The Effect of Intrauterine Growth Restriction on Long-Term Outcome in Very or Extremely Low Birth Weight Infants

The project consisted of two long-term follow-up studies of preterm children addressing the question whether intrauterine growth restriction affects the outcome. Assessment at 5 years of age of 203 children with a birth weight less than 1000 g born in Finland in 1996-1997 showed that 9% of the children had cognitive impairment, 14% cerebral palsy, and 4% needed a hearing aid. The intelligence quotient was lower (p<0.05) than the reference value. Thus, 20% exhibited major, 19% minor disabilities, and 61% had no functional abnormalities. Being small for gestational age (SGA) was associated with sub-optimal growth later. In children born before 27 gestational weeks, the SGA had more neuropsychological disabilities than those appropriate for gestational age (AGA). In another cohort with birth weight less than 1500 g assessed at 5 years of age, echocardiography showed a thickened interventricular septum and a decreased left ventricular end-diastolic diameter in both SGA and AGA born children. They also had a higher systolic blood pressure than the reference. Laser-Doppler flowmetry showed different endothelium-dependent and -independent vasodilation responses in the AGA children compared to those of the controls. SGA was not associated with cardio-vascular abnormalities. Auditory event-related potentials (AERPs) were recorded using an oddball paradigm with frequency deviants (standard tone 500 Hz and deviant 750-Hz with 10% probability). At term, the P350 was smaller in SGA and AGA infants than in controls. At 12 months, the automatic change detection peak (mismatch negativity, MMN) was observed in the controls. However, the pre-term infants had a difference positivity that correlated with their neurodevelopment scores. At 5 years of age, the P1-deflection, which reflects primary auditory processing, was smaller, and the MMN larger in the preterm than in the control children. Even with a challenging paradigm or a distraction paradigm, P1 was smaller in the preterm than in the control children. The SGA and AGA children showed similar AERP responses. Prematurity is a major risk factor for abnormal brain development. Preterm children showed signs of cardiovascular abnormality suggesting that prematurity per se may carry a risk for later morbidity. The small positive amplitudes in AERPs suggest persisting altered auditory processing in the preterm in-fants.

Plasma brain-derived neurotrophic factor levels, learning capacity and cognition in patients with first episode psychosis

Background: Cognitive impairments are seen in first psychotic episode (FEP) patients. The neurobiological underpinnings that might underlie these changes remain unknown. The aim of this study is to investigate whether Brain Derived Neurotrophic Factor (BDNF) levels are associated with cognitive impairment in FEP patients compared with healthy controls. Methods: 45 FEP patients and 45 healthy controls matched by age, gender and educational level were selected from the Basque Country area of Spain. Plasma BDNF levels were assessed in healthy controls and in patients. A battery of cognitive tests was applied to both groups, with the patients being assessed at 6 months after the acute episode and only in those with a clinical response to treatment. Results: Plasma BDNF levels were altered in patients compared with the control group. In FEP patients, we observed a positive association between BDNF levels at six months and five cognitive domains (learning ability,immediate and delayed memory, abstract thinking and processing speed) which persisted after controlling for medications prescribed, drug use, intelligence quotient (IQ) and negative symptoms. In the healthy control group, BDNF levels were not associated with cognitive test scores. Conclusion: Our results suggest that BDNF is associated with the cognitive impairment seen after a FEP. Further investigations of the role of this neurotrophin in the symptoms associated with psychosis onset are warranted.

Cognitive deficits in alcoholism

Contexte : Les répercussions de l’alcool au niveau des fonctions cognitives sont bien documentées. Certaines hypothèses suggèrent que l’alcool affecte des fonctions cognitives spécifiques alors que d’autres avancent l’hypothèse de déficits diffus. Cependant, une ambigüité persiste concernant quelles fonctions cognitives sont le plus touchées par l’alcool, et à quel point la durée d’abstinence affecte la récupération cognitive. Nous avons procédé à une des premières méta-analyses qui s’intéresse aux différentes fonctions cognitives touchées par la consommation problématique d’alcool et à la durée d’abstinence requise pour une récupération au niveau des cognitions. Méthodes : Une recherche de la littérature a permis d’identifier 62 études évaluant les cognitions chez les personnes présentant des troubles liés à l’utilisation d’alcool. Les estimations de la taille d’effet ont été calculées avec la Comprehensive Meta Analysis –V2 pour les 12 domaines cognitifs suivants : quotient intellectuel, fluidité verbale/langage, vitesse de traitement de l’information, mémoire de travail, attention, résolution de problème/fonctions exécutives, inhibition/impulsivité, apprentissage verbal, mémoire verbale, apprentissage visuel, mémoire visuelle, habiletés visuo-spatiales. Parmi ces 12 domaines cognitifs, 3 estimations de la taille d’effet ont été calculées selon les durées d’abstinences suivantes : court- (<1 mois), moyen- (2 à 12 mois) et long- (>1 an) termes. Résultats : Les résultats ont révélé la présence de dysfonctions modérées dans 11 domaines cognitifs durant l’abstinence à court terme, et dans 10 domaines cognitifs pour le moyen-terme. Des dysfonctions cognitives minimales furent notées durant l’abstinence à long-terme. Conclusions : Ces résultats révèlent des déficits cognitifs significatifs et diffus durant la première année d’abstinence. Déficits qui se normalisent après un an. Ces résultats soutiennent l’hypothèse de déficits cognitifs diffus reliés à l’alcoolisme et suggèrent que la cognition devrait faire partie intégrante du traitement d’alcoolisme.

Estudio de caso: perfil neuropsicológico de joven con Síndrome de Williams-Beuren

El síndrome de Williams-Beuren (SWB) es definido como una condición genética cuyo patrón cognitivo se caracteriza principalmente por la presencia de retardo mental leve a moderado, un bajo desempeño en tareas relacionadas con las funciones viso-espaciales y un alto rendimiento en funciones del lenguaje. A pesar de lo anterior, hoy en día no existe un acuerdo general en cuanto al perfil neuropsicológico específico de esta condición en vista del carácter heterogéneo de los cuadros clínicos estudiados en previas investigaciones. El objetivo del presente estudio es realizar una evaluación neuropsicológica a una joven diagnosticada con SWB, para explorar el perfil neuropsicológico y tener una mejor comprensión de las manifestaciones cognitivas de esta condición. Lo anterior teniendo en cuenta los nuevos paradigmas de la discapacidad intelectual, describiendo tanto las debilidades como las fortalezas de las personas con esta condición. Los resultados obtenidos a partir de la evaluación neuropsicológica consistieron fundamentalmente en la conservación de procesos atencionales de tipo auditivo, memoria declarativa explícita anterógrada en rango normal, lenguaje del polo receptivo y motor conservado, un coeficiente intelectual (CI) en 72, ubicado en rango inferior, denotando una inteligencia límite, alteración en habilidades viso-espaciales, limitaciones en funciones ejecutivas, principalmente en planeación y razonamiento abstracto. Lo anterior confirmaría algunos de los aspectos cognitivos señalados en estudios precedentes.

La evaluación educativa Monitor y el sistema de evaluación de Hungría.

Después de una primera evaluación educativa nacionalizada en los años cincuenta y pasando por la evaluación realizada en 1980, denominada Tof-80, se establece en Hungría un proceso sistemático de evaluación denominado monitor. Este se encuentra a medias entre la clásica evaluación psicométrica del cociente intelectual y la más característica evaluación de conocimientos específicos propios de estas pruebas, se centra en las áreas de matemáticas, lectura e informática y busca tanto la comparación diacrónica como sincrónica. Es una evaluación no sólo individual sino también grupal. El sistema actual de evaluación húngaro fue aprobado en 1999. así, el examen realizado al terminar secundaria y los de acceso a la universidad son administrados de forma centralizada y son independientes de los centros. El objetivo principal ha sido garantizar la igualdad a la hora de realizar estudios superiores tanto en los conocimientos generales como en los específicos de cada área que se desee estudiar. El principio de iguald.

Innovation, talent attraction and retention

The success of an organization isn’t, in most cases, only shown trough their profits. Today the value of a company, with respect to its market value exceeds their financial quality. Intellectual capital is a major share in the value of the company. Managing employees with an emphasis on intellectual capital and talent is an emergency that arises in the path of human resource managers. The definition of intellectual capital and talent, leads us, first, to a high IQ (Intelligence Quotient), good schools and / or university results. But the intellectual capital and talent of an employee must be linked to his ability, to high performance and good results. How to manage, attract and keep these employees in organizations is also something that requires talent. Now, the basic skills of employees aren’t sufficient for competitive companies. There are currently required higher levels of skills, because there are a growing number of activities that involve "knowledge work". Most companies in the world have a great challenge for the coming years: the challenge of scarcity of talent. The most competitive companies will be those that have the most talented employees. In terms of originality, this paper aims to create discussion about the relationship between talent attraction, talent retention and innovation, as drivers of business competitiveness. The research is based on the categorization methodology defined by Yin (2003) as single case study carried out in a company that is specialized in high precision components.The findings presented here show a strong link between talents attraction, talents retention and innovation.

The relation of E.Q and I.Q. to learning from the standard self-instructional programs in spelling and english

This paper reviews a study that was done with hearing and hearing impaired children to test the effectiveness of self-instructional programs and whether the results can be correlated with Educational Quotient and Intelligence Quotient.

The untethered facilities manager

Facilities managers have a host of skills to sustain the functionality of complex buildings, often not provided by them directly, but by the team of specialists they draw upon to effectively plan for the future, whether the resource be money, space or technology. Building intelligence presents a challenge in terms of understanding a wholly new approach to the building management. This paper asks if the intelligent building of today meets the needs of the facilities management team. Does it enable them to manage their asset more effectively? New technologies are converging that will enable a radically new approach to maintenance, enabling remote smart sensing or remote condition based monitoring (CBM). Some of the design and economic issues that arise from this radically new approach to managing built assets are highlighted and the possibilities for a maintenance environment, where wires, power cables and data loggers become a thing of the past, is described.

Learning and memory in holocaust survivors with posttraumatic stress disorder

Background: Impairments in explicit memory have been observed in Holocaust survivors with posttraumatic stress disorder. Methods: To evaluate which memory components are preferentially affected, the California Verbal Learning Test was administered to Holocaust survivors with (n = 36) and without (n = 26) posttraumatic stress disorder, and subjects not exposed to the Holocaust (n = 40). Results: Posttraumatic stress disorder subjects showed impairments in learning and short-term and delayed retention compared to nonexposed subjects; survivors without posttraumatic stress disorder did not. Impairments in learning, but not retention, were retained after controlling fir intelligence quotient. Older age was associated with poorer learning and memory performance in the posttraumatic stress disorder group only. Conclusions: The most robust impairment observed in posttraumatic stress disorder was in verbal learning, which may be a risk factor for or consequence of chronic posttraumatic stress disorder. The negative association between performance and age may reflect accelerated cognitive decline in posttraumatic stress disorder.

Prevalence of disorders of the autism spectrum in a population cohort of children in South Thames: the special needs and autism project (SNAP)

Background Recent reports have suggested that the prevalence of autism and related spectrum disorders (ASDs) is substantially higher than previously recognised. We sought to quantify prevalence of ASDs in children in South Thames, UK. Methods Within a total population cohort of 56946 children aged 9-10 years, we screened all those with a current clinical diagnosis of ASD (n=255) or those judged to be at risk for being an undetected case (n=1515). A stratified subsample (n=255) received a comprehensive diagnostic assessment, including standardised clinical observation, and parent interview assessments of autistic symptoms, language, and intelligence quotient (IQ). Clinical consensus diagnoses of childhood autism and other ASDs were derived. We used a sample weighting procedure to estimate prevalence. Findings The prevalence of childhood autism was 38.9 per 10000 (95% CI 29.9-47.8) and that of other ASDs was 77.2 per 10000 (52.1-102.3), making the total prevalence of all AS Ds 116.1 per 10000 (90.4-141.8). A narrower definition of childhood autism, which combined clinical consensus with instrument criteria for past and current presentation, provided a prevalence of 24.8 per 10 000 (17.6-32.0). The rate of previous local identification was lowest for children of less educated parents. Interpretation Prevalence of autism and related ASDs is substantially greater than previously recognised. Whether the increase is due to better ascertainment, broadening diagnostic criteria, or increased incidence is unclear. Services in health, education, and social care will need to recognise the needs of children with some form of ASD, who constitute 1% of the child population.

Gut permeability in autism spectrum disorders

Objective To test whether gut permeability is increased in autism spectrum disorders (ASD) by evaluating gut permeability in a population-derived cohort of children with ASD compared with age- and intelligence quotient-matched controls without ASD but with special educational needs (SEN). Patients and Methods One hundred thirty-three children aged 10–14 years, 103 with ASD and 30 with SEN, were given an oral test dose of mannitol and lactulose and urine collected for 6 hr. Gut permeability was assessed by measuring the urine lactulose/mannitol (L/M) recovery ratio by electrospray mass spectrometry-mass spectrometry. The ASD group was subcategorized for comparison into those without (n = 83) and with (n = 20) regression. Results There was no significant difference in L/M recovery ratio (mean (95% confidence interval)) between the groups with ASD: 0.015 (0.013–0.018), and SEN: 0.014 (0.009–0.019), nor in lactulose, mannitol, or creatinine recovery. No significant differences were observed in any parameter for the regressed versus non-regressed ASD groups. Results were consistent with previously published normal ranges. Eleven children (9/103 = 8.7% ASD and 2/30 = 6.7% SEN) had L/M recovery ratio > 0.03 (the accepted normal range cut-off), of whom two (one ASD and one SEN) had more definitely pathological L/M recovery ratios > 0.04. Conclusion There is no statistically significant group difference in small intestine permeability in a population cohort-derived group of children with ASD compared with a control group with SEN. Of the two children (one ASD and one SEN) with an L/M recovery ratio of > 0.04, one had undiagnosed asymptomatic celiac disease (ASD) and the other (SEN) past extensive surgery for gastroschisis.

Good lives sexual offender treatment for mentally disordered offenders

Purpose – The main aim of this paper is to describe the content, structure and preliminary evaluation of a new Good Lives sexual offender treatment group (SOTG) for male mentally disordered offenders.

Design/methodology/approach – As evaluation and work on the SOTG is necessarily ongoing, case study descriptions of each patient who attended the SOTG and of their progress throughout SOTG are described.

Findings – Overall, the case study progress reports suggest that mentally disordered male patients made some notable progress on SOTG despite their differential and complex needs. In particular, attention to each patient's life goals and motivators appeared to play a key role in promoting treatment engagement. Furthermore, patients with lower intelligence quotient and/or indirect pathways required additional support to understand the links between the Good Lives Model (GLM) and their own risk for sexual offending.

Research limitations/implications – Further evaluations of SOTG groups, that incorporate higher numbers of participants and adequate control groups, are required before solid conclusions and generalisations can be made.

Practical implications – Practitioners should consider providing additional support to clients when implementing any future SOTGs for mentally disordered patients.

Originality/value – This is the first paper to outline and describe implementation of the GLM in the sexual offender treatment of mentally disordered male patients group format. As such, it will be of interest to any professionals involved in the facilitation of sexual offender treatment within this population.

An examination of the influence of maternal depression trajectories on child cognitive development and adolescent psychotic experiences

 This thesis investigated trajectories of maternal depression over time, and their influence on offspring's cognitive development in childhood and subsequent risk of psychotic experiences in early adolescence. Offspring’s IQ was also examined as a potential mediator of the relationship between maternal depression and offspring’s risk of psychotic experiences.

A review of vulnerability and risks for schizophrenia: beyond the two hit hypothesis

Schizophrenia risk has often been conceptualized using a model which requires two hits in order to generate the clinical phenotype-the first as an early priming in a genetically predisposed individual and the second a likely environmental insult. The aim of this paper was to review the literature and reformulate this binary risk-vulnerability model. We sourced the data for this narrative review from the electronic database PUBMED. Our search terms were not limited by language or date of publication. The development of schizophrenia may be driven by genetic vulnerability interacting with multiple vulnerability factors including lowered prenatal vitamin D exposure, viral infections, smoking intelligence quotient, social cognition cannabis use, social defeat, nutrition and childhood trauma. It is likely that these genetic risks, environmental risks and vulnerability factors are cumulative and interactive with each other and with critical periods of neurodevelopmental vulnerability. The development of schizophrenia is likely to be more complex and nuanced than the binary two hit model originally proposed nearly thirty years ago. Risk appears influenced by a more complex process involving genetic risk interfacing with multiple potentially interacting hits and vulnerability factors occurring at key periods of neurodevelopmental activity, which culminate in the expression of disease state. These risks are common across a number of neuropsychiatric and medical disorders, which might inform common preventive and intervention strategies across non-communicable disorders.

Autonomy Markers in Brazilian Adults With Intellectual Disabilities

The objective of the study was to investigate the relationship between autonomy markers in adult people with intellectual disabilities (ID) and variables such as intelligence quotient (IQ), early aging, and literacy. Participants were 47 adults with ID (33 men; aged 28-58 years with nonspecific etiology, 34 literate). All participants were trainees at the Center for Training of Capacity and Orientation for Employment at Associação de Pais e Amigos dos Excepcionais de São Paulo, São Paulo State, Brazil. They were divided into two age groups: younger (n = 27, mean age 31.85; +/- 2.23), and older (n = 38, mean age 41.84; +/- 5.54). They were administered intelligence scales twice, and answered questions related to social participation, community integration, and choice-making; the percentage of item responses leaning toward self-determination and freedom in choice-making was considered in defining the autonomy score. For both groups, IQ declined from the first to the second assessment. Autonomy scores were more determined by IQ classification than by literacy. Authors concluded that autonomy in people with ID is a multifactorial phenomenon associated with cognitive decline.
