compliance with the first UVA rating by Boots system (three stars). According to the UVA1/UV ratio, except for one product, all sunscreens manifested certain UVA protection level (low, medium or high). In compliance with criteria of new rating proposed by Diffey, exactly all fifteen sunscreens gave some UVA rating exhibited as SUI (low, medium or high). These results mean that the different UVA protection indices can exhibit various data and be confusing for consumer. Photostability of each product was assessed with three indices: the area under curve (Auc) Index for the total UV range, and UVB, UVA, UVA2, UVA1 range separately; the residual effectiveness of in vitro SPF and UVA-PF. All fifteen sunscreens were photostable in the UVB region. Seven products exhibited photoinstability in the total UV range (290-400 nm); all of them contained a combination of the ethylhexyl

    The purpose of this study was to determine the patterns of lumbopelvic motion and erector spinae (ES) activity during trunk flexion-extension movements and to compare these patterns between patients with recurrent low back pain (LBP) in their pain-free periods and matched asymptomatic subjects. Thirty subjects participated (15 patients with disc herniation and recurrent LBP in their pain-free periods and 15 asymptomatic control subjects). A 3-dimensional videophotogrammetric system and surface electromyography (EMG) were used to record the angular displacements of the lumbar spine and hip in the sagittal plane and the EMG activity of the ES during standardized trunk flexion-extension cycles. Variables were maximum ranges of spine and hip flexion; percentages of maximum lumbar and hip flexion at the start and end of ES relaxation; average percentages of EMG activity during flexion, relaxation, and extension; and flexion-extension ratio of myoelectrical activity. Recurrent LBP patients during their pain-free period showed significantly greater ES activation both in flexion and extension, with a higher flexion-extension ratio than controls. Maximum ranges of lumbar and hip flexion showed no differences between controls and patients, although patients spent less time with their lumbar spine maximally flexed. This study showed that reduced maximum ranges of motion and absence of ES flexion-relaxation phenomenon were not useful to identify LBP patients in the absence of acute pain. However, these patients showed subtle alterations of their lumbopelvic motion and ES activity patterns, which may have important clinical implications.

    Case control study including 2 groups of patients with low back pain (LBP, inflammatory and noninflammatory) and a pain-free community control group. We explored whether pain beliefs differ between patients with chronic LBP attributed to inflammatory or noninflammatory medical diagnoses, and between patients with chronic LBP and pain-free controls. Beliefs strongly influence patients' engagement in and response to treatments for chronic LBP. It is unclear, however, whether unhelpful beliefs held by patients with chronic LBP are predominantly associated with diagnosis, or with other aspects of the patient's pain experience. Patients and controls completed the pain beliefs questionnaire addressing beliefs about the causes and consequences of pain. Patients also completed questionnaires addressing catastrophizing (Coping Strategies Questionnaire), physical disability and bodily pain (SF-36 Health Survey), and psychological distress (Spielberger State-Trait Anxiety Inventory Short Form and Cognitive Depression Index). Variance analysis and chi2 test were used as appropriate, adjusting for effects of covariates and multiple comparisons. Linear regression and logistic regression were used to adjust for confounding factors. Patients with noninflammatory LBP more strongly endorsed organic pain beliefs (e.g., that pain necessarily indicates damage), and catastrophizing (e.g., that the pain is never going to get better), than did patients with inflammatory LBP (P pain-free controls (P < 0.05). Endorsement of organic pain beliefs was associated with catastrophizing. Organic pain beliefs are associated with increased catastrophizing in patients with chronic LBP, and addressing these beliefs may help patients to manage their pain and disability. Meanings attributed to inflammatory and noninflammatory diagnostic labels may contribute to the different pain beliefs held by different patient groups.

    Full Text Available Abstract Introduction The use of automated text messages has made it possible to identify different courses of low back pain (LBP, and it has been observed that pain often fluctuates and that absolute recovery is rather rare. The purpose of this study was to describe the prevalence of pain-free weeks and pain-free periods in subjects with non-specific LBP treated by chiropractors, and to compare subjects from two different countries in these aspects. Methods Data were obtained from two practice-based multicentre prospective outcome studies, one Danish and one Swedish, involving subjects being treated by chiropractors for non-specific LBP. Over 18 weeks, subjects answered a weekly automated text message question on the number of days in the past week that they had experienced bothersome LBP, i.e. a number between 0 and 7. The number of weeks in a row without any LBP at all ("zero weeks" as well as the maximum number of zero weeks in a row was determined for each individual. Comparisons were made between the two study samples. Estimates are presented as percentages with 95% confidence intervals. Results In the Danish and the Swedish populations respectively, 93/110 (85% and 233/262 (89% of the subjects were eligible for analysis. In both groups, zero weeks were rather rare and were most commonly (in 40% of the zero weeks reported as a single isolated week. The prevalence of pain free periods, i.e. reporting a maximum of 0, 1 or 2, or 3-6 zero weeks in a row, were similar in the two populations (20-31%. Smaller percentages were reported for ≥ 7 zero weeks in a row. There were no significant differences between the two study groups. Conclusion It was uncommon that chiropractic subjects treated for non-specific LBP experienced an entire week without any LBP at all over 18 weeks. When this occurred, it was most commonly reported for brief periods only. Hence, recovery in the sense that patients become absolutely pain free is rare, even in a primary

    Total ion yield spectra of PF 3, PCl 3, PCl 2CF 3, OPF 3 and SPF 3 were recorded in the region of P 2p, P 2s, S 2p, S 2s and halogen (Cl 2p, F 1s) excitation using synchrotron radiation. The P 2p spectra are interpreted with GSCF3 ab initio configuration interaction calculations optimized for core excitation studies. The experimental-theoretical comparison is based on both absolute intensities (oscillator strengths) and transition energies. The calculations indicate that several of the discrete states (e.g., that in PF 3 at 136.5 eV) are best described as LS-coupled states because the core-valence electron exchange is very large and thus the singlet-triplet splitting is larger than the spin-orbit splitting. While the state at 136.5 eV in PF 3 is particularly notable, analogous P 2p excited states with large singlet-triplet splittings are calculated in PCl 3, PCl 2CF 3, OPF 3 and SPF 3. Aspects of partial ion yield measurements (particularly the PF 3+ yield of PF 3 and the SPF 3+ yield of SPF 3) support this interpretation by revealing isolated single states without a corresponding partner at the spin-orbit splitting. The partial ion yields help clarify spectral interpretation by removing interference from overlap with adjacent states having the normal ( j, j)-coupled ion core character.

    Skin care products (cleansers and moisturizers) to complement benzoyl peroxide (BPO) in the treatment of acne may improve treatment tolerability and adherence. Evaluate subject satisfaction after use of BPO 5% gel in combination with liquid cleanser and moisturizer SPF 30. Open-label study including subjects aged ≥12 years with mild-to-moderate facial acne; ClinicalTrials.gov Identifier: NCT02589405. Once daily BPO 5% gel, twice daily liquid cleanser and once daily moisturizer SPF 30 were applied for 12 weeks. Assessments included a subject satisfaction questionnaire, investigator global assessment of improvement, lesion counts, the presence of Propionibacterium acnes, and safety. Fifty subjects were enrolled. Most subjects were overall satisfied with the three-part regimen (87%) and felt better about themselves (94%). Subjects indicated the skin care products helped prepare the skin for treatment (85%), relieve itchy skin (81%) and reduce irritation (87%). Most subjects considered that the liquid cleanser (80%) and moisturizer SPF 30 (84%) were a necessary part of acne treatment. BPO reduced P. acnes load by 89% at week 1. The treatment was well tolerated. The combination of BPO 5% gel with liquid cleanser and moisturizer SPF 30 resulted in high levels of subject satisfaction, good tolerability and treatment adherence.

    The fear-avoidance model implies that in situations with physical demands patients with back pain will overestimate the demand and underestimate their own capacities. A total of 71 patients with back pain and 48 pain-free control subjects carried out a standardized lifting test with a preceding estimation of their lifting capacity. In both groups the self-estimation and real lifting capacity were in concordance for most group members with patients showing less disconcordance than controls. In the control group 35% of the subjects even underestimated their lifting capacity, which was the case in only 14% of the patients. Patients more frequently overestimated their capacity than pain-free controls (14% vs. 2%). Within the patients subgroups could be identified where patients in general either underestimated or overestimated their own capacity. A comparison between the groups demonstrated significant differences in pain intensity, fear avoidance beliefs and effort. As an explanation for these unexpected results it can be hypothesized that in cases of back pain, patients' attention is focused on pain-relevant issues which enables a more realistic estimation of their lifting capacity.

    In the past decade, biological nurturing and activation of maternal and infant instincts after birth have constituted a major advance in clinical breastfeeding support. Yet, physiologic breastfeeding initiation is not enough to ensure ongoing pain-free and effective breastfeeding for many pairs. Current interventions, including "hands-off" mammalian approaches, do not improve breastfeeding outcomes, including in randomized controlled trials. Back-arching, difficulty latching or staying on the breast, and fussing at the breast are common signs of infant positional instability during breastfeeding. These cues are, however, often misdiagnosed as signs of medical conditions or oral connective tissue abnormalities, and underlying positional instability is not addressed. New clinical approaches are urgently required. This article offers a clinical approach to fit and hold (or latch and positioning)- gestalt breastfeeding, which aims to optimize positional stability and intraoral breast tissue volumes for pain-free effective breastfeeding. The word gestalt (pronounced "ger-shtolt") means a whole that is more than the sum of its parts. Gestalt breastfeeding builds on the theoretical foundations of complexity science, physiologic breastfeeding initiation, and new understandings of the biomechanics of infant suck elucidated in ultrasound studies. It also integrates simple psychological strategies from applied functional contextualism, popularly known as Acceptance and Commitment Therapy, empowering women to attend mindfully to breast sensations and their infant's cues. Gestalt breastfeeding can be reproduced for research purposes, including in comparison studies with oral surgery, and has the potential to improve breastfeeding outcomes.

    Quantitative sensory testing (QST) has been used to elucidate the peripheral and central mechanisms that underlie changes in pain sensitivity associated with low back pain (LBP). However, it remains unclear to what degree peripheral and central changes contribute to the generation and maintenance of LBP. The aim of this study was to compare thermal pain sensitivity, measured using QST, in participants with acute LBP, chronic LBP, and pain-free controls. Participant groups with acute LBP (N=20), chronic LBP (N=30), and pain-free controls (N=30) were assessed by thermal QST. The unique contributions of pain-related psychological and QST variables to predict membership to the acute and chronic pain groups were also determined. We found that participants with chronic LBP demonstrated significantly lower cold pain threshold (CPT) in the primary area of pain (low back) as well as in an area anatomically remote from the primary area of pain (forearm) when compared with controls. Participants with acute LBP did not show significantly elevated pain sensitivity. CPT at the remote site was a significant independent predictor of membership to the chronic pain group, after the adjustment for mood and pain catastrophizing. CPT explained 8% of the total variance of 46% related to group membership. We found evidence for localized and generalized cold hyperalgesia in chronic, but not acute LBP. We might speculate that hyperalgesia develops as a consequence of long-lasting LBP, but prospective studies are needed to confirm this assumption.

    Evaluation of reliability of isometric strength measurements in the neck and trunk region and comparison of these measurements between patients with chronic neck pain and pain-free subjects. Nonrandomized controlled trial. Institutional practice. Patients with neck pain (n=53) and pain-free persons (n=42) (mean age ± SD, 49.7±10.74 vs 48.7±12.02; women, 73% vs 71%). Strength of flexion, extension, and lateral flexion in the neck and trunk were measured. Each participant underwent 2 measurement passes on each of 2 examination days; 3 were performed by the same investigator, 1 by a second. Intrarater (short-term and long-term) and interrater reliability, differences in strength between both groups of probands. Reliability in both groups ranged from substantial to almost perfect (intraclass correlation coefficient: patients, .76-.89; control group, .80-.88). The patients' strength in the neck and trunk was significantly below that of the control group (P<.002). Isometric strength measurement is a reliable and feasible way to estimate the possible benefit of specific strengthening programs. Patients with chronic neck pain showed strength deficits in all measured regions. Copyright © 2010 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

    Lumbar flexion-relaxation (FR) is a well-known phenomenon that can reliably be seen in normal subjects but not in most chronic low back pain (CLBP) patients. The purpose of this study was to determine which surface electromyographic (SEMG) measures of FR best distinguish CLBP patients from pain-free control subjects. Standing SEMG and lumbar flexion range of motion (ROM) were also evaluated. A cohort of 218 CLBP patients, who were admitted to a functional restoration program, received a standardized SEMG and ROM assessment during standing trunk flexion and reextension. An asymptomatic control group of 30 nonpatients received an identical assessment. Both groups were compared on 8 separate SEMG and 3 flexion ROM measures. A receiver operating characteristic curve analysis was used to determine how well each measure distinguished between the CLBP patients and the pain-free control subjects. All SEMG measures of FR performed acceptably. Between 79% and 82% of patients, and 83% and 100% of controls were correctly classified. Standing SEMG performed less well. Gross flexion ROM was the best single classification measure tested, correctly classifying 88% of patients and 83% of controls. A series of discriminant analyses found that certain combinations of SEMG and ROM performed slightly better than gross ROM alone for correctly classifying the 2 subjects groups. Because all SEMG measures of FR performed acceptably, the determination of which SEMG measure of FR is "best" is largely dependent on one's specific purpose. In addition, ROM measures were found to be important components of the FR assessment.

    Investigating the brain of migraine patients in the pain-free interval may shed light on the basic cerebral abnormality of migraine, in other words, the liability of the brain to generate migraine attacks from time to time. Twenty unmedicated "migraine without aura" patients and a matched group of healthy controls were investigated in this explorative study. 19-channel EEG was recorded against the linked ears reference and was on-line digitized. 60 x 2-s epochs of eyes-closed, waking-relaxed activity were subjected to spectral analysis and a source localization method, low resolution electromagnetic tomography (LORETA). Absolute power was computed for 19 electrodes and four frequency bands (delta: 1.5-3.5 Hz, theta: 4.0-7.5 Hz, alpha: 8.0-12.5 Hz, beta: 13.0-25.0 Hz). LORETA "activity" (=current source density, ampers/meters squared) was computed for 2394 voxels and the above specified frequency bands. Group comparison was carried out for the specified quantitative EEG variables. Activity in the two groups was compared on a voxel-by-voxel basis for each frequency band. Statistically significant (uncorrected P pain-free interval and might be suitable for planning forthcoming investigations.

    Aberrant circadian rest/activity rhythms (RARs) may promote poor aging-related health outcomes. Osteoarthritis and chronic insomnia are common age-related conditions, but the circadian RARs of each group have not been well characterized or compared. We evaluated actigraphic RARs in individuals with: (1) knee osteoarthritis (KOA) only; (2) chronic insomnia only; (3) KOA + insomnia; and (4) pain-free good sleepers. Compared to participants with KOA only, those with KOA + insomnia had less robust RARs. There were no differences between other groups. Further research is needed to evaluate whether aberrant RARs contribute to arthritis symptoms and insomnia in KOA, and whether strengthening RARs ameliorates arthritis symptoms.

    Implantable cardioverter defibrillator (ICD) shock therapy improves survival of patients at risk for sudden cardiac death. The high sensitivity of ICDs to detect tachycardia events is accompanied by reduced specificity resulting in inappropriate and unnecessary shocks. Up to 30% of ICD patients may experience inappropriate shocks, which are most commonly caused by lead noise, oversensing of T-waves, and supraventricular tachycardias. The new Protecta ICD and cardiac resynchronization therapy devices have been designed to minimize inappropriate and unnecessary shocks through novel SmartShock(TM) technology algorithms targeting these causes. The PainFree SST study is a prospective, multicentre clinical trial, which will be conducted in two consecutive phases. Phase I will assess safety and any delay that may arise in ventricular fibrillation (VF) arrhythmia detection time using new algorithms. Phase II will evaluate reduction of inappropriate and unnecessary shocks at 1 year of follow-up. Additional objectives will include Quality of Life, healthcare utilization, safety of extending the ventricular tachyarrhythmia/VF interval detection duration (18 out of 24 vs. 30 out of 40 intervals), and reasons for inappropriate shock. Up to 2000 subjects in 150 centres worldwide will be enrolled with a follow-up of at least 1 year. Subjects enrolled in Phase I will continue in Phase II of the study and data from all enrolled subjects will contribute to the analysis of Phase II objectives. Inappropriate and unnecessary shock delivery remains a significant clinical issue for patients receiving device therapies, which has considerable consequences for patients and the healthcare system. The PainFree SST study will investigate the ability of new algorithms to reduce inappropriate shocks. Results from this study are expected in mid-2013.

    Some normotensive patients can have a spike in resting systolic blood pressure (SBP) in response to acute neck pain. Applying the typical dosage of mobilization may potentially result in a sympatho-excitatory response, further increasing resting SBP. Therefore, there is a need to explore other dosage regimens that could result in a decrease in SBP. To compare the blood pressure (BP) and heart rate (HR) response of pain-free, normotensive adults when receiving unilateral posterior-to-anterior mobilization (PA) applied to the neck versus its corresponding placebo (PA-P). Double-Blind, Randomized Clinical Trial. 44 (18 females) healthy, pain-free participants (mean age, 23.8 ± 3.04 years) were randomly allocated to 1 of 2 groups. Group 1 received a PA-P in which light touch was applied to the right 6th cervical vertebra. Group 2 received a PA to the same location. BP and HR were measured prior to, during, and after the application of PA or PA-P. A mixed-effect model of repeated measure analysis was used for statistical analysis. During-intervention, the PA group had a significant reduction in SBP, while the placebo group had an increase in SBP. The change in SBP during-intervention was significantly different between the PA and the placebo group (p-value = 0.003). There were no significant between-group differences found for HR and diastolic BP (DBP). The overall group-by-time interaction was statistically significant for SBP (p-value = 0.01). When compared to placebo, the dosage of applied PA resulted in a small, short-lived drop in SBP not exceeding the minimal detectable change. Trial registered at Germanctr.de (DRKS00005095).

    Descending pain inhibition is an endogenous pain control system thought to depend partially on the activation of bulbospinal monoaminergic pathways. Deficits in descending pain inhibition have been reported in numerous human chronic pain conditions, but there is currently no consensus regarding the neurochemical correlates responsible for this deficit. The aims of this study were to 1) assess the efficacy of descending pain inhibition in pain-free and chronic pain subjects, 2) screen for changes in centrally (ie, cerebrospinal fluid) and peripherally (ie, plasma) acting monoamine concentrations, and 3) explore the relationship between descending pain inhibition and monoamine neurotransmitter concentrations. Our results clearly show a deficit in pain inhibition, along with lower plasma norepinephrine and metanephrine concentrations in chronic pain subjects, compared to pain-free subjects. No differences were found in cerebrospinal fluid neurotransmitter concentrations. Finally, our results revealed a positive relationship between blood-bound norepinephrine and metanephrine concentrations and the efficacy of descending pain inhibition. Thus, basal monoamine levels in blood were related to descending pain inhibition. This finding supports the emerging idea that individual differences in descending pain inhibition may be linked to individual differences in peripheral processes, such as monoamines release in blood, which are possibly related to cardiovascular control. This article presents psychophysical and neurochemical findings that indicate that the latent potential of descending pain inhibitory responses is associated with differential activity in peripheral processes governed by monoamine neurotransmitter release, bringing insights into the relationship between descending pain inhibition and cardiovascular control in humans.

    Several studies documented abnormal nociceptive processing in PD patients. Pain central pathways are accessible by laser-evoked potentials (LEPs). LEPs recording show a N2/P2 complex mostly generated by the anterior cingulate cortex, preceded by an earlier negative component (N1), originating from the opercular cortex. Previous work demonstrated N2/P2 amplitude reduction in PD patients and suggested a centrally-acting pathomechanism for the genesis of pain. However, since a peripheral deafferentation has been recently demonstrated in PD, it is not clear if such LEP abnormalities reflect a mechanism acting centrally or not. To assess whether abnormalities of nociceptive inputs occur at central and/or peripheral level in pain-free PD patients with hemiparkinson using Nd:YAP LEPs. We recorded scalp Nd:YAP-LEPs to hand stimulation in 13 pain-free patients with unilateral PD and in 13 healthy subjects. Additionally, we collected laser pain-rating in both groups. PD patients and normal subjects showed comparable N1, N2 and P2 latencies. The N2/P2 amplitude was significantly lower in PD patients than in controls, regardless of the clinically affected side, whereas the N1/P1 amplitude was not different. PD patients had higher pain-rating, indicative of hyperalgesia. These findings demonstrate that in the PD patients the abnormal processing of pain stimuli occurs at central rather than peripheral level. The co-existence of hyperalgesia and reduced amplitude of the N2/P2 complex, in spite of a normal N1/P1 component, suggests an imbalance between the medial and lateral pain systems. Such a dissociation might explain the genesis of central pain in PD. Copyright © 2016. Published by Elsevier Ltd.

    The SPf66 synthetic malaria vaccine, developed and obtained almost 2 decades ago, represents the first approach towards developing a multi-antigenic, multi-stage synthetic malarial vaccine composed of subunits derived from different Plasmodium falciparum stage proteins. It is shown here that batches 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15 and 16 produced from a few milligrams to kilogram amounts and used in assays on monkeys and humans showed high reproducibility in physicochemical analysis. (1)H NMR two-dimensional studies also revealed high similarity, even in non-oxidized batches. Reproducibility was also high, especially in preclinical studies carried out on Aotus, clinical trials Phase I, IIa and IIb and field-studies carried out in La Tola, Rio Rosario (Colombia), Majadas (Venezuela), La Te (Ecuador), Ifakara (Tanzania) in which there was high antibody titer production, having similar population distribution when done with different batches. These results provide great support for peptide-synthesized vaccines containing minimal epitopes from protection-inducing antigens which have several advantages, such as low cost, safety, reproducibility, stability, being straightforwardly scaled-up from milligram to kilogram amounts; make them the vaccines of choice for the future in a worldwide attempt to scourge diseases such as malaria.

    Using post-larvae derived from specific pathogen free (SPF) stocks in penaeid shrimp farming has led to a dramatic increase in production. At the same time, new pathogens of farmed shrimp are continually being discovered. Sometimes these pathogens are carried by shrimp and other crustaceans as persistent infections without gross signs of disease. Thus it is that a 5-generation stock of Penaeus monodon SPF for several pathogens was found, post-stock-development, to be persistently-infected with newly-discovered Laem Singh virus (LSNV). In this situation, the stock developers were faced with destroying their existing stock (developed over a long period at considerable cost) and starting the whole stock development process anew in order to add LSNV to its SPF list. As an alternative, it was hypothesized that injection of complementary dsRNA into viral-infected broodstock prior to mating might inhibit replication of the target virus sufficiently to reduce or eliminate its transmission to their offspring. Subsequent selection of uninfected offspring would allow for post-clearing of LSNV from the existing stock and for conversion of the stock to LSNV-free status. Testing this hypothesis using the LSNV-infected stock described above, we found that transmission was substantially reduced in several treated broodstock compared to much higher transmission in buffer-injected broodstock. Based on these results, the model is proposed for post-clearing of SPF stocks using dsRNA treatment. The model may also be applicable to post-clearing of exceptional, individual performers from grow-out ponds for return to a nucleus breeding center. Copyright © 2017 Elsevier B.V.

    The conserved NineTeen protein complex (NTC) is an integral subunit of the spliceosome and required for intron removal during pre-mRNA splicing. The complex associates with the spliceosome and participates in the regulation of conformational changes of core spliceosomal components, stabilizing RNA-RNA- as well as RNA-protein interactions. In addition, the NTC is involved in cell cycle checkpoint control, response to DNA damage, as well as formation and export of mRNP-particles. We have identified the Num1 protein as the homologue of SPF27, one of NTC core components, in the basidiomycetous fungus Ustilago maydis. Num1 is required for polarized growth of the fungal hyphae, and, in line with the described NTC functions, the num1 mutation affects the cell cycle and cell division. The num1 deletion influences splicing in U. maydis on a global scale, as RNA-Seq analysis revealed increased intron retention rates. Surprisingly, we identified in a screen for Num1 interacting proteins not only NTC core components as Prp19 and Cef1, but several proteins with putative functions during vesicle-mediated transport processes. Among others, Num1 interacts with the motor protein Kin1 in the cytoplasm. Similar phenotypes with respect to filamentous and polar growth, vacuolar morphology, as well as the motility of early endosomes corroborate the genetic interaction between Num1 and Kin1. Our data implicate a previously unidentified connection between a component of the splicing machinery and cytoplasmic transport processes. As the num1 deletion also affects cytoplasmic mRNA transport, the protein may constitute a novel functional interconnection between the two disparate processes of splicing and trafficking.

    Community coalitions are a prominent organizational structure through which community-based substance abuse prevention efforts are implemented. There is little empirical evidence, however, regarding the association between coalition attributes and success in achieving community-level reductions in substance abuse behaviors. In this study, we assessed the relationship between coalition capacity, based on coalition coordinator responses to 16 survey items, and reductions in underage drinking prevalence rates. The coalitions were funded through the federally sponsored Strategic Prevention Framework State Incentive Grant (SPF SIG). We first examined whether coalition capacity increased over the life of the projects. Mean capacity scores increased for all 16 capacity items examined (N = 318 coalitions), the majority of which were statistically significant. Analysis of the associations between capacity and reductions in underage drinking was limited to coalitions that targeted underage drinking and provided usable outcome measures based on student survey data for either past 30-day alcohol use (N = 129) or binge drinking (N = 100). Bivariate associations between the capacity items and prevalence reductions for each outcome were consistently positive, although many were not statistically significant. Composite measures of correlated items were then created to represent six different capacity constructs, and included in multivariate models to predict reductions in the targeted outcomes. Constructs that significantly predicted reductions in one or both outcome measures included internal organization and structure, community connections and outreach, and funding from multiple sources. The findings provide support for the expectation that high functioning community coalitions can be effective agents for producing desirable community-level changes in targeted substance abuse behaviors.

    Monthly primary dysmenorrhoeic pain is associated with increased sensitivity to painful stimuli, particularly in deep tissue. We investigated whether women with dysmenorrhoea, compared with controls, have increased sensitivity to experimentally induced deep-tissue muscle ischaemia in a body area distant from that of referred menstrual pain. The sub-maximal effort tourniquet test was used to induce forearm ischaemia in 11 women with severe dysmenorrhoea and in nine control women both during menstruation and in the follicular phase of the menstrual cycle. Von Frey hair assessments confirmed the presence of experimental ischaemia. Women rated the intensity of menstrual and ischaemic pain on a 100-mm visual analogue scale. Women with dysmenorrhoea [mean (SD): 68 (20) mm] reported significantly greater menstrual pain compared with controls [mean (SD): 2 (6) mm; p = 0.0001] during the menstruation phase. They also rated their forearm ischaemic pain as significantly greater than the controls during the menstruation [dysmenorrhoeics vs. controls mean (SD): 58 (19) mm vs. 31 (21) mm, p menstruation phase and pain-free follicular phase. These findings suggest the presence of long-lasting changes in muscle pain sensitivity in women with dysmenorrhoea. Our findings that dysmenorrhoeic women are hyperalgesic to a clinically relevant, deep-muscle ischaemic pain in areas outside of referred menstrual pain confirm other studies showing long-lasting changes in pain sensitivity outside of the painful period during menstruation. © 2014 European Pain Federation - EFIC®

    This study aimed to assess the immediate effects on masticatory muscle mechanosensitivity, maximal vertical mouth opening (VMO), and head posture in pain-free healthy participants after intervention with myofascial treatment in the temporalis and masseter muscles. A randomized, double-blind study was conducted. The sample group included 48 participants (n=48), with a mean age of 21±2.47 years (18-29). Two subgroups were defined: an intervention group (n=24), who underwent a fascial induction protocol in the masseter and temporalis muscles, and a control group (n=24), who underwent a sham (placebo) intervention. The pressure pain threshold in 2 locations in the masseter (M1, M2) and temporalis (T1, T2) muscles, maximal VMO, and head posture, by means of the craniovertebral angle, were all measured. Significant improvements were observed in the intragroup comparison in the intervention group for the craniovertebral angle with the participant in seated (P.05). Myofascial induction techniques in the masseter and temporalis muscles show no significant differences in maximal VMO, in the mechanical sensitivity of the masticatory muscles, and in head posture in comparison with a placebo intervention in which the therapist's hands are placed in the temporomandibular joint region without exerting any therapeutic pressure.

    Patients with intermittent claudication due to peripheral arterial disease (PAD) experience muscle aching during walking secondary to ischemia. The purpose of this study was to examine the effects of low-intensity pain-free exercise (LIPFE) on functional capacity of individuals with PAD. A total of 12 participants with PAD underwent training on treadmill for 6 weeks, twice a week, for about 45 minutes. Outcome measures included walking distance (WDI), walking duration (WDU), mean walking rate (WR), estimated oxygen consumption (EVO(2)), metabolic equivalent (MET), estimated total energy expenditure (ETEE), and estimated rate of energy expenditure (EREE). Mean improvement of WDI, WDU, and MWR were 104% (an addition of 1.0 km), 55% (an addition of 13.3 minutes), and 41% (0.9 km/h faster), respectively. Mean improvement of EVO(2), MET, ETEE, and EREE, were 20%, 20%, 80%, and 20%, respectively. In conclusion, it appears that LIPFE training is an effective intervention for individuals presenting with PAD.

    Thigh muscle injuries commonly occur during single leg loading tasks and patterns of muscle activation are thought to contribute to these injuries. The influence trunk and pelvis posture has on hip and thigh muscle activation during single leg stance is unknown and was investigated in a pain free population to determine if changes in body posture result in consistent patterns of changes in muscle activation. Hip and thigh muscle activation patterns were compared in 22 asymptomatic, male subjects (20-45 years old) in paired functionally relevant single leg standing test postures: Anterior vs. Posterior Trunk Sway; Anterior vs. Posterior Pelvic Rotation; Left vs. Right Trunk Shift; and Pelvic Drop vs. Raise. Surface EMG was collected from eight hip and thigh muscles calculating Root Mean Square. EMG was normalized to an "upright standing" reference posture. Repeated measures ANOVA was performed along with associated F tests to determine if there were significant differences in muscle activation between paired test postures. In right leg stance, Anterior Trunk Sway (compared to Posterior Sway) increased activity in posterior sagittal plane muscles, with a concurrent deactivation of anterior sagittal plane muscles (p: 0.016 - <0.001). Lateral hip abductor muscles increased activation during Left Trunk Shift (compared to Right) (p :≤ 0.001). Lateral Pelvic Drop (compared to Raise) decreased activity in hip abductors and increased hamstring, adductor longus and vastus lateralis activity (p: 0.037 - <0.001). Changes in both trunk and pelvic posture during single leg stance generally resulted in large, predictable changes in hip and thigh muscle activation in asymptomatic young males. Changes in trunk position in the sagittal plane and pelvis position in the frontal plane had the greatest effect on muscle activation. Investigation of these activation patterns in clinical populations such as hip and thigh muscle injuries may provide important insights into injury

    Studies have shown that farming is associated with many agricultural workers experiencing low back pain (LBP). The rehabilitation of these workers should facilitate their functioning, activities and level of participation in an adequate way. The objectives of this study were to identify the health components associated with LBP and to evaluate the effectiveness of the interventions in returning agricultural workers with LBP to their vocation using the International Classification of Function (ICF) -based tools. Thirty-one full time agricultural workers from 3 different Indian states were prospectively assessed using the ICF core set for LBP. ICF core sets permitted analysis of limitations of function from both the participant and rehabilitation team's perspectives. Each ICF category was rated using an ICF qualifier. The components identified were linked to the ICF categorical profile and assessment sheet. The clinicians identified the global, service program and cycle goals based on ICF. The participants' functioning was followed over a 4-month period. After intervention, the participants were able to undergo their routine activities without increases in pain. However, on returning to active farming, participants noted few improvements in the components d410 (changing basic body position), d415 (maintaining body position), d430 (lifting and carrying objects), d465 (moving around using equipment), d850 (remunerative employment) and d859 (work and employment, other specified and unspecified). The results of the study conclude that the current interventions for LBP are not effective in returning agriculture workers with LBP in India to pain-free farming. There is an urgent need to individualize the health needs of agriculture workers.

    To assess the potential of a thermal carbon dioxide (CO2) laser to explore antinociception in pain-free cats. Experimental, prospective, blinded, randomized study. Sixty healthy adult female cats with a (mean±standard deviation) weight of 3.3±0.6 kg. Cats were systematically allocated to one of six treatments: saline 0.2 mL per cat; morphine 0.5 mg kg(-1); buprenorphine 20 μg kg(-1); medetomidine 2 μg kg(-1); tramadol 2 mg kg(-1), and ketoprofen 2 mg kg(-1). Latency to respond to thermal stimulation was assessed at baseline and at intervals of 15-30, 30-45, 45-60, 60-75, 90-105 and 120-135 minutes. Thermal thresholds were assessed using time to respond behaviourally to stimulation with a 500 mW CO2 laser. Within-treatment differences in response latency were assessed using Friedman's test. Differences amongst treatments were assessed using independent Kruskal-Wallis tests. Where significant effects were identified, pairwise comparisons were conducted to elucidate the direction of the effect. Cats treated with morphine (χ2=12.90, df=6, p=0.045) and tramadol (χ2=20.28, df=6, p=0.002) showed significant increases in latency to respond. However, subsequent pairwise comparisons indicated that differences in latencies at specific time-points were significant (ppain-free cats after analgesic administration and may provide a simpler alternative to existing systems.

    A two-point discrimination test (TPD) is commonly used to investigate lumbar tactile acuity. However, low inter-examiner reliability and difficulties in execution significantly limit its application. Therefore the aim of this study was to compare the inter- and intra-examiner reliability of a new approach, the point-to-point test (PTP), with the TPD. Twenty-one pain-free subjects attended the inter-examiner stage of the study. Eighteen of them were further recruited into an intra-examiner (reproducibility and repeatability) reliability study. PTP was performed on the three points plotted at the L3 spinal level. Point '0' overlapped with the L3 spinous process, from which points '1' and '2' were horizontally separated by 5 and 10 cm, respectively. Participants manually indicated a point previously touched by the examiner, while the distance (error) was measured. Reliability was determined with the intraclass correlation coefficient (ICC2,3). The results revealed good and moderate inter- and intra-examiner reliability at point '1' (ICC2,3 = 0.68-0.84) and good reliability at point '2' (ICC2,3 = 0.84-0.86). At point '0', reliability was moderate to poor (ICC2,3 = 0.13-0.63). TPD was characterised by a poor to moderate level of inter- (ICC2,1 = 0.51; ICC2,3 = 0.56) and intra-examiner reliability (ICC(2,1) = 0.50; ICC2,3 = 0.74). Our findings suggest that PTP is more reliable than TPD at two investigated points at the L3 spinal level. However, further research on PTP validity data is strongly warranted.

    Patients with peripheral arterial disease (PAD) at stage IIb, pain-free walking distance (PFWD) less than 100 m and unsuitable for revascularization have both impaired quality of life and severe clinical outcome. Aim of the study was to evaluate the efficacy of the prostacyclin analogue iloprost, added to standard therapy, in these patients. Patients were randomized to receive standard medical therapy (Group A) or standard therapy plus iloprost (Group B), for 1 year. Iloprost was administered for 10 days every 3 months. Treadmill test was performed every 3 months, in Group B before starting the 10-day iloprost cycle. Fifty patients in Group A and 51 in Group B were enrolled. Mean baseline and 12-month PFWD values were 75.4 ± 21.3 and 128.9 ± 62.9 for iloprost group and 70.3 ± 21.6 and 99.6 ± 62.6 m for controls. Patients treated with iloprost had significantly higher PFWD at 9 and 12 months. This finding was confirmed after carrying forward the last valid observation (124.7 ± 63.4 vs. 88.4 ± 63.1 m, P < 0.01). Major cardiovascular events occurred in 32.0% and 3.9% of patients in Group A and Group B, respectively (P < 0.001). Five patients in Group A died vs. none in Group B (P = 0.02). No serious unexpected adverse reactions occurred in patients receiving iloprost. Iloprost, added to standard therapy, significantly increases exercise capacity in patients with PAD at severe stage IIb. The percentage of patients who died or experienced major cardiovascular events was significantly lower in patients receiving iloprost. Future studies should focus on the effects of this therapy on clinical outcome. © 2013 Stichting European Society for Clinical Investigation Journal Foundation. Published by John Wiley & Sons Ltd.

    Neuroimaging studies have demonstrated the critical role of the insula in pain pathways and its close relation with the perceived intensity of nociceptive stimuli. We aimed to identify the structural and functional characteristics of the insula during periovulatory phase in women with primary dysmenorrhea (PDM), and further investigate its association with the intensity of perceived pain during menstruation. Optimized voxel-based morphometry and functional connectivity (FC) analyses were applied by using 3-dimensional T1-weighted and resting functional magnetic resonance imaging (fMRI) in 36 patients at the peri-ovulation phase and 29 age-, education-, and gender-matched healthy controls (HC). A visual analogue scale (VAS) was used to examine the intensity of the abdominal pain at periovulation and menstruation. In our results, PDM patients had significant higher VAS-rating during menstruaion than periovulation. Compared with the HC, PDM patients had lower gray matter density in the left anterior insula (aINS). Taken the left aINS as a seed region, we further found hypoconnectivity between aINS and medial prefrontal cortex (mPFC), which showed negative relation with the VAS during menstruation. As the aINS is a key site of the salience network (SN) and the mPFC is a critical region in the default mode network (DMN), it's implicated a trait-related central-alteration that communications between pain attention and perception networks were disrupted without the ongoing menstrual pain. Moreover, result of correlation analysis, at least in part, suggested a possible role of altered FC (pain-free period) in predicting pain perception (menstruation).

    Full Text Available Abstract Background This study aimed at investigating a potential effect caused by coccidia on the immune response to vaccine- and very virulent infectious bursal disase virus (vvIBDV in SPF chickens. Methods Two groups of three weeks old SPF chickens were vaccinated prior to inoculation with coccidia and challenge with virulent IBDV, all within a period of eight days. Two control groups were similarly treated, except that challenge with field virus was omitted in one group while inoculation with coccidia was omitted in the other group. Clinical signs, lesions in the intestines caused by coccidia, lesions in the bursa of Fabricius caused by IBDV, IBDV-antibody titres, and virus detection by reverse transcription polymerase chain reaction (RT-PCR were compared among the groups. Lymphoid tissues and swab samples were analysed by general RT-PCR, and positive results were identified by strain specific duplex (DPX RT-PCR. Results In the tripple-infected groups, vaccine strain IBDV was detected in spleen and thymus tissues, and no field virus was detected in bursa samples, contrary to the double-infected groups. Conclusion The results suggest an enhancing effect on the immune response caused by subclinical coccidiosis and vvIBDV acting in concert.

    To investigate whether rates of cartilage loss differ in knees with frequent baseline pain versus those without pain, after adjustment for radiographic osteoarthritis (OA) stage. One knee in each of 718 Osteoarthritis Initiative participants was examined: 310 with calculated Kellgren/Lawrence (K/L) grade 2, 299 with calculated K/L grade 3, and 109 with calculated K/L grade 4. Twelve-month change in (subregional) cartilage thickness was assessed by magnetic resonance imaging. Change in cartilage thickness in the central subregion of the weight-bearing medial femoral condyle and ordered value 1 (OV1) were selected as primary end points. Frequent knee symptoms were defined as pain, aching, or stiffness on most days of at least 1 month during the previous year. The mean 12-month rate of change in cartilage thickness in the central subregion of the medial femoral condyle was -12 μm (standardized response mean [SRM] -0.15) in knees without pain (n = 146), -27 μm (SRM -0.25) in those with infrequent pain (n = 255), and -54 μm (SRM -0.32) in those with frequent pain (n = 317). Rates differed significantly between frequently painful knees and pain-free knees after adjustment for age, sex, body mass index, and calculated K/L grade (P = 0.011, R(2) = 2.6%, partial R(2) for frequent pain = 1.4%). Similar results were found in stratified samples of calculated K/L grade 2/calculated K/L grade 3 knees, and in analyses restricted to knees with consistent pain frequency between baseline and followup. OV1 results showed similar trends but were not significant. Knees with frequent pain display greater rates of medial cartilage loss longitudinally than knees without pain, with or without adjustment or stratification for radiographic disease stage. Enrollment of participants with frequent knee pain in clinical trials can increase the observed rate of structural progression (i.e., cartilage loss) and sensitivity to change.

    Full Text Available Avian infectious bronchitis virus (IBV is prevalent in all countries with intensive poultry flocks. This disease is characterised primarily by respiratory signs, but some IBV strains may also infect other organs such as the intestinal and urogenital tracts. The aim of this study was to characterise the histopathological lesions and tissue tropism of Iranian isolate IR/773/2001(793/B of avian infectious bronchitis virus in different organs of experimentally infected SPF chickens. Forty-two one-day-old, specific pathogen-free (SPF chicks were divided randomly into two groups (21 chicks to each group. At the age of 12 days, one group was inoculated intra-ocularly with 103 EID50 of the 793/B isolate, and the other was kept as the control group. Tissue samples were collected at 2, 4, 6, 8, 10 and 12 days post-inoculation (PI. The IBV virus was detected in the caecal tonsils and cloaca from the 2nd to the 12th day PI. The virus was also detected in the kidneys from days 4–10 PI and in the bursa of Fabricius from days 4–12 PI. The virus was detected in the trachea, lungs and thymus. The most obvious histopathological lesions were found in the trachea, kidney, lungs and bursa of Fabricius. Amongst the lymphoid tissues, histopathological changes were found most frequently in the bursa of Fabricius. The results of this study indicated that the 793/B serotype of IBV is unlikely to cause mortality, severe clinical signs or gross lesions in infected chickens, but its replication in some tissues including the bursa of Fabricius could render birds susceptible to other micro-organisms.

    The objective of the present study was to investigate cortical differences between chronic low back pain (CLBP) subjects and pain-free controls with respect to habituation and processing of stimulus intensity. The use of a novel event-related fixed-interval areas (ERFIA) multilevel technique enables the analysis of event-related electroencephalogram (EEG) of the whole post stimulus range at a single trial level. This technique makes it possible to disentangle the cortical processes of habituation and stimulus intensity.In a cross-sectional study, 78 individuals with CLBP and 85 pain-free controls underwent a rating paradigm of 150 nonpainful and painful somatosensory electrical stimuli. For each trial, the entire epoch was partitioned into 20-ms ERFIAs, which acted as dependent variables in a multilevel analysis. The variability of each consecutive ERFIA period was modeled with a set of predictor variables, including 3 forms of habituation and stimulus intensity.Seventy-six pain-free controls and 65 CLBP subjects were eligible for analysis. CLBP subjects showed a significantly decreased linear habituation at 340 to 460 ms in the midline electrodes and C3 (Ps < .05) and had a significantly more pronounced dishabituation for the regions of 400 to 460 ms and 800 to 820 ms for all electrodes, except for T3 and T4 (Ps < .05). No significant group differences for stimulus intensity processing were observed.In this study, group differences with respect to linear habituation and dishabituation were demonstrated. By means of the ERFIA multilevel technique, habituation effects were found in a broad post stimulus range and were not solely limited to peaks. This study suggests that habituation may be a key mechanism involved in the transition process to chronic pain. Future studies with a longitudinal design are required to solve this issue.

  7. Evaluating the Photoprotective Effects of Ochre on Human Skin by In Vivo SPF Assessment: Implications for Human Evolution, Adaptation and Dispersal.

    Full Text Available Archaeological indicators of cognitively modern behaviour become increasingly prevalent during the African Middle Stone Age (MSA. Although the exploitation of ochre is viewed as a key feature of the emergence of modern human behaviour, the uses to which ochre and ochre-based mixtures were put remain ambiguous. Here we present the results of an experimental study exploring the efficacy of ochre as a topical photoprotective compound. This is achieved through the in vivo calculation of the sun protection factor (SPF values of ochre samples obtained from Ovahimba women (Kunene Region, Northern Namibia and the Palaeozoic Bokkeveld Group deposits of the Cape Supergroup (Western Cape Province, South Africa. We employ visible spectroscopy, energy-dispersive X-ray fluorescence (ED-XRF, X-ray diffraction (XRD and granulometric analyses to characterise ochre samples. The capacity of ochre to inhibit the susceptibility of humans to the harmful effects of exposure to ultraviolet radiation (UVR is confirmed and the mechanisms implicated in the efficacy of ochre as a sunscreen identified. It is posited that the habitual application of ochre may have represented a crucial innovation for MSA humans by limiting the adverse effects of ultraviolet exposure. This may have facilitated the colonisation of geographic regions largely unfavourable to the constitutive skin colour of newly arriving populations.

    Kinesiological taping (KT) is commonly used to improve symptoms associated with musculoskeletal disorders. However, review of the literature revealed minimal evidence to support the use of KT in treatment of shoulder disorders and controversy exists regarding the effect of KT in patients with shoulder impingement syndrome (SIS). The purpose of this study was to investigate the effect of KT on pain intensity during movement, pain experienced during the night (nocturnal pain), and pain-free shoulder range of motion (ROM) immediately after taping, after three days and after one week, in patients with SIS. Randomized, Double blinded, Placebo-controlled design. A total of 30 patients with SIS participated in this study. Patients were assigned randomly to a control (N = 15) and an experimental group (N = 15). The patients in the experimental group received a standardized therapeutic KT. The standardized, placebo neutral KT was applied for control group. KT was applied two times with a three day interval, remaining on during the 3 day interval. Both groups followed the same procedures. Pain-free active ROM during shoulder abduction, flexion, and elevation in the scapular plane was measured. Visual analogue scale (VAS) for pain intensity during movement or nocturnal pain and was assessed at baseline, immediately after KT, after three days, and one week after KT. The result of repeated measures ANOVA showed a significant change in pain level during movement, nocturnal pain, and pain-free ROM (p = 0.000) after KT in the experimental group. In the ANCOVA, controlling for pre-test scores, change in pain level at movement (p = 0.009) and nocturnal pain (p = 0.04) immediately after KT was significantly greater in the experimental group than in control group. There was no significant difference in ROM measures (p > 0.05) between groups immediately after KT. No significant differences were found between the two groups in the after one week measurements of pain intensity and

  12. Expression of 5-HT3 receptors and TTX resistant sodium channels (NaV1.8) on muscle nerve fibers in pain-free humans and patients with chronic myofascial temporomandibular disorders

    Science.gov (United States)

    2014-01-01

    Background Previous studies have shown that 5-HT3-antagonists reduce muscle pain, but there are no studies that have investigated the expression of 5-HT3-receptors in human muscles. Also, tetrodotoxin resistant voltage gated sodium-channels (NaV) are involved in peripheral sensitization and found in trigeminal ganglion neurons innervating the rat masseter muscle. This study aimed to investigate the frequency of nerve fibers that express 5-HT3A-receptors alone and in combination with NaV1.8 sodium-channels in human muscles and to compare it between healthy pain-free men and women, the pain-free masseter and tibialis anterior muscles, and patients with myofascial temporomandibular disorders (TMD) and pain-free controls. Methods Three microbiopsies were obtained from the most bulky part of the tibialis and masseter muscles of seven and six healthy men and seven and six age-matched healthy women, respectively, while traditional open biopsies were obtained from the most painful spot of the masseter of five female patients and from a similar region of the masseter muscle of five healthy, age-matched women. The biopsies were processed by routine immunohistochemical methods. The biopsy sections were incubated with monoclonal antibodies against the specific axonal marker PGP 9.5, and polyclonal antibodies against the 5-HT3A-receptors and NaV1.8 sodium-channels. Results A similar percentage of nerve fibers in the healthy masseter (85.2%) and tibialis (88.7%) muscles expressed 5-HT3A-receptors. The expression of NaV1.8 by 5-HT3A positive nerve fibers associated with connective tissue was significantly higher than nerve fibers associated with myocytes (P < .001). In the patients, significantly more fibers per section were found with an average of 3.8 ± 3 fibers per section in the masseter muscle compared to 2.7 ± 0.2 in the healthy controls (P = .024). Further, the frequency of nerve fibers that co-expressed NaV1.8 and 5-HT3A receptors was significantly

    Patellofemoral Pain (PFP) is highly prevalent among adults and adolescents. Localized mechanical hyperalgesia around the knee and tibialis anterior have been observed in people with PFP, but limited knowledge of potential manifestations of central sensitisation exists. The aims of this study were to study conditioned pain modulation (CPM) and wide-spread hyperalgesia in adults with PFP. This assessor-blinded cross-sectional study design compared CPM and mechanical pressure pain thresholds (PPT) between 33 adults (23 females) diagnosed with PFP and 32 age and sex matched pain-free controls. The investigator taking the PPT measurements was blinded to which participants had PFP. PPTs were reliably measured using a Somedic hand-held pressure algometer at three sites: 1) The centre of the patella, 2) the tibialis anterior muscle and 3) a remote site on the lateral epicondyle. For the assessment of CPM, experimental pain was induced to the contralateral hand by immersion into a cold water bath (conditioning stimulus), and assessment of PPTs (the test stimulus) was performed before and immediately after the conditioning stimulation. On average, the CPM paradigm induced a significant increase in PPTs across the three sites (6.3–13.5%, Ppain-free controls. PMID:29220355

    Zibotentan (ZD4054) is a specific endothelin A receptor antagonist in clinical development for the treatment of hormone-resistant prostate cancer (HRPC). In a Phase II trial in patients with pain-free or mildly symptomatic metastatic HRPC, zibotentan was well tolerated with a promising signal for prolonged overall survival compared with placebo. As part of this trial, the impact of zibotentan compared with placebo on health-related quality of life (HRQoL) was assessed. Patients were randomized to receive once-daily oral zibotentan 10 or 15 mg, or matching placebo. Patients were allocated to one of two questionnaires; the Functional Assessment of Cancer Therapy-Prostate (FACT-P) or the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), supplemented by PR25, specific for prostate cancer. Questionnaires were completed at baseline and every 4 weeks until disease progression when study treatment was discontinued. Compliance with questionnaire completion was >90% (286 of 312 patients) of the intention-to-treat population at baseline. Of baseline completers who were available for assessment (i.e., had not clinically progressed), 89% (164 of 184) and 83% (73 of 88) completed questionnaires at 12 and 24 weeks, respectively. HRQoL scores from both questionnaires were high at baseline and remained high throughout the study, with scores being similar in the zibotentan and placebo groups. However, some floor and ceiling effects were seen in the EORTC QLQ-C30 questionnaire. High-baseline HRQoL scores were maintained throughout treatment with zibotentan. The FACT-P instrument was selected to further assess the impact of zibotentan on HRQoL in the Phase III clinical trial program.

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

Each vaccinated group consisted of 10 chicken except 8 chicken for control group. SPF chicken were vaccinated with 1 dose of vaccine at 3 weeks olds, and then after 3 weeks post vaccination (at 6 weeks olds. All group of chicken were challenged with 106 EID50 per 0.1 ml via intranasal. The results showed, chicken vaccinated with H5N1 clade 2.1.3 product A and B gave 100 and 80% protection respectively, but showed challenged virus shedding, whereas vaccine of H5N1 clade 2.3.2 gave 100% protection from mortality and without virus shedding. Vaccines of AI H5N1 clade 2.1.3 product A was better than vaccine product B, and when chicken vaccinated against H5N1 clade 2.3.2, H5N1 clade 2.3.2 vaccine was the best to be used. In order to protect chicken from AI subtype H5N1 clade 2.1.3 and 2.3.2 in the field, a bivalent vaccine of H5N1 clade 2.1.3 and 2.3.2 subtypes should be developed.

Many of these have taken the form of ‘stewardship...... councils’ and ‘sustainability roundtables’ and have been designed around a set of institutional features seeking to establish legitimacy, fend off possible criticism, and ‘sell’ certifications to potential users. The concept of ‘roundtabling’ emphasizes the fitting a variety of commodity......-specific sustainability situations into a form that not only ‘hears more voices’ (as in ‘multi-stakeholder’), but also portrays to give them equal standing at the table of negotiations (roundtable), thus raising higher expectations on accountability, transparency and inclusiveness. In this article, I examine to what...

    2017-03-17

    The long-term substitution of fossil resources can only be achieved through a bio-based economy, with biorefineries and bio-based products playing a major role. However, it is important to assess the implications of the transition to a bio-based economy. Life cycle-based sustainability assessment is probably the most suitable approach to quantify impacts and to identify trade-offs at multiple levels. The extended utilisation of biomass can cause land use change and affect food security of the most vulnerable people throughout the world. Although this is mainly a political issue and governments should be responsible, the responsibility is shifted to companies producing biofuels and other bio-based products. Organic wastes and lignocellulosic biomass are considered to be the preferred feedstock for the production of bio-based products. However, it is unlikely that a bio-based economy can rely only on organic wastes and lignocellulosic biomass.It is crucial to identify potential problems related to socio-economic and environmental issues. Currently there are many approaches to the sustainability of bio-based products, both quantitative and qualitative. However, results of different calculation methods are not necessarily comparable and can cause confusion among decision-makers, stakeholders and the public.Hence, a harmonised, globally agreed approach would be the best solution to secure sustainable biomass/biofuels/bio-based chemicals production and trade, and to avoid indirect effects (e.g. indirect land use change). However, there is still a long way to go.Generally, the selection of suitable indicators that serve the purpose of sustainability assessment is very context-specific. Therefore, it is recommended to use a flexible and modular approach that can be adapted to various purposes. A conceptual model for the selection of sustainability indicators is provided that facilitates identifying suitable sustainability indicators based on relevance and significance in a

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

    Full Text Available In recent decades, the image of the international business environment has changed significantly. Studies conducted by UNCTAD shows that corporate phenomenon developments in the world economy is growing. Without claiming to present an exhaustive topic so vast we tried to capture some "facets" of sustainable development from the perspective of multinational corporations, given the expansion of these economic entities and strengthening their power in the global economy. We present more negative aspects of the actions of multinational corporations in terms of sustainable development, it is very important to know both sides of the coin, which will not only help transnational giants including release. Based on issues such as corporate social responsibility, environmental pollution and workers' rights, we sought to counter official statements. The conclusion is that these economic entities are real forces that can not be ignored in today's world and the obvious problem of sustainable development can not be addressed independently of the phenomenon, context we also identified some possible solutions to conflict of corporations and essence of the concept of sustainable development.

    Objective To investigate the extent of the cross-reactivity of hybrid capture 2 (HC2) assay and evaluate the potential effect of cross-reactivity on the long-term risk for cervical cancer and precancers. Methods Based on the Shanxi Province Cervical Cancer Screening Study-I (SPOCCS-I) cohort from 2005 to 2014 in Shanxi, China, SPF10-line probe assay (LiPA) was performed in all 598 HC2 positive and 300 random-selected HC2 negative cervical specimens. Ten-year cumulative incidence rate (CIR) of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) of these two tests was evaluated using Kaplan-Meier methods. Possible human papillomavirus (HPV) types to be cross-reacted by HC2 were also analyzed. Results The overall agreement between HC2 and SPF10-LiPA for detecting carcinogenic HPV was 73.27%. The highest 10-year cumulative risk of CIN2+ was observed in both HC2 positive and LiPA-carcinogenic HPV positive women (25.70%; 95% confidence interval [CI]=23.55%–27.91%), followed by HC2 positive but LiPA-non-carcinogenic HPV positive women (9.97%; 95% CI=8.57%–11.50%), HC2 negative but LiPA-carcinogenic HPV positive (2.56%; 95% CI=2.44%–2.70%) and HC2 positive but LiPA-HPV negative (1.85%; 95% CI=1.78%–1.92%) women. The proportion of cross-reactivity of HC2 with untargeted carcinogenic types was 8.9%, most of which were attributable to HPV26, 73, 82, 69, 71, 53, 11, 43, and 54. Conclusion The noticeable high risk of CIN2+ in women infected with cross-reacted non-carcinogenic HPV and low risk in those with miss-to-detective carcinogenic HPV supported an overall good clinical performance of HC2 for a general cervical cancer screening.

    Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

    Sustainability science (SS) is an 'emerging field of research dealing with the interactions between natural and social systems, and with how those interactions affect the challenge of sustainability: meeting the needs of present and future generations while substantially reducing poverty and conserving the planet's life support systems' (Kates, 2011; Clark, 2007). Bettencourt & Kaur (2011) identified more than 20,000 scientific papers published on SS topics since the 1980s with more than 35,000 distinct authors. They estimated that the field is currently growing exponentially, with the number of authors doubling approximately every 8 years. These scholars are undoubtedly using and generating a vast quantity and variety of data and information for both SS research and applications. Unfortunately we know little about what data the SS community is actually using, and whether or not the data that SS scholars generate are being preserved for future use. Moreover, since much SS research is conducted by cross-disciplinary, multi-institutional teams, often scattered around the world, there could well be increased risks of data loss, reduced data quality, inadequate documentation, and poor long-term access and usability. Capabilities and processes therefore need to be established today to support continual, reliable, and efficient preservation of and access to SS data in the future, especially so that they can be reused in conjunction with future data and for new studies not conceived in the original data collection activities. Today's long-term data stewardship challenges include establishing sustainable data governance to facilitate continuing management, selecting data to ensure that limited resources are focused on high priority SS data holdings, securing sufficient rights to allow unforeseen uses, and preparing data to enable use by future communities whose specific research and information needs are not yet known.

    Scientists are front and center in quantifying and solving environmental problems. Yet, as a spate of recent news articles in scientific journals point out, much can be done to enhance sustainability within the scientific enterprise itself, particularly by trimming the energy use associated with research facilities and the equipment therein (i,ii,iii, iv). Sponsors of research unwittingly spend on the order of $10 billion each year on energy in the U.S. alone, and the underlying inefficiencies drain funds from the research enterprise while causing 80 MT CO2-equivalent greenhouse-gas emissions (see Box). These are significant sums considering the opportunity costs in terms of the amount of additional research that could be funded and emissions that could be reduced if the underlying energy was used more efficiently. By following commercially proven best practices in facility design and operation, scientists--and the sponsors of science--can cost-effectively halve these costs, while doing their part to put society on alow-carbon diet.

    2016-12-15

    The remediation industry has grown exponentially in recent decades. International organizations of practitioners and remediation experts have developed several frameworks for integrating sustainability into remediation projects; however, there has been limited attention to how sustainability is approached and operationalized in sustainable remediation frameworks and practices - or whether sustainability plays any meaningful role at all in sustainable remediation. This paper examines how sustainability is represented in remediation frameworks and the guidance provided for practical application. Seven broad sustainability principles and review criteria are proposed and applied to a sample of six international remediation frameworks. Not all review criteria were equally satisfied and none of the frameworks fully met all criteria; however, the best performing frameworks were those identified as sustainability remediation frameworks. Intra-generational equity was addressed by all frameworks. Integrating social, economic and biophysical components beyond triple-bottom-line indicators was explicitly addressed only by the sustainable remediation frameworks. No frameworks provided principle- or rule-based guidance for dealing with trade-offs in sustainability decisions. Copyright © 2016 Elsevier Ltd. All rights reserved.

    / It is legitimate to ask whether and in what form tourism might contribute to sustainable development. This is not the same as sustainable tourism which, as a single-sector approach to development, may overlook important linkages with other sectors. If tourism is to contribute to sustainable development, then it must be economically viable, ecologically sensitive and culturally appropriate. Ecotourism is often advocated as being a sustainable form of tourism but imprecision in terminology clouds basic issues and there are strong economic, ecological, and cultural reasons for believing that, even in its purest forms, ecotourism is likely to present substantial challenges to destination areas, particularly if it competes for scarce resources and displaces existing uses and users. Sustainable tourism and ecotourism are not synonyms, many forms of ecotourism may not be sustainable, and if ecotourism is to contribute to sustainable development, then careful planning and management will be required.KEY WORDS: Ecotourism; Sustainable development; Development; Tourism

In this paper a typology of sustainability strategies is presented as well as a conceptual framework relating sustainability at the company level to the functional level...... of marketing. The central contribution of the typology is a strategic and managerial view on sustainability. Furthermore, the typology shows that sustainability in business is enacted from different areas of competences and fields in the literature (e.g. supply chain management, corporate branding, value...... creation, product innovation and business model innovation). The empirical basis for the typology is an exploratory study of managers' mindsets about sustainability as strategy.

  13. Health and sustainability.

    Science.gov (United States)

    Kjӕrgård, Bente; Land, Birgit; Bransholm Pedersen, Kirsten

    2014-09-01

    In the present article, we explore how sustainable development strategies and health promotion strategies can be bridged. The concept of the 'duality of structure' is taken as our starting point for understanding the linkages between health promotion and sustainable development, and for uncovering the structural properties or conditions which either enable or constrain sustainable public health initiatives. We argue that strategies towards health promotion are not sufficiently integrated with strategies for sustainable development, and thus political strategies aimed at solving health problems or sustainability problems may cause new, undesired and unforeseen environmental or health problems. First, we explore how the relation between health and sustainability is articulated in international policy documents. Next, we develop a model for understanding the relation between health promotion and sustainability. Third, we use examples from agriculture and food production to illustrate that health and sustainability are mutually enabling and constraining. We conclude that while the renewed focus on food security and food inequalities has brought the health and sustainability dimensions of the food system onto the political agenda, the conceptualization of duality between health and sustainability could be a new platform for a critical and theoretical stance towards the market-oriented food system strategy. Thinking along the lines of duality means that the integration of health promotion strategies and sustainable development strategies cannot be based on an approach to integration in which either health or sustainability is given precedence over the other. From a duality perspective, integration means conceiving sustainability from a health perspective and health from a sustainability perspective. © The Author (2013).

    Sustainability is the theme of our time and also the grandest challenge to humanity. Since the 1970s, the term, sustainable development, has frequently appeared in the scientific literature, governmental documents, media promotions for public goods, and commercial advertisements. However, the science that provides the theoretical foundation and practical guidance for sustainable development--sustainability science--only began to emerge in the beginning of the 21st century. Nevertheless, the field has rapidly developed in depth and expanded in scope during the past decade, with its core concepts and research methods coalescing. China, as the most populous country in the world and home to the philosophical root of sustainability science-the unity of man and nature, is obligated to take upon the challenge of our time, to facilitate global sustainability while pursuing the Chinese Dream, and to play a leading role in the development of sustainability science. Toward this grandiose goal, this paper presents the first Chinese introduction to sustainability science, which discusses its basic concepts, research questions, and future directions. Sustainability science is the study of the dynamic relationship between humans and the environment, particularly focusing on the vulnerability, robustness, resilience, and stability of the coupled human-environment system. It is a transdisciplinary science that integrates natural sciences with humanities and social sciences. It hinges on the environment-economy-society nexus, and merges basic and applied research. The key components of sustainability often change with time, place, and culture, and thus sustainability science needs to emphasize multi-scale studies in space and time, with emphasis on landscapes and regions over a horizon of 50 to 100 years. It needs to focus on the relationship between ecosystem services and human well-being, as influenced by biodiversity and ecosystem processes as well as climate change, land use

    ICT Innovations for Sustainability is an investigation of how information and communication technology can contribute to sustainable development. It presents clear definitions of sustainability, suggesting conceptual frameworks for the positive and negative effects of ICT on sustainable development. It reviews methods of assessing the direct and indirect impact of ICT systems on energy and materials demand, and examines the results of such assessments. In addition, it investigates ICT-based approaches to supporting sustainable patterns of production and consumption, analyzing them at various levels of abstraction – from end-user devices, Internet infrastructure, user behavior, and social practices to macro-economic indicators.   Combining approaches from Computer Science, Information Systems, Human-Computer Interaction, Economics, and Environmental Sciences, the book presents a new, holistic perspective on ICT for Sustainability (ICT4S). It is an indispensable resource for anyone working in the area of ICT...

  2. Sustainability and substitutability.

    Science.gov (United States)

    Fenichel, Eli P; Zhao, Jinhua

    2015-02-01

    Developing a quantitative science of sustainability requires bridging mathematical concepts from fields contributing to sustainability science. The concept of substitutability is central to sustainability but is defined differently by different fields. Specifically, economics tends to define substitutability as a marginal concept while fields such as ecology tend to focus on limiting behaviors. We explain how to reconcile these different views. We develop a model where investments can be made in knowledge to increase the elasticity of substitution. We explore the set of sustainable and optimal trajectories for natural capital extraction and built and knowledge capital accumulation. Investments in substitutability through knowledge stock accumulation affect the value of natural capital. Results suggest that investing in the knowledge stock, which can enhance substitutability, is critical to desirable sustainable outcomes. This result is robust even when natural capital is not managed optimally. This leads us to conclude that investments in the knowledge stock are of first order importance for sustainability.

    2015-12-01

    Full Text Available The growing concern over global warming and significant ecological changes requires sustainable development in all fields of science and technology. Concrete not only consumes huge amount of energy and natural sources, but also emits large amount of CO2, mainly due to the production of cement. It is evident that such large amount of concrete production has put significant impact on the energy, resource, environment, and ecology of the society. Hence, how to develop the concrete technology in a sustainable way has become a significant issue. In this paper, some of Korean researches for sustainable development of concrete are presented. These are sustainable strengthening for deteriorated concrete structure, sustainable reinforcement of new concrete structure, sustainable concrete using recycled aggregate and supplementary cementing materials and finally application of each technique to precast concrete.

  8. Sustainability assessment and complementarity

    Directory of Open Access Journals (Sweden)

    Hugo F. Alrøe

    2016-03-01

    Full Text Available Sustainability assessments bring together different perspectives that pertain to sustainability to produce overall assessments, and a wealth of approaches and tools have been developed in the past decades. However, two major problems remain. The problem of integration concerns the surplus of possibilities for integration; different tools produce different assessments. The problem of implementation concerns the barrier between assessment and transformation; assessments do not lead to the expected changes in practice. We aim to analyze issues of complementarity in sustainability assessment and transformation as a key to better handling the problems of integration and implementation. Based on a generalization of Niels Bohr's complementarity from quantum mechanics, we have identified two forms of complementarity in sustainability assessment, observer stance complementarity and value complementarity. Unlike many other problems of sustainability assessment, complementarity is of a fundamental character connected to the very conditions for observation. Therefore, complementarity cannot be overcome methodologically, only handled better or worse. Science is essential to the societal goal of sustainability, but these issues of complementarity impede the constructive role of science in the transition to more sustainable structures and practices in food systems. The agencies of sustainability assessment and transformation need to be acutely aware of the importance of different perspectives and values and the complementarities that may be connected to these differences. An improved understanding of complementarity can help to better recognize and handle issues of complementarity. These deliberations have relevance not only for sustainability assessment, but more generally for transdisciplinary research on wicked problems.

    Jensen, Karsten Klint

    2007-01-01

    The widely used concept of sustainability is seldom precisely defined, and its clarification involves making up one's mind about a range of difficult questions. One line of research (bottom-up) takes sustaining a system over time as its starting point and then infers prescriptions from...... this requirement. Another line (top-down) takes an economical interpretation of the Brundtland Commission's suggestion that the present generation's needsatisfaction should not compromise the need-satisfaction of future generations as its starting point. It then measures sustainability at the level of society...... a clarified ethical goal, disagreements can arise. At present we do not know what substitutions will be possible in the future. This uncertainty clearly affects the prescriptions that follow from the measure of sustainability. Consequently, decisions about how to make future agriculture sustainable...

    2013-01-01

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

    Sustainable design is a collective process whereby the built environment achieves unprecedented levels of ecological balance through new and retrofit construction, with the goal of long-term viability and humanization of architecture. Focusing on the environmental context, sustainable design merges the natural, minimum resource conditioning solutions of the past (daylight, solar heat, and natural ventilation) with the innovative technologies of the present.  The desired result is an integrated “intelligent” system that supports individual control with expert negotiation for resource consciousness. International experts in the field address the fundamental questions of sustainable design and landscape management: How should the sustainability of landscapes and buildings be evaluated? Which targets have to be set and which thresholds should not be exceeded? What forms of planning and governance structures exist and to what extent do they further the goals of sustainability?  Gathering 30 peer-reviewed ent...

    Full Text Available Angela Mariani,1 Antonella Vastola2 1Department of Economic and Legal Studies, University Parthenope, Naples, 2School of Agricultural, Forestry, Food and Environmental Sciences, University of Basilicata, Potenza, Italy Abstract: The winegrowing sector worldwide is strongly committed to improving environmental and social sustainability. The aim of this work, based on a literature review, is to highlight current sustainability perspectives and the related main issues. There is a broad consensus that the challenge to achieve a greater spread of sustainable practices is to enhance environmental and social sustainability while maintaining economic viability. From the producers' point of view, the priority is to bridge the still substantial knowledge gaps in terms of perceived environmental benefits, economic benefits, and costs. Thus, an increased research effort focusing on the costs and benefits of different winegrowing practices and technical assistance with implementation might support their diffusion. Moreover, targeted marketing strategies are needed to: enhance consumers' involvement and their attitude toward sustainable wine; improve understanding and use of sustainable labels and claims; and raise awareness of some environmental credentials of wine packaging, mainly with reference to lightweight glass bottles. Keywords: winegrower, sustainability, wine, consumer, marketing strategies

    The Independent Schools Foundation Academy (ISF) in Hong Kong established a sustainability policy in 2015, which explicitly states, "an experimentally integrated, environmentally and ethically sustainable system of science education and conservation practices based on the 2012 Jeju Declaration of the World Conservation Congress will be implemented through the school". ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

    Full Text Available Sustainable use of the planet is based on the assumption that humankind can maintain conditions suitable for inhabiting the planet indefinitely. No robust evidence supports this assumption nor rejects it, and adequate evidence on this issue may not be available for centuries. Numeracy is the ability to use or understand numerical techniques of mathematics. Even if adequate numerical data were available, the important decisions humankind makes regarding sustainable use of the planet should not be guided by numerical information alone, such as economic numbers, but by eco- and sustainability ethics, which provides a values framework that indicates how the numbers should be used and interpreted.

    Directory of Open Access Journals (Sweden)

    John Cairns Jr.

    2003-09-01

    Full Text Available Humans must acknowledge that the biosphere is the essential support for all living organisms. In order to achieve sustainable use of the planet, humans must proceed beyond egocentrism, ethnocentrism, homocentrism, and biocentrism to ecocentrism. National states, with present policies, are a major obstacle to sustainable use of the planet. However, there is some evidence that the individual has increasing sovereignty at the expense of both nation states and the environment. Still, the primary obstacle to sustainability is inherent in the present system of sovereign nation states. The basic question is how much sovereignty must nation-states and individuals relinquish to preserve the health of Earth's biospheric life support system. A free and open exchange of thoughts on this subject is long overdue. To acheive sustainable use of the planet, humankind must view its identity within the context of the interdependent web of life.

    2012-01-01

    The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, and 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

    Full Text Available In the quest for achieving sustainable cities, Intelligent and Knowledge City Programmes (ICPs and KCPs represent cost-efficient strategies for improving the overall performance of urban systems. However, even though nobody argues on the desirability of making cities “smarter”, the fundamental questions of how and to what extent can ICPs and KCPs contribute to the achievement of urban sustainability lack a precise answer. In the attempt of providing a structured answer to these interrogatives, this paper presents a methodology developed for investigating the modalities through which ICPs and KCPs contribute to the achievement or urban sustainability. Results suggest that ICPs and KCPs efficacy lies in supporting cities achieve a sustainable urban metabolism through optimization, innovation and behavior changes.

    THIS IS THE THIRD YEAR BPA has reported on sustainability program accomplishments. The report provides an opportunity to review progress made on sustainability initiatives, evaluate how far we have come and how much we can improve. The program has demonstrated maturation as the concepts of sustainability and resource conservation are communicated and understood. The sustainability program started as an employee-driven “grass roots” effort in 2010. Sustainability is becoming a consideration in how work is performed. The establishment of several policies supporting sustainability efforts proves the positive progress being made. In 2009, BPA became a founder and member of The Climate Registry, a nonprofit collaboration that sets standards to calculate, verify and report greenhouse gas emissions. This year, BPA completed and published our Greenhouse Gas inventory for the years of 2009, 2010 and 2011. The 2012 inventory is currently in the process of third-party verification and scheduled for public release in January 2014. These inventories provide a concrete measure of the progress we are making.

    The mission of the Sustainable Bioenergy Development Center (SBDC) is to enhance the capability of America’s bioenergy industry to produce transportation fuels and chemical feedstocks on a large scale, with significant energy yields, at competitive cost, through sustainable production techniques. Research within the SBDC is organized in five areas: (1) Development of Sustainable Crops and Agricultural Strategies, (2) Improvement of Biomass Processing Technologies, (3) Biofuel Characterization and Engine Adaptation, (4) Production of Byproducts for Sustainable Biorefining, and (5) Sustainability Assessment, including evaluation of the ecosystem/climate change implication of center research and evaluation of the policy implications of widespread production and utilization of bioenergy. The overall goal of this project is to develop new sustainable bioenergy-related technologies. To achieve that goal, three specific activities were supported with DOE funds: bioenergy-related research initiation projects, bioenergy research and education via support of undergraduate and graduate students, and Research Support Activities (equipment purchases, travel to attend bioenergy conferences, and seminars). Numerous research findings in diverse fields related to bioenergy were produced from these activities and are summarized in this report.

The broad journal title Social Sciences presents the opportunity for all social science scholars to have integrated consideration regarding the sustainability of humanity, because I am sure that science and technology alone cannot help. Science and technology may have in fact been contributing to accelerate the depletion of nonrenewable natural resources and putting human sustainability at risk since the industrial revolution about 150 years ago. I hope all intellectuals studying anthropology, archaeology, administration, communication, criminology, economics, education, government, linguistics, international relations, politics, sociology and, in some contexts, geography, history, law, and psychology publish with us to seek a solution to sustain humanity. Sustainability itself will also be a main topic of the journal Social Sciences. In addition to this integrated forum for social sciences, more topic specific journals, such as the already publishing Societies [2], will be launched. [...

    Full Text Available Sustainable water systems often comprise complex combinations of traditional and new system components that mimic natural processes. These green systems aim to protect public health and safety, and restore natural and human landscapes. Green infrastructure elements such as most sustainable drainage systems trap storm water but may contaminate groundwater. There is a need to summarize recent trends in sustainable water systems management in a focused document. The aim of this special issue is therefore to disseminate and share scientific findings on novel sustainable water systems addressing recent problems and opportunities. This special issue focuses on the following key topics: climate change adaptation and vulnerability assessment of water resources systems; holistic water management; carbon credits; potable water savings; sustainable water technologies; nutrient management; holistic storm water reuse; water and wastewater infrastructure planning; ecological status of watercourses defined by the Water Framework Directive. The combined knowledge output advances the understanding of sustainable water, wastewater and storm water systems in the developed and developing world. The research highlights the need for integrated decision-support frameworks addressing the impact of climate change on local and national water resources management strategies involving all relevant stakeholders at all levels.

  14. Biofuels and sustainability.

    Science.gov (United States)

    Solomon, Barry D

    2010-01-01

    Interest in liquid biofuels production and use has increased worldwide as part of government policies to address the growing scarcity and riskiness of petroleum use, and, at least in theory, to help mitigate adverse global climate change. The existing biofuels markets are dominated by U.S. ethanol production based on cornstarch, Brazilian ethanol production based on sugarcane, and European biodiesel production based on rapeseed oil. Other promising efforts have included programs to shift toward the production and use of biofuels based on residues and waste materials from the agricultural and forestry sectors, and perennial grasses, such as switchgrass and miscanthus--so-called cellulosic ethanol. This article reviews these efforts and the recent literature in the context of ecological economics and sustainability science. Several common dimensions for sustainable biofuels are discussed: scale (resource assessment, land availability, and land use practices); efficiency (economic and energy); equity (geographic distribution of resources and the "food versus fuel" debate); socio-economic issues; and environmental effects and emissions. Recent proposals have been made for the development of sustainable biofuels criteria, culminating in standards released in Sweden in 2008 and a draft report from the international Roundtable on Sustainable Biofuels. These criteria hold promise for accelerating a shift away from unsustainable biofuels based on grain, such as corn, and toward possible sustainable feedstock and production practices that may be able to meet a variety of social, economic, and environmental sustainability criteria.

    Brown, Becky J.; Hanson, Mark E.; Liverman, Diana M.; Merideth, Robert W.

    1987-11-01

    Sustainability is increasingly viewed as a desired goal of development and environmental management. This term has been used in numerous disciplines and in a variety of contexts, ranging from the concept of maximum sustainable yield in forestry and fisheries management to the vision of a sustainable society with a steady-state economy. The meaning of the term is strongly dependent on the context in which it is applied and on whether its use is based on a social, economic, or ecological perspective, Sustainability may be defined broadly or narrowly, but a useful definition must specify explicitly the context as well as the temporal and spatial scales being considered. Although societies differ in their conceptualizations of sustainability, indefinite human survival on a global scale requires certain basic support systems, which can be maintained only with a healthy environment and a stable human population. A clearer understanding of global sustainability and the development of appropriate indicators of the status of basic support systems would provide a useful framework for policy making.

  16. Human Capital and Sustainability

    Directory of Open Access Journals (Sweden)

    Garry Jacobs

    2011-01-01

    Full Text Available A study of sustainability needs to consider the role of all forms of capital—natural, biological, social, technological, financial, cultural—and the complex ways in which they interact. All forms of capital derive their value, utility and application from human mental awareness, creativity and social innovation. This makes human capital, including social capital, the central determinant of resource productivity and sustainability. Humanity has entered the Anthropocene Epoch in which human changes have become the predominant factor in evolution. Humanity is itself evolving from animal physicality to social vitality to mental individuality. This transition has profound bearing on human productive capabilities, adaptability, creativity and values, the organization of economy, public policy, social awareness and life styles that determine sustainability. This article examines the linkages between population, economic development, employment, education, health, social equity, cultural values, energy intensity and sustainability in the context of evolving human consciousness. It concludes that development of human capital is the critical determinant of long-term sustainability and that efforts to accelerate the evolution of human consciousness and emergence of mentally self-conscious individuals will be the most effective approach for ensuring a sustainable future. Education is the primary lever. Human choice matters.

  17. Sustainable IT and IT for Sustainability

    Science.gov (United States)

    Liu, Zhenhua

    Energy and sustainability have become one of the most critical issues of our generation. While the abundant potential of renewable energy such as solar and wind provides a real opportunity for sustainability, their intermittency and uncertainty present a daunting operating challenge. This thesis aims to develop analytical models, deployable algorithms, and real systems to enable efficient integration of renewable energy into complex distributed systems with limited information. The first thrust of the thesis is to make IT systems more sustainable by facilitating the integration of renewable energy into these systems. IT represents the fastest growing sectors in energy usage and greenhouse gas pollution. Over the last decade there are dramatic improvements in the energy efficiency of IT systems, but the efficiency improvements do not necessarily lead to reduction in energy consumption because more servers are demanded. Further, little effort has been put in making IT more sustainable, and most of the improvements are from improved "engineering" rather than improved "algorithms". In contrast, my work focuses on developing algorithms with rigorous theoretical analysis that improve the sustainability of IT. In particular, this thesis seeks to exploit the flexibilities of cloud workloads both (i) in time by scheduling delay-tolerant workloads and (ii) in space by routing requests to geographically diverse data centers. These opportunities allow data centers to adaptively respond to renewable availability, varying cooling efficiency, and fluctuating energy prices, while still meeting performance requirements. The design of the enabling algorithms is however very challenging because of limited information, non-smooth objective functions and the need for distributed control. Novel distributed algorithms are developed with theoretically provable guarantees to enable the "follow the renewables" routing. Moving from theory to practice, I helped HP design and implement

    Wijethilake, Chaminda

    2017-07-01

    This study examines to what extent corporations use sustainability control systems (SCS) to translate proactive sustainability strategy into corporate sustainability performance. The study investigates the mediating effect of SCS on the relationship between proactive sustainability strategy and corporate sustainability performance. Survey data were collected from top managers in 175 multinational and local corporations operating in Sri Lanka and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). SCS were observed to only partially mediate the relationship between proactive sustainability strategy and corporate sustainability performance. The mediating effect of SCS is further examined under three sustainability strategies; environmental and social strategies reveal a partial mediation, while the economic strategy exhibits no mediation. The study also finds that (i) a proactive sustainability strategy is positively associated with SCS and corporate sustainability performance and (ii) SCS are positively associated with corporate sustainability performance.

  20. Towards sustainable development

    Science.gov (United States)

    Munn, R. E.

    Sustainable development is a difficult phrase to define, particularly in the context of human ecosystems. Questions have to be asked, such as "Sustainable for whom?" "Sustainable for what purposes?" "Sustainable at the subsistence or at the luxury level?" and "Sustainable under what conditions?" In this paper, development is taken to mean improving the quality of life. (If development were to mean growth, then it could not be sustained over the long term.) Studies of development must, of course, consider economic factors, particularly in the case of societies who suffer from the pollution of poverty. However, cultural and environmental factors are equally important. In fact, development is not sustainable over the long term if it is not ecologically sustainable. The terms maximum sustainable yield of a renewable resource, carrying capacity of a region and assimilative capacity of a watershed or airshed are discussed. Approaches using these resource management tools are recommended when external conditions are not changing very much. The problem today is that unprecedented rates of change are expected in the next century, not only of environmental conditions such as climate but also of socioeconomic conditions such as renewable resource consumption and populations (of both people and of automobiles)! In rapidly changing situations, policies must be adopted that strengthen resilence and ecosystem integrity; that is, society must increase its ability to adapt. Maintaining the status quo is a long-term prescription for disaster. The problem is of course that little is known about how to design strategies that will increase resilience and ecosystem integrity, and this area of research needs to be strengthened. Some suggestions on appropriate indicators of ecosystem integrity are given in the paper but these need considerable refinement. One of the main problems with long-term environmental policy formulation is the uncertainty to be expected, including the possibility

  1. Sustainable Consumption Dilemmas

    Directory of Open Access Journals (Sweden)

    Kees Vringer

    2017-06-01

    Full Text Available To examine which considerations play a role when individuals make decisions to purchase sustainable product varieties or not, we have conducted a large scale field experiment with more than 600 participating households. Households can vote on whether the budgets they receive should only be spent on purchasing the sustainable product variety, or whether every household in a group is free to spend their budget on any product variety. By conducting several treatments, we tested whether people tend to view sustainable consumption as a social dilemma or as a moral dilemma. We find little support for the hypothesis that social dilemma considerations are the key drivers of sustainable consumption behaviour. Participants seem to be caught in a moral dilemma in which they not only weigh their individual financial costs with the sustainable benefits but they also consider the consequences of restricting other people’s freedom of choice. Complementary survey results further substantiate this claim and show that many people are reluctant to impose restrictions on their peers, but, at the same time, our results also suggest substantial support for the government to regulate the availability of unsustainable product varieties.

  2. Sustainability and sacred values

    Directory of Open Access Journals (Sweden)

    John Cairns Jr.

    2002-09-01

    Full Text Available Successful implementation of the quest for sustainable use of the planet requires that human society both reexamine and expand present views of what is sacred and what is not. The most important aspect will be going beyond a homocentric focus to a biocentric emphasis. A unifying theme would be the desire to leave a habitable planet for human descendants and those of other species. It is unlikely that society can be confident of achieving sustainability until persuasive evidence supporting this belief has existed for several generations. In order for sustainable use of the planet to persist indefinitely, the conditions essential to this state must be morally preserved on sacred grounds. Viewing natural systems as sacred requires not only preventing damage to them but, wherever possible, repairing damage to them caused by humankind.

  8. Sustainability in a nutshell.

    Science.gov (United States)

    Silvertown, Jonathan

    2004-06-01

    Sustainable exploitation is widely advocated as a strategy for reconciling economic pressures upon natural habitats with nature conservation. Two recent papers examine different aspects of the sustainability of the nut harvest on wild populations of Brazil nut trees Bertholletia excelsa in Amazonia. Peres et al. find that many populations of the Brazil nut tree lack juvenile trees and are not regenerating. In a socioeconomic study, Escobal and Aldana find that nut-gathering provides insufficient income on its own to support nut-gatherers and that their other income-raising activities damage the forest. The existence of a market for rainforest products is, therefore, not sufficient on its own to prevent habitat destruction or the overexploitation of the resource and a more sophisticated approach to sustainability is required. Development of a market in ethically traded Brazil nuts might be one solution.

    Full Text Available Tourism and sustainable development are the subject of many initiatives and public or private debates in Romania. The main problem to which these initiatives try to find an answer is mostly related to the income generation for the local communities by using rationally and efficiently the local potential, in agreement with the economic, social, natural, and cultural factors. Consequently, some measures should be taken, and the tourist sector as a whole needs all the methods of sustainable development: new technologies, change of social behaviour, change of environmental legislation, methods of environmental management, better planning and development of control procedures. In this article, we presented a model of tourism development which should be applied in all the regions of great tourist attraction, and we realised a synthesis of the socio-economic advantages of sustainable tourism.

  10. Is Globalisation Sustainable?

    Directory of Open Access Journals (Sweden)

    Mohsin Raza

    2010-01-01

    Full Text Available It is clear that globalisation is something more than a purely economic phenomenon manifesting itself on a global scale. Among the visible manifestations of globalisation are the greater international movement of goods and services, financial capital, information and people. In addition, there are technological developments, more international cultural exchanges, facilitated by the freer trade of more differentiated products as well as by tourism and immigration, changes in the political landscape and ecological consequences. In this paper, we link the Maastricht Globalisation Index with Sustainability Indices to analyse if more globalised countries are doing better in terms of sustainable development and its dimensions. The results seem to suggest that the process of globalisation may render world development more sustainable.

They use their authority...... and edification skills to promote Green IS to the organizational agenda. If the issue is aligned with the organizational agenda, it receives management’s endorsement. The empirical case also shows two types of systemic feedback that can fuel a self-reinforcing sustainability process. The first type of feedback...

    Full Text Available Even if sustainable development is a concept that gained quite recently its scientific prestige, through contribution of researchers its content has upgraded to a high degree of conceptual luggage and, through contribution from governance representatives, has gained an impressive good-practice background. Allowing the use of different methodological premises and conceptual tools, sustainable development paradigm is equipped with all the elements that would allow the opening of new horizons of knowledge. Based on the facility which can operate the concept of sustainable development, the European Union aims to develop both a more competitive economy based on environmental protection as well as a new governance of economic policy. This on one hand demonstrates the sustainable development ability to irradiate creativity towards the establishment of interdisciplinary bridges and on the other hand explains the growing interest of researchers interested in the problem of analyzing in detail this fruitful concept. Launched first as a theoretical framework to serve justify actions responsible for weighting economic growth, the concept of Sustainable Development has quickly become a topic of ethical debate circumscribed to the area of perfectibility of human nature to the necessity registry. In this regard, the philosophical content of this paradigm could not remain outside researchers concerns, who want to provide both policy makers and the general public a wide range of evidence to demonstrate the viability of this paradigm. Academia waits until maximization of the contribution of governance to achieve sustainable economic development, which consists in conjunction of this upward path with the momentum given by public policy sync, perfectly adapted for globalization era and all crises to come. However, because this concept based its structure and composition on three pillars, equally important economy, society and environment any attempt to strengthen

    Global dietary patterns changed dramatically in the past 50 years, presenting both a boom and a threat to the health and well-being of populations everywhere. We need sustainable diets, with low-input, local and seasonal agro-ecological food productions as well as short distance production-consumption nets for fair trade. The development of a global food system able to guarantee everyone a balanced food intake requires health professionals an awareness and a commitment to increasingly complex education. Dietary changes such as the adherence of to the Mediterranean Dietary Pattern can reduce the environmental footprint and thus the use of natural resources. Increased focus on improving the utilization of freshwater fishes and the correct use of the waters of rivers and lakes should also be encouraged. Cultural heritage, food quality and culinary skills are other key aspects determining sustainable dietary patterns and food security. The Mediterranean street food (Mediterraneità), for intrinsic characteristics, can represent valid model to address the main issues concerning the sustainable food system. The issues of sustainability offer a great opportunity to nutritional science and scientists to play a more central role in the political analysis of future food systems. We are confident that preserve the past helps us understand the present and build for the future, the Mediterranean lifestyle is much more than the Mediterranean diet and, finally, the rivers and the lakes may be our future.

  1. Building Sustainability Assessment

    Full Text Available Although social, economic, and cultural indicators are of substantial importance to the concept of sustainable building, this concept is usually related to environmental characteristics. Any building level assessment method is complex and involves contradictory aspects. Moreover, emphasizing qualitative criteria only increases confusion. R&D and standardization are thus concentrated to transparency and usability of the environmental methods. Other directions of research aim at performance-based design and methods to take regional and cultural aspects into account. In this paper, the perspectives of the sustainability assessment of a whole building are presented, based on a state of the art, feasibility study on performance analysis and the development of an extended life-cycle assessment for buildings. Using various tools, and based on the case studies of building sustainability assessment, environmental indicators were often shown to be of lesser importance than the other, soft ones. The first steps in the development of a building sustainability assessment method for Portuguese residential buildings will be presented and discussed in the end.

  7. Partitioning ecosystems for sustainability.

    Science.gov (United States)

    Murray, Martyn G

    2016-03-01

    Decline in the abundance of renewable natural resources (RNRs) coupled with increasing demands of an expanding human population will greatly intensify competition for Earth's natural resources during this century, yet curiously, analytical approaches to the management of productive ecosystems (ecological theory of wildlife harvesting, tragedy of the commons, green economics, and bioeconomics) give only peripheral attention to the driving influence of competition on resource exploitation. Here, I apply resource competition theory (RCT) to the exploitation of RNRs and derive four general policies in support of their sustainable and equitable use: (1) regulate resource extraction technology to avoid damage to the resource base; (2) increase efficiency of resource use and reduce waste at every step in the resource supply chain and distribution network; (3) partition ecosystems with the harvesting niche as the basic organizing principle for sustainable management of natural resources by multiple users; and (4) increase negative feedback between consumer and resource to bring about long-term sustainable use. A simple policy framework demonstrates how RCT integrates with other elements of sustainability science to better manage productive ecosystems. Several problem areas of RNR management are discussed in the light of RCT, including tragedy of the commons, overharvesting, resource collapse, bycatch, single species quotas, and simplification of ecosystems.

  8. The macroecology of sustainability.

    Directory of Open Access Journals (Sweden)

    Joseph R Burger

    Full Text Available The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1 physical conservation laws govern the flows of energy and materials between human systems and the environment, 2 smaller systems are connected by these flows to larger systems in which they are embedded, and 3 global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

The contribution of the business to a promising future should come from a fully integrated sustainability in its DNA and strategies.This paper focuses on the needed sustainable strategies for scaling up the contribution of the companies to sustainable development in the future. At the beginning, we analyze the main theoretical points of view on sustainability. Then, we explain how companies could achieve the sustainability by following the steps of a difficult process and the present performances in sustainability of large companies around the world. Finally, we suggest four strategies that businesses could design and implement in order to scaling up their sustainability in the future.The research has two important conclusions on sustainability in business. One is that the sustainability pays off if it is integrated in the DNA of the companies. The other conclusion says that the companies will succeed to make the needed transformation for achieving a better sustainability in the future only if they design and perform strategies focused on improving sustainability.

  13. Marketing Sustainable Retail Development

    Directory of Open Access Journals (Sweden)

    Dragan Ilić

    2013-06-01

    Full Text Available One of the primary benefits of sustainable retail over the long run has to be the marketing gain from having something other competitors do not: lower operating costs, a more socially responsible public profile, ease of gaining planning approval for new projects, better access to certain investment pools, higher rents (in the case of developers, ease of recruiting and retaining key people. Each of these benefits needs marketing and public relations support; each benefits from a clear and consistent corporate message that promotes sustainable retail. To date, there are very few retailers or developers who have championed sustainability long enough, consistently enough and with enough actual demonstration of changes in standard operations to gain the benefits of green marketing, but the very paucity of examples serves to underscore the point: the green marketing space is wide open for large retailers and developers. What would be the marketing steps that a company could take to benefit from its “sustainability focus?” The key to any marketing program is to differentiate a company’s actions from those of competitors and to do it along lines that its various stakeholders care about. This practice of differentiation is often expressed as “finding a difference that makes a difference, to someone who makes difference to you.” For retail developers, the first differentiator should be to attract more and better tenants to all of their centers, tenants who value lower operating costs and the developer’s program of sustainable development and corporate social responsibility.

    2012-12-01

    Full Text Available This paper describes one of the major challenges of the future: the sustainable development of the society. Sustainability is now increasingly recognized as central to the growth of emerging market economies. For the banking sector, this represents both a demand for greater social and environmental responsibility as well as a new landscape of business opportunity. Several years ago, the main part of the banks did not consider the social and environmental problems relevant for their operations. Recently, the banks began to realize the major impact of the sustainable development over the way of ulterior development of the society and, implicitly over the way of creating of the banking value in the future. In this context, the development of a banking management system, based on sustainable principles represents one of the provocations of these days.Starting from literature in the sustainable banking management field in this paper are presented several relevant issues related to risk management in the context of sustainable banking financing: the need to implement the sustainable management principles in financial and banking industry; the role of banks in sustainable development of society; social and environmental risk management policies, events that have shaped the role of the banking sector in sustainable development; international standards regarding sustainable banking management such us: Equator Principles for sustainable investment projects’ financing or GRI principles for sustainable reporting. Furthermore, we developed a practical case study related to the implementation of sustainable banking management at Bank of America.

  1. Sustainable regulation of construction.

    Science.gov (United States)

    2000-11-01

    The seminar examined the role building codes and regulations can have in promoting a more sustainable approach to construction, particularly through their application to non-industrial building materials. A range of building materials such as straw, bamboo, rammed earth, adobe, and cob (a mixture of clay and chopped straw) were described and illustrated by slides to show their building potential. The current codes have a prime concern to protect the health and safety of people from the built environment. They have been developed almost exclusively for mainstream industrial materials and methods of construction, which makes them difficult to use with alternative, indigenous, or non-industrial building materials, even though those materials may be considered more sustainable. The argument was put forward that with only one-third of the world population living in modern industrial buildings today, it is not sustainable to re-house the remaining rapidly expanding population in high technology dwellings. Many of the low technology building materials and methods now used by the majority of people in the world need only incremental improvement to be equal or superior to many of their industrial replacements. Since these can be more sustainable methods of building, there needs to be an acceptance of the use of alternative materials, particularly in the developing parts of the world, where they are being rejected for less sustainable industrial methods. However, many codes make it difficult to use non-industrial materials; indeed, many of the industrial materials would not meet the demands that must be now met if they were now being introduced as new materials. Consequently, there is a need to develop codes to facilitate the use of a wider range of materials than in current use, and research is needed to assist this development. Sustainable regulation should take into account the full range of real impacts that materials and systems have in areas such as resource use and

    Full Text Available In recent years, there is a growing focus on corporate operations especially since the publication of the first environmental reports in 1989. Companies have started to publish information about its environmental, social and sustainability policies. The study examines the sustainability reporting elements of Borsa Istanbul Sustainability Index (BIST in Turkey and to evaluate which elements is most vital in this context. This study will begin with the sustainability reporting that will be examined under the roof of corporation sustainability and end with the examination of sustainability reports of 15 firms, which are included in the BIST Sustainability Index in Turkey, and a content analysis. The reports of companies under study were taken from special web site and GRI (Global Reporting Initiative database of companies. Being the first study in examining the sustainability report of companies in BIST Sustainability Index, it is expected to contribute in literature about sustainability reporting recently started to gain importance in Turkey.

  8. Interpreting Sustainability for Urban Forests

    Directory of Open Access Journals (Sweden)

    Camilo Ordóñez

    2010-06-01

    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

    Full Text Available Society depends heavily on its major universities and independent research organisations for new ideas. Arguable, sustainable use of the planet will require conceptual paradigms unprecedented in human history. Educational systems, especially major universities and research organisations, must produce students in all phases of the educational continuum who are capable of transdisciplinary activities. A much larger group of such students will be required to implement these new undertakings. Until the perception of the need for transdisciplinary education becomes widespread, nothing significant is likely to happen. One major obstacle is the lack of employment for transdisciplinary individuals. A commitment to sustainable use of the planet will provide employment and make better use of increasingly scarce resources.

For these reasons it is important that the everyday operations of the Laboratory reflect a dedication to the concepts of stewardship and sustainability.

  1. Sustainable Commuting @Work

    Directory of Open Access Journals (Sweden)

    S. Castellani

    2014-10-01

    Full Text Available Local governments are seeking effective ways to promote sustainable commuting for reducing energy consumption and improving commuters’ experience. They often use so-called “Workplace Travel Plans” as policy interventions to engage work organizations as active players, promoting sustainable commuting amongst their employees. However, it remains difficult to systematically engage work organizations and commuters in such efforts for a number of reasons, ranging from preferences to constraints that they have to deal with. We aim at providing commuters, work organizations, and public administrators with tools that facilitate this engagement. In this paper, we discuss the requirements for the design of technology supporting corresponding services for commuters and work organizations and we shortly illustrate the infrastructure that we are developing to provide such services.

  9. Maintenance in sustainable manufacturing

    Directory of Open Access Journals (Sweden)

    Vladimir Stuchly

    2014-09-01

    Full Text Available Background: Sustainable development is about reaching a balance between economic, social, and environmental goals, as well as people's participation in the planning process in order to gain their input and support. For a company, sustainable development means adoption of such business strategy and actions that contribute to satisfying present needs of company and stakeholders, as well as simultaneous protection, maintenance and strengthening of human and environmental potential which will be needed in the future. This new approach forces manufacturing companies to change their previous management paradigms. New management paradigm should include new issues and develop innovative methods, practices and technologies striving for solving problem of shortages of resources, softening environment overload and enabling development of environment-friendly lifecycle of products. Hence, its realization requires updating existing production models as they are based on previously accepted paradigm of unlimited resources and unlimited regeneration capabilities. Maintenance plays a crucial role because of its impact on availability, reliability, quality and life cycle cost, thus it should be one of the main pillars of new business running model.  Material and methods: The following paper is a result of research on the literature and observation of practices undertaken by a company within maintenance area. Results and conclusions: The main message is that considering sustainable manufacturing requires considerable expanding range of analysis and focusing on supporting processes. Maintenance offers numerous opportunities of decreasing influence of business processes on natural environment and more efficient resources utilization. The goal of maintenance processes realizing sustainable development strategy is increased profitability of exploitation and optimization of total lifecycle cost without disturbing safety and environmental issues.

    2015-05-01

    Emissions reductions targets for the UK set out in the Climate Change Act for the period to 2050 will only be achieved with significant changes to the built environment, which is currently estimated to account for 50% of the UK's carbon emissions. The socio-technological nature of Civil Engineering means that this field is uniquely placed to lead the UK through such adaptations. This paper discusses the importance of interdisciplinary teaching to produce multi-faceted team approaches to sustainable design solutions. Methods for measuring success in education are often not fit for purpose, producing good students but poor engineers. Real-world failures to apply sustainable design present a serious, difficult to detect, and ultimately economically negative situation. Techniques to replace summative examinations are presented and discussed, with the aim of enhancing core technical skills alongside those required for sustainable design. Finally, the role of our future engineers in policy-making is discussed. In addition to carbon, the provision of water and food will heavily influence the work of civil engineers in the coming decades. Leadership from civil engineers with the technical knowledge and social awareness to tackle these issues will be required. This provides both opportunities and challenges for engineering education in the UK.

  17. Transforming Innovation for Sustainability

    Directory of Open Access Journals (Sweden)

    Melissa Leach

    2012-06-01

    Full Text Available The urgency of charting pathways to sustainability that keep human societies within a "safe operating space" has now been clarified. Crises in climate, food, biodiversity, and energy are already playing out across local and global scales and are set to increase as we approach critical thresholds. Drawing together recent work from the Stockholm Resilience Centre, the Tellus Institute, and the STEPS Centre, this commentary article argues that ambitious Sustainable Development Goals are now required along with major transformation, not only in policies and technologies, but in modes of innovation themselves, to meet them. As examples of dryland agriculture in East Africa and rural energy in Latin America illustrate, such "transformative innovation" needs to give far greater recognition and power to grassroots innovation actors and processes, involving them within an inclusive, multi-scale innovation politics. The three dimensions of direction, diversity, and distribution along with new forms of "sustainability brokering" can help guide the kinds of analysis and decision making now needed to safeguard our planet for current and future generations.

  8. Integrating Sustainability in Organisations: An Activity-Based Sustainability Model

    Directory of Open Access Journals (Sweden)

    Ana Rodríguez-Olalla

    2017-06-01

    Full Text Available Organisations have become interested in using integral management systems to increase their sustainable value. Although global integration models address sustainability in organisations, these models present shortcomings and limitations and do not describe how to achieve the integration of sustainability. This paper proposes an Activity-Based Sustainability (ABS integration model that complements other models from an inside-out perspective. Its assessment follows a procedure similar to that proposed by the Activity-Based Costing (ABC model of cost accounting. The model assigns impacts from activities in the value chain of a process to the objects of impact (products, services, clients, or markets that must be managed in terms of sustainability. The main limitations of the ABS model are the need to identify and describe processes, to locate every activity that constitutes the value chain, and to quantify the impacts of these activities. The ABS model is presented as an alternative to link sustainable management accounting and sustainable communication, as well as sustainable management control and sustainability assessment. It connects these sustainable elements through the bilateral identification of the linkages among skills, processes, and practices. It also links these aspects with the contribution to sustainable development and the development of competitive advantages.

    Catalysis is a key technology to achieve the objectives of sustainable (green) chemistry. After introducing the concepts of sustainable (green) chemistry and a brief assessment of new sustainable chemical technologies, the relationship between catalysis and sustainable (green) chemistry is discussed and illustrated via an analysis of some selected and relevant examples. Emphasis is also given to the concept of catalytic technologies for scaling-down chemical processes, in order to develop sustainable production processes which reduce the impact on the environment to an acceptable level that allows self-depuration processes of the living environment.

  15. Towards Life Cycle Sustainability Assessment

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Sustainability is nowadays accepted by all stakeholders as a guiding principle for both public policy making and corporate strategies. However, the biggest challenge for most organizations remains in the real and substantial implementation of the sustainability concept. The core of the implementation challenge is the question, how sustainability performance can be measured, especially for products and processes. This paper explores the current status of Life Cycle Sustainability Assessment (LCSA for products and processes. For the environmental dimension well established tools like Life Cycle Assessment are available. For the economic and social dimension, there is still need for consistent and robust indicators and methods. In addition to measuring the individual sustainability dimensions, another challenge is a comprehensive, yet understandable presentation of the results. The “Life Cycle Sustainability Dashboard” and the “Life Cycle Sustainability Triangle” are presented as examples for communication tools for both experts and non expert stakeholders.

  18. Sustainable healthcare: how to assess and improve healthcare structures' sustainability.

    Science.gov (United States)

    Buffoli, M; Capolongo, S; Bottero, M; Cavagliato, E; Speranza, S; Volpatti, L

    2013-01-01

    Sustainability is a broad and debated subject, often difficult to be defined and applied into real projects, especially when dealing with a complex scenario as the one of healthcare. Many research studies and evaluation systems have handled this topic from different perspectives, but many limits and criticalities still have to be overcome to properly cope with actual needs. The Sustainable Healthcare project has been developed through three main phases: a deep study of the state of the art, unraveling pros and cons of available sustainability scoring systems; an accurate analysis of the stakeholders network and their needs; the realization of an objective evaluation framework, through scientific methods, as the ANP. The newly developed evaluation system takes into consideration all the three pillars of sustainability, analyzing social, environmental and economic sustainability through a set of criteria, specified by measurable indicators. So the system identifies both global sustainability and specific critical areas, pointing out possible strategic solutions to improve sustainability. The evaluation is achieved through technical analyses and qualitative surveys, which eventually allow to quantitatively assess sustainability, through a sound scoring method. This study proposes an innovative evaluation method to determine the sustainability of a hospital, already existing or in the design phase, within the European context. The Sustainable Healthcare system overcomes some of the current evaluation systems' limits by establishing a multidisciplinary approach and being an easy-to-use tool. This protocol is intended to be of support in the identification of the main hospital's weaknesses and in setting priorities for implementation of the solutions.

  19. Sustainable Urban Development and Social Sustainability in the Urban Context

    Directory of Open Access Journals (Sweden)

    Faruq Ibnul Haqi

    2016-08-01

    Full Text Available Social sustainability and sustainable urban developments are major challenges across the world both developed and developing countries. In general there is a conflict between the approach of sustainable development and social sustainability in the urban context. The concept of sustainability brings a key framework for extensive literature on urban design, architecture and planning. Nevertheless there is a considerable overlap between the social dimensions of sustainability and the theories or notions, for instance the ‘sustainable societies’ that are highlighted in the midst of other aspects: social equity and justice. Such society is widely expected to offer a situation for long-term social relations and activities which are sustainable, inclusive and equitable in a wider perception of the term (environmentally, socially and economically. The method adopted to address this aim involves a content analysis of available academic literature, with focus on the planning sustainable development, built environment, social sustainability, and urban planning fields. The findings demonstrate that in spite of some opposing evidence, many studies have confirmed that there has been displacement of the debate on the term of ‘sustainability’ from ‘ecological and environmental aspects into social and economic aspects’. It is related to how the community feel safe and comfortable living in their own communities, how have they felt of proud of the place where they live. The aim of the paper is to improve our understanding of current theories and practices of planning sustainable development and discuss whether the approach of sustainable development aligns with social sustainability objectives.

  20. What is Sustainability?

    Directory of Open Access Journals (Sweden)

    John Farrington

    2010-11-01

    Full Text Available Sustainability as a policy concept has its origin in the Brundtland Report of 1987. That document was concerned with the tension between the aspirations of mankind towards a better life on the one hand and the limitations imposed by nature on the other hand. In the course of time, the concept has been re-interpreted as encompassing three dimensions, namely social, economic and environmental. The paper argues that this change in meaning (a obscures the real contradiction between the aims of welfare for all and environmental conservation; (b risks diminishing the importance of the environmental dimension; and (c separates social from economic aspects, which in reality are one and the same. It is proposed instead to return to the original meaning, where sustainability is concerned with the well-being of future generations and in particular with irreplaceable natural resources—as opposed to the gratification of present needs which we call well-being. A balance needs to be found between those two, but not by pretending they are three sides of the same coin. Although we use up natural resources at the expense of future generations, we also generate capital (including knowledge which raises future well-being. A major question is to what extent the one compensates for the other. This debate centres around the problem of substitutability, which has been cast into a distinction between ‘weak’ and ‘strong’ sustainability. It is argued that these two do not need to be in opposition but complement one another.

  13. Sustainability. An economic perspective

    Energy Technology Data Exchange (ETDEWEB)

    Elliott, Steven R. [Department of Economics and Center for Sustainable Systems Studies, Miami University, Oxford, OH (United States)

    2005-06-15

    The economic perspective of sustainability focuses on the trade off of current consumption for future consumption. This was the question that faced the economists of the late 19th century such as Malthus who noticed growth in the population outpaced that of food. Yet, Malthusian prediction of famine and disaster did not come to pass due to technological innovation. There was a substitution of created capital (machines) for natural capital (labor and land). Thus, whether created- and natural capital are substitute or complementary goods is key to sustainability. Many economists believe we can maintain current consumption and that technological innovation will take care of the needs of future generations. However other economists believe that created capital and natural capital are complementary goods; as we consume more created capital, we will also have to consume more natural capital. The relationship between natural and created capital has an impact on what policies and incentives we consider for the preservation of opportunities for future generations. If they are substitutes, current efforts need to focus on development of new technologies which will allow us to do more with less. If they are complements we need to consider efforts of preservation and conservation. We understand that we cannot have our cake and eat it too. The debate is whether we emphasize finding a new way to bake more cake, or carefully consume the cake we have.

  14. Creating sustainable performance.

    Science.gov (United States)

    Spreitzer, Gretchen; Porath, Christine

    2012-01-01

    What makes for sustainable individual and organizational performance? Employees who are thriving-not just satisfied and productive but also engaged in creating the future. The authors found that people who fit this description demonstrated 16% better overall performance, 125% less burnout, 32% more commitment to the organization, and 46% more job satisfaction than their peers. Thriving has two components: vitality, or the sense of being alive and excited, and learning, or the growth that comes from gaining knowledge and skills. Some people naturally build vitality and learning into their jobs, but most employees are influenced by their environment. Four mechanisms, none of which requires heroic effort or major resources, create the conditions for thriving: providing decision-making discretion, sharing information about the organization and its strategy, minimizing incivility, and offering performance feedback. Organizations such as Alaska Airlines, Zingerman's, Quicken Loans, and Caiman Consulting have found that helping people grow and remain energized at work is valiant on its own merits-but it can also boost performance in a sustainable way.

The aim is to conceptually consider work activity within sustainable development, and to contribute methodologically towards developing strategies for designing sustainable work systems. After a brief description of the factors and the dimensions that have contributed to the creation of ideas on sustainable development, we will put forward two main approaches for understanding work activity within the context of sustainability, these being: the durability of work activity and the development of work activities for sustainable development. Both approaches are presented and examples are given. This is followed by a discussion of the design of sustainable work systems that focuses particularly on the political and technical dimensions of project management.

    2017-02-01

    Despite substantial focus on sustainability issues in both science and politics, humanity remains on largely unsustainable development trajectories. Partly, this is due to the failure of sustainability science to engage with the root causes of unsustainability. Drawing on ideas by Donella Meadows, we argue that many sustainability interventions target highly tangible, but essentially weak, leverage points (i.e. using interventions that are easy, but have limited potential for transformational change). Thus, there is an urgent need to focus on less obvious but potentially far more powerful areas of intervention. We propose a research agenda inspired by systems thinking that focuses on transformational 'sustainability interventions', centred on three realms of leverage: reconnecting people to nature, restructuring institutions and rethinking how knowledge is created and used in pursuit of sustainability. The notion of leverage points has the potential to act as a boundary object for genuinely transformational sustainability science.

    Full Text Available The word “sustainability” is often used in business in the belief that the current ways of doing things will be able to be continued with only minor changes to balance economic development with related environmental and social issues. There are, however, immense challenges that threaten the very sustainability of our global society, let alone individual businesses or developments. A few of the most important of these challenges—population growth, clean energy supply, fresh water availability, and global climate change—are discussed. As humanity forms its collective response to these threats, it is concluded that all intelligent people, but especially scientists, have important roles to play, not only in technical innovation, but also in catalyzing political action.

  12. Financing Sustainable Development

    In the fall of 2015, world leaders adopted the most ambitious global development agenda in history. Meeting the aspiring targets of the Sustainable Development Goals will require financing far beyond traditional aid. At the same time, aid itself is under major pressure as European governments cut...... aid budgets or divert them to meet refugee and migration issues. In this context of massive global ambition and concurrent uncertainty on the future of aid, other actors and sources of development financing seem ever more critical, such as the private sector, private foundations and the BRICS....... But what are in fact the interests and modes of operation of such actors in the context of development financing, and to what extent do they align with the aims of the SDGs? And how do national governments of developing countries themselves perceive and approach these new sources of financing?...

    Groundwater extraction has facilitated significant social development and economic growth, enhanced food security and alleviated drought in many farming regions. But groundwater development has also depressed water tables, degraded ecosystems and led to the deterioration of groundwater quality, as well as to conflict among water users. The effects are not evenly spread. In some areas of India, for example, groundwater depletion has preferentially affected the poor. Importantly, groundwater in some aquifers is renewed slowly, over decades to millennia, and coupled climate–aquifer models predict that the flux and/or timing of recharge to many aquifers will change under future climate scenarios. Here we argue that communities need to set multigenerational goals if groundwater is to be managed sustainably.

    Much has been published on the success and particularly the failure of IT projects; still failures are commonplace. This prospective study focused from the outset on assessing risk of failure and addressing critical success factors. The aim was to apply existing methods in a challenging acute care hospital where success demanded rapid achievement of sustainable improvements in clinical and administrative processes. The implementations were part of the English National Programme for IT. The desired outcomes required the integration of accepted tools and techniques to provide a pragmatic approach to systems implementation: Lean, Six Sigma, PRINCE2 and Benefits Management. The outcome and further insights into success and failure of IT projects in healthcare are described. In particular lessons are identified related to the business need for the project and the successful achievement of the required benefits and business change.

    Following a series of measures taken to foster a green policy for the Laboratory, CERN Management has recently appointed an Energy Issues Coordinator. While it's hard to imagine magic solutions that would substantially decrease the energy consumption of the research accelerators, it is certainly within our reach to re-use thermal “waste” energy and to optimise infrastructure to become more sustainable and eco-friendly. Real eco-projects are in the making.   CERN's electricity consumption is considerable, equivalent to a third of Geneva's. Over 95% is used by the accelerators and other research facilities. CERN also consumes gas for heating, fuel and gas for cars, and water for sanitary use and accelerator cooling. “It's our responsibility to keep our energy consumption and hence our impact on the environment as low as possible,” says Helfried Burckhart, recently appointed as CERN’s Energy Issues Coordinator. &am...

This perspective may contribute to the study of transition processes that so far have not studied citizens' roles in depth. Based on discussions of theories on transition and institutional capacity building, the article...... the intermediary actors facilitate citizens' participatory processes in sustainable urban transitions, and the paper explores the concept of institutional capacity building as a way to develop learning processes and new practises? The aim is to analyse approaches of creating platforms for involving citizens...... discusses the mobilisation of citizens through social learning processes and how the develop-ment of new platforms plays a part in societal transitions. Empirically, the article is based on case studies from Denmark of local environmental centres, green guides etc. that have per-formed innovative forms...

    A quarter of humanity's current energy consumption is used for transportation (1). Low-temperature hydrogen fuel cells offer much promise for replacing this colossal use of fossil fuels with renewables; these fuel cells produce negligible emissions and have a mileage and filling time equal...... to a regular gasoline car. However, current fuel cells require 0.25 g of platinum (Pt) per kilowatt of power (2) as catalysts to drive the electrode reactions. If the entire global annual production of Pt were devoted to fuel cell vehicles, fewer than 10 million vehicles could be produced each year, a mere 10......% of the annual automotive vehicle production. Lowering the Pt loading in a fuel cell to a sustainable level requires the reactivity of Pt to be tuned so that it accelerates oxygen reduction more effectively (3). Two reports in this issue address this challenge (4, 5)....

    Full Text Available Urban water management has somewhat changed since the publication of The Sustainable Drainage System (SuDS Manual in 2007 [1], transforming from building traditional sewers to implementing SuDS, which are part of the best management practice techniques used in the USA and seen as contributing to water-sensitive urban design in Australia. Most SuDS, such as infiltration trenches, swales, green roofs, ponds, and wetlands, address water quality and quantity challenges, and enhance the local biodiversity while also being acceptable aesthetically to the public. Barriers to the implementation of SuDS include adoption problems, flood and diffuse pollution control challenges, negative public perception, and a lack of decision support tools addressing, particularly, the retrofitting of these systems while enhancing ecosystem services.
