Effect of comorbid anxiety and depression in complicated grief on perceived cognitive failures

Unveiling the impact of siren noise exposure on cognitive function and mental health among firefighters

Firefighters reside in inherently noisy environments with sirens and emergency alarms. This noise can negatively affect the performance of firefighters and further pose a safety risk. This study investigates the relationship between siren noise exposure and its mental health disorders. In doing so, the study focuses on cognitive function among firefighters, using a Bayesian network model for the first time. This case-control study involved 92 firefighters and was conducted in 2023. Participants were categorized into case and control groups based on their exposure levels to siren noise. Noise exposures were initially measured according to ISO 9612 standards. The questionnaires covered demographic information, scales of their depression, anxiety, and stress, the Buss-Perry aggression questionnaire, and the cognitive failure questionnaire. GeNIe academic software version 2.3 was employed for Bayesian network analysis. The study results indicated a strong association that heightened siren noise exposure with a 100% probability increases depression (10%), stress (14%), anxiety (13%), and aggression (16%). In addition, each variable-noise exposure, depression, stress, anxiety, and aggression was linked to cognitive failure by 8%, 28%, 8%, and 13%, respectively. The combination of variables including noise exposure, depression, anxiety, and other mental health disorders had a 57% increase in cognitive failure. The most influence values were observed between depression and cognitive failures (0.564). The results of this study demonstrated the effect of siren noise exposure and its mental health disorders on cognitive function among firefighters. The results further highlight proper implementation of measures to mitigate these effects, and further required investigation on their effectiveness.

Follicle-stimulating hormone induces depression-like phenotype by affecting synaptic function

Depression is one of the most common affective disorders in people's life. Women are susceptibility to depression during puberty, peripartum and menopause transition, when they are suffering from sex hormone fluctuation. A lot of studies have demonstrated the neuroprotective effect of estrogen on depression in women, however, the effect of FSH on depression is unclear. In this study, we investigated the role of FSH on depression in mice. Our study demonstrated that FSH induced depression-like behaviors in mice in a dose-dependent manner. This induction was associated with elevated levels of pro-inflammatory cytokines, including IL-1β, IL-6, and TNF-α in both serum and hippocampal tissues. Additionally, FSH treatment resulted in impaired synaptic plasticity and a reduction in the expression of key synaptic proteins. It is noteworthy that the depression-like behaviors, inflammatory cytokines expression and synaptic plasticity impairment induced by FSH could be alleviated by knocking down the expression of FSH receptor (FSHR) in the hippocampus of the mice. Therefore, our findings reveal that FSH may play an important role in the pathogenesis of depression and targeting FSH may be a potential therapeutic strategy for depression during hormone fluctuation in women.

The relationship between anxiety and depression in adolescent depression patients: The mediating effect of hope level and coping modes

Background

Adolescents diagnosed with depression are particularly susceptible to anxiety and depressive symptoms, this vulnerability often diminishes their future expectations and overall outlook on life. The objective of this research was to scrutinize the associated risk factors of adolescent depression and delineated the interplay between anxiety and depressive symptoms. Concurrently, it sought to ascertain the latent mediating effects of hope levels and coping strategies within this framework.

Methods

A mixed-methods research approach was employed. For the qualitative component, 18 adolescents with depression were interviewed following a semi-structured interview guide, with sessions audio-recorded. The data were subsequently transcribed and subjected to thematic content analysis. In the quantitative phase, a cross-sectional online survey was administered to 210 adolescents diagnosed with depression using Questionnaire Star, with data analysis performed using SPSS25.0 and AMOS 24.0.

Results

The qualitative analysis identified three major themes and nine categories as key risk factors influencing the onset of adolescent depression. Three major themes were generated: school factors, family factors, and other factors. Nine categories were generated: heavy academic load, strained peer, and teacher-student relationships; unstable family structures, internal familial conflicts, and high parental expectations; a strong sense of social isolation, insufficient sexual education, and prevalent suicidal ideation or attempts. A nurturing and supportive school environment significantly bolsters adolescents' sense of hope and coping abilities, while a warm and encouraging family setting effectively mitigates psychological stress. Conversely, heightened loneliness and the onset of suicidal ideation are frequently linked to diminished hope and the adoption of maladaptive coping strategies. Hence, to comprehensively understand the intricate interplay of these factors, this study concentrated on the levels of hope and coping mechanisms, investigating their potential mediating role in adolescent anxiety and depression. Quantitative analysis revealed a positive correlation between anxiety and depression (r = 0.767, p＜0.01). Additionally, it was found that hope levels and coping strategies mediated the relationship between anxiety and depressive symptoms (β = -0.24-0.84 = 0.20, p < 0.001; β = 0.19-0.51 = -0.10, p < 0.01), with the mediating influence of hope levels being more significant than that of coping strategies.

Conclusion

Enhancing hope levels and fostering positive coping strategies are instrumental in aiding adolescents with depression to alleviate their anxiety and depressive symptoms. Moreover, this study underscored the importance of focusing on adolescents' mental health and providing them with emotional support, thereby increasing their hope levels and encouraging the adoption of positive coping mechanisms to effectively address their challenges.

The relationship between psychological distress and cognitive failure among breast cancer survivors: a network analysis

Background

Psychological distress is highly prevalent and has a severe impact on the quality of life among breast cancer survivors. This type of distress is associated with cognitive failure. However, previous studies have focused solely on the total scale scores of these two concepts while ignoring the unique relationship between specific components. In the present study, we utilized network analysis to explore the relationship between psychological distress and cognitive failure in breast cancer survivors.

Methods

The network analysis approach was adopted to estimate the regularized partial correlation network in a cross-sectional sample of 409 breast cancer survivors. All participants were assessed using the Depression Anxiety Stress Scale and the Cognitive Failure Questionnaire. The Gaussian Graphical Model was employed to estimate the network, centrality indices, and edge weights, providing a description of the characteristics of the network.

Results

The results indicated that anxiety-stress and depression-stress were the strongest edges in the community of psychological distress. Distractibility-memory was the strongest edge in the community of cognitive failure. Distractibility and memory were the most central nodes, with the highest expected influence in the network. Depression and motor coordination acted as important bridge nodes with the highest bridge expected influence.

Conclusion

Distractibility and memory in cognitive failure played important roles in activating and maintaining the relationship network. Motor coordination was identified as the crucial pathway for the impact of cognitive failure on psychological distress. Interventions targeting these specific issues might be more effective in improving cognitive failure and reducing psychological distress among breast cancer survivors.

Bereavement during the COVID-19 Pandemic: Impact on Coping Strategies and Mental Health

The COVID-19 coronavirus has caused 5.4 million deaths worldwide, including over 800,000 deaths in the United States (as of December 2021). In addition to these staggering statistics, an even greater number of individuals have died from other causes during the COVID-19 pandemic. As a result, a large portion of the global population has faced bereavement during the COVID-19 pandemic and resulting quarantine. The often rapid and unexpected nature of COVID-19 deaths and the presence of pandemic-related stressors and living restrictions make it more difficult for individuals bereaved during the pandemic to implement effective strategies for coping with the loss compared to non-pandemic periods. Quarantine-related constraints (e.g., social distancing, availability of and access to resources) impede coping strategies that have been found to be adaptive after a loss, such as supportive (e.g., seeking emotional and instrumental support) and active (e.g., problem-focused and cognitive reframing) coping, and they augment avoidant strategies (e.g., substance use, denial, and isolation) that have been found to be maladaptive. Poorer mental health outcomes (including prolonged grief disorder; PGD) have been associated with less healthy coping. This article reviews research findings regarding bereavement during the COVID-19 pandemic, discusses the effects of pandemic-related stressors on bereavement coping strategies, and proposes how different types of coping during the pandemic may account for the poorer mental health outcomes described in recent reports. Interventions for promoting adaptive coping strategies and minimizing maladaptive coping strategies are also outlined.

Psychopathology in a treatment-seeking sample of homicidally bereaved individuals: Latent class analysis

BACKGROUND

Violently bereaved individuals are at increased risk of developing severe and comorbid disorders. Comorbidity may increase psychiatric symptom severity and suicide risk and decrease psychosocial functioning compared with having one disorder. We aimed to identify subgroups of individuals with similar symptom patterns, describe prevalence rates and overall levels of prolonged grief disorder (PGD), posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD) per class, and explore associations between class membership and personal and homicide related variables.

METHODS

We investigated the comorbidity of symptoms of PGD, PTSD, MDD, and GAD in a sample of 923 treatment-seeking homicidally bereaved individuals by deploying latent class analysis.

RESULTS

Three subgroups were identified: (i) a moderate distress, low depression class (12.4%), (ii) a high distress, moderate depression class (42.7%), and (iii) a high distress and high depression class (45.0%). Prevalence rates and total scores of the questionnaires followed the pattern of iii ≥ ii ≥ i (ps ≤ .001). Being female and having experienced prior life stress distinguished between all classes (ps ≤ .05).

LIMITATIONS

The data-driven analytic approach and reliance on self-reported routine outcome monitoring data limit the generalizability and validity of the study. Strengths include the large sample size and the inclusion of four measures in a treatment-seeking, violently bereaved sample.

CONCLUSIONS

Classes were most clearly distinguishable based on symptom severity, indicating high comorbidity following bereavement by homicide. This argues for an integrated treatment that targets different complaints simultaneously rather than successively.
