Beyond Parental Wealth: Grandparental Wealth and the Transition to Adulthood.

This study considers the multigenerational consequences of wealth transmission for the transition to young adulthood. Using a wider set of outcomes than has previously been considered, and by analyzing parental and grandparental wealth simultaneously, this work underscores the salience of multiple generations of wealth as a predictor for young adult well-being. Data comes from the US Panel Study of Income Dynamics on a sample of youth followed from mid-adolescence until the age of 20. Results from linear regression models indicate that parental wealth was associated with increases in the probability of college attendance and steady employment and inversely associated with the likelihood of nonmarital birth and idleness. Grandparental wealth predicted non-educational outcomes at least as well as parental wealth did and explained more variance in young adults' outcomes when parental wealth was lower. The association between parental wealth and non-educational outcomes suggest that wealth may inform young adults' broader life course by predicting outcomes other than college attendance. Grandparental wealth may serve a compensatory function for children with low parental wealth. Results suggest that persistently low wealth across multiple generations may impede the successful transition to young adulthood.

Suicide-relevant information processing in unipolar and bipolar depression: An eye-tracking study.

Suicide-relevant attentional biases are found in suicide attempters (SAs) with depression. Wenzel and Beck provide a theoretical framework that suggests suicide-related attention biases confer vulnerability to suicide. In this study, we integrated eye-tracking dynamics of suicide-related attentional biases with self-report measures to test their model. A free-viewing eye-tracking paradigm, which simultaneously presented four images with different valences (suicide-related, negative, positive, neutral), was examined in 76 SAs with unipolar or bipolar depression, 66 nonsuicidal depressive participants (ND), and 105 healthy never-depressed healthy control participants (HC). Structural equation modeling (SEM) was used for the theory testing. SA gazed more at suicide-relevant stimuli throughout the 25-s trial compared with ND. SA and ND initially detected suicide-related stimuli faster than HC. Groups did not differ on how often they initially gazed at suicide images or how fast they disengaged away from them. Eye-tracking indices of attentional biases, together with self-reported hopelessness, adequately fit an SEM consistent with Wenzel and Beck's cognitive theory of suicide-related information processing. Potentially, suicide-related attention biases could increase vulnerability to suicidal ideation and eventual suicidal behaviors. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Characteristics and related factors of family functioning in Chinese families during early pregnancy.

Introduction: Family functioning has been found to significantly impact each family member's health mentally, physically, and socially. A number of the research has focused on the impact of impaired family functioning in general, but limited studies explore family functioning in the vulnerable period, early pregnancy. Therefore, the study aimed to investigate the characteristics and related factors in Chinese females and partners during early pregnancy. Methods: The cross-sectional study enrolled 226 pregnant women and 166 partners. Assessment tools included the McMaster Family Assessment Device (FAD), Edinburgh Postnatal Depression Scale, Patient Health Questionnaire-9, Generalized Anxiety Disorder 7-Item, Social Support Rating Scale, and Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form. Correlation analysis was applied to investigate the related factors. Results: In the present study, FAD-Behavior Control (BC) was the only dysfunctional dimension and had the highest dysfunctional rates than other dimensions. Length of time living with a partner, depressive and anxious symptoms, and quality of life were all associated with the dysfunctional family functioning of BC. Conclusions: The study reinforced the important clues of family functioning during early pregnancy. Also, it provided new entry points for the general population and healthcare providers to minimize the negative impact that impaired family function might bring to a family.

Prediction of Clinical Outcomes With EEG Microstate in Patients With Major Depressive Disorder.

Background: The difficulty in timely evaluating patient response to antidepressants has brought great challenge to the treatment of major depressive disorder (MDD). Some studies found that the electroencephalogram (EEG) microstates might be a reliable marker to evaluate patient response to treatment. The present study aims to evaluate the relationship between EEG microstate parameters and MDD symptoms before and after treatment to identify predictive biological markers for patient response. Methods: Thirty drug-naïve MDD patients (20 females and 10 males) were enrolled in this study. All the patients received effective dosages of selective serotonin reuptake inhibitors, and EEG recordings were collected at baseline and 2 weeks of treatment. Brain activities during the eyes-closed state were recorded using 64-channel electroencephalography, and the patients' microstates were clustered into four maps according to their topography (labeled A, B, C, and D). The differences of EEG microstates before and after treatment were compared using paired t-test. Spearman correlation coefficients were calculated to identify the relationships between the improvement of depression and anxiety symptoms and microstate parameters. Results: The mean duration (69.67 ± 10.33 vs. 64.00 ± 7.70, p < 0.001) and occurrence (4.06 ± 0.69, vs. 3.69 ± 0.70, p = 0.002) of microstate B decreased significantly after treatment. The proportion of microstate B also decreased (27.53 ± 5.81, vs. 23.23 ± 4.61, p < 0.001), while the occurrence of microstate A increased after treatment. A significant negative correlation was found between the change of score of Hamilton Rating Scale for Anxiety and the increase of the occurrence of microstate A (r = -0.431, p < 0.05) after 2 weeks of treatment. The reduction of the duration of microstate B was found to be predictive of patient response to antidepressants after 3 months. Conclusion: This study explored the relationship between changes of EEG microstates and patient response to antidepressants. Depression symptoms might be associated with the duration of microstate B and anxiety symptoms related to the occurrence of microstate A. Therefore, the duration of microstate B and the occurrence of microstate A are potential biological markers for MDD patients' early response and further clinical outcomes.

Subfamily Anischiinae (Coleoptera: Eucnemidae) in Early Cretaceous of Northeast China.

Rheanischia new genus, type species Rheanischia brevicornis new species (Eucnemidae, Anischiinae) is described from the Lower Cretaceous of Liaoning, China. The presence of this species in early Cretaceous deposits provides new insight into the evolution of basal lignicolous Eucnemidae clades. Both Anischiinae and Palaeoxeninae species diversified in a world dominated by gymnosperms, before the main radiation of angiosperms. More than 95% of modern eucnemid larvae have a Palaeoxenus-type highly modified head structure, but contrary to the Palaeoxenus larva, they develop in angiosperm wood. Anischiinae utilize angiosperms as well, but their head capsule shows no such modifications. These facts prove that highly specialized morphological features do not offer definite proof of similar way of life in the distant past, nor should non-modified structures be taken as proof for another kind of substrate choice. Eucnemidae have invaded angiosperms with two quite different morphological adaptations. This fact may have implications for the evolution of all clicking elateroids.

State-Independent Microstructural White Matter Abnormalities in Major Depressive Disorder.

BACKGROUND: Even with continuous antidepressant treatment, residual symptoms and the risk of relapse can persist in remitted major depressive disorder (MDD) patients. Hence, having a clear recognition of the persistent abnormalities of the underlying neural substrate in MDD through a longitudinal investigation is of great importance. METHODS: A total of 127 adult medication-free MDD patients with an acute depressive episode and 118 matched healthy controls (HCs) underwent diffusion tensor imaging. Over a 6-month treatment course, 62 remitted patients underwent a second scan. Remission was defined as a 24-item Hamilton Depression Rating Scale (HAMD24) score ≤7 for at least two weeks. Diffusion tensor imaging was performed with a 3.0 T scanner. Differences in whole-brain fractional anisotropy (FA) between MDD patients and HCs were assessed by an independent t-test using gender, age, and education as covariates. RESULTS: Significant FA reductions in the left insula, left middle occipital gyrus, right thalamus, left pallidum and left precuneus were observed in current MDD (cMDD) patients compared with HCs. Moreover, significant FA reductions in the left insula were observed in remitted (rMDD) patients compared to HCs. However, no significant differences in FA values were found when comparing cMDD and rMDD patients. CONCLUSIONS: The abnormalities in the insula showed state-independent characteristics, while the abnormalities in the middle occipital gyrus, thalamus, pallidum and precuneus seemed to be state-dependent impairments in MDD patients.

The Tendency of Modified Electroconvulsive Therapy-Related Working Memory and Subjective Memory Deficits in Depression: A Prospective Follow-up Study.

OBJECTIVE: The aim of the study was to explore the tendency of modified electroconvulsive therapy (MECT)-related working memory and subjective memory deficits in depressed patients. METHODS: Sixty patients with unipolar/bipolar depression were prepared and enrolled for MECT and 56 subjects were enrolled as healthy controls (HCs). Their demographics (sex, age, body mass index, years of schooling, etc) and clinical characteristics (dosage and number of MECT, etc) were compared. Depression severity, working memory, and subjective memory were measured using the Hamilton Depression Rating Scale 17 (HAMD17), a Digit Span Backwards (DSB), and self-reported assessments, respectively. Measurements were taken at baseline, within 24 hours after each MECT session, and in every month for a 6-month follow-up period. RESULTS: (a) The patients had poorer performance than the HCs on DSB and HAMD17 at baseline, and the DSB score and HAMD17 total scores were negatively correlated. However, after the second MECT session, the patients' HAMD17 score was significantly improved compared with that at the baseline (P < 0.05), whereas the DSB score showed no significant difference compared with the HCs (P > 0.05). (b) After the first MECT session, 62% of the patients reported subjective memory deficits, which were exacerbated over the subsequent sessions and relieved with antidepressant treatment during the follow-up period. (c) The risk factors for prolonged subjective memory deficits were overweight and the maximum MECT dosage/age (dosage/age = the percentage of output part of total dosage × 100/age, unit: 1/year) ≥ 1.5/year (odds ratio [OR] = 15.36 and 7.98). CONCLUSIONS: Depressed patients showed poorer working memory than the HCs. Such memory deficit may be aggravated by MECT, although it may improve with the relief of depression. Although subjective memory deficits can occur after the first MECT session and gradually recover after the treatment, they may last for 6 months or longer. Persistent deficits may be related to being overweight and having a high MECT dosage.

Exploration of Major Cognitive Deficits in Medication-Free Patients With Major Depressive Disorder.

Background: Major depressive disorder (MDD) is associated with a wide range of cognitive deficits. However, it remains unclear whether there will be a major cognitive deficit independently caused by depression at acute episodes of MDD. Method: A comprehensive neurocognitive test battery was used to assess the executive function, processing speed, attention, and memory in 162 MDD patients and 142 healthy controls (HCs). A multivariate analysis of variance, hierarchical regression analyses and general linear regression analyses were used to explore the possible major cognitive deficits and their predictor variables. Results: MDD patients showed extensive impairment in all four cognitive domains. Impairment of executive function and processing speed were found to persist even with other cognitive domains and clinical variables being accounted for. Executive function and processing speed were further predicted by total disease duration and depression severity, respectively. Conclusions: Executive function and processing speed may be two distinct major deficits at acute episodes of MDD. Furthermore, the executive function is likely originated from the cumulative effect of disease duration and processing speed is possibly derived from the temporary effect of current depressive episode.
