A-161 Corticomedial Amygdala Volume Significantly Predicts Cognitive Fexibility in an Older Adult Sample

Abstract Objective The present study examined the relationship between anxiety, corticomedial and basolateral amygdala volume, and cognitive flexibility among older adults (OA). We hypothesized that higher subclinical Beck Anxiety Inventory (BAI) scores would be associated with lower cognitive flexibility, assessed using the Delis-Kaplan Executive Function System (D-KEFS) verbal fluency. Additionally, we hypothesized that basolateral amygdala volume would negatively correspond to anxiety scores and exhibit a positive relationship with cognitive flexibility. Method Sixty-three OA (M age: 65; SD: 9; 59% female) were recruited via community advertising and cardiac clinics for a parent study on cardiovascular disease. Participants completed the D-KEFS and BAI as part of a comprehensive neuropsychological assessment prior to magnetic resonance imaging (MRI). Amygdala segmentation was completed with FreeSurfer version 6.0, using T1-weighted MPRAGE and T2-weighted FLAIR images. Data was analyzed using hierarchical multiple regression, controlling for age, sex, years of education, and intracranial volume. Results No significant relationship emerged between basolateral amygdala volume and BAI scores (r = .11, p = .41) or cognitive flexibility (r = .04, p = .76). However, a significant positive relationship was observed between corticomedial amygdala volume and cognitive flexibility after controls (β = 0.37, p < .01). Conclusions The previously reported relationship between high anxiety and basolateral amygdala volume does not appear to extend to subclinical levels. We conjecture that the significant relationship between the corticomedial amygdala and cognitive flexibility represents the upward slope between arousal and cognitive performance on the Yerkes-Dodson curve. These findings newly implicate corticomedial amygdala volume as a representative measure linking emotional arousal and cognitive performance in OA.

Framework Approach

Abstract From a conditional adaptation vantage point, early life caregiving adversity likely enhances aspects of cognition needed to manage interpersonal threats. Yet, research examining early life care and offspring cognition predominantly relies upon experiments including affectively neutral stimuli, with findings generally interpreted as “early-life caregiving adversity is, de facto, ‘bad’ for cognitive performance.” Here, in a Southeast Asian sample, we examined observed maternal sensitivity in infancy and cognitive performance 3 years later as preschoolers took part in three tasks, each involving both a socioemotional (SE) and non-socioemotional (NSE) version: relational memory (n = 236), cognitive flexibility (n = 203), and inhibitory control (n = 255). Results indicate the relation between early life caregiving adversity and memory performance significantly differs (Wald test = 7.67, (1), P = 0.006) depending on the SE versus NSE context, with maternal sensitivity in infancy highly predictive of worse memory for SE stimuli, and amongst girls, also predictive of better memory when NSE stimuli are used. Results concerning inhibitory control, as well as cognitive flexibility in girls, also tentatively suggest the importance of considering the SE nature of stimuli when assessing relations between the caregiving environment and cognitive performance. As not all approaches to missing data yielded similar results, implications for statistical approaches are elaborated. We conclude by considering how an adaptation-to-context framework approach may aid in designing pedagogical strategies and well-being interventions that harness pre-existing cognitive strengths.

Basal Ganglia Structures

Abstract Cognitive deficits occur in patients with Parkinson’s disease (PD), and cardiorespiratory fitness (CRF) is associated with both current and future cognitive decline in this disease. The underlying neurobiological factors explaining this relationship, however, are not well known. In this cross-sectional study we examined the associations between CRF and cognitive performance and whether such associations were mediated by grey matter volumes of basal ganglia structures. A total of 33 individuals with PD underwent structural magnetic resonance imaging (sMRI), CRF evaluation (VO2max), and neuropsychological assessment. Composite scores of episodic memory, executive functioning, attention, language, and visuospatial functioning were generated. Brain MRI morphological measurements was performed with the Freesurfer image analysis suite. Structural equation models were constructed to examine whether sMRI volume estimates of basal ganglia structures, specifically the thalamus and pallidum, mediated associations between VO2 max and cognitive performance while adjusting for age, education, PD disease duration, sex, and intracranial volume. Higher VO2max was associated with better episodic memory (Standardized β=0.390; p=0.009), executive functioning (Standardized β=0.263; p=0.021), and visuospatial performance (β=0.408; p=0.004). Higher VO2max was associated with larger thalamic (Standardized β=0.602; p<0.001) and pallidum (Standardized β=0.539; p<0.001) volumes. Thalamic volume significantly mediated the association between higher VO2max and better episodic memory (indirect effect=0.209) and visuospatial ability (indirect effect=0.178) performance (p<.05). The pallidum did not significantly mediate associations between VO2 max and cognitive outcomes. These results suggest the thalamus plays an important role in the association between CRF episodic memory and visuospatial functioning in individuals with PD.

El tamaño es una variable contingente que puede influir en los resultados de las empresas. En este trabajo se pretende contrastar la existencia o no de una relación significativa entre tamaño y resultados empresariales de las empresas agrarias, en particular de las cooperativas hortofrutícolas españolas. Para ello, se realiza un estudio empírico en base a la información económica y financiera obtenida de los registros oficiales de las cooperativas agrarias dedicadas a la comercialización de frutas y hortalizas sobre el cual se ha aplicado un análisis de regresión. El estudio demuestra que no existe una relación significativa positiva entre los resultados empresariales y el tamaño de este tipo de entidades, por lo que se puede afirmar que la capacidad competitiva de una empresa agraria depende de su propia capacidad de gestión y no de un factor de contingencia como el tamaño. ABSTRACTSize is a contingency variable that can influence firms’ performance. This study aims to contrast whether exists or not a significant relationship between organizational size and performance in agrifood firms, particularly in the case of Fruit and Vegetables Cooperatives in Spain. Therefore, an applied empirical study using regression analysis is carried out from economic and financial information of such companies obtained from official registers. The study shows that there is not a significant positive relationship between performance and size for such type of firms.

Management of working capital is a fundamental aspect of finance. This is because it affects the church's liquidity and financial sustainability. The study sort of establishing the relationship between working capital and financial sustainability for selected Christian denominations in Ghana. Using bivariate correlation application in SPSS 23, the financial statements from 2013 to 2017 of 15 Christian Council of Ghana denominational members conveniently sampled and analyzed. Working capital is represented by liquidity ratios of current ratio, and cash ratio and financial sustainability are epitomized by self-support. The study revealed that there was a positive relationship between working capital and financial sustainability among Christian denomination in Ghana. In a detailed outcome, there was a statistically small positive significant relationship between self-support and cash ratio and statistically large positive significant relationship between self-support and current ratio. The study recommends to churches in Ghana to seek an enhancing relationship between their working capital and financial sustainability to prevent a possible closure of the church. Not-for-profit organizations must seek self-support through income generation and diversification to improve their Liquidity. Again, not-for-profit organizations must have a positive relationship between working capital and financial sustainability in that churches exist because of liquidity.

OBJECTIVE: This study investigated the thickening of the ligamentum flavum (LF) and its correlation with facet tropism and its severity at different levels of the spine. METHOD: This retrospective study was performed with patients with chronic back pain consecutively admitted to a specialized spinal surgery service between January 2012 and January 2013. All patients underwent magnetic resonance imaging (MRI) to measure the thickness of the LF and facet tropism severity (severe, moderate or absent) according to the spine levels (L3 -L4, L4-L5, L5-S1). The association between the thickness of LF and facet tropism was analyzed. RESULTS: During the study period, 98 consecutive patients were enrolled with a mean age of 53.6 years, most women (59.2%). There was no significant difference between the thicknesses of the ligament and the presence of tropism in different spinal levels (p > 0.05). The thickness of LF was significantly associated with the severity of tropism only in L5-S1 level (p < 0.03). CONCLUSIONS: Our results show that there is a positive relationship between severe facet tropism and increased thickness of the LF in the L5-S1 level.

Abstract Objective The purpose of this study was to observe the effects of self-reported affective, sleep, and vestibular-somatic symptomatology on cognitive performance at baseline as measured by ImPACT. Method Participants were selected from a de-identified archival database of high school athletes aged 13–18. Symptom clusters included affective (N = 435, 61.7% female, Mage = 15.46), sleep (N = 435, 53.8% female, Mage = 15.49), and vestibular-somatic (N = 435, 52.2% male, Mage = 15.31). Three One-Way ANOVAs compared baseline composite scores between athletes who reported varying levels of symptomatology within each symptom cluster. Athletes were divided into groups based on their reported symptoms: None (n = 145), Mild (n = 145), and Moderate/Severe (n = 145). Significance was found at p = 0.01. Results No significant relationship between self-reported affective or sleep symptomatology and cognitive performance was observed. A significant relationship was shown between self-reported vestibular-somatic symptomatology regarding the Visual-Motor composite [F (2,432) = 5.925, p = .003]. Bonferroni pairwise comparisons revealed athletes with no reported vestibular-somatic symptoms performed significantly better on Visual-Motor tasks than those with Mild and Moderate/Severe symptoms. Conclusions These results may assist in the understanding of the influence of symptoms reported by athletes’ post-concussion. While those with varying levels of vestibular-somatic symptomatology were found to have significantly different performance on Visual-Motor tasks, this cluster of symptoms was not found to impact other domains of cognitive functioning. The influence of symptoms on cognitive performance likely varies between individual athletes, which can have implications on return-to-play decisions. This highlights the critical need for an individualized approach to be utilized when evaluating athletes post-concussion considering the current literature to date.
