Identifying Types of Eco-Anxiety, Eco-Guilt, Eco-Grief, and Eco-Coping in a Climate-Sensitive Population: A Qualitative Study.

Background: Climate change is one of the greatest challenges of the 21st century and it can affect mental health either directly through the experience of environmental traumas or indirectly through the experience of emotional distress and anxiety about the future. However, it is not clear what possible subtypes of the emerging "psychoterratic" syndromes such as eco-anxiety, eco-guilt, and eco-grief exist, how much distress they may cause, and to what extent they facilitate ecofriendly behavior.

Methods: We analyzed semi-structured interviews (N = 17) focusing on the thoughts, emotions, and behaviors related to climate change by using a combination of inductive and deductive qualitative methods.

[Anxiety as an independent cardiovascular risk].

Anxiety itself, and anxiety disorders in particular, seem to represent an independent risk factor for cardiovascular diseases as important as obesity, hypertension, sendentary lifestyle or hyperlipidemia. Anxiety-related noradrenaline and HPA overactivity, excessive sympathetic nervous system activation, and the permanently elevated level of several neuropeptides and cytokines result in hypertension and arrhythmias, endothel lesions, detrimental hemodynamic changes and platelet overactivation facilitating thrombosis. Patients with severe and sustained anxiety usually have additional adverse health behaviors which further aggravate the hazards.

Dynamics of 125I-labelled horse serum albumin presentation in vivo in guinea pigs.

Low antibody production in guinea-pig sera was determined by passive hemagglutination after 125I-labelled horse serum albumin (HoSA) injection. The appearance of radiolabelled HoSA on T cells, B cells and monocytes/macrophages (Mo) of guinea pigs was detected and followed as a function of time. The radioactivity peaks appeared first on B cells and Mo, later on the T cells.
