LocTree3 prediction of localization

The prediction of protein sub-cellular localization is an important step toward elucidating protein function. For each query protein sequence, LocTree2 applies machine learning (profile kernel SVM) to predict the native sub-cellular localization in 18 classes for eukaryotes, in six for bacteria and in three for archaea. The method outputs a score that reflects the reliability of each prediction. LocTree2 has performed on par with or better than any other state-of-the-art method. Here, we report the availability of LocTree3 as a public web server. The server includes the machine learning-based LocTree2 and improves over it through the addition of homology-based inference. Assessed on sequence-unique data, LocTree3 reached an 18-state accuracy Q18 = 80 ± 3% for eukaryotes and a six-state accuracy Q6 = 89 ± 4% for bacteria. The server accepts submissions ranging from single protein sequences to entire proteomes. Response time of the unloaded server is about 90 s for a 300-residue eukaryotic protein and a few hours for an entire eukaryotic proteome not considering the generation of the alignments. For over 1000 entirely sequenced organisms, the predictions are directly available as downloads. The web server is available at http://www.rostlab.org/services/loctree3.

["Fit4You"--A Programme for Prevention and Reduction of Overweight in Apprentices in the Workplace Setting]

The effect of health promotion at the worksite for overweight adolescents is not known. This 2-year intervention study examined the effect of a multimodal programme including nutrition counselling, sport, and life-skill training on medical and psychological outcomes. The body mass index increased slightly less in the intervention group. Semistructured interviews at the end showed that participants are highly interested in health promotion at the worksite.

[Stress Management Interventions at the Workplace Improve Perceived Stress Reactivity of Men at Higher Risk]

A randomised controlled trial was conducted in a metal working plant. The primary endpoint was perceived stress reactivity (Stress Reactivity Scale, SRS). 174 participants were randomly assigned to a stress-management intervention (SMI) (IG) or a waiting control group (CG). N=174 participants (171 male) were recruited at t0, 154 (89%) were still taking part after one year (t1), 131 (76%) after 2 years. The SRS score decreased in both groups. The conducted SMI proved to be effective over both a 1- and a 2-year period.

[Health coaching as a part of integration into the job market--evaluation of a qualification concept]

OBJECTIVES

The aim of this study is to develop, implement and evaluate an education programme enabling the pedagogic staff of employment promotion agencies to integrate health promotion approaches und activities in vocational training programmes.

METHODS

The evaluation of the education programme is based on Kirkpatrick's 4 levels training evaluation model. Besides the participants' verbal end of session feedback, a standardised questionnaire was used at the end of the education programme and after 3 months practical experience. Process evaluation included the implementation level of the methods learned.

RESULTS

From a total of 71 participants, 56 completed the first and 31 the second questionnaire (return rate 79% and 44%, respectively). The participants' mean age was 42 years, 80% were female. Only 22% of them integrated health topics systematically into their daily work. A 3-day basic training followed by case conferences during practical work was developed to transfer knowledge and practical competence in person-to-person talks and group activities (so called FIT-counselling and FIT-group). For 96% of participants, their expectations regarding the education programme were met completely or predominantly. 91% indicated a rise in motivation to work as health coach. When rating the training material, 96% judged it helpful for implementation/transfer. Many participants marked the education programme as being too short and wished more time for the topic of "mental health" and exchange of experiences. The follow-up after 3 months on-the-job training revealed that 84 and 97%, respectively, found FIT-counselling and FIT-groups helpful for their daily work. In all employment promotion agencies FIT-counselling and FIT-groups were implemented.

CONCLUSION

Our results affirm the need for and prove the acceptance of education programmes enabling the pedagogic staff of job-training programmes to deliver health coaching. Periodic case conferences take into account the participants' request for more exchange of experiences, facilitate implementation and contribute to quality and sustainability. Further development of the education programme is ongoing.

[Health Promotion for Long-Term Unemployed Persons]

A controlled trial to improve perceived health in a sample of long-term unemployed persons was conducted. As primary endpoint the SF12-questionnaire was used. The intervention was tailored to the specific needs of the long-term unemployed combining individual sessions based on motivational interviewing and group sessions designed with the participation of the participants. 365 participants were enrolled in the study. 287 or, respectively, 148 unemployed persons participated at the 3-months/12-months follow-up assessments. A positive effect of the intervention in the setting of long-term unemployed persons has been shown for perceived health, mental health and changes towards more physical activity and healthier nutrition.

[Health promotion for long-term unemployed. Effects on motivation for a healthy lifestyle]

Among the long-term unemployed ill health is often a hindrance to successful reintegration in the job market. In a quasi-experimental controlled study we examined the effects of a health promotion intervention program tailored to the specific needs of the long-term unemployed combining individual sessions based on motivational interviewing and participatory group sessions including physical activity. Over a period of 3 months the participants of the intervention group (n = 179) showed more improvement compared to the control group (n = 108) in terms of motivation for lifestyle changes towards more physical activity and healthier nutrition. Participants of the intervention group developed an intention to act significantly more often (active lifestyle: odds ratio 4.44; 95% CI: 2.00-9.83; healthy nutrition: odds ratio 3.94; 95% CI: 1.55-10.00) and actually implemented a behavior change significantly more often (active lifestyle: odds ratio 2.77; 95% CI: 1.35-5.71; healthy nutrition: odds ratio 4.34; 95% CI: 1.92-9.78). In terms of smoking and alcohol consumption no significant intervention effects were detected. The results of the study show the effectiveness of the described health promotion program regarding a lifestyle change towards more healthy nutrition and more physical activity.

[Impact of demographic changes - analysis and possible implications for the example of a specialist hospital]

The ongoing demographic development creates distinctive challenges for the management of hospitals. Due to the demographic change hospitals will be more and more dependent on the work ability and performance of an aging workforce. Therefore, age-specific work design and interventions are inevitable to create a work environment that sustainably promotes health and well-being. This study reports the work conditions, health impairments (work ability, musculoskeletal complaints), and turnover intentions (intentions to leave the organisation within the previous year, intentions to leave before official retirement age) of N=210 employees working in a specialist hospital. Age-specific analyses show that correlations between working conditions, health, and turnover intention differ substantially across the age groups. From the results an exemplary approach for the analysis and management of demography-related challenges for hospital employees has been deduced. With it, this study presents a promising strategy to identify age-related work stressors and health complaints and to promote health and well-being of hospital employees in different age groups.

Heart rate variability, hemostatic and acute inflammatory blood parameters in healthy adults after short-term exposure to welding fume

The present study aimed to investigate, whether short-term experimental exposure to high levels of welding fumes would be capable of exerting acute effects in healthy subjects. Specifically, we assessed cardiovascular function in terms of heart rate variability (HRV) as well as the concentrations of inflammatory mediators and hemostatic proteins in blood as outcome measures. Twenty subjects without a history of airway and cardiovascular diseases were exposed to either control air or welding fume for 1 h on 2 separate days under standardized conditions. The median concentration of the alveolar particle fraction during welding was 3.5 mg/m(3 )(quartiles: 1.4-6.3 mg/m(3); range 1.0-25.3 mg/m(3)). Five hours later a panel of clinical assessments was performed, including HRV measurement and drawing of blood samples. There were no changes in symptom ratings or lung function after welding fume exposure. Exposures did also not differ regarding effects on time- and frequency-domain parameters of HRV. Similarly, blood leukocyte numbers, cell differentials and the blood levels of fibrinogen, C-reactive protein, antithrombin III, factor VIII, von Willebrand factor, ristocetin cofactor, sICAM-1, tumor necrosis factor alpha, interleukin 6, interleukin 8 and epithelial neutrophil activating peptide 78 were not altered by welding fume inhalation. However, there was a significant fall in the level of endothelin-1 (P < 0.01). In conclusion, the data did not indicate effects of clinical significance of a short-term high-level exposure to welding fumes on HRV or a set of blood hemostatic and acute inflammatory parameters in healthy subjects. The small but statistically significant effect on endothelin levels demonstrated that measurable effects could be elicited even in these individuals. Overall, welding fumes are not likely to exert acute cardiovascular effects in healthy individuals.
