Understanding the Effects of the COVID-19 Pandemic on Youth Psychopathology: Genotype-Environment Interplay.

ABSTRACT:

Background

Adversity has consistently been found to predict poor mental health outcomes in youth. Perhaps the most omnipresent form of adversity in the past several decades has been the coronavirus pandemic of 2020, a global health crisis linked to elevated rates of numerous forms of youth psychopathology. The ongoing nature of the pandemic renders it critical to identify the mechanisms underlying its effects on mental health.

Methods

The current study examines pandemic-related disruption across multiple domains (e.g., home life, finances) as an etiologic moderator of several common forms of youth psychopathology. Participants were 637 adolescent twin pairs from the Twin Study of Behavioral and Emotional Development in Children (TBED-C). Mothers reported on disruption experienced by the family, using the Epidemic-Pandemic Impacts Inventory.

Results

A series of biometric genotype-by-environment interaction models revealed that disruption augmented the nonshared environmental contributions to emotional distress and conduct problems but had little effect on the etiology of attention-deficit hyperactivity problems.

Conclusions

Our results indicate that identical and fraternal twin similarity in both emotional symptoms and conduct problems decreased with greater disruption, such that children in the same family became less alike, and did so regardless of their degree of genetic resemblance. Put differently, each twin sibling appeared to have their own idiosyncratic experience of pandemic-related disruptions, with downstream consequences for their mental health.

Understanding the effects of neighborhood disadvantage on youth psychopathology.

Project description:BackgroundIn 1942, Shaw and McKay reported that disadvantaged neighborhoods predict youth psychopathology (Shaw & McKay, 1942). In the decades since, dozens of papers have confirmed and extended these early results, convincingly demonstrating that disadvantaged neighborhood contexts predict elevated rates of both internalizing and externalizing disorders across childhood and adolescence. It is unclear, however, how neighborhood disadvantage increases psychopathology.MethodsOur study sought to fill this gap in the literature by examining the Area Deprivation Index (ADI), a composite measure of Census tract disadvantage, as an etiologic moderator of several common forms of psychopathology in two samples of school-aged twins from the Michigan State University Twin Registry (N = 4815 and 1030 twin pairs, respectively), the latter of which was enriched for neighborhood disadvantage.ResultsAcross both samples, genetic influences on attention-deficit hyperactivity problems were accentuated in the presence of marked disadvantage, while nonshared environmental contributions to callous-unemotional traits increased with increasing disadvantage. However, neighborhood disadvantage had little moderating effect on the etiology of depression, anxiety, or somatic symptoms.ConclusionsSuch findings suggest that, although neighborhood disadvantage does appear to serve as a general etiologic moderator of many (but not all) forms of psychopathology, this etiologic moderation is phenotype-specific.

Effects of COVID-19 Pandemic on the Outcomes of Colorectal Cancer

Project description:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been identified as the cause of the Coronavirus disease 19 (COVID-19), which was initially reported in December 2019 in China and has since rapidly spread worldwide. Since then, the COVID-19 pandemic has caused a detrimental effect of the national health care system, causing a drastic reduction of the screening programs for colorectal cancer and requiring the redistribution of the hospital resources from elective surgery to the care of patients with SARS-Cov_2 infection requiring admission.

Youth disconnection during the COVID-19 pandemic.

Project description:We estimate a model of labor market transitions to understand the surge in youth disconnection and subsequent decline in school enrollment that occurred over the course of the COVID-19 pandemic. We highlight three observations. First, the collapse in full-time work during the spring of 2020 drove the rise in disconnection; however, in addition to the large number of young people becoming disconnected from full-time employment, the transition into full-time work also became more challenging. While transitions to full-time work from full-time work fell by 14 percent, transitions from part-time work and school fell by 43 percent and 28 percent, respectively. Second, transitions from full-time work and school into disconnection remain elevated through 2021 even as the unemployment rate reached historic lows. Finally, comparing the pandemic labor market transitions to the Great Recession, school no longer works as a safe harbor for those who are already enrolled: the surge in persistence in schooling that occurred during the Great Recession is not observed during the pandemic. These compositional changes illustrate the value of measurement of the youth labor market that goes beyond the unemployment rate.

Maternal mental health mediates the effects of pandemic-related stressors on adolescent psychopathology during COVID-19.

Project description:BackgroundThis study examined whether COVID-19-related maternal mental health changes contributed to changes in adolescent psychopathology.MethodsA community sample of 226 adolescents (12 years old before COVID-19) and their mothers were asked to complete COVID-19 surveys early in the pandemic (April-May 2020, adolescents 14 years) and approximately 6 months later (November 2020-January 2021). Surveys assessed pandemic-related stressors (health, financial, social, school, environment) and mental health.ResultsLower pre-pandemic family income-to-needs ratio was associated with higher pre-pandemic maternal mental health symptoms (anxiety, depression) and adolescent internalizing and externalizing problems, and with experiencing more pandemic-related stressors. Pandemic-related stressors predicted increases in maternal mental health symptoms, but not adolescent symptoms when other variables were covaried. Higher maternal mental health symptoms predicted concurrent increases in adolescent internalizing and externalizing. Maternal mental health mediated the effects of pre-pandemic income and pandemic-related stressors on adolescent internalizing and externalizing problems.ConclusionsResults indicate that adolescent mental health is closely tied to maternal mental health during community-level stressors such as COVID-19, and that pre-existing family economic context and adolescent symptoms increase risk for elevations in symptoms of psychopathology.

Understanding COVID-19 in children and adults

Project description:Purpose: This study aims to characterize the early innate and adaptive responses induced by SARS-CoV-2 infection in children and adults over time up to 8 weeks post symptoms onset (POS). We report the gene signature of COVID-19 over the course of the disease in both age groups. The kinetic of infection was divided in 5-time intervals according to the calculated days POS: interval 1 (0-5), interval 2 (6-14), interval 3 (15-22), interval 4 (23-35), and interval 5 (36-81). Methods: RNA extraction was performed automatically via the PAXgene Blood miRNA Kit and the QIAcube instrument (Qiagen) following the manufacturer’s protocol. RNA concentration and quality were assessed by using the Qubit instrument (Invitrogen) and the Agilent 2100 Bioanalyzer, respectively. The Stranded Total RNA Ribo-Zero Plus kit from Illumina was used for the library preparation with 100 ng of total RNA as input. Library molarity and quality were assessed with the Qubit and Tapestation using a DNA High sensitivity chip (Agilent Technologies). Libraries were pooled at 2 nM for clustering and sequenced on an Illumina HiSeq 4000 sequencer for a minimum of 30 million single-end 100 reads per sample. Main results: (I) we observed an antiviral-IFN-signature and innate-cell-activation within the first 5 days post symptoms onset (POS), while genes associated with CD4 T-cell responses, plasma cells and immunoglobulin were upregulated in both age groups during the first two weeks POS, indicative of SARS-CoV-2-specific adaptive immune responses; (II) in adults, genes associated with IFN antiviral responses and activated dendritic cells were maintained during the second week of disease, and subsided only after 14 days. By contrast, those transcriptome changes subsided already after 5 days in children.

Effects of the circulating environment of COVID-19 on platelet and neutrophil behavior

Project description:Thromboinflammatory complications are well described sequalae of Coronavirus Disease 2019 (COVID-19), and there is evidence of both hyperreactive platelet and inflammatory neutrophil biology that contributes to the thromoinflammatory milieu. It has been demonstrated in other thromboinflammatory diseases that the circulating environment may affect cellular behavior, but what role this environment exerts on platelets and neutrophils in COVID-19 remains unknown. We tested the hypotheses that 1) plasma from COVID-19 patients can induce a prothrombotic platelet functional phenotype, and 2) contents released from platelets (platelet releasate) from COVID-19 patients can induce a proinflammatory neutrophil phenotype. We treated platelets with COVID-19 patient and disease control plasma and found that COVID-19 patient plasma promoted auto-aggregation, thereby reducing response to further stimulation ex-vivo. Neither disease condition increased the number of platelets adhered to a collagen and thromboplastin coated parallel plate flow chamber, but both markedly reduced platelet size. We treated healthy neutrophils with COVID-19 patient and disease control platelet releasate and found that COVID-19 patient platelet releasate increased myeloperoxidase-deoxyribonucleic acid complexes and induced changes to neutrophil gene expression. Together these results suggest aspects of the soluble environment of COVID-19 stimulate circulating platelets, and that the contents released from those platelets can elicit inflammatory neutrophil behavior independent of direct cellular contact.

A longitudinal investigation of the effects of the COVID-19 pandemic on 2SLGBTQ+ youth experiencing homelessness.

Project description:IntroductionThe objective of this study was to examine the impacts of the coronavirus 2019 (COVID-19) pandemic on various dimensions of wellbeing among 2SLGBTQ+ youth experiencing homelessness over a 12-month period during the COVID-19 pandemic.Methods2SLGBTQ+ youth (recruited using a convenience sampling method) participated in three online surveys to assess mental health (depression, anxiety, suicidality), substance and alcohol use, health care access, and violence for 12-months between 2021-2022. Quantitative data analysis included non-parametric one-sample proportion tests, paired t-test and McNemar's test. Longitudinal data collected across all three timepoints were treated as paired data and compared to baseline data using non-parametric exact multinomial tests, and if significant, followed by pairwise post-hoc exact binomial tests. For the purposes of analysis, participants were grouped according to their baseline survey based on pandemic waves and public health restrictions.Results2SLGBTQ+ youth experiencing homelessness (n = 87) reported high rates of mental health challenges, including anxiety and depression, over 12-months during the pandemic. Youth participants reported experiencing poor mental health during the early waves of the pandemic, with improvements to their mental health throughout the pandemic; however, results were not statistically significant. Likewise, participants experienced reduced access to mental health care during the early waves of the pandemic but mental health care access increased for youth throughout the pandemic.ConclusionStudy results showed high rates of mental health issues among 2SLGBTQ+ youth, but reduced access to mental health care, due to the COVID-19 pandemic. Findings highlight the need for 2SLGBTQ+ inclusive and affirming mental health care and services to address social and mental health issues that have been exacerbated by the pandemic.

Exposure to the COVID-19 pandemic environment and generosity.

Project description:We report data from an online experiment which allows us to study how generosity changed over a 6-day period during the initial explosive growth of the COVID-19 pandemic in Andalusia, Spain, while the country was under a strict lockdown. Participants (n = 969) could donate a fraction of a €100 prize to an unknown charity. Our data are particularly rich in the age distribution and we complement them with daily public information about COVID-19-related deaths, infections and hospital admissions. We find correlational evidence that donations decreased in the period under study, particularly among older individuals. Our analysis of the mechanisms behind the detected decrease in generosity suggests that expectations about others' behaviour, perceived mortality risk and (alarming) information play a key-but independent-role for behavioural adaptation. These results indicate that social behaviour is quickly adjusted in response to the pandemic environment, possibly reflecting some form of selective prosociality.
