    To evaluate the sub-healthy status of community residents and its main relevant factors. The proportional stratified random sampling was selected to take the sample of 5000 community residents from two communities in Fujian province. The sub-healthy status and its main influence factors were measured with the method of physical examination and questionnaire. The women, the oldest group (≥60 years old) and the divorce/widowed group were found to have the higher scores of sub-health status than others (P <0. 05). Multivariate analysis showed that female, age, education level and irregular eating were the main risk factors for the three dimensions of sub-health status. Divorced or widowed statue was unfavorable factors for physical and psychological sub-health status. Quit smoking was found to be significant risk factor for psychological and social sub-health status. Body mass index (BMI) was related to physical sub-health status, alone. While physical exercise was the main protective factor for sub-health status. Improving behavioral habits, maintaining stable family, maintaining normal BMI may be important to prevent sub-health status among community residents.

    Objectives In epidemiological studies, it is important to identify independent associations between collective exposures and a health outcome. The current stepwise selection technique ignores stochastic errors and suffers from a lack of stability. The alternative LASSO-penalized regression model can be applied to detect significant predictors from a pool of candidate variables. However, this technique is prone to false positives and tends to create excessive biases. It remains challenging to develop robust variable selection methods and enhance predictability. Material and methods Two improved algorithms denoted the two-stage hybrid and bootstrap ranking procedures, both using a LASSO-type penalty, were developed for epidemiological association analysis. The performance of the proposed procedures and other methods including conventional LASSO, Bolasso, stepwise and stability selection models were evaluated using intensive simulation. In addition, methods were compared by using an empirical analysis based on large-scale survey data of hepatitis B infection-relevant factors among Guangdong residents. Results The proposed procedures produced comparable or less biased selection results when compared to conventional variable selection models. In total, the two newly proposed procedures were stable with respect to various scenarios of simulation, demonstrating a higher power and a lower false positive rate during variable selection than the compared methods. In empirical analysis, the proposed procedures yielding a sparse set of hepatitis B infection-relevant factors gave the best predictive performance and showed that the procedures were able to select a more stringent set of factors. The individual history of hepatitis B vaccination, family and individual history of hepatitis B infection were associated with hepatitis B infection in the studied residents according to the proposed procedures. Conclusions The newly proposed procedures improve the identification of

    2017-01-01

    Chemokines play an important role in normal bone physiology and the pathophysiology of many bone diseases. The recent increased focus on the individual roles of this class of proteins in the context of bone has shown that members of the two major chemokine subfamilies—CC and CXC—support or promote the formation of new bone and the remodeling of existing bone in response to a myriad of stimuli. These chemotactic molecules are crucial in orchestrating appropriate cellular homing, osteoblastogenesis, and osteoclastogenesis during normal bone repair. Bone healing is a complex cascade of carefully regulated processes, including inflammation, progenitor cell recruitment, differentiation, and remodeling. The extensive role of chemokines in these processes and the known links between environmental contaminants and chemokine expression/activity leaves ample opportunity for disruption of bone healing by environmental factors. However, despite increased clinical awareness, the potential impact of many of these environmental factors on bone-related chemokines is still ill defined. A great deal of focus has been placed on environmental exposure to various endocrine disruptors (bisphenol A, phthalate esters, etc.), volatile organic compounds, dioxins, and heavy metals, though mainly in other tissues. Awareness of the impact of other less well-studied bone toxicants, such as fluoride, mold and fungal toxins, asbestos, and chlorine, is also reviewed. In many cases, the literature on these toxins in osteogenic models is lacking. However, research focused on their effects in other tissues and cell lines provides clues for where future resources could be best utilized. This review aims to serve as a current and exhaustive resource detailing the known links between several classes of high-interest environmental pollutants and their interaction with the chemokines relevant to bone healing.

  8. Bipolar spectrum: Relevant psychological and biological factors.

    PubMed

    Terao, Takeshi

    2012-10-22

    The bipolar spectrum is a concept which bridges bipolar I disorder and unipolar depression. As Kraepelin described, there may be continuity across mood disorders. If this is the case, why should we discriminate for drug choice For example, it is generally accepted that mood stabilizers should be used for the bipolar spectrum, whereas antidepressants are for unipolar depression. If these disorders are diagnostically continuous, it is possible that the same drug could be effective in treating both bipolar I disorder/spectrum and unipolar depression. To resolve this question, I would like to propose my hypothesis that there is an inflexion point which constitutes the boundary between the bipolar spectrum and unipolar depression. It is likely that this inflexion point consists of temperaments as, reportedly, there are many significant differences in the presence of various temperaments between the bipolar spectrum (bipolar II, II1/2 and IV) and unipolar depression. These findings suggest that temperaments could draw a boundary between the bipolar spectrum and unipolar depression. Moreover, it has been shown that certain temperaments may be associated with several biological factors and may be associated with drug response. As such, whilst the concept of the bipolar spectrum emphasizes continuity, it is the proposed inflexion point that discriminates drug responses between the bipolar spectrum and unipolar depression. At the moment, although hypothetical, I consider this idea worthy of further research.

    The study goal is to highlight strategies for promoting relevance of research capacity-building efforts targeting community organizations (CO)s. Two community partners, representing two COs, were invited to participate in CO research development trainings, Community Research Forums (Forum)s. Their contributions were documented via Forum document review. Forum participants, representatives from other COs, completed post-Forum surveys to identify additional training needs and rate Forum impact relative to their training expectations. A content-based analysis and descriptive statistics were used to summarize needs assessment- and impact-related survey responses, respectively. Community partners were involved in eight Forum-related activities including marketing (planning), facilitation (implementation), and manuscript coauthorship (dissemination). Eighty-one individuals, representing 55 COs, attended the Forums. Needs assessment responses revealed a desire for additional assistance with existing Forum topics (e.g., defining research priorities) and a need for new ones (e.g., promoting organizational buy in for research). Ninety-one percent of participants agreed that the Forum demonstrated the value of research to COs and how to create a research agenda. Including community partners in all Forum phases ensured that CO perspectives were integrated throughout. Post-Forum needs and impact assessment results will help in tailoring, where needed, future training topics and strategies, respectively. © 2015 Wiley Periodicals, Inc.

  13. Dissociative absorption: An empirically unique, clinically relevant, dissociative factor.

    2015-11-01

    Research of dissociative absorption has raised two questions: (a) Is absorption a unique dissociative factor within a three-factor structure, or a part of one general dissociative factor? Even when three factors are found, the specificity of the absorption factor is questionable. (b) Is absorption implicated in psychopathology? Although commonly viewed as "non-clinical" dissociation, absorption was recently hypothesized to be specifically associated with obsessive-compulsive symptoms. To address these questions, we conducted exploratory and confirmatory factor analyses on 679 undergraduates. Analyses supported the three-factor model, and a "purified" absorption scale was extracted from the original inclusive absorption factor. The purified scale predicted several psychopathology scales. As hypothesized, absorption was a stronger predictor of obsessive-compulsive symptoms than of general psychopathology. In addition, absorption was the only dissociative scale that longitudinally predicted obsessive-compulsive symptoms. We conclude that absorption is a unique and clinically relevant dissociative tendency that is particularly meaningful to obsessive-compulsive symptoms. Copyright © 2015 Elsevier Inc.

    2016-02-01

    The Main purpose of vocational rehabilitation is occupational reintegration of clients into the job market who have lost their job or whose job is threatened because of a handicap or chronicl illness. With regard to existing evidence for the relevance of personality factors for work performance and job achievement, the present study investigated the influence of participants' personality factors on a successful reintegration after a retraining program in a vocational training center over 2 years. A central research objective was to identify prognostic personality factors for successful vocational integration. In this longitudinal study 15 vocational training centers participated at 3 time points of measurement (T1, T2 and T3). Data gathering was based on rehabilitants' self-reports (standardized questionnaires: SVF, BSW, SPR, CSES) about personality aspects. First data collection started at the beginning (T1) and a second survey was conducted at the end of the training 2 years later (T2). Based on the data at measurement points T1 and T2, 4 prognostic models were computed (binary logistic regression analysis) and evaluated, examining the differenzial influence of several scales and items on direct reintegration after completing the vocational retraining and reintegration status 6 months later (T3). As expected, different variables turned out to be relevant for occupational integration at the end of the training program and 6 months later. Correspondingly other variables appeared to be relevant for occupational reintegration at T1 and at T2. At the end of the vocational training program, approximately 24% of the participants had a job. With respect to direct reintegration, regression analysis revealed that vocational self-efficacy (R(2)=0,175) and self-evaluation were relevant (R(2)=0,383). Approximately 70% of the participants had gotten a job 6 months later. Several stress coping strategies (R(2)=0,170), estimation of the own reintegration prognosis and aspects

    This article describes the use of interactive theater, audience response assessment, and peer educators to create community-generated approaches for bystander interventions (i.e., actions taken by people who become aware of controlling, abusive and violent behavior of others) to prevent intimate partner violence (IPV) and to foster change in community norms. We include a case example of an ongoing university-community partnership, which mobilizes community members to develop and implement socioculturally relevant IPV prevention programs in multiple Asian communities. We used interactive theater at a community event--a walk to raise awareness about IPV in South Asian communities--and examined how the enacted bystander interventions reflect specific community contexts. We detail the challenges and limitations we have encountered in our attempts to implement this approach in collaboration with our community partners.

  18. Relevant Cytokines in the Management of Community-Acquired Pneumonia.

    2016-03-01

    Community-acquired pneumonia (CAP) is the leading cause of infectious death in the world. Immune dysregulation during acute lung infection plays a role in lung injury and the systemic inflammatory response. Cytokines seem to be major players in severe lung infection cases. Here, we present a review of published papers in the last 3 years regarding this topic. The cytokine response during pneumonia is different in bacterial vs viral infections; some of these cytokines correlate with clinical severity scales such as CURB65 or SOFA. Treatment focused in the cytokine environment is an interesting area that could impact the prognosis of CAP. Some of the agents that have been studied as co-adjuvant therapy are corticosteroids, macrolides, and linezolid, but anyone of those have shown a clear or proven efficacy or have been recommended as a part of the standard of care for CAP. More studies designed to define the role of immunomodulatory agents, such as co-adjuvant therapy in pneumonia, are needed.

    Thin, vertically structured topsoil communities that become ecologically important in arid regions (biological soil crusts or BSCs) are responsible for much of the nitrogen inputs into pristine arid lands. We studied N2 fixation and ammonium oxidation (AO) at subcentimetre resolution within BSCs from the Colorado Plateau. Pools of dissolved porewater nitrate/ nitrite, ammonium and organic nitrogen in wetted BSCs were high in comparison with those typical of aridosoils. They remained stable during incubations, indicating that input and output processes were of similar magnitude. Areal N2 fixation rates (6.5-48 ??mol C2H2 m-2 h -1) were high, the vertical distribution of N2 fixation peaking close to the surface if populations of heterocystous cyanobacteria were present, but in the subsurface if they were absent. Areal AO rates (19-46 ??mol N m-2 h-1) were commensurate with N2 fixation inputs. When considering oxygen availability, AO activity invariably peaked 2-3 mm deep and was limited by oxygen (not ammonium) supply. Most probable number (MPN)-enumerated ammonia-oxidizing bacteria (6.7-7.9 ?? 103 cells g-1 on average) clearly peaked at 2-3 mm depth. Thus, AO (hence nitrification) is a spatially restricted but important process in the nitrogen cycling of BSC, turning much of the biologically fixed nitrogen into oxidized forms, the fate of which remains to be determined.

    The objective of the study was to evaluate risk factors for pulmonary tuberculosis in systemic lupus erythematosus (SLE). Clinical/laboratorial features of 1283 SLE patients (ACR criteria) followed at the Lupus Clinic were obtained from the electronic register database from 2001 to 2009. Pulmonary tuberculosis was diagnosed in 20 patients (1.6%) (TB+ group). As control group (TB-), 40 patients without tuberculosis matched for age, gender, ethnicity, age at SLE diagnosis, and disease duration were arbitrarily selected. All 20 patients of the TB+ group presented confirmed pulmonary tuberculosis from 1 to 23 years after SLE diagnosis (7.6 ± 8.1 years). Frequencies of previous SLE involvements (cutaneous, articular, hematological, renal, pericarditis, pneumonitis, and central nervous system) were alike in TB+ and TB- groups (p > 0.05). In contrast, prior pleuritis was more frequent in the TB+ group (40% vs. 5%, p = 0.001). In fact, pulmonary tuberculosis was diagnosed in 8/10 patients with previous pleuritis. Immunosuppressive and corticosteroid therapies at the moment of tuberculosis diagnosis were also similar in both groups (p > 0.05). We have identified pleuritis as a relevant risk factor for pulmonary tuberculosis, suggesting that previous pleural injury is a critical part of the complex interplay between altered immune system, socio-economic conditions, and increased susceptibility to this mycobacterial infection.

  3. Pathophysiological relevance of forkhead transcription factors in brain ischemia.

    PubMed

    Fukunaga, Kohji; Shioda, Norifumi

    2009-01-01

    Forkhead box transcription factor, class 0 (FOXO) is a mammalian homologue of DAF-16, which is known to regulate the lifespan of Caenorhabditis elegans and includes subfamiies of forkhead transcription factors such as FOXO1 (FKHR). FOXO3 (FKHRL1), FOXO4 (AFX) and FOXO6. All these FOXO members are expressed in the brain with different spatial patterns. FOXO1 is phosphorylated on three sites (Thr-24, Ser-256 and Ser-319) in phosphatidylinositol 3-kinase (PI3-K)/Akt-dependenr manner, thereby inhibiting apoptosis signals. We here documented dephosphorylation of FOXO1, FOXO3 and FOXO4 following transient forebrain ischemia with its concomitant translocation into the nucleus in neurons in the gerbil and mouse brains. The dephosphorylarion of FOXO1 following brain ischemia is in part mediated by constirutively active calcineurin in the mouse hippocampus. The activation of FOXOs preceded delayed neuronal death in the vulnerable hippocampal regions following ischemic brain injury. The FOXOl activation is accompanied by an increase in DNA binding activity for FOXO1-responsive element on the Fas ligand promoter. Thus, downstream targets induced by FOXOl include Fas ligand and Bcl-2-interacting mediator of cell death (Bim) in the brain ischemia. Accumulating evidence documented how FOXO activation is involved in the mechanisms of ischemic cell death. In this chapter, we document the activation mechanism of FOXO factors following brain ischemia and deline their downstream targets underlying neuronal death. The pathophysiological relevance of crosstalk between FOXOs and calcineurmn pathways is also discussed. Finally, we propose therapeutic perspectives to rescue neurons from delayed neuronal death by promoting the Akt signaling. Vanadium compounds, protein tyrosine phosphatase inhibitor, up-regulates Akt activity in the brain and thereby rescues neurons from delayed neuronal death by inhibiting FOXO-dependent and -independent death signals in neurons.

    To investigate the prognostic factors relevant to sudden sensorineural hearing loss. The internationally accepted standardized clinical research methods, unified design, and unified program were adopted to conduct the prospective clinical multi-center study. The sudden deafness patients between 18 to 65 years old, with the course of this disorder less than two weeks, and without any medical treatments were collected, and then, divided into four types according to the hearing curve: type A, acute sensorineural hearing loss in low tone frequencies; type B, acute sensorineural hearing loss in high tone frequencies; type C, acute sensorineural hearing loss in all frequencies; and type D, total deafness. The factors, in terms of age, gender, type of initial audiogram, time delay before the first visit, and severity of hearing loss, were included in the analyses. A total of 1 024 cases with single side sudden deafness were collected in the study from 33 hospitals in China from August 2007 to October 2011, inclusive of for 492 males (48.05%) and 532 females (51.95%). The average age was (41.2 ± 12.8) years old. There were 553 cases (54.00%) in left ear, and 471 cases (46.00%) in right ear. The curative effects of different types were shown as follows: the type in low tone frequencies had the highest rate of 90.73%, the type in all frequencies was 82.59%; the type of total deafness was 70.29%; and the type in high tone frequencies had the lowest rate of 65.96%. It had significant difference of the effective rate between different types (χ(2) = 231.58, P = 0.000). Age, time delay before first visit, and severity of initial hearing loss were significantly correlated with hearing improvement. Initial audiogram of SSNHL might predict hearing recovery. The young in age and a short time delay before starting treatment are positive prognostic factors for hearing recovery in SSNHL. The initial severity of hearing loss is negative prognostic factor of hearing recovery.

    An efficient indicated prevention of psychotic disorders requires valid risk criteria that work in both clinical and community samples. Yet, ultra-high risk and basic symptom criteria were recently recommended for use in clinical samples only. Their use in the community was discouraged for lack of knowledge about their prevalence, clinical relevance and risk factors in non-clinical, community settings when validly assessed with the same instruments used in the clinic. Using semi-structured telephone interviews with established psychosis-risk instruments, we studied the prevalence of psychosis-risk symptoms and criteria, their clinical relevance (using presence of a non-psychotic mental disorder or of functional deficits as proxy measures) and their risk factors in a random, representative young adult community sample (N=2683; age 16-40 years; response rate: 63.4%). The point-prevalence of psychosis-risk symptoms was 13.8%. As these mostly occurred too infrequent to meet frequency requirements of psychosis-risk criteria, only 2.4% of participants met psychosis-risk criteria. A stepwise relationship underlay the association of ultra-high risk and basic symptoms with proxy measures of clinical relevance, this being most significant when both occurred together. In line with models of their formation, basic symptoms were selectively associated with age, ultra-high risk symptoms with traumatic events and lifetime substance misuse. Psychosis-risk criteria were uncommon, indicating little risk of falsely labelling individuals from the community at-risk for psychosis. Besides, both psychosis-risk symptoms and criteria seem to possess sufficient clinical relevance to warrant their broader attention in clinical practice, especially if ultra-high risk and basic symptoms occur together.

    Articles published in both the American Journal of Community Psychology and Journal of Community Psychology, from their inception in 1973 through 1997, were content analyzed for women relevance, diversity, feminism, and historical change. Overall, 9.8% of the articles reviewed (N = 2,178) were considered women relevant, 4% recognized diversity among women, and 3% were considered feminist. There was an average yearly increase in women-relevant and feminist articles from 7.3 pre-1990 to 11.2 post-1990, and 1.6 pre-1990 to 4.6 post-1990, respectively. Overall, mental health and motherhood were the most addressed content areas. Among feminist articles, gender roles and violence against women were most salient. Race and SES were the most noted issues of diversity in both women-relevant and feminist articles. While an increase in feminist publications by both journals is promising, stereotypes of women and other oppressed groups continue to be perpetuated.

  13. The effects of space relevant environmental factors on halophilic Archaea

    Leuko, Stefan; Moeller, Ralf; Rettberg, Petra

    Within the last 50 years, space technology has provided tools for transporting terrestrial (microbial) life beyond Earth's protective shield in order to study its responses to selected conditions of space. Microorganisms are ubiquitous and can be found in almost every environment on Earth. They thrive and survive in a broad spectrum of environments and are true masters in adapting to rapidly changing external conditions. Although microorganisms cannot actively grow under the harsh conditions of outer space or other known planets, some microorganisms might be able to survive for a time in space or other planets as dormant, inactive spores or in similar desiccation-resistant resting states, e.g., enclosed in halite crystals or biofilms. Halite crystals are the realm of halophilic Archaea as they have adapted to life at extreme salt concentrations. They can stay entrapped in such crystals for millions of years without losing viability and therefore the family Halobacteriaceae belongs to the group of microorganisms which may survive space travel or may even be found on other planets. Several members of this family have been utilized in space relevant experiments where they were exposed to detrimental environmental conditions such as UV-C radiation, vacuum, temperature cycles (+60(°) C and -25(°) C) and heavy iron bombardment (150 MeV He, 500 MeV Ar and 500 MeV Fe ions). The viability was evaluated by colony forming unit (cfu) counts as well as with the LIFE/DEAD kit. Results revealed that UV-C radiation (up to 1.000 J/m (2) ) has a considerable effect on the viability, whereas the other tested parameters inflict little damage onto the organisms. Repair of UV-C inflicted damage is efficient and several DNA damage repair genes are up-regulated following exposure. Halophilic archaea display a strong resistance against heavy iron bombardment, with dosages of up to 2.000 Gy 500 MeV Fe ions needed to establish a visible effect on the vitality.

  17. Community capacity building in practice: constructing its meaning and relevance to health promoters.

    Lovell, Sarah A; Kearns, Robin A; Rosenberg, Mark W

    2011-09-01

    Community capacity building (CCB) is held up as a benchmark for sustainable health promotion, reflecting the empowering discourse of the Ottawa Charter (WHO 1986). In light of concerns that this language may be that of the presiding bureaucratic elite rather than the realities of those working directly with communities (Laverack & Labonte 2000), we question whether CCB reflects the work of New Zealand health promoters. The aim of this study is to assess what CCB means to health promoters and how relevant it is to their work in New Zealand. Focus groups and interviews were carried out with 64 health promoters between January 2008 and March 2009. The results of this qualitative study indicated that, while the terminology of CCB is poorly established in New Zealand, the overwhelming majority of participants felt that, to be an effective health promoter, they needed the buy-in and support of the communities in which they work. As a result, community-driven approaches have emerged as a core component of good health promotion practice in New Zealand. Yet, the concept of CCB was applied loosely with health promoters adopting language and practices corresponding more with the nuances of community development. The limited use of systematic approaches to building community capacity was accompanied by few successes achieving sustainable health promotion programmes. In prioritising community relationships many health promoters were placed in an ideological bind whereby achieving community ownership over health promotion meant compromising the evidence base of their programmes. Academic discussions of CCB appear to have gained little traction into the realm of health promotion practice in New Zealand highlighting the need for relevant research with a strong grounding in practice. © 2011 Blackwell Publishing Ltd.

    2012-01-01

    Microorganisms in membrane bioreactors (MBRs) play important roles on degradation of organic/inorganic substances in wastewaters, while microbial deposition/growth and microbial product accumulation on membranes potentially induce membrane fouling. Generally, there is a need to characterize membrane foulants and to determine their relations to the evolution of membrane fouling in order to identify a suitable fouling control approach in MBRs. This review summarized the factors in MBRs that influence microbial behaviors (community compositions, physical properties, and microbial products). The state-of-the-art techniques to characterize biofoulants in MBRs were reported. The strategies for controlling microbial relevant fouling were discussed and the future studies on membrane fouling mechanisms in MBRs were proposed. PMID:24958297

    Portuguese community pharmacies provide pharmaceutical services, such as therapeutic outcomes follow-up, supplemented by relevant point-of-care testing that require continuity of provision to be effective. To identify factors of technical and communication nature that during a patient interview contribute to patients' loyalty. A cross-sectional descriptive study, with a purposive sample of community pharmacies providing pharmaceutical care, was conducted. Patient interviews were taped and transcribed verbatim. Duration, segments and utterances were identified and time stamped, using a previously validated coding scheme. To identify predictors of loyalty, logistic regression analyses were performed. From 59 interviews, participants' average age was 65.7 years and 42 (71.2%) were female; 45 (76.3%) interviews were classified as outcomes measurements and 14 (23.7%) as pharmaceutical consultations, with 33.2% of the patients booking a following appointment. The significant items to explain loyalty were associated with lifestyle and psychosocial exchange, age of the patient, and the presence of all interview segments (i.e. a complete consultation). Contrary to common professional beliefs and practice orientation it would appear that pharmacists' technical skills are not the essential factors that promote patients' loyalty needed for continuity of care, at least in the same extent as the social and lifestyle-related content of the exchange. Pharmaceutical care education should focus on relational skills as much as on medication-related competencies. Copyright © 2015 Elsevier Inc. All rights reserved.

    Whiplash injury (WI) is commonly evaluated in medico-legal practice. With the aim of knowing the determining factors of WI's medico-legal prognosis, a prospective and observational study was carried out. One hundred and twenty consecutive patients who were clinically observed and evaluated in the Medico-Legal Clinic of Barcelona were studied. Socio-demographic, clinical, radiographic and evolutive factors were analyzed. We included 120 patients with a mean age of 35.6 (14) years (range, 4-74), with a homogeneous male/female distribution. An earlier cervical pathology was detected in 10% of patients; none of them had previous psychiatric pathology. 95% corresponded to road-traffic accident cases and there were 5 aggression cases. Over 50% of cases involved a rear-end collision. All patients had neck pain, almost 25% had headache and 13% had paresthesia. According to the Whiplash Association Disorders clinical classification, distribution in grades (G) was: G I 51%, G II 32% and G III 17%. Patients reported recovery within a mean time of 71.6 (46) days (range, 4-244), with 51,2 (45) no working days (range, 0-180 days). The 52% of the patients rest with complains. According to the recovery time, the following medico-legal prognostic factors were identified: age (p < 0.001), being female (p = 0.001), clinical grade (p < 0.001) and abnormal cervical MRI exploration (p < 0.001). Patients with previous cervical pathology reported more complaints (p = 0.001). In our study, WI affected young people of both sex mainly during rear-end collision. Worst medico-legal prognostic factors were age, being females, severity of initial clinical symptoms, previous cervical pathology and abnormal cervical MRI/CT.

    2015-01-01

    Rationale: Genetic variation plays a significant role in the etiology of sarcoidosis. However, only a small fraction of its heritability has been explained so far. Objectives: To define further genetic risk loci for sarcoidosis, we used the Immunochip for a candidate gene association study of immune-associated loci. Methods: Altogether the study population comprised over 19,000 individuals. In a two-stage design, 1,726 German sarcoidosis cases and 5,482 control subjects were genotyped for 128,705 single-nucleotide polymorphisms using the Illumina Immunochip for the screening step. The remaining 3,955 cases, 7,514 control subjects, and 684 parents of affected offspring were used for validation and replication of 44 candidate and two established risk single-nucleotide polymorphisms. Measurements and Main Results: Four novel susceptibility loci were identified with genome-wide significance in the European case-control populations, located on chromosomes 12q24.12 (rs653178; ATXN2/SH2B3), 5q33.3 (rs4921492; IL12B), 4q24 (rs223498; MANBA/NFKB1), and 2q33.2 (rs6748088; FAM117B). We further defined three independent association signals in the HLA region with genome-wide significance, peaking in the BTNL2 promoter region (rs5007259), at HLA-B (rs4143332/HLA-B*0801) and at HLA-DPB1 (rs9277542), and found another novel independent signal near IL23R (rs12069782) on chromosome 1p31.3. Conclusions: Functional predictions and protein network analyses suggest a prominent role of the drug-targetable IL23/Th17 signaling pathway in the genetic etiology of sarcoidosis. Our findings reveal a substantial genetic overlap of sarcoidosis with diverse immune-mediated inflammatory disorders, which could be of relevance for the clinical application of modern therapeutics PMID:26051272

    This study assesses factors that utilities must address when they integrate intermittent renewable technologies into their power-supply systems; it also reviews the literature in this area and has a bibliography containing more than 350 listings. Three topics are covered: (1) interface (hardware and design-related interconnection), (2) operability/stability, and (3) planning. This study finds that several commonly held perceptions regarding integration of intermittent renewable energy technologies are not valid. Among findings of the study are the following: (1) hardware and system design advances have eliminated most concerns about interface; (2) cost penalties have not occurred at low to moderate penetration levels (and high levels are feasible); and (3) intermittent renewable energy technologies can have capacity values. Obstacles still interfering with intermittent renewable technologies are also identified.

    The primary culture of insect cells often suffers from problems with poor reproducibility in the quality of the final cell preparations. The cellular composition of the explants (cell number and cell types), surgical methods (surgical duration and surgical isolation), and physiological and genetic differences between donors may be critical factors affecting the reproducibility of culture. However, little is known about where biological variation (interindividual differences between donors) ends and technical variation (variance in replication of culture conditions) begins. In this study, we cultured larval fat bodies from the Japanese rhinoceros beetle, Allomyrina dichotoma, and evaluated, using linear mixed models, the effect of interindividual variation between donors on the reproducibility of the culture. We also performed transcriptome analysis of the hemocyte-like cells mainly seen in the cultures using RNA sequencing and ultrastructural analyses of hemocytes using a transmission electron microscope, revealing that the cultured cells have many characteristics of insect hemocytes.

    Exclusive breastfeeding for the first 6 mo of life followed by optimal complementary feeding are critical public health measures for reducing and preventing morbidity and mortality in young children. Clinical factors, such as birth weight, prematurity, and illness, that affect the iron and zinc requirements of younger infants are discussed. Maternal diet and nutritional status do not have a strong effect on the mineral content of human milk, but physiologic changes in milk and the infants' status determine the dependence of the infant on complementary foods in addition to human milk to meet iron and zinc requirements after 6 mo. The nature of zinc absorption, which is suitably characterized by saturation response modeling, dictates that plant-based diets, which are low in zinc, are associated with low absolute daily absorbed zinc, which is inadequate to meet requirements. Foods with a higher zinc content, such as meats, are much more likely to be sufficient to meet dietary requirements. Current plant-based complementary feeding patterns for older fully breastfed infants in both developed and developing countries pose a risk of zinc deficiency. The strong rationale for the potential benefits of providing meat as an early complementary food, and the examples of successful intervention programs, provide potent incentives to pursue broader implementation programs, with concurrent rigorous evaluation of both efficacy and effectiveness.

    Background: Gender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females. Methods: A total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2nd or 3rd days, 14th days, and 28th days, respectively. Serum estradiol (E2) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above. Results: In young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (χ2 = 6.35, P = 0.042). The vision during the 14th and 28th day was higher compared to that on the 2nd or 3rd days (P = 0.021). Serum E2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E2 levels reached its maximum value on the 14th day and the minimum value on the 2nd or 3rd day. Conclusions: In adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage. PMID:25698200

  6. Community factors supporting child mental Health.

    PubMed

    Earls, F

    2001-10-01

    A principal purpose of this article has been to examine the gap between research and practice in relation to community factors in child mental health. Two caveats were introduced in preparation for this assessment. First, it was pointed out that the definition of communities has been expanded by considering the organizing properties of social aggregates that are not simply a function of the race, ethnicity, or social class of individuals who compose them. Having these definitions grounded in theory substantially advances the needs of research and the design and goals of community-level interventions. The second caveat relates to the boundaries of the disciplines that cater to the needs of children. During the same era when child psychiatry is largely occupied with placing psychotropic medications at the center of clinical approaches, there is an important effort in child psychology and sociology to cut across their disciplinary confines to form more comprehensive designs that are sensitive to experiences and circumstances that emerge from specific aspects of community context. Research from the PHDCN was used as an example of this new interdisciplinary approach. Several community-based research projects were selected for review based on their clear implications to improve context-sensitive assessment of child mental health and design effective community-based interventions to improve child mental health. The Healthy Start and CATCH programs indicate that involving child professionals at the grassroots of community life requires skill and patience but that the effort is satisfying and potentially effective. Other examples, exemplified by North Carolina's Smart Start initiative and the program of developmental assets from the Search Institute, demonstrate coherent approaches that provide a foundation for long-term capacity building in assessment, local decision making, and the design and evaluation of interventions. Three conclusions are warranted from this

    Background Meandering main pancreatic duct (MMPD), which comprises loop type and reverse-Z type main pancreatic duct (MPD), has long been discussed its relation to pancreatitis. However, no previous study has investigated its clinical significance. We aimed to determine the non-biased prevalence and the effect of MMPD on idiopathic pancreatitis using non-invasive magnetic resonance (MR) technique. Methods and Findings A cross-sectional study performed in a tertiary referral center. The study enrolled 504 subjects from the community and 30 patients with idiopathic pancreatitis (7 acute, 13 chronic, and 10 recurrent acute). All subjects underwent MR scanning and medical examination. MMPD was diagnosed when the MPD in the head of pancreas formed two or more extrema in the horizontal direction on coronal images of MR cholangiopancreatography, making a loop or a reverse-Z shaped hairpin curves and not accompanied by other pancreatic ductal anomaly. Statistical comparison was made among groups on the rate of MMPD including loop and reverse-Z subtypes, MR findings, and clinical features. The rate of MMPD was significantly higher for all idiopathic pancreatitis/idiopathic recurrent acute pancreatitis (RAP) (20%/40%; P<0.001/0.0001; odds ratio (OR), 11.1/29.0) than in the community (2.2%) but was not higher for acute/chronic pancreatitis (14%/8%; P = 0.154/0.266). Multiple logistic regression analysis revealed MMPD to be a significant factor that induces pancreatitis/RAP (P<0.0001/0.0001; OR, 4.01/26.2). Loop/reverse-Z subtypes were found more frequently in idiopathic RAP subgroup (20%/20%; P = 0.009/0.007; OR, 20.2/24.2) than in the community (1.2%/1.0%). The other clinical and radiographic features were shown not associated with the onset of pancreatitis. Conclusions MMPD is a common anatomical variant and might be a relevant factor to the onset of idiopathic RAP. PMID:22655061

    Patients' age and concomitant diseases are relevant for the development and treatment outcome of pneumonia. To establish the frequency and relevance of concomitant diseases in patients over 65 years of age hospitalized for community acquired pneumonia. The research included 550 patients hospitalized at the Institute for Pulmonary Diseases of Vojvodina in Sremska Kamenica due to community acquired pneumonia. Data on concomitant diseases and mortality rate was correlated with the patients' age limit of 65 years, and then statistically analyzed and presented in tables. There were 446 (81.45%) patients under and 102 (18.55%) over the age of 65 years. Dyspnea, impaired consciousness, cyanosis, tachycardia and arterial hypertension were significantly more common in patients over 65 years of age, who also had a higher prognostic score. Mortality was significantly higher (21.6% vs. 6.0%) in the patients aged over 65 years (p < 0.001). Concomitant diseases were significantly more common (p < 0.001) among the patients over 65 years (94.1% vs. 69.2%), and the majority of the elderly patients had two or three comorbidities. The following comorbidities were significantly more common among the patients aged over 65 years: chronic obstructive disease, bronchiectasis, compensated and decompensated cardiomyopathy, cardiac arrhythmia, arterial hypertension and diabetes mellitus. The higher number of concomitant diseases was associated with a significantly elevated hospital mortality (p < 0.001). A statistically significant mortality rate difference was found in both age groups regarding the comorbidity of chronic obstructive disease and decompensated cardiomyopathy. The patients aged over 65 years hospitalized due to community acquired pneumonia had a statistically significantly higher prognostic score, mortality rate and concomitant diseases than the patients below 65 yeas of age. Most subjects of the older group of patients had two or three comorbidities. Concomitant diseases

    Health message sponsorship at community sport and arts events is an established component of a health promotion settings approach. Recent increases in commercial sponsorship of sport and community events has swelled competition for consumer attention and potentially reduced the impact of health message sponsorship. The purpose of this study was to evaluate awareness, understandings and behavioural intentions of health messages promoted at sponsored community sport and arts events. Interview and self-administered surveys were completed by 2259 adults attending one of 29 sport and arts events held in Western Australia between 2008 and 2013. The surveys measured participant awareness of the health message promoted at the event, as well as comprehension, acceptance and behavioural intention as a result of exposure to health messages. Awareness of the sponsored health message was 58% across all sponsored events, with high levels of comprehension (74%) and acceptance (92%) among those aware of the health message. Forming behavioural intentions was significantly related to the type of sponsored message promoted at the event, being female and over 40 years of age. Messages about sun protection and promoting mental health were the most likely to result in behavioural intention. Health message sponsorship, at least within a comprehensive sponsorship program, appears to remain an effective health promotion strategy for generating awareness and behavioural intention among people attending sport and arts events. Remaining relevant within a modern sponsorship environment appears closely aligned to selecting health messages that promote behavioural action relevant to the sponsored event that are also supported by broader health promotion campaigns.

    2014-09-01

    Reliable estimation of sewage flow rates is essential for the proper design of sewers, pumping stations, and treatment plants. The design of the various components of the sewerage system should be based on the most critical flow rates with a focus on extremely low and peak flow rates that would be sustained for a duration related to the acceptable limits of behavior of the components under consideration. The extreme flow conditions and to what extent they differ from the average values are closely related to the size of the community or network, and the socioeconomic conditions. A single pumping station is usually sufficient to pump flow from small community in either flat or non-undulating topography. Therefore, the hydraulic loading on the wastewater treatment plant (WWTP) results from the pumped flow from the pumping station rather than the trunk sewer flow. The intermittent operation of the pumping units further accentuates the sewage hydrograph in the final trunk sewer. Accordingly, the design flow for the various components of the WWTP should be determined based on their relevant flow factors. In this study, analysis of one representative small community out of five monitored small communities in Egypt and the Kingdom of Saudi Arabia is presented. Pumped sewage flow rates were measured and the sewer incoming flows were hydraulically derived. The hourly and daily sewer and pumped flow records were analyzed to derive the relationship between the flow factors that would be sustained for various durations (instantaneously, 1 h, 2 h, etc.) and their probability of non-exceedance. The resulting peaking factors with a consideration for their sustained flow duration and specified probability would permit the design of the various components of the treatment plant using more accurate critical flows.

    Objective To examine the relationship between community factors and hospital readmission rates. Data Sources/Study Setting We examined all hospitals with publicly reported 30-day readmission rates for patients discharged during July 1, 2007, to June 30, 2010, with acute myocardial infarction (AMI), heart failure (HF), or pneumonia (PN). We linked these to publicly available county data from the Area Resource File, the Census, Nursing Home Compare, and the Neilsen PopFacts datasets. Study Design We used hierarchical linear models to assess the effect of county demographic, access to care, and nursing home quality characteristics on the pooled 30-day risk-standardized readmission rate. Data Collection/Extraction Methods Not applicable. Principal Findings The study sample included 4,073 hospitals. Fifty-eight percent of national variation in hospital readmission rates was explained by the county in which the hospital was located. In multivariable analysis, a number of county characteristics were found to be independently associated with higher readmission rates, the strongest associations being for measures of access to care. These county characteristics explained almost half of the total variation across counties. Conclusions Community factors, as measured by county characteristics, explain a substantial amount of variation in hospital readmission rates. PMID:24712374

    We report the social marketing strategies used for the design, recruitment and retention of participants in a community-based physical activity (PA) intervention, Madres para la Salud (Mothers for Health). The study example used to illustrate the use of social marketing is a 48-week prescribed walking program, Madres para la Salud (Mothers for Health), which tests a social support intervention to explore the effectiveness of a culturally specific program using ‘bouts’ of PA to effect the changes in body fat, fat tissue inflammation and postpartum depression symptoms in sedentary Hispanic women. Using the guidelines from the National Benchmark Criteria, we developed intervention, recruitment and retention strategies that reflect efforts to draw on community values, traditions and customs in intervention design, through partnership with community members. Most of the women enrolled in Madres para la Salud were born in Mexico, largely never or unemployed and resided among the highest crime neighborhoods with poor access to resources. We developed recruitment and retention strategies that characterized social marketing strategies that employed a culturally relevant, consumer driven and problem-specific design. Cost and benefit of program participation, consumer-derived motivation and segmentation strategies considered the development transition of the young Latinas as well as cultural and neighborhood barriers that impacted retention are described.

    The trillions of bacterial cells that colonize the mammalian digestive tract influence both host physiology and the fate of dietary compounds. Gnotobionts and fecal transplantation have been instrumental in revealing the causal role of intestinal bacteria in energy homeostasis and metabolic dysfunctions such as type-2 diabetes. However, the exact contribution of gut bacterial metabolism to host energy balance is still unclear and knowledge about underlying molecular mechanisms is scant. We have previously characterized cecal bacterial community functions and host responses in diet-induced obese mice using omics approaches. Based on these studies, we here discuss issues on the relevance of mouse models, give evidence that the metabolism of cholesterol-derived compounds by gut bacteria is of particular importance in the context of metabolic disorders and that dominant species of the family Coriobacteriaceae are good models to study these functions.

    A cross-sectional health examination survey was carried out among a random sample of 406 people of 30 years and above from a rural community to investigate the prevalence of coronary heart disease risk factors. Prevalence of smoking and tobacco use was 16%, alcohol intake 9.4 %, daily Salt intake (> or = 5 gram) 34.2%, daily saturated fat intake ( > or =10 % of daily energy intake) 47.0 % and physical inactivity 18.5 %. BMI was > or =25 Kg /m(2) in 18 percent and it was > or =30 Kg / m(2) in 3.2 percent population. Truncal obesity (WHR: men> 0.9; women > 0.8) was found 18.5 percent more in case of males (20.7). Abdominal obesity(men > or =102; women > or = 88)was found 15.7 percent more in case of males (20.6).18.5 percent population was found suffering from systolic hypertension> or =140 mm Hg )and 15 percent from diastolic hypertension(> or =90 mm Hg). Awareness of CHD risk factors was present in 30.0 percent population. Differences in prevalence of riskfactor in male and female were found statistically significant in case of smoking, alcohol consumption and abdominal obesity. The present study shows that prevalence of CHD risk factors increases significantly in men and women having BMI equal or more than 25 Kg /m(2) so this cutoff, should be used to determine obesity in Indian population.

    Future climate scenarios in the Baltic Sea project an increase of cyanobacterial bloom frequency and duration, attributed to eutrophication and climate change. Some cyanobacteria can be toxic and their impact on ecosystem services is relevant for a sustainable sea. Yet, there is limited understanding of the mechanisms regulating cyanobacterial diversity and biogeography. Here we unravel successional patterns and changes in cyanobacterial community structure using a 2-year monthly time- series during the productive season in a 100 km coastal-offshore transect using microscopy and high-throughput sequencing of 16S rRNA gene fragments. A total of 565 cyanobacterial OTUs were found, of which 231 where filamentous/colonial and 334 picocyanobacterial. Spatial differences in community structure between coastal and offshore waters were minor. An “epidemic population structure” (dominance of asingle cluster) was found for Aphanizomenon/Dolichospermum within the filamentous/colonial cyanobacterial community. In summer, this clusters imultaneously occurred with opportunistic clusters/OTUs, e.g., Nodularia spumigena and Pseudanabaena. Picocyanobacteria, Synechococcus/Cyanobium, formeda consistent but highly diverse group. Overall, the potential drivers structuring summer cyanobacterial communities were temperature and salinity. However, the different responses to environmental factors among and within genera suggest high niche specificity for individual OTUs. The recruitment and occurrence of potentially toxic filamentous/colonial clusters was likely related to disturbance such as mixing events and short-term shifts in salinity, and not solely dependent on increasing temperature and nitrogen-limiting conditions. Nutrients did not explain further the changes in cyanobacterial community composition. Novel occurrence patterns were identified as a strong seasonal succession revealing a tight coupling between the emergence of opportunistic picocynobacteria and the bloom

    The assembling of bacterial communities in conventional activated sludge (CAS) bioreactors was thought, until recently, to be chaotic and mostly unpredictable. Studies done over the last decade have shown that specific, and often, predictable random and non-random factors could be responsible for that process. These studies have also motivated a “structure–function” paradigm that is yet to be resolved. Thus, elucidating the factors that affect community assembly in the bioreactors is necessary for predicting fluctuations in community structure and function. For this study activated sludge samples were collected during a one-year period from two geographically distant CAS bioreactors of different size. Combining community fingerprinting analysis and operational parameters data with a robust statistical analysis, we aimed to identify relevant links between system performance and bacterial community diversity and dynamics. In addition to revealing a significant β-diversity between the bioreactors’ communities, results showed that the largest bioreactor had a less dynamic but more efficient and diverse bacterial community throughout the study. The statistical analysis also suggests that deterministic factors, as opposed to stochastic factors, may have a bigger impact on the community structure in the largest bioreactor. Furthermore, the community seems to rely mainly on mechanisms of resistance and functional redundancy to maintain functional stability. We suggest that the ecological theories behind the Island Biogeography model and the species-area relationship were appropriate to predict the assembly of bacterial communities in these CAS bioreactors. These results are of great importance for engineers and ecologists as they reveal critical aspects of CAS systems that could be applied towards improving bioreactor design and operation.

    2011-09-01

    Most of the experimental work on the effects of ocean acidification on the photosynthesis of algae has been performed in the laboratory using monospecific cultures. It is frequently assumed that the information obtained from these cultures can be used to predict the acclimation response in the natural environment. CO(2) concentration is known to regulate the expression and functioning of the CCMs in the natural communities; however, ambient CO(2) can become quite variable in the marine ecosystems even in the short- to mid-term. We propose that the degree of saturation of the photosynthesis for a given algal community should be defined in relation to the particular characteristics of its habitat, and not only in relation to its taxonomic composition. The convenience of high CO(2) experiments to infer the degree of photosynthesis saturation by CO(2) in the natural algal communities under the present ocean conditions, as well as its trend in a coming future is discussed taking into account other factors such as the availability of light and nutrients, and seasonality.

    The objective of this study is to develop a culturally relevant community based intervention for children with communication disabilities in Kenya through a community/researcher partnership. The resulting intervention is for use in a randomized control trial which will be reported at a later stage. Using a qualitative approach, initial data was collected through focus group discussions with women, disabled people and traditional dancers. The groups examined the needs, problems and challenges faced by disabled children and their families. This generated the content and structure for a series of participatory workshops with a further two women’s groups. These workshops strove to generate a culturally relevant community based intervention programme for children with communication disabilities and their families. The content and balance of the resulting intervention was observed to be different from existing programmes described in the literature. Notably it included many culturally appropriate strategies for increasing social integration and raising community awareness. The process of generating a locally relevant community based rehabilitation intervention is potentially transferable and has particular relevance to the estimated 80% of the world where there are no formal rehabilitation services for children with disabilities and where women’s groups are a strong element of local culture.

    This review sought to better understand the issues and challenges experienced by community nurses working in rural areas and how these factors shape their role. Databases were searched to identify relevant studies, published between 1990 and 2015, that focussed on issues and challenges experienced by rural community nurses. Generic and grey literature relating to the subject was also searched. The search was systematically conducted multiple times to assure accuracy. A total of 14 articles met the inclusion criteria. This critical review identified common issues impacting community nursing and included role definition, organisational change, human resource, workplace and geographic challenges. Community nurses are flexible, autonomous, able to adapt care to the service delivery setting, and have a diversity of knowledge and skills. Considerably more research is essential to identify factors that impact rural community nursing practice. In addition, greater advocacy is required to develop the role.

  18. Clinically relevant heterotopic ossification after elbow fracture surgery: a risk factors study.

    PubMed

    2015-04-01

    Heterotopic ossification (HO) is a common complication of elbow fracture surgery that can significantly impair function and range of motion (ROM). Whereas numerous studies have assessed HO after hip trauma or replacement surgery, few data have been reported on the prevalence and risk factors of HO after elbow fractures. Our objective was to investigate the prevalence and risk factors of clinically relevant HO after elbow fracture surgery under the hypothesis that the ability to identify high-risk patients would improve treatment tailoring and assist in meeting patient expectations. We retrospectively included consecutive patients who had surgery for elbow injuries between January 2007 and December 2011. Patient demographics, operative details, and radiographs were reviewed. Of 124 elbows in 122 patients, 38 (30.6%) had HO and 26 (21%) clinically relevant HO. The prevalence of clinically relevant HO was highest in floating elbow injury, followed by combined olecranon and radial head fractures, types A and B distal humerus fractures, and terrible triad injury. By multiple logistic regression, factors that independently predicted clinically relevant HO were fracture-dislocation (OR, 4.87; 95%CI, 1.78-13.29; P=0.002) and longer time to surgery (P<0.05). Of the 26 patients with clinically relevant HO, 6 (23%) eventually required revision elbow surgery to improve ROM. HO of the elbow occurred in almost one-third of our patients with surgically treated elbow fractures. Fracture-dislocation of the elbow and longer time to surgery independently predicted HO responsible for ROM loss. Clinically relevant HO was associated with significant morbidity.

  19. Uncovering community structures with initialized Bayesian nonnegative matrix factorization.

    PubMed

    Tang, Xianchao; Xu, Tao; Feng, Xia; Yang, Guoqing

    2014-01-01

    Uncovering community structures is important for understanding networks. Currently, several nonnegative matrix factorization algorithms have been proposed for discovering community structure in complex networks. However, these algorithms exhibit some drawbacks, such as unstable results and inefficient running times. In view of the problems, a novel approach that utilizes an initialized Bayesian nonnegative matrix factorization model for determining community membership is proposed. First, based on singular value decomposition, we obtain simple initialized matrix factorizations from approximate decompositions of the complex network's adjacency matrix. Then, within a few iterations, the final matrix factorizations are achieved by the Bayesian nonnegative matrix factorization method with the initialized matrix factorizations. Thus, the network's community structure can be determined by judging the classification of nodes with a final matrix factor. Experimental results show that the proposed method is highly accurate and offers competitive performance to that of the state-of-the-art methods even though it is not designed for the purpose of modularity maximization.

    Objectives. Using a community-based participatory research approach, a tribe–university team conducted a formative assessment of local factors that influence youth wellness to guide the design of a culturally and locally relevant health promotion program. Methods. Open-ended interviews with key informants, a school self-assessment using the Centers for Disease Control’s School Health Index, and a locally generated environmental inventory provided data that were triangulated to yield a composite of influential factors and perceived need within the community. Results. Family involvement and personal goal setting were identified as key to youth wellness. Supportive programs were described as having consistent adult leadership, structured activities, and a positive local and regional image. Availability of illicit drugs and alcohol, poor teacher attitude, and lack of adult involvement were significant negative factors that impact youth behavior. Conclusions. Local/native (emic) and university/nonnative (etic) perspectives and abilities can be combined to yield a culturally relevant formative assessment that is useful to public health planning. In this collaborative effort, standard means of data collection and analysis were modified in some cases to enhance and build upon the knowledge and skills of community researchers. PMID:16873759

  5. [Antibiotic therapy for community acquired Streptococcus pneumoniae pneumonia: clinical relevance of antibiotic resistance].

    PubMed

    Bédos, J-P; Bruneel, F

    2006-01-01

    The emergence of Streptococcus pneumoniae strains with reduced susceptibility to beta-lactams and with multiple drug resistance has not led to major changes in recommendations for antibiotic therapy in patients with acute community-acquired pneumococcal pneumonia. Numerous factors explain the limited clinical impact of this major microbiological change. The frequency of intermediate strains is high but the frequency of resistant strains to beta-lactams is very low. There is a complex relation between the acquisition of resistance to beta-lactams and the decreased virulence of S. pneumoniae strains. The only finding in studies of humanized experimental animal models of lethal bacteremic pneumonia caused by resistance and tolerant strains was a slowing in the kinetics of beta-lactams bactericidal activity, especially for amoxicillin. Taken together, this preclinical data shows that microbiological resistance of pneumococci to beta-lactams has very little influence on a possible failure of recommanded treatment regimens for pneumococcal pneumonia. The high rate of multiple drug resistance, particularly among beta-lactam resistant strains, rules out the probabilistic use of macrolides. Conversely, fluoroquinolone (FQ) resistance remains low, inferior to 3%, and the same is true for ketolides (<1%). Only a global strategy of patient management in the use of these new drugs could ensure their long-term activity. The high mortality rate of hospitalized S. pneumoniae pneumonia will only be improved with a better understanding of the complex host-bacteria interactions.

    To understand time-evolving networks, researchers should not only concentrate on the community structures, an essential property of complex networks, in each snapshot, but also study the internal evolution of the entire networks. Temporal communities provide insights into such mechanism, i.e., how the communities emerge, expand, shrink, merge, split and decay over time. Based on the symmetric nonnegative matrix factorization (SNMF), we present a dynamic model to detect temporal communities, which not only could find a well community structure in a given snapshot but also demands the results bear some similarity to the partition obtained from the previous snapshot. Moreover, our method can handle the situation that of the number of community changes in the networks. Also, a gradient descent algorithm is proposed to optimize the objective function of the model. Experimental results on both the synthetic and real-world networks indicate that our method outperforms the state-of-art methods for temporal community detection.

    Although acute stroke care has improved survival, many individuals report dissatisfaction with community reintegration after stroke. The aim of this qualitative meta-synthesis was to examine the barriers and facilitators of community reintegration in the first year after stroke from the perspective of people with stroke. A systematic literature search was conducted. Papers that used qualitative methods to explore the experiences of individuals with stroke around community reintegration in the first year after stroke were included. Two reviewers independently assessed the methodological quality of papers. Themes, concepts and interpretations were extracted from each study, compared and meta-synthesised. From the 18 included qualitative studies four themes related to community reintegration in the first year after stroke were identified: (i) the primary effects of stroke, (ii) personal factors, (iii) social factors and (iv) relationships with professionals. This review suggests that an individual's perseverance, adaptability and ability to overcome emotional challenges can facilitate reintegration into the community despite persisting effects of their stroke. Appropriate support from family, friends, the broader community and healthcare professionals is important. Therapeutic activities should relate to meaningful activities and should be tailored to the individual stroke survivor. Stroke survivors feel that rehabilitation in familiar environments and therapeutic activities that reflect real-life could help their community re-integration. In addition to the physical sequelae of stroke, emotional consequences of stroke should be addressed during rehabilitation. Healthcare professionals can provide clear and locally relevant advice to facilitate aspects of community reintegration, including the return to driving and work.

    Many bacteria can develop biofilm (BF), a multicellular structure largely combining bacteria and their extracellular polymeric substances (EPS). The formation of biofilm results in an alternative existence in which microbes ensure their survival in adverse environments. Biofilm-relevant infections are more persistent, resistant to most antibiotics, and more recalcitrant to host immunity. Mycobacterium tuberculosis, the causative agent of tuberculosis, can develop biofilm, though whether M. tuberculosis can form biofilm within tuberculosis patients has yet to be determined. Here, we summarize the factors involved in the development and dispersal of mycobacterial biofilms, as well as underlying regulatory factors and inhibitors against biofilm to deepen our understanding of their development and to elucidate potential novel modes of action for future antibiotics. Key factors in biofilm formation identified as drug targets represent a novel and promising avenue for developing better antibiotics.

    Factors relating to the airport-community noise problem are discussed herein. The noise problems are associated with aircraft landing approaches, take-offs, and climbouts in communities near commercial airports. The main objectives are to identify the significant factors involved in the problem, to define some of their interrelationships, and to present recent related research information from NASA in-house and contract studies. Changes in the types of aircraft power plants, the aircraft operating procedures, and the community itself are all judged to be important; however, these changes should not be made without understanding the associated human-response implications.

    A systems approach has previously been used to follow the response behaviour of Arabidopsis thaliana plants upon sulphur limitation. A response network was reconstructed from a time series of transcript and metabolite profiles, integrating complex metabolic and transcript data in order to investigate a potential causal relationship. The resulting scale-free network allowed potential transcriptional regulators of sulphur metabolism to be identified. Here, three sulphur-starvation responsive transcription factors, IAA13, IAA28, and ARF-2 (ARF1-Binding Protein), all of which are related to auxin signalling, were selected for further investigation. IAA28 overexpressing and knock-down lines showed no major morphological changes, whereas IAA13- and ARF1-BP-overexpressing plants grew more slowly than the wild type. Steady-state metabolite levels and expression of pathway-relevant genes were monitored under normal and sulphate-depleted conditions. For all lines, changes in transcript and metabolite levels were observed, yet none of these changes could exclusively be linked to sulphur stress. Instead, up- or down-regulation of the transcription factors caused metabolic changes which in turn affected sulphur metabolism. Auxin-relevant transcription factors are thus part of a complex response pattern to nutrient starvation that serve as coordinators of the metabolic shifts driving sulphur homeostasis rather then as direct effectors of the sulphate assimilation pathway. This study provides the first evidence ever presented that correlates auxin-related transcriptional regulators with primary plant metabolism. PMID:18596113

  14. Review of biological factors relevant to import risk assessments for epizootic ulcerative syndrome (Aphanomyces invadans).

    2012-02-01

    Epizootic ulcerative syndrome (EUS) is a disease affecting both wild and farmed fish in freshwater and estuarine environments. After it was first described in Japan in 1971, the disease has spread widely across Asia and to some regions of Australia, North America and Africa. In Asia and Africa, the spread of the disease has substantially affected livelihoods of fish farmers and fishermen. No reports are yet published showing the presence of the disease in Europe or South America. Given its epizootic nature and its broad susceptible fish species range, it would appear that the disease has the potential for further spread. This study provides a review of the scientific literature on several biological factors of the pathogen, Aphanomyces invadans, associated with the disease EUS and aspects of the disease that are relevant to undertaking import risk assessments (IRA) covering (i) Life cycle and routes of transmission; (ii) Minimum infectious dose; (iii) Tissue localization and pathogen load; (iv) Predisposing factors for infection and factors influencing expression of disease; (v) Carrier state in fish; (vi) Diagnostic methods; (vii) Survival in the environment; (viii) Permissive temperature range; (ix) Stability of the agent in aquatic animal products; (x) Prevalence of infection; and (xi) Affected life stages. Much of the biological information presented is relevant to a broad range of risk questions. Areas where data are lacking were identified, and the information provided is put into context with other aspects that need to be addressed in an IRA. © 2011 Crown copyright.

    The development of high-throughput sequencing methods allows for the characterization of microbial communities in a wide range of environments on an unprecedented scale. However, insight into microbial community composition is limited by our ability to detect patterns in this flood of sequences. Here we compare the performance of 51 analysis techniques using real and simulated bacterial 16S rRNA pyrosequencing datasets containing either clustered samples or samples arrayed across environmental gradients. We find that many diversity patterns are evident with severely undersampled communities, and that methods vary widely in their ability to detect gradients and clusters. Chi-squared distances and Pearson correlation distances perform especially well for detecting gradients, while Gower and Canberra distances perform especially well for detecting clusters. These results also provide a basis for understanding tradeoffs between number of samples and depth of coverage, tradeoffs which are important to consider when designing studies to characterize microbial communities.

    Background Asthma burden in the US is not evenly distributed. Although asthma prevalence varies widely across urban neighborhoods, little attention has been paid to the community as a key contributor. Objective To determine the effect of positive socio-environmental community factors on childhood asthma prevalence in Chicago. Methods From 2003–2005, an asthma screening survey was conducted among children attending Chicago Public/Catholic K-8 schools. One hundred five schools participated, yielding a stratified representation of 4 race-income groups. Positive community factors, such as social capital, economic potential and community amenities, were assessed using the Metro Chicago Information Center’s Community Vitality Index. Results Of the surveys returned, 45,177 (92%) were geocoded into 287 neighborhoods. Neighborhoods were divided into quartile groups by asthma prevalence (mean: 8%, 12%, 17%, 25%). Community vitality (54% vs. 44%, p<0.0001) and economic potential (64% vs. 38%, p<0.0001) were significantly higher in neighborhoods with low asthma prevalence. Neighborhood interaction (36% vs. 73%, p<0.0001) and stability (40% vs. 53%, p<0.0001) were significantly higher in neighborhoods with high asthma prevalence. Overall, positive factors explained 21% of asthma variation. Childhood asthma increased as the Black population increased in a community (p<0.0001). Accordingly, race/ethnicity was controlled. In Black neighborhoods, these factors remained significantly higher in neighborhoods with low asthma prevalence. When considered alongside socio-demographic/individual characteristics, overall community vitality as well as social capital continued to contribute significantly to asthma variation. Conclusion Asthma prevalence in Chicago is strongly associated with socio-environmental factors thought to enrich a community. A deeper understanding of this impact may lend insight into interventions to reduce childhood asthma. PMID:19450873

    Discovery of communities in complex networks is a fundamental data analysis problem with applications in various domains. While most of the existing approaches have focused on discovering communities of nodes, recent studies have shown the advantages and uses of link community discovery in networks. Generative models provide a promising class of techniques for the identification of modular structures in networks, but most generative models mainly focus on the detection of node communities rather than link communities. In this work, we propose a generative model, which is based on the importance of each node when forming links in each community, to describe the structure of link communities. We proceed to fit the model parameters by taking it as an optimization problem, and solve it using nonnegative matrix factorization. Thereafter, in order to automatically determine the number of communities, we extend the above method by introducing a strategy of iterative bipartition. This extended method not only finds the number of communities all by itself, but also obtains high efficiency, and thus it is more suitable to deal with large and unexplored real networks. We test this approach on both synthetic benchmarks and real-world networks including an application on a large biological network, and compare it with two highly related methods. Results demonstrate the superior performance of our approach over competing methods for the detection of link communities.

    Elderly patients are at increased risk for peptic ulcer and cancer. Predictive factors of relevant endoscopic findings at upper endoscopy in the elderly are unknown. This was a post hoc analysis of a nationwide, endoscopic study. A total of 3,147 elderly patients were selected. Demographic, clinical, and endoscopic data were systematically collected. Relevant findings and new diagnoses of peptic ulcer and malignancy were computed. Both univariate and multivariate analyses were performed. A total of 1,559 (49.5%), 213 (6.8%), 93 (3%) relevant findings, peptic ulcers, and malignancies were detected. Peptic ulcers and malignancies were more frequent in >85-year-old patients (OR 3.1, 95% CI = 2.0-4.7, p = 0.001). The presence of dysphagia (OR = 5.15), weight loss (OR = 4.77), persistent vomiting (OR = 3.68), anaemia (OR = 1.83), and male gender (OR = 1.9) were significantly associated with a malignancy, whilst overt bleeding (OR = 6.66), NSAIDs use (OR = 2.23), and epigastric pain (OR = 1.90) were associated with the presence of peptic ulcer. Peptic ulcer or malignancies were detected in 10% of elderly patients, supporting the use of endoscopy in this age group. Very elderly patients appear to be at higher risk of such lesions.

    Pediculosis capitis is a problem in children and has worldwide distribution. The aim of the present study was to determine the prevalence of pediculosis degree and its relevant factors in the secondary schools in Hamadan west of Iran. The study was carried out in two phases. A cross-sectional procedure was used to determine the prevalence of pediculosis, and the case study was done to identify the relevant factors to the infestation. Totally, 10841 secondary students were chosen and classified in accordance with the clustering sample. The prevalence of pediculosis was 1.05%. It was 1.27% among the urban student; whereas 0.05% among the rural students. About 2.3% belonged to female students, and 0.11% was pertained to the male students. The greatest amount of infestation prevalence was reported from the schools of urban areas particularly in the public schools of suburbia. Furthermore, the prevalence of infestation was more where some individuals had pediculosis previous history and suffered from head inching. It turned out to be a significant relationship between pediculosis, head itching (P<0.001) and previous history of pediculosis (P<0.001). The prevalence of pediculosis in Hamadan is low, but is more in the areas which are deprived of the access to health facilities. Therefore, there is a need for educational campaigns about danger of infection and regular mass screening at school.

    The clinical relevance of and risk factors associated with errors related to medication administration time were studied. In this explorative study, 66 medication administration rounds were studied on two wards (surgery and neurology) of a hospital. Data on medication errors were collected using the blister collection method. The emptied packaging material of medication was collected after each round and compared with each patient's medication orders. Administration time errors were defined as medication administration (actual intake) occurring more than one hour before or after the prescribed time. Generalized estimating equations analysis was performed to study the correlation between medication administration errors and risk factors. Data from 129 patients were included in the study. Among these 129 patients, 2874 opportunities for error were recorded. The majority of opportunities for error occurred during the 7 a.m. round. Within the 2874 opportunities for errors, 10 administration time errors occurred for medications that might interact with food or another medication. Time of administration (noon and 3 p.m.), route of administration (injection or infusion), and frequency of administration (if necessary) had significant protective effects against the occurrence of administration time errors. The rectal route of administration was associated with a significant increase in the frequency of administration time errors compared with the oral route. A clinically relevant administration time error occurred in 2 cases (0.07%). Analysis of medication administration rounds found time errors to be the most common medication error.

    Background Suicidal behavior (SB) is a major, worldwide health concern. To date there is limited understanding of the associated motivational aspects which accompany this self-initiated conduct. Aims To develop a method for identifying motivational features associated with SB by studying admitted psychiatric patients, and to examine their clinical relevance. Methods By performing a factor analytic study using data obtained from a patient sample exhibiting high suicidality and a variety of SB methods, Motivations for SB Scale (MSBS) was constructed to measure the features. Data included assessments of DSM-IV psychiatric and personality disorders, suicide intent, depressive symptomatology, overt aggression, recent life events (RLEs) and methods of SB, collated from structured interviews. Association of identified features with clinical variables was examined by correlation analyses and MANCOVA. Results Factor analyses elicited a 4-factor solution composed of Interpersonal-testing (IT), Interpersonal-change (IC), Self-renunciation (SR) and Self-sustenance (SS). These factors were classified according to two distinctions, namely interpersonal vs. intra-personal directedness, and the level of assumed influence by SB or the relationship to prevailing emotions. Analyses revealed meaningful links between patient features and clinical variables. Interpersonal-motivations (IT and IC) were associated with overt aggression, low suicidality and RLE discord or conflict, while SR was associated with depression, high suicidality and RLE separation or death. Borderline personality disorder showed association with IC and SS. When self-strangulation was set as a reference SB method, self-cutting and overdose-taking were linked to IT and SS, respectively. Conclusions The factors extracted in this study largely corresponded to factors from previous studies, implying that they may be useful in a wider clinical context. The association of these features with SB-related factors suggests

    2008-08-01

    One thousand nine hundred ninety-five individuals in 20 rural Canadian communities were measured on perceived social cohesion by the three Buckner scale subdimensions: psychological sense of community (PSOC), attraction, and neighboring. Number of household children, income over $20,000, age, birthplace in, and years lived in the community significantly positively influenced PSOC and Attraction. Number of household children (positive for income over $20,000; otherwise negative), income over $40,000, birthplace, and years in the community significantly influenced neighboring. Increased interaction generally increases individuals' social cohesion. As the only significant community variable was being on an island province, individual-oriented policies are recommended to increase cohesion.

However, these algorithms exhibit some drawbacks, such as unstable results and inefficient running times. In view of the problems, a novel approach that utilizes an initialized Bayesian nonnegative matrix factorization model for determining community membership is proposed. First, based on singular value decomposition, we obtain simple initialized matrix factorizations from approximate decompositions of the complex network’s adjacency matrix. Then, within a few iterations, the final matrix factorizations are achieved by the Bayesian nonnegative matrix factorization method with the initialized matrix factorizations. Thus, the network’s community structure can be determined by judging the classification of nodes with a final matrix factor. Experimental results show that the proposed method is highly accurate and offers competitive performance to that of the state-of-the-art methods even though it is not designed for the purpose of modularity maximization.

  3. Community wind power ownership schemes in Europe and their relevance to the United States

    With varying success, the United States and Europe have followed a more or less parallel path of policies to support wind development over the past twenty years. Feed-in laws and tax incentives first popularized in California in the early 1980s and greatly expanded upon in Europe during the 1990s are gradually giving way to market-based support mechanisms such as renewable portfolio standards, which are being implemented in one form or another in ten US states and at least three European nations. At the same time, electricity markets are being liberalized in both the US and Europe, and many electricity consumers are being given the choice to support the development of renewable energy through higher tariffs, both in traditionally regulated and newly competitive markets. One notable area in which wind development in Europe and United States has not evolved in common, however, is with respect to the level of community ownership of wind turbines or clusters. While community ownership of wind projects is unheard of in the United States, in Europe, local wind cooperatives or other participatory business schemes have been responsible for a large share of total wind development. In Denmark, for example, approximately 80% of all wind turbines are either individually or cooperatively owned, and a similar pattern holds in Germany, the world leader in installed wind capacity. Sweden also has a strong wind cooperative base, and the UK has recently made forays into community wind ownership. Why is it that wind development has evolved this way in Europe, but not in the United States? What incremental effect have community-owned wind schemes had on European wind development? Have community-owned wind schemes driven development in Europe, or are they merely a vehicle through which the fundamental driving institutions have been channeled? Is there value to having community wind ownership in the US? Is there reason to believe that such schemes would succeed in the US? If so, which

  4. Relevant factors to consider prior to an investor-owned acquisition of a nonprofit healthcare entity.

    The purpose of this article is to explore the factors that affect the negotiations for an acquisition of a nonprofit system by an investor-owned entity. The recent economic downturn, accompanying credit crisis, and healthcare reform legislation will likely encourage and accelerate the pace of merger and acquisition (M&A) transactions between investor-owned entities and nonprofit hospitals. As many nonprofits are smaller, more financially vulnerable, and more limited in their access to capital than their investor-owned counterparts, nonprofits could be prime targets for investor-owned acquirers during the healthcare reform implementation period. In M&A transactions of this type, the investor-owned acquirer typically is motivated to pursue an acquisition when the deal promises an acceptable return on investment and decreased operating costs from economies of scale. Alternatively, the nonprofit target is typically seeking funding for upgrades to facilities and information technology systems as well as a continued commitment to charity care and managed-care contracting leverage. A successful acquisition of a nonprofit hospital by an investor-owned company requires a careful analysis of relevant tax, economic, and strategic factors prior to closing the deal. This article lists the most significant factors to consider in these deals and explains how these factors should influence the purchase price and postacquisition cash flow.

    The aim of this study was to identify the relevant obstetric factors for cerebral palsy (CP) after 33 weeks' gestation in Japan. This retrospective case cohort study (1:100 cases and controls) used a Japanese national CP registry. Obstetric characteristics and clinical course were compared between CP cases in the Japan Obstetric Compensation System for Cerebral Palsy database and controls in the perinatal database of the Japan Society of Obstetrics and Gynecology born as live singleton infants between 2009 and 2011 with a birth weight ≥ 2,000 g and gestation ≥ 33 weeks. One hundred and seventy-five CP cases and 17,475 controls were assessed. Major relevant single factors for CP were placental abnormalities (31%), umbilical cord abnormalities (15%), maternal complications (10%), and neonatal complications (1%). A multivariate regression model demonstrated that obstetric variables associated with CP were acute delivery due to non-reassuring fetal status (relative risk [RR]: 37.182, 95% confidence interval [CI]: 20.028-69.032), uterine rupture (RR: 24.770, 95% CI: 6.006-102.160), placental abruption (RR: 20.891, 95% CI: 11.817-36.934), and preterm labor (RR: 3.153, 95% CI: 2.024-4.911), whereas protective factors were head presentation (RR: 0.199, 95% CI: 0.088-0.450) and elective cesarean section (RR: 0.236, 95% CI: 0.067-0.828). CP after 33 weeks' gestation in the recently reported cases in Japan was strongly associated with acute delivery due to non-reassuring fetal status, uterine rupture, and placental abruption.

  6. Therapy-relevant factors in adult ADHD from a cognitive behavioural perspective.

    2010-06-01

    Adult individuals with attention-deficit hyperactivity disorder (ADHD) have been suffering from this neurobiological and highly heritable disorder chronically since childhood. Resulting from their longstanding neuropsychological impairments, such as attentional problems, emotional instability, and disinhibition, they are familiar to a multiplicity of negative life outcomes and underachievement. Furthermore, a large part of this population suffers from psychiatric comorbidity. This accumulation of negative experiences has an impact on therapy-relevant factors such as the individual's self-esteem, self-efficacy, development of core beliefs/schemas, and coping strategies. Based on negative beliefs about the self, individuals confronted with difficult situations develop maladaptive coping strategies, for instance avoidance and procrastination. These strategies lead to maintenance and reinforcement of maladaptive beliefs, and as such they acquit themselves as schema-confirming. Captured in this vicious cycle, the individual sees her negative view of the self confirmed. The purpose of this paper is to illuminate these interactive factors that influence the aforementioned cycle in order to emphasize the cognitive behavioural interventions tailored to those factors on the basis of latest research. Furthermore, the authors want to attract notice to the resources people with ADHD are said to have, namely creativity and resilience. These postulated resources could be therapy-relevant by creating positive beliefs about the self, hence improving coping skills and breaking the vicious circle of negative appraisal. Taking into account personal resources and their fostering may be an important fundament for the treatment plan of adult ADHD. Information on the current state of research and theoretical approaches concerning the below-mentioned key words was gathered through MEDLINE, PsycINFO, PSYNDEXplus, and PubMed databases.

  8. Primary health care in rural Malawi - a qualitative assessment exploring the relevance of the community-directed interventions approach

    2012-01-01

    Background Primary Health Care (PHC) is a strategy endorsed for attaining equitable access to basic health care including treatment and prevention of endemic diseases. Thirty four years later, its implementation remains sub-optimal in most Sub-Saharan African countries that access to health interventions is still a major challenge for a large proportion of the rural population. Community-directed treatment with ivermectin (CDTi) and community-directed interventions (CDI) are participatory approaches to strengthen health care at community level. Both approaches are based on values and principles associated with PHC. The CDI approach has successfully been used to improve the delivery of interventions in areas that have previously used CDTi. However, little is known about the added value of community participation in areas without prior experience with CDTi. This study aimed at assessing PHC in two rural Malawian districts without CDTi experience with a view to explore the relevance of the CDI approach. We examined health service providers’ and beneficiaries’ perceptions on existing PHC practices, and their perspectives on official priorities and strategies to strengthen PHC. Methods We conducted 27 key informant interviews with health officials and partners at national, district and health centre levels; 32 focus group discussions with community members and in-depth interviews with 32 community members and 32 community leaders. Additionally, official PHC related documents were reviewed. Results The findings show that there is a functional PHC system in place in the two study districts, though its implementation is faced with various challenges related to accessibility of services and shortage of resources. Health service providers and consumers shared perceptions on the importance of intensifying community participation to strengthen PHC, particularly within the areas of provision of insecticide treated bed nets, home case management for malaria, management of

    Rebamipide with mucin secretagogue activity was recently approved for the treatment of dry eye. The efficacy and safety in the treatment of rebamipide were shown in two pivotal clinical trials. It was the aim of this study to evaluate the effect of 2% rebamipide ophthalmic suspension in patients with dry eye and analyze relevant factors for favorable effects of rebamipide in clinical practice. This was a retrospective cohort study of 48 eyes from 24 patients with dry eye treated with 2% rebamipide ophthalmic suspension. Dry eye-related symptom score, tear film break-up time (TBUT), fluorescein ocular surface staining score (FOS) and the Schirmer test were used to collect the data from patients at baseline, and at 2, 4, 8, and 12 week visits. To determine the relevant factors, multiple regression analyses were then performed. Mean dry eye-related symptom score showed a significant improvement from the baseline (14.5 points) at 2, 4, 8 and 12 weeks (9.80, 7.04, 7.04 and 7.83 points, corrected P value < 0.001, respectively). Median FOS showed a significant improvement from the baseline (3.0 points) at 2, 4, 8 and 12 weeks (2.0, 2.0, 1.0 and 1.0 points, corrected P value < 0.001, respectively). TBUT and Schirmer test values were not significantly improved after the treatment. For ocular symptoms, three parameters (foreign body sensation, dry eye sensation and ocular discomfort) showed significant improvements at all visits. The multiple regression analyses showed that the fluorescein conjunctiva staining score was significantly correlated with the changes of dry eye-related symptom score at 12 weeks (P value = 0.017) and dry eye-related symptom score was significantly correlated with independent variables for the changes of FOS at 12 weeks (P value = 0.0097). Two percent rebamipide ophthalmic suspension was an effective therapy for dry eye patients. Moreover the fluorescein conjunctiva staining score and dry eye-related symptom score might be good relevant factors for

    Marine debris remains a global challenge, with significant impacts on wildlife. Despite this, there is a paucity of research examining public understanding about marine wildlife entanglement [MWE], particularly within an Australian context. The present study surveyed two hundred and thirteen participants across three coastal sites to assess familiarity with MWE and the effectiveness of a new community education initiative 'Seal the Loop' [STL]. Results revealed attitudes toward marine wildlife were very positive (M 40.5, SD 4.12); however 32% of participants were unable to correctly explain what MWE is and risks to wildlife were under-estimated. STL may be one method to enhance public understanding and engagement-if community familiarity with the program can be increased. For those aware of STL (<13% of the sample at the time of the study), findings revealed this was having a positive impact (e.g. learning something new, changed waste disposal behaviours).

    Although a variety of risk factors for mobility limitation in older adults have been examined, a collective review of relevant literature has not been reported. The purposes of this review are to report the intrapersonal, interpersonal, environmental, and organizational risk factors related to mobility limitation using a social ecological perspective and to discuss the direction of future clinical practice consistent with current literature on mobility limitation of community-dwelling older adults. Intrapersonal risk factors related to mobility limitation include advanced age, female gender, low socioeconomic status, comorbidity, lack of motivation (i.e., dependent personality, decreased self-efficacy), lifestyle factors (i.e., sedentary lifestyle, smoking, obesity), and physiological factors (i.e., vitamin D deficiency, inflammation, poor nutritional status). Interpersonal risk factors related to mobility limitation include weak social networks and limited social activities. Geriatric clients may also experience a decline in mobility when they encounter environmental challenges such as an inconvenient home environment and lack of availability of services in their community, as well as lack of organizational resources stemming from social policy. Potential intervention strategies focused on modifiable risk factors may include lifestyle modifications, social networking programs, and enhancing awareness of environmental and organizational resources in the community for older adults at risk for mobility limitation.

    Atypical hemolytic uremic syndrome (aHUS) is a genetic ultrarare renal disease associated with overactivation of the alternative pathway of complement. Four gain-of-function mutations that form a hyperactive or deregulated C3 convertase have been identified in Factor B (FB) ligand binding sites. Here, we studied the functional consequences of 10 FB genetic changes recently identified from different aHUS cohorts. Using several tests for alternative C3 and C5 convertase formation and regulation, we identified two gain-of-function and potentially disease-relevant mutations that formed either an overactive convertase (M433I) or a convertase resistant to decay by FH (K298Q). One mutation (R178Q) produced a partially cleaved protein with no ligand binding or functional activity. Seven genetic changes led to near-normal or only slightly reduced ligand binding and functional activity compared with the most common polymorphism at position 7, R7. Notably, none of the algorithms used to predict the disease relevance of FB mutations agreed completely with the experimental data, suggesting that in silico approaches should be undertaken with caution. These data, combined with previously published results, suggest that 9 of 15 FB genetic changes identified in patients with aHUS are unrelated to disease pathogenesis. This study highlights that functional assessment of identified nucleotide changes in FB is mandatory to confirm disease association. PMID:24652797

    Helicobacter pylori (H. pylori) usually colonizes the gastric mucosa of more than 50% of the human population, causing an infection that may appear in early childhood and can persist for life. H. pylori is suggested as the main cause of peptic ulcer and chronic gastritis. It is also associated with gastric cancer. Its severity and symptoms depend on environmental factors, host susceptibility and bacterial components, which allow H. pylori to switch between commensalism and pathogenicity. H. pylori is genetically highly variable, and the variability which affects H. pylori virulence factors might be useful in identifying the strains with different degrees of pathogenicity. The geographic distribution of distinct H. pylori genotypes is largely unknown and should be established. The prevalence of more pathogenic genotypes in certain areas may have important epidemiological consequences. It also might be associated with the severity of H. pylori related diseases in such regions. Given that Iran is located in the Middle East and Asian populations have revealed high levels of gastric cancer, it is of clinical interest to clarify the potential of H. pylori virulence markers in predicting the associated clinical outcomes. In this review, clinical relevance of adhesion molecules and significant virulence factors of H. pylori in Iranian patients with gastrointestinal diseases are discussed in comparison to other countries.

    2016-03-21

    Determination of the water-leaving radiance LW through above-water radiometry requires knowledge of accurate reflectance factors ρ of the sea surface. Publicly available ρ relevant to above-water radiometry include theoretical data sets generated: i. by assuming a sky radiance distribution accounting for aerosols and multiple scattering, but neglecting polarization, and quantifying sea surface effects through Cox-Munk wave slope statistics; or differently ii. accounting for polarization, but assuming an ideal Rayleigh sky radiance distribution, and quantifying sea surface effects through modeled wave elevation and slope variance spectra. The impact on above-water data products of differences between those factors ρ was quantified through comparison of LW from the Ocean Color component of the Aerosol Robotic Network (AERONET-OC) with collocated LW from in-water radiometry. Results from the analysis of radiance measurements from the sea performed with 40 degrees viewing angle and 90 degrees azimuth offset with respect to the sun plane, indicated a slightly better agreement between above- and in-water LW determined for wind speeds tentatively lower than 4 m s-1 with ρ computed accounting for aerosols, multiple scattering and Cox-Munk surfaces. Nevertheless, analyses performed by partitioning the investigated data set also indicated that actual ρ values would exhibit dependence on sun zenith comprised between those characterizing the two sets of reflectance factors.

    Treatments that target the androgen axis represent an effective strategy for patients with advanced prostate cancer, but the disease remains incurable and new therapeutic approaches are necessary. Significant advances have recently occurred in our understanding of the growth factor and signaling pathways that are active in prostate cancer. In conjunction with this, many new targeted therapies with sound preclinical rationale have entered clinical development and are being tested in men with castration-resistant prostate cancer. Some of the most relevant pathways currently being exploited for therapeutic gain are HGF/c-Met signaling, the PI3K/AKT/mTOR pathway, Hedgehog signaling, the endothelin axis, Src kinase signaling, the IGF pathway, and angiogenesis. Here, we summarize the biological basis for the use of selected targeted agents and the results from available clinical trials of these drugs in men with prostate cancer.

    Community and neighbourhood structures contribute not only to the health and well-being, but also to the participation of older adults. The degree of participation depends on both the living environment and the individual's personal characteristics, preferences and perception. However, there is still limited empirical evidence on how community and neighbourhood structures are linked to participation and health in the aged population. A qualitative exploratory approach was chosen with a series of problem-centred, semi-structured focus group discussions. Study participants were selected from within the city of Augsburg, Southern Germany, and from two municipalities in surrounding rural districts. The interviews took place in 2013. Structuring content analysis was used to identify key concepts. We conducted 11 focus group discussions with a total of 78 different study participants. The study participants (33 men and 45 women) had a mean age of 74 years (range 65-92 years). Only two study participants lived in an assisted living facility. Of all study participants, 77% lived in urban and 23% in rural areas. We extracted four metacodes ('Usual activities', 'Requirements for participation', 'Barriers to participation' and 'Facilitators for participation') and 15 subcodes. Health and poorly designed infrastructure were mentioned as important barriers to participation, and friendship and neighbourhood cohesion as important facilitators. This qualitative study revealed that poor design and accessibility of municipal infrastructure are major barriers to participation in old age in Germany. Community and neighbourhood structures can be part of the problem but also part of the solution when accessibility and social networks are taken into account.

    Over the last decade, there has been a substantial increase in online education in the health professions, as well as growing recognition that teamwork and collaboration are essential to success. While the impact of students' sense of community on factors such as course satisfaction and retention has been studied among college enrollees in general, there is little research exploring this concept among allied health students. To address this shortcoming, a convenience sample of students enrolled in a large northeastern school of health-related professions was surveyed to gather information on their demographics, curriculum and selected course attributes, perceived instructor teaching perspectives, and sense of community. Univariate analysis indicated that entry-level students experienced a greater sense of community than post-professional students. Multivariate analysis revealed that instructor-determined factors of encouraging discussion, encouraging expression of opinions, and specifying response times best predicted sense of community. With all other variables controlled, perceptions of community were significantly lower in online courses, among students for whom English was their second language, and in courses where instructors were perceived as focused primarily on content delivery. This study supports promoting selected course and instructor-related attributes associated with sense of community in allied health education, with a particular focus on both non-native English speakers and post-professional students. Enhancement of online courses with strategies that increase instructor presence, better engage students, and facilitate interaction also are warranted.

    The purpose of this report is to provide a state-of-the-art review of structural and functional processes in pelagic communities and extrapolate these empirical and theoretical results to L Lake, the once-through cooling reservoir at the Savannah River Plant. Man-made reservoirs differ from natural lakes in their origins, hydrodynamics, sedimentation patterns, and general eutrophication histories. Phosphorus and nitrogen limitation of phytoplankton productivity controls the rate of eutrophication, while also determining algal community structure. Here the Lean and Monod models of nutrient fluxing and uptake kinetics provide useful constructs for predictive purposes. Much of the reduced carbon synthesized by primary production is shunted through the microbial loop where heterotrophic flagellates and protozoans pass this carbon on to the macrozooplankton. This recently discovered pathway is common to eutrophic reservoirs where blue-green species dominate phytoplankton assemblages. Through selective grazing and tactile oriented predation, the crustacean zooplankton partially regulates the relative abundance of algae and microzooplankton species. 194 refs., 10 figs.

  2. Local Factors Determine Plant Community Structure on Closely Neighbored Islands

    Despite the recent popularity of the metacommunity concept, ecologists have not evaluated the applicability of different metacommunity frameworks to insular organisms. We surveyed 50 closely spaced islands in the Thousand-Island Lake of China to examine the role of local (environmental) and regional (dispersal) factors in structuring woody plant assemblages (tree and shrub species) on these islands. By partitioning the variation in plant community structure into local and regional causes, we showed that local environmental conditions, specifically island morphometric characteristics, accounted for the majority of the variation in plant community structure among the studied islands. Spatial variables, representing the potential importance of species dispersal, explained little variation. We conclude that one metacommunity framework–species sorting–best characterizes these plant communities. This result reinforces the idea that the traditional approach of emphasizing the local perspective when studying ecological communities continues to hold its value. PMID:21572960

  3. Challenge of investigating biologically relevant functions of virulence factors in bacterial pathogens.

    2000-01-01

    Recent innovations have increased enormously the opportunities for investigating the molecular basis of bacterial pathogenicity, including the availability of whole-genome sequences, techniques for identifying key virulence genes, and the use of microarrays and proteomics. These methods should provide powerful tools for analysing the patterns of gene expression and function required for investigating host-microbe interactions in vivo. But, the challenge is exacting. Pathogenicity is a complex phenotype and the reductionist approach does not adequately address the eclectic and variable outcomes of host-microbe interactions, including evolutionary dynamics and ecological factors. There are difficulties in distinguishing bacterial 'virulence' factors from the many determinants that are permissive for pathogenicity, for example those promoting general fitness. A further practical problem for some of the major bacterial pathogens is that there are no satisfactory animal models or experimental assays that adequately reflect the infection under investigation. In this review, we give a personal perspective on the challenge of characterizing how bacterial pathogens behave in vivo and discuss some of the methods that might be most relevant for understanding the molecular basis of the diseases for which they are responsible. Despite the powerful genomic, molecular, cellular and structural technologies available to us, we are still struggling to come to grips with the question of 'What is a pathogen?' PMID:10874737

    Metabolic syndrome is related with abdominal fat and with age-related hearing loss (ARHL). In this study, we evaluated the association between a variety of factors relevant to abdominal fat (FRAs) and hearing thresholds. We reviewed retrospectively the medical records of 2,602 subjects aged over 40 years with symmetrical sensorineural hearing loss who underwent abdominal fat computed tomography (CT) scans. Univariate and multivariate linear regression analyses were used to demonstrate the association between each FRA and hearing thresholds at low and high frequencies. Four of 5 FRAs were associated with hearing thresholds at high frequencies in males. All FRAs examined showed a relationship with hearing thresholds at low frequencies in females. Diabetes mellitus (DM) among clinical factors and visceral adipose tissue (VAT) among the 5 FRAs were the most reflective of hearing thresholds in both males and females. We found that FRAs were associated with hearing loss with frequency specific characteristics according to sex and reinforced that DM and VAT is particularly an important role for hearing.

This was used to establish which factors, including application technique (very small, small, medium and large drop-size), crop characteristics (short/tall, thin/dense) and pattern application of the operator (walking towards or away from the treated area) are relevant to the dermal exposure levels of greenhouse applicators. The results showed that the highest exposure by pesticides during field applications in greenhouses, in the climatic conditions and in the crop conditions typical of a southern European country, occurs on the lower legs and front thighs of the applicators. Similar results were obtained by hierarchical cluster analysis (HCA). Drop-size seems to be very important in determining total exposure, while height and density of crops have little influence on total exposure under the conditions of the present study. No pesticide type is a major factor in total exposure. The application of multiple regression analysis (MRA) allowed assessment of the relationships between the pesticide exposure of the less affected parts of the body with the most affected parts.

    To assess the relevance of genetically determined host factors for the prognosis of meningococcal disease, Fc gamma receptor IIA (FcgammaRIIA), the tumor necrosis factor alpha (TNF-alpha) gene promoter region, and plasminogen-activator-inhibitor-1 (PAI-1) gene polymorphisms were studied in 145 patients with meningococcal disease and in 290 healthy controls matched by sex. Distribution of FcgammaRIIA, TNF-alpha, and PAI-1 alleles was not significantly different between patients and controls. Patients with the FcgammaRIIA-R/R 131 allotype scored > or =1 point in the Barcelona prognostic system more frequently than patients with other allotypes (odds ratio, 18.6; 95% confidence interval, 7.1-49.0, P<0.0001), and they had a higher risk of sequelae (odds ratio, 3.5; 95% confidence interval, 1.1-11.7; P=0.03). Fc gamma receptor IIA polymorphism was associated with markers of disease severity, but TNF-alpha and PAI-1 polymorphisms were not.

    The objective of this study is to describe the implementation of community therapy (CT) at a mental health service (MHS); to identify coping strategies and problems experienced by its users and their families; and to analyze CT's contributions to user's social inclusion. The technique of semi-structured interview and CT's assessment sheets were used in this predominantly qualitative study. Family conflicts, insomnia and abandonment were the major problems cited, and several coping strategies were mentioned, such as: family support, religious belief professional help, etc. It was proved that the user's participation on CT have contributed to their social inclusion, as they reported behavioral changes in their interpersonal relationships. This experience has been showing excellent results, for it works with an approach that comprehends neglected social aspects.

    Over the past eight years we have developed and implemented several U.C. Berkeley-based outreach programs that provide opportunities for grades nine through eleven students in the East San Francisco Bay Area to gain skills and understandings that increase their capacity to enroll and perform successfully in science, technology, engineering, and mathematics (STEM) courses in the future, which enhances their capacity to decide to pursue STEM careers. A common element of these programs is the opportunity they provide participants to engage in environmental science research projects that are directly linked to relevant, real-world environmental problems and issues facing their communities. Analysis of evidence gleaned from questionnaires, interviews and specific assessment instruments indicates that these programs have consistently achieved a high degree of success in that they have: significantly increased participants' understanding of the process and nature of science; enhanced their intellectual self-confidence with regard to STEM; developed deeper appreciation of how scientific research can contribute to the maintenance of healthy local environments; developed a greater interest in participating in STEM-related courses of study and after school programs; and improved attitudes toward STEM. These results corroborate recent research studies that indicate a close relationship between educational activities that promote the perception of STEM as being relevant and the ability to foster development of deeper conceptual understandings among teens. Moreover, they support the notion that providing opportunities for students to develop personal connections with particular issues discussed, and real-world STEM experiences that make STEM more relevant and interesting can help to bring about changes in attitude, which is a key component in improving STEM learning and understanding particularly among urban youth. Overall, our work suggests that in order for a given STEM

    Recent findings in colon cancer cells indicate that inhibition of the mitochondrial H+-adenosine triphosphate (ATP) synthase by the ATPase inhibitory factor 1 (IF1) promotes aerobic glycolysis and a reactive oxygen species (ROS)-mediated signal that enhances proliferation and cell survival. Herein, we have studied the expression, biological relevance, mechanism of regulation and potential clinical impact of IF1 in some prevalent human carcinomas. We show that IF1 is highly overexpressed in most (>90%) of the colon (n=64), lung (n=30), breast (n=129) and ovarian (n=10) carcinomas studied as assessed by different approaches in independent cohorts of cancer patients. The expression of IF1 in the corresponding normal tissues is negligible. By contrast, the endometrium, stomach and kidney show high expression of IF1 in the normal tissue revealing subtle differences by carcinogenesis. The overexpression of IF1 also promotes the activation of aerobic glycolysis and a concurrent ROS signal in mitochondria of the lung, breast and ovarian cancer cells mimicking the activity of oligomycin. IF1-mediated ROS signaling activates cell-type specific adaptive responses aimed at preventing death in these cell lines. Remarkably, regulation of IF1 expression in the colon, lung, breast and ovarian carcinomas is exerted at post-transcriptional levels. We demonstrate that IF1 is a short-lived protein (t1/2 ∼100 min) strongly implicating translation and/or protein stabilization as main drivers of metabolic reprogramming and cell survival in these human cancers. Analysis of tumor expression of IF1 in cohorts of breast and colon cancer patients revealed its relevance as a predictive marker for clinical outcome, emphasizing the high potential of IF1 as therapeutic target.

    Abstract To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) in clinical practice. We performed a multicenter prospective study in Japan of biological disease-modifying antirheumatic drug (bDMARD)-naive RA patients with moderate to high disease activity treated with conventional synthetic DMARDs (csDMARDs) at study entry. We longitudinally observed 408 patients for 1 year and assessed disease activity every 3 months. CRRP was defined as yearly progression of modified total Sharp score (mTSS) > 3.0 U. We also divided the cohort into 2 groups based on disease duration (<3 vs ≥3 years) and performed a subgroup analysis. CRRP was found in 10.3% of the patients. A multiple logistic regression analysis revealed that the independent variables to predict the development of CRRP were: CRP at baseline (0.30 mg/dL increase, 95% confidence interval [CI] 1.01–1.11), time-integrated Disease Activity Score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) during the 1 year postbaseline (12.4-unit increase, 95%CI 1.17–2.59), RA typical erosion at baseline (95%CI 1.56–21.1), and the introduction of bDMARDs (95%CI 0.06–0.38). The subgroup analysis revealed that time-integrated DAS28-ESR is not a predictor whereas the introduction of bDMARDs is a significant protective factor for CRRP in RA patients with disease duration <3 years. We identified factors that could be used to predict the development of CRRP in RA patients treated with DMARDs. These variables appear to be different based on the RA patients’ disease durations.

    The volume of health-related user-created content, especially hospital-related questions and answers in online health communities, has rapidly increased. Patients and caregivers participate in online community activities to share their experiences, exchange information, and ask about recommended or discredited hospitals. However, there is little research on how to identify hospital service quality automatically from the online communities. In the past, in-depth analysis of hospitals has used random sampling surveys. However, such surveys are becoming impractical owing to the rapidly increasing volume of online data and the diverse analysis requirements of related stakeholders. As a solution for utilizing large-scale health-related information, we propose a novel approach to identify hospital service quality factors and overtime trends automatically from online health communities, especially hospital-related questions and answers. We defined social media-based key quality factors for hospitals. In addition, we developed text mining techniques to detect such factors that frequently occur in online health communities. After detecting these factors that represent qualitative aspects of hospitals, we applied a sentiment analysis to recognize the types of recommendations in messages posted within online health communities. Korea's two biggest online portals were used to test the effectiveness of detection of social media-based key quality factors for hospitals. To evaluate the proposed text mining techniques, we performed manual evaluations on the extraction and classification results, such as hospital name, service quality factors, and recommendation types using a random sample of messages (ie, 5.44% (9450/173,748) of the total messages). Service quality factor detection and hospital name extraction achieved average F1 scores of 91% and 78%, respectively.

    The cyanobacteria community dynamics in two eutrophic freshwater bodies (Tiegang Reservoir and Shiyan Reservoir) was studied with both a traditional microscopic counting method and a PCR-DGGE genotyping method. Results showed that cyanobacterium Phormidium tenue was the predominant species; twenty-six cyanobacteria species were identified in water samples collected from the two reservoirs, among which fourteen were identified with the morphological method and sixteen with the PCR-DGGE method. The cyanobacteria community composition analysis showed a seasonal fluctuation from July to December. The cyanobacteria population peaked in August in both reservoirs, with cell abundances of 3.78 × 108 cells L-1 and 1.92 × 108 cells L-1 in the Tiegang and Shiyan reservoirs, respectively. Canonical Correspondence Analysis (CCA) was applied to further investigate the correlation between cyanobacteria community dynamics and environmental factors. The result indicated that the cyanobacteria community dynamics was mostly correlated with pH, temperature and total nitrogen. This study demonstrated that data obtained from PCR-DGGE combined with a traditional morphological method could reflect cyanobacteria community dynamics and its correlation with environmental factors in eutrophic freshwater bodies.

    Benthic accumulations of filamentous, mat-forming bacteria occur throughout the oceans where bisulfide mingles with oxygen or nitrate, providing key but poorly quantified linkages between elemental cycles of carbon, nitrogen and sulfur. Here we used the autonomous underwater vehicle Sentry to conduct a contiguous, 12.5 km photoimaging survey of sea-floor colonies of filamentous bacteria between 80 and 579 m water depth, spanning the continental shelf to the deep suboxic waters of the Santa Barbara Basin (SBB). The survey provided >31 000 images and revealed contiguous, white-colored bacterial colonization coating > ∼80% of the ocean floor and spanning over 1.6 km, between 487 and 523 m water depth. Based on their localization within the stratified waters of the SBB we hypothesize a dynamic and annular biogeochemical zonation by which the bacteria capitalize on periodic flushing events to accumulate and utilize nitrate. Oceanographic time series data bracket the imaging survey and indicate rapid and contemporaneous nitrate loss, while autonomous capture of microbial communities from the benthic boundary layer concurrent with imaging provides possible identities for the responsible bacteria. Based on these observations we explore the ecological context of such mats and their possible importance in the nitrogen cycle of the SBB.

    Queensborough Community College (QCC), a constituent campus of the City University of New York (CUNY), has modified the introductory Meteorology Class lecture and lab to include active learning activities and discovery based learning. The modules were developed at QCC and other 4 year colleges and designed to introduce basic physical concepts important in meteorology. The modules consisted of either interactive lecture demonstrations or discovery-based activities. The discovery based activities are intended to have students become familiar with scientific investigation. Students engage in formulating hypotheses, developing and carrying out experiments, and analyzing scientific data. These activities differ from traditional lab experiments in that they avoid "cookbook" procedures and emphasize having the students learn about physical concepts by applying the scientific method. During the interactive lecture demonstrations the instructor describes an experiment/phenomenon that is to be demonstrated in class. Students discuss the phenomenon based on their experiences and make a prediction about the outcome. The class then runs the experiment, makes observations, and compares the expected results to the actual outcome. As a result of these activities students in the introductory Meteorology class scored higher in exams questions measuring conceptual understanding, as well as factual knowledge. Lower scoring students demonstrated the greatest benefit, while the better students had little (or no) changes. All students also had higher self-efficacy scores after the intervention, compared to an unmodified class.

    This study examined the association of subjective and objective community contextual factors with stigma of mental illness in a sample of users of community mental health services centers in South Korea. Five hundred thirty-two persons with MI were surveyed on perceived stigma and experienced stigma, and on two subjective measures of community characteristics-perceived disorder and perceived collective efficacy of their neighborhood. Objective community indicators at the neighborhood level were collected from a government administrative data base. Multilevel statistical analysis was conducted to identify the effects of individual-level characteristics and community-level objective indicators on stigma. Perceived neighborhood disorder was associated with both perceived stigma and experienced stigma. Perceived collective efficacy was associated with perceived stigma but not experienced stigma. The proportion of persons with disabilities in the neighborhood, an objective community indicator, was associated with experienced stigma. Mental health practitioners and policy planners need to examine the relevance of neighborhood characteristics in the design of policy and practice interventions in order to enhance the social inclusion of persons with MI.

    This study was conducted to identify the driving factors behind fungal community dynamics during agricultural waste composting. Fungal community abundance and structure were determined by quantitative PCR and denaturing gradient gel electrophoresis analysis combined with DNA sequencing. The effects of physico-chemical parameters on fungal community abundance and structure were evaluated by least significant difference tests and redundancy analysis. The results showed that Cladosporium bruhnei, Hanseniaspora uvarum, Scytalidium thermophilum, Tilletiopsis penniseti, and Coprinopsis altramentaria were prominent during the composting process. The greatest variation in the distribution of fungal community structure was statistically explained by pile temperature and total organic carbon (TOC) (P < 0.05). A significant amount of the variation (74.6 %) was explained by these two parameters alone. Fungal community abundance was found to be significantly related to pH, while pH was significantly influenced by pile temperature and nitrate levels (P < 0.05), and these parameters were found to be the most likely to influence or be influenced by the fungal community during composting.

    Fungi provide relevant ecosystem services contributing to primary productivity and the cycling of nutrients in forests. These fungal inputs can be decisive for the resilience of Mediterranean forests under global change scenarios, making necessary an in-deep knowledge about how fungal communities operate in these ecosystems. By using high-throughput sequencing and enzymatic approaches, we studied the fungal communities associated with three genotypic variants of Pinus pinaster trees, in 45-year-old common garden plantations. We aimed to determine the impact of biotic (i.e., tree genotype) and abiotic (i.e., season, site) factors on the fungal community structure, and to explore whether structural shifts triggered functional responses affecting relevant ecosystem processes. Tree genotype and spatial-temporal factors were pivotal structuring fungal communities, mainly by influencing their assemblage and selecting certain fungi. Diversity variations of total fungal community and of that of specific fungal guilds, together with edaphic properties and tree's productivity, explained relevant ecosystem services such as processes involved in carbon turnover and phosphorous mobilization. A mechanistic model integrating relations of these variables and ecosystem functional outcomes is provided. Our results highlight the importance of structural shifts in fungal communities because they may have functional consequences for key ecosystem processes in Mediterranean forests.

    This study measured geographic variation in depression hospitalizations and identified community-level risk factors. Depression hospitalizations were identified from the Statewide Inpatient Database. The dependent variable was specified as the indirectly standardized hospitalization rate. County-level data for 14 states were collected from federal agencies. The Bayesian spatial regression model included socio-demographic, economic, and health system characteristics as independent variables. There were 8.5 depression hospitalizations per 1,000 residents. 8.8% of counties had hospitalization rates 33% greater than the standardized rate. Significant risk factors included unemployment, poverty, physician supply, and hospital bed supply. Significant protective factors included rurality, economic dependence, and housing stress.

    2013-05-01

    The epidemiology of type 2 diabetes in Germany is of major societal interest, as is the question of the predictive value of genetic and acquired risk factors. We present clinically relevant aspects of these topics on the basis of a selective review of pertinent literature retrieved by a PubMed search that centered on population-based studies. The German Health Interview and Examination Survey for Adults (Studie zur Gesundheit Erwachsener in Deutschland [DEGS1], 2008-2011) revealed that diabetes was diagnosed in 7.2% of the population aged 18 to 79 years (women 7.4%, men 7.0%). These figures are two percentage points higher than those found in the preceding national survey (1998). The percentage of cases that were not captured by these surveys is estimated at 2% to 7% depending on the method. Independently of personal factors (the individual's life style), it seems that living in a disadvantaged region characterized by high unemployment, air pollution, and poor infrastructure raises the risk of diabetes. Moreover, type 2 diabetes has a substantial hereditary component. More than 60 genetic regions have been identified to date that affect the risk of type 2 diabetes, yet all of them together account for only 10% to 15% of the genetic background of the disease. The prevalence of type 2 diabetes in Germany has risen in recent years. The discovery of new genetic variants that confer a higher risk of developing the disease has improved our understanding of insulin secretion in diabetes pathogenesis rather than the prediction of individual diabetes risk ("personalized medicine").

    Little evidence exists examining cardiovascular risk factors among Asian Americans and how social determinants such as nativity status and education pattern risk in the United States (U.S.) context. We used the National Health and Nutrition Examination Survey, which purposely oversampled Asian Americans from 2011 to 2014, and examined prevalence of Type II diabetes, smoking and obesity for Asian Americans (n=1363) and non-Latino Whites (n=4121). We classified Asian Americans as U.S. or foreign-born and by years in the U.S. Obesity status was based on standard body mass index (BMI) cut points of ≥30kg/m(2) and Asian-specific cut points (BMI≥25kg/m(2)) that may be more clinically relevant for this population. We fit separate logistic regression models for each outcome using complex survey design methods and tested for the joint effect of race, nativity and education on each outcome. Diabetes and obesity prevalence (applying Asian-specific BMI cut points) were higher among Asian Americans when compared to non-Latino Whites but smoking prevalence was lower. These patterns remained in fully adjusted models and showed small increases with longer duration in the U.S. Joint effects models showed higher odds of prevalent Type II diabetes and obesity (Asian-specific) for foreign-born Asians, regardless of years in the U.S. and slightly higher risk for lowe ducation, when compared to non-Latino Whites with high education. Smoking models showed significant interaction effects between race and education for non-Latino Whites only. Our study supports the premise that social as well as clinical factors should be considered when developing health initiatives for Asian Americans.

    Intravenous delivery of adenoviruses is the optimal route for many gene therapy applications. Once in the blood, coagulation factor X (FX) binds to the adenovirus capsid and protects the virion from natural antibody and classical complement-mediated neutralisation in mice. However, to date, no studies have examined the relevance of this FX/viral immune protective mechanism in human samples. In this study, we assessed the effects of blocking FX on adenovirus type 5 (Ad5) activity in the presence of human serum. FX prevented human IgM binding directly to the virus. In individual human sera samples (n=25), approximately half of those screened inhibited adenovirus transduction only when the Ad5–FX interaction was blocked, demonstrating that FX protected the virus from neutralising components in a large proportion of human sera. In contrast, the remainder of sera tested had no inhibitory effects on Ad5 transduction and FX armament was not required for effective gene transfer. In human sera in which FX had a protective role, Ad5 induced lower levels of complement activation in the presence of FX. We therefore demonstrate for the first time the importance of Ad–FX protection in human samples and highlight subject variability and species-specific differences as key considerations for adenoviral gene therapy.

This systematic review identifies critical cultural contexts central to the literature discussed in health research on Korean Americans. We examined 14 research reports of 801 potentially eligible articles published between 2000 and 2016 and analyzed their contribution to cultural contexts among Korean Americans based on the PEN-3 model. This review highlights how cultural contexts impact health and health behaviors of Korean Americans, and may contribute to health disparities in the United States. The key cultural contexts highlighted in this review include social support/social network, family, gender role expectations, and a holistic view of health and illness. These cultural contexts should be incorporated in designing culturally relevant, effective, and sustainable health interventions for Korean Americans, which will contribute to eliminating health disparities for this ethnic group who experience great obstacles to healthcare access and healthy behaviors.

    Allergic contact dermatitis (ACD) in children is increasing. Sensitization to contact allergens can start in early infancy. The epidermal barrier is crucial for the development of sensitization and elicitation of ACD. Factors that may influence the onset of sensitization in children are atopic dermatitis, skin barrier defects and intense or repetitive contact with allergens. Topical treatment of ACD is associated with cutaneous sensitization, although the prevalence is not high. ACD because of haptens in shoes or shin guards should be considered in cases of persistent foot eruptions or sharply defined dermatitis on the lower legs. Clinical polymorphism of contact dermatitis to clothing may cause difficulties in diagnosing textile dermatitis. Toys are another potentially source of hapten exposure in children, especially from toy-cosmetic products such as perfumes, lipstick and eye shadow. The most frequent contact allergens in children are metals, fragrances, preservatives, neomycin, rubber chemicals and more recently also colourings. It is very important to remember that ACD in young children is not rare, and should always be considered when children with recalcitrant eczema are encountered. Children should be patch-tested with a selection of allergens having the highest proportion of positive, relevant patch test reactions. The allergen exposure pattern differs between age groups and adolescents may also be exposed to occupational allergens. The purpose of this review is to alert the paediatrician and dermatologist of the frequency of ACD in young children and of the importance of performing patch tests in every case of chronic recurrent or therapy-resistant eczema in children.

  11. Automatic relevance determination in nonnegative matrix factorization with the β-divergence.

    2013-07-01

    This paper addresses the estimation of the latent dimensionality in nonnegative matrix factorization (NMF) with the β-divergence. The β-divergence is a family of cost functions that includes the squared euclidean distance, Kullback-Leibler (KL) and Itakura-Saito (IS) divergences as special cases. Learning the model order is important as it is necessary to strike the right balance between data fidelity and overfitting. We propose a Bayesian model based on automatic relevance determination (ARD) in which the columns of the dictionary matrix and the rows of the activation matrix are tied together through a common scale parameter in their prior. A family of majorization-minimization (MM) algorithms is proposed for maximum a posteriori (MAP) estimation. A subset of scale parameters is driven to a small lower bound in the course of inference, with the effect of pruning the corresponding spurious components. We demonstrate the efficacy and robustness of our algorithms by performing extensive experiments on synthetic data, the swimmer dataset, a music decomposition example, and a stock price prediction task.

    We assessed the perceived sustainability of community health programs organized by local intersectoral coalitions, as well as the factors that collaborating partners think might influence sustainability. Semi-structured interviews were conducted among 31 collaborating partners of 5 community health programs in deprived neighborhoods in the southern part of the Netherlands. The interview guide was based on a conceptual framework that includes factors related to the context, the leading organization, leadership, the coalition, collaborating partners, interventions and outcomes. Interviews were recorded, transcribed and content analyzed using NVivo 8.0. Participants in each of the programs varied in their perceptions of the sustainability of the program, but those people collaborating in pre-existing neighborhood structures expressed relatively high faith in their continuation. The participating citizens in particular believed that these structures would continue to address the health of the community in the future. We found factors from all categories of the conceptual framework that were perceived to influence sustainability. The program leaders appeared to be crucial to the programs, as they were frequently mentioned in close interaction with other factors. Program leaders should use a motivating and supportive leadership style and should act as 'program champions'. © The Author (2013). Published by Oxford University Press. All rights reserved.

    2013-12-01

    This paper explores the effect of risk and socioeconomic factors on maternal mortality at the community level in Madagascar using a unique, nationwide panel of communes (i.e., counties). Previous work in this area uses individual or cross-country data to study maternal mortality, however, studying maternal mortality at the community level is imperative because this is the level at which most policy is implemented. The results show that longer travel time from the community to the hospital leads to a high level of maternal mortality. The findings suggest that improvement to transportation systems and access to hospitals with surgery rooms are needed to deal with obstetric complications and reduce maternal mortality.

    The purpose of this exploratory study was to examine personal characteristics, socio-environmental conditions, and motivational factors that potentially influence HIV vaccine research community engagement. Specifically, the study identified predictive aspects that may aid in future community program development on HIV vaccine issues. A cross-sectional survey consisting of evaluative measures, demographics, social interaction, and health information-seeking behaviors was conducted. Participants were a diverse group of 452 adults (>or=18 years) at HIV vaccine awareness-building and community education gatherings in Atlanta. The sample included large numbers of women (n=251) and minorities (n=224). In multivariate analysis, the overall logistic regression model was significant, with a resulting coefficient of determination (Nagelkerke R(2)) of .505. Highly significant factors included an excellent activity/event rating (log odds beta = 4.521, P< .001), White race (beta= -.835, P= .005), greater educational attainment (beta= .725, P= .011), travel distance (beta = 1.186, P= .002), and excellent perception of the study site (beta=2.131, P< .001). Subgroup analyses by gender and race revealed similar findings. These data demonstrate the importance of building a favorable study site image and gaining familiarity in the community to aid in the promotion of HIV vaccine research on an ongoing basis.

    There is evidence of considerable variability in the quality of residential services and a tendency for residents' quality of life to co-vary with ability level. Quality of life of 154 people living in 47 small community residences was assessed using 14 subjective and objective indicators. Information on setting structure, processes, and staff working methods was collected. Factors associated with resident choice, activity, and social and community well-being were modeled using multivariate regression, which controlled for the confounding effect of ability level. Few factors associated with subjective quality of life were found. Resident ability and staff attention to residents had a strong effect across objective measures. Number of residents and staff had little explanatory power. Staff working methods had an inconsistent impact.

  19. What factors are driving increasing demand for community nursing?

    Demand for district nursing services is increasing significantly. With increasing economic pressures, services are struggling to meet increases in demand, and are looking to become more proactive in planning for future demand. Traditional quantitative forecasting methods have limited use, because of the complexity of inter-linking factors that potentially drive demand for community services. Qualitative system dynamics approaches can be useful to model the complex interplay of causal factors leading to an effect, such as increased demand for services, and identify particular areas of concern for future focus. We ran a facilitated qualitative system dynamics workshop with representatives working across community nursing services in Cornwall. The generated models identified 7 key areas of concern that could be significantly contributing to demand for district nursing services. We outline the identified problem areas in this paper, and discuss potential recommendations to reduce their effects based on causal links identified in the models.

    Demoralisation is a psychological state occurring in stressful life situations where a person feels unable to respond effectively to their circumstances, characterised by feelings of distress, subjective incompetence, helplessness and hopelessness. The period after the birth of a first baby is a time of great changes and disruptions to many aspects of the mother's physical, psychological and social functioning. This can lead to feelings of distress, a sense of incompetence and helplessness. This study aimed to examine: (1) the psychometric properties of the Demoralisation Scale in a community setting; (2) the prevalence of demoralisation symptoms among primiparous women in the community; and (3) factors that are uniquely associated with demoralisation in the early postnatal period. Primiparous women attending community maternal health centres (n = 400) were recruited and administered the study's questionnaires through a telephone interview. The Demoralisation Scale was found to be a reliable and valid tool among women in the community who had recently given birth. Higher levels of demoralisation were independently associated with lower confidence on going home from the hospital after birth, lower rating of mother's self-rated global health, more than 3 h of infant crying and fussing in the last 24 h, and a controlling partner, after symptoms of depression and anxiety, and vulnerable personality characteristics were controlled for. The relevance of demoralisation to postnatal health practitioners in the community is in helping them to better understand women's experiences and to intervene in a way that is more meaningful and less stigmatising to women.

  1. Plant available silicon in South-east Asian rice paddy soils - relevance of agricultural practice and of abiotic factors

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Background Silicon (Si) plays a crucial role in rice production. Si content of rice plants exceeds the content of other major nutrients such as nitrogen, phosphorous or potassium. Recent studies showed that in some environments external supply of Si can enhance the growth of rice plants. Rice plants express specific Si transporters to absorb Si from soil solutions in form of silicic acid, which precipitates in tissue cells forming amorphous silica bodies, called phytoliths. The phytoliths are returned to soils with plant residues. They might be a main source of plant available silicic acid in soils. Aims In this study we assess the effects of rice paddy cultivation on the stocks of `reactive` Si fractions in mineral topsoils of rice paddy fields in contrasting landscapes. The `reactive` Si fractions are presumed to determine the release of plant-available silicic acid in soils. We consider the relevance of abiotic factors (mineral assemblage; soil weathering status) and agricultural practice for these fractions. Agricultural practices, which were assumed to affect the stocks of `reactive` Si were (i) the usage of different rice varieties (which might differ in Si demand), (ii) straw residue management (i.e., whether straw residues are returned to the fields or removed and used e.g. as fodder), and (iii) yield level and number of crops per year. Material and methods Soils (top horizon of about 0-20 cm depth) were sampled from rice paddy fields in 2 mountainous and 5 lowland landscapes of contrasting geologic conditions in Vietnam and the Philippines. Ten paddy fields were sampled per landscape. The rice paddy management within landscapes differed when different farmers and/or communities managed the fields. We analysed the following fractions of `reactive` Si in the soils: acetate-extractable Si (dissolved and easily exchangeable Si), phosphate-extractable Si (adsorbed Si), oxalate extractable Si (Si associated with poorly-ordered sesquioxides), NaOH extractable Si

    Oral nutritional supplements (ONS) are a recommended form of nutritional intervention for older malnourished persons when a 'food first' approach and/or food fortification prove ineffective. The efficacy of ONS will depend on, amongst other factors, whether persons do, or do not, consume their prescribed amount. Factors influencing ONS consumption can be product, context, or person related. Whereas product and context have received some attention, little is known about the person factors driving ONS consumption. In addition, the relative importance of the product, context, and person factors to ONS consumption is not known. Using the means-end chain (MEC) method, the current study elucidated personally relevant factors (product, context, and person factors) related to ONS consumption in two groups of older nutritionally frail ONS users: community-dwelling persons and care home residents with mainly somatic disorders. To our knowledge, the current work is the first to apply the MEC method to study older nutritionally frail ONS users. Forty ONS users (n = 20 per group) were recruited via healthcare professionals. The level of frailty was assessed using the FRAIL scale. Both groups were interviewed for 30 to 45 minutes using the soft laddering technique. The laddering data were analysed using LadderUX software™. The MEC method appeared to work well in both groups. The majority of the participants took ONS on their doctor's or dietician's prescription as they trusted their advice. The community-dwelling group took ONS to prolong their independence, whereas the care home group reported values that related more to small improvements in quality of life. In addition, care home residents perceived themselves as dependent on their caregiver for their ONS arrangements, whereas this dependence was not reported by community-dwelling persons. Key insights from this work will enable doctors and dieticians to customize their nutritional interventions to ONS users' personal

    Objective: To investigate the prognostic factors relevant to acute low-tone sensorineural hearing loss (ALHL). Methods: 196 adult ALHL patients, including 82 males and 114 females with mean age of (43.1±14.3)years old were included. All patients received the same therapy and were evaluated the curative effect. To evaluate the impact factors on the prognosis of hearing, inclusive of age, gender, time delay before the first visit, degree of deafness, vestibular function, electrocochleogram, and the serum levels of thyroxines by SPSS 18.0 software. Results: Of those 196 patients with ALHL, 124(63.3%) were recovery, 5(2.6%) were excellent better, 42(21.4%) were better, and 25 (12.8%) were poor, with a total effective rate of 87.2%. Among 15 (12.1%) who recurred the hearing loss, 2 developed into Meniere's disease during the follow-up. The mean age of patients with poor hearing effect was significantly older than that of other patients (P<0.05). No relativity was found between gender and hearing curative effect. There existed a statistical difference in total effective rate among subjects with different histories (P<0.05). In addition, the recovery rate was significantly different between groups, i. e., the course of disease was less than 14 days, between 14 days and 6 months, and between 6 months and 2 years (P<0.05). There was no statistical significance in total effective rate among different degrees of deafness (P>0.05). However, in term of the recovery rate, the difference was statistical significance (P<0.05). The recovery rate in patients with mild hearing loss was higher than that in middle or heavy hearing loss (both P<0.05). Among patients with mild deafness, the recovery rate in patients whose history was less than 3 months was significantly higher than that more than 3 months (P<0.05). For moderate deafness patients, the recovery rate in patients whose history was less than 7 days was significantly higher than that more than 1 month (P<0.05). There were

    The mechanisms shaping island biotas are not yet well understood mostly because of a lack of studies comparing eco-evolutionary fingerprints over entire taxonomic groups. Here, we linked community structure (richness, frequency and nestedness) and genetic differentiation (based on mitochondrial DNA) in order to compare insular butterfly communities occurring over a key intercontinental area in the Mediterranean (Italy-Sicily-Maghreb). We found that community characteristics and genetic structure were influenced by a combination of contemporary and historical factors, and among the latter, connection during the Pleistocene had an important impact. We showed that species can be divided into two groups with radically different properties: widespread taxa had high dispersal capacity, a nested pattern of occurrence, and displayed little genetic structure, while rare species were mainly characterized by low dispersal, high turnover and genetically differentiated populations. These results offer an unprecedented view of the distinctive butterfly communities and of the main processes determining them on each studied island and highlight the importance of assessing the phylogeographic value of populations for conservation.

    Background Despite substantial investments made over the past 40 years in low income countries, governments cannot be viewed as the principal health care provider in many countries. Evidence on the role of the private sector in the delivery of health services is becoming increasingly available. In this study, we set out to determine the extent to which the private sector has been utilized in providing integrated care for sick children under 5 years of age with community–acquired malaria, pneumonia or diarrhoea. Methods We reviewed the published literature for integrated community case management (iCCM) related experiences within both the public and private sector. We searched PubMed and Google/Google Scholar for all relevant literature until July 2014. The search terms used were “malaria”, “pneumonia”, “diarrhoea”, “private sector” and “community case management”. Results A total of 383 articles referred to malaria, pneumonia or diarrhoea in the private sector. The large majority of these studies (290) were only malaria related. Most of the iCCM–related studies evaluated introduction of only malaria drugs and/or diagnostics into the private sector. Only one study evaluated the introduction of drugs and diagnostics for malaria, pneumonia and diarrhoea in the private sector. In contrast, most iCCM–related studies in the public sector directly reported on community case management of 2 or more of the illnesses. Conclusions While the private sector is an important source of care for children in low income countries, little has been done to harness the potential of this sector in improving access to care for non–malaria–associated fever in children within the community. It would be logical for iCCM programs to expand their activities to include the private sector to achieve higher population coverage. An implementation research agenda for private sector integrated care of febrile childhood illness needs to be developed and implemented in

  7. Maternal, neonatal and community factors influencing neonatal mortality in Brazil.

    Child mortality (the mortality of children less than five years old) declined considerably in the developing world in the 1990s, but infant mortality declined less. The reductions in neonatal mortality were not impressive and, as a consequence, there is an increasing percentage of infant deaths in the neonatal period. Any further reduction in child mortality, therefore, requires an understanding of the determinants of neonatal mortality. 209,628 birth and 2581 neonatal death records for the 1998 birth cohort from the city of São Paulo, Brazil, were probabilistically matched. Data were from SINASC and SIM, Information Systems on Live Births and Deaths of Brazil. Logistic regression was used to find the association between neonatal mortality and the following risk factors: birth weight, gestational age, Apgar scores at 1 and 5 minutes, delivery mode, plurality, sex, maternal education, maternal age, number of prior losses, prenatal care, race, parity and community development. Infants of older mothers were less likely to die in the neonatal period. Caesarean delivery was not found to be associated with neonatal mortality. Low birth weight, pre-term birth and low Apgar scores were associated with neonatal death. Having a mother who lives in the highest developed community decreased the odds of neonatal death, suggesting that factors not measured in this study are behind such association. This result may also indicate that other factors over and above biological and more proximate factors could affect neonatal death.

    BACKGROUND: In most cases, autism spectrum disorders (ASD) can be reliably diagnosed at two to three years of age. However, Canadian data reveal a median age at diagnosis of approximately four years. OBJECTIVE: To examine general paediatricians’ practices regarding ASD screening and identify factors that influence decisions regarding the use of ASD screening tools. METHODS: Using a qualitative inquiry-based interpretive description approach, 12 paediatricians from four practice groups participated in four focus groups and one individual interview. These were conducted using semistructured interviews, digitally recorded and transcribed verbatim. RESULTS: Five main domains of themes were identified related to screening tool use: benefits; needs not addressed; elements that limit utility; elements that encourage utility; and implementation challenges. Factors influencing practice included availability of time, comfort with screening tool use, previous use and knowledge about specific tools. Systemic factors included knowledge and access to community resources, as well as the ability to provide support to the child and family. CONCLUSION: The results from the present study identified important factors that influence paediatric practice in ASD screening. As screening tools improve, it will be important to examine the implementation and effectiveness of screening tools and strategies for increased uptake. Future research will also need to attend to the practical needs of physicians and communities in the aim of earlier diagnosis and rapid access to interventional resources. PMID:26175565

    Background Maternal mortality and morbidity reflect the status of population health and quality of life across nations. Poor understanding of the interplay of many antecedent factors, including sociocultural, economic and logistic factors, combined with an overwhelming poor health services delivery, is a basic challenge in several countries, particularly in rural settings where functional health care services are relatively scarce. There are still uncertainties as to the extent of this burden, owing to current challenges with information and data collation. This study aimed at identifying nonmedical factors associated with maternal mortality in rural and semiurban communities of southwestern Nigeria. Methodology The study was carried out in Ado-Odo/Ota Local Government Area of Ogun State. A multistage sampling technique and an informant survey approach were used in the study. A total sample of 360 eligible respondents were selected randomly from 11 out of 16 political wards in the study area and interviewed through the administration of questionnaires. The data were processed using descriptive statistics and regression analyses. Results Place of consultation (P=0.000), who pays the treatment costs (P=0.000), awareness of pregnancy complications (P=0.002) and knowledge of the place of antenatal care treatment (P=0.000) significantly influenced maternal mortality (proxy by place of delivery of last birth). The F-statistic (15.100) confirmed the hypothesis that nonmedical factors influence maternal mortality. The correlation of predictor variables was significant at both the 0.01 level and the 0.05 level (2-tailed). Conclusion Our findings suggest that in a rural community setting with a depleted health care system, health education tailored toward community culture, subsidized maternal health care services by the government and operators of private clinics, as well as empowering and improving the status of women may reduce maternal mortality and prompt better

    We explored with Aboriginal adults living in a remote Australian community the social context of food choice and factors perceived to shape food choice. An ethnographic approach of prolonged community engagement over 3 years was augmented by interviews. Our findings revealed that knowledge, health, and resources supporting food choice were considered "out of balance," and this imbalance was seen to manifest in a Western-imposed diet lacking variety and overrelying on familiar staples. Participants felt ill-equipped to emulate the traditional pattern of knowledge transfer through passing food-related wisdom to younger generations. The traditional food system was considered key to providing the framework for learning about the contemporary food environment. Practitioners seeking to improve diet and health outcomes for this population should attend to past and present contexts of food in nutrition education, support the educative role of caregivers, address the high cost of food, and support access to traditional foods.

    Objective The aim of the present study was to investigate the effects of work organisation on the emotional labour withdrawal behaviour of Australian community nurses.Methods Using a paper-based survey, a sample of 312 Australian community nurses reported on their emotional dissonance, withdrawal behaviours (i.e. job neglect, job dissatisfaction, stress-related presenteeism) and work organisation. A model to determine the partial mediation effect of work organisation was developed based on a literature review. The fit of the proposed model was assessed via structural equation modelling using Analysis of Moment Structures (AMOS; IMB).Results Community nurses with higher levels of emotional dissonance were less likely to be satisfied with their job and work organisation and had a higher tendency to exhibit withdrawal behaviours. Work organisational factors mediated this relationship.Conclusion Emotional dissonance can be a potential stressor for community nurses that can trigger withdrawal behaviours. Improving work organisational factors may help reduce emotional conflict and its effect on withdrawal behaviours.What is known about the topic? Although emotional labour has been broadly investigated in the literature, very few studies have addressed the effect of the quality of work organisation on nurses' withdrawal behaviours in a nursing setting.What does this paper add? This paper provides evidence that work organisation affects levels of emotional dissonance and has an effect on job neglect through stress-related presenteeism.What are the implications for practitioners? In order to minimise stress-related presenteeism and job neglect, healthcare organisations need to establish a positive working environment, designed to improve the quality of relationships with management, provide appropriate rewards, recognition and effective workload management and support high-quality relationships with colleagues.

    The goal of stroke rehabilitation has shifted from mere survival of a victim to how well a survivor can be effectively reintegrated back into the community. The present study determined the level of satisfaction with community reintegration (CR) and related factors among Nigerian community-dwelling stroke survivors (CDSS). This was a cross-sectional survey of 71 volunteering CDSS (35 males, 36 females) from selected South-Eastern Nigerian communities. Reintegration to Normal Living Index was used to assess participants' CR. Data was analysed using Spearman rank-order correlation, Kruskal-Wallis and Mann-Whitney U tests at p≤0.05. Participants generally had deficits in CR which was either mild/moderate (52.1%) or severe (47.9%). Scores in the CR domains of distance mobility, performance of daily activities, recreational activities and family roles were particularly low (median scores ≤ 4). CR was significantly correlated with and influenced by age (r=-0.35; p=0.00) and presence/absence of diabetes mellitus (u=3.56.50; p=0.01), pre- (k=6.13; p=0.05) and post-stroke employment (k=18.26; p=0.00) status, type of assistive mobility device being used (AMD) (k=25.39; p=0.00) and support from the community (k=7.15; p=0.03) respectively. CR was generally poor for this CDSS sample. Survivors who are older, having diabetes as co-morbidity, using AMD (particularly wheel-chair) and without employment pre- and/or post-stroke may require keener attention. Rehabilitation focus may be targeted at enhancing mobility functions, vocational and social skills.

    Distinguishing between effects of natural and anthropogenic environmental factors on ecosystems is a fundamental problem in environmental science. In river systems the longitudinal gradient of environmental factors is one of the most relevant sources of dissimilarity between communities that could be confounded with anthropogenic disturbances. To test the hypothesis that in macroinvertebrate communities the distribution of species' sensitivity to organic toxicants is independent of natural longitudinal factors, but depends on contamination with organic toxicants, we analysed the relationship between community sensitivity SPEAR(organic) (average community sensitivity to organic toxicants) and natural and anthropogenic environmental factors in a large-scale river system, from alpine streams to a lowland river. The results show that SPEAR(organic) is largely independent of natural longitudinal factors, but strongly dependent on contamination with organic toxicants (petrochemicals and synthetic surfactants). Usage of SPEAR(organic) as a stressor-specific longitude-independent measure will facilitate detection of community disturbance by organic toxicants.

    With their distinct cultural heritage and rural boundaries, American Indian reservation communities offer a unique opportunity to explore protective factors that help buffer adolescents from potential risk behaviors such as violence. Prior published research on Indian communities has not explored three potential protective factors for violence-parental monitoring of adolescents and friends, adolescents' self-efficacy to avoid fighting, and adolescents' interest in learning more about their traditional culture. This paper explores the relationship between these factors and reduced risk of reported violence. In 1998, 630 American Indian students in grades 6-12 were surveyed in five Midwestern, rural Indian reservation schools. Path analysis was used to identify the direct and indirect association of the three potential protective factors with reduced violence behavior. There were significant gender differences both in perceived parental monitoring and in adolescents' self-efficacy. For female adolescents, parental monitoring had the strongest inverse relationship with female adolescents' involvement in violence. Female adolescents' self-efficacy and their interest in learning more about their culture were also inversely associated with violence and therefore potentially important protectors. Male adolescents who reported more interest in learning the tribe's culture had better self-efficacy to avoid violence. However, self-efficacy did not successfully predict their reported involvement in peer violence. These findings support exploring gender differences, parental monitoring, self-efficacy training as well as cultural elements in future violence intervention studies. Further investigation is needed to identify protective factors for risk behaviors among male adolescents and test the generalizability to non-reservation based adolescents.

    Interpersonal violence is a major contributor to the burden of disease globally, and in South Africa, it is the leading cause of injury. There is an emerging consensus that the development of actionable policy and effective prevention strategies for interpersonal violence requires an understanding of the contextual matters that elevate risk for interpersonal violence. The objective of this study was to explore community perceptions of risks for interpersonal violence in five townships in Cape Town, South Africa, with high rates of violence. Focus group discussions were conducted with community members to identify key factors in that contributed to being either a perpetrator or victim of interpersonal violence. The ecological framework was used to classify the risk factors as occurring at individual, relationship, community or society levels. Some of the risk factors identified included alcohol abuse, poverty, informality of settlements and cultural norms. Differences in how each of these risk factors are expressed and experienced in the five communities are also elucidated. This approach enabled the collection of contextual community-based data that can complement conventional surveillance data in the development of relevant community-level strategies for interpersonal violence prevention.

    Adult community-acquired pneumonia (CAP) is a relevant worldwide cause of morbidity and mortality, however the aetiology often remains uncertain and the therapy is empirical. We applied conventional and molecular diagnostics to identify viruses and atypical bacteria associated with CAP in Chile. We used sputum and blood cultures, IgG/IgM serology and molecular diagnostic techniques (PCR, reverse transcriptase PCR) for detection of classical and atypical bacteria (Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumoniae) and respiratory viruses (adenovirus, respiratory syncytial virus (RSV), human metapneumovirus, influenza virus, parainfluenzavirus, rhinovirus, coronavirus) in adults >18 years old presenting with CAP in Santiago from February 2005 to September 2007. Severity was qualified at admission by Fine's pneumonia severity index. Overall detection in 356 enrolled adults were 92 (26%) cases of a single bacterial pathogen, 80 (22%) cases of a single viral pathogen, 60 (17%) cases with mixed bacterial and viral infection and 124 (35%) cases with no identified pathogen. Streptococcus pneumoniae and RSV were the most common bacterial and viral pathogens identified. Infectious agent detection by PCR provided greater sensitivity than conventional techniques. To our surprise, no relationship was observed between clinical severity and sole or coinfections. The use of molecular diagnostics expanded the detection of viruses and atypical bacteria in adults with CAP, as unique or coinfections. Clinical severity and outcome were independent of the aetiological agents detected.

    To determine whether there are differences between the prognostic factors associated with 30-days mortality in patients 65-84 year-old and patients over 84 years hospitalized for community-acquired pneumonia (CAP). An observational study with retrospective data collection was carried out in a representative sample of all CAP in-patients of 27 general hospitals. Data regarding comorbidities, signs and symptoms on admission, radiological and laboratory examinations, and complications during hospitalization were recorded. 1,191 CAP patients were studied, 80.1% in the 65-84 age group and 19.9% in the over 84 age group. Mortality during the first 30 days was 11.9% in the younger group and 20.7% in the older (p < 0.001). In the younger group, the multivariate analysis showed the following independent prognostic factors: general discomfort (odds ratio [OR] = 3.93), respiratory rate > 30/min (OR = 5.02), atrial fibrillation (OR = 3.57), dementia (OR = 9.18), and hospitalization during the previous year (OR = 3.74). In the older group, independent prognostic factors were cancer (OR = 8.4) and renal failure (3.32). Age significantly modified the effect of altered mental state, tachypnea, tachycardia, hyperglycemia, and dementia on mortality. In people over 84 years, except cancer and renal failure, classic CAP prognostic factors used in severity indexes do not distinguish those who will die from those who will not. Therefore, these factors must be interpreted with caution.

    Hepatitis C virus (HCV) is the most common chronic blood-borne infection in the worldwide. This infection is often insidious and one-half of infected patients are asymptomatic. Determination of risk factors for HCV transmission is very important. The aim of this study was to assess the risk factors, transmission to spouses and children for HCV infection in Turkish population. One hundred and fifty-one patients with chronic hepatitis C and 151 control cases were investigated for the probable risk factors of HCV infection. Complete blood count, ALT, AST, albumin, prothrombin time, upper abdomen ultrasonography assessment and percutaneous liver biopsy (not for cirrhotics) were performed in all patients with chronic hepatitis C. Anti-HCV testing was done by using second-generation ELISA in 302 cases. Minor surgical operation (p < 0.001), major surgical operation (p = 0.001), blood transfusion (p < 0.001), multi-partner sex (p < 0.05), frequent dental therapy (p < 0.05), and dental extraction (p < 0.001) in patients with a chronic HCV infection were found to be higher than the control group. No significant difference was found in other risk factors. The rate of hepatitis C virus in index cases was found to be 1.8% in their spouses and 1.2% in their children. Our study showed that surgical operation, frequent dental therapy, dental extraction, multi-partner sex, and blood transmission are the main risk factors for HCV infection in Turkish community.

    Dispersal limitation and environmental conditions are crucial drivers of plant species distribution and establishment. As these factors operate at different spatial scales, we asked: Do the environmental factors known to determine community assembly at broad scales operate at fine scales (few meters)? How much do these factors account for community variation at fine scales? In which way do biotic and abiotic interactions drive changes in species composition? We surveyed the plant community within a dry grassland along a very steep gradient of soil characteristics like pH and nutrients. We used a spatially explicit sampling design, based on three replicated macroplots of 15 × 15, 12 × 12 and 12 × 12 m in extent. Soil samples were taken to quantify several soil properties (carbon, nitrogen, plant available phosphorus, pH, water content and dehydrogenase activity as a proxy for overall microbial activity). We performed variance partitioning to assess the effect of these variables on plant composition and statistically controlled for spatial autocorrelation via eigenvector mapping. We also applied null model analysis to test for non-random patterns in species co-occurrence using randomization schemes that account for patterns expected under species interactions. At a fine spatial scale, environmental factors explained 18% of variation when controlling for spatial autocorrelation in the distribution of plant species, whereas purely spatial processes accounted for 14% variation. Null model analysis showed that species spatially segregated in a non-random way and these spatial patterns could be due to a combination of environmental filtering and biotic interactions. Our grassland study suggests that environmental factors found to be directly relevant in broad scale studies are present also at small scales, but are supplemented by spatial processes and more direct interactions like competition.

    While the development and possibilities of technology today are commonly regarded to be unlimited, knowledge regarding the technological needs of people with mental retardation is fairly limited. The aim of this study was to enhance knowledge of perceived relevance and difficulty in using everyday technology (ET) such as stoves, cell phones, and elevators in adults with mental retardation. 120 participants with different levels of mental retardation were interviewed with the Everyday Technology Use Questionnaire (ETUQ) about their use of such technologies in their everyday life. Analyses of variance, post hoc tests, and regression analyses were used to explore the data. Participants with moderate and severe mental retardation differed in mean perceived difficulty from those with mild mental retardation, suggesting that increased perceived difficulty in ET use is related to the level of mental retardation. Differences between groups were also found in the proportion of items that were relevant for each person. The variables Level of Mental Retardation, Additional Disabilities, and Proportional Relevance of ET Items could together predict 67.2% of the variation in perceived difficulty in technology use. The findings also indicate that age, housing, gender, and geographical district do not covariate with perceived difficulty in ET use.

    Stabilization of growth factors in a wound environment is critical to the wound healing process. Here we report on the stabilization of key growth factors by a unique plant cell wall biomaterial. MicroSheets are clear cell wall fragments isolated from the non-living water storage cells in the pulp or inner gel of Aloe vera L., which has widely been used for wound healing. It was found that MicroSheets bind to a subset of heparin binding growth factors including basic fibroblast growth factor (bFGF) and keratinocyte growth factor (KGF), two key growth factors in the wound healing process. The binding of bFGF and KGF to MicroSheets was inhibited by heparin and also by a pectic substance isolated from the MicroSheets, indicating that the binding was mediated by this pectic component of the MicroSheet. The binding protected the growth factors against protease digestion. Furthermore, the protective effect was also demonstrated with KGF against digestion by wound fluids and by measuring the biological activity. Thus, these results showed that MicroSheets can stabilize certain critical growth factors in wounds and thereby promote the healing process. Incorporation of a material like MicroSheets provides an important functional element in wound dressings, i. e., growth factor stabilization.

    Smoking, a self-selected behavior, is the sixth leading cause of death worldwide. Factors related to smoking in Taiwan's indigenous Malayo-Polynesian population should be elicited and addressed. This study examined the relationship between smoking behavior and individual and family/community factors in indigenous Taiwanese. This study was a secondary analysis of data obtained from household visits in central Taiwan that included a population of 562 indigenous adults aged 20-50 years. Data were analyzed using the chi-square test and hierarchical logistic regression to determine individual and family/community relevant factors of smoking behaviors. The smoking rate in the population studied was 57.48% (39.15% men, 18.33% women). The odds ratio for smoking was markedly higher in men than in women. Smokers were 0.45 times more likely to have fixed sexual partners. The OR for smoking was 2.68 times in households with smokers and 7.03 times in people living in mountainous areas. The issue of smoking in indigenous Taiwanese deserves further attention and concern. Further interventions for the harmful effects of tobacco can focus on younger indigenous people living in mountain regions and on smokers' sexual partners. In addition, male adults, female adults, and heads of households should take a greater role in changing the smoking behaviors of smokers and their family members.

    Personal contextual factors play an essential part in the model of the International Classification of Functioning, Disability and Health (ICF). The WHO has not yet classified personal factors for global use although they impact on the functioning of persons positively or negatively. In 2010, the ICF working group of the German Society of Social Medicine and Prevention (DGSMP) presented a proposal for the classification of personal factors into 72 categories previously arranged in 6 chapters. Now a positioning paper has been added in order to stimulate a discussion about the fourth component of the ICF, to contribute towards a broader and common understanding about the nature of personal factors and to incite a dialogue among all those involved in health care as well as those people with or with-out health problems in order to gain a comprehensive perspective about a person's condition.

    Incidence of breast cancer is on the rise in developed as well as in developing countries. In India it has superseded cervical cancer as the commonest malignancy in women in urban areas. A lot of risk factors have been proposed from time to time that play a causative role in the natural course of this disease. However, they are based on data accumulated from studies conducted mostly in developed countries. Aim of this study was to find out whether these known and/or presumptive breast cancer risk factors hold true for women of developing countries like India also. From 2008 to 2012; 1,463 breast cancer patients were compared side by side with 1,440 matched controls by predetermined questionnaire and anthropometric variables. Data were analyzed by Statistical Package for Social Sciences (SPSS) V19 software todetermine whether selected risk factors were more common in the patient group than the control group. The risk factors under study were also found to be statistically significant for the study populationexcept duration of breastfeeding and family history of breast and ovarian cancers. Risk factors for breast cancer do not differ significantly between developed and developing countries. Hence appropriate time has come for developing countries to incorporate breast cancer risk factors in health education and to consider pharmacological interventions in high risk women.

    Epigenetics is emerging as an attractive mechanism to explain the persistent genomic embedding of early-life experiences. Tightly linked to chromatin, which packages DNA into chromosomes, epigenetic marks primarily serve to regulate the activity of genes. DNA methylation is the most accessible and characterized component of the many chromatin marks that constitute the epigenome, making it an ideal target for epigenetic studies in human populations. Here, using peripheral blood mononuclear cells collected from a community-based cohort stratified for early-life socioeconomic status, we measured DNA methylation in the promoter regions of more than 14,000 human genes. Using this approach, we broadly assessed and characterized epigenetic variation, identified some of the factors that sculpt the epigenome, and determined its functional relation to gene expression. We found that the leukocyte composition of peripheral blood covaried with patterns of DNA methylation at many sites, as did demographic factors, such as sex, age, and ethnicity. Furthermore, psychosocial factors, such as perceived stress, and cortisol output were associated with DNA methylation, as was early-life socioeconomic status. Interestingly, we determined that DNA methylation was strongly correlated to the ex vivo inflammatory response of peripheral blood mononuclear cells to stimulation with microbial products that engage Toll-like receptors. In contrast, our work found limited effects of DNA methylation marks on the expression of associated genes across individuals, suggesting a more complex relationship than anticipated. PMID:23045638

The study population included 600 residents selected from four communities using the method of stratified multistage cluster random sampling. The data on beverage consumption were collected through a questionnaire survey, and analyzed through SPSS, including statistic description and Logistic regression. The average water consumption of four age groups was 889 - 1450 ml. Excluding drinking water, the overall milk consumption was highest, reaching to 1372 ml per week. Apart from those, the highest consumption beverages of preschool children, children and youth, and adults were juice, carbonated beverage, and tea, respectively. Age and food preference were important factors affecting beverage consumption, other influencing factors including gender, BMI and income. The health consciousness on beverage consumption need to be further improved, and intervention measures could be carried out through changing food preference behavior, controlling weight and so on according to different age person, thus beverage consumption will be correctly conducted.

    Fear of crime has been well studied; however, there has yet not been widespread consideration of the potential impact of both individual- and neighborhood-level factors on residents' level of fear of crime. From a logistic-regression analytical standpoint, the present study empirically explores the contribution of several factors in explaining residents' propensity for being fearful of crime. Precisely, the study tests the applicability and generalizability of three theoretical perspectives of fear of crime in the Ghanaian context and examines the effects of residents' attitudes toward the police on their levels of fear of crime. Using large-scale cross-sectional data collected on more than 1,000 residents from 25 neighborhoods in Ghana, the results demonstrate significant predictive effects of both individual- and neighborhood-level factors on citizens' rate of fearfulness. Findings from this study have both theoretical and practical implications, and provide important insights for the police to reduce levels of fear of crime in the community. © The Author(s) 2016.

    Objectives: To identify risk factors for hamstring injury at the community level of Australian football. Methods: A total of 126 community level Australian football players participated in this prospective cohort study. To provide baseline measurements, they completed a questionnaire and had a musculoskeletal screen during the 2000 preseason. All were monitored over the season. Injury surveillance and exposure data were collected for the full season. Survival analysis was used to identify independent predictors of hamstring injury. Results: A hamstring injury was the first injury of the season in 20 players (16%). After adjustment for exposure, increasing age and decreased quadriceps flexibility were identified as significant independent predictors of the time to sustaining a hamstring injury. Older age (⩾23 years) was associated with an increased risk of hamstring injury (RR 3.8; 95% confidence interval (CI) 1.1 to 14.0; p = 0.044). Players with increased quadriceps flexibility (as measured by the modified Thomas test) were less likely to sustain a hamstring injury (RR 0.3; 95% CI 0.1 to 0.8; p = 0.022). Conclusions: The findings of this study can be used in the development of hamstring injury prevention strategies and to identify Australian football players at increased risk of hamstring injury.

    Blood pressure (BP) and associated factors were determined in 1737 men in a remote Kenyan agricultural community. Systolic BP showed no significant rise with age until after 54 years; diastolic BP showed a small rise with age. Both systolic and diastolic BP correlated with weight independent of age. Systolic and diastolic BP correlated positively with casual urinary sodium/potassium and negatively with potassium/creatinine ratios. Both systolic and diastolic BP correlated significantly with the number of years of education, as did urinary sodium/potassium and sodium/creatinine ratios. Potassium/creatinine ratios were negatively correlated with the number of years of education. Blood pressure and urinary sodium/creatinine ratios were significantly lower in subsistence farmers compared with those in other occupations, and potassium/creatinine ratios were significantly higher. Two pilot studies of Luo tribesmen showed a strong correlation between casual urinary electrolyte ratios and those derived from 24-hour urine samples and a greater variance of sodium excretion between these people than that found within individuals. These results suggest that a relationship between BP and casual urine electrolyte estimations may be identifiable in communities where there is less day-to-day dietary variation. They also suggest that some of the changes in BP associated with urbanization could be mediated by changes in dietary electrolytes.

    The policy uses of some of the concepts and models found in diffusion of innovation literatures other than those of economics and marketing were reviewed and evaluated. The results of this review were applied to the specific case of a Solar Total Energy System (STES). The research effort had three parts. The first part was to identify and obtain an overview of the noneconomics social science literature relevant to the problem of forecasting and accelerating adoption rates. After the first part was completed and the principal research perspectives and researchers in the field were identified, a workshop of experts was organized to address the problem of predicting and accelerating diffusion rates for STESs. Finally, the results of the literature review and the workshop are summarized, and a number of approaches suggested by the diffusion literature are used to obtain an evaluation of the adoption potential of STES.

    This study examined the impact of pharmacists' perceptions of errors in dispensing, errors in communication, delays in prescription processing, efficiency and physical mobility in the pharmacy by practice setting and sociotechnical factors (i.e. pharmacy design, drive through pick-up window services and automated dispensing systems). Community pharmacy practice in the USA. A two-page survey was mailed to a geographically stratified random sample of 1047 community pharmacies. One-way analysis of variance was used to determine the impact of attitudinal items with respect to pharmacy practice setting (e.g. mass merchant, supermarket, chain and independent) and sociotechnical factors. Pharmacy characteristics, pharmacist experience and total dispensing errors were also addressed. The response rate was 45.0% (n = 429). Pharmacists perceived that pharmacy design significantly (P < 0.05) contributed to dispensing errors, errors in communication, problems with efficiency and those similar problems were observed for all items relating to drive through window pick-up services. Automated dispensing systems were perceived as less likely (P < 0.05) to contribute to dispensing errors, errors in communication, efficiency problems and extra physical movement. Perceived dispensing error rate was 0.057%, and the number of dispensing errors was positively and significantly (P < 0.001) correlated with prescription volume. Cognitive errors accounted for approximately 80% of the dispensing errors. Perceptions of dispensing errors by pharmacists are influenced by design, drive through pick-up window services, and automated dispensing systems. However, more effort is needed to determine how cognitive processes relate to sociotechnical variables in pharmacy practice and other environments.

Cross-sectional descriptive study. Farming communities across Australia. Data of men (n = 957) and women (n = 835) farmers from 97 locations across Australia were stratified into categories based on National Cholesterol Education Program guidelines.   Prevalence of and interrelationship between overweight, obesity, dyslipidaemia, hypertension, diabetes risk and psychological distress. There was a higher prevalence of overweight (42.5%, 95% confidence interval (CI), 34.2-50.8), obesity (21.8%, 95% CI, 18.3-25.3), abdominal adiposity (38.4% 95% CI, 24.5-52.5), hypertension (54.0%, 95% CI, 34.4-73.5) and diabetes risk (25.3%, 95% CI, 17.7-36.7) in the farming cohort compared with national data. There was also a positive significant association between the prevalence of psychological distress and obesity, abdominal adiposity, body fat percentage and metabolic syndrome in older (age ≥ 50 years) participants. This study group of farming men and women exhibited an increased prevalence of CVD risk factors and co-morbidities. The findings indicate a positive association between psychological distress and risk for developing CVD, particularly in the older farmers. If the younger cohort were to maintain elevated rates of psychological distress, then it is foreseeable that the next generation of farmers could experience poorer physical health than their predecessors. © 2012 The Authors.

    The exponential increase in the incorporation of health technologies has been considered a key factor in increased expenditures by the health sector. Such decisions involve multiple levels and stakeholders. Decentralization has multiplied the decision-making levels, with numerous difficult choices and limited resources. The interrelationship between stakeholders is complex, in creative systems with multiple determinants and confounders. The current review discusses the interaction between the factors influencing the decisions to incorporate technologies by health services, and proposes a structure for their analysis. The application and intensity of these factors in decision-making and the incorporation of products and programs by health services shapes the installed capacity of local and regional networks and modifies the health system. Empirical observation of decision-making and technology incorporation in Brazilian health services poses an important challenge. The structured recognition and measurement of these variables can assist proactive planning of health services.

    This study examines how different information sources relate to Health Belief Model (HBM) constructs, hepatitis B virus (HBV) knowledge, and HBV screening. The Maryland Asian American Liver Cancer Education Program administered a survey of 877 Asian immigrants. The most common sources of information identified by the multiple-answer questions were newspapers (39.8%), physicians (39.3%), friends (33.8%), TV (31.7%), and the Internet (29.5%). Path analyses—controlling for age, sex, educational level, English proficiency, proportion of life in U.S., health insurance coverage, and family history of HBV infection—showed that learning about HBV from physicians had the strongest direct effect; friends had a marginal indirect effect. Perceived risk, benefits, and severity played limited roles in mediation effects. Path analysis results differed by ethnicity. Physician-based HBV screening intervention would be effective, but should be complemented with community health campaigns through popular information sources for the uninsured. PMID:23238580

    A personal trait, for example a person's cognitive ability, represents a theoretical concept postulated to explain behavior. Interesting constructs are latent, that is, they cannot be observed. Latent variable modeling constitutes a methodology to deal with hypothetical constructs. Constructs are modeled as random variables and become components of a statistical model. As random variables, they possess a probability distribution in the population of reference. In applications, this distribution is typically assumed to be the normal distribution. The normality assumption may be reasonable in many cases, but there are situations where it cannot be justified. For example, this is true for criterion-referenced tests or for background characteristics of students in large scale assessment studies. Nevertheless, the normal procedures in combination with the classical factor analytic methods are frequently pursued, despite the effects of violating this "implicit" assumption are not clear in general. In a simulation study, we investigate whether classical factor analytic approaches can be instrumental in estimating the factorial structure and properties of the population distribution of a latent personal trait from educational test data, when violations of classical assumptions as the aforementioned are present. The results indicate that having a latent non-normal distribution clearly affects the estimation of the distribution of the factor scores and properties thereof. Thus, when the population distribution of a personal trait is assumed to be non-symmetric, we recommend avoiding those factor analytic approaches for estimation of a person's factor score, even though the number of extracted factors and the estimated loading matrix may not be strongly affected. An application to the Progress in International Reading Literacy Study (PIRLS) is given.

    Objective: To explore the relevant factors of behavioral development among 30-month-old infants in rural area, Shaanxi Province. Methods: The behavioral development among 977 infants aged 30-month-old was evaluated in Changwu and Binxian of Shaanxi province from July 2006 to August 2008. The inclusion criteria included single live birth between January 2004 and February 2006, mother had participated in a community-based intervention study named "Impact of multi-micronutrient supplementation during pregnancy on low birth weight and premature delivery" . Infants who had obvious deformity or other birth defects, infants who could not complete the questionnaire survey, physical examination were excluded from the study. The self-designed questionnaire was used to investigate the information of feeding patterns, disease status, physical development, and immunization status of the infants, and their behavioral development were assessed by Bayley scales of infant development (BSID). General Linear Model was used to adjust the possible confounding factors, and the analysis of variance was performed to explore the effects on the behavioral development among infants aged 30-month-old. Results: Among the infants in the study, the average age was (30.6±0.6) months old, the mean birth weight was (3 199.1±405.9)g. After adjusted the mothers' age of delivery, educational level and occupation of the parents, family ecnomic conditions and the number of children, infants whose mother exposed to toxic chemicals during pregnancy had lower score in activity (-0.179±0.961) and lower score in concentration (-0.177±1.099) compared with infants with unexposed mother (0.058±1.006, P=0.001; 0.057±0.960, P=0.003). Similarly, infants whose mother took drugs during pregnancy had lower score in persistent behaviors (-0.070±1.000) compared with infants whose mother did not(0.085±1.006, P=0.017). Compared with normal birth infants(0.043±0.981, P=0.007; 0.021±0.984, P=0.034), infants less

  2. Genes, epigenetic regulation and environmental factors: which is the most relevant in developing autoimmune diseases?

    Autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis and inflammatory bowel disease, have complex pathogeneses and likely multifactorial etiologies. The current paradigm for understanding their development is that the disease is triggered in genetically-susceptible individuals by exposure to environmental factors. Some of these environmental factors have been specifically identified, while others are hypothesized and not yet proven, and it is likely that most have yet to be identified. One interesting hypothesis is that environmental effects on immune responses could be mediated by changes in epigenetic regulation. Major mechanisms of epigenetic gene regulation include DNA methylation and histone modification. In these cases, gene expression is modified without involving changes in DNA sequence. Epigenetics is a new and interesting research field in autoimmune diseases. We review the roles of genetic factors, epigenetic regulation and the most studied environmental risk factors such as cigarette smoke, crystalline silica, Epstein-Barr virus, and reproductive hormones in the pathogenesis of autoimmune disease.

    Background/Introduction: Current telestroke network consultations are focused on decision-making in the hyperacute stage of stroke management. The two main questions in telestroke consultations are whether thrombolysis should be initiated and whether the patient should be transferred to a hub hospital. Although guidelines exist for initiating intravenous thrombolytic therapy, the question of whether patients should be transferred is far more elusive. In this study, we investigated the factors involved in the decision to transfer stroke patients to a hub hospital. We were particularly interested in identifying factors that promote or impede the transfer of patients. We enrolled 1,615 cases of telestroke consultation of the University Hospital Jena. The two main factors that independently influenced the probability of transferring a patient were the patient's age and the identification of a proximal vessel occlusion. Interestingly, factors such as the severity of symptoms and the time elapsed from symptom onset were not found to have an independent influence on the decision to transfer a patient. The transfer of most patients was justified by the possibility of performing interventional reperfusion therapy. We discuss the effectiveness of the current decision-making process and possible ways to improve decision-making for a more effective selection of patients who would benefit from transfer. The decision-making process to a transfer patient is not standardized and constitutes a trade-off between the intention to treat all possible patients while avoiding the transfer of patients without treatment options.

    A relatively new mobile technological device is the smartphone—a phone with advanced features such as Windows Mobile software, access to the Internet, and other computer processing capabilities. This article investigates the decision to adopt a smartphone among healthcare professionals, specifically nurses. The study examines constructs that affect an individual's decision to adopt a smartphone by employing innovation attributes leading to perceived attitudes. We hypothesize that individual intentions to use a smartphone are mostly determined by attitudes toward using a smartphone, which in turn are affected by innovation characteristics. Innovation characteristics are factors that help explain whether a user will adopt a new technology. The study consisted of a survey disseminated to 200 practicing nurses selected from two community hospitals in the southeastern United States. In our model, the innovation characteristics of observability, compatibility, job relevance, internal environment, and external environment were significant predictors of attitude toward using a smartphone.

    Investigating risk factors for anti-social behavior (ASB) is particularly relevant in a poor urban and violent community of a developing country where homicide is the primary cause of death among 15-24-year olds. To identify individual and environmental factors associated with ASB in adolescents from an urban poor community in the outskirts of São Paulo City, Brazil. This cross-sectional study was based on a probabilistic sample of clusters that included all eligible households (women aged 15-49 years with a son or daughter <18 years of age). One mother-child pair was randomly selected per household (n = 813; response rate: 82.4%). This study is focused on the age group 11-17 years (n = 248). ASB was identified by externalizing scores in the clinical range on the Child Behavior Checklist and/or the Youth Self Report. Potential correlates included individual, maternal, paternal, and familial characteristics. Backward logistic regression analysis identified independent correlates and significant interactions. Youths with high ASB scores were more likely to be victims of severe physical punishment and have an absent father/substitute. Maternal anxiety/depression was a risk factor only among older adolescents (15-17 years), while the presence of internalizing problems was a risk factor only among younger adolescents (11-14 years). Having a non-working mother increased the risk for ASB only among low-income adolescents. The recognition that certain environmental factors may have harmful effects on adolescents' mental health, and the identification of more vulnerable groups can contribute to the development of effective strategies for prevention and treatment of ASB.

    With the increasing prevalence of obesity, there is a continuous search for effective obesity-prevention and health-promotion interventions. These interventions should be based on factors that have the potential to influence body weight and health. This study describes various health-related factors in a Canadian university community with the aim of developing more specific obesity interventions. A total of 3143 individuals completed an online questionnaire made up of 3 sections--on physical activity (PA), food habits, and other relevant lifestyle factors. The sampling error was +/-3.3% with a 95% confidence interval. Results showed that 22.9% of students and 37.3% of staff members were either overweight or obese. Students had less desirable eating patterns than staff members in terms of fish, energy drink, and regular milk product intake, and both groups reported undesirable breakfast consumption and quality. Nevertheless, results also showed that a high percentage of individuals in both groups did not meet the recommendations for vegetable, fruit, and fish intake, or PA. Only a few gender differences were observed in eating habits. Soft drink and energy drink consumption was higher and breakfast consumption was lower in men, whereas a higher percentage of women did not meet the recommendations for vegetable, fruit, or fish consumption. Dieting behaviours, disinhibition susceptibility, and moderate-intensity (MIPA) were the 3 lifestyle factors most highly associated with overweight and obesity in both groups. Results also suggest that female students were highly preoccupied with their body weight. This study shows that overweight and obesity are problems in a university community, and that they are associated with many health-related lifestyle behaviours. Although most of the lifestyle factors and health measures examined are similar across groups and genders, some differences call for the development of health-promotion programs with specific targeting strategies.

  14. Susceptibility Factors Relevant for the Association Between Long-Term Air Pollution Exposure and Incident Asthma.

    2016-03-01

    In this review, we identified 15 studies in children and 10 studies in adults that assessed the association between long-term exposure to air pollution and incident asthma and that conducted stratified analyses to explore potential susceptibility factors. Overall, adult never-/former smokers seem to be at higher risk of incident asthma due to air pollution. Children without atopy and children from low socioeconomic status families also seem to be at higher risk of incident asthma due to air pollution. While interaction between air pollution and genes involved in the response to oxidative stress pathways have been explored, results are somewhat inconsistent and in need of replication. To evaluate interactions, large sample sizes are necessary, and much more research, including data pooling from existing studies, is needed to further explore susceptibility factors for asthma incidence due to long-term air pollution exposure.

    In this study radionuclide semi-liquid gastric emptying (GE) study was adopted to test the gastric motility in 129 patients with type 2 diabetes. Further study was made to explore the relationship between gastric motility disorder of diabetes and the influential factors. The variables to be measured and analyzed were age, BMI, duration of illness, level of glycemia, HbAlc, plasma insulin, motilin, gastrin, glucagon and Mg2+. Of the 129 cases, 80 had delayed GE with an occurrence of 62.02%, and there was a close correlation between gastric motility disorder and the duration of illness, BMI, FPG, PPG, serum insulin, motilin levels and HbAlc as well. These findings imply that gastric motility disorder of diabetes is influenced by multiple factors. The results also suggest that gastric motiligy disorder is much more common than expected, and radionuclide gastric emptying test is a useful aid for the early detection of this clinical entity.

    The influence hemostatitc parameters on the morphological extent and severity of coronary artery disease were studied in patients with and without DM type 2. It is known that patients with diabetes (DM) have abnormal metabolic and hemostatic parameters Of 150 consecutive patients with angiographically proven coronary artery disease 29 presented with DM. Additionally to parameters of lipid-metabolism fibrinogen, tissue-plasminogenactivator (t-PA), plasminogen-activator-inhibitor (PAI), plasmin-a-antiplasmin (PAP), prothrombin-fragment 1+2 (F1+2), thrombin-antithrombin (TAT), von-willebrand-factor (vWF), platelet factor 4 (PF4), glykomembranproteine 140 (GMP140) and the rheologic parameters plasma viscosity and red blood cell aggregation were evaluated. The extent and severity of CAD was evaluated according to the criteria of the American Heart Association. Patients with DM presented with a higher number of conventional risk factors as compared to non-diabetic patients. Additionally there were significant differences for F1+2, red blood cell aggregation and PAI. Diabetic patients showed a more severe extent of coronary arteriosclerosis, which also could be found more distally. A significant relationship between blood-glucose, thrombocyte-activation (vWF), endogenous fibrinolysis (PAI) and the severity of CAD and a more distal location of stenoses could be found (r = 0.6, p < 0.001). Patients with coronary artery disease and DM type 2 showed marked alterations of metabolic, hemostatic, fibrinolytic and rheologic parameters, which can produce a prothrombogenic state. A direct association of thrombogenic factors on coronary morphology could be shown. This can be the pathophysiologic mechanism of more severe and distal pronounced coronary atherosclerosis in these patients.

    2016-01-01

    Genetic factors contribute for about 70% to 80% and environmental factors for about 20% to 30% to the pathogenesis of autoimmune thyroid disease (AITD). Relatives of AITD patients carry a risk to contract AITD themselves. The 5-year risk can be quantified by the so-called Thyroid Events Amsterdam-score, based on serum thyroid-stimulating hormone, thyroid peroxidase (TPO)-antibodies and family history. Subjects at risk may ask what they can do to prevent development of AITD. This review summarizes what is known about modulation of exposure to environmental factors in terms of AITD prevention. To stop smoking decreases the risk on Graves disease but increases the risk on Hashimoto disease. Moderate alcohol intake provides some protection against both Graves and Hashimoto disease. Low selenium intake is associated with a higher prevalence of thyroid autoimmunity, but evidence that selenium supplementation may lower TPO antibodies and prevent subclinical hypothyroidism remains inconclusive. Low serum vitamin D levels are associated with a higher prevalence of TPO antibodies, but intervention studies with extra vitamin D have not been done yet. Stress may provoke Graves hyperthyroidism but not Hashimoto thyroiditis. Estrogen use have been linked to a lower prevalence of Graves disease. The postpartum period is associated with an increased risk of AITD. Taking together, preventive interventions to diminish the risk of AITD are few, not always feasible, and probably of limited efficacy. PMID:27184015

    Early detection of emergent influenza strains is a global health priority. However, maintaining active surveillance is economically and logistically challenging. While community-based surveillance is an attractive alternative, design and operation of an effective epidemiological surveillance program requires community engagement that can be linked to public health reporting and response. We report the results of a study in rural Guatemalan communities aimed at identifying opportunities for and barriers to community engagement in disease surveillance. Using an ethnographic approach followed by a descriptive cross-sectional survey, we documented local terms and ideas about animal illnesses, including the possibility of animal-human transmission. The community perceived disease causation principally in terms of changes in the physical environment and weather and categorized illnesses using local terminology based on observable clinical signs. Knowledge about prevention and treatment was derived predominantly from local networks of family and friends without evidence of professionally-based knowledge being regularly introduced into the community. Bridging the divide between professional and community-based descriptive disease terminology, incorporating animal and human health responsiveness to common illnesses, and providing professional knowledge into the community-based networks were identified as addressable challenges to effective implementation of community-based surveillance.

    The effect of inhaled drugs in community-acquired pneumonia (CAP) is unclear. This case-control study was designed to determine whether inhaled drugs were risk factors for CAP. All incident cases of confirmed CAP that occurred over 1 yr in patients with chronic bronchitis (CB), chronic obstructive pulmonary disease (COPD) or asthma were included, as well as CB, COPD and asthma controls. Risk factors for CAP and inhaled treatment were recorded during a personal interview. An effect of inhaled drugs on the risk of CAP was observed in COPD and asthma patients after adjusting for the effect of other respiratory diseases and their concomitant treatments. In COPD patients, inhaled steroids had a risk OR of 3.26 (95% CI 1.07-9.98) and in asthma patients inhaled anticholinergics had a risk OR of 8.80 (95% CI 1.02-75.7). In CB patients, no association with CAP was observed for any inhaler. These effects were independent of adjusting variables related to severity and other respiratory and non-respiratory risk factors for CAP, including vaccines. Inhaled β(2)-adrenergic agonists did not show a significant effect on the risk of CAP in any of the respiratory diseases. Inhaled steroids may favour CAP in COPD patients, whereas anticholinergics may favour CAP in asthma patients. It is difficult to differentiate the effect of inhaled therapy from the effect of COPD or asthma severity on the risk of CAP, and these relationships may not be causal, but could call attention to inhaled therapy in COPD and asthma patients.

On average, the elderly experienced 0.3 falls over the preceding three months. A fall was seen to cause a significant deterioration in the quality of life and vertigo and caused fear of falling. The postural instability correlated with falls. Vertigo was present among 42% and was most commonly characterized as episodic and rotatory in factorial analysis items relating to vertigo correlated to falls and balance complaints. Four factors were identified and three of these correlated with falls. Vestibular failure correlated to a fall occurring when a person was rising up; Movement intolerance correlated with falls due to slips and trips, and Near-syncope factor correlated to falls for other reasons. In posturography, the variable measuring critical time describing the memory based "closed loop" control of postural stability carried a risk for accidental fall with an odds ratio of 6. The variable measuring zero crossing velocity showed a high rate of velocity change around the neutral position of stance. Vertigo and poor postural stability were the major reasons for falls in the active elderly. In ageing, postural control is shifted towards open loop control (visual, proprioception, exteroception and vestibular) instead of closed loop control and is a factor that contributes to a fall.

    Many interventions seeking to reduce problem behaviors and promote healthy youth development target both risk and protective factors, yet few studies have examined the effect of preventive interventions on overall levels of protection community wide. In a community-randomized controlled trial, this study tested the effect of Communities That Care (CTC) on protective factors in 24 communities across 7 states. Data on protective factors were collected from a panel of 4,407 youths in CTC and control communities followed from Grade 5 through Grade 8. Hierarchical linear modeling compared mean levels of 15 protective factors derived from the social development model in CTC and control communities in Grade 8, adjusted for individual and community characteristics and baseline levels of protective factors in Grade 5. Global test statistics were calculated to examine effects on protection overall and by domain. Analyses across all protective factors found significantly higher levels of overall protection in CTC compared to control communities. Analyses by domain found significantly higher levels of protection in CTC than control communities in the community, school, and peer/individual domains, but not in the family domain. Significantly higher levels of opportunities for prosocial involvement in the community, recognition for prosocial involvement in school, interaction with prosocial peers, and social skills among CTC compared to control youth contributed to the overall and domain specific results. This is consistent with CTC’s theory of change, which posits that strengthening protective factors is a mechanism through which CTC prevents behavior problems. PMID:25366931

  6. Recognition of the mycobacterial cord factor by Mincle: relevance for granuloma formation and resistance to tuberculosis

    2012-01-01

    The world's most successful intracellular bacterial pathogen, Mycobacterium tuberculosis (MTB), survives inside macrophages by blocking phagosome maturation and establishes chronic infection characterized by the formation of granulomas. Trehalose-6,6-dimycolate (TDM), the mycobacterial cord factor, is the most abundant cell wall lipid of virulent mycobacteria, is sufficient to cause granuloma formation, and has long been known to be a major virulence factor of MTB. Recently, TDM has been shown to activate the Syk-Card9 signaling pathway in macrophages through binding to the C-type lectin receptor Mincle. The Mincle-Card9 pathway is required for activation of macrophages by TDM in vitro and for granuloma formation in vivo following injection of TDM. Whether this pathway is also exploited by MTB to reprogram the macrophage into a comfortable niche has not been explored yet. Several recent studies have investigated the phenotype of Mincle-deficient mice in mycobacterial infection, yielding divergent results in terms of a role for Mincle in host resistance. Here, we review these studies, discuss possible reasons for discrepant results and highlight open questions in the role of Mincle and other C-type lectin receptors in the infection biology of MTB.

    The authors examined the relation between smoking status and fruit and vegetable (FV) consumption among a population-based sample and examined differences in psychosocial factors that may influence diet and inform intervention efforts. The authors recruited adults (N = 2,540) from 5 US health plans to participate in a Web-based dietary intervention trial. At baseline, smokers ate fewer FV servings per day (p < .001) and were less likely to meet the 5 A Day goal (p < .001). Smokers reported lower self-efficacy, overall motivation, and intrinsic motivation for meeting daily FV recommendations. Fewer smokers expected that eating 5 FV servings a day would reduce their risk for diabetes (p = .02) or obesity (p = .008). Smokers are an important target group for dietary intervention. Intervention efforts should attempt to increase smokers' motivation and confidence in their abilities to change their eating patterns and educate them about the health benefits of eating FV.

    Therapy for recurrent Clostridium difficile-associated diarrhea (CDAD) is challenging. We evaluated the frequency, associated risk factors, and prognosis of first CDAD recurrences. Prospective cohort study of all consecutive cases of primary CDAD diagnosed in a university hospital from January 2006 to June 2013. Recurrent infection was defined as reappearance of symptoms within 8 weeks of the primary diagnosis, provided that CDAD symptoms had previously resolved and a new toxin test was positive. Predictors of a first episode of recurrent CDAD were determined by logistic regression analysis. In total, 502 patients (51.6 % men) with a mean age of 62.3 years (SD 18.5) had CDAD; 379 (76 %) were cured, 61 (12 %) had a first recurrence, 52 (10 %) died within 30 days of the CDAD diagnosis, nine (2 %) required colectomy, and one was lost to follow-up. Among the 61 patients with a first recurrence, 36 (59.3 %) were cured, 15 (23.7 %) had a second recurrence, nine (15.3 %) died, and one (1.7 %) required colectomy. On multivariate analysis, age older than 65 years (OR 2.04; 95 % CI, 1.14-3.68; P < 0.02) and enteral nutrition (OR, 3.62; 95%CI, 1.66-7.87; P < 0.01) were predictors of a first recurrence. A risk score was developed for first CDAD recurrence using the predictive factors and selected biological variables. In our CDAD cohort, 12 % of patients had a first recurrence of this disease, in which the prognosis was less favorable than that of the primary episode, as it heralded a higher risk of additional recurrences. Patient age and enteral nutrition were predictors of a first recurrence.

    In June 2012, fishes was investigated at 65 sampling sites in the Huntai River basin in Northeast of China. Forty species were collected, belonging to 9 orders, 14 families,33 genera. Cobitidae and Cyprinidae were the dominant fishes in the community structure in the Huntai River basin, accounting for 13. 21% and 65. 83% of the fish community, respectively. There were two types of spatial distribution of fish community, one was distributed in the head water and tributaries in the upstream, and the other was in the plain rivers. Nemachilus nudus, Cobitis granoei and Phoxinus lagowskii dominated the local community in the upper reaches of the Dahuofang Reservoir and shenwo River, while Carassius ayratus and Hemiculter leucisculdus dominated the local community in the plain rivers. CCA (canonical correspondence analysis) was used to distinguish the primary environmental variables that affected the fish community structure. The results indicated fish community was mainly affected by environment factors at watershed and reach scales. Proportions of woodland and urban land, and altitude were three important environmental factors affecting the fish community at the watershed scale. Dissolved oxygen, total nitrogen, pH and habitat inhomogeneity significantly affected the fish community at the reach scale, whereas substrate didn't show significant influence at the microhabitat scale. Environmental factors at watershed scale explained 7. 66% of the variation of fish community structure, environmental factors at reach scale explained 10. 57% of the variation of fish community structure. Environmental factors at reach scale influenced the fish community more significantly.

    Objective: To investigate the possible factors related to recurrence and prognosis of sudden sensorineural hearing loss(SSNHL). Methods: Four hundred and ninety-five patients with unilateral sudden sensorineural hearing loss between January 2013 to April 2014 were analyzed retrospectively(34 patients lost to follow-up with a dropout rate of 6.87%). Twenty of the 495 patients were diagnosed as recurrent SSNHL and treated again in the same hospital. The data of the patients were summarized to analyze the related factors which might influence the recurrence and prognosis of SSNHL. Results: In the 20 patients with recurrent SSNHL, 19 had the second attack in same ear as the first attack, and the other one had in both ears. There were seven male patients, and thirteen female patients. Patients ranged in age from 24 to 77years, with a median age of 39.5 years. Types of hearing loss: low frequency in eight patients, high frequency in two patients, flat frequency in eight patients, total deafness in two patients, the types of the second attack in 17 patients were same as the first attack, only one patient was changed from total deafness to flat frequency, one case was changed from flat frequency to high frequency, one case changed from flat frequency to total deafness. The intervals between of the first attack time and the second attack time were 1-36 months with the median time of 3.5 months. After systemic oral and (or) transtympanic steroid treatment, recovered in three cases, effective in three cases and 14 cases invalid, the cure rate was 15%, and the total effective rate was 30%. There were statistically significant differences in the recovery rate(χ(2)=8.640, P<0.05) and the overall response rate(χ(2)=12.379, P<0.01)between the first and the second treatments. For the patients with vertigo and/or dizziness, with a history more than seven days, with hypertension or diabetes mellitus, and with a type of hearing loss except low frequency type, the treatment effect

    Resistant hypertension, defined as blood pressure >140/90 mm Hg despite using ≥3 antihypertensive medications, is a well-recognized clinical entity. Patients with resistant hypertension are at an increased risk of cardiovascular disease compared with those with more easily controlled hypertension. Coronary heart disease mortality rates of younger adults are stagnating or on the rise. The purpose of our study was to characterize the phenotype and risk factors of younger patients with resistant hypertension, given the dearth of data on cardiovascular risk profile in this cohort. We conducted a cross-sectional analysis with predefined age groups of a large, ethnically diverse cohort of 2170 patients referred to the Hypertension Clinic at the University of Alabama at Birmingham. Patients (n=2068) met the inclusion criteria and were classified by age groups, that is, ≤40 years (12.7% of total cohort), 41 to 55 years (32.1%), 56 to 70 years (36.1%), and ≥71 years (19.1%). Patients aged ≤40 years compared with those aged ≥71 years had significantly earlier onset of hypertension (24.7±7.4 versus 55.0±14.1 years; P<0.0001), higher rates of obesity (53.4% versus 26.9%; P<0.0001), and significantly higher levels of plasma aldosterone (11.3±9.8 versus 8.9±7.4 ng/dL; P=0.005), plasma renin activity (4.9±10.2 versus 2.5±5.0 ng/mL per hour; P=0.001), 24-hour urinary aldosterone (13.4±10.0 versus 8.2±6.2 µg/24 h; P<0.0001), and sodium excretion (195.9±92.0 versus 146.8±67.1 mEq/24 h; P<0.0001). Among patients with resistant hypertension, younger individuals have a distinct phenotype characterized by overlapping risk factors and comorbidities, including obesity, high aldosterone, and high dietary sodium intake compared with elderly. © 2017 American Heart Association, Inc.

    Malaria parasite prevalence in endemic populations is an essential indicator for monitoring the progress of malaria control, and has traditionally been assessed by microscopy. However, surveys increasingly use sensitive molecular methods that detect higher numbers of infected individuals, questioning our understanding of the true infection burden and resources required to reduce it. Here we analyse a series of data sets to characterize the distribution and epidemiological factors associated with low-density, submicroscopic infections. We show that submicroscopic parasite carriage is common in adults, in low-endemic settings and in chronic infections. We find a strong, non-linear relationship between microscopy and PCR prevalence in population surveys (n=106), and provide a tool to relate these measures. When transmission reaches very low levels, submicroscopic carriers are estimated to be the source of 20–50% of all human-to-mosquito transmissions. Our findings challenge the idea that individuals with little previous malaria exposure have insufficient immunity to control parasitaemia and suggest a role for molecular screening. PMID:23212366

    The significance of age factor for the development of radiation pneumonitis is evaluated in 62 patients with lung cancer between 1977 and 1985. The younger group consists of those less than 70 years old and the elderly group of those 70 years old or more. Radiation doses ranged from 1.5 to 2 Gy, 3 to 5 times per week, therefore the delivered doses were converted to nominal single doses (rets dose). Severe radiation pneumonitis was more often observed in the elderly than in the younger regardless of radiation field size and chemotherapy (n.s.). The onset of radiation pneumonitis occurred earlier in a field size of 90 sq cm or more than in that of less than 90 sq cm in both age groups; there was no significant difference between the two age groups in each field size. The pneumonitis was more frequently noted with increasing rets dose in both age groups (n.s.) regardless of field size and chemotherapy. It is concluded that there is no significant difference in the development of radiation pneumonitis between the younger group and the elderly group, but the pneumonitis is inclined to be more severe in the latter.

  15. How therapeutic communities work: Specific factors related to positive outcome

    2012-01-01

    Background Therapeutic communities (TCs) are becoming increasingly widespread as a form of treatment for entrenched mental health problems, particularly addictions and personality disorders, and are equally used in educational, prison and learning disability settings. Despite growing evidence for their effectiveness, little research has been conducted to establish how TCs work to produce positive outcomes. We hypothesize that there are two specific factors that in combination contribute to TC effectiveness: the promotion of a sense of belongingness and the capacity for responsible agency. Although both factors are found in other therapeutic approaches and are important to the psychosocial aspects of psychiatric care more generally, we argue that their combination, extent and emphasis are unique to TCs. Material Drawing on social and experimental psychology, we: (1) review research on a sense of belongingness and the capacity for responsible agency; (2) establish the mechanisms by which TCs appear to promote them; (3) draw lessons for TC practice; and (4) suggest why they may contribute to positive outcome. Discussion A sense of belongingness is correlated with improved self-esteem and overall well-being. The capacity for responsible agency is central to behavioural change. TCs are typically used in fields where positive outcome requires both personal growth and behavioural change. We suggest that TCs are uniquely placed to demand such growth and change of their members because the sense of belongingness engendered by TC methods protects against the risks engendered by this demand. Conclusion Empirically informed, evidence-driven research is necessary to understand how TCs work and how TC practice can be improved. This understanding may offer lessons for the improvement of psychosocial aspects of psychiatric care more generally. PMID:22820178

    Management and supervision of community health workers are factors that are critical to the success of community health worker programmes. Yet few studies have explored the perspectives of supervisors in these programmes. This study explored factors influencing motivations of supervisors in community health worker programmes. We conducted qualitative interviews with 26 programme staff providing supervision to community health workers in eight community-based organizations in marginalized communities in the greater Durban area of South Africa from July 2010 to September 2011. Findings show that all the supervisors had previous experience working in the health or social services sectors and most started out as unpaid community health workers. Most of the participants were poor women from marginalized communities. Supervisors' activities include the management and supply of material resources, mentoring and training of community health workers, record keeping and report writing. Supervisors were motivated by intrinsic factors like making a difference and community appreciation and non-monetary incentives such as promotion to supervisory positions; acquisition of management skills; participation in capacity building and the development of programmes; and support for educational advancement like salary, bonuses and medical benefits. Hygiene factors that serve to prevent dissatisfaction are salaries and financial, medical and educational benefits attached to the supervisory position. Demotivating factors identified are patients' non-adherence to health advice and alienation from decision-making. Dissatisfiers include working in crime-prevalent communities, remuneration for community health workers (CHWs), problems with material and logistical resources, job insecurity, work-related stressors and navigating the interface between CHWs and management. While participants were dissatisfied with their low remuneration, they were not demotivated but continued to be motivated

    We sought to explore clinical factors associated with successful transition from Assertive Community Treatment to less intensive clinical services. Mixed-method observational follow up study of veterans discharged from three VA-affiliated ACT teams to less intensive clinical services. Of the 240 veterans in ACT, 9% (n = 21) were discharged during the study period. Among the 11 of 21 discharged veterans who enrolled in the follow up study, reason for discharge, designated by the veteran's primary clinician at the time of discharge, predicted outcomes (p = 0.02) at 9 months, with "disengagement" as a reason for discharge predicting poorer outcomes. Six of 11 veterans experienced poor outcomes at 9 months, including incarceration and substance use relapse. ACT clinicians rarely discharge clients. Many clients may experience negative clinical events following ACT discharge, and clients may be difficult to follow post-discharge. Client disengagement from ACT may indicate higher likelihood of poor outcomes following discharge to less intensive clinical services.

    The Joint Commission's 2014 National Patient Safety Goals required hospitals to evaluate alarm safety in 2014-2015 and implement alarm safety policies. The aim of this study was to assess common alarm management safety factors in our 187-bed community hospital. Two weeks' worth of IV pump report data was evaluated to characterize 33 IV pump alarm types. Hospital and IV pump noise was measured, and an alarm management nurse survey was conducted. There were 8731 total IV pump alarms/alerts (24-hour mean, 623.6) across 6 units. The 2-minute idle alarm accounted for 32.4% of all total IV alarms/alerts, suggestive of high levels of nurse multitasking and nurse work interruptions. IV pump volumes contributed to overall hospital noise. Survey data identified patient units and alarm safety practices needing additional support. Characterization of IV pump alarms/alerts is an emerging area of scientific inquiry. Findings indicate the need for organizations to evaluate alarm burden and alarm management safety practices to reduce alarm fatigue risks.

    Laboratory confirmation of the causative agent(s) of diarrhoea in puppies may allow for appropriate treatment. The presence of potential pathogens however, does not prove a causal relationship with diarrhoea. The aim of this study was to identify specific enteropathogens in ≤12 month old puppies with and without acute diarrhoea and to assess their associations with clinical signs, putative risk factors and pathogen co-occurrence. Faecal samples from puppies with (n=113) and without (n=56) acute diarrhoea were collected and screened for Canine Parvovirus (CPV), Canine Coronavirus (CCoV), Salmonella spp., Campylobacter spp., Clostridium perfringens, Clostridium difficile, β-hemolytic Eschericha coli (hEC), Giardia spp., Toxocara spp., Cystoisospora spp., and Cyniclomyces guttulatus. One or more pathogens were detected in 86.5% of diarrhoeic puppies and in 77.8% of asymptomatic puppies. Significant positive associations were found between CPV and CCoV, CPV and Cystoisospora spp., Toxocara spp. and hEC, Giardia spp. and C. guttulatus. Only CPV and CCoV were significantly associated with diarrhoea, hEC with a subset of puppies that had diarrhoea and severe clinical signs. CPV was more prevalent in puppies under 3 months of age. Puppies from high-volume dog breeders were significantly at increased risk for CPV (OR 4.20), CCoV (OR 4.50) and Cystoisospora spp. (OR 3.60). CCoV occurred significantly more often in winter (OR 3.35), and CPV in winter (OR 3.78) and spring (OR 4.72) as compared to summer. We conclude that routine screening for CPV, CCoV and hEC is recommended in puppies with acute diarrhoea, especially if they are under 3 months of age and originate from high-volume dog breeders. Routine screening for other pathogens may lead to less conclusive results.

    Background: Aggression is defined as behaviors intended to hurt, harm, or injure another person. Aggression is by no means a new concern in human society, especially in youth. Universities are among the institutions in which most of the members are young people and because of facing with various personal and social stressors, the students usually experience high level of stress. Objectives: This study aimed to determine aggression among university students and its association with their personal, family, and social characteristics. Materials and Methods: This cross-sectional, analytic study was conducted on a representative sample (n = 809) of university students (1 state university and 2 private universities) locating in Gonabad, Iran in 2012. Using proportional to size stratified sampling, we selected the respondents and gathered the required data using a valid and reliable questionnaire. The data were entered into SPSS (version 20) and analyzed through t test, ANOVA, and regression model. Results: A total of 381 (47.2%) male and 428 (52.8%) female students participated in the study. Mean (SD) age of the respondents was 21.79 (2.86) years. Overall mean aggression score (SD) in the students was 72.45 (15.49) and this score for in dorm and out of dorm students was 74.31 (15.59) and 70.93 (15.23), respectively. There were significant associations between the mean aggression score of dormitory students and sex (P = 0.004), age (P = 0.044), and type of the university (P = 0.039). On the other hand, there was no significant association between all independent factors and mean aggression score of students living out of dorm. Conclusions: Regarding the control of aggressive behaviors, paying attention to male, young students living in dormitory, especially in non-governmental universities has the highest priority.

    Platelet-derived growth factor receptor alpha (PDGFRα) is believed to be associated with cell survival. We examined (i) whether PDGFRα blockade enhances the antitumor activity of taxanes in ovarian carcinoma and (ii) potential biomarkers of response to anti-PDGFRα therapy. PDGFRα expression in 176 ovarian carcinomas was evaluated with tissue microarray and correlated to survival outcome. Human-specific monoclonal antibody to PDGFRα (IMC-3G3) was used for in vitro and in vivo experiments with or without docetaxel. Gene microarrays and reverse-phase protein arrays with pathway analyses were performed to identify potential predictive biomarkers. When compared to low or no PDGFRα expression, increased PDGFRα expression was associated with significantly poorer overall survival of patients with ovarian cancer (P=0.014). Although treatment with IMC-3G3 alone did not affect cell viability or increase apoptosis, concurrent use of IMC-3G3 with docetaxel significantly enhanced sensitization to docetaxel and apoptosis. In an orthotopic mouse model, IMC-3G3 monotherapy had no significant antitumor effects in SKOV3-ip1 (low PDGFRα expression), but showed significant antitumor effects in HeyA8-MDR (high PDGFRα expression). Concurrent use of IMC-3G3 with docetaxel, compared with use of docetaxel alone, significantly reduced tumor weight in all tested cell lines. In protein ontology, the EGFR and AKT pathways were downregulated by IMC-3G3 therapy. MAPK and CCNB1 were downregulated only in the HeyA8-MDR model. These data identify IMC-3G3 as an attractive therapeutic strategy and identify potential predictive markers for further development. © 2013.

    The aim of this study was to investigate the characteristics associated with volunteerism and identify the factors that contributed to posttraumatic stress disorder symptoms among community volunteers following the Sewol ferry disaster in Korea. In total, 2,298 adults (aged 30-70 years) from the Jin-do area, where the Sewol ferry disaster occurred, participated in this study. A cross-sectional survey was conducted 1 month after the disaster. Posttraumatic stress disorder (PTSD), depression, and anxiety symptoms were assessed using the Impact of Events Scale Revised (IES-R), Center for Epidemiologic Studies Depression Scale (CES-D), and Beck Anxiety Inventory (BAI). Clinically relevant PTSD symptoms were observed in 151 (19.7%) community volunteers. Age, education, socioeconomic status, religion, and lifetime experiences of natural disasters were associated with volunteering following the disaster. Logistic regression analysis revealed that volunteering was a significant risk factor for the development of PTSD symptoms in this sample. Personal experience with property damage associated with a traumatic event, depression, and anxiety were also significantly associated with the PTSD symptoms of community volunteers. Our results suggest the need for assessment and mental health programs for community volunteers performing rescue work to prevent posttraumatic stress symptoms following a community disaster.

    Background—No cause has been determined for chest pain that is neither cardiac nor oesophageal in origin. 
Aims—To compare the prevalence of lifetime psychiatric disorders and current psychological distress in three consecutive series of patients with chronic chest or abdominal pain. 
Patients—Thirty nine patients with non-cardiac chest pain and no abnormality on oesophagogastroduodenoscopy, oesophageal manometry, and 24 hour pH monitoring; 22 patients with non-cardiac chest pain having endoscopic abnormality, oesophageal dysmotility, and/or pathological reflux; and 36 patients with biliary colic. 
Methods—The Diagnostic Interview Schedule and the 28 item General Health Questionnaire were administered to all patients. 
Results—Patients with non-cardiac chest pain and no upper gastrointestinal disease had a higher proportion of panic disorder (15%), obsessive-compulsive disorder (21%), and major depressive episodes (28%) than patients with gallstone disease (0%, p<0.02; 3%, p<0.02; and 8%, p<0.05, respectively). In contrast, there were no differences between patients with non-cardiac chest pain and upper gastrointestinal disease and patients with gallstone disease in any of the DSM-111 defined lifetime psychiatric diagnoses. Using the General Health Questionnaire, 49% of patients with non-cardiac chest pain without upper gastrointestinal disease scored above the cut off point (that is, more than 4), which was considered indicative of non-psychotic psychiatric disturbance, whereas only 14% of patients with gallstones did so (p<0.005). The proportions of such cases were however similar between patients with non-cardiac chest pain and upper gastrointestinal disease (27%) and patients with gallstones. 
Conclusions—Psychological factors may play a role in the pathogenesis of chest pain that is neither cardiac nor oesophagogastric in origin. Keywords: chest pain;  oesophageal manometry;  gastro-oesophageal reflux disease;  oesophageal p

    The growth factor receptor network (GFRN) plays a significant role in driving key oncogenic processes. However, assessment of global GFRN activity is challenging due to complex crosstalk among GFRN components, or pathways, and the inability to study complex signaling networks in patient tumors. Here, pathway-specific genomic signatures were used to interrogate GFRN activity in breast tumors and the consequent phenotypic impact of GRFN activity patterns. Novel pathway signatures were generated in human primary mammary epithelial cells by overexpressing key genes from GFRN pathways (HER2, IGF1R, AKT1, EGFR, KRAS (G12V), RAF1, BAD). The pathway analysis toolkit Adaptive Signature Selection and InteGratioN (ASSIGN) was used to estimate pathway activity for GFRN components in 1119 breast tumors from The Cancer Genome Atlas (TCGA) and across 55 breast cancer cell lines from the Integrative Cancer Biology Program (ICBP43). These signatures were investigated for their relationship to pro- and anti-apoptotic protein expression and drug response in breast cancer cell lines. Application of these signatures to breast tumor gene expression data identified two novel discrete phenotypes characterized by concordant, aberrant activation of either the HER2, IGF1R, and AKT pathways ("the survival phenotype") or the EGFR, KRAS (G12V), RAF1, and BAD pathways ("the growth phenotype"). These phenotypes described a significant amount of the variability in the total expression data across breast cancer tumors and characterized distinctive patterns in apoptosis evasion and drug response. The growth phenotype expressed lower levels of BIM and higher levels of MCL-1 proteins. Further, the growth phenotype was more sensitive to common chemotherapies and targeted therapies directed at EGFR and MEK. Alternatively, the survival phenotype was more sensitive to drugs inhibiting HER2, PI3K, AKT, and mTOR, but more resistant to chemotherapies. Gene expression profiling revealed a bifurcation pattern

    Using national data on Medicare beneficiaries and their caregivers (CGs), we investigated CG and care recipient (CR) factors associated with the likelihood of remaining in the community. We obtained data on 722 CG and CR dyads who lived in the community in 2011 from the National Study of Caregiving and the National Health Aging and Trend Study. We then used pooled data from 2011 to 2015 to track the CRs' likelihood of remaining in the community. Generalized Estimating Equation (GEE) analyses were used to assess the association between CG and CR factors and likelihood of community residence over five years. The GEE analyses showed that the strongest CR factors predicting continued community residence include lower CR age, higher CR ADL capabilities, not having dementia, and having a heightened sense of community. CG factors predicting continued community residence included reporting no physical difficulties from caregiving, and higher positive aspects of caregiving. In addition to widely found predictors of remaining in the community (e.g., CR age and dementia), psychosocial variables (CG positive aspects of caregiving, CR sense of community engagement) were also significant independent predictors. Interventions that emphasize not only traditional risk factors for placement, but also psychosocial factors such as promoting CG positive aspects of caregiving and strengthening CRs' linkages with their neighbors or community members deserves greater attention.

    Many studies have considered community-based forestry enterprises to be the best option for development of rural Mexican communities with forests. While some of Mexico's rural communities with forests receive significant economic and social benefits from having a community forestry enterprise, the majority have not formed such enterprises. The purpose of this article is to identify and describe factors limiting the formation of community forestry enterprise in rural communities with temperate forests in the Southern Mixteca region of Oaxaca, Mexico. The study involved fieldwork, surveys applied to Community Board members, and maps developed from satellite images in order to calculate the forested surface area. It was found that the majority of Southern Mixteca communities lack the natural and social conditions necessary for developing community forestry enterprise; in this region, commercial forestry is limited due to insufficient precipitation, scarcity of land or timber species, community members' wariness of commercial timber extraction projects, ineffective local governance, lack of capital, and certain cultural beliefs. Only three of the 25 communities surveyed have a community forestry enterprise; however, several communities have developed other ways of profiting from their forests, including pine resin extraction, payment for environmental services (PES), sale of spring water, and ecotourism. We conclude that community forestry enterprise are not the only option for rural communities to generate income from their forests; in recent years a variety of forest-related economic opportunities have arisen which are less demanding of communities' physical and social resources.

    Mosterman, Regina M

    2013-01-01

    To investigate the clinical relevance of absolute scaling in personality assessment, Hofstee and Ten Berge's (2004) biproportional scaling method was applied to 3 clinical samples and compared with relative scaling in traditional analyses. In the first sample, 80 psychotherapy clients provided self-reports as well as reports by 3 informants, resulting in 320 ratings of the Dutch short form of the MMPI (NVM). In the second sample, 96 psychotherapy clients provided self-reports and informant reports, resulting in 384 Five-Factor Personality Inventory (FFPI) ratings. In the third sample, 95 clients provided self-reports and informant reports, resulting in 380 ratings of the NEO Five-Factor Inventory (NEO-FFI). In Part I of the study, the personality structure based on biproportional scaling was examined by replicating Hofstee, Barelds, and Ten Berge (2006). In Part II, this personality structure as well as self-informant distances and self-informant likenesses were related to symptoms, personality pathology, and level of functioning. The results confirmed the presence of a general factor of personality in absolute scaling, which appears to reflect social fitness and the absence of severe psychopathology. This factor was significantly associated with fewer symptoms and better functioning in all 3 samples. The personality pathology results were only significant in the FFPI sample. Self-informant distance and self-informant likeness were primarily associated with symptoms. A relationship between poor social fitness and insecure early attachment was suggested in 3 case studies.

    To examine the role of the alternative general stress sigma factor sigma(B) on the resistance of Staphylococcus aureus to stresses of relevance to food preservation, with special emphasis on emerging technologies such as pulsed electric fields (PEF) and high hydrostatic pressure (HHP). S. aureus strain Newman and its isogenic DeltasigB mutant were grown to exponential and stationary growth phases and its resistance to various stresses was tested. The absence of the sigma(B) factor caused a decrease in the resistance to heat, PEF, HHP, alkali, acid and hydrogen peroxide. In the case of heat, the influence of the sigma(B) factor was particularly important, and decreases in decimal reduction time values of ninefold were observed as a result of its deficiency. The increased thermotolerance of the parental strain as compared with the sigB mutant could be attributed to a better capacity to sustain and repair sublethal damages caused by heat. sigma(B) factor provides S. aureus cells with resistance to multiple stresses, increasing survival to heat, PEF and HHP treatments. Results obtained in this work help in understanding the physiological mechanisms behind cell survival and death in food-processing environments.

    Accurate conceptualization and measurement of age-friendly community characteristics would help to reduce barriers to documenting the effects on elders of interventions to create such communities. This article contributes to the measurement of age-friendly communities through an exploratory factor analysis of items reflecting an existing US Environmental Protection Agency policy framework. From a sample of urban elders (n = 1,376), we identified 6 factors associated with demographic and health characteristics: access to business and leisure, social interaction, access to health care, neighborhood problems, social support, and community engagement. Future research should explore the effects of these factors across contexts and populations.

    ABSTRACT Background: Family caregivers are considered as hidden patients experiencing physical and mental disorders. This affects the quality of not only their lives but also the health care provided to patients.This study aimed to investigate the quality of life (QOL) and its related factors among the caregivers of patients undergoing hemodialysis. Methods: This systematic review was conducted based on the eight-step guidelines presented by the York University. The databases relevant to the medical field including Nursing and Allied Health, Web of Science, Scopus, Pubmed, Embase, PsycINFO and Psychology Library were used. Finally, 12 articles observing the inclusion criteria and with regard to the research questions were found. The data obtained from these articles were summarized, classified, and analyzed. Results: QOL among Family Caregivers of Patients on Hemodialysis is low, compared to the general population; however, their QOL is higher than the patients under their care. Factors relevant to the QOL for caregivers including age, gender, perceived social support, perceived burden of care, affliction with other diseases (lupus, hypertension, hypothyroidism and depression), intellectual understanding of the limitations of the patient’s disease in their daily life, employment of adaptation strategies, better marital relationships, accepting self and family relationship with the patient (mother and wife). Furthermore, the factors associated with care takers affecting the quality of caregivers’ lives were age, QOL and the type of treatment. Conclusions: Caregivers of patients undergoing hemodialysis enjoyed low QOL. Since there is a direct relationship between family caregivers’ quality and patients’ QOL, health care system and health policy makers should pay more attention to family caregivers. PMID:28670583

    The rates of obesity, diabetes, and heart disease in Native Americans and Alaska Natives far exceed that of the general US population. There are many postulating reasons for these excessive rates including the transition from a traditional to a contemporary diet. Although information on the dietary intakes of Native American and Alaska Native communities are limited, there seems to be a consensus that the Native American and Alaska Native diet is high in total fat, saturated fat, cholesterol, and sodium. Further information on the diet needs to be attained so that dietary interventions can effectively be implemented in these communities. An approach that is community based is proposed as the best solution to understanding the Native diet and developing culturally tailored interventions to sustainably improve diet. © 2012 Wiley Periodicals, Inc.

    US Hispanics have disproportionate rates of diabetes and other chronic diseases. We used the entertainment-education approach to develop a Spanish-language radio novella aimed at reducing risk factors for diabetes, obesity, and tobacco use. The approach is based on social cognitive theory and proposes modeling as a source of vicarious learning of outcome and efficacy expectations. The Hispanic population in Alabama increased by 145% between 2000 and 2010. Nearly one-quarter of Hispanics aged 18 to 64 live below the federal poverty level, and 49% are uninsured. Several lifestyle factors lead to poor health behaviors in this community. Radio is a popular medium among Hispanic immigrants. The single local Spanish-language radio station reaches a large proportion of the local community and several communities beyond. Through various methods, including workshops, review sessions, and other feedback mechanisms, we engaged stakeholders and community members in developing and evaluating a 48-episode radio novella to be broadcast as part of a variety show. We tracked participation of community members in all phases. Community members participated significantly in developing, broadcasting, and evaluating the intervention. The desired outcome - development of a culturally relevant storyline that addresses salient health issues and resonates with the community - was realized. Our approach to community engagement can serve as a model for other organizations wishing to use community-based participatory methods in addressing Hispanic health issues. The radio novella was a unique approach for addressing health disparities among our community's Hispanic population.

    The purpose of this study was to clarify the role of community factors in parents' quality of child-nurturing life (QCNL). We developed a questionnaire to evaluate the degree of QCNL and determine the structural factors related to QCNL as community factors related to parents' QCNL derived from focus group interviews and the Delphi technique. The questionnaire also included the battery of the self-rating depression scale and Tsumori-Inage Infant's Developmental Test. Using the questionnaire, we then conducted a quantitative survey of parents whose children attended nursery schools in Kumamoto Prefecture. Factor analysis, calculation of the mean score and/or ratio to each item, Pearson's correlation coefficient, t test, multiple regression analysis, and covariance structure analysis were performed. The questionnaire we developed consisted of seven items with 75 elements, involving ten elements as community factors. Subjects included 699 parents (mean age 33.6 ± 5.4 years) and 965 children (age range 0-6 years). Factor analysis revealed that community factors consisted of five factors, such as "lifestyle rooted in the ground," "balance of housekeeping and work," "community network," "amenity," and "regeneration of life". These factors may be dominant in a rural area. Finally, we developed a structural model with "community factors," QCNL, QOL, and "child growth" by covariance structural analysis. The analysis revealed that community factors had a positive relation to parents' QCNL (r = 0.81, p < 0.001) and that parental SDS score had a negative relation to parents' QCNL (r = -0.59, p < 0.001). The analysis did show that community factors were positively related to the sound growth of children. The covariance structure analysis revealed that community factors were associated with parents' QCNL, SDS, and "child growth."

    Liese, Angela D; Hibbert, James D; Ma, Xiaoguang; Bell, Bethany A; Battersby, Sarah E

    Several recent United States (US) policies target spatial access to healthier food retailers. We evaluated two measures of community food access developed by two different agencies, using a 2009 food environment validation study in South Carolina as a reference. While the US Department of Agriculture Economic Research Service's (USDA ERS) measure designated 22.5% of census tracts as food deserts, the Centers for Disease Control and Prevention's (CDC) measure designated 29.0% as non-healthier retail tracts; 71% of tracts were designated consistently between USDA ERS and CDC. Our findings suggest a need for greater harmonization of these measures of community food access.

    2012-08-01

    Community coalitions have the potential to enhance a community's capacity to engage in effective problem solving for a range of community concerns. Although numerous studies have documented correlations between member engagement and coalition processes and structural characteristics, fewer have examined associations between coalition factors and community capacity outcomes. The current study uses data from an evaluation of the California Healthy Cities and Communities program to examine pathways between coalition factors (i.e. membership, processes), member engagement (i.e. participation, satisfaction) and community capacity as hypothesized by the Community Coalition Action Theory (CCAT). Surveys were completed by 231 members of 19 healthy cities and communities coalitions. Multilevel mediation analyses were used to examine possible mediating effects of member engagement on three community capacity indicators: new skills, sense of community and social capital. Results generally supported CCAT. Member engagement mediated the effects of leadership and staffing on community capacity outcomes. Results also showed that member engagement mediated several relationships between process variables (i.e. task focus, cohesion) and community capacity, but several unmediated direct effects were also observed. This suggests that although member engagement does explain some relationships, it alone is not sufficient to explain how coalition processes influence indicators of community capacity.

    Introduction Although partnerships between park and recreation agencies and health agencies are prevalent, little research has examined partnership characteristics and effectiveness among communities of different sizes. The objective of this study was to determine whether park and recreation leaders’ perceptions of partnership characteristics, effectiveness, and outcomes vary by community size. Methods A web-based survey was completed in 2007 by 1,217 National Recreation and Park Association members. Community size was divided into 4 categories: very small, small, medium, and large. Questions measured agencies’ recognition of the need for partnerships, their level of experience, and the effectiveness and outcomes of partnerships. Results Larger communities were significantly more likely to recognize the need for and have more experience with partnerships than smaller communities. Very small and large communities partnered significantly more often with senior services, nonprofit health promotion agencies, and public health agencies than did small and medium ones. Large and small communities were significantly more likely than very small and medium communities to agree that their decision making in partnerships is inclusive and that they have clearly defined goals and objectives. Large communities were significantly more likely than very small communities to report that their partnership helped leverage resources, make policy changes, meet their mission statement, and link to funding opportunities. Conclusion Community size shapes partnership practices, effectiveness, and outcomes. Very small communities are disadvantaged in developing and managing health partnerships. Increasing education, training, and funding opportunities for small and rural park and recreation agencies may enable them to more effectively partner with organizations to address community health concerns.

    Background Novel efforts and accompanying tools are needed to tackle the global burden of chronic disease. This paper presents an approach to describe the environments in which people live, work, and play. Community Health Environment Scan Survey (CHESS) is an empirical assessment tool that measures the availability and accessibility, of healthy lifestyle options lifestyle options. CHESS reveals existing community assets as well as opportunities for change, shaping community intervention planning efforts by focusing on community-relevant opportunities to address the three key risk factors for chronic disease (i.e. unhealthy diet, physical inactivity, and tobacco use). Methods The CHESS tool was developed following a review of existing auditing tools and in consultation with experts. It is based on the social-ecological model and is adaptable to diverse settings in developed and developing countries throughout the world. Results For illustrative purposes, baseline results from the Community Interventions for Health (CIH) Mexico site are used, where the CHESS tool assessed 583 food stores and 168 restaurants. Comparisons between individual-level survey data from schools and community-level CHESS data are made to demonstrate the utility of the tool in strategically guiding intervention activities. Conclusion The environments where people live, work, and play are key factors in determining their diet, levels of physical activity, and tobacco use. CHESS is the first tool of its kind that systematically and simultaneously examines how built environments encourage/discourage healthy eating, physical activity, and tobacco use. CHESS can help to design community interventions to prevent chronic disease and guide healthy urban planning. PMID:21394246

    Research has shown that the current practice of pharmacy staff when providing self-medication consultations in Indonesia is suboptimal. To improve the performance of pharmacy staff when providing self-medication consultations in community pharmacies, the factors that influence current practice need to be understood. The aim of this study is to identify the factors that influence current practice of pharmacy staff when handling self-medication consultations in Eastern Indonesian community pharmacies. Fifteen in-depth interviews were conducted with pharmacists, pharmacy technicians, pharmacy owners, and counter attendants. Thematic analysis was used to generate findings. The current practice of pharmacy staff when handling self-medication consultations is directly influenced by the professionalism of pharmacy staff and patient responses to the consultations. These factors are in turn affected by the organisational context of the pharmacy and the external pharmacy environment. The organisational context of the pharmacy includes staffing, staff affordability, and the availability of time and facilities in which to provide consultations. The external pharmacy environment includes the number of trained pharmacy staff in the research setting, the relevance of pharmacy education to the needs of pharmacy practice, the support offered by the Indonesian Pharmacists Association, a competitive business environment, and the policy environment. Complex and inter-related factors influence the current practice of pharmacy staff when providing self-medication consultations in community pharmacies in this research setting. Multiple strategies will be required to improve consultation practices.

    Green mould, resulting from Penicillium digitatum, is the most important postharvest disease of citrus. In a previous study, the PdSte12 transcription factor gene was identified, and disruption mutants were obtained. In the present study, the ΔPdSte12 mutants generated through gene replacement showed significantly reduced virulence during citrus fruit infection. Virulence was affected not only in mature fruit but also in immature fruit, and disease severity was markedly reduced when the oranges were stored at 20 or 4°C. In addition, the ΔPdSte12 mutants were defective in asexual reproduction, producing few conidia. The conidiophores of these mutants had longer metulae with fewer branches at the tip of the hyphae. Gene expression analysis revealed that PdSte12 might act as a negative regulator of several transporter-encoding genes and a positive regulator of two sterol demethylases, all of which are involved in fungicide resistance and fungal virulence. Moreover, PdSte12 exhibited the negative regulation of another transcription factor PdMut3, putatively involved in fungal pathogenesis but with no effect on the MAPK SLT2 P. digitatum orthologue belonging to different transcription pathways relevant to cell integrity. These results indicate the PdSte12 transcription factor is functionally conserved in P. digitatum for infection and asexual reproduction, similar to other Ste12 fungal plant pathogens.

    A study into the relevance of cultural factors in predicting condom-use intentions among Antillean migrants in the Netherlands is described in this article. The association between the intention to use condoms with a new sexual partner and a perceived taboo on discussing sex, beliefs about sex education and machismo beliefs on gender and power relationships is addressed. The study was conducted among 346 Dutch Antilleans from a random sample of an Antillean population aged 15-50 years. The response rate was 37.8%. The results showed that condom-use intentions were primarily determined by perceived subjective norms, the perceived taboo on discussing sex, machismo attitudes, gender, age and educational background. Moreover, the respondent's opinion regarding machismo was an effect modificator for the association between condom-use intentions and subjective social norm. It is concluded that, in predicting condom-use intentions, factors specific to the culture of a population contribute significantly to the determinants drawn from the general social-cognition models. It is recommended that future research should use measurement instruments that are adapted to culture-specific beliefs, and should explore the influence of cultural factors on actual condom use. Moreover, interventions promoting condom use among migrant populations should target the cultural correlates of condom use.

    To address a desire for timely, medically accurate cancer education in rural Alaska, ten culturally relevant online learning modules were developed with, and for, Alaska's Community Health Aides/Practitioners (CHA/Ps). The project was guided by the framework of Community-Based Participatory Action Research, honored Indigenous Ways of Knowing, and was informed by Empowerment Theory. A total of 428 end-of-module evaluation surveys were completed by 89 unique Alaska CHA/Ps between January and December 2016. CHA/Ps shared that as a result of completing the modules, they were empowered to share cancer information with their patients, families, friends, and communities, as well as engage in cancer risk reduction behaviors such as eating healthier, getting cancer screenings, exercising more, and quitting tobacco. CHA/Ps also reported the modules were informative and respectful of their diverse cultures. These results from end-of-module evaluation surveys suggest that the collaboratively developed, culturally relevant, online cancer education modules have empowered CHA/Ps to reduce cancer risk and disseminate cancer information.

    2014-01-01

    OBJECTIVES: This study explored multidimensional factors related to obesity by dividing them into individual and environmental factors, and performed multilevel analysis to investigate community environmental effects. METHODS: Data from the 2011 and 2012 Community Health Surveys were used for the analysis. Community-level variables, constructed from various regional statistics, were included in the model as environmental factors. Respondents with body mass index (BMI)≥25 were defined as obese, and a multilevel logistic regression analysis was conducted to analyze individual and environmental factors related to obesity. Moreover, a stratified analysis was conducted to compare factors related to obesity between men and women. RESULTS: Of 337,136 samples, 82,887 (24.6%) were obese, with BMI≥25. Sociodemographic characteristics at the individual level were mostly significantly related to obesity; however, while there were more obese men subjects among those with high socioeconomic status, there were more obese women among those with low socioeconomic status. There were fewer obese respondents among those who regularly walked and more obese respondents among those who reported short sleep duration or were highly stressed. At the community level, people living in areas with high socioeconomic status, high satisfaction with safety and public transportation, and high accessibility to sports facilities in their community had lower obesity risks. CONCLUSIONS: Community-level environmental factors affected obesity, especially perceived community environment, more significant than physical environment. Thus, it is necessary to develop effective obesity prevention and management strategies by considering potential community environmental factors that affect obesity. PMID:25666167

    Stakeholders in rural and mid-size urban communities were asked to share their views concerning factors that affect the mental health of older adults, and indicate how, and how well, these factors were addressed in their community. The identified factors clustered into six categories: clinical, physical, organizational, educational, psychosocial, and spiritual. Additional factors impacting care providers and caregivers and their ability to support the mental health of older adults also emerged. Similarities and distinct differences between rural and urban communities were reported and call for innovative strategies to meet the needs of seniors, particularly those living in rural areas.

    Community coalitions have the potential to enhance a community’s capacity to engage in effective problem solving for a range of community concerns. Although numerous studies have documented correlations between member engagement and coalition processes and structural characteristics, fewer have examined associations between coalition factors and community capacity outcomes. The current study uses data from an evaluation of the California Healthy Cities and Communities program to examine pathways between coalition factors (i.e. membership, processes), member engagement (i.e. participation, satisfaction) and community capacity as hypothesized by the Community Coalition Action Theory (CCAT). Surveys were completed by 231 members of 19 healthy cities and communities coalitions. Multilevel mediation analyses were used to examine possible mediating effects of member engagement on three community capacity indicators: new skills, sense of community and social capital. Results generally supported CCAT. Member engagement mediated the effects of leadership and staffing on community capacity outcomes. Results also showed that member engagement mediated several relationships between process variables (i.e. task focus, cohesion) and community capacity, but several unmediated direct effects were also observed. This suggests that although member engagement does explain some relationships, it alone is not sufficient to explain how coalition processes influence indicators of community capacity. PMID:21911845

    Toxic polycyclic aromatic hydrocarbons (PAHs) are frequently released into the environment from anthropogenic sources. PAH remediation strategies focus on biological processes mediated by bacteria. The availability of oxygen in polluted environments is often limited or absent, and only bacteria able to thrive in these conditions can be considered for bioremediation strategies. To identify bacterial strains able to degrade PAHs under oxygen-limiting conditions, we set up enrichment cultures from samples of an oil-polluted aquifer, using either anoxic or microaerophilic condition and with PAHs as the sole carbon source. Despite the presence of a significant community of nitrate-reducing bacteria, the initial community, which was dominated by Betaproteobacteria, was incapable of PAH degradation under strict anoxic conditions, although a clear shift in the structure of the community towards an increase in the Alphaproteobacteria (Sphingomonadaceae), Actinobacteria and an uncultured group of Acidobacteria was observed in the enrichments. In contrast, growth under microaerophilic conditions with naphthalene as the carbon source evidenced the development of a biofilm structure around the naphthalene crystal. The enrichment process selected two co-dominant groups which finally reached 97% of the bacterial communities: Variovorax spp. (54%, Betaproteobacteria) and Starkeya spp. (43%, Xanthobacteraceae). The two dominant populations were able to grow with naphthalene, although only Starkeya was able to reproduce the biofilm structure around the naphthalene crystal. The pathway for naphthalene degradation was identified, which included as essential steps dioxygenases with high affinity for oxygen, showing 99% identity with Xanthobacter polyaromaticivorans dbd cluster for PAH degradation. Our results suggest that the biofilm formation capacity of Starkeya provided a structure to allocate its cells at an appropriate distance from the toxic carbon source. © 2017 The Authors

    Antibiotics and antibacterials are present in water bodies worldwide but little is known about their effects on the biological processes often used to treat water. In this research, the effect of antibiotics on bacterial activity and community structure was investigated by growing biofilms in the presence and absence of a mixture of three compounds (sulfamethoxazole, erythromycin, and ciprofloxacin) in a continuous-flow rotating annular bioreactor fed acetate as a carbon and energy source. Steady-state, surface area-normalized substrate utilization rates for all antibiotic treatments (all at 0.33 μg L(-1), all at 3.33 μg L(-1), and 1 at 3.33 μg L(-1) with the other 2 at 0.33 μg L(-1)) were similar to the control experiments. Higher attached biomass levels in the experiments with ciprofloxacin at 3.33 μg L(-1) resulted in lower steady-state biomass-normalized substrate utilization rates in comparison to other runs. Microbial community analyses via automated ribosomal intergenic spacer analysis revealed significant shifts in community structure for the experiments dosed with the highest concentrations of ciprofloxacin, suggesting that the antibiotic selected for more resistant bacterial strains. The results of this research also suggest that mixtures of antibiotics at the sub-μg L(-1) concentrations typically observed in surface waters are unlikely to affect biological process performance, at least in terms of the degradation of easily assimilable compounds. Conversely, changes to community structure and biofilm quantity might be expected with ciprofloxacin at μg L(-1) concentrations. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Beneficial effects of intracerebral transplantation of mesenchymal stromal cells (MSC) and their derivatives are believed to be mediated mostly by factors produced by engrafted cells. However, the mesenchymal cell engraftment rate is low, and the majority of grafted cells disappear within a short post-transplantation period. Here, we hypothesize that dying transplanted cells can affect surrounding tissues by releasing their active intracellular components. To elucidate the type, amounts, and potency of these putative intracellular factors, freeze/thaw extracts of MSC or their derivatives were tested in enzyme-linked immunosorbent assays and bioassays. We found that fibroblast growth factor (FGF)2 and FGF1, but not vascular endothelial growth factor and monocyte chemoattractant protein 1 levels were high in extracts despite being low in conditioned media. Extracts induced concentration-dependent proliferation of rat cortical neural progenitor cells and human umbilical vein endothelial cells; these proliferative responses were specifically blocked by FGF2-neutralizing antibody. In the neuropoiesis assay with rat cortical cells, both MSC extracts and killed cells induced expression of nestin, but not astrocyte differentiation. However, suspensions of killed cells strongly potentiated the astrogenic effects of live MSC. In transplantation-relevant MSC injury models (peripheral blood cell-mediated cytotoxicity and high cell density plating), MSC death coincided with the release of intracellular FGF2. The data showed that MSC contain a major depot of active FGF2 that is released upon cell injury and is capable of acutely stimulating neuropoiesis and angiogenesis. We therefore propose that both dying and surviving grafted MSC contribute to tissue regeneration. PMID:25873141

    Public investment in community health centres (CHCs) has been increasing as a response to rapid urbanisation in China. The objectives of this study were: (1) to examine factors associated with CHC use among residents from a recently urbanised community in western China and (2) to describe satisfaction with CHC among users. Cross-sectional design. A community recently converted to urban status with a newly constructed CHC in Southwest China. A random sample of 2259 adults in the Hezuo community in Chengdu, China, completed the survey in 2013. Trained staff interviewed study participants in their homes using structured questionnaires. The survey included questions regarding sociodemographics, health status, access to and usage of healthcare, health behaviours and CHC use. The Andersen's behavioural model of health service use was used to guide multivariable logistic regression modelling in identifying predisposing, enabling and need factors associated with the likelihood of using CHC. Descriptive statistics were used to describe residents' satisfaction with the CHC. A total of 71.8% of the respondents reported using the CHC during the past year. Factors influencing adults' CHC use included: gender, marital status, education level and knowledge of one's blood pressure (predisposing factors); annual household per capita income and walking time to the CHC (enabling factors) and self-rated health as well as physical activities (need factors). CHC users reported modest satisfaction across various aspects of the CHC. Neighbourhood CHC in urban areas provides important services to these residents living in a recently urbanised community. All three categories of factors in the Andersen model help explain the likelihood of CHC use. There is much room for improvement in CHC to enhance customer satisfaction. Future research is needed to improve access to CHCs and promote their use in urbanised populations with low to modest education. © Article author(s) (or their employer

    Background Healthcare utilization has particular relevance as a public health and development issue. Unlike material and human capital, there is little empirical evidence on the utility of social resources in overcoming barriers to healthcare utilization in a developing country context. We sought to assess the relevance of social resources in overcoming barriers to healthcare utilization. Study Objective To explore community perceptions among three different wealth categories on factors influencing healthcare utilization in Eastern Uganda. Methods We used a qualitative study design using Focus Group Discussions (FGD) to conduct the study. Community meetings were initially held to identify FGD participants in the different wealth categories, ('least poor', 'medium' and 'poorest') using poverty ranking based on ownership of assets and income sources. Nine FGDs from three homogenous wealth categories were conducted. Data from the FGDs was analyzed using content analysis revealing common barriers as well as facilitating factors for healthcare service utilization by wealth categories. The Health Access Livelihood Framework was used to examine and interpret the findings. Results Barriers to healthcare utilization exist for all the wealth categories along three different axes including: the health seeking process; health services delivery; and the ownership of livelihood assets. Income source, transport ownership, and health literacy were reported as centrally useful in overcoming some barriers to healthcare utilization for the 'least poor' and 'poor' wealth categories. The 'poorest' wealth category was keen to utilize free public health services. Conversely, there are perceptions that public health facilities were perceived to offer low quality care with chronic gaps such as shortages of essential supplies. In addition to individual material resources and the availability of free public healthcare services, social resources are perceived as important in overcoming

    Non-negative matrix factorization (NMF) is a relatively new approach to analyze gene expression data that models data by additive combinations of non-negative basis vectors (metagenes). The non-negativity constraint makes sense biologically as genes may either be expressed or not, but never show negative expression. We applied NMF to five different microarray data sets. We estimated the appropriate number metagens by comparing the residual error of NMF reconstruction of data to that of NMF reconstruction of permutated data, thus finding when a given solution contained more information than noise. This analysis also revealed that NMF could not factorize one of the data sets in a meaningful way. We used GO categories and pre defined gene sets to evaluate the biological significance of the obtained metagenes. By analyses of metagenes specific for the same GO-categories we could show that individual metagenes activated different aspects of the same biological processes. Several of the obtained metagenes correlated with tumor subtypes and tumors with characteristic chromosomal translocations, indicating that metagenes may correspond to specific disease entities. Hence, NMF extracts biological relevant structures of microarray expression data and may thus contribute to a deeper understanding of tumor behavior.

    We determined factors that affect responses of bacterial isolates and model bacterial communities to the 95 carbon substrates in Biolog microliter plates. For isolates and communities of three to six bacterial strains, substrate oxidation rates were typically nonlinear and were delayed by dilution of the inoculum. When inoculum density was controlled, patterns of positive and negative responses exhibited by microbial communities to each of the carbon sources were reproducible. Rates and extents of substrate oxidation by the communities were also reproducible but were not simply the sum of those exhibited by community members when tested separately. Replicates of the same model community clustered when analyzed by principal- components analysis (PCA), and model communities with different compositions were clearly separated un the first PCA axis, which accounted for >60% of the dataset variation. PCA discrimination among different model communities depended on the extent to which specific substrates were oxidized. However, the substrates interpreted by PCA to be most significant in distinguishing the communities changed with reading time, reflecting the nonlinearity of substrate oxidation rates. Although whole-community substrate utilization profiles were reproducible signatures for a given community, the extent of oxidation of specific substrates and the numbers or activities of microorganisms using those substrates in a given community were not correlated. Replicate soil samples varied significantly in the rate and extent of oxidation of seven tested substrates, suggesting microscale heterogeneity in composition of the soil microbial community.

    Objective The Communities That Care (CTC) prevention system seeks to build community capacity for a science-based approach to the promotion of healthy youth development. Prior research shows the positive effects of CTC on youth protective factors during CTC implementation. This research tests sustained effects of CTC on youth protective factors 1 year after external support to communities for CTC implementation ended. Method Data come from a community-randomized trial of CTC in 24 communities across 7 states. A panel of 4,407 youth in CTC and control communities was surveyed annually from Grade 5 through Grade 10. Youth reported their exposure to protective factors identified in the social development model. Global test statistics are calculated to examine effects of CTC across 15 protective factors in 5 domains (community, school, family, peer, and individual) assessed in Grade 10, 1 year after study support for CTC implementation ended. Analyses also examine variation in sustained effects by gender and baseline risk levels. Results Global effects of CTC on protective factors across all domains are not sustained in Grade 10. However, sustained domain-specific effects are observed in the individual domain for males, in the peer domain for females, and in the individual domain for youth with low-to-medium risk at baseline. Conclusions Greater emphasis on strengthening protective factors during high school might be needed to sustain broad effects of CTC on protective factors observed during middle school. PMID:26951879

    Soil microbial communities play important role in organic matter decomposition, nutrient cycling and vegetation dynamic. However, little is known about factors driving soil microbial community composition at large scales. The objective of this study was to determine whether climate dominates among environmental factors governing microbial community composition and biomass at a regional scale. Here, we compared soil microbial communities using phospholipid fatty acid method across 7 land use types from 23 locations in North-East China Transect (850 km x 50 km). The results showed that soil water availability and land use changes exhibited the dominant effects on soil microbial community composition and biomass at the regional scale, while climate factors (expressed as a function of large-scale spatial variation) did not show strong relationships with distribution of microbial community composition. Likewise, factors such as spatial structure, soil texture, nutrient availability and vegetation types were not important. Wetter soils had higher contributions of gram-positive bacteria, whereas drier soils had higher contributions of gram-negative bacteria and fungi. Heavily disturbed soils had lower contributions of gram-negative bacteria and fungi than historically disturbed and undisturbed soils. The lowest microbial biomass appeared in the wettest and driest soils. In conclusion, dominant climate factors, commonly known to structure distribution of macroorganisms, were not the most important drivers governing regional pattern of microbial communities because of inclusion of irrigated and managed practices. In comparison, soil water regime and land use types appear to be primary determinants of microbial community composition and biomass.

    There are disproportionately higher and inconsistently distributed rates of recorded suicides in rural areas. Patterns of rural suicide are well documented, but they remain poorly understood. Geographic variations in physical and mental health can be understood through the combination of compositional, contextual, and collective factors pertaining to particular places. The aim of this study was to explore the role of "place" contributing to suicide rates in rural communities. Seventeen mental health professionals participated in semi-structured in-depth interviews. Principles of grounded theory were used to guide the analysis. Compositional themes were demographics and perceived mental health issues; contextual themes were physical environment, employment, housing, and mental health services; and collective themes were town identity, community values, social cohesion, perceptions of safety, and attitudes to mental illness. It is proposed that connectedness may be the underlying mechanism by which compositional, contextual, and collective factors influence mental health and well-being in rural communities.

    2016-01-01

    Little is known about the relative importance of spatial and environmental factors to structuring aquatic and sedimentary microbial biogeography in lakes. Here, we investigated the microbial community composition (MCC) of the water (n = 35) and sediment (n = 35) samples from 16 lakes in western China (salinity: freshwater to salt saturation; pairwise geographical distance: 9–2027 km) using high-throughput sequencing and evaluated the relative importance of spatial and environmental factors to microbial (including total, abundant, and rare) distributions. Our results showed that spatial factors were more important than environmental factors in shaping the biogeography of aquatic and sedimentary microbial communities in the studied lakes, and spatial factors on abundant microbial community was stronger than that on the total/rare microbial communities. Moreover, sedimentary rare MCC might be more sensitive to environmental factors than its aquatic counterpart. Such different biogeography responses of total, abundant, and rare communities to environmental and spatial factors could be ascribed to different physiochemical properties between water and sediment. Collectively, this study expands our understanding of factors shaping microbial biogeography of total, abundant, and rare communities between waters and sediments of lakes. PMID:27877171

    This study examined the practices, personal motivation, and barriers of African American communities in Mississippi regarding their dietary practices. We selected the Metro Jackson Area comprised of Hinds, Madison and Rankin Counties because it is a combination of urban and rural communities. The sample consisted of 70 participants from seven sites. A total of seven focus groups responded to six questions to assess practices, personal motivation, and barriers to dietary practices: (1) Where in your community can you access fresh fruits and vegetables? (2) How many meals a day should a person eat? (3) What would you consider to be a healthy breakfast, lunch and dinner? (4) What would you consider to be a healthy snack? (5) What do you consider to be your motivations for eating healthy? (6) What do you consider to be your barriers to eating healthy? Each of the seven focus groups consisted of 6 to 12 participants and provided details of their dietary practices. The focus group interviews were digitally-recorded. The recorded interviews were transcribed. The majority of the participants stated that there is a limited availability of fresh fruits/vegetables in rural areas because of a shortage of grocery stores. When they do find fruits, they are priced very high and are unaffordable. Even though health conditions dictate food frequency and portion size, community members feel that individuals should eat three good balanced meals per day with snacks, and they should adhere to small portion sizes. While the desire to attain overall good health and eliminate associative risks for heart disease (e.g., diabetes, obesity) are personal motivations, the cost of food, transportation, age, and time required for food preparation were seen as barriers to healthy eating. Decisions regarding meal choice and meal frequency can have an impact on long-term health outcomes. Health promotion programs should become an integral part of academic- community collaborative agreements. PMID

    Introduction The prognostic significance of disseminated tumor cells in the bone marrow (DTC-BM) of breast cancer patients has been demonstrated in many studies. Yet, it is not clear which of the primary tumors' biological factors predict hematogenous dissemination. We therefore examined 'tissue micro arrays' (TMAs) of 265 primary breast carcinomas from patients with known bone marrow (BM) status for HER2, Topoisomerase IIα (Top IIa), Ki 67, and p53. Methods BM analysis was performed by cytospin preparation and immunocytochemical staining for cytokeratin (CK). TMAs were examined by immunohistochemistry (IHC) for HER2, Top IIa, Ki 67 and p53, and fluorescence in situ hybridization (FISH) for HER2. Results HER2 (2+/3+) was positive in 35/167 (21%) cases (FISH 24.3%), Top IIa (>10%) in 87/187 (46%), Ki 67 in 52/184 (28%) and p53 (>5%) in 61/174 cases (34%). Of 265 patients, 68 (25.7%) showed DTC-BM with a median of 2/2 × 106 cells (1 to 1,500). None of the examined factors significantly predicted BM positivity. Significant correlation was seen between HER2 IHC and Top IIa (p = 0.06), Ki 67 (p = 0.031), and p53 (p < .001). Top IIa correlated with Ki 67 and p53, and Ki 67 also with p53 (p = 0.004). After a median follow-up of 60.5 months (7 to 255), the presence of DTC-BM showed prognostic relevance for overall survival (p = 0.03), whereas HER2 (IHC, p = 0.04; FISH, p = 0.03) and Ki 67 (p = 0.04) correlated with disease free survival, and HER2 with distant disease free survival (IHC, p = 0.06; FISH, p = 0.05). Discussion The congruence of the examined factors' expression rates indicates a causal line of suppressor, proliferation, and mitosis markers, and growth factor receptors. Hematogenous tumor cell spread seems to be an independent process. The examination of these factors on DTC-BM is the aim of ongoing research. PMID:16457698

  6. Emission of climate-relevant trace gases and succession of microbial communities during open-windrow composting

    1997-03-01

    Municipal solid-waste composting is a process of increasing importance, based primarily on augmentation of microbial activity. The composting of organic matter leads not only to a reduction in waste but a sensible recycling of residuals to their origin. Carbon dioxide derived from plant matter degradation does not contribute to global warming. However, emitted nitrous oxide and methane molecules contribute to the enhancement of the greenhouse effect. This study determined a wide variety of microbial properties during the composting processes at a whole windrow level and quantified the emission rates of the climate relevant trace gases, carbon dioxide, nitrous oxide and methane during the course of maturation of a compost row. 47 refs., 6 figs., 1 tab.

    Three species of yews Taxus contorta Griff., Taxus mairei (Lemée & Lév.) S.Y. Hu ex T.S. Liu and Taxus wallichiana Zucc. distributed in the Hindu Kush-Himalayan (HKH) region have been commercially exploited in recent decades to extract an anticancer chemotherapeutic drug 'Taxol'. Additionally, indigenous people of this region are using yews for several other purposes including gastro-intestinal disorders, respiratory problems, skeletal system disorders, and as edible fruit, fodder, fish poison, traditional veterinary medicine, among others. The study was designed to document and evaluate knowledge concerning uses of yews among indigenous communities of Mongol and Caucasian origins. Ethnobotanical knowledge from 10 major ethnic/caste groups of Mongol and Caucasian origins in the Nepal Himalayas was documented in 2010 and 2011 from 27 sites covering the extant distribution range of the three species of Taxus. A total of 72 key informants (60 men, 12 women), recommended by the majority of people in informal group discussions at each study site, were interviewed to collect information on the importance of yews. This study reports multidimensional uses of yews commonly practiced by different indigenous communities of Nepal and compared those with published uses along the HKH region. The key informants cited a total 45 uses under 21 categories. A greater use diversity and high consensus value for use types were recorded for medicinal uses (gastro-intestinal ailments, cough and cold, skeleto-muscular system problem and others medicinal importance) followed by fruit consumption, household tools, agriculture implements and timber. A decline of yew populations and associated traditional knowledge among the younger generations of indigenous people was found. The present study shows a strong agreement of ethnobotanical knowledge on yews between communities of Mongols and Caucasian origins. Our findings further revealed the potential for additional therapeutic applications in

    Community detection is important for understanding networks. Previous studies observed that communities are not necessarily disjoint and might overlap. It is also agreed that some outlier vertices participate in no community, and some hubs in a community might take more important roles than others. Each of these facts has been independently addressed in previous work. But there is no algorithm, to our knowledge, that can identify these three structures altogether. To overcome this limitation, we propose a novel model where vertices are measured by their centrality in communities, and define the identification of overlapping communities, hubs, and outliers as an optimization problem, calculated by nonnegative matrix factorization. We test this method on various real networks, and compare it with several competing algorithms. The experimental results not only demonstrate its ability of identifying overlapping communities, hubs, and outliers, but also validate its superior performance in terms of clustering quality.

    To determine any differences in oral cancer risk factor awareness and behaviour among first and second generation Gujarati muslims and to investigate the impact of a community-based health education programme on oral cancer risk factor awareness. Respondents completed a confidential, bilingual questionnaire in English and Gujarati regarding alcohol, tobacco, paan, sopari, paan masala and gutka use before and after a community-based health education programme on oral cancer risk factors. Community Health Fair. Indian Muslim Welfare Association, Batley, West Yorkshire. Ninety-six male and female Gujarati muslims aged 16 to 81 years. Quantitative results on oral cancer risk factor awareness before and after a health education programme. Quantitative figures obtained from the questionnaire with regards to alcohol, tobacco, paan, sopari, paan masala and gutka usage. There were very low levels of alcohol consumption among Gujarati muslims. First generation Gujarati males consumed significantly more tobacco than second generation Gujarati males, difference in proportion 0.30 (0.03 to 0.56, p = 0.03). There was complete absence of paan use among Gujarati females. First generation Gujarati males consumed significantly higher amounts of sopari compared with their male counterparts in the second generation (p = 0.003). There were very low rates of paan masala use. Only first generation Gujarati males consumed gutka. Significantly more first generation males and females correctly identified all oral cancer risk factors after the health education intervention compared with baseline (difference 0.40, 95% CI 0.23 to 0.57, p = <0.001). Significantly more second generation males and females correctly identified all oral cancer risk factors after the health education intervention compared with baseline (difference 0.45, 95% CI 0.28 to 0.61, p = <0.001).

    A series of twenty-six interviews, fourteen with district nursing sisters and twelve with students they supervised, was conducted in 1992 in one Project 2000 demonstration district in England. The data were collected as part of an English National Board funded research study; data were reinterpreted in 1994 and formed one element in the author's PhD thesis. Participants described the ways in which a supervisor might enable a student to learn during a community placement. One of the most important means by which supervisors could provide assistance was by creating an environment in which the students felt supported. Students described how supervisors demonstrated concern, acceptance and understanding, attributes which bore striking resemblance to the qualities of congruence, unconditional positive regard and empathic understanding identified by Carl Rogers as enabling learning.

    This study investigated factors that contributed to the participation of a rural community in health education. It was conducted in the Awi zone of the Amhara region in Ethiopia. The participants were rural community members and health extension workers. Purposive and snowball sampling techniques were used to recruit rural community members, whereas convenient sampling was used to recruit health extension workers. Data was collected through in-depth individual interviews, and focus group discussions. The study revealed various factors contributing to the participation of a rural community in health education, including attainability of the objectives of health education, profiles of the health extension workers, peer influence, organization of the health education program in terms of place and time, and meaningfulness of the health education in terms of rural community lives. Although the ultimate goal of participation in health education is similar for all rural community members, they were attracted to the program by one or more than one different factor. Efforts aimed at enhancing participation of a rural community in health education program should address each factor that contributes to the participation of community members.

  19. Protective Factors for Youth Exposed to Violence in Their Communities: A Review of Family, School, and Community Moderators.

    PubMed

    Ozer, Emily J; Lavi, Iris; Douglas, Laura; Wolf, Jennifer Price

    2017-01-01

    This review provides a comprehensive investigation of the pattern and strength of findings in the literature regarding the environmental moderators of the relationship between exposure to community violence and mental health among children and adolescents. Twenty-nine studies met criteria for inclusion in our analysis of family, school, and community variables as moderators. Dependent variables included internalizing (e.g., anxiety, depression, posttraumatic stress disorder) and externalizing symptoms (e.g., aggression, substance use). Effect sizes for the interactions of exposure to violence and potential moderators were summarized by their patterns of protective processes. The majority of studies in the literature examined family characteristics as moderators of the exposure to violence-symptom relationship, rather than school- or community-level factors. Our results indicated more consistent patterns for (a) close family relationships and social support for internalizing symptoms and (b) close family relationships for externalizing symptoms. Overall, the most common type of protective pattern was protective-stabilizing, in which youth with higher levels of the environmental attribute demonstrate relative stability in mental health despite exposure to violence. We found no consistent evidence that parental monitoring-a dimension inversely associated with exposure to violence in prior studies-moderated the relationship between exposure to violence and symptoms. The study emphasizes the importance of strengthening family support for young people's exposure to community violence; more research is needed to provide a solid evidence base for the role of school and community-level protective factors for youth exposed to violence.

    Background: Plantar fasciitis (PF) is a common foot complaint, affects both active sportsmen and physically inactive middle age group. It is believed that PF results from degenerative changes rather than inflammation. Platelet-rich plasma (PRP) therapy has been introduced as an alternative therapy for PF. This study is aimed to systematically review to the effectiveness and relevant factors of PRP treatment in managing PF. Materials and Methods: A search was conducted in electronic databases, including PubMed, Scopus, and Google Scholar using different keywords. Publications in English-language from 2010 to 2015 were included. Two reviewers extracted data from selected articles after the quality assessment was done. Results: A total of 1126 articles were retrieved, but only 12 articles met inclusion and exclusion criteria. With a total of 455 patients, a number of potentially influencing factors on the effectiveness of PRP for PF was identified. In all these studies, PRP had been injected directly into the plantar fascia, with or without ultrasound guidance. Steps from preparation to injection were found equally crucial. Amount of collected blood, types of blood anti-coagulant, methods in preparing PRP, speed, and numbers of time the blood samples were centrifuged, activating agent added to the PRP and techniques of injection, were varied between different studies. Regardless of these variations, superiority of PRP treatment compared to steroid was reported in all studies. Conclusion: In conclusion, PRP therapy might provide an effective alternative to conservative management of PF with no obvious side effect or complication. The onset of action after PRP injection also greatly depended on the degree of degeneration. PMID:27904584

    IRF-1 and IRF-2 expression was determined by real-time PCR in 138 ovarian cancer samples and 30 healthy ovarian biopsies and was correlated with the expression of other relevant immunologic parameters and common clinicopathologic variables. Regulation of IRF-1 and IRF-2 was evaluated by cytokine treatment of various ovarian cancer cell lines, human peritoneal mesothelial cells and ovarian surface epithelium. IRF-1 but not IRF-2 was constitutively over-expressed in 5 of 7 ovarian cancer cell lines. Both IRFs were inducible with IFN-gamma and to a lesser extent with IL-1 or TNF-alpha, but not with IL-6. Epidermal growth factor (EGF) treatment down-regulated both IRFs. In ovarian cancer samples only IRF-1, but not IRF-2 mRNA, was up-regulated when compared with healthy ovarian tissue. IRF-1 but not IRF-2 expression was significantly associated with interferon (IFN)-gamma and forkhead box P3 (FoxP3). In univariate survival analysis, strong expression of IRF-1 and IRF-2 predicted improved disease-free survival (DFS) and overall survival (OS). In Cox regression analyses, IRF-1 retained independent prognostic significance for DFS and OS and IFN-gamma for OS. In contrast to other solid tumors, IRF-2 expression cannot be regarded as a classic oncoprotein associated with poor prognosis in ovarian cancer. Of the immunologic parameters investigated, intratumoral IRF-1 expression is the most powerful independent predictor of a favorable clinical outcome.

  2. Data quality and relevance in ecotoxicity: The undocumented influences of model assumptions and modifying factors on aquatic toxicity dose metrics.

    2015-11-01

    A model-based approach using hypothetical organic chemicals examines how aquatic toxicity test results are influenced by toxicity modifying factors such as hydrophobicity, exposure duration, body size, lipid content, mode of toxic action (via Critical Body Residue differences), and metabolic degradation. Differences of up to one to three orders of magnitude were identified for modeled LC50s. Dominance of CBR by low log Kow chemicals can cause further influences. Such differences cause significant changes in the relationship between exposure- and organism-based doses and create substantial difficulties for both interpretation of test results and extrapolation to other laboratory or field exposure conditions. The resulting variability is not readily evident in toxicity testing as insufficient data are collected to validate fundamental assumptions. Consequently, results obtained with standard aquatic toxicity test protocols do not yield consistent, comparable measures of relative toxicity and are inappropriate for quantitative toxicology and risk applications. The substantial uncertainties in testing results created by such undocumented variability must also be given serious consideration in data quality and relevance assessments. Necessary improvements in aquatic toxicity testing methodology should include explicit estimation of toxicokinetics and toxicodynamics and routine validation of toxicological model assumptions.

    Background The U.S. Agency for Healthcare Research and Quality (AHRQ) developed a hospital patient safety culture survey in 2004, and has adapted this survey to other healthcare settings, such as nursing homes and medical offices, and most recently community pharmacies. However, it is unknown if safety culture dimensions developed in hospital settings can be transferred to community pharmacies. The aim of this study was to assess the psychometric properties of the Community Pharmacy Survey on Patient Safety Culture. Method The survey was administered to 543 community pharmacists in [state], United States. Confirmatory factor analysis was used to assess the fit of our data with the proposed AHRQ model. Exploratory factor analysis was used to determine the underlying factor structure. Internal consistency reliabilities were calculated. Results A total of 433 usable surveys were returned (response rate of 80%). Results from the confirmatory factor analysis showed inadequate model fit for the original 36 item, 11-factor structure. Exploratory factor analysis showed that a modified 27 item, 4-factor structure better reflected the underlying safety culture dimensions in community pharmacies. The communication openness factor, with 3 items, dropped in its entirety while 6 items dropped from multiple factors. The remaining 27 items redistributed to form the 4-factor structure: safety related communication, staff training and work environment, organizational response to safety events, and staffing, work pressure and pace. Cronbach's α of 0.95 suggested good internal consistency. Conclusion Dimensions related to safety culture in a community pharmacy environment may differ from those in other healthcare settings such as in hospitals. Our findings suggest that validation studies need to be conducted before applying safety dimensions from other healthcare settings into community pharmacies. PMID:26208535

  5. Capacity factor analysis for evaluating water and sanitation infrastructure choices for developing communities.

    40% of the world's population lacks access to adequate supplies of water and sanitation services to sustain human health. In fact, more than 780 million people lack access to safe water supplies and about 2.5 billion people lack access to basic sanitation. Appropriate technology for water supply and sanitation (Watsan) systems is critical for sustained access to these services. Current approaches for the selection of Watsan technologies in developing communities have a high failure rate. It is estimated that 30%-60% of Watsan installed infrastructures in developing countries are not operating. Inappropriate technology is a common explanation for the high rate of failure of Watsan infrastructure, particularly in lower-income communities (Palaniappan et al., 2008). This paper presents the capacity factor analysis (CFA) model, for the assessment of a community's capacity to manage and sustain access to water supply and sanitation services. The CFA model is used for the assessment of a community's capacity to operate, and maintain a municipal sanitation service (MSS) such as, drinking water supply, wastewater and sewage treatment, and management of solid waste. The assessment of the community's capacity is based on seven capacity factors that have been identified as playing a key role in the sustainability of municipal sanitation services in developing communities (Louis, 2002). These capacity factors and their constituents are defined for each municipal sanitation service. Benchmarks and international standards for the constituents of the CFs are used to assess the capacity factors. The assessment of the community's capacity factors leads to determine the overall community capacity level (CCL) to manage a MSS. The CCL can then be used to assist the community in the selection of appropriate Watsan technologies for their MSS needs. The selection is done from Watsan technologies that require a capacity level to operate them that matches the assessed CCL of the

    Macrophage colony stimulating factor (M-CSF) is a cytokine that promotes monocyte differentiation and survival. When overexpressed, M-CSF contributes to pathology in a wide variety of diseases, including osteoporosis, obesity, certain human cancers, and in human immunodeficiency virus type 1 (HIV-1) infection, particularly with respect to monocyte/macrophage infection and the development of HIV-1 associated central nervous system disorders. In this study, our aim was to expand the current knowledge of M-CSF regulation, focusing on nuclear factor kappa B (NF-κB), a transcription factor playing a prominent role during inflammation and HIV-1 infection. Our results suggest that tumor necrosis factor alpha (TNF-α) promotes M-CSF secretion in primary macrophages and activates the -1310/+48 bp M-CSF promoter in Mono-Mac 1 cells. Inhibitors of the NF-κB pathway diminish this response. We identified four putative NF-κB and four CCAAT-enhancer-binding protein beta binding sites within the M-CSF promoter. Our findings, using promoter constructs mutated at individual NF-κB sites within the M-CSF promoter region, suggest that these sites are redundant with respect to NF-κB regulation. TNF-α treatment promoted NF-κB p65 binding to the M-CSF promoter in phorbol 12-myristate 13-acetate (PMA) treated U937 cells chronically infected with HIV-1 (U1 cells), but not in PMA treated uninfected U937 cells, suggesting that the presence of HIV-1 increases the NF-κB response. In conclusion, our findings demonstrate that NF-κB induces M-CSF expression on a promoter level via multiple functional NF-κB binding sites and that this pathway is likely relevant in HIV-1 infection of macrophages.

    Research into nursing home transitions has given limited attention to the facility or community contexts. To identify facility and market factors affecting transitions of nursing home residents back to the community. Multilevel models were used to estimate effects of facility and market factors on facility-level community discharge rates after controlling for resident demographic, health, and functional conditions. Facility discharge rates were adjusted using Empirical Bayes estimation. Annual cohort of first-time admissions (N=24,648) to 378 Minnesota nursing facilities in 75 nursing home markets from July 2005 to June 2006. Community discharge within 90 days of admission; facility occupancy, payer mix, ownership, case-mix acuity, size, admissions from hospitals, nurse staffing level, and proportion of admissions preferring or having support to return to the community; and nursing market population size, average occupancy, market concentration, and availability of home and community-based services. Rates of community discharge (Empirical Bayes residual) were highest in facilities with more residents preferring community discharge, more Medicare days, higher nurse staffing levels, and higher occupancy. In addition, facilities had higher community discharge rates if they were located in markets with a greater ratio of home and community-based services recipients to nursing home residents and with larger populations. State Medicaid programs should undertake system-level interventions that encourage nursing facilities to reduce unused bed capacity, balance the mix of payers, invest in nurse staffing, and take other steps to promote community discharges. In addition, states should increase home and community-based services, particularly in markets with low community discharge rates.

    While short-term plant responses to global change are driven by physiological mechanisms, which are represented relatively well by models, long-term ecosystem responses to global change may be determined by shifts in plant community structure resulting from other ecological phenomena such as interspecific interactions, which are represented poorly by models. In single-factor scenarios, plant communities often adjust to increase ecosystem response to that factor. For instance, some early global change experiments showed that elevated CO2 favours plants that respond strongly to elevated CO2, generally amplifying the response of ecosystem productivity to elevated CO2, a positive community feedback. However, most ecosystems are subject to multiple drivers of change, which can complicate the community feedback effect in ways that are more difficult to generalize. Recent studies have shown that (i) shifts in plant community structure cannot be reliably predicted from short-term plant physiological response to global change and (ii) that the ecosystem response to multi-factored change is commonly less than the sum of its parts. Here, we survey results from long-term field manipulations to examine the role community shifts may play in explaining these common findings. We use a simple model to examine the potential importance of community shifts in governing ecosystem response. Empirical evidence and the model demonstrate that with multi-factored change, the ecosystem response depends on community feedbacks, and that the magnitude of ecosystem response will depend on the relationship between plant response to one factor and plant response to another factor. Tradeoffs in the ability of plants to respond positively to, or to tolerate, different global change drivers may underlie generalizable patterns of covariance in responses to different drivers of change across plant taxa. Mechanistic understanding of these patterns will help predict the community feedbacks that determine

  10. Gas-phase organics in environmental tobacco smoke: 2. Exposure-relevant emission factors and indirect exposures from habitual smoking

    NASA Astrophysics Data System (ADS)

    Singer, Brett C.; Hodgson, Alfred T.; Nazaroff, William W.

    Sorption of emitted gas-phase organic compounds onto material surfaces affects environmental tobacco smoke (ETS) composition and exposures indoors. We have introduced a new metric, the exposure relevant emission factor (EREF) that accounts for sorptive uptake and reemission to give the mass of individual ETS constituents available for exposure over a day in which smoking occurs. This paper describes month-long experiments to investigate sorption effects on EREFs and potential ETS exposures under habitual smoking conditions. Cigarettes were smoked in a 50-m 3 furnished room over a 3-h period 6-7 days per week, with continuous ventilation at 0.3, 0.6, or 2.1 h -1. Organic gas concentrations were measured every few days over 4-h "smoking", 10-h "post-smoking" and 10-h "background" periods. Concentration patterns of volatile ETS components including 1,3-butadiene, benzene and acrolein were similar to those calculated for a theoretical non-sorbing tracer, indicating limited sorption. Concentrations of ETS tracers, e.g. 3-ethenylpyridine (3-EP) and nicotine, and lower volatility toxic air contaminants including phenol, cresols, and naphthalene increased as experiments progressed, indicating mass accumulation on surfaces and higher desorption rates. Daily patterns stabilized after week 2, yielding a steady daily cycle of ETS concentrations associated with habitual smoking. EREFs for sorbing compounds were higher under steady cycle versus single-day smoking conditions by ˜50% for 3-EP, and by 2-3 times for nicotine, phenol, cresols, naphthalene, and methylnaphthalenes. Our results provide relevant information about potential indirect exposures from residual ETS (non-smoker enters room shortly after smoker finishes) and from reemission, and their importance relative to direct exposures (non-smoker present during smoking). Under the conditions examined, indirect exposures accounted for a larger fraction of total potential exposures for sorbing versus non-sorbing compounds

    The present paper examines the relationship between hydrochemical characteristics and endemic dental fluorosis, controlling for variables with information on an individual level. An epidemiological survey was carried out in seven rural communities in two municipalities in the state of Minas Gerais, Brazil. The Thystrup & Fejerskov index was employed by a single examiner for the diagnosis of dental fluorosis. A sampling campaign of deep groundwater in the rural communities of interest was carried out concomitantly to the epidemiological survey for the determination of physiochemical parameters. Multilevel modeling of 276 individuals from seven rural communities was achieved using the non-linear logit link function. Parameters were estimated using the restricted maximum likelihood method. Analysis was carried out considering two response variables: presence (TF 1 to 9) or absence (TF = 0) of any degree of dental fluorosis; and presence (TF ≥ 5-with loss of enamel structure) or absence of severe dental fluorosis (TF ≤ 4-with no loss of enamel structure). Hydrogeological analyses revealed that dental fluorosis is influenced by the concentration of fluoride (OR = 2.59 CI95% 1.07-6.27; p = 0.073) and bicarbonate (OR = 1.02 CI95% 1.01-1.03; p = 0.060) in the water of deep wells. No other variable was associated with this prevalence (p > 0.05). More severe dental fluorosis (TF ≥ 5) was only associated with age group (p < 0.05). No other variable was associated to the severe dental fluorosis (p > 0.05). Dental fluorosis was found to be highly prevalent and severe. A chemical element besides fluoride was found to be associated (p > 0.05) to the prevalence of dental fluorosis, although this last finding should be interpreted with caution due to its p value.

    To evaluate the factor structure of the revised Partners in Health (PIH) scale for measuring chronic condition self-management in a representative sample from the Australian community. A series of consultations between clinical groups underpinned the revision of the PIH. The factors in the revised instrument were proposed to be: knowledge of illness and treatment, patient-health professional partnership, recognition and management of symptoms and coping with chronic illness. Participants (N = 904) reporting having a chronic illness completed the revised 12-item scale. Two a priori models, the 4-factor and bi-factor models were then evaluated using Bayesian confirmatory factor analysis (BCFA). Final model selection was established on model complexity, posterior predictive p values and deviance information criterion. Both 4-factor and bi-factor BCFA models with small informative priors for cross-loadings provided an acceptable fit with the data. The 4-factor model was shown to provide a better and more parsimonious fit with the observed data in terms of substantive theory. McDonald's omega coefficients indicated that the reliability of subscale raw scores was mostly in the acceptable range. The findings showed that the PIH scale is a relevant and structurally valid instrument for measuring chronic condition self-management in an Australian community. The PIH scale may help health professionals to introduce the concept of self-management to their patients and provide assessment of areas of self-management. A limitation is the narrow range of validated PIH measurement properties to date. Further research is needed to evaluate other important properties such as test-retest reliability, responsiveness over time and content validity.

    The purpose of this article is to critically discuss issues that pertain to the operationalization of community participation in community-based rehabilitation (CBR). Data were drawn from an international, questionnaire-based survey of occupational therapists involved in CBR conducted through the World Federation of Occupational Therapists. A search of CINAHL. PsychInfo and Medline databases for articles on CBR was performed and both descriptive articles and analytical ones were included. Although there are guidelines on the nature of CBR these do not always match its application in practice. Active involvement of local communities in CBR projects is often limited, threatening the sustainability of CBR programmes. Furthermore, the failure to acknowledge the sociopolitical underpinnings and the cultural nature of disability is likely to compromise the nature of disabled people's involvement in CBR. There is confusion and lack of clarity about the nature of CBR. Educational modules on CBR should be made available to professionals. These should consider the importance of community involvement and context-specific and culture-sensitive programmes in practice.

  16. Soil Microbial Community Responses to Long-Term Global Change Factors in a California Grassland

    Soil fungal and bacterial communities act as mediators of terrestrial carbon and nutrient cycling, and interact with the aboveground plant community as both pathogens and mutualists. However, these soil microbial communities are sensitive to changes in their environment. A better understanding of the response of soil microbial communities to global change may help to predict future soil microbial diversity, and assist in creating more comprehensive models of terrestrial carbon and nutrient cycles. This study examines the effects of four global change factors (increased temperature, increased variability in precipitation, nitrogen deposition, and CO2 enrichment) on soil microbial communities at the Jasper Ridge Global Change Experiment (JRGCE), a full-factorial global change manipulative experiment on three hectares of California grassland. While similar studies have examined the effects of global change on soil microbial communities, few have manipulated more factors or been longer in duration than the JRGCE, which began field treatments in 1998. We find that nitrogen deposition, CO2 enrichment, and increased variability in precipitation significantly affect the structure of both fungal and bacterial communities, and explain more of the variation in the community structures than do local soil chemistry or aboveground plant community. Fungal richness is correlated positively with soil nitrogen content and negatively with soil water content. Arbuscular mycorrhizal fungi (AMF), which associate closely with herbaceous plants' roots and assist in nutrient uptake, decrease in both richness and relative abundance in elevated CO2 treatments.

    Community health workers (CHWs) are increasingly recognized as an integral component of the health workforce needed to achieve public health goals in low- and middle-income countries (LMICs). Many factors influence CHW performance. A systematic review was conducted to identify intervention design related factors influencing performance of CHWs. We systematically searched six databases for quantitative and qualitative studies that included CHWs working in promotional, preventive or curative primary health services in LMICs. One hundred and forty studies met the inclusion criteria, were quality assessed and double read to extract data relevant to the design of CHW programmes. A preliminary framework containing factors influencing CHW performance and characteristics of CHW performance (such as motivation and competencies) guided the literature search and review. A mix of financial and non-financial incentives, predictable for the CHWs, was found to be an effective strategy to enhance performance, especially of those CHWs with multiple tasks. Performance-based financial incentives sometimes resulted in neglect of unpaid tasks. Intervention designs which involved frequent supervision and continuous training led to better CHW performance in certain settings. Supervision and training were often mentioned as facilitating factors, but few studies tested which approach worked best or how these were best implemented. Embedment of CHWs in community and health systems was found to diminish workload and increase CHW credibility. Clearly defined CHW roles and introduction of clear processes for communication among different levels of the health system could strengthen CHW performance.

    To reach insurance physician (IPs) consensus on factors that must be taken into account in the assessment of the work ability of employees who are sick-listed for 2 years. A Delphi study using online questionnaires was conducted from October 2010 to March 2011. One hundred and two insurance physicians reached a consensus on important factors for return to work (RTW) of employees on long-term sick leave; from those factors, the most relevant for the assessment of work ability was determined. From a total of 22 relevant factors considered for the return to work of long-term sick-listed employees, consensus was reached on nine relevant factors that need to be taken into account in the assessment of the work ability of employees on long-term sick leave. Relevant factors that support return to work are motivation, attitude towards RTW, assessment of cognitions and behaviour, vocational rehabilitation in an early stage and instruction for the sick-listed employee to cope with his disabilities. Relevant factors that hinder RTW are secondary gain from illness, negative perceptions of illness, inefficient coping style and incorrect advice of treating physicians regarding RTW. Non-medical personal and environmental factors may either hinder or promote RTW and must be considered in the assessment of the work ability of long-term sick-listed employees. Assessment of work ability should start early during the sick leave period. These factors may be used by IPs to improve the quality of the assessment of the work ability of employees on long-term sick leave.

    The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation (MDCR), Massachusetts Department of Environmental Protection (MDEP), and the Massachusetts Department of Fish and Game (MDFG), conducted a preliminary investigation of fish communities in small- to medium-sized Massachusetts streams. The objective of this investigation was to determine relations between fish-community characteristics and anthropogenic alteration, including flow alteration and impervious cover, relative to the effect of physical basin and land-cover (environmental) characteristics. Fish data were obtained for 756 fish-sampling sites from the Massachusetts Division of Fisheries and Wildlife fish-community database. A review of the literature was used to select a set of fish metrics responsive to flow alteration. Fish metrics tested include two fish-community metrics (fluvial-fish relative abundance and fluvial-fish species richness), and five indicator species metrics (relative abundance of brook trout, blacknose dace, fallfish, white sucker, and redfin pickerel). Streamflows were simulated for each fish-sampling site using the Sustainable Yield Estimator application (SYE). Daily streamflows and the SYE water-use database were used to determine a set of indicators of flow alteration, including percent alteration of August median flow, water-use intensity, and withdrawal and return-flow fraction. The contributing areas to the fish-sampling sites were delineated and used with a Geographic Information System (GIS) to determine a set of environmental characteristics, including elevation, basin slope, percent sand and gravel, percent wetland, and percent open water, and a set of anthropogenic-alteration variables, including impervious cover and dam density. Two analytical techniques, quantile regression and generalized linear modeling, were applied to determine the association between fish-response variables and the selected environmental and

    This paper describes a multilevel youth violence prevention effort called SAFER Latinos (Seguridad, Apoyo, Familia, Educacion, y Recursos), a collaboration between The George Washington University School of Public Health and Health Services (GWU) and two key Latino community organizations. To implement and evaluate an intervention addressing factors within the social ecology of an immigrant Latino community. The intervention includes (1) Social promotores for family outreach and problem resolution; (2) Youth peer advocates at the high school level; (3) a drop-in center with support services for families and youth; and (4) community events, capacity building, and messages. Evaluation includes a baseline and follow-up surveys (N = 1,400) and focus groups. (1) Community circumstances change, requiring regular program adaptation. (2) Community interventions with research face potential contradictions in purpose impacting management of the collaboration and model fidelity. (3) Etiological models tied to interventions may have to be revisited owing to changes in the character and dynamics of the immigrant community.

    The U.S. Agency for Healthcare Research and Quality (AHRQ) developed a hospital patient safety culture survey in 2004 and has adapted this survey to other healthcare settings, such as nursing homes and medical offices, and most recently, community pharmacies. However, it is unknown whether safety culture dimensions developed for hospitals can be transferred to community pharmacies. The aim of this study was to assess the psychometric properties of the Community Pharmacy Survey on Patient Safety Culture. The survey was administered to 543 community pharmacists in Wisconsin, USA. Confirmatory factor analysis was used to assess the fit of our data with the proposed AHRQ model. Exploratory factor analysis was used to determine the underlying factor structure. Internal consistency reliabilities were calculated. A total of 433 usable surveys were returned (response rate 80%). Results from the confirmatory factor analysis showed inadequate model fit for the original 36 item, 11-factor structure. Exploratory factor analysis showed that a modified 27-item, four-factor structure better reflected the underlying safety culture dimensions in community pharmacies. The communication openness factor, with three items, dropped in its entirety while six items dropped from multiple factors. The remaining 27 items redistributed to form the four-factor structure: safety-related communication, staff training and work environment, organisational response to safety events, and staffing, work pressure and pace. Cronbach's α of 0.95 suggested good internal consistency. Our findings suggest that validation studies need to be conducted before applying safety dimensions from other healthcare settings into community pharmacies.

    The present study focused on bryophyte species composition, species diversity and the relationship between bryophyte communities and environmental factors in urban area of Chongqing City, by using biodiversity indices and the canonical correspondence analysis (CCA), based on the data of 44 plots. The results revealed that 86 species belonging to 43 genera and 25 families were found in saxicolous bryophyte communities, while 46 species belonging to 28 genera and 22 families were found in terricolous ones. The diversity indices of both saxicolous and terricolous bryophyte communities from campuses were higher than those of parks, natural scenic resorts, Jinyunshan National Nature Reserve. TWINSPAN classified saxicolous and terricolous bryophyte communities into three and two groups, respectively. CCA results showed canopy density was the major environmental factor of saxicolous bryophyte communities influencing bryophyte distribution in parks and campuses, whereas altitude, relative humidity and human disturbance were the major environmental factors in natural scenic resorts and nature reserve. Soil pH, canopy density and human disturbance were the major environmental factors in terricolous bryophyte communities in parks and campuses, whereas altitude, relative humidity and water content of the soil were the major environmental factors in those of natural scenic resorts and nature reserve.

    Objectives. I examined community risk factors that explained variation in suicide rates among young rural Alaska Native men, evaluating the effectiveness of local alcohol control as a public health policy to reduce this population’s historically high vulnerability. Methods. I compiled suicide data, alcohol control status, and community-level social, cultural, and economic characteristics for Alaska Native men aged 15 to 34 years in 178 small Alaska communities from 1980 to 2007. Poisson regression equations explained variation in suicide rates as a function of endogenous alcohol control and community characteristics. Results. Suicide rates were higher in communities prohibiting alcohol importation under state law, but the effect was not significant after controlling for other community characteristics. More remote communities, those with fewer non-Natives, and those with evidence of cultural divides had higher suicide risks. Communities with higher incomes, more married couples, and traditional elders had lower risks. Conclusions. Alcohol control is ineffective in preventing suicide among Alaska Natives; suicide instead appears related to particular complex community characteristics that are either protective or increase risk. Communities have limited means to pursue economic and cultural development strategies that might offer more protection. PMID:24754505

    Objective To systematically identify factors associated with participation in social and community activities for adult wheelchair users (WCUs). Data Sources Pubmed/MEDLINE, CINAHL, PsycINFO, EMBASE. Study Selection Quantitative and qualitative peer-reviewed publications were included which were written in English, reported original research, and investigated factors associated with social and community participation in adult WCUs. Data Extraction The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used; factors were organized using the International Classification of Functioning, Disability and Health (ICF). Data Synthesis Thirty-five studies were selected: two of power WCUs, 10 of manual WCUs, and 23 of both. Six qualitative studies, ranging in quality from 8/10 to 9/10, and 29 quantitative studies were included, ranging in quality from 4/15 to 11/15. Fifteen Body Function, four Activity, five Participation, 15 Environmental, and 14 Personal Factors were found to be associated with social and community participation. Conclusions Social and community participation of wheelchair users is associated with factors from all ICF domains. Wheelchair factors, accessibility, skills with wheelchair use, pain, finances, and education are modifiable factors frequently reported to be associated with participation. Experimental research focusing on modifiable factors is needed to further our understanding of factors influencing participation among wheelchair users. PMID:25472004

    The prevailing theoretical model of the Schizotypal Personality Questionnaire (SPQ) is a three-factor model based on subscale-level analyses. However, recent item-level factor analyses of the SPQ suggest a four- or five-factor model. To examine the factor structure of the SPQ and how this structure may differ between undergraduate and community samples, the authors conducted exploratory and confirmatory item-level factor analyses of this measure on undergraduate (N = 1,850) and community participants (N = 1,464). A clear three-factor solution was found in the community sample, whereas a somewhat equivocal four-factor solution was found in the undergraduate sample. Both structures displayed gender invariance. This is the first study to address the issues of undergraduate sample generalizability and gender invariance in an item-level exploratory factor analysis of the SPQ. Given the disparate findings in the samples, this study indicates the importance of using both community and undergraduate samples when examining the factor structure of the SPQ.

    The gastrointestinal tract harbors large and diverse populations of bacteria that vary among individuals and within individuals over time. Numerous internal and external factors can influence the contents of these microbial communities, including diet, geography, physiology, and the extent of contact among hosts. To investigate the contributions of such factors to the variation and changes in gut microbial communities, we analyzed the distal gut microbiota of individual chimpanzees from two communities in Gombe National Park, Tanzania. These samples, which were derived from 35 chimpanzees, many of whom have been monitored for multiple years, provide an unusually comprehensive longitudinal depth for individuals of known genetic relationships. Although the composition of the great-ape microbiota has been shown to codiversify with host species, indicating that host genetics and phylogeny have played a major role in its differentiation over evolutionary timescales, the geneaological relationships of individual chimpanzees did not coincide with the similarity in their gut microbial communities. However, the inhabitants from adjacent chimpanzee communities could be distinguished based on the contents of their gut microbiota. Despite the broad similarity of community members, as would be expected from shared diet or interactions, long-term immigrants to a community often harbored the most distinctive gut microbiota, suggesting that individuals retain hallmarks of their previous gut microbial communities for extended periods. This pattern was reinforced in several chimpanzees sampled over long temporal scales, in which the major constituents of the gut microbiota were maintained for nearly a decade. PMID:22826227

    Symbiotic bacteria often help their hosts acquire nutrients from their diet, showing trends of co-evolution and independent acquisition by hosts from the same trophic levels. While these trends hint at important roles for biotic factors, the effects of the abiotic environment on symbiotic community composition remain comparably understudied. In this investigation, we examined the influence of abiotic and biotic factors on the gut bacterial communities of fish from different taxa, trophic levels and habitats. Phylogenetic and statistical analyses of 25 16S rRNA libraries revealed that salinity, trophic level and possibly host phylogeny shape the composition of fish gut bacteria. When analysed alongside bacterial communities from other environments, fish gut communities typically clustered with gut communities from mammals and insects. Similar consideration of individual phylotypes (vs. communities) revealed evolutionary ties between fish gut microbes and symbionts of animals, as many of the bacteria from the guts of herbivorous fish were closely related to those from mammals. Our results indicate that fish harbour more specialized gut communities than previously recognized. They also highlight a trend of convergent acquisition of similar bacterial communities by fish and mammals, raising the possibility that fish were the first to evolve symbioses resembling those found among extant gut fermenting mammals.

    This study aimed to identify treatment, therapist and patient factors associated with dropping out of treatment in four outpatient mental health services. The experimental group comprised all 789 individuals who attended for the first time the mental health services during one year and dropped out of treatment in the same year or during the two following ones. The control group consisted of the same number of individuals, chosen at random from patients who, in the same year, attended for the first time the services and did not subsequently drop out of treatment. The overall drop-out rate was 33.2%. According to logistic regression analysis, the predictive factors of dropping out were: being treated in a particular centre, the involvement of more than one therapist in treatment, having no previous history of psychiatric disorders, being young and being male.

    Aim Although patterns are emerging for macroorganisms, we have limited understanding of the factors determining soil microbial community composition and productivity at large spatial extents. The overall objective of this study was to discern the drivers of microbial community composition at the extent of biogeographical provinces and regions. We hypothesized that factors associated with land use and climate would drive soil microbial community composition and biomass. Location Great Basin Province, Desert Province and California Floristic Province, California, USA. Methods Using phospholipid fatty acid analysis, we compared microbial communities across eight land-use types sampled throughout the State of California, USA (n = 1117). Results The main factor driving composition and microbial biomass was land-use type, especially as related to water availability and disturbance. Dry soils were more enriched in Gram-negative bacteria and fungi, and wetter soils were more enriched in Gram-positive, anaerobic and sulphate-reducing bacteria. Microbial biomass was lowest in ecosystems with the wettest and driest soils. Disturbed soils had less fungal and more Gram-positive bacterial biomass than wildland soils. However, some factors known to influence microbial communities, such as soil pH and specific plant taxa, were not important here. Main conclusions Distinct microbial communities were associated with land-use types and disturbance at the regional extent. Overall, soil water availability was an important determinant of soil microbial community composition. However, because of the inclusion of managed and irrigated agricultural ecosystems, the effect of precipitation was not significant. Effects of environmental and management factors, such as flooding, tillage and irrigation, suggest that agricultural management can have larger effects on soil microbial communities than elevation and precipitation gradients.

    The German Society for Psychiatry, Psychotherapy and Neurology (DGPPN) guidelines on psychosocial interventions for people with severe mental illness appraise the transferability of results of trials evaluating community-based mental health services to the German situation. This assessment has to draw on research results on factors determining effectiveness. This must be seen against the background of a lack of high-quality trials in Germany. The article discusses system, context and setting factors related to the transfer of evidence on community-based service models from other countries. These issues are discussed on the basis of evidence concerning the models of case management, assertive community treatment and community mental health teams. International differences in study findings are highlighted and the importance of treatment-as-usual in influencing study results is emphasized. The more control services including elements of community-based care there are and the less the pressure to reduce inpatient treatment (threshold to inpatient care admission), the smaller the relative effect sizes of innovative care models will be.In the absence of direct evidence, careful examination of transferability is required before introducing health care models. Research has revealed solid evidence for several factors influencing the effects of innovative community mental health care. Among key factors in the care of people with severe mental illness, home visits and joint team responsibility for both psychiatric and social care were identified. This evidence can facilitate the adaptation of successful mental health care models in Germany.

    This study developed and validated a model for predicting the probability that communities in Amhara Region, Ethiopia, have low sanitation coverage, based on environmental and sociodemographic conditions. Community sanitation coverage was measured between 2011 and 2014 through trachoma control program evaluation surveys. Information on environmental and sociodemographic conditions was obtained from available data sources and linked with community data using a geographic information system. Logistic regression was used to identify predictors of low community sanitation coverage (< 20% versus ≥ 20%). The selected model was geographically and temporally validated. Model-predicted probabilities of low community sanitation coverage were mapped. Among 1,502 communities, 344 (22.90%) had coverage below 20%. The selected model included measures for high topsoil gravel content, an indicator for low-lying land, population density, altitude, and rainfall and had reasonable predictive discrimination (area under the curve = 0.75, 95% confidence interval = 0.72, 0.78). Measures of soil stability were strongly associated with low community sanitation coverage, controlling for community wealth, and other factors. A model using available environmental and sociodemographic data predicted low community sanitation coverage for areas across Amhara Region with fair discrimination. This approach could assist sanitation programs and trachoma control programs, scaling up or in hyperendemic areas, to target vulnerable areas with additional activities or alternate technologies.

(b) To discover the association between parental education, socioeconomic status (SES) and family type (nuclear or joint) with knowledge, attitudes and practices regarding risk factors for otitis media. Using a cluster sampling design, the caregivers of 150 children attending daycare were interviewed to note knowledge, attitudes and practices with respect to risk factors for otitis media. Data on level of education of the caregiver, house type (an indicator of SES) and type of family structure were noted. A questionnaire was administered to collect all the relevant data. Statistical analysis of the data obtained was performed to note frequencies. Correlations between sociodemographic parameters and knowledge, attitudes and practices were studied using Chi-square test of proportions. Over 50% of the population showed knowledge deficits with regard to the various risk factors for otitis media. Caregivers from nuclear families were slightly less knowledgeable regarding lack of immunization and household smoke as risk factors for the disease. There was no correlation between any of the sociodemographic factors and attitudes. However, educated mothers were more likely than illiterate mothers to clean their children's ears of wax on a regular basis with the belief that it would prevent ear disease (p=0.05). Treatment practices in the community were more or less uniform in that earache was either disregarded (26.4%) or treated with home remedies (67.2%) by most caregivers, while a doctor's opinion was often sought for ear discharge (50%). Parents of higher SES were more likely to use home remedies than those of lower SES (p=0.008). Sociodemographic factors as well as poor knowledge and attitudes and unhealthy practices with respect to risk factors of otitis media contribute to the high prevalence of

    The bioconcentration factor (BCF) is an important bioaccumulation hazard assessment metric in many regulatory contexts. Its assessment is required by the REACH regulation (Registration, Evaluation, Authorization and Restriction of Chemicals) and by CLP (Classification, Labeling and Packaging). We challenged nine well-known and widely used BCF QSAR models against 851 compounds stored in an ad-hoc created database. The goodness of the regression analysis was assessed by considering the determination coefficient (R(2)) and the Root Mean Square Error (RMSE); Cooper's statistics and Matthew's Correlation Coefficient (MCC) were calculated for all the thresholds relevant for regulatory purposes (i.e. 100L/kg for Chemical Safety Assessment; 500L/kg for Classification and Labeling; 2000 and 5000L/kg for Persistent, Bioaccumulative and Toxic (PBT) and very Persistent, very Bioaccumulative (vPvB) assessment) to assess the classification, with particular attention to the models' ability to control the occurrence of false negatives. As a first step, statistical analysis was performed for the predictions of the entire dataset; R(2)>0.70 was obtained using CORAL, T.E.S.T. and EPISuite Arnot-Gobas models. As classifiers, ACD and logP-based equations were the best in terms of sensitivity, ranging from 0.75 to 0.94. External compound predictions were carried out for the models that had their own training sets. CORAL model returned the best performance (R(2)ext=0.59), followed by the EPISuite Meylan model (R(2)ext=0.58). The latter gave also the highest sensitivity on external compounds with values from 0.55 to 0.85, depending on the thresholds. Statistics were also compiled for compounds falling into the models Applicability Domain (AD), giving better performances. In this respect, VEGA CAESAR was the best model in terms of regression (R(2)=0.94) and classification (average sensitivity>0.80). This model also showed the best regression (R(2)=0.85) and sensitivity (average>0.70) for

    Links between microbial community assemblages and geogenic factors were assessed in 187 soil samples collected from four metal-rich provinces across Australia. Field-fresh soils and soils incubated with soluble Au(III) complexes were analysed using three-domain multiplex-terminal restriction fragment length polymorphism, and phylogenetic (PhyloChip) and functional (GeoChip) microarrays. Geogenic factors of soils were determined using lithological-, geomorphological- and soil-mapping combined with analyses of 51 geochemical parameters. Microbial communities differed significantly between landforms, soil horizons, lithologies and also with the occurrence of underlying Au deposits. The strongest responses to these factors, and to amendment with soluble Au(III) complexes, was observed in bacterial communities. PhyloChip analyses revealed a greater abundance and diversity of Alphaproteobacteria (especially Sphingomonas spp.), and Firmicutes (Bacillus spp.) in Au-containing and Au(III)-amended soils. Analyses of potential function (GeoChip) revealed higher abundances of metal-resistance genes in metal-rich soils. For example, genes that hybridised with metal-resistance genes copA, chrA and czcA of a prevalent aurophillic bacterium, Cupriavidus metallidurans CH34, occurred only in auriferous soils. These data help establish key links between geogenic factors and the phylogeny and function within soil microbial communities. In particular, the landform, which is a crucial factor in determining soil geochemistry, strongly affected microbial community structures. PMID:22673626

PhyloChip analyses revealed a greater abundance and diversity of Alphaproteobacteria (especially Sphingomonas spp.), and Firmicutes (Bacillus spp.) in Au-containing and Au(III)-amended soils. Analyses of potential function (GeoChip) revealed higher abundances of metal-resistance genes in metal-rich soils. For example, genes that hybridised with metal-resistance genes copA, chrA and czcA of a prevalent aurophillic bacterium, Cupriavidus metallidurans CH34, occurred only in auriferous soils. These data help establish key links between geogenic factors and the phylogeny and function within soil microbial communities. In particular, the landform, which is a crucial factor in determining soil geochemistry, strongly affected microbial community structures.

    Background US Hispanics have disproportionate rates of diabetes and other chronic diseases. We used the entertainment–education approach to develop a Spanish-language radio novella aimed at reducing risk factors for diabetes, obesity, and tobacco use. The approach is based on social cognitive theory and proposes modeling as a source of vicarious learning of outcome and efficacy expectations. Community Context The Hispanic population in Alabama increased by 145% between 2000 and 2010. Nearly one-quarter of Hispanics aged 18 to 64 live below the federal poverty level, and 49% are uninsured. Several lifestyle factors lead to poor health behaviors in this community. Radio is a popular medium among Hispanic immigrants. The single local Spanish-language radio station reaches a large proportion of the local community and several communities beyond. Methods Through various methods, including workshops, review sessions, and other feedback mechanisms, we engaged stakeholders and community members in developing and evaluating a 48-episode radio novella to be broadcast as part of a variety show. We tracked participation of community members in all phases. Outcome Community members participated significantly in developing, broadcasting, and evaluating the intervention. The desired outcome — development of a culturally relevant storyline that addresses salient health issues and resonates with the community — was realized. Interpretation Our approach to community engagement can serve as a model for other organizations wishing to use community-based participatory methods in addressing Hispanic health issues. The radio novella was a unique approach for addressing health disparities among our community’s Hispanic population. PMID:22863307

    The natural events such as earthquakes turn out to be disasters as a result of not only the poor conditions of the built area and infrastructure, but also affected by the socioeconomic fragility and lack of resilience of the community exposed. Likewise, resilience factors play role in increasing the ability of people to cope with hazards. Social resilience is the capacity of social groups and communities to recover from, or respond positively to, crises. Emergency management plans must recognize and build on this capacity, and that improved indicators of social resilience should receive priority consideration in the application of these plans. The physical risk factors and their damage assessment have been pointed out in previous earthquake risk assessment and scenario studies conducted by Bogazici University and OYO International. A rational assessment of the risk aggravating factors is essential in order to reach to a more complete coverage of the overall risk. It would also introduce the social factors that need to be reduced or strengthened through public policies and actions in order to increase the resilience of the community. With experience from several social studies conducted under CENDIM, Kandilli Observatory & Earthquake Research Institute's Disaster Preparedness Education Unit, and research of the studies conducted by several other national and international institutions, we are defining the community disaster preparedness as an indicator for resilience. Social resilience is understood to have two important properties: resistance, recovery. Resistance relates to a community's efforts to withstand a disaster and its consequences whereas recovery relates to a community's ability to coming back to its pre-disaster level of "normalcy". Researches also indicate that the need for local-level and community-based approaches is recognized in achieving sustainable hazard risk reduction. We will conceptually discuss the description and assessment of the community

    Two hundred and five cases (mean age 13.4, SD 9.5) of persistent diarrhoea (PD) of 14-28 days duration, attending an urban slum clinic and treated according to standard WHO guidelines, were monitored at weekly intervals to obtain an estimate of treatment failure rates and to identify its clinical predictors. Vitamin and micronutrients (daily 2RDA) were additionally provided. Only 9 (8.2%) of 109 children with criteria for hospital care accepted in-patient care. Weight gain was considered inadequate if the daily increment between enrollment and day 7 of follow up was < 10 g at age 0-3 months, < 5 g at 4-6 months, and any weight loss for those older than 6 months. Recovery was considered delayed if diarrhoea ceased 7 days after enrollment. Overall, 28.3% cases had inadequate weight gain and 25.6% had delayed recovery. The non-breast milk calorie intake was 11.2% during infancy and 40.6% at later ages of the recommended intakes. In a logistic regression model, initial watery stool frequency greater than median (adjusted OR 2.30, p = 0.01), age < or = 6 months (adjusted OR 2.24, p = 0.04) and low consumption of micronutrient mixture (adjusted OR 2.62, p = 0.01) were associated with an increased risk of delayed recovery. In a Cox proportional hazards model for time to recovery from diarrhoea, low consumption of the micronutrient mixture and age < or = 6 months reduced the chances of recovery by 29% and 37% respectively. Low consumption of the prescribed micronutrient mixture (adjusted OR 2.21, p = 0.04), fever (adjusted OR 1.91, p = 0.05) and diarrhoea continuing beyond study day 7 (adjusted OR 2.29, p = 0.03) increased the risk of inadequate weight gain. Breast feeding status and animal milk consumption did not influence weight gain or recovery. Due to the low compliance for advised hospitalisation, approaches for care at community level itself need to be evolved. Focus should be on increasing the overall dietary intake and provision of generous but safe amount of

    To study the effect that copper residues exert on bacterial communities and the ability of bacteria to colonize different microhabitats in abandoned tailing dumps. We used the terminal-restriction fragment length polymorphism technique, a culture-independent molecular approach based on PCR amplification of ribosomal genes, to compare the structure of the bacterial communities from samples taken at two nearby located abandoned tailing dumps found in the Mediterranean-climate area of central Chile. Our results show that elevated available copper content in tailings has a strong effect on the bacterial community composition, but that other factors like pH and organic matter content also play an important role in the structure of these communities. We also found that the number of abundant bacteria in these samples was significantly lower than in soils not exposed to metal pollution. In addition to bioavailable copper, bacterial communities found in copper-tailings dumps are also affected by several other environmental factors. This first report on environmental factors influencing microbial communities in copper-tailings dumps will help to devise appropriate restoration procedures in this type of polluted habitat.

    To systematically identify factors associated with participation in social and community activities for adult wheelchair users (WCUs). PubMed/MEDLINE, CINAHL, PsycINFO and EMBASE. Quantitative and qualitative peer-reviewed publications were included, which were written in English, reported original research and investigated factors associated with social and community participation in adult WCUs. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used. Factors were organized using the International Classification of Functioning, Disability and Health (ICF). Thirty-five studies were selected: two of power WCUs, 10 of manual WCUs and 23 of both. Six qualitative studies, ranging in quality from 8/10 to 9/10 and 29 quantitative studies were included, ranging in quality from 4/15 to 11/15. Fifteen body function, 4 activity, 5 participation, 15 environmental and 14 personal factors were found to be associated with social and community participation. Social and community participation of WCUs is associated with factors from all ICF domains. Wheelchair factors, accessibility, skills with wheelchair use, pain, finances and education are modifiable factors frequently reported to be associated with participation. Experimental research focusing on modifiable factors is needed to further our understanding of factors influencing participation among WCUs. Implications for Rehabilitation Wheelchair factors, including comfort and durability, are associated with participation and may be targeted in clinical intervention. Wheelchair skills are clinically modifiable and have been shown to improve participation in manual wheelchair users. Body functions (e.g. confidence, depression and fatigue) and personal factors (e.g. finances and level of education) may be considered for clinical intervention.

    A variety of measures of sense of community have been developed, but the identification of latent factors in developed scales to measure this construct have encountered significant psychometric problems involving reliability and validity. We present a new measure called the Psychological Sense of Community Scale, which is based on 3 distinct ecological domains involving the individual, microsystem and macrosystem. We used an exploratory factor analysis to investigate our three theoretical domains involving Self (identity and importance to self), Membership (social relationships), and Entity (a group's organization and purpose). Three theoretically derived factors emerged with good measurement model fit, internal reliabilities, and convergent validity. Our study also found multiplicative over additive effects, suggesting each of the 3 domains is necessary to understand the experience of sense of community. This scale can be adapted to a variety of contexts and situations in future research. PMID:27667867

    This paper presents a review of the empirical literature for studies evaluating factors that facilitate and create barriers to sustained program implementation in disadvantaged communities. It outlines study methodology and sustainment outcomes and proposes a conceptual model that involves implementation sustainment support for providers delivering evidence-based health and family services in disadvantaged communities. Sustained program implementation in the community setting is a significant issue as only 43% of studies reported successfully sustained programs. The review identified 18 factors that facilitate success and create barriers to program sustainment. The factors are synthesized into three themes; program characteristics, workplace capacity, and process and interaction factors. The majority of factors map onto commonly cited sustainability influences in implementation science. However, there was an additional focus for studies included in this review on the importance of factors such as program burden, program familiarity and perceived competence in program skills, workplace support for the program, staff mobility and turnover, supervision and peer support, and ongoing technical assistance. The need to use a conceptual framework and develop measures to guide and evaluate capacity building in EBP implementation and sustainment in low-resource community settings is highlighted.

    Beta-diversity, defined as spatial replacement in species composition, is crucial to the understanding of how local communities assemble. These changes can be driven by environmental or geographic factors (such as geographic distance), or a combination of the two. Spiders have been shown to be good indicators of environmental quality. Accordingly, spiders are used in this work as model taxa to establish whether there is a decrease in community similarity that corresponds to geographic distance in the grasslands of the Campos & Malezales ecoregion (Corrientes). Furthermore, the influence of climactic factors and local vegetation heterogeneity (environmental factors) on assemblage composition was evaluated. Finally, this study evaluated whether the differential dispersal capacity of spider families is a factor that influences their community structure at a regional scale. Spiders were collected with a G-Vac from vegetation in six grassland sites in the Campos & Malezales ecoregion that were separated by a minimum of 13 km. With this data, the impact of alpha-diversity and different environmental variables on the beta-diversity of spider communities was analysed. Likewise, the importance of species replacement and nesting on beta-diversity and their contribution to the regional diversity of spider families with different dispersion capacities was evaluated. The regional and site-specific inventories obtained were complete. The similarity between spider communities declined as the geographic distance between sites increased. Environmental variables also influenced community composition; stochastic events and abiotic forces were the principal intervening factors in assembly structure. The differential dispersal capacity of spider groups also influenced community structure at a regional scale. The regional beta-diversity, as well as species replacement, was greater in high and intermediate vagility spiders; while nesting was greater in spiders with low dispersion

    This qualitative study explores community resilience factors within an indigenous Sámi community in Northern Norway. Semistructured interviews were conducted with 22 informants, 12 females and 10 males, ranging in age from 13 to 19 years old, 12 of whom had reindeer husbandry affiliation. Data analysis used a modified grounded theory approach and narrative analysis. Interpretation of the data was based on ecological perspectives theory and the identification of possible community resilience factors including Sámi language competence, use of recreational and natural resources, and traditional ecological knowledge, such as reindeer husbandry related activities. These cultural factors appear to strengthen adolescents' ethnic identity and pride, which in turn act as potential resilience mechanisms. Land was a significant arena for traditional practices and recreation. The majority of the youth reported support from relationships with extended godparents (fáddarat) and extended family (sohka) networks. The fáttar network was particularly strong among adolescents with reindeer husbandry affiliations. Native language competence and reindeer husbandry were key components in adolescent social networks. Interconnectedness among the community members and with the environment seemed to promote resilience and well-being. Two factors that excluded adolescents from full community membership and participation were being a nonnative Sámi language speaker and the absence of extended Sámi family networks. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    This study shows that the geogenic factors landform, lithology, and underlying mineral deposits (expressed by elevated metal concentrations in overlying soils) are key drivers of microbial community diversity in naturally metal-rich Australian soils with different land uses, i.e., agriculture versus natural bushland. One hundred sixty-eight soil samples were obtained from two metal-rich provinces in Australia, i.e., the Fifield Au-Pt field (New South Wales) and the Hillside Cu-Au-U rare-earth-element (REE) deposit (South Australia). Soils were analyzed using three-domain multiplex terminal-restriction-fragment-length-polymorphism (M-TRFLP) and PhyloChip microarrays. Geogenic factors were determined using field-mapping techniques and analyses of >50 geochemical parameters. At Fifield, microbial communities differed significantly with geogenic factors and equally with land use (P < 0.05). At Hillside, communities in surface soils (0.03- to 0.2-m depth) differed significantly with landform and land use (P < 0.05). Communities in deeper soils (>0.2 m) differed significantly with lithology and mineral deposit (P < 0.05). Across both sites, elevated metal contents in soils overlying mineral deposits were selective for a range of bacterial taxa, most importantly Acidobacteria, Bacilli, Betaproteobacteria, and Epsilonproteobacteria. In conclusion, long-term geogenic factors can be just as important as land use in determining soil microbial community diversity. PMID:26341204

    PURPOSE: The study seeks to examine whether the relationships among community, family, individual factors, and violent behavior are parallel across race- and gender-specific segments of the adolescent population. METHODS: Data from the National Longitudinal Study of Adolescent Health are analyzed to highlight the complex relationships between inequality, community, family, individual behavior, and violence. RESULTS: The results from robust regression analysis provide evidence that social environmental factors can influence adolescent violence in race- and gender-specific ways. CONCLUSIONS: Findings from this study establish the plausibility of multidimensional models that specify a complex relationship between inequality and adolescent violence. PMID:15101669

    The bioconcentration factor (BCF) is an important bioaccumulation hazard assessment metric in many regulatory contexts. Its assessment is required by the REACH regulation (Registration, Evaluation, Authorization and Restriction of Chemicals) and by CLP (Classification, Labeling and Packaging). We challenged nine well-known and widely used BCF QSAR models against 851 compounds stored in an ad-hoc created database. The goodness of the regression analysis was assessed by considering the determination coefficient (R{sup 2}) and the Root Mean Square Error (RMSE); Cooper's statistics and Matthew's Correlation Coefficient (MCC) were calculated for all the thresholds relevant for regulatory purposes (i.e. 100 L/kg for Chemical Safety Assessment; 500 L/kg for Classification and Labeling; 2000 and 5000 L/kg for Persistent, Bioaccumulative and Toxic (PBT) and very Persistent, very Bioaccumulative (vPvB) assessment) to assess the classification, with particular attention to the models' ability to control the occurrence of false negatives. As a first step, statistical analysis was performed for the predictions of the entire dataset; R{sup 2}>0.70 was obtained using CORAL, T.E.S.T. and EPISuite Arnot–Gobas models. As classifiers, ACD and log P-based equations were the best in terms of sensitivity, ranging from 0.75 to 0.94. External compound predictions were carried out for the models that had their own training sets. CORAL model returned the best performance (R{sup 2}{sub ext}=0.59), followed by the EPISuite Meylan model (R{sup 2}{sub ext}=0.58). The latter gave also the highest sensitivity on external compounds with values from 0.55 to 0.85, depending on the thresholds. Statistics were also compiled for compounds falling into the models Applicability Domain (AD), giving better performances. In this respect, VEGA CAESAR was the best model in terms of regression (R{sup 2}=0.94) and classification (average sensitivity>0.80). This model also showed the best regression (R{sup 2

    Numerous factors impact patients' health beyond traditional clinical characteristics. We evaluated the association of risk factors in kidney transplant patients' communities with outcomes prior to transplantation. The primary exposure variable was a community risk score (range 0-40) derived from multiple databases and defined by factors including prevalence of comorbidities, access and quality of healthcare, self-reported physical and mental health and socioeconomic status for each U.S. county. We merged data with the Scientific Registry of Transplant Recipients (SRTR) and utilized risk-adjusted models to evaluate effects of community risk for adult candidates listed 2004-2010 (n = 209 198). Patients in highest risk communities were associated with increased mortality (adjusted hazard ratio [AHR] = 1.22, 1.16-1.28), decreased likelihood of living donor transplantation (adjusted odds ratio [AOR] = 0.90, 0.85-0.94), increased waitlist removal for health deterioration (AHR = 1.36, 1.22-1.51), decreased likelihood of preemptive listing (AOR = 0.85, 0.81-0.88), increased likelihood of inactive listing (AOR = 1.49, 1.43-1.55) and increased likelihood of listing for expanded criteria donor kidneys (AHR = 1.19, 1.15-1.24). Associations persisted with adjustment for rural-urban location; furthermore the independent effects of rural-urban location were largely eliminated with adjustment for community risk. Average community risk varied widely by region and transplant center (median = 21, range 5-37). Community risks are powerful factors associated with processes of care and outcomes for transplant candidates and may be important considerations for developing effective interventions and measuring quality of care of transplant centers. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Mediterranean coastal dunes are dynamic and heterogeneous ecosystems characterised by a strong interaction between abiotic and biotic factors. The present study aimed to adopt a multidisciplinary approach - integrating data on dune morphology, sediment texture and soil parameters as well as shoreline trend - in order to define which are the abiotic factors that most affect the distribution and composition of Mediterranean plant dune communities. The study was carried out in two protected areas, located in central Italy, subjected to different shoreline trends in recent years. 75 plots were identified along eleven randomly positioned cross-shore transects, starting from the beach continuing up to the plant communities of the backdunes. In each plot floristic and environmental data - such as distance to the coastline, plot altitude, inclination, shoreline trend, mean grain-size, sorting, pH, conductivity and organic matter concentration - were collected. The analyses revealed significant changes of vegetational cover, dune morphology and geopedological features along the coast-to-inland gradient. Relationships between vegetation composition and environmental factors were investigated through Canonical Correspondence Analysis (CCA). Four factors - distance to the coastline, mean grain-size, shoreline trend and organic matter - were found to be closely correlated with the floristic composition of plant communities. Finally, soil properties were highlighted as the most determinant factors of community zonation in these Mediterranean coastal dune ecosystems. These results could be taken into account by local managers in conservation actions such as protecting the eroding foredunes as well as in artificial dune reconstructions.

    Plant communities are coupled with abiotic factors, as species diversity and community composition both respond to and influence climate and soil characteristics. Interactions between vegetation and abiotic factors depend on plant functional types (PFT) as different growth forms will have differential responses to and effects on site characteristics. However, despite the importance of different PFT for community assembly and ecosystem functioning, research has mainly focused on vascular plants. Here, we established a set of observational plots in two contrasting habitats in northeastern Siberia in order to assess the relationship between species diversity and community composition with soil variables, as well as the relationship between vegetation cover and species diversity for two PFT (nonvascular and vascular). We found that nonvascular species diversity decreased with soil acidity and moisture and, to a lesser extent, with soil temperature and active layer thickness. In contrast, no such correlation was found for vascular species diversity. Differences in community composition were found mainly along soil acidity and moisture gradients. However, the proportion of variation in composition explained by the measured soil variables was much lower for nonvascular than for vascular species when considering the PFT separately. We also found different relationships between vegetation cover and species diversity according the PFT and habitat. In support of niche differentiation theory, species diversity and community composition were related to edaphic factors. The distinct relationships found for nonvascular and vascular species suggest the importance of considering multiple PFT when assessing species diversity and composition and their interaction with edaphic factors. Synthesis: Identifying vegetation responses to edaphic factors is a first step toward a better understanding of vegetation-soil feedbacks under climate change. Our results suggest that incorporating

    Community pharmacists in the United States have significant opportunity to engage in community-level prescription substance abuse prevention and treatment efforts, including dissemination of information specific to available addiction treatment options. Our cross-sectional study of Tennessee community pharmacists noted that 26% had previously provided addiction treatment facility information to one or more patients in the past. The purpose of this study was to employ multivariate modeling techniques to investigate associations between community pharmacist and community pharmacy factors and past provision of addiction treatment information to pharmacy patients. Multivariate logistic regression indicated having addiction treatment facility information in a pharmacy setting (aOR=8.19; 95% CI=4.36-15.37), having high confidence in ability to discuss treatment facility options (aOR=4.16; 95% CI=2.65-6.52), having participated in prescription opioid abuse-specific continuing education (aOR=2.90; 95% CI=1.70-4.97), being male (aOR=2.23; 95% CI=1.38-3.59), and increased hours per week in the practice setting (aOR=1.02; 95% CI=1.004-1.05) were all significantly associated with provision of information about addiction treatment. Dissemination of addiction treatment information, improvements in communicative self-efficacy beliefs, and dissemination of prescription opioid abuse-specific continuing education are modifiable factors significantly associated with increased provision of addiction treatment information by community pharmacists.

    The factor analysis on the relationships between excess noise attenuation (decrement after noise propagating 30 m) and 8 structural characteristics of 19 urban plant communities in Shanghai showed that all the plant communities had notable effects on reducing noise, and the noise attenuation ability of the communities was significantly higher than that of lawn (P < 0.01). The plant communities could be divided into three groups base on their noise attenuation ability, i.e., those of > or = 10 dB(A), 6-10 dB(A), and < or = 6 dB(A). The main factors affecting the noise attenuation ability of the communities were leaf area index, average bifurcate height, average height, coverage, and average canopy diameter, and their correlation coefficients with noise attenuation were 0.343, 0.318, 0.285, 0.226 and 0.193, respectively. These five factors had a cumulative contribution rate of 65.47%, suggesting that they should be considered in stress when designing urban greenbelt for noise reduction.

    2010-01-01

    Background Well-trained and highly motivated community health workers (CHWs) are critical for delivery of many community-based newborn care interventions. High rates of CHW attrition undermine programme effectiveness and potential for implementation at scale. We investigated reasons for high rates of CHW attrition in Sylhet District in north-eastern Bangladesh. Methods Sixty-nine semi-structured questionnaires were administered to CHWs currently working with the project, as well as to those who had left. Process documentation was also carried out to identify project strengths and weaknesses, which included in-depth interviews, focus group discussions, review of project records (i.e. recruitment and resignation), and informal discussion with key project personnel. Results Motivation for becoming a CHW appeared to stem primarily from the desire for self-development, to improve community health, and for utilization of free time. The most common factors cited for continuing as a CHW were financial incentive, feeling needed by the community, and the value of the CHW position in securing future career advancement. Factors contributing to attrition included heavy workload, night visits, working outside of one's home area, familial opposition and dissatisfaction with pay. Conclusions The framework presented illustrates the decision making process women go through when deciding to become, or continue as, a CHW.

    Objective This study examined the role of static indicators and proximal, clinically relevant indicators in the prediction of short-term community violence in a large, heterogeneous sample of adults with mental illnesses. Methods Data were pooled from five studies of adults with mental illnesses (N=4,484). Follow-up data were available for 2,579 participants. A hierarchical linear regression assessed the incremental validity of a series of variable clusters in the prediction of violence risk at six months: static characteristics (age, sex, race-ethnicity, and primary diagnosis), substance use (alcohol use and drug use at baseline), clinical functioning (psychiatric symptoms at baseline and recent hospitalization), recent violence, and recent victimization. Results Results demonstrated improved prediction with each step of the model, indicating that proximal indicators contributed to the prediction of short-term community violence above and beyond static characteristics. When all variables were entered, current alcohol use, recent violence, and recent victimization were positive predictors of subsequent violence, even after the analysis controlled for participant characteristics. Conclusions This study provides empirical evidence for three proximal, clinically relevant indicators in the assessment and management of short-term violence risk among adults with mental illnesses: current alcohol use, recent violence, and recent victimization. Consideration of these indicators in clinical practice may assist in the identification of adults with mental illnesses who are at heightened risk of short-term community violence. PMID:26927580

    This article describes how a community coalition focusing on maternal and child health engages community participation through the use of geographic information systems (GIS) mapping, developing strategies that culminate in the implementation of a service delivery plan to improve birth outcomes. Vital statistics data from 2007 to 2009 was analyzed by zip code in Pinellas County Florida to produce choropleth thematic maps using ArcGIS for 3 year rolling average infant deaths and single year percentages for prematurity. The maps were presented at the organization's annual coalition meeting to discuss risk areas, changes over time in the selected indicators and solicit community feedback on how to best target issues addressing infant mortality and prematurity. The maps identified new zip codes of concern for prematurity in addition to known high risk zip codes for both infant mortality and prematurity. The community identified changes in demographic composition and changes in housing patterns, such as new mobile home areas, in the high risk areas. In response, the community assisted the Coalition in developing a holistic plan addressing risk factors affecting birth outcomes by expanding current services, hiring a nutritionist, and contracting a health navigator. When compared to tables and charts, a visual depiction of a neighborhood by recognizable zip codes is a useful tool to help community decision makers better visualize public health concerns and interpret trends based on local knowledge. Public health professionals should use this community knowledge to interpret research results and implement strategies to improve birth outcomes.

    Antibiotic ciprofloxacin is ubiquitous in the environment. However, little is known about ciprofloxacin dissipation by microbial community. The present study investigated the biodegradation potential of ciprofloxacin by mixed culture and the influential factors and depicted the structure of ciprofloxacin-degrading microbial community. Both the original microbiota from drinking water biofilter and the microbiota previously acclimated to high levels of ciprofloxacin could utilize ciprofloxacin as sole carbon and nitrogen sources, while the acclimated microbiota had a much stronger removal capacity. Temperature rise and the presence of carbon or nitrogen sources favored ciprofloxacin biodegradation. Many novel biotransformation products were identified, and four different metabolic pathways for ciprofloxacin were proposed. Bacterial community structure illustrated a profound shift with ciprofloxacin biodegradation. The ciprofloxacin-degrading bacterial community was mainly composed of classes Gammaproteobacteria, Bacteroidia, and Betaproteobacteria. Microorganisms from genera Pseudoxanthomonas, Stenotrophomonas, Phenylobacterium, and Leucobacter might have links with the dissipation of ciprofloxacin. This work can provide some new insights towards ciprofloxacin biodegradation.

    The current study investigated anxiety sensitivity, distress tolerance (Simons & Gaher, 2005), and discomfort intolerance (Schmidt, Richey, Cromer, & Buckner, 2007) in relation to panic-relevant responding (i.e., panic attack symptoms and panic-relevant cognitions) to a 10% carbon-dioxide enriched air challenge. Participants were 216 adults (52.6% female; M age = 22.4, SD = 9.0). A series of hierarchical multiple regressions was conducted with covariates of negative affectivity and past-year panic attack history in step one of the model, and anxiety sensitivity, discomfort intolerance, and distress tolerance entered simultaneously into step two. Results indicated that anxiety sensitivity, but not distress tolerance or discomfort intolerance, was significantly incrementally predictive of physical panic attack symptoms and cognitive panic attack symptoms. Additionally, anxiety sensitivity was significantly predictive of variance in panic attack status during the challenge. These findings emphasize the important, unique role of anxiety sensitivity in predicting risk for panic psychopathology, even when considered in the context of other theoretically-relevant emotion vulnerability variables.

    Here we show that verrucomicrobial community structure and abundance are extremely sensitive to changes in chemical factors linked to soil fertility. Terminal restriction fragment length polymorphism fingerprint and real-time quantitative PCR assay were used to analyze changes in verrucomicrobial communities associated with contrasting soil nutrient conditions in tropical regions. In case study Model I ("Slash-and-burn deforestation") the verrucomicrobial community structures revealed disparate patterns in nutrient-enriched soils after slash-and-burn deforestation and natural nutrient-poor soils under an adjacent primary forest in the Amazonia (R = 0.819, P = 0.002). The relative proportion of Verrucomicrobia declined in response to increased soil fertility after slash-and-burn deforestation, accounting on average, for 4 and 2 % of the total bacterial signal, in natural nutrient-poor forest soils and nutrient-enriched deforested soils, respectively. In case study Model II ("Management practices for sugarcane") disparate patterns were revealed in sugarcane rhizosphere sampled on optimal and deficient soil fertility for sugarcane (R = 0.786, P = 0.002). Verrucomicrobial community abundance in sugarcane rhizosphere was negatively correlated with soil fertility, accounting for 2 and 5 % of the total bacterial signal, under optimal and deficient soil fertility conditions for sugarcane, respectively. In nutrient-enriched soils, verrucomicrobial community structures were related to soil factors linked to soil fertility, such as total nitrogen, phosphorus, potassium and sum of bases, i.e., the sum of calcium, magnesium and potassium contents. We conclude that community structure and abundance represent important ecological aspects in soil verrucomicrobial communities for tracking the changes in chemical factors linked to soil fertility under tropical environmental conditions.

    Up to 4 million people in Tanzania are at risk for the parasitic disease onchocerciasis. A treatment program, Community-Directed Treatment with Ivermectin (CDTI), has made significant gains in prevention and treatment. Understanding factors affecting participation could help boost treatment coverage and sustain gains made in controlling onchocerciasis in endemic areas. To explore community-perceived factors related to participation in and sustainability of the CDTI program in southwest Tanzania. Multilevel triangulation design using surveys, focus group discussions (FGDs), and semistructured interviews to collect data in two villages in the Morogoro Rural District of Tanzania. In total, 456 villagers participated in the survey and 42 in FDGs. Five community-directed distributors (CDDs) and three community health workers were interviewed. High levels of awareness of onchocerciasis (90%) and methods of prevention and treatment (95%) were reported. Over 75% of participants knew how ivermectin was distributed and 74% have taken the drug. Over 90% of villagers knew that distribution of the drug was for treatment and prevention. Only 43% knew the cause of onchocerciasis. Through FGDs, villagers reported barriers to participation, including lack of comprehensive understanding of the disease, fears of medication, distrust of the method determining dose, lack of health education materials, insufficient CDD-resident communication, and inflexible drug distribution mechanisms. Sustaining programs without supporting growth of CDDs and reinforcing education of communities could lead to a decrease in treatment and an increase in the public health threat. This research uncovered a need for more effective community education and sensitization. Understanding barriers to participation in community-based programs can assist public health and community health nurses and key stakeholders including Ministries of Health and local and regional health systems in the development of education

    The government of Kenya launched its community health strategy in 2006 to improve certain aspects of its community health program. Under the strategy, community units (CUs) were established as level one of the Kenyan health system. A core member at this level is the community health worker (CHW). The objective of this study was to assess the relationship among the performance of the CUs, the prevalence of childhood diarrhea and appropriate treatment for it by controlling individual and community-level factors. The main dataset used in this study was the 2011 Nyanza Province county-based Multiple Indicator Cluster Survey (MICS). In addition, based on the list of community units in Nyanza Province, Kenya, we identified the area's CUs and their performance. MICS data and data on CUs were merged using sub-location names. There were 17 individual and two community-level independent variables in this study. Bivariate analysis and a multilevel logistic regression were performed. Factors significantly associated with a lower prevalence of diarrhea among children under five were the child's increasing age, middle-aged household heads, children who received more attention, water treatment and rural versus urban area residence, while male children and highly performing CUs were significantly associated with a higher prevalence of diarrhea. In addition, middle wealth index, severity of diarrhea and middle- and high-CU performance were significantly associated with appropriate treatment for childhood diarrhea. Although this study found that children living in areas of high CU performance were more likely to have diarrhea, these areas would have been identified as being more at risk for diarrhea prevalence and other health concerns, prioritized for the establishment of a CU and allocated more resources to improve the performance of CUs. A higher CU performance was significantly associated with the appropriate treatment. It was suggested that CHWs could have a positive effect on

  14. The interface of family, school, and community factors for the positive development of children and youth.

    2010-01-01

    In this issue, we examine the application of the ecological elements of family, school, and community on the developmental outcomes of children and youth. Five empirical articles then provide insight into the interaction of individual development, intelligence, and risk with contextual factors such as involvement, expectations, relationships, peers, and community. We conclude that individual child and youth outcomes are powerfully influenced by family involvement at a young age, but as age increases, this involvement becomes less salient. In youth considered "high risk," family and community protective factors were not able to significantly improve child outcomes. We specifically recommend that practitioners target interventions for high risk audiences that are guided by assessments of the child's developmental and risk profiles.

    PubMed

    Seligowski, Antonia V; Orcutt, Holly K

    2016-03-01

    Research suggests that 4-factor models of posttraumatic stress disorder (PTSD) may be improved upon by the addition of novel factors, such as Dysphoric Arousal, Externalizing Behaviors, and Anhedonia. However, a novel 7-factor hybrid model has demonstrated superior fit in veteran and undergraduate samples. The current study sought to replicate this finding in a trauma-exposed community sample and examined relations with positive (PA) and negative affect (NA). Participants included 403 adults (M(age) = 37.75) recruited through Amazon's MTurk. PTSD was measured using the PTSD Checklist-5 (PCL-5). Confirmatory factor analyses were conducted in Mplus. The 7-factor hybrid model demonstrated good fit: CFI = .96, TLI = .95, RMSEA = .06 (90% CI [.05, .07]), SRMR = .03. This model was superior to the 5- and 6-factor models. All factors demonstrated significant relations with PA and NA, the largest of which were the Externalizing Behaviors (with NA) and Anhedonia (with PA) factors. Results provide support for the 7-factor hybrid model of PTSD using the PCL-5 in a community sample. Findings replicate previous research suggesting that PTSD is highly related to NA, which has been purported as an underlying dimension of PTSD. It is recommended that future research use clinical measures to further examine the hybrid model. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    The aim of the present study was to identify risk factors for community-acquired pneumonia (CAP), with special emphasis on modifiable risk factors and those applicable to the general population. A population-based, case-control study was conducted, with a target population of 859,033 inhabitants aged >14 yrs. A total of 1,336 patients with confirmed CAP were matched to control subjects by age, sex and primary centre over 1 yr. In the univariate analysis, outstanding risk factors were passive smoking in never-smokers aged >65 yrs, heavy alcohol intake, contact with pets, households with >10 people, contact with children, interventions on the upper airways and poor dental health. Risky treatments included amiodarone, N-acetylcysteine and oral steroids. Influenza and pneumococcal vaccine, and visiting the dentist were protective factors. Multivariable analysis confirmed cigarette smoking, usual contact with children, sudden changes of temperature at work, inhalation therapy (particularly containing steroids and using plastic pear-spacers), oxygen therapy, asthma and chronic bronchitis as independent risk factors. Interventions for reducing community-acquired pneumonia should integrate health habits and lifestyle factors related to household, work and community, together with individual clinical conditions, comorbidities and oral or inhaled regular treatments. Prevention would include vaccination, dental hygiene and avoidance of upper respiratory colonisation.

    2013-08-01

    community-based midwifery practice has been promoted in the UK maternity policy over the last decade as a means of increasing continuity of care. However, there have been growing concerns to suggest that the community-based continuity model may not be sustainable due to the high levels of occupational burnout in midwives resulted by increased on-call work. this paper attempted to identify work factors associated with the levels of burnout in community midwives as compared to hospital midwives, aiming at contributing to the debate of organising sustainable midwifery care. a statistical analysis was conducted drawing on data from a survey of all midwives working at one Hospital Trust in England (n=238). Occupational burnout was measured using the Maslach Burnout Inventory (MBI). the sample midwives (n=128, 54%) had significantly higher levels of burnout compared to the reference groups. Multiple regression analysis identified as follows: (1) high levels of occupational autonomy were a key protective factor of burnout, and more prevalent in the community, (2) working hours were positively associated with burnout, and community midwives were more likely to have higher levels of stress recognition, and (3) support for work-life-balance from the Trust had a significant protective effect on the levels of burnout. the results should be taken into account in the maternity policy in order to incorporate continuity of care and sustainable organisation of midwifery care.

    OBJECTIVES. The Minnesota Heart Health Program is a 13-year research and demonstration project to reduce morbidity and mortality from coronary heart disease in whole communities. METHODS. Three pairs of communities were matched on size and type; each pair had one education site and one comparison site. After baseline surveys, a 5- to 6-year program of mass media, community organization, and direct education for risk reduction was begun in the education communities, whereas surveys continued in all sites. RESULTS. Many intervention components proved effective in targeted groups. However, against a background of strong secular trends of increasing health promotion and declining risk factors, the overall program effects were modest in size and duration and generally within chance levels. CONCLUSIONS. These findings suggest that even such an intense program may not be able to generate enough additional exposure to risk reduction messages and activities in a large enough fraction of the population to accelerate the remarkably favorable secular trends in health promotion activities and in most coronary heart disease risk factors present in the study communities.

    The psychological effects of community violence exposure among inner-city youth are severe, yet little is known about its prevalence and moderators among suburban middle-class youth. This study aimed to assess the prevalence of community violence exposure among suburban American youth, to examine associated posttraumatic stress and to evaluate factors related to severe vs. less severe posttraumatic stress, such as co-existing internalizing and externalizing problems, as well as the effects of teacher support, parental warmth and support, perceived neighborhood safety and conventional involvement in this context. Data were collected from 780 suburban, predominantly Caucasian middle-class high-school adolescents in the Northeastern US during the Social and Health Assessment (SAHA) study. A substantial number of suburban youth were exposed to community violence and 24% of those victimized by community violence developed severe posttraumatic stress. Depressive symptoms were strongly associated with higher levels and perceived teacher support with lower levels of posttraumatic stress. Similar to urban youth, youth living in suburban areas in North American settings may be affected by community violence. A substantial proportion of these youth reports severe posttraumatic stress and high levels of comorbid depressive symptoms. Teacher support may have a protective effect against severe posttraumatic stress and thus needs to be further assessed as a potential factor that can be used to mitigate the detrimental effects of violence exposure.

    Although discrepancy in the specific traits and ecological characteristics of Bemisia tabaci between species are partially attributed to the B. tabaci-associated bacteria, the factors that affect the diversity of B. tabaci-associated bacteria are not well-understood. We used the metagenomic approach to characterize the B. tabaci-associated bacterial community because the approach is an effective tool to identify the bacteria. To investigate the effects of the host plant and a virus, tomato yellow leaf curl virus (TYLCV), on the bacterial communities of B. tabaci sibling species B and Q, we analyzed the bacterial communities associated with whitefly B and Q collected from healthy cotton, healthy tomato, and TYLCV-infected tomato. The analysis used miseq-based sequencing of a variable region of the bacterial 16S rDNA gene. For the bacteria associated with B. tabaci, we found that the influence of the host plant species was greater than that of the whitefly cryptic species. With further analysis of host plants infected with the TYLCV, the virus had no significant effects on the B. tabaci-associated bacterial community. The effects of different plant hosts and TYLCV-infection on the diversity of B. tabaci-associated bacterial communities were successfully analyzed in this study. To explain why B. tabaci sibling species with different host ranges differ in performance, the analysis of the bacterial community may be essential to the explanation.

    Dropping-out, which refers to when an individual abandons an intervention, is common in Internet-based studies as well as in online health communities. Community facilitators and health researchers are interested in this phenomenon because it usually indicates dissatisfaction towards the community and/or its failure to deliver expected benefits. In this study, we propose a method to identify dropout members from a large public online breast cancer community. We then study quantitatively what longitudinal factors of participation are correlated with dropping-out. Our experimental results suggest that dropout members discuss diagnosis- and treatment-related topics more than other topics. Furthermore, in the time before withdrawing from the community, dropout members tend to initiate more discussions but do not receive adequate response from the other members. We also discuss implications of our results and challenges in dropout-member identification. This study contributes to further understanding community participation and opens up a number of future research questions. PMID:28269969

    Estimates shows exclusive breastfeeding (EBF) has the potential to prevent 11.6% of all under-five deaths in developing countries. Prevalence of EBF is low globally (35%), and in sub Saharan Africa ranges between 22 and 33%. Like other developing countries the prevalence of EBF is 50% in Tanzania. There is limited information in Tanzania on factors influencing EBF apart from information specific for HIV positive women. This study aimed at examining factors that affect EBF practice among women in Muheza district, Tanga region, northeastern Tanzania. A community based cross-sectional study using both qualitative and quantitative methods was conducted from April to June 2014. To collect relevant information, a total of 316 women with infants aged 6-12 months were interviewed using a questionnaire and 12 key informants using in-depth interview guide. Qualitative data was analyzed using thematic analysis while bivariate and multivariate logistic regression analysis were used assess association between EBF and predictor variables. The prevalence of EBF was 24.1%. The perception that mothers' breast milk is insufficient for child's growth, child being thirsty and the need to introduce herbal medicine for cultural purposes were among the important factors for early mixed feeding. In multivariate analysis advanced maternal age (OR 2.6; 95% CI 1.18-5.59) and knowledge on EBF duration and advantages (OR 2.2; 95% CI 1.2-3.8) remained significantly associated with EBF practice. The prevalence of EBF in our study is low compared with the national prevalence. Strategies to target beliefs that breast milk is insufficient for growth need to be strengthened in the community. Furthermore opportunity to increase EBF training during ante and postnatal visits for women should be enhanced as more than 90% of women in the district use skilled attendants during pregnancy and delivery.

  12. The factors controlling species density in herbaceous plant communities: An assessment

    This paper evaluates both the ideas and empirical evidence pertaining to the control of species density in herbaceous plant communities. While most theoretical discussions of species density have emphasized the importance of habitat productivity and disturbance regimes, many other factors (e.g. species pools, plant litter accumulation, plant morphology) have been proposed to be important. A review of literature presenting observations on the density of species in small plots (in the vicinity of a few square meters or less), as well as experimental studies, suggests several generalizations: (1) Available data are consistent with an underlying unimodal relationship between species density and total community biomass. While variance in species density is often poorly explained by predictor variables, there is strong evidence that high levels of community biomass are antagonistic to high species density. (2) Community biomass is just one of several factors affecting variations in species density. Multivariate analyses typically explain more than twice as much variance in species density as can be explained by community biomass alone. (3) Disturbance has important and sometimes complex effects on species density. In general, the evidence is consistent with the intermediate disturbance hypothesis but exceptions exist and effects can be complex. (4) Gradients in the species pool can have important influences on patterns of species density. Evidence is mounting that a considerable amount of the observed variability in species density within a landscape or region may result from environmental effects on the species pool. (5) Several additional factors deserve greater consideration, including time lags, species composition, plant morphology, plant density and soil microbial effects. Based on the available evidence, a conceptual model of the primary factors controlling species density is presented here. This model suggests that species density is controlled by the effects of

    In contrast to adolescents attending traditional universities, adolescents attending community colleges represent a large but relatively unstudied population with respect to stress and mental health issues. The purpose of this study was to determine what factors increase and decrease stress in a sample of adolescent community college students (N = 166). Findings from a self-administered questionnaire indicated that students had moderate levels of stress and resilience. Contrary to predictions, males demonstrated statistically significant higher levels of stress than females, but as expected, resilience had a significant negative effect on stress (p < .05). Practice and research implications are discussed for nurses in pediatric settings.

    Worldwide, a shortage of skilled health workers has prompted a shift toward community-based health workers taking on greater responsibility in the provision of select maternal and newborn health services. Research in mid- and high-income settings suggests that coworker collaboration increases productivity and performance. A major gap in this research, however, is the exploration of factors that influence teamwork among diverse community health worker cadres in rural, low-resource settings. The purpose of this study is to examine how sociodemographic and structural factors shape teamwork among community-based maternal and newborn health workers in Ethiopia. A cross-sectional survey was conducted with health extension workers, community health development agents, and traditional birth attendants in 3 districts of the West Gojam Zone in the Amhara region of Ethiopia. Communities were randomly selected from Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) sites; health worker participants were recruited using a snowball sampling strategy. Fractional logit modeling and average marginal effects analyses were carried out to identify the influential factors for frequency of work interactions with each cadre. One hundred and ninety-four health workers participated in the study. A core set of factors-trust in coworkers, gender, and cadre-were influential for teamwork across groups. Greater geographic distance and perception of self-interested motivations were barriers to interactions with health extension workers, while greater food insecurity (a proxy for wealth) was associated with increased interactions with traditional birth attendants. Interventions that promote trust and gender sensitivity and improve perceptions of health worker motivations may help bridge the gap in health services delivery between low- and high-resource settings. Inter-cadre training may be one mechanism to increase trust and respect among diverse health workers, thereby increasing

    To examine the relevance of the International Classification of Functioning, Disability and Health (ICF) to CBR monitoring and evaluation by investigating the relationship between the ICF and information in published CBR monitoring and evaluation reports. A three-stage literature search and analysis method was employed. Studies were identified via online database searches for peer-reviewed journal articles, and hand-searching of CBR network resources, NGO websites and specific journals. From each study "information items" were extracted; extraction consistency among authors was established. Finally, the resulting information items were coded to ICF domains and categories, with consensus on coding being achieved. Thirty-six articles relating to monitoring and evaluating CBR were selected for analysis. Approximately one third of the 2495 information items identified in these articles (788 or 32%) related to concepts of functioning, disability and environment, and could be coded to the ICF. These information items were spread across the entire ICF classification with a concentration on Activities and Participation (49% of the 788 information items) and Environmental Factors (42%). The ICF is a relevant and potentially useful framework and classification, providing building blocks for the systematic recording of information pertaining to functioning and disability, for CBR monitoring and evaluation. Implications for Rehabilitation The application of the ICF, as one of the building blocks for CBR monitoring and evaluation, is a constructive step towards an evidence-base on the efficacy and outcomes of CBR programs. The ICF can be used to provide the infrastructure for functioning and disability information to inform service practitioners and enable national and international comparisons.

    Exploring processes of coevolution of microorganisms and their hosts is a new imperative for life sciences. If bacteria protect hosts against pathogens, mechanisms facilitating the intergenerational transmission of such bacteria will be strongly selected by evolution. By disentangling the diversity of bacterial strains from the uropygium of hoopoes (Upupa epops) due to genetic relatedness or to a common environment, we explored the importance of horizontal (from the environment) and vertical (from parents) acquisition of antimicrobial-producing symbionts in this species. For this purpose, we compared bacterial communities among individuals in nonmanipulated nests; we also performed a cross-fostering experiment using recently hatched nestlings before uropygial gland development and some nestlings that were reared outside hoopoe nests. The capacity of individuals to acquire microbial symbionts horizontally during their development was supported by our results, since cross-fostered nestlings share bacterial strains with foster siblings and nestlings that were not in contact with hoopoe adults or nests also developed the symbiosis. Moreover, nestlings could change some bacterial strains over the course of their stay in the nest, and adult females changed their bacterial community in different years. However, a low rate of vertical transmission was inferred, since genetic siblings reared in different nests shared more bacterial strains than they shared with unrelated nestlings raised in different nests. In conclusion, hoopoes are able to incorporate new symbionts from the environment during the development of the uropygium, which could be a selective advantage if strains with higher antimicrobial capacity are incorporated into the gland and could aid hosts in fighting against pathogenic and disease-causing microbes.

    This study examined interrelationships among community violence exposure, protective factors, and mental health in a sample of urban, predominantly African American adolescents (N = 504). Latent Profile Analysis was conducted to identify profiles of adolescents based on a combination of community violence exposure, self-worth, parental monitoring, and parental involvement and to examine whether these profiles differentially predict adolescents' depressive symptoms and aggressive behavior. Three classes were identified—a vulnerable class, a moderate risk/medium protection class, and a moderate risk/high protection class. The classes differentially predicted depressive symptoms but not aggressive behavior for boys and girls. The class with the highest community violence exposure also had the lowest self-worth.

    A population survey was conducted to explore the prevalence and factors associated with Leishmania infection in the Fercal region of the Federal District. The Fercal region is a group of neighborhoods in Brasília in which the first cases of visceral leishmaniasis were described. Leishmania infection was established by a positive leishmanin test. Although other tests were performed in the study (an immunochromatographic assay (Kalazar detect(®)) and a molecular assay), only the leishmanin skin test provided sufficient results for the measurement of the disease prevalence. Data on the epidemiological, clinical and environmental characteristics of individuals were collected along with the diagnostic tests. After sampling and enrollment, seven hundred people from 2 to 14 years of age were included in the study. The prevalence of Leishmania infection was 33.28% (95% CI 29.87-36.84). The factors associated with Leishmania infection according to the multivariate analysis were age of more than seven years and the presence of opossums near the home. Age is a known factor associated with Leishmania infection; however, the presence of wild animals, as described, is an understudied factor. The presence of opossums, which are known reservoirs of Leishmania, in peri-urban areas could be the link between the rural and urban occurrence of visceral leishmaniasis in the outskirts of largest Brazilian cities, as suggested by previous studies.

    Energy absorption geometric progression (GP) fitting parameters and the corresponding buildup factors have been computed for human organs and tissues, such as adipose tissue, blood (whole), cortical bone, brain (grey/white matter), breast tissue, eye lens, lung tissue, skeletal muscle, ovary, testis, soft tissue, and soft tissue (4-component), for the photon energy range 0.015-15 MeV and for penetration depths up to 40 mfp (mean free path). The chemical composition of human organs and tissues is seen to influence the energy absorption buildup factors. It is also found that the buildup factor of human organs and tissues changes significantly with the change of incident photon energy and effective atomic number, Z(eff). These changes are due to the dominance of different photon interaction processes in different energy regions and different chemical compositions of human organs and tissues. With the proper knowledge of buildup factors of human organs and tissues, energy absorption in the human body can be carefully controlled. The present results will help in estimating safe dose levels for radiotherapy patients and also useful in diagnostics and dosimetry. The tissue-equivalent materials for skeletal muscle, adipose tissue, cortical bone, and lung tissue are also discussed. It is observed that water and MS20 are good tissue equivalent materials for skeletal muscle in the extended energy range.

  5. Deriving amplification factors from simple site parameters using generalized regression neural networks: implications for relevant site proxies

    Most modern seismic codes account for site effects using an amplification factor (AF) that modifies the rock acceleration response spectra in relation to a "site condition proxy," i.e., a parameter related to the velocity profile at the site under consideration. Therefore, for practical purposes, it is interesting to identify the site parameters that best control the frequency-dependent shape of the AF. The goal of the present study is to provide a quantitative assessment of the performance of various site condition proxies to predict the main AF features, including the often used short- and mid-period amplification factors, Fa and Fv, proposed by Borcherdt (in Earthq Spectra 10:617-653, 1994). In this context, the linear, viscoelastic responses of a set of 858 actual soil columns from Japan, the USA, and Europe are computed for a set of 14 real accelerograms with varying frequency contents. The correlation between the corresponding site-specific average amplification factors and several site proxies (considered alone or as multiple combinations) is analyzed using the generalized regression neural network (GRNN). The performance of each site proxy combination is assessed through the variance reduction with respect to the initial amplification factor variability of the 858 profiles. Both the whole period range and specific short- and mid-period ranges associated with the Borcherdt factors Fa and Fv are considered. The actual amplification factor of an arbitrary soil profile is found to be satisfactorily approximated with a limited number of site proxies (4-6). As the usual code practice implies a lower number of site proxies (generally one, sometimes two), a sensitivity analysis is conducted to identify the "best performing" site parameters. The best one is the overall velocity contrast between underlying bedrock and minimum velocity in the soil column. Because these are the most difficult and expensive parameters to measure, especially for thick deposits, other

    During yearly meetings of the recently developed network of 15 public/community psychiatry fellowships, it has been noted that programs are having varying degrees of success with regard to recruitment. To understand factors that impact recruitment, a quality improvement survey of fellows and alumni was conducted. Respondents were asked to rate overall satisfaction with their fellowship training as well as perceived benefits and obstacles to participating in a fellowship program, and impact on their careers. A total of 155 (57%) fellows and alumni responded. Factor analysis was used to condense the variables, and a multiple regression explored factors predicting overall fellowship program satisfaction. Factors that represented perceived benefits had higher means than did factors that represent obstacles. Respondents highly valued the extent to which these fellowships enhanced their careers, with regard to job opportunities, academics, networking and leadership.

    Estuarine turbidity maxima (ETM) function as hotspots of microbial activity and diversity in estuaries, yet, little is known about the temporal and spatial variability in ETM bacterial community composition. To determine which environmental factors affect ETM bacterial populations in the Columbia River estuary, we analyzed ETM bacterial community composition (Sanger sequencing and amplicon pyrosequencing of 16S rRNA gene) and bulk heterotrophic production ((3) H-leucine incorporation rates). We collected water 20 times to cover five ETM events and obtained 42 samples characterized by different salinities, turbidities, seasons, coastal regimes (upwelling vs. downwelling), locations, and particle size. Spring and summer populations were distinct. All May samples had similar bacterial community composition despite having different salinities (1-24 PSU), but summer non-ETM bacteria separated into marine, freshwater, and brackish assemblages. Summer ETM bacterial communities varied depending on coastal upwelling or downwelling conditions and on the sampling site location with respect to tidal intrusion during the previous neap tide. In contrast to ETM, whole (>0.2 μm) and free-living (0.2-3 μm) assemblages of non-ETM waters were similar to each other, indicating that particle-attached (>3 μm) non-ETM bacteria do not develop a distinct community. Brackish water type (ETM or non-ETM) is thus a major factor affecting particle-attached bacterial communities. Heterotrophic production was higher in particle-attached than free-living fractions in all brackish waters collected throughout the water column during the rise to decline of turbidity through an ETM event (i.e., ETM-impacted waters). However, free-living communities showed higher productivity prior to or after an ETM event (i.e., non-ETM-impacted waters). This study has thus found that Columbia River ETM bacterial communities vary based on seasons, salinity, sampling location, and particle size, with the

The dominant species were Melosira varians, M. granulate, Cyclotella meneghiniana, Asterianella formosa, Synedra acus, Achnanthes exigua, Ankistrodesmus falcatus, Oscillatoria lacustris, Cryptomonas erosa, Chroomonas acuta, Phormidium tenue and Microcystis aeruginosa, etc. Seasonal variations of species were obvious. The annual abundance and biomass of the phytoplankton were 0.51 x 10(5)-14.22 x 10(5) ind x L(-1) and 0.07-1.27 mg x L(-1), respectively. The values of the Margelef index, Pielou index and Shannon index of the phytoplankton community were 1.10-3.33, 0.26-0.81 and 0.51-2.38, respectively. The phytoplankton community structure was of Bacillariophyta-Cryptophyta type in spring and winter, of Chlorophyta-Cyanophyta type in summer, and of Bacillariophyta type in autumn. Canonical correlation analysis (CCA) showed that temperature, transparency, chemical oxygen demand and pH had the closest relationships with the phytoplankton community structure in the reservoir. Water quality evaluation showed that Hengshan Reservoir was in a secondary pollution with a meso-trophic level.

    Community collaboration in research may lead to better methods, results, and dissemination of interventions. Little systematic research has examined specific factors that influence community-based organizations (CBOs) to collaborate in public health research. There is an urgent need to advance knowledge on this topic so that together, researchers and CBOs can minimize barriers to collaboration. This study advances a CBOfocused characterization of collaboration in HIV-prevention research. By focusing on the perspectives of 20 key informants in 10 HIV-prevention CBOs, qualitative data revealed factors that influenced their collaborations in four domains: (a) Researchers' Characteristics (expertise, availability), (b) Collaborative Research Characteristics (ought to improve services and CBO infrastructure); (c) Community Partner-Researcher Relationships (resolving social and professional issues); and (d) Barriers to HIV-Prevention Research Collaboration (cultural and social disconnect between CBO and academia). To reduce barriers, researchers ought to enhance motivators that facilitate collaboration. To use the advantages of community-based research, prevention scientists and policy makers ought to embrace CBOs' characterization of what makes health research genuinely collaborative.

    The rapidly evolving American health system creates economic and societal incentives for public and private health organizations to collaborate. Despite the apparent benefits of collaboration, there is a paucity of information available to help local agencies develop partnerships. This study, itself a collaboration between a school of public health (SPH) and a Georgia health district, was undertaken to identify critical factors necessary to successfully initiate and sustain a public/private community health collaboration. Professional staff at the SPH conducted 26 standardized interviews involving participants from Cobb and Douglas counties Boards of Health; Promina Northwest (now known as Wellstar), a not-for-profit health system; and community stakeholders. Content analysis of each interview question was performed and comparisons were made both within each group and across groups. Trends were identified in the following key areas: vision of health care for Cobb and Douglas counties, forces driving collaboration, strengths of each organization, critical negotiating issues, and potential community gain resulting from the partnership. A shared vision between potential collaborators facilitates communication regarding strategies to achieve common goals. A previous history of working together in limited capacities allowed the partners to develop trust and respect for one another prior to entering negotiations. These factors, when taken in conjunction with each organization's strong leadership and knowledge of the community, build a strong foundation for a successful partnership.

    Satisfaction of communities living close to forests with forest management authorities is essential for ensuring continued support for conservation efforts. However, more often than not, community satisfaction is not systematically elicited, analyzed, and incorporated in conservation decisions. This study attempts to elicit levels of community satisfaction with three management approaches of Kakamega forest in Kenya and analyze factors influencing them. Three distinct management approaches are applied by three different authorities: an incentive-based approach of the Forest Department (FD), a protectionist approach of the Kenya Wildlife Service (KWS), and a quasi-private incentive-based approach of Quakers Church Mission (QCM). Data was obtained from a random sample of about 360 households living within a 10-km radius around the forest margin. The protectionist approach was ranked highest overall for its performance in forest management. Results indicate that households are influenced by different factors in their ranking of management approaches. Educated households and those located far from market centers are likely to be dissatisfied with all the three management approaches. The location of the households from the forest margin influences negatively the satisfaction with the protectionist approach, whereas land size, a proxy for durable assets, has a similar effect on the private incentive based approach of the QCM. In conclusion, this article indicates a number of policy implications that can enable the different authorities and their management approaches to gain approval of the local communities.

    The objective of this study was to assess the role performance among KOSPEN community health volunteer in Kuching district and its associated factors. This was a cross-sectional study, conducted in 21 localities in Kuching with a total of 210 respondents. Data were collected using validated interviewer-administered questionnaires and analyzed using SPSS version 22.0. The respondents comprised 55.2% females, 81.9% married, and 41.4% aged above 45 and above and 72.4% completed their education up to secondary school. The result revealed that 59.0% of the respondents agreed and understood their role performances. Multiple Logistics analysis revealed that factors associated with role performance were age group (p = 0.003), education level (p < 0.001), marital status (p = 0.025), prestige and respect (p = 0.012), being seen as "doctor" in community (p = 0.003), job aids (p = 0.009), training location (p = 0.001), and supervision by community (p < 0.001). To increase and maintain the work performance of CHVs, commitment from the government, policy makers, stakeholders, and the communities is required.

    Nearly 3500 people under 60 years of age are living in residential aged care in Australia, a situation which is generally recognized as incompatible with optimum quality of life. The objective of the current study is to explore the transition experiences of young people with acquired brain injury who have lived in aged care facilities and moved into community-based settings. Grounded theory, qualitative design. Semi-structured interviews were conducted with seven individuals with very severe ABI, seven family caregivers and two disability support workers. Each interview was recorded and transcribed verbatim. Participants identified a range of positive outcomes that resulted from the transition from aged care settings to community living environments including increased independence in everyday activities, improved well-being and a greater degree of social inclusion. Participants also identified environmental factors that they deemed as crucial to facilitating positive outcomes. People with very severe ABI have the potential to increase their level of independence in community-based accommodation settings; a potential that is not fostered in most aged care environments. The findings inform the outcome variables and environmental factors that should be measured in studies of transition from aged care to the community.

    Despite the availability of numerous obesity prevention initiatives in developed countries including Australia, rising childhood obesity levels have been found among migrant communities which contribute to widening obesity-related disparities in these countries. We sought to understand the factors influencing the participation of migrant communities in childhood obesity prevention initiatives. We conducted a qualitative study using semi-structured interviews among 48 migrant parents from African, Middle Eastern, Indian and Vietnamese origins living in disadvantaged areas of Victoria, Australia to explore their views on childhood obesity and its prevention. Thematic analysis showed low obesity literacy among migrant communities, cultural influences negatively impacting their healthy lifestyle behaviours and cultural, family-level and community-level barriers impacting their participation in childhood obesity prevention initiatives. There is an urgent need to improve obesity literacy among migrant communities using bicultural workers in order to improve their responsiveness to childhood obesity prevention initiatives. Health interventionists are urged to incorporate culturally-mediated influences in the design of obesity prevention programs to achieve energy balance and maintain healthy weight among migrants. Such culturally appropriate approaches have the potential of reducing the widening ethnic-related obesity disparities in Australia.

    Bacteria play a critical role in environmental and ecological processes in river ecosystems. We studied the bacterial community in the Ganjiang River, a major tributary of the Yangtze River, as it flowed through Nanchang, the largest city in the Ganjiang River basin. Water was sampled at five sites monthly during the wet season, and the bacterial community was characterized using Illumina high-throughput sequencing. A total of 811 operational taxonomic units (OTUs) were observed for all samples, ranging from 321 to 519 for each sample. The bacterial communities were maintained by a core of OTUs that persisted longitudinally and monthly. Actinobacteria (41.17% of total sequences) and Proteobacteria (31.80%) were the dominant phyla, while Firmicutes (mostly genus Lactococcus) became most abundant during flooding. Temperature and flow rate, rather than water chemistry, were the main factors influencing the bacterial community in river water. Temperature was the best individual parameter explaining the variations in OTU abundance, while flow rate was the best individual parameter explaining the variations in phylum abundance. Except for Proteobacteria, the relative abundance of bacterial phyla did not differ significantly between sites, and the degrees of influence of urban landscape on the bacterial community were estimated to be 17%-34%.

    Community detection is a meaningful task in the analysis of complex networks, which has received great concern in various domains. A plethora of exhaustive studies has made great effort and proposed many methods on community detection. Particularly, a kind of attractive one is the two-step method which first makes a preprocessing for the network and then identifies its communities. However, not all types of methods can achieve satisfactory results by using such preprocessing strategy, such as the non-negative matrix factorization (NMF) methods. In this paper, rather than using the above two-step method as most works did, we propose a graph regularized-based model to improve, specialized, the NMF-based methods for the detection of communities, namely NMFGR. In NMFGR, we introduce the similarity metric which contains both the global and local information of networks, to reflect the relationships between two nodes, so as to improve the accuracy of community detection. Experimental results on both artificial and real-world networks demonstrate the superior performance of NMFGR to some competing methods.
