Sense of humor among the elderly: Findings using the German version of the SHS

Empirical studies on humor among the elderly are lacking. Based on the model of sense of humor by Paul McGhee, different age groups are compared (n=979) in the present study. Data suggest that playfulness and sense of humor are stable across different age groups (in a cross-sectional design) but that elderly participants were highest in positive mood. However, they also indicated that they laughed less and less easily than younger participants. Among the elderly, those who frequently (more than once a week) meet with friends and colleagues yielded higher expressions in different aspects of the sense of humor than those who meet friends and colleagues less often. Generally, humor was positively associated with personal and national well-being. However, among those participants older than 60 years of age, national well-being (i.e., satisfaction with the government, safety, or economics in the country) was negatively related to humor. Results are discussed together with a general outlook on the use of humor interventions for increasing the well-being and quality of life of elderly peopl

Automatic medical encoding with SNOMED categories

BACKGROUND: In this paper, we describe the design and preliminary evaluation of a new type of tools to speed up the encoding of episodes of care using the SNOMED CT terminology. METHODS: The proposed system can be used either as a search tool to browse the terminology or as a categorization tool to support automatic annotation of textual contents with SNOMED concepts. The general strategy is similar for both tools and is based on the fusion of two complementary retrieval strategies with thesaural resources. The first classification module uses a traditional vector-space retrieval engine which has been fine-tuned for the task, while the second classifier is based on regular variations of the term list. For evaluating the system, we use a sample of MEDLINE. SNOMED CT categories have been restricted to Medical Subject Headings (MeSH) using the SNOMED-MeSH mapping provided by the UMLS (version 2006). RESULTS: Consistent with previous investigations applied on biomedical terminologies, our results show that performances of the hybrid system are significantly improved as compared to each single module. For top returned concepts, a precision at high ranks (P0) of more than 80% is observed. In addition, a manual and qualitative evaluation on a dozen of MEDLINE abstracts suggests that SNOMED CT could represent an improvement compared to existing medical terminologies such as MeSH. CONCLUSION: Although the precision of the SNOMED categorizer seems sufficient to help professional encoders, it is concluded that clinical benchmarks as well as usability studies are needed to assess the impact of our SNOMED encoding method in real settings.

The influence of a virtual companion on amusement when watching funny films

We investigated the role of a virtual companion and trait cheerfulness on the elicitation of amusement. Ninety participants watched funny films in four conditions: either alone, with a virtual companion laughing or verbally expressing amusement at fixed time points (pre-scripted), or additionally joining the participant’s laughter (responsive companion). Amusement was assessed facially and vocally by coding Duchenne Displays and laughter vocalizations. Participants’ cheerful mood pre and post the film watching and positive experience were assessed. Results showed that high trait cheerful individuals generally experienced and expressed more amusement than low trait cheerful individuals. The presence of a virtual companion (compared to being alone) led to more laughter for individuals low in trait cheerfulness. Unexpectedly, the responsive companion did not elicit more amusement than the pre-scripted companion. The general disliking of virtual companions and gelotophobia related negatively to amusement. Amusement expressing virtual companions may be used in interventions aiming at eliciting positive responses, especially for individuals with higher thresholds for amusement.European Union Seventh Framework Programme (FP7/2007-2013) under Grant Agreement No. 27078

Mapping proteins to disease terminologies: from UniProt to MeSH

<p>Abstract</p> <p>Background</p> <p>Although the UniProt KnowledgeBase is not a medical-oriented database, it contains information on more than 2,000 human proteins involved in pathologies. However, these annotations are not standardized, which impairs the interoperability between biological and clinical resources. In order to make these data easily accessible to clinical researchers, we have developed a procedure to link diseases described in the UniProtKB/Swiss-Prot entries to the MeSH disease terminology.</p> <p>Results</p> <p>We mapped disease names extracted either from the UniProtKB/Swiss-Prot entry comment lines or from the corresponding OMIM entry to the MeSH. Different methods were assessed on a benchmark set of 200 disease names manually mapped to MeSH terms. The performance of the retained procedure in term of precision and recall was 86% and 64% respectively. Using the same procedure, more than 3,000 disease names in Swiss-Prot were mapped to MeSH with comparable efficiency.</p> <p>Conclusions</p> <p>This study is a first attempt to link proteins in UniProtKB to the medical resources. The indexing we provided will help clinicians and researchers navigate from diseases to genes and from genes to diseases in an efficient way.

Convergence and Psychometric Properties of Character Strengths Measures: The VIA-IS and the VIA-IS-R.

This study compares the German versions of the original measure of character strengths (VIA-IS) with its latest revision (VIA-IS-R) regarding reliability and convergent, discriminant, and criterion-related validity. A sample of 499 German-speaking adults (79% women, mean age: 33.3 years) provided self-reports of character strengths (VIA-IS, VIA-IS-R) and several criteria: Core virtues, thriving, and moral behaviors. Results suggested that both measures showed satisfactory internal consistency and converged well in a multitrait-multimethod analysis. Further, both measures were comparable regarding their relationships with the criteria. Overall, the results of the current study suggest that both questionnaires are reliable and valid, and that findings based on these instruments can be considered highly comparable

Fundamental limitations for quantum and nano thermodynamics

The relationship between thermodynamics and statistical physics is valid in the thermodynamic limit - when the number of particles becomes very large. Here, we study thermodynamics in the opposite regime - at both the nano scale, and when quantum effects become important. Applying results from quantum information theory we construct a theory of thermodynamics in these limits. We derive general criteria for thermodynamical state transformations, and as special cases, find two free energies: one that quantifies the deterministically extractable work from a small system in contact with a heat bath, and the other that quantifies the reverse process. We find that there are fundamental limitations on work extraction from nonequilibrium states, owing to finite size effects and quantum coherences. This implies that thermodynamical transitions are generically irreversible at this scale. As one application of these methods, we analyse the efficiency of small heat engines and find that they are irreversible during the adiabatic stages of the cycle.Comment: Final, published versio

Continuing Educational Needs and Preferences for Swiss Registered Dietitians: Lessons Learned.

Bern University of Applied Sciences (BFH) in Switzerland offers continuing educational programs for registered dietitians. In order to initialize effective changes to maximize attendance, the promotors and barriers influencing the participation of Swiss registered dietitians to continuing education classes were identified. A survey was conducted from December 2013 to January 2014 and sent to 630 registered members of the Swiss Association of Registered Dietitians (SVDE). The questionnaire was developed on the web-based software Survey Monkey® and included 37 open- and closed-ended questions. Evaluation questions were based on a four-point Likert scale and space for individual comments was ensured. Data analysis included descriptive statistics and chi-squared tests. The final sample included 202 dietitians, the majority being female (96%), between 25 and 54 years old (90%) and 45% worked in clinical settings. Almost 70% had participated in a BFH continuing education course. Respondents were overall very satisfied with parameters including course registration, organisation, content, professional competence of teachers, and practical relevance. Preferred course format were short courses (1-2 days). The lecturer’s limited practical experience, no interest to the subject matter, and no cost coverage by employer were mentioned as the main barriers for attending courses. Based on lessons learned from this evaluation, the following aspects should be considered in order to secure the attractiveness of such programs: Favouring shorter more intensive courses and having them taught by lecturers with a strong practical experience, and hence with more insightful approach. Topics should be established based on the audience’s expectations and needs, possibly through an inquiry among professional societies. In addition, overlapping fields as for example nutritional psychology, gerontology, and transdisciplinary approaches could be further included to broaden the dietitians’ perspectives and encourage a more holistic approach. Finally, the registration process and quality of teaching environment should be seamless, in order to avoid negative influences on the course.

Humour interventions for patients in palliative care-a randomized controlled trial.

PURPOSE: The effect of humour on end-of-life patients could be beneficial and is worth investigating. However, data on humour interventions for patients in palliative care are scarce. This study evaluated the effects of a humour intervention in a palliative care setting. METHODS: A two-step intervention was developed based on the humour habits programme by McGhee. Patients were assisted to remember funny episodes from their past and recognize humorous aspects of the present and encouraged to produce humour. The intervention and control group completed questionnaires on life satisfaction, cheerfulness, symptom burden, and perceived stress and if possible gave saliva samples to investigate oxytocin levels. The study was a randomized controlled monocentre study on patients treated in a palliative care ward. Participants had to be conscious and alert enough to complete data collection. Overall, 55 patients were included and randomized to the intervention or control group. RESULTS: Parameters in the control group did not change significantly. In the intervention group, seriousness, bad mood, and stress were reduced. Cheerfulness increased significantly after the intervention. However, the methodologically complex intervention setting was too exhausting for the majority of patients. CONCLUSION: Patients who were able to participate benefited from the effects of the intervention on multiple levels. For future research simple interventions, biomarkers for well-being and assessments by staff or proxies are needed to include patients with reduced cognitive and physical performance status at the end of their lives.

Personal and environmental factors associated with active commuting to school in Switzerland

Objective. To assess whether prevalence of active commuting and regular car trips to school varies across communities and language regions in Switzerland and to determine personal and environmental correlates. Methods. During the school year 2004/2005, 1345 parental questionnaires (response rate 65%) of children attending 1st, 4th and 8th grades were completed, 1031 could be linked to a GIS environmental database. A German-speaking, a French-speaking and a bilingual study area were included. Usual mode of transportation and frequency of regular car trips to school were assessed. Associations with personal and environmental factors were evaluated with multivariate regression models. Results. Seventy-eight percent of the children actively traveled to school. Twelve percent were regularly driven at least once a week by car. Major road crossings and distance were significantly related to usual mode of transportation, but not to regular car trips. Age, daycare attendance, parental safety concerns, number of cars in the household and belonging to French-speaking population were significantly associated with increased regular car trips. Conclusion. Objective predictors are main deciding factors for active commuting to school as main mode of transport whereas personal and lifestyle factors are important factors associated with frequency of car use. Not only objective but also differing cultural attitudes should be considered when promoting non-motorized travel
