- Understanding the responses of tundra systemsto global change has global implications. Most tundraregions lack sustained environmental monitoring and oneof the only ways to document multi-decadal change is toresample historic research sites. The International PolarYear (IPY) provided a unique opportunity for such researchthrough the Back to the Future (BTF) project (IPY project#512). This article synthesizes the results from 13 paperswithin this Ambio Special Issue. Abiotic changes includeglacial recession in the Altai Mountains, Russia; increasedsnow depth and hardness, permafrost warming, andincreased growing season length in sub-arctic Sweden;drying of ponds in Greenland; increased nutrient availabilityin Alaskan tundra ponds, and warming at mostlocations studied. Biotic changes ranged from relativelyminor plant community change at two sites in Greenland tomoderate change in the Yukon, and to dramatic increasesin shrub and tree density on Herschel Island, and in subarcticSweden. The population of geese tripled at one sitein northeast Greenland where biomass in non-grazed plotsdoubled. A model parameterized using results from a BTFstudy forecasts substantial declines in all snowbeds andincreases in shrub tundra on Niwot Ridge, Colorado overthe next century. In general, results support and provideimproved capacities for validating experimental manipulation,remote sensing, and modeling studies.

- Objectives: Christmas holidays have been associated with the highest incidence of myocardial infarction (MI). We wanted to assess possible triggers of MI during Christmas. Design: A nationwide, retrospective postal survey with case-control design. All individuals suffering an MI during the Christmas holidays 2018 and 2019 in Sweden were identified through the SWEDEHEART registry and a control group matched in age and gender with chronic coronary syndrome who did not seek medical attention during Christmas were asked for participation. Subjects completed a questionnaire asking them to rate 27 potential MI-triggers as having occurred more or less than usual. Results: A total of 189 patients suffering an MI on Christmas Eve, Christmas Day, or Boxing Day, and 157 patients in the control group responded to the questionnaire, representing response rates of 66% and 62%, respectively. Patients with MI on Christmas experienced more stress (37% vs. 21%, p =.002), depression (21% vs. 11%, p =.024), and worry (26% vs. 10%, p <.001) compared to the control group. The food and sweets consumption was increased in both groups, but to a greater extent in the control group (33% vs. 50%, p =.002 and 32% vs. 43%, p =.031). There were no increases in quarrels, anger, economic worries, or reduced compliance with medication. Conclusions: Patients suffering MI on Christmas holiday experienced higher levels of stress and emotional distress compared to patients with chronic coronary syndrome, possibly contributing to the phenomenon of holiday heart attack. Understanding what factors increase the number of MI on Christmas may help reduce the excess number of MIs and cardiovascular burden.

Tidskriftsartikel (refereegranskat)abstract
- Objective:The aim of this study was to examine health-related quality of life (HRQoL), individual QoL, anxiety and depression in patients with amyotrophic lateral sclerosis (ALS) and their next of kin in relation to patients' physical function over time.Methods:35 patients and their next of kin were studied using the Short Form-36 Health Survey (SF-36), Schedule for Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW), and Hospital Anxiety and Depression Scale (HADS) and patients also by the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised and the Norris scale every fourth to sixth month, one to four times.Results:Changes were found over time in both patients and their next of kin in the SF-36 but not in the SEIQoL-DW or HADS. Patients rated worse than their next of kin in the SF-36 physical subscales and next of kin rated worse than the patients in the global QoL score in SEIQoL-DW. Health, hobbies, and total relations were important areas in the SEIQoL-DW among all participants, but some important areas also differed between the patients and their next of kin. In most important areas among the pairs, the next of kin estimated their functioning/satisfaction worse than patients estimated their functioning/satisfaction.Significance of results:There were few changes over time in the QoL among the participants. Although most of the estimates in patients and their next of kin were equal, there were also some differences. These results emphasize the importance of support for both patients and their next of kin and that support ought to be given on both individual bases and together in pairs. The SEIQoL-DW might give signposts in the care through the course of the disease about what should be focused on to increase satisfaction of the important areas of life and might help the person to find coping strategies to handle his or her life situation.

Living with ALS – Perspectives of Patients and Next of kin
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- ALS is a neurodegenerative disease without curative treatment. The knowledge of the relationship between patients and their next of kin with respect to quality of life (QoL) is deficient. The overall aim of this thesis is to describe different perspectives of QoL of patients with ALS and their next of kin, and to describe strengths and hindrances in the manageability of their daily lives. The participants were recruited from Sahlgrenska University Hospital in Gothenburg, Sweden. In the quantitative studies I–III, 35 couples participated. Fourteen patients and thirteen next of kin participated in the qualitative study (IV). Few changes were found over time in studies I and III, but in patients, there was a decreased rating in some of the physical subscales and in general health in the health-related QoL (HRQoL). The ratings in those subscales were worse in patients than in next of kin, even though next of kin also gave a decreased rating in some of the physical and mental subscales. Next of kin estimated individual QoL to be worse than patients did. No changes were found over time in anxiety, depression, or individual QoL. The ratings in discrete pairs were often similar, indicating that if one person felt bad, the other one did also. Even though the pairs gave relatively good ratings of QoL, study II showed that QoL was worse than in a subset of the general population. Study IV found a constant fluctuation between factors that facilitated and hindered the manageability for each individual person, as well as similarities and differences between patients and their next of kin. QoL was worse in our participants compared with the general population and did not change much over time. The similarities and differences between the patients and next of kin show the need to offer them physical, psychosocial, and existential support, both together and individually, to ensure the best possible QoL. The knowledge that the manageability can change from one moment to another makes it necessary to meet the individuals with a wide perspective and to support them in the situation in which they are currently living.

- Objectives - The well-being and physical function among patients with ALS and their next of kin was studied over time. Materials and methods - Thirty-five patients with ALS and their next of kin were studied with respect to physical, general and psychological well-being by the visual analogue scale (VAS) every 4-6 months. Physical function in patients was rated by the ALSFRS-R and the Norris scale. Patients and next of kin rated the well-being of themselves and their counterpart. Results - The well-being was stable and there was a relation between the well-being of patients and next of kin throughout the time studied. Next of kin rated the well-being of the patients worse than patients rated themselves, while patients rated the well-being of their next of kin at the same level as their counterpart. Conclusions - The basic state of well-being as well as the interaction between patient and next of kin seem to be factors that influence the well-being of both patients and their next of kin.

Tidskriftsartikel (refereegranskat)abstract
- Aims: Internal and external triggers affect seasonal and circadian variations of myocardial infarction (MI). We aimed to assess sex differences in the common triggers of MI. Methods and results: A nationwide, retrospective, cross-sectional postal survey study was conducted. Individuals who experienced a MI during holidays and weekdays were identified through the SWEDEHEART registry. Twenty-seven potential MI triggers were rated in regards to occurring more or less than usual during the last 24h before the MI. Three areas were covered: Activities, emotions, and food or alcohol consumption. A logistic regression model was used to identify sex differences for each trigger and odds ratios (ORs) were reported. Four hundred and fifty-one patients, of whom 317 were men, responded. The most commonly reported triggers were stress (35.3%), worry (26.2%), depression (21.1%), and insomnia (20.0%). Women reported emotional triggers including sadness [OR 3.52, 95% confidence interval (CI) 1.92-6.45], stress (OR 2.38, 95% CI 1.52-3.71), insomnia (OR 2.31, 95% CI 1.39-3.81), and upset (OR 2.69, 95% CI 1.47-4.95) to a greater extent than men. Outdoor activity was less reported by women (OR 0.35, 95% CI 0.14-0.87). No significant sex differences were found in other activities or food and alcohol consumption. Conclusion: Self-experienced stress and distress were higher among women prior to MI compared with men. Understanding sex perspectives in acute triggers may help us find preventive strategies and reduce the excess numbers of MI.
