We detect auto-Abs neutralizing 100-fold lower, more physiological, concentrations of IFN-alpha and/or IFN-omega (100 pg/ml; in 1:10 dilutions of plasma) in 13.6% of 3595 patients with critical COVID-19, including 21% of 374 patients >80 years, and 6.5% of 522 patients with severe COVID-19. These antibodies are also detected in 18% of the 1124 deceased patients (aged 20 days to 99 years; mean: 70 years). Moreover, another 1.3% of patients with critical COVID-19 and 0.9% of the deceased patients have auto-Abs neutralizing high concentrations of IFN-beta. We also show, in a sample of 34,159 uninfected individuals from the general population, that auto-Abs neutralizing high concentrations of IFN-alpha and/or IFN-omega are present in 0.18% of individuals between 18 and 69 years, 1.1% between 70 and 79 years, and 3.4% >80 years. Moreover, the proportion of individuals carrying auto-Abs neutralizing lower concentrations is greater in a subsample of 10,778 uninfected individuals: 1% of individuals 80 years. By contrast, auto-Abs neutralizing IFN-beta do not become more frequent with age. Auto-Abs neutralizing type I IFNs predate SARS-CoV-2 infection and sharply increase in prevalence after the age of 70 years. They account for about 20% of both critical COVID-19 cases in the over 80s and total fatal COVID-19 cases.Peer reviewe

    Stressors at work and elsewhere: a global survival approach

    No full text
    Abstract: The United Nations´ “Agenda 2030” aims, in an integrated manner, to address the entire multitude of major global risks – e.g., to end poverty and hunger, realize the human rights of all, and ensure the lasting protection of the planet and its natural resources. However, recent political changes put this bold initiative at risk. To increase the likelihood  of success, higher education institutions worldwide should teach and train today´s students – tomorrow´s decision makers – to think both critically and ethically, to learn to cope with ethical dilemmas, and to apply systems-thinking approaches to serious and complex societal problems. The Covid-19 pandemic provides just one example of a complex and serious challenge necessitating such approaches. Promoting decent work, full employment and economic growth is one of the other major challenges. And neither of them can be successfully dealt with in a piecemeal manne

    Long-term unemployment among women in Sweden

    No full text
    Vulnerability at long-term unemployment is discussed and the results of a study of the effects of job loss and long-term unemployment among Swedish women are presented. Psychological and physiological data for the unemployed were sampled repeatedly over a two year period. Some of the unemployed were subject to an intervention programme aiming at buffering for the possibly negative effects of unemployment. Health data from matched control groups of employed were gathered over the same period. The results indicate a strong negative stress reaction at the job loss period, followed by a gradual adaptation to the conditions of unemployment as measured by biochemical and physiological health indicators. However, a substantial proportion of the unemployed compared to the employed showed a lower degree of psycholigical well-being and more severe depressive reactions. Recommendations are given concerning further research approaches on long-term unemployment. Policy implications to reduce vulnerability at long-term unemployment are discussed.long-term unemployment job loss psychological stress physiological stress

    Behavioural and endocrine reactions in boys scoring high on Sennton neurotic scale viewing an exciting and partly violent movie and the importance of social support

    Psychoendocrine and behavioural effects elicited by viewing an exciting and partly violent movie were studied in 12-year-old boys (n = 42). The boys were divided into three groups. Group A (n = 13) consisted of boys scoring below the median value on the Sennton neurotic scale for vegetative anxiety symptoms. Group B (n = 13) consisted of boys scoring above the median value on the Sennton neurotic scale. None of these boys had ever visited a psychiatric treatment centre, and they all came from the same school. A third group, Group C (n = 16), consisted of boys who, at least once, had visited an out-patient clinic at a child psychiatric treatment centre for neurotic problems. These boys attended different schools in the hospital catchment area. Group C had the same mean score on the Sennton neurotic scale as did Group B. By having two groups of boys scoring both high on the Sennton neurotic scale, one of which knew the other boys and one that did not, we were able to study possible effects of social support on psychobiologic reactions in neurotic boys. The boys' reactions to the movie were assessed by: (1) self-ratings; (2) direct observations of the boys by a team of trained child psychologists; and (3) by analysis of urinary output of adrenaline, noradrenaline and cortisol. Group B rated their experience the strongest, viewing the movie, while Groups A and C rated themselves as rather unaffected by it. Group C was rated less verbally active, both during the control and the film periods, than were the other two groups. Group A was most motorically active during the film period. There were no significant differences during the control period in endocrine variables. During the film period Group C excerted significantly more noradrenaline than did Group A, and significantly more noradrenaline than did Group B. Intra-group differences in response to the movie were also assessed. Adrenaline excretion increased significantly only in Group C during the movie, compared with the control period. Furthermore, excretion of noradrenaline decreased significantly during the film period in Groups A and B. The A and B groups preferred to review scenes representing danger, while Group C preferred scenes representing security. It is suggested that psychosocial factors, e.g. novelty to the environment and lack of friends, caused the differences between Group C and the other two groups. Group C, which scored the same as Group B on Sennton neurotic scale, did not have access to social support in the form of friends during the movie. They were left alone with their anxiety, with little ability to express it in a group of unknown boys. Group B appeared to have coped in a more 'open way', expressing their emotions during the film period, possibly explaining this group's lower level of physiological arousal. The psychological vulnerability in Group C is further stressed by this group's desire to review scenes depicting security. It suggested that access to social support, here operationally defined as being together with friends, is an important intervening variable in predicting psychobiological effects of viewing exciting and violent motion pictures.
