"Phylogenomic insights into brucellaceae: The Pseudochrobactrum algeriensis case".

The genus Pseudochrobactrum encompasses free-living bacteria phylogenetically close to Ochrobactrum opportunistic pathogens and to Brucella, facultative intracellular parasites causing brucellosis, a worldwide-extended and grave zoonosis. Recently, Pseudochrobactrum strains were isolated from Brucella natural hosts on Brucella selective media, potentially causing diagnostic confusions. Strikingly, P. algeriensis was isolated from cattle lymph nodes, organs that are inimical to bacteria. Here, we analyse P. algeriensis potential virulence factors in comparison with Ochrobactrum and Brucella. Consistent with genomic analyses, Western-Blot analyses confirmed that P. algeriensis lacks the ability to synthesize the N-formylperosamine O-polysaccharide characteristic of the lipopolysaccharide (LPS) of smooth Brucella core species. However, unlike other Pseudochrobactrum but similar to some early diverging brucellae, P. algeriensis carries genes potentially synthetizing a rhamnose-based O-polysaccharide LPS. Lipid A analysis by MALDI-TOF demonstrated that P. algeriensis LPS bears a lipid A with a reduced pathogen-associated molecular pattern, a trait shared with Ochrobactrum and Brucella that is essential to generate a highly stable outer membrane and to delay immune activation. Also, although not able to multiply intracellularly in macrophages, the analysis of P. algeriensis cell lipid envelope revealed the presence of large amounts of cationic aminolipids, which may account for the extremely high resistance of P. algeriensis to bactericidal peptides and could favor colonization of mucosae and transient survival in Brucella hosts. However, two traits critical in Brucella pathogenicity are either significantly different (T4SS [VirB]) or absent (erythritol catabolic pathway) in P. algeriensis. This work shows that, while diverging in other characteristics, lipidic envelope features relevant in Brucella pathogenicity are conserved in Brucellaceae. The constant presence of these features strongly suggests that reinforcement of the envelope integrity as an adaptive advantage in soil was maintained in Brucella because of the similarity of some environmental challenges, such as the action of cationic peptide antibiotics and host defense peptides. This information adds knowledge about the evolution of Brucellaceae, and also underlines the taxonomical differences of the three genera compared.

Risk factors for PTSD symptoms following PICU admission for childhood septic shock.

ObjectivePaediatric intensive care unit (PICU) admission represents a traumatic event for many children. Follow-up studies have found post-traumatic stress disorder (PTSD) rates of 10-30%, with a particular prevalence following admission for sepsis. Dysregulated inflammatory responses are associated with PTSD. Sepsis involves a marked inflammatory response but the relationship between this and PTSD have not been clearly established. In this study we investigate associations between the inflammatory response, psychosocial risk factors, and PTS symptoms following PICU admission for septic shock.We investigate the outcomes for children aged > 3 years, discharged from one PICU following admission for septic shock between 2010 and 2017. The study was a retrospective analysis of PICU-specific PTS symptoms reported by parents at any time since discharge via the Trauma and Behavior Health screen. Demographics, pre-morbid health characteristics, and exposure to other traumatic events were assessed. Clinical characteristics and blood test results at admission and at 48 h were recorded from clinical records. Multiple linear regression was used to investigate relationships between PTS symptom scores and predictor variables.Data for 65 participants (48% male, median assessment age 8.0 years) was available. Median time since admission was 5.1 years. 30.8% children scored at risk of PTSD at any time since discharge Symptoms were significantly associated with acute CRP rise (p 0.03), other trauma exposures (p = 0.01), and female gender (p =0.04).PTS symptoms in children who have survived septic shock are prevalent. These findings support a possible contribution of acute inflammatory changes, cumulative traumatic exposure, and female gender in post-PICU PTSD development.

Staphylococcal aureus outbreaks in neonatal intensive care units: strategies, nuances, and lessons learned from the frontline.

Methicillin-resistant Staphylococcus aureus (MRSA) infections in neonates can result in significant morbidity and mortality. However, comparatively to adults, neonatal MRSA data remains relatively scarce. Additionally, while evidence-driven practices for adults have seen considerable progress, neonatal infection prevention strategies remain poorly described. The Leeds Newborn Service adopted a series of infection prevention and control (IPC) measures following a rise in MRSA cases in 2008-2009. This narrative review presents IPC measures for neonatal MRSA and methicillin-sensitive Staphylococcus aureus (MSSA) infections and reflects upon local challenges and successes of these interventions. Our experience underscores the importance of an adaptive, evidence-based strategy, tailored to the neonatal population. Effectively addressing MRSA/MSSA requires continuous monitoring with sustained targeted interventions. Our key learning points highlight the intertwined difficulties of specific neonatal requirements and lack of definitive IPC guidance, suggesting a holistic approach is key for successful IPC outcomes in the neonatal intensive care unit setting.

Out-of-hours versus in-hours delivery of antenatally diagnosed transposition of the great arteries: outcomes from a United Kingdom Tertiary Centre.

OBJECTIVE: To study the impact of out-of-hours delivery on outcome for neonates with antenatally diagnosed transposition of the great arteries. SETTING: Tertiary paediatric cardiology centre (Yorkshire, United Kingdom), with co-located tertiary neonatal unit. PATIENTS: Neonates with antenatally diagnosed simple transposition of the great arteries delivered out-of-hours (Monday to Friday 17:00-08:00 and weekends) versus in-hours between 2015 and 2020. OUTCOME: The primary outcome was survival to hospital discharge. Secondary outcomes included neurological morbidity, length of stay, and time to balloon atrial septostomy. RESULTS: Of 51 neonates, 38 (75%) were delivered out-of-hours. All neonates born in the tertiary centre survived to discharge. Time to balloon atrial septostomy was slightly longer for out-of-hours deliveries compared to in-hours (median 130 versus 93 mins, p = 0.33). Neurological morbidity occurred for nine (24%) patients in the out-of-hours group and one (8%) in-hours (OR 3.72, 95% CI: 0.42-32.71, p = 0.24). Length of stay was also similar (18.5 versus 17.3 days, p = 0.59). Antenatal diagnosis of a restrictive atrial septum was associated with a lower initial pH (7.03 versus 7.13; CI: 0.03-0.17, p = 0.01), longer length of stay (22.6 versus 17.3 days; CI: 0.37-10.17, p = 0.04), and increased neurological morbidity (44% versus 14%; OR 4.80, CI 1.00-23.15, p = 0.05). A further three neonates were delivered in surrounding hospitals, with a mortality of 67% (versus 0 in tertiary centre; OR 172, CI 5-5371, p = 0.003). CONCLUSION: Neonates with antenatally diagnosed transposition of the great arteries have similar outcomes when delivered out-of-hours versus in-hours. Antenatal diagnosis of restrictive atrial septum is a significant predictor of worse outcomes. In our region, delivery outside the tertiary cardiac centre had a significantly higher risk of mortality.

In vivo single-cell transcriptomics reveal Klebsiella pneumoniae skews lung macrophages to promote infection.

The strategies deployed by antibiotic-resistant bacteria to counteract host defences are poorly understood. Here, we elucidate a novel host-pathogen interaction resulting in skewing lung macrophage polarisation by the human pathogen Klebsiella pneumoniae. We identify interstitial macrophages (IMs) as the main population of lung macrophages associated with Klebsiella. Single-cell transcriptomics and trajectory analysis of cells reveal type I IFN and IL10 signalling, and macrophage polarisation are characteristic of infected IMs, whereas Toll-like receptor (TLR) and Nod-like receptor signalling are features of infected alveolar macrophages. Klebsiella-induced macrophage polarisation is a singular M2-type we termed M(Kp). To rewire macrophages, Klebsiella hijacks a TLR-type I IFN-IL10-STAT6 axis. Absence of STAT6 limits Klebsiella intracellular survival and facilitates the clearance of the pathogen in vivo. Glycolysis characterises M(Kp) metabolism, and inhibition of glycolysis results in clearance of intracellular Klebsiella. Capsule polysaccharide governs M(Kp). Klebsiella also skews human macrophage polarisation towards M(Kp) in a type I IFN-IL10-STAT6-dependent manner. Klebsiella induction of M(Kp) represents a novel strategy to overcome host restriction, and identifies STAT6 as target to boost defences against Klebsiella.

Neuropsychological abilities underpinning academic attainment in children born extremely preterm.

Children born extremely preterm (EP) have poorer academic attainment than their term-born peers. There is a need to identify the specific cognitive mechanisms that are associated with poor academic attainment in preterm populations to inform the development of intervention strategies. A parallel mediation analysis was conducted with cross-sectional data from 152 EP children (< 27 weeks of gestation) and 120 term-born controls who were assessed at age 11. Mathematics and reading attainment was assessed using the Wechsler Individual Achievement Test 2nd Edition. Controlling for sex and socio-economic status we evaluated the following mediators: verbal working memory, visuospatial working memory, verbal processing speed, attention, and visuospatial processing. These were assessed using subtests from the standardized NEPSY-II test and Wechsler Intelligence Scale for Children-5th Edition. Verbal working memory, visuospatial working memory, visuospatial processing and verbal processing speed, but not attention, were significant independent mediators between EP birth and attainment in reading. No direct relationship between EP birth and reading attainment remained in the mediated model. All five neuropsychological variables mediated the relationship between EP birth and attainment in mathematics, but a direct effect of EP birth on mathematics remained in the mediated model. Together, all five neuropsychological abilities indirectly explained 44% of the variance in reading and 52% of the variance in mathematics. Visuospatial processing was the strongest mediator of both mathematics and reading. Components of executive function, especially visuospatial processing, are important predictors of academic attainment. Interventions to improve visuospatial skills could be trialed in EP populations.

Growth in extremely preterm children born in England in 1995 and 2006: the EPICure studies.

OBJECTIVES: To determine growth outcomes at 11 years of age in children born <27 weeks of gestation in England in 2006 (EPICure2) and to compare growth from birth to 11 years of age for births<26 weeks with those in England in 1995 (EPICure). METHODS: 200 EPICure2 children assessed at 11 years alongside 143 term-born controls. Growth measures from birth to 11 years were compared for births<26 weeks between EPICure2 (n=112) and EPICure (n=176). Growth parameter z-scores were derived from 1990 UK standards. RESULTS: Among EPICure2 children, mean z-scores for height and weight were close to the population standards (0.08 and 0.18 SD, respectively) but significantly below those of controls: difference in mean (Δ) z-scores for weight -0.42 SD (95% CI -0.68 to -0.17), for height -0.45 SD (-0.70 to -0.20) and for head circumference (HC) -1.05 SD (-1.35 to -0.75); mean body mass index (BMI) z-score in EPICure2 children was 0.18 SD, not significantly different from controls (0.43 SD, p=0.065). Compared with EPICure, EPICure2 children born <26 weeks at 11 years had higher z-scores for weight (Δ 0.72 (0.47, 0.96)), height (Δ 0.55 (0.29, 0.81)) and BMI (Δ 0.56 (0.24, 0.87)), which were not fully explained by perinatal/demographic differences between eras. Weight catch-up was greater from term-age to 2.5/3 years in EPICure2 than in EPICure (1.25 SD vs 0.53 SD; p<0.001). Poor HC growth was observed in EPICure2, unchanged from EPICure. CONCLUSIONS: Since 1995, childhood growth in weight, height and BMI have improved for births <26 weeks of gestation, but there was no improvement in head growth.

Disturbed sleep in children born extremely preterm is associated with behavioural and emotional symptoms.

AIM: To determine whether children born extremely preterm are at increased risk for sleep disturbances and to explore relationships between extremely preterm birth, sleep and attention-deficit/hyperactivity disorder (ADHD) symptoms and emotional symptoms. METHOD: EPICure2 cohort study. Parents of 165 children born ≤26 weeks' gestation (53% male) and 121 children born at term (43% male) completed the Children's Sleep Habits Questionnaire, sleep disordered breathing subscale of the Pediatric Sleep Questionnaire, the emotional problems scale of the Strengths and Difficulties Questionnaire and the ADHD Rating Scale-5 at 11 years of age. RESULTS: Extremely preterm children had greater habitual snoring (adjusted odds ratio 6.8; 95% confidence interval 2.3, 20.3), less frequently fell asleep within 20 minutes (Cohen's d 0.33), higher night wakings (d 0.44) and daytime sleepiness scores (d 0.40) than term-born children; there was no between-group difference in sleep duration scores. Among children without severe disability, night wakings scores partially mediated the relationship between preterm birth and inattention (additional 5% of variance explained), hyperactivity/impulsivity (13%) and emotional problems (9%). Snoring partially mediated the relationship between preterm birth, hyperactivity/impulsivity and inattention (additional 1-5% of variance). CONCLUSION: Children born extremely preterm are at increased risk of disturbed sleep compared to term-born children. As night wakings partially mediated the relationship between preterm birth and ADHD symptoms and emotional problems, reducing sleep disturbance may improve sleep and reduce attention and emotional problems in this population.

No change in neurodevelopment at 11 years after extremely preterm birth.

OBJECTIVE: To determine whether improvements in school age outcomes had occurred between two cohorts of births at 22-25 weeks of gestation to women residents in England in 1995 and 2006. DESIGN: Longitudinal national cohort studies. SETTING: School-based or home-based assessments at 11 years of age. PARTICIPANTS: EPICure2 cohort of births at 22-26 weeks of gestation in England during 2006: a sample of 200 of 1031 survivors were evaluated; outcomes for 112 children born at 22-25 weeks of gestation were compared with those of 176 born in England during 1995 from the EPICure cohort. Classroom controls for each group acted as a reference population. MAIN OUTCOME MEASURES: Standardised measures of cognition and academic attainment were combined with parent report of other impairments to estimate overall neurodevelopmental status. RESULTS: At 11 years in EPICure2, 18% had severe and 20% moderate impairments. Comparing births at 22-25 weeks in EPICure2 (n=112), 26% had severe and 21% moderate impairment compared with 18% and 32%, respectively, in EPICure. After adjustment, the OR of moderate or severe neurodevelopmental impairment in 2006 compared with 1995 was 0.76 (95% CI 0.45 to 1.31, p=0.32). IQ scores were similar in 1995 (mean 82.7, SD 18.4) and 2006 (81.4, SD 19.2), adjusted difference in mean z-scores 0.2 SD (95% CI -0.2 to 0.6), as were attainment test scores. The use of multiple imputation did not alter these findings. CONCLUSION: Improvements in care and survival between 1995 and 2006 are not paralleled by improved cognitive or educational outcomes or a reduced rate of neurodevelopmental impairment.

Electronic food records among middle-aged and older people: A comparison of self-reported and dietitian-assisted information.

AIM: Nutrition-based applications ("apps") offer enormous research potential, however evidence of their use and acceptability among older adults is limited. We compared self-reported and dietitian-adjusted dietary intake records among adults aged 55 to 75 years using the Research Food Diary (RFD) app. METHODS: Participants were recruited from the 45 and Up Study and completed a 3-day food record using the RFD. A follow-up dietetic telephone interview was performed to confirm the electronic dietary data. Independent of these interviews, a set of adjustments based on dietetic skills, nutritional database knowledge, food composition and dietary assessment was established to resolve probable reporting errors. The "adjusted" and "dietitian-assisted" records were compared to self-reported records for nutrient intakes and serves of The Five Food Groups using one-way repeated measures analysis of variance. RESULTS: Sixty-two participants were recruited, with 48 using the RFD app which included eight records without any identified errors. Reporting errors contained in the raw self-reported records included: food items with missing/implausible quantities or insufficient descriptions to allow automatic coding. After removal of unusable records, 44 records were analysed. Differences were found between the self-reported and adjusted records for protein, calcium, vitamin B12 , zinc and dairy food serves (all P < .001; differences up to 8%). No significant differences were found between the adjusted and dietitian-assisted measures. CONCLUSIONS: Similarities between adjusted and dietitian-assisted records suggest carefully applied dietetic assumptions are likely to improve accuracy of self-reported intake data where dietitian interviews are not possible. We provide four key recommendations to guide this process.

Neuropsychiatric profile of paediatric hypothalamic hamartoma: systematic review and case series.

AIM: To evaluate neuropsychiatric comorbidities in children and adolescents with hypothalamic hamartoma. METHOD: We retrospectively analysed case notes for all individuals with hypothalamic hamartoma referred to Great Ormond Street Hospital, London, between 2000 and 2016. In addition, a systematic review aiming to identify all previous paediatric case series was performed. Psychiatric symptoms, demographics, physical comorbidities, and cognitive functioning were recorded for all cases where possible. Analyses were performed to determine which factors were associated with psychopathology and potential mechanisms investigated. RESULTS: Forty-six cases were included in the case series (28 males, 18 females; mean age at assessment 11y 8mo [1y 11mo-16y 11mo, SD 4y 0mo]). Twenty-nine papers representing data from 264 cases met inclusion criteria for the systematic review. Overall, at least 50% of cases presented with psychopathology. Epilepsy, intellectual disability, and male sex were associated with externalizing disorders (attention-deficit/hyperactivity disorder, conduct and oppositional defiance disorders, and rage attacks). Intellectual disability mediated the effects of epilepsy on externalizing psychopathology. No factors were associated with internalizing disorders (anxiety and depressive disorders), although these were not well reported. INTERPRETATION: Psychiatric comorbidities are highly prevalent in the presentation of paediatric hypothalamic hamartoma. The aetiology of psychopathology comprises a range of interacting biological and psychosocial factors with particular influence from epilepsy. Further research is required to achieve an evidence base for treatment. WHAT THIS PAPER ADDS: Over half of children with hypothalamic hamartoma present with psychiatric comorbidity. Externalizing and internalizing disorders are present in approximately 60% and 30% of children with hypothalamic hamartomas respectively. Epilepsy and male sex are associated with externalizing psychopathology. Intellectual disability mediates the association between epilepsy and externalizing symptoms. No clear associations are evident for internalizing disorders or precocious puberty.

MÉTODO: En este estudio analizamos retrospectivamente las notas de los casos de todos los individuos con hamartoma hipotalámicos referidos al Great Ormond Street Hospital, London, entre el 2000 y 2016. Además, realizamos una revisión bibliográfica sistemática dirigida a identificar la serie de casos pediátricos. Síntomas psiquiátricos, demográfico, comorbilidades físicas y funcionamiento cognitivo fueron recolectados en todos los casos posibles.Se efectuaron análisis para determinar qué factores se asociaron con psicopatología y se investigaron mecanismos potenciales. RESULTADOS: En total 46 casos fueron incluidos en la serie de casos (28 masculinos, 18 femeninos, media de edad a la evaluación 11 años y 8 meses, DS 4 años y 0 mes). La revisión bibliográfica identifico 29 artículos describiendo 264 casos que reunieron criterios de inclusión para la extracción de datos. En total, al menos 50% de casos presentaban psicopatología. Epilepsia, discapacidad intelectual, y sexo masculino fueron asociados con desórdenes externos (déficit de atención con hiperactividad, desórdenes conductuales y oposicional desafiante, ataques de furia). Ningún factor fue asociado con la internalización de desórdenes neuropsiquiátricos (desórdenes de ansiedad y depresión), aunque éstos no fueron bien reportados. INTERPRETACIÓN: Las comorbilidades psiquiátricas son altamente prevalentes en la presentación del hamartoma hipotalámico pediátrico. La etiología de la psicopatología comprende un rango de interacciones biológicas y factores psicosociales con particular influencia de la epilepsia. Se requiere más información de investigación para reunir evidencia científica que guie el tratamiento.

MÉTODO: Nós analisamos retrospectivamente os registros de casos de todos os indivíduos encaminhados para o Hospital Great Ormond Street, Londres, entre 2000 e 2016. Além disso, uma revisão sistemática visando identificar todos os casos pediátricos prévios foi realizada. Sintomas psiquiátricos, dados demográficos, comorbidades físicas, e funcionamento cognitivo foram registrados para todos os casos em que foi possível. Análises foram realizadas para determinar quais fatores se associavam com psicopatologia e potenciais mecanismos foram investigados. RESULTADOS: Quarenta e seis casos foram incluídos na série de casos (28 do sexo masculino, 18 do sexo feminino; média de idade na avaliação 11a 8m (1a 11m-16a 11m, DP 4a 0m). Vinte e nove artigos representando dados de 264 casos atenderam aos critérios de inclusão para a revisão sistemática. No total, pelo menos 50% dos casos apresentaram psicopatologia. Epilepsia, deficiência intelectual, e sexo masculino eram associados com desordens externalizantes (transtorno de déficit de atenção e hiperatividade, transtornos de conduta e de desafio oposicional, e ataques de raiva). A deficiência intelectual mediou os efeitos da epilepsia e da psicopatologia externalizante. Nenhum fator foi associado com transtornos internalizantes (ansiedade e transtornos depressivos), embora estes não tenham sido bem reportados. INTERPRETAÇÃO: Comorbidades psiquiátricas são altamente prevalentes na apresentação do hamartoma hipotalâmico pediátrico. A etiologia da psicopatologia envolve uma variedade de fatores biológicos e psicossociais que interagem, com particular influência da epilepsia. Mais pesquisas são necessárias para se atingir uma base de evidências para o tratamento.

The Indianapolis Vocational Intervention Program: a cognitive behavioral approach to addressing rehabilitation issues in schizophrenia.

Despite wishing to return to productive activity, many individuals with schizophrenia enter rehabilitation with severe doubts about their abilities. Negative beliefs in schizophrenia have been linked with poorer employment outcome. Accordingly, in this paper, we describe efforts to synthesize vocational and cognitive behavior therapy interventions into a 6-month manualized program to assist persons with schizophrenia spectrum disorders overcome negative beliefs and meet vocational goals. This program, the Indianapolis Vocational Intervention Program (IVIP), includes weekly group and individual interventions and is intended as an adjunct to work therapy programs. The IVIP was initially developed over a year of working with 20 participants with Structured Clinical Interview for the Diagnostic and Statistical Manual-I (SCID-I) confirmed diagnoses of schizophrenia or schizoaffective disorder who were actively engaged in 20 hours per week of work activity. For this paper, we explain the development of the treatment manual and the group and individual interventions and present case examples that illustrate how persons with severe mental illness might utilize the manualized intervention.

Attributional style and symptoms as predictors of social function in schizophrenia.

While the attributions of people with schizophrenia have been hypothesized to play a role in determining social behavior, contradictory predictions can be made about exactly what type of attributions contribute to social dysfunction. One possibility is that attributing undesirable events to internal, stable, and global factors might lead to poorer social function. An alternate possibility is that attributing events in general to internal, stable, and global factors might lead to better social function. As a test of these hypotheses, 40 participants in a post-acute phase of schizophrenia were administered the Attributional Style Questionnaire, the Positive and Negative Syndrome Scale, and the Quality of Life Scale. Stepwise multiple regressions controlling for age and education indicated that a lack of negative symptoms and the tendency to make stable attributions for life events in general predicted more frequent social contacts, a higher quality of social interaction, and better community participation on the Quality of Life Scale. Results suggest that the tendency to see life events as the result of unstable or unpredictable causes is associated with social dysfunction independent of symptom level.

Heightened interpersonal dependency in schizophrenia: associations with graver impairment in neurocognition but not with negative or positive symptoms.

This study sought to clarify how dependency traits may be related to neurocognition and clinical symptoms of schizophrenia. Participants were 35 persons diagnosed with a schizophrenia-spectrum disorder who were recruited from a comprehensive day hospital at a VA Medical Center. Neurocognition, symptoms and level of interpersonal dependency were measured. Multiple regression analyses demonstrated that greater neurocognitive deficits predicted greater dependency needs. No relationship was found between symptoms and the level of dependency needs.

Neurocognitive deficits and history of childhood abuse in schizophrenia spectrum disorders: associations with Cluster B personality traits.

Cluster B personality traits have been detected in persons with schizophrenia, at a rate exceeding that of the general population. Unclear, however, is how to account for such high rates of Cluster B traits. Accordingly, this study explored the hypothesis that the presence of these traits may be linked to impairments in neurocognition, and childhood abuse history. To test this, we simultaneously obtained an assessment of Cluster B traits using the Millon Clinical Multiaxial Inventory III, along with measures of attention, verbal memory, affect recognition, executive function and childhood abuse history among 37 persons with schizophrenia spectrum disorders in a post acute phases of illness. Pearson correlation coefficients revealed that higher levels of histrionic and narcissistic traits were related to poorer neurocognition while higher levels of narcissistic traits were negatively correlated with childhood physical abuse. Higher levels of borderline traits were uniquely related to the report of childhood sexual abuse while higher levels of antisocial traits were related to higher levels of childhood physical abuse. Theoretical and clinical implications are discussed.

Patterns of obsessive-compulsive symptoms and social function in schizophrenia.

Research has alternately found that obsessive and compulsive (OC) symptoms in schizophrenia are associated with graver and lesser levels of negative symptoms. One possible explanation is that there are two distinct groups of persons with OC symptoms: those with cognitive deficits and high levels of negative symptoms and those who generally function well and have low levels of negative symptoms. To examine this question, we performed a cluster analysis on 66 persons with schizophrenia spectrum disorders on the basis of their level of obsessive-compulsive phenomena and global psychosocial function. Four groups were found: high OC/good function (n=9), non-OC/poor function (n=25), non-OC/moderate function (n=20), and high OC/poor function (n=12). A MANCOVA controlling for age found significant group differences on assessments of negative symptoms, executive function and attention among groups. As predicted, the high OC/poor function group had significantly poorer attention than any other group and poorer executive function than either non-OC group. The high OC/good function had lower levels of negative symptoms than either non-OC group. Implications for research and rehabilitation are discussed.

Vocational function among persons with schizophrenia with and without history of childhood sexual trauma.

This study examined whether history of childhood sexual abuse in schizophrenia is linked with severity of vocational deficits. Work performance was measured using the Work Behavior Inventory and hours of work performed in a vocational rehabilitation program and then compared for 12 participants with schizophrenia or schizoaffective disorder reporting abuse and 18 with schizophrenia with no abuse history. ANOVAs indicated that the sexual abuse group worked fewer hours during the first 4 weeks of the program and demonstrated poorer work performance overall. An interaction was found suggesting that the sexually abused group's performance declined as the nonsexually abused group improved over time. Childhood sexual abuse may be associated with greater vocational deficits in adults with schizophrenia.

Narrative transformation as an outcome in the psychotherapy of schizophrenia.

Assertions that changes or transformations in narratives contribute significantly to recovery from schizophrenia persist as a cornerstone of some psychotherapies. Yet when narrative transformation occurs in schizophrenia, what is there about the client's story that tangibly changes, and how might that be measured? To address this issue, we review literature on the importance of narrative transformation and identify narrative qualities that might theoretically change. We then report content and thematic analyses of the qualities of narratives that might potentially change over 14 months of psychotherapy. These analyses suggest that narratives in schizophrenia may gain complexity and dynamism, but the changes do not entail the creation of a new story or the 'awakening' of an 'old' self. From these analyses, the hypothesis that narrative transformation may occur in terms of growth in the richness of the internal dialogue that produces narrative is posed for future research.

Neuroticism and visual memory impairments as predictors of the severity of delusions in schizophrenia.

This study examined whether levels of emotional distress and impairments in visual memory were uniquely associated with severity of delusions in schizophrenia. Severity of delusions was assessed using select items from the positive component of the Positive and Negative Syndrome Scale among 44 persons with schizophrenia or schizoaffective disorder in a post-acute phase of illness. Emotional distress was assessed using the neuroticism subscale of the NEO Five Factor Inventory, and visual memory was assessed using the Rey Complex Figure Test. Controlling for executive function, visual attention, and verbal memory, a multiple regression analysis revealed that visual memory and neuroticism were each significantly related to severity of delusions, with the two combined accounting for one quarter of the variance. These same variables were unrelated to negative and excitement symptoms. Severity of delusions is linked to both higher levels of neuroticism and greater impairment in visual memory.

Social cognition and neurocognitive deficits in schizophrenia.

While research equivocally supports a relationship between social cognition and neurocognition, it is less clear whether social cognition is related to general cognitive functioning or whether specific aspects of social cognition are linked with specific forms of neurocognition. Thus, this study sought to investigate the relationships between various domains of neurocognition and two forms of social cognition, social cue recognition and social problem solving, for 40 people with schizophrenia spectrum disorders. Step-wise multiple regressions found that performance on neurocognitive tests was able to predict 47% and 38% of the variance on measures of the ability to recognize actual and suggested social cues, respectively, and 13% of participants' ability to problem solve in ambiguous social situations. Once estimated intelligence and hospitalization history were controlled, however, neurocognition no longer significantly predicted social problem solving. Executive functioning was uniquely related to each type of social cue recognition, while memory predicted only the recognition of concrete social cues.
