To study the role of individual and occupational risk factors for asthma in furniture workers. 296 workers were examined (258 men, 38 women) with a questionnaire of respiratory symptoms and diseases, baseline spirometry, bronchial provocative test with methacholine, and skin prick tests. Non-specific bronchial hyperreactivity was defined as when a provocative dose with a fall of 20% in forced expiratory volume in 1 second (PD20FEV1) was < 0.8 mg and atopy in the presence of at least one positive response to skin prick tests. Workers were subdivided into spray painters (exposed to low concentrations of diisocyanates and solvents), woodworkers (exposed to wood dusts), and assemblers (control group). The prevalences of attacks of shortness of breath with wheezing and dyspnoea were higher in spray painters (13.5% and 11.5% respectively) than in woodworkers (7.7% and 6.3%) or in assemblers (1.6% and 1.6%); prevalences of chronic cough, asthma, and rhinitis were also slightly but not significantly higher in spray painters and in woodworkers than in assemblers. The difference in the prevalence of respiratory symptoms among the job titles was due to the atopic subjects, who showed a higher prevalence of chronic cough, wheeze, shortness of breath with wheeze, dyspnoea, and asthma in spray painters than in the other groups. The prevalence of non-specific bronchial hyperreactivity in subjects who performed bronchial provocative tests was 17.7%, with no significant difference among groups. Asthma symptoms were significantly associated with non-specific bronchial hyperreactivity. Asthma-like symptoms plus non-specific bronchial hyperreactivity was found in 4% of assemblers, 10% of woodworkers, and 13.3% of spray painters (chi 2 = 2.6, NS). Multiple logistic analysis taking into account individual (smoke, atopy, age) and occupational (job titles) risk factors confirmed that spray painters had higher prevalence of chronic cough than assemblers, and a trend in increasing the prevalence of shortness of breath with wheeze, dyspnoea, and asthma. Painters in the furniture industry, particularly atopic subjects, are at higher risk of asthma-like symptoms than other job titles. In these workers asthma-like symptoms are more sensitive than non-specific bronchial hyperreactivity in detecting a negative effect of the occupational exposure.

2015-09-01

This study tested whether race and ethnic group differences exist for lifetime major depressive disorder and/or general anxiety disorder with one or more chronic medical conditions. Data from the National Survey of American Life, which included 3570 African American, 1438 Caribbean Black, and 891 non-Hispanic White adults were analyzed. Outcomes included at least one and multiple chronic medical conditions, from a list of 14 medical conditions (e.g., arthritis, cancer, diabetes, kidney disease, stroke, heart disease, etc.). Logistic regressions were fitted to data to determine how the association between major depressive disorder, general anxiety disorder, and one or more chronic medical conditions vary across race and ethnicity. Lifetime major depressive disorder (but not lifetime general anxiety disorder) was associated with at least one chronic medical condition among African Americans and Caribbean Blacks, but not non-Hispanic Whites. Lifetime major depressive disorder was similarly associated with multiple chronic medical conditions among African Americans, Caribbean Blacks, and non-Hispanic Whites. For Caribbean Blacks, stronger associations were found between major depressive disorder and general anxiety disorder with one or more chronic medical conditions compared to African Americans and non-Hispanic Whites. Findings suggest that race and ethnicity may shape the links between comorbid psychiatric disorders and chronic medical conditions. Mental health screening of individuals with chronic medical conditions in primary health-care settings may benefit from tailoring based on race and ethnicity. More research is needed to understand why associations between physical and mental health vary among race and ethnic groups.

The aim of this study was to identify treatment-specific predictors of the effectiveness of a method of evidence-based treatment: cognitive treatment of illness perceptions. This study focuses on what treatment works for whom, whereas most prognostic studies focusing on chronic non-specific low back pain rehabilitation aim to reduce the heterogeneity of the population of patients who are suitable for rehabilitation treatment in general. Three treatment-specific predictors were studied in patients with chronic non-specific low back pain receiving cognitive treatment of illness perceptions: a rational approach to problem-solving, discussion skills and verbal skills. Hierarchical linear regression analysis was used to assess their predictive value. Short-term changes in physical activity, measured with the Patient-Specific Functioning List, were the outcome measure for cognitive treatment of illness perceptions effect. A total of 156 patients with chronic non-specific low back pain participated in the study. Rational problem-solving was found to be a significant predictor for the change in physical activity. Discussion skills and verbal skills were non-significant. Rational problem-solving explained 3.9% of the total variance. The rational problem-solving scale results are encouraging, because chronic non-specific low back pain problems are complex by nature and can be influenced by a variety of factors. A minimum score of 44 points on the rational problem-solving scale may assist clinicians in selecting the most appropriate candidates for cognitive treatment of illness perceptions.

Current scientific evidence on the management of chronic non-specific low back pain highlights the benefits of physical exercise. This goal is frequently undermined due to lack of education of the subjects on the multifactorial, benign, and non-specific nature of low back pain, which can lead to a chronic disease with genuine psychosocial risk factors. Its influence may not only interfere with individual decision to adopt more adaptive coping behaviors, but also with the endogenous mechanisms of pain neuromodulation. Thus, the educational strategies and control of these factors have become important objectives to be incorporated into the management of the disorder and research guidelines. This paper presents the theoretical models and the scientific basis on which it has based the design of an educational tool for patients with chronic non-specific low back pain treated in Primary Care physiotherapy. Structure, content and objectives are also presented. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

Cortical lesions constitute an important part of multiple sclerosis pathology. Although inflammation appears to play a role in their formation, the mechanisms leading to demyelination and neurodegeneration are poorly understood. We aimed to identify some of these mechanisms by combining gene expression studies with neuropathological analysis. In our study, we showed that the combination of inflammation, plaque-like primary demyelination and neurodegeneration in the cortex is specific for multiple sclerosis and is not seen in other chronic inflammatory diseases mediated by CD8-positive T cells (Rasmussen’s encephalitis), B cells (B cell lymphoma) or complex chronic inflammation (tuberculous meningitis, luetic meningitis or chronic purulent meningitis). In addition, we performed genome-wide microarray analysis comparing micro-dissected active cortical multiple sclerosis lesions with those of tuberculous meningitis (inflammatory control), Alzheimer’s disease (neurodegenerative control) and with cortices of age-matched controls. More than 80% of the identified multiple sclerosis-specific genes were related to T cell-mediated inflammation, microglia activation, oxidative injury, DNA damage and repair, remyelination and regenerative processes. Finally, we confirmed by immunohistochemistry that oxidative damage in cortical multiple sclerosis lesions is associated with oligodendrocyte and neuronal injury, the latter also affecting axons and dendrites. Our study provides new insights into the complex mechanisms of neurodegeneration and regeneration in the cortex of patients with multiple sclerosis. PMID:23687122

Objective We assessed the life-time prevalence (LTP) of chronic low back pain (LBP) in young Korean males. We also evaluated the relationship between lumbar spinal lesions and their health related quality-of-life (HRQOL). Methods A cross-sectional, self-reported survey was conducted in Korean males (aged 19-year-old) who underwent physical examinations for the conscript. We examined 3331 examinees in November 2014. We included 2411 subjects, who accepted to participate this study without any comorbidities. We interviewed using simple binary questions for their LBP experience and chronicity. HRQOL was assessed by Short-Form Health-Survey-36 (SF-36) in chronic LBP and healthy control groups. Radiological assessment was performed in chronic LBP group to determine whether there were any pathological causes of their symptoms. Results The LTP of chronic LBP was 13.4%. Most (71.7%) of them didn't have any lumbar spinal lesions (i.e., non-specific chronic LBP). The SF-36 subscale and summary scores were significantly lower in subjects with chronic LBP. Between specific and non-specific chronic LBP group, all physical and mental subscale scores were significantly lower in specific chronic LBP group, except mental health (MH) subscale score. In MH subscale and mental component summary score, statistical significant differences didn't appear between two groups (p=0.154, 0.126). Conclusion In Korean males 19 years of age, the LTP of chronic LBP was 13.4%, and more than two-thirds were non-specific chronic LBP. Chronic LBP had a significant impact on HRQOL. The presence of lumbar spinal pathoanatomical lesions affected mainly on the physical aspect of HRQOL. It influenced little on the mental health. PMID:25628807

There is a relation between deficits of the proprioceptive system and movement control dysfunction in patients with chronic low back pain (LBP) but, the exact mechanism of this relation is unknown. Exercise therapy has been recognized as an effective method for low back pain treatment. In spite of this, it is not clear which of the various exercise therapy programs lead to better results. Therefore, the present analyze the efficacy of a HUBER study aims to exercise system mediated sensorimotor training protocol on proprioceptive system, lumbar movement control (LMC) and quality of life (QOL) in patients with chronic non-specific LBP. Quasi-experimental study. 53 patients with chronic non-specific LBP (mean age 37.55 ± 6.67 years,and Body Mass Index (BMI) 22.4 ± 3.33) were selected by using Roland-Morris Disability Questionnaire (RMQ) and were assigned into two experimental (N= 27) and control groups (N= 26) The experimental group underwent a five-week (10 sessions) Sensorimotor training by using the Human Body Equalizer (HUBER) spine force under the supervision of an investigator. The movement control battery tests, the HUBER machine testing option, goniometer and visual analogue scale used for movement control, neuromuscular coordination, proprioception and LBP assessment respectively. The assessments were completed in pre-test and after five weeks. The paired and sample T tests were used for data analysis in SPSS program version 18 (Significance level were set at a P value < 0.05). The HUBER system mediated sensorimotor training demonstrated significant improvement in the proprioceptive system, LMC and QOL (P= 0.001). Also There was a significant reduction in the pain scores of subjects with chronic non-specific LBP in the sensorimotor group (P= 0.001). In this study, only the short term effects of the sensorimotor training were examined. The results suggest that a sensorimotor training program causes significant improvement in patients with chronic non-specific LBP. Future research should be carried out with a larger sample size to examine the long term effects of the sensorimotor training program on treatment of patients with chronic non-specific LBP. Considering the efficacy of the sensorimotor training, it is recommended that this intervention should be applied to treatment of patients with chronic non-specific LBP in the future.

Multiple myeloma is one of the most common malignancies encountered in clinical practice. Renal involvement in myeloma is a well-recognized entity. Although rare, another special situation that a nephrologist can encounter is myeloma occurring in a patient with preexisting chronic kidney disease (CKD) due to other etiologies. Anemia, bone pains and hypercalcemia, which commonly indicate the diagnosis of myeloma in the general population, are not useful in the presence of CKD. The sensitivity and specificity of serum free light chain assay is decreased in the presence of renal failure. Chemotherapy-related adverse effects are high compared with that in patients without CKD; this is attributed to the decreased clearance of drugs and the additive effect of chemotherapy-related adverse effects to the complications of CKD. Autologous and allogenic bone marrow transplantation can be attempted in this group of patients with non-myeloablative-conditioning regimens. Combined bone marrow and renal transplantation remains a viable option in this group of patients to increase life expectancy and quality of life.

Few studies comprehensively evaluate which types of life stress are most strongly associated with depressive episode onsets, over and above other forms of stress, and comparisons between acute and chronic stress are particularly lacking. Past research implicates major (moderate to severe) stressful life events (SLEs), and to a lesser extent, interpersonal forms of stress; research conflicts on whether dependent or independent SLEs are more potent, but theory favors dependent SLEs. The present study used five years of annual diagnostic and life stress interviews of chronic stress and SLEs from two separate samples (Sample 1 N = 432; Sample 2 N = 146) transitioning into emerging adulthood; one sample also collected early adversity interviews. Multivariate analyses simultaneously examined multiple forms of life stress to test hypotheses that all major SLEs, then particularly interpersonal forms of stress, and then dependent SLEs would contribute unique variance to major depressive episode (MDE) onsets. Person-month survival analysis consistently implicated chronic interpersonal stress and major interpersonal SLEs as statistically unique predictors of risk for MDE onset. In addition, follow-up analyses demonstrated temporal precedence for chronic stress; tested differences by gender; showed that recent chronic stress mediates the relationship between adolescent adversity and later MDE onsets; and revealed interactions of several forms of stress with socioeconomic status (SES). Specifically, as SES declined, there was an increasing role for non-interpersonal chronic stress and non-interpersonal major SLEs, coupled with a decreasing role for interpersonal chronic stress. Implications for future etiological research were discussed. PMID:26301973

An Empirical Study of Chronic Diseases in the United States: A Visual Analytics Approach to Public Health

2018-01-01

In this research we explore the current state of chronic diseases in the United States, using data from the Centers for Disease Control and Prevention and applying visualization and descriptive analytics techniques. Five main categories of variables are studied, namely chronic disease conditions, behavioral health, mental health, demographics, and overarching conditions. These are analyzed in the context of regions and states within the U.S. to discover possible correlations between variables in several categories. There are widespread variations in the prevalence of diverse chronic diseases, the number of hospitalizations for specific diseases, and the diagnosis and mortality rates for different states. Identifying such correlations is fundamental to developing insights that will help in the creation of targeted management, mitigation, and preventive policies, ultimately minimizing the risks and costs of chronic diseases. As the population ages and individuals suffer from multiple conditions, or comorbidity, it is imperative that the various stakeholders, including the government, non-governmental organizations (NGOs), policy makers, health providers, and society as a whole, address these adverse effects in a timely and efficient manner.

2016-04-20

Non-specific chronic low back pain is an occupational hazard for nurses. It may result in persistent and disabling pain for some people. There are many techniques for investigating, assessing and treating chronic low back pain. However, research to support some of these interventions and the assumptions that underlie them is limited. Interventions that may be beneficial are not always available to those who need them. Changes to service provision are required to rectify this situation and provide effective treatment for patients with non-specific chronic low back pain.

People with multiple chronic conditions often struggle with managing their health. The purpose of this research was to identify specific challenges of patients with multiple chronic conditions and to use the findings to form design principles for a telemonitoring system tailored for these patients. Semi-structured interviews with 15 patients with multiple chronic conditions and 10 clinicians were conducted to gain an understanding of their needs and preferences for a smartphone-based telemonitoring system. The interviews were analyzed using a conventional content analysis technique, resulting in six themes. Design principles developed from the themes included that the system must be modular to accommodate various combinations of conditions, reinforce a routine, consolidate record keeping, as well as provide actionable feedback to the patients. Designing an application for multiple chronic conditions is complex due to variability in patient conditions, and therefore, design principles developed in this study can help with future innovations aimed to help manage this population.

Though numerous polymorphisms have been associated with risk of developing lymphoma, how these variants function to promote tumorigenesis is poorly understood. Here, we report that lymphoma risk SNPs, especially in the non-Hodgkin’s lymphoma subtype chronic lymphocytic leukemia, are significantly enriched for co-localization with epigenetic marks of active gene regulation. These enrichments were seen in a lymphoid-specific manner for numerous ENCODE datasets, including DNase-hypersensitivity as well as multiple segmentation-defined enhancer regions. Furthermore, we identify putatively functional SNPs that are both in regulatory elements in lymphocytes and are associated with gene expression changes in blood. We developed an algorithm, UES, that uses a Monte Carlo simulation approach to calculate the enrichment of previously identified risk SNPs in various functional elements. This multiscale approach integrating multiple datasets helps disentangle the underlying biology of lymphoma, and more broadly, is generally applicable to GWAS results from other diseases as well.

Pseudomonads typically carry multiple non-identical alleles of the post-transcriptional regulator rsmA. In Pseudomonas aeruginosa, RsmN is notable in that its structural rearrangement confers distinct and overlapping functions with RsmA. However, little is known about the specificities of RsmN for its target RNAs and overall impact on the biology of this pathogen. We purified and mapped 503 transcripts directly bound by RsmN in P. aeruginosa. About 200 of the mRNAs identified encode proteins of demonstrated function including some determining acute and chronic virulence traits. For example, RsmN reduces biofilm development both directly and indirectly via multiple pathways, involving control of Pel exopolysaccharide biosynthesis and c-di-GMP levels. The RsmN targets identified are also shared with RsmA, although deletion of rsmN generally results in less pronounced phenotypes than those observed for ΔrsmA or ΔrsmArsmNind mutants, probably as a consequence of different binding affinities. Targets newly identified for the Rsm system include the small non-coding RNA CrcZ involved in carbon catabolite repression, for which differential binding of RsmN and RsmA to specific CrcZ regions is demonstrated. The results presented here provide new insights into the intricacy of riboregulatory networks involving multiple but distinct RsmA homologues.

OBJECTIVES: To study the role of individual and occupational risk factors for asthma in furniture workers. METHODS: 296 workers were examined (258 men, 38 women) with a questionnaire of respiratory symptoms and diseases, baseline spirometry, bronchial provocative test with methacholine, and skin prick tests. Non-specific bronchial hyperreactivity was defined as when a provocative dose with a fall of 20% in forced expiratory volume in 1 second (PD20FEV1) was < 0.8 mg and atopy in the presence of at least one positive response to skin prick tests. Workers were subdivided into spray painters (exposed to low concentrations of diisocyanates and solvents), woodworkers (exposed to wood dusts), and assemblers (control group). RESULTS: The prevalences of attacks of shortness of breath with wheezing and dyspnoea were higher in spray painters (13.5% and 11.5% respectively) than in woodworkers (7.7% and 6.3%) or in assemblers (1.6% and 1.6%); prevalences of chronic cough, asthma, and rhinitis were also slightly but not significantly higher in spray painters and in woodworkers than in assemblers. The difference in the prevalence of respiratory symptoms among the job titles was due to the atopic subjects, who showed a higher prevalence of chronic cough, wheeze, shortness of breath with wheeze, dyspnoea, and asthma in spray painters than in the other groups. The prevalence of non-specific bronchial hyperreactivity in subjects who performed bronchial provocative tests was 17.7%, with no significant difference among groups. Asthma symptoms were significantly associated with non-specific bronchial hyperreactivity. Asthma-like symptoms plus non-specific bronchial hyperreactivity was found in 4% of assemblers, 10% of woodworkers, and 13.3% of spray painters (chi 2 = 2.6, NS). Multiple logistic analysis taking into account individual (smoke, atopy, age) and occupational (job titles) risk factors confirmed that spray painters had higher prevalence of chronic cough than assemblers, and a trend in increasing the prevalence of shortness of breath with wheeze, dyspnoea, and asthma. CONCLUSIONS: Painters in the furniture industry, particularly atopic subjects, are at higher risk of asthma-like symptoms than other job titles. In these workers asthma-like symptoms are more sensitive than non-specific bronchial hyperreactivity in detecting a negative effect of the occupational exposure.   PMID:9924457

Considerations on long-term immuno-intervention in the treatment of multiple sclerosis: an expert opinion.

2016-10-01

As management of multiple sclerosis (MS) requires life-long treatment with disease-modifying agents, any risks associated with long-term use should be considered when evaluating therapeutic options. Immune cells of the innate and adaptive immune systems play various roles in the pathogenesis of MS. MS therapies affect the immune system, each with a unique mode of action, and consequently possess different long-term safety profiles. Rare, but serious safety concerns, including an increased risk of infection and cancer, have been associated with immunosuppressant use. The risks associated with newer immunosuppressive agents, which target specific elements of MS disease pathophysiology, are not yet fully established as the duration of clinical trials is relatively short and post-marketing experience is limited. Non-immunosuppressants used to treat MS have well-defined safety profiles established over a large number of patient-years demonstrating them to be well-tolerated long-term treatment options. When considering the long-term use of disease-modifying agents for treating MS, classification as immunosuppressants or non-immunosuppressants can be useful when evaluating potential risks associated with chronic use. A successful therapeutic strategy for any serious, chronic disease such as MS should weigh effectiveness versus long-term safety of available treatments.

Abstract Objective To explore the perspectives of patients who live with multiple chronic conditions as they relate to the challenges of self-management. Data sources On September 30, 2013, we searched MEDLINE, EMBASE, and CINAHL using relevant key words including chronic disease, comorbidity, multimorbidity, multiple chronic conditions, self-care, self-management, perspective, and perception. Study selection Three reviewers assessed and extracted the data from the included studies after study quality was rated. Qualitative thematic synthesis method was then used to identify common themes. Twenty-three articles met the inclusion criteria, with most coming from the United States. Synthesis Important themes raised by people living with multiple chronic conditions related to their ability to self-manage included living with undesirable physical and emotional symptoms, with pain and depression highlighted. Issues with conflicting knowledge, access to care, and communication with health care providers were raised. The use of cognitive strategies, including reframing, prioritizing, and changing beliefs, was reported to improve people’s ability to self-manage their multiple chronic conditions. Conclusion This study provides a unique view into patients’ perspectives of living with multiple chronic conditions, which are clearly linked to common functional challenges as opposed to specific diseases. Future policy and programming in self-management support should be better aligned with patients’ perspectives on living with multiple chronic conditions. This might be achieved by ensuring a more patient-centred approach is adopted by providers and health service organizations. PMID:25642490

Addressing Chronic Malnutrition through Multi-Sectoral, Sustainable Approaches: A Review of the Causes and Consequences

PubMed Central

Reinhardt, Kristina; Fanzo, Jessica

2014-01-01

Chronic malnutrition, including stunting, is an important example of a global challenge that spans multiple sectors, specifically health, agriculture, and the environment. The objective of this paper is to review current knowledge on the causes and consequences of chronic malnutrition and their relationship with multiple sectors. Understanding the causes includes approaching chronic malnutrition from the basic, underlying, and immediate levels. The causes reach from macro-level environmental influences to specific micronutrient intake. In order to effectively address stunting, it is important to understand the timing of stunting and the ability of individuals to catch up in terms of linear growth, cognitive ability, and immune function. The consequences of chronic malnutrition are transgenerational and they have an impact at the individual, community, and national level in the short- and long-term. There are still many gaps in knowledge regarding both the causes and consequences of chronic malnutrition, particularly when it comes to the interaction with agriculture and the environment, and understanding these gaps is important to addressing the burden of chronic malnutrition through evidence-based interventions.

There is growing interest in preventable, non-smoking causes of chronic obstructive pulmonary disease (COPD), among which are chronic exposures to respiratory irritants in the workplace. Reviews of occupational COPD in specific occupations and industries and in general populations; supplemented with other or more recently published material. There is good evidence for an increased risk of COPD from certain specific exposures (coal mine dust, silica, welding fume, textile dust, agricultural dust, cadmium fume). Less clear is the causal role of non-specific dusts or fumes/gases in general populations where the available literature is notably uncritical. Other specific exposures, such as diesel fume; interactions between specific exposures and cigarette smoking; the development of safe working limits. Occupations with large numbers of exposed employees, particularly in low-income countries.

Responses to early-life adversity may differ by sex. We investigated the sex-specific impact of early-life adversity on chronic pain, chronic multisite pain, and somatizing tendency with chronic pain. We examined 4229 respondents aged 20-79 years who participated in the Pain Associated Cross-Sectional Epidemiological Survey in Japan. Outcomes were: 1) chronic pain prevalence, 2) multisite pain (≥3 sites) prevalence, and 3) multiple somatic symptoms (≥3 symptoms) among respondents with chronic pain related to the presence or absence of early-life adversity. Multivariable-adjusted odds ratios (ORs) were calculated with 95% confidence intervals using a logistic regression model including age, smoking status, exercise routine, sleep time, body mass index, household expenditure, and the full distribution of scores on the Mental Health Inventory-5. We further adjusted for pain intensity when we analyzed the data for respondents with chronic pain. The prevalence of chronic pain was higher among respondents reporting the presence of early-life adversity compared with those reporting its absence, with multivariable ORs of 1.62 (1.22-2.15, p <0.01) in men and 1.47 (1.13-1.90, p <0.01) in women. Among women with chronic pain, early-life adversity was associated with multisite pain and multiple somatic symptoms; multivariable ORs were 1.78 (1.22-2.60, p <0.01) for multisite pain and 1.89 (1.27-2.83, p <0.01) for ≥3 somatic symptoms. No associations were observed between early-life adversity and chronic multisite pain or multiple somatic symptoms among men with chronic pain. Early-life adversity may be linked to a higher prevalence of chronic pain among both sexes and to multisite pain and somatizing tendency among women with chronic pain.

[Purpose] The aim of this study was to compare the effects of "McGill stabilization exercises" and "conventional physiotherapy" on pain, functional disability and active back flexion and extension range of motion in patients with chronic non-specific low back pain. [Subjects and Methods] Thirty four patients with chronic non-specific low back pain were randomly assigned to McGill stabilization exercises group (n=17) and conventional physiotherapy group (n=17). In both groups, patients performed the corresponding exercises for six weeks. The visual analog scale (VAS), Quebec Low Back Pain Disability Scale Questionnaire and inclinometer were used to measure pain, functional disability, and active back flexion and extension range of motion, respectively. [Results] Statistically significant improvements were observed in pain, functional disability, and active back extension range of motion in McGill stabilization exercises group. However, active back flexion range of motion was the only clinical symptom that statistically increased in patients who performed conventional physiotherapy. There was no significant difference between the clinical characteristics while compared these two groups of patients. [Conclusion] The results of this study indicated that McGill stabilization exercises and conventional physiotherapy provided approximately similar improvement in pain, functional disability, and active back range of motion in patients with chronic non-specific low back pain. However, it appears that McGill stabilization exercises provide an additional benefit to patients with chronic non-specific low back, especially in pain and functional disability improvement.

The aim of this study was to investigate the possible alterations in postural control during upright standing in subjects with non-specific chronic low back pain and the effect of Kinesio taping on the postural control. Twenty subjects with non-specific chronic low back pain and twenty healthy subjects participated in this study. The center of pressure excursion was evaluated before the intervention for both groups, and immediately after intervention for the low back pain group. Independent sample t-test, Mann-Whitney test and repeated measure ANOVA were used for the statistical analysis of the data. There were significant differences in the center of pressure excursion between the low back pain group versus the healthy group. The results of the ANOVA demonstrated a statistically significant difference in the mean COP displacement and velocity before Kinesio Taping, immediately after, and 24 h after in the low back pain group. There are poor postural control mechanisms in subjects with non-specific chronic low back pain. Kinesio taping seems to change postural control immediately and have lasting effects until the day after. Copyright © 2017 Elsevier Ltd. All rights reserved.

Sacroiliac joint (SIJ) disorders are common in patients with chronic lower back pain. Minimally invasive surgical options have been shown to be effective for the treatment of chronic SIJ dysfunction. To determine the cost-effectiveness of minimally invasive SIJ fusion. Data from two prospective, multicenter, clinical trials were used to inform a Markov process cost-utility model to evaluate cumulative 5-year health quality and costs after minimally invasive SIJ fusion using triangular titanium implants or non-surgical treatment. The analysis was performed from a third-party perspective. The model specifically incorporated variation in resource utilization observed in the randomized trial. Multiple one-way and probabilistic sensitivity analyses were performed. SIJ fusion was associated with a gain of approximately 0.74 quality-adjusted life years (QALYs) at a cost of US$13,313 per QALY gained. In multiple one-way sensitivity analyses all scenarios resulted in an incremental cost-effectiveness ratio (ICER) <$26,000/QALY. Probabilistic analyses showed a high degree of certainty that the maximum ICER for SIJ fusion was less than commonly selected thresholds for acceptability (mean ICER =$13,687, 95% confidence interval $5,162-$28,085). SIJ fusion provided potential cost savings per QALY gained compared to non-surgical treatment after a treatment horizon of greater than 13 years. Compared to traditional non-surgical treatments, SIJ fusion is a cost-effective, and, in the long term, cost-saving strategy for the treatment of SIJ dysfunction due to degenerative sacroiliitis or SIJ disruption.

Chronic illnesses care represents a challenging issue for people well-being and future health systems' sustainability. Promotion of self-care is considered a key point for chronically ill patients' care. The aim of this literature was to explore: how self-care of chronic illness has been theoretically defined; how self-care can be assessed in clinical and research settings; what associations exist between self-care and health outcomes of chronically ill patients. A wide range of definitions and terminologies related to self-care of chronic illness has been found in the literature. Although some common elements useful to explain the concept of self-care have been identified, the physical, cognitive, emotional and social processes underlying self-care remain controversial and poorly defined. Valid and reliable disease-specific assessment tools have been developed and used in a growing number of studies; however, the lack of utilization of standardized instruments in clinical practice has been referred by many authors. Significant correlations between self-care of chronic illness and outcome measures e.g. general health status, quality of life and healthcare costs, are reported by a limited number of studies. Supporting patient self-care is recognized as a crucial factor in chronic illness care. A deeper analysis of variables and processes influencing self-care could help for a full description of the phenomenon. A systematic evaluation of self-care in health professionals' everyday clinical practice is strongly recommended. The development of general non-disease-specific assessment tools could facilitate the evaluation of complex patients, especially those with multiple co-morbidities. Although self-care has been recognized as a vital intermediate outcome, further large-scale studies clarifying the association between self-care and patients' and health systems' outcomes are needed.

Nursing personnel have high risk for incidence of low back pain (LBP) followed by development of chronic pain and disability. Multiple risk factors such as patient handling, night shift work and lack of supporting work culture have been identified. In subacute LBP, high-fear avoidance is prognostic for more pain, disability and not returning to work. Lack of leisure-time physical activity predicts long-term sickness absence. The purpose of this study is to compare effectiveness of 6-month neuromuscular exercise and counselling in treating back pain in female nursing personnel with recurrent non-specific LBP pain compared with either (exercise or counselling) alone and a non-treatment control group. The design is of a double-blinded four-arm randomised controlled trial with cost-effectiveness evaluation at 12 and 24 months. The study is conducted in 3 consecutive substudies. The main eligibility criteria are experience of LBP during the past 4 weeks with intensity of at least 2 (Numeric Rating Scale 0-10) and engagement in patient handling. Sample size was estimated for the primary outcome of pain intensity (visual analogue scale). Study measurements are outlined according to the model of International Classification of Functioning, Disability and Health, which incorporates the biopsychosocial processes assessed. This study is carried out conforming to the guidelines of good scientific practice and provisions of the declaration of Helsinki. Increasing physical and mental capacity with interventions taking place immediately after working hours near the worksite may reduce development of chronic LBP and work disability in female nursing personnel with recurrent non-specific LBP.

The purpose of this systematic review was to assess the effects of spinal manipulative therapy (SMT), acupuncture and herbal medicine for chronic non-specific LBP. A comprehensive search was conducted by an experienced librarian from the Cochrane Back Review Group (CBRG) in multiple databases up to December 22, 2008. Randomised controlled trials (RCTs) of adults with chronic non-specific LBP, which evaluated at least one clinically relevant, patient-centred outcome measure were included. Two authors working independently from one another assessed the risk of bias using the criteria recommended by the CBRG and extracted the data. The data were pooled when clinically homogeneous and statistically possible or were otherwise qualitatively described. GRADE was used to determine the quality of the evidence. In total, 35 RCTs (8 SMT, 20 acupuncture, 7 herbal medicine), which examined 8,298 patients, fulfilled the inclusion criteria. Approximately half of these (2 SMT, 8 acupuncture, 7 herbal medicine) were thought to have a low risk of bias. In general, the pooled effects for the studied interventions demonstrated short-term relief or improvement only. The lack of studies with a low-risk of bias, especially in regard to SMT precludes any strong conclusions; however, the principal findings, which are based upon low- to very-low-quality evidence, suggest that SMT does not provide a more clinically beneficial effect compared with sham, passive modalities or any other intervention for treatment of chronic low-back pain. There is evidence, however, that acupuncture provides a short-term clinically relevant effect when compared with a waiting list control or when acupuncture is added to another intervention. Although there are some good results for individual herbal medicines in short-term individual trials, the lack of homogeneity across studies did not allow for a pooled estimate of the effect. In general, these results are in agreement with other recent systematic reviews on SMT, but in contrast with others. These results are also in agreement with recent reviews on acupuncture and herbal medicine. Randomized trials with a low risk of bias and adequate sample sizes are directly needed.

In Yugoslavia the diseases of the respiratory system (without tuberculosis) ranges with 23% in front of all other organ-localised diseases. 53--95% of all chronic non-specific lung diseases are registrated in the chest clinics of the different republics. 67% of all lung diseases registrated belong to the obstructive syndrom, 6% are bronchial carcinomas and 27% represent the group of other chronic pulmonary diseases. 31,5% of all patients with chronic obstructive bronchitis are younger than 50 years old, 34,7% are in the age-group between 50-65 years. Assuming the best registered incidence and prevalence rates of bronchial carcinoma, chronic bronchitis, asthma and emphysema in Slowenia as a basis, the expected morbidity of these diseases in each autonomic republic are compared.

Multiple sclerosis (MS) is one of the most common neurological disorders in young adults. It is characterised by a chronic progressive course with far reaching implications on the patient's private and professional life. Based on the current literature, employment status is analysed in relation to disease-specific, therapeutic, psychosocial, and socioeconomic factors. A special emphasis is placed on the vocational status of MS patients in Germany. According national and international studies, around 40 % of all MS patients are currently unemployed. Main reasons for early retirement are disease-specific factors such as impaired mobility, disability in the upper extremities, fatigue, and cognitive impairment. According to the German Multiple Sclerosis Registry (GMSR), these symptoms are still insufficiently treated. In patients with minor motoric impairment (EDSS ≤ 3.0), depressive symptoms seem to have a major impact on employment status. Disease progression, older age at diagnosis, and hard physical work are negative predictors in terms of employment situation. The lack of flexible working hours, the inability to have flexible resting times at work, a lack of understanding from colleagues and employers as well as the personal attitude were main non-disease-specific reasons for early retirement. The current knowledge on the vocational status in MS is mainly based on international studies (e. g., Scandinavia, England, USA, Australia, MSIF Survey). For Germany, only the GMSR supports significant information on the employment status of MS patients. According to the GMSR, ataxia, fatigue and cognitive dysfunction are still insufficiently treated - a situation that is at least partly due to insufficient treatment options. Comprehensive studies that focus on a broad range of possible influencing factors on vocational status of German MS patients are currently lacking. © Georg Thieme Verlag KG Stuttgart · New York.

Stigma of visible and invisible chronic conditions.

Nurses deliver care to people with various forms of chronic illnesses and conditions. Some chronic conditions, such as paraplegia, are visible while others, such as diabetes, are invisible. Still others, such as multiple sclerosis, are both visible and invisible. Having a chronic illness or condition and being different from the general population subjects a person to possible stigmatization by those who do not have the illness. Coping with stigma involves a variety of strategies including the decision about whether to disclose the condition and suffer further stigma, or attempt to conceal the condition or aspects of the condition and pass for normal. We present a beginning framework that describes the relationship between the elements of stigma and the decision to disclose or hide a chronic condition based on its visibility or invisibility. The specific aims were to combine the results from a meta-study on qualitative research with a review of the quantitative literature, then develop a theoretical framework. Although an understanding of how patients cope with stigmatizing conditions is essential for nurses who aim to deliver comprehensive individualized patient care, there is little current literature on this subject. The relationship between visibility and invisibility and disclosure and non-disclosure remains poorly understood. A framework to facilitate a deeper understanding of the dynamics of chronic illnesses and conditions may prove useful for practice.

Autoimmune diseases (AD) are conditions in which there is the development of antibodies against self cells/ organs. AD could either be organ-specific or non-organ specific (systemic) in clinical presentation. Commonly reported ADs includes: Myasthenia gravis, Hashimoto thyroiditis, Guillian-Barre syndrome, vitiligo, type 1 diabetes mellitus, Graves diseases, Goodpastures syndrome, pemphigus, rheumatoid arthritis, systemic lupus erythematosis, Addisons disease, multiple sclerosis, pernicious anaemia, autoimmune haemolytic anaemia, chronic active hepatitis, idiopathic thrombocytopenic purpura. There is paucity of locally documented information on the occurrence of AD in same patient in our environment. We therefore report the case of a 66 year old woman who presented at the University College Hospital (UCH), Ibadan, with a spectrum of the AD, Vitiligo, rheumatoid arthritis, myasthenia gravis, impaired glucose tolerance.

The Geriatric Depression Scale (GDS) is widely used for screening and assessment of major depressive disorder (MDD). Screening scales are often culture-specific and should be evaluated for item response bias (synonymously differential item functioning, DIF) before use in clinical practice and research in a different population. In this study, we examined DIF associated with age, gender, ethnicity and chronic illness in a heterogeneous Asian population in Singapore. The GDS-15 and Structured Clinical Interview for DSM-IV diagnosis of MDD were independently administered by interviewers on 4253 non-institutionalized community living elderly subjects aged 60 years and above who were users of social service agencies. Multiple Indicator Multiple Cause latent variable modelling was used to identify DIF. We found evidence of significant DIF associated with age, gender, ethnicity and chronic illness for 8 items: dropped many activities and interests, afraid something bad is going to happen, prefer staying home to going out, more problems with memory than most, think it is (not) wonderful to be alive, feel pretty worthless, feel (not) full of energy, feel that situation is hopeless. The smaller number of minority Indian and Malay subjects and the self-report of chronic medical illnesses. In a heterogeneous mix of respondents in Singapore, eight items of the GDS-15 showed DIF for age, gender, ethnicity and chronic illness. The awareness and identification of DIF in the GDS-15 provides a rational basis for its use in diverse population groups and guiding the derivation of abbreviated scales.

Cutaneous involvement in case of lupus erythematosus (LE) is very frequent and can present both specific or non-specific manifestations. LE specific lesions can be classified in acute, subacute and chronic cutaneous LE lesions. All of them can be localized and generalized. The LE non specific lesions are not exclusive to LE disease but are often seen in patients with active systemic LE. All the cutaneous lesions are often induced or aggravated by ultraviolet light, in fact they are usually localized in sun-exposed areas. Acute cutaneous LE is associated with systemic disease, subacute cutaneous LE has been considered a subset of its own since 1979 when it was first described, chronic cutaneous LE is the most common subtype of LE. Although less frequently also the chronic cutaneous lesions can be an aspect of systemic LE (25%).

The consequences of chronic cannabis smoking in vulnerable adolescents.

Iede, Montaha Al; Nunn, Kenneth; Milne, Bronwyn; Fitzgerald, Dominic A

2017-09-01

Cannabis, like the mythic shape-shifter, presents in various guises, morphing with the perspective and context of the observer. Arguments about cannabis are confused by a myriad of debates-medical, social, ethical and political-as if a single conceptual umbrella can capture the variety and granularity of marijuana-related issues. This paper responds to marijuana use as it is commonly practised by youth in Australia. It has little to say about synthetic cannabinoids, specific medicinal cannabinoids, or medicinal properties of marijuana. We address those adolescents genetically and environmentally vulnerable to mental illness, with specific emphasis on indigenous and neurodevelopmentally impaired young people who show patterns of usage and response very different to adults and more resilient members of the population. Specifically, the practice of mixing tobacco with marijuana by aboriginal youth, and the resultant coalition of dependencies, will likely presage a rise in pulmonary and central nervous system pathology over the coming decades. Aboriginal youth begin using earlier, persist longer, and take greater quantities of cannabis than non-indigenous youth. This paper recommends practical interventions to reduce the multiple health consequences of chronic cannabis use in young people, especially indigenous young people. Copyright © 2016.

Non-invasive, photonics-based diagnostic, imaging, monitoring, and light delivery techniques for the recognition, quantification and treatment of malignant and chronic inflammatory conditions

We report firsthand on innovative developments in non-invasive, biophotonic techniques for a wide range of diagnostic, imaging and treatment options, including the recognition and quantification of cancerous, pre-cancerous cells and chronic inflammatory conditions. These techniques have benefited from the ability to target the affected site by both monochromatic light and broad multiple wavelength spectra. The employment of such wavelength or color-specific properties embraces the fluorescence stimulation of various photosensitizing drugs, and the instigation and detection of identified fluorescence signatures attendant upon laser induced fluorescence (LIF) phenomena as transmitted and propagated by precancerous, cancerous and normal tissue. In terms of tumor imaging and therapeutic and treatment options, we have exploited the abilities of various wavelengths to penetrate to different depths, through different types of tissues, and have explored quantifiable absorption and reflection characteristics upon which diagnostic assumptions can be reliably based and formulated. These biophotonic-based diagnostic, sensing and imaging techniques have also benefited from, and have been further enhanced by, the integrated ability to provide various power levels to be employed at various stages in the procedure. Applications are myriad, including non-invasive, non destructive diagnosis of in vivo cell characteristics and functions; light-based tissue analysis; real-time monitoring and mapping of brain function and of tumor growth; real time monitoring of the surgical completeness of tumor removal during laser-imaged/guided brain resection; diagnostic procedures based on fluorescence life-time monitoring, the monitoring of chronic inflammatory conditions (including rheumatoid arthritis), and continuous blood glucose monitoring in the control of diabetes.

Remodeling Functional Connectivity in Multiple Sclerosis: A Challenging Therapeutic Approach.

Neurons in the central nervous system are organized in functional units interconnected to form complex networks. Acute and chronic brain damage disrupts brain connectivity producing neurological signs and/or symptoms. In several neurological diseases, particularly in Multiple Sclerosis (MS), structural imaging studies cannot always demonstrate a clear association between lesion site and clinical disability, originating the "clinico-radiological paradox." The discrepancy between structural damage and disability can be explained by a complex network perspective. Both brain networks architecture and synaptic plasticity may play important roles in modulating brain networks efficiency after brain damage. In particular, long-term potentiation (LTP) may occur in surviving neurons to compensate network disconnection. In MS, inflammatory cytokines dramatically interfere with synaptic transmission and plasticity. Importantly, in addition to acute and chronic structural damage, inflammation could contribute to reduce brain networks efficiency in MS leading to worse clinical recovery after a relapse and worse disease progression. These evidence suggest that removing inflammation should represent the main therapeutic target in MS; moreover, as synaptic plasticity is particularly altered by inflammation, specific strategies aimed at promoting LTP mechanisms could be effective for enhancing clinical recovery. Modulation of plasticity with different non-invasive brain stimulation (NIBS) techniques has been used to promote recovery of MS symptoms. Better knowledge of features inducing brain disconnection in MS is crucial to design specific strategies to promote recovery and use NIBS with an increasingly tailored approach.

There has been little research on the economic status of those with multiple health conditions, particularly on the relationship between multiple health conditions and wealth. This paper will assess the difference in the value and type of wealth assets held by Australians who have multiple chronic health conditions. Using Health&WealthMOD, a microsimulation model of the 45-64-year-old Australian population in 2009, a counterfactual analysis was undertaken. The actual proportion of people with different numbers of chronic health conditions with any wealth, and the value of this wealth was estimated. This was compared with the counterfactual values had the individuals had no chronic health conditions. There was no change in the proportion of people with one health condition who actually had any wealth, compared to the counterfactual proportion had they had no chronic health conditions. Ninety-four percent of those with four or more health conditions had some accumulated wealth; however, under the counterfactual, 100% would have had some accumulated wealth. There was little change in the value of non-income-producing assets under the counterfactual, regardless of number of health conditions. Those with four or more chronic health conditions had a mean value of $17 000 in income-producing assets; under the counterfactual, the average would have been $78 000. This study has highlighted the variation in the value of wealth according to number of chronic health conditions, and hence the importance of considering multiple morbidities when discussing the relationship between health and wealth. © The Author 2014.

Chronic pain in vulnerable elderly people is still poorly recognized and treated, both at home and in hospitals and care and nursing homes. Vulnerable elderly people experience and express pain differently to relatively healthy adults, especially when they suffer from cognitive impairment or specific conditions. Determining the nature and severity of the pain requires the use of pain assessment instruments that have been validated for use in vulnerable elderly people. Effective treatment of pain demands careful diagnosis and pharmacological and non-pharmacological interventions that have proven effectiveness in vulnerable elderly people. The combination of multiple morbidity and poly-pharmacy increases the chance of side-effects and complications. In addition, the pharmacokinetic and pharmacodynamic characteristics of many drugs are different in vulnerable elderly people. The advice is to start with a lower dose of pain medication and gradually build up a level on the basis of pain relief and side-effects ('start low, go slow!').

Foods do certainly play an important role in human health. This cross sectional study investigated the effect of lifestyle food on chronic diseases. In specific, it compared these diseases between vegetarians and non- vegetarians in Jordan in 2012. Questionnaires were distributed and the responses of 97 vegetarians and 97 non-vegetarians were analyzed. Chi-square and Wilcoxon signed ranks tests showed statistically significant differences between the two groups. In particular, chronic diseases including Diabetes, Hypertension, and Obesity were more prevalence among non-vegetarians compared to vegetarian respondents. PMID:23283037

HIV-associated mortality has been significantly reduced with antiretroviral therapy (ART), and HIV infection has become a chronic disease that frequently coexists with many disorders, including substance abuse (Azar et al. 2010; Phillips et al. 2001). Alcohol and drugs of abuse may modify host-pathogen interactions at various levels including behavioral, metabolic, and immune consequences of HIV infection, as well as the ability of the virus to integrate into the genome and replicate in host cells. Identifying mechanisms responsible for these interactions is complicated by many factors, such as the tissue specific responses to viral infection, multiple cellular mechanisms involved in inflammatory responses, neuroendocrine and localized responses to infection, and kinetics of viral replication. An integrated physiological analysis of the biomedical consequences of chronic alcohol and drug use or abuse on disease progression is possible using rhesus macaques infected with simian immunodeficiency virus (SIV), a relevant model of HIV infection. This review will provide an overview of the data gathered using this model to show that chronic administration of two of the most commonly abused substances, alcohol and cannabinoids (Δ9-Tetrahydrocannabinol; THC), affect host-pathogen interactions.

Objective There is little high-quality evidence on the efficacy of the Pilates-based exercises for the treatment of chronic nonspecific low back pain. Therefore, the objective of this paper is to present a study protocol to investigate the efficacy of adding Pilates-based exercises to a minimum intervention in patients with chronic non-specific low back pain. Methods This randomized controlled trial will recruit 86 patients of both sexes, aged between 18 and 60 years, with chronic non-specific low back pain. The participants will be randomly allocated into 2 treatment groups: the Booklet Group, which will receive a booklet with postural orientations, and the Pilates Group, which will receive the same booklet in addition to a Pilates-based exercises program. The general and specific functional capacities of the patient, kinesiophobia, pain intensity, and the global perceived effect will be evaluated by a blinded assessor before randomization and at 6 weeks and 6 months after randomization. In addition, the expectations of the participants and their confidence in the treatment will be evaluated before the randomization and after the first treatment session, respectively. Conclusions It is hoped that the results of this study will provide high-quality evidence on the usefulness of Pilates-based exercises in the treatment of chronic non-specific low back pain.

Trichuris (whipworm) infects 1 billion people worldwide, and causes a disease (trichuriasis) that results in major socioeconomic losses in both humans and pigs. Trichuriasis relates to an inflammation of the large intestine manifested in bloody diarrhoea, and chronic disease can cause malnourishment and stunting in children. Paradoxically, Trichuris of pigs has shown substantial promise as a treatment for human autoimmune disorders, including inflammatory bowel disease (IBD) and multiple sclerosis (MS). Here, we report ~80 megabase (Mb) draft assemblies of the genomes of adult male and female T. suis, and explore stage-, sex- and tissue-specific transcription of messenger and small non-coding RNAs.

Developmental cortical malformations comprise a large spectrum of histopathological brain abnormalities and syndromes. Their genetic, developmental and clinical complexity suggests they should be better understood in terms of the complementary action of independently timed perturbations (i.e., the multiple-hit hypothesis). However, understanding the underlying biological processes remains puzzling. Here we induced developmental cortical malformations in offspring, after intraventricular injection of methylazoxymethanol (MAM) in utero in mice. We combined extensive histological and electrophysiological studies to characterize the model. We found that MAM injections at E14 and E15 induced a range of cortical and hippocampal malformations resembling histological alterations of specific genetic mutations and transplacental mitotoxic agent injections. However, in contrast to most of these models, intraventricularly MAM-injected mice remained asymptomatic and showed no clear epilepsy-related phenotype as tested in long-term chronic recordings and with pharmacological manipulations. Instead, they exhibited a non-specific reduction of hippocampal-related brain oscillations (mostly in CA1); including theta, gamma and HFOs; and enhanced thalamocortical spindle activity during non-REM sleep. These data suggest that developmental cortical malformations do not necessarily correlate with epileptiform activity. We propose that the intraventricular in utero MAM approach exhibiting a range of rhythmopathies is a suitable model for multiple-hit studies of associated neurological disorders. PMID:24782720

Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. AUTOIMMNUNE THYROID DISEASE AND OTHER ORGAN SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. AUTOIMMUNE THYROID DISEASE AND OTHER ORGAN NON-SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sjögren, systemic sclerosis and mixed connective tissue disease. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Otherwise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

The objective of this study was to analyse the relationships between the major chronic diseases and multiple morbidity, with mortality, incident disability in basic activities of daily living, and loss of mobility in the elderly. A total of 943 participants were selected from the FRADEA Study, using available baseline data of chronic diseases, and at the follow-up visit of mortality, incident disability, and loss of mobility. The analysis was made of the unadjusted and adjusted association between the number of chronic diseases, the number of 14 pre-selected diseases, and the presence of two or more chronic diseases (multiple morbidity) with adverse health events recorded. Participants with a higher number of diseases (OR 1.11; 95% CI: 1.02-1.22), and 14 pre-selected diseases (OR 1.19; 95% CI: 1.03-1.38) had a higher adjusted mortality risk, but not a higher incident disease or mobility loss risk. Subjects with multiple morbidity had a higher non-significant mortality risk (HR 1.45; 95% CI: 0.87-2.43), than those without multiple morbidity. Disability-free mean time in participants with and without multiple morbidity was 846±34 and 731±17 days, respectively (Log-rank χ(2) 7.45. P=.006), and with our without mobility loss was 818±32 and 696±13 days, respectively (Log rank χ(2) 10.99. P=.001). Multiple morbidity was not associated with mortality, incident disability in ADL, or mobility loss in adults older than 70 years, although if mortality is taken into account, the number of chronic diseases is linear.

Defining the neurotoxin derived illness chronic ciguatera using markers of chronic systemic inflammatory disturbances: a case/control study.

PubMed

Shoemaker, Ritchie C; House, Dennis; Ryan, James C

2010-01-01

Ciguatoxins are extremely potent neurotoxins, produced by tropical marine dinoflagellates, that persistently enter into our food web. Over 100,000 people annually experience acute ciguatera poisoning from consuming toxic fish. Roughly 5% of these victims will develop chronic ciguatera (CC), a widespread, multisymptom, multisystem, chronic illness that can last tens of years. CC is marked by disproportionate disability and non-specific refractory symptoms such as fatigue, cognitive deficits and pain, and is suggestive of other illnesses. Its unknown pathophysiology makes both diagnosis and treatment difficult. We wanted to compare objective parameters of visual contrast sensitivity testing, measures of innate immune response and genetic markers in cases to controls to assess the potential for the presence of persistent inflammatory parameters that are demonstrated in other biotoxin associated illnesses at a single specialty clinic. Using 59 CC cases and 59 controls we present in retrospective review, in all cases, abnormalities in immune responses paralleling the chronic systemic inflammatory response syndrome seen in several other chronic diseases. This study defines a preliminary case definition using medical history, total symptoms, visual contrast sensitivity, HLA DR genotype analysis, reduction of regulatory neuropeptides VIP and MSH, and multiple measures of inflammatory immune response, especially C4a and TGFβ1, thereby providing a basis for identification and targeted therapy. CC provides a model for chronic human illness associated with initiation of inflammatory responses by biologically produced neurotoxins. Copyright © 2010 Elsevier Inc. All rights reserved.

Although nearly 112 million residents of the United States belong to a non-white ethnic group, the literature about differences in health indicators across ethnic groups is limited almost exclusively to Hispanics. Features of the social experience of many ethnic groups including immigration, discrimination, and acculturation may plausibly influence mortality risk. We explored life expectancy and age-adjusted mortality risk of Arab-Americans (AAs), relative to non-Arab and non-Hispanic Whites in Michigan, the state with the largest per capita population of AAs in the US. Data were collected about all deaths to AAs and non-Arab and non-Hispanic Whites in Michigan between 1990 and 2007, and year 2000 census data were collected for population denominators. We calculated life expectancy, age-adjusted all-cause, cause-specific, and age-specific mortality rates stratified by ethnicity and gender among AAs and non-Arab and non-Hispanic Whites. Among AAs, life expectancies among men and women were 2.0 and 1.4 years lower than among non-Arab and non-Hispanic White men and women, respectively. AA men had higher mortality than non-Arab and non-Hispanic White men due to infectious diseases, chronic diseases, and homicide. AA women had higher mortality than non-Arab and non-Hispanic White women due to chronic diseases. Despite better education and higher income, AAs have higher age-adjusted mortality risk than non-Arab and non-Hispanic Whites, particularly due to chronic diseases. Features specific to AA culture may explain some of these findings. © 2011 El-Sayed et al.

To investigate the effects of a Pilates exercise program on disability, pain, lumbar mobility, flexibility and balance in patients with chronic non-specific low back pain. Randomized controlled trial. University laboratory. A total of 54 patients with chronic non-specific low back pain. Patients were randomly allocated to an experimental group ( n=27) included in a Pilates exercise program or to a control group ( n=27) receiving information in a form of a leaflet. Disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), current, average and pain at it least and at its worst (Visual Analogue Scales), lumbar mobility (modified Shober test), flexibility (finger-to-floor test) and balance (single limb stance test) were measured at baseline and after the intervention. A between-group analysis showed significant differences in the intervention group compared to the control group for both disability scores, the Rolland-Morris questionnaire (mean change±standard deviation of 5.31±3.37 and 2.40±6.78 respectively and between-groups mean difference of 3.2 ± 4.12, p=0.003) and the Oswestry Disability Index ( p<0.001), current pain ( p=0.002) and pain at it least ( p=0.033), flexibility (0.032) and balance (0.043). An 8-week Pilates exercise program is effective in improving disability, pain, flexibility and balance in patients with chronic non-specific low back pain.

To evaluate the effectiveness of isometric exercises as compared to general exercises in chronic non-specific neck pain. For this randomised controlled trial total 68 patients (34 each group) with chronic non-specific neck pain were recruited from Alain Poly Clinic and Institute of Physical Medicine & Rehabilitation Dow University of Health Sciences, Karachi between May, 2012 and August, 2012. Simple randomisation method was used to assign participants into isometric exercise group and general exercise groups. The isometric exercise group performed exercises for neck muscle groups with a rubber band and general exercises group performed active range of movement exercises for all neck movements. Patients in both groups received 3 supervised treatment sessions per week for 12 weeks. Visual Analogue Scale (VAS), North wick Park Neck Pain Questionnaire and goniometer were used to assess pain, disability and neck range of movements at baseline and after 12 weeks. Both interventions showed statistically significant improvements in pain, function and range of movement p = 0.001f or isometric exercise group, p = 0.04 for general exercises group and p = 0.001 for range of movement. However, mean improvements in post intervention VAS score and North wick Park Neck Pain Questionnaire score was better in isometric exercises group as compared to general exercise group. In conclusion, both interventions are effective in the treatment of chronic non-specific neck pain however; isometric exercises are clinically more effective than general exercises.

Hepatic steatosis occurs in 40-70% of patients chronically infected with hepatitis C virus [chronic hepatitis C (CH-C)]. Hepatic steatosis in CH-C is associated with progressive liver disease and a low response rate to antiviral therapy. Gene expression profiles were examined in CH-C patients with and without hepatic steatosis, non-alcoholic steatohepatitis (NASH) and fibrosis. This study included 65 CH-C patients who were not receiving antiviral treatment. Total RNA was extracted from peripheral blood mononuclear cells, quantified and used for one-step reverse transcriptase-polymerase chain reaction to profile 153 mRNAs that were normalized with six 'housekeeping' genes and a reference RNA. Multiple regression and stepwise selection assessed differences in gene expression and the models' performances were evaluated. Models predicting the grade of hepatic steatosis in patients with CH-C genotype 3 involved two genes: SOCS1 and IFITM1, which progressively changed their expression level with the increasing grade of steatosis. On the other hand, models predicting hepatic steatosis in non-genotype 3 patients highlighted MIP-1 cytokine encoding genes: CCL3 and CCL4 as well as IFNAR and PRKRIR. Expression levels of PRKRIR and SMAD3 differentiated patients with and without superimposed NASH only in the non-genotype 3 cohort (area under the receiver operating characteristic curve=0.822, P-value 0.006]. Gene expression signatures related to hepatic fibrosis were not genotype specific. Gene expression might predict moderate to severe hepatic steatosis, NASH and fibrosis in patients with CH-C, providing potential insights into the pathogenesis of hepatic steatosis and fibrosis in these patients.

Allende-Salazar, Rubén F; Rada, Gabriel

2017-06-14

The use of cannabinoids has been proposed as an analgesic for different painful conditions, especially for chronic pain refractory to usual treatment. However, its real efficacy and safety remains controversial. We sought to determine whether cannabinoids are an effective treatment for chronic non-cancer pain. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified 37 systematic reviews including 41 studies overall, of which 32 were randomized trials relevant for the question of interest. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded it is not clear whether cannabinoids decrease pain in patients with chronic non-cancer pain because the certainty of available evidence is very low. On the other hand, they are associated with significant adverse effects.

Overgenerality and delay of the retrieval of autobiographical memory (AM) are well documented in a range of clinical conditions, particularly in patients with emotional disorder. The present study extended the investigation to chronic pain, attempting to identify whether the retrieval of AM in patients with chronic pain tends to be overgeneral or delayed. With an observational cross-sectional design, we evaluated the AM both in patients with chronic pain and healthy controls by Autobiographical Memory Test. Pain conditions were assessed using the pain diagnostic protocol, the short-form McGill Pain Questionnaire (SF-MPQ), and the Pain Self-Efficacy Questionnaire (PSEQ). Emotion was assessed using the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory. Subjects included 176 outpatients with chronic pain lasting for at least 6 months and 170 healthy controls. 1) Compared with the healthy group, the chronic pain group had more overgeneral memories (OGMs) (F = 29.061, P < 0.01) and longer latency (F = 13.602, P < 0.01). 2) In the chronic pain group, the stepwise multiple regression models for variables predicting OGM were significant (P < 0.01). Specifically, the variance in OGM scores could be predicted by the BDI score (9.7%), pain chronicity (4.3%), PSEQ score (7.1%), and Affective Index (of SF-MPQ) score (2.7%). 3) In the chronic pain group, the stepwise multiple regression models for variables predicting latency were significant (P < 0.05). Specifically, the variance in latency could be predicted by age (3.1%), pain chronicity (2.7%), pain duration (4.3%), and PSEQ score (2.0%). The retrieval of AM in patients with chronic pain tends to be overgeneral and delayed, and the retrieval style of AM may be contributed to negative emotions and chronic pain conditions.

As early as the 1990s, chronic critical illness, a distinct syndrome of persistent high-acuity illness requiring management in the ICU, was reported under a variety of descriptive terms including the "neuropathy of critical illness," "myopathy of critical illness," "ICU-acquired weakness," and most recently "post-intensive care unit syndrome." The widespread implementation of targeted shock resuscitation, improved organ support modalities, and evidence-based protocolized ICU care has resulted in significantly decreased in-hospital mortality within surgical ICUs, specifically by reducing early multiple organ failure deaths. However, a new phenotype of multiple organ failure has now emerged with persistent but manageable organ dysfunction, high resource utilization, and discharge to prolonged care facilities. This new multiple organ failure phenotype is now clinically associated with the rapidly increasing incidence of chronic critical illness in critically ill surgery patients. Although the underlying pathophysiology driving chronic critical illness remains incompletely described, the persistent inflammation, immunosuppression, and catabolism syndrome has been proposed as a mechanistic framework in which to explain the increased incidence of chronic critical illness in surgical ICUs. The purpose of this review is to provide a historic perspective of the epidemiologic evolution of multiple organ failure into persistent inflammation, immunosuppression, and catabolism syndrome; describe the mechanism that drives and sustains chronic critical illness, and review the long-term outcomes of surgical patients who develop chronic critical illness.

Patients with chronic low back pain exhibit characteristics such as clinical pain, psychological symptoms and neuromuscular adaptations. The purpose of this study was to determine the independent contribution of clinical pain, psychological factors and neuromuscular adaptations to disability in patients with chronic low back pain. Clinical pain intensity, pain catastrophizing, fear-avoidance beliefs, anxiety, neuromuscular adaptations to chronic pain and neuromuscular responses to experimental pain were assessed in 52 patients with chronic low back pain. Lumbar muscle electromyographic activity was assessed during a flexion-extension task (flexion relaxation phenomenon) to assess both chronic neuromuscular adaptations and neuromuscular responses to experimental pain during the task. Multiple regressions showed that independent predictors of disability included neuromuscular adaptations to chronic pain (β=0.25, p=0.006, sr(2)=0.06), neuromuscular responses to experimental pain (β=-0.24, p=0.011, sr(2)=0.05), clinical pain intensity (β=0.28, p=0.002, sr(2)=0.08) and psychological factors (β=0.58, p<0.001, sr(2)=0.32). Together, these predictors accounted for 65% of variance in disability (R(2)=0.65 p<0.001). The current investigation revealed that neuromuscular adaptations are independent from clinical pain intensity and psychological factors, and contribute to inter-individual differences in patients' disability. This suggests that disability, in chronic low back pain patients, is determined by a combination of factors, including clinical pain, psychological factors and neuromuscular adaptations.

In chronic lymphocytic leukemia, usually a monoclonal disease, multiple productive immunoglobulin heavy chain gene rearrangements are identified sporadically. Prognostication of such cases based on immunoglobulin heavy variable gene mutational status can be problematic, especially if the different rearrangements have discordant mutational status. To gain insight into the possible biological mechanisms underlying the origin of the multiple rearrangements, we performed a comprehensive immunogenetic and immunophenotypic characterization of 31 cases with the multiple rearrangements identified in a cohort of 1147 patients with chronic lymphocytic leukemia. For the majority of cases (25/31), we provide evidence of the co-existence of at least two B lymphocyte clones with a chronic lymphocytic leukemia phenotype. We also identified clonal drifts in serial samples, likely driven by selection forces. More specifically, higher immunoglobulin variable gene identity to germline and longer complementarity determining region 3 were preferred in persistent or newly appearing clones, a phenomenon more pronounced in patients with stereotyped B-cell receptors. Finally, we report that other factors, such as TP53 gene defects and therapy administration, influence clonal selection. Our findings are relevant to clonal evolution in the context of antigen stimulation and transition of monoclonal B-cell lymphocytosis to chronic lymphocytic leukemia. PMID:24038023

The appendix inflammatory process is the most common cause of chronic abdominal pain in the right lower quadrant. The frequency of appendiceal lumen obstruction by fecalith ranges from 10 to 20%; few cases of obstruction by multiple fecaliths had been reported. Sixty-nine years old male, diabetic and hypertensive in control, he underwent bowel resection 30 years previously. He completed 6 months with intermittent, mild pain in the right lower quadrant abdomen; 14 days prior to admission with increasing pain, nausea, vomiting, constipation, abdominal distension and absence of peristalsis; 12,750 leukocytes, neutrophils 90%; plain abdominal radiography without specific bowel pattern, TAC with 3 dense images in right lower quadrant; exploratory laparotomy was performed and perforated appendix with 3 free fecaliths was found. Histopathological report showed fibrosis and lymphocytic infiltrate in the muscle layer of the cecal appendix consistent with chronic appendicitis. The most common obstruction of the appendix lumen is by a single fecalith. In this case the patient had chronic appendicitis secondary to appendiceal lumen obstruction by multiple fecaliths. Reviewing the international literature any case of chronic appendicitis associated with the presence of multiple fecaliths was found. Copyright © 2016 Academia Mexicana de Cirugía A.C.

Cannabinoids affect immune responses in ways that may be beneficial for autoimmune diseases. We sought to determine whether chronic Cannabis use differentially modulates a select number of immune parameters in healthy controls and individuals with multiple sclerosis (MS cases). Subjects were enrolled and consented to a single blood draw, matched for age and BMI. We measured monocyte migration isolated from each subject, as well as plasma levels of endocannabinoids and cytokines. Cases met definition of MS by international diagnostic criteria. Monocyte cell migration measured in control subjects and individuals with MS was similarly inhibited by a set ratio of phytocannabinoids. The plasma levels of CCL2 and IL17 were reduced in non-naïve cannabis users irrespective of the cohorts. We detected a significant increase in the endocannabinoid arachidonoylethanolamine (AEA) in serum from individuals with MS compared to control subjects, and no significant difference in levels of other endocannabinoids and signaling lipids irrespective of Cannabis use. Chronic Cannabis use may affect the immune response to similar extent in individuals with MS and control subjects through the ability of phytocannabinoids to reduce both monocyte migration and cytokine levels in serum. From a panel of signaling lipids, only the levels of AEA are increased in individuals with MS, irrespective of Cannabis use or not. Our results suggest that both MS cases and controls respond similarly to chronic Cannabis use with respect to the immune parameters measured in this study.

Effectiveness of mat Pilates or equipment-based Pilates in patients with chronic non-specific low back pain: a protocol of a randomised controlled trial

PubMed Central

2013-01-01

Background Chronic low back pain is an expensive and difficult condition to treat. One of the interventions widely used by physiotherapists in the treatment of chronic non-specific low back pain is exercise therapy based upon the Pilates principles. Pilates exercises can be performed with or without specific equipment. These two types of Pilates exercises have never been compared on a high-quality randomised controlled trial. Methods/design This randomised controlled trial with a blinded assessor will evaluate eighty six patients of both genders with chronic low back pain, aged between 18 and 60 years, from one Brazilian private physiotherapy clinic. The patients will be randomly allocated into two groups: Mat Group will perform the exercises on the ground while the Equipment-based Group will perform the Pilates method exercises on the following equipment: Cadillac, Reformer, Ladder Barrel, and Step Chair. The general and specific disability of the patient, kinesiophobia, pain intensity and global perceived effect will be evaluated by a blinded assessor before randomisation and at six weeks and six months after randomisation. In addition, the expectation of the participants and their confidence with the treatment will be evaluated before randomisation and after the first treatment session, respectively. Discussion This will be the first study aiming to compare the effectiveness of Mat and Equipment-based Pilates exercises in patients with chronic non-specific low back pain. The results may help health-care professionals in clinical decision-making and could potentially reduce the treatment costs of this condition.

The aim of the study is to evaluate the clinical and X-ray results of the Upper Cervical Chiropractic care through the specific adjustments (corrections) of C1-C2 on patients with chronic venous cerebral-spinal insufficiency (CCSVI) and multiple sclerosis (MS). We studied a sample of 77 patients before and after the Upper Cervical Chiropractic care, and we analyzed: A) The change of the X-ray parameters; B) The clinical results using a new set of questions. The protocol of the C1- C2 upper Cervical Chiropractic treatment, specific for these patients, lasts four months. From a haemodynamic point of view we divided the patients in 3 types: Type 1 - purely vascular with intravenous alterations; Type 2 - "mechanical" with of external venous compressions; Type 3 - mixed. We found an improvement in all kinds of subluxations after the treatment with respect to the pre-treatment X-ray evaluation, with a significant statistical difference. The differences between the clinical symptoms before and after the specific treatment of C1-C2 are statistically significant with p<0.001 according to the CHI-Square test revised by Yates. The preliminary X-ray and clinical improvements of the Upper Cervical Chiropractic corrections on C1- C2 on these patients with CCSVI and MS encourage us to continue with our studies. We believe that the Upper Cervical correction on C1-C2 could be the main non-invasive treatment of the CCSVI mechanical type in patients with MS. Further studies are required to evaluate the correlation between the Upper Cervical Chiropractic correction on C1-C2 on the cerebral venous drainage and the cerebro-spinal fluid.

There is a growing burden of chronic non-communicable disease (CNCD). Managing CNCDs requires use of multiple sources of health and social care data, and information about coordination and outcomes. Many people with CNCDs have multimorbidity. Problems with data quality exacerbate challenges in measuring quality and health outcomes especially where there is multimorbidity. We have developed an ontological toolkit to support research and quality improvement studies in CNCDs using heterogeneous data, with diabetes mellitus as an exemplar. International experts held a workshop meeting, with follow up discussions and consensus building exercise. We generated conceptual statements about problems with a CNCD that ontologies might support, and a generic reference model. There were varying degrees of consensus. We propose a set of tools, and a four step method: (1) Identification and specification of data sources; (2) Conceptualisation of semantic meaning; (3) How available routine data can be used as a measure of the process or outcome of care; (4) Formalisation and validation of the final ontology.

The prevalence of chronic non-cancer pain has not been specifically reported in Chile. In order to assess its prevalence and impact, we designed a tool based on previously published survey studies. We analyzed a sample of 784 subjects to determine the prevalence of chronic non-cancer pain, with a maximum variability of 50%, a confidence interval (CI) of 95%, and an estimation error of 3.5%. Finally, a cross-sectional cell phone survey was conducted on a nationally representative probability sample of 865 subjects of over 18 years, in November 2013. The prevalence of chronic non-cancer pain was estimated by using expansion factors according to national projections by age group and gender, from the Chilean National Institute of Statistics for the year 2010. The estimated prevalence of chronic non-cancer pain was 32.1% (95% CI: 26.5-36.0). The respondents with chronic non-cancer pain presented the following results: 65.7% had moderate pain, and 20.8%, severe pain; 65.6% had somatic pain, 31.7% neuropathic pain, and 2.7% visceral pain. Approximately 70% reported they were receiving some kind of pharmacological treatment with certain frequency. In 64.9%, medication was prescribed by a physician. The prevalence of sick leave in workers was 30.22%, with a median duration of 14 days (interquartile range: 14; range: 1-60). Chronic non-oncological pain occurs in 32% of Chilean adults. These figures provide the first measurement of chronic non-cancer pain in the Chilean population. Chronic non-oncological pain impact as a public health problem is revealed, given the high prevalence found, and the elevated private and social costs involved.

Although Internet-based cognitive behavior therapy (iCBT) is an effective treatment for chronic tinnitus, several patients do not improve. In the current study, baseline and process variables were compared between non-responders and responders. Data from patients participating in two randomized controlled trials on iCBT for chronic tinnitus were re-analyzed. Based on the literature, a pre-post difference on the "Tinnitus Handicap Inventory" (THI) of less than seven points improvement was used to operationalize non-response. Associations between non-response and baseline variables (age, gender, and questionnaire scores), patient progress (THI), the process of the therapeutic alliance ("Working Alliance Inventory-Short Revised"; WAI-SR), as well as other process variables (number of logins, amount of messages sent from therapists to patients) were investigated. The results showed that non-responders had a less favorable change on the THI than responders already at mid-treatment (p < .05). The alliance (WAI-SR) during iCBT was not associated with non-response. Non-responders showed more severe sleep disturbances, logged in less in the iCBT platform, and received fewer messages from the therapists than responders, but these differences were mostly not significant anymore when correcting for multiple testing. To conclude, no symptom change in the first half of iCBT for chronic tinnitus patients is a risk factor of not benefiting from iCBT.

Rurality and ethnicity in adolescent physical illness: are children of the growing rural Latino population at excess health risk?

This study's objectives are to: investigate potential additive and multiplicative influences of rurality and race/ethnicity on chronic physical illness in a nationally representative sample of youth; and examine intra-Latino processes using a Latino sub-sample. Specifically, we examine how rurality and individual psychosocial processes reflected by acculturation proxies (generational status and use of the English language at home) link to chronic physical illness of Latino youth. Finally, we examine whether these associations and the levels of chronic illness differ across Latino subgroups. Logistic-normal (binomial) modeling analyses examine multilevel influences on physical health using longitudinal data from a nationally representative sample (N = 13,905) of white, African American, Latino, Asian, and Native American adolescents between the ages of 12 and 19 participating in the National Longitudinal Study of Adolescent Health. Prevalence rates of certain chronic illnesses (obesity, asthma, and high cholesterol) among Latino adolescents exceed rates for the same illnesses among white adolescents. Comparisons between rural and non-rural youth reveal a rurality disadvantage in terms of any chronic illness likelihood among Latino, Asian, and Native American youth not evident among whites or African Americans. Among Latino youth (N = 2,505), Mexican Americans show lower health risk for any chronic illness compared to other Latino groups. However, third generation Latinos and those who primarily speak English at home experience higher risk for any chronic illness than do those of first or second generation status, with amplification of the risk linked to English use at home among Latino youth living in rural areas.

Detection of multiple biologically relevant molecules was accomplished at sub-ng/mL levels in highly fouling media using fiber- optic based surface plasmon resonance sensors. Myocardial infarction markers, myoglobin and cTnI, were quantified in full serum with limits of detection below 1 ng/mL. Biologically relevant levels are between 15-30 ng/mL and 1-5 ng/mL for myoglobin and cTnI respectively. Cytokines involved in chronic wound healing, Interleukin 1, Interleukin 6, and tumor necrosis factor α, were detected at around 1 ng/mL in cell culture media. Preliminary results in monitoring these cytokines in cell cultures expressing the cytokines were obtained. The protein diagnostic of spinal muscular atrophy, survival motor neuron protein, was quantified from cell lysate. To obtain such results in complex media, the sensor's stability to non-specific protein adsorption had to be optimized. A layer of the N-hydroxysuccinimide ester of 16-mercaptohexadecanoic acid is attached to the sensor. This layer optimizes the antibody attachment to the sensor while minimizing the non-specific signal from serum proteins.

Aboriginal populations in northern Canada are experiencing rapid changes in their environments, which may negatively impact on health status. The purpose of our study was to compare chronic conditions and risk factors in northern Aboriginal populations, including First Nations (FN), Inuit and Métis populations, and northern non-Aboriginal populations. Data were from the Canadian Community Health Survey for the period from 2005 to 2008. Weighted multiple logistic regression models tested the association between ethnic groups and health outcomes. Model covariates were age, sex, territory of residence, education and income. Odds ratios (ORs) are reported and a bootstrap method calculated 95% confidence intervals (CIs) and p values. Odds of having at least one chronic condition was significantly lower for the Inuit (OR = 0.59; 95% CI: 0.43-0.81) than for non-Aboriginal population, but similar among FN, Métis and non-Aboriginal populations. Prevalence of many risk factors was significantly different for Inuit, FN and Métis populations. Aboriginal populations in Canada's north have heterogeneous health status. Continued chronic disease and risk factor surveillance will be important to monitor changes over time and to evaluate the impact of public health interventions.

In order to better understand the emergence of chronic non-communicable diseases in low- and middle-income countries this article seeks to present, in context, different transitional processes which societies and populations are currently undergoing. Relevant factors for specific contexts such as Peru are described, including internal migration, urbanization and profiles of adversity in early life, all of them linked to chronic non-communicable diseases, including obesity and overweight. The capacity-load model, which considers chronic disease risk in adulthood as a function of two generic traits, metabolic capacity and metabolic load, is described. The contribution of rural-to-urban migration to this problem is also presented. Finally, these topics are framed within pending challenges for public health in Peru.

A marked increase in leukemia risks was the first and most striking late effect of radiation exposure seen among the Hiroshima and Nagasaki atomic bomb survivors. This paper presents analyses of radiation effects on leukemia, lymphoma, and multiple myeloma incidence in the Life Span Study cohort of atomic bomb survivors updated 14 years since the last comprehensive report on these malignancies. These analyses make use of tumor- and leukemia-registry-based incidence data on 113,011 cohort members with 3.6 million person-years of follow-up from late 1950 through the end of 2001. In addition to a detailed analysis of the excess risk for all leukemias other than chronic lymphocytic leukemia or adult T-cell leukemia (neither of which appear to be radiation-related), we present results for the major hematopoietic malignancy types: acute lymphoblastic leukemia, chronic lymphocytic leukemia, acute myeloid leukemia, chronic myeloid leukemia, adult T-cell leukemia, Hodgkin and non-Hodgkin lymphoma, and multiple myeloma. Poisson regression methods were used to characterize the shape of the radiation dose response relationship and, to the extent the data allowed, to investigate variation in the excess risks with sex, attained age, exposure age, and time since exposure. In contrast to the previous report that focused on describing excess absolute rates, we considered both excess absolute rate (EAR) and excess relative risk (ERR) models and found that ERR models can often provide equivalent and sometimes more parsimonious descriptions of the excess risk than EAR models. The leukemia results indicated that there was a non-linear dose response for leukemias other than chronic lymphocytic leukemia or adult T-cell leukemia, which varied markedly with time and age at exposure, with much of the evidence for this non-linearity arising from the acute myeloid leukemia risks. Although the leukemia excess risks generally declined with attained age or time since exposure, there was evidence that the radiation-associated excess leukemia risks, especially for acute myeloid leukemia, had persisted throughout the follow-up period out to – 55 years after the bombings. As in earlier analyses, there was a weak suggestion of a radiation dose response for non-Hodgkin lymphoma among men with no indication of such an effect among women. There was no evidence of radiation-associated excess risks for either Hodgkin lymphoma or multiple myeloma. PMID:23398354

Effect of thoracic mobilization on respiratory parameters in chronic non-specific low back pain: A randomized controlled trial.

PubMed

Babina, R; Mohanty, P P; Pattnaik, M

2016-02-19

Altered respiratory function has been found to be associated with back pain. Limited chest excursion in subjects with chronic low back pain (CLBP) may be due to co-contraction or bracing of erector spinae and abdominal muscles; their flexed spinal posture; and/or their compromised spinal stability resulting from dysfunctional transversus abdominis. To check for the effects of thoracic mobilization on respiratory parameters in subjects with chronic non-specific low back pain. Sixty-two subjects (excluding 11 dropouts) with CLBP of age group 30-60 were randomly allocated to two groups. Both groups received individualized treatment for low back pain (LBP) and HEP (home exercise program) regime of breathing exercises. In addition, group 1 received Maitland's Central postero-anterior vertebral pressure for thoracic spine (T1-T8). Total treatment duration was 10 sessions in 2 weeks (5 sessions/week). Results showed significant improvement in respiratory parameters viz. Forced Vital Capacity (FVC), Sustained Maximal Inspiratory Pressure (SMIP) and Chest Wall Expansion (CWE) and Oswestry Disability Index (ODI) in both groups (p< 0.05) at end of 2 weeks of intervention. However, improvement was significantly more in group 1 (p < 0.05) receiving additional thoracic mobilization. Subjects with non-specific chronic low back pain with or without radiation to lower limbs when treated with thoracic central PA mobilization, in addition to LBP specific treatment and breathing exercises, show an improvement in respiratory parameters and reduction in disability.

The role of pathogen specific cellular immune responses against the eliciting pathogen in development of post-infectious chronic fatigue syndrome (PI-CFS) is not known and such studies are difficult to perform. The aim of this study was to evaluate specific anti-Giardia cellular immunity in cases that developed CFS after Giardia infection compared to cases that recovered well. Patients reporting chronic fatigue in a questionnaire study three years after a Giardia outbreak were clinically evaluated five years after the outbreak and grouped according to Fukuda criteria for CFS and idiopathic chronic fatigue. Giardia specific immune responses were evaluated in 39 of these patients by proliferation assay, T cell activation and cytokine release analysis. 20 Giardia exposed non-fatigued individuals and 10 healthy unexposed individuals were recruited as controls. Patients were clinically classified into CFS (n = 15), idiopathic chronic fatigue (n = 5), fatigue from other causes (n = 9) and recovered from fatigue (n = 10). There were statistically significant antigen specific differences between these Giardia exposed groups and unexposed controls. However, we did not find differences between the Giardia exposed fatigue classification groups with regard to CD4 T cell activation, proliferation or cytokine levels in 6 days cultured PBMCs. Interestingly, sCD40L was increased in patients with PI-CFS and other persons with fatigue after Giardia infection compared to the non-fatigued group, and correlated well with fatigue levels at the time of sampling. Our data show antigen specific cellular immune responses in the groups previously exposed to Giardia and increased sCD40L in fatigued patients.

Direction-Specific Impairments in Cervical Range of Motion in Women with Chronic Neck Pain: Influence of Head Posture and Gravitationally Induced Torque.

2017-01-01

Cervical range of motion (ROM) is commonly assessed in clinical practice and research. In a previous study we decomposed active cervical sagittal ROM into contributions from lower and upper levels of the cervical spine and found level- and direction-specific impairments in women with chronic non-specific neck pain. The present study aimed to validate these results and investigate if the specific impairments can be explained by the neutral posture (defining zero flexion/extension) or a movement strategy to avoid large gravitationally induced torques on the cervical spine. Kinematics of the head and thorax was assessed in sitting during maximal sagittal cervical flexion/extension (high torque condition) and maximal protraction (low torque condition) in 120 women with chronic non-specific neck pain and 40 controls. We derived the lower and upper cervical angles, and the head centre of mass (HCM), from a 3-segment kinematic model. Neutral head posture was assessed using a standardized procedure. Previous findings of level- and direction-specific impairments in neck pain were confirmed. Neutral head posture was equal between groups and did not explain the direction-specific impairments. The relative magnitude of group difference in HCM migration did not differ between high and low torques conditions, lending no support for our hypothesis that impairments in sagittal ROM are due to torque avoidance behaviour. The direction- and level-specific impairments in cervical sagittal ROM can be generalised to the population of women with non-specific neck pain. Further research is necessary to clarify if torque avoidance behaviour can explain the impairments.

Improving quality of care for people with multiple chronic conditions (MCCs) requires performance measures reflecting the heterogeneity and scope of their care. Since most existing measures are disease specific, performance measures must be refined and new measures must be developed to address the complexity of care for those with MCCs. To describe development of the Performance Measurement for People with Multiple Chronic Conditions (PM-MCC) conceptual model. Framework development and a national stakeholder panel. We used reviews of existing conceptual frameworks of performance measurement, review of the literature on MCCs, input from experts in the multistakeholder Steering Committee, and public comment. The resulting model centers on the patient and family goals and preferences for care in the context of multiple care sites and providers, the type of care they are receiving, and the national priority domains for healthcare quality measurement. This model organizes measures into a comprehensive framework and identifies areas where measures are lacking. In this context, performance measures can be prioritized and implemented at different levels, in the context of patients' overall healthcare needs.

Insights on persistent airway infection by non-typeable Haemophilus influenzae in chronic obstructive pulmonary disease

2017-01-01

Abstract Non-typeable Haemophilus influenzae (NTHi) is the most common bacterial cause of infection of the lower airways in adults with chronic obstructive pulmonary disease (COPD). Infection of the COPD airways causes acute exacerbations, resulting in substantial morbidity and mortality. NTHi has evolved multiple mechanisms to establish infection in the hostile environment of the COPD airways, allowing the pathogen to persist in the airways for months to years. Persistent infection of the COPD airways contributes to chronic airway inflammation that increases symptoms and accelerates the progressive loss of pulmonary function, which is a hallmark of the disease. Persistence mechanisms of NTHi include the expression of multiple redundant adhesins that mediate binding to host cellular and extracellular matrix components. NTHi evades host immune recognition and clearance by invading host epithelial cells, forming biofilms, altering gene expression and displaying surface antigenic variation. NTHi also binds host serum factors that confer serum resistance. Here we discuss the burden of COPD and the role of NTHi infections in the course of the disease. We provide an overview of NTHi mechanisms of persistence that allow the pathogen to establish a niche in the hostile COPD airways. PMID:28449098

Tinnitus-related distress appears to be more strongly associated with multiple psychological factors than with any perceptual properties of tinnitus. Prior studies have not investigated the role of worry in tinnitus sufferers. Worry is a dispositional cognitive trait that involves a pervasive, non-specific, future-oriented proneness to fretting, which can foster negative affective states and catastrophic thinking about a specific trouble when the trouble is actual and present. We examined the relationship between worry and self-perceived anxiety and depressive symptoms and handicap in 54 outpatients with chronic tinnitus and sensorineural hearing loss who had been previously recruited for a randomized double-blind study on the efficacy of transmeatal low-level laser therapy for tinnitus. We measured the current anxiety and depressive symptoms with the State-Trait Anxiety Inventory Form Y-1/Self-evaluation Depression Scale, the handicap with the Tinnitus Handicap Inventory, and the proneness to worry with the Penn State Worry Questionnaire. For the psychoacoustic tinnitus measures, we considered the loudness match and the minimum masking level. We found that tinnitus-related anxiety and depressive symptoms and handicap were significantly associated with proneness to worry (linear regression models, p < 0.01), whereas no associations were found with the psychoacoustic measures. This suggests the usefulness of worry assessment when managing chronic tinnitus in clinical practice. Early therapeutic interventions for reducing proneness to worry may facilitate better adaptation to tinnitus.

A variety and rate of non-cancer diseases occurred in humans as a result of chronic exposure to ionizing radiation or to electromagnetic radiation (EMR) of high and superhigh frequency have been compared. The intensity of EMR was slightly higher than a sanitary standard for population. A risk of health impairments in workers having occupational exposure to EMR was assessed on the basis of Selie's concept of development of non-specific reaction of the body to chronic stress factors (general adaptation syndrome), models of changes in the body compensatory reserves and calculations of radiation risk after severe and chronic exposure to ionizing radiation.

Comparative efficacy of the Cognitive Behavioral Analysis System of Psychotherapy versus Supportive Psychotherapy for early onset chronic depression: design and rationale of a multisite randomized controlled trial

PubMed Central

2011-01-01

Background Effective treatment strategies for chronic depression are urgently needed since it is not only a common and particularly disabling disorder, but is also considered treatment resistant by most clinicians. There are only a few studies on chronic depression indicating that traditional psycho- and pharmacological interventions are not as effective as in acute, episodic depression. Current medications are no more effective than those introduced 50 years ago whereas the only psychotherapy developed specifically for the subgroup of chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), faired well in one large trial. However, CBASP has never been directly compared to a non-specific control treatment. Methods/Design The present article describes the study protocol of a multisite parallel-group randomized controlled trial in Germany. The purpose of the study is to estimate the efficacy of CBASP compared to supportive psychotherapy in 268 non-medicated early-onset chronically depressed outpatients. The intervention includes 20 weeks of acute treatment with 24 individual sessions followed by 28 weeks of continuation treatment with another 8 sessions. Depressive symptoms are evaluated 20 weeks after randomisation by means of the 24-item Hamilton Rating Scale of Depression (HRSD). Secondary endpoints are depressive symptoms after 12 and 48 weeks, and remission after 12, 20, and 48 weeks. Primary outcome will be analysed using analysis of covariance (ANCOVA) controlled for pre-treatment scores and site. Analyses of continuous secondary variables will be performed using linear mixed models. For remission rates, chi-squared tests and logistic regression will be applied. Discussion The study evaluates the comparative effects of a disorder-specific psychotherapy and a well designed non-specific psychological approach in the acute and continuation treatment phase in a large sample of early-onset chronically depressed patients.

Common brain mechanisms are thought to play a significant role across a multitude of chronic pain syndromes. In addition, there is strong evidence for the existence of sex differences in the prevalence of chronic pain and in the neurobiology of pain. Thus, it is important to consider sex when developing general principals of pain neurobiology. The goal of the current review is to evaluate what is known about sex-specific brain alterations across multiple chronic pain populations. A total of 15 sex difference and 143 single-sex manuscripts were identified out of 412 chronic pain neuroimaging manuscripts. Results from sex difference studies indicate more prominent primary sensorimotor structural and functional alterations in female chronic pain patients compared to male chronic pain patients; differences in the nature and degree of insula alterations, with greater insula reactivity in male patients; differences in the degree of anterior cingulate structural alterations; and differences in emotional-arousal reactivity. Qualitative comparisons of male-specific and female-specific studies appear to be consistent with the results from sex difference studies. Given these differences, mixed-sex studies of chronic pain risk creating biased data or missing important information and single-sex studies have limited generalizability. The advent of large scale neuroimaging databases will likely aid in building a more comprehensive understanding of sex differences and commonalities in brain mechanisms underlying chronic pain.

According to literature, virtual reality was found to reduce pain and kinesiophobia in patients with chronic pain. The purpose of the study was to investigate short-term effect of the virtual reality on pain, function, and kinesiophobia in patients with subacute and chronic non-specific low-back pain METHODS: This randomised controlled study in which 44 patients were randomly assigned to the traditional physiotherapy (control group, 22 subjects) or virtual walking integrated physiotherapy (experimental group, 22 subjects). Before and after treatment, Visual Analog Scale (VAS), TAMPA Kinesiophobia Scale (TKS), Oswestry Disability Index (ODI), Nottingham Health Profile (NHP), Timed-up and go Test (TUG), 6-Minute Walk Test (6MWT), and Single-Leg Balance Test were assessed. The interaction effect between group and time was assessed by using repeated-measures analysis of covariance. After treatment, both groups showed improvement in all parameters. However, VAS, TKS, TUG, and 6MWT scores showed significant differences in favor of the experimental group. Virtual walking integrated physiotherapy reduces pain and kinesiophobia, and improved function in patients with subacute and chronic non-specific low-back pain in short term.

Background: Humans have been involved with the phenomena of pain and pain relief from the ancient times. Back pain is the most common pain. In fact, eight out of ten people experience it in their lifetime. However, individuals with specific jobs, including nurses, are faced with this problem more. Nursing is in the top ten careers suffering from the most severe musculoskeletal injuries. There are non-pharmacologic and pharmacologic treatments to relieve back pain. One of the non-medical treatments of pain is called reflexology which is a branch of complementary and alternative therapies. This research has been conducted to investigate the effect of reflexology on chronic low back pain intensity. Materials and Methods: This study was a double-blind clinical trial. The study population consisted of 50 female and male nurses suffering from chronic low back pain working in hospitals affiliated with Isfahan University of Medical Sciences. The participants were divided into two groups of reflexology and non-specific massage. A questionnaire was completed through interviews and a 40 minute sessions of interventions were performed three times a week for two weeks. Pain intensity was measured by Numerical Analogue Scale for pain before and after the intervention. Descriptive and inferential statistics, including independent t-test and chi-square test, were used to analyze the data. Findings: The results showed a significantly higher reduction in pain intensity scores in the reflexology group after the intervention as compared with the non-specific massage group. However, the non-specific massage was also significantly effective in reducing pain. Conclusions: Reflexology can be effective in reducing the severity of chronic back pain, i.e. it is able to reduce pain from moderate to mild. Thus, this technique is recommended to be performed by nurses as a complementary therapy in patient care. PMID:23833620

Right Ventricular Dysfunction in Chronic Lung Disease

PubMed Central

Kolb, Todd M.; Hassoun, Paul M.

2012-01-01

Right ventricular dysfunction arises in chronic lung disease when chronic hypoxemia and disruption of pulmonary vascular beds contribute to increase ventricular afterload, and is generally defined by hypertrophy with preserved myocardial contractility and cardiac output. Although the exact prevalence is unknown, right ventricular hypertrophy appears to be a common complication of chronic lung disease, and more frequently complicates advanced lung disease. Right ventricular failure is rare, except during acute exacerbations of chronic lung disease or when multiple co-morbidities are present. Treatment is targeted at correcting hypoxia and improving pulmonary gas exchange and mechanics. There are presently no convincing data to support the use of pulmonary hypertension-specific therapies in patients with right ventricular dysfunction secondary to chronic lung disease. PMID:22548815

Silymarin displays anti-inflammatory effects on T-lymphocytes in vitro. The immunomodulatory properties of oral silymarin in vivo in humans with chronic hepatitis C have not previously been characterized. We hypothesized that silymarin would suppress T-cell proliferation and pro-inflammatory cytokine production of virus- and non-virus-specific T-cells while increasing anti-inflammatory IL-10 production in vivo. Patients from one site of the SyNCH-HCV double-masked, placebo-controlled study of oral silymarin in prior interferon non-responders with chronic hepatitis C provided blood samples at baseline and treatment week 20. Mononuclear cells were stimulated with recombinant HCV proteins and controls in 3H-thymidine proliferation assays, IFNγ Elispot and IL-10 Elispot. The frequency of CD4+CD25hi and CD4+foxp3+ regulatory T-cells, serum cytokine levels, serum IP-10 and lymphocyte interferon-stimulated gene expression were also quantified at baseline and week 20. Thirty-two patients were recruited (10; placebo, 11; 420mg three times a day, 11; 700mg three times a day). Serum ALT and HCV RNA titers did not change in any group. HCV-specific CD4+ T-cell proliferation and the frequency of IFNγ– and IL-10-producing T-cells were not significantly changed in silymarin-treated subjects. However, C. albicans-induced T-cell IFNγ and phytohemagglutinin-induced T-cell proliferation were suppressed by silymarin therapy. A trend towards augmentation of interferon-induced ISG15 expression was present in the high-dose silymarin group. While no effect on HCV-specific T-cells was identified, these data confirm that high-dose oral silymarin exerts modest non-specific immunomodulatory effects in vivo. The impact of this anti-inflammatory effect on long-term liver health in chronic hepatitis C merits future clinical investigation. PMID:23730838

The detection, segmentation and quantification of multiple sclerosis (MS) lesions on magnetic resonance images (MRI) has been a very active field for the last two decades because of the urge to correlate these measures with the effectiveness of pharmacological treatment. A myriad of methods has been developed and most of these are non specific for the type of lesions and segment the lesions in their acute and chronic phases together. On the other hand, radiologists are able to distinguish between several stages of the disease on different types of MRI images. The main motivation of the work presented here is to computationally emulate the visual perception of the radiologist by using modeling principles of the neuronal centers along the visual system. By using this approach we are able to detect the lesions in the majority of the images in our population sample. This type of approach also allows us to study and improve the analysis of brain networks by introducing a priori information.

Pentoxifilne (PTX) is a non specific inhibitor of cytokines release, which suppress mainly TNF production. The aim of this study was to evaluate behavioural activity changes in response to acute and chronic nociceptive stimulus. PTX was more effective in neuropathic pain than acute pain model. Use of cytokine inhibitors might offer new strategies of drug-resistant chronic pain treatment.

Experimental autoimmune neuritis (EAN) is a CD4+ T-cell-mediated demyelinating disease of the peripheral nervous system (PNS) and serves as experimental model for human immune-demyelinating neurophathies, especially the Guillain–Barré syndrome. In this study, we examined the effect of recombinant rat interleukin-6 (rrIL-6) on chronic EAN in Lewis rats induced by immunization with P2 peptide 57-81 and Freund’s complete adjuvant (FCA). Nasal administration of rat rIL-6 (1 μg/rat/day) beginning in the initial phase of EAN as a therapeutic agent, decreased the severity and the duration of clinical EAN. Low-grade inflammation and suppression of regional demyelination within the sciatic nerves were seen in rrIL-6-treated rats. Hyporesponsiveness of lymph node T cells, down-regulation of serum tumour necrosis factor-α (TNF-α) and increased levels of P2-specific immunoglobulin G1 (IgG1) antibodies document that nasal administration of rrIL-6 was effective systemically. However, because of the non-specific nature of the treatment and multiple effects of IL-6, more experience and great caution are needed, before nasal administration of IL-6 can be considered as a treatment of human autoimmune demyelinating neurophathies.

Mindfulness Meditation for Fibromyalgia: Mechanistic and Clinical Considerations.

Adler-Neal, Adrienne L; Zeidan, Fadel

2017-09-01

Fibromyalgia is a disorder characterized by widespread pain and a spectrum of psychological comorbidities, rendering treatment difficult and often a financial burden. Fibromyalgia is a complicated chronic pain condition that requires a multimodal therapeutic approach to optimize treatment efficacy. Thus, it has been postulated that mind-body techniques may prove fruitful in treating fibromyalgia. Mindfulness meditation, a behavioral technique premised on non-reactive sensory awareness, attenuates pain and improves mental health outcomes. However, the impact of mindfulness meditation on fibromyalgia-related outcomes has not been comprehensively characterized. The present review delineates the existing evidence supporting the effectiveness and hypothesized mechanisms of mindfulness meditation in treating fibromyalgia-related outcomes. Mindfulness-based interventions premised on cultivating acceptance, non-attachment, and social engagement may be most effective in decreasing fibromyalgia-related pain and psychological symptoms. Mindfulness-based therapies may alleviate fibromyalgia-related outcomes through multiple neural, psychological, and physiological processes. Mindfulness meditation may provide an effective complementary treatment approach for fibromyalgia patients, especially when combined with other reliable techniques (exercise; cognitive behavioral therapy). However, characterizing the specific analgesic mechanisms supporting mindfulness meditation is a critical step to fostering the clinical validity of this technique. Identification of the specific analgesic mechanisms supporting mindfulness-based pain relief could be utilized to better design behavioral interventions to specifically target fibromyalgia-related outcomes.

A simple non-invasive score (Fibrofast, FIB-5) was developed using five routine laboratory tests (ALT, AST, alkaline phosphatase, albumin and platelets count) for the detection of significant hepatic fibrosis in patients with chronic hepatitis C. The FIB-4 index is a non-invasive test for the assessment of liver fibrosis, and a score of ≤1.45 enables the correct identification of patients who have non-significant (F0-1) from significant fibrosis (F2-4), and could avoid liver biopsy. The aim of this study was to compare the performance characteristics of FIB-5 and FIB-4 to differentiate between non-significant and significant fibrosis. A cross-sectional study included 604 chronic HCV patients. All liver biopsies were scored using the METAVIR system. Both FIB-5 and FIB-4 scores were measured and the performance characteristics were calculated using the ROC curve. The performance characteristics of FIB-5 at ≥7.5 and FIB-4 at ≤1.45 for the differentiation between non-significant fibrosis and significant fibrosis were: specificity 94.4%, PPV 85.7%, and specificity 54.9%, PPV 55.7% respectively. FIB-5 score at the new cutoff is superior to FIB-4 index for the differentiation between non-significant and significant fibrosis.

Multiple chemical sensitivity (MCS) is a multisystem disorder of controversial etiology, affecting some subjects when exposed to chemicals at no harmful concentrations. The objective of this paper is to describe the epidemiological, clinical and psychological features of a sample of patients with MCS for further specific group treatment. Descriptive study of patients diagnosed with MCS in a toxicology unit. We administered the Quick Environmental Exposure and Sensitivity Inventory, the structured interview SCID-II, the anxiety scale HAS and the type A personality test, PCTA. Seventy-three patients were included. The mean age was 52,6 years (range 33-77; SD 9.29). Sixty-six were females (90.4%). Fifty-three percent were classified as i-ii and ii grade. Sixty-one patients (83%) presented some type of comorbidity, mainly chronic pain, fibromyalgia and chronic fatigue. They exhibited higher levels of anxiety (average score of 19.2), prevalence of phobic-avoidant traits of personality and type A behavior in 31.1%. MCS affects middle-aged women with comorbidities (chronic pain, fibromyalgia and chronic fatigue) and high anxiety and avoidance behaviors. This preliminary analysis should help provide a specific therapeutic approach to these patients. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Environmental fungi have been linked to TH2 cell-related airway inflammation and the TH2-associated chronic airway diseases asthma, chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), and allergic fungal rhinosinusitis (AFRS), but whether these organisms participate directly or indirectly in disease pathology remains unknown. To determine the frequency of fungus isolation and fungus-specific immunity in patients with TH2-associated and non-TH2-associated airway disease. Sinus lavage fluid and blood were collected from sinus surgery patients (n = 118) including patients with CRSwNP, patients with CRS without nasal polyps, patients with AFRS, and non-CRS/nonasthmatic control patients. Asthma status was determined from medical history. Sinus lavage fluids were cultured and directly examined for evidence of viable fungi. PBMCs were restimulated with fungal antigens in an enzyme-linked immunocell spot assay to determine total memory fungus-specific IL-4-secreting cells. These data were compared with fungus-specific IgE levels measured from plasma by ELISA. Filamentous fungi were significantly more commonly cultured in patients with TH2-associated airway disease (asthma, CRSwNP, or AFRS: n = 68) than in control patients with non-TH2-associated disease (n = 31): 74% vs 16%, respectively (P < .001). Both fungus-specific IL-4 enzyme-linked immunocell spot (n = 48) and specific IgE (n = 70) data correlated with TH2-associated diseases (sensitivity 73% and specificity 100% vs 50% and 77%, respectively). The frequent isolation of fungi growing directly within the airways accompanied by specific immunity to these organisms only in patients with TH2-associated chronic airway diseases suggests that fungi participate directly in the pathogenesis of these conditions. Efforts to eradicate airway fungi from the airways should be considered in selected patients. Copyright © 2014 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc.

2017-01-01

Background Cervical range of motion (ROM) is commonly assessed in clinical practice and research. In a previous study we decomposed active cervical sagittal ROM into contributions from lower and upper levels of the cervical spine and found level- and direction-specific impairments in women with chronic non-specific neck pain. The present study aimed to validate these results and investigate if the specific impairments can be explained by the neutral posture (defining zero flexion/extension) or a movement strategy to avoid large gravitationally induced torques on the cervical spine. Methods Kinematics of the head and thorax was assessed in sitting during maximal sagittal cervical flexion/extension (high torque condition) and maximal protraction (low torque condition) in 120 women with chronic non-specific neck pain and 40 controls. We derived the lower and upper cervical angles, and the head centre of mass (HCM), from a 3-segment kinematic model. Neutral head posture was assessed using a standardized procedure. Findings Previous findings of level- and direction-specific impairments in neck pain were confirmed. Neutral head posture was equal between groups and did not explain the direction-specific impairments. The relative magnitude of group difference in HCM migration did not differ between high and low torques conditions, lending no support for our hypothesis that impairments in sagittal ROM are due to torque avoidance behaviour. Interpretation The direction- and level-specific impairments in cervical sagittal ROM can be generalised to the population of women with non-specific neck pain. Further research is necessary to clarify if torque avoidance behaviour can explain the impairments. PMID:28099504

Preventing and ameliorating chronic conditions has long been a priority in the United States; however, the increasing recognition that people often have multiple chronic conditions (MCC) has added a layer of complexity with which to contend. The objective of this study was to present the prevalence of MCC and the most common MCC dyads/triads by selected demographic characteristics. We used respondent-reported data from the 2010 National Health Interview Survey (NHIS) to study the US adult civilian noninstitutionalized population aged 18 years or older (n = 27,157). We categorized adults as having 0 to 1, 2 to 3, or 4 or more of the following chronic conditions: hypertension, coronary heart disease, stroke, diabetes, cancer, arthritis, hepatitis, weak or failing kidneys, chronic obstructive pulmonary disease, or current asthma. We then generated descriptive estimates and tested for significant differences. Twenty-six percent of adults have MCC; the prevalence of MCC has increased from 21.8% in 2001 to 26.0% in 2010. The prevalence of MCC significantly increased with age, was significantly higher among women than men and among non-Hispanic white and non-Hispanic black adults than Hispanic adults. The most common dyad identified was arthritis and hypertension, and the combination of arthritis, hypertension, and diabetes was the most common triad. The findings of this study contribute information to the field of MCC research. The NHIS can be used to identify population subgroups most likely to have MCC and potentially lead to clinical guidelines for people with more common MCC combinations. PMID:23618545

Summary The hallmark of chronic viral infections is a progressive exhaustion of antigen specific CD8+ T cells that leads to persisting viral replication. It is generally believed that exhaustion is a consequence of the accumulation of multiple inhibitory receptors on CD8+ T cells that makes them dysfunctional. Here we show that during human chronic HIV-1 infection a CD8+ T cell positive costimulatory pathway mediated by DNAM-1 is also disrupted. Thus, DNAM-1 downregulation on CD8+ T cells aggravates the impairment of CTL effector function in chronic HIV-1 infection. PMID:20201043

A shifting pattern from communicable diseases to the chronic noncommunicable diseases and increased life expectancy are being sensed throughout the world. Aged populations with multiple chronic diseases come up with their unique needs and require specific attention to be challenged by the health systems. Neglected orodental facts among the elders and the dearth of specific designated undergraduate and postgraduate courses of geriatric dentistry in Iran inevitably adversely affect the delivery of appropriate dental care service to elders by untrained dentists. In this article, a proposal for academic geriatric dentistry courses in Iran is introduced and highlighted with regards to elders' special needs.

To evaluate the cost-effectiveness of manual therapy according to the Utrecht School (MTU) in comparison with physiotherapy (PT) in sub-acute and chronic non-specific neck pain patients from a societal perspective. An economic evaluation was conducted alongside a 52-week randomized controlled trial, in which 90 patients were randomized to the MTU group and 91 to the PT group. Clinical outcomes included perceived recovery (yes/no), functional status (continuous and yes/no), and quality-adjusted life-years (QALYs). Costs were measured from a societal perspective using self-reported questionnaires. Missing data were imputed using multiple imputation. To estimate statistical uncertainty, bootstrapping techniques were used. After 52 weeks, there were no significant between-group differences in clinical outcomes. During follow-up, intervention costs (β:€-32; 95 %CI: -54 to -10) and healthcare costs (β:€-126; 95 %CI: -235 to -32) were significantly lower in the MTU group than in the PT group, whereas unpaid productivity costs were significantly higher (β:€186; 95 %CI:19-557). Societal costs did not significantly differ between groups (β:€-96; 95 %CI:-1975-2022). For QALYs and functional status (yes/no), the maximum probability of MTU being cost-effective in comparison with PT was low (≤0.54). For perceived recovery (yes/no) and functional status (continuous), a large amount of money must be paid per additional unit of effect to reach a reasonable probability of cost-effectiveness. From a societal perspective, MTU was not cost-effective in comparison with PT in patients with sub-acute and chronic non-specific neck pain for perceived recovery, functional status, and QALYs. As no clear total societal cost and effect differences were found between MTU and PT, the decision about what intervention to administer, reimburse, and/or implement can be based on the preferences of the patient and the decision-maker at hand.

Magnetic resonance (MR) imaging plays an important role in the diagnosis and staging of acute and chronic pancreatitis and may represent the best imaging technique in the setting of pancreatitis due to its unmatched soft tissue contrast resolution as well as non-ionizing nature and higher safety profile of intravascular contrast media, making it particularly valuable in radiosensitive populations such as pregnant patients, and patients with recurrent pancreatitis requiring multiple follow-up examinations. Additional advantages include the ability to detect early forms of chronic pancreatitis and to better differentiate adenocarcinoma from focal chronic pancreatitis. This review addresses new trends in clinical pancreatic MR imaging emphasizing its role in imaging all types of acute and chronic pancreatitis, pancreatitis complications and other important differential diagnoses that mimic pancreatitis.

Current approach to the treatment of chronic myeloid leukaemia.

PubMed

Pasic, Ivan; Lipton, Jeffrey H

2017-04-01

Of all the cancers, chronic myeloid leukaemia (CML) has witnessed the most rapid evolution of the therapeutic milieu in recent decades. The introduction of tyrosine kinase inhibitors (TKIs) as a therapeutic option has profoundly changed patient experience and outcome. The availability of multiple new highly effective therapies has increasingly underscored the importance of a good understanding of the underlying pathophysiological basis in CML, as well as patient-specific factors in choosing the right treatment for every individual. The treatment of CML has migrated in many jurisdictions from the office of a highly specialized malignant hematologist to the general hematologist or even a general practitioner. The goal of this review is to offer an overview of the modern approach to the treatment of CML, with an emphasis on chronic phase (CP) CML, including both TKI-based therapies such as imatinib, dasatinib, nilotinib, bosutinib and ponatinib, and non-TKI medications, such as omacetaxine. We discuss evidence behind each drug, most common and material adverse reactions and outline how this information can be used in selecting the right drug for the right patient. We also discuss evidence as it relates to other therapies, including stem cell transplant (SCT), and patients in accelerated (AP) and blastic phase (BP). Copyright © 2017 Elsevier Ltd.

On average, adults aged 60 years or older have 2.2 chronic diseases, contributing to the over 60 million Americans with multiple morbidities. We aimed to understand the financial implications of the most frequent multiple morbidities among older adults. We analyzed Health and Retirement Study data, determining out-of-pocket medical expenses from 1998 and 2002 separately and examining differences in the impact of multiple-morbidity constellations on these expenses. We paid particular attention to the most common disease constellations - hypertension, arthritis, and heart disease. An increasing prevalence of multiple morbidity (58% compared with 70% of adults had two or more chronic conditions in 1998 and 2002, respectively) was accompanied by escalating out-of-pocket expenditures (2,164 dollars in 1998, increasing by 104% to 3,748 dollars in 2002). Individuals with two, three, and four chronic conditions had health care expenditure increases of 41%, 85%, and 100%, respectively, over 4 years. Such patterns were particularly noticeable among the oldest old, those with higher educational attainment, and women, although having supplementary health insurance or Medicaid mitigated these expenses. Finally, there were significant differences in out-of-pocket expenditure levels among the multiple-morbidity combinations. Increasing rates of multiple morbidities in conjunction with escalating health care costs and stable or declining incomes among elders warrant creative attention from providers, researchers, and policy makers. Further understanding how specific multiple-morbidity constellations impact out-of-pocket spending moves us closer to effective interventions to support vulnerable elders.

Fibromyalgia and chronic fatigue syndrome in children.

2012-04-01

Fibromyalgia (FM) is characterized by widespread persistent pain and the presence of multiple discrete tender points. Chronic fatigue syndrome (CFS) is a syndrome characterized by debilitating fatigue associated with a variable number of non-specific complaints. Because neither condition had necessarily been recognized in children until recently, those patients have been treated as having school refusal without being diagnosed as having either syndrome. There is a considerable overlap of clinical symptoms between these two syndromes. It is therefore controversial as to whether these syndromes have the same pathogenesis or not. The aim of the present study was to clarify the relationship between these syndromes in children. Fifteen patients with FM and 21 patients with CFS were investigated both clinically and immunologically. Immunological assessments included thorough analysis of autoantibodies using several techniques. Anti-nuclear antibody titers were higher and the prevalence of anti-Sa antibody was far more frequent in CFS patients than in FM patients. CFS and FM are different from each other at least in childhood, from an immunological aspect, although some patients could have both conditions. © 2011 The Authors.

Background: Kinesio Taping ® has been widely used in clinical practice. However, it is unknown whether this type of tape is more effective than placebo taping in patients with chronic lower back pain. Objective: To compare the effectiveness of Kinesio Taping ® in patients with chronic non-specific low back pain against a placebo tape and a control group. Method: This is a 3-arm, randomized controlled trial with a blinded assessor. Sixty patients with chronic non-specific low back pain were randomized into one of the three groups: Kinesio Taping ® group (n=20), Micropore® (placebo) group (n=20) and control group (n=20). Patients allocated to both the Kinesio Taping ® group and the placebo group used the different types of tape for a period of 48 hours. The control group did not receive any intervention. The outcomes measured were pain intensity (measured by an 11-point numerical rating scale) and disability (measured by the 24-item Roland Morris Disability Questionnaire). A blinded assessor measured the outcomes at baseline, 48 hours and 7 days after randomization. Results: After 48 hours, there was a statistically significant difference between the Kinesio Taping ® group versus the control group (mean between-group difference = -3.1 points, 95% CI=-5.2 to -1.1, p=0.003), but no difference when compared to the placebo group (mean between-group difference= 1.9 points, 95% CI=-0.2 to 3.9, p=0.08). For the other outcomes no differences were observed. Conclusions: The Kinesio Taping ® is not better than placebo (Micropore®) in patients with chronic low back pain. PMID:26647750

Background Although 1-in-5 adults have multiple (≥2) chronic conditions, limited attention has been given to the association between multiple chronic conditions and employment. Methods Cross-sectional data (2011 National Health Interview Survey) and multivariate regression analyses were used to examine the association among multiple chronic conditions, employment, and labor force outcomes for U.S. adults aged 18–64 years, controlling for covariates. Results Among U.S. adults aged 18–64 years (unweighted n=25,458), having multiple chronic conditions reduced employment probability by 11%–29%. Some individual chronic conditions decreased employment probability. Among employed adults (unweighted n=16,096), having multiple chronic conditions increased the average number of work days missed due to injury/illness in the past year by 3–9 days. Conclusions Multiple chronic conditions are be a barrier to employment and increase the number of work days missed, placing affected individuals at a financial disadvantage. Researchers interested in examining consequences of multiple chronic conditions should give consideration to labor force outcomes. PMID:26103096

Although allogeneic stem cell transplantation is not a standard therapy for multiple myeloma, some patients can benefit from this intense therapy. There are few reports on outcomes after umbilical cord blood transplantation in multiple myeloma, and investigation of this procedure is warranted. We retrospectively analyzed 95 patients, 85 with multiple myeloma and 10 with plasma cell leukemia, receiving single or double umbilical cord blood transplantation from 2001 to 2013. Median follow up was 41 months. The majority of patients received a reduced intensity conditioning. The cumulative incidence of neutrophil engraftment was 97%±3% at 60 days, and that of 100-day acute graft-versus-host disease grade II-IV was 41%±5%. Chronic graft-versus-host disease at two years was 22%±4%. Relapse and non-relapse mortality was 47%±5% and 29%±5% at three years, respectively. Three-year progression-free survival and overall survival were 24%±5% and 40%±5%, respectively. Anti-thymocyte globulin was associated with decreased incidence of acute graft-versus-host disease, higher non-relapse mortality, decreased overall and progression-free survival. Patients with high cytogenetic risk had higher relapse, and worse overall and progression-free survival. In conclusion, umbilical cord blood transplantation is feasible for multiple myeloma patients.

A Systematic Review of the Effects of Exercise and Physical Activity on Non-Specific Chronic Low Back Pain

PubMed Central

Gordon, Rebecca; Bloxham, Saul

2016-01-01

Back pain is a major health issue in Western countries and 60%–80% of adults are likely to experience low back pain. This paper explores the impact of back pain on society and the role of physical activity for treatment of non-specific low back pain. A review of the literature was carried out using the databases SPORTDiscuss, Medline and Google Scholar. A general exercise programme that combines muscular strength, flexibility and aerobic fitness is beneficial for rehabilitation of non-specific chronic low back pain. Increasing core muscular strength can assist in supporting the lumbar spine. Improving the flexibility of the muscle-tendons and ligaments in the back increases the range of motion and assists with the patient’s functional movement. Aerobic exercise increases the blood flow and nutrients to the soft tissues in the back, improving the healing process and reducing stiffness that can result in back pain. PMID:27417610

Multiple sclerosis (MS) is a chronic progressive inflammatory disease of the central nervous system (CNS) and the major cause of non-traumatic disability in young adults. Fatigue is a frequent symptom reported by the majority of MS patients during their disease course and drastically affects their quality of life. Despite its significant prevalence and impact, the underlying pathophysiological mechanisms are not well elucidated. MS fatigue is still considered the result of multifactorial and complex constellations, and is commonly classified into “primary” fatigue related to the pathological changes of the disease itself, and “secondary” fatigue attributed to mimicking symptoms, comorbid sleep and mood disorders, and medications side effects. Radiological, physiological, and endocrine data have raised hypotheses regarding the origin of this symptom, some of which have succeeded in identifying an association between MS fatigue and structural or functional abnormalities within various brain networks. Hence, the aim of this work is to reappraise the neural correlates of MS fatigue and to discuss the rationale for the emergent use of noninvasive brain stimulation (NIBS) techniques as potential treatments. This will include a presentation of the various NIBS modalities and a suggestion of their potential mechanisms of action in this context. Specific issues related to the value of transcranial direct current stimulation (tDCS) will be addressed. PMID:26648845

Concurrent Social Disadvantages and Chronic Inflammation: The Intersection of Race and Ethnicity, Gender, and Socioeconomic Status.

Disadvantaged social statuses, such as being female, poor, or a minority, are associated with increased psychosocial stress and elevated circulating concentrations of C-reactive protein, a biomarker of chronic inflammation and indicator of cardiovascular health. Individuals' experience of embodying psychosocial stress revolves around the multiplicative effects of concurrent gender, socioeconomic, and racial and ethnic identities. This study expands on prior research by examining chronic inflammation at the intersection of race and ethnicity, gender, socioeconomic status, and age group to understand which demographic subgroups in society are most vulnerable to the cumulative effects of social disadvantage. Using data from the National Health and Nutrition Examination Survey 2007-2010, the findings reveal inflammation disparities between non-poor whites and the following demographic subgroups, net of sociodemographic and biological factors: young poor Hispanic women, young poor white men, young poor and non-poor Hispanic men, middle-aged poor and non-poor black women, middle-aged poor and non-poor black men, and middle-aged poor Hispanic men. Disparities in inflammation on account of social disadvantage are most evident among those aged 45-64 years and diminish for those 65 and older in both men and women.

Introduction Generic health-related quality of life (HRQOL) patient-reported outcome measures have been used in patients with chronic immune-mediated polyneuropathies. We have created a disease-specific HRQOL instrument. Methods and Results The 15-item chronic acquired polyneuropathy patient-reported index (CAP-PRI) was developed and validated in multiple steps. Items were initially generated through patient and specialist input. The performance of the preliminary 20 items was analyzed from a prospective, 5-center study involving chronic immune-mediated polyneuropathy patients. Data analysis suggested modification to a 15-item scale with 3 response categories, rather than 5. The final CAP-PRI was then validated in another prospective, 5-center study. The CAP-PRI appeared to be a unidimensional outcome measure that fits the Rasch Partial Credit Model in our multicenter cohort. It correlated appropriately with the outcome measures commonly used in this patient population. Discussion The CAP-PRI is a simple, easy, disease-specific HRQOL measure that appears to be useful for clinical care and possibly also for clinical trials. PMID:26600438

Non-organ-specific autoantibodies (NOSAs) are frequently found in the sera of patients with Hepatitis C Virus (HCV) infection. However, no conclusive answers have been produced concerning the clinical relevance of these antibodies. To determine whether a relationship might exist between the presence of NOSA and the severity of liver disease in chronic hepatitis C. 186 treatment-naïve chronic hepatitis C patients were studied consecutively for autoantibodies. Liver biopsies were analyzed according to the Metavir score. NOSAs were present in 75 patients (40%). Anti-nuclear antibodies were found in 32% of patients (speckled pattern), anti-smooth muscle in 15% without F-actin specificity, anti-mitochondria in 0.5%, and anti-LKM1 in 0.5%, respectively. No liver-cytosol1 or soluble liver antigen antibodies were detected. There was a highly significant correlation between the positivity of NOSA and the degree of inflammation and hepatocellular injury (p = 0.001) and also with the degree of fibrosis (p < 0.0001). The presence of NOSA was associated with higher aspartate aminotransferase, gamma-glutamyl-transpeptidase, gamma-globulin and immunoglobulin G levels. By contrast, no differences were observed regarding age, gender, route of infection, duration of disease, HCV genotypes or viral load. NOSAs were associated with the most severe forms of chronic HCV infections.

This study is aimed to identify the association between regimen difficulty and medication non-adherence among patients with chronic conditions and testing the interaction effects of gender and age on the same. It was a cross-sectional study conducted among 479 outpatients from India. Convenience sampling method was used. Multiple regression analyses were performed to find the predictors of non-adherence and to test interaction effects. Regimen difficulty predicted medication non-adherence. The patient's gender and age have interaction effects on the relationship between regimen difficulty and medication non-adherence.

Background T-cell exhaustion seems to play a critical role in CD8+ T-cell dysfunction during chronic viral infections. However, up to now little is known about the mechanisms underlying CD4+ T-cell dysfunction during chronic hepatitis B virus (CHB) infection and the role of inhibitory molecules such as programmed death 1 (PD-1) for CD4+ T-cell failure. Methods The expression of multiple inhibitory molecules such as PD-1, CTLA-4, TIM-3, CD244, KLRG1 and markers defining the grade of T-cell differentiation as CCR7, CD45RA, CD57 and CD127 were analyzed on virus-specific CD4+ T-cells from peripheral blood using a newly established DRB1*01-restricted MHC class II Tetramer. Effects of in vitro PD-L1/2 blockade were defined by investigating changes in CD4+ T-cell proliferation and cytokine production. Results CD4+ T-cell responses during chronic HBV infection was characterized by reduced Tetramer+CD4+ T-cell frequencies, effector memory phenotype, sustained PD-1 but low levels of CTLA-4, TIM-3, KLRG1 and CD244 expression. PD-1 blockade revealed individualized patterns of in vitro responsiveness with partly increased IFN-γ, IL-2 and TNF-α secretion as well as enhanced CD4+ T-cell expansion almost in treated patients with viral control. Conclusion HBV-specific CD4+ T-cells are reliably detectable during different courses of HBV infection by MHC class II Tetramer technology. CD4+ T-cell dysfunction during chronic HBV is basically linked to strong PD-1 upregulation but absent coregulation of multiple inhibitory receptors. PD-L1/2 neutralization partly leads to enhanced CD4+ T-cell functionality with heterogeneous patterns of CD4+ T-cell rejunivation. PMID:25144233

The management of patients with chronic respiratory diseases affected by difficult to treat infections has become a challenge in clinical practice. Conditions such as cystic fibrosis (CF) and non-CF bronchiectasis require extensive treatment strategies to deal with multidrug resistant pathogens that include Pseudomonas aeruginosa, Methicillin-resistant Staphylococcus aureus, Burkholderia species and non-tuberculous Mycobacteria (NTM). These challenges prompted scientists to deliver antimicrobial agents through the pulmonary system by using inhaled, aerosolized or nebulized antibiotics. Subsequent research advances focused on the development of antibiotic agents able to achieve high tissue concentrations capable of reducing the bacterial load of difficult-to-treat organisms in hosts with chronic respiratory conditions. In this review, we focus on the evidence regarding the use of antibiotic therapies administered through the respiratory system via inhalation, nebulization or aerosolization, specifically in patients with chronic respiratory diseases that include CF, non-CF bronchiectasis and NTM. However, further research is required to address the potential benefits, mechanisms of action and applications of inhaled antibiotics for the management of difficult-to-treat infections in patients with chronic respiratory diseases.

To assess the levels of perceived acute and chronic racial and non-racial discrimination in South Africa, their association with health, and the extent to which they contribute to racial differences in physical and mental health, data were used from a national probability sample of adults, the South African Stress and Health Study (SASH). All Black groups in South Africa (African, Coloured and Indian) were two to four times more likely than Whites to report acute and chronic experiences of racial discrimination. Africans and Coloureds report higher levels of ill health than Whites, but acute and chronic racial discrimination were unrelated to ill health and unimportant in accounting for racial differences in self-rated health. In contrast, all Black groups had higher levels of psychological distress than Whites, and perceived chronic discrimination was positively associated with distress. Moreover, these experiences accounted for some of the residual racial differences in distress after adjustment for socioeconomic status. Our main findings indicate that, in a historically racialized society, perceived chronic racial and especially non-racial discrimination acts independently of demographic factors, other stressors, psychological factors (social desirability, self-esteem and personal mastery), and multiple SES indicators to adversely affect mental health.

An increasing proportion of healthcare resources in the United States are directed toward an expanding group of complex and multimorbid patients. Federal stakeholders have called for new models of care to meet the needs of these patients. Minimally Disruptive Medicine (MDM) is a theory-based, patient-centered, and context-sensitive approach to care that focuses on achieving patient goals for life and health while imposing the smallest possible treatment burden on patients’ lives. The MDM Care Model is designed to be pragmatically comprehensive, meaning that it aims to address any and all factors that impact the implementation and effectiveness of care for patients with multiple chronic conditions. It comprises core activities that map to an underlying and testable theoretical framework. This encourages refinement and future study. Here, we present the conceptual rationale for and a practical approach to minimally disruptive care for patients with multiple chronic conditions. We introduce some of the specific tools and strategies that can be used to identify the right care for these patients and to put it into practice. PMID:27417747

The clinical importance of HLA-specific antibodies for organ allograft outcome is well established. In the past few years, there has been an increasing interest in non-HLA antigens as targets of injury in organ transplant recipients. This increased interest has been spurred by the fact that HLA-identical kidney transplants also undergo immunological rejections. Polymorphisms within non-HLA genes associated with evoking an immune response to alloantigens are currently being studied for their association with transplant outcome. Non-HLA antigens, such as the polymorphic MHC class I-related chain A (MICA), expressed on endothelial cells have been implicated in the pathogenesis of hyperacute, acute and chronic organ allograft rejections. Use of endothelial cells as targets may clarify the specificities of other clinically relevant non-HLA antibodies in graft rejections. This review summarizes past and current knowledge of the clinical importance and specificities of non-HLA antibodies, and mechanisms by which these antibodies may contribute to graft destruction in clinical transplantation. The aims of current research into the role of non-HLA antigens and their genetics in predicting outcome are to develop an improved insight into the basic science of transplantation and to develop a risk or prognostic index for use in the clinical setting. Non-HLA antibody responses are receiving increasing interest in acute and chronic rejection and specificity, affinity, and pathogenicity need to be investigated to estimate their contribution. Undoubtedly, this will continue to be an area of interest in terms of fully understanding the role of non-HLA antigens as targets of immune-mediated injury and the potential for clinical intervention.

Objectives Multimorbidity is common in the older population, but the impact of combinations of chronic conditions on disability and quality of life (QoL) is not well known. This analysis explores the effect of specific combinations of chronic diseases on disability, QoL and self-rated health (SRH). Design We used data from two population representative cross-sectional studies, the Northern Ireland Health and Social Wellbeing Survey (NIHSWS) 2005 and the Survey of Lifestyle, Attitudes and Nutrition (SLAN) 2007 (conducted in the Republic of Ireland). Setting Randomly selected community-living participants were interviewed at home. Participants A total of 6159 participants aged 50 years and older were included in the analysis. Outcome measures Chronic conditions were classified as cardiovascular disease, chronic pain, diabetes or respiratory disease. Interaction terms estimated by logistic regression were used to examine the effects of multiple chronic conditions on disability, SRH and QoL. Results Each chronic condition group was correlated with each of the others after adjusting for sociodemographic factors. Those from Northern Ireland were more likely to report a limitation in daily activities (45%) compared to those from the Republic of Ireland (21%). Each condition had an independent effect on disability, SRH and QoL, and those with multiple chronic conditions reported the worst outcomes. However, there were no statistically significant positive interactions between chronic condition groups with respect to any outcome. Conclusions Chronic conditions affect individuals largely independent of each other with respect to their effect on disability, SRH and QoL. However, a significant proportion of the population aged 50 years and over across the island of Ireland lives with multimorbidity, and this group is at the highest risk of disability, poor SRH and poor QoL.

The ageing population worldwide is increasingly acquiring multiple chronic diseases. The complex management of chronic diseases could be improved with electronic health records (EHRs) tailored to chronic disease care, but most EHRs in use today do not adequately support longitudinal data management. A key aspect of chronic disease management is that it takes place over long periods, but the way that most EHRs display longitudinal data makes it difficult to trend changes over time and slows providers as they review each patient's unique course. We present five clinical scenarios illustrating longitudinal data needs in complex chronic disease management. These scenarios may function as example cases for software development. For each scenario, we describe and illustrate improvements in temporal data views. Two potential solutions are visualisation for numerical data and disease-oriented text summaries for non-numerical data. We believe that development and widespread implementation of improved temporal data views in EHRs will improve the efficiency and quality of chronic disease management in primary care.

To describe the radiological and clinical features of adult non-puerperal mastitis and to determine the most accurate method of preventing unnecessary surgical procedures. Clinical and imaging findings were retrospectively reviewed in 51 females with non-puerperal mastitis, which was confirmed by biopsy/surgical pathology. All 51 patients had pre-operative MRI; 45 patients also had sonograms and 25 also had mammograms, pre-operatively. Of the 51 cases with non-puerperal mastitis, 94.1% (48/51) were confirmed as having acute or chronic inflammation, and the other 3 had plasma cell mastitis; areola papillaris inflammation was found in 39.2% (20/51) of the cases. Overall, 6 of the 25 cases that were examined with mammography and 2 of the 45 cases that were examined with sonography appeared normal, but all 51 lesions were positively identified on MRI. Asymmetrical density (12/25) on mammograms and solitary or separated/contiguous, clustered, hypoechoic mass-like lesions (31/45) on ultrasound were the most common signs of non-puerperal mastitis. On enhanced MRI, 90.2% (46/51) of patients showed non-mass-like enhanced lesions. Multiple regional enhancements in the pattern of distribution (32/46) and separated or contiguous, clustered, rim-like enhancements in the pattern of internal enhancement (29/46) were the most common manifestations in non-mass-like enhanced lesions. Of the 51 patients, mastitis Type 1 and Type 2 in the time-signal intensity curve were detected in 47.1% and 51.0% of the patients, respectively. The breast imaging reporting and data system categories with the highest number of patients were Category 0 (9/25) on mammography, Category 4a on sonography (18/45) and Category 4a on MRI (29/51). The findings from mammography and ultrasound are non-specific; therefore, using MR can be helpful in the diagnosis, especially in the presence of non-mass-like enhancements that are multiple, regional, separated, or contiguous, clustered and rim-like. Mastitis is often neglected because of the lack of typical clinical signs and symptoms. This study has assessed and described the clinical features and imaging findings of adult non-puerperal mastitis on mammograms, sonograms and MRI and found that MRI is more specific in the diagnosis of disease.

Month-season of birth (M-SOB) is a risk factor in multiple chronic diseases, including multiple sclerosis (MS), where the lowest and greatest risk of developing MS coincide with the lowest and highest birth rates, respectively. To determine whether M-SOB effects in such chronic diseases as MS can be experimentally modeled, we examined the effect of M-SOB on susceptibility of C57BL/6J mice to experimental autoimmune encephalomyelitis (EAE). As in MS, mice that were born during the M-SOB with the lowest birth rate were less susceptible to EAE than mice born during the M-SOB with the highest birth rate. We also show that the M-SOB effect on EAE susceptibility is associated with differential production of multiple cytokines/chemokines by neuroantigen-specific T cells that are known to play a role in EAE pathogenesis. Taken together, these results support the existence of an M-SOB effect that may reflect seasonally dependent developmental differences in adaptive immune responses to self-antigens independent of external stimuli, including exposure to sunlight and vitamin D. Moreover, our documentation of an M-SOB effect on EAE susceptibility in mice allows for modeling and detailed analysis of mechanisms that underlie the M-SOB effect in not only MS but in numerous other diseases in which M-SOB impacts susceptibility.-Reynolds, J.

Background Patients with chronic liver disease often suffer from unspecific symptoms and report severe impairment in the quality of life. The underlying mechanisms are multifactorial and include disease-specific but also liver related causes. The current analysis evaluated the association of hepatocellular apoptosis in non-viral chronic liver disease and health-related quality of life (HRQL). Furthermore we examined factors, which influence patient's physical and mental well-being. Methods A total of 150 patients with non-infectious chronic liver disease were included between January 2014 and June 2015. The German version of the Chronic Liver Disease Questionnaire (CLDQ-D), a liver disease specific instrument to assess HRQL, was employed. Hepatocellular apoptosis was determined by measuring Cytokeratin 18 (CK18, M30 Apoptosense ELISA). Results Female gender (5.24 vs. 5.54, p = 0.04), diabetes mellitus type II (4.75 vs. 5.46, p<0.001) and daily drug intake (5.24 vs. 6.01, p = 0.003) were associated with a significant impairment in HRQL. HRQL was not significantly different between the examined liver diseases. Levels of CK18 were the highest in patients with NASH compared to all other disease entities (p<0.001). Interestingly, CK18 exhibited significant correlations with obesity (p<0.001) and hyperlipidemia (p<0.001). In patients with cirrhosis levels of CK18 correlated with the MELD score (r = 0.18, p = 0.03) and were significantly higher compared to patients without existing cirrhosis (265.5 U/l vs. 186.9U/l, p = 0.047). Additionally, CK18 showed a significant correlation with the presence and the degree of hepatic fibrosis (p = 0.003) and inflammation (p<0.001) in liver histology. Finally, there was a small negative association between CLDQ and CK18 (r = -0.16, p = 0.048). Conclusion Different parameters are influencing HRQL and CK18 levels in chronic non-viral liver disease and the amount of hepatocellular apoptosis correlates with the impairment in HRQL in chronic non-viral liver diseases. These findings support the role of liver-protective therapies for the improvement of the quality of life in chronic liver disease. PMID:26990427

Background : Alongside the dramatic increase of older adults in the United States (U.S.), it is projected that the aging population residing in rural areas will continue to grow. As the prevalence of chronic diseases and multiple chronic conditions among adults continues to rise, there is additional need for evidence-based interventions to assist the aging population to improve lifestyle behaviors, and self-manage their chronic conditions. The purpose of this descriptive study was to identify the geospatial dissemination of Chronic Disease Self-Management Education (CDSME) Programs across the U.S. in terms of participants enrolled, workshops delivered, and counties reached. These dissemination characteristics were compared across rurality designations (i.e., metro areas; non-metro areas adjacent to metro areas, and non-metro areas not adjacent to metro areas). Methods : This descriptive study analyzed data from a national repository including efforts from 83 grantees spanning 47 states from December 2009 to December 2016. Counts were tabulated and averages were calculated. Results : CDSME Program workshops were delivered in 56.4% of all U.S. counties one or more times during the study period. Of the counties where a workshop was conducted, 50.5% were delivered in non-metro areas. Of the 300,640 participants enrolled in CDSME Programs, 12% attended workshops in non-metro adjacent areas, and 7% attended workshops in non-metro non-adjacent areas. The majority of workshops were delivered in healthcare organizations, senior centers/Area Agencies on Aging, and residential facilities. On average, participants residing in non-metro areas had better workshop attendance and retention rates compared to participants in metro areas. Conclusions : Findings highlight the established role of traditional organizations/entities within the aging services network, to reach remote areas and serve diverse participants (e.g., senior centers). To facilitate growth in rural areas, technical assistance will be needed. Additional efforts are needed to bolster partnerships (e.g., sharing resources and knowledge), marketing (e.g., tailored material), and regular communication among stakeholders.

A risk association has been observed between non-O blood groups and pancreatic adenocarcinoma. Chronic pancreatitis also increases risk for pancreatic cancer, raising questions as to whether non-O blood groups are a risk for chronic pancreatitis and whether the pathophysiologic pathways are linked. Our goal was to determine whether ABO blood group may affect the risk of chronic pancreatitis. The study cohort included chronic pancreatitis patients (n = 499) and healthy controls (n = 631) from the North American Pancreatitis Study 2 study. Genotyping was performed using Sequenom assay of rs8176746 A/C and rs505922 C/T to classify participants into ABO blood groups. O blood group was nonsignificantly more common among cases (44.7% vs 42.0%; P = 0.36), particularly among cases with alcohol-related chronic pancreatitis (49.3% vs 42%; P = 0.060). Alcoholic patients without coexisting high-risk PRSS1, CFTR, or SPINK1 variants had a significant overrepresentation of O blood type when compared with controls (odds ratio, 1.54; 95% confidence interval, 1.09-2.17; P = 0.01). A, B, and AB blood groups were not associated with a greater likelihood of having chronic pancreatitis and may decrease the risk of chronic pancreatitis in individuals who are very heavy drinkers. These results suggest that the mechanism linking non-O blood type with pancreatic pathology is specific to carcinogenesis.

To assess the effectiveness of 12 weeks of Pilates practice on disability, pain and kinesiophobia in patients with chronic non-specific low back pain. This is a randomized controlled trial. This study was conducted in the university laboratory. A total of 64 participants with chronic non-specific low back pain were included. Participants were randomly allocated to intervention group consisted in Pilates intervention during 12 weeks ( n = 32) or control group who received no treatment ( n = 32). Disability, pain and kinesiophobia were assessed by Roland Morris Disability Questionnaire, visual analogue scale and Tampa Scale of Kinesiophobia, respectively. Measurements were performed at baseline, at 6 and 12 weeks after study completion. There were significant differences between groups with observed improvement in Pilates intervention group in all variables after treatment ( P < 0.001). Major changes on disability and kinesiophobia were observed at six weeks of intervention with no significant difference after 12 weeks ( P < 0.001). Mean changes of the intervention group compared with the control group were 4.00 (0.45) on the Roland Morris Disability Questionnaire and 5.50 (0.67) in the Tampa Scale of Kinesiophobia. Pain showed better results at six weeks with a slightly but statistically significant improvement at 12 weeks with Visual Analogue Scale scores of 2.40 (0.26) ( P < 0.001). Pilates intervention in patients with chronic non-specific low back pain is effective in the management of disability, pain and kinesiophobia.

The aim of this study was to investigate the effect of active group-exercising on women with non specific chronic low back pain (NSCLBP) in a sitting position. 25 females with NSCLBP underwent 8 group sitting-exercise sessions of a 45 minute duration, over an 8 week period. Pain intensity (VAS), back specific disability (Rolland Morris questionnaire-RMQ), and lumbar flexion and extension ranges of motion were measured twice, for reliability tests and cut-off score values, with a 1 week interval between measurements, prior to intervention and subsequently, six weeks following intervention. Several significant changes in outcome measures were indicated following intervention compared with baseline (p < 0.001): an increase in lumbar flexion and extension (mean differences of 6° for flexion and 4° for extension, cutoff score = 5.91°); reduction in VAS score (mean difference=4.21, cutoff score =4.48); an increase in RMQ total score (mean difference=10.76, cutoff score=8.15). Changes in the VAS score was highly correlated with changes in the RMQ score (r=- 6.35). A functional program of group-exercising conducted in a sitting position, improved the functional, painful status and lumbar ranges of motion in the sagittal plane of women suffering from non specific chronic low back pain. As sitting is considered the most common posture in today's workplace, applying this protocol during working hours would be very effective.

Neurocardiology: Therapeutic Implications for Cardiovascular Disease

PubMed Central

Goldstein, David S.

2016-01-01

SUMMARY The term “neurocardiology” refers to physiologic and pathophysiological interplays of the nervous and cardiovascular systems. This selective review provides an update about cardiovascular therapeutic implications of neurocardiology, with emphasis on disorders involving primary or secondary abnormalities of catecholamine systems. Concepts of scientific integrative medicine help understand these disorders. Scientific integrative medicine is not a treatment method or discipline but a way of thinking that applies systems concepts to acute and chronic disorders of regulation. Some of these concepts include stability by negative feedback regulation, multiple effectors, effector sharing, instability by positive feedback loops, allostasis, and allostatic load. Scientific integrative medicine builds on systems biology but is also distinct in several ways. A large variety of drugs and non-drug treatments are now available or under study for neurocardiologic disorders in which catecholamine systems are hyperfunctional or hypofunctional. The future of therapeutics in neurocardiology is not so much in new curative drugs as in applying scientific integrative medical ideas that take into account concurrent chronic degenerative disorders and interactions of multiple drug and non-drug treatments with each other and with those disorders.

Dynamic multi-segmental postural control in patients with chronic non-specific low back pain compared to pain-free controls: A cross-sectional study.

PubMed

Reduced postural control is thought to contribute to the development and persistence of chronic non-specific low back pain (CNLBP). It is therefore frequently assessed in affected patients and commonly reported as the average amount of postural sway while standing upright under a variety of sensory conditions. These averaged linear outcomes, such as mean centre of pressure (CP) displacement or mean CP surface areas, may not reflect the true postural status. Adding nonlinear outcomes and multi-segmental kinematic analysis has been reported to better reflect the complexity of postural control and may detect subtler postural differences. In this cross-sectional study, a combination of linear and nonlinear postural parameters were assessed in patients with CNLBP (n = 24, 24-75 years, 9 females) and compared to symptom-free controls (CG, n = 34, 22-67 years, 11 females). Primary outcome was postural control measured by variance of joint configurations (uncontrolled manifold index, UI), confidence ellipse surface areas (CEA) and approximate entropy (ApEn) of CP dispersion during the response phase of a perturbed postural control task on a swaying platform. Secondary outcomes were segment excursions and clinical outcome correlates for pain and function. Non-parametric tests for group comparison with P-adjustment for multiple comparisons were conducted. Principal component analysis was applied to identify patterns of segmental contribution in both groups. CNLBP and CG performed similarly with respect to the primary outcomes. Comparison of joint kinematics revealed significant differences of hip (P < .001) and neck (P < .025) angular excursion, representing medium to large group effects (r's = .36 - .51). Significant (P's < .05), but moderate correlations of ApEn (r = -.42) and UI (r = -.46) with the health-related outcomes were observed. These findings lend further support to the notion that averaged linear outcomes do not suffice to describe subtle postural differences in CNLBP patients with low to moderate pain status.

most people in contemporary western society die of the chronic diseases of old age. Whilst palliative care is appropriate for elderly patients with chronic, non-malignant disease, few of these patients access such care compared with cancer patients. Objective referral criteria based on accurate estimation of survival may facilitate more timely referral of non-cancer patients most appropriate for specialist palliative care. to identify tools and predictor variables that might aid clinicians estimate survival and assess palliative status in non-cancer patients aged 65 years and older. systematic review and quality assessment using criteria modified from the literature. 11 studies that evaluated prognoses in hospitalised and community-based older adults with non-malignant disease were identified. Key generic predictors of survival were increased dependency of activities of daily living, presence of comorbidities, poor nutritional status and weight loss, and abnormal vital signs and laboratory values. Disease-specific predictors of survival were identified for dementia, chronic obstructive pulmonary disorder and congestive heart failure. No study evaluated the relationship between survival and palliative status. prognostic models that attempt to estimate survival of < or = 6 months in non-cancer patients have generally poor discrimination, reflecting the unpredictable nature of most non-malignant disease. However, a number of generic and disease-specific predictor variables were identified that may help clinicians identify older, non-cancer patients with poor prognoses and palliative care needs. Simple, well-validated prognostic models that provide clinicians with objective measures of palliative status in non-cancer patients are needed. Additionally, research that evaluates the effect of general and specialist palliative care on psychosocial outcomes in non-cancer patients and their carers is needed.

Cause for concern in the use of non-steroidal anti-inflammatory medications in the community -a population-based study

PubMed Central

2011-01-01

Background Non-steroidal anti-inflammatory (NSAID) medications are a common cause of reported adverse drug side-effects. This study describes the prevalence of non-steroidal anti-inflammatory (NSAID) use (other than low-dose aspirin) and the presence of co-existing relative contraindications to NSAID use and chronic conditions in a representative population sample. Methods Data were analysed from 3,206 adults attending first follow-up of the North West Adelaide Health Study (NWAHS) in 2004 - 2006, a longitudinal representative population study. Medications were brought into study clinic visits by participants. Clinical assessment included measured blood pressure, kidney function, serum cholesterol, blood glucose. Questionnaires assessed demographics, lifestyle risk factors, physician-diagnosed chronic conditions. Data were weighted to census measures by region, age group, gender, and probability of selection in the household, to provide population representative estimates. Pearson's Chi-square tests determined significant differences in proportions. Multiple logistic regression was used to examine associations of socio-demographic characteristics with use of NSAIDs. Results Of 3,175 participants, 357 (11.2%), and 16% of those aged > 55 years, reported using either non-specific NSAIDs or COX-2 inhibitors, other than low-dose aspirin. Among people using NSAIDs, 60.8% had hypertension, 30.8% had Stage 3 or higher chronic kidney disease, 17.2% had a history of cardiovascular disease (CVD) and 20.7% had a > 15% 10-year CVD risk. The prevalence of NSAID use among people with hypertension was 16%, with kidney disease 15.9%, and a history of CVD 20.0%. Among people taking diuretics, 24.1% were also taking NSAIDs, and of those taking medications for gastro-esophageal reflux, 24.7% were on NSAIDs. Prescription-only COX-2 inhibitors, but not other NSAIDs, were used more by people > 75 years than by 35-54 year olds (OR 3.7, 95% CI 2.0, 6.7), and also were more commonly used by people with hypertension, cardiac and kidney disease. Conclusions There is a high prevalence of current NSAID use among groups at-risk for significant drug-related adverse events or who have major chronic conditions that are relative contraindications to NSAID use. Assessment of absolute risks regarding cardiovascular and kidney disease need to take into account use of medications such as NSAIDs. The potential to make a substantial impact on chronic disease burden via improved use of NSAIDs is considerable. PMID:21733195

Medication-taking behaviours in chronic kidney disease with multiple chronic conditions: a meta-ethnographic synthesis of qualitative studies.

PubMed

Bartlett Ellis, Rebecca J; Welch, Janet L

2017-03-01

To identify behaviours associated with taking medications and medication adherence reported in qualitative studies of adults with chronic kidney disease and coexisting multiple chronic conditions. To inform medication adherence interventions, information is needed to clarify the nature of the relationships between behaviours that support medication-taking and medication adherence in multiple chronic conditions. Meta-ethnographic review and synthesis. CINAHL Complete, MEDLINE and PsycINFO databases were searched. Five qualitative studies met the inclusion criteria. A meta-ethnographic approach was used for synthesis. Medication-taking behaviours were abstracted from study findings and synthesised according to the contexts in which they occur and interpreted within a new developing framework named the Medication-taking Across the Care Continuum and Adherence-related Outcomes. Twenty categories of medication-taking behaviours occurred in three main contexts: (1) patient-provider clinical encounters, (2) pharmacy encounters and (3) day-to-day management. These behaviours are distinctly different, multilevel and interrelated. Together they represent a process occurring across a continuum. Future medication adherence research should consider using a multilevel ecological view of medication management. Clinical practice and policy development can benefit from further understanding socio-contextual behaviours that occur across the continuum. Nurses should have greater presence in chronic disease management and be positioned to support the day-to-day home management of patients' medications. Healthcare professionals can partner with patients to elucidate how these behaviours are enacted across the care continuum and in day-to-day management to identify opportunities to intervene on specific behaviours and promote medication adherence. © 2016 John Wiley & Sons Ltd.

[Chronic renal disease as cardiovascular risk factor].

PubMed

Hermans, M M H; Kooman, J P; Stehouwer, C D A

2008-07-19

A lowering of the glomerular filtration rate (GFR) and/or the presence of albuminuria are signs of chronic renal disease. Both variables are for the most part independently associated with an increased risk of cardiovascular morbidity and mortality. Albuminuria is a marker of endothelial dysfunction. A decrease of the GFR is associated with non-traditional risk factors, e.g. renal anaemia, uraemic toxins due to a decrease of the renal clearance, hyperhomocysteinaemia caused by a diminished homocysteine metabolism, excessive activation of the sympathetic nervous system which is related to sleep apnoea syndrome, oxidative stress and dyslipidaemia associated with the formation of vasotoxic, oxidised LDL cholesterol. These non-traditional risk factors may, alone or in combination with traditional atherogenic risk factors (e.g. age, male gender, smoking, hypercholesterolaemia, hypertension, obesity, positive family history and diabetes mellitus), partially via endothelial dysfunction, result in harmful effects on arterial function, increasing cardiovascular morbidity and mortality. Different stages of chronic kidney disease are associated with specific risk factors, making a specific therapeutic approach essential.

Prolonged striatal disinhibition as a chronic animal model of tic disorders.

PubMed

Vinner, Esther; Israelashvili, Michal; Bar-Gad, Izhar

2017-12-01

Experimental findings and theoretical models have associated Tourette syndrome with abnormal striatal inhibition. The expression of tics, the hallmark symptom of this disorder, has been transiently induced in non-human primates and rodents by the injection of GABA A antagonists into the striatum, leading to temporary disinhibition. The novel chronic model of tic expression utilizes mini-osmotic pumps implanted subcutaneously in the rat's back for prolonged infusion of bicuculline into the dorsolateral striatum. Tics were expressed on the contralateral side to the infusion over a period of multiple days. Tic expression was stable, and maintained similar properties throughout the infusion period. Electrophysiological recordings revealed the existence of tic-related local field potential spikes and individual neuron activity changes that remained stable throughout the infusion period. The striatal disinhibition model provides a unique combination of face validity (tic expression) and construct validity (abnormal striatal inhibition) but is limited to sub-hour periods. The new chronic model extends the period of tic expression to multiple days and thus enables the study of tic dynamics and the effects of behavior and pharmacological agents on tic expression. The chronic model provides similar behavioral and neuronal correlates of tics as the acute striatal disinhibition model but over prolonged periods of time, thus providing a unique, basal ganglia initiated model of tic expression. Chronic expression of symptoms is the key to studying the time varying properties of Tourette syndrome and the effects of multiple internal and external factors on this disorder.

Diet components can suppress inflammation and reduce cancer risk.

PubMed

Hardman, W Elaine

2014-06-01

Epidemiology studies indicate that diet or specific dietary components can reduce the risk for cancer, cardiovascular disease and diabetes. An underlying cause of these diseases is chronic inflammation. Dietary components that are beneficial against disease seem to have multiple mechanisms of action and many also have a common mechanism of reducing inflammation, often via the NFκB pathway. Thus, a plant based diet can contain many components that reduce inflammation and can reduce the risk for developing all three of these chronic diseases. We summarize dietary components that have been shown to reduce cancer risk and two studies that show that dietary walnut can reduce cancer growth and development. Part of the mechanism for the anticancer benefit of walnut was by suppressing the activation of NFκB. In this brief review, we focus on reduction of cancer risk by dietary components and the relationship to suppression of inflammation. However, it should be remembered that most dietary components have multiple beneficial mechanisms of action that can be additive and that suppression of chronic inflammation should reduce the risk for all three chronic diseases.

1976-03-01

Administration of a single acute dose (20 mg/kg body weight) of methadone hydrochloride to both male and female mice increased the specific activity of NADPH-cytochrome c reductase and did not change much the content of cytochrome P-450 of their liver microsomes. Administration of multiple acute doses of methadone in male mice increased the specific activity of cytochrome c reductase and the content of cytochrome P-450 of their liver microsomes. Chronic administration of progressively increasing doses of methadone (up to 40 mg/kg body weight) to male mice increased the specific activity of c reductase. Similar chronic administration of methadone up to 28 mg/kg body weight also increased the microsomal content of P-450, but with higher doses of methadone, the content of P-450 declined and finally dropped slightly below control levels. The levels of c reductase activity and P-450 content returned to normal about two weeks after discontinuation of methadone administration.

Evaluation of the assessment and documentation of chronic wounds in residential social care in the Czech Republic.

Accurate evaluation of non-healing, chronic wounds followed by the selection of an appropriate therapeutic strategy is a must for the foundation of health-care management. Assessment of non-healing chronic wounds in clinical practice in the Czech Republic is not standardised in acute care settings or in residential social care facilities. The aim of the study was to analyse the methods being used to assess non-healing, chronic wounds in residential social services in the Czech Republic, where more patients with chronic wounds are present because of the increasing incidence of wounds in old age. The research was carried out at 66 residential social care institutions across all regions of the Czech Republic. A mixed model was used for the research (participatory observation including creation of field notes and content analysis of documents for documentation and analysis of qualitative and quantitative data). The same methodology was used in previous work which has been done in acute care settings in 2013. The results of this research have corroborated the inconsistencies in procedures used by general nurses for assessment of non-healing, chronic wounds. However, the situation was found to be more positive with regard to the evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of the wound) compared with the evaluation of more specific parameters (e.g. exudate or signs of infection). This included not only the number of observed variables, but also the action taken. Both were improved when a consultant for wound healing was present. An effective strategy for wound management depends on the method and scope of the assessment of non-healing, chronic wounds in place in clinical practice in observed facilities; improvement may be expected following the general introduction of 'non-healing, chronic wound assessment' algorithm.

There is a paucity of research exploring how spouses to older adults with multiple chronic conditions make meaning of their caregiving experience. For this study, we asked: What is the experience of spousal caregivers to persons with multiple chronic conditions? We applied Thorne's interpretive description approach, interviewing 18 spouses who provided a rich description of their caregiving experience; interviews were transcribed verbatim and thematically analysed. Themes were categorized according to challenges encountered, rewards gleaned, and sustaining strategies employed by participants in caregiving to their spouse with multiple chronic conditions. Unique findings relate to the challenges inherent in decision-making within the context of multiple chronic conditions. This article begins to address the gap in the literature regarding the caregiving experience within the context of multiple chronic conditions.

Objective To assess the association between multiple pharmacy use and medication adherence and potential drug-drug interactions (DDIs) among older adults. Design, Setting, and Participants Cross-sectional propensity score-weighted analysis of 2009 claims data from a nationally representative sample of 926,956 Medicare Part D beneficiaries aged >65 continuously enrolled in fee-for-service Medicare and Part D that year, and filled >1 prescription at a community/retail or mail order pharmacy. Multiple pharmacy use was defined as concurrent (overlapping time periods) or sequential use (non-overlapping time periods) of >2 pharmacies in the year. Measurements Medication adherence was calculated using a proportion of days covered ≥0.80 for eight therapeutic categories (β-blockers, renin angiotensin system antagonists, calcium channel blockers, statins, sulfonylureas, biguanides [i.e., metformin], thiazolidinediones, and dipeptidyl peptidase-IV inhibitors). Potential DDIs arising from use of certain drugs across a broad set of classes were defined as the concurrent filling of two interacting drugs. Results Overall, 38.1% of the sample used multiple pharmacies. Those using multiple pharmacies (both concurrently and sequentially) consistently had higher adjusted odds of non-adherence (ranging from 1.10 to 1.31, p<0.001) across all chronic medication classes assessed after controlling for socio-demographic, health status and access to care factors, compared to single pharmacy users. The adjusted predicted probability of exposure to a DDI was also slightly higher for those using multiple pharmacies concurrently (3.6%) compared to single pharmacy users (3.2%, AOR 1.11, 95% CI 1.08–1.15) but lower in individuals using multiple pharmacies sequentially (2.8%, AOR 0.85, 95% CI 0.81–0.91). Conclusions Filling prescriptions at multiple pharmacies was associated with lower medication adherence across multiple chronic medications, and a small but statistically significant increase in DDIs among concurrent pharmacy users.

Despite the progressive increase in life expectancy and the relationship between aging with multi-morbidities and the increased use of healthcare resources, current clinical practice guidelines (CPG) on cardiometabolic risk cannot be adequately applied to elderly subjects with multiple chronic conditions. Its management frequently becomes complicated by both, an excessive use of medications that may lead to overtreatment, drug interactions and increased toxicity, and errors in dosage and non-compliance. Concerned by this gap, the Spanish Society of Internal Medicine created a group of independent experts on cardiometabolic risk who discussed what they considered to be unanswered questions in the management of elderly patients. Current guidelines do not specifically address the problem of elderly with multiple chronic conditions. For this reason, the combined use of the limited available evidence, clinical experience and common sense, could all help us to address this unmet need. In very old people, life expectancy and functionality are the most important factors for guiding potential treatments. Their higher propensity to develop serious adverse events and their shorter lifespan could prevent them from obtaining the potential benefits of the interventions administered. In this document, experts on cardiometabolic risk factors have established a number of consensual recommendations that have taken into account international guidelines and clinical experience, and have also considered the more effective use of healthcare resources. This document is intended to provide general recommendations for clinicians and to promote the effective use of procedures and medications.

Sporadic ganglioneuromatosis of esophagogastric junction in a patient with gastro-esophageal reflux disorder and intestinal metaplasia.

A 58-year-old female with a recurrent history of upper abdominal pain and intermittent dysphagia underwent endoscopic evaluation that demonstrated an irregular and nodular esophago-gastric (EG) junction and grade I erosive esophagitis. Biopsies showed prominent intestinal metaplasia of Barrett's type without dysplasia, chronic inflammation and multiple aggregates of large cells within the mucosal lamina propria, some with spindle shaped nuclei. Immunohistochemistry stains for keratins AE-1/AE-3 were negative, while S-100 and NSE were positive. This, together with routine stains, was diagnostic for mucosal ganglioneuromatosis. The background of chronic inflammation with intestinal type metaplasia was consistent with long-term reflux esophagitis. No evidence of achalasia was seen. Biopsies of gastric antrum and fundus were unremarkable, without ganglioneural proliferation. Colonoscopy was unremarkable. No genetic syndromes were identified in the patient including familial adenomatous polyposis and multiple endocrine neoplasia type IIb (MEN IIb). Iansoprazole (Prevacid) was started by oral administration each day with partial relief of symptoms. Subsequent esophagogastroscopy repeated at 4 mo showed normal appearing EG junction. Esophageal manometry revealed a mild non-specific lower esophageal motility disorder. Mild motor dysfunction is seen with gastro-esophageal reflux disease (GERD) and we feel that the demonstration of localized ganglioneuromatosis was not likely related etiologically. In the absence of findings that might suggest neural hypertrophy, such as achalasia, the nodular mucosal irregularity seen with this instance of ganglioneuromatosis may, however, have exacerbated the patient's reflux.

The role of gut microbiome and associated metabolome in the regulation of neuroinflammation in multiple sclerosis and its implications in attenuating chronic inflammation in other inflammatory and autoimmune disorders.

The importance of the gut microbiome in the regulation of non-infectious diseases has earned unprecedented interest from biomedical researchers. Widespread use of next-generation sequencing techniques has prepared a foundation for further research by correlating the presence of specific bacterial species with the onset or severity of a disease state, heralding paradigm-shifting results. This review covers the mechanisms through which a dysbiotic gut microbiota contributes to the pathological symptoms in an autoimmune neurodegenerative disorder, multiple sclerosis (MS). Although the central nervous system (CNS) is protected by the blood-brain barrier (BBB), it is unclear how gut dysbiosis can trigger potential immunological changes in the CNS in the presence of the BBB. This review focuses on the immunoregulatory functionality of microbial metabolites, which can cross the BBB and mediate their effects directly on immune cells within the CNS and/or indirectly through modulating the response of peripheral T cells to stimulate or inhibit pro-inflammatory chemokines and cytokines, which in turn regulate the autoimmune response in the CNS. Although more research is clearly needed to directly link the changes in gut microbiome with neuroinflammation, focusing research on microbiota that produce beneficial metabolites with the ability to attenuate chronic inflammation systemically as well as in the CNS, can offer novel preventive and therapeutic modalities against a wide array of inflammatory and autoimmune diseases. © 2018 John Wiley & Sons Ltd.

Sleep problems are common in patients with chronic obstructive pulmonary disease (COPD), but the validity of patient-reported outcome measures (PROMs) that measure sleep dysfunction has not been evaluated. We have reviewed the literature to identify disease-specific and non-disease-specific sleep PROMs that have been validated for use in COPD patients. The review also examined the psychometric properties of identified sleep outcome measures and extracted point and variability estimates of sleep instruments used in COPD studies. The online EMBASE, MEDLINE, PsycINFO, and SCOPUS databases for all years to May 2014 were used to source articles for the review. The review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Criteria from the Medical Outcomes Trust Scientific Advisory Committee guidelines were used to evaluate the psychometric properties of all sleep PROMs identified. One COPD-specific and six non-COPD-specific sleep outcome measures were identified and 44 papers met the review selection criteria. We only identified one instrument, the COPD and Asthma Sleep Impact Scale, which was developed specifically for use in COPD populations. Ninety percent of the identified studies used one of two non-disease-specific sleep scales, ie, the Pittsburgh Sleep Quality Index and/or the Epworth Sleep Scale, although neither has been tested for reliability or validity in people with COPD. The results highlight a need for existing non-disease-specific instruments to be validated in COPD populations and also a need for new disease-specific measures to assess the impact of sleep problems in COPD.

However, the situation was found to be more positive with regard to evaluation of basic/fundamental parameters of a wound (e.g. size, depth and location of a wound) compared with the evaluation of more specific parameters (e.g. exudate or signs of infection). This included not only the number of observed variables, but also the action taken. Both were significantly improved when a consultant for wound healing was present (P = 0·047). The same applied to facilities possessing a certificate of quality issued by the Czech Wound Management Association (P = 0·010). In conclusion, an effective strategy for wound management depends on the method and scope of the assessment of non-healing, chronic wounds in place in clinical practice in observed facilities; improvement may be expected following the general introduction of a 'non-healing, chronic wound assessment' algorithm. © 2014 The Authors.

Immunologic Endocrine Disorders

Autoimmunity affects multiple glands in the endocrine system. Animal models and human studies highlight the importance of alleles in HLA (human leukocyte antigen)-like molecules determining tissue specific targeting that with the loss of tolerance leads to organ specific autoimmunity. Disorders such as type 1A diabetes, Grave's disease, Hashimoto's thyroiditis, Addison's disease, and many others result from autoimmune mediated tissue destruction. Each of these disorders can be divided into stages beginning with genetic susceptibility, environmental triggers, active autoimmunity, and finally metabolic derangements with overt symptoms of disease. With an increased understanding of the immunogenetics and immunopathogenesis of endocrine autoimmune disorders, immunotherapies are becoming prevalent, especially in type 1A diabetes. Immunotherapies are being used more in multiple subspecialty fields to halt disease progression. While therapies for autoimmune disorders stop the progress of an immune response, immunomodulatory therapies for cancer and chronic infections can also provoke an unwanted immune response. As a result, there are now iatrogenic autoimmune disorders arising from the treatment of chronic viral infections and malignancies. PMID:20176260

Impact of chronic cough on quality of life.

French, C L; Irwin, R S; Curley, F J; Krikorian, C J

Cough is the most common complaint for which adult patients seek medical care in the United States; however, the reason(s) for this is unknown. To determine whether chronic cough was associated with adverse psychosocial or physical effects on the quality of life and whether the elimination of chronic cough with specific therapy improved these adverse effects. The study design was a prospective before-and-after intervention trial with patients serving as their own controls. Study subjects were a convenience sample of 39 consecutive and unselected adult patients referred for evaluation and management of a chronic, persistently troublesome cough. Baseline data were available for 39 patients and follow-up for 28 patients (22 women and 6 men). At baseline, demographic, Adverse Cough Outcome Survey (ACOS), and Sickness Impact Profile (SIP) data were collected and patients were managed according to a validated, systematic protocol. Following specific therapy for cough, ACOS and SIP instruments were readministered. The ages, sex, duration, and spectra and frequencies of the causes of cough were similar to multiple other studies. At baseline, patients reported a mean +/- SD of 8.6 +/- 4.8 types of adverse occurrences related to cough. There were significant correlations between multiple ACOS items and total, physical, and psychosocial SIP scores. Psychosocial score correlated with total number of symptoms (P<.02). After cough disappeared with treatment, ACOS complaints decreased to a mean +/- SD of 1.9 +/- 3.2 (P<.0001) as did total (mean +/- SD, 4.8 +/- 4.5 to 1.8 +/- 2.2) (P= .004), psychosocial (mean +/- SD, 4.2 +/- 6.8 to 0.8 +/- 2.3) (P = .004), and physical (mean +/- SD, 2.2 +/- 2.9 to 0.9 +/- 1.8) (P = .05) SIP scores. Multiple linear regression analysis showed that 54% of variability of the psychosocial SIP score was explained by 4 ACOS items while none of the physical score was explained. Chronic cough was associated with deterioration in patients' quality of life. The health-related dysfunction was most likely psychosocial. The ACOS and SIP appear to be valid tools in assessing the impact of chronic cough.

Chronic pancreatitis: A diagnostic dilemma

Typical clinical symptoms of chronic pancreatitis are vague and non-specific and therefore diagnostic tests are required, none of which provide absolute diagnostic certainly, especially in the early stages of disease. Recently-published guidelines bring much needed structure to the diagnostic work-up of patients with suspected chronic pancreatitis. In addition, novel diagnostic modalities bring promise for the future. The assessment and diagnosis of pancreatic exocrine insufficiency remains challenging and this review contests the accepted perspective that steatorrhea only occurs with > 90% destruction of the gland.

Incidence of all types of lymphatic and hematopoietic cancers, including Hodgkin’s lymphoma, non-Hodgkin's lymphoma, multiple myeloma, acute and chronic myeloid leukemia (AML and CML respectively), chronic lymphocytic leukemia (CLL) and other forms of leukemia have been studied in a cohort of 22,373 workers employed at the Mayak Production Association (PA) main facilities during 536,126 person-years of follow-up from the start of employment between 1948 and 1982 to the end of 2004. Risk assessment was performed for both external gamma-radiation and internal alpha-exposure of red bone marrow due to incorporated Pu-239 using Mayak Workers Dosimetry System 2008 taking into account non-radiation factors. The incidence of leukemia excluding CLL showed a non-linear dose response relationship for external gamma exposure with exponential effect modifiers based on time since exposure and age at exposure. Among the major subtypes of leukemia, the excess risk of AML was the highest within the first 2–5 years of external exposure (ERR per Gy: 38.40; 90% CI: 13.92–121.4) and decreased substantially thereafter, but the risks remained statistically significant (ERR per Gy: 2.63; 90% CI: 0.07–12.55). In comparison, excess CML first occurred 5 years after exposure and decreased about 10 years after exposure, although the association was not statistically significant (ERR per Gy: 1.39; 90% CI: -0.22–7.32). The study found no evidence of an association between leukemia and occupational exposure to internal plutonium ERR per Gy 2.13; 90% CI: <0–9.45). There was also no indication of any relationship with either external gamma or internal plutonium radiation exposure for either incidence of Hodgkin or non-Hodgkin lymphoma or multiple myeloma.

Multiple sclerosis (MS) is a chronic inflammatory disease that involves central nervous system, and is generally associated with demyelination and axonal lesion. The effective factors for initiation of the inflammatory responses have not been known precisely so far. Leukotrienes (LTs) are inflammatory mediators with increased levels in the cerebrospinal fluid of MS patients and in experimental models of multiple sclerosis. Inhibition of LT receptors with specific antagonists can decrease inflammatory responses. In this review article we try to clarify the role of LT receptor antagonists and also inhibitors of enzymes which are involved in LTs generating pathway for treating multiple sclerosis as new targets for MS therapy. Moreover, we suggest that blockage of LT receptors by potent specific antagonists and/or agonists can be as a novel useful method in treatment of MS.

Clonal B cells in Waldenström's macroglobulinemia exhibit functional features of chronic active B-cell receptor signaling

Waldenström's macroglobulinemia (WM) is a B-cell non-Hodgkin's lymphoma (B-NHL) characterized by immunoglobulin M (IgM) monoclonal gammopathy and the medullary expansion of clonal lymphoplasmacytic cells. Neoplastic transformation has been partially attributed to hyperactive MYD88 signaling, secondary to the MYD88 L265P mutation, occurring in the majority of WM patients. Nevertheless, the presence of chronic active B-cell receptor (BCR) signaling, a feature of multiple IgM+ B-NHL, remains a subject of speculation in WM. Here, we interrogated the BCR signaling capacity of primary WM cells by utilizing multiparametric phosphoflow cytometry and found heightened basal phosphorylation of BCR-related signaling proteins, and augmented phosphoresponses on surface IgM (sIgM) crosslinking, compared with normal B cells. In support of those findings we observed high sIgM expression and loss of phosphatase activity in WM cells, which could both lead to signaling potentiation in clonal cells. Finally, led by the high-signaling heterogeneity among WM samples, we generated patient-specific phosphosignatures, which subclassified patients into a ‘high' and a ‘healthy-like' signaling group, with the second corresponding to patients with a more indolent clinical phenotype. These findings support the presence of chronic active BCR signaling in WM while providing a link between differential BCR signaling utilization and distinct clinical WM subgroups. PMID:26867669

The physiological roles of phytosterols in chronic inflammation, which are believed to be involved in the underlying mechanisms for metabolic diseases, have yet to be elucidated. Therefore, in the present study, we aimed to elucidate the physiological roles of phytosterols in both clinical studies and animal experiments. We observed the existence of rather specific negative correlations between the serum sitosterol level and the serum IL-6 and the TNF-α levels in both diabetic subjects (n=46) and non-diabetic subjects (n=178). Multiple regression analyses also revealed that the serum IL-6 and TNF-α levels exhibited strong negative correlations with the serum sitosterol levels. When ABCG5/8 KO mice with markedly elevated plasma sitosterol levels and ABCG5/8 hetero mice were fed a high-fat diet, we observed that the increase in body weight, the fatty liver changes, and the expansion of perigonadal adipose tissues were suppressed in ABCG5/8 KO mice without any modulation of food intake. We also observed that the plasma IL-6 and TNF-α levels, the expressions of TNF-α and PAI-1 in the liver and the expressions of the IL-6, TNF-α, and MCP-1 levels in the adipose tissue were lower in ABCG5/8 KO mice. These results suggest that sitosterol might suppress obesity-related chronic inflammation and might be applicable to the treatment of metabolic diseases. Copyright © 2017 Elsevier B.V.

To examine multiple chronic conditions and related health care expenditures in children. Retrospective cohort study of all dependents of Mayo Clinic employees aged 0-17 on Jan 1, 2004 with continuous health benefits coverage for 4 years (N=14,727). Chronic conditions, health care utilization, and associated expenditures were obtained from medical and pharmacy claims. The most prevalent chronic conditions were asthma/chronic obstructive pulmonary disease (12%), allergic rhinitis (11%), and behavior problems (9%). The most costly conditions were congenital anomalies, asthma/chronic obstructive pulmonary disease, and behavior problems ($9602, $4335, and $5378 annual cost per child, respectively). Annual health care expenditures increased substantially with the number of chronic conditions, and a small proportion of children with multiple chronic conditions accounted for a large proportion of health care costs. In addition, those with multiple chronic conditions were more likely to persist in the top 10th percentile spender group in year-to-year spending. Children with multiple chronic conditions accounted for a large proportion of health care expenditures. These children were also likely to persist as high spenders in the 4-year time frame. Further research into effective ways to manage the health care delivery for children with multiple chronic conditions is needed. © The Author(s) 2014.

ANA testing in the presence of acute and chronic infections.

PubMed

Litwin, Christine M; Binder, Steven R

2016-01-01

Autoantibody testing is performed to help diagnose patients who have clinical symptoms suggestive of possible autoimmune diseases. Antinuclear antibodies (ANA) are present in many systemic autoimmune conditions such as systemic lupus erythematosus (SLE). However, a positive ANA test may also be seen with non-autoimmune inflammatory diseases, including both acute and chronic infections. When the ANA test is used as an initial screen in patients with non-specific clinical symptoms, such as fever, joint pain, myalgias, fatigue, rash, or anemia, the likelihood of a positive result due to infection will increase, especially in children. This article identifies acute and chronic infectious diseases that are likely to produce a positive ANA result and summarizes recent literature addressing both the causes and consequences of these findings.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction due to a fungus, Aspergillus fumigatus. It is typically seen in patients with long-standing asthma. Our patient was a non-asthmatic 18 years old male who presented with chronic cough for 2 years. Peripheral blood eosinophilia and elevated scrum IgE were observed. His x-ray chest revealed v-shaped opacity in the left upper lobe close to the hilum. High resolution computed tomographic scan of the chest revealed multiple dilated bronchi filled with mucous (bronchoceles) and central bronchiectasis (CB) involving main segmental bronchi. Central bronchiectasis (CB) was typical of ABPA but bronchocele formation was a rare manifestation of the disease. The patient was managed with oral prednisolone and was relieved of his symptoms. Occurrence of ABPA in non-asthmatics is very rare and deserves reporting.

Why do people with chronic disease not contact consumer health organisations? A survey of general practice patients.

Aim Consumer health organisations (CHOs) are non-profit or voluntary sector organisations that promote and represent the interests of patients and carers affected by particular conditions. The purpose of this study was to examine, among patients with chronic disease, what differentiates those who contact CHOs from those who do not and what stops people from making contact. CHOs can enhance people's capacity to manage chronic disease by providing information, education and psychosocial support, but are under-utilised. Little is known about barriers to access. Data were from a baseline telephone survey conducted as part of a randomised trial of an intervention to improve access to CHOs. Participants constituted a consecutive sample of 276 adults with diagnosed chronic disease recruited via 18 general practitioners in Brisbane, Australia. Quantitative survey items examined participants' use and perceptions of CHOs and a single open-ended question explored barriers to CHO use. Multiple logistic regression and thematic analysis were used. Findings Overall, 39% of participants had ever contacted a CHO for their health and 28% had contacted a CHO specifically focussed on their diagnosed chronic condition. Diabetes, poorer self-reported physical health and greater health system contact were significantly associated with CHO contact. The view that 'my doctor does it all' was prevalent and, together with a belief that their health problems were 'not serious enough', was the primary reason patients did not make contact. Attitudinal and system-related barriers limit use of CHOs by those for whom they are designed. Developing referral pathways to CHOs and promoting awareness about what they offer is needed to improve access.

Association of interleukin-1 gene variations with moderate to severe chronic periodontitis in multiple ethnicities

Background and Objective Genetic markers associated with disease are often non-functional and generally tag one or more functional “causative” variants in linkage disequilibrium. Markers may not show tight linkage to the causative variants across multiple ethnicities due to evolutionary divergence, and therefore may not be informative across different population groups. Validated markers of disease suggest causative variants exist in the gene and, if the causative variants can be identified, it is reasonable to hypothesize that such variants will be informative across diverse populations. The aim of this study was to test that hypothesis using functional Interleukin-1 (IL-1) gene variations across multiple ethnic populations to replace the non-functional markers originally associated with chronic adult periodontitis in Caucasians. Material and Methods Adult chronic periodontitis cases and controls from four ethnic groups (Caucasians, African Americans, Hispanics and Asians) were recruited in the USA, Chile and China. Genotypes of IL1B gene single nucleotide polymorphisms (SNPs), including three functional SNPs (rs16944, rs1143623, rs4848306) in the promoter and one intronic SNP (rs1143633), were determined using a single base extension method or TaqMan 5′ nuclease assay. Logistic regression and other statistical analyses were used to examine the association between moderate to severe periodontitis and IL1B gene variations, including SNPs, haplotypes and composite genotypes. Genotype patterns associated with disease in the discovery study were then evaluated in independent validation studies. Results Significant associations were identified in the discovery study, consisting of Caucasians and African Americans, between moderate to severe adult chronic periodontitis and functional variations in the IL1B gene, including a pattern of four IL1B SNPs (OR = 1.87, p < 0.0001). The association between the disease and this IL1B composite genotype pattern was validated in two additional studies consisting of Hispanics (OR = 1.95, p = 0.04) or Asians (OR = 3.27, p = 0.01). A meta-analysis of the three populations supported the association between the IL-1 genotype pattern and moderate to severe periodontitis (OR 1.95; p < 0.001). Our analysis also demonstrated that IL1B gene variations had added value to conventional risk factors in predicting chronic periodontitis. Conclusion This study validated the influence of IL-1 genetic factors on the severity of chronic periodontitis in four different ethnicities. PMID:24690098

Strategies for prevention and management of musculoskeletal conditions. Low back pain (non-specific).

PubMed

Krismer, M; van Tulder, M

2007-02-01

Low back pain (LBP) is defined as pain localised between the 12th rib and the inferior gluteal folds, with or without leg pain. Most cases are non-specific, but in about 10% of cases a specific cause is identified. Red flags are typical signs or symptoms that are frequently associated with specific LBP. Yellow flags are prognostic factors associated with a more unfavourable and often chronic disabling course of the disease. LBP has a lifetime prevalence of 60-85%. At any one time, about 15% of adults have LBP. LBP poses an economic burden to society, mainly in terms of the large number of work days lost (indirect costs) and less so by direct treatment costs. A substantial proportion of individuals with chronic LBP has been found to have chronic widespread pain. LBP is often associated with other pain manifestations such as headache, abdominal pain and pain in different locations of the extremities. Widespread pain is associated with a worse prognosis compared to localised LBP. Treatment targets are reduction of pain and better activity/participation, including prevention of disability as well as maintainance of work capacity. The evidence from selected and appraised guidelines, systematic reviews and major clinical studies was classified into four levels, level Ia being the best level with evidence from meta-analysis of randomised controlled trials. Key recommendations (level Ia): fitness programmes and advice to stay active can reduce pain, improve function and can prevent LBP becoming chronic. Simple analgesics, NSAIDs and muscle relaxants can reduce pain and can improve and maintain function. Maintaining physical activity, avoiding rest and manual therapy can reduce pain and maintain and restore function in acute LBP. Behavioural treatment can prevent LBP becoming chronic. Aerobic fitness and endurance training, behavioural treatment and multi-disciplinary treatment programmes can reduce pain and can improve/maintain function in chronic LBP.

Patient eHealth technology offers potential support for disease self-management, but the value of existing applications for patients with multiple chronic conditions (MCCs) is unclear. To understand self-management and health care navigation challenges that patients face due to MCCs and to identify opportunities to support these patients through new and enhanced eHealth technology. After administering a screening survey, we conducted 10 focus groups of 3-8 patients grouped by age, sex, and common chronic conditions. Patients discussed challenges associated with having MCCs and their use of (and desires from) technology to support self-management. Three investigators used standard content analysis methods to code the focus group transcripts. Emergent themes were reviewed with all collaborators, and final themes and representative quotes were validated with a sample of participants. Fifty-three individuals with ≥3 chronic conditions and experience using technology for health-related purposes. Focus group participants had an average of five chronic conditions. Participants reported using technology most frequently to search for health information (96%), communicate with health care providers (92%), track medical information (83%), track medications (77%), and support decision-making about treatment (55%). Three themes emerged to guide eHealth technology development: (1) Patients with MCCs manage a high volume of information, visits, and self-care tasks; (2) they need to coordinate, synthesize, and reconcile health information from multiple providers and about different conditions; (3) their unique position at the hub of multiple health issues requires self-advocacy and expertise. Focus groups identified desirable eHealth resources and tools that reflect these themes. Although patients with multiple health issues use eHealth technology to support self-care for specific conditions, they also desire tools that transcend disease boundaries. By addressing the holistic needs of patients with MCCs, eHealth technology can advance health care from a disease-centered to a patient-centered model.

Central nervous system (CNS) involvement of graft versus host disease (GvHD) is a rare cause of CNS disorders after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Chronic CNS GvHD symptoms are heterogeneous and include cerebrovascular manifestations, demyelinating disease and immune-mediated encephalitis. CNS-Acute GvHD is not formally defined in literature. We report 7 cases of CNS-GvHD among which two had histological-proven disease. We reviewed 32 additional cases of CNS GvHD published in literature since 1990. In this cohort, 34 patients were transplanted for hematologic malignancies, and 5 for non-malignant hematopoiesis disorders. Of these patients, 25 had a history of chronic GvHD and immunosuppressive treatment had been decreased or discontinued in 14 patients before neurological symptoms onset. Median neurological disorder onset was 385 days [7-7320]. Patients had stroke-like episodes (n = 7), lacunar syndromes (n = 3), multiple sclerosis-like presentations (n = 7), acute demyelinating encephalomyelitis-like symptoms (n = 4), encephalitis (n = 14), mass syndrome (n = 1), and 3 had non-specific symptoms. Median neurological symptoms onset was 81.5 days [7-1095] for patients without chronic GVHD history versus 549 days [11-7300] for patients with chronic GVHD (P = 0.001). Patients with early involvement of CNS after allo-HSCT and no chronic GVHD symptoms were more frequently suffering from encephalitis (64% versus 28%, P = 0.07), whereas stroke-like episodes and lacunar symptoms were less frequent (9% versus 36%, P = 0.13). 34 patients with CNS-GvHD were treated with immunosuppressive therapy, including corticosteroids for 31 of them. Other treatments were intravenous immunoglobulin, plasmapheresis, cyclophosphamide, calcineurin inhibitors, mycophenolic acid, methotrexate and etoposide. 27 patients achieved a response: 10 complete responses, 15 partial responses and 2 transient responses. Of 25 patients with sufficient follow-up, 7 were alive and 18 patients deceased after CNS-GvHD diagnosis. CNS-related GvHD is a rare cause of CNS disorders after allo-HSCT and is associated with a poor prognosis.

Performance-related disorders in musicians are most often caused by multiple risk factors. They are based on the chronic complex, rapid and forceful work that requires highest precision, as well as on poor ergonomic conditions and psychological strain. Predominantly, the musculo-skeletal system of the upper extremity and the spine is affected by acute or chronic pain syndromes and neurological disorders. Stage fright and psychological tension frequently generate somatoform disorders and may contribute to the chronification of physical disabilities in musicians. Depending on the individual characteristics, the actual professional activity and the specific instrument, the performance-related risk factors and disorders differ widely. Early and regular prevention clearly contributes to a reduction of medical problems in musicians.

Chronic Nicotine Treatment Impacts the Regulation of Opioid and Non-opioid Peptides in the Rat Dorsal Striatum*

The chronic use of nicotine, the main psychoactive ingredient of tobacco smoking, alters diverse physiological processes and consequently generates physical dependence. To understand the impact of chronic nicotine on neuropeptides, which are potential molecules associated with dependence, we conducted qualitative and quantitative neuropeptidomics on the rat dorsal striatum, an important brain region implicated in the preoccupation/craving phase of drug dependence. We used extensive LC-FT-MS/MS analyses for neuropeptide identification and LC-FT-MS in conjunction with stable isotope addition for relative quantification. The treatment with chronic nicotine for 3 months led to moderate changes in the levels of endogenous dorsal striatum peptides. Five enkephalin opioid peptides were up-regulated, although no change was observed for dynorphin peptides. Specially, nicotine altered levels of nine non-opioid peptides derived from precursors, including somatostatin and cerebellin, which potentially modulate neurotransmitter release and energy metabolism. This broad but selective impact on the multiple peptidergic systems suggests that apart from the opioid peptides, several other peptidergic systems are involved in the preoccupation/craving phase of drug dependence. Our finding permits future evaluation of the neurochemical circuits modulated by chronic nicotine exposure and provides a number of novel molecules that could serve as potential therapeutic targets for treating drug dependence.

Numerous people with chronic conditions like to use traditional Chinese medicine (TCM) treatment, or integrated treatment of TCM and Western medicine (WM). Our study explored the associations between multiple chronic conditions (MCC) and TCM use and the use of specific types of TCM therapy among adults in Taiwan. In addition, we explored the TCM use of adults with seven common types of chronic conditions. In our study, a national representative sample in 2005 was used. The Chronic Condition Indicator and the Clinical Classifications System created by the U.S. Agency for Healthcare Research and Quality were used to define the number of chronic conditions of adults. Logistic regressions adjusted for demographic characteristics were used to analyze the associations. The frequency of TCM use among adults with different numbers of chronic conditions was quantified. TCM use for adults with ≥5 chronic conditions (odds ratio [OR] 1.86) was higher than TCM use for adults with 2-4 chronic conditions (OR 1.51) and TCM use for adults with one chronic condition (OR 1.48). The increase in the OR of the use of Chinese herbs and traumatology manipulative therapy according to the number of chronic conditions was not as substantial as that of acupuncture-moxibustion. The frequency of TCM use exhibited an increasing trend with the increase in the number of chronic conditions (p<.001). Among the seven common types of chronic conditions for adults, TCM use for adults with arthropathy (OR 2.01) was the highest. The probability and frequency of TCM use increased as the number of chronic conditions increased. The probability of Chinese herbs use, traumatology manipulative therapy use, and, particularly, acupuncture-moxibustion use increased as the number of chronic conditions increased. We suggest that government policy makers emphasize administering integrated TCM and WM care to people with chronic conditions or MCC.

Background The Chronic Care Model (CCM) emerged in the 1990s as an approach to re-organize primary care and implement critical elements that enable it to proactively attend to patients with chronic conditions. The chronic care landscape has evolved further, as most patients now present with multiple chronic conditions and increasing psychosocial complexity. These patients face accumulating and overwhelming complexity resulting from the sum of uncoordinated responses to each of their problems. Minimally Disruptive Medicine (MDM) was proposed to respond to this challenge, aiming at improving outcomes that matter to patients with the smallest burden of treatment. We sought to critically appraise the extent to which MDM constructs (e.g., reducing patient work, improving patients’ capacity) have been adopted within CCM implementations. Methods We conducted a systematic review and qualitative thematic synthesis of reports of CCM implementations published from 2011–2016. Results CCM implementations were mostly aligned with the healthcare system’s goals, condition-specific, and targeted disease-specific outcomes or healthcare utilization. No CCM implementation addressed patient work. Few reduced treatment workload without adding additional tasks. Implementations supported patient capacity by offering information, but rarely offered practical resources (e.g., financial assistance, transportation), helped patients reframe their biography with chronic illness, or assisted them in engaging with a supportive social network. Few implementations aimed at improving functional status or quality of life, and only one-third of studies were targeted for patients of low socioeconomic status. Conclusion MDM provides a lens to operationalize how to care for patients with multiple chronic conditions, but its constructs remain mostly absent from how implementations of the CCM are currently reported. Improvements to the primary care of patients with multimorbidity may benefit from the application of MDM, and the current CCM implementations that do apply MDM constructs should be considered exemplars for future implementation work.

To evaluate the effectiveness of transcranial direct current stimulation alone and in combination with cognitive behavioural management in patients with non-specific chronic low back pain. Double blind parallel group randomised controlled trial with six months' follow-up conducted May 2011-March 2013. Participants, physiotherapists, assessors, and analyses were blinded to group allocation. Interdisciplinary chronic pain centre. 135 participants with non-specific chronic low back pain >12 weeks were recruited from 225 patients assessed for eligibility. Participants were randomised to receive anodal (20 minutes to motor cortex at 2 mA) or sham transcranial direct current stimulation (identical electrode position, stimulator switched off after 30 seconds) for five consecutive days immediately before cognitive behavioural management (four week multidisciplinary programme of 80 hours). Two primary outcome measures of pain intensity (0-100 visual analogue scale) and disability (Oswestry disability index) were evaluated at two primary endpoints after stimulation and after cognitive behavioural management. Analyses of covariance with baseline values (pain or disability) as covariates showed that transcranial direct current stimulation was ineffective for the reduction of pain (difference between groups on visual analogue scale 1 mm (99% confidence interval -8.69 mm to 6.3 mm; P=0.68)) and disability (difference between groups 1 point (-1.73 to 1.98; P=0.86)) and did not influence the outcome of cognitive behavioural management (difference between group 3 mm (-10.32 mm to 6.73 mm); P=0.58; difference between groups on Oswestry disability index 0 point (-2.45 to 2.62); P=0.92). The stimulation was well tolerated with minimal transitory side effects. This results of this trial on the effectiveness of transcranial direct current stimulation for the reduction of pain and disability do not support its clinical use for managing non-specific chronic low back pain.Trial registration Current controlled trials ISRCTN89874874. © Luedtke et al 2015.

The potential benefits of combining pain education (PE) with clinical hypnosis (CH) has not yet been investigated in individuals with chronic pain. A total of 100 patients with chronic non-specific low back pain were randomized to receive either (1) PE alone or (2) PE plus CH. Outcomes were collected by a blinded assessor at 2 weeks and 3 months after randomization. The primary outcomes were average pain intensity, worst pain intensity (both assessed with 11-point Numerical Rating Scales), and disability (24-item Roland Morris Disabilty Questionnaire) at 2 weeks. At 2 weeks, participants who received PE plus CH reported lower worst pain intensity (mean difference = 1.35 points, 95% confidence interval [CI] = 0.32 to 2.37) and disability (mean difference = 2.34 points, 95% CI = 0.06 to 4.61), but not average pain intensity (mean difference = 0.67 point, 95% CI = -0.27 to 1.62), relative to participants who received PE alone. PE plus CH participants also reported more global perceived benefits at 2 weeks (mean difference = -1.98 points 95% CI = -3.21 to -0.75). At three months, participants who received PE plus CH reported lower worst pain intensity (mean difference = 1.32 points, 95% CI = 0.29 to 2.34) and catastrophizing (mean difference = 5.30 points, 95% CI = 1.20 to 9.41). No adverse effects in either treatment condition were reported. This is the first trial showing that adding hypnosis to PE results in improved outcomes over PE alone in patients with chronic non-specific low back pain. This trial was prospectively registered at clinicaltrials.gov: NCT02638753 PERSPECTIVE: This study provides evidence supporting the efficacy of another treatment option for teaching patients to self-manage chronic low back pain that has a relatively low cost and that can be offered in groups.

This study estimated the prevalence of chronic back pain among migrant farmworker family members and identified associated work and non-work variables. Migrant farmworkers (n = 390 from 267 families) from Starr County, Texas were interviewed in their home once a year for 2 years. The original survey included items measuring demographics, smoking, sleep, farm work, and chronic back pain. For this cross-sectional analysis, multi-level logistic regression was used to identify associated work and other variables associated with chronic back pain while accounting for intraclass correlations due to repeated measures and multiple family members. The prevalence of chronic back pain during the last migration season ranged from 9.5% among the youngest children to 33.3% among mothers. Variables significantly associated with chronic back pain were age (odds ratio [OR], 1.03, per year increase), depressive symptoms while migrating (OR, 8.72), fewer than 8 hours of sleep at home in Starr County (OR, 2.26), fairly bad/very bad quality of sleep while migrating (OR, 3.25), sorting crops at work (OR, 0.18), and working tree crops (OR, 11.72). The role of work exposures, depressive symptoms, and sleep in chronic back pain among farmworkers warrants further examination. Refinements in outcome and exposure assessments are also needed given the lack of a standardized case definition and the variety of tasks and crops involved in farm work in the United States.

Histone deacetylase inhibitors (HDACi) are being considered to treat chronic inflammatory diseases at low doses. Currently HDACi that are more specific are being developed to target particular HDACs; therefore, this study aimed to determine levels and distribution of class I and II HDAC in human gingival samples obtained from patients with chronic periodontitis. Gingival biopsies were obtained from patients with and without (mild inflammation, no bone loss) periodontitis. Total RNA was isolated for real-time quantitative polymerase chain reaction to determine expression of HDACs 1-10. Immunohistochemistry was used to determine protein distribution of HDACs 1, 5, 8 and 9. Factor VIII, CD3 and tartrate resistant acid phosphatase (TRAP) were detected in serial sections to identify blood vessels, lymphocytes, pre-osteoclasts and osteoclasts cells respectively. Tumour necrosis factor α (TNF-α) expression was also assessed. mRNA for HDAC 1, 5, 8 and 9 were significantly upregulated in chronic periodontitis gingival tissues compared to non-periodontitis samples (p < 0.05). Significantly higher HDAC 1 protein expression was observed in chronic periodontitis samples (p < 0.05), and was associated with CD3, TRAP and TNF-α-positive cells. HDAC 1, 5, 8 and 9 were expressed strongly by the factor VIII-positive microvasculature in the chronic periodontitis gingival tissues. HDAC 1, 5, 8 and 9 expression was higher in gingival tissues from patients with chronic periodontitis compared to non-periodontitis samples. Results suggest that these HDACs could therefore be targeted with specific acting HDACi. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background Smoking, alcohol consumption, poor diet and low levels of physical activity significantly contribute to the burden of illness in developed countries. Whilst the links between specific and multiple risk behaviours and individual chronic conditions are well documented, the impact of these behaviours in mid-life across a range of later life outcomes has yet to be comprehensively assessed. This review aimed to provide an overview of behavioural risk factors in mid-life that are associated with successful ageing and the primary prevention or delay of disability, dementia, frailty and non-communicable chronic conditions. Methods A literature search was conducted to identify cohort studies published in English since 2000 up to Dec 2014. Multivariate analyses and a minimum follow-up of five years were required for inclusion. Two reviewers screened titles, abstracts and papers independently. Studies were assessed for quality. Evidence was synthesised by mid-life behavioural risk for a range of late life outcomes. Findings This search located 10,338 individual references, of which 164 are included in this review. Follow-up data ranged from five years to 36 years. Outcomes include dementia, frailty, disability and cardiovascular disease. There is consistent evidence of beneficial associations between mid-life physical activity, healthy ageing and disease outcomes. Across all populations studied there is consistent evidence that mid-life smoking has a detrimental effect on health. Evidence specific to alcohol consumption was mixed. Limited, but supportive, evidence was available relating specifically to mid-life diet, leisure and social activities or health inequalities. Conclusions There is consistent evidence of associations between mid-life behaviours and a range of late life outcomes. The promotion of physical activity, healthy diet and smoking cessation in all mid-life populations should be encouraged for successful ageing and the prevention of disability and chronic disease.

An association between chronic hepatitis C virus (HCV) infection and essential mixed cryoglobulinaemia and non-Hodgkin lymphoma (NHL) has been suggested. However, a causative role of HCV in these conditions has not been established. The authors report a case of a 50 year-old woman with chronic hepatitis C (CHC) who has been followed up since 1998 due to a high viral load, genotype 1b and moderately elevated liver function tests (LFTs). Laboratory data and liver biopsy revealed moderate activity (grade: 5/18, stage: 1/6). In April 1999, one-year interferon therapy was started. HCV-RNA became negative with normalization of LFTs. However, the patient relapsed during treatment. In September 2002, the patient was admitted for chronic back pain. A CT examination demonstrated degenerative changes. In March 2003, multiple myeloma was diagnosed (IgG-kappa, bone ma-rrow biopsy: 50% plasma cell infiltration). MRI revealed a compression fracture of the 5th lumbar vertebral body and an abdominal mass in the right lower quadrant, infiltrating the canalis spinalis. Treatment with vincristine, adriamycin and dexamethasone (VAD) was started and bisphosphonate was administered regularly. In January 2004, after six cycles of VAD therapy, the multiple myeloma regressed. Thalidomide, as a second line trea-tment of refractory multiple myeloma (MM) was initiated, and followed by peginterferon-α2b and ribavirin against the HCV infection in June. In June 2005, LFTs returned to normal, while HCV-RNA was negative, demonstrating an end of treatment response. Although a pathogenic role of HCV infection in malignant lymphoproliferative disorders has not been established, NHL and possibly MM may develop in CHC patients, supporting a role of a complex follow-up in these patients.

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

The detrimental impact of tobacco on human health is clearly recognized and despite aggressive efforts to prevent smoking, close to one billion individuals worldwide continue to smoke. People with chronic obstructive pulmonary disease (COPD) are susceptible to recurrent respiratory infections with pathogens, including non-typeable Haemophilus influenzae (NTHI), yet the reasons for this increased susceptibility are poorly understood. As mortality rapidly increases with multiple exacerbations, development of protective immunity is critical to improving patient survival. Acute NTHI infection has been studied in the context of cigarette smoke exposure, but this is the first study to investigate chronic infection and the generation of adaptive immune responses to NTHI following chronic smoke exposure. After chronic NTHI infection, mice that had previously been exposed to cigarette smoke developed increased lung inflammation and compromised adaptive immunity relative to air-exposed controls. Importantly, NTHI-specific T cells from mice exposed to cigarette smoke produced lower levels of IFN-γ and IL-4, and B cells produced reduced levels of antibodies against outer membrane lipoprotein P6, with impaired IgG1, IgG2a and IgA class-switching. However, production of IL-17, which is associated with neutrophilic inflammation, was enhanced. Interestingly, cigarette smoke exposed mice exhibited a similar defect in the generation of adaptive immunity following immunization with P6. Our study has conclusively demonstrated that cigarette smoke exposure has a profound suppressive effect on the generation of adaptive immune responses to NTHI and suggests the mechanism by which prior cigarette smoke exposure predisposes COPD patients to recurrent infections, leading to exacerbations and contributing to mortality.

The main focus of Pain Neuroscience Education is around changing patients' pain perceptions and minimizing further medical care. Even though Pain Neuroscience Education has been studied extensively, the experiences of patients regarding the Pain Neuroscience Education process remain to be explored. Therefore, the aim of this study was to explore the experiences in patients with non-specific chronic pain. Fifteen patients with non-specific chronic pain from a transdisciplinary treatment centre were in-depth interviewed. Data collection and analysis were performed according to Grounded Theory. Five interacting topics emerged: (1) "the pre-Pain Neuroscience Education phase", involving the primary needs to provide Pain Neuroscience Education, with subthemes containing (a) "a broad intake" and (b) "the healthcare professionals"; (2) "a comprehensible Pain Neuroscience Education" containing (a) "understandable explanation" and (b) "interaction between the physiotherapist and psychologist"; (3) "outcomes of Pain Neuroscience Education" including (a) "awareness", b) "finding peace of mind", and (c) "fewer symptoms"; 4) "scepticism" containing (a) "doubt towards the diagnosis and Pain Neuroscience Education", (b) "disagreement with the diagnosis and Pain Neuroscience Education", and (c) "Pain Neuroscience Education can be confronting". This is the first study providing insight into the constructs contributing to the Pain Neuroscience Education experience of patients with non-specific chronic pain. The results reveal the importance of the therapeutic alliance between the patient and caregiver, taking time, listening, providing a clear explanation, and the possible outcomes when doing so. The findings from this study can be used to facilitate healthcare professionals in providing Pain Neuroscience Education to patients with non-specific chronic pain. Implications for Rehabilitation An extensive biopsychosocial patient centred intake is crucial prior to providing Pain Neuroscience Education. Repetitions of Pain Neuroscience Education, in different forms (verbal and written information, examples, drawings, etc.) help patients to understand the theory of neurophysiology. Pain Neuroscience Education induces insight into the patient's complaints, improved coping with complaints, improved self-control, and induces in some cases peace of mind. Healthcare professionals providing Pain Neuroscience Education should be aware of the possible confronting nature of the contributing factors.

Over the last decade, there has been a growing interest in the use of interventions that target the intestinal microbiota as a treatment approach for asthma. This study is aimed at exploring the therapeutic effects of long-term treatment with a combination of Bifidobacterium breve with non-digestible oligosaccharides on airway inflammation and remodeling. A murine ovalbumin-induced chronic asthma model was used. Pulmonary airway inflammation; mRNA expression of pattern recognition receptors, Th-specific cytokines and transcription factors in lung tissue; expression of Foxp3 in blood Th cells; in vitro T cell activation; mast cell degranulation; and airway remodeling were examined. The combination of B. breve with non-digestible oligosaccharides suppressed pulmonary airway inflammation; reduced T cell activation and mast cell degranulation; modulated expression of pattern recognition receptors, cytokines and transcription factors; and reduced airway remodeling. The treatment induced regulatory T cell responses, as shown by increased Il10 and Foxp3 transcription in lung tissue, and augmented Foxp3 protein expression in blood CD4+CD25+Foxp3+ T cells. This specific combination of beneficial bacteria with non-digestible oligosaccharides has strong anti-inflammatory properties, possibly via the induction of a regulatory T cell response, resulting in reduced airway remodeling and, therefore, may be beneficial in the treatment of chronic inflammation in allergic asthma.

Background Dietary supplement use in the United States is prevalent and represents an important source of nutrition. However, little is known about individuals who routinely consume multiple dietary supplements. This study describes the dietary supplement usage patterns, health, and nutritional status of long-term multiple dietary supplement users, and where possible makes comparisons to non-users and multivitamin/mineral supplement users. Methods Using a cross-sectional study design, information was obtained by online questionnaires and physical examination (fasting blood, blood pressure, body weight) from a convenience sample of long-term users of multiple dietary supplements manufactured by Shaklee Corporation (Multiple Supp users, n = 278). Data for non-users (No Supp users, n = 602) and multivitamin/mineral supplement users (Single Supp users, n = 176) were obtained from the National Health and Nutrition Examination Survey (NHANES) 2001–2002 and NHANES III 1988–1994. Logistic regression methods were used to estimate odds ratios with 95% confidence intervals. Results Dietary supplements consumed on a daily basis by more than 50% of Multiple Supp users included a multivitamin/mineral, B-complex, vitamin C, carotenoids, vitamin E, calcium with vitamin D, omega-3 fatty acids, flavonoids, lecithin, alfalfa, coenzyme Q10 with resveratrol, glucosamine, and a herbal immune supplement. The majority of women also consumed gamma linolenic acid and a probiotic supplement, whereas men also consumed zinc, garlic, saw palmetto, and a soy protein supplement. Serum nutrient concentrations generally increased with increasing dietary supplement use. After adjustment for age, gender, income, education and body mass index, greater degree of supplement use was associated with more favorable concentrations of serum homocysteine, C-reactive protein, high-density lipoprotein cholesterol, and triglycerides, as well as lower risk of prevalent elevated blood pressure and diabetes. Conclusion This group of long-term multiple dietary supplement users consumed a broad array of vitamin/mineral, herbal, and condition-specific dietary supplements on a daily basis. They were more likely to have optimal concentrations of chronic disease-related biomarkers, and less likely to have suboptimal blood nutrient concentrations, elevated blood pressure, and diabetes compared to non-users and multivitamin/mineral users. These findings should be confirmed by studying the dietary supplement usage patterns, health, and nutritional status of other groups of heavy users of dietary supplements. PMID:17958896

Recent studies in adult patients have established a relationship between hepatitis C virus infection and the presence of liver-kidney microsomal autoantibody type 1 (LKM1). Conversely, little is known regarding the relationship between hepatitis C and autoimmunity in children. In this study, we investigated non-organ specific autoantibodies in 40 otherwise healthy Italian children with chronic hepatitis C. All but four patients included in the study were asymptomatic. Liver histology, obtained in 35, showed features ranging from minimal to mild chronic hepatitis. Autoantibodies were investigated by indirect immunofluorescence. HCV RNA was assayed by the polymerase chain reaction in 34 cases and viral genotypes were determined. Antinuclear antibodies were detected in three (7.5%) cases, one with a homogeneous pattern; smooth muscle autoantibodies in seven (17.5%) cases, always with V (vessels only) specificity and LKM1 in four (10%), at titers ranging from 1:20 and 1:2560. Clinical and virologic features did not significantly differ between autoantibody positive and negative cases, although infections with HCV genotypes 1a and 2 were more frequent in LKM1-positive patients. During observation, the child with the highest LKM1 titre was unsuccessfully treated with alpha interferon but responded to steroids. Twelve LKM1 negative children were also treated with interferon and one developed low LKM1 titers concomitant with an alanine aminotransferase flare. The sera of the five LKM1-positive children with investigated by immunoblotting with a human microsomal fraction and peptide 257-269 of cytochrome P450IID6. Only the serum of the child with the highest LKM1 titers was reactive. These results show that a consistent proportion of children with chronic hepatitis C circulate non-organ specific autoantibodies. The prevalence of LKM1 is greater than in adults and this could raise problems for the treatment of the disease with interferon. The analysis of LKM1 target antigens might help to identify putative cases of "true" autoimmune hepatitis with concomitant HCV infection that could benefit from steroid treatment.

This two-part study analyzed data collected from middle-aged (age 44-64) and older women (age 65+) with one or more chronic conditions who completed the National Council on Aging Chronic Care Survey. Part One analyzed data from 418 women to describe sociodemographics, disease types, and healthcare utilization associated with Internet use among middle-aged and older women with 1 or more chronic diseases. Part Two analyzed data from the 251 Internet-using women to identify the online self-care resources they are using (format, host organization) and for what purposes. Approximately 31% of participants were age 65 years or older, 30% reported having three or more chronic condition types, and 65% reported using the Internet. A significantly larger proportion of older women reported multiple chronic conditions, and a significantly fewer number of older women reported using the Internet. A significantly smaller proportion of Internet users were non-Hispanic white, more educated, and employed. A significantly larger proportion of non-Internet users reported needing help learning what to do to manage their health conditions and needing help learning how to care for their health conditions. Among only Internet-using women, 18.7% participated in online discussions/chatrooms/listserv and 45.2% read about the experiences of others with chronic diseases. Interest in websites and online courses varied. Understanding Internet use among women with chronic conditions can inform targeted efforts to increase Internet availability, educate potential users about the benefits of online resources, and effectively tailor Internet-based materials to self-care needs.

The growing body of research showing increased opioid use in patients with chronic pain coupled with concerns regarding addiction encouraged the development of this population-based study. The goal of the study was to investigate the co-occurrence of indicators of addictive behaviors in patients with chronic non-cancer pain in long-term opioid treatment. The study combined data from the individual-based Danish Health Survey in 2010 and the official Danish health and socio-economic, individual-based registers. From a simple random sample of 25,000 adults (16 years or older) living in Denmark, 13,281 individuals were analyzed through multiple logistic regression analyses to assess the association between chronic pain (lasting ≥6 months), opioid use, health behavior, and body mass index. Six potential addictive behaviors were identified: daily smoking; high alcohol intake; illicit drug use in the past year; obesity; long-term use of benzodiazepines; and long-term use of benzodiazepine-related drugs. At least 2 of the 6 addictive behaviors were observed in 22.6% of the long-term opioid users with chronic pain compared with 11.5% of the non-opioid users with chronic pain and 8.9% of the individuals without chronic pain. Thus, a strong association was demonstrated between long-term opioid use and the clustering of addictive behaviors. An intricate relationship between chronic pain, opioid use, and addictive behaviors was observed in this study, which deserves both clinical attention and further research.

2016-07-01

The U.S. Department of Health and Human Services recently called for a paradigm shift from the study of individual chronic conditions to multiple chronic conditions (MCCs). We identify the most common combinations of chronic diseases experienced by a sample of community-dwelling older people and assess whether depression is differentially associated with combinations of illnesses. Self-reports of diagnosed chronic conditions and depressive symptoms were provided by 5,688 people participating in the ORANJ BOWL(SM) research panel. Each respondent was categorized as belonging to one of 32 groups. ANOVA examined the association between depressive symptoms and combinations of illnesses. People with more health conditions experienced higher levels of depression than people with fewer health conditions. People with some illness combinations had higher levels of depressive symptoms than people with other illness combinations. Findings confirm extensive variability in the combinations of illnesses experienced by older adults and demonstrate the complex associations of specific illness combinations with depressive symptoms. Results highlight the need to expand our conceptualization of research and treatment around MCCs and call for a person-centered approach that addresses the unique needs of individuals with MCCs. © The Author 2016.

Patients with chronic dizziness following traumatic head injury typically have multiple diagnoses involving combined peripheral and central vestibular dysfunction.

2017-04-01

We hypothesised that chronic vestibular symptoms (CVS) of imbalance and dizziness post-traumatic head injury (THI) may relate to: (i) the occurrence of multiple simultaneous vestibular diagnoses including both peripheral and central vestibular dysfunction in individual patients increasing the chance of missed diagnoses and suboptimal treatment; (ii) an impaired response to vestibular rehabilitation since the central mechanisms that mediate rehabilitation related brain plasticity may themselves be disrupted. We report the results of a retrospective analysis of both the comprehensive clinical and vestibular laboratory testing of 20 consecutive THI patients with prominent and persisting vestibular symptoms still present at least 6months post THI. Individual THI patients typically had multiple vestibular diagnoses and unique to this group of vestibular patients, often displayed both peripheral and central vestibular dysfunction. Despite expert neuro-otological management, at two years 20% of patients still had persisting vestibular symptoms. In summary, chronic vestibular dysfunction in THI could relate to: (i) the presence of multiple vestibular diagnoses, increasing the risk of 'missed' vestibular diagnoses leading to persisting symptoms; (ii) the impact of brain trauma which may impair brain plasticity mediated repair mechanisms. Apart from alerting physicians to the potential for multiple vestibular diagnoses in THI, future work to identify the specific deficits in brain function mediating poor recovery from post-THI vestibular dysfunction could provide the rationale for developing new therapy for head injury patients whose vestibular symptoms are resistant to treatment.

Drug abuse is a serious risk factor for the incidence and severity of multiple psychiatric illnesses. Understanding the neurobiological consequences of repeated exposure to abused drugs can help to inform how those risks are manifested in terms of specific neurochemical mechanisms and brain networks. This review examines selective studies in non-human primates that employed a cocaine self-administration model. Neurochemical consequences of chronic exposure appear to differ from observations in rodent studies. Whereas chronic intermittent exposure in the rodent is usually associated with a dose-dependent increase in dopaminergic response to a cocaine challenge, in the rhesus monkey, high cumulative exposure was not observed to cause a sensitized dopamine response. These non-human primate observations are concordant with clinical findings in human users. The results of cue exposure studies on dopaminergic transmission are also reviewed. Direct microdialysis measurements indicate that there is not a sustained increase in dopamine associated with cocaine-linked cues. As an alternative to striatal dopaminergic mechanisms mediating cue effects, single unit studies in prefrontal cortex during self-administration in monkeys suggests the orbitofrontal and anterior cingulate cortex are strongly engaged by cocaine cues. Based on the strong clinical imaging literature on cortical and cognitive dysfunction associated with addiction, it is proposed that the strong engagement of cortical systems during repeated cocaine reinforcement results in maladaptive changes that contribute to the risks of drug use for exacerbation of other psychiatric disorders.

Myalgic encephalomyelitis (ME, also called Chronic Fatigue Syndrome), a common disease with chronic fatigability, cognitive dysfunction and myalgia of unknown etiology, often starts with an infection. The chaperonin human heat shock protein 60 (HSP60) occurs in mitochondria and in bacteria, is highly conserved, antigenic and a major autoantigen. The anti-HSP60 humoral (IgG and IgM) immune response was studied in 69 ME patients and 76 blood donors (BD) (the Training set) with recombinant human and E coli HSP60, and 136 30-mer overlapping and targeted peptides from HSP60 of humans, Chlamydia, Mycoplasma and 26 other species in a multiplex suspension array. Peptides from HSP60 helix I had a chaperonin-like activity, but these and other HSP60 peptides also bound IgG and IgM with an ME preference, theoretically indicating a competition between HSP60 function and antibody binding. A HSP60-based panel of 25 antigens was selected. When evaluated with 61 other ME and 399 non-ME samples (331 BD, 20 Multiple Sclerosis and 48 Systemic Lupus Erythematosus patients), a peptide from Chlamydia pneumoniae HSP60 detected IgM in 15 of 61 (24%) of ME, and in 1 of 399 non-ME at a high cutoff (p<0.0001). IgM to specific cross-reactive epitopes of human and microbial HSP60 occurs in a subset of ME, compatible with infection-induced autoimmunity. PMID:24312270

Cervical and thoracic spinal manipulative therapy has shown positive impact for relief of pain and improve function in non-specific mechanical neck pain. Several attempts have been made to compare their effectiveness although previous studies lacked a control group, assessed acute neck pain or combined thrust and non-thrust techniques. To compare the immediate effects of cervical and thoracic spinal thrust manipulations on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain. Randomized, single-blinded, controlled clinical trial. Private physiotherapy clinical consultancy. Eighty-eight subjects (32.09±6.05 years; 72.7% females) suffering neck pain (grades I or II) of at least 12 weeks of duration. Participants were distributed into three groups: 1) cervical group (N.=28); 2) thoracic group (N.=30); and 3) control group (N.=30). One treatment session consisting of applying a high-velocity low-amplitude spinal thrust technique over the lower cervical spine (C7) or the upper thoracic spine (T3) was performed, while the control group received a sham-manual contact. Measurements were taken at baseline and after intervention of the pressure pain threshold over the median, ulnar and radial nerves. Secondary measures included assessing free-pain grip strength with a hydraulic dynamometer. No statistically significant differences were observed when comparing between-groups in any of the outcome measures (P>0.05). Those who received thrust techniques, regardless of the manipulated area, reported an immediate increase in mechanosensitivity over the radial (both sides) and left ulnar nerve trunks (P<0.05), and grip strength (P<0.001). For those in the control group, right hand grip strength and pain perception over the radial nerve also improved (P≤0.025). Low-cervical and upper-thoracic thrust manipulation is no more effective than placebo to induce immediate changes on mechanosensitivity of upper limb nerve trunks and grip strength in patients with chronic non-specific mechanical neck pain. A single treatment session using cervical or thoracic thrust techniques is not enough to achieve clinically relevant changes on neural mechanosensitivity and grip strength in chronic non-specific mechanical neck pain.

To examine the difference in expression of messenger RNA (mRNA) transcripts for polymeric immunoglobulin receptor (plgR), alpha-chain, and J-chain determined by use of quantitative real-time reverse transcription-polymerase chain reaction (QRT-PCR) assays in duodenal biopsy specimens obtained from dogs with and without chronic diarrhea. Biopsy specimens of the proximal portion of the duodenum were obtained endoscopically from 39 dogs evaluated because of chronic diarrhea (12 German Shepherd Dogs and 27 non-German Shepherd Dog breeds); specimens were also obtained from a control group of 7 dogs evaluated because of other gastrointestinal tract diseases and 2 dogs that were euthanatized as a result of nongastrointestinal tract disease. Dogs were anesthetized, and multiple mucosal biopsy specimens were obtained endoscopically at the level of the caudal duodenal flexure by use of biopsy forceps; in 2 control dogs, samples were obtained from the descending duodenum within 5 minutes of euthanasia. One-step QRT-PCR was used to quantify the level of expression of transcripts for the housekeeper gene glyceraldehyde-3-phosphate dehydrogenase, plgR, alpha-chain, and J-chain in duodenal mucosal tissue. There was no significant difference in the level of expression of any transcript among non-German Shepherd Dog breeds without diarrhea (control group), non-German Shepherd Dog breeds with chronic diarrhea, and German Shepherd Dogs with chronic diarrhea. Conclusions and Clinical Relevance-Results indicated that the susceptibility of German Shepherd Dogs to chronic diarrhea is not a result of simple failure of transcription of the key genes that encode molecules involved in mucosal IgA secretion.

Persons chronically infected with the hepatitis C virus (HCV) may be at higher risk for developing and dying from non-liver cancers than the general population. 12,126 chronic HCV-infected persons in the Chronic Hepatitis Cohort Study (CHeCS) contributed 39,984 person-years of follow-up from 2006 to 2010 and were compared to 133,795,010 records from 13 Surveillance, Epidemiology and End Results Program (SEER) cancer registries, and approximately 12 million U.S. death certificates from Multiple Cause of Death (MCOD) data. Measurements included standardized rate ratios (SRR) and relative risk (RR). The incidence of the following cancers was significantly higher among patients with chronic HCV infection: liver (SRR, 48.6 [95% CI, 44.4-52.7]), pancreas (2.5 [1.7-3.2]), rectum (2.1 [1.3-2.8]), kidney (1.7 [1.1-2.2]), non-Hodgkin lymphoma (NHL) (1.6 [1.2-2.1]), and lung (1.6 [1.3-1.9]). Age-adjusted mortality was significantly higher among patients with: liver (RR, 29.6 [95% CI, 29.1-30.1]), oral (5.2 [5.1-5.4]), rectum (2.6 [2.5-2.7]), NHL (2.3 [2.2-2.31]), and pancreatic (1.63 [1.6-1.7]) cancers. The mean ages of cancer diagnosis and cancer-related death were significantly younger among CHeCS HCV cohort patients compared to the general population for many cancers. Incidence and mortality of many types of non-liver cancers were higher, and age at diagnosis and death younger, in patients with chronic HCV infection compared to the general population.

Palmitoylethanolamide (PEA) and oleoylethanolamide (OEA) are endogenous lipid mediators that suppress inflammation. Their actions are terminated by the intracellular cysteine amidase, N-acylethanolamine acid amidase (NAAA). Even though NAAA may offer a new target for anti-inflammatory therapy, the lipid-like structures and reactive warheads of current NAAA inhibitors limit the use of these agents as oral drugs. A series of novel benzothiazole-piperazine derivatives that inhibit NAAA in a potent and selective manner by a non-covalent mechanism are described. A prototype member of this class (8) displays high oral bioavailability, access to the central nervous system (CNS), and strong activity in a mouse model of multiple sclerosis (MS). This compound exemplifies a second generation of non-covalent NAAA inhibitors that may be useful in the treatment of MS and other chronic CNS disorders. © 2016 WILEY-VCH Verlag GmbH & Co.

The term multimorbidity is usually defined as the coexistence of two or more chronic conditions within an individual, whereas the term comorbidity traditionally describes patients with an index condition and one or more additional conditions. Multimorbidity of chronic conditions markedly worsens outcomes in patients, increases treatment burden and increases health service costs. Although patients with chronic respiratory disease often have physical comorbidities, they also commonly experience psychological problems such as depression and anxiety. Multimorbidity is associated with increased health-care utilisation and specifically with an increased number of prescription drugs in individuals with multiple chronic conditions such as chronic obstructive pulmonary disease. This npj Primary Care Respiratory Medicine Education Section case study involves a patient in a primary care consultation presenting several common diseases prevalent in people of this age. The patient takes nine different drugs at this moment, one or more pills for each condition, which amounts to polypharmacy. The problems related with polypharmacy recommend that a routine medication review by primary care physicians be performed to reduce the risk of adverse effects of polypharmacy among those with multiple chronic conditions. The primary care physician has the challenging role of integrating all of the clinical problems affecting the patient and reviewing all medicaments (including over-the-counter medications) taken by the patient at any point in time, and has the has the key to prevent the unwanted consequences of polypharmacy. Multimorbid chronic disease management can be achieved with the use of care planning, unified disease templates, use of information technology with appointment reminders and with the help of the wider primary care and community teams.

Recent reports indicate a decline in prevalence of classical tropical chronic pancreatitis (TCP). We studied the etiologies and risk factors over a 14-year period at a tertiary care university hospital. We compared the etiology in chronic pancreatitis (CP) patients presenting and followed-up in our Pancreas Clinic over two time periods (2000-06 and 2007-13). Idiopathic chronic pancreatitis (ICP) was the predominant etiology seen over the two time periods. However an increase in prevalence of alcoholic chronic pancreatitis (ACP) during the latter time period suggests that it may be emerging as a dominant etiology over recent years. Hypertriglyceridemia and hyperparathyroidism were uncommon causes of non-alcoholic CP. Autoimmune pancreatitis was noted only during 2007-13, but remains a rare cause of CP. There are multiple risk factors for CP in our population. The high prevalence of ICP indicates need closer examination of risk factors and ICP pathogenesis. ACP appears to be emerging as a dominant cause of CP which suggests a need to reorient preventive strategies.

With the help of differential blood count analysis and velocity of erythrocyte sedimentation (VES), 30 healthy persons (donors), 30 patients with chronic ischemic hearty disease (IHD) and 34 patients with acute myocardial infarction (AMI) underwent the procedure of calculation for leukocyte index (LI), leukocyte intoxication index (LII), leukocyte shift index (LSI), leukocyte and VES ratio (LVESR), leukocytic and granulocytic index (LGI), general index (GI), neurophil-lymphocyte ratio (NLR), neurophil-monocyte ratio (NMR), lymphocyte-monocyte ratio (LMR) and lymphocyte-eosinophil ratio (LER). Unlike healthy people, patients with chronic IHD had higher indices of LVESR, GI and LER while patients with AMI had increasing indices of LII, LSI, NLR, LER and decreasing indices of LI, LGI, GI, LMI. In case of AMI compared with chronic IHD, average indices of LII, LSI, NLR were higher and indices of LI, LGI, LVESR, GI, LMR were lower. The obtained results show expansion of possibilities to get information about the state of non-specific immunologic reactivity in patients with various IHD forms with the help of integral indices in blood leukogram.

Background: Alongside the dramatic increase of older adults in the United States (U.S.), it is projected that the aging population residing in rural areas will continue to grow. As the prevalence of chronic diseases and multiple chronic conditions among adults continues to rise, there is additional need for evidence-based interventions to assist the aging population to improve lifestyle behaviors, and self-manage their chronic conditions. The purpose of this descriptive study was to identify the geospatial dissemination of Chronic Disease Self-Management Education (CDSME) Programs across the U.S. in terms of participants enrolled, workshops delivered, and counties reached. These dissemination characteristics were compared across rurality designations (i.e., metro areas; non-metro areas adjacent to metro areas, and non-metro areas not adjacent to metro areas). Methods: This descriptive study analyzed data from a national repository including efforts from 83 grantees spanning 47 states from December 2009 to December 2016. Counts were tabulated and averages were calculated. Results: CDSME Program workshops were delivered in 56.4% of all U.S. counties one or more times during the study period. Of the counties where a workshop was conducted, 50.5% were delivered in non-metro areas. Of the 300,640 participants enrolled in CDSME Programs, 12% attended workshops in non-metro adjacent areas, and 7% attended workshops in non-metro non-adjacent areas. The majority of workshops were delivered in healthcare organizations, senior centers/Area Agencies on Aging, and residential facilities. On average, participants residing in non-metro areas had better workshop attendance and retention rates compared to participants in metro areas. Conclusions: Findings highlight the established role of traditional organizations/entities within the aging services network, to reach remote areas and serve diverse participants (e.g., senior centers). To facilitate growth in rural areas, technical assistance will be needed. Additional efforts are needed to bolster partnerships (e.g., sharing resources and knowledge), marketing (e.g., tailored material), and regular communication among stakeholders. PMID:28613257

Objective To evaluate the presence, localization, and specificity of structural hypothalamic and whole brain changes in cluster headache and chronic paroxysmal hemicrania (CPH). Methods We compared T1-weighted magnetic resonance images of subjects with cluster headache (episodic n = 24; chronic n = 23; probable n = 14), CPH ( n = 9), migraine (with aura n = 14; without aura n = 19), and no headache ( n = 48). We applied whole brain voxel-based morphometry (VBM) using two complementary methods to analyze structural changes in the hypothalamus: region-of-interest analyses in whole brain VBM, and manual segmentation of the hypothalamus to calculate volumes. We used both conservative VBM thresholds, correcting for multiple comparisons, and less conservative thresholds for exploratory purposes. Results Using region-of-interest VBM analyses mirrored to the headache side, we found enlargement ( p < 0.05, small volume correction) in the anterior hypothalamic gray matter in subjects with chronic cluster headache compared to controls, and in all participants with episodic or chronic cluster headache taken together compared to migraineurs. After manual segmentation, hypothalamic volume (mean±SD) was larger ( p < 0.05) both in subjects with episodic (1.89 ± 0.18 ml) and chronic (1.87 ± 0.21 ml) cluster headache compared to controls (1.72 ± 0.15 ml) and migraineurs (1.68 ± 0.19 ml). Similar but non-significant trends were observed for participants with probable cluster headache (1.82 ± 0.19 ml; p = 0.07) and CPH (1.79 ± 0.20 ml; p = 0.15). Increased hypothalamic volume was primarily explained by bilateral enlargement of the anterior hypothalamus. Exploratory whole brain VBM analyses showed widespread changes in pain-modulating areas in all subjects with headache. Interpretation The anterior hypothalamus is enlarged in episodic and chronic cluster headache and possibly also in probable cluster headache or CPH, but not in migraine.

Changes in skeletal muscle gene expression consequent to altered weight bearing

Skeletal muscle is a dynamic organ that adapts to alterations in weight bearing. This brief review examines changes in muscle gene expression resulting from the removal of weight bearing by hindlimb suspension and from increased weight bearing due to eccentric exercise. Acute (less than or equal to 2 days) non-weight bearing of adult rat soleus muscle alters only the translational control of muscle gene expression, while chronic (greater than or equal to 7 days) removal of weight bearing appears to influence pretranslational, translational, and posttranslational mechanisms of control. Acute and chronic eccentric exercise are associated with alterations of translational and posttranslational control, while chronic eccentric training also alters the pretranslational control of muscle gene expression. Thus alterations in weight bearing influence multiple sites of gene regulation.

Optimal vitamin D status promotes skeletal health and is recommended with specific treatment in individuals at high risk for fragility fractures. A growing body of literature has provided indirect and some direct evidence for possible extraskeletal vitamin D-related effects. Members of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis have reviewed the main evidence for possible proven benefits of vitamin D supplementation in adults at risk of or with overt chronic extra-skeletal diseases, providing recommendations and guidelines for future studies in this field. Robust mechanistic evidence is available from in vitro studies and in vivo animal studies, usually employing cholecalciferol, calcidiol or calcitriol in pharmacologic rather than physiologic doses. Although many cross-sectional and prospective association studies in humans have shown that low 25-hydroxyvitamin D levels (i.e., <50 nmol/L) are consistently associated with chronic diseases, further strengthened by a dose-response relationship, several meta-analyses of clinical trials have shown contradictory results. Overall, large randomized controlled trials with sufficient doses of vitamin D are missing, and available small to moderate-size trials often included people with baseline levels of serum 25-hydroxyvitamin D levels >50 nmol/L, did not simultaneously assess multiple outcomes, and did not report overall safety (e.g., falls). Thus, no recommendations can be made to date for the use of vitamin D supplementation in general, parental compounds, or non-hypercalcemic vitamin D analogs in the prevention and treatment of extra-skeletal chronic diseases. Moreover, attainment of serum 25-hydroxyvitamin D levels well above the threshold desired for bone health cannot be recommended based on current evidence, since safety has yet to be confirmed. Finally, the promising findings from mechanistic studies, large cohort studies, and small clinical trials obtained for autoimmune diseases (including type 1 diabetes, multiple sclerosis, and systemic lupus erythematosus), cardiovascular disorders, and overall reduction in mortality require further confirmation.

Based on two cross-sectional probability samples (Study 1: N = 1,382, Study 2: N = 1,587), we studied the interplay between positive and negative intergroup contact, different types of intergroup emotions (i.e., episodic intergroup emotions encountered during contact and more general chronic intergroup emotions), and outgroup behavior in the context of intergroup relations between non-immigrant Germans and foreigners living in Germany. In Study 1, we showed that positive and negative contact are related to specific episodic intergroup emotions (i.e., anger, fear and happiness). Results of Study 2 indicate an indirect effect of episodic intergroup emotions encountered during contact experiences on specific behavioral tendencies directed at outgroup members via more chronic situation-independent intergroup emotions. As expected, anger predicted approaching (discriminatory) behavioral tendencies (i.e., aggression) while fear predicted avoidance. The results extend the existing literature on intergroup contact and emotions by addressing positive and negative contact simultaneously and differentiating between situation-specific episodic and chronic intergroup emotions in predicting discriminatory behavioral tendencies.

Azithromycin has been shown to improve lung function and reduce the number of pulmonary exacerbations in cystic fibrosis patients. Concerns remain, however, regarding the potential emergence of treatment-related respiratory pathogens. To determine if chronic azithromycin use (defined as thrice weekly administration) is associated with increased rates of detection of eight specific respiratory pathogens. We performed a new-user, propensity-score matched retrospective cohort study utilizing data from the Cystic Fibrosis Foundation Patient Registry. Incident azithromycin users were propensity-score matched 1:1 with contemporaneous non-users. Kaplan-Meier curves and Cox proportional hazards regression were used to evaluate the association between chronic azithromycin use and incident respiratory pathogen detection. Analyses were performed separately for each pathogen, limited to patients among whom that pathogen had not been isolated in the two years prior to cohort entry. After propensity score matching, mean age of the cohorts was ~12 years. Chronic azithromycin users had a significantly lower risk of detection of new methicillin-resistant Staphylococcus aureus, non-tuberculous mycobacteria, and Burkholderia cepacia complex compared to non-users. The risk of acquiring the remaining five pathogens was not significantly different between users and non-users. Using an innovative new-user, propensity-score matched study design to minimize indication and selection biases, we found in a predominantly pediatric cohort that chronic azithromycin users had a lower risk of acquiring several cystic fibrosis-related respiratory pathogens. These results may ease concerns that chronic azithromycin exposure increases the risk of acquiring new respiratory pathogens among pediatric cystic fibrosis patients.

Clinical differentiation between palmar psoriasis and chronic hand eczema may sometimes be a diagnostic challenge; in such cases histopathological analysis helps to differentiate the two conditions. In the present study, palmar psoriasis and chronic hand eczema were investigated using dermoscopy and the significance of specific dermoscopic features was assessed in order to improve their non-invasive differentiation. Ten patients with biopsy-proven palmar psoriasis and 11 patients with biopsy-proven chronic hand eczema were included in the study. We found that the presence of diffuse white scales was significant in palmar psoriasis whereas the presence of yellowish scales, brownish-orange dots/globules and yellowish-orange crusts was significant in chronic hand eczema. © 2015 Japanese Dermatological Association.

Somatic Hypermutation (SHM) refers to the introduction of mutations within rearranged V(D)J genes, a process that increases the diversity of Immunoglobulins (IGs). The analysis of SHM has offered critical insight into the physiology and pathology of B cells, leading to strong prognostication markers for clinical outcome in chronic lymphocytic leukaemia (CLL), the most frequent adult B-cell malignancy. In this paper we present a methodology for integrating multiple immunogenetic and clinocobiological data sources in order to extract features and create high quality datasets for SHM analysis in IG receptors of CLL patients. This dataset is used as the basis for a higher level integration procedure, inspired form social choice theory. This is applied in the Towards Analysis, our attempt to investigate the potential ontogenetic transformation of genes belonging to specific stereotyped CLL subsets towards other genes or gene families, through SHM. The data integration process, followed by feature extraction, resulted in the generation of a dataset containing information about mutations occurring through SHM. The Towards analysis performed on the integrated dataset applying voting techniques, revealed the distinct behaviour of subset #201 compared to other subsets, as regards SHM related movements among gene clans, both in allele-conserved and non-conserved gene areas. With respect to movement between genes, a high percentage movement towards pseudo genes was found in all CLL subsets. This data integration and feature extraction process can set the basis for exploratory analysis or a fully automated computational data mining approach on many as yet unanswered, clinically relevant biological questions.

Stroke prevention in elderly atrial fibrillation patients remains a challenge. There is a high risk of stroke and systemic thromboembolism but also a high risk of bleeding if anticoagulants are prescribed. The elderly have increased chronic kidney disease, coronary artery disease, polypharmacy, and overall frailty. For all these reasons, anticoagulant use is underutilized in the elderly. In this manuscript, the benefits of non-vitamin K antagonist oral anticoagulants compared with warfarin in the elderly patient population with multiple comorbid conditions are reviewed.

We searched MEDLINE and EMBASE for epidemiologic studies on occupational exposure to methylene chloride and risk of cancer. Estimates of study-specific odds ratios (ORs) were calculated using inverse-variance-weighted fixed-effects models and random-effects models. Statistical tests for heterogeneity were applied. We summarized data from five cohort studies and 13 case-control studies. The pooled OR for multiple myeloma was (OR 2.04; 95 % CI 1.31-3.17) in relation to occupational exposure to methylene chloride but not for non-Hodgkin's lymphoma, leukemia, breast, bronchus, trachea and lung, brain and other CNS, biliary passages and liver, prostate, pancreas, and rectum. Furthermore, we focused on specific outcomes for non-Hodgkin's lymphoma and multiple myeloma because of exposure misclassification. The pooling OR for non-Hodgkin's lymphoma and multiple myeloma was 1.42 (95 % CI 1.10-1.83) with moderate degree of heterogeneity among the studies (I (2) = 26.9 %, p = 0.205). We found an excess risk of multiple myeloma. The non-Hodgkin's lymphoma and leukemia that have shown weak effects should be investigated further.

The National Health Interview Survey (NHIS) is a multipurpose household survey of the U.S. civilian non-institutionalized population conducted annually since 1957. From 1986 to 1994, over 450,000 U.S. workers, age 18 years and older, participated in a probability sampling of the entire non-institutionalized U.S. population; variables collected included a range of measures of acute and chronic disability. The objective of the present study was to assess predictors of health status, and acute and chronic disability for farmers and pesticide applicators (pesticide-exposed workers) compared to all other U.S. workers using the 1986-1994 NHIS. After adjustment for sample weights and design effects using SUDAAN, several measures of acute and chronic disability and health status were modeled with multiple logistic regression. Farmers (n = 9576) were significantly older compared to all other U.S. workers (n = 453,219) and pesticide applicators (n = 180). Farmers and pesticide applicators had a higher proportion of males, whites, and Hispanics and were less educated. After adjusting for age, gender, race-ethnicity, and education, compared to all other workers, farmers were significantly less likely to report acute and chronic disability and health conditions, while pesticide applicators were more likely to report chronic disability, health conditions, and poor health. Given the cross-sectional nature of the data and the significant job demands of farming, both leading to a relative healthy worker effect, the present results indicate that at any point in time, farmers report less acute and chronic disability, compared to other U.S. workers, whereas pesticide applicators report similar or poorer health.

This article examines the effects of chronic non-communicable diseases (NCDs) on households' out-of-pocket health expenditures in Sri Lanka. We explore the disease specific impacts on out-of-pocket health care expenses from chronic NCDs such as heart diseases, hypertension, cancer, diabetics and asthma. We use nationwide cross-sectional household income and expenditure survey 2012/2013 data compiled by the department of census and statistics of Sri Lanka. Employing propensity score matching method to account for selectivity bias, we find that chronic NCD affected households appear to spend significantly higher out-of-pocket health care expenditures and encounter grater economic burden than matched control group despite having universal public health care policy in Sri Lanka. The results also suggest that out-of-pocket expenses on medicines and other pharmaceutical products as well as expenses on medical laboratory tests and other ancillary services are particularly higher for households with chronic NCD patients. The findings underline the importance of protecting households against the financial burden due to NCDs.

Chronic traumatic encephalopathy (CTE) is a neuropathologic diagnosis typically made in human brains with a history of repetitive traumatic brain injury (rTBI). It remains unknown whether CTE occurs exclusively after rTBI, or whether a single TBI (sTBI) can cause CTE. Similarly, it is unclear whether impact (eg, motor vehicle accidents) and non-impact (eg, blasts) types of energy transfer trigger divergent or common pathologies. While it is established that a history of rTBI increases the risk of multiple neurodegenerative diseases (eg, dementia, parkinsonism, and CTE), the possible pathophysiologic and molecular mechanisms underlying these risks have yet to be elucidated.

Chronic diseases are major causes of death and disability and often require multiple prescribed medications for treatment and control. Public health emergencies (e.g., disasters due to natural hazards) that disrupt the availability or supply of these medications may exacerbate chronic disease or even cause death. A repository of chronic disease pharmaceuticals and medical supplies organized for rapid response in the event of a public health emergency is desirable. However, there is no science base for determining the contents of such a repository. This study provides the first step in an evidence-based approach to inform the planning, periodic review, and revision of repositories of chronic disease medications. Data from the 2004 National Hospital Ambulatory Medical Care Survey (NHAMCS) were used to examine the prescription medication needs of persons presenting to US hospital emergency departments for chronic disease exacerbations. It was assumed that the typical distribution of cases for an emergency department will reflect the patient population treated in the days after a public health emergency. The estimated numbers of prescribed drugs for chronic conditions that represent the five leading causes of death, the five leading primary diagnoses for physician office visits, and the five leading causes of disease burden assessed by disability-adjusted life years are presented. The 2004 NHAMCS collected data on 36,589 patient visits that were provided by 376 emergency departments. Overall, the five drug classes mentioned most frequently for emergency department visits during 2004 were narcotic analgesics (30.7 million), non-steroidal anti-inflammatory drugs (25.2 million), non-narcotic analgesics (15.2 million), sedatives and hypnotics (10.4 million), and cephalosporins (8.2 million). The drug classes mentioned most frequently for chronic conditions were: (1) for heart disease, antianginal agents/vasodilators (715,000); (2) for cancer, narcotic analgesics (53,000); (3) for stroke, non-narcotic analgesics (138,000); (4) for chronic obstructive pulmonary disease, anti-asthmatics/bronchodilators (3.2 million); and (5) for diabetes, hypoglycemic agents (261,000). Ten medication categories were common across four or more chronic conditions. Persons with chronic diseases have an urgent need for ongoing care and medical support after public health emergencies. These findings provide one evidence-based approach for informing public health preparedness in terms of planning for and review of the prescription medication needs of clinically vulnerable populations with prevalent chronic disease.

The most common instruments developed to assess the functional status of patients with Non specific low back pain is the Roland-Morris Disability Questionnaire (RMDQ). Clinical and epidemiological research related to low back pain in the Gujarati population would be facilitated by the availability of well-established outcome measures. To find the reliability, validity, sensitivity and specificity of the Gujarati version of the RMDQ for use in Non Specific Chronic low back pain. A reliability, validity, sensitivity and specificity study of Gujarati version of the Roland-Morris Disability Questionnaire (RMDQ). Thirty out patients with Non Specific Chronic low back pain were assessed by the RMDQ. Reliability is assessed by using internal consistency and the intra-class correlation coefficient (ICC). Internal construct validity is assessed by RASCH Analysis and external construct validity is assessed by association with pain and spinal movement. Clinical calculator was used to determine the sensitivity and specificity. Internal consistency of the RMDQ is found to be adequate (> 0.65) at both times, with high ICC's also at both time points. Internal construct validity of the scale is good, indicating a single underlying construct. Expected associations with pain and spinal movement confirm external construct validity. The Sensitivity and Specificity at cut off point of 0.5 was 80% and 84% with respectively positive predictive value (PPV) of 83.33% and negative predictive value (NPV) of 80.76%. The Questionnaire is at the ordinal level. The RMDQ is a one-dimensional, ordinal measure, which works well in the Gujarati population.

Chronic fatigue syndrome (CFS) is a heterogeneous disease which presents with pronounced disabling fatigue, sleep disturbances, and cognitive impairment that negatively affects patients' functional capability. CFS remains a poorly defined entity and its etiology is still in question. CFS is neither a novel diagnosis nor a new medical condition. From as early as the eighteenth century, a constellation of perplexing symptoms was observed that resembled symptoms of CFS. Commencing with "febricula" and ending with CFS, many names for the disease were proposed including neurocirculatory asthenia, atypical poliomyelitis, Royal Free disease, effort syndrome, Akureyri disease, Tapanui disease, chronic Epstein-Barr virus syndrome, and myalgic encephalitis. To date, it remains unclear whether CFS has an autoimmune component or is a condition that precedes a full-blown autoimmune disease. Research suggests that CFS may overlap with other diseases including postural orthostatic tachycardia syndrome (POTS), autoimmune syndrome induced by adjuvants (ASIA), and Sjögren's syndrome. Additionally, it has been postulated that the earliest manifestations of some autoimmune diseases can present with vague non-specific symptoms similar to CFS. Sometimes only when exposed to a secondary stimulus (e.g., antigen) which could accelerate the natural course of the disease would an individual develop the classic autoimmune disease. Due to the similarity of symptoms, it has been postulated that CFS could simply be an early manifestation of an autoimmune disease. This paper will provide a historical background review of this disease and a discussion of CFS as an entity overlapping with multiple other conditions.

To establish the effectiveness of walking alone and walking compared to other non-pharmacological management methods to improve disability, quality of life, or function in adults with chronic low back pain. A systematic search of the following databases was undertaken: Medline, Embase, CINAHL, Scopus, Pedro, SportDiscus, Cochrane Central Register of Controlled Trials. The following keywords were used: 'back pain' or 'low back pain' or 'chronic low back pain' and 'walk*' or 'ambulation' or 'treadmill*' or 'pedometer*' or 'acceleromet*' or 'recreational' and 'disability' or 'quality of life' or 'function*'. Primary research studies with an intervention focus that investigated walking as the primary intervention compared to no intervention or any other non-pharmacological method in adults with chronic low back pain (duration >3 months). Seven randomised controlled trials involving 869 participants were included in the review. There was no evidence that walking was more effective than other management methods such as usual care, specific strength exercises, medical exercise therapy, or supervised exercise classes. One study found over-ground walking to be superior to treadmill walking, and another found internet-mediated walking to be more beneficial than non-internet-mediated walking in the short term. There is low quality evidence to suggest that walking is as effective as other non-pharmacological management methods at improving disability, function, and quality of life in adults with chronic low back pain. © The Author(s) 2015.

Upstream interventions – e.g. housing programs and community health worker interventions-address socioeconomic and behavioral factors that influence health outcomes across diseases. Studying these types of interventions in clinical trials raises a methodological challenge: how should researchers measure the effect of an upstream intervention in a sample of patients with different diseases? This paper addresses this question using an illustrative protocol of a randomized controlled trial of collaborative-goal setting versus goal-setting plus community health worker support among patients multiple chronic diseases: diabetes, obesity, hypertension and tobacco dependence. At study enrollment, patients met with their primary care providers to select one of their chronic diseases to focus on during the study, and to collaboratively set a goal for that disease. Patients randomly assigned to a community health worker also received six months of support to address socioeconomic and behavioral barriers to chronic disease control. The primary hypothesis was that there would be differences in patients’ selected chronic disease control as measured by HbA1c, body mass index, systolic blood pressure and cigarettes per day, between the goal-setting alone and community health worker support arms. To test this hypothesis, we will conduct a stratum specific multivariate analysis of variance which allows all patients (regardless of their selected chronic disease) to be included in a single model for the primary outcome. Population health researchers can use this approach to measure clinical outcomes across diseases. PMID:27965180

The pathophysiology of non-specific chronic rhinitis(NSCR) in dogs is still unknown. In this study the possible role of immunological mechanisms in NSCR is examined, by comparing immunoglobulin concentrations in nasal lavage fluids of dogs with NSCR with those of healthy dogs. The immunoglobulin IgA was detected in nasal lavage fluids of both groups of dogs and the differences in relative levels of IgA in dogs with NSCR were not significant. IgM, IgG(a,b), and IgG(d) were detected more frequently in dogs with NSCR (P<0.05), and the relative levels were higher. The presence of IgG(a,b) may indicate the chronic character of rhinitis, and the presence of IgG(d) the possibility of an allergic component in its pathophysiology. The role of IgM is not completely clear.

The aim of this study was to examine postural control in patients with chronic non-specific low back pain (CNRS). Furthermore the influence of visual information (eyes open versus eyes closed) was analyzed. A total of 8 patients with CNRS and 12 healthy control subjects were examined. Surface electromyography (SEMG) recordings were made from 5 trunk and 5 lower limb muscles as well as one hip muscle during application of distal lateral perturbation. Healthy controls (mean ± standard deviation: 96.42±64.77 µV) showed a significantly higher maximum amplitude of the gluteus medius muscle in comparison to patients with CNRS (56.29±39.63 µV). Furthermore activation of several lower limb muscles was found to be dependent on visual information. Patients showed an altered reflex response of the gluteus medius muscle which could be associated with reduced hip stability. © Deutsche Gesellschaft zum Studium des Schmerzes

ProFUSO: Business process and ontology-based framework to develop ubiquitous computing support systems for chronic patients' management.

New advances in telemedicine, ubiquitous computing, and artificial intelligence have supported the emergence of more advanced applications and support systems for chronic patients. This trend addresses the important problem of chronic illnesses, highlighted by multiple international organizations as a core issue in future healthcare. Despite the myriad of exciting new developments, each application and system is designed and implemented for specific purposes and lacks the flexibility to support different healthcare concerns. Some of the known problems of such developments are the integration issues between applications and existing healthcare systems, the reusability of technical knowledge in the creation of new and more sophisticated systems and the usage of data gathered from multiple sources in the generation of new knowledge. This paper proposes a framework for the development of chronic disease support systems and applications as an answer to these shortcomings. Through this framework our pursuit is to create a common ground methodology upon which new developments can be created and easily integrated to provide better support to chronic patients, medical staff and other relevant participants. General requirements are inferred for any support system from the primary attention process of chronic patients by the Business Process Management Notation. Numerous technical approaches are proposed to design a general architecture that considers the medical organizational requirements in the treatment of a patient. A framework is presented for any application in support of chronic patients and evaluated by a case study to test the applicability and pertinence of the solution. Copyright © 2018 Elsevier Inc.

Anti-Donor Immune Responses Elicited by Allogeneic Mesenchymal Stem Cells and Their Extracellular Vesicles: Are We Still Learning?

PubMed Central

2017-01-01

Mesenchymal stromal cells (MSC) have been used to treat a broad range of disease indications such as acute and chronic inflammatory disorders, autoimmune diseases, and transplant rejection due to their potent immunosuppressive/anti-inflammatory properties. The breadth of their usage is due in no small part to the vast quantity of published studies showing their ability to modulate multiple immune cell types of both the innate and adaptive immune response. While patient-derived (autologous) MSC may be the safer choice in terms of avoiding unwanted immune responses, factors including donor comorbidities may preclude these cells from use. In these situations, allogeneic MSC derived from genetically unrelated individuals must be used. While allogeneic MSC were initially believed to be immune-privileged, substantial evidence now exists to prove otherwise with multiple studies documenting specific cellular and humoral immune responses against donor antigens following administration of these cells. In this article, we will review recent published studies using non-manipulated, inflammatory molecule-activated (licensed) and differentiated allogeneic MSC, as well as MSC extracellular vesicles focusing on the immune responses to these cells and whether or not such responses have an impact on allogeneic MSC-mediated safety and efficacy.

Persons with behavioral disorders incur higher healthcare costs. Although they utilize behavioral health (BH) services others do not, they also have higher utilization of medical services : To determine the degree to which higher costs for persons with BH disorders are attributable to utilization of BH services, multiple chronic medical conditions (CMCs) or other issues specific to populations with BH disorders. Data base consisted of claims for 63,141 Medicaid beneficiaries, 49% of whom had one of 5 categories of BH disorder. Generalized linear models were used to identify relative impact of demographics, BH status, multiple CMCs and primary care access on total, behavioral, nonbehavioral, and medical/surgical costs. Number of CMCs was associated with significant increases in all cost categories, including behavioral costs. Presence of any BH disorder significantly influenced these same costs, including those not associated with BH care. Effect size in each cost category varied by BH group. BH status has a large impact on all healthcare costs, including costs of medical and other non-BH services. The number of CMCs affects BH costs independent of BH disorder. Results suggest that costs might be reduced through better integration of behavioral and medical health services.

Multiple sclerosis (MS) affects approximately 400,000 people in the United States and 2.1 million people worldwide. It is the most common chronic, non-traumatic neurological disorder afflicting young people during their peak productive ages. MS can diminish quality of life (QOL) by interfering with the ability to work, pursue leisure activities, and carry on usual life roles. Symptoms that affect QOL may include impaired mobility, fatigue, depression, pain, spasticity, cognitive impairment, sexual dysfunction, bowel and bladder dysfunction, vision and hearing problems, seizures, and sDwallowing and breathing difficulties. Direct medical costs of MS in the United States are estimated in excess of $10 billion per year. Indirect costs of MS include costs of reduced employment or unemployment, assistive equipment, disability related home modifications, and paid and unpaid personal care. Although direct medical costs predominate in the earlier stages of MS, indirect costs of productivity loss are responsible for higher costs later. Disease-modifying therapies (DMTs) lessen symptoms, reduce relapses, and delay disability progression. Unfortunately, many DMTs might produce only modest improvements in QOL. Although symptom-specific therapies do not delay disease progression, they may delay unemployment and dependency, thereby reducing indirect costs.

Significant survival prolongation in HIV-infected patients due to effective antiretroviral therapy is connected with increasing prevalence of chronic non-infective diseases in this population, among them chronic kidney disease. The pathogenesis of kidney disease in the setting of HIV includes conditions specific for HIV infection: direct effect of the virus, stage of immunodeficiency and drug toxicity. Chronic comorbidities, such as diabetes mellitus, hypertension, and hyperlipidemia, are additional significant risk factors of kidney disease. In HIV-infected individuals some distinct features of these conditions are observed, which are partly related to the virus and antiretroviral therapy. The article summarizes the effect of comorbidities on kidney function in HIV-infected persons.

Multiple imputation of covariates by fully conditional specification: Accommodating the substantive model

PubMed Central

Seaman, Shaun R; White, Ian R; Carpenter, James R

2015-01-01

Missing covariate data commonly occur in epidemiological and clinical research, and are often dealt with using multiple imputation. Imputation of partially observed covariates is complicated if the substantive model is non-linear (e.g. Cox proportional hazards model), or contains non-linear (e.g. squared) or interaction terms, and standard software implementations of multiple imputation may impute covariates from models that are incompatible with such substantive models. We show how imputation by fully conditional specification, a popular approach for performing multiple imputation, can be modified so that covariates are imputed from models which are compatible with the substantive model. We investigate through simulation the performance of this proposal, and compare it with existing approaches. Simulation results suggest our proposal gives consistent estimates for a range of common substantive models, including models which contain non-linear covariate effects or interactions, provided data are missing at random and the assumed imputation models are correctly specified and mutually compatible. Stata software implementing the approach is freely available. PMID:24525487

Coping mediates the relationship between sense of coherence and mental quality of life in patients with chronic illness: a cross-sectional study.

The aim of the present study was to investigate relationships between sense of coherence, emotion-focused coping, problem-focused coping, coping efficiency, and mental quality of life (QoL) in patients with chronic illness. A model based on Lazarus' and Folkman's stress and coping theory tested the specific hypothesis: Sense of coherence has a direct and indirect effect on mental QoL mediated by emotion-focused coping, problem-focused coping, and coping efficiency in serial adjusted for age, gender, educational level, comorbidity, and economic status. The study used a cross-sectional and correlational design. Patients (n = 292) with chronic diseases (chronic heart failure, end-stage renal disease, multiple sclerosis, stroke, and Parkinson) completed three questionnaires and provided background data. Data were collected in 2012, and a serial multiple mediator model was tested using PROCESS macro for SPSS. The test of the conceptual model confirmed the hypothesis. There was a significant direct and indirect effect of sense of coherence on mental QoL through the three mediators. The model explained 39% of the variance in mental QoL. Self-perceived effective coping strategies are the most important mediating factors between sense of coherence and QoL in patients with chronic illness, which supports Lazarus' and Folkman's stress and coping theory.

Serum neuron specific enolase - a novel indicator for neuropsychiatric systemic lupus erythematosus?

2015-12-01

Neuropsychiatric (NP) lupus, a common manifestation of systemic lupus erythematosus (SLE), is still insufficiently understood, in part, because of the lack of specific biomarkers. Neuron specific enolase (NSE), an important neuronal glycolytic enzyme, shows increased serum levels following acute brain injury, and decreased serum levels in several chronic disorders of the nervous system, including multi infarct dementia, multiple sclerosis and depression. The aim of the study was to evaluate serum NSE levels in SLE patients with and without nervous system involvement, and in healthy controls, and to assess the correlation of NSE serum levels of patients with neuropsychiatric systemic lupus erythematosus (NPSLE) with clinical parameters. The study comprised 47 SLE patients and 28 controls. SLE activity was assessed using the Systemic Lupus Activity Measure (SLAM). A neurologist and a psychiatrist examined all patients. NP involvement was diagnosed according to strict NPSLE criteria proposed by Ainiala and coworkers, as modification to American College of Rheumatology (ACR) nomenclature and case definitions. NSE serum levels were determined by use of an immunoassay. Mean NSE serum concentrations in patients with NPSLE were significantly lower than in non-NPSLE patients (6.3 ± 2.6 µg/L vs. 9.7 ± 3.3 µg/L, p < 0.01) and in controls (8.8 ± 3.3 µg/L, p < 0.05). There were significant negative correlations between NSE serum levels and SLE activity (r = -0.42, p < 0.05) and the number of NPSLE manifestations diagnosed (-0.37; p = 0.001). Decreased serum concentrations of NSE may reflect chronic neuronal damage with declined metabolism of the nervous tissue in patients with NPSLE. © The Author(s) 2015.

The Veterans Affairs North Texas Health Care System in Dallas, TX, provides a unique opportunity for clinical pharmacists to work as providers. Even though clinical pharmacists are actively involved in patient care, many of their efforts remain undocumented, resulting in an underestimation of the importance of their services and missed opportunities for improvements and new directions. To document and evaluate the services of a hematology/oncology clinical pharmacy in the outpatient setting. Pendragon Forms 3.2 software was used to design the documentation template. The template was designed to collect diagnoses, supportive care issues, drug-specific interventions, and prescriptions written. This template was uploaded to the personal digital assistant (PDA) for documentation. Patient-specific information was documented in a password-protected PDA. Data collected from November 1, 2002, to October 31, 2003, were retrospectively analyzed. Clinical pharmacists were involved in 423 patient visits for chemotherapy follow-up or disease management. Cancer diagnoses included colorectal (n = 99), multiple myeloma (59), non-small cell lung (56), chronic lymphocytic leukemia (44), myelodysplastic syndromes (22), and chronic myelogenous leukemia (19). During the 423 patient visits, 342 supportive care issues were addressed including anemia (34%), pain management (22%), constipation/diarrhea (15%), and nausea/vomiting (8%). Major drug-specific interventions included drug addition (41%), discontinuation (23%), and adjustment (21%). Four hundred forty-five prescriptions were filled, of which 181 were new and 150 were refilled. This is the first study, as of July 25, 2006, to document considerable contribution of an outpatient clinical pharmacist in direct cancer patient care. Although the disease management and supportive care issues addressed here may differ based on institution and patient population, the results of our study show that clinical pharmacists have ever-growing roles in the management of these patients.

Mediterranean Diet and Prevention of Chronic Diseases

PubMed Central

Romagnolo, Donato F.; Selmin, Ornella I.

2017-01-01

A large body of research data suggests that traditional dietary habits and lifestyle unique to the Mediterranean region (Mediterranean diet, MD) lower the incidence of chronic diseases and improve longevity. These data contrast with troubling statistics in the United States and other high income countries pointing to an increase in the incidence of chronic diseases and the projected explosion in cost of medical care associated with an aging population. In 2013, the MD was inscribed by UNESCO in the “Representative List of the Intangible Cultural Heritage of Humanity.” The 2015–2020 Dietary Guidelines for Americans included the MD as a healthy dietary pattern. Therefore, specific objectives of this article are to provide an overview of the nutritional basis of this healthful diet, its metabolic benefits, and its role in multiple aspects of disease prevention and healthy aging. Whereas recommendations about the MD often focus on specific foods or bioactive compounds, we suggest that the eating pattern as a whole likely contributes to the health promoting effects of the MD.

Treatment of chronic extensor tendons lesions of the fingers.

PubMed

Bellemère, P

2015-09-01

Chronic finger extensor apparatus injuries are the result of the initial acute treatment having failed or being flawed. Because of their chronic nature, these injuries present various amounts of tendon retraction, tendon callus lengthening, peritendinous scar adhesions, static and dynamic imbalances with the flexor apparatus and intrinsic muscles, and joint contractures. This article will review the anatomy of the extensor mechanism and then will outline by location, the various clinical pictures that are secondary to chronic tendon injury. The clinical presentation of these injuries can be highly variable but their symptomatology and treatment are very specific. Of the possible therapeutic strategies for chronic mallet finger with or without associated swan-neck deformity, chronic boutonniere deformity, chronic sagittal band injuries, old ruptures on the dorsum of the wrist and traumatic defects in multiple tissues, conservative treatment is often the main element. Secondary surgical repair is not free of complications, and the results are often lacking. Rehabilitation and orthotic bracing are an integral part of the management of these injuries, no matter which treatment method is being considered. Copyright © 2015 Elsevier Masson SAS.

Psychological and neural mechanisms of the affective dimension of pain are known to be disturbed in patients with chronic pain disorder. The aim of this functional magnetic resonance imaging study was to assess the neurofunctional and behavioral measures underlying the ability to construct pain-related affective meaning in a painful situation by comparing 21 clinically and psychometrically well-characterized patients with persistent non-nociceptive somatoform pain with 19 healthy controls. The functional magnetic resonance imaging task involved viewing pictures depicting human hands and feet in different painful and nonpainful situations. Participants were asked to estimate the perceived pain intensity. These data were correlated with behavioral measures of depression, alexithymia, and general cognitive and emotional empathy. In a hypothesis-driven region-of-interest analysis, the healthy control group exhibited greater activation of the left perigenual anterior cingulate cortex than patients with pain (Montreal Neurological Institute coordinates (x y z)=-8 38 0; cluster extent=54 voxels; T=4.28; p=.006 corrected for multiple comparisons at cluster level). No group differences in the activation of the anterior insular cortex were found. Scores on self-assessment instruments (Beck Depression Inventory I, Interpersonal Reactivity Index, and 20-item Toronto Alexithymia Scale) did not influence neuroimaging results. Our results suggest that patients with chronic medically unexplained pain have an altered neural pain perception process owing to decreased activation of empathetic-affective networks, which we interpret as a deficit in pain-related affective meaning construction. These findings may lead to a more specific and detailed neurobiological understanding of the clinical impression of disturbed affect in patients with chronic pain disorder.

A case of non-Hodgkin lymphoma in a patient with chronic myeloid leukemia.

Chronic myeloid leukemia is a clonal expansion of hematopoietic progenitor cells characterized by exaggerated proliferation of granulocytic lineage, with chronic phase, accelerated phase and blast crisis. Accelerated phase and blast crisis may be associated with extramedulary disease. Extramedullary transformation of CML can be determined both in nodal and extranodal sites. Non-Hodgkin lymphoma is rare in chronic myeloid leukemia and may be misdiagnosed as an extramedullary lymphoid blast transformation; the majorities are T-cell lymphomas with an immature thymic phenotype, while peripheral B-cell lymphomas are rarer. We report the case of a 79-year-old woman carrier Ph+ chronic myeloid leukemia who developed at eight months of diagnosis an accelerated phase of CML associated simultaneous with a tumor of soft palate, which was initial considering an extramedullary disease. The patient was treated with specific chemotherapy for accelerated phase of CML (Cytosinarabinoside) + Anagrelide, and reversed to secondary chronic phase of CML, but soft palate tumor persists. The immunohistochemical findings of bone marrow trephine biopsy examination showed chronic phase of CML (negativity for immature cells such as CD34, Tdt) and the biopsy of soft palate tumor and immunohistochemical findings revealed a primitive non-Hodgkin lymphoma (NHL) with medium B-cells (CD20, CD79a positive) and excluding an extramedullary blast crisis (CD34 negative, Tdt negative). Cytogenetic analysis in tumor revealed absence of Philadelphia chromosome. The patient was treated with local radiotherapy for NHL, with a favorable evolution and Hydroxyurea 1 g/day for CML with hematological remission. A localized lymphoid neoplasm may be an extramedullary localized blast crisis of CML or a distinct malignancy, with distinguished therapy and prognosis. A correct diagnosis based on a complex investigation: immunohistochemistry, conventional cytogenetic analysis and fluorescence in situ hybridization (FISH), molecular analysis (Southern blot and RT-PCR) is necessary. Further studies are required to clarify the pathogenetic relationship between chronic myeloid leukemia and non-Hodgkin lymphomas.

Chronic social isolation causes severe psychological effects in humans, but their neural bases remain poorly understood. 2 weeks (but not 24 hr) of social isolation stress (SIS) caused multiple behavioral changes in mice and induced brain-wide upregulation of the neuropeptide tachykinin 2 (Tac2)/neurokinin B (NkB). Systemic administration of an Nk3R antagonist prevented virtually all of the behavioral effects of chronic SIS. Conversely, enhancing NkB expression and release phenocopied SIS in group-housed mice, promoting aggression and converting stimulus-locked defensive behaviors to persistent responses. Multiplexed analysis of Tac2/NkB function in multiple brain areas revealed dissociable, region-specific requirements for both the peptide and its receptor in different SIS-induced behavioral changes. Thus, Tac2 coordinates a pleiotropic brain state caused by SIS via a distributed mode of action. These data reveal the profound effects of prolonged social isolation on brain chemistry and function and suggest potential new therapeutic applications for Nk3R antagonists.

Impact of antiretroviral therapy (ART) timing on chronic immune activation/inflammation and end-organ damage.

2015-01-01

The purpose of this review was to summarize recent studies on the effect of early antiretroviral therapy (ART) in HIV-infected patients on markers of immune activation/inflammation, viral persistence and serious non-AIDS events. Early ART, initiated within days to months of HIV infection, was associated with marked reduction in T-cell activation often reaching levels observed in HIV-uninfected individuals. However, the impact of early ART on markers of innate immune activation, microbial translocation and inflammation/coagulation was less clear. Early ART has also been associated with a significant reduction in the frequency of latently infected cells, which was greater if ART was initiated within days to weeks rather than months following infection. However, few studies have evaluated the relationship between immune activation and viral reservoirs, specifically following early ART. Early ART may potentially reduce serious non-AIDS events and associated mortality, but most of these studies have extrapolated from changes in surrogate markers, such as CD4 : CD8 ratio. Early ART was associated with beneficial effects on multiple markers of immune activation, inflammation and viral persistence. Longer term prospective studies are still needed to determine whether early ART translates to a significant reduction in serious non-AIDS events and mortality.

Low back pain (LBP) is a common pain syndrome in athletes, responsible for 28% of missed training days/year. Psychosocial factors contribute to chronic pain development. This study aims to investigate the transferability of psychosocial screening tools developed in the general population to athletes and to define athlete-specific thresholds. Data from a prospective multicentre study on LBP were collected at baseline and 1-year follow-up (n=52 athletes, n=289 recreational athletes and n=246 non-athletes). Pain was assessed using the Chronic Pain Grade questionnaire. The psychosocial Risk Stratification Index (RSI) was used to obtain prognostic information regarding the risk of chronic LBP (CLBP). Individual psychosocial risk profile was gained with the Risk Prevention Index - Social (RPI-S). Differences between groups were calculated using general linear models and planned contrasts. Discrimination thresholds for athletes were defined with receiver operating characteristics (ROC) curves. Athletes and recreational athletes showed significantly lower psychosocial risk profiles and prognostic risk for CLBP than non-athletes. ROC curves suggested discrimination thresholds for athletes were different compared with non-athletes. Both screenings demonstrated very good sensitivity (RSI=100%; RPI-S: 75%-100%) and specificity (RSI: 76%-93%; RPI-S: 71%-93%). RSI revealed two risk classes for pain intensity (area under the curve (AUC) 0.92(95% CI 0.85 to 1.0)) and pain disability (AUC 0.88(95% CI 0.71 to 1.0)). Both screening tools can be used for athletes. Athlete-specific thresholds will improve physicians' decision making and allow stratified treatment and prevention.

The nasal mucosa is one of the anatomical region which have the highest density of sensory innervation. The function of this sensory innervation is probably linked to the protection of the lower airways against inhalation of airborne particles and potentially harmful substances. Chronic rhinosinusitis (CRS) is associated with nasal obstruction, rhinorrhea, loss of sense of smell and facial pain or headaches. When allergy or specific hyperreactivity, infection, systemic or genetic deseases have been excluded, the diagnosis of non specific hyperreactivity or neurogenic inflammation is proposed. Sensory neuropeptides released by sensory nerves endings have powerful proinflammatory effects. The best treatment yet available include nasal lavages and the local application of topical corticosteroid spray.

Multiple traumatic and non-traumatic adrenal emergencies are occasionally encountered during the cross-sectional imaging of emergency department patients. Traumatic adrenal hematomas are markers of severe polytrauma, and can be easily overlooked due to multiple concomitant injuries. Patients with non-traumatic adrenal emergencies usually present to an emergency department with a non-specific clinical picture. The detection and management of adrenal emergencies is based on cross-sectional imaging. Adrenal hemorrhage, adrenal infection, or rupture of adrenal neoplasm require immediate detection to avoid dire consequences. More often however, adrenal emergencies are detected incidentally in patients being investigated for non-specific acute abdominal pain. A high index of suspicion is required for the establishment of timely diagnosis and to avert potentially life-threatening complications. We describe cross-sectional imaging findings in patients with traumatic and non-traumatic adrenal hemorrhage, adrenal infarctions, adrenal infections, and complications of adrenal masses.

Effect of classification-specific treatment on lumbopelvic motion during hip rotation in people with low back pain

2010-01-01

Increased and early lumbopelvic motion during trunk and limb movements is thought to contribute to low back pain (LBP). Therefore, reducing lumbopelvic motion could be an important component of physical therapy treatment. Our purpose was to examine the effects of classification-specific physical therapy treatment (Specific) based on the Movement System Impairment (MSI) model and non-specific treatment (Non-Specific) on lumbopelvic movement patterns during hip rotation in people with chronic LBP. We hypothesized that following treatment people in the Specific group would display decreased lumbopelvic rotation and achieve more hip rotation before lumbopelvic rotation began. We hypothesized that people in the Non-Specific group would display no change in these variables. Kinematic data collected before and after treatment for hip lateral and medial rotation in prone were analyzed. The Specific group (N=16) demonstrated significantly decreased lumbopelvic rotation and achieved greater hip rotation before the onset of lumbopelvic rotation after treatment with both hip lateral and medial rotation. The Non-Specific group (N=16) demonstrated significantly increased lumbopelvic rotation and no change in hip rotation achieved before the onset of lumbopelvic rotation. People who received treatment specific to their MSI LBP classification displayed decreased and later lumbopelvic motion with hip rotation, whereas people who received generalized non-specific treatment did not.

Muscle Control and Non-specific Chronic Low Back Pain.

Russo, Marc; Deckers, Kristiaan; Eldabe, Sam; Kiesel, Kyle; Gilligan, Chris; Vieceli, John; Crosby, Peter

2018-01-01

Chronic low back pain (CLBP) is the most prevalent of the painful musculoskeletal conditions. CLBP is a heterogeneous condition with many causes and diagnoses, but there are few established therapies with strong evidence of effectiveness (or cost effectiveness). CLBP for which it is not possible to identify any specific cause is often referred to as non-specific chronic LBP (NSCLBP). One type of NSCLBP is continuing and recurrent primarily nociceptive CLBP due to vertebral joint overload subsequent to functional instability of the lumbar spine. This condition may occur due to disruption of the motor control system to the key stabilizing muscles in the lumbar spine, particularly the lumbar multifidus muscle (MF). This review presents the evidence for MF involvement in CLBP, mechanisms of action of disruption of control of the MF, and options for restoring control of the MF as a treatment for NSCLBP. Imaging assessment of motor control dysfunction of the MF in individual patients is fraught with difficulty. MRI or ultrasound imaging techniques, while reliable, have limited diagnostic or predictive utility. For some patients, restoration of motor control to the MF with specific exercises can be effective, but population results are not persuasive since most patients are unable to voluntarily contract the MF and may be inhibited from doing so due to arthrogenic muscle inhibition. Targeting MF control with restorative neurostimulation promises a new treatment option. © 2017 The Authors.

We report a case of a 46-year-old Vietnamese man who developed widespread, numerous and concurrent cutaneous squamous cell carcinomas (SCCs) in non-sun exposed skin areas after taking a traditional medicine (TM) formulation for chronic plaque psoriasis. The SCC lesions began to develop within 12-15 months after beginning the arsenic-containing TM. The patient experienced both acute and chronic symptoms consistent with arsenic exposure. Laboratory investigation of a collected hair sample showed a significant arsenic level. The TM formulation used by the patient was tested and demonstrated an extremely high concentration of arsenic. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

The multiple-hit pathogenesis of non-alcoholic fatty liver disease (NAFLD).

2016-08-01

Nonalcoholic fatty liver disease (NAFLD) is increasingly prevalent and represents a growing challenge in terms of prevention and treatment. Despite its high prevalence, only a small minority of affected patients develops inflammation and subsequently fibrosis and chronic liver disease, while most of them only exhibit simple steatosis. In this context, the full understanding of the mechanisms underlying the development of NAFLD and non-alcoholic steatohepatitis (NASH) is of extreme importance; despite advances in this field, knowledge on the pathogenesis of NAFLD is still incomplete. The 'two-hit' hypothesis is now obsolete, as it is inadequate to explain the several molecular and metabolic changes that take place in NAFLD. The "multiple hit" hypothesis considers multiple insults acting together on genetically predisposed subjects to induce NAFLD and provides a more accurate explanation of NAFLD pathogenesis. Such hits include insulin resistance, hormones secreted from the adipose tissue, nutritional factors, gut microbiota and genetic and epigenetic factors. In this article, we review the factors that form this hypothesis. Copyright © 2016 Elsevier Inc. All rights reserved.

The Chronic Disease Self-Management Program (CDSMP) was developed to advance participants' self-care of chronic illness and may be offered to both individuals with chronic conditions and their caregivers. Previous studies of CDSMP have identified multiple resulting health benefits for participants as well as factors associated with participants' completion rates. This study investigated differences on these issues between caregiving and non-caregiving participants. Secondary analysis using regression analysis to predict the outcome. Baseline data were collected directly from adult (over 18 years) participants of CDSMP workshops in New York State from 2012 to 2015 (n = 2685). Multi-level logistic regression analysis was used to compare the difference on completion of workshops (attended four or more of sessions) and contributing factors with the independent variable of whether participants provided care/assistance to a family member or friends with long-term illness or disability. Additional individual-level variables controlled for in the model were age, gender, race/ethnicity, living arrangement, education, the number of chronic conditions and disabilities; as were workshop-level characteristics of class size, language used, workshop leader experience, location urbanity and delivery site type. Participants who provided care to family or friends were 28% more likely to complete the workshop compared with those who did not (odds ratio = 1.279, P < 0.05). Different factors influenced the completion of CDSMP workshop for caregivers and non-caregivers. People who provide care to others appeared to have stronger motivation to complete the workshops with greater benefits. Agencies offering CDSMP should encourage caregivers to attend.

2004-07-01

Little attention has been paid to the specific problems of mothers with chronic illness. In this study of mothers with asthma, we asked the question: "how do they manage their illness"? We interviewed a purposive sample of four Dutch and four Canadian mothers living with asthma and varying in age and socio-economic class. Our analysis explored challenges the mothers face, three main strategies of non-medical illness management (prevention, normalization and mobilizing support), and the influence of age and class differences. Unhealthy cycles of living with asthma are identified and suggestions for mother-specific interventions are offered. By drawing attention to the gendered nature of chronic illness management and to patients' own experiences, a more useful frame of reference is created for professionals who do not have first hand knowledge of living with a chronic illness.

[Lyme disease--clinical manifestations and treatment].

PubMed

Stock, Ingo

2016-05-01

Lyme disease (Lyme borreliosis) is a systemic infectious disease that can present in a variety of clinical manifestations. The disease is caused by a group of spirochaetes--Borrelia burgdorferi sensu lato or Lyme borrelia--that are transmitted to humans by the bite of Ixodes ticks. Lyme disease is the most common arthropode-borne infectious disease in many European countries including Germany. Early localized infection is typically manifested by an erythema migrans skin lesion, in rarer cases as a borrelial lymphocytoma. The most common early disseminated manifestation is (early) neuroborreliosis. In adults, neuroborreliosis appears typically as meningoradiculoneuritis. Neuroborreliosis in children, however, is typically manifested by meningitis. In addition, multiple erythema migrans lesions and Lyme carditis occur relatively frequently. The most common manifestation oflate Lyme disease is Lyme arthritis. Early manifestations (and usually also late manifestations) of Lyme disease can be treated successfully by application of suitable antibacterial agents. For the treatment of Lyme disease, doxycycline, certain penicillins such as amoxicillin and some cephalosporins (ceftriaxone, cefotaxime, cefuroxime axetil) are recommended in current guidelines. A major challenge is the treatment of chronic, non-specific disorders, i. e., posttreatment Lyme disease syndrome and "chronic Lyme disease". Prevention of Lyme disease is mainly accomplished by protecting against tick bites. Prophylactic administration of doxycycline after tick bites is generally not recommended in Germany. There is no vaccine available for human beings.

Postural sensorimotor training versus sham exercise in physiotherapy of patients with chronic non-specific low back pain: An exploratory randomised controlled trial

Sensorimotor training (SMT) is popularly applied as exercise in rehabilitation settings, particularly for musculoskeletal pain. With insufficient evidence on its effect on pain and function, this exploratory randomised controlled trial investigated the potential effects of SMT in rehabilitation of chronic non-specific low back pain. Two arms received 9x30 minutes physiotherapy with added interventions: The experimental arm received 15 minutes of postural SMT while the comparator arm performed 15 minutes of added sub-effective low-intensity training. A treatment blinded tester assessed outcomes at baseline 2–4 days prior to intervention, pre- and post-intervention, and at 4-week follow-up. Main outcomes were pain and functional status assessed with a 0–100mm visual analogue scale and the Oswestry Disability Questionnaire. Additionally, postural control was analysed using a video-based tracking system and a pressure plate during perturbed stance. Robust, nonparametric multivariate hypothesis testing was performed. 22 patients (11 females, aged 32 to 75 years) with mild to moderate chronic pain and functional limitations were included for analysis (11 per arm). At post-intervention, average values of primary outcomes improved slightly, but not to a clinically relevant or statistically significant extent. At 4-week follow-up, there was a significant improvement by 12 percentage points (pp) on the functional status questionnaire in the SMT-group (95% confidence intervall (CI) = 5.3pp to 17.7pp, p < 0.001) but not in the control group (4 pp improvement, CI = 11.8pp to 19.2pp). However, group-by-time interaction effects for functional status (Q = 3.3, 19 p = 0.07) and pain (Q = 0.84, p = 0.51) were non-significant. Secondary kinematic outcomes did not change over time in either of the groups. Despite significant improvement of functional status after SMT, overall findings of this exploratory study suggest that SMT provides no added benefit for pain reduction or functional improvement in patients with moderate chronic non-specific low back pain.

Whether chronic HCV, a disease characterized by systemic inflammation, impacts bone mineral density (BMD) independent of cirrhosis is unknown. We aimed to evaluate the association between BMD, systemic inflammation, and markers of bone turnover in chronic HCV without cirrhosis. Non-cirrhotics, 40-60 years old, with chronic HCV underwent measurement of: (1) BMD by dual-energy X-ray absorptiometry scan and (2) serum markers of systemic inflammation and bone turnover. By Chi-squared or t test, we compared those with normal versus low BMD. Of the 60 non-cirrhotics, 53 % were female and 53 % Caucasian. Mean (SD) age was 53.3 years (5.7), total bilirubin 0.7 mg/dL (0.3), creatinine 0.8 mg/dL (0.2), and body mass index 28.4 kg/m(2) (6.5). Low BMD was observed in 42 %: 30 % had osteopenia, 12 % had osteoporosis. Elevated tumor necrosis factor α, interleukin-6, and C-reactive protein levels were found in 26, 32, and 5 %, respectively, but did not differ by BMD group (p > 0.05). Patients with low BMD had higher serum phosphorus (4.1 vs. 3.5 mg/dL) and pro-peptide of type 1 collagen (P1NP; 73.1 vs. 47.5 ng/mL) [p < 0.05], but similar bone-specific alkaline phosphatase, serum C-telopeptide, and parathyroid hormone levels. Low BMD is prevalent in 40- to 60-year-old non-cirrhotics with chronic HCV, but not associated with systemic inflammatory markers. Elevated P1NP levels may help to identify those at increased risk of bone complications in this population. Chronic HCV should be considered a risk factor for bone loss, prompting earlier BMD assessments in both men and women.

A case of non-familial hemophagocytic lymphohistiocytosis (HLH) is described. The patient had a chronic course being alive and doing relatively well 3 years since onset. The specific pathological features of this disorder are discussed with emphasis on the fact that a remarkable loss of lymph node structure is sustained by a mature lymphohistiocytic infiltrate. Erythrophagocytosis is assessed as an important but not specific finding. Lymphocyte depletion is an important feature of the lesion. The presence of overlapping features in HLH, infection-associated hemophagocytic syndrome (IAHS) and X-linked recessive lymphoproliferative syndrome (XLS) is emphasized.

In the vaginal washings of 100 women with symptomatic non-specific vaginitis a succinate/lactate ratio of greater than or equal to 0.4 had a diagnostic sensitivity of 80%, a specificity of 83% for this condition. The predictive value of a positive test was 94%, but that of a negative test was only 55%. A strong association between the presence of Gardnerella vaginalis, anaerobes, a vaginal pH of above 4.5, and amines was found not only in non-specific vaginitis, but also in trichomonal and gonococcal infection. A variety of primary changes may encourage the multiplication of both gardnerellae and anaerobes and their presence in non-specific vaginitis may be a secondary rather than a primary event.

For thousands of years, opioids have been used to treat pain, and they continue to be one of the most commonly prescribed medications for pain. It is estimated that 90% of patients presenting to pain centers and receiving treatment in such facilities are on opioids. Opioids can be considered broad-spectrum analgesics that act at multiple points along the pain pathway. Unfortunately, opioids also have the potential for great harm, with multiple side effects and potential complications, some of which are lethal. They are also uniquely addictive, which can lead to misuse and diversion. We reviewed the relevant English literature and did thorough manual searches of the bibliographies of known primary and review articles. We utilized pain relief as the primary outcome measure. Other outcome measures were functional improvement, improvement of psychological status, improvement in work status, and evidence of addiction. Short-term use and improvement was defined as less than 6 months and long-term relief was defined as 6 months or longer. The 3 systematic reviews evaluating long-term effectiveness of opioids for chronic non-cancer pain provided unclear and weak evidence. The results of this review showed that many patients in the included studies were dissatisfied with adverse events or insufficient pain relief from opioids and withdrew from the studies. For patients able to continue on opioids, evidence was weak suggesting that their pain scores were lower than before therapy and that this relief could be maintained long-term (> 6 months). There was also weak evidence that long-term opioid therapy with morphine and transdermal fentanyl not only decreases pain but also improves functioning. Limited evidence was available for the most commonly used opioids, oxycodone and hydrocodone. Evidence for the ability to drive on chronic opioid therapy was moderate without major side effects or complications. It is concluded that, for long-term opioid therapy of 6 months or longer in managing chronic non-cancer pain, with improvement in function and reduction in pain, there is weak evidence for morphine and transdermal fentanyl. However, there is limited or lack of evidence for all other controlled substances, including the most commonly used drugs, oxycodone and hydrocodone.

Many biochemical, physiological and histological criteria have been used as indicators of exposures and effects of the contaminants. These changes can indicate the response of an organism to a specific environmental stressor. In the present paper, the effect of the acute and chronic exposure to cadmium as well as recovery from two cadmium concentrations (10 and 30 μgCd/g dry food) on gypsy moth (Lymantria dispar) midgut esterases was investigated. The influence of cadmium on trait plasticity was also examined. Esterases showed great sensitivity to low metal concentrations during acute and chronic treatments. Their activities during short-term exposure and after recovery significantly depended on cadmium concentrations. The esterases had greater index of plasticity during chronic treatments with 10 and 30 μgCd/dry food. Five esterase isoforms between 64 and 250 kDa were detected. Isoforms of esterases exposed to any of the two cadmium effects differed among several egg-masses. Isozymes were distinguished in one egg-mass during different cadmium treatments. We conclude that these enzymes could be considered potential and sensitive non-selective biomarkers for the presence of cadmium in food.

Face processing in chronic alcoholism: a specific deficit for emotional features.

Maurage, P; Campanella, S; Philippot, P; Martin, S; de Timary, P

2008-04-01

It is well established that chronic alcoholism is associated with a deficit in the decoding of emotional facial expression (EFE). Nevertheless, it is still unclear whether this deficit is specifically for emotions or due to a more general impairment in visual or facial processing. This study was designed to clarify this issue using multiple control tasks and the subtraction method. Eighteen patients suffering from chronic alcoholism and 18 matched healthy control subjects were asked to perform several tasks evaluating (1) Basic visuo-spatial and facial identity processing; (2) Simple reaction times; (3) Complex facial features identification (namely age, emotion, gender, and race). Accuracy and reaction times were recorded. Alcoholic patients had a preserved performance for visuo-spatial and facial identity processing, but their performance was impaired for visuo-motor abilities and for the detection of complex facial aspects. More importantly, the subtraction method showed that alcoholism is associated with a specific EFE decoding deficit, still present when visuo-motor slowing down is controlled for. These results offer a post hoc confirmation of earlier data showing an EFE decoding deficit in alcoholism by strongly suggesting a specificity of this deficit for emotions. This may have implications for clinical situations, where emotional impairments are frequently observed among alcoholic subjects.

Among the wide range of therapeutic alternatives proposed for the management of low-back pain (LBP), a less widely used technique from Spain, called neuroreflexotherapy (NRT) has claimed to show very favourable results, mainly in patients with chronic low-back pain. The aim of this review was to systematically assess the effectiveness of NRT for the treatment of non-specific LBP in adult patients, aged 16 to 65 years. A secondary objective was to compare NRT with other conventional interventions. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE to October 1, 2002. Only randomised controlled trials (RCTs) of NRT for the treatment of patients with a clinical diagnosis of non-specific LBP were included. Two reviewers independently selected trials and extracted data using pre-designed forms. Because the outcome variables were not assessed in a homogenous way, it was not possible to pool the results to obtain an estimate of global effect, as initially planned. Three RCT were included, with a total of 125 subjects randomised to the control groups and 148 subjects receiving active NRT. Neuroreflexotherapy was the same in all three trials, while the control groups received sham-NRT in two trials and standard care in one. Two trials studied patients with chronic LBP, the third studied patients with a mix of chronic and sub-acute LBP. Clinical outcomes were measured in the short-term (15 to 60 days) in all three trials; in one trial, resource utilization was measured after one year. Individuals who received active NRT showed statistically significantly better outcomes than the control groups for measures of pain, degree of mobility, disability, medication use, consumption of resources and costs. No significant differences were observed for quality of life measures. Side effects were more frequently reported in the control groups during short-term follow-up, with no major side effects reported by those receiving active NRT. NRT appears to be a safe and effective intervention for the treatment of chronic non-specific LBP. The efficacy is less clear for sub-acute LBP. However, these results are limited to three trials conducted by a small number of specifically trained and experienced clinicians, in a limited geographical location. No data are available on the ease and time-frame needed to achieve that level of expertise. RCTs by other practitioners, in other locations, that replicate the effects reported in this review are needed before recommending a broader practice.

Chronic fatigue syndrome defies the mind-body-schism of medicine. New perspectives on a multiple realisable developmental systems disorder.

PubMed

Ulvestad, Elling

2008-09-01

The article maintains that chronic fatigue syndrome can be properly understood only by taking an integrated perspective in which evolutionary, developmental and ecological aspects are considered. The integrative approach, supplemented by a complexity theory and psychoneuroimmunological research, is capable of explaining why there are so few structural aberrations to be found in chronic fatigue syndrome and why specific treatment is so difficult to establish. A major outcome of the investigation, that all individuals with chronic fatigue syndrome are diseased in their own way, emphasises the need to study the development of personalised life histories. It also highlights an ethical dimension; personalised disease defies essentialist thinking on patient management. Another major outcome, which follows from the developmental systems perspective, is the dissolution of ontological mind-body dualism. This in turn allows for a methodological complementation of the biological and phenomenological approaches to knowledge. New research strategies that may help to resolve chronic fatigue syndrome, grounded in the revised perspective on individual development, are suggested.

Pharmacist's role in dispensing opioids for acute and chronic pain.

Marlowe, Karen F; Geiler, Richard

2012-10-01

Pain continues to be a serious health care concern in the United States. Patients with chronic pain experience the impact of the disease throughout their lives including their social interactions, family relationships, and in many cases economic productivity. Multiple surveys have found that many pharmacists hold misconceptions regarding opioids, pain disease states, and their understandings of current regulations. Multiple barriers affect the ability of pharmacists to deliver care to patients' prescribed opioid therapy. Inadequate communication between health care professionals and patients is one of the hurdles, which prevents quality care. Increased communication between health care providers including access to health information is one step, which is crucial to improving provision of pharmacotherapy. Finally, the quality of educational opportunities relative to opioids and pain management specifically for pharmacists needs to be increased, and consideration needs to be given for making appropriate pain management education mandatory.

Evolution in quality of life and epidemiological impact after endovascular treatment of chronic cerebro-spinal venous insufficiency in patients with multiple sclerosis.

We report the outcome of 67 patients after endovascular treatment of chronic cerebro-spinal venous insufficiency in patients with multiple sclerosis. Material and methods For evaluating outcome, patients were divided into three groups with respective outcome after three, six and twelve months. Assessment of outcome was done by a disease-specific quality-of-life score that reflects the physical health (physical health composite, PHC) and mental health (mental health composite, MHC) by a score. Improvement in PHC was significant (P < 0.05) in the three- and six-month groups. Improvement in MHC was only significant (P < 0.05) in the three-month group. In conclusion, we can state that the result of endovascular treatment seems to decay although the baseline is still higher than preoperative. To confirm this finding, this study needs to be reproduced in a larger patient population.

Background and Purpose Although the motor deficit following stroke is clearly due to the structural brain damage that has been sustained, this relationship is attenuated from the acute to chronic phases. We investigated the possibility that motor impairment and response to Constraint-Induced Movement therapy (CI therapy) in chronic stroke patients may relate more strongly to the structural integrity of brain structures remote from the lesion than to measures of overt tissue damage. Methods Voxel-based morphometry (VBM) analysis was performed on MRI scans from 80 chronic stroke patients to investigate whether variations in grey matter density were correlated with extent of residual motor impairment or with CI therapy-induced motor recovery. Results Decreased grey matter density in non-infarcted motor regions was significantly correlated with magnitude of residual motor deficit. In addition, reduced grey matter density in multiple remote brain regions predicted a lesser extent of motor improvement from CI therapy. Conclusions Atrophy in seemingly healthy parts of the brain that are distant from the infarct accounts for at least a portion of the sustained motor deficit in chronic stroke. PMID:22096036

HIV-1 infected viremic controllers maintain durable viral suppression below 2000 copies viral RNA/ml without anti-retroviral therapy (ART), and the immunological factor(s) associated with host control in presence of low but detectable viral replication are of considerable interest. Here, we utilized a multivariable analysis to identify which innate and adaptive immune parameters best correlated with viral control utilizing a cohort of viremic controllers (median 704 viral RNA/ml) and non-controllers (median 21,932 viral RNA/ml) that were matched for similar CD4+ T cell counts in the absence of ART. We observed that HIV-1 Gag-specific CD8+ T cell responses were preferentially targeted over Pol-specific responses in viremic controllers (p = 0.0137), while Pol-specific responses were positively associated with viral load (rho = 0.7753, p = 0.0001, n = 23). Viremic controllers exhibited significantly higher NK and plasmacytoid dendritic cells (pDC) frequency as well as retained expression of the NK CD16 receptor and strong target cell-induced NK cell IFN-gamma production compared to non-controllers (p<0.05). Despite differences in innate and adaptive immune function however, both viremic controllers (p<0.05) and non-controller subjects (p<0.001) exhibited significantly increased CD8+ T cell activation and spontaneous NK cell degranulation compared to uninfected donors. Overall, we identified that a combination of innate (pDC frequency) and adaptive (Pol-specific CD8+ T cell responses) immune parameters best predicted viral load (R2 = 0.5864, p = 0.0021, n = 17) by a multivariable analysis. Together, this data indicates that preferential Gag-specific over Pol-specific CD8+ T cell responses along with a retention of functional innate subsets best predict host control over viral replication in HIV-1 infected viremic controllers compared to chronically-infected non-controllers.

Medication beliefs of patients with a specific medical condition have been associated with nonadherence to drugs used to treat that condition. However, associations between medication beliefs and nonadherence of individuals on chronic, multiple medications have not been studied. To investigate associations between patients' medication beliefs and nonadherence to chronic drug therapy. A cross-sectional, self-administered survey of patients waiting to see pharmacists at an outpatient pharmacy in a primary care clinic was conducted. Participants' medication beliefs were assessed using the Beliefs about Medicines Questionnaire, and nonadherence was assessed using the Morisky Medication Adherence Scale. Pearson correlation analysis was used to assess bivariate associations between medication beliefs and nonadherence. Regression was used to assess relative strength of associations between various medication beliefs and nonadherence and also to assess the significance of the interactions between those beliefs and nonadherence. There were positive bivariate associations between specific concerns about medications (p < 0.001), perceived general harmful effects of medications (p < 0.001), and perceived overprescribing of medications by physicians (p < 0.001) and medication nonadherence. When relative strength of associations between each medication belief and nonadherence was assessed, while controlling for other medication beliefs, specific-necessity (p = 0.02) and specific-concerns (p = 0.01) exhibited significant negative and positive associations with nonadherence, respectively. All two-way interactions between variables in the model were insignificant. A model consisting of age, total number of drugs used, and medication beliefs, that is, specific-necessity, specific-concerns, general-overuse, and general-harm, accounted for 26.5% of variance. Medication beliefs alone explained 22.4% of variation in nonadherence to chronic drug therapy. Patients' medication beliefs explained a significant portion of variation in medication nonadherence.

Purpose We report data from the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) network to: (1) identify participants having either (a) urologic chronic pelvic pain syndromes (UCPPS) only or (b) chronic functional non-urological associated somatic syndromes (NUAS) in addition to UCPPS, (2) characterize these two subgroups, and (3) explore these two subgroups using three criteria: (a) the MAPP eligibility criteria, (b) self-reported medical history, or (c) RAND interstitial cystitis epidemiologic (RICE) criteria. Materials and Methods Self-reported cross-sectional data were collected from men and women with UCPPS including: predominant symptoms, symptom duration and severity, NUAS symptoms, and psychosocial factors. Results Of 424 UCPPS participants, 162 (38%) had NUAS: 93 (22%) irritable bowel syndrome, 15 (4%) fibromyalgia, 13 (3%) chronic fatigue syndrome, and 41 (10%) with multiple syndromes. Among 233 females, 103 (44%) had NUAS compared to 59 (31%) of 191 males (p = 0.006). Participants with NUAS had more severe urological symptoms, and more frequent depression and anxiety. Of 424 participants, 228 (54%) met RICE criteria. Among 228 RICE-positive participants, 108 (47%) had NUAS compared to 54 (28%) of 203 RICE-negative patients with NUAS (p < 0.001). Conclusions NUAS represent important clinical characteristics of UCPPS. Participants with NUAS have more severe symptoms, longer duration and higher rates of depression and anxiety. RICE-positive patients are more likely to have NUAS and more severe symptoms. Because NUAS are more common in women, future studies need to account for this potential confounding factor in UCPPS.

Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and the leading cause of chronic liver disease in the Western world. Twenty percent of NAFLD individuals develop chronic hepatic inflammation (non-alcoholic steatohepatitis, NASH) associated with cirrhosis, portal hypertension and hepatocellular carcinoma, yet causes of progression from NAFLD to NASH remain obscure. Here, we show that the NLRP6 and NLRP3 inflammasomes and the effector protein IL-18 negatively regulate NAFLD/NASH progression, as well as multiple aspects of metabolic syndrome via modulation of the gut microbiota. Different animal models reveal that inflammasome deficiency-associated changes in the configuration of the gut microbiota are associated with exacerbated hepatic steatosis and inflammation through influx of TLR4 and TLR9 agonists into the portal circulation, leading to enhanced hepatic TNF-α expression that drives NASH progression. Furthermore, co-housing of inflammasome-deficient animals to wild type mice results in exacerbation of hepatic steatosis, glucose intolerance, and obesity. Thus, altered interactions between the gut microbiota and the host, produced by defective NLRP3 and NLRP6 inflammasome sensing, may govern the rate of progression of multiple metabolic syndrome-associated abnormalities, highlighting the central role of the microbiota in the pathogenesis of heretofore seemingly unrelated systemic auto-inflammatory and metabolic disorders.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Age and smoking are common risk factors for COPD and other illnesses, often leading COPD patients to demonstrate multiple coexisting comorbidities. COPD exacerbations and comorbidities contribute to the overall severity in individual patients. Clinical trials investigating the treatment of COPD routinely exclude patients with multiple comorbidities or advanced age. Clinical practice guidelines for a specific disease do not usually address comorbidities in their recommendations. However, the management and the medical intervention in COPD patients with comorbidities need a holistic approach that is not clearly established worldwide. This holistic approach should include the specific burden of each comorbidity in the COPD severity classification scale. Further, the pharmacological and nonpharmacological management should also include optimal interventions and risk factor modifications simultaneously for all diseases. All health care specialists in COPD management need to work together with professionals specialized in the management of the other major chronic diseases in order to provide a multidisciplinary approach to COPD patients with multiple diseases. In this review, we focus on the major comorbidities that affect COPD patients. We present an overview of the problems faced, the reasons and risk factors for the most commonly encountered comorbidities, and the burden on health care costs. We also provide a rationale for approaching the therapeutic options of the COPD patient afflicted by comorbidity. PMID:25609943

Immunohistochemical stains have been used for the distinction of pancreatic adenocarcinoma from chronic pancreatitis. To determine if a double stain for MUC/p53 improved specificity and sensitivity for distinction of pancreatic adenocarcinoma from chronic pancreatitis by comparing maspin, mucin 4 (MUC4), p53, Smad4, and the double stain MUC4/p53. Seventy-four pancreatic adenocarcinomas and 19 chronic pancreatitis cases were retrieved from archival files. Tissue cores were arrayed to create a tissue microarray of 2-mm cores. Sections were stained with antibodies against maspin, MUC4, p53, and Smad4. Additionally, a 2-color, double stain for MUC4 and p53 was developed and evaluated. Five percent or greater staining in either of the cores was considered positive. Intensity (0, 1, 2) and extent (%) of tumor cells staining was also determined. The sensitivity for distinction of pancreatic adenocarcinoma from chronic pancreatitis with maspin, MUC4, p53, and Smad4 was 90%, 77%, 60%, and 63%, respectively; the specificity was 67%, 78%, 88%, and 88%, respectively. When MUC4 and p53 were combined in a double stain, and positive staining for either considered a positive result, the sensitivity increased to 96% but specificity was 73%. When immunoreactivity for both antibodies was necessary for a positive result, sensitivity fell to 39% but specificity was 100%. No correlation was found between intensity or extent of staining with any of the individual stains and tumor differentiation. The double immunohistochemical stain for MUC4/p53 can be a useful diagnostic tool in conjunction with the hematoxylin-eosin-stained section for pancreatic adenocarcinoma, particularly when limited tumor is available for multiple stains.

Pay for performance (P4P) has been used as a strategy to improve quality for patients with chronic illness. Little was known whether care provided to individuals with multiple chronic conditions in a P4P program were cost-effective. This study investigated cost effectiveness of a diabetes P4P program for caring patients with diabetes alone (DM alone) and diabetes with comorbid hypertension and hyperlipidemia (DMHH) from a single payer perspective in Taiwan. Analyzing data using population-based longitudinal databases, we compared costs and effectiveness between P4P and non-P4P diabetes patient groups in two cohorts. Propensity score matching (PSM) was used to match comparable control groups for intervention groups. Outcomes included life-years, quality-adjusted life-years (QALYs), program intervention costs, cost-savings and incremental cost-effectiveness ratios (ICERs). QALYs for P4P patients and non-P4P patients were 2.80 and 2.71 for the DM alone cohort and 2.74 and 2.66 for the DMHH patient cohort. The average incremental intervention costs per QALYs was TWD$167,251 in the DM alone cohort and TWD$145,474 in the DMHH cohort. The average incremental all-cause medical costs saved by the P4P program per QALYs were TWD$434,815 in DM alone cohort and TWD$506,199 in the DMHH cohort. The findings indicated that the P4P program for both cohorts were cost-effective and the resulting return on investment (ROI) was 2.60:1 in the DM alone cohort and 3.48:1 in the DMHH cohort. We conclude that the diabetes P4P program in both cohorts enabled the long-term cost-effective use of resources and cost-savings, especially for patients with multiple comorbid conditions.

The average incremental all-cause medical costs saved by the P4P program per QALYs were TWD$434,815 in DM alone cohort and TWD$506,199 in the DMHH cohort. The findings indicated that the P4P program for both cohorts were cost-effective and the resulting return on investment (ROI) was 2.60:1 in the DM alone cohort and 3.48:1 in the DMHH cohort. We conclude that the diabetes P4P program in both cohorts enabled the long-term cost-effective use of resources and cost-savings, especially for patients with multiple comorbid conditions.

Abstract Transitional care management is effective at reducing hospital readmissions among patients with multiple chronic conditions, but evidence is lacking on the relative benefit of the home visit as a component of transitional care. The sample included non-dual Medicaid recipients with multiple chronic conditions enrolled in Community Care of North Carolina (CCNC), with a hospital discharge between July 2010 and December 2012. Using claims data and care management records, this study retrospectively examined whether home visits reduced the odds of 30-day readmission compared to less intensive transitional care support, using multivariate logistic regression to control for demographic and clinical characteristics. Additionally, the researchers examined group differences within clinical risk strata on inpatient admissions and total cost of care in the 6 months following hospital discharge. Of 35,174 discharges receiving transitional care from a CCNC care manager, 21% (N = 7468) included a home visit. In multivariate analysis, home visits significantly reduced the odds of readmission within 30 days (odds ratio = 0.52, 95% confidence interval 0.48–0.57). At the 6-month follow-up, home visits were associated with fewer inpatient admissions within 4 of 6 clinical risk strata, and lower total costs of care for highest risk patients (average per member per month cost difference $970; P < 0.01). For complex chronic patients, home visits reduced the likelihood of a 30-day readmission by almost half compared to less intensive forms of nurse-led transitional care support. Higher risk patients experienced the greatest benefit in terms of number of inpatient admissions and total cost of care in the 6 months following discharge.

Inflammation promotes amyloidogenesis in animals and markers of inflammation are associated with β-amyloid (Aβ) in humans. Hence, we sought to examine the cross-sectional associations between chronically elevated plasma C reactive protein (CRP) and cortical Aβ in 259 non-demented elderly individuals reporting subjective memory complaints from the Multidomain Alzheimer Preventive Trial (MAPT). Cortical-to-cerebellar standard uptake value ratios were obtained using [ 18 F] florbetapir positron emission tomography (PET). CRP was measured in plasma using immunoturbidity. Chronically raised CRP was defined as having 2 consecutively high CRP readings (>3 mg/l ≤ 10 mg/l) between study baseline and the 1 year visit (visits were performed at baseline, 6 months, 1 year and then annually). Associations were explored using adjusted multiple linear regression. Chronically raised CRP was found to be inversely associated with cortical Aβ (B-coefficient: -0.054, SE: 0.026, p = 0.040) and this association seemed to be specific to apolipoprotein E (Apo E) ε4 carriers (B-coefficient: -0.130, SE: 0.058, p = 0.027). CRP as an isolated reading measured closest to PET scan was also inversely associated with cortical Aβ when CRP was treated as a dichotomized variable (high CRP > 3 mg/l ≤ 10 mg/l, B-coefficient: -0.048, SE: 0.023, p = 0.043). Our preliminary findings suggest that inflammation might be beneficial in the early stages of Alzheimer's disease as the immune systems attempts to combat Aβ pathology particularly in ApoE ε4 carriers. Investigating the temporal relationships between cerebral Aβ and a panel of inflammatory markers would provide further evidence as to whether chronic inflammation might modulate amyloidogenesis in vivo.

Depressive patients with chronic heart failure (CHF) show less social integration and greater physical impairment as well as poorer compliance than non depressive CHF patients. Using multiple regression analyses, this study (n=84) investigated a potential mediating effect of depression on the relationship between compliance and both social support and physical functioning. Results did not support the hypothesized mediating effect of depression. However, the variables age, depression, left ventricular ejection fraction (LVEF) and social support were associated with self-reported compliance. Therefore, a lack of social support and depression should be considered as possible reasons, if patients are noncompliant during the treatment process. © Georg Thieme Verlag KG Stuttgart · New York.

Both dispositional optimism and illness representations are related to psychological health in chronic patients. In a group of chronic tinnitus sufferers, the interplay between these two variables was examined. Specifically, it was tested to what extent the relationship between dispositional optimism and depression is mediated by more positive illness representations. The study had a cross-sectional design. One hundred and eighteen patients diagnosed with chronic tinnitus completed questionnaires assessing optimism (Life Orientation Test-Revised [LOT-R]), illness representations (Illness Perceptions Questionnaire-Revised [IPQ-R]) and depression (Hospital Anxiety and Depression Scale [HADS]). Correlation analysis showed that optimism was associated with more positive illness representations and lower levels of depression. Simple mediation analyses revealed that the relationship between optimism and depression was partially mediated by the illness representation dimensions consequences, treatment control, coherence, emotional representations and internal causes. A multiple mediation analysis indicated that the total mediation effect of illness representations is particularly due to the dimension consequences. Optimism influences depression in tinnitus patients both directly and indirectly. The indirect effect indicates that optimism is associated with more positive tinnitus-specific illness representations which, in turn, are related to less depression. These findings contribute to a better understanding of the interplay between generalised expectancies, illness-specific perceptions and psychological adjustment to medical conditions.

Oral candidiasis (OC) is a common opportunistic infection in immunocompromised patients. Species identification is sometimes important for treatment. objective: to determine the prevalence of different Candida species colonising or infecting the oral mucosa (OM) of diabetic (DM) and non-diabetic (non-DM) chronic kidney disease patients, comparing both groups and exploring potential risk factors. 56 DM and 80 non-DM patients on chronic dialysis were examined. OM swabs were cultured on Sabouraud dextrose agar plates. Candida species were identified with API® galleries. OC was confirmed by exfoliative cytology. Statistical associations were analysed using χ2, Fisher's exact test (ET), and multiple logistic regression. Candida prevalence was 43.4%: 53.6% DM and 36.3% non-DM, (p=.045). The species identified were C. albicans 74.6%, C. glabrata 22.0%, C. tropicalis 15.2%, C. parapsilosis 3.4 %, C. kefyr 3.4% and C. famata 1.7% without difference between groups. DM patients had a higher xerostomia prevalence (p=.002) and lower salivary flow (p=.008) and lower serum albumin (p=.018). 16.9% of patients had OC, 23.2% DM compared with 12.5% non-DM, (p=.101). The following were associated with the presence of Candida in the OM: the use of dental prostheses (odds ratio [OR] 25.6, 95% confidence interval [CI] 2.5 to 253, P=.001), xerostomia (OR 9.6, 95% CI 2.4 to 38.1, P=.001) and low serum albumin values (OR 0.41, 95% CI 0.22 to 0.98, P=.044). The presence of Candida sp. in the OM was associated with dental prostheses, xerostomia and low serum albumin.

Signaling pathways targeted by curcumin in acute and chronic injury: burns and photo-damaged skin.

PubMed

Heng, Madalene C Y

2013-05-01

Phosphorylase kinase (PhK) is a unique enzyme in which the spatial arrangements of the specificity determinants can be manipulated to allow the enzyme to recognize substrates of different specificities. In this way, PhK is capable of transferring high energy phosphate bonds from ATP to serine/threonine and tyrosine moieties in serine/threonine kinases and tyrosine kinases, thus playing a key role in the activation of multiple signaling pathways. Phosphorylase kinase is released within five minutes following injury and is responsible for activating inflammatory pathways in injury-activated scarring following burns. In photo-damaged skin, PhK plays an important role in promoting photocarcinogenesis through activation of NF-kB-dependent signaling pathways with inhibition of apoptosis of photo-damaged cells, thus promoting the survival of precancerous cells and allowing for subsequent tumor transformation. Curcumin, the active ingredient in the spice, turmeric, is a selective and non-competitive PhK inhibitor. By inhibition of PhK, curcumin targets multiple PhK-dependent pathways, with salutary effects on a number of skin diseases induced by injury. In this paper, we show that curcumin gel produces rapid healing of burns, with little or no residual scarring. Curcumin gel is also beneficial in the repair of photo-damaged skin, including pigmentary changes, solar elastosis, thinning of the skin with telangiectasia (actinic poikiloderma), and premalignant lesions such as actinic keratoses, dysplastic nevi, and advanced solar lentigines, but the repair process takes many months. © 2012 The International Society of Dermatology.

Does core stability exercise improve lumbopelvic stability (through endurance tests) more than general exercise in chronic low back pain? A quasi-randomized controlled trial.

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.

To assess the prevalence of possible risk factors of upper gastrointestinal bleeding (UGIB) and their age-group specific trend among the general population and osteoarthritis patients. We utilized data from the National Health Insurance Service that included claims data and results of the national health check-up program. Comorbid conditions (peptic ulcer, diabetes, liver disease, chronic renal failure, and gastroesophageal reflux disease), concomitant drugs (aspirin, clopidogrel, cilostazol, non-steroidal anti-inflammatory drugs, steroid, anticoagulants, and SSRI), personal habits (smoking, and alcohol consumption) were considered as possible UGIB risk factors. We randomly imputed the prevalence of infection in the data considering the age-specific prevalence of Helicobacter pylori ( H. pylori ) infection in Korea. The prevalence of various UGIB risk factors and the age-group specific trend of the prevalence were identified. Prevalence was compared between osteoarthritis patients and others. A total of 801926 subjects (93855 osteoarthritis patients) aged 20 and above were included. The prevalence of individual and concurrent multiple risk factors became higher as the age increased. The prevalence of each comorbid condition and concomitant drug were higher in osteoarthritis patients. Thirty-five point zero two percent of the overall population and 68.50% of osteoarthritis patients had at least one or more risk factors of UGIB. The prevalence of individual and concurrent multiple risk factors in younger age groups were also substantial. Furthermore, when personal habits (smoking, and alcohol consumption) and H. pylori infection were included, the prevalence of concurrent multiple risk factors increased greatly even in younger age groups. Prevalence of UGIB risk factors was high in elderly population, but was also considerable in younger population. Patient with osteoarthritis was at higher UGIB risk than those without osteoarthritis. Physicians should consider individualized risk assessment regardless of age when prescribing drugs or performing procedures that may increase the risk of UGIB, and take necessary measures to reduce modifiable risk factors such as H. pylori eradication or lifestyle counseling.

Innate lymphoid cells in autoimmunity and chronic inflammatory diseases.

Abnormal activation of the innate immune system is a common feature of autoimmune and chronic inflammatory diseases. Since their identification as a separate family of leukocytes, innate lymphoid cells (ILCs) have emerged as important effector cells of the innate immune system. Alterations in ILC function and subtype distribution have been observed in a variety of immune-mediated diseases in humans and evidence from experimental models suggests a subtype specific role of ILCs in the pathophysiology of autoimmune inflammation. In this review, we discuss recent advances in the understanding of ILC biology in autoimmune and chronic inflammatory disorders, including multiple sclerosis, inflammatory bowel diseases, psoriasis, and rheumatic diseases, with a special focus on the potential of ILCs as therapeutic targets for the development of novel treatment strategies in humans.

Small intestinal bacterial overgrowth (SIBO) is a condition characterised by symptoms similar to pancreatic exocrine insufficiency (PEI) in chronic pancreatitis patients. SIBO is thought to complicate chronic pancreatitis in up to 92% of cases; however, studies are heterogeneous and protocols non-standardised. SIBO may be determined by measuring lung air-expiration of either hydrogen or methane which are by-products of small bowel bacterial fermentation of intraluminal substrates such as carbohydrates. We evaluated the prevalence of SIBO among a defined cohort of non-surgical chronic pancreatitics with mild to severe PEI compared with matched healthy controls. Thirty-five patients and 31 age-, gender- and smoking status-matched healthy controls were evaluated for SIBO by means of a fasting glucose hydrogen breath test (GHBT). The relationship between SIBO and clinical symptoms in chronic pancreatitis was evaluated. SIBO was present in 15% of chronic pancreatitis patients, while no healthy controls tested positive (P = 0.029). SIBO was more prevalent in those taking pancreatic enzyme replacement therapy (PERT) (P = 0.016), with proton pump inhibitor use (PPI) (P = 0.022) and in those with alcohol aetiology (P = 0.023). Patients with concurrent diabetes were more often SIBO-positive and this was statistically significant (P = 0.009). There were no statistically significant differences in reported symptoms between patients with and without SIBO, with the exception of 'weight loss', with patients reporting weight loss more likely to have SIBO (P = 0.047). The prevalence of SIBO in this study was almost 15% and consistent with other studies of SIBO in non-surgical chronic pancreatitis patients. These data support the testing of patients with clinically-relevant PEI unresolved by adequate doses of PERT, particularly in those patients with concurrent diabetes. SIBO can be easily diagnosed therefore allowing more specific and more targeted symptom treatment. Copyright © 2018. Published by Elsevier B.V.

Occupational-attributable chronic obstructive pulmonary disease (COPD) presents a substantial health challenge. Focusing on spirometric criteria for airflow obstruction, this review of occupational COPD includes both population-wide and industry-specific exposures. We used PubMed and Embase to identify relevant original epidemiological peer-reviewed articles, supplemented with citations identified from references in key review articles. This yielded 4528 citations. Articles were excluded for lack of lung function measurement, insufficient occupational exposure classification, lack of either external or internal referents, non-accounting of age or smoking effect, or major analytic inadequacies preventing interpretation of findings. A structured data extraction sheet was used for the remaining 147 articles. Final inclusion was based on a positive qualitative Scottish Intercollegiate Guidelines Network (SIGN) score (≥2+) for study quality, yielding 25 population-wide and 34 industry/occupation-specific studies, 15 on inorganic and 19 on organic dust exposure, respectively. There was a consistent and predominantly significant association between occupational exposures and COPD in 22 of 25 population-based studies, 12 of 15 studies with an inorganic/mineral dust exposure, and 17 of 19 studies on organic exposure, even though the studies varied in design, populations, and the use of measures of exposure and outcome. A nearly uniform pattern of a dose-response relationship between various exposures and COPD was found, adding to the evidence that occupational exposures from vapors, gas, dust, and fumes are risk factors for COPD. There is strong and consistent evidence to support a causal association between multiple categories of occupational exposure and COPD, both within and across industry groups.

Chronic stress accelerates the development of endometriosis in mouse through adrenergic receptor β2.

Does chronic stress in mice accelerate the development of endometriosis, and, if so, through what mechanism? Exposure to chronic stress accelerates the development of endometriosis and exacerbates the endometriosis-associated generalized hyperalgesia, most likely through activation of the adrenoceptor β2 (ADRB2) and cAMP responsive element-binding protein (CREB). Women with endometriosis tend to have higher levels of psychological stress, which is known to impact negatively on health in general and to promote tumor growth and metastasis in particular. Exposure to chronic stress before and after the induction of endometriosis is reported to increase lesion sizes in rodents, but it is unclear whether adrenoceptors are involved or not in the stress-promoted development of endometriosis. Three independent, prospective, randomized mouse experimentations. A total of 184 virgin female Balb/C mice were used. In Experiment 1, the mice were randomly divided into four groups: the control group, which received no stress; the before, after and both groups, which received immobilization stress before, after and both before and after the induction of endometriosis, respectively. In Experiment 2, mice were randomly divided into four groups one day after the induction of endometriosis: phosphate buffer saline (PBS) and propranolol (PROP) groups, which received the mini-pump containing, respectively, PBS only and propranolol (a non-selective ADRB antagonist) but no stress, STR+PROP and STR+PBS groups, which received stress and the mini-pump containing, respectively, propranolol and PBS. The immobilization stress started after the insertion of mini-pumps. In Experiment 3, mice were induced with endometriosis. Three days after the induction, they were randomly divided into four groups: control, ADRAa, ADRB2a, and ADRBa, which received the mini-pump containing solution only, metaraminol (a non-specific α adrenoceptor agonist), tebutaline (a specific ADRB2 agonist), or isoproterenol (a non-specific ADRB agonist), respectively. In all three experiments, the bodyweight and hotplate latency were evaluated before sacrifice 14 days after the induction. In all experimentations, the lesion weight was evaluated and the harvested ectopic endometrial tissue samples were subjected to immunohistochemistry analysis of vascular endothelial growth factor (VEGF), CD31-positive microvessels, proliferating cell nuclear antigen (PCNA), phosphorylated CREB, ADRB1, ADRB2, ADRB3, adrenergic receptor α1 (ADRA1) and ADRA2. Exposure to chronic stress accelerated the development of endometriosis and exacerbated the endometriosis-associated generalized hyperalgesia. This promotional effect is likely to be mediated through the systemic activation of the sympatho-adreno-medullary (SAM) axis, which results in subsequent release of catecholamines. The surging catecholamines may activate ADRB2 and CREB, yielding increased angiogenesis and cellular proliferation in ectopic endometrium in mice with induced endometriosis. In addition, β adrenergic receptor blockade completely abolished the promotional effect of chronic stress, likely through suppression of ADRB2 and CREB activation, thus suppressing angiogenesis and proliferation. Moreover, a non-specific adrenergic β agonist and a specific adrenergic β2 agonist, but not non-specific adrenergic α agonist, acted similarly to chronic stress, accelerating the development of endometriosis and exacerbating the generalized hyperalgesia in mice with pre-existing endometriosis. NA. This study is limited by the use of immunohistochemistry analyses only and the lack of molecular data. The present study provides the experimental evidence that chronic stress can promote the development of endometriosis through the activation of ADRB2. Given ADRB2 is also expressed in human endometriosis and appears to be functional, and in light of recent awareness that adrenergic signaling plays critical roles in tumorigenesis, it is likely that adrenergic signaling may play important roles in the development of endometriosis and is potentially a target for intervention.

The well-being of non-human primates in captivity is of joint concern to scientists, veterinarians, colony managers, caretakers, and researchers working with non-human primates in biomedical research. With increased regulatory, accreditation, and research focus on optimizing the use of social housing for laboratory primates, as well as the advent of techniques to assess indices of chronic stress and related measures of well-being, there is no better time to present the most current advances in the field of non-human primate behavioral management. The collective body of research presented here was inspired in part by a 2014 symposium entitled, "Chronic Hormones and Demographic Variables: Center-Wide Studies on Non-Human Primate Well-Being" held at the American Society of Primatologists' 37th Annual Meeting in Decatur, GA. By aiming to target readership with scientific and/or management oversight of captive primate behavioral management programs, this special issue provides badly-needed guidance for implementing social housing programs in a research environment and leverages collaboration across multiple facilities to address key components of behavioral management, explore refinements in how well-being can be measured, and identify the interrelationships between varying indices.

The authors report a case of fatal tuberculous meningoencephalitis following chronic bilateral otitis media in a child. Mycobacterium tuberculosis was identified in the CSF and in the otitis secretions. There were no pulmonary tuberculosis signs, thus the tuberculous otitis was considered as primary. In high tuberculosis endemic areas like Central African Republic it is important to consider tuberculosis, in chronic otitis media resistant to non specific therapy, and to reinforce the immunization programs for children.

Background Prior research has established health disparities between people with and without disabilities. However, disparities within the disability population, such as those related to type of disability, have been much less studied. Objective To examine differences in chronic conditions and health status between subgroups of people with different types of disability. Methods We analyzed Medical Expenditure Panel Survey annual data files from 2002-2008. Logistic regression analyses considered disparity from three perspectives: 1) basic differences, unadjusted for other factors; 2) controlling for key demographic and health covariates; and 3) controlling for a larger set of demographic variables and socioeconomic status as well as health and access to healthcare. Results Individuals with vision, physical, cognitive, or multiple disability types fared worse than people with hearing impairment on most health outcomes. This was most consistently true for people with multiple disabilities. Even when all covariates were accounted for, people with multiple types of disability were significantly more likely (p < 0.05) than those with hearing impairment (reference group) to report every poor health outcome with the exception of BMI ≥ 25 and lung disease. Conclusions While many of the differences between disability types were reduced when controlling for other factors, some differences remained significant. This argues for a more individualized approach to understanding and preventing chronic conditions and poor health in specific disability groups. PMID:24060250

To determine whether the multiple hop test should be used as an evaluative or a discriminative instrument for chronic ankle instability (CAI). Blinded case-control study. : University research laboratory. Twenty-nine healthy subjects (21 men, 8 women, mean age 21.8 years) and 29 patients with CAI (17 men, 12 women, mean age 24.9 years) were selected. Subjects performed a multiple hop test and hopped on 10 different tape markers while trying to avoid any postural correction. Minimal detectable changes (MDC) of the number of balance errors, the time value, and the visual analog scale (VAS) score (perceived difficulty) were calculated as evaluative measures. For the discriminative properties, a receiver operating characteristic curve was determined and the area under curve (AUC), the sensitivity, specificity, diagnostic accuracy (DA), and likelihood ratios (LR) were calculated whether 1, 2, or 3 outcomes were positive. Based on their MDC, outcomes should, respectively, change by more than 7 errors (41%), 6 seconds (15%), and 27 mm (55%, VAS score) before considering it as a real change. Area under curves were, respectively, 79% (errors), 77% (time value), and 65% (VAS score). The most optimal cutoff point was, respectively, 13.5 errors, 35 seconds, and 32.5 mm. When 2 of 3 outcomes were positive, the sensitivity was 86%, the specificity was 79%, the DA was 83%, the positive LR was 4.2, and the negative LR was 0.17. The multiple hop test seems to be more a discriminative instrument for CAI, and its responsiveness needs to be demonstrated.

Abstract Non-freezing cold injury develops after sustained exposure to cold temperatures, resulting in tissue cooling but not freezing. This can result in persistent sensory disturbance of the hands and feet including numbness, paraesthesia and chronic pain. Both vascular and neurological aetiologies of this pain have been suggested but remain unproven. We prospectively approached patients referred for clinical assessment of chronic pain following non-freezing cold injury between 12 February 2014 and 30 November 2016. Of 47 patients approached, 42 consented to undergo detailed neurological evaluations including: questionnaires to detail pain location and characteristics, structured neurological examination, quantitative sensory testing, nerve conduction studies and skin biopsy for intraepidermal nerve fibre assessment. Of the 42 study participants, all had experienced non-freezing cold injury while serving in the UK armed services and the majority were of African descent (76.2%) and male (95.2%). Many participants reported multiple exposures to cold. The median time between initial injury and referral was 3.72 years. Pain was principally localized to the hands and the feet, neuropathic in nature and in all study participants associated with cold hypersensitivity. Clinical examination and quantitative sensory testing were consistent with a sensory neuropathy. In all cases, large fibre nerve conduction studies were normal. The intraepidermal nerve fibre density was markedly reduced with 90.5% of participants having a count at or below the 0.05 centile of published normative controls. Using the Neuropathic Pain Special Interest Group of the International Association for the Study of Pain grading for neuropathic pain, 100% had probable and 95.2% definite neuropathic pain. Chronic non-freezing cold injury is a disabling neuropathic pain disorder due to a sensory neuropathy. Why some individuals develop an acute painful sensory neuropathy on sustained cold exposure is not yet known, but individuals of African descent appear vulnerable. Screening tools, such as the DN4 questionnaire, and treatment algorithms for neuropathic pain should now be used in the management of these patients. PMID:28969380

Cerebral Vascular Injury in Traumatic Brain Injury.

2016-01-01

Traumatic cerebral vascular injury (TCVI) is a very frequent, if not universal, feature after traumatic brain injury (TBI). It is likely responsible, at least in part, for functional deficits and TBI-related chronic disability. Because there are multiple pharmacologic and non-pharmacologic therapies that promote vascular health, TCVI is an attractive target for therapeutic intervention after TBI. The cerebral microvasculature is a component of the neurovascular unit (NVU) coupling neuronal metabolism with local cerebral blood flow. The NVU participates in the pathogenesis of TBI, either directly from physical trauma or as part of the cascade of secondary injury that occurs after TBI. Pathologically, there is extensive cerebral microvascular injury in humans and experimental animal, identified with either conventional light microscopy or ultrastructural examination. It is seen in acute and chronic TBI, and even described in chronic traumatic encephalopathy (CTE). Non-invasive, physiologic measures of cerebral microvascular function show dysfunction after TBI in humans and experimental animal models of TBI. These include imaging sequences (MRI-ASL), Transcranial Doppler (TCD), and Near InfraRed Spectroscopy (NIRS). Understanding the pathophysiology of TCVI, a relatively under-studied component of TBI, has promise for the development of novel therapies for TBI. Published by Elsevier Inc.

The role of self-management in designing care for people with osteoarthritis of the hip and knee.

PubMed

Brand, Caroline A

2008-11-17

Osteoarthritis of the hip and knee is an increasingly common condition that is managed principally with lifestyle behaviour changes. Osteoarthritis management can be complex, as it typically affects older patients with multiple comorbidities. There is evidence that opportunities exist to improve uptake of evidence-based recommendations for care, especially for non-pharmacological interventions. The National Chronic Disease Strategy (NCDS) defines key components of programs designed to meet the needs of people with chronic conditions; one component is patient self-management. NCDS principles have been effectively integrated into chronic disease management programs for other conditions, but there is limited evidence of effectiveness for osteoarthritis programs. A comprehensive osteoarthritis management model that reflects NCDS policy is needed. Barriers to implementing such a model include poor integration of decision support, a lack of national infrastructure, workforce constraints and limited funding.

A case-control study is the most powerful design to test the risk of specific congenital malformations associated with a specific drug. However, malformation registries often lack non-malformed controls. For the Dutch EUROCAT, we collected a non-malformed control group: the 'Healthy Pregnant'. The aim of this study was to evaluate the representativeness of this control group for the general pregnant population in the northern part of the Netherlands. The Healthy Pregnant data set includes data from two midwife practices. The baseline characteristics of mother and child including smoking status, drinking status, body mass index, maternal age, educational level, exposures to several drugs for chronic diseases and pregnancy related symptoms were evaluated. Compared with the general population, mothers in Healthy Pregnant group (n = 556) were from either low or high education level, were more likely to have a body mass index > 25 kg/m² (26% versus 22%, p = 0.08) or to smoke (19% versus 10%, p < 0.01) but were less likely to consume alcohol (20% versus 29%, p < 0.01). The use of drugs for chronic conditions was lower in Healthy Pregnant group. Furthermore, drugs for occasional use were prescribed less frequently, and a significant underreporting of children with a low birth weight and a short duration of gestation was found. The Healthy Pregnant data set was not representative of the general pregnant population in the northern part of the Netherlands. Specifically, the exposure to (chronic) drugs was underestimated, possibly a result of second-line care on the basis of medical indication. Thus, continuous investigation of options for improvement of the Healthy Pregnant database is required. Copyright © 2011 John Wiley & Sons, Ltd.

The aim of the proposed study is to analyze the effect of a six-week osteopathic visceral manipulation (OVM) program on the flexion-relaxation phenomenon in individuals with non-specific chronic low back pain (LBP) and functional constipation. An assessor-blinded, two-arm, randomized, placebo-controlled trial will be conducted. The sample will comprise 76 individuals with non-specific chronic LBP who have functional intestinal constipation, aged 18-65 years. The participants will be randomly allocated to two groups: (1) OVM and (2) sham OVM (SOVM). Evaluations will involve an interview, the Oswestry Disability Index, Fear-Avoidance Beliefs Questionnaire, functional constipation according to Rome III criteria, Biering-Sorensen test to normalize electromyographic (EMG) data, T12-L1 paraspinal level of the EMG signal during the flexion-relaxation phenomenon, 11-point numeric pain rating scale and fingertip-to-floor test. OVM and SOVM will be performed once per week for six weeks. Group 1 will receive OVM for 15 min and Group 2 will receive a sham visceral technique. Evaluations will be performed before and after the first session, after six weeks of treatment, and three months after randomization (follow-up). The findings will be analyzed statistically considering a 5% significance level (p ≤ 0.05). The limitation of the study is that the therapist will not be blinded. This will be the first trial to analyze the clinical response and electromyographic signals during the flexion-relaxation phenomenon after OVM. Brazilian Clinical Trial Registry, RBR-7sx8j3 .

HIV-1 often evades cytotoxic T cell (CTL) responses by generating variants that are not recognized by CTLs. We used single-genome amplification and sequencing of complete HIV genomes to identify longitudinal changes in the transmitted/founder virus from the establishment of infection to the viral set point at 1 year after the infection. We found that the rate of viral escape from CTL responses in a given patient decreases dramatically from acute infection to the viral set point. Using a novel mathematical model that tracks the dynamics of viral escape at multiple epitopes, we show that a number of factors could potentially contribute to a slower escape in the chronic phase of infection, such as a decreased magnitude of epitope-specific CTL responses, an increased fitness cost of escape mutations, or an increased diversity of the CTL response. In the model, an increase in the number of epitope-specific CTL responses can reduce the rate of viral escape from a given epitope-specific CTL response, particularly if CD8+ T cells compete for killing of infected cells or control virus replication nonlytically. Our mathematical framework of viral escape from multiple CTL responses can be used to predict the breadth and magnitude of HIV-specific CTL responses that need to be induced by vaccination to reduce (or even prevent) viral escape following HIV infection.

Objectives The objective of this study was to evaluate the problem of multiple chronic conditions and polypharmacy in patients with fibromyalgia. Design Retrospective medical record review. Setting Olmsted County, Minnesota. Participants 1111 adults with fibromyalgia. Primary and secondary outcome measures Number and type of chronic medical and psychiatric conditions, medication use. Results Medical record review demonstrated that greater than 50% of the sample had seven or more chronic conditions. Chronic joint pain/degenerative arthritis was the most frequent comorbidity (88.7%), followed by depression (75.1%), migraines/chronic headaches (62.4%) and anxiety (56.5%). Approximately, 40% of patients were taking three or more medications for symptoms of fibromyalgia. Sleep aids were the most commonly prescribed medications in our sample (33.3%) followed by selective serotonin reuptake inhibitors (28.7%), opioids (22.4%) and serotonin norepinephrine reuptake inhibitors (21.0%). Conclusions The results of our study highlight the problem of multiple chronic conditions and high prevalence of polypharmacy in fibromyalgia. Clinicians who care for patients with fibromyalgia should take into consideration the presence of multiple chronic conditions when recommending medications. PMID:25735301

The effectiveness of pharmacological therapies is dependent in part on patient persistency with the prescribed therapeutic regimen. In the case of non-specific non-steroidal anti-inflammatory drugs (NSAIDs), effectiveness is often compromised by undesirable side-effects, poor compliance or discontinuation of therapy. While patterns of utilization of non-specific NSAIDs have been investigated, few data are available on the patterns of persistency for cyclooxygenase (COX)-2-specific inhibitors. This study used a provincial health-care system database in Quebec, Canada, to determine the duration of treatment in new users of COX-2-specific inhibitors and non-specific NSAIDs over the first 3 months of treatment, and to characterize the factors associated with treatment persistency. Results demonstrate that the median duration of treatment was longer among patients initially prescribed COX-2-specific inhibitors (30 days and 23 days for celecoxib and rofecoxib respectively) than in those prescribed non-selective NSAIDs (10 days). Although the percentage of patients remaining on COX-2-specific drugs declined over the course of treatment, few patients on either celecoxib or rofecoxib switched drugs, either to the other COX-2-specific inhibitor or to non-specific NSAIDs. Factors associated with persistent drug use were: COX-2-specific inhibitors, age, and the use of gastroprotective agents either at treatment initiation or during follow-up. Dosage, chronic disease score and prescriber's specialty were only marginally associated with persistency. Prior use of gastroprotective agents was associated with lower persistency. Although the limitations of this study, which included lack of information on the indication for the prescription and the reason for switch or discontinuation, preclude definite conclusions regarding patterns of use of these drugs, the data suggest that the use of COX-2-specific inhibitors may result in increased persistency with treatment.

The chronic nature and associated complications of nonhealing wounds have led to the emergence of nanotechnology-based therapies that aim at facilitating the healing process and ultimately repairing the injured tissue. A number of engineered nanotechnologies have been proposed demonstrating unique properties and multiple functions that address specific problems associated with wound repair mechanisms. In this outlook, we highlight the most recently developed nanotechnology-based therapeutic agents and assess the viability and efficacy of each treatment, with emphasis on chronic cutaneous wounds. Herein we explore the unmet needs and future directions of current technologies, while discussing promising strategies that can advance the wound-healing field. PMID:28386594

Pharmacotherapy for chronic non-specific low back pain: current and future options.

Low back pain is associated with a large burden-of-illness. It is responsible for the most years lived with disability as compared with any other medical condition. A comprehensive overview of the evidence on pharmacological treatment options for chronic low back pain is lacking. This review evaluates the evidence for the benefits and risks of currently available pharmacological treatments for chronic low back pain. Areas covered: The authors focus on the recent (Cochrane) systematic reviews and meta-analyses of randomized clinical trials covering paracetamol (acetaminophen), NSAIDs, muscle relaxants, antidepressants, anticonvulsants, opioids, and other (new) drugs. Expert opinion: The overall impression of the efficacy of pharmacological treatments for patients with chronic low back pain is rather sobering. The effects on pain reduction and improvement of function are commonly small to moderate and short lasting when compared to placebo. At the same time, the various types of drugs are not without side-effects. This holds especially true for serious side-effects associated with (prolonged) use of strong opioids. Future studies on patients with chronic back pain should aim to identify subgroups of patients with good response to specific pharmacological treatment to facilitate personalized care.

Acid mediates a prolonged antinociception via substance P signaling in acid-induced chronic widespread pain.

Substance P is an important neuropeptide released from nociceptors to mediate pain signals. We recently revealed antinociceptive signaling by substance P in acid-sensing ion channel 3 (ASIC3)-expressing muscle nociceptors in a mouse model of acid-induced chronic widespread pain. However, methods to specifically trigger the substance P antinociception were still lacking. Here we show that acid could induce antinociceptive signaling via substance P release in muscle. We prevented the intramuscular acid-induced hyperalgesia by pharmacological inhibition of ASIC3 and transient receptor potential V1 (TRPV1). The antinociceptive effect of non-ASIC3, non-TRPV1 acid signaling lasted for 2 days. The non-ASIC3, non-TRPV1 acid antinociception was largely abolished in mice lacking substance P. Moreover, pretreatment with substance P in muscle mimicked the acid antinociceptive effect and prevented the hyperalgesia induced by next-day acid injection. Acid could mediate a prolonged antinociceptive signaling via the release of substance P from muscle afferent neurons in a non-ASIC3, non-TRPV1 manner.

Previous studies have demonstrated that early environmental interventions influence the consumption of palatable food and the abdominal fat deposition in female rats chronically exposed to a highly caloric diet in adulthood. In this study, we verified the metabolic effects of chronic exposure to a highly palatable diet, and determine the response to its withdrawal in adult neonatally handled and non-handled rats. Consumption of foods (standard lab chow and chocolate), body weight gain, abdominal fat deposition, plasma triglycerides, and leptin, as well as serum butyrylcholinesterase (BuChE), and cerebral acetylcholinesterase (AChE) activities were measured during chronic chocolate exposure and after deprivation of this palatable food in female rats exposed or not to neonatal handling (10 minutes/day, 10 first days of life). Handled rats increased rebound chocolate consumption in comparison to non-handled animals after 1 week of chocolate withdrawal; these animals also decreased body weight in the first 24 hours but this effect disappeared after 7 days of withdrawal. Chocolate increased abdominal fat in non-handled females, and this effect remained after 30 days of withdrawal; no differences in plasma leptin were seen after 7 days of withdrawal. Chocolate also increased serum BuChE activity in non-handled females, this effect was still evident after 7 days of withdrawal, but it disappeared after 30 days of withdrawal. Chocolate deprivation decreased cerebral AChE activity in both handled and non-handled animals. These findings suggest that neonatal handling modulates the preference for palatable food and induces a specific metabolic response that may be more adaptive in comparison to non-handled rats.

Alterations in the social and cognitive domain are considered important indicators for increased disability in many stress-related disorders. Similar impairments have been observed in rodents chronically exposed to stress, mimicking potential endophenotypes of stress-related psychopathologies such as major depression disorder (MDD), anxiety, conduct disorder, and posttraumatic stress disorder (PTSD). Data from numerous studies suggest that deficient plasticity mechanisms in hippocampus (HC) and prefrontal cortex (PFC) might underlie these social and cognitive deficits. Specifically, stress-induced deficiencies in neural plasticity have been associated with a hypodopaminergic state and reduced neural plasticity persistence. Here we assessed the effects of unpredictable chronic mild stress (UCMS) on exploratory, social and cognitive behavior of females of two inbred mouse strains (C57BL/6J and DBA/2J) that differ in their dopaminergic profile. Exposure to chronic stress resulted in impaired circadian rhythmicity, sociability and social cognition in both inbred strains, but differentially affected activity patterns and contextual discrimination performance. These stress-induced behavioral impairments were accompanied by reduced expression levels of brain derived neurotrophic factor (BDNF) in the prefrontal cortex. The strain-specific cognitive impairment was coexistent with enhanced plasma corticosterone levels and reduced expression of genes related to dopamine signaling in hippocampus. These results underline the importance of assessing different strains with multiple test batteries to elucidate the neural and genetic basis of social and cognitive impairments related to chronic stress.

Study protocol of cost-effectiveness and cost-utility of a biopsychosocial multidisciplinary intervention in the evolution of non-specific sub-acute low back pain in the working population: cluster randomised trial

PubMed Central

2011-01-01

Background Low back pain (LBP), with high incidence and prevalence rate, is one of the most common reasons to consult the health system and is responsible for a significant amount of sick leave, leading to high health and social costs. The objective of the study is to assess the cost-effectiveness and cost-utility analysis of a multidisciplinary biopsychosocial educational group intervention (MBEGI) of non-specific sub-acute LBP in comparison with the usual care in the working population recruited in primary healthcare centres. Methods/design The study design is a cost-effectiveness and cost-utility analysis of a MBEGI in comparison with the usual care of non-specific sub-acute LBP. Measures on effectiveness and costs of both interventions will be obtained from a cluster randomised controlled clinical trial carried out in 38 Catalan primary health care centres, enrolling 932 patients between 18 and 65 years old with a diagnosis of non-specific sub-acute LBP. Effectiveness measures are: pharmaceutical treatments, work sick leave (% and duration in days), Roland Morris disability, McGill pain intensity, Fear Avoidance Beliefs (FAB) and Golberg Questionnaires. Utility measures will be calculated from the SF-12. The analysis will be performed from a social perspective. The temporal horizon is at 3 months (change to chronic LBP) and 12 months (evaluate the outcomes at long term). Assessment of outcomes will be blinded and will follow the intention-to-treat principle. Discussion We hope to demonstrate the cost-effectiveness and cost-utility of MBEGI, see an improvement in the patients' quality of life, achieve a reduction in the duration of episodes and the chronicity of non-specific low back pain, and be able to report a decrease in the social costs. If the intervention is cost-effectiveness and cost-utility, it could be applied to Primary Health Care Centres. Trial registration ISRCTN: ISRCTN58719694 PMID:21859489

What Is the Prevalence of Symptomatic Obstructive Sleep Apnea Syndrome in Chronic Spinal Pain Patients? An Assessment of the Correlation of OSAS with Chronic Opioid Therapy, Obesity, and Smoking.

In modern medicine, obstructive sleep apnea syndrome (OSAS) is a commonly described sleep disorder with airway obstruction, disrupted sleep, and excessive daytime sleepiness. Since its description in 1976 by Guilleminault et al, numerous epidemiologic studies and systematic reviews, with multiple comorbidities related to cardiovascular sequelae, altered cognitive function, and multiple other potential complications have been described. Multiple risk factors have been identified included obesity, smoking, alcohol consumption, and other factors. Chronic pain and chronic opioid therapy also have been described to contribute to a large proportion of patients with OSAS. Chronic pain, obesity, smoking, and chronic opioid therapy are often found together, yet there is a paucity of literature describing OSAS in chronic pain patients. To assess the prevalence of symptomatic OSAS in chronic spinal pain patients receiving chronic opioid therapy and determine the association of OSAS with multiple risk factors and comorbidities. A retrospective assessment of patients who attend a single interventional pain management practice from January 1, 2010to December 31, 2014. A private interventional pain management practice in the United States. The data were collected from 4,036 consecutive patients presenting for assessment to a pain management center from January 1, 2010 to December 31, 2014. All assessments were comprehensive and performed by 2 physicians. The comprehensive assessment included a complete history, a physical examination, and a review of records. The prevalence of OSAS in patients with chronic spinal pain was 13.8%. The results showed a higher prevalence in males compared to females (15.1% versus 12.8%), a higher prevalence in those aged 45 or older compared to those 25-45 years and those 18-25 years (16.3% versus 10.7% or 2.5%), higher prevalence in Hispanics and Asians compared to African Americans and whites (23.7% versus 16.2% versus 13.4%), higher prevalence in patients with combined back and neck pain compared to patients with thoracic pain only or back pain only (16.3% versus 8.2% to 11%). Prevalence also varied by body mass index (BMI): 32.4% in morbidly obese patients, 20.3% in severely obese patients, 15.7% in obese patients, 9.2% in those who were overweight, and only 5.7% in those with normal weight. A significant correlation with OSAS was also observed in patients smoking more than 40 pack years and multiple respiratory symptoms except for chronic bronchitis and multiple cardiovascular ailments. The retrospective nature of the assessment. This retrospective assessment of over 4,000 patients suffering from chronic pain and receiving chronic opioid therapy indicated a prevalence of sleep apnea syndrome as 13.8%. Multiple risk factors including obesity, chronic obstructive pulmonary disease (COPD), chronic sinus and nasal discharge, and multiple comorbidities including cardiovascular and related ailments have been identified.

Prevalence of chronic musculoskeletal disorders in elderly Brazilians: a systematic review of the literature

PubMed Central

2012-01-01

Background Population ageing is a worldwide phenomenon that has recently challenged public healthcare systems. The knowledge of the burden of chronic musculoskeletal disorders in elders is still limited, particularly in the developing world. This systematic review aimed to investigate the prevalence of chronic musculoskeletal disorders in elderly Brazilians. Methods A comprehensive literature search was performed in five electronic databases (from inception to January 2012) and completed by additional searches in reference lists. Two review authors independently selected the eligible studies and extracted data on participants’ characteristics and rates of chronic musculoskeletal disorders. One review author extracted methodological quality data. We performed a critical synthesis of the results, which were grouped into the diagnoses “chronic musculoskeletal pain” or “specific musculoskeletal diagnoses”. Results Twenty five studies reporting on a total of 116,091 elderly Brazilians were included. Eight studies (32%) were of high methodological quality. There was a large variation in the measure of prevalence used by individual studies and in their definition of chronic pain. Prevalence estimates reached 86% for chronic musculoskeletal pain in any location. Studies investigating multiple pain sites found the lower limb and the spine to be the most prevalent complaints (50% each). Arthritis and rheumatism (including osteoarthritis) were the most prevalent specific musculoskeletal diagnoses (9% to 40%), followed by herniated disc (6% to 27%). Conclusions Despite the growth of the elderly population worldwide, high-quality research on the burden of chronic musculoskeletal disorders in the elderly is still scarce. Future healthcare research focusing on this age group should be a priority in developing countries since their public healthcare systems are not yet fully prepared to accommodate the needs of an aging population.

BACKGROUND: Participation bias in exercise studies is poorly understood among older adults. This study was aimed at looking into whether older persons who volunteer to participate in an exercise study differ from non-volunteers. METHODS: A self-reported questionnaire on physical activity and general health was mailed out to 1000 persons, aged 60 or over, who were covered by the medical insurance of the French National Education System. Among them, 535 answered it and sent it back. Two hundred and thirty-three persons (age 69.7 ±7.6, 65.7% women) said they would volunteer to participate in an exercise study and 270 (age 71.7 ±8.8, 62.2% women) did not. RESULTS: Volunteers were younger and more educated than non-volunteers, but they did not differ in sex. They had less physical function decline and higher volumes of physical activity than non-volunteers. Compared to volunteers, non-volunteers had a worse self-reported health and suffered more frequently from chronic pain. Multiple logistic regressions showed that good self-reported health, absence of chronic pain, and lower levels of physical function decline were associated with volunteering to participate in an exercise study. CONCLUSIONS: Volunteers were fitter and healthier than non-volunteers. Therefore, caution must be taken when generalizing the results of exercise intervention studies.

Major depressive disorder (MDD), schizophrenia (SCH), Alzheimer's disease (AD), and Parkinson's disease (PD) are devastating neurological disorders, which increasingly contribute to global morbidity and mortality. Although the pathogenic mechanisms of these conditions are quite diverse, chronic neuroinflammation is one underlying feature shared by all these diseases. Even though the specific root causes of these diseases remain to be identified, evidence indicates that the observed neuroinflammation is initiated by unique pathological features associated with each specific disease. If the initial acute inflammation is not resolved, a chronic neuroinflammatory state develops and ultimately contributes to disease progression. Chronic neuroinflammation is characterized by adverse and non-specific activation of glial cells, which can lead to collateral damage of nearby neurons and other glia. This misdirected neuroinflammatory response is hypothesized to contribute to neuropathology in MDD, SCH, AD, and PD. Physical activity (PA), which is critical for maintenance of whole body and brain health, may also beneficially modify neuroimmune responses. Since PA has neuroimmune-modifying properties, and the common underlying feature of MDD, SCH, AD, and PD is chronic neuroinflammation, we hypothesize that PA could minimize brain diseases by modifying glia-mediated neuroinflammation. This review highlights current evidence supporting the disease-altering potential of PA and exercise through modifications of neuroimmune responses, specifically in MDD, SCH, AD and PD.

S-RNase-based gametophytic self-incompatibility evolved once before the split of the Asteridae and Rosidae. In Prunus (tribe Amygdaloideae of Rosaceae), the self-incompatibility S-pollen is a single F-box gene that presents the expected evolutionary signatures. In Malus and Pyrus (subtribe Pyrinae of Rosaceae), however, clusters of F-box genes (called SFBBs) have been described that are expressed in pollen only and are linked to the S-RNase gene. Although polymorphic, SFBB genes present levels of diversity lower than those of the S-RNase gene. They have been suggested as putative S-pollen genes, in a system of non-self recognition by multiple factors. Subsets of allelic products of the different SFBB genes interact with non-self S-RNases, marking them for degradation, and allowing compatible pollinations. This study performed a detailed characterization of SFBB genes in Sorbus aucuparia (Pyrinae) to address three predictions of the non-self recognition by multiple factors model. As predicted, the number of SFBB genes was large to account for the many S-RNase specificities. Secondly, like the S-RNase gene, the SFBB genes were old. Thirdly, amino acids under positive selection-those that could be involved in specificity determination-were identified when intra-haplotype SFBB genes were analysed using codon models. Overall, the findings reported here support the non-self recognition by multiple factors model.

Multiple sclerosis (MS) is a chronic demyelinating disorder of unknown etiology, possibly caused by a virus or virus-triggered immunopathology. The virus might reactivate after years of latency and lyse oligodendrocytes, as in progressive multifocal leukoencephalopathy, or initiate immunopathological demyelination, as in animals infected with Theiler’s murine encephalomyelitis virus or coronaviruses. The argument for a viral cause of MS is supported by epidemiological analyses and studies of MS in identical twins, indicating that disease is acquired. However, the most important evidence is the presence of bands of oligoclonal IgG (OCBs) in MS brain and CSF that persist throughout the lifetime of the patient. OCBs are found almost exclusively in infectious CNS disorders, and antigenic targets of OCBs represent the agent that causes disease. Here, the authors review past attempts to identify an infectious agent in MS brain cells and discuss the promise of using recombinant antibodies generated from clonally expanded plasma cells in brain and CSF to identify disease-relevant antigens. They show how this strategy has been used successfully to analyze antigen specificity in subacute sclerosing panencephalitis, a chronic encephalitis caused by measles virus, and in neuromyelitis optica, a chronic autoimmune demyelinating disease produced by antibodies directed against the aquaporin-4 water channel.

One of the most commonly cited reasons for chronic cannabis use is to cope with stress. Consistent with this, cannabis users have shown reduced emotional arousal and dampened stress reactivity in response to negative imagery. To our knowledge, the present study represents the first to examine the effects of an acute stress manipulation on subjective stress and salivary cortisol in chronic cannabis users compared to non-users. Forty cannabis users and 42 non-users were randomly assigned to complete either the stress or no stress conditions of the Maastricht Acute Stress Test (MAST). The stress condition of the MAST manipulates both physiological (placing hand in ice bath) and psychosocial stress (performing math under conditions of social evaluation). Participants gave baseline subjective stress ratings before, during, and after the stress manipulation. Cortisol was measured from saliva samples obtained before and after the stress manipulation. Further, cannabis cravings and symptoms of withdrawal were measured. Subjective stress ratings and cortisol levels were significantly higher in non-users in the stress condition relative to non-users in the no stress condition. In contrast, cannabis users demonstrated blunted stress reactivity; specifically, they showed no increase in cortisol and a significantly smaller increase in subjective stress ratings. The stress manipulation had no impact on cannabis users' self-reported cravings or withdrawal symptoms. Chronic cannabis use is associated with blunted stress reactivity. Future research is needed to determine whether this helps to confer resiliency or vulnerability to stress-related psychopathology as well as the mechanisms underlying this effect.

Chronic diseases are major causes of disability worldwide with rising prevalence. Most patients suffering from chronic conditions do not always receive optimal care. The Chronic Care Model (CCM) has been developed to help general practitioners making quality improvements. The Patient Assessment of Chronic Illness Care (PACIC) questionnaire was increasingly used in several countries to appraise the implementation of the CCM from the patients' perspective. The objective of this study was to adapt the PACIC questionnaire in the French context and to test the validity of this adaptation in a sample of patients with multiple chronic conditions. The PACIC was translated into French language using a forward/backward procedure. The French version was validated using a sample of 150 patients treated for obstructive sleep apnea syndrome (OSAS) and having multiple chronic co-morbidities. Several forms of validity were analysed: content; face; construct; and internal consistency. The construct validity was investigated with an exploratory factorial analysis. The French-version of the PACIC consisted in 18 items, after merging two pairs of items due to redundancy. The high number of items exhibiting floor/ceiling effects and the non-normality of the ratings suggested that a 5-points rating scale was somewhat inappropriate to assess the patients' experience of care. The construct validity of the French-PACIC was verified and resulted in a bi-dimensional structure. Overall this structure showed a high level of internal consistency. The PACIC score appeared to be significantly related to the age and self-reported health of the patients. A French-version of the PACIC questionnaire is now available to evaluate the patients' experience of care and to monitor the quality improvements realised by the medical structures. This study also pointed out some methodological issues about the PACIC questionnaire, related to the format of the rating scale and to the structure of the questionnaire.

Previous studies have suggested associations of adult exposures to secondhand smoke (SHS) with respiratory symptoms, but no study has focused on blue-collar industrial environments. We assessed the association between SHS and respiratory symptoms in 1,562 non-current smoking U.S. trucking industry workers. Information on SHS exposure and respiratory health was obtained by questionnaire. Multiple logistic regression analyses were used to assess the associations of recent and lifetime exposures to SHS with chronic phlegm, chronic cough, and any wheeze, defined by American Thoracic Society criteria. In analyses adjusted for age, gender, race, childhood SHS exposure, former smoking, pack-years of smoking and years since quitting, body mass index, job title, region of the country, and urban residence, recent exposures to SHS were associated with all three respiratory symptoms (odds ratio (OR) = 1.46; 95% confidence interval (CI) = 1.00-2.13) for chronic cough, 1.55 (95% CI = 1.08-2.21) for chronic phlegm, and 1.76 (95% CI = 1.41-2.21) for any wheeze). Workplace exposure was the most important recent exposure. Childhood exposure to SHS was also associated with all three symptoms, but only statistically significantly for chronic phlegm (OR = 1.84; 95% CI = 1.24-2.75). Additional years of living with a smoker were associated with an increased risk, but there was no evidence of a dose-response, except for chronic phlegm. In this group of trucking industry workers, childhood and recent exposures to SHS were related to respiratory symptoms.

Objective Non-Latino blacks experience a higher proportion of chronic illness and associated disabilities than non-Latino whites. Posttraumatic stress disorder (PTSD) is associated with a greater risk of chronic illness, although few studies have investigated whether the interaction of PTSD with racial disparities may lead to a greater risk of chronic illness among blacks with PTSD than among whites with PTSD. Methods We evaluated data from the population-based National Survey of American Life and the National Comorbidity Survey Replication to investigate the association between race, lifetime PTSD and self-reported chronic illness. Weighted linear and Poisson regression models assessed differences in the magnitude of association between PTSD and chronic illness by race on both the additive and multiplicative scales. Results The magnitude of the association between lifetime PTSD and diabetes was greater among blacks (RD 0.07, 95% CI 0.02, 0.11; RR 1.9, 95% CI 1.4, 2.5) than whites (RD 0.004, 95% CI −0.02, 0.03; RR 1.2, 95% CI 0.7, 1.9) on the additive (p=0.017) scale. The magnitude of the association between lifetime PTSD and heart disease was greater among blacks (RD 0.09, 95% CI 0.05, 0.13) than whites (RD 0.04, 95% CI 0.01, 0.07) on the additive scale at a level approaching significance (p=0.051). Conclusion A lifetime history of PTSD was associated with a significantly greater risk of diabetes among blacks as compared to whites. These findings suggest that continuous exposure to racial inequalities may be associated with a greater risk of PTSD-related health sequela. PMID:27212665

Inflammation is a complex, biologic event that aims to protect and repair tissue. Previous studies suggest that inflammation is critical to induce a healing response following acute injury; however, whether similar inflammatory responses occur as a result of beneficial, non-injurious loading is unknown. The objective of this study was to screen for alterations in a subset of inflammatory and extracellular matrix genes to identify the responses of rat supraspinatus tendon and muscle to a known, non-injurious loading condition. We sought to define how a subset of genes representative of specific inflammation and matrix turnover pathways is altered in supraspinatus tendon and muscle 1) acutely following a single loading bout and 2) chronically following repeated loading bouts. In this study, Sprague-Dawley rats in the acute group ran a single bout of non-injurious exercise on a flat treadmill (10 m/min, 1 hour) and were sacrificed 12 or 24 hours after. Rats in the chronic group ran 5 days/wk for 1 or 8 weeks. A control group maintained normal cage activity. Supraspinatus muscle and tendon were harvested for RNA extractions, and a custom Panomics QuantiGene 2.0 multiplex assay was used to detect 48 target and 3 housekeeping genes. Muscle/tendon and acute/chronic groups had distinct gene expression. Components of the arachidonic acid cascade and matrix metalloproteinases and their inhibitors were altered with acute and chronic exercise. Collagen expression increased. Using a previously validated model of non-injurious exercise, we have shown that supraspinatus tendon and muscle respond to acute and chronic exercise by regulating inflammatory- and matrix turnover-related genes, suggesting that these pathways are involved in the beneficial adaptations to exercise.

To determine injury risk-workload associations in collegiate American Football. Retrospective analysis. Workload and injury data was recorded from 52 players during a full NCAA football season. Acute, chronic, and a range of acute:chronic workload ratios (ACWR: 7:14, 7:21 and 7:28 day) calculated using rolling and exponentially weighted moving averages (EWMA) were plotted against non-contact injuries (regardless of time lost or not) sustained within 3- and 7-days. Injury risks were also determined relative to position and experience. 105 non-contact injuries (18 game- and 87 training-related) were observed with almost 40% sustained during the pre-season. 7-21 day EWMA ACWR's with a 3-day injury lag were most closely associated with injury (R 2 =0.54). Relative injury risks were >3× greater with high compared to moderate and low ratios and magnified when combined with low 21-day chronic workloads (injury probability=92.1%). Injury risks were similar across positions. 'Juniors' presented likely and possibly increased overall injury risk compared to 'Freshman' (RR: 1.94, CI 1.07-3.52) and 'Seniors' (RR: 1.7, CI 0.92-3.14), yet no specific ACWR - experience or - position interactions were identified. High injury rates during college football pre-season training may be associated with high acute loads. In-season injury risks were greatest with high ACWR and evident even when including (more common and less serious) non-time loss injuries. Substantially increased injury risks when low 21-day chronic workloads and concurrently high EWMA ACWR highlights the importance of load management for individuals with chronic game- (non-involved on game day) and or training (following injury) absences.

Cancer survivors may experience long-term and late effects from treatment that adversely affect health and limit functioning. Few studies examine lost productivity and disease burden in cancer survivors compared with individuals who have other chronic conditions or by cancer type. We identified 4960 cancer survivors and 64,431 other individuals from the 2008-2010 Medical Expenditure Panel Survey and compared multiple measures of disease burden, including health status and lost productivity, between conditions and by cancer site for cancer survivors. All analyses controlled for the effects of age, sex, race/ethnicity, and number of comorbid conditions. Overall, in adjusted analyses in multiple models, cancer survivors with another chronic disease (heart disease or diabetes) experienced higher levels of burden compared with individuals with a history of cancer only, chronic disease only, and neither cancer, heart disease, nor diabetes across multiple measures (P < .05). Among cancer survivors, individuals with short survival cancers and multiple cancers consistently had the highest levels of burden across multiple measures (P < .0001). Cancer survivors who have another chronic disease experience more limitations and higher levels of burden across multiple measures. Limitations are particularly severe in cancer survivors with short survival cancer and multiple cancers. © 2013 American Cancer Society.

2017-02-01

Non-communicable diseases (i.e., chronic diseases including cardiovascular disease, cancer, chronic respiratory disease, diabetes and obesity) result in 36 million deaths each year. Individuals' habitual participation in a single health-risk behaviors substantially contribute to morbidity and mortality (e.g., tobacco use, daily fast food intake, etc.); however, more concerning is the impact of typically co-occurring or clustering of multiple health-risk behaviors. This burden can be minimized through successful cessation of health-risk behaviors and adoption of healthy behaviors; namely healthy lifestyle adoption or multiple health behavior change (MHBC). MHBC is a developing field and future research recommendations are provided to advance MHBC research. A valid measure of MHBC (i.e., lifestyle) is warranted to provide the needed basis for MHBC investigations and evaluations. MHBC is thought to occur through shared co-variation of underlying motivating mechanisms, but how these relationships influence behavior remains unclear. A better understanding of the relationship between behaviors and the related motivating mechanisms (and potential cross-relationship of influences) is needed. Future research should also aim to improve lifestyles through understanding how to change multiple health behaviors. Finally, MHBC research should target the development of sustainable interventions which result in lasting effects (e.g., capacity, systems, policy and environmental changes), with dissemination considered during development. Focusing MHBC research in these areas will increase our understanding and maximize the impact on the health of populations.

Neuro-immune interactions at barrier surfaces

Multidirectional interactions between the nervous and immune systems have been documented in homeostasis and pathologies ranging from multiple sclerosis to autism, and from leukemia to acute and chronic inflammation. Recent studies have addressed this crosstalk using cell-specific targeting, novel sequencing, imaging and analytical tools, shedding light on unappreciated mechanisms of neuro-immune regulation. This review focuses on neuro-immune interactions at barrier surfaces, mostly the gut, but also including the skin and the airways, areas densely populated by neurons and immune cells that constantly sense and adapt to tissue-specific environmental challenges.

Uterine and placental pathology can be a major cause of morbidity and mortality in the parturient and infant. When presenting alone, placental abruption, uterine rupture, or placenta accreta can result in significant peripartum hemorrhage, requiring aggressive surgical and anesthetic management; however, the presence of multiple concurrent uterine and placental pathologies can result in significant morbidity and mortality. We present the anesthetic management of a parturient who underwent an urgent cesarean delivery for non-reassuring fetal tracing in the setting of chronic hypertension, preterm premature rupture of membranes, and chorioamnionitis who was subsequently found to have placental abruption, uterine rupture, and placenta accreta.

Heroin addiction is a chronic, relapsing brain disease. Genetic factors are involved in the development of drug addiction. The aim of this study was to determine whether specific variants in genes of the opioid system are associated with non-dependent opioid use and heroin dependence. Genetic information from four subject groups was collected: non-dependent opioid users (NOD) [n=163]; opioid-dependent (OD) patients in methadone maintenance treatment (MMT) [n=143]; opioid-dependent MMT-resistant patients in heroin-assisted treatment (HAT) [n=138]; and healthy controls with no history of opioid use (HC) [n=153]. Eighty-two variants in eight opioid system genes were studied. To establish the role of these genes in (a) non-dependent opioid use, and (b) heroin dependence, the following groups were compared: HC vs. NOD; HC vs. OD (MMT+HAT); and NOD vs. OD (MMT+HAT). Five unique SNPs in four genes showed nominally significant associations with non-dependent opioid use and heroin dependence. The association of the delta opioid receptor (OPRD1) intronic SNP rs2236861 with non-dependent opioid use (HC vs. NOD) remained significant after correction for multiple testing (OR=0.032; p corrected =0.015). This SNP exhibited a significant gene-gene interaction with prepronociceptin (PNOC) SNP rs2722897 (OR=5.24; p corrected =0.041) (HC vs. NOD). This study identifies several new and some previously reported associations of variants with heroin dependence and with non-dependent opioid use, an important and difficult to obtain group not extensively studied previously. Further studies are warranted to confirm and elucidate the potential roles of these variants in the vulnerability to illicit drug use and drug addiction. Copyright © 2016 Elsevier Ireland Ltd.

Chronic pancreatitis with multiple pseudocysts and pancreatic panniculitis: A case report.

PubMed

Gu, Yuqing; Qian, Zhuyin

2018-06-01

Pancreatic pseudocyst can present single or multiple, inside or outside the pancreas. Pancreatic panniculitis is a rare skin lesion in pancreatic disease patients. The purpose of this study is to report a case of chronic pancreatitis coexisting with multiple pseudocysts and pancreatic panniculitis. A 46-year-old man with chronic pancreatitis presented multiple small cystic lesions inside the head of the pancreas and two large cystic lesions adjacent to the tail of the pancreas. The patient also developed subcutaneous nodules involving upper and lower limbs, hands, and lower abdomen bilaterally. The patient was diagnosed with pancreatic pseudocyst and pancreatic panniculitis resulted from chronic pancreatitis. Bile duct stent and pancreatic duct stent placement was performed endoscopicly. Panniculitis faded three weeks later and the pancreatic pseudocysts disappeared six weeks later. Clinicians should be aware of the manifestation of multiple pancreatic pseudocyst and pancreatic panniculitis, and endoscopic transpapillary drainage may be a effective way in this scenario.

Gut-Liver Axis Derangement in Non-Alcoholic Fatty Liver Disease.

Poeta, Marco; Pierri, Luca; Vajro, Pietro

2017-08-02

Non-alcoholic fatty liver disease (NAFLD) is the most frequent type of chronic liver disease in the pediatric age group, paralleling an obesity pandemic. A "multiple-hit" hypothesis has been invoked to explain its pathogenesis. The "first hit" is liver lipid accumulation in obese children with insulin resistance. In the absence of significant lifestyle modifications leading to weight loss and increased physical activity, other factors may act as "second hits" implicated in liver damage progression leading to more severe forms of inflammation and hepatic fibrosis. In this regard, the gut-liver axis (GLA) seems to play a central role. Principal players are the gut microbiota, its bacterial products, and the intestinal barrier. A derangement of GLA (namely, dysbiosis and altered intestinal permeability) may promote bacteria/bacterial product translocation into portal circulation, activation of inflammation via toll-like receptors signaling in hepatocytes, and progression from simple steatosis to non-alcoholic steato-hepatitis (NASH). Among other factors a relevant role has been attributed to the farnesoid X receptor, a nuclear transcriptional factor activated from bile acids chemically modified by gut microbiota (GM) enzymes. The individuation and elucidation of GLA derangement in NAFLD pathomechanisms is of interest at all ages and especially in pediatrics to identify new therapeutic approaches in patients recalcitrant to lifestyle changes. Specific targeting of gut microbiota via pre-/probiotic supplementation, feces transplantation, and farnesoid X receptor modulation appear promising.

Introduction The burden of chronic disease is a global phenomenon, particularly among people aged 65 years and older. More than half of older adults have more than one chronic disease and their care is not optimal. Chronic disease management (CDM) tools have the potential to meet this challenge but they are primarily focused on a single disease, which fails to address the growing number of seniors with multiple chronic conditions. Methods and analysis We will conduct a systematic review alongside a realist review to identify effective CDM tools that integrate one or more high-burden chronic diseases affecting older adults and to better understand for whom, under what circumstances, how and why they produce their outcomes. We will search MEDLINE, EMBASE, CINAHL, AgeLine and the Cochrane Library for experimental, quasi-experimental, observational and qualitative studies in any language investigating CDM tools that facilitate optimal disease management in one or more high-burden chronic diseases affecting adults aged ≥65 years. Study selection will involve calibration of reviewers to ensure reliability of screening and duplicate assessment of articles. Data abstraction and risk of bias assessment will also be performed independently. Analysis will include descriptive summaries of study and appraisal characteristics, effectiveness of each CDM tool (meta-analysis if appropriate); and a realist programme theory will be developed and refined to explain the outcome patterns within the included studies. Ethics and dissemination Ethics approval is not required for this study. We anticipate that our findings, pertaining to gaps in care across high-burden chronic diseases affecting seniors and highlighting specific areas that may require more research, will be of interest to a wide range of knowledge users and stakeholders. We will publish and present our findings widely, and also plan more active dissemination strategies such as workshops with our key stakeholders.

AIM To evaluate the efficacy of peripheral blood concentrations of angiopoietins (Ang) as cirrhosis biomarkers of chronic hepatitis C (CHC). METHODS Ang1 and Ang2 serum levels were measured by enzyme-linked immunosorbent assays (ELISA) in samples from 179 cirrhotic and non-cirrhotic CHC patients, classified according to the METAVIR system. Groups were compared by non-parametric Mann-Whitney U test. Subsequently, the association of peripheral concentrations of angiopoietins with the stage of fibrosis was analyzed using Spearman correlation test. Finally, the accuracy, sensitivity and specificity of circulating angiopoietins for cirrhosis diagnosis were determined by the study of the respective area under the curve of receiver operator characteristics (AUC-ROC). RESULTS Peripheral blood concentrations of Ang1 and Ang2 in CHC patients were significantly related to fibrosis. While Ang1 was decreased in cirrhotic subjects compared to non-cirrhotic (P < 0.0001), Ang2 was significantly increased as CHC progressed to the end stage of liver disease (P < 0.0001). Consequently, Ang2/Ang1 ratio was notably amplified and significantly correlated with fibrosis (P < 0.0001). Interestingly, the individual performance of each angiopoietin for the diagnosis of cirrhosis reached notable AUC-ROC values (above 0.7, both), but the Ang2/Ang1 ratio was much better (AUC-ROC = 0.810) and displayed outstanding values of sensitivity (71%), specificity (84%) and accuracy (82.1%) at the optimal cut-off (10.33). Furthermore, Ang2/Ang1 ratio improved the performance of many other previously described biomarkers or scores of liver cirrhosis in CHC. CONCLUSION Ang2/Ang1 ratio might constitute a useful tool for monitoring the progression of chronic liver disease towards cirrhosis and play an important role as therapeutic target. PMID:27956798

Opioid abuse has continued to increase at an alarming rate since the 1990 s. As documented by different medical specialties, medical boards, advocacy groups, and the Drug Enforcement Administration, available evidence suggests a wide variance in chronic opioid therapy of 90 days or longer in chronic non-cancer pain. Part 1 describes evidence assessment. The objectives of opioid guidelines as issued by the American Society of Interventional Pain Physicians (ASIPP) are to provide guidance for the use of opioids for the treatment of chronic non-cancer pain, to produce consistency in the application of an opioid philosophy among the many diverse groups involved, to improve the treatment of chronic non-cancer pain, and to reduce the incidence of abuse and drug diversion. The focus of these guidelines is to curtail the abuse of opioids without jeopardizing non-cancer pain management with opioids. 1) There is good evidence that non-medical use of opioids is extensive; one-third of chronic pain patients may not use prescribed opioids as prescribed or may abuse them, and illicit drug use is significantly higher in these patients. 2) There is good evidence that opioid prescriptions are increasing rapidly, as the majority of prescriptions are from non-pain physicians, many patients are on long-acting opioids, and many patients are provided with combinations of long-acting and short-acting opioids. 3) There is good evidence that the increased supply of opioids, use of high dose opioids, doctor shoppers, and patients with multiple comorbid factors contribute to the majority of the fatalities. 4) There is fair evidence that long-acting opioids and a combination of long-acting and short-acting opioids contribute to increasing fatalities and that even low-doses of 40 mg or 50 mg of daily morphine equivalent doses may be responsible for emergency room admissions with overdoses and deaths. 5) There is good evidence that approximately 60% of fatalities originate from opioids prescribed within the guidelines, with approximately 40% of fatalities occurring in 10% of drug abusers. 6) The short-term effectiveness of opioids is fair, whereas the long-term effectiveness of opioids is limited due to a lack of long-term (> 3 months) high quality studies, with fair evidence with no significant difference between long-acting and short-acting opioids. 7) Among the individual drugs, most opioids have fair evidence for short-term and limited evidence for long-term due to a lack of quality studies. 8) The evidence for the effectiveness and safety of chronic opioid therapy in the elderly for chronic non-cancer pain is fair for short-term and limited for long-term due to lack of high quality studies; limited in children and adolescents and patients with comorbid psychological disorders due to lack of quality studies; and the evidence is poor in pregnant women. 9) There is limited evidence for reliability and accuracy of screening tests for opioid abuse due to lack of high quality studies. 10) There is fair evidence to support the identification of patients who are non-compliant or abusing prescription drugs or illicit drugs through urine drug testing and prescription drug monitoring programs, both of which can reduce prescription drug abuse or doctor shopping. The guidelines are based on the best available evidence and do not constitute inflexible treatment recommendations. Due to the changing body of evidence, this document is not intended to be a "standard of care."

The purpose of the study is to evaluate the feasibility of a newly developed parent program for parents of children with non-specific chronic musculoskeletal pain. This program is part of the child's interdisciplinary outpatient pain rehabilitation treatment. The goal of the parent program is to change parent's thoughts/behaviour regarding pain with the ultimate intention to further improve their child's functioning. There were two main objectives in the study: First, to evaluate the feasibility of the parent program. Second, to evaluate changing in parental behavioral factors pre- and posttreatment. Participants were parents of adolescents, who underwent a interdisciplinary outpatient pain program for non-specific chronic musculoskeletal pain. Parents participated in a parent program as part of their child's treatment. Adolescents reported their level of disability, pain intensity, fear of pain and pain catastrophizing by filling out questionnaires. Parents reported catastrophic thinking about their child's pain, fear of pain and disabilities of their child. In addition, they evaluated the parent program. Sixty five parents (36 mothers and 29 fathers) of 44 adolescents filled in the baseline questionnaires. Result showed significant and clinically relevant improvements for both parents as well for adolescents. Parents were positive about the content of the parent program, they evaluated the program as supportive and informative. Adding a parent program to a interdisciplinary outpatient pain program for adolescent with chronic musculoskeletal pain, seems to be feasible in daily life of the parents and results in positive behavioural changes for both parents and adolescents. A parent program, designed to change cognition and behaviour of parents of children with chronic musculoskeletal pain is feasible. © 2017 European Pain Federation - EFIC®.

Insulin resistance and oxidative stress interdependency in non-alcoholic fatty liver disease.

PubMed

Videla, Luis A; Rodrigo, Ramón; Araya, Julia; Poniachik, Jaime

2006-12-01

Non-alcoholic fatty liver disease (NAFLD) is emerging as a major cause of chronic liver disease in association with the rising prevalence of obesity and type 2 diabetes in the population. Oxidative stress and insulin resistance (IR) are major contributors in the pathogenesis of NAFLD and in the progression from steatosis to steatohepatitis. Recently, Houstis and colleagues reported that reactive oxygen species have a causal role in multiple forms of IR, a phenomenon that can further promote exacerbation of oxidative stress. The improvement of the knowledge of these interrelationships should contribute to elucidate pathogenic pathways and design effective treatments for NAFLD.

Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (i.e., chronic post-surgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (i.e., surgery, viral infection, injury, and toxic/noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

Chronic pancreatitis is an inflammatory disease of the pancreas characterized by progressive tissue destruction and fibrogenesis. The development of chronic pancreatitis is associated with immune cell dysregulation. Currently, the specific and effective treatment of chronic pancreatitis remains absent. By using an L-arginine induced chronic pancreatitis mouse model, we tested the therapeutic potential of hydrogen, a strong hydroxyl radicals scavenger, in the chronic pancreatitis model. Tissue inflammation, damage and fibrosis were analyzed on HE, TUNEL, MPO, and sirius staining. Pancreas levels of MDA content, SOD activity, TNF-α , IL-10 cytokine expression and serum amylase and lipase activity were determined by ELISA and absorbance assay. Apoptosis, T cells subtype proportion and intracellular level of reactive oxygen species (ROS) were analyzed by flow cytometry. Tregs adoptive transfer and CD25 neutralization were used to validate the role of Tregs in chronic pancreatitis. We found that hydrogen treatment significantly improved multiple symptoms of chronic pancreatitis. The number of Tregs was reduced in chronic pancreatitis mice, while hydrogen treatment restored the Treg loss by L-arginine administrations. Depletion of Tregs abolished the protective effect of hydrogen treatment in chronic pancreatitis. In vitro study showed that hydrogen blocked ROS generation in Tregs and promoted Tregs survival. Hydrogen treatment showed reliable benefits in controlling the severity of chronic pancreatitis. Our study supported that hydrogen could be used as a novel treatment in chronic pancreatitis patient in the future. © 2017 The Author(s). Published by S. Karger AG, Basel.

Managing multiple chronic health conditions is a significant challenge. The purpose of this study was to examine the experience and management of chronic pain among adult patients with other complex chronic conditions, specifically diabetes and heart failure (HF). We surveyed 624 US Department of Veterans Affairs primary care patients in 3 study groups: 184 with HF, 221 with diabetes, and 219 general primary care users. We compared health status and function between those with and without chronic pain within the 3 study groups. Among those with chronic pain, we compared pain location, severity, and treatment across groups. More than 60% in each group reported chronic pain, with the majority reporting pain in the back, hip, or knee. In all groups, patients with chronic pain were more likely to report fair or poor health than those without pain (P<0.05). In the HF and diabetes groups, a higher percentage of patients with pain were not working because of health reasons. Of those with pain, more than 70% in each group took medications for pain; more than one-half managed pain with rest or sedentary activities; and less than 50% used exercise for managing their pain. Chronic pain is a prevalent problem that is associated with poor functioning among multimorbid patients. Better management of chronic pain among complex patients could lead to significant improvements in health status, functioning, and quality of life and possibly also improve the management of their other major chronic health conditions.

Chronic wounds, including diabetic foot ulcers (DFU), pressure ulcers (PU), and venous ulcers (VU) result from multiple physiologic impairments. Operative debridement is a mainstay of treatment to remove nonviable tissue and to stimulate wound healing. Unlike tumor resection, however, operative wound specimens are not routinely sent for pathology. The objective of this study was to describe the pathology present in chronic wounds. Pathology reports of the skin edge and wound base from 397 initial debridements in 336 consecutive patients with chronic wounds were retrospectively reviewed. All data were entered and stored in a Wound Electronic Medical Record. Pathology data were extracted from the Wound Electronic Medical Record, coded, and quantified. Up to 15 distinct histopathologic findings across 7 tissue types were observed after review of pathology reports from chronic wounds. Specifically, the pathology of epidermis revealed hyperkeratosis: 66% in DFUs, 31% in PUs, and 29% in VUs. Dermal pathology revealed fibrosis in 49% of DFUs, 30% of PUs, and 15% of VUs. Wound bed pathology revealed necrosis in the subcutaneous tissue in 67% of DFUs, 55% of PUs, and 19% of VUs. Fibrosis was reported in between 19% and 52% of all wound types. Acute osteomyelitis was present in 39% of DFUs, 33% of PUs, and 29% of VUs. This observational study of the histopathology of initial surgical debridement of chronic wounds revealed a wide range of findings across multiple tissue levels. Although certain findings such as osteomyelitis and gangrene have been shown to directly relate to impaired wound healing and amputation, other findings require additional investigation. To rigorously define a margin of debridement, a prospective study relating histopathology and clinical outcomes such as healing rates and amputation is needed.

Prior to the introduction of Haemophilus influenzae type b (Hib) conjugate vaccines, invasive Hib disease affected almost exclusively children. According to some recent studies, in the postvaccine era, adults, the elderly, and immunocompromised persons can be affected more often than children. As the production of type-specific anti-capsular polysaccharide antibodies is the major defense mechanism against Hib, individuals with defects in humoral immune responses have high susceptibility to infections caused by Hib. We hypothesized that nonvaccinated adults with chronic conditions causing immunosuppression may lack protective antibody to Hib. We assessed serum anti-Hib IgG levels and bactericidal activity in 59 patients with chronic renal failure, 30 patients with type 2 diabetes mellitus, 28 patients with chronic obstructive pulmonary disease (COPD), and 20 patients with multiple myeloma compared to 32 healthy controls of similar age. Considering antibody at >0.15 μg/ml as the protective correlate in unvaccinated individuals, we detected subprotective Hib antibody levels in 29% of chronic renal failure, 20% of diabetes, 14% of COPD, and 55% of myeloma patients compared to 3% of healthy controls. Additionally, 70% of myeloma and 58% of chronic renal failure patients did not have detectable serum bactericidal activity against Hib. Among individuals with severe diseases causing secondary immunodeficiency, patients with multiple myeloma and chronic renal failure are at an increased risk of invasive Hib disease. Considering that Hib continues to circulate in the population, this study provides a rationale for the immunization of some adult patients with secondary immunodeficiency with the pediatric Hib vaccine to achieve protective immunity.

The effectiveness and cost-evaluation of manual therapy and physical therapy in patients with sub-acute and chronic non specific neck pain. Rationale and design of a Randomized Controlled Trial (RCT)

PubMed Central

2010-01-01

Background Manual Therapy applied to patients with non specific neck pain has been investigated several times. In the Netherlands, manual therapy as applied according to the Utrecht School of Manual Therapy (MTU) has not been the subject of a randomized controlled trial. MTU differs in diagnoses and treatment from other forms of manual therapy. Methods/Design This is a single blind randomized controlled trial in patients with sub-acute and chronic non specific neck pain. Patients with neck complaints existing for two weeks (minimum) till one year (maximum) will participate in the trial. 180 participants will be recruited in thirteen primary health care centres in the Netherlands. The experimental group will be treated with MTU during a six week period. The control group will be treated with physical therapy (standard care, mainly active exercise therapy), also for a period of six weeks. Primary outcomes are Global Perceived Effect (GPE) and functional status (Neck Disability Index (NDI-DV)). Secondary outcomes are neck pain (Numeric Rating Scale (NRS)), Eurocol, costs and quality of life (SF36). Discussion This paper presents details on the rationale of MTU, design, methods and operational aspects of the trial. Trial registration ClinicalTrials.gov Identifier: NCT00713843 PMID:20096136

Because of the limitations of liver biopsy, reliable non-invasive serum biomarkers of liver fibrosis are needed. The aim of this study was to identify such markers by the use of serum proteomics in chronic hepatitis B (CHB). Two-dimensional gel electrophoresis (2-DE) was used to identify differentially expressed protein spots in sera from 40 CHB patients [20 with mild fibrosis (S0-S1) and 20 with severe fibrosis (S3-S4)]. Mass spectrometry (MS) based multiple reaction monitoring (MRM) was used to quantify peptide ions of differential protein spots in another set of sera from 86 CHB patients with different liver fibrosis (S0-S4). Seven differentially expressed protein spots were found by 2-DE. Fourteen peptide ions of seven target protein spots were quantified by MS-based MRM. Summed peak areas ratio (SPAR) values of peptide ions from protein spot 1, 4 and 8, identified as apo serum transferrin, complement component C3c and transferrin, were significantly different from non-fibrosis (S0) to fibrosis stage 4. AUROCs of models established by peptide ions (protein spot 1, 4, 8) and model consisting of a combination of all ions were 0.848∼0.966 (S2-S4 versus S0-S1) and 0.785∼0.875 (S3-S4 versus S0-S2). Only the peptide ions model of transferrin had better sensitivity and specificity for predicting fibrosis stages than did aspartate aminotransferase-to-platelet ratio index (APRI), FIB-4 and Forn's index. Serum peptide ions of transferrin, detected by proteomic MRM, are new and promising biomarkers for staging liver fibrosis in CHB patients. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Although spousal support has been linked to positive outcomes in various health-related contexts, some research has found that the amount of social support provided to those who are chronically ill deteriorates over time. The current study refines the literature by considering multiple factors associated with spouses' provision of emotional support to partners with Type 2 diabetes. This diary study (N = 126 couples) examined the roles that stressor (disease severity and diabetes-specific anxiety), recipient (negative and positive affect), provider (negative and positive affect), and relationship (tension and enjoyment) factors play in spouses' provision of emotional support. Daily disease severity, patients' and spouses' daily negative affect, and spouses' daily relationship enjoyment were predictors of support provision. Wives, but not husbands, provided more support on days when patients experienced diabetes-specific anxiety. Results advance understanding of support provision in the context of a chronic stressor.

Estrogen anti-inflammatory activity in brain: a therapeutic opportunity for menopause and neurodegenerative diseases

PubMed Central

Vegeto, Elisabetta; Benedusi, Valeria; Maggi, Adriana

2008-01-01

Recent studies highlight the prominent role played by estrogens in protecting the central nervous system (CNS) against the noxious consequences of a chronic inflammatory reaction. The neurodegenerative process of several CNS diseases, including Multiple Sclerosis, Alzheimer’s and Parkinson’s Diseases, is associated with the activation of microglia cells, which drive the resident inflammatory response. Chronically stimulated during neurodegeneration, microglia cells are thought to provide detrimental effects on surrounding neurons. The inhibitory activity of estrogens on neuroinflammation and specifically on microglia might thus be considered as a beneficial therapeutic opportunity for delaying the onset or progression of neurodegenerative diseases; in addition, understanding the peculiar activity of this female hormone on inflammatory signalling pathways will possibly lead to the development of selected anti-inflammatory molecules. This review summarises the evidence for the involvement of microglia in neuroinflammation and the anti-inflammatory activity played by estrogens specifically in microglia. PMID:18522863

Brain-derived neurotrophic factor levels under chronic natalizumab treatment in multiple sclerosis. A preliminary report.

Văcăraş, Vitalie; Major, Zoltán Zsigmond; Buzoianu, Anca Dana

Our main purpose was to investigate if the chronic treatment with the disease-modifying drug natalizumab shows quantifiable effect on BDNF levels in multiple sclerosis patients. BDNF plasma concentration was evaluated using enzyme-linked immunosorbent assay in healthy individuals, not treated multiple sclerosis patients and patients treated with natalizumab. Multiple sclerosis patients have a significantly lower amount of peripheral BDNF than healthy individuals. Patients treated with natalizumab have significantly higher BDNF levels than not treated patients.

The proportion of people in the United States with multiple chronic medical conditions (MCMC) is increasing. Yet, little is known about the relationship that race, ethnicity, and psychiatric disorders have on the prevalence of MCMCs in the general population. This study used data from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N=33,107). Multinomial logistic regression models adjusting for sociodemographic variables, body mass index, and quality of life were used to examine differences in the 12-month prevalence of MCMC by race/ethnicity, psychiatric diagnosis, and the interactions between race/ethnicity and psychiatric diagnosis. Compared to non-Hispanic Whites, Hispanics reported lower odds of MCMC and African Americans reported higher odds of MCMC after adjusting for covariates. People with psychiatric disorders reported higher odds of MCMC compared with people without psychiatric disorders. There were significant interactions between race and psychiatric diagnosis associated with rates of MCMC. In the presence of certain psychiatric disorders, the odds of MCMC were higher among African Americans with psychiatric disorders compared to non-Hispanic Whites with similar psychiatric disorders. Our study results indicate that race, ethnicity, and psychiatric disorders are associated with the prevalence of MCMC. As the rates of MCMC rise, it is critical to identify which populations are at increased risk and how to best direct services to address their health care needs.

HFE gene in primary and secondary hepatic iron overload

Sebastiani, Giada; Walker, Ann P

2007-01-01

Distinct from hereditary haemochromatosis, hepatic iron overload is a common finding in several chronic liver diseases. Many studies have investigated the prevalence, distribution and possible contributory role of excess hepatic iron in non-haemochromatotic chronic liver diseases. Indeed, some authors have proposed iron removal in liver diseases other than hereditary haemochromatosis. However, the pathogenesis of secondary iron overload remains unclear. The High Fe (HFE) gene has been implicated, but the reported data are controversial. In this article, we summarise current concepts regarding the cellular role of the HFE protein in iron homeostasis. We review the current status of the literature regarding the prevalence, hepatic distribution and possible therapeutic implications of iron overload in chronic hepatitis C, hepatitis B, alcoholic and non-alcoholic fatty liver diseases and porphyria cutanea tarda. We discuss the evidence regarding the role of HFE gene mutations in these liver diseases. Finally, we summarize the common and specific features of iron overload in liver diseases other than haemochromatosis. PMID:17729389

The causes of the large and persistent Black-White disparity in preterm birth (PTB) are unknown. It is biologically plausible that chronic stress across a woman's life course could be a contributor. Prior research suggests that chronic worry about experiencing racial discrimination could affect PTB through neuroendocrine, vascular, or immune mechanisms involved in both responses to stress and the initiation of labor. This study aimed to examine the role of chronic worry about racial discrimination in Black-White disparities in PTB. The data source was cross-sectional California statewide-representative surveys of 2,201 Black and 8,122 White, non-Latino, U.S.-born postpartum women with singleton live births during 2011-2014. Chronic worry about racial discrimination (chronic worry) was defined as responses of "very often" or "somewhat often" (vs. "not very often" or "never") to the question: "Overall during your life until now, how often have you worried that you might be treated or viewed unfairly because of your race or ethnic group?" Prevalence ratios (PRs) with 95% Confidence Intervals (CI) were calculated from sequential logistic regression models, before and after adjustment for multiple social/demographic, behavioral, and medical factors, to estimate the magnitude of: (a) PTB risks associated with chronic worry among Black women and among White women; and (b) Black-White disparities in PTB, before and after adjustment for chronic worry. Among Black and White women respectively, 36.9 (95% CI 32.9-40.9) % and 5.5 (95% CI 4.5-6.5) % reported chronic worry about racial discrimination; rates were highest among Black women of higher income and education levels. Chronic worry was significantly associated with PTB among Black women before (PR 1.73, 95% CI 1.12-2.67) and after (PR 2.00, 95% CI 1.33-3.01) adjustment for covariates. The unadjusted Black-White disparity in PTB (PR 1.59, 95%CI 1.21-2.09) appeared attenuated and became non-significant after adjustment for chronic worry (PR 1.30, 95% CI 0.93-1.81); it appeared further attenuated after adding the covariates (PR 1.17, 95% CI 0.85-1.63). Chronic worry about racial discrimination may play an important role in Black-White disparities in PTB and may help explain the puzzling and repeatedly observed greater PTB disparities among more socioeconomically-advantaged women. Although the single measure of experiences of racial discrimination used in this study precluded examination of the role of other experiences of racial discrimination, such as overt incidents, it is likely that our findings reflect an association between one or more experiences of racial discrimination and PTB. Further research should examine a range of experiences of racial discrimination, including not only chronic worry but other psychological and emotional states and both subtle and overt incidents as well. These dramatic results from a large statewide-representative study add to a growing-but not widely known-literature linking racism-related stress with physical health in general, and shed light on the links between racism-related stress and PTB specifically. Without being causally definitive, this study's findings should stimulate further research and heighten awareness of the potential role of unmeasured social variables, such as diverse experiences of racial discrimination, in racial disparities in health.

Non-tuberculous mycobacterial (NTM) infection of the musculoskeletal tissue is a rare disease. An early and accurate diagnosis is often difficult because of the indolent clinical course and difficulty of isolating pathogens. Our goal was to determine the clinical features of musculoskeletal NTM infection and to present the treatment outcomes. A total of 29 patients (nine females, 20 males between 34 and 85 years old, mean age 61.7 years; 34 to 85) with NTM infection of the musculoskeletal system between 1998 to 2011 were identified and their treatment retrospectively analysed. Microbiological studies demonstrated NTM in 29 patients: the isolates were Mycobacterium intracellulare in six patients, M. fortuitum in three, M. abscessus in two and M. marinum in one. In the remaining patients we failed to identify the species. The involved sites were the hand/wrist in nine patients the knee in five patients, spine in four patients, foot in two patients, elbow in two patients, shoulder in one, ankle in two patients, leg in three patients and multiple in one patient. The mean interval between the appearance of symptoms and diagnosis was 20.8 months (1.5 to 180). All patients underwent surgical treatment and antimicrobial medication according to our protocol for chronic musculoskeletal infection: 20 patients had NTM-specific medication and nine had conventional antimicrobial therapy. At the final follow-up 22 patients were cured, three failed to respond to treatment and four were lost to follow-up. Identifying these diseases due the initial non-specific presentation can be difficult. Treatment consists of surgical intervention and adequate antimicrobial therapy, which can result in satisfactory outcomes. ©2014 The British Editorial Society of Bone & Joint Surgery.

Non-communicable diseases (NCDs) are a large and rapidly-growing problem in China and other middle-income countries. Clinical treatment of NCDs is long-term and expensive, so it may present particular problems for equality and horizontal equity (equal treatment for equal need) in access to health care, although little is known about this at present in low- and middle-income countries. To address this gap, and inform policy for a substantial proportion of the global population, we examined inequality and inequity in general health care utilization (doctor consultations and hospital admissions) and in treatment of chronic conditions (hypertension, hyperglycaemia and dyslipidaemia), in 30 499 Chinese adults aged ≥50 years from one of China's richest provinces, using the Guangzhou Biobank Cohort Study (2003-2008). We used concentration indices to test for inequality and inequity in utilization by household income per head. Inequality was decomposed to show the contributions of income, indicators of 'need for health care' (age, sex, self-rated health, coronary heart disease risk and chronic obstructive pulmonary disease) and non-need factors (education, occupation, out-of-pocket health care payments and health insurance). We found inequality and inequity in treatment of chronic conditions but not in general health care utilization. Using more objective and specific measures of 'need for health care' increased estimates of inequity for treatment of chronic conditions. Income and non-need factors (especially health insurance, education and occupation) made the largest contributions to inequality. Further work is needed on why access to treatment for chronic conditions in China is restricted for those on low incomes and how these inequities can be mitigated.

The purpose of the study was to develop a situation-specific theory for explaining health-related quality of life (QOL) among older South Korean adults with type 2 diabetes. To develop a situation-specific theory, three sources were considered: (a) the conceptual model of health promotion and QOL for people with chronic and disabling conditions (an existing theory related to the QOL in patients with chronic diseases); (b) a literature review using multiple databases including Cumulative Index for Nursing and Allied Health Literature (CINAHL), PubMed, PsycINFO, and two Korean databases; and (c) findings from our structural equation modeling study on health-related QOL in older South Korean adults with type 2 diabetes. The proposed situation-specific theory is constructed with six major concepts including barriers, resources, perceptual factors, psychosocial factors, health-promoting behaviors, and health-related QOL. The theory also provides the interrelationships among concepts. Health care providers and nurses could incorporate the proposed situation-specific theory into development of diabetes education programs for improving health-related QOL in older South Korean adults with type 2 diabetes.

We compared the odds of vitamin D deficiency in three chronic diseases: systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and type 2 diabetes (T2DM), adjusting for medications, demographics, and laboratory parameters, common to all three diseases. We also designed multivariate models to determine whether different factors are associated with vitamin D deficiency in different racial/ethnic groups. We identified all patients with non-overlapping diagnoses of SLE, RA, and T2DM, with 25-hydroxyvitamin D (25OHD) levels measured between 2000 and 2009. Vitamin D deficiency was defined as 25OHD levels <20 ng/ml, based on previously established definitions. Race/ethnicity was analyzed as African-American non-Hispanic (African-American), Hispanic non-African-American (Hispanic), and Other based on self report. We included 3,914 patients in the final analysis: 123 SLE, 100 RA, and 3,691 T2DM. Among African-Americans the frequency of vitamin D deficiency was 59% in SLE, 47% in RA, and 67% in T2DM. Among Hispanics the frequency of vitamin D deficiency was 67% in SLE, 50% in RA, and 59% in T2DM. Compared with the SLE group, the adjusted odds ratio of vitamin D deficiency was 1.1, 95% CI (0.62, 2.1) in the RA group, and 2.0, 95% CI (1.3, 3.1) in the T2DM group. In the multivariate analysis, older age, higher serum calcium and bisphosphonate therapy were associated with a lower odds of vitamin D deficiency in all three racial/ethnic groups: 1,330 African-American, 1,257 Hispanic, and 1,100 Other. T2DM, serum creatinine, and vitamin D supplementation were associated with vitamin D deficiency in some, but not all, racial/ethnic groups. Vitamin D deficiency is highly prevalent in our patients with SLE, RA, and T2DM. While the odds of vitamin D deficiency are similar in RA and SLE patients in a multivariate analysis, T2DM patients have much higher odds of being vitamin D deficient. Different demographic and laboratory factors may be associated with vitamin D deficiency within different racial/ethnic groups. Therefore, disease-specific and race/ethnicity-specific definitions of vitamin D deficiency need to be established in future studies in order to define goals of vitamin D replacement in patients with autoimmune and non-autoimmune chronic diseases.

Non-invasive electrotherapy is commonly used for treatment of chronic low back pain. Evidence for efficacy of most electrotherapy modalities is weak or lacking. This study aims to execute a high-quality, double-blinded randomized controlled clinical trial comparing 1) H-Wave(®) Device stimulation plus usual care with 2) transcutaneous electrical nerve stimulation (TENS) plus usual care, and 3) Sham electrotherapy plus usual care to determine comparative efficacy for treatment of chronic non-specific low back pain patients. Chronic non-specific low back pain patients between ages of 18-65 years, with pain of at least 3 months duration and minimal current 5/10 VAS pain. Patients will have no significant signs or symptoms of lumbosacral nerve impingement, malignancy, spinal stenosis, or mood disorders. Double blind RCT with 3 arms and 38 subjects per arm. Randomization by permuted blocks of random length, stratified by Workers Compensation claim (yes vs. no), and use of opioids. The null hypothesis of this study is that there are no statistically significant differences in functional improvement between treatment types during and at the end of a 12-week week treatment period. Subjective data will be collected using Filemaker Pro™ database management collection tools. Objective data will be obtained through functional assessments. Data will be collected at enrollment and at 1, 4, 8, and 12 weeks for each participant by a blinded assessor. H-Wave(®) device stimulation (Intervention A) plus usual care, transcutaneous electrical nerve stimulation (TENS) (Intervention B) plus usual care, and sham electrotherapy plus usual care (control). Each treatment arm will have identical numbers of visits (4) and researcher contact time (approximately 15 hours). Oswestry Disability Index. Secondary measures include: Rowland Morris Instrument, VAS pain score, functional evaluation including strength when pushing and pulling, pain free range of motion in flexion and extension. Outcome measures assessed at baseline, 1, 4, 8, and 12 weeks. Treatment failure will be defined if patient terminates assigned treatment arm for non-efficacy or undergoes invasive procedure or other excluded cointerventions. Data will be analyzed using intention-to-treat analysis and adjusted for covariates related to LBP (e.g. age) as needed. Study strengths include complex randomization, treatment group allocation concealment, double blinding, controlling for co-interventions, rigorous inclusion criteria, assessment of compliance, plans for limiting dropout, identical assessment methods and timing for each treatment arm, and planned intention-to-treat analyses.

The neural androgen receptor: a therapeutic target for myelin repair in chronic demyelination

Myelin regeneration is a major therapeutic goal in demyelinating diseases, and the failure to remyelinate rapidly has profound consequences for the health of axons and for brain function. However, there is no efficient treatment for stimulating myelin repair, and current therapies are limited to anti-inflammatory agents. Males are less likely to develop multiple sclerosis than females, but often have a more severe disease course and reach disability milestones at an earlier age than females, and these observations have spurred interest in the potential protective effects of androgens. Here, we demonstrate that testosterone treatment efficiently stimulates the formation of new myelin and reverses myelin damage in chronic demyelinated brain lesions, resulting from the long-term administration of cuprizone, which is toxic for oligodendrocytes. In addition to the strong effect of testosterone on myelin repair, the number of activated astrocytes and microglial cells returned to low control levels, indicating a reduction of neuroinflammatory responses. We also identify the neural androgen receptor as a novel therapeutic target for myelin recovery. After the acute demyelination of cerebellar slices in organotypic culture, the remyelinating actions of testosterone could be mimicked by 5α-dihydrotestosterone, a metabolite that is not converted to oestrogens, and blocked by the androgen receptor antagonist flutamide. Testosterone treatment also failed to promote remyelination after chronic cuprizone-induced demyelination in mice with a non-functional androgen receptor. Importantly, testosterone did not stimulate the formation of new myelin sheaths after specific knockout of the androgen receptor in neurons and macroglial cells. Thus, the neural brain androgen receptor is required for the remyelination effect of testosterone, whereas the presence of the receptor in microglia and in peripheral tissues is not sufficient to enhance remyelination. The potent synthetic testosterone analogue 7α-methyl-19-nortestosterone, which has been developed for long-term male contraception and androgen replacement therapy in hypogonadal males and does not stimulate prostate growth, also efficiently promoted myelin repair. These data establish the efficacy of androgens as remyelinating agents and qualify the brain androgen receptor as a promising drug target for remyelination therapy, thus providing the preclinical rationale for a novel therapeutic use of androgens in males with multiple sclerosis.

Non-invasive Markers of Liver Fibrosis: Adjuncts or Alternatives to Liver Biopsy?

Chin, Jun L.; Pavlides, Michael; Moolla, Ahmad; Ryan, John D.

2016-01-01

Liver fibrosis reflects sustained liver injury often from multiple, simultaneous factors. Whilst the presence of mild fibrosis on biopsy can be a reassuring finding, the identification of advanced fibrosis is critical to the management of patients with chronic liver disease. This necessity has lead to a reliance on liver biopsy which itself is an imperfect test and poorly accepted by patients. The development of robust tools to non-invasively assess liver fibrosis has dramatically enhanced clinical decision making in patients with chronic liver disease, allowing a rapid and informed judgment of disease stage and prognosis. Should a liver biopsy be required, the appropriateness is clearer and the diagnostic yield is greater with the use of these adjuncts. While a number of non-invasive liver fibrosis markers are now used in routine practice, a steady stream of innovative approaches exists. With improvement in the reliability, reproducibility and feasibility of these markers, their potential role in disease management is increasing. Moreover, their adoption into clinical trials as outcome measures reflects their validity and dynamic nature. This review will summarize and appraise the current and novel non-invasive markers of liver fibrosis, both blood and imaging based, and look at their prospective application in everyday clinical care.

[Magnetic Resonance Imaging Conversion Predictors of Clinically Isolated Syndrome to Multiple Sclerosis].

PubMed

Peixoto, Sara; Abreu, Pedro

2016-11-01

Clinically isolated syndrome may be the first manifestation of multiple sclerosis, a chronic demyelinating disease of the central nervous system, and it is defined by a single clinical episode suggestive of demyelination. However, patients with this syndrome, even with long term follow up, may not develop new symptoms or demyelinating lesions that fulfils multiple sclerosis diagnostic criteria. We reviewed, in clinically isolated syndrome, what are the best magnetic resonance imaging findings that may predict its conversion to multiple sclerosis. A search was made in the PubMed database for papers published between January 2010 and June 2015 using the following terms: 'clinically isolated syndrome', 'cis', 'multiple sclerosis', 'magnetic resonance imaging', 'magnetic resonance' and 'mri'. In this review, the following conventional magnetic resonance imaging abnormalities found in literature were included: lesion load, lesion location, Barkhof's criteria and brain atrophy related features. The non conventional magnetic resonance imaging techniques studied were double inversion recovery, magnetization transfer imaging, spectroscopy and diffusion tensor imaging. The number and location of demyelinating lesions have a clear role in predicting clinically isolated syndrome conversion to multiple sclerosis. On the other hand, more data are needed to confirm the ability to predict this disease development of non conventional techniques and remaining neuroimaging abnormalities. In forthcoming years, in addition to the established predictive value of the above mentioned neuroimaging abnormalities, different clinically isolated syndrome neuroradiological findings may be considered in multiple sclerosis diagnostic criteria and/or change its treatment recommendations.

In multiple sclerosis (MS), activated microglia and infiltrating macrophages phagocytose myelin focally in (chronic) active lesions. These demyelinating sites expand in time, but at some point turn inactive into a sclerotic scar. To identify molecular mechanisms underlying lesion activity and halt, we analyzed genome-wide gene expression in rim and peri-lesional regions of chronic active and inactive MS lesions, as well as in control tissue. Gene clustering revealed patterns of gene expression specifically associated with MS and with the presumed, subsequent stages of lesion development. Next to genes involved in immune functions, we found regulation of novel genes in and around the rim of chronic active lesions, such as NPY, KANK4, NCAN, TKTL1, and ANO4. Of note, the presence of many foamy macrophages in active rims was accompanied by a congruent upregulation of genes related to lipid binding, such as MSR1, CD68, CXCL16, and OLR1, and lipid uptake, such as CHIT1, GPNMB, and CCL18. Except CCL18, these genes were already upregulated in regions around active MS lesions, showing that such lesions are indeed expanding. In vitro downregulation of the scavenger receptors MSR1 and CXCL16 reduced myelin uptake. In conclusion, this study provides the gene expression profile of different aspects of MS pathology and indicates that early demyelination, mediated by scavenger receptors, is already present in regions around active MS lesions. Genes involved in early demyelination events in regions surrounding chronic active MS lesions might be promising therapeutic targets to stop lesion expansion. PMID:29312322

Gene clustering revealed patterns of gene expression specifically associated with MS and with the presumed, subsequent stages of lesion development. Next to genes involved in immune functions, we found regulation of novel genes in and around the rim of chronic active lesions, such as NPY, KANK4, NCAN, TKTL1 , and ANO4 . Of note, the presence of many foamy macrophages in active rims was accompanied by a congruent upregulation of genes related to lipid binding, such as MSR1, CD68, CXCL16 , and OLR1 , and lipid uptake, such as CHIT1, GPNMB , and CCL18 . Except CCL18 , these genes were already upregulated in regions around active MS lesions, showing that such lesions are indeed expanding. In vitro downregulation of the scavenger receptors MSR1 and CXCL16 reduced myelin uptake. In conclusion, this study provides the gene expression profile of different aspects of MS pathology and indicates that early demyelination, mediated by scavenger receptors, is already present in regions around active MS lesions. Genes involved in early demyelination events in regions surrounding chronic active MS lesions might be promising therapeutic targets to stop lesion expansion.

Health literacy is a critically important skill that helps people become active participants in their health care. Multiple studies in the United States and across the world have documented the association of health literacy with multiple health outcomes. In particular, the elderly and many members of minority groups have been shown to have low levels of health literacy; the same groups are disproportionately affected by chronic illnesses. These twin burdens affect the people most in need of the skills and knowledge required for coping with chronic illnesses. Chronic disease self-management (CDSM) is a logical target for a general health literacy intervention. In an approach that spans across specific diseases, CDSM targets problems and skills needed to cope with issues such as fatigue, pain, stress, depression, sleep disturbance, and treatment adherence. In a previous study, we showed that a computer-delivered tailored information intervention targeting health literacy could improve treatment and adherence and be cost effective, but it is not clear that this same strategy will be effective in persons with low health literacy and multiple chronic conditions. The purpose of this study is to develop a computer-delivered mobile intervention that will provide individuals with chronic conditions the necessary information to cope with their conditions. In this project, we will complete a qualitative study on the status and needs of individuals with more than one chronic condition. Results of this study will be used to develop a mobile tailored information app that will address self-management challenges in the areas of pain, sleep, fatigue, depression, anger, stress, memory problems, and treatment adherence. The impact of the intervention on patient quality of life, patient-provider relationships, health literacy, and patient activation will be assessed. We will also explore the extent to which health literacy mediates important outcomes, such as health-related quality of life and health service utilization. We are currently completing the preliminary qualitative and usability studies that will inform the content and design of the intervention. We anticipate that the intervention will be complete in 2017, and the clinical trial of its efficacy will also commence in 2017. Results will provide evidence on the usefulness of a mobile tailored information app for improving health literacy, patient activation, health-related quality of life, and self-reported health in patients with multiple chronic conditions.

To contribute to the undecided question if a retrovirus of the human T-cell lymphotropic virus (HTLV) family may be involved in the development of multiple sclerosis (MS), we investigated by the polymerase chain reaction (PCR) the presence of HTLV-I and HTLV-II sequences in the peripheral blood mononuclear cell DNAs from 30 patients affected by MS and 15 by chronic progressive myelopathy. Moreover a control group of 14 blood donors was examined. All these patients were devoid of anti-HTLV-I antibody in the serum and cerebrospinal fluid at ELISA. For the PCR, primers and probes specific for the tax region common to HTLV-I and HTLV-II, for the pol region of HTLV-I, and for the pol region of HTLV-II were used. In spite of the high sensitivity of the technique used, the three groups of subjects were negative for HTLV-I and HTLV-II genomic sequences.

Introduction Non-communicable diseases are a growing global burden, and structured surveys can identify critical gaps to address this epidemic. In sub-Saharan Africa, there are very few well-tested survey instruments measuring population attributes related to non-communicable diseases. To meet this need, we have developed and validated the first instrument evaluating knowledge, attitudes and practices pertaining to chronic kidney disease in a Swahili-speaking population. Methods and Results Between December 2013 and June 2014, we conducted a four-stage, mixed-methods study among adults from the general population of northern Tanzania. In stage 1, the survey instrument was constructed in English by a group of cross-cultural experts from multiple disciplines and through content analysis of focus group discussions to ensure local significance. Following translation, in stage 2, we piloted the survey through cognitive and structured interviews, and in stage 3, in order to obtain initial evidence of reliability and construct validity, we recruited and then administered the instrument to a random sample of 606 adults. In stage 4, we conducted analyses to establish test-retest reliability and known-groups validity which was informed by thematic analysis of the qualitative data in stages 1 and 2. The final version consisted of 25 items divided into three conceptual domains: knowledge, attitudes and practices. Each item demonstrated excellent test-retest reliability with established content and construct validity. Conclusions We have developed a reliable and valid cross-cultural survey instrument designed to measure knowledge, attitudes and practices of chronic kidney disease in a Swahili-speaking population of Northern Tanzania. This instrument may be valuable for addressing gaps in non-communicable diseases care by understanding preferences regarding healthcare, formulating educational initiatives, and directing development of chronic disease management programs that incorporate chronic kidney disease across sub-Saharan Africa.

Morbidity and mortality from preventable, non-communicable chronic disease (NCD) threatens the health of our populations and our economies. The accumulation of vast amounts of scientific knowledge has done little to change this. New and innovative thinking is essential to foster new creative approaches that leverage and integrate evidence through the support of big data, technology, and design thinking. The purpose of this paper is to summarize the results of a consensus meeting on NCD prevention sponsored by the International Olympic Committee (IOC) in April, 2013. Within the context of advocacy for multifaceted systems change, the IOC's focus is to create solutions that gain traction within health care systems. The group of participants attending the meeting achieved consensus on a strategy for the prevention and management of chronic disease that includes the following: 1. Focus on behavioural change as the core component of all clinical programs for the prevention and management of chronic disease. 2. Establish actual centres to design, implement, study, and improve preventive programs for chronic disease. 3. Use human-centered design in the creation of prevention programs with an inclination to action, rapid prototyping and multiple iterations. 4. Extend the knowledge and skills of Sports and Exercise Medicine (SEM) professionals to build new programs for the prevention and treatment of chronic disease focused on physical activity, diet and lifestyle. 5. Mobilize resources and leverage networks to scale and distribute programs of prevention. True innovation lies in the ability to align thinking around these core strategies to ensure successful implementation of NCD prevention and management programs within health care. The IOC and SEM community are in an ideal position to lead this disruptive change. The outcome of the consensus meeting was the creation of the IOC Non-Communicable Diseases ad-hoc Working Group charged with the responsibility of moving this agenda forward.

Chronic obstructive pulmonary disease (COPD) is one of the most common causes of readmission at Veterans Affairs (VA) hospitals. Previous studies demonstrate worse outcomes for veterans with multisystem health care, though the impact of non-VA care on COPD readmissions is unknown. To examine the association of use of non-VA outpatient care with 30-day readmission and 30-day follow-up among veterans admitted to the VA for COPD. This is a retrospective cohort study using VA administrative data and Medicare claims. In total, 20,472 Medicare-eligible veterans who were admitted to VA hospitals for COPD during October 1, 2008 and September 30, 2011. We identified the source of outpatient care during the year before the index hospitalization as VA-only, dual-care (VA and Medicare), and Medicare-only. Outcomes of interest included any-cause 30-day readmission, COPD-specific 30-day readmission and follow-up visit within 30 days of discharge. We used mixed-effects logistic regression, controlling for baseline severity of illness, to examine the association between non-VA care and postdischarge outcomes. There was no association between non-VA care and any-cause readmission. We did identify an increased COPD-specific readmission risk with both dual-care [odds ratio (OR)=1.20; 95% confidence interval (CI), 1.02-1.40] and Medicare-only (OR=1.41; 95% CI, 1.15-1.75). Medicare-only outpatient care was also associated with significantly lower rates of follow-up (OR=0.81; 95% CI, 0.72-0.91). Differences in disease-specific readmission risk may reflect differences in disease management between VA and non-VA providers. Further research is needed to understand how multisystem care affects coordination and other measures of quality for veterans with COPD.

Beryllium has multiple industrial applications, but its manufacture is associated with a serious occupational risk of developing chronic inflammation in the lungs known as berylliosis, or chronic beryllium disease. Although the Be 2+ -induced abnormal immune responses have recently been linked to a specific MHC-II allele, the nature of long-lasting granulomas is not fully understood. Here we show that Be 2+ binds with a micromolar affinity to phosphatidylserine (PS), the major surface marker of apoptotic cells. Isothermal titration calorimetry indicates that, like that of Ca 2+ , binding of Be 2+ to PS liposomes is largely entropically driven, likely by massive desolvation. Be 2+ exerts a compacting effect on PS monolayers, suggesting cross-linking through coordination by both phosphates and carboxyls in multiple configurations, which were visualized in molecular dynamics simulations. Electrostatic modification of PS membranes by Be 2+ includes complete neutralization of surface charges at ∼30 μM, accompanied by an increase in the boundary dipole potential. The data suggest that Be 2+ can displace Ca 2+ from the surface of PS, and being coordinated in a tight shell of four oxygens, it can mask headgroups from Ca 2+ -mediated recognition by PS receptors. Indeed, 48 μM Be 2+ added to IC-21 cultured macrophages specifically suppresses binding and engulfment of PS-coated silica beads or aged erythrocytes. We propose that Be 2+ adsorption at the surface of apoptotic cells may potentially prevent normal phagocytosis, thus causing accumulation of secondary necrotic foci and the resulting chronic inflammation.

Abstract Chronic diseases in most cases belong to the category of non-communicable diseases (NCDs), which are the main cause of mortality globally. Cardiovascular diseases, diabetes, chronic obstructive pulmonary disease and cancer are the four NCDs responsible for 82% of NCD deaths. Prevention of NCDs implies health promotion activities that encourage healthy lifestyle and limit the initial onset of chronic diseases. Prevention also includes early detection activities, such as screening at-risk populations, as well as strategies for appropriate management of existing diseases and related complications. Early intervention, reducing morbidity and mortality rates could be an appealing idea for patients, physicians and governmental institutions but could also cause harm. Healthcare is undergoing profound changes, and the role of technology in diagnostics and management of chronic diseases in primary healthcare (PHC) is increasing remarkably. However, studies show that the standards of care for chronic diseases and preventive care are met by less than 50%. We still lack clear standards for patients with multiple chronic diseases. The applicability of a single evidence-based guideline to multimorbid patients is limited and can be problematic. Well-designed PHC studies focusing on the impact of medical interventions on morbidity, mortality and quality of life in the fields of early diagnosis, early treatment and multimorbidity are still needed.

Background Health information technology (HIT) is utilized by people with different chronic conditions such as diabetes and hypertension. However, there has been no comparison of HIT use between persons without a chronic condition, with one chronic condition, and multiple (≥2) chronic conditions (MCCs). Objective The aim of the study was to assess the difference in HIT use between persons without a chronic condition, with one chronic condition, and with MCCs, to describe the characteristics of HIT use among those with chronic conditions and to identify the predictors of HIT use of the persons with one chronic condition and MCCs. Methods A secondary data analysis was conducted in spring 2017 using the National Health Interview Survey (NHIS) 2012 Family Core and Sample Adult Core datasets that yielded 34,525 respondents aged 18 years and older. Measures included overall HIT use (ie, any use of the following five HIT on the Internet: seeking health information, ordering prescription, making appointment, emailing health provider, and using health chat groups), as well as sociodemographic and health-related characteristics. Sociodemographic and health characteristics were compared between HIT users and nonusers among those who reported having at least one chronic condition using chi-square tests. Independent predictors of HIT use were identified using multiple logistic regression analyses for those with one chronic condition, with MCCs, and without a chronic condition. Analyses were weighted and performed at significance level of .005. Results In 2012, adults with one health chronic condition (raw count 4147/8551, weighted percentage 48.54%) was significantly higher than among those with MCCs (3816/9637, 39.55%) and those with none of chronic condition (7254/16,337, 44.40%, P<.001). Seeking health information was the most prevalent HIT use. Chi-square tests revealed that among adults with chronic conditions, those who used HIT were significantly different from their counterpart peers who did not use HIT in terms of sociodemographic and health characteristics (P<.001). Overall, the significant factors related to HIT use were similar among the adults with one chronic condition, with MCCs, or without a chronic condition: younger age, female sex, non-Hispanic white, higher education level, and higher income level were shown to be positively related to the HIT use. Conclusions This study provides a snapshot of HIT use among those with chronic conditions and potential factors related to such use. Clinical care and public health communication efforts attempting to leverage more HIT use should acknowledge differential HIT usage as identified in this study to better address communication inequalities and persistent disparities in socioeconomic status.

Chronic inflammatory conditions, such as psoriasis, may pose an increased risk of cancer due to impaired immunosurveillance resulting from chronic inflammation and immunosuppressive medications. To compare the risk of non-melanoma skin cancer (NMSC) in a retrospective cohort of 72,739 psoriasis patients and 25,956 non-dermatological patients. A record linkage was performed for data on hospitalizations, and the occurrence of NMSC was compared by computing the relative risk (RR) and modelled using multiple logistic regression. Overall, the occurrence of NMSC was 9.6‰ (95% CI: 8.9-10.3‰) in psoriasis patients and 19.6‰ (95% CI: 18.0-21.4‰) in non-dermatological patients (RR = 0.49; 95% CI: 0.44-0.55). The simultaneous adjustment for gender, age, and phototherapy yielded a RR of 0.84 (95% CI: 0.75-0.95). With regards to phototherapy, the occurrence of NMSC was significantly higher among psoriasis patients who underwent phototherapy relative to those who did not (27.0‰ vs. 9.3‰). In this large retrospective study, we found that patients with psoriasis had a 16% lower probability of having NMSC when compared to a group of non-dermatological patients. Further studies, preferably with a prospective longitudinal design to collect more precise data, are needed to corroborate our findings.

Adherence to chronic disease management is critical to achieving improved health outcomes, quality of life, and cost-effective health care. As the burden of chronic diseases continues to grow globally, so does the impact of non-adherence. Mobile technologies are increasingly being used in health care and public health practice (mHealth) for patient communication, monitoring, and education, and to facilitate adherence to chronic diseases management. We conducted a systematic review of the literature to evaluate the effectiveness of mHealth in supporting the adherence of patients to chronic diseases management ("mAdherence"), and the usability, feasibility, and acceptability of mAdherence tools and platforms in chronic disease management among patients and health care providers. We searched PubMed, Embase, and EBSCO databases for studies that assessed the role of mAdherence in chronic disease management of diabetes mellitus, cardiovascular disease, and chronic lung diseases from 1980 through May 2014. Outcomes of interest included effect of mHealth on patient adherence to chronic diseases management, disease-specific clinical outcomes after intervention, and the usability, feasibility, and acceptability of mAdherence tools and platforms in chronic disease management among target end-users. In all, 107 articles met all inclusion criteria. Short message service was the most commonly used mAdherence tool in 40.2% (43/107) of studies. Usability, feasibility, and acceptability or patient preferences for mAdherence interventions were assessed in 57.9% (62/107) of studies and found to be generally high. A total of 27 studies employed randomized controlled trial (RCT) methods to assess impact on adherence behaviors, and significant improvements were observed in 15 of those studies (56%). Of the 41 RCTs that measured effects on disease-specific clinical outcomes, significant improvements between groups were reported in 16 studies (39%). There is potential for mHealth tools to better facilitate adherence to chronic disease management, but the evidence supporting its current effectiveness is mixed. Further research should focus on understanding and improving how mHealth tools can overcome specific barriers to adherence.

The gammaretroviruses xenotropic murine leukemia virus (MLV)-related virus (XMRV) and MLV have been reported to be more prevalent in plasma and peripheral blood mononuclear cells of chronic fatigue syndrome (CFS) patients than in healthy controls. Here, we report the complex analysis of whole blood and plasma samples from 58 CFS patients and 57 controls from Canada for the presence of XMRV/MLV nucleic acids, infectious virus, and XMRV/MLV-specific antibodies. Multiple techniques were employed, including nested and qRT-PCR, cell culture, and immunoblotting. We found no evidence of XMRV or MLV in humans and conclude that CFS is not associated with these gammaretroviruses. PMID:22114717

This study uses a stress-coping-support framework to examine the predictors of caregiver burden with a sample of 103 lower social class family caregivers of persons with chronic mental illness. Results of multiple regression analyses show that the greater the frequency of client behavioral symptoms and the lower the amount of perceived support from family members, the higher the level of overall caregiver burden. Examination of the predictors of specific types of burden-family disruption, stigma, strain, and dependency-reveal that different constellations of variables predict different types of burden. The need for mental health agencies to address caregiver and client concerns is addressed. Implications are presented for practice and future research.

Compared with healthy controls, dogs with chronic kidney disease (PÄ0·0008), carcinoma (PÄ0·0072) and lymphoma (PÄ0·0008) had elevated serum and urine NGAL and urine NGAL-to-creatinine ratio. Serum and urine NGAL was not significantly different between dogs with chronic kidney disease, carcinoma or lymphoma (Pê0·12). In dogs with non-progressive chronic kidney disease, NGAL concentrations did not change significantly over the 6-month study period. NGAL can be elevated by chronic kidney disease and neoplasia, compared with healthy controls. Further research is needed to determine if uNGAL or uNGAL-to-creatinine ratio is more specific than serum levels to detect chronic kidney disease. © 2016 British Small Animal Veterinary Association.

The present study was designed to assess the effect of sublethal concentrations of electoplating industry effluent (EIE) on the non-specific and specific immune responses in the freshwater fish, Cyprinus carpio. Sublethal concentrations of electroplating industry effluent such as 0.004, 0.007, 0.010 and 0.013% were chosen based on the LC 50 values. Experimental fish were exposed to these sublethal concentrations of EIE for 28 days. After 7, 14, 21 and 28 days of treatment, non-specific immune response by serum lysozyme activity, myeloperoxidase activity and antiprotease activity and specific immune response by antibody response to Aeromonas hydrophila using bacterial agglutination assay and ELISA were assessed. The results showed that chronic exposure of fish to 0.004, 0.007, 0.010 and 0.013% EIE, dose-dependently decreased the non-specific and specific immune responses on all the days tested compared to control fish whereas statistically significant suppressive effects were observed in fish exposed to 0.013% of EIE on all activities tested.

Previously rare A2ML1 variants were identified to confer otitis media susceptibility in an indigenous Filipino community and in otitis-prone US children. The goal of this study is to describe differences in the middle ear microbiome between carriers and non-carriers of an A2ML1 duplication variant that increases risk for chronic otitis media among indigenous Filipinos with poor health care access. Ear swabs were obtained from 16 indigenous Filipino individuals with chronic otitis media, of whom 11 carry the A2ML1 duplication variant. Ear swabs were submitted for 16S rRNA gene sequencing. Genotype-based differences in microbial richness, structure, and composition were identified, but were not statistically significant. Taxonomic analysis revealed that the relative abundance of the phyla Fusobacteria and Bacteroidetes, and genus Fusobacterium were nominally increased in carriers compared to non-carriers, but were non-significant after correction for multiple testing. We also detected rare bacteria including Oligella that was reported only once in the middle ear. These findings suggest that A2ML1-related otitis media susceptibility may be mediated by changes in the middle ear microbiome. Knowledge of middle ear microbial profiles according to genetic background can be potentially useful for therapeutic and prophylactic interventions for otitis media and can guide public health interventions towards decreasing otitis media prevalence within the indigenous Filipino community.

The factors determining the functional avidity and its relationship with the broad heterogeneity of antiviral T cell responses remain partially understood. We investigated HIV-specific CD8 T cell responses in 85 patients with primary HIV infection (PHI) or chronic (progressive and non-progressive) infection. The functional avidity of HIV-specific CD8 T cells was not different between patients with progressive and non-progressive chronic infection. However, it was significantly lower in PHI patients at the time of diagnosis of acute infection and after control of virus replication following one year of successful antiretroviral therapy. High-avidity HIV-specific CD8 T cells expressed lower levels of CD27 and CD28 and were enriched in cells with an exhausted phenotype, i.e. co-expressing PD-1/2B4/CD160. Of note, a significant increase in the functional avidity of HIV-specific CD8 T cells occurred in early-treated PHI patients experiencing a virus rebound after spontaneous treatment interruption. This increase in functional avidity was associated with the accumulation of PD-1/2B4/CD160 positive cells, loss of polyfunctionality and increased TCR renewal. The increased TCR renewal may provide the mechanistic basis for the generation of high-avidity HIV-specific CD8 T cells. These results provide insights on the relationships between functional avidity, viremia, T-cell exhaustion and TCR renewal of antiviral CD8 T cell responses. PMID:23853580

Patterns of evolution at the gametophytic self-incompatibility Sorbus aucuparia (Pyrinae) S pollen genes support the non-self recognition by multiple factors model

S-RNase-based gametophytic self-incompatibility evolved once before the split of the Asteridae and Rosidae. In Prunus (tribe Amygdaloideae of Rosaceae), the self-incompatibility S-pollen is a single F-box gene that presents the expected evolutionary signatures. In Malus and Pyrus (subtribe Pyrinae of Rosaceae), however, clusters of F-box genes (called SFBBs) have been described that are expressed in pollen only and are linked to the S-RNase gene. Although polymorphic, SFBB genes present levels of diversity lower than those of the S-RNase gene. They have been suggested as putative S-pollen genes, in a system of non-self recognition by multiple factors. Subsets of allelic products of the different SFBB genes interact with non-self S-RNases, marking them for degradation, and allowing compatible pollinations. This study performed a detailed characterization of SFBB genes in Sorbus aucuparia (Pyrinae) to address three predictions of the non-self recognition by multiple factors model. As predicted, the number of SFBB genes was large to account for the many S-RNase specificities. Secondly, like the S-RNase gene, the SFBB genes were old. Thirdly, amino acids under positive selection—those that could be involved in specificity determination—were identified when intra-haplotype SFBB genes were analysed using codon models. Overall, the findings reported here support the non-self recognition by multiple factors model. PMID:23606363

Acute-on-chronic liver failure (ACLF) is characterized by a rapid progression to multiple organ failure and is associated with a very high mortality rate of 50-90%. Novel therapies are being investigated such as Erythropoietin (EPO). The aim of this prospective cohort study was to analyse the value of EPO in predicting prognosis and determine which patients may benefit most from EPO therapy. According to the EASL-CLIF criteria, 104 consecutive patients were diagnosed with ACLF, and separated into two groups based on the type of insult: bleeding (Group A=31) or non-bleeding (Group B=73). In addition to a complete biochemical work-up and calculation of relevant prognostic scores, levels of EPO were measured on admission and correlated to the type of insult and final outcome. Fifteen patients from Group A (mean age 60.32+/-9.29 years) had a lethal outcome and higher values of EPO on admission (319.26+/-326.58 mIU/ml) (p<0.005), compared to the 37 patients from Group B (mean age 59.9+/-10.19 years) with EPO levels at admission of 29.88+/-34.6 mIU/mL. In Group B, a cut-off EPO value of 30.65 mIU/mL had a sensitivity of 87.5% and a specificity 57.4% in predicting lethal outcome with an AUROC of 0.823. In Group A, a cut-off value of 229.95 mlU/mL had a sensitivity and specificity of 53.3% and 92.7%, respectively. The AUROC for this cut-off was 0.847. Erythropoietin is superior to the standard prognostic scores in predicting 28-day mortality. Lower levels of EPO were detected in patients without bleeding as an insult indicating a possible therapeutic benefit in these patients.

In multiple sclerosis, remyelination becomes limited after repeated or prolonged episodes of demyelination. To test the effect of platelet-derived growth factor-A (PDGF-A) in recovery from chronic demyelination we induced corpus callosum demyelination using cuprizone treatment in hPDGF-A transgenic (tg) mice with the human PDGF-A gene under control of an astrocyte-specific promoter. After chronic demyelination and removal of cuprizone from the diet, remyelination and oligodendrocyte density improved significantly in hPDGF-A tg mice compared with wild-type mice. In hPDGF-A tg mice, oligodendrocyte progenitor density and proliferation values were increased in the corpus callosum during acute demyelination but not during chronic demyelination or the subsequent recovery period, compared with hPDGF-A tg mice without cuprizone or to treatment-matched wild-type mice. Proliferation within the subventricular zone and subcallosal zone was elevated throughout cuprizone treatment but was not different between hPDGF-A tg and wild-type mice. Importantly, hPDGF-A tg mice had reduced apoptosis in the corpus callosum during the recovery period after chronic demyelination. Therefore, PDGF-A may support oligodendrocyte generation and survival to promote remyelination of chronic lesions. Furthermore, preventing oligodendrocyte apoptosis may be important not only during active demyelination but also for supporting the generation of new oligodendrocytes to remyelinate chronic lesions.

To examine relationships between a mother's stress-related conditions and parenting attitudes and their children's asthmatic status. 274 mothers of an asthmatic child 2 to 12 years old completed a questionnaire including questions about their chronic stress/coping behaviors (the "Stress Inventory"), parenting attitudes (the "Ta-ken Diagnostic Test for Parent-Child Relationship, Parent Form"), and their children's disease status. One year later, a follow-up questionnaire was mailed to the mothers that included questions on the child's disease status. 223 mothers (81%) responded to the follow-up survey. After controlling for non-psychosocial factors including disease severity at baseline, multiple linear regression analysis followed by multiple logistic regression analysis found chronic irritation/anger and emotional suppression to be aggravating factors for children aged < 7 years; for children aged 7 and over, the mothers' egocentric behavior was a mitigating factor while interference was an aggravating factor. Different types of parental stress/coping behaviors and parenting styles may differently predict their children's asthmatic status, and such associations may change as children grow.

The diagnosis of chronic pancreatitis remains challenging in early stages of the disease. This report defines the diagnostic criteria useful in the assessment of patients with suspected and established chronic pancreatitis. All current diagnostic procedures are reviewed and evidence based statements are provided about their utility and limitations. Diagnostic criteria for chronic pancreatitis are classified as definitive, probable or insufficient evidence. A diagnostic (STEP-wise; S-survey, T-tomography, E-endoscopy and P-pancreas function testing) algorithm is proposed that proceeds from a non-invasive to a more invasive approach. This algorithm maximizes specificity (low false positive rate) in subjects with chronic abdominal pain and equivocal imaging changes. Futhermore, a nomenclature is suggested to further characterize patients with established chronic pancreatitis based on TIGAR-O (T-toxic, I-idiopathic, G-genetic, A- autoimmune, R-recurrent and O-obstructive) etiology, gland morphology (Cambridge criteria) and physiologic state (exocrine, endocrine function) for uniformity across future multi-center research collaborations. This guideline will serve as a baseline manuscript that will be modified as new evidence becomes available and our knowledge of chronic pancreatitis improves. PMID:25333398

Given the wide variations in prevalence of chronic obstructive pulmonary disease observed between populations with similar levels of exposure to tobacco smoke, we aimed to investigate the possibility of variations in prevalence of chronic bronchitis (CB) between two geographically distinct smoking populations in rural Karnataka, India. The Burden of Obstructive Lung Disease (BOLD) questionnaire was administered to all men aged >30 years in a cross-sectional survey. The χ(2) and Fisher's exact tests were used to compare CB prevalence in the two populations. Logistic regression was used to analyse the impact of multiple variables on the occurrence of CB. Two samples of 2322 and 2182 subjects were included in the study. In non-smokers, CB prevalence did not differ between the populations. However, it was significantly different between smoking populations (44.79% vs. 2.13%, P < 0.0001). Logistic regression indicated that, in addition to smoking, region, age, occupational dust exposure and type of house were associated with higher likelihood of CB. An interaction between smoking and area of residence was found (P < 0.001) and appeared to explain the effect of region (without interaction). A significant difference in CB prevalence was observed between male populations from two areas of Karnataka state, including when stratified by smoking status. No significant difference was observed between non-smokers.

BACKGROUND—Several retrospective and prospective studies report an increased prevalence of non-organ-specific autoantibodies (NOSAs) in patients with hepatitis C virus (HCV) related chronic liver disease (CLD). Some of the data so far available are controversial and the true prevalence of NOSAs in the general population is still not known.
AIM—To explore the prevalence of NOSAs, their relation to different HCV genotypes, and the presence and severity of CLD in the general population of Northern Italy.
PATIENTS—All 226 anti-HCV positive and 87 hepatitis B surface antigen (HBsAg) positive patients of the Dionysos cohort study were analysed and compared with sex and age matched cases (226) negative for both anti-HCV antibody and HBsAg selected from the same cohort.
METHODS—Sera tested for the presence of NOSAs (anti-nuclear antibody (ANA), anti-smooth muscle antibody (SMA), and anti-liver/kidney microsomes type 1 antibody (LKM1)) were screened by indirect immunofluorescence at a 1:40 serum dilution. HCV RNA and HCV genotypes were also determined by nested polymerase chain reaction (PCR) of the 5' non-coding region and by PCR amplification of the core region with type specific primers.
RESULTS—The overall prevalence of NOSA reactivity was significantly higher in anti-HCV positive subjects than in both normal and pathological controls (25% v 6% and 7% respectively, p<0.05). ANA, SMA, and LKM1 occurred in 16, 10, and 1.3% of cases respectively. No specific association between NOSAs and a specific HCV genotype was found. NOSAs were found more often associated with more than one genotype (35.7%) and with untypable genotypes (34.6%), although the association was not statistically significant. NOSAs were associated with HCV RNA and CLD but not with the presence of cirrhosis and/or hepatocellular carcinoma. On univariate analysis, NOSA reactivity was independently associated with abnormal alanine aminotransferase (p<0.01) and γ-glutamyltranspeptidase levels (p<0.05). The risk for the presence of NOSAs was 5.1 times higher in anti-HCV subjects than in controls.
CONCLUSIONS—In the general population the prevalence of NOSAs is higher in anti-HCV positive subjects than in normal or disease controls. Moreover NOSAs are associated with CLD and with a more active disease in terms of alanine aminotransferase activity.

The profile and progress of neglected and abused children in long-term foster care.

2009-07-01

This study compared the profile of neglected and abused children in the Australian foster care system as well as differences between maltreatment types in relation to parental contact, reunification and psychosocial progress in care. The case files of 235 children entering foster care were examined and their social workers were administered standardised questionnaires at the point of intake. All measures were repeated for those remaining in care 1 year and then again 2 years later. Neglected children were younger than non-neglected children, more likely to have a physical or mental disability, more likely to experience multiple forms of maltreatment and less likely to pose conduct problems for carers. Neglected children were more likely than non-neglected children to experience a decline in parental contact over time, and were less likely to be reunified with their families of origin. There was minimal difference between neglected and non-neglected in their psychosocial progress while in care. Aboriginal children were more likely to be reunified than non-Aboriginal children when neglect was attributable to transient factors (parental incapacity) but the reverse was true for non-neglected children. The fact that neglected children more often require a second form of maltreatment before being removed from home suggests that children's services workers are less inclined to remove children for neglect than for other forms of maltreatment. As a consequence, those neglected children who are in care tend to come from more dysfunctional families than non-neglected children do, as evidenced by the relatively poorer parental contact and reunification results of neglected children. Neglected children differ systematically from non-neglected children and suffer relative disadvantage in relation to multiple forms of maltreatment, parental contact, and reunification. The fact that declines in parental contact among neglected children in care occurred only when indirect contact was provided suggests that, wherever possible, care plans should include face-to-face visits and overnight stays rather than being restricted to less direct forms of contact. The difference in the success of reunification according to type of neglect (chronic or transient) also suggests that parental intervention programs need to focus their efforts on chronic factors rather than transient parental factors.

Hepatitis C virus (HCV)-specific CD4+ and CD8+ T cells are key to successful viral clearance in HCV disease. Accumulation of exhausted HCV-specific T cells during chronic infection results in considerable loss of protective functional immune responses. The role of T-cell exhaustion in chronic HCV disease remains poorly understood. Here, we studied the frequency of HCV peptide-stimulated T cells expressing negative immune checkpoints (PD-1, CTLA-4, TRAIL, TIM-3 and BTLA) by flow cytometry, and measured the levels of Th1/Th2/Th17 cytokines secreted by T cells by a commercial Multi-Analyte ELISArray™ following in vitro stimulation of T cells using HCV peptides and phytohemagglutinin (PHA). HCV peptide-stimulated CD4+ and CD8+ T cells of chronic HCV (CHC) patients showed significant increase of CTLA-4. Furthermore, HCV peptide-stimulated CD4+ T cells of CHC patients also displayed relatively higher levels of PD-1 and TRAIL, whereas TIM-3 was up-regulated on HCV peptide-stimulated CD8+ T cells. Whereas the levels of IL-10 and TGF-β1 were significantly increased, the levels of pro-inflammatory cytokines IL-2, TNF-α, IL-17A and IL-6 were markedly decreased in the T cell cultures of CHC patients. Chronic HCV infection results in functional exhaustion of CD4+ and CD8+ T cells likely contributing to viral persistence. Copyright © 2016 Elsevier Inc. All rights reserved.

Unpredictable chronic mild stress differentially impairs social and contextual discrimination learning in two inbred mouse strains

2017-01-01

Alterations in the social and cognitive domain are considered important indicators for increased disability in many stress-related disorders. Similar impairments have been observed in rodents chronically exposed to stress, mimicking potential endophenotypes of stress-related psychopathologies such as major depression disorder (MDD), anxiety, conduct disorder, and posttraumatic stress disorder (PTSD). Data from numerous studies suggest that deficient plasticity mechanisms in hippocampus (HC) and prefrontal cortex (PFC) might underlie these social and cognitive deficits. Specifically, stress-induced deficiencies in neural plasticity have been associated with a hypodopaminergic state and reduced neural plasticity persistence. Here we assessed the effects of unpredictable chronic mild stress (UCMS) on exploratory, social and cognitive behavior of females of two inbred mouse strains (C57BL/6J and DBA/2J) that differ in their dopaminergic profile. Exposure to chronic stress resulted in impaired circadian rhythmicity, sociability and social cognition in both inbred strains, but differentially affected activity patterns and contextual discrimination performance. These stress-induced behavioral impairments were accompanied by reduced expression levels of brain derived neurotrophic factor (BDNF) in the prefrontal cortex. The strain-specific cognitive impairment was coexistent with enhanced plasma corticosterone levels and reduced expression of genes related to dopamine signaling in hippocampus. These results underline the importance of assessing different strains with multiple test batteries to elucidate the neural and genetic basis of social and cognitive impairments related to chronic stress.

The aim of this study is to find the association of chronic disease prevalence (CDP) with suicide-related ideation (SI) and suicide attempt (SA) and to determine the combined effect of CDP and quality of life (QoL) with SI or SA. This was a cross-sectional study. The data were collected from the nationally representative Korea National Health and Nutrition Examination Survey IV and V (2007-2012). For the analysis, a total of 35,075 adult participants were selected as the final sample, which included 5773 participants with SI and 331 with SA. Multiple logistic regression models were used to examine the odds ratio after adjusting for age, sex, marital status, education, occupation, and household income. SI was positively associated with selected CDP, such as cardiovascular disease (CVD), stroke, ischemic heart disease (IHD), cancer, diabetes, renal failure, and depression, except hypertension. Subjects with CVD, IHD, renal failure, and depression were found likely to have increased odds for SA as compared to non-SA controls. Lower QoL strongly affected SI and SA. Furthermore, the likelihood of SI increased for depressed and cancer subjects who had low QoL in comparison to subjects with high QoL and without chronic disease. Similarly, statistically, significant interaction was observed between lower QoL and depression in relation to SA compared to non-SA controls. These data suggest that suicide-related behavior could be predicted by the prevalence of chronic disease and low QoL.

Chronic low back pain is associated with lumbar extensor deconditioning. This may contribute to decreased neuromuscular control and balance. However, balance is also influenced by the hip musculature. Thus, the purpose of this study was to examine balance in both asymptomatic participants and those with chronic low back pain, and to examine the relationships among balance, lumbar extension strength, trunk extension endurance, and pain. Forty three asymptomatic participants and 21 participants with non-specific chronic low back pain underwent balance testing using the Star Excursion Balance Test, lumbar extension strength, trunk extension endurance, and pain using a visual analogue scale. Significant correlations were found between lumbar extension strength and Star Excursion Balance Test scores in the chronic low back pain group (r = 0.439-0.615) and in the asymptomatic group (r = 0.309-0.411). Correlations in the chronic low back pain group were consistently found in posterior directions. Lumbar extension strength explained ~19.3% to ~37.8% of the variance in Star Excursion Balance Test scores for the chronic low back pain group and ~9.5% to ~16.9% for the asymptomatic group. These results suggest that the lumbar extensors may be an important factor in determining the motor control dysfunctions, such as limited balance, that arise in chronic low back pain. As such, specific strengthening of this musculature may be an approach to aid in reversing these dysfunctions. Copyright © 2018 Elsevier Ltd. All rights reserved.

Using multiple decrement models to estimate risk and morbidity from specific AIDS illnesses. Multicenter AIDS Cohort Study (MACS).

PubMed

Hoover, D R; Peng, Y; Saah, A J; Detels, R R; Day, R S; Phair, J P

A simple non-parametric approach is developed to simultaneously estimate net incidence and morbidity time from specific AIDS illnesses in populations at high risk for death from these illnesses and other causes. The disease-death process has four-stages that can be recast as two sandwiching three-state multiple decrement processes. Non-parametric estimation of net incidence and morbidity time with error bounds are achieved from these sandwiching models through modification of methods from Aalen and Greenwood, and bootstrapping. An application to immunosuppressed HIV-1 infected homosexual men reveals that cytomegalovirus disease, Kaposi's sarcoma and Pneumocystis pneumonia are likely to occur and cause significant morbidity time.

Targeting of non-dominant antigens as a vaccine strategy to broaden T-cell responses during chronic viral infection.

2015-01-01

In this study, we compared adenoviral vaccine vectors with the capacity to induce equally potent immune responses against non-dominant and immunodominant epitopes of murine lymphocytic choriomeningitis virus (LCMV). Our results demonstrate that vaccination targeting non-dominant epitopes facilitates potent virus-induced T-cell responses against immunodominant epitopes during subsequent challenge with highly invasive virus. In contrast, when an immunodominant epitope was included in the vaccine, the T-cell response associated with viral challenge remained focussed on that epitope. Early after challenge with live virus, the CD8+ T cells specific for vaccine-encoded epitopes, displayed a phenotype typically associated with prolonged/persistent antigenic stimulation marked by high levels of KLRG-1, as compared to T cells reacting to epitopes not included in the vaccine. Notably, this association was lost over time in T cells specific for the dominant T cell epitopes, and these cells were fully capable of expanding in response to a new viral challenge. Overall, our data suggests a potential for broadening of the antiviral CD8+ T-cell response by selecting non-dominant antigens to be targeted by vaccination. In addition, our findings suggest that prior adenoviral vaccination is not likely to negatively impact the long-term and protective immune response induced and maintained by a vaccine-attenuated chronic viral infection.

The aim of this review was to identify, appraise and synthesise the outcome measures used to assess self-management in patients with chronic pain. Medline, Embase, CINAHL, PsycINFO, the Cochrane Library and Google Scholar were searched to identify quantitative measures used within randomised or non-randomised clinical trials to assess self-management in adults (≥18 years) with chronic pain. 25 RCTs published between 1998 and 2016 were included in this review. Studies included patients with chronic pain, hip/knee osteoarthritis, rheumatoid arthritis, chronic low back pain, fibromyalgia and chronic fatigue syndrome. Included studies utilised 14 different measures assessing a variety of constructs including self-efficacy (n = 19), coping (n = 4), empowerment (n = 2), pain attitude and management (n = 3), self-care (n = 1), role behaviour (n = 1) and multiple constructs of self-management (n = 1). The Chronic Pain Coping Inventory (CPCI) and Health Education Impact Questionnaire (heiQ) cover different self-management related constructs across the physical, mental and social health domains. The review identified 14 measures used as proxy measure to assess self-management in patients with chronic pain. These measures have good content and construct validity, and internal consistency. However additional research is required to develop their reliability, responsiveness and interpretability. Multi-constructs measures (CPCI, heiQ) are suitable for assessing self-management.

Chronic active Epstein-Barr virus (CAEBV) infection is characterized by persistent infectious mononucleosis-like symptoms, an unusual pattern of Epstein-Barr virus (EBV) antibodies, detection of the EBV genome in affected tissues or peripheral blood, and chronic illness that cannot be attributed to any other known disease. This is the first reported Korean case of an immunocompetent adult with CAEBV-associated interstitial pneumonitis. A 28-year-old female was admitted with a fever that persisted for 3 weeks. She had multiple lymphadenopathy, hepatosplenomegaly, pancytopenia, and elevated serum aminotransferase levels. Serology for antibodies was positive and chest computed tomography showed diffuse ground glass opacities in both lungs. Histopathology of the lung tissue showed lymphocyte infiltration, and EBV DNA was detected in those lymphocytes using in situ hybridization with an EBV-encoded RNA probe. After 1 month of hospitalization, she improved without specific treatment. PMID:22205850

Spinal Manipulation (SM) has been purported to decrease pain and improve function in subjects with non-specific neck pain. Previous research has investigated which individuals with non-specific neck pain will be more likely to benefit from SM. It has not yet been proven whether or not the effectiveness of thoracic SM depends on the specific technique being used. This double-blind randomized trial has compared the short-term effects of two thoracic SM maneuvers in subjects with chronic non-specific neck pain. Sixty participants were distributed randomly into two groups. One group received the Dog technique (n = 30), with the subject in supine position, and the other group underwent the Toggle-Recoil technique (n = 30), with the participant lying prone, T4 being the targeted area in both cases. Evaluations were made of self-reported neck pain (Visual Analogue Scale); neck mobility (Cervical Range of Motion); and pressure pain threshold at the cervical and thoracic levels (C4 and T4 spinous process) and over the site described for location of tense bands of the upper trapezius muscle. Measurements were taken before intervention, immediately afterward, and 20 min later. Both maneuvers improved neck mobility and mechanosensitivity and reduced pain in the short term. No major or clinical differences were found between the groups. In the between-groups comparison slightly better results were observed in the Toggle-Recoil group only for cervical extension (p = 0.009), right lateral flexion (p = 0.004) and left rotation (p < 0.05).

Children of mentally ill parents are known as a high-risk population for the development of psychological disturbances. In this study, the psychiatric diagnoses, the severity and chronicity and the comorbidity of a parental mental illness as well as the non-specific parameters were examined in terms of their influence on the children's mental health. n = 62 children of psychiatric inpatients were examined regarding their psychic symptomatology, assessed with the CBCL-Parent Report Form. The psychiatric ICD-10 diagnoses and comorbidities as well as the severity (CGI) of the mentally ill parents were collected from psychiatric assessment forms. Children of parents with personality disorders (PD) are evaluated as highly affected by their parents, regardless of whether the PD is the primary or the comorbid diagnosis. Children of parents suffering from addictive disorders are seen as the least affected by their parents. Overall, children of parents with multiple diagnoses tend to be rated as more affected. Severity of illness and chronicity do not have a considerable impact on the children's development of mental health problems. Strikingly, children with a high length of exposure to a parental illness are psychologically less affected than children with shorter times of exposure. Thus, children possibly acquire effective coping mechanisms with increasing time of exposure. The results reveal the necessity of preventive programmes, especially in case of personality disorders. In addition the necessity for external assessment of the children becomes clear, especially in those cases where the parents exhibit a poor acceptance of their disease. © Georg Thieme Verlag KG Stuttgart · New York.

Intensive group training using principles of graded activity has been proven to be effective in occupational care for workers with chronic low back pain. Objective of the study was to compare the effects of an intensive group training protocol aimed at returning to normal daily activities and guideline physiotherapy for primary care patients with non-specific chronic low back pain. The study was designed as pragmatic randomised controlled trial with a setup of 105 primary care physiotherapists in 49 practices and 114 patients with non-specific low back pain of more than 12 weeks duration participated in the study. In the intensive group training protocol exercise therapy, back school and operant-conditioning behavioural principles are combined. Patients were treated during 10 individual sessions along 20 group sessions. Usual care consisted of physiotherapy according to the Dutch guidelines for Low Back Pain. Main outcome measures were functional disability (Roland Morris disability questionnaire), pain intensity, perceived recovery and sick leave because of low back pain assessed at baseline and after 6, 13, 26 and 52 weeks. Both an intention-to-treat analysis and a per-protocol analysis were performed. Multilevel analysis did not show significant differences between both treatment groups on any outcome measures during the complete follow-up period, with one exception. After 26 weeks the protocol group showed more reduction in pain intensity than the guideline group, but this difference was absent after 52 weeks. We finally conclude that an intensive group training protocol was not more effective than usual physiotherapy for chronic low back pain.

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.

Breakthrough pain (BTP) is traditionally defined as a transitory pain flare in opioid-treated patients with chronic background pain. This definition has, however, been challenged in recent years. This study aimed to analyze BTP prevalence in different pain conditions. This was a prospective, non-interventional, observational study conducted from June to September 2011 in two Italian pain treatment reference centres. Consecutive patients aged >18 years with oncological or non-oncological pain were eligible for this study; background pain was acute/ subacute (<3 months) or chronic (>3 months). The characteristics of pain were evaluated by means of a structured interview by physicians, and patients were asked to complete a dedicated clinical study form. The following outcomes were assessed: chronic pain duration (in patients with chronic pain), BTP prevalence, and number and severity of daily BTP episodes. All outcomes were assessed in four populations of patients with: (a) chronic oncological pain; (b) chronic non-oncological pain; (c) non-chronic oncological pain; (d) non-chronic non-oncological pain. The correlation between BTP and gender was also investigated. Of 1,270 patients with chronic pain, 1,086 had non-oncological pain (85.5%). Most patients (68.6%) with non-oncological pain were female (P = 0.001). Pain duration was significantly longer in non-oncological pain versus oncological pain groups (P = 0.002). BTP prevalence was lower in non-oncological patients (P < 0.001). No differences were reported in terms of number and severity of daily BTP episodes. BTP was more frequent in females with non-oncological pain (P = 0.04). Females had a significantly higher pain severity (P = 0.02) than males. BTP is frequently reported in patients who do not have BTP according to the traditional definition. BTP frequency and severity is similar in oncological and non-oncological pain.

The consequences of ubiquitous exposure to environmental chemicals remain poorly defined. Non-targeted metabolomic profiling is an emerging method to identify biomarkers of the physiological response to such exposures. We investigated the effect of three commonly used ingredients in personal care products, diethyl phthalate (DEP), methylparaben (MPB) and triclosan (TCS), on the blood metabolome of female Sprague-Dawley rats. Animals were treated with low levels of these chemicals comparable to human exposures during prepubertal and pubertal windows as well as chronically from birth to adulthood. Non-targeted metabolomic profiling revealed that most of the variation in the metabolites was associated with developmental stage. The low-dose exposure to DEP, MPB and TCS had a relatively small, but detectable impact on the metabolome. Multiple metabolites that were affected by chemical exposure belonged to the same biochemical pathways including phenol sulfonation and metabolism of pyruvate, lyso-plasmalogens, unsaturated fatty acids and serotonin. Changes in phenol sulfonation and pyruvate metabolism were most pronounced in rats exposed to DEP during the prepubertal period. Our metabolomics analysis demonstrates that human level exposure to personal care product ingredients has detectable effects on the rat metabolome. We highlight specific pathways such as sulfonation that warrant further study.

"A variety of life table models were used for the analysis of the (1984-86) Kuwaiti cause-specific mortality data. These models comprised total mortality, multiple-decrement, cause-elimination, cause-delay and disease dependency. The models were illustrated by application to a set of four chronic diseases: hypertensive, ischaemic heart, cerebrovascular and diabetes mellitus. The life table methods quantify the relative weights of different diseases as hazards to mortality after adjustment for other causes. They can also evaluate the extent of dependency between underlying cause of death and other causes mentioned on [the] death certificate using an extended underlying-cause model."

Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic rhinosinusitis with nasal polyps, asthma, and reactions to cyclooxygenase-1-inhibiting drugs. This condition is often refractory to standard medical treatments and results in aggressive nasal polyposis that often requires multiple sinus surgeries. Aspirin desensitization followed by daily aspirin therapy is an important treatment option, and its efficacy has been validated in multiple research studies. Aspirin desensitization is not without risk, but specific protocols and recommendations exist to mitigate the risk. Most patients with AERD can undergo aspirin desensitization in an outpatient setting under the supervision of an allergist. Copyright © 2016 Elsevier Inc. All rights reserved.

Despite the overall negative impact of chronic rejection on quality of life and survival after lung transplant, the specific clinical indicators of deterioration have not been identified. To describe the course of illness after the onset of chronic rejection, including demographic and transplant variables, morbidity, mortality, health resource utilization, and end-of-life care, and to identify clinical indicators of deterioration in health and limited survival after the onset of chronic rejection. The medical records of 311 recipients of lung transplants between 1998 and 2004 were reviewed retrospectively to identify 60 recipients who experienced chronic rejection. Median survival after chronic rejection was 31.34 months. Time to rejection (mean, 26.05 months; SD, 16.85) was significantly correlated with overall survival without need of a retransplant (r = 0.64; P < .001). The earlier the onset of chronic rejection or the need for oxygen at home, the shorter was the period of survival after chronic rejection and the more frequent were hospital and intensive care unit admissions and prolonged stays. Of the 26 recipients who died, 65% died at the transplant center, and all but 1 died in the intensive care unit; 3 died after multiple attempts of cardiopulmonary resuscitation; life support was ultimately withdrawn in 69%. Lung transplant recipients who experience chronic graft rejection have high rates of morbidity, mortality, and health resource utilization; however, the course of illness after chronic rejection is highly variable.

Honey is recommended for non-specific acute paediatric cough by the Australian guidelines. Current available randomised clinical trials evaluated the effects of a single evening dose of honey, but multiple doses outcomes have never been studied. To evaluate the effects of wildflower honey, given for three subsequent evenings, on non-specific acute paediatric cough, compared to dextromethorphan (DM) and levodropropizine (LDP), which are the most prescribed over-the-counter (OTC) antitussives in Italy. 134 children suffering from non-specific acute cough were randomised to receive for three subsequent evenings a mixture of milk (90ml) and wildflower honey (10ml) or a dose of DM or LDP adjusted for the specific age. The effectiveness was evaluated by a cough questionnaire answered by parents. Primary end-point efficacy was therapeutic success. The latter was defined as a decrease in cough questionnaire score greater than 50% after treatment compared with baseline values. Three children were excluded from the study, as their parents did not complete the questionnaire. Therapeutic success was achieved by 80% in the honey and milk group and 87% in OTC medication group (p=0.25). Milk and honey mixture seems to be at least as effective as DM or LDP in non-specific acute cough in children. These results are in line with previous studies, which reported the health effects of honey on paediatric cough, even if placebo effect cannot be totally excluded. Copyright © 2014 SEICAP.

Multiple myeloma is a plasma cell malignancy characterized by monoclonal gammopathy and osteolytic bone lesions. Multiple myeloma is most commonly diagnosed in late disease stages, presenting with pathologic fracture. Early diagnosis and monitoring of disease status may improve quality of life and long-term survival for multiple myeloma patients from what is now a devastating and fatal disease. We have developed a near-infrared targeted fluorescent molecular probe with high affinity to the α4β1 integrin receptor (VLA-4)overexpressed by a majority of multiple myeloma cells as a non-radioactive analog to PET/CT tracer currently being developed for human diagnostics. A near-infrared dye that emits about 700 nm was conjugated to a high affinity peptidomimmetic. Binding affinity and specificity for multiple myeloma cells was investigated in vitro by tissue staining and flow cytometry. After demonstration of sensitivity and specificity, preclinical optical imaging studies were performed to evaluate tumor specificity in murine subcutaneous and metastatic multiple myeloma models. The VLA-4-targeted molecular probe showed high affinity for subcutaneous MM tumor xenografts. Importantly, tumor cells specific accumulation in the bone marrow of metastatic multiple myeloma correlated with GFP signal from transfected cells. Ex vivo flow cytometry of tumor tissue and bone marrow further corroborated in vivo imaging data, demonstrating the specificity of the novel agent and potential for quantitative imaging of multiple myeloma burden in these models.

Elephantiasis nostras verrucosa represents an infrequent clinical entity with cutaneous changes characterized by dermal fibrosis, hyperkeratotic verrucous and papillamotous lesions resulting from chronic non-filarial lymphedema secondary to infections, surgeries, tumor obstruction, radiation, congestive heart failure, and obesity. Although recurrent streptococcal lymphangitis is believed to play a critical role in the origin of elephantiasis nostras verrucosa, the exact pathogenesis of the disorder is not yet clear. Therapeutic efforts should aim to reduce lymph stasis, which will also lead to improvement of the cutaneous changes but unfortunately there is no specific treatment for advanced cases. In this report, we present a patient who was treated by below knee amputation as a result of elephantiasis nostras verrucosa complicated with chronic tibial osteomyelitis.

Type D personality has been associated with impaired health status in chronic heart failure (CHF), but other psychological factors may also be important. To determine whether non-Type D patients with low positive affect and Type D patients report lower health status, compared with non-Type D patients with high positive affect at 12-month follow-up in chronic heart failure. Consecutive CHF outpatients (n = 276) filled out the Short Form-12 (health status) and Health Complaints Scale (disease-specific complaints) at inclusion and 12-month follow-up, and the DS14 (Type D personality) and positive affect (Global Mood Scale) at inclusion. Three groups were composed: non-Type D patients without anhedonia, non-Type D patients with anhedonia, and Type D patients. After controlling for demographic and clinical confounders, and scores at inclusion, anhedonic non-Type D patients reported lower mental health status (beta = -.19, P < .004), and more feelings of disability (beta = .10, P = .04), marginally lower physical health status (beta = -.11, P = .07), and equal levels of cardiac symptoms (beta = .04, P = .43), when compared with non-Type D's without anhedonia. Type D patients reported lower levels of impaired mental health status, more cardiac symptoms and feelings of disability (-.31 < beta < .17, all Ps < .05). A trend was shown for physical health status (beta = -.11, P = .09). Non-Type D patients low on positive affect and Type D patients report lower levels of health status in CHF, compared with non-Type D patients with high positive affect. Future studies need to determine whether lack of positive affect is associated with impaired clinical outcome.

Exposure to artificial radio frequency electromagnetic fields (EMFs) has increased significantly in recent decades. Therefore, there is a growing scientific and social interest in its influence on health, even upon exposure significantly below the applicable standards. The intensity of electromagnetic radiation in human environment is increasing and currently reaches astronomical levels that had never before experienced on our planet. The most influential process of EMF impact on living organisms, is its direct tissue penetration. The current established standards of exposure to EMFs in Poland and in the rest of the world are based on the thermal effect. It is well known that weak EMF could cause all sorts of dramatic non-thermal effects in body cells, tissues and organs. The observed symptoms are hardly to assign to other environmental factors occurring simultaneously in the human environment. Although, there are still ongoing discussions on non-thermal effects of EMF influence, on May 31, 2011--International Agency for Research on Cancer (IARC)--Agenda of World Health Organization (WHO) has classified radio electromagnetic fields, to a category 2B as potentially carcinogenic. Electromagnetic fields can be dangerous not only because of the risk of cancer, but also other health problems, including electromagnetic hypersensitivity (EHS). Electromagnetic hypersensitivity (EHS) is a phenomenon characterized by the appearance of symptoms after exposure of people to electromagnetic fields, generated by EHS is characterized as a syndrome with a broad spectrum of non-specific multiple organ symptoms including both acute and chronic inflammatory processes located mainly in the skin and nervous systems, as well as in respiratory, cardiovascular systems, and musculoskeletal system. WHO does not consider the EHS as a disease-- defined on the basis of medical diagnosis and symptoms associated with any known syndrome. The symptoms may be associated with a single source of EMF or be derived from a combination of many sources. Reported symptoms associated with electromagnetic fields are characterized by the overlapping effect with other individuals with these symptoms exhibited a broad spectrum of clinical manifestations, related to exposure to a single or multiple sources of EMF. The phenomenon of electromagnetic hypersensitivity in the form of dermatological disease is associated with mastocytosis. The biopsies taken from skin lesions of patients with EHS indicated on infiltration of the skin layers of the epidermis with mastocytes and their degranulation, as well as on release anaphylactic reaction mediators such as histamine, chymase and tryptase. The number of people suffering from EHS in the world is growing describing themselves as severely dysfunctional, showing multi organ non-specific symptoms upon exposure to low doses of electromagnetic radiation, often associated with hypersensitivity to many chemical agents (Multiple Chemical Sensitivity-MCS) and/or other environmental intolerances (Sensitivity Related Illness-SRI).

A total of 350 million individuals are affected by chronic hepatitis B virus infection world-wide. Historically, liver biopsy has been instrumental in adequately assessing patients with chronic liver disease. A number of non-invasive models have been studied world-wide. The aim of this study is to assess the utility of non-invasive mathematical models of liver fibrosis in chronic hepatitis B (CHB). Indian patients in a resource limited setting using routinely performed non-invasive laboratory investigations. A cross-sectional study carried out at a tertiary care center. A total of 52 consecutive chronic liver disease patients who underwent percutaneous liver biopsy and 25 healthy controls were enrolled in the study. Routine laboratory investigations included serum aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Gama glutamyl transpeptidase (GGT), total bilirubin, total cholesterol, prothrombin time and platelet count. Three non-invasive models for namely aspartate aminotransferase to platelet ratio index (APRI), Fibrosis 4 (FIB-4) and Forn's index were calculated. Outcomes were compared for the assessment of best predictor of fibrosis by calculating the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of each index. Medcalc online software and by Microsoft Excel Worksheet. Chi-square test was used for significance. P value < 0.05 was taken as significant. While the serum levels of AST, ALT and GGT were significantly higher in patients group as compare with the healthy controls (P < 0.01), the platelet counts were significantly lower in patient group as compared to the control group (P < 0.01). Mean value of all 3 indices were significantly higher in patients group as compare with the controls (P < 0.01). Out of the three indices, APRI index with a NPV of 95% appeared to be a better model for excluding significant liver fibrosis while FIB-4 with a PPV of 61% showed fair correlation with significant fibrosis. Thus, these two non-invasive models for predicting of liver fibrosis, namely APRI and FIB-4, can be utilized in combination as screening tools in monitoring of CHB patients, especially in resource limiting settings.

A New Mouse Model That Spontaneously Develops Chronic Liver Inflammation and Fibrosis

Here we characterize a new animal model that spontaneously develops chronic inflammation and fibrosis in multiple organs, the non-obese diabetic inflammation and fibrosis (N-IF) mouse. In the liver, the N-IF mouse displays inflammation and fibrosis particularly evident around portal tracts and central veins and accompanied with evidence of abnormal intrahepatic bile ducts. The extensive cellular infiltration consists mainly of macrophages, granulocytes, particularly eosinophils, and mast cells. This inflammatory syndrome is mediated by a transgenic population of natural killer T cells (NKT) induced in an immunodeficient NOD genetic background. The disease is transferrable to immunodeficient recipients, while polyclonal T cells from unaffected syngeneic donors can inhibit the disease phenotype. Because of the fibrotic component, early on-set, spontaneous nature and reproducibility, this novel mouse model provides a unique tool to gain further insight into the underlying mechanisms mediating transformation of chronic inflammation into fibrosis and to evaluate intervention protocols for treating conditions of fibrotic disorders.

Multiple sclerosis is a disease that is characterized by inflammation, demyelination, and axonal damage; it ultimately forms gliotic scars and lesions that severely compromise the function of the central nervous system. Evidence has shown previously that altered growth factor receptor signaling contributes to lesion formation, impedes recovery, and plays a role in disease progression. Growth arrest-specific protein 6 (Gas6), the ligand for the TAM receptor tyrosine kinase family, consisting of Tyro3, Axl, and Mer, is important for cell growth, survival, and clearance of debris. In this study, we show that levels of membrane-bound Mer (205 kd), soluble Mer (∼150 kd), and soluble Axl (80 kd) were all significantly elevated in homogenates from established multiple sclerosis lesions comprised of both chronic active and chronic silent lesions. Whereas in normal tissue Gas6 positively correlated with soluble Axl and Mer, there was a negative correlation between Gas6 and soluble Axl and Mer in established multiple sclerosis lesions. In addition, increased levels of soluble Axl and Mer were associated with increased levels of mature ADAM17, mature ADAM10, and Furin, proteins that are associated with Axl and Mer solubilization. Soluble Axl and Mer are both known to act as decoy receptors and block Gas6 binding to membrane-bound receptors. These data suggest that in multiple sclerosis lesions, dysregulation of protective Gas6 receptor signaling may prolong lesion activity. PMID:19541935

Non-specific low back pain (LBP) affects many people and has major socio-economic consequences. Traditional therapeutic strategies, mainly focused on biomechanical factors, have had moderate and short-term impact. Certain psychosocial factors have been linked to poor prognosis of LBP and they are increasingly considered as promising targets for management of LBP. Primary health care providers (HCPs) are involved in most of the management of people with LBP and they are skilled in providing comprehensive care, including consideration of psychosocial dimensions. This review aims to discuss three pieces of recent research focusing on psychosocial issues in LBP patients in primary care. In the first systematic review, the patients’ or HCPs’ overall judgment about the likely evolution of LBP was the factor most strongly linked to poor outcome, with predictive validity similar to that of multidimensional scales. This result may be explained by the implicit aggregation of many prognostic factors underlying this judgment and suggests the relevance of considering the patients from biopsychosocial and longitudinal points of view. The second review showed that most of the interventions targeting psychosocial factors in LBP in primary care have to date focused on the cognitive-behavioral factors, resulting in little impact. It is unlikely that any intervention focusing on a single factor would ever fit the needs of most patients; interventions targeting determinants from several fields (mainly psychosocial, biomechanical, and occupational) may be more relevant. Should multiple stakeholders be involved in such interventions, enhanced interprofessional collaboration would be critical to ensure the delivery of coordinated care. Finally, in the third study, the prevalence of psychosocial comorbidity in chronic LBP patients was not found to be significantly higher than in other patients consulting in primary care. Rather than specifically screening for psychosocial conditions, this suggests taking into account any potential comorbidity in patients with chronic LBP, as in other patients. All these results support the adoption of a more comprehensive and patient-centered approach when dealing with patients with LBP in primary care. As this condition is illustrative of many situations encountered in primary care, the strategies proposed here may benefit most patients consulting in this setting. PMID:26501062

There is lack of evidence for specific treatment interventions for patients with non-specific chronic low back pain (NSCLBP) despite the substantial amount of randomised controlled clinical trials evaluating treatment outcome for this disorder. It has been hypothesised that this vacuum of evidence is caused by the lack of subclassification of the heterogeneous population of patients with chronic low back pain for outcome research. A systematic review. A systematic review with a meta-analysis was undertaken to determine the integration of subclassification strategies with matched interventions in randomised controlled clinical trials evaluating manual therapy treatment and exercise therapy for NSCLBP. A structured search for relevant studies in Embase, Cinahl, Medline, PEDro and the Cochrane Trials Register database, followed by hand searching all relevant studies in English up to December 2008. Only 5 of 68 studies (7.4%) subclassified patients beyond applying general inclusion and exclusion criteria. In the few studies where classification and matched interventions have been used, our meta-analysis showed a statistical difference in favour of the classification-based intervention for reductions in pain (p=0.004) and disability (p=0.0005), both for short-term and long-term reduction in pain (p=0.001). Effect sizes ranged from moderate (0.43) for short term to minimal (0.14) for long term. A better integration of subclassification strategies in NSCLBP outcome research is needed. We propose the development of explicit recommendations for the use of subclassification strategies and evaluation of targeted interventions in future research evaluating NSCLBP.

The objective of this research was to update earlier estimates of prevalence rates of single chronic conditions and multiple (>2) chronic conditions (MCC) among the noninstitutionalized, civilian US adult population. Data from the 2012 National Health Interview Survey (NHIS) were used to generate estimates of MCC for US adults and by select demographic characteristics. Approximately half (117 million) of US adults have at least one of the 10 chronic conditions examined (ie, hypertension, coronary heart disease, stroke, diabetes, cancer, arthritis, hepatitis, weak or failing kidneys, current asthma, or chronic obstructive pulmonary disease [COPD]). Furthermore, 1 in 4 adults has MCC. PMID:24742395

Haemophilia is characterized by frequent haemarthrosis, leading to acute/chronic joint pain. To assess self-reported prevalence, description and management of pain in adult males with mild-to-severe haemophilia and history of joint pain/bleeding. Participants completed a pain survey and five patient-reported outcome instruments assessing pain, functional impairment and health-related quality of life (HRQoL). Of 381 participants enrolled, median age was 34 years; 77% had haemophilia A, 71% had severe disease and 65% were overweight/obese. Many (56%) were not receiving routine infusions; 30% never received routine infusions. During the prior 6 months, 20% experienced acute pain, 34% chronic pain and 32% both acute/chronic pain. Subjects with both acute/chronic pain (vs. none, acute or chronic) were more likely to be depressed (30% vs. 0-15%), obese (35% vs. 20-29%) and have lower HRQoL (mean EQ-5D visual analog scale, 69 vs. 83-86) and function (median overall Hemophilia Activities List, 60 vs. 88-99). Most common analgesics used for acute/chronic pain during the prior 6 months were acetaminophen (62%/55%) and non-steroidal anti-inflammatory drugs (34%/49%); most common non-pharmacologic strategies were ice (65%/33%) and rest (51%/33%). Hydrocodone-acetaminophen was the most common opioid for both acute/chronic pain (30%); other long-acting opioids were infrequently used specifically for chronic but not acute pain (morphine, 7%; methadone, 6%; fentanyl patch, 2%). Patients with chronic pain, particularly those with both acute/chronic pain, frequently experience psychological issues, functional disability and reduced HRQoL. Treatment strategies for acute pain (e.g. routine infusions to prevent bleeding) and for chronic pain (e.g. long-acting opioids) may be underused. © 2017 The Authors.

The transition from acute to chronic ethanol exposure leads to lasting behavioral and physiological changes such as increased consumption, dependence, and withdrawal. Changes in brain gene expression are hypothesized to underlie these adaptive responses to ethanol. Previous studies on acute ethanol identified genetic variation in brain gene expression networks and behavioral responses to ethanol across the BXD panel of recombinant inbred mice. In this work, we have performed the first joint genetic and genomic analysis of transcriptome shifts in response to chronic intermittent ethanol (CIE) by vapor chamber exposure in a BXD cohort. CIE treatment is known to produce significant and sustained changes in ethanol consumption with repeated cycles of ethanol vapor. Using Affymetrix microarray analysis of prefrontal cortex (PFC) and nucleus accumbens (NAC) RNA, we compared CIE expression responses to those seen following acute ethanol treatment, and to voluntary ethanol consumption. Gene expression changes in PFC and NAC after CIE overlapped significantly across brain regions and with previously published expression following acute ethanol. Genes highly modulated by CIE were enriched for specific biological processes including synaptic transmission, neuron ensheathment, intracellular signaling, and neuronal projection development. Expression quantitative trait locus (eQTL) analyses identified genomic loci associated with ethanol-induced transcriptional changes with largely distinct loci identified between brain regions. Correlating CIE-regulated genes to ethanol consumption data identified specific genes highly associated with variation in the increase in drinking seen with repeated cycles of CIE. In particular, multiple myelin-related genes were identified. Furthermore, genetic variance in or near dynamin3 (Dnm3) on Chr1 at ~164 Mb may have a major regulatory role in CIE-responsive gene expression. Dnm3 expression correlates significantly with ethanol consumption, is contained in a highly ranked functional group of CIE-regulated genes in the NAC, and has a cis-eQTL within a genomic region linked with multiple CIE-responsive genes.

Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. While in the past, pain was largely dismissed and was frequently left untreated, views on children's pain have changed over time, and relief of pain is now seen as important.We designed a suite of seven reviews on chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol as priority areas) in order to review the evidence for children's pain utilising pharmacological interventions in children and adolescents.As the leading cause of morbidity in children and adolescents in the world today, chronic disease (and its associated pain) is a major health concern. Chronic pain (lasting three months or longer) can arise in the paediatric population in a variety of pathophysiological classifications: nociceptive, neuropathic, idiopathic, visceral, nerve damage pain, chronic musculoskeletal pain, and chronic abdominal pain, and other unknown reasons.Paracetamol (acetaminophen) is one of the most widely used analgesics in both adults and children. The recommended dosage in the UK, Europe, Australia, and the USA for children and adolescents is generally 10 to 15 mg/kg every four to six hours, with specific age ranges from 60 mg (6 to 12 months old) up to 500 to 1000 mg (over 12 years old). Paracetamol is the only recommended analgesic for children under 3 months of age. Paracetamol has been proven to be safe in appropriate and controlled dosages, however potential adverse effects of paracetamol if overdosed or overused in children include liver and kidney failure. To assess the analgesic efficacy and adverse events of paracetamol (acetaminophen) used to treat chronic non-cancer pain in children and adolescents aged between birth and 17 years, in any setting. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online, MEDLINE via Ovid, and Embase via Ovid from inception to 6 September 2016. We also searched the reference lists of retrieved studies and reviews, and searched online clinical trial registries. Randomised controlled trials, with or without blinding, of any dose and any route, treating chronic non-cancer pain in children and adolescents, comparing paracetamol with placebo or an active comparator. Two review authors independently assessed studies for eligibility. We planned to use dichotomous data to calculate risk ratio and numbers needed to treat, using standard methods where data were available. We assessed GRADE (Grading of Recommendations Assessment, Development and Evaluation) and planned to create a 'Summary of findings' table. No studies were eligible for inclusion in this review. We rated the quality of the evidence as very low. We downgraded the quality of evidence by three levels due to the lack of data reported for any outcome. There was no evidence from randomised controlled trials to support or refute the use of paracetamol (acetaminophen) to treat chronic non-cancer pain in children and adolescents. We are unable to comment about efficacy or harm from the use of paracetamol to treat chronic non-cancer pain in children and adolescents.We know from adult randomised controlled trials that paracetamol, can be effective, in certain doses, and in certain pain conditions (not always chronic).This means that no conclusions could be made about efficacy or harm in the use of paracetamol (acetaminophen) to treat chronic non-cancer pain in children and adolescents.

Molecular Pharmacology of δ-Opioid Receptors

Opioids are among the most effective analgesics available and are the first choice in the treatment of acute severe pain. However, partial efficacy, a tendency to produce tolerance, and a host of ill-tolerated side effects make clinically available opioids less effective in the management of chronic pain syndromes. Given that most therapeutic opioids produce their actions via µ-opioid receptors (MOPrs), other targets are constantly being explored, among which δ-opioid receptors (DOPrs) are being increasingly considered as promising alternatives. This review addresses DOPrs from the perspective of cellular and molecular determinants of their pharmacological diversity. Thus, DOPr ligands are examined in terms of structural and functional variety, DOPrs’ capacity to engage a multiplicity of canonical and noncanonical G protein–dependent responses is surveyed, and evidence supporting ligand-specific signaling and regulation is analyzed. Pharmacological DOPr subtypes are examined in light of the ability of DOPr to organize into multimeric arrays and to adopt multiple active conformations as well as differences in ligand kinetics. Current knowledge on DOPr targeting to the membrane is examined as a means of understanding how these receptors are especially active in chronic pain management. Insight into cellular and molecular mechanisms of pharmacological diversity should guide the rational design of more effective, longer-lasting, and better-tolerated opioid analgesics for chronic pain management.

Physiological and functional failure in chronic obstructive pulmonary disease, congestive heart failure and cancer: a debilitating intersection of sarcopenia, cachexia and breathlessness.

Loss of skeletal muscle mass and cachexia are important manifestations of chronic obstructive pulmonary disease and have been associated with breathlessness, functional limitation and poor prognosis. A number of other life-limiting illnesses, including cancer and chronic heart failure as well as acute conditions seen in ICU such as sepsis, are characteristically associated with cachexia and sarcopenia. These conditions may have respiratory muscle atrophy of sufficient magnitude to contribute to the development of breathlessness and associated functional limitation. The purpose of this review is to summarize findings related to a direct role for severe respiratory muscle wasting in the etiology of breathlessness in advanced, life limiting illness. Localized wasting of respiratory muscles appears to be part of systemic wasting of skeletal muscles, driven by deconditioning, nutritional insufficiencies and inflammation, and because of disease-specific factors (tumor factors and exacerbations), anabolic insufficiency, autonomic dysfunction, drugs (such as corticosteroids and chemotherapy agents), mechanical ventilation and comorbidities. Marked morphological and biochemical abnormalities have been noted in diaphragm muscle biopsies. Older patients with multiple comorbidities associated with muscle loss and cachexia are likely to be at elevated risk of respiratory muscle atrophy and functional loss, because of the presence of multiple, interacting etiologic factors.

[MicroRNAs: circulating biomarkers in type 2 Diabetes Mellitus and physical exercise].

MicroRNAs are small, non-coding molecules with a crucial function in the cell´s biologic regulation. Circulating levels of miRNAs may be useful biomarkers in metabolic diseases such as type 2 Diabetes Mellitus (DM2), which alters the circulating concentrations of several types of miRNA. Specific serum profiles of these molecules have been identified in high-risk patients before the development of DM2 and its chronic complications. Most importantly, these profiles can be modified with physical exercise, which is crucial in the treatment of metabolic diseases. Acute physical activity alone can induce changes in tissue specific miRNAs, and responses are different in aerobic or non-aerobic training. Muscle and cardiovascular miRNAs, which may play an important role in the adap tation to exercise, are predominantly altered. Even further, there is a correlation between serum levels of miRNAs and fitness, suggesting a role for chronic exercise in their regulation. Thus, miRNAs are molecules of growing importance in exercise physiology, and may be involved in the mechanisms behind the beneficial effects of physical activity for patients with metabolic diseases.

A Knowledge-Modeling Approach to Integrate Multiple Clinical Practice Guidelines to Provide Evidence-Based Clinical Decision Support for Managing Comorbid Conditions.

Clinical management of comorbidities is a challenge, especially in a clinical decision support setting, as it requires the safe and efficient reconciliation of multiple disease-specific clinical procedures to formulate a comorbid therapeutic plan that is both effective and safe for the patient. In this paper we pursue the integration of multiple disease-specific Clinical Practice Guidelines (CPG) in order to manage co-morbidities within a computerized Clinical Decision Support System (CDSS). We present a CPG integration framework-termed as COMET (Comorbidity Ontological Modeling & ExecuTion) that manifests a knowledge management approach to model, computerize and integrate multiple CPG to yield a comorbid CPG knowledge model that upon execution can provide evidence-based recommendations for handling comorbid patients. COMET exploits semantic web technologies to achieve (a) CPG knowledge synthesis to translate a paper-based CPG to disease-specific clinical pathways (CP) that include specialized co-morbidity management procedures based on input from domain experts; (b) CPG knowledge modeling to computerize the disease-specific CP using a Comorbidity CPG ontology; (c) CPG knowledge integration by aligning multiple ontologically-modeled CP to develop a unified comorbid CPG knowledge model; and (e) CPG knowledge execution using reasoning engines to derive CPG-mediated recommendations for managing patients with comorbidities. We present a web-accessible COMET CDSS that provides family physicians with CPG-mediated comorbidity decision support to manage Atrial Fibrillation and Chronic Heart Failure. We present our qualitative and quantitative analysis of the knowledge content and usability of COMET CDSS.

Tinnitus is often associated with disturbed sleep, but there are also patients without sleep problems. The mechanisms for developing insomnia or not in tinnitus patients are still unknown. The aim of the present study was to extract possible tinnitus specific factors that increase the risk of developing insomnia based on the analysis of a large patient cohort suffering from chronic tinnitus. 173 patients presenting at the multidisciplinary tinnitus center of a University Hospital completed a questionnaire measuring specific psychological symptoms of insomnia (RIS) and a tinnitus questionnaire (TQ). The scores of all ten RIS items were compared between tinnitus patients and 94 healthy individuals by separate ANOVAs in order to specify the extent of insomnia specific symptoms in the tinnitus group. In a second step a multiple linear regression analysis was performed in the tinnitus sample with subscales of the TQ (excluding the TQ sleep scale), age and duration of tinnitus as independent variables and the RIS score as the dependent variables. Tinnitus patients differed from healthy controls not only in impaired sleep quality but also in insomnia specific concerns and anxiety. Tinnitus related emotional and cognitive distress and somatic complaints correlated with severity of insomnia, whereas no association of age or duration of tinnitus with severity of insomnia was found. Our results suggest that chronic tinnitus patients have more sleeping difficulties and associated worries about sleep or negative emotions in contrast to healthy controls. Tinnitus-related distress is related to insomnia. Copyright © 2016. Published by Elsevier Inc.
