Human Reproduction Open 2024Are women's reproductive factors associated with physical frailty and comprehensive frailty in middle-age and later life?
STUDY QUESTION
Are women's reproductive factors associated with physical frailty and comprehensive frailty in middle-age and later life?
SUMMARY ANSWER
Early menarche at <13 years, age at menopause <45 years, surgical menopause, experiencing miscarriage and a shorter reproductive period of <35 years were associated with increased odds of frailty, while having two or three children was related to decreased likelihood of frailty.
WHAT IS KNOWN ALREADY
Evidence has shown that women are frailer than men in all age groups and across different populations, although women have longer lifespans. Female-specific reproductive factors may be related to risk of frailty in women.
STUDY DESIGN SIZE DURATION
A population-based cross-sectional study involved 189 898 women from the UK Biobank.
PARTICIPANTS/MATERIALS SETTING METHODS
Frailty phenotype and frailty index were used to assess physical frailty and comprehensive frailty (assessed using 38 health indicators for physical and mental wellbeing), respectively. Multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% CI between reproductive factors and likelihood of physical frailty and comprehensive frailty. Restricted cubic spline models were used to test the non-linear associations between them. In addition, we examined the combined effect of categorized age at menopause and menopause hormone therapy (MHT) on frailty.
MAIN RESULTS AND THE ROLE OF CHANCE
There was a J-shape relationship between age at menarche, reproductive period, and frailty; age at menarche <13 years and >16 years, and reproductive period <35 years or >40 years were all associated with increased odds of frailty. There was a negative linear relationship between menopausal age (either natural or surgical) and odds of frailty. Surgical menopause was associated with 30% higher odds of physical frailty (1.34, 1.27-1.43) and 30% higher odds of comprehensive frailty (1.30, 1.25-1.35). Having two or three children was linked to the lowest likelihood of physical frailty (0.48, 0.38-0.59) and comprehensive frailty (0.72, 0.64-0.81). Experiencing a miscarriage increased the odds of frailty. MHT use was linked to increased odds of physical frailty in women with normal age at natural menopause (after 45 years), while no elevated likelihood was observed in women with early natural menopause taking MHT.
LIMITATIONS REASONS FOR CAUTION
The reproductive factors were self-reported and the data might be subject to recall bias. We lacked information on the types and initiation time of MHT, could not identify infertile women who later became pregnant, and the number of infertile women may be underestimated. Individuals participating in the UK Biobank are not representative of the general UK population, limiting the generalization of our findings.
WIDER IMPLICATION OF THE FINDINGS
The reproductive factors experienced by women throughout their life course can potentially predict frailty in middle and old age. Identifying these reproductive factors as potential predictors of frailty can inform healthcare providers and policymakers about the importance of considering a woman's reproductive history when assessing their risk for frailty.

OBJECTIVE
This study aimed to analyze the associations between rheumatoid arthritis (RA) and all-cause mortality and cardiovascular disease (CVD)-related mortality using data from the National Health and Nutrition Examination Survey (NHANES) and examine the potential mediating role of depression in these correlations.
METHODS
19,165 participants across five NHANES cycles from 2007 to 2016 participated in this study. Multifactorial Cox regression models between RA, depression and two mortality outcomes and multifactorial regression models between RA and depression were constructed to examine their associations. The mediating role of depression has also been investigated.
RESULTS
The prevalence of RA in this study was 6.57 %, the all-cause mortality of RA patients was 20.57 %, and the CVD-related mortality was 6.12 %. In the fully adjusted model, RA was associated with all-cause mortality [hazard ratio (HR) = 1.28, 95 % confidence interval (CI) = 1.12 to 1.48] and CVD-related mortality (HR = 1.33, 95 % CI = 1.03 to 1.72), without detectable interaction among subgroups (P for interaction >0.05). RA also had a positive correlation with depression. Depression score demonstrated pronounced mediating effects in the connections between RA and two types of mortality, with mediation ratios of 18.2 % and 18.9 %.
LIMITATIONS
The diagnosis of RA is self-reported and may be subject to recall bias.
CONCLUSIONS
RA was positively correlated with the risk of all-cause mortality and CVD-related mortality. Depression partially mediates these associations. Close attention to and active improvement of mental health in RA patients will be critical to decrease all-cause mortality and CVD-related mortality.

Even partly consolidated memories can be forgotten given sufficient time, but the brain activity associated with durability of episodic memory at different time scales remains unclear. Here, we aimed to identify brain activity associated with retrieval of partly consolidated episodic memories that continued to be remembered in the future. Forty-nine younger (20 to 38 years; 25 females) and 43 older adults (60 to 80 years, 25 females) were scanned with functional magnetic resonance imaging during associative memory retrieval 12 h post-encoding. Twelve hours is sufficient to allow short-term synaptic consolidation as well as early post-encoding replay to initiate memory consolidation. Successful memory trials were classified into durable and transient source memories based on responses from a memory test ~6 d post-encoding. Results demonstrated that successful retrieval of future durable vs. transient memories was supported by increased activity in a medial prefrontal and ventral parietal area. Individual differences in activation as well as the subjective vividness of memories during encoding were positively related to individual differences in memory performance after 6 d. The results point to a unique and novel aspect of brain activity supporting long-term memory, in that activity during retrieval of memories even after 12 h of consolidation contains information about potential for long-term durability.

We question Spelke's key claim that the medium, in which contents from different core knowledge systems can be represented and combined, is language-based. Recalling an episodic memory, playing chess, and conducting mental rotation are tasks where core knowledge information is represented and combined. Although these tasks can be by means of language, these tasks are not inherently language-based. Hence, language may be an important of an abstraction medium - not the medium as such.

Depression is a major psychological disorder with a growing impact worldwide. Traditional methods for detecting the risk of depression, predominantly reliant on psychiatric evaluations and self-assessment questionnaires, are often criticized for their inefficiency and lack of objectivity. Advancements in deep learning have paved the way for innovations in depression risk detection methods that fuse multimodal data. This paper introduces a novel framework, the Audio, Video, and Text Fusion-Three Branch Network (AVTF-TBN), designed to amalgamate auditory, visual, and textual cues for a comprehensive analysis of depression risk. Our approach encompasses three dedicated branches-Audio Branch, Video Branch, and Text Branch-each responsible for extracting salient features from the corresponding modality. These features are subsequently fused through a multimodal fusion (MMF) module, yielding a robust feature vector that feeds into a predictive modeling layer. To further our research, we devised an emotion elicitation paradigm based on two distinct tasks-reading and interviewing-implemented to gather a rich, sensor-based depression risk detection dataset. The sensory equipment, such as cameras, captures subtle facial expressions and vocal characteristics essential for our analysis. The research thoroughly investigates the data generated by varying emotional stimuli and evaluates the contribution of different tasks to emotion evocation. During the experiment, the AVTF-TBN model has the best performance when the data from the two tasks are simultaneously used for detection, where the F1 Score is 0.78, Precision is 0.76, and Recall is 0.81. Our experimental results confirm the validity of the paradigm and demonstrate the efficacy of the AVTF-TBN model in detecting depression risk, showcasing the crucial role of sensor-based data in mental health detection.

BACKGROUND
Rheumatoid arthritis (RA) patients often encounter psychological challenges due to chronic pain, fatigue, side effects of medications, and disability. This study examines the relationship between autobiographical narratives and recollection patterns in RA patients. We investigated how different recall strategies for positive life events affect the emotional processing of negative episodes. We hypothesized that vividly recalling positive life events provides psychological resources that support a more intense emotional elaboration of stressful memories, allowing individuals to delve deeper into negative life experiences. Additionally, we explored the impact of these perspectives on self-reported well-being and physical health, proposing that re-living positive events improves overall well-being.
METHODS
We collected and analyzed high-point and low-point life-story episodes from 60 RA patients (85% female; age mean 61 ± 11 years; range 37-79) using episodic narrative interviews and the Narrative Categorical Content Analysis algorithm (NarrCat). Participants were categorized into 2 clusters based on their temporal perspective during high-point episodes: 25 used a Retrospective viewpoint, while 35 employed a Re-experiencing strategy. Depression and anxiety were assessed with the Hospital Anxiety and Depression Scale (HADS), and functioning was measured using the Health Assessment Questionnaire (HAQ).
RESULTS
The Re-experiencing group, which was more likely to articulate their high-point episode in vivid and real-time narrative, used more psychological perspectives (U(58) = 223, < 0.01) and showed heightened emotional frequency (U(58) = 280, < 0.05; positive: U(58) = 328, < 0.05; negative: U(58) = 278, < 0.05) in low-point episodes. No significant difference emerged between the two groups regarding psychological state (anxiety, depressive symptoms) and physical impairment.
CONCLUSIONS
Vividly recalling positive events may facilitate a deeper exploration of negative memories. The Re-experiencing group showed increased positive emotions during low points, suggesting better emotion regulation. However, no significant association was found between recalling strategies, psychological state, and physical impairment. This indicates that further research is needed to determine whether re-experiencing positive life events is adaptive or maladaptive.

Porcine Liver Decomposition Product (PLDP) was obtained by treating pig liver homogenate with protease and filling it into capsules. We have already confirmed from three clinical trials that PLDP enhances visual memory and delays memory recall, and we believe that its activity is due to various phospholipids, including phosphatidylcholine (PC). In this study, we clinically evaluated PLDP for depressive symptoms caused by a decline in cognitive function. This clinical trial was conducted using the Revised Hasegawa Dementia Scale (HDS-R). The HDS-R (maximum score is 30 points) is a test similar to the Mini-Mental State Examination (MMSE), which is commonly used in Japan. Dementia is suspected if the score falls below 20 on the HDS-R. Additionally, in a previous clinical trial, there was no change in scores in the placebo group after three doses of the HDS-R. In order to clearly confirm the effectiveness of PLDP, this study was conducted under stricter conditions (HDS-R points of 15 to 23) than previous clinical trials (all participants had scores of 20 or higher). Therefore, from ethical considerations, a clinical trial was conducted using the scores before PLDP administration as a control. In this study, PLDP was administered orally at 4 capsules per day, and the HDS-R was confirmed 2 and 4 weeks after administration. A significant increase in HDS-R scores was observed at 2 and 4 weeks after PLDP administration. Additionally, regarding each item of the HDS-R, PLDP significantly increased 2 and 4 weeks after oral administration for the question items assessing delayed recall, and the question item assessing verbal fluency tasks was recognized. From the above results, we confirmed the reproducibility of the effect of PLDP in improving the delayed recall of verbal memories. Furthermore, increasing scores on verbal fluency tasks suggest that PLDP may enhance frontal lobe function and prevent or improve depressive symptoms. The effects observed in this study may differ from the mechanisms of action of existing antidepressants, and we believe that this may lead to the discovery of new antidepressants.

OBJECTIVES
Videoconference psychotherapy (VCP) is a crucial component of many health care systems, allowing for remote delivery of services. However, little is known about the mechanisms of change within VCP. Previous research has suggested that self-disclosure may be greater in VCP than face-to-face modalities and was investigated in the current study.
DESIGN
Young adults aged 18-25 years (N = 57) were randomly allocated to face-to-face or VCP interview conditions, with measures completed pre- and post-interview.
METHODS
Participants completed an autobiographical memory task, requiring them to describe specific memories in response to positive and negative valence cue words. Measures included self-reported self-disclosure, blind observer-rated self-disclosure, memory specificity, and mean number of words per response.
RESULTS
No significant differences were found between conditions with regard to self-reported self-disclosure, capacity to recall specific memories, or words uttered per response. However, observer-rated depth of self-disclosure was significantly higher for participants in the face-to-face than VCP condition. Self-disclosure and memory specificity were also significantly greater for negative than positive valence cue words, regardless of condition.
CONCLUSIONS
The findings indicate that whilst participants may be able to draw on memories with equal ease regardless of interview modality, in VCP, emotional processing of these memories may require increased support and guidance from the therapist.

Adverse childhood experiences (ACEs) include a range of abusive, neglectful, and dysfunctional household behaviors that are strongly associated with long-term health problems, mental health conditions, and societal difficulties. The study aims to uncover significant factors influencing ACEs in children aged 0-17 years and to propose a predictive model that can be used to forecast the likelihood of ACEs in children. Machine learning models are applied to identify and analyze the relationships between several predictors and the occurrence of ACEs. Key performance metrics such as AUC, F1 score, recall, and precision are used to evaluate the predictive strength of different factors on ACEs. Family structures, especially non-traditional forms such as single parenting, and the frequency of relocating to a new address are determined as key predictors of ACEs. The final model, a neural network, achieved an AUC of 0.788, a precision score of 0.683, and a recall of 0.707, indicating its effectiveness in accurately identifying ACE cases. The model's ROC and PR curves showed a high true positive rate for detecting children with two or more ACEs while also pointing to difficulties in classifying single ACE instances accurately. Furthermore, our analysis revealed the intricate relationship between the frequency of relocation and other predictive factors. The findings highlight the importance of familial and residential stability in children's lives, with substantial implications for child welfare policies and interventions. The study emphasizes the need for targeted educational and healthcare support to promote the well-being and resilience of at-risk children.

The COVID-19 pandemic and the resulting lockdown countermeasure may have significantly affected adolescents' physical and mental health. This study aims to assess adolescents' recollections of this period, also analyzing their current weight status along with factors they traced back to the epidemic phase and their current sports practice. A survey among 233 Italian adolescents aged 12.4 ± 0.9 years was conducted in October 2023. To achieve the research objectives, a new questionnaire was developed: the COVID-19 AdolesceNt/chilDren Lockdown Experience questionnaire (CANDLE). The new questionnaire was employed to gather data on the adolescents' recollections of the lockdown situation they experienced. The stature and weight of participants were measured directly. The results indicated that middle schoolers remember both positive and negative experiences of the lockdown: the change perceived as the most positive was spending more time with family, while social detachment from peers represents the most negative aspect. According to multivariate regression analysis, certain behaviors they assumed during the lockdown, such as comfort food consumption in boys and sleeping disturbances in girls, in addition to their current sports practice, affected their actual Body Mass Index. This study supports the evidence that changes caused by the COVID-19 lockdown affected adolescents' physical and mental health, albeit with sex differences.
