Estrogens exert effects on cognition by acting on estrogen receptors (ER) including ERα. Activation of nuclear ERα results in classical genomic signaling leading to transcriptional changes that occur over hours to days. In contrast, activation of ERα localized to the membrane results in rapid signaling with effects occurring in seconds to minutes. The goal of the current study was to determine the role of membrane ERα in spatial memory. Female wildtype (WT) and transgenic mice that lack membrane ERα and express nuclear only ERα (NOER) were trained on an eight-arm radial-maze task. Following training, mice were tested on delay trials, in which delays ranging from 30 min to 5 h were inserted between the 4th and 5th arm choices. Performance was measured by number of proactive and retroactive errors. Proactive errors are short-term working memory errors defined by reentries into arms previously visited during the post-delay period or errors made during the pre-delay period. Retroactive errors are delay-dependent memory errors, defined as reentries into arms during the post-delay that were previously visited during the pre-delay. Consistent with a role for membrane ERα in rapid signaling, NOER mice made more proactive errors than WTs across all delays. NOER mice made more retroactive errors than WTs only after the 5-h delay. WT and NOER mice performed similarly on elevated plus maze and open field tests indicating no effects of membrane ERα on anxiety-related behavior or locomotor activity. Results reveal that membrane ERα plays important roles in both short-term and longer-term delay-dependent memory either directly or potentially indirectly through a role in the regulation of estradiol levels via the hypothalamic-pituitary-gonadal axis.

OBJECTIVE
To compare and correlate musical performance anxiety (MPA) and vocal self-perception among amateur evangelical singers, focusing on the interaction between anxiety and aspects of performance in this sample.
METHOD
This study employed a cross-sectional and quantitative approach, involving 75 amateur gospel singers from evangelical churches, aged between 18 and 59 years. Data collection included the administration of a sample identification and characterization questionnaire, the Brazilian Portuguese version of the Kenny Music Performance Anxiety Inventory (K-MPAI), and the Singing Voice Handicap Index (S-VHI). The descriptive analysis used absolute and relative frequencies, measures of central tendency, and dispersion (mean and standard deviation [SD]). To compare the vocal self-assessment protocols and performance aspects, the Kruskal-Wallis test was applied. Spearman's correlation test was used for correlation analysis. All analyses were conducted with a significance level set at 5% (P < 0.05).
RESULTS
Vocal warm-up and cool-down activities, vocal discomfort after performance, and vocal self-assessment were significantly associated with scores on S-VHI, and the variable "instruments louder than voices" was associated with the K-MPAI score. Participants exhibited a mean K-MPAI score of 85.12 points (SD ± 36.6), and the vocal handicap of the sample had a mean score of 45.22 (SD ± 32.3). There was no statistically significant correlation between the protocols.
CONCLUSION
Incorporating vocal warm-up and cool-down activities was significantly associated with lower scores on S-VHI. Conversely, those experiencing postperformance vocal discomfort exhibited higher scores on S-VHI. Moreover, the absence of correlation between the assessment protocols suggests that while significant levels of voice handicap were observed, a direct link to MPA cannot be definitively established. Overall, these findings contribute to a nuanced understanding of the multifaceted factors shaping vocal health and performance among amateur evangelical singers, thereby guiding future research and interventions in this field.

Prenatal exposure to benzodiazepine and z-hypnotics and fifth-grade scholastic skills - emulating target trials using data from the Norwegian Mother, Father and Child Cohort Study.
Evidence is limited regarding the effect of prenatal benzodiazepine and z-hypnotic exposure and long-term neurodevelopment in childhood. The objective of this study was to investigate the effects of initiating benzodiazepine or z-hypnotic treatment in early, mid and late pregnancy on fifth-grade numeracy and literacy scholastic skills in children, by emulating three target trials. The trials are identical except for the timing of enrollment and the number of eligible individuals. Eligibility to the trials required a history of anxiety and/or depression prior to pregnancy. We used data from the Norwegian Mother, Father and Child Cohort Study, linked to the Medical Birth Registry of Norway, to emulate the trials. We adjusted for baseline covariates that were available at time 0 for each trial by inverse probability of treatment weighting using the propensity score. The findings of this study did not show any effect of mothers' initiation of treatment with benzodiazepines or z-hypnotics in early, mid or late pregnancy on the children's 5th grade test scores in numeracy and literacy. The study results provide reassurance for patients in need of benzodiazepines and z-hypnotics during pregnancy; however, these findings need to be interpreted with caution due to low study power in some of the analyses.

Cranial electrotherapy stimulation (CES) is a form of non-invasive brain stimulation (NIBS) that has demonstrated potential to modulate neural activity in a manner that may be conducive to improved cognitive performance. While other forms of NIBS, such as transcranial direct current stimulation (tDCS), have received attention in the field as potential acute cognitive enhancers, CES remains relatively unexplored. The current study aimed to assess the efficacy of CES in improving acute cognitive performance under normal experimental conditions, as well as during sessions of induced situational anxiety (threat of shock or ToS). To study this question, participants completed a cognitive battery assessing processing speed and distinct aspects of executive functioning (working memory, inhibition, and task switching) in two separate sessions in which they received active and sham CES. Participants were randomly assigned to between subject groups of either situational anxiety (ToS) or control condition (no ToS). We predicted that active CES would improve performance on assessments of executive functioning (working memory, inhibition, and task switching) relative to sham CES under ToS. We did not find any significant effects of ToS, CES, or an interaction between ToS and CES for any measures of executive functioning or processing speed. These findings suggest that a single dose of CES does not enhance executive functioning or processing speed under normal conditions or during ToS.

Numerous studies on post-COVID syndrome (PCS) describe persisting symptoms of cognitive impairment. Previous studies, however, often investigated small samples or did not assess covariates possibly linked to cognitive performance. We aimed to describe 1) global and domain-specific cognitive performance in adults with PCS, controls with previous SARS-CoV-2 infection and healthy controls, 2) associations of sociodemographics, depressive symptoms, anxiety, fatigue, somatic symptoms and stress with cognitive performance and subjective cognitive decline (SCD), using data of the LIFE-Long-COVID-Study from Leipzig, Germany. Group differences in cognitive performance and associations with sociodemographic and neuropsychiatric covariates were assessed using multivariable regression analyses. Our study included n = 561 adults (M: 48.8, SD: 12.7; % female: 70.6). Adults with PCS (n = 410) performed worse in tests on episodic memory (b = -1.07, 95 % CI: -1.66, -0.48) and visuospatial abilities (b = -3.92, 95 % CI: -6.01, -1.83) compared to healthy controls (n = 64). No impairments were detected for executive function, verbal fluency, and global cognitive performance. Odds of SCD were not higher in PCS. A previous SARS-CoV-2 infection without PCS (n = 87) was not linked to cognitive impairment. Higher age and higher levels of stress and fatigue were linked to worse performance in several cognitive domains. Routine administration of tests for episodic memory and visuospatial abilities might aid in the identification of individuals at risk for cognitive impairment when reporting symptoms of PCS. Low numbers of participants with severe COVID-19 infections possibly limit generalizability of our findings.

This pilot study evaluated the impact of pistachio consumption on cognitive performance and mood in overweight young adults. Pistachios were characterized (chemical and nutraceutical), and a baseline-final, uncontrolled nutritional intervention was performed (28 g of pistachio/28 days). Psychometric tests were applied to estimate cognitive performance and mood; anthropometric evaluation, biochemical analysis, and plasma antioxidant activity were included. The main component of nuts was lipids (48.1%). Pistachios consumption significantly (p ≤ 0.05) reduced waist circumference (-1.47 cm), total cholesterol (-10.21 mg/dL), LDL (-6.57 mg/dL), and triglycerides (-21.07 mg/dL), and increased plasma antioxidant activity. Pistachio supplementation improved risk tolerance (p ≤ 0.006) and decision-making strategy (p ≤ 0.002; BART-task), executive functions (BCST-task; p ≤ 0.006), and selective and sustained attention (Go/No-Go-test; p ≤ 0.016). The mood state was positively modulated (p ≤ 0.05) for anxiety, anger-hostility, and sadness-depression. These results show for the first time the benefits of pistachio consumption on cognitive performance and mood in overweight young adults.

BACKGROUND
Suicide is a significant public health issue. Many risk prediction tools have been developed to estimate an individual's risk of suicide. Risk prediction models can go beyond individual risk assessment; one important application of risk prediction models is population health planning. Suicide is a result of the interaction among the risk and protective factors at the individual, health care system, and community levels. Thus, policy and decision makers can play an important role in suicide prevention. However, few prediction models for the population risk of suicide have been developed.
OBJECTIVE
This study aims to develop and validate prediction models for the population risk of suicide using health administrative data, considering individual-, health system-, and community-level predictors.
METHODS
We used a case-control study design to develop sex-specific risk prediction models for suicide, using the health administrative data in Quebec, Canada. The training data included all suicide cases (n=8899) that occurred from January 1, 2002, to December 31, 2010. The control group was a 1% random sample of living individuals in each year between January 1, 2002, and December 31, 2010 (n=645,590). Logistic regression was used to develop the prediction models based on individual-, health care system-, and community-level predictors. The developed model was converted into synthetic estimation models, which concerted the individual-level predictors into community-level predictors. The synthetic estimation models were directly applied to the validation data from January 1, 2011, to December 31, 2019. We assessed the performance of the synthetic estimation models with four indicators: the agreement between predicted and observed proportions of suicide, mean average error, root mean square error, and the proportion of correctly identified high-risk regions.
RESULTS
The sex-specific models based on individual data had good discrimination (male model: C=0.79; female model: C=0.85) and calibration (Brier score for male model 0.01; Brier score for female model 0.005). With the regression-based synthetic models applied in the validation data, the absolute differences between the synthetic risk estimates and observed suicide risk ranged from 0% to 0.001%. The root mean square errors were under 0.2. The synthetic estimation model for males correctly predicted 4 of 5 high-risk regions in 8 years, and the model for females correctly predicted 4 of 5 high-risk regions in 5 years.
CONCLUSIONS
Using linked health administrative databases, this study demonstrated the feasibility and the validity of developing prediction models for the population risk of suicide, incorporating individual-, health system-, and community-level variables. Synthetic estimation models built on routinely collected health administrative data can accurately predict the population risk of suicide. This effort can be enhanced by timely access to other critical information at the population level.

Previous research has suggested that math anxiety may contribute to poor math performance by interfering with working memory. However, only a limited number of studies investigated the mediating role of working memory in the math anxiety-math performance link in school-aged children. Unlike math anxiety, ego-resiliency is a personality resource that promotes the management of challenges and has been positively associated with math performance and negatively with anxiety. Nevertheless, there is still limited understanding regarding the specific role of ego-resiliency in math learning and how it relates to math anxiety. This study aimed to investigate conjunctly the interplay between primary school children's ego-resiliency, math anxiety, working memory, and performance on two different math tasks (i.e., arithmetic task and word problem-solving task), after controlling for general anxiety and age. The study involved 185 Italian children from grades 3 to 5. Serial multi-mediational analyses revealed that: (1) ego-resiliency has a positive indirect effect on math achievement through two paths - math anxiety, and math anxiety and working memory; (2) the study replicated previous findings showing that working memory partially mediated the relationship between math anxiety and math performance; (3) similar patterns of results were found for both math skills. The study identifies ego-resiliency as a possible protective factor in the development of math anxiety and suggests that ego-resiliency could be worth considering when designing interventions aimed at reducing negative emotions towards mathematics.

The prevalence of mental health issues among UK undergraduate students is growing, and poor diet quality appears to be a risk factor for poor mental health although with limited research in this area. Therefore, the objective of this study was to examine the cross-sectional associations between diet quality and common mental disorders (CMD) such as depression and anxiety in UK undergraduate students. A cross-sectional survey consisting of demographic information and validated questionnaires (the Short-Form Food Frequency Questionnaire [SFFFQ] and the Hospital Anxiety and Depression Scale [HADS]) was conducted to measure diet quality and anxiety and depression in young adults in 44 UK-based universities. Multiple regression analysis adjusting for confounding factors was used to assess the associations between them. Undergraduate university students (n = 202, 67% female) with a mean age of 20.9 ± 3.6 years and a mean body mass index (n = 170) of 22.6 ± 3.2 kg/m took part in the study. Prevalence of anxiety was high, with 40% of the sample having an anxiety score in the severe range (≥12 points) while the prevalence of depression was lower, with 6% of the population having a depression score in the severe range (≥12 points). Diet quality was significantly higher for females than males (p = 0.034) and was poor for 38% of the sample, being more common in males compared to females, although not significantly so (43% and 36%, respectively). Diet quality was inversely associated with anxiety (β = -0.427; p = 0.029) and was more likely to be associated with anxiety in females than males (β = 0.743; p = 0.043). No significant relationship between diet quality and depression was found. Better self-reported health, father's qualification and smoking status were also associated with less anxiety and depression. This research supports other research suggesting that UK universities should explore whether the implementation of dietary interventions and improving the food environment would be a cost-effective option to reduce the high prevalence of anxiety among students.

INTRODUCTION
Elite and recreational climbers may be at risk for disordered eating, low energy availability (LEA), and increased injury as a result. Social media use among athlete and non-athletes can lead to body image disturbances resulting in unhealthy weight loss practices exacerbating LEA and injury risk. Therefore, the objective of this study was to examine relationships between social comparative behaviors on social media, body type ideals and outcomes, and health behaviors among adult recreational climbers.
METHODS
Participants ( = 324) were adult recreational climbers from the U.S. (29.30 ± 9.99 years old and 50% female). Participants answered a 66-item questionnaire comprised of demographics, climbing characteristics, social media behaviors, body type ideals, training and nutrition-seeking behaviors, and weight and food tracking behaviors.
RESULTS
Most participants (78.7%) indicated strength-to-weight ratio was important for climbing performance. Many participants perceived they could perform better at rock climbing if their body proportions were different (59.3%). These body type ideals were found to be significant predictors of performing weight loss and food-tracking behaviors (all < 0.001). Higher amounts of social comparative behaviors on social media and social physique anxiety independently and significantly predicted attempting weight loss to improve climbing ability ( < 0.001 and = 0.001 respectively). Those who followed climbing influencers, used Instagram frequently for training and nutrition information, perceived they could perform better at rock climbing if their body proportions were different, or were female and college-aged had significantly higher mean social comparative behavior scores (all < 0.01).
DISCUSSION
This study expands on prior work with elite climbers by providing a possible explanation for how climbing-related body type ideals and certain social media behaviors can perpetuate negative body image and compensatory behaviors among a general climbing population. Because unhealthy weight management behaviors can lead to injury and health disturbances, broad education programming and social media campaigns should be developed to shift body ideals and nutrition behaviors among recreational climbers.
