- According to the geographic mosaic theory of coevolution (GMTC), clines of traits reflecting local co-adaptation (including resistance genes) should be common between a host and its parasite and should persist across time. To test the GMTC-assumption of persistent clinal patterns we compared the natural prevalence of two parasites on aspen Populus tremula trees: mining moths of the genus Phyllocnistis and leaf rust Melampsora spp. Damage data were collated from the Swedish National Forest Damage Inventory (2004–2006). In addition, occurrence of the parasites was scored in field conditions in two common gardens in the north and south of Sweden over five growing seasons (2004–2008), then related to biomass (stem height and diameter) and to concentrations of eleven leaf phenolics. Phyllocnistis mainly occurred in the northern garden, a distribution range which was confirmed by the countrywide inventory, although Phyllocnistis was more abundant on southern clones, providing evidence for possible local maladaptation. Melampsora occurred all over the country and in both gardens, but built up more quickly on northern clones, which suggests a centre of local clone maladaptation in the north. Stem growth also followed a clinal pattern as did the concentration of three phenolic compounds: benzoic acid, catechin and cinnamic acid. However, only benzoic acid was related to parasite presence: negatively to Phyllocnistis and positively to Melampsora and it could thus be a potential trait under selection. In conclusion, clines of Phyllocnistis were stronger and more persistent compared to Melampsora, which showed contrasting clines of varying strength. Our data thus support the assumption of the GMTC model that clines exist in the border between hot and cold spots and that they may be less persistent for parasites with an elevated gene flow, and/or for parasites which cover relatively larger hot spots surrounded by fewer cold spots.

- Purpose: Today, more patients with congenital heart disease (CHD) reach adulthood. There are conflicting findings concerning the relationship between quality of life (QoL) or health state for adults with CHD and the complexity of their CHD. The aim of the study was, firstly, to compare the reported health status and health perception of adult patients with CHD and, secondly, to investigate what variables influenced the patients' health status and health perception. Methods: Data from 1435 patients completing the EQ-5D questionnaire, which includes reported health status and health perception, were analyzed. Results: Valid EQ-5D data were reported by 1274 patients, showing overall results indicating a good health status. Problems were most frequently reported in the dimension "pain/discomfort" (31.9%) and "anxiety/depression" (29.8%). Higher occurrence of problems were reported by patients with complex disease i.e. single ventricle (p<0.001) and by female patients (p<0.0001). Symptomatic patients reported a lower health status (p<0.0001) and a lower perceived health on EQ-VAS (p<0.0001). Of the asymptomatic patients, 20.5% nevertheless reported problems in "pain/discomfort" and 22.2% in the "anxiety/depression" dimension. Conclusion: The health status of adults with CHD is influenced by symptoms, NYHA-classification, age and gender. Adults with CHD report a lower occurrence of problems in comparison to previously published results from a general population, but the importance of actively asking about the patient's experience is demonstrated by the high degree of asymptomatic patients reporting problems on EQ-5D.

Commitment to work and job satisfaction : studies of work orientations
- 2012
-
Bok (refereegranskat)abstract
- People's work orientations and attitudes to paid work are highly important for the welfare of any country. Still, little is currently known about how such attitudes are distributed among different countries, men and women, classes, occupations, age groups and so on. Even less is known about how work orientations have changed during the dramatic social transformations of economies and labour markets during recent decades. What happened, for example, to work orientations in Iceland when the country went bankrupt? The answer is quite surprising. Or, is it true that work is losing its position in people's lives in Western world? What is the relationship between people's attitudes to work and the way they actually behave on the labour market?This timely book deals with these questions - and more - presenting fresh knowledge on changes in work orientations in many countries. It is based on genuine theoretical arguments and thorough empirical studies, using both qualitative and quantitative methods. It is a great source of new knowledge on work orientations and changes in attitudes to work.

- Introduction: Exploring the care and service activities offered throughout the trajectory of dementia is an opportunity for countries to learn from each other. As part of the RightTimePlaceCare project’s general objective to develop best practice strategies this presentation describes development, content and application of a template to explore the dementia health, social care and welfare systems from early sign, diagnosis, intermediate and moderate stage and to the late stage of the disease. It also describes some of the findings with regard to the chain of care and service for people with dementia.Method: A step-wise consensus procedure was applied to identify, define and develop a template covering care and service throughout the disease trajectory. In addition the professionals involved were identified and defined as for their educational level.Results: In total 50 care and service activities compiled in seven groups were identified: 1) Screening, diagnostic procedure, treatment of dementia and complications; 2) Outpatient care facilities; 3) Care at home; 4) Institutional care; 5) Palliative care; 6) Informal caregiving and support; 7) Civic activities. The largest differences in terms of availability were found for care activities specifically for people with dementia. Non-pharmacological treatment was not commonly utilized in whilst pharmacological treatment for BPSD was common. Also education and social support to family caregivers was sparsely utilized.Conclusion: The care and service offered to people with dementia and family caregivers covers a wide range of activities. Facilities specifically for dementia varies among countries.There are more similarities among countries than differences.

- OBJECTIVESFatigue after an acquired brain injury is common, and is characterized by limited energy reserves to accomplish ordinary daily activities. A typical characteristic of mental fatigue is that the mental exhaustion becomes pronounced during sensory stimulation or when cognitive tasks are performed for extended periods without breaks. There is a drain of mental energy upon mental activity in situations in which there is an invasion of the senses with an overload of impressions, and in noisy and hectic environments. Another typical feature is a disproportionally long recovery time needed to restore the mental energy levels after being mentally exhausted. The mental fatigue is also dependent on the total activity level as well as the nature of the demands of daily activities. For many people, there is an increased risk of doing too much and becoming even more fatigued.METHODSWe have developed an application for Windows Phone for assessment of mental fatigue. The Mental Fatigue Scale is used. The MFS is a multidimensional questionnaire containing 15 questions. The questions included in the MFS are based on symptoms described following longitudinal studies of patients with TBI, brain tumours, infections or inflammations in the nervous system, vascular brain diseases, and other brain disorders. The app also includes information about mental fatigue. RESULTSThis application can help people determine the level of mental fatigue and it can also serve to provide an overall picture of the severity of the condition, and detect changes in mental fatigue over time. The scores will be added up and the results will be presented in the form of a rating scale and a diagram. People can then see their results for one week ago, one month ago or a whole year ago. Today, the most important recommendations are to adapt to the energy available by doing one thing at a time, resting regularly and not overdoing things. However, this is challenging for most people and it may take a long time, even years, to adapt to a sustainable level. It may also be difficult for the person to learn by himself/herself and it can take several years of considerable struggle, frustration, despair and depression, to find the right balance between rest and activity. This app can help people to be aware of mental fatigue. If they connect the results to daily activities, the app may also help them to be more aware about what may alleviate and what may make mental fatigue worse. CONCLUSIONSWith regular assessment of mental fatigue, this app may give feedback and support in order to achieve an enduring balance between activities and rest.The application can be downloaded without cost: http://www.windowsphone.com/en-us/store/app/mental-fatigue/87d4cb88-c9b5-4ac9-9a92-b63a5d8f4d82

- Globally, around 15 million people each year suffer a stroke. Only a small fraction of stroke patients who could benefit from thrombolytic treatment reach diagnosis and treatment in time. To increase this low figure we have developed microwave technology aiming to differentiate hemorrhagic from ischemic stroke patients. The standard method for breast cancer diagnosis today is X-ray mammography. Despite its recognized ability to detect tumors it suffers from some limitations. Neither the false positive nor the false negative detection rates are negligible. An interesting alternative being researched extensively today is microwave tomography. In our current strive to develop a clinical prototype we have found that the most suitable design consists of an antenna array placed in a full 3D pattern. During the last decade clinical studies have demonstrated the ability of microwave hyperthermia to dramatically enhance cancer patient survival. The fundamental challenge is to adequately heat deep-seated tumors while preventing surrounding healthy tissue from undesired heating and damage. We are specifically addressing the challenge to deliver power levels with spatial control, patient treatment planning, and noninvasive temperature measurements. © 2013 IEEE.

- Objective: To identify effective interventions which improve quality of care for people with dementia (PwD) living at home.Methods: MEDLINE-(via PubMed), CINAHL, PsycINFO and ISI Web of Science databases were searched. Inclusion criteria: (1) randomized controlled trials; (2) published in English-language, peer-reviewed journals between 1990 and 2012; (3) evaluated strategies to improve quality of care for PwD cared at home; and (4) participants older than 65.Results: 23 studies met inclusion criteria. All the studies aimed to improve PwD quality of care and most of them focused on PwD caregivers. Psychoeducational programs are the most frequently assessed interventions and multicomponent interventions produced the most promising results.Conclusion: Due to the great variety of interventions describing specific samples and contexts, comparison of practice effectiveness is difficult. However, cognitive rehabilitation in PwD is effective when applied at an early stage of the disease. Case managers have demonstrated to reduce PwD institutionalization and the use of other community services. The studies were limited by sample heterogeneity, short follow-up or insufficiently detailed description.Practice implications: To improve PwD homecare, health professionals should educate and support caregivers. Before specific interventional recommendations can be made, further research addressing the limitations of current studies is needed.© 2014 Elsevier Ireland Ltd.

Nuclear translocation and calpain-dependent reduction of Bcl-2 after neonatal cerebral hypoxia-ischemia

- Apoptosis-related mechanisms are important in the pathophysiology of hypoxic-ischemic injury in the neonatal brain. Caspases are the major executioners of apoptosis, but there are a number of upstream players that influence the cell death pathways. The Bcl-2 family proteins are important modulators of mitochondrial permeability, working either to promote or prevent apoptosis. In this study we focused on the anti-apoptotic Bcl-2 protein after neonatal cerebral hypoxia-ischemia (HI) in 8-day-old rats. Bcl-2 translocated to nuclei and accumulated there over the first 24h of reperfusion after HI, as judged by immunohistochemistry and immuno-electron microscopy. We also found that the total level of Bcl-2 decreased after HI in vivo and after ionophore challenge in cultured human neuroblastoma (IMR-32) cells in vitro. Furthermore, the Bcl-2 reduction was calpain-dependent, because it could be prevented by the calpain inhibitor CX295 both in vivo and in vitro, suggesting cross-talk between excitotoxic and apoptotic mechanisms.
