Abstract
Although there is renewed optimism in biomarker research in schizophrenia, there is also need for greater inclusion of historically underrepresented groups in the research. In the present study, we surveyed 599 African American, 352 American Indian/Alaska Native, and 725 NonHispanic White participants about their attitudes toward research, knowledge and attitudes about schizophrenia, and willingness to engage in biomarker testing. Attitudes toward research were examined using the standardized 7-item Research Attitudes Questionnaire (RAQ) measure. Using structural equation modeling (SEM), we tested our predictive model of the likelihood of willingness to engage in biomarker testing for schizophrenia risk. Members of historically underrepresented groups were less willing to engage in biomarker testing. Overall, attitudes toward research, particularly trust, influenced biomarker testing willingness. These findings suggest that factors influencing willingness to engage in schizophrenia biomarker testing may be modifiable by outreach engagement and education.

Abstract
INTRODUCTION Neurocognitive deficits have been proposed as endophenotypes for schizophrenia. Although neurocognitive functioning has been studied extensively in first-degree relatives of schizophrenia patients at single time points, little is known about the change or continuity in deficits across development. METHOD The longitudinal sample was composed of 86 nonpsychotic participants who had a parent with schizophrenia (n = 28), a parent with a nonschizophrenia mental disorder (n = 31) or parents without mental illness (n = 27). Executive functioning (EF) was assessed during adolescence (M = 18 years) and adulthood (M = 32 years); attention and memory were assessed at adulthood. RESULTS The schizophrenia group, as adults, showed deficits in attention and memory relative to the no mental illness group. Only on one memory task did the schizophrenia group perform more poorly than the other mental illness group. Executive functioning improved with age for all three groups on Wisconsin Card Sorting Test perseverative errors; the rate of improvement was significantly slower for the schizophrenia and the other mental illness groups, compared to the no mental illness group. Stability in EF functioning over the 16-year period, measured by intraclass correlations, was low. CONCLUSIONS Adults at familial risk for schizophrenia showed deficits in neurocognitive functioning. The similarity of performance between those whose parents had schizophrenia and those whose parents had other mental illness, in all but the measures of memory, raises the question as to whether the neurocognitive functions examined are endophenotypes of vulnerability to schizophrenia specifically. Modest stability of EF and improved performance with age may reflect cortical maturation during early adulthood.

Abstract
The SARS-CoV-2 virus has emerged as a striking 21st century pandemic. Communities across the globe have experienced significant infection rates and widespread psychosocial stress and trauma, leading to calls for increased allocation of resources for mental health screening and treatment. In addition to the burden of psychosocial stress, there is increasing evidence of direct viral neuroinvasion of the central nervous system through physical contact with the nasal mucosa. In a parallel fashion, there is a significant body of ongoing research related to the risk of in utero viral transmission and the resulting neurodevelopmental impact in the fetus. Aberrant neurodevelopment secondary to viral transmission has previously been related to the later development of psychosis, schizophrenia, and schizophrenia spectrum disorders, generating the hypothesis that this population of individuals exposed to SARS-CoV-2 may see an increased incidence in future decades. We discuss the current understanding of the possible neurotropism and vertical transmission of SARS-CoV-2, and relate this to the history of viral pandemics to better understand the relationship of viral infection, aberrant immune response and neurodevelopment, and the risk for schizophrenia disorder.

Abstract
Schizophrenia is a major psychiatric disorder with complex genetic, environmental, and psychological etiologies. Although DISC1 gene has been shown as a risk factor for schizophrenia in some reports, there is a lack of a consensus. We therefore performed separate meta-analyses aiming to assess the associations between DISC1 SNPs and schizophrenia risk. We found that SNP rs821597 is significantly associated with schizophrenia risk in terms of both allelic and genotypic distribution, while SNP rs821616 is associated with schizophrenia in terms of genotypic distribution, especially in cases above 40 years old.

Abstract
Analyzing data from a large-scale, nationally representative sample, this study examines the association between prenatal exposure to the Chinese Famine (1959-1961) and schizophrenia risk in mid-adulthood and its urban/rural-specific and gender-specific patterns. The results showed that the cohort conceived and born during the famine had a higher risk of schizophrenia in mid-adulthood than cohorts conceived and born before or after the famine. In addition, schizophrenia risk was higher for urban residents than for rural residents and higher for females than for males. Drawing on the psychiatric features of late-onset schizophrenia in mid-adulthood, we then offer some theoretical mechanisms to explain the cohort, urban/rural, and gender differences.

Abstract
BACKGROUND Several studies suggest a link between early-life infection and adult schizophrenia. Cross-sectional studies have reported: (1) increased prevalence of Epstein-Barr Virus (EBV), a member of the Herpesviridae family in schizophrenia; (2) a possible role of Herpes simplex virus in cognitive dysfunction in schizophrenia and healthy controls. We report a longitudinal serological study of early-life EBV infection, childhood IQ, and subsequent risk of psychotic experiences (PE) in adolescence. METHODS Serum antibodies to EBV (anti-VCA IgG) were measured in 530 participants from the ALSPAC cohort at age 4 years. Assessments for IQ at age 9 and PE at age 13 were attended by 401 and 366 of these individuals, respectively. Logistic regression calculated odds ratio (OR) for PE in EBV-exposed, compared with unexposed group. Mean IQ scores were compared between these groups; effect of IQ on the EBV-PE association was examined. Potential confounders included age, gender, ethnicity, social class, household crowding, and concurrent depression and anxiety. RESULTS About 25% of the sample was exposed to EBV at age 4. EBV exposure was associated with subsequent risk of definite PE in adolescence; OR 5.37 (95% CI 1.71-16.87), which remained significant after confounding adjustment. EBV-exposed individuals compared with unexposed performed worse on all IQ measures; mean difference in full-scale IQ 4.15 (95% CI 0.44-7.87); however, this was explained by socio-demographic differences. The EBV-PE association was not explained by IQ. CONCLUSIONS Early-life exposure to EBV is associated with PE in adolescence, consistent with a role of infection/immune dysfunction in the aetiology of psychosis.
