Social isolation causes downregulation of immune and stress response genes and behavioural changes in a social insect
2021
Humans and other social mammals experience isolation from their group as stressful, triggering behavioural and physiological anomalies that reduce fitness. While social isolation has been intensely studied in social mammals, it is less clear how social insects, which evolved sociality independently, respond to isolation. Here we examined whether the typical mammalian responses to social isolation, e.g., an impaired ability to interact socially and immune suppression are also found in social insects. We studied the consequences of social isolation on behaviour and brain gene expression in the ant Temnothorax nylanderi. Following isolation, workers interacted moderately less with adult nestma…
Age, sex, mating status, but not social isolation interact to shape basal immunity in a group-living insect
2017
International audience; Immunity is a crucial but costly trait. Individuals should therefore adjust their investment into immunity to their condition and infection risks, which are often determined by their age, sex, mating status and social environment. However, whether and how these four key factors can interact to shape basal immunity remains poorly understood. Here, we tested the simultaneous effects of these factors on hemocyte concentration and phenoloxidase activity in adults of the European earwig. We found that hemocyte concentration increased with age, and that this increase was stronger in males. We also found an age-dependent increase in phenoloxidase activity in males and virgi…
Health risks and potential remedies during prolonged lockdowns for coronavirus disease 2019 (COVID-19)
2020
Abstract As coronavirus disease 2019 (COVID-19) pandemic continues, an increasing number of countries and territories are adopting restrictive measures based on physical (“social”) distancing, aimed at preventing human-to-human transmission and thereby limiting virus propagation. Nationwide lockdowns, encompassing mass quarantine under stay-at-home ordinances, have already been proven effective to contain the COVID-19 outbreak in some countries. Nevertheless, a prolonged homestay may also be associated with potential side effects, which may jeopardize people’s health and thus must be recognized and mitigated in a way without violating local ordinances. Some of the most important undesirable…
Loneliness, Social Isolation, and Cardiovascular Health
2018
Abstract Significance: Social and demographic changes have led to an increased prevalence of loneliness and social isolation in modern society. Recent Advances: Population-based studies have demonstrated that both objective social isolation and the perception of social isolation (loneliness) are correlated with a higher risk of mortality and that both are clearly risk factors for cardiovascular disease (CVD). Lonely individuals have increased peripheral vascular resistance and elevated blood pressure. Socially isolated animals develop more atherosclerosis than those housed in groups. Critical Issues: Molecular mechanisms responsible for the increased cardiovascular risk are poorly understoo…
The role of oxidative stress in cardiovascular disease caused by social isolation and loneliness
2020
Loneliness and social isolation are common sources of chronic stress in modern society. Epidemiological studies have demonstrated that loneliness and social isolation increase mortality risk as much as smoking or alcohol consumption and more than physical inactivity or obesity. Loneliness in human is associated with higher blood pressure whereas enhanced atherosclerosis is observed in animal models of social isolation. Loneliness and social isolation lead to activation of the hypothalamic-pituitary-adrenocortical (HPA) axis, enhanced sympathetic nerve activity, impaired parasympathetic function and a proinflammatory immune response. These mechanisms have been implicated in the development o…
Prevalence and sequelae of self-reported and other-reported sexual abuse in adults with intellectual disability
2018
Background Sexual victimisation is an important problem that affects millions of people around the world, especially those with some kind of disability. The aim of this study was to determine the prevalence of self-reported and documented sexual abuse in people with mild or moderate intellectual disability and to analyse the sequelae that such experiences can have on their psychosocial health. Methods The sample consisted of 360 adults (50% men and 50% women) between 18 and 55 years of age (M = 39.87; standard deviation = 10.55). Results The prevalence of sexual abuse is 6.10% when it is self-reported (9.4% in women and 2.8% in men) and 28.6% when it is reported by professionals (27.8% in w…
The leftovers. The dead in life and social disappearance.
2020
Through an analysis of the TV series The Leftovers, we delve into the concept of "social disappearance" and into how it expresses the limits between life and death. The analysis focuses on the event that drives the plot: the mass disappearance of millions of people without reason. It has three moments: (1) the reconstruction of the order that the disappearance has broken; (2) the deviation of the mourning processes from their original logic; and (3) the acceptance that in the post-disappearance world nothing will be the same as before. The text offers some suggestions for thinking about possible lives in a world that is broken and with no promise of reconstruction, a world in which "social …
Managing stress during the coronavirus disease 2019 pandemic and beyond: Reappraisal and mindset approaches
2020
The novel coronavirus disease 2019 (COVID‐19) pandemic is a global public health crisis of a scale not previously experienced in modern times (Kickbusch et al., 2020). Governmental ‘lockdown’ measures aimed at minimizing virus transmission including ‘stay at home’ orders, closure of businesses and places of congregation, and travel restrictions have had a substantive societal impact that permeates almost every facet of daily life (Gostin & Wiley, 2020; Shanafelt, Ripp, & Trockel, 2020). These widespread changes represent considerable sources of stress in the population and will have deleterious effects on mental and physical health going forward. As nations begin to emerge from ‘lockdown’, …
The Dark Side of the Web—A Risk for Children and Adolescents Challenged by Isolation during the Novel Coronavirus 2019 Pandemic
2021
In response to the global novel coronavirus disease 2019 (COVID-19) pandemic, many countries around the world adopted social isolation measures to contain the spread of the virus.1 For children and adolescents, limitations in faceto-face activities and interactions with their traditional peer groups has been a frustrating experience. After disease containment measures, which included school closures, social distancing, and home quarantine, children and adolescents faced a prolonged state of physical isolation from their peers, teachers, extended family, and community networks that affects their emotional and behavioral health.2 Parents and pediatricians are reporting signs of mental distres…
COVID-19 Confinement and Health Risk Behaviors in Spain
2021
The World Health Organization (WHO) has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors (HRBs) with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants (
