Associations between the stanford integrated psychosocial assessment for transplant and one-year lung transplant medical and psychosocial outcomes.

The Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) is a standardized measure of the psychosocial risk profile of solid organ transplant candidates. While studies have found associations between this measure and transplant outcomes, to date this has not been examined in lung transplant recipients. We examined relations between pre-transplant SIPAT scores and 1-year lung transplant medical and psychosocial outcomes in a sample of 45 lung transplant recipients. The SIPAT was significantly associated with 6-minute walk test (χ2(1) = 6.47, p = .010), number of readmissions (χ2(1) = 6.47, p = .011), and mental health services utilization (χ2(1) = 18.15, p < .001). It was not a significantly associated with the presence of organ rejection or mortality (ps > 0.10). Results suggest that the SIPAT can help identify patients who are at an elevated risk for transplant complications and thus would benefit from services to mitigate risk factors and improve outcomes.

Characterization of the Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) in Lung Transplant Candidates.

The SIPAT is a standardized measure for pre-transplant psychosocial evaluation. Previous SIPAT studies utilized a relatively small lung transplant sample and only included listed patients. This study characterized the SIPAT in 147 lung transplant candidates to better elucidate its utility. The average score corresponded to a minimally acceptable rating and nearly half of the patients had relative or absolute contraindications. Interstitial Lung Disease (ILD) patients scored more favorably than non-ILD patients (U = 7.69, p < .05). The Total (ß = - .05, SE = .018, p < .01), Social Support Subscale (ß = - .133, SE = .058, p < .05), and Psychosocial Stability and Psychopathology Subscale (ß = - .103, SE = .040, p < .05) significantly predicted listing status. The SIPAT has a unique profile in lung transplant candidates and demonstrated utility for guiding transplant decisions. Future research should examine which lung transplant outcomes are significantly associated with SIPAT scores.

Practice Issues for Evaluation and Management of the Suicidal Left Ventricular Assist Device Patient.

There is a high prevalence of depression among left ventricular assist device patients, who present with an increased risk of suicidality given access to means via the device either with nonadherence or disconnection. Suicidality via device nonadherence/disconnection is an underresearched clinical issue, as paradoxically this life-saving procedure can also provide a method of lethal means to patients with significant mental health concerns. A case study is used to highlight the course of an attempted suicide by ventricular assistive device nonadherence. Clinical implications and recommendations for practice include a thorough psychological evaluation presurgery, monitoring quality of life and coping styles before and after placement, psychological testing, outlining specific suicide protocols, psychiatric care considerations for patients with highly specialized medical devices, and related ethical concerns.

Children with 7q11.23 duplication syndrome: psychological characteristics.

To begin to delineate the psychological characteristics associated with classic 7q11.23 duplication syndrome (duplication of the classic Williams syndrome region; hereafter classic Dup7), we tested 63 children with classic Dup7 aged 4-17 years. Sixteen toddlers aged 18-45 months with classic Dup7 and 12 adults identified by cascade testing also were assessed. For the child group, median General Conceptual Ability (similar to IQ) on the Differential Ability Scales-II was 85.0 (low average), with a range from severe disability to high average ability. Median reading and mathematics achievement standard scores were at the low average to average level, with a range from severe impairment to high average or superior ability. Adaptive behavior was considerably more limited; median Scales of Independent Behavior-Revised Broad Independence standard score was 62.0 (mild impairment), with a range from severe adaptive impairment to average adaptive ability. Anxiety disorders were common, with 50.0% of children diagnosed with Social Phobia, 29.0% with Selective Mutism, 12.9% with Separation Anxiety Disorder, and 53.2% with Specific Phobia. In addition, 35.5% were diagnosed with Attention Deficit/Hyperactivity Disorder and 24.2% with Oppositional Defiant Disorder or Disruptive Behavior Disorder-Not Otherwise Specified. 33.3% of the children screened positive for a possible Autism Spectrum Disorder and 82.3% were diagnosed with Speech Sound Disorder. We compare these findings to previously reported results for children with Williams syndrome and argue that genotype/phenotype studies involving the Williams syndrome region offer important opportunities to understand the contribution of genes in this region to common disorders affecting the general population.

Duplication of GTF2I results in separation anxiety in mice and humans.

Duplication (dup7q11.23) and deletion (Williams syndrome) of chromosomal region 7q11.23 cause neurodevelopmental disorders with contrasting anxiety phenotypes. We found that 30% of 4- to 12-year-olds with dup7q11.23 but fewer than 5% of children with WS or in the general population met diagnostic criteria for a separation-anxiety disorder. To address the role of one commonly duplicated or deleted gene in separation anxiety, we compared mice that had varying numbers of Gtf2i copies. Relative to mouse pups with one or two Gtf2i copies, pups with additional Gtf2i copies showed significantly increased maternal separation-induced anxiety as measured by ultrasonic vocalizations. This study links the copy number of a single gene from 7q11.23 to separation anxiety in both mice and humans, highlighting the utility of mouse models in dissecting specific gene functions for genomic disorders that span many genes. This study also offers insight into molecular separation-anxiety pathways that might enable the development of targeted therapeutics.

Longitudinal course of anxiety in children and adolescents with Williams syndrome.

The longitudinal course of anxiety disorders in 45 children and adolescents with Williams syndrome (WS) was examined. Children were ages 4-13 years at the initial assessment. To assess their child's DSM-IV diagnoses, parents completed a structured diagnostic interview 3-9 times at intervals of at least 1 year. At the first assessment, 60% of the sample presented with at least one anxiety diagnosis; 82.2% received an anxiety diagnosis at some time during the study. Chronic, persistent anxiety within the period 5 years after their initial diagnosis was shown by 62.2% of those with an anxiety diagnosis (51.1% of the entire sample). The most common diagnoses were specific phobias and generalized anxiety disorder. Multilevel logistic regression models were estimated for the presence of any anxiety disorder, specific phobia, and specific phobia of loud noises. Developmental trajectories, expressed as the probability of a positive diagnosis, suggested that the odds of a positive diagnosis did not change with age. IQ was not significantly related to the presence of an anxiety disorder. However, there was a significant relation between executive functioning and anxiety such that the presence of an anxiety diagnosis was associated with increased scores on behavioral regulation, indicative of increased difficulty with inhibitory control of affect and behavior. These findings are discussed in terms of persistence of anxiety over time and the need to develop and test interventions to address the high levels of anxiety experienced by children and adolescents with WS.
