  1. Ansel Adams: early works

    2010-02-01

    Ansel Adams (1902-1984), photographer, musician, naturalist, explorer, critic, and teacher, was a giant in the field of landscape photography. In his images of the unspoiled Western landscape, he strove to capture the sublime: the transcendentalist concept that nature can generate the experience of awe for the viewer. Many viewers are familiar with the heroic, high-contrast prints on high-gloss paper that Adams made to order beginning in the 1970s; much less well known are the intimate prints that the artist crafted earlier in his career. This exhibition focuses on these masterful small prints from the 1920s into the 1950s. During this time period, Adams's printing style changed dramatically. The painterly, soft-focus, warm-toned style of the Parmelian Prints of the High Sierras from the 1920s evolved into the sharp-focus style of the f/64 school of photography that Adams co-founded in the 1930s with Edward Weston and Imogen Cunningham. After World War II, Adams opted for a cooler, higher-contrast look for his prints. Throughout the various styles in which he chose to work, Adams explored the power of nature and succeeded in establishing landscape photography as a legitimate form of modern art.

    Ecosystems on the verge of major reorganization—regime shift—may exhibit declining resilience, which can be detected using a collection of generic statistical tests known as early warning signals (EWSs). This study explores whether EWSs anticipated human population collapse during the European Neolithic. It analyzes recent reconstructions of European Neolithic (8–4 kya) population trends that reveal regime shifts from a period of rapid growth following the introduction of agriculture to a period of instability and collapse. We find statistical support for EWSs in advance of population collapse. Seven of nine regional datasets exhibit increasing autocorrelation and variance leading up to collapse, suggesting that these societies began to recover from perturbation more slowly as resilience declined. We derive EWS statistics from a prehistoric population proxy based on summed archaeological radiocarbon date probability densities. We use simulation to validate our methods and show that sampling biases, atmospheric effects, radiocarbon calibration error, and taphonomic processes are unlikely to explain the observed EWS patterns. The implications of these results for understanding the dynamics of Neolithic ecosystems are discussed, and we present a general framework for analyzing societal regime shifts using EWS at large spatial and temporal scales. We suggest that our findings are consistent with an adaptive cycling model that highlights both the vulnerability and resilience of early European populations. We close by discussing the implications of the detection of EWS in human systems for archaeology and sustainability science. PMID:27573833

    Los Alamos scientists have advanced a Magnetic Resonance Imaging (MRI) technology that may provide a breakthrough for screening liquids at airport security. They've added low-power X-ray data to the mix, and as a result have unlocked a new detection technology. Funded in part by the Department of Homeland Security's Science and Technology Directorate, the new system is named MagRay. The goal is to quickly and accurately distinguish between liquids that visually appear identical. For example, what appears to be a bottle of white wine could potentially be nitromethane, a liquid that could be used to make an explosive. Both are clear liquids, one would be perfectly safe on a commercial aircraft, the other would be strictly prohibited. How to tell them apart quickly without error at an airport security area is the focus of Michelle Espy, Larry Schultz and their team. In this video, Espy and the MagRay team explain how the new technology works, how they've developed an easy operator interface, and what the next steps might be in transitioning this technology to the private sector.

  15. Differences in Trait Impulsivity Indicate Diversification of Dog Breeds into Working and Show Lines.

    PubMed

    Fadel, Fernanda Ruiz; Driscoll, Patricia; Pilot, Malgorzata; Wright, Hannah; Zulch, Helen; Mills, Daniel

    2016-03-10

    Impulsiveness describes the inability to inhibit behaviour in the presence of salient cues. Trait-level impulsivity exists on a continuum and individual differences can be adaptive in different contexts. While breed related differences in behavioural tendency in the domestic dog (Canis familiaris) are well established, the phenomenon within lines of a breed which have been selected more recently is not well studied, although it may challenge the popular notion of breed-typical behaviour. We describe differences in impulsivity between and within two dog breeds with working and show lines selected for different levels of impulsivity: Border Collies (herding work) and Labrador Retrievers (gun work). Recent show line selection might have lessened differences in impulsivity between breeds. We tested this hypothesis on a dataset of 1161 individuals assessed using a validated psychometric tool (Dog Impulsivity Assessment Scale--DIAS). Collies were more impulsive on average, consistent with the original purpose of breed selection. Regarding line, working Collies differed from working Labradors, but show lines from the two breeds were not significantly different. Altered or relaxed artificial selection for behavioural traits when appearance rather than behaviour become the primary focus for breeders may reduce average differences in impulsivity between breeds in show lines.

    2014-02-01

    The main aim of this study was to compare two days of continuous monitored capillary blood glucose (CGM) responses to sitting and standing in normally desk-based workers. This open repeated-measures study took place in a real office environment, during normal working hours and subsequent CGM overnight measures in 10 participants aged 21-61 years (8 female). Postprandial (lunch) measures of: CGM, accelerometer movement counts (MC) heart rate, energy expenditure (EE) and overnight CGM following one afternoon of normal sitting work compared with one afternoon of the same work performed at a standing desk. Area-under-the-curve analysis revealed an attenuated blood glucose excursion by 43% (p=0.022) following 185 min of standing (143, 95% CI 5.09 to 281.46 mmol/L min) compared to sitting work (326; 95% CI 228 to 425 mmol/L min). Compared to sitting, EE during an afternoon of standing work was 174 kcals greater (0.83 kcals/min; p=0.028). The accelerometer MC showed no differences between the afternoons of seated versus standing work; reported differences were thus a function of the standing work and not from additional physical movements around the office. This is the first known 'office-based' study to provide CGM measures that add some of the needed mechanistic information to the existing evidence-base on why avoiding sedentary behaviour at work could lead to a reduced risk of cardiometabolic diseases.

    2017-09-09

    Objective The Work Role Functioning Questionnaire v2.0 (WRFQ) is an outcome measure linking a persons' health to the ability to meet work demands in the twenty-first century. We aimed to examine the construct validity of the WRFQ in a heterogeneous set of working samples in the Netherlands with mixed clinical conditions and job types to evaluate the comparability of the scale structure. Methods Confirmatory factor and multi-group analyses were conducted in six cross-sectional working samples (total N = 2433) to evaluate and compare a five-factor model structure of the WRFQ (work scheduling demands, output demands, physical demands, mental and social demands, and flexibility demands). Model fit indices were calculated based on RMSEA ≤ 0.08 and CFI ≥ 0.95. After fitting the five-factor model, the multidimensional structure of the instrument was evaluated across samples using a second order factor model. Results The factor structure was robust across samples and a multi-group model had adequate fit (RMSEA = 0.63, CFI = 0.972). In sample specific analyses, minor modifications were necessary in three samples (final RMSEA 0.055-0.080, final CFI between 0.955 and 0.989). Applying the previous first order specifications, a second order factor model had adequate fit in all samples. Conclusion A five-factor model of the WRFQ showed consistent structural validity across samples. A second order factor model showed adequate fit, but the second order factor loadings varied across samples. Therefore subscale scores are recommended to compare across different clinical and working samples.

  20. Cardiac action potential repolarization revisited: early repolarization shows all-or-none behaviour.

    PubMed

    Trenor, Beatriz; Cardona, Karen; Saiz, Javier; Noble, Denis; Giles, Wayne

    2017-11-01

    In healthy mammalian hearts the action potential (AP) waveform initiates and modulates each contraction, or heartbeat. As a result, AP height and duration are key physiological variables. In addition, rate-dependent changes in ventricular AP duration (APD), and variations in APD at a fixed heart rate are both reliable biomarkers of electrophysiological stability. Present guidelines for the likelihood that candidate drugs will increase arrhythmias rely on small changes in APD and Q-T intervals as criteria for safety pharmacology decisions. However, both of these measurements correspond to the final repolarization of the AP. Emerging clinical evidence draws attention to the early repolarization phase of the action potential (and the J-wave of the ECG) as an additional important biomarker for arrhythmogenesis. Here we provide a mechanistic background to this early repolarization syndrome by summarizing the evidence that both the initial depolarization and repolarization phases of the cardiac action potential can exhibit distinct time- and voltage-dependent thresholds, and also demonstrating that both can show regenerative all-or-none behaviour. An important consequence of this is that not all of the dynamics of action potential repolarization in human ventricle can be captured by data from single myocytes when these results are expressed as 'repolarization reserve'. For example, the complex pattern of cell-to-cell current flow that is responsible for AP conduction (propagation) within the mammalian myocardium can change APD and the Q-T interval of the electrocardiogram alter APD stability, and modulate responsiveness to pharmacological agents (such as Class III anti-arrhythmic drugs). © 2017 The Authors.

    2014-01-01

    Recent data suggest that early symptoms may be related to cortex alterations in CADASIL (Cerebral Autosomal-Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), a monogenic model of cerebral small vessel disease (SVD). The aim of this study was to investigate cortical alterations using both high-resolution T2* acquisitions obtained with 7 Tesla MRI and structural T1 images with 3 Tesla MRI in CADASIL patients with no or only mild symptomatology (modified Rankin's scale ≤1 and Mini Mental State Examination (MMSE) ≥24). Complete reconstructions of the cortex using 7 Tesla T2* acquisitions with 0.7 mm isotropic resolution were obtained in 11 patients (52.1±13.2 years, 36% male) and 24 controls (54.8±11.0 years, 42% male). Seven Tesla T2* within the cortex and cortical thickness and morphology obtained from 3 Tesla images were compared between CADASIL and control subjects using general linear models. MMSE, brain volume, cortical thickness and global sulcal morphology did not differ between groups. By contrast, T2* measured by 7 Tesla MRI was significantly increased in frontal, parietal, occipital and cingulate cortices in patients after correction for multiple testing. These changes were not related to white matter lesions, lacunes or microhemorrhages in patients having no brain atrophy compared to controls. Seven Tesla MRI, by contrast to state of the art post-processing of 3 Tesla acquisitions, shows diffuse T2* alterations within the cortical mantle in CADASIL whose origin remains to be determined.

    Background Anxiety patients exhibit deficits in cognitive tasks that require prefrontal control of attention, including those that tap working memory (WM). However, it is unclear whether these deficits reflect threat-related processes or symptoms of the disorder. Here we distinguish between these hypotheses by determining the effect of shock threat vs. safety on the neural substrates of WM performance in anxiety patients and healthy controls. Methods Patients, diagnosed with generalized and/or social anxiety disorder, and controls performed blocks of an N-back WM task during periods of safety and threat of shock. We recorded BOLD activity during the task, and investigated the effect of clinical anxiety (patients vs. controls) and threat on WM load-related BOLD activation. Results Behaviorally, patients showed an overall impairment in both accuracy and reaction time compared to controls, independent of threat. At the neural level, patients showed less WM load-related activation in the dorsolateral prefrontal cortex, a region critical for cognitive control. In addition, patients showed less WM load-related deactivation in the ventromedial prefrontal cortex and posterior cingulate cortex, which are regions of the default mode network. Most importantly, these effects were not modulated by threat. Conclusions This work suggests that the cognitive deficits seen in anxiety patients may represent a key component of clinical anxiety, rather than a consequence of threat. PMID:27110997

    Parkinson's disease (PD) occurs in both familial and sporadic forms, and both monogenic and complex genetic factors have been identified. Early onset PD (EOPD) is particularly associated with autosomal recessive (AR) mutations, and three genes, PARK2, PARK7 and PINK1, have been found to carry mutations leading to AR disease. Since mutations in these genes account for less than 10% of EOPD patients, we hypothesized that further recessive genetic factors are involved in this disorder, which may appear in extended runs of homozygosity. We carried out genome wide SNP genotyping to look for extended runs of homozygosity (ROHs) in 1,445 EOPD cases and 6,987 controls. Logistic regression analyses showed an increased level of genomic homozygosity in EOPD cases compared to controls. These differences are larger for ROH of 9 Mb and above, where there is a more than three-fold increase in the proportion of cases carrying a ROH. These differences are not explained by occult recessive mutations at existing loci. Controlling for genome wide homozygosity in logistic regression analyses increased the differences between cases and controls, indicating that in EOPD cases ROHs do not simply relate to genome wide measures of inbreeding. Homozygosity at a locus on chromosome19p13.3 was identified as being more common in EOPD cases as compared to controls. Sequencing analysis of genes and predicted transcripts within this locus failed to identify a novel mutation causing EOPD in our cohort. There is an increased rate of genome wide homozygosity in EOPD, as measured by an increase in ROHs. These ROHs are a signature of inbreeding and do not necessarily harbour disease-causing genetic variants. Although there might be other regions of interest apart from chromosome 19p13.3, we lack the power to detect them with this analysis. PMID:22427796

    Background and Purpose Recent data suggest that early symptoms may be related to cortex alterations in CADASIL (Cerebral Autosomal-Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy), a monogenic model of cerebral small vessel disease (SVD). The aim of this study was to investigate cortical alterations using both high-resolution T2* acquisitions obtained with 7 Tesla MRI and structural T1 images with 3 Tesla MRI in CADASIL patients with no or only mild symptomatology (modified Rankin’s scale ≤1 and Mini Mental State Examination (MMSE) ≥24). Methods Complete reconstructions of the cortex using 7 Tesla T2* acquisitions with 0.7 mm isotropic resolution were obtained in 11 patients (52.1±13.2 years, 36% male) and 24 controls (54.8±11.0 years, 42% male). Seven Tesla T2* within the cortex and cortical thickness and morphology obtained from 3 Tesla images were compared between CADASIL and control subjects using general linear models. Results MMSE, brain volume, cortical thickness and global sulcal morphology did not differ between groups. By contrast, T2* measured by 7 Tesla MRI was significantly increased in frontal, parietal, occipital and cingulate cortices in patients after correction for multiple testing. These changes were not related to white matter lesions, lacunes or microhemorrhages in patients having no brain atrophy compared to controls. Conclusions Seven Tesla MRI, by contrast to state of the art post-processing of 3 Tesla acquisitions, shows diffuse T2* alterations within the cortical mantle in CADASIL whose origin remains to be determined.

    1999-01-01

    Risk of early exit from work for teachers was operationalized as high burnout scores, working part-time due to heavy burden and illness or working part-time while also receiving partial disability pension. Data were collected by mailed questionnaires in a cross-sectional study to a random sample of Norwegian comprehensive schoolteachers, response rate = 86% (N = 1860 valid cases). High age increased the risk of early exit from work, but for cynicism the age effect disappeared when sense of competence and stress were introduced in the regression model. Age had no effect for low professional efficacy. Sense of competence effected burnout, but actual competence level and the gap between actual competence and teaching obligations did not. Stress effected all measures of risk of early exit, especially exhaustion. Change as stress factor increased the exhaustion scores, and were also relevant to risk of having a part-time position, and/or partial disability pension.

    Previous research indicates that work modifications can effectively enhance return to work (RTW) at an early stage of work disability. We aimed to examine how occupational physicians (OPs) reason about recommending early return to work (RTW) with work modifications. Pre-defined propositions regarding the use of work modifications in promoting early RTW were discussed in four focus groups with altogether 11 Finnish OPs. Discussions were audio recorded, and the transcribed data were analyzed using qualitative content analysis. Five different rationales for supporting early RTW were identified: to manage medical conditions, to enhance employee well-being, to help workplace stakeholders, to reduce costs to society, and to enhance OP’s own professional fulfillment. However, OPs identified situations and conditions in which early RTW may not be suitable. In addition, there were differences between the OPs in the interpretation of the rationales, suggesting variation in clinical practice. In conclusion, encouraging early RTW with work modifications was perceived by OPs as a meaningful task and, to a large extent, beneficial for employees and several stakeholders. However, this practice was not accepted without consideration to the RTW situation and context. If early RTW and work modifications are to be promoted, OPs should be offered education that addresses their views regarding this practice. PMID:27367908

  10. Early blindness alters the spatial organization of verbal working memory.

    Several studies suggest that serial order in working memory (WM) is grounded on space. For a list of ordered items held in WM, items at the beginning of the list are associated with the left side of space and items at the end of the list with the right side. This suggests that maintaining items in verbal WM is performed in strong analogy to writing these items down on a physical whiteboard for later consultation (The Mental Whiteboard Hypothesis). What drives this spatial mapping of ordered series in WM remains poorly understood. In the present study we tested whether visual experience is instrumental in establishing the link between serial order in WM and spatial processing. We tested early blind (EB), late blind (LB) and sighted individuals in an auditory WM task. Replicating previous studies, left-key responses were faster for early items in the list whereas later items facilitated right-key responses in the sighted group. The same effect was observed in LB individuals. In contrast, EB participants did not show any association between space and serial position in WM. These results suggest that early visual experience plays a critical role in linking ordered items in WM and spatial representations. The analogical spatial structure of WM may depend in part on the actual experience of using spatially organized devices (e.g., notes, whiteboards) to offload WM. These practices are largely precluded to EB individuals, who instead rely to mnemonic devices that are less spatially organized (e.g., recordings, vocal notes). The way we habitually organize information in the external world may bias the way we organize information in our WM. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Information technology (IT) systems have been described as brittle and prone to automation surprises. Recent report of information system failure, particularly computerized physician order entry (CPOE) systems, shows the result of IT failure in actual practice. Such mismatches with healthcare work requirements necessitate improvement to IT research and development. Efforts to develop successful IT systems for healthcare’s sharp end must incorporate properties that reflect workers’ initiative in respose to domain constraints. Resilience is the feature of some systems that makes it possible for them to respond to sudden, unanticipated demands for performance and return to normal operation quickly, with minimum decrement in performance. Workers create resilience at healthcare’s sharp end by daily confronting constraints and obstacles that need to be surmounted in order to accomplish results. The sign-out sheet is an example of resilience that can be used to guide IT development. PMID:17238408

    Background Colorectal cancer is an emerging problem in cystic fibrosis (CF). The goal of this study was to evaluate adenoma detection by systematic colonoscopic screening and surveillance. Methods We analyzed prospectively collected results of colonoscopies initiated at age 40 years from 88 CF patients at a single Cystic Fibrosis Center. We also reviewed results of diagnostic colonoscopies from 27 patients aged 30–39 years performed during the same time period at the Center. Results The incidence of polyp detection increased markedly after age 40 in CF patients. Greater than 50% were found to have adenomatous polyps; approximately 25% had advanced adenomas as defined by size and/or histopathology; 3% were found to have colon cancer. Multivariate analysis demonstrated specific risk factors for adenoma formation and progression. Conclusions Early screening and more frequent surveillance should be considered in patients with CF due to early incidence and progression of adenomas in this patient population. PMID:26851188

    A child's ability to continuously pay attention to a cognitive task is often challenged by distracting events. Distraction is especially detrimental in a learning or classroom environment in which attended information is typically associated with establishing skills and knowledge. Here we report a study examining the effect of emotional distractors on performance in a subsequent visual lexical decision task in 11- to 13-year-old students (n=30). Lexical decisions about neutral verbs and verb-like pseudowords (i.e., targets) were analysed as a function of the preceding distractor type (pleasant, neutral, or unpleasant photos) and the picture-target stimulus-onset asynchrony (SOA; 200 or 600 ms). Across distractor categories, emotionally arousing pictures prolonged decisions about word targets when compared to neutral pictures, irrespective of the SOA. The present results demonstrate that similar to adults, early adolescent students exhibit sustained susceptibility to cognitive interference by irrelevant emotional events.

    Nutrient acquisition of forest stands is controlled by soil resource availability and belowground production, but tree species are rarely compared in this regard. Here, we examine ecological and management implications of nitrogen (N) dynamics during early forest stand development in productive commercial tree species with narrow (Populus deltoides Bartr. and Platanus occidentalis L.) and broad (Liquidambar styraciflua L. and Pinus taeda L.) site requirements while grown with a range of nutrient and water resources. We constructed N budgets by measuring N concentration ([N]) and N content (N{sub C}) of above- and belowground perennial and ephemeral tissues, determined N uptake (N{submore » UP}), and calculated N use efficiency (NUE). Forest stands regulated [N] within species-specific operating ranges without clear temporal or treatment patterns, thus demonstrating equilibrium between tissue [N] and biomass accumulation. Forest stand N{sub C} and N{sub UP} increased with stand development and paralleled treatment patterns of biomass accumulation, suggesting productivity is tightly linked to N{sub UP}. Inclusion of above- and belowground ephemeral tissue turnover in N{sub UP} calculations demonstrated that maximum N demand for narrow-sites adapted species exceeded 200 kg N ha{sup -1} year{sup -1} while demand for broad-site adapted species was below this level. NUE was species dependent but not consistently influenced by N availability, suggesting relationships between NUE and resource availability were species dependent. Based on early stand development, species with broad site adaptability are favored for woody cropping systems because they maintain high above- and belowground productivity with minimal fertilization requirements due to higher NUE than narrow site adapted species.« less

  1. Why Japanese workers show low work engagement: An item response theory analysis of the Utrecht Work Engagement scale

    PubMed Central

    2010-01-01

    With the globalization of occupational health psychology, more and more researchers are interested in applying employee well-being like work engagement (i.e., a positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and absorption) to diverse populations. Accurate measurement contributes to our further understanding and to the generalizability of the concept of work engagement across different cultures. The present study investigated the measurement accuracy of the Japanese and the original Dutch versions of the Utrecht Work Engagement Scale (9-item version, UWES-9) and the comparability of this scale between both countries. Item Response Theory (IRT) was applied to the data from Japan (N = 2,339) and the Netherlands (N = 13,406). Reliability of the scale was evaluated at various levels of the latent trait (i.e., work engagement) based the test information function (TIF) and the standard error of measurement (SEM). The Japanese version had difficulty in differentiating respondents with extremely low work engagement, whereas the original Dutch version had difficulty in differentiating respondents with high work engagement. The measurement accuracy of both versions was not similar. Suppression of positive affect among Japanese people and self-enhancement (the general sensitivity to positive self-relevant information) among Dutch people may have caused decreased measurement accuracy. Hence, we should be cautious when interpreting low engagement scores among Japanese as well as high engagement scores among western employees. PMID:21054839

    The aim of this study was to identify the core competencies required of mental health professionals working in the early psychosis field, which could function as an evidence-based tool to support the early psychosis workforce and in turn assist early psychosis service implementation and strengthen early psychosis model fidelity. The Delphi method was used to establish expert consensus on the core competencies. In the first stage, a systematic literature search was conducted to generate competency items. In the second stage, a panel consisting of expert early psychosis clinicians from around the world was formed. Panel members then rated each of the competency items on how essential they are to the clinical practice of all early psychosis clinicians. In total, 1023 pieces of literature including textbooks, journal articles and grey literature were reviewed. A final 542 competency items were identified for inclusion in the questionnaire. A total of 63 early psychosis experts participated in 3 rating rounds. Of the 542 competency items, 242 were endorsed as the required core competencies. There were 29 competency items that were endorsed by 62 or more experts, and these may be considered the foundational competencies for early psychosis practice. The study generated a set of core competencies that provide a common language for early psychosis clinicians across professional disciplines and country of practice, and potentially are a useful professional resource to support early psychosis workforce development and service reform. © 2017 John Wiley & Sons Australia, Ltd.

    This study investigated the relationship between fatigue and work safety behavior of fathers with new babies. A total of 241 fathers completed a questionnaire at 6 and 12 weeks postpartum with items on fatigue and safety behavior at work. Results revealed that fathers worked long hours, reported a moderate-to-high physical intensity of work, and experienced interrupted sleep averaging less than 6 hours. Fathers also reported moderate fatigue at both 6 and 12 weeks postbirth, which was inversely related to safety behavior. Both fatigue and sleep history made a small but statistically significant contribution to safety behavior results at 6 and 12 weeks postbirth. Findings suggest that working fathers with babies experience fatigue during early fatherhood and are unable to recover due to interrupted and poor sleep patterns. Managers should consider the potential for fatigue to compromise work safety and develop risk management strategies that target new fathers.

    Breast cancer patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse earlier than others. In addition, some tumor clones respond to immunotherapy while others do not. We investigated how autophagy plays a role in accelerating or delaying recurrence of neu-overexpressing mouse mammary carcinoma (MMC) following adriamycin (ADR) treatment, and in affecting response to immunotherapy. We explored two strategies: 1) transient blockade of autophagy with chloroquine (CQ), which blocks fusion of autophagosomes and lysosomes during ADR treatment, and 2) permanent inhibition of autophagy by a stable knockdown of ATG5 (ATG5KD), which inhibits the formation of autophagosomes in MMC during and after ADR treatment. We found that while CQ prolonged tumor dormancy, but that stable knockdown of autophagy resulted in early escape from dormancy and recurrence. Interestingly, ATG5KD MMC contained an increased frequency of ADR-induced polyploid-like cells and rendered MMC resistant to immunotherapy. On the other hand, a transient blockade of autophagy did not affect the sensitivity of MMC to immunotherapy. Our observations suggest that while chemotherapy-induced autophagy may facilitate tumor relapse, cell-intrinsic autophagy delays tumor relapse, in part, by inhibiting the formation of polyploid-like tumor dormancy.

    Initially, human area MT+ was considered a visual area solely processing motion information but further research has shown that it is also involved in various different cognitive operations, such as working memory tasks requiring motion-related information to be maintained or cognitive tasks with implied or expected motion.In the present fMRI study in humans, we focused on MT+ modulation during working memory maintenance using a dynamic shape-tracking working memory task with no motion-related working memory content. Working memory load was systematically varied using complex and simple stimulus material and parametrically increasing retention periods. Activation patterns for the difference between retention of complex and simple memorized stimuli were examined in order to preclude that the reported effects are caused by differences in retrieval. Conjunction analysis over all delay durations for the maintenance of complex versus simple stimuli demonstrated a wide-spread activation pattern. Percent signal change (PSC) in area MT+ revealed a pattern with higher values for the maintenance of complex shapes compared to the retention of a simple circle and with higher values for increasing delay durations. The present data extend previous knowledge by demonstrating that visual area MT+ presents a brain activity pattern usually found in brain regions that are actively involved in working memory maintenance.

    Inflammatory arthritis is associated with a high degree of work instability and financial burden. In this study, we examine the extent of work instability and financial loss as well as their association with disease characteristics during the first 18 months of inflammatory arthritis. One hundred and four patients in the early phase (more than 6 weeks, < 18 months) of inflammatory arthritis were recruited from a larger early inflammatory arthritis registry. Questionnaires recorded sociodemographic data and disease characteristics, including pain assessed using the Short Form McGill Pain Questionnaire (MPQ) and physical functioning measured with the Medical Outcomes Study Short Form 36 (SF-36) physical functioning score. The Rheumatoid Arthritis Work Instability Scale (RA-WIS) was used to measure patient-perceived functioning in the workplace and the Financial Loss Questionnaire (FLQ) measured the impact on family finances. Participants' mean age was 56 years, 70.2% were female and 49.0% were working. Average yearly household income was < 60 000 Canadian dollars (CAD) for 38.5% of the sample. Of our working patients, 43% had a medium or high risk of work loss as measured by the RA-WIS and 35% reported a financial loss. On multivariate analysis, MPQ and SF-36 contributed to the dependent variable work instability, while age and SF-36 contributed to financial loss. This study identifies pain and physical dysfunction as potential modifiable risk factors for negative socioeconomic repercussions of illness in early inflammatory arthritis. © 2012 The Authors International Journal of Rheumatic Diseases © 2012 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    2014-01-01

    Working memory is important for mental reasoning and learning processes. Several studies in adults and school-age children have shown performance improvement in cognitive tests after working memory training. Our aim was to examine not only immediate but also long-term effects of intensive working memory training on cognitive performance tests in children. Fourteen healthy male subjects between 10 and 16 years trained a visuospatial n-back task over 3 weeks (30 min daily), while 15 individuals of the same age range served as a passive control group. Significant differences in immediate (after 3 weeks of training) and long-term effects (after 2-6 months) in an auditory n-back task were observed compared to controls (2.5 fold immediate and 4.7 fold long-term increase in the training group compared to the controls). The improvement was more pronounced in subjects who improved their performance during the training. Other cognitive functions (matrices test and Stroop task) did not change when comparing the training group to the control group. We conclude that visuospatial working memory training in children boosts performance in similar memory tasks such as the auditory n-back task. The sustained performance improvement several months after the training supports the effectiveness of the training. PMID:25671082

    This study investigates the effect of early-life exposure to malaria on disease and work level in old age over the past one and a half centuries. Using longitudinal lifetime records of Union Army veterans, I first estimate that exposure to a malarial environment in early life (c.1840) substantially increased the likelihood of having various chronic diseases and not working in old age (c.1900). Second, from data on US cohorts born between 1891 and 1960, I find that those exposed to a higher level of the anti-malaria campaign, which began in 1921, had lower levels of work disability in old age. Third, I seek the same implications for the modern period by linking WHO's country statistics on DALYs among older populations in 2004 to country-level malaria risk in pre-eradication era. In the paper, I discuss possible mechanisms and propose the significance of malaria eradication and early-life conditions from a long-term perspective. PMID:23584052

  17. Financial Capability in Early Social Work Practice: Lessons for Today.

    2016-10-01

    During the profession's first decades, social workers tried to improve their clients’ financial capability (FC). This article describes the methods used by early social workers who attempted to enhance the FC of their clients, based on contemporary descriptions of their practice. Social workers initially emphasized thrift, later adding more sophisticated consideration of the cost of foods, rent, and other necessities. Social work efforts were furthered by home economists, who served as specialists in nutrition, clothing, interior design, and other topics related to homemaking. Early home economists included specialists in nutrition and family budgeting; these specialists worked with social services agencies to provide a financial basis for family budgets and assisted clients with family budgeting. Some agencies engaged home economists as consultants and as direct providers of instruction on home budgets for clients. By the 1930s, however, social work interest in family budget problems focused on the psychological meaning of low income to the client, rather than in measures to increase client FC. Consequently, social workers’ active engagement with family budget issues—engagement that characterized earlier decades—faded. These early efforts can inform contemporary practice as social workers are once again concerned about improving their clients’ FC.

    The first three years of life have been identified as key to promoting children's later wellbeing, and partnership working across the statutory and voluntary sectors has been proposed as one of the best ways to meet the needs of families. Child health clinics are attended by parents seeking reassurance or help and advice from a health professional regarding child health and development. They have been used in Oxford to develop Early Explorer clinics, in which the statutory health visiting service and voluntary sector Peers Early Education Programme work together with the aim of improving outcomes for children and families. These Early Explorer clinics provide the opportunity to engage parents in supporting their child's development through interaction and non-directed exploratory play. They also offer opportunities to identify vulnerable families, who are provided with additional support. This paper examines a model of partnership working between statutory and voluntary sectors aimed at maximising opportunities to promote the health and wellbeing of infants and their families.

    The public plays an important role in controlling the emergence and spread of antibiotic resistance. A large British survey showed that there is still public misunderstanding about microbes and antibiotics. e-Bug, a European DG Sanco sponsored project, aims to disseminate a school antibiotic and hygiene educational pack and website across Europe. Interactive science shows based on the e-Bug educational packs were developed to take the key health and hygiene messages from the e-Bug school resources to families. The science show was evaluated to assess public knowledge and understanding of antibiotics and antibiotic resistance pre and post intervention. An interactive stall comprised of a 3×2 m backing stand with background information, an interactive activity and discussions with a trained demonstrator was on display at a family holiday resort. Pre-piloted knowledge questionnaires were completed by parents and children pre and post intervention. Adult (≥19 years) baseline knowledge regarding antibiotics and antibiotic resistance was high although significant knowledge improvement was observed where baseline knowledge was low. Children's (5-11 years) knowledge around antibiotics and antibiotic resistance was significantly improved for all questions. The science show can be viewed as a success in improving parents' and children's knowledge of antibiotic use thereby highlighting the importance of educating the public through interaction.

    Early retirement is an increasing problem in the construction industry. There is limited information about causes leading employees to leave working life early. We have compared construction workers present situation with their perception of future demands at work to avoid early retirement. All 87 employees in a medium-sized Norwegian construction company participated in the study. All were men and answered questionnaires on health and pain, work ability, mechanical exposure, psychosocial conditions, and demands regarding future working conditions. Most workers showed good work ability, irrespective of age. Many reported high levels of mechanical exposure at work. The level of musculoskeletal pain was higher in the middle-aged (30-50 year old) age groups and seniors aged over 50 years than among the youngest workers less than 30 years of age. All workers reported that good health was important for continued working. Most workers stated that future work must not be too physically demanding. Many workers reported relatively low job satisfaction; consequently an interesting job was rated as important for continuing work. Good social conditions were a high priority. According to the examined construction workers, good health and reduced levels of mechanical exposure at work are essential to avoid early retirement.

    To characterize metabolic correlates of working memory impairment in clinically defined subtypes of early-onset Alzheimer's disease. Established models of working memory suggest a key role for frontal lobe function, yet the association in Alzheimer's disease between working memory impairment and visuospatial and language symptoms suggests that temporoparietal neocortical dysfunction may be responsible. Twenty-four patients with predominantly early-onset Alzheimer's disease were clinically classified into groups with predominantly amnestic, multidomain or visual deficits. Patients underwent neuropsychological evaluation focused on the domains of episodic and working memory, T1-weighted magnetic resonance imaging and brain fluorodeoxyglucose positron emission tomography. Fluorodeoxyglucose positron emission tomography data were analysed by using a region-of-interest approach. Patients with multidomain and visual presentations performed more poorly on tests of working memory compared with amnestic Alzheimer's disease. Working memory performance correlated with glucose metabolism in left-sided temporoparietal, but not frontal neocortex. Carriers of the apolipoprotein E4 gene showed poorer episodic memory and better working memory performance compared with noncarriers. Our findings support the hypothesis that working memory changes in early-onset Alzheimer's disease are related to temporoparietal rather than frontal hypometabolism and show dissociation from episodic memory performance. They further support the concept of subtypes of Alzheimer's disease with distinct cognitive profiles due to prominent neocortical dysfunction early in the disease course.

  4. An evaluation of nonclinical dissociation utilizing a virtual environment shows enhanced working memory and attention.

    Dissociation is a mental process resulting in the disruption of memory, perception, and sometimes identity. At a nonclinical level, only mild dissociative experiences occur. The nature of nonclinical dissociation is disputed in the literature, with some asserting that it is a beneficial information processing style and others positing that it is a psychopathological phenomenon. The purpose of this study was to further the understanding of nonclinical dissociation with respect to memory and attention, by including a more ecologically valid virtual reality (VR) memory task along with standard neuropsychological tasks. Forty-five undergraduate students from a small liberal arts college in the northeast participated for course credit. The participants completed a battery of tasks including two standard memory tasks, a standard attention task, and an experimental VR memory task; the VR task included immersion in a virtual apartment, followed by incidental object-location recall for objects in the virtual apartment. Support for the theoretical model portraying nonclinical dissociation as a beneficial information processing style was found in this study. Dissociation scores were positively correlated with working memory scores and attentional processing scores on the standard neuropsychological tasks. In terms of the VR task, dissociation scores were positively correlated with more false positive memories that could be the result of a tendency of nonclinical highly dissociative individuals to create more elaborative schemas. This study also demonstrates that VR paradigms add to the prediction of cognitive functioning in testing protocols using standard neuropsychological tests, while simultaneously increasing ecological validity.

    A variety of studies demonstrated that some forms of memory for music are spared in dementia, but only few studies have investigated patients with early stages of dementia. In this pilot-study we tested working memory for music in patients with mild cognitive impairment (MCI) and early stage Alzheimer's disease (AD) with a newly created test. The test probed working memory using 7 gradually elongated tone-lines and 6 chords which were each followed by 3 similar items and 1 identical item. The participants of the study, namely 10 patients with MCI, 10 patients with early stage AD and 23 healthy subjects were instructed to select the identical tone-line or chord. Subjects with MCI and early AD showed significantly reduced performance than controls in most of the presented tasks. In recognizing chords MCI- participants surprisingly showed an unimpaired performance. The gradual increase of the impairment during the preclinical phase of AD seems to spare this special ability in MCI.

    It is now established that attention influences working memory (WM) at multiple processing stages. This liaison between attention and WM poses several interesting empirical questions. Notably, does attention impact WM via its influences on early perceptual processing? If so, what are the critical factors at play in this attention-perception-WM interaction. I review recent data from our laboratory utilizing a variety of techniques (electroencephalography (EEG), functional MRI (fMRI) and transcranial magnetic stimulation (TMS)), stimuli (features and complex objects), novel experimental paradigms, and research populations (younger and older adults), which converge to support the conclusion that top-down modulation of visual cortical activity at early perceptual processing stages (100–200 ms after stimulus onset) impacts subsequent WM performance. Factors that affect attentional control at this stage include cognitive load, task practice, perceptual training, and aging. These developments highlight the complex and dynamic relationships among perception, attention, and memory. PMID:21184764

    Although work-related asthma and allergies are a huge burden for society, investigation of occupational exposures in early work life using an unexposed reference group is rare. Thus, the present analyses aimed to assess the potential impact of occupational exposure and other risk factors on the prevalence of work-related sensitisation and incidence of allergic rhinitis/asthma using a population-based approach and taking into account an unexposed reference group. In SOLAR (Study on Occupational Allergy Risks) II, German participants of ISAAC (International Study of Asthma and Allergies in Childhood) phase II were followed from childhood (9-11 years) until early adulthood (19-24 years). Data on 1570 participants were available to fit predictive models. Occupational exposure was not statistically significantly associated with disease prevalence/incidence. Sensitisation in childhood, parental asthma, environmental tobacco smoke exposure during puberty, sex and study location were statistically significant predictors of outcome. Our results indicate that occupational exposure is of little relevance for work-related sensitisation prevalence and allergic rhinitis/asthma incidence in early work life, while other risk factors can be used to improve career guidance for adolescents. Further research on the role of a potential healthy hire effect and the impact of longer exposure duration is needed. ©ERS 2014.

    Although deficits in working memory ability have been implicated in suboptimal decision making and risk taking among adolescents, its influence on early sexual initiation has so far not been examined. Analyzing 2 waves of panel data from a community sample of adolescents (N = 347; Mean age[baseline] = 13.4 years), assessed 1 year apart, the present study tested the hypothesis that weak working memory ability predicts early sexual initiation and explored whether this relationship is mediated by sensation seeking and 2 forms of impulsivity, namely acting-without-thinking and temporal discounting. The 2 forms of impulsivity were expected to be positively associated with early sexual initiation, whereas sensation seeking was hypothesized to be unrelated or to have a protective influence, due to its positive association with working memory. Results obtained from structural equation modeling procedures supported these predictions and in addition showed that the effects of 3 prominent risk factors (Black racial identity, low socioeconomic background, and early pubertal maturation) on early sexual initiation were entirely mediated by working memory and impulsivity. The findings are discussed in regard to their implications for preventing early sexual onset among adolescents. PMID:22369334

    Early numeracy is an important precursor for arithmetic performance, academic proficiency, and work success. Besides their apparent motor difficulties, children with cerebral palsy (CP) often show additional cognitive disturbances. In this study, we examine whether working memory, non-verbal intelligence, linguistic skills, counting and fine motor skills are positively related to the early numeracy performance of 6-year-old children with CP. A total of 56 children (M = 6.0, SD = 0.61, 37 boys) from Dutch special education schools participated in this cross-sectional study. Of the total group, 81% of the children have the spastic type of CP (33% unilateral and 66% bilateral), 9% have been diagnosed as having diskinetic CP, 8% have been diagnosed as having spastic and diskinetic CP and 2% have been diagnosed as having a combination of diskinetic and atactic CP. The children completed standardized tests assessing early numeracy performance, working memory, non-verbal intelligence, sentence understanding and fine motor skills. In addition, an experimental task was administered to examine their basic counting performance. Structural equation modeling showed that working memory and fine motor skills were significantly related to the early numeracy performance of the children (β = .79 and p < .001, β = .41 and p < .001, respectively). Furthermore, counting was a mediating variable between working memory and early numeracy (β = .57, p < .001). Together, these findings highlight the importance of working memory for early numeracy performance in children with CP and they warrant further research into the efficacy of intervention programs aimed at working memory training.

    We aimed to identify the best approach to work ability assessment in patients with thyroid disease by evaluating the factor structure, measurement equivalence, known-groups validity, and predictive validity of a broad set of work ability items. Based on the literature and interviews with thyroid patients, 24 work ability items were selected from previous questionnaires, revised, or developed anew. Items were tested among 632 patients with thyroid disease (non-toxic goiter, toxic nodular goiter, Graves' disease (with or without orbitopathy), autoimmune hypothyroidism, and other thyroid diseases), 391 of which had participated in a study 5 years previously. Responses to select items were compared to general population data. We used confirmatory factor analyses for categorical data, logistic regression analyses and tests of differential item function, and head-to-head comparisons of relative validity in distinguishing known groups. Although all work ability items loaded on a common factor, the optimal factor solution included five factors: role physical, role emotional, thyroid-specific limitations, work limitations (without disease attribution), and work performance. The scale on thyroid-specific limitations showed the most power in distinguishing clinical groups and time since diagnosis. A global single item proved useful for comparisons with the general population, and a thyroid-specific item predicted labor market exclusion within the next 5 years (OR 5.0, 95 % CI 2.7-9.1). Items on work limitations with attribution to thyroid disease were most effective in detecting impact on work ability and showed good predictive validity. Generic work ability items remain useful for general population comparisons.

    Gut microbiome dysbiosis is associated with numerous diseases, including type 1 diabetes. This pilot study determines how geographical location affects the microbiome of infants at high risk for type 1 diabetes in a population of homogenous HLA class II genotypes. High-throughput 16S rRNA sequencing was performed on stool samples collected from 90 high-risk, nonautoimmune infants participating in The Environmental Determinants of Diabetes in the Young (TEDDY) study in the U.S., Germany, Sweden, and Finland. Study site-specific patterns of gut colonization share characteristics across continents. Finland and Colorado have a significantly lower bacterial diversity, while Sweden and Washington state are dominated by Bifidobacterium in early life. Bacterial community diversity over time is significantly different by geographical location. The microbiome of high-risk infants is associated with geographical location. Future studies aiming to identify the microbiome disease phenotype need to carefully consider the geographical origin of subjects. © 2015 by the American Diabetes Association.

    Studies are increasingly focusing on the effects of prenatal alcohol exposure (PAE) on child health. The aim of this review was to provide paediatricians with new insights to help them communicate key messages about avoiding alcohol during pregnancy. Inspired by the 7th International Conference on Fetal Alcohol Spectrum Disorder, which focused on integrating research, policy and practice, we studied English language papers published since 2010 on how early PAE triggered epigenetic mechanisms that had an impact on the development of some chronic diseases. We also report the findings of a human study using three-dimensional photography of the face to explore associations between PAE and craniofacial phenotyping. Animal models with different alcohol exposure patterns show that early PAE may lead to long-term chronic effects, due to developmental programming for some adult diseases in cardiovascular, metabolic and renal systems. The study with three-dimensional photographing is very promising in helping paediatricians to understand how even small amounts of PAE can affect craniofacial phenotyping. Even low levels of PAE can cause adverse foetal effects and not just in the brain. It is not currently possible to determine a safe period and level when alcohol consumption would not affect the foetus. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Objectives The aim of the study was to assess the effectiveness of the use of part-time sick leave at the early (first 12 weeks) stage of work disability due to mental disorder or musculoskeletal disease on sustained return to work (RTW) and overall work participation. Methods In a nation-wide register-based quasi-experimental study, we compared sustained RTW (ie, ≥28 consecutive days at work) and 2-year work participation between the part- and full-time sickness absence (SA) benefit groups (N=1878 in each group) using propensity-score matching. Persons who received partial or full SA benefit due to musculoskeletal diseases or mental disorders between January 1, 2010 and December 31, 2011 were eligible as cases or controls, respectively. Results A higher proportion showed sustained RTW after part- compared to full-time sick leave [absolute risk difference 8.0%, 95% confidence interval (95% CI) 5.3-10.9]. Moreover, the proportion of time at work was at a 10.5% higher level in the part- compared to full-time sick leave group. The prevalence of full disability retirement was almost three-fold among the full- compared to part-time sick leave group, whereas partial disability retirement was 4.5-fold more prevalent in the part- compared to full-time sick leave group. Conclusions The use of part-time sick leave during the first three months of SA enhances RTW and overall work participation during two years among persons with mental disorders and musculoskeletal diseases. The prescription of part-time sick leave can be recommended at an early stage of work disability.

    Obesity contributes significantly to the development and evolution of cardiovascular disease (CVD) which is believed to be mediated by oxidative stress, inflammation and endothelial dysfunction. However, the vascular health of metabolically obese and normal weight (MONW) individuals is not completely comprehended. The purpose of our study was to evaluate vascular function on the basis of a high fat diet (HFD)-MONW rabbit model. Twenty four male rabbits were randomly assigned to receive either a regular diet (CD, n = 12) or a high-fat diet (18% extra fat on the regular diet, HFD, n = 12) for 6 weeks. Body weight, TBARS and gluthathione serum levels were similar between the groups; fasting glucose, triglycerides, C reactive protein (CRP), visceral adipose tissue (VAT), triglyceride-glucose index (TyG index) were higher in the HFD group. Compared to CD, the HFD rabbits had glucose intolerance and lower HDL-cholesterol and plasma nitrites levels. Thoracic aortic rings from HFD rabbits exhibited: (a) a reduced acetylcholine-induced vasorelaxation; (b) a greater contractile response to norepinephrine and KCl; (c) an improved angiotensin II-sensibility. The HFD-effect on acetylcholine-response was reversed by the cyclooxygenase-2 (COX-2) inhibitor (NS398) and the cyclooxygenase-1 inhibitor (SC560), and the HFD-effect on angiotensin II was reversed by NS398 and the TP receptor blocker (SQ29538). Immunohistochemistry and western blot studies showed COX-2 expression only in arteries from HFD rabbits. Our study shows a positive pro-inflammatory status of HFD-induced MONW characterized by raised COX-2 expression, increase of the CRP levels, reduction of NO release and oxidative stress-controlled conditions in an early stage of metabolic alterations characteristic of metabolic syndrome. Endothelial dysfunction and increased vascular reactivity in MONW individuals may be biomarkers of early vascular injury. Therefore, the metabolic changes induced by HFD even in normal

    Familial sick sinus syndrome (SSS) is often attributable to mutations in genes encoding the cardiac Na channel SCN5A and pacemaker channel HCN4. We previously found that SSS with SCN5A mutations shows early onset of manifestations and male predominance. Despite recent reports on the complications of atrial fibrillation (AF) and left ventricular noncompaction (LVNC) in patients with SSS caused by HCN4 mutations, their overall clinical spectrum remains unknown. The purpose of this study was to investigate the clinical and demographic features of SSS patients carrying HCN4 mutations. We genetically screened 38 unrelated SSS families and functionally analyzed the mutant SCN5A and HCN4 channels by patch clamping. We also evaluated the clinical features of familial SSS by a meta-analysis of 48 SSS probands with mutations in HCN4 (n = 16) and SCN5A (n = 32), including previously reported cases, and 538 sporadic SSS cases. We identified two HCN4 and three SCN5A loss-of-function mutations in our familial SSS cohort. Meta-analysis of HCN4 mutation carriers showed a significantly younger age at diagnosis (39.1 ± 21.7 years) than in sporadic SSS (74.3 ± 0.4 years; P <.001), but a significantly older age than in SCN5A mutation carriers (20.0 ± 17.6 years; P = .003). Moreover, HCN4 mutation carriers were more frequently associated with AF (43.8%) and LVNC (50%) and with older age at pacemaker implantation (43.5 ± 22.1 years) than were SCN5A mutation carriers (17.8 ± 16.5 years; P <.001). SSS with HCN4 mutations may form a distinct SSS subgroup characterized by early clinical manifestation after adolescence and frequent association with AF and LVNC.

    Purpose Men with a family history (FH) of prostate cancer (PCA) and African American (AA) men are at higher risk for PCA. Recruitment and retention of these high-risk men into early detection programs has been challenging. We report a comprehensive analysis on recruitment methods, show rates, and participant factors from the Prostate Cancer Risk Assessment Program (PRAP), which is a prospective, longitudinal PCA screening study. Materials and Methods Men 35–69 years are eligible if they have a FH of PCA, are AA, or have a BRCA1/2 mutation. Recruitment methods were analyzed with respect to participant demographics and show to the first PRAP appointment using standard statistical methods Results Out of 707 men recruited, 64.9% showed to the initial PRAP appointment. More individuals were recruited via radio than from referral or other methods (χ2 = 298.13, p < .0001). Men recruited via radio were more likely to be AA (p<0.001), less educated (p=0.003), not married or partnered (p=0.007), and have no FH of PCA (p<0.001). Men recruited via referrals had higher incomes (p=0.007). Men recruited via referral were more likely to attend their initial PRAP visit than those recruited by radio or other methods (χ2 = 27.08, p < .0001). Conclusions This comprehensive analysis finds that radio leads to higher recruitment of AA men with lower socioeconomic status. However, these are the high-risk men that have lower show rates for PCA screening. Targeted motivational measures need to be studied to improve show rates for PCA risk assessment for these high-risk men. PMID:19758657

    Determinants in the domains health, job characteristics, skills, and social and financial factors may influence early retirement through three central explanatory variables, namely, the ability, motivation, and opportunity to work. Based on the literature, we created the Early Retirement Model. This study aims to investigate whether data support the model and how it could be improved. Employees aged 58-62 years (N=1862), who participated in the first three waves of the Dutch Study on Transitions in Employment, Ability and Motivation (STREAM) were included. Determinants were assessed at baseline, central explanatory variables after one year, and early retirement after two years. Structural equation modeling was applied. Testing the Early Retirement Model resulted in a model with good fit. Health, job characteristics, skills, and social and financial factors were related to the ability, motivation and/or opportunity to work (significant β range: 0.05-0.31). Lower work ability (β=-0.13) and less opportunity to work (attitude colleagues and supervisor about working until age 65: β=-0.24) predicted early retirement, whereas the motivation to work (work engagement) did not. The model could be improved by adding direct effects of three determinants on early retirement, ie, support of colleagues and supervisor (β=0.14), positive attitude of the partner with respect to early retirement (β=0.15), and not having a partner (β=-0.13). The Early Retirement Model was largely supported by the data but could be improved. The prolongation of working life might be promoted by work-related interventions focusing on health, work ability, the social work climate, social norms on prolonged careers, and the learning environment.

    In amyotrophic lateral sclerosis caused by mutations in Cu/Zn-superoxide dismutase (SOD1), altered solubility and aggregation of the mutant protein implicates failure of pathways for detecting and catabolizing misfolded proteins. Our previous studies demonstrated early reduction of proteasome-mediated proteolytic activity in lumbar spinal cord of SOD1(G93A) transgenic mice, tissue particularly vulnerable to disease. The purpose of this study was to identify any underlying abnormalities in proteasomal structure. In lumbar spinal cord of pre-symptomatic mice [postnatal day 45 (P45) and P75], normal levels of structural 20S alpha subunits were incorporated into 20S/26S proteasomes; however, proteasomal complexes separated by native gel electrophoresis showed decreased immunoreactivity with antibodies to beta3, a structural subunit of the 20S proteasome core, and beta5, the subunit with chymotrypsin-like activity. This occurred prior to increase in beta5i immunoproteasomal subunit. mRNA levels were maintained and no association of mutant SOD1 with proteasomes was identified, implicating post-transcriptional mechanisms. mRNAs also were maintained in laser captured motor neurons at a later stage of disease (P100) in which multiple 20S proteins are reduced relative to the surrounding neuropil. Increase in detergent-insoluble, ubiquitinated proteins at P75 provided further evidence of stress on mechanisms of protein quality control in multiple cell types prior to significant motor neuron death.

    Existing studies showing an association between substance use disorders and Internet addiction have been limited due their cross-sectional design. This longitudinal study investigated the association between addictive Internet use during adolescence and heavy drinking and cigarette smoking in early adulthood. We focused on middle school students from the Korea Youth Panel Study who were 15 in 2003:1804 who did not drink alcohol and 2277 who did not smoke. Multivariate logistic analysis investigated the relationships between Internet use at the age of 15, with regard to location, time spent and reason for use, and drinking and smoking at the age of 20. Using the Internet for chatting, games and adult websites at the age of 15 had a significant association with heavy drinking at the age of 20. The Internet café as the location for Internet use at the age of 15 was associated with smoking behaviour at the age of 20. This study confirmed significant associations between addictive use of the Internet at the age of 15 and heavy drinking and cigarette smoking at the age of 20. The findings demonstrated the negative effects of addictive Internet use, one of the biggest problems with adolescents. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    The aim was to study the time-of-day variations of cortisol, fatigue and sleep disturbances in sound engineers in relation to job task and shift work. The concentration of saliva cortisol and feeling of stress, sleepiness and fatigue were followed at three hour intervals in 21 sound engineers: 13 sound engineers, aged 45.1 +/- 7.3 years, broadcasting in a life show during fast forward rotating shifts and 8 sound engineers, aged 47.1 +/- 9.8 years, making records in a studio during fast rotating day shifts. Cortisol concentration was assessed in saliva with radioimmunological kits. The participants reported for stress symptoms during the shifts and filled sleep diary. The data were analyzed by tests of between-subjects effects (SPSS). A trend for higher cortisol was found with the group broadcasting in a life show. The sound engineers broadcasting in a life show reported higher scores of stress, sleepiness and fatigue, but no significant differences concerning the sleep disturbances between the groups were found. In conclusion our data show moderate level of stress and fatigue with the studied sound engineers, higher with the subjects broadcasting in a life show. The quality of sleep showed no significant differences between the studied groups, an indication that the sound engineers were able to tolerate the fast forward rotating shifts.

    Non-eosinophilic nasal polyps (NPs) show less inflammatory changes and are less commonly associated with lower airway inflammatory disorders such as asthma, compared with eosinophilic NPs. However, the development of non-eosinophilic NPs which is a predominant subtype in Asian population still remains unclear. A total of 81 patients (45 with non-eosinophilic NPs and 36 with eosinophilic NPs) were enrolled. Clinical information and computed tomography (CT), endoscopic, and histological findings were investigated. Tissue samples were analyzed for total IgE levels and for mRNA expression levels of interleukin (IL)-4, IL-5, IL-13, interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL-17A, IL-22, IL-23p19, transforming growth factor (TGF)-β1, TGF-β2, TGF-β3, and periostin. Immunostaining assessment of Ki-67 as a proliferation marker was performed. We found that epithelial in-growing patterns such as pseudocysts were more frequently observed in histological and endoscopic evaluations of non-eosinophilic NPs, which was linked to increase epithelial staining of Ki-67, a proliferating marker. Eosinophilic NPs were characterized by high infiltration of inflammatory cells, compared with non-eosinophilic NPs. To investigate the developmental course of each subtype, CT was analyzed according to CT scores and subtypes. Non-eosinophilic NPs showed more localized pattern and maxillary sinus involvement, but lesser olfactory involvement in early stage whereas eosinophilic NPs were characterized by diffuse ethmoidal and olfactory involvement. In addition, high ethmoidal/maxillary (E/M) CT scores, indicating ethmoidal dominant involvement, were one of surrogate markers for eosinophilic NP. E/M CT scores was positively correlated with levels of TH2 inflammatory markers, including IL-4, IL-5, periostin mRNA expression and total IgE levels in NPs, whereas levels of the TH1 cytokine, IFN- γ were inversely correlated. Moreover, if the combinatorial algorithm meet the three of the

  11. Do early neural correlates of visual consciousness show the oblique effect? A binocular rivalry and event-related potential study.

    When dissimilar images are presented one to each eye, we do not see both images; rather, we see one at a time, alternating unpredictably. This is called binocular rivalry, and it has recently been used to study brain processes that correlate with visual consciousness, because perception changes without any change in the sensory input. Such studies have used various types of images, but the most popular have been gratings: sets of bright and dark lines of orthogonal orientations presented one to each eye. We studied whether using cardinal rival gratings (vertical, 0°, and horizontal, 90°) versus oblique rival gratings (left-oblique, -45°, and right-oblique, 45°) influences early neural correlates of visual consciousness, because of the oblique effect: the tendency for visual performance to be greater for cardinal gratings than for oblique gratings. Participants viewed rival gratings and pressed keys indicating which of the two gratings they perceived, was dominant. Next, we changed one of the gratings to match the grating shown to the other eye, yielding binocular fusion. Participants perceived the rivalry-to-fusion change to the dominant grating and not to the other, suppressed grating. Using event-related potentials (ERPs), we found neural correlates of visual consciousness at the P1 for both sets of gratings, as well as at the P1-N1 for oblique gratings, and we found a neural correlate of the oblique effect at the N1, but only for perceived changes. These results show that the P1 is the earliest neural activity associated with visual consciousness and that visual consciousness might be necessary to elicit the oblique effect.

    In a previous study, we found a decline in the proportion of Memorial University of Newfoundland (MUN) medical alumni practising in rural areas, particularly in Newfoundland and Labrador. The current study focused on the work location of recent graduates and examined the predictors of working in rural Canada and in rural Newfoundland and Labrador within the first 15 years following graduation. We linked data from graduating class lists and the alumni and postgraduate databases with Scott's Medical Database to create a record of all graduates from 1973 to 2008, including their work location. We identified differences and significant predictors for each outcome and then described and compared the characteristics of 4 cohorts of graduating classes. In their early career, 127/1113 (11.4%) MUN medical graduates were working in rural Canada, and 57 (5.1%) were working in rural Newfoundland and Labrador. Having a rural background and being a family physician were predictors of working in rural Canada, and having a rural background, doing at least part of the residency at MUN, being from Newfoundland and Labrador and being a family physician were predictors of working in rural Newfoundland and Labrador. Seventy-four (13.6%) and 33 (6.1%) of 1989-1998 graduates worked in rural Canada and rural Newfoundland and Labrador, respectively, compared to 53 (9.3%) and 24 (4.2%), respectively, of 1999-2008 graduates. The proportion of MUN medical graduates who worked in rural communities early in their career decreased among recent cohorts. The results show the impact of changes in the characteristics of MUN medical graduates, who increasingly opt for specialist practice and residency training outside the province, and the important role of local postgraduate training.

    Little is known about the balance between work demands and treatment plans for >4.3 million working-age cancer survivors in the USA. To describe changes in work status for gynaecological cancer survivors during the first 6 months following diagnosis and their experience with their employers' programmes and policies. One hundred and ten gynaecological cancer survivors who were working at the time of their cancer diagnosis completed a survey. Case record reviews documented their clinical characteristics and treatment details. Ninety-five women (86%) had surgery; 81 (74%) received chemotherapy, radiotherapy or both in addition to surgery. Nine per cent of women said that they changed their treatment plan because of their jobs; in contrast, 62% of women said that they changed their work situation to accommodate their treatment plan. Overall, the most common month for women to stop working was Month 1 (41%), to decrease hours was Month 2 (32%) and to increase hours was Month 6 (8%). Twenty-eight per cent of women were aware of employer policies that assisted the return to work process; 70% of women were familiar with the Family and Medical Leave Act (FMLA) and 56% with the Americans with Disabilities Act (ADA). Only 26% completed a formal request for work accommodations. After 6 months, 56 of 83 women (67%) remained working or had returned to work. Work patterns varied for these gynaecological cancer survivors over the first 6 months following diagnosis. Opportunities exist to improve communication about work and treatment expectations between cancer survivors, occupational health professionals, employers and treating clinicians.

    2017-01-01

    Macrophage migration inhibitory factor (MIF) is a pleiotropic, constitutively expressed, pro-inflammatory cytokine and an important regulator of immune responses. d-dopachrome tautomerase (DDT), a newly described member of the MIF protein superfamily, shares sequence homology and biological activities with MIF. We recently reported that high expression levels of MIF sustain innate immune responses in newborns. Here, we elected to further characterize age-dependent MIF expression and to define whether DDT shares a similar expression profile with MIF. Therefore, we delineated the circulating concentrations of MIF and DDT throughout life using a large cohort of 307 subjects including fetuses, newborns, infants, children, and adults. Compared to levels measured in healthy adults (median: 5.7 ng/ml for MIF and 16.8 ng/ml for DDT), MIF and DDT plasma concentrations were higher in fetuses (median: 48.9 and 29.6 ng/ml), increased further at birth (median: 82.6 and 52.0 ng/ml), reached strikingly elevated levels on postnatal day 4 (median: 109.5 and 121.6 ng/ml), and decreased to adult levels during the first months of life. A strong correlation was observed between MIF and DDT concentrations in all age groups (R = 0.91, P < 0.0001). MIF and DDT levels correlated with concentrations of vascular endothelial growth factor, a protein upregulated under low oxygen tension and implicated in vascular and lung development (R = 0.70, P < 0.0001 for MIF and R = 0.65, P < 0.0001 for DDT). In very preterm infants, lower levels of MIF and DDT on postnatal day 6 were associated with an increased risk of developing bronchopulmonary dysplasia and late-onset neonatal sepsis. Thus, MIF and DDT plasma levels show a highly specific developmental profile in early life, supporting an important role for these cytokines during the neonatal period. PMID:28179905

    Objectives People of low socioeconomic status are shorter than those of high socioeconomic status. The first two years of life being critical for height development, we hypothesized that a low socioeconomic status is associated with a slower linear growth in early childhood. We studied maternal educational level (high, mid-high, mid-low, and low) as a measure of socioeconomic status and its association with repeatedly measured height in children aged 0–2 years, and also examined to what extent known determinants of postnatal growth contribute to this association. Methods This study was based on data from 2972 mothers with a Dutch ethnicity, and their children participating in The Generation R Study, a population-based cohort study in Rotterdam, the Netherlands (participation rate 61%). All children were born between April 2002 and January 2006. Height was measured at 2 months (mid-90% range 1.0–3.9), 6 months (mid-90% range 5.6–11.4), 14 months (mid-90% range 13.7–17.9) and 25 months of age (mid-90% range 23.6–29.6). Results At 2 months, children in the lowest educational subgroup were shorter than those in the highest (difference: −0.87 cm; 95% CI: −1.16, −0.58). Between 1 and 18 months, they grew faster than their counterparts. By 14 months, children in the lowest educational subgroup were taller than those in the highest (difference at 14 months: 0.40 cm; 95% CI: 0.08,0.72). Adjustment for other determinants of postnatal growth did not explain the taller height. On the contrary, the differences became even larger (difference at 14 months: 0.61 cm; 95% CI: 0.26,0.95; and at 25 months: 1.00 cm; 95% CI: 0.57,1.43) Conclusions Compared with children of high socioeconomic status, those of low socioeconomic status show an accelerated linear growth until the18th month of life, leading to an overcompensation of their initial height deficit. The long-term consequences of these findings remain unclear and require further study. PMID:22649522

    It is well understood nowadays that changes in the mammographic parenchymal pattern are an indicator of a risk of breast cancer and we have developed a statistical method that estimates the mammogram regions where the parenchymal changes, due to breast cancer, occur. This region of interest is computed from a score map by utilising the anatomical breast coordinate system developed in our previous work. The method also makes an automatic scale selection to avoid overfitting while the region estimates are computed by a nested cross-validation scheme. In this way, it is possible to recover those mammogram regions that show a significant difference in classification scores between the cancer and the control group. Our experiments suggested that the most significant mammogram region is the region behind the nipple and that can be justified by previous findings from other research groups. This result was conducted on the basis of the cross-validation experiments on independent training, validation and testing sets from the case-control study of 490 women, of which 245 women were diagnosed with breast cancer within a period of 2-4 years after the baseline mammograms. We additionally generalised the estimated region to another, mini-MIAS study and showed that the transferred region estimate gives at least a similar classification result when compared to the case where the whole breast region is used. In all, by following our method, one most likely improves both preclinical and follow-up breast cancer screening, but a larger study population will be required to test this hypothesis.

    The purpose of this study was to determine whether grain handlers underwent work-related changes in their pulmonary function and, if so, to examine the dose-effect relationships with dust exposure. The pulmonary function of grain handlers was measured at the beginning and end of work shifts over a period of one week, during which their exposure to dust was measured daily. The results showed changes indicative of a within-day obstructive change, in addition to a small restrictive defect occurring over the course of a week. Civic outside labourers who were examined as a control group showed a similar within-week obstructive change without any associated restriction of lung volume. The data on the grain handlers were also used to examine the dose-effect relationships of dust exposure, both on baseline pulmonary function and on within-day changes in these measurements. The baseline flow rates of workers who did not wear a mask were found to vary inversely with their average exposure to respirable dust. In addition, the flow rates underwent a within-day decrease that varied directly with their corresponding exposure to respirable dust and was unrelated to mask wearing. The median of the slopes for this relationship indicated that 50% of the subjects had a decrease of at least 923 ml/s in the value of their Vmax50%VC for each 1 mg/m3 increase in the concentration of respirable dust. Non-respirable dust did not have a measurable effect either on the baseline or the within-day changes in pulmonary function. The acute changes were unaffected by age, duration of employment, or extent of smoking. PMID:7138793

    A significant component of the work of public health nurses and paraprofessional home visitors who provide home visits to families with young children involves establishing relationships to effectively deliver the visiting program. The purpose of this qualitative and descriptive study was to describe the relationships among participants in a home visiting program in one regional health authority in the Canadian province of Manitoba. Interviews were carried out with 24 public health nurses, 14 home visitors, and 20 parents. The findings related to establishing, maintaining, and terminating relationships as well as factors influencing relationship work are described. Public health nurses and home visitors put significant effort into the work of establishing relationships with each other and their clients and require adequate training, sufficient human resources, and support from the program's administration to sustain these relationships.

    Cannabis is the most commonly used illicit drug. Prevalence rates are particularly high among adolescents. Neuropsychological studies have identified cannabis-associated memory deficits, particularly linked to an early onset of use. However, it remains unclear, whether the age of onset accounts for altered cortical activation patterns usually observed in cannabis users. Functional magnetic resonance imaging was used to examine cortical activation during verbal working memory challenge in (1) early-onset (onset before the age of sixteen; n=26) and (2) late-onset cannabis users (age at onset at least sixteen; n=17). Early-onset users showed increased activation in the left superior parietal lobe. Correlational analyses confirmed the association between an earlier start of use and increased activity. Contrariwise neither cumulative dose, frequency nor time since last use was significantly associated with cortical activity. Our findings suggest that an early start of cannabis use is associated with increased cortical activation in adult cannabis users, possibly reflecting suboptimal cortical efficiency during cognitive challenge. The maturing brain might be more vulnerable to the harmful effects of cannabis use. However, due to a lack of a non-using control group we cannot exclude alternative interpretations.

  8. Assessing the Effect of Early Visual Cortex Transcranial Magnetic Stimulation on Working Memory Consolidation.

    Maintaining visual working memory (VWM) representations recruits a network of brain regions, including the frontal, posterior parietal, and occipital cortices; however, it is unclear to what extent the occipital cortex is engaged in VWM after sensory encoding is completed. Noninvasive brain stimulation data show that stimulation of this region can affect working memory (WM) during the early consolidation time period, but it remains unclear whether it does so by influencing the number of items that are stored or their precision. In this study, we investigated whether single-pulse transcranial magnetic stimulation (spTMS) to the occipital cortex during VWM consolidation affects the quantity or quality of VWM representations. In three experiments, we disrupted VWM consolidation with either a visual mask or spTMS to retinotopic early visual cortex. We found robust masking effects on the quantity of VWM representations up to 200 msec poststimulus offset and smaller, more variable effects on WM quality. Similarly, spTMS decreased the quantity of VWM representations, but only when it was applied immediately following stimulus offset. Like visual masks, spTMS also produced small and variable effects on WM precision. The disruptive effects of both masks and TMS were greatly reduced or entirely absent within 200 msec of stimulus offset. However, there was a reduction in swap rate across all time intervals, which may indicate a sustained role of the early visual cortex in maintaining spatial information.

    Reforming China's public hospitals to curb widespread overtreatment and improve the quality and affordability of care has been the most challenging aspect of that nation's ambitious health reform, which began in 2009. This article describes a pilot project under way in several of China's provinces that combines payment reform with the implementation of evidence-based clinical pathways at a few hospitals serving rural areas. Results to date include reduced length-of-stay and prescription drug use and higher patient and provider satisfaction. These early results suggest that the pilot may be achieving its goals, which may have far-reaching and positive implications for China's ongoing reform.

    Between 20 and 40 % of female sex workers (FSWs) began sex work before age 18. Little is known concerning whether early initiation of sex work impacts later experiences in adulthood, including violence victimization. This paper examines the relationship between early initiation of sex work and violence victimization during adulthood. The sample included 816 FSWs in Mombasa, Kenya, recruited from HIV prevention drop-in centers who were 18 years or older and moderate-risk drinkers. Early initiation was defined as beginning sex work at 17 or younger. Logistic regression modeled recent violence as a function of early initiation, adjusting for drop-in center, age, education, HIV status, supporting others, and childhood abuse. Twenty percent of the sample reported early initiation of sex work. Although both early initiators and other FSWs reported commonly experiencing recent violence, early initiators were significantly more likely to experience recent physical and sexual violence and verbal abuse from paying partners. Early initiation was not associated with physical or sexual violence from non-paying partners. Many FSWs begin sex work before age 18. Effective interventions focused on preventing this are needed. In addition, interventions are needed to prevent violence against all FSWs, in particular, those who initiated sex work during childhood or adolescence.

    2016-01-01

    We examined whether a reduced ability to ignore irrelevant information is responsible for the age-related decline of working-memory (WM) functions. By means of event-related brain potentials we will show that filtering is not out of service in older adults but shifted to a later processing stage. Participants performed a visual short-term memory task (change-detection task) in which targets were presented along with distractors. To allow early selection, a cue was presented in advance of each display, indicating where the targets were to appear. Despite this relatively easy selection criterion, older adults’ filtering was delayed as indicated by the amplitude pattern of the contralateral delay activity. Importantly, WM-equated younger adults did not show a delay indicating that the delay is specific to older adults and not a general phenomenon that comes with low WM capacity. Moreover, the analysis of early visual potentials revealed qualitatively different perceptual/attentional processing between the age groups. Young adults exhibited stronger distractor sensitivity that in turn facilitated filtering. Older adults, in contrast, seemed to initially store distractors and to suppress them after the fact. These early-selection versus late-correction modes suggest an age-related shift in the strategy to control the contents of WM. PMID:27253867

    Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face-to-face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family-centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities. © 2013 International Union of Psychological Science.

  18. Visual working memory gives up attentional control early in learning: ruling out interhemispheric cancellation.

    PubMed

    Reinhart, Robert M G; Carlisle, Nancy B; Woodman, Geoffrey F

    2014-08-01

    Current research suggests that we can watch visual working memory surrender the control of attention early in the process of learning to search for a specific object. This inference is based on the observation that the contralateral delay activity (CDA) rapidly decreases in amplitude across trials when subjects search for the same target object. Here, we tested the alternative explanation that the role of visual working memory does not actually decline across learning, but instead lateralized representations accumulate in both hemispheres across trials and wash out the lateralized CDA. We show that the decline in CDA amplitude occurred even when the target objects were consistently lateralized to a single visual hemifield. Our findings demonstrate that reductions in the amplitude of the CDA during learning are not simply due to the dilution of the CDA from interhemispheric cancellation.

    Many Western welfare states have introduced early-return-to-work policies, in which getting sick-listed people back to work before they have fully recovered is presented as a rather unproblematic approach. This reflects a belief in the ability of employers and the labour market to solve sickness absence. Against this background, the aim of this study was to analyse return-to-work practice in local workplace contexts, in relation to Swedish early-return-to-work policy. Semi-structured interviews were conducted with 18 matched pairs of workers and managers. The material, comprising a total of 36 interviews, was analysed using qualitative content analysis. Three main themes were identified: (1) intensive workplaces and work conditions (2) employer support-a function of worker value and (3) work attachment and resistance to job transition. The results reflected the intensity of modern working life, which challenged return-to-work processes. Managers had different approaches to workers' return-to-work, depending on how they valued the worker. While managers used the discourse of 'new opportunities' and 'healthy change' to describe the transition process (e.g. relocation, unemployment and retirement), workers regularly experienced transitions as difficult and unjust. In the context of early-return-to-work policy and the intensity of modern working life, a great deal of responsibility was placed on workers to be adaptable to workplace demands in order to be able to return and stay at work. Overall, this study illustrates an emerging social climate where sick-listed workers are positioned as active agents who must take responsibility for sick leave and return-to-work process.

    To observe the accommodative accuracy of children with early-onset myopia at different near-work distances, and discuss the relationship between accommodative accuracy and early-onset myopia. This was a case-control study. Thirty-seven emmetropic children, 41 early-onset myopic children without correction, and 39 early-onset myopic children with spectacles, aged 7 to 13 years, were included. Measures of refractive errors and accommodative accuracy at four near-work distances, including 50 cm, 40 cm, 30 cm, and 20 cm, were made using the binocular fusion cross cylinder (FCC) of an automatic phoropter. Most candidates showed accommodative lags, including the children with emmetropia. The ratio of lags in all candidates at different near-work distances was 75.21% (50 cm), 87.18% (40 cm), 92.31% (30 cm), and 98.29% (20 cm), respectively. All accommodative accuracies became worse, and the accommodative lag ratio and values of FCC increased, along with the shortening of the distance. The difference in accommodative accuracy among groups was statistically significant at 30 cm (χ(2)=7.852, P= 0.020) and 20 cm (χ(2)=6.480, P=0.039). The values of FCC among groups were significantly different at 30 cm (F=3.626, P=0.030) and 20 cm (F=3.703, P=0.028), but not at 50 cm and 40 cm (P>0.05). In addition, the FCC values of 30 cm and 20 cm had a statistically significant difference between myopic children without correction [(1.25±0.44) D and (1.76±0.43) D] and emmetropic children [(0.95±0.52) D and (1.41±0.58) D] (P=0.012, 0.008). The correlation between diopters of myopia and accommodative accuracy at different nearwork distances was not statistically significant (P>0.05). However, the correlation between diopters of myopia and the accommodative lag value (FCC) at 20 cm was statistically significant (r=0.246, P=0.028). The closer the near-work distance is, the worse the accommodative accuracy is. This is more significant in early-onset myopia, especially myopia without

    2012-12-01

    I became involved with the atmospheric chemistry of chlorofluorocarbons (CFCs) shortly after joining Sherry Rowland's research group at the University of California, Irvine, in 1973. CFCs had been detected in the troposphere by James Lovelock in 1971, and the question we set out to answer was the fate of these compounds of industrial origin in the environment, as well as possibly identifying any consequences of their accumulation in the atmosphere. After examining many potential sinks for these compounds we realized that because of their unusual stability the most likely destruction process was photolysis in the stratosphere. I carried out measurements of the absorption spectra of these compounds in the near ultraviolet; previous work involved only spectra in the far ultraviolet, not relevant for atmospheric chemistry. The results indicated that photolysis would take place in the upper stratosphere. I subsequently carried out calculations using one-dimensional atmospheric models to estimate their atmospheric residence times, which turned out to be many decades. We realized that the chlorine atoms generated by photolysis of the CFCs would participate in a catalytic chain reaction that would efficiently destroy ozone. Furthermore, we estimated that the amount of CFCs produced industrially was comparable to the amount of nitric oxide produced naturally in the stratosphere by the decomposition of nitrous oxide; work by Paul Crutzen and Harold Johnston had indicated that the abundance of ozone in the stratosphere was controlled by nitric oxide. We then formulated the hypothesis that the continued release of CFCs to the environment posed a threat to the stability of the ozone layer, and published our results in the journal Nature in 1974. The publication was noticed almost exclusively by the community of experts in stratospheric chemistry, and hence Sherry Rowland and I decided at that time that it was our responsibility to communicate this finding to society at large

    People with neuropsychiatric disorders such as schizophrenia often display deficits in spatial working memory and attention. Evaluating working memory and attention in schizophrenia patients is usually based on traditional tasks and the interviewer's judgment. We developed a simple Spatial Working Memory and Attention Test on Paired Symbols (SWAPS). It takes only several minutes to complete, comprising 101 trials for each subject. In this study, we tested 72 schizophrenia patients and 188 healthy volunteers in China. In a healthy control group with ages ranging from 12 to 60, the efficiency score (accuracy divided by reaction time) reached a peak in the 20-27 age range and then declined with increasing age. Importantly, schizophrenia patients failed to display this developmental trend in the same age range and adults had significant deficits compared to the control group. Our data suggests that this simple Spatial Working Memory and Attention Test on Paired Symbols can be a useful tool for studies of spatial working memory and attention in neuropsychiatric disorders.

    Behavioural and neurophysiological evidence suggest that vision plays an important role in the emergence and development of arithmetic abilities. However, how visual deprivation impacts on the development of arithmetic processing remains poorly understood. We compared the performances of early (EB), late blind (LB) and sighted control (SC) individuals during various arithmetic tasks involving addition, subtraction and multiplication of various complexities. We also assessed working memory (WM) performances to determine if they relate to a blind person's arithmetic capacities. Results showed that EB participants performed better than LB and SC in arithmetic tasks, especially in conditions in which verbal routines and WM abilities are needed. Moreover, EB participants also showed higher WM abilities. Together, our findings demonstrate that the absence of developmental vision does not prevent the development of refined arithmetic skills and can even trigger the refinement of these abilities in specific tasks.

    Improved feed efficiency is a primary goal in dairy production to reduce feed costs and negative impacts of production on the environment. Estimates for efficiency of feed conversion to milk production based on residual feed intake (RFI) in dairy cattle are limited, primarily due to a lack of individual feed intake measurements for lactating cows. Feed intake was measured in Holstein cows during the first 90 d of lactation to estimate the heritability and repeatability of RFI, minimum test duration for evaluating RFI in early lactation, and its association with other production traits. Data were obtained from 453 lactations (214 heifers and 239 multiparous cows) from 292 individual cows from September 2007 to December 2011. Cows were housed in a free-stall barn and monitored for individual daily feed consumption using the GrowSafe 4000 System (GrowSafe Systems, Ltd., Airdrie, AB, Canada). Animals were fed a total mixed ration 3 times daily, milked twice daily, and weighed every 10 to 14 d. Milk yield was measured at each milking. Feed DM percentage was measured daily, and nutrient composition was analyzed from a weekly composite. Milk composition was analyzed weekly, alternating between morning and evening milking periods. Estimates of RFI were determined as the difference between actual energy intake and predicted intake based on a linear model with fixed effects of parity (1, 2, ≥ 3) and regressions on metabolic BW, ADG, and energy-corrected milk yield. Heritability was estimated to be moderate (0.36 ± 0.06), and repeatability was estimated at 0.56 across lactations. A test period through 53 d in milk (DIM) explained 81% of the variation provided by a test through 90 DIM. Multiple regression analysis indicated that high efficiency was associated with less time feeding per day and slower feeding rate, which may contribute to differences in RFI among cows. The heritability and repeatability of RFI suggest an opportunity to improve feed efficiency through genetic

    Aim Early working memory is emerging as an important indicator of developmental outcome predicting later cognitive, behavioural and academic competencies. The current study compared early working memory in a sample of toddlers (18–22 months) born very low birth weight (VLBW; n = 40) and full term (n = 51) and the relationship between early working memory, mental developmental index (MDI), and maternal communication in both samples. Methods Early working memory, measured by object permanence; Bayley mental developmental index; and maternal communication, coded during mother-toddler play interaction, were examined in 39 toddlers born VLBW and 41 toddlers born full term. Results Toddlers born VLBW were found to be 6.4 times less likely to demonstrate attainment of object permanence than were toddlers born full term, adjusting for age at testing. MDI and maternal communication were found to be positively associated with attainment of object permanence in the VLBW group only. Conclusion The difference found in the early working memory performance of toddlers born VLBW, compared with those born full term, emphasizes the importance of assessing early working memory in at-risk populations, while the maternal communication finding highlights potential targets of intervention for improving working memory in toddlers born VLBW.

    2013-01-01

    Visual working memory (VWM) is a core cognitive system with a highly limited capacity. The present study is the first to examine VWM capacity limits in early development using functional neuroimaging. We recorded optical neuroimaging data while 3- and 4-year-olds completed a change detection task where they detected changes in the shapes of objects after a brief delay. Near-infrared sources and detectors were placed over the following 10–20 positions: F3 and F5 in left frontal cortex, F4 and F6 in right frontal cortex, P3 and P5 in left parietal cortex, and P4 and P6 in right parietal cortex. The first question was whether we would see robust task-specific activation of the frontal-parietal network identified in the adult fMRI literature. This was indeed the case: three left frontal channels and 11 of 12 parietal channels showed a statistically robust difference between the concentration of oxygenated and deoxygenated hemoglobin following the presentation of the sample array. Moreover, four channels in the left hemisphere near P3, P5, and F5 showed a robust increase as the working memory load increased from 1–3 items. Notably, the hemodynamic response did not asymptote at 1–2 items as expected from previous fMRI studies with adults. Finally, 4-year-olds showed a more robust parietal response relative to 3-year-olds, and an increasing sensitivity to the memory load manipulation. These results demonstrate that fNIRS is an effective tool to study the neural processes that underlie the early development of VWM capacity. PMID:23707803

    This study presents an integrative model of early retirement using data from the Wisconsin Longitudinal Study. The model extends prior work by incorporating work-family conflict to capture the interaction between the work and family domains and by assuming proximal and distal predictors of early retirement. More precisely, the model suggests that family and job demands and resources predict family-to-work and work-to-family conflict, respectively. All of these factors are presumed to have only indirect effects on retirement timing via the intervening effect of quality of life measures, that is, marital satisfaction, job satisfaction and health. The authors assume that these three factors constitute predictors of early retirement in addition to socioeconomic status and the availability of a pension plan and health insurance. The model was tested with structural equation modeling techniques, and the results were supportive. Therefore, the proposed model offers a general framework for the integration of previous research findings. PMID:21430790

  17. Positive work environments of early-career registered nurses and the correlation with physician verbal abuse.

    2013-01-01

    Verbal abuse in the workplace is experienced by registered nurses (RNs) worldwide; physicians are one of the main sources of verbal abuse. To examine the relationship between levels of physician verbal abuse of early-career RNs and demographics, work attributes, and perceived work environment. Fourth wave of a mailed national panel survey of early career RNs begun in 2006. RNs' perception of verbal abuse by physicians was significantly associated with poor workgroup cohesion, lower supervisory and mentor support, greater quantitative workload, organizational constraints, and nurse-colleague verbal abuse, as well as RNs' lower job satisfaction, organizational commitment, and intent to stay. RNs working in unfavorable work environments experience more physician abuse and have less favorable work attitudes. Causality is unclear: do poor working conditions create an environment in which physicians are more likely to be abusive, or does verbal abuse by physicians create an unfavorable work environment?

  18. Individuals with Low Working Memory Spans Show Greater Interference from Irrelevant Information Because of Poor Source Monitoring, Not Greater Activation

    2014-01-01

    Although individuals with high and low working memory (WM) span appear to differ in the extent to which irrelevant information interferes with their performance on WM tasks, the locus of this interference is not clear. The present study investigated whether, when performing a WM task, high- and low-span individuals differ in the activation of formerly relevant, but now irrelevant items, and/or in their ability to correctly identify such irrelevant items. This was done in two experiments, both of which used modified complex WM span tasks. In Experiment 1, the span task included an embedded lexical decision task designed to obtain an implicit measure of the activation of both currently and formerly relevant items. In Experiment 2, the span task included an embedded recognition judgment task designed to obtain an explicit measure of both item and source recognition ability. The results of these experiments indicate that low-span individuals do not hold irrelevant information in a more active state in memory than high-span individuals, but rather that low-span individuals are significantly poorer at identifying such information as irrelevant at the time of retrieval. These results suggest that differences in the ability to monitor the source of information, rather than differences in the activation of irrelevant information, are the more important determinant of performance on WM tasks.

  9. Verbal abuse from nurse colleagues and work environment of early career registered nurses.

    Budin, Wendy C; Brewer, Carol S; Chao, Ying-Yu; Kovner, Christine

    2013-09-01

    This study examined relationships between verbal abuse from nurse colleagues and demographic characteristics, work attributes, and work attitudes of early career registered nurses (RNs). Data are from the fourth wave of a national panel survey of early career RNs begun in 2006. The final analytic sample included 1,407 RNs. Descriptive statistics were used to describe the sample, analysis of variance to compare means, and chi square to compare categorical variables. RNs reporting higher levels of verbal abuse from nurse colleagues were more likely to be unmarried, work in a hospital setting, or work in a non-magnet hospital. They also had lower job satisfaction, and less organizational commitment, autonomy, and intent to stay. Lastly, they perceived their work environments unfavorably. Data support the hypothesis that early career RNs are vulnerable to the effects of verbal abuse from nurse colleagues. Although more verbal abuse is seen in environments with unfavorable working conditions, and RNs working in such environments tend to have less favorable work attitudes, one cannot assume causality. It is unclear if poor working conditions create an environment where verbal abuse is tolerated or if verbal abuse creates an unfavorable work environment. There is a need to develop and test evidence-based interventions to deal with the problems inherent with verbal abuse from nurse colleagues. © 2013 Sigma Theta Tau International.

    2009-01-01

    This paper examines the associations between maternal nonstandard work schedules during infancy and children's early behavior problems, and the extent to which infant temperament may moderate these associations. Hypothesized associations were tested using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care (Phase I). Analyses focused on mothers who returned to work by the time the child was 6 months of age, and who worked an average of at least 35 h per week from 6 through 36 months. At 24 and 36 months, children whose mothers worked a nonstandard schedule had higher internalizing and externalizing behaviors. Modest, albeit inconsistent, evidence suggests that temperamentally reactive children may be more vulnerable to maternal work schedules. Maternal depressive symptoms partially mediated associations between nonstandard maternal work schedules and child behavior outcomes. PMID:19233479

  12. Cross-modal activation of auditory regions during visuo-spatial working memory in early deafness.

    Early deafness can reshape deprived auditory regions to enable the processing of signals from the remaining intact sensory modalities. Cross-modal activation has been observed in auditory regions during non-auditory tasks in early deaf subjects. In hearing subjects, visual working memory can evoke activation of the visual cortex, which further contributes to behavioural performance. In early deaf subjects, however, whether and how auditory regions participate in visual working memory remains unclear. We hypothesized that auditory regions may be involved in visual working memory processing and activation of auditory regions may contribute to the superior behavioural performance of early deaf subjects. In this study, 41 early deaf subjects (22 females and 19 males, age range: 20-26 years, age of onset of deafness < 2 years) and 40 age- and gender-matched hearing controls underwent functional magnetic resonance imaging during a visuo-spatial delayed recognition task that consisted of encoding, maintenance and recognition stages. The early deaf subjects exhibited faster reaction times on the spatial working memory task than did the hearing controls. Compared with hearing controls, deaf subjects exhibited increased activation in the superior temporal gyrus bilaterally during the recognition stage. This increased activation amplitude predicted faster and more accurate working memory performance in deaf subjects. Deaf subjects also had increased activation in the superior temporal gyrus bilaterally during the maintenance stage and in the right superior temporal gyrus during the encoding stage. These increased activation amplitude also predicted faster reaction times on the spatial working memory task in deaf subjects. These findings suggest that cross-modal plasticity occurs in auditory association areas in early deaf subjects. These areas are involved in visuo-spatial working memory. Furthermore, amplitudes of cross-modal activation during the maintenance stage were

    Osteoarthritis (OA) is a leading cause of pain and disability, which may be a source of productivity losses. The objectives of this study were to describe the impact of OA, namely through pain and physical disability, on early exit from work and to calculate its economic burden. We analysed data from the national, cross-sectional, population-based EpiReumaPt study (Sep2011-Dec2013) in which 10,661 individuals were randomly surveyed in order to capture all cases of rheumatic diseases. We used all participants aged 50-64, near the official retirement age, who were clinically validated by experienced rheumatologists (n = 1286), including OA cases. A national database was used to calculate productivity values by gender, age and region, using the human capital approach. The impact of OA on the likelihood of early exit from work and the population attributable fractions used to calculate due economic burden (indirect costs) were obtained at the individual level by logistic regression. All results were based on weighted data. Almost one third of the Portuguese population aged 50-64 had OA (29.7%; men: 16.2% and women: 43.5%) and more than half were out of paid work (51.8%). Only knee OA is associated with early exit from work (OR: 2.25; 95%CI: 1.42-3.59; p = 0.001), whereas other OA locations did not reach any statistical difference. Furthermore, we observed an association between self-reported longstanding musculoskeletal pain (OR: 1.55; 95%CI: 1.07-2.23; p = 0.02) and pain interference (OR: 1.35; 95%CI: 1.13-1.62; p = 0.001) with early exit from work. We also detected a clear relationship between levels of disability, measured by the Health Assessment Questionnaire (HAQ), and the probability of work withdrawal. The estimated annual cost of early exit from work attributable to OA was €656 million (€384 per capita; €1294 per OA patient and €2095 per OA patient out-of-work). In this study, we observed an association between OA and early exit from

    Early life stress (ELS) affects stress- reactivity via limbic brain regions implicated such as hippocampus and amygdala. Social support is a major protective factor against ELS effects, while subjects with ELS experience reportedly perceive less of it in their daily life. The workplace, where most adults spend a substantial amount of time in their daily lives, might serve as a major resource for social support. Since previous data demonstrated that social support attenuates stress reactivity, we here used a psychosocial stress task to test the hypothesis that work-related social support modulates the effects of ELS. Results show decreased amygdala reactivity during stress in ELS subjects who report high levels of work- related social support, thereby indicating a signature for reduced stress reactivity. However, this effect was only observable on the neural, but not on the behavioral level, since social support had no buffering effect regarding the subjective experience of stress in daily life as well as regarding feelings of uncontrollability induced by the stress task. Accordingly, our data suggest that subjects with ELS experiences might benefit from interventions targeted at lowering their subjective stress levels by helping them to better perceive the availability of social support in their daily lives.

    We studied how personality moderates the effect of neighbourhood disadvantage on work commitment and unemployment in early adulthood. Using a personality typology of resilients, overcontrollers, and undercontrollers, we hypothesised that the association between neighbourhood poverty and both work commitment and unemployment would be stronger for overcontrollers and undercontrollers than for resilients. We used longitudinal data (N = 249) to test whether the length of exposure to neighbourhood poverty between age 16 and 21 predicts work commitment and unemployment at age 25. In line with our hypothesis, the findings showed that longer exposure was related to weaker work commitment among undercontrollers and overcontrollers and to higher unemployment among undercontrollers. Resilients’ work commitment and unemployment were not predicted by neighbourhood poverty. PMID:27936132

    For many scientific communities, engaging early career researchers is critical for success. These young scientists (graduate students, postdocs, and newly appointed professors) are actively forming collaborations and instigating new research programs. They also stand to benefit hugely from being part of a scientific community, gaining access to career development activities, becoming part of strong collaborator networks, and achieving recognition in their field of study — all of which will help their professional development. There are many ways community leaders can work proactively to support and engage early career scientists, and it it is often a community manager's job to work with leadership to implement such activities. In this presentation, I will outline ways of engaging early career scientists at events and tailored workshops, of promoting development of their leadership skills, and of creating opportunities for recognizing early career scientists within larger scientific communities. In this talk, I will draw from my experience working with the Deep Carbon Observatory Early Career Scientist Network, supported by the Alfred P. Sloan Foundation.

    Partnership working between health and the voluntary and community sector has become an increasing political priority. This paper describes and explores the extent and patterns of partnership working between health and the voluntary and community sector in the context of Early Intervention Services for young people with a first episode of psychosis. Data were collected from 12 Early Intervention Services and through semistructured interviews with 47 voluntary and community sector leads and 42 commissioners across the West Midlands of England. Most partnerships were described as ad hoc and informal in nature although four formal partnerships between Early Intervention Services and voluntary and community sector organizations had been established. Shared agendas, the ability to refer clients onto an organization that could provide a service they could not and shared training facilitated partnership working in this context. Barriers to closer working included differences in culture such as managing risk, the time required to make and maintain relationships and recognition of the advantages of remaining a small and autonomous organization. The four more formal partnerships were also built on the organizations' experience of working together informally, in one case through a specific pilot project. The voluntary and community organizations involved were also branches of larger national organizations for whom finding sustainable funding was less of an issue. In theoretical terms, eight Early Intervention Service: voluntary and community sector partnerships were at a stage of 'pre-partnership collaboration', three at 'partnership creation and consolidation' and one at 'partnership programme delivery'. The empirical data viewed through the lens of the partnership life-cycle model could help early intervention services, and voluntary and community sector professionals better understand where they are, why they are there and the conditions needed to realise the full

    2015-02-01

    Although attentional processes and working memory seem to be significantly involved in the daily activities (particularly during navigating) of persons who are blind and who use these abilities to compensate for their lack of vision, few studies have investigated these mechanisms in this population. The aim of this study is to evaluate the selective, sustained and divided attention, attentional inhibition and switching and working memory of blind persons. Early blind, late blind and sighted participants completed neuropsychological tests that were designed or adapted to be achievable in the absence of vision. The results revealed that the early blind participants outperformed the sighted ones in selective, sustained and divided attention and working memory tests, and the late blind participants outperformed the sighted participants in selective, sustained and divided attention. However, no differences were found between the blind groups and the sighted group in the attentional inhibition and switching tests. Furthermore, no differences were found between the early and late blind participants in this set of tests. These results suggest that early and late blind persons can compensate for the lack of vision by an enhancement of the attentional and working memory capacities. Copyright © 2014 Elsevier B.V.

    Most studies on childhood health and human capital in developing countries examine how early childhood linear growth relates to later human productivity as reflected in schooling success. Work status is another important human capital outcome related to early child health. This study examines the relationship of linear growth restriction at two years of age to work status in young adults who have, for the most part completed their schooling and further explores whether this relationship differs by gender. The analysis sample of 1,795 was drawn from participants in the Cebu Longitudinal Health and Nutrition Survey, which followed individuals from birth to age 20–22 years. Work status in 2005 was represented by three categories: not working, working in an informal job, and working in a formal job. Formal work in the Philippines, as in most countries, is associated with regular hours, higher wages and benefits. Analyses were stratified by gender and current school enrolment, and adjusted for socioeconomic status and attained years of schooling. Among males no longer in school, higher length-for-age Z score (LAZ) at age 2 was associated with a 40% increase in likelihood of formal work compared to not working. In females, each 1 unit increase in LAZ was associated with 0.2 higher likelihood of formal vs. informal work. No significant associations were observed in the small sample of young adults still in school. To improve job prospects of young adults, it is important to provide proper nutrition in early childhood and adequate educational opportunities during schooling years. PMID:19261549

    The development of addition and subtraction accuracy was assessed in first graders with cerebral palsy (CP) in both mainstream (16) and special education (41) and a control group of first graders in mainstream education (16). The control group out-performed the CP groups in addition and subtraction accuracy and this difference could not be fully explained by differences in intelligence. Both CP groups showed evidence of working memory deficits. The three groups exhibited different developmental patterns in the area of early numeracy skills. Children with CP in special education were found to receive less arithmetic instruction and instruction time was positively related to arithmetic accuracy. Structural equation modeling revealed that the effect of CP on arithmetic accuracy is mediated by intelligence, working memory, early numeracy, and instruction time.

    The aims of the study were to examine (i) the association between cardiovascular disease (CVD) or diabetes and exit from paid employment via disability benefits, unemployment, early retirement or other exit routes; and (ii) the impact of work-related factors on exit from paid employment among individuals with CVD or diabetes. Respondents of the longitudinal Survey of Health and Retirement in Europe (SHARE) were included if they were aged >50years, had paid employment at baseline, and a known employment status after 2 or 6years (n=5182). A baseline-interview provided information on the presence of diagnosed CVD and diabetes, and physical and psychosocial work-related factors. During follow-up interviews information on work status was collected. Multinomial regression analyses were used to investigate the association between CVD, diabetes and exit from paid employment, and the impact of work-related factors. Workers with CVD or diabetes had significantly increased probabilities of disability benefits (OR 2.50, 95% CI 1.69-3.70) and early retirement (OR 1.34, 95% CI 1.05-1.74), but a comparable probability of unemployment (OR 1.10, 95% CI 0.71-1.71). Regarding disability benefits, individuals who had a stroke had the highest probability (OR 3.48, 95% CI 1.31-9.23). Perceived high job demands with low rewards or with low control at work further increased the probability of early exit among individuals with CVD or diabetes. Our study shows a prominent role of CVD and diabetes in premature losses to the workforce, and it shows that optimizing psychosocial work-related factors could be beneficial in people with CVD or diabetes.

    To examine whether heavy physical workload in young adulthood increases the risk of local and radiating low back pain (LBP) in midlife. Longitudinal nationally representative Young Finns Study data among women (n=414) and men (n=324), aged 18-24 years in 1986 (baseline), were used. Physical heaviness of work was reported at baseline and follow-up (2007), and local and radiating LBP at follow-up. Covariates were age, smoking and body mass index. Logistic regression was used to examine the associations between physical heaviness of work and LBP. Additionally, the mediating effect of back pain at baseline was examined (the Sobel test). After adjustment for the covariates, and as compared with sedentary/light physical workload, heavy physical workload was associated with radiating LBP among women (OR 4.09, 95% CI 1.62 to 10.31) and men (OR 2.01, 95% CI 1.06 to 3.82). Among men, early back pain mediated the association (p value from the Sobel test=0.006). Among women, early exposure to physically heavy work showed the most consistent associations, while early and late exposures were associated with radiating and local LBP among men. Persistently heavy physical work was associated with radiating LBP among women and men. Physically heavy work at a young age can have a long-lasting effect on the risk of LBP, radiating LBP in particular. These results highlight the need to consider early and persistent exposures to prevent the adverse consequences of physical workload for the low back. Published by the BMJ Publishing Group Limited.

    Few studies have analyzed the relationship between job satisfaction and return to work (RTW) in cardiac patients. The aim of this paper was to investigate whether job satisfaction predicted early RTW in patients sick listed after cardiac invasive procedures. A 6-month prospective study was carried out in a sample of 83 patients in working age who had recently been treated with angioplasty or cardiac surgery. Job satisfaction was measured using the scale from the Occupational Stress Indicator during cardiac rehabilitation. Time to RTW was assessed at the 6-month occupational physician examination. Logistic regression analyses were used to study the association between job satisfaction at baseline and early RTW at follow-up, adjusted for socio-demographic, medical (type of cardiac intervention, ejection fraction) and psychological (depression, locus of control, illness perception) factors. Participants with high job satisfaction were more likely to return early to work, with an odds ratio (OR) of 5.92 (95 % CI, 1.69-20.73) in the most-adjusted model, compared to participants with low job satisfaction. Satisfaction with organizational processes was the job satisfaction component most strongly associated with early RTW (OR, 4.30; 95 % CI, 1.21-15.03). To the best of our knowledge, this is the first prospective study that investigated whether job satisfaction predicts time to RTW after cardiac interventions. The results suggested that when patients are satisfied with their job and positively perceived their work environment, they will be more likely to early RTW, independently of socio-demographic, medical and psychological factors.

    We examine how work difficulties in the early career, and the generally deteriorating work conditions associated with the recent U.S. economic recession, shape individuals’ work values. Drawing on panel data from the Youth Development Study, we test whether individuals change their work values in response to concerns about satisfying material needs or the features of jobs that they are able to attain. Results indicate that extrinsic values are weakened in the face of unemployment, as well as reduced job security, income, and advancement. These patterns support a reinforcement and accentuation model in which workers adjust their values to emphasize what they actually obtain from the job. Intrinsic values are weakened by working in a job unrelated to one’s career plans; they are reinforced by the experience of greater intrinsic rewards and advancement opportunities. PMID:23503050

    2017-01-01

    Sustained and elevated activity during the working memory delay period has long been considered the primary neural correlate for maintaining information over short time intervals. This idea has recently been reinterpreted in light of findings generated from multiple neural recording modalities and levels of analysis. To further investigate the sustained or transient nature of activity, the temporal-spectral evolution (TSE) of delay period activity was examined in humans with high density EEG during performance of a Sternberg working memory paradigm with a relatively long six second delay and with novel scenes as stimuli. Multiple analyses were conducted using different trial window durations and different baseline periods for TSE computation. Sensor level analyses revealed transient rather than sustained activity during delay periods. Specifically, the consistent finding among the analyses was that high amplitude activity encompassing the theta range was found early in the first three seconds of the delay period. These increases in activity early in the delay period correlated positively with subsequent ability to distinguish new from old probe scenes. Source level signal estimation implicated a right parietal region of transient early delay activity that correlated positively with working memory ability. This pattern of results adds to recent evidence that transient rather than sustained delay period activity supports visual working memory performance. The findings are discussed in relation to synchronous and desynchronous intra- and inter-regional neural transmission, and choosing an optimal baseline for expressing temporal-spectral delay activity change.

    Musculoskeletal disorders (MSDs) are a common source of work disability. Opioid prescribing for MSDs has been on the rise, despite a lack of data on effectiveness. The objective of this study was to conduct a systematic review to determine whether early receipt of opioids is associated with future work outcomes among workers with MSDs compared with other analgesics, no analgesics, or placebo. MEDLINE, EMBASE, CINAHL, and CENTRAL were searched from inception to 2014 and reference lists were scanned. Studies were included if opioids were prescribed within 12 weeks of MSD onset. Eligible outcomes included absenteeism, work status, receiving disability payments, and functional status. Two reviewers independently reviewed articles for relevance, risk of bias, and data extraction using standardized forms. Data synthesis using best evidence synthesis methods was planned. Five historical cohort studies met the inclusion criteria, all including workers filing wage compensation claims. Four studies demonstrated a significant association between early opioids and prolonged work disability. One study found a shorter time between prescriptions to be associated with shorter work disability. However, all studies were found to be at a high risk of bias and a best evidence synthesis could not be conducted. The main limitations identified were with exposure measurement and control of confounding. Current literature suggests that opioids provided within the first 12 weeks of onset of an MSD are associated with prolonged work disability. However, the conclusions of these studies need testing in a high-quality study that addresses the methodological shortcomings identified in the current review.

    To determine whether an association exists between shift work and early reproductive outcomes. MEDLINE, Embase, and Web of Science were searched. Additional sources included Google Scholar, the Cochrane Library, online publications of national colleges, the ClinicalTrials.gov, and references of retrieved papers. Included studies compared female shift workers (work outside 8:00 AM to 6:00 PM) with nonshift workers with menstrual disruption (cycles less than 25 days or greater than 31 days), infertility (time-to-pregnancy exceeding 12 months), or early spontaneous pregnancy loss (less than 25 weeks). Two reviewers extracted adjusted and raw data. Random effect models were used to pool data weighting for the inverse of variance. Assessments of heterogeneity, bias, and subgroup analyses were performed. Sixteen independent cohorts from 15 studies (123,403 women) were subject to analysis. Shift workers had increased rates of menstrual disruption (16.05% [2,207/13,749] compared with 13.05% [7,561/57,932] [n=71.681, odds ratio {OR} 1.22, 95% confidence interval {CI} 1.15-1.29, I 0%]) and infertility (11.3% [529/4,668] compared with 9.9% [2,354/23,811] [OR 1.80, 95% CI 1.01-3.20, I 94%]) but not early spontaneous pregnancy loss (11.84% [939/7,931] compared with 12.11% [1,898/15,673] [n=23,604, OR 0.96, 95% CI 0.88-1.05, I 0%]). Night shifts were associated with increased early spontaneous pregnancy loss (n=13,018, OR 1.29, 95% CI 1.11-1.50, I 0%). Confounder adjustment led to persistent relationships between shift work and menstrual disruption (adjusted OR 1.15, 95% CI 1.01-1.31, I 70%) but not infertility (adjusted OR 1.11 95% CI 0.86-1.44, I 61%). The association between night shifts and early spontaneous pregnancy loss remained (adjusted OR 1.41 95% CI 1.22-1.63, I 0%). This review provides evidence for an association between performing shift work and early reproductive outcomes, consistent with later pregnancy findings. However, there is currently insufficient evidence

    The purpose of this study was to assess the effects of early part-time sick leave on return to work (RTW) and sickness absence among patients with musculoskeletal disorders. A randomized controlled trial was conducted in six occupational health units of medium- and large-size enterprises. Patients aged 18-60 years with musculoskeletal disorders (N=63) unable to perform their regular work were randomly allocated to part- or full-time sick leave. In the former group, workload was reduced by restricting work time by about a half. Remaining work tasks were modified when necessary, as specified in a "fit note" from the physician. The main outcomes were time to return to regular work activities and sickness absence during 12-month follow-up. Time to RTW sustained for ≥4 weeks was shorter in the intervention group (median 12 versus 20 days, P=0.10). Hazard ratio of RTW adjusted for age was 1.60 [95% confidence interval (95% CI) 0.98-2.63] and 1.76 (95% CI 1.21-2.56) after further adjustment for pain interference with sleep and previous sickness absence at baseline. Total sickness absence during the 12-month follow-up was about 20% lower in the intervention than the control group. Compliance with the intervention was high with no discontinuations of part-time sick leave due to musculoskeletal reasons. Early part-time sick leave may provide a faster and more sustainable return to regular duties than full-time sick leave among patients with musculoskeletal disorders. This is the first study to show that work participation can be safely increased with early part-time sick leave.

    PubMed

    West, Marcus

    2016-02-01

    This paper outlines a view of early relational trauma as underlying borderline states of mind, and argues that Knox's paper on internal working models and the complex provides a basis for understanding such states of mind. The author argues that in addition to internal working models, the complex also embodies and contains primitive defences of the core self. He outlines how these apply on the objective, subjective, transference and archetypal levels, and in direct and reversed forms and applies this to the account of Fordham's analysis of his patient 'K', which ended in impasse. The paper explores the dynamic that emerged in that analysis and suggests that it could be helpfully accounted for in terms of the co-construction and re-construction of early relational trauma in the analytic relationship. © 2016, The Society of Analytical Psychology.

    Huntington's disease (HD) is a progressive and fatal neurodegenerative disorder caused by a polyglutamine expansion in the gene encoding the protein huntingtin. The disease progresses over decades, but often patients develop cognitive impairments that precede the onset of the classical motor symptoms. Similar to the disease progression in humans, the yeast artificial chromosome (YAC) 128 HD mouse model also exhibits cognitive dysfunction that precedes the onset of the neuropathological and motor impairments characteristic of HD. Thus, the purpose of this study was to evaluate whether short- and long-term synaptic plasticity in the hippocampus, two related biological models of learning and memory processes, were altered in YAC128 mice in early stages of disease progression. We show that the YAC128 hippocampal dentate gyrus (DG) displays marked reductions in paired-pulse depression both at 3 and 6 months of age. In addition, significantly enhanced post-tetanic and short-term potentiation are apparent in YAC128 mice after high-frequency stimulation at this time. Early and late forms of long-term plasticity were not altered at this stage. Together these findings indicate that there may be elevated neurotransmitter release in response to synaptic stimulation in YAC128 mice during the initial phase of disease progression. These abnormalities in short-term plasticity detected at this stage in YAC128 HD transgenic mice indicate that aberrant information processing at the level of the synapses may contribute, at least in part, to the early onset of cognitive deficits that are characteristic of this devastating neurodegenerative disorder.

    We analyzed the immediate-early transactivator Rta of Epstein-Barr virus (EBV) for its role as a target for specific cytotoxic T lymphocytes (CTL). Panels of overlapping peptides covering the entire amino acid sequence of Rta were synthesized and used to induce and analyze specific CTL responses in EBV-positive donors. Using peptide-pulsed target cells, we found nine different CTL epitopes that are distributed over the entire protein sequence. One epitope restricted by HLA-A24 could be mapped to the decameric sequence DYCNVLNKEF between amino acid positions 28 and 37 of the Rta protein. A second epitope could be assigned to the same region of Rta (residues 25 to 39) and was shown to be restricted by HLA-B18. Another, minimal epitope could be mapped to the nonameric sequence ATIGTAMYK between amino acid positions 134 and 142; this peptide was restricted by HLA-A11. Another four epitopes were proven to be restricted by HLA-A2, -A3, -B61, and -Cw4 and were located between Rta residues 225 and 239, 145 and 159, 529 and 543, and 393 and 407, respectively. For two other epitopes, only the location within the Rta protein is known so far (residues 121 to 135 and 441 to 455); their exact HLA restriction patterns have not yet been identified. Using target cells infected with recombinant vaccinia virus containing the gene for Rta, we showed that six of eight Rta-specific CTL lines recognized the corresponding peptides also after endogenous processing. These data suggest that Rta comprises an important target for EBV-specific cellular cytotoxicity. Together with recent findings of other immediate-early and early proteins also acting as CTL targets, they reveal the role of proteins of the lytic cycle in the immune recognition of EBV-infected cells.

    2018-03-01

    The rising number of parents who work nonstandard schedules has led to a growing body of research concerned with what this trend means for children. The negative outcomes for children of parents who work nonstandard schedules are thought to arise from the disruptions these schedules place on family life, and thus, the types of parenting that support their children's development, particularly when children are young. Using a nationally representative sample of two-parent families (Early Childhood Longitudinal Study-Birth cohort, n = 3,650), this study examined whether mothers' and their partners' nonstandard work schedules were associated with mothers' parenting when children were 2 and 4 years old. Structural equation models revealed that mothers' and their partners' nonstandard work schedules were associated with mothers' lower scores on measures of positive and involved parenting. These associations were mediated by fathers' lower levels of participation in cognitively supportive parenting and greater imbalance in cognitively supportive tasks conducted by mothers versus fathers.

    Previous studies on maternal work hours and child diet quality have reported conflicting findings possibly due to differences in study design, lack of a comprehensive measure of diet quality and differing ages of the children under investigation. The present study aimed to prospectively examine the impact of parental work hours from age 1 year to age 14 years on adolescent diet quality. Multivariate linear regression models were used to examine independent associations between parents' work hours at each follow-up and across 14 years and adolescent diet quality at age 14 years. A diet quality index was based on the international literature and Australian recommendations, consisting of six food groups and nine nutrients. Perth, Western Australia. Children (n 1629) participating in the Western Australian Pregnancy Cohort (Raine) Study. Compared with children of mothers in full-time employment, children of mothers who were not employed in early childhood up to age 5 years had a higher average diet quality score at age 14 years, independent of maternal and family socio-economic status. Across 14 years the number of years the mother worked full time and increasing average weekly hours were associated with lower diet quality. Father's work hours had little association with adolescent diet quality. Having a mother stay at home in early to middle childhood is associated with better diet quality in adolescence. Support may be beneficial for families where the mother returns to full-time employment before the child reaches 8 years of age.

  15. Physiological optics, cognition and emotion: a novel look at the early work of Wilhelm Wundt.

    PubMed

    Wassmann, Claudia

    2009-04-01

    The German physiologist Wilhelm Wundt, who later founded experimental psychology, arguably developed the first modern scientific conception of emotion. In the first edition of Vorlesungen über die Menschen- und Thierseele (Lectures on human and animal psychology), which was published in 1863, Wundt tried to establish that emotions were essential parts of rational thought. In fact, he considered them unconscious steps of decision-making that were implied in all processes of conscious thought. His early work deserves attention not only because it is the attempt to conceptualize cognition and emotion strictly from a neural point of view but also because it represents the very foundation of the debate about the nature of emotion that revolved around William James' theory of emotion during the 1890s. However, this aspect of his work is little known because scholars who have analyzed Wundt's work focused on his late career. Furthermore, historical analysis interpreted Wundt's work within a philosophical framework, rather than placing it in the context of German medical and physiological research in which it belongs. In addition, Wundt's early works are hardly available to an English speaking audience because they were never translated.

    Increasing anthropogenic activities in the Arctic represent an enhanced threat for oil pollution in a marine environment that is already at risk from climate warming. In particular, this applies to species with free-living pelagic larvae that aggregate in surface waters and under the sea ice where hydrocarbons are likely to remain for extended periods of time due to low temperatures. We exposed the positively buoyant eggs of polar cod (Boreogadus saida), an arctic keystone species, to realistic concentrations of a crude oil water-soluble fraction (WSF), mimicking exposure of eggs aggregating under the ice to oil WSF leaking from brine channels following encapsulation in ice. Total hydrocarbon and polycyclic aromatic hydrocarbon levels were in the ng/L range, with most exposure concentrations below the limits of detection throughout the experiment for all treatments. The proportion of viable, free-swimming larvae decreased significantly with dose and showed increases in the incidence and severity of spine curvature, yolk sac alterations and a reduction in spine length. These effects are expected to compromise the motility, feeding capacity, and predator avoidance during critical early life stages for this important species. Our results imply that the viability and fitness of polar cod early life stages is significantly reduced when exposed to extremely low and environmentally realistic levels of aqueous hydrocarbons, which may have important implications for arctic food web dynamics and ecosystem functioning.

    The present study aimed to investigate the long-term effect of 1976 Tangshan earthquake exposure in early life on performance of working memory in adulthood. A total of 907 study subjects born and raised in Tangshan were enrolled in this study. They were divided into three groups according to the dates of birth: infant exposure (3-12 months, n=274), prenatal exposure (n=269), and no exposure (born at least 1 year after the earthquake, n=364). The prenatal group was further divided into first, second, and third trimester subgroups based on the timing of exposure during pregnancy. Hopkins Verbal Learning Test-Revised and Brief Visuospatial Memory Test-Revised (BVMT-R) were used to measure the performance of working memory. Unconditional logistic regression analysis was used to analyze the influential factors for impaired working memory. The Hopkins Verbal Learning Test-Revised scores did not show significant difference across the three groups. Compared with no exposure group, the BVMT-R scores were slightly lower in the prenatal exposure group and markedly decreased in the infant exposure group. When the BVMT-R scores were analyzed in three subgroups, the results showed that the subjects whose mothers were exposed to earthquake in the second and third trimesters of pregnancy had significantly lower BVMT-R scores compared with those in the first trimester. Education level and early-life earthquake exposure were identified as independent risk factors for reduced performance of visuospatial memory indicated by lower BVMT-R scores. Infant exposure to earthquake-related stress impairs visuospatial memory in adulthood. Fetuses in the middle and late stages of development are more vulnerable to stress-induced damage that consequently results in impaired visuospatial memory. Education and early-life trauma can also influence the performance of working memory in adulthood.

    There has been a growing concern that maternal employment could have adverse or beneficial effects on children's health. Although recent studies demonstrated that maternal employment was associated with a higher risk of childhood overweight, the evidence remains sparse in Asian countries. We sought to examine the relationship between maternal working hours and early childhood overweight in a rural town in Okayama Prefecture. In February 2008, questionnaires were sent to parents of all preschool children aged ≥3 yr in the town to assess maternal working status (working hours and form of employment), children's body mass index, and potential confounders. Childhood overweight was defined following the age and sex-specific criteria of the International Obesity Task Force. Odds ratios (ORs) and 95% confidence intervals (CIs) for childhood overweight were estimated in a logistic regression. We used generalized estimating equations with an exchangeable correlation matrix, considering the correlation between siblings. We analyzed 364 preschool children. Adjusting for each child's characteristics (age, sex), mother's characteristics (age, obesity, educational attainment, smoking status, and social participation), and family's characteristics (number of siblings), children whose mothers work <8 h/day had a substantially lower risk for being overweight (OR: 0.28, 95% CI: 0.09, 0.93) compared with children of non-working mothers, whereas the relationship was less pronounced among children whose mothers work ≥8 h/day (OR: 0.71, 95% CI: 0.19, 2.68). We observed similar patterns in a stratified analysis by the form of maternal employment. Short maternal working hours are associated with a lower odds of early childhood overweight.

    Data describing factors associated with work-life balance, burnout, and career and life satisfaction for early career pediatricians are limited. We sought to identify personal and work factors related to these outcomes. We analyzed 2013 survey data of pediatricians who graduated residency between 2002 and 2004. Dependent variables included: (1) balance between personal and professional commitments, (2) current burnout in work, (3) career satisfaction, and (4) life satisfaction. Multivariable logistic regression examined associations of personal and work characteristics with each of the 4 dependent variables. A total of 93% of participants completed the survey (n = 840). A majority reported career (83%) and life (71%) satisfaction. Fewer reported current appropriate work-life balance (43%) or burnout (30%). In multivariable modeling, excellent/very good health, having support from physician colleagues, and adequate resources for patient care were all found to be associated with a lower prevalence of burnout and a higher likelihood of work-life balance and career and life satisfaction. Having children, race, and clinical specialty were not found to be significantly associated with any of the 4 outcome measures. Female gender was associated with a lower likelihood of balance and career satisfaction but did not have an association with burnout or life satisfaction. Burnout and struggles with work-life balance are common; dissatisfaction with life and career are a concern for some early career pediatricians. Efforts to minimize these outcomes should focus on encouragement of modifiable factors, including health supervision, peer support, and ensuring sufficient patient care resources.

    Background Up to 30% of recently diagnosed MS patients lose their jobs in the first four years after diagnosis. Taking into account the personal and socio-economic importance of sustaining employment, it is of the utmost importance to examine factors involved with work participation. Objective To investigate differences in self-reported functioning in recently diagnosed MS patients with and without a paid job. Methods Self-reports of physical and cognitive functioning, depression, anxiety and fatigue were gathered from 44 relapsing-remitting MS patients diagnosed within 3 years. Results Patients with a paid job (57%) reported better physical functioning (p<0.001), better memory functioning (p = 0.01) and a lower physical impact of fatigue (p = 0.018) than patients without a paid job. Physical functioning was the main predictor of employment status in a logistic regression model. In those with a paid job better memory functioning (r = 0.54, p = 0.005) and a lower social impact of fatigue (r = −0.46, p = 0.029) correlated with an increased number of working hours. Conclusion Better physical functioning is the primary factor involved with increased work participation in early MS. Better self-reported memory functioning and less social fatigue were associated with increased working hours. These findings highlight the importance of battling these symptoms in the early stages of MS. PMID:25153710

    The link between money and motivation has been a debated topic for decades, especially in work organizations. However, field studies investigating the amount of pay in relation to employee motivation is lacking and there have been calls for empirical studies addressing compensation systems and motivation in the work domain. The purpose of this study was to examine outcomes associated with the amount of pay, and perceived distributive and procedural justice regarding pay in relation to those for perceived managerial need support. Participants were 166 bank employees who also reported on their basic psychological need satisfaction and intrinsic work motivation. SEM-analyses tested a self-determination theory (SDT) model, with satisfaction of the competence and autonomy needs as an intervening variable. The primary findings were that amount of pay and employees' perceived distributive justice regarding their pay were unrelated to employees' need satisfaction and intrinsic work motivation, but procedural justice regarding pay did affect these variables. However, managerial need support was the most important factor for promoting need satisfaction and intrinsic work motivation both directly, indirectly, and as a moderator in the model. Hence, the results of the present organizational field study support earlier laboratory experiments within the SDT framework showing that monetary rewards did not enhance intrinsic motivation. This seems to have profound implications for organizations concerned about motivating their employees. © 2015 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  4. Early top-down control of visual processing predicts working memory performance

    Selective attention confers a behavioral benefit for both perceptual and working memory (WM) performance, often attributed to top-down modulation of sensory neural processing. However, the direct relationship between early activity modulation in sensory cortices during selective encoding and subsequent WM performance has not been established. To explore the influence of selective attention on WM recognition, we used electroencephalography (EEG) to study the temporal dynamics of top-down modulation in a selective, delayed-recognition paradigm. Participants were presented with overlapped, “double-exposed” images of faces and natural scenes, and were instructed to either remember the face or the scene while simultaneously ignoring the other stimulus. Here, we present evidence that the degree to which participants modulate the early P100 (97–129 ms) event-related potential (ERP) during selective stimulus encoding significantly correlates with their subsequent WM recognition. These results contribute to our evolving understanding of the mechanistic overlap between attention and memory. PMID:19413473

    Aims 1) To evaluate the role of pre-existing weakness in working memory ability (WM) as a risk factor for early alcohol use as mediated by different forms of impulsivity. 2) To assess the adverse effects of progressive alcohol use on variations in WM over time. Design, Setting and Participants A community sample of 358 adolescents [48% males, Meanage(baseline) = 11.4± 0.87 years] from a longitudinal cohort design, assessed annually over four consecutive years with less than 6% attrition. Measurements Repeated assessments were conducted for the following key variables: WM (based on performance on four separate tasks), frequency of alcohol use (AU), and three forms of impulsivity, namely sensation seeking (SS), acting-without-thinking (AWT) and delay discounting (DD). Latent growth curve modeling procedures were used to identify individual trajectories of change for all key variables. Findings Weakness in WM (at baseline) significantly predicted both concurrent alcohol use and increased frequency of use over the four waves (p <.05). This effect was entirely mediated by two forms of impulsivity, AWT and DD, both of which were characterized by underlying weakness in WM. No individual variation was observed in the slopes of WM, which suggests that individual variations in alcohol use were not associated with changes in WM in our early adolescent sample. Conclusions Early adolescent alcohol use may be a consequence of (pre-existing) weaknesses in working memory (WM) rather than a cause of it. Efforts to reduce early alcohol use should consider the distinct roles of different impulsivity dimensions, in addition to WM, as potential targets of intervention. PMID:23033972

    Given the challenge of a high proportion of older employees who retire early from work we analyse associations of indicators of a poor psychosocial quality of work with intended premature departure from work in a large sample of older male and female employees in 10 European countries. Baseline data from the 'Survey of Health, Ageing and Retirement in Europe' (SHARE) were obtained from 3523 men and 3318 women in 10 European countries. Data on intended early retirement, four measures of well-being (self-rated health, depressive symptoms, general symptom load, and quality of life), and quality of work (effort-reward imbalance; low control at work) were obtained from structured interviews and questionnaires. Country-specific and total samples are analysed, using logistic regression analysis. Poor quality of work is significantly associated with intended early retirement. After adjustment for well-being odds ratios (OR) of effort-reward imbalance [OR 1.72 (1.43-2.08)] and low control at work [OR 1.51 (1.27-1.80)] on intended early retirement are observed. Poor quality of work and reduced well-being are independently associated with the intention to retire from work. The consistent association of a poor psychosocial quality of work with intended early retirement among older employees across all European countries under study calls for improved investments into better quality of work, in particular increased control and an appropriate balance between efforts spent and rewards received at work.

    To assess if a change in disease activity is associated with a change in work productivity loss (WPL) over 1 year in early axial SpA (axSpA) patients. Baseline and 1 year data of axSpA patients in the SPondyloArthritis Caught Early cohort were analysed. Linear regression models were built explaining the change in the Ankylosing Spondylitis Disease Activity Score (ASDAS) over time by the change in absenteeism, presenteeism, WPL and activity impairment over time. Effect modification and confounding were tested for age, gender, arm of Assessment of SpondyloArthritis international Society classification criteria, HLA-B27, duration of chronic back pain, profession and medication. At baseline, in 105 axSpA patients (48% female, mean age 30.8 years, mean symptom duration 13.6 months, 92% HLA-B27 positive, 24% radiographic sacroiliitis), the mean ASDAS was 2.4 (s.d. 1.0), absenteeism 9% (s.d. 23), presenteeism 33% (s.d. 28), WPL 36% (s.d. 30) and activity impairment 37% (s.d. 25). After 1 year, the mean ASDAS decreased to 2.0 (s.d. 0.8) and absenteeism, presenteeism, WPL and activity impairment improved to 6% (s.d. 22), 26% (s.d. 26), 27% (s.d. 29) and 27% (s.d. 26), respectively. Models showed that if ASDAS decreased 1 unit, absenteeism, presenteeism, WPL and activity impairment improved by 5, 17, 16 and 18%, respectively. The impact of disease activity on work productivity was higher in patients with shorter symptom duration and the impact on absenteeism was higher in patients starting pharmacological treatment. In early axSpA patients, work productivity and daily activities are seriously impacted at baseline and 1 year. However, decreasing disease activity is associated with marked improvements in work productivity and daily activities. © The Author 2017.

    The association between different types of physical activity and fear-avoidance beliefs remains unclear. This study investigates the association between work-related and leisure-time physical activity with fear-avoidance beliefs in the general working population. Currently employed wage earners (n=10,427) from the 2010 round of the Danish Work Environment Cohort Study replied to questions about work, lifestyle and health. General linear models controlling for lifestyle, psychosocial work factors, education, pain, medication-use and chronic diseases tested associations of work-related and leisure-time physical activity (explanatory variables) with fear-avoidance beliefs (outcome variable, scale 0-100). The level of fear-avoidance was 41.7 (SD 27.3), 38.0 (SD 26.9) and 54.3 (SD 27.7) among the general working population, a subgroup of pain-free individuals, and a subgroup with back disease, respectively. In the general working population, the level of fear-avoidance among those with low, moderate and high physical activity during leisure were 47 [95% confidence intervals (CI) 45-49], 44 (95% CI 42-46) and 43 (95% CI 41-45), and physical activity at work were 40 (95% CI 39-42), 44 (95% CI 42-46) and 49 (95% CI 48-51), respectively. Individuals with back disease and a high level of physical activity at work showed the overall highest level of fear-avoidance whereas pain-free individuals with a low level of physical activity at work showed the overall lowest level of fear-avoidance. Physical activity during work and leisure shows contrasting associations with fear-avoidance beliefs. While high physical activity during leisure is associated with lower levels, high physical activity at work is associated with higher levels of fear-avoidance. The present results may reflect some deeply rooted negative beliefs about pain and work in the population. On the societal level, campaigns may be a possible way forward as these have shown to improve beliefs about musculoskeletal

    The past decade has seen significant changes to the face of neurosurgical training in the United Kingdom, driven in part by an increasing focus on patient safety and the introduction of Modernising Medical Careers and the European Working Time Directive (EWTD). Recent reforms to neurosurgical training over the past few years have resulted in creation of an 8-year 'run-through' training programme. In this programme, early years (ST1 and ST2) trainees often lack dedicated time for elective theatre lists and outpatient clinics. Further, any time spent in theatre and clinics is often with different teams. Here we describe a training model for early years trainees at the National Hospital for Neurology and Neurosurgery, who are given the responsibilities traditionally associated with a more senior trainee including dedicated weekly theatre and clinic time under the supervision of a single consultant, in addition to out of hours experience. The advantages and considerations for implementing this model are discussed, including the benefit of guidance under a single consultant in the early stages of training, along with key educational concepts necessary for understanding its utility. We feel that this is an effective model for junior neurosurgical training in the EWTD era, expediting the trainee's development of key technical and non-technical skills, with potentially significant rewards for patient, trainee and trainer. National implementation of this model should be considered.

    To test whether chronic work stress is accompanied by altered immune functioning, changes in lymphocyte subsets and in lymphocyte production of cytokines were examined in reaction to acute psychosocial stress. Work stress was measured according to Siegrist's effort-reward-imbalance (ERI) model. ERI reflects stress due to a lack of reciprocity between costs and gains at work. Overcommitment (OC) is conceptualized as a dysfunctional coping pattern mainly characterized by the inability to withdraw from work obligations. Fifty-five healthy teachers (34 women, 21 men, mean age 50.0 ± 8.47 years) were exposed to a standardized laboratory stressor (Trier Social Stress Test). Lymphocyte subset counts and lymphocyte production of tumor-necrosis-factor (TNF)-α, interferon (IFN)-γ, interleukin (IL)-2, -4, -6 and -10 were measured before and after challenge. High levels of ERI and OC were associated with lower natural killer (NK) cell (CD16+/56+) numbers whereas high levels of OC were related to a lower increase in T-helper cells (CD4+) after stress. Furthermore, subjects with higher ERI showed an overall increased pro-inflammatory activity, with higher TNF-α production at both time points and elevated pre-stress IL-6 production. IL-10 production decreased with higher ERI after stress. The ratios of TNF-α/IL-10 and IL-6/IL-10 were significantly increased in subjects high on ERI. Finally, OC was associated with higher IL-2 production post-stress. The present findings suggest a dampened innate immune defence, reflected in lower NK cell numbers together with an increased pro-inflammatory activity in teachers high on ERI and OC. Such pathways could partly be responsible for the increased vulnerability for stress-related diseases in individuals suffering from chronic work stress. Copyright © 2010 Elsevier Inc.

  13. Learning to File: Reconfiguring Information and Information Work in the Early Twentieth Century.

    PubMed

    Robertson, Craig

    2017-01-01

    This article uses textbooks and advertisements to explore the formal and informal ways in which people were introduced to vertical filing in the early twentieth century. Through the privileging of "system" an ideal mode of paperwork emerged in which a clerk could "grasp" information simply by hand without having to understand or comprehend its content. A file clerk's hands and fingers became central to the representation and teaching of filing. In this way, filing offered an example of a distinctly modern form of information work. Filing textbooks sought to enhance dexterity as the rapid handling of paper came to represent information as something that existed in discrete units, in bits that could be easily extracted. Advertisements represented this mode of information work in its ideal form when they frequently erased the worker or reduced him or her to hands, as "instant" filing became "automatic" filing, with the filing cabinet presented as a machine.

    In order to stop the trend towards early retirement in Germany a law to promote partial retirement recently has been passed by parliament. Concerning the impact on the labour market the raising of the pension age for older unemployed which is fixed in this law has to be seen as contraproductive and it will deteriorate the financial situation of unemployed older workers. Concerning the implementation of partial-retirement as such, there are momentous obstacles to realize part-time working arrangements in practice: the insufficient financial compensation for older workers and the obligation for employers to hire unemployed workers. Supplementary collective agreements are seen to be necessary to establish part-time work for older workers.

    Many women temporarily reduce work hours or stop working when caring for small children. However, mothers of children with special health care needs may face particular challenges balancing childrearing responsibilities and employment demands. This study examines how the work participation among mothers of children with special health care needs compares with that of mothers in general during early motherhood, focusing in particular on the extent of the child's additional health care needs. By linkage of the population-based Norwegian Mother and Child Cohort Study with national registers on employment, child health care needs, and social background factors, 41,255 mothers employed prior to childbirth were followed until child age 3 years to investigate associations between the child's care needs and mother's dropping out of employment. In total, 16.3% of the formerly employed mothers were no longer employed at child age 3 years. Mothers of children with mild care needs did not differ from mothers in general, whereas mothers of children with moderate [Risk Ratio (RR) 1.45; 95% confidence interval (CI) 1.17, 1.80] and severe care needs [RR 2.19; 95% CI 1.67, 2.87] were at substantial risk of not being employed at follow-up. The impact of the child's health care needs remained strong also after adjusting for several factors associated with employment in general. Extensive childhood health care needs are associated with reduced short-term employment prospects and remain a substantial influence on mothers' work participation during early motherhood, irrespective of other important characteristics associated with maternal employment. © 2013 John Wiley & Sons Ltd.

  16. Balancing life and work by unbending gender: Early American women psychologists' struggles and contributions.

    2017-07-01

    Women's participation in the work force shifted markedly throughout the twentieth century, from a low of 21 percent in 1900 to 59 percent in 1998. The influx of women into market work, particularly married women with children, put pressure on the ideology of domesticity: an ideal male worker in the outside market married to a woman taking care of children and home (Williams, 2000). Here, we examine some moments in the early-to-mid-twentieth century when female psychologists contested established norms of life-work balance premised on domesticity. In the 1920s, Ethel Puffer Howes, one of the first generation of American women psychologists studied by Scarborough and Furumoto (1987), challenged the waste of women's higher education represented by the denial of their interests outside of the confines of domesticity with pioneering applied research on communitarian solutions to life-work balance. Prominent second-generation psychologists, such as Leta Hollingworth, Lillian Gilbreth, and Florence Goodenough, sounded notes of dissent in a variety of forums in the interwar period. At mid-century, the exclusion of women psychologists from war work galvanized more organized efforts to address their status and life-work balance. Examination of the ensuing uneasy collaboration between psychologist and library scholar Alice Bryan and the influential male gatekeeper E. G. Boring documents gendered disparities in life-work balance and illuminates how the entrenched ideology of domesticity was sustained. We conclude with Jane Loevinger's mid-century challenge to domesticity and mother-blaming through her questioning of Boring's persistent focus on the need for job concentration in professional psychologists and development of a novel research focus on mothering. © 2017 Wiley Periodicals, Inc.

  17. Construction of Early and Midlife Work Trajectories in Women and Their Association With Birth Weight

    2014-01-01

    Objectives. We derived trajectories of the substantive complexity (SC) of work across mid-adult life in women and determined their association with term birth weight. SC is a concept that encompasses decision latitude, active learning, and ability to use and expand one’s abilities at work. Methods. Using occupational data from the National Longitudinal Survey of Youth 1979 and O*NET work variables, we used growth mixture modeling (GMM) to construct longitudinal trajectories of work SC from the ages of 18 to 34 years. The association between work trajectories and birth weight of infants born to study participants was modeled using generalized estimating equations, adjusting for education, income, and relevant covariates. Results. GMM yielded a 5-class solution for work trajectories in women. Higher work trajectories were associated with higher term birth weight and were robust to the inclusion of both education and income. A work trajectory that showed a sharp rise after age 24 years was associated with marked improvement in birth weight. Conclusions. Longitudinal modeling of work characteristics might improve capacity to integrate occupation into a life-course model that examines antecedents and consequences for maternal and child health.

    We propose a new method for the early detection of metabolic syndrome in the working population, which was free of biomarkers (non-invasive) and based on anthropometric variables, and to validate it in a new working population. Prevalence studies and diagnostic test accuracy to determine the anthropometric variables associated with metabolic syndrome, as well as the screening validity of the new method proposed, were carried out between 2013 and 2015 on 636 and 550 workers, respectively. The anthropometric variables analysed were: blood pressure, body mass index, waist circumference, waist-height ratio, body fat percentage and waist-hip ratio. We performed a multivariate logistic regression analysis and obtained receiver operating curves to determine the predictive ability of the variables. The new method for the early detection of metabolic syndrome we present is based on a decision tree using chi-squared automatic interaction detection methodology. The overall prevalence of metabolic syndrome was 14.9%. The area under the curve for waist-height ratio and waist circumference was 0.91 and 0.90, respectively. The anthropometric variables associated with metabolic syndrome in the adjusted model were waist-height ratio, body mass index, blood pressure and body fat percentage. The decision tree was configured from the waist-height ratio (⩾0.55) and hypertension (blood pressure ⩾128/85 mmHg), with a sensitivity of 91.6% and a specificity of 95.7% obtained. The early detection of metabolic syndrome in a healthy population is possible through non-invasive methods, based on anthropometric indicators such as waist-height ratio and blood pressure. This method has a high degree of predictive validity and its use can be recommended in any healthcare context. © The European Society of Cardiology 2016.

Methods All consecutive cervical cancer patients who presented at our tertiary referral center in the Netherlands (January 2006 – September 2013), and for whom ≥6 months follow-up was available, were included. As part of the staging procedure, patients underwent a routine two-directional digital chest radiograph. Findings were compared to a composite reference standard consisting of all imaging studies and histology obtained during the 6 months following radiography. Results Of the 402 women who presented with cervical cancer, 288 (71.6%) underwent chest radiography and had ≥6 months follow-up. Early clinical stage (I/II) cervical cancer was present in 244/288 (84.7%) women, while 44 (15.3%) presented with advanced disease (stage III/IV). The chest radiograph of 1 woman – with advanced pre-radiograph stage (IVA) disease – showed findings consistent with pulmonary metastases. Radiographs of 7 other women – 4 early, 3 advanced stage disease – were suspicious for pulmonary metastases which was confirmed by additional imaging in only 1 woman (with pre-radiograph advanced stage (IIIB) disease) and excluded in 6 cases, including all women with early stage disease. In none of the 288 women were thoracic skeletal metastases identified on imaging or during 6 months follow up. Radiography was unremarkable in 76.4% of the study population, and showed findings unrelated to the cervical carcinoma in 21.2%. Conclusion Routine chest radiography was of no value for any of the early stage cervical cancer patients presenting at our tertiary center over a period of 7.7 years. PMID:26135733

    Although blind people heavily depend on working memory to manage daily life without visual information, it is not clear yet whether their working memory processing involves functional reorganization of the memory-related cortical network. To explore functional reorganization of the cortical network that supports various types of working memory processes in the early blind, we investigated activation differences between 2-back tasks and 0-back tasks using fMRI in 10 congenitally blind subjects and 10 sighted subjects. We used three types of stimulus sequences: words for a verbal task, pitches for a non-verbal task, and sound locations for a spatial task. When compared to the sighted, the blind showed additional activations in the occipital lobe for all types of stimulus sequences for working memory and more significant deactivation in the posterior cingulate cortex of the default mode network. The blind had increased effective connectivity from the default mode network to the left parieto-frontal network and from the occipital cortex to the right parieto-frontal network during the 2-back tasks than the 0-back tasks. These findings suggest not only cortical plasticity of the occipital cortex but also reorganization of the cortical network for the executive control of working memory.

    The aim of the study was to investigate how starting to use dialectical behavioural therapy (DBT) in the work with young self-harming women showing symptoms of borderline personality disorder affected the psychiatric professionals (n = 22) experience of occupational stress and levels of professional burnout. The study was carried out in relation to an 18-month clinical psychiatric development project, and used a mix of quantitative and qualitative research methods [a burnout inventory, the Maslach burnout inventory-General Survey (MBI-GS), free format questionnaires and group interviews]. The result confirms previous reports that psychiatric health professionals experience treatment of self-harming patients as very stressful. DBT was seen as stressful in terms of learning demands, but decreased the experience of stress in the actual treatment of the patients. The teamwork and supervision were felt to be supportive, as was one particular facet of DBT, namely mindfulness training which some therapists felt also improved their handling of other work stressors not related to DBT. The inventory for professional burnout, the MBI-GS, showed no significant changes over the 18-month period, although there was a tendency for increased burnout levels at the 6-month assessment, which had returned to baseline levels at 18 months.

    Behavioural and neuroimaging studies provide evidence for a possible "sensitive" period in childhood development during which musical training results in long-lasting changes in brain structure and auditory and motor performance. Previous work from our laboratory has shown that adult musicians who begin training before the age of 7 (early-trained; ET) perform better on a visuomotor task than those who begin after the age of 7 (late-trained; LT), even when matched on total years of musical training and experience. Two questions were raised regarding the findings from this experiment. First, would this group performance difference be observed using a more familiar, musically relevant task such as auditory rhythms? Second, would cognitive abilities mediate this difference in task performance? To address these questions, ET and LT musicians, matched on years of musical training, hours of current practice and experience, were tested on an auditory rhythm synchronization task. The task consisted of six woodblock rhythms of varying levels of metrical complexity. In addition, participants were tested on cognitive subtests measuring vocabulary, working memory and pattern recognition. The two groups of musicians differed in their performance of the rhythm task, such that the ET musicians were better at reproducing the temporal structure of the rhythms. There were no group differences on the cognitive measures. Interestingly, across both groups, individual task performance correlated with auditory working memory abilities and years of formal training. These results support the idea of a sensitive period during the early years of childhood for developing sensorimotor synchronization abilities via musical training.

    To examine the associations of mental health functioning (SF-36) and work and family related psychosocial factors with intentions to retire early. Cross sectional survey data (n = 5037) from the Helsinki Health Study occupational cohort in 2001 and 2002 were used. Intentions to retire early were inquired with a question: "Have you considered retiring before normal retirement age?" Mental health functioning was measured by the Short Form 36 (SF-36) mental component summary (MCS). Work and family related psychosocial factors included job demands and job control, procedural and relational justice, conflicts between work and family, and social network size. Multinomial regression models were used to analyse the data. Poor mental health functioning, unfavourable psychosocial working conditions, and conflicts between work and family were individually related to intentions to retire early. After adjustments for all work and family related factors the odds ratio for low mental health functioning was halved (from OR = 6.05 to 3.67), but nevertheless the association between poor mental health functioning and strong intentions to retire early remained strong. These findings highlight not only the importance of low mental health and unfavourable working conditions but also the simultaneous impact of conflicts between work and family to employees' intentions to retire early.

    Lysophosphatidic acid (LPA) induces a variety of cellular signaling pathways through the activation of its cognate G protein-coupled receptors. To investigate early LPA responses and assess the contribution of epidermal growth factor (EGF) receptor transactivation in LPA signaling, we performed phosphoproteomics analyses of both total cell lysate and protein kinase-enriched fractions as complementary strategies to monitor phosphorylation changes in A498 kidney carcinoma cells. Our integrated work flow enabled the identification and quantification of more than 5,300 phosphorylation sites of which 224 were consistently regulated by LPA. In addition to induced phosphorylation events, we also obtained evidence for early dephosphorylation reactions due to rapid phosphatase regulation upon LPA treatment. Phosphorylation changes induced by direct heparin-binding EGF-like growth factor-mediated EGF receptor activation were typically weaker and only detected on a subset of LPA-regulated sites, indicating signal integration among EGF receptor transactivation and other LPA-triggered pathways. Our results reveal rapid phosphoregulation of many proteins not yet implicated in G protein-coupled receptor signaling and point to various additional mechanisms by which LPA might regulate cell survival and migration as well as gene transcription on the molecular level. Moreover, our phosphoproteomics analysis of both total lysate and kinase-enriched fractions provided highly complementary parts of the LPA-regulated signaling network and thus represents a useful and generic strategy toward comprehensive signaling studies on a system-wide level.

    Prenatal and childhood exposure to polybrominated diphenyl ether (PBDE) flame retardants has been inversely associated with cognitive performance, however, few studies have measured PBDE concentrations in samples collected during both prenatal and postnatal periods. We examined prenatal (cord) and childhood (ages 2, 3, 5, 7 and 9 years) plasma PBDE concentrations in relation to memory outcomes assessed between the ages of 9 and 14 years. The study sample includes a subset (n = 212) of the African American and Dominican children enrolled in the Columbia Center for Children's Environmental Health Mothers and Newborns birth cohort. We used multivariable linear regression to examine associations between continuous log 10 -transformed PBDE concentrations and performance on tests of visual, verbal and working memory in age-stratified models. We additionally used latent class growth analysis to estimate trajectories of exposure across early life, which we analyzed as a categorical variable in relation to memory outcomes. We examined interactions between PBDE exposure and sex using cross-product terms. Associations between prenatal exposure and working memory significantly varied by sex (p-interaction = 0.02), with inverse relations observed only among girls (i.e. β BDE-47  = -7.55, 95% CI: -13.84, -1.24). Children with sustained high concentrations of BDEs-47, 99 or 100 across childhood scored approximately 5-8 standard score points lower on tests of visual memory. Children with PBDE plasma concentrations that peaked during toddler years performed better on verbal domains, however, these associations were not statistically significant. Exposure to PBDEs during both prenatal and postnatal periods may disrupt memory domains in early adolescence. These findings contribute to a substantial body of evidence supporting the developmental neurotoxicity of PBDEs and underscore the need to reduce exposure among pregnant women and children.

    Professor Ebashi's epic work on the biochemistry of the regulation of muscle contraction began in the early 1950's, during the same period that work on the molecular basis of force production in muscle was also beginning. The latter work started in two MRC Research Units in the UK, and was continued jointly by the two workers from those Units who had, independently, gone to MIT to learn the new techniques of electron microscopy and to apply them to muscle. In a somewhat similar fashion, Professor Ebashi also spent one or two years in the USA, continuing his work on themore » role of calcium in muscle regulation in Lippman's laboratory, before returning to Japan to achieve the great breakthroughs in this work during the 1960's. Hanson and Huxley, after putting forward the overlapping actin and myosin filament arrays model for the striated muscle sarcomere, and subsequently the sliding filament model of muscle contraction (simultaneously with A.F Huxley and R. Niedergerke), returned to the UK to pursue detailed structural studies in separate Research Units, in a mixture of consultation, collaboration, and competition, during the later 1950's and throughout the 1960's. However, the path to enlightenment described here in some detail was somewhat more tortuous than the standard literature perhaps reveals. Nevertheless, by the time of the Cold Spring Harbor Symposium on Muscle Contraction in 1972, the two lines of enquiry on regulation itself, and on the tilting cross-bridge model of force production, had arrived at a good deal of common ground, and indeed the identification of troponin and its periodic distribution along the actin filaments had helped resolve a long-standing puzzle in the interpretation of the low angle X-ray diagram. Since then, an enormous amount of remarkable new work has been necessary to establish troponin regulation and the tilting cross-bridge mechanism in molecular detail, but the work in the 1950's and 1960's has provided a firm and accurate

    Chromatin structure is believed to exert a strong effect on replication origin function. We have studied the replication of the chicken β-globin locus, whose chromatin structure has been extensively characterized. This locus is delimited by hypersensitive sites (HSs) that mark the position of insulator elements. A stretch of condensed chromatin and another HS separate the β-globin domain from an adjacent folate receptor (FR) gene. We demonstrate here that in erythroid cells that express the FR but not the globin genes, replication initiates at four sites within the β-globin domain, one at the 5′ HS4 insulator and the other three near the ρ- and βA-globin genes. Three origins consist of G+C-rich sequences enriched in CpG dinucleotides. The fourth origin is A+T rich. Together with previous work, these data reveal that the insulator origin has unmethylated CpGs, hyperacetylated histones H3 and H4, and lysine 4-methylated histone H3. In contrast, opposite modifications are observed at the other G+C-rich origins. We also show that the whole region, including the stretch of condensed chromatin, replicates early in S phase in these cells. Therefore, different early-firing origins within the same locus may have opposite patterns of epigenetic modifications. The role of insulator elements in DNA replication is discussed. PMID:12724412

    Carpal tunnel syndrome is common at the largest lamb processing plant in the world, especially in new lamb boners. The purpose of this study was to establish the incidence and whether expeditious return to work following open carpal tunnel decompression was possible. Two hundred patients with a neurophysiologically confirmed diagnosis underwent surgery between 2002 and 2006. One hundred and eighty-seven patients were assessed retrospectively and 13 prospectively. The incidence in new lamb boners was 10% in their first season. On average, workers commenced rehabilitation at 11 days post-operatively and full duties at 29 days post-operatively with minimal further time off taken. Ninety percent returned to their previous role. By 8 weeks in the prospective group visual analogue pain scores had improved from 8.75 to 2.0 (P<0.01) and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores had improved from 140 points to 68 (P<0.01). Grip/pinch testing, static two-point discrimination scores and complication rates were comparable with previous studies. This study provides good evidence that coordinated, early rehabilitation and return to work is effective in a high-demand population.

    The purpose of this study was to develop and evaluate a model of labor force participation among a group of older women in the United States. A comprehensive measure of women's combined work and family experiences across the adult life course was created. Employing data from the 1984 Survey of Income and Program Participation, we applied multinomial logistic regression techniques to examine the association between work-family experiences and later life labor supply. Our findings generally support an attachment hypothesis, showing that women who were the most work-oriented throughout the life course were more likely than women who experienced family-related spells of nonlabor-market activity to participate in the labor force, either full-time or part-time, later in life.

    Viral variants that predominate during early infection may exhibit constrained diversity compared with those found during chronic infection and could contain amino acid signature patterns that may enhance transmission, establish productive infection, and influence early events that modulate the infection course. We compared amino acid distributions in 17 patients recently infected with HIV-1C with patients with chronic infection. We found significantly lower entropy in inferred transmitted/founder (t/f) compared with chronic viruses and identified signature patterns in Vif and Vpr from inferred t/f viruses. We investigated sequence evolution longitudinally up to 500 days postseroconversion and compared the impact of selected substitutions on predicted human leukocyte antigen (HLA) binding affinities of published and predicted cytotoxic T-lymphocyte epitopes. Polymorphisms in Vif and Vpr during early infection occurred more frequently at epitope-HLA anchor residues and significantly decreased predicted epitope-HLA binding. Transmission-associated sequence signatures may have implications for novel strategies to prevent HIV-1 transmission.

    The molecular mechanisms responsible for the pathophysiological traits of type 2 diabetes are incompletely understood. Here we have performed transcriptomic analysis in skeletal muscle, and plasma metabolomics from subjects with classical and early-onset forms of type 2 diabetes (T2D). Focused studies were also performed in tissues from ob/ob and db/db mice. We document that T2D, both early and late onset, are characterized by reduced muscle expression of genes involved in branched-chain amino acids (BCAA) metabolism. Weighted Co-expression Networks Analysis provided support to idea that the BCAA genes are relevant in the pathophysiology of type 2 diabetes, and that mitochondrial BCAA management is impaired in skeletal muscle from T2D patients. In diabetic mice model we detected alterations in skeletal muscle proteins involved in BCAA metabolism but not in obese mice. Metabolomic analysis revealed increased levels of branched-chain keto acids (BCKA), and BCAA in plasma of T2D patients, which may result from the disruption of muscle BCAA management. Our data support the view that inhibition of genes involved in BCAA handling in skeletal muscle takes place as part of the pathophysiology of type 2 diabetes, and this occurs both in early-onset and in classical type 2 diabetes.

    Carling, Christopher; Bloomfield, Jonathan

    2010-01-01

    The aim of this study was to examine the effects of an early dismissal (after 5-min play) on work-rate in a professional soccer match. A computerised player tracking system was used to assess the work-rates of seven players who completed the match on a team with 10 players. A minute-by-minute analysis of the remaining 91min following the dismissal was performed for the total distance covered, the distance covered in five categories of movement intensity and the recovery time between high-intensity efforts for each player. The data were calculated for each half and for three equal intervals within each half and profiled against normative data for the same players obtained from the analysis of 15 games in the same season. Following the dismissal, the players covered a greater total distance than normal (p<0.025), particularly in moderate-intensity activities (p<0.01) and had shorter recovery times between high-intensity efforts (p<0.025). In contrast, there was a significant reduction between game halves for total distance covered at both the highest (p<0.025) and lowest running intensities (p<0.01). However, there were no differences in high-intensity activities across the three intervals in the second-half. These findings suggest that in 11 vs. 11, players may not always utilise their full physical potential as this match illustrated an increase in overall work-rate when reduced to 10 players. However, as a team with 10 players is likely to incur higher levels of fatigue, tactical alterations may be necessary and/or players may adopt a pacing strategy to endure the remainder of the match.

    1998-01-01

    The aim of the study was to identify conditions associated with occupational exclusion from home-caring. In a group of 346 home-care workers who responded to a questionnaire, there were 18 newly-retired carers on early-retirement/disability pensions, and 28 carers who had just taken regular retirement. A discriminant analysis was conducted to identify work conditions that differentiated the two groups. The results show that a combination of variables--functional impairment (pain when doing physical work), psychosomatic complaints, and nature of relationship with/attitude to clients--significantly differentiated the two groups. When the discriminant coefficients were applied to other groups--older full-time and part-time employees (n = 224), carers who had undergone job transfers, and carers on long-term sick leave--the order of groups by discriminant-point score was largely as expected. The results are discussed in relation to dilemmas, psychological demands and organizational circumstances prevailing in home-care work.

    A study of contemporary handbooks for justices of the peace, sworn depositions, and other judicial records shows that in early Stuart England people were relatively tolerant of homosexuality. Sodomy was a minor felony, but more than homosexual activity was required to prosecute an offender. Persons accused of religious heresy, political offenses, or violating social-class distinctions also might be charged with sodomy, as illustrated by the cases of Lord Audley, Earl of Castlehaven and John Atherton, Bishop of Waterford and Lismore. Although the Puritans expanded the list of sexual acts proscribed as vices, even they did not react to it with the extreme horror characteristic of the Victorian era and the present day.

    Previous research has documented socioeconomic-related disparities in children's working memory; however, the putative proximal caregiving mechanisms that underlie these effects are less known. The present study sought to examine whether the effects of early family socioeconomic status on children's working memory were mediated through experiences of caregiving, specifically maternal harsh discipline and responsiveness. Utilizing a psychobiological framework of parenting, the present study also tested whether maternal working memory moderated the initial paths between the family socioeconomic context and maternal harsh discipline and responsiveness in the mediation model. The sample included 185 socioeconomically diverse mother-child dyads assessed when children were 3.5 and 5 years old. Results demonstrated that maternal harsh discipline was a unique mediator of the relation between early experiences of family socioeconomic adversity and lower working memory outcomes in children. Individual differences in maternal working memory emerged as a potent individual difference factor that specifically moderated the mediating influence of harsh discipline within low socioeconomic contexts. The findings have implications for early risk processes underlying deficits in child working memory outcomes and potential targets for parent-child interventions.

    Objective This study examines the impact of organizational change and psychosocial work environment on non-disability early retirement among senior public service employees. Methods In January and February 2011, Danish senior public service employees aged 58-64 years (N=3254) from the Capital Region of Denmark responded to a survey assessing psychosocial work environment (ie, social capital, organizational justice, and quality of management). Work-unit organizational changes (ie, change of management, merging, demerging, and relocation) were recorded from January 2009 to March 2011. Weekly data on non-disability early retirement transfer were obtained from the DREAM register database, which holds weekly information about all public benefit payments in Denmark. Hazard ratios (HR) for early retirement following employees' 60 th birthday were estimated with Cox regression adjusted for age, gender, and socioeconomic status. Results Exposure to change of management [HR 1.37, 95% confidence interval (95% CI) 1.13-1.66], mergers (HR 1.23, 95% CI 1.02-1.48), and relocation of work unit (HR 1.24, 95% CI 1.01-1.54) increased rate of non-disability early retirement, while demerging of work unit did not (HR 1.03, 95% CI 0.79-1.33). Work units with lower levels of social capital (HR 1.22, 95% CI 1.05-1.41), organizational justice, (HR 1.18, 95% CI 1.04-1.32), and quality of management (HR 1.14, 95% CI 1.02-1.25) increased rate of early retirement. Conclusion Organizational change and poor psychosocial work environment contribute to non-disability early retirement among senior public service employees, measured at work-unit level.

    Personal resources are identified as important for the ability to return to work (RTW) for patients with ischaemic heart disease (IHD) or heart failure (HF) undergoing cardiac rehabilitation (CR). The patient education 'Learning and Coping' (LC) addresses personal resources through a pedagogical approach. This trial aimed to assess effect of adding LC strategies in CR compared to standard CR measured on RTW status at one-year follow-up after CR. In an open parallel randomised controlled trial, patients with IHD or HF were block-randomised in a 1:1 ratio to the LC arm (LC plus CR) or the control arm (CR alone) across three Danish hospital units. Eligible patients were aged 18 to ≤60 and had not left the labour market. The intervention was developed from an inductive pedagogical approach consisting of individual interviews and group based teaching by health professionals with experienced patients as co-educators. The control arm consisted of deductive teaching (standard CR). RTW status was derived from the Danish Register for Evaluation of Marginalisation (DREAM). Blinding was not possible. The effect was evaluated by logistic regression analysis and reported as crude and adjusted odds ratios (OR) with 95% confidence interval (CI). The population for the present analysis was N = 244 (LC arm: n = 119 versus control arm: n = 125). No difference in RTW status was found at one year across arms (LC arm: 64.7% versus control arm: 68.8%, adjusted odds ratio OR: 0.76, 95% CI: 0.43-1.31). Addition of LC strategies in CR showed no improvement in RTW at one year follow-up. www.clinicaltrials.gov identifier NCT01668394. First Posted: August 20, 2012.

  10. Showing Value in Newborn Screening: Challenges in Quantifying the Effectiveness and Cost-Effectiveness of Early Detection of Phenylketonuria and Cystic Fibrosis

    Decision makers sometimes request information on the cost savings, cost-effectiveness, or cost-benefit of public health programs. In practice, quantifying the health and economic benefits of population-level screening programs such as newborn screening (NBS) is challenging. It requires that one specify the frequencies of health outcomes and events, such as hospitalizations, for a cohort of children with a given condition under two different scenarios—with or without NBS. Such analyses also assume that everything else, including treatments, is the same between groups. Lack of comparable data for representative screened and unscreened cohorts that are exposed to the same treatments following diagnosis can result in either under- or over-statement of differences. Accordingly, the benefits of early detection may be understated or overstated. This paper illustrates these common problems through a review of past economic evaluations of screening for two historically significant conditions, phenylketonuria and cystic fibrosis. In both examples qualitative judgments about the value of prompt identification and early treatment to an affected child were more influential than specific numerical estimates of lives or costs saved.

    Postnatal depression is a major public health problem with clearly established adverse effects in child outcomes. This study examines the 4-year outcomes of a screening and early intervention programme, in relation to improvement in symptoms, functioning and health quality of life. Women were prospectively recruited up to 6 months postdelivery, using the Edinburgh Postnatal Depression Scale (EPDS) as a screening tool. High-scorers (EPDS >13), were offered psychiatric consultation, and those with borderline scores (EPDS 10-12) were provided counselling, and offered follow-up phone counselling by the assigned case manager. Outcome measures were obtained at baseline, and at 6 months or discharge if earlier, for levels of symptoms, functioning, and health quality of life. From 2008 to 2012, 5245 women were screened, with 307 (5.9%) women with EPDS >13 receiving intervention. Of these, 70.0% had depression, 4.6% anxiety and 3.4% psychosis. In the depression subgroup, the net change was improvement of 93.4% EPDS symptom scores, 92.2% Global Assessment of Functioning (GAF) scores, and 88.3% visual analogue scale (EQ VAS) health quality of life scores. Outcome scores across diagnostic categories demonstrated median changes of 10 points on EPDS, 20 points on GAF, and 25 points on EQ VAS, reflecting 73.9%, 36.4% and 41.7% change from baseline scores. Women with psychosis showed the biggest (80.0%) relative change in GAF functioning scores from baseline to discharge but had the lowest median change in EPDS symptom scores. A screening and intervention programme rightly-sited within an obstetric setting can improve clinical outcomes because of early detection and intervention.

    The major histocompatibility complex (MHC) plays a crucial role in the adaptive immune system and has been extensively studied across vertebrate taxa. Although the function of MHC genes appears to be conserved across taxa, there is great variation in the number and organisation of these genes. Among avian species, for instance, there are notable differences in MHC structure between passerine and non-passerine lineages: passerines typically have a high number of highly polymorphic MHC paralogs whereas non-passerines have fewer loci and lower levels of polymorphism. Although the occurrence of highly polymorphic MHC paralogs in passerines is well documented, their evolutionary origins are relatively unexplored. The majority of studies have focussed on the more derived passerine lineages and there is very little empirical information on the diversity of the MHC in basal passerine lineages. We undertook a study of MHC diversity and evolutionary relationships across seven species from four families (Climacteridae, Maluridae, Pardalotidae, Meliphagidae) that comprise a prominent component of the basal passerine lineages. We aimed to determine if highly polymorphic MHC paralogs have an early evolutionary origin within passerines or are a more derived feature of the infraorder Passerida. We identified 177 alleles of the MHC class II β exon 2 in seven basal passerine species, with variation in numbers of alleles across individuals and species. Overall, we found evidence of multiple gene loci, pseudoalleles, trans-species polymorphism and high allelic diversity in these basal lineages. Phylogenetic reconstruction of avian lineages based on MHC class II β exon 2 sequences strongly supported the monophyletic grouping of basal and derived passerine species. Our study provides evidence of a large number of highly polymorphic MHC paralogs in seven basal passerine species, with strong similarities to the MHC described in more derived passerine lineages rather than the simpler MHC

    This study was conducted to investigate the relationship between perceived work-related stress and preclinical atherosclerosis. A total of 100 managers and 50 office workers aged 35-65 participated in a questionnaire study. Individual, family and work-related stress risk factors and coping were evaluated in all the studied individuals. Serum levels of biochemical (total cholesterol, LDL, HDL, TG, glucose) and serological risk factors of atherosclerosis (anticardiolipin, anti-beta(2) GPI, anti-oxLDL, anti-HSP and anti-hsCRP antibodies) were evaluated. A computer analysis of B-mode ultrasound images was used to assess carotid artery intima-media thickness (IMT) and atherosclerotic plaque in carotid arteries. Statistical analysis was conducted with SPSS v. 11.5. The studied individuals showed average ranges of both the global stress level and of coping results. In 71% no changes were found in the ultrasound image and in 29% of individuals (43) the presence of plaque was shown. The mean value of the IMT measure was 0.0618 +/- 0.013 mm. IMT and plaque correlated negatively with the level of global work-related stress (r = -0.26; P < 0.01; and r = -0.28; P < 0.01; respectively). No correlation was found either between work-related stress and coping, or between coping and IMT (P > 0.05), or between work-related stress and healthy lifestyle (no smoking, no excessive use of alcohol, high physical activity), or between healthy lifestyle and IMT (P > 0.05). Positive correlation between IMT and LDL and smoking did not result from higher stress reaction in the studied individuals. The explanation of the negative correlation between perceived work-related stress and preclinical atherosclerosis was not confirmed either by the subjects under high stress undertaking healthy protective activities or by their escaping into unhealthy behaviour. The most probable interpretation of the results is that in individuals with a low level of perceived work-related stress, somatization of

    Depression symptom severity, the most commonly studied outcome in antidepressant treatment trials, accounts for only a small portion of burden related to major depression. While lost work productivity is the biggest contributor to depression's economic burden, few studies have systematically evaluated the independent effect of treatment on work productivity and the relationship between changes in work productivity and longer-term clinical course. Work productivity was measured repeatedly by the Work Productivity and Activity Impairment self-report questionnaire in 331 employed participants with major depression enrolled in the Combining Medications to Enhance Depression Outcomes trial. Trajectories of change in work productivity during the first 6 weeks of treatment were identified and used to predict remission at 3 and 7 months. Participants reported reduced absence from work and increased work productivity with antidepressant treatment even after controlling for changes in depression severity. Three distinct trajectories of changes in work productivity were identified: 1) robust early improvement (24%), 2) minimal change (49%), and 3) high-impairment slight reduction (27%). Compared with other participants, those with robust improvement had 3-5 times higher remission rates at 3 months and 2-5 times higher remission rates at 7 months, even after controlling for select baseline variables and remission status at week 6. In this secondary analysis, self-reported work productivity improved in depressed patients with antidepressant treatment even after accounting for depressive symptom reduction. Early improvement in work productivity is associated with much higher remission rates after 3 and 7 months of treatment.

    We determined the prevalence of work disability in early rheumatoid arthritis (ERA) and undifferentiated early inflammatory arthritis (EIA) patients at first enrollment into the Canadian Early Arthritis Cohort (CATCH) who met the 2010 ACR criteria versus those not meeting criteria, to determine the impact of meeting new criteria on work disability status. Data at first visit into the cohort were analyzed. Descriptive statistics and logistic regression analyses were performed to investigate the association of other variables in our database with work disability. 1,487 patients were enrolled in the CATCH study, a multi-site observational, prospective cohort of patients with EIA. 934 patients were excluded (505 based on missing criteria for ACR 2010 classification, as anti-CCP was absent, and 429 were not working for other reasons). Of the 553 patients included, 71 % were female with mean disease duration of 6.4 months. 524 (94.8 %) were employed while 29 (5.2 %) reported work disability at first visit. There were no differences between those meeting 2010 ACR criteria versus those who did not. Baseline characteristics associated with work disability were male gender, age, education, income, HAQ, and positive RF status. The mean HAQ score in work disabled patients was 1.4 versus 0.9 in those who were working (p < 0.001). Disease activity score (DAS28) was not associated with work disability (p = 0.069), nor was tender joint count, swollen joint count, anti-CCP, patient global assessment, or SF-12v2. In the regression model, work disability was associated with lower income levels (p = 0.01) and worse HAQ scores (OR 2.33; p = 0.001), but not significantly associated with male gender (p = 0.08), older age (>50 years; p = 0.3), lower education (p = 0.3) or RF positivity (p = 0.6). We found rates of work disability to be low at entry into this EIA cohort compared to previous studies. There may be potential for intervention in ERA to prevent the development of work

  16. Horizontal slip along Alleghanian joints of the Appalachian plateau: evidence showing that mild penetrative strain does little to change the pristine appearance of early joints

    Some Alleghanian joints in black shales of the Geneseo and Middlesex Formations of the Catskill Delta complex, Finger Lakes district, New York, slipped horizontally up to 8 cm. Horizontal slip is measured by the offset of ENE-striking joints. Alleghanian joints striking 330-350° display a right-lateral slip with an average value of 1.9 cm, while joints striking 004-010° slip in the left-lateral sense with an average value of 1.3 cm. The maximum horizontal stress (SH) driving this slip falls between 350° and 004°, the orientation of local Alleghanian layer-parallel shortening as indicated by both disjunctive and pencil cleavage. By commonality of orientation, we infer that slip on Alleghanian joints is driven contemporaneously with layer-parallel shortening. If so, the offset ENE-striking joints predate the Alleghanian stress field. These observations mean that both pre-Alleghanian and early Alleghanian joints persist through a period of penetrative strain.

    To estimate the development and potential disproportional distribution of longterm productivity costs (PC) and their determinants leading to work absenteeism and permanent work disability in working-aged patients with early rheumatoid arthritis (RA). A cohort of subjects with early RA was created by identifying the new cases of RA from the national drug reimbursement register that had been granted a special reimbursement for their antirheumatic medications for RA from 2000-2007. The dataset was enriched by cross-linking with other national registries detailing work absenteeism days and permanent disability pensions. In the base case, the human capital approach was applied to estimate PC based on subjects' annual number of absenteeism days and incomes. Hurdle regression analysis was applied to study the determinants of PC. Among the 7831 subjects with early RA, the mean (bootstrapped 95% CI) annual PC per person-observation year was €4800 (4547-5070). The annual PC declined after the first year of RA diagnosis, but increased significantly in subsequent years. In addition, the PC was heavily disproportionally concentrated in a small fraction of patients with RA, because only around 20% of patients accounted for the majority of total annual PC. The initiation of active drug treatment during the first 3 months after RA diagnosis significantly reduced the cumulative PC when compared with no drug treatment. The longterm PC increased significantly in parallel with years elapsing after RA diagnosis. Further, the majority of these PC are incurred by a small proportion of patients.

    To examine correlates of early initiation into sex work in two Mexico-U.S. border cities. Female sex workers (FSWs) >/=18 years without known HIV infection living in Tijuana and Ciudad Juarez who had recent unprotected sex with clients underwent baseline interviews. Correlates of initiation into sex work before age 18 were identified with logistic regression. Of 920 FSWs interviewed in Tijuana (N=474) and Ciudad Juarez (N=446), 9.8% (N=90) were early initiators (<18 years) into sex work. Median age of entry into sex work was 26 years (range: 6-58). After adjusting for age, compared to older initiators, early initiators were more likely to use inhalants (21.1% vs. 9.6%, p=.002), initiate sex work to pay for alcohol (36.7% vs. 18.4%, p < .001), report abuse as a child (42.2% vs. 18.7%, p<.0001), and they were less likely to be migrants (47.8% vs. 62.3%, p=.02). Factors independently associated with early initiation included inhalant use (adjOR=2.39), initiating sex work to pay for alcohol (adjOR=1.88) and history of child abuse (adjOR=2.92). Factors associated with later initiation included less education (adjOR=0.43 per 5-year increase), migration (adjOR=0.47), and initiating sex work for better pay (adjOR=0.44) or to support children (adjOR=0.03). Different pathways for entering sex work are apparent among younger versus older females in the Mexico-U.S. border region. Among girls, interventions are needed to prevent inhalant use and child abuse and to offer coping skills; among older initiators, income-generating strategies, childcare, and services for migrants may help to delay or prevent entry into sex work.

    ABSTRACT Huntington disease (HD) is a brain disorder characterized by the late onset of motor and cognitive symptoms, even though the neurons in the brain begin to suffer dysfunction and degeneration long before symptoms appear. There is currently no cure. Several molecular and developmental effects of HD have been identified using neural stem cells (NSCs) and differentiated cells, such as neurons and astrocytes. Still, little is known regarding the molecular pathogenesis of HD in pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). Therefore, we examined putative signaling pathways and processes involved in HD pathogenesis in pluripotent cells. We tested naïve mouse HD YAC128 iPSCs and two types of human HD iPSC that were generated from HD and juvenile-HD patients. Surprisingly, we found that a number of changes affecting cellular processes in HD were also present in undifferentiated pluripotent HD iPSCs, including the dysregulation of the MAPK and Wnt signaling pathways and the dysregulation of the expression of genes related to oxidative stress, such as Sod1. Interestingly, a common protein interactor of the huntingtin protein and the proteins in the above pathways is p53, and the expression of p53 was dysregulated in HD YAC128 iPSCs and human HD iPSCs. In summary, our findings demonstrate that multiple molecular pathways that are characteristically dysregulated in HD are already altered in undifferentiated pluripotent cells and that the pathogenesis of HD might begin during the early stages of life.

    This paper examines four primary methods of working across disciplines during R&D and early design of large-scale complex engineered systems such as aerospace systems. A conceptualized framework, called the Combining System Elements framework, is presented to delineate several aspects of cross-discipline and system integration practice. The framework is derived from a theoretical and empirical analysis of current work practices in actual operational settings and is informed by theories from organization science and engineering. The explanatory framework may be used by teams to clarify assumptions and associated work practices, which may reduce ambiguity in understanding diverse approaches to early systems research, development and design. The framework also highlights that very different engineering results may be obtained depending on work practices, even when the goals for the engineered system are the same.

    We explored direct and indirect influences of physical work environment on job satisfaction in a nationally representative sample of 1,141 early-career registered nurses. In the fully specified model, physical work environment had a non-significant direct effect on job satisfaction. The path analysis used to test multiple indirect effects showed that physical work environment had a positive indirect effect (p < .05) on job satisfaction through ten variables: negative affectivity, variety, workgroup cohesion, nurse-physician relations, quantitative workload, organizational constraints, distributive justice, promotional opportunity, local and non-local job opportunities. The findings make important contributions to the understanding of the relationship between physical work environment and job satisfaction. The results can inform health care leaders' insight about how physical work environment influences nurses' job satisfaction. © 2014 Wiley Periodicals, Inc.

    Identifying differences and similarities between cutaneous lymphocyte antigen (CLA)(+) polarized T-cell subsets in children versus adults with atopic dermatitis (AD) is critical for directing new treatments toward children. We sought to compare activation markers and frequencies of skin-homing (CLA(+)) versus systemic (CLA(-)) "polar" CD4 and CD8 T-cell subsets in patients with early pediatric AD, adults with AD, and control subjects. Flow cytometry was used to measure CD69/inducible costimulator/HLA-DR frequency in memory cell subsets, as well as IFN-γ, IL-13, IL-9, IL-17, and IL-22 cytokines, defining TH1/cytotoxic T (TC) 1, TH2/TC2, TH9/TC9, TH17/TC17, and TH22/TC22 populations in CD4 and CD8 cells, respectively. We compared peripheral blood from 19 children less than 5 years old and 42 adults with well-characterized moderate-to-severe AD, as well as age-matched control subjects (17 children and 25 adults). Selective inducible costimulator activation (P < .001) was seen in children. CLA(+) TH2 T cells were markedly expanded in both children and adults with AD compared with those in control subjects, but decreases in CLA(+) TH1 T-cell numbers were greater in children with AD (17% vs 7.4%, P = .007). Unlike in adults, no imbalances were detected in CLA(-) T cells from pediatric patients with AD nor were there altered frequencies of TH22 T cells within the CLA(+) or CLA(-) compartments. Adults with AD had increased frequencies of IL-22-producing CD4 and CD8 T cells within the skin-homing population, compared with controls (9.5% vs 4.5% and 8.6% vs 2.4%, respectively; P < .001), as well as increased HLA-DR activation (P < .01). These data suggest that TH2 activation within skin-homing T cells might drive AD in children and that reduced counterregulation by TH1 T cells might contribute to excess TH2 activation. TH22 "spreading" of AD is not seen in young children and might be influenced by immune development, disease chronicity, or recurrent skin infections

  14. H3S10ph broadly marks early-replicating domains in interphase ESCs and shows reciprocal antagonism with H3K9me2.

    Phosphorylation of histone H3 at serine 10 (H3S10ph) by Aurora kinases plays an important role in mitosis; however, H3S10ph also marks regulatory regions of inducible genes in interphase mammalian cells, implicating mitosis-independent functions. Using the fluorescent ubiquitin-mediated cell cycle indicator (FUCCI), we found that 30% of the genome in interphase mouse embryonic stem cells (ESCs) is marked with H3S10ph. H3S10ph broadly demarcates gene-rich regions in G1 and is positively correlated with domains of early DNA replication timing (RT) but negatively correlated with H3K9me2 and lamin-associated domains (LADs). Consistent with mitosis-independent kinase activity, this pattern was preserved in ESCs treated with Hesperadin, a potent inhibitor of Aurora B/C kinases. Disruption of H3S10ph by expression of nonphosphorylatable H3.3S10A results in ectopic spreading of H3K9me2 into adjacent euchromatic regions, mimicking the phenotype observed in Drosophila JIL-1 kinase mutants . Conversely, interphase H3S10ph domains expand in Ehmt1 (also known as Glp ) null ESCs, revealing that H3S10ph deposition is restricted by H3K9me2. Strikingly, spreading of H3S10ph at RT transition regions (TTRs) is accompanied by aberrant transcription initiation of genes co-oriented with the replication fork in Ehmt1 -/- and Ehmt2 -/- ESCs, indicating that establishment of repressive chromatin on the leading strand following DNA synthesis may depend upon these lysine methyltransferases. H3S10ph is also anti-correlated with H3K9me2 in interphase murine embryonic fibroblasts (MEFs) and is restricted to intragenic regions of actively transcribing genes by EHMT2. Taken together, these observations reveal that H3S10ph may play a general role in restricting the spreading of repressive chromatin in interphase mammalian cells. © 2018 Chen et al.; Published by Cold Spring Harbor Laboratory Press.

    The purpose of this study was to investigate the ability of patients to return to their preoperative work level and to identify functional prognostic factors in a group of Workers' Compensation (WC) patients after arthroscopic repair of full-thickness rotator cuff tears at a minimum follow-up of 1 year. Seventy-eight consecutive WC patients underwent arthroscopic rotator cuff repair (ARCR) and were retrospectively reviewed. Potential predictors of occupational outcomes were recorded. The primary outcomes included work level at the time of discharge, time to maximum medical improvement (MMI), and failures requiring revision rotator cuff repair. Secondary outcomes including physical examination and subjective scoring scales were also recorded. Overall, 88.5% of patients (n = 69) returned to their preoperative level of work at a mean time to MMI of 7.6 +/- 2.6 months. Of the WC patients, 55 (70.5%) were followed up for purposes of assessing shoulder function, with a mean follow-up of 33.6 +/- 13.9 months. The mean American Shoulder and Elbow Surgeons score at this time was 82.3 +/- 20.9, and the mean score on a visual analog scale was 1.7 +/- 2.3. An association was found between patients who underwent ARCR with open biceps tenodesis and delay in MMI (P = .01). WC patients undergoing ARCR may expect a high likelihood of return to full duty at a mean time to MMI of 7.6 months. At the time of follow-up, patients reported good outcomes using validated scoring scales, but subjective outcomes remained inferior to non-WC patients based on historical controls. Alcohol use was the only prognostic factor to show a significant association with return to restricted-duty employment and repair failure.

    Recent evidence indicates that caffeine may have a beneficial effect on cognitive decline and dementia. The current investigation assessed the effect of acute caffeine administration on working memory during the earliest stage of cognitive decline in elderly participants. The study includes consecutive 45 elderly controls and 18 individuals with mild cognitive impairment (MCI, 71.6 ± 4.7 years, 7 females). During neuropsychological follow-up at 18 months, 24 controls remained stable (sCON, 70.0 ± 4.3 years, 11 women), while the remaining 21 showed subtle cognitive deterioration (dCON, 73.4 ± 5.9 years, 14 women). All participants underwent an established 2-back working task in a crossover design of 200 mg caffeine versus placebo. Data analysis included task-related general linear model and functional connectivity tensorial independent component analysis. Working memory behavioral performances did not differ between sCON and dCON, while MCI was slower and less accurate than both control groups (p < 0.05). The dCON group had a less pronounced effect of acute caffeine administration essentially restricted to the right hemisphere (p < 0.05 corrected) and reduced default mode network (DMN) deactivation compared to sCON (p < 0.01 corrected). dCON cases are characterized by decreased sensitivity to caffeine effects on brain activation and DMN deactivation. These complex fMRI patterns possibly reflect the instable status of these cases with intact behavioral performances despite already existing functional alterations in neocortical circuits.

    Some of the most vulnerable children will need co-ordinated help from health, children's services and other agencies. Co-ordinated and joint working hinges on effective communication at all levels. Evidence shows that direct verbal communication is a more effective way to share concerns and that this should be followed up by written information. Yet barriers persist that prevent this from happening. Integrated health and social care teams are purported to break down professional and communication barriers. This paper reports on the evaluation of a pilot integrated model of health and social care in the North West of England. Such models can work and produce positive outcomes for children and families, but require full commitment from all parties. There are principles that need to be in place for this integrated model to achieve its aims and objectives, such as a robust governance framework that specifies the roles and responsibilities of each agency, managers and practitioners. Despite the model achieving its aim, the project was not as efficient as it could have been due to the lack of an integrated information technology system.

    The human brain can adapt to overcome injury even years after an initial insult. One hypothesis states that early brain injury survivors, by taking advantage of critical periods of high plasticity during childhood, should recover more successfully than those who suffer injury later in life. This hypothesis has been challenged by recent studies showing worse cognitive outcome in individuals with early brain injury, compared with individuals with later brain injury, with working memory particularly affected. We invited individuals who suffered perinatal brain injury (PBI) for an fMRI/diffusion MRI tractography study of working memory and hypothesized that, 30 years after the initial injury, working memory deficits in the PBI group would remain, despite compensatory activation in areas outside the typical working memory network. Furthermore we hypothesized that the amount of functional reorganization would be related to the level of injury to the dorsal cingulum tract, which connects medial frontal and parietal working memory structures. We found that adults who suffered PBI did not significantly differ from controls in working memory performance. They exhibited less activation in classic frontoparietal working memory areas and a relative overactivation of bilateral perisylvian cortex compared with controls. Structurally, the dorsal cingulum volume and hindrance-modulated orientational anisotropy was significantly reduced in the PBI group. Furthermore there was uniquely in the PBI group a significant negative correlation between the volume of this tract and activation in the bilateral perisylvian cortex and a positive correlation between this activation and task performance. This provides the first evidence of compensatory plasticity of the working memory network following PBI. SIGNIFICANCE STATEMENT Here we used the example of perinatal brain injury (PBI) associated with very preterm birth to study the brain's ability to adapt to injury sustained early in life. In

    The plant-specific NAC transcription factors have attracted particular attention because of their involvement in stress responses, senescence, and nutrient remobilization. The HvNAC005 gene of barley encodes a protein belonging to subgroup NAC-a6 of the NAC family. This study shows that HvNAC005 is associated with developmental senescence. It was significantly up-regulated following ABA treatment, supported by ABA-responsive elements in its promoter, but it was not up-regulated during dark-induced senescence. The C-termini of proteins closely related to HvNAC005 showed overall high divergence but also contained conserved short motifs. A serine- and leucine-containing central motif was essential for transcriptional activity of the HvNAC005 C-terminus in yeast. Over-expression of HvNAC005 in barley resulted in a strong phenotype with delayed development combined with precocious senescence. The over-expressing plants showed up-regulation of genes involved with secondary metabolism, hormone metabolism, stress, signalling, development, and transport. Up-regulation of senescence markers and hormone metabolism and signalling genes supports a role of HvNAC005 in the cross field of different hormone and signalling pathways. Binding of HvNAC005 to promoter sequences of putative target genes containing the T[G/A]CGT core motif was shown by direct protein–DNA interactions of HvNAC005 with promoters for two of the up-regulated genes. In conclusion, HvNAC005 was shown to be a strong positive regulator of senescence and so is an obvious target for the fine-tuning of gene expression in future attempts to improve nutrient remobilization related to the senescence process in barley.

    Progressive cerebellar ataxias are rare diseases during childhood, especially under 6 years of age. In a single family, three affected siblings exhibited Friedreich's-ataxia-like phenotypes before 2 years of age. They had progressive cerebellar atrophy, intellectual disability, and scoliosis. Although their phenotypes were similar to those observed in patients with autosomal recessive cerebellar ataxias, other phenotypes (e.g., seizure, movement disorders, ophthalmologic disturbance, cardiomyopathy, and cutaneous disorders) were not noted in this family. Whole-exome sequencing of the family members revealed one potential heterozygous mutation (c.1209delG, NM_181733.2; p.Met403IlefsX3, NP_859422.2) of the gene encoding conserved oligomeric Golgi complex subunit 5 (COG5). The heterozygous deletion at the fifth base in exon 12 of COG5 caused a frameshift and premature stop. Western blotting of COG5 proteins in the skin tissues from an affected proband showed a significantly decreased level of full length COG5 and smaller, aberrant COG5 proteins. We reported a milder form of COG5 defect showing Friedreich's-ataxia-like phenotypes without hypotonia, microcephaly, and short stature that were observed in most patients with COG5 defect. © 2017 The Korean Academy of Medical Sciences.

    The malignant form of atrophic papulosis (Köhlmeier-Degos disease) is a rare thrombo-occlusive vasculopathy that can affect multiple organ systems. Patients typically present with distinctive skin lesions reflective of vascular drop out. The small bowel is the most common internal organ involved, resulting in considerable morbidity and mortality attributable to ischemic microperforations. Determination of the presence of gastrointestinal lesions is critical in distinguishing systemic from the benign, cutaneous only disease and in identifying candidates for treatment. We describe an 18 year old male who first presented with cutaneous atrophic papulosis but became critically ill from small bowel microperforations. He had an almost immediate and dramatic response to treatment. Prior to his presentation with acute abdomen he had upper and lower endoscopy showing areas of nonspecific patchy erythema. At laparotomy, innumerable characteristic lesions with central pearly hue and erythematous border were seen. PubMed was used for a literature search using the keywords malignant atrophic papulosis, Degos disease, endoscopy, laparoscopy and laparotomy. This search yielded 200 articles which were further analyzed for diagnostic procedures and findings. Among the 200 articles we identified only 11 cases in which endoscopy was performed. Results of endoscopy and laparotomy in our patient with malignant atrophic papulosis were compared to those in the literature. Endoscopy of the gastrointestinal tract has shown gastritis and non-specific inflammation whereas laparoscopy shows white plaques with red borders on the serosal surface of the small bowel and the peritoneum. From personal communications with other physicians worldwide, we identified three additional unpublished cases in which endoscopy revealed only minimal changes while laparoscopy showed dramatic lesions. From our experience the endoscopic findings are often subtle and nonspecific, whereas laparascopy or laparotomy

    A report from the Partnership on Workplace Mental Health, a program of the American Psychiatric Foundation, supports the widely held view that intervening early in a psychiatric disability absence will result in earlier return to work and reduce the likelihood of permanent disability. Studies unfortunately reveal that patients with psychiatric illness do not receive a level of care consistent with evidence-based best practice. This article highlights the importance of early interventions that utilize best practices for anxiety disorders that impair an employee's occupational functioning. Behavioral Health Consulting Firm. Studies on occupational disability conclude that collaborative communication between clinicians, disability case managers, and the employer is important to facilitate a successful and timely return to work for employees with temporary psychiatric disability. Avoidance of preexisting workplace conflicts can undermine return to work. Undertreatment and ineffective treatment are common causes of delayed recovery from acute anxiety conditions. In addition, lack of urgency among clinicians regarding the crisis nature of absence from work due to psychiatric illness can contribute to lengthy and unnecessary absence from work. A basic understanding of the acute aspects of anxiety disorders can assist disability case managers working in collaboration with treating clinicians and employees in a successful and timely return to work when an anxiety condition leads to absence from work.

    Objective Depression symptom severity, the most commonly studied outcome in antidepressant treatment trials, accounts for only a small portion of burden related to major depression. While lost work productivity is the biggest contributor to depression’s economic burden, few studies have systematically evaluated the independent effect of treatment on work productivity and the relationship between changes in work productivity and longer-term clinical course. Method Work productivity was measured repeatedly by the Work Productivity and Activity Impairment (WPAI) self-report in 331 employed participants with major depression enrolled in the Combining Medications to Enhance Depression Outcomes (CO-MED) trial. Trajectories of change in work productivity during the first 6 weeks of treatment were identified and used to predict remission at 3 and 7 months. Results Participants reported reduced absence from work and increased work productivity with antidepressant treatment even after controlling for changes in depression severity. Three distinct trajectories of changes in work productivity were identified: 1) robust early improvement (24%), 2) minimal change (49%), and 3) high-impairment slight reduction (27%). As compared to other participants, those with robust improvement had 3–5 times higher remission rates at 3 months and 2–5 times higher remission rates at 7 months, even after controlling for select baseline variables and remission status at week 6. Conclusions In this secondary analysis, self-reported work productivity improved in depressed patients with antidepressant treatment even after accounting for depressive symptom reduction. Early improvement in work productivity is associated with much higher remission rates after 3 and 7 months of treatment. PMID:27523501

    2015-03-01

    Similarities and differences between the 2 main kinds of compound eye (apposition and superposition) are briefly explained before several promising topics for research on compound eyes are being introduced. Research on the embryology and molecular control of the development of the insect clear-zone eye with superposition optics is one of the suggestions, because almost all of the developmental work on insect eyes in the past has focused on eyes with apposition optics. Age- and habitat-related ultrastructural studies of the retinal organization are another suggestion and the deer cad Lipoptena cervi, which has an aerial phase during which it is winged followed by a several months long parasitic phase during which it is wingless, is mentioned as a candidate species. Sexual dimorphism expressing itself in many species as a difference in eye structure and function provides another promising field for compound eye researchers and so is a focus on compound eye miniaturization in very small insects, especially those that are aquatic and belong to species, in which clear-zone eyes are diagnostic or are tiny insects that are not aquatic, but belong to taxa like the Diptera for instance, in which open rather than closed rhabdoms are the rule. Structures like interommatidial hairs and glands as well as corneal microridges are yet another field that could yield interesting results and in the past has received insufficient consideration. Finally, the dearth of information on distance vision and depth perception is mentioned and a plea is made to examine the photic environment inside the foam shelters of spittle bugs, chrysales of pupae and other structures shielding insects and crustaceans. © 2014 Institute of Zoology, Chinese Academy of Sciences.

    2017-12-01

    This study explores the mental health needs of teachers and how these might impact on their capacity to provide early identification and intervention strategies to support their student's emotional well-being. The present study surveyed a sample of UK teachers (N = 320) to explore the impact of work-related stress on their mental health and their ability to provide early intervention support for their students. Our survey showed high levels of work-related stress due to time pressures and excessive workloads; many teachers failed to seek help for their stress often due to stigmatic attitudes and fear of negative response by senior management. Such factors led some to withdraw from taking on extra responsibilities with regard to student support and to consider leaving the teaching profession altogether. Coping mechanisms included the use of alcohol and tobacco, with only a small minority receiving access to psychological therapies. High levels of work-related stress in teachers can have serious consequences for their mental health and impede their ability to provide effective early intervention support for their student's emotional well-being. Improvements in mental health training for teachers and greater assistance for their own mental health needs are necessary. © 2015 Wiley Publishing Asia Pty Ltd.

    Workplace involvement in rehabilitation for patients with musculoskeletal pain may improve work ability. Convergence Dialogue Meeting (CDM) is a model aimed at helping the patient, the care giver, and the employer to support work ability and return-to-work. Our aim was to study the effect on work ability when adding a workplace dialogue according to CDM in physiotherapy practice for patients with pain in ordinary primary care. We conducted a prospective pairwise cluster randomised controlled trial (ClinicalTrials.gov ID: NCT02609750) in primary care involving 20 primary care rehabilitation units with 1-year follow-up. Adult patients with acute/subacute neck and back pain, worked ≥4 weeks past year and not currently on sick leave or no more than 60 days of sick leave and considered at-risk of sick leave were included (n = 352). All patients received structured physiotherapy and the intervention was the addition of CDM, delivered by the treating physiotherapist. The main confirmatory outcome, work ability (defined as working at least 4 consecutive weeks at follow-up), was assessed by a weekly short text message question on number of sick leave days past week. Work ability was reached by significantly more patients in the intervention group (108/127, 85%) compared with the reference group (127/171, 74%) (P = 0.02). The intervention increased the odds of having work ability at 1-year follow-up, also after adjustment for baseline health-related quality of life (odds ratio 1.85, confidence interval 1.01-3.38). We conclude that an early workplace dialogue in addition to structured physiotherapy improved work ability significantly.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    Objectives Early initiation of sex work is prevalent among female sex workers (FSWs) worldwide. The objectives of this study were to investigate if early initiation of sex work was associated with: (1) consistent condom use, (2) condom negotiation self-efficacy or (3) condom use norms among alcohol-using FSWs in Mombasa, Kenya. Methods In-person interviews were conducted with 816 FSWs in Mombasa, Kenya. Sample participants were: recruited from HIV prevention drop-in centres, 18 years or older and moderate risk drinkers. Early initiation was defined as first engaging in sex work at 17 years or younger. Logistic regression modelled outcomes as a function of early initiation, adjusting for drop-in centre, years in sex work, supporting others and HIV status. Results FSWs who initiated sex work early were significantly less likely to report consistent condom use with paying sex partners compared with those who initiated sex work in adulthood. There was no significant difference between groups in consistent condom use with non-paying sex partners. FSWs who initiated sex work early endorsed less condom negotiation self-efficacy with paying sex partners compared with FSWs who did not initiate sex work early. Conclusions Findings highlight a need for early intervention for at-risk youth and adolescent FSWs, particularly in relation to HIV sexual risk behaviours. Evidence-based interventions for adolescent FSWs or adult FSWs who began sex work in adolescence should be developed, implemented and evaluated. PMID:27217378

    2009-10-01

    This paper is a report of a longitudinal study of the relationship of working mothers' parenting style to their children's social competence and vocabulary/ motor/intellectual development. With an increasing number of women choosing to remain in the workforce after starting a family, there has been a concomitant increase in use of non-parental childcare facilities to help look after the child while the mother is at work. This increase in non-parental care has led to a dramatic change in the traditional child-rearing environment. Long-term investigations were conducted over a period of 2 years in 41 Japanese government-licensed childcare facilities. Child development was evaluated by childcare professionals and parenting style was assessed by questionnaire. A total of 504 children and their mothers participated in the study. Data collection was carried out in 2004 and 2006. We found that the changes in parenting style were statistically significantly related to children's development after 2 years. For instance, changes in the parent-child playing routine contributed to the child's social competence (odds ratio = 11.088). Variation in working mothers' disciplinary practices was also associated with children's vocabulary development after 2 years (odds ratio = 2246). Working mothers should increase interactions with their children in their free time to reduce the risk of developmental delay. Daily childcare support provided by family members or social organizations for long-term working mothers is helpful in mediating the negative relationship of mothers' working with children's development.

    In this study, observed maternal positive engagement and perception of work-family spillover were examined as mediators of the association between maternal nonstandard work schedules and children’s expressive language outcomes in 231 African American families living in rural households. Mothers reported their work schedules when their child was 24 months of age and children’s expressive language development was assessed during a picture book task at 24 months and with a standardized assessment at 36 months. After controlling for family demographics, child, and maternal characteristics, maternal employment in nonstandard schedules at the 24 month timepoint was associated with lower expressive language ability among African American children concurrently and at 36 months of age. Importantly, the negative association between nonstandard schedules and children’s expressive language ability at 24 months of age was mediated by maternal positive engagement and negative work-family spillover, while at 36 months of age, the association was mediated only by negative work-family spillover. These findings suggest complex links between mothers’ work environments and African American children’s developmental outcomes. PMID:23459591

    2014-08-01

    From the very beginning of his scientific career Poincaré found an attentive reader in Weierstrass. To support this claim, in the apparent lack of direct relationship between them, in the present paper I take into account indirect sources such as Mittag-Leffler's letters to Poincaré and Weierstrass, and Weierstrass's letters to S. Kovalevskaya and H. A. Schwarz. These letters provide evidence of Weierstrass's interest in the achievements of the young French mathematician, including in particular his early statement of the uniformisation theorem. In addition, such subjects as gap series, the Poincaré-Volterra theorem and the n-body problem are also discussed.

  1. Early talk about the past revisited: affect in working-class and middle-class children's co-narrations.

    PubMed

    Burger, L K; Miller, P J

    1999-02-01

    This study contributes to our understanding of sociocultural variation in children's early storytelling by comparing co-narrations produced by children and their families from two European-American communities, one working-class and one middle-class. Six children from each community were observed in their homes at 2;6 and 3;0 years of age, yielding a corpus of nearly 400 naturally-occurring co-narrations of past experience. Analyses of generic properties, content, and emotion talk revealed a complex configuration of similarities and differences. Working-class and middle-class families produced co-narrations that were similar in referential/evaluative functions and temporal structure, with a preponderance of positive content. Working-class families produced twice as many co-narrations as their middle-class counterparts, produced more negative emotion talk, and used more dramatic language for conveying negative emotional experience. These findings suggest that (1) differentiation between working-class and middle-class communities in the content of early narratives may occur primarily with respect to negative experience and (2) researchers need to go beyond emotion state terms in order to accurately represent sociocultural variation in personal storytelling.

    The aim of the present study was to examine whether the degenerative and morphological changes of articular cartilage in early stage knee osteoarthritis (OA) occurred equally for both femoral- and tibial- or patellar- articular cartilage using magnetic resonance imaging (MRI)-based analyses. This cross-sectional study was approved by the ethics committee of our university. Fifty patients with early stage painful knee OA were enrolled. The patients underwent 3.0 T MRI on the affected knee joint. Healthy volunteers who did not show MRI-based OA changes were also recruited as controls (n = 19). The degenerative changes of the articular cartilage were quantified by a T2 mapping analysis, and any structural changes were conducted using Whole Organ Magnetic Resonance Imaging Score (WORMS) technique. All patients showed MRI-detected OA morphological changes. The T2 values of femoral condyle (FC) (P < 0.0001) and groove (P = 0.0001) in patients with early stage knee OA were significantly increased in comparison to those in the control, while no significant differences in the T2 values of patellar and tibial plateau (TP) were observed between the patients and the control. The WORMS cartilage and osteophyte scores of the femoral articular cartilage were significantly higher than those in the patellar- (P = 0.001 and P = 0.007, respectively) and tibial- (P = 0.0001 and P < 0.0001, respectively) articular cartilage in the patients with early stage knee OA. The degradation and destruction of the femoral articular cartilage demonstrated a greater degree of deterioration than those of the tibial- and patellar- articular cartilage in patients with early stage knee OA.

    A large corpus of research indicates exposure to stress impairs cognitive abilities, specifically executive functioning dependent on the prefrontal cortex (PFC). We collected structural MRI scans (n=61), well-validated assessments of executive functioning, and detailed interviews assessing stress exposure in humans, to examine whether cumulative life stress affected brain morphometry and one type of executive functioning, spatial working memory, during adolescence—a critical time of brain development and reorganization. Analysis of variations in brain structure revealed that cumulative life stress and spatial working memory were related to smaller volumes in the PFC, specifically prefrontal gray and white matter between the anterior cingulate and the frontal poles. Mediation analyses revealed that individual differences in prefrontal volumes accounted for the association between cumulative life stress and spatial working memory. These results suggest that structural changes in the PFC may serve as a mediating mechanism through which greater cumulative life stress engenders decrements in cognitive functioning. PMID:22674267

    Kuo, Janet Chen-Lan; Raley, R Kelly

    2016-06-01

    Using data from the NLSY 97, this paper investigates how work characteristics (earnings and autonomy) shape young adults' transition to first marriage separately for men and women. The results suggest that earnings are positively associated with marriage and that this association is as strong for women as men in their mid-to-late twenties. Additionally, occupational autonomy-having the control over one's own work structure-facilitates entry into first marriage for women in their mid-to late-20s but, for men, occupational autonomy is not associated with marriage at these ages. These results suggest that even as women's earnings are increasingly important for marriage, other aspects of work are also important for stable family formation.

    The ageing society and recent policy changes may lead to an increase of older workers with chronic diseases in the workforce. To date, it is unclear whether workers with chronic diseases have specific needs while employed. The aim of this study is to explore the differences in determinants of working until retirement compared to a reference group who have transitioned to early retirement among workers with and without chronic diseases. Dutch workers aged 57-62 years ( n = 2445) were selected from an existing prospective cohort study, 'STREAM'. The potential determinants were categorized into: individual, health, work-related and social factors. Logistic regression analyses were performed to determine the associations between these determinants and working until retirement - once for workers with and once for those without chronic diseases. To test differences, we included an interaction term between the determinant and the covariate 'having a chronic disease yes/no' in the analyses of the total population. In total, 1652 (68%) persons were employed from 2011 to 2013. The majority of the determinants appeared to be similar for workers with or without a chronic disease; the interaction terms for these determinants and the covariate 'having a chronic disease' showed a p-value higher than 0.05, except for one individual factor (i.e. mastery) and one work-related factor (i.e. autonomy), which showed a p-value below 0.05. Higher mastery and higher autonomy were statistically significantly associated with working until retirement for those with chronic diseases, whereas they were not for those without chronic diseases. Differences between workers with and without chronic diseases may exist for working until a statutory retirement age. Interventions aimed at encouraging work participation of older workers should make a distinction between the two groups. Autonomy at work and mastery were found to be factors that may promote work participation until higher age, specifically

    During the eighteenth century, orders of nursing sisters took on an expanded role in the rural areas of Brittany. This article explores the impact of religious change on the medical activities of these women. While limits were placed on the medical practice of unlicensed individuals, areas of new opportunity for nuns as charitable practitioners were created by devout nobles throughout the eighteenth century. These nuns provided comprehensive care for the sick poor on their patrons' estates, acting not only as nurses, but also in lieu of physicians, surgeons, and apothecaries. This article argues that the medical knowledge and expertise of these sisters from the nursing orders were highly valued by the elites of early modern Brittany. PMID:21724643

  16. The early effects of code 405 work rules on attitudes of orthopaedic residents and attending surgeons.

    PubMed

    Zuckerman, Joseph D; Kubiak, Eric N; Immerman, Igor; Dicesare, Paul

    2005-04-01

    The impact of strict enforcement of Section 405 of the New York State Public Health Code to restrict resident work to eighty hours per week and the adoption of a similar policy by the Accreditation Council on Graduate Medical Education in 2002 for orthopaedic residency training have not been evaluated. Adoption of these rules has created accreditation as well as staffing problems and has generated controversy in the surgical training community. The purposes of this study were (1) to evaluate the attitudes of orthopaedic residents and attending surgeons toward the Code 405 work-hour regulations and the effect of those regulations on the perceived quality of residency training, quality of life, and patient care and (2) to quantify the effect of the work-hour restrictions on the actual number of hours worked. We administered a thirty-four-question Likert-style questionnaire to forty-eight orthopaedic surgery residents (postgraduate years [PGY]-2 through 5) and a similar twenty-nine-question Likert-style questionnaire to thirty-nine orthopaedic attending surgeons. All questionnaires were collected anonymously and analyzed. Additionally, resident work hours before and after strict enforcement of the Code 405 regulations were obtained from resident time sheets. The average weekly work hours decreased from 89.25 to 74.25 hours for PGY-2 residents and from 86.5 to 73.25 hours for PGY-3 residents, and they increased from 61.5 to 68.5 hours for PGY-4 residents. Residents at all levels felt that they had increased time available for reading. There was general agreement between attending and resident surgeons that their operating experience had been negatively impacted. Senior residents thought that their education had been negatively affected, while junior residents thought that their operating experience in general had been negatively affected. Senior residents and attending surgeons felt that continuity of care had been negatively impacted. All agreed that quality of life

    In this study, the authors used an attachment framework to examine how drug-dependent mothers’ early bonding experience, depression, illicit drug use, and perceived support work together to influence the family environment. The authors hypothesized that (a) depression and drug use function as proxies for a stronger risk factor, the perceived absence of support available in everyday life, and (b) associations between mothers’ early bonding experience and family environment are mediated by perceptions of support and nurture available in everyday life. The authors used a “building block” analytic approach and data collected from 125 mothers enrolled in methadone maintenance to test hypotheses. Both hypotheses were confirmed for 1 outcome, family adaptability. For the 2nd outcome, family cohesion, only perceived support was a significant predictor. Although preliminary, the findings suggest that perceptions of relationships in everyday life play a critical role in the etiology of drug-dependent mothers’ parenting. PMID:16060738

  18. A selective egocentric topographical working memory deficit in the early stages of Alzheimer's disease: a preliminary study.

    The aim of this study was to determine whether an egocentric topographical working memory (WM) deficit is present in the early stages of Alzheimer's disease (AD) with respect to other forms of visuospatial WM. Further, we would investigate whether this deficit could be present in patients having AD without topographical disorientation (TD) signs in everyday life assessed through an informal interview to caregivers. Seven patients with AD and 20 healthy participants performed the Walking Corsi Test and the Corsi Block-Tapping Test. The former test requires memorizing a sequence of places by following a path and the latter is a well-known visuospatial memory task. Patients with AD also performed a verbal WM test to exclude the presence of general WM impairments. Preliminary results suggest that egocentric topographical WM is selectively impaired, with respect to visuospatial and verbal WM, even without TD suggesting an important role of this memory in the early stages of AD. © The Author(s) 2014.

    Alarm about the increasing prevalence of childhood obesity has focussed attention on individual lifestyle behaviours that may contribute to unhealthy weight. More distal predictors such as maternal employment may also be implicated since working mothers have less time to supervise children's daily activities. The research reported here used two waves of data from the Longitudinal Study of Australian Children to investigate whether mothers' hours in paid work shape young children's television viewing, snacking and physical activity, and through those lifestyle behaviours, children's weight at ages 4-5 years and 6-7 years. At both ages, children's lifestyle behaviours were interrelated and associated with weight status. Cross-sectional analysis confirmed small, direct associations between longer hours of maternal employment and child weight at age 4-5 years, but not with child's weight measured two years later. In both the cross-sectional and prospective analyses, the children of mothers who worked part-time watched less television and were less likely to be overweight than children of mothers who were not employed or who worked full-time. While associations were small, they remained significant after adjustment for maternal weight, household income and other factors. The combination of direct and indirect relationships between mothers' work hours and the weight status of their young children provides additional support to calls for family-friendly work policies as an important means for promoting healthy family lifestyles and early childhood wellbeing.

  20. The different oscillation patterns of alpha band in the early and later stages of working memory maintenance.

    A putative functional role for alpha oscillations in working memory remains controversial. However, recent evidence suggests that such oscillation may reflect distinct phases of working memory processing. The present study investigated alpha band (8-13Hz) activity during the maintenance stage of working memory using a modified Sternberg working memory task. Our results reveal that alpha power was concentrated primarily in the occipital cortex and was decreased during the early stage of maintenance (0-600ms), and subsequently increased during the later stage of maintenance (1000-1600ms). We suggest that reduced alpha power may be involved in focused attention during the working memory maintenance, whereas increased alpha power may reflect suppression of visual stimuli to facilitate internal processing related to the task. This interpretation is generally consistent with recent reports suggesting that variations in alpha power are associated with the representation and processing of information in the discrete time intervals during the working memory maintenance.

    Neuroimaging studies have demonstrated that activity patterns in early visual areas predict stimulus properties actively maintained in visual working memory. Yet, the mechanisms by which such information is represented remain largely unknown. In this study, observers remembered the orientations of 4 briefly presented gratings, one in each quadrant of the visual field. A 10Hz Transcranial Magnetic Stimulation (TMS) triplet was applied directly at stimulus offset, or midway through a 2-second delay, targeting early visual cortex corresponding retinotopically to a sample item in the lower hemifield. Memory for one of the four gratings was probed at random, and participants reported this orientation via method of adjustment. Recall errors were smaller when the visual field location targeted by TMS overlapped with that of the cued memory item, compared to errors for stimuli probed diagonally to TMS. This implied topographic storage of orientation information, and a memory-enhancing effect at the targeted location. Furthermore, early pulses impaired performance at all four locations, compared to late pulses. Next, response errors were fit empirically using a mixture model to characterize memory precision and guess rates. Memory was more precise for items proximal to the pulse location, irrespective of pulse timing. Guesses were more probable with early TMS pulses, regardless of stimulus location. Thus, while TMS administered at the offset of the stimulus array might disrupt early-phase consolidation in a non-topographic manner, TMS also boosts the precise representation of an item at its targeted retinotopic location, possibly by increasing attentional resources or by injecting a beneficial amount of noise.

    Converging preclinical and human evidence indicates that the decline in ovarian estradiol production during the menopausal transition may play a mechanistic role in the neuronal changes that occur early in the aging process. Here, we present findings from a population-based fMRI study characterizing regional and network-level differences in working memory (WM) circuitry in midlife men and women (N = 142; age range 46-53), as a function of sex and reproductive stage. Reproductive histories and hormonal evaluations were used to determine menopausal status. Participants performed a verbal WM task during fMRI scanning. Results revealed robust differences in task-evoked responses in dorsolateral prefrontal cortex and hippocampus as a function of women's reproductive stage, despite minimal variance in chronological age. Sex differences in regional activity and functional connectivity that were pronounced between men and premenopausal women were diminished for postmenopausal women. Critically, analyzing data without regard to sex or reproductive status obscured group differences in the circuit-level neural strategies associated with successful working memory performance. These findings underscore the importance of reproductive age and hormonal status, over and above chronological age, for understanding sex differences in the aging of memory circuitry. Further, these findings suggest that early changes in working memory circuitry are evident decades before the age range typically targeted in cognitive aging studies. © The Author 2016.

    One of the features of both adult-onset and developmental forms of amnesia resulting from bilateral medial temporal lobe damage, or even from relatively selective damage to the hippocampus, is the sparing of working memory. Recently, however, a number of studies have reported deficits on working memory tasks in patients with damage to the hippocampus and in macaque monkeys with neonatal hippocampal lesions. These studies suggest that successful performance on working memory tasks with high memory load require the contribution of the hippocampus. Here we compared performance on a working memory task (the Self-ordered Pointing Task), between patients with early onset hippocampal damage and a group of healthy controls. Consistent with the findings in the monkeys with neonatal lesions, we found that the patients were impaired on the task, but only on blocks of trials with intermediate memory load. Importantly, only intermediate to high memory load blocks yielded significant correlations between task performance and hippocampal volume. Additionally, we found no evidence of proactive interference in either group, and no evidence of an effect of time since injury on performance. We discuss the role of the hippocampus and its interactions with the prefrontal cortex in serving working memory. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  5. Management of early renal anaemia: diagnostic work-up, iron therapy, epoetin therapy.

    PubMed

    Van Wyck, D B

    2000-01-01

    Effective management of early anaemia in the course of chronic renal insufficiency requires the following: (i) implementing an efficient diagnostic strategy to exclude common contributing factors; (ii) initiating epoetin therapy for the majority of patients; for and (iii) ensuring adequate iron supply erythropoiesis. Diagnostic inquiry is warranted whenever the haemoglobin concentration is below the normal range adjusted for age and gender. The most efficient diagnostic approach is to assume erythropoietin deficiency, exclude iron deficiency, and pursue further diagnostic tests only when red-cell indices are abnormal or when leukopenia or thrombocytopenia are also present. Macrocytosis should prompt an inquiry into alcoholism, B12 deficiency, or folate deficiency. Microcytosis suggests iron deficiency or thalassaemia. Associated cytopenias raise the possibility of alcohol toxicity, pernicious anaemia, malignancy, or myelodysplastic syndrome. Epoetin therapy is warranted whenever the haemoglobin concentration has fallen below 10.0 g/dl. To initiate therapy prior to dialysis, epoetin should be administered at an average dose of 100 IU/kg/week (80-120 IU/kg/week, 50-150 IU/kg/ week) by subcutaneous injection. Haemoglobin concentration should be monitored every 2 weeks and the epoetin dose adjusted by increments or decrements of 25% to maintain a rate of rise of haemoglobin concentration of 0.2-0.6 g/dl (0.3 0.6 g/dl/week, 0.2-0.5 g/dl/week). When the target range is achieved, the dose of epoetin should be continually adjusted to maintain a stable haemoglobin concentration. Transferrin saturation and ferritin concentration should be monitored monthly, and sufficient iron provided to maintain transferrin saturation above 20%. The lower the haemoglobin concentration, the greater the likelihood that future intravenous iron will be required. Oral iron supplements should be avoided, since they are costly, ineffective, and troublesome to patients. Finally, a blunted

    Up to 160,000 people incur traumatic brain injury (TBI) each year in the UK. TBI can have profound effects on many areas of human functioning, including participation in work. There is limited evidence of the clinical effectiveness and cost-effectiveness of vocational rehabilitation (VR) after injury to promote early return to work (RTW) following TBI. To assess the feasibility of a definitive, multicentre, randomised controlled trial (RCT) of the clinical effectiveness and cost-effectiveness of early, specialist VR plus usual care (UC) compared with UC alone on work retention 12 months post TBI. A multicentre, feasibility, parallel-group RCT with a feasibility economic evaluation and an embedded mixed-methods process evaluation. Randomisation was by remote computer-generated allocation. Three NHS major trauma centres (MTCs) in England. Adults with TBI admitted for > 48 hours and working or studying prior to injury. Early specialist TBI VR delivered by occupational therapists (OTs) in the community using a case co-ordination model. Self-reported RTW 12 months post randomisation, mood, functional ability, participation, work self-efficacy, quality of life and work ability. Feasibility outcomes included recruitment and retention rates. Follow-up was by postal questionnaires in two centres and face to face in one centre. Those collecting data were blind to treatment allocation. Out of 102 target participants, 78 were recruited (39 randomised to each arm), representing 39% of those eligible and 5% of those screened. Approximately 2.2 patients were recruited per site per month. Of those, 56% had mild injuries, 18% had moderate injuries and 26% had severe injuries. A total of 32 out of 45 nominated carers were recruited. A total of 52 out of 78 (67%) TBI participants responded at 12 months (UC, n  = 23; intervention, n  = 29), completing 90% of the work questions; 21 out of 23 (91%) UC respondents and 20 out of 29 (69%) intervention participants returned to

    To explore the association between the initial 60 days of prescriptions for psychotropic medications and final workers' compensation claim outcomes. A cohort of 11,394 claimants involved in lost time injuries between 1999 and 2002 were followed through December 31, 2009. Logistic regressions and Cox Proportional Hazard Models were used in the analysis. The initial 60 days of prescriptions for psychotropic medications were significantly associated with a final claim cost at least $100,000. Odds ratios were 1.88 for short-acting opioids, 2.14 for hypnotics, antianxiety agents, or antidepressants, and 3.91 for long-acting opioids, respectively. Significant associations were also found between decreased time lost from work and decreased claim closures during the study period. Early prescription of opioids and other psychotropic drugs may be useful predictors of high claim costs and time lost from work.

  8. Obesity in show cats.

    Obesity is an important disease with a high prevalence in cats. Because obesity is related to several other diseases, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain cat breeds has been suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, 268 cats of 22 different breeds investigated by determining their body condition score (BCS) on a nine-point scale by inspection and palpation, at two different cat shows. Overall, 45.5% of the show cats had a BCS > 5, and 4.5% of the show cats had a BCS > 7. There were significant differences between breeds, which could be related to the breed standards. Most overweight and obese cats were in the neutered group. It warrants firm discussions with breeders and cat show judges to come to different interpretations of the standards in order to prevent overweight conditions in certain breeds from being the standard of beauty. Neutering predisposes for obesity and requires early nutritional intervention to prevent obese conditions. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

    Object permanence is considered the earliest method for assessing working memory. Factors affecting object permanence performance in a sample of two hundred and thirty-three 18- to 22-month olds born with extremely low birth weight were examined. It was hypothesized that object permanence would be directly related to emotional and attention regulation, that children with lower birth weight and higher illness severity would have more difficulty on the object permanence task, and that no ethnic/racial differences would be found, as this is considered a culturally unbiased task. Attainment of object permanence had a significant positive association with emotional and attention regulation, even after controlling the medical severity and socioeconomic factors. More girls than boys passed the object permanence items. There was no ethnic/racial difference on object permanence. Our findings indicate that object permanence may be a culturally fair way of assessing development, and emotional and attention regulation are potential avenues of intervention for such skill.

    In late 2006, SDN Children's Services, an Australian not-for-profit provider of services for children, families and communities, engaged a research team that was 'embedded' within the organisation for 1 year. This action represented a significant investment of resources, such as staff time and organisational funds, and demonstrates SDN's strong commitment to research and evaluation as a means of supporting organisational learning and development. This paper highlights the innovative nature of the approach by positioning the role of the embedded researcher within the current theoretical and socio-political context. It also provides evidence of the success of the approach by reporting on the findings of a study that investigated staff's experiences of being involved in this type of collaborative investigation of their work. I argue that the employment of an embedded researcher can have positive benefits both for the organisation and the practitioners--but who the researchers are really matters.

    Before World War 1 both the United States of America and Australia had rather rudimentary medical systems. Enterprising practitioners in both countries tended to look to continental Europe (especially Germany) and the United Kingdom as places of medical renown. The outbreak of World War 1 changed this but also enabled doctors from both the United States and Australia to work in military hospitals in Europe. The interactions that occurred were important for their professional development and led to some close associations between American and antipodean doctors. Examples of these were the experiences of Harvey Cushing, a burgeoning American neurosurgeon, which he recounted in his diary. His commentary merits close inspection and analysis. An account of some of Cushing's Australian connections post World War 1 is given in Part 2 (in press). Copyright 2009 Elsevier Ltd. All rights reserved.

    Background The Florida Maternal, Infant, and Early Childhood Home Visiting (MIECHV) program delivers evidence-based home visiting services to over 1400 families each year. Home visitors are integral in providing resources for families to promote healthy pregnancy, child development, family wellness, and self-sufficiency. Due to the nature of this work, home visitors experience work-related pressures and stressors that can impact staff well-being and retention. Objectives The purpose of this study was to understand primary sources of work-related stress experienced by home visitors, subsequent effects on their engagement with program participants, and to learn of coping mechanisms used to manage stress. Methods In 2015, Florida MIECHV program evaluators conducted ten focus groups with 49 home visitors during which they ranked and discussed their top sources of work-related stress. Qualitative analysis was conducted to identify emergent themes in work-related stressors and coping/supports. Results Across all sites, the burden of paperwork and data entry were the highest ranked work-related stressors perceived as interfering with home visitors' engagement with participants. The second-highest ranked stressors included caseload management, followed by a lack of resources for families, and dangerous environments. Home visitors reported gratification in their helping relationships families, and relied on coworkers or supervisors as primary sources of workplace support along with self-care (e.g. mini-vacations, recreation, and counseling). Conclusions for practice Florida MIECHV home visitors across all ten focus groups shared similar work-related stressors that they felt diminished engagement with program participants and could impact participant and staff retention. In response, Florida MIECHV increased resources to support home visitor compensation and reduce caseloads, and obtained a competitive award from HRSA to implement a mindfulness-based stress reduction

    In our studies of the effects of unemployment in the early working life of men in a British national birth cohort we have shown elsewhere that this experience was part of a longer term accumulation of social and health disadvantage. This present study asks whether men's unemployment also inflicted potential longterm damage to future socio-economic chances and health. We therefore constructed indicators of socio-economic circumstances and health at 33 years from factors already shown to be associated with health in later life. For the socio-economic indicator we used a combination of income, occupational status and home ownership and described this as socio-economic capital. For the health indicator we combined scores of body mass index, leisure time exercise, frequency of eating fresh fruit and of smoking, and described this as health capital. After controlling for pre-labour market socio-economic and health factors, prolonged unemployment is shown here to reduce significantly both socio-economic and health capital by age 33 years. We conclude that the experience of prolonged unemployment early in the working life of this population of young men looks likely to have a persisting effect on their future health and socio-economic circumstances.

    Support of others is a key factor for mothers who choose to breastfeed their infants, including those who balance work outside the home and breastfeeding. However, little research has been done to understand how maternal support during the postpartum period impacts mothers' ability to later balance work and breastfeeding, in particular full-time work and exclusive breastfeeding. The results of this qualitative study indicate that the timing of support plays a key role in mothers' ability to successfully overcome barriers during the early postpartum period, thus building maternal self-efficacy in addressing problems encountered when they return to work. To understand the experience of low-income women who successfully balance full-time work and exclusive breastfeeding for the recommended 6 months, interviews were conducted with women who met study criteria for income level, work status, and exclusive breastfeeding. Breastfeeding peer counselors were also interviewed as key informants. Interviews were recorded, transcribed, and coded for themes. The results of both sets of interviews were triangulated with a focused literature review to assure the soundness of the qualitative analysis. Timing of support included acute support, such as help establishing a successful latch needed during the first 2 weeks after delivery, to deal with breastfeeding problems that mothers perceived as being mentally and emotionally overwhelming and longer-term support needed to overcome problems perceived as being less intense. The research invites further exploration into the relationship between breastfeeding support provided by mothers' support system, including healthcare professionals, during the postpartum period and rates of breastfeeding duration and exclusivity.

    This study examined pathways to retirement and the role of circumstances at work and at home (including the introduction of financially-enhanced early retirement schemes) on retirement-related decision-making. In-depth qualitative interviews were conducted within 2 years of retirement with 59 British civil servants participating in the Whitehall II Study. Focusing on the experiences of 33 interviewees who spontaneously discussed "early retirement" we identified three pathways to retirement (non-applicants, successful applicants, and unsuccessful applicants for early retirement) each influenced by a range of complementary positive and negative factors at work and at home. The early retirement schemes influenced the balance between these factors in three ways: by encouraging participants to reflect on (and reconsider) existing retirement plans; by offering financial incentives to retire early; and because they were part of the ongoing process of restructuring and downsizing within the Civil Service which was accompanied by a perceived deterioration in conditions at work.

    The United States lacks timely reliable mechanisms for assessing the professional work of subspecialty physicians. The aim was to use early-career members of The Endocrine Society as a model to estimate subspecialty physician involvement in patient care, teaching, research, and administration among clinical, academic, federal, and pharmaceutical/biotech workplaces and to assess the workforce for research within individual workplaces. Physicians joining The Endocrine Society from 1991-2005 and residing in North America were invited to complete a Web-based survey. This report relies on 817 early-career endocrinologists or 29.6% of eligible respondents. Respondents from all types of workplaces engaged in patient care, teaching, research, and administration. The time committed to the four tasks, however, differed significantly among workplaces. Research (basic, translational, disease, patient, population, and prevention) was accomplished within all workplaces, but the scope and scale of investigative work was employer dependent. Recipients of National Institutes of Health K08/23 awards succeeded in receiving federal research project grants (P < 0.001). Respondents associated research with lowered incomes, a perception validated by an estimated drop in annual earnings of 2.8% per half-day spent on research (P < 0.001). Women in academic settings earned less than men (P < 0.01) and were less likely to occupy tenure-eligible positions (P < 0.01). Web-based surveys offer a simple tool for estimating the work of subspecialty physicians and provide a framework for improving biomedical investigation. Several interventions should be considered for endocrinology: recruit physicians from underrepresented demographic groups, increase K08/23 awards, incentivize investigative careers, and improve the national infrastructure for biomedical research.

    Objectives Spinal (ie, back and neck) pain often develops as early as during adolescence and can set a trajectory for later life. However, whether early-life spinal-pain-related behavioral responses of missing school/work are predictive of future work absenteeism is yet unknown. We assessed the association of adolescent spinal-pain-related work or school absenteeism with early adulthood work absenteeism in a prospective population-based cohort. Methods Six year follow-up data from the Western Australian Pregnancy Cohort (Raine) study were used (N=476; with a 54% response rate). At age 17, participants reported spinal pain (using the Nordic questionnaire) and adolescent spinal-pain-related work/school absenteeism (with a single item question). Annual total and health-related work absenteeism was assessed with the Health and Work Performance questionnaire distributed in four quarterly text messages during the 23rd year of age. We modelled the association of adolescent spinal-pain-related absenteeism with work absenteeism during early adulthood, using negative binomial regression adjusting for sex, occupation and comorbidities. Results Participants with adolescent low-back or neck pain with work/school absenteeism reported higher total work absenteeism in early adulthood [148.7, standard deviation (SD) 243.4 hours/year], than those without pain [43.7 (SD 95.2) hours/year); incidence rate ratio 3.4 (95% CI 1.2-9.2)]. Comparable findings were found when considering low-back and neck separately, and when considering health-related absenteeism. Conclusions We found a more than three-fold higher risk of work absenteeism in early adulthood among those with adolescent spinal-pain-related absenteeism, compared to those without. These findings suggest that, to keep a sustainable workforce, pain prevention and management should focus on pain-related behaviors as early as in adolescence.

    Early initiation of sex work is prevalent among female sex workers (FSWs) worldwide. The objectives of this study were to investigate if early initiation of sex work was associated with: (1) consistent condom use, (2) condom negotiation self-efficacy or (3) condom use norms among alcohol-using FSWs in Mombasa, Kenya. In-person interviews were conducted with 816 FSWs in Mombasa, Kenya. Sample participants were: recruited from HIV prevention drop-in centres, 18 years or older and moderate risk drinkers. Early initiation was defined as first engaging in sex work at 17 years or younger. Logistic regression modelled outcomes as a function of early initiation, adjusting for drop-in centre, years in sex work, supporting others and HIV status. FSWs who initiated sex work early were significantly less likely to report consistent condom use with paying sex partners compared with those who initiated sex work in adulthood. There was no significant difference between groups in consistent condom use with non-paying sex partners. FSWs who initiated sex work early endorsed less condom negotiation self-efficacy with paying sex partners compared with FSWs who did not initiate sex work early. Findings highlight a need for early intervention for at-risk youth and adolescent FSWs, particularly in relation to HIV sexual risk behaviours. Evidence-based interventions for adolescent FSWs or adult FSWs who began sex work in adolescence should be developed, implemented and evaluated. Published by the BMJ Publishing Group Limited.

    Over one million people sustain traumatic brain injury each year in the UK and more than 10 % of these are moderate or severe injuries, resulting in cognitive and psychological problems that affect the ability to work. Returning to work is a primary rehabilitation goal but fewer than half of traumatic brain injury survivors achieve this. Work is a recognised health service outcome, yet UK service provision varies widely and there is little robust evidence to inform rehabilitation practice. A single-centre cohort comparison suggested better work outcomes may be achieved through early occupational therapy targeted at job retention. This study aims to determine whether this intervention can be delivered in three new trauma centres and to conduct a feasibility, randomised controlled trial to determine whether its effects and cost effectiveness can be measured to inform a definitive trial. Mixed methods study, including feasibility randomised controlled trial, embedded qualitative studies and feasibility economic evaluation will recruit 102 people with traumatic brain injury and their nominated carers from three English UK National Health Service (NHS) trauma centres. Participants will be randomised to receive either usual NHS rehabilitation or usual rehabilitation plus early specialist traumatic brain injury vocational rehabilitation delivered by an occupational therapist. The primary objective is to assess the feasibility of conducting a definitive trial; secondary objectives include measurement of protocol integrity (inclusion/exclusion criteria, intervention adherence, reasons for non-adherence) recruitment rate, the proportion of eligible patients recruited, reasons for non-recruitment, spectrum of TBI severity, proportion of and reasons for loss to follow-up, completeness of data collection, gains in face-to-face V s postal data collection and the most appropriate methods of measuring primary outcomes (return to work, retention) to determine the sample size for a

    The relationship between a composite measure of insomnia and occupational or fatal accidents has been investigated previously; however, little is known regarding the effect of various insomnia symptoms on minor non-fatal accidents during work and leisure time. We investigated the predicting role of insomnia symptoms on minor non-fatal accidents during work and leisure time. Data from the 2005 Taiwan Social Development Trend Survey of 36,473 Taiwanese aged ≥18 years were analyzed in 2013. Insomnia symptoms, including difficulty in initiating sleep (DIS), difficulty in maintaining sleep (DMS), early morning awakening (EMA), and nonrestorative sleep (NRS) were investigated. A minor non-fatal accident was defined as any mishap such as forgetting to turn off the gas or faucets, accidental falls, and abrasions or cuts occurring during work and leisure time in the past month that do not require immediate medical attention. Multivariable logistic regression was performed to assess the odds ratios (ORs) and associated 95% confidence interval (CI) of minor non-fatal accidents (as a binary variable) for each insomnia symptom compared with those of people presenting no symptoms, while controlling for possible confounders. EMA and NRS increased the odds of minor non-fatal accidents occurring during work and leisure time (adjusted OR=1.19, 95% CI=1.08-1.32 and adjusted OR=1.27, 95% CI=1.17-1.37, respectively). EMA and NRS are two symptoms that are significantly associated with an increased likelihood of minor non-fatal accidents during work and leisure time after adjusting for of a range of covariates.

    To examine work absenteeism, job disruptions, and perceived productivity loss and factors associated with each outcome in young adults living with systemic lupus erythematosus (SLE) and juvenile arthritis (JA). One hundred forty-three young adults, ages 18-30 years with SLE (54.5%) and JA (45.5%), completed an online survey of work experiences. Demographic, health (e.g., fatigue, disease activity), psychosocial (e.g., independence, social support), and work context (e.g., career satisfaction, job control, self-disclosure) information was collected. Participants were asked about absenteeism, job disruptions, and perceived productivity loss in the last 6 months. Log Poisson regression analyses examined factors associated with work outcomes. A majority of participants (59%) were employed and reported a well-managed health condition. Employed respondents were satisfied with their career progress and indicated moderate job control. More than 40% of participants reported absenteeism, job disruptions, and productivity loss. Greater job control and self-disclosure, and less social support, were related to a higher likelihood of absenteeism. More disease activity was related to a greater likelihood of reporting job disruptions. Lower fatigue and higher job control were associated with a reduced likelihood of a productivity loss. Young adult respondents with rheumatic disease experienced challenges with employment, including absenteeism, job disruptions, and productivity loss. While related to greater absenteeism, job control could play a role in a young person's ability to manage their health condition and sustain productive employment. Greater attention should also be paid to understanding health factors and social support in early work experiences. © 2015, American College of Rheumatology.

    Specimen collection is an integral component of clinical research. Specimens from subjects with various stages of cancers or other conditions, as well as those without disease, are critical tools in the hunt for biomarkers, predictors, or tests that will detect serious diseases earlier or more readily than currently possible. Analytic methodologies evolve quickly. Access to high-quality specimens, collected and handled in standardized ways that minimize potential bias or confounding factors, is key to the "bench to bedside" aim of translational research. It is essential that standard operating procedures, "the how" of creating the repositories, be defined prospectively when designing clinical trials. Small differences in the processing or handling of a specimen can have dramatic effects in analytical reliability and reproducibility, especially when multiplex methods are used. A representative working group, Standard Operating Procedures Internal Working Group (SOPIWG), comprised of members from across Early Detection Research Network (EDRN) was formed to develop standard operating procedures (SOPs) for various types of specimens collected and managed for our biomarker discovery and validation work. This report presents our consensus on SOPs for the collection, processing, handling, and storage of serum and plasma for biomarker discovery and validation.

    A growing body of research suggests that the predictive power of working memory (WM) capacity for measures of intellectual aptitude is due to the ability to control attention and select relevant information. Crucially, attentional mechanisms implicated in controlling access to WM are assumed to be domain-general, yet reports of enhanced attentional abilities in individuals with larger WM capacities are primarily within the visual domain. Here, we directly test the link between WM capacity and early attentional gating across sensory domains, hypothesizing that measures of visual WM capacity should predict an individual's capacity to allocate auditory selective attention. To address this question, auditory ERPs were recorded in a linguistic dichotic listening task, and individual differences in ERP modulations by attention were correlated with estimates of WM capacity obtained in a separate visual change detection task. Auditory selective attention enhanced ERP amplitudes at an early latency (ca. 70-90 msec), with larger P1 components elicited by linguistic probes embedded in an attended narrative. Moreover, this effect was associated with greater individual estimates of visual WM capacity. These findings support the view that domain-general attentional control mechanisms underlie the wide variation of WM capacity across individuals.

    To explore factors associated with early sex work initiation and model the independent effect of early initiation on HIV infection and prostitution arrests among adult sex workers (SWs). Baseline data (2010-2011) were drawn from a cohort of SWs who exchanged sex for money within the last month and were recruited through time location sampling in Vancouver, Canada. Analyses were restricted to adults ≥18 years old. SWs completed a questionnaire and HIV/sexually transmitted infection testing. Using multivariate logistic regression, we identified associations with early sex work initiation (<18 years old) and constructed confounder models examining the independent effect of early initiation on HIV and prostitution arrests among adult SWs. Of 508 SWs, 193 (38.0%) reported early sex work initiation, with 78.53% primarily street-involved SWs and 21.46% off-street SWs. HIV prevalence was 11.22%, which was 19.69% among early initiates. Early initiates were more likely to be Canadian born [adjusted odds ratio (AOR): 6.8, 95% confidence interval (CI): 2.42 to 19.02], inject drugs (AOR: 1.6, 95% CI: 1.0 to 2.5), and to have worked for a manager (AOR: 2.22, 95% CI: 1.3 to 3.6) or been coerced into sex work (AOR: 2.3, 95% CI: 1.14 to 4.44). Early initiation retained an independent effect on increased risk of HIV infection (AOR: 2.5, 95% CI: 1.3 to 3.2) and prostitution arrests (AOR: 2.0, 95% CI: 1.3 to 3.2). Adolescent sex work initiation is concentrated among marginalized, drug, and street-involved SWs. Early initiation holds an independent increased effect on HIV infection and criminalization of adult SWs. Findings suggest the need for evidence-based approaches to reduce harm among adult and youth SWs.

  9. Defining the public, defining sociology: hybrid science-public relations and boundary-work in early American sociology.

    PubMed

    Evans, Michael S

    2009-01-01

    In this paper, I examine how scientific disciplines define their boundaries by defining the publics with whom they engage. The case study is an episode in the development of early American sociology. In response to the dual challenge of credibility set up by the conflict between religious Baconian science and secular positivist science, key actors engaged in specific strategies of boundary-work to create their desired "sociological public"--a hybrid form of science-public relations that appealed to hostile university scientists while excluding a supportive religious audience from participation in the production of scientific knowledge. Using this case, I offer two specific insights. First I illustrate how, in the pursuit of scientific credibility, actors engage in boundary-work to differentiate audiences, not just practitioners. Such defining of publics is constitutive of scientific disciplines in their formative stage. Second, I demonstrate how audience boundaries can be redefined through the capture of existing boundary objects. Specifically, the removal of informational content in key boundary objects creates durable boundaries that are difficult to overcome.

    Patients with cancer could benefit from early primary (i.e., basic) palliative care. Scalable models of care delivery are needed. Examine the feasibility of a stepped peer navigator and social work intervention developed to improve palliative care outcomes. Single-arm prospective clinical trial. The peer navigator educated patients to advocate for pain and symptom management with their healthcare providers, motivated patients to pursue advance care planning, and discussed the role of hospice. The social worker saw patients with persistent psychosocial distress. Patients with advanced cancer at a VA Medical Center not currently in palliative care or hospice whose oncologist would not be surprised if the patient died in the subsequent year. Participation and retention rates, patient-reported symptoms and quality of life, advance directive documentation, patient satisfaction survey, and semistructured interviews. The participation rate was 38% (17/45), and 35% (7/17) completed final survey measures. Patients had stage IV (81%) and primarily genitourinary (47%) and lung (24%) malignancies. Median Eastern Cooperative Oncology Group performance status was 0. Patient-reported surveys indicated low distress (mean scores: Functional Assessment of Cancer Therapy-General, 75.3 [standard deviation {SD} 17.6]; Edmonton Symptom Assessment Scale symptom scores ranged from 1.6 to 3.8; Patient Health Questionnaire-9, 5.7 [SD 5.2]; and Generalized Anxiety Disorder-7, 2.8 [SD 4.1]). Of those who had not completed advance directives at baseline (n = 11, 65%), five completed them by the end of study (5/11, 45%). Patients who completed satisfaction surveys (n = 7) and interviews (n = 4) provided mixed reviews of the intervention. At a single site, a stepped peer navigator and social work palliative care study had several challenges to feasibility, including low patient-reported distress and loss to follow-up.

  11. Promoting occupational health interventions in early return to work by implementing financial subsidies: a Swedish case study

    PubMed Central

    2013-01-01

    Background In 2010, the Swedish government introduced a system of subsidies for occupational health (OH) service interventions, as a part in a general policy promoting early return to work. The aim of this study was to analyse the implementation of these subsidies, regarding how they were used and perceived. Methods The study was carried out using a mixed-methods approach, and comprises material from six sub-studies: a register study of the use of the subsidies, one survey to OH service providers, one survey to employers, one document analysis of the documentation from interventions, interviews with stakeholders, and case interviews with actors involved in coordinated interventions. Results The subsidized services were generally perceived as positive but were modestly used. The most extensive subsidy – for coordinated interventions – was rarely used. Employers and OH service providers reported few or no effects on services and contracts. OH service providers explained the modest use in terms of already having less bureaucratic routines in place, where applying for subsidies would involve additional costs. Information about the subsidies was primarily communicated to OH service providers, while employers were not informed. Conclusions The study highlights the complexity of promoting interventions through financial incentives, since their implementation requires that they are perceived by the stakeholders involved as purposeful, manageable and cost-effective. There are inherent political challenges in influencing stakeholders who act on a free market, in that the impact of policies may be limited, unless they are enforced by law. PMID:23566064

    2014-07-01

    Within the context of the "particularistic mobility thesis" we examine racial differences in the incidence, and determinants of, as well as timing to, mobility into management across the critical early career years at a refined level, namely, when groups share similar white collar and blue collar jobs. Findings from a Panel Study of Income Dynamics sample of men support theory and indicate that from both job levels a racial hierarchy exists: African Americans have the lowest rate of mobility, reach management through a route that is relatively formal and structured by a traditional range of stratification-based causal factors and take longest to reach management. Whites, in contrast, have the highest mobility rate, reach management through a relatively informal path that is less structured by traditional stratification-based factors, and reach management the quickest, and, across all three issues Latinos occupy an intermediate ground between African Americans and Latinos. Further, as predicted by theory, racial differences, particularly, relative to whites, are greater among those tracked from blue collar jobs than white collar jobs. Discussed are implications of the findings for understanding racial disadvantage in the American labor market across the work-career and on an inter-generational basis. Copyright © 2014 Elsevier Inc.

    Gurney, Peter

    2018-04-02

    This article contributes to a better understanding of labour anti-communism in Britain through an exploration of the evolution of ideas and attitudes within the co-operative movement during the early Cold War. It demonstrates that the period witnessed an increasingly rigid separation of co-operation from communism and argues that this separation made it harder for activists within the co-operative movement to imagine a total or utopian alternative to capitalism. Drawing particularly on a close reading of the co-operative press as well as other sources, the study is divided into three main parts. The first section discusses sympathy among co-operators for the achievements of the Soviet Union, which increased during the war against fascism. The article then moves on to consider the continuing dialogue between British co-operators and their counterparts in European communist states and how international tensions shaped co-operators' views. The final major section explores the hardening of attitude towards communism after Marshall Aid was declared in June 1947, and underlines the role played by figures such as A. V. Alexander and Jack Bailey who worked with the Information Research Department at the Foreign Office to spread anti-communism within the movement. The conclusion reflects, more speculatively, on what implications this shift may have had for the medium and long-term decline of co-operation and the hegemony of capitalist consumerism post-war.

    Child health and wellbeing is influenced by multiple factors, all of which can impact on early childhood development. Adverse early life experiences can have lasting effects across the life course, sustaining inequalities and resulting in negative consequences for the health and wellbeing of individuals and society. The potential to influence future outcomes via early intervention is widely accepted; there are numerous policy initiatives, programmes and interventions clustered around the early years theme, resulting in a broad and disparate evidence base. Existing reviews have addressed the effectiveness of early years interventions, yet there is a knowledge gap regarding the mechanisms underlying why interventions work in given contexts. This realist review seeks to address the question 'what works, for whom and in what circumstances?' in terms of early years interventions to improve child health and wellbeing. The review will be conducted following Pawson's five-stage iterative realist methodology: (1) clarify scope, (2) search for evidence, (3) appraise primary studies and extract data, (4) synthesise evidence and draw conclusions and (5) disseminate findings. The reviewers will work with stakeholders in the early stages to refine the focus of the review, create a review framework and build programme theory. Searches for primary evidence will be conducted iteratively. Data will be extracted and tested against the programme theory. A review collaboration group will oversee the review process. The review will demonstrate how early years interventions do or do not work in different contexts and with what outcomes and effects. Review findings will be written up following the RAMESES guidelines and will be disseminated via a report, presentations and peer-reviewed publications. PROSPERO CRD42015017832.

    Purpose: There has been a significant increase in the number of costly investigations of the shoulder joint over the past decade. The purposes of this study were to (1) describe the diagnostic imaging investigations ordered for injured workers seen at an Early Shoulder Physician Assessment (ESPA) program, (2) evaluate the impact of these investigations on final diagnosis and management, and (3) examine how efficient the program was by determining the appropriateness of referrals and whether costly imaging was justified. Methods: This was a retrospective review of the electronic files of injured workers who had been referred to an early assessment program because they had not progressed in their recovery or return-to-work plan within 16 weeks of the injury or reoccurrence. Results: The data of 750 consecutive patients-337 women (45%) and 413 men (55%), mean age 49 (SD 11) years-were reviewed. A total of 183 patients (24%) had been referred for further investigation. Of these, 90 (49%) were considered candidates for surgery (group 1), 58 (32%) had a change in diagnosis or management (group 2), and 17 (9%) had no change in diagnosis or management (group 3); 18 (10%) patients were lost to follow-up. We noticed a pattern in the type of diagnosis and the groups: full-thickness rotator cuff (RC) tear was the predominant diagnosis (Fisher's exact test [FET]=0.001, p <0.0001) for group 1. No statistically significant differences were found among the groups in the prevalence of labral pathology (FET=0.010, p =0.078), impingement syndrome (FET=0.012, p =0.570), partial-thickness RC tear (FET=0.004, p =0.089), or biceps pathology (FET=0.070, p =0.149). Ultrasound investigations were more prevalent in group 2 (FET=0.004, p =0.047). No pattern was found for use of magnetic resonance imaging and group allocation. However, all magnetic resonance arthrogram investigations (FET=0.007, p =0.027) had been ordered for patients who required labral or instability-related surgery

    More mothers are choosing to return to work during the first 2 years of their child's life with an uncertain impact on early developmental outcomes. To determine the association between duration of maternity leave and motor and social development of toddlers. Population-based, retrospective cohort study. The Canadian National Longitudinal Survey on Children and Youth (NLSCY) Cycle 3 provides data on the characteristics and life experience of Canadian children. For sampled households, the person most knowledgeable about the child completed a survey on demographics, parent characteristics and family environment. The analysis was limited to 6664 families with children up to 2 years. Logistic regression was used to assess the association between duration of maternity leave and impaired performance (<-1 SD below the mean) on the Motor and Social Development (MSD) scale adjusted for multiple covariates including maternal age, gender, breastfeeding and socioeconomic status. One month of maternity leave increased the odds of impaired performance on the MSD by 3% (OR 1.03, 95% CI 1.02, 1.04). This was also seen with categorized maternity leave duration. Being male (OR 1.53, 95% CI 1.35, 1.74) and having a younger mother (OR 1.48, 95% CI 0.98, 2.23) increased the risk of impaired performance on the MSD while being of higher SES reduced the risk (OR 0.96, 95% CI 0.93, 1.00). There is an association between duration of maternity leave and impaired performance in motor and social development in children up to 2 years.

    The ESO Very Large Telescope Interferometer, which allows astronomers to scrutinise objects with a precision equivalent to that of a 130-m telescope, is proving itself an unequalled success every day. One of the latest instruments installed, AMBER, has led to a flurry of scientific results, an anthology of which is being published this week as special features in the research journal Astronomy & Astrophysics. ESO PR Photo 06a/07 ESO PR Photo 06a/07 The AMBER Instrument "With its unique capabilities, the VLT Interferometer (VLTI) has created itself a niche in which it provide answers to many astronomical questions, from the shape of stars, to discs around stars, to the surroundings of the supermassive black holes in active galaxies," says Jorge Melnick (ESO), the VLT Project Scientist. The VLTI has led to 55 scientific papers already and is in fact producing more than half of the interferometric results worldwide. "With the capability of AMBER to combine up to three of the 8.2-m VLT Unit Telescopes, we can really achieve what nobody else can do," added Fabien Malbet, from the LAOG (France) and the AMBER Project Scientist. Eleven articles will appear this week in Astronomy & Astrophysics' special AMBER section. Three of them describe the unique instrument, while the other eight reveal completely new results about the early and late stages in the life of stars. ESO PR Photo 06b/07 ESO PR Photo 06b/07 The Inner Winds of Eta Carinae The first results presented in this issue cover various fields of stellar and circumstellar physics.

Other articles are devoted to the study of hot active stars of particular interest: Alpha Arae, Kappa Canis Majoris, and CPD -57o2874. They provide new, precise information about their rotating gas envelopes. An important new result concerns the enigmatic object Eta Carinae. Using AMBER with

    We aimed to investigate how early and late work shifts influenced the diurnal cortisol rhythm using a within-subjects study design. Participants were 30 healthy male non-smoking pilots, mean age 39.4, employed by a short-haul airline. The standard rotating shift pattern consisted of 5 early shifts (starting before 0600 h), followed by 3 rest days, 5 late shifts (starting after 1200 h) and 4 rest days. Pilots sampled saliva and completed subjective mood ratings in a logbook 6 times over the day on two consecutive early shift days, two late days and two rest days. Sampling was scheduled at waking, waking+30 m, waking+2.5 h, waking+8 h, waking+12 h and bedtime. Waking time, sleep duration, sleep quality and working hours were also recorded. Cortisol responses were analysed with repeated measures analysis of variance with shift condition (early, late, rest) and sample time (1-6) as within-subject factors. Early shifts were associated with a higher cortisol increase in response to awakening (CAR(i)), a greater total cortisol output over the day (AUC(G)) and a slower rate of decline over the day than late shifts or rest days. Early shifts were also associated with shorter sleep duration but co-varying for sleep duration did not alter the effects of shift on the cortisol rhythm. Both types of work shift were associated with more stress, tiredness and lower happiness than rest days, but statistical adjustment for mood ratings did not alter the findings. Early shift days were associated with significantly higher levels of circulating cortisol during waking hours than late shifts or rest days. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Background: The default mode network (DMN) is a set of brain regions typically activated at rest and suppressed during extrinsic cognition. Schizophrenia has been associated with deficient DMN suppression, though the extent to which DMN dysfunction predates psychosis onset is unclear. This study examined DMN suppression during working memory (WM) performance in youth at clinical high-risk (CHR) for psychosis, early schizophrenia (ESZ) patients, and healthy controls (HC). We hypothesized that the DMN would show load-dependent suppression during WM retrieval in HC but not in ESZ, with CHR participants showing an intermediate pattern. Methods: fMRI data were collected from CHR (n = 32), ESZ (n = 22), and HC (n = 54) participants, ages 12–30. DMN regions were defined via seed-based connectivity analysis of resting-state fMRI data from an independent HC sample. Load-dependent deactivations of these DMN regions in response to WM probes were interrogated. Results: Healthy controls showed linear load-dependent increases in DMN deactivation. Significant Group-by-Load interactions were observed in DMN regions including medial prefrontal and lateral posterior parietal cortices. Group-by-Load effects in posterior DMN nodes resulted from less suppression at higher WM loads in ESZ relative to HC, with CHR differing from neither group. In medial prefrontal cortex, suppression of activity at higher WM loads was significantly diminished in both CHR and ESZ groups, relative to HC. In addition, investigation of dorsolateral prefrontal cortex (DLPFC) activations revealed that ESZ activated right DLPFC significantly more than HC, with CHR differing from neither group. Conclusion: While HC showed WM load-dependent modulation of DMN suppression, CHR individuals had deficient higher-load DMN suppression that was similar to, but less pronounced than, the distributed suppression deficits evident in ESZ patients. These results suggest that DMN dysregulation associated with

    Early identification of persons at risk of sickness absence due to work-related stress is a crucial problem for society in general, and primary health care in particular. Tho date, no established method to do this exists. This project's aim is to evaluate whether systematic early identification of work-related stress can prevent sickness absence. This paper presents the study design, procedure and outcome measurements, as well as allocation and baseline characteristics of the study population. The study is a two-armed randomized controlled trial with follow-up at 3, 6 and 12 months. Non-sick-listed employed women and men, aged 18 to 64 years, who had mental and physical health complaints and sought care at primary health care centers (PHCC) were eligible to participate. At baseline work-related stress was measured by the Work Stress Questionnaire (WSQ), combined with feedback at consultation, at PHCC. The preventive intervention included early identification of work-related stress by the WSQ, GP training in the use of WSQ, GP feedback at consultation and finding suitable preventive measures. A process evaluation was used to explore how to facilitate future implementation and structural use of the WSQ at the PHCC. The primary outcome to compare the preventive sick leave intervention by the general practitioner (GP) versus treatment as usual is sick leave data obtained from the Swedish Social Insurance Agency register. Early screening for sick leave due to work-related stress makes it possible not only to identify those at risk for sick leave, but also to put focus on the patient's specific work-related stress problems, which can be helpful in finding suitable preventive measures. This study investigates if use of the WSQ by GPs at PHCCs, combined with feedback at consultation, prevents future sickness absence. ClinicalTrials.gov. Identifier: NCT02480855 .

    Recently, it has been suggested that pectinases could be used to hydrolyze pectin in biorefineries based on pectin-rich agro-industrial wastes. However, for this to be viable, the cost of their production would need to be lowered significantly. In fact, over the last few decades, there have been many attempts to improve pectinase production by existing strains or to screen for new strains from environmental isolates. In these studies, it is necessary to measure pectinase activities. Many researchers use single-time-point assays that involve incubation of pectinolytic extracts with pectic substrates for a fixed time, followed by determination of the liberated reducing sugars. However, different researchers use quite different conditions for this assay. Furthermore, no attention has been given to the reaction profile during the assay. In the current work, we show, for the first time, that a significant deceleration of the rate of liberation of reducing sugars occurs over the first ten minutes of the reaction. As a consequence, the incubation time used in a single-time-point assay has a large effect on the value obtained for the activity. In fact, we demonstrate that, depending on the particular combination of incubation time, pectin concentration and reaction temperature, the same extract could be reported to have activities that differ by an order of magnitude. In addition, we show that the relative activities obtained with polygalacturonic acid do not correlate with those obtained with pectin. We conclude that it is currently impossible to make meaningful comparisons between pectinase activities reported in the literature by workers who have used different assay conditions. Therefore there is an urgent need for the development of a standardized assay for evaluating the saccharification potential of pectinase complexes.

    Are you an Ebenezer Scrooge when it comes to reward and recognition for your staff? How many times last week did you phone a member of your staff, or better yet, visit in person to say that you appreciated something they did? When was the last time you wrote a note of thanks? Do you routinely recognize special efforts during staff meetings? When was the last time you awarded a certificate of appreciation to an employee for a job well done? Are employees working "behind the scenes" recognized? Do you have a system in place to recognize groups who work well as a team? If you answered "no" to most of these questions, don't fret. Establishing a reward and recognition program is relatively easy to do. And, it won't break the budget either.

    Objectives Few studies examine the influence of early predictors of work absence beyond 12 months following injury or the time-dependent relative importance of these factors. This study aimed to identify the most important sociodemographic, occupational, health, lifestyle and injury predictors of work absence at 12 and 24 months following injury and to examine changes in the relative importance of these over time. Design Prospective cohort study. Setting The Prospective Outcomes of Injury Study, New Zealand. Participants 2626 injured New Zealand workers aged 18–64 years were identified from the Prospective Outcomes of Injury Study recruited form New Zealand’s monopoly injury compensation provider injury claims register: 2092 completed the 12-month interview (80% follow-up) and 2082 completed the 24-month interview (79% follow-up). Primary and secondary outcomes measures The primary outcomes of interest was absence from work at the time of the 12-month and 24-month follow-up interviews. Results Using modified Poisson regression to estimate relative risks, important groups of workers were identified at increased risk of work absence at both 12 and 24 months: males, low-income workers, trade/manual workers, temporary employees, those reporting two or more comorbidities and those experiencing a work-related injury. Important factors unique to predicting work absence at 12 months included financial insecurity, fixed-term employment and long weekly hours worked; unique factors at 24 months included job dissatisfaction, long weekly days worked, a prior injury and sustaining an injury that was perceived to be a threat to life. Conclusions Important early predictors of work absence at 12 or 24 months following injury are multidimensional and have a time dependent pattern. A consistent set of predictors was, however, present at both time periods that are prime for early intervention. Understanding the multidimensional, time-dependent patterns of early predictors of

    The transition to retirement introduces a decline in total physical activity and an increase in TV viewing time. Nonetheless, as more time becomes available, early retirement is an ideal stage to implement health interventions. Therefore, knowledge on specific determinants of physical activity and sedentary time is needed. Former work-related physical activity has been proposed as a potential determinant, but concrete evidence is lacking. The aim of this study was to examine if former work-related sitting, standing, walking or vigorous activities predict physical activity and sedentary time during early retirement. Additionally, moderating effects of educational level and physical functioning were examined. In total, 392 recently retired Belgian adults (>6 months, <5 years) completed the International Physical Activity Questionnaire, the SF-36 Health Survey and a questionnaire on sociodemographics and former work-related activities. Generalized linear regression analyses were conducted in R. Moderating effects were examined by adding cross-products to the models. More former work-related sitting was predictive of more screen time during retirement. Lower levels of former work-related vigorous activities and higher levels of former work-related walking were associated with respectively more cycling for transport and more walking for transport during retirement. None of the predictors significantly explained passive transportation, cycling and walking for recreation, and leisure-time moderate-to-vigorous physical activity during retirement. Several moderating effects were found, but the direction of the interactions was not univocal. Former-work related behaviors are of limited importance to explain physical activity during early retirement, so future studies should focus on other individual, social and environmental determinants. Nonetheless, adults who previously had a sedentary job had higher levels of screen time during retirement, so this is an important

Nonetheless, adults who previously had a sedentary job had higher levels of screen time during

    2004-05-07

    The threat of terrorism and high-profile disease outbreaks has drawn attention to public health surveillance systems for early detection of outbreaks. State and local health departments are enhancing existing surveillance systems and developing new systems to better detect outbreaks through public health surveillance. However, information is limited about the usefulness of surveillance systems for outbreak detection or the best ways to support this function. This report supplements previous guidelines for evaluating public health surveillance systems. Use of this framework is intended to improve decision-making regarding the implementation of surveillance for outbreak detection. Use of a standardized evaluation methodology, including description of system design and operation, also will enhance the exchange of information regarding methods to improve early detection of outbreaks. The framework directs particular attention to the measurement of timeliness and validity for outbreak detection. The evaluation framework is designed to support assessment and description of all surveillance approaches to early detection, whether through traditional disease reporting, specialized analytic routines for aberration detection, or surveillance using early indicators of disease outbreaks, such as syndromic surveillance.

    2010-09-01

    The aim of this study was to assess the potential impact of staggered radiologist work shifts on the timeliness of communicating urgent imaging findings that are detected on portable overnight chest radiography of hospitalized patients. The authors conducted a retrospective study that compared the interval between the acquisition and communication of urgent findings on portable overnight critical care chest radiography detected by an early-morning shift for radiologists (3 am to 11 am) with historical experience with a standard daytime shift (8 am to 5 pm) in the detection and communication of urgent findings in a similar patient population a year earlier. During a 4-month period, 6,448 portable chest radiographic studies were interpreted on the early-morning radiologist shift. Urgent findings requiring immediate communication were detected in 308 (4.8%) studies. The early-morning shift of radiologists, on average, communicated these findings 2 hours earlier compared with the historical control group (P < .001). Staggered radiologist work shifts that include an early-morning shift can improve the timeliness of reporting urgent findings on overnight portable chest radiography of hospitalized patients.

    The attention span of K-12 students is very short; they are used to digesting information in short snippets through social media and TV. To get the students interested in physics, we created the Physics Reality Show: a series of staged short videos with duration no longer than a few minutes. Each video explains and illustrates one physics concept or law through a fast-paced sequence of physics demonstrations and experiments. The cast consists entirely of physics undergraduate students with artistic abilities and substantial experience in showing physics demonstrations at current outreach events run by the department: Physics Shows and Physics & Engineering Festival. Undergraduate students are of almost the same age as their high-school audience. They are in the best position to connect with kids and convey their fascination with physics. The PI and other faculty members who are involved in the outreach advise and coach the cast. They help students in staging the episodes and choosing the most exciting and relevant demonstrations.

    2017-02-01

    This study focuses on the analysis of the early work of Howard W. Odum (1884-1954) and the examination of the psychological aspects that marked his reflection on African American music. This analysis reveals many of the aspects that were generically shared by the psychological agenda of the period when analyzing aesthetic experience and activity. Outstanding among these are the relationship of the musical phenomenon with very basic or primary affective-emotional dimensions, the conception of the musical phenomenon as an indicator of the cognitive-affective development of human groups, its expression in the form of cultural and complex intersubjective products, or its possible participation in the technoscientific design of social reform and progress. The simultaneous treatment of all of these aspects in Odum's work brings to light the interdisciplinary framework in which early psychology moved, while revealing the theoretical and ideological contradictions and controversies that enveloped the discipline, above all, at the point where it attempted to place itself at the service of the constitution of self-governed individuals. All in all, Odum's work also reflects the crucial role that early psychology attributed to art as a privileged medium to give meaning to experience and the human being's vital purposes.

    Corbee, R J

    2013-10-01

    Obesity is an important disease with a growing incidence. Because obesity is related to several other diseases, and decreases life span, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain breeds is often suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, we investigated 1379 dogs of 128 different breeds by determining their body condition score (BCS). Overall, 18.6% of the show dogs had a BCS >5, and 1.1% of the show dogs had a BCS>7. There were significant differences between breeds, which could be correlated to the breed standards. It warrants firm discussions with breeders and judges in order to come to different interpretations of the standards to prevent overweight conditions from being the standard of beauty. © 2012 Blackwell Verlag GmbH.

    since the inception of the eighty-hour work week, work hour restrictions have incited considerable debate. Work hour policies were designed to prevent medical errors and to reduce patient morbidity and mortality. It is unclear whether work hour restrictions have been helpful in medicine in general and in orthopaedic surgery specifically. This systematic review of the literature was designed to determine the success of these restrictions in terms of patient mortality, medical errors, and complications. a systematic review of the literature was performed to determine if work hour rules have improved patient and systems-based outcomes and reduced physician errors as measured by mortality, medical errors, and complications. A random effects model was utilized to determine whether patient mortality rates were improved under the new rules. the odds of patient death before implementation of the work hour rules were 1.12 (95% confidence interval, 1.07 to 1.17) times those after implementation. These differences were consistent across disciplines. The data concerning medical or surgical complications before and after the institution of the work hour rules were mixed. There was little information in these studies concerning direct medical errors. The odds of death in nonteaching cohorts were not significantly different from that in teaching cohorts. there appears to be a decrease in mortality following the institution of work hour rules. The difference seen in teaching cohorts is not significantly different from that in nonteaching cohorts. It is unclear whether this difference would have been observed even without work hour restrictions. No study has shown a reduction in mortality for orthopaedic patients in teaching cohorts that was greater than that observed in nonteaching cohorts. Because of methodological concerns and the lack of current literature linking physician fatigue and physician underperformance with patient mortality, it is unclear whether the goals of the

    To evaluate the role of extracurricular physical activity and sedentary behavior at preschool and primary school age on working memory at primary school age and adolescence, respectively. This prospective study was based on a birth cohort across 4 Spanish regions. In the 3 younger subcohorts (n = 1093), parents reported lifestyle habits of child at age 4 years of age on a questionnaire, and children performed a computerized working memory task at 7 years of age. In the older subcohort (n = 307), the questionnaire was completed at 6 years of age and working memory was tested at 14 years of age. Adjusted regression models were developed to investigate the associations between lifestyle habits and working memory. Low extracurricular physical activity levels at 4 years of age were associated with a nonsignificant 0.95% (95% CI -2.81 to 0.92) reduction of correct responses in the working memory task at age 7 years of age. Low extracurricular physical activity levels at 6 years of age were associated with a 4.22% (95% CI -8.05 to -0.39) reduction of correct responses at age 14 years. Television watching was not associated with working memory. Other sedentary behaviors at 6 year of age were associated with a 5.07% (95% CI -9.68 to -0.46) reduction of correct responses in boys at 14 years of age. Low extracurricular physical activity levels at preschool and primary school ages were associated with poorer working memory performance at primary school age and adolescence, respectively. High sedentary behavior levels at primary school age were related negatively to working memory in adolescent boys. Copyright © 2017 Elsevier Inc. All rights reserved.

The authors don't and can't know what conversations we had, what documents we reviewed, and what protections we put in place in each televised scene. Finally, we hope to correct several misleading examples cited by the authors as well as their offhand mischaracterization of our program as a "reality" show.

  17. Maternal work early in the lives of children and its distal associations with achievement and behavior problems: a meta-analysis.

    PubMed

    Lucas-Thompson, Rachel G; Goldberg, Wendy A; Prause, JoAnn

    2010-11-01

    This meta-analysis of 69 studies (1,483 effect sizes) used random effects models to examine maternal employment during infancy/early childhood in relation to 2 major domains of child functioning: achievement and behavior problems. Analyses of studies that spanned 5 decades indicated that, with a few exceptions, early employment was not significantly associated with later achievement or internalizing/externalizing behaviors. The exceptions were for teacher ratings of achievement and internalizing behaviors: Employment was associated with higher achievement and fewer internalizing behaviors. Substantial heterogeneity among the effect sizes prompted examination of moderators. Sample-level moderator analyses pointed to the importance of socioeconomic and contextual variables, with early employment most beneficial when families were challenged by single parenthood or welfare status. Maternal employment during Years 2 and 3 was associated with higher achievement. Some moderator analyses indicated negative effects of employment for middle-class and 2-parent families and for very early employment (child's first year). Associations also differed depending on whether effect sizes were adjusted for contextual variables. Only 1 study-level moderator (sex of first author) was significant after adjusting for other moderators. The small effect size and primarily nonsignificant results for main effects of early maternal employment should allay concerns about mothers working when children are young. However, negative findings associated with employment during the child's first year are compatible with calls for more generous maternal leave policies. Results highlight the importance of social context for identifying under which conditions and for which subgroups early maternal employment is associated with positive or negative child outcomes.

    Background Psychosocial work characteristics may predict cognitive functioning after retirement. However, little research has explored specific cognitive domains associated with psychosocial work environments. Our study tested whether exposure to job demands, job control, and their combination during working life predicted post-retirement performance on eight cognitive tests. Methods We used data from French GAZEL cohort members who had undergone post-retirement cognitive testing (n=2,149). Psychosocial job characteristics were measured on average four years before retirement using Karasek’s Job Content Questionnaire (job demands, job control, demand-control combinations). We tested associations between these exposures and post-retirement performance on tests of executive function, visual-motor speed, psycho-motor speed, verbal memory, and verbal fluency using OLS regression. Results Low job control during working life was negatively associated with executive function, psychomotor speed, phonemic fluency, and semantic fluency after retirement (p’s<.05) even after adjustment for demographics, socioeconomic status, health and social behaviours, and vascular risk factors. Both passive (low-demand, low-control) and high-strain (high-demand, low-control) jobs were associated with lower scores on phonemic and semantic fluency when compared to low-strain (low-demand, high-control) jobs. Conclusions Low job control, in combination with both high and low job demands, is associated with post-retirement deficits in some, but not all, cognitive domains. In addition to work stress, associations between passive work and subsequent cognitive function may implicate lack of cognitive engagement at work as a risk factor for future cognitive difficulties.

    1994-10-01

    In the preceding article in this series last month, the author showed how to calculate the energy consumed to make a pound of product. To realize a payoff, however, the results must be presented in graphs or tables that clearly display what has happened. They must call attention to plant performance and ultimately lead to more efficient use of energy. Energy-consumption reporting is particularly valuable when viewed over a period of time. The author recommend compiling data annually and maintaining a ten-year performance history. Four cases are considered: individual plant performance; site performance for sites having more than one plant;more » company performance, for companies having more than one site; and performance based on product, for identical or similar products made at different plants or sites. Of these, individual plant performance is inherently the most useful. It also serves as the best basis for site, company and product performance reports. A key element in energy accounting is the relating of all energy consumption to a common basis. As developed last month in Part 1 in this series, the author chose Btu[sub meth] (i.e., Btu of methane equivalent, expressed as its higher heating value) for this purpose. It represents the amount of methane that would be needed to replace (in the case of fuels) or generate (in the case of steam and power) the energy being used.« less

  1. Cross-craft interactions between metal and glass working: slag additions to early Anglo-Saxon red glass

    NASA Astrophysics Data System (ADS)

    Peake, James R. N.; Freestone, Ian C.

    Opaque red glass has been extensively studied over the years, but its compositional complexity and variability means that the way in which it was manufactured is still not fully understood. Previous studies have suggested the use of metallurgical by-products in its manufacture, but until now the evidence has been limited. SEM-EDS analysis of glass beads from the early Anglo-Saxon cemetery complex at Eriswell, southeast England, has provided further insights into the production and technology of opaque red glass, which could only have been possible through invasive sampling. The matrix of the red glasses contains angular particles of slag, the main phases of which typically correspond to either fayalite (Fe2SiO4) or kirschsteinite (CaFeSiO4), orthosilicate (olivine-type) minerals characteristic of some copper- and iron-smelting slags. This material appears to have been added in part as a reducing agent, to promote the precipitation of sub-micrometer particles of the colorant phase, copper metal. Its use represents a sophisticated, if empirical, understanding of materials and can only have resulted through deliberate experimentation with metallurgical by-products by early glass workers. Slag also seems to have been added as a source of iron to colour `black' glass. The compositions of the opaque red glasses appear to be strongly paralleled by Merovingian beads from northern Europe and Anglo-Saxon beads from elsewhere in England, suggesting that this technology is likely to have been quite widespread.

    2016-05-04

    Studies have shown a negative social gradient in the incidence of early retirement. To prevent undesired early retirement, there is a need for knowledge of specific predictors in addition to social factors with a limited potential for change. The main purpose of this study was to examine musculoskeletal complaints and working conditions as predictors of early retirement among Danish female cleaners. Using Cox regression with an adjustment for extraneous factors, we compared the risk of disability pension and retirement before the nominal retirement age (65 years) in an 11-year cohort study with registry-based follow-up of 1430 female cleaners and 579 shop assistants. In subsequent analyses of female cleaners, disability pension and voluntary early retirement were modeled according to work characteristics and upper extremity complaints. The adjusted hazard rate (HR) for disability pension among cleaners compared to the control group was 2.27 (95% CI 1.58 to 3.28) and, for voluntary early retirement, 1.01 (95% CI 0.85 to 1.20). In the subset of cleaners, the predictors of disability pension were persistent shoulder pain HR: 1.98 (95% CI 1.47 to 2.67), elbow pain HR: 1.41 (95% CI 1.02 to 1.94) and symptoms of nerve entrapment of the hand HR: 1.58 (95% CI 1.14 to 2.20). Predictors of voluntary early retirement were persistent shoulder pain HR: 1.40 (95% CI 1.16 to 1.67) and floor mopping for more than 10 h per week HR: 1.20 (95% CI 1.03 to 1.40). Cleaners have a twofold higher risk of disability pension compared to the control group. Risk factors for disability pension among cleaners were persistent shoulder and elbow pain together with symptoms of nerve entrapment of the hand. The findings of specific health related predictors of early retirement could be used in secondary prevention with targeted temporary reduced workload.

    Using data from the NLSY 97, this paper investigates how work characteristics (earnings and autonomy) shape young adults’ transition to first marriage separately for men and women. The results suggest that earnings are positively associated with marriage and that this association is as strong for women as men in their mid-to-late twenties. Additionally, occupational autonomy—having the control over one’s own work structure—facilitates entry into first marriage for women in their mid-to late-20s but, for men, occupational autonomy is not associated with marriage at these ages. These results suggest that even as women’s earnings are increasingly important for marriage, other aspects of work are also important for stable family formation. PMID:27158176

    The role of gut microbiota in early life and its impact on gut health and subsequent diseases remain unclear. There is a lack of research and awareness in this area, especially in the Asia-Pacific region, including Malaysia. This paper reports the position of a Malaysian Working Group on some key issues surrounding gut microbiota in early life and its role in gut health and diseases, as well as experts' stand on probiotics and prebiotics. The group reached a consensus that certain factors, including elective caesarean; premature deliveries; complementary feeding; use of antibiotics, prebiotics and/or probiotics; and exposure to the external environmental, have an impact on gut microbiota in early life. However, as evidence is lacking, especially from the Asia-Pacific region, further studies are needed to understand how gut microbiota in early life affects subsequent diseases, including allergy, inflammatory bowel disease, obesity and infantile colic. Lastly, although beneficial in acute diarrhoeal disease and probably allergic eczema, probiotics (and/or prebiotics) should be used cautiously in other gut dysbiotic conditions until more data are available. © 2017 The Authors.

    Youth participation is central to early intervention policy and quality frameworks. There is good evidence for peer support (individuals with lived experience helping other consumers) and shared decision making (involving consumers in making decisions about their own care) in adult settings. However, youth programs are rarely tested or described in detail. This report aims to fill this gap by describing a consumer focused intervention in an early intervention service. This paper describes the development process, intervention content and implementation challenges of the Choices about Healthcare Options Informed by Client Experiences and Expectations (CHOICE) Pilot Project. This highly novel and innovative project combined both youth peer work and youth shared decision making. Eight peer workers were employed to deliver an online shared decision-making tool at a youth mental health service in New South Wales, Australia. The intervention development involved best practice principles, including international standards and elements of co-design. The implementation of the peer workforce in the service involved a number of targeted strategies designed to support this new service model. However, several implementation challenges were experienced which resulted in critical learning about how best to deliver these types of interventions. Delivering peer work and shared decision making within an early intervention service is feasible, but not without challenges. Providing adequate detail about interventions and implementation strategies fills a critical gap in the literature. Understanding optimal youth involvement strategies assists others to deliver acceptable and effective services to young people who experience mental ill health. © 2017 John Wiley & Sons Australia, Ltd.

    Introduction The aim of this study is to determine whether a workplace-based early intervention injury prevention program reduces work-related musculoskeletal compensation outcomes in poultry meat processing workers. Methods A poultry meatworks in Queensland, Australia implemented an onsite early intervention which included immediate reporting and triage, reassurance, multidisciplinary participatory consultation, workplace modifica tion and onsite physiotherapy. Secondary pre-post analyses of the meatworks' compensation data over 4 years were performed, with the intervention commencing 2 years into the study period. Outcome measures included rate of claims, costs per claim and work days absent at an individual claim level. Where possible, similar analyses were performed on data for Queensland's poultry meat processing industry (excluding the meatworks used in this study). Results At the intervention meatworks, in the post intervention period an 18 % reduction in claims per 1 million working hours (p = 0.017) was observed. Generalized linear modelling revealed a significant reduction in average costs per claim of $831 (OR 0.74; 95 % CI 0.59-0.93; p = 0.009). Median days absent was reduced by 37 % (p = 0.024). For the poultry meat processing industry over the same period, generalized linear modelling revealed no significant change in average costs per claim (OR 1.02; 95 % CI 0.76-1.36; p = 0.91). Median days absent was unchanged (p = 0.93). Conclusion The introduction of an onsite, workplace-based early intervention injury prevention program demonstrated positive effects on compensation outcomes for work-related musculoskeletal disorders in poultry meat processing workers. Prospective studies are needed to confirm the findings of the present study.

    Spondyloarthritis often affects young people, typically in their working years. The aim of our study was to investigate work productivity and its relationship with disease activity and physical functioning in Italian patients with axial spondyloarthritis (axSpA) with chronic back pain (CBP) for ≥3 months and ≤2 years, and onset  < 45 years of age. Baseline absenteeism, presenteeism, work productivity loss (assessed by the Work Productivity and Activity Impairment questionnaire (WPAI)), and disease activity (assessed by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)/Ankylosing Spondylitis Disease Activity Score (ASDAS)) and functional ability (assessed by the Bath Ankylosing Spondylitis Disease Functional Index (BASFI)) of patients with axSpA (rheumatologist's diagnosis) included in the Italian section of the Spondyloarthritis Caught Early (SPACE) cohort were collected. Multivariate linear regression analysis was used to evaluate the associations between work productivity and disease activity/physical functioning. Absenteeism in 51 patients with axSpA was low (8.3 %). A decrease in work productivity was related to an increase in disease activity. Disease activity was strongly correlated with absenteeism (p < 0.01), presenteeism (p < 0.01) and work productivity loss (p < 0.001). In addition, decreased work productivity was related to a decrease in functional ability. Physical functioning was correlated with absenteeism (p < 0.001), presenteeism (p < 0.05) and work productivity loss (p < 0.001). Impairment of work productivity was correlated with disease activity and physical functioning in Italian patients with axSpA with CBP for ≥3 months and ≤2 years, with onset <45 years of age.

    The objectives were to identify work-related stress, and to analyse whether or not work-related stress served to predict sick-leave in a population of employed women who saw a doctor due to musculoskeletal or mental disorder at primary health care centres. This prospective study was based on data collected with the Work Stress Questionnaire (WSQ) at baseline 2008 and at follow-up 2009 in the primary health care centres in western Sweden. A total of 198 women participated. High perceived stress owing to indistinct organization and conflicts at baseline increased the risk for sick-leave 8 days or longer at follow-up. The adjusted relative risk (RR) was 2.50 (1.14-5.49). The combination of high stress perception owing to indistinct organization and high stress perception owing to individual demands and commitment increased the risk for sickness absence of 8 days or longer with an adjusted RR of 4.34 (1.72-10.99). Work-related stress predicted sick-leave during the follow-up at 12 months. The WSQ seemed to be useful in identifying women at risk of future sick-leave. Thus, it can be recommended to introduce questions and questionnaires on work-related stress in primary health care settings to early identify women with the need for preventive measures in order to decrease risk for sick-leave due to work-related stress.

    Objective To assess changes in work productivity in patients who have achieved response using etanercept (ETN) 50 mg+methotrexate (MTX) (phase I) are randomised to ETN 25 mg+MTX versus MTX versus placebo (phase II) and then withdrawn from treatment (phase III). Methods Patients included in the analysis were in employment entering phase II of the PRIZE trial and had one or more follow-ups. Phase II was a 39-week, randomised and double-blind comparison of the 3 dose-reduction treatments. Phase III was a 26-week observational study where treatment was withdrawn. The Valuation of Lost Productivity was completed approximately every 13 weeks to estimate productivity impacts from a societal perspective. Results A total of 120 participants were included in our analyses. During phase II, ETN25+MTX or MTX improved paid work productivity by over 100 hours compared with placebo, amounting to a gain of €1752 or €1503, respectively. ETN25+MTX compared with placebo gains €1862 in total paid/unpaid productivity. At week 52, the 3-month paid work productivity loss was 21.8, 12.8 and 14.0 hours, respectively. The productivity loss increased at week 64 from week 52, dropped at week 76 for all treatment groups and then continued rising after week 76 for the placebo group (71.9 hours at week 91) but not for the other 2 groups (21.9 hours for ETX25+MTX and 27.6 hours for MTX). Conclusions The work productivity gain in phase I as a result of ETN50+MTX was marginally lost in the dose-reduction treatment groups, ETN25+MTX and MTX, but substantially lost in the placebo group during phase II. Trial registration number NCT00913458; Results. PMID:27486524

    Implementing Community Based Flood Early Warning System (EWS) in developing countries like Nepal is challenging. Complex topography and geology combined with a sparse network of river and rainfall gauges and little predictive meteorological capacity both nationally and regionally dramatically constrain EWS options. This paper provides a synopsis of the hydrological and meteorological conditions that led to flooding in the Karnali River, West Nepal during mid-August 2014, and analyses the effectiveness of flood EWS in the region. On August 14-15, 2014, a large, slow moving weather system deposited record breaking rainfall in the foothills of the Karnali River catchment. Precipitation depths of 200 to 500 mm were recorded over a 24-hour period, which led to rapid rise of river heights. At the Chisapani river gauge station used for the existing EWS, where the Karnali River exits the Himalaya onto the Indo-Gangetic Plain, water levels rapidly exceeded the 11 meter danger level. Between 3 to 6 am, water levels rose from 11 to 16. 1 meters, well beyond the design height of 15 meters. Analysis suggests that 2014 floods may have been a one-in-1000 year event. Starting with the onset of intense rainfall, the Chisapani gauge reader was in regular communication with downstream stakeholders and communities providing them with timely information regarding rising water level. This provided people just enough time to move to safe places with their livestock and key assets. Though households still lost substantial assets, without the EWS, floodwaters would have caught communities completely unaware and damage would almost certainly have been much worse. In particular, despite the complications associated with access to the Chisapani gauge and failure of critical communication nodes during the floods, EWS was instrumental in saving lives. This study explores both the details of the flood event and performance of the early warning system, and identifies lessons learned to help

    The purpose of this study is to evaluate automated implementations of continuous EEG monitoring-based detection of delayed cerebral ischemia based on methods used in classical retrospective studies. We studied 95 patients with either Fisher 3 or Hunt Hess 4 to 5 aneurysmal subarachnoid hemorrhage who were admitted to the Neurosciences ICU and underwent continuous EEG monitoring. We implemented several variations of two classical algorithms for automated detection of delayed cerebral ischemia based on decreases in alpha-delta ratio and relative alpha variability. Of 95 patients, 43 (45%) developed delayed cerebral ischemia. Our automated implementation of the classical alpha-delta ratio-based trending method resulted in a sensitivity and specificity (Se,Sp) of (80,27)%, compared with the values of (100,76)% reported in the classic study using similar methods in a nonautomated fashion. Our automated implementation of the classical relative alpha variability-based trending method yielded (Se,Sp) values of (65,43)%, compared with (100,46)% reported in the classic study using nonautomated analysis. Our findings suggest that improved methods to detect decreases in alpha-delta ratio and relative alpha variability are needed before an automated EEG-based early delayed cerebral ischemia detection system is ready for clinical use.

    Mentoring is increasingly recognized as a critical element in supporting successful careers in academic research in medicine and related disciplines, particularly for trainees and early career investigators from underrepresented backgrounds. Mentoring is often executed ad hoc; there are limited programs to train faculty to become more effective mentors, and the few that exist have a dearth of empirical support of their impact. In 2013, we recruited 34 faculty from across the US engaged in HIV-related clinical research to participate in a 2-day Mentoring the Mentors workshop. The workshop included didactic and interactive content focused on a range of topics, such as mentor-mentee communication, leadership styles, emotional intelligence, understanding the impact of diversity (unconscious bias, microaggressions, discrimination, tokenism) for mentees, and specific tools and techniques for effective mentoring. Pre- and post-workshop online evaluations documented high rates of satisfaction with the program and statistically significant improvements in self-appraised mentoring skills (e.g. addressing diversity in mentoring, communication with mentees, aligning mentor-mentee expectations), as assessed via a validated mentoring competency tool. This is the first mentoring training program focused on enhancing mentors' abilities to nurture investigators of diversity, filling an important gap, and evaluation results offer support for its effectiveness. Results suggest a need for refinement and expansion of the program and for more comprehensive, long-term evaluation of distal mentoring outcomes for those who participate in the program.

  3. The effects of mechanical transparency on adjustment to a complex visuomotor transformation at early and late working age.

    PubMed

    Heuer, Herbert; Hegele, Mathias

    Mechanical tools are transparent in the sense that their input-output relations can be derived from their perceptible characteristics. Modern technology creates more and more tools that lack mechanical transparency, such as in the control of the position of a cursor by means of a computer mouse or some other input device. We inquired whether an enhancement of transparency by means of presenting the shaft of a virtual sliding lever, which governed the transformation of hand position into cursor position, supports performance of aimed cursor movement and the acquisition of an internal model of the transformation in both younger and older adults. Enhanced transparency resulted in an improvement of visual closed-loop control in terms of movement time and curvature of cursor paths. The movement-time improvement was more pronounced at older working age than at younger working age, so that the enhancement of transparency can serve as a means to mitigate age-related declines in performance. Benefits for the acquisition of an internal model of the transformation and of explicit knowledge were absent. Thus, open-loop control in this task did not profit from enhanced mechanical transparency. These findings strongly suggest that environmental support of transparency of the effects of input devices on controlled systems might be a powerful tool to support older users. Enhanced transparency may also improve simulator-based training by increasing motivation, even if training benefits do not transfer to situations without enhanced transparency.

    To study prosodic perception in early-implanted children in relation to auditory discrimination, auditory working memory, and exposure to music. Word and sentence stress perception, discrimination of fundamental frequency (F0), intensity and duration, and forward digit span were measured twice over approximately 16 months. Musical activities were assessed by questionnaire. Twenty-one early-implanted and age-matched normal-hearing (NH) children (4-13 years). Children with cochlear implants (CIs) exposed to music performed better than others in stress perception and F0 discrimination. Only this subgroup of implanted children improved with age in word stress perception, intensity discrimination, and improved over time in digit span. Prosodic perception, F0 discrimination and forward digit span in implanted children exposed to music was equivalent to the NH group, but other implanted children performed more poorly. For children with CIs, word stress perception was linked to digit span and intensity discrimination: sentence stress perception was additionally linked to F0 discrimination. Prosodic perception in children with CIs is linked to auditory working memory and aspects of auditory discrimination. Engagement in music was linked to better performance across a range of measures, suggesting that music is a valuable tool in the rehabilitation of implanted children.

    The study deals with different 'moderate technology' entry-level commercial MHD power plants. Two of the reference plants are based on combustion of coal with air preheated in a high-temperature regenerative air heater separately fired with a low-BTU gas produced in a gasifier integrated with the power plant. The third reference plant design is based on the use of oxygen enriched combustion air. Performance calculations show that an overall power plant efficiency of the order of 44% can be reached with the use of oxygen enrichment.

    Work was performed to determine the feasibility of selectively detoxifying organic contaminants in sediments. The results of this research will be used to aid in the development of a scheme for whole-sediment toxicity identification evaluations (TIEs). The context in which the method will be used inherently restricts the treatments to which the sediments can be subjected: Sediments cannot be significantly altered physically or chemically and the presence and bioavailabilities of other toxicants must not be changed. The methodological problem is daunting because of the requirement that the detoxification method be relatively fast and convenient together with the stipulation that only innocuous and minimally invasive treatments be used. Some of the experiments described here dealt with degrees of decontamination (i.e., detoxification as predicted from instrumental measurements) of spiked sediments rather than with degrees of detoxification as gauged by toxicity tests (e.g., 48-h toxicity tests with amphipods). Although the larger TIE scheme itself is mostly outside the scope of this paper, theoretical aspects of bioavailability and of the desorption of organic contaminants from sediments are discussed.

    To evaluate household and work place outcomes for patients with rheumatoid arthritis (RA) who were homemakers or employed workers, respectively, and who were treated with adalimumab plus methotrexate versus methotrexate monotherapy. We also determined baseline predictors of household and work place outcomes. Data were from a health economic companion study to PREMIER, a 2-year, randomized controlled trial of methotrexate-naive patients with early RA (<3 years) who received treatment with adalimumab plus methotrexate, adalimumab, or methotrexate. Absenteeism (number of days missed or unfit to work), presenteeism (self-judgment of the effects of RA on job or household performance), and employment status were collected from self-reports at baseline and varying time points during the study. Household and work place outcomes were generally similar for homemakers and employed workers. Over 2 years, patients who received combination therapy missed approximately half as many days as patients who received methotrexate (17.4 versus 36.9 days for employed workers; 7.9 versus 18.6 days for homemakers). Presenteeism was lower (reflecting better productivity) for combination therapy than methotrexate monotherapy. The likelihood of gaining/retaining employment over 2 years was greater for combination therapy than methotrexate monotherapy (odds ratio 1.530, 95% confidence interval 1.038-2.255; P = 0.0318). Baseline radiographic progression was an independent predictor for retaining/gaining employment at 2 years. Compared with methotrexate monotherapy, combination therapy was associated with more positive work outcomes: less absenteeism, less presenteeism, and greater likelihood of gaining/retaining employment. Radiographic progression at baseline was predictive of the ability to retain or gain employment.

    Based on a 180-day school year, any student who misses 18 days or more per year--or about two days per month--is considered chronically absent. An alarming 4,328 Newark students in grades kindergarten through 3rd grade were chronically absent during the 2013-14 school year. When young students miss too much school, they will likely struggle…

    In this paper, we describe worked and pigment-stained Nautilus shell artefacts recovered from Jerimalai, Timor-Leste. Two of these artefacts come from contexts dating to between 38,000 and 42,000 cal. BP (calibrated years before present), and exhibit manufacturing traces (drilling, pressure flaking, grinding), as well as red colourant staining. Through describing more complete Nautilus shell ornaments from younger levels from this same site (>15,900, 9500, and 5000 cal. BP), we demonstrate that those dating to the initial occupation period of Jerimalai are of anthropogenic origin. The identification of such early shell working examples of pelagic shell in Island Southeast Asia not only adds to our growing understanding of the importance of marine resources to the earliest modern human communities in this region, but also indicates that a remarkably enduring shell working tradition was enacted in this area of the globe. Additionally, these artefacts provide the first material culture evidence that the inhabitants of Jerimalai were not only exploiting coastal resources for their nutritional requirements, but also incorporating these materials into their social technologies, and by extension, their social systems. In other words, we argue that the people of Jerimalai were already practicing a developed coastal adaptation by at least 42,000 cal. BP. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The history of the invention and development of the Laryngeal Mask in the East End of London during the years 1981-88 is briefly described. The concept evolved from home-made prototypes built from the Goldman Dental Mask through a complex series of one-off latex models culminating in a primitive factory-made silicone cuff in 1986. This work defined the design parameters necessary to reconcile the needs for safety, reliability and ease of insertion while at the same time exploring the limits to possible use. In early 1988 the final version was tested by the inventor who had by this time used the device in more than 7500 patients undergoing routine surgery. From this experience a number of important lessons were learned relating to safe and effective use, which are summarized in the inventor's Instruction Manual. The importance of referring to this volume before use is stressed.

    Studies of brain development suggest that the increase in risk taking observed during adolescence may be due to insufficient prefrontal executive function compared to a more rapidly developing subcortical motivation system. We examined executive function as assessed by working memory ability in a community sample of youth (n = 387, ages 10 to 12 at baseline) in three annual assessments to determine its relation to two forms of impulsivity (sensation seeking and acting without thinking) and a wide range of risk and externalizing behavior. Using structural equation modeling, we tested a model in which differential activation of the dorsal and ventral striatum produces imbalance in the function of these brain regions. For youth high in sensation seeking, both regions were predicted to develop with age. However, for youth high in the tendency to act without thinking, the ventral striatum was expected to dominate. The model predicted that working memory ability would exhibit (1) early weakness in youth high in acting without thinking but (2) growing strength in those high in sensation seeking. In addition, it predicted that (3) acting without thinking would be more strongly related to risk and externalizing behavior than sensation seeking. Finally, it predicted that (4) controlling for acting without thinking, sensation seeking would predict later increases in risky and externalizing behavior. All four of these predictions were confirmed. The results indicate that the rise in sensation seeking that occurs during adolescence is not accompanied by a deficit in executive function and therefore requires different intervention strategies from those for youth whose impulsivity is characterized by early signs of acting without thinking. © 2011 Blackwell Publishing Ltd.

    Exposure to stress during critical periods of development can have adverse effects on adult health behaviors, and genetic vulnerabilities may enhance these stress effects. We carried out an exploratory examination of psychological, physiological, and behavioral characteristics of 252 healthy young adults for the impact of early-life adversity (ELA) in relation to the G-to-A single nucleotide polymorphism (SNP), rs9296158, of the FKBP5 gene. FKBP5 is a molecular cochaperone that contributes to the functional status of the glucocorticoid receptor (GR) and to the quality of corticosteroid signaling. FKBP5 expression is upregulated by cortisol exposure during stressful episodes, with greater upregulation seen in A-allele carriers. As such, FKBP5 expression and GR function may be environmentally sensitive in A-allele carriers and therefore suitable for the study of gene-by-environment (G × E) interactions. Compared with FKBP5, GG homozygotes (N=118), A-allele carriers (N = 132) without psychiatric morbidity had progressively worse performance on the Stroop color-word task with increasing levels of ELA exposure (Genotype × ELA, F=5.14, P=0.007), indicating a G × E interaction on working memory in early adulthood. In addition, heart rate response to mental stress was diminished overall in AA/AG-allele carriers (F=5.15, P=0.024). Diminished working memory and attenuated autonomic responses to stress are both associated with risk for alcoholism and other substance use disorders. The present data suggest that FKBP5 in the GR pathway may be a point of vulnerability to ELA, as seen in this group of non-traumatized young adults. FKBP5 is accordingly a potential target for more extensive studies of the impact of ELA on health and health behaviors in adulthood.

    Special AT-rich sequence-binding protein 2 (Satb2) is a protein binding to the matrix attachment regions of DNA and important for gene regulation. Patients with SATB2 mutation usually suffer moderate to severe mental retardation. However, the mechanisms for the defects of intellectual activities in patients with SATB2 mutation are largely unclear. Here we established the heterozygous Satb2 mutant mice and Satb2 conditional knockout mice to mimic the patients with SATB2 mutation and figured out the role of Satb2 in mental activities. We found that the spatial memory and working memory were significantly damaged in the heterozygous Satb2 mutant mice, early postnatal Satb2-deficient mice (CaMKIIα-Cre + Satb2 fl/fl mice), and adult Satb2 ablation mice (Satb2 fl/fl mice injected with CaMKIIα-Cre virus). Functionally, late phase long-term potentiation (L-LTP) in these Satb2 mutant mice was greatly impaired. Morphologically, in CA1 neurons of CaMKIIα-Cre + Satb2 fl/fl mice, we found decreased spine density of the basal dendrites and less branches of apical dendrites that extended into lacunar molecular layer. Mechanistically, expression levels of immediate early genes (IEGs) including Fos, FosB, and Egr1 were significantly decreased after Satb2 deletion. And, Satb2 could regulate expression of FosB by binding to the promoter of FosB directly. In general, our study uncovers that Satb2 plays an important role in spatial memory and working memory by regulating IEGs-mediated hippocampal synaptic plasticity.

    Cognitive remediation therapy (CRT) is reported to improve neurocognitive and substance use disorder (SUD) outcomes in residential treatments. This National Institute of Drug Abuse funded pilot study reports on CRT as an augmentation to outpatient treatment for SUD. Recovering outpatient veterans were randomized into CRT + Work Therapy (n = 24) or work therapy (n = 24) with treatment-as-usual. Blind assessments of neurocognition and substance use were performed at baseline, 3 months (end of treatment), and 6-month follow-up. Baseline assessments revealed high rates of cognitive impairment with 87.5% showing significant decline from premorbid IQ on at least 1 measure (median = 3/14 measures). Adherence to treatment was excellent. Follow-up rates were 95.7% at 3 months and 87.5% at 6 months. Mixed effects models of cognitive change over time revealed significant differences favoring CRT + Work Therapy on working memory (WM) and executive function indices. Global index of cognition showed a nonsignificant trend (effect size [ES] = .37) favoring CRT + Work Therapy. SUD outcomes were excellent for both conditions. CRT + Work Therapy had a mean of 97% days of abstinence at 3 months, 94% in the 30 days prior to 6-month follow-up, and 24/26 weeks of total abstinence; differences between conditions were not significant. CRT was well accepted by outpatient veterans with SUDs and led to significant improvements in WM and executive functions beyond that of normal cognitive recovery. No difference between conditions was found for SUD outcomes, perhaps because work therapy obscured the benefits of CRT. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  20. Short-Term and Working Memory Impairments in Early-Implanted, Long-Term Cochlear Implant Users Are Independent of Audibility and Speech Production.

    To determine whether early-implanted, long-term cochlear implant (CI) users display delays in verbal short-term and working memory capacity when processes related to audibility and speech production are eliminated. Twenty-three long-term CI users and 23 normal-hearing controls each completed forward and backward digit span tasks under testing conditions that differed in presentation modality (auditory or visual) and response output (spoken recall or manual pointing). Normal-hearing controls reproduced more lists of digits than the CI users, even when the test items were presented visually and the responses were made manually via touchscreen response. Short-term and working memory delays observed in CI users are not due to greater demands from peripheral sensory processes such as audibility or from overt speech-motor planning and response output organization. Instead, CI users are less efficient at encoding and maintaining phonological representations in verbal short-term memory using phonological and linguistic strategies during memory tasks.
