The Ecological and Construct Validity of a Newly Developed Measure of Executive Function: The Virtual Library Task

Abstract Virtual reality (VR) assessment paradigms have the potential to address the limited ecological validity of pen and paper measures of executive function (EF) and the pragmatic and reliability issues associated with functional measures. To investigate the ecological validity and construct validity of a newly developed VR measure of EF, the Virtual Library Task (VLT); a real life analogous task—the Real Library Task (RLT); and five neuropsychological measures of EF were administered to 30 patients with traumatic brain injury (TBI) and 30 healthy Controls. Significant others for each participant also completed the Dysexecutive Questionnaire (DEX), which is a behavioral rating scale of everyday EF. Performances on the VLT and the RLT were significantly positively correlated indicating that VR performance is similar to real world performance. The TBI group performed significantly worse than the Control group on the VLT and the Modified Six Elements Test (MSET) but the other four neuropsychological measures of EF failed to differentiate the groups. Both the MSET and the VLT significantly predicted everyday EF suggesting that they are both ecologically valid tools for the assessment of EF. The VLT has the advantage over the MSET of providing objective measurement of individual components of EF. (JINS, 2012, 18, 440–450)
More than Intelligence: Distinct Cognitive/Behavioral Clusters Linked to Adaptive Dysfunction in Children

Abstract Impairments in adaptive functioning are frequently associated with intellectual disability (ID); however, adaptive dysfunction can be seen in many individuals with a variety of neurological conditions without ID. The extent to which other variables may be associated with adaptive dysfunction is unclear. In a mixed clinical sample of children (n = 348) consecutively referred for neuropsychological evaluation, the majority were rated as showing weak adaptive skills (ABAS-II, >1 SD below the mean; 71%), with a substantial proportion evidencing frank impairment (>2 SD below the mean, 45%). We examined patterns of scores on measures of intelligence (WISC-IV) and behavioral/affective dysregulation (BRIEF and BASC-2). Using hierarchical cluster analysis, a four cluster model yielded the most appropriate fit and adaptive functioning was subsequently examined across clusters. As expected, adaptive functioning was most intact in the cluster characterized by average IQ and minimal behavioral dysregulation. Other clusters were marked by adaptive dysfunction and distinguished by sub-average intellectual functioning and varying behavioral/emotional dysregulation. In contrast to traditional views associating low IQ with adaptive dysfunction, adaptive impairment was comparable between the cluster characterized by low intelligence and the cluster with average intelligence but significant behavioral dysregulation. These data suggest that adaptive functioning should be considered across various cognitive/behavioral conditions. (JINS, 2013, 19, 1–9)
Integrated Management of Depression in the Elderly: Contributors

Depression is one of the most common mental health problems facing older people, and it is often unrecognised and usually under-treated. Integrated Management of Depression in the Elderly provides an entirely new approach to understanding late-life depression, by using a series of case studies with commentaries from practitioners internationally. The book covers the epidemiology, presentation and diagnosis of depression in older people and outlines current evidence for effective management drawing on recently published work. The substantive part of the book presents ten case studies of increasing complexity, each case has a commentary from a primary care clinician and a health or social care professional, to outline how professionals should work together to manage the patient within their community. Contributions from world experts give the book an international appeal. It will appeal to a wide audience of health and social care professionals together with psychiatrists-in-training.
Let's Face It: Facial Emotion Processing Is Impaired in Bipolar Disorder

Abstract Patients with bipolar disorder (BD) have difficulty in recognizing and discriminating facial emotions. However, beyond this broad finding, existing literature is equivocal about the specific nature of impairments, and progress toward adequately profiling facial emotion processing in BD is hampered by methodological inconsistencies. The current study aimed to advance the literature by comparing 50 BD patients and 52 controls on a series of facial emotion processing tasks. Results indicated that patients with BD had a small, yet consistent impairment in emotion processing overall. This impairment did not vary as a function of specific emotions, tasks, or intensities between groups, and was not influenced by current mood state. These results suggest that past inconsistencies in the literature are unlikely to be attributable to task related artifacts influencing the estimation of an effect. These findings add to our understanding of social cognition in BD, and have important implications for clinicians treating patients with the disorder. (JINS, 2014, 20, 1–9)
Community Outcome in Cognitively Normal Schizophrenia Patients

Abstract Recent reports suggest that cognition is relatively preserved in some schizophrenia patients. However, little is known about the functional advantage these patients may demonstrate. The purpose of this study was to identify cognitively normal patients with a recently developed test battery and to determine the functional benefit of this normality relative to cognitively impaired patients. Average-range cognitive ability was defined by the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) composite score (T≥40) and applied to 100 patients with schizophrenia or schizoaffective disorder and to 81 non-psychiatric research participants. With group assignment adjusted for demographic variables, this procedure yielded 14 cognitively normal patients, 21 cognitively impaired patients, and 21 healthy adults with normal-range MCCB scores. Cognitively normal patients were indistinguishable from controls across all MCCB scales. Furthermore, their performance was superior to impaired patients on all scales except Social Cognition. Cognitively normal patients were also superior to impaired patients on a summary index of simulated life skills and functional competence. Nevertheless, both patient groups were equally disadvantaged relative to controls in independent community living. These findings suggest that normal-range cognition exists in schizophrenia, but fails to translate into enhanced community outcome. (JINS, 2014, 20, 1–7)
Factors Associated with Preoperative Magnetic Resonance Imaging Use among Medicare Beneficiaries with Nonmetastatic Breast Cancer

Preoperative breast magnetic resonance imaging (MRI) use among Medicare beneficiaries with breast cancer has substantially increased from 2005 to 2009. We sought to identify factors associated with preoperative breast MRI use among women diagnosed with ductal carcinoma in situ (DCIS) or stage I–III invasive breast cancer (IBC). Using Surveillance, Epidemiology, and End Results and Medicare data from 2005 to 2009 we identified women ages 66 and older with DCIS or stage I–III IBC who underwent breast‐conserving surgery or mastectomy. We compared preoperative breast MRI use by patient, tumor and hospital characteristics stratified by DCIS and IBC using multivariable logistic regression. From 2005 to 2009, preoperative breast MRI use increased from 5.9% to 22.4% of women diagnosed with DCIS and 7.0% to 24.3% of women diagnosed with IBC. Preoperative breast MRI use was more common among women who were younger, married, lived in higher median income zip codes and had no comorbidities. Among women with IBC, those with lobular disease, smaller tumors (<1 cm) and those with estrogen receptor negative tumors were more likely to receive preoperative breast MRI. Women with DCIS were more likely to receive preoperative MRI if tumors were larger (>2 cm). The likelihood of receiving preoperative breast MRI is similar for women diagnosed with DCIS and IBC. Use of MRI is more common in women with IBC for tumors that are lobular and smaller while for DCIS MRI is used for evaluation of larger lesions.
HIV Infection Is Associated with Attenuated Frontostriatal Intrinsic Connectivity: A Preliminary Study

Abstract HIV-associated cognitive impairments are prevalent, and are consistent with injury to both frontal cortical and subcortical regions of the brain. The current study aimed to assess the association of HIV infection with functional connections within the frontostriatal network, circuitry hypothesized to be highly vulnerable to HIV infection. Fifteen HIV-positive and 15 demographically matched control participants underwent 6 min of resting-state functional magnetic resonance imaging (RS-fMRI). Multivariate group comparisons of age-adjusted estimates of connectivity within the frontostriatal network were derived from BOLD data for dorsolateral prefrontal cortex (DLPFC), dorsal caudate and mediodorsal thalamic regions of interest. Whole-brain comparisons of group differences in frontostriatal connectivity were conducted, as were pairwise tests of connectivity associations with measures of global cognitive functioning and clinical and immunological characteristics (nadir and current CD4 count, duration of HIV infection, plasma HIV RNA). HIV – associated reductions in connectivity were observed between the DLPFC and the dorsal caudate, particularly in younger participants (<50 years, N=9). Seropositive participants also demonstrated reductions in dorsal caudate connectivity to frontal and parietal brain regions previously demonstrated to be functionally connected to the DLPFC. Cognitive impairment, but none of the assessed clinical/immunological variables, was also associated with reduced frontostriatal connectivity. In conclusion, our data indicate that HIV is associated with attenuated intrinsic frontostriatal connectivity. Intrinsic connectivity of this network may therefore serve as a marker of the deleterious effects of HIV infection on the brain, possibly via HIV-associated dopaminergic abnormalities. These findings warrant independent replication in larger studies. (JINS, 2015, 21, 1–11)
The Association of Satisfaction and Perceived Burden With Anxiety and Depression in Primary Caregivers of Dependent Elderly Relatives.

Some researchers have viewed caregiver burden and satisfaction as two ends of the same continuum rather than as independent aspects of the caregiving experience. We conducted a cross-sectional study of primary caregivers of dependent elderly relatives in Spain (N = 200; probabilistic sample), to determine whether satisfaction and perceived burden coexisted in caregivers, and whether these variables, considered separately and in combination, were associated with anxiety and depression, while controlling for objective aspects of care recipients' needs. Data on satisfaction with care, perceived burden, objective burden, anxiety, and depression were gathered in 2013 by interviews in caregivers' homes. Descriptive, bivariate, and multivariate analyses were performed. Of the 200 primary caregivers, 12.5% reported both high satisfaction with care and high perceived burden. Anxiety and depression levels were lower in caregivers with high satisfaction and low perceived burden than in those with low satisfaction and high burden or with high satisfaction and high burden. Our findings support the following conclusions: (1) Satisfaction may be experienced despite the presence of stressful factors; (2) the combination of high satisfaction and low burden might have protective effects on anxiety and depression in caregivers.
Cognitive Deficits Correlate with White Matter Deterioration in Spinocerebellar Ataxia Type 2

Abstract Objectives: The aim of this study was to explore the relationship between cognitive and white matter deterioration in a group of participants with spinocerebellar ataxia type 2 (SCA2). Methods: Fourteen genetically confirmed participants with SCA2 and 14 aged-matched controls participated in the study. Diffusion tensor imaging tract-based spatial statistics were performed to analyze structural white matter integrity. Significant group differences in the mean diffusivity were correlated with SCA2 cognitive deficits. Results: Our analysis revealed higher mean diffusivity in the SCA2 group in cerebellar white matter, medial lemniscus, and middle cerebellar peduncle, among other regions. Cognitive scores correlated with white matter mean diffusivity in the parahippocampal area, inferior frontal and supramarginal gyri and the stria terminalis. Conclusions: Our findings show significant correlations between white matter microstructural damage in key areas affected in SCA2 and cognitive deficits. These findings result in a more comprehensive understanding of the effect of the neurodegenerative process in people with SCA2. (JINS, 2016, 22, 486–491)
Systematic Review of Neuropsychological Rehabilitation for Prospective Memory Deficits as a Consequence of Acquired Brain Injury

Abstract Objectives: Prospective memory (PM) impairments are common following acquired brain injury (ABI). PM is the ability to keep a goal in mind for future action and interventions have the potential to increase independence. This review aimed to evaluate studies examining PM rehabilitation approaches in adults and children with ABI. Methods:Relevant literature was identified using PsycARTICLES (1894 to present), PsycINFO (1880 to present), the Cochrane Library (1972 to present), MEDLINE PubMed, reference lists from relevant journal articles, and searches of key journals. Literature searches were conducted using variants of the terms brain injury, stroke, encephalitis, meningitis, and tumor, combined with variants of the terms rehabilitation and prospective memory. Results: Of the 435 papers identified, 11 were included in the review. Findings demonstrated a variety of interventions to alleviate PM deficits, including compensatory strategies (e.g., external memory aids) that provide either content-specific or content-free cueing, and remediation strategies (e.g., meta-cognitive training programs) aimed at improving the self-monitoring of personal goals. Risk of bias for individual studies was considered and the strengths and limitations of each of the included studies and the review itself were discussed. Conclusions: Interventions used with adults can be effective; PM abilities can be improved by using simple reminder systems and performance can be generalized to facilitate everyday PM functioning. There is, however, a lack of research of PM interventions conducted with children with ABI, and pediatric interventions need to consider on-going cognitive maturation. (JINS, 2017, 23, 254–265)
Radioactive iodine studies in childhood hypothyroidism.

The usefulness of radioactive isotopes of iodine in the study of iodine metabolism has been demonstrated by several groups of workers. 1 They are of particular value in measuring the gross iodine metabolism of the thyroid in situ lb in normal persons and in patients whose thyroids need not be removed surgically. The studies reported in this paper, which were carried out with the cooperation of the department of pediatrics of the University of California Medical School, show that by the use of radioactive iodine certain aspects of the iodine metabolism in children with hypothyroidism can be examined. Ordinary, or stable, iodine and radioactive iodine are chemically and physiologically the same as long as the amount of radioiodine is less than that which produces physiologic changes by the action of its radiation. In these experiments, less than one-fiftieth the amount of radioiodine necessary to produce biologic changes was used. The
Dietary modification dampens liver inflammation and fibrosis in obesity‐related fatty liver disease

Background: Alms1 mutant (foz/foz) mice develop hyperphagic obesity, diabetes, metabolic syndrome, and fatty liver (steatosis). High‐fat (HF) feeding converts pathology from bland steatosis to nonalcoholic steatohepatitis (NASH) with fibrosis, which leads to cirrhosis in humans.
Eligibility of patients for minimally invasive breast cancer therapy based on MRI analysis of tumor proximity to skin and pectoral muscle

There is growing interest in minimally invasive breast cancer therapy. Eligibility of patients is, however, dependent on several factors related to the tumor and treatment technology. The aim of this study is to assess the proportion of patients eligible for minimally invasive breast cancer therapy for different safety and treatment margins based on breast tumor location. Patients with invasive ductal cancer were selected from the MARGINS cohort. Semiautomatic segmentation of tumor, skin, and pectoral muscle was performed in Magnetic Resonance images. Shortest distances of tumors to critical organs (ie, skin and pectoral muscle) were calculated. Proportions of eligible patients were determined for different safety and treatment margins. Three‐hundred‐forty‐eight patients with 351 tumors were included. If a 10 mm safety margin to skin and pectoral muscle is required without treatment margin, 72.3% of patients would be eligible for minimally invasive treatment. This proportion decreases to 45.9% for an additional treatment margin of 5 mm. Shortest distances between tumors and critical organs are larger in older patients and in patients with less aggressive tumor subtypes. If a 10 mm safety margin to skin and pectoral muscle is required, more than two‐thirds of patients would be eligible for minimally invasive breast cancer therapy.
Socio-spatial disparities of obesity among adults in the urban setting of Ouagadougou, Burkina Faso

Abstract Objectives To document the prevalence and the socio-spatial variations of obesity and to identify individual and household characteristics, lifestyles and dietary practices contributing to obesity and its socio-spatial distribution. Design Population-based cross-sectional survey. We selected 1570 households from four strata characterised as unstructured and low building-density (ULBD), unstructured and high building-density (UHBD), structured and low building-density (SLBD) and structured and high building-density (SHBD) areas. Structured areas are those that were allotted by the township authority (cadastral services), with public services; unstructured areas refer to those developed with no cadastral organisation. Setting Ouagadougou, the capital city of Burkina Faso. Subjects BMI was calculated in 2022 adults aged 35 years and above who were classified as obese when their BMI was ≥30 kg/m2. Obesity was investigated in relation to household and individual characteristics, lifestyles and dietary practices; adjusted odds ratios with 95 % confidence intervals were derived from a logistic regression model. Results The overall prevalence of obesity was 14·7 % (males 5·5 % and females 21·9 %). Age, gender, household equipment index, usual transport with motor vehicles and micronutrient-rich food consumption were associated with obesity. After adjustment for these factors, obesity remained associated with the area of residence: residents from SHBD areas were more likely to be obese than those from ULBD areas (OR = 1·41; 95 % CI 2·59,4·76). Conclusions Obesity in Ouagadougou is a preoccupant problem that calls for more consideration. Thorough investigation is needed to assess the environmental factors that contribute to the socio-spatial disparity of obesity.
Characteristics of high and low energy reporting teenagers and their relationship to low energy reporting mothers

Abstract Objective To describe the differences in socio-economic characteristics and body measurements between low, adequate and high energy reporting (LER, AER and HER) teenagers; furthermore, to investigate the relationship to misreporting mothers. Design Cross-sectional study. Habitual dietary intake was reported in a questionnaire. Classification into LER, AER and HER using the Goldberg equation within three activity groups based on physical activity questionnaire and calculated BMR. Setting Stockholm, Sweden. Subjects Four hundred and forty-one 16–17-year-old teenagers (57 % girls) and their mothers. Result Of the teenagers, 17–19 % were classified as HER, while 13–16 % as LER. There was a highly significant trend from HER to LER in BMI (P < 0·001) and body fat % (P < 0·001). There was also a trend in number of working hours of mother (P = 0·01), family income (P = 0·008) and number of siblings (among boys only) (P = 0·02), but not in educational level of either father or mother. HER teenagers were lean, had mothers working fewer hours with lower income and had siblings. It was more likely that an LER girl had an LER mother than an AER mother (OR = 3·32; P = 0·002). Conclusions The reasons for the high number of over-reporters could be many: misclassification due to growth, lacking established eating pattern due to young age or method-specific. Nevertheless, the inverted characteristic of HER compared to LER indicates that this is a specific group, worth further investigation.
A Numerical Method for Predicting Acoustical Wave Propagation in Open Spaces

We present a numerical methodology for evaluating wave propagation phenomena in two dimensions in the time domain with focus on the linear acoustic second-order wave equation. An outline of the higher-order compact discretization schemes followed by the time discretization technique is first presented. The method is completed with the addition of spatial filtering based on the same compact schemes' principles. The important role of boundary conditions is subsequently addressed. Two popular ways to truncate the computational domain in the near field are presented and compared here: first the formulation of “absorbing conditions” in the form of partial differential equations especially for the origin and second the construction of an absorbing layer surrounding the domain, in which waves (after they have exited the domain) are attenuated and decayed exponentially. Subsequently, the method is assessed by recalling three benchmark problems. In the first where a Gaussian pulse is generated and propagated in a 2D rectangular domain, the accuracy and absorbability of the boundary conditions are compared. In the second, a similar situation is investigated but under curvilinear coordinates and under the presence of a solid body which scatters the pulse. Finally the sound field inducted by the flow of corotating vortex pair is calculated and compared with the corresponding analytical solution.
A gene variant of PNPLA3, but not of APOC3, is associated with histological parameters of NAFLD in an obese population

Mechanisms explaining the relationship in non‐alcoholic fatty liver disease (NAFLD), obesity, and insulin resistance are poorly understood. A genetic basis has been suggested. We studied the association between the genes patatin‐like phospholipase domain‐containing protein 3 (PNPLA3) and apolipoprotein C3 (APOC3) and metabolic and histological parameters of NAFLD in obese patients.
