Poor Diet, Long Sleep, and Lack of Physical Activity Are Associated with Inflammation among Non-Demented Community-Dwelling Elderly.

Inflammation in elderly is associated with physical and cognitive morbidity and mortality. We aimed to explore the association of modifiable lifestyle parameters with inflammation among non-demented, community-dwelling elderly. A sub-sample of 117 patients with mild cognitive impairment (MCI, n = 63) and cognitively non-impaired controls (CNI, n = 54) were recruited from a large, population-based cohort in Crete, Greece, of 3140 elders (>60 years old). All participants underwent assessment of medical history/physical examination, extensive neuropsychiatric/neuropsychological evaluation, diet, three-day 24-h actigraphy, subjective sleep, physical activity, and measurement of IL-6 and TNFα plasma levels. Associations between inflammatory markers and diet, objective sleep duration, subjective sleep quality, and lack of physical activity were assessed using multivariate models. Regression analyses in the total group revealed significant associations between TNF-α and low vegetable consumption (p = 0.003), and marginally with objective long nighttime sleep duration (p = 0.04). In addition, IL-6 was associated with low vegetable consumption (p = 0.001) and lack of physical activity (p = 0.001). Poor diet and lack of physical activity appear to be modifiable risk factors of inflammation, whereas long sleep appears to be a marker of increased inflammatory response in elderly. Our findings may have clinical implications given the association of inflammatory response with morbidity, including cognitive decline, and mortality in elderly.

Post-COVID-19 psychiatric and cognitive morbidity: Preliminary findings from a Brazilian cohort study

ObjectiveThe present study aims to investigate the occurrence of psychiatric and cognitive impairments in a cohort of survivors of moderate or severe forms of COVID-19. Method425 adults were assessed 6 to 9 months after hospital discharge with a structured psychiatric interview, psychometric tests and a cognitive battery. A large, multidisciplinary, set of clinical data depicting the acute phase of the disease, along with relevant psychosocial variables, were used to predict psychiatric and cognitive outcomes using the ‘Least Absolute Shrinkage and Selection Operator’ (LASSO) method. ResultsDiagnoses of ‘depression’, ‘generalized anxiety disorder’ and ‘post-traumatic stress disorder’ were established respectively in 8%, 15.5% and 13.6% of the sample. After pandemic onset (i.e., within the previous year), the prevalence of ‘depression’ and ‘generalized anxiety disorder’ were 2.56% and 8.14%, respectively. Memory decline was subjectively reported by 51.1% of the patients. Psychiatric or cognitive outcomes were not associated with any clinical variables related to the severity of acute-phase disease, nor by disease-related psychosocial stressors. ConclusionsThis is the first study to access rates of psychiatric and cognitive morbidity in the long-term outcome after moderate or severe forms of COVID-19 using standardized measures. As a key finding, there was no significant association between clinical severity in the acute-phase of SARS-CoV-2 infection and the neuropsychiatric impairment 6 to 9 months thereafter.

Neuroprotective effects of carvacrol against Alzheimer's disease and other neurodegenerative diseases: A review.

Objective:Neurodegenerative diseases are considered an important cause of cognitive deficit and morbidity in old ages. Alzheimer’s disease (AD) is one of these disorders affecting about 40 million people in the world at the present time. Available drug therapy is mostly symptomatic and does not modify or stop disease progression. Recently, biologically active chemicals from herbs have been studied to develop new therapeutic drugs. Carvacrol has shown positive properties on many neurological diseases. This compound is expected to have the ability to affect AD pathogenesis and therefore, it is considered an anti-AD agent. Materials and Methods:This review was conducted using PubMed, Google Scholar and Science Direct bibliographic databases until November 2021. For data collection, the following keywords were used: carvacrol, neuroprotective, cognition, anti-inflammatory, antioxidant, Acetylcolinesterase inhibitor (AChEI), Alzheimer's, Parkinson’s, epilepsy, stroke, ischemic brain injury, and neurodegenerative diseases. Results:This review summarizes in vitro and in vivo studies on protective potential of carvacrol in neurodegenerative disorders and various underlying mechanisms, such as anti-inflammatory, antioxidant, and anticholinesterase effects. Conclusion:We gave an overview of available literature concerning neuroprotective effects of carvacrol in ameliorating the neurodegenerative diseases symptoms in vivo and in vitro. Particular attention is given to AD. Several neuro-pharmacological actions of carvacrol have been summarized in the current review article including anti-inflammatory, antioxidant, and AChEI properties.

Cognitive Profile of Adults with Sickle Cell Disease - Cluster Analysis

Background: Published literature on cognitive functioning in adults with sickle cell disease (SCD) is sparse when compared to children. A few reports describe deficits in processing speed and executive functioning. Some studies suggest that these deficits are more severe in patients with silent cerebral infarcts (SCI). Even in the absence of radiological evidence of ischemic injury, some cognitive deficits have been depicted in adults . We hypothesize that in SCD adults, the cognitive profile varies with the presence of ischemic injury (SCI or overt stroke). The aims of this study were 1) to describe the neuropsychological profiles of SCD adults, and 2) to characterize clusters of patients with similar cognitive profiles.Methods: We conducted a retrospective analysis of all consecutive SCD adults who underwent comprehensive neuropsychological assessment during routine care at the UMGGR clinic at Henri Mondor Hospital, Créteil (France), between January 2017 and April 2021. The Montreal Cognitive Assessment (MoCA) and Hospital Anxiety and Depression Scale (HADS) were used for cognitive disorder, anxiety and depression screening, respectively. The cognitive battery combined standardized neuropsychological tests with established clinical utility and validity. Educational attainment was scored based on the number of years of schooling for the highest completed diploma. Principal component analysis was performed. ANOVA was used to compare patients' characteristics between clusters.Results: 80 patients, median age 36.5 [range 19-63] years were included. 40 (50.0%) were male. Genotype distribution was 62 patients (77.5%) with SS/Sbeta 0, 12 (15.0%) with SC and 6 (7.5%) with Sbeta +. On Principal Component Analysis, a 5-factor model presented the best fit (Bartlett's sphericity test (χ²(171)=1174; p<0.001)), explaining 71.8% of the variance in neuropsychological scores. The first factor encompassed tests specifically assessing visual attention/visual organization (right hemisphere). The second included tests for mental/cognitive control (frontal lobe), the third tests of selective inhibition/attention (fronto-parietal), the fourth tests for language/memory (left temporal lobe) and the last referred to shifting skill (sub-cortical loop). On hierarchical classification, 3 different clusters emerged: 32 patients in cluster 1, 32 in cluster 2 and 16 in cluster 3. Cluster 1 had a lower mean educational level (F(2,77) = 15,65; p<0,001). Cluster 1 showed the lowest mean MoCA score (20.0/30.0), relative to cluster 2 and 3 (24.6 and 26.4; p<0.001 and p<0.001, respectively). Cluster 1 patients presented deficits on all five factors. Cluster 2 patients compared to cluster 3 were altered in 4 factors (factors 1-4), but to a lesser extent than cluster 1. Processing speed was slower and some frontal-executive deficits were present in cluster 2 compared to cluster 3. There was no statistical difference between clusters in terms of ethnic origins. There was a trend for the presence of more cerebral vasculopathy in cluster 1 (chi2; p=0.06). Regarding stroke, 70% occurred during childhood in cluster 1, whereas 70% during adulthood in cluster 2, and 100% during adulthood in cluster 3.Conclusions: Overall, these results suggest at least three different cognitive profiles in adults with SCD: 1) few or no cognitive deficits (cluster 3), 2) some cognitive impairment with a sub-cortical cognitive profile (cluster 2) and 3) more global cognitive impairment with cortical/sub-cortical profile and specific deficits of memory, language and constructional praxis, depending on the location of prior overt neurological events (cluster 1). To reduce the long-term cognitive morbidity of SCD, patients can be identified by their distinct cognitive profiles and neurorehabilitation tailored to their unique profile should be applied. The large proportion of childhood stroke in patients with global cognitive impairment in contrast with majority of those with milder to no cognitive impairment having had their stroke in adulthood emphasize the crucial importance of preventing early childhood stroke and implementing early neurorehabilitation.

Abstract 1122‐000132: Fuoxetine for Recovery After Stroke: A Pooled Analysis of 7165 Patients

Introduction : Stroke is one of the predominant causes of permanent disability, mortality, significant cognitive, physical, and psychosocial morbidity in the world. We conducted this systematic review and meta‐analysis to assess the safety and efficacy of fluoxetine for recovery stroke patients through different time points of follow up. Methods : We searched in PubMed, Cochrane Library, Scopus, and Web of Science databases/ search engines until June 2021. Mean difference (MD) with 95% confidence interval (CI) was applied for continuous data, while risk ratio (RR) with 95% CI was used for dichotomous data. Results : Seventeen randomized clinical trials were identified which assessed the safety and efficacy of fluoxetine compared to placebo for stroke patients. Fluoxetine enhances the National Institutes of Health Stroke Scale (NIHSS) score [MD = ‐0.67, 95 % CI (‐1.19 to ‐0.15), P = 0.01] and the Fugl‐Meyer Motor Scale (FMMS) score [MD = 17.36, 95 % CI (12.12 to 22.61), P &lt;0.00001] at three months follow up. However, the NIHSS score showed no significant difference between the two groups at two weeks [MD = ‐0.32, 95% CI (‐0.72 to 0.07), p = 0.11] or at six months [MD = ‐0.17,95% CI (‐0.47 to 0.14), p = 0.29]. Fluoxetine and placebo‐treated patients had the same overall impact on FMMS scores at one month [MD = 7.77, 95 % CI (‐10.57 to 26.11), P = 0.41]. The fluoxetine arm had a higher risk of broken bone (RR = 2.30, 95% CI [1.59, 3.32], p &lt; 0.001) and hyponatremia (RR = 2.12, 95% CI [1.19, 3.76], p = 0.01) with lower risk of new depression (RR = 0.72, 95% CI [0.61, 0.84], p&lt; 0.001) in comparison to the placebo arm. Conclusions : The efficacy of fluoxetine is likely to take time to emerge, and is expected to be transient. The use of fluoxetine increased the incidence of hyponatremia and bone fractures while decreasing the risk of new‐onset depression.

Fatigue, perceived stigma, self-reported cognitive deficits and psychological morbidity in patients recovered from COVID-19 infection.

BackgroundFew studies have highlighted multiple psychosocial and physical outcomes in patients with COVID-19 infection after recovery. However, the data from developing countries is limited.AimTo evaluate psychological morbidity, post-traumatic stress disorder (PTSD), fatigue, and perceived stigma among patients with COVID-19 after recovery from the acute phase of COVID-19 infection.MethodsIn a cross-sectional online survey, 206 adult patients (age>18 years), recovered from COVID-19 infection completed the Patient Health Questionnaire-4 (PHQ-4), the Impact of Events Scale-Revised (IES-R), Fatigue Severity Scale (FSS), 4 items self-designed questionnaire evaluating cognitive deficits and self-designed questionnaire to evaluate perceived stigma. Additionally, they completed the information about demographic and clinical information.ResultsThe prevalence of anxiety, depressive symptoms, and PTSD in the study sample was 24.8 %, 23.8 %, and 30 % respectively. About three-fifths of the participants (61.2 %) had at least one fatigue symptom as per the FSS with the mean FSS score being 32.10 ± 15.28. About one-fourth of the participants (23.7 %) reported “feeling confused and always feeling mentally foggy”, and 38 % of patients reported experiencing at least one cognitive problem. The level of felt stigma related to self was seen in 31.1 %, 20 % reported stigma related to family, and 50 % reported stigma in relation to neighbors and society. Those reporting higher PTSD scores had higher anxiety and depressive scores, reported more fatigue and stigma, and had a higher level of cognitive deficits. A higher fatigue score was also associated with higher anxiety, depression, and cognitive deficits.ConclusionsOur study reveals that a significant proportion of patients after recovery from COVID-19 experience psychological morbidities, fatigue, cognitive problems, and stigma. Efforts should be made to take care of these issues in routine post-COVID follow-up care.

Reducing the Cognitive Footprint of Brain Tumor Surgery.

The surgical management of brain tumors is based on the principle that the extent of resection improves patient outcomes. Traditionally, neurosurgeons have considered that lesions in “non-eloquent” cerebrum can be more aggressively surgically managed compared to lesions in “eloquent” regions with more known functional relevance. Furthermore, advancements in multimodal imaging technologies have improved our ability to extend the rate of resection while minimizing the risk of inducing new neurologic deficits, together referred to as the “onco-functional balance.” However, despite the common utilization of invasive techniques such as cortical mapping to identify eloquent tissue responsible for language and motor functions, glioma patients continue to present post-operatively with poor cognitive morbidity in higher-order functions. Such observations are likely related to the difficulty in interpreting the highly-dimensional information these technologies present to us regarding cognition in addition to our classically poor understanding of the functional and structural neuroanatomy underlying complex higher-order cognitive functions. Furthermore, reduction of the brain into isolated cortical regions without consideration of the complex, interacting brain networks which these regions function within to subserve higher-order cognition inherently prevents our successful navigation of true eloquent and non-eloquent cerebrum. Fortunately, recent large-scale movements in the neuroscience community, such as the Human Connectome Project (HCP), have provided updated neural data detailing the many intricate macroscopic connections between cortical regions which integrate and process the information underlying complex human behavior within a brain “connectome.” Connectomic data can provide us better maps on how to understand convoluted cortical and subcortical relationships between tumor and human cerebrum such that neurosurgeons can begin to make more informed decisions during surgery to maximize the onco-functional balance. However, connectome-based neurosurgery and related applications for neurorehabilitation are relatively nascent and require further work moving forward to optimize our ability to add highly valuable connectomic data to our surgical armamentarium. In this manuscript, we review four concepts with detailed examples which will help us better understand post-operative cognitive outcomes and provide a guide for how to utilize connectomics to reduce cognitive morbidity following cerebral surgery.

Association Between Body Mass Index with Cognitive Function and Activities of Daily Living In Elderly: A Cross-Sectional Study

Background: Higher BMI has been often attributed with decline in cognitive function, mortality, and morbidity in elderly. However, few studies have reported high BMI as protective towards cognition and Activities of Daily Living (ADL). Accurate quantification of the role of BMI in the incidence of cognition and performance is desirable in the face of the increasing prevalence of individuals with overweight and obesity and prolonged life span in the population. This study aimed to investigate the association of BMI with cognition and ADL in community living elderly. Method: A cross sectional study was conducted among community living elderly. BMI and KATZ index scores were recorded from the respondents. Data were analyzed using SPSS version and a p value of less than 0.05 was considered statistically significant. Results: A total of 53 respondents enrolled in this study and was predominated by (54.7%) males and (45.30%) females. Karl Pearson correlation coefficient test found a positive correlation (r= 0.33) between BMI and Cognition and was found to be statistically significant (p&lt;0.05). Also, it was observed that moderately positive correlation exists between BMI and ADL (r =0.64) and was found to be statistically very highly significant (p&lt;0.001) Conclusion: This study concluded that among elderly, higher BMI values were associated with better performance in daily activities and lower cognitive impairment. KEY WORDS: Elderly, Body mass index, Activities of Daily Living, Cognition.

Brain injury in preterm infants with surgical necrotizing enterocolitis: clinical and bowel pathological correlates.

The objective of this study was to determine the risk factors and outcomes of white matter brain injury (WMBI) on magnetic resonance imaging (MRI) at term-equivalent age in infants with surgical necrotizing enterocolitis (NEC). This retrospective study compared clinical/pathological information between infants with and those without WMBI. Out of 69 infants with surgical NEC, 17 (24.6%) had mild WMBI, 13 (18.8%) had moderate WMBI, and six (8.7%) had severe WMBI on the brain MRI. Several clinical factors (gestational age, more red blood cell (RBC) transfusions before NEC onset, pneumoperitoneum, earlier NEC onset age, postoperative ileus, acute kidney injury (AKI) by serum creatinine, postnatal steroids, hospital stay) and histopathological findings (necrosis, hemorrhage) had univariate associations with WMBI. Associations with RBC transfusion (odds ratio (OR) 23.6 [95% confidence interval (CI): 4.73-117.97]; p = 0.0001), age at NEC onset (OR 0.30 [95%CI: 0.11-0.84]; p = 0.021), necrosis (OR 0.10 [95%CI: 0.01-0.90]; p = 0.040), and bowel hemorrhage (OR 7.79 [95%CI: 2.19-27.72]; p = 0.002) persisted in multivariable association with grade 3-4 WMBI. The infants with WMBI had lower mean motor, cognitive, language scores, and higher ophthalmic morbidity at 2 years of age. The WMBI was most likely associated with earlier NEC onset, higher RBC transfusions, and less necrosis and greater hemorrhage lesions on intestinal pathology in preterm infants with surgical NEC. In preterm infants with surgical NEC, brain MRI showed injury in the white matter in 52%, gray matter in 10%, and cerebellar region in 30%. Preterm infants with severe WMBI (grade 3-4) had less necrosis and greater hemorrhagic lesions on histopathology of the bowel. Preterm infants with WMBI were more likely to have a more severe postoperative course, AKI, and longer length of hospitalization. Neuroprotective strategies to prevent brain injury in preterm infants with surgical NEC are needed with the goal of improving the neurodevelopmental outcomes.

591 Sleep disturbances and executive function outcomes after critical care hospitalization in children with acquired brain injury

Abstract Introduction Annually, over 60,000 children require critical care admission for acquired brain injury (ABI) in the US, and many face long-term cognitive morbidity. Over 50% of these children also develop sleep/wake disturbances (SWD). Given the importance of sleep to brain development and healing after injury, we hypothesized SWD in children after ABI would portend worse cognitive outcomes in domains of executive function. Methods We performed a prospective observational study of N=80 children aged 6–18 years with ABI evaluated 1–3 months after critical care hospitalization. SWD were evaluated using the Sleep Disturbances Scale for Children (SDSC). The primary outcome was the Behavior Rating Inventory of Executive Function, 2nd Edition (BRIEF-2) Global Executive Composite (GEC; an age and gender adjusted T-score). Secondary cognitive outcomes included age adjusted scaled scores (ss) from the Delis Kaplan Executive Function System (DKEFS), Wechsler Intelligence Scale for Children, 5th Edition (WISC-V), and Children’s Memory Scale (CMS). Relationships between the SDSC and cognitive measures were evaluated using Spearman correlation (rs). Multiple linear regression evaluated associations between SWD and GEC T-scores controlling for patient and ABI characteristics. Results Sixty-five (81%) eligible children completed evaluation, and 48% had clinically significant SWD (total SDSC ≥39). Significant correlation (p&amp;lt;0.05) was found between the SDSC total score and worse GEC T-score (rs=0.60), and worse ss for CMS numbers forward (rs= -0.39), WISC-V coding (rs=-0.36), DKEFS number letter switching total time (rs=-0.38), and DKEFS category fluency (rs=-0.43). Presence of SWD was significantly associated with a full standard deviation worsening in the GEC T-score (β-coefficient= 10.2, 95% Confidence Interval=1.0–19.3) when controlling for age, race, gender, admission Glasgow Coma Scale, critical care intervention, and chronic comorbidities. Conclusion Children with ABI requiring critical care have high rates of SWD after discharge that are associated with significantly worse executive function outcomes in overall function (BRIEF-2 GEC) and direct objective assessments (DKEFS, WISC-V, CMS) evaluating aspects of executive functioning including attention, processing speed, cognitive flexibility, and working memory. SWD may serve as a modifiable target to improve cognitive outcomes in this vulnerable pediatric population.

Employment status monitoring in an Argentinian population of patients with multiple sclerosis: Particularities of a developing country.

Multiple sclerosis (MS) is a neurological chronic disease that causes a number of physical, cognitive and emotional symptoms. The identification of these factors will allow mitigating unemployment and improve quality of life of patients. The Buffalo Vocational Monitoring Survey (BVMS) is a tool to characterize Work-Challenged patients. To describe and analyze BVMS data in people with multiple sclerosis (PwMS) from Argentina. To study the association with physical, cognitive and psychiatric morbidity in employed patients, comparing the performance of MS Work-Challenged and MS Work-Stable patients, with and without accommodations. 119 MS patients were administered the Argentina adaptation of the BVMS, and completed measures of physical disability, fatigue, depression, cognitive processing speed, memory and verbal fluency. 65.54% of the patients were employed and 19.32% were unemployed, the remaining having roles of housewife, students and disability retirees. Within the employed subgroup, 60.26% were working as employees and 39.74% were self-employed. Cognitive and clinical variables differentiate patients with and without negative events and accommodations (p > 0.05). This Spanish version BVMS is considered a new tool to monitor employment difficulties in Spanish-speaking MS patients. MS Work-Challenged had a higher depression, fatigue and worse performance in cognitive variables.

Reproduction-related cognitive processing and distress among young adult women: the role of personal breast cancer history

Breast cancer diagnosis can threaten fertility and biological motherhood in women of reproductive age due to the gonadotoxic effects of treatments. Much evidence documents these women fertility-related concerns and distress, but no study has attempted to understand how implicit cognitive processes can contribute to this maladjustment. In this research, we explored whether reproduction-related stimuli interfere with cognition among cancer survivors with infertility risk using an emotional Stroop task. Furthermore, we investigated the relationship between reproduction-related cognitive processing and psychological morbidity. Young cancer survivors aged 18-40years who received anticancer treatments and an age-matched non-cancer control group without known fertility problems were compared. Color-naming times and error rates were assessed. Participants in both groups were slower naming the color of reproduction-related words in comparison to unrelated negative valence words. Although in the same direction, this difference did not reach statistical significance for positive and neutral unrelated word lists. Further analysis suggested that biased attention toward reproduction-related information was associated with higher depression levels in young women with personal breast cancer history, but not in healthy women. These findings suggest that biased processing of reproduction-related cues might be a vulnerability factor after a breast cancer diagnosis. Additionally, this study puts in evidence the potential usefulness of using experimental tasks to investigate attentional bias in a context where fertility is at risk.

Bridging the Gap between Neurology and Psychiatry- Psychiatric Symptoms in the course of Neurodegenerative Disorders

It is increasingly recognized that there is significant heterogeneity in phenotype and clinical trajectories in Alzheimer's disease as well as Lewy Body and Vascular dementia. Relatively common neurodegenerative disorder, Lewy Body Dementia (LBD) presents with psychiatric features. Mood disorders are common and often precede core symptoms of LBD. Patient with LBD especially early in the course of disease are at increased risk for suicide. Psychosis is one of the most debilitating symptoms of LBD as it is an independent risk factor for nursing home placements, increased caregiver distress and mortality. Visual hallucinations are the most common psychotic manifestation in LBD. Auditory, olfactory, tactile and gustatory hallucinations and delusions are less frequently found. Global cognitive deficits including attention, frontal executive dysfunction, visuospatial abnormalities, language and verbal memory were associated with the presence of psychosis in Lewy Body Dementia. Glucocerebrosidase gene (GBA) mutations and polymorphisms found to be associated with LBD. Up to 25% of Alzheimer's disease (AD) cases do not show the typical neuropathology. Subtypes and atypical non-amnestic AD presentations have been formalized in the International Working Group (IWG) clinical diagnosis criteria. Frontal signs and symptoms are often seen in Alzheimer's disease especially in patients with early onset. In those clinical situations differential diagnosis especially distunguising between Clinical diagnosis of atypical AD has significantly been improved by the availability of biomarkers, including cerebrospinal fluid levels of Aβ42, total tau and phosphorylated tau181. MRI volumetric estimation of hippocampal and medial temporal atrophy, and amyloid brain PET imaging. We will review atypical forms of AD from these varied perspectives to help improve diagnostic confidence among clinicians. Cerebral amyloid angiopathy (CAA) is a highly prevalent pathologic finding in the elderly contributing to cognitive loss, neuropsychiatric symptoms and morbidity. It is characterized by predominantly vascular deposition of beta amyloid protein Its prevalence varies across different populations. Initially conceptualized as vascular dementia syndrome CAA was proved to overlap with AD pathology and is thought to affect over 80% of AD patients. Lobar intracerebral hemorrhage and infarction are the well-known striking clinical manifestations, but CAA has multiple other clinical phenotypes: Inflammatory disease in the form of vasculitis known as amyloid beta related angiitis (ABRA) and inflammatory leukoencephalopathy, also known as CAA related inflammation (CAA-RI). Due to multiple clinical phenotypes CAA remains clinically underdiagnosed and underreported especially in elderly with dementia and other psychiatric symptoms. The underlying pathophysiological mechanism for the spectrum of CAA will be discussed.

Associations between Early Psychosocial Deprivation, Cognitive and Psychiatric Morbidity, and Risk-taking Behavior in Adolescence

ABSTRACT Objective Early psychosocial deprivation increases the risk of later cognitive and psychiatric problems, but not all deprived children show these difficulties. Here, we examine the extent to which psychosocial deprivation increases the risk of later cognitive and psychiatric difficulties and the downstream consequences of this for risk-taking behavior in adolescence. Method Children abandoned to institutions early in life were randomly assigned to care-as-usual or a foster care intervention during infancy. A separate group of never-institutionalized children was recruited as a comparison sample. The current follow-up study included 165 children (51% female), 113 with a history of institutionalization and 52 with no such history. At age 12, caregivers reported on children’s psychiatric difficulties, and their IQ was assessed by standardized testing. At 16 years, risk-taking behavior was assessed from youth self-reports. Results Latent profile analysis revealed three subgroups of children with varying levels of cognitive and psychiatric difficulties: Low-Morbidity (n = 104, 62.7%), Medium-Morbidity (n = 46, 27.9%), and High-Morbidity (n = 15, 9.4%). Nearly half of the institutionalized children belonged to the High- or Medium-Morbidity subgroups; and institutionally-reared children were significantly more likely to belong to one of these profiles than never-institutionalized children. Compared to the Low-Morbidity subgroup, membership in the Medium-Morbidity profile was associated with higher levels of risk-taking behavior at age 16 years. Conclusions Children who experience psychosocial deprivation are considerably more likely to present with elevated cognitive and psychiatric difficulties in early adolescence and, for some children, this elevation is linked to heightened risk-taking behavior in later adolescence.

Psychiatric and Cognitive Morbidity Following Moderate and Severe SARS-CoV-2 Infection: A Cohort Study

Background: Recent studies indicate that psychiatric and neurocognitive symptoms are frequent after Coronavirus Disease-2019 (COVID-19). The present study aims to investigate the occurrence of psychiatric and cognitive impairments in a cohort of survivors from moderate or severe forms of COVID-19.Methods: 425 adults (mean age 55.7 years) were assessed 6 to 9 months after hospital discharge with a structured psychiatric interview (Clinical Interview Schedule, CIS-R) and a combination of psychometric tests. Cognitive state was examined with a subjective memory complaint scale and screening tests. A large, multidisciplinary, set of clinical data depicting the acute phase of the disease, along with relevant psychosocial variables, were used to predict psychiatric and cognitive outcomes using the ‘Least Absolute Shrinkage and Selection Operator’ (LASSO) method.Outcomes: CIS-R diagnoses of ‘depression’, ‘generalized anxiety disorder’ and ‘post-traumatic stress disorder’ were established respectively in 8%, 15.5% and 13.6% of the sample. Memory decline was reported by 51.1% of the patients. Psychiatric or cognitive outcomes were not predicted by any clinical variables related to the severity of acute-phase disease, nor by disease-related psychosocial stressors. Rather, depression and anxiety were only predicted by current frailty and worse general health status.Interpretation: Using a structured psychiatric interview and an objective assessment of cognitive state, we found high rates of psychiatric and cognitive morbidity in the long-term outcome after moderate or severe COVID-19. The lack of associations of previous medical or psychosocial factors with these diagnoses suggests a direct, disease-related, mechanism in the pathophysiology of COVID-19 related psychiatric and cognitive impairments.Funding: This work was partially supported by donations from the general public under the HC-COMVIDA crowdfunding scheme (https://viralcure.org/c/hc) and the Fundação Faculdade de Medicina (ALA).

Social Isolation and Loneliness: Develop a More Robust Evidence Base

This paper reviews the evidence base for the health impacts of SIL on older adults, the risk factors, and the potential moderators and mediators of those relationships. Substantial evidence indicates that SIL are associated with physical, cognitive, and psychological morbidity; health-related behaviors; and health-related quality of life. Social isolation in particular is associated with a significantly increased risk of premature mortality from all causes. The evidence base for interventions in the clinical setting is also reviewed. Finally, the report’s specific recommendations are discussed, including the need for basic science research, increased funding, key elements in the design and evaluation of interventions, and gap areas (including trends among current younger adults and approaches for specific understudied groups of at-risk older adults). Part of a symposium sponsored by Loneliness and Social Isolation Interest Group.

QOL-38. USE OF COMPUTERIZED NEUROPSYCHOLOGICAL MEASURES TO ASSESS COGNITIVE MORBIDITY IN SURVIVORS OF CHILDHOOD BRAIN TUMORS

Treatment of central nervous system (CNS) tumors in pediatric populations is associated with significant cognitive morbidity. Documentation of neuropsychological deficits is vital to treatment and educational planning. We investigated the feasibility and utility of a computerized neuropsychological measure (NIH Toolbox Cognitive Battery) in differentiating individuals who received tumor treatment from healthy controls. Participants included pediatric CNS tumor survivors (N = 85; Mean Age = 13.47; SD = 4.76) at least 1-year post-completion of treatment and healthy sibling controls (N = 20; Mean Age = 10.2; SD = 3.21) who completed the NIH Toolbox. Ninety-eight percent of the participants enrolled completed the computerized tasks. The overall logistical regression model, with NIH Toolbox tests as predictors, was statistically significant [χ2 (7, N = 105) = 26.176; p < .001] and improved correct group classification from 81% to 82.9%. Picture Sequencing (β = -0.059; Wald = 6.942; p = .008) and Flanker (β = -0.083; Wald = 7.473; p = .006) were both statistically significant and negatively predictive of membership in the treatment group. For each 1 unit increase in standard score on measures of working memory and inhibition, odds of membership in the treatment group decreased by 6.2% and 8.7%, respectively. Consistent with the literature, worse performance on computerized measures of cognitive functioning mediated by executive functioning was correlated with a history of brain tumor treatment. Further investigation will focus on comparing computerized neuropsychological tools to traditional comprehensive neuropsychological evaluations and clarifying the trajectory of these deficits across recovery.

Patterns of informal family care during acute hospitalization of older adults from different ethno-cultural groups in Israel

IntroductionInformal caregiving during hospitalization of older adults is significantly related to hospital processes and patient outcomes. Studies in home settings demonstrate that ethno-cultural background is related to various aspects of informal caregiving; however, this association in the hospital setting is insufficiently researched.ObjectivesOur study explore potential differences between ethno-cultural groups in the amount and kind of informal support they provide for older adults during hospitalization.MethodsThis research is a secondary data analysis of two cohort studies conducted in Israeli hospitals. Hospitalized older adults are divided into three groups: Israeli-born and veteran immigrant Jews, Arabs, and Jewish immigrants from the Former Soviet Union (FSU). Duration of caregiver visit, presence in hospital during night hours, type of support (using the Informal Caregiving for Hospitalized Older Adults scale) are assessed during hospitalization. Results are controlled by background parameters including functional Modified Barthel Index (MBI) and cognitive Short Portable Mental Status Questionnaire (SPMSQ) status, chronic morbidity (Charlson), and demographic characteristics.ResultsInformal caregivers of “FSU immigrants” stay fewer hours during the day in both cohorts, and provide less supervision of medical care in Study 2, than caregivers in the two other groups. Findings from Study 1 also suggest that informal caregivers of “Arab” older adults are more likely to stay during the night than caregivers in the two other groups.ConclusionsEthno-cultural groups differ in their patterns of caregiving of older adults during hospitalization. Health care professionals should be aware of these patterns and the cultural norms that are related to caregiving practices for better cooperation between informal and formal caregivers of older adults.

Adherence to the Mediterranean Diet and Physical Resilience in Older Adults: The Seniors-ENRICA Cohort.

No prior studies have studied the association between diet and physical resilience, thus our aim was to assess the association between the adherence to the Mediterranean diet and other healthy dietary patterns and physical resilience, assessed empirically as a trajectory through exposure to chronic and acute stressors, in older adults participating in the Seniors-ENRICA (The Study on Nutrition and Cardiovascular Risk in Spain) cohort. Data were assessed from 1301 individuals aged 60 and older, participating in the ENRICA prospective cohort study and recruited in 2008-2010 and followed up to 2012 (trial registration: NCT02804672). A Mediterranean Diet Adherence Screener score and the Alternate Healthy Eating Index 2010 were derived at baseline from a validated diet history. Health status was assessed at baseline and at the end of follow-up with a 52-item health Deficit Accumulation Index (DAI) including 4 domains (physical and cognitive function, mental health, self-rated health/vitality, and morbidity); higher DAI values indicate worse health. Physical resilience was defined as accumulating fewer health deficits than the expected age-related increase in DAI over follow-up, despite exposure to chronic and acute stressors. Over a 3.2-year follow-up, 610 individuals showed physical resilience. In multivariate analyses, the odds ratio (95% confidence interval) of physical resilience for the highest versus lowest tertile (lowest adherence) of the Mediterranean Diet Adherence Screener score was 1.47 (1.10-1.98). The association held for those maintaining or improving the DAI over follow-up (over-resilience): 1.58 (1.10-2.26). Results were consistent in those with unintentional weight loss (2.21 [1.10-4.88]) or hospitalization (2.32 [1.18, 4.57]) as acute stressors. In older adults, a higher adherence to the Mediterranean diet is associated with a greater likelihood of physical resilience.
