The PRINTO criteria for clinically inactive disease in juvenile dermatomyositis.

OBJECTIVES: To develop data-driven criteria for clinically inactive disease on and off therapy for juvenile dermatomyositis (JDM). METHODS: The Paediatric Rheumatology International Trials Organisation (PRINTO) database contains 275 patients with active JDM evaluated prospectively up to 24 months. Thirty-eight patients off therapy at 24 months were defined as clinically inactive and included in the reference group. These were compared with a random sample of 76 patients who had active disease at study baseline. Individual measures of muscle strength/endurance, muscle enzymes, physician's and parent's global disease activity/damage evaluations, inactive disease criteria derived from the literature and other ad hoc criteria were evaluated for sensitivity, specificity and Cohen's κ agreement. RESULTS: The individual measures that best characterised inactive disease (sensitivity and specificity >0.8 and Cohen's κ >0.8) were manual muscle testing (MMT) ≥78, physician global assessment of muscle activity=0, physician global assessment of overall disease activity (PhyGloVAS) ≤0.2, Childhood Myositis Assessment Scale (CMAS) ≥48, Disease Activity Score ≤3 and Myositis Disease Activity Assessment Visual Analogue Scale ≤0.2. The best combination of variables to classify a patient as being in a state of inactive disease on or off therapy is at least three of four of the following criteria: creatine kinase ≤150, CMAS ≥48, MMT ≥78 and PhyGloVAS ≤0.2. After 24 months, 30/31 patients (96.8%) were inactive off therapy and 69/145 (47.6%) were inactive on therapy. CONCLUSION: PRINTO established data-driven criteria with clearly evidence-based cut-off values to identify JDM patients with clinically inactive disease. These criteria can be used in clinical trials, in research and in clinical practice.

A randomized controlled trial of the effectiveness of a Computer-Assisted Cognitive Remediation (CACR) program in adolescents with psychosis or at high risk of psychosis: Short term and long term outcomes

The present study investigates the short- and long-term outcomes of a computer-assisted cognitive remediation (CACR) program in adolescents with psychosis or at high risk. 32 adolescents participated in a blinded 8-week randomized controlled trial of CACR treatment compared to computer games (CG). Clinical and neuropsychological evaluations were undertaken at baseline, at the end of the program and at 6-month. At the end of the program (n = 28), results indicated that visuospatial abilities (Repeatable Battery for the Assessment of Neuropsychological Status, RBANS; P = .005) improved signifi cantly more in the CACR group compared to the CG group. Furthermore, other cognitive functions (RBANS), psychotic symptoms (Positive and Negative Symptom Scale) and psychosocial functioning (Social and Occupational Functioning Assessment Scale) improved signifi cantly, but at similar rates, in the two groups. At long term (n = 22), cognitive abilities did not demonstrated any amelioration in the control group while, in the CACR group, signifi cant long-term improvements in inhibition (Stroop; P = .040) and reasoning (Block Design Test; P = .005) were observed. In addition, symptom severity (Clinical Global Improvement) decreased signifi cantly in the control group (P = .046) and marginally in the CACR group (P = .088). To sum up, CACR can be successfully administered in this population. CACR proved to be effective over and above CG for the most intensively trained cognitive ability. Finally, on the long-term, enhanced reasoning and inhibition abilities, which are necessary to execute higher-order goals or to adapt behavior to the ever-changing environment, were observed in adolescents benefi ting from a CACR.

Nuestra experiencia clínica en los rescates de PTR con el sistema Legión

We carried out a descriptive, retrospective study with a sample side of 121 patients with Legión® prosthesis replacement in our Vírgen del Rocío hospital area, in the city of Seville, from May of 2008 until March of 2011. This study included epidemiological data as well as technical information about the process performed, including post-operative pain, mobility and functional results using a functional assessment scale and series of radiological studies. Average follow-up was 19 months, with a mean age of 71 years and 87% women. We obtained an average of 20.41º for articular balance obtained, correction of prior deformities by restoring the tibia-femoral axis to the anatomic e balance articular angle; we resolved bone loss prior to replacement and carried out an adequate balance of the inter-lineal joint. 66% of the patients continued with no post-operative pain, with the other 33% reporting slight to moderate pain. With regards to pain at the point of the stem, we have found no significant relationship with the incidence angle of the stem on the cortical or with the type of cement. We observed a 74% rate of intervention without complications, with complications being rupture of the patellar tendon in one patient, one case of peri-prosthesis fracture, two iatrogenic avulsion fractures of the anterior tibial tuberosity and seven infections (4 were diagnosed previously).

Metacognitive training for adolescents with psychosis: A multiple case study

Cognitive biases may be one of the explaining factor underlying psychotic symptoms like delusions and hallucinations. Metacognitive training (MCT) was demonstrated, in adults with schizophrenia, to reduce these cognitive biases. However, to the best of our knowledge, there has been no research on adolescents with psychosis. The current study aimed at assessing the feasibility, treatment adherence and its benefi cial effects on psychotic symptoms, depression, social functioning and self-esteem of a MCT. Participants were fi ve psychotic adolescents with psychosis, aged 16-18, who attended the Day Care Unit for Adolescents (DCUA). The MCT, delivered in group, corresponds to 2x8 modules, lasting between 45 and 60 minutes once a week. To measure MCT's effi ciency, the Positive And Negative Syndrome Scale (PANSS), the Social and Occupational Functioning Assessment Scale (SOFAS), the Health of Nation Outcome Scale for Children and Adolescent (HoNOSCA), the depression scale of Calgary and the self-esteem scale of Rosenberg have been used. The results of the 5 patients indicate that MCT is feasible and the treatment adherence is moderate. The schedule of the MCT needs to be adapted to the availability of the participants. At a descriptive level, the MCT allows to reduce psychotic and depressive symptoms (PANSS & Calgary) as well as to improve the social functioning (SOFAS & HoNOSCA) and self-esteem (Rosenberg). To sum up, MCT seem to be an interesting alternative and/or a good additional treatment to reduce cognitive bias, psychotic symptoms as well as improving social functioning

Predicting clinical scores from magnetic resonance scans in Alzheimer's disease.

Machine learning and pattern recognition methods have been used to diagnose Alzheimer's disease (AD) and mild cognitive impairment (MCI) from individual MRI scans. Another application of such methods is to predict clinical scores from individual scans. Using relevance vector regression (RVR), we predicted individuals' performances on established tests from their MRI T1 weighted image in two independent data sets. From Mayo Clinic, 73 probable AD patients and 91 cognitively normal (CN) controls completed the Mini-Mental State Examination (MMSE), Dementia Rating Scale (DRS), and Auditory Verbal Learning Test (AVLT) within 3months of their scan. Baseline MRI's from the Alzheimer's disease Neuroimaging Initiative (ADNI) comprised the other data set; 113 AD, 351 MCI, and 122 CN subjects completed the MMSE and Alzheimer's Disease Assessment Scale-Cognitive subtest (ADAS-cog) and 39 AD, 92 MCI, and 32 CN ADNI subjects completed MMSE, ADAS-cog, and AVLT. Predicted and actual clinical scores were highly correlated for the MMSE, DRS, and ADAS-cog tests (P<0.0001). Training with one data set and testing with another demonstrated stability between data sets. DRS, MMSE, and ADAS-Cog correlated better than AVLT with whole brain grey matter changes associated with AD. This result underscores their utility for screening and tracking disease. RVR offers a novel way to measure interactions between structural changes and neuropsychological tests beyond that of univariate methods. In clinical practice, we envision using RVR to aid in diagnosis and predict clinical outcome.

Prediction of functional outcome 18 months after a first psychotic episode: a proton magnetic resonance spectroscopy study.

CONTEXT: Recent magnetic resonance imaging studies have attempted to relate volumetric brain measurements in early schizophrenia to clinical and functional outcome some years later. These studies have generally been negative, perhaps because gray and white matter volumes inaccurately assess the underlying dysfunction that might be predictive of outcome. OBJECTIVE: To investigate the predictive value of frontal and temporal spectroscopy measures for outcome in patients with first-episode psychoses. DESIGN: Left prefrontal cortex and left mediotemporal lobe voxels were assessed using proton magnetic resonance spectroscopy to provide the ratio of N-acetylaspartate (NAA) and choline-containing compounds to creatine and phosphocreatine (Cr) (NAA/Cr ratio). These data were used to predict outcome at 18 months after admission, as assessed by a systematic medical record audit. SETTING: Early psychosis clinic. PARTICIPANTS: Forty-six patients with first-episode psychosis. MAIN OUTCOME MEASURES: We used regression models that included age at imaging and duration of untreated psychosis to predict outcome scores on the Global Assessment of Functioning Scale, Clinical Global Impression scales, and Social and Occupational Functional Assessment Scale, as well as the number of admissions during the treatment period. We then further considered the contributions of premorbid function and baseline level of negative symptoms. RESULTS: The only spectroscopic predictor of outcome was the NAA/Cr ratio in the prefrontal cortex. Low scores on this variable were related to poorer outcome on all measures. In addition, the frontal NAA/Cr ratio explained 17% to 30% of the variance in outcome. CONCLUSIONS: Prefrontal neuronal dysfunction is an inconsistent feature of early psychosis; rather, it is an early marker of poor prognosis across the first years of illness. The extent to which this can be used to guide treatment and whether it predicts outcome some years after first presentation are questions for further research.

Personality traits influence clinical outcome in day hospital-treated elderly depressed patients

OBJECTIVES: Although personality traits are considered significant predictors of both physical and mental health, their specific impact on treatment outcome in elderly patients with depression remains largely unexplored. Impact of personality traits on the evolution of depressive symptoms, quality of life, and perception of clinical progress was assessed in a psychotherapeutic community. DESIGN: A prospective longitudinal study was conducted in 62 elderly outpatients. SETTING: Day hospital treatment as usual combined group and individual therapies, pharmacological treatment, as well as family and network meetings. PARTICIPANTS: Patients presented with major depression or a depressive episode of bipolar disease. MEASUREMENTS: The Geriatric Depression Scale, the Short Form Survey, and the Therapeutic Community Assessment scale were administrated at admission, 3, 6, 12 months, and at discharge. Personality was evaluated with the NEO Five-Factor Personality Inventory. RESULTS: Outcome revealed reduced depression and improved mental quality of life and clinical progress. Higher Geriatric Depression Scale scores were found in individuals with higher levels of Neuroticism (and its Vulnerability facet). Better self-perception of clinical progress was observed in individuals with lower levels of the Depressiveness and Modesty facets and higher openness to action. Improvement in quality of life was predicted by high Positive emotions facet. All these associations remained significant after controlling for age, gender, and treatment length. CONCLUSION: Personality traits may predict clinical outcome in psychotherapeutic hospital day care for elderly patients with depression.

Efficacy Of An Explicit Handwriting Program

The aim of this study was to investigate the effects of an explicit handwriting program introduced during the first grade of elementary school. Grade 1 children (N=23) with an age range of 6.1 to 7.4 yr. (15 girls, 8 boys) were administered an additional handwriting program of two weekly sessions of 45 min. over six weeks. Another group of 19 Grade 1 children (11 girls, 8 boys) received only the regular handwriting program of one weekly session. The Concise Assessment Scale for Children's Handwriting was administered to measure the changes in quality and speed of handwriting. The children given the explicit program showed better quality and speed of handwriting than did the control group. Their handwriting was more regular, with fewer ambiguous letters and fewer incorrect relative heights.

Screening for gestational diabetes: variation in guidelines.

OBJECTIVE: To compare published guidelines concerning screening for gestational diabetes. STUDY DESIGN: Systematic search and comparative analysis of published guidelines. Appraisal of guidelines quality. Simulation analysis. RESULTS: Ten published guidelines proposed either universal screening (5), selective screening (3) or screening when clinically indicated (2). Variations of testing schedules and blood glucose thresholds were observed. The quality of the published guidelines was low, on average 22 (8-51) percentage points on the assessment scale. These differences would have led to large variations in the number of patients to be screened. CONCLUSIONS: Large variations between guidelines have been observed which would translate in large practice variations, if the guidelines were systematically applied. These variations are partially explained by the absence of definite evidence that universal or selective screening for gestational diabetes do more good than harm on infant and maternal health. The methodology of developing guidelines should be more evidence based, systematic and explicit.

Rivastigmine for HIV-associated neurocognitive disorders: A randomized crossover pilot study.

OBJECTIVE: To assess the efficacy and safety of rivastigmine for the treatment of HIV-associated neurocognitive disorders (HAND) in a cohort of long-lasting aviremic HIV+ patients. METHODS: Seventeen aviremic HIV+ patients with HAND were enrolled in a randomized, double-blind, placebo-controlled, crossover study to receive either oral rivastigmine (up to 12 mg/day for 20 weeks) followed by placebo (20 weeks) or placebo followed by rivastigmine. Efficacy endpoints were improvement on rivastigmine in the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) and individual neuropsychological scores of information processing speed, attention/working memory, executive functioning, and motor skills. Measures of safety included frequency and nature of adverse events and abnormalities on laboratory tests and on plasma concentrations of antiretroviral drugs. Analyses of variance with repeated measures were computed to look for treatment effects. RESULTS: There was no change on the primary outcome ADAS-Cog on drug. For secondary outcomes, processing speed improved on rivastigmine (Trail Making Test A: F(1,13) = 5.57, p = 0.03). One measure of executive functioning just failed to reach significance (CANTAB Spatial Working Memory [strategy]: F(1,13) = 3.94, p = 0.069). No other change was observed. Adverse events were frequent, but not different from those observed in other populations treated with rivastigmine. No safety issues were recorded. CONCLUSIONS: Rivastigmine in aviremic HIV+ patients with HAND seemed to improve psychomotor speed. A larger trial with the better tolerated transdermal form of rivastigmine is warranted. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that rivastigmine is ineffective for improving ADAS-Cog scores, but is effective in improving some secondary outcome measures in aviremic HIV+ patients with HAND.

Correlation of CXCL10, tumor necrosis factor receptor type II, and galectin 9 with disease activity in juvenile dermatomyositis.

OBJECTIVE: Juvenile dermatomyositis (DM) is a systemic autoimmune disorder of unknown immunopathogenesis in which the immune system targets the microvasculature of skeletal muscles, skin, and other organs. The current mainstay of therapy is a steroid regimen in combination with other immunosuppressive treatments. To date, no validated markers for monitoring disease activity have been identified, which hampers personalized treatment. This study was undertaken to identify a panel of proteins specifically related to active disease in juvenile DM. METHODS: We performed a multiplex immunoassay for plasma levels of 45 proteins related to inflammation in 25 patients with juvenile DM in 4 clinically well-defined groups, as determined by clinical activity and treatment. We compared them to 14 age-matched healthy children and 8 age-matched children with nonautoimmune muscle disease. RESULTS: Cluster analysis of circulating proteins showed distinct profiles for juvenile DM patients and controls based on a group of 10 proteins. In addition to CXCL10, tumor necrosis factor receptor type II (TNFRII) and galectin 9 were significantly increased in active juvenile DM. The levels of these 3 proteins were tightly linked to active disease and correlated with clinical scores (as measured by the Childhood Myositis Assessment Scale and physician's global assessment of disease activity on a visual analog scale). CONCLUSION: Our findings indicate that CXCL10, TNFRII, and galectin 9 correspond to disease status in juvenile DM and thus could be helpful in monitoring disease activity and guiding treatment. Furthermore, they might provide new knowledge about the pathogenesis of this autoimmune disease.

Childhood sexual and physical abuse: age at exposure modulates impact on functional outcome in early psychosis patients.

BACKGROUND: Evidence suggests a relationship between exposure to trauma during childhood and functional impairments in psychotic patients. However, the impact of age at the time of exposure has been understudied in early psychosis (EP) patients. METHOD: Two hundred and twenty-five patients aged 18-35 years were assessed at baseline and after 2, 6, 18, 24, 30 and 36 months of treatment. Patients exposed to sexual and/or physical abuse (SPA) were classified according to age at the time of first exposure (Early SPA: before age 11 years; Late SPA: between ages 12 and 15 years) and then compared to patients who were not exposed to such trauma (Non-SPA). The functional level in the premorbid phase was measured with the Premorbid Adjustment Scale (PAS) and with the Global Assessment of Functioning (GAF) scale and the Social and Occupational Functioning Assessment Scale (SOFAS) during follow-up. RESULTS: There were 24.8% of patients with a documented history of SPA. Late SPA patients were more likely to be female (p = 0.010). Comparison with non-SPA patients revealed that: (1) both Early and Late SPA groups showed poorer premorbid social functioning during early adolescence, and (2) while patients with Early SPA had poorer functional level at follow-up with lower GAF (p = 0.025) and lower SOFAS (p = 0.048) scores, Late SPA patients did not. CONCLUSION: Our results suggest a link between exposure to SPA and the later impairment of social functioning before the onset of the disease. EP patients exposed to SPA before age 12 may present long-lasting functional impairment, while patients exposed at a later age may improve in this regard and have a better functional outcome.

High doses of onabotulinumtoxinA in post-stroke spasticity: a retrospective analysis.

We retrospectively evaluated the efficacy and safety of high doses of onabotulinumtoxinA (from 600 to 800 units) in 26 patients affected by upper and/or lower limb post-stroke spasticity. They were assessed before, 30 and 90 days after treatment. We observed a significant muscle tone reduction and a significant functional improvement (assessed with the Disability Assessment Scale). No adverse events were reported. In our retrospective analysis the treatment with high doses of onabotulinumtoxinA showed to be effective and safe.

Childhood sexual and physical abuse : age at exposure modulates impact on functional outcome in early psychosis patients

Introduction : La littérature suggère un lien entre l'exposition à des expériences traumatiques durant l'enfance et des déficits dans le niveau de fonctionnement chez des patients souffrant de psychose. Par contre, l'impact de l'âge au moment de l'exposition à ces expériences n'a pas été investigué chez des patients dans leur phase précoce de la psychose. Méthodes : Deux cents vingt-cinq patients âgés entre 18 et 35 ans ont été évalués au moment de leur entrée dans un programme thérapeutique spécialisé pour la psychose débutante (TIPP), et après 2, 6, 12, 18, 24, 30 et 36 mois de traitement. Les patients exposés à des abus sexuel et/ou physiques (SPA) ont été classifiés selon l'âge au moment de la première exposition (Early-SPA : avant 11 ans d'âge; Late-SPA : entre 12 et 15 ans d'âge) et ils ont été comparés à des patients qui n'ont jamais été exposés à une telle expérience (Non-SPA). Le niveau de fonctionnement dans la phase premorbide a été mesuré avec la Premorbid Adjustment Scale (PAS) et avec les échelles Global Assessment of Functioning (GAF) et Social and Occupational Functionning Assessment Scale (SOFAS) durant le suivi thérapeutique. Résultats : 24.8 % des patients ont été exposés à SPA. Les patients dans le groupe Late-SPA étaient plus souvent des femmes (p=0.010). Les comparaisons avec les patients dans le groupe Non-SPA ont révélé que : (1) Les patients dans le groupe Early et Late-SPA ont montré un moins bon niveau de fonctionnement social premorbide durant l'adolescence précoce, et (2) alors que les patients dans le groupe Early-SPA ont présenté un moins bon niveau de fonctionnement durant tout le suivi selon les scores de GAF (p=0.025) et SOFAS (p=0.048), les patients dans le groupe Late-SPA n'ont pas montré telles différences avec le groupe non exposé. Conclusion : Nos résultats suggèrent un lien entre l'exposition à SPA et une altération ultérieure de niveau de fonctionnement social, avant l'apparition de la maladie. Les patients dans leur phase précoce de la psychose exposés à SPA avant l'âge de 12 ans ont des altérations fonctionnelles durables, alors que les patients exposés à SPA plus tardivement semblent s'améliorer à ce niveau et montrent une meilleure capacité de récupération.

Patients' Needs for Care in Public Mental Health: Unity and Diversity of Self-Assessed Needs for Care.

PURPOSE: Needs assessment is recognized to be a key element of mental health care. Patients tend to present heterogeneous profiles of needs. However, there is no consensus in previous research about how patients' needs are organized. This study investigates both general and specific dimensions of patients' needs for care. METHODS: Patients' needs were assessed with ELADEB, an 18-domain self-report scale. The use of a self-assessment scale represents a unique way of obtaining patients' perceptions. A patient-centered psychiatric practice facilitates empowerment as it is based on the patients' personal motivations, needs, and wants. Four seventy-one patients' profiles were analyzed through exploratory factor analysis. RESULTS: A four-factor bifactor model, including one general factor and three specific factors of needs, was most adequate. Specific factors were (a) "finances" and "administrative tasks"; (b) "transports," "public places," "self-care," "housework," and "food"; and (c) "family," "children," "intimate relationships," and "friendship." CONCLUSION: As revealed by the general factor, patients expressing urgent needs in some domains are also more susceptible to report urgent needs in several other domains. This general factor relates to high versus low utilizers of public mental healthcare. Patients also present specific needs in life domains, which are organized in three dimensions: management, functional disabilities, and familial and interpersonal relationships. These dimensions relate to the different types of existing social support described in the literature.
