  1. Adult attachment and psychosocial functioning

    OpenAIRE

    Pielage, Suzanne Brenda

    2006-01-01

    In the trilogy Attachment, Separation and Loss (1969, 1973, 1980), Bowlby theorized that early experiences with caregivers affect the quality of individuals’ later (romantic) relationships and, consequently, their mental health. The current thesis set out to examine the relationships between adult attachment and psychosocial functioning, predominately in the realm of close relationships. In the first part of the thesis, the focus lay on the assessment of the adult attachment construct. In Cha...

    2011-02-01

    Data from neurobiologic and psychosocial outcomes research suggest that, phenomenologically, clinically, and neurobiologically, patients with schizoaffective disorder occupy an intermediate position between more severely disturbed schizophrenia patients and similarly or less severely impaired affective disorder patients. Some biologic-genetic abnormalities are shared between these disorders, while other abnormalities are specific to particular symptoms. Premorbid functioning, especially in academic areas, is better in patients with schizoaffective disorder than in those with schizophrenia, but negative symptoms and cognitive deficits are influential and should be addressed to improve psychosocial outcomes.

    Scoring functions are a class of computational methods widely applied in structure-based drug design for evaluating protein-ligand interactions. Dozens of scoring functions have been published since the early 1990s. In literature, scoring functions are typically classified as force-field-based, empirical, and knowledge-based. This classification scheme has been quoted for more than a decade and is still repeatedly quoted by some recent publications. Unfortunately, it does not reflect the recent progress in this field. Besides, the naming convention used for describing different types of scoring functions has been somewhat jumbled in literature, which could be confusing for newcomers to this field. Here, we express our viewpoint on an up-to-date classification scheme and appropriate naming convention for current scoring functions. We propose that they can be classified into physics-based methods, empirical scoring functions, knowledge-based potentials, and descriptor-based scoring functions. We also outline the major difference and connections between different categories of scoring functions.

  6. Functional dyspepsia: Are psychosocial factors of relevance?

    The pathogenesis of Functional Dyspepsia (FD) remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease.Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation.Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant.The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intrinsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management.Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to variation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.

    The association between global functionality and religiosity among patients from developing and predominantly Catholic countries warrants attention. To compare religiosity and psychosocial functioning in Mexican schizophrenia patients with and without a history of religious delusions, seventy-four patients with paranoid schizophrenia were recruited. Patients with a history of religious delusions had more psychiatric hospitalizations and poorer psychosocial functioning compared with those without a history of religious delusions. No differences emerged between groups in the total scores of religiosity scales. A history of religious delusions rather than religiosity itself may have an influence on psychosocial functioning among Mexican patients with schizophrenia.

    During the last 25 years Denmark has regularly contributed to international missions through the deployment of Danish soldiers. From 1992 till 2014 32,000 Danish women and men have been deployed. With this mapping of publications we aim to contribute with an overview of publications within...... the research field of psychosocial functioning and health among relatives living with a veteran, including potential gaps within this research field. We have found 103 publications. Most of them are American, 7 are from Europe and none from Scandinavia. Most publications focus on the partner’s relationship...... to the veteran or the mental health of the partner while relatively few publications deal with the veteran family as a whole or its members social relations outside the primary family. Furthermore, there are relatively few publications focusing on relatives to veterans deployed other places than Iraq...

    2006-02-01

    Researchers have highlighted the significance of a poor body image in the development of dysfunctional eating but have systematically investigated few other outcomes. The authors examined the relationships between different aspects of body image and psychosocial functioning. Participants were 245 boys and 173 girls from Grades 8 and 9 (M age = 13.92 years, SD = 0.69 years). Respondents completed measures of physical attractiveness, body satisfaction, body image importance, body image behaviors, appearance comparison, social physique anxiety, self-esteem, depression, anxiety, and same-sex and opposite-sex relations. Whereas girls tended to report a more negative body image than did boys, the relevance of body image to self-esteem was similar for boys and girls. Concern about others' evaluation of their bodies was especially important in understanding low female self-esteem, whereas for boys, ratings of general attractiveness most strongly predicted self-esteem. The authors found a negative body image to be unrelated to symptoms of negative affect but to be strongly associated with poor opposite-sex peer relationships, especially among boys. A negative body image also affected same-sex relations among girls.

    Both medical and psychological factors have an important impact upon the psychosocial functioning of young people with epilepsy. The purpose of this study was to identify factors that distinguish young people with epilepsy and high psychosocial functioning from those with lower levels. The participants were 114 young people (40 males, 74 females) with active epilepsy and a mean age of 17.92years (SD=3.90) who completed either a paper (60.5%) or a web-based survey (39.5%) comprising demographic, medical, and psychosocial measures. Psychosocial measures included family functioning, adolescent coping, anxiety, depression, and quality of life. A latent class analysis produced two psychosocial functioning groups based on participants' scores for anxiety, depression, and quality of life. Young people were more likely to be members of the group with poor psychosocial functioning if they had a seizure in the last month (Wald=5.63, p<.05), came from families with lower levels of communication and problem solving (Wald=5.28, p<.05), and made greater use of non-productive (emotion-focused) coping strategies such as wishful thinking, withdrawal, and worry (Wald=12.00, p<.01). The findings suggest that, in addition to standard medical treatment, clinicians may promote better outcomes by strengthening family functioning and encouraging less use of nonproductive coping strategies.

    Full Text Available Abstract Background Psychosocial functioning is poor in patients with pectus excavatum (PE. However, a comprehensive understanding of this issue does not exist. The aim of this study was to assess the severity of psychosocial problems as associated with PE, as well as to identify its risk factors. Methods A comparative study was performed at the Sichuan Academy of Medical Sciences/Sichuan Provincial People's Hospital in Chengdu, China. Patients age 6 to 16 who admitted to the outpatient department for the evaluation or treatment for PE were included in the study. In addition to parental reports of child psychosocial problems on the Achenbach Child Behavior Checklist (CBCL, parents also filled in other structured questionnaires, including socio-demographic variables, patients' medical and psychological characteristics. The severity of malformation was assessed by CT scan. For comparison, an age- and gender- matched control group was recruited from the general population. The socio-demographic and scores on CBCL were compared between patients and control subjects. Univariate and multivariate analysis were performed to examine risk factors for psychosocial problems in patients. Results No statistically significant differences were found with respect to social-demographic variables between children with PE and control subjects. Compared with control subjects, children with PE displayed higher prevalence of psychosocial problems in the different scales of the CBCL questionnaire such as 'withdraw', 'anxious-depressed', 'social problems' and 'total problems'. Both univariate and multivariate analyses suggested that age, severity of malformation, and being teased about PE were significantly associated with patients' psychosocial problems. Conclusions The information derived from this study supports the opinion that children with PE have more psychosocial problems than children from the general population. Multiple medical and psychosocial factors were

    This study was conducted as a two-group pretest-posttest design to determine the effect of psychosocial skills training on functional remission levels of patients with schizophrenia. A total of 100 patients were divided into the training group (n = 50) and the control group (n = 50). The data were collected using a Personal Information Form and Functional Remission of General Schizophrenia (FROGS) scale. The 13-session training program was given in the form of face-to-face group training and 45- to 60-min sessions twice a week. Training was completed by five groups. Every group comprised of 9 to 12 individuals on average. The training group had higher scores significantly on functional remission levels compared with the control group after psychosocial skills training (p Psychosocial skills training has become considerably effective in increasing the functional remission levels of patients with schizophrenia.

    2015-01-01

    Automated docking allows rapid screening of protein-ligand interactions. A scoring function composed of a force field and linear weights can be used to compute a binding energy from a docked atom configuration. For different force fields or types of molecules, it may be necessary to train a custom scoring function. This chapter describes the data and methods one must consider in developing a custom scoring function for use with AutoDock.

  14. Functional impairment, stress, and psychosocial intervention in bipolar disorder.

    2011-12-01

    The longitudinal course of bipolar disorder (BD) is highly impairing. This article reviews recent research on functional impairment in the course of BD, the roles of social and intrafamilial stress in relapse and recovery, and the role of adjunctive psychosocial interventions in reducing risk and enhancing functioning. Comparative findings in adult and childhood BD are highlighted. Life events and family-expressed emotion have emerged as significant predictors of the course of BD. Studies of social information processing suggest that impairments in the recognition of facial emotions may characterize both adult- and early-onset bipolar patients. Newly developed psychosocial interventions, particularly those that focus on family and social relationships, are associated with more rapid recovery from episodes and better psychosocial functioning. Family-based psychoeducational approaches are promising as early interventions for children with BD or children at risk of developing the disorder. For adults, interpersonal therapy, mindfulness-based strategies, and cognitive remediation may offer promise in enhancing functioning.

    A study included 100 patients (47 men and 53 women) with cerebral stroke. We revealed significant disordres of cognitive and psychosocial functions (memory, social integration and decision making) in the early stage of rehabilitation. The Functional Independence Measure (FIM) score at baseline (beginning of the early stage of rehabilitation) was 17.3 +/- 7.7. There was a partial recovery of cognitive and psychosocial functions during the rehabilitation that reflected in increasing of FIM score to 25.9 +/- 7.0. Neglect syndrome and severity of lesion (hemiplegia) had a significant negative effect on the effectiveness of occupational therapy (p occupational therapy significantly improves the independence of patients.

    This study examines psychosocial functioning in children with neurodevelopmental disorders (NDDs) and/or externalizing behavior problems (EBPs) as compared to children with neither condition. The longitudinal sample, drawn from the Canadian National Longitudinal Survey of Children and Youth, included children who were 6 to 9 years old in Cycle 1 who were followed-up biennially in Cycles 2 and 3 (N = 3476). The associations between NDDs and/or EBPs, child and family socio-demographic characteristics and parenting behaviors (consistency and ineffective parenting), were examined across several measures of child psychosocial functioning: peer relationships, general self-esteem, prosocial behavior and anxiety-emotional problems. Children with NDDs, EBPs, and both NDDs and EBPs self-reported lower scores on general self-esteem. Children with NDDs and both NDDs and EBPs reported lower scores on peer relationships and prosocial behavior. Lastly, children with both NDDs and EBPs self-reported higher scores on anxiety-emotional behaviors. After considering family socio-demographic characteristics and parenting behaviors, these differences remained statistically significant only for children with both NDDs and EBPs. Child age and gender, household income and parenting behaviors were important in explaining these associations. Psychosocial functioning differs for children with NDDs and/or EBPs. Children with both NDDs and EBPs appear to report poorer psychosocial functioning compared to their peers with neither condition. However, it is important to consider the context of socio-demographic characteristics, parenting behaviors and their interactions to understand differences in children's psychosocial functioning. Implication for Rehabilitation: Practitioners may wish to consider complexity in child health by examining a comprehensive set of determinants of psychosocial outcomes as well as comorbid conditions, such as neurodevelopmental disorders (NDDs) and externalizing

    The authors sought to explore how conduct, hyperactivity/inattention, and emotional symptoms are associated with neural reactivity to social-emotional stimuli, and the extent to which psychosocial stress modulates these relationships. Participants were community adolescents recruited as part of the European IMAGEN study. Bilateral amygdala regions of interest were used to assess the relationship between the three symptom domains and functional MRI neural reactivity during passive viewing of dynamic angry and neutral facial expressions. Exploratory functional connectivity and whole brain multiple regression approaches were used to analyze how the symptoms and psychosocial stress relate to other brain regions. In response to the social-emotional stimuli, adolescents with high levels of conduct or hyperactivity/inattention symptoms who had also experienced a greater number of stressful life events showed hyperactivity of the amygdala and several regions across the brain. This effect was not observed with emotional symptoms. A cluster in the midcingulate was found to be common to both conduct problems and hyperactivity symptoms. Exploratory functional connectivity analyses suggested that amygdala-precuneus connectivity is associated with hyperactivity/inattention symptoms. The results link hyperactive amygdala responses and regions critical for top-down emotional processing with high levels of psychosocial stress in individuals with greater conduct and hyperactivity/inattention symptoms. This work highlights the importance of studying how psychosocial stress affects functional brain responses to social-emotional stimuli, particularly in adolescents with externalizing symptoms.

    Full Text Available Introduction. Major depressive disorder (MDD and bipolar affective disorder (BAD are among the leading causes of disability. These are often associated with widespread impairments in all domains of functioning including relational, occupational, and social. The main aim of the study was to examine and compare nature and extent of psychosocial impairment of patients with MDD and BAD during depressive phase. Methodology. 96 patients (48 in MDD group and 48 in BAD group were included in the study. Patients were recruited in depressive phase (moderate to severe depression. Patients having age outside 18–45 years, psychotic symptoms, mental retardation, and current comorbid medical or axis-1 psychiatric disorder were excluded. Psychosocial functioning was assessed using Range of Impaired Functioning Tool (LIFE-RIFT. Results. Domains of work, interpersonal relationship, life satisfaction, and recreation were all affected in both groups, but the groups showed significant difference in global psychosocial functioning score only (P=0.031 with BAD group showing more severe impairment. Conclusion. Bipolar depression causes higher global psychosocial impairment than unipolar depression.

    Endoscopic thoracic sympathectomy is considered the treatment modality of choice for patients with disabling hyperhidrosis. However, the psychosocial impact of the intervention has not been systematically studied in American samples before and after sympathectomy. It is expected that the reduction of symptoms is associated with improved psychosocial functioning and quality of life. The aim of this study was to examine psychosocial functioning in patients with hyperhidrosis undergoing thoracic sympathectomy. Patients with hyperhidrosis undergoing evaluation for sympathectomy were recruited from Shands Hospital at the University of Florida. Fifty-one patients completed individual psychological assessment batteries prior to undergoing sympathectomy and at 1-month follow-up, measuring the constructs of health-related quality of life, anxiety, and depression. Repeated-measures analyses of variance revealed that 1 month after sympathectomy, patients reported significant improvements across the domains of physical quality of life (p=0.01), mental quality of life (p=0.005), trait anxiety (pSympathectomy resulted in increases in health-related quality of life, and decreases in anxiety and depression within 1 month post procedure. Results suggest that sympathectomy exists as an effective treatment choice for both medical and psychosocial outcomes in patients with hyperhidrosis.

    In this study, we report on the changes in psychosocial functioning over 1 year following breast cancer surgery in 3 groups of women, including those with mastectomy alone, those with mastectomy and immediate reconstruction, and those with delayed reconstruction. Women with breast cancer at 2 teaching hospitals in Ontario who were undergoing mastectomy alone, mastectomy with immediate reconstruction, or delayed reconstruction were asked to complete a battery of psychosocial questionnaires at their preoperative appointment and 1 year following surgery. A total of 190 women consented to participate in the study and completed the presurgical questionnaires. There were no presurgical differences between the 3 groups in quality of life, anxiety, depression, or sexual functioning. However, women who were undergoing delayed breast reconstruction (i.e., already had a mastectomy) had higher levels of body stigma (P = 0.01), body concerns (P = 0.002), and transparency (P = 0.002) than women who were undergoing mastectomy alone or mastectomy with immediate reconstruction. Of these women, 158 (83.2%) completed the 1-year follow-up. There were no significant differences in any of the psychosocial functioning scores between the 3 groups. Contrary to the assumed psychological benefits of breast reconstruction, psychological distress was evident among women regardless of reconstruction or timing of reconstruction. Further, psychosocial functioning (including quality of life, sexual functioning, cancer-related distress, body image, depression, and anxiety) was not different at 1-year postsurgery between women with mastectomy alone, mastectomy with immediate reconstruction, and delayed reconstruction. These results suggest that women need psychosocial support after breast cancer diagnosis, even if they have breast reconstruction.

    This study explored the impact of hair pulling on psychosocial functioning for patients diagnosed with trichotillomania (TTM; n = 28). TTM patients were compared to age and gender-matched groups of psychiatric patients without TTM (n = 28) and nonpsychiatric control volunteers (NC, n = 28) on measures of psychological distress, functioning/quality of life, and self-esteem. Results indicated that TTM patients reported more severe psychosocial impairments than did NC volunteers; however, these differences were mediated by differences in level of depression. Regression analyses indicated significant relationships between some measures of psychosocial functioning and severity of hair pulling, independent of level of depression. Finally, an interview of the impact of hair pulling on 6 domains of daily functioning (negative affect/negative self-evaluations, grooming, recreational activities, social interaction, work/housework productivity, and physical health) indicated common and wide-ranging impairments for both lifetime and current (i.e., past week) ratings. These results highlight the importance of promoting and improving resources for the clinical care of TTM patients, and provide some directions for clinicians to enhance assessment of interference caused by TTM.

    2010-01-01

    Psychobiologic evidence and psychosocial functioning in patients with schizoaffective disorder suggest that the disease may be a distinct disorder, a variant of schizophrenia or affective disorders, the comorbidity of schizophrenia and a mood disorder, or an intermediate disorder on a spectrum that ranges from schizophrenia to mood disorders. These data, although inconclusive, contribute to clinicians' understanding of the etiology of the disorder. Further research may lead to an increased understanding of the disorder, improved treatment, and, ultimately, better outcomes.

    Full Text Available Abstract Background Although patients with Treatment Resistant Depression (TRD often have impaired social functioning, few studies have investigated the effectiveness of psychosocial treatment for these patients. We examined whether adding group cognitive behavioral therapy (group-CBT to medication would improve both the depressive symptoms and the social functioning of patient with mild TRD, and whether any improvements would be maintained over one year. Methods Forty-three patients with TRD were treated with 12 weekly sessions of group-CBT. Patients were assessed with the Global Assessment of Functioning scale (GAF, the 36-item Short-Form Health Survey (SF-36, the Hamilton Rating Scale for Depression (HRSD, the Dysfunctional Attitudes Scale (DAS, and the Automatic Thought Questionnaire-Revised (ATQ-R at baseline, at the termination of treatment, and at the 12-month follow-up. Results Thirty-eight patients completed treatment; five dropped out. For the patients who completed treatment, post-treatment scores on the GAF and SF-36 were significantly higher than baseline scores. Scores on the HRSD, DAS, and ATQ-R were significantly lower after the treatment. Thus patients improved on all measurements of psychosocial functioning and mood symptoms. Twenty patients participated in the 12-month follow-up. Their improvements for psychosocial functioning, depressive symptoms, and dysfunctional cognitions were sustained at 12 months following the completion of group-CBT. Conclusions These findings suggest a positive effect that the addition of cognitive behavioural group therapy to medication on depressive symptoms and social functioning of mildly depressed patients, showing treatment resistance.

    Depression, alexithymia, and lack of assertiveness interfere with individual psychosocial functioning and may result in longer hospitalization stay and poorer therapeutic results. To analyze the psychosocial functioning in acute and chronic patients and its association with psychological, clinical and sociodemographic variables. We performed a cross-sectional study that included 80 inpatients of both sexes with organic pathology, aged between 18 to 70 years old, without any current psychiatric disorder. Clinical and sociodemographic data were collected from a semi-structured interview and hospital records. Beck Depression Inventory-IA, Toronto Alexithymia Scale-20 and Rathus Assertiveness Scale were administered. Fifty five percent of patients had some degree of depression, 33% alexithymia and 34% lack of assertiveness. The levels of depression, alexithymia and lack of assertiveness in chronic patients were significantly higher than those observed in acute patients. Women and participants older than 60 years exhibited the highest degrees of depression. Alexithymia and lack of assertiveness were associated with a lower educational level. A negative significant correlation between alexithymia and assertiveness scores was observed among acute patients. Participants with chronic diseases had a lower psychosocial functioning. Less educated patients showed more alexithymic and less assertive features. We emphasized the need of a better management of these aspects by the health team, since social functioning might interfere with the outcome of physical illnesses.

    The diagnosis, treatment, and side effects of childhood cancer have been described as extremely stressful experiences in the life of a child. Anecdotally, children report that a sense of humor helps them cope with the daily experiences of living with cancer; however, no research has examined sense of humor and childhood cancer stressors. This study investigated the effect of sense of humor on the relationship between cancer stressors and children's psychosocial adjustment to cancer, immune function, and infection using Lazarus and Folkman's theory of stress, appraisal, and coping. A direct relationship was observed between sense of humor and psychosocial adjustment to cancer, such that children with a high sense of humor had greater psychological adjustment, regardless of the amount of cancer stressors. A moderating effect was observed for incidence of infection. As childhood cancer stressors increase, children with high coping humor scores reported fewer incidences of infection than low scorers.

    The present study investigated the relationship between psychological symptoms and psychosocial function and the role of relevant sociodemographic data and antipsychotic use in the prediction of psychosocial function among multiracial schizophrenia outpatients in Malaysia. A total of 223 participants were recruited in this cross-sectional study conducted from December 2010 to April 2011. Psychological symptoms were assessed using the Positive and Negative Syndrome Scale whilst the psychosocial function was assessed using the Personal and Social Performance scale. Sociodemographic and treatment variables were gathered through interview or review of the medical records. All dimensions of psychosocial functions were inversely correlated with Positive and Negative Syndrome Scale sub-domains. Only the disorganization sub-domain significantly predicts all dimensions of psychosocial function. For social data, body mass index and employment status were significant predictors of all dimensions of psychosocial functions. Typical antipsychotics significantly predict social function negatively as compared to sulpiride (β = -0.152, P = 0.028). We found that the relationship between psychological symptoms and psychosocial functions were relatively consistent with the findings from the Caucasian population. Additionally, disorganization was the only significant predictor of all dimensions of psychosocial functions. This further emphasized the importance of cognition in psychosocial function. The roles of sulpiride, body mass index and employment status as predictors of psychosocial function were also discussed. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

    Full Text Available OBJECTIVE: To examine psychosocial functioning in eating disorder (ED patients with restrictive and purgative subtypes. METHOD: Forty-four adult female patients with a diagnosis of ED were divided into restrictive (RP and purgative (PP groups according the presence of purgative symptoms. Functioning was assessed using the Functioning Assessment Short Test (FAST and the Global Assessment of Functioning Scale (GAF. RESULTS: No differences were found in total FAST scores or in specific domains between the RP (39.58±11.92 and PP (45.75±11.75 groups (p = 0.19. However, PP showed more severe functional impairment than RP in the financial domain (p < 0.01. There were no differences in comorbidity with mood disorders, depressive symptoms, or general psychiatric symptoms between the two ED subtypes. CONCLUSIONS: The similarities found between PP and PR in overall functioning and in autonomy, cognition, work, interpersonal relationships, and leisure seem to reflect the use of an objective scale that corresponds to the clinical impression. In fact, the assessment of psychosocial functioning in ED patients using self-report instruments requires careful consideration because results may reflect the egosyntonic nature of symptoms commonly observed in these patients, particularly in the restrictive subtype.

    To examine the psychosocial functioning of adults with congenital craniofacial conditions relative to normative data. Single sample cross-sectional design. The Australian Craniofacial Unit, Women's and Children's Hospital, Adelaide, which is one of the main craniofacial treatment centers in Australia. Adults (N  =  93) with congenital craniofacial conditions (excluding cleft lip/palate) who were treated in the Australian Craniofacial Unit. All participants completed self-report scales assessing health-related quality of life (SF-36); life satisfaction, anxiety, and depression (HADS); self-esteem (Rosenberg); appearance-related concerns; perceived social support; and social anxiety. Overall, participants were very similar in psychosocial function to the general population. However, adults with craniofacial conditions were less likely to be married and have children (females), were more likely to be receiving a disability pension, and reported more appearance-related concerns and less social support from friends. They also reported more limitations in both their social activities, due to physical or emotional problems, and usual role activities, because of emotional problems, as well as poorer mental health. These results give cause to be very positive about the long-term outcomes of children who are undergoing treatment for craniofacial conditions, while also identifying specific areas that interventions could target.

    A questionnaire survey of 363 children and young adults with juvenile arthritis was conducted to assess the relations among disease severity, psychosocial functioning, and adjustment in three age groups--primary school, high school, and young adult. Parents were surveyed separately to determine which characteristics of the ill child at different ages most significantly impact the well-being of the family. Indices of psychologic functioning and disease severity were associated with adjustment in the primary school and high school groups, whereas measures of social relationships were strongly associated with adjustment only in the high school group. Relations among measures of psychologic functioning, social relationships, disease severity, and adjustment in young adults were minimal. Level of disease severity was associated with the presence of financial concerns, emotional problems, and physical strain in parents of high school children and young adults. The results emphasize the importance of using a developmental model for understanding the adjustment of individuals with chronic juvenile arthritis and their families.

    Full Text Available Abstract Background Mutagenesis is commonly used to engineer proteins with desirable properties not present in the wild type (WT protein, such as increased or decreased stability, reactivity, or solubility. Experimentalists often have to choose a small subset of mutations from a large number of candidates to obtain the desired change, and computational techniques are invaluable to make the choices. While several such methods have been proposed to predict stability and reactivity mutagenesis, solubility has not received much attention. Results We use concepts from computational geometry to define a three body scoring function that predicts the change in protein solubility due to mutations. The scoring function captures both sequence and structure information. By exploring the literature, we have assembled a substantial database of 137 single- and multiple-point solubility mutations. Our database is the largest such collection with structural information known so far. We optimize the scoring function using linear programming (LP methods to derive its weights based on training. Starting with default values of 1, we find weights in the range [0,2] so that predictions of increase or decrease in solubility are optimized. We compare the LP method to the standard machine learning techniques of support vector machines (SVM and the Lasso. Using statistics for leave-one-out (LOO, 10-fold, and 3-fold cross validations (CV for training and prediction, we demonstrate that the LP method performs the best overall. For the LOOCV, the LP method has an overall accuracy of 81%.

    Full Text Available Previous studies have established that scores on Major Depressive Disorder scales are correlated with measures of impairment of psychosocial functioning. It remains unclear, however, whether individual depressive symptoms vary in their effect on impairment, and if so, what the magnitude of these differences might be. We analyzed data from 3,703 depressed outpatients in the first treatment stage of the Sequenced Treatment Alternatives to Relieve Depression (STAR*D study. Participants reported on the severity of 14 depressive symptoms, and stated to what degree their depression impaired psychosocial functioning (in general, and in the five domains work, home management, social activities, private activities, and close relationships. We tested whether symptoms differed in their associations with impairment, estimated unique shared variances of each symptom with impairment to assess the degree of difference, and examined whether symptoms had variable impacts across impairment domains. Our results show that symptoms varied substantially in their associations with impairment, and contributed to the total explained variance in a range from 0.7% (hypersomnia to 20.9% (sad mood. Furthermore, symptoms had significantly different impacts on the five impairment domains. Overall, sad mood and concentration problems had the highest unique associations with impairment and were among the most debilitating symptoms in all five domains. Our findings are in line with a growing chorus of voices suggesting that symptom sum-scores obfuscate relevant differences between depressed patients and that substantial rewards will come from close attention to individual depression symptoms.

    Full Text Available Objective: To assess cognitive performance and psychosocial functioning in patients with bipolar disorder (BD, in unaffected siblings, and in healthy controls. Methods: Subjects were patients with BD (n=36, unaffected siblings (n=35, and healthy controls (n=44. Psychosocial functioning was accessed using the Functioning Assessment Short Test (FAST. A sub-group of patients with BD (n=21, unaffected siblings (n=14, and healthy controls (n=22 also underwent a battery of neuropsychological tests: California Verbal Learning Test (CVLT, Stroop Color and Word Test, and Wisconsin Card Sorting Test (WCST. Clinical and sociodemographic characteristics were analyzed using one-way analysis of variance or the chi-square test; multivariate analysis of covariance was used to examine differences in neuropsychological variables. Results: Patients with BD showed higher FAST total scores (23.90±11.35 than healthy controls (5.86±5.47; p < 0.001 and siblings (12.60±11.83; p 0.001. Siblings and healthy controls also showed statistically significant differences in FAST total scores (p = 0.008. Patients performed worse than healthy controls on all CVLT sub-tests (p < 0.030 and in the number of correctly completed categories on WCST (p = 0.030. Siblings did not differ from healthy controls in cognitive tests. Conclusion: Unaffected siblings of patients with BD may show poorer functional performance compared to healthy controls. FAST scores may contribute to the development of markers of vulnerability and endophenotypic traits in at-risk populations.

    Used standardized questionnaires to compare psychosocial functioning of 116 children and adolescents (9 to 18 years) and 73 adults (18 to 38 years) operated on for hypospadias, a congenital penile anomaly, with that of 88 and 50 age-matched comparison males, respectively, treated for an inguinal hernia. The relationships of coping with penile appearance, subject age, severity of hypospadias, number of operations, age at final surgery, and type of surgical procedure with psychosocial functioning were also investigated. Hypospadias patients did not exhibit a poorer psychosocial functioning and no significant relationships of various medical characteristics with psychosocial functioning could be discerned. Genital/body perception of hypospadias patients ages 9 to 18 years correlated positively with psychosocial functioning, albeit with low values. These findings are important for psychologists and specialists in the counseling process of hypospadias patients and their parents.

Neuropsychological function of both groups was also compared with normative scores from control samples.The childhood-onset group displayed deficits in verbal learning and memory, higher rates of psychosis, childhood maltreatment and more serious violent behavior, all effects associated with a large effect size. Both groups had impaired executive function, falling within the extremely low range (severely impaired.Childhood-onset CD displayed greater cognitive impairment, more psychiatric symptoms and committed more serious violent offences. The finding of severe executive impairment in both childhood- and adolescent-onset groupings challenges the assumption that adolescent-onset antisocial behavior is a normative process.

    Decrements in one or more domains of psychosocial functioning (e.g., poor job performance, poor interpersonal relations) are commonly observed in psychiatric patients. The purpose of this study is to increase understanding of psychosocial functioning as a broad, multifaceted construct as well as its associations with both adaptive- and maladaptive-range personality traits in both nonclinical and psychiatric outpatient samples. The study was conducted in two phases. In Study 1, a nonclinical sample (N = 429) was administered seven psychosocial functioning and adaptive-range personality trait measures. In Study 2, psychiatric outpatients (N = 181) were administered the same psychosocial functioning measures, and maladaptive- as well as adaptive-range personality trait measures. Exploratory (both studies) and confirmatory (Study 2) factor analyses indicated a common three-factor, hierarchical structure of psychosocial functioning-Well Being, Social/Interpersonal Functioning, and Basic Functioning. These psychosocial functioning domains were closely--and differentially--linked with personality traits, especially strongly so in patients. Across samples, Well Being was associated with both Neuroticism/Negative Affectivity and Extraversion/Positive Affectivity, Social/Interpersonal Functioning was associated with both Agreeableness and Conscientiousness/Disinhibition, and Basic Functioning was associated with Conscientiousness/Disinhibition, although only modestly in the nonclinical sample. These relations generally were maintained even after partialing out current general dysphoric symptoms. These findings have implications for considering psychosocial functioning as an important third domain in a tripartite model together with personality and psychopathology.

    2008-01-01

    Full Text Available Orthognathic surgery is a well-accepted treatment for patients with skeletal discrepancies. The primary motivation of many patients who seek orthognathic surgery is esthetics and not for correction of functional disability. The treatment is incomplete if the surgeon attempts to correct the physical deformity alone without adequate understanding and regard for the emotional framework. The purpose of this study is aimed at patient′s self-perceptions of facial form oral function and psychosocial function before and after orthognathic surgery. Fifty patients were included in the study, of which 21 were used as control. Twenty-two questions were asked to evaluate the problem in all four areas as mentioned earlier. Each question takes a score from one to five. In group I, the internal consistency of each scale indicates moderate to high internal reliability, ranging from α = 0.71 for general health to α = 0.88 for psychosocial problem. In group II, except for functional problems, the internal consistency of each scale has moderate to high reliability. The psychological wellbeing of an orthognathic surgery patient is enhanced by careful preoperative counseling regarding the expected surgical treatment objectives, the operative course, and the expected postoperative sequelae. Patients who undergo orthognathic surgery readily accept the changes in their postoperative appearance and are satisfied with achieved results.

    OBJECTIVE This study assessed the impact of a psychosocial skills training program, consisting of psychoeducation, interpersonal group therapy and family education incorporated into social skills training, as an integrative approach on social functioning and quality of life of patients with schizophrenia, in comparison to standard care for an 8-month period. METHOD Thirty patients with DSM-IV schizophrenia were included in the study. Patients were assessed using the Positive and Negative Syndrome Scale (PANSS), Quality of Life Scale (QLS), Social Functioning Scale (SFS), and Global Assessment of Function (GAF) at baseline. Fifteen patients underwent an 8-month psychosocial skills training group program and another fifteen patients (waiting list) continued in standard care. Both groups were reassessed and analyzed at the end of the study. RESULTS Two groups were not statistically different in terms of total PANSS, QLS, SFS, GAF scores, and demographic characteristics at baseline. However, there was a significant improvement in the mean total QLS, SFS, GAF, and even in total PANSS scores (respectively from 64.46±19.58 to 89.67±24.10, Ppsychosocial skills training program for patients with schizophrenia. It can be concluded that this comprehensive psychosocial skills training program might be an important contribution to the functioning of the patients.

    Psychosocial factors have been found to have a significant impact on functional activity, particularly among persons with chronic pain. While various systems have been developed to assess functional limitations through functional capacity evaluation (FCE), assessment of psychosocial factors that may impact function have been largely ignored. This paper examines the existing literature on psychosocial factors and FCE performance. Given that there are few studies that have directly addressed this issue, the paper also examines psychosocial factors that have been found to influence function in persons with pain. The results of the literature review indicate that few psychosocial factors have been found to be directly associated with FCE and functional measures, although many are related to various measures of disability. The strongest evidence that psychosocial factors are related to functional performance is based on the studies examining the association between functional activity and pain-related fear, self-efficacy, and illness behavior. Psychosocial factors have also been shown to influence measures of sincerity of effort often obtained during FCE. Proposals for modifying FCE assessment are given based on the available data, as well as suggestions for future research.

    Protein-ligand docking is a useful tool for providing atomic-level understanding of protein functions in nature and design principles for artificial ligands or proteins with desired properties. The ability to identify the true binding pose of a ligand to a target protein among numerous possible candidate poses is an essential requirement for successful protein-ligand docking. Many previously developed docking scoring functions were trained to reproduce experimental binding affinities and were also used for scoring binding poses. However, in this study, we developed a new docking scoring function, called GalaxyDock BP2 Score, by directly training the scoring power of binding poses. This function is a hybrid of physics-based, empirical, and knowledge-based score terms that are balanced to strengthen the advantages of each component. The performance of the new scoring function exhibits significant improvement over existing scoring functions in decoy pose discrimination tests. In addition, when the score is used with the GalaxyDock2 protein-ligand docking program, it outperformed other state-of-the-art docking programs in docking tests on the Astex diverse set, the Cross2009 benchmark set, and the Astex non-native set. GalaxyDock BP2 Score and GalaxyDock2 with this score are freely available at http://galaxy.seoklab.org/softwares/galaxydock.html.

  3. The psychosocial function of reincarnation among Druze in Israel.

    2006-03-01

    To gain an understanding of the psychosocial function of reincarnation among Druze, interviews were conducted with nine male subjects who had experienced reincarnation (Notq) and with one or two of their family members. Analysis of these interviews revealed that the onset of Notq typically occurs at between two and five years of age. Five of the subjects had displayed psychological distress in their childhood that was alleviated after the Notq. Once the child has displayed initial indications of reincarnation, such as mentioning names that the family construes as being from a past life, the family takes an active role in constructing the past-life story and matching it to a known real story involving a tragic death. This match creates a new order in the life of the child, the family, and the past-life family. All parties benefit from this new order: the child receives new special attention and love and becomes able to control and manipulate the parents; the parents are relieved because they see the child happy, and benefit from the social attention and regard they receive; and the grieving of the bereaved past-life family is alleviated by the realization that the soul of their lost son still lives. The findings support the sociocognitive notion of the constructing of past memories by the social environment. Additional research that should include data collection from the past-life family and examination of the affinity of reincarnation with dissociation and child abuse is recommended.

    Full Text Available Autodock Vina is a very popular, and highly cited, open source docking program. Here we present a scoring function which we call Vinardo (Vina RaDii Optimized. Vinardo is based on Vina, and was trained through a novel approach, on state of the art datasets. We show that the traditional approach to train empirical scoring functions, using linear regression to optimize the correlation of predicted and experimental binding affinities, does not result in a function with optimal docking capabilities. On the other hand, a combination of scoring, minimization, and re-docking on carefully curated training datasets allowed us to develop a simplified scoring function with optimum docking performance. This article provides an overview of the development of the Vinardo scoring function, highlights its differences with Vina, and compares the performance of the two scoring functions in scoring, docking and virtual screening applications.

    Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) has a major impact on a woman's psychological and sexual well-being. In most of the studies that addressed treatment techniques, postoperative sexual function was reported to be satisfactory; however, comparatively few studies have additionally provided an accurate analysis of psychosocial functions in MRKHS patients following different kinds of neovaginal treatment. This study is to evaluate sexual and psychosocial functioning after creation of a neovagina according to Wharton-Sheares-George in women with MRKHS. We performed a case-control-study using multiple measures to assess sexual and psychosocial functioning. Ten MRKHS patients and 20 controls of a University hospital and tertiary center for pediatric and adolescent gynecology were assessed. The follow-up assessment comprised 6 standardized questionnaires (Female Sexuality Function Index, FSFI; Patient Health Questionnaire, PHQ; Brief Symptom Inventory, BSI; World Health Organization Quality of Life Assessment, WHOQoL-BREF; Parental Bonding Instrument, PBI; and a German questionnaire on body image). The main outcome measures were sexual function, psychological status, quality of life, body image, and parental bonding styles. Sexual function, psychological status (including depressive and somatic symptoms), quality of life, and own-body experience were at least as good in operated MRKHS patients as in controls. In some measures (FSFI, PHQ-15, psychological domain of the WHOQoL-BREF, and BSI Positive Symptom Total), patients scored significantly better than controls. The results of the PBI indicated a close and sustainable mother-daughter-relationship in MRKHS patients. We found no evidence for an impairment of sexual or psychosocial functioning in patients after neovaginoplasty according to Wharton-Sheares-George. MRKHS may not necessarily compromise sexual and psychological well-being, provided that the syndrome is properly managed by a multidisciplinary team

Methods. Cross-sectional survey. Demographics, medical data, Locomotor Capabilities Index (LCI, and Discomfort-Engagement in Everyday Activities Involving Revealing the Body Scale (D-EEARB were collected from thirty-two adults who suffered from LLA in childhood or LLD. Results. Most of the sample (53.1% males was working (84.4%, living independently (75%, and single (75%. Mean age was 33.16 (SD = 7.64, range 18–50. Leading causes for LLA were traumatic (40.6% and oncologic (25%. LLD was present in 6 cases (18.8%. LCI scores revealed a high performance among males (t17,464=2.976, p=.008. D-EEARB scores showed that 56.25% stated feeling “quite” or “totally comfortable” in situations which involved revealing their body, but 43.75% stated the contrary (“uncomfortable” or “very uncomfortable”. LLD and traumatic LLA show higher scores in D-EEARB than vascular and oncological LLA (χ2=7.744, df = 3, p=.05. Conclusions. Adults suffering from LLDs and LLAs during childhood seem to perform well once they are adults. However, 43.75% of patients express considerable discomfort in situations that involve revealing the body.

For the clinical oncologist, it is important to be aware that sexual problems or sexual dysfunction may occur as a result of any aspect of cancer and cancer treatment. Sexual function is sensitive to the effects of trauma, both physical and emotional. This is particularly the case for patients whose cancer affects their genitals. Despite some commonalities of psychosocial and psychosexual issues in GU patients across diagnostic categories, GU patients do not present as one distinct, homogeneous group. GU neoplasms, with the exception of bladder cancer, affect mostly men. Men and women tend to differ in their ways of dealing with emotional distress and physical illness. While the man may typically do well using denial as a defense and may not want to discuss his feelings about his diagnosis and treatment, his partner may suffer if her way of coping is oriented toward communicating thoughts and feelings about the situation. Another important difference in this population is related to age and developmental differences. Testicular cancer typically is diagnosed in young men between the ages of 15 and 34 (46). The patients often still live with their parents or have just formed families of their own. In contrast, prostate cancer is diagnosed in older men, who are at a completely different stage in their lives when they have to deal with this challenge. Developmental stage at the time of diagnosis and treatment is an important variable in adaptation to cancer (47). Since GU malignancies and their treatments directly or indirectly affect sexual organs and sexual functioning, issues of sexual body image and identity as men or women are frequent concerns for GU patients. This is most obviously the case for men facing penectomy or orchiectomy. Similarly, women undergoing cystectomy with its simultaneous removal of uterus, ovaries, and parts of the vaginal wall face

    Full Text Available Abstract Background Development of effective scoring functions is a critical component to the success of protein structure modeling. Previously, many efforts have been dedicated to the development of scoring functions. Despite these efforts, development of an effective scoring function that can achieve both good accuracy and fast speed still presents a grand challenge. Results Based on a coarse-grained representation of a protein structure by using only four main-chain atoms: N, Cα, C and O, we develop a knowledge-based scoring function, called NCACO-score, that integrates different structural information to rapidly model protein structure from sequence. In testing on the Decoys'R'Us sets, we found that NCACO-score can effectively recognize native conformers from their decoys. Furthermore, we demonstrate that NCACO-score can effectively guide fragment assembly for protein structure prediction, which has achieved a good performance in building the structure models for hard targets from CASP8 in terms of both accuracy and speed. Conclusions Although NCACO-score is developed based on a coarse-grained model, it is able to discriminate native conformers from decoy conformers with high accuracy. NCACO is a very effective scoring function for structure modeling.

    Full Text Available This study investigated the effects of early institutional care on memory and executive functioning. Subjects were participants in the Bucharest Early Intervention Project (BEIP and included institutionalized children, children with a history of institutionalization who were assigned to a foster care intervention, and community children in Bucharest, Romania. Memory and executive functioning were assessed at the age of eight years using the Cambridge Neuropsychological Test and Automated Battery (CANTAB. As expected, children with a history of early institutional care performed worse on measures of both visual memory and executive functioning compared to their peers without a history of institutional care. In comparing children randomly assigned to the foster care intervention with their peers who had continued care in the institution, initial comparisons did not show significant differences on any of the memory or executive functioning outcomes. However, for one of the measures of executive functioning, after controlling for birth weight, head circumference, and duration of time spent in early institutional care, the foster care intervention was a significant predictor of scores. These results support and extend previous findings of deficits in memory and executive functioning among school-age children with a history of early deprivation due to institutional care. This study has implications for the millions of children who continue to experience the psychosocial deprivation associated with early institutional care.

    BACKGROUND: Assessment of psychosocial functioning in people with schizophrenia is important. The Global Assessment of Functioning (GAF-F) scale represents a widely applied, easy, and quick tool, but its validity and reliability have been debated. The aim was to investigate whether GAF-F scores...... are associated with other indicators of functioning, severity, and hospitalization. METHODS: A Danish population-based cohort study of adults (≥18 years) with a recorded GAF-F score at first-time schizophrenia diagnosis during 2004-2011 was performed. The internal validity of GAF-F was evaluated by assessing its...... association with other baseline measures of functioning and illness severity. Risk of schizophrenia hospitalization within 2 years was evaluated using Cox regression stratified by sex and adjusted for age, year of diagnosis, and inpatient/outpatient status at diagnosis. RESULTS: We identified 2,837 cases...

    This study aimed to examine clinical validity and utility of a screening measure for familial psychosocial risk, the Psychosocial Assessment Tool 2.0 (PAT2.0), among pediatric cancer survivors participating in long-term survivorship care. Caregivers (N=79) completed the PAT2.0 during their child's survivorship appointment. Caregivers also reported on family engagement in outpatient mental health treatment. Medical records were reviewed for treatment history and oncology provider initiated psychology consults. The internal consistency of the PAT2.0 total score in this survivorship sample was strong. Psychology was consulted by the oncology provider to see 53% of participant families, and families seen by psychology had significantly higher PAT2.0 total scores than families without psychology consults. PAT2.0 total scores and corresponding subscales were higher for patients, parents, and siblings enrolled in outpatient mental health services since treatment completion. Results were consistent with psychosocial risk categories presented within the Pediatric Psychosocial Preventative Health Model. Fifty-one percent of families presenting for survivorship care scored in the "universal" category, 34% scored in the "targeted" category, and 15% scored in the "clinical" category. Data indicate that the overall proportions of families experiencing "universal", "targeted", and "clinical" levels of familial distress may be constant from the time of diagnosis into survivorship care. Overall, the PAT2.0 demonstrated strong psychometric properties among survivors of pediatric cancer and shows promise as a psychosocial screening measure to facilitate more effective family support in survivorship care.

    We aimed to compare the degree of symptom relief to psychosocial functional (abbreviated as "functional") improvement and explore the relationships between symptom relief and functional improvement during acute electroconvulsive therapy for patients with major depressive disorder. Major depressive disorder inpatients (n=130) requiring electroconvulsive therapy were recruited. Electroconvulsive therapy was generally performed for a maximum of 12 treatments. Symptom severity, using the 17-item Hamilton Depression Rating Scale, and psychosocial functioning (abbreviated as "functioning"), using the Modified Work and Social Adjustment Scale, were assessed before electroconvulsive therapy, after every 3 electroconvulsive therapy treatments, and after the final electroconvulsive therapy. Both 17-item Hamilton Depression Rating Scale and Modified Work and Social Adjustment Scale scores were converted to T-score units to compare the degrees of changes between depressive symptoms and functioning after electroconvulsive therapy. Structural equation modeling was used to test the relationships between 17-item Hamilton Depression Rating Scale and Modified Work and Social Adjustment Scale during acute electroconvulsive therapy. One hundred sixteen patients who completed at least the first 3 electroconvulsive therapy treatments entered the analysis. Reduction of 17-item Hamilton Depression Rating Scale T-scores was significantly greater than that of Modified Work and Social Adjustment Scale T-scores at assessments 2, 3, 4, and 5. The model analyzed by structural equation modeling satisfied all indices of goodness-of-fit (chi-square = 32.882, P =.107, TLI = 0.92, CFI = 0.984, RMSEA = 0.057). The 17-item Hamilton Depression Rating Scale change did not predict subsequent Modified Work and Social Adjustment Scale change. Functioning improved less than depressive symptoms during acute electroconvulsive therapy. Symptom reduction did not predict subsequent functional improvement

    Theme: Parenting/parenthood. The diagnosis of complex CHD impacts the psychosocial status of parents and their functioning. A critical evaluation of the literature concerning the psychosocial parental response to their infant's diagnosis of complex CHD. Systematic review of 18 articles published after 2000 in PubMed and CINAHL. The impact of an infant's CHD on the family functioning is determined both by child's medical condition and family's psychosocial factors. The majority of parents experience intense loss and numerous stressors. Nurses and physicians need to be sensitive to the needs, thoughts and experiences of the parents when discussing treatment options. Families with poor social support networks may have the greatest need for professional interventions. Appropriate interventions assist the majority of parents to adapt to the diagnosis of complex CHD. However, there are a number of parents with an increased psychosocial risk associated with higher rates of emotional distress.

    This study was conducted to establish (a) the stability of the DSM-5 Section III personality disorder (PD) traits, (b) whether these traits predict future psychosocial functioning, and (c) whether changes in traits track with changes in psychosocial functioning across time. Ninety-three outpatients (61% female) diagnosed with at least 1 PD completed patient-report measures at 2 time-points (M time between assessments = 1.44 years), including the Personality Inventory for the DSM-5 and several measures of psychosocial functioning. Effect sizes of rank-order and mean-level change were calculated. In addition, Time 1 traits were used to predict functioning measures at Time 2. Finally, latent change score models were estimated for DSM-5 Section III traits and functioning measures, and correlations among latent change scores were calculated to establish the relationship between change in traits and functional outcomes. Findings demonstrated that the DSM-5 Section III traits were highly stable in terms of normative (i.e., mean-level) change and rank-order stability over the course of the study. Furthermore, traits prospectively predicted psychosocial functioning. However, at the individual level traits and functioning were not entirely static over the study, and change in individuals' functioning tracked with changes in trait levels. These findings demonstrate that the DSM-5 Section III traits are highly stable consistent with the definition of PD, prospectively predictive of psychosocial functioning, and are dynamically associated with functioning over time. This study provides important evidence in support of the DSM-5 Section III PD model.

    Research examining psychosocial functioning in African American prostate cancer survivors has been limited, in spite of documented higher mortality from prostate cancer and worse long-term physical and emotional outcomes from prostate cancer treatment reported by this group of survivors. In addition, the role of masculinity in psychosocial adjustment among prostate cancer survivors is not well understood. In this study, 59 African American prostate cancer survivors completed a questionnaire assessing masculinity beliefs related to self-reliance, emotional control, and dominance, as well as measures of psychosocial functioning (i.e., symptom distress, negative mood, and functional and social well-being). Results of regression analyses indicated that masculinity beliefs predicted negative mood, functional well-being, and social well-being, controlling for age, income, and medical comorbidities. The findings reported here, although preliminary, suggest that masculinity beliefs could be important therapeutic targets for improving the efficacy of cognitive-behavioral interventions for men adjusting to prostate cancer survivorship.

    Full Text Available Objective: This study aimed to evaluate the relationship between oxidative stress markers and cognitive functions and domains of psychosocial functioning in bipolar disorder. Methods: Oxidative stress markers, cognitive functions, and domains of psychosocial functioning were evaluated in 51 patients with bipolar disorder who were in remission. Correlation analyses between these parameters were calculated with data controlled for duration of illness and number of episodes. Results: There was no statistically significant correlation between oxidative stress markers and cognitive functions. In terms of psychosocial functioning, significant correlations were found between malondialdehyde and sense of stigmatization (r = -0.502; household activities and superoxide dismutase (r = 0.501; participation in social activities and nitric oxide (r = 0.414; hobbies and leisure time activities and total glutathione (r = -0.567, superoxide dismutase (r = 0.667, and neurotrophin 4 (r = 0.450; and taking initiative and self-sufficiency and superoxide dismutase (r = 0.597. There was no correlation between other domains of psychosocial functioning and oxidative stress markers. Conclusion: These results imply that oxidative stress markers do not appear to correlate clearly with cognitive impairment and reduced psychosocial functioning. However, there were some associations between selected oxidative markers and activity-oriented functional markers. This may represent a true negative association, or may be an artifact of oxidative stress being a state rather than a trait marker.

    Protein-RNA docking is still an open question. One of the main challenges is to develop an effective scoring function that can discriminate near-native structures from the incorrect ones. To solve the problem, we have constructed a knowledge-based residue-nucleotide pairwise potential with secondary structure information considered for nonribosomal protein-RNA docking. Here we developed a weighted combined scoring function RpveScore that consists of the pairwise potential and six physics-based energy terms. The weights were optimized using the multiple linear regression method by fitting the scoring function to L_rmsd for the bound docking decoys from Benchmark II. The scoring functions were tested on 35 unbound docking cases. The results show that the scoring function RpveScore including all terms performs best. Also RpveScore was compared with the statistical mechanics-based method derived potential ITScore-PR, and the united atom-based statistical potentials QUASI-RNP and DARS-RNP. The success rate of RpveScore is 71.6% for the top 1000 structures and the number of cases where a near-native structure is ranked in top 30 is 25 out of 35 cases. For 32 systems (91.4%), RpveScore can find the binding mode in top 5 that has no lower than 50% native interface residues on protein and nucleotides on RNA. Additionally, it was found that the long-range electrostatic attractive energy plays an important role in distinguishing near-native structures from the incorrect ones. This work can be helpful for the development of protein-RNA docking methods and for the understanding of protein-RNA interactions.

We investigated (a whether socioeconomic status moderates the relationship between parenting and child psychosocial outcomes, (b whether parenting mediates the relation between socioeconomic status and psychosocial functioning in a Peruvian context and finally, (c whether there are interaction effects between positive parenting and negative behavioral control. Information was gathered on 591 Peruvian children and their families from the normal population in urban zones of Metropolitan Lima. Hierarchical multiple regression analyses were conducted to investigate direct and indirect effects (mediation and moderation. Results revealed a significant mediation effect of positive parenting and negative behavioral control in the relationship between socioeconomic status and self-worth. Implications about the role played by context are discussed.

    Full Text Available Background: Strabismus adversely affects psychosocial and functional aspects; while its correction impacts positively. Aim: The aim was to evaluate the gains in scores: Overall scores (OASs, psychosocial subscale scores (PSSs and functional subscale scores (FSSs following successful surgical alignment. Settings and Design: We evaluated changed scores in the adult strabismus 20 (AS-20 questionnaire, administered before and after successful surgery. Materials and Methods: Thirty adults horizontal strabismics, were administered the AS-20, at baseline, and at 6-week and 3-month. Group-wise analysis was carried out based on gender, strabismus type (esotropia [ET] or exotropia [XT], back-ground and amblyopia. Statistical Analysis: We used Wilcoxon, and Mann-Whitney U-tests. Significance was set at P ≤ 0.05. Results: At baseline, there were no significant differences within the groups, except that those with amblyopia significantly scored less than nonamblyopes in OAS (median scores: 53.8 vs. 71.3; P = 0.009 and FSS (56.3 vs. 85.3; P = 0.009. OAS, PSS and FSS showed significant gains at 6-week and 3-month (all Wilcoxon P < 0.001. Compared with males, females showed significantly more gain at 3-month (OAS: 37.9 vs. 28.7; P = 0.02, on account of PSS gain (49.6 vs. 37.5; P = 0.01. The ET performed better than XT only on the FSS at 6-week (28.7 vs. 15.0; P = 0.02. Vis-à-vis the nonamblyopes, the amblyopes showed significantly more benefit at 6-week alone (OAS: 18.7 vs. 28.7; P = 0.04, largely due to gains in PSS. Conclusions: Successful strabismus surgery has demonstrated significant gains in psychosocial, functional and overall functions. There is some evidence that gains may be more in females; with a trend to better outcomes in ET and amblyopes up to 6-week.

    For women who have mastectomy, breast reconstruction is an option which may improve psychosocial functioning. The purpose of this study was to evaluate changes in psychosocial functioning over a long follow-up period after mastectomy, specifically examining the differences between those with mastectomy alone and those who underwent postmastectomy delayed breast reconstruction (DBR). This was a prospective longitudinal survey study of women with mastectomy in which a repeated measures design was used to compare psychosocial function scores over 3 timepoints: 1) pre-mastectomy; 2) one year post-mastectomy; and 3) long-term post-mastectomy (mean 6.3 years). In addition, psychosocial functioning was compared between the mastectomy alone group and the group who elected for DBR. 67 women who completed questionnaires at all three time points were included. The long-term follow-up time post-mastectomy was 75.2 months (6.3 years). Twenty-eight women (41.8%) underwent DBR in the study period. For the entire cohort, between one-year and long-term post-mastectomy, there were significant improvements in scores for body concerns (P = 0.03), cancer-related distress (P = 0.01), and total distress (P = 0.04). At long-term follow-up, women with DBR had significantly higher levels of total distress (P = 0.01), obsessiveness (P = 0.03), and cancer-related distress (P = 0.02) compared to those with mastectomy alone. There were no differences in quality of life between the two groups at any time point. Psychosocial functioning improves over time in patients treated with mastectomy in the long-term breast cancer survivorship period, which may be related to the effect of time post-treatment, rather than an effect of choice for or against DBR. © 2014 Wiley Periodicals, Inc.

    Background Severe stress experienced in early life may have long-term effects on adult physiological and psychological health and well-being. We studied physical and psychosocial functioning in late adulthood in subjects separated temporarily from their parents in childhood during World War II. Methods The 1803 participants belong to the Helsinki Birth Cohort Study, born 1934–44. Of them, 267 (14.8%) had been evacuated abroad in childhood during WWII and the remaining subjects served as controls. Physical and psychosocial functioning was assessed with the Short Form 36 scale (SF-36) between 2001 and 2004. A test for trends was based on linear regression. All analyses were adjusted for age at clinical examination, social class in childhood and adulthood, smoking, alcohol intake, physical activity, body mass index, cardiovascular disease and diabetes. Results Physical functioning in late adulthood was lower among the separated men compared to non-separated men (b = −0.40, 95% confidence interval [95% CI]: −0.71 to −0.08). Those men separated in school age (>7 years) and who were separated for a duration over 2 years had the highest risk for lower physical functioning (b = −0.89, 95% CI: −1.58 to −0.20) and (b = −0.65, 95% CI: −1.25 to −0.05), respectively). Men separated for a duration over 2 years also had lower psychosocial functioning (b = −0.70, 95% CI: −1.35 to −0.06). These differences in physical and psychosocial functioning were not observed among women. Conclusion Early life stress may increase the risk for impaired physical functioning in late adulthood among men. Timing and duration of the separation influenced the physical and psychosocial functioning in late adulthood. PMID:23861956

    To assess the validity of the original low-risk SCORE function without and with high-density lipoprotein cholesterol and SCORE calibrated to the Spanish population. Pooled analysis with individual data from 12 Spanish population-based cohort studies. We included 30 919 individuals aged 40 to 64 years with no history of cardiovascular disease at baseline, who were followed up for 10 years for the causes of death included in the SCORE project. The validity of the risk functions was analyzed with the area under the ROC curve (discrimination) and the Hosmer-Lemeshow test (calibration), respectively. Follow-up comprised 286 105 persons/y. Ten-year cardiovascular mortality was 0.6%. The ratio between estimated/observed cases ranged from 9.1, 6.5, and 9.1 in men and 3.3, 1.3, and 1.9 in women with original low-risk SCORE risk function without and with high-density lipoprotein cholesterol and calibrated SCORE, respectively; differences were statistically significant with the Hosmer-Lemeshow test between predicted and observed mortality with SCORE (P < .001 in both sexes and with all functions). The area under the ROC curve with the original SCORE was 0.68 in men and 0.69 in women. All versions of the SCORE functions available in Spain significantly overestimate the cardiovascular mortality observed in the Spanish population. Despite the acceptable discrimination capacity, prediction of the number of fatal cardiovascular events (calibration) was significantly inaccurate. Copyright © 2017 Sociedad Española de Cardiología.

    Molecular docking simulations are of pivotal importance for analysis of protein-ligand interactions and also an essential resource for virtual-screening initiatives. In molecular docking simulations several possible docked structures are generated, which create an ensemble of structures representing binary complexes. Therefore, it is crucial to find the best solution for the simulation. One approach to this problem is to employ empirical scoring function to identify the best docked structure. It is expected that scoring functions show a descriptive funnel-shaped energy surface without many false minima to impair the efficiency of conformational sampling. We employed this methodology against a test set with 300 docked structures. Docking simulations of these ligands against enzyme binding pocket indicated a funnel-shaped behavior of the complexation for this system. This review compares a set of recently proposed polynomial empirical scoring functions, implemented in a program called POLSCORE, with two popular scoring function programs (XSCORE and DrugScore). Overall comparison indicated that POLSCORE works better to predict the correct docked position, for the ensemble of docked structures analyzed in the present work.

    Full Text Available Abstract Background Schizophrenia is among the most disabling of mental illnesses and frequently causes impaired functioning. We explore issues of definition and terminology, and the relationship between social functioning, cognition, and psychopathology considering relevant research findings. Methods The present article describes measures of social functioning and outlines their psychometric properties. It considers their usefulness in research and clinical settings. Treatment aims and objectives are explored in the context of cognitive and social functioning. Finally, we identify areas for developing research and refining the measurement of social functioning. Results The definition and measurement of social functioning in schizophrenia remains a complex and disputed area. The relationships between symptoms, cognitive functioning and social functioning are complex but we are beginning to understand them better. Scales for measuring functioning in clinical practice must be brief and sensitive to change and the Personal and Social Performance (PSP scale may offer several advantages in these regards. Brief cognitive assessments focusing upon the domains most commonly affected in schizophrenia, such as verbal memory and executive functions, should be coadministered with measures of functioning. Conclusions The use of validated scales for schizophrenia that are sensitive to change over the course of the illness and its treatment, should allow for a better understanding of patients' functional disabilities, enabling better and more comprehensive monitoring and evaluation of both pharmacological and non-pharmacological treatment strategies.

    Psychosocial function and adherence to antiretroviral regimen are key factors in human immunodeficiency virus (HIV) disease management. Alexithymia (AL) is a trait deficit in the ability to identify and describe feelings, emotions and bodily sensations. A structural equation model was used to test whether high levels of AL indirectly relate to greater non-adherent behavior and HIV disease severity via psychosocial dysfunction. Blood draws for HIV-1 viral load and CD4 T-lymphocyte, along with psychosocial surveys were collected from 439 HIV positive adults aged 18-73 years. The structural model supports significant paths from: (1) AL to non-active patient involvement, psychological distress, and lower social support, (2) psychological distress and non-active involvement to non-adherent behavior, and (3) non-adherence to greater HIV disease severity (CFI = .97, RMSEA = .04, SRMR = .05). A second model confirmed the intermediary effect of greater patient assertiveness on the path from AL to social support and non-active patient involvement (CFI = .94, RMSEA = .04, SRMR = .05). Altogether, AL is indirectly linked with HIV disease management through it's association with poor psychosocial function, however greater patient assertiveness buffers the negative impact of AL on relationship quality with healthcare providers and members of one's social support network.

    Chronic depression is associated with impaired functioning. The National Epidemiologic Survey of Alcoholism and Related Conditions (NESARC) is a representative sample (N=43,093) of the United States non-institutionalized population aged 18years and older. We hypothesized that individuals with chronic low-grade depression, dysthymic disorder, would have more impaired functioning than individuals with acute major depression or the general population. Diagnoses were generated by the NIAAA Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version (AUDADIS-IV). The dysthymic disorder (DD) sample (N=328) consisted of DD diagnosis without current MDD. The dysthymic group was not chosen on the basis of alcohol use or abuse. Individuals with MDD with duration ≦24months, without lifetime DD constituted the acute depression (AD) sample (N=712). All other respondents were classified as general population (GP) (N=42,052). Past year functioning was assessed by Supplemental Social Security Income (SSI), employment, and Medicaid statuses. Past month functioning was assessed by Short-form 12-Item Health Survey (SF-12), with scores for social functioning, role emotional functioning, and mental health, using odds ratios. Over the past year, compared to AD, persons with DD were less likely to work full-time (36.2% vs. 44%; OR=0.70, CI=.54,.92) and more often received SSI (13.9% vs. 4.5%; OR=3.4, CI=2.0,5.9) and Medicaid (20.2% vs. 13%; OR=1.7 , CI=1.1,2.6). Dysthymics reported accomplishing less over the past month due to emotional problems, and that emotional or physical problems interfered with social activities. Relative to GP, respondents with DD were more likely to receive SSI (13.9% vs. 2.9%; OR=4.6, CI 3.4,6.2) and Medicaid (20.2% vs. 5.9%; OR=2.9, CI 2.0,4.1). Compared to GP, dysthymics reported accomplishing less due to emotional problems, and that emotional or physical problems interfered with social activities and work functioning. DD

    The purpose of this study was to determine the mean values of the functional movement screen (FMS) in a group of long-distance runners. The secondary aims were to investigate whether the FMS performance differed between sexes and between young and older runners. Forty-three runners, 16 women (mean age = 33.5 years, height = 165.2 cm, weight = 56.3 kg, and body mass index [BMI] = 20.6) and 27 men (mean age = 39.3 years, height = 177.6 cm, weight = 75.8 kg, and BMI = 24.2) performed the FMS. All the runners were injury-free and ran >30 km·wk. Independent t-tests were performed on the composite scores to examine the differences between men and women and also between young (40 years). Contingency tables (2 × 2) were developed for each of the 7 screening tests to further look at the differences in groups for each single test. The χ values were calculated to determine significant differences. Statistical significance was set at p ≤ 0.05. There was no significant difference in the composite score between women and men. There were significant differences between the sexes in the push-up and straight leg test scores, with the women scoring better on each test. A significant difference was found in the composite scores between younger and older runners (p score differences were found for the squat, hurdle step, and in-line lunge tests with the younger runners scoring better. This study provided mean values for the FMS in a cohort of long-distance runners. These values can be used as a reference for comparing FMST scores in other runners who are screened with this tool.

    Full Text Available Early psychosocial deprivation can negatively impact the development of executive functions (EF. Here we explore the impact of early psychosocial deprivation on behavioral and physiological measures (i.e. event-related potentials; ERPs of two facets of EF, inhibitory control and response monitoring, and their associations with internalizing and externalizing outcomes in the Bucharest Early Intervention Project (BEIP; Zeanah et al., 2003. This project focuses on two groups of children placed in institutions shortly after birth and then randomly assigned in infancy to either a foster care intervention or to remain in their current institutional setting. A group of community controls was recruited for comparison. The current study assesses these children at 8-years of age examining the effects of early adversity, the potential effects of the intervention on EF and the role of EF skills in socio-emotional outcomes. Results reveal exposure to early psychosocial deprivation was associated with impaired inhibitory control on a flanker task. Children in the foster care intervention exhibited stronger response monitoring compared to children who remained in the institution on the error-related positivity (Pe. Moreover, among children in the foster care intervention those who exhibited stronger error-related negativity (ERN responses had lower levels of socio-emotional behavior problems. Overall, these data identify specific aspects of EF that contribute to adaptive and maladaptive socio-emotional outcomes among children experiencing early psychosocial deprivation.

    The objective of this study was to establish latent executive function (EF) and psychosocial adjustment factor structure, to examine associations between EF and psychosocial adjustment, and to explore potential development differences in EF-psychosocial adjustment associations in healthy children and adolescents. Using data from the multisite National Institutes of Health (NIH) magnetic resonance imaging (MRI) Study of Normal Brain Development, the current investigation examined latent associations between theoretically and empirically derived EF factors and emotional and behavioral adjustment measures in a large, nationally representative sample of children and adolescents (7-18 years old; N = 352). Confirmatory factor analysis (CFA) was the primary method of data analysis. CFA results revealed that, in the whole sample, the proposed five-factor model (Working Memory, Shifting, Verbal Fluency, Externalizing, and Internalizing) provided a close fit to the data, χ(2)(66) = 114.48, p psychosocial adjustment associations. Findings indicate that childhood EF skills are best conceptualized as a constellation of interconnected yet distinguishable cognitive self-regulatory skills. Individual differences in certain domains of EF track meaningfully and in expected directions with emotional and behavioral adjustment indices. Externalizing behaviors, in particular, are associated with latent Working Memory and Verbal Fluency factors.

  3. Empirical evaluation of scoring functions for Bayesian network model selection.

    In this work, we empirically evaluate the capability of various scoring functions of Bayesian networks for recovering true underlying structures. Similar investigations have been carried out before, but they typically relied on approximate learning algorithms to learn the network structures. The suboptimal structures found by the approximation methods have unknown quality and may affect the reliability of their conclusions. Our study uses an optimal algorithm to learn Bayesian network structures from datasets generated from a set of gold standard Bayesian networks. Because all optimal algorithms always learn equivalent networks, this ensures that only the choice of scoring function affects the learned networks. Another shortcoming of the previous studies stems from their use of random synthetic networks as test cases. There is no guarantee that these networks reflect real-world data. We use real-world data to generate our gold-standard structures, so our experimental design more closely approximates real-world situations. A major finding of our study suggests that, in contrast to results reported by several prior works, the Minimum Description Length (MDL) (or equivalently, Bayesian information criterion (BIC)) consistently outperforms other scoring functions such as Akaike's information criterion (AIC), Bayesian Dirichlet equivalence score (BDeu), and factorized normalized maximum likelihood (fNML) in recovering the underlying Bayesian network structures. We believe this finding is a result of using both datasets generated from real-world applications rather than from random processes used in previous studies and learning algorithms to select high-scoring structures rather than selecting random models. Other findings of our study support existing work, e.g., large sample sizes result in learning structures closer to the true underlying structure; the BDeu score is sensitive to the parameter settings; and the fNML performs pretty well on small datasets. We also

    Objective The purpose of this study was to examine the connections between family dynamics and the psychosocial functioning of children with spinal cord injuries and disorders (SCI/D). Design Cross-sectional. Setting Participants were recruited from communities in Neiva, Colombia. Participants Thirty children with SCI/D and their primary caregiver participated. Children were between 8 and 17 years of age, and had sustained their injury at least six months prior to data collection. Interventions NA. Outcome measures Participating children completed measures assessing their own psychosocial functioning (Children's Depression Inventory, Revised Children's Manifest Anxiety Scale-2, Pediatric Quality of Life Inventory), and their primary caregiver completed measures of family dynamics (Family Adaptability and Cohesion Evaluation Scale- Fourth Edition, Family Communication Scale, Family Assessment Device- General Functioning, Family Satisfaction Scale, Relationship-Focused Coping Scale). Results A correlation matrix showed a number of significant bivariate correlations between child and family variables, and three multiple regressions showed that family satisfaction, empathy, and flexibility significantly explained 27% of the variance in child worry; family satisfaction and communication explained 18% of the variance in child social anxiety; and family cohesion and communication explained 23% of the variance in child emotional functioning. Conclusions These findings highlight the importance of rehabilitation professionals considering the association between family dynamics and the psychosocial functioning of children with SCI/D when working with this population.

    To study long-term effects of psychosocial work stress in mid-life on health functioning after labor market exit using two established work stress models. In the frame of the prospective French Gazel cohort study, data on psychosocial work stress were assessed using the full questionnaires measuring the demand-control-support model (in 1997 and 1999) and the effort-reward imbalance model (in 1998). In 2007, health functioning was assessed, using the Short Form 36 mental and physical component scores. Multivariate regressions were calculated to predict health functioning in 2007, controlling for age, gender, social position, and baseline self-perceived health. Consistent effects of both work stress models and their single components on mental and physical health functioning during retirement were observed. Effects remained significant after adjustment including baseline self-perceived health. Whereas the predictive power of both work stress models was similar in the case of the physical composite score, in the case of the mental health score, values of model fit were slightly higher for the effort-reward imbalance model (R(2): 0.13) compared with the demand-control model (R²: 0.11). Findings underline the importance of working conditions in midlife not only for health in midlife but also for health functioning after labor market exit.

    The authors examined whether 13- to 15-year-old adolescents who experience feelings of same-sex attraction (SSA) differ from those without such feelings in the quality of relationships with parents, peers, and class mentors and in psychosocial functioning (health status and school performance). The authors also assessed whether differences in psychosocial functioning resulted from differences in the quality of social relationships. Data were collected from 866 Dutch high school students (mean age 13.61 years) by means of a computer-based questionnaire. Of the participants, 74 (8.5%) reported having feelings of SSA. The participants with SSA rated the quality of their relationships with their fathers and their peers lower than did those without SSA. Participants with SSA also had poorer mental health (higher levels of depression and lower levels of self-esteem) and lower school performance. A mediation analysis revealed that differences in psychosocial functioning resulted from differences in the quality of the same-sex attracted youths' social relationships, especially with fathers and peers.

  7. Anomaly Detection with Score functions based on Nearest Neighbor Graphs

    2009-01-01

    We propose a novel non-parametric adaptive anomaly detection algorithm for high dimensional data based on score functions derived from nearest neighbor graphs on $n$-point nominal data. Anomalies are declared whenever the score of a test sample falls below $\\alpha$, which is supposed to be the desired false alarm level. The resulting anomaly detector is shown to be asymptotically optimal in that it is uniformly most powerful for the specified false alarm level, $\\alpha$, for the case when the anomaly density is a mixture of the nominal and a known density. Our algorithm is computationally efficient, being linear in dimension and quadratic in data size. It does not require choosing complicated tuning parameters or function approximation classes and it can adapt to local structure such as local change in dimensionality. We demonstrate the algorithm on both artificial and real data sets in high dimensional feature spaces.

    Chronic pain and PTSD are known to hold substantial comorbidity following traumatic injury. Although pharmacological agents have been examined in the treatment of pain and PTSD individually, little is known regarding the relationship of medication use with functioning in patients with comorbid conditions. This research examined the relationships of pain, PTSD, and medication use across physical and psychosocial functioning in patients with chronic pain following motor vehicle injury (N=234). Separate analyses were conducted for opioids, SSRIs, and sedative/anxiolytics, respectively. Several relevant effects were noted: (1) Pain evidenced strong associations with reduced functioning across both physical and psychosocial domains, (2) Opioid use held interactive relationships with PTSD across both functioning domains. Specifically, opioids were associated with greater physical impairment in patients without comorbid PTSD. Opioids also were related to greater psychosocial impairment in patients without PTSD while PTSD was associated with greater impairment in patients not using opioids, (3) Opioid use evidenced a marginal interaction with pain on psychosocial functioning. Opioids were associated with greater psychosocial impairment among patients with high-pain, and high-pain was associated with greater impairment among opioid users, (4) SSRIs held a marginal interaction with PTSD such that PTSD was related to poorer psychosocial functioning only among individuals not using an SSRI, and (5) Anxiolytic use evidenced a marginal interaction with PTSD on physical functioning although no between-group differences were noted. These data suggest that PTSD symptomology may be an important consideration in determining treatment modality for patients experiencing pain subsequent to traumatic injury.

    We examine the problem of transmembrane protein structure determination. Like many other questions that arise in biological research, this problem cannot be addressed by traditional laboratory experimentation alone. An approach that integrates experiment and computation is required. We investigate a procedure which states the transmembrane protein structure determination problem as a bound constrained optimization problem using a special empirical scoring function, called Bundler, as the objective function. In this paper, we describe the optimization problem and some of its mathematical properties. We compare and contrast results obtained using two different derivative free optimization algorithms.

    The EMP(3)OWER™ study evaluated spinal cord stimulation (SCS) safety and efficacy and the associated changes in psychosocial and functional outcomes. Upon informed consent and IRB approval, 620 eligible subjects were enrolled prior to SCS trial evaluation and were assessed at baseline, 3, 6 and 12 months post-implant. Patient-reported pain relief (PRP), numerical rating scale (NRS), satisfaction, quality of life (QOL), and pain disability index (PDI) were assessed at all follow-up visits while the pain catastrophizing scale (PCS), short form-36 (SF-36), short form-McGill pain questionnaire version 2 (SF-MPQ-2), and the state-trait anxiety inventory (STAI) were assessed at the 6- and 12-month follow-up visits. Device and/or procedure-related adverse events were also recorded and reported. Subjects reporting a PRP ≥ 50% were considered responders. Repeated measures analysis of variance (RMANOVA) examined the changes across time for all continuous measures. A total of 401 (71%) subjects received a permanent implant. Mean (±SD) patient-reported pain relief was 59.3% (±26.2), 59.2% (±28.9), and 58.2% (±32.0) at 3, 6, and 12 months, respectively. A majority of enrolled subjects were responders at 3 (75.5%), 6 (74.7%), and 12 months (69.7%). RMANOVA revealed a statistically significant change for NRS, PCS, PDI, SF-36, SF-MPQ-2, and STAI scores. At 3 months, the majority of subjects (85.7%) were either very satisfied or satisfied with their device, with similar results at 6 and 12 months. At 3 months, the majority of subjects (73.3%) reported greatly improved or improved QOL with similar results at 6 and 12 months. Spinal cord stimulation provided pain relief and significant improvement of patient psychological and functional outcome measures. © 2016 American Academy of Pain Medicine. All rights reserved.

    Cannabis use and depressive disorders are thought to impair cognitive performance and psychosocial functioning. Both disorders co-occurring may compound the negative effects of these diagnoses. In this study, the authors used the California Computerized Assessment Package as the cognitive performance measure and the Addiction Severity Index as the psychosocial functioning measure to compare individuals who were cannabis dependent and either depressed or not depressed (N= 108: 54 cannabis dependent only, 54 cannabis dependent and depressed or dysthymic). As predicted, cannabis dependent individuals with comorbid depression showed more psychosocial impairment than individuals with cannabis dependence alone. However, contrary to the authors' hypothesis, individuals who were cannabis dependent with comorbid depression showed less cognitive impairment in some California Computerized Assessment Package modules than individuals with cannabis dependence alone. Based on the authors' results, they concluded that the additive effects of cannabis dependency and depression may only be limited to psychosocial domains and may not extend to cognitive functioning.

    Among the variety of methods used to evaluate locomotor function following a spinal cord injury (SCI), the Basso Mouse Scale score (BMS) has been widely used for mice. However, the BMS mainly focuses on hindlimb movement rather than on graded changes in body support ability. In addition, some of the scoring methods include double or triple criteria within a single score, which likely leads to an increase in the deviation within the data. Therefore we aimed to establish a new scoring method reliable and easy to perform in mice with SCI. Our Toyama Mouse Score (TMS) was established by rearranging and simplifying the BMS score and combining it with the Body Support Scale score (BSS). The TMS reflects changes in both body support ability and hindlimb movement. The definition of single score is made by combing multiple criteria in the BMS. The ambiguity was improved in the TMS. Using contusive SCI mice, hindlimb function was measured using the TMS, BMS and BSS systems. The TMS could distinguish changes in hindlimb movements that were evaluated as the same score by the BMS. An analysis of the coefficient of variation (CV) of score points recorded for 11 days revealed that the CV for the TMS was significantly lower than the CV obtained using the BMS. A variation in intra evaluators was lower in the TMS than in the BMS. These results suggest that the TMS may be useful as a new reliable method for scoring locomotor function for SCI models.

    Full Text Available Central precocious puberty (CPP develops due to premature activation of the hypothalamic-pituitary-gonadal (HPG axis, resulting in early pubertal changes and rapid bone maturation. CPP is associated with lower adult height and increased risk for development of psychological problems. Standard treatment of CPP is based on postponement of pubertal development by blockade of the HPG axis with gonadotropin releasing hormone analogs (GnRHa leading to abolition of gonadal sex hormones synthesis. Whereas the hormonal and auxological effects of GnRHa are well researched, there is a lack of knowledge whether GnRHa treatment influences psychological functioning of treated children, despite the fact that prevention of psychological problems is used as one of the main reasons for treatment initiation. In the present study we seek to address this issue by exploring differences in cognitive function, behavior, emotional reactivity, and psychosocial problems between GnRHa treated CPP girls and age-matched controls.Fifteen girls with idiopathic CPP; median age 10.4 years, treated with slow-release GnRHa (triptorelin acetate – Decapeptyl SR ® 11.25 and 15 age-matched controls, were assessed with a comprehensive test battery consisting of paper and pencil tests, computerized tasks, behavioral paradigms, heart rate variability, and questionnaires filled in by the children’s parents. Both groups showed very similar scores with regard to cognitive performance, behavioral and psychosocial problems. Compared to controls, treated girls displayed significantly higher emotional reactivity (p = 0.016; Cohen’s d = 1.04 on one of the two emotional reactivity task conditions. Unexpectedly, the CPP group showed significantly lower resting heart rates than the controls (p = 0.004; Cohen’s d = 1.03; lower heart rate was associated with longer treatment duration (r = - 0.582, p = 0.037. The results suggest that GnRHa treated CPP girls do not differ in their cognitive or

    The aim of the present study was to assess the relationship between illness-related characteristics, such as symptom severity and psychosocial functioning, and specific aspects of family functioning both in patients experiencing their first episode of psychosis (FEP) and chronically ill patients. A total of 50 FEP and 50 chronic patients diagnosed with schizophrenia or bipolar disorder (most recent episode manic severe with psychotic features) and their family caregivers participated in the study. Family functioning was evaluated in terms of cohesion and flexibility (FACES IV Package), expressed emotion (FQ), family burden (FBS) and caregivers' psychological distress (GHQ-28). Patients' symptom severity (BPRS) and psychosocial functioning (GAS) were assessed by their treating psychiatrist within 2 weeks from the caregivers' assessment. Increased symptom severity was associated with greater dysfunction in terms of family cohesion and flexibility (β coefficient -0.13; 95 % CI -0.23, -0.03), increased caregivers' EE levels on the form of emotional overinvolvement (β coefficient 1.03; 95 % CI 0.02, 2.03), and psychological distress (β coefficient 3.37; 95 % CI 1.29, 5.45). Family burden was found to be significantly related to both symptom severity (β coefficient 3.01; 95 % CI 1.50, 4.51) and patient's functioning (β coefficient -2.04; 95 % CI -3.55, -0.53). No significant interaction effect of chronicity was observed in the afore-mentioned associations. These findings indicate that severe psychopathology and patient's low psychosocial functioning are associated with poor family functioning. It appears that the effect for family function is significant from the early stages of the illness. Thus, early psychoeducational interventions should focus on patients with severe symptomatology and impaired functioning and their families.

    Probabilistic sensitivities provide an important insight in reliability analysis and often crucial towards understanding the physical behaviour underlying failure and modifying the design to mitigate and manage risk. This article presents a new computational approach for calculating stochastic sensitivities of mechanical systems with respect to distribution parameters of random variables. The method involves high dimensional model representation and score functions associated with probability distribution of a random input. The proposed approach facilitates first-and second-order approximation of stochastic sensitivity measures and statistical simulation. The formulation is general such that any simulation method can be used for the computation such as Monte Carlo, importance sampling, Latin hypercube, etc. Both the probabilistic response and its sensitivities can be estimated from a single probabilistic analysis, without requiring gradients of performance function. Numerical results indicate that the proposed method provides accurate and computationally efficient estimates of sensitivities of statistical moments or reliability of structural system.

    Individuals with binge eating disorder (BED) report smoking to control appetite and weight. Smoking in BED is associated with increased risk for comorbid psychiatric disorders, but its impact on psychosocial functioning and metabolic function has not been evaluated. Participants were 429 treatment-seeking adults (72.4% women; mean age 46.2±11.0years old) with BED comorbid with obesity. Participants were categorized into current smokers (n=66), former smokers (n=145), and never smokers (n=218). Smoking status was unrelated to most historical eating/weight variables and to current eating disorder psychopathology. Smoking status was associated with psychiatric, psychosocial, and metabolic functioning. Compared with never smokers, current smokers were more likely to meet lifetime diagnostic criteria for alcohol (OR=5.51 [95% CI=2.46-12.33]) and substance use disorders (OR=7.05 [95% CI=3.37-14.72]), poorer current physical quality of life, and increased risk for metabolic syndrome (OR=1.80 [95% CI=0.97-3.35]) and related metabolic risks (reduced HDL, elevated total cholesterol). On the other hand, the odds of meeting criteria for lifetime psychiatric comorbidity or metabolic abnormalities were not significantly greater in former smokers, relative to never smokers. Our findings suggest the importance of promoting smoking cessation in treatment-seeking patients with BED and obesity for its potential long-term implications for psychiatric and metabolic functioning.

    Full Text Available OBJECTIVE: The possible contributions of psychosocial functioning and intelligence differences to socioeconomic status (SES-related inequalities in premature death were investigated. None of the previous studies focusing on inequalities in mortality has included measures of both psychosocial functioning and intelligence. METHODS: The study was based on a cohort of 49 321 men born 1949-1951 from the general community in Sweden. Data on psychosocial functioning and intelligence from military conscription at ∼18 years of age were linked with register data on education, occupational class, and income at 35-39 years of age. Psychosocial functioning was rated by psychologists as a summary measure of differences in level of activity, power of initiative, independence, and emotional stability. Intelligence was measured through a multidimensional test. Causes of death between 40 and 57 years of age were followed in registers. RESULTS: The estimated inequalities in all-cause mortality by education and occupational class were attenuated with 32% (95% confidence interval: 20-45% and 41% (29-52% after adjustments for individual psychological differences; both psychosocial functioning and intelligence contributed to account for the inequalities. The inequalities in cardiovascular and injury mortality were attenuated by as much as 51% (24-76% and 52% (35-68% after the same adjustments, and the inequalities in alcohol-related mortality were attenuated by up to 33% (8-59%. Less of the inequalities were accounted for when those were measured by level of income, with which intelligence had a weaker correlation. The small SES-related inequalities in cancer mortality were not attenuated by adjustment for intelligence. CONCLUSIONS: Differences in psychosocial functioning and intelligence might both contribute to the explanation of observed SES-related inequalities in premature death, but the magnitude of their contributions likely varies with measure of

    Little is known about the correlates of comorbid drug and alcohol dependence in people with schizophrenia outside the USA. We tested hypotheses that dependence on alcohol/drugs would be associated with more severe symptoms, and poorer psychosocial functioning and quality of life. The EuroSC Cohort study (N=1204), based in France, Germany and the UK, used semi-structured clinical interviews for diagnoses, and standardized tools to assess correlates. We used mixed models to compare outcomes between past-year comorbid dependence on alcohol/drugs, controlling for covariates and modelling both subject and country-level effects. Participants dependent on alcohol or drugs had fewer negative symptoms on PANSS than their non-dependent counterparts. However, those dependent on alcohol scored higher on PANSS general psychopathology than those who were not, or dependent only on drugs. People with schizophrenia dependent on drugs had poorer quality of life, more extrapyramidal side effects, and scored worse on Global Assessment of Functioning (GAF) than those without dependence. People with alcohol dependence reported more reasons for non-compliance with medication, and poorer functioning on GAF, though not on Global Assessment of Relational Functioning. In people with schizophrenia, comorbid dependence on alcohol or drugs is associated with impaired clinical and psychosocial adjustment, and poorer quality of life.

    Study Design Retrospective cross-sectional cohort of military patients with musculoskeletal pain. Background Body diagrams are used to document symptoms and can also serve as a proxy to assess psychological influence. However, literature to support this is conflicting. Objectives To (1) examine the unique contribution of pain and nonpain symptom distribution to magnitude of self-reported pain intensity and disability, and (2) assess the moderating influence of psychological factors and body diagram score on concurrent pain intensity and disability. Methods Pain, numbness, and tingling were denoted on a body diagram at initial evaluation. Fear-avoidance beliefs, pain catastrophizing, and region-specific self-reported disability measures were collected. The contributions of pain and nonpain symptom distribution to pain intensity and disability were assessed to determine which body diagram symptom scoring method (pain only, nonpain, or composite) was appropriate for subsequent analyses. Hierarchical linear regression analyses were then used to determine the moderating effects of the Pain Catastrophizing Scale and Fear-Avoidance Beliefs Questionnaire and the body diagram score on concurrent pain and disability. Results The Pain Catastrophizing Scale and Fear-Avoidance Beliefs Questionnaire explained between 16% and 17% of the variance in pain intensity, and 8% of variance in disability (all, Pintensity (all, Pintensity. The positive relationship between composite symptom score and concurrent pain intensity is stronger for patients with low catastrophizing. Conclusion The clinical utility of body diagrams with low symptom distribution may be improved by concomitant assessment of pain catastrophizing and warrants further longitudinal investigation.

    Introduction Somatic symptoms are frequently reported by children with significant impairment in functioning. Despite studies on adult populations that suggest somatic symptoms often co-occur with difficulties in identifying and describing feelings, little research has been done in childhood. This study aimed to investigate the prevalence and frequency of somatic symptoms as well as to investigate the functional impairment in children with high number of self reported somatic symptoms versus those with fewer somatic symptoms. Additionally the parental perception of their children's somatic symptoms and functioning was explored. Finally, we explored the direct and indirect effects of difficulties in identifying feelings in predicting somatic symptoms and functional disability among school-aged children. Methods 356 Italian school-aged children and their mothers participated in this study. Children (mean age = 11.43; SD = 2.41) completed the Children’s Somatization Inventory (CSI-24) to assess somatic symptoms, the Functional Disability Inventory (FDI) to assess physical and psychosocial functioning and the Alexithymia Questionnaire for Children (AQC) to evaluate alexithymic features. Mothers completed the parental forms of the CSI and the FDI. Results Among children, 66.3% did not declare somatic symptoms and 33.7% reported one or more somatic symptoms in the last two weeks. A significant positive correlation emerged between children’s and mothers’ CSI total scores. Both children’s and mothers’ FDI total scores were significantly correlated with CSI scores. A significant correlation was observed between somatic symptoms and alexithymic features. Furthermore, the data showed that somatic symptoms mediated the relationship between difficulties in identifying feelings and functional impairment. Finally, it was showed that alexithymia facet of difficulty in identifying feelings contributed in large part to the prediction of the somatic symptomatology (b = 0

Clinical and psychosocial measures have been recently introduced to assess functional outcome.Objective: The study presented here was designed to examine the rates of symptomatic remission, psychosocial remission, global functioning, and clinical global impressions in a sample of schizophrenia outpatients in order to assess functional remission and to identify predictive factors for functional remission.Methods: A total of 168 consecutive Mexican outpatients receiving pharmacological treatment at the National Institute of Psychiatry in Mexico City were enrolled in a cross-sectional study. Symptomatic remission was assessed according to the definition and criteria proposed by the Remission in Schizophrenia Working Group using the Positive and Negative Symptom Scale. Psychosocial remission was assessed according to Barak criteria using the Psychosocial Remission in Schizophrenia scale. Functioning was measured with the Global Assessment of Functioning, and clinical outcome with the Clinical Global Impressions (CGI Scale.Results: Findings showed that 45.2% of patients fulfilled the symptomatic remission criteria, 32.1% achieved psychosocial remission, and 53% reported adequate functioning.

    Families who experience a chronic complex of socio-economic and psychosocial problems are hard to reach with mainstream care. Evidence exists that the core of this problem is a problematic interaction between this type of family and current systems of care and services. To improve access to problem families, an assertive outreach intervention was implemented into the field of preventive child health care, The Netherlands. The study aimed to provide a more detailed insight into characteristics of the target group. Although there is consensus about some general features of hard to reach problem families, little is known about their specific characteristics because empirical studies among this group are rarely conducted. Especially, the problems of the children is shed insufficient light on. The studied population consisted of families included in the assertive outreach intervention delivered during one year (N=116). To assess psychosocial adjustment of the children, the Strengths and Difficulties Questionnaire was filled in by the parents. Furthermore, a Dutch questionnaire on family functioning was completed by professional carers. Descriptive data were calculated. The findings show that by using the assertive outreach intervention, programme staff came into contact with families characterised by a considerably higher than average proportion of single parents and unemployed households receiving social benefits. The families faced a high level of risk and a wide range of severe and multiple difficulties, including a lack of basic child care, an inadequate social network and poor parenting. Children in these families were also facing a number of risks. The proportion of psychosocial problems was well above the (inter)national average. The findings reveal the problem areas of unreached families and a need to improve the access to care for these families.

    To examine the relationships between stressful life events and physiological measures, adherence to prescribed oral medication regimens, depressive symptoms, and impaired quality of life (QoL) in adolescents with recent-onset type 2 diabetes (T2D). Data were collected from 497 ethnically diverse participants (66% female) in the final year of the Treatment Options for Type 2 Diabetes in Adolescents and Youth multicenter clinical trial. Exposure to 32 possible events over the previous year and rating of subsequent distress were collected by self-report and summarized as a major stressors score. This score was analyzed for relationship to glycemic control (hemoglobin A1c and treatment failure), body mass index, diagnosis of hypertension or triglyceride dyslipidemia, adherence to a prescribed oral medication regimen, presence of depressive symptoms, and impaired QoL. The total number of major stressful life events in the adolescents with T2D was calculated, with 33% reporting none, 67% reporting ≥ 1, 47% reporting ≥ 2, 33% reporting ≥ 3, and 20% reporting ≥ 4. There were no associations between the major stressors score and physiological measures or diagnosis of comorbidities. The odds of medication nonadherence increased significantly from those reporting ≥ 1 major stressor (OR, 1.58; P = .0265) to those reporting ≥ 4 major stressors (OR, 2.70; P = .0009). Significant odds of elevated depressive symptoms and impaired QoL were also found with increased reporting of major stressors. Exposure to major stressful life events is associated with lower adherence to prescribed oral medication regimens and impaired psychosocial functioning in adolescents with T2D.

    Background:The prognostic values of the coronary computed tomography angiography (CCTA) score for predicting future cardiovascular events have been previously demonstrated in numerous studies.However,few studies have used the rich information available from CCTA to detect functionally significant coronary lesions.We sought to compare the prognostic values of Gai's plaque score and the coronary artery calcium score (CACS) of CCTA for predicting functionally significant coronary lesions,using fractional flow reserve (FFR) as the gold standard.Methods:We retrospectively analyzed 107 visually assessed significant coronary lesions in 88 patients (mean age,59.6 ± 10.2 years;76.14% of males) who underwent CCTA,invasive coronary angiography,and invasive FFR measurement.An FFR <0.80 indicated hemodynamically significant coronary stenosis.Lesions were divided into two groups using an FFR cutoff value of 0.80.We compared Gai's plaque scores and CACS between the two groups and evaluated the correlations of these scores with FFR.The statistical methods included unpaired t-test,Mann-Whitney U-test,and Spearman's correlation coefficients.Results:Coronary lesions with FFR <0.80 had higher Gai's scores than those with FFR ≥0.80.Gai's score had the strongest correlation with FFR (r =-0.48,P < 0.01) and had a greater area under the curve =0.72 (95% confidence interval:0.61-0.82;P < 0.01) than the CACS of whole arteries and a single artery.Conclusions:Both CACS in a single artery and Gai's plaque score demonstrated a good capacity to assess functionally significant coronary artery stenosis when compared to the gold standard FFR.However,Gai's plaque score was more predictive of FFR <0.80.Gai's score can be easily calculated in daily clinical practice and could be used when considering revascularization.

    In this report we review the data on 75 male patients with extra Y chromosome diagnosed in Leuven in the period 1968-1993 among 98,725 patients (males and females) referred for constitutional chromosomal analysis. Special attention was given to their mental performance and psychosocial functioning. 1. Fifty male with 47,XYY karyotype were diagnosed. This is very close to the incidence of XYY in newborn studies and indicates that the frequency of MR/MCA is not increased in XYY male in general. 2. In the 60 patients with "pure" Y chromosome polysomy, the most frequent indication for karyotyping was the presence of MR and/or characterological problems in the index patients. Mental retardation was mostly borderline to mild, and severe mental retardation was rare. Characterological problems, difficulties in psychosocial integration and psychiatric problems were found in 86% of the mentally retarded versus 24% of the mentally normal men. 3. The 48,XXYY syndrome is characterized by markedly frequent and severe behavioural and psychiatric problems.

    Full Text Available Abstract Background Prostate cancer is the most commonly diagnosed non-melanoma cancer among men. Androgen deprivation therapy (ADT has been the core therapy for men with advanced prostate cancer. It is only in recent years that clinicians began to recognize the cognitive-psychosocial side effects from ADT, which significantly compromise the quality of life of prostate cancer survivors. The objectives of the study are to determine the efficacy of a simple and accessible home-based, walking exercise program in promoting cognitive and psychosocial functions of men with prostate cancer receiving ADT. Methods A 6-month prospective, single-blinded, randomized controlled trial will be conducted to compare the Exercise Group with the Control Group. Twenty men with prostate cancer starting ADT will be recruited and randomly assigned to one of the two groups: the Exercise Group will receive instructions in setting up an individualized 6-month home-based, walking exercise program, while the Control Group will receive standard medical advice from the attending physician. The primary outcomes will be psychosocial and cognitive functions. Cognitive functions including memory, attention, working memory, and executive function will be assessed using a battery of neurocognitive tests at baseline and 6 months. Psychosocial functions including depression, anxiety and self-esteem will be assessed at baseline, 3 and 6 months using the Center for Epidemiological Studies Depression Scale, Spielberger State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale. Discussion The significance of the cognitive-psychosocial side effects of ADT in men with prostate cancer has only been recently recognized, and the management remains unclear. This study addresses this issue by designing a simple and accessible home-based, exercise program that may potentially have significant impact on reducing the cognitive and psychosocial side effects of ADT, and ultimately

    Full Text Available Background and Objectives: Although studied extensively among adults, self-rated health (SRH has not received the same research attention among adolescents. It has been suggested that SRH in adolescents may be a function of adolescents' overall sense of functioning and may reflect psychosocial functioning more so than in adults. The rating of health as poor by adolescents might be a somatic expression of life distress and may be connected with risky behaviors. Therefore, the purpose of this study was to investigate self-rated health (SRH in Central and Eastern European (CEE adolescents and determine its association with psychosocial functioning and other dimensions of adolescent health. Methods: A survey was administered to 3,123 students in 34 secondary schools across CEE which included measures of SRH, psychosocial functioning (loneliness, hopelessness, shyness, perceptions of social status, self-rated happiness, and perception of physical attractiveness, and other dimensions of adolescent health (height/weight, physical activity, eating breakfast, sleep. Results: More girls (19.4 % than boys (11.3 % rated themselves as "not healthy" and this was true in each of the six countries. Significant predictors of SRH in the logistic regression model were gender, country of residence, hopelessness, shyness, subjective social status-society, self-rated happiness, perception of physical attractiveness, vigorous physical activity, eating breakfast, overweight status, and usually get 7-8 hours or more sleep a night. Conclusions: SRH appears to be associated with psychosocial functioning and other dimensions of adolescent health in CEE youth.

    The current study examined how parental ethnic socialization informed adolescents' ethnic identity development and, in turn, youths' psychosocial functioning (i.e., mental health, social competence, academic efficacy, externalizing behaviors) among 749 Mexican-origin families. In addition, school ethnic composition was examined as a moderator of these associations. Findings indicated that mothers' and fathers' ethnic socialization were significant longitudinal predictors of adolescents' ethnic identity, although fathers' ethnic socialization interacted significantly with youths' school ethnic composition in 5(th) grade to influence ethnic identity in 7(th) grade. Furthermore, adolescents' ethnic identity was significantly associated with increased academic self-efficacy and social competence, and decreased depressive symptoms and externalizing behaviors. Findings support theoretical predictions regarding the central role parents play in Mexican-origin adolescents' normative developmental processes and adjustment and, importantly, underscore the need to consider variability that is introduced into these processes by features of the social context such as school ethnic composition.

The Global Assessment of Functioning (GAF-F scale represents a widely applied, easy, and quick tool, but its validity and reliability have been debated. The aim was to investigate whether GAF-F scores are associated with other indicators of functioning, severity, and hospitalization.Methods: A Danish population-based cohort study of adults (≥18 years with a recorded GAF-F score at first-time schizophrenia diagnosis during 2004–2011 was performed. The internal validity of GAF-F was evaluated by assessing its association with other baseline measures of functioning and illness severity. Risk of schizophrenia hospitalization within 2 years was evaluated using Cox regression stratified by sex and adjusted for age, year of diagnosis, and inpatient/outpatient status at diagnosis.Results: We identified 2,837 cases of schizophrenia with a GAF-F score at first-time diagnosis (73.0% inpatients; 62.6% males. GAF-F was associated with several baseline measures of functioning and illness severity, such as female sex, being in work, and a longer baseline hospitalization.

    Full Text Available The article focuses on the problem of measuring emotional intelligence in children and adolescents and on the connection between the construct of emotional intelligence and some aspects of psychosocial functioning in elementary and secondary school pupils. Basically there are two main approaches to the measurement of emotional intelligence: the first approach comprehends emotional intelligence as an ability and the second approach as a range of personality traits. In our research we used BarOn Emotional Quotient Inventory: Youth Version (EQ-i:YV, 2000, which measures emotional intelligence as a personality trait. The purpose of the article is twofold: first, to check the psychometric characteristics of the questionnaire, and second, to establish the connection between emotional intelligence and some indicators of psychosocial functioning - social acceptance of the pupils in the class, different dimensions of self-concept and the perceptions of the pupils from their schoolmates on different fields of behavior. On the sample of 282 pupils we have found out that EQ-i:YV has an appropriate reliability and factorial validity, but the construct validity of the instrument is questionable. Emotional intelligence as measured by the questionnaire we have used is not significantly connected with measures of social acceptance and perceptions of the pupils from their peers in different fields of behavior. We established a significant connection between measures of emotional intelligence and the pupil's self-concept. Our results confirm the findings of other authors that in further investigation of emotional intelligence the instruments which measure emotional intelligence as an ability should be developed.

    Foster care is the preferred alternative for out-of-home care, but not necessarily beneficial for foster children's psychosocial functioning. This dilemma leaves researchers with a challenge to find out more about the factors related to foster children's social and emotional functioning. In a sample of 446 Dutch foster children we examined the extent to which three clusters of characteristics, those akin to the foster child, the foster family, or foster placement, were related to foster children's functioning at the time of research. Multivariate three-step hierarchical regression analyses were performed for three outcome variables: externalizing problems, internalizing problems, and prosocial behavior. We found that all three clusters of foster care characteristics were significantly related to foster children's functioning. Foster placement characteristics, in particular interventions aimed at foster children, explained the largest amount of variance in behavior problems. Children receiving interventions had more externalizing and internalizing problems. A possible explanation is that interventions are indicated for those foster children who are in the highest need of additional support. Prosocial behavior was particularly related to foster family characteristics. The results were mostly in line with international research. Careful screening and monitoring of the social and emotional functioning of foster children may help to identify problems at an early stage. In addition (preventive) support should be offered to those foster children and families who are in need of it. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-05-01

    These data suggest that conventional whole-word scoring may significantly underestimate functional spelling performance. Because by-letter scoring boosted pre-treatment scores to the same extent as post-treatment scores, the magnitude of treatment gains was no greater than estimates from conventional whole-word scoring. Nonetheless, the surprisingly large disparity between conventional whole-word scoring and by-letter scoring suggests that by-letter scoring methods may warrant further investigation. Because by-letter analyses may hold interest to others, we plan to make the software tool used in this study available on-line for use to researchers and clinicians at large.

    Use of knowledge based scoring function (KBSF) for virtual screening and molecular docking has become an established method for drug discovery. Lack of a precise and reliable free energy function that describes several interactions including water-mediated atomic interaction between amino-acid residues and ligand makes distance based statistical measure as the only alternative. Till now all the distance based scoring functions in KBSF arena use atom singularity concept, which neglects the environmental effect of the atom under consideration. We have developed a novel knowledge-based statistical energy function for protein-ligand complexes which takes atomic environment in to account hence functional group as a singular entity. The proposed knowledge based scoring function is fast, simple to construct, easy to use and moreover it tackle the existing problem of handling molecular orientation in active site pocket. We have designed and used Functional group based Ligand retrieval (FBLR) system which can identify and detect the orientation of functional groups in ligand. This decoy searching was used to build the above KBSF to quantify the activity and affinity of high resolution protein-ligand complexes. We have proposed the probable use of these decoys in molecular build-up as a de-novo drug designing approach. We have also discussed the possible use of the said KSBF in pharmacophore fragment detection and pseudo center based fragment alignment procedure. PMID:19255647

    Full Text Available The distance-dependent knowledge-based DrugScore(PPI potentials, previously developed for in silico alanine scanning and hot spot prediction on given structures of protein-protein complexes, are evaluated as a scoring and objective function for the structure prediction of protein-protein complexes. When applied for ranking "unbound perturbation" ("unbound docking" decoys generated by Baker and coworkers a 4-fold (1.5-fold enrichment of acceptable docking solutions in the top ranks compared to a random selection is found. When applied as an objective function in FRODOCK for bound protein-protein docking on 97 complexes of the ZDOCK benchmark 3.0, DrugScore(PPI/FRODOCK finds up to 10% (15% more high accuracy solutions in the top 1 (top 10 predictions than the original FRODOCK implementation. When used as an objective function for global unbound protein-protein docking, fair docking success rates are obtained, which improve by ∼ 2-fold to 18% (58% for an at least acceptable solution in the top 10 (top 100 predictions when performing knowledge-driven unbound docking. This suggests that DrugScore(PPI balances well several different types of interactions important for protein-protein recognition. The results are discussed in view of the influence of crystal packing and the type of protein-protein complex docked. Finally, a simple criterion is provided with which to estimate a priori if unbound docking with DrugScore(PPI/FRODOCK will be successful.

    The use of cannabis during the early stage of psychosis has been linked with increased psychotic symptoms. This study aimed to examine the use of cannabis in the 12 months following a first-episode of psychosis (FEP) and the link with symptomatic course and outcome over 1 year post psychosis onset. One thousand twenty-seven FEP patients were recruited upon inception to specialized early intervention services (EIS) for psychosis in the United Kingdom. Participants completed assessments at baseline, 6 and 12 months. The results indicate that the use of cannabis was significantly associated with increased severity of psychotic symptoms, mania, depression and poorer psychosocial functioning. Continued use of cannabis following the FEP was associated with poorer outcome at 1 year for Positive and Negative Syndrome Scale total score, negative psychotic symptoms, depression and psychosocial functioning, an effect not explained by age, gender, duration of untreated psychosis, age of psychosis onset, ethnicity or other substance use. This is the largest cohort study of FEP patients receiving care within EIS. Cannabis use, particularly "continued use," was associated with poorer symptomatic and functional outcome during the FEP. The results highlight the need for effective and early intervention for cannabis use in FEP. © The Author 2015.

    Chronic benzodiazepine use is common in patients with mental illness and is associated with cognitive impairment. It is unclear whether benzodiazepine-induced cognitive impairment is reversible. Amelioration of cognitive dysfunction may be facilitated during benzodiazepine tapering by add-on melatonin due to its anti-inflammatory and neuroprotective properties. We examined how melatonin and benzodiazepine withdrawal affect cognition, subjective well-being, and psychosocial functioning. Eighty patients with schizophrenia or bipolar disorder were randomized to add-on treatment once daily with either prolonged-release melatonin or placebo in a 24-week, double-blind clinical trial. All participants gradually tapered usual benzodiazepine dosage in a closely monitored treatment setting. We used the Brief Assessment of Cognition in Schizophrenia (BACS) to assess neurocognitive performance with additional assessments of subjective well-being and psychosocial functioning. BACS composite and subscale scores (except motor speed) significantly improved in parallel with benzodiazepine dose reduction, but there was no additional effect of melatonin. Cognitive performance was still markedly impaired post-tapering compared with normative data. Neither benzodiazepine withdrawal nor treatment group affected subjective well-being or psychosocial functioning. In conclusion, add-on melatonin does not seem to affect cognition, well-being, or psychosocial functioning in patients with severe mental illness. The observed improvement in cognitive performance could not be distinguished from retest effects, which may in turn have been facilitated by the benzodiazepine tapering.

  13. Feeling well and talking about sex: psycho-social predictors of sexual functioning after cancer

    Science.gov (United States)

    2014-01-01

    Background Changes to sexual wellbeing are acknowledged to be a long-term negative consequence of cancer and cancer treatment. These changes can have a negative effect on psychological well-being, quality of life and couple relationships. Whilst previous conclusions are based on univariate analysis, multivariate research can facilitate examination of the complex interaction between sexual function and psycho-social variables such as psychological wellbeing, quality of life, and relationship satisfaction and communication in the context of cancer, the aim of the present study. Method Six hundred and fifty seven people with cancer (535 women, 122 men) and 148 partners (87 women, 61 men), across a range of sexual and non-sexual cancers, completed a survey consisting of standardized measures of sexual functioning, depression and anxiety, quality of life, relationship satisfaction, dyadic sexual communication, and self-silencing, as well as ratings of the importance of sex to life and relationships. Results Men and women participants, reported reductions in sexual functioning after cancer across cancer type, for both people with cancer and partners. Multiple regression analysis examined psycho-social predictors of sexual functioning. Physical quality of life was a predictor for men and women with cancer, and for male partners. Dyadic sexual communication was a predictor for women with cancer, and for men and women partners. Mental quality of life and depression were also predictors for women with cancer, and the lower self-sacrifice subscale of self-silencing a predictor for men with cancer. Conclusion These results suggest that information and supportive interventions developed to alleviate sexual difficulties and facilitate sexual renegotiation should be offered to men and women with both sexual and non-sexual cancers, rather than primarily focused on individuals with sexual and reproductive cancers, as is the case currently. It is also important to include partners

  16. Comparative assessment of scoring functions on an updated benchmark: 2. Evaluation methods and general results.

    Our comparative assessment of scoring functions (CASF) benchmark is created to provide an objective evaluation of current scoring functions. The key idea of CASF is to compare the general performance of scoring functions on a diverse set of protein-ligand complexes. In order to avoid testing scoring functions in the context of molecular docking, the scoring process is separated from the docking (or sampling) process by using ensembles of ligand binding poses that are generated in prior. Here, we describe the technical methods and evaluation results of the latest CASF-2013 study. The PDBbind core set (version 2013) was employed as the primary test set in this study, which consists of 195 protein-ligand complexes with high-quality three-dimensional structures and reliable binding constants. A panel of 20 scoring functions, most of which are implemented in main-stream commercial software, were evaluated in terms of "scoring power" (binding affinity prediction), "ranking power" (relative ranking prediction), "docking power" (binding pose prediction), and "screening power" (discrimination of true binders from random molecules). Our results reveal that the performance of these scoring functions is generally more promising in the docking/screening power tests than in the scoring/ranking power tests. Top-ranked scoring functions in the scoring power test, such as X-Score(HM), ChemScore@SYBYL, ChemPLP@GOLD, and PLP@DS, are also top-ranked in the ranking power test. Top-ranked scoring functions in the docking power test, such as ChemPLP@GOLD, Chemscore@GOLD, GlidScore-SP, LigScore@DS, and PLP@DS, are also top-ranked in the screening power test. Our results obtained on the entire test set and its subsets suggest that the real challenge in protein-ligand binding affinity prediction lies in polar interactions and associated desolvation effect. Nonadditive features observed among high-affinity protein-ligand complexes also need attention.

    Background Traditionally, physicians have believed that limb-salvage surgery has functional and cosmetic advantages over amputation, yet the literature is equivocal. Therefore, we sought to compare the psychosocial and functional outcomes in osteosarcoma survivors after limb-salvage surgery and amputation. We hypothesized there to be neither psychosocial nor functional outcome differences between groups. Procedure Participants received treatment of extremity osteosarcoma, had received their cancer diagnosis at least 2 years prior, and were at least 16 years old. A comprehensive set of validated psychosocial and functional measures was used to assess outcome. Results Fifty-seven patients participated in this study (33 who underwent limb-salvage surgery and 24 who underwent amputation). Participants had gone 12–24 years since diagnosis and were 16–52 years old at study participation. We used multiple linear regression models to examine differences in quality of life, body image, self-esteem, and social support between the two groups and found no differences. Lower limb function was a significant predictor of quality of life (p amputation, amputation after failed limb salvage, than by those who did not. Conclusions Participants with more functional lower limbs had better quality of life than did those with less functional lower limbs regardless of whether they underwent amputation or limb-salvage surgery.

    Introduction Sex-related differences in clinical manifestations and consequences of Parkinson’s disease (PD) have been poorly explored. Better understanding of sexual dimorphism in neurologic diseases such as PD has been announced as a research priority. The aim of our study was to determine independent sex differences in clinical manifestations and subtypes, psychosocial functioning, quality of life (QoL) and its domains between male and female individuals with PD. Patients and methods A comprehensive list of demographics, motor symptoms and subtypes, nonmotor features, health-related quality of life (HRQoL), psychosocial functioning and general aspects of daily life was assessed in 157 individuals (108 males and 49 females) with idiopathic PD. In order to control for potential confounding variables, we applied Orthogonal Partial Least Squares – Discriminant Analysis (OPLS-DA) to explore the strength of each feature to discriminate male and female patients with PD. Results While no sex difference was found in the total Unified Parkinson’s Disease Rating Scale (UPDRS) score and cumulative daily dose of levodopa, females had significantly more severe anxiety (mean difference =2.2 [95% confidence interval, CI: 0.5–4.0], P=0.011), worse nutritional status (23.8 [standard deviation, SD =4.2] vs 25.8 [SD =2.6], P=0.003) and poorer QoL (28.3 [SD =15.7] vs 17.9 [SD =14.2], P<0.001). Based on multivariate discriminant analysis, emotional well-being, bodily discomfort, social support, mobility and communication domains of HRQoL, together with anxiety, depression and psychosocial functioning, were the strongest features with more severe/worse status in females after adjustment for potential statistical confounders. Conclusion Our study provides a comprehensive understanding of sexual dimorphism in PD. Anxiety, depression, specific domains of HRQoL (mobility, emotional well-being, social support and bodily discomfort) and psychosocial functioning were significantly

    We investigated self-image, psychological functioning, and quality of life in children and adolescents with juvenile idiopathic arthritis (JIA). Thirty-nine children with JIA were compared with 80 healthy peers. We first administered the Human Figure Drawing Test (HFDT) to all subjects; children also completed standardized questionnaires evaluating health-related quality of life (PEDSQL 4.0 Generic Core Scales) and the main aspects of psychological functioning: anxiety (SAFA-A) and depression (CDI). Parents were asked to complete the Child Behaviour Checklist (CBCL) and the PEDSQL 4.0. For each patient with JIA, clinical notes were gathered and a global disease assessment (visual analog scale--VAS) was performed. Compared to healthy peers, patients with JIA reported reduced maturity quotients at HFDT, more depressive traits, greater anxiety, and lower health-related quality of life. Among the subjects with JIA, HFDT revealed that adolescents had a greater impairment in all areas investigated. Furthermore, there was a significant correlation between the physical well-being rated by VAS and the perception of poorer quality of life in patients, mostly in the psychosocial domains. Children and adolescents with JIA exhibit emotional difficulties and a delay of psychological development leading to low self-esteem, a distorted self-image, more anxiety and depression traits, and a worse quality of life, when compared to healthy subjects.

    Owing to the possible visible nature and functional impairments associated with neonatal brachial plexus injuries (NBPI), the current study investigated the relations of injury severity, social support, and coping strategies to social difficulties and self-concept in youth with NBPI. 88 children (aged 10-17 years) with NBPI and their parent(s) were recruited from a national organization and two brachial plexus clinics. Participants completed a variety of questionnaires during their scheduled clinic visits. More social support from classmates was associated with better self-concept and fewer social difficulties. Less frequent use of negative coping strategies was associated with better self-concept and fewer social difficulties and was a significant moderator of the relation between injury severity and self-concept. Clinicians who work with children with NBPI should consider peer support and coping strategies when promoting the psychosocial functioning of these youth. © The Author 2014.

    Full Text Available BackgroundChronic alcoholism and its related cognitive impairments are associated with increased social, relational, and professional deficits which have a variable overall impact on social integration. These impairments are known to have varying severities and have rarely been studied among healthy alcohol-dependent subjects with preserved psychosocial functioning. Thus, the objective of this study is to describe neuropsychological performance in this particular population.MethodTwenty-nine socially adjusted alcohol-dependent men, hospitalized for a first or second withdrawal and abstinent for 3 weeks minimum, were compared to 29 healthy non-alcoholic controls. All subjects underwent clinical and psychiatric examination, neuropsychological tests of memory (M, working memory (WM, and executive functions (EF. Comparisons were performed using Student’s t-tests or Mann–Whitney U tests.ResultsNo group differences were found on the Self-Reported Social Adjustment Scale (SAS-SR or in the Mini-Mental State Examination. Compared to controls, patients had greater episodic, spatial, and WM deficits as well as slightly altered executive functions. In contrast, their executive functions (spontaneous flexibility, criteria generation, rule maintenance, and inhibitory control were relatively preserved.ConclusionOur sample of socially and professionally integrated alcoholic patients shows fewer cognitive deficits than described in previous studies. Our results suggest that early on, alcohol-dependent subjects develop compensatory adaptation processes to preserve social function and adaptation. Minor cognitive impairments should be screened early in the disease to integrate cognitive interventions into the health-care plan to thus eventually prevent further socio-professional marginalization.

Secondary, retrospective analysis of randomized controlled trial data. Setting. Not applicable. Participants. 146 subjects with stable, chronic stroke-induced hemiparesis. Intervention. The NIHSS, the UE Fugl-Meyer (FM, and the Arm Motor Ability Test (AMAT were administered prior to their participation in a multicenter randomized controlled trial. Main Outcome Measures. The NIHSS, FM, and AMAT. Results. The association between the NIHSS and UE impairment was statistically significant (P=-0.204;p=0.014 but explained less than 4% of the variance among UE FM scores. The association between NIHSS total score and function as measured by the AMAT was not statistically significant (P=-0.141;p=0.089. Subjects scoring a “zero” on the NIHSS exhibited discernible UE motor deficits and varied scores on the UE FM and AMAT. Conclusion. While being used in stroke trials, the NIHSS may have limited ability to discriminate between treatment responses, even when only a relatively narrow array of impairment levels exists among patients. Given these findings, NIHSS use should be restricted to acute stroke studies and clinical settings with the goal of reporting stroke severity.

    Katrina D Hopkins

    Full Text Available We investigate whether the profile of factors protecting psychosocial functioning of high risk exposed Australian Aboriginal youth are the same as those promoting psychosocial functioning in low risk exposed youth. Data on 1,021 youth aged 12-17 years were drawn from the Western Australian Aboriginal Child Health Survey (WAACHS 2000-2002, a population representative survey of the health and well-being of Aboriginal children, their families and community contexts. A person-centered approach was used to define four groups of youth cross-classified according to level of risk exposure (high/low and psychosocial functioning (good/poor. Multivariate logistic regression was used to model the influence of individual, family, cultural and community factors on psychosocial outcomes separately for youth in high and low family-risk contexts. Results showed that in high family risk contexts, prosocial friendship and low area-level socioeconomic status uniquely protected psychosocial functioning. However, in low family risk contexts the perception of racism increased the likelihood of poor psychosocial functioning. For youth in both high and low risk contexts, higher self-esteem and self-regulation were associated with good psychosocial functioning although the relationship was non-linear. These findings demonstrate that an empirical resilience framework of analysis can identify potent protective processes operating uniquely in contexts of high risk and is the first to describe distinct profiles of risk, protective and promotive factors within high and low risk exposed Australian Aboriginal youth.

    Functional constipation is an issue for both the patient and his/her family, affecting the patient's psychoemotional balance, social relations, and their harmonious integration in the school environment. We aimed to highlight the connection between chronic constipation and encopresis and the patient's psychosocial and family-related situation. Material and Method. 57 patients with ages spanning from 6 to 15 were assessed within the pediatric gastroenterology ward. Sociodemographic, medical, and psychological data was recorded. The collected data was processed using the SPSS 20 software. Results. The study group consisted of 57 children diagnosed with encopresis (43 boys (75.44%) and 14 girls (24.56%)), M = 10.82 years. It was determined that most of the children came from urban families with a poor socioeducational status. We identified a level of studies of 11.23 ± 5.56 years in mothers, while fathers had an average number of 9.35 ± 4.53 years of study. We also found a complex relationship between encopretic episodes and school performances (F = 7.968, p = 0.001, 95% Cl). Children with encopresis were found to have more anxiety/depression symptoms, greater social problems, more disruptive behavior, and poorer school performance. Conclusions. The study highlights the importance of the family environment and socioeconomic factors in manifestations of chronic constipation and encopresis.

    Although loneliness is a common problem across late adolescence, its developmental course has not been investigated in depth in this period of life. The present study aims to fill this gap by means of a five-wave cohort-sequential longitudinal study spanning ages 15 to 20 (N = 389). Both variable-centered (i.e., latent growth curve modeling) and person-centered (i.e., latent class growth analysis) approaches were used. Variable-centered analyses showed that loneliness generally decreased over time. Person-centered analyses pointed to considerable inter-individual differences in the development of loneliness, and identified five trajectory classes (i.e., stable low, low increasing, moderate decreasing, high increasing, and chronically high). These five trajectory classes were differentially related to personality traits at age 15 (i.e., extraversion, agreeableness, and emotional stability) and psychosocial functioning at age 20 (i.e., depressive symptoms, self-esteem, anxiety, and perceived stress). These findings underscore the additional value of studying subgroups regarding the development of loneliness.

  7. Orientation-dependent backbone-only residue pair scoring functions for fixed backbone protein design

    Directory of Open Access Journals (Sweden)

    Bordner Andrew J

    2010-04-01

    Full Text Available Abstract Background Empirical scoring functions have proven useful in protein structure modeling. Most such scoring functions depend on protein side chain conformations. However, backbone-only scoring functions do not require computationally intensive structure optimization and so are well suited to protein design, which requires fast score evaluation. Furthermore, scoring functions that account for the distinctive relative position and orientation preferences of residue pairs are expected to be more accurate than those that depend only on the separation distance. Results Residue pair scoring functions for fixed backbone protein design were derived using only backbone geometry. Unlike previous studies that used spherical harmonics to fit 2D angular distributions, Gaussian Mixture Models were used to fit the full 3D (position only and 6D (position and orientation distributions of residue pairs. The performance of the 1D (residue separation only, 3D, and 6D scoring functions were compared by their ability to identify correct threading solutions for a non-redundant benchmark set of protein backbone structures. The threading accuracy was found to steadily increase with increasing dimension, with the 6D scoring function achieving the highest accuracy. Furthermore, the 3D and 6D scoring functions were shown to outperform side chain-dependent empirical potentials from three other studies. Next, two computational methods that take advantage of the speed and pairwise form of these new backbone-only scoring functions were investigated. The first is a procedure that exploits available sequence data by averaging scores over threading solutions for homologs. This was evaluated by applying it to the challenging problem of identifying interacting transmembrane alpha-helices and found to further improve prediction accuracy. The second is a protein design method for determining the optimal sequence for a backbone structure by applying Belief Propagation

    Limited data are available on the characteristics of adolescents with obesity who seek bariatric surgery. Existing data suggest that adolescent surgery candidates have a higher body mass index (BMI) than comparison adolescents with obesity, but the limited findings regarding psychosocial functioning are mixed. This study aimed to compare BMI and psychosocial functioning among adolescent bariatric surgery candidates, outpatient medical-treatment-seeking adolescents with obesity (receiving lifestyle modification), and adolescents in the normal-weight range. All adolescents completed self-report measures of impulsivity, delay discounting, depression, anxiety, stress, eating pathology, family functioning and quality of life, and had their height and weight measured. Adolescent surgical candidates had higher BMIs than both comparison groups. Surgical candidates did not differ from medical-treatment-seeking adolescents with obesity on any measure of psychosocial functioning, but both groups of adolescents with obesity reported greater anxiety and eating pathology and poorer quality of life than normal-weight adolescents. Quality of life no longer differed across groups after controlling for BMI, suggesting that it is highly related to weight status. Adolescents with obesity may experience greater anxiety, eating pathology, and quality of life impairments than their peers in the normal-weight range regardless of whether they are seeking surgery or outpatient medical treatment. Clinical implications and directions for future research are discussed. © 2017 World Obesity Federation.

    Introduction: The use of radical surgical treatments in treating congenital clubfoot is decreasing. Minimally invasive surgical treatment (MIST) is a way of treating congenital clubfoot, which is a kind of compromise between a radical surgical treatment and non-operational one. A few protocols of different authors McKay, Macnicol, Stevens, Meyer, G.W.Simons and Laaveg-Ponseti were used in the evaluation of the results. SCIENTIFIC OBJECTIVE: To determine the importance and role of groups of parameters (clinical, radiographic and functional) in the evaluation of the results in patients treated with the two methods (radical operation and MIST). Subjects and methods: This paper covers children who were treated for structural (idiopathic) form of PEVC. The testing is a prospective study and was conducted in two groups of patients. Group A (radical surgical treatment) – control group, where the total number of subjects was 50, out of which 35 male (70%) and 15 female (30%). The number of feet tested was 88. Group B (minimally invasive surgical treatment–MIST)–experimental group. The total number of subjects was 48, out of which 35 male (73%) and 13 female (27%). The number of feet tested was 84. For the analysis of the results, we used a questionnaire. The total number of parameters was fifteen, clinical, radiographic and functional, five parameters of each. Normal findings or measured value was determined by 0 points. The range of the total score (TS-a- total score range) 0-27 points, and the results were sorted out into the folowing categories: good result (0-5) satisfactory (6-11), poor (12-19) and deformity recrudescence (20-27) points. Results: The proportion of good results at 88 feet in group A was 0,477 as at 84 feet in group B it was significantly higher and came to 0,893. The difference between these proportions is statistically highly significant (t = 5.84, p <0.001). Chi-square test (χ2 = 30.083 df = 1 N = 172, p <0.001) indicated that there is a

    This longitudinal study compares developmental changes in psychosocial functioning during the transition into school of children with and without dyslexia. In addition, it examines the effects of gender and family risk for dyslexia in terms of the associations between dyslexia and psychosocial functioning. Children's psychosocial functioning (social skills, inattention and externalizing and internalizing problems) was evaluated by their parents at ages 4, 6 and 9, and diagnosis for dyslexia was made at age 8 (in grade 2). The findings indicated that children with dyslexia were already rated as having poorer social skills and being more inattentive than were typical readers before their entry into school. Significant interactions of gender and diagnosis of dyslexia emerged for social skills and inattention. The social skills of boys with dyslexia improved after school entry as compared to the level of girls without dyslexia, whereas the social skills of girls with dyslexia did not improve. Boys with dyslexia were rated as showing a high level of inattention both prior to and after school entry, whereas, for girls with dyslexia, inattention ratings increased after school entry, eventually matching the boys' levels.

    In structure-based drug design, scoring functions are widely used for fast evaluation of protein-ligand interactions. They are often applied in combination with molecular docking and de novo design methods. Since the early 1990s, a whole spectrum of protein-ligand interaction scoring functions have been developed. Regardless of their technical difference, scoring functions all need data sets combining protein-ligand complex structures and binding affinity data for parametrization and validation. However, data sets of this kind used to be rather limited in terms of size and quality. On the other hand, standard metrics for evaluating scoring function used to be ambiguous. Scoring functions are often tested in molecular docking or even virtual screening trials, which do not directly reflect the genuine quality of scoring functions. Collectively, these underlying obstacles have impeded the invention of more advanced scoring functions. In this Account, we describe our long-lasting efforts to overcome these obstacles, which involve two related projects. On the first project, we have created the PDBbind database. It is the first database that systematically annotates the protein-ligand complexes in the Protein Data Bank (PDB) with experimental binding data. This database has been updated annually since its first public release in 2004. The latest release (version 2016) provides binding data for 16 179 biomolecular complexes in PDB. Data sets provided by PDBbind have been applied to many computational and statistical studies on protein-ligand interaction and various subjects. In particular, it has become a major data resource for scoring function development. On the second project, we have established the Comparative Assessment of Scoring Functions (CASF) benchmark for scoring function evaluation. Our key idea is to decouple the "scoring" process from the "sampling" process, so scoring functions can be tested in a relatively pure context to reflect their quality. In our

    Training machine learning algorithms with protein-ligand descriptors has recently gained considerable attention to predict binding constants from atomic coordinates. Starting from a series of recent reports stating the advantages of this approach over empirical scoring functions, we could indeed reproduce the claimed superiority of Random Forest and Support Vector Machine-based scoring functions to predict experimental binding constants from protein-ligand X-ray structures of the PDBBind dataset. Strikingly, these scoring functions, trained on simple protein-ligand element-element distance counts, were almost unable to enrich virtual screening hit lists in true actives upon docking experiments of 10 reference DUD-E datasets; this is a a feature that, however, has been verified for an a priori less-accurate empirical scoring function (Surflex-Dock). By systematically varying ligand poses from true X-ray coordinates, we show that the Surflex-Dock scoring function is logically sensitive to the quality of docking poses. Conversely, our machine-learning based scoring functions are totally insensitive to docking poses (up to 10 Å root-mean square deviations) and just describe atomic element counts. This report does not disqualify using machine learning algorithms to design scoring functions. Protein-ligand element-element distance counts should however be used with extreme caution and only applied in a meaningful way. To avoid developing novel but meaningless scoring functions, we propose that two additional benchmarking tests must be systematically done when developing novel scoring functions: (i) sensitivity to docking pose accuracy, and (ii) ability to enrich hit lists in true actives upon structure-based (docking, receptor-ligand pharmacophore) virtual screening of reference datasets.

    The Natsal-SF is a psychometrically validated measure of sexual function for use in community health surveys, derived from 17 questions reflecting three components of sexual function. Scoring requires knowledge of complex statistical modeling and, given the methodological complexities, we assessed the validity of two simplified scoring methods calculated using the factor loadings produced when originally modeling the Natsal-SF items. Method 1 uses these factor loadings to three decimal places, while method 2 assigns whole numbers to each item based on the factor loadings. Scores from these simplified methods are compared to the original score using correlation coefficients, by comparing the distributions and the scores of each method in a linear regression model with key variables. We found scores from the simplified methods both correlate highly with the original score, and the distributions of scores closely match. The simplified methods result in different regression coefficients for gender and relationship context but estimate the coefficients of all other variables similarly to the original method. While the Natsal-SF should ideally be scored using latent variable modeling, the simplified methods perform well so can be used in similar contexts, increasing the utility of the Natsal-SF and enabling future studies to measure sexual function more comprehensively.

    The Maddrey Discriminant Function (mDF) score and the Model for End-Stage Liver Disease (MELD) score are standard prognostic scores for predicting disease severity and mortality in alcoholic hepatitis (AH).This prospective study compared the MELD score and the mDF score as predictors of short-term outcome in AH. The admission MELD score and the mDF score were assessed in 47 patients with a diagnosis of AH in the Himalayan Institute Hospital, Dehradun, India and the concordance (C) statistics of the two scores for 28-day mortality were determined and compared. Both the MELD score and the mDF score on day 1 were significantly higher in non-survivors than in survivors (P = 0.0001 each). The C-statistic for 28-day mortality for the MELD score was 0.91 (P mDF score 0.90 (P  19 (sensitivity 91.6% and specificity 85.7%) corresponded to the mDF score of > 52.8 (sensitivity 91.6% and specificity 82.8%). Both the MELD score and the mDF score at admission were strong and equally good predictors of 28-day mortality in patients with AH, but the optimal mDF score corresponding to optimal MELD score was higher than the conventional one. Thus, MELD score may be used as an alternative to mDF score for predicting short-term mortality in AH with an advantage. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Automated docking is one of the most important tools for structure-based drug design that allows prediction of ligand binding poses and also provides an estimate of how well small molecules fit in the binding site of a protein. A new scoring function based on AutoDock and AutoDock Vina has been introduced. The new hybrid scoring function is a linear combination of the two scoring function components derived from a multiple linear regression fitting procedure. The scoring function was built on a training set of 2412 protein-ligand complexes from pdbbind database (www.pdbbind.org.cn, version 2012). A test set of 313 complexes that appeared in the 2013 version was used for validation purposes. The new hybrid scoring function performed better than the original functions, both on training and test sets of protein-ligand complexes, as measured by the non-parametric Pearson correlation coefficient, R, mean absolute error (MAE), and root-mean-square error (RMSE) between the experimental binding affinities and the docking scores. The function also gave one of the best results among more than 20 scoring functions tested on the core set of the pdbbind database. The new AutoDock hybrid scoring function will be implemented in modified version of AutoDock. © 2015 John Wiley & Sons A/S.

    2014-04-01

    This mixed-methods, quasi-experimental pilot study examined whether the Nintendo Wii Sports (NWS) active video game (exergame) system could significantly improve the functional ability, physical activity levels, and quality of life of 34 older adults (4 men and 30 women, 83 ± 8 yr) living in 2 residential aged-care (RAC) centers. Change score analyses indicated the intervention group had significantly greater increases in bicep curl muscular endurance, physical activity levels, and psychological quality of life than the control group (p < .05). Analysis of the quotes underlying the 3 themes (feeling silly, feeling good; having fun; and something to look forward to) suggested that intervention group participants developed a sense of empowerment and achievement after some initial reluctance and anxiousness. They felt that the games were fun and provided an avenue for greater socialization. These results add some further support to the utilization of NWS exergames in the RAC context.

    Understanding the basic neural processes that underlie complex higher order cognitive operations and psychosocial functioning is a fundamental goal of cognitive neuroscience. Event-related potentials allow investigators to probe the earliest stages of information processing. Mismatch negativity (MMN) and P3a are auditory event-related potential components that reflect automatic sensory discrimination. The aim of the present study was to determine if MMN and P3a are associated with higher order cognitive operations and psychosocial functioning in clinically normal healthy subjects. Twenty adults were assessed using standardized clinical, cognitive, and psychosocial functional instruments. All individuals were within the normal range on cognitive tests and functional ratings. Participants were also tested on a duration-deviant MMN/P3a paradigm (50-msec standard tones, p = .90; 100-msec deviant tones, p = .10; stimulus onset asynchrony [SOA] = 505 msec). Across fronto-central electrode regions, significant correlations were observed between psychosocial functioning and MMN (r = -.62, p sensory information processing are associated with higher order cognitive abilities and psychosocial functioning in normal subjects. Efficiency at elementary levels of information processing may underlie the successful encoding, retrieval, and discrimination of task-relevant information, which, in turn, facilitates the iterative and responsive processing necessary for adaptive cognitive and social functioning.

  7. Improving molecular docking through eHiTS' tunable scoring function

    Ravitz, Orr; Zsoldos, Zsolt; Simon, Aniko

    2011-11-01

    We present three complementary approaches for score-tuning that improve docking performance in pose prediction, virtual screening and binding affinity assessment. The methodology utilizes experimental data to customize the scoring function for the system of interest considering the specific docking scenario. The tuning approach, which has been implemented as an automated utility in eHiTS, is introduced as a solution to one of the conundrums of the molecular docking paradigm, namely, the lack of a universally well performing scoring function. The accuracy of scoring functions has been shown to be generally system-dependent, and particularly lacking for binding energy and bio-activity predictions. In the proposed approach, pose and energy predictions are enhanced by adjusting the relative weights of the eHiTS energy terms to improve score-RMSD or score-affinity correlations. In a virtual screening context ligand-based similarity is used to rescale the docking score such that better enrichment factors are achieved. We discuss the algorithmic details of the methods, and demonstrate the effects of score tuning on a variety of targets, including CDK2, BACE1 and neuraminidase, as well as on the popular benchmarks—the Directory of Useful Decoys and the PDBBind database.

    This study examined religious identity as a mediator and moderator between religious socialization by parents, peers, and religious mentors and psychosocial functioning (i.e., social competence, internalizing and externalizing behavior problems) among 155 Korean American adolescents. Religious socialization by parents and peers were positively associated with adolescents' religious identity and social competence. Religious identity fully mediated the relationship between religious socialization by parents and social competence, and partially mediated the relationship between religious socialization by peers and social competence. A competing model with religious identity as a moderator found adolescents with low religious identity showed significantly more externalizing behavior problems when they received more religious socialization from parents.

    On the basis of the multidimensional model of the caregiving process, this study aimed (a) to compare the levels of quality of life (QoL) and psychological problems of children with short stature and the levels of caregiving stress and QoL of their parents, between diagnostic, treatment, and current height deviation groups, and (b) to examine the direct and indirect links, via caregiving stress, between children's psychosocial functioning and their parents' QoL. The sample was collected in 5 European countries and comprised 238 dyads of 8- to 18-year-old children and adolescents with a clinical diagnosis of growth hormone deficiency or idiopathic short stature and one of their parents. The children completed self-report measures of height-related QoL (Quality of Life in Short Stature Youth Core Module) and psychological problems (Strengths and Difficulties Questionnaire); the parents reported on their own QoL (EUROHIS-QOL-8 Index) and caregiving stress (Quality of Life in Short Stature Youth Effects on Parents subscale). Children who were treated and who achieved normal height reported better QoL compared to those untreated and with current short stature. Parents of children with idiopathic short stature and current short stature presented greater caregiving stress than parents of children with growth hormone deficiency and achieved normal height. Children's better psychosocial functioning was indirectly associated with parents' better QoL, via less caregiving stress, and these links were invariant across diagnoses, treatment status, and current height deviation. These results suggest that, along with growth hormone treatments, multidisciplinary interventions in paediatric endocrinology should be family-centred, by targeting both the children's psychosocial functioning and the parents' stress, in order to improve individual and family adaptation. Key Practitioner Message Height-related quality of life impairments and more internalizing problems in children and

    The Functional Assessment for Burns (FAB) score is established as an objective measure of physical function that predicts discharge outcome in adult patients with major burn. However, its validity in patients with minor and moderate burn is unknown. This is a multi-centre evaluation of the predictive validity of the FAB score for discharge outcome in adult inpatients with minor and moderate burns. FAB assessments were undertaken within 48 h of admission to (FAB 1), and within 48 h of discharge (FAB 2) from burn wards in 115 patients. Median age was 45 years and median burn size 4%. There were significant improvements in the patients' FAB scores (pburns.

    In the present study, we focus on the concept of adolescent autonomy and its relation with psychosocial functioning. Specifically, we aim to differentiate between 2 prevailing conceptualizations of autonomy, that is, (a) autonomy defined as independence versus dependence and (b) autonomy defined as self-endorsed versus controlled functioning. A 2nd goal is to examine the relative contribution of each autonomy operationalization in the prediction of adolescents' adjustment (i.e., well-being, problem behavior, and intimacy). Data were gathered in a sample of 707 Belgian adolescents. Using a newly developed questionnaire, we assessed both the degree of independent decision making per se and the self-endorsed versus controlled motives underlying both independent and dependent decision making. The degree of independent decision making could clearly be differentiated from the underlying motives for doing so. Moreover, independent decision making as such showed unique associations with more problem behavior. Further, as expected, self-endorsed motives for both independent and dependent decision making generally related to an adaptive pattern of psychosocial functioning, and controlled motives were associated with maladjustment. The discussion focuses on the difference between the 2 perspectives on autonomy and on the different meaning of the motives underlying independent, relative to dependent, decision making.

    Human depression, for which chronic psychosocial stress is a major risk factor, is characterized by consistent alterations in neurocircuitry. For example, there is increased functional connectivity (FC) within and between regions comprising the default mode network (DMN) including prefrontal cortex and cingulate cortex. Alterations in network FC are associated with specific aspects of psychopathology. In mice, chronic psychosocial stress (CPS) leads to depression-relevant behavior, including increased fear learning, learned helplessness, fatigue and decreased motivation for reward. Using multimodal in vivo magnetic resonance imaging (MRI) and spectroscopy (MRS), we investigated CPS effects on function and structure in the mouse brain under light anesthesia. Mice underwent a baseline MRI/MRS session, followed by 15-day CPS (n=26) or control handling (n=27), and a post-treatment MRI/MRS session. In BOLD fMRI, relative to controls, CPS mice exhibited robust, reproducible increases in FC within 8 of 9 identified cortical networks, including the prefrontal and cingulate cortices that contribute to the "mouse DMN". CPS mice exhibited increases in between-network FC, including amygdala - prefrontal cortex and amygdala - cingulate cortex. MRS identified metabolic alterations in CPS mice as increased inositol levels in amygdala and increased glycerophosphorylcholine levels in prefrontal cortex. Diffusion-weighted MRI detected increased fractional anisotropic values in the cingulum. This study demonstrates that chronic psychosocial stress induces FC states in the mouse brain analogous to those observed in depression, as well as cerebral metabolism and white matter pathway alterations that contribute to understanding of pathological processes. It also demonstrates the importance of brain imaging to the establishment of valid animal models in translational psychiatry.

    Objective: To compare the high resolution CT (HRCT) scores of the Bhalla system with pulmonary function tests and radiographic and clinical points of the Shwachman-Kulczycki clinical scoring system. Methods: HRCT of the chest was obtained in 40 children to assess the role of HRCT in evaluating bronchopulmonary pathology in children with cystic fibrosis (CF). The HRCT severity scores of the Bhalla system were compared with chest radiographic and clinical points of the Shwachman-Kulczycki scoring system and pulmonary function tests. Only 14 of the patients older than 6 years cooperated with spirometry. Results: HRCT scores correlated well with radiographic points (r=0.80, P<0.0001) and clinical points (r=0.67, P<0.0001) of the Shwachman-Kulczycki system, FVC (r=0.71 P=0.004) and FEV{sub 1} (r=0.66, P=0.01). Although radiographic points correlated significantly with FVC (r=0.61, P=0.02) and FEV{sub 1} (r=0.56, P=0.04), HRCT provides a more precise scoring than the chest X-ray. Conclusion: The HRCT scoring system may provide a sensitive method of monitoring pulmonary disease status and may replace the radiographic scoring in the Shwachman-Kulczycki system. It may be helpful especially in follow-up of small children too young to cooperate with spirometry.

    Full Text Available BACKGROUND: We explore the association between bone T-scores, used in osteoporosis diagnosis, and functional status since we hypothesized that bone health can impact elderly functional status and indirectly independence. METHODS: In a cross-sectional study (2005-2006 on community dwelling elderly (> = 75 years from Herne, Germany we measured bone T-scores with Dual-energy X-ray Absorptiometry, and functional status indexed by five geriatric tests: activities of daily living, instrumental activities of daily living, test of dementia, geriatric depression score and the timed-up-and-go test, and two pooled indexes: raw and standardized. Generalized linear regression was used to determine the relationship between T-scores and functional status. RESULTS: From 3243 addresses, only 632 (19% completed a clinical visit, of which only 440 (male:female, 243:197 could be included in analysis. T-scores (-0.99, 95% confidence interval [CI], -1.1-0.9 predicted activities of daily living (95.3 CI, 94.5-96.2, instrumental activities of daily living (7.3 CI, 94.5-96.2, and timed-up-and-go test (10.7 CI, 10.0-11.3 (P < = 0.05. Pooled data showed that a unit improvement in T-score improved standardized pooled functional status (15 CI, 14.7-15.3 by 0.41 and the raw (99.4 CI, 97.8-101.0 by 2.27 units. These results were limited due to pooling of different scoring directions, selection bias, and a need to follow-up with evidence testing. CONCLUSIONS: T-scores associated with lower functional status in community-dwelling elderly. Regular screening of osteoporosis as a preventive strategy might help maintain life quality with aging.

  17. Scoring protein relationships in functional interaction networks predicted from sequence data.

    Gaston K Mazandu

    Full Text Available UNLABELLED: The abundance of diverse biological data from various sources constitutes a rich source of knowledge, which has the power to advance our understanding of organisms. This requires computational methods in order to integrate and exploit these data effectively and elucidate local and genome wide functional connections between protein pairs, thus enabling functional inferences for uncharacterized proteins. These biological data are primarily in the form of sequences, which determine functions, although functional properties of a protein can often be predicted from just the domains it contains. Thus, protein sequences and domains can be used to predict protein pair-wise functional relationships, and thus contribute to the function prediction process of uncharacterized proteins in order to ensure that knowledge is gained from sequencing efforts. In this work, we introduce information-theoretic based approaches to score protein-protein functional interaction pairs predicted from protein sequence similarity and conserved protein signature matches. The proposed schemes are effective for data-driven scoring of connections between protein pairs. We applied these schemes to the Mycobacterium tuberculosis proteome to produce a homology-based functional network of the organism with a high confidence and coverage. We use the network for predicting functions of uncharacterised proteins. AVAILABILITY: Protein pair-wise functional relationship scores for Mycobacterium tuberculosis strain CDC1551 sequence data and python scripts to compute these scores are available at http://web.cbio.uct.ac.za/~gmazandu/scoringschemes.

    In the treatment of schizophrenia, the domain of psychosocial functioning is an important aspect of therapeutic success that should be considered in addition to the reduction of psychopathology. Valid and standardised measures are necessary for diagnostics and the assessment of patients" personal, social and professional functioning. The German version of the Personal and Social Performance (PSP) Scale (with its four subdimensions: "socially useful activities, work and study included", "personal and social relationships", "self-care" and "disturbing and aggressive behaviour") was administered to patients with schizophrenia in previous studies. These data demonstrated this scale to be a reliable, valid and efficient tool for measuring psychosocial functioning in schizophrenia. Thus, it is argued that, for everyday clinical practice, the PSP Scale is useful for the assessment of psychosocial functioning in schizophrenia during short, medium and long-term treatment courses.

    Little is known about the sexual well-being of male Veteran cancer survivors, or the relationship of sexual concerns to psychosocial adaptation postcancer. This study examined the association between sexual self-esteem and psychosocial concerns in male Veteran cancer survivors. Forty-one male survivors were recruited from a Veterans Affairs (VA) hospital to participate in a pilot study addressing cancer survivorship care for Veterans. Sixty- to 90-minute interviews were conducted, assessing sociodemographic, medical, stress/burden (cancer-related posttraumatic stress disorder [PTSD], depression), and resource (social support, post-traumatic growth) variables. Twenty-one (51.2%) Veteran cancer survivors reported lowered sexual self-esteem as a result of cancer, which corresponded to significantly higher levels of depression and cancer-related PTSD. The lowered sexual self-esteem group also indicated significantly lower social support. Veteran cancer survivors with lowered sexual self-esteem tend to have higher levels of stress and lower levels of resources, putting them at risk for lowered quality of life. This increased risk highlights the importance of addressing sexual well-being in the survivorship care of Veterans.

    Although adolescence is characterized by hormonal changes and increased disinhibited behaviors, explanations for these developmental changes that include personality and environmental factors have not been fully elucidated. We examined the interactions between psychosocial stress and the traits of negative emotionality and constraint on impulsive and risk-taking behaviors as well as salivary cortisol reactivity in 88 adolescents. In terms of behavioral outcomes, analyses revealed that negative emotionality and constraint were protective of impulsivity and risk taking, respectively, for adolescents in the no-stress condition; personality did not relate to either behavior in the stress condition. Low-constraint adolescents in the stress condition engaged in less risk taking than low-constraint adolescents in the no-stress condition, whereas there was no effect of stress group for high-constraint adolescents. In terms of cortisol reactivity, analyses revealed that low-constraint adolescents in the stress condition exhibited greater cortisol reactivity compared to high-constraint adolescents, which suggests that low-constraint adolescents mobilize greater resources (e.g., increased cognitive control, heightened attention to threat) in stressful situations relative to nonstressful ones. These results demonstrate that two facets of disinhibition and cortisol reactivity are differentially affected by psychosocial stress and personality (and their interactions) in adolescents.

  1. Efficacy of PROMIS Pain Interference and Likert Pain Scores to Assess Physical Function.

    St John, Matthew J; Mitten, David; Hammert, Warren C

    2017-09-01

    The Patient Reported Outcome Measurement Information System (PROMIS), developed by the National Institutes of Health, utilizes a health domain related to Pain Interference (PI). We evaluated this domain and its association with physical function (as determined by PROMIS Physical Function [PF]), administered as a computer adaptive test (CAT), and secondarily its association to a numerical 0 to 10 pain score. Our null hypothesis was that PI, as measured by CAT, has no correlation to PF and thus, there is no difference between comparisons of numerical pain scores and PROMIS PF. Adult patients presenting to an upper extremity clinic from February to December 2015 completed PROMIS PF, PI, and numerical 0 to 10 pain score questionnaires. The PROMIS modules were completed electronically in their computer adaptive form. Mean population scoring on each module is defined at 50. Patients were also asked to rate their pain on a 0 to 10 scale. These data were collected as routine clinical care and were extracted from the electronic health record for cross-sectional evaluation. Bivariate Pearson correlation analysis defined the association between the PROMIS modules and the numerical pain scores. Correlations between PF and PI were compared with correlations between PF and pain scores. We recorded data from patients' 10,574 first, 5,210 second, 2,633 third, 1,382 fourth, and 722 fifth visits. The PROMIS PI was negatively correlated to the PROMIS PF. Numerical pain scores were also negatively correlated to PROMIS PF. Numerical pain scores were less correlated than PROMIS PI through time relative to PF. Both PROMIS PI and numerical pain scores had significant correlations with PF for each office visit. The PI had a larger correlation to PF than did numerical pain scores. The PI and numerical pain scale scores are also correlated. Patient-reported pain using a 0 to 10 pain score can be a predictor of patients' level of function, and although pain score does not replace other

    DEFF Research Database (Denmark)

    Guns, Raf; Lioma, Christina; Larsen, Birger

    2012-01-01

    One of the best known measures of information retrieval (IR) performance is the F-score, the harmonic mean of precision and recall. In this article we show that the curve of the F-score as a function of the number of retrieved items is always of the same shape: a fast concave increase to a maximum......, followed by a slow decrease. In other words, there exists a single maximum, referred to as the tipping point, where the retrieval situation is 'ideal' in terms of the F-score. The tipping point thus indicates the optimal number of items to be retrieved, with more or less items resulting in a lower F...

  4. A knowledge-guided strategy for improving the accuracy of scoring functions in binding affinity prediction

    Directory of Open Access Journals (Sweden)

    Wang Renxiao

    2010-04-01

    Full Text Available Abstract Background Current scoring functions are not very successful in protein-ligand binding affinity prediction albeit their popularity in structure-based drug designs. Here, we propose a general knowledge-guided scoring (KGS strategy to tackle this problem. Our KGS strategy computes the binding constant of a given protein-ligand complex based on the known binding constant of an appropriate reference complex. A good training set that includes a sufficient number of protein-ligand complexes with known binding data needs to be supplied for finding the reference complex. The reference complex is required to share a similar pattern of key protein-ligand interactions to that of the complex of interest. Thus, some uncertain factors in protein-ligand binding may cancel out, resulting in a more accurate prediction of absolute binding constants. Results In our study, an automatic algorithm was developed for summarizing key protein-ligand interactions as a pharmacophore model and identifying the reference complex with a maximal similarity to the query complex. Our KGS strategy was evaluated in combination with two scoring functions (X-Score and PLP on three test sets, containing 112 HIV protease complexes, 44 carbonic anhydrase complexes, and 73 trypsin complexes, respectively. Our results obtained on crystal structures as well as computer-generated docking poses indicated that application of the KGS strategy produced more accurate predictions especially when X-Score or PLP alone did not perform well. Conclusions Compared to other targeted scoring functions, our KGS strategy does not require any re-parameterization or modification on current scoring methods, and its application is not tied to certain systems. The effectiveness of our KGS strategy is in theory proportional to the ever-increasing knowledge of experimental protein-ligand binding data. Our KGS strategy may serve as a more practical remedy for current scoring functions to improve their

    Increasingly, empirical support demonstrates that the built environment may affect the physical and psychosocial well-being of patients, their families, and hospital staff (Beauchemin & Hays, 1996; Rubin, Owens, & Golden, 1998; Sherman, Varni, Ulrich, & Malcarne, 2005; Ulrich, 1991; Varni et al., 2004; Whitehouse et al., 2001). Investigators posit two mechanisms through which the built environment can impact patients: indirectly, by enhancing the quality of care and helping a patient feel more relaxed; and/or directly, by altering the physiological recovery process (Malcolm, 1992). Several literature reviews have been published on the relationship between the hospital built environment and patient outcomes (Joseph, Keller, & Kronick, 2008; Rubin et al., 1998; Sherman, Shepley, & Varni, 2005; Ulrich, Quan, Zimring, Joseph, & Choudhary, 2004). In their 1998 review, Rubin et al. found studies linking environment with a number of health and satisfaction outcomes but little research that had been conducted in a scientifically valid manner. Ulrich et al.'s 2004 review of the role of the physical environment in hospital design identified a number of more rigorously conducted studies, focusing mainly on adult environments and on issues of medical safety and hospital-acquired infection rates. Their conclusions linked environmental features such as noise to an increase in perceived stress and physiological arousal; exposure to natural light to reductions in depression, length of hospital stay, and pain medications and to improved sleep; and hospital gardens to improved physical and psychosocial functioning (Ulrich et al., 2004).

    2016-02-01

    Osteoarthritis (OA) is a highly prevalent and disabling chronic condition. Because physical activity is a key component in OA management, effective exercise interventions are needed. Yoga is an increasingly popular multimodal mind-body exercise that aims to promote flexibility, strength, endurance, and balance. Its gentle approach is potentially a safe and effective exercise option for managing OA. The purpose of this focused review is to examine the effects of yoga on OA symptoms and physical and psychosocial outcomes. A comprehensive search was conducted using seven electronic databases. Twelve reports met inclusion criteria involving a total of 589 participants with OA-related symptoms. A variety of types, frequencies, and durations of yoga interventions were reported; Hatha and Iyengar yoga were the most commonly used types. Frequency of intervention ranged from once a week to 6 days a week. Duration of the interventions ranged from 45 to 90 mins per session for 6 to 12 wks. Yoga intervention resulted in reductions in pain, stiffness, and swelling, but results on physical function and psychosocial well-being were inconclusive because of a variety of outcome measures being used.

    Although families of children with cancer and other serious medical conditions have documented psychosocial needs, the systematic identification of needs and delivery of evidence-based care remain challenges. Screening for multifaceted family psychosocial risk is a means by which psychosocial treatment needs for pediatric patients and their families can be identified in an effective and inclusive manner. The Pediatric Psychosocial Preventative Health Model (PPPHM) is a model that can guide systematic assessment of family psychosocial risk. The Psychosocial Assessment Tool (PAT) is a brief parent report screener of psychosocial risk based on the PPPHM that can be used for families of infants through adolescents. The PPPHM and the PAT are described in this paper, along with a summary of data supporting systematic risk assessment. The PPPHM outlines three tiers of family psychosocial risk - Universal (low), Targeted (medium), and Clinical (high). The PAT is a validated measure of psychosocial risk. Scores on the PAT, derived from multiple sites and disease conditions, map on to the PPPHM with indications that one-half to two-thirds of families score at the Universal level of risk based on the PAT. The PAT is a unique screener of psychosocial risk, both in terms of its breadth and underlying model (PPPHM), and its length and format. As an example of a means by which families can be screened early in the treatment process, PAT scores and corresponding PPPHM levels can provide direction for the delivery of evidence-based psychosocial care.

    2017-02-01

    Full Text Available This study had two main objectives: (1 to determine if differences in Functional Movement Screen (FMS scores exist between two levels of competition; and (2 to analyze the association between FMS individual and overall scores and physical performance variables of lower-limb power (jumps, repeated sprint ability and shot speed. Twenty-two Under 16 (U16 and twenty-six Under 19 (U19 national competitive soccer players participated in this study. All participants were evaluated according to anthropometrics, FMS, jump performance, instep kick speed and anaerobic performance. There were no significant differences in the individual FMS scores between competitive levels. There were significant negative correlations between hurdle step (right and Running-based Anaerobic Sprint Test (RAST power average ( ρ = −0.293; p = 0.043 and RAST fatigue index (RAST FatIndex ( ρ = −0.340; p = 0.018. The hurdle step (left had a significant negative correlation to squat jump (SJ ( ρ = −0.369; p = 0.012. Rotary stability had a significant negative correlation to RAST fatigue index (Right: ρ = −0.311; p = 0.032. Left: ρ = −0.400; p = 0.005. The results suggest that individual FMS scores may be better discriminants of performance than FMS total score and established minimal association between FMS scores and physical variables. Based on that, FMS may be suitable for the purposes of determining physical function but not for discriminating physical performance.

  9. Use of Functional Ambulation Performance Score as measurement of gait ability: Review

    Directory of Open Access Journals (Sweden)

    Arnaud Gouelle, PhD

    2014-09-01

    Full Text Available Gait analysis systems are widely used for the assessment of gait disabilities and provide more accurate and detailed information than clinical tests. Scores and indexes have been proposed to summarize the large volume of data produced, each emphasizing different aspects of gait. Based on specific spatiotemporal gait parameters, the Functional Ambulation Performance Score (FAPS quantifies gait at a self-selected speed. Integrated within electronic walkways, the FAPS is commonly used for clinical evaluations and has been used in an increasing number of publications over the past few years. However, its use is sometimes distorted by misunderstandings of its composition and calculation, practical and/or conceptual limits, and even the meaning of the score. This technical report reviews the use of the FAPS for the evaluation of gait based on peer-reviewed articles and clinical experience and addresses important issues that must be considered for an optimal unbiased understanding and analysis of the score.

  10. AIScore chemically diverse empirical scoring function employing quantum chemical binding energies of hydrogen-bonded complexes.

    2008-07-01

    In this work we report on a novel scoring function that is based on the LUDI model and focuses on the prediction of binding affinities. AIScore extends the original FlexX scoring function using a chemically diverse set of hydrogen-bonded interactions derived from extensive quantum chemical ab initio calculations. Furthermore, we introduce an algorithmic extension for the treatment of multifurcated hydrogen bonds (XFurcate). Charged and resonance-assisted hydrogen bond energies and hydrophobic interactions as well as a scaling factor for implicit solvation were fitted to experimental data. To this end, we assembled a set of 101 protein-ligand complexes with known experimental binding affinities. Tightly bound water molecules in the active site were considered to be an integral part of the binding pocket. Compared to the original FlexX scoring function, AIScore significantly improves the prediction of the binding free energies of the complexes in their native crystal structures. In combination with XFurcate, AIScore yields a Pearson correlation coefficient of R P = 0.87 on the training set. In a validation run on the PDBbind test set we achieved an R P value of 0.46 for 799 attractively scored complexes, compared to a value of R P = 0.17 and 739 bound complexes obtained with the FlexX original scoring function. The redocking capability of AIScore, on the other hand, does not fully reach the good performance of the original FlexX scoring function. This finding suggests that AIScore should rather be used for postscoring in combination with the standard FlexX incremental ligand construction scheme.

  11. NNScore 2.0: A Neural-Network Receptor–Ligand Scoring Function

    Science.gov (United States)

    2011-01-01

    NNScore is a neural-network-based scoring function designed to aid the computational identification of small-molecule ligands. While the test cases included in the original NNScore article demonstrated the utility of the program, the application examples were limited. The purpose of the current work is to further confirm that neural-network scoring functions are effective, even when compared to the scoring functions of state-of-the-art docking programs, such as AutoDock, the most commonly cited program, and AutoDock Vina, thought to be two orders of magnitude faster. Aside from providing additional validation of the original NNScore function, we here present a second neural-network scoring function, NNScore 2.0. NNScore 2.0 considers many more binding characteristics when predicting affinity than does the original NNScore. The network output of NNScore 2.0 also differs from that of NNScore 1.0; rather than a binary classification of ligand potency, NNScore 2.0 provides a single estimate of the pKd. To facilitate use, NNScore 2.0 has been implemented as an open-source python script. A copy can be obtained from http://www.nbcr.net/software/nnscore/. PMID:22017367

    Chronic benzodiazepine use is common in patients with mental illness and is associated with cognitive impairment. It is unclear whether benzodiazepine-induced cognitive impairment is reversible. Amelioration of cognitive dysfunction may be facilitated during benzodiazepine tapering by add......-on melatonin due to its anti-inflammatory and neuroprotective properties. We examined how melatonin and benzodiazepine withdrawal affect cognition, subjective well-being, and psychosocial functioning. Eighty patients with schizophrenia or bipolar disorder were randomized to add-on treatment once daily...... with either prolonged-release melatonin or placebo in a 24-week, double-blind clinical trial. All participants gradually tapered usual benzodiazepine dosage in a closely monitored treatment setting. We used the Brief Assessment of Cognition in Schizophrenia (BACS) to assess neurocognitive performance...

    The iScore is a prediction tool originally developed to estimate the risk of death after hospitalization for an acute ischemic stroke. Our objective was to determine whether the iScore could also predict poor functional outcomes. We applied the iScore to patients presenting with an acute ischemic stroke at multiple hospitals in Ontario, Canada, between 2003 and 2008, who had been identified from the Registry of the Canadian Stroke Network regional stroke center database (n=3818) and from an external data set, the Registry of the Canadian Stroke Network Ontario Stroke Audit (n=4635). Patients were excluded if they were included in the sample used to develop and validate the initial iScore. Poor functional outcomes were defined as: (1) death at 30 days or disability at discharge, in which disability was defined as having a modified Rankin Scale 3 to 5; and (2) death at 30 days or institutionalization at discharge. The prevalence of poor functional outcomes in the Registry of the Canadian Stroke Network and the Ontario Stroke Audit, respectively, were 55.7% and 44.1% for death at 30 days or disability at discharge and 16.9% and 16.2%, respectively, for death at 30 days or institutionalization at discharge. The iScore stratified the risk of poor outcomes in low- and high-risk individuals. Observed versus predicted outcomes showed high correlations: 0.988 and 0.940 for mortality or disability and 0.985 and 0.993 for mortality or institutionalization in the Registry of the Canadian Stroke Network and Ontario Stroke Audit cohorts. The iScore can be used to estimate the risk of death or a poor functional outcome after an acute ischemic stroke.

    Functional Movement Screen (FMS) have been used to assess the movement patterns in daily sports practice. Some associations between FMS scores and physical variables have been found in some sports. Nevertheless, no study was conducted in surf. Eighteen surf athletes (11 male) participated in the study (18.3 ± 6.3 y; 60.0 ± 9.6 kg; 168.6 ± 8.1 cm). All participants completed anthropometrics, Knee to Wall test, Functional Movement Screen, Isometric Knee Extension, Handgrip, Squat and Countermovement Jump. Based on that, this study investigated: 1) the variance of FMS scores between gender; 2) the association between FMS scores and physical variables of strength of upper and lower limbs, power of lower limbs and anthropometric variables; and 3) which FMS scores best explain the physical performance variables. The analysis of comparison between gender of each item of FMS showed significant statistical differences only in Trunk Stability Push-Up (p = 0.01, ES=0.141). Kendall's Tau b correlation test between FMS scores and physical variables, revealed significant associations. After performed the stepwise multiple linear regression FMS Deep Squat and Trunk Stability Push-Up explains 57% of Knee to Wall test - right side and the model is statistically significant (F(2. 15) = 13.097; p-value = 0.001). In Squat Jump (height) the results show that FMS Trunk Stability Push-Up explains 50.3% of this dimension and the model is statistically significant (F(1. 16) = 18.182; p-value = 0.001). FMS individual scores seems to better explain physical variables than total score. Only Trunk Stability Push-Up test seems to be a reliable indicator to predict physical performance in surf athletes.

    Psychological comorbidity is common in bariatric surgery candidates. Many multidisciplinary teams incorporate psychometric testing to screen for psychological factors that, if left unattended, may negatively impact surgical results. Here, we report descriptive findings and empirical correlates of Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) scales among of bariatric surgery candidates undergoing a pre-surgical psychological evaluation. The sample consisted of male (n = 324) and female (n = 658) patients seeking bariatric surgery who were administered the MMPI-2-RF at their psychological evaluation. Psychosocial and medical variables were retrospectively coded from the patients' medical records. These criteria included history/current mental health diagnoses and treatments, maladaptive eating behaviors/diagnoses, past/current substance use, abuse history, sleep apnea, and denial of surgery. Descriptive analyses demonstrated similar findings for male and female candidates and replicated previous reports. MMPI-2-RF scales measuring emotional dysfunction were associated with maladaptive eating patterns, a history of Major Depressive Disorder, and previous suicide attempts. Scale scores measuring behavioral dysfunction were associated with current/past substance use and previous physical abuse. MMPI-2-RF scale scores measuring somatic problems were associated with a higher BMI at the time of surgery, sleep apnea diagnosis/adherence, physical/sexual abuse history, active mood disorder, previous mental health diagnoses, and maladaptive eating patterns. The MMPI-2-RF can aid in identifying a broad range of psychological comorbidity among bariatric surgery candidates. When used in conjunction with a pre-surgical psychological interview, it can aid in the assessment of psychological factors relevant to pre-surgical psychological assessment of bariatric surgery candidates.

    With the increasing focus on reducing hospital readmissions in the United States, numerous readmissions risk prediction models have been proposed, mostly developed through analyses of structured data fields in electronic medical records and administrative databases. Three areas that may have an impact on readmission but are poorly captured using structured data sources are patients' physical function, cognitive status, and psychosocial environment and support. The objective of the study was to build a discriminative model using information germane to these 3 areas to identify hospitalized patients' risk for 30-day all cause readmissions. We conducted clinician focus groups to identify language used in the clinical record regarding these 3 areas. We then created a dataset including 30,000 inpatients, 10,000 from each of 3 hospitals, and searched those records for the focus group-derived language using natural language processing. A 30-day readmission prediction model was developed on 75% of the dataset and validated on the other 25% and also on hospital specific subsets. Focus group language was aggregated into 35 variables. The final model had 16 variables, a validated C-statistic of 0.74, and was well calibrated. Subset validation of the model by hospital yielded C-statistics of 0.70-0.75. Deriving a 30-day readmission risk prediction model through identification of physical, cognitive, and psychosocial issues using natural language processing yielded a model that performs similarly to the better performing models previously published with the added advantage of being based on clinically relevant factors and also automated and scalable. Because of the clinical relevance of the variables in the model, future research may be able to test if targeting interventions to identified risks results in reductions in readmissions.

    The alternative dimensional model of personality disorder (PD) in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5; American Psychiatric Association, 2013), Section III, has two main criteria: impairment in personality functioning and one or more pathological personality traits. The former is defined as disturbances in self-functioning (viz., identity, self-direction), and/or interpersonal functioning (viz., empathy, intimacy). Distinguishing personality functioning and traits is important conceptually, because simply having extreme traits is not necessarily pathological. However, adding personality functioning to PD diagnosis represents an empirical challenge, because the constructs overlap conceptually. Further, there is debate regarding whether diagnosis of mental disorder requires either distress or disability, concepts that also overlap with maladaptive-range personality traits and personality dysfunction. We investigated interrelations among these constructs using multiple self-report measures of each domain in a mixed community-patient sample (N = 402). We examined the structures of functioning (psychosocial disability and personality) and personality traits, first independently, then jointly. The disability/functioning measures yielded the 3 dimensions we have found previously (Ro & Clark, 2013). Trait measures had a hierarchical structure which, at the 5-factor level, reflected neuroticism/negative affectivity (N/NA), (low) sociability, disinhibition, (dis)agreeableness, and rigid goal engagement. When all measures were cofactored, a hierarchical structure again emerged which, at the 5-factor level, included (a) internalizing (N/NA and self-pathology vs. quality-of-life/satisfaction); (b) externalizing (social/interpersonal dysfunction, low sociability, and disagreeableness); (c) disinhibition; (d) poor basic functioning; and (e) rigid goal engagement. Results are discussed in terms of developing an integrated PD diagnostic

    To investigate the correlation of the vestibular evoked myogenic potential (VEMP) score with Timed 25-Foot Walk (T25FW), 9-Hole Peg Test (9HPT), Paced Auditory Serial Addition Test (PASAT) and EDSS in patients with multiple sclerosis (MS). This prospective, cross sectional study included 52 patients with clinically isolated syndrome (CIS). Cervical VEMP (cVEMP) and ocular VEMP (oVEMP), analyzed in the form of the cVEMP, oVEMP and VEMP scores, T25FW, 9HPT, PASAT and Expanded Disability Status Scale (EDSS) were performed. The only predictor of walking impairment in this study was general disability as measured by the EDSS, after controlling for age, gender, PASAT and EDSS the effect of VEMP score was non-significant (p=0.419). 9HPT of the dominant hand did not correlate with the oVEMP score (rs=0.258, p=0.065), however after controlling for age, gender, PASAT and EDSS, the effect of the oVEMP score on 9HPT of the dominant hand was statistically significant (p=0.017). After controlling for age, gender and oVEMP score, the effect of the PASAT on 9HPT variable for the non-dominant hand was statistically significant (p=0.001). We found possible effects of brainstem dysfunction on walking impairment, however they were not seen after correction for EDSS and cognitive dysfunction. On the other hand, dominant hand function seems to be influenced by upper brainstem dysfunction measured with oVEMP, while cognitive dysfunction is related to non-dominant hand function.

  4. A combined pulmonary function and emphysema score prognostic index for staging in Chronic Obstructive Pulmonary Disease.

    Full Text Available Chronic Obstructive Pulmonary Disease (COPD is characterized by high morbidity and mortality. Lung computed tomography parameters, individually or as part of a composite index, may provide more prognostic information than pulmonary function tests alone.To investigate the prognostic value of emphysema score and pulmonary artery measurements compared with lung function parameters in COPD and construct a prognostic index using a contingent staging approach.Predictors of mortality were assessed in COPD outpatients whose lung computed tomography, spirometry, lung volumes and gas transfer data were collected prospectively in a clinical database. Univariate and multivariate Cox proportional hazard analysis models with bootstrap techniques were used.169 patients were included (59.8% male, 61.1 years old; Forced Expiratory Volume in 1 second % predicted: 40.5±19.2. 20.1% died; mean survival was 115.4 months. Age (HR = 1.098, 95% Cl = 1.04-1.252 and emphysema score (HR = 1.034, 95% CI = 1.007-1.07 were the only independent predictors of mortality. Pulmonary artery dimensions were not associated with survival. An emphysema score of 55% was chosen as the optimal threshold and 30% and 65% as suboptimals. Where emphysema score was between 30% and 65% (intermediate risk the optimal lung volume threshold, a functional residual capacity of 210% predicted, was applied. This contingent staging approach separated patients with an intermediate risk based on emphysema score alone into high risk (Functional Residual Capacity ≥210% predicted or low risk (Functional Residual Capacity <210% predicted. This approach was more discriminatory for survival (HR = 3.123; 95% CI = 1.094-10.412 than either individual component alone.Although to an extent limited by the small sample size, this preliminary study indicates that the composite Emphysema score-Functional Residual Capacity index might provide a better separation of high and low risk patients

    Initial poor graft function (IPGF) is a major factor influencing the clinical outcome after liver transplantation (LT), but there is no reliable method to assess and predict graft dysfunction. To help clinicians determine prognosis in the early postoperative period, individual parameters and complex scoring systems have been suggested, but most of them are inaccurate because of the multifactorial nature of transplantation courses. Therefore, the aim of our study was to retrospectively evaluate predictive criteria for retransplantation. Forty-two patients were enrolled in this study: 18 who experienced primary non-function (PNF) and 24 with delayed graft function (DGF). All of the patients were treated with the Molecular Adsorbent Recirculating System (MARS). They were into 3 subgroups: patients who survived without LT (n = 20; 47.7%); patients who underwent LT (n = 16; 37%), and patients who died before transplantation (n = 6; 14%). Stepwise multivariable logistic regression analysis was performed with the intent to find the risk factors for LT or death after MARS treatment (second analysis). Receiver operating characteristic (ROC) curves were performed on significant variables in the logistic regression model with the intent to individually predict variables for LT or death. After a stepwise multivariable logistic regression analysis enrolling all of the previously reported features only 2 variables, tumor necrosis factor (TFN)-α and Glasgow coma score (GCS) score, were statistically significant. TNF-α was an unique independent risk factor for retransplantation or death after MARS treatment (odds ratio [OR] 1.235; P = .013). Conversely, GCS score was protective against retransplantation or death (OR 0.150; P = .003). Starting from these assumptions, a predictive model was created using these 2 variables. On ROC analysis, the combined score showed an area under the curve greater than that of the 2 variables considered separately. Validating these results with a

    The HYDE scoring function consistently describes hydrogen bonding, the hydrophobic effect and desolvation. It relies on HYdration and DEsolvation terms which are calibrated using octanol/water partition coefficients of small molecules. We do not use affinity data for calibration, therefore HYDE is generally applicable to all protein targets. HYDE reflects the Gibbs free energy of binding while only considering the essential interactions of protein-ligand complexes. The greatest benefit of HYDE is that it yields a very intuitive atom-based score, which can be mapped onto the ligand and protein atoms. This allows the direct visualization of the score and consequently facilitates analysis of protein-ligand complexes during the lead optimization process. In this study, we validated our new scoring function by applying it in large-scale docking experiments. We could successfully predict the correct binding mode in 93% of complexes in redocking calculations on the Astex diverse set, while our performance in virtual screening experiments using the DUD dataset showed significant enrichment values with a mean AUC of 0.77 across all protein targets with little or no structural defects. As part of these studies, we also carried out a very detailed analysis of the data that revealed interesting pitfalls, which we highlight here and which should be addressed in future benchmark datasets.

    Traditional patient-reported outcome instruments like the Foot and Ankle Ability Measure (FAAM) quantify patient disability but often are limited by responder burden and incomplete questionnaires. The Patient-Reported Outcome Measurement Information System (PROMIS) overcomes such obstacles through computer-adaptive technology and can capture outcome data from various domains including physical and psychosocial function. Prior work has compared the FAAM with PROMIS physical function; however, there is little evidence comparing the association between foot and ankle-specific tools like the FAAM with more general outcomes measures of PROMIS pain interference and depression in foot and ankle conditions. (1) We asked whether there was a relationship between FAAM Activities of Daily Living (ADL) scores with PROMIS physical function, pain interference, and depression in patients with hallux valgus. (2) Additionally, we asked if we could identify specific factors that are associated with variance in FAAM and PROMIS physical function scores in patients with hallux valgus. Eighty-five new patients with either a primary or secondary diagnosis of hallux valgus based on clinic billing codes from July 2015 to February 2016 were retrospectively identified. Patients completed FAAM ADL paper-based surveys and electronic PROMIS questionnaires for physical function, pain interference, and depression from new patient visits at a single time. Spearman rho correlations were performed between FAAM ADL and PROMIS scores. Analyses then were used to identify differences in FAAM ADL and PROMIS physical function measures based on demographic variables. Stepwise linear regressions then determined which demographic and/or outcome variable(s) accounted for the variance in FAAM ADL and PROMIS physical function scores. FAAM scores correlated strongly with PROMIS physical function (r = 0.70, p < 0.001), moderately with PROMIS pain interference (r = -0.65, p < 0.001), and weakly with PROMIS

    2014-05-01

    We present a knowledge-based function to score protein decoys based on their similarity to native structure. A set of features is constructed to describe the structure and sequence of the entire protein chain. Furthermore, a qualitative relationship is established between the calculated features and the underlying electromagnetic interaction that dominates this scale. The features we use are associated with residue-residue distances, residue-solvent distances, pairwise knowledge-based potentials and a four-body potential. In addition, we introduce a new target to be predicted, the fitness score, which measures the similarity of a model to the native structure. This new approach enables us to obtain information both from decoys and from native structures. It is also devoid of previous problems associated with knowledge-based potentials. These features were obtained for a large set of native and decoy structures and a back-propagating neural network was trained to predict the fitness score. Overall this new scoring potential proved to be superior to the knowledge-based scoring functions used as its inputs. In particular, in the latest CASP (CASP10) experiment our method was ranked third for all targets, and second for freely modeled hard targets among about 200 groups for top model prediction. Ours was the only method ranked in the top three for all targets and for hard targets. This shows that initial results from the novel approach are able to capture details that were missed by a broad spectrum of protein structure prediction approaches.

    Full Text Available This paper proposes an improved score function for the effective ranking order of interval-valued intuitionistic fuzzy sets (IVIFSs and an interval-valued intuitionistic fuzzy TOPSIS method based on the score function to solve multicriteria decision-making problems in which all the preference information provided by decision-makers is expressed as interval-valued intuitionistic fuzzy decision matrices where each of the elements is characterized by IVIFS value and the information about criterion weights is known. We apply the proposed score function to calculate the separation measures of each alternative from the positive and negative ideal solutions to determine the relative closeness coefficients. According to the values of the closeness coefficients, the alternatives can be ranked and the most desirable one(s can be selected in the decision-making process. Finally, two illustrative examples for multicriteria fuzzy decision-making problems of alternatives are used as a demonstration of the applications and the effectiveness of the proposed decision-making method.

    Full Text Available Objective. The purpose of this study was to determine whether mobility and physical activity were associated with lung function in adults with cystic fibrosis (CF. Design. This was a prospective cohort observational study in an urban, academic, specialized care center. Participants were ambulatory, nonhospitalized adults with CF. Main Outcome Measures. Mobility was assessed monthly by the Life-Space Assessment (LSA questionnaire and quarterly by pedometer. Lung function was assessed by spirometry. Results. Twenty-seven subjects participated. Subjects recorded mean pedometer steps of 20,213 ± 11,331 over three days and FEV1% predicted of 77.48% ± 22.60% over one year. The LSA score at enrollment was correlated with initial pedometer steps (r=0.42 and P=0.03, and mean LSA score over one year was correlated with mean number of steps (r=0.51 and P=0.007. LSA mobility and pedometer scores were correlated with FEV1% predicted at enrollment and throughout the study. Conclusions. Mobility and physical activity measured by LSA questionnaire and pedometer are positively associated with lung function in adults with CF. This study confirms the importance of mobility and physical activity and supports the utility of a simple office-based questionnaire as a measure of mobility in adults with CF.

    Fifty-one patients with mild (n = 14), moderate (n = 10) and severe traumatic brain injury (n = 27)received early rehabilitation. Level of consciousness was evaluated using the Glasgow Coma Score. Functional level was determined using the Glasgow Outcome Score, whilst mobility was evaluated using the Mobility Scale for Acute Stroke. Activities of daily living were assessed using the Barthel Index. Following Bobath neurodevelopmental therapy, the level of consciousness was significantly improved in patients with moderate and severe traumatic brain injury, but was not greatly influenced in patients with mild traumatic brain injury. Mobility and functional level were significantly improved in patients with mild, moderate and severe traumatic brain injury. Gait recovery was more obvious in patients with mild traumatic brain injury than in patients with moderate and severe traumatic brain injury. Activities of daily living showed an improvement but this was insignificant except for patients with severe traumatic brain injury. Nevertheless, complete recovery was not acquired at discharge. Multiple regression analysis showed that gait and Glasgow Coma Scale scores can be considered predictors of functional outcomes following traumatic brain injury.

    Protein-protein complexes are known to play key roles in many cellular processes. However, they are often not accessible to experimental study because of their low stability and difficulty to produce the proteins and assemble them in native conformation. Thus, docking algorithms have been developed to provide an in silico approach of the problem. A protein-protein docking procedure traditionally consists of two successive tasks: a search algorithm generates a large number of candidate solutions, and then a scoring function is used to rank them. To address the second step, we developed a scoring function based on a Voronoï tessellation of the protein three-dimensional structure. We showed that the Voronoï representation may be used to describe in a simplified but useful manner, the geometric and physico-chemical complementarities of two molecular surfaces. We measured a set of parameters on native protein-protein complexes and on decoys, and used them as attributes in several statistical learning procedures: a logistic function, Support Vector Machines (SVM), and a genetic algorithm. For the later, we used ROGER, a genetic algorithm designed to optimize the area under the receiver operating characteristics curve. To further test the scores derived with ROGER, we ranked models generated by two different docking algorithms on targets of a blind prediction experiment, improving in almost all cases the rank of native-like solutions. http://genomics.eu.org/spip/-Bioinformatics-tools-

    Mexican-origin adolescent mothers are at increased risk for poor psychosocial functioning as a result of various stressors with which they must contend; however, existing theory suggests that cultural strengths may help mitigate the negative effects of stress. As such, the current study examined the associations between cultural and economic stressors and Mexican-origin adolescent mothers' (N = 207; M age = 16.23 years, SD = 1.0) internalizing and externalizing behaviors, as well as the degree to which ethnic identity affirmation and familism values moderated these links. Adolescent mothers who reported higher levels of discrimination, acculturative stress, and economic stress also reported higher depressive symptoms and greater involvement in risky behaviors. Importantly, ethnic identity affirmation minimized the negative associations between cultural stressors and adolescents' involvement in risky behaviors, with the associations being weakest among adolescents with high levels of ethnic identity. Familism appeared to serve a protective function under conditions of low levels of discrimination, but not under conditions of high levels of discrimination. Findings are discussed with special attention to the developmental and cultural contexts in which these adolescent mothers' lives are embedded, and implications for future research and practice are presented.

    The long-term effects of extreme war-related trauma on the second and the third generation of Holocaust survivors (HS) were examined in 88 middle-class families. Differences in functioning between adult offspring of HS (HSO) and a comparison group, as well as the psychosocial functioning of adolescent grandchildren of HS, were studied. Degree of presence of Holocaust in the family was examined in families in which both parents were HSO, either mother or father was HSO, and neither parent was HSO. Mothers' Holocaust background was associated with higher levels of psychological distress and less positive parenting representations. In line with synergic (multiplicative) models of risk, adolescents in families where both parents were HSO perceived their mothers as less accepting and less encouraging independence, and reported less positive self-perceptions than their counterparts. They also perceived their fathers as less accepting and less encouraging independence, showed higher levels of ambivalent attachment style, and according to their peers, demonstrated poorer adjustment during military basic training than their fellow recruits from the one-parent HSO group. Parents and adolescents in the one-parent HSO group functioned similarly to others with no Holocaust background. Parenting variables mediated the association across generations between degree of Holocaust experience in the family of origin of the parents and ambivalent attachment style and self-perception of the adolescents. It is recommended that researchers and clinicians develop awareness of the possible traces of trauma in the second and the third generation despite their sound functioning in their daily lives.

    Full Text Available Multigene assays such as the 21-gene recurrence score (RS quantify risk for recurrence and potential benefit from chemotherapy in early-stage, ER+ breast cancers. Few studies have assessed the impact of testing on patient-reported outcomes such as cancer-related distress or quality of life. The few studies that have assessed these outcomes do not consider potential modifiers, such as the patients’ level of involvement in the treatment decision-making process. In the current study, 81 breast cancer patients who received the RS assay completed cross-sectional surveys. We used linear multiple regression to assess whether test result, decision-making role (passive versus shared/active, and their interaction contributed to current levels of distress, quality of life, and decisional conflict. There were no associations between these variables and test result or decision-making role. However, women who received an intermediate RS and took a passive role in their care reported higher-cancer-related distress and cancer worry and lower quality of life than those who took a shared or active role. These data should be confirmed in prospective samples, as these poorer outcomes could be amenable to intervention.

  1. RAId_aPS: MS/MS analysis with multiple scoring functions and spectrum-specific statistics.

    Full Text Available Statistically meaningful comparison/combination of peptide identification results from various search methods is impeded by the lack of a universal statistical standard. Providing an E-value calibration protocol, we demonstrated earlier the feasibility of translating either the score or heuristic E-value reported by any method into the textbook-defined E-value, which may serve as the universal statistical standard. This protocol, although robust, may lose spectrum-specific statistics and might require a new calibration when changes in experimental setup occur. To mitigate these issues, we developed a new MS/MS search tool, RAId_aPS, that is able to provide spectrum-specific-values for additive scoring functions. Given a selection of scoring functions out of RAId score, K-score, Hyperscore and XCorr, RAId_aPS generates the corresponding score histograms of all possible peptides using dynamic programming. Using these score histograms to assign E-values enables a calibration-free protocol for accurate significance assignment for each scoring function. RAId_aPS features four different modes: (i compute the total number of possible peptides for a given molecular mass range, (ii generate the score histogram given a MS/MS spectrum and a scoring function, (iii reassign E-values for a list of candidate peptides given a MS/MS spectrum and the scoring functions chosen, and (iv perform database searches using selected scoring functions. In modes (iii and (iv, RAId_aPS is also capable of combining results from different scoring functions using spectrum-specific statistics.

    Full Text Available Background: Traumatic brain injury (TBI constitutes a significant public health problem. Objectives: To assess cognitive, functional, and psychosocial outcome in patients with severe TBI (STBI. Materials and Methods: A total of 77 survivors of STBI treated at our center were prospectively assessed in the outpatient department 1 year after the injury. These patients were assessed for cognitive, functional, and psychosocial outcome using cognitive outcome tests, dysfunctional analysis questionnaire, and personality trait inventory, respectively. Cognitive and functional outcome was graded as average and above average recovery (good recovery or below average recovery (poor recovery. Psychosocial outcome was assessed as average recovery (good recovery or mild impairment and severe impairment (poor to very poor recovery. Statistical analysis was done using Chi-square and Fisher′s exact tests. Results: The ability to learn new things was most affected aspect of cognitive function and only 1% of patients had good recovery in this domain. However, 44% had good outcome for simple memory. A total of 61% showed good recovery in several aspects of functional status. At the end of 1 year, 62.5% patients still remained unemployed. 45.4% patients had good recovery, while 37% had severe impairment for various personality traits and 40% of patients had impaired emotional stability, while 57% patients showed impaired recovery in depressive tendency. Conclusion: In this study 61% patients with STBI had good recovery in functional outcome and 45.4% in psychosocial outcome at 1 year follow-up. However, improvement in cognitive outcome was not so optimistic with the ability to learn new things being most affected.

    The effect of maturity on Functional Movement Screen (FMS) scores in elite, adolescent soccer players was examined. A cross-sectional observational study was completed. Participants were 1163 male English Football League soccer players (age 8-18 years). Players were mid-foundation phase (MF) (U9); late foundation phase (LF) (U10 and U11); early youth development phase (EYD) (U12 and U13); mid-youth development (MYD) phase (U14-U15); Late Youth Development Phase (LYD) (U16) and early professional development phase (EPD) (U18). Age from peak height velocity was estimated and players were categorized as pre- or post-peak height velocity (PHV). To analyse where differences in FMStotal score existed we separated the screen into FMSmove (3 movement tests); FMSflex (2 mobility tests) and FMSstab (2 stability tests). FMStotal median score ranged from 11 at MF to 14 for EPD. There was a substantial increase (10%) in those able to achieve a score of ≥14 on FMStotal in those who were post-PHV compared to pre-PHV. This was explained by a substantial increase in those achieving a score of ≥4 on FMSstab (21%). There was a substantial increase in the proportion of players who achieved the FMStotal threshold of ≥14 with an increase of 47.5 (41.4-53.6)% from the MF phase to the EPD phase due to improvements in FMSmove and FMSstab. PHV and maturity have substantial effects on FMS performance. FMS assessment appears to be invalid for very young players. Findings are relevant to those analyzing movement in soccer players.

    Full Text Available Due to the recent financial crisis and European debt crisis, credit risk evaluation has become an increasingly important issue for financial institutions. Reliable credit scoring models are crucial for commercial banks to evaluate the financial performance of clients and have been widely studied in the fields of statistics and machine learning. In this paper a novel fuzzy support vector machine (SVM credit scoring model is proposed for credit risk analysis, in which fuzzy membership is adopted to indicate different contribution of each input point to the learning of SVM classification hyperplane. Considering the methodological consistency, support vector data description (SVDD is introduced to construct the fuzzy membership function and to reduce the effect of outliers and noises. The SVDD-based fuzzy SVM model is tested against the traditional fuzzy SVM on two real-world datasets and the research results confirm the effectiveness of the presented method.

    2011-01-01

    The disturbance of the hypothalamic-pituitary- adrenal axis characteristic of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is likely to affect brain development, yet neuroanatomic work is only beginning. Fetal hyperandrogenemia in 46, XX 21-OHD leads to masculinized brain organization and, consequently, at later stages of development, to masculinized gender-related behavior and cognitive function, including, although relatively uncommonly, gender identity. Genital masculinization as well as its surgical treatment has implications for social stigmatization and sexual functioning. CAH-associated electrolyte crises in infancy and later may result in severe cognitive impairment. Psychiatric disorders are somewhat increased, especially in patients with severe degrees of CAH.

  8. Optimizing Scoring Function of Protein-Nucleic Acid Interactions with Both Affinity and Specificity

    2013-01-01

    Protein-nucleic acid (protein-DNA and protein-RNA) recognition is fundamental to the regulation of gene expression. Determination of the structures of the protein-nucleic acid recognition and insight into their interactions at molecular level are vital to understanding the regulation function. Recently, quantitative computational approach has been becoming an alternative of experimental technique for predicting the structures and interactions of biomolecular recognition. However, the progress of protein-nucleic acid structure prediction, especially protein-RNA, is far behind that of the protein-ligand and protein-protein structure predictions due to the lack of reliable and accurate scoring function for quantifying the protein-nucleic acid interactions. In this work, we developed an accurate scoring function (named as SPA-PN, SPecificity and Affinity of the Protein-Nucleic acid interactions) for protein-nucleic acid interactions by incorporating both the specificity and affinity into the optimization strategy. Specificity and affinity are two requirements of highly efficient and specific biomolecular recognition. Previous quantitative descriptions of the biomolecular interactions considered the affinity, but often ignored the specificity owing to the challenge of specificity quantification. We applied our concept of intrinsic specificity to connect the conventional specificity, which circumvents the challenge of specificity quantification. In addition to the affinity optimization, we incorporated the quantified intrinsic specificity into the optimization strategy of SPA-PN. The testing results and comparisons with other scoring functions validated that SPA-PN performs well on both the prediction of binding affinity and identification of native conformation. In terms of its performance, SPA-PN can be widely used to predict the protein-nucleic acid structures and quantify their interactions. PMID:24098651

    2014-02-01

    According to the DSM, functional impairment is a main criterion for the general definition of personality disorders (PDs), but research suggests that some PDs might not be related to impaired functioning. Occupational functioning has rarely been examined in all ten DSM PDs. We analysed 511 adults aged 20-41 years from the general population of the canton of Zurich, Switzerland, using data from the Epidemiology Survey of the Zurich Programme for Sustainable Development of Mental Health Services. All PDs were assessed with dimensional trait-scores and associations with indicators of occupational functioning were analysed with generalised linear models. Each PD revealed at least a weak association with some form of occupational impairment. Most PDs, especially from cluster A and B, were significantly related to occupational dysfunction, in particular low education level, conflicts in the workplace, dismissal or demotion, and unemployment. In contrast, obsessive-compulsive PD was mostly unrelated to occupational functioning. A total personality pathology dose-response relationship was observed for low education level, conflicts in the workplace, dismissal or demotion, and unemployment. Impairment in occupational functioning is an important aspect particularly of cluster A and B PDs. Assuming that functional impairment is a predictor of illness severity, we advocate that clinicians should carefully explore indicators of occupational functioning in the diagnosis, prognosis, and treatment of PDs. The findings discussed herein have implications for general treatment, interventions in the work environment, or re-integration of patients into the labour force.

    Full Text Available This study aimed to determine whether psychological factors affect health-related quality of life (HRQL and recovery of knee function in total knee replacement (TKR patients. A total of 119 TKR patients (male: 38; female: 81 completed the Beck Anxiety Inventory (BAI, Beck Depression Inventory (BDI, State Trait Anxiety Inventory (STAI, Eysenck Personality Questionnaire-revised (EPQR-S, Knee Society Score (KSS, and HRQL (SF-36. At 1 and 6 months after surgery, anxiety, depression, and KSS scores in TKR patients were significantly better compared with those preoperatively (P<0.05. SF-36 scores at the sixth month after surgery were significantly improved compared with preoperative scores (P<0.001. Preoperative Physical Component Summary Scale (PCS and Mental Component Summary Scale (MCS scores were negatively associated with extraversion (E score (B=-0.986 and -0.967, respectively, both P<0.05. Postoperative PCS and State Anxiety Inventory (SAI scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991, respectively, both P<0.05. Postoperative MCS, SAI, Trait Anxiety Inventory (TAI, and BAI scores were also negatively associated with the N score (B=-0.367, -0.107, -0.281, and -0.851, respectively, all P<0.05. The KSS function score at the sixth month after surgery was negatively associated with TAI and N scores (B=-0.315 and -0.532, respectively, both P<0.05, but positively associated with the E score (B=0.215, P<0.05. The postoperative KSS joint score was positively associated with postoperative PCS (B=0.356, P<0.05. In conclusion, for TKR patients, the scores used for evaluating recovery of knee function and HRQL after 6 months are inversely associated with the presence of negative emotions.

    Vertebral compression fractures can result from advanced osteoporosis, or less commonly from metastatic or traumatic insults to the vertebral column, and result in disabling pain and decreased functional capacity. Various vertebral augmentation options including kyphoplasty aim at preventing the sequelae of pain and immobility that can develop as the result of the vertebral fractures. The mechanism for pain relief following kyphoplasty is not entirely understood, and the restoration of a portion of the lost vertebral height is a subject of debate. We retrospectively reviewed radiographic imaging, pain relief, analgesic intake and functional outcomes in 67 consecutive patients who underwent single- or multilevel kyphoplasty with the primary goal of quantifying the restoration of lost vertebral height. We observed a mean of 45% of the lost vertebral height restored postprocedurally. Secondarily, kyphoplasty was associated with significant decreases in pain scores, daily morphine consumption and improvement in patient-reported functional measures.

    Little is known about the impact of family environment on the long-term adjustment of patients with juvenile-onset fibromyalgia (JFM). Our objective was to evaluate whether family environment in early adolescence predicted later physical functioning and depressive symptoms of adolescents with JFM as they transitioned to early adulthood in the context of a controlled long-term followup study. Participants consisted of 39 youth (mean age 18.7 years) with JFM and 38 healthy matched controls who completed web-based surveys about their health status (Short Form 36 health survey) and depressive symptoms (Beck Depression Inventory II) ~4 years after a home-based, in-person assessment of child and family functioning. During the initial assessment, parents of the participants (94% mothers) completed the Family Environment Scale and adolescents (mean age 14.8 years) completed self-report questionnaires about pain (visual analog scale) and depressive symptoms (Children's Depression Inventory). The results indicated that family environment during early adolescence significantly predicted greater depressive symptoms in early adulthood for both the JFM group and the healthy controls. In particular, a controlling family environment (use of rules to control the family and allowing little independence) during early adolescence was the driving factor in predicting poorer long-term emotional functioning for patients with JFM. Family environment did not significantly predict longer-term physical impairment for either group. Adolescents with JFM from controlling family environments are at an increased risk for poorer emotional functioning in early adulthood. Behavioral and family interventions should foster independent coping among adolescents with JFM and greater parenting flexibility to enhance successful long-term coping.

    2009-01-01

    In this paper we present two empirical scoring functions, PLANTS(CHEMPLP) and PLANTS(PLP), designed for our docking algorithm PLANTS (Protein-Ligand ANT System), which is based on ant colony optimization (ACO). They are related, regarding their functional form, to parts of already published scoring functions and force fields. The parametrization procedure described here was able to identify several parameter settings showing an excellent performance for the task of pose prediction on two test sets comprising 298 complexes in total. Up to 87% of the complexes of the Astex diverse set and 77% of the CCDC/Astex clean listnc (noncovalently bound complexes of the clean list) could be reproduced with root-mean-square deviations of less than 2 A with respect to the experimentally determined structures. A comparison with the state-of-the-art docking tool GOLD clearly shows that this is, especially for the druglike Astex diverse set, an improvement in pose prediction performance. Additionally, optimized parameter settings for the search algorithm were identified, which can be used to balance pose prediction reliability and search speed.

    Depressive disorders often co-occur with personality disorders. The extent to which depressive disorders influence treatment outcome in personality disorders remains unclear. The aim of this study was to determine the impact of co-morbid depression on recovery from personality disorders and improvements in psychosocial functioning. This study drew data from a randomized-controlled trial in which patients (N = 320) with cluster-c (92%), paranoid, histrionic and/or narcissistic personality disorders received schema-therapy, treatment-as-usual, or clarification-oriented psychotherapy. Recovery from personality disorders at three-year follow-up and improvements in psychosocial functioning over a course of three years was predicted by the diagnostic status of depressive disorders at baseline using mixed model regression analyses. Based on the number of axis-I and axis-II disorders, personality disorder severity and global symptomatic distress and functioning a baseline severity index was computed and included in subsequent analyses to test the specificity of baseline depression in predicting outcomes. Patients with co-occurring depression reported higher baseline severity compared to patients without co-occurring depression. Depression at baseline was associated with lower recovery rates at three-year follow-up (p = 0.01) but this effect disappeared after controlling for baseline severity. Patients with depression at baseline reported higher psychosocial impairments throughout treatment (p personality disorders but this effect disappears when general severity is taken into account. Patients with primarily cluster-c personality disorders and co-occurring depression might benefit from additional depression treatment in terms of improved psychosocial functioning.

    Full Text Available BACKGROUND Previous studies on the measurement of intelligence in students with learning difficulties indicate low stability of results observed over time. Therefore, careful analysis of changes in intelligence quotient, as well as in results within Verbal and Performance scale subtests, is necessary. PARTICIPANTS AND PROCEDURE The aim of the research was to analyze changes in WISC-R scores over time in students with borderline intellectual functioning. Test-retest stability of WISC-R was evaluated for Full, Verbal (VIQ, and Performance (PIQ scales. The study involved 30 students, who were tested three times, when their mean age was 8, 10.8, and 13.6 years old. RESULTS The results showed that Full Scale IQ was fairly stable over time and remained below the average level, between –1.01 and –2.00 standard deviations. Significant changes were observed in the Verbal and Performance scale; VIQ decreased and PIQ increased over time. An initially insignificant statistical difference between the scales grew as time progressed. Furthermore, considerable subtest score fluctuation was observed; over time scores in the Vocabulary subtest significantly decreased whereas in Block Design and Picture Arrangement they increased. CONCLUSIONS The authors argue that delayed acquisition of verbal skills may result from chronic school failure and deficiency of educational support experienced by this group of students. Meanwhile, non-verbal skills, that are less dependent on educational influences and academic knowledge, improve with students’ development through their engagement in everyday life activities.

    2010-01-01

    Objectives: Text categorization has been used in biomedical informatics for identifying documents containing relevant topics of interest. We developed a simple method that uses a chi-square-based scoring function to determine the likelihood of MEDLINE citations containing genetic relevant topic. Methods: Our procedure requires construction of a genetic and a nongenetic domain document corpus. We used MeSH descriptors assigned to MEDLINE citations for this categorization task. We compared frequencies of MeSH descriptors between two corpora applying chi-square test. A MeSH descriptor was considered to be a positive indicator if its relative observed frequency in the genetic domain corpus was greater than its relative observed frequency in the nongenetic domain corpus. The output of the proposed method is a list of scores for all the citations, with the highest score given to those citations containing MeSH descriptors typical for the genetic domain. Results: Validation was done on a set of 734 manually annotate...

    The initial gain from a Pulmonary Rehabilitation Program (PRP) among patients with chronic obstructive pulmonary disease (COPD) begins to fade away 6 months after the completion of a rehabilitation program. One possible reason may be due to the poor compliance of the patients to the existing forms of home exercise program (e.g., walking, weight training activities, etc.). This study tested the efficacy of health qigong (HQG), a traditional Chinese exercise, as an adjunct home exercise program in optimizing the gains obtained from PRP until 6 months after discharge. This was a randomized controlled trial (RCT) on a mind-body exercise intervention. Eighty (80) patients with COPD receiving conventional PRP pulmonary rehabilitation program were randomized to the HQG intervention group (n = 40) and control group (n = 40). Assessments were undertaken by blinded assessors at baseline, discharge from training, and follow-up (FU) at 3 and 6 months. Primary outcomes involved functional capacity scales and secondary outcomes involved quality-of-life scales. Intention-to-treat analysis identified trends of improvement in all outcome measures in the HQG group, whereas lesser improvement and trends of deteriorations were identified in the control group. Ancillary analysis using a per-protocol method, however, identified significantly better improvements in functional capacity measures among the HQG at the 6-month FU. This RCT provided some evidence to support the positive effect of HQG as an adjunct home exercise for rehabilitation among people with COPD and to support further related research.

Patients were divided into three groups by AT% severity. We examined AT% correlations with oxygen saturation (SO2 at rest, six-minute walk distance (6MWD, minimum SO2 during the six-minute walk test (6MWT_SO2, FVC, FEV1, FEV1/FVC, and clinical parameters.RESULTS: The 6MWD was longer in the patients with larger normal lung volumes (r = 0.53. We found that AT%950 showed significant correlations (before and after the exclusion of outliers, respectively with the clinical score (r = 0.72; 0.80, FVC (r = 0.24; 0.59, FEV1 (r = −0.58; −0.67, and FEV1/FVC (r = −0.53; r = −0.62, as did AT%DM with the clinical score (r = 0.58; r = 0.63, SO2 at rest (r = −0.40; r = −0.61, 6MWT_SO2 (r = −0.24; r = −0.55, FVC (r = −0.44; r = −0.80, FEV1 (r = −0.65; r = −0.71, and FEV1/FVC (r = −0.41; r = −0.52.CONCLUSIONS: Our results show that AT% correlates significantly with clinical scores and pulmonary function test results in children with OB.

    The relationship between racial discrimination, parental functioning, and child adjustment is not well understood. The goal of the present study was to assess parental reports of discrimination in relation to depression and parenting practices, as well as on subsequent child internalizing and externalizing problems in low-income Black families. Data include a subsample of the Early Steps project, a multisite longitudinal study of financial and behaviorally at-risk families. Structural equation modeling was used to analyze our hypothesized model. Excellent model fit was established after removing externalizing problems from the model. As predicted, indirect associations were found from discrimination to parental depression, parenting, and child internalizing problems; and direct associations were found from discrimination to child internalizing problems. The results are consistent with findings suggesting that discrimination is negatively associated with adult well-being; moreover, contribute to the sparse literature on the effects of discrimination beyond the direct recipient. Finally, that parent discrimination was directly associated with child emotional problems suggests the continued need to address and treat discriminatory practices more generally.

  3. Syntenator: Multiple gene order alignments with a gene-specific scoring function

    2008-11-01

    Full Text Available Abstract Background Identification of homologous regions or conserved syntenies across genomes is one crucial step in comparative genomics. This task is usually performed by genome alignment softwares like WABA or blastz. In case of conserved syntenies, such regions are defined as conserved gene orders. On the gene order level, homologous regions can even be found between distantly related genomes, which do not align on the nucleotide sequence level. Results We present a novel approach to identify regions of conserved synteny across multiple genomes. Syntenator represents genomes and alignments thereof as partial order graphs (POGs. These POGs are aligned by a dynamic programming approach employing a gene-specific scoring function. The scoring function reflects the level of protein sequence similarity for each possible gene pair. Our method consistently defines larger homologous regions in pairwise gene order alignments than nucleotide-level comparisons. Our method is superior to methods that work on predefined homology gene sets (as implemented in Blockfinder. Syntenator successfully reproduces 80% of the EnsEMBL man-mouse conserved syntenic blocks. The full potential of our method becomes visible by comparing remotely related genomes and multiple genomes. Gene order alignments potentially resolve up to 75% of the EnsEMBL 1:many orthology relations and 27% of the many:many orthology relations. Conclusion We propose Syntenator as a software solution to reliably infer conserved syntenies among distantly related genomes. The software is available from http://www2.tuebingen.mpg.de/abt4/plone.

  4. A Unified Discussion on the Concept of Score Functions Used in the Context of Nonparametric Linkage Analysis

    Directory of Open Access Journals (Sweden)

    Lars Ängquist

    2008-01-01

    Full Text Available In this article we try to discuss nonparametric linkage (NPL score functions within a broad and quite general framework. The main focus of the paper is the structure, derivation principles and interpretations of the score function entity itself. We define and discuss several families of one-locus score function definitions, i.e. the implicit, explicit and optimal ones. Some generalizations and comments to the two-locus, unconditional and conditional, cases are included as well. Although this article mainly aims at serving as an overview, where the concept of score functions are put into a covering context, we generalize the noncentrality parameter (NCP optimal score functions in Ängquist et al. (2007 to facilitate—through weighting—for incorporation of several plausible distinct genetic models. Since the genetic model itself most oftenly is to some extent unknown this facilitates weaker prior assumptions with respect to plausible true disease models without loosing the property of NCP-optimality. Moreover, we discuss general assumptions and properties of score functions in the above sense. For instance, the concept of identical by descent (IBD sharing structures and score function equivalence are discussed in some detail.

    In the framework of the observed-score equating methods for the nonequivalent groups with anchor test design, there are 3 fundamentally different ways of using the information provided by the anchor scores to equate the scores of a new form to those of an old form. One method uses the anchor scores as a conditioning variable, such as the Tucker…

    In structure-based drug design, binding affinity prediction remains as a challenging goal for current scoring functions. Development of target-biased scoring functions provides a new possibility for tackling this problem, but this approach is also associated with certain technical difficulties. We previously reported the Knowledge-Guided Scoring (KGS) method as an alternative approach (BMC Bioinformatics, 2010, 11, 193-208). The key idea is to compute the binding affinity of a given protein-ligand complex based on the known binding data of an appropriate reference complex, so the error in binding affinity prediction can be reduced effectively. In this study, we have developed an upgraded version, i.e. KGS2, by employing 3D protein-ligand interaction fingerprints in reference selection. KGS2 was evaluated in combination with four scoring functions (X-Score, ChemPLP, ASP, and GoldScore) on five drug targets (HIV-1 protease, carbonic anhydrase 2, beta-secretase 1, beta-trypsin, and checkpoint kinase 1). In the in situ scoring test, considerable improvements were observed in most cases after application of KGS2. Besides, the performance of KGS2 was always better than KGS in all cases. In the more challenging molecular docking test, application of KGS2 also led to improved structure-activity relationship in some cases. KGS2 can be applied as a convenient "add-on" to current scoring functions without the need to re-engineer them, and its application is not limited to certain target proteins as customized scoring functions. As an interpolation method, its accuracy in principle can be improved further with the increasing knowledge of protein-ligand complex structures and binding affinity data. We expect that KGS2 will become a practical tool for enhancing the performance of current scoring functions in binding affinity prediction. The KGS2 software is available upon contacting the authors.

    Full Text Available Virtual home-based rehabilitation is an emerging area in stroke rehabilitation. Functional assessment tools are essential to monitor recovery and provide current function-based rehabilitation. We developed the Fugl-Meyer Assessment (FMA tool using Kinect (Microsoft, USA and validated it for hemiplegic stroke patients. Forty-one patients with hemiplegic stroke were enrolled. Thirteen of 33 items were selected for upper extremity motor FMA. One occupational therapist assessed the motor FMA while recording upper extremity motion with Kinect. FMA score was calculated using principal component analysis and artificial neural network learning from the saved motion data. The degree of jerky motion was also transformed to jerky scores. Prediction accuracy for each of the 13 items and correlations between real FMA scores and scores using Kinect were analyzed. Prediction accuracies ranged from 65% to 87% in each item and exceeded 70% for 9 items. Correlations were high for the summed score for the 13 items between real FMA scores and scores obtained using Kinect (Pearson's correlation coefficient = 0.873, P<0.0001 and those between total upper extremity scores (66 in full score and scores using Kinect (26 in full score (Pearson's correlation coefficient = 0.799, P<0.0001. Log transformed jerky scores were significantly higher in the hemiplegic side (1.81 ± 0.76 compared to non-hemiplegic side (1.21 ± 0.43 and showed significant negative correlations with Brunnstrom stage (3 to 6; Spearman correlation coefficient = -0.387, P = 0.046. FMA using Kinect is a valid way to assess upper extremity function and can provide additional results for movement quality in stroke patients. This may be useful in the setting of unsupervised home-based rehabilitation.

    Shoulder trouble, described in the literature as "swimmer's shoulder," has been associated with competitive swimmers. The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is a validated survey used to define functional and performance measures of the upper extremity in overhead athletes. To date, no study has investigated the baseline functional scores for swimmers actively competing in the sport. To establish a baseline score for National Collegiate Athletic Association (NCAA) swimmers actively competing in the sport. Cross-sectional study; Level of evidence, 3. After institutional review board approval, the KJOC Shoulder and Elbow Score was administered to 5 NCAA swim teams (N = 99 participants; 46 men, 53 women). The results on 10 specific individual questions and on the total score were calculated according to the survey's original description. The mean scores were calculated for all participants. The Mann-Whitney U test was used to determine differences between sexes, years swimming, and self-reported injury status. The mean ± SD baseline KJOC score (out of a possible 100) for all participants was 79.0 ± 18.7; the mean score for men was 81.9 ± 15.6 and for women 76.6 ± 20.8. The score for athletes identifying themselves as injured at baseline was 53.9 ± 18.8, compared with 84.4 ± 13.6 for those not reporting as injured (P < .001). Athletes competing ≥11 years had a mean score of 72.0 ± 22.1; those competing ≤10 years scored 86.4 ± 11.4 (P = .007). Baseline scores for swimmers, which were lower than expected, were lower than baseline scores seen in studies of other overhead sports athletes. The data corroborate previous studies identifying swimmers as having a high level of shoulder trouble. Further research is indicated for improving shoulder symptoms and performance in competitive swimmers. © 2015 The Author(s).

    Full Text Available The aim of this study is to investigate the relationship between Hachinski ischemic score (HIS and vascular factors as well as between HIS and the cognitive function in elderly community. Demographic characteristics, such as sex, age, education, history of drinking and smoking, family history of dementia and stroke, diabetes mellitus, hypertension, hyperlipidemia, cardiovascular disease, stroke, and dementia, were surveyed. Neurological examination was administered to every subject and HIS was checked by a neurologist. From a total of 392 participants aged 65 and over in a rural community, 348 completed the survey and were finally enrolled. Among the vascular factors, history of hypertension (P=0.008, history of stroke (P<0.001, family history of dementia (P=0.01, and history of cardiac diseases (P=0.012 showed a significant relationship with HIS. In the cognitive function tests, both Korean version of the Mini-Mental State Examination and the Clinical Dementia Rating (Global and Sum of Boxes had a significant relationship with HIS. Our study suggested HIS may have an association with some vascular factors and cognitive scales in community dwelling elderly. In this study, the HIS seemed to contribute to the evaluation of the quantity of vascular factors and to the prediction of status of cognitive function.

    The potential adverse effect of body mass index (BMI) on shoulder function scores after reverse shoulder arthroplasty (RSA) has not been investigated. We conducted a study to examine outcomes of RSA performed for rotator cuff tear arthropathy (RCTA) across BMI categories (normal weight, overweight, obese). We hypothesized that, compared with normal-weight patients, obese patients would have worse shoulder function scores, worse mobility, and more complications. Using a prospective shoulder arthroplasty registry, we identified 77 primary RSAs performed for RCTA with minimum 2-year follow-up. Thirty-four patients had normal weight (BMI 30 kg/m2). Shoulder function scores, mobility, and satisfaction were evaluated before surgery and at final follow-up. The 3 BMI groups were not significantly different on demographic factors, preoperative shoulder function scores, or preoperative mobility (P > .05). For each group, shoulder function scores and mobility significantly improved between the preoperative and final follow-up assessments (P shoulder function scores, mobility, and patient satisfaction can be expected after RSA for RCTA in patients regardless of BMI.

    Full Text Available Binocular vision is characterized by a harmonious relation between sensory and motor systems of both eyes. This relation enables directing visual axes toward the observed object simultaneously, fusing images from two eyes, and the sense of threedimensionality. Motility and binocular vision disorders occur in manifest and latent strabismus. The irregular position of eyes in strabismus is perceived by most people as an esthetic defect. Also, psychosocial consequences and the importance of treating strabismus are very superficially explained in this context. Bearing in mind the results of recent researches, which indicate that individuals of all ages with strabismus face different difficulties in psychosocial functioning, we believe that this issue in our surroundings should be dealt with. Strabismus leads to forming prejudices which usually have a negative impact on socialization and employment opportunities. Timely treatment of strabismus has a positive influence on the functionality of binocular vision, building self-esteem and self-satisfaction, being accepted by typically developing population, the quality and quantity of social interaction. The aim of this paper is to present the relation between strabismus and psychosocial reactions with regard to the available literature.

    Full Text Available Children and adolescents operated upon for congenital heart disease may show reduced exercise capacity and physical activity, associated with lowered quality of life. This review presents intervention studies on the influence of an exercise program on quality of life and psychosocial functioning in children with severe congenital heart disease. Participation in an exercise program among young people with complex congenital heart disease seemed to have positive effects on quality of life and passive leisure time spent. However, more effects of the exercise programs may have been expected. For future research it is important to critically evaluate the content of the exercise programs.

    Executive function consists of multiple cognitive processes that operate as an interactive system to produce volitional goal-oriented behavior, governed in large part by frontal microstructural and physiological networks. Identification of deficits in executive function in those with neurological or psychiatric conditions can be difficult because the normal variation in executive function test scores, in healthy adults when multiple tests are used, is largely unknown. This study addresses that gap in the literature by examining the prevalence of low scores on a brief battery of executive function tests. The sample consisted of 1,050 healthy individuals (ages 16-89) from the standardization sample for the Delis-Kaplan Executive Function System (D-KEFS). Seven individual test scores from the Trail Making Test, Color-Word Interference Test, and Verbal Fluency Test were analyzed. Low test scores, as defined by commonly used clinical cut-offs (i.e., ≤25th, 16th, 9th, 5th, and 2nd percentiles), occurred commonly among the adult portion of the D-KEFS normative sample (e.g., 62.8% of the sample had one or more scores ≤16th percentile, 36.1% had one or more scores ≤5th percentile), and the prevalence of low scores increased with lower intelligence and fewer years of education. The multivariate base rates (BR) in this article allow clinicians to understand the normal frequency of low scores in the general population. By use of these BRs, clinicians and researchers can improve the accuracy with which they identify executive dysfunction in clinical groups, such as those with traumatic brain injury or neurodegenerative diseases.

    Emotional ups and downs are common among people with Systemic Lupus Erythematosus (SLE) as they live with fears about treatment, pain from the illness and unexpected "flare-ups." The side effects of medications have a severe impact on their self-esteem and lead to psychological distress. This paper reports a study on the impact of a psychosocial group program on the self-esteem and psychosocial functioning of people with SLE. A total of 56 people with SLE were recruited to participate in a 6-week, 2.5-hour weekly session psychosocial group. The group served to equip members with knowledge and skills to cope with SLE and stress arising from the illness, to enhance their self-confidence and develop a positive attitude toward the illness, and to enhance their social support network. The members were assessed before the commencement and during the last session of the groups with Rosenberg's Self-esteem Inventory and General Health Questionnaire (GHQ-30). Results showed that members obtained better scores in self-esteem (p self-esteem and psychosocial functioning of people with SLE after the psychosocial group program. The implications for psychosocial programs for people with SLE are discussed.

    We compare established docking programs, AutoDock Vina and Schrödinger's Glide, to the recently published NNScore scoring functions. As expected, the best protocol to use in a virtual-screening project is highly dependent on the target receptor being studied. However, the mean screening performance obtained when candidate ligands are docked with Vina and rescored with NNScore 1.0 is not statistically different than the mean performance obtained when docking and scoring with Glide. We further demonstrate that the Vina and NNScore docking scores both correlate with chemical properties like small-molecule size and polarizability. Compensating for these potential biases leads to improvements in virtual screen performance. Composite NNScore-based scoring functions suited to a specific receptor further improve performance. We are hopeful that the current study will prove useful for those interested in computer-aided drug design.

    To test observer agreement and two strategies for possible improvement (consensus meeting and reference images) for the modified Chrispin-Norman score for children with cystic fibrosis (CF). Before and after a consensus meeting and after developing reference images three observers scored sets of 25 chest radiographs from children with CF. Observer agreement was tested for line, ring, mottled and large soft shadows, for overinflation and for the composite modified Chrispin-Norman score. Correlation with lung function was assessed. Before the consensus meeting agreement between observers 1 and 2 was moderate-good, but with observer 3 agreement was poor-fair. Scores correlated significantly with spirometry for observers 1 and 2 (-0.72function, but agreement for the modified Chrispin-Norman score did not improve further. Consensus meetings and reference images improve among-observer agreement for the modified Chrispin-Norman score, but good agreement was not achieved among all observers for the modified Chrispin-Norman score and for bronchial line and ring shadows.

  19. Interaction with specific HSP90 residues as a scoring function: validation in the D3R Grand Challenge 2015

    2016-09-01

    Here is reported the development of a novel scoring function that performs remarkably well at identifying the native binding pose of a subset of HSP90 inhibitors containing aminopyrimidine or resorcinol based scaffolds. This scoring function is called PocketScore, and consists of the interaction energy between a ligand and three residues in the binding pocket: Asp93, Thr184 and a water molecule. We integrated PocketScore into a molecular docking workflow, and used it to participate in the Drug Design Data Resource (D3R) Grand Challenge 2015 (GC2015). PocketScore was able to rank 180 molecules of the GC2015 according to their binding affinity with satisfactory performance. These results indicate that the specific residues considered by PocketScore are determinant to properly model the interaction between HSP90 and its subset of inhibitors containing aminopyrimidine or resorcinol based scaffolds. Moreover, the development of PocketScore aimed at improving docking power while neglecting the prediction of binding affinities, suggesting that accurate identification of native binding poses is a determinant factor for the performance of virtual screens.

    Metalloproteins, particularly zinc metalloproteins, are promising therapeutic targets, and recent efforts have focused on the identification of potent and selective inhibitors of these proteins. However, the ability of current drug discovery and design technologies, such as molecular docking and molecular dynamics simulations, to probe metal-ligand interactions remains limited because of their complicated coordination geometries and rough treatment in current force fields. Herein we introduce a robust, multiobjective optimization algorithm-driven metalloprotein-specific docking program named MpSDock, which runs on a scheme similar to consensus scoring consisting of a force-field-based scoring function and a knowledge-based scoring function. For this purpose, in this study, an effective knowledge-based zinc metalloprotein-specific scoring function based on the inverse Boltzmann law was designed and optimized using a dynamic sampling and iteration optimization strategy. This optimization strategy can dynamically sample and regenerate decoy poses used in each iteration step of refining the scoring function, thus dramatically improving both the effectiveness of the exploration of the binding conformational space and the sensitivity of the ranking of the native binding poses. To validate the zinc metalloprotein-specific scoring function and its special built-in docking program, denoted MpSDockZn, an extensive comparison was performed against six universal, popular docking programs: Glide XP mode, Glide SP mode, Gold, AutoDock, AutoDock4Zn, and EADock DSS. The zinc metalloprotein-specific knowledge-based scoring function exhibited prominent performance in accurately describing the geometries and interactions of the coordination bonds between the zinc ions and chelating agents of the ligands. In addition, MpSDockZn had a competitive ability to sample and identify native binding poses with a higher success rate than the other six docking programs.

    Psychosocial factors may significantly affect post-transplant outcomes. The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) was developed as an assessment tool to enhance the pre-transplant psychosocial evaluation. We identified heart, lung, liver, or kidney transplant recipients assessed with the SIPAT pre-transplantation and transplanted between June 1, 2008, and July 31, 2011, at our institution. We analyzed prospectively accumulated psychosocial and medical outcomes at 1 year of follow-up. 217 patients were identified and included in the analysis. The primary outcomes of organ failure and mortality occurred in 12 and 21 patients, respectively, and were not significantly associated with the pre-transplant SIPAT scores. On the other hand, SIPAT scores were significantly correlated with the probability of poor medical and psychosocial outcomes (secondary outcomes). In fact, higher SIPAT scores predicted higher rates of rejection episodes (Spearman ρ = 0.15, 95% 95% confidence interval [CI] = 0.02-0.28, p = .023), medical hospitalizations (ρ = 0.29, 95% CI = 0.16-0.41, p relationship with nonadherence suggested a trend, but no statistical significance was observed (area under the curve = 0.60, 95% CI = 0.50-0.71, p = .058). Study outcomes suggest that SIPAT is a promising pre-transplantation assessment tool that helps identify candidate's areas of psychosocial vulnerability and whose scores are associated with both psychosocial and medical outcomes after transplantation.

    Purpose Stem cell therapy is a promising modality for treatment of patients with chronic cerebrovascular accident (CVA) in whom treatment other than physiotherapy or occupational therapy does not address the repair or recovery of the lost function. In this study, the author aimed at evaluating CVA patients treated with human embryonic stem cell (hESC) therapy and comparing their study outcomes with globally accepted European Stroke Scale (ESS) to that with novel scoring system, Nutech functional score (NFS), a 21-point positional and directional scoring system for assessing patients with CVA. Materials and Methods Patients diagnosed with CVA were assessed with NFS and ESS before and after hESC therapy. NFS assessed the patients in the direction of 1–5 (bad to good), where 5 was considered as the highest possible grade (HPG). The findings were obtained for the patients who scored HPG, and had shown improvement by at least one grade. Results Overall, 66.7% of patients scored HPG level on the NFS scale and about 62.5% of the patients scored HPG according to the ESS scale. Approximately, 52.2% patients showed an improvement of 100% (by at least one grade) on NFS scale. None of the patients showed 100% improvement in the alteration of the score by at least one grade when scored with ESS. Conclusion NFS and ESS scores show that a large population of CVA patients was benefitted with hESC therapy. NFS was found to give more convincing results than ESS, and overcomes the shortcomings of ESS. PMID:28702118

  4. Psychosocial Accompaniment

    Directory of Open Access Journals (Sweden)

    Mary Watkins

    2015-08-01

    Full Text Available This essay advocates for a paradigm shift in psychology toward the activity and ethics of accompaniment. Accompaniment requires a reorientation of the subjectivity, interpersonal practices, and critical understanding of the accompanier so that (she can stand alongside others who desire listening, witnessing, advocacy, space to develop critical inquiry and research, and joint imagination and action to address desired and needed changes. The idea of “accompaniment” emerged in liberation theology in Latin America, and migrated into liberatory forms of psychology as “psychosocial accompaniment.” This essay explores accompaniment and its ethics from a phenomenological perspective, highlighting differences from mainstream stances in psychology. Attention is also given to the effects of accompaniment on the accompanier. Efforts to decolonize psychology require careful attention to the psychic decolonization of its practitioners and to the cultivation of decolonizing interpersonal practices that provide a relational and ethical foundation for joint research, restorative healing, and transformative action. Such practices endeavor through dialogue to build mutual respect and understanding, promote effective solidarity, and contribute to the empowerment of those marginalized. The decolonization of psychology should enable practitioners to be more effective in working for increased social, economic, and environmental justice; peace building and reconciliation; and local and global ecological sustainability.

    Protein Alpha Shape (PAS) Dock is a new empirical score function suitable for virtual library screening using homology modelled protein structures. Here, the score function is used in combination with the geometry search method Tabu search. A description of the protein binding site is generated using gaussian property fields like in Protein Alpha Shape Similarity Analysis (PASSA). Gaussian property fields are also used to describe the ligand properties. The overlap between the receptor and ligand hydrophilicity and lipophilicity fields is maximised, while minimising steric clashes. Gaussian functions introduce a smoothing of the property fields. This makes the score function robust against small structural variations, and therefore suitable for use with homology models. This also makes it less critical to include protein flexibility in the docking calculations. We use a fast and simplified version of the score function in the geometry search, while a more detailed version is used for the final prediction of the binding free energies. This use of a two-level scoring makes PAS-Dock computationally efficient, and well suited for virtual screening. The PAS-Dock score function is trained on 218 X-ray structures of protein- ligand complexes with experimental binding affinities. The performance of PAS-Dock is compared to two other docking methods, AutoDock and MOE-Dock, with respect to both accuracy and computational efficiency. According to this study, PAS-Dock is more computationally efficient than both AutoDock and MOE-Dock, and gives a better prediction of the free energies of binding. PAS-Dock is also more robust against structural variations than AutoDock.

    Full Text Available Abstract Background Successful protein structure prediction requires accurate low-resolution scoring functions so that protein main chain conformations that are close to the native can be identified. Once that is accomplished, a more detailed and time-consuming treatment to produce all-atom models can be undertaken. The earliest low-resolution scoring used simple distance-based "contact potentials," but more recently, the relative orientations of interacting amino acids have been taken into account to improve performance. Results We developed a new knowledge-based scoring function, LoCo, that locates the interaction partners of each individual residue within a local coordinate system based only on the position of its main chain N, Cα and C atoms. LoCo was trained on a large set of experimentally determined structures and optimized using standard sets of modeled structures, or "decoys." No structure used to train or optimize the function was included among those used to test it. When tested against 29 other published main chain functions on a group of 77 commonly used decoy sets, our function outperformed all others in Cα RMSD rank of the best-scoring decoy, with statistically significant p-values Conclusions Our function demonstrates an unmatched combination of accuracy, speed, and simplicity and shows excellent promise for protein structure prediction. Broader applications may include protein-protein interactions and protein design.

    Full Text Available Objectives: Hypertension is a major risk factor for white matter hyperintensities, lacunes, cerebral microbleeds and perivascular spaces, which are MRI markers of cerebral small vessel disease (SVD. Studies have shown associations between these individual MRI markers and cognitive functioning and decline. Recently, a total SVD score was proposed in which the different MRI markers were combined into one measure of SVD, to capture total SVD-related brain damage. We investigated if this SVD score was associated with cognitive decline over 4 years in patients with hypertension. Methods: In this longitudinal cohort study, 130 hypertensive patients (91 patients with uncomplicated hypertension and 39 hypertensive patients with a lacunar stroke were included. They underwent a neuropsychological assessment at baseline and after 4 years. The presence of white matter hyperintensities, lacunes, cerebral microbleeds, and perivascular spaces were rated on baseline MRI. Presence of each individual marker was added to calculate the total SVD score (range 0-4 in each patient. Results: Uncorrected linear regression analyses showed associations between SVD score and decline in overall cognition (p=0.017, executive functioning (p<0.001 and information processing speed (p=0.037, but not with memory (p=0.911. The association between SVD score and decline in overall cognition and executive function remained significant after adjustment for age, sex, education, anxiety and depression score, potential vascular risk factors, patient group and baseline cognitive performance.Conclusions: Our study shows that a total SVD score can predict cognitive decline, specifically in executive function, over 4 years in hypertensive patients. This emphasizes the importance of considering total brain damage due to SVD.

    We explore the psychosocial, demographic, and maternal characteristics across wanted, mistimed, and unwanted pregnancies. Data from 1321 women from a prospective cohort study of pregnant women in Durham, NC, are analyzed. Psychosocial correlates were obtained through prenatal surveys; electronic medical records were used to ascertain maternal health and pregnancy outcomes. Sixty-two percent of the women indicated an unintended pregnancy, with 44% (578) mistimed and 18% (245) unwanted. Only 38% of the pregnancies were characterized as wanted. Women with unwanted and with mistimed pregnancies were similar demographically, but they differed significantly on psychosocial profiles and maternal characteristics. Women with mistimed and with wanted pregnancies differed in demographics and psychosocial profiles. Wanted pregnancies had the healthiest, mistimed an intermediate, and unwanted the poorest psychosocial profile. Women with unwanted pregnancies had the highest depression, perceived stress, and negative paternal support scores (ppsychosocial profiles had higher odds of being in the unwanted category. Controlling for psychosocial and demographic variables, perceived stress and positive paternal support remained significant predictors of belonging to the unwanted and mistimed groups. Fully characterizing pregnancy intention and its relationship to psychosocial profiles may provide a basis for identifying women with highest risk during pregnancy and early motherhood. Women with unwanted and mistimed pregnancies may appear similar demographically but are different psychosocially. Women with unwanted pregnancies have multiple risk factors and would benefit from targeted interventions.

    [Purpose] To investigate the effect of cervical exercise on neck pain, disability, and psychosocial factors in patients with post-traumatic stress disorder. [Subjects] Thirty patients with post-traumatic stress disorder, who also complained of neck pain. [Methods] The cervical exercise group (n = 15) participated in cervical exercises for 30 min, 3 times/week for 6 weeks, and the control group (n = 16) underwent conventional physical therapy alone, without exercise. The exercises were performed in the following order: cervical relaxation, local muscle stabilization, and global muscle stabilization using a sling system. [Results] Compared to the control group, the cervical exercise group demonstrated significant decreases as follows: Visual analogue scale score, 4.2 vs. 1.0; Neck disability index, 3.9 vs. 1.9; and depression on the Symptom checklist-90-revised, 9.4 vs. 4.3 and on the Hopkins symptom checklist-25, 6.3 vs. 2.8. However, anxiety on the Symptom checklist-90-revised (3.1 vs. 1.3) was not significantly different. Effect sizes were as follows: Visual analogue scale score, 1.8; Neck disability index, 0.9; depression, 1.0; and anxiety on Symptom checklist-90-revised and Hopkins symptom checklist-25, 0.6 and 0.8, respectively. [Conclusion] Cervical exercise is effective in improving neck pain, disability, and efficacy of psychological treatment for depression in patients with post-traumatic stress disorder.

    The development and validation of a new knowledge based scoring function (SIScoreJE) to predict binding energy between proteins and ligands is presented. SIScoreJE efficiently predicts the binding energy between a small molecule and its protein receptor. Protein-ligand atomic contact information was derived from a Non-Redundant Data set (NRD) of over 3000 X-ray crystal structures of protein-ligand complexes. This information was classified for individual "atom contact pairs" (ACP) which is used to calculate the atomic contact preferences. In addition to the two schemes generated in this study we have assessed a number of other common atom-type classification schemes. The preferences were calculated using an information theoretic relationship of joint entropy. Among 18 different atom-type classification schemes "ScoreJE Atom Type set2" (SATs2) was found to be the most suitable for our approach. To test the sensitivity of the method to the inclusion of solvent, Single-body Solvation Potentials (SSP) were also derived from the atomic contacts between the protein atom types and water molecules modeled using AQUARIUS2. Validation was carried out using an evaluation data set of 100 protein-ligand complexes with known binding energies to test the ability of the scoring functions to reproduce known binding affinities. In summary, it was found that a combined SSP/ScoreJE (SIScoreJE) performed significantly better than ScoreJE alone, and SIScoreJE and ScoreJE performed better than GOLD::GoldScore, GOLD::ChemScore, and XScore.

    The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the B-B Score results using a smartphone or a reference system have not yet been compared. Provided that the measurement properties are comparable, the use of a smartphone would offer substantial practical advantages. This study investigated the concurrent validity of a smartphone and a reference inertial system for the measurement of the kinematic shoulder function B-B Score. Sixty-five patients with shoulder conditions (with rotator cuff conditions, adhesive capsulitis and proximal humerus fracture) and 20 healthy participants were evaluated using a smartphone and a reference inertial system. Measurements were performed twice, alternating between two evaluators. The B-B Score differences between groups, differences between devices, relationship between devices, intra- and inter-evaluator reproducibility were analysed. The smartphone mean scores (SD) were 94.1 (11.1) for controls and 54.1 (18.3) for patients (P smartphone intra-evaluator ICC was 0.92, the bias 1.5 and the LOA -17.4 to 20.3. The smartphone inter-evaluator ICC was 0.92, the bias 1.5 and the LOA -16.9 to 20.0. The B-B Score results measured with a smartphone were comparable to those of an inertial system. While single measurements diverged in some cases, the intra- and inter-evaluator reproducibility was excellent and was equivalent between devices. The B-B score measured with a smartphone is straightforward and as efficient as a reference inertial system measurement.

    Everard, EM, Harrison, AJ, and Lyons, M. Examining the relationship between the functional movement screen and the landing error scoring system in an active, male collegiate population. J Strength Cond Res 31(5): 1265-1272, 2017-In recent years, there has been an increasing focus on movement screening as the principal aspect of preparticipation testing. Two of the most common movement screening tools are the Functional Movement Screen (FMS) and the Landing Error Scoring System (LESS). Several studies have examined the reliability and validity of these tools, but so far, there have been no studies comparing the results of these 2 screening tools against each other. Therefore, the purpose of this study was to determine the relationship between FMS scores and LESS scores. Ninety-eight male college athletes actively competing in sport (Gaelic games, soccer, athletics, boxing/mixed martial arts, Olympic weightlifting) participated in the study and performed the FMS and LESS screens. Both the 21-point and 100-point scoring systems were used to score the FMS. Spearman's correlation coefficients were used to determine the relationship between the 2 screening scores. The results showed a significant moderate correlation between FMS and LESS scores (rho 100 and 21 point = -0.528; -0.487; p < 0.001). In addition, r values of 0.26 and 0.23 indicate a poor shared variance between the 2 screens. The results indicate that performing well in one of the screens does not necessarily equate to performing well in the other. This has practical implications as it highlights that both screens may assess different movement patterns and should not be used as a substitute for each other.

    Molecular docking of small molecules in the protein binding sites is the most widely used computational technique in modern structure-based drug discovery. Although accurate prediction of binding modes of small molecules can be achieved in most cases, estimation of their binding affinities remains mediocre at best. As an attempt to improve the correlation between the inhibitory constants, pKi, and scoring, we created a new, hybrid scoring function. The new function is a linear combination of the terms of the scoring functions of AutoDock and AutoDock Vina. It was trained on 2,412 protein-ligand complexes from the PDBbind database (www.pdbbind.org.cn, version 2012) and validated on a set of 313 complexes released in the 2013 version as a test set. The new function was included in a modified version of AutoDock. The hybrid scoring function showed a statistically significant improvement in both training and test sets in terms of correlation with and root mean square and mean absolute errors in prediction of pKi values. It was also tested on the CSAR 2014 Benchmark Exercise dataset (team T) and produced reasonably good results.

    Ego development, the capacity to derive coherent, nuanced meaning from one's life experiences, often has significant impact on psychosocial adjustment during adulthood. Research with nonclinical populations has indicated links between higher ego development and healthy emotional coping and interpersonal relationships. Emerging research with substance-abusing mothers suggests that higher levels of ego development are associated with improved parenting but also with increased rates of psychopathology. Less is known about how ego development is related to other psychosocial factors important for substance-abusing mothers' functioning and capacity to parent, including the proclivity to engage in risky behaviors, adaptive coping behaviors, and readiness to engage in psychotherapy. The present study examines these links. Participants included 182 methadonemaintained women who expressed interest in a randomized clinical trial testing the efficacy of a relational parenting intervention for substance-abusing mothers (Luthar, Suchman, & Altomare, 2007). Data were analyzed using a series of MANCOVAs and ANCOVAs controlling for maternal IQ and depression. Mothers with higher levels of ego development reported more adaptive coping techniques and greater readiness to engage in psychotherapy but also reported a heightened desire for strong sensations. Findings are discussed in light of mothers' psychological processes and parenting capacities. The significance of findings for developing parenting interventions for substance-abusing mothers is also discussed.

    Distress conditions during pregnancy may contribute to the development of preeclampsia by altering functions of the neuroendocrine and immune systems, e.g. activation of the hypothalamic-pituitary-adrenal axis and increase in plasma proinflammatory cytokines. Preeclampsia may also precipitate mental health problems due to long-term hospitalization or unpredictable and uncontrollable events such as preterm labor and newborn complications. Besides, preeclampsia may induce persistent neurocognitive complaints with a negative impact on patients' quality of life. As growing evidence indicates that poor maternal mental health has an adverse effect on pregnancy outcome and fetal development, psychosocial interventions may be beneficial for women with preeclampsia.

    The assessment of functionality should include parameters that consider postural control, limb asymmetries, range of motion limitations, proprioceptive deficits, and pain. An increasingly popular battery of tests, the Functional Movement Screen (FMS), is purported to assess the above named parameters. The purpose of our study was twofold: (a) to report differences in total FMS scores in children, provide preliminary normative reference values of each of the 7 individual FMS scores for both genders and report on asymmetries and (b) to evaluate the relationship between total FMS scores, age, body mass index (BMI), core strength/stability, and postural angles to explore the possibility of using the FMS in the assessment of children's functional fitness. Descriptive data on 77 children aged 8-11 years were collected. The children performed core strength/stability exercises. Photographs were taken from a lateral view for later calculation of postural angles. The children performed the FMS while being videotaped for later review. The average total FMS score (of 21) was 14.9 (+1.9), and BMI was 16.4 (+2.2). Static posture is not related to results of the FMS. Core strength was positively correlated to the total FMS score (r = 0.31; p = 0.006). Over 60% demonstrated at least 1 asymmetry. The individual test scores indicate that none of the test items is too difficult for the children. Based on the screen's correlation to core strength, and the fact that it identifies areas of asymmetry, we suggest to further investigate its possible use in the assessment of children's functional fitness.

    We present the third generation of our scoring function for the prediction of protein-ligand binding free energy. This function is now a hybrid between a knowledge-based potential and an empirical function. We constructed a diversified set of ∼1000 complexes from the PDBBinding-CN database for the training of the function, and we show that this number of complexes generates enough data to build the potential. The occurrence of 420 different types of atomic pairwise interactions is computed in up to five different ranges of distances to derive the knowledge-based part. All of the parameters were optimized, and we were able to considerably improve the accuracy of the scoring function with a Pearson correlation coefficient against experimental binding free energies of up to 0.57, which ranks our new scoring function as one of the best currently available and the second-best in terms of standard deviation (SD = 1.68 kcal/mol). The function was then further improved by inclusion of different terms taking into account repulsion and loss of entropy upon binding, and we show that it is capable of recovering native binding poses up to 80% of the time. All of the programs, tools, and protein sets are released in the Supporting Information or as open-source programs.

    A common strategy for virtual screening considers a systematic docking of a large library of organic compounds into the target sites in protein receptors with promising leads selected based on favorable intermolecular interactions. Despite a continuous progress in the modeling of protein-ligand interactions for pharmaceutical design, important challenges still remain, thus the development of novel techniques is required. In this communication, we describe eSimDock, a new approach to ligand docking and binding affinity prediction. eSimDock employs nonlinear machine learning-based scoring functions to improve the accuracy of ligand ranking and similarity-based binding pose prediction, and to increase the tolerance to structural imperfections in the target structures. In large-scale benchmarking using the Astex/CCDC data set, we show that 53.9% (67.9%) of the predicted ligand poses have RMSD of <2 Å (<3 Å). Moreover, using binding sites predicted by recently developed eFindSite, eSimDock models ligand binding poses with an RMSD of 4 Å for 50.0-39.7% of the complexes at the protein homology level limited to 80-40%. Simulations against non-native receptor structures, whose mean backbone rearrangements vary from 0.5 to 5.0 Å Cα-RMSD, show that the ratio of docking accuracy and the estimated upper bound is at a constant level of ∼0.65. Pearson correlation coefficient between experimental and predicted by eSimDock Ki values for a large data set of the crystal structures of protein-ligand complexes from BindingDB is 0.58, which decreases only to 0.46 when target structures distorted to 3.0 Å Cα-RMSD are used. Finally, two case studies demonstrate that eSimDock can be customized to specific applications as well. These encouraging results show that the performance of eSimDock is largely unaffected by the deformations of ligand binding regions, thus it represents a practical strategy for across-proteome virtual screening using protein models. eSimDock is freely

    Childhood traumatic brain injury (CTBI) is one of the most common causes of impairment in children and adolescents, with psychosocial difficulties found to be the most persisting. Given that the transition into adolescence and adulthood can be a stressful period, it is likely that young people who have sustained a CTBI will be more vulnerable to developing psychosocial problems. To date, most research has focused on psychosocial development up to five years following a CTBI and it is unclear how survivors develop in the long-term as young adults. The aim of this research was to track the long-term psychosocial outcomes of children with CTBI and compare them with healthy controls over a period of 16 years. Seventy-five participants with a CTBI and 29 control participants were followed up at five time-points over a period of 16 years. To measure psychosocial functioning (social skills, internalizing, and externalizing symptoms), questionnaires were completed by the primary caregiver acutely (pre-injury baseline), then six months, five years, 10 years, and 16 years post-injury. No significant group differences were found regarding the developmental trajectory of social skills, or internalizing and externalizing symptoms between the CTBI and control groups. The severe CTBI group demonstrated a trend of lower social skills, while the mild CTBI group showed a trend of higher internalizing and externalizing skills at six months, five years, and ten years post-CTBI event, compared with other groups. The mild CTBI group scored in the borderline range for externalizing symptoms six months post-CTBI; however, all other mean scores were within the normal range. Over a period of 16 years, young adults with CTBI showed similar developmental trajectories regarding psychosocial outcomes, compared with healthy controls. This study confirmed previous literature that CTBI is associated with increased levels of psychosocial problems.

    Important long-term health problems have been described after severe paediatric trauma. The International Classification of Functioning (ICF) was developed as a universal framework to describe that health. We evaluated outcome in children after 'severe' trauma (defined as: hospitalised >48 h) by means of a questionnaire based on this ICF construct (IROS). Questionnaires were sent to children; one year after this trauma and to 'control' children without any previous 'severe' trauma. We created propensity score-matched pairs (n = 133) and evaluated differences in health perception. IROS characteristics were investigated by means of Item Response Theory models. We then estimated the health state of each individual based on his/her response pattern (factor score z01) and investigated the effect of selected covariates with simple linear regression. Significant odds ratios for differences between matched groups (p trauma group showed, e.g. significant more physician (estimated relative risk R' 1.7) and psychologist (R' 3.5) visits. IROS primarily provides information from medium to high health burden levels and factor scores ranged from 0.41 (lowest) to 0.967 (highest burden). A significant impact on health burden could only be proven for the 'state at discharge' (p = 0.015), although there was a tendency towards worse factor scores for children that were older, had a higher Injury Severity Score or after traffic injury. In conclusion, we showed that the burden of health problems for children and families after severe trauma is still high and physical, as well as psychosocial in nature. The health state at discharge seems to predict long-term outcome, which might be of importance in view of, e.g. trajectory assistance. IROS may provide an improved scoring system to evaluate outcome after (paediatric) injury or critical illness.

    The early identification of kidney allografts at risk of later dysfunction has implications for clinical practice. Donor quality scoring systems (preoperative) and measures of early allograft function (first week postoperative) have previously shown practical utility. This study aimed to determine the optimal parameter(s) (preoperative and postoperative) with greatest predictive power for the development of subsequent allograft dysfunction.

    While the disease course of stress-induced cardiomyopathy (SIC) is usually benign, it can be fatal. The prognostic factors to predict poorer outcome are not well established, however. We analyzed the Acute Physiology And Chronic Health Evaluation (APACHE) II score to assess its value for predicting poor prognosis in patients with SIC. Thirty-seven consecutive patients with SIC were followed prospectively during their hospitalization. Clinical factors, including APACHE II score, coronary angiogram, echocardiography and cardiac enzymes at presentation were analyzed. Of the 37 patients, 27 patients (73%) were women. The mean age was 66.1 ± 15.6 yr, and the most common presentation was chest pain (38%). Initial echocardiographic left ventricular ejection fraction (EF) was 42.5% ± 9.3%, and the wall motion score index (WMSI) was 1.9 ± 0.3. Six patients (16%) expired during the follow-up period of hospitalization. Based on the analysis of characteristics and clinical factors, the only predictable variable in prognosis was APACHE II score. The patients with APACHE II score greater than 20 had tendency to expire than the others (P = 0.001). Based on present study, APACHE II score more than 20, rather than cardiac function, is associated with mortality in patients with SIC.

    To compare the psychosocial outcomes of the CenteringPregnancy (CP) model of group prenatal care to individual prenatal care, we conducted a prospective cohort study of women who chose CP group (N = 124) or individual prenatal care (N = 124). Study participants completed the first survey at study recruitment (mean gestational age 12.5 weeks), with 89% completing the second survey (mean gestational age 32.7 weeks) and 84% completing the third survey (6 weeks' postpartum). Multiple linear regression models compared changes by prenatal care model in pregnancy-specific distress, prenatal planning-preparation and avoidance coping, perceived stress, affect and depressive symptoms, pregnancy-related empowerment, and postpartum maternal-infant attachment and maternal functioning. Using intention-to-treat models, group prenatal care participants demonstrated a 3.2 point greater increase (p prenatal planning-preparation coping strategies. While group participants did not demonstrate significantly greater positive outcomes in other measures, women who were at greater psychosocial risk benefitted from participation in group prenatal care. Among women reporting inadequate social support in early pregnancy, group participants demonstrated a 2.9 point greater decrease (p = 0.03) in pregnancy-specific distress in late pregnancy and 5.6 point higher mean maternal functioning scores postpartum (p = 0.03). Among women with high pregnancy-specific distress in early pregnancy, group participants had an 8.3 point greater increase (p prenatal planning-preparation coping strategies in late pregnancy and a 4.9 point greater decrease (p = 0.02) in postpartum depressive symptom scores. This study provides further evidence that group prenatal care positively impacts the psychosocial well-being of women with greater stress or lower personal coping resources. Large randomized studies are needed to establish conclusively the biological and psychosocial benefits of group

    Halogen bonding has recently come to play as a target for lead optimization in rational drug design. However, most docking program don't account for halogen bonding in their scoring functions and are not able to utilize this new approach. In this study a new and improved halogen bonding scoring function (XBSF) is presented along with its implementation in the AutoDock Vina molecular docking software. This new improved program is termed as AutoDock VinaXB, where XB stands for the halogen bonding parameters that were added. XBSF scoring function is derived based on the X···A distance and C-X···A angle of interacting atoms. The distance term was further corrected to account for the polar flattening effect of halogens. A total of 106 protein-halogenated ligand complexes were tested and compared in terms of binding affinity and docking poses using Vina and VinaXB. VinaXB performed superior to Vina in the majority of instances. VinaXB was closer to native pose both above and below 2 Å deviation categories almost twice as frequently as Vina. Implementation of XBSF into AutoDock Vina has been shown to improve the accuracy of the docking result with regards to halogenated ligands. AutoDock VinaXB addresses the issues of halogen bonds that were previously being scored unfavorably due to repulsion factors, thus effectively lowering the output RMSD values.

    To compare the perioperative and early renal functional outcomes of RPN with OPN for kidney tumors. A total of 209 RPN or OPN patients with availability of preoperative cross-sectional imaging since 2009 at our center were included. To adjust for potential baseline confounders propensity-score matching was performed, which resulted in 94 OPNs matched to 51 RPNs. Perioperative and early renal functional outcomes were compared. In propensity-score matched analysis, RPN procedures were well tolerated and resulted in significant decreases in postoperative analgesic time (24 vs. 48 hr, pscale (3 vs. 4, prisk of EBL≥400 ml (OR: 0.488; p = 0.212). When adjusted for potential selection biases, RPN offers comparable perioperative and early renal functional outcomes to those of OPN, with the added advantage of improved postoperative pain control and a shorter LOS.

    Full Text Available Abstract Background Empirical studies investigating the prevalence of mental disorders and psychological distress in cancer patients have gained increasing importance during recent years, particularly with the objective to develop and implement psychosocial interventions within the cancer care system. Primary purpose of this epidemiological cross-sectional multi-center study is to detect the 4-week-, 12-month-, and lifetime prevalence rates of comorbid mental disorders and to further assess psychological distress and psychosocial support needs in cancer patients across all major tumor entities within the in- and outpatient oncological health care and rehabilitation settings in Germany. Methods/Design In this multicenter, epidemiological cross-sectional study, cancer patients across all major tumor entities will be enrolled from acute care hospitals, outpatient cancer care facilities, and rehabilitation centers in five major study centers in Germany: Freiburg, Hamburg, Heidelberg, Leipzig and Würzburg. A proportional stratified random sample based on the nationwide incidence of all cancer diagnoses in Germany is used. Patients are consecutively recruited in all centers. On the basis of a depression screener (PHQ-9 50% of the participants that score below the cutoff point of 9 and all patients scoring above are assessed using the Composite International Diagnostic Interview for Oncology (CIDI-O. In addition, all patients complete validated questionnaires measuring emotional distress, information and psychosocial support needs as well as quality of life. Discussion Epidemiological data on the prevalence of mental disorders and distress provide detailed and valid information for the estimation of the demands for the type and extent of psychosocial support interventions. The data will provide information about specific demographic, functional, cancer- and treatment-related risk factors for mental comorbidity and psychosocial distress, specific

    Protein-protein (P-P) 3D structures are fundamental to structural biology and drug discovery. However, most of them have never been determined. Many docking algorithms were developed for that purpose, but they have a very limited accuracy in generating native-like structures and identifying...... the most correct one, in particular when a single answer is asked for. With such a low success rate it is difficult to point out one docked structure as being native-like. Here we present a new, high accuracy, scoring method to identify the 3D structure of P-P complexes among a set of trial poses...... the trial structures and identifies the native-like structures with unprecedented accuracy (∼94%), providing the correct P-P 3D structures that biochemists and molecular biologists need to pursue their studies. With such a success rate, the bottleneck of protein-protein docking moves from the scoring...

    Beyond the Framingham Stroke Risk Score, prediction of future stroke may improve with a genetic risk score (GRS) based on single-nucleotide polymorphisms associated with stroke and its risk factors. The study includes 4 population-based cohorts with 2047 first incident strokes from 22,720 initially stroke-free European origin participants aged ≥55 years, who were followed for up to 20 years. GRSs were constructed with 324 single-nucleotide polymorphisms implicated in stroke and 9 risk factors. The association of the GRS to first incident stroke was tested using Cox regression; the GRS predictive properties were assessed with area under the curve statistics comparing the GRS with age and sex, Framingham Stroke Risk Score models, and reclassification statistics. These analyses were performed per cohort and in a meta-analysis of pooled data. Replication was sought in a case-control study of ischemic stroke. In the meta-analysis, adding the GRS to the Framingham Stroke Risk Score, age and sex model resulted in a significant improvement in discrimination (all stroke: Δjoint area under the curve=0.016, P=2.3×10(-6); ischemic stroke: Δjoint area under the curve=0.021, P=3.7×10(-7)), although the overall area under the curve remained low. In all the studies, there was a highly significantly improved net reclassification index (Pstroke and its risk factors result only in a small improvement in prediction of future stroke compared with the classical epidemiological risk factors for stroke.

    Balance problems and falls are a common concern among individuals with Parkinson's disease (PD). Falls frequently occur during daily activities such as reaching into cupboards in the kitchen or bathroom. This study compared the correlation among two standard postural stability tests - the postural stability score on the Unified Parkinson's Disease Rating Scale (UPDRS) and the Functional Reach Test (FRT) - and ecologically valid reaching tasks that correspond to reaching at different cupboard heights among 20 individuals with PD and 20 age-matched controls. Both the FRT and the UPDRS postural stability tests are quick measures that can be performed during the clinical examination. The FRT, but not the postural stability score, demonstrated a significant correlation with the ecologically valid reaching tasks, among individuals with PD. Furthermore the FRT scores did not correlate with the UPDRS postural stability scores, indicating that these are measuring different aspects of balance. This study suggests that the FRT score may better predict the risk of postural instability encountered during daily activities among individuals with PD.

    Several tests have recently been developed to measure changes in patient strength and functional outcomes in the intensive care unit (ICU). The original Physical Function ICU Test (PFIT) demonstrates reliability and sensitivity. The aims of this study were to further develop the original PFIT, to derive an interval score (the PFIT-s), and to test the clinimetric properties of the PFIT-s. A nested cohort study was conducted. One hundred forty-four and 116 participants performed the PFIT at ICU admission and discharge, respectively. Original test components were modified using principal component analysis. Rasch analysis examined the unidimensionality of the PFIT, and an interval score was derived. Correlations tested validity, and multiple regression analyses investigated predictive ability. Responsiveness was assessed using the effect size index (ESI), and the minimal clinically important difference (MCID) was calculated. The shoulder lift component was removed. Unidimensionality of combined admission and discharge PFIT-s scores was confirmed. The PFIT-s displayed moderate convergent validity with the Timed "Up & Go" Test (r=-.60), the Six-Minute Walk Test (r=.41), and the Medical Research Council (MRC) sum score (rho=.49). The ESI of the PFIT-s was 0.82, and the MCID was 1.5 points (interval scale range=0-10). A higher admission PFIT-s score was predictive of: an MRC score of ≥48, increased likelihood of discharge home, reduced likelihood of discharge to inpatient rehabilitation, and reduced acute care hospital length of stay. Scoring of sit-to-stand assistance required is subjective, and cadence cutpoints used may not be generalizable. The PFIT-s is a safe and inexpensive test of physical function with high clinical utility. It is valid, responsive to change, and predictive of key outcomes. It is recommended that the PFIT-s be adopted to test physical function in the ICU.

    The ketogenic diet is an effective therapy for childhood epilepsy, but its important impacts on families could affect successful treatment. We assessed medical and psychosocial factors associated with successful ketogenic diet treatment. A total of 23 families of patients treated with ketogenic diet completed questionnaires (30% response), including inquiries about challenges to successful dietary treatments and validated family functioning scales. Of these, 14 were considered successful (diet discontinued once the child was seizure-free or continued as clinically indicated). Family-identified challenges were food preparation time (n = 11) and that the diet was too restrictive (n = 9). Neither Medicaid insurance nor family functioning scale scores were significantly associated with successful treatment. Lower seizure frequency prior to ketogenic diet initiation (P = .02) and postdiet seizure improvement (P = .01) were associated with increased odds of success. Effective ketogenic diet treatment is dictated both by psychosocial and epilepsy-related influences. A focus on understanding the psychosocial issues may help to improve families' experiences and success with the ketogenic diet.

    Full Text Available Many children have difficulty producing movements well enough to improve in sensori-motor learning. Previously, we developed a training method that supports active movement generation to allow improvement at a 3D tracing task requiring good compliance control. Here, we tested 7-8 year old children from several 2nd grade classrooms to determine whether 3D tracing performance could be predicted using the Beery VMI. We also examined whether 3D tracing training lead to improvements in drawing. Baseline testing included Beery, a drawing task on a tablet computer, and 3D tracing. We found that baseline performance in 3D tracing and drawing co-varied with the visual perception (VP component of the Beery. Differences in 3D tracing between children scoring low versus high on the Beery VP replicated differences previously found between children with and without motor impairments, as did post-training performance that eliminated these differences. Drawing improved as a result of training in the 3D tracing task. The training method improved drawing and reduced differences predicted by Beery scores.

    The identification of proteins from spectra derived from a tandem mass spectrometry experiment involves several challenges: matching each observed spectrum to a peptide sequence, ranking the resulting collection of peptide-spectrum matches, assigning statistical confidence estimates to the matches, and identifying the proteins. The present work addresses algorithms to rank peptide-spectrum matches. Many of these algorithms, such as PeptideProphet, IDPicker, or Q-ranker, follow similar methodology that includes representing peptide-spectrum matches as feature vectors and using optimization techniques to rank them. We propose a richer and more flexible feature set representation that is based on the parametrization of the SEQUEST XCorr score and that can be used by all of these algorithms. This extended feature set allows a more effective ranking of the peptide-spectrum matches based on the target-decoy strategy, in comparison to a baseline feature set devoid of these XCorr-based features. Ranking using the extended feature set gives 10–40% improvement in the number of distinct peptide identifications relative to a range of q-value thresholds. While this work is inspired by the model of the theoretical spectrum and the similarity measure between spectra used specifically by SEQUEST, the method itself can be applied to the output of any database search. Further, our approach can be trivially extended beyond XCorr to any linear operator that can serve as similarity score between experimental spectra and peptide sequences. PMID:22866926

    Full Text Available BACKGROUND: The development of effective treatments for use by non-specialists is listed among the top research priorities for improving the lives of people with mental illness worldwide. The purpose of this review is to appraise which interventions for children with intellectual disabilities or lower-functioning autism spectrum disorders delivered by non-specialist care providers in community settings produce benefits when compared to either a no-treatment control group or treatment-as-usual comparator. METHODS AND FINDINGS: We systematically searched electronic databases through 24 June 2013 to locate prospective controlled studies of psychosocial interventions delivered by non-specialist providers to children with intellectual disabilities or lower-functioning autism spectrum disorders. We screened 234 full papers, of which 34 articles describing 29 studies involving 1,305 participants were included. A majority of the studies included children exclusively with a diagnosis of lower-functioning autism spectrum disorders (15 of 29, 52%. Fifteen of twenty-nine studies (52% were randomized controlled trials and just under half of all effect sizes (29 of 59, 49% were greater than 0.50, of which 18 (62% were statistically significant. For behavior analytic interventions, the best outcomes were shown for development and daily skills; cognitive rehabilitation, training, and support interventions were found to be most effective for improving developmental outcomes, and parent training interventions to be most effective for improving developmental, behavioral, and family outcomes. We also conducted additional subgroup analyses using harvest plots. Limitations include the studies' potential for performance bias and that few were conducted in lower- and middle-income countries. CONCLUSIONS: The findings of this review support the delivery of psychosocial interventions by non-specialist providers to children who have intellectual disabilities or lower-functioning

    Water plays a significant role in the binding process between protein and ligand. However, the thermodynamics of water molecules are often underestimated, or even ignored, in protein-ligand docking. Usually, the free energies of active-site water molecules are substantially different from those of waters in the bulk region. The binding of a ligand to a protein causes a displacement of these waters from an active site to bulk, and this displacement process substantially contributes to the free energy change of protein-ligand binding. The free energy of active-site water molecules can be calculated by grid inhomogeneous solvation theory (GIST), using molecular dynamics (MD) and the trajectory of a target protein and water molecules. Here, we show a case study of the combination of GIST and a docking program and discuss the effectiveness of the displacing gain of unfavorable water in protein-ligand docking. We combined the GIST-based desolvation function with the scoring function of AutoDock4, which is called AutoDock-GIST. The proposed scoring function was assessed employing 51 ligands of coagulation factor Xa (FXa), and results showed that both scoring accuracy and docking success rate were improved. We also evaluated virtual screening performance of AutoDock-GIST using FXa ligands in the directory of useful decoys-enhanced (DUD-E), thus finding that the displacing gain of unfavorable water is effective for a successful docking campaign.

    Bioinformatic tools are widely utilized to predict functional single nucleotide polymorphisms (SNPs) for genotyping in molecular epidemiological studies. However, the extent to which these approaches are mirrored by epidemiological findings has not been fully explored. In this study, we first surveyed SNPs examined in case-control studies of lung cancer, the most extensively studied cancer type. We then computed SNP functional scores using four popular bioinformatics tools: SIFT, PolyPhen, SNPs3D, and PMut, and determined their predictive potential using the odds ratios (ORs) reported. Spearman's correlation coefficient (r) for the association with SNP score from SIFT, PolyPhen, SNPs3D, and PMut, and the summary ORs were r=-0.36 (p=0.007), r=0.25 (p=0.068), r=-0.20 (p=0.205), and r=-0.12 (p=0.370), respectively. By creating a combined score using information from all four tools we were able to achieve a correlation coefficient of r=0.51 (ptools. Our findings suggest that bioinformatic tools are useful in predicting SNP functionality and may facilitate future genetic epidemiological studies.

    Binding affinity prediction is one of the most critical components to computer-aided structure-based drug design. Despite advances in first-principle methods for predicting binding affinity, empirical scoring functions that are fast and only relatively accurate are still widely used in structure-based drug design. With the increasing availability of X-ray crystallographic structures in the Protein Data Bank and continuing application of biophysical methods such as isothermal titration calorimetry to measure thermodynamic parameters contributing to binding free energy, sufficient experimental data exists that scoring functions can now be derived by separating enthalpic (ΔH) and entropic (TΔS) contributions to binding free energy (ΔG). PHOENIX, a scoring function to predict binding affinities of protein-ligand complexes, utilizes the increasing availability of experimental data to improve binding affinity predictions by the following: model training and testing using high-resolution crystallographic data to minimize structural noise, independent models of enthalpic and entropic contributions fitted to thermodynamic parameters assumed to be thermodynamically biased to calculate binding free energy, use of shape and volume descriptors to better capture entropic contributions. A set of 42 descriptors and 112 protein-ligand complexes were used to derive functions using partial least-squares for change of enthalpy (ΔH) and change of entropy (TΔS) to calculate change of binding free energy (ΔG), resulting in a predictive r2 (r(pred)2) of 0.55 and a standard error (SE) of 1.34 kcal/mol. External validation using the 2009 version of the PDBbind "refined set" (n = 1612) resulted in a Pearson correlation coefficient (R(p)) of 0.575 and a mean error (ME) of 1.41 pK(d). Enthalpy and entropy predictions were of limited accuracy individually. However, their difference resulted in a relatively accurate binding free energy. While the development of an accurate and applicable

    Human growth modeling statistics were utilized to examine how Vineland Adaptive Behavior Scale (VABS) scores changed in individuals with autistic disorder as a function of both age and initial IQ. Results revealed that subjects improved with age in all domains. The rate of growth in Communication and Daily Living Skills was related to initial IQ while rate of growth in Social Skills was not. Results should provide hope for parents and further support for the importance of functional social-communication skills in the treatment of autism.

    Thus, key computational medicinal chemistry methods like molecular dynamics can be used to decipher protein flexibility and to obtain stable models for docking and scoring in food-related studies, and virtual screening is increasingly being applied to identify molecules with potential to act as endocrine disruptors, food mycotoxins, and new nutraceuticals [3,4,5]. All of these methods and simulations are based on protein-ligand interaction phenomena, and represent the basis for any subsequent modification of the targeted receptor's or enzyme's physiological activity. We describe here the energetics of binding of biological complexes, providing a survey of the most common and successful algorithms used in evaluating these energetics, and we report case studies in which computational techniques have been applied to food science issues. In particular, we explore a handful of studies involving the estrogen receptors for which we have a long-term interest.

  6. Sensitivity and Reliability in Incomplete Networks: Centrality Metrics to Community Scoring Functions

    Sarkar, Soumya; Kumar, Suhansanu; Mukherjee, Animesh

    2016-01-01

    Network analysis is an important tool in understanding the behavior of complex systems of interacting entities. However, due to the limitations of data gathering technologies, some interactions might be missing from the network model. This is a ubiquitous problem in all domains that use network analysis, from social networks to hyper-linked web networks to biological networks. Consequently, an important question in analyzing networks is to understand how increasing the noise level (i.e. percentage of missing edges) affects different network parameters. In this paper we evaluate the effect of noise on community scoring and centrality-based parameters with respect to two different aspects of network analysis: (i) sensitivity, that is how the parameter value changes as edges are removed and (ii) reliability in the context of message spreading, that is how the time taken to broadcast a message changes as edges are removed. Our experiments on synthetic and real-world networks and three different noise models demon...

    2011-02-01

    The influence of listening to music on subsequent spatial rotation scores has a controversial history. The effect is unreliable, seeming to depend on several as yet unexplored factors. Using a large sample (167 women, 160 men; M age = 18.9 yr.), two related variables were investigated: participants' sex and the emotion conveyed by the music. Participants listened to 90 sec. of music that portrayed emotions of approach (happiness), or withdrawal (anger), or heard no music at all. They then performed a two-dimensional spatial rotation task. No significant difference was found in spatial rotation scores between groups exposed to music and those who were not. However, a significant interaction was found based on the sex of the participants and the emotion portrayed in the music they heard. Women's scores increased (relative to a no-music condition) only after hearing withdrawal-based music, while men's scores increased only after listening to the approach-based music. These changes were explained using the theory of functional cerebral distance.

    Children with intellectual disability frequently have difficulties in adapting to their environment. The extent of the experienced problems does not only depend on cognitive functioning but is influenced by other factors, such as the presence of a psychiatric disorder or other brain disorders, or adverse environmental factors. Several epidemiological studies show that children with intellectual disabilities are at an increased risk to develop psychiatric disorders. This is also true for youth with a mild intellectual disability and even those with borderline intellectual functioning (mild to borderline intellectual disability (MBID)). Psychiatric disorders are often overlooked because behavioral problems are rather attributed to the intellectual disability. Consequently, effective psychiatric interventions, which are needed to improve the level of functioning, are not applied. This review aimed to systematically evaluate the currently available, qualitatively sound research concerning the effectiveness of psychosocial interventions, specifically directed at psychiatric disorders in children with MBID. Assessed for eligibility were 1409 unique reports, and the review ultimately included only 12 reports. Review of the results and meta-analyses showed that the majority of studies suffer from multiple limitations and that methodological variations between studies are extensive. This possibly reflects the high variance of factors that may be involved in MBID. It will be important in future research to address multi-causality.

The current study aims to establish the equivalence of the total score of the FIM™ motor scale and the Barthel Index through the application of the International Classification of Functioning, Disability and Health, and Rasch measurement theory. Secondary analysis of a large sample of patients with stroke, spinal cord injury, and multiple sclerosis, undergoing rehabilitation was conducted. All patients were assessed at the same time on both the FIM™ and the Barthel Index. The International Classification of Functioning, Disability and Health Linking Rules were used to establish conceptual coherency between the 2 scales, and the Rasch measurement model to establish an exchange of the total scores. Using the FIM™ motor scale, items from both scales linked to the International Classification of Functioning, Disability and Health d4 Mobility or d5 Self-care chapters. Their co-calibration satisfied the assumptions of the Rasch model for each of 3 diagnostic groups. A ceiling effect was observed for the Barthel Index when contrasted against the FIM™ motor scale. Having a Rasch interval metric to transform scores between the FIM™ motor scale and Barthel Index is valuable for monitoring functioning, meta-analysis, quality audits and hospital benchmarking.

    Full Text Available Psychosocial stress affects resources for adequate coping with environmental demands. A crucial question in this context is the extent to which acute psychosocial stressors impact empathy and emotion regulation. In the present study, 120 participants were randomly assigned to a control group vs. a group confronted with the Trier Social Stress Test, an established paradigm for the induction of acute psychosocial stress. Empathy for pain as a specific subgroup of empathy was assessed via pain intensity ratings during a pain-picture task. Self-reported emotion regulation skills were measured as predictors using an established questionnaire. Stressed individuals scored significantly lower on the appraisal of pain pictures. A regression model was chosen to find variables that further predict the pain ratings. These findings implicate that acute psychosocial stress might impair empathic processes to observed pain in another person and the ability to accept one’s emotion additionally predicts the empathic reaction. Furthermore, the ability to tolerate negative emotions modulated the relation between stress and pain judgments, and thus influenced core cognitive-affective functions relevant for coping with environmental challenges. In conclusion, our study emphasizes the necessity of reducing negative emotions in terms of empathic distress when confronted with pain of another person under psychosocial stress, in order to be able to retain pro-social behavior.

    Full Text Available Subjective measurements of cognition have seldom been used in schizophrenia. This is mainly due to the assumption that such measurements lack sensitivity in a disorder characterized by poor insight. We investigated the capacity of BRIEF-A (Behavior Rating Inventory of Executive Function - Adult Version: a self-administered, ecological questionnaire to identify executive deficits in adults with schizophrenia. The global score and each domain-specific score was significantly lower in patients than in healthy controls. BRIEF-A could be a useful complement to objective measurements, providing a subjective assessment of everyday consequences of executive dysfunction in patients with schizophrenia.

    Protein-RNA interactions play important roles in many biological processes. Given the high cost and technique difficulties in experimental methods, computationally predicting the binding complexes from individual protein and RNA structures is pressingly needed, in which a reliable scoring function is one of the critical components. Here, we have developed a knowledge-based scoring function, referred to as ITScore-PR, for protein-RNA binding mode prediction by using a statistical mechanics-based iterative method. The pairwise distance-dependent atomic interaction potentials of ITScore-PR were derived from experimentally determined protein-RNA complex structures. For validation, we have compared ITScore-PR with 10 other scoring methods on four diverse test sets. For bound docking, ITScore-PR achieved a success rate of up to 86% if the top prediction was considered and up to 94% if the top 10 predictions were considered, respectively. For truly unbound docking, the respective success rates of ITScore-PR were up to 24 and 46%. ITScore-PR can be used stand-alone or easily implemented in other docking programs for protein-RNA recognition.

    This study evaluated the effect of 2 dairy cow housing systems on cow locomotion, immune status, and expression of genes associated with lameness during the dry and periparturient periods. Cows were assigned to freestall housing with either rubber (RUB; n = 13) or concrete (CON; n = 14) at the feed-bunk and alley immediately after their first calving, and managed on this system during all subsequent lactations. At dry off, cows were moved to a straw bedded-pack dry cow pen, and remained there until about 2 d before subsequent calving. To investigate whether greater exposure to RUB or CON increased the differences between cows on each treatment, cows at the end of either their first (n = 16) or second (n = 11) lactations were included in the experiment. Locomotion scores and blood samples were obtained at -60 (beginning of the dry period), -30, 0 (after calving), +10 and +18 d relative to calving. Leukocyte counts were obtained by using an automated cell counter. Phagocytic activity, and cells positive for CD14 and CD18 expression were measured by flow cytometry using labeled microbeads and antibodies. Expression of tachikinin 1(TAC1), histamine receptor 1 (H1), and metalloproteinase (MMP)13 in blood leukocytes was estimated using quantitative real-time PCR. Treatment effects were determined using a repeated measures model. Provision of rubber flooring did not improve dairy cow locomotion during the subsequent study period. However, time relative to calving had an effect on locomotion score and speed, which were worst on d 0, probably because of the discomfort associated with calving. An interaction occurred between treatment and time for neutrophil and lymphocyte counts. The RUB cows had greater neutrophil and lesser lymphocyte numbers postpartum than CON. These cows also had more cells positive for CD14 postpartum compared with prepartum. Moreover, RUB cows showed upregulation of MMP13 and TAC1 compared with CON. These genes are associated with lameness and pain

    Psychosocial stress is a major independent risk and prognostic factor of cardiovascular events. It includes psychological, sociological and socioeconomic factors. Cardiovascular diseases are important providers of psychosocial stress. The knowledge of the cerebral development throughout the time allows to a better understanding of the relationship between psychosocial stress and cardiovascular risk. Psychosocial stress leads, on top of traditional cardiovascular risk factors, to the development or to the worsening of an endothelial dysfunction, of an inflammatory response and prothrombotic phenomenon. Anxiolytics and antidepressors are not very effective against psychosocial stress. Physical activity and psychotherapy are much more indicated, particularly cognitve-behavioral therapy. The ESC recommends an evaluation of psychosocial stress through a short questionnaire.

    The ability to design and fine-tune non-covalent interactions between organic ligands and proteins is indispensable to rational drug development. Aromatic stacking has long been recognized as one of the key constituents of ligand-protein interfaces. In this communication, we employ a two-parameter geometric model to conduct a large-scale statistical analysis of aromatic contacts in the experimental and computer-generated structures of ligand-protein complexes, considering various combinations of aromatic amino acid residues and ligand rings. The geometry of interfacial π-π stacking in crystal structures accords with experimental and theoretical data collected for simple systems, such as the benzene dimer. Many contemporary ligand docking programs implicitly treat aromatic stacking with van der Waals and Coulombic potentials. Although this approach generally provides a sufficient specificity to model aromatic interactions, the geometry of π-π contacts in high-scoring docking conformations could still be improved. The comprehensive analysis of aromatic geometries at ligand-protein interfaces lies the foundation for the development of type-specific statistical potentials to more accurately describe aromatic interactions in molecular docking. A Perl script to detect and calculate the geometric parameters of aromatic interactions in ligand-protein complexes is available at https://github.com/michal-brylinski/earomatic.

    In this study, we developed two iterative knowledge-based scoring functions, ITScore_pdbbind(rigid) and ITScore_pdbbind(flex), using rigid decoy structures and flexible decoy structures, respectively, that were generated from the protein-ligand complexes in the refined set of PDBbind 2012. These two scoring functions were evaluated using the 2013 and 2014 CSAR benchmarks. The results were compared with the results of two other scoring functions, the Vina scoring function and ITScore, the scoring function that we previously developed from rigid decoy structures for a smaller set of protein-ligand complexes. A graph-based method was developed to evaluate the root-mean-square deviation between two conformations of the same ligand with different atom names and orders due to different file preparations, and the program is freely available. Our study showed that the two new scoring functions developed from the larger training set yielded significantly improved performance in binding mode predictions. For binding affinity predictions, all four scoring functions showed protein-dependent performance. We suggest the development of protein-family-dependent scoring functions for accurate binding affinity prediction.

    While a wealth of studies have evaluated cross-sectional links between cognition and functioning in schizophrenia, few have investigated the relationship between change in cognition and change in functioning in the context of treatment trials targeted at cognition. Identifying cognitive skills that, when improved, predict improvement in functioning will guide the development of more targeted rehabilitation for this population. The present study identifies the relationship between change in specific cognitive skills and change in functional ability during one year of cognitive rehabilitation. Ninety-six individuals with schizophrenia were assessed with a battery of cognitive measures and a measure of performance-based functioning before and after cognitive training consisting of either drill-and-practice cognitive remediation or computer skills training. Results revealed that while working and episodic memory, problem-solving, and processing speed skills all improved during the trial, only improved working memory and processing speed skills predicted improvement in functional ability. Secondary analyses revealed these relationships were driven by individuals who showed a moderate level (SD≥0.5) of cognitive improvement during the trial. These findings suggest that while a variety of cognitive skills may improve during training targeted at cognition, only improvements in a subset of cognitive functions may translate into functional gains.

To examine physical, cognitive, and social-emotional predictors of quality of life (HRQOL and functional disability (FD in adolescents diagnosed with Neurofibromatosis-1. Methods. Participants were twenty-seven adolescents with a diagnosis of NF-1 who were recruited through an NF-1 specialty clinic at a large Midwestern children’s hospital. Measurements of the adolescents’ cognitive functioning, pain, FD, HRQOL, and social and emotional functioning were obtained with corresponding parent measures. Results. Emotional functioning significantly predicted youth-reported and parent-reported HRQOL, whereas days of pain significantly predicted youth-reported FD. Conclusions. NF-1 is a complex disease. Measurements of the overall impact of the disease tap into different aspects of the effects of NF-1 on daily life. Global outcomes such as HRQOL appear to be influenced especially by emotional functioning, whereas outcomes such as FD appear to be influenced by the physical/organic aspects of NF-1.

This study included 1,686 adults aged 20 or older using the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data, which represent national data in Korea. The key study results were as follows: First, in men, after adjusting for related variables (including body mass index), metabolic syndrome (p=0.005) and MSS (p=0.018) were inversely associated with the homeostatic model assessment of beta cell function (HOMA-B) values. Second, in women, after adjusting for related variables, metabolic syndrome (p=0.616) and MSS (p=0.929) were not associated with HOMA-B levels. In conclusion, metabolic syndrome and MSS were inversely associated with beta cell function in Korean men with obesity, but not in Korean women with obesity.

    Setting the rules for the identification of a stable conformation of a protein is of utmost importance for the efficient generation of structures in computer simulation. For structure prediction, a considerable number of possible models are generated from which the best model has to be selected. Two scoring functions, Rs and Rp, based on the consideration of packing of residues, which indicate if the conformation of an amino acid sequence is native-like, are presented. These are defined using the solvent accessible surface area (ASA) and the partner number (PN) (other residues that are within 4.5 A) of a particular residue. The two functions evaluate the deviation from the average packing properties (ASA or PN) of all residues in a polypeptide chain corresponding to a model of its three-dimensional structure. While simple in concept and computationally less intensive, both the functions are at least as efficient as any other energy functions in discriminating the native structure from decoys in a large number of standard decoy sets, as well as on models submitted for the targets of CASP7. Rs appears to be slightly more effective than Rp, as determined by the number of times the native structure possesses the minimum value for the function and its separation from the average value for the decoys. Two parameters, Rs and Rp, are discussed that can very efficiently recognize the native fold for a sequence from an ensemble of decoy structures. Unlike many other algorithms that rely on the use of composite scoring function, these are based on a single parameter, viz., the accessible surface area (or the number of residues in contact), but still able to capture the essential attribute of the native fold.

    Fetal adversity, evidenced by poor fetal growth for instance, is associated with increased risk for several diseases later in life. Classical cut-offs to characterize small (SGA) and large for gestational age (LGA) newborns are used to define long term vulnerability. We aimed at exploring the possible dynamism of different birth weight cut-offs in defining vulnerability in developmental outcomes (through the Bayley Scales of Infant and Toddler Development), using the example of a gene vs. fetal adversity interaction considering gene choices based on functional relevance to the studied outcome. 36-month-old children from an established prospective birth cohort (Maternal Adversity, Vulnerability, and Neurodevelopment) were classified according to birth weight ratio (BWR) (SGA ≤0.85, LGA >1.15, exploring a wide range of other cut-offs) and genotyped for polymorphisms associated with dopamine signaling (TaqIA-A1 allele, DRD2-141C Ins/Ins, DRD4 7-repeat, DAT1-10- repeat, Met/Met-COMT), composing a score based on the described function, in which hypofunctional variants received lower scores. There were 251 children (123 girls and 128 boys). Using the classic cut-offs (0.85 and 1.15), there were no statistically significant interactions between the neonatal groups and the dopamine genetic score. However, when changing the cut-offs, it is possible to see ranges of BWR that could be associated with vulnerability to poorer development according to the variation in the dopamine function. The classic birth weight cut-offs to define SGA and LGA newborns should be seen with caution, as depending on the outcome in question, the protocols for long-term follow up could be either too inclusive-therefore most costly, or unable to screen true vulnerabilities-and therefore ineffective to establish early interventions and primary prevention.

Methods The Hospital Anxiety and Depression Scale (HADS) was used to evaluate the psychosocial status of FD patients. Mast cell abundance and degranulation rates in the bulb (D1) and second part (D2) of the duodenum were obtained on toluidine blue-stained sections. The relationships among the scores of anxiety (HADS-A) and depression (HADS-D), the MC counts and MC degranulation rates in Dl and D2 were studied. Results HADS-A and HADS-D scores were significantly higher in FD patients than in controls (P <0.05). This was also true for duodenal mast cell abundance (P < 0.01) and degranulation rates (P < 0. 001). Scores of HADS-A and HADS-D were positively correlated with the duodenal mast cell abundance and degranulation rates. Conclusion The abnormal psychosocial status of FD patients is correlated with the increased abundance and degranulation rates of duodenal mast cells.

Therefore, exercises increasing test scores of the FMS may be useful at various stages of sports activity. This study evaluated the effects of the NEURAC sling exercises method on the FMS test score in teenage volleyball players. The study was conducted on 15 volleyball players aged 14 years. The FMS test was performed three times interspersed with a two-month interval. Between the first and the second assessment, neither additional treatment nor training was applied, while between the second and the third assessment, the participants performed stabilisation exercises based on the NEURAC method. Training was carried out twice a week, for eight weeks. The analysis showed that between the first and the second measurement, no significant differences occurred. The use of specific sling exercises caused a significant improvement in FMS results (p ≤ 0.01 between the first and the third, as well as the second and the third measurement. The applied stabilisation exercises based on the NEURAC method positively influenced the FMS test result in male subjects practicing volleyball. Performance of such exercises also resulted in more than 90% of the subjects having a total FMS test score ≥ 17, which may be important in the prevention of injuries. The preliminary results indicate that this type of exercise should be included in a teenage volleyball training routine.

    Correctly ranking protein-ligand interactions with respect to overall free energy of binding is a grand challenge for virtual drug design. Here we compare the performance of various quantum chemical approaches for tackling this so-called "scoring" problem. Relying on systematically generated benchmark sets of large protein/ligand model complexes based on the PDBbind database, we show that the performance depends first of all on the general level of theory. Comparing classical molecular mechanics (MM), semiempirical quantum mechanical (SQM), and density functional theory (DFT) based methods, we find that enhanced SQM approaches perform very similar to DFT methods and substantially different from MM potentials.

    To compare the CT emphysema score with various factors of pulmonary function test by simple spirometry and to use the result as a predictor of pneumothorax in percutaneous transthoracic fine needle aspiration biopsy. The CT scans of 106 patients who had undergone percutaneous transthoracic fine needle aspiration biopsy of lung lesions within the previous 18 months were retrospectively reviewed. In 75 of these 106 cases, the results of the pulmonary function test were also reviewed. On plain chest radiography, pneumothorax was noted in 20 cases (19%). Emphysema was blindly evaluated. We divided each lung into four segments and determined the severity and involved volume of emphysema, as seen on CT. Severity was classified as one of four grades, as follow : absence of emphysema=0 ; low attenuation area of less than 5mm=1 ; low attenuation area of more than 5mm, and vascular pruning with normal lung intervening=2 ; and diffuse low attenuation without intervening normal lung, and larger confluent low attenuation with vascular pruning and distortion of branching pattern occupying all or almost all the involved parenchyma=3. The involved area was also classified as one of four grades : less than 25%=1 ; 25 - 49%=2 ; 51 - 74%=3 ; and more than 75%=4. The CT emphysema score was defined as the average of the grade of severity multiplied by the grade of involved area. Pulmonary function tests, consisting of simple spirometry and a pulmonologist's interpretation, were evaluated. We also evaluated depth and size of lesion as known predisposing factors in postbioptic pneumothorax. Statistical analysis was performed using the chi-square test, Wilcoxon ranks sum W test and the student t test. A comparison between the two groups of occurrence(with or without pneumothorax) showed the emphysema scores to be 1.69{+-}2.0 and 1.11{+-}2.9, respectively ; there was thus no significant difference between the two groups (z= - 0.048, p>0.10). Nor were differences revealed by the

    This study assessed the basic fundamental movements of mixed martial arts (MMA) athletes using the functional movement screen (FMS) assessment and determined if an intervention program was successful at improving results. Participants were placed into 1 of the 2 groups: intervention and control groups. The intervention group was required to complete a corrective exercise program 4 times per week, and all participants were asked to continue their usual MMA training routine. A mid-intervention FMS test was included to examine if successful results were noticed sooner than the 8-week period. Results highlighted differences in FMS test scores between the control group and intervention group (p = 0.006). Post hoc testing revealed a significant increase in the FMS score of the intervention group between weeks 0 and 8 (p = 0.00) and weeks 0 and 4 (p = 0.00) and no significant increase between weeks 4 and 8 (p = 1.00). A χ analysis revealed that the intervention group participants were more likely to have an FMS score >14 than participants in the control group at week 4 (χ = 7.29, p < 0.01) and week 8 (χ = 5.2, p ≤ 0.05). Finally, a greater number of participants in the intervention group were free from asymmetry at week 4 and week 8 compared with the initial test period. The results of the study suggested that a 4-week intervention program was sufficient at improving FMS scores. Most if not all, the movements covered on the FMS relate to many aspects of MMA training. The knowledge that the FMS can identify movement dysfunctions and, furthermore, the fact that the issues can be improved through a standardized intervention program could be advantageous to MMA coaches, thus, providing the opportunity to adapt and implement new additions to training programs.

    Psychosocial rehabilitation (PSR) is an essential component in the management of schizophrenia. It is especially relevant in the improvement of functioning and the quality of life of these individuals. The scarcity of mental health personnel and lack of training in many low and middle income countries (LAMIC) has led to low priority being accorded to PSR. This paper describes some of the PSR initiatives in LAMIC, especially those undertaken after disasters, home-based interventions and community-based rehabilitation programmes.

    Objectives Studies suggest early onset depression (EOD) is associated with a more severe course of the depressive disorder, while late onset depression (LOD) is associated with more cognitive and neuroimaging changes. This study examined if older adults with EOD, compared with those with LOD, would exhibit more severe symptoms of depression and, consistent with the glucocorticoid cascade hypothesis, have more hippocampal volume loss. A second goal was to determine if LOD, compared with EOD, would demonstrate more cognitive and neuroimaging changes. Method At regular intervals over a four year period non-demented, older, depressed adults were assessed on the Mini Mental Status Examination (MMSE) and the Montgomery-Asberg Depression Rating Scale (MADRS). They were also assessed on Magnetic Resonance Imaging (MRI). Results Compared with LOD, EOD had more depressive symptoms, more suicidal thoughts, and less social support. Growth curve analyses indicated that EOD demonstrated higher levels of residual depressive symptoms over time. The LOD group exhibited a greater decrement in cognitive scores. Contrary to the glucocorticoid cascade hypothesis, participants with EOD lost right hippocampal volume at a slower rate than did participants with LOD. Right cerebrum gray matter was initially smaller among participants with LOD. Conclusions EOD is associated with greater severity of depressive illness. LOD is associated with more severe cognitive and neurological changes. These differences are relevant to understanding cognitive impairment in geriatric depression. PMID:22934752

    Full Text Available This study examined the association between anthropometric variables, Functional Movement Screen (FMS scores and 100 m freestyle swimming performance in early adolescent swimmers. Fifty competitive, national level, youth swimmers (21 males, 29 females, mean age ± SD = 13.5 ± 1.5 years, age range 11–16 years performed an “all-out” 100 m freestyle (front crawl swim as fast as they could in a 50 m pool. A median divide for 100 m timed swim was also used to divide the sample into faster or slower groups. Height, body mass, skinfolds and limb lengths were also assessed. Maturation was calculated by proxy using anthropometric measures and participants also undertook the FMS as a measure of functional performance. Backwards linear regression indicated a significant model (p = 0.0001, Adjusted R2 = 0.638 explaining 63.8% of the variance in swim performance with total sum of skinfolds, upper leg length, lower leg length, hand length and total height significantly contributing to the model. Swimmers who were classed as fast had lower total sum of skinfolds (p = 0.005 and higher total FMS score (p = 0.005 compared to their slower peers. In summary, this study indicates that anthropometric variables significantly explained the variance in 100 m freestyle swimming performance in youth swimmers.

    Conclusions: LISTEN can effectively diminish loneliness and decrease the systolic blood pressure in community-dwelling, chronically ill, older adults. Results indicate that this population, if left with untreated loneliness, may experience functional impairment over a period as short as 4 months. Further studies on LISTEN are needed with larger samples, in varied populations, and over longer periods of time to assess the long-term effects of diminishing loneliness in multiple chronic conditions.

  5. Functional, psychosocial and professional outcomes in long-term survivors of lower-extremity osteosarcomas: amputation versus limb salvage.

    As the number of osteosarcoma survivors increases, the impact of quality of life and function needs to be addressed. Limb salvage is the preferred treatment when patients have treatment options; yet, the questionable long-term durability and complications of prostheses, combined with ambiguous function, leave some doubt regarding the best clinical and surgical options. Comparisons between limb salvage patients, amputees and controls also require further investigation. Amputation would leave the patients with a lifelong requirement for an external prosthetic leg associated with an overall limited walking distance. While artificial limbs are much more sophisticated than those used in the past, phantom limb sensations remain a substantial and unpredictable problem in the amputee. Complications such as stump overgrowth, bleeding, and infection, also require further elucidation. Limb salvage surgery using endoprosthesis, allografts or reconstruction is performed in approximately 85% of patients affected by osteosarcoma located in the middle and/or distal femur. One drawback in limb-salvage surgery in the long-term survivor is that endoprostheses have a limited life span with long-term prosthetic failure. The inherent high rate of reoperation remains a serious problem. Replacing a damaged, infected or severely worn-out arthroplastic joint or its intramedullary stem is difficult, especially in the long-stem cemented endoprostheses used in the 1980s. Limb lengthening procedures in patients who have not reached maturity must also be addressed. Periprosthetic infections, compared to other indications for joint reconstruction, were found to be more frequent in patients treated for neoplastic conditions and their outcome can be devastating, resulting in total loss of joint function, amputation, and systemic complications. Quality of life in terms of function, psychological outcome and endpoint achievements such as marriage and employment apparently do not differ significantly

    using analysis of covariance (ANCOVA). No differences were detected between the psychosocial development of PGD children and the control groups. Parents did not differ in reporting problem behaviour and they were stricter than teachers. Concerning family functioning the ART parents scored comparable with each other. PGD and ICSI mothers were emotionally more stable [NEO-FFi Neuroticism/emotionality: P = 0.013, η(2) = 0.066; 95% confidence interval (CI) 95% (0.003;0.148)]. They experienced less parental stress in general [PSI, Total stress: P = 0.001, η(2) = 0.102, 95% CI (0.02;0.192)] and on different sublevels opposed to their SC counterparts. Yet ART mothers presented higher ratings on the NEO-FFi Conscientiousness [P = 0.011, η(2) = 0.064; 95% CI (0.003;0.144)] indicating a higher feeling of competence and goal directedness. Mediation analysis confirmed: PGD and ICSI mothers who experienced less family stress were emotionally more stable. A power analysis indicated that a sample with 152 children is sufficient to detect a medium size effect with 80% power using ANCOVA. The current sample comprised only Dutch speaking Caucasians, hence conclusions should be drawn cautiously. Future research should include larger groups, prematures, multiples and children from different cultural backgrounds. This current research is the first to compare PGD preschoolers with matched controls. Concerns about the behavioural effects on the offspring should not inhibit the use of PGD. Furthermore, our findings suggest that on the long run ART procedures might enhance personal resources of women to cope with family stress. These findings are reassuring for women who might feel insecure and anxious during their ART trajectory.

    AIM: To characterize the patients utilizing a gastroenterology behavioral medicine service and examine the effect of treatment on health care utilization. METHODS: Patients were referred by their gastroenterologists for psychological treatment during a 15 mo period. Patients seen for an intake with a psychologist completed the Brief Symptom Inventory (BSI) and a checklist of psychosocial concerns. A subset of patients with functional bowel disorders also completed a disease specific quality of life measure. Chart review was conducted to obtain information on type and frequency of sessions with the psychologist, the number of outpatient gastroenterology visits, and number of gastroenterology-related medical procedures during the 6 mo following psychological intake. RESULTS: Of 259 patients referred for treatment, 118 (46%) completed an intake with a psychologist. Diagnoses included: irritable bowel syndrome (42%), functional dyspepsia (20%), inflammatory bowel diseases (20%), esophageal symptoms (10%), and “other” (8%). Demographic variables and disease type did not differentiate between those who did and did not schedule an intake. Mean t-scores for the BSI global score index and the depression, anxiety, and somatization subscales fell below the cutoff for clinical significance (t = 63). Treatments were predominantly gut-directed hypnosis (48%) and cognitive behavioral therapy (44%). Average length of treatment was 4 sessions. Among functional gastrointestinal (GI) patients, those patients who initiated treatment received significantly fewer GI-related medical procedures during the 6 mo following the referral than patients who did not schedule an intake [t (197) = 2.69, P < 0.01]. CONCLUSION: Patients are receptive to psychological interventions for GI conditions and there is preliminary evidence that treatment can decrease health-care utilization among patients with functional GI conditions.

    Nipple-sparing prophylactic mastectomy (PM) is an option for women at high-risk for breast cancer, and may offer better cosmetic results than a skin-sparing PM where the nipple-areolar complex (NAC) is removed. However, there may be residual breast cancer risk due to the maintained NAC. It is unclear if sparing the NAC with PM impacts on psychosocial functioning, including cancer-related distress and body image after PM. This was a cross-sectional survey study of women who had undergone bilateral PM (no previous breast cancer) recruited through surgical or cancer genetics clinics. All women completed standardized questionnaires assessing cancer-related distress, anxiety, depression, satisfaction with decision, decision regret, and health-related quality of life related to breast surgery. Outcomes were compared between women with nipple-areola-sparing PM (NAC-PM) and skin-sparing PM (SS-PM). Overall, 137 women completed the study; 53 (39%) had NAC-PM and 84 (61%) had SS-PM. The mean age of the study population was 41.5 years [standard deviation (SD) 8.8] and the mean time between PM and questionnaire completion was 50 months (SD 31). On the BREAST-Q, we found that women with NAC-PM had significantly higher levels of satisfaction with breasts (p = 0.01), satisfaction with outcome (p = 0.02), and sexual well-being (p women with NAC-PM had better body image and sexual functioning compared with women with SS-PM, while both groups had comparable levels of cancer-related distress and perception of breast cancer risk.

    Full Text Available OBJECTIVES: To compare the perioperative and early renal functional outcomes of RPN with OPN for kidney tumors. MATERIALS AND METHODS: A total of 209 RPN or OPN patients with availability of preoperative cross-sectional imaging since 2009 at our center were included. To adjust for potential baseline confounders propensity-score matching was performed, which resulted in 94 OPNs matched to 51 RPNs. Perioperative and early renal functional outcomes were compared. RESULTS: In propensity-score matched analysis, RPN procedures were well tolerated and resulted in significant decreases in postoperative analgesic time (24 vs. 48 hr, p<0.001 and visual analog pain scale (3 vs. 4, p<0.001. Besides, the RPN patients had a significantly shorter LOS (9 vs. 11 days, p = 0.008 and less EBL (100 vs. 200 ml, p<0.001, but median operative time was significantly longer (229 vs. 182 min, p<0.001. Ischemia time, transfusion rates, complication rates, percentage eGFR decline and CKD upstaging were equivalent after RPN versus OPN. In multivariable logistic regression analysis, RPN patients were less likely to have a prolonged LOS (odds ratio [OR]: 0.409; p = 0.016, while more likely to experience a longer operative time (OR: 4.296; p = 0.001. However, the statistical significance for the protective effect of RPN versus OPN in EBL was not confirmed by examining the risk of EBL≥400 ml (OR: 0.488; p = 0.212. CONCLUSIONS: When adjusted for potential selection biases, RPN offers comparable perioperative and early renal functional outcomes to those of OPN, with the added advantage of improved postoperative pain control and a shorter LOS.

    There is little research investigating relationships between the Functional Movement Screen (FMS) and athletic performance in female athletes. This study analyzed the relationships between FMS (deep squat; hurdle step [HS]; in-line lunge [ILL]; shoulder mobility; active straight-leg raise [ASLR]; trunk stability push-up; rotary stability) scores, and performance tests (bilateral and unilateral sit-and-reach [flexibility]; 20-m sprint [linear speed]; 505 with turns from each leg; modified T-test with movement to left and right [change-of-direction speed]; bilateral and unilateral vertical and standing broad jumps; lateral jumps [leg power]). Nine healthy female recreational team sport athletes (age = 22.67 ± 5.12 years; height = 1.66 ± 0.05 m; body mass = 64.22 ± 4.44 kilograms) were screened in the FMS and completed the afore-mentioned tests. Percentage between-leg differences in unilateral sit-and-reach, 505 turns and the jumps, and difference between the T-test conditions, were also calculated. Spearman's correlations (p ≤ 0.05) examined relationships between the FMS and performance tests. Stepwise multiple regressions (p ≤ 0.05) were conducted for the performance tests to determine FMS predictors. Unilateral sit-and-reach positive correlated with the left-leg ASLR (r = 0.704-0.725). However, higher-scoring HS, ILL, and ASLR related to poorer 505 and T-test performance (r = 0.722-0.829). A higher-scored left-leg ASLR related to a poorer unilateral vertical and standing broad jump, which were the only significant relationships for jump performance. Predictive data tended to confirm the correlations. The results suggest limitations in using the FMS to identify movement deficiencies that could negatively impact athletic performance in female team sport athletes.

    Burnout syndrome is common in healthcare workers. We evaluated its prevalence in paediatric residents and investigated its influence on cerebral function correlations, using functional magnetic resonance imaging (MRI), when they carried out an attentional paradigm. This cross-sectional descriptive study involved 28 residents from the Department of Paediatrics at the University of São Paulo. The functional MRI was carried out while the residents completed the Stroop colour word task paradigm to investigate their attentional task performance. The Maslach Burnout Inventory (MBI) was applied, and stress was assessed using the Lipp Inventory of Stress Symptoms for Adults and by a visual analogue mood scale. The MBI subscales of depersonalisation and emotional exhaustion indicated that 53.1% of the residents had moderate or high burnout syndrome. The whole-brain multivariate analysis showed positive correlations between the blood oxygenation level dependent effect and the MBI depersonalisation and emotional exhaustion indices in the dorsolateral prefrontal cortex, which controls for anxiety. Increased brain activation during an attention task, measured using functional MRI, was associated with higher burnout scores in paediatric residents. This study provides a biological basis for the implementation of measures to reduce burnout syndrome at the start of residency training programmes. ©2016 Foundation Acta Paediatrica.

    A recently introduced new methodology based on ultrashort (50-100 ps) molecular dynamics simulations with a quantum-refined force-field (QRFF-MD) is here evaluated in its ability both to predict protein-ligand binding affinities and to discriminate active compounds from inactive ones. Physically based scoring functions are derived from this approach, and their performance is compared to that of several standard knowledge-based scoring functions. About 40 inhibitors of cyclin-dependent kinase 2 (CDK2) representing a broad chemical diversity were considered. The QRFF-MD method achieves a correlation coefficient, R(2), of 0.55, which is significantly better than that obtained by a number of traditional approaches in virtual screening but only slightly better than that obtained by consensus scoring (R(2) = 0.50). Compounds from the Available Chemical Directory, along with the known active compounds, were docked into the ATP binding site of CDK2 using the program Glide, and the 650 ligands from the top scored poses were considered for a QRFF-MD analysis. Combined with structural information extracted from the simulations, the QRFF-MD methodology results in similar enrichment of known actives compared to consensus scoring. Moreover, a new scoring function is introduced that combines a QRFF-MD based scoring function with consensus scoring, which results in substantial improvement on the enrichment profile.

    Stunting is associated with deficits in cognition and school achievement from early childhood to late adolescence; however, there has been little investigation of emotional and behavioral outcomes. The objective of this study was to determine whether linear growth retardation (stunting) in early childhood is associated with poorer psychological functioning in late adolescence. The study was a prospective cohort study of stunted and nonstunted children. Participants were identified at age 9-24 mo by a survey of poor neighborhoods in Kingston, Jamaica, and a 2-y intervention trial of supplementation and stimulation was conducted in the stunted children. Psychological functioning was assessed at age 17 y in 103 of 129 stunted children enrolled and 64 of 84 nonstunted participants. Anxiety, depressive symptoms, self-esteem, and antisocial behavior were reported by participants using interviewer-administered questionnaires and attention deficit, hyperactivity, and oppositional behavior were reported by parent interviews. The stunted participants reported significantly more anxiety (regression coefficient = 3.03; 95% CI = 0.99, 5.08) and depressive symptoms (0.37; 95% CI = 0.01, 0.72) and lower self-esteem (-1.67; 95% CI = -0.38, -2.97) than nonstunted participants and were reported by their parents to be more hyperactive (1.29; 95% CI = 0.12, 2.46). Effect sizes were 0.4-0.5 SD. Participants who received stimulation in early childhood differed from the nonstunted group in hyperactivity only. Children stunted before age 2 y thus have poorer emotional and behavioral outcomes in late adolescence. The findings expand the range of disadvantages associated with early stunting, which affects 151 million children <5 y old in developing countries.

  16. In silico structure-based screening of versatile P-glycoprotein inhibitors using polynomial empirical scoring functions.

    2014-01-01

    P-glycoprotein (P-gp) is an ATP (adenosine triphosphate)-binding cassette transporter that causes multidrug resistance of various chemotherapeutic substances by active efflux from mammalian cells. P-gp plays a pivotal role in limiting drug absorption and distribution in different organs, including the intestines and brain. Thus, the prediction of P-gp-drug interactions is of vital importance in assessing drug pharmacokinetic and pharmacodynamic properties. To find the strongest P-gp blockers, we performed an in silico structure-based screening of P-gp inhibitor library (1,300 molecules) by the gradient optimization method, using polynomial empirical scoring (POLSCORE) functions. We report a strong correlation (r (2)=0.80, F=16.27, n=6, P<0.0157) of inhibition constants (Kiexp or pKiexp; experimental Ki or negative decimal logarithm of Kiexp) converted from experimental IC50 (half maximal inhibitory concentration) values with POLSCORE-predicted constants (KiPOLSCORE or pKiPOLSCORE), using a linear regression fitting technique. The hydrophobic interactions between P-gp and selected drug substances were detected as the main forces responsible for the inhibition effect. The results showed that this scoring technique might be useful in the virtual screening and filtering of databases of drug-like compounds at the early stage of drug development processes.

    The investigation of the complex processes involved in cellular differentiation must be based on unbiased, high throughput data processing methods to identify relevant biological pathways. A number of bioinformatics tools are available that can generate lists of pathways ranked by statistical significance (i.e. by p-value), while ideally it would be desirable to functionally score the pathways relative to each other or to other interacting parts of the system or process. We describe a new computational method (Network Activity Score Finder - NASFinder) to identify tissue-specific, omics-determined sub-networks and the connections with their upstream regulator receptors to obtain a systems view of the differentiation of human adipocytes. Adipogenesis of human SBGS pre-adipocyte cells in vitro was monitored with a transcriptomic data set comprising six time points (0, 6, 48, 96, 192, 384 hours). To elucidate the mechanisms of adipogenesis, NASFinder was used to perform time-point analysis by comparing each time point against the control (0 h) and time-lapse analysis by comparing each time point with the previous one. NASFinder identified the coordinated activity of seemingly unrelated processes between each comparison, providing the first systems view of adipogenesis in culture. NASFinder has been implemented into a web-based, freely available resource associated with novel, easy to read visualization of omics data sets and network modules.

    Full Text Available This study utilized data from over 9,300 youth from 11 national or within-nation ethnic groups to evaluate the relationship between youth religiosity and youth social outcomes (social initiative, antisocial behavior and psychological outcomes (self-esteem and depression considering the roles of religious tradition, national-ethnic group, and gender. We created national-ethnic group by religious tradition (NEG × RT combinations, partitioned religiosity into between-group and within-group components, and performed a series of mixed model regressions for each outcome. The levels of all four outcomes of interest differed significantly across NEG × RT groups, and these differences were attributable to national-ethnic group rather than religious tradition. Youth reports of antisocial behavior and self-esteem were predicted by between-group religiosity. Additionally, within-group religiosity predicted all four outcomes, indicating that the protective role of religiosity functions in a comparative, or relative, manner with youth who are more religious than others in their group reaping the most benefits.

    Maternal depression across the first years of life negatively impacts children's development. One pathway of vulnerability may involve functioning of the hypothalamic-pituitary-adrenal (HPA) axis. We utilize a community cohort of 1983 women with no comorbid risk repeatedly assessed for depression from birth to six years to form two groups; chronically depressed (N=40) and non-depressed (N=91) women. At six years, mother and child underwent psychiatric diagnosis, child salivary cortisol (CT) was assessed three times during a home-visit, mother-child interaction was videotaped, and child empathy was coded from behavioral paradigms. Latent Growth curve Model using Structural Equation Modeling (SEM) estimated the links between maternal depression and mother's negative parenting and three child outcomes; psychopathology, social withdrawal, and empathy as related to child CT baseline and variability. Depressed mothers displayed more negative parenting and their children showed more Axis-I psychopathology and social withdrawal. SEM analysis revealed that maternal depression was associated with reduced CT variability, which predicted higher child psychopathology and social withdrawal. Whereas all children exhibited similar initial levels of CT, children of controls reduced CT levels over time while children of depressed mothers maintained high, non-flexible levels. Mother negativity was related to lower initial CT levels, which predicted decreased empathy. Findings suggest that chronic maternal depression may compromise children's social-emotional adjustment by diminishing HPA-system flexibility as well as limiting the mother's capacity to provide attuned and predictable caregiving.

    Frequently, radiotherapy treatments are comprised of several dose distributions computed or optimized in different patient geometries. Therefore, the need arises to compute the comprehensive biological effect or physical figure of merit of the combined dose of a number of distinct geometry instances. For that purpose the dose is typically accumulated in a reference geometry through deformation fields obtained from deformable image registration. However, it is difficult to establish precise voxel-by-voxel relationships between different anatomical images in many cases. In this work, the mathematical properties of commonly used score functions are exploited to derive an upper boundary for the maximum effect for normal tissue and a lower boundary for the minimum effect for the target of accumulated doses on multiple geometry instances.

    The majority of the older population shows signs of radiographic knee osteoarthritis. However, many remain without functional complaints for a long period. This study aims to find early functional changes associated with stages of radiographic knee osteoarthritis. A group of older people without self-reported complaints was divided in two groups: knee osteoarthritis (K&L = 2-4, N = 29) and control (K&L = 0-1, N = 31). Muscle function was assessed with voluntary and electrically-stimulated isometric knee contractions, including a fatigue test. Physical functioning was assessed with a 6-min walk test (6MWT), a stair climb test (SCT), and a short performance battery. There were no differences in muscle function parameters, 6MWT, and SCT between groups. A clinically relevant lower score on the performance battery was found in participants with knee osteoarthritis. In conclusion, even when older people indicate to have no functional limitations, a decline in functional outcome can be measured with a physical performance battery.

    Abstract The in silico prediction of the functional consequences of mutations is an important goal of human pathogenetics. However, bioinformatic tools that classify mutations according to their functionality employ different algorithms so that predictions may vary markedly between tools. We therefore integrated nine popular prediction tools (PolyPhen-2, SNPs&GO, MutPred, SIFT, MutationTaster2, Mutation Assessor and FATHMM as well as conservation-based Grantham Score and PhyloP) into a single predictor. The optimal combination of these tools was selected by means of a wide range of statistical modeling techniques, drawing upon 10 029 disease-causing single nucleotide variants (SNVs) from Human Gene Mutation Database and 10 002 putatively ‘benign’ non-synonymous SNVs from UCSC. Predictive performance was found to be markedly improved by model-based integration, whilst maximum predictive capability was obtained with either random forest, decision tree or logistic regression analysis. A combination of PolyPhen-2, SNPs&GO, MutPred, MutationTaster2 and FATHMM was found to perform as well as all tools combined. Comparison of our approach with other integrative approaches such as Condel, CoVEC, CAROL, CADD, MetaSVM and MetaLR using an independent validation dataset, revealed the superiority of our newly proposed integrative approach.

    Efflux proteins are membrane proteins, which are involved in the transportation of multidrugs. The annotation of efflux proteins in genomic sequences would aid to understand the function. Although the percentage of membrane proteins in genomes is estimated to be 25-30%, there is no information about the content of efflux proteins. For annotating such class of proteins it is necessary to develop a reliable method to identify efflux proteins from amino acid sequence information. In this work, we have developed a method based on radial basis function networks using position specific scoring matrices (PSSM) and amino acid properties. We noticed that the C-terminal domain of efflux proteins contain vital information for discrimination. Our method showed an accuracy of 78 and 92% in discriminating efflux proteins from transporters and membrane proteins, respectively using fivefold cross-validation. We utilized our method for annotating the genomes E. coli and P. aeruginosa and it predicted 8.7 and 9.2% of proteins as efflux proteins in these genomes, respectively. The predicted efflux proteins have been compared with available experimental data and we observed a very good agreement between them. Further, we developed a web server for classifying efflux proteins and it is freely available at http://rbf.bioinfo.tw/∼sachen/EFFLUXpredict/Efflux-RBF.php. We suggest that our method could be an effective tool for annotating efflux proteins in genomic sequences.

    Transporters are proteins that are involved in the movement of ions or molecules across biological membranes. Transporters are generally classified into channels/pores, electrochemical transporters, and active transporters. Discriminating the specific class of transporters and their subfamilies are essential tasks in computational biology for the advancement of structural and functional genomics. We have systematically analyzed the amino acid composition, residue pair preference and amino acid properties in six different families of transporters. Utilizing the information, we have developed a radial basis function (RBF) network method based on profiles obtained with position specific scoring matrices for discriminating transporters belonging to three different classes and six families. Our method showed a fivefold cross validation accuracy of 76%, 73%, and 69% for discriminating transporters and nontransporters, three different classes and six different families of transporters, respectively. Further, the method was tested with independent datasets, which showed similar level of accuracy. A web server has been developed for discriminating transporters based on three classes and six families, and it is available at http://rbf.bioinfo.tw/ approximately sachen/tcrbf.html. We suggest that our method could be effectively used to identify transporters and discriminating them into different classes and families.

    Oxygen therapy is widely used in emergency and critical care settings, while there is little evidence on its real therapeutic effect. The study aimed to explore the impact of arterial oxygen partial pressure (PaO2) on clinical outcomes in patients with sepsis. A large clinical database was employed for the study. Subjects meeting the diagnostic criteria of sepsis were eligible for the study. All measurements of PaO2 were extracted. The primary endpoint was death from any causes during hospital stay. Survey data analysis was performed by using individual ICU admission as the primary sampling unit. Quadratic function was assumed for PaO2 and its interaction with other covariates were explored. A total of 199,125 PaO2 samples were identified for 11,002 ICU admissions. Each ICU stay comprised 18 PaO2 samples in average. The fitted multivariable model supported our hypothesis that the effect of PaO2 on mortality risk was in quadratic form. There was significant interaction between PaO2 and SAPS-I (p = 0.007). Furthermore, the main effect of PaO2 on SOFA score was nonlinear. The study shows that the effect of PaO2 on mortality risk is in quadratic function form, and there is significant interaction between PaO2 and severity of illness.

    This descriptive study of the perceptions and needs of people with recurrent malignancies asks three questions: How do patients describe the meaning of a recurrence of cancer? Do individuals perceive the diagnosis of recurrence and the initial diagnosis of cancer differently? What are the key psychosocial problems associated with recurrent cancer? The theoretical framework was based on Lazarus and Folkman's theory of stress, appraisal, and coping. Subjects completed the Impact of Event Scale (IES), the Psychosocial Adjustment to Illness Scale--Self-Report (PAIS), and a semistructured qualitative interview. The interview elicited perceptions of the event of recurrence and differences between the diagnosis of recurrence and the initial diagnosis. The convenience sample included 40 patients diagnosed with recurrent cancer within the last 30 days. Many subjects (78%) reported that the recurrence was more upsetting than the initial diagnosis. Scores on both the IES and the PAIS were high when compared to normative samples of patients with cancer suggesting that this sample of patients experienced a lot of psychological distress as well as problems at home, work, and in their social lives. These concerns often were unknown to caregivers. Although more research is needed, the authors propose that, with more accurate assessment, more effective intervention could be implemented and the quality of life improved for patients with recurrent cancer.

    We hypothesized that, in the absence of clinically recognized dementia, cognitive dysfunction measured by the clock draw test (CDT) is associated with greater functional impairment in men and women with peripheral artery disease (PAD). Participants were men and women aged 60 years and older with Mini-Mental Status Examination scores ≥ 24 with PAD (n = 335) and without PAD (n = 234). We evaluated the 6-minute walk test, 4-meter walking velocity at usual and fastest pace, the Short Physical Performance Battery (SPPB), and accelerometer-measured physical activity. CDTs were scored using the Shulman system as follows: Category 1 (worst): CDT score 0–2; Category 2: CDT score 3; Category 3 (best): CDT score 4–5. Results were adjusted for age, sex, race, education, ankle–brachial index (ABI), and comorbidities. In individuals with PAD, lower CDT scores were associated with slower 4-meter usual-paced walking velocity (Category 1: 0.78 meters/second; Category 2: 0.83 meters/second; Category 3: 0.86 meters/second; p-trend = 0.025) and lower physical activity (Category 1: 420 activity units; Category 2: 677 activity units; Category 3: 701 activity units; p-trend = 0.045). Poorer CDT scores were also associated with worse functional performance in individuals without PAD (usual and fast-paced walking velocity and SPPB, p-trend = 0.022, 0.043, and 0.031, respectively). In conclusion, cognitive impairment identified with CDT is independently associated with greater functional impairment in older, dementia-free individuals with and without PAD. Longitudinal studies are necessary to explore whether baseline CDT scores and changes in CDT scores over time can predict long-term decline in functional performance in individuals with and without PAD.

Only 50 patients in sildenafil group and 51 in control group twice completed the International Index of Erectile Function (IIEF and a battery of self-report questionnaires. IIEF scores and psychosocial functioning, self-esteem and support from friends improved only for sildenafil-treated patients (P < 0.001. The high effect sizes suggest that the observed benefits are unlikely to be a placebo effect, although their unspecific nature could not be ruled out. In men with ED associated with AD, sildenafil improves both ED and psychosocial outcomes. Further placebo-controlled clinical trial is warranted.

    Full Text Available In the world, the number of individuals developing severe craniofacial deformities due to trauma, tumor ablation or congenital disorders is increasing every day. These individuals tend to surgical reconstruction to repair these deformities causing adverse effects on body image and to improve functional and/or aesthetic outcomes. Until 2004, reconstructive surgery options to the patients with severe aesthetic facial deformity were rather limited, and the surgical interventions performed back then were far from satisfying functional, aesthetic and psychological expectations of these patients. With the advent of new techniques in surgery, the first partial face transplant was performed in France in 2005, thus emerging as a promising treatment option to patients experiencing serious functional, aesthetic and psychological problems due to facial deformities. Since 2005, 30 face transplants have been successfully performed around the world. Studies have revealed that after face transplant in general patients are satisfied with the functional, aesthetic psychosocial consequences and their quality of life has increased. With the increase in the number of face transplants, certain concepts such as face transplant programs and face transplant teams have gained attention, and nurses have taken their place in this development, providing the necessary care to this group of patients. This literature review is designed to inform nurses, providing care to these patients, about the positive outcomes of face transplant by discussing functional, aesthetic and psychosocial consequences of face transplant in the literature. ÖzetTravma, tümör ablasyonu ya da konjenital hastalıklar nedeniyle yüz bölgesinde ciddi deformite oluşan birey sayısı dünya çapında hızla artmaktadır.

    Targeted therapy is currently a hot topic in the fields of cancer research and drug design. An important requirement for this approach is the development of potent and selective inhibitors for the identified target protein. However, current ways to estimate inhibitor efficacy rely on empirical protein-ligand interaction scoring functions which, suffering from their heavy parameterizations, often lead to a low accuracy. In this work, we develop a nonfitting scoring function, which consists of three terms: (1) gas-phase protein-ligand binding enthalpy obtained by the eXtended ONIOM hybrid method based on an integration of density functional theory (DFT) methods (XYG3 and ωB97X-D) and the semiempirical PM6 method, (2) solvation free energy based on DFT-SMD solvation model, and (3) entropy effect estimated by using DFT frequency analysis. The new scoring function is tested on a cyclin-dependent kinase 2 (CDK2) inhibitor database including 76 CDK2 protein inhibitors and a p21-activated kinase 1 (PAK1) inhibitor database including 20 organometallic PAK1 protein inhibitors. From the results, good correlations are found between the calculated scores and the experimental inhibitor efficacies with the square of correlation coefficient R(2) of 0.76-0.88. This suggests a good predictive power of this scoring function. To the best of our knowledge, this is the first high level theory-based nonfitting scoring function with such a good level of performance. This scoring function is recommended to be used in the final screening of lead structure derivatives.

    Vagally mediated heart rate variability (vmHRV) is reduced in borderline personality disorder (BPD). Non-suicidal self-injury (NSSI) is associated with comorbid psychopathology, in particular BPD. We aimed to examine differences in cardiac function (vmHRV and heart rate [HR]) comparing adolescents (12-17 years) engaging in NSSI (n=30) and healthy controls (n=30). Further, we aimed to determine clinical concomitants of cardiac function in patients with NSSI. Analyses showed no significant group differences on cardiac function. Controlling for a host of confounding variables resting state HR and vmHRV in adolescents with NSSI were significantly correlated with BPD symptoms and the current level of functioning.

  19. Cognitive and psychosocial development concerns in children born small for gestational age.

    Science.gov (United States)

    Lee, Peter A; Houk, Christopher P W

    Outcome information for infants born small for gestational age (SGA), whether term or premature, suggests poorer cognitive function compared with appropriate size for gestational age (AGA) infants. Poorer outcome is associated with smaller size for gestational age and with lack of catch-up growth after birth. Such data have been reported from early childhood to young adulthood. Diminished head circumference at birth and growth thereafter has also been associated with poor outcome. Based on available reports, the impact of SGA birth upon psychosocial development remains unclear. While it has not been shown that growth hormone (GH) therapy impacts either cognitive or psychosocial outcome, increased head circumference standard deviation scores have been shown to occur with GH therapy. These data need to be interpreted with caution since study populations do not define etiology of SGA and definitions of SGA vary. Further, generalized group data are not applicable to individuals.

    To describe patterns of psychosocial adjustment and psychological attributes in preadolescent children as a function of headache status in univariate and adjusted analyses. Target sample of children (n = 8599) was representative of Brazil by demographics. Parents were interviewed using validated headache questionnaires and the "Strengths and Difficulties Questionnaire," which measures behavior in 5 domains. One-year prevalence estimates of headaches were derived by demographics. Relative risk of abnormal Strengths and Difficulties Questionnaire scores were separately modeled in children with episodic migraine and episodic tension-type headache using logistic regression. Sample consisted of 5671 children (65.9% of the target sample), from 5 to 12 years old (49.3% girls). Prevalence estimates in children were 20.6% for "no headache," 9% for episodic migraine, and 12.8% for episodic tension-type headache. Abnormal scores in psychosocial adjustment were significantly more likely in children with episodic migraine, relative to children without headaches and children with episodic tension-type headache, and was significantly influenced by frequency of headache attacks, nausea, school performance, prenatal exposure to tobacco, as well as by phonophobia and photophobia. Children with migraine are at an increased risk of having impairment in psychosocial adjustment, and the factors associated with this impairment have been mapped. Future studies should address the directionality of the association and putative mechanisms to explain it. © 2015 American Headache Society.

    Full Text Available BACKGROUND: While fluid intelligence has proved to be central to executive functioning, logical reasoning and other frontal functions, the role of this ability in psychosocial adaptation has not been well characterized. METHODOLOGY/PRINCIPAL FINDINGS: A random-probabilistic sample of 2370 secondary school students completed measures of fluid intelligence (Raven's Progressive Matrices, RPM and several measures of psychological adaptation: bullying (Delaware Bullying Questionnaire, domestic abuse of adolescents (Conflict Tactic Scale, drug intake (ONUDD, self-esteem (Rosenberg's Self Esteem Scale and the Perceived Mental Health Scale (Spanish adaptation. Lower fluid intelligence scores were associated with physical violence, both in the role of victim and victimizer. Drug intake, especially cannabis, cocaine and inhalants and lower self-esteem were also associated with lower fluid intelligence. Finally, scores on the perceived mental health assessment were better when fluid intelligence scores were higher. CONCLUSIONS/SIGNIFICANCE: Our results show evidence of a strong association between psychosocial adaptation and fluid intelligence, suggesting that the latter is not only central to executive functioning but also forms part of a more general capacity for adaptation to social contexts.

    Background Multiple sequence alignment (MSA) is a crucial step in many molecular analyses and many MSA tools have been developed. Most of them use a greedy approach to construct a first alignment that is then refined by optimizing the sum of pair score (SP-score). The SP-score estimation is thus a bottleneck for most MSA tools since it is repeatedly required and is time consuming. Results Given an alignment of n sequences and L sites, I introduce here optimized solutions reaching O(nL) time complexity for affine gap cost, instead of O(n2L), which are easy to implement.

    BACKGROUND: Whether a major liver resection is safe has been judged mainly from the patient's hepatic reserve. However, a safe limit for liver resection does not exist yet. This study aimed to construct a new scoring system as a guide to determine a safe limit for liver resection and avoid liver dysfunction after hepatectomy. METHODS: Eighty-six patients with hepatocellular carcinoma who had undergone hepatectomy in West China Hospital from March 2007 to June 2010 were reviewed. The patients were classified according to the levels of total bilirubin after hepatectomy and the parameters in the perioperative period were compared. Receiver operating characteristic (ROC) analysis was made to assess the liver function compensatory (LFC) value to predict liver dysfunction of the patients after hepatectomy. LFC value is defined as the preoperative KICG value×22.487+standard remnant liver volume (SRLV)×0.020. RESULTS: Patients were classified into group I (normal group, n=69) and group II (with total bilirubin >85.5 μmol/L for 7 days after hepatectomy, n=17) based on the levels of total bilirubin after hepatectomy. Group II was further divided into two subgroups: recovered subgroup (n=14) and fatal subgroup (n=3). There were no significant differences in preoperative data or intraoperative findings except the indocyanine green test parameters (KICG and ICG R15) and SRLV. ROC analysis showed that the sensitivity and specificity of an LFC value ≤13.01 were 94.1% and 82.6% respectively for predicting liver dysfunction of the patients after hepatectomy. CONCLUSIONS: The LFC value appears to be a good predictor of postoperative liver dysfunction in patients who undergo hepatectomy for HCC. An expected LFC value of 13.01 seems to be a safe limit for liver resection.

    "Psychosocial stress" is an increasingly common concept in the challenging and highly-demanding modern society of today. Organic response to stress implicates two major components of the stress system,namely the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. Stress is anamnestically reported by patients during the course of disease, usually accompanied by a decline in their overall health status. As the mechanisms involving glucocorticoids and catecholamines have been deciphered, and their actions on immune cell function deeper understood, it has become clear that stress has an impact on hepatic inflammatory response. An increasing number of articles have approached the link between psychosocial stress and the negative evolution of hepatic diseases. This article reviews a number of studies on both human populations and animal models performed in recent years, all linking stress, mainly of psychosocial nature, and the evolution of three important liver-related pathological entities: viral hepatitis, cirrhosis and hepatocellular carcinoma.

    The aim of this study was to investigate whether the parenchymal lung damage in patients suffering from cystic fibrosis (CF) can be equivalently quantified by the Chrispin-Norman (CN) scores determined with low-field magnetic resonance imaging (MRI) and conventional chest radiography (CXR). Both scores were correlated with pulmonary function tests (PFT) and the Shwachman-Kulczycki method (SKM). To evaluate the comparability of MRI and CXR for different states of the disease, all scores were applied to patients divided into three age groups. Seventy-three CF patients (mean SKM score: 62 {+-} 8) with a median age (range) of 14 years (7-32) were included. The mean CN scores determined with both imaging methods were comparable (CXR: 12.1 {+-} 4.7; MRI: 12.0 {+-} 4.5) and showed high correlation (P < 0.05, R = 0.97). Only weak correlations were found between imaging, PFT, and SKM. Both imaging modalities revealed significantly more severe disease expression with age, while PFT and SKM failed to detect early signs of disease. We conclude that imaging of the lung in CF patients is capable of detecting subtle and early parenchymal destruction before lung function or clinical scoring is affected. Furthermore, low-field MRI revealed high consistency with chest radiography and may be used for a thorough follow-up while avoiding radiation exposure. (orig.)

    Background Psychosocial outcomes from the Prevention of Recurrent Episodes of Depression with Venlafaxine ER for Two Years (PREVENT) study were evaluated. Methods Adult outpatients with recurrent major depressive disorder (MDD) and response or remission following 6-month continuation treatment with venlafaxine extended release (ER) were randomized to receive venlafaxine ER or placebo for 1 year. Patients without recurrence on venlafaxine ER during year 1 were randomized to venlafaxine ER or placebo for year 2. Psychosocial functioning was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire—Short Form (Q-LES-Q), Life EnjoymentScale—Short Version (LES-S), Social Adjustment Scale—Self-Report (SAS-SR) total and individual factors, Short Form Health Survey (SF-36) (vitality, social functioning, and role function-emotional items), and Longitudinal Interval Follow-up Evaluation (LIFE). Results At year 1 end, better overall psychosocial functioning was seen among patients randomly assigned to venlafaxine ER (n=129) vs placebo (n=129), with significant differences at end point on SF-36 role function-emotional, Q-LES-Q, and SAS-SR total, and work, house work, social/leisure, and extended-family factor scores (p≤0.05). At year 2 end, significant differences favored venlafaxine ER (n=43) vs placebo (n=40)on SF-36 vitality and rolefunction-emotional, Q-LES-Q, LES-S, LIFE, and SAS-SR total, social/leisure, and extended-family factor scores (p≤0.05). Limitations Patients with chronic MDD or treatment resistance were excluded and long-term specialist care was a financial incentive for treatment compliance. Discontinuation-related adverse events may have compromised the integrity of the treatment blind. Conclusions For patients with recurrent MDD, 2 years’ maintenance therapy with venlafaxine ER may improve psychosocial functioning vs placebo. PMID:20510459

    Full Text Available Neuroticism may have great impact on mental and physical health in both sexes. The aims of this study were to explore whether relationships between neuroticism scores and psychosocial indicators as well as metabolic syndrome in a population of incoming university students existed in the different sexes. In total, 4266 incoming students were included in this study. The test battery comprised a self-administered structured questionnaire, including the neuroticism subscale of the Maudsley Personality Inventory, the 12-item Chinese Health Questionnaire, the Chinese Internet Addiction Scale-Revision, the measurement of support functions, and the Pittsburgh Sleep Quality Index. Multivariate logistic regression showed that higher Pittsburgh Sleep Quality Index scores, higher Chinese Internet Addiction Scale-Revision scores, and higher 12-item Chinese Health Questionnaire scores were significantly correlated with neuroticism in both sexes, but lower perceived routine support: measurement of support functions scores were associated only with the male participants. No significant differences were found in terms of body mass index or other metabolic profiles. Individuals with poorer mental health and a poorer personal lifestyle had higher neuroticism scores, and sex effects may influence the scale of perceived social support in the neuroticism group. However, the lack of an association between neuroticism score and metabolic syndrome may be due to the recruitment of younger participants in this study.

    Accurate assessment of CYP2D6 phenotypes from genotype is inadequate in patients taking CYP2D6 substrate together with CYP2D6 inhibitors. A novel CYP2D6 scoring system is proposed that incorporates the impact of concomitant medications with the genotype in calculating the CYP2D6 activity score. Training (n = 159) and validation (n = 81) data sets were obtained from a prospective cohort tamoxifen pharmacogenetics registry. Two inhibitor factors were defined: 1 genotype independent and 1 genotype based. Three CYP2D6 gene scoring systems, and their combination with the inhibitor factors, were compared. These 3 scores were based on Zineh, Zanger, and Gaedigk's approaches. Endoxifen/NDM-Tam plasma ratio was used as the phenotype. The overall performance of the 3 gene scoring systems without consideration of CYP2D6-inhibiting medications in predicting CYP2D6 phenotype was poor in both the training set (R(2) = 0.24, 0.22, and 0.18) and the validation set (R(2) = 0.30, 0.24, and 0.15). Once the CYP2D6 genotype-independent inhibitor factor was integrated into the score calculation, the R(2) values in the training and validation data sets were nearly twice as high as the genotype-only scoring model: (0.44, 0.43, 0.38) and (0.53, 0.50, 0.41), respectively. The integration of the inhibitory effect of concomitant medications with the CYP2D6 genotype into the composite CYP2D6 activity score doubled the ability to predict the CYP2D6 phenotype. However, endoxifen phenotypes still varied substantially, even with incorporation of CYD2D6 genotype and inhibiting factors, suggesting that other, as yet unidentified factors must be involved in tamoxifen activation.

    Analysis of the discrepancy between memory and intellectual ability has received some support as a means for evaluating memory impairment. Recently, comprehensive base rate tables for General Ability Index (GAI) minus memory discrepancy scores (i.e., GAI-memory) were developed using the WAIS-III/WMS-III standardization sample (Lange, Chelune, & Tulsky, in press). The purpose of this study was to evaluate the clinical utility of GAI-memory discrepancy scores to identify memory impairment in 34 patients with Alzheimer's type dementia (DAT) versus a sample of 34 demographically matched healthy participants. On average, patients with DAT obtained significantly lower scores on all WAIS-III and WMS-III indexes and had larger GAI-memory discrepancy scores. Clinical outcome analyses revealed that GAI-memory scores were useful at identifying memory impairment in patients with DAT versus matched healthy participants. However, GAI-memory discrepancy scores failed to provide unique interpretive information beyond that which is gained from the memory indexes alone. Implications and future research directions are discussed.

    Carotid intima-media thickness (cIMT) has been suggested as a further tool for risk function charts. The aim of this study was to describethe relationship between cIMT and cardiovascular risk (CVR) estimation according to Framingham-REGICOR and SCORE equations. Observational, cross-sectional cohort study from 362 hypertensive subjects. Demographic and clinical information were collected as well as laboratory, ultrasonographic and CVR estimation by the Framingham-REGICOR and SCORE functions. Statistical analysis was performed using SPSS software (version 20,0). To analyze the data, statistical tests such as Chi-square, T-test, ANOVA, and Pearson correlation coefficient were used. According to both functions, differences on mean cIMT were found between low CVR group and intermediate to high groups. No differences were found between intermediate and high risk groups (cIMT: 0,73mm low risk patients vs. 0,89 or 0,88mm respectively according to SCORE function and cIMT: 0,73 vs. 0,85 or 0,87mm respectively according to Framingham-REGICOR function). cIMT correlated positively with CVR estimation according to both SCORE (r=0,421; P<.01), and Framingham-REGICOR functions (r=0,363; P<.01). cIMT correlates positively with CVR estimated by SCORE and Framingham-REGICOR functions. cIMT in those subjects at intermediate risk is similar to those at high risk. Our findings highlight the importance of carotid ultrasound in identifying silent target-organ damage in those patients at intermediate CVR. Copyright © 2015 SEHLELHA.

  19. Psychosocial Care Needs of Melanoma Survivors: Are They Being Met?

    Directory of Open Access Journals (Sweden)

    Sabine Fischbeck

    Full Text Available Patients who have survived malignant melanoma for more than five years may lack the opportunity to talk about their burden. As a consequence their psychosocial care needs remain undetected and available supportive interventions may not be utilised. Therefore, the psychosocial burden of this patient group needs to be assessed using specific screening instruments. The aim of this study was to investigate the psychosocial burden of long-term melanoma survivors, their psychosocial care needs and the determinants of these needs. We wanted to find out if the use of professional support corresponds to the care needs defined by experts. Using the cancer registry of Rhineland-Palatinate, melanoma patients diagnosed at least 5 years before the survey were contacted by physicians. N = 689 former patients completed the Hornheide Questionnaire (short form HQ-S to identify psychosocial support need (scale cut off ≥ 16 or item-based cut-off score and the potential psychosocial determinants of these needs. Additionally, they were asked about their utilisation of the professional support system. More than one third (36% of them was in need for professional psychosocial support. The highest burden scores concerned worry about tumour progression. Younger age (< 50, higher general fatigue, higher symptom burden, lower general health, negative social interactions and unfulfilled information needs were significant predictors of the need for psychosocial intervention. Related to the percentage of survivors identified as 'in need', the professional support system was underused. Further studies should investigate whether using the HQ-S to routinely identify burdened melanoma patients could lead to better fulfilment of their intervention needs, ultimately enhancing health-related quality of life.

    Schizophrenia is a persistent, lifelong illness such that enduring functional improvements may only occur over the course of years [corrected].This post hoc analysis in stable outpatients with schizophrenia investigated the negative symptom efficacy and treatment outcomes of ziprasidone (80-160 mg/d given twice a day, mean modal dose of 112 mg/d; and 80-120 mg/d given every day, mean modal dose of 96 mg/d) versus haloperidol (5-20 mg/d, mean modal dose of 12 mg/d) in a randomized, 40-week, double-blind study, followed by a double-blind continuation trial that extended up to 156 additional weeks. Symptomatic and functional recovery criteria were met when subjects attained both negative symptom remission and adequate psychosocial functioning based on the 4 Quality-of-Life subscales (instrumental role, interpersonal relations, participation in community, and intrapsychic foundations). Negative symptom remission (P = 0.005), as well as sustained adequate functioning (6 months) in instrumental role (P = 0.04) and participation in community (P = 0.02), was associated with significantly shorter time to remission in the ziprasidone 80 to 160 mg group than in the haloperidol group, as was the combination of symptomatic and functional recovery during the 196-week double-blind study period. A similar pattern was observed for the ziprasidone 80 to 120 mg group, which showed significant differences versus haloperidol in negative symptom remission and instrumental role functioning (but not other Quality-of-Life subscale measures). The clinically relevant outcome differences detected in this post hoc exploratory analysis support the potential for both enhanced remission in negative symptoms and psychosocial recovery during long-term treatment with an atypical agent and add to our understanding regarding the degree to which negative symptom remission can be attained in the maintenance phase.

    The aim of this study was to explore the impact of ankylosing spondylitis (AS) and the disease-related variables on the patients' sexual function according to the International Index of Erectile Function (IIEF) scoring system. A total of 70 sexually active male AS patients and 60 healthy controls were enrolled in this study. Their demographic data were evaluated, and the pain was assessed according to the visual analogue scale (VAS). Laboratory tests were conducted in order to measure the C-reactive protein (CRP) and erythrocyte sedimentation rates (ESR) of the patients. The disease activity was evaluated using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Functional statement was evaluated with the help of the Bath Ankylosing Spondylitis Functional Index (BASFI) and with the scores obtained from the spinal measurements with the Bath Ankylosing Spondylitis Metrology Index (BASMI). The Bath Ankylosing Spondylitis Radiology Index (BASRI) was used to evaluate the radiological damage. The disease-related quality of life was measured with the Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL). The anxiety and depression level of the patients was revealed through the Hospital Anxiety and Depression Scale (HADS). In comparison with the healthy control group, patients with AS had significantly lower scores in each of the 5 domains of the IIEF (p function and sexual desire scores were significantly lower in patients with peripheral arthritis (p sexual function. The sexual function is impaired in male patients with AS. This impairment in the sexual function is especially correlated with the BASFI and BASMI among the clinical and laboratory parameters.

    Full Text Available Objective: The aim of this study is to present a comprehensive profile of clinical and psychosocial characteristics of children with psychogenic nonepileptic seizures and to assess the short-term outcome of these patients. Materials and Methods: The subjects were consecutive cases of children with a diagnosis of nonepileptic seizures (N=17, mean age = 10.7 years, S.D. = 1.26 and two groups of control groups matched on age and sex: true seizure group and healthy controls. All the children were recruited from the out-patient services of the Department of Pediatrics of a tertiary care teaching hospital in North India. Detailed history taking and clinical examination was done in the case of every child. A standard 18 channel EEG was done in all the children and a video EEG was done in 12 cases of children with nonepileptic seizures. The Childhood Psychopathology Measurement Schedule (CPMS and Life Events Scale for Indian Children (LESIC were used to measure the children′s emotional and behavioral functioning at home, and the number of life events and the stress associated with these events in the preceding year and the year before that. Short-term outcome was examined three to six months after the diagnosis of nonepileptic seizures was made. Results: Unresponsiveness without marked motor manifestations was the most common "ictal" characteristic of the nonepileptic seizures. Pelvic thrusting, upper and lower limb movements, head movements, and vocalization were observed in less than one-third of the patients. Increased psychosocial stress and significantly higher number of life events in the preceding year were found to characterize children with nonepileptic seizures, as compared to the two control groups. The nonepileptic seizures and true seizures groups had a higher proportion of children with psychopathology scores in the clinically significant maladjustment range, as compared to those in the healthy control group. A majority of the patients

We assessed the clinical outcomes of dorsal release of the first extensor compartment for the treatment of de Quervain's disease using the disabilities of the arm, shoulder and hand (DASH) score. Methods From October 2003 to May 2009, we retrospectively evaluated 33 patients (3 men and 30 women) who underwent surgical treatment for de Quervain's disease. All patients had a positive Finkelstein test and localized tenderness over the first dorsal compartment. All operations were performed under local anesthesia. A 2-cm-long transverse skin incision was made over the first extensor compartment and the dorsal retinaculum covering the extensor pollicis brevis was incised longitudinally. Preoperative and postoperative clinical evaluation included the use of DASH score, Finkelstein test, and visual analogue scale (VAS) score. Results In 18 patients (55%), the extensor pollicis brevis tendon compartment was separated from the abductor pollicis longus compartment. Eight patients had intracompartmental ganglia in the extensor pollicis brevis subcompartment. All patients except one had negative sign on Finkelstein test at the last follow-up. The average VAS score decreased from 7.42 preoperatively to 1.33 postoperatively (p Quervain's disease. The release of the first extensor compartment for refractory de Quervain's disease resulted in good clinical outcomes with minimal morbidity. PMID:25436064

    Forty-three children between the ages of 6 and 13 years with congenital facial anomalies underwent psychosocial evaluation prior to surgery. Also evaluated were healthy children matched to the craniofacial subjects by sex, age, intelligence, and economic background. Relative to this comparison group, the craniofacial children were found to have poorer self-concept, greater anxiety at the time of evaluation, and more introversion. Parents of the craniofacial children noted more frequent negative social encounters for their children and more hyperactive behavior at home. Teachers reported more problematic classroom behavior. Examination of these results revealed craniofacial malformations to be associated with psychosocial limitations rather than marked deficits. These children tended to function less well than the comparison children, but with few exceptions, they were not functioning in a psychosocially deviant range. Explanations for the observed circumscribed impact of facial deformity include the use of denial as a coping mechanism, possible diminished significance of appearance for younger children, and the restricted environment experienced by most of the subjects. It can be predicted that time would render these protective influences ineffective, so that adolescent and young adult patients could be at far greater psychosocial risk.

    Full Text Available Abstract Background Recent advances on high-throughput technologies have produced a vast amount of protein sequences, while the number of high-resolution structures has seen a limited increase. This has impelled the production of many strategies to built protein structures from its sequence, generating a considerable amount of alternative models. The selection of the closest model to the native conformation has thus become crucial for structure prediction. Several methods have been developed to score protein models by energies, knowledge-based potentials and combination of both. Results Here, we present and demonstrate a theory to split the knowledge-based potentials in scoring terms biologically meaningful and to combine them in new scores to predict near-native structures. Our strategy allows circumventing the problem of defining the reference state. In this approach we give the proof for a simple and linear application that can be further improved by optimizing the combination of Zscores. Using the simplest composite score ( we obtained predictions similar to state-of-the-art methods. Besides, our approach has the advantage of identifying the most relevant terms involved in the stability of the protein structure. Finally, we also use the composite Zscores to assess the conformation of models and to detect local errors. Conclusion We have introduced a method to split knowledge-based potentials and to solve the problem of defining a reference state. The new scores have detected near-native structures as accurately as state-of-art methods and have been successful to identify wrongly modeled regions of many near-native conformations.

    It is increasingly necessary that pediatricians have greater knowledge of adolescent health. To begin with they should be familiar with the psychosocial development of this period, an issue which is imperative for the health care of the age group. With that purpose, this article reviews the normal adolescent psychosocial development. Adolescence is a stage that has been progressively prolonged, during which fast and big changes occur, that lead human beings to become biologically, psychologically and socially mature, and potentially able to live independently. Developmental tasks of this period are the establishment of identity and the achievement of autonomy. Although it is a process of high individual variability in terms of its beginning and end, the progression through stages, the synchrony of development between the various areas, and in other aspects, the psychosocial development of this period usually have common characteristics and a progressive pattern of 3 phases: early, middle and late adolescence. Psychological, cognitive, social, sexual and moral development of young people in each of them are described in this article. Copyright © 2015 Sociedad Chilena de Pediatría.

    Full Text Available Innovation in assisted reproductive technologies together with increased infertility and new family structures are increasing the use of gestational surrogacy as a means to have children. Before, during and after the process, it is necessary to study the psychosocial characteristics of triad members: the gestational surrogate, intended parents, and offspring. Research has indicated positive adaptation to the process and benefits for all members of the triad. Altruism is the main motivation of surrogates. Notably, psychological well-being has been found to be higher in individuals who have become parents through surrogacy than in those who have used egg donation or have followed a natural process of conception. Moreover, no differences in psychosocial characteristics have been observed in the offspring, compared with children born through natural conception or egg donation. Results highlight the positive aspects of surrogacy. Future research should investigate psychosocial factors that modulate the process, acting as risk and protective factors for well-being of the triad members, and identify the optimal profiles of surrogates for the process to be a success.

    Full Text Available Background: The effects of treatment in trials with trauma-affected refugees vary considerably not only between studies but also between patients within a single study. However, we know little about why some patients benefit more from treatment, as few studies have analysed predictors of treatment outcome. Objective: The objective of the study was to examine possible psychosocial predictors of treatment outcome for trauma-affected refugees. Method: The participants were 195 adult refugees with posttraumatic stress disorder (PTSD who were enrolled in a 6- to 7-month treatment programme at the Competence Centre for Transcultural Psychiatry (CTP, Denmark. The CTP Predictor Index used in the study included 15 different possible outcome predictors concerning the patients’ past, chronicity of mental health problems, pain, treatment motivation, prerequisites for engaging in psychotherapy, and social situation. The primary outcome measure was PTSD symptoms measured on the Harvard Trauma Questionnaire (HTQ. Other outcome measures included the Hopkins Symptom Check List-25, the WHO-5 Well-being Index, Sheehan Disability Scale, Hamilton Depression and Anxiety Scales, the somatisation scale of the Symptoms Checklist-90, Global Assessment of Functioning scales, and pain rated on visual analogue scales. The relations between treatment outcomes and the total score as well as subscores of the CTP Predictor Index were analysed. Results: Overall, the total score of the CTP Predictor Index was significantly correlated to pre- to post treatment score changes on the majority of the ratings mentioned above. While employment status was the only single item significantly correlated to HTQ-score changes, a number of single items from the CTP Predictor Index correlated significantly with changes in depression and anxiety symptoms, but the size of the correlation coefficients were modest. Conclusions: The total score of the CTP Predictor Index correlated significantly

    To evaluate the effect of culturally-relevant food supplementation and psychosocial stimulation on infant growth and development. A community-based randomized controlled trial was conducted in 40 clusters from 5 selected villages in Tanah Datar District of West Sumatera, Indonesia. We assessed 355 infants aged 6 to 9 months at the beginning of the study. The infants were divided into 4 groups: 1) Food Supplementation (FS); 2) Psychosocial Stimulation (PS); 3) Food Supplementation and Psychosocial Stimulation (FS+PS); and 4) Control Group (CG). The formula food supplement was comprised of a variety of local food sources (local MP-ASI) and adjusted for the local habits. The quality of psychosocial stimulation was assessed with the Infant HOME inventory method. Progress at 6 months was assessed by anthropometry and the Bayley scores of cognition, language and motor function. There were improvements in linear growth, cognitive and motor development of children in the FS (pcognitive development increased to 21.4±12.2 points (effect size 0.56) (pdevelopment increased to 20.7±18.4 points (effect size 0.50) (pcognitive and motor development.

    Aim: Although warfarin remains important despite the widespread use of nonvitamin K antagonist oral anticoagulants (NOACs), to date, the reality of warfarin use in the “NOACs era” is unclear. This multicenter observational study aimed to clarify the key factors contributing to warfarin treatment stability. Methods: The practical use of warfarin, stability of warfarin therapy, and factors contributing to this stability were investigated in community-based hospitals through a real-world study. Clinical data were retrospectively extracted from the medical records of warfarin-treated Japanese patients (age, 71.3 ± 5.5 years) with atrial fibrillation (AF), prosthetic heart valve, or other concerns requiring anticoagulation. Treatment stability was considered as time in therapeutic range of international normalized ratio of prothrombin time (TTR: %). The factors contributing to TTR were investigated, including CHADS2 score components. Results: Mean CHADS2 score was highest (1.38 ± 0.88, p antiplatelet agents did not correlate with the low TTR. Conclusions: This retrospective study demonstrated that the CHADS2 score component accumulation and hepatorenal dysfunction are factors significantly contributing to the low TTR, which is indicative of poor warfarin treatment stability, in patients such as those with AF.

    Precise thermodynamic integration free energy simulations have been applied to a congeneric series of 16 inhibitors to the p38 MAP kinase protein for which the experimental binding data (IC(50)) is known. The relative free energy of binding for each compound has been determined. For comparison, the same series of compounds have also scored using the best rapid scoring functions used in database screening. From the results of these calculations, we find (1) that precise free energy simulations allow predictions that are reliable and in good agreement with experiment; (2) that predictions of lower reliability, but still in good qualitative agreement with experiment, can be obtained using the OWFEG free energy grid method, at a much lower computational cost; (3) and that other methods, not based on free energy simulations yield results in much poorer agreement with experiment. A new predictive index, which measures the reliability of a prediction method in the context of normal use, is defined and calculated for each scoring method. Predictive indices of 0.84, 0.56, 0.04, -0.05, and 0.25 are calculated for thermodynamic integration, OWFEG, ChemScore, PLPScore, and Dock Energy Score, respectively, where +1.0 is perfect correct prediction, -1.0 is perfect incorrect prediction, and 0.0 is random.

    Availability of energy functions which can discriminate native-like from non-native protein conformations is crucial for theoretical protein structure prediction and refinement of low-resolution protein models. This article reports the results of benchmark tests for scoring functions based on two all-atom ECEPP force fields, that is, ECEPP/3 and ECEPP05, and two implicit solvent models for a large set of protein decoys. The following three scoring functions are considered: (i) ECEPP05 plus a solvent-accessible surface area model with the parameters optimized with a set of protein decoys (ECEPP05/SA); (ii) ECEPP/3 plus the solvent-accessible surface area model of Ooi et al. (Proc Natl Acad Sci USA 1987;84:3086-3090) (ECEPP3/OONS); and (iii) ECEPP05 plus an implicit solvent model based on a solution of the Poisson equation with an optimized Fast Adaptive Multigrid Boundary Element (FAMBEpH) method (ECEPP05/FAMBEpH). Short Monte Carlo-with-Minimization (MCM) simulations, following local energy minimization, are used as a scoring method with ECEPP05/SA and ECEPP3/OONS potentials, whereas energy calculation is used with ECEPP05/FAMBEpH. The performance of each scoring function is evaluated by examining its ability to distinguish between native-like and non-native protein structures. The results of the tests show that the new ECEPP05/SA scoring function represents a significant improvement over the earlier ECEPP3/OONS version of the force field. Thus, it is able to rank native-like structures with C(alpha) root-mean-square-deviations below 3.5 A as lowest-energy conformations for 76% and within the top 10 for 87% of the proteins tested, compared with 69 and 80%, respectively, for ECEPP3/OONS. The use of the FAMBEpH solvation model, which provides a more accurate description of the protein-solvent interactions, improves the discriminative ability of the scoring function to 89%. All failed tests in which the native-like structures cannot be discriminated as those with low

    Background Orthognathic surgery is a branch of maxillofacial surgery. It carries out the treatment of the facial skeleton asymmetries and deformities. The patients who ask for this surgery are often young people who usually refer symptoms related to dental malocclusion, difficulty eating and temporo-mandibular pain. These physical symptoms are often accompanied by psychological symptoms triggered by their physical appearance such as low self-esteem, self-confidence and negativism about their social and emotional future. Material and Methods Patients with skeletal malformation of facial bones, consisting in Class II, III, open bite and asymmetries, underwent to orthognathic surgery in our center agreed to participate voluntarily in this study. They answered a questionnaire regarding several psychosocial variables. Results Orthognathic surgery helps to improve patient’s psychosocial well-being. Conclusions Patients with dentofacial deformitiesexperience physical and psychological, oftentimes underestimated by society. A combination of orthodontic treatment and reconstructive surgery is often a necessity to restore function and psychosocial well-being. Key words:Orthogathic surgery, psychosocial consequences, mood, emotions, sense of power, motivation, satisfaction, social changes, satisfaction. PMID:27957267

    Data on the psychosocial burden of human papillomavirus (HPV)-related diseases other than cervical cancer are scarce. The objectives of this study were to measure and compare the psychosocial burden and the impact on health-related quality of life (HRQoL) of HPV-related lower genital tract diseases and genital warts (GW) using several generic and disease-specific instruments. Overall, 842 individuals with normal cervical cytology (n = 241), borderline nuclear abnormalities and/or mild dyskaryosis (n = 23), cervical intraepithelial neoplasia (CIN)1 (n = 84), CIN2/3 (n = 203), vulval intraepithelial neoplasia (VIN)2/3 (n = 43), GW (n = 186) and a history of GW (non-current) (n = 62) were included. The generic European Quality of Life Index Version 5D (EQ-5D) questionnaire was completed by patients with GW and VIN2/3. Sexual functioning was evaluated using the Change in Sexual Functioning Questionnaire (CSFQ). Psychosocial impact was measured in women using the HPV Impact Profile (HIP) questionnaire. HRQoL was assessed using a GW-specific questionnaire, the Cuestionario Especifico en Condilomas Acuminados (CECA) (completed by patients with GW and history of GW). For each instrument, scores were compared between groups using the Student's t-test. In addition, utility loss due to GW and VIN2/3 was evaluated by comparing mean EQ-5D scores weighted by age and sex with the UK general population normal values. A significant psychosocial impact was found in women diagnosed with HPV-related genital diseases, particularly in those with GW. The health state of younger adults with GW was significantly impaired compared with UK normal values (mean EQ-5D index score 0.86 vs 0.94, p HPV-related lower genital tract lesions and GW significantly impair psychosocial wellbeing and HRQoL. The psychosocial aspects of HPV-related diseases need to be considered when evaluating the potential benefit of HPV vaccination.

    Full Text Available BACKGROUND: Premature ejaculation (PE is a very common sexual dysfunction among patients, and with varying prevalence estimates ranging from 3% to 20%. Although psychological issues are present in most patients with premature PE, as a cause or as a consequence, research on the effects of psychological approaches for PE has in general not been controlled or randomised and is lacking in long-term follow up. OBJECTIVE: To assess the efficacy of psychosocial interventions for PE. CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: Trials were searched in computerized general and specialized databases, such as: MEDLINE by PubMed (1966 to 2010; PsycINFO (1974 to 2010; EMBASE (1980 to 2010; LILACS (1982 to 2010; the Cochrane Central Register of Controlled Trials (Cochrane Library, 2010; and by checking bibliographies, and contacting manufacturers and researchers. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials evaluating psychosocial interventions compared with different psychosocial interventions, pharmacological interventions, waiting list, or no treatment for PE. DATA COLLECTION AND ANALYSIS: Information on patients, interventions, and outcomes was extracted by at least two independent reviewers using a standard form. The primary outcome measure for comparing the effects of psychosocial interventions to waiting list and standard medications was improvement in IELT (i.e., time from vaginal penetration to ejaculation. The secondary outcome was change in validated PE questionnaires. MAIN RESULTS: In one study behavioral therapy (BT was significantly better than waiting list for duration of intercourse (MD (mean difference 407.90 seconds, 95% CI 302.42 to 513.38, and couples' sexual satisfaction (MD -26.10, CI -50.48 to -1.72.

    Long-term acute care hospitals (LTACHs) have emerged for patients requiring medical care beyond a short stay. Minimal data have been reported on functional outcomes in this setting. The purposes of this study were: (1) to measure the clinical utility of the Functional Status Score for the Intensive Care Unit (FSS-ICU) in an LTACH setting and (2) to explore the association between FSS-ICU score and discharge setting. Data were obtained from 101 patients (median age=70 years, interquartile range [IQR]=61-78; 39% female, 61% male) who were admitted to an LTACH. Participants were categorized into 1 of 5 groups by discharge setting: (1) home (n=14), (2) inpatient rehabilitation facility (n=26), (3) skilled nursing facility (n=23), (4) long-term care/hospice/expired (n=13), or (5) transferred to a short-stay hospital (n=25). Data were prospectively collected from a 38-bed LTACH in the United States over 8 months beginning in September 2010. Functional status was scored using the FSS-ICU within 4 days of admission and every 2 weeks until discharge. The FSS-ICU consists of 5 categories: rolling, supine-to-sit transfers, unsupported sitting, sit-to-stand transfers, and ambulation. Each category was rated from 0 to 7, with a maximum cumulative FSS-ICU score of 35. Cumulative FSS-ICU scores significantly improved from a median (IQR) of 9 (3-17) to 14 (5-24) at discharge. Median (IQR) cumulative discharge FSS-ICU scores were significantly different among the discharge categories: home=28 (22-32), inpatient rehabilitation facility=21 (15-24), skilled nursing facility=14 (8-21), long-term care/hospice/expired=5 (0-11), and transfer to a short-stay hospital=4 (0-7). Patients receiving therapy at an LTACH demonstrate significant improvements from admission to discharge using the FSS-ICU. This outcome tool discriminates among discharge settings and successfully documents functional improvements of patients in an LTACH setting.

    Social attitudes towards epilepsy cause more distress to the patient and his/her near and dear ones, than the disease itself. The major psychosocial issues related to epilepsy are: Quality of medical management, overprotection, education, employment, marriage and pregnancy. Inadequate treatment is the major reason involved in psychosocial issues. Constant overprotection and pampering leads to behavioural pattern which makes epileptic patient dependent for ever. Education is hampered in epileptic persons. Teachers and students should have proper information regarding seizures. If seizures are well controlled, job opportunities increase. Employers and employees need to be educated about epilepsy. Self-employment is the best in epileptic patients. Regarding marriage, each patient is to be judged on individual merits and type of epilepsy. Society needs to be educated about the facts and consequences of epilepsy. Risk of anti-epileptic drug's usage is very insignificant compared to risk of seizures in pregnancy. So girls are advised to seek medical advice before pregnancy and during follow-up. With more and more support from the society, persons with epilepsy will have the courage and confidence to speak about themselves and their illness. It is only then that we will realise that persons with epilepsy are 'normal' or 'near-normal' and this will break the vicious cycle of stigma.

    The purpose of this study was to investigate predictors of bleeding in a cohort of anticoagulated patients and to evaluate the predictive value of several bleeding risk stratification schemas. The risk of bleeding during antithrombotic therapy in patients with atrial fibrillation (AF) is not homogeneous, and several clinical risk factors have been incorporated into clinical bleeding risk stratification schemas. Current risk stratification schemas for bleeding during anticoagulation therapy have been based on complex scoring systems that are difficult to apply in clinical practice, and few have been derived and validated in AF cohorts. We investigated predictors of bleeding in a cohort of 7,329 patients with AF participating in the SPORTIF (Stroke Prevention Using an ORal Thrombin Inhibitor in Atrial Fibrillation) III and V clinical trials and evaluated the predictive value of several risk stratification schemas by multivariate analysis. Patients were anticoagulated orally with either adjusted-dose warfarin (target international normalized ratio 2 to 3) or fixed-dose ximelagatran 36 mg twice daily. Major bleeding was centrally adjudicated, and concurrent aspirin therapy was allowed in patients with clinical atherosclerosis. By multivariate analyses, significant predictors of bleeding were concurrent aspirin use (hazard ratio [HR]: 2.10; 95% confidence interval [CI]: 1.59 to 2.77; p HR: 1.98; 95% CI: 1.42 to 2.76; p HR: 1.63; 95% CI: 1.23 to 2.17; p = 0.0008); diabetes (HR: 1.47; 95% CI: 1.10 to 1.97; p = 0.009), and heart failure or left ventricular dysfunction (HR: 1.32; 95% CI: 1.01 to 1.73; p = 0.041). Of the tested schemas, the new HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol Concomitantly) score performed best, with a stepwise increase in rates of major bleeding with increasing HAS-BLED score (p(trend) <0.0001). The c statistic for bleeding varied between 0.50 and 0.67 in

    Pre-clinical evidence indicates that autologous bone marrow-derived mesenchymal stromal cell (BM-MSC) transplantation improves motor function in patients with central nervous system disorders. After providing informed consent, 52 patients with cerebral palsy (CP) who met the study criteria received BM-MSC transplantation. Gross motor function was assessed using the Gross Motor Function Measure (GMFM)-88 and GMFM-66 scales at baseline (before transplantation) and at 1 month, 6 months and 18 months post-transplantation. The participants completed the trial without visible side effects. The GMFM-66 percentile (motor growth curves) was used as the control index of motor function to exclude the interference of improvement with age. The score domains A, B, C and D and the total GMFM-88 and GMFM-66 scores in participants increased at 1 month, 6 months and 18 months post-transplantation compared with the baseline value (P cell transplantation. Autologous BM-MSC transplantation appears to be a feasible, safe and effective therapy for patients with CP. The treatment improved the development of children with CP with regard to motor function.

    Anxiety disorders are associated with adverse psychosocial functioning, and are predictive of a wide range of psychiatric disorders in adulthood. The present study examined the associations between anxiety disorders during childhood and adolescence and psychosocial outcomes at age 30, and sought to address the extent to which psychopathology after age 19 mediated these relations. Eight hundred and sixteen participants from a large community sample were interviewed twice during adolescence, at age 24, and at age 30. They completed self-report measures of psychosocial functioning and semi-structured diagnostic interviews during adolescence and young adulthood. Adolescent anxiety predicted poor total adjustment, poor adjustment at work, poor family relationships, problems with the family unit, less life satisfaction, poor coping skills, and more chronic stress. Adolescent anxiety predicted, substance (SUD), alcohol abuse/dependence (AUD), and anxiety in adulthood. No adult psychopathology mediated the relationship between childhood anxiety disorders and psychosocial outcomes at age 30. Adult, SUD, AUD and anxiety mediated the association between adolescent anxiety and most domains of psychosocial functioning at age 30. The participants are ethically and geographically homogenous, and changes in the diagnostic criteria and the interview schedules across the assessment periods. Adolescent anxiety, compared to childhood anxiety, is associated with more adverse psychosocial outcomes at age 30. Adolescent anxiety affects negative outcomes at age 30 directly and through adult anxiety, SUD and AUD. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Hospital readmission for acute exacerbation of COPD (AECOPD occurs in up to 30% of patients, leading to excess morbidity and poor survival. Physiological risk factors predict readmission, but the impact of modifiable psychosocial risk factors remains uncertain. We aimed to evaluate whether psychosocial risk factors independently predict readmission for AECOPD in patients referred to early discharge services (EDS. Methods This prospective cohort study included 79 patients with AECOPD cared for by nurse led EDS in the UK, and followed up for 12 months. Data on lung function, medical comorbidities, previous hospital admissions, medications, and sociodemographics were collected at baseline; St George's Respiratory Questionnaire (SGRQ, Hospital Anxiety and Depression Scale (HADS, and social support were measured at baseline, 3 and 12-months. Exploratory multivariate models were fitted to identify psychosocial factors associated with readmission adjusted for known confounders. Results 26 patients were readmitted within 90 days and 60 patients were readmitted at least once during follow-up. Depression at baseline predicted readmission adjusted for sociodemographics and forced expiratory volume in 1 second (odds ratio 1.30, 95% CI 1.06 to 1.60, p = 0.013. Perceived social support was not significantly associated with risk of readmission. Home ownership was associated with the total number of readmissions (B = 0.46, 95% CI -0.86 to -0.06, p = 0.024. Compared with those not readmitted, readmitted patients had worse SGRQ and HADS scores at 12 months. Conclusion Depressive symptoms and socioeconomic status, but not perceived social support, predict risk of readmission and readmission frequency for AECOPD in patients cared for by nurse-led EDS. Future work on reducing demand for unscheduled hospital admissions could include the design and evaluation of interventions aimed at optimising the psychosocial care of AECOPD patients managed at

    Previous research has demonstrated an association between the emotional and behavioral symptoms of dementia, known as neuropsychiatric symptoms, and cognitive and functional decline among patients with Alzheimer disease (AD). The present study aimed to identify associations between neuropsychiatric symptoms as measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q) and cognitive and functional performance. Participants were 256 AD patients enrolled in the Alzheimer's Disease and Memory Disorders Center at Baylor College of Medicine. An exploratory factor analysis of the NPI-Q indicated a 2-factor structure consisting of Negative/Oppositional and Anxiety/Restlessness factors. Regression analyses revealed significant associations between greater total severity of neuropsychiatric symptoms and poorer performance on basic and Instrumental Activities of Daily Living. Greater severity of Anxiety/Restlessness symptoms was associated with poor performance on measures of visuospatial functioning and basic and instrumental activities of daily living. The Negative/Oppositional factor was not related to cognition or functioning. In summary, neuropsychiatric symptoms (particularly Anxiety/Restlessness symptoms) were related to cognition and everyday functioning. Proper assessment and treatment of these symptoms is essential for improving cognition and functioning in AD patients.

    In determining patient satisfaction with functional and aesthetic outcome after reconstructive surgery, including nasal reconstruction, standardised assessment instruments are very important. These standardised tools are needed to adequately evaluate and compare outcome results. Since no such instrument existed for nasal reconstruction, a standardised evaluation questionnaire was developed to assess aesthetic and functional outcome after nasal reconstruction. Items of the Nasal Appearance and Function Evaluation Questionnaire (NAFEQ) were derived from both the literature and experiences with patients. The NAFEQ was validated on 30 nasal reconstruction patients and a reference group of 175 people. A factor analysis confirmed the arrangement of the questionnaire in two subscales: functional and aesthetic outcome. High Cronbach's alpha values (>0.70) for both subscales showed that the NAFEQ was an internally consistent instrument. This study demonstrated that the NAFEQ can be used as a standardised questionnaire for detailed evaluation of aesthetic and functional outcome after nasal reconstruction. Its widespread use would enable comparison of results achieved by different techniques, surgeons and centres in a standardised fashion.

    2016-08-01

    Asthma is the most common chronic illness among children in the United States and can impact nearly all aspects of functioning. Most research suggests that children with severe asthma display more emotional and behavioral problems than their healthy peers. These psychological difficulties are associated with increased risk for functional impairments and problematic disease course. Multidisciplinary teams that assess and treat these psychosocial factors using psychoeducational and behavioral interventions are important for children whose asthma is poorly controlled. Future research should examine the ways in which stress, emotions, and immune functions interact, so as to develop more preventative interventions.

    1998-01-01

    Previous research has suggested that links between autonomic nervous system functioning and violence are strongest in those who come from benign home backgrounds, but there appears to be no similar research using brain-imaging measures of central nervous system functioning. It was hypothesized that murderers who had no early psychosocial deprivation (e.g., no childhood abuse, family neglect) would demonstrate lower prefrontal glucose metabolism than murderers with early psychosocial deprivation and a group of normal controls. Murderers from a previous study, which showed prefrontal deficits in murderers, were assessed for psychosocial deprivation and divided into those with and without deprivation. Murderers without any clear psychosocial deficits were significantly lower on prefrontal glucose metabolism than murderers with psychosocial deficits and controls. These results suggest that murderers lacking psychosocial deficits are characterized by prefrontal deficits. It is argued that among violent offenders without deprived home backgrounds, the "social push" to violence is minimized, and consequently, brain abnormalities provide a relatively stronger predisposition to violence in this group.

    Full Text Available Background: Functional national laboratory networks and systems are indispensable to the achievement of global health security targets according to the International Health Regulations. The lack of indicators to measure the functionality of national laboratory network has limited the efficiency of past and current interventions to enhance laboratory capacity in resourcelimited-settings.Scorecard for laboratory networks: We have developed a matrix for the assessment of national laboratory network functionality and progress thereof, with support from the African Society of Laboratory Medicine and the Association of Public Health Laboratories. The laboratory network (LABNET scorecard was designed to: (1 Measure the status of nine overarching core capabilities of laboratory network required to achieve global health security targets, as recommended by the main normative standards; (2 Complement the World Health Organization joint external evaluation tool for the assessment of health system preparedness to International Health Regulations (2005 by providing detailed information on laboratory systems; and (3 Serve as a clear roadmap to guide the stepwise implementation of laboratory capability to prevent, detect and act upon infectious threats.Conclusions: The application of the LABNET scorecard under the coordination of the African Society of Laboratory Medicine and the Association of Public Health Laboratories could contribute to the design, monitoring and evaluation of upcoming Global Health Security Agenda-supported laboratory capacity building programmes in sub Saharan-Africa and other resource-limited settings, and inform the development of national laboratory policies and strategic plans. Endorsement by the World Health Organization Regional Office for Africa is foreseen.

    Müller, D

    1999-01-01

    This article argues for incorporating psychosocial adjustment into treatment plans for people with aphasia. It proposes that rehabilitation is a social rather than a medical construct and that by adopting a broad range of intervention strategies, more effective approaches to reintegration can be adopted. Outcome measures relating to self-esteem are judged to be central to evaluating the efficacy of treatment. The role of social factors in managing psychosocial adjustment are considered alongside individual and family approaches to counseling. It is concluded that clinicians need to broaden their treatment program to include psychosocial adjustment in rehabilitation.

    The amount of irreversible injury on renal allograft biopsy predicts function, but little is known about the early evolution of this damage. In a single-center cohort, we examined the relationship between donor-, recipient-, and transplantation-associated factors and change in a morphometric index of chronic damage (ICD) between protocol biopsies performed at implantation and at 2-3 months. We then investigated whether early delta ICD predicted subsequent biochemical outcomes. We found little evidence to support differences between the study group, who had undergone serial biopsies, and a contemporaneous control group, who had not. In allografts with serial biopsies (n = 162), there was an increase in ICD between implantation (median: 2%, IQR:0-8) and 2-3 months post-transplant (median 8% IQR:4-15; p live donors was independently associated with smaller early post-transplant increases in ICD. There was no evidence for a difference in delta ICD between donation after cardiac death vs. donation after brain death, nor association with length of cold ischemia. After adjustment for GFR at the time of the second biopsy, delta ICD after three months did not predict allograft function at one yr. These findings suggest that graft damage develops shortly after transplantation and reflects donor factors, but does not predict future biochemical outcomes.

  8. On the necessity of dissecting sequence similarity scores into segment-specific contributions for inferring protein homology, function prediction and annotation.

    Wong, Wing-Cheong; Maurer-Stroh, Sebastian; Eisenhaber, Birgit; Eisenhaber, Frank

    2014-06-02

    Protein sequence similarities to any types of non-globular segments (coiled coils, low complexity regions, transmembrane regions, long loops, etc. where either positional sequence conservation is the result of a very simple, physically induced pattern or rather integral sequence properties are critical) are pertinent sources for mistaken homologies. Regretfully, these considerations regularly escape attention in large-scale annotation studies since, often, there is no substitute to manual handling of these cases. Quantitative criteria are required to suppress events of function annotation transfer as a result of false homology assignments. The sequence homology concept is based on the similarity comparison between the structural elements, the basic building blocks for conferring the overall fold of a protein. We propose to dissect the total similarity score into fold-critical and other, remaining contributions and suggest that, for a valid homology statement, the fold-relevant score contribution should at least be significant on its own. As part of the article, we provide the DissectHMMER software program for dissecting HMMER2/3 scores into segment-specific contributions. We show that DissectHMMER reproduces HMMER2/3 scores with sufficient accuracy and that it is useful in automated decisions about homology for instructive sequence examples. To generalize the dissection concept for cases without 3D structural information, we find that a dissection based on alignment quality is an appropriate surrogate. The approach was applied to a large-scale study of SMART and PFAM domains in the space of seed sequences and in the space of UniProt/SwissProt. Sequence similarity core dissection with regard to fold-critical and other contributions systematically suppresses false hits and, additionally, recovers previously obscured homology relationships such as the one between aquaporins and formate/nitrite transporters that, so far, was only supported by structure comparison.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent, chronic pelvic pain condition largely unresponsive to medical interventions. Psychosocial risk factors are associated with poor outcomes in CP/CPPS, but have not been examined for their intervening roles between pain and reduced quality of life (QoL). This study aimed to determine if psychosocial risk factors (i.e., patient coping and catastrophizing) mediate the association between pain and QoL. Using a cross sectional design, 175 men with CP/CPPS (mean age 46.83; SD 10.86) were recruited from tertiary care urology clinics and completed questionnaires on demographics, pain, QoL, pain coping, depression, and catastrophizing. An exploratory factor analysis was conducted and aggregate factor scores were examined to improve the amount of meaningful measurement to be used in multiple mediations. The models specified multiple risk factors as mechanisms between pain and both physical and mental QoL as the primary outcome measurements. Four aggregate psychosocial factor scores were produced from the psychosocial measures (i.e., illness and wellness-focused behavioural coping, depression and catastrophizing). Illness-focused coping partially mediated the relationship between pain and physical QoL. However, catastrophizing and illness-focused coping fully mediated the relation between pain and mental QoL, showing the association between pain and mental QoL was no longer significant when catastrophizing and illness-focused coping were in the model. Psychosocial factors function as mechanisms between higher pain and they are associated diminished mental QoL. These results introduce illness-focused coping as an important biopsychosocial target in CP/CPPS management.

    Full Text Available Purpose: To compare the psychosocial status before and after successful strabismus surgery on Iranian strabismic patientsMethods: One hundred twenty-four strabismic patients, older than 15 years were evaluated between 2009 and 2010. They were asked to complete a questionnaire about their psychosocial experiences, before and three months after successful strabismus surgery. Effects of strabismus on self-esteem, self-confidence, and self-assessment of intelligence, employment and interpersonal relationships were compared.Results: Fifty-six percent of patients had problems in adjusting to society, and 71% had developed a mannerism to camouflage their misalignment before surgery. The preoperative scores of self-esteem, self-confidence, and interpersonal relationship were 4.33±2.07, 4.23±2.53 and 6.06±2.33 which changed to 8.33±3.02, 7.29±2.89 and 6.72±3.17 after surgery, respectively (p<0.001 for all of values. More esotropic patients reported to be discriminated against compared to exotropic patients. Postoperatively, 79% of patients reported improvements in their ability to meet new people, and 82% in interpersonal relationships. Scores of self-confidence and self-esteem increased up to three and four units, respectively (p<0.001 for both values.Conclusion: Patients with strabismus have psychosocial problems and successful strabismus surgery improves their psychosocial status.

  12. Cell phones: the psychosocial risks.

    Sansone, Randy A; Sansone, Lori A

    2013-01-01

    Cell phones are a relatively novel and evolving technology. While the potential benefits of this technology continue to emerge, so do the potential psychosocial risks. For example, one psychosocial risk is user stress, which appears to be related to feeling compelled to promptly respond to cell-phone activity in order to maintain spontaneity and access with others. Other potential psychosocial risks include disruptions in sleep; the user's risk of exposure to cyberbullying, particularly the unwanted exposure of photographs and/or videos of the victim; and overuse, particularly among adolescents. With regard to the latter phenomenon, the boundaries among overuse, misuse, dependence, and addiction are not scientifically clear. Therefore, while cell phones are a convenient and expedient technology, they are not without their potential psychosocial hazards.

    Full Text Available Objectives. (1 To develop two independent measurement scales for use as items assessing hand movements and hand activities within the Motor Assessment Scale (MAS, an existing instrument used for clinical assessment of motor performance in stroke survivors; (2 To examine the psychometric properties of these new measurement scales. Design. Scale development, followed by a multicenter observational study. Setting. Inpatient and outpatient occupational therapy programs in eight hospital and rehabilitation facilities in the United States and Canada. Participants. Patients (N=332 receiving stroke rehabilitation following left (52% or right (48% cerebrovascular accident; mean age 64.2 years (sd 15; median 1 month since stroke onset. Intervention. Not applicable. Main Outcome Measures. Data were tested for unidimensionality and reliability, and behavioral criteria were ordered according to difficulty level with Rasch analysis. Results. The new scales assessing hand movements and hand activities met Rasch expectations of unidimensionality and reliability. Conclusion. Following a multistep process of test development, analysis, and refinement, we have redesigned the two scales that comprise the hand function items on the MAS. The hand movement scale contains an empirically validated 10-behavior hierarchy and the hand activities item contains an empirically validated 8-behavior hierarchy.

    Turner syndrome (TS) is the complex phenotype of human females with complete or partial absence of the second sex chromosome, or monosomy X. A characteristic neurocognitive and psychosocial profile has also been described in TS females. Typically, specific deficits in visual-spatial/perceptual abilities, nonverbal memory function, motor function, executive function, and attentional abilities occur in TS children and adults of varying races and socioeconomic status. TS-associated psychosocial difficulties occur in the areas of maturity and social skills. We hypothesize that a subset of the neurocognitive deficits (visual-spatial/perceptual abilities) are genetically determined and result from abnormal expression of one or more X chromosome genes. In addition, a different subset of these neurocognitive deficits (memory, reaction time, and speeded motor function) result from estrogen deficiency and are at least somewhat reversible with estrogen treatment. The TS-associated psychosocial problems are most likely linked to these core neurocognitive deficits and do not reflect a separate and independent component of the syndrome. Turner syndrome research has progressed significantly over the last decade. The field has moved from descriptive reports based on single individuals or small clinical samples to the use of experimental designs with larger, more diverse and representative samples. This degree of variability among individuals with Turner syndrome in all domains (karyotype or genetic constitution, physical attributes, neurocognitive and social functioning) suggests the need to identify risk and protective factors contributing to the heterogeneity in the phenotype. Active education about TS and participation in patient advocacy groups such as the Turner Syndrome Society of the United States (http://www. turner-syndrome-us.org/) has provided new information for TS adults and families as well as a supportive peer group.

    Academic achievement of school age children can be affected by several factors such as nutritional status, demographics, and socioeconomic factors. Though evidence about the magnitude of malnutrition is well established in Ethiopia, there is a paucity of evidence about the association of nutritional status with academic performance among the nation's school age children. Hence, this study aimed to determine how nutritional status and cognitive function are associated with academic performance of school children in Goba town, South East Ethiopia. An institution based cross-sectional study was conducted among 131 school age students from primary schools in Goba town enrolled during the 2013/2014 academic year. The nutritional status of students was assessed by anthropometric measurement, while the cognitive assessment was measured by the Kaufman Assessment Battery for Children (KABC-II) and Ravens colored progressive matrices (Raven's CPM) tests. The academic performance of the school children was measured by collecting the preceding semester academic result from the school record. Descriptive statistics, bivariate and multivariable linear regression were used in the statistical analysis. This study found a statistically significant positive association between all cognitive test scores and average academic performance except for number recall (p = 0.12) and hand movements (p = 0.08). The correlation between all cognitive test scores and mathematics score was found positive and statistically significant (p academic subjects among school age children (ß = 0.53; 95 % CI: 0.11-0.95). A single unit change of age resulted 3.23 unit change in average score of all academic subjects among school age children (ß = 3.23; 95 % CI: 1.20-5.27). Nutritional status (height for age Z score) and wealth could be modifiable factors to improve academic performance of school age children. Moreover, interventions to improve nutrition for mothers and children may be

    Using a representative sample from the Dutch population, some psychosocial aspects of halitosis were examined. The results of the survey showed that almost 90% of the Dutch population aged 16 years and older were regularly faced with halitosis. Forty percent reported to be exposed to someone with halitosis at least once a week, men significantly more frequently than women. Although less strongly than body odour, halitosis was reported as being one of the most severe 'let-downs' in social interactions. The greater the social distance between subjects, the less likely is the chance that a person's attention will be drawn to halitosis experienced. When it comes to an unknown person, the chance was no more than 7%, suggesting that it is problematic to draw a person's attention to the presence of halitosis. Considering the potential social consequences of halitosis is it important that dentists and dental hygienists draw patients' attention to the presence of halitosis, when this is the case, thereby encouraging them to seek adequate treatment.

    We examined the long-term psychosocial trajectory in a consecutive and homogeneous series of 120 patients followed up for five years after corticoamygdalohippocampectomy (CAH). Evaluation of psychosocial variables at baseline and at five-year follow-up were compared. After five years of CAH, a significant improvement in educational level (p=0.004) and employment status (p0.05). A more favorable surgical outcome (Engel IA) was related to better psychiatric status (p=0.012). Poor psychosocial adjustment before surgery was the most important predictor of QOL outcome (p<0.05). Patients' trajectory after surgical treatment showed positive effects mainly in those with better seizure outcome. Our results emphasized the influence regarding baseline psychosocial functioning on postoperative psychosocial adjustment. Furthermore, many psychosocial gains and difficulties after surgery may be similar in developing and developed countries. Copyright © 2015 Elsevier Inc. All rights reserved.

  20. Pharmacological Augmentation of Psychosocial and Remediation Training Efforts in Schizophrenia

    Full Text Available Pharmacological approaches to cognitive enhancement have received considerable attention but have not had considerable success in improving their cognitive and functional targets. Other intervention strategies, such as cognitive remediation therapy (CRT, have been shown to enhance cognitive performance but have not been found to improve functional outcomes without additional psychosocial interventions. Recently, several studies have attempted to enhance the effects of CRT by adding pharmacological interventions to the CRT treatments. In addition, as CRT has been shown to synergistically improve the effects of psychosocial interventions, the combination of pharmacological therapies aimed at cognition and psychosocial interventions may itself provide a promising strategy for improving functional outcomes. This review and commentary examines the current state of interventions combining CRT and psychosocial treatments with pharmacological augmentation. Our focus is on the specific level of effect of the pharmacological intervention, which could be enhancing motivation, training efficiency, or the consolidation of therapeutic gains. Different pharmacological strategies (e.g., stimulants, plasticity-inducing agents, or attentional or alertness enhancers may have the potential to lead to different types of gains when combined with CRT or psychosocial interventions. The relative potential of these different mechanisms for immediate and durable effects is considered.

    Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) have been suggested to play a protective role during acute psychosocial stress, because they act as antagonists to the effects of the stress hormone cortisol. This study aims to investigate whether prolonged psychosocial stress, measured as perceived stress at work during the past week, is related to the capacity to produce DHEA and DHEA-S during acute psychosocial stress. It also aims to investigate whether prolonged perceived stress affects the balance between production of cortisol and DHEA-S during acute psychosocial stress. Thirty-six healthy subjects (19 men and 17 women, mean age 37 years, SD 5 years), were included. Perceived stress at work during the past week was measured by using the Stress-Energy (SE) Questionnaire. The participants were divided into three groups based on their mean scores; Low stress, Medium stress and High stress. The participants underwent the Trier Social Stress Test (TSST) and blood samples were collected before, directly after the stress test, and after 30 min of recovery. General Linear Models were used to investigate if the Medium stress group and the High stress group differ regarding stress response compared to the Low stress group. Higher perceived stress at work was associated with attenuated DHEA-S response during acute psychosocial stress. Furthermore, the ratio between the cortisol production and the DHEA-S production during the acute stress test were higher in individuals reporting higher perceived stress at work compared to individuals reporting low perceived stress at work. There was no statistical difference in DHEA response between the groups. This study shows that prolonged stress, measured as perceived stress at work during the past week, seems to negatively affect the capacity to produce DHEA-S during acute stress. Given the protective functions of DHEA-S, attenuated DHEA-S production during acute stress may lead to higher risk for adverse

    This article reports on the psychosocial development and factors influencing outcomes of 5-year-old children with cochlear implants (CIs) or hearing aids (HAs). It further examines differences between children with CIs and HAs with similar levels of hearing loss. Data were collected as part of the Longitudinal Outcomes of Children with Hearing Impairment study—a prospective, population-based study. Parents/caregivers of children completed the Strengths and Difficulties Questionnaire (n = 333), the Social Skills subscale from the Child Development Inventory (n = 317), and questionnaires on functional auditory behavior (Parents’ Evaluation of Aural/oral performance of Children), and demographics. Children completed assessments of nonverbal cognitive ability (Wechsler Non-verbal Scale of Ability) and language (Preschool Language Scale - fourth edition). On average, parent-rated Strengths and Difficulties Questionnaire scores on emotional or behavioral difficulties were within 1 SD of the normative mean; however, Child Development Inventory scores on social skills were more than 1 SD below the norm. Children with severe-to-profound hearing losses using HAs had significantly more behavioral problems than children with CIs. Regression analyses showed that non-verbal cognitive ability, language, and functional auditory behavior were significantly associated with psychosocial outcomes for children with HAs, whereas outcomes for children with CIs were associated with functional auditory behavior and the presence of additional disabilities. Age at hearing intervention, severity of hearing loss, and communication mode were not associated with outcomes. The results suggest that even children who develop good language ability with the help of a HA or CI may have psychosocial problems if they exhibit difficulties with listening and communicating in everyday environments. The findings have implications for developing interventions for young children with hearing

    Skin picking disorder (SPD) and trichotillomania (TTM) are common and oftentimes disabling disorders. 125 Participants with SPD and 152 with TTM undertook clinical and neurocognitive evaluation, and were grouped according to mild, moderate, or severe levels of psychosocial dysfunction. Relationships between functional impairment and other variables were explored using linear regression and categorical analyses. Greater functional impairment was associated with worse disease severity in both groups, and by later symptom onset and lower quality of life in TTM subjects. These results indicate that levels of self-reported psychosocial dysfunction have a strong association with specific clinical aspects of SPD and TTM.

    Full Text Available Essential Arterial Hypertension (EAHT is one of the most spread cardiovascular diseases. EAHT is considered to be a mostly psychosomatic disease, which can affect the psycho-social functioning (depression, anxiety as well as the neuro-cognitive one (attention, memory and executive function disorders. These could lead to the negative influence of the patient and important family members’ level of quality of life. The psycho-social factors (type A behaviour pattern, negative close relationships, social preasure etc. can also influence adherence to treatment and the control of arterial hypertension.

    To evaluate the benefits of the national stroke postacute care (PAC) program on clinical outcomes and subsequent healthcare utilization. Propensity score-matched case-control study using the National Health Insurance data. A total of 1480 stroke cases receiving PAC services and 3159 matched controls with similar stroke severity but without PAC services. Demographic characteristics, functional outcomes (modified Rankin Scale, Barthel Index, Lawton-Brody Instrumental Activities of Daily Living, Functional Oral Intake Scale, Mini-Nutritional Assessment, Berg Balance Test, Usual Gait Speed Test, 6-Minute Walk Test, Fugl-Meyer Assessment (modified sensation and motor), Mini-Mental State Examination, Motor Activity Log, and the Concise Chinese Aphasia Test), subsequent healthcare utilization (90-day stroke re-admission and emergency department visits), and 90-day mortality. After propensity score matching, baseline characteristics, stroke severity, and status of healthcare utilization before index stroke admission were similar between cases and controls. After PAC services, the case group obtained significant improvement in all functional domains and may have reduced subsequent disability. Among all functional assessments, balance was the most significantly improved domain and was suggestive for the reduction of subsequent falls risk and related injuries. Compared with controls, patients receiving PAC services had significantly lower 90-day hospital re-admissions [11.1% vs 21.0%, adjusted odds ratio (aOR) 0.47 with 95% confidence interval (CI) 0.34-0.64], stroke-related re-admissions (2.1% vs 8.8%, aOR 0.22, 95% CI 0.12-0.41), and emergency department visits (13.5% vs 24.0%, aOR 0.49, 95% CI 0.37-0.65), but the 90-day mortality rate remained similar between groups (1.4% case group vs 2.0% control group, aOR 0.68, 95% CI 0.29-1.62). PAC significantly improved the recovery of stroke patients in all functional domains through the program, with universal interorganizational

    Full Text Available Abstract Background This study aimed to systematically review the evidence from randomized controlled trials (RCTs and to conduct a meta-analysis of the effects of yoga on physical and psychosocial outcomes in cancer patients and survivors. Methods A systematic literature search in ten databases was conducted in November 2011. Studies were included if they had an RCT design, focused on cancer patients or survivors, included physical postures in the yoga program, compared yoga with a non-exercise or waitlist control group, and evaluated physical and/or psychosocial outcomes. Two researchers independently rated the quality of the included RCTs, and high quality was defined as >50% of the total possible score. Effect sizes (Cohen’s d were calculated for outcomes studied in more than three studies among patients with breast cancer using means and standard deviations of post-test scores of the intervention and control groups. Results Sixteen publications of 13 RCTs met the inclusion criteria, of which one included patients with lymphomas and the others focused on patients with breast cancer. The median quality score was 67% (range: 22–89%. The included studies evaluated 23 physical and 20 psychosocial outcomes. Of the outcomes studied in more than three studies among patients with breast cancer, we found large reductions in distress, anxiety, and depression (d = −0.69 to −0.75, moderate reductions in fatigue (d = −0.51, moderate increases in general quality of life, emotional function and social function (d = 0.33 to 0.49, and a small increase in functional well-being (d = 0.31. Effects on physical function and sleep were small and not significant. Conclusion Yoga appeared to be a feasible intervention and beneficial effects on several physical and psychosocial symptoms were reported. In patients with breast cancer, effect size on functional well-being was small, and they were moderate to large for psychosocial outcomes.

    Studies suggest early-onset depression (EOD) is associated with a more severe course of the depressive disorder, while late-onset depression (LOD) is associated with more cognitive and neuroimaging changes. This study examined if older adults with EOD, compared with those with LOD, would exhibit more severe symptoms of depression and, consistent with the glucocorticoid cascade hypothesis, have more hippocampal volume loss. A second goal was to determine if LOD, compared with EOD, would demonstrate more cognitive and neuroimaging changes. At regular intervals over a four-year period non-demented, older, depressed adults were assessed on the Mini-Mental Status Examination and the Montgomery-Asberg Depression Rating Scale. They were also assessed on magnetic resonance imaging. Compared with LOD, EOD had more depressive symptoms, more suicidal thoughts, and less social support. Growth curve analyses indicated that EOD demonstrated higher levels of residual depressive symptoms over time. The LOD group exhibited a greater decrement in cognitive scores. Contrary to the glucocorticoid cascade hypothesis, participants with EOD lost right hippocampal volume at a slower rate than did participants with LOD. Right cerebrum gray matter was initially smaller among participants with LOD. EOD is associated with greater severity of depressive illness. LOD is associated with more severe cognitive and neurological changes. These differences are relevant to understanding cognitive impairment in geriatric depression.

    Full Text Available Abstract Background Adverse psychosocial work environments may lead to impaired mental health, but it is still a matter of conjecture if demonstrated associations are causal or biased. We aimed at verifying whether poor psychosocial working climate is related to increase of redeemed subscription of antidepressant medication. Methods Information on all antidepressant drugs (AD purchased at pharmacies from 1995 through 2006 was obtained for a cohort of 21,129 Danish public service workers that participated in work climate surveys carried out during the period 2002–2005. Individual self-reports of psychosocial factors at work including satisfaction with the work climate and dimensions of the job strain model were obtained by self-administered questionnaires (response rate 77,2%. Each employee was assigned the average score value for all employees at his/her managerial work unit [1094 units with an average of 18 employees (range 3–120]. The risk of first-time AD prescription during follow-up was examined according to level of satisfaction and psychosocial strain by Cox regression with adjustment for gender, age, marital status, occupational status and calendar year of the survey. Results The proportion of employees that received at least one prescription of ADs from 1995 through 2006 was 11.9% and prescriptions rose steadily from 1.50% in 1996 to the highest level 6.47% in 2006. ADs were prescribed more frequent among women, middle aged, employees with low occupational status and those living alone. None of the measured psychosocial work environment factors were consistently related to prescription of antidepressant drugs during the follow-up period. Conclusion The study does not indicate that a poor psychosocial work environment among public service employees is related to prescription of antidepressant pharmaceuticals. These findings need cautious interpretation because of lacking individual exposure assessments.

    The Millon Clinical Multiaxial Inventory (MCMI) was administered to 144 men and 86 women within 1 month of admission to methadone maintenance treatment and was readministered 18 months following admission. Based on prior research, we hypothesized there would be significant decreases on scales measuring affective disturbance, anxiety, and social isolation and little change in scales measuring antisocial and narcissistic traits. In addition, it was hypothesized that changes on the MCMI would be related to retention in treatment and illicit drug use during the interim between initial assessment and follow-up. Data were analyzed using a multivariate analysis of variance (MANOVA) for repeated measures. There was an overall decrease in MCMI scores, indicating less psychopathology between initial assessment and follow-up. MCMI scales did not change as a function of retention status,
