Quality of life outcomes for people with serious mental illness living in supported accommodation: systematic review and meta-analysis.

PURPOSE: To conduct a systematic review and meta-analysis of quality of life (QoL) outcomes for people with serious mental illness living in three types of supported accommodation. METHODS: Studies were identified that described QoL outcomes for people with serious mental illness living in supported accommodation in six electronic databases. We applied a random-effects model to derive the meta-analytic results. RESULTS: 13 studies from 7 countries were included, with 3276 participants receiving high support (457), supported housing (1576) and floating outreach (1243). QoL outcomes related to wellbeing, living conditions and social functioning were compared between different supported accommodation types. Living condition outcomes were better for people living in supported housing ([Formula: see text]= - 0.31; CI = [- 0.47; - 0.16]) and floating outreach ([Formula: see text]= - 0.95; CI = [- 1.30; - 0.61]) compared to high-support accommodation, with a medium effect size for living condition outcomes between supported housing and floating outreach ([Formula: see text]= - 0.40; CI = [- 0.82; 0.03]), indicating that living conditions are better for people living in floating outreach. Social functioning outcomes were significant for people living in supported housing compared to high support ([Formula: see text] = - 0.37; CI = [- 0.65; - 0.09]), with wellbeing outcomes not significant between the three types of supported accommodation. CONCLUSION: There is evidence that satisfaction with living conditions differs across supported accommodation types. The results suggest there is a need to focus on improving social functioning and wellbeing outcomes for people with serious mental illness across supported accommodation types.

Implementation of a Practice Development Model to Reduce the Wait for Autism Spectrum Diagnosis in Adults.

This study examined waiting times for diagnostic assessment of Autism Spectrum Disorder in 11 adult services, prior to and following the implementation of a 12 month change program. Methods to support change are reported and a multi-level modelling approach determined the effect of the change program on overall wait times. Results were statistically significant (b = - 0.25, t(136) = - 2.88, p = 0.005). The average time individuals waited for diagnosis across all services reduced from 149.4 days prior to the change program and 119.5 days after it, with an average reduction of 29.9 days overall. This innovative intervention provides a promising framework for service improvement to reduce the wait for diagnostic assessment of ASD in adults across the range of spectrum presentations.

Gender ratio in a clinical population sample, age of diagnosis and duration of assessment in children and adults with autism spectrum disorder.

This article reports on gender ratio, age of diagnosis and the duration of assessment procedures in autism spectrum disorder diagnosis in a national study which included all types of clinical services for children and adults. Findings are reported from a retrospective case note analysis undertaken with a representative sample of 150 Scottish children and adults recently diagnosed with autism spectrum disorder. The study reports key findings that the gender ratio in this consecutively referred cohort is lower than anticipated in some age groups and reduces with increasing age. The gender ratio in children, together with the significant difference in the mean age of referral and diagnosis for girls compared to boys, adds evidence of delayed recognition of autism spectrum disorder in younger girls. There was no significant difference in duration of assessment for males and females suggesting that delays in diagnosis of females occur prior to referral for assessment. Implications for practice and research are considered.

Intellectual ability in tuberous sclerosis complex correlates with predicted effects of mutations on TSC1 and TSC2 proteins.

BACKGROUND: Tuberous sclerosis complex is a multisystem genetic disease, caused by mutation in the TSC1 or TSC2 genes, associated with many features, including intellectual disability (ID). We examined psychometric profiles of patients with TSC1 or TSC2 mutations and tested whether different mutation types were associated with different degrees of intellectual ability. METHODS: One hundred subjects with known TSC1/TSC2 mutations were assessed using a range of IQ or developmental quotient (DQ) measures. Effects of mutations on TSC1/TSC2 proteins were inferred from sequence data and published biochemical studies. RESULTS: Most individuals with TSC1 mutations fell on a normal distribution identical to the general population, with ∼10% showing profound ID. Of individuals with TSC2 mutations, 34% showed profound ID, and the remainder a pattern of IQ/DQ more variable and shifted to the left than in TSC1 or the general population. Truncating TSC1 mutations were all predicted to be subject to nonsense-mediated mRNA decay. Mutations predicted to result in unstable protein were associated with less severe effects on IQ/DQ. There was a statistically significant negative correlation between length of predicted aberrant C-terminal tails arising from frameshift mutations in TSC1 and IQ/DQ; for TSC2 a positive but not statistically significant correlation was observed. CONCLUSION: We propose a model where (i) IQ/DQ correlates inversely with predicted levels and/or deleterious biochemical effects of mutant TSC1 or TSC2 protein, and (ii) longer aberrant C-terminal tails arising from frameshift mutations are more detrimental for TSC1 and less for TSC2. Predictions of the model require replication and biochemical testing.

Partial agenesis of the corpus callosum, hippocampal atrophy, and stable intellectual disability associated with Roifman syndrome.

In 2006, we reported the cognitive and behavioral phenotype of the seventh case of Roifman syndrome (OMIM 300258). Aged 11 years 6 months, the patient displayed significant intellectual disability with proportionate impairments in attentional-executive, memory, and visuo-spatial abilities despite appearing socially "able." This discrepancy may be explained by good social-emotional skills masking his intellectual disability, by decline in cognitive abilities over time, or by unusual neuroradiological abnormalities not previously examined in Roifman syndrome. Here, we present results from a structural MRI scan, neurocognitive evaluations repeated 2 and 5 years post-baseline and assessments of face and emotional processing. The MRI revealed partial agenesis of the corpus callosum, bilateral hypoplastic hippocampi but bilaterally intact amygdala. No evidence was found for decline in the patient's neurocognitive profile. Emotional processing data indicated an age-appropriate pattern of reactivity to emotional stimuli and preserved facial identity recognition abilities, but impairments in recognition of negative facial expressions. The results confirmed a stable pattern of intellectual disability, and indicated that Roifman syndrome may be associated with major structural neuro-anatomical abnormalities. We suggest that the relative strengths in emotion and face processing are consistent with the patient's apparently able social behavior, and with intact amygdalar function.

Sirolimus therapy for angiomyolipoma in tuberous sclerosis and sporadic lymphangioleiomyomatosis: a phase 2 trial.

PURPOSE: Renal angiomyolipomas are a frequent manifestation of tuberous sclerosis and sporadic lymphangioleiomyomatosis (LAM). These disorders are associated with mutations of TSC1 or TSC2 that lead to overactivation of mTOR complex 1 (mTORC1), suggesting an opportunity for targeted therapy by using mTORC1 inhibitors. This study investigated the efficacy and safety of the mTORC1 inhibitor sirolimus for treatment of renal angiomyolipomas in patients with these disorders. EXPERIMENTAL DESIGN: In this multicenter phase 2 nonrandomized open label trial, 16 patients with tuberous sclerosis or sporadic LAM and renal angiomyolipoma(s) were treated with oral sirolimus for up to 2 years. Steady-state blood levels were 3 to 10 ng/mL. The primary outcome was change in size of renal angiomyolipomas measured by MRI and assessed by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Secondary outcomes included safety, neurocognitive function, and pulmonary function. RESULTS: The response rate, by RECIST criteria, was 50%. Summated angiomyolipoma diameters were reduced in all 16 patients and by 30% or more in eight (all from the per protocol group of 10). Forty-one of 48 angiomyolipomas were smaller at the last measurement than at baseline. Most shrinkage occurred during the first year of treatment. There was little change in pulmonary function. Recall memory improved in seven of eight patients with tuberous sclerosis. Adverse events were consistent with the known toxicities of sirolimus. CONCLUSIONS: This study showed sustained regression of renal angiomyolipomas in patients with tuberous sclerosis or sporadic LAM receiving 2 years of sirolimus treatment. Possible effects on pulmonary function and neurocognition require further investigation.

Neuropsychological attention skills and related behaviours in adults with tuberous sclerosis complex.

Tuberous sclerosis complex (TSC) is a genetic disorder associated with mTOR over-activation and disruption of MAPK, PI3K and AMPK signalling. Children with TSC have significant deficits on neuropsychological attention tasks, particularly dual tasking. Here we investigated attentional skills and related behaviours in daily life in normally intelligent adults with TSC and matched controls using the Test of Everyday Attention for Children (TEA-Ch) and the Attention-Deficit Scales for Adults (ADSA). No group differences were demonstrated on selective or sustained attention tasks carried out alone. However, adults with TSC performed significantly worse when these tasks were combined in a cross-modal dual task condition. On the ADSA the TSC group had significantly worse scores on several subscales (attention/concentration, behaviour/disorganization, academic and emotional behaviours) compared to controls and these correlated with dual task performance, indicating a clear impact of dual task deficits on attention-related behaviours in daily life. The presence or absence of epilepsy did not influence dual task performance or attention-deficits in daily life. Taken together with similar findings in children, results suggest that dual task difficulties are a core feature of the neuropsychological phenotype of TSC.

Consensus clinical guidelines for the assessment of cognitive and behavioural problems in Tuberous Sclerosis.

Tuberous Sclerosis (TSC) is a genetic disorder characterised by abnormal growths in a wide range of organs. In the brain, abnormalities of differentiation, proliferation and migration can produce a range of neuropsychiatric features such as mental retardation, autism and ADHD. Although these manifestations are not diagnostic of the disorder, cognitive and behavioural features are often of greatest concern to families yet limited clinical assessment and interventions are currently offered. A consensus panel at a TSC Brain/Behaviour workshop recommended that the cognitive and behavioural profiles of individuals with TSC should be assessed at regular intervals in a planned fashion in accordance with the difficulties associated with the disorder. Evaluations should include the use of standardised neuropsychological and behavioural tools as appropriate to the age and developmental level of the individual assessed. These cognitive and behavioural profiles should be incorporated in the overall formulation of the needs of the person with TSC to plan educational, social and clinical management strategies. Assessments should be documented so that individual longitudinal progress can be monitored. The paper outlines the problems associated with TSC, the purpose of recommended assessments, developmentally appropriate stages for assessment, and identifies specific areas that should be targeted for assessment.
