Abstract
STUDY OBJECTIVES People living with schizophrenia (PLWS) have increased physical comorbidities and premature mortality which may be linked to dysregulated rest-activity rhythms (RARs). This study aimed to compare RARs between PLWS and non-psychiatric comparison participants (NCs); examine the relationships of RARs with age, sleep, metabolic and physical health outcomes; and, among PLWS, relationships of RARs with illness-related factors. METHODS The study sample included 26 PLWS and 36 NCs, assessed with wrist-worn actigraphy to compute RAR variables and general sleep variables. Participants completed assessments for clinical symptoms, physical health, sleep quality, medication use, and assays for fasting glycosylated hemoglobin (HbA1c) levels. We examined group differences in RAR and sleep variables, relationships of RAR variables with metabolic and physical health measures, and, among PLWS, relationships between RAR variables and illness-related measures. RESULTS PLWS had significantly shorter active periods, lower relative amplitude, and lower mean activity during their most active 10 hours compared to the NCs (Cohen's d=.79, .58, and .62; respectively). PLWS had poorer sleep quality, greater mean percent sleep, less wake after sleep onset, and higher total sleep time (TST) variability compared to NCs. PLWS had higher rates of antidepressant, anxiolytic, and antipsychotic medication use compared to NCs, which may have impacted sleep quality and objective sleep measures. Across both groups, more fragmented and variable RARs were associated with higher HbA1c levels (ηp2=0.10) and worse physical health (ηp2=0.21). Among PLWS, RARs were correlated with TST (rs=.789, p<0.01) and percent sleep (rs=.509, p<0.05), but not with age, sleep quality, or other illness-related factors. CONCLUSIONS RARs provide unique information about sleep and activity for PLWS and have the potential for targeted interventions to improve metabolic health and mortality.

Abstract
Objective: Parental and other caregiving leave is important to postdoctoral fellows, yet there is no field-wide recommendation for leave policies among clinical neuropsychology postdoctoral training programs, which is of particular relevance given the two-year requirement for eligibility for board certification. The aims of this manuscript are to (a) discuss general guidelines and recommendations for leave policies, both informed by prior empirical evidence as well as relevant existing policy guidelines from various academic and healthcare organizations, and (b) use vignettes to provide possible solutions for potential leave scenarios. Method: A critical review of literature on family leave from public policy and political science, industrial-organizational psychology, academic medicine, and psychology was conducted and findings were synthesized. Results and Conclusions: Fellowship training programs are encouraged to adopt a competency-based model that permits flexibility in leave during training without necessarily requiring an extended end date. Programs should adopt clear policies and make this information readily available to trainees and think flexibly about training options that best meet the training needs and goals of each individual. We also encourage neuropsychologists at all levels to engage in advocacy for broader systemic supports of trainees seeking equitable family leave.

Abstract
INTRODUCTION Women's important roles within families which include modelling appropriate oral health behaviours require them to have good knowledge and positive attitude in oral health. This study determined knowledge and attitude towards children's oral health among first-time mothers and factors associated with the attributes. MATERIALS AND METHODS A total of 154 first-time mothers in the third trimester of pregnancy who attended two health clinics in the state of Sarawak, Malaysia for antenatal care participated in this cross-sectional study. A structured selfadministered questionnaire was used to measure the variables of interest. RESULTS Most mothers could correctly identify the aetiological factors of dental caries and strategies for preventing the disease in children. However, a substantial portion could not identify certain cariogenic and noncariogenic foods or drinks. Most pregnant women have appropriate attitudes towards children's oral health although some showed unfavourable attitude about care of primary teeth. Women who were older and had attended a talk on children's oral health were more likely to have higher mean knowledge score than their respective counterparts, and higher mean knowledge score was associated with higher mean attitude score. CONCLUSION Most first-time mothers in this study had correct knowledge and favourable attitude about children's oral health, although misunderstandings and misperceptions in several issues were also common. Significant association found between experience of attending oral health talk and oral health knowledge, and between oral health knowledge and attitude, substantiate the importance of an educational intervention program to optimise the mothers' roles in caries prevention in children.

Abstract
BACKGROUND AND OBJECTIVE In individuals experiencing homelessness, determinants of functional capacity (i.e. the ability to perform activities of daily living) are poorly understood. Identifying potentially modifiable correlates of functional capacity, such as cognitive abilities, may inform treatment targets to address independence and housing stability. This study aimed to identify the strongest neuropsychological predictors of variance in functional performance in 100 adults living in a homeless shelter. METHODS Participants completed a brief cognitive screening test, from which four composite scores were derived, as well as tests of processing speed, fluid reasoning, premorbid intellectual function, and performance-based functional capacity. We conducted a hierarchical linear regression to predict variance in functional capacity. RESULTS Beyond the impact of education and premorbid intellectual function, better memory and fluid reasoning predicted better functional performance. CONCLUSIONS Although our cross-sectional design does not permit causal inference, it is possible that interventions targeting memory and fluid reasoning may improve functional ability in individuals experiencing homelessness.

Abstract
OBJECTIVE To examine the relationship between neuropsychological functioning and performance-based functional capacity in veterans with a history of mild traumatic brain injury (mTBI), as well as the moderating effects of age and psychiatric symptoms on this relationship. SETTING Three Veterans Affairs medical centers. PARTICIPANTS One hundred nineteen Iraq/Afghanistan veterans with a history of mTBI and self-reported cognitive difficulties. DESIGN Cross-sectional, secondary data analysis of baseline measures in a randomized controlled trial. MAIN MEASURES The main outcome measure, functional capacity, was assessed using the objective and performance-based University of California San Diego Performance-based Skills Assessment-Brief. A global deficit score (GDS) was created as a composite score for performance on a battery of neuropsychological measures assessing domains of attention, processing speed, executive functioning, and verbal memory performance. Posttraumatic stress disorder (PTSD) symptom severity was assessed using the PTSD Checklist-Military Version, and depressive symptom severity was assessed using the Beck Depression Inventory, Second Edition. RESULTS Bivariate analyses indicated that worse neuropsychological performance (ie, higher GDS) and greater PTSD symptom severity were associated with worse communication abilities and worse overall functional capacity. Multiple linear regressions demonstrated that GDS and PTSD symptom severity explained 9% of the variance in communication and 10% of the variance in overall functional capacity; however, GDS emerged as the only significant predictor in both regressions. Age, PTSD, and depressive symptom severity did not moderate the relationship between GDS and overall functional capacity. Performance in the verbal learning and memory domain emerged as the strongest neuropsychological predictor of communication and overall functional capacity. CONCLUSIONS Worse neuropsychological functioning was moderately associated with worse performance-based functional capacity, even when accounting for PTSD symptom severity. Verbal learning and memory was the primary neuropsychological domain driving the relationship with functional capacity; improvement in verbal learning and memory may translate into improved functional capacity.

Abstract
INTRODUCTION Health literacy is an independent predictor of health outcomes, including health knowledge and behavior. This study determined the influence of oral health literacy on knowledge and attitude towards children's oral health among pregnant women. MATERIALS AND METHODS A total of 130 pregnant women (65 nulliparous and 65 primiparous or multiparous) attending Hospital Universiti Sains Malaysia for antenatal care who did not have any diagnosed cognitive disorders and could read and write in the Malay language participated in this crosssectional study. A structured self-administered questionnaire was used to measure knowledge and attitude towards children's oral health, and the Malay version of the Oral Health Literacy Instrument (OHLI-M) was used to assess the oral health literacy of the participants. RESULTS Multivariable linear regression analysis showed that older women and women with higher OHLI-M scores had higher mean knowledge scores than younger women (p=0.007) and women with lower OHLI-M scores (p=0.001), respectively. In addition, women with higher OHLI-M scores, women with higher mean knowledge scores, and women who had attended a talk about children's oral health were more likely to have higher mean attitude scores than women with lower OHLI-M scores (p=0.019), women with lower mean knowledge scores (p=0.006), and women who had never attended a talk about children's oral health (p=0.001). CONCLUSION Pregnant women's oral health literacy was positively associated with their oral health knowledge and attitude towards children's oral health. Strategies to improve the oral health literacy of pregnant women are indicated.

Abstract
Individuals with schizophrenia who have high negative symptoms are at high risk for poor functional outcomes. However, the determinants of psychosocial functioning in this group are not well understood. We aimed to examine modifiable predictors of both objective, performance-based functional capacity and social skills, and self-reported functioning in individuals with schizophrenia and schizoaffective disorder and high negative symptoms. Fifty-five adults with moderate-to-severe negative symptoms were administered measures of neuropsychological performance, performance-based functional capacity and social competence, self-reported functioning, psychiatric symptom severity, defeatist/asocial beliefs, and intrinsic motivation. In the context of multiple significant predictor variables identified through bivariate correlations, multiple regression models showed that neuropsychological performance was the only significant predictor of performance-based functional capacity; neuropsychological performance and motivation/pleasure negative symptoms were significant predictors of performance-based social competence. For two different measures of self-reported functioning, intrinsic motivation, asocial beliefs, and diminished expression emerged as significant predictors. Neurocognitive ability was a better predictor of performance-based functional skills whereas motivation and beliefs more strongly predicted self-reported real-world functioning. The findings of this study suggest a complex picture of predictors of performance-based functional capacity (objective neuropsychological functioning) and self-reported functioning (motivation and beliefs), underscoring the clinical and scientific utility of including both self-reported and objective measures of functioning to identify treatment approach. Individuals with high negative symptoms and a cognitive/functional skills deficit may benefit from interventions such as cognitive remediation or skills training, whereas individuals with motivational difficulties may benefit from treatments such as cognitive behavioral therapy.

Abstract
OBJECTIVE The current cross-sectional study examined cognition and performance-based functional abilities in a continuing care senior housing community (CCSHC) that is comparable to other CCSHCs in the US with respect to residents' demographic characteristics. METHOD Participants were 110 older adult residents of the independent living unit. We assessed sociodemographics, mental health, neurocognitive functioning, and functional capacity. RESULTS Compared to normative samples, participants performed at or above expectations in terms of premorbid functioning, attention span and working memory, processing speed, timed set-shifting, inhibitory control, and confrontation naming. They performed below expectation in verbal fluency and verbal and visual learning and memory, with impairment rates [31.4% (>1 SD below the mean) and 18.49% (>1.5 SD below the mean)] well above the general population (16% and 7%, respectively). Within the cognitive test battery, two tests of delayed memory were most predictive of a global deficit score. Most cognitive test scores correlated with performance-based functional capacity. CONCLUSIONS Overall, results suggest that a subset of older adults in the independent living sector of CCSHCs are cognitively and functionally impaired and are at risk for future dementia. Results also argue for the inclusion of memory tests in abbreviated screening batteries in this population. We suggest that CCSHCs implement regular cognitive screening procedures to identify and triage those older adults who could benefit from interventions and, potentially, a transition to a higher level of care.

Abstract
OBJECTIVE Negative symptoms and cognitive impairment in schizophrenia (SZ) remain unmet treatment needs as they are highly prevalent, associated with poor functional outcomes, and resistant to pharmacologic treatment. The current pilot randomized controlled trial examined the efficacy of an integrated Cognitive-Behavioral Social Skills Training and Compensatory Cognitive Training (CBSST-CCT) intervention compared to Goal-focused Supportive Contact (SC) on negative symptoms and cognitive performance. METHODS Fifty-five adults with SZ or schizoaffective disorder with moderate-to-severe negative symptoms were randomized to receive 25 twice-weekly, 1-h manualized group sessions (12.5 weeks total duration) of either CBSST-CCT or SC delivered by master's level clinicians in five community settings. Assessments of negative symptom severity (primary outcomes) and neuropsychological performance, functional capacity, social skills performance, and self-reported functional ability/everyday functioning, psychiatric symptom severity, and motivation (secondary outcomes) were administered at baseline, mid-treatment, post-treatment, and 6-month follow-up. RESULTS Mixed-effects models using baseline, mid-treatment, and post-treatment data demonstrated significant CBSST-CCT-associated effects on negative symptom severity, as assessed by the Scale for the Assessment of Negative Symptoms (p = .049, r = 0.22), with improvements in diminished motivation driving this effect (p = .037, r = 0.24). The CBSST-CCT group also demonstrated improved verbal learning compared to SC participants (p = .026, r = 0.36). The effects of CBSST-CCT appeared to be durable at 6-month follow-up. CONCLUSIONS CBSST-CCT improved negative symptom severity and verbal learning in high-negative-symptom individuals relative to SC. CBSST-CCT warrants larger investigations to examine its efficacy in treating negative symptoms, along with other symptoms, cognition, and, ultimately, real-world functional outcomes. Clinical Trial registration number NCT02170051.

Abstract
Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup of most crops. Narrowed genetic makeup of these crops has made them vulnerable towards disease and insect epidemics. For sustainable crop production, genetic variability of these crops must be broadened against various biotic and abiotic stresses. One of the ways to widen genetic configuration of these crops is to identify novel additional sources of durable resistance. In this regard crops wild relatives are providing valuable sources of allelic diversity towards various biotic, abiotic stress tolerance and quality components. For incorporating novel variability from wild relative's wide hybridization technique has become a promising breeding method. For this purpose, wheat-Th. bessarabicum amphiploid, addition and translocation lines have been screened in field and screen house conditions to get novel sources of yellow rust and Karnal bunt resistant. Stripe rust screening under field conditions has revealed addition lines 4JJ and 6JJ as resistant to moderately resistant while addition lines 3JJ, 5JJ, 7JJ and translocation lines Tr-3, Tr-6 as moderately resistant wheat-Thinopyrum-bessarabicum genetic stock. Karnal bunt screening depicted addition lines 5JJ and 4JJ as highly resistant genetic stock. These genetic stocks may be used to introgression novel stripe rust and Karnal bunt resistance from the tertiary gene pool into susceptible wheat backgrounds.

Abstract
We investigated subjective cognitive complaints (SCCs), as well as physical and mental health factors, in adults and older adults. U.S. residents (N = 2,962) were recruited via the Amazon Mechanical Turk platform and completed a 90-item survey. Overall, 493/1930 (25.5%) of younger adults and 278/1032 (26.9%) of older adults endorsed SCCs. Analyses revealed worse physical and mental health characteristics in the SCC+ compared to the SCC- group, with primarily medium (Cohen's d = 0.50) to large (0.80) effect sizes. Age did not moderate relationships between SCCs and physical/mental health. Results suggest that SCCs are associated with a diverse set of negative health characteristics such as poor sleep and high body mass index, and lower levels of positive factors, including happiness and wisdom. Effect sizes of psychological correlates were at least as large as those of physical correlates, indicating that mental health is critical to consider when evaluating SCCs.

Abstract
OBJECTIVE Rapid Eye Movement Sleep Behavior Disorder (RBD) is common in Parkinson's Disease (PD) and is associated with cognitive impairment; however, the majority of the evidence on the impact of RBD on multidomain cognitive batteries in PD is cross-sectional. This study evaluated the longitudinal impact of probable RBD (pRBD) on cognitive, psychiatric, and functional outcomes in people with PD. METHOD Case-control study. A total of 65 people with PD completed the study protocol at baseline and 16-to-47-month follow-up. Participants were classified as pRBD+ (n = 25) or pRBD- (n = 40) based on an established cutoff of 6 on the RBD Sleep Questionnaire (RBDSQ). Participants also completed a) comprehensive cognitive testing, b) self-report measures of depression, anxiety, and apathy, and c) performance-based and other-report forms of instrumental activities of daily living. RESULTS Baseline mean age was 67.8 (SD = 8.1; range = 45-86) and baseline mean years of education was 16.4 (SD = 2.1; range = 12-20). The two groups did not differ on measured demographic characteristics. Baseline mean T-scores for cognitive tests were in the average range (46-55). Hierarchical linear models tested group differences in cognitive and functional decline from baseline to follow-up, controlling for appropriate demographic and psychiatric variables. Compared to the pRBD- group, pRBD+ participants showed greater decline in attention/working memory (r = -0.31; p = 0.01) and UPSA financial skills (r = -0.31; p = 0.01). No other group differences approached significance. CONCLUSIONS RBD may differentially affect attention/working memory and financial abilities in PD. Results underscore the importance of regular RBD screening in older adults with PD in order to triage symptomatic patients to appropriate cognitive and medical interventions.

Abstract
OBJECTIVE This study examined rates of objective cognitive and functional impairments and associations between cognitive performance and performance-based functional capacity in a well-characterized sample of adults experiencing homelessness. METHODS One hundred participants completed a brief neuropsychological and functional capacity assessment and self-report questionnaires. Cognitive impairment rates were determined by comparing mean scores with published normative data, as well as by examining frequency of scores >1 SD below the mean. Pearson correlations were used to examine associations between cognitive and functional capacities. RESULTS Overall, 65% of the study participants had scores in the cognitively impaired range on a brief cognitive screening test, 30% had impaired processing speed, and 11% met cognitive criteria for intellectual disability. Furthermore, 48% of the sample met functional impairment criteria, and poorer cognitive performance was strongly associated with poorer performance-based functional capacity (p<0.001). CONCLUSIONS Cognitive and functional impairments are common among sheltered adults experiencing homelessness, underscoring the need for routine objective cognitive screening and rehabilitation services.

Abstract
The current study examined the feasibility and acceptability of an integrated Cognitive-Behavioral Social Skills Training and Compensatory Cognitive Training (CBSST-CCT) intervention compared with Goal-Focused Supportive Contact (SC) in a pilot randomized controlled trial for people with schizophrenia with high negative symptom severity. The sample included 55 participants from five community settings; masters-level study clinicians delivered interventions on-site. Participants completed assessments of cognitive, functional, and psychiatric symptoms at baseline, mid-treatment, post-treatment (12.5 weeks), and 6-month follow-up. Enrollment goals were not initially met, necessitating the addition of a fifth site; however, all groups and assessments were completed on-site. Study procedures were acceptable, as evidenced by 100% enrollment and completion of baseline assessments following informed consent; however, over 1/3rd of participants dropped out. No modifications were necessary to the intervention procedures and CBSST-CCT fidelity ratings were acceptable. The intervention was deemed acceptable among participants who attended ≥1 session, as evidenced by similar attendance rates in CBSST-CCT compared to SC. Among CBSST-CCT participants, lower positive symptoms were significantly associated with better attendance. Overall, we found mixed evidence for the feasibility and acceptability of the CBSST-CCT protocol in people with schizophrenia with high negative symptoms. Challenges are highlighted and recommendations for future investigations are provided.

Abstract
OBJECTIVE Rapid eye movement sleep behavior disorder (RBD) affects 33-46% of patients with Parkinson's disease (PD) and may be a risk factor for neuropsychological and functional deficits. However, the role of RBD on neuropsychological functioning in PD has yet to be fully determined. We, therefore, examined differences in neurocognitive performance, functional capacity, and psychiatric symptoms among nondemented PD patients with probable RBD (PD/pRBD+) and without (PD/pRBD-), and healthy comparison participants (HC). METHODS Totally, 172 participants (58 PD/pRBD+; 65 PD/pRBD-; 49 HC) completed an RBD sleep questionnaire, psychiatric/clinical questionnaires, performance-based and self-reported functional capacity measures, and underwent a comprehensive neuropsychological battery assessing attention/working memory, language, visuospatial function, verbal and visual learning and memory, and executive function. RESULTS Controlling for psychiatric symptom severity, the PD/pRBD+ group had poorer executive functioning and learning performance than the PD/pRBD- group and poorer neuropsychological functioning across all individual cognitive domains than the HCs. In contrast, PD/pRBD- patients had significantly lower scores than HCs only in the language domain. Moreover, PD/pRBD+ patients demonstrated significantly poorer medication management skills compared to HCs. Both PD groups reported greater depressive and anxiety severity compared to HCs; PD/pRBD+ group also endorsed greater severity of apathy compared to HCs. CONCLUSIONS The presence of pRBD is associated with poorer neuropsychological functioning in PD such that PD patients with pRBD have poorer cognitive, functional, and emotional outcomes compared to HC participants and/or PD patients without pRBD. Our findings underscore the importance of RBD assessment for improved detection and treatment of neuropsychological deficits (e.g., targeted cognitive interventions).

Abstract
Adults who are homeless experience high rates of health conditions and psychological distress, including low IQ and functional status. Resources are available to help these individuals, but provision of support is often contingent upon the identification of a known disability. In this context, we examined case managers' (CMs') subjective estimates of IQ and functional status in 77 adult residents of an urban homeless shelter. Participants completed objective measures of IQ and functional capacity. CMs overestimated IQs of lower IQ (IQ < 90) participants, correctly estimated IQs of average IQ (IQ = 90-110) participants, and underestimated IQs of higher IQ (IQ > 110) participants. CMs correctly identified 2 out of 8 participants meeting criteria for intellectual disability and 4 out of 16 participants with impaired functional status. These findings suggest that subjective evaluations of IQ and functional status are prone to a central tendency bias, leading CMs to overlook clients who are in need of assistance. Consequently, the objective measurement of IQ and functional status in homeless shelters is highly recommended. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Abstract
OBJECTIVE Among people with severe mental illnesses, neuropsychological abilities may contribute to vocational outcomes, such as job attainment, job tenure, and wages earned. The current study aimed to determine the strongest neuropsychological and other modifiable predictors of work outcomes in 153 people with severe mental illness (schizophrenia, 38%; bipolar disorder, 24%; and major depression, 38%) who participated in a 2-year supported employment study. METHODS Assessments of neuropsychological performance, functional capacity, social skills, and psychiatric symptom severity were administered at baseline; work outcomes (job attainment, weeks worked, and wages earned) were collected weekly for 2 years. RESULTS Independent of education, diagnosis, and estimated intellectual functioning, more recent work history and less severe negative symptoms significantly predicted job attainment during the 2-year study. Among the 47% who obtained jobs, better global neuropsychological performance (i.e., lower global deficit score) was a significant predictor of greater weeks worked. Both global neuropsychological performance and more recent work history predicted higher wages earned. CONCLUSIONS Modifiable predictors of supported employment outcomes included cognitive functioning and negative symptom severity; thus, interventions to improve these factors may improve work outcomes and decrease the loss of productivity associated with severe mental illness.

Abstract
Abstract
Objective
Rapid eye movement sleep behavior disorder (RBD) affects 33-46% of patients with Parkinson’s Disease (PD) and may be a risk factor for neuropsychological impairment. However, the cognitive profile in PD patients with RBD has yet to be fully determined. This study examined differences in neuropsychological performance among non-demented PD patients with (PD/RBD+) and without RBD (PD/RBD-), and healthy controls (HC).
Methods
One hundred seventy-five participants, including 45 PD/RBD+ patients, 78 PD/RBD- patients, and 52 HC, completed the RBD sleep questionnaire and underwent a comprehensive neuropsychological battery assessing attention/working memory, language, visuospatial function, verbal and visual learning and memory, and executive function.
Results
The PD/RBD+ group demonstrated significantly poorer global neuropsychological performance compared to both the PD/RBD- and HC groups (p’s < .003; η_p^2 = .16). MANOVA demonstrated significant group differences on all individual cognitive domains (p’s < .001), except visuospatial function (p = .10). Both PD/RBD+ and PD/RBD- patients had significantly lower scores compared to the HCs in the domains of attention/working memory, language, learning, and memory. Additionally, the PD/RBD+ group had significantly lower executive functioning scores compared to the HCs, and poorer learning performance compared to the PD/RBD- group.
Conclusions
Compared to PD patients without RBD, PD/RBD+ patients have greater levels of cognitive impairment specific to the acquisition of new information. Moreover, PD/RBD+ patients have greater executive dysfunction compared to HCs, underscoring the importance of RBD assessment for improved detection and treatment of neuropsychological impairment (e.g., targeted cognitive interventions). Longitudinal investigations are needed to determine the enduring effects of RBD in PD.

Abstract
BACKGROUND Sitting time is associated with adverse physical and mental health outcomes, and premature mortality. Office workers sit for prolonged periods, so are at particular risk. Scientific advances in public health threats are predominantly communicated to the public through media reports. AIMS This study aimed to examine office workers' impromptu responses to media coverage of scientific evidence related to the health risks of sedentary behaviour. METHODS Semi-structured interviews were run with 26 office workers (mean age 35 years), recruited from four organizations in southern England. Within the interview, each participant provided a 'think-aloud' narrative as they read three real-world news reports relating to sedentary behaviour. Thematic analysis was conducted on verbatim transcripts. RESULTS Three themes were extracted from the data: gauging the personal relevance of the news reports; questioning their trustworthiness and challenging the feasibility of proposed sitting-reduction strategies. Participants voiced scepticism about the applicability of the reports to their personal circumstances, and the validity of the reports and the scientific evidence underpinning them. CONCLUSIONS Researchers, press officers and journalists should emphasise the ways in which participants in research studies represent the broader population of office workers, and offer greater transparency in reporting study methods, when reporting scientific advances in sedentary behaviour.

Abstract
Research identifying the effects of cognitive training on negative symptoms of psychosis is limited. We examined the effects of Compensatory Cognitive Training (CCT) on expressive deficits and social amotivation in a randomized controlled trial comparing CCT to standard pharmacotherapy alone in 43 individuals with psychosis. ANCOVA analyses demonstrated significant CCT-associated effects on both expressive deficits and social amotivation. Moreover, improvements in both sub-domains were associated with improvements in global life satisfaction, with improvements in social amotivation also related to increased social contact. CCT appears to be a beneficial treatment approach for improving multiple aspects of negative symptoms.

Abstract
Background: Early psychosocial interventions targeting cognitive and functional outcomes in individuals at clinical high risk for psychosis are a research priority. An even greater need is the identification of effective interventions in underserved populations. Compensatory Cognitive Training (CCT) is a psychosocial intervention with demonstrated efficacy in chronic schizophrenia and first episode psychosis, but remains to be evaluated in pre-illness phases. The aim of this study was to describe the development and implementation of an ongoing pilot randomized controlled trial investigating the efficacy of group-based, manualized CCT, as compared to recreational therapy (RT), for Latino participants at clinical high risk for psychosis (CHR) in both the United States and Mexico. It is hypothesized that, in comparison to those receiving RT, participants receiving CCT will show significant improvements in neurocognitive performance and functional capacity (co-primary outcomes) and self-rated functioning and clinical symptoms (secondary outcomes). Methods: Latino CHR participants aged 12-30 years will be included in the study. Both CCT and RT will be delivered in either Spanish or English, depending on group preference. Additionally, all assessments will be administered in participants' preferred language. A comprehensive assessment of neurocognitive and functional performance and clinical symptomatology will be performed at baseline, mid-intervention (4 weeks, 8 weeks), post-intervention (12 weeks) and 3-month follow-up. The primary outcome measures are neurocognition and functional capacity, as assessed by the MATRICS (Measurement and Treatment Research in Cognition in Schizophrenia) Consensus Cognitive Battery and the University of California, San Diego Performance-Based Skills Assessment-Brief, respectively. Furthermore, secondary outcomes measures will be used to examine change in clinical symptoms and self-reported functioning in response to CCT versus RT. Discussion: The evaluation of a novel treatment such as CCT in CHR youth will provide empirical support for a low risk, comprehensive cognitive intervention that could have important implications for public health if it improves neurocognition and functioning.

Abstract
Background and Aims: Legalization of cannabis (CB) for both medicinal and, in some states, recreational use, has given rise to increasing usage rates across the country. Of particular concern are indications that frequent CB use may be selectively harmful to the developing adolescent brain compared with adult-onset usage. However, the long-term effects of heavy, adolescent CB use on brain structure and cognitive performance in late-life remain unknown. A critical brain region is the hippocampus (HC), where there is a striking intersection between high concentrations of cannabinoid 1 (CB1) receptors and age-related pathology. Design: We investigated whether older adults (average age=66.6+7.2 years old) with a history of early life CB use show morphological differences in hippocampal subregions compared with older, nonusers. Methods: We performed high-resolution magnetic resonance imaging combined with computational techniques to assess cortical thickness of the medial temporal lobe, neuropsychological testing, and extensive drug use histories on 50 subjects (24 formerly heavy cannabis users [CB+ group] abstinent for an average of 28.7 years, 26 nonusers [CB− group]). We investigated group differences in hippocampal subregions, controlling for age, sex, and intelligence (as measured by the Wechsler Test of Adult Reading), years of education, and cigarette use. Results: The CB+ subjects exhibited thinner cortices in subfields cornu ammonis 1 [CA1; F(1,42)=9.96, p=0.0003], and CA2, 3, and the dentate gyrus [CA23DG; F(1,42)=23.17, p<0.0001], and in the entire HC averaged over all subregions [F(1,42)=8.49, p=0.006]. Conclusions: Negative effects of chronic adolescent CB use on hippocampal structure are maintained well into late life. Because hippocampal cortical loss underlies and exacerbates age-related cognitive decline, these findings have profound implications for aging adults with a history of early life usage. Clinical Trial Registration: ClinicalTrials.gov # NCT01874886.

Abstract
BACKGROUND The translocase of outer mitochondrial membrane 40 (TOMM40), which lies in linkage disequilibrium with the apolipoprotein E (APOE) gene, has been implicated in Alzheimer's disease (AD). TOMM40 influences AD pathology through mitochondrial neurotoxicity, and the medial temporal lobe (MTL) is the most likely brain region for identifying early manifestations of AD-related morphology changes. While early reports indicated that the longer length poly-T allele of TOMM40 increases risk for AD, these findings have not been consistently replicated in further studies. We examined the effect of TOMM40 and APOE on regional brain positron emission tomography (PET) 2-(1-{6-[(2 [F18]fluoroethyl) (methyl) amino]-2-naphthyl}ethylidene)malononitrile (FDDNP) binding values in MTL. METHODS A total of 73 non-demented older adults (42 females; mean age: 62.9(10.9) completed genotyping for both APOE and TOMM40 and received FDDNP-PET scans. For TOMM40, the lengths of the poly-T sequence were classified as short (14-20 repeats; S), long (21-29 repeats, L) or very long (>29 repeats, VL). Using general linear models, we examined medial temporal lobe FDDNP binding and cognitive functioning between TOMM40 and APOE-4 groups, with age, sex, and education as covariates. RESULTS Data from 30 individuals with APOE-4 and L TOMM40 poly-T length, 11 non E4 TOMM40 S/S, 14 non E4 TOMM40 S/VL and 13 non E4 TOMM40 VL/VL were analyzed. Medial temporal FDDNP binding differed significantly between TOMM40/APOE groups (F(3,62) = 3.3,p = .03). Participants with TOMM40 S/S exhibited significantly lower binding compared to TOMM40 S/VL and APOE-4 carriers. We did not find a significant relationship between TOMM40 poly-T lengths/APOE risk groups and cognitive functioning. CONCLUSIONS This is the first report to demonstrate a significant association between longer TOMM40 poly-T lengths and higher medial temporal plaque and tangle burden in non-demented older adults. Identifying biomarkers that are risk factors for AD will enhance our ability to identify subjects likely to benefit from novel AD treatments.

Abstract
OBJECTIVES People living with HIV (PLWH) are more likely to report sleep difficulties and cognitive deficits. While cognitive impairment associated with sleep problems have been found in healthy and medical populations, less is known about the effects of poor sleep health (SH) on cognition among PLWH. This study examined differences in cognitive performance among participants classified based upon their HIV status and reported SH. METHODS One hundred sixteen (N=116) adults recruited from the Greater Los Angeles community were administered a comprehensive cognitive test battery and completed a questionnaire about SH. Participants were classified into the following HIV/SH groups: [HIV+/good sleep health (SH+; n=34); HIV-/SH+ (n=32); HIV-/poor sleep health (SH-; n=18) and HIV+/SH- (n=32)]. RESULTS For both HIV+ and HIV- individuals, poor SH was associated with lower cognitive performance, with the domains of learning and memory driving the overall relationship. The HIV+/SH- group had poorer scores in domains of learning and memory compared to the SH+ groups. Additionally, the HIV-/SH- group demonstrated poorer learning compared to the HIV-/SH+ group. CONCLUSIONS Our findings suggest that sleep problems within medical populations are relevant to cognitive functioning, highlighting the clinical and scientific importance of monitoring sleep health and cognition to help identify individuals at greatest risk of poor health outcomes. Longitudinal investigations using both objective and subjective measures of sleep are needed to determine the robustness of the current findings and the enduring effects of poor SH in the context of chronic disease.

Abstract
BACKGROUND In Los Angeles County, the rates of sexually transmitted infections and diseases among African Americans represent a significant public health disparity. Older African American women are at particular risk as they are more likely to engage in high-risk sexual behaviors and report social isolation and loneliness than their younger counterparts. However, the literature on the relationship between sexual health and mental health in this group is limited. The purpose of this study was to use a community-based participatory research (CBPR) approach to better understand sexual health behaviors and mental health among African American women over 50 years of age who reside in South Los Angeles. MATERIALS AND METHODS This project was divided into two phases. Phase I (January-March 2017) of the project consisted of four dialog/focus groups (N = 45) (ages: 50-80; Mage = 67). The purpose of Phase II (April 2017) was to present study results from Phase I to the community via a community-based conference, as well as gather feedback and generate discussion about the next steps for community prevention/intervention. RESULTS Women reported that they did not feel comfortable discussing sexual practices with their physician, partners, and friends. Most women identified depression, loneliness, and self-esteem issues as reasons for engaging in high-risk sexual behaviors. During Phase II, potential intervention avenues emerged to address issues such as lack of physician-patient communication, lack of community support, and dialogs about sex. CONCLUSIONS The use of CBPR greatly enhanced our knowledge of the core issues surrounding sexual health and mental health among older African American women.

Abstract
Neuropsychological abilities may underlie successful performance of everyday functioning and social skills. We aimed to determine the strongest neuropsychological predictors of performance-based functional capacity and social skills performance across the spectrum of severe mental illness (SMI). Unemployed outpatients with SMI (schizophrenia, bipolar disorder, or major depression; n = 151) were administered neuropsychological (expanded MATRICS Consensus Cognitive Battery), functional capacity (UCSD Performance-Based Skills Assessment-Brief; UPSA-B), and social skills (Social Skills Performance Assessment; SSPA) assessments. Bivariate correlations between neuropsychological performance and UPSA-B and SSPA total scores showed that most neuropsychological tests were significantly associated with each performance-based measure. Forward entry stepwise regression analyses were conducted entering education, diagnosis, symptom severity, and neuropsychological performance as predictors of functional capacity and social skills. Diagnosis, working memory, sustained attention, and category and letter fluency emerged as significant predictors of functional capacity, in a model that explained 43% of the variance. Negative symptoms, sustained attention, and letter fluency were significant predictors of social skill performance, in a model explaining 35% of the variance. Functional capacity is positively associated with neuropsychological functioning, but diagnosis remains strongly influential, with mood disorder participants outperforming those with psychosis. Social skill performance appears to be positively associated with sustained attention and verbal fluency regardless of diagnosis; however, negative symptom severity strongly predicts social skills performance. Improving neuropsychological functioning may improve psychosocial functioning in people with SMI.

Abstract
Tuberculosis (TB) is one of the major public health problem among contagious diseases in Pakistan. TB diagnosis mainly depends on sputum smear microscopy. The main objective of this study was to evaluate the effects of household bleach on sputum smear microscopy to concentrate acid fast bacilli for the diagnosis of pulmonary tuberculosis. Sputum specimens of 200 suspected TB patients were collected for the study. Smears were prepared from the purulent part of sputum sample before and after bleach treatment, heat fixed and stained with the ZN technique. The obtained data were analyzed by chi-squared test using SPSS software. Out of 200 isolates, 22 (11%) patients had positive smears for acid fast bacilli (AFB) by direct ZN staining. After treatment with household bleach (NaOCL) and centrifugation, the number of AFB positive patients were increased from 22 (11%) to 37 (18.5%). The bleach-concentration method for sputum samples significantly increased the TB detection rate as compared to direct sputum smear microscopy. Thus, a shift from direct sputum microscopy to bleach-concentration technique should be considered a better method for detection of AFB in sputum through smear microscopy.

Abstract
The purpose of the current study was to examine the independent and interactive effects of social adversity (SA) and HIV infection on subcortical shape alterations and cognitive functions. Participants included HIV+ (n = 70) and HIV- (n = 23) individuals who underwent MRI, neurocognitive and clinical assessment, in addition to completing questionnaires from which responses were used to create an SA score. Bilateral amygdalae and hippocampi were extracted from T1-weighted images. Parametric statistical analyses were used to compare the radial distance of the structure surface to a median curve to determine the presence of localized shape differences as a function of HIV, SA and their interaction. Next, multiple regression was used to examine the interactive association between HIV and SA with cognitive performance data. An HIV*SA interactive effect was found on the shape of the right amygdala and left hippocampus. Specifically, HIV-infected participants (but not HIV-uninfected controls) who evidenced higher levels of SA displayed an inward deformation of the surface consistent with reduced volume of these structures. We found interactive effects of HIV and SA on learning/memory performance. These results suggest that HIV+ individuals may be more vulnerable to neurological and cognitive changes in the hippocampus and amygdala as a function of SA than HIV- individuals, and that SA indicators of childhood SES and perceived racial discrimination are important components of adversity that are associated with cognitive performance.

Abstract
OBJECTIVES Recent studies suggest that intraindividual variability (IIV) of neuropsychological performance may be sensitive to HIV-associated neurologic compromise. IIV may be particularly dependent upon the integrity of frontal-subcortical systems, and therefore may be a meaningful phenotype in HIV. We examined the relationship between change in IIV and white matter integrity among HIV seropositive (HIV+) and HIV seronegative (HIV-) individuals. METHOD The sample consisted of 38 HIV+ participants and 26 HIV- control participants who underwent neuroimaging and a neuropsychological evaluation at baseline and at 2-year follow-up evaluation. RESULTS Among HIV+ participants, increases in IIV (greater dispersion) were related to lower fractional anisotropy (FA) values in the anterior thalamic radiations (ATR) and the superior longitudinal fasciculus (SLF). Changes in mean-level global cognitive functioning were not significantly related to white matter integrity. Additionally, there was a significant Group × IIV interaction effect in the SLF demonstrating that the relationship between IIV and white matter integrity was specific to HIV. CONCLUSIONS Overall, findings suggest that IIV may be more sensitive, relative to mean-level global cognitive functioning, in the detection of neurologic compromise among HIV+ individuals.

Abstract
INTRODUCTION The translocase of outer mitochondrial membrane 40 (TOMM40), which lies in linkage disequilibrium with apolipoprotein E (APOE), has received attention more recently as a promising gene in Alzheimer's disease (AD) risk. TOMM40 influences AD pathology through mitochondrial neurotoxicity, and the medial temporal lobe (MTL) is the most likely brain region for identifying early manifestations of AD-related morphology changes. METHODS In this study, we examined the effects of TOMM40 using high-resolution magnetic resonance imaging in 65 healthy, older subjects with and without the APOE ε4 AD-risk variant. RESULTS Examining individual subregions within the MTL, we found a significant relationship between increasing poly-T lengths of the TOMM40 variant and thickness of the entorhinal cortex only in subjects who did not carry the APOE ε4 allele. DISCUSSION Our data provide support for TOMM40 variant repeat length as an important contributor to AD-like MTL pathology in the absence of APOE ε4.

Abstract
OBJECTIVE Historically marginalized groups are likely to be exposed to social adversity, which predicts important mental health outcomes (e.g., depression). Despite the well-established relationship between adversity and poor health, few studies have examined how adversity differentially predicts mental health among people living with multiple, co-occurring marginalized identities or statuses. The current study fills this gap by examining whether relationships between social adversity and depressive symptoms differed between those living with or without a stigmatized disease (i.e., HIV) and/or marginalized racial/ethnic identity (i.e., African American). METHOD A community sample of men and women (N = 149) completed questionnaires assessing demographics and depressive symptoms. Additionally, a composite index of social adversity was derived from measures of perceived discrimination, socioeconomic status, financial restriction to receiving medical care, and perceived neighborhood characteristics. Multiple regression was used to test whether relationships between adversity and depressive symptoms differed as a function of HIV status and racial/ethnic identity. RESULTS A significant 3-way interaction between social adversity, HIV status, and racial/ethnic identity indicated that there was a direct relationship between adversity and depressive symptoms for HIV-positive (HIV+) African Americans but not for HIV-negative (HIV-) African Americans, HIV+ Caucasians, or HIV- Caucasians. Further, HIV+ African Americans evidenced a significantly greater relationship between adversity and depressive symptoms compared with HIV- African Americans, but not compared with other groups. CONCLUSIONS The findings suggest that HIV+ African Americans may be at risk for higher depressive symptoms amid adversity, highlighting the importance of evaluating intersectional identities/statuses in the context of mental health.

Abstract
BACKGROUND The current study examined the independent and interactive effects of HIV and marijuana (MJ) use on brain structure and cognitive function among a sample of HIV-positive (HIV+) and HIV-negative (HIV-) individuals. METHODS Participants (HIV+, n=48; HIV-, n=29) individuals underwent cognitive testing, questionnaires about substance use, and brain MRI. The HIV+ group was clinically stable based upon current plasma CD4 count, 50% had undetectable viral load (i.e.,<20 copies/mL), and all were on a stable regimen of cART. RESULTS For HIV+ and HIV- participants, higher levels of MJ use were associated with smaller volumes in the entorhinal cortex and fusiform gyrus. HIV status (but not MJ use) was associated with cingulate thickness, such that HIV+ participants evidenced smaller thickness of the cingulate, as compared to HIV- controls. Regarding neurocognitive functioning, there was a HIV*MJ interactive effect on global cognition, such that when the amount of MJ use was less than 1.43g per week, the HIV- group displayed significantly better neurocognitive performance than the HIV+ group (t=3.14, p=0.002). However, when MJ use reached 1.43g per week, there were no significant HIV group differences in global cognitive performance (t=1.39, p=0.168). CONCLUSIONS Our results show independent and interactive effects of HIV and MJ on brain structure and cognition. However, our results do not support that HIV+ MJ users are at greater risk for adverse brain or cognitive outcomes compared to HIV- MJ users.

Abstract
The current study examined the independent and combined effects of HIV and marijuana (MJ) use (no use, light use, and moderate-to-heavy use) on neurocognitive functioning among a convenience sample of HIV-positive (HIV+) and HIV-negative (HIV-) individuals recruited from HIV community care clinics and advertisements in the Greater Los Angeles area. MJ users consisted of individuals who reported regular use of MJ for at least 12 months, with last reported use within the past month. Participants included 89 HIV+ (n = 55) and HIV- (n = 34) individuals who were grouped into non-users, light users, and moderate-to-heavy users based on self-reported MJ use. Participants were administered a brief cognitive test battery and underwent laboratory testing for CD4 count and viral load. HIV+ individuals demonstrated lower performance on neurocognitive testing than controls, and moderate-to-heavy MJ users performed more poorly on neurocognitive testing than light users or non-users. Moderate-to-heavy HIV+ users performed significantly lower on learning/memory than HIV- moderate-to-heavy users (MD = -8.34; 95% CI: -16.11 to -0.56) as well as all other comparison groups. In the domain of verbal fluency, HIV+ light users outperformed HIV- light users (MD = 7.28; 95% CI: 1.62-12.39), but no HIV group differences were observed at other MJ use levels. HIV+ MJ users demonstrated lower viral load (MD = -0.58; 95% CI: -1.30 to 0.14) and higher CD4 count than non-users (MD = 137.67; 95% CI: 9.48-265.85). The current study findings extend the literature by demonstrating the complex relationship between HIV status and MJ use on neurocognitive and clinical outcomes.

Abstract
Gastro-oesophageal reflux disease (GORD) is a common disorder which significantly impairs the quality of life. Recently an EndoCinch system has been described, with an approach to the treatment of GORD that would obviate the need for long-term proton pump inhibitors and the cost and potential risk of laparoscopic Nissen fundoplication. We set outto evaluate the status of this new technique for the management of GORD. We review the literatures (publications and abstracts) regarding safety, efficacy, and durability of this new antireflux procedure. On the whole, this new antireflux technique produced significant improvement in GORD symptomatology and quality of life and reduced the use of antireflux medication. However, it failed to normalize acid reflux, long-term durability data are lacking, and some serious side effects have been reported. In conclusion, EndoCinch has the potential to treat patients with this common ailment. However, further studies are necessary to determine what modifications to this antireflux technique are required in order to produce the maximum clinical benefit.

Abstract
Separately collected urine ("yellow water") can be utilized as fertilizer. In order to decrease storage volumes and energy consumption for yellow water transport to fields, enrichment of nutrients in yellow water has to be considered. Laboratory-scale batch freeze concentration of yellow water has been tested in ice-front freezing apparatus: a stirred vessel and a falling film freeze concentrator (coolant temperatures: -6 to -16 degrees C). With progressing enrichment of the liquid concentrate, the frozen ice was increasingly contaminated with yellow water constituents (ammonia, total nitrogen, total phosphorus, TOC, and salts determined as conductivity). The higher the initial salinity of the yellow water and the lower the mechanical agitation of the liquid phase contacting the growing ice front, the more the frozen ice was contaminated. The results indicate, that in ice-front freezing devices multistage processes are necessary, i.e. the melted ice phase has to be purified (and the concentrates must be further enriched) in a second or even in a third stage. Energy consumption of this process is very high. However, technical scale suspension freeze concentration is reasonable in centralized ecological sanitation schemes if the population exceeds 0.5 million and distance of yellow water transportation to fields is more than 80 km.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GORD) is, in the main, treated with either proton pump inhibitor (PPI) drugs or a Nissen fundoplication operation. Recently, BARD developed Endocinch, a device used to place sutures just below the oesophagogastric junction (OGJ) to treat GORD. AIM To evaluate the long term benefit of the Endocinch technique in patients seen up to 12 months post procedure. PATIENTS Twenty six patients with symptoms of GORD were recruited and had the procedure performed. Four patients were lost to follow up. METHODS Twenty two patients completed their one year follow up. Pre procedure and post procedure (up to 12 months) assessments included symptom scoring (DeMeester), upper intestinal endoscopy, oesophageal manometry and 24 hour oesophageal pH, and completion of quality of life (QOL) questionnaires. RESULTS Mean age was 39 years (range 22-62). Heartburn symptom score was reduced from a mean value of 19.22 at baseline to 7.5 at 12 months (n=22) (p<0.0001). Regurgitation score reduced from a mean of 2.27 at baseline to 0.86 at 12 months (n=22) (p<0.001). Mean (SEM) pH DeMeester acid score was reduced from 44.1 (4.3) to 33.32 (4.73) (p=0.028) at three month post procedure. Percentage upright acid exposure and number of reflux episodes were also reduced significantly. Use of PPIs was reduced by 64% at 12 months post procedure. All QOL assessments showed significant improvement (p=0.01). All transient post procedure complaints resolved within 72 hours. CONCLUSION The Endocinch procedure is an effective and safe outpatient procedure that offers GORD patients significant improvement in symptomatology, QOL, and reduced requirements for PPIs over at least a one year period.

Abstract
OBJECTIVE To study the validity and feasibility of a computerized version of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. METHODS Thirty patients with osteoarthritis (OA) of the knee completed both a paper and a computerized version of WOMAC in random order. The visual analog scaled version of WOMAC, VA3.0, was used. We studied criterion validity by comparing the paper and computerized versions. RESULTS All patients completed the computerized version without undue difficulty. Criterion validity, based on aggregated subscale scores, was excellent: Pain, ICC = 0.89, Stiffness, ICC = 0.87, Physical Function, ICC = 0.95. CONCLUSION The computerized version of WOMAC VA3.0 is a valid alternative to the paper version.
