The Ethics Of Placebo-Controlled Trials In Developing Countries To Prevent Mother-To-Child Transmission Of Hiv, John N. Williams Dec 2010

The Ethics Of Placebo-Controlled Trials In Developing Countries To Prevent Mother-To-Child Transmission Of Hiv, John N. Williams

John N. WILLIAMS

Placebo-trials on HIV-infected pregnant women in developing countries like Thailand and Uganda have provoked recent controversy. Such experiments aim to find a treatment that will cut the rate of vertical transmission more efficiently than existing treatments like zidovudine. This scenario is first stated as generally as possible, before three ethical principles found in the Belmont Report, itself a sharpening of the Helsinki Declaration, are stated. These three principles are the Principle of Utility, the Principle of Autonomy and the Principle of Justice. These are taken as voices of moral imperative. But although each has intuitive appeal, it can be shown …


Bimanual Reaching Across The Hemispace: Which Hand Is Yoked To Which?, Gavin Buckingham, Gordon Binsted, David Carey Nov 2010

Bimanual Reaching Across The Hemispace: Which Hand Is Yoked To Which?, Gavin Buckingham, Gordon Binsted, David Carey

Gavin Buckingham

When both hands perform concurrent goal-directed reaches, they become yoked to one another. To investigate the direction of this coupling (i.e., which hand is yoked to which), the temporal dynamics of bimanual reaches were compared with equivalent-amplitude unimanual reaches. These reaches were to target pairs located on either the left or right sides of space; meaning that in the bimanual condition, one hand's contralateral (more difficult) reach accompanied by the other hand's ipsilateral (easier) reach. By comparing which hand's difficult reach was improved more by the presence of the other hand's easier ipsilateral reach, we were able to demonstrate asymmetries …

Charles A. Sanislow, Ph.D.

Objective: To examine prospectively the course of major depressive disorder (MDD) and to test for the moderating effects of personality disorder (PD) comorbidity on relapse after remission from an episode of MDD.

Method: Participants were 303 patients (196 women and 107 men) with current DSM-IV diagnosed MDD at baseline enrollment in the Col­laborative Longitudinal Personality Disorders Study. Major depressive disorder and Axis I psychiatric disorders were assessed with the Structured Clinical Interview for DSM-IV, and Axis II PDs were assessed with the Diagnostic Interview for DSM-IV Personality Disorders. The course of MDD was assessed with the Longitudinal Interval Follow­up Evaluation …


Developing Constructs For Psychopathology Research: Research Domain Criteria, Charles A. Sanislow, Daniel S. Pine, Kevin J. Quinn, Michael J. Kozak, Marjorie A. Garvey, Robert K. Heinssen, Philip Sung-En Wang, Bruce N. Cuthbert Oct 2010

Developing Constructs For Psychopathology Research: Research Domain Criteria, Charles A. Sanislow, Daniel S. Pine, Kevin J. Quinn, Michael J. Kozak, Marjorie A. Garvey, Robert K. Heinssen, Philip Sung-En Wang, Bruce N. Cuthbert

Charles A. Sanislow, Ph.D.

There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple disruptions in putative mechanistic factors (e.g., excessive fear, deficient impulse control), and different disrupted mechanisms appear to play major roles in many disorders. The Research Domain Criteria (RDoC) framework is a heuristic to facilitate the incorporation of behavioral neuroscience in the study of psychopathology. Such integration might be achieved by shifting the central research focus …


Psychometric Characteristics And Clinical Correlates Of Neo-Pi-R Fearless Dominance And Impulsive Antisociality In The Collaborative Longitudinal Personality Disorders Study, Edward A.

Psychometric Characteristics And Clinical Correlates Of Neo-Pi-R Fearless Dominance And Impulsive Antisociality In The Collaborative Longitudinal Personality Disorders Study, Edward A. Witt, Christopher J. Hopwood, Leslie C. Morey, John C. Markowitz, Thomas H. Mcglashan, Carlos M. Grilo, Charles A. Sanislow, M. Tracie Shea, Andrew E. Skodol, John G. Gunderson, M. Brent Donnellan

Charles A. Sanislow, Ph.D.

This study evaluates the validity of derived measures of the psychopathic personality traits of Fearless Dominance and Impulsive Antisociality from the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992) using data from the Collaborative Longitudinal Personality Disorders Study (baseline N = 733). These 3 issues were examined: (a) the stability of the measures over a 10-year interval, (b) their criterion-related validity, and (c) their incremental validity relative to an alternative NEO-PI-R profile-rating approach for assessing psychopathy. NEO-PI-R Fearless Dominance and Impulsive Antisociality scales were relatively stable across 10 years and demonstrated differential associations with measures of personality pathology and psychopathology …


Helping Prostate Cancer Patients Understand The Causes Of Anxiety And Depression: Comparing Cancer-Caused Vs Patient Response Events, Christopher Sharpley, Vicki Bitsika, David Christie Aug 2010

Helping Prostate Cancer Patients Understand The Causes Of Anxiety And Depression: Comparing Cancer-Caused Vs Patient Response Events, Christopher Sharpley, Vicki Bitsika, David Christie

Vicki Bitsika

Background: Prostate cancer (PCa) patients have elevated anxiety and depression, often showing impairments in decision-making and weakened relationships with their partner and family. Although treatment for these psychological side-effects of PCa is strongly recommended, relatively little is known of the causal processes underlying them. This study compared cancer-based lifestyle changes vs patient behavioural responses to cancer as predictors of anxiety and depression among PCa patients. Methods: PCa patients (381) were surveyed for their responses to standardised anxiety and depression questionnaires, plus a questionnaire designed to assess the kinds of lifestyle changes that had occurred to them and their responses to …


The Influence Of Competing Perceptual And Motor Priors In The Context Of The Size-Weight Illusion, Gavin Buckingham, Melvyn Goodale Jul 2010

The Influence Of Competing Perceptual And Motor Priors In The Context Of The Size-Weight Illusion, Gavin Buckingham, Melvyn Goodale

Gavin Buckingham

When lifting objects of identical mass but different sizes, people perceive the smaller objects as weighing more than the larger ones (the 'size-weight' illusion, SWI). While individual's grip and load force rates are rapidly scaled to the objects' actual mass, the magnitude of the force used to lift these SWI-inducing objects is rarely discussed. Here, we show that participants continue to apply a greater loading force to a large SWI-inducing cube than to a small SWI cube, lift after lift. These differences in load force persisted long after initial errors in grip and load force rates had been corrected. Interestingly, …


Plasma Prekallikrein Levels Are Positively Associated With Circulating Lipid Levels And The Metabolic Syndrome In Children., James A. Mackenzie, Kristen A. Roosa, Brooks B. Gump, Amy K. Dumas, Kestutis G. Bendinskas Jul 2010

Plasma Prekallikrein Levels Are Positively Associated With Circulating Lipid Levels And The Metabolic Syndrome In Children., James A. Mackenzie, Kristen A. Roosa, Brooks B. Gump, Amy K. Dumas, Kestutis G. Bendinskas

Brooks B. Gump

Plasma prekallikrein (PK) has been shown to be associated with cardiovascular disease (CVD) and its risk factors, but these associations have not been investigated in children. The present study examined PK activity in relation to well-established cardiovascular risk factors in a cohort of children aged 9–11 years (N = 97). We found a significant and positive association between PK and fasting levels of total cholesterol (p < 0.01), non-high-density lipoprotein cholesterol (p < 0.01), and triglycerides (p < 0.001). In addition, there was a significant association between PK activity and the metabolic syndrome, a clustering of risk factors considered to have an impact on atherosclerosis and CVD mortality. Finally, we found that children with a family history of CVD had significantly elevated PK activity. These novel findings warrant further investigations into the relationship between circulating PK levels and CVD risk factors because PK may be involved in the progression of the disease state. Il est bien connu que la pre´kallicre´ine (PK) est associe´e a` la maladie cardiovasculaire (CVD) et a` ses facteurs de risque, mais ces associations n’ont pas e´te´ ve´rifie´es chez les enfants. Cette e´tude se propose de ve´rifier l’association entre l’activite´ de la PK et les facteurs de risque de CVD aupre`s d’une cohorte d’enfants aˆge´s de 9 a` 11 ans (N = 97). On observe une corre´lation positive significative entre la PK et les variables suivantes : la concentration totale de choleste´rol a` jeun (p < 0,01), les concentrations des lipoprote´ines non a` haute densite´ (p < 0,01) et la concentration des triglyce´rides (p < 0,001). De plus, on observe une corre´lation significative entre l’activite´ de la PK et le syndrome me´tabolique constitue par un ensemble de facteurs ayant un effet sur l’athe´roscle´rose et la mortalite´ due a` la CVD. En dernier lieu, les enfants avec des ante´ce´dents familiaux de CVD pre´sentent une plus importante activite´ de la PK, et ce, de fac¸on significative. Ces premie`res observations sugge`rent d’autres e´tudes sur la relation entre la concentration sanguine de PK et les facteurs de risque de CVD, car la PK pourrait eˆtre implique´e dans la progression de la maladi


On The Number Of Trials Necessary For Stabilization Of Error-Related Brain Activity Across The Life Span, Jason Themanson, Matthew Pontifex, Mark Scudder, Michael Brown, Kevin O'Leary, Chien-Ting Wu, Charles Hillman Jun 2010

On The Number Of Trials Necessary For Stabilization Of Error-Related Brain Activity Across The Life Span, Jason Themanson, Matthew Pontifex, Mark Scudder, Michael Brown, Kevin O'Leary, Chien-Ting Wu, Charles Hillman

Jason R. Themanson, Ph.D

The minimum number of trials necessary to accurately characterize the error-related negativity (ERN) and the error positivity (Pe) across the life span was investigated using samples of preadolescent children, college-age young adults, and older adults. Event-related potentials and task performance were subsequently measured during a modified flanker task. Response-locked averages were created using sequentially increasing errors of commission in blocks of two. Findings indicated that across all age cohorts ERN and Pe were not significantly different relative to the within-participants grand average after six trials. Further, results indicated that the ERN and Pe exhibited excellent internal reliability in preadolescent children …

Archetypal Energies, "Psychic Politics", And The Transformative Potential Of The Health Care Debate, Carroy U. Ferguson Apr 2010

Archetypal Energies, "Psychic Politics", And The Transformative Potential Of The Health Care Debate, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

In a previous message, I spoke of “Archetypal Energies, The Emergence of Obama As A Practical Idealist, and Global Transformation” (February/March 2009). I suggested that at issue is what I called “psychic politics for global transformation, nurtured by practical idealism and the Archetypal Energies.” To reiterate, I have described Archetypal Energies as Higher Vibrational Energies, operating deep within our individual and collective psyches, which have their own transcendent value, purpose, quality, and “voice” unique to the individual. We experience them as “creative urges” to move us toward our Highest Good or Optimal Realities. I use easily recognized terms to evoke …

Charles A. Sanislow, Ph.D.

OBJECTIVE: The authors sought to determine whether personality disorders diagnosed during a depressive episode have long-term outcomes more typical of those of other patients with personality disorders or those of patients with noncomorbid major depression.

METHOD: The authors used 6-year outcome data collected from the multisite Collaborative Longitudinal Personality Disorders Study (CLPS). Diagnoses and personality measures gathered from the study cohort at the index assessment using interview and self-report methods were associated with symptomatic, functional, and personality measures at 6-year follow-up. Of 668 patients initially recruited to the CLPS, 522 were followed for 6 years. All participants had either a …

22. Young Children’S Emerging Ability To Make False Statements., Thomas D. Lyon, Elizabeth C. Ahern, Jodi A. Quas

Thomas D. Lyon

This study examined the origins of children’s ability to make consciously false statements, a necessary component of lying. Children 2 to 5 years of age were rewarded for claiming that they saw a picture of a bird when viewing pictures of fish. They were asked outcome questions (“Do you win/lose?”), recognition questions (“Do you have a bird/fish?”), and recall questions (“What do you have?”), which were hypothesized to vary in difficulty depending on the need for consciousness of falsity (less for outcome questions) and self-generation of an appropriate response (more for recall questions). The youngest children (21⁄2 to 31⁄2 years …

Amresh Srivastava

Duration of untreated psychosis (DUP) has emerged as a reliable predictor of outcome but continues to remain under scientific scrutiny. The present study examines the effect of differential periods of DUP on long-term outcome of first episode schizophrenia at Mumbai, India. This research was a prospective, 10-year follow-up naturalistic study. Hospitalized patients of first episode schizophrenia were selected and followed up. Results showed that the mean DUP was higher for a group which showed clinical recovery on Clinical Global Impression Scale [14.0 months (SD=8.0) in recovered and 10.8 months (SD=5.7) in non-recovered group (P=0.091)]. DUP was not found to be …

Brooks B. Gump

Heavy metal exposure in children has been associated with a variety of physiological and neurological problems. The goal of this study was to utilize proteomics to enhance the understanding of biochemical interactions responsible for the health problems related to lead and mercury exposure at concentrations well below CDC guidelines. Blood plasma and serum samples from 34 children were depleted of their most abundant proteins using antibody-based affinity columns and analyzed using two different methods, LC-MS/MS and 2-D electrophoresis coupled with MALDI-TOF/MS and tandem mass spectrometry. Apolipoprotein E demonstrated an inverse significant association with lead concentrations (average being one microgram/deciliter) as …


Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted Feb 2010

Gating Of Vibrotactile Detection During Visually Guided Bimanual Reaches, Gavin Buckingham, David Carey, Francisco Colino, John Degrosbois, Gordon Binsted

Gavin Buckingham

It is far more difficult to detect a small tactile stimulation on a finger that is moving compared to when it is static. This suppression of tactile information during motion, known as tactile gating, has been examined in some detail during single-joint movements. However, the existence and time course of this gating has yet to be examined during visually guided multi-joint reaches, where sensory feedback may be paramount. The current study demonstrated that neurologically intact humans are unable to detect a small vibratory stimulus on one of their index fingers during a bimanual reach toward visual targets. By parametrically altering …

14. Investigative Interviewing Of The Child., Thomas D. Lyon

Thomas D. Lyon

Children, if questioned in a supportive manner, are capable of providing enormous amounts of productive information in response to open-ended questions. The irony is that many direct and suggestive methods once thought necessary to overcome abused children's reluctance to disclose abuse have been found counterproductive in two ways: they minimize the number of details in true allegations at the same time that they increase the risk of false allegations.

21. Children’S Reasoning About Disclosing Adult Transgressions: Effects Of Maltreatment, Child Age, And Adult Identity., Thomas D. Lyon, Elizabeth C. Ahern, Lindsay A. Malloy, Jodi A. Quas

Thomas D. Lyon

A total of two hundred ninety-nine 4- to 9-year-old maltreated and nonmaltreated children of comparable socioeconomic status and ethnicity judged whether children should or would disclose unspecified transgressions of adults (instigators) to other adults (recipients) in scenarios varying the identity of the instigator (stranger or parent), the identity of the recipient (parent, police, or teacher), and the severity of the transgression (‘‘something really bad’’ or ‘‘something just a little bad’’). Children endorsed more disclosure against stranger than parent instigators and less disclosure to teacher than parent and police recipients. The youngest maltreated children endorsed less disclosure than nonmaltreated children, but …

Chapter Four: Parenting An Emerging Adult - 101, Varda Konstam Jan 2010

Chapter Four: Parenting An Emerging Adult - 101, Varda Konstam

Varda Konstam

Parents of emerging adults are exploring terra incognito. It’s not that there are no rules; it’s that the rules are obsolete. They no longer fit today’s realities. For reasons we’ve discussed (and for others that we will discuss), it’s just not as easy for emerging adults today to jump into the river of adulthood as it was for previous generations. That means parents are likely to remain active parents for longer than ever before. And most of us are pretty clueless about how to make it work. Anxiety is inevitable given the lack of guidance and certainty. However, we can …


The Biology Of Reality Testing - Implications For Cognitive Education, Neil Greenberg Jan 2010

The Biology Of Reality Testing - Implications For Cognitive Education, Neil Greenberg

Neil Greenberg

• This report explores the proposition that teaching effectiveness can be enhanced by accommodating the key differences between two complementary and deeply engrained modes of reality testing, each predominantly centered in different hemispheres of the brain. • (1) Correspondence involves “reality-testing” of a percept, the cerebral representation of an experience in the world. • (2) Coherence involves “textualizing”, that is, reality-testing of a percept by how easily it relates to previous and ongoing parallel and collateral experiences. • Confidence in the validity of any percept throughout development is related to the interplay of these key processes. • As organisms develop, …

Lifting Without Seeing: The Role Of Vision In Perceiving And Acting Upon The Size Weight Illusion, Gavin Buckingham, Melvyn Goodale Dec 2009

Lifting Without Seeing: The Role Of Vision In Perceiving And Acting Upon The Size Weight Illusion, Gavin Buckingham, Melvyn Goodale

Gavin Buckingham

BACKGROUND: Our expectations of an object's heaviness not only drive our fingertip forces, but also our perception of heaviness. This effect is highlighted by the classic size-weight illusion (SWI), where different-sized objects of identical mass feel different weights. Here, we examined whether these expectations are sufficient to induce the SWI in a single wooden cube when lifted without visual feedback, by varying the size of the object seen prior to the lift.

METHODOLOGY/PRINCIPAL FINDINGS: Participants, who believed that they were lifting the same object that they had just seen, reported that the weight of the single, standard-sized cube that they …
