    Low back pain (LBP) is a world health problems and a major cause of disability. The study is to determine the correlation between pain intensity and quality of life (QoL) in patients with chronic LBP. This study was a descriptive, analytical research with the cross sectional design. Twenty-nine chronic LBP outpatients that have visited the Neurology Clinic of Adam Malik General Hospital Medan. Patients from July to November 2015 were selected by consecutive sampling. A questionnaire and interview are asking the information about subjects’ characteristics, diagnosis, medical history, pain intensity and quality of life-based on WHO QoL criteria were used to collect the data. Using Spearman correlation test, we found correlation among VAS and physical function (p<0.001, r=-0.606), limitations due to physical problems (p<0.001, r=-0.837), limitations due to emotional problems (p=0.007, r=-0,477), vitality (p=0.021, r=-0.380), social function (p=0.015, r=-0.403), the feeling of pain (p=0.003, r=-0.499) and general health (p=0.040, r=-0.330). On the other hand, there was no correlation between VAS and mental health (p=0.110, r=-0.235). We concluded that pain intensity in outpatients with chronic LBP in the Neurology Clinic at Adam Malik General Hospital Medan correlates with the patients’ quality of life.

    Full Text Available Abstract Background In the treatment of chronic back pain, cognitive methods are attracting increased attention due to evidence of effectiveness similar to that of traditional therapies. The purpose of this study was to compare the effectiveness of performing a cognitive intervention based on a non-injury model with that of a symptom-based physical training method on the outcomes of low back pain (LBP, activity limitation, LBP attitudes (fear-avoidance beliefs and back beliefs, physical activity levels, sick leave, and quality of life, in chronic LBP patients. Methods The study was a pragmatic, single-blind, randomised, parallel-group trial. Patients with chronic/recurrent LBP were randomised to one of the following treatments: 1. Educational programme : the emphasis was on creating confidence that the back is strong, that loads normally do not cause any damage despite occasional temporary pain, that reducing the focus on the pain might facilitate more natural and less painful movements, and that it is beneficial to stay physically active. 2. Individual symptom-based physical training programme : directional-preference exercises for those centralising their pain with repetitive movements; 'stabilising exercises' for those deemed 'unstable' based on specific tests; or intensive dynamic exercises for the remaining patients. Follow-up questionnaires (examiner-blinded were completed at 2, 6 and 12 months. The main statistical test was an ANCOVA adjusted for baseline values. Results A total of 207 patients participated with the median age of 39 years (IQR 33-47; 52% were female, 105 were randomised to the educational programme and 102 to the physical training programme. The two groups were comparable at baseline. For the primary outcome measures, there was a non-significant trend towards activity limitation being reduced mostly in the educational programme group, although of doubtful clinical relevance.

    Full Text Available LBP management is complex and costly, with socio-economic and medical implications. Disabilities caused by painful back disorders represent a major problem of absenteeism from work (1. The prevalence of LBP in the active population (25-64 years old is increasing. There are studies (2 showing that between 60 and 80% of people may suffer from back pain during their lifetime and 5% may present radiculopathy, the rest of them being diagnosed with nonspecific LBP. Of those, approximately 30% will be diagnosed with chronic LBP. More recent studies (3 show that the prevalence of LBP appearance for one year is of 65%, for the entire life, it is of 84% and for present day, of 33%. In the developed countries, 1 in 5 adults may experience symptoms of LBP, the number of these reaching 40% in England, Denmark, while in the US, the value is of 7-25%. Approximately 80-90% of patients with LBP are diagnosed with “non-specific” low back pain and 3% will require surgery. LBP is a common condition, representing 1/3 of rheumatic complaints. This condition interests both the young people and the adult one. Therefore, 25% of people aged between 30 and 50 years old consider LBP as the most frequent cause of work incapacity in the people below 45 years old. Risk factors for the occurrence of LBP are: occupational (heavy physical work, lifting weights, torsional movement of the trunk, prolonged standing, sedentary lifestyle, psychological (depression, anxiety, fear of movement, socio-demographic characteristics (weight, age, incorrect posture, lifestyle, educational level, smoking, family problems, low incomes. Medical rehabilitation in LBP involves combating pain and inflammation, improving statics and lumbosacral spine dynamics, improving paravertebral and abdominal muscle strength, gait rehabilitation. These objectives are achieved by pharmacological methods and physical-kinetic therapy. The aim of the study was to emphasize the importance of physical therapy in

    Full Text Available Video segmentation is the basis for content-based video retrieval, object recognition, object tracking, and video compression. This paper proposes a kind of novel and easy spatial-temporal LBP coding method, using the spatial-temporal 2 × 2 × 2 neighborhood clique to encode the changes in a video. Based on the coding method, a scheme of video segmentation is developed. Compared to the traditional segmentation method, its distinguished advantage is that it does not need to construct the background model and is simple in computation. Experimental results indicate that this new algorithm can give satisfying segmentation results.

    Alexithymia is a clinical phenomenon that has been found to occur with some frequency in psychosomatic disorders. Its prevalence in psychosomatic patients suggests that it could be observed in chronic pain patients as well. The present study examines the incidence of alexithymia in chronic pain patients as assessed by the Archetypal Test with Nine Elements (AT9). Patients' scores on the AT9 (SAT9) were examined in conjunction with McGill Pain Questionnaire (MPQ) data, MMPI subscale scores, and patient data. There were no significant relationships found between SAT9, MMPI, and MPQ scores. These observations are examined with reference to the nature of the assessment instruments used. Implications of these observations for theory and therapy are discussed.

    Using LBP (local binary pattern) to extract texture feature in the area of image recognition and retrieval has achieved good results. LSH (locality sensitive hashing) in the information retrieval, especially to solve the ANN (approximate nearest neighbor) problem has a more important Status. LSH has a solid theoretical basis and excellent performance in high-dimensional data space. Under the trend of cloud computing and Big Data, this paper proposes an image retrieval algorithm based on LBP and LSH. Firstly, LBP is used to extract the texture feature vector of the image. Then, the LBP texture feature is reduced dimensionally and indexed into different buckets using LSH. Finally, the image corresponding to the index value in the bucket is extracted for second retrieval by using LBP. This algorithm can adapt to the massive image retrieval and ensures the high accuracy of the image retrieval and reduces the time complexity. This algorithm is of great significance.

    Full Text Available Abstract Background Acupuncture is a frequently used but controversial adjunct to the treatment of chronic low back pain (LBP. Acupuncture is now considered to be effective for chronic LBP and health care systems are pressured to make a decision whether or not acupuncture should be covered. It has been suggested that providing such services might reduce the use of other health care services. Therefore, we explored factors associated with acupuncture treatment for LBP and the relation of acupuncture with other health care services. Methods This is a post hoc analysis of a longitudinal prospective cohort study. General practitioners (GPs recruited consecutive adult patients with LBP. Data on physical function, subjective mood and utilization of health care services was collected at the first consultation and at follow-up telephone interviews for a period of twelve months. Results A total of 179 (13 % out of 1,345 patients received acupuncture treatment. The majority of those (59 % had chronic LBP. Women and elderly patients were more likely to be given acupuncture. Additional determinants of acupuncture therapy were low functional capacity and chronicity of pain. Chronic (vs. acute back pain OR 1.6 (CL 1.4–2.9 was the only significant disease-related factor associated with the treatment. The strongest predictors for receiving acupuncture were consultation with a GP who offers acupuncture OR 3.5 (CL 2.9–4.1 and consultation with a specialist OR 2.1 (CL 1.9–2.3. After adjustment for patient characteristics, acupuncture remained associated with higher consultation rates and an increased use of other health care services like physiotherapy. Conclusion Receiving acupuncture for LBP depends mostly on the availability of the treatment. It is associated with increased use of other health services even after adjustment for patient characteristics. In our study, we found that receiving acupuncture does not offset the use of other health care resources

    Full Text Available Objective: To identify the current evidence for acute low back pain (LBP treatment techniques and to amalgamate this information into a clinically applicable algorithm for South African physiotherapists.Study design: Systematic review.Methods: Computerized bibliographical databases were systematically searched during September 2006 and October 2006 for primary and secondary research reporting on the efficacy of various physiotherapeutic treatment techniques for acute LBP. A search for clinical guidelines regarding acute LBP was also undertaken. Evidence levels were allocated to the primary and secondary research retrieved. Results: Twenty-one systematic reviews, four randomized controlled trials and eleven clinical guidelines were included in this review. There is Level 1 evidence that advice to stay active, McKenzie preferential exercises and spinal manipulative therapy (up to six weeks is beneficial in the initial treatment of acute LBP. There is level 2 evidence that stability exercises, dry needling, heat wrap with exercises, cognitive behavioural therapy, printed patient education, massage (with education and exercises, and lifestyle modification might be potentially beneficial in the treatment of acute LBP. There is level 1 evidence that bed rest should not be recommended for simple acute LBP.  Should a patient not resolve in six weeks, red and yellow flags should be re-assessed, or patient should be referred to a specialist. Outcome: Based on the current evidence, a composite algorithm was developed to assist South African physiotherapists when making treatment decisions for acute LBP. Conclusion: There seems to be a lack of evidence for the efficacy of common treatment techniques used by physiotherapists in the management of acute LBP, indicating an urgent need for physiotherapy-specific, high-quality clinical trials. It is suggested that the evidence-based algorithm that has been developed, be used in the management of acute LBP to

    Low back pain (LBP) is the leading cause of disability worldwide. Of those patients who present to primary care with acute LBP, 40% continue to report symptoms 3 months later and develop chronic LBP. Although it is possible to identify these patients early, effective interventions to improve their outcomes are not available. This double-blind (participant/outcome assessor) randomised controlled trial will investigate the efficacy of a brief educational approach to prevent chronic LBP in 'at-risk' individuals. Participants will be recruited from primary care practices in the Sydney metropolitan area. To be eligible for inclusion participants will be aged 18-75 years, with acute LBP (free period and at-risk of developing chronic LBP. Potential participants with chronic spinal pain and those with suspected serious spinal pathology will be excluded. Eligible participants who agree to take part will be randomly allocated to receive 2×1 h sessions of pain biology education or 2×1 h sessions of sham education from a specially trained study physiotherapist. The study requires 101 participants per group to detect a 1-point difference in pain intensity 3 months after pain onset. Secondary outcomes include the incidence of chronic LBP, disability, pain intensity, depression, healthcare utilisation, pain attitudes and beliefs, global recovery and recurrence and are measured at 1 week post-intervention, and at 3, 6 and 12 months post LBP onset. Ethical approval was obtained from the University of New South Wales Human Ethics Committee in June 2013 (ref number HC12664). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at international conference meetings. https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12612001180808.

    Pathomorphological study of trephinobiopsy specimens from 129 patients with lymphoproliferative and myeloproliferative diseases was carried out over the course of chemotherapy. Combinations of initial and manifest myelofibrosis (loose network of reticulin fibers and extensive network of reticulin and collagen fibers, respectively) predominated at the debut of chronic myeloid leukemia, chronic lymphoid leukemia, and multiple myeloma. Manifest myelofibrosis was detected in patients with chronic myeloid leukemia without hematological response (failure of normalization of hematological values) and in patients with progressing and relapsing multiple myeloma. Combinations of foci of initial and manifest myelofibrosis were most incident in patients with progressing and relapsing chronic lymphoid leukemia. The incidence of myelofibrosis was higher in patients with multiple myeloma and chronic lymphoid leukemia progression and relapses and in patients with chronic myeloid leukemia without hematological response than at the disease debut and in case of response to chemotherapy. The response to chemotherapy in patients with chronic myeloid leukemia and chronic lymphoid leukemia was associated with a decrease in the incidence of myelofibrosis. In patients with multiple myeloma responding to chemotherapy, the incidence of myelofibrosis did not change in comparison with the disease debut.

    Objective: Face Recognition is one of the widely application of image processing. Corresponding two-dimensional limitations, such as the pose and illumination changes, to a certain extent restricted its accurate rate and further development. How to overcome the pose and illumination changes and the effects of self-occlusion is the research hotspot and difficulty, also attracting more and more domestic and foreign experts and scholars to study it. 3D face recognition fusing shape and texture descriptors has become a very promising research direction. Method: Our paper presents a 3D point cloud based on mesh local binary pattern grid (Mesh-LBP), then feature extraction for 3D face recognition by fusing shape and texture descriptors. 3D Mesh-LBP not only retains the integrity of the 3D geometry, is also reduces the need for recognition process of normalization steps, because the triangle Mesh-LBP descriptor is calculated on 3D grid. On the other hand, in view of multi-modal consistency in face recognition advantage, construction of LBP can fusing shape and texture information on Triangular Mesh. In this paper, some of the operators used to extract Mesh-LBP, Such as the normal vectors of the triangle each face and vertex, the gaussian curvature, the mean curvature, laplace operator and so on. Conclusion: First, Kinect devices obtain 3D point cloud face, after the pretreatment and normalization, then transform it into triangular grid, grid local binary pattern feature extraction from face key significant parts of face. For each local face, calculate its Mesh-LBP feature with Gaussian curvature, mean curvature laplace operator and so on. Experiments on the our research database, change the method is robust and high recognition accuracy.

    High-normal albuminuria is an important risk factor for incident chronic kidney disease in diabetic populations, in contrast to an uncertain association in nondiabetic populations. This study aimed to reveal the relationship between high-normal albuminuria and incident chronic kidney disease in a Japanese nondiabetic population. A 10-year follow-up retrospective cohort study was performed involving 1378 Japanese men (mean age 44 ± 5.3 years) without chronic kidney disease and diabetes mellitus. Chronic kidney disease was diagnosed as either estimated glomerular filtration rate chronic kidney disease over the 10-year follow-up period. Median annual estimated glomerular filtration rate decline showed a deterioration with increasing quartiles of baseline albumin-to-creatinine ratio (P = 0.004). Participants who had a baseline albumin-to-creatinine ratio in the highest quartile (5.9-28.9 mg/g) were more likely to develop micro- or macroalbuminuria (odds ratio: 16.23, 95% confidence interval 6.56-54.03), chronic kidney disease (odds ratio: 2.48, 95% confidence interval 1.64-3.82), and hypertension (odds ratio 2.06, 95% confidence interval 1.30-3.31), but not diabetes mellitus compared with those who had an albumin-to-creatinine ratio in the lowest quartile (1.3-3.6 mg/g) after adjustment for potential confounders. High-normal albuminuria was associated with incident chronic kidney disease in this Japanese nondiabetic male population.

    In this paper, we propose DGDB-LBP, a local binary pattern descriptor based on the pixel blocks in the dominant gradient direction. Differing from traditional LBP and its variants, DGDB-LBP encodes by comparing the main gradient magnitude of each block rather than the single pixel value or the average of pixel blocks, in doing so, it reduces the influence of noise on pollen images and eliminates redundant and non-informative features. In order to fully describe the texture features of pollen images and analyze it under multi-scales, we propose a new sampling strategy, which uses three types of operators to extract the radial, angular and multiple texture features under different scales. Considering that the pollen images have some degree of rotation under the microscope, we propose the adaptive encoding direction, which is determined by the texture distribution of local region. Experimental results on the Pollenmonitor dataset show that the average correct recognition rate of our method is superior to other pollen recognition methods in recent years.

    To determine the incidence of and associated risk factors for uveitis after cataract surgery. A total of 17,757 eyes were identified and records of 42 eyes that developed uveitis and 2320 eyes that did not were reviewed. Postsurgical uveitis was defined as persistent inflammation for ≥ 6 months after surgery. Forty-two eyes of 35 patients developed uveitis (0.24%). Eleven patients underwent consecutive cataract surgery but developed unilateral uveitis, and intraoperative complications occurred in 55% of uveitic eyes compared to 0% in fellow eyes (p < 0.05). Median duration of inflammation was 8 and 11.5 months in eyes with and without vitrectomy (p < 0.05). Intraocular complications occurred in 44 and 8.3% of eyes that did and did not develop uveitis, respectively (p = 0.01). Postsurgical uveitis developed after approximately 1 in 400 cataract surgeries and occurred more frequently in eyes experiencing intraoperative complications.

    The aim was to systematically review published articles that reported the incidence of chronic kidney disease among people with diabetes. A systematic literature search was performed using MEDLINE, Embase and CINAHL databases. The titles and abstracts of all publications identified by the search were reviewed and 10 047 studies were retrieved. A total of 71 studies from 30 different countries with sample sizes ranging from 505 to 211 132 met the inclusion criteria. The annual incidence of microalbuminuria and albuminuria ranged from 1.3% to 3.8% for Type 1 diabetes. For Type 2 diabetes and studies combining both diabetes types, the range was from 3.8% to 12.7%, with four of six studies reporting annual rates between 7.4% and 8.6%. In studies reporting the incidence of eGFR Disease (MDRD) equation, apart from one study which reported an annual incidence of 8.9%, the annual incidence ranged from 1.9% to 4.3%. The annual incidence of end-stage renal disease ranged from 0.04% to 1.8%. The annual incidence of microalbuminuria and albuminuria is ~ 2-3% in Type 1 diabetes, and ~ 8% in Type 2 diabetes or mixed diabetes type. The incidence of developing eGFR kidney disease, there was only modest variation in incidence rates. These findings may be useful in clinical settings to help understand the risk of developing kidney disease among those with diabetes. © 2017 Diabetes UK.

    Background Previous studies on the relation of chronic bronchitis to incident airflow limitation and all-cause mortality have provided conflicting results, with positive findings reported mainly by studies that included populations of young adults. We sought to determine whether having chronic cough and sputum production in the absence of airflow limitation is associated with onset of airflow limitation, all-cause mortality, and serum levels of CRP and IL-8, and whether subjects’ age influences these relations. Methods We identified 1412 participants in the long-term Tucson Epidemiological Study of Airway Obstructive Disease who at enrollment (1972–73) were 21–80 years old and had FEV1/FVC≥70% and no asthma. Chronic bronchitis was defined as cough and phlegm production on most days for ≥three months in ≥two consecutive years. Incidence of airflow limitation was defined as the first follow-up survey with FEV1/FVC<70%. Serum IL-8 and CRP levels were measured in cryopreserved samples from the enrollment survey. Results After adjusting for covariates, chronic bronchitis at enrollment increased significantly the risk for incident airflow limitation and all-cause mortality among subjects <50 years old (Hazard Ratios, 95% CI: 2.2, 1.3–3.8; and 2.2, 1.3–3.8; respectively), but not among subjects ≥50 years old (0.9, 0.6–1.4; and 1.0, 0.7–1.3). Chronic bronchitis was associated with increased IL-8 and CRP serum levels only among subjects <50 years old. Conclusions Among adults <50 years old, chronic bronchitis unaccompanied by airflow limitation may represent an early marker of susceptibility to the effects of cigarette smoking on systemic inflammation and long-term risk for chronic obstructive pulmonary disease and all-cause mortality.

  15. The mesh-LBP: a framework for extracting local binary patterns from discrete manifolds.

    2015-01-01

    In this paper, we present a novel and original framework, which we dubbed mesh-local binary pattern (LBP), for computing local binary-like-patterns on a triangular-mesh manifold. This framework can be adapted to all the LBP variants employed in 2D image analysis. As such, it allows extending the related techniques to mesh surfaces. After describing the foundations, the construction and the main features of the mesh-LBP, we derive its possible variants and show how they can extend most of the 2D-LBP variants to the mesh manifold. In the experiments, we give evidence of the presence of the uniformity aspect in the mesh-LBP, similar to the one noticed in the 2D-LBP. We also report repeatability experiments that confirm, in particular, the rotation-invariance of mesh-LBP descriptors. Furthermore, we analyze the potential of mesh-LBP for the task of 3D texture classification of triangular-mesh surfaces collected from public data sets. Comparison with state-of-the-art surface descriptors, as well as with 2D-LBP counterparts applied on depth images, also evidences the effectiveness of the proposed framework. Finally, we illustrate the robustness of the mesh-LBP with respect to the class of mesh irregularity typical to 3D surface-digitizer scans.

    Pelvic floor disorders cover pathologies of which physiopathology is not well understood. However cases get prevalent with an ageing population. Within the context of a project aiming at modelization of the dynamics of pelvic organs, we have developed an efficient segmentation process. It aims at alleviating the radiologist with a tedious one by one image analysis. From a first contour delineating the uterus-vagina set, the organ border is tracked along a dynamic mri sequence. The process combines movement prediction, local intensity and texture analysis and active contour geometry control. Movement prediction allows a contour intitialization for next image in the sequence. Intensity analysis provides image-based local contour detection enhanced by local binary pattern (lbp) texture descriptors. Geometry control prohibits self intersections and smoothes the contour. Results show the efficiency of the method with images produced in clinical routine.

    2011-03-01

    In this research study, a system to support medical analysis of intestinal contractions by processing WCE images is presented. Small intestine contractions are among the motility patterns which reveal many gastrointestinal disorders, such as functional dyspepsia, paralytic ileus, irritable bowel syndrome, bacterial overgrowth. The images have been obtained using the Wireless Capsule Endoscopy (WCE) technique, a patented, video colorimaging disposable capsule. Manual annotation of contractions is an elaborating task, since the recording device of the capsule stores about 50,000 images and contractions might represent only the 1% of the whole video. In this paper we propose the use of Local Binary Pattern (LBP) combined with the powerful textons statistics to find the frames of the video related to contractions. We achieve a sensitivity of about 80% and a specificity of about 99%. The achieved high detection accuracy of the proposed system has provided thus an indication that such intelligent schemes could be used as a supplementary diagnostic tool in endoscopy.

    The aim of this community-based study is to ascertain the effect of different obesity phenotypes on the incidence of chronic kidney disease in Iranian adults. A prospective cohort study, the Tehran Lipid Glucose Study (TLGS). Adults aged ≥ 20 years with a mean age of 40.38 years (54.8% female) who were free from chronic kidney disease (CKD) at baseline (phase 1) and were followed up at 3 time stages (phases 2, 3, and 4) for a mean duration of 9.4 years to assess the risk for CKD. Obesity phenotypes. Incidence of chronic kidney disease. Glomerular filtration rate (GFR) was estimated from the simplified equation developed using data from the Modification of Diet in Renal Disease (MDRD) Study. CKD events occurred in 1162 participants. The prevalence of the 2 known obesity phenotypes (metabolically obese normal weight [MONW] and metabolically healthy but obese [MHO]) in the overall population was 3.5% and 8.8%, respectively. According to Kaplan-Meier curves, rates of freedom from CKD in the MHO and MONW obesity phenotypes were 75.3% and 60.6%, respectively (p obesity phenotype were 1.14 (95% confidence interval [CI], 0.91-1.43) and 1.43 (95% CI, 1.09-1.88), respectively. After further adjustment for confounder variables (model 2), multivariate-adjusted hazard ratios for CKD for participants with MHO or MONW obesity phenotypes were 1.23 (95% CI, 0.93-1.62) and 1.43 (95% CI, 1.08-1.90), respectively. Adults with the MONW obesity phenotype compared to those with MHO obesity phenotype have a higher risk for incidence of CKD. The results indicate that having a normal weight is not the only factor to protect against incidence of CKD.

    Overt and subclinical hypothyroidism are associated with higher levels of serum creatinine and with increased risk of chronic kidney disease (CKD). The prospective association between thyroid hormones and kidney function in euthyroid individuals,however, is largely unexplored. We conducted a prospective cohort study in 104 633 South Korean men and women who were free of CKD and proteinuria at baseline and had normal thyroid hormone levels and no history of thyroid disease or cancer. At each annual or biennial follow-up visit, thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxin (FT4) levels were measured by radioimmunoassay. The study outcome was incident CKD, defined as an estimated glomerular filtration rate (eGFR)<60 ml/min/1.73 m2 based on the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. After a median follow-up of 3.5 years, 1032 participants developed incident CKD.There was a positive association between high-normal levels of TSH and increased risk of incident CKD. In fully-adjusted models including baseline eGFR, the hazard ratio comparing the highest vs the lowest quintiles of TSH was 1.26 [95% confidence interval (CI) 1.02 to 1.55; P for linear trend=0.03]. In spline models, FT3 levels below 3 pg/ml were also associated with increased risk of incident CKD. There was no association between FT4 levels and CKD. In a large cohort of euthyroid men and women, high levels of TSH and low levels of FT3, even within the normal range, were modestly associated with an increased risk of incident CKD.

However, few studies have used spirometry to investigate its incidence, especially in Asia. In the present study, we analyzed the incidence and risk factors of COPD using a community cohort database in Korea. Patients and methods: The study included 6,517 subjects aged 40–69 years from the Ansung–Ansan cohort database I–III (2001–2006. We calculated the crude incidence rate and the standardized incidence rate corrected for the Korean general population and the world population with COPD. We also determined the relative risks (RRs for incident COPD and the attributable risks. Results: In total, 329 new COPD cases were diagnosed during follow-up. The overall crude incidence rate per 100,000 person-years was 1,447. The standardized incidence rate corrected for the Korean general population was 1,550; this value was higher in men and increased with increasing age. Risk factors for incident COPD were age ≥60 years (adjusted RR [aRR] =2.52 vs age <60 years, male sex (aRR =2.02 vs female, heavy smoking (≥20 pack-years; aRR =2.54 vs never smoker, and lowest income group (first quartile; aRR =2.03 vs fourth quartile. The adjusted attributable risk was highest for education level of high school or lower (44.9%, followed by smoking history (25.8%, income (22.9%, and sex (12.0%. Conclusion: In Korea, 15.5/1,000 people are diagnosed with COPD annually. The incidence rate increases with increasing age, heavier smoking, and decreasing income, with a higher rate in men than in women.

    Rheumatoid arthritis is associated with reduced kidney function, possibly due to chronic inflammation or the use of nephrotoxic therapies. However, little is known about the effects of using the newer novel non-nephrotoxic biologic agents on the risk of incident chronic kidney disease (CKD). To study this we used a cohort of 20,757 United States veterans diagnosed with rheumatoid arthritis with an estimated glomerular filtration rate (eGFR) of 60 mL/min/1.73m 2 or more, recruited between October 2004 and September 2006, and followed through 2013. The associations of biologic use with incident CKD (eGFR under 60 with a decrease of at least 25% from baseline, and eGFR under 45 mL/min/1.73m 2 ) and change in eGFR (biologic treatment, using Cox models and multinomial logistic regression models, respectively. Among 20,757 patients, 4,617 started biologic therapy. In the propensity-matched cohort, patients treated (versus not treated) with biologic agents had a lower risk of incident CKD (hazard ratios 0.95, 95% confidence interval [0.82-1.10] and 0.71 [0.53-0.94] for decrease in eGFR under 60 and under 45 mL/min/1.73m 2 , respectively) and progressive eGFR decline (multinomial odds ratios [95% CI] for eGFR slopes biologic administration in patients treated with biologics (-1.0 versus -0.4 [mL/min/1.73m 2 /year] before and after biologic use). Thus, biologic agent administration was independently associated with lower risk of incident CKD and progressive eGFR decline. Published by Elsevier Inc.

    Chronic postsurgical pain (CPSP) is a common complication of surgery with high impact on quality of life. Peripheral and central sensitization caused by enhanced and prolonged afferent nociceptive input are considered important mechanisms for the development of CPSP. This case-control study investigated whether epidural analgesia is associated with a reduced incidence of CPSP after open abdominal surgery. Six months after surgery, Short-Form-36 Health Survey (SF-36) pain scores, possible predictors of chronic pain, and quality of life were assessed. Patients treated with epidural analgesia in combination with general anesthesia (epidural group, N = 51) were compared to patients undergoing matched surgical procedures receiving general anesthesia alone (GA-group, N = 50). Multivariate analysis was performed by logistic regression analysis. Twenty-six (25.7%) patients experienced chronic pain, 9 in the epidural group (17.6%), 17 in the GA-group (34%), crude odds ratio (OR) 0.42 (95% confidence interval (CI) 0.16 to 1.05). After adjustment for the most prominent predictors of CPSP, such as age, sex, pre-operative pain, and acute postoperative pain, the OR for chronic pain in the epidural group was 0.19 (95% CI 0.05 to 0.76). Patients with CPSP reported a significantly lower quality of life compared to patients without CPSP (SF-36 total score median (IQR) 39.2 (27.2 to 56.7) vs. 84.3 (69.9 to 92.5, P abdominal surgery.

    Full Text Available Lipopolysaccharide-binding protein (LBP is closely associated with many metabolic disorders. However, no study has been done to explore the relationship between LBP and polycystic ovary syndrome (PCOS. The objective of this study was to investigate whether the serum LBP level is elevated and associated with insulin resistance (IR in PCOS.In this cross-sectional study, 117 PCOS patients and 121 age-matched controls were recruited. Hyperinsulinemic-euglycemic clamp was performed with an expression of M value for insulin sensitivity. Fasting serum samples were collected to detect LBP, lipids, insulin, sex hormones and high sensitive C reactive protein (hs-CRP. Pearson's correlation and multiple linear regression was used to analyze the associations between M value and LBP level.The study was performed in a clinical research center.Compared with controls, PCOS subjects had a significantly higher LBP concentration (33.03±14.59 vs. 24.35±10.31 μg/ml, p<0.001, and lower M value (8.21±3.06 vs. 12.31±1.72 mg/min/kg, p<0.001. Both in lean and overweight/obese individuals, serum LBP level was higher in PCOS subjects than that in controls. M value was negatively correlated with body mass index (BMI, fasting serum insulin, triglycerides, low-density lipoprotein cholesterol (LDL-c, free testosterone, high sensitive C reactive protein (hs-CRP and LBP, whereas positively correlated with high-density lipoprotein cholesterol (HDL-c and sex hormone binding globulin (SHBG. Serum LBP level was associated with M value after adjusting for BMI, fasting serum insulin, SHBG, as well as hs-CRP.Serum LBP level significantly is elevated in PCOS, and is independently associated with IR in PCOS.

    Seizures can occur in patients who have surgery for a chronic subdural hematoma. However, the incidence of seizures and their impact on the clinical course of patients in the perioperative period is not well known. In this retrospective study, we reviewed 161 cases of patients treated for chronic subdural hematoma in our institution. The surgical procedures consisted in trephine craniotomy in 156 cases, burr-hole craniotomy in three cases, and bone flap craniotomy in two cases. All the patients had systematic antiepileptic drug prophylaxis. In our patients' population, the incidence of seizures was 10.6% before surgery and 14.9% after surgery. Low initial score on the Glasgow Coma Scale (Pcognitive impairment (P=0.005) were associated with a higher rate of postoperative seizures. In our study, the mortality rate was 14.9%. Low initial score on the Glasgow Coma Scale (P=0.068) and postoperative seizures (P=0.002) were associated with a higher mortality rate. We have shown that patients suffering from seizures may have worse outcome. The benefit of a systematic perioperative prophylaxis using antiepileptic drugs has to be evaluated.

    Full Text Available Despite decades of research, a full understanding of chronic kidney disease (CKD-end stage renal disease (ESRD progression remains elusive. The common consensus is a predictable, linear, progressive and time-dependent decline of CKD to ESRD. Acute kidney injury (AKI on CKD is usually assumed to be transient, with recovery as the expected outcome. AKI-ESRD association in current nephrology literature is blamed on the so-called "residual confounding." We had previously described a relationship between AKI events and rapid onset yet irreversible ESRD happening in a continuum in a high-risk CKD cohort. However, the contribution of the syndrome of rapid onset-ESRD (SORO-ESRD to incident United States ESRD population remained conjectural. In this retrospective analysis, we analyzed serum creatinine trajectories of the last 100 consecutive ESRD patients in 4 Mayo Clinic chronic hemodialysis units to determine the incidence of SORO-ESRD. Excluding 9 patients, 31 (34% patients, including two renal transplant recipients, had SORO-ESRD: 18 males and 13 females age 72 (range 50-92 years. Precipitating AKI followed pneumonia (8, acutely decompensated heart failure (7, pyelonephritis (4, post-operative (5, sepsis (3, contrast-induced nephropathy (2, and others (2. Time to dialysis was shortest following surgical procedures. Concurrent renin angiotensin aldosterone system blockade was higher with SORO-ESRD - 23% versus 5%, P = 0.0113. In conclusion, SORO-ESRD is not uncommon among the incident general US ESRD population. The implications for ESRD care planning, AV-fistula-first programs, general CKD care and any associations with renal ageing/senescence warrant further study.

    Full Text Available Abstract Background Following reports of high prevalence of low back pain (LBP in young physiotherapists 171819202122, we investigated whether LBP was a problem for undergraduate physiotherapy students. Method Physiotherapy students enrolled in one Australian tertiary institution completed a validated self-administered questionnaire in April 2001, seeking information on LBP prevalence (lifetime, 12 month, one-month, one-week, and its risk factors. The survey incorporated the Nordic back questionnaire, questions on common risks for LBP, and purpose-built questions regarding educational exposures. Univariate logistic regression models were applied to test associations. Results and Discussion 72% students responded. LBP prevalence was 69% (lifetime, 63% (12-month, 44% (one-month, 28% (one-week. The risk of LBP increased significantly for students once they completed first year. Being aged 20 or 21 years (final year students was significantly associated with all measures of LBP, compared with the youngest students. Exposure to tertiary study of greater than two years was associated with lifetime, 12 month and one-month LBP prevalence. Spending more than 20 hours in the past month 'sitting looking down' was significantly associated with one-month LBP prevalence. Similar exposure to 'treating patients' was significantly associated with one-month and one-week LBP prevalence. Conclusions Physiotherapy students should be alerted to the likelihood of LBP and is potential causes during their training, so that they enter the workforce with reduced risk of LBP. The potential for other undergraduate students to suffer LBP should also be considered.

    Toll-like receptor 4 (TLR4) together with MD2, one of the key pattern recognition receptors for a pathogen-associated molecular pattern, activates innate immunity by recognizing lipopolysaccharide (LPS) of Gram-negative bacteria. Although LBP and CD14 catalyze LPS transfer to the TLR4/MD2 complex, the detail mechanisms underlying this dynamic LPS transfer remain elusive. Using negative-stain electron microscopy, we visualized the dynamic intermediate complexes during LPS transfer-LBP/LPS micelles and ternary CD14/LBP/LPS micelle complexes. We also reconstituted the entire cascade of LPS transfer to TLR4/MD2 in a total internal reflection fluorescence (TIRF) microscope for a single molecule fluorescence analysis. These analyses reveal longitudinal LBP binding to the surface of LPS micelles and multi-round binding/unbinding of CD14 to single LBP/LPS micelles via key charged residues on LBP and CD14. Finally, we reveal that a single LPS molecule bound to CD14 is transferred to TLR4/MD2 in a TLR4-dependent manner. These discoveries, which clarify the molecular mechanism of dynamic LPS transfer to TLR4/MD2 via LBP and CD14, provide novel insights into the initiation of innate immune responses.

    The challenge for the facial based security system is how to detect facial image falsification such as facial image spoofing. Spoofing occurs when someone try to pretend as a registered user to obtain illegal access and gain advantage from the protected system. This research implements facial image spoofing detection method by analyzing image texture. The proposed method for texture analysis combines the Local Binary Pattern (LBP) and Gray Level Co-occurrence Matrix (GLCM) method. The experimental results show that spoofing detection using LBP and GLCM combination achieves high detection rate compared to that of using only LBP feature or GLCM feature.

    The morbidity of 1557 grandchildren of subjects occupationally exposed to chronic radiation were analyzed. Three groups were singled out. Group 1 consisted of children whose grandfathers were exposed, group 2 of children grandmothers were exposed and group 3 of children whose both grandparent were exposed. Total morbidity level and morbidity structure for 13 classes of diseases and 60 nosological entities was assessed. The study showed that disease incidence in general, structure by disease and individual nosological entities, the share of frequently falling ill children, and health index in the test group corresponded to those in controls. Reliable differences were observed only for respiratory diseases, at the expense of acute respiratory diseases, which were frequent during the second-third years of life in children whose both grandparents were occupationally exposed to radiation [ru

    Patients with chronic renal failure (CRF) may require total joint arthroplasty (TJA) to treat degenerative joint disease, fractures, osteonecrosis, or amyloid arthropathy. There have been conflicting results, however, regarding outcomes of TJA in patients with chronic renal disease. The aim of this case-controlled study was to determine the outcome of TJA in patients with CRF, with particular interest in the incidence of infections and inhospital mortality. We queried our electronic database to determine which patients among the 29,389 TJAs performed at our institution between January 2000 and June 2012 had a diagnosis of CRF. A total of 359 CRF patients were identified and matched for procedure, gender, age (±4 years), date of surgery (±2 years), and body mass index (±5 kg/m 2 ) in a 2:1 ratio to 718 control patients. The incidence of infection and inhospital mortality was not significantly different between the nondialysis CRF patients and controls, whereas it was significantly higher in dialysis-dependent end-stage renal failure patients compared to controls. Of the 50 CRF patients receiving hemodialysis, 10 (20%) developed surgical site infection, of which 4 (8%) were periprosthetic joint infection, and 4 (8%) died during hospital stay. The odds ratio for infection in the dialysis group was 7.54 (95% confidence interval: 2.83-20.12) and 10.46 (95% confidence interval: 1.67-65.34) for the inhospital mortality. We conclude that end-stage renal failure patients receiving hemodialysis have higher postoperative infection and inhospital mortality rates after an elective TJA procedure, whereas nondialysis CRF patients have similar outcomes compared with the general TJA population.

    Full Text Available Introduction: An increased risk for thromboembolism in cancer patients has been observed in patients with solid tumours, whereas little data exist on malignant lymphoma. Aim: Determination of the incidence of TE in patients with non Hodgkin lymphoma (NHL, Hodgkin lymphoma (HL and chronic lymphocytic leukemia (CLL treated in our institution. Material and methods: We reviewed medical records of patients with NHL, HL and CLL diagnosed according to the WHO classification and treated at our institution between January 2006. and December 2014. Results: A total of 1054 patients, 48.4% had high-grade NHL, 20.0% low-grade NHL, 14.5% HL, 7.1% other forms of lymphoma and 10.0% CLL. In group of lymphoma patients, 72 (6.8 % had at least one TE. TE included deep vein thrombosis (38.9%, jugular vein thrombosis (12.5%, pulmonary embolism (11.1%, CNS thrombosis (6.9%, superficial vein thrombosis (2.8%, acute myocardial infarction (1.4% and other (26.4%. In 49 patients thrombosis occurred during treatment or up to three months after therapy completion, whereas in 23 patients thrombosis was diagnosed prior to therapy. Patients with aggressive NHL and CLL had significantly higher incidence of TE (8.63%, 8.57% compared to other types of lymphoma patients (p = 0.009. There is no statistical significance of impact of different types of lymphoproliferative diseases on increased risk for TE. Conclusion: This study confirmed findings of some earlier studies of increased risk of thromboembolic events (TE in patients with aggressive forms of chronic lymphoproliferative diseasses, but there is no significantly impact of gender or age on that risk.

    Full Text Available The aim of this study was to investigate the associations between micronutrient intakes and the 3.6-year incidence of chronic kidney disease (CKD in adults. This cohort study was conducted, within the framework of the Tehran Lipid and Glucose Study, on 1692 subjects, aged ≥30 years, without CKD at the baseline. Dietary intakes were collected using a valid and reliable food-frequency questionnaire. Anthropometrics and biochemical measurements were taken. Chronic kidney disease was defined as eGFR < 60 mL/min/1.73 m2. The mean age of participants was 43.3 ± 11.4 years. In the fully adjusted model, individuals in the top quintile of folate (OR: 0.44, 95% CI: 0.24–0.80, cobalamin (OR: 0.57, 95% CI: 0.34–0.93, vitamin C (OR: 0.38, 95% CI: 0.21–0.69, vitamin E (OR: 0.45, 95% CI: 0.22–0.92, vitamin D (OR: 0.39, 95% CI: 0.21–0.70, potassium (OR: 0.47, 95% CI: 0.23–0.97 and magnesium (OR: 0.41, 95% CI: 0.22–0.76 had decreased risk of CKD, and in the top quintile of sodium (OR: 1.64, 95% CI: 1.03–2.61, subjects had increased risk of CKD, in comparison to the bottom quintile. No significant associations were found between the intakes of other micronutrients. High intake of several micronutrients including vitamins C, E, D, cobalamin, folate, magnesium, and potassium was associated with a decreased risk, while sodium was associated with an increased risk of incident CKD.

    Full Text Available Recognizing patients at a higher risk of developing chronic low back pain (LBP is important in industrial medicine. This study aimed to assess the power and quality of General Health Questionnaire (GHQ for prediction of the odds of chronicity of acute LBP. This study was conducted on industrial workers. All subjects with acute LBP who met the inclusion criteria were enrolled. Demographic characteristics, occupational, physical, and mental parameters and the general health status of subjects were evaluated;  they were followed up for developing chronic LBP for one year. Cigarette smoking, high body mass index, job stress, physical load and high GHQ scores were found to be the risk factors for the progression of acute LBP to chronic LBP (P<0.05. Standing position while working, age, work experience, exercise, level of education, weekly work hours and shift work were not the risk factors for chronic LBP (P>0.05.High GHQ score can be a risk factor for progression of acute LBP to chronic LBP. The GHQ in combination with the Job Content Questionnaire can be used as a quick and simple screening tool for detection of subjects at high risk of chronic LBP when evaluating acute LBP in an occupational setting.

    Chronic subdural hematoma (CSDH) is a rare complication of unruptured aneurysm clipping surgery. The purpose of this study was to identify the incidence and risk factors of postoperative CSDH after surgical clipping for unruptured anterior circulation aneurysms. This retrospective study included 518 patients from a single tertiary institute from January 2008 to December 2013. CSDH was defined as subdural hemorrhage which needed surgical treatment. The degree of brain atrophy was estimated using the bicaudate ratio (BCR) index. We used uni- and multivariate analyses to identify risk factors correlated with CSDH. Sixteen (3.1%) patients experienced postoperative CSDH that required burr hole drainage surgery. In univariate analyses, male gender (p<0.001), size of aneurysm (p=0.030), higher BCR index (p=0.004), and the use of antithrombotic medication (p=0.006) were associated with postoperative CSDH. In multivariate analyses using logistic regression test, male gender [odds ratio (OR) 4.037, range 1.287-12.688], high BCR index (OR 5.376, range 1.170-25.000), and the use of antithrombotic medication (OR 4.854, range 1.658-14.085) were associated with postoperative CSDH (p<0.05). Postoperative subdural fluid collection and arachnoid plasty were not showed statistically significant difference in this study. The incidence of CSDH was 3.1% in unruptured anterior circulation aneurysm surgery. This study shows that male gender, degree of brain atrophy, and the use of antithrombotic medication were associated with postoperative CSDH.

    Chronic rhinosinusitis (CRS) has a broad range of comorbidities. Due to a lack of longitudinal studies, it is not known whether these comorbidities cause CRS, are promoted by CRS, or share a systemic disease process with CRS. The objective of this study was to determine the risk of incident disease within 5 years after a new diagnosis of CRS with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP). We conducted a case-control study nested within the longitudinal cohort of primary care patients in the Geisinger Clinic using electronic health record data. We evaluated incident disease over 5 years in newly diagnosed CRSwNP and CRSsNP cases compared to controls using multivariable Cox regression models. CRSsNP (n = 3612) cases were at greater risk (HR, 95% confidence interval) than controls for incidence of: upper airway diseases, including adenotonsillitis (3.29, 2.41-4.50); lower aerodigestive tract diseases, including asthma (2.69, 2.14-3.38); epithelial conditions, including atopic dermatitis (2.75, 1.23-6.16); and hypertension (1.38, 1.19-1.61). CRSwNP (n = 241) cases were at greater risk for obesity than controls (1.74, 1.08-2.80), but CRSwNP was not associated with other diseases. The risk of other diseases associated with CRS adds to the burden of an already highly burdensome condition, and suggests either that CRS promotes onset of other diseases or is an indicator of systemic disease processes. Different patterns of association with diseases by CRS phenotype may be due to CRSwNP sample size limitations or reflect a different pattern of disease onset by phenotype. These findings have implications for screening guidelines and care of CRS patients. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The majority of patients with chronic myeloid leukemia are successfully managed with life-long treatment with tyrosine kinase inhibitors. In patients in chronic phase, other malignancies are among the most common causes of death, raising concerns on the relationship between these deaths and the off-target effects of tyrosine kinase inhibitors. We analyzed the incidence of second primary malignancies, and related mortality, in 514 chronic myeloid leukemia patients enrolled in clinical trials in which imatinib was given as first-line treatment. We then compared the observed incidence and mortality with those expected in the age- and sex-matched Italian general population, calculating standardized incidence and standardized mortality ratios. After a median follow-up of 74 months, 5.8% patients developed second primary malignancies. The median time from chronic myeloid leukemia to diagnosis of the second primary malignancies was 34 months. We did not find a higher incidence of second primary malignancies compared to that in the age- and sex-matched Italian general population, with standardized incidence ratios of 1.06 (95% CI: 0.57-1.54) and 1.61 (95% CI: 0.92-2.31) in males and females, respectively. Overall, 3.1% patients died of second primary malignancies. The death rate in patients with second primary malignancies was 53% (median overall survival: 18 months). Among females, the observed cancer-related mortality was superior to that expected in the age- and sex-matched Italian population, with a standardized mortality ratio of 2.41 (95% CI: 1.26 - 3.56). In conclusion, our analysis of patients with imatinib-treated chronic myeloid leukemia did not reveal a higher incidence of second primary malignancies; however, the outcome of second primary malignancies in such patients was worse than expected.

    Full Text Available Obesity is a risk factor for chronic kidney disease (CKD and cardiovascular disease. The association between waist to height ratio (WheiR and CKD is unclear. This study evaluated the association between WheiR and CKD.In this longitudinal cohort study, 4841 Japanese workers (3686 males, 1155 females 18 to 67 years of age in 2008 were followed up until 2011. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/1.73 m² (by the Modification of Diet in Renal Disease equation for Japanese or dipstick proteinuria (≥1+. Cox proportional hazards models were used to examine the relationship between WheiR and development of CKD.A total of 384 (7.9% participants (300 men and 84 women were found to have new CKD. The incidence of CKD was 13.7, 24.2, 37.9 and 43.7 per 1000 person-years of follow-up in the lowest, second, third and highest quartiles of WheiR, respectively. After adjustment for potential confounders, the adjusted hazard ratios (95% confidence interval for CKD were 1.00 (reference, 1.23 (0.85, 1.78, 1.59 (1.11, 2.26 and 1.62 (1.13, 2.32 through the quartiles of WheiR, respectively. WheiR had a significant predictive value for the incidence of both proteinuria and low estimated glomerular filtration rate. After subdivision according to gender, the relationship between WheiR and the incidence of CKD was statistically significant in the unadjusted model. However, after adjusting for potential confounders, WheiR was significantly associated with the incidence of CKD in females, whereas it was not significant in males.WheiR, which is commonly used as an index of central obesity, is associated with CKD. There was a significant gender difference in the relationship between CKD and WheiR.

  3. Directed evolution of an LBP/CD14 inhibitory peptide and its anti-endotoxin activity.

    Directory of Open Access Journals (Sweden)

    Li Fang

    Full Text Available BACKGROUND: LPS-binding protein (LBP and its ligand CD14 are located upstream of the signaling pathway for LPS-induced inflammation. Blocking LBP and CD14 binding might prevent LPS-induced inflammation. In previous studies, we obtained a peptide analog (MP12 for the LBP/CD14 binding site and showed that this peptide analog had anti-endotoxin activity. In this study, we used in vitro directed evolution for this peptide analog to improve its in vivo and in vitro anti-endotoxin activity. METHODS: We used error-prone PCR (ep-PCR and induced mutations in the C-terminus of LBP and attached the PCR products to T7 phages to establish a mutant phage display library. The positive clones that competed with LBP for CD14 binding was obtained by screening. We used both in vivo and in vitro experiments to compare the anti-endotoxin activities of a polypeptide designated P1 contained in a positive clone and MP12. RESULTS: 11 positive clones were obtained from among target phages. Sequencing showed that 9 positive clones had a threonine (T to methionine (M mutation in amino acid 287 of LBP. Compared to polypeptide MP12, polypeptide P1 significantly inhibited LPS-induced TNF-α expression and NF-κB activity in U937 cells (P<0.05. Compared to MP12, P1 significantly improved arterial oxygen pressure, an oxygenation index, and lung pathology scores in LPS-induced ARDS rats (P<0.05. CONCLUSION: By in vitro directed evolution of peptide analogs for the LBP/CD14 binding site, we established a new polypeptide (P1 with a threonine (T-to-methionine (M mutation in amino acid 287 of LBP. This polypeptide had high anti-endotoxin activity in vitro and in vivo, which suggested that amino acid 287 in the C-terminus of LBP may play an important role in LBP binding with CD14.

    Background: To compare the risk of type 2 diabetes (T2DM) between patients with and without chronic osteomyelitis (COM), both in humans and in mice, and to explore risk factors in COM patients who developed T2DM. Methods: One hundred seven patients with COM and 114 patients without COM were consecutively enrolled and retrospectively analysed. Clinical data concerning the time to develop diabetes, glucose metabolism, lipid metabolism, inflammatory factors, mental health and frequency of specialist visits were collected. A mouse model of osteomyelitis was used to verify the presence of impaired glucose metabolism and depression. All data were processed by SPSS. Results: The incidence of T2DM was 2.37-fold higher in patients with COM than in those without. In COM patients, subjects with T2DM (DDM) had higher BMI, less exercise and more frequent visits to specialists than those without (Con). Glucose and lipid metabolism were worse in patients with DDM. Patients with DDM had higher levels of white blood cells (12.9±2.1×109/L vs. 11.7±2.2×109/L, p=0.027), CRP (28.4±4.5 mg/L vs. 22.0±4.8 mg/L, pmental illness and lack of exercise were risk factors for the occurrence of T2DM in osteomyelitis. Comprehensive consideration of patient history, including metabolism and mental health, is needed in planning future treatment.

    Low back pain (LBP) is the most common single reason for addressing the health care system due to musculoskeletal pain. More than 80% will experience LBP at some point in life; 6 - 10% of those experiencing LBP will develop persistent and chronic pain with great variance in level of disability...... and pain. Research indicates that LBP is multifactorial and calls for a biopsychosocial model when approaching the patient experiencing LBP. Despite this recognition LBP is poorly understood. A factor for debate has been the contribution of pain-related fear regarding maintenance of chronicity. Recently...

    Background: Coffee intake is associated with reduced risk of liver cancer and chronic liver disease as reported in previous studies, including prospective ones conducted in Asian populations where hepatitis B viruses (HBVs) and hepatitis C viruses (HCVs) are the dominant risk factors. Yet, prospective studies in Western populations with lower HBV and HCV prevalence are sparse. Also, although preparation methods affect coffee constituents, it is unknown whether different methods affect disease associations. Methods: We evaluated the association of coffee intake with incident liver cancer and chronic liver disease mortality in 27 037 Finnish male smokers, aged 50–69, in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, who recorded their coffee consumption and were followed up to 24 years for incident liver cancer or chronic liver disease mortality. Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Results: Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73–0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48–0.63; P-trendcoffee. Conclusion: These findings suggest that drinking coffee may have benefits for the liver, irrespective of whether coffee was boiled or filtered. PMID:23880821

    Nonapnea sleep disorders (NASDs) are associated with an increased risk of stroke, diabetes, and hypertension. No longitudinal study has yet examined the association between NASD and chronic kidney disease (CKD) by using epidemiologic study methods. To test this hypothesis, we examined the effect of NASD on the incidence of CKD in a large population-based retrospective cohort study. Based on a retrospective cohort study of a general population sample of 128 to 436 patients in the Taiwan National Health Insurance Research Database from January 1, 1998 to December 31, 2001, 42 to 812 NASD patients were followed up for 10.2 ± 3.12 years, and additional 85 to 624 individuals had no NASD at baseline. The International Classification of Diseases, Ninth Revision, Clinical Modification was used to identify the diagnosis of disease. Cox proportional hazard regression models were used to assess the association between NASD and subsequent CKD risk. The incidence rate of CKD was significantly higher in the NASD cohort than in the comparison cohort (2.68 vs 1.88 per 1000 person-years, respectively). After we adjusted for age, sex, and comorbidities, the risk of developing CKD was significant for patients with NASD (adjusted hazard ratio [HR] = 1.13; 95% confidence interval [CI] = 1.05-1.22; P types of NASDs, patients with sleep disturbance associated disorders had a 14% increased risk of developing CKD (95% CI = 1.03-1.26; P < 0.01), whereas patients with insomnia had a 13% increased risk of subsequent CKD (95% CI = 1.02-1.25; P < 0.05) compared with the non-NASD cohort. Kaplan-Meier survival analysis indicated that the CKD-free rate was 1% lower in the NASD cohort than in the comparison cohort (log-rank test, P < 0.0001). Our study provides evidence that patients with NASD have an increased risk of developing subsequent CKD compared with patients without NASD; men, elderly people, and patients with concomitant comorbidities are at the greatest

    Acute-on-chronic liver failure (ACLF) is the most life-threatening complication of cirrhosis. Prevalence and outcomes of ACLF have recently been described in hospitalized patients with cirrhosis. However, no data is currently available on the prevalence and the risk factors of ACLF in outpatients with cirrhosis. The aim of this study was to evaluate incidence, predictors and outcomes of ACLF in a large cohort of outpatients with cirrhosis. A total of 466 patients with cirrhosis consecutively evaluated in the outpatient clinic of a tertiary hospital were included and followed up until death and/or liver transplantation for a mean of 45±44months. Data on development of hepatic and extrahepatic organ failures were collected during this period. ACLF was defined and graded according to the EASL-CLIF Consortium definition. During the follow-up, 118 patients (25%) developed ACLF: 57 grade-1, 33 grade-2 and 28 grade-3. The probability of developing ACLF was 14%, 29%, and 41% at 1year, 5years, and 10years, respectively. In the multivariate analysis, baseline mean arterial pressure (hazard ratio [HR] 0.96; p=0.012), ascites (HR 2.53; p=0.019), model of end-stage liver disease score (HR 1.26; p<0.001) and baseline hemoglobin (HR 0.07; p=0.012) were found to be independent predictors of the development of ACLF at one year. As expected, ACLF was associated with a poor prognosis, with a 3-month probability of transplant-free survival of 56%. Outpatients with cirrhosis have a high risk of developing ACLF. The degree of liver failure and circulatory dysfunction are associated with the development of ACLF, as well as low values of hemoglobin. These simple variables may help to identify patients at a high risk of developing ACLF and to plan a program of close surveillance and prevention in these patients. There is a need to identify predictors of acute-on-chronic liver failure (ACLF) in patients with cirrhosis in order to identify patients at high risk of developing ACLF and to

    Predisposing factors in chronic hyperplastic candidosis (CHC) have been poorly recognized. This study aimed at assessing the prevalence of Candida spp. in areas of the oral mucosa showing greater prevalent rate of CHC, such as the retrocomissural area, the lateral borders of the tongue, and the hard-palate mucosa in four groups of individuals presenting predisposing factors as follows: Smoking habits (group I); patients with low salivary flow rate (SFR) (hyposalivation - group II); patients with loss of vertical dimension of occlusion (LVDO -group III); and control subjects (group IV). A total of 44 individuals (age 4090 years, mean: 55.8 years) were divided into four groups: Group I (11 smokers); group II (10 hyposalivation patients); group III (10 LVDO patients); and group IV (control, 13 healthy subjects). All individuals were tested for Candida-pseudohyphae form by direct examination and for Candida spp. culture growth in samples obtained from the retrocomissural, tongue's lateral border, and hard-soft palatal mucosa. Direct examination showed a statistically significant prevalence rate for pseudohyphae (p < 0.05) on the retrocomissural and on tongue's lateral borders of individuals with LVDO. A statistically significant (p < 0.05) culture growth for Candida spp. was found on the retrocomissural areas of those with hyposalivation and with LVDO, and on the palate mucosa and on the tongue's lateral borders in the smokers and in the individuals with LVDO when compared with those of the control group. While direct examination is effective for detecting pseudohyphae, LVDO and tobacco smoking seem to be factors of relevance to the development of CHC. Since CHC has been linked to a high rate of malignant transformation, this study analyzes some clinical (and exogenous) factors that may contribute to the development of CHC and addresses some preventive measures to reduce its incidence.

    Periodontitis is an inflammatory disease caused by subgingival microorganisms and their components, such as lipopolysaccharide (LPS). Responses of the host to LPS are mediated by CD14 and LPS-binding protein (LBP). In this study, it was determined that proteases from a periodontal pathogen, Prevotella intermedia, cleave CD14 and LBP, and thereby modulate the virulence of LPS. Culture supernatants from two strains of P. intermedia (ATCC 25611 and 25261) cleaved CD14 and LBP in a concentration-dependent manner. Zymographic and molecular mass analysis revealed the presence of a membrane-associated, 170-kDa, monomeric protease. Class-specific inhibitors and stimulators demonstrated that this enzyme is a metal-requiring, thiol-activated, cysteine protease. The protease was stable over a wide range of temperatures (4–56 °C) and pH values (4.5–8.5). This enzyme also decreased the expression of interleukin-1β (IL-1β)-specific mRNA in the LPS-activated macrophage-like cell lines U937 and THP-1 in a concentration-dependent manner, indicating that it also cleaves membrane-associated CD14. Furthermore, addition of soluble CD14 abrogated protease-mediated inhibition of IL-1 mRNA expression induced by LPS. The observations suggest that proteolysis of CD14 and LBP by P. intermedia protease might modulate the virulence of LPS at sites of periodontal infections. PMID:12728301

    Full Text Available Lycium barbarum L. polysaccharide (LBP is prepared from Lycium barbarum L. (L. barbarum, which is a traditional Chinese medicine. LPB has been shown to have hypoglycemic effects. In order to gain some mechanistic insights on the hypoglycemic effects of LBP, we investigated the uptake of LBP and its effect on glucose absorption in the human intestinal epithelial cell line Caco2 cell. The uptake of LBP through Caco2 cell monolayer was time-dependent and was inhibited by phloridzin, a competitive inhibitor of SGLT-1. LPB decreased the absorption of glucose in Caco2 cell, and down-regulated the expression of SGLT-1. These results suggest that LBP might be transported across the human intestinal epithelium through SGLT-1 and it inhibits glucose uptake via down-regulating SGLT-1.

    Purpose: The purpose of this study was to evaluate the incidence of chronic knee changes in long-distance runners based on the training status, including distance, running frequency, training pace, and running experience. Methods: MRI of the knee was performed in 26 non-professional runners 5 days after their last training unit. Lesions of the menisci and cartilage (5-point scale), bone marrow and ligaments (3-point scale), and joint effusion were evaluated. A total score comprising all knee lesions in each runner was evaluated. The incidence of the knee changes was correlated with the training level, gender, and age of the runners. Results: Grade 1 lesions of the menisci were found in six runners with a high training level, and in only four runners with a low training level. Grade 1 cartilage lesions were found in three high-trained runners and in one low-trained runner, and grade 2 lesions were found in one high-trained runner and in two low-trained runners, respectively. Grade 1 anterior cruciate ligament lesions were seen in three runners with a high- and in two runners with a low-training level. Runners with a higher training level showed a statistically significant higher score for all chronic knee lesions than those with a lower training level (p < 0.05). Conclusions: MRI findings indicate that a higher training level in long-distance runners is a risk factor for chronic knee lesions

    In order to solve the problem of low recognition rate of traditional feature extraction operators under low-resolution images, a novel algorithm of expression recognition is proposed, named central oblique average center-symmetric local binary pattern (CS-LBP) with adaptive threshold (ATCS-LBP). Firstly, the features of face images can be extracted by the proposed operator after pretreatment. Secondly, the obtained feature image is divided into blocks. Thirdly, the histogram of each block is computed independently and all histograms can be connected serially to create a final feature vector. Finally, expression classification is achieved by using support vector machine (SVM) classifier. Experimental results on Japanese female facial expression (JAFFE) database show that the proposed algorithm can achieve a recognition rate of 81.9% when the resolution is as low as 16×16, which is much better than that of the traditional feature extraction operators.

    Full Text Available The growing demand in the field of security led to the development of interesting approaches in face classification. These works are interested since their beginning in extracting the invariant features of the face to build a single model easily identifiable by classification algorithms. Our goal in this article is to develop more efficient practical methods for face detection. We present a new fast and accurate approach based on local binary patterns (LBP for the extraction of the features that is combined with the new classifier Neighboring Support Vector Classifier (NSVC for classification. The experimental results on different natural images show that the proposed method can get very good results at a very short detection time. The best precision obtained by LBP-NSVC exceeds 99%.

    Full Text Available Low back pain (LBP is a condition which affects most of the individuals at some point of time in their lives. The reportedprevalence of LBP in Indian population is highly variable, and ranges from 6.2% to 92%. The etiology of LBPcovers a vast number of factors including mechanical, psychogenic, degenerative, post traumatic and inflammatory causes. Meticulous history taking andphysical examination are of utmost importance while dealing with a case of LBR Various classes of medicines are available with promising results for control of LBR Non Steroidal Anti Inflammatory Drugs, selective COX2 inhibitors, muscle relaxants, opioid analgesics, tricyclic antidepressants, gabapentin, pregabalin etc. Non pharmacological intervention like spinal manipulation and acupuncture are of controversial effectiveness. Yoga and physiotherapy have evidence supporting their role in improving the pain. Strong need is there to improvise the conventional method of managing LBR Approximately 95% cases of LBP are of non speciJic mechanical wherein diagnostic imaging tests (including X-rays, CT and MRT are not routinely indicated for acute non-specifi LBR Investigations should be limited for the small minority (<2-5% where the cause of back pain is suspected to be either inflammatory (ie. systemic autoimmune diseases viz. ankylosing spondylitis or spondyloarthritis or sinister. Active rehabilitation should be encouraged and the patients should not be prescribed bed rest as a treatntenf Management of LBPrequires an umbrella approach which, apart from pharmacological intervention, screening for psychosocial prognostic indicators in LBP may ultimately guide treatment protocols in physical therapy for more comprehensive patient care along with patient empowerment in terms of health education, participation in decision muking and responsibility of taking good self-care.

    Full Text Available Resistance to pathogens is important for the sustainability and profitability of food fish production. In immune-related genes, the lipopolysaccharide-binding protein (LBP gene is an important mediator of the inflammatory reaction. We analyzed the cDNA and genomic structure of the LBP gene in tilapia. The full-length cDNA (1901 bp of the gene contained a 1416 bp open reading frame, encoding 471 amino acid residues. Its genomic sequence was 5577 bp, comprising 15 exons and 14 introns. Under normal conditions, the gene was constitutively expressed in all examined tissues. The highest expression was detected in intestine and kidney. We examined the responses of the gene to challenges with two bacterial pathogens Streptcoccus agalactiae and Aeromonas hydrophila. The gene was significantly upregulated in kidney and spleen post-infection with S. agalactiae and A. hydrophila, respectively. However, the expression profiles of the gene after the challenge with the two pathogens were different. Furthermore, we identified three SNPs in the gene. There were significant associations (p < 0.05 of two of the three SNPs with the resistance to A. hydrophila, but not with the resistance to S. agalactiae or growth performance. These results suggest that the LBP gene is involved in the acute-phase immunologic response to the bacterial infections, and the responses to the two bacterial pathogens are different. The two SNPs associated with the resistance to A. hydrophila may be useful in the selection of tilapia resistant to A. hydrophila.

    Acute kidney injury (AKI) is a serious complication among hospitalized individuals and is closely associated with chronic kidney disease (CKD). This retrospective cohort study evaluated the incidences of AKI according to CKD stage at Kochi Medical School hospital during 1981-2011. AKI was defined and staged according to the kidney disease improving global outcomes criteria, using serum creatinine levels. We analyzed data from 122,653 Japanese patients (57,105 men, 46.6 %). The incidence of AKI was 7.8 % (95 % confidence interval 7.7-8.0 %). Compared to non-AKI patients, patients with stage 1-2 AKI were more likely to be men. Patients with stage 1-2 AKI were significantly older than non-AKI or stage 3 AKI patients. The incidences of AKI were 6.7, 5.9, 10.4, 18.4, 30.0, and 48.8 % among individuals with estimated glomerular filtration rates of ≥90, 60-89, 45-59, 30-44, 15-29, and kidney function, and the proportions among outpatients exhibited step-wise increases with milder pre-existing reduced kidney function. CKD was a risk factor for AKI, and the incidence of AKI was positively associated with pre-existing reduced kidney function (CKD stage). We also found that the prevalence of AKI at early-stage CKD among outpatients was higher than expected. We suggest that outpatients should be monitored for AKI, given its unexpected incidence in that population.

    To determine if chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (HSCT) is associated with stable or progressive dry eye disease and to determine the true incidence in patients with no prior history of dry eye disease. A nonconcurrent cohort study at a single institution with 136 patients who had no previous history of dry eye disease before HSCT. Survival analysis was used to estimate dry eye disease incidence. The incidence rate was calculated using life tables as the number of observed dry eye disease cases divided by the person-time at risk accumulated by the cohort. Transition probabilities were calculated from time of transplant to time of diagnosis, and then to last recorded visit. Incidence rate was 0.8 cases of dry eye disease per person-year, and half of the population at risk developed dry eye disease during the first 10 months post transplant. Time to develop dry eye disease was 2.5 months for mild dry eye disease, 9.6 months for moderate dry eye disease, and 13.2 months for severe dry eye disease. In terms of cumulative incidence, 73% of subjects developed dry eye disease (50% mild, 16% moderate, and 7% severe) at the time of diagnosis. Our findings suggest that dry eye disease associated with cGVHD is an extremely frequent event and shows a wide spectrum of severity, with a mild form presenting early and a moderate to severe form presenting later after HSCT. These findings need to be studied further to elucidate if these are two different pathophysiological entities or just different expressions of the same pathology.

    We report a population-based study conducted in Iceland to determine the incidence, clinical characteristics and prognosis of idiopathic chronic inflammatory demyelinating polyneuropathy (CIDP) during a 21-year period. Cases were identified from the records of all practicing neurologists in the country, the only neurology department in the country and both neurophysiology laboratories. All index cases met the 2010 European Federation of Neurological Societies/Peripheral Nerve Society criteria for CIDP. Nineteen individuals fulfilled the diagnostic criteria during the study period. The average annual incidence was 0.3/100,000 (95% CI 0.04-2.47). There were 14 men (74%) in a gender ratio of 1:2.8. The mean age at diagnosis was 57 (range 19-81 years): women, 36 years and men, 63 years; p = 0.0006. The disease course was remitting-relapsing in 21% and chronic progressive or monophasic in 79%. The average length of follow-up was 6.9 years. The standardized mortality ratio for the 21-year study period was 0.9 (95% CI 0.3-2.2). We believe we have identified all diagnosed with CIDP in Iceland during a 21-year period. Many had no or only limited disease progression over the years and mortality is not increased compared with the general population. © 2016 S. Karger AG, Basel.

  7. Incident Pneumonia and Mortality in Patients with Chronic Obstructive Pulmonary Disease. A Double Effect of Inhaled Corticosteroids?

    Science.gov (United States)

    Scanlon, Paul D.

    2015-01-01

    Inhaled corticosteroids are commonly prescribed for patients with severe chronic obstructive pulmonary disease. Although their use improves quality of life and reduces exacerbations, it is associated with increased risk of pneumonia. Curiously, their use has not been associated with increased risk of pneumonia-related or overall mortality. We review pertinent literature to further explore the effects of inhaled corticosteroids on incident pneumonia and mortality in patients with chronic obstructive pulmonary disease. The association of use of inhaled corticosteroids and incident pneumonia is substantial and has been present in the majority of the studies on the topic. This includes both randomized controlled trials and observational studies. However, all of the studies have substantial risk of bias. Most randomized trials are limited by lack of systematic ascertainment of pneumonia; they depended on adverse event reporting. Many observational studies included proper radiographic assessment of pneumonia, but they are limited by their retrospective, observational design. The unadjusted higher risk of pneumonia is associated with longer duration of use, more potent ICS compounds, and higher doses. That implies a dose–effect relationship. Unlike pneumonia, mortality is a precise outcome. Despite the robust association of inhaled corticosteroid use with increased risk of pneumonia, all studies find either no difference or a reduction in pulmonary-related and overall mortality associated with the use of inhaled corticosteroids. These observations suggest a double effect of inhaled corticosteroids (i.e., an adverse effect plus an unexplained mitigating effect). PMID:25409118

  9. Effective physical treatment for chronic low back pain.

    Science.gov (United States)

    Maher, C G

    2004-01-01

    It is now feasible to adopt an evidence-based approach when providing physical treatment for patients with chronic LBP. A summary of the efficacy of a range of physical treatments is provided in Table 1. The evidence-based primary care options are exercise, laser, massage, and spinal manipulation; however, the latter three have small or transient effects that limit their value as therapies for chronic LBP. In contrast, exercise produces large reductions in pain and disability, a feature that suggests that exercise should play a major role in the management of chronic LBP. Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered. Outside of primary care, multidisciplinary treatment or functional restoration is effective; however, the high cost probably means that these programs should be reserved for patients who do not respond to cheaper treatment options for chronic LBP. Although there are now effective treatment options for chronic LBP, it needs to be acknowledged that the problem of chronic LBP is far from solved. Though treatments can provide marked improvements in the patient's condition, the available evidence suggests that the typical chronic LBP patient is left with some residual pain and disability. Developing new, more powerful treatments and refining the current group of known effective treatments is the challenge for the future.

    We aimed at determining peptic ulcer disease (PUD) incidence among chronic kidney disease (CKD) patients during 1998-2008, compared to patients without CKD, and at examining associations between CKD and PUD. Data for 1998-2008 were extracted from the National Health Insurance Research Database in Taiwan. The annual PUD incidence (cases per thousand persons per year) was calculated separately for patients with and without CKD. Characteristics of patients with newly diagnosed PUD (n = 16322) were compared to those of a control group without PUD (n = 32644). The 2 groups were matched for age, sex, and index year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Over the 10-year period, the PUD incidence was ∼10-12 times higher in CKD patients than in those without CKD. Its incidence in elderly CKD patients increased rapidly over time. For CKD patients, most PUD events (>95%) were managed during hospitalization. Peptic ulcer risk, adjusted for all potential confounders, was much higher in CKD patients undergoing hemodialysis (adjusted OR, 9.74; 95% CI, 7.11-13.31). Maintenance hemodialysis patients were 2 times more likely to have gastric ulcers than duodenal ulcers, while CKD patients not on dialysis had similar risks for both. There were no significant interactions between medications and CKD status on the peptic ulcer risk. Unlike CKD patients on nonsteroidal anti-inflammatory drugs and clopidogrel, those on aspirin did not have a higher peptic ulcer risk (adjusted OR, 0.88; 95% CI, 0.44-1.77). CKD patients have a substantially increased PUD risk, and the majority of CKD patients with PUD require hospital management. Further, peptic ulcer risk is affected by hemodialysis therapy, patient status (inpatient vs. outpatient), and ulcerogenic medications.

    Histological images have characteristics, such as texture, shape, colour and spatial structure, that permit the differentiation of each fundamental tissue and organ. Texture is one of the most discriminative features. The automatic classification of tissues and organs based on histology images is an open problem, due to the lack of automatic solutions when treating tissues without pathologies. In this paper, we demonstrate that it is possible to automatically classify cardiovascular tissues using texture information and Support Vector Machines (SVM). Additionally, we realised that it is feasible to recognise several cardiovascular organs following the same process. The texture of histological images was described using Local Binary Patterns (LBP), LBP Rotation Invariant (LBPri), Haralick features and different concatenations between them, representing in this way its content. Using a SVM with linear kernel, we selected the more appropriate descriptor that, for this problem, was a concatenation of LBP and LBPri. Due to the small number of the images available, we could not follow an approach based on deep learning, but we selected the classifier who yielded the higher performance by comparing SVM with Random Forest and Linear Discriminant Analysis. Once SVM was selected as the classifier with a higher area under the curve that represents both higher recall and precision, we tuned it evaluating different kernels, finding that a linear SVM allowed us to accurately separate four classes of tissues: (i) cardiac muscle of the heart, (ii) smooth muscle of the muscular artery, (iii) loose connective tissue, and (iv) smooth muscle of the large vein and the elastic artery. The experimental validation was conducted using 3000 blocks of 100 × 100 sized pixels, with 600 blocks per class and the classification was assessed using a 10-fold cross-validation. using LBP as the descriptor, concatenated with LBPri and a SVM with linear kernel, the main four classes of tissues were

    The marine environment represents a relatively untapped source of functional ingredients that can be applied to various aspects of food processing, storage, and fortification. Moreover, numerous marine-based compounds have been identified as having diverse biological activities, with some reported to interfere with the pathogenesis of diseases. Bioactive peptides isolated from fish protein hydrolysates as well as algal fucans, galactans and alginates have been shown to possess anticoagulant, anticancer and hypocholesterolemic activities. Additionally, fish oils and marine bacteria are excellent sources of omega-3 fatty acids, while crustaceans and seaweeds contain powerful antioxidants such as carotenoids and phenolic compounds. On the basis of their bioactive properties, this review focuses on the potential use of marine-derived compounds as functional food ingredients for health maintenance and the prevention of chronic diseases.

    Hyperspectral imaging, recording intrinsic spectral information of the skin cross different spectral bands, become an important issue for robust face recognition. However, the main challenges for hyperspectral face recognition are high data dimensionality, low signal to noise ratio and inter band misalignment. In this paper, hyperspectral face recognition based on LBP (Local binary pattern) and SWLD (Simplified Weber local descriptor) is proposed to extract discriminative local features from spatio-spectral fusion information. Firstly, the spatio-spectral fusion strategy based on statistical information is used to attain discriminative features of hyperspectral face images. Secondly, LBP is applied to extract the orientation of the fusion face edges. Thirdly, SWLD is proposed to encode the intensity information in hyperspectral images. Finally, we adopt a symmetric Kullback-Leibler distance to compute the encoded face images. The hyperspectral face recognition is tested on Hong Kong Polytechnic University Hyperspectral Face database (PolyUHSFD). Experimental results show that the proposed method has higher recognition rate (92.8%) than the state of the art hyperspectral face recognition algorithms.

  18. Perceptual Image Hashing Using Latent Low-Rank Representation and Uniform LBP

    2018-02-01

    Full Text Available Robustness and discriminability are the two most important features of perceptual image hashing (PIH schemes. In order to achieve a good balance between perceptual robustness and discriminability, a novel PIH algorithm is proposed by combining latent low-rank representation (LLRR and rotation invariant uniform local binary patterns (RiuLBP. LLRR is first applied on resized original images to the principal feature matrix and to the salient feature matrix, since it can automatically extract salient features from corrupted images. Following this, Riulocal bin features are extracted from each non-overlapping block of the principal feature matrix and of the salient feature matrix, respectively. All features are concatenated and scrambled to generate final binary hash code. Experimental results show that the proposed hashing algorithm is robust against many types of distortions and attacks, such as noise addition, low-pass filtering, rotation, scaling, and JPEG compression. It outperforms other local binary patterns (LBP based image hashing schemes in terms of perceptual robustness and discriminability.

    Resistance to pathogens is important for the sustainability and profitability of food fish production. In immune-related genes, the lipopolysaccharide-binding protein (LBP) gene is an important mediator of the inflammatory reaction. We analyzed the cDNA and genomic structure of the LBP gene in tilapia. The full-length cDNA (1901 bp) of the gene contained a 1416 bp open reading frame, encoding 471 amino acid residues. Its genomic sequence was 5577 bp, comprising 15 exons and 14 introns. Under normal conditions, the gene was constitutively expressed in all examined tissues. The highest expression was detected in intestine and kidney. We examined the responses of the gene to challenges with two bacterial pathogens Streptcoccus agalactiae and Aeromonas hydrophila. The gene was significantly upregulated in kidney and spleen post-infection with S. agalactiae and A. hydrophila, respectively. However, the expression profiles of the gene after the challenge with the two pathogens were different. Furthermore, we identified three SNPs in the gene. There were significant associations (p tilapia resistant to A. hydrophila. PMID:25470022

    Discussion:. Our findings might indicate a maladaptive psychobiological interaction in chronic LBP patients characterized by a disrupted amygdala-PAG-FC that is modulated by the degree of pain-related fear. These results shed new light on brain mechanisms underlying psychological factors that may have pronociceptive effects in chronic LBP.

    Although the relationship between low back pain (LBP) and the size of certain trunk muscles has been extensively studied, the relationship between gluteus maximus (GM) size and LBP has been only minimally examined. Determining whether such a relationship exists would help improve our understanding of the etiology of LBP, and possibly provide a rationale for the use of therapeutic exercise interventions targeting GM with LBP patients. The objective of this study was to compare gluteus maximus cross-sectional area in individuals with chronic LBP, and in a group of individuals without LBP. Our hypothesis was that individuals with LBP would have greater atrophy in their gluteus maximus muscles than our control group. For this case-control study, we analyzed medical history and pelvic computed tomography (CT) scans for 36 female patients with a history of chronic LBP, and 32 female patients without a history of LBP. Muscle cross-sectional area of gluteus maximus was measured from axial CT scans using OsiriX MD software, then was normalized to patient height, and used to compare the two groups. The number of back pain-related medical visits was also correlated with gluteus maximus cross-sectional area. Mean normalized cross-sectional area was significantly smaller in the LBP group than in the control group, with t = 2.439 and P<0.05. The number of back pain-related visits was found to be significantly correlated with normalized cross-sectional area, with r = -0.270 and P<0.05. The atrophy seen in the present research may reflect incidental disuse atrophy seen with LBP, which is present in many muscle groups after prolonged immobilization or with a sedentary lifestyle. This research demonstrated a previously only minimally explored relationship between gluteus maximus cross-sectional area and LBP in women. Further research is indicated in individuals with varying age, sex, and LBP diagnoses.

    Dietary protein restriction is recommended for patients with moderate to severe renal insufficiency. Long-term data on the relationship between dietary protein sources and risk for incident kidney disease in individuals with normal kidney function are largely missing. This study aimed to assess the association between dietary protein sources and incident chronic kidney disease (CKD). Prospective cohort. Atherosclerosis Risk in Communities study participants from 4 US communities. A total of 11,952 adults aged 44-66 years in 1987-1989 who were free of diabetes mellitus, cardiovascular disease, and had an estimated glomerular filtration rate (eGFR) ≥ 60 mL/minute/1.73 m 2 . A 66-item food frequency questionnaire was used to assess food intake. CKD stage 3 was defined as a decrease in eGFR of ≥25% from baseline resulting in an eGFR of less than 60 mL/minute/1.73 m 2 ; CKD-related hospitalization; CKD-related death; or end-stage renal disease. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression. During a median follow-up of 23 years, there were 2,632 incident CKD cases. Red and processed meat consumption was associated with increased CKD risk (HR Q5 vs. Q1 : 1.23, 95% CI: 1.06-1.42, p trend  = 0.01). In contrast, higher dietary intake of nuts, legumes, and low-fat dairy products was associated with lower CKD risk (nuts: HR Q5 vs. Q1 : 0.81, 95% CI: 0.72-0.92, p trend protein sources with risk of incident CKD; with red and processed meat being adversely associated with CKD risk; and nuts, low-fat dairy products, and legumes being protective against the development of CKD.

    Full Text Available Background This is a study of the epidemiology of acute and chronic episodes of care (EoCs in the Transition Project in three countries. We studied the duration of EoCs for acute and chronic health problems and the relationship of incidence to prevalence rates for these EoCs.Method The Transition Project databases collect data on all elements of the doctor–patient encounter in family medicine. Family doctors code these elements using the International Classification of Primary Care.We used the data from three practice populations to study the duration of EoCs and the ratio of incidence to prevalence for common health problems.Results We found that chronic health problems tended to have proportionately longer duration EoCs, as expected, but also a lower incidence to prevalence rate ratio than acute health problems. Thus, the incidence to prevalence index could be used to define a chronic condition as one with a low ratio, below a defined threshold.Conclusions Chronic health problems tend to have longer duration EoCs, proportionately, across populations. This result is expected, but we found important similarities and differences which make defining a problem as chronic on the basis of time rather difficult. The ratio of incidence to prevalence rates has potential to categorise health problems into acute or chronic categories, at different ratio thresholds (such as 20, 30 or 50%. It seems to perform well in this study of three family practice populations, and is proposed to the scientific community for further evaluation.

  5. Ir-LBP, an ixodes ricinus tick salivary LTB4-binding lipocalin, interferes with host neutrophil function.

    Directory of Open Access Journals (Sweden)

    Jérôme Beaufays

    Full Text Available BACKGROUND: During their blood meal, ticks secrete a wide variety of proteins that can interfere with their host's defense mechanisms. Among these proteins, lipocalins play a major role in the modulation of the inflammatory response. METHODOLOGY/PRINCIPAL FINDINGS: We previously identified 14 new lipocalin genes in the tick Ixodes ricinus. One of them codes for a protein that specifically binds leukotriene B4 with a very high affinity (Kd: +/-1 nM, similar to that of the neutrophil transmembrane receptor BLT1. By in silico approaches, we modeled the 3D structure of the protein and the binding of LTB4 into the ligand pocket. This protein, called Ir-LBP, inhibits neutrophil chemotaxis in vitro and delays LTB4-induced apoptosis. Ir-LBP also inhibits the host inflammatory response in vivo by decreasing the number and activation of neutrophils located at the tick bite site. Thus, Ir-LBP participates in the tick's ability to interfere with proper neutrophil function in inflammation. CONCLUSIONS/SIGNIFICANCE: These elements suggest that Ir-LBP is a "scavenger" of LTB4, which, in combination with other factors, such as histamine-binding proteins or proteins inhibiting the classical or alternative complement pathways, permits the tick to properly manage its blood meal. Moreover, with regard to its properties, Ir-LBP could possibly be used as a therapeutic tool for illnesses associated with an increased LTB4 production.

    Full Text Available We conducted a National Health Insurance Research Database-based Taiwanese nationwide population-based cohort study to evaluate whether Chinese herbal medicine (CHM treatment decreased the incidence of chronic hepatitis in breast cancer patients receiving chemotherapy and/or radiotherapy. A total of 81171 patients were diagnosed with breast cancer within the defined study period. After randomly equal matching, data from 13856 patients were analyzed. Hazard ratios of incidence rate of chronic hepatitis were used to determine the influence and therapeutic potential of CHM in patients with breast cancer. The patients with breast cancer receiving CHM treatment exhibited a significantly decreased incidence rate of chronic hepatitis even across the stratification of age, CCI score, and treatments. The cumulative incidence of chronic hepatitis for a period of seven years after initial breast cancer diagnosis was also reduced in the patients receiving CHM treatment. The ten most commonly used single herbs and formulas were effective in protecting liver function in patients with breast cancer, where Hedyotis diffusa and Jia-Wei-Xiao-Yao-San were the most commonly used herbal agents. In conclusion, our study provided information that western medicine therapy combined with CHM as an adjuvant modality may have a significant impact on liver protection in patients with breast cancer.

    The risk of tuberculosis (TB) is significantly increased in chronic kidney disease (CKD). Data on TB in CKD in the UK are sparse; most information stems from countries with high background prevalence. The aim of this study was to estimate the incidence of TB in CKD patients in South East London and to describe the epidemiology, treatment, and outcome. CKD patients with TB between 1994 and 2010 were identified retrospectively. Data were collected on type of renal replacement therapy, the method of TB diagnosis, disease site, treatment regimens, and risk factors. Forty patients were identified of whom 67.5% had CKD stages IV-V. Sixty-five percent were from non-UK born ethnic minorities. Median time from diagnosis of CKD to TB development was 12 months (range 0-192 months). Cumulative incidence of TB was 1267/100,000 [95% confidence interval (CI): 630-1904; 85 × background UK rate] in hemodialysis patients; 398/100,000 (95% CI: 80-1160; 26 × background UK rate) in peritoneal dialysis; and 522/100,000 (CI: 137-909; 35 × background UK rate) in transplant recipients. Sixty-three percent of patients had pulmonary TB and 25% of patients with culture-positive TB had resistant isolates. Fifty percent of patients were immunosuppressed due to drugs, diabetes, and/or retroviral disease. Treatment regimens were according to recent national guidance in 73% of cases. Seventy-six percent of patients experienced side effects. Greater awareness of risk factors, drug resistance, treatment regimens, and potential side effects is needed.

    Although the connective tissues forming the fascial planes of the back have been hypothesized to play a role in the pathogenesis of chronic low back pain (LBP), there have been no previous studies quantitatively evaluating connective tissue structure in this condition. The goal of this study was to perform an ultrasound-based comparison of perimuscular connective tissue structure in the lumbar region in a group of human subjects with chronic or recurrent LBP for more than 12 months, compared with a group of subjects without LBP. In each of 107 human subjects (60 with LBP and 47 without LBP), parasagittal ultrasound images were acquired bilaterally centered on a point 2 cm lateral to the midpoint of the L2-3 interspinous ligament. The outcome measures based on these images were subcutaneous and perimuscular connective tissue thickness and echogenicity measured by ultrasound. There were no significant differences in age, sex, body mass index (BMI) or activity levels between LBP and No-LBP groups. Perimuscular thickness and echogenicity were not correlated with age but were positively correlated with BMI. The LBP group had approximately 25% greater perimuscular thickness and echogenicity compared with the No-LBP group (ANCOVA adjusted for BMI, p<0.01 and p<0.001 respectively). This is the first report of abnormal connective tissue structure in the lumbar region in a group of subjects with chronic or recurrent LBP. This finding was not attributable to differences in age, sex, BMI or activity level between groups. Possible causes include genetic factors, abnormal movement patterns and chronic inflammation.

    Some evidence suggests that chronic kidney disease is a risk factor for lower-extremity peripheral artery disease. We aimed to quantify the independent and joint associations of two measures of chronic kidney disease (estimated glomerular filtration rate [eGFR] and albuminuria) with the incidence of peripheral artery disease. In this collaborative meta-analysis of international cohorts included in the Chronic Kidney Disease Prognosis Consortium (baseline measurements obtained between 1972 and 2014) with baseline measurements of eGFR and albuminuria, at least 1000 participants (this criterion not applied to cohorts exclusively enrolling patients with chronic kidney disease), and at least 50 peripheral artery disease events, we analysed adult participants without peripheral artery disease at baseline at the individual patient level with Cox proportional hazards models to quantify associations of creatinine-based eGFR, urine albumin-to-creatinine ratio (ACR), and dipstick proteinuria with the incidence of peripheral artery disease (including hospitalisation with a diagnosis of peripheral artery disease, intermittent claudication, leg revascularisation, and leg amputation). We assessed discrimination improvement through c-statistics. We analysed 817 084 individuals without a history of peripheral artery disease at baseline from 21 cohorts. 18 261 cases of peripheral artery disease were recorded during follow-up across cohorts (median follow-up was 7·4 years [IQR 5·7-8·9], range 2·0-15·8 years across cohorts). Both chronic kidney disease measures were independently associated with the incidence of peripheral artery disease.

    Patients who die from stomach cancer are still present. Early diagnosis is crucial in reducing the mortality rate of cancer patients. Therefore, computer aided methods have been developed for early detection in this article. Stomach cancer images were obtained from Fırat University Medical Faculty Pathology Department. The Local Binary Patterns (LBP) and Histogram of Oriented Gradients (HOG) features of these images are calculated. At the same time, Sammon mapping, Stochastic Neighbor Embedding (SNE), Isomap, Classical multidimensional scaling (MDS), Local Linear Embedding (LLE), Linear Discriminant Analysis (LDA), t-Distributed Stochastic Neighbor Embedding (t-SNE), and Laplacian Eigenmaps methods are used for dimensional the reduction of the features. The high dimension of these features has been reduced to lower dimensions using dimensional reduction methods. Artificial neural networks (ANN) and Random Forest (RF) classifiers were used to classify stomach cancer images with these new lower feature sizes. New medical systems have developed to measure the effects of these dimensions by obtaining features in different dimensional with dimensional reduction methods. When all the methods developed are compared, it has been found that the best accuracy results are obtained with LBP_MDS_ANN and LBP_LLE_ANN methods.

    Chronic renal failure is a global public health problem. In developed countries, this disease occurs mainly in the elderly, but in Africa it rather affects active young subjects. This disease need for expensive treatments in a low income country, because of its costs. Our aim is to describe the epidemiology of new cases of chronic renal failure in Madagascar. This is a retrospective, descriptive study of 239 patients with chronic renal failure over a 3 year period, starting from 1 January 2007 to 31 December 2009, in the Department of Internal Medicine and Nephrology at University Hospital of Antananarivo. The incidence was 8.51% among patients hospitalized in the Department. The average age of patients was 45.4 years with extremes of 16 and 82 years and a sex ratio 1,46. The main antecedent was arterial hypertension (59.8%). Chronic renal failure was terminal in 75.31% of the cases (n=180). The causes of chronic renal failure were dominated by chronic glomerulonephritis (40.1%), nephroangiosclerosis (35.5%). Hemodialysis was performed in 3 patients (1.26%), no patient was scheduled for a renal transplantation. Mortality rate in the Department was 28.87%. Chronic renal failure is a debilitating disease with a dreadful prognosis which affects young patients in Madagascar. Its treatment remains inaccessible to the majority of patients. The focus must be mainly on prevention, especially on early effective management of infections, arterial hypertension and diabetes to reduce its negative impacts on the community and public health. The project on renal transplantation: living donor, effective and less expensive treatment compared to hemodialysis could also be a good solution for these Malagasy young subjects.

    Serum uric acid has shown to be a predictor of renal disease progression in most but not all studies. This study aims to test whether renal function-normalized serum uric acid is superior to serum uric acid as the predictor of incident chronic kidney disease in type 2 diabetes mellitus patients. In this study, 1339 type 2 diabetes mellitus patients with estimated glomerular filtration rate ⩾60 mL/min/1.73 m 2 and normouricemia were included. Renal function-normalized serum uric acid was calculated using serum uric acid/creatinine. Cox regression analysis was used to estimate the association between serum uric acid, renal function-normalized serum uric acid and incident chronic kidney disease. In total, 74 (5.53%) patients developed to chronic kidney disease 3 or greater during a median follow-up of 4 years, with older ages, longer diabetes duration and lower estimated glomerular filtration rate at baseline. The decline rate of estimated glomerular filtration rate was positively correlated with serum uric acid/creatinine ( r = 0.219, p type 2 diabetes mellitus patients.

    Objective Trends in recorded diagnoses of chronic fatigue syndrome (CFS, also known as 'myalgic encephalomyelitis' (ME)) and fibromyalgia (FM) in the UK were last reported more than ten years ago, for the period 1990-2001. Our aim was to analyse trends in incident diagnoses of CFS/ME and FM for the period 2001-2013, and to investigate whether incidence might vary by index of multiple deprivation (IMD) score. Design Electronic health records cohort study. Setting NHS primary care practices in the UK. Participants Participants: Patients registered with general practices linked to the Clinical Practice Research Datalink (CPRD) primary care database from January 2001 to December 2013. Main outcome measure Incidence of CFS/ME, FM, post-viral fatigue syndrome (PVFS), and asthenia/debility. Results The overall annual incidence of recorded cases of CFS/ME was 14.8 (95% CI 14.5, 15.1) per 100,000 people. Overall annual incidence per 100,000 people for FM was 33.3 (32.8-33.8), for PVFS 12.2 (11.9, 12.5), and for asthenia/debility 7.0 (6.8, 7.2). Annual incidence rates for CFS/ME diagnoses decreased from 17.5 (16.1, 18.9) in 2001 to 12.6 (11.5, 13.8) in 2013 (annual percent change -2.8% (-3.6%, -2.0%)). Annual incidence rates for FM diagnoses decreased from 32.3 (30.4, 34.3) to 27.1 (25.5, 28.6) in 2007, then increased to 38.2 (36.3, 40.1) per 100,000 people in 2013. Overall annual incidence of recorded fatigue symptoms was 2246 (2242, 2250) per 100,000 people. Compared with the least deprived IMD quintile, incidence of CFS/ME in the most deprived quintile was 39% lower (incidence rate ratio (IRR) 0.61 (0.50, 0.75)), whereas rates of FM were 40% higher (IRR 1.40 (0.95, 2.06)). Conclusion These analyses suggest a gradual decline in recorded diagnoses of CFS/ME since 2001, and an increase in diagnoses of fibromyalgia, with opposing socioeconomic patterns of lower rates of CFS/ME diagnoses in the poorest areas compared with higher rates of FM diagnoses.

    The objective of this study was to assess the association between severe disc degeneration (DD) and low back pain (LBP). A case-control study was conducted with 304 subjects, aged 35-50, recruited in routine clinical practice across six hospitals; 240 cases (chronic LBP patients with a median pain duration of 46 months) and 64 controls (asymptomatic subjects without any lifetime history of significant LBP). The following variables were assessed once, using previously validated methods: gender, age, body mass index (BMI), lifetime smoking exposure, degree of physical activity, severity of LBP, disability, and findings on magnetic resonance (MRI) (disc degeneration, Modic changes (MC), disc protrusion/hernia, annular tears, spinal stenosis, and spondylolisthesis). Radiologists who interpreted MRI were blinded to the subjects' characteristics. A multivariate logistic regression model assessed the association between severe DD and chronic LBP, adjusting for gender, age, BMI, physical activity, MC, disc protrusion/hernia, and spinal stenosis. Severe DD at ≥1 level was found in 46.9 % of the controls and 65.8 % of the cases. Crude odds ratio (95 % CI), for suffering chronic LBP when having severe DD, was 2.06 (1.05; 4.06). After adjusting for ''MC'' and ''disc protrusion/hernia,'' it was 1.81 (0.81; 4.05). The association between severe DD and LBP ceases to be significant when adjusted for MC and disc protrusion/hernia. These results do not support that DD as a major cause of chronic LBP. (orig.)

    People with chronic kidney disease (CKD) have an increased prevalence of depression, anxiety, and neuropathic pain. We examined prevalence, incidence, indication for, and choice of antidepressants among patients with and without CKD. Using the UK Clinical Practice Research Datalink, we identified patients with CKD (two measurements of estimated glomerular filtration rate antidepressant prescribing in the six months prior to index date (prevalence), the first prescription after index date among non-prevalent users (incidence), and recorded diagnoses (indication). We compared antidepressant choice between patients with and without CKD among patients with a diagnosis of depression. There were 242 349 matched patients (median age 76 [interquartile range 70-82], male 39.3%) with and without CKD. Prevalence of antidepressant prescribing was 16.3 and 11.9%, and incidence was 57.2 and 42.4/1000 person-years, in patients with and without CKD, respectively. After adjusting for confounders, CKD remained associated with higher prevalence and incidence of antidepressant prescription. Regardless of CKD status, selective serotonin reuptake inhibitors were predominantly prescribed for depression or anxiety, while tricyclic antidepressants were prescribed for neuropathic pain or other reasons. Antidepressant choice was similar in depressed patients with and without CKD. The rate of antidepressant prescribing was nearly one and a half times higher among people with CKD than in the general population. © 2017 The Authors.

    We aimed to investigate the association of dietary total antioxidant capacity (TAC) with incidence of CKD in subjects with dysglycemia. We followed-up 1179 subjects aged ≥30 years with dysglycemia from the Tehran Lipid and Glucose Study (TLGS) for 3 years, who were initially free of CKD. Dietary intakes of TAC, vitamin C, vitamin E, and β-carotene were assessed by a food-frequency questionnaire at the baseline. Dietary TAC was estimated using the oxygen radical absorbance capacity method. Estimated glomerular filtration rate (eGFR) was calculated, using the Modification of Diet in Renal Disease Study equation and CKD was defined as eGFR intake, the top tertile of dietary TAC compared to the bottom was associated with 39% [95% confidence interval (CI) = 0.40-0.93] lower risk of incident CKD (P for trend = 0.025). Furthermore, the highest tertile of vitamin C intake compared to the lowest risk of incident CKD was decreased (OR 0.60; 95% CI 0.38-0.93, P trend 0.023). Intakes of vitamin E and β-carotene were not significantly associated with incident CKD risk. Our findings suggest that diets high in TAC are associated with a lower risk of incident CKD among subjects with hyperglycemia after 3 years of follow-up.

    Clinical observation suggests that hip abductor weakness is common in patients with low back pain (LBP). The purpose of this study is to describe and compare the prevalence of hip abductor weakness in a clinical population with chronic non-specific LBP and a matched sample without LBP. One hundred fifty subjects with chronic non-specific LBP and a matched cohort of 75 control subjects were recruited. A standardized back and hip physical exam was performed. Specifically tensor fascia lata, gluteus medius, and gluteus maximus strength were assessed with manual muscle testing. Functional assessment of the hip abductors was performed with assessment for the presence of the Trendelenburg sign. Palpation examination of the back, gluteal and hip region was performed to try and reproduce the subject's pain complaint. Friedman's test or Cochran's Q with post hoc comparisons adjusted for multiple comparisons was used to compare differences between healthy controls and people with chronic low back pain for both the affected and unaffected sides. Mann-Whitney U was used to compare differences in prevalence between groups. Hierarchical linear regression was used to identify predictors of LBP in this sample. Gluteus medius is weaker in people with LBP compared to controls or the unaffected side (Friedman's test, p gluteus medius weakness, low back regional tenderness, and male sex were predictive of LBP in this sample. Gluteus medius weakness and gluteal muscle tenderness are common symptoms in people with chronic non-specific LBP. Future investigations should validate these findings with quantitative measures as well as investigate the effect of gluteus medius strengthening in people with LBP.

    Exposure of male C3H mice in utero (from gestational days 8-18) to 85ppm sodium arsenite via the dams' drinking water has previously been shown to increase liver tumor incidence by 2 years of age. However, in our companion study (Ahlborn et al., 2009), continuous exposure to 85ppm sodium arsenic (from gestational day 8 to postnatal day 365) did not result in increased tumor incidence, but rather in a significant reduction (0% tumor incidence). The purpose of the present study was to examine the gene expression responses that may lead to the apparent protective effect of continuous arsenic exposure. Genes in many functional categories including cellular growth and proliferation, gene expression, cell death, oxidative stress, protein ubiquitination, and mitochondrial dysfunction were altered by continuous arsenic treatment. Many of these genes are known to be involved in liver cancer. One such gene associated with rodent hepatocarcinogenesis, Scd1, encodes stearoyl-CoA desaturase and was down-regulated by continuous arsenic treatment. An overlap between the genes in our study affected by continuous arsenic exposure and those from the literature affected by long-term caloric restriction suggests that reduction in the spontaneous tumor incidence under both conditions may involve similar gene pathways such as fatty acid metabolism, apoptosis, and stress response.

    This study was conducted to examine the association of adherence to the Dietary Approaches to Stop Hypertension (DASH)-style diet with incident chronic kidney disease (CKD) among an Iranian population. We followed-up 1630 participants (50.5% women, mean age: 42.8 years) of the Tehran Lipid and Glucose Study for 6.1 years, who were initially free of CKD. Baseline diet was assessed using a valid and reliable 168-item food frequency questionnaire. A DASH-style diet, based on scoring eight components (fruits, vegetables, whole grains, nuts and legumes, low-fat dairy, red and processed meats, sweetened beverages and sodium) was used. Estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet in Renal Disease Study equation and CKD was defined as eGFR DASH-style diet score. The incidence of CKD among those in the top quintile of the DASH-style diet was 30%, 18% lower than those in the bottom quintile. After controlling for age, sex, smoking, total energy intake, body mass index, eGFR, triglycerides, physical activity, hypertension and diabetes, adherence to the DASH-style diet was found to be inversely associated with incident CKD (OR: 0.41; 95% confidence interval: 0.24-0.70). In addition, higher scores of fruits, whole grains, nuts and legumes, sweetened beverages and sodium were inversely associated with incidence of CKD. Results revealed that after 6.1 years of follow-up, adherence to the DASH-style diet was associated with a lower risk of incident CKD among adults. © The Author 2017.

    To investigate the feasibility of implementing a video-game exercise programme for older people with chronic low back pain (LBP). Single-centred single-blinded randomised controlled trial (RCT). Physiotherapy outpatient department in a public hospital in Western Sydney, Australia. We will recruit 60 participants over 55 years old with chronic LBP from the waiting list. Participants will be randomised to receive video-game exercise (n=30) or to remain on the waiting list (n=30) for 8 weeks, with follow up at 3 and 6 months. Participants engaging in video-game exercises will be unsupervised and will complete video-game exercise for 60minutes, 3 times per week. Participants allocated to remain on the waiting list will be encouraged to maintain their usual levels of physical activity. The primary outcomes for this feasibility study will be study processes (recruitment and response rates, adherence to and experience with the intervention, and incidence of adverse events) relevant to the future design of a large RCT. Estimates of treatment efficacy (point estimates and 95% confidence intervals) on pain self-efficacy, care seeking, physical activity, fear of movement/re-injury, pain, physical function, disability, falls-efficacy, strength, and walking speed, will be our secondary outcome measures. Recruitment for this trial began in November 2015. This study describes the rationale and processes of a feasibility study investigating a video-game exercise programme for older people with chronic LBP. Results from the feasibility study will inform on the design and sample required for a large multicentre RCT. Australian New Zealand Clinical Trials Registry: ACTRN12615000703505.

Firstly, LiDAR data is reorganized into grid cell, the algorithm removes ground points through top-hat transform. Then, the vegetation points are extracted by normalized difference vegetation index (NDVI. Thirdly, according to the elevation information of LiDAR points, LBP elevation texture is calculated and achieving precise elimination of vegetation in shadows or surrounding to the buildings. At last, morphological operations are used to fill the holes of building roofs, and region growing for complete building edges. The simulation is based on the complex urban area in Vaihingen benchmark provided by ISPRS, the results show that the algorithm affording higher classification accuracy.

    A major research emphasis has been focused on defining the molecular changes that occur from acute to chronic pain to identify potential therapeutic targets for chronic pain. As the endocannabinoid system is dynamically involved in pain signaling, a plausible mechanism that may contribute to chronic pain vulnerability involves alterations in the amount of circulating endocannabinoids. Therefore, this study sought to examine cannabinoid type 1 (CNR1), type 2 (CNR2) receptors, fatty acid amide hydrolase (FAAH), and the vanilloid receptor (transient receptor potential cation channel subfamily V member 1 [TRPV1]) gene expression profiles among individuals with acute and chronic low back pain (cLBP) at their baseline visit. We also assessed associations among selected single nucleotide polymorphisms (SNPs) of FAAH and CNR2 and measures of somatosensory function and self-report pain measures.Using a previously established quantitative sensory testing protocol, we comprehensively assessed somatosensory parameters among 42 acute LBP, 42 cLBP, and 20 pain-free participants. Samples of whole blood were drawn to examine mRNA expression and isolate genomic DNA for genotyping.CNR2 mRNA was significantly upregulated in all LBP patients compared with controls. However, FAAH mRNA and TRPV1 mRNA were significantly upregulated in cLBP compared with controls. A significant association was observed between FAAH SNP genotype and self-report pain measures, mechanical and cold pain sensitivity among LBP participants. cLBP participants showed increased FAAH and TRPV1 mRNA expression compared with acute LBP patients and controls.Further research to characterize pain-associated somatosensory changes in the context of altered mRNA expression levels and SNP associations may provide insight on the molecular underpinnings of maladaptive chronic pain.

    Full Text Available Low back pain (LBP is a very common syndrome that is associated with the extremely high rate of temporary disability and the development of chronic pain syndrome. In addition to structural changes in the locomotor system, psychological and social factors contribute to the development and maintenance of chronic pain. Drug therapy for chronic LBP frequently gives rise to complications. A physician’s important task in this situation is to prevent pain chronization and to reduce the risk of side effects of treatment. One of the ways to solve this task is to use the vitamin B complex (milgamma along with analgesics and myorelaxants. The review considers the possible effects of combination therapy in patients with LBP and discusses whether it should be used.

    Full Text Available INTRODUCTION: Many risk factors have been identified for chronic low back pain (cLBP, but only one study evaluated their interrelations. We aimed to investigate the frequency of cLBP risk factors and their interrelations in patients consulting their general practitioners (GPs for cLBP. METHODS: A cross-sectional, descriptive, national survey was performed. 3000 GPs randomly selected were asked to include at least one patient consulting for cLBP. Demographic, clinical characteristics and the presence of cLBP risk factors were recorded. The frequency of each cLBP risk factor was calculated and multiple correspondence analysis (MCA was performed to study their interrelations. RESULTS: A total of 2068 GPs (68.9% included at least 1 patient, for 4522 questionnaires analyzed. In the whole sample of patients, the 2 risk factors most commonly observed were history of recurrent LBP (72.1% and initial limitation of activities of daily living (66.4%. For working patients, common professional risk factors were beliefs, that LBP was due to maintaining a specific posture at work (79.0% and frequent heavy lifting at work (65.5%. On MCA, we identified 3 risk-factor dimensions (axes for working and nonworking patients. The main dimension for working patients involved professional risk factors and among these factors, patients' job satisfaction and job recognition largely contribute to this dimension. DISCUSSION: Our results shed in light for the first time the interrelation and the respective contribution of several previously identified cLBP risk factors. They suggest that risk factors representing a "work-related" dimension are the most important cLBP risk factors in the working population.

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

    Chronic low-back pain (LBP) may be related to decreased lumbar multifidus muscle cross-sectional area (CSA). In this study, core stabilization exercises were designed to enhance neuromuscular control and correct multifidus dysfunction. The subjects were healthy women (n = 11) and women with chronic LBP (n = 17). Lumbar multifidus muscle CSAs were measured by ultrasonography. Tests were carried out before training exercises for lumbar stability, and again 4 months and 8 months after training. In women with LBP, the mean multifidus muscle CSA increased by 22% on the right side and 23% on the left side after 8 months of lumbar stabilization training, compared with baseline measurements. In healthy women, mean multifidus muscle CSA increased by 24% on the right side and 23% on the left side, compared with baseline values. A core stabilization exercise program significantly increased multifidus muscle CSAs in both healthy women and women with chronic LBP.

    Full Text Available Bactericidal/permeability-increasing protein (BPI and LPS-binding protein (LBP play an important role in host defence. Current evidence shows that BPI/LBP may be widely existed in different cells and tissue types of animals. A full-length cDNA clone encoding a BPI/LBP homologue (dBPI, 1757bp in size, was characterized in venom gland of the hundred-pace snake Deinagkistrodon acutus. Its deduced amino acid sequence of 417 residues had 13.8%–21.5% identity to BPI like 1(BPIL1 and BPI like 3(BPIL3 of other animals. Conserved cysteine residues which are involved in disulfide bond formation between the final strand of the N-terminal beta sheet and the long alpha helix of BPI are identified as Cys146-Cys183 of dBPI. Phylogenetic tree analysis showed that the BPI/LBP homologues formed five large clusters and dBPI was in a large cluster including BPIL1 and BPIL3. dBPI mRNA shows a tissue specific expression in venom gland. This is the first study to identify the cDNA encoding BPI/LBP homologues from reptiles [Current Zoology 55 (5: –2009].

    Objective To evaluate the incidence rate of Chronic Kidney Disease (CKD) stage 3-5 (persistent decreased kidney function under 60 mL/min per 1.73 m2) among patients with type 2 diabetes over five years, to identify the risk factors associated with CKD, and develop a risk table to predict five-year CKD stage 3-5 risk stratification for clinical use. Design The MADIABETES Study is a prospective cohort study of 3,443 outpatients with type 2 diabetes mellitus, sampled from 56 primary health care centers (131 general practitioners) in Madrid (Spain). Results The cumulative incidence of CKD stage 3-5 at five-years was 10.23% (95% CI = 9.12–11.44) and the incidence density was 2.07 (95% CI = 1.83–2.33) cases per 1,000 patient-months or 2.48 (95% CI = 2.19–2.79) cases per 100 patient-years. The highest hazard ratio (HR) for developing CKD stage 3-5 was albuminuria ≥300 mg/g (HR = 4.57; 95% CI= 2.46-8.48). Furthermore, other variables with a high HR were age over 74 years (HR = 3.20; 95% CI = 2.13–4.81), a history of Hypertension (HR = 2.02; 95% CI = 1.42–2.89), Myocardial Infarction (HR= 1.72; 95% IC= 1.25–2.37), Dyslipidemia (HR = 1.68; 95% CI 1.30–2.17), duration of diabetes mellitus ≥ 10 years (HR = 1.46; 95% CI = 1.14-1.88) and Systolic Blood Pressure >149 mmHg (HR = 1.52; 95% CI = 1.02–2.24). Conclusions After a five-year follow-up, the cumulative incidence of CKD is concordant with rates described in Spain and other countries. Albuminuria ≥ 300 mg/g and age over 74 years were the risk factors more strongly associated with developing CKD (Stage 3-5). Blood Pressure, lipid and albuminuria control could reduce CKD incidence of CKD in patients with T2DM. PMID:25856231

    This retrospective study evaluated the influence of the joint impact of habitual exercise and glycemic control on the incidence of chronic kidney disease (CKD) during a 6-year follow-up period in middle-aged and older males. The study population included 303 males without a history of cardiovascular disease, stroke, renal dysfunction, or dialysis treatment. Their lifestyle behaviors regarding exercise and physical activity were evaluated using a standardized self-administered questionnaire. The participants were divided into four categories according to the performance or non-performance of habitual exercise and the presence or absence of hyperglycemia. After 6 years, 32 subjects (10.6%) developed CKD (estimated glomerular filtration rate exercise and hyperglycemic subjects (log-rank test: p exercise (HR = 2.82, 95% confidence of interval (CI) = 1.07-7.36, p = 0.034) and that in hyperglycemic subjects who did not perform habitual exercise (HR = 5.89, 95% CI = 1.87-16.63, p = 0.003) were significantly higher in comparison to the subjects with a NGT who performed habitual exercise. These results suggest that the habitual exercise and good glycemic control and their combination were associated with the incidence of CKD.

    Vitamin D has emerged as a central player in the immune system, with its deficiency being implicated in the pathogenesis of several autoimmune diseases, including chronic GvHD. This is a retrospective cohort analysis of 166 patients, who underwent allogeneic hematopoietic stem cell transplantation (HSCT) at the Karolinska University Hospital, evaluating GvHD, graft failure, infectious complications and survival after HSCT in relation to pre-transplantation vitamin D levels. Most of the patients were deficient in vitamin D before HSCT (median 42 nmol/L). In multivariate analysis, vitamin D level before HSCT was identified as a significant independent risk factor for development of cGvHD. The increased incidence of cGvHD was not coupled to better disease-free survival; instead there was a trend towards lower overall survival in the vitamin D-deficient patients. In addition, we found a significant correlation between vitamin D deficiency and incidence of CMV disease, with no case of CMV disease occurring in patients with sufficient levels of vitamin D before HSCT. Our results support a role of vitamin D in immune tolerance following HSCT. These findings could be highly relevant for the care of HSCT patients, and prospective, randomized studies on the effect of vitamin D supplementation are therefore needed.

    This study was designed to evaluate whether changes in lifestyle behaviors are correlated with the incidence of chronic kidney disease (CKD). The subjects consisted of 316 men without a history of cardiovascular disease, stroke, or renal dysfunction or dialysis treatment. The following lifestyle behaviors were evaluated using a standardized self-administered questionnaire: habitual moderate exercise, daily physical activity, walking speed, eating speed, late-night dinner, bedtime snacking, skipping breakfast, and drinking and smoking habits. The subjects were divided into four categories according to the change in each lifestyle behavior from baseline to the end of follow-up (healthy-healthy, unhealthy-healthy, healthy-unhealthy and unhealthy-unhealthy). A multivariate analysis showed that, with respect to habitual moderate exercise and late-night dinner, maintaining an unhealthy lifestyle resulted in a significantly higher odds ratio (OR) for the incidence of CKD than maintaining a lifestyle (OR 8.94; 95% confidence interval [CI], 1.10-15.40 for habitual moderate exercise and OR 4.00; 95% CI, 1.38-11.57 for late-night dinner). In addition, with respect to bedtime snacking, the change from a healthy to an unhealthy lifestyle and maintaining an unhealthy lifestyle resulted in significantly higher OR for incidence of CKD than maintaining a healthy lifestyle (OR 4.44; 95% CI, 1.05-13.93 for healthy-unhealthy group and OR 11.02; 95% CI, 2.83-26.69 for unhealthy-unhealthy group). The results of the present study suggest that the lack of habitual moderate exercise, late-night dinner, and bedtime snacking may increase the risk of CKD. Copyright © 2017 The Authors.

    The aim of the study was to analyze the incidence, management and cost associated to hematological and dermatological adverse effects (AE) in chronic hepatitis C patients on triple therapy (TT) with telaprevir (TVR) or boceprevir (BOC). An analysis was made on the data recorded on patients who started treatment with TVR or BOC associated with peginterferon alfa and ribavirin in a 12-week follow-up period. Fifty-three patients were included (TVR n=36; BOC n=17). Thrombocytopenia (83% TVR vs. 88% BOC) followed by neutropenia (89% TVR vs. 82% BOC) were the most common AE. Dermatological AE were observed in 32% of patients. Eleven patients required treatment discontinuation (all of them received TVR), and toxicity was the main reason for discontinuation (64%). The percentage of patients who required supportive treatment for management of AE was 66%. The most used supportive treatment was erythropoietin. Eight patients required emergency health care, and 2 were hospitalized due to AE. Total cost of additional supportive resources was 32,522€ (625 [SD=876]€/patient) (TVR 759 [SD=1,022]€/patient vs. BOC 349 [SD=327]€/patient; P>.05). Patients with gradeiii-iv toxicity required greater supportive care with higher costs, compared to patients with gradei-ii toxicity (849 [SD=1,143]€/patient vs. 387 [SD=397]€/patient; P=.053). The addition of new protease inhibitors to conventional treatment leads to a higher incidence of hematological AE in our study, compared to data described in clinical trials. The elevated incidence of AE involves the use of supportive care, increasing total costs of therapy.

    Background: High serum phosphorus concentrations are associated with an increased risk of cardiovascular disease and progression of chronic kidney disease (CKD). However, the relation between dietary phosphorus intake and CKD development has not been well evaluated. Objective: In this study, we investigated the impact of dietary phosphorus density on the development of incident CKD in a cohort of subjects with normal renal function. Design: Data were retrieved from the Korean Genome and Epidemiology Study, a prospective community-based cohort study. The study cohort consisted of subjects aged 40-69 y, who were followed up biennially from 2001 to 2014. A total of 873 subjects with diabetes mellitus (DM) and 5846 subjects without DM (non-DM) were included in the final analysis. The primary endpoint was incident CKD, defined as a composite of estimated glomerular filtration rate phosphorus density, defined as the ratio of a single-day dietary phosphorus amount to the total daily calorie intake, were 0.51 ± 0.08 mg/kcal in the DM group and 0.51 ± 0.07 mg/kcal in the non-DM group. During the follow-up, CKD newly developed in 283 (32.4%) and 792 subjects (13.5%) in the DM and non-DM groups, respectively. When the subjects were divided into quartiles according to the dietary phosphorus density in each group, the highest quartile was significantly associated with the development of incident CKD by multiple Cox proportional hazard analysis in the DM group ( P = 0.02) but not in the non-DM group ( P = 0.72). Conclusions: High dietary phosphorus density is associated with an increased risk of CKD development in DM patients with normal renal function. The causality in this association needs to be tested in a randomized controlled trial. © 2017 American Society for Nutrition.

Verificou-se que o consumo regular de álcool era predominante nos não usuários de chá verde, quando comparados com os apreciadores da bebida (50% e 35%, respectivamente, faziam uso de álcool. Não foi observado sedentarismo na amostra. Dos apreciadores do chá, 81% não apresentavam doenças crônicas. Já entre os consumidores, observamos um menor percentual de doenças crônicas, especialmente, de hipertensão, porém sem significância estatística.To investigate the probable benefits of Asian dietary habits, including the intake of Camellia sinensis (green tea, in preventing chronic-degenerative diseases. Thirty-four individuals aging from 25 to 84 years from a Japanese community in Rio de Janeiro answered a socioeconomic-cultural questionnaire. Seventy-six percent of the individuals consumed green tea, where 35% consumed it daily and 27% consumed it sporadically. The regular intake of alcohol predominated among the non-consumers of green tea, when compared with green tea consumers (50% and 35%, respectively consumed alcoholic beverages. None of the individuals in the sample had a sedentary lifestyle. Among the individuals who consumed green tea, 81% did not have any chronic illnesses. The consumers of tea presented a lower incidence of chronic diseases, especially hypertension, but it was not statistically significant.

    Full Text Available Low back pain (LBP is a major health problem. Globally it is responsible for the most years lived with disability. The most problematic type of LBP is chronic LBP (pain lasting longer than 3 mo; it has a poor prognosis and is costly, and interventions are only moderately effective. Targeting interventions according to risk profile is a promising approach to prevent the onset of chronic LBP. Developing accurate prognostic models is the first step. No validated prognostic models are available to accurately predict the onset of chronic LBP. The primary aim of this study was to develop and validate a prognostic model to estimate the risk of chronic LBP.We used the PROGRESS framework to specify a priori methods, which we published in a study protocol. Data from 2,758 patients with acute LBP attending primary care in Australia between 5 November 2003 and 15 July 2005 (development sample, n = 1,230 and between 10 November 2009 and 5 February 2013 (external validation sample, n = 1,528 were used to develop and externally validate the model. The primary outcome was chronic LBP (ongoing pain at 3 mo. In all, 30% of the development sample and 19% of the external validation sample developed chronic LBP. In the external validation sample, the primary model (PICKUP discriminated between those who did and did not develop chronic LBP with acceptable performance (area under the receiver operating characteristic curve 0.66 [95% CI 0.63 to 0.69]. Although model calibration was also acceptable in the external validation sample (intercept = -0.55, slope = 0.89, some miscalibration was observed for high-risk groups. The decision curve analysis estimated that, if decisions to recommend further intervention were based on risk scores, screening could lead to a net reduction of 40 unnecessary interventions for every 100 patients presenting to primary care compared to a "treat all" approach. Limitations of the method include the model being restricted to using prognostic

    The high incidence and inconsistencies in diagnostic and therapeutic process of low back pain (LBP) stimulate the continuing search for more efficient treatment modalities. Integration of the information obtained with various therapeutic methods and a holistic approach to the patient seem to be associated with positive outcomes. The aim of this study was to analyze the efficacy of combined treatment with McKenzie method and Muscle Energy Technique (MET), and to compare it with the outcomes of treatment with McKenzie method or standard physiotherapy in specific chronic lumbar pain. The study included 60 men and women with LBP (mean age 44 years). The patients were randomly assigned to 1 of 3 therapeutic groups, which were further treated with: 1) McKenzie method and MET, 2) McKenzie method alone, or 3) standard physiotherapy for 10 days. The extent of spinal movements (electrogoniometry), level of experienced pain (Visual Analogue Scale and Revised Oswestry Pain Questionnaire), and structure of the spinal discs (MRI) were examined prior to the intervention, immediately thereafter, and 3 months after the intervention. McKenzie method enriched with MET had the best therapeutic outcomes. The mobility of cervical, thoracic, and lumbar spine normalized at levels corresponding to 87.1%, 66.7%, and 95% of respective average normative values. Implementation of McKenzie method, both alone and combined with MET, was associated with a significant decrease in Oswestry Disability Index, significant alleviation of pain (VAS), and significantly reduced size of spinal disc herniation. The combined method can be effectively used in the treatment of chronic LBP.

    The current situation in the treatment of chronic myeloid leukaemia (CML) presents a new challenge for attempts to measure the therapeutic results, as the CML patients can experience multiple leukaemia-free periods during the course of their treatment. Traditional measures of treatment efficacy such as leukaemia-free survival and cumulative incidence are unable to cope with multiple events in time, e.g. disease remissions or progressions, and as such are inappropriate for the efficacy assessment of the recent CML treatment. Standard nonparametric statistical methods are used for estimating two principal characteristics of the current CML treatment: the probability of being alive and leukaemia-free in time after CML therapy initiation, denoted as the current cumulative incidence of leukaemia-free patients; and the probability that a patient is alive and in any leukaemia-free period in time after achieving the first leukaemia-free period on the CML treatment, denoted as the current leukaemia-free survival. The validity of the proposed methods is further documented in the data of the Czech CML patients consecutively recorded between July 2003 and July 2009 as well as in simulated data. The results have shown a difference between the estimates of the current cumulative incidence function and the common cumulative incidence of leukaemia-free patients, as well as between the estimates of the current leukaemia-free survival and the common leukaemia-free survival. Regarding the currently available follow-up period, both differences have reached the maximum (12.8% and 20.8%, respectively) at 3 years after the start of follow-up, i.e. after the CML therapy initiation in the former case and after the first achievement of the disease remission in the latter. Two quantities for the evaluation of the efficacy of current CML therapy that may be estimated with standard nonparametric methods have been proposed in this paper. Both quantities reliably illustrate a patient's disease

    Full Text Available BACKGROUND: Few studies have evaluated the association between incident chronic kidney disease (CKD and related complications, especially in elderly population. We attempted to verify the association between GFR and concurrent CKD complications and elucidate the temporal relationship between incident CKD and new CKD complications in a community-based prospective elderly cohort. METHOD: We analyzed the available data from 984 participants in the Korean Longitudinal Study on Health and Aging. Participants were categorized into 6 groups according to eGFR at baseline examination (≥90, 75-89, 60-74, 45-59, 30-44, and <30 ml/min/1.73 m(2. RESULT: The mean age of study population was 76 ± 9.1 years and mean eGFR was 72.3 ± 17.0 ml/min/1.73 m(2. Compared to eGFR group 1, the odds ratio (OR for hypertension was 2.363 (95% CI, 1.299-4.298 in group 4, 5.191 (2.074-12.995 in group 5, and 13.675 (1.611-115.806 in group 6; for anemia, 7.842 (2.265-27.153 in group 5 and 13.019 (2.920-58.047 in group 6; for acidosis, 69.580 (6.770-715.147 in group 6; and for hyperkalemia, 19.177 (1.798-204.474 in group 6. Over a 5-year observational period, CKD developed in 34 (9.6% among 354 participants with GFR ≥ 60 ml/min/1.73 m(2 at basal examination. The estimated mean number of new complications according to analysis of co-variance was 0.52 (95% CI, 0.35-0.68 in subjects with incident CKD and 0.24 (0.19-0.29 in subjects without CKD (p = 0.002. Subjects with incident CKD had a 2.792-fold higher risk of developing new CKD complications. A GFR level of 52.4 ml/min/1.73 m(2 (p = 0.032 predicted the development of a new CKD complication with a 90% sensitivity. CONCLUSION: In an elderly prospective cohort, CKD diagnosed by current criteria is related to an increase in the number of concurrent CKD complications and the development of new CKD complications.

    With a global prevalence of ~9%-12%, low back pain (LBP) is a serious public health issue, associated with high costs for treatment and lost productivity. Chronic LBP (cLBP) involves central sensitization, a neuropathic pain component, and may induce maladaptive coping strategies and depression. Treating cLBP is challenging, and current treatment options are not fully satisfactory. A new BioErodible MucoAdhesive (BEMA ® ) delivery system for buprenorphine has been developed to treat cLBP. The buccal buprenorphine (BBUP) film developed for this product (Belbuca™) allows for rapid delivery and titration over a greater range of doses than was previously available with transdermal buprenorphine systems. In clinical studies, BBUP was shown to effectively reduce pain associated with cLBP at 12 weeks with good tolerability. The most frequently reported side effects with the use of BBUP were nausea, constipation, and vomiting. There was no significant effect on the QT interval vs placebo. Chronic pain patients using other opioids can be successfully rotated to BBUP without risk of withdrawal symptoms or inadequate analgesia. The role of BBUP in managing cLBP remains to be determined, but it appears to be a promising new product in the analgesic arsenal in general.

    Gastrointestinal disturbances are among symptoms commonly reported by individuals diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). However, whether ME/CFS is associated with an altered microbiome has remained uncertain. Here, we profiled gut microbial diversity by sequencing 16S ribosomal ribonucleic acid (rRNA) genes from stool as well as inflammatory markers from serum for cases (n = 48) and controls (n = 39). We also examined a set of inflammatory markers in blood: C-reactive protein (CRP), intestinal fatty acid-binding protein (I-FABP), lipopolysaccharide (LPS), LPS-binding protein (LBP), and soluble CD14 (sCD14). We observed elevated levels of some blood markers for microbial translocation in ME/CFS patients; levels of LPS, LBP, and sCD14 were elevated in ME/CFS subjects. Levels of LBP correlated with LPS and sCD14 and LPS levels correlated with sCD14. Through deep sequencing of bacterial rRNA markers, we identified differences between the gut microbiomes of healthy individuals and patients with ME/CFS. We observed that bacterial diversity was decreased in the ME/CFS specimens compared to controls, in particular, a reduction in the relative abundance and diversity of members belonging to the Firmicutes phylum. In the patient cohort, we find less diversity as well as increases in specific species often reported to be pro-inflammatory species and reduction in species frequently described as anti-inflammatory. Using a machine learning approach trained on the data obtained from 16S rRNA and inflammatory markers, individuals were classified correctly as ME/CFS with a cross-validation accuracy of 82.93 %. Our results indicate dysbiosis of the gut microbiota in this disease and further suggest an increased incidence of microbial translocation, which may play a role in inflammatory symptoms in ME/CFS.

  7. Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trøndelag Health Study.

    Ingrid Heuch

    Full Text Available Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP, but it is not known if there is any causal relationship.The objective was to determine, in a population-based prospective cohort study, whether there is any relation between levels of total cholesterol, high density lipoprotein (HDL cholesterol and triglycerides and the probability of experiencing subsequent chronic (LBP, both among individuals with and without LBP at baseline.Information was collected in the community-based HUNT 2 (1995-1997 and HUNT 3 (2006-2008 surveys of an entire Norwegian county. Participants were 10,151 women and 8731 men aged 30-69 years, not affected by chronic LBP at baseline, and 3902 women and 2666 men with LBP at baseline. Eleven years later the participants indicated whether they currently suffered from chronic LBP.Among women without LBP at baseline, HDL cholesterol levels were inversely associated and triglyceride levels positively associated with the risk of chronic LBP at end of follow-up in analyses adjusted for age only. Adjustment for the baseline factors education, work status, physical activity, smoking, blood pressure and in particular BMI largely removed these associations (RR: 0.96, 95% CI: 0.85-1.07 per mmol/l of HDL cholesterol; RR: 1.16, 95% CI: 0.94-1.42 per unit of lg(triglycerides. Total cholesterol levels showed no associations. In women with LBP at baseline and men without LBP at baseline weaker relationships were observed. In men with LBP at baseline, an inverse association with HDL cholesterol remained after complete adjustment (RR: 0.83, 95% CI: 0.72-0.95 per mmol/l.Crude associations between lipid levels and risk of subsequent LBP in individuals without current LBP are mainly caused by confounding with body mass. However, an association with low HDL levels may still remain in men who are already affected and possibly experience a higher pain intensity.

    This study investigated the association between habitual consumption of allium vegetables (garlic and onion) and the incidence of cardiovascular disease (CVD) outcomes, hypertension (HTN), chronic kidney disease (CKD), and type 2 diabetes (T2D). Adult men and women, participated in the Tehran Lipid and Glucose Study (2006-2008 to 2012-2014), were recruited. Habitual dietary intakes were assessed using a validated semiquantitative food frequency questionnaire. Demographics, anthropometrics, blood pressure, and biochemical variables were evaluated at baseline and during follow-up examinations. Multivariate Cox proportional hazard regression models adjusted for potential confounders were used to estimate the development of CVD outcomes, HTN, CKD, and T2D in relation to allium vegetable intakes. Mean age of participants (44.2% men) was 40.3 ± 14.3 years, at baseline. During an average of 6 years of follow-up, the incidence rate of CVD outcomes, HTN, CKD, and T2D were 3.3, 15.5, 17.9, and 6.7%, respectively. A higher habitual intake of allium vegetables was associated with a 64% reduced risk of CVD outcomes (hazard ratio = 0.36, 95% confidence interval, CI = 0.18-0.71; P for trend = 0.011), 32% lower incidence of CKD (hazard ratio = 0.69, 95% CI = 0.46-0.98; P for trend = 0.11), and 26% decreased HTN development (hazard ratio = 0.74, 95% CI = 0.54-1.00; P for trend = 0.06). No significant association was observed between allium vegetable intakes and the risk of T2D. Allium vegetable intake was related to 6 years' changes of triglyceride levels (β = -0.81, P = 0.01) and creatinine clearance (β = 0.56, P = 0.01). Data of the current study support the available mechanistic findings regarding cardiorenal protective properties of allium vegetables.

    Lipopolysaccharide (LPS), the major component of the outer membrane of Gram-negative bacteria, binds Toll-like receptor 4 (TLR4)-MD2 complex and activates innate immune responses. LPS transfer to TLR4-MD2 is catalyzed by both LPS binding protein (LBP) and CD14. To define the sequential molecular interactions underlying this transfer, we reconstituted in vitro the entire LPS transfer process from LPS micelles to TLR4-MD2. Using electron microscopy and single-molecule approaches, we characterized the dynamic intermediate complexes for LPS transfer: LBP-LPS micelles, CD14-LBP-LPS micelle, and CD14-LPS-TLR4-MD2 complex. A single LBP molecule bound longitudinally to LPS micelles catalyzed multi-rounds of LPS transfer to CD14s that rapidly dissociated from LPB-LPS complex upon LPS transfer via electrostatic interactions. Subsequently, the single LPS molecule bound to CD14 was transferred to TLR4-MD2 in a TLR4-dependent manner. The definition of the structural determinants of the LPS transfer cascade to TLR4 may enable the development of targeted therapeutics for intervention in LPS-induced sepsis.

    We studied the usefulness of serum procalcitonin (PCT), interleukin-6 (IL-6), lipopolysaccharide binding protein (LBP) levels and C-reactive protein (CRP) levels, in differentiating between systemic inflammatory response syndrome (SIRS) and sepsis in critically ill patients. Methods. In this single centre prospective observational study we included all consecutive patients admitted with SIRS or sepsis to the ICU. Blood samples for measuring CRP, PCT, IL-6 and LBP were taken every day until ICU discharge. Results. A total of 76 patients were included, 32 with sepsis and 44 with SIRS. Patients with sepsis were sicker on admission and had a higher mortality. CRP, PCT, IL-6 and LBP levels were significantly higher in patients with sepsis as compared to SIRS. With PCT levels in the first 24 hours after ICU admission 10 ng/mL, sepsis with bacterial infection was very likely (positive predictive value 88%). PCT was best at discriminating between SIRS and sepsis with the highest area under the ROC curve (0.95, 95% CI 0.90-0.99). Discussion. This study showed that PCT is more useful than LBP, CRP and IL-6 in differentiating sepsis from SIRS.

Hysterectomy is a very common gynecological surgery, resulting in chronic post-hysterectomy pain (CPHP, an important pain syndrome. We conducted a prospective cohort study in 216 Asian women who underwent abdominal or laparoscopic hysterectomy for benign conditions. Demographic, psychological, and perioperative data were recorded. Postoperative 4- and 6-month phone surveys were conducted to assess the presence of CPHP and functional impairment. The incidence rates of CPHP at 4 and 6 months were 32% (56/175 and 15.7% (25/159, respectively. Women with CPHP at 4 and 6 months had pain that interfered with their activities of daily living. Independent association factors for CPHP at 4 months were higher mechanical temporal summation score, higher intraoperative morphine consumption, higher pain score in the recovery room, higher pain score during coughing and itching at 24 hours postoperatively, and preoperative pain in the lower abdominal region. Independent association factors for CPHP at 6 months were preoperative pain during sexual intercourse, higher mechanical temporal summation score, and higher morphine consumption during postoperative 24 and 48 hours. In a majority of cases, CPHP resolved with time, but may have significant impact on

    Tapentadol is a novel pain reliever with apparently synergistic dual mechanisms of action, capable of addressing both nociceptive and neuropathic components of chronic pain. As an effective analgesic with good tolerability, tapentadol may be appropriate for patients suffering from severe chronic pain associated with low back pain (LBP) or osteoarthritis (OA). Efficacy studies of tapentadol in populations of patients with severe chronic LBP or OA pain suggest that tapentadol is non-inferior to oxycodone. Its tolerability, especially with respect to gastrointestinal (GI) side effects, may be better than that of other strong opioids in clinical trials and analyses of multiple trials. Patient satisfaction with tapentadol extended release for chronic noncancer pain syndromes is good. Although tapentadol has an opioid component with abuse liability, it appears to be a difficult opioid for tampering with less appeal to abusers than other opioids. For patients with severe LBP and OA pain, tapentadol appears to hold promise as a safe, effective therapeutic option.

    Alexithymia, a lack of emotional awareness, was positively associated with self-reported low back pain (LBP) in cross-sectional studies. We assessed the association of alexithymia with 7.5-year incidence of LBP prospectively in a cohort study of 1207 San Francisco transit operators. Alexithymia was measured by the 20-item Toronto Alexithymia Scale (TAS-20). LBP was assessed by physician-confirmed diagnoses from administrative workers' compensation data. Cox proportional hazards analyses controlled for demographic, behavioral, and physical and psychosocial job factors measured by questionnaire and interview. Of all drivers, 27.7% (n=334) filed compensated claims for LBP injuries with workers' compensation insurance during the 7.5-year observation time. The hazard ratios from the fully adjusted model were 0.73 (0.56-0.96) for the TAS-20 scale and 0.82 (0.69-0.98) for the subscale "difficulty describing feelings." Alexithymia scores did not predict the duration of compensated work disability. In contrast to previous cross-sectional positive associations between alexithymia and LBP, alexithymia is negatively associated with compensated LBP claims. We hypothesize that shame and reporting behavior may explain these inconsistent results.

    Full Text Available The aims of this study were to compare the steadiness index of spinal regions during single-leg standing in older adults with and without chronic low back pain (LBP and to correlate measurements of steadiness index with the performance of clinical balance tests. Thirteen community-dwelling older adults (aged 55 years or above with chronic LBP and 13 age- and gender-matched asymptomatic volunteers participated in this study. Data collection was conducted in a university research laboratory. Measurements were steadiness index of spinal regions (trunk, thoracic spine, lumbar spine, and pelvis during single-leg standing including relative holding time (RHT and relative standstill time (RST, and clinical balance tests (timed up and go test and 5-repetition sit to stand test. The LBP group had a statistically significantly smaller RHT than the control group, regardless of one leg stance on the painful or non-painful sides. The RSTs on the painful side leg in the LBP group were not statistically significantly different from the average RSTs of both legs in the control group; however, the RSTs on the non-painful side leg in the LBP group were statistically significantly smaller than those in the control group for the trunk, thoracic spine, and lumbar spine. No statistically significant intra-group differences were found in the RHTs and RSTs between the painful and non-painful side legs in the LBP group. Measurements of clinical balance tests also showed insignificant weak to moderate correlations with steadiness index. In conclusion, older adults with chronic LBP demonstrated decreased spinal steadiness not only in the symptomatic lumbar spine but also in the other spinal regions within the kinetic chain of the spine. When treating older adults with chronic LBP, clinicians may also need to examine their balance performance and spinal steadiness during balance challenging tests.

    Full Text Available BACKGROUND: Biomass smoke is associated with the risk of chronic obstructive pulmonary disease (COPD, but few studies have elaborated approaches to reduce the risk of COPD from biomass burning. The purpose of this study was to determine whether improved cooking fuels and ventilation have effects on pulmonary function and the incidence of COPD. METHODS AND FINDINGS: A 9-y prospective cohort study was conducted among 996 eligible participants aged at least 40 y from November 1, 2002, through November 30, 2011, in 12 villages in southern China. Interventions were implemented starting in 2002 to improve kitchen ventilation (by providing support and instruction for improving biomass stoves or installing exhaust fans and to promote the use of clean fuels (i.e., biogas instead of biomass for cooking (by providing support and instruction for installing household biogas digesters; questionnaire interviews and spirometry tests were performed in 2005, 2008, and 2011. That the interventions improved air quality was confirmed via measurements of indoor air pollutants (i.e., SO₂, CO, CO₂, NO₂, and particulate matter with an aerodynamic diameter of 10 µm or less in a randomly selected subset of the participants' homes. Annual declines in lung function and COPD incidence were compared between those who took up one, both, or neither of the interventions. Use of clean fuels and improved ventilation were associated with a reduced decline in forced expiratory volume in 1 s (FEV₁: decline in FEV₁ was reduced by 12 ml/y (95% CI, 4 to 20 ml/y and 13 ml/y (95% CI, 4 to 23 ml/y in those who used clean fuels and improved ventilation, respectively, compared to those who took up neither intervention, after adjustment for confounders. The combined improvements of use of clean fuels and improved ventilation had the greatest favorable effects on the decline in FEV₁, with a slowing of 16 ml/y (95% CI, 9 to 23 ml/y. The longer the duration of improved fuel use and

    Chronic pain patients often use complementary medicine (CM) to alleviate their pain; however, little is known about the use of CM by chronic low back pain (cLBP) patients. We investigated the frequency of use of CM by cLBP patients, the perceived effects of these therapies, patients' knowledge regarding CM, and patient-physician communication regarding CM. A cross-sectional survey was conducted from November 2014 to February 2015. A questionnaire was distributed by physicians to 238 consecutive patients consulting for cLBP at the Pain Center of Lausanne University Hospital, Switzerland. Poisson regression model was used to analyze patients' level of knowledge regarding various CMs, and the logistic regression model was used to assess CM use for cLBP. The questionnaire was returned by 168 cLBP patients (response rate: 70.6%). Lifetime prevalence of CM use for cLBP was 77.3%. The most commonly used therapies were osteopathy (48.8%), massage (45.2%) and acupuncture (31.6%), rated for their usefulness on a 0-10 scale as a mean ± SD of 5.4 ± 2.7, 5.9 ± 2.5 and 3.8 ± 3.2, respectively. The CM treatment best known by patients was osteopathy, followed by massage and acupuncture. If their doctors proposed CM as a treatment for cLBP, 78% of participants reported being very or somewhat likely to try CM. Respondents with CM health insurance were more likely to use CM (OR = 2.26; 95%CI: 1.07-4.78; p = 0.031) for cLBP. Respondents having experienced cLBP for more than five years were more likely to use CM to treat their cLBP than respondents having experienced cLBP for one year or less (OR = 2.84; 95%CI: 1.02-7.88; p = 0.044). More than three-quarters of cLBP patients in our sample did use CM to treat their cLBP. The results showed that the most commonly used therapies were not necessarily the highest rated in terms of perceived usefulness. These results highlight the importance of developing integrative pain centers in which patients may obtain advice

    There are limited population-based studies of determinants of physical therapy use for chronic low back pain (LBP) and of the types of treatments received by individuals who see a physical therapist. The purposes of this study were: (1) to identify determinants of physical therapy use for chronic LBP, (2) to describe physical therapy treatments for chronic LBP, and (3) to compare use of treatments with current best evidence on care for this condition. This study was a cross-sectional, population-based telephone survey of North Carolinians. Five hundred eighty-eight individuals with chronic LBP who had sought care in the previous year were surveyed on their health and health care use. Bivariate and multivariable analyses were conducted to identify predisposing, enabling, and need characteristics associated with physical therapy use. Descriptive analyses were conducted to determine the use of physical treatments for individuals who saw a physical therapist. Use of treatments was compared with evidence from systematic reviews. Of our sample, 29.7% had seen a physical therapist in the previous year, with a mean of 15.6 visits. In multivariable analyses, receiving workers' compensation, seeing physician specialists, and higher Medical Outcomes Study 12-Item Short-Form Health Survey questionnaire (SF-12) physical component scores were positively associated with physical therapy use. Having no health insurance was negatively associated with physical therapy use. Exercise was the most frequent treatment received (75% of sample), and traction was the least frequent treatment received (7%). Some effective treatments were underutilized, whereas some ineffective treatments were overutilized. Only one state was examined, and findings were based on patient report. Fewer than one third of individuals with chronic LBP saw a physical therapist. Health-related and non-health-related factors were associated with physical therapy use. Individuals who saw a physical therapist did not

    Full Text Available Abstract Background Chronic non-specific low-back pain (LBP is one of the most common and expensive musculoskeletal disorders in industrialized countries. Similar to other countries in the world, LBP is a common health and socioeconomic problem in Iran. One of the most widely used modalities in the field of physiotherapy for treating LBP is therapeutic ultrasound. Despite its common use, there is still inconclusive evidence to support its effectiveness in this group of patients. This randomised trial will evaluate the effectiveness of continuous ultrasound in addition to exercise therapy in patients with chronic LBP. Methods and design A total of 46 patients, between the ages 18 and 65 years old who have had LBP for more than three months will be recruited from university hospitals. Participants will be randomized to receive continuous ultrasound plus exercise therapy or placebo ultrasound plus exercise therapy. These groups will be treated for 10 sessions during a period of 4 weeks. Primary outcome measures will be functional disability and pain intensity. Lumbar flexion and extension range of motion, as well as changes in electromyography muscle fatigue indices, will be measured as secondary outcomes. All outcome measures will be measured at baseline, after completion of the treatment sessions, and after one month. Discussion The results of this trial will help to provide some evidence regarding the use of continuous ultrasound in chronic LBP patients. This should lead to a more evidence-based approach to clinical decision making regarding the use of ultrasound for LBP. Trial registration Netherlands Trial Register (NTR: NTR2251

    The objective of this study was to assess the association between severe disc degeneration (DD) and low back pain (LBP). A case-control study was conducted with 304 subjects, aged 35-50, recruited in routine clinical practice across six hospitals; 240 cases (chronic LBP patients with a median pain duration of 46 months) and 64 controls (asymptomatic subjects without any lifetime history of significant LBP). The following variables were assessed once, using previously validated methods: gender, age, body mass index (BMI), lifetime smoking exposure, degree of physical activity, severity of LBP, disability, and findings on magnetic resonance (MRI) (disc degeneration, Modic changes (MC), disc protrusion/hernia, annular tears, spinal stenosis, and spondylolisthesis). Radiologists who interpreted MRI were blinded to the subjects' characteristics. A multivariate logistic regression model assessed the association between severe DD and chronic LBP, adjusting for gender, age, BMI, physical activity, MC, disc protrusion/hernia, and spinal stenosis. Severe DD at ≥1 level was found in 46.9 % of the controls and 65.8 % of the cases. Crude odds ratio (95 % CI), for suffering chronic LBP when having severe DD, was 2.06 (1.05; 4.06). After adjusting for "MC" and "disc protrusion/hernia," it was 1.81 (0.81; 4.05). The association between severe DD and LBP ceases to be significant when adjusted for MC and disc protrusion/hernia. These results do not support that DD as a major cause of chronic LBP.

    Marshall, PWM, Desai, I, and Robbins, DW. Core stability exercises in individuals with and without chronic nonspecific low back pain. J Strength Cond Res 25(12): 3404-3411, 2011-The aim of this study was to measure trunk muscle activity during several commonly used exercises in individuals with and without low back pain (LBP). Abdominal bracing was investigated as an exercise modification that may increase the acute training stimulus. After an initial familiarization session, 10 patients with LBP and 10 matched controls performed 5 different exercises (quadruped, side bridge, modified push-up, squat, shoulder flexion) with and without abdominal bracing. Trunk muscle activity and lumbar range of motion (LROM) were measured during all exercises. Muscle activity was measured bilaterally during each exercise from rectus abdominis (RA), external obliques (EO), and lumbar erector spinae (ES) with pairs of surface electrodes. Recorded signals were normalized to a percentage of maximal voluntary contractions performed for each muscle. The ES activity was lower for the LBP group during the quadruped (p exercises in an inconsistent pattern when abdominal bracing was used during exercise. The LROM was no different between groups for any exercise. The lack of worsening of symptoms in the LBP group and similar LROM observed between groups suggest that all exercises investigated in this study are of use in rehabilitating LBP patients. The widespread use of abdominal bracing in clinical practice, whether it be for patients with LBP or healthy individuals, may not be justified unless symptoms of spinal instability are identified.

    Full Text Available The involvement of the primary motor cortex (M1 in chronic low back pain (LBP is a relatively new concept. Decreased M1 excitability and an analgesic effect after M1 stimulation have been recently reported. However, the neurochemical changes underlying these functional M1 changes are unknown. The current study investigated whether neurochemicals specific to neurons and glial cells in both right and left M1 are altered. N-Acetylaspartate (NAA and myo-inositol (mI were measured with proton magnetic resonance spectroscopy in 19 subjects with chronic LBP and 14 healthy controls. We also examined correlations among neurochemicals within and between M1 and relationships between neurochemical concentrations and clinical features of pain. Right M1 NAA was lower in subjects with LBP compared to controls (p = 0.008. Left M1 NAA and mI were not significantly different between LBP and control groups. Correlations between neurochemical concentrations across M1s were different between groups (p = 0.008. There were no significant correlations between M1 neurochemicals and pain characteristics. These findings provide preliminary evidence of neuronal depression and altered neuronal-glial interactions across M1 in chronic LBP.

Insufficient data is currently available to conclusively confirm the analgesic effects of laser acupuncture on LBP. This study evaluated the effectiveness of laser acupuncture plus Chinese cupping in LBP treatment. Methods. Patients with chronic nonspecific LBP were enrolled for a randomized controlled trial and assigned to the laser acupuncture group (laser acupuncture plus Chinese cupping and control group (sham laser plus Chinese cupping. Laser acupuncture (808 nm; 40 mW; 20 Hz; 15 J/cm2 and Chinese cupping were applied on the Weizhong (BL40 and Ashi acupoints for 5 consecutive days. Plasma cortisol levels were assessed before and after the 5-day treatment session. The visual analog scale (VAS scores were recorded at baseline and throughout the 5-day treatment session. Results. After the treatment session, the plasma cortisol levels and VAS scores decreased significantly in both groups. In the laser acupuncture group, the VAS scores decreased significantly on days 4 and 5, and an enhanced reduction in VAS scores was observed. Conclusion. Laser acupuncture plus Chinese cupping at the Weizhong (BL40 and Ashi acupoints effectively reduced pain and inflammation in chronic nonspecific LBP. This therapy could be a suitable option for LBP treatment in clinical settings.

    Conflicting reports exist regarding the prevalence of Modic changes among low back pain (LBP) patients and factors associated with their existence. To assess the prevalence of Modic changes and other findings on lumbar magnetic resonance imaging (MRI) among Spanish adult chronic LBP patients and the patient characteristics and radiological findings associated with Modic changes. A cross-sectional imaging study among chronic LBP patients. Four hundred eighty-seven patients (263 women and 224 men) undergoing lumbar spine MRI examination for chronic LBP. Gender, age, body mass index (BMI), lifetime smoking exposure, degree of physical activity, and image features (disc degeneration, type and extension of Modic changes, disc contour, annular tears, spinal stenosis, and spondylolisthesis). Ten radiologists from six hospitals across six cities in Spain consecutively recruited adult patients in whom lumbar MRI had been prescribed for LBP lasting ≥3 months. Patients' characteristics and imaging findings were assessed through previously validated instruments. A multivariate logistic regression model was developed to assess the features associated with Modic changes. Modic changes were found in 81% of the patients. The most common was Type II (51.3%), affecting only the end plate. Variables associated with Type I changes were disc contour abnormalities, spondylolisthesis, and disc degeneration. The same variables were associated with a higher risk of Type II or any type of Modic changes, as well as being male, and having a higher BMI. Modic changes are found in 81% (95% confidence interval, 77-85) of adult Spanish patients in whom an MRI is prescribed for chronic LBP. Modic changes are more likely to be found in males with a high BMI, who also show disc contour abnormalities, spondylolisthesis, or disc degeneration. Copyright © 2011 Elsevier Inc.

    Osteopathic manipulative treatment (OMT) is often used to treat patients with low back pain (LBP). To identify subgroups of patients with chronic LBP who achieve medium to large treatment effects with OMT based on responder analyses involving pain and functioning outcomes from the OSTEOPAThic Health outcomes In Chronic low back pain (OSTEOPATHIC) Trial. This randomized, double-blind, sham-controlled trial involving 455 patients in Dallas-Fort Worth was conducted from 2006 to 2011. A 100-mm visual analog scale (VAS) for LBP intensity and the Roland-Morris Disability Questionnaire (RMDQ) for back-specific functioning were used to assess primary and secondary outcomes, respectively. Substantial improvement was defined as 50% or greater reduction at week 12 compared with baseline. Cumulative distribution functions for the RR and number-needed-to-treat (NNT) were used to assess response. Medium treatment effects for LBP intensity were observed overall (RR, 1.41; 95% CI, 1.13-1.76; P=.002; NNT, 6.9; 95% CI, 4.3-18.6). However, large treatment effects were observed in patients with baseline VAS scores of 35 mm or greater. Although OMT was not associated with overall substantial improvement in back-specific functioning, patients with baseline RMDQ scores of 7 or greater experienced medium effects, and patients with baseline scores 16 or greater experienced large effects that were significant. The OMT effects for LBP intensity and back-specific functioning were independent of baseline patient demographic characteristics, comorbid medical conditions, and medication use for LBP during the trial. Subgrouping according to baseline levels of chronic LBP intensity and back-specific functioning appears to be a simple strategy for identifying sizeable numbers of patients who achieve substantial improvement with OMT and may thereby be less likely to use more costly and invasive interventions.

    Full Text Available Previous reports documented abnormalities in cognitive functions and decision-making (DM in patients with chronic pain, but these changes are not consistent across studies. Reasons for these discordant findings might include the presence of confounders, variability in chronic pain conditions, and the use of different cognitive tests. The present study was aimed to add evidence in this field, by exploring the cognitive profile of a specific type of chronic pain, i.e.: chronic low back pain (cLBP.Twenty four cLBP patients and 24 healthy controls underwent a neuropsychological battery and we focused on emotional DM abilities by means of Iowa gambling task (IGT. During IGT, behavioral responses and the electroencephalogram (EEG were recorded in 12 patients and 12 controls. Event-related potentials (ERPs were averaged offline from EEG epochs locked to the feedback presentation (4000 ms duration, from 2000 ms before to 2000 ms after the feedback onset separately for wins and losses and the feedback-related negativity (FRN and P300 peak-to-peak amplitudes were calculated. Among cognitive measures, cLBP patients scored lower than controls in the modified card sorting test (MCST and the score in this test was significantly influenced by pain duration and intensity. Behavioural IGT results documented worse performance and the absence of a learning process during the test in cLBP patients compared to controls, with no effect of pain characteristics. ERPs findings documented abnormal feedback processing in patients during IGT.cLBP patients showed poor performance in the MCST and the IGT. Abnormal feedback processing may be secondary to impingement of chronic pain in brain areas involved in DM or suggest the presence of a predisposing factor related to pain chronification. These abnormalities might contribute to the impairment in the work and family settings that often cLBP patients report.

    2011-01-01

    Background The role played by the thoracolumbar fascia in chronic low back pain (LBP) is poorly understood. The thoracolumbar fascia is composed of dense connective tissue layers separated by layers of loose connective tissue that normally allow the dense layers to glide past one another during trunk motion. The goal of this study was to quantify shear plane motion within the thoracolumbar fascia using ultrasound elasticity imaging in human subjects with and without chronic low back pain (LBP). Methods We tested 121 human subjects, 50 without LBP and 71 with LBP of greater than 12 months duration. In each subject, an ultrasound cine-recording was acquired on the right and left sides of the back during passive trunk flexion using a motorized articulated table with the hinge point of the table at L4-5 and the ultrasound probe located longitudinally 2 cm lateral to the midline at the level of the L2-3 interspace. Tissue displacement within the thoracolumbar fascia was calculated using cross correlation techniques and shear strain was derived from this displacement data. Additional measures included standard range of motion and physical performance evaluations as well as ultrasound measurement of perimuscular connective tissue thickness and echogenicity. Results Thoracolumbar fascia shear strain was reduced in the LBP group compared with the No-LBP group (56.4% ± 3.1% vs. 70.2% ± 3.6% respectively, p fascia shear strain and the following variables: perimuscular connective tissue thickness (r = -0.45, p fascia shear strain was ~20% lower in human subjects with chronic low back pain. This reduction of shear plane motion may be due to abnormal trunk movement patterns and/or intrinsic connective tissue pathology. There appears to be some sex-related differences in thoracolumbar fascia shear strain that may also play a role in altered connective tissue function. PMID:21929806

    Despite rapidly increasing intervention, functional disability due to chronic low back pain (cLBP) has increased in recent decades. We often cannot identify mechanisms to explain the major negative impact cLBP has on patients’ lives. Such cLBP is often termed non-specific, and may be due to multiple biologic and behavioral etiologies. Researchers use varied inclusion criteria, definitions, baseline assessments, and outcome measures, which impede comparisons and consensus. The NIH Pain Consortium therefore charged a Research Task Force (RTF) to draft standards for research on cLBP. The resulting multidisciplinary panel recommended using 2 questions to define cLBP; classifying cLBP by its impact (defined by pain intensity, pain interference, and physical function); use of a minimal data set to describe research participants (drawing heavily on the PROMIS methodology); reporting “responder analyses” in addition to mean outcome scores; and suggestions for future research and dissemination. The Pain Consortium has approved the recommendations, which investigators should incorporate into NIH grant proposals. The RTF believes these recommendations will advance the field, help to resolve controversies, and facilitate future research addressing the genomic, neurologic, and other mechanistic substrates of chronic low back pain. We expect the RTF recommendations will become a dynamic document, and undergo continual improvement. Perspective A Task Force was convened by the NIH Pain Consortium, with the goal of developing research standards for chronic low back pain. The results included recommendations for definitions, a minimal dataset, reporting outcomes, and future research. Greater consistency in reporting should facilitate comparisons among studies and the development of phenotypes. PMID:26388962

    Despite rapidly increasing intervention, functional disability due to chronic low back pain (cLBP) has increased in recent decades. We often cannot identify mechanisms to explain the major negative impact cLBP has on patients’ lives. Such cLBP is often termed non-specific, and may be due to multiple biologic and behavioral etiologies. Researchers use varied inclusion criteria, definitions, baseline assessments, and outcome measures, which impede comparisons and consensus. The NIH Pain Consortium therefore charged a Research Task Force (RTF) to draft standards for research on cLBP. The resulting multidisciplinary panel recommended using 2 questions to define cLBP; classifying cLBP by its impact (defined by pain intensity, pain interference, and physical function); use of a minimal data set to describe research participants (drawing heavily on the PROMIS methodology); reporting “responder analyses” in addition to mean outcome scores; and suggestions for future research and dissemination. The Pain Consortium has approved the recommendations, which investigators should incorporate into NIH grant proposals. The RTF believes these recommendations will advance the field, help to resolve controversies, and facilitate future research addressing the genomic, neurologic, and other mechanistic substrates of chronic low back pain. We expect the RTF recommendations will become a dynamic document, and undergo continual improvement. Perspective A Task Force was convened by the NIH Pain Consortium, with the goal of developing research standards for chronic low back pain. The results included recommendations for definitions, a minimal dataset, reporting outcomes, and future research. Greater consistency in reporting should facilitate comparisons among studies and the development of phenotypes. PMID:24787228

    Full Text Available Abstract Background The role played by the thoracolumbar fascia in chronic low back pain (LBP is poorly understood. The thoracolumbar fascia is composed of dense connective tissue layers separated by layers of loose connective tissue that normally allow the dense layers to glide past one another during trunk motion. The goal of this study was to quantify shear plane motion within the thoracolumbar fascia using ultrasound elasticity imaging in human subjects with and without chronic low back pain (LBP. Methods We tested 121 human subjects, 50 without LBP and 71 with LBP of greater than 12 months duration. In each subject, an ultrasound cine-recording was acquired on the right and left sides of the back during passive trunk flexion using a motorized articulated table with the hinge point of the table at L4-5 and the ultrasound probe located longitudinally 2 cm lateral to the midline at the level of the L2-3 interspace. Tissue displacement within the thoracolumbar fascia was calculated using cross correlation techniques and shear strain was derived from this displacement data. Additional measures included standard range of motion and physical performance evaluations as well as ultrasound measurement of perimuscular connective tissue thickness and echogenicity. Results Thoracolumbar fascia shear strain was reduced in the LBP group compared with the No-LBP group (56.4% ± 3.1% vs. 70.2% ± 3.6% respectively, p Conclusion Thoracolumbar fascia shear strain was ~20% lower in human subjects with chronic low back pain. This reduction of shear plane motion may be due to abnormal trunk movement patterns and/or intrinsic connective tissue pathology. There appears to be some sex-related differences in thoracolumbar fascia shear strain that may also play a role in altered connective tissue function.

    It is currently controversial if and in which terms Parkinson's disease (PD) and restless legs syndrome (RLS) are linked in co-morbid association. In a cohort of 106 de novo PD patients (67 male and 39 female, aged 42-83 years), 15 of them developed RLS, which was prospectively assessed at 6-month intervals from the starting of dopamine(DA)ergic therapy. The incidence rate of total RLS was 47 per 1,000 case/person per year and 37 per 1,000 case/person per year after the exclusion of possible "secondary" forms of the disorder (n = 3). These figures are higher than those reported in an incidence study conducted in German general population (Study of Health in Pomerania), in which the method of ascertainment of RLS similar to ours has been used. An incidence rate of total RLS significantly higher than that reported in the above-mentioned study was found in the age ranges 55-64 years and in the age range 45-74 years standardized to European general population 2013  (70 and 53 per 1,000 case/person per year, respectively, p RLS within 24 months from the starting of DAergic medication (median latency 7.5 months). These findings support the view that sustained DAergic therapy could represent the critical factor inducing an increased incidence of RLS in patients with PD and that the latter disease should be regarded as the condition predisposing to the occurrence of the former and not viceversa as previously hypothesized. The mechanism underlying the increased incidence of RLS remains unclear and deserves further investigation.

    Full Text Available Purpose. Chronic low back pain (LBP is often characterized by both nociceptive and neuropathic components. While various monotherapies have been reported of only limited efficacy, combining drugs with different mechanisms of action and targets appears a rational approach. Aim of this systematic review is to assess the efficacy and safety of different combined pharmacological treatments, compared to monotherapy or placebo, for the pharmacological treatment of chronic LBP. Methods. Published papers, written or abstracted in English from 1990 through 2011, comparing combined pharmacological treatments of chronic LBP to monotherapy or placebo were reviewed. Results. Six articles met the inclusion criteria. Pregabalin combined with celecoxib or opioids was shown to be more effective than either monotherapy. Oxycodone-paracetamol versus previous treatments and tramadol-paracetamol versus placebo were also reported as effective, while morphine-nortriptyline did not show any benefit over any single agent. Conclusions. In spite of theoretical advantages of combined pharmacological treatments of chronic LBP, clinical studies are remarkably few. Available data show that combined therapy, including antinociceptive and antineuropathic agents is more effective than monotherapy, with similar side effects.

    Full Text Available Fear of movement (FOM can be acquired by a direct aversive experience such as pain or by social learning through observation and instruction. Excessive FOM results in heightened disability and is an obstacle for recovery from acute, subacute, and chronic low back pain (cLBP. FOM has further been identified as a significant explanatory factor in the Fear Avoidance (FA model of cLBP that describes how individuals experiencing acute back pain may become trapped into a vicious circle of chronic disability and suffering. Despite a wealth of evidence emphasizing the importance of FOM in cLBP, to date, no related neural correlates in patients were found and this therefore has initiated a debate about the precise contribution of fear in the FA model. In the current fMRI study, we applied a novel approach encompassing 1 video clips of potentially harmful activities for the back as FOM inducing stimuli and 2 the assessment of FOM in both, cLBP patients (N = 20 and age- and gender-matched pain-free subjects (N = 20. Derived from the FA model, we hypothesized that FOM differentially affects brain regions involved in fear processing in patients with cLBP compared to pain-free individuals due to the recurrent pain and subsequent avoidance behaviour. The results of the whole brain voxel-wise regression analysis revealed that 1 FOM positively correlated with brain activity in fear-related brain regions such as the amygdala and the insula and 2 Differential effects of FOM between patients with cLBP and pain-free subjects were found in the extended amygdala and in its connectivity to the anterior insula. Current findings support the FOM component of the FA model in cLBP.

    Trunk muscles are designed to fulfill their role of continuous activity throughout the day, but pain and inactivity alter muscles so that they fatigue in normal situations. Lack of endurance of the trunk muscles is an important factor in low back pain (LBP). This paper examines some methods to objectively test endurance of trunk flexor and extensor muscles in static and dynamic situations, and presents results of endurance testing in persons with chronic LBP compared to nonimpaired cohorts. Self perception of fitness affects some test results. Methods for increasing endurance are discussed along with benefits observed from training programs.

    Diabetes mellitus is a strong risk factor for chronic kidney disease and end-stage renal disease. Whether sex differences in chronic kidney disease and end-stage renal disease incidence exist among diabetic patients remains unclear. This systematic review and meta-analysis was conducted to evaluate the relative effect of diabetes on chronic kidney disease and end-stage renal disease risk in women compared with men. We systematically searched Embase, PubMed, and the Cochrane Library for both cohort and case-control studies until October 2015. Studies were selected if they reported a sex-specific relationship between diabetes mellitus and chronic kidney disease or end-stage renal disease. We generated pooled estimates across studies using random-effects meta-analysis after log transformation with inverse variance weighting. Ten studies with data from more than 5 million participants were included. The pooled adjusted risk ratio of chronic kidney disease associated with diabetes mellitus was 3.34 (95 % CI 2.27, 4.93) in women and 2.84 (95 % CI 1.73, 4.68) in men. The data showed no difference in diabetes-related chronic kidney disease risk between the sexes (pooled adjusted women-to-men relative risk ratio was 1.14 [95 % CI 0.97, 1.34]) except for end-stage renal disease-the pooled adjusted women-to men relative risk ratio was 1.38 (95 % CI 1.22, 1.55; p = 0.114, I² = 38.1 %). The study found no evidence of a sex difference in the association between diabetes mellitus and chronic kidney disease. However, the excess risk for end-stage renal disease was higher in women with diabetes than in men with the same condition, from which we assume that the female gender could accelerate the disease progression. Further studies are needed to support this notion and elucidate the underlying mechanisms.

  7. Proline-Based Cyclic Dipeptides from Korean Fermented Vegetable Kimchi and from Leuconostoc mesenteroides LBP-K06 Have Activities against Multidrug-Resistant Bacteria

    Full Text Available Lactobacillus plantarum and Leuconostoc mesenteroides play a prominent role as functional starters and predominant isolates in the production of various types of antimicrobial compound-containing fermented foods, especially including kimchi. In the case of the bioactive cyclic dipeptides, their racemic diastereomers inhibitory to bacteria and fungi have been suggested to come solely from Lactobacillus spp. of these strains. We previously demonstrated the antifungal and antiviral activities of proline-based cyclic dipeptides, which were fractionated from culture filtrates of Lb. plantarum LBP-K10 originated from kimchi. However, cyclic dipeptides have not been identified in the filtrates, either from cultures or fermented subject matter, driven by Ln. mesenteroides, which have been widely used as starter cultures for kimchi fermentation. Most importantly, the experimental verification of cyclic dipeptide-content changes during kimchi fermentation have also not been elucidated. Herein, the antibacterial fractions, including cyclo(Leu-Pro and cyclo(Phe-Pro, from Ln. mesenteroides LBP-K06 culture filtrates, which exhibited a typical chromatographic retention behavior (tR, were identified by using semi-preparative high-performance liquid chromatography and gas chromatography-mass spectrometry. Based on this finding, the proline-based cyclic dipeptides, including cyclo(Ser-Pro, cyclo(Tyr-Pro, and cyclo(Leu-Pro, were additionally identified in the filtrates only when fermenting Chinese cabbage produced with Ln. mesenteroides LBP-K06 starter cultures. The detection and isolation of cyclic dipeptides solely in controlled fermented cabbage were conducted under the control of fermentation-process parameters concomitantly with strong CDP selectivity by using a two-consecutive-purification strategy. Interestingly, cyclic dipeptides in the filtrates, when using this strain as a starter, increased with fermentation time. However, no cyclic dipeptides were

    Full Text Available Abstract Background In the last decade the sub grouping of low back pain (LBP patients according to their likely response to treatment has been identified as a research priority. As with other patient groups, researchers have found few if any factors from the case history or physical examination that are helpful in predicting the outcome of chiropractic care. However, in the wider LBP population psychosocial factors have been identified that are significantly prognostic. This study investigated changes in the components of the LBP fear-avoidance beliefs model in patients pre- and post- their initial visit with a chiropractor to determine if there was a relationship with outcomes at 1 month. Methods Seventy one new patients with lower back pain as their primary complaint presenting for chiropractic care to one of five clinics (nine chiropractors completed questionnaires before their initial visit (pre-visit and again just before their second appointment (post-visit. One month after the initial consultation, patient global impression of change (PGIC scores were collected. Pre visit and post visit psychological domain scores were analysed for any association with outcomes at 1 month. Results Group mean scores for Fear Avoidance Beliefs (FAB, catastrophisation and self-efficacy were all improved significantly within a few days of a patient's initial chiropractic consultation. Pre-visit catastrophisation as well as post-visit scores for catastrophisation, back beliefs (inevitability and self-efficacy were weakly correlated with patient's global impression of change (PGIC at 1 month.

    Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with

    Obesity and type 2 diabetes are nutritional pathologies, characterized by a subclinical inflammatory state. Endotoxins are now well recognized as an important factor implicated in the onset and maintain of this inflammatory state during fat digestion in high-fat diet. As a preventive strategy, lipid formulation could be optimized to limit these phenomena, notably regarding fatty acid profile and PL emulsifier content. Little is known about soybean polar lipid (SPL) consumption associated to oils rich in saturated FA vs. anti-inflammatory omega-3 FA such as α-linolenic acid on inflammation and metabolic endotoxemia. We then investigated in mice the effect of different synthetic diets enriched with two different oils, palm oil or flaxseed oil and containing or devoid of SPL on adipose tissue inflammation and endotoxin receptors. In both groups containing SPL, adipose tissue (WAT) increased compared with groups devoid of SPL and an induction of MCP-1 and LBP was observed in WAT. However, only the high-fat diet in which flaxseed oil was associated with SPL resulted in both higher WAT inflammation and higher circulating sCD14 in plasma. In conclusion, we have demonstrated that LPS transporters LBP and sCD14 and adipose tissue inflammation can be modulated by SPL in high fat diets differing in oil composition. Notably high-flaxseed oil diet exerts a beneficial metabolic impact, however blunted by PL addition. Our study suggests that nutritional strategies can be envisaged by optimizing dietary lipid sources in manufactured products, including fats/oils and polar lipid emulsifiers, in order to limit the inflammatory impact of palatable foods.

    The purpose of this study was to investigate the changes in the thickness of the transversus abdominis (TrA) and internal oblique (IO) muscles in three sitting postures with different levels of stability. The technique of ultrasound imaging was used for individuals with and without chronic low back pain (LBP). A sample of 40 people participated in this study. Subjects were categorised into two groups: with LBP (N = 20) and without LBP (N = 20). Changes in the thickness of tested muscles were normalized under three different sitting postures to actual muscle thickness at rest in the supine lying position and were expressed as a percentage of thickness change. The percentage of thickness change in TrA and IO increased as the stability of the sitting position decreased in both groups. However, the percentages of thickness change in all positions were less in subjects with LBP. There was a significant difference in thickness change in TrA when sitting on a gym ball between subjects with and without LBP but no difference was found when sitting on a chair. There was no significant difference in thickness change in IO in all positions between the two groups. Our findings indicate that difference in the percentage of thickness change in TrA between subjects with and without LBP increases as the stability of sitting position decreases.

    Few studies have assessed the relationship between a subnormal inflammatory status and metabolic syndrome (MS). We therefore designed a cross-sectional and 5-year cohort study to evaluate how a subnormal peripheral blood leukocyte count is related to MS. Participants were recruited from Tianjin Medical University General Hospital-Health Management Centre. Both a baseline cross-sectional (n = 46,179) and a prospective assessment (n = 13,061) were performed. Participants without a history of MS were followed up for 5 years. Leukocyte counts and MS components were assessed at baseline and yearly during the follow-up. Adjusted logistic and Cox proportional hazards regression models were used to assess relationships between the categories of leukocyte counts and MS. The subnormal leukocyte counts group (1,100–3,900 cells/mm3) had the lowest prevalence and incidence of MS. The odds ratio and hazard ratio (95% confidence interval) of the highest leukocyte counts were 1.98 (1.57–2.49) and 1.50 (1.22–1.84) (both P for trend leukocyte counts group after adjusting for potential confounders. This study has shown that subnormal leukocyte counts are independently related to the lowest prevalence and incidence of MS. The findings suggest that it is necessary to restudy and discuss the clinical or preventive value of subnormal leukocyte counts. PMID:24876672

    Full Text Available Abstract Background Complementary and Alternative Medicine (CAM is widely used and popular among patients with primary headache or low back pain (LBP. Aim of the study was to analyze attitudes of headache and LBP patients towards the use of CAM. Methods Two questionnaire-based surveys were applied comparing 432 primary headache and 194 LBP patients. Results In total, 84.75% of all patients reported use of CAM; with significantly more LBP patients. The most frequently-used CAM therapies in headache were acupuncture (71.4%, massages (56.4%, and thermotherapy (29.2%, in LBP thermotherapy (77.4%, massages (62.7%, and acupuncture (51.4%. The most frequent attitudes towards CAM use in headache vs. LBP: "leave nothing undone" (62.5% vs. 52.1%; p = 0.006, "take action against the disease" (56.8% vs. 43.2%; p = 0.006. Nearly all patients with previous experience with CAM currently use CAM in both conditions (93.6% in headache; 100% in LBP. However, the majority of the patients had no previous experience. Conclusion Understanding motivations for CAM treatment is important, because attitudes derive from wishes for non-pharmacological treatment, to be more involved in treatment and avoid side effects. Despite higher age and more permanent pain in LBP, both groups show high use of CAM with only little specific difference in preferred methods and attitudes towards CAM use. This may reflect deficits and unfulfilled goals in conventional treatment. Maybe CAM can decrease the gap between patients' expectations about pain therapy and treatment reality, considering that both conditions are often chronic diseases, causing high burdens for daily life.

The most frequent attitudes towards CAM use in headache vs. LBP: "leave nothing undone" (62.5% vs. 52.1%; p = 0.006), "take action against the disease" (56.8% vs. 43.2%; p = 0.006). Nearly all patients with previous experience with CAM currently use CAM in both conditions (93.6% in headache; 100% in LBP). However, the majority of the patients had no previous experience. Understanding motivations for CAM treatment is important, because attitudes derive from wishes for non-pharmacological treatment, to be more involved in treatment and avoid side effects. Despite higher age and more permanent pain in LBP, both groups show high use of CAM with only little specific difference in preferred methods and attitudes towards CAM use. This may reflect deficits and unfulfilled goals in conventional treatment. Maybe CAM can decrease the gap between patients' expectations about pain therapy and treatment reality, considering that both conditions are often chronic diseases, causing high burdens for daily life.

    Background Low back pain (LBP) is common among office workers. A number of studies have established a relationship between Christianity and physical and mental health outcomes among chronic pain patients. The purpose of this study was to examine the relationship between the religious beliefs and practices of Buddhism and disability and psychological stress in office workers with chronic LBP. Methods A cross-sectional survey was conducted with a self-administered questionnaire delivered by hand to 463 office workers with chronic LBP. Saliva samples were collected from a randomly selected sub-sample of respondents (n=96). Disability due to LBP was assessed using the Roland-Morris Disability Questionnaire and psychological stress was assessed based on salivary cortisol. Two hierarchical regression models were built to determine how much variance in disability and psychological stress could be explained by religious beliefs and practices of Buddhism variables after controlling for potential confounder variables. Results Only 6% of variance in psychological stress was accounted for by the religious beliefs and practices of Buddhism. Those with high religiousness experienced lower psychological stress. No association between the religious beliefs and practices of Buddhism and disability level was found. Depressive symptoms were attributed to both psychological stress and disability status in our study population. Conclusions The findings suggest that, although being religious may improve the psychological condition in workers with chronic LBP, its effect is insufficient to reduce disability due to illness. Further research should examine the role of depression as a mediator of the effect of psychological stress on disability in patients with chronic LBP. PMID:23324474

    Peritoneal dialysis (PD)-related peritonitis remains an important complication in PD patients, potentially causing technique failure and influencing patient outcome. To date, no comprehensive study in the Taiwanese PD population has used a time-dependent statistical method to analyze the factors associated with PD-related peritonitis. Our single-center retrospective cohort study, conducted in southern Taiwan between February 1999 and July 2010, used time-dependent statistical methods to analyze the factors associated with PD-related peritonitis. The study recruited 404 PD patients for analysis, 150 of whom experienced at least 1 episode of peritonitis during the follow-up period. The incidence rate of peritonitis was highest during the first 6 months after PD start. A comparison of patients in the two groups (peritonitis vs null-peritonitis) by univariate analysis showed that the peritonitis group included fewer men (p = 0.048) and more patients of older age (≥65 years, p = 0.049). In addition, patients who had never received compulsory education showed a statistically higher incidence of PD-related peritonitis in the univariate analysis (p = 0.04). A proportional hazards model identified education level (less than elementary school vs any higher education level) as having an independent association with PD-related peritonitis [hazard ratio (HR): 1.45; 95% confidence interval (CI): 1.01 to 2.06; p = 0.045). Comorbidities measured using the Charlson comorbidity index (score >2 vs ≤2) showed borderline statistical significance (HR: 1.44; 95% CI: 1.00 to 2.13; p = 0.053). A lower education level is a major risk factor for PD-related peritonitis independent of age, sex, hypoalbuminemia, and comorbidities. Our study emphasizes that a comprehensive PD education program is crucial for PD patients with a lower education level.

    Little is known about recovery after spinal manipulation in patients with low back pain (LBP). To assess recovery from chronic LBP after a short regimen of osteopathic manipulative treatment (OMT) in a responder analysis of the OSTEOPAThic Health outcomes In Chronic low back pain (OSTEOPATHIC) Trial. A randomized double-blind, sham-controlled trial was conducted to determine the efficacy of 6 OMT sessions over 8 weeks. Recovery was assessed at week 12 using a composite measure of pain recovery (10 mm or less on a 100-mm visual analog scale) and functional recovery (2 or less on the Roland-Morris Disability Questionnaire for back-specific functioning). The RRs and numbers-needed-to-treat (NNTs) for recovery with OMT were measured, and corresponding cumulative distribution functions were plotted according to baseline LBP intensity and back-specific functioning. Multiple logistic regression was used to compute the OR for recovery with OMT while simultaneously controlling for potential confounders. Sensitivity analyses were performed to corroborate the primary results. There were 345 patients who met neither of the recovery criteria at baseline in the primary analyses and 433 patients who met neither or only 1 of these criteria in the sensitivity analyses. There was a large treatment effect for recovery with OMT (RR, 2.36; 95% CI, 1.31-4.24; P=.003), which was associated with a clinically relevant NNT (8.9; 95% CI, 5.4-25.5). This significant finding persisted after adjustment for potential confounders (OR, 2.92; 95% CI, 1.43-5.97; P=.003). There was also a significant interaction effect between OMT and comorbid depression (P=.02), indicating that patients without depression were more likely to recover from chronic LBP with OMT (RR, 3.21; 95% CI, 1.59-6.50; P<.001) (NNT, 6.5; 95% CI, 4.2-14.5). The cumulative distribution functions demonstrated optimal RR and NNT responses in patients with moderate to severe levels of LBP intensity and back-specific dysfunction at

    Full Text Available Abstract Background People who suffer from low back pain (LBP exhibit an abnormal gait pattern, characterized by shorter stride length, greater step width, and an impaired thorax-pelvis coordination which may undermine functional walking. As a result, gait in LBP may require stronger cognitive regulation compared to pain free subjects thereby affecting the degree of automaticity of gait control. Conversely, because chronic pain has a strong attentional component, diverting attention away from the pain might facilitate a more efficient walking pattern. Methods Twelve individuals with LBP and fourteen controls participated. Subjects walked on a treadmill at comfortable speed, under varying conditions of attentional load: (a no secondary task, (b naming the colors of squares on a screen, (c naming the colors of color words ("color Stroop task", and (d naming the colors of words depicting motor activities. Markers were attached to the thorax, pelvis and feet. Motion was recorded using a three-camera SIMI system with a sample frequency of 100 Hz. To examine the effects of health status and attention on gait, mean and variability of stride parameters were calculated. The coordination between thoracic and pelvic rotations was quantified through the mean and variability of the relative phase between those oscillations. Results LBP sufferers had a lower walking speed, and consequently a smaller stride length and lower mean thorax-pelvis relative phase. Stride length variability was significantly lower in the LBP group but no significant effect of attention was observed. In both groups gait adaptations were found under performance of an attention demanding task, but significantly more so in individuals with LBP as indicated by an interaction effect on relative phase variability. Conclusion Gait in LBP sufferers was characterized by less variable upper body movements. The diminished flexibility in trunk coordination was aggravated under the influence of an

    To determine the prevalence and incidence of low back pain (LBP) among workers in the aerospace and defense industry and in a specific company. Claims and demographic data from the Truven Health MarketScan normative database representing more than 1 million workers were drawn from a group of 18 US benchmark companies and compared with one particular company, Lockheed Martin Corporation. The prevalence of LBP in the MarketScan normative group was 15.6% in the final study year (2012), whereas the incidence of new cases was 7.2% and 7.3% in years 2011 and 2012, respectively. Compared with the normative group, the company's prevalence and incidence rates were lower. Women and older workers were more likely to experience LBP compared with men and younger workers. The analysis was used to inform the company's leadership about the health burden of the condition and evaluate alternative treatment options to prevent the incidences and reduce the prevalence of clinical back pain among workers.

    Chronic kidney disease of non-traditional causes is epidemic in Central America, Southern Mexico and other regions of the world such as Sri Lanka, where the origin of the illness is attributed to exposure to agrochemicals and arsenic in soils and groundwater. In Central America, several causes have been suggested for this illness including: high ambient temperatures and chronic dehydration, and toxic effects of agrochemicals. Previous research using step-wise multivariate regression in El Salvador found statistically significant correlation between the spatial distribution of the number of sick people per thousand inhabitants and the percent area cultivated with sugar cane, cotton, and beans, and maximum ambient temperature, with sugar cane cultivation as the most significant factor. This study aims to investigate the possible effects of agricultural activities in the occurrence of this illness looking at heavy metal, arsenic and pesticide contamination in soil, water and sediments of a community located in Bajo Lempa region (Ciudad Romero, El Salvador) and heavily affected by this illness. The Bajo Lempa region is close to Lempa River delta, in the Pacific coast. Ground and surface water, sediment and soil samples were collected in the village where the patients live and in the agricultural areas where they work. With respect to the heavy metals, lead and cadmium where detected in the soils but below the standards for cultivated soils, however, they were not detected in the majority of surface and groundwater. Of the inorganic contaminants, arsenic was present in most soil, sediments, and water samples with some concentrations considerable higher than the standards for cultivated lands and drinking water. Statistically different concentrations in soils were found for the village soils and the cultivated soils, with arsenic higher in the cultivated soils. For the pesticides, results show a significant pollution of soil and groundwater of organochlorine pesticides

    We undertook a study programme at the end of 1991. To start with, we performed some exploratory studies aimed at learning some preliminary lessons on this type of analysis: Assessment of the interest of probabilistic incident analysis; possibility of using PSA scenarios; skills and resources required. At the same time, EPN created a working group whose assignment was to define a new approach for analysis of incidents on NPPs. This working group gave thought to both aspects of Operating Feedback that EPN wished to improve: Analysis of significant incidents; analysis of potential consequences. We took part in the work of this group, and for the second aspects, we proposed a method based on an adaptation of the event-tree method in order to establish a link between existing PSA models and actual incidents. Since PSA provides an exhaustive database of accident scenarios applicable to the two most common types of units in France, they are obviously of interest for this sort of analysis. With this method we performed some incident analyses, and at the same time explores some methods employed abroad, particularly ASP (Accident Sequence Precursor, a method used by the NRC). Early in 1994 EDF began a systematic analysis programme. The first, transient phase will set up methods and an organizational structure. 7 figs

    A considerable portion of chronic low back pain (cLBP) patients lack anatomical abnormality, resist conventional therapeutic interventions, and their symptoms are often complicated with psychological and social factors. Such patients have been reported to show cerebral abnormalities both in anatomy and function by neuroimaging studies. Here we examined differences in cerebral reactivity to a simulated low back pain stimulus between cLBP patients and healthy controls by functional magnetic resonance imaging (fMRI), and their behavioral correlates from a psychophysical questionnaire. Eleven cLBP patients and 13 healthy subjects (HS) were enrolled in this study. After psychophysical evaluation on-going pain with McGill Pain Questionnaire Short Form (MPQ), they underwent whole-brain fMRI in a 3-Tesla MRI scanner while receiving three blocks of 30-s mechanical pain stimuli at the left low back with a 30-s rest in between, followed by a three-dimensional anatomical imaging. Functional images were analyzed with a multi-subject general linear model for blood oxygenation level-dependent (BOLD) signal changes associated with pain. Individual BOLD signal amplitudes at activated clusters were examined for correlation with psychophysical variables. Two in the cLBP and five data sets in the HS groups were excluded from analysis because of deficient or artifactual data or mismatch in age. The HS group showed LBP-related activation at the right insular cortex, right dorsolateral prefrontal cortex (DLPFC), left anterior cingulate cortex (ACC), and left precuneus; and deactivation in a large area over the parietal and occipital cortices, including the bilateral superior parietal cortex. On the other hand, the cLBP group did not show any significant activation at those cortical areas, but showed similar deactivation at the bilateral superior parietal cortex and part of the premotor area. An HS > cLBP contrast revealed significantly less activity at the ACC and DLPFC in the cLBP

    A randomized controlled trial. To investigate the effect of muscle relaxant for muscle blood flow at the trunk muscle in patients with chronic low back pain (LBP). Paraspinal muscle function is widely believed to play a role and considered to be of etiologic significance in LBP, and intramuscular pressure increases and blood flow decreases in the flexion position. Decrease in oxygenated hemoglobin at the trunk muscle is seen in patients with LBP. A total of 74 male patients with LBP lasting more than 6 months were randomized to 3 treatment groups: (1) physical therapy only (control) (n = 25), (2) administration of eperisone hydrochloride (EMPP) for 4 weeks (n = 24), and (3) McKenzie therapy (n = 25). The primary outcome variables, observed at 2 and 4 weeks, are the Japanese Orthopedic Association LBP score, visual analogue scale (VAS), Faces Pain Scale-Revised, and SF-36. Intramuscular oxygenation was evaluated using near-infrared spectroscopy during lumbar extension and flexion, and oxygenated hemoglobin and deoxygenated hemoglobin were compared. VAS was significantly lower at 4 weeks in the McKenzie group than in the control group. There were no significant changes at 2 weeks in all parameters, however, the relative change of oxygenated hemoglobin during lumbar extension at 4 weeks was significantly higher in the EMPP group when compared with the other 2 groups. The relative change of deoxygenated hemoglobin during lumbar flexion showed a significant difference at 4 weeks in the EMPP group when compared with the control group. Administration of EMPP for 4 weeks improved the LBP in VAS, though not as effective as McKenzie therapy. Our data demonstrated the effects of eperisone hydrochloride on paraspinal muscle hemodynamics improving intramuscular oxygenation during lumbar extension and flexion in patients with chronic LBP.

    Thrombosis of native arteriovenous (AV) fistula is an important cause of complications in hemodialysis (HD) patients. The purpose of this study was to investigate the usefulness of measuring circulating fibroblast growth factor-23 (FGF-23) level and paraoxonase-1 (PON1) lactonase activity as potential predictors of native AV fistula thrombosis in chronic HD patients. This study included 83 HD patients (48 with thrombosed and 35 with non-thrombosed native AV fistulas) and 38 healthy volunteers. Serum FGF-23 level was measured using the ELISA technique, while serum PON1 lactonase activity was measured spectrophotometrically using gamma-thiobutyrolactone as a substrate. FGF-23 was significantly increased while PON1 lactonase was markedly decreased in both thrombosed and non-thrombosed HD patients compared with controls (P AV fistulas compared with HD patients with non-thrombosed native AV fistulas (P = 0.001 and 0.002, respectively). A significant negative correlation was found between FGF-23 and PON1 lactonase in HD patients with thrombosed native AV fistulas (r = -0.342, P = 0.017). This study shows a potential value of FGF-23 and PON1 lactonase as predictors of native AV fistula thrombosis in HD patients.

    Full Text Available BACKGROUND: Thoracic surgeries including thoracotomy and VATS are some of the highest risk procedures that often lead to CPSP, with or without a neuropathic component. This retrospective study aims to determine retrospectively the prevalence of CPSP following thoracic surgery, its predicting risk factors, the incidence of neuropathic component, and its impact on quality of life. METHODS: Patients who underwent thoracic surgeries including thoracotomy and VATS between 01/2010 and 12/2011 at the First Affiliated Hospital, School of Medicine, Zhejiang University were first contacted and screened for CPSP following thoracic surgery via phone interview. Patients who developed CPSP were then mailed with a battery of questionnaires, including a questionnaire referenced to Maguire's research, a validated Chinese version of the ID pain questionnaire, and a SF-36 Health Survey. Logistic regression analyses were subsequently performed to identify risk factors for CPSP following thoracic surgery and its neuropathic component. RESULTS: The point prevalence of CPSP following thoracic surgery was 24.9% (320/1284 patients, and the point prevalence of neuropathic component of CPSP was 32.5% (86/265 patients. CPSP following thoracic surgery did not improve significantly with time. Multiple predictive factors were identified for CPSP following thoracic surgery, including age<60 years old, female gender, prolonged duration of post-operative chest tube drainage (≥ 4 days, options of post-operative pain management, and pre-existing hypertension. Furthermore, patients who experienced CPSP following thoracic surgery were found to have significantly decreased physical function and worse quality of life, especially those with neuropathic component. CONCLUSIONS: Our study demonstrated that nearly 1 out of 4 patients underwent thoracic surgery might develop CPSP, and one third of them accompanied with a neuropathic component. Early prevention as well as aggressive

    Background Exposure to traffic-related air pollution (TRAP) is considered to have a carcinogenic effect. The authors previously reported a nonsignificant association between TRAP and cancer risk in a relatively small cohort of myocardial infarction survivors. This study assessed whether TRAP exposure is associated with subsequent cancer in a large cohort of coronary patients. Methods & results Consecutive patients undergoing percutaneous coronary interventions in a major medical centre in central Israel from 2004 to 2014 were followed for cancer through 2015. Residential levels of nitrogen oxides (NO x ) - a proxy for TRAP - were estimated based on a high-resolution national land use regression model. Cox proportional hazards models were constructed to study relationships with cancer. Among 12,784 candidate patients, 9816 had available exposure data and no history of cancer (mean age, 68 years; 77% men). During a median (25th-75th percentiles) follow-up of 7.0 (3.9-9.3) years, 773 incident cases of cancer (8%) were diagnosed. In a multivariable-adjusted model, a 10-ppb increase in mean NO x exposure was associated with hazard ratios (HRs) of 1.07 (95% confidence interval [CI] 1.00-1.15) for all-site cancer and 1.16 (95% CI 1.05-1.28) for cancers previously linked to TRAP (lung, breast, prostate, kidney and bladder). A stronger association was observed for breast cancer (HR = 1.43; 95% CI 1.12-1.83). Associations were slightly strengthened after limiting the cohort to patients with more precise exposure assessment. Conclusion Coronary patients exposed to TRAP are at increased risk of several types of cancer, particularly lung, prostate and breast. As these cancers are amenable to prevention strategies, identifying highly exposed patients may provide an opportunity to improve clinical care.

  15. Development and validation of a questionnaire assessing volitional competencies to enhance the performance of physical activities in chronic low back pain patients

    2011-05-01

    Full Text Available Abstract Background Motivation has long been emphasized as the most important determinant of action. However, there is a substantial gap between people's goals and their attainment. Patients may be motivated and yet unable to take action if their volitional competencies are insufficient. One of the important tasks of volition is goal-maintenance. Research has stressed the importance of a volitional tool, the implementation intentions. Implementation intentions indicate where, when, and how the action leading to the goal will be performed. Forming implementation intentions favours the execution of goal-directed efforts, and reinforces the relationship between intentions and behaviours. Results from various studies clearly suggest that volitional competencies and implementation intentions could play a role in low back pain (LBP patients. However, there is at present no questionnaire allowing assessing the capacity of implementation intentions of physical activities in LBP patients. Methods/Design This study will develop such a questionnaire, using a 3-step approach. A first qualitative step to build categories and generate items; 30 patients suffering chronic LBP will be invited to participate in semi-structured interviews; verbatim and derived items will then be submitted to a panel of experts, using a Delphi method; a second quantitative step to examine the properties of items, and determine the factorial structure of the questionnaire; 100 patients suffering chronic LBP will be recruited to respond to this phase; and third, preliminary psychometric analyses (item-scale correlations, construct validity, reliability; 180 chronic LBP patients will be recruited for this phase of the study. The relationships between implementation intentions and variables affecting physical activity on chronic LBP patients, i.e. pain, physical capacities, fear-avoidance beliefs, kinesiophobia, work status, and level of physical activity will be considered

    Equivalence of laboratory tests over time is important for longitudinal studies. Even a small systematic difference (bias) can result in substantial misclassification. We selected 200 Atherosclerosis Risk in Communities Study participants attending all 5 study visits over 25 years. Eight analytes were remeasured in 2011-2013 from stored blood samples from multiple visits: creatinine, uric acid, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, and high-sensitivity C-reactive protein. Original values were recalibrated to remeasured values with Deming regression. Differences >10% were considered to reflect substantial bias, and correction equations were applied to affected analytes in the total study population. We examined trends in chronic kidney disease (CKD) pre- and postrecalibration. Repeat measures were highly correlated with original values [Pearson r > 0.85 after removing outliers (median 4.5% of paired measurements)], but 2 of 8 analytes (creatinine and uric acid) had differences >10%. Original values of creatinine and uric acid were recalibrated to current values with correction equations. CKD prevalence differed substantially after recalibration of creatinine (visits 1, 2, 4, and 5 prerecalibration: 21.7%, 36.1%, 3.5%, and 29.4%, respectively; postrecalibration: 1.3%, 2.2%, 6.4%, and 29.4%). For HDL cholesterol, the current direct enzymatic method differed substantially from magnesium dextran precipitation used during visits 1-4. Analytes remeasured in samples stored for approximately 25 years were highly correlated with original values, but 2 of the 8 analytes showed substantial bias at multiple visits. Laboratory recalibration improved reproducibility of test results across visits and resulted in substantial differences in CKD prevalence. We demonstrate the importance of consistent recalibration of laboratory assays in a cohort study. © 2015 American Association for Clinical Chemistry.

Results Repeat measures were highly correlated with original values (Pearson’s r>0.85 after removing outliers [median 4.5% of paired measurements]), but 2 of 8 analytes (creatinine and uric acid) had differences >10%. Original values of creatinine and uric acid were recalibrated to current values using correction equations. CKD prevalence differed substantially after recalibration of creatinine (visits 1, 2, 4 and 5 pre-recalibration: 21.7%, 36.1%, 3.5%, 29.4%; post-recalibration: 1.3%, 2.2%, 6.4%, 29.4%). For HDL-cholesterol, the current direct enzymatic method differed substantially from magnesium dextran precipitation used during visits 1–4. Conclusions Analytes re-measured in samples stored for ~25 years were highly correlated with original values, but two of the 8 analytes showed substantial bias at multiple visits. Laboratory recalibration improved reproducibility of test results across visits and resulted in substantial differences in CKD prevalence. We demonstrate the importance of consistent recalibration of laboratory assays in a cohort study. PMID:25952043

    Low back pain (LBP) in older adults is poorly understood because the vast majority of the LBP research has focused on the working aged population. The aim of this study was to compare older adults consulting with chronic LBP to middle aged and young adults consulting with chronic LBP, in terms of their baseline characteristics, and pain and disability outcomes over 1 year. Data were systematically collected as part of routine care in a secondary care spine clinic. At initial presentation patients answered a self-report questionnaire and underwent a physical examination. Patients older than 65 were classified as older adults and compared to middle aged (45-65 years old) and younger adults (17-44 years old) for 10 baseline characteristics. Pain intensity and disability were collected at 6 and 12 month follow-ups and compared between age groups. A total of 14,479 participants were included in the study. Of these 3087 (21%) patients were older adults, 6071 (42%) were middle aged and 5321 (37%) were young adults. At presentation older adults were statistically different to the middle aged and younger adults for most characteristics measured (e.g. less intense back pain, more leg pain and more depression); however, the differences were small. The change in pain and disability over 12 months did not differ between age groups. This study found small baseline differences in older people with chronic LBP compared to middle aged and younger adults. There were no associations between age groups and the clinical course. Small baseline differences exist in older people with chronic low back pain compared to middle aged and younger adults referred to secondary care for chronic low back pain. Older adults present with slightly less intense low back pain but slightly more intense leg pain. Changes in pain intensity and disability over a 12 month period were similar across all age groups. © 2017 European Pain Federation - EFIC®.

    Alterations of the neuromuscular control of the lumbar spine have been reported in patients with chronic low back pain (LBP). During trunk flexion and extension tasks, the reduced myoelectric activity of the low back extensor musculature observed during full trunk flexion is typically absent in patients with chronic LBP. To determine whether pain expectations could modulate neuromuscular responses to experimental LBP to a higher extent in patients with chronic LBP compared with controls. A cross-sectional, case-control study. Twenty-two patients with nonspecific chronic LBP and 22 age- and sex-matched control participants. Trunk flexion-extension tasks were performed under three experimental conditions: innocuous heat, noxious stimulation with low pain expectation, and noxious stimulation with high pain expectation. Noxious stimulations were delivered using a contact heat thermode applied on the skin of the lumbar region (L4-L5), whereas low or high pain expectations were induced by verbal and visual instructions. Surface electromyography of erector spinae at L2-L3 and L4-L5, as well as lumbopelvic kinematic variables were collected during the tasks. Pain was evaluated using a numerical rating scale. Pain catastrophizing, disability, anxiety, and fear-avoidance beliefs were measured using validated questionnaires. Two-way mixed analysis of variance revealed that pain was significantly different among the three experimental conditions (F2,84=317.5; plow back extensor musculature during full trunk flexion was observed in the high compared with low pain expectations condition at the L2-L3 level (F2,84=9.5; ppain catastrophizing in patients with chronic LBP (r=0.54; p=.012). Repeated exposure to pain appears to generate rigid and less variable patterns of muscle activation in patients with chronic LBP, which attenuate their response to pain expectations. Patients with high levels of pain catastrophizing show higher myoelectric activity of lumbar muscles in full flexion

    Altered gastrointestinal (GI) barrier integrity and subsequent microbial translocation may contribute to immune activation in HIV infection. We have reported that rosuvastatin improved several markers of immune activation in HIV+ participants, but the effect of statin treatment on markers of GI barrier dysfunction is unknown. SATURN-HIV is a randomized, double-blind, placebo-controlled trial assessing the effect of rosuvastatin (10mg/daily) on markers of cardiovascular disease, inflammation, and immune activation in ART-treated patients. Gut-barrier integrity was assessed by the surrogate markers intestinal fatty acid binding protein (I-FABP), a marker of enterocyte death, and zonulin-1, a marker of gut epithelial cell function. Levels of lipopolysaccharide binding protein (LBP) were measured as a marker of microbial translocation. Rosuvastatin significantly reduced levels of I-FABP during the treatment period compared to the placebo. There was no effect of rosuvastatin treatment on levels of zonulin or LBP. Baseline levels of LBP were directly related to several markers of immune activation in samples from all participants, including soluble CD163, IP-10, VCAM-1, TNFR-II, and the proportion of CD4+ and CD8+ T cells expressing CD38 and HLA-DR. Many of these relationships, however, were not seen in the statin arm alone at baseline or over time, as inflammatory markers often decreased and LBP levels were unchanged. Forty-eight weeks of rosuvastatin treatment reduced levels of I-FABP, but did not affect levels of zonulin or LBP. The reduction in levels of inflammatory markers that we have reported with rosuvastatin treatment is likely mediated through other mechanisms not related to gut integrity or microbial translocation.

    Full Text Available Abstract Background Although previous research suggests a relationship between chronic low back pain (cLBP and adiposity, this relationship is poorly understood. No research has explored the relationship between abdominal-specific subcutaneous and visceral adiposity with pain and disability in cLBP individuals. The aim of this study therefore was to examine the relationship of regional and total body adiposity to pain and disability in cLBP individuals. Methods A preliminary explorative study design of seventy (n = 70 adult men and women with cLBP was employed. Anthropometric and adiposity measures were collected, including body mass index, waist-to-hip ratio, total body adiposity and specific ultrasound-based abdominal adiposity measurements. Self-reported pain and disability were measured using a Visual Analogue Scale (VAS and the Oswestry Disability Index (ODI questionnaires respectively. Relationships between anthropometric and adiposity measures with pain and disability were assessed using correlation and regression analyses. Results Significant correlations between abdominal to lumbar adiposity ratio (A-L variables and the waist-to-hip ratio with self-reported pain were observed. A-L variables were found to predict pain, with 9.1–30.5 % of the variance in pain across the three analysis models explained by these variables. No relationships between anthropometric or adiposity variables to self-reported disability were identified. Conclusions The findings of this study indicated that regional distribution of adiposity via the A-L is associated with cLBP, providing a rationale for future research on adiposity and cLBP.

    The objective of the study was to establish the specific use of advice and exercise by physiotherapists, for the management of chronic low back pain (LBP). A questionnaire was mailed to a random sample of 600 members of the Irish Society of Chartered Physiotherapists. Open and closed questions were used to obtain information on treatments provided to chronic LBP patients. Respondents' treatment goals were also investigated, along with the typical methods used to assess treatment outcome. Four hundred and nineteen of the sample returned the questionnaire; 280/419 (67%) indicated that they currently treated LBP of which 76% (n=214) were senior grade therapists. Advice and exercise, respectively, were the treatments most frequently used for chronic LBP: advice was most commonly delivered as part of an exercise programme, with strengthening (including core stability) the most frequently used exercise type. Supervision of exercise and follow-up advice were underutilised with respect to the recommendations of relevant clinical guidelines. Pain relief was an important treatment goal. Emphasis on exercise programme supervision, incorporating reassurance that its safe to stay active and 'hurt does not mean harm', must be more effectively disseminated and promoted in practice. The influence of follow-up advice on exercise adherence warrants further investigation.

    The Oswestry Disability Index (ODI) is one of the most widely used questionnaires that assess disability in patients with low back pain (LBP). Responsiveness is both an important psychometric property of an instrument and a key issue for clinicians when choosing suitable outcome measures. The objective of this study was to examine the responsiveness of the Chinese version of the ODI (ODI-Chinese) for subjects with chronic LBP following a physical therapy program. In total, 76 patients with chronic LBP completed the ODI-Chinese, a visual analog scale (VAS) of pain, and the Chinese version of Short Form-36 (SF-36) before and after treatment. All patients also completed a global perception of change Likert scale in condition after the program. The scale was collapsed to produce a dichotomous variable outcome, improved or non-improved. The responsiveness of the instruments was determined using the standardized response means (SRM) and receiver operating characteristics (ROC). After treatment, 56 patients considered themselves to be improved. The SRM of the ODI-Chinese was -1.2 in the improved group and -0.4 in the non-improved group. The area of the ROC curve for the ODI-Chinese was 0.77 (95% CI 0.66-0.89). Therefore, the Chinese version of the ODI is both responsive and appropriate for use in chronic LBP patients after conservative therapy.

    Patients' beliefs about the origin of their pain and their cognitive processing of pain-related information have both been shown to be associated with poorer prognosis in low back pain (LBP), but the relationship between specific beliefs and specific cognitive processes is not known. The aim of this study was to examine the relationship between diagnostic uncertainty and recall bias in 2 groups of chronic LBP patients, those who were certain about their diagnosis and those who believed that their pain was due to an undiagnosed problem. Patients (N=68) endorsed and subsequently recalled pain, illness, depression, and neutral stimuli. They also provided measures of pain, diagnostic status, mood, and disability. Both groups exhibited a recall bias for pain stimuli, but only the group with diagnostic uncertainty also displayed a recall bias for illness-related stimuli. This bias remained after controlling for depression and disability. Sensitivity analyses using grouping by diagnosis/explanation received supported these findings. Higher levels of depression and disability were found in the group with diagnostic uncertainty, but levels of pain intensity did not differ between the groups. Although the methodology does not provide information on causality, the results provide evidence for a relationship between diagnostic uncertainty and recall bias for negative health-related stimuli in chronic LBP patients.

    A randomized controlled trial. To investigate feed-forward activation or timing of abdominal muscle activation in response to rapid shoulder flexion after 8 weeks with core stability exercises, sling exercises, or general exercises in chronic nonspecific low back pain (LBP) patients. Delayed onset in abdominal muscles has been associated with LBP. Low load exercises to volitionally activate the transversus abdominis were introduced to restore trunk muscle activation deficits. More forceful co-contraction exercises have been advocated by others. This study explored whether abdominal muscle onset changed after low-load core stability exercises, high-load sling exercises, or general exercises. Subjects (N = 109) with chronic nonspecific LBP of at least 3 months' duration were randomly assigned to 8 weekly treatments with low-load core stability exercises, high-load stabilizing exercises in slings, or general exercises in groups. Primary outcome was onset recorded bilaterally by m-mode ultrasound imaging in the deep abdominal muscles in response to rapid shoulder flexion. No or small changes were found in onset after treatment. Baseline adjusted between group differences showed a 15 ms (95% confidence interval [CI], 1-28; P = 0.03) and a 19 ms (95% CI, 5-33; P core stability and general exercises, respectively, but on 1 side only. There was no association between changes in pain and onset over the intervention period (R ≤ 0.02). Abdominal muscle onset was largely unaffected by 8 weeks of exercises in chronic LBP patients. There was no association between change in onset and LBP. Large individual variations in activation pattern of the deep abdominal muscles may justify exploration of differential effects in subgroups of LBP.

    Ergonomic factors are often accompanied by the appearance of LBP. The restrictions within the musculoskeletal system cause disorders in muscle synergies, which is expressed by an increase in the angular velocity of the COG. In patients with chronic back pain syndrome, selected stretching therapy techniques improves the range of motion of the spine and reduces pain.

    The aim was to compare core stability and general exercises (GEs) in chronic low back pain (LBP) patients based on lumbopelvic stability (LPS) assessment through three endurance core stability tests. There is a controversy about preference of core stability exercise (CSE) over other types of exercise for chronic LBP. Studies which have compared these exercises used other outcomes than those related to LPS. As it is claimed that CSE enhances back stability, endurance tests for LPS were used. A 16-session CSE program and a GE program with the same duration were conducted for two groups of participants. Frequency of interventions for both groups was three times a week. Forty-three people (aged 18-60 years) with chronic non-specific LBP were alternately allocated to core stability (n = 22) or GE group (n = 21) when admitted. The primary outcomes were three endurance core stability tests including: (1) trunk flexor; (2) trunk extensor; and (3) side bridge tests. Secondary outcomes were disability and pain. Measurements were taken at baseline and the end of the intervention. After the intervention, test times increased and disability and pain decreased within groups. There was no significant difference between two groups in increasing test times (p = 0.23 to p = 0.36) or decreasing disability (p = 0.16) and pain (p = 0.73). CSE is not more effective than GE for improving endurance core stability tests and reducing disability and pain in chronic non-specific LBP patients.

    Segmentation of lesions in ultrasound images is widely used for preliminary diagnosis. In this paper, we develop an automatic segmentation algorithm for multiple types of lesions in ultrasound images. The proposed method is able to detect and segment lesions automatically as well as generate accurate segmentation results for lesion regions. In the detection step, two saliency detection frameworks which adopt global image information are designed to capture the differences between normal and abnormal organs as well as these between lesions and the normal tissues around them. In the segmentation step, three types of local information, i.e., image intensity, improved local binary patterns (LBP) features, and an edge indicator, are embedded into a modified level set framework to carry out the segmentation task. The cyst and carcinoma regions in the ultrasound images of the human kidneys can be automatically detected and segmented by using the proposed method. The efficiency and accuracy of the method are validated by quantitative evaluations and comparative measurements with three well-recognized segmentation methods. Specifically, the average precision and dice coefficient of the proposed method in segmenting renal cysts are 95.33% and 90.16%, respectively, while those in segmenting renal carcinomas are 94.22% and 91.13%, respectively. The average precision and dice coefficient of the proposed method are higher than those of three compared segmentation methods. The proposed method can efficiently detect and segment the renal lesions in ultrasound images. In addition, since the proposed method utilizes the differences between normal and abnormal organs as well as these between lesions and the normal tissues around them, it can be possibly extended to deal with lesions in other organs of ultrasound images as well as lesions in medical images of other modalities. © 2017 American Association of Physicists in Medicine.

    Full Text Available Low back pain (LBP is a common condition in individuals which experienced psychology and physical trauma. LBP is usually found in persons with lower-limb amputation (LLA, as the most common sign of somatisation or inappropriately made prostheses. Our goal was to investigate cases of chronic pain syndrome in persons with LLA and to determine factors, which influence their functional inability due to LBP. Pain after LLA has been studied. 37 persons, including 26 war veterans (70.2 % and 11 (29.8 % civilians with LLA due to an illness, were examined. All participants gave their informed consent and filled Oswestry index of disability due to chronic LBP, divided into 10 sections with 6 questions each, with marks in the range 0-5. The average age of 37 analyzed participants with LLA was 46.2+-10.92 years. 30 participants (81.1 % were married, 4 (10.8 % were single and 3 (8.1 % were widows. 27 (73.0 % participants had below the knee amputation, 5 (13.5 % had above the knee amputation and 5 (13.5 % had foot amputation. 33 (89.6 % participants experienced chronic LBP in the last 2-10 years and 4 (10.8 % did not have pains. According to Oswestry index for chronic pain higher level of social functionality was found in civilian amputees than in war veterans (p<0.05. Married civilian amputees have higher level of disability during seating (p<0.01, sleeping (p<0.01 and traveling (p<0.05. Higher level of social disorder among civilian amputees is due to the fact that they belong to older group of participants which usually have social integration at the lower degree. More serious problems during seating, traveling and sleeping among this group are probably due to co morbidity. Chronic LBP was found among 89.6 % of the participants. Higher level of social disorder, problems during seating, traveling and sleeping were identified in the civilian amputees and the married participants.

    To review the effects of core stability exercise or general exercise for patients with chronic low back pain (LBP). Exercise therapy appears to be effective at decreasing pain and improving function for patients with chronic LBP in practice guidelines. Core stability exercise is becoming increasingly popular for LBP. However, it is currently unknown whether core stability exercise produces more beneficial effects than general exercise in patients with chronic LBP. Published articles from 1970 to October 2011 were identified using electronic searches. For this meta-analysis, two reviewers independently selected relevant randomized controlled trials (RCTs) investigating core stability exercise versus general exercise for the treatment of patients with chronic LBP. Data were extracted independently by the same two individuals who selected the studies. From the 28 potentially relevant trials, a total of 5 trials involving 414 participants were included in the current analysis. The pooling revealed that core stability exercise was better than general exercise for reducing pain [mean difference (-1.29); 95% confidence interval (-2.47, -0.11); P = 0.003] and disability [mean difference (-7.14); 95% confidence interval (-11.64, -2.65); P = 0.002] at the time of the short-term follow-up. However, no significant differences were observed between core stability exercise and general exercise in reducing pain at 6 months [mean difference (-0.50); 95% confidence interval (-1.36, 0.36); P = 0.26] and 12 months [mean difference (-0.32); 95% confidence interval (-0.87, 0.23); P = 0.25]. Compared to general exercise, core stability exercise is more effective in decreasing pain and may improve physical function in patients with chronic LBP in the short term. However, no significant long-term differences in pain severity were observed between patients who engaged in core stability exercise versus those who engaged in general exercise. http

    This paper summarizes evidence of long-term effectiveness of physiotherapy exercise therapy for chronic low back pain (LBP). A literature search was undertaken for experimental studies (2001-2007), which reported any post-intervention (follow-up) outcomes. Studies were critically appraised using the PEDro instrument. Comparative statistics were calculated, relative to the type of follow-up outcome data. Fifteen moderate quality trials were included [mean PEDro score 7.7, SD 1.3 (range 5-10)]. Nine trials reported pain scales, and six reported LBP reoccurrence. Trials which reported on pain scales at 6-month follow-up found significant differences in favour of exercise [standardized mean differences -0.57, 95%CI -0.75 to -0.39 (555 participants)]. At 12-month follow-up, a small pain scale benefit from exercise persisted [standardized mean differences -0.25, 95%CI -0.44 to 0.06 (434 participants)]. There was unconvincing evidence of exercise effectiveness on pain scales after this time. Three of the four trials which reported dichotomous outcomes at 6-month follow-up demonstrated large clinical benefits of exercise (relative risk reduction of reoccurrence 45-246%, absolute risk reduction of reoccurrence 36-42 for every 100 patients; and number needed to treat approximating 3, to prevent one patient suffering a LBP recurrence). The effect of exercise on LBP reoccurrence was variably reported beyond 6 months. Exercise programmes are effective for chronic LBP up to 6 months after treatment cessation, evidenced by pain score reduction and reoccurrence rates. The way in which follow-up data are reported assists clinical interpretation of research findings.

  14. Vertical heterophoria and postural control in nonspecific chronic low back pain.

    Full Text Available The purpose of this study was to test postural control during quiet standing in nonspecific chronic low back pain (LBP subjects with vertical heterophoria (VH before and after cancellation of VH; also to compare with healthy subjects with, and without VH. Fourteen subjects with LBP took part in this study. The postural performance was measured through the center of pressure displacements with a force platform while the subjects fixated on a target placed at either 40 or 200 cm, before and after VH cancellation with an appropriate prism. Their postural performance was compared to that of 14 healthy subjects with VH and 12 without VH (i.e. vertical orthophoria studied previously in similar conditions. For LBP subjects, cancellation of VH with a prism improved postural performance. With respect to control subjects (with or without VH, the variance of speed of the center of pressure was higher, suggesting more energy was needed to stabilize their posture in quiet upright stance. Similarly to controls, LBP subjects showed higher postural sway when they were looking at a target at a far distance than at a close distance. The most important finding is that LBP subjects with VH can improve their performance after prism-cancellation of their VH. We suggest that VH reflects mild conflict between sensory and motor inputs involved in postural control i.e. a non optimal integration of the various signals. This could affect the performance of postural control and perhaps lead to pain. Nonspecific chronic back pain may results from such prolonged conflict.

    Modic changes (MC) are associated with low back pain (LBP), but effective treatments are lacking. The aim of this randomized, placebo-controlled, double-blinded trial was to evaluate the efficacy of zoledronic acid (ZA) for chronic LBP among patients with MC in magnetic resonance imaging (MRI). Inclusion criteria were LBP lasting ≥3 months, with an intensity of ≥6 on a 10-cm VAS or an Oswestry Disability Index (ODI) of ≥30%, and MC in MRI. Patients were randomized into single intravenous infusion of ZA 5 mg (n = 20), or placebo (n = 20) groups. The primary outcome was LBP intensity, secondary outcomes leg pain intensity, ODI, health-related quality of life (RAND-36), lumbar flexibility, sick leaves and use of pain medication. The treatment differences at one month and one year were analysed using ANCOVA with adjustment for the baseline score. The mean difference (MD) between the groups in the primary outcome, intensity of LBP, was 1.4 (95% confidence intervals (CI) 0.01 to 2.9) in favour of ZA at one month. We observed no significant between-group difference in the intensity of LBP at one year (MD 0.7; 95% CI -1.0 to 2.4) or in secondary outcomes at any time point except that 20% of patients in the ZA group used non-steroidal anti-inflammatory drugs at one year compared to 60% in the placebo group (P = 0.022). Acute phase reactions (fever, flu-like symptoms, arthralgia) emerged in 95% of the patients in the ZA group, compared to 35% in the placebo group. ZA was effective in reducing the intensity of LBP in the short term and in reducing the use of NSAIDs within the time span of one year among patients with chronic LBP and MC confirmed in MRI. Although the results seem encouraging, larger studies are required to analyse the effectiveness and safety of ZA for patients with MC. ClinicalTrial.gov identifier NCT01330238.

Recent data suggest that killer cell immunoglobulin-like receptor (KIR) regulated natural killer cell (NK cell) activity may contribute to graft versus leukemia (GvL) effects and graft versus host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This case-control study aims to evaluate the effects of both aKIR and iKIR donor-recipient genotype matching on the outcomes of T cell replete HLA-identical sibling allo-HSCTs in a homogenous young patient population with myeloid leukemias. Five transplant outcomes including relapse rate (RR), disease-free survival (DFS), overall survival (OS), cumulative incidences of acute GvHD (aGvHD), and chronic GvHD (cGvHD) are investigated. Out of 96 HLA-identical sibling donor-recipient pairs, 34 were matched for activating KIR (aKIR), 38 for inhibitory KIR (iKIR), and 20 for both aKIR and iKIR. Fourty-four pairs were mismatched for both iKIR and aKIR. In univariate analysis, aKIR-matching resulted with a decrease in relapse rate (RR) (hazard ratio [HR]: 0.4; p = 0.04) and an increase in disease-free survival (DFS) (HR: 0.5; p = 0.03). In addition, cGvHD ocurred less frequently in the aKIR-matched (odds ratio [OR]: 0.4; p = 0.04) or iKIR-matched (OR: 0.3; p = 0.009) cohorts. Matching for both aKIR and iKIR was also associated with a decrease in cGvHD incidence (OR: 0.3; p = 0.02). iKIR-matching had no effects on RR, OS, or DFS. Analysis of donor haplotype effects showed haplotype-BB to have a tendency towards reduced relapse rate (HR: 0.4; p = 0.08) and better OS (HR: 0.4; p = 0.04); haplotype-Bx to increase the incidence of cGvHD (OR: 4.1; p = 0.03). In multivariate analysis, DFS advantage remained significant for aKIR-matching (HR: 0.5; p = 0.04); cGvHD incidence was reduced in the presence of iKIR-match (OR: 0.3; p = 0

    Obesity is frequently associated with various musculoskeletal disorders including chronic low back pain (cLBP). Osteopathy is a discipline emphasizing the conservative treatment of the disease in an olistic vision. We designed a randomized controlled study to investigate whether Osteopathic Manipulative Treatment (OMT) combined with specific exercises (SE) is more effective than SE alone in obese patients with cLBP. nineteen obese females with cLBP, randomized into 2 groups: SE + OMT and SE were studied during the forward flexion of the spine using an optoelectronic system. A biomechanical model was developed in order to analyse kinematics and define angles of clinical interest. kinematic of the thoracic and lumbar spine and pelvis during forward flexion, pain according to a visual analogue scale (VAS), Roland Morris Disability Questionnaire and Oswestry Low Back Pain Disability Questionnaire. significant effects on kinematics were reported only for OMT + SE with an improvement in thoracic range of motion of nearly 20%. All scores of the clinical scales used improved significantly. The greatest improvements occurred in the OMT + SE group. combined rehabilitation treatment including Osteopathic Manipulative Treatment (OMT + SE) showed to be effective in improving biomechanical parameters of the thoracic spine in obese patients with cLBP. Such results are to be attributed to OMT, since they were not evident in the SE group. We also observed a reduction of disability and pain. The clinical results should be considered preliminary due to the small sample size. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Note from PTJ's Editor in Chief: Both investigators and readers get frustrated reading research on low back pain because of different definitions of “chronic” and different outcome measures. Lack of consensus on study methods makes it difficult to determine if contradictory findings are based on different methods or different interventions; lack of consensus also prevents synthesis across studies. Dr. Partap Khalsa, Deputy Director, National Center for Complementary and Integrative Health, announced the release of Research Standards for Chronic Low Pain, and the hope is that future investigations will adopt them and reduce variability in research reporting. The task force on research standards was an international, multidisciplinary team including Anthony Delitto, PT, PhD, FAPTA. Its findings have been published in leading pain journals. PTJ is among the first professional journals to share the report with its readers. Despite rapidly increasing intervention, functional disability due to chronic low back pain (cLBP) has increased in recent decades. We often cannot identify mechanisms to explain the major negative impact cLBP has on patients' lives. Such cLBP is often termed non-specific and may be due to multiple biologic and behavioral etiologies. Researchers use varied inclusion criteria, definitions, baseline assessments, and outcome measures, which impede comparisons and consensus. Therefore, NIH Pain Consortium charged a Research Task Force (RTF) to draft standards for research on cLBP. The resulting multidisciplinary panel recommended using 2 questions to define cLBP; classifying cLBP by its impact (defined by pain intensity, pain interference, and physical function); use of a minimum dataset to describe research participants (drawing heavily on the PROMIS methodology); reporting “responder analyses” in addition to mean outcome scores; and suggestions for future research and dissemination. The Pain Consortium has approved the recommendations, which

    Insomnia, which is very common in patients with chronic low back pain (LBP), has long been viewed as a pain symptom that did not merit specific treatment. Recent data suggest that adding insomnia therapy to pain-targeted treatment should improve outcome; however, this has not been empirically tested in LBP or in any pain condition treated with a standardized pain medication regimen. We sought to test the hypothesis that adding insomnia therapy to pain-targeted treatment might improve sleep and pain in LBP. Double-blind, placebo-controlled, parallel-group, 1-mo trial. Duke University Medical Center Outpatient Sleep Clinic. Fifty-two adult volunteers with LBP of at least 3 mo duration who met diagnostic criteria for insomnia (mean age: 42.5 y; 63% females). Subjects were randomized to eszopiclone (ESZ) 3 mg plus naproxen 500 mg BID or matching placebo plus naproxen 500 mg twice a day. ESZ SIGNIFICANTLY IMPROVED TOTAL SLEEP TIME (MEAN INCREASE: ESZ, 95 min; placebo, 9 min) (primary outcome) and nearly all sleep measures as well as visual analog scale pain (mean decrease: ESZ, 17 mm; placebo, 2 mm) (primary pain outcome), and depression (mean Hamilton Depression Rating Scale improvement ESZ, 3.8; placebo, 0.4) compared with placebo. Changes in pain ratings were significantly correlated with changes in sleep. The addition of insomnia-specific therapy to a standardized naproxen pain regimen significantly improves sleep, pain, and depression in patients with chronic low back pain (LBP). The findings indicate the importance of administering both sleep and pain-directed therapies to patients with LBP in clinical practice and provide strong evidence that improving sleep disturbance may improve pain. clinicaltrials.gov identifier: NCT00365976.

  2. The association between the history of cardiovascular diseases and chronic low back pain in South Koreans: a cross-sectional study.

    Full Text Available BACKGROUND: Cardiovascular disease and related risk factors have been suggested as a mechanism leading to atherosclerosis of the lumbar vessels and consequent lumbar pain or sciatica. But there is continued controversy concerning its generalization. This study examined whether cardiovascular disease or its risk factors were associated with chronic low back pain (cLBP in Koreans. METHODS: Health surveys and examinations were conducted on a nationally representative sample (n = 23,632 of Koreans. A total of 13,841 eligible participants (aged 20 to 89 years were examined to determine the association between cardiovascular disease, the Framingham risk score, major cardiovascular risk factors (blood pressure, diabetes, cholesterol, and smoking habits and chronic LBP. RESULTS: The total prevalence of cLBP was 16.6% (men: 10.8%, women: 21.1% and that in patients with a history of cardiovascular diseases was 36.6% (men: 26.5%, women: 47.1%. The results showed that patients' medical history of cardiovascular disease was significantly associated with cLBP in both men and women when adjusted for covariates (men: OR 2.16; 95%CI 1.34∼3.49; women: OR 2.26; 95%CI 1.51∼3.38. No association was observed between cLBP and the Framingham risk score, medication for hyperlipemia, hypertension, diabetes, and major cardiovascular risk factors (systolic blood pressure, total cholesterol, high density lipoprotein cholesterol, triglycerides, glucose and smoking habits in either men or women. CONCLUSIONS: The prevalence of cLBP is correlated to a history of cardiovascular disease, but not to the major cardiovascular risk factors from the Framingham study. Further studies on whether these results were affected by psychological factors in patients with a history of cardiovascular diseases or whether new potential risk factors from the artery atherosclerosis hypothesis applying to Koreans exist are needed.

    This study aimed to examine predictors and clinical outcomes of periprocedural myocardial infarction (PMI) after chronic total occlusion (CTO) intervention. There are limited data on the clinical implications of PMI after CTO intervention in the new-generation drug-eluting stent (DES) era. We enrolled 337 patients who underwent CTO intervention and met the study criteria. We evaluated the incidence and predictors of PMI, defined as an increase in creatine kinase-MB ≥3× the upper limit of normal (ULN) after intervention and compared the occurrence rates of major adverse cardiac and cerebrovascular events (MACCE, defined as the composite of cardiac death, myocardial infarction, stent thrombosis, target-vessel revascularization, or cerebrovascular accidents) between the PMI and non-PMI groups. PMI occurred in 23 (6.8%) patients after CTO intervention. Significant independent predictors were previous bypass surgery [odds ratio (OR) = 5.52, 95% confidence interval (CI) = 1.17-25.92; P = 0.03], Japan-CTO score ≥3 (OR = 7.06, 95%CI = 2.57-19.39; P PMI group had a significantly higher MACCE rate than the non-PMI group (23.7 vs. 5.6%, P = 0.008 by log-rank test). PMI was an independent predictor of MACCE (HR = 4.26, 95%CI = 1.35-13.43; P = 0.01). The MACCE rate gradually increased in a CK-MB-dependent fashion and was highest in patients with ≥10× ULN (P = 0.005). Previous bypass surgery, high Japan-CTO score, side branch occlusion, and longer procedure time were strongly related to PMI occurrence after CTO intervention. PMI was significantly associated with worse clinical outcomes in the new-generation DES era. © 2017 Wiley Periodicals, Inc.

    Cost-effectiveness is a major criterion underpinning decisions in mainstream health care. Acupuncture is increasingly used in patients with chronic lower back pain (LBP), but there is a lack of evidence on cost-effectiveness. The objective of this study was to assess the cost-effectiveness of acupuncture in alleviating chronic LBP either alone or in conjunction with standard care compared with patients receiving routine care, and/or sham. To determine effectiveness, we undertook meta-analyses which found a significant improvement in pain in those receiving acupuncture and standard care compared with those receiving standard care alone. For acupuncture and standard care vs. standard care and sham, a weak positive effect was found for weeks 12 to 16, but this was not significant. For acupuncture alone vs. standard care alone, a significant positive effect was found at week 8, but not at weeks 26 or 52. The main outcome parameters for our cost-effectiveness analysis were the incremental cost-effectiveness ratio (ICER) of acupuncture treatment presented as cost (A$) per disability-adjusted life-year (DALY) saved. The WHO benchmark for a very highly cost-effective intervention is one that costs less than gross domestic product per capita per quality-adjusted life-year (QALY) gained or DALY averted, or less than around $A52,000 in 2009 (the base year for the analysis). According to this threshold, acupuncture as a complement to standard care for relief of chronic LBP is highly cost-effective, costing around $48,562 per DALY avoided. When comorbid depression is alleviated at the same rate as pain, cost is around $18,960 per DALY avoided. Acupuncture as a substitute for standard care was not found to be cost-effective unless comorbid depression was included. According to the WHO cost-effectiveness threshold values, acupuncture is a cost-effective treatment strategy in patients with chronic LBP. © 2013 World Institute of Pain.

    Multifidus cross-sectional area was often measured in chronic low back pain (LBP) patients to estimate the muscle activity for spinal stability. However, such estimation may be inadequate as the contribution of muscle elasticity in muscle activity is ignored. In vivo quantitative data on multifidus elasticity is therefore important for the study of muscle contractile function in response to motor control for spinal stability in chronic LBP patients. The purpose of this study was to quantify the elasticity, cross-sectional area, and fat area of the multifidus for the contractile function and the distribution of deformable muscle tissue and nondeformable fat tissue at different postures in patients with and without chronic LBP. This is a prospective study. Force-deformation data of the multifidus were acquired using ultrasound elastography. The anatomical changes of the multifidus were measured on the cross-sectional images of the multifidus acquired using B-mode ultrasound imaging. The sample comprised 12 adult male patients with chronic LBP and 12 asymptomatic male controls. The outcome measure was the elasticity of the multifidus at the L4 level for the assessment of muscle contractile function when patients were in the prone, upright, and 25° and 45° forward stooping positions. The cross-sectional area and fat area were also measured on the B-mode ultrasound images of the multifidus acquired at the same vertebral level and the postures. With the patients in each of the prone, upright, and 25° and 45° forward stooping positions, ultrasound elastography and B-mode ultrasound imaging were performed on the left and right multifidus at the L4 level. The elasticity of multifidus indicated by the effective Young's modulus was derived from the force-deformation data acquired using ultrasound elastography. The cross-sectional area and fat area were assessed on the B-mode ultrasound images. The effective Young's modulus, cross-sectional area, and fat area were analyzed

    To explore the experiences, opinions and treatment expectations of chronic low back pain (LBP) patients in order to identify what components of treatment they consider as being of most value. Three stand-alone focus groups were convened. All participants were experiencing chronic non-specific LBP (>3 months). Each group was facilitated by an independent moderator, and guided by a series of pre-determined questions. Participants were encouraged to freely air their personal opinions during the discussion. Transcribed data were organized into a series of 'categories' using the Qualitative Solutions for Researchers Nudist 6 package from which five common themes emerged. Each participant had typically experienced a variety of failed treatment approaches. Whilst the value of advice and exercise was recognized, participants typically questioned the appropriateness of such treatment given the fact that a precise diagnosis was rarely given, and symptoms often recurred. As a result, poor adherence with advice and exercise appeared to be a key factor limiting the potential effectiveness of long-term self-management strategies. Participants considered appropriate exercise (despite pain) and activity modification as important components for effective long-term self-management of symptoms. To enhance treatment effectiveness, participants welcomed the introduction of individually tailored advice and exercise programmes, with supervision and follow-up support, along with a better understanding of the physical and emotional impact of chronic LBP by practitioners.

It’s estimated that about 70-85% of the population will suffer at least one episode of LBP during their life. The aim of present study was to compare the effects of massage and modality in patient with sub-acute and chronic non-specific LBPMethods: In this clinical trial study 30 women (MeanAge: 33.96±10.93 with sub-acute and chronic non-specific LBP (Mean pain-duration:9.68±3.38 were included in the study and randomized into two equal groups; massage and modality. Patients in both group underwent 10 sessions treatment period. Pain (numerical-pain-scale,NRS, functional disability index (oswestry-disability-index,ODI and lumbar-flexion(modified-schober-testwere recorded before and immediately after treatment period. Data was analyzed using paired t-test and independent sample t-test.Results: Significant improvement showed in both groups separately in pain-intensity, disability level, and flexion after treatment (P<0.001. Statically significant improvement was seen in massage group in comparison to modality group for NRS & ODI after treatment (PNRS=0.015, PODI=0.013. There was a not significant change in point of lumber flexion between two groupsConclusion: The results showed that both massage and modality had beneficial effects on the improvement of pain, functional disability and lumbar flexion in patients with non-specific LBP. It seems that massage is better than modality for non-specific LBP in a short period of time.

    Full Text Available Abstract Background Physical activity in leisure time is often considered to have favourable effects on the risk of low back pain (LBP, but demonstrating a definite association in epidemiological studies has proven difficult. The purpose of the present study was to explore associations between physical activity and risk of chronic LBP in an adult population and to investigate whether relationships are limited to certain age groups or to females or males. A particular objective was to determine whether support could be found for a U-shaped relationship, with both low and high activity levels carrying greater risk. Methods The relationship between physical activity and risk of chronic LBP was examined in a Norwegian prospective study using data from the community-based HUNT2 and HUNT3 surveys. Participants were 9616 women and 8452 men without LBP at baseline, who reported after 11 years whether they suffered from LBP. Associations between baseline physical activity in leisure time and risk of chronic LBP at end of follow-up were evaluated by generalized linear modelling with adjustment for potential confounders. Results Significant associations between leisure time physical activity and risk were observed in both sexes after age adjustment, mainly suggesting inverse relationships. Women participating in hard physical activity 1–2 h per week had a relative risk (RR of chronic LBP of 0.81 (95 % CI 0.71–0.93 compared to those with only light physical activity less than 1 h per week. The corresponding RR in men was 0.71 (95 % CI 0.60–0.85. After adjustment for education, employment, occupational activity, body mass index (BMI and smoking, significant relationships could only be demonstrated in those aged 50 years or more at baseline. The associations differed between female educational groups, with more U-shaped relationships being observed among women with basic education only. Conclusion No strong support was found overall for U

    Bertolotti's syndrome (BS) must be considered as a differential diagnosis in a young patient presenting with low back pain (LBP). We present a case of a 26-year-old male complaining of mild chronic LBP for six years, radiating to his left thigh for the past six months. He has been taking non-steroidal anti-inflammatory drugs (NSAIDs) with skeletal muscle relaxants for pain relief. The X-ray and computed tomography (CT) imagings showed congenital enlargement of the left transverse process of the fifth lumbar (L5) vertebra forming pseudo-articulation with the sacrum and unilateral pars interarticularis defect at the L4 level on the left side, respectively. He has managed with gabapentin 100 mg three times a day for his neuropathic left leg pain. On follow-up, the patient reported that his pain has improved with gabapentin and it decreased from 8/10 to 4/10 on the visual analogue scale.

    The objective of this study was the measure the onset time of the transverse abdominis (TA) muscle during rapid unilateral shoulder movements in individuals with chronic low back pain (LBP), and to evaluate the relationship between latency times and self-report measures of pain and disability. Descriptive cross-sectional study. University laboratory. Eighty individuals with chronic LBP of a non-specific origin (males n=44, females n=36). Responses of the right and left surface TA/internal obliques were measured using surface electromyography (EMG) during rapid unilateral shoulder flexion, abduction, and extension. Pain intensity was measured using a visual analog scale (VAS), and disability with the Oswestry disability index (ODI). Seventy-five percent of individuals were identified as lacking feedforward activation. A significant sidexdirection main effect was identified, with the ipsilateral latency more delayed in flexion and abduction (F(2316)=58.2, plower ODI scores (23.2+/-6.9% vs 31.0+/-9.2%, mean difference 7.8%, 95% CI 3.9 to 11.6%, pmuscle onsets during rapid limb movement were significantly associated with self-rated pain scores. Seventy-five percent of individuals with chronic non-specific LBP exhibited delayed activation.

    Full Text Available BACKGROUND: Pain in the lower region of the back and pelvis – also called "Low Back Pain" (LBP - is very frequent during pregnancy. According to many authors it is a major complaint of more than half of all pregnant women; it causes mental and physical discomfort. The etiology of LBP during pregnancy is still not fully known. OBJECTIVE: The main aim of our research was to objectify the relationship between the presence of LBP, the training level of the postural muscles and the degree of the pelvic inclination of women in the third trimester of pregnancy. That is why the relationship between pelvic inclination and LBP occurrence is compared within the context of two groups – reasonable physically active as compared to physically inactive women. METHODS: Twenty-seven pregnant probands aged 20 – 35 years and in the second half of their third trimester were included in the experiment. All of them complained of pain in their lumbar spine and in the pelvicarea. They were divided into two groups: 14 physically inactive women and 13 physically active women, who have been performing physical activity for at least 135 minutes per week for at least 1 year before conception and for at least 90 minutes per week during pregnancy. The exercises were focused on the functioning of the postural system, e.g. yoga, Pilatespilatek and exercises by Mojzisova. We measured the inclination of the pelvis (using non-invasive anthropometric measuring and observed the presence of pain in the selected area: clinically via the Patrick-Faber test and posterior pelvic pain provocation test and subjectively with the aid of a standardized LBP related survey. The statistical methods used were the t-test, the median and Wilcoxon-White test and the Spearman factor of serial correlations. RESULTS: We observed a statistically significant difference between the pelvic inclination of physically active and inactive women (using a t-test for non-pair values with a significance level

    Mindfulness is a nonpharmacologic mind-body therapy that has been shown to be effective in older adults with chronic low back pain (cLBP). There are few first-person accounts in the literature that describe the older adult experience and perspective while learning mindfulness and meditation to treat pain. The objective of this study was to investigate dominant themes present in the experiences of older adults applying mindfulness and meditation to cope with cLBP. Qualitative analysis of four focus groups. Twenty-five adults age 65 years or older who had completed an eight-week mindfulness program. The focus groups met for a comprehensive discussion session about their experience with mindfulness and meditation. The audio for each session was recorded, and the discussions were transcribed. Codebook development, qualitative coding, and thematic analysis were performed. The coders each coded all four transcripts, following which they met to adjudicate all coding differences until they were in complete agreement on coding. Several key themes were brought up by older adults utilizing mindfulness as a means of coping with pain, which included overcoming fear of pain ("Before [learning mindfulness], I used to dread pain"), pain awareness ("You're focusing more on being aware than the pain; now that's what helps me"), and pain significance ("It becomes insignificant"). The themes identify several ways mindfulness impacts older adults with cLBP, including decreased negative emotions related to chronic pain such as fear of pain, a different perspective or change in awareness about pain, and reducing the significance of pain. © 2017 American Academy of Pain Medicine.

    Chronic pancreatitis is an ongoing inflammatory process that may over time lead to mal digestion, malabsorption and diabetic syndrome. Identification of risk (etiological) factors based on classifications TIGAR-O or later M-ANNHEIM. These factors (environmental and / or genetic) leads to failure of the stability of the digestive and lysosomal enzymes in the acinar cells, resulting in premature activation of digestive enzymes in the pancreas, and repeated nekroinflamation and fibrosis. The incidence has of the upward trend. Clinically the disease manifests itself in most cases with pain and possibly with nonspecific dyspeptic troubles. Decisive role in the diagnosis playing imaging methods, trans abdominal ultrasonography, computed tomography, magnetic resonance imaging, magnetic cholangiopancretography and foremost endoscopic ultrasonography, which has the highest sensitivity and specificity. Endoscopic retrograde cholangiopancreatography is currently regarded as a method for therapy, not for diagnosis. Less importance is now attached to a functional test. Symptomatic treatment is usually conservative. Abstinence is necessary, easily digestible, but calorie-rich diet with reduced fat. Most patients needed treatment with analgesics. In case of insufficient effect of analgesics is necessary to consider endoscopic therapy or surgery. If the external secretory insufficiency is present are served pancreatic extracts. Diabetic syndrome requires insulin delivery. Generally, chronic pancreatitis is a disease treatable but incurable. Proportion of patients are also dying of pancreatic cancer. (author)

    The impairment in musculoskeletal structures in patients with low back pain (LBP) is often disproportionate to their complaint. Therefore, the need arises for exploration of alternative mechanisms contributing to the origin and maintenance of non-specific LBP. The recent focus has been on central nervous system phenomena in LBP and the pathophysiological mechanisms underlying the various symptoms and characteristics of chronic pain. Knowledge concerning changes in pain processing in LBP remains ambiguous, partly due to the diversity in the LBP population. The purpose of this study is to compare quantitative sensory assessment in different groups of LBP patients with regard to chronicity. Recurrent low back pain (RLBP), mild chronic low back pain (CLBP), and severe CLBP are compared on the one hand with healthy controls (HC), and on the other hand with fibromyalgia (FM) patients, in which abnormal pain processing has previously been reported. Cross-sectional study. Department of Rehabilitation Sciences, Ghent University, Belgium. Twenty-three RLBP, 15 mild CLBP, 16 severe CLBP, 26 FM, and 21 HC participated in this study. Quantitative sensory testing was conducted by manual pressure algometry and computer-controlled cuff algometry. A manual algometer was used to evaluate hyperalgesia as well as temporal summation of pain and a cuff algometer was used to evaluate deep tissue hyperalgesia, the efficacy of the conditioned pain modulation and spatial summation of pain. Pressure pain thresholds by manual algometry were significantly lower in FM compared to HC, RLBP, and severe CLBP. Temporal summation of pain was significantly higher in FM compared to HC and RLBP. Pain tolerance thresholds assessed by cuff algometry were significantly lower in FM compared to HC and RLBP and also in severe CLBP compared to RLBP. No significant differences between groups were found for spatial summation or conditioned pain modulation. No psychosocial issues were taken into account for this

    Evidence to support the use of bone hydroxydiphosphonate (HDP) single photon emission computed tomography (SPECT/CT) in patients with facetogenic low back pain (LBP) is still limited. In this study we compared the scintigraphic patterns on bone SPECT/CT with the degree of structural facet joint (FJ) degeneration on CT in patients with LBP. Ninety-nine consecutive patients with LBP were prospectively evaluated. Patients with known or suspected malignancy, trauma, infectious processes, chronic inflammatory diseases, and previous surgery were excluded. The effect of LBP on the daily quality of life was assessed with the Oswestry disability index (ODI). The Pathria grading system was used to score FJ degeneration on CT scans. The correlation between the degree of FJ degeneration and osteoblastic activity on SPECT/CT was analyzed with Kappa statistics. Ninety-nine patients were included (59 female, mean age 56.2 years). The mean ODI score was 38.5% (range, 8% to 72%). In all, 792 FJ (L2-3 to L5-S1) were examined. Of the FJs, 49.6% were Pathria grade 0-1 (normal to mild degeneration) on CT, 35% were grade 2 (moderate degeneration), and 16% were grade 3 (severe degeneration). Sixty-seven percent of the patients had scintigraphically active FJs on SPECT/CT. Sixty-nine percent of Pathria grade 3 FJs were scintigraphically active; 5.5% and 16.8% of Pathria grade 0-1 and Pathria grade 2, respectively, were active. Of the metabolically active FJs, 71.4% were at the L4-5/L5-S1 levels. The ability of SPECT/CT to precisely localize scintigraphically active FJs may provide significant improvement in the diagnosis and treatment of patients with LBP. In this study we demonstrate that in >40% of FJs, the scintigraphic patterns on SPECT/CT did not correlate with the degree of degeneration on CT. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Chronic low back pain (LBP is a major public and occupational health problem, which is associated with very high costs. Although medical costs for chronic LBP are high, most costs are related to productivity losses due to sick leave. In general, the prognosis for return to work (RTW is good but a minority of patients will be absent long-term from work. Research shows that work related problems are associated with an increase in seeking medical care and sick leave. Usual medical care of patients is however, not specifically aimed at RTW. The objective is to present the design of a randomized controlled trial, i.e. the BRIDGE-study, evaluating the effectiveness in improving RTW and cost-effectiveness of a multidisciplinary outpatient care program situated in both primary and outpatient care setting compared with usual clinical medical care for patients with chronic LBP. Methods/Design The design is a randomized controlled trial with an economic evaluation alongside. The study population consists of patients with chronic LBP who are completely or partially sick listed and visit an outpatient clinic of one of the participating hospitals in Amsterdam (the Netherlands. Two interventions will be compared. 1. a multidisciplinary outpatient care program consisting of a workplace intervention based on participatory ergonomics, and a graded activity program using cognitive behavioural principles. 2. usual care provided by the medical specialist, the occupational physician, the patient's general practitioner and allied health professionals. The primary outcome measure is sick leave duration until full RTW. Sick leave duration is measured monthly by self-report during one year. Data on sick leave during one-year follow-up are also requested form the employers.

    Full Text Available Abstract Background Low back pain (LBP is a major health problem in modern society, with 70-85% of the population experiencing LBP at some time in their lives. Each year, 5-10% of the workforce misses work due to LBP, most for less than 7 days. Almost 10% of all patients are at risk of developing chronic pain and disability. Little clinical evidence is available for the majority of treatments used in LBP therapy. However, moderate evidence exists for interdisciplinary rehabilitation, exercise, acupuncture, spinal manipulation, and cognitive behavioral therapy for subacute and chronic LBP. The SMATH® system (system for automatic thermomechanic massage in health is a new medical device (MD that combines basic principles of mechanical massage, thermotherapy, acupressure, infrared therapy, and moxibustion. SMATH® is suitable for automatic multidisciplinary treatment on patients with non-specific sub-acute and chronic LBP. Methods/design This paper describes the protocol for a double-blinded, sham-controlled, randomized, single-center short term clinical trial in patients with non-specific sub-acute and chronic LBP aged 18 to 70 years. The primary outcome will be the effectiveness of SMATH® versus sham therapy (medical device without active principles determined by evaluating self perceived physical function with Roland Morris Disability Questionnaire (RMDQ scores after 4 weeks of treatment (end of treatment. Major secondary outcome will be effectiveness of SMATH® determined by evaluating self perceived physical function comparing RMDQ scores between end of treatment and baseline.

    Full Text Available Any link between pancreatic carcinoma and chronic pancreatitis could reflect the malignant potential of a chronic inflammatory process. Four patients with ductal adenocarcinomas had a long history of pancreatic pain (median duration 5 years and showed clearcut evidence of chronic pancreatitis “downstream” of the tumour. Four were alcoholics and two heavy smokers. These four cases arose within a surgical series of approximately 250 patients with chronic pancreatitis, giving an incidence of 1.6 per cent. The incidence and anatomical distribution of carcinoma and chronic pancreatitis could possibly be consistent with a casual relationship.

    Physical deconditioning in combination with societal and emotional factors has been hypothesized to compromise complete recovery from low back pain (LBP). However, there is a lack of longitudinal studies designed to specifically investigate physical activity as an independent prognostic factor. We conducted a prognostic study to investigate whether levels of leisure time physical activity are independently associated with clinical outcomes in people seeking care for chronic and persistent LBP. A total of 815 consecutive patients presenting with LBP to an outpatient spine centre in secondary care were recruited. Separate multivariate linear regression analyses were performed to investigate whether levels of leisure time physical activity (i.e., sedentary, light and moderate-to-vigorous leisure time physical activity levels) predict pain and disability at 12-month follow-up, after adjusting for age, pain, episode duration, disability, neurological symptoms, depression and fear of movement. Final models showed evidence of an association between baseline physical activity and 12-month outcomes (p physical activity group reported less pain and disability compared with the sedentary group. Our findings suggest that physical activity levels may have a role in the prognosis of LBP. Specific domains of physical activity warrant further investigation to better understand this association. © 2014 European Pain Federation - EFIC®

    An alternative approach to facilitate movement and control through the trunk and pelvis is belly dancing. Investigations of belly dancing mechanics indicate similar muscular activation patterns of those known to influence chronic low back pain (cLBP). However, no documented studies have examined its effectiveness as a treatment for cLBP. The purpose of this study was to investigate the influence of a standardized belly dance program in women with cLBP. A single subject design was used to evaluate weekly outcomes during a three-week baseline period, six-week belly dance program, and again at a two-month follow-up. Outcome measures for pain, disability, function, and fear-avoidance beliefs were utilized. Two subjects completed the program. No significant differences were noted during the baseline assessment period. At two months, subject one demonstrated change scores of -1.12, -1%, and 2.2 for pain, disability, and function respectively while subject two demonstrated change scores of 5.4, 5%, and 1.1 for pain, disability, and function, respectively. Subject one showed a clinically significant change score for both fear avoidance of work and physical activity, with score changes of 4 and 3.3, respectively. The results of this study suggest a standardized belly dance program may positively influence pain and function in women with cLBP.

    The aim of the present study was to compare three different forms of exercises namely lumbar stabilization, dynamic strengthening, and Pilates on chronic low back pain (LBP) in terms of pain, range of motion, core strength and function. In this study, 44 subjects suffering from non-specific LBP for more than 3 months were randomly allocated into the lumbar stabilization group, the dynamic strengthening group, and the Pilates group. Ten sessions of exercises for 3 weeks were prescribed along with interferential current and hot moist pack. Pain was assessed by visual analog scale, functional affection by modified Oswestry Disability Questionnaire, range of motion by assessing lumbar flexion and extension by modified Schober test and core strength was assessed by pressure biofeedback on day 1 and day 10 of the treatment. There was reduction of pain, improvement in range of motion, functional ability and core strength in all the 3 exercise groups. The improvement was significantly greater in the lumbar stabilization group for all the outcome measures, when compared the posttreatment after 10th session. Pairwise comparison showed that there was greater reduction of disability in the Pilates group than the dynamic strengthening group. It was concluded that the lumbar stabilization is more superior compared to the dynamic strengthening and Pilates in chronic nonspecific LBP. However, long-term benefits need to be assessed and compared with prospective follow-up studies.

    Full Text Available Background The trunk muscles are vital for the maintenance of spinal stability. Training of specific muscles surrounding the lumbar spine, which provide dynamic and segmental stability, is one of the major goals in the management of patients with chronic low back pain (LBP. However, more investigation of lumbar stabilization training using a ball is required before making any strong conclusions about its efficacy. Objectives The aim of this study was to compare the effect of trunk stabilization exercises and conventional back care exercises for patients with chronic LBP. Patients and Methods Thirty male subjects with chronic LBP were randomly assigned to two groups. The experimental group received trunk stabilization exercise using a gym ball whereas the control group received conventional back care exercises for six weeks. The abdominal muscle endurance, pain intensity, and functional disability were measured using pressure biofeedback, visual analogue scale (VAS, and modified Oswestry disability questionnaire (MODQ, respectively. All the measurements were taken at baseline and during week two, four and six. Results The results of the study demonstrated significant improvements in abdominal muscle endurance and reduction in VAS and MODQ score of both groups (P = 0.001. The trunk stabilization exercise group showed greater gains in abdominal muscle endurance during weeks two to six compared to the conventional back care exercise group (P < 0.05. In addition, the trunk stabilization exercise group showed greater reduction in the VAS score (P = 0.035 and MODQ score (P = 0.001 at week six compared to the conventional back care exercise group. Conclusions The trunk stabilization exercises are more effective than conventional back care exercises in the rehabilitation of patients with chronic LBP.

    For the treatment of chronic low back pain (cLBP), both core stability and mobilization exercises were introduced. The aim of this prospective randomized clinical pilot study was to compare the efficacy of mobilization and core stability exercises with regard to objective and subjective outcome measures in patients with cLBP. After a per-protocol analysis, the data of 27 patients with cLBP, who were randomly allocated to one of the two groups, were analyzed. The intervention group (GM) performed mobilization exercises using the BALLance-Methode®, the control group (GS) carried out core stability exercises for 4 weeks, and continued the exercises for an additional 4 weeks at home. Flexibility, strength endurance of the core stabilizing muscles, pain-induced disability, and pain avoidance behavior were the objective and subjective outcomes that were measured before, 4 weeks after, and 8 weeks after the onset of the intervention. The significance of differences within and between groups was analyzed. During the observation period, only in the GS patients could maintain the prone-plank position and the side-plank position improvements over time (p core stability exercises.

    The authors performed a retrospective study to determine the incidences and range of spontaneous pathology findings in the lymphoid and haemopoietic systems of control Charles River CD-1 mice (Crl: CD-1(ICR) BR). Data was collected from 2,560 mice from control dose groups (104-week and 80-week carcinogenicity studies; 13-week studies), from regulatory studies evaluated at the authors' laboratory between 2005 and 2010. Lesions of the lymphoid and hematopoietic systems were uncommon in 13-week studies but were of high incidence in the carcinogenicity studies (80- or 104-week duration). The most common finding overall was lymphoid hyperplasia within the spleen, thymus, and lymph nodes. The finding of benign lymphoid hyperplasia of the thymus is unusual in other mouse strains. The most common cause of death in the carcinogenicity studies was lymphoma. It is hoped that the results presented here will provide a useful database of incidental pathology findings in CD-1 mice on carcinogenicity studies.

    To identify relative provider costs, clinical outcomes, and patient satisfaction for the treatment of low back pain (LBP). This was a practice-based, nonrandomized, comparative study of patients self-referring to 60 doctors of chiropractic and 111 medical doctors in 51 chiropractic and 14 general practice community clinics over a 2-year period. Patients were included if they were at least 18 years old, ambulatory, and had low back pain of mechanical origin (n = 2780). Outcomes were (standardized) office costs, office costs plus referral costs for office-based care and advanced imaging, pain, functional disability, patient satisfaction, physical health, and mental health evaluated at 3 and 12 months after the start of care. Multiple regression analysis was used to correct for baseline differences between provider types. Chiropractic office costs were higher for both acute and chronic patients (P .20). Acute and chronic chiropractic patients experienced better outcomes in pain, functional disability, and patient satisfaction (P pain and disability improvement were found for chronic patients only. Chiropractic care appeared relatively cost-effective for the treatment of chronic LBP. Chiropractic and medical care performed comparably for acute patients. Practice-based clinical outcomes were consistent with systematic reviews of spinal manipulation efficacy: manipulation-based therapy is at least as good as and, in some cases, better than other therapeusis. This evidence can guide physicians, payers, and policy makers in evaluating chiropractic as a treatment option for low back pain.

    Study Objectives: Insomnia, which is very common in patients with chronic low back pain (LBP), has long been viewed as a pain symptom that did not merit specific treatment. Recent data suggest that adding insomnia therapy to pain-targeted treatment should improve outcome; however, this has not been empirically tested in LBP or in any pain condition treated with a standardized pain medication regimen. We sought to test the hypothesis that adding insomnia therapy to pain-targeted treatment might improve sleep and pain in LBP. Design: Double-blind, placebo-controlled, parallel-group, 1-mo trial. Setting: Duke University Medical Center Outpatient Sleep Clinic. Patients: Fifty-two adult volunteers with LBP of at least 3 mo duration who met diagnostic criteria for insomnia (mean age: 42.5 y; 63% females). Interventions: Subjects were randomized to eszopiclone (ESZ) 3 mg plus naproxen 500 mg BID or matching placebo plus naproxen 500 mg twice a day. Measurements and Results: ESZ significantly improved total sleep time (mean increase: ESZ, 95 min; placebo, 9 min) (primary outcome) and nearly all sleep measures as well as visual analog scale pain (mean decrease: ESZ, 17 mm; placebo, 2 mm) (primary pain outcome), and depression (mean Hamilton Depression Rating Scale improvement ESZ, 3.8; placebo, 0.4) compared with placebo. Changes in pain ratings were significantly correlated with changes in sleep. Conclusions: The addition of insomnia-specific therapy to a standardized naproxen pain regimen significantly improves sleep, pain, and depression in patients with chronic low back pain (LBP). The findings indicate the importance of administering both sleep and pain-directed therapies to patients with LBP in clinical practice and provide strong evidence that improving sleep disturbance may improve pain.

    Low back pain (LBP) is one of the largest and most frequent public health problems worldwide. Photobiomodulation therapy (PBMT) is a frequently used non-pharmacological therapy for the treatment of musculoskeletal disorders. However, there is little high-quality scientific evidence that demonstrates the effectiveness of PBMT in the treatment of patients with chronic LBP in the short, medium and long term. Therefore, the objective of this clinical trial is to evaluate the effects of PBMT in patients with chronic non-specific LBP in the short, medium and long term. This is a prospectively registered, two-arm randomised placebo-controlled trial with blinded patients, assessors and treatment providers. One hundred and forty-eight patients with chronic non-specific LBP will be recruited. Treatment sessions will be provided three times a week for 4 weeks (totaling 12 sessions) with patients receiving either placebo or active PBMT. For ethical reasons, all patients, regardless of treatment allocation, will also receive an information booklet based on 'The Back Book'. Clinical outcomes will be measured at baseline, at the end of treatment, as well as 3, 6 and 12 months after randomisation. The primary outcomes will be pain intensity and disability measured after 12 sessions of treatment. The secondary outcomes will be pain intensity and disability measured at 3, 6 and 12 months after randomisation, in addition to specific disability and global perceived effect in all time points. The study was approved by the Research Ethics Committee of Universidade Cidade de São Paulo. The results will be disseminated through scientific publications and presentations at national and international scientific meetings.

    Chronic low back pain (LBP) is a major cause of disability; early diagnosis and stratification of care remain challenges. This article describes the development of a screening tool for the 1-year prognosis of patients with high chronic LBP risk (risk stratification index) and for treatment allocation according to treatment-modifiable yellow flag indicators (risk prevention indices, RPI-S). Screening tools were derived from a multicentre longitudinal study (n = 1071, age >18, intermittent LBP). The greatest prognostic predictors of 4 flag domains ("pain," "distress," "social-environment," "medical care-environment") were determined using least absolute shrinkage and selection operator regression analysis. Internal validity and prognosis error were evaluated after 1-year follow-up. Receiver operating characteristic curves for discrimination (area under the curve) and cutoff values were determined. The risk stratification index identified persons with increased risk of chronic LBP and accurately estimated expected pain intensity and disability on the Pain Grade Questionnaire (0-100 points) up to 1 year later with an average prognosis error of 15 points. In addition, 3-risk classes were discerned with an accuracy of area under the curve = 0.74 (95% confidence interval 0.63-0.85). The RPI-S also distinguished persons with potentially modifiable prognostic indicators from 4 flag domains and stratified allocation to biopsychosocial treatments accordingly. The screening tools, developed in compliance with the PROGRESS and TRIPOD statements, revealed good validation and prognostic strength. These tools improve on existing screening tools because of their utility for secondary preventions, incorporation of exercise effect modifiers, exact pain estimations, and personalized allocation to multimodal treatments.

    Low back pain (LBP) is a major cause of disability throughout the world. However, longitudinal evidence to relate low back pain and functional limitations is mostly confined to Western countries. In this study, we investigate the associations between low back pain and functional limitations in a prospective cohort of Thai adults. We analysed information from the Thai Cohort Study of adult Open University adults which included 42,785 participants in both 2009 and 2013, with the majority aged 30 to 65 years and residing nationwide. We used multivariate logistic regression to explore the longitudinal associations between LBP in 2009 and 2013 ('never': no LBP in 2009 or 2013; 'reverting': LBP in 2009 but not in 2013; 'incident': no LBP in 2009 but LBP in 2013; and 'chronic': reporting LBP at both time points) and the outcome of functional limitations relating to Activities of Daily Living (ADL) in 2013. Low back pain was common with 30% of cohort members reporting low back pain in both 2009 and 2013 ('chronic LBP'). The 'chronic LBP' group was more likely than the 'never' back pain group to report functional limitations in 2013: adjusted odds ratios 1.60 [95% Confidence Interval: 1.38-1.85] for difficulties getting dressed; 1.98 [1.71-2.30] for walking; 2.02 [1.71-2.39] for climbing stairs; and 3.80 [3.38-4.27] for bending/kneeling. Those with 'incident LBP' or 'reverting LBP' both had increased odds of functional limitations in 2013 but the odds were not generally as high. Our nationwide data from Thailand suggests that LBP is a frequent public health problem among economically productive age groups with adverse effects on the activities of daily living. This study adds to the limited longitudinal evidence on the substantial impact of low back pain in Southeast Asia.

    In many countries a reporting system of radiological incidents to national regulatory body exists and providers of radiotherapy treatment are obliged to report all major and/or in some countries all incidents occurring in institution. State Office for Nuclear Safety (SONS) is providing a systematic guidance for radiotherapy departments from 1997 by requiring inclusion of radiation safety problems into Quality assurance manual, which is the basic document for obtaining a license of SONS for handling with sources of ionizing radiation. For that purpose SONS also issued the recommendation 'Introduction of QA system for important sources in radiotherapy-radiological incidents' in which the radiological incidents are defined and the basic guidance for their classification (category A, B, C, D), investigation and reporting are given. At regular periods the SONS in co-operation with radiotherapy centers is making a survey of all radiological incidents occurring in institutions and it is presenting obtained information in synoptic communication (2003 Motolske dny, 2005 Novy Jicin). This presentation is another summary report of radiological incidents that occurred in our radiotherapy institutions during last 3 years. Emphasis is given not only to survey and statistics, but also to analysis of reasons of the radiological incidents and to their detection and prevention. Analyses of incidents in radiotherapy have led to a much broader understanding of incident causation. Information about the error should be shared as early as possible during or after investigation by all radiotherapy centers. Learning from incidents, errors and near misses should be a part of improvement of the QA system in institutions. Generally, it is recommended that all radiotherapy facilities should participate in the reporting, analyzing and learning system to facilitate the dissemination of knowledge throughout the whole country to prevent errors in radiotherapy.(authors)

    Acute low back pain (LBP) is the fifth most common reason for physician visits and about nine out of ten adults experience back pain at some point in their life. In a large number of patients LBP is associated with disc herniation (DH). Recently, oxygen-ozone (O2O3) therapy has been used successfully in the treatment of LBP, reducing pain after the failure of other conservative treatments. The aim of this study was to assess the effects of O2O3 therapy in back pain rehabilitation, comparing three groups of patients suffering from chronic back pain associated with DH submitted to three different treatments: intramuscular O2O3 infiltrations, global postural An observational retrospective/horizontal study to compare oxygen-ozone therapy and/or global postural re-education in complicated chronic low back pain re-education (GPR), or a combination of the two (O2O3+GPR). The data show that pain severity before treatment was significantly lower in the patients treated with GPR alone (VAS score 7.4) than in the O2O3+GPR patients (VAS score 8.5) and the O2O3 patients (VAS score 8.6). At the end of treatment, pain severity was lower in the O2O3 patients than in the GPR-alone patients. After some years of follow-up only the difference between O2O3+GPR and GPR-alone remained significant.

    Chronic low back pain (LBP) can be managed by exercises which should be tailored to an individual's readiness to behavioral change. To evaluate the effects of an intervention program based on the Transtheoretical Model of behavioral change (TTM) on back muscle endurance, physical function and pain in rice farmers with chronic LBP. In a 32-week study, 126 rice farmers were allocated to the TTM (n= 62) and non-TTM (n= 64) groups. Modified Biering-Sorensen test, Oswestry Disability Questionnaire and visual analogue scale were used for evaluating back muscle endurance, physical function and severity of pain, respectively. The evaluations were performed at baseline and at weeks 8, 20 and 32 of the study. Data were analyzed using repeated measure ANOVA. The back muscle endurance was significantly greater in the TTM group than in the non-TTM group at week 32 (p= 0.025). Physical function and severity of pain were significantly improved in the TTM group when compared with the non-TTM group at weeks 20 and 32 (pfarmers with LBP. Further studies should be considered to explore the long-term effects of this intervention.

Endotoxin core antibodies (EndoCAb, LPS binding protein (LBP and soluble CD14 (sCD14 act as modulators of LPS induced activation of innate immune system in vivo. For the present study we estimated the levels of LPS and its translocation markers in T1DM subjects with and without microvascular complications (MVC and correlate them with clinical parameters of T1DM and serum inflammatory cytokine levels (TNF-α, IL-6, IL-1β and GM-CSF.A total of 197 subjects (64 normal glucose tolerance (NGT subjects, 97 T1DM subjects without MVC and 36 with MVC were included in this study and the levels of serum LPS, its translocation markers and cytokines measured by immunoassays.Compared to NGT, T1DM subjects (both with and without MVC had significantly higher levels of LPS, reduced levels of LBP and EndoCAb along with significant increase in the levels of IL-1β, IL-6, TNF-α and GM-CSF (p<0.05. No significant change was seen in the levels of these biomarkers between T1DM subjects with and without MVC.Decreased levels of EndoCAb and LBP suggest sustained endotoxin activity in T1DM subjects even before the onset of microvascular complications.

    Greenland remains a highly endemic area for hepatitis B virus (HBV) infection. This is in sharp contrast to other modern societies, such as Denmark. To address this discrepancy, we investigated the natural history of HBV infection in Greenland by estimating the age-specific incidence of HBV...... infection, the proportion of chronic carriers, and the rates of hepatitis B surface antigen seroclearance. In total, 8,879 Greenlanders (16% of the population) from population-based surveys conducted in 1987 and 1998 were followed through March 2010. Data on HBV status were supplemented by HBV test results...... from all available HBV registries in Greenland to determine changes in HBV status over time. Incidence rates of HBV infection and hepatitis B surface antigen seroclearance were estimated after taking into account interval censoring.

    Full Text Available Abstract Background While there is growing evidence for the efficacy of SM to treat LBP, little is known on the mechanisms and physiologic effects of these treatments. Accordingly, the purpose of this study was to determine whether SM alters the amplitude of the motor evoked potential (MEP or the short-latency stretch reflex of the erector spinae muscles, and whether these physiologic responses depend on whether SM causes an audible joint sound. Methods We used transcranial magnetic stimulation to elicit MEPs and electromechanical tapping to elicit short-latency stretch reflexes in 10 patients with chronic LBP and 10 asymptomatic controls. Neurophysiologic outcomes were measured before and after SM. Changes in MEP and stretch reflex amplitude were examined based on patient grouping (LBP vs. controls, and whether SM caused an audible joint sound. Results SM did not alter the erector spinae MEP amplitude in patients with LBP (0.80 ± 0.33 vs. 0.80 ± 0.30 μV or in asymptomatic controls (0.56 ± 0.09 vs. 0.57 ± 0.06 μV. Similarly, SM did not alter the erector spinae stretch reflex amplitude in patients with LBP (0.66 ± 0.12 vs. 0.66 ± 0.15 μV or in asymptomatic controls (0.60 ± 0.09 vs. 0.55 ± 0.08 μV. Interestingly, study participants exhibiting an audible response exhibited a 20% decrease in the stretch reflex (p Conclusions These findings suggest that a single SM treatment does not systematically alter corticospinal or stretch reflex excitability of the erector spinae muscles (when assessed ~ 10-minutes following SM; however, they do indicate that the stretch reflex is attenuated when SM causes an audible response. This finding provides insight into the mechanisms of SM, and suggests that SM that produces an audible response may mechanistically act to decrease the sensitivity of the muscle spindles and/or the various segmental sites of the Ia reflex pathway.

    Background It has been suggested that low back pain (LBP) is a condition with an unpredictable pattern of exacerbation, remission, and recurrence. However, there is an incomplete understanding of the course of LBP and the determinants of the course. Objective The purposes of this study were: (1) to identify clusters of LBP patients with similar fluctuating pain patterns over time and (2) to investigate whether demographic and clinical characteristics can distinguish these clusters. Design This study was a secondary analysis of data extracted from a randomized controlled trial. Methods Pain scores were collected from 155 participants with chronic nonspecific LBP. Pain intensity was measured monthly over a 1-year period by mobile phone short message service. Cluster analysis was used to identify participants with similar fluctuating patterns of pain based on the pain measures collected over a year, and t tests were used to evaluate if the clusters differed in terms of baseline characteristics. Results The cluster analysis revealed the presence of 3 main clusters. Pain was of fluctuating nature within 2 of the clusters. Out of the 155 participants, 21 (13.5%) had fluctuating pain. Baseline disability (measured with the Roland-Morris Disability Questionnaire) and treatment groups (from the initial randomized controlled trial) were significantly different in the clusters of patients with fluctuating pain when compared with the cluster of patients without fluctuating pain. Limitations A limitation of this study was the fact that participants were undergoing treatment that may have been responsible for the rather positive prognosis observed. Conclusions A small number of patients with fluctuating patterns of pain over time were identified. This number could increase if individuals with episodic pain are included in this fluctuating group. PMID:24072729

    A systematic review and network meta-analysis. To determine current treatment options of chronic low back pain (LBP) as defined by randomized controlled trials (RCTs) and to compare effectiveness of those treatments using a mixed-treatment comparison (MTC). It is important to provide an evidence-based assessment of the treatment options that exist for LBP. A systematic search of RCTs was conducted in MEDLINE and the Cochrane Collaboration Library from 1990 to 2014. From the selected studies, we extracted preoperative and postoperative ODI and VAS back pain scores, additional surgeries, and complications. Standard and network meta-analytic techniques were used. Twelve RCTs were included in the analysis: 5 total disk replacement (TDR) versus fusion; 1 TDR versus exercise and cognitive behavioral therapy (CBT); 5 fusion versus exercise and CBT; and 1 fusion versus physical therapy (PT). On the basis of MTC, with respect to ODI change scores, the pooled mean difference favoring fusion over exercise and CBT was 2.0 points (95% CI, -1.2 to 4.8). The pooled mean difference favoring TDR over exercise and CBT was 6.4 points (95% CI, 3.2-9.3). The pooled mean difference favoring fusion over PT was 8.8 points (95% CI, 4.1-13.6). The pooled mean differences favoring TDR over fusion was 4.4 points (95% CI, 2.37-6.63). For PT versus structured exercise with CBT, the pooled mean difference favoring exercise with CBT over PT was 6.8 points (95% CI, 1.5-12.8). For TDR versus PT, the pooled mean difference favoring TDR over PT was 13.2 points (95% CI, 8.0-18.4). Additional surgery rates were similar between treatment options. All 4 treatments provided some benefit to patients with chronic LBP. According to the MTC analysis, TDR may be the most effective treatment and PT the least effective treatment for chronic LBP. This review is based on a limited number of RCT studies and does not support any 1 treatment modality for all patients.

    Activity of deep abdominal muscles increases the lumbar stability. Majority of previous studies indicated abdominal muscle activity dysfunction during static activity in patients with low back pain (LBP). However, the number of studies that evaluated deep abdominal muscle activity in dynamic standing activities in patients is limited, while this assessment provides better understanding of pain behavior during these activities. Investigation of superficial and deep abdominal muscles activity in participants with chronic LBP as compared to healthy individuals during standing tasks. Case control study. Ultrasound imaging was used to measure the thickness of transverse abdominis (TrA), internal oblique (IO) and external oblique (EO) muscles in female participants with (N = 45) and without chronic LBP (CLBP) (N = 45) during tests. The Biodex Balance System was used to provide standing tasks. The thickness of each muscle in a standing task was normalized to actual thickness at rest in the supine lying position to estimate its activity. The results indicate increases in thickness of all muscles in both groups during dynamic as compared to static standing tasks (P  0.5). Lower percentages of thickness change for TrA muscle and higher for EO muscle were found in the patients as compared to healthy individuals during all tests (P  1.28). Higher activity of superficial than deep abdominal muscles in patients as compared to healthy individuals during standing tasks indicates motor control dysfunction in patients with CLBP. Standing tasks can discriminate the individuals with and without LBP and can be progressively used in training. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Recent studies have indicated implementation of the CISM Program has impacted and reduced the cost of workers' compensation claims for stress related conditions and the number of lost work days (Ott, 1997; Western Management Consultants, 1996). Occupational health professionals need to be ready to develop and implement a comprehensive critical incident stress management process in anticipation of a major event. The ability to organize, lead, or administer critical incident stress debriefings for affected employees is a key role for the occupational health professional. Familiarity with these concepts and the ability to identify a critical incident enhances value to the business by mitigating the stress and impact to the workplace. Critical Incident Stress Management Systems have the potential for decreasing stress and restoring employees to normal life function--a win/win situation for both the employees and the organization.

    Multicenter, assessor-blind, randomized, clinical trial. To compare the effectiveness of rocker sole footwear to traditional flat sole footwear as part of the management for people with low back pain (LBP). During the past decade, persistent advertising has claimed that footwear constructed with a rocker sole will reduce LBP. However, there is no robust evidence to support these claims. One hundred fifteen people with chronic LBP were randomized to wear rocker sole shoes or flat sole shoes for a minimum of 2 hours each day while standing and walking. Primary outcome was the Roland Morris Disability Questionnaire (RMDQ). In addition, participants attended an exercise and education program once a week for 4 weeks and wore their assigned shoes during these sessions. Participants were assessed without their knowledge of group allocation prerandomization, and at 6 weeks, 6 months, and 1 year (main outcome point). Analysis was by intention-to-treat method. At 12 months, data from 44 of 58 (77.2%) of the rocker sole group and 49 of 57 (84.5%) of the flat sole group were available for analysis. In the rocker sole group, mean reduction in RMDQ was -3.1 (95% CI [confidence interval], -4.5 to -1.6), and in the flat sole group, it was -4.4 (95% CI, -5.8 to -3.1) (a greater negative value represents a greater reduction in disability). At 6 months, more people wearing flat shoes compared with those wearing rocker shoes demonstrated a minimal clinically important improvement in disability (53.2% and 31.1%, respectively; P = 0.03). Between-group differences were not significant for RMDQ or any secondary outcomes (e.g., pain) at any time. People reporting pain when standing and walking at baseline (n = 59) reported a greater reduction in RMDQ at 12 months in the flat sole group (-4.4 [95% CI, -6.0 to -2.8], n = 29) than the rocker sole group (-2.0 [95% CI, -3.6 to -0.4], n = 30) (P shoes seem to be no more beneficial than flat sole shoes in affecting disability and pain outcomes in

    Various interventions are available for the treatment of chronic low back pain (LBP), including Manual Therapy and Cognitive Behavioural Therapy (CBT). The purpose of this study is to evaluate whether the addition of an internet-based CBT program leads to better outcomes in patients who are treated with multimodal manual therapy for chronic LBP. A randomized controlled trial comparing a combined intervention, consisting of internet-based CBT utilising MoodGYM plus multimodal manual therapy, to multimodal manual therapy alone for patients with chronic LBP. Multimodal manual therapy will be delivered by experienced chiropractors and physiotherapists. Treatment sessions will consist of a combination of joint and soft tissue mobilisation; spinal manipulation as well as muscle and fascia massage; education and reassurance; and rehabilitative exercise prescription. In total, 108 adult participants will be recruited from multiple chiropractic and physiotherapy private practices in Australia. Participants older than 18 years of age and diagnosed with chronic non-specific LBP will be included in the trial, where chronic LBP is defined as continuous or fluctuating pain for a minimum of three months. The Keele STarT Back screening tool will be used to screen for potential participants who are in the medium risk category. The primary outcomes are self efficacy and disability measured by the Patient Self-Efficacy Questionnaire (PSEQ) and Roland Morris Disability Questionnaire (RMDQ) respectively. Secondary outcome measures will assess pain, catastrophising, depression, anxiety, stress and work ability. Participants will be randomly allocated into one of two groups. Both groups will receive an upper limit of 12 multimodal manual therapy sessions over a period of 8 weeks. The intervention group will also receive five weeks of MoodGYM covering five modules in total. Assessment will be conducted at pre-treatment, post-treatment 8- and follow-up at 26- and 52 weeks.

    Little is known about the affected cognitive problems in chronic low back pain patients. For this patient cohort research mostly focused on memory of pain, rather than cognitive difficulties related to pain. Chronic pain may be associated with specific (yet undefined) cognitive deficits that affect everyday behaviour. We set out to compare the cognitive function of patients with chronic low back pain (cLBP) in the course of multidisciplinary pain treatments before and after therapy. Thirty-three patients with cLBP and 25 healthy controls between 20 and 70 years were recruited into the study. The inclusion criteria for patients were: (1) a history of at least 12 weeks of chronic myofascial low back pain without radicular pain sensation before enrolment; (2) grade II and higher chronicity according to von Korff; (3) no opioid medication. The patients recruited had a mean pain duration of 7.13±7.16 years and reported a mean pain intensity of 6.62±2.04 (visual analogue score, VAS). Their mean back function according to the Funktionsfragebogen Hannover (FFbH, a questionnaire comparable with the Health Assessment Questionnaire) was 52.39±20.23%. At three time points (before therapy, 3 weeks and 6 months after therapy) the study subjects were assessed prospectively with a battery of visual memory tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). These included choice reaction time (CRT), pattern recognition memory (PRM) and spatial span (SSP). In parallel, the Trail-Making Test (TMT-A, TMT-B) and the Wechsler Adult Intelligence Scale (WAIS-III) were used to evaluate intelligence and cognitive flexibility. At the beginning of MDPT (T1), it took patients with cLBP significantly longer than HC to complete TMT-A (38.29±19.99s vs 30.25±14.19s, p=0.047) and TMT-B (72.10±26.98s vs 55.99±22.14s, p=0.034). There were no significant differences between patients and HC in CRT, PRM and SSP. Three weeks (T2) and 6 months (T3) after MDPT, TMT

    Most dental practitioners act as their own radiographer and radiologist, unlike their medical colleagues. Virtually all dental surgeons have a dental X-ray machine for intraoral radiography available to them and 40% of dental practices have equipment for dental panoramic tomography. Because of the low energy of X-ray equipment used in dentistry, radiation incidents tend to be less serious than those associated with other aspects of patient care. Details of 47 known incidents are given. The advent of the 1985 and 1988 Ionising Radiation Regulations has made dental surgeons more aware of the hazards of radiation. These regulations, and general health and safety legislation, have led to a few dental surgeons facing legal action. Because of the publicity associated with these court cases, it is expected that there will be a decrease in radiation incidents arising from the practice of dentistry. (author)

    Cross-sectional study. Comparison of the timing of onset of lateral abdominal muscle activity during rapid arm movements in patients with nonspecific chronic low back pain (cLBP) and back-pain-free controls. Rapid movements of the arm are normally associated with prior activation of trunk-stabilizing muscles in readiness for the impending postural perturbation. Using invasive intramuscular electromyography techniques, studies have shown that this feed-forward function is delayed in some patients with low back pain (LBP). Ultrasound tissue Doppler imaging (TDI) provides an ultrasound method for quantifying muscle activation in a noninvasive manner, allowing investigation of larger groups of patients and controls. Ninety-six individuals participated (48 patients with cLBP and 48 matched LBP-free controls). During rapid shoulder flexion, abduction, and extension, surface electromyographic signals from the deltoid and motion-mode TDI images from the contralateral lateral abdominal muscles were recorded simultaneously. The onset of muscle activity was given by changes in the tissue velocity of the abdominal muscles, as measured with TDI. Pain and disability in the patients were assessed using standardized questionnaires. Data were analyzed using repeated measures analysis of variance. In both groups, feed-forward activity of the lateral abdominal muscles was recorded during arm movements in all directions. The main effect of "group membership" revealed no significant difference between the groups for the earliest onset of abdominal muscle activity (P = 0.398). However, a significant "group x body side" interaction (P = 0.015) was observed, and this was the result of earlier onsets in the cLBP group than controls for the abdominal muscles on the right (but not left) body side. No relationship was found between the time of onset of the earliest abdominal muscle activity and pain intensity, pain frequency, pain medication usage, or Roland Morris disability scores. Patients

    "Mechanical Diagnosis and Therapy" (MDT) (also known as the McKenzie method), like other interventions for low back pain (LBP), has been found to have small effects for people with LBP. It is possible that a group of patients respond best to MDT and have larger effects. Identification of patients who respond best to MDT compared with other interventions would be an important finding. The purpose of the study was to investigate whether baseline characteristics of patients with chronic LBP, already classified as derangement syndrome, can identify those who respond better to MDT compared with Back School. This study was a secondary analysis of data from a previous trial comparing MDT with Back School in 148 patients with chronic LBP. Only patients classified at baseline assessment as being in the directional preference group (n=140) were included. The effect modifiers tested were: clear centralization versus directional preference only, baseline pain location, baseline pain intensity, and age. The primary outcome measures for this study were pain intensity and disability at the end of treatment (1 month). Treatment effect modification was evaluated by assessing the group versus predictor interaction terms from linear regression models. Interactions ≥1.0 for pain and ≥3 for disability were considered clinically important. Being older met our criteria for being a potentially important effect modifier; however, the effect occurred in the opposite direction to our hypothesis. Older people had 1.27 points more benefit in pain reduction from MDT (compared with Back School) than younger participants after 1 month of treatment. The sample (n=140) was powered to detect the main effects of treatment but not to detect the interactions of the potential treatment effect modifiers. The results of the study suggest older age may be an important factor that can be considered as a treatment effect modifier for patients with chronic LBP receiving MDT. As the main trial was not

    Full Text Available Advanced Technology and early detection of disease by recent improvements in investigation modalities lead to decreased incidents of amputations while Road Traffic Accidents (RTA increase. Furthermore, it leads to variation and decreased morbidity, mortality and accidents (crush injuries, and better equipped and trained staff, specialist services, diabetic food, rehabilitation centres, and giving good support physically and psychologically for Amputated patients. OBJECTIVE To know incidence rates of Emergency Amputation who attended causality with advanced disease and severe Trauma. METHODOLOGY The study is done over a period of one year i.e. between June 2015 to June 2016 who attended causality with advanced and severe disease affecting the limbs either due to diabetes, trauma or vascular diseases. RESULTS During one-year period, total 6,371 patients attended for general surgery OP. In those, 187 patients needed emergency surgery which included both major and minor operations. Among those, 81 patients were amputated. CONCLUSION As per our available records and observation, even though there is increased literacy and access to advanced technology, there is still increased incidence of patients undergoing amputations due to diseases. Therefore, there is a need to improve awareness and importance of early detection of diabetes, hazards of smoking, and regular general health checkups for patients at root level. With that we can treat diabetes and/or any disease in time. So there must be awareness in peripheral health staff i.e. PHC, subcentres, and community health centres about early detection of disease which in turn improves the quality of life of the patient. Due to diabetes slight injury to the glucose laden tissue may cause chronic infection and ulcer formation.(1 The tumours are seen commonly in the age group of 20-40 years after bone fusion, bones affected commonly are those around the knee (lower end of knee, upper end of tibia.

    Full Text Available Objectives. To identify the efficacy of auricular acupressure on pain and disability for chronic LBP by systematic review. Methods. A search of randomized controlled trials was conducted in four English medical electronic databases and three Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed using all time-points meta-analysis. Results. A total of 7 trials met the inclusion criteria, of which 4 had the low risk of bias. The findings of this study showed that, for the immediate effect, auricular acupressure had large, significant effects in improving pain within 12 weeks. As for the follow-up effect, the pooled estimates also showed promising effect at 4-week follow-up after 4-week intervention (standardized mean difference = −1.13, 95% CI (-1.70, -0.56, P<0.001. But, for the disability level, the therapeutic effect was not significant (mean difference = −1.99, 95% CI (-4.93, 0.95, P=0.18. No serious adverse effects were recorded. Conclusions. The encouraging evidence of this study indicates that it is recommended to provide auricular acupressure to patients with chronic low back pain. However, a more accurate estimate of the effect will require further rigorously designed large-scale RCTs on chronic LBP for improving pain and disability.

  17. Lightning incidents in Mongolia

    Full Text Available This is one of the first studies that has been conducted in Mongolia on the distribution of lightning incidents. The study covers a 10-year period from 2004 to 2013. The country records a human death rate of 15.4 deaths per 10 million people per year, which is much higher than that of many countries with similar isokeraunic level. The reason may be the low-grown vegetation observed in most rural areas of Mongolia, a surface topography, typical to steppe climate. We suggest modifications to Gomes–Kadir equation for such countries, as it predicts a much lower annual death rate for Mongolia. The lightning incidents spread over the period from May to August with the peak of the number of incidents occurring in July. The worst lightning affected region in the country is the central part. Compared with impacts of other convective disasters such as squalls, thunderstorms and hail, lightning stands as the second highest in the number of incidents, human deaths and animal deaths. Economic losses due to lightning is only about 1% of the total losses due to the four extreme weather phenomena. However, unless precautionary measures are not promoted among the public, this figure of losses may significantly increase with time as the country is undergoing rapid industrialization at present.

    Low back pain (LBP) is one of the most common health problems in adults. The impact of LBP on the individual can cause loss of health status and function related to pain in the back. To reduce the impact of LBP on adults, drug therapy is the most frequently recommended intervention. But over the last decade, a substantial number of randomized clinical trials of non-pharmacological intervention for LBP have been published. To determine the effectiveness of acupuncture, acupressure and chiropractic (non-pharmacological) interventions on the treatment of chronic nonspecific low back pain in Iran. Systematic review and meta-analysis. A systematic literature search was completed without date restrictions up to May 2013 in five major databases (Medline, CINAHL, Science Direct, CAJ Full-text Database, and Cochrane databases). Only randomized controlled trials published in Persian (Farsi) or English languages were included. Two independent reviewers extracted the data. The quality of the papers was assessed using the Cochrane Back Review Risk of Bias criteria. Initial searches revealed 415 papers, 382 of which were excluded on the basis of abstract alone. After excluding 23 papers due to duplication, the remaining 10 trial papers were subjected to a more detailed analysis of the full text, which resulted in three being excluded. The seven remaining trials had a lack of methodological and clinical homogeneity, precluding a meta-analysis. The trials used different comparators with regards to the primary outcomes, the number of treatments, the duration of treatment and the duration of follow-up. This systematic review demonstrates that acupuncture, acupressure and chiropractic may have a favorable effect on self-reported pain and functional limitations on NSCLBP. However, the results should be interpreted in the context of the limitations identified, particularly in relation to the heterogeneity in the study characteristics and the low methodological quality in many of the

    Sleep problems are common in people with low back pain (LBP); however, the mechanisms of how sleep influences pain are complex. To date there is a lack of prospective research on the timing and development of sleep problems in those who have LBP; such information would be useful to identify individuals at risk for poor outcomes. Our aims are to investigate the predictive role of sleep problems on self-report recovery and pain intensity using logistic regression reporting odds ratios (ORs). An observational cohort of 761 chronic LBP patients recruited from a pain management clinic participated, and they completed data at baseline and at 6-month follow-up (n = 682). Results show increased odds for reported nonrecovery (OR 1.52) and pain intensity (OR 2.69) among those who reported sleep problems at baseline. Further analysis on the experience of sleep problems through time showed that those with developing sleep problems (ie, no sleep problems at baseline but reported sleep problems at follow-up) were at increased odds for reporting nonrecovery (OR 2.17) and pain intensity (OR 2.95), as were those who reported sleep problems at both baseline and follow-up, for recovery (OR 2.88) and pain intensity (OR 3.45). Those with resolving sleep problems (ie, sleep problems present at baseline but not at follow-up) were at decreased odds for nonrecovery (OR 0.50) and pain intensity (0.49). Presenting, persistent, and developing sleep problems have a significant impact on recovery for those with LBP. Clinicians may wish to consider treatment options that can address sleep problems. © 2017 World Institute of Pain.

    Constipation is one of the most prevalent conditions in primary care settings and increases the risk of cardiovascular disease, potentially through processes mediated by altered gut microbiota. However, little is known about the association of constipation with CKD. In a nationwide cohort of 3,504,732 United States veterans with an eGFR ≥60 ml/min per 1.73 m 2 , we examined the association of constipation status and severity (absent, mild, or moderate/severe), defined using diagnostic codes and laxative use, with incident CKD, incident ESRD, and change in eGFR in Cox models (for time-to-event analyses) and multinomial logistic regression models (for change in eGFR). Among patients, the mean (SD) age was 60.0 (14.1) years old; 93.2% of patients were men, and 24.7% were diabetic. After multivariable adjustments, compared with patients without constipation, patients with constipation had higher incidence rates of CKD (hazard ratio, 1.13; 95% confidence interval [95% CI], 1.11 to 1.14) and ESRD (hazard ratio, 1.09; 95% CI, 1.01 to 1.18) and faster eGFR decline (multinomial odds ratios for eGFR slope constipation associated with an incrementally higher risk for each renal outcome. In conclusion, constipation status and severity associate with higher risk of incident CKD and ESRD and with progressive eGFR decline, independent of known risk factors. Further studies should elucidate the underlying mechanisms. Copyright © 2017 by the American Society of Nephrology.

    Full Text Available Background and objectives: Suboptimal breathing patterns and impairments of posture and trunk stability are often associated with musculoskeletal complaints such as low back pain. Respiration is also affected by poor neuromuscular control of core muscles. Immediate effects of hemibridge with ball and balloon exercise has been studied on chronic pain in athlete population. Objective: To evaluate the effects of hemibridge with ball and balloon exercise on pain, forced expiratory volume and functional abilities in patients with chronic low back pain using Visual Analogue Scale (VAS, Forced Expiratory Volume (FEV and Modified Oswestry Disability Questionnaire (MODQ. Methods: The present experimental study was conducted among 30 participants between the age of 21 to 55 years with chronic non-specific LBP. The participants were given a hemibridge with ball and balloon exercise. Pre-interventional and 3rd day Post-interventional outcome measurements were taken using VAS, FEV1 and FEV6 and MODQ. Results: The difference between pre-and post of VAS was statistically highly significant (p=0.0001. The p value of FEV6 and MODQ by paired t test was statistically significant with p value of 0.02 and 0.0007 respectively. Conclusion: The study concludes that there is an immediate effect of hemibridge with ball and balloon exercise on pain, FEV6 and functional ability in patients with chronic LBP.

    Full Text Available Objective: Low back pain (LBP is one of the most common and costly health problems. Changes in muscle activity and recruitment of lumbar deep muscles which are responsible for lumbar spine stability have been reported in patients with LBP. Different exercise programs are used in the treatment of such patients to improve spinal stability. The purpose of this study was to systematically review the effect of stabilization exercises on objective outcome measures in patients with non-specific chronic LBP in previous randomized controlled trials. Materials & Methods: A literature search for the period of 2000-2012 was performed, using MEDLINE, PubMed, Google scholar, Science Direct, OVID and CINAHL databases. Low back pain, stabilization exercise, motor control exercise, segmental stabilization, transverse abdominis muscle, multifidus muscle, electromyography, ultrasound, ultrasonography, and randomized controlled trial were used as keywords. Muscle recruitment, postural balance control, muscle endurance, muscle size and lumbar range of motion were studied as objective outcome measures.  Results: In total, of 158 articles, 13 articles were selected according to the inclusion criteria of the study. There was a wide variation among studies in terms of methodology, main outcome measures, sample size, procedure, etc. The results demonstrated that stabilization exercise was more effective than other interventions on activity pattern of deep muscles, postural balance control, muscle endurance and range of motion, while it was not significantly different with other interventions on deep muscle size.  Conclusion: It seems that stabilization exercise has considerable effect on activity pattern of deep muscles, postural control, muscle endurance and range of motion and can be considered as an effective intervention in the treatment of patients with non-specific chronic LBP

    1985-01-01

    This report documents the circumstances contributing to the inadvertent melting of cobalt 60 (Co-60) contaminated scrap metal in two Mexican steel foundries and the subsequent distribution of contaminated steel products into the United States. The report addresses mainly those actions taken by US Federal and state agencies to protect the US population from radiation risks associated with the incident. Mexico had much more serious radiation exposure and contamination problems to manage. The United States Government maintained a standing offer to provide technical and medical assistance to the Mexican Government. The report covers the tracing of the source to its origin, response actions to recover radioactive steel in the United States, and return of the contaminated materials to Mexico. The incident resulted in significant radiation exposures within Mexico, but no known significant exposure within the United States. Response to the incident required the combined efforts of the Nuclear Regulatory Commission (NRC), Department of Energy, Department of Transportation, Department of State, and US Customs Service (Department of Treasury) personnel at the Federal level and representatives of all 50 State Radiation Control Programs and, in some instances, local and county government personnel. The response also required a diplomatic interface with the Mexican Government and cooperation of numerous commercial establishments and members of the general public. The report describes the factual information associated with the event and may serve as information for subsequent recommendations and actions by the NRC. 8 figures

    2014-01-01

    Background: Low back pain (LBP) is a common complaint in population that lowers the quality of life. The main etiology of LBP is recognized in about 20% of patients while it is attributed to lumbar disk herniation (LDH) in 80% of cases and causes some unnecessary lumbar surgeries without realizing the definite cause. Objectives: This study was planned to evaluate the etiologies of LBP in patients who had LDH to clarify whether the disc herniation is the main cause of patients` pain or other diseases were responsible for this kind of pain. Materials and Methods: In this cross-sectional study, we analyzed the medical profiles of the patients with proven LDH in a private clinic in Mashhad City, Iran, between 2005 and 2012, for demographic and the etiologies of LBP with clinical and paraclinical studies. We also calculated the incidence of each etiology by SPSS 13. Results: In our study, among 1250 patients with proven LDH by MRI, 500 patients (40%) had chronic LBP and the most common causes of LBP were heavy constant working (40.2%), osteoporosis (35.6%), and sacroiliac joint pain (34.6%), consecutively. Interestingly, LDH had the ninth rank among the common cause of LBP. Conclusions: In this study, we found that in spite of previous beliefs, discopathies were not common etiologies of LBP. Thus, even in patients with proven LDH by imaging studies, the physician should perform a thorough evaluation for other causes of LBP to avoid unnecessary lumbar surgeries. PMID:25763198

This study aims to assess the reporting rate of medication incidents in NHS facilities in the north east of Scotland, and to describe the types and outcomes of reported incidents among different services. Furthermore, we wished to quantify the proportion of reported incidents according to the reporters\\' profession. METHODS: A retrospective description was made of medication incidents reported to an online reporting system (DATIX) over a 46-month-period (July 2005 to April 2009). Reports originated from acute and community hospitals, mental health, and primary care facilities. RESULTS: Over the study period there were 2,666 incidents reported with a mean monthly reporting rate of 78.2\\/month (SD±16.9). 6.1% of all incidents resulted in harm, with insulin being the most commonly implicated medication. Nearly three-quarters (74.2%, n=1,978) of total incidents originated from acute hospitals. Administration incidents were implicated in the majority of the reported medication incidents (59%), followed by prescribing (10.8%) and dispensing (9.9%), while the nondescript "other medication incidents" accounted for 20.3% of total incidents. The majority of reports were made by nursing and midwifery staff (80%), with medical and dental professionals reporting the lowest number of incidents (n=56, 2%). CONCLUSIONS: The majority of medication incidents in this study were reported by nursing and midwifery staff, and were due to administration incidents. There is a clear need to elucidate the reasons for the limited contribution of the medical and dental professionals to reporting medication incidents.

    Abstract The Pilates method has recently become a fast-growing popular way of exercise recommended for healthy individuals and those engaged in rehabilitation. Several published studies have examined the effects of Pilates method in people with chronic low back pain (LBP). The objective of this study is to describe and provide an extensive overview of the scientific literature comparing the effectiveness of the Pilates method on pain and disability in patients with chronic nonspecific LBP. The study is based on the data from the following sources: MEDLINE-NLM, MEDLINE-EBSCO, Scopus Elsevier, Cochrane, DOAJ, SciELO, and PLOSONE. Original articles and systematic reviews of adults with chronic nonspecific LBP that evaluated pain and/or disability were included in this study; studies in which the primary treatment was based on Pilates method exercises compared with no treatment, minimal intervention, other types of intervention, or other types of exercises. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were adopted. The literature search included 7 electronic databases and the reference list of relevant systematic reviews and original articles to July 2014. Two independent investigators conducted the literature search and performed the synthesis as follows: Study Design; Sample (n); Disability measure; Intervention; and Main results. The searches identified a total of 128 articles. From these, 29 were considered eligible and were included in the analysis. The items were stratified as follows: Pilates method versus other kind of exercises (n = 6 trials) and Pilates method versus no treatment group or minimal intervention for short-term pain (n = 9 trials); the therapeutic effect of the Pilates method in randomized cohorts (n = 5); and analysis of reviews (n = 9). We found that there is a dearth of studies that clearly demonstrates the efficacy of a specific Pilates exercise program over another in the treatment of chronic pain. However

    Full Text Available INTRODUCTION. The incidence of cancer among residents in sites contaminated by pollutants with a possible health impact is not adequately studied. In Italy, SENTIERI Project (Epidemiological study of residents in National Priority Contaminated Sites, NPCSs was implemented to study major health outcomes for residents in 44 NPCSs. METHODS. The Italian Association of Cancer Registries (AIRTUM records cancer incidence in 23 NPCSs. For each NPCSs, the incidence of all malignant cancers combined and 35 cancer sites (coded according to ICD-10, was analysed (1996-2005. The observed cases were compared to the expected based on age (5-year period,18 classes, gender, calendar period (1996-2000; 2001-2005, geographical area (North-Centre and Centre-South and cancer sites specific rates. Standardized Incidence Ratios (SIR with 90% Confidence Intervals were computed. RESULTS. In both genders an excess was observed for overall cancer incidence (9% in men and 7% in women as well as for specific cancer sites (colon and rectum, liver, gallbladder, pancreas, lung, skin melanoma, bladder and Non Hodgkin lymphoma. Deficits were observed for gastric cancer in both genders, chronic lymphoid leukemia (men, malignant thyroid neoplasms, corpus uteri and connective and soft-tissue tumours and sarcomas (women. DISCUSSION. This report is, to our knowledge, the first one on cancer risk of residents in NPCSs. The study, although not aiming to estimate the cancer burden attributable to the environment as compared to occupation or life-style, supports the credibility of an etiologic role of environmental exposures in contaminated sites. Ongoing analyses focus on the interpretation of risk factors for excesses of specific cancer types overall and in specific NPCSs in relation to the presence of carcinogenic pollutants.

    A basic premise for any instrument measuring spinal motion is that reliable outcomes can be obtained on a relevant sample under standardized conditions. The purpose of this study was to assess the overall reliability and measurement error of regional spinal sagittal plane motion in patients with chronic low back pain (LBP), and then to evaluate the influence of body mass index, examiner, gender, stability of pain, and pain distribution on reliability and measurement error. This study comprises a test-retest design separated by 7 to 14 days. The patient cohort consisted of 220 individuals with chronic LBP. Kinematics of the lumbar spine were sampled during standardized spinal extension-flexion testing using a 6-df instrumented spatial linkage system. Test-retest reliability and measurement error were evaluated using interclass correlation coefficients (ICC(1,1)) and Bland-Altman limits of agreement (LOAs). The overall test-retest reliability (ICC(1,1)) for various motion parameters ranged from 0.51 to 0.70, and relatively wide LOAs were observed for all parameters. Reliability measures in patient subgroups (ICC(1,1)) ranged between 0.34 and 0.77. In general, greater (ICC(1,1)) coefficients and smaller LOAs were found in subgroups with patients examined by the same examiner, patients with a stable pain level, patients with a body mass index less than below 30 kg/m(2), patients who were men, and patients in the Quebec Task Force classifications Group 1. This study shows that sagittal plane kinematic data from patients with chronic LBP may be sufficiently reliable in measurements of groups of patients. However, because of the large LOAs, this test procedure appears unusable at the individual patient level. Furthermore, reliability and measurement error varies substantially among subgroups of patients. Copyright © 2014 Elsevier Inc. All rights reserved.

    Sixteen-week intervention for chronic patients with low back pain (LBP) with 9-month follow-up. Primary randomization at 4 weeks into either supervised Swiss ball exercise or an exercise advice group. To evaluate changes in disability and pain in individuals with chronic LBP after combined treatment and exercise interventions, and to evaluate whether changes in self-report or physical measures would best explain improvements in disability There is a need to understand what the effectiveness of a clinically applicable treatment intervention is for an individual's perception of their back pain. There is insufficient evidence about the different combinations of manual treatment that commonly precede involvement in exercise programs. Sixty individuals with chronic nonspecific LBP (at least 3-month duration) were randomly assigned (after 4 weeks of manipulative or nonmanipulative treatment) to either a supervised Swiss ball exercise group, or an advice group. The exercise intervention was for 12 weeks with a long-term follow-up of 9 months. Self-report measures and physical measures (endurance times and myoelectric fatigue) were collected throughout the study. Self-rated disability improved more after the treatment period for individuals who received supervised exercise compared with advice alone. There was no difference found between individuals who received manipulative or nonmanipulative treatment. Multiple regression analysis found that self-report measures best explained improvements in disability throughout the study. Long-term findings showed no group differences. Supervised exercise is a more successful subsequent to manual treatment compared with exercise advice. The improvements associated with this type of program were primarily manifested in the psychologic self-report measures rather than physical measurements.

    Full Text Available Background and Aims: Caudal epidural steroid administration is an effective treatment for chronic low back pain (LBP. Fluoroscopy guidance is the gold standard for pain procedures. Ultrasound guidance is recently being used in pain clinic procedures. We compared the fluoroscopy guidance and ultrasound guidance for caudal epidural steroid injection with respect to the time needed for correct placement of the needle and clinical effectiveness in patients with chronic LBP. Methods: Fifty patients with chronic LBP with radiculopathy, not responding to conventional medical management, were randomly allocated to receive injection depot methyl prednisolone (40 mg through caudal route either using ultrasound guidance (Group U, n = 25 or fluoroscopy guidance (Group F, n = 25. Pre-procedural visual analogue scale (VAS score and Oswestry Disability Index (ODI were noted. During the procedure, the time needed for correct placement of needle was observed. Adverse events, if any, were also noted. All patients were followed up for next 2 months to evaluate Visual Analogue Scale (VAS score and ODI at the 2nd week and again at the end of 1st and 2nd month. Results: The needle-placement time was less using ultrasound guidance as compared to fluoroscopy guidance (119 ± 7.66 vs. 222.28 ± 29.65 s, respectively,P< 0.001. Significant reduction in VAS score and ODI (clinical improvement was noted in the follow-up time points and comparable between the groups at all time points. Conclusion: Ultrasound guidance can be a safe alternative tool for achieving faster needle placement in caudal epidural space. Clinical effectiveness (reduction of VAS and ODI scores remains comparable between both the techniques.

    There is a controversy regarding whether core stability exercise (CSE) is more effective than general exercise (GE) for chronic LBP. To compare different exercises regarding their effect on improving back strength and stability, performance of abdominal muscles is a useful index. Ultrasound imaging for measuring muscle thickness could be used to assess muscle performance. The aim of this study was to compare CSE and GE in chronic LBP using ultrasound imaging for measurement of thickness of the deep stabilizing and main global trunk muscles in non-specific chronic LBP. Each program included 16 training sessions three times a week. Using ultrasound imaging, four transabdominal muscle thickness were measured before and after the intervention. Disability and pain were measured as secondary outcomes. After the intervention on participants (n = 43), a significant increase in muscle thickness (hypertrophy) was seen only in right and left rectus abdominis in the GE group, but significant difference to the CSE group was only on the right side. Disability and pain reduced within the groups without a significant difference in the change between them. The present results provided evidence that only GE increased right and left rectus muscle thickness. The only significant difference between CSE and GE groups was the right rectus thickness. As rectus is a global muscle, the effect of GE on strength improvement (one side stronger than the other) may have a negative effect on motor control of lumbopelvic muscles and possibly increase the risk of back pain occurring or becoming worse, though this was not observed in the present study.

    Yoga is effective for mild to moderate chronic low back pain (cLBP), but its comparative effectiveness with physical therapy (PT) is unknown. Moreover, little is known about yoga's effectiveness in underserved patients with more severe functional disability and pain. To determine whether yoga is noninferior to PT for cLBP. 12-week, single-blind, 3-group randomized noninferiority trial and subsequent 40-week maintenance phase. (ClinicalTrials.gov: NCT01343927). Academic safety-net hospital and 7 affiliated community health centers. 320 predominantly low-income, racially diverse adults with nonspecific cLBP. Participants received 12 weekly yoga classes, 15 PT visits, or an educational book and newsletters. The maintenance phase compared yoga drop-in classes versus home practice and PT booster sessions versus home practice. Primary outcomes were back-related function, measured by the Roland Morris Disability Questionnaire (RMDQ), and pain, measured by an 11-point scale, at 12 weeks. Prespecified noninferiority margins were 1.5 (RMDQ) and 1.0 (pain). Secondary outcomes included pain medication use, global improvement, satisfaction with intervention, and health-related quality of life. One-sided 95% lower confidence limits were 0.83 (RMDQ) and 0.97 (pain), demonstrating noninferiority of yoga to PT. However, yoga was not superior to education for either outcome. Yoga and PT were similar for most secondary outcomes. Yoga and PT participants were 21 and 22 percentage points less likely, respectively, than education participants to use pain medication at 12 weeks. Improvements in yoga and PT groups were maintained at 1 year with no differences between maintenance strategies. Frequency of adverse events, mostly mild self-limited joint and back pain, did not differ between the yoga and PT groups. Participants were not blinded to treatment assignment. The PT group had disproportionate loss to follow-up. A manualized yoga program for nonspecific cLBP was noninferior to PT for

    The aim of this trial was to establish the effectiveness of traditional bone setting (TBS) compared with conventional physical and exercise therapy (PhT) in treating chronic low back pain (cLBP). Randomised clinical trial. Working-aged cLBP patients (n=131, age range 29-51 years) were randomised into two treatment groups: TBS and PhT. Follow-up assessments took place 1, 6 and 12 months after treatment. TBS is a popular traditional manual mobilisation therapy for musculoskeletal disorders in Finland. Conventional PhT was used as the reference treatment. LBP intensity (Visual Analog Scale 0-100, VAS), the Oswestry Disability Index (ODI), the global assessment score (scale -1 to +10), a health-related quality of life (HRQoL) assessment and spine mobility measurements were used as measures. 118 patients (95.9%, 59 men and 59 women) completed the treatment program. Both treatments reduced the VAS and ODI levels after 1 month. Changes in VAS did not differ between the two treatment groups (mean -0.2, CI -11.3 to 10.9). The improvement in ODI (mean 2.4, CI -1.2 to 6.0, p=0.069, repeated measurements ANOVA) and quality of life scores (mean -0.03, CI -0.06 to 0, p=0.056) tended to be greater after TBS. Additionally, global assessment scores were better for TBS-treated patients (Mann-Whitney test, p=0.001). There were no differences between the spine mobility test results of the two groups. Changes in both VAS (mean -2.4, CI -15.5 to 10.6) and ODI (mean 1.0, CI -3.0 to 5.1) measures did not, however, differ between the groups at the 1-year follow-up stage. Most cLBP patients found the treatments to be beneficial. Although the long-term dynamics of pain and disability did not differ between the groups, the subjective benefits appeared to be more significant after TBS.

    National chronic dialysis data have had impact in the treatment planning. To report data of the annual survey of the Brazilian Society of Nephrology about chronic kidney disease patients on dialysis in July 2014. A survey based on data of dialysis units from the whole country. The data collection was performed by using a questionnaire filled out on-line by the dialysis units. Three hundred twelve (44%) of the dialysis units in the country answered the questionnaire. In July 2014, the total estimated number of patients on dialysis was 112,004. The estimated prevalence and incidence rates of chronic maintenance dialysis were 552 (range: 364 in the North region and 672 in the Southeast) and 180 patients per million population (pmp), respectively. The annual incidence rate of patients with diabetic nephropathy was 77 pmp. The annual gross mortality rate was 19%. For prevalent patients, 91% were on hemodialysis and 9% on peritoneal dialysis, 32,499 (29%) were on a waiting list of renal transplant, 37% were overweight/obese, 29% were diabetics, 16% had PTH levels > 600 pg/ml and 26% hemoglobin < 10 g/dl. A venous catheter was the vascular access for 17% of the hemodialysis patients. During 2011-2014 the prevalence and incidence rates of patients on dialysis tended to increase, while the gross mortality rate remained stable. In 2014, diabetes was the primary renal disease in 42% of the new dialysis patients.

In July 2016, the total estimated number of patients on dialysis was 122,825. The estimated prevalence and incidence rates of chronic maintenance dialysis were 596 (range: 344 in the North region and 700 in the Southeast) and 193 patients per million of population (pmp), respectively. The annual incidence rate of patients with diabetic nephropathy was 79 pmp. The annual gross mortality rate was 18.2%. For prevalent patients, 92% were on hemodialysis and 8% on peritoneal dialysis, and 29,268 (24%) were on a waiting list of renal transplant. A venous catheter was the vascular access for 20.5% of the hemodialysis patients. The prevalence rates of positive serology for hepatitis B and C showed a tendency to reduce from 2013 (1.4% and 4.2%, respectively) to 2016 (0.7% and 3.7%, respectively). The absolute number and the prevalence and incidence rates of patients on dialysis continue to rise steadily; the gross mortality rate remained stable. Regional inequities are evident in these rates.

Clinical Questions: Is core stability exercise more effective than general exercise in the treatment of patients with nonspecific low back pain (LBP)?  The authors searched the following databases: China Biological Medicine disc, Cochrane Library, Embase, and PubMed from 1970 through 2011. The key medical subject headings searched were chronic pain, exercise, LBP, lumbosacral region, and sciatica.  Randomized controlled trials comparing core stability exercise with general exercise in the treatment of chronic LBP were investigated. Participants were male and female adults with LBP for at least 3 months that was not caused by a specific known condition. A control group receiving general exercise and an experimental group receiving core stability exercise were required for inclusion in the meta-analysis. Core stability was defined as the ability to ensure a stable neutral spine position, but the type of exercise was not specified. Outcome measures of pain intensity, back-specific functional status, quality of life, and work absenteeism were recorded at 3-, 6-, and 12-month intervals.  The study design, participant information, description of interventions in the control and experimental groups, outcome measures, and follow-up period were extracted. The mean difference (MD) and 95% confidence interval (CI) were calculated to evaluate statistical significance. Risk of bias was assessed using the Cochrane Collaboration Recommendations, and all articles were rated as high risk for other bias with no further explanation given.  Five studies involving 414 patients were included. Four studies assessed pain intensity using the visual analog scale or numeric rating scale.

    2012-01-01

    Background Medical work capacity evaluations play a key role in social security schemes because they usually form the basis for eligibility decisions regarding disability benefits. However, the evaluations are often poorly standardized and lack transparency as decisions on work capacity are based on a claimant’s disease rather than on his or her functional capacity. A comprehensive and consistent illustration of a claimant’s lived experience in relation to functioning, applying the International Classification of Functioning, Disability and Health (ICF) and the ICF Core Sets (ICF-CS), potentially enhances transparency and standardization of work capacity evaluations. In our study we wanted to establish whether and how the relevant content of work capacity evaluations can be captured by ICF-CS, using disability claimants with chronic widespread pain (CWP) and low back pain (LBP) as examples. Methods Mixed methods study, involving a qualitative and quantitative content analysis of medical reports. The ICF was used for data coding. The coded categories were ranked according to the percentage of reports in which they were addressed. Relevance thresholds at 25% and 50% were applied. To determine the extent to which the categories above the thresholds are represented by applicable ICF-CS or combinations thereof, measures of the ICF-CS’ degree of coverage (i.e. content validity) and efficiency (i.e. practicability) were defined. Results Focusing on the 25% threshold and combining the Brief ICF-CS for CWP, LBP and depression for CWP reports, the coverage ratio reached 49% and the efficiency ratio 70%. Combining the Brief ICF-CS for LBP, CWP and obesity for LBP reports led to a coverage of 47% and an efficiency of 78%. Conclusions The relevant content of work capacity evaluations involving CWP and LBP can be represented by a combination of applicable ICF-CS. A suitable standard for documenting such evaluations could consist of the Brief ICF-CS for CWP, LBP, and

To determine the extent to which the categories above the thresholds are represented by applicable ICF-CS or combinations thereof, measures of the ICF-CS’ degree of coverage (i.e. content validity and efficiency (i.e. practicability were defined. Results Focusing on the 25% threshold and combining the Brief ICF-CS for CWP, LBP and depression for CWP reports, the coverage ratio reached 49% and the efficiency ratio 70%. Combining the Brief ICF-CS for LBP, CWP and obesity for LBP reports led to a coverage of 47% and an efficiency of 78%. Conclusions The relevant content of work capacity evaluations involving CWP and LBP can be represented by a combination of applicable ICF-CS. A suitable standard for documenting such evaluations could consist of the Brief ICF

    Defined by lasting more than four weeks - is a common but often challenging clinical scenario. It is important to be aware that diarrhoea means different things to different patients. The evaluation of chronic diarrhoea depends on taking an excellent history and careful physical examination as well as planning investigations thoughtfully. Functional diarrhea ist the most common cause of chronic diarrhea in the developed countries and motility disorders are more common than inflammatory, osmotic or secretory causes. In some cases categorizing patients by their stool characteristics can be helpful in directing further evaluation.

    Conclusion Though it is claimed that MCE increases spinal stability, the lack of significant difference in the results of variables between the two groups may be due to our MCE not being specific for increasing spinal stability or equal effects of both interventions on increasing spinal stability and no preference of MCE. It may also be due to poor sensitivity of our outcome measures in detecting changes in spinal stability, especially with respect to the sample size. Based on these results, it could be concluded that MCE is not more effective than GE in improving endurance core stability tests and reducing disability and pain in chronic non-specific LBP patients.

    Chronic low back pain (LBP) is a prevalent condition associated with pain, disability, decreased quality of life, and fear of movement. To date, no studies have compared the effectiveness of spinal manipulation and functional technique for the management of this population. This study aimed to compare the effectiveness of spinal manipulation and functional technique on pain, disability, kinesiophobia, and quality of life in patients with chronic LBP. A single-blind pragmatic randomized controlled trial conducted in a university research clinic was carried out. Sixty-two patients (62% female, age: 45±7) with chronic LBP comprised the patient sample. Data on disability (Roland-Morris Disability Questionnaire [RMQ], Oswestry Low Back Pain Disability Index [ODI]), pain intensity (Numerical Pain Rate Scale [NPRS]), fear of movement (Tampa Scale of Kinesiophobia [TSK]), quality of life (Short Form-36 [SF-36] quality of life questionnaire), isometric resistance of abdominal muscles (McQuade test), and spinal mobility in flexion (finger-to-floor distance) were collected at baseline immediately after the intervention phase and at 1 month postintervention by an assessor blinded to group allocation of the patients. Patients were randomly assigned to the spinal manipulative therapy group or the functional technique group and received three once-weekly sessions. In comparison to patients receiving functional technique, those receiving spinal manipulation experienced statistically, although not clinically, significant greater reductions in terms of RMQ (standardized mean difference in score changes between groups at post-treatment: 0.1; at 1 month: 0.1) and ODI (post-treatment: 2.9; at 1 month: 1.4). Linear longitudinal analysis showed a significant improvement in both groups over time for RMQ (manipulative: F=68.51, ptreatment-by-time interactions were not detected for pain intensity (p=.488), TSK (p=.552), any domains of the SF-36 quality of life questionnaire (p≤.164), Mc

    Fear-avoidance beliefs are related to the prognosis of chronicity in low back pain in subacute stages, however in chronic pain, is no clear the influence of these factors; it has been suggested that the study population can determine the magnitude of influence on disability and pain of those suffering from back pain. Currently, information does not exist in the Mexican population. To analyze the relationship between fear-avoidance beliefs with pain and disability in Mexicans with chronic low back pain; analyze potentials differences between subgroups according to the time of evolution. Cross-sectional study in Mexicans with chronic LBP aged between 18 and 45. Data were collected on general socio demographic characteristics, time of evolution, body mass index, pain, disability and fear-avoidance beliefs. 33 men and 47 women, with an average age of 34.19±7.65 years. Higher scores of fear-avoidance beliefs were obtained in women (47.2±20.99 versus 38.5±9.7; p=0.05) and single participants (p=0.04). A positive correlation was found between disability (r=0.603, p<0.001) and pain (r=0.234, p=0.03) with high scores of fear-avoidance beliefs. Through generalized linear models for disability, total score of the fear avoidance beliefs questionnaire showed a standardized beta coefficient of 0.603, p<0.001 (R 2 of 0.656); for pain showed a standardized beta coefficient of 0.29, p=0.01 (R 2 of 0.721). The present study suggests that there is a strong relationship between pain severity, FABQ scores, and functional disability in Mexicans with chronic LBP. Copyright © 2016 Elsevier Editora Ltda.

    A Grazing Incidence Beam Expander (GIBE) telescope is being designed and fabricated to be used as an equivalent end mirror in a long laser resonator cavity. The design requirements for this GIBE flow down from a generic Free Electron Laser (FEL) resonator. The nature of the FEL gain volume (a thin, pencil-like, on-axis region) dictates that the output beam be very small. Such a thin beam with the high power levels characteristic of FELs would have to travel perhaps hundreds of meters or more before expanding enough to allow reflection from cooled mirrors. A GIBE, on the other hand, would allow placing these optics closer to the gain region and thus reduces the cavity lengths substantially. Results are presented relating to optical and mechanical design, alignment sensitivity analysis, radius of curvature analysis, laser cavity stability analysis of a linear stable concentric laser cavity with a GIBE. Fabrication details of the GIBE are also given.

    Abstract Prevalence of chronic gastritis has markedly declined in developed populations during the past decades. However, chronic gastritis is still one of the most common serious pandemic infections with such severe killing sequelae as peptic ulcer or gastric cancer. Globally, on average, even more than half of people may have a chronic gastritis at present. Helicobacter pylori infection in childhood is the main cause of chronic gastritis, which microbial origin is the key for the understanding of the bizarre epidemiology and course of the disease. A life-long and aggressive inflammation in gastritis results in destruction (atrophic gastritis) of stomach mucosa with time (years and decades). The progressive worsening of atrophic gastritis results subsequently in dysfunctions of stomach mucosa. Atrophic gastritis will finally end up in a permanently acid-free stomach in the most extreme cases. Severe atrophic gastritis and acid-free stomach are the highest independent risk conditions for gastric cancer known so far. In addition to the risks of malignancy and peptic ulcer, acid-free stomach and severe forms of atrophic gastritis may associate with failures in absorption of essential vitamins, like vitamin B12, micronutrients (like iron, calcium, magnesium and zinc), diet and medicines.

    Treatment of chronic low back pain (LBP) in older adults is limited by the adverse effects of analgesics. Effective nonpharmacologic treatment options are needed. To determine the effectiveness of a mind-body program at increasing function and reducing pain in older adults with chronic LBP. This single-blind, randomized clinical trial compared a mind-body program (n = 140) with a health education program (n = 142). Community-dwelling older adults residing within the Pittsburgh metropolitan area were recruited from February 14, 2011, to June 30, 2014, with 6-month follow-up completed by April 9, 2015. Eligible participants were 65 years or older with functional limitations owing to their chronic LBP (≥11 points on the Roland and Morris Disability Questionnaire) and chronic pain (duration ≥3 months) of moderate intensity. Data were analyzed from March 1 to July 1, 2015. The intervention and control groups received an 8-week group program followed by 6 monthly sessions. The intervention was modeled on the Mindfulness-Based Stress Reduction program; the control program, on the "10 Keys" to Healthy Aging. Follow-up occurred at program completion and 6 months later. The score on the Roland and Morris Disability Questionnaire was the primary outcome and measured functional limitations owing to LBP. Pain (current, mean, and most severe in the past week) was measured with the Numeric Pain Rating Scale. Secondary outcomes included quality of life, pain self-efficacy, and mindfulness. Intent-to-treat analyses were conducted. Of 1160 persons who underwent screening, 282 participants enrolled in the trial (95 men [33.7%] and 187 women [66.3%]; mean [SD] age,74.5 [6.6] years). The baseline mean (SD) Roland and Morris Disability Questionnaire scores for the intervention and control groups were 15.6 (3.0) and 15.4 (3.0), respectively. Compared with the control group, intervention participants improved an additional -1.1 (mean, 12.1 vs 13.1) points at 8 weeks and -0.04 (mean

    Heterogeneity exists within the low back pain (LBP) population. Some patients recover after every pain episode, whereas others suffer daily from LBP complaints. Until now, studies rarely make a distinction between recurrent low back pain (RLBP) and chronic low back pain (CLBP), although both are characterized by a different clinical picture. Clinical experiences also indicate that heterogeneity exists within the CLBP population. Muscle degeneration, like atrophy, fat infiltration, alterations in muscle fiber type, and altered muscle activity, compromises proper biomechanics and motion of the spinal units in LBP patients. The amount of alterations in muscle structure and muscle function of the paraspinal muscles might be related to the recurrence or chronicity of LBP. The aim of this experimental study is to evaluate differences in muscle structure (cross-sectional area and lean muscle fat index) and muscle activity of the multifidus (MF) and erector spinae (ES) during trunk extension, in patients with RLBP, non-continuous CLBP, and continuous CLBP. This cross-sectional study took place in the university hospital of Ghent, Belgium. Muscle structure characteristics and muscle activity were assessed by magnetic resonance imaging (MRI). Fifty-five adults with non-specific LBP (24 RLBP in remission, 15 non-continuous CLBP, 16 continuous CLBP) participated in this study. Total cross-sectional area, muscle cross-sectional area, fat cross-sectional area, lean muscle fat index, T2-rest and T2-shift were assessed. A T1-weighted Dixon MRI scan was used to evaluate spinal muscle cross-sectional area and fat infiltration in the lumbar MF and ES. Muscle functional MRI was used to evaluate the muscle activity of the lumbar MF and ES during a lumbar extension exercise. Before and after the exercise, a pain assessment was performed. This study was supported by grants from the Special Research Fund of Ghent University (DEF12/AOP/022) without potential conflict of interest

    Full Text Available OBJECTIVE: To describe the distribution of pediatric chronic kidney disease (CKD in Guatemala, estimate incidence and prevalence of pediatric end-stage renal disease (ESRD, and estimate time to progress to ESRD. METHODS: This study analyzed the registry of the only pediatric nephrology center in Guatemala, from 2004-2013. Incidence and prevalence were calculated for annual periods. Moran's index for spatial autocorrelation was used to determine significance of geographic distribution of incidence. Time to progress to ESRD and associated risk factors were calculated with multivariate Cox regression. RESULTS: Of 1 545 patients from birth to less than 20 years of age, 432 had chronic renal failure (CRF. Prevalence and incidence of ESRD were 4.9 and 4.6 per million age-related population, respectively. Incidence was higher for the Pacific coast and Guatemala City. The cause of CRF was undetermined in 43% of patients. Average time to progress to ESRD was 21.9 months; factors associated with progression were: older age, diagnosis of glomerulopathies, and advanced-stage CKD at consultation. CONCLUSIONS: Prevalence and incidence of ESRD in Guatemala are lower than in other countries. This may reflect poor access to diagnosis. Areas with higher incidence and large proportion of CKD of undetermined cause are compatible with other studies from the geographic subregion. Findings on progression to ESRD may reflect delayed referral.

    Medical evaluations of work capacity provide key information for decisions on a claimant's eligibility for disability benefits. In recent years, the evaluations have been increasingly criticized for low transparency and poor standardization. The International Classification of Functioning, Disability and Health (ICF) provides a comprehensive spectrum of categories for reporting functioning and its determinants in terms of impairments and contextual factors and could facilitate transparent and standardized documentation of medical evaluations of work capacity. However, the comprehensiveness of the ICF taxonomy in this particular context has not been empirically examined. In this study, we wanted to identify potential context-specific additions to the ICF for its application in medical evaluations of work capacity involving chronic widespread pain (CWP) and low back pain (LBP). A retrospective content analysis of Swiss medical reports was conducted by using the ICF for data coding. Concepts not appropriately classifiable with ICF categories were labeled as specification categories (i.e. context-specific additions) and were assigned to predefined specification areas (i.e. precision, coverage, personal factors, and broad concepts). Relevant specification categories for medical evaluations of work capacity involving CWP and LBP were determined by calculating their relative frequency across reports and setting a relevance threshold. Forty-three specification categories for CWP and fifty-two for LBP reports passed the threshold. In both groups of reports, precision was the most frequent specification area, followed by personal factors. The ICF taxonomy represents a universally applicable standard for reporting health and functioning information. However, when applying the ICF for comprehensive and transparent reporting in medical evaluations of work capacity involving CWP and LBP context-specific additions are needed. This is particularly true for the documentation of

    Mass shooting events are relatively underresearched, and most study comes from the United States. Despite significant international interest, little is known about other countries' experiences of these events. The current study examines Australian mass shooting incidents and offenders, with emphasis on mental illness, life strains, and offenders' life histories. Australia had 14 mass shootings between 1964 and 2014. Most offenders experienced acute life stressors and/or chronic strains leading up to the event; however, diagnosed mental illness was less commonly documented. These observations provide new information about mass shooting incidents and offenders, and can help to inform international policy development.

A randomised, controlled trial with concealed allocation. Patients were recruited from general practitioners, physiotherapists, or by advertising at a regional hospital in Norway. Men and women, aged 18-60 years, with chronic nonspecific LBP for 3 months or more, and pain score of 2 or more on a 0-10 numeric rating scale were included. Key exclusion criteria included radiating pain below the knee or neurological signs from nerve root compression, and former back surgery. Randomisation of 109 participants allocated 36 to CSE, 36 to SE, and 37 to GE. Patients in the three groups attended treatment once a week for 8 weeks, supervised by a physiotherapist. All were encouraged to stay active and received an information booklet with general information on LBP. The CSE were individualised according to protocols focusing on isolated activation of transversus abdominis during an abdominal drawing-in manoeuver in supine hook-lying position with ultrasound feedback. Written instructions to carry out the drawing-in exercise (10 × 10 seconds 2-3 times per day) at home were also provided. The SE maintained the lumbar spine stable in neutral position throughout a range of leg/arm positions and movements, using elastic bands attached to the pelvis to help the patient maintain a neutral spine position. The SE was performed for 40 minutes in a physiotherapy clinic. The GE group received generalised trunk strengthening and stretching exercises supervised by a physiotherapist at a fitness centre. Primary outcome was change in onset of the deep abdominal muscles in response to rapid shoulder flexion. 102 participants completed the study. No or small changes were found in onset after treatment. Baseline adjusted between

    Full Text Available Abstract Background In the past decade, a considerable amount of research has been carried out to evaluate the effectiveness of innovative low back pain (LBP interventions. Although some interventions proved to be effective, they are not always applied in daily practice. To successfully implement an innovative program it is important to identify barriers and facilitators in order to change practice routine. Because usual care is not directly aimed at return to work (RTW, we evaluated an integrated care program, combining a patient-directed and a workplace-directed intervention provided by a multidisciplinary team, including a clinical occupational physician to reduce occupational disability in chronic LBP patients. The aims of this study were to describe the feasibility of the implementation of the integrated care program, to assess the satisfaction and expectations of the involved stakeholders and to describe the needs for improvement of the program. Methods Eligible for this study were patients who had been on sick leave due to chronic LBP. Data were collected from the patients, their supervisors and the involved health care professionals, by means of questionnaires and structured charts, during 3-month follow-up. Implementation, satisfaction and expectations were investigated. Results Of the 40 patients who were eligible to participate in the integrated care program, 37 patients, their supervisors and the health care professionals actually participated in the intervention. Adherence to the integrated care program was in accordance with the protocol, and the patients, their supervisors and the health care professionals were (very satisfied with the program. The role of the clinical occupational physician was of additional value in the RTW process. Time-investment was the only barrier for implementation reported by the multidisciplinary team. Conclusion The implementation of this program will not be influenced by any flaws in its application

    Objectives To assess the feasibility of a trial to evaluate a trunk muscle training program augmented with neuromuscular electrical stimulation (TMT+NMES) for the rehabilitation of older adults with chronic LBP and to preliminarily investigate whether TMT+NMES could improve physical function and pain compared with a passive control intervention. Methods We conducted a single-blind, randomized feasibility trial. Patients aged 60-85 years were allocated to TMT+NMES (n=31) or a passive control intervention (n=33), consisting of passive treatments, i.e. heat, ultrasound and massage. Outcomes assessed 3-months and 6-months post-randomization included Timed Up and Go Test, gait speed, pain and LBP-related functional limitation. Results Feasibility was established by acceptable adherence (>/= 80%) and attrition (pain of greater than 2 points on a numeric pain rating scale during the course of the trial. But, only the TMT+NMES group had clinically important improvements in both performance-based and self-reported measures of function. In terms of the participants' global rating of functional improvement at 6-months, the TMT+NMES group improved by 73.9% and the passive control group improved by 56.7% compared to baseline. The between-group difference was 17.2% (95%CI: 5.87-28.60) in favor of TMT+NMES. Discussion It appears that a larger randomized trial investigating the efficacy of trunk muscle training augmented with NMES for the purpose of improving physical function in older adults with chronic LBP is warranted.

    2016-09-01

    Full Text Available Background: Strength and endurance tests are important for both clinical practice and research due to the key role they play in musculoskeletal function. In particular, deconditioning of the lumbar extensor musculature has been associated with low back pain (LBP. Due to the relationship between strength and absolute endurance, it is possible that trunk extension (TEX endurance tests could provide a proxy measure of isolated lumbar extension (ILEX strength and thus represent a simple, practical alternative to ILEX measurements. Though, the comparability of TEX endurance and ILEX strength is presently unclear and so the aim of the present study was to examine this relationship. Methods: Thirty eight healthy participants and nineteen participants with non-specific chronic LBP and no previous lumbar surgery participated in this cross-sectional study design. TEX endurance was measured using the Biering–Sorensen test. A maximal ILEX strength test was performed on the MedX lumbar-extension machine. Results: A Pearson’s correlation revealed no relationship between TEX endurance and ILEX strength in the combined group (r = 0.035, p = 0.793, the chronic LBP group (r = 0.120, p = 0.623 or the asymptomatic group (r = −0.060, p = 0.720. Conclusions: The results suggest that TEX is not a good indicator of ILEX and cannot be used to infer results regarding ILEX strength. However, a combination of TEX and ILEX interpreted together likely offers the greatest and most comprehensive information regarding lumbo-pelvic function during extension.

    2011-07-01

    Full Text Available Abstract Background Despite the large volume of research dedicated to understanding chronic low back pain (CLBP, patient outcomes remain modest while healthcare costs continue to rise, creating a major public health burden. Health literacy - the ability to seek, understand and utilise health information - has been identified as an important factor in the course of other chronic conditions and may be important in the aetiology of CLBP. Many of the currently available health literacy measurement tools are limited since they measure narrow aspects of health literacy. The Health Literacy Measurement Scale (HeLMS was developed recently to measure broader elements of health literacy. The aim of this study was to measure broad elements of health literacy among individuals with CLBP and without LBP using the HeLMS. Methods Thirty-six community-dwelling adults with CLBP and 44 with no history of LBP responded to the HeLMS. Individuals were recruited as part of a larger community-based spinal health study in Western Australia. Scores for the eight domains of the HeLMS as well as individual item responses were compared between the groups. Results HeLMS scores were similar between individuals with and without CLBP for seven of the eight health literacy domains (p > 0.05. However, compared to individuals with no history of LBP, those with CLBP had a significantly lower score in the domain 'Patient attitudes towards their health' (mean difference [95% CI]: 0.46 [0.11-0.82] and significantly lower scores for each of the individual items within this domain (p d = 0.47-0.65. Conclusions Although no differences were identified in HeLMS scores between the groups for seven of the health literacy domains, adults with CLBP reported greater difficulty in engaging in general positive health behaviours. This aspect of health literacy suggests that self-management support initiatives may benefit individuals with CLBP.

    2015-01-01

    This project is to demonstrate the capability to directly fabricate lightweight, high-resolution, grazing-incidence x-ray optics using a commercially available robotic polishing machine. Typical x-ray optics production at NASA Marshall Space Flight Center (MSFC) uses a replication process in which metal mirrors are electroformed on to figured and polished mandrels from which they are later removed. The attraction of this process is that multiple copies can be made from a single master. The drawback is that the replication process limits the angular resolution that can be attained. By directly fabricating each shell, errors inherent in the replication process are removed. The principal challenge now becomes how to support the mirror shell during all aspects of fabrication, including the necessary metrology to converge on the required mirror performance specifications. This program makes use of a Zeeko seven-axis computer-controlled polishing machine (see fig. 1) and supporting fabrication, metrology, and test equipment at MSFC. The overall development plan calls for proof-of-concept demonstration with relatively thick mirror shells (5-6 mm, fig. 2) which are straightforward to support and then a transition to much thinner shells (2-3 mm), which are an order of magnitude thinner than those used for Chandra. Both glass and metal substrates are being investigated. Currently, a thick glass shell is being figured. This has enabled experience to be gained with programming and operating the polishing machine without worrying about shell distortions or breakage. It has also allowed time for more complex support mechanisms for figuring/ polishing and metrology to be designed for the more challenging thinner shells. These are now in fabrication.

    Petterson, J.S.

    1988-06-01

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

    2010-07-01

    Full Text Available STUDY DESIGN: A cross-sectional study among health care providers working at one hospital. OBJECTIVE: To investigate the prevalence, the consequences and the risk factors associated with low back pain (LBP among hospital staff. MATERIALS AND METHODS: The study sample consisted of 931 health care providers who answered a pre-established questionnaire including 30 items in two languages. RESULTS: The cumulative life-prevalence of LBP was 72.5% and the yearly prevalence was 56.9%. Chronic LBP prevalence was noted 5.1% of the cases. Treatment was sought in 34.1% of LBP sufferers and 7.3% required sick leave or absence from work due to LBP. Risk factors associated with LBP were professional categories, bad body posture, lifting objects or patients and the increased levels of lifting, levels of job satisfaction and stressful job demands. CONCLUSION: There was a high prevalence of LBP among hospital staff, resulting in significant medical and socio-professional consequences. Many risk factors were identified that would necessitate multidisciplinary involvement to reduce the LBP incidence and related costs.

    2015-02-01

    Full Text Available Background:There is a basic assumption from the studies on hip–LBP relationship that suboptimal function of the hip might result in an alteration of the mechanics of the lumbopelvic region. Evidence is mounting to support the possibility that low back pain may be result of hip rotation deficits. The excessive or limited hip rotation range of motion could be a predisposing factor for low back dysfunction. Exercises and hip joint mobilization, individually found to be effective in chronic nonspecific low back pain with hip impairment. Hence, the purpose is to find the effect of hip joint mobilization with stretching exercises on intensity of pain and functional disability for subjects with chronic nonspecific low back pain associated with hip impairment. Method: An experimental study design selected 30 subjects with chronic low back pain associated with Hip impairment randomized 15 subjects each into Study and Control group. Control group received stretching exercises while Study group received hip joint mobilization with stretching exercises thrice a week for 3 weeks. Pain intensity was measured using Visual Analogue Scale and Functional disability was measured by Modified Oswestry Disability Index for LBP before and after 2 weeks of treatment. Results: There is statistically significant difference in improvement in means of VAS and Modified ODI when analyzed within the group. When the post-intervention means were compared between Study and Control group there is a statistically significant difference in means after 2 weeks of treatment. Conclusion: The present study concluded that the two weeks duration of combined hip joint mobilization with stretching exercises significantly effective on improving pain and functional disability than only stretching exercise regimen for chronic non-specific low back pain associated with Hip impairment.

    The aim of this study was to test the hypothesis that diabetes mellitus (DM) is associated with an increased prevalence of chronic low back pain (CLBP) in the general population. We analyzed data for 5106 adults (4591 without DM & 515 with diagnosed DM), who were part of the National Health and Nutrition Examination Survey (NHANES) from 2009 through 2010. Adults with DM were older (mean age 54.2years' vs. 42.1years), more likely to be obese (BMI>30, 69.5% vs. 33.3%), less educated (college or above 44.4% vs. 57.3%), had a lower annual income (low back pain (CLBP), and higher odds of CLBP after adjusting for LBP risk factors.

    Restless legs syndrome is a common sleep disorder, but there is a paucity of large cohort studies examining the association of restless legs syndrome with clinical outcomes, including all-cause mortality, incident coronary heart disease, stroke and chronic kidney disease. From a nationally representative prospective cohort of over 3 million US veterans [93% male, median follow-up time of 8.1 years (interquartile range: 7.0-8.5 years)] with baseline estimated glomerular filtration rate ≥ 60 mL min(-1) 1.73 m(-2), a propensity-matched cohort of 7392 patients was created, and the association between incident restless legs syndrome and the following was examined: (1) all-cause mortality; (2) incident coronary heart disease; (3) incident strokes; and (4) incident chronic kidney disease defined as estimated glomerular filtration rate restless legs syndrome-negative patients, incident restless legs syndrome was associated with 88% higher mortality risk [hazard ratio and 95% confidence interval: 1.88 (1.70-2.08)], and almost four times higher risk of coronary heart disease and stroke [hazard ratio: 3.97 (3.26-4.84) and 3.89 (3.07-4.94), respectively]. The risk of incident chronic kidney disease was also significantly higher in incident restless legs syndrome patients [hazard ratio: 3.17 (2.74-3.66)] compared with restless legs syndrome-negative counterparts. In this large and contemporary cohort of US veterans, incident restless legs syndrome was associated with higher risk of mortality, incident coronary heart disease, stroke and chronic kidney disease. © 2015 The Authors.

    Full Text Available Background: Low Back Pain (LBP is the most frequently reported musculoskeletal disorder in workers. This study was aimed to develop risk prediction model of low back pain that can be used to prevent the recurring low back pain attack.Methods: The study was case-control design based on the industrial community by using ergonomical approach. Total samples were 91 workers for cases and 91 workers for controls. Workers suffering for low back pain in the last 6 months served as cases, and those from the same age group and receiving the same amount of exposure without any symptoms of low back pain served as controls. Risk factors include socio-demographic factors, socio-ocupational factors, physical working environmental factors, non-physical environmental factors, and biomechanics factors. Receiver Operating Characreistics (ROC was used to describe relationship between true positive value (in vertical axis and false positive value (in horizontal axis in order to discover a risk predictive value of LBP.Results: The determinant risk factors for low back pain (LBP were bending work postures, waist rotation movement, manual lifting, unnatural work postures, those who had worked for more than 18 years, and irregular sport activities. By using ROC with 91.20% senstivity and 87.90% spesifi city, the calculated prediction value was 0.35. This is the cut-off point to discriminate workers with and without LBP. The risk predictors value of work-induced LBP calculated by linear equation of logistic regression varied between 0-11.25.Conclusion: The prediction model of work-induced LBP can be used for early detection of LBP to reduce the risk and prevent the recurrence of LBP.

    Full Text Available Objectives: To compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. Methods: The test was prospective and randomized control trial. The structure of trial was Urban Physical Medicine and Rehabilitation clinic. Participants was included of A total of 124 subjects with chronic low back pain (LBP and evidence of a degenerative and/or herniated inter-vertebral disk at 1 or more levels of the lumbar spine, who have not our exclusion criteria. There was A 4-week course of lumbar traction, prone or supine in case and control groups consecutively, consisting of six 30-minute sessions every other days, followed by four 30-minute sessions every 3 days. The numeric Visual pain rating scale and the Oswestry Disability Index (ODI were completed at pre-intervention and discharge (within 2 weeks of the last visit. Results: A total of 124 subjects completed the treatment protocol. We noted significant improvements for all post-intervention outcome scores when compared with pre-intervention scores (P<0.01. Also found significant difference between 2 groups in favor of prone traction (P<0.01 Discussion: Traction applied in the prone position for 4 weeks was associated with improvements in pain intensity and ODI scores at discharge, in a sample of patients with activity limiting LBP. However, because we lacked a reasonable long time follow-up, we cannot imply a long lasting relationship between the traction and outcome, and a long time follow-up is suggested.

    Full Text Available This study aimed to examine the effects of kinesiology taping (KT and different TRX suspension workouts on the amplitude of electromyographic (EMG activity in the core muscles among people with chronic low back pain (LBP. Each participant (total n=21 was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1 hamstring curl, (2 hip abduction in plank, (3 chest press, and (4 45-degree row. Right transversus abdominis/internal oblique (TrAIO, rectus abdominis (RA, external oblique (EO, and superficial lumbar multifidus (LMF activity was recorded with surface EMG and expressed as a percentage of the EMG amplitude recorded during a maximal voluntary isometric contraction of the respective muscles. Hip abduction in plank increased TrAIO, RA, and LMF EMG amplitude compared with other TRX positions (P0.05. Hip abduction in plank most effectively activated abdominal muscles, whereas the hamstring curl most effectively activated the paraspinal muscles. Applying KT conferred no immediate benefits in improving the core muscle activation during TRX training in adults with chronic LBP.

    Ivanna Avila Ribeiro

    Full Text Available Abstract Introduction : Chronic low back pain (LBP is characterized by daily lower back pain lasting more than three consecutive months. It may lead to functional disability and can be treated by several physical therapy techniques, including therapeutic exercise. The aim of this study was to investigate the effects of pilates and classical kinesiotherapy on the treatment of pain and functional disability in patients with chronic low back pain. Materials and methods : The study sample consisted of five patients with a diagnosis of chronic low back pain and a mean age of 32.4 ± 15.6 years. A Visual Analogue Scale (VAS was used for pain assessment, and the Oswestry Disability Index was used to assess functional disability at the beginning and at the end of the intervention. Patients were divided into two groups and received 20 individual sessions of therapeutic exercise at a frequency of two sessions per week. Group A was treated with classical kinesiotherapy and group B was treated with pilates exercises. Statistical analysis was performed using Wilcoxon's test. The significance level was set at 5%. Results : There was a significant reduction in pain (p = 043 and functional disability (p = 042 in both groups. We found no significant differences between the effects of pilates and classical kinesiotherapy on pain and functional disability. Conclusions : We conclude that, in the population studied here, both pilates and classical kinesiotherapy were effective in treating chronic low back pain symptoms, with no significant difference between them.

    2013-02-01

    Several treatment options have been proposed for chronic rhinosinusitis (CRS). Our purpose is to present a protocol/tool to treat patient symptoms, which is initially independent of assessment for presence of CRS. This protocol is called the Rational Patient Experiment (RPE), and its concept is largely based on the fact that CRS is overrepresented in incidence based on surveys, because symptoms of CRS are nonspecific and overlap multiple other disorders. Patients whose symptoms persist, despite the RPE, require further objective assessment of CRS with endoscopy and computed tomography. This review outlines the RPE and the evidence base for observation versus treatment with saline washes, steroids, or antibiotics.

    1977-11-01

    A group of patients between 35 and 65 years old with chronic prostatitis were examined for the presence of Becherew's disease. In this connection the New York and Roman criterions for morbus Bechterew were applied. There were found one ankyosing spondylarthritis, one ankylosis of the sacroiliac joint, and 11 times a tentative sacroileitis were stated. Altogether the proved and tentative findings were only 3.68 per cent of all examinations. In our countries the morbus Bechterew is found in 0,21 per cent of the normal population. So the protion of the Bechterew's disease in patients with chronic prostatitis is indeed a little higher than average, but not so frequent as often pretended in recent times. After a second series 58 patients being treated because of Bechterew's disease of different stages and different terms were examined for the possibility of a simultaneously elapsing chronic prostatitis. A chronic prostatitis was found in 38 per cent of these patients which correspondents to the incidence published in literature for the medium-age manhood. Nobody of the test persons had complaints on the part of the urologenital tract.

    Background. Due to specific war and post-war situation in Balkan region, differences in the number, type, development, biological course, treatment of malignant tumours and its outcome are possible. In order to perceive the situation realistically, it is necessary to gather continuously exact data about malignant tumours and compare them with the data from other European and world countries.The aim of the study was to collect and analyse the data on cancer incidence in the region of Sarajevo city, which represents a symbol of difficult times in the recent past, and to compare it to the incidence in the neighbouring countries. Patients and methods. Data on all newly diagnosed cancer cases, permanent residents of Sarajevo Canton, in the years 1999 and 2000 were collected. Crude incidence rate has been calculated according to the years observed, gender and localizations of the disease The data were compared to the cancer registries of Slovenia and Croatia and were observed in the light of specific local situation. Results. The crude cancer incidence of all sites but skin was the highest in both years and by both genders in Croatia. The incidence of the most common tumours (lung and breast cancer) was similar in all three countries. The differences in the incidence between both genders in the Sarajevo canton were registered in laryngeal and urinary bladder cancer, as well as in bone and cartilage sarcoma. Cervical cancer had extremely high incidence and was high up on the incidence list in the Sarajevo canton, which correlates with the data in developing countries. The incidence of other tumours in the post-war period is reaching expected numbers. Conclusions. It is difficult to identify whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city of Sarajevo or some other factor influenced the cancer incidence among exposed population. The prevalence of smoking in the whole region is extremely high, in Bosnia and

    Periodic cancer incidence estimates of Spain from all existing population-based cancer registries at any given time are required. The objective of this study was to present the current situation of cancer incidence in Spain. The Spanish Network of Cancer Registries (REDECAN) estimated the numbers of new cancer cases occurred in Spain in 2015 by applying the incidence-mortality ratios method. In the calculus, incidence data from population-based cancer registries and mortality data of all Spain were used. In 2015, nearly a quarter of a million new invasive cancer cases were diagnosed in Spain, almost 149,000 in men (60.0%) and 99,000 in women. Globally, the five most common cancers were those of colon-rectum, prostate, lung, breast and urinary bladder. By gender, the four most common cancers in men were those of prostate (22.4%), colon-rectum (16.6%), lung (15.1%) and urinary bladder (11.7%). In women, the most common ones were those of breast (28.0%), colon-rectum (16.9%), corpus uteri (6.2%) and lung (6.0%). In recent years, cancer incidence in men seems to have stabilized due to the fact that the decrease in tobacco-related cancers compensates for the increase in other types of cancer like those of colon and prostate. In women, despite the stabilization of breast cancer incidence, increased incidence is due, above all, to the rise of colorectal and tobacco-related cancers. To reduce these incident cancer cases, improvement of smoking control policies and extension of colorectal cancer screening should be the two priorities in cancer prevention for the next years.

  10. Cyber Incidents Involving Control Systems

    The Analysis Function of the US-CERT Control Systems Security Center (CSSC) at the Idaho National Laboratory (INL) has prepared this report to document cyber security incidents for use by the CSSC. The description and analysis of incidents reported herein support three CSSC tasks: establishing a business case; increasing security awareness and private and corporate participation related to enhanced cyber security of control systems; and providing informational material to support model development and prioritize activities for CSSC. The stated mission of CSSC is to reduce vulnerability of critical infrastructure to cyber attack on control systems. As stated in the Incident Management Tool Requirements (August 2005) ''Vulnerability reduction is promoted by risk analysis that tracks actual risk, emphasizes high risk, determines risk reduction as a function of countermeasures, tracks increase of risk due to external influence, and measures success of the vulnerability reduction program''. Process control and Supervisory Control and Data Acquisition (SCADA) systems, with their reliance on proprietary networks and hardware, have long been considered immune to the network attacks that have wreaked so much havoc on corporate information systems. New research indicates this confidence is misplaced--the move to open standards such as Ethernet, Transmission Control Protocol/Internet Protocol, and Web technologies is allowing hackers to take advantage of the control industry's unawareness. Much of the available information about cyber incidents represents a characterization as opposed to an analysis of events. The lack of good analyses reflects an overall weakness in reporting requirements as well as the fact that to date there have been very few serious cyber attacks on control systems. Most companies prefer not to share cyber attack incident data because of potential financial repercussions. Uniform reporting requirements will do much to make this

    The aim of this study was to evaluate the effect of chronic disease(s) on work productivity. Using the Health & Work Performance Questionnaire, information was collected from 516 workers on chronic disease status and work productivity. Propensity-score matching was performed to identify matched-pairs of workers. In the propensity-score matched sample, workers with chronic diseases were more likely to have increased absenteeism and presenteeism rates, 6.34 and 2.36 times the rates if no chronic diseases, respectively. In addition, they had greater odds for getting negative critical work incidents and less odds for positive incidents than none or balanced status. Multimorbidity showed more significant increase in absenteeism and presenteeism rates, as well as increased odds for excess negative critical work incidents. Chronic disease(s) can significantly reduce work productivity by increasing absenteeism, presenteeism, and net negative critical incidents.

    The objective of the study was to identify commonalities among the International Classification of Functioning, Disability and Health (ICF) Core Sets of osteoarthritis (OA), osteoporosis (OP), low back pain (LBP), rheumatoid arthritis (RA) and chronic widespread pain (CWP). The aim is to identify relevant categories for the development of a tentative ICF Core Set for musculoskeletal and pain conditions. The ICF categories common to the five musculoskeletal and pain conditions in the Brief and Comprehensive ICF Core Sets were identified in three steps. In a first step, the commonalities across the Brief and Comprehensive ICF Core Sets for these conditions were examined. In a second and third step, we analysed the increase in commonalities when iteratively excluding one or two of the five conditions. In the first step, 29 common categories out of the total number of 120 categories were identified across the Comprehensive ICF Core Sets of all musculoskeletal and pain conditions, primarily in the component activities and participation. In the second and third step, we found that the exclusion of CWP across the Comprehensive ICF Core Sets increased the commonalities of the remaining four musculoskeletal conditions in a maximum of ten additional categories. The Brief ICF Core Sets of all musculoskeletal and pain conditions contain four common categories out of a total number of 62 categories. The iterative exclusion of a singular condition did not significantly increase the commonalities in the remaining. Based on our analysis, it seems possible to develop a tentative Comprehensive ICF Core Set across a number of musculoskeletal conditions including LBP, OA, OP and RA. However, the profile of functioning in people with CWP differs considerably and should not be further considered for a common ICF Core Set.

    We describe the mixed-methods (qualitative and quantitative) development and preliminary validation of the Patient Assessment for Low Back Pain-Symptoms (PAL-S), a patient-reported outcome measure for use in chronic low back pain (cLBP) clinical trials. Qualitative methods (concept elicitation and cognitive interviews) were used to identify and refine symptom concepts and quantitative methods (classical test theory and Rasch measurement theory) were used to evaluate item- and scale-level performance of the measure using an iterative approach. Patients with cLBP participated in concept elicitation interviews (N = 43), cognitive interviews (N = 38), and interview-based assessment of paper-to-electronic mode equivalence (N = 8). A web-based sample of patients with self-reported cLBP participated in quantitative studies to evaluate preliminary (N = 598) and revised (n = 401) drafts and a physician-diagnosed cohort of patients with cLBP (N = 45) participated in preliminary validation of the measure. The PAL-S contained 14 items describing symptoms (overall pain, sharp, prickling, sensitive, tender, radiating, shocking, shooting, burning, squeezing, muscle spasms, throbbing, aching, and stiffness). Item-level performance, scale structure, and scoring seemed to be appropriate. One-week test-retest reproducibility was acceptable (intraclass correlation coefficient 0.81 [95% confidence interval, 0.61-0.91]). Convergent validity was demonstrated with total score and MOS-36 Bodily Pain (Pearson correlation -0.79), Neuropathic Pain Symptom Inventory (0.73), Roland-Morris Disability Questionnaire (0.67), and MOS-36 Physical Functioning (-0.65). Individual item scores and total score discriminated between numeric rating scale tertile groups and painDETECT categories. Respondent interpretation of paper and electronic administration modes was equivalent. The PAL-S has demonstrated content validity and is potentially useful to assess treatment benefit in cLBP clinical trials

    Full Text Available Alcoholic pancreatitis continues to stir up controversy. One of the most debated points is whether from onset it is a chronic disease or whether it progresses to a chronic form after repeated episodes of acute pancreatitis. Histological studies on patients with alcoholic pancreatitis have shown that the disease is chronic from onset and that alcoholic acute pancreatitis occurs in a pancreas already damaged by chronic lesions. Genetic factors may also play a role in the pathogenesis of alcoholic disease. The incidence of chronic alcoholic pancreatitis seems to have decreased in the last twenty years. Finally, recent therapeutic studies which have shown medical or surgical approaches capable of reducing the pain episodes in chronic pancreatitis patients will be described.

    A 50-year-old woman with nonallergic rhinitis, asthma, and aspirin intolerance presented with worsening symptoms of nasal congestion, purulent drainage, and anosmia. Nasal polyps were visualized on anterior rhinoscopy, and there was evidence of chronic rhinosinusitis (CRS) on imaging studies during work-up for another medical condition. Over a 2-year period she had numerous bouts of acute exacerbations of CRS which required multiple courses of antibiotics; however, she was unwilling to undergo surgery to reduce polyp burden. She successfully underwent aspirin desensitization and experienced partial relief of symptoms with daily aspirin ingestion. Nasal obstruction is a common symptom that can result from multiple causes, including mucosal disorders (eg, allergic and nonallergic rhinitis, rhinosinusitis, sarcoid) and structural disorders (eg, nasal septal deviation, tumors, mucoceles). The various causes and work-up for nasal obstruction are discussed with emphasis placed on CRS, which is a prevalent disease characterized by inflammation of the nose and paranasal sinuses for a duration of >12 weeks. The different subtypes of CRS, including CRS with and without nasal polyps, allergic fungal rhinosinusitis, and aspirin-exacerbated respiratory disease, are discussed along with pathogenesis, diagnosis, and treatment options.

    Kennedy, M P

    2012-02-03

    SETTING: The Southwest of Ireland (Counties Cork and Kerry) 1987-2000, average population 549,500. OBJECTIVE: Nontuberculous mycobacteria (NTM) cause significant morbidity worldwide and the study of epidemiology and characteristics helps in their prevention and treatment. This study was performed to determine the incidence of NTM disease in comparison to Mycobacterium tuberculosis (M. tuberculosis) and Mycobacterium bovis (M. bovis) in Southwest Ireland, over the above time period. DESIGN: A retrospective study was carried out in all human isolates of NTM, M. tuberculosis and M. bovis between 1987 and 2000, in the Southwest Region of Ireland. RESULTS: The mean incidence of NTM (0.4\\/100,000 population) has risen since 1995, principally of pulmonary Mycobacterium avium intracellulare complex (MAC). The annual incidence of M. tuberculosis in humans over 14 years in the same region was 971\\/100,000 population with a significant reduction since 1994 and M. bovis remained constant at 0.5\\/100,000 population. CONCLUSION: The increasing incidence of disease causing NTM noted in Southwest Ireland reflects global data and is surmised to be due to an ageing population, increased incidence related to chronic fibrotic lung disease, and environmental mycobacterial factors.

    Purpose Data on international variation in breast cancer incidence may help to identify additional risk factors. Substantially lower breast cancer rates in Asia than in North America and Western Europe are established, but differences within Asia have been largely ignored despite heterogeneity in lifestyles and environments. Mongolia’s breast cancer experience is of interest because of its shared genetics but vastly different diet compared with other parts of Asia. Methods Age-standardized breast cancer incidence and mortality rates obtained from the International Association of Cancer Registries are presented for several Asian countries. Mongolian incidence rates obtained from its cancer registry describe incidence within the country. Results Breast cancer incidence in Mongolia (age standardized 8.0/100,000) is almost a third of rates in China (21.6/100,000), and over five times that of Japan (42.7/100,000) and Russia (43.2/100,000). Rates within Mongolia appear to have increased slightly over the last decade and are higher in urban than rural areas (annual percentage increase of age-standardized rates from 1998 to 2005 was 3.60 and 2.57%, respectively). The increase in breast cancer incidence with age plateaus at menopause, as in other Asian populations. Conclusions Mongolia’s low breast cancer incidence is of particular interest because of their unusual diet (primarily red meat and dairy) compared with other Asian countries. More intensive study of potential dietary, reproductive and lifestyle factors in Mongolia with comparison to other Asian populations may provide more clarity in what drives the international breast cancer rate differences.

    Growing public health concern exists over the incidence of chronic traumatic brain injury (TBI) in athletes participating in contact sports. Chronic TBI represents a spectrum of disorders associated with long-term consequences of single or repetitive TBI and includes chronic traumatic encephalopathy (CTE), chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologists should be familiar with the different types of chronic TBI and their diagnostic criteria. CTE is the most severe chronic TBI and represents the neurologic consequences of repetitive mild TBI. It is particularly noted among boxers and football players. CTE presents with behavioral, cognitive, and motor symptoms, and can only be definitively diagnosed postmortem. Chronic postconcussion syndrome is defined as postconcussion symptoms that last longer than 1 year and do not appear to resolve; it may develop after a single concussive event. Chronic neurocognitive impairment is an all-encompassing clinical term denoting long-term neurologic sequelae secondary to sports-related trauma and can present either within the postconcussion syndrome or years after a symptom-free interval. This article discusses the diagnostic evaluation of chronic TBI, including clinical history, neurologic examination, neuropsychological testing, neuroimaging, and laboratory testing, as well as the distinctions between CTE, chronic postconcussion syndrome, and chronic neurocognitive impairment. Neurologic impairment among athletes exposed to repetitive brain injury appears to be a real phenomenon. Because CTE has no established treatment, prevention is of paramount importance for athletes participating in contact sports.

    In order to evaluate the predictive effect of non-invasive preoperative imaging methods on surgical outcomes of lumbar fusion for patients with degenerative disc disease (DDD) and refractory chronic axial low back pain (LBP), the authors conducted a retrospective review of 45 patients with DDD and refractory LBP submitted to anterior lumbar interbody fusion (ALIF) at a single center from 2007 to 2010. Surgical outcomes - as measured by Visual Analog Scale (VAS/back pain) and Oswestry Disability Index (ODI) - were evaluated pre-operatively and at 6 weeks, 3 months, 6 months, and 1 year post-operatively. Linear mixed-effects models were generated in order to identify possible preoperative imaging characteristics (including bone scan/99mTc scintigraphy increased endplate uptake, Modic endplate changes, and disc degeneration graded according to Pfirrmann classification) which may be predictive of long-term surgical outcomes . After controlling for confounders, a combined score, the Lumbar Fusion Outcome Score (LUFOS), was developed. The LUFOS grading system was able to stratify patients in two general groups (Non-surgical: LUFOS 0 and 1; Surgical: LUFOS 2 and 3) that presented significantly different surgical outcomes in terms of estimated marginal means of VAS/back pain (p = 0.001) and ODI (p = 0.006) beginning at 3 months and continuing up to 1 year of follow-up. In conclusion,  LUFOS has been devised as a new practical and surgically oriented grading system based on simple key parameters from non-invasive preoperative imaging exams (magnetic resonance imaging/MRI and bone scan/99mTc scintigraphy) which has been shown to be highly predictive of surgical outcomes of patients undergoing lumbar fusion for treatment for refractory chronic axial LBP.

    2008-01-01

    SUMMARY A prospective survey on scabies in Ghent, Belgium was performed in 2004. Sixty-four individual cases were reported, corresponding to a crude incidence rate of 28/100 000 inhabitants. The incidence was higher in the elderly (51/100 000 in persons aged >75 years) and a higher incidence was also found in immigrants (88/100 000). More than 40% of the registered scabies patients had symptoms for more than 4 weeks at the time of presentation. In 54% of the consultations, the patient had already consulted a physician for his/her skin problem. Of this group, 44% had not yet received any scabicidal treatment, indicating that scabies was not yet diagnosed or that an inappropriate treatment was prescribed. The observations suggest that the diagnosis and/or treatment of scabies in this region can still be improved. PMID:17506916

To evaluate the clinical significance of PDI identified according to clinical criterions. An observational crossover study. Clutat Vella health district (City of Barcelona). Using information of Consejo General de Colegios Oficiales de Farmaceuticos databases and the chronic prescriptions database of the primary care centers, computerized drug-interaction system have been developed for detection of PDI in patients. A panel of primary care physicians and clinical pharmacists developed criteria that were used to evaluate the clinical significance of PDI. 9840 Cards of Authorized Prescription (CAP) were analyzed, 36108 medicaments and 42877 drugs. A total of 2140 patients were involved for a total of 3406 PDI, 21.75% of patients with CAP. Clinical signification for the panel was found in 40.07% of these 3406 PIF; 3.78% were suggest to avoid the association drugs. The incidence of PDI with clinical signification are lower than other studies of the literature; it suggest a appropriate knowledge of drug prescription. The application of computerized program make much more easy the detection of adverse drug interactions in chronic prescription.

    In chronic viral hepatitis the histopathological exam can reveal the presence of liver iron deposits in 10 to 73% of patients. Iron deposits are usually found in Kupffer cells, in endothelial cells and portal macrophages, and extremely rarely in hepatocytes. To evaluate the incidence of hepatic hemosiderosis in chronic viral hepatitis. 549 morphopathological features of liver biopsy specimens performed in the Gastroenterology and Hepatology Institute IaSi, between January 1 2003 and December 31 2007 have been analyzed. Semiquantitative assessment of the degree of hepatic iron overload was performed and the localization of haemosiderin deposits: at the level of hepatocytes, the reticuloendothelial system or mixedly. The same anatomopathologist examined the blades and interpreted the results. The medium age of patients who underwent liver biopsy was 45.08 years +/- 10.045. Positive iron staining was found in 22.8% of cases, more frequently in males (31%), and in 91.82% of cases iron deposits were grade 1-2. The association of alcoholic etiology did not influence the incidence of hemosiderosis: 23% in patients with hepatitis and no ethanol exposure vs 25% in cases of strictly viral etiology. Deposits of haemosiderin were more frequent in viral hepatitis B (38.6%) than in viral hepatitis C (26.9%). In 34% of cases stainable iron was found only in reticuloendothelial system and in 46% of cases both in Kupffer cells and hepatocytes. Almost a quarter of chronic viral hepatitis cases are associated with liver deposits of haemosiderin, with features of secondary iron overload (deposits localized in the mesenchymal areas or mixedly). There is a higher risk of hemosiderosis in men, especially for those between 30 and 50. Liver iron overload levels in chronic viral hepatitis are, in most cases, low or medium, and the association with an alcoholic etiology does not influence the incidence of hemosiderosis in chronic viral hepatitis.

They presented with disphagia and food impaction and endoscopic findings included multiple concentric rings (pseudo-trachea pattern) and friable mucosa. All of them had mucosal eosinophil counts higher than 20 eosinophils/high-powered field and were given corticosteroids, either topic or systemic (one case) with therapeutic success. The diagnosis of Eosinophilic Esophagitis must be considered in presence of disphagia, food impaction or gastroesophageal reflux symptoms refractory to treatment. Endoscopic evaluation may be normal and the diagnosis is based on histological findings, making biopsy mandatory whenever clinically suspected. The increasing incidence of the last years associated with the high recurrence rate will lead to future prevalence increased both in child and adulthood.

    Original data reported a potential increased incidence of thyroid cancer surrounding the Three Mile Island (TMI) nuclear facility. A causal link to the accident, however, was indeterminate. Our objective was to determine if data 30 years later will change original conclusions, explore thyroid cancer incidence rates near nuclear power plants, and better understand effects of chronic low level radiation. Retrospective cross-sectional study. Retrospective data for specific Pennsylvania counties were provided by the Pennsylvania Cancer Registry Dataset for thyroid cancer using the Epidemiological Query and Mapping System search engine. Our study examines thyroid cancer incidence from 1985 through 2009 analyzed by year, county, and age. Thirty years after the TMI accident, an increased incidence of thyroid cancer is seen in counties south of TMI and in high-risk age groups. The average incidence rates from 1990 through 2009 were greater than expected in York, Lancaster, Adams, and Chester Counties. Thyroid cancer incidence since the TMI accident was greater than expected in the counties analyzed when compared to local and national population growth. This supports a link to chronic low level radiation exposure and thyroid cancer development. Despite these findings, a direct correlation to the accident remains uncertain as incidence rates may coincide with other factors, and original data were limited. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    Full Text Available Epilepsy is a chronic condition due to cerebral function disorders. Epilepsy occurs as a common complication of many neurological disorders such as cerebral palsy (CP that can affect further brain damage especially if they are with prolonged seizure. The incidence of epilepsy among patients with CP varies between 25-35%. The high incidence of epilepsy among patients with CP suggests that this disorder has common or related origins. We carried out the retrospective study to determine incidence of epilepsy among patients with CP registered within July 1988 to June 1998 in YPAC Medan and to determine whether the incidence of epilepsy differed according to type of CP. Data were compiled from medical records, including name, sex, parity, mothers age, prenatal, perinatal, and postnatal history, and EEG results. Data were analyzed using statistical computer program and its significance was evaluated by chi square test at p < 0,05. There were 67 cases with CP, 53 cases spastic CP, 13 cases mixed CP and one case dyskinetic CP. Of the 67 cases CP, 47,8% male, 52,2% female and mean age 50,3 (SD 36,9 months. There were 25 (37,3% patients CP associated with epilepsy, 72% general seizures, 20% partial seizures, and 8% infantile spasms. The incidence of epilepsy was significant different among patients with CP associated with type of CP and gestasional age, p < 0,05. We concluded that incidence of epilepsy among patients with CP in YPAC Medan was 37,3% and significantly different among patients with CP according to type CP and gestasional age.

    Hypoparathyroidism is a rare endocrine disorder whose incidence and prevalence have not been well defined. This study aimed to 1) estimate the number of insured adult patients with hypoparathyroidism in the United States and 2) obtain physician assessment of disease severity and chronicity. Prevalence was estimated through calculation of diagnoses of hypoparathyroidism in a large proprietary health plan claims database over a 12-month period from October 2007 through September 2008 and projected to the US insured population. Incidence was also calculated from the same database by determining the proportion of total neck surgeries resulting in either transient (≤6 months) or chronic (>6 months) hypoparathyroidism. A physician primary market research study was conducted to assess disease severity and determine the percentage of new nonsurgical patients with hypoparathyroidism. Incidence data were entered into an epidemiologic model to derive an estimate of prevalence. The diagnosis-based prevalence approach estimated 58,793 insured patients with chronic hypoparathyroidism in the United States. The surgical-based incidence approach yielded 117,342 relevant surgeries resulting in 8901 cases over 12 months. Overall, 7.6% of surgeries resulted in hypoparathyroidism (75% transient, 25% chronic). The prevalence of chronic hypoparathyroidism among insured patients included in the surgical database was estimated to be 58,625. The physician survey found that 75% of cases treated over the past 12 months were reported due to surgery and, among all thyroidectomies and parathyroidectomies and neck dissections performed in a year, 26% resulted in transient hypoparathyroidism and 5% progressed to a chronic state. In conclusion, the two claims-based methods yielded similar estimates of the number of insured patients with chronic hypoparathyroidism in the United States (~58,700). The physician survey was consistent with those calculations and confirmed the burden imposed by

    Diabetes is accompanied with a chronic low-grade inflammation, which may in part be mediated by endotoxins derived from Gram-negative bacteria. We investigated in a population-based cohort whether endotoxemia is associated with clinically incident diabetes. The serum endotoxin activity was measured by limulus assay from the FINRISK97 cohort comprising 7,169 subjects aged 25-74 years and followed up for 10 years. Both the subjects with prevalent diabetes (n = 537) and those with incident diabetes (n = 462) had higher endotoxin activity than the nondiabetic individuals (P endotoxemia with an increased risk of incident diabetes was independent of the metabolic syndrome as defined either by the National Cholesterol Educational Program-Adult Treatment Panel III or the International Diabetes Federation. Endotoxin activity was linearly related (P metabolic syndrome. Both prevalent and incident diabetes were associated with endotoxemia, which may link metabolic disorders to inflammation. The results suggest that microbes play a role in the pathogenesis of diabetes.

    Evaluation of a partial scram incident occurred at the Fast Breeder Test Reactor at Kalpakkam was carried out. Based on the observations of the experiments it was ascertained that the nonpersistant order was due to superimposed noise component on the channel that was close to the threshold and had resulted in intermittent supply to electro-magnetic (EM) coils. Owing to a larger discharge time and a smaller charge time, the EM coils got progressively discharged. It was confirmed that during the incident, partial scram took place since the charging and discharging patterns of the EM coils are dissimilar and EM coils of rods A, E and F had discharged faster than others for noise component of a particular duty cycle. However, nonlatching of scram order was because of the fact that noise pulse duration was less than latching time. (author)

  20. Dissociative Tendencies and Traffic Incidents

    2012-01-01

    Full Text Available This paper analyses the relationship between dissociative experiences and road traffic incidents (crashes and traffic tickets in drivers (n=295 from Mar del Plata (Argentina city. A self-report questionnaire was applied to assess traffic crash involvement and sociodemographic variables. Dissociative tendencies were assessed by a modified version of the DES scale. To examine differences in DES scores tests of the difference of means were applied. Drivers who reported to be previously involved in traffic incidents obtained higher puntuations in the dissociative experiences scale than drivers who did not report such events. This result is observed for the total scale and for the three sub-scales (absorption, amnesia and depersonalization. However, differences appeared mainly for minor damage collisions. Further studies are needed to evaluate the role of dissociative tendencies as a risk factor in road traffic safety.

    Cancer is regarded as abnormal cellular multiplication; it is not controlled by the organism, and its cells present a differentiated DNA. Initially, the disease does not show clinical signs, but it can be diagnosed by laboratory examinations. When tumors are present in the maxillofacial area, the carrier can lose structures in this area, resulting to the carrier's social environment exclusion. This article aims to show incidences and causes of malignant neoplasias in the maxillofacial area.

    This study reports about the frequent incidence of Crohn's disease in four families. This evidence in confirmed by literature. Relatives of patients with Crohn's disease are ten times more likely to suffer from that disease than those of healthy families. Familial accumulation of Crohn's disease can possibly be explained by genetic factors. Other factors like autoimmunological processes, infections, overnutrition and deficient composition of alimentation with refined carbohydrates might start Crohn's diseases in these families.

    Objective: To determine the incidence of respiratory distress syndrome (RDS) in hospital born babies. Subjects and Methods: All live born infants delivered at the hospital and who fulfilled the diagnostic criteria of respiratory distress syndrome (RDS) were included in the study. Results: Ninety-four neonates developed RDS. Out of these, 88 (93.61%) were preterm and 06 (6.38%) were term infants. There was a male preponderance (65.95%). RDS was documented in 1.72% of total live births. 37.28% of preterm and 0.11% of term neonates born at the hospital. The incidence of RDS was 100% at 26 or less weeks of gestation, 57.14% at 32 weeks, and 3.70% at 36 weeks. The mortality with RDS was 41 (43.61%). Conclusion: RDS is the commonest cause of respiratory distress in the newborn, particularly, in preterm infants. It carries a high mortality rate and the incidence is more than that documented in the Western world. (author)

    Skin cancer is the most frequent cancer related to ultraviolet radiation. The aim was to estimate the incidence of skin cancer type, melanoma and non-melanoma in Zacatecas, Mexico. An epidemiological study was carried out during the period from 2008 to 2012. The data were obtained from the Instituto Mexicano del Seguro Social (IMSS), Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE), Secretaría de Salud de Zacatecas (SSZ) and a private source, the Centro Médico Alameda. The incidence and the global prevalence were estimated. We studied 958 skin cancer cases, histopathologically confirmed. The cases were distributed as: 63.6 % basal cell carcinomas, 25.8 % squamous cell carcinomas, and 10.6 % melanoma. Significantly higher proportions were observed in women in the basal cell carcinomas (60.4 %) and squamous cell carcinomas (53.4 %). However, in the case of melanoma, the major proportion was observed in men (55.9 %). The more frequent skin cancer location was the face and for basal cell carcinoma was the nose (53 %); for squamous cell carcinomas were the lips (36 %), and for melanoma it was also the nose (40 %). The skin cancer incidence was estimated in 20 cases for each 100 000 inhabitants. Linear regression analysis showed that the skin cancer is increasing at an annual rate of 10.5 %. The anatomical location indicates that solar UV radiation is a risk factor, since the face is the zone with major exposure to solar radiation.

    An ability to assess longitudinal changes in health status is crucial for the outcome measures used in treatment efficacy trials. The aim of this study was to verify the responsiveness of the Italian versions of the Oswestry Disability Index (ODI) and the Roland Morris Disability Questionnaire (RMDQ) in subjects with subacute or chronic low back pain (LBP). At the beginning and end of an 8 week rehabilitation programme, 179 patients completed a booklet containing the ODI, the RMDQ, a 0-10 numerical rating scale (NRS), and the 36-item Short-Form Health Survey (SF-36). A global perception of change scale was also completed at the end of the programme, and collapsed to produce a dichotomous outcome (i.e. improved vs. not improved). Responsiveness was assessed by means of distribution methods [minimum detectable change (MDC); effect size (ES); standardised response mean (SRM)] and anchor-based methods (ROC curves). The MDC for the ODI and RMDQ was, respectively, 13.67 and 4.87; the ES was 0.53 and 0.68; and the SRM was 0.80 and 0.81. ROC analysis revealed an area under the curve of 0.71 for the ODI and 0.64 for the RMDQ, thus indicating discriminating capacity; the best cut-off point for the dichotomous outcome was 9.5 for the ODI (sensitivity 76% and specificity 63%) and 2.5 for the RMDQ (sensitivity 62% and specificity 55%). These estimates were comparable between the subacute and chronic subjects. Both the ODI and the RMDQ moderately correlated with the SF-36 and NRS (Spearman's and Pearson's correlation coefficients of >0.30). The Italian ODI and RMDQ proved to be sensitive in detecting clinical changes after conservative treatment for subacute and chronic LBP. Our findings are consistent with those published in the literature, thus allowing cross-cultural comparisons and stimulating cross-national studies.

    Study Design A prospective cohort study. Background Motor control dysfunctions have been commonly reported in patients with chronic nonspecific low back pain (LBP). Physical therapists need clinical tools with adequate psychometric properties to assess such patients in clinical practice. The deep muscle contraction (DMC) scale is a clinical rating scale for assessing patients' ability to voluntarily contract deep abdominal muscles. Objectives To investigate the intrarater reliability, floor and ceiling effects, internal and external responsiveness, and correlation analysis (with ultrasound measures) of the DMC scale in patients with chronic nonspecific LBP undergoing a lumbar stabilization exercise program. Methods Sixty-two patients with chronic nonspecific LBP were included. At baseline, self-report questionnaires were administered to patients and a trained assessor evaluated abdominal muscle recruitment with the DMC scale and ultrasound imaging. Four ratios of the change in abdominal muscle thickness between the resting and contracted states were calculated through the ultrasound measures. After 1 week, the same ultrasound measures and DMC scale were collected again for the reliability analysis. The proportions of patients with the lowest and highest scores on the DMC scale were calculated to investigate floor and ceiling effects. All patients underwent a lumbar stabilization program, administered twice a week for 8 weeks. After the treatment period, all measures were collected again, with the addition of the global perceived effect scale, to assess the internal and external responsiveness of the measures. Correlation coefficients between ultrasound ratios and DMC scale total and subscale scores were also calculated. Results The intrarater reliability of the DMC scale and the 4 ratios of abdominal muscle thickness varied from moderate to excellent. The DMC scale showed no floor or ceiling effects. Results for internal responsiveness of the DMC scale showed large

    The information on incidence of the facial nerve canal dehiscence in chronic otitis media is important for surgeons. The purpose of this study is to disclose the histopathologic findings of facial nerve canal dehiscence in human temporal bones with chronic otitis media. We divided the human temporal bones into two groups (age 4 years, and under 4 years of age). We evaluated the incidence and the area of the facial nerve canal dehiscence in chronic otitis media under light microscopy. Age-matched normal control temporal bones were also examined. In the age group of 4 years, 68.9 % of temporal bones with chronic otitis media and 71.9 % of controls had the facial nerve canal dehiscence. There was no significant difference between them (P = 0.61). The area of the dehiscence in temporal bones with chronic otitis media was not statistically different from controls (P = 0.53). In the age group under 4 years, 88.2 % of temporal bones with chronic otitis media and 76.5 % of controls had the dehiscence. No significant difference was found between them (P = 0.66). The area of the dehiscence in temporal bones with chronic otitis media was not statistically different from controls in the age group under 4 years (P = 0.43). In chronic otitis media, the incidence of facial nerve canal dehiscence was high and was not statistically different from controls. These results suggest that there is no association between chronic otitis media and the presence of facial nerve canal dehiscence.

    Spinal manipulation (SM) is used commonly for treating low back pain (LBP). Spinal stiffness is routinely assessed by clinicians performing SM. Flexion-relaxation ratio (FRR) was shown to distinguish between LBP and healthy populations. The primary objective of this study was to examine the association of these two physiological variables with patient-reported pain intensity and disability in adults with chronic LBP (>12 weeks) receiving SM. A single-arm trial provided 12 sessions of side-lying thrust SM in the lumbosacral region over 6 weeks. Inclusion criteria included 21-65 years old, Roland-Morris Disability Questionnaire (RMDQ) score ≥ 6 and numerical pain rating score ≥ 2. Spinal stiffness and FRR were assessed pre-treatment at baseline, after 2 weeks and after 6 weeks of treatment. Lumbar spine global stiffness (GS) were calculated from the force-displacement curves obtained using i) hand palpation, ii) a hand-held device, and iii) an automated indenter device. Lumbar FRR was assessed during trunk flexion-extension using surface electromyography. The primary outcomes were RMDQ and pain intensity measured by visual analog scale (VAS). Mixed-effects regression models were used to analyze the data. The mean age of the 82 participants was 45 years; 48% were female; and 84% reported LBP >1 year. The mean (standard deviation) baseline pain intensity and RMDQ were 46.1 (18.1) and 9.5 (4.3), respectively. The mean reduction (95% confidence interval) after 6 weeks in pain intensity and RMDQ were 20.1 mm (14.1 to 26.1) and 4.8 (3.7 to 5.8). There was a small change over time in the palpatory GS but not in the hand-held or automated GS, nor in FRR. The addition of each physiologic variable did not affect the model-estimated changes in VAS or RMDQ over time. There was no association seen between physiological variables and LBP intensity. Higher levels of hand-held GS at L3 and automated GS were significantly associated with higher levels of RMDQ (p

    Many people with low back pain (LBP) become frequent users of healthcare services in their attempt to find treatments that minimise the severity of their symptoms. Back School consists of a therapeutic programme given to groups of people that includes both education and exercise. However, the content of Back School has changed over time and appears to vary widely today. This review is an update of a Cochrane review of randomised controlled trials (RCTs) evaluating the effectiveness of Back School. We split the Cochrane review into two reviews, one focusing on acute and subacute LBP, and one on chronic LBP. The objective of this systematic review was to determine the effect of Back School on pain and disability for adults with chronic non-specific LBP; we included adverse events as a secondary outcome. In trials that solely recruited workers, we also examined the effect on work status. We searched for trials in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, two other databases and two trials registers to 15 November 2016. We also searched the reference lists of eligible papers and consulted experts in the field of LBP management to identify any potentially relevant studies we may have missed. We placed no limitations on language or date of publication. We included only RCTs and quasi-RCTs evaluating pain, disability, and/or work status as outcomes. The primary outcomes for this update were pain and disability, and the secondary outcomes were work status and adverse events. Two review authors independently performed the 'Risk of bias' assessment of the included studies using the 'Risk of bias' assessment tool recommended by The Cochrane Collaboration. We summarised the results for the short-, intermediate-, and long-term follow-ups. We evaluated the overall quality of evidence using the GRADE approach. For the outcome pain, at short-term follow-up, we found very low-quality evidence that Back School is more effective than no

    Different Grazing Incidence Diffraction (GID) methods for the analysis of thin films and multilayer structures are reviewed in three sections: the reflectivity is developed in the first one, which includes the non-specular diffuse scattering. The second one is devoted to the extremely asymmetric Bragg diffraction and the third one to the in-plane Bragg diffraction. Analytical formulations of the scattered intensities are developed for each geometry, in the framework of the kinetical analysis as well as the dynamical theory. Experimental examples are given to illustrate the quantitative possibility of the GID techniques.

    A prospective, randomized controlled trial. To examine long-term effects and costs of combined manipulative treatment, stabilizing exercises, and physician consultation compared with physician consultation alone for chronic low back pain (cLBP). An obvious gap exists in knowledge concerning long-term efficacy and cost-effectiveness of manipulative treatment methods. Of 204 patients with cLBP whose Oswestry Disability Index (ODI) was at least 16%, 102 were randomized into a combined manipulative treatment, exercise, and physician consultation group (i.e., a combination group), and 102 to a consultation alone group. All patients were clinically examined, informed about their back pain, and encouraged to stay active and exercise according to specific instructions based on clinical evaluation. Treatment included 4 sessions of manual therapy and stabilizing exercises aimed at correcting the lumbopelvic rhythm. Questionnaires inquired about pain (visual analog scale (VAS)), disability (ODI), health-related quality of life (15D Quality of Life Instrument), satisfaction with care, and costs. Significant improvement occurred in both groups on every self-rated outcome measurement. Within 2 years, the combination group showed only a slightly more significant reduction in VAS (P = 0.01, analysis of variance) but clearly higher patient satisfaction (P = 0.001, Pearson chi2) as compared to the consultation group. Incremental analysis showed that for combined group compared to consultation group, a one-point change in VAS scale cost $512. Physician consultation alone was more cost-effective for both health care use and work absenteeism, and led to equal improvement in disability and health-related quality of life. It seems obvious that encouraging information and advice are major elements for the treatment of patients with cLBP.

    Muscle samples were obtained at necropsy from 225 horses and ponies 1 year of age or older. Samples were processed in routine manner and were stained with hematoxylin and eosin and with periodic acid-Schiff for glycogen. Sections were examined for abnormal glycogen content and amylase-resistant complex polysaccharide and for chronic myopathic change (excessive fiber size variation, increase in number of internal nuclei). A total of 101 horses and ponies with lesions of polysaccharide storage myopathy were identified. Age of affected horses ranged from one to 30 years, with a mean of 14.7 years. Mean age of nonaffected horses was 12 years. Incidence of polysaccharide storage myopathy varied depending on breed; Thoroughbreds had the lowest (27%) and draft-related horses had the highest (86%) incidence. Chronic myopathic changes were more severe in polysaccharide storage myopathy-affected horses than in nonaffected horses. Results of this study indicate that polysaccharide storage myopathy is a common disorder of many breeds of horses and ponies.
