Earthworms are attracting the attention of bioremediation research because of their short-term impact on pollutant fate. However, earthworm-assisted bioremediation largely depends on the earthworm sensitivity to target pollutants and its metabolic capacity to break down contaminants. The most studied species in soil bioremediation has been Eisenia fetida, which inhabits the soil surface feeding on decomposing organic residues.

Background: There is limited research examining the impact of risk and protective factors on late-life depression using large population-based datasets, particularly those examining differences among older migrants and non-migrants in Europe countries. Thus, the first aim was to analyze differences between migrants and non-migrants regarding socioeconomic status, depression, multimorbidity, healthy aging, and lifestyle behaviors. The second aim was to examine the impact of healthy aging on late-life depression in older migrants compared to their counterparts without a history of international migration in extensive and harmonized data from different population-based cohort studies.

Objective: Older adults may be at lower risk of common mental disorders than younger adults during the coronavirus disease 2019 (COVID-19) pandemic. Previous research has shown shown differences by age in psychosocial well-being during the pandemic and have highlighted the moderating effect of prepandemic mental disorders on that association. In this line, we examined the association of age with self-reported symptoms of loneliness, depression, anxiety, and posttraumatic stress, as well as potential roles of loneliness symptoms and prepandemic mental disorders on the association between age and mental disorder symptoms.

Article Synopsis
  • The study examines how pre-existing mental disorders affected anxiety and depression levels during the COVID-19 pandemic using data from interviews conducted with a sample of 1942 participants in 2020 and 2021.
  • Results show that anxiety increased in most groups except for those with mood disorders, while depressive symptoms rose primarily in individuals without mental disorders or with anxiety issues; greater resilience, improved social support, and lower stress were linked to better mental health outcomes.
  • The research highlights that pre-existing mental health conditions influence symptoms during the pandemic and identifies social support, resilience, and stress management as crucial factors for mental well-being.

Endogeic earthworms such as Aporrectodea caliginosa play an essential role in the agroecosystems because of their continuous burrowing and feeding (geophagous) activity, which causes a profound impact on soil texture, organic matter decomposition, soil carbon storage, microbial activity, soil biodiversity, and nutrient cycling. Accordingly, endogeic earthworms are being proposed as suitable candidates for the ecotoxicity assessment of polluted soils. However, terrestrial ecotoxicology has little considered the interactive effects from pollutants and environmental variables (temperature, moisture).

Background: When the first COVID-19 cases were noticed in China, many racist comments against Chinese individuals spread. As there is a huge need to better comprehend why all of these targeted comments and opinions developed specifically at the start of the outbreak, we sought to carefully examine racism and advocacy efforts on Twitter in the first quarter of 2020 (January 15 to March 3, 2020).

Objective: The first research question aimed to understand the main type of racism displayed on Twitter during the first quarter of 2020.

The COVID-19 outbreak, which was followed by home confinement, is expected to have had profound negative impact on the mental health of people. Associated factors, such as losing jobs and income, can be expected to lead to an increased risk of suffering from psychopathological problems. Therefore, this study was aimed at researching the associations of job and income loss with mental health, as well as the possible mediating role of perceived financial stress during the COVID-19 outbreak.

Background: Older adults may be particularly vulnerable to the negative effects of stress on depression. However, the impact of perceived stress on late-life depression is understudied in large community samples. Thus, the present study used data from a population-based sample of Irish older adults to examine the longitudinal association between perceived stress and late-life depression.

Introduction: There is growing concern about the effect of lockdown and social distancing on mental health. Subjective feelings related to social relationships such as detachment have shown a strong effect on mental health, whereas objective factors might have a moderating role in that association.

Objective: To investigate whether social support and living situation have a moderating effect on the association between detachment and affective disorder symptoms during the COVID-19 lockdown.

Introduction: The IMPACT study focuses on chronic low back pain (CLBP) and depression symptoms, a prevalent and complex problem that represents a challenge for health professionals. Acceptance and Commitment Therapy (ACT) and Brief Behavioural Activation Treatment for Depression (BATD) are effective treatments for patients with persistent pain and depression, respectively. The objectives of this 12 month, multicentre, randomised, controlled trial (RCT) are (i) to examine the efficacy and cost-utility of adding a group-based form of ACT or BATD to treatment-as-usual (TAU) for patients with CLBP and moderate to severe levels of depressive symptoms; (ii) identify pre-post differences in levels of some physiological variables and (iii) analyse the role of polymorphisms in the gene, psychological process measures and physiological variables as mediators or moderators of long-term clinical changes.

Background: There is limited research on the interaction of both positive and negative daily-life environments with stress-related genetic variants on psychotic experiences (PEs) and negative affect (NA) across the extended psychosis phenotype. This study examined whether the FK506 binding protein 51 (FKBP5) variability moderates the association of positive and negative experiences in the moment with PEs and NA in participants with incipient psychosis and their nonclinical counterparts.

Methods: A total of 233 nonclinical and 86 incipient psychosis participants were prompted for a 1-week period to assess their day-to-day experiences.

A common reaction experienced by family members of patients with psychosis is grief for the loss of their healthy relative. Importantly, high levels of perceived loss have been related to the manifestation of high expressed emotion (EE), which includes the negative attitudes expressed by relatives toward an ill family member. However, the mechanisms underlying the relationship between relatives' perceived loss and EE attitudes in the early stages of psychosis are still not fully understood.

Background: Gene-environment interaction (GxE) research has highlighted the importance of investigating the FK506 binding protein 51 (FKBP5) gene as a sensitivity gene. However, previous GxE studies with FKBP5 have not measured the full environmental spectrum or applied statistical tests to discern whether the GxE interaction fits better with the differential-susceptibility or diathesis-stress hypotheses. This study examined whether single nucleotide polymorphisms (SNPs) on FKBP5 gene moderate the association of positive and negative recent life events (LEs) with depressive symptoms, state-anxiety, neuroticism, and social anxiety traits.
