    The objective of this study was to evaluate short-term efficacy and safety of aripiprazole in the treatment of irritability in children and adolescents with autistic disorder who were manifesting behaviors such as tantrums, aggression, self-injurious behavior, or a combination of these. This 8-week, double-blind, randomized, placebo-controlled, parallel-group study was conducted of children and adolescents (aged 6-17 years) with autistic disorder. Patients were randomly assigned (1:1) to flexibly dosed aripiprazole (target dosage: 5, 10, or 15 mg/day) or placebo. Efficacy outcome measures included the Aberrant Behavior Checklist irritability subscale and the Clinical Global Impression-Improvement score (CGI-I). Safety and tolerability were also assessed. Ninety-eight patients were randomly assigned to receive placebo (n = 51) or aripiprazole (n = 47). Mean improvement in Aberrant Behavior Checklist irritability subscale score was significantly greater with aripiprazole than with placebo from week 1 through week 8. Aripiprazole demonstrated significantly greater global improvements than placebo, as assessed by the mean CGI-I score from week 1 through week 8; however, clinically significant residual symptoms may still persist for some patients. Discontinuation rates as a result of adverse events (AEs) were 10.6% for aripiprazole and 5.9% for placebo. Extrapyramidal symptom-related AE rates were 14.9% for aripiprazole and 8.0% for placebo. No serious AEs were reported. Mean weight gain was 2.0 kg on aripiprazole and 0.8 kg on placebo at week 8. Aripiprazole was efficacious in children and adolescents with irritability associated with autistic disorder and was generally safe and well tolerated.

    Behavior problems are a common challenge for individuals with fragile X syndrome (FXS) and constitute the primary clinical outcome domain in trials testing new FXS medications. However, little is known about the relationship between caregiver-reported behavior problems and co-occurring conditions such as anxiety and attention problems. In this study, 350 caregivers, each with at least one son or daughter with full-mutation FXS, rated one of their children with FXS using the Aberrant Behavior Checklist-Community Version (ABC-C); the Anxiety subscale of the Anxiety, Depression, and Mood Scale; and the Attention/Hyperactivity Items from the Symptom Inventories. In addition to examining family consequences of these behaviors, this study also sought to replicate psychometric findings for the ABC-C in FXS, to provide greater confidence for its use in clinical trials with this population. Psychometric properties and baseline ratings of problem behavior were consistent with other recent studies, further establishing the profile of problem behavior in FXS. Cross-sectional analyses suggest that selected dimensions of problem behavior, anxiety, and hyperactivity are age related; thus, age should serve as an important control in any studies of problem behavior in FXS. Measures of anxiety, attention, and hyperactivity were highly associated with behavior problems, suggesting that these factors at least coincide with problem behavior. However, these problems generally did not add substantially to variance in caregiver burden predicted by elevated behavior problems. The results provide further evidence of the incidence of problem behaviors and co-occurring conditions in FXS and the impact of these behaviors on the family. © 2013 Wiley Periodicals, Inc.

    The purpose of this study was to characterize children with Down syndrome and attention-deficit hyperactivity disorder (ADHD) with disruptive behaviors using the Aberrant Behavior Checklist (ABC), and to measure the treatment effects of guanfacine on maladaptive behaviors. Subjects were enrolled from a group of outpatients who visited our clinic between 2002 and 2007. Subjects (N = 23) were children with Down syndrome ages 4 to 12 years (mean 7.4 ± 4.1), who met criteria for ADHD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition The Aberrant Behavior Checklist Irritability and Hyperactivity subscales each showed a significant decrease (P < .0001) at follow-up. The mean decline on Hyperactivity was 25% (-7.8 points), and for Irritability, 25% (-3.5 points). The mean composite score also declined by 24% (-12 points). Effect size differences on Irritability were moderate, whereas differences on Hyperactivity and composite score appeared large. Clinically important target behaviors were reduced. Medication was generally well tolerated and the incidence of treatment emergent side effects remained low. © The Author(s) 2016.

    To evaluate the short-term efficacy and safety of aripiprazole in the treatment of irritability in children and adolescents with autistic disorder. Two hundred eighteen children and adolescents (aged 6-17 years) with a diagnosis of autistic disorder, and with behaviors such as tantrums, aggression, self-injurious behavior, or a combination of these symptoms, were randomized 1:1:1:1 to aripiprazole (5, 10, or 15 mg/day) or placebo in this 8-week double-blind, randomized, placebo-controlled, parallel-group study. Efficacy was evaluated using the caregiver-rated Aberrant Behavior Checklist Irritability subscale (primary efficacy measure) and the clinician-rated Clinical Global Impressions-Improvement score. Safety and tolerability were also assessed. At week 8, all aripiprazole doses produced significantly greater improvement than placebo in mean Aberrant Behavior Checklist Irritability subscale scores (5 mg/day, -12.4; 10 mg/day, -13.2; 15 mg/day, -14.4; versus placebo, -8.4; all p < .05). All aripiprazole doses demonstrated significantly greater improvements in mean Clinical Global Impressions-Improvement score than placebo at week 8. Discontinuation rates due to adverse events were as follows: placebo 7.7%, aripiprazole 5 mg/day 9.4%, 10 mg/day 13.6%, and 15 mg/day 7.4%. The most common adverse event leading to discontinuation was sedation. There were two serious adverse events: presyncope (5 mg/day) and aggression (10 mg/day). At week 8, mean weight change (last observation carried forward) was as follows: placebo +0.3 kg, aripiprazole 5 mg/day +1.3 kg, 10 mg/day +1.3 kg, and 15 mg/day +1.5 kg; all p < .05 versus placebo. Aripiprazole was efficacious and generally safe and well tolerated in the treatment of children and adolescents with irritability associated with autistic disorder.

    2015-01-01

    Chronic, severe irritability is common in childhood and is very impairing. Furthermore, childhood irritability predicts suicidality, social impairment, and depressive and anxiety disorders in adulthood. Focusing on both normative and pathologic development, we review the construct of irritability from its origins in aggression and disruptive behavior research to its contemporary relevance for affective psychopathology. We then describe two broad neurocognitive systems that show promise in differentiating irritable from nonirritable youths: aberrant processing of emotional stimuli and impaired context-sensitive regulation. We suggest behavioral, neurocognitive, and physiologic measures that may aid in studying severe irritability and assessing its therapeutics. Finally, we argue for therapeutic trials targeting severe irritability that address emotional aspects of irritability in addition to the associated disruptive behavior. PMID:24342851

    Reliable and valid assessment of aberrant behaviors is essential in empirically verifying prevention and intervention for individuals with intellectual or developmental disabilities (IDD). Few instruments exist which assess behavior problems in infants. The current longitudinal study examined the performance of three behavior-rating scales for individuals with IDD that have been proven psychometrically sound in older populations: the Aberrant Behavior Checklist (ABC), the Behavior Problems Inventory (BPI-01), and the Repetitive Behavior Scale - Revised (RBS-R). Data were analyzed for 180 between six and 36 months old children at risk for IDD. Internal consistency (Cronbach's α) across the subscales of the three instruments was variable. Test-retest reliability of the three BPI-01 subscales ranged from .68 to .77 for frequency ratings and from .65 to .80 for severity ratings (intraclass correlation coefficients). Using a multitrait-multimethod matrix approach high levels of convergent and discriminant validity across the three instruments was found. As anticipated, there was considerable overlap in the information produced by the three instruments; however, each behavior-rating instrument also contributed unique information. Our findings support using all three scales in conjunction if possible. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The Aberrant Behavior Checklist (ABC) is a 58-item rating scale that was developed primarily to measure the effects of pharmacological intervention in individuals living in residential facilities. This study investigated the use of the ABC in a sample of community children with mental retardation. Teacher ratings on the ABC were collected on 666 students attending special classes. The data were factor analyzed and compared with other studies using the ABC. In addition, subscales were analyzed as a function of age, sex, and classroom placement, and preliminary norms were derived. A four-factor solution of the ABC was obtained. Congruence between the four derived factors and corresponding factors from the original ABC was high (congruence coefficients ranged between .87 and .96). Classroom placement and age had significant effects on subscale scores, whereas sex failed to affect ratings. The current results are sufficiently close to the original factor solution that the original scoring method can be used with community samples, although further studies are needed to look at this in more detail.

    Nicotinic acetylcholine receptors (nAChRs), particularly the α7 nAChR, are implicated in the pathophysiology of both autism spectrum disorder (ASD) and aggressive behavior. We explored the feasibility, tolerability, and preliminary efficacy of targeting nAChRs using transdermal nicotine to reduce aggressive symptoms in adults with ASD. Eight subjects were randomized in a double-blind crossover trial of 7 mg transdermal nicotine or placebo, each for 1 week. All participants tolerated nicotine treatment well. Five subjects contributed data to the primary outcome, Aberrant Behavior Checklist-Irritability (ABC-I) subscale change from baseline, which was improved by nicotine compared to placebo. Sleep ratings were also improved by nicotine and correlated with ABC-I improvement. These findings support further investigation of nAChR agonists for aggression and sleep in ASD.

    The aim of this study was to evaluate the short-term efficacy and safety of lurasidone in treating irritability associated with autistic disorder. In this multicenter trial, outpatients age 6-17 years who met DSM-IV-TR criteria for autistic disorder, and who demonstrated irritability, agitation, and/or self-injurious behaviors were randomized to 6 weeks of double-blind treatment with lurasidone 20 mg/day (N = 50), 60 mg/day (N = 49), or placebo (N = 51). Efficacy measures included the Aberrant Behavior Checklist Irritability subscale (ABC-I, the primary endpoint) and the Clinical Global Impressions, Improvement (CGI-I) scale, and were analyzed using a likelihood-based mixed model for repeated measures. Least squares (LS) mean (standard error [SE]) improvement from baseline to Week 6 in the ABC-I was not significantly different for lurasidone 20 mg/day (-8.8 [1.5]) and lurasidone 60 mg/day (-9.4 [1.4]) versus placebo (-7.5 [1.5]; p = 0.55 and 0.36, respectively). CGI-I scores showed significantly greater LS mean [SE] improvement at Week 6 for lurasidone 20 mg/day versus placebo (2.8 [0.2] vs. 3.4 [0.2]; p = 0.035) but not for lurasidone 60 mg/day (3.1 [0.2]; p = 0.27). Discontinuation rates due to adverse events were: lurasidone 20 mg/day, 4.1%; 60 mg/day, 3.9%; and placebo, 8.2%. Adverse events with an incidence ≥10% (lurasidone combined, placebo) included vomiting (18.0, 4.1%) and somnolence (12.0, 4.1%). Modest changes were observed in weight and selected metabolic parameters. In this study, once-daily, fixed doses of 20 and 60 mg/day of lurasidone were not demonstrated to be efficacious compared to placebo for the short-term treatment of children and adolescents with moderate-to-severe irritability associated with autistic disorder.

    We investigated the effectiveness and tolerability of aripiprazole in the treatment of irritability in Asian children and adolescents (6-17 years) with autistic disorder in a 12-week, multinational, multicenter, open-label study. Sixty-seven subjects (10.0 ± 3.1 years old, 52 boys) were enrolled and treated with flexibly dosed aripiprazole for 12 weeks (mean dose, 5.1 ± 2.5 mg; range 2-15 mg). Aripiprazole significantly reduced the mean caregiver-rated scores for the Irritability, Lethargy/Social Withdrawal, Stereotypy, Hyperactivity, and Inappropriate Speech subscales of the Aberrant Behavior Checklist from baseline to week 12 (p < 0.001 for all subscales). Clinician-rated Clinical Global Impression Severity of Illness scale score also improved from baseline through week 12 (p < 0.001). The most common adverse event was weight gain and no serious adverse event related to aripiprazole treatment was noted. Our results suggest that aripiprazole is effective and generally tolerable in the treatment of irritability in Asian children and adolescents with autistic disorder. Further studies with larger sample sizes and longer treatment durations are required.

    The Aberrant Behavior Checklist—Community (ABC-C; Aman, Burrow, & Wolford, 1995) has been increasingly adopted as a primary tool for measuring behavioral change in clinical trials for individuals with fragile X syndrome (FXS). To our knowledge, however, no study has documented the longitudinal trajectory of aberrant behaviors in individuals with FXS using the ABC-C. As part of a larger longitudinal study, we examined scores obtained on the ABC-C subscales for 124 children and adolescents (64 males, 60 females) with FXS who had two or more assessments (average interval between assessments was approximately 4 years). Concomitant changes in age-equivalent scores on the Vineland Adaptive Behavior Scales (VABS) were also examined. As expected for an X-linked genetic disorder, males with FXS obtained significantly higher scores on all subscales of the ABC-C and significantly lower age-equivalent scores on the VABS than females with FXS. In both males and females with FXS, scores on the Irritability/Agitation and Hyperactivity/Noncompliance subscales of the ABC-C decreased significantly with age, with little to no change occurring over time on the Lethargy/Social Withdrawal, Stereotypic Behavior, and Inappropriate Speech subscales. The decrease in scores on the Hyperactivity/Noncompliance domain was significantly greater for males than for females. In both males and females, age-equivalent scores on the VABS increased significantly over this developmental period. These results establish a basis upon which to evaluate long-term outcomes from intervention-based research. However, longitudinal direct observational studies are needed to establish whether the severity of problem behavior actually decreases over time in this population. PMID:25129200

    Individuals with autistic disorder (autism) frequently exhibit significant irritability marked by severe tantrums, aggression, and self-injury. Despite advances in the treatment of this symptom domain in autism, there remains an ongoing need for more effective and better tolerated pharmacotherapies. The aim of this study is to determine the effectiveness and tolerability of paliperidone for irritability in autism. This is a prospective, 8-week open-label study of paliperidone in 25 adolescents and young adults with autism. Primary outcome measures included the Clinical Global Impressions-Improvement (CGI-I) Scale and the Irritability subscale of the Aberrant Behavior Checklist (ABC-I). Concomitant medications (except antipsychotics) were permitted if dosages were stable for ≥2 months. Twenty-one (84 %) of 25 subjects ages 12-21 years (mean 15.3 years) responded to paliperidone, based on a CGI-I Scale score of 1 or 2 (very much or much improved) and ≥25 % improvement on the ABC-I. The mean final dosage of paliperidone was 7.1 mg/day (range 3-12 mg/day). Two subjects discontinued paliperidone prior to study completion (moderate sedation, n = 1; nonresponse, n = 1). Mild-to-moderate extrapyramidal symptoms were recorded in four subjects. A mean weight gain of 2.2 ± 2.6 kg (range -3.6 to +7.9 kg) was recorded. Mean age- and sex-normed body mass index increased from 23.6 to 24.2 (p ≤ 0.001). Mean serum prolactin increased from 5.3 to 41.4 ng/mL (p ≤ 0.0001). Paliperidone treatment was associated with significant improvement in irritability and was generally well tolerated. Larger scale, placebo-controlled studies are needed to elucidate the efficacy and tolerability of paliperidone in this population.

    Anger, irritability, and aggression are among the most common reasons for child mental health referrals. This review is focused on two forms of behavioral interventions for these behavioral problems: Parent management training (PMT) and cognitive-behavioral therapy (CBT). First, we provide an overview of anger/irritability and aggression as the treatment targets of behavioral interventions, followed by a discussion of the general principles and techniques of these treatment modalities. Then we discuss our current work concerning the transdiagnostic approach to CBT for anger, irritability, and aggression. PMT is aimed at improving aversive patterns of family interactions that engender children's disruptive behavior. CBT targets deficits in emotion regulation and social problem-solving that are associated with aggressive behavior. Both forms of treatment have received extensive support in randomized controlled trials. Given that anger/irritability and aggressive behavior are common in children with a variety of psychiatric diagnoses, a transdiagnostic approach to CBT for anger and aggression is described in detail. PMT and CBT have been well studied in randomized controlled trials in children with disruptive behavior disorders, and studies of transdiagnostic approaches to CBT for anger and aggression are currently underway. More work is needed to develop treatments for other types of aggressive behavior (e.g., relational aggression) that have been relatively neglected in clinical research. The role of callous-unemotional traits in response to behavioral interventions and treatment of irritability in children with anxiety and mood disorders also warrants further investigation.

    We examined the relationship between sleep duration and awakenings to Aberrant Behavior Checklist-Community (ABC-C) and Autism Diagnostic Observation Schedule (ADOS-2) scores in hospitalized youth with ASD and behavioral disturbance. Participants included 106 patients with a stay of at least 10 nights. Sleep in the hospital was recorded by staff observation. Higher scores on the ABC-C (irritability, stereotypy, and hyperactivity subscales) at admission were significantly associated with fewer minutes slept during the last five nights of hospitalization. There was no association between total awakenings and ABC-C scores or ADOS-2 comparison scores. Improved understanding of the relationship between sleep quality and maladaptive behavior in this challenging cohort of patients with ASD is vital to the definition and design of future effective interventions.

Aripiprazole was found to be more effective in reducing irritability compared with placebo at 8 weeks, SMD −0.64 [−0.90 to −0.39, P < 0.00001] as determined by the Aberrant Behaviour Checklist irritability subscale (ABC-I). Pooled data from two eight week trials show that sedation is the most commonly reported adverse event. Statistically significant weight gain was also associated with aripiprazole, but there was a decrease in serum prolactin. Most adverse effects were deemed to be mild to moderate in severity. Four open trials and three case series all show support for aripiprazole in reducing the behavioural symptoms of autism. Long-term studies are required to determine the efficacy and safety of aripiprazole in autistic disorder in children. PMID:23861644

    Patients with autism spectrum disorders (ASDs) exhibit core autistic symptoms including social impairments from early childhood and mostly show secondary disabilities such as irritability and aggressive behavior based on core symptoms. However, there are still no radical treatments of social impairments in these patients. Oxytocin has been reported to play important roles in multiple social behaviors dependent on social recognition, and has been expected as one of the effective treatments of social impairments of patients with ASDs. We present a case of a 16-year-old girl with autistic disorder who treated by long-term administration of oxytocin nasal spray. Her autistic symptoms were successfully treated by two month administration; the girl's social interactions and social communication began to improve without adverse effects. Her irritability and aggressive behavior also improved dramatically with marked decreases in aberrant behavior checklist scores from 69 to 7. This case is the first to illustrate long-term administration of oxytocin nasal spray in the targeted treatment of social impairments in a female with autistic disorder. This case suggests that long-term nasal oxytocin spray is promising and well-tolerated for treatment of social impairments of patients with ASDs.

    In a series of experiments, we assessed the efficacy of using autistic children's aberrant behaviors as reinforcers to increase their correct task responding. In Experiment 1, reinforcer conditions of stereotypy, food, and varied (food or stereotypy) were compared. In Experiment 2, the conditions were delayed echolalia, food, and varied (food or delayed echolalia), and in Experiment 3, perseverative behavior was compared with stereotypy and food as potential reinforcers. A multielement design was used for all comparisons, and side-effect measures were recorded during and after teaching sessions as well as at home. Results indicated that, in general, task performance was highest when brief opportunities to engage in aberrant behaviors were provided as reinforcers. Edibles were associated with the lowest performance. Furthermore, no negative side effects (e.g., an increase in aberrant behaviors) occurred. The results are discussed in terms of suggesting a more pragmatic treatment approach by addressing the contingent use of autistic children's aberrant behaviors as reinforcers. PMID:2373653

    In this study realised in collaboration with the department of psychology and parapsychology of Andhra University, validation of the Aberrant Behavior Checklist-Community (ABC-C) in Telugu, the official language of Andhra Pradesh, one of India's 28 states, was carried out. To assess the factor validity and reliability of this Telugu version, 120 participants with moderate to profound intellectual disability (94 men and 26 women, mean age 25.2, SD 7.1) were rated by the staff of the Lebenshilfe Institution for Mentally Handicapped in Visakhapatnam, Andhra Pradesh, India. Rating data were analysed with a confirmatory factor analysis. The internal consistency was estimated by Cronbach's alpha. To confirm the test-retest reliability, 50 participants were rated twice with an interval of 4 weeks, and 50 were rated by pairs of raters to assess inter-rater reliability. Confirmatory factor analysis revealed that the root mean square error of approximation (RMSEA) was equal to 0.06, the comparative fit index (CFI) was equal to 0.77, and the Tucker Lewis index (TLI) was equal to 0.77, which indicated that the model with five correlated factors had a good fit. Coefficient alpha ranged from 0.85 to 0.92 across the five subscales. Spearman's rank correlation coefficients for inter-rater reliability tests ranged from 0.65 to 0.75, and the correlations for test-retest reliability ranged from 0.58 to 0.76. All reliability coefficients were statistically significant (P < 0.01). The factor validity and reliability of Telugu version of the ABC-C evidenced factor validity and reliability comparable to the original English version and appears to be useful for assessing behaviour disorders in Indian people with intellectual disabilities. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Community-based specialist behavior therapy teams may be helpful in managing challenging behavior, but evidence of their effectiveness is limited. This study was designed to examine the effectiveness and costs associated with treatment by a specialist behavior therapy team. This was a parallel-group, randomized, single-blind controlled trial carried out in an intellectual disabilities service in England. Participants were 63 male and female service users with mild to severe intellectual disability who presented with challenging behavior. The interventions were standard treatment plus applied behavioral analysis (N=32) and standard treatment only (N=31). The primary outcome measure was challenging behavior, as measured by total and subscale scores on the Aberrant Behavior Checklist 3 and 6 months after randomization. Secondary outcome measures were psychiatric comorbidity assessed at 3 and 6 months using the Psychiatric Assessment Schedule for Adults With a Developmental Disability Checklist (PAS-ADD) and total costs recorded at 6 months. Multilevel modeling was used to compare square root transformations of Aberrant Behavior Checklist scores. Significant differences were found in the transformed total scores on the Aberrant Behavior Checklist (difference=-0.89, 95% CI=-1.74 to -0.04) and transformed lethargy and hyperactivity subscale scores (common intervention effect=-0.56, 95% CI=-0.97 to -0.15). Standard care participants fared worse on the PAS-ADD comorbid organic disorder subscale. There was a clear trend for lower overall costs of the intervention. Use of a specialist behavior therapy team in addition to standard treatment appears to be more effective in improving challenging behavior and may have financial advantages over standard treatment.

    The purpose of this study was to evaluate the long-term safety and efficacy of aripiprazole in treating irritability in pediatric patients (6-17 years) with autistic disorder (AD) in Japan. In this open-label extension study, patients who had completed a previous randomized, double-blind, placebo-controlled 8-week study were enrolled and were flexibly dosed with aripiprazole (1-15 mg/day) until the new indication of irritability in pediatric autism spectrum disorder was approved in Japan. Seventy (81%) out of 86 enrolled patients completed week-48 assessments. The mean duration of treatment was 694.9 days. The mean daily dose of aripiprazole over the treatment period was 7.2 mg and the mean of the final dose was 8.5 mg. The most common treatment-emergent adverse events (TEAE; ≥20%) included nasopharyngitis, somnolence, influenza, and increased weight. The majority of these TEAE were mild or moderate in severity, and there were no deaths, and no clinically relevant findings in laboratory values except prolactin decrease, vital signs, height, or ECG parameters. At week 48 (observed case), the mean change from baseline in the Irritability subscale score for the Aberrant Behavior Checklist Japanese Version was -6.3 in prior placebo patients and -2.6 in prior aripiprazole patients. Aripiprazole was generally safe, well tolerated, and effective in the long-term treatment of irritability associated with AD in Japanese pediatric patients. © 2017 The Authors.

However, little is known about the developmental trajectory of irritability or how child irritability interacts with maternal depression. The present study (1) identifies classes of irritability trajectories from toddlerhood to middle childhood; (2) characterizes maternal depression and other family, social environment, and child variables within each irritability trajectory class; and (3) as a more exploratory analysis, examines bidirectional associations between maternal depression and child irritability. Method 4,898 families from the Fragile Families and Child Wellbeing Study reported on irritability symptoms at ages 3, 5, and 9, assessed with items from the Child Behavior Checklist. Parental major depressive episode was assessed using the Composite International Diagnostic Interview – Short Form at child ages 1, 3, 5, 9. Results A latent class growth analysis identified five irritability classes: low decreasing; moderate decreasing; high steady; initially very high, then decreasing; and high increasing. Children with more severe irritability trajectories are more likely to have mothers with recurrent depression, and, with the exception of the most severe (high increasing irritability) class, were more likely to have mothers who were exposed to violence. Moreover, paternal depression and alcohol use, as well as maternal drug and alcohol use, were also risk factors for membership in the more severe irritability classes. A latent auto-regressive cross-lag model showed that child irritability at ages 3 and 5 is associated with increased mother depression at 5 and 9, respectively. Conversely, mother depression at child ages 1 and 3 is associated with increased child irritability at 3 and 5.

    Autistic disorder is a neuropsychiatric syndrome characterized by deficits in social interaction; qualitative impairments in communication; and restricted, repetitive, and stereotyped patterns of behavior, interests, or activities. It is classified as a type of pervasive developmental disorder (PDD). All PDDs have a qualitative impairment in social relatedness. However, many individuals with PDDs have interfering symptoms, including irritability (aggression, self-injurious behavior, and severe tantrums). Behavioral therapy is often helpful in decreasing these behaviors; however, sometimes adjunctive medications are needed, because of the intensity and severity of irritability. Numerous medications have been tested on patients with PDDs. Although many of these medications have been demonstrated to be useful, no clear main treatment for PDD has emerged. Despite the efficacy of some of the medicines, acceptability and side effects have proven to be barriers to their use. Yokukansan (TJ-54), a traditional Japanese medicine, is composed of seven kinds of dried herbs. It is widely prescribed in clinical situations for treating psychiatric disorders by acting mainly on the glutamatergic and serotonergic nervous system. Recent studies indicate that TJ-54 may be safe and useful in treating behavioral and psychological symptoms in dementia patients. We aimed at evaluating both the efficacy and the safety of TJ-54 in patients with PDDs. This was a 12 week prospective, open-label investigation of TJ-54 in 20 children and adolescents ages 6-17 years diagnosed with PDDs. Primary outcome measures included the Clinical Global Impressions-Improvement of Illness Scale (CGI-I), Children's Global Assessment Score (CGAS), and the Aberrant Behavior Checklist (ABC) irritability subscale. Twenty subjects, ages 6-17 years, received TJ-54 in the dosage range of 2.5-7.5 g/day. The CGI-I was significantly improved from 8 weeks (p<0.001). The mean CGAS was 31.92 at baseline, whereas the mean

The purpose of the current study was to establish different classes of rational or appropriate verbal behavior in a woman with developmental disabilities and evaluate the effects on her psychotic or aberrant vocal verbal behavior. Similar to a previous study (Arntzen, Ro Tonnessen, & Brouwer, 2006), the results of the current study suggested that the procedure helped to establish a repertoire of appropriate functional vocal verbal behavior in the participant. Overall, the results suggested the effectiveness of an intervention based on training various classes of verbal behavior in decreasing aberrant verbal behavior. PMID:22754112

    The present study extends our previous work characterizing the behavioral features of autistic-spectrum disorder (ASD) in Down syndrome (DS) using the Aberrant Behavior Checklist (ABC) and Autism Behavior Checklist (AutBehav). We examined which specific behaviors distinguished the behavioral phenotype of DS + ASD from other aberrant behavior disorders in DS, by determining the relative contribution of ABC and AutBehav subscales and items to the diagnosis of ASD. A total of 127 subjects (aged 2-24 years; mean age: 8.4 years; approximately 70% male), comprising: a cohort of 64 children and adolescents with DS and co-morbid ASD (DS + ASD), 19 with DS and stereotypic movement disorder (DS + SMD), 18 with DS and disruptive behaviors (DS + DB), and 26 with DS and no co-morbid behavior disorders (DS + none) were examined using the aforementioned measures of aberrant behavior. We found that subjects with DS + ASD showed the most severe aberrant behavior, especially stereotypy compared to DS + none and lethargy/social withdrawal and relating problems compared to DS + SMD. Specifically, relatively simple stereotypic behavior differentiated DS + ASD from DS + DB, whereas odd/bizarre stereotypic and anxious behavior characterized DS + ASD relative to DS + SMD and DS + none. Additionally, in a subset of subjects with DS + ASD and anxiety, social withdrawal was particularly pronounced. Overall, our findings indicate that a diagnosis of DS + ASD represents a distinctive set of aberrant behaviors marked by characteristic odd/bizarre stereotypic behavior, anxiety, and social withdrawal.

    Disruptive behavior is common in children with autism spectrum disorder. Behavioral interventions are used to treat disruptive behavior but have not been evaluated in large-scale randomized trials. To evaluate the efficacy of parent training for children with autism spectrum disorder and disruptive behavior. This 24-week randomized trial compared parent training (n = 89) to parent education (n = 91) at 6 centers (Emory University, Indiana University, Ohio State University, University of Pittsburgh, University of Rochester, Yale University). We screened 267 children; 180 children (aged 3-7 years) with autism spectrum disorder and disruptive behaviors were randomly assigned (86% white, 88% male) between September 2010 and February 2014. Parent training (11 core, 2 optional sessions; 2 telephone boosters; 2 home visits) provided specific strategies to manage disruptive behavior. Parent education (12 core sessions, 1 home visit) provided information about autism but no behavior management strategies. Parents rated disruptive behavior and noncompliance on co-primary outcomes: the Aberrant Behavior Checklist-Irritability subscale (range, 0-45) and the Home Situations Questionnaire-Autism Spectrum Disorder (range, 0-9). On both measures, higher scores indicate greater severity and a 25% reduction indicates clinical improvement. A clinician blind to treatment assignment rated the Improvement scale of the Clinical Global Impression (range, 1-7), a secondary outcome, with a positive response less than 3. At week 24, the Aberrant Behavior Checklist-Irritability subscale declined 47.7% in parent training (from 23.7 to 12.4) compared with 31.8% for parent education (23.9 to 16.3) (treatment effect, -3.9; 95% CI, -6.2 to -1.7; P < .001, standardized effect size = 0.62). The Home Situations Questionnaire-Autism Spectrum Disorder declined 55% (from 4.0 to 1.8) compared with 34.2% in parent education (3.8 to 2.5) (treatment effect, -0.7; 95% CI, -1.1 to -0.3; P

    The aim of the present study was to standardize and generate psychometric evidence of the German language versions of two well-established English language mental health instruments: the Aberrant Behavior Checklist-Community (ABC-C) and the Psychiatric Assessment Schedule for Adults with Developmental Disabilities (PAS-ADD) Checklist. New methods in this field were introduced: a simulation method for testing the factor structure and an exploration of long-term stability over two years. The checklists were both administered to a representative sample of 270 individuals with intellectual disability (ID) and, two years later in a second data collection, to 128 participants of the original sample. Principal component analysis and parallel analysis were performed. Reliability measures, long-term stability, subscale intercorrelations, as well as standardized norms were generated. Prevalence of mental health problems was examined. Psychometric properties were mostly excellent, with long-term stability showing moderate to strong effects. The original factor structure of the ABC-C was replicated. PAS-ADD Checklist produced a similar, but still different structure compared with findings from the English language area. The overall prevalence rate of mental health problems in the sample was about 20%. Considering the good results on the measured psychometric properties, the two checklists are recommended for the early detection of mental health problems in persons with ID.

    2014-01-01

    Irritable bowel syndrome (IBS) is considered a biopsychosocial disorder, whose onset and precipitation are a consequence of interaction among multiple factors which include motility disturbances, abnormalities of gastrointestinal sensation, gut inflammation and infection, altered processing of afferent sensory information, psychological distress, and affective disturbances. Several models have been proposed in order to describe and explain IBS, each of them focusing on specific aspects or mechanisms of the disorder. This review attempts to present and discuss different determinants of IBS and its symptoms, from a cognitive behavioral therapy framework, distinguishing between the developmental predispositions and precipitants of the disorder, and its perpetuating cognitive, behavioral, affective and physiological factors. The main focus in understanding IBS will be placed on the numerous psychosocial factors, such as personality traits, early experiences, affective disturbances, altered attention and cognitions, avoidance behavior, stress, coping and social support. In conclusion, a symptom perpetuation model is proposed. PMID:24944466

    Progress in clinical research and in empirically supported interventions in the area of psychopathology in intellectual disabilities (ID) depends on high-quality assessment instruments. To this end, psychometric properties of four instruments were examined: the Aberrant Behavior Checklist (ABC), the Assessment of Dual Diagnosis (ADD), the Anxiety, Depression and Mood Scale (ADAMS), and the Social Performance Survey Schedule (SPSS). Data were collected in two community-based groups of adults with mild to profound ID (n = 263). Subscale reliability (internal consistency) ranged from fair to excellent for the ABC, the ADAMS, and the SPSS (mean coefficient α across ABC subscales was .87 (ranging from fair to excellent), the ADAMS subscales .83 (ranging from fair to good), and the SPSS subscales .91 (range from good to excellent). The ADD subscales had generally lower reliability scores with a mean of .59 (ranging from unacceptable to good). Convergent and discriminant validity was determined by bivariate Spearman ρ correlations between subscales of one instrument and the subscales of the other three instruments. For the most part, all four instruments showed solid convergent and discriminant validity. To examine the factorial validity, Confirmatory Factor Analyses (CFA) were attempted with the inter-item covariance matrix of each instrument. Generally, the data did not show good fits with the measurement models for the SPSS, ABC, or the ADAMS (CFA analyses with the ADD would not converge). However, most of the items on these three instruments had significant loadings on their respective factors. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Several studies have shown that personality traits and attitudes toward traffic safety predict aberrant driving behaviors and crash involvement. However, this process has not been adequately investigated in professional drivers, such as bus drivers. The present study used a personality-attitudes model to assess whether personality traits predicted aberrant self-reported driving behaviors (driving violations, lapses, and errors) both directly and indirectly, through the effects of attitudes towards traffic safety in a large sample of bus drivers. Additionally, the relationship between aberrant self-reported driving behaviors and crash risk was also assessed. Three hundred and one bus drivers (mean age=39.1, SD=10.7 years) completed a structured and anonymous questionnaire measuring personality traits, attitudes toward traffic safety, self-reported aberrant driving behaviors (i.e., errors, lapses, and traffic violations), and accident risk in the last 12 months. Structural equation modeling analysis revealed that personality traits were associated to aberrant driving behaviors both directly and indirectly. In particular altruism, excitement seeking, and normlessness directly predicted bus drivers' attitudes toward traffic safety which, in turn, were negatively associated with the three types of self-reported aberrant driving behaviors. Personality traits relevant to emotionality directly predicted bus drivers' aberrant driving behaviors, without any mediation of attitudes. Finally, only self-reported violations were related to bus drivers' accident risk. The present findings suggest that the hypothesized personality-attitudes model accounts for aberrant driving behaviors in bus drivers, and provide the empirical basis for evidence-based road safety interventions in the context of public transport.

    language and speech-language intervention. to evaluate the development process of autistic children, in a direct and indirect intervention context based on the responses of mothers to the Autism Behavior Checklist. the research sample consisted of 11 mothers of children diagnosed, according to the criteria established by the DSM IVtr (APA, 2002), with autism (six) and with Asperger Syndrome (five) and who were seen at the Investigation Laboratory of Global Developmental Disorders of the Federal University of São Paulo. These children were randomly divided into two groups: Six were receiving both direct and indirect intervention (TG), and five were receiving indirect intervention exclusively (OG). The Autism Behavior Checklist (Krug et al., 1993) was used, adapted to the Portuguese language by Marteleto (2003). This behavior checklist (57 items) allows the detailed description of non-adaptable characteristics regarding the following areas: sensory, use of the body and object, Language, Psycho-social and Relational. The questionnaire was filled in during an interview on three occasions: at the beginning of intervention, after six months and at the end of 12 months. after statistical analysis it was observed that there was a greater development in the total scores and in the areas of language, psycho-social and relational for the TG. This suggests a greater development pattern during the studied period for this group. the mothers of both groups observed behavioral changes. The better scores observed for the TG is probably related to the effectiveness of direct intervention, and not to the lack of attention of parents in the OG in recognizing behavioral changes in their children.

    To evaluate the efficacy and safety of aripiprazole versus placebo in preventing relapse of irritability symptoms associated with autistic disorder in pediatric patients. This multicenter, double-blind, randomized, placebo-controlled, relapse-prevention trial enrolled patients (6-17 years) who met the current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DMS-IV-TR) criteria for autistic disorder and who also had serious behavioral problems (ie, tantrums, aggression, self-injurious behavior, or a combination of these behavioral problems) between March 2011 and June 2012. In phase 1, single-blind aripiprazole was flexibly dosed (2-15 mg/d) for 13-26 weeks. Patients with a stable response (≥ 25% decrease in Aberrant Behavior Checklist-irritability subscale score and a rating of "much improved" or "very much improved" on the Clinical Global Impressions-Improvement scale) for 12 consecutive weeks were randomized into phase 2 to continue aripiprazole or switch to placebo. Treatment was continued until relapse or up to 16 weeks. The primary end point was time from randomization to relapse. Eighty-five patients were randomized in phase 2. The difference in time to relapse between aripiprazole and placebo was not statistically significant (P = .097). Kaplan-Meier relapse rates at week 16 were 35% for aripiprazole and 52% for placebo (hazard ratio [HR] = 0.57; number needed to treat [NNT] = 6). The most common adverse events during phase 1 were weight increase (25.2%), somnolence (14.8%), and vomiting (14.2%); and, during phase 2 (aripiprazole vs placebo), they were upper respiratory tract infection (10.3% vs 2.3%), constipation (5.1% vs 0%), and movement disorder (5.1% vs 0%). In this study, there was no statistically significant difference between aripiprazole and placebo in time to relapse during maintenance therapy. However, the HR and NNT suggest some patients will benefit from maintenance treatment. Patients receiving

    A hyperglutamatergic state has been shown to play a possible role in the pathophysiology of autistic disorders. Riluzole is a glutamate-modulating agent with neuroprotective properties, which has been shown to have positive effects in many neuropsychiatric disorders. The aim of this study was to assess the efficacy and tolerability of riluzole as an adjunctive to risperidone in the treatment of irritability in autistic children who were not optimally responding to previous medications. This was a 10-week, randomized, double-blind, parallel-group, placebo-controlled trial. The study enrolled male and female outpatients aged 5-12 years with a diagnosis of autistic disorder based on the DSM-IV-TR criteria and a score of ≥12 on the Aberrant Behavior Checklist-Community (ABC-C) irritability subscale who had discontinued other medications because of a lack of efficacy. Subjects received riluzole (titrated to 50 or 100 mg/day based on bodyweight) or placebo in addition to risperidone (titrated up to 2 or 3 mg/day based on bodyweight) for 10 weeks. Patients were assessed at baseline, week 5, and week 10. The primary outcome measure was the difference in the change in the ABC-C irritability subscale score from baseline to week 10 between the two groups. We also compared changes in other ABC-C subscale scores and Clinical Global Impressions-Improvement (CGI-I) scale scores between the two groups. Forty-nine patients were enrolled in the study, and forty children completed the trial (dropouts: placebo = 4, riluzole = 5). A significantly greater improvement in the study primary outcome (the ABC-C irritability subscale score) was achieved by the riluzole-treated children compared with the placebo group (P = 0.03). Patients in the riluzole group also showed significantly greater improvement on the lethargy/social withdrawal (P = 0.02), stereotypic behavior (P = 0.03), and hyperactivity/non-compliance subscales (P = 0.005), but not on the inappropriate speech

    Patients' irritability and aggression have been linked to caregiver depression, but the behaviors that most burden caregivers are not yet definitively identified. This study examines the connection between behavioral and psychological symptoms of dementia (BPSD) and the burnout of caregivers caring for home-dwelling elders with dementia symptoms in Japan. 80 Japanese rural and urban family caregivers completed detailed questionnaires about their experiences in caring for demented family members. We statistically analyzed the results for correlations between types of dementia, Pines Burnout, and Caregiver Distress. BPSD symptom severity significantly correlated with caregiver distress. The dementia symptoms most strongly correlated with caregiver burnout were: aggression, irritability, abnormal motor behavior, and hallucinations. Among the commonest symptoms, apathy, anxiety, and depression did not seriously aggravate caregiver burnout. Caregivers displayed higher burnout facing agitation/aggression, irritability, aberrant motor behavior, and hallucinations. Caregivers' reported distress was surprisingly dissimilar to their burnout scores; patients' delusions and anxiety led to higher distress reporting but not to burnout. Advance diagnosis of BPSD symptoms should be helpful to support nurses and caregivers of dementia patients. Particular support should be considered for caregivers and nurses of patients expressing aggression, irritability, abnormal motor behavior, and hallucination.

    Menthol, the cooling agent in peppermint, is added to almost all commercially available cigarettes. Menthol stimulates olfactory sensations, and interacts with transient receptor potential melastatin 8 (TRPM8) ion channels in cold-sensitive sensory neurons, and transient receptor potential ankyrin 1 (TRPA1), an irritant-sensing channel. It is highly controversial whether menthol in cigarette smoke exerts pharmacological actions affecting smoking behavior. Using plethysmography, we investigated the effects of menthol on the respiratory sensory irritation response in mice elicited by smoke irritants (acrolein, acetic acid, and cyclohexanone). Menthol, at a concentration (16 ppm) lower than in smoke of mentholated cigarettes, immediately abolished the irritation response to acrolein, an agonist of TRPA1, as did eucalyptol (460 ppm), another TRPM8 agonist. Menthol's effects were reversed by a TRPM8 antagonist, AMTB. Menthol's effects were not specific to acrolein, as menthol also attenuated irritation responses to acetic acid, and cyclohexanone, an agonist of the capsaicin receptor, TRPV1. Menthol was efficiently absorbed in the respiratory tract, reaching local concentrations sufficient for activation of sensory TRP channels. These experiments demonstrate that menthol and eucalyptol, through activation of TRPM8, act as potent counterirritants against a broad spectrum of smoke constituents. Through suppression of respiratory irritation, menthol may facilitate smoke inhalation and promote nicotine addiction and smoking-related morbidities.— Willis, D. N., Liu, B., Ha, M.

    The Brøset violence checklist (BVC) is a short-term violence prediction instrument assessing confusion, irritability, boisterousness, verbal threats, physical threats and attacks on objects as either present or absent. The aim of this paper is to describe the evolution and usefulness of the BVC. This paper reviews studies on the BVC and discusses implications for further research. Empirical research has shown that it has moderate sensitivity and high specificity with an adequate inter-rater reliability. The BVC is a useful instrument for predicting inpatient violence within the next 24-h period. The psychometric properties of the instrument are satisfactory. Results from ongoing studies will give important information on cultural differences, the validity of the BVC in less well staffed wards, the clinical use of the checklist and its ability to predict violence throughout all the hospital stay.

    We examined the effectiveness of a variation of noncontingent reinforcement (NCR) that incorporated a stimulus-delay procedure in the reduction of aberrant behavior maintained by positive reinforcement. Functional analyses for three individuals diagnosed with developmental disabilities indicated that their behaviors were maintained by positive reinforcement: one in the form of access to a tangible item, another by attention, and the third by physical contact. We implemented NCR with the delay procedure with two participants using reversal designs to evaluate effects. We also compared this NCR variation and DRO with the third participant to evaluate reinforcer-delivery rates. The variation of NCR was successful in reducing all aberrant behavior to near-zero levels. A comparison of reinforcer delivery between NCR with the stimulus-delay procedure and DRO demonstrated that the participant accessed more reinforcement with NCR. Results are discussed in the context of enhancing decelerative interventions with emphases on minimizing response effort for caregivers and maximizing access to reinforcement for the individuals.

  9. Irritability in Pediatric Patients: Normal or Not?

    2016-01-01

    The goal of this article is to describe the concept of irritability in children and youth, which has been revisited in the DSM-5. Traditionally, this behavior has been more commonly associated with mood disorders, which may account for the rising incidence of bipolar disorder diagnosis and overuse of mood-stabilizing medications in pediatric patients. While not predictive of mania, persistent nonepisodic irritability, if undetected, may escalate to violent behavior with potentially serious outcomes. It is therefore important to educate clinicians about how to accurately assess irritability in pediatric patients. PMID:27486529

    A fundamental trait of the human self is its continuum experience of space and time. Perceptual aberrations of this spatial and temporal continuity is a major characteristic of schizophrenia spectrum disturbances – including schizophrenia, schizotypal personality disorder and schizotypy. We have previously found the classical Perceptual Aberration Scale (PAS) scores, related to body and space, to be positively correlated with both behavior and temporo-parietal activation in healthy participants performing a task involving self-projection in space. However, not much is known about the relationship between temporal perceptual aberration, behavior and brain activity. To this aim, we composed a temporal Perceptual Aberration Scale (tPAS) similar to the traditional PAS. Testing on 170 participants suggested similar performance for PAS and tPAS. We then correlated tPAS and PAS scores to participants' performance and neural activity in a task of self-projection in time. tPAS scores correlated positively with reaction times across task conditions, as did PAS scores. Evoked potential mapping and electrical neuroimaging showed self-projection in time to recruit a network of brain regions at the left anterior temporal cortex, right temporo-parietal junction, and occipito-temporal cortex, and duration of activation in this network positively correlated with tPAS and PAS scores. These data demonstrate that schizotypal perceptual aberrations of both time and space, as reflected by tPAS and PAS scores, are positively correlated with performance and brain activation during self-projection in time in healthy individuals along the schizophrenia spectrum.

    The arrival of the Journal's 175th anniversary occurs at a time of recent advances in research, providing an ideal opportunity to present a neurodevelopmental roadmap for understanding, preventing, and treating psychiatric disorders. Such a roadmap is particularly relevant for early-childhood-onset neurodevelopmental conditions, which emerge when experience-dependent neuroplasticity is at its peak. Employing a novel developmental specification approach, this review places recent neurodevelopmental research on early childhood disruptive behavior within the historical context of the Journal. The authors highlight irritability and callous behavior as two core exemplars of early disruptive behavior. Both phenotypes can be reliably differentiated from normative variation as early as the first years of life. Both link to discrete pathophysiology: irritability with disruptions in prefrontal regulation of emotion, and callous behavior with abnormal fear processing. Each phenotype also possesses clinical and predictive utility. Based on a nomologic net of evidence, the authors conclude that early disruptive behavior is neurodevelopmental in nature and should be reclassified as an early-childhood-onset neurodevelopmental condition in DSM-5. Rapid translation from neurodevelopmental discovery to clinical application has transformative potential for psychiatric approaches of the millennium.

    Development of outcome measures relevant to health nutrition behaviors requires a rigorous process of testing and revision. Whereas researchers often report performance of quantitative data collection to assess questionnaire validity and reliability, qualitative testing procedures are often overlooked. This report outlines a procedure for assessing face validity of a Spanish-language dietary assessment tool. Reviewing the literature produced no rigorously validated Spanish-language food behavior assessment tools for the US Department of Agriculture’s food assistance and education programs. In response to this need, this study evaluated the face validity of a Spanish-language food behavior checklist adapted from a 16-item English version of a food behavior checklist shown to be valid and reliable for limited-resource English speakers. The English version was translated using rigorous methods involving initial translation by one party and creation of five possible versions. Photos were modified based on client input and new photos were taken as necessary. A sample of low-income, Spanish-speaking women completed cognitive interviews (n=20). Spanish translation experts (n=7) fluent in both languages and familiar with both cultures made minor modifications but essentially approved client preferences. The resulting checklist generated a readability score of 93, indicating low reading difficulty. The Spanish-language checklist has adequate face validity in the target population and is ready for further validation using convergent measures. At the conclusion of testing, this instrument may be used to evaluate nutrition education interventions in California. These qualitative procedures provide a framework for designing evaluation tools for low-literate audiences participating in the US Department of Agriculture food assistance and education programs.

    A long delay between the first registered symptoms of autism spectrum disorder and a final diagnosis has been reported. The reasons for this are the spare use of specialized autism instruments, missing clinical expertise, and the late referral to specialized centers in primary care. Previous studies recommending the Child Behavior Checklist 1.5-5 for screening have requested additional research. A total of 183 children aged 25-71 months participated in this study. The Child Behavior Checklist scales of 80 children with autism spectrum disorder were compared with 103 children diagnosed with other psychiatric disorders. In the logistic regression analysis, the Withdrawn and Pervasive Developmental Problems Child Behavior Checklist scales with a significant predictive value of risk for an autism spectrum disorder diagnosis were identified. The optimal cutoff points T = 64.5 on the Pervasive Developmental Problems scale (area under the curve = 0.781, sensitivity = 0.83, specificity = 0.60, positive predictive value = 0.62, negative predictive value = 0.82, odds ratio = 7) and T = 60.5 on the Withdrawn scale (area under the curve = 0.809, sensitivity = 0.88, specificity = 0.63, positive predictive value = 0.65, negative predictive value = 0.87, odds ratio = 12) were evaluated in the receiver operating characteristics analysis. The present study confirms the utility of the German version of the Child Behavior Checklist 1.5-5 as a level 1 screening tool to identify children with a risk of autism spectrum disorder; however, a risk of over-identifying should be considered. The Child Behavior Checklist 1.5-5 can complement the pediatric examination as a quick and cost-effective questionnaire.

  1. Bowel urgency in patients with irritable bowel syndrome.

    2007-01-01

    Bowel urgency is the most bothersome symptom in irritable bowel syndrome patients with diarrhea, but its pathophysiology is poorly understood. Our aim was to assess the relationships among reporting the symptom, the reservoir functions of the colon and rectum, and the patients' psychologic profile. The study involved 28 consecutive patients with irritable bowel syndrome and 17 healthy subjects. The presence or absence of bowel urgency was verified by means of a questionnaire during the 3 days required for the ingestion of radio-opaque markers. On the fourth day, an abdominal x-ray was taken to assess colonic transit time, and rectal sensory and motor responses were measured during rectal distention. The subjects' psychologic profiles were assessed using a psychologic symptoms checklist. Forty-six percent of the patients reported urgency associated with at least 1 defecation. The multivariate logistic regression analysis showed that colonic transit was the only variable independently associated with reported bowel urgency, but the threshold for the sensation of urgency was not removed from the model since its borderline significance level. Rectal compliance was closely associated with the threshold for the sensation of urgency during rectal distention but was not an independent factor for reporting the sensation. The patients with and without urgency showed altered psychologic profiles. The symptom of urgency is associated with objective alterations in the colonic and rectal reservoir of patients with irritable bowel syndrome.

    BACKGROUND- Children with Autism Spectrum Disorder (ASD) demonstrate a physiological imbalance between free radicals, resultant from oxidative stress, and antioxidants. Oxidative stress is linked to the pathogenesis of this neurocognitive disorder. The aim of this pilot feasibility study was to examine the effect of consumption of high concentration antioxidant cacao on behavior of children with ASD. METHODS- This was a 4-week pre-test post-test experimental pilot study of high antioxidant cacao and children with ASD. Participants consumed 8 squares (or 16 grams) per day of the dark chocolate which had a concentration of 70% cacao and 30% organic cane sugar (total antioxidant concentration was 8,320). The two main behavioral measures were the Aberrant Behavior Checklist- 2nd Edition and the Autism Spectrum Rating Scale which were completed by the child's teacher at baseline and end of week four. RESULTS- Sixteen participants were recruited for this study. Follow up data was available on 12 participants (9 males, 3 females, mean age of 10.9 ±3.9 years). Significant improvements on the Autism Spectrum Rating Scale were noted in Social/Communication (p=0.03, η2=0.79), Unusual Behaviors (p=0.02, η2=0.70), and Self-Regulation (p=0.04, η2=0.59). No significant changes were noted on any of the Aberrant Behavior Checklist-2 subscales (p>.05). CONCLUSION- Results from this study support the potential therapeutic benefit of antioxidants in improving social communication, unusual behaviors, and self-regulation behaviors of children with ASD. Further robust randomized controlled trials are now necessary to elaborate the validity of these findings.

    The diagnostic validity of autism spectrum disorder (ASD) based on Diagnostic and Statistical Manual of Mental Disorders (DSM) has been challenged in Down syndrome (DS), because of the high prevalence of cognitive impairments in this population. Therefore, we attempted to validate DSM-based diagnoses via an unbiased categorisation of participants with a DSM-independent behavioural instrument. Based on scores on the Aberrant Behaviour Checklist - Community, we performed sequential factor (four DS-relevant factors: Autism-Like Behaviour, Disruptive Behaviour, Hyperactivity, Self-Injury) and cluster analyses on a 293-participant paediatric DS clinic cohort. The four resulting clusters were compared with DSM-delineated groups: DS + ASD, DS + None (no DSM diagnosis), DS + DBD (disruptive behaviour disorder) and DS + SMD (stereotypic movement disorder), the latter two as comparison groups. Two clusters were identified with DS + ASD: Cluster 1 (35.1%) with higher disruptive behaviour and Cluster 4 (48.2%) with more severe autistic behaviour and higher percentage of late onset ASD. The majority of participants in DS + None (71.9%) and DS + DBD (87.5%) were classified into Cluster 2 and 3, respectively, while participants in DS + SMD were relatively evenly distributed throughout the four clusters. Our unbiased, DSM-independent analyses, using a rating scale specifically designed for individuals with severe intellectual disability, demonstrated that DSM-based criteria of ASD are applicable to DS individuals despite their cognitive impairments. Two DS + ASD clusters were identified and supported the existence of at least two subtypes of ASD in DS, which deserve further characterisation. Despite the prominence of stereotypic behaviour in DS, the SMD diagnosis was not identified by cluster analysis, suggesting that high-level stereotypy is distributed throughout DS. Further supporting DSM diagnoses, typically behaving DS participants were easily distinguished as a group from

    The level of parental stress in families of children with autism and other developmental disabilities and its association with child comorbid symptoms was studied in an ethnically diverse population, in a cross-sectional study with structured interview. The sample included 50 families of children with autism and 50 families of children with other developmental disabilities, matched by age/gender. Interview included Parenting Stress Index-Short Form, Gastrointestinal Questionnaire, Child Sleep Habits Questionnaire, and Aberrant Behavior Checklist. In this ethnically diverse sample, parental stress was significantly higher for the autism group and for non-Hispanic and US-born mothers. In both study groups, parental stress was related to child irritability. Parental stress was also related to gastrointestinal problems in the autism group and to sleep difficulties in the developmental disabilities group. Targeting child irritability may be particularly important in reducing parental stress for families of children with autism and other developmental disabilities. © The Author(s) 2015.

    Despite many studies about the association between caregiver burden and behavioral and psychological symptoms of dementia (BPSD), there have been no population-based studies to evaluate caregiver burden associated with each BPSD. To evaluate caregiver burden associated with the individual BPSD in elderly people living in the community. The subjects were 67 participants with dementia living with their caregivers (diagnosed in the third Nakayama study): 51 Alzheimer's disease, 5 vascular dementia and 11 other. The Neuropsychiatric Inventory (NPI) and NPI Caregiver Distress Scale (NPI-D) were used to assess subjects' BPSD and related caregiver distress, respectively. In the subjects exhibiting BPSD, aberrant motor behavior had the highest mean NPI score, and depression/dysphoria had the lowest. Agitation/aggression had the highest mean NPI-D score, and euphoria/elation had the lowest. Delusion, agitation/aggression, apathy/indifference, irritability/lability and aberrant motor behavior showed a correlation between the NPI and NPI-D scores. The burden associated with BPSD is different for each symptom and does not always depend on frequency and severity of BPSD. These findings suggest that some symptoms, such as agitation/aggression and irritability/lability, may affect the caregivers significantly, although their frequency and severity are low.

    Behavioral and psychological symptoms in dementia (BPSD) are important predictors of institutionalization as well as caregiver burden and depression. Previous reviews have tended to group BPSD as one category with little focus on the role of the individual symptoms. This review investigates the role of the individual symptoms of BPSD in relation to the impact on different measures of family caregiver well-being. Systematic review and meta-analysis of papers published in English between 1980 and December 2015 reporting which BPSD affect caregiver well-being. Paper quality was appraised using the Downs and Black Checklist (1998). Forty medium and high quality quantitative papers met the inclusion criteria, 16 were suitable to be included in a meta-analysis of mean distress scores. Depressive behaviors were the most distressing for caregivers followed by agitation/aggression and apathy. Euphoria was the least distressing. Correlation coefficients between mean total behavior scores and mean distress scores were pooled for four studies. Irritability, aberrant motor behavior and delusions were the most strongly correlated to distress, disinhibition was the least correlated. The evidence is not conclusive as to whether some BPSD impact caregiver well-being more than others. Studies which validly examined BPSD individually were limited, and the included studies used numerous measures of BPSD and numerous measures of caregiver well-being. Future research may benefit from a consistent measure of BPSD, examining BPSD individually, and by examining the causal mechanisms by which BPSD impact well-being by including caregiver variables so that interventions can be designed to target BPSD more effectively.

    To test the efficacy of venlafaxine at a dose of 18.75 mg/day on the reduction of behavioral problems such as irritability and hyperactivity/noncompliance in patients with intellectual disabilities and autism spectrum disorder (ASD). Our secondary hypothesis was that the usual doses of zuclopenthixol and/or clonazepam would decrease in the venlafaxine-treated group. In a randomized double-blind study, we compared six patients who received venlafaxine along with their usual treatment (zuclopenthixol and/or clonazepam) with seven patients who received placebo plus usual care. Irritability, hyperactivity/noncompliance, and overall clinical improvement were measured after 2 and 8 weeks, using validated clinical scales. Univariate analyses showed that the symptom of irritability improved in the entire sample (p = 0.023 after 2 weeks, p = 0.061 at study endpoint), although no difference was observed between the venlafaxine and placebo groups. No significant decrease in hyperactivity/noncompliance was observed during the study. At the end of the study, global improvement was observed in 33% of participants treated with venlafaxine and in 71% of participants in the placebo group (p = 0.29). The study found that decreased cumulative doses of clonazepam and zuclopenthixol were required for the venlafaxine group. Multivariate analyses (principal component analyses) with at least three combinations of variables showed that the two populations could be clearly separated (p b 0.05). Moreover, in all cases, the venlafaxine population had lower values for the Aberrant Behavior Checklist (ABC), Behavior Problems Inventory (BPI), and levels of urea with respect to the placebo group. In one case, a reduction in the dosage of clonazepam was also suggested. For an additional set of variables (ABC factor 2, BPI frequency of aggressive behaviors, hematic ammonia at Day 28, and zuclopenthixol and clonazepam intake), the separation between the two samples was statistically significant as

    To clarify the health risks related to silver nanoparticles (Ag-NPs), we evaluated the genotoxicity, acute oral and dermal toxicity, eye irritation, dermal irritation and corrosion and skin sensitisation of commercially manufactured Ag-NPs according to the OECD test guidelines and GLP. The Ag-NPs were not found to induce genotoxicity in a bacterial reverse mutation test and chromosomal aberration test, although some cytotoxicity was observed. In acute oral and dermal toxicity tests using rats, none of the rats showed any abnormal signs or mortality at a dose level of ∼ 2000 mg/kg. Similarly, acute eye and dermal irritation and corrosion tests using rabbits revealed no significant clinical signs or mortality and no acute irritation or corrosion reaction for the eyes and skin. In a skin sensitisation test using guinea pigs, one animal (1/20) showed discrete or patchy erythema, thus Ag-NPs can be classified as a weak skin sensitiser.

    Although the aircraft checklist has long been regarded as the foundation of pilot standardization and cockpit safety, it has escaped the scrutiny of the human factors profession. The improper use, or the non-use, of the normal checklist by flight crews is often cited as the probable cause or at least a contributing factor to aircraft accidents. An attempt is made to analyze the normal checklist, its functions, format, design, length, usage, and the limitations of the humans who must interact with it. The development of the checklist from the certification of a new model to its delivery and use by the customer are discussed. The influence of the government, particularly the FAA Principle Operations Inspector, the manufacturer's philosophy, the airline's culture, and the end user, the pilot, influence the ultimate design and usage of this device. The effects of airline mergers and acquisitions on checklist usage and design are noted. In addition, the interaction between production pressures and checklist usage and checklist management are addressed. Finally, a list of design guidelines for normal checklists is provided.

    Autism is a neurodevelopmental disorder that causes significant impairment in socialization and communication. It is also associated with ritualistic and stereotypical behaviour. Recent studies propose both hyper-and hypoglutamatergic ideologies for autism. The objective of this study was to assess the effects of memantine plus risperidone in the treatment of children with autism. Children with autism were randomly allocated to risperidone plus memantine or placebo plus risperidone for a 10-wk, double-blind, placebo-controlled study. The dose of risperidone was titrated up to 3 mg/d and memantine was titrated to 20 mg/d. Children were assessed at baseline and after 2, 4, 6, 8 and 10 wk of starting medication protocol. The primary outcome measure was the irritability subscale of Aberrant Behavior Checklist-Community (ABC-C). Difference between the two treatment arms was significant as the group that received memantine had greater reduction in ABC-C subscale scores for irritability, stereotypic behaviour and hyperactivity. Eight side-effects were observed over the trial, out of the 25 side-effects that the checklist included. The difference between the two groups in the frequency of side-effects was not significant. The present study suggests that memantine may be a potential adjunctive treatment strategy for autism and it was generally well tolerated. This trial is registered with the Iranian Clinical Trials Registry (IRCT1138901151556N10; www.irct.ir).

    Previous studies have identified the behavioral responses of Aedes aegypti to irritant and repellent chemicals that can be exploited to reduce man-vector contact. Maximum efficacy of interventions based on irritant chemical actions will, however, require full knowledge of variables that influence vector resting behavior and how untreated "safe sites" contribute to overall impact. Using a laboratory box assay, resting patterns of two population strains of female Ae. aegypti (THAI and PERU) were evaluated against two material types (cotton and polyester) at various dark:light surface area coverage (SAC) ratio and contrast configuration (horizontal and vertical) under chemical-free and treated conditions. Chemicals evaluated were alphacypermethrin and DDT at varying concentrations. Under chemical-free conditions, dark material had significantly higher resting counts compared to light material at all SAC, and significantly increased when material was in horizontal configuration. Cotton elicited stronger response than polyester. Within the treatment assays, significantly higher resting counts were observed on chemical-treated dark material compared to untreated light fabric. However, compared to matched controls, significantly less resting observations were made on chemical-treated dark material overall. Most importantly, resting observations on untreated light material (or "safe sites") in the treatment assay did not significantly increase for many of the tests, even at 25% SAC. Knockdown rates were ≤5% for all assays. Significantly more observations of flying mosquitoes were made in test assays under chemical-treatment conditions as compared to controls. When preferred Ae. aegypti resting sites are treated with chemicals, even at reduced treatment coverage area, mosquitoes do not simply move to safe sites (untreated areas) following contact with the treated material. Instead, they become agitated, using increased flight as a proxy indicator. It is this contact

    Background An imbalance in the excitatory/inhibitory systems with abnormalities in the glutamatergic pathways has been implicated in the pathophysiology of autism. Furthermore, chronic redox imbalance was also recently linked to this disorder. The goal of this pilot study was to assess the feasibility of using oral N-acetylcysteine (NAC), a glutamatergic modulator and an antioxidant in the treatment of behavioral disturbance in children with autism. Methods This is a 12-week, double-blind, randomized, placebo-controlled study of NAC in children with autistic disorder. Subjects randomized to NAC were initiated at 900 mg daily for 4 weeks, then 900 mg twice-daily for 4 weeks and 900 mg three-times-daily for 4 weeks. The primary behavioral measure (Aberrant Behavior ChecklistIrritability subscale) and safety measures were performed at baseline, 4, 8, and 12 weeks. Secondary measures included the ABC-Stereotypy subscale, Repetitive Behavior Scale – Revised (RBS-R), and Social Responsiveness Scale (SRS). Results Thirty-three subjects (31 males, 2 females; aged 3.2–10.7 years) were randomized in the study. Follow-up data was available on fourteen subjects in the NAC group and fifteen in the placebo group. Oral NAC was well-tolerated with limited side effects. Compared to placebo, NAC resulted in significant improvements on ABC-Irritability subscale (F=6.80; p<.001; d=.96). Conclusions Data from this pilot investigation support the potential usefulness of NAC for treating irritability in children with autistic disorder. Large randomized controlled investigations are warranted. ClinicalTrials.gov Identifier NCT00627705 PMID:22342106

    Depression is a prevalent psychiatric disorder associated with significant personal and societal burden. There is accumulating evidence for the presence of a subtype of depression characterized by the presence of irritability that is associated with increased morbidity, risk for suicidal ideation, and functional impairments in adults. Little is known about the features of depressive symptoms with and without irritability among young adults in college. The primary aim of this study was to characterize the presentation of college students with depressive symptoms and irritability. Two-hundred eighty-seven undergraduate college students with depressive symptoms with and without irritability were compared across several psychiatric and functional outcome variables. Independent samples t-tests or logistic regressions were conducted for each outcome variable using the irritability item of the Beck Depression Inventory as a dichotomous grouping variable. Analyses were conducted separately for the men and the women. Both male and female students with depressive symptoms and severe irritability reported a greater severity of depressive symptoms compared with their peers with no or mild irritability. In the women, the presence of irritability was associated with greater symptoms of anxiety, whereas in the men, it was associated with increased likelihood of engaging in risky behaviors, including compulsive use of alcohol, illicit drugs, and prescription drugs. The male and female college students with depressive symptoms with and without irritability did not differ on severity of suicidal ideation, hopelessness, or cognitive functioning. The findings from this study suggest that depressive symptoms and irritability may characterize a subtype of college students who have a greater symptom burden and with the potential need for more aggressive and prompt treatment.

    Background and aims While the association between health anxiety and maladaptive Internet use is a well-established finding, no studies have been performed to examine the possible effect of abnormal illness behavior (AIB). AIB is a maladaptive manner of experiencing, evaluating, or acting in response to health and illness that is disproportionate to evident pathology. The aim of this study was to investigate the association between AIB and Internet addiction (IA) severity in a sample of Italian University students. The possible effect of alexithymia, anxiety, and depression was also taken into account. Methods Participants were 115 men and 163 women (mean age = 23.62 ± 4.38 years); AIB was measured via the Illness Behavior Questionnaire (IBQ), and IA severity by the Internet Addiction Test (IAT). Results The most powerful IBQ factor predicting IA severity scores was disease conviction. Irritability was the only emotional IBQ factor associated with IA severity. Nevertheless, disease conviction and alexithymia remained the only significant predictors of IAT scores when hierarchical regression analysis was executed. Discussion and conclusions Our results support previous findings showing that those characterized by health anxiety are more prone to an excessive and maladaptive use of Internet. Moreover, this study showed that irritability was the only emotional aspect of AIB predicting IA severity. This finding is consistent with the cognitive model of hypochondria, which states that cognitive factors (dysfunctional beliefs and assumptions) play a major role in the explanation of this psychopathological condition.

    Introduction The study aims to investigate two kinds of treatment in patients suffering from irritable bowel syndrome (IBS) and consequently compares its efficacy on improving the symptoms and mental health of patients; one with just medical treatment and another through a combination of psychotherapy and medical treatment. Material and methods Applying general sampling, 50 IBS patients were selected from among those who used to refer to a Gastroenterology Clinic. After physical and mental evaluations based on ROME-II scale and SCL-90-R questionnaires, the subjects were randomly superseded into: the control group with medical treatment and, the case group with a combination of medical and psychological treatments. The acquired data were then analyzed through t-test and Mann-Whitney U-test. Results The findings show that the mental health of patients receiving cognitive behavioral therapy along with the medical treatment was higher than those of the control group at post-test level. It was observed that the therapy reduces the disability caused by IBS. Comparatively, while the cognitive therapy and medical treatments cured 80% of the patients, those receiving cognitive therapy alone showed an extensive reduction of symptoms. Conclusions Considering the role of cognitive behavioral therapy, it is therefore recommend that such patients be managed by a combined team of gastroenterologists and psychologists. PMID:22457686

  9. Nodal aberration theory applied to freeform surfaces

    When new three-dimensional packages are developed for imaging optical systems, the rotational symmetry of the optical system is often broken, changing its imaging behavior and making the optical performance worse. A method to restore the performance is to use freeform optical surfaces that compensate directly the aberrations introduced from tilting and decentering the optical surfaces. In order to effectively optimize the shape of a freeform surface to restore optical functionality, it is helpful to understand the aberration effect the surface may induce. Using nodal aberration theory the aberration fields induced by a freeform surface in an optical system are explored. These theoretical predications are experimentally validated with the design and implementation of an aberration generating telescope.

    Irritable and oppositional behaviors are increasingly considered as distinct dimensions of oppositional defiant disorder. However, few studies have explored this multidimensionality across the broader spectrum of disruptive behavior problems (DBPs). This study examined the presence of dimensions and distinct subgroups of childhood DBPs, and the cross-sectional and longitudinal associations between these dimensions. Using factor mixture models (FMMs), the presence of dimensions and subgroups of DBPs was assessed in the Generation R Study at ages 6 (n = 6,209) and 10 (n = 4,724) years. Replications were performed in two population-based cohorts (Netherlands Twin Registry, n = 4,402, and Swedish Twin Study of Child and Adolescent Development, n = 1,089) and a clinical sample (n = 1,933). We used cross-lagged modeling in the Generation R Study to assess cross-sectional and longitudinal associations between dimensions. DBPs were assessed using mother-reported responses to the Child Behavior Checklist. Empirically obtained dimensions of DBPs were oppositional behavior (age 6 years), disobedient behavior, rule-breaking behavior (age 10 years), physical aggression, and irritability (both ages). FMMs suggested that one-class solutions had the best model fit for all dimensions in all three population-based cohorts. Similar results were obtained in the clinical sample. All three dimensions, including irritability, predicted subsequent physical aggression (range, 0.08-0.16). This study showed that childhood DBPs should be regarded as a multidimensional phenotype rather than comprising distinct subgroups. Incorporating multidimensionality will improve diagnostic accuracy and refine treatment. Future studies need to address the biological validity of the DBP dimensions observed in this study; herein lies an important opportunity for neuroimaging and genetic measures.

    A Child Behavior Checklist (CBCL) profile defined as Dysregulation Profile (DP) (scores 2 standard deviations or more in anxiety/depression, aggression, attention subscales) has been correlated to poor emotional and behavioral self-regulation. The clinical meaning and the prognostic implications of CBCL-DP are still debated, although it seems associated with severe psychopathology and poor adjustment. In the present study, we used the CBCL-DP score to examine the adolescent outcomes (psychiatric diagnosis, substance use, psychiatric hospitalization) in 80 referred children with disruptive behavior disorders -DBD- (Oppositional Defiant Disorder or conduct disorder), aged 8-9 years, 72 males (90%) and 8 females (10%), followed-up until the age of 14-15 years. Children with higher score on the CBCL-DP profile were at increased risk for presenting ADHD and mood disorders in adolescence. While ADHD in adolescence was predicted also by an ADHD diagnosis during childhood, CBCL-DP score was the only significant predictor of a mood disorder at 14-15 years. On the contrary, CBCL-DP score was not associated with a higher risk of conduct disorder, substance use and hospitalizations in adolescence. A cost-effective and reliable diagnostic measure such as the CBCL may be a part of the diagnostic procedure aimed to capture these at-risk children, to monitor their natural history up to adolescence, and to prevent the risk of a full-blown mood disorder. The small sample size and a selection bias of severe patients with DBD limit the generalization of the findings. Copyright © 2015 Elsevier B.V. All rights reserved.

    2002-01-01

    Background Agave tequilana Weber var. azul, is the only one variety permitted by federal law in México to be used for tequila production which is the most popular contemporary alcoholic beverage made from agave and recognized worldwide. Despite the economic, genetic, and ornamental value of the plant, it has not been subjected to detailed cytogenetic research, which could lead to a better understanding of its reproduction for future genetic improvement. The objective of this work was to study the meiotic behavior in pollen mother cells and its implications on the pollen viability in Agave tequilana Weber var. azul. Results The analysis of Pollen Mother Cells in anaphase I (A-I) showed 82.56% of cells with a normal anaphase and, 17.44% with an irregular anaphase. In which 5.28% corresponded to cells with side arm bridges (SAB); 3.68% cells with one bridge and one fragment; 2.58% of irregular anaphase showed cells with one or two lagging chromosomes and 2.95% showed one acentric fragment; cells with two bridges and cells with two bridges and one acentric fragment were observed in frequencies of 1.60% and 1.35% respectively. In anaphase II some cells showed bridges and fragments too. Aberrant A-I cells had many shrunken or empty pollen grains (42.00%) and 58.00 % viable pollen. Conclusion The observed meiotic irregularities suggest that structural chromosome aberrations have occurred, such as heterozygous inversions, sister chromatid exchanges, deletions and duplications which in turn are reflected in a low pollen viability.

    Abstract Objective The objective of this research was to explore the effects of risperidone on cognitive processes in children with autism and irritable behavior. Method Thirty-eight children, ages 5–17 years with autism and severe behavioral disturbance, were randomly assigned to risperidone (0.5 to 3.5 mg/day) or placebo for 8 weeks. This sample of 38 was a subset of 101 subjects who participated in the clinical trial; 63 were unable to perform the cognitive tasks. A double-blind placebo-controlled parallel groups design was used. Dependent measures included tests of sustained attention, verbal learning, hand-eye coordination, and spatial memory assessed before, during, and after the 8-week treatment. Changes in performance were compared by repeated measures ANOVA. Results Twenty-nine boys and 9 girls with autism and severe behavioral disturbance and a mental age ≥18 months completed the cognitive part of the study. No decline in performance occurred with risperidone. Performance on a cancellation task (number of correct detections) and a verbal learning task (word recognition) was better on risperidone than on placebo (without correction for multiplicity). Equivocal improvement also occurred on a spatial memory task. There were no significant differences between treatment conditions on the Purdue Pegboard (hand-eye coordination) task or the Analog Classroom Task (timed math test). Conclusion Risperidone given to children with autism at doses up to 3.5 mg for up to 8 weeks appears to have no detrimental effect on cognitive performance. PMID:18582177

  18. Influence of coma aberration on aperture averaged scintillations in oceanic turbulence

    2018-01-01

    The influence of coma aberration on aperture averaged scintillations in oceanic turbulence is studied in detail by using the numerical simulation method. In general, in weak oceanic turbulence, the aperture averaged scintillation can be effectively suppressed by means of the coma aberration, and the aperture averaged scintillation decreases as the coma aberration coefficient increases. However, in moderate and strong oceanic turbulence the influence of coma aberration on aperture averaged scintillations can be ignored. In addition, the aperture averaged scintillation dominated by salinity-induced turbulence is larger than that dominated by temperature-induced turbulence. In particular, it is shown that for coma-aberrated Gaussian beams, the behavior of aperture averaged scintillation index is quite different from the behavior of point scintillation index, and the aperture averaged scintillation index is more suitable for characterizing scintillations in practice.

  20. Commentary: Reducing diagnostic errors: another role for checklists?

    Diagnostic errors are a widespread problem, although the true magnitude is unknown because they cannot currently be measured validly. These errors have received relatively little attention despite alarming estimates of associated harm and death. One promising intervention to reduce preventable harm is the checklist. This intervention has proven successful in aviation, in which situations are linear and deterministic (one alarm goes off and a checklist guides the flight crew to evaluate the cause). In health care, problems are multifactorial and complex. A checklist has been used to reduce central-line-associated bloodstream infections in intensive care units. Nevertheless, this checklist was incorporated in a culture-based safety program that engaged and changed behaviors and used robust measurement of infections to evaluate progress. In this issue, Ely and colleagues describe how three checklists could reduce the cognitive biases and mental shortcuts that underlie diagnostic errors, but point out that these tools still need to be tested. To be effective, they must reduce diagnostic errors (efficacy) and be routinely used in practice (effectiveness). Such tools must intuitively support how the human brain works, and under time pressures, clinicians rarely think in conditional probabilities when making decisions. To move forward, it is necessary to accurately measure diagnostic errors (which could come from mapping out the diagnostic process as the medication process has done and measuring errors at each step) and pilot test interventions such as these checklists to determine whether they work.

    Objective: To evaluate the reliability and validity of warning signs checklist developed by the National Health and Family Planning Commission of the People's Republic of China (NHFPC), so as to determine the screening effectiveness of warning signs on developmental problems of early childhood. Method: Stratified random sampling method was used to assess the reliability and validity of checklist of warning sign and 2 110 children 0 to 6 years of age(1 513 low-risk subjects and 597 high-risk subjects) were recruited from 11 provinces of China. The reliability evaluation for the warning signs included the test-retest reliability and interrater reliability. With the use of Age and Stage Questionnaire (ASQ) and Gesell Development Diagnosis Scale (GESELL) as the criterion scales, criterion validity was assessed by determining the correlation and consistency between the screening results of warning signs and the criterion scales. Result: In terms of the warning signs, the screening positive rates at different ages ranged from 10.8%(21/141) to 26.2%(51/137). The median (interquartile) testing time for each subject was 1(0.6) minute. Both the test-retest reliability and interrater reliability of warning signs reached 0.7 or above, indicating that the stability was good. In terms of validity assessment, there was remarkable consistency between ASQ and warning signs, with the Kappa value of 0.63. With the use of GESELL as criterion, it was determined that the sensitivity of warning signs in children with suspected developmental delay was 82.2%, and the specificity was 77.7%. The overall Youden index was 0.6. Conclusion: The reliability and validity of warning signs checklist for screening early childhood developmental problems have met the basic requirements of psychological screening scales, with the characteristics of short testing time and easy operation. Thus, this warning signs checklist can be used for screening psychological and behavioral problems of early childhood

    Objective Clinically impairing irritability affects 25% to 45% of children with attention-deficit/hyperactivity disorder (ADHD); yet, we know little about what interventions are effective in treating children with ADHD and co-occurring irritability. We used data from the Multimodal Treatment Study of Children With ADHD (MTA) to address 3 aims: to establish whether irritability in children with ADHD can be distinguished from other symptoms of oppositional defiant disorder (ODD); to examine whether ADHD treatment is effective in treating irritability; and to examine how irritability influences ADHD treatment outcomes. Method Secondary analyses of data from the MTA included multivariate analyses, and intent-to-treat random-effects regression models were used. Results Irritability was separable from other ODD symptoms. For treating irritability, systematic stimulant treatment was superior to behavioral management but not to routine community care; a combination of stimulants and behavioral treatment was superior to community care and to behavioral treatment alone, but not to medication alone. Irritability did not moderate the impact of treatment on parent- and teacher-reported ADHD symptoms in any of the 4 treatment groups. Conclusion Treatments targeting ADHD symptoms are helpful for improving irritability in children with ADHD. Moreover, irritability does not appear to influence the response to treatment of ADHD.

    Behavioral problems such as disinhibition, irritability, restlessness, distractibility, and aggression are common after acquired brain injury (ABI). The persistence and severity of these problems impair the brain-injured individual's reintegration into family, school, and community life. Since the early 1980s, behavior analysis and therapy have been used to address the behavioral sequelae of ABI. These interventions are based on principles of learning and behavior that have been robustly successful when applied across a broad range of other clinical populations. Most of the research on behavioral treatment after ABI has involved clinical case studies or studies employing single-subject experimental designs across a series of cases. The literature supports the effectiveness of these interventions across ages, injury severities, and stages of recovery after ABI. Recommended guidelines for behavior management include: direct behavioral observations, systematic assessment of environmental and within-patient variables associated with aberrant behavior, antecedent management to minimize the probability of aberrant behavior, provision of functionally equivalent alternative means of controlling the environment, and differential reinforcement to shape positive behavior and coping strategies while not inadvertently shaping emergent, disruptive sequelae. This package of interventions requires direction by a highly skilled behavioral psychologist or therapist who systematically monitors target behavior to evaluate progress and guide treatment decisions. A coordinated multisite effort is needed to design intervention protocols that can be studied prospectively in randomized controlled trials. However, there will continue to be an important role for single subject experimental design for studying the results of individualized interventions and obtaining pilot data to guide subsequent randomized controlled trails.

    The present study investigated whether children with ADHD and those with working memory impairments have a common behavioral profile in the classroom. Three teacher checklists were used: the Conners' teacher rating scale (CTRS), the behavior rating inventory of executive function (BRIEF), and the working memory rating scale. The Conners' continuous performance test (CPT) was also included to determine whether there is a correspondence between performance on this widely used cognitive measure of attention deficits and teacher ratings of classroom behavior. All three behavior scales, but not the CPT, were able to successfully discriminate children with ADHD and those with working memory deficits from typically-developing children. Both the CTRS and the BRIEF discriminated a significant proportion of the children with ADHD from those with working memory deficits, indicating that while both groups exhibit behavioral problems in the classroom, they are characterized by differential attention profiles. The children with ADHD were identified on the basis of oppositional and hyperactive behavior, while those with working memory deficits were more inattentive.

    2016-10-01

    Nodal Aberration Theory (NAT) was used to calculate the zero field position in Full Field Display (FFD) for the given aberration term. Aiming at wide-filed non-rotational symmetric decentered optical systems, we have presented the nodal geography behavior of the family of third-order and fifth-order aberrations. Meanwhile, we have calculated the wavefront aberration expressions when one optical element in the system is tilted, which was not at the entrance pupil. By using a three-piece-cellphone lens example in optical design software CodeV, the nodal geography is testified under several situations; and the wavefront aberrations are calculated when the optical element is tilted. The properties of the nodal aberrations are analyzed by using Fringe Zernike coefficients, which are directly related with the wavefront aberration terms and usually obtained by real ray trace and wavefront surface fitting.

    In this study we compared 33 IQ and age matched pairs of individuals with Aspergers Disorder (ASP) and high functioning autism (HFA) on measures of repetitive behavior. On the Repetitive Behavior Scale-Revised (RBS-R), the ASP and HFA groups showed no differences in RBS-R Intensity score (severity) score or Frequency score (number of problems present). This suggests that the two groups are similar with respect to the intensity or severity of repetitive behaviors and the presence of repetitive behaviors. At the item level there were no differences on scales typically associated with autism (Stereotyped Behavior) and ASP (Restricted Interests). Similarly, there were no differences between the groups on the Aberrant Behavior Checklist Stereotypy scale. These findings add to the body of literature showing that HFA and ASP fail to differ with respect to repetitive behaviors. The implications of the findings for neurobiologic and genetic studies are discussed.

  11. Theory of aberration fields for general optical systems with freeform surfaces.

    PubMed

    Fuerschbach, Kyle; Rolland, Jannick P; Thompson, Kevin P

    2014-11-03

    This paper utilizes the framework of nodal aberration theory to describe the aberration field behavior that emerges in optical systems with freeform optical surfaces, particularly φ-polynomial surfaces, including Zernike polynomial surfaces, that lie anywhere in the optical system. If the freeform surface is located at the stop or pupil, the net aberration contribution of the freeform surface is field constant. As the freeform optical surface is displaced longitudinally away from the stop or pupil of the optical system, the net aberration contribution becomes field dependent. It is demonstrated that there are no new aberration types when describing the aberration fields that arise with the introduction of freeform optical surfaces. Significantly it is shown that the aberration fields that emerge with the inclusion of freeform surfaces in an optical system are exactly those that have been described by nodal aberration theory for tilted and decentered optical systems. The key contribution here lies in establishing the field dependence and nodal behavior of each freeform term that is essential knowledge for effective application to optical system design. With this development, the nodes that are distributed throughout the field of view for each aberration type can be anticipated and targeted during optimization for the correction or control of the aberrations in an optical system with freeform surfaces. This work does not place any symmetry constraints on the optical system, which could be packaged in a fully three dimensional geometry, without fold mirrors.

    Centrosomes are the main microtubule-organizing centers of animal cells. Although centrosome aberrations are common in tumors, their consequences remain subject to debate. Here, we studied the impact of structural centrosome aberrations, induced by deregulated expression of ninein-like protein (NLP), on epithelial spheres grown in Matrigel matrices. We demonstrate that NLP-induced structural centrosome aberrations trigger the escape ("budding") of living cells from epithelia. Remarkably, all cells disseminating into the matrix were undergoing mitosis. This invasive behavior reflects a novel mechanism that depends on the acquisition of two distinct properties. First, NLP-induced centrosome aberrations trigger a re-organization of the cytoskeleton, which stabilizes microtubules and weakens E-cadherin junctions during mitosis. Second, atomic force microscopy reveals that cells harboring these centrosome aberrations display increased stiffness. As a consequence, mitotic cells are pushed out of mosaic epithelia, particularly if they lack centrosome aberrations. We conclude that centrosome aberrations can trigger cell dissemination through a novel, non-cell-autonomous mechanism, raising the prospect that centrosome aberrations contribute to the dissemination of metastatic cells harboring normal centrosomes. © 2018 The Authors.

  13. Efficacy and Tolerability of Pharmacotherapy Options for the Treatment of Irritability in Autistic Children

    2014-01-01

    Children with autism have a high rate of irritability and aggressive symptoms. Irritability or self-injurious behavior can result in significant harm to those affected, as well as to marked distress for their families. This paper provides a literature review regarding the efficacy and tolerability of pharmacotherapy for the treatment of irritability in autistic children. Although antipsychotics have not yet been approved for the treatment of autistic children by many countries, they are often used to reduce symptoms of behavioral problems, including irritability, aggression, hyperactivity, and panic. However, among antipsychotics, the Food and Drug Administration has approved only risperidone and aripiprazole to treat irritability in autism. Among atypical antipsychotics, olanzapine and quetiapine are limited in their use for autism spectrum disorders in children because of high incidences of weight gain and sedation. In comparison, aripiprazole and ziprasidone cause less weight gain and sedation. However, potential QTc interval prolongation with ziprasidone has been reported. Contrary to ziprasidone, no changes were evident in the QT interval in any of the trials for aripiprazole. However, head-to-head comparison studies are needed to support that aripiprazole may be a promising drug that can be used to treat irritability in autistic children. On the other hand, risperidone has the greatest amount of evidence supporting it, including randomized controlled trials; thus, its efficacy and tolerability has been established in comparison with other agents. Further studies with risperidone as a control drug are needed. PMID:24932108

    In fragile X syndrome (FXS), it is hypothesized that absence of the fragile X mental retardation protein (FMRP) disrupts regulation of group 1 metabotropic glutamate receptor (mGluR and mGluR5)-dependent translation in dendrites. Lithium reduces mGluR-activated translation and reverses phenotypes in the dfxr mutant fly and fmr1 knockout mouse. This pilot add-on trial was conducted to evaluate safety and efficacy of lithium in humans with FXS. Fifteen individuals with FXS, ages 6-23, received lithium titrated to levels of 0.8-1.2 mEq/L. The primary outcome measure, the Aberrant Behavior Checklist --Community Edition (ABC-C) Irritability Subscale, secondary outcome measures (other ABC-C subscales, clinical global improvement scale (CGI), visual analog scale for behavior (VAS), Vineland Adaptive Behavior Scale (VABS)), exploratory cognitive and psychophysiological measures and an extracellular signal-regulated kinase (ERK) activation assay were administered at baseline and 2 months of treatment. Side effects were quantified with a standardized checklist and lithium level, complete blood count (CBC), thyroid stimulating hormone (TSH), and chemistry screen were done at baseline, 2 weeks, 4 weeks and 2 months. The only significant treatment-related side effects were polyuria/polydipsia (n = 7) and elevated TSH (n = 4). Although the ABC-C Irritability Subscale showed only a trend toward improvement, there was significant improvement in the Total ABC-C score (p = 0.005), VAS (p = 0.003), CGI (p = 0.002), VABS Maladaptive Behavior Subscale (p = 0.007), and RBANS List Learning (p = 0.03) and an enhanced ERK activation rate (p = 0.007). Several exploratory tasks proved too difficult for lower-functioning FXS subjects. Results from this study are consistent with results in mouse and fly models of FXS, and suggest that lithium is well-tolerated and provides functional benefits in FXS, possibly by modifying the underlying neural defect.

    We investigated the agreement between Japanese parents' and teachers' ratings concerning their children's behavioral/emotional problems. Mothers (n = 276) and teachers (n = 19) assessed each child (n = 316; 6 to 12 years old ) using Japanese parent and teacher version of the Child Behavior Checklist. Parent-teacher agreement were examined through three indices; mean scores, correlations and D scores (generalized distance between item profile). Mean scores rated by parents were significantly higher than those by teachers. The differences of parents' ratings according to sex of the child or parents' occupational level, and those of teachers' ratings according to sex of the child were consistent with previous Western studies. Parent-teacher correlations were in the low to middle range (0.16-0.36). We obtained significant sets of independent variables accounting for the variance of D scores, but the effect size of these variables was small. These results indicated that, as seen in Western studies, Japanese parents and teachers would also assess their child's problems differently and the child's demographics affect their evaluation. For further research, parent and teacher characteristics which may influence on their perspective of the child's problems could be examined.

    Physicians can encounter problems in prescribing opioids for some patients with chronic pain such as multiple unsanctioned dose escalations, episodes of lost or stolen prescriptions, and positive urine drug screenings for illicit substances. This study explored the usefulness of questions on abuse history in predicting problems with prescribing opioids for patients at a hospital-based pain management program. One hundred forty-five (145) patients who were taking long- and short-acting opioids for their pain were classified as high or low risk on the basis of their responses to interview questions about 1) substance abuse history in their family, 2) past problems with drug or alcohol abuse, and 3) history of legal problems. The treating physicians completed a questionnaire about problems that they had encountered with their patients. Problem behaviors were verified through chart review. No differences in demographic characteristics were found between those classified as high and low risk. Patients who admitted to a family history of substance abuse, a history of legal problems, and drug or alcohol abuse were prone to more aberrant drug-related behaviors, including a higher incidence of lost or stolen prescriptions and the presence of illicit substances in their urine (P < 0.05). Patients classified as high risk also had a significantly higher frequency of reported mental health problems and motor vehicle accidents. More of these patients smoked cigarettes, tended to need a cigarette within the first hour of the day, took higher doses of opioids, and reported fewer adverse effects from the medications than did those without such a history (P < 0.05). This study demonstrates that questions about abuse history and legal problems can be useful in predicting aberrant drug-related behavior with opioid use in persons with chronic noncancer pain.

    Autism spectrum disorder (ASD) is a childhood-onset neurodevelopmental disorder with a rapidly rising prevalence, currently affecting 1 in 68 children, and over 3.5 million people in the United States. Current ASD interventions are primarily based on in-person behavioral therapies that are both costly and difficult to access. These interventions aim to address some of the fundamental deficits that clinically characterize ASD, including deficits in social communication, and the presence of stereotypies, and other autism-related behaviors. Current diagnostic and therapeutic approaches seldom rely on quantitative data measures of symptomatology, severity, or condition trajectory. Given the current situation, we report on the Brain Power System (BPS), a digital behavioral aid with quantitative data gathering and reporting features. The BPS includes customized smartglasses, providing targeted personalized coaching experiences through a family of gamified augmented-reality applications utilizing artificial intelligence. These applications provide children and adults with coaching for emotion recognition, face directed gaze, eye contact, and behavioral self-regulation. This preliminary case report, part of a larger set of upcoming research reports, explores the feasibility of the BPS to provide coaching in two boys with clinically diagnosed ASD, aged 8 and 9 years. The coaching intervention was found to be well tolerated and rated as being both engaging and fun. Both males could easily use the system, and no technical problems were noted. During the intervention, caregivers reported improved non-verbal communication, eye contact, and social engagement during the intervention. Both boys demonstrated decreased symptoms of ASD, as measured by the aberrant behavior checklist at 24-h post-intervention. Specifically, both cases demonstrated improvements in irritability, lethargy, stereotypy, hyperactivity/non-compliance, and inappropriate speech. Smartglasses using augmented

    A modified version of the Revised Memory and Behavior Problems Checklist (RMBPC; L. Teri et al., 1992) was administered across 6 different sites to 1,229 family caregivers of community-dwelling adults with dementia. The total sample was divided randomly into 2 subsamples. Principal components analyses on occurrence responses and reaction ratings from the first subsample resulted in a 3-factor solution that closely resembled the originally proposed dimensions (memory-related problems, disruptive behaviors, and depression). Confirmatory factor analyses on data from the second subsample indicated adequate fit for the 3-factor model. Correlations with other caregiver and care-recipient measures supported the convergent and discriminant validity of the RMBPC measures. In addition, female caregivers and White caregivers reported more problems, on average, than male caregivers and African American caregivers, respectively. PMID:14692875

    Detection of external irritants by head nociceptor neurons has deep evolutionary roots. Irritant-induced aversive behavior is a popular pain model in laboratory animals. It is used widely in the formalin-model, where formaldehyde is injected into the rodent paw, eliciting quantifiable nocifensive behavior that has a direct, tissue-injury-evoked phase, and a subsequent tonic phase caused by neural maladaptation. The formalin model has elucidated many anti-pain compounds and pain-modulating signaling pathways. We have adopted this model to trigeminally-innervated territories in mice. Also, we have examined the involvement of TRPV4 channels in formalin-evoked trigeminal pain behavior, because TRPV4 is abundantly expressed in trigeminal ganglion (TG) sensory neurons, also because we have recently defined TRPV4’s role in response to air-borne irritants, and in a model for temporomandibular joint pain. We found TRPV4 to be important for trigeminal nocifensive behavior evoked by formalin whiskerpad injections. This conclusion is supported by studies with Trpv4−/− mice and TRPV4-specific antagonists. Our results imply TRPV4 in MEK-ERK activation in TG sensory neurons. Furthermore, cellular studies in primary TG neurons and in heterologous TRPV4-expressing cells suggest that TRPV4 can be activated directly by formalin to gate Ca++. Using TRPA1-blocker and Trpa1−/− mice, we found that both TRP channels co-contribute to the formalin trigeminal pain response. These results imply TRPV4 as an important signaling molecule in irritation-evoked trigeminal pain. TRPV4-antagonistic therapies can therefore be envisioned as novel analgesics, possibly for specific targeting of trigeminal pain disorders, such as migraine, headaches, TMJ, facial and dental pain, and irritation of trigeminally-innervated surface epithelia.

    Road accidents are a social phenomenon in different communities that its infra-structural dimensions of which as well as technologic failures such as road quality, and tech-nical faults of automobiles, need to be assessed in detail. Iran has the first order in the world for deadly road accidents. This study was designed to assess the association between aberrant behaviors of truck drivers and the incidence of road accidents in Yazd, center of Iran, in 2010. This cross-sectional descriptive-analytic study was conducted on 300 truck drivers in Yazd. We used 3 questionnaires, including one for demographic data, Driver Behavior Questionnaire (DBQ), and one for drivers' self-evaluation of the of their driving. Five types of the behavior had the highest frequency: Misjudge speed of oncoming vehicle when overtaking.; Deliberately disregard the speed limits late at night or very early in the morning.; Ignore 'give way' signs, and narrowly avoid colliding with traffic having right of way.; Stuck behind a slow-moving vehicle on a two-lane highway, you are driven by frustration to try to overtake in risky circumstances.; Drive with only 'half-an-eye' on the road while looking at a map, changing a cassette or radio channel, etc. The more the driver's driv-ing was influenced by emotional and mental states the more deliberate violations and slips. Among truck drivers, safety has not developed sufficiently, and because of the dangers of road accidents both for the drivers and other people and its economic losses, the importance of the presenting some solutions is completely obvious.

    The aims of this study were (1) to assess obsessive-compulsive symptoms (OCS) dimensionally in a school-aged community sample and to correlate them with clinical and demographical variables; (2) to determine a subgroup with significant OCS ("at-risk for OCD") using the Child Behavior Checklist (CBCL-OCS) and (3) to compare it with the rest of the sample; (4) To review the CBCL-OCS subscale properties as a screening tool for pediatric OCD. Data from the Brazilian High Risk Cohort were analyzed. The presence and severity of OCS were assessed through the CBCL-OCS subscale. DSM-IV psychiatric diagnoses were obtained by the Developmental and Well-Being Assessment. Behavioral problems were assessed using the Strengths and Difficulties Questionnaire, the Youth Strengths Inventory, and the CBCL internalizing and externalizing behavior subscales. A total of 2512 (mean age: 8.86 ± 1.84 years; 55.0% male) children were included. Moderate correlations were found between OCS severity and functional impairment (r = 0.36, p < 0.001). Children with higher levels of OCS had higher rates of psychiatric comorbidity and behavioral problems (p < 0.001). A score of 5 or higher in the CBCL-OCS scale determined an "at-risk for OCD" subgroup, comprising 9.7% of the sample (n = 244), with behavioral patterns and psychiatric comorbidities (e.g., tics [odds ratios, OR = 6.41, p < 0.001]), anxiety disorders grouped [OR = 3.68, p < 0.001] and depressive disorders [OR = 3.0, p < 0.001] very similar to those described in OCD. Sensitivity, specificity, positive predictive value, and negative predictive value of the CBCL-OCS for OCD diagnosis were, respectively, 48%, 91.5%; 15.1%, and 98.2%. The dimensional approach suggests that the presence of OCS in children is associated with higher rates of comorbidity, behavioral problems, and impairment. The "at-risk for OCD" group defined by the CBCL revealed a group of patients phenotypically similar to full

    Irritable mood is common in children with attention-deficit/hyperactivity disorder. Research to date has primarily comprised cross-sectional studies; thus, little is known about the antecedents of irritability. Furthermore, existing cross-sectional studies generally focus on the association between irritability and comorbidities and do not examine broader aspects of functioning. Finally, previous research has neglected to include child-report of irritability. This study aimed to address these gaps using data from a longitudinal study of children with attention-deficit/hyperactivity disorder. Children aged 5-13 years (mean = 10.2; standard deviation = 1.9) with attention-deficit/hyperactivity disorder were recruited from pediatric practices across Victoria, Australia. This study reports on those who had reached adolescence (12 years or older, mean = 13.8; standard deviation = 1.2) at the 3-year follow-up ( n = 140). Internalizing and externalizing problems were measured using the Strengths and Difficulties Questionnaire. At follow-up, parent-reported and adolescent self-reported irritability was assessed using the Affective Reactivity Index. Parent and adolescent outcomes measured at follow-up included attention-deficit/hyperactivity disorder symptom severity, sleep, behavior and parent mental health. Children with externalizing problems at age 10 had higher parent-reported irritability (β = 0.31, 95% confidence interval = [0.17,-0.45], p = 0.001) in adolescence. Cross-sectional analyses found that irritability was associated with increased attention-deficit/hyperactivity disorder symptom severity and sleep problems; poorer emotional, behavioral and social functioning; and poorer parent mental health. Our findings highlight the importance of assessing for and managing early conduct problems in children with attention-deficit/hyperactivity disorder, as these predict ongoing irritability which, in turn, is associated with poorer

    Individuals with a history of traumatic brain injury (TBI) may have chronic problems with irritability, which can negatively affect their lives. (1) To describe the experience (thoughts and feelings) of irritability from the perspectives of multiple people living with or affected by the problem, and (2) to develop a conceptual model of irritability. Qualitative, participatory research. Forty-four stakeholders (individuals with a history of TBI, family members, community professionals, healthcare providers, and researchers) divided into 5 focus groups. Each group met 10 times to discuss the experience of irritability following TBI. Data were coded using grounded theory to develop themes, metacodes, and theories. Not applicable. A conceptual model emerged in which irritability has 5 dimensions: affective (related to moods and feelings); behavioral (especially in areas of self-regulation, impulse control, and time management); cognitive-perceptual (self-talk and ways of seeing the world); relational issues (interpersonal and family dynamics); and environmental (including environmental stimuli, change, disruptions in routine, and cultural expectations). This multidimensional model provides a framework for assessment, treatment, and future research aimed at better understanding irritability, as well as the development of assessment tools and treatment interventions.

    Communication contributes to increased stress, mortality, and decreased quality of life (QOL) for persons with dementia (PWD) and caregivers. PWD use communicative coping behaviors (CCBs) to manage the demands of the disease. However, most assessments neither look for nor give credit to communication behaviors. This is the first study to examine CCBs in the home environment as measured by the Communicative Coping Behavior Checklist (CCBC). This cross-sectional quantitative study included 26 dementia and 18 cognitively normal control dyads. Raters observed their partners' CCBs at home, over several weeks and completed the CCBC. We analyzed the endorsement rates (how often behaviors were observed by a rater) of emotion and activity-focused CCBs in dementia and control dyads. The primary outcome was rate of CCB endorsement. Secondary outcomes included dementia diagnosis, cognitive status, depressive mood, life satisfaction (SWL) and QOL. Dementia dyads endorsed 11 of 23 CCBs significantly more than control dyads. Action-focused CCBs (p < .001) were more frequent than emotion-focused CCBs (p = .004) in dementia dyads. Specific CCBs such as humor correlated with higher caregiver QOL (p = .019) and PWD's SWL (p = .003). Another CCB, general humor, correlated with lower PWD's SWL (p = .024). This was the first study to examine CCBs in the home environment comparing dementia and control dyads. Higher endorsement rates of action-focused than emotion-focused CCBs were seen in dementia dyads. We conclude that attention to CCBs during treatment and care will improve QOL and SWL of PWD and caregivers. © The Author 2016.

    Irritable bowel syndrome (IBS) is a highly prevalent disorder with a significant impact on quality of life. The presence of psychological symptoms in IBS patients such as catastrophic worry and behavioral avoidance suggests the possible efficacy of cognitive behavioral interventions. Exposure-based cognitive behavioral therapy (CBT) has proven to be a promising approach but has only been investigated in a few studies and mainly via the Internet. Therefore, the aims of this study were to extend and replicate previous findings and to evaluate whether an individual, face-to-face, exposure-based CBT leads to improvement in gastrointestinal symptoms, pain catastrophizing, avoidance behavior and quality of life in IBS patients. Thirteen patients with IBS according to Rome III criteria participated in a single-case experimental study using a five-week baseline and a subsequent twelve-session intervention phase focusing on psycho-education, mindfulness and in vivo exposure. Standardized measurement of gastrointestinal symptoms, pain catastrophizing, avoidance behavior and quality of life was conducted weekly during baseline as well as intervention phase and at six-month follow-up. Results showed that over 70% of patients improved significantly on gastrointestinal symptoms, pain catastrophizing, and quality of life. Effects on avoidance behavior were modest. These results strengthen and extend earlier findings and provide further support for the efficacy of exposure-based strategies for IBS.

    Autism is associated with activation of the inflammatory response system. This study aims to assess the efficacy of a cyclooxygenase-2 inhibitor, celecoxib, as adjunctive therapy in the treatment of autism In a 10-week randomized double-blind placebo-controlled study, 40 outpatient children with a Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision clinical diagnosis of autism were randomly allocated to celecoxib plus risperidone or placebo plus risperidone. The dose of risperidone and celecoxib were titrated up to 3 and 300 mg/day, respectively. Patients were assessed at baseline and after 2, 4, 6, and 10 weeks of starting medication using the Aberrant Behavior Checklist-Community (ABC-C) Rating Scale. Primary outcome measure was the change in irritability subscale of ABC-C. Significant time × treatment interaction was observed for Irritability (F (1.658, 63.021) = 13.580, P < 0.001), Lethargy/Social Withdrawal (F (1.948, 74.032) = 16.811, P < 0.001), and Stereotypic Behavior (F(1.742, 66.198) = 12.104, P < 0.001), but not for Hyperactivity/Noncompliance (F (2.564, 97.424) = 1.469, P = 0.232), and Inappropriate Speech subscales (F (1.607, 61.075) = 0.173, P = 0.794). By week 10, patients in the celecoxib group showed significantly greater improvement in the Irritability (P < 0.001), Lethargy/Social Withdrawal (P < 0.001), and Stereotypic Behavior (P < 0.00) but not in Hyperactivity/Noncompliance (P = 0.202) and Inappropriate Speech (P = 0.802) subscales than the placebo group. Complete response was achieved by four (20 %) patients in the placebo group and 11 (55 %) patients in the celecoxib group (χ (2) (1) = 5.227, P = 0.022). Frequency of side effects was similar between the two groups. Combination of risperidone and celecoxib was superior to risperidone alone in treating irritability, social withdrawal, and stereotypy of children with autism. (Registration

    To determine the course of neuropsychiatric symptoms (NPSs) in nursing home residents with dementia and to determine their variability across diagnosis. Prospective cohort study over 2 years. Fourteen dementia special care units in nine nursing homes in The Netherlands. One hundred seventeen residents with dementia. NPSs were measured using the Neuropsychiatric Inventory-Nursing Home version (NPI-NH). The majority of residents had moderately severe to severe dementia. All but a few residents (97%) showed any NPS, and co-occurrence of NPSs was high. Agitation, irritability, and aberrant motor behavior were the most prevalent over the 2 years. Depression and anxiety as well as NPI total score decreased over time, whereas apathy tended to increase. Agitation and aberrant motor behavior were the most persistent symptoms. In asymptomatic residents, highest incidence rates were found for apathy, aggression/ agitation, irritability, and aberrant motor behavior. Anxiety and apathy were more prevalent in Alzheimer disease (AD) compared with vascular disease (VaD); vice versa, aggression and depression were more prevalent in VaD. Differences in change over time between AD and VaD were found for irritability and disinhibition. This is the first study examining the 2-year course of NPSs in a large group of nursing home residents with dementia. Virtually all residents demonstrated and/or developed NPSs. Although affective symptoms decreased, apathy tended to increase. Agitated behaviors were particularly persistent. Our data may contribute to improve mental healthcare for demented nursing home residents.

    Self-injurious behavior (SIB) and stereotyped behavior (SB) are major challenges for professionals in the field of mental retardation. From animal experiments it has become obvious that these behavioral disturbances are not purposeless but may emerge secondary to restrictive environment and may serve de-arousing objectives. In mentally retarded subjects, several hypotheses have been formulated concerning the pathogenesis of SIB, particularly about the involvement of serotonin and beta-endorphin, which are supported by beneficial treatment effects of the opiate antagonist naltrexone and serotonin modulating compounds, respectively. The present study was designed to investigate basal levels of stress-hormonal and serotonergic parameters as well as plasma levels of amino-acids and the beta-carboline norharman in a group of 64 mentally retarded subjects with SB and/or SIB. Allocation to three different groups comprising 17 retarded controls, 26 subjects with mainly SIB and 21 subjects with mainly SB, was originally performed using the scores on the factors Irritability, Stereotypic Behaviour and Hyperactivity of the Aberrant Behavioral Checklist. Because of the overlapping nature of the behavioral parameters, subjects were subsequently divided into three maximally contrasting groups, viz. predominantly SIB, predominantly SB and retarded controls, each comprising 11 subjects. With respect to beta-endorphin, no differences were found either between both the original and maximally contrasting groups or in comparison to nonretarded controls. As compared to retarded controls, a tendency to lower values for total cortisol and cortisol binding globulin appeared to be present in the SIB group, whereas in the SB group a tendency toward higher levels of the major serotonin metabolite 5-HIAA was found. In the contrasting SB group, a trend toward decreased total cortisol level was observed as compared to the retarded control group. In addition, significantly lower values for

    To develop and provide validity evidence for a performance checklist to evaluate the child abuse screening behaviors of prehospital providers. Checklist Development: We developed the first iteration of the checklist after review of the relevant literature and on the basis of the authors' clinical experience. Next, a panel of six content experts participated in three rounds of Delphi review to reach consensus on the final checklist items. Checklist Validation: Twenty-eight emergency medical services (EMS) providers (16 EMT-Basics, 12 EMT-Paramedics) participated in a standardized simulated case of physical child abuse to an infant followed by one-on-one semi-structured qualitative interviews. Three reviewers scored the videotaped performance using the final checklist. Light's kappa and Cronbach's alpha were calculated to assess inter-rater reliability (IRR) and internal consistency, respectively. The correlation of successful child abuse screening with checklist task completion and with participant characteristics were compared using Pearson's chi squared test to gather evidence for construct validity. The Delphi review process resulted in a final checklist that included 24 items classified with trichotomous scoring (done, not done, or not applicable). The overall IRR of the three raters was 0.70 using Light's kappa, indicating substantial agreement. Internal consistency of the checklist was low, with an overall Cronbach's alpha of 0.61. Of 28 participants, only 14 (50%) successfully screened for child abuse in simulation. Participants who successfully screened for child abuse did not differ significantly from those who failed to screen in terms of training level, past experience with child abuse reporting, or self-reported confidence in detecting child abuse (all p > 0.30). Of all 24 tasks, only the task of exposing the infant significantly correlated with successful detection of child abuse (p < 0.05). We developed a child abuse checklist that demonstrated strong

Latest research indicates that the brain-gut axis plays a key role in the disorder, and the presence of psychological factors and central processing deficits contribute to symptom severity and disability. Psychological therapies as a whole have demonstrated good efficacy in reducing the severity of IBS symptoms. Cognitive-behavioral therapy (CBT) has been tested most rigorously in multiple randomized controlled trials and consistently demonstrates significant and durable effects on IBS symptoms and quality of life. Various protocols for treating IBS have been developed, and most recent advances in the field include exposure-based treatments to target symptom-specific anxiety as well as modified delivery methods, including internet-based treatment models. Despite the well-documented advantages of CBT for IBS, it has been poorly disseminated and few patients have access to this treatment. The primary barrier to dissemination is the limited number of therapists with adequate training in GI psychology to provide this evidence-based intervention. Future developments in the field need to focus on training opportunities to equip more therapists to competently provide CBT for this population. Further efforts to develop telemedicine platforms for delivering this intervention will also improve accessibility for patients.

    Efficacy and safety of 2 risperidone doses were evaluated in children and adolescents with autism. Patients (N = 96; 5-17 years), received risperidone (low-dose: 0.125 mg/day [20 to <45 kg], 0.175 mg/day [>45 kg] or high-dose: 1.25 mg/day [20 to <45 kg], 1.75 mg/day [>45 kg]) or placebo. Mean baseline (range 27-29) to endpoint change in Aberrant Behavior Checklist-Irritability (primary endpoint) was significantly greater in the high-dose-(-12.4 [6.5]; p < 0.001), but not low-dose (-7.4 [8.1]; p = 0.164) group, versus placebo (-3.5 [10.7]). Clinical Global Impressions-Severity and Children's Yale-Brown Obsessive Compulsive Scale scores improved significantly only in the high-dose group, consistent with ABC-I results. Somnolence, sedation and increased appetite occurred more frequently in high-versus low-dose groups. Overall, increased appetite occurred most frequently.

    The use of complementary and alternative medicine by children with autism and the association of its use with child comorbid symptoms and parental stress was studied in an ethnically diverse population, in a cross-sectional study with structured interviews. The sample included 50 families of children with autism and 50 families of children with other developmental disabilities, matched by age/gender. Interview included the Complementary and Alternative Medicine Questionnaire, Gastrointestinal Questionnaire, Children's Sleep Habits Questionnaire, Aberrant Behavior Checklist, and Parenting Stress Index. In this ethnically diverse sample, the use of complementary and alternative medicine was significantly higher for the autism group. In the autism group, use was significantly related to child's irritability, hyperactivity, food allergies, and parental stress; in the developmental disabilities group, there was no association with child comorbid symptoms or parental stress. The results contribute information to health care providers about families of children with autism who are more likely to use complementary and alternative medicine.

    Autistic disorder is a largely misunderstood and difficult to treat neurodevelopmental disorder. Three core domains of functioning are affected by autistic disorder, ie, socialization, communication, and behavior. Signs of autistic disorder may be present early, but are frequently overlooked, resulting in a delay in its diagnosis and a subsequent delay in treatment. No one definitive therapy is available, and treatment consists of early educational and behavioral interventions, as well as drug therapy. Atypical antipsychotics have often been used in the treatment of autistic disorder to target irritability, aggression, and self-injurious behavior, all of which can interfere with other aspects of treatment. One atypical antipsychotic, aripiprazole, has recently been approved for treatment of irritability associated with autistic disorder. Based on the results from two randomized, controlled trials, with efficacy data from nearly 300 patients, treatment with aripiprazole was associated with reductions in irritability, global improvements in behavior, and improvements in quality of life from both the patient and caregiver perspectives. Dosage of aripiprazole ranged from 5 mg to 15 mg per day. Aripiprazole was well tolerated during clinical trials, with most adverse events considered mild or moderate. Clinically relevant weight gain occurred in about 30% of patients given aripiprazole, although when compared with other atypical antipsychotics, aripiprazole appears to have fewer metabolic effects and a lower risk of weight gain. However, pediatric patients taking any atypical antipsychotic should be carefully monitored for potential adverse events, because the long-term effects of antipsychotic therapy in this population are not well known. When used appropriately, aripiprazole has the potential to be an effective treatment for children with autistic disorder to improve irritability and aggressive behavior and improve quality of life.

  16. Taxanes: vesicants, irritants, or just irritating?

    Several classes of antineoplastic agents are universally referred to as vesicants with ample supporting literature. However, the literature surrounding the taxanes is controversial. While the American Society of Clinical Oncology and Oncology Nursing Society Chemotherapy Administration Safety Standards and the Chemotherapy and Biotherapy Guidelines and Recommendations for Practice identify the risks of extravasation and the parameters surrounding the infusion of known vesicants, recommend administration sites for known agents, and recommend antidotes for particular extravasation cases, they fail to provide specific recommendations for the administration of individual taxanes, or a classification system for antineoplastic agents as vesicants, irritants, or inert compounds. There is also a lack of prescribing information regarding such recommendations. The lack of a formal classification system further complicates the accurate delineation of vesicant antineoplastic agents and subsequent appropriate intravenous administration and extravasation management. There are several factors that make the classification of taxanes as vesicants or irritants challenging. Comprehensive preclinical data describing potential mechanisms of tissue damage or vesicant-like properties are lacking. Furthermore, most case reports of taxane extravasation fail to include the parameters surrounding administration, such as the concentration of medication and duration of infusion, making it difficult to set parameters for vesicant potential. Subsequently, many practitioners default to central venous administration of taxanes without evidence that such administration minimizes the risk of extravasation or improves outcomes thereof. Here, we review briefly the data surrounding taxane extravasation and potential vesicant or irritant properties, classify the taxanes, and propose a spectrum for antineoplastic agent potential to cause tissue injury that warrants clinical intervention if extravasation

    Background An instrument should have been developed to measure participation as one possible criterion to evaluate inclusion of elderly people with intellectual disability. The ICF was utilized, because participation is one part of health related functioning, respectively disability. Furthermore ICF includes environmental factors (contextual factors) and attaches them an essentially influence on health related functioning, in particular on participation. Thus ICF Checklist additionally identifies environmental barriers for elimination. Methodology A linking process with VINELAND-II yielded 138 ICF items for the Checklist. The sample consists of 50 persons with a light or moderate intellectual disability. Two-thirds are female and the average age is 68. They were directly asked about their perceived quality of life. Additionally, proxy interviews were carried out with responsible staff members concerning necessary support and behavioral deviances. The ICF Checklist was administered twice, once (t2) the current staff member should rate health related functioning at the given time and in addition, a staff member who knows the person at least 10 years before (t1) should rate the former functioning. Content validity was investigated with factor analysis and criterion validity with correlational analysis related to supports need, behavioral deviances and perceived quality of life. Quantitative analysis was validated by qualitative content analysis of patient documentation. Results Factor analysis shows logical variable clusters across the extracted factors but neither interpretable factors. The Checklist is reliable, valid related to the chosen criterions and shows the expected age-related shifts. Qualitative analysis corresponds with quantitative data. Consequences/Conclusion ICF Checklist is appropriate to manage and evaluate patient-centered care. © Georg Thieme Verlag KG Stuttgart · New York.

    The implementation of interdisciplinary teams in the intensive care unit (ICU) has focused attention on leadership behavior. A daily recurrent situation in ICUs in which both leadership behavior and interdisciplinary teamwork are integrated concerns the interdisciplinary rounds (IDRs). Although IDRs are recommended to provide optimal interdisciplinary and patient-centered care, there are no checklists available for leading physicians. We tested the measurement properties and implementation of a checklist to assess the quality of leadership skills in interdisciplinary rounds. The measurement properties of the checklist, which included 10 essential quality indicators, were tested for interrater reliability and internal consistency and by factor analysis. The interrater reliability among 3 raters was good (κ, 0.85) and the internal consistency was acceptable (α, 0.74). Factor analysis showed all factor loadings on 1 domain (>0.65). The checklist was further implemented during videotaped IDRs which were led by senior physicians and in which 99 patients were discussed. Implementation of the checklist showed a wide range of "no" and "yes" scores among the senior physicians. These results may underline the need for such a checklist to ensure tasks are synchronized within the team.

    This report describes a design checklist targeted to fault-tolerant distributed electronic systems. Many of the questions and discussions in this checklist may be generally applicable to the development of any safety-critical system. However, the primary focus of this report covers the issues relating to distributed electronic system design. The questions that comprise this design checklist were created with the intent to stimulate system designers' thought processes in a way that hopefully helps them to establish a broader perspective from which they can assess the system's dependability and fault-tolerance mechanisms. While best effort was expended to make this checklist as comprehensive as possible, it is not (and cannot be) complete. Instead, we expect that this list of questions and the associated rationale for the questions will continue to evolve as lessons are learned and further knowledge is established. In this regard, it is our intent to post the questions of this checklist on a suitable public web-forum, such as the NASA DASHLink AFCS repository. From there, we hope that it can be updated, extended, and maintained after our initial research has been completed.

    This study assesses and compares prevalence of psychological and behavioral symptoms in a Belgian sample of people with and without dementia. A total of 228 persons older than 65 years with dementia and a group of 64 non-demented persons were assessed using the Neuropsychiatric Inventory (NPI) in 2004. Within the group without dementia, the most frequent symptoms were depression, agitation, and irritability. Within the group with dementia, the most common symptoms were depression, irritability, apathy, and agitation. Prevalence of delusions (P < 0.05), hallucinations (P < 0.05), anxiety (P < 0.05), agitation (P < 0.05), apathy (P < 0.01), aberrant motor behavior (P < 0.01), and eating disorders (P < 0.05) were significantly higher in the group with dementia. Depression, elation, irritability, disinhibition, and sleeping disorders are not specific to dementia. Agitation, apathy, anxiety, and delusions are more frequent in dementia but were not specific to the dementia group because their prevalence rates were close to 10% in the group without dementia. Hallucinations, aberrant motor behavior, and eating disorders are specific to dementia. The distinction between specific and nonspecific symptoms may be useful for etiological research on biological, psychological, and environmental factors.

    Objective Most research on irritability and child psychopathology has focused on depressive disorders, bipolar disorder, and/or oppositional defiant disorder (ODD). Less is known about relationships between child anxiety and irritability and moderators of such associations. Method Structural equation modeling (SEM) examined associations between anxiety severity and irritability in a large sample of treatment-seeking youth with anxiety disorders (N=663, ages 7–19 years, M=12.25), after accounting for comorbid depressive disorders and ODD. Additional analyses examined whether associations were moderated by child gender, age, and generalized anxiety disorder (GAD) status. Results There was a direct link between child anxiety and irritability even after accounting for comorbid depressive disorders and ODD. Links between child anxiety and irritability were robust across child gender and age. Further, relationships between child anxiety and irritability were comparable across youth with and without GAD, suggesting that the anxiety–irritability link is relevant across child anxiety disorders and not circumscribed to youth with GAD. Conclusion Findings add to an increasing body of evidence linking child irritability to a range of internalizing and externalizing psychopathologies, and suggest that child anxiety assessment should systematically incorporate irritability evaluations. Further, youth in clinical settings displaying irritability should be assessed for the presence of anxiety. Moreover, treatments for childhood anxiety may do well to incorporate new treatment modules as needed that specifically target problems of irritability. PMID:26703910

    This study measured gender differences in Prader-Willi syndrome (PWS) in regard to the severity of behavioral symptoms. The Food Related Problem Questionnaire (FRPQ), the Aberrant Behavior Checklist Japanese Version, the Childhood Routines Inventory, the Pervasive Developmental Disorders Autism Society Japan Rating Scale, and Japanese ADHD-RS were administered to PWS patients (45 males aged 6 to 58 and 37 females aged 6 to 45). To examine the effects that gender and genotype have on the severity of each symptom, two-way ANOVAs were conducted. Significant interactions were found only in regard to FRPQ scores, such as FRPQ total score (F(1, 78) = 8.43, p < 0.01). The FRPQ of male deletion (DEL) individuals was higher than that of female DEL and male mUPD. The FRPQ of male maternal uniparental disomy (mUPD) was lower than that of female mUPD. In terms of problem behaviors, routines, autistic behaviors, and hyperactivity, no significant differences were found. Food-related behaviors in DEL were more severe in males, although those in mUPD were less severe in males.

    To test the hypothesis that amantadine hydrochloride is a safe and effective treatment for behavioral disturbances--for example, hyperactivity and irritability--in children with autism. Thirty-nine subjects (intent to treat; 5-19 years old; IQ > 35) had autism diagnosed according to DSM-IV and ICD-10 criteria using the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule-Generic. The Aberrant Behavior Checklist-Community Version (ABC-CV) and Clinical Global Impressions (CGI) scale were used as outcome variables. After a 1-week, single-blind placebo run-in, patients received a single daily dose of amantadine (2.5 mg/kg per day) or placebo for the next week, and then bid dosing (5.0 mg/kg per day) for the subsequent 3 weeks. When assessed on the basis of parent-rated ABC-CV ratings of irritability and hyperactivity, the mean placebo response rate was 37% versus amantadine at 47% (not significant). However, in the amantadine-treated group there were statistically significant improvements in absolute changes in clinician-rated ABC-CVs for hyperactivity (amantadine -6.4 versus placebo -2.1; p = .046) and inappropriate speech (-1.9 versus 0.4; p = .008). CGI scale ratings were higher in the amantadine group: 53% improved versus 25% (p = .076). Amantadine was well tolerated. Parents did not report statistically significant behavioral change with amantadine. However, clinician-rated improvements in behavioral ratings following treatment with amantadine suggest that further studies with this or other drugs acting on the glutamatergic system are warranted. The design of these and similar drug trials in children with autistic disorder must take into account the possibility of a large placebo response.

    Abstract Given the numerous threats against Earth’s coral reefs, there is an urgent need to develop means of assessing reef coral health on a proactive timescale. Molecular biomarkers may prove useful in this endeavor because their expression should theoretically undergo changes prior to visible signs of health decline, such as the breakdown of the coral-dinoflagellate (genus Symbiodinium) endosymbiosis. Herein 13 molecular- and physiological-scale biomarkers spanning both eukaryotic compartments of the anthozoan-Symbiodinium mutualism were assessed across 70 pocilloporid coral colonies sampled from reefs of Fiji’s easternmost province, Lau. Eleven colonies were identified as outliers upon employment of a detection method based partially on the Mahalanobis distance; these corals were hypothesized to have been displaying aberrant sub-cellular behavior with respect to their gene expression signatures, as they were characterized not only by lower Symbiodinium densities, but also by higher levels of expression of several stress-targeted genes. Although these findings could suggest that the sampled colonies were physiologically compromised at the time of sampling, further studies are warranted to state conclusively whether these 11 scleractinian coral colonies are more stress-prone than nearby conspecifics that demonstrated statistically normal phenotypes.

    A decrease in respiratory rate in mice during exposure to irritating airborne chemicals has been utilized as a response parameter to characterize the degree of upper respiratory tract irritation (sensory irritation) to the thermal decomposition products of various polymers. These included polystyrene, polyvinyl chloride, flexible polyurethane foam, polytetrafluorethylene, a fiber glass reinforced polyester resin, and Douglas Fir. Each of the materials was thermally decomposed in a low-mass vertical furnace in an air atmosphere at a programmed heating rate of 20 degrees C/min. Mice, in groups of four, were exposed to graded concentrations of the thermal decomposition products of each of the above materials. Dose-response curves were obtained by utilizing the maximum percent decrease in respiratory rate as the response parameter during each exposure. Comparison of these dose-response curves with other sensory irritants such as chlorine, ammonia, hydrogen chloride, sulfur dioxide, and toluene diisocyanate gave an indication of the sensory irrtation potential of the thermal decomposition products of these various polymers versus that of well-known single airborne chemical irritants. Total stress and incapacitation of the organism during exposure to sensory irritants such as from the thermal decomposition products of synthetic polymers is discussed.

    Irritability and the new DSM-5 diagnostic category of Disruptive Mood Dysregulation Disorder (DMDD) have been conceptualised as related to mood disorder. Irritability is common in Attention Deficit Hyperactivity Disorder (ADHD) but little is known about its association with depression risk in this group. This study aims to establish levels of irritability and prevalence of DMDD in a clinical sample of children with ADHD, and examine their association with anxiety, depression and family history of depression. The sample consisted of 696 children (mean age 10.9 years) with a diagnosis of ADHD, recruited from UK child psychiatry and paediatric clinics. Parents completed the Child and Adolescent Psychiatric Assessment, a semi-structured diagnostic interview, about their child. This was used to establish prevalence of DMDD, anxiety disorder and depressive disorder, as well as obtain symptom scores for irritability, anxiety and depression. Questionnaires assessed current parental depression, and family history of depression. Irritability was common, with 91% endorsing at least one irritable symptom. 3-month DMDD prevalence was 31%. Children with higher levels of irritability or DMDD were more likely to have comorbid symptoms of anxiety, depression and a family history of depression. Results are based on a clinical sample, so may not be generalizable to children with ADHD in the general population. Irritability and DMDD were common, and were associated with markers of depression liability. Longitudinal studies are needed to examine the association between irritability and depression in youth with ADHD as they get older. Copyright © 2017. Published by Elsevier B.V.

    The current goal of treatment in irritable bowel syndrome (IBS) focuses primarily on symptom management and attempts to improve quality of life. Several treatments are at the disposal of physicians; lifestyle and dietary management, pharmacological treatments and psychological interventions are the most used and recommended. Psychological treatments have been proposed as viable alternatives or compliments to existing care models. Most forms of psychological therapies studied have been shown to be helpful in reducing symptoms and in improving the psychological component of anxiety/depression and health-related quality of life. According to current NICE/NHS guidelines, physicians should consider referral for psychological treatment in patients who do not respond to pharmacotherapy for a period of 12 months and develop a continuing symptom profile (described as refractory irritable bowel syndrome). Cognitive behavioral therapy (CBT) is the best studied treatment and seems to be the most promising therapeutic approach. However, some studies have challenged the effectiveness of this therapy for irritable bowel syndrome. One study concluded that cognitive behavioral therapy is no more effective than placebo attention control condition and another study showed that the beneficial effects wane after six months of follow-up. A review of mind/body approaches to irritable bowel syndrome has therefore suggested that alternate strategies targeting mechanisms other than thought content change might be helpful, specifically mindfulness and acceptance-based approaches. In this article we review these new psychological treatment approaches in an attempt to raise awareness of alternative treatments to gastroenterologists that treat this clinical syndrome.

    Irritable bowel syndrome is a complex disorder whose pathophysiology involves alterations in the enteric microbiota, visceral hypersensitivity, gut immune/barrier function, hypothalamic-pituitary-adrenal axis regulation, neurotransmitters, stress response, psychological factors, and more. The importance of diet in the management of irritable bowel syndrome has taken center stage in recent times as the literature validates the relationship of certain foods with the provocation of symptoms. Likewise, a number of elimination dietary programs have been successful in alleviating irritable bowel syndrome symptoms. Knowledge of the dietary management strategies for irritable bowel syndrome will help guide nutritionists and healthcare practitioners to deliver optimal outcomes.

    To describe the recent insights into the definition, causes, natural outcome, and key elements of irritant-induced asthma (IIA) management. IIA is a subtype of occupational asthma without immunologic sensitization and includes the typical reactive airway dysfunction syndrome (RADS) and a more gradual form called not-so-sudden IIA, when onset of asthma follows repeated low-dose exposure to irritants. The World Trade Center tragedy brought new insight in the understanding of IIA, suggesting that it can exhibit a prolonged interval between exposure and recognition of clinical symptoms and disease. Dimethyl sulfate has been recently reported to cause RADS and repeated diesel exhaust exposure to cause not-so-sudden IIA in patients who worked in a bus garage. Cleaning workers who are exposed to a large variety of irritants and sensitizers are especially at risk of occupational asthma and IIA. IIA includes RADS and not-so-sudden IIA. Outcome of IIA is as poor as occupational asthma with sensitization. Treatment of IIA does not differ from standard asthma treatment, but high-dose vitamin D could be assessed further for possible therapeutic benefit.

    Background Research on susceptibility to alcohol use disorder within the Attention-Deficit/Hyperactivity Disorder (ADHD) population has begun to expand examination of putative moderators and mediators in order to develop effective treatments. Specific dysregulated emotions have been separately associated with ADHD and with alcohol use difficulties. The current study is the first to conjointly study these variables by testing anger-irritability as a mediator of ADHD risk for adolescent alcohol use. Methods Frequency of binge drinking, drunkenness, and alcohol problems were examined for 142 children with ADHD followed into adolescence and compared to 100 demographically similar youth without ADHD. Parent-rated anger-irritability was tested as a mediator. Behavioral and cognitive coping skills, which are key clinical treatment targets, were studied as moderators of these associations. Results Childhood ADHD was positively associated with anger-irritability and the drinking outcomes in adolescence. Anger-irritability mediated the association between ADHD and alcohol use problems, but not binge drinking or drunkenness. Behavioral and cognitive, but not avoidant, coping played a moderating role, but only of the association between childhood ADHD and anger-irritability. Conclusions Active coping strategies by adolescents with ADHD may reduce the vulnerability to alcohol problems through a reduction of negative emotions. Future research on additional mediators and treatments that target these skills is encouraged. PMID:27991655

    We aimed to evaluate the Child Behavior Checklist (CBCL) profiles in youths with bipolar and depressive disorders. Seventy-four subjects with a mean age of 14.9±1.6years (36 boys) with mood disorders and their parents were recruited from September 2011 to June 2013 in the Department of Psychiatry, Asan Medical Center, Seoul, Korea. Diagnosis of mood disorder and comorbid psychiatric disorder was confirmed by child psychiatrists using the Schedule for Affective Disorders and Schizophrenia for School Age Children - Present and Lifetime version (K-SADS-PL). The parents of the subjects completed the Parent General Behavior Inventory-10-item Mania Scale (P-GBI-10M), Parent-version of Mood Disorder Questionnaire (P-MDQ), ADHD rating scale (ARS) and CBCL. The adolescents completed the 76-item Adolescent General Behavior Inventory (A-GBI), Beck Depression Inventory (BDI), and Adolescent-version of Mood Disorder Questionnaire (A-MDQ). When adjusted for gender and the comorbidity with ADHD, the Withdrawn and Anxious/Depressed subscale scores of the CBCL were higher in subjects with bipolar disorder than in those with depressive disorder. Higher scores of A-GBI Depressive subscale, A-MDQ and BDI were shown in subjects with bipolar disorder than in those with depressive disorder. There was no significant difference on CBCL-DP, P-GBI-10M, P-MDQ, A-GBI Hypomanic/Biphasic subscale and ARS between two groups. All eight subscales of the CBCL positively correlated with the P-GBI-10M and P-MDQ scores, and seven of all eight subscales of the CBCL positively correlated with A-GBI Depressive and Hypomanic/Biphasic subscales. The BDI score was positively associated with the Withdrawn, Somatic Complaints, Anxious/Depressed, and Social Problems subscale scores. CBCL-DP score was strongly correlated with manic/hypomanic symptoms measured by P-GBI-10M and P-MDQ (r=0.771 and 0.826). This study suggests that the CBCL could be used for measuring mood symptoms and combined psychopathology

    The objective of this study was to observe for efficacy, safety, and compliance of electroacupuncture for autism spectrum disorder (ASD). Two (2) children with ASD received electroacupuncture for 24 sessions over 8 weeks and were assessed pre- and postacupuncture. We defined a positive or negative change as an improvement or deterioration of 25%, respectively, in total score or any subscales of Aberrant Behavioral Checklist (ABC), Ritvo-Freeman Real Life Scale (RFRLS), WeeFIM, and as a rating of much improved or much worse on the Clinical Global Impression-Improvement (CGI-I) scale. For ABC, positive changes in "Irritability" and "Stereotypy" was noted in case 1 but no changes occurred for case 2. For RFRLS, positive changes were found for both cases in "Sensory motor," "Sensory response," and "Total score," although negative change was noted for case 2 in "Affectual response." For WeeFIM, there were no positive or negative changes in both cases. For CGI-I, positive change in case 1 with much improved in "Social relatedness, Communication, and Stereotypy behavior" was reported. A short intensive course of electroacupuncture might improve some core features of children with ASD.

    Thirty adults with Prader-Willi syndrome (PWS) were compared with 30 adults with non-specific learning disability matched for age, sex and severity of mental retardation. Maladaptive behaviour was assessed with the Aberrant Behavior Checklist (ABC), a 58-item structured interview which rates behaviours from 0 (not a problem) to 3 (severe problem) and which yields five factors (I) irritability, agitation; (II) lethargy, withdrawal; (III) stereotypic behavior; (IV) hyperactivity, non-compliance; and (V) inappropriate speech). The PWS sample had significantly higher factor I (P < 0.001) and factor V (P < 0.05) scores. The PWS sample had mean scores above 1 for 17 ABC items; the contrast subjects had no mean scores above 1. The factor I scores for the PWS sample were similar to those of inpatients in hospital facilities for adults with mental retardation and mental illness or severely challenging behaviour. The results support previous work, and extend it by suggesting that temper tantrums, self-injury, impulsiveness, lability of mood, inactivity and repetitive speech are characteristic behaviours in PWS in adult life. Studies of the reasons for heterogeneity in behaviour are now needed.

    There are only a limited number of Dutch validated measurement instruments for measuring behavioral problems in people with a moderate to profound intellectual disability. In this study, the psychometric properties of a Dutch version of the behavior Problems Inventory-01 (BPI-01; Rojahn et al., 2001) have been investigated among 195 people with a moderate to profound intellectual disability who live in a residential facility. The BPI-01 was completed by 42 informants (staff members) of 23 care units. The inter-rater reliability, intra-rater reliability and internal consistency turned out to be good. Factor analysis confirmed two of the three a priori factors and the third factor was a mix of self-injurious (SIB) behavior and stereotypic behavior. The BPI-01 was compared to the Aberrant Behavior Checklist (Aman et al., 1985a) and showed a good convergent validity. This study shows that a Dutch version of the BPI-01 has good psychometric properties for measuring behavior problems in individuals with moderate to profound intellectual disability.

    To review the evidence supporting selected complementary and alternative medicine approaches used in the treatment of irritable bowel syndrome (IBS). MEDLINE (from January 1966), EMBASE (from January 1980), and the Cochrane Database of Systematic Reviews were searched until March 2008, combining the terms irritable bowel syndrome or irritable colon with complementary therapies, alternative medicine, acupuncture, fiber, peppermint oil, herbal, traditional, yoga, massage, meditation, mind, relaxation, probiotic, hypnotherapy, psychotherapy, cognitive therapy, or behavior therapy. Results were screened to include only clinical trials, systematic reviews, and meta-analyses. Level I evidence was available for most interventions. Soluble fibre improves constipation and global IBS symptoms. Peppermint oil alleviates IBS symptoms, including abdominal pain. Probiotic trials show overall benefit for IBS but there is little evidence supporting the use of any specific strain. Hypnotherapy and cognitive-behavioural therapy are also effective therapeutic options for appropriate patients. Certain herbal formulas are supported by limited evidence, but safety is a potential concern. All interventions are supported by systematic reviews or meta-analyses. Several complementary and alternative therapies can be recommended as part of an evidence-based approach to the treatment of IBS; these might provide patients with satisfactory relief and improve the therapeutic alliance.

    Abstract Diet-related chronic health conditions are prevalent in the Filipino American community; however, there is a lack of rigorously validated nutrition education evaluation tools in Tagalog for use in this population. This study aimed to develop and evaluate the face validity of a Tagalog-language food behavior checklist (FBC). A multi-step method was used, involving translation of questionnaire text from English to Tagalog by a team of professionals, creation of accompanying color photographs, cognitive testing with the target population, final review by the team of professionals, and assessment of readability. Subjects for cognitive testing were men (n=6) and women (n=14) 18 years or older in Hawai‘i who received or were eligible to receive Supplemental Nutrition Assistance Program (SNAP) benefits, self-identified as Filipino, and preferred Tagalog rather than English. Participants were recruited from churches, the Filipino Center, and other community sites. Cognitive interviews revealed several issues with text and photographs, such as preferences for specific terms, and images that did not adequately illustrate the text. Image changes were made to reflect items most commonly consumed. The team of professionals agreed with participant suggestions. Assessment of readability revealed a reading level appropriate for a low-literacy population of grade 5.9. The multi-step process, which allowed members of the target audience to reveal the appropriateness of the questionnaire, yielded a Tagalog-language FBC found to have adequate face validity. After further evaluation of validity and reliability, this tool may be used to evaluate behavior change resulting from the United States Department of Agriculture's (USDA) nutrition education programs.

    The 2009 World Health Organisation (WHO) surgical safety checklist significantly reduces surgical mortality and morbidity (up to 47%). Yet in 2016, only 25% of East African anesthetists regularly use the checklist. Nationwide implementation of the checklist is reported in high-income countries, but in low- and middle-income countries (LMICs) reports of successful implementations are sparse, limited to single institutions and require intensive support. Since checklist use leads to the biggest improvements in outcomes in LMICs, methods of wide-scale implementation are needed. We hypothesized that, using a three-day course, successful wide-scale implementation of the checklist could be achieved, as measured by at least 50% compliance with six basic safety processes at three to four months. We also aimed to determine predictors for checklist utilization. Using a blended educational implementation strategy based on prior pilot studies we designed a three-day dynamic educational course to facilitate widespread implementation of the WHO checklist. The course utilized lectures, film, small group breakouts, participant feedback and simulation to teach the knowledge, skills and behavior changes needed to implement the checklist. In collaboration with the Ministry of Health and local hospital leadership, the course was delivered to 427 multi-disciplinary staff at 21 hospitals located in 19 of 22 regions of Madagascar between September 2015 and March 2016. We evaluated implementation at three to four months using questionnaires (with a 5-point Likert scale) and focus groups. Multivariate linear regression was used to test predictors of checklist utilization. At three to four months, 65% of respondents reported always using the checklist, with another 13% using it in part. Participant's years in practice, hospital size, or surgical volume did not predict checklist use. Checklist use was associated with counting instruments (p< 0.05), but not with verifying: patient identity

    This study aimed at investigating the efficacy and tolerability of l-carnosine as an add-on to risperidone in the management of children with autism. This was a 10-week, randomized, double-blind, placebo-controlled study. Seventy drug-free children aged 4-12 years old with a diagnosis of autism spectrum disorder (ASD), according to the Diagnostic and Statistical Manual of Mental Disorders, fifth edition. (DSM-5) who had an Aberrant Behavior Checklist-Community (ABC-C) scale irritability subscale score of ≥12, entered the study. The patients were randomly assigned to l-carnosine (800 mg/day in 2 divided doses) or placebo in addition to risperidone titrated up to 2 mg/day (based on body weight) for 10 weeks. The children were assessed by using ABC-C at baseline and weeks 5 and 10 post-baseline. The primary outcome measure was the mean change in the ABC-C irritability subscale score, and other subscale scores were defined as secondary outcomes. Using the general linear model repeated measures, no significant effect was observed for time × treatment interaction on the irritability subscale scores. However, significant effect was detected on the hyperactivity/noncompliance subscale [F (1.62, 64.96) = 3.53, p-value = 0.044]. No significant improvements were obtained on the lethargy/social withdrawal, stereotypic behavior, and inappropriate speech subscale scores. Significantly greater score reduction in the hyperactivity/noncompliance subscale occurred in the l-carnosine group compared with the placebo group at the end of the trial. Extrapyramidal Symptom Rating Scale Scores and its changes did not differ between the two groups. The frequency of other side effects was not significantly different between the two groups. Although no significant difference was detected on the irritability subscale scores, l-carnosine add-on can improve hyperactivity/noncompliance subscales of the ABC-C rating scale in patients with ASD.

    Irritability is a common long-term sequelae of traumatic brain injury (TBI). In a prior study on TBI irritability, relational interactions were one of four dimensions of irritability occurrence and precipitation. This present analysis examines these same data in greater detail. Fifty focus group transcripts from a study on irritability were re-analysed to examine: (1) irritability in spousal relationships following TBI, (2) retrospective accounts of spousal interactions contributing to irritability and (3) impact of irritability on marital relationships. Grounded Theory was used to develop themes, metacodes and theories. Several theories emerged regarding irritability with respect to spousal relations, all based on the overarching theory that irritability in people with TBI has a strong relational component involved in triggering, experiencing and preventing irritability. Sub-theories supporting this include: (1) irritability breeds further irritability, (2) spousal responses can trigger irritability among persons with TBI and vice versa, (3) difficulties making emotional connections may incite negative interactions, (4) expectations of others may contribute to irritable behaviour, and (5) communication breakdowns may provoke irritability. Irritability associated with TBI resides in the family system as well as the individual. In treating irritability one should include comprehensive assessment and assistance to improve interpersonal interactions.

    To assess the structural overlap between the Behavior Rating Inventory of Executive Function (BRIEF) and Achenbach Child Behavior Checklist (CBCL) among children in Uganda. Caregiver ratings for the BRIEF and CBCL were obtained for 2 independent samples of school-aged children: 106 children (5-12 years old, 50% males) with a history of severe malaria and on 144 HIV-infected children (5-12 years old, 58% males) in Uganda. Exploratory factor analysis was used to evaluate the factor structure of the 8 subscales for the BRIEF and the 8 scales of the CBCL to determine correlation. Overall, children in the severe malaria group had higher (increased symptom) BRIEF and CBCL scores than those in the HIV-infected group. Three factors that provided a reasonable fit to the data and could be characterized as 3 specific domains were identified: (1) Metacognition, which consisted of the scales in the BRIEF Metacognition domain, (2) Behavioral Adjustment, which comprised of the scales in the BRIEF Behavioral Regulation domain and the Externalizing Symptoms scales in the CBCL, and (3) Emotional Adjustment, which mainly consisted of the Internalizing Symptoms scales in the CBCL. The BRIEF Behavior Regulation and CBCL Externalizing Symptoms scales, however, did overlap in terms of assessing similar behavior symptoms. These findings were consistent across the severe malaria and HIV-infected samples of children. The BRIEF and CBCL instruments offer distinct, yet complementary, assessments of behavior in clinical pediatric populations in the Ugandan context, supporting the use of these measures for similar research settings.

    The purpose of this study was to evaluate the local tolerance of vaginal gels (three gels containing dapivirine, the placebo gel, and Conceptrol) with the Slug Mucosal Irritation test and to compare the results with those of the rabbit vaginal irritation test. The irritation potential on the slug mucosa was assessed by the mucus production caused by a repeated treatment for 5 successive days. Additionally, membrane damage was estimated by the protein and enzyme release. By means of a classification prediction model the formulations were classified into four irritation classes. The effect of a 10-day intravaginal application of the gels on the rabbit vaginal and cervical mucosa was evaluated by means of macroscopic and microscopic examination. The placebo and dapivirine gels induced no irritation of the slug mucosa (low mucus production and protein release, no enzyme release) and no vaginal or cervical irritation in rabbits. Conceptrol caused severe irritation of the slug mucosa (increased mucus production, protein release, and enzyme release) and irritation of the rabbit vagina and cervix. The results obtained with the Slug Mucosal Irritation test were comparable to those of the rabbit vaginal irritation test.

    In a laboratory study, the irritancy of bendiocarb, lambda-cyhalothrin and DDT to Anopheles gambiae was evaluated at field, 1/3 field and 1/10 field rates using WHO conical exposure chambers and excito-repellency test boxes. Bendiocarb was the least irritant insecticide at all rates, inducing levels of takeoff, flight and exiting behavior similar to those of a distilled water control treatment. Of those mosquitoes introduced to the bendiocarb-treated boxes, not more than 1% exited and survived at any dose rate. Lambda-cyhalothrin and DDT were highly irritant to An. gambiae, inducing a strong stimulation to take off and fly and also a high level of exiting. Exiting-survival rates associated with lambda-cyhalothrin and DDT were between 15 and 51%. The relevance of these findings to the control of mosquito populations and the prevention of malaria transmission is discussed.

    A generic method to determine the aberration center is established, which can be utilized for aberration calculation and axis alignment for aberration corrected electron microscopes. In this method, decentering induced secondary aberrations from inherent primary aberrations are minimized to find the appropriate axis center. The fitness function to find the optimal decentering vector for the axis was defined as a sum of decentering induced secondary aberrations with properly distributed weight values according to the aberration order. Since the appropriate decentering vector is determined from the aberration values calculated at an arbitrary center axis, only one aberration measurement is in principle required to find the center, resulting in /very fast center search. This approach was tested for the Ronchigram based aberration calculation method for aberration corrected scanning transmission electron microscopy. Both in simulation and in experiments, the center search was confirmed to work well although the convergence to find the best axis becomes slower with larger primary aberrations. Such aberration center determination is expected to fully automatize the aberration correction procedures, which used to require pre-alignment of experienced users. This approach is also applicable to automated aperture positioning. Copyright © 2013 Elsevier B.V. All rights reserved.

    Skew Parametric-resonance Ionization Cooling (Skew PIC) represents a novel method for focusing of highly divergent particle beams, as in the final 6D cooling stage of a high-luminosity muon collider. In the muon collider concept, the resultant equilibrium transverse emittances from cooling with Skew PIC are an order of magnitude smaller than in conventional ionization cooling. The concept makes use of coupling of the transverse dynamic behavior, and the linear dynamics are well-behaved with good agreement between analytic solutions and simulation results. Compared to the uncoupled system, coupling of the transverse dynamic behavior purports to reduce the number of multipoles requiredmore » for aberration compensation while also avoiding unwanted resonances. Aberration compensation is more complicated in the coupled case, especially in the high-luminosity muon collider application where equilibrium angular spreads in the cooling channel are on the order of 200 mrad. We present recent progress on aberration compensation for control of highly divergent muon beams in the coupled correlated optics channel, and a simple cooling model to test the transverse acceptance of the channel.« less

    To evaluate the diagnostic value of the rectal sensory threshold for pain (RSTP) in children and adolescents with chronic abdominal pain. Fifty-one patients (25 girls; median age 14.2 years; range 8.4-17.6) with abdominal pain >2 months underwent a series of rectal distensions with an electronic barostat. RSTP and viscerosomatic referrals were assessed. Three months after the barostat, the final diagnosis was documented. Thirty-five patients had a functional gastrointestinal disorder (FGID) (irritable bowel syndrome or functional abdominal pain), and 16 had an organic disease. RSTP was lower in the FGID group than in the organic disease group (25.4mm Hg vs 37.1mm Hg; P = .0002). At the cutoff of 30mm Hg, the RSTP measurement for the diagnosis of FGID had a sensitivity of 94% and a specificity of 77%. Both groups similarly reported aberrant viscerosomatic projections. In children, RSTP is a diagnostic marker of irritable bowel syndrome and functional abdominal pain. Viscerosomatic referrals are similar in children with FGID and organic diseases.

    In a recent paper, Kuchner, Crepp, and Ge describe new image-plane coronagraph mask designs that reject to eighth order the leakage of starlight caused by image motion at the mask, resulting in a substantial relaxation of image centroiding requirements compared to previous fourth-order and second-order masks. They also suggest that the new masks are effective at rejecting leakage caused by low-order aberrations (e.g., focus, coma, and astigmatism). In this paper, we derive the sensitivity of eighth-order masks to aberrations of any order and provide simulations of coronagraph behavior in the presence of optical aberrations.We find that the masks leak light as the fourth power of focus, astigmatism, coma, and trefoil. This has tremendous performance advantages for the Terrestrial Planet Finder Coronagraph.

    This study aimed to investigate the effect of adding amantadine to risperidone for treatment of autism. Forty outpatients aged 4 to12 years, who were diagnosed with autism spectrum disorders based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria, were assigned to this double-blind clinical trial. The subjects were divided randomly into 2 groups. One group received risperidone plus amantadine, and the other group received risperidone plus placebo. The dose of risperidone was titrated between 1 and 2.0 mg/d, and the dose of amantadine was 100 or 150 mg/d for patients less than 30 kg or more than 30 kg, respectively. The patients were assessed using the Aberrant Behavioral Checklist-Community (ABC-C) and adverse effects checklist as well as clinical global impression-improvement (CGI-I) at2 checkpoints of 5-week intervals after the baseline. Informed consentwas obtained from the parents of each participant. Among ABC-C subscales, Hyperactivity and Irritability showed significantly greater reduction in the amantadine group than the placebo group. There was no significant difference in adverse effects between the 2 groups. The CGI-I scores show significant improvement in the amantadine group compared to the placebo group. The present study suggests that amantadine may be a potential adjunctive treatment strategy for autism and it was generally well tolerated.

    Abstract Objective: Risperidone has demonstrated efficacy for acute (8 week) and intermediate length (6 month) management of severe irritability and aggression in children and adolescents with autism. Less is known about the long-term effects of risperidone exposure in this population. We examined the tolerability, safety, and therapeutic benefit of risperidone exposure over a 1–2 year follow-up period. Methods: In a naturalistic study, 84 children and adolescents 5–17 years of age (from an original sample of 101) were assessed an average of 21.4 months after initial entry into a placebo-controlled 8 week trial of risperidone for children and adolescents with autism and severe irritability. They were assessed at baseline and at follow-up on safety and tolerability measures (blood, urinalysis, electrocardiogram [ECG], medical history, vital signs, neurological symptoms, other adverse events), developmental measures (adaptive behavior, intelligence quotient [IQ]), and standardized rating instruments. Treatment over the follow-up period, after completion of protocol participation, was uncontrolled. Statistical analyses assessed outcome over time with or without prolonged risperidone therapy. Results: Two-thirds of the 84 subjects continued to receive risperidone (mean 2.47 mg/day, S.D. 1.29 mg). At follow-up, risperidone was associated with more enuresis, more excessive appetite, and more weight gain, but not more adverse neurological effects. No clinically significant events were noted on blood counts, chemistries, urinalysis, ECG, or interim medical history. Regardless of drug condition at follow-up, there was considerable improvement in maladaptive behavior compared with baseline, including core symptoms associated with autism. Height and weight gains were elevated with risperidone. Social skills on Vineland Adaptive Behavior Scale (VABS) improved with risperidone.

    Background The 2009 World Health Organisation (WHO) surgical safety checklist significantly reduces surgical mortality and morbidity (up to 47%). Yet in 2016, only 25% of East African anesthetists regularly use the checklist. Nationwide implementation of the checklist is reported in high-income countries, but in low- and middle-income countries (LMICs) reports of successful implementations are sparse, limited to single institutions and require intensive support. Since checklist use leads to the biggest improvements in outcomes in LMICs, methods of wide-scale implementation are needed. We hypothesized that, using a three-day course, successful wide-scale implementation of the checklist could be achieved, as measured by at least 50% compliance with six basic safety processes at three to four months. We also aimed to determine predictors for checklist utilization. Materials and methods Using a blended educational implementation strategy based on prior pilot studies we designed a three-day dynamic educational course to facilitate widespread implementation of the WHO checklist. The course utilized lectures, film, small group breakouts, participant feedback and simulation to teach the knowledge, skills and behavior changes needed to implement the checklist. In collaboration with the Ministry of Health and local hospital leadership, the course was delivered to 427 multi-disciplinary staff at 21 hospitals located in 19 of 22 regions of Madagascar between September 2015 and March 2016. We evaluated implementation at three to four months using questionnaires (with a 5-point Likert scale) and focus groups. Multivariate linear regression was used to test predictors of checklist utilization. Results At three to four months, 65% of respondents reported always using the checklist, with another 13% using it in part. Participant’s years in practice, hospital size, or surgical volume did not predict checklist use. Checklist use was associated with counting instruments (p< 0

    Objectives To assess the current use of safety checklists among the American College of Phlebology (ACP) members and their interest in implementing a checklist supported by the ACP on their clinical practices; and to develop a phlebology safety checklist. Method Online surveys were sent to ACP members, and a phlebology safety checklist was developed by a multispecialty team through the ACP Leadership Academy. Results Forty-seven percent of respondents are using a safety checklist in their practices; 23% think that a phlebology safety checklist would interfere or disrupt workflow; 79% answered that a phlebology safety checklist could improve procedure outcomes or prevent complications; and 85% would be interested in implementing a phlebology safety checklist approved by the ACP. Conclusion A phlebology safety checklist was developed with the intent to increase awareness on patient safety and improve outcome in phlebology practice.

  1. Influence of alignment errors of a telescope system on its aberration field

    The study of aberrations in a system is considered. It is pointed out that a system in which the elements are tilted and decentered has no axial symmetry, and in fact no symmetry at all if the tilts, and decentrations are not coplanar. It is customary in such a case to give up on an aberration-theoretic treatment and simply trace enough rays to produce a set of spot diagrams for various points in the field. However, in connection with the lack of symmetry, it is necessary to select a relatively large number of points. The considered investigation is concerned with an aberration-theoretic approach which can be applied to such systems. This approach provides insight into the field behavior of the aberrations with great economy in the calculation. It is based on a concept suggested by Buchroeder (1976). In the given case, this concept considers for the component fields corresponding to the various surfaces centers of symmetry which do not coincide. Attention is given to the procedure for locating the centers of symmetry, aberrations fields, spherical aberration, and various types of astigmatism.

    Evaluating whether parental challenges and self-efficacy toward managing children's lifestyle behaviors are successfully addressed by interventions requires valid instruments. The Lifestyle Behavior Checklist (LBC) has recently been developed in the Australian context. It consists of two subscales: the Problem scale, which measures parental perceptions of children's behavioral problems related to overweight and obesity, and the Confidence scale, measuring parental self-efficacy in dealing with these problems. The aim of the current study was to systematically translate the questionnaire into Dutch and to evaluate its internal consistency, construct validity and test-retest reliability. The LBC was systematically translated by four experts at Maastricht University. In total, 392 parents of 3-to13-year-old children were invited to fill out two successive online questionnaires with a two-week interval. Of these, 273 parents responded to the first questionnaire (test, response rate = 69.6%), and of the 202 who could be invited for the second questionnaire (retest), 100 responded (response rate = 49.5%). We assessed the questionnaire's internal consistency (Cronbach's α), construct validity (Spearman's Rho correlation tests, using the criterion measures: restrictiveness, nurturance, and psychological control), and test-retest reliability (Spearman's Rho correlation tests). Both scales had high internal consistency (Cronbach's α ≥ 0.90). Spearman correlation coefficients indicated acceptable test-retest reliability for both the Problem scale (rs = 0.74) and the Confidence scale (rs = 0.70). The LBC Problem scale was significantly correlated to all criterion scales (nurturance, restrictiveness, psychological control) in the hypothesized direction, and the LBC Confidence scale was significantly correlated with nurturance and psychological control in the hypothesized direction, but not with restrictiveness. The Dutch translation of the LBC was found to be a reliable and

    Objective Irritability is a prominent symptom in the spectrum of female-specific mood disorders, and in some women, irritability is serious enough to disrupt their lives and warrant treatment. The objective of this research was to develop a new, female-specific state measure of irritability. Methods We constructed self-rating and observer rating scales using items derived from spontaneous descriptions of irritability by women with mood disturbances related to the menstrual cycle, childbearing or menopause. Following a pretest, the scales were shortened to the core items of irritability (annoyance, anger, tension, hostility, sensitivity to noise and touch) and tested on a new cohort of patients. Results The 14-item Self-Rating Scale and the 5-item Observer Rating Scale showed evidence for internal consistency (Self-Rating: n = 36 patients, Cronbach's α = 0.9257, mean interitem correlation = 0.4690; Observer Rating: Cronbach's α = 0.7418, mean interitem correlation = 0.3616), Self-Rating test–retest reliability (n = 29 patients, rs = 0.704, p = 0.01) and interrater reliability (n = 20 patients; τb = 1.000, p = 0.001). Conclusion This new, female-specific scale for rating irritability has the potential to further the evaluation of this prominent symptom cluster and increase specificity in clinical assessments of emotional disturbances related to reproductive cyclicity in women.

    Irritant contact dermatitis (ICD) is a common diagnosis in patients with occupational contact dermatitis (OCD). Studies are lacking on the usefulness of material safety data sheets (MSDSs) in making the diagnosis of ICD. To characterize irritant exposures leading to the diagnosis of occupational ICD (OICD), and to evaluate the occurrence of concomitant exposures to contact allergens. We included 316 patients with suspected occupational hand dermatitis, referred to the Department of Dermato-Allergology, Copenhagen University Hospital Gentofte, Denmark during January 2010-August 2011, in a programme consisting of a clinical examination, exposure assessment, and extensive patch/prick testing. OCD was diagnosed in 228 patients. Of these patients, 118 were diagnosed with OICD. The main irritant exposures identified were wet work (n = 64), gloves (n = 45), mechanical traumas (n = 19), and oils (n = 15). Exposure to specific irritant chemicals was found in 9 patients, and was identified from MSDSs/ingredients labelling in 8 of these patients. Review of MSDSs and ingredients labelling showed that 41 patients were exposed to 41 moderate to potent contact allergens, and 18 patients were exposed to 25 weak workplace contact allergens. In the present study, the systematic exposure assessment did not reveal any new irritants. MSDSs have a limited role in the investigation of ICD. © 2014 John Wiley & Sons A/S.

    Single or multiple applications of irritants can lead to occupational contact dermatitis, and most commonly irritant contact dermatitis (ICD). Tandem irritation, the sequential application of two irritants to a target skin area, has been studied using the Tandem Repeated Irritation Test (TRIT) to provide a more accurate representation of skin irritation. Here we present an update to Kartono's review on tandem irritation studies since 2006 [1]. We surveyed the literature available on PubMed, Embase, Google Scholar, and the UCSF Dermatology library databases since 2006. The studies included discuss the tandem effects of common chemical irritants, organic solvents, occlusion as well as clinical relevance - and enlarge our ability to discern whether multiple chemical exposures are more or less likely to enhance irritation.

    A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of the global liverwort and hornwort flora. The checklist is derived from a working data set centralizing nomenclature, taxonomy and geography on a global scale. Prior to this effort a lack of centralization has been a major impediment for the study and analysis of species richness, conservation and systematic research at both regional and global scales. The success of this checklist, initiated in 2008, has been underpinned by its community approach involving taxonomic specialists working towards a consensus on taxonomy, nomenclature and distribution.

    Ionizing radiation can damage cells by breaking both strands of DNA in multiple locations, essentially cutting chromosomes into pieces. The cell has enzymatic mechanisms to repair such breaks; however, these mechanisms are imperfect and, in an exchange process, may produce a large-scale rearrangement of the genome, called a chromosome aberration. Chromosome aberrations are important in killing cells, during carcinogenesis, in characterizing repair/misrepair pathways, in retrospective radiation biodosimetry, and in a number of other ways. DNA staining techniques such as mFISH ( multicolor fluorescent in situ hybridization) provide a means for analyzing aberration spectra by examining observed final patterns. Unfortunately, an mFISH observed final pattern often does not uniquely determine the underlying exchange process. Further, resolution limitations in the painting protocol sometimes lead to apparently incomplete final patterns. We here describe an algorithm for systematically finding exchange processes consistent with any observed final pattern. This algorithm uses aberration multigraphs, a mathematical formalism that links the various aspects of aberration formation. By applying a measure to the space of consistent multigraphs, we will show how to generate model-specific distributions of aberration processes from mFISH experimental data. The approach is implemented by software freely available over the internet. As a sample application, we apply these algorithms to an aberration data set, obtaining a distribution of exchange cycle sizes, which serves to measure aberration complexity. Estimating complexity, in turn, helps indicate how damaging the aberrations are and may facilitate identification of radiation type in retrospective biodosimetry.

    The Dysregulation Profile (DP) is a broad indicator of concurrent affective, behavioral, and cognitive dysregulation, often measured with the anxious/depressed, aggressive behavior, and attention problems syndrome scales of the Child Behavior Checklist. Despite an expanding body of research on the DP, knowledge of the normative developmental course of the DP from early childhood to adolescence is lacking. Furthermore, although we know that the DP longitudinally predicts personality pathology, no research yet has examined whether next to the DP in early childhood, the rate of change of the DP across development predicts personality pathology. Therefore, using cohort-sequential latent growth modeling in a population-based sample (N = 668), we examined the normative developmental course of mother-reported DP from ages 4 to 17 years and its associations with a wide range of adolescent-reported personality pathology dimensions 3 years later. The results showed that the DP follows a nonlinear developmental course with a peak in early adolescence. The initial level of the DP at age 4 and, to a lesser extent, the rate of change in the DP predicted a range of personality pathology dimensions in late adolescence. The findings suggest that the DP is a broad developmental precursor of personality pathology in late adolescence.

    Psychological aspects of Irritable Bowel Syndrome have been well investigated in Western countries, but there is a paucity of Indian studies focusing on this area. A series of fifty patients with the Irritable Bowel Syndrome were studied with respect to their depressive symptoms, anxiety symptoms and their personality traits. Patients had a mean score of 14.68 on Hamilton's depression rating scale and 11.22 on Hamilton's anxiety rating scale, and were more introverted and more neurotic than the general population. No association was found between psychological symptoms and severity of gastrointestinal symptoms. These findings suggest that psychological symptoms are a concomitant part of the Irritable Bowel Syndrome. PMID:21584134

    Combat casualty care is distributed across professions and echelons of care. Communication within it is fragmented, inconsistent, and prone to failure. Daily checklists used during intensive care unit (ICU) rounds have been shown to improve compliance with evidence-based practices, enhance communication, promote consistency of care, and improve outcomes. Checklists are criticized because it is difficult to establish a causal link between them and their effect on outcomes. We investigated how checklists used during ICU rounds affect communication. We conducted this project in two military ICUs (burn and surgical/trauma). Checklists contained up to 21 questions grouped according to patient population. We recorded which checklist items were discussed during rounds before and after implementation of a "must address" checklist and compared the frequency of discussing items before checklist prompting. Patient discussions addressed more checklist items before prompting at the end of the 2-week evaluation compared with the 2-week preimplementation period (surgical trauma ICU, 36% vs. 77%, p < 0.0001; burn ICU, 47% vs. 72 %, p < 0.001). Most items were addressed more frequently in both ICUs after implementation. Key items such as central line removal, reduction of laboratory testing, medication reconciliation, medication interactions, bowel movements, sedation holidays, breathing trials, and lung protective ventilation showed significant improvements. Checklists modify communication patterns. Improved communication facilitated by checklists may be one mechanism behind their effectiveness. Checklists are powerful tools that can rapidly alter patient care delivery. Implementing checklists could facilitate the rapid dissemination of clinical practice changes, improve communication between echelons of care and between individuals involved in patient care, and reduce missed information.

    Emotional dysregulation in childhood has been associated with various forms of later psychopathology, although no studies have investigated the personality related adolescent outcomes associated with early emotional dysregulation. The present study uses a typological approach to examine how the child behavior checklist-dysregulation profile (CBCL-DP) predicts DSM-5 pathological personality traits (as measured with the personality inventory for the diagnostic and statistical manual of mental disorders 5 or PID-5 by Krueger et al. (Psychol Med 2012)) across a time span of 4 years in a sample of 243 children aged 8-14 years (57.2 % girls). The results showed that children assigned to the CBCL-DP class are at risk for elevated scores on a wide range of DSM-5 personality pathology features, including higher scores on hostility, risk taking, deceitfulness, callousness, grandiosity, irresponsibility, impulsivity and manipulativeness. These results are discussed in the context of identifying early manifestations of persistent regulation problems, because of their enduring impact on a child's personality development.

    Background Surgical complications represent a significant cause of morbidity and mortality with the rate of major complications after inpatient surgery estimated at 3–17% in industrialised countries. The purpose of this review was to summarise experience with surgical checklist use and efficacy for improving patient safety. Methods A search of four databases (MEDLINE, CINAHL, EMBASE and the Cochrane Database of Controlled Trials) was conducted from 1 January 2000 to 26 October 2012. Articles describing actual use of the WHO checklist, the Surgical Patient Safety System (SURPASS) checklist, a wrong-site surgery checklist or an anaesthesia equipment checklist were eligible for inclusion (this manuscript summarises all but the anaesthesia equipment checklists, which are described in the Agency for Healthcare Research and Quality publication). Results We included a total of 33 studies. We report a variety of outcomes including avoidance of adverse events, facilitators and barriers to implementation. Checklists have been adopted in a wide variety of settings and represent a promising strategy for improving the culture of patient safety and perioperative care in a wide variety of settings. Surgical checklists were associated with increased detection of potential safety hazards, decreased surgical complications and improved communication among operating staff. Strategies for successful checklist implementation included enlisting institutional leaders as local champions, incorporating staff feedback for checklist adaptation and avoiding redundancies with existing systems for collecting information. Conclusions Surgical checklists represent a relatively simple and promising strategy for addressing surgical patient safety worldwide. Further studies are needed to evaluate to what degree checklists improve clinical outcomes and whether improvements may be more pronounced in particular settings. PMID:23922403

The 10 domains in the checklist are essentially physical characteristics of places. Each domain has relevance to the health of people living in the place, and to the sustainability of the environment. The checklist is intended as a tool for those who plan, develop and manage urban environments. Such tools can be valuable for assessing the health and environmental impacts of decisions made by urban and transport planners, and businesses engaged in land development and infrastructure projects.

  1. The effect of spherical aberration on the phase singularities of focused dark-hollow Gaussian beams

    NASA Astrophysics Data System (ADS)

    Luo, Yamei; Lü, Baida

    2009-06-01

    The phase singularities of focused dark-hollow Gaussian beams in the presence of spherical aberration are studied. It is shown that the evolution behavior of phase singularities of focused dark-hollow Gaussian beams in the focal region depends not only on the truncation parameter and beam order, but also on the spherical aberration. The spherical aberration leads to an asymmetric spatial distribution of singularities outside the focal plane and to a shift of singularities near the focal plane. The reorganization process of singularities and spatial distribution of singularities are additionally dependent on the sign of the spherical aberration. The results are illustrated by numerical examples.

    2016-01-01

    An updated checklist of 235 mosquito species from Madagascar is presented. The number of species has increased considerably compared to previous checklists, particularly the last published in 2003 (178 species). This annotated checklist provides concise information on endemism, taxonomic position, developmental stages, larval habitats, distribution, behavior, and vector-borne diseases potentially transmitted. The 235 species belong to 14 genera: Aedeomyia (3 species), Aedes (35 species), Anopheles (26 species), Coquillettidia (3 species), Culex (at least 50 species), Eretmapodites (4 species), Ficalbia (2 species), Hodgesia (at least one species), Lutzia (one species), Mansonia (2 species), Mimomyia (22 species), Orthopodomyia (8 species), Toxorhynchites (6 species), and Uranotaenia (73 species). Due to non-deciphered species complexes, several species remain undescribed. The main remarkable characteristic of Malagasy mosquito fauna is the high biodiversity with 138 endemic species (59%). Presence and abundance of species, and their association, in a given location could be a bio-indicator of environmental particularities such as urban, rural, forested, deforested, and mountainous habitats. Finally, taking into account that Malagasy culicidian fauna includes 64 species (27%) with a known medical or veterinary interest in the world, knowledge of their biology and host preference summarized in this paper improves understanding of their involvement in pathogen transmission in Madagascar.

    Introduction  For the long-term treatment of obstructive lung diseases inhalation therapy with drugs being delivered directly to the lungs as an aerosol has become the method of choice. However, patient-related mistakes in inhalation techniques are frequent and recognized to be associated with reduced disease control. Since the assessment of patient-mistakes in inhalation has yet not been standardized, the present study was aimed at developing checklists for the assessment of correct inhalation. Methods  Checklists were developed in German by an expert panel of pneumologists and professionally translated into English following back-translation procedures. The checklists comparably assessed three major steps of inhalation: 1) inhalation preparation, 2) inhalation routine, and 3) closure of inhalation. Results  Checklists for eight frequently used inhalers were developed: Aerolizer, Breezhaler, Diskus (Accuhaler), metered-dose inhaler, Handihaler, Novolizer, Respimat, Turbohaler. Each checklist consists of ten items: three for inhalation preparation, six for inhalation routine, and one for closure of inhalation. Discussion  Standardized checklists for frequently used inhalers are available in German and English. These checklists can be used for clinical routines or for clinical trials. All checklists can be downloaded free of charge for non-profit application from the homepage of the German Airway League (Deutsche Atemwegsliga e. V.): www.atemwegsliga.de. © Georg Thieme Verlag KG Stuttgart · New York.

    Fellows in pulmonary and critical care medicine are required to show competency in facilitating family meetings for critically ill patients. There are many assessment measures available for evaluating physician-patient communication (e.g., the SEGUE Framework [Set the stage, Elicit information, Give information, Understand the patient's perspective, End the encounter]) and some designed for family meetings. However, no validated measure exists that is specifically designed to assess communication skills during family meetings with surrogate decision makers in intensive care settings. We developed the Family Meeting Behavioral Skills Checklist (FMBSC) to measure advanced communication skills of fellows in family meetings of critically ill patients based on a literature review and consensus of an interdisciplinary group of communications experts. We evaluated the psychometric properties of the FMBSC. We digitally recorded 16 pulmonary/critical care fellows performing a simulated family meeting for a critically ill patient at the end of 1 year of fellowship training. Two clinical health psychologists evaluated each recording independently using the FMBSC Rating Scale and the SEGUE Framework. Judges recorded the number of skills performed using the checklist and employed a summary rating scale to judge the level of performance for each of nine subsets of skills. Each instrument was scored and converted to percentage scores. The FMBSC and SEGUE Framework items were summed and converted to percentage scores for each category and as a total for each instrument. The rating scale items on the FMBSC were also summed and converted to a percentage score. Four primary analyses were conducted to evaluate interjudge reliability, internal consistency, and concurrent validity. Interrater reliability was higher for the FMBSC (intraclass correlation [ICC2,2] = 0.57) than for the SEGUE instrument (ICC2,2 = 0.32) or the FMBSC Rating Scale (ICC2,2 = 0.23). The FMBSC

    To develop a specific RADiological Patient Safety System (RADPASS) checklist for interventional radiology and to assess the effect of this checklist on health care processes of radiological interventions. On the basis of available literature and expert opinion, a prototype checklist was developed. The checklist was adapted on the basis of observation of daily practice in a tertiary referral centre and evaluation by users. To assess the effect of RADPASS, in a series of radiological interventions, all deviations from optimal care were registered before and after implementation of the checklist. In addition, the checklist and its use were evaluated by interviewingmore » all users. The RADPASS checklist has two parts: A (Planning and Preparation) and B (Procedure). The latter part comprises checks just before starting a procedure (B1) and checks concerning the postprocedural care immediately after completion of the procedure (B2). Two cohorts of, respectively, 94 and 101 radiological interventions were observed; the mean percentage of deviations of the optimal process per intervention decreased from 24 % before implementation to 5 % after implementation (p < 0.001). Postponements and cancellations of interventions decreased from 10 % before implementation to 0 % after implementation. Most users agreed that the checklist was user-friendly and increased patient safety awareness and efficiency. The first validated patient safety checklist for interventional radiology was developed. The use of the RADPASS checklist reduced deviations from the optimal process by three quarters and was associated with less procedure postponements.« less

    Recently we developed and validated generic quality indicators that define 'appropriate antibiotic use' in hospitalized adults treated for a (suspected) bacterial infection. Previous studies have shown that with appropriate antibiotic use a reduction of 13% of length of hospital stay can be achieved. Our main objective in this project is to provide hospitals with an antibiotic checklist based on these quality indicators, and to evaluate the introduction of this checklist in terms of (cost-) effectiveness. The checklist applies to hospitalized adults with a suspected bacterial infection for whom antibiotic therapy is initiated, at first via the intravenous route. A stepped wedge study design will be used, comparing outcomes before and after introduction of the checklist in nine hospitals in the Netherlands. At least 810 patients will be included in both the control and the intervention group. The primary endpoint is length of hospital stay. Secondary endpoints are appropriate antibiotic use measured by the quality indicators, admission to and duration of intensive care unit stay, readmission within 30 days, mortality, total antibiotic use, and costs associated with implementation and hospital stay. Differences in numerical endpoints between the two periods will be evaluated with mixed linear models; for dichotomous outcomes generalized estimating equation models will be used. A process evaluation will be performed to evaluate the professionals' compliance with use of the checklist. The key question for the economic evaluation is whether the benefits of the checklist, which include reduced antibiotic use, reduced length of stay and associated costs, justify the costs associated with implementation activities as well as daily use of the checklist. If (cost-) effective, the AB-checklist will provide physicians with a tool to support appropriate antibiotic use in adult hospitalized patients who start with intravenous antibiotics.

    Irritable bowel syndrome is a functional gastrointestinal illness, defined by symptoms. Irritable bowel syndrome has been described as a biopsychosocial condition, in which colonic dysfunction is affected by psychological and social factors. As a result of this unusual constellation, irritable bowel syndrome may be subject to cultural variables that differ in different parts of the globe. In this article, we describe some of the ways in which irritable bowel syndrome may be experienced differently, depending on local belief systems, psychological pressures, acceptance or resistance to a mind-body paradigm, and breakdown in support or relationship structure. Examples are given in which irritable bowel syndrome investigators from countries around the world describe various aspects of the syndrome that may affect the illness experience of their patients. We describe our own research studies that have demonstrated possible adverse effects on disease severity from relationship conflict, attribution of symptoms to physical rather than emotional cause, and the belief that irritable bowel syndrome is enduring and mysterious. Also described is our finding that symptom patterns may differ significantly between different geographic locations. Finally, we discuss the importance of "cultural competence" on the part of healthcare professionals in regard to caring for patients of diverse cultural backgrounds. © 2010 Mount Sinai School of Medicine.

    Addiction is a chronic compulsion and relapsing disorder. It involves several brain areas and circuits, which encode vary functions such as reward, motivation, and memory. Drug addiction is defined as a "pathological pattern of use of a substance", characterized by the loss of control on drug-taking-related behaviors, the pursuance of those behaviors even in the presence of negative consequences, and a strong motivated activity to assume substances. Three different theories guide experimental research on drug addiction. Each of these theories consider singles features, such as an aberrant motivation, a hedonic dysregulation, and an aberrant habit learning as the main actor to explain the entire process of the addictive behaviors. The major goal of this study is to present a new hypotheses of transitionality from a controlled use to abuse of addictive substances trough the overview of the three different theories, considering all the single features of each single theory together on the same "temporal continuum" from use to abuse of addictive substances. Recently, it has been suggested that common neural systems may be activated by natural and pharmacological stimuli, raising the hypotheses that binge-eating disorders could be considered as addictive behaviors. The second goal of this study is to present evidences in order to highlight a possible psycho-bio-physiological superimposition between drug and "food addiction". Finally, interesting questions are brought up starting from last findings about a theoretical/psycho-bio-physiological superimposition between drug and "food addiction" and their possibly same transitionality along the same "temporal continuum" from use to abuse of addictive substances in order to investigate new therapeutic strategies based on new therapeutic strategies based on the individual moments characterizing the transition from the voluntary intake of substances to the maladaptive addictive behavior.

    Irritant and cytotoxic potentiality of six coumarins, isolated for the first time from the roots of Angelica glauca identified as 5,6,7-trimethoxycoumarin, 6-methoxy-7,8-methylenedioxycoumarin, bergapten, decursinol angelate, decursin, and nodakenetin, were investigated. The irritant potential was explored by open mouse ear assay, evaluating their ID(50) after acute and by IU (Irritant units) after chronic effects, while the cytotoxic capability was explored by their LC(50), using brine shrimp (Artemia salina) larvae (nauplii). All the coumarins exhibited well-defined irritancy on mouse's ears, compared with the positive controlled euphorbium reaction and cytotoxic response against brine shrimp larvae, compared with the positive control colchicine. Decursinol angelate and decursin were the most potent and persistent irritant compounds with least ID(50), whose reactions lasted for 48 h. 6-Methoxy-7,8-methylenedioxycoumarin and bergaten revealed an intermediate irritant reactions, while 5,6,7-trimethoxycoumarin and nodakenetin displayed the least irritant and least persistent reactions on mouse ears. Both decursin and decursinol angelate also appeared to be the stronger cytotoxic agents than other coumarins. 5,6,7-trimethoxycoumarin displayed an intermediate cytotoxic behaviour, while other three coumarins, i.e., 6-methoxy-7,8-methylenedioxycoumarin, bergapten, and nodakenetin, exhibited the least cytotoxic capacity against brine shrimp larvae.

    The purpose of this study was to determine whether the 80 items on the Interest Checklist empirically cluster into the five categories of interests described by Matsutsuyu, the developer of the tool. The Interest Checklist was administered to 367 subjects classified in three subgroups: students, working adults, and retired elderly persons. An 80-item correlation matrix was formed from the responses to the Interest Checklist for each subgroup and then used in a factor analysis model to identify the underlying structure or domains of interest. Results indicated that the Social Recreation theoretical category was empirically independent for all three subgroups; the Physical Sports and Cultural/Educational theoretical categories were empirically independent for only the college students and working adults; and the Manual Skills theoretical category was empirically independent for only the working adults. Although therapists should continue to be cautious in their interpretation of patients' Interest Checklist scores, the tool is useful for identifying patients' interests in order to choose meaningful activities for therapy.

    A checklist is an effective implementation tool, but addressing barriers that might impact on the effectiveness of its use is crucial. In this paper, we explore barriers to the uptake of an antibiotic checklist that aims to improve antibiotic use in daily hospital care. We performed an online questionnaire survey among medical specialists and residents with various professional backgrounds from nine Dutch hospitals. The questionnaire consisted of 23 statements on anticipated barriers hindering the uptake of the checklist. Furthermore, it gave the possibility to add comments. We included 219 completed questionnaires (122 medical specialists and 97 residents) in our descriptive analysis. The top six anticipated barriers included: (1) lack of expectation of improvement of antibiotic use, (2) lack of expected patients' satisfaction by checklist use, (3) lack of feasibility of the checklist, (4) negative previous experiences with other checklists, (5) the complexity of the antibiotic checklist and (6) lack of nurses' expectation of checklist use. Remarkably, 553 comments were made, mostly (436) about the content of the checklist. These insights can be used to improve the specific content of the checklist and to develop an implementation strategy that addresses the identified barriers.

  15. Interaction of reinforcement schedules, a behavioral prosthesis, and work-related behavior in adults with mental retardation.

    2005-01-01

    The effects of variable-interval (VI) and fixed-ratio (FR) schedules of reinforcement for work-related behavior and an organizer for the work materials (behavioral prosthesis) were evaluated with 3 adults with severe or profound mental retardation. The participants had been recommended for study because of high rates of off-task and aberrant behavior in their daily vocational training programs. For 2 participants, VI and FR schedules resulted in the same outcome: more aberrant behavior than on-task and off-task behavior combined. The FR schedule nearly eliminated emission of aberrant and off-task behavior by the 3rd participant. Combining the behavioral prosthesis with FR reinforcement (FR+O) increased the proportion of time spent in on-task behavior by all participants under certain FR schedule parameters. Second-by-second analyses of the observation records revealed that FR schedules reduced off-task and aberrant behavior during work sequences (i.e., ratio runs), and FR+O led to a further reduction of these behaviors during postreinforcement pauses. Overall, the results show how organizer and schedule parameters can be adjusted to produce an optimized balance between productivity and reinforcement while undesirable behavior is minimized.

    BACKGROUND Tuberous sclerosis complex is a multisystem genetic disorder with a range of physical manifestations that require evaluation, surveillance, and management. Individuals with tuberous sclerosis complex also have a range of behavioral, psychiatric, intellectual, academic, neuropsychologic, and psychosocial difficulties. These may represent the greatest burden of the disease. Around 90% of individuals with tuberous sclerosis complex will have some of these difficulties during their lifetime, yet only about 20% ever receive evaluation and treatment. The Neuropsychiatry Panel at the 2012 Tuberous Sclerosis Complex International Consensus Conference expressed concern about the significant “treatment gap” and about confusion regarding terminology relating to the biopsychosocial difficulties associated with tuberous sclerosis complex. METHODS The Tuberous Sclerosis Complex Neuropsychiatry Panel coined the term TAND—tuberous sclerosis complex-associated neuropsychiatric disorders—to bring together these multidimensional manifestations of the disorder, and recommended annual screening for TAND. In addition, the Panel agreed to develop a TAND Checklist as a guide for screening. RESULTS Here, we present an outline of the conceptualization of TAND, rationale for the structure of the TAND Checklist, and include the full US English version of the TAND Checklist. CONCLUSION We hope that the unified term TAND and the TAND Checklist will raise awareness of the importance of tuberous sclerosis complex-associated neuropsychiatric disorders and of the major burden of disease associated with it, provide a shared language and a simple tool to describe and evaluate the different levels of TAND, alert clinical teams and families or individuals of the importance of screening, assessment, and treatment of TAND, and provide a shared framework for future studies of tuberous sclerosis complex-associated neuropsychiatric disorders.

    The anterior cingulate cortex (ACC), orbitofrontal cortex (OFC), and basal ganglia have been implicated in pathological aggression. This study aimed at identifying neuroanatomical correlates of impulsive aggression in healthy children. Data from 193 representative 6- to 18-year-old healthy children were obtained from the National Institutes of Health Magnetic Resonance Imaging Study of Normal Brain Development after a blinded quality control. Cortical thickness and subcortical volumes were obtained with automated software. Aggression levels were measured with the Aggressive Behavior scale (AGG) of the Child Behavior Checklist. AGG scores were regressed against cortical thickness and basal ganglia volumes using first- and second-order linear models while controlling for age, gender, scanner site, and total brain volume. Gender by AGG interactions were analyzed. There were positive associations between bilateral striatal volumes and AGG scores (right: r = .238, p = .001; left: r = .188, p = .01). A significant association was found with right ACC and subgenual ACC cortical thickness in a second-order linear model (p < .05, corrected). High AGG scores were associated with a relatively thin right ACC cortex. An AGG by gender interaction trend was found in bilateral OFC and ACC associations with AGG scores. This study shows the existence of relationships between impulsive aggression in healthy children and the structure of the striatum and right ACC. It also suggests the existence of gender-specific patterns of association in OFC/ACC gray matter. These results may guide research on oppositional-defiant and conduct disorders.

    The purpose of this study was to test the applicability of a standardised procedure for assessing Icelandic children's behaviour/emotional problems and competencies, and to identify differences related to demographic variables. This study focuses upon the method of using the Child Behavior Checklist (CBCL) by Achenbach to estimate the reported prevalence of parents and adolescents of emotional and behaviour problems in children from 2-16 years of age and self-reported prevalence of adolescents from 11-18 years, selected at random from the general population, both in urban and rural areas. The information was obtained by mailing checklists with a letter to parents of children 2-10 years of age. The checklists for adolescents 11-18 years of age were distributed by teachers in school. Those adolescents who were not in school received the checklists by mail at their homes. The Child Behavior Checklists used for analyses were completed by 109 parents of 2-3 year old children; 943 parents of 4-16 year old children, and 545 non-referred adolescents from the general population. The rate of response was lowest for the youngest age group 47%, but increased to 62% with increasing age of the child. The response rate among the adolescents answering the Youth Self Report was 64%. Comparisons with the Child Behavior Checklists from this study are presented with Dutch, American, French, Canadian, German and Chilean samples and show striking similarities in four of these countries on the behaviour/emotional problems reported.

    2009-01-01

    Checklists are common tools used in many industries. Unfortunately, their adoption in the field of medicine has been limited to equipment operations or part of specific algorithms. Yet they have tremendous potential to improve patient outcomes by democratizing knowledge and helping ensure that all patients receive evidence-based best practices and safe high-quality care. Checklist adoption has been slowed by a variety of factors, including provider resistance, delays in knowledge dissemination and integration, limited methodology to guide development and maintenance, and lack of effective technical strategies to make them available and easy to use. In this article, we explore some of the principles and possible strategies to further develop and encourage the implementation of checklists into medical practice. We describe different types of checklists using examples and explore the benefits they offer to improve care. We suggest methods to create checklists and offer suggestions for how we might apply them, using some examples from our own experience, and finally, offer some possible directions for future research.

    Efforts to replace the rabbit skin irritation test have been underway for many years, encouraged by the EU Cosmetics Directive and REACH. Recently various in vitro tests have been developed, evaluated and validated. A key difficulty in confirming the validity of in vitro methods is that animal data are scarce and of limited utility for prediction of human effects, which adversely impacts their acceptance. This study examines whether in vivo or in vitro data most accurately predicted human effects. Using the 4-hr human patch test (HPT) we examined a number of chemicals whose EU classification of skin irritancy is known to be borderline, or where in vitro methods provided conflicting results. Of the 16 chemicals classified as irritants in the rabbit, only five substances were found to be significantly irritating to human skin. Concordance of the rabbit test with the 4-hr HPT was only 56%, whereas concordance of human epidermis models with human data was 76% (EpiDerm) and 70% (EPISKIN). The results confirm observations that rabbits overpredict skin effects in humans. Therefore, when validating in vitro methods, all available information, including human data, should be taken into account before making conclusions about their predictive capacity.

    This edition of the checklist includes 446 species, of which 407 are on the Regular Species List, 8 on the Provisional, and 31 on the Hypothetical. This new publication has been greatly expanded and much revised over the previous checklist (GOS Occasional Publ. No. 10, 1986, 48 pp., 6x9 inches) to a 7x10-inch format with an extensive Literature Cited section added, 22 species added to the Regular List, 2 to the Provisional List, and 9 to the Hypothetical List. Each species account is much more comprehensive over all previous editions of the checklist. Among some of the new features are citations for sources of most information used, high counts of individuals for each species on the Regular List, extreme dates of occurrence within physiographic regions, a list of abbreviations and acronyms, and for each species the highest form of verifiable documentation given with its repository institution with a catalog number. This checklist is helpful for anyone working with birds in the Southeastern United States or birding in that region. Sykes' contribution to this fifth edition of the Annotated Checklist of Georgia Birds includes: suggestion of the large format and spiral binding, use of Richard A. Parks' painting of the Barn Owl on the front cover, use of literature citations throughout, and inclusion of high counts for each species. Sykes helped plan all phases of the publication, wrote about 90% of the Introduction and 84 species accounts (Osprey through Red Phalarope), designed the four maps in the introduction section and format for the Literature Cited, and with Giff Beaton designed the layout of the title page.

    Functional abdominal pain and irritable bowel syndrome are two prevalent disorders in childhood which are associated with recurrent or chronic abdominal pain, disabilities in daily functioning, and reduced quality of life. This study aimed to evaluate a brief hypnotherapeutic-behavioral intervention program in a prospective randomized controlled design. Thirty-eight children, 6 to 12 years of age, and their parents were randomly assigned to a standardized hypnotherapeutic-behavioral treatment (n = 20) or to a waiting list condition (n = 18). Both groups were reassessed 3 months after beginning. Primary outcome variables were child-completed pain measures and pain-related disability. Secondary outcome variables were parent-completed measures of their children's pain and pain-related disability. Health-related quality of life from both perspectives also served as a secondary outcome. In the treatment group, 11 of 20 children (55.0%) showed clinical remission (>80% improvement), whereas only one child (5.6%) in the waiting list condition was classified as responder. Children in the treatment group reported a significantly greater reduction of pain scores and pain-related disability than children of the waiting list condition. Parental ratings also showed a greater reduction of children's abdominal pain and pain-related disability. Health-related quality of life did not increase significantly. Hypnotherapeutic and behavioral interventions are effective in treating children with long-standing AP. Treatment success of this brief program should be further evaluated against active interventions with a longer follow-up.

  6. The impact of intolerance of uncertainty, worry and irritability on quality of life in persons with epilepsy: irritability as mediator.

    Epilepsy is a neurological disorder afflicting many people in the world. The impact of epilepsy on the quality of life of those afflicted with epilepsy is greater than the limitations imposed by the seizures alone. Among the several psychological disorders found to be comorbid with epilepsy are anxiety and depression, both of which impair quality of life in epilepsy. Some studies have reported that the anxiety seen in epilepsy is characterized by worry while the depression seen is characterized by irritability. A concept common to both anxiety and depression is intolerance of uncertainty. Therefore, the study explores the relationship between intolerance of uncertainty, worry and irritability and their association to quality of life in epilepsy. A descriptive-correlational research method was used and the research sample comprised 60 consecutive referrals seeking outpatient neurological services for epilepsy at Alavi Hospital in Ardebil. Data were collected by administering the Penn State Worry Questionnaire, Intolerance of Uncertainty Scale, Irritability Questionnaire and Quality of Life in Epilepsy Inventory. Data were analyzed using Pearson's correlation coefficients and multivariate regression analysis. Mediation and moderation analyses were conducted. Findings indicated that intolerance of uncertainty, worry and irritability have unique significant effects on quality of life. The implications are that interventions aimed at improving the quality of life of patients with epilepsy should address their feelings of uncertainty, worry and irritability. Furthermore, irritability seems to mediate the impact of both intolerance of uncertainty and worry on quality of life of individuals with epilepsy. No significant moderation effects were noted. Results underscore the important role of irritability in the quality of life of persons with epilepsy. The findings are discussed with reference to the possibility of particular predisposing temperaments and add credence to

    To evaluate the contribution of fixational eye movements to dynamic aberration, 50 healthy eyes were examined with an original custom-built Shack-Hartmann aberrometer, running at a temporal frequency of 236Hz, with 22 lenslets across a 5mm pupil, synchronized with a 236Hz pupil tracker. A comparison of the dynamic behavior of the first 21 Zernike modes (starting from defocus) with and without digital pupil stabilization, on a 3.4s sequence between blinks, showed that the contribution of fixational eye movements to dynamic aberration is negligible. Therefore we highlighted the fact that a pupil tracker coupled to an Adaptive Optics Ophthalmoscope is not essential to achieve diffraction-limited resolution.

    This is a checklist of actions for healthcare, public health, nongovernmental organizations, and private entities to use to strengthen the resilience of their community's health sector to disasters. It is informed by the experience of Hurricane Sandy in New York and New Jersey and analyzed in the context of findings from other recent natural disasters in the United States. The health sector is defined very broadly, including-in addition to hospitals, emergency medical services (EMS), and public health agencies-healthcare providers, outpatient clinics, long-term care facilities, home health providers, behavioral health providers, and correctional health services. It also includes community-based organizations that support these entities and represent patients.

    This is a checklist of actions for healthcare, public health, nongovernmental organizations, and private entities to use to strengthen the resilience of their community’s health sector to disasters. It is informed by the experience of Hurricane Sandy in New York and New Jersey and analyzed in the context of findings from other recent natural disasters in the United States. The health sector is defined very broadly, including—in addition to hospitals, emergency medical services (EMS), and public health agencies—healthcare providers, outpatient clinics, long-term care facilities, home health providers, behavioral health providers, and correctional health services. It also includes community-based organizations that support these entities and represent patients.

    2017-11-01

    In this communication, we propose a novel method for estimating the aberrations of a space telescope from phase diversity data. The images recorded by such a telescope can be degraded by optical aberrations due to design, fabrication or misalignments. Phase diversity is a technique that allows the estimation of aberrations. The only estimator found in the relevant literature is based on a joint estimation of the aberrated phase and the observed object. We recall this approach and study the behavior of this joint estimator by means of simulations. We propose a novel marginal estimator of the sole phase. it is obtained by integrating the observed object out of the problem; indeed, this object is a nuisance parameter in our problem. This reduces drastically the number of unknown and provides better asymptotic properties. This estimator is implemented and its properties are validated by simulation. its performance is equal or even better than that of the joint estimator for the same computing cost.

    The benefit of utilizing surgical safety checklists has been recently questioned. We evaluated our checklist performance after implementing a program that includes checklist-related good catches. Multifaceted interventions aimed at the preincision checklist and 5 prospective audits were conducted from 2011-2015. We documented adherence to the checklist (verbalization of each checkpoint), fidelity (meaningful performance of each checkpoint), and good catches (events with the potential to cause the patient harm but that were prevented from occurring). Good catches were divided into quality improvement-based categories (processes, medication, safety, communication, and equipment). A total of 1,346 checklist performances were observed (range, 144-373/yr). Adherence to the preincision checklist improved from 30% to 95% (P < .001), while adherence to the preinduction and debriefing checklists decreased (71% to 56%, P = .002) and remained unchanged (76%), respectively. Preincision fidelity decreased from 86% to 76% (P = .012). Good catches were identified during 16% of preincision checklist performances; process issues were most common (32%) followed by issues of medication administration (30%) and safety (22%). Implementation of a systematic checklist program resulted in significant and sustainable improvement in performance. Meaningful use and associated good catches may be more appropriate metric than actual patient harm for measuring checklist effectiveness. Although not previously described, checklist-related good catches represent an unknown benefit of checklists. Copyright © 2016 Elsevier Inc. All rights reserved.

    The importance of dimensional approaches is widely recognized, but an empirical base for clinical application is lacking. This is particularly true for irritability, a dimensional phenotype that cuts across many areas of psychopathology and manifests early in life. We examine longitudinal, dimensional patterns of irritability and their clinical import in early childhood. Irritability was assessed longitudinally over an average of 16 months in a clinically enriched, diverse community sample of preschoolers (N = 497; mean = 4.2 years; SD = 0.8). Using the Temper Loss scale of the Multidimensional Assessment Profile of Disruptive Behavior (MAP-DB) as a developmentally sensitive indicator of early childhood irritability, we examined its convergent/divergent, clinical, and incremental predictive validity, and modeled its linear and nonlinear associations with clinical risk. The Temper Loss scale demonstrated convergent and divergent validity to child and maternal factors. In multivariate analyses, Temper Loss predicted mood (separation anxiety disorder [SAD], generalized anxiety disorder [GAD], and depression/dysthymia), disruptive (oppositional defiant disorder [ODD], attention-deficit/hyperactivity disorder [ADHD], and conduct disorder [CD]) symptoms. Preschoolers with even mildly elevated Temper Loss scale scores showed substantially increased risk of symptoms and disorders. For ODD, GAD, SAD, and depression, increases in Temper Loss scale scores at the higher end of the dimension had a greater impact on symptoms relative to increases at the lower end. Temper Loss scale scores also showed incremental validity over DSM-IV disorders in predicting subsequent impairment. Finally, accounting for the substantial heterogeneity in longitudinal patterns of Temper Loss significantly improved prediction of mood and disruptive symptoms. Dimensional, longitudinal characterization of irritability informs clinical prediction. A vital next step will be empirically generating

    Previous studies have demonstrated contact irritant and spatial repellent behaviors in Aedes aegypti following exposure to sublethal concentrations of chemicals. These sublethal actions are currently being evaluated in the development of a push-pull strategy for Ae. aegypti control. This study reports on mosquito escape responses after exposure to candidate chemicals for a contact irritant focused push-pull strategy using varying concentrations and focal application. Contact irritancy (escape) behavior, knockdown and 24 hour mortality rates were quantified in populations of female Ae. aegypti under laboratory conditions and validated in the field (Thailand and Peru) using experimental huts. Evaluations were conducted using varying concentrations and treatment surface area coverage (SAC) of three pyrethroid insecticides: alphacypermethrin, lambacyhalothrin and deltamethrin. Under laboratory conditions, exposure of Ae. aegypti to alphacypermethrin using the standard field application rate (FAR) resulted in escape responses at 25% and 50% SAC that were comparable with escape responses at 100% SAC. Significant escape responses were also observed at <100% SAC using ½FAR of all test compounds. In most trials, KD and 24 hour mortality rates were higher in mosquitoes that did not escape than in those that escaped. In Thailand, field validation studies indicated an early time of exit (by four hours) and 40% increase in escape using ½FAR of alphacypermethrin at 75% SAC compared to a matched chemical-free control. In Peru, however, the maximum increase in Ae. aegypti escape from alphacypermethrin-treated huts was 11%. Results presented here suggest a potential role for sublethal and focal application of contact irritant chemicals in an Ae. aegypti push-pull strategy to reduce human-vector contact inside treated homes. However, the impact of an increase in escape response on dengue virus transmission is currently unknown and will depend on rate of biting on human hosts prior

    The primary purpose of the present study was to investigate the mechanism of the counter-irritating activity of topical iodine against skin lesions induced by chemical and thermal stimuli. The hypothesis that iodine exerts its activity by inducing an endogenous anti-inflammatory factor was confirmed by exposing guinea pig skin to heat stimulus followed by topical iodine treatment and skin extraction. Injection of the extract into naive guinea pigs reduced heat-induced irritation by 69%. The protective factor, identified as a new nonapeptide (histone H2A 36-44, H-Lys-Gly-Asn-Tyr-Ala-Glu-Arg-Ileu-Ala-OH), caused reduction of 40% in irritation score in heat-exposed guinea pigs. The murine analog (H-Lys-Gly-His-Tyr-Ala-Glu-Arg-Val-Gly-OH, termedmore » IIIM1) reduced sulfur mustard (SM)-induced ear swelling at a dose-dependent bell-shape manner reaching peak activity of 1 mg/kg. Cultured keratinocytes transfected with the peptide were more resistant towards SM than the control cells. The peptide suppressed oxidative burst in activated neutrophils in a concentration-dependent manner. In addition, the peptide reduced glucose oxidase-induced skin edema in mice at a dose-dependent bell-shape manner. Apart from thermal and chemical-induced skin irritation this novel peptide might be of potential use in chronic dermal disorders such as psoriasis and pemphigus as well as non-dermal inflammatory diseases like multiple sclerosis, arthritis and colitis.« less

    An updated checklist of 235 mosquito species from Madagascar is presented. The number of species has increased considerably compared to previous checklists, particularly the last published in 2003 (178 species). This annotated checklist provides concise information on endemism, taxonomic position, developmental stages, larval habitats, distribution, behavior, and vector-borne diseases potentially transmitted. The 235 species belong to 14 genera: Aedeomyia (3 species), Aedes (35 species), Anopheles (26 species), Coquillettidia (3 species), Culex (at least 50 species), Eretmapodites (4 species), Ficalbia (2 species), Hodgesia (at least one species), Lutzia (one species), Mansonia (2 species), Mimomyia (22 species), Orthopodomyia (8 species), Toxorhynchites (6 species), and Uranotaenia (73 species). Due to non-deciphered species complexes, several species remain undescribed. The main remarkable characteristic of Malagasy mosquito fauna is the high biodiversity with 138 endemic species (59%). Presence and abundance of species, and their association, in a given location could be a bio-indicator of environmental particularities such as urban, rural, forested, deforested, and mountainous habitats. Finally, taking into account that Malagasy culicidian fauna includes 64 species (27%) with a known medical or veterinary interest in the world, knowledge of their biology and host preference summarized in this paper improves understanding of their involvement in pathogen transmission in Madagascar. © M.L.

  17. Attention checklist: a rating scale for mildly mentally handicapped adolescents.

    A check list for attentional deficits without reference to hyperactive behavior observed in the classroom was constructed, and teachers' ratings were factor analyzed. The check-list rating was compared to a widely used rating scale for attention deficit-hyperactive disorder (AD-HD), the Abbreviated Conners Rating Scale. Both scales were given to 15 teachers to rate 100 mildly mentally handicapped adolescent students. Analysis showed that 33% of the mentally handicapped students were rated above 1.5 on the Conners Scale, which is the cut-off for hyperactivity. This is much higher than the prevalence of hyperactivity in regular classrooms. The two sets of ratings correlated strongly (.84). Check-list items were grouped under one factor explaining 70.7% of variance and so are recommended for use in discriminating attentional deficit in mentally handicapped as well as in regular class students. The high correlation with ratings on the Conners Scale suggests that AD-HD is a unitary syndrome with attention being most problematic for children labeled hyperactive.

    Retinoids are structurally related derivatives of vitamin A and are required for normal vision as well as cell proliferation and differentiation. Clinically, retinoids are effective in treating many skin disorders and cancers. Application of retinoids evokes substantial irritating side effects, including pain and inflammation; however, the precise mechanisms accounting for the sensory hypersensitivity are not understood. Here we show that both naturally occurring and synthetic retinoids activate recombinant or native transient receptor potential channel vanilloid subtype 1 (TRPV1), an irritant receptor for capsaicin, the pungent ingredient of chili peppers. In vivo, retinoids produced pain-related behaviors that were either eliminated or significantly reduced by genetic or pharmacological inhibition of TRPV1 function. These findings identify TRPV1 as an ionotropic receptor for retinoids and provide cellular and molecular insights into retinoid-evoked hypersensitivity. These findings also suggest that selective TRPV1 antagonists are potential therapeutic drugs for treating retinoid-induced sensory hypersensitivity. PMID:23925292

    We estimated aberrations using Zernike sensitivity analysis. We found the difference of the tolerated aberration with line direction for illumination. The tolerated aberration of perpendicular line for illumination is much smaller than that of parallel line. We consider this difference to be attributable to the mask 3D effect. We call it mask-induced aberration. In the case of the perpendicular line for illumination, there was a difference in CD between right line and left line without aberration. In this report, we discuss the possibility of pattern formation in NA 0.25 generation EUV lithography tool. In perpendicular pattern for EUV light, the dominant part of aberration is mask-induced aberration. In EUV lithography, pattern correction based on the mask topography effect will be more important.

    The development of family-based programs for child weight management requires an understanding of parents' difficulties in managing children's eating and physical activity behaviors; however, knowledge about the specific behaviors that parents find most difficult to address is still limited. The Lifestyle Behavior Checklist (LBC) is an Australian instrument that assesses parents' perceptions of children's obesity-related behaviors (the Problem scale), and parents' self-efficacy in dealing with these behaviors (the Confidence scale). Our aims were 1) to examine the psychometric properties (the factor structure, internal reliability, construct and discriminative validity) of the LBC in parents of preschoolers in Sweden, using the Child Feeding Questionnaire (CFQ) as a criterion measure, 2) to study associations between the LBC and socio-demographic factors. The LBC and the CFQ (measuring parental feeding practices) were distributed to parents from 25 schools/preschools and to parents starting a childhood obesity intervention. To test the fit of the original four-factor model (misbehavior in relation to food, overeating, emotional correlates of being overweight, physical activity (24 items)) to the data, confirmatory factor analysis (CFA) was performed. Structural equation modelling was used to examine associations between the LBC and the CFQ and socio-demographic factors. In a sample of 478 parents, a five-factor structure proved best fit to data, after excluding 6 items and allowing two pairs of error terms to correlate (TLI = 0.899; CFI = 0.918; RMSEA = 0.042; SRMR = 0.055). The Confidence scale indicated unidimensionality, therefore a hierarchical CFA with 5 first order factors and one second order factor was tested showing good fit. The validity of the LBC was proven by relevant associations with the CFQ and child weight status; parental responses differed depending on child weight status. The Confidence scale was not associated with any child or

    AIM To describe the development and implementation of a person-centered endoscopy safety checklist and to evaluate the effects of a “checklist intervention”. METHODS The checklist, based on previously published safety checklists, was developed and locally adapted, taking patient safety aspects into consideration and using a person-centered approach. This novel checklist was introduced to the staff of an endoscopy unit at a Stockholm University Hospital during half-day seminars and team training sessions. Structured observations of the endoscopy team’s performance were conducted before and after the introduction of the checklist. In addition, questionnaires focusing on patient participation, collaboration climate, and patient safety issues were collected from patients and staff. RESULTS A person-centered safety checklist was developed and introduced by a multi-professional group in the endoscopy unit. A statistically significant increase in accurate patient identity verification by the physicians was noted (from 0% at baseline to 87% after 10 mo, P < 0.001), and remained high among nurses (93% at baseline vs 96% after 10 mo, P = nonsignificant). Observations indicated that the professional staff made frequent attempts to use the checklist, but compliance was suboptimal: All items in the observed nurse-led “summaries” were included in 56% of these interactions, and physicians participated by directly facing the patient in 50% of the interactions. On the questionnaires administered to the staff, items regarding collaboration and the importance of patient participation were rated more highly after the introduction of the checklist, but this did not result in statistical significance (P = 0.07/P = 0.08). The patients rated almost all items as very high both before and after the introduction of the checklist; hence, no statistical difference was noted. CONCLUSION The intervention led to increased patient identity verification by physicians - a patient safety

    Oxidation hair-dyes, which are the principal hair-dyes, sometimes induce painful sensory irritation of the scalp caused by the combination of highly reactive substances, such as hydrogen peroxide and alkali agents. Although many cases of severe facial and scalp dermatitis have been reported following the use of hair-dyes, sensory irritation caused by contact of the hair-dye with the skin has not been reported clearly. In this study, we used a self-assessment questionnaire to measure the sensory irritation in various regions of the body caused by two model hair-dye bases that contained different amounts of alkali agents without dyes. Moreover, the occipital region was found as an alternative region of the scalp to test for sensory irritation of the hair-dye bases. We used this region to evaluate the relationship of sensitivity with skin properties, such as trans-epidermal water loss (TEWL), stratum corneum water content, sebum amount, surface temperature, current perception threshold (CPT), catalase activities in tape-stripped skin and sensory irritation score with the model hair-dye bases. The hair-dye sensitive group showed higher TEWL, a lower sebum amount, a lower surface temperature and higher catalase activity than the insensitive group, and was similar to that of damaged skin. These results suggest that sensory irritation caused by hair-dye could occur easily on the damaged dry scalp, as that caused by skin cosmetics reported previously.

    To investigate the role of psychiatric history and psychologic adjustment on aberrant drug-related behavior among patients prescribed opioids for noncancer pain. Two hundred twenty-eight patients prescribed opioids for chronic pain were classified as either high or low on psychiatric morbidity on the basis of their responses on the psychiatric subscale of the Prescription Drug Use Questionnaire (PDUQ). They also completed the Brief Pain Inventory (BPI), Screener and Opioid Assessment for Pain Patients (SOAPP), and the Current Medication Misuse Measure (COMM). Patients were followed for 5 months and submitted a urine toxicology screen, and their treating physician completed the Prescription Opioid Therapy Questionnaire (POTQ). On the basis of the results from the SOAPP, COMM, POTQ, and urine screens, patients were classified as positive or negative on the Drug Misuse Index (DMI). One hundred and three (N=103) of the patients (45%) were classified in the low psychiatric group (Low Psych) whereas 55% (N=125) were classified in the high psychiatric morbidity group (High Psych). High Psych patients were significantly younger than Low Psych patients and had been taking opioids longer (P<0.05). The High Psych group showed significantly higher SOAPP and COMM scores than the Low Psych patients (P<0.001), had a greater frequency of abnormal urine toxicology screens (P<0.01), and significantly higher scores on the DMI (P<0.001). A consistent association was found between psychiatric morbidity and prescription opioid misuse in chronic pain patients. Psychiatric factors, such as a history of mood disorder, psychologic problems, and psychosocial stressors, may place patients at risk for misuse of prescription opioids. Future studies to elucidate the risk of medication misuse and aberrant drug behavior among this patient population are needed.

    Turbuhaler and Diskus are commonly used powder inhaler devices for patients with respiratory disease. Their effectiveness is limited in part by a patient's ability to use them correctly. This has led to numerous studies being conducted over the last decade to assess the correct use of these devices by patients and health care professionals. These studies have generally used device-specific checklists to assess technique, this being the most feasible and accessible method for assessment. However, divergence between the checklists and scoring systems for the same device in different studies makes direct comparison of results difficult and at times inappropriate. Little evidence is available to assess the relative importance of different criteria; however, brief patient training based on specific inhaler technique checklists leads to significant improvement in asthma outcomes. This paper reviews common checklists and scoring systems used for Turbuhaler and Diskus, discusses the problem of heterogeneity between different checklists, and finally recommends suitable checklists and scoring systems for these devices based on the literature and previous findings. Only when similar checklists are used across different research studies will accurate comparisons and meta-analysis be possible. Copyright © 2014 by Daedalus Enterprises.

    Few treatments have been able to effectively manage pediatric irritable bowel syndrome (IBS). Internet-delivered cognitive behavior therapy (Internet-CBT) based on exposure for abdominal symptoms is effective for adult IBS. The objective of this study was to evaluate the efficacy of Internet-CBT based on behavioral exposure for adolescents with IBS. Adolescents with IBS fulfilling the Rome III criteria were randomized to either Internet-CBT or a wait-list control. The Internet-CBT was a 10-week intervention where the main component was exposure to IBS symptoms by reduction of avoidance of abdominal symptoms and instead stepwise provocation of symptoms. The primary outcome was total score on Gastrointestinal Symptoms Rating Scale for IBS (GSRS-IBS). Secondary outcomes included adolescent- and parent-rated quality of life and parent-rated gastrointestinal symptoms. Difference between groups was assessed from pretreatment to posttreatment and the Internet-CBT group was also evaluated at 6 months after treatment completion. A total of 101 adolescents with IBS (13-17 years of age) were included in this study. Dropout rates were low (6%) and all randomized patients were included in intent-to-treat analyses based on mixed effects models. Analyses showed a significant larger pretreatment to posttreatment change on the primary outcome GSRS-IBS (B=-6.42, P=0.006, effect size Cohen's d=0.45, 95% confidence interval (0.12, 0.77)) and on almost all secondary outcomes for the Internet-CBT group compared with the control group. After 6 months, the results were stable or significantly improved. Internet-CBT based on exposure exercises for adolescents with IBS can effectively improve gastrointestinal symptoms and quality of life.

  9. Camera processing with chromatic aberration.

    Korneliussen, Jan Tore; Hirakawa, Keigo

    2014-10-01

    Since the refractive index of materials commonly used for lens depends on the wavelengths of light, practical camera optics fail to converge light to a single point on an image plane. Known as chromatic aberration, this phenomenon distorts image details by introducing magnification error, defocus blur, and color fringes. Though achromatic and apochromatic lens designs reduce chromatic aberration to a degree, they are complex and expensive and they do not offer a perfect correction. In this paper, we propose a new postcapture processing scheme designed to overcome these problems computationally. Specifically, the proposed solution is comprised of chromatic aberration-tolerant demosaicking algorithm and post-demosaicking chromatic aberration correction. Experiments with simulated and real sensor data verify that the chromatic aberration is effectively corrected.

    2018-03-01

    Nurses working at general hospitals face difficulties in providing dementia care. The current study examined aged care nurses' dementia care practices in the hospital setting and developed a dementia care checklist that nurses can use to review their own care practice. A self-administered questionnaire was given to 676 participants; responses were collected from 595 participants. Exploratory factor analysis identified six factors (e.g., patient understanding prompted by concern and interest for the patient, respect for patients' voluntary behavior, early detection of abnormalities) among the questionnaire's 28 items. This analysis provided a framework for the checklist and verified that it had satisfactory internal consistency and construct validity. The frequency of care practices varied with participants' knowledge of dementia care requirements, satisfaction with their own dementia care practice, confidence in their ability to judge patients' physical condition, and cooperation with colleagues. This checklist might improve dementia care in hospital settings. [Res Gerontol Nurs. 2018; 11(2):91-102.]. © 2018 Ikegami and Ota.

Materials studied were N-methylethanolamine (MEA), N, N, -dimethylethanolamine (DMEA), N, N, -dimethylisopropanolamine (DMIPA), N-methyldiethanolamine (MDEA), and tertbutyldiethanolamine (BDEA). All these alkylalkanolamines were of comparable acute peroral toxicity in the rat (LD50 range 1.48-2.83 ml/kg). By 24 h occluded epicutaneous contact in the rabbit, MEA, DMEA and DMIPA were of moderate acute percutaneous toxicity (LD50 range 1.13-2.0 ml/kg), MDEA was of slight acute percutaneous toxicity (LD50 male 9.85 ml/kg, female 10.90 ml/kg), and BDEA of intermediate toxicity (LD50 6.4 ml/kg). Due to differences in vapor pressure the acute vapor exposure toxicity of the alkylalkanolamines to rats varied; MEA, MDEA and BDEA were of a low order of acute toxicity, and DMIPA was moderately toxic with an LT50 of 3.2 h for a saturated vapor atmosphere exposure. A 4 h-LC50 (rat combined sex) of 1461 ppm was determined for DMEA. All alkylalkanolamines studied, except MDEA, were moderately to markedly irritating and caused variable degrees of skin corrosivity; MDEA caused only transient minor skin irritation. In accord with the skin irritancy results, the eye irritancy from 0.005 ml MEA, DMEA, DMIPA and BDEA was severe, and that from MDEA was slight. Exposure to these compounds has implications for occupational health procedures.

    Interventional radiology (IR) is an invasive speciality with the potential for complications as with other invasive specialities. The World Health Organization (WHO) produced a surgical safety checklist to decrease the morbidity and mortality associated with surgery. The Cardiovascular and Interventional Society of Europe (CIRSE) set up a task force to produce a checklist for IR. Use of the checklist will, we hope, reduce the incidence of complications after IR procedures. It has been modified from the WHO surgical safety checklist and the RAD PASS from Holland.

    The goal of this study is to examine the developmental epidemiology of normative irritability and its tonic and phasic components in a longitudinal community sample of youth. Eight waves of data from the prospective, community Great Smoky Mountains Study (6,674 assessments of 1,420 participants) were used, covering children in the community 9 to 16 years of age. Youth and 1 parent were interviewed using the Child and Adolescent Psychiatric Assessment to assess tonic (touchy/easily annoyed, irritable mood, angry or resentful) and phasic (temper tantrums or anger outbursts) components of irritability, including frequency, duration, onset, and cross-context variability. At any given point in childhood/adolescence, 51.4% (standard error [SE] = 1.4) of participants reported phasic irritability, 28.3% (SE = 1.2) reported tonic irritability, and 22.8% (SE = 1.1) reported both. These prevalence levels decreased with age but did not vary by sex. The overlap between tonic and phasic irritability was high (odds ratio = 5.8, 95% CI = 3.3-10.5, p < .0001), with little evidence of tonic occurring without phasic irritability. Both tonic and phasic irritability predicted one another over time, supporting both heterotypic and homotypic continuity. Low levels of either tonic or phasic irritability increased risk for disrupted functioning including service use, school suspensions, parental burden, and emotional symptoms both concurrently and at 1-year follow-up. Irritability is relatively common, decreases with age but does not vary by sex, and at almost any level is associated with increased risk of disrupted functioning. Its relative components frequently overlap, although irritable outbursts are more common than irritable mood. Irritability appears to be a high-priority transdiagnostic marker for screening children in need of clinical attention. Copyright © 2015 American Academy of Child and Adolescent Psychiatry.

    Clinical checklists available have been developed to assess the risk of a positive Fragile X syndrome but they include relatively small sample sizes. Therefore, we carried out a meta-analysis that included statistical pooling of study results to obtain accurate figures on the prevalence of clinical predictors of Fragile X syndrome among patients with intellectual disability, thereby helping health professionals to improve their referrals for Fragile X testing. All published studies consisting of cytogenetic and/or molecular screening for fragile X syndrome among patients with intellectual disability, were eligible for the meta-analysis. All patients enrolled in clinical checklists trials of Fragile X syndrome were eligible for this review, with no exclusion based on ethnicity or age. Odds ratio values, with 95% confidence intervals as well as Cronbach coefficient alpha, was reported to assess the frequency of clinical characteristics in subjects with intellectual disability with and without the fragile X mutation to determine the most discriminating. The following features were strongly associated with Fragile X syndrome: skin soft and velvety on the palms with redundancy of skin on the dorsum of hand [OR: 16.85 (95% CI 10.4-27.3; α:0.97)], large testes [OR: 7.14 (95% CI 5.53-9.22; α: 0.80)], large and prominent ears [OR: 18.62 (95% CI 14.38-24.1; α: 0.98)], pale blue eyes [OR: 8.97 (95% CI 4.75-16.97; α: 0.83)], family history of intellectual disability [OR: 3.43 (95% CI 2.76-4.27; α: 0.81)] as well as autistic-like behavior [OR: 3.08 (95% CI 2.48-3.83; α: 0.77)], Flat feet [OR: 11.53 (95% CI 6.79-19.56; α:0.91)], plantar crease [OR: 3.74 (95% CI 2.67-5.24; α: 0.70)]. We noted a weaker positive association between transverse palmar crease [OR: 2.68 (95% CI 1.70-4.18; α: 0.51)], elongated face [OR: 3.69 (95% CI 2.84-4.81; α: 0.63)]; hyperextensible metacarpo-phalangeal joints [OR: 2.68 (95% CI 2.15-3.34; α: 0.57)] and the Fragile X syndrome.

    The rapid evolution and adoption of mobile devices raise new usability challenges, given their limitations (in screen size, battery life, etc.) as well as the specific requirements of this new interaction. Traditional evaluation techniques need to be adapted in order for these requirements to be met. Heuristic evaluation (HE), an Inspection Method based on evaluation conducted by experts over a real system or prototype, is based on checklists which are desktop-centred and do not adequately detect mobile-specific usability issues. In this paper, we propose a compilation of heuristic evaluation checklists taken from the existing bibliography but readapted to new mobile interfaces. Selecting and rearranging these heuristic guidelines offer a tool which works well not just for evaluation but also as a best-practices checklist. The result is a comprehensive checklist which is experimentally evaluated as a design tool. This experimental evaluation involved two software engineers without any specific knowledge about usability, a group of ten users who compared the usability of a first prototype designed without our heuristics, and a second one after applying the proposed checklist. The results of this experiment show the usefulness of the proposed checklist for avoiding usability gaps even with nontrained developers. PMID:25295300

    To develop a brachytherapy audit checklist that could be used to prepare for Nuclear Regulatory Commission or agreement state inspections, to aid in readiness for a practice accreditation visit, or to be used as an annual internal audit tool. Six board-certified medical physicists and one radiation oncologist conducted a thorough review of brachytherapy-related literature and practice guidelines published by professional organizations and federal regulations. The team members worked at two facilities that are part of a large, academic health care center. Checklist items were given a score based on their judged importance. Four clinical sites performed an audit of their program using the checklist. The sites were asked to score each item based on a defined severity scale for their noncompliance, and final audit scores were tallied by summing the products of importance score and severity score for each item. The final audit checklist, which is available online, contains 83 items. The audit scores from the beta sites ranged from 17 to 71 (out of 690) and identified a total of 7-16 noncompliance items. The total time to conduct the audit ranged from 1.5 to 5 hours. A comprehensive audit checklist was developed which can be implemented by any facility that wishes to perform a program audit in support of their own brachytherapy program. The checklist is designed to allow users to identify areas of noncompliance and to prioritize how these items are addressed to minimize deviations from nationally-recognized standards.

    A Full-Field OCT (FFOCT) setup coupled to a compact transmissive liquid crystal spatial light modulator (LCSLM) is used to induce or correct aberrations and simulate eye examinations. To reduce the system complexity, strict pupil conjugation was abandoned. During our work on quantifying the effect of geometrical aberrations on FFOCT images, we found that the image resolution is almost insensitive to aberrations. Indeed if the object channel PSF is distorted, its interference with the reference channel conserves the main feature of an unperturbed PSF with only a reduction of the signal level. This unique behavior is specific to the use of a spatially incoherent illumination. Based on this, the FFOCT image intensity was used as the metric for our wavefront sensorless correction. Aberration correction was first conducted on an USAF resolution target with the LSCLM as both aberration generator and corrector. A random aberration mask was induced, and the low-order Zernike Modes were corrected sequentially according to the intensity metric function optimization. A Ficus leaf and a fixed mouse brain tissue slice were also imaged to demonstrate the correction of sample self-induced wavefront distortions. After optimization, more structured information appears for the leaf imaging. And the high-signal fiber-like myelin fiber structures were resolved much more clearly after the whole correction process for mouse brain imaging. Our experiment shows the potential of this compact AO-FFOCT system for aberration correction imaging. This preliminary approach that simulates eyes aberrations correction also opens the path to a simple implementation of FFOCT adaptive optics for retinal examinations.

  20. The Ex Vivo Eye Irritation Test as an alternative test method for serious eye damage/eye irritation.

    Ocular irritation testing is a common requirement for the classification, labelling and packaging of chemicals (substances and mixtures). The in vivo Draize rabbit eye test (OECD Test Guideline 405) is considered to be the regulatory reference method for the classification of chemicals according to their potential to induce eye injury. In the Draize test, chemicals are applied to rabbit eyes in vivo, and changes are monitored over time. If no damage is observed, the chemical is not categorised. Otherwise, the classification depends on the severity and reversibility of the damage. Alternative test methods have to be designed to match the classifications from the in vivo reference method. However, observation of damage reversibility is usually not possible in vitro. Within the present study, a new organotypic method based on rabbit corneas obtained from food production is demonstrated to close this gap. The Ex Vivo Eye Irritation Test (EVEIT) retains the full biochemical activity of the corneal epithelium, epithelial stem cells and endothelium. This permits the in-depth analysis of ocular chemical trauma beyond that achievable by using established in vitro methods. In particular, the EVEIT is the first test to permit the direct monitoring of recovery of all corneal layers after damage. To develop a prediction model for the EVEIT that is comparable to the GHS system, 37 reference chemicals were analysed. The experimental data were used to derive a three-level potency ranking of eye irritation and corrosion that best fits the GHS categorisation. In vivo data available in the literature were used for comparison. When compared with GHS classification predictions, the overall accuracy of the three-level potency ranking was 78%. The classification of chemicals as irritating versus non-irritating resulted in 96% sensitivity, 91% specificity and 95% accuracy. 2015 FRAME.

    Safety checklist is a type of cognitive tool enforcing short term memory of medical workers with the purpose of reducing medical errors caused by overlook and ignorance. To facilitate the daily use of safety checklists, computerized systems embedded in the clinical workflow and adapted to patient-context are increasingly developed. However, the current hard-coded approach of implementing checklists in these systems increase the cognitive efforts of clinical experts and coding efforts for informaticists. This is due to the lack of a formal representation format that is both understandable by clinical experts and executable by computer programs. We developed a dynamic checklist meta-model with a three-step approach. Dynamic checklist modeling requirements were extracted by performing a domain analysis. Then, existing modeling approaches and tools were investigated with the purpose of reusing these languages. Finally, the meta-model was developed by eliciting domain concepts and their hierarchies. The feasibility of using the meta-model was validated by two case studies. The meta-model was mapped to specific modeling languages according to the requirements of hospitals. Using the proposed meta-model, a comprehensive coronary artery bypass graft peri-operative checklist set and a percutaneous coronary intervention peri-operative checklist set have been developed in a Dutch hospital and a Chinese hospital, respectively. The result shows that it is feasible to use the meta-model to facilitate the modeling and execution of dynamic checklists. We proposed a novel meta-model for the dynamic checklist with the purpose of facilitating creating dynamic checklists. The meta-model is a framework of reusing existing modeling languages and tools to model dynamic checklists. The feasibility of using the meta-model is validated by implementing a use case in the system.

    Irritability is defined as a low threshold to experience anger in response to frustration. It is one of the most common symptoms in youth and is part of the clinical presentation of several disorders. Irritability can present early in life and is a predictor of long-term psychopathology; yet, the diagnostic status of irritability is a matter of intense debate. In the present article, we address two main components of the debate regarding irritability in youth: the misdiagnosis of chronic irritability as pediatric bipolar disorder, and the proposal of a new diagnosis in the DSM-5, disruptive mood dysregulation disorder, whose defining symptoms are chronic irritability and temper outbursts.

    An international study about implementation of the World Health Organization Surgical Safety Checklist showed that use of the checklist reduced complication and death rates in adult surgical patients. Clinicians at Children's Hospital Boston, Massachusetts, modified the Surgical Safety Checklist for pediatric populations. We pilot tested the Pediatric Surgical Safety Checklist and created a large checklist poster for each OR to allow the entire surgical team to view the checklist simultaneously and to promote shared responsibility for conducting the time out. Results of the pilot test showed improvements in teamwork, communication, and adherence to process measures. Parallel efforts were made in other areas of the hospital where invasive procedures are performed. Compliance with the checklist at our facility has been good, and team members have expressed satisfaction with the flow and content of the checklist. Copyright (c) 2010 AORN, Inc.

    Aim. We aimed to evaluate whether histrionic personality traits are associated with irritability during conscious sedation endoscopy (CSE). Materials and Methods. A prospective cross-sectional study was planned. Irritability during CSE was classified into five grades: 0, no response; I, minimal movement; II, moderate movement; III, severe movement; IV, fighting against procedure. Patients in grades III and IV were defined as the irritable group. Participants were required to complete questionnaire sheet assessing the extent of histrionic personality traits, extraversion-introversion, and current psychological status. The present authors also collected basic sociodemographic data including alcohol use history. Results. A total of 32 irritable patients and 32 stable patients were analyzed. The histrionic personality trait score of the irritable group was higher than that of the stable group (9.5 ± 3.1 versus 6.9 ± 2.9; P = 0.001), as was the anxiety score (52.8 ± 8.6 versus 46.1 ± 9.6; P = 0.004). Heavy alcohol use was more frequently observed in the irritable group (65.6% versus 28.1%; P = 0.003). In multivariate analysis, all these three factors were independently correlated with irritability during CSE. Conclusion. This study revealed that histrionic personality traits, anxiety, and heavy alcohol use can affect irritability during CSE. PMID:25954307

    2015-04-01

    The purpose of this study is to review the relevant literature concerning work-associated irritable larynx syndrome (WILS), a hyperkinetic laryngeal disorder associated with occupational irritant exposure. Clinical symptoms are variable and include dysphonia, cough, dyspnoea and globus pharyngeus. WILS is a clinical diagnosis and can be difficult to differentiate from asthma. Treatment options for WILS include medical and behavioural therapy. Laryngeal-centred upper airway symptoms secondary to airborne irritants have been documented in the literature under a variety of diagnostic labels, including WILS, vocal cord dysfunction (VCD), laryngeal hypersensitivity and laryngeal neuropathy and many others. The underlying pathophysiology is as yet poorly understood; however, the clinical scenario suggests a multifactorial nature to the disorder. More recent literature indicates that central neuronal plasticity, inflammatory processes and psychological factors are all likely contributors. Possible mechanisms for WILS include central neuronal network plasticity after noxious exposure and/or viral infection, inflammation (i.e. reflux disease) and intrinsic patient factors such a psychological state. Treatment is individualized and frequently includes one or more of the following: environmental changes in the workplace, GERD therapy, behavioural/speech therapy, psychotherapy counselling and neural modifiers.

    There is high prevalence of mental and behavioral disorders in general hospitals, thus triggering psychiatric risk situations. This study aimed to develop a psychiatric risk assessment checklist and routine for nurses, the Psychiatric Risk Evaluation Check-List (PRE-CL), as an alternative model for early identification and management of these situations in general hospitals. Ethnographic qualitative study in a tertiary-level private hospital. Three hundred general-unit nurses participated in the study. Reports were gathered through open groups conducted by a trained nurse, at shift changes for two months. The questions used were: "Would you consider it helpful to discuss daily practice situations with a psychiatrist? Which situations?" The data were qualitatively analyzed through an ethnographic approach. The nurses considered it useful to discuss daily practice situations relating to mental and behavioral disorders with a psychiatrist. Their reports were used to develop PRE-CL, within the patient overall risk assessment routine for all inpatients within 24 hours after admission and every 48 hours thereafter. Whenever one item was present, the psychosomatic medicine team was notified. They went to the unit, gathered data from the nurses, patient files and, if necessary, attending doctors, and decided on the risk management: guidance, safety measures or mental health consultation. It is possible to develop a model for detecting and intervening in psychiatric and behavioral disorders at general hospitals based on nursing team observations, through a checklist that takes these observations into account and a routine inserted into daily practice.

    The goal of this study was to develop and evaluate the impact of an aviation-style challenge and response sinus surgery-specific checklist on potential safety and equipment issues during sinus surgery at a tertiary academic health center. The secondary goal was to assess the potential impact of use of the checklist on surgical times during, before, and after surgery. This initiative is designed to be utilized in conjunction with the "standard" World Health Organization (WHO) surgical checklist. Although endoscopic sinus surgery is generally considered a safe procedure, avoidable complications and potential safety concerns continue to occur. The WHO surgical checklist does not directly address certain surgery-specific issues, which may be of particular relevance for endoscopic sinus surgery. This prospective observational pilot study monitored compliance with and compared the occurrence of safety and equipment issues before and after implementation of the checklist. Forty-seven consecutive endoscopic surgeries were audited; the first 8 without the checklist and the following 39 with the checklist. The checklist was compiled by evaluating the patient journey, utilizing the available literature, expert consensus, and finally reevaluation with audit type cases. The final checklist was developed with all relevant stakeholders involved in a Delphi method. Implementing this specific surgical checklist in 39 cases at our institution, allowed us to identify and rectify 35 separate instances of potentially unsafe, improper or inefficient preoperative setup. These incidents included issues with labeling of topical vasoconstrictor or injectable anesthetics (3, 7.7%) and availability, function and/or position of video monitors (2, 5.1%), endoscope (6, 15.4%), microdebrider (6, 15.4%), bipolar cautery (6, 15.4%), and suctions (12, 30.8%). The design and integration of this checklist for endoscopic sinus surgery, has helped improve efficiency and patient safety in the operating

    Psychiatric comorbidity complicates clinical care and confounds efforts to elucidate the pathophysiology of commonly occurring symptoms in youths. To our knowledge, few studies have simultaneously assessed the effect of 2 continuously distributed traits on brain-behavior relationships in children with psychopathology. To determine shared and unique effects of 2 major dimensions of child psychopathology, irritability and anxiety, on neural responses to facial emotions during functional magnetic resonance imaging. Cross-sectional functional magnetic resonance imaging study in a large, well-characterized clinical sample at a research clinic at the National Institute of Mental Health. The referred sample included youths ages 8 to 17 years, 93 youths with anxiety, disruptive mood dysregulation, and/or attention-deficit/hyperactivity disorders and 22 healthy youths. The child's irritability and anxiety were rated by both parent and child on the Affective Reactivity Index and Screen for Child Anxiety Related Disorders, respectively. Using functional magnetic resonance imaging, neural response was measured across the brain during gender labeling of varying intensities of angry, happy, or fearful face emotions. In mixed-effects analyses, the shared and unique effects of irritability and anxiety were tested on amygdala functional connectivity and activation to face emotions. The mean (SD) age of participants was 13.2 (2.6) years; of the 115 included, 64 were male. Irritability and/or anxiety influenced amygdala connectivity to the prefrontal and temporal cortex. Specifically, irritability and anxiety jointly influenced left amygdala to left medial prefrontal cortex connectivity during face emotion viewing (F4,888 = 9.20; P < .001 for mixed model term). During viewing of intensely angry faces, decreased connectivity was associated with high levels of both anxiety and irritability, whereas increased connectivity was associated with high levels of anxiety but low levels

    The strategy used to improve effective checklist use in intensive care unit (ICU) setting is essential for checklist success. This study aimed to test the hypothesis that an electronic checklist could reduce ICU provider workload, errors, and time to checklist completion, as compared to a paper checklist. This was a simulation-based study conducted at an academic tertiary hospital. All participants completed checklists for 6 ICU patients: 3 using an electronic checklist and 3 using an identical paper checklist. In both scenarios, participants had full access to the existing electronic medical record system. The outcomes measured were workload (defined using the National Aeronautics and Space Association task load index [NASA-TLX]), the number of checklist errors, and time to checklist completion. Two independent clinician reviewers, blinded to participant results, served as the reference standard for checklist error calculation. Twenty-one ICU providers participated in this study. This resulted in the generation of 63 simulated electronic checklists and 63 simulated paper checklists. The median NASA-TLX score was 39 for the electronic checklist and 50 for the paper checklist (P = .005). The median number of checklist errors for the electronic checklist was 5, while the median number of checklist errors for the paper checklist was 8 (P = .003). The time to checklist completion was not significantly different between the 2 checklist formats (P = .76). The electronic checklist significantly reduced provider workload and errors without any measurable difference in the amount of time required for checklist completion. This demonstrates that electronic checklists are feasible and desirable in the ICU setting. © The Author(s) 2014.

    Abstract Objective The aim of this study was to determine the effectiveness and tolerability of aripiprazole for irritability in pervasive developmental disorder not otherwise specified (PDD-NOS) and Asperger's disorder. Method This is a 14-week, prospective, open-label investigation of aripiprazole in 25 children and adolescents diagnosed with PDD-NOS or Asperger's disorder. Primary outcome measures included the Clinical Global Impressions–Improvement (CGI-I) scale and the Irritability subscale of the Aberrant Behavior Checklist (ABC-I). Results Twenty-five subjects, ages 5–17 years (mean 8.6 years) received a mean final aripiprazole dosage of 7.8 mg/day (range 2.5–15 mg/day). Full-scale intelligence quotient (IQ) scores ranged from 48 to 122 (mean 84). Twenty-two (88%) of 25 subjects were responders in regard to interfering symptoms of irritability, including aggression, self-injury, and tantrums, with a final CGI-I of 1 or 2 (very much or much improved) and a 25% or greater improvement on the ABC-I. The final mean CGI-I was 1.6 (p ≤ 0.0001). ABC-I scores ranged from 18 to 43 (mean 29) at baseline, whereas scores at week 14 ranged from 0 to 27 (mean 8.1) (p ≤ 0.001). Aripiprazole was well tolerated. Mild extrapyramidal symptoms (EPS) were reported in 9 subjects. Age- and sex-normed body mass index (BMI) increased from a mean value of 20.3 at baseline to 21.1 at end point (p ≤ 0.04). Prolactin significantly decreased from a mean value of 9.3 at baseline to 2.9 at end point (p ≤ 0.0001). No subject exited the study due to a drug-related adverse event. Conclusions These preliminary data suggest that aripiprazole may be effective and well tolerated for severe irritability in pediatric patients with PDD-NOS or Asperger's disorder. Larger-scale placebo-controlled studies are needed to elucidate the efficacy and tolerability of aripiprazole in this understudied population. PMID:19519261

    Checklists and monitoring are two essential defenses against equipment failures and pilot errors. Problems with checklist use and pilots failures to monitor adequately have a long history in aviation accidents. This study was conducted to explore why checklists and monitoring sometimes fail to catch errors and equipment malfunctions as intended. Flight crew procedures were observed from the cockpit jumpseat during normal airline operations in order to: 1) collect data on monitoring and checklist use in cockpit operations in typical flight conditions; 2) provide a plausible cognitive account of why deviations from formal checklist and monitoring procedures sometimes occur; 3) lay a foundation for identifying ways to reduce vulnerability to inadvertent checklist and monitoring errors; 4) compare checklist and monitoring execution in normal flights with performance issues uncovered in accident investigations; and 5) suggest ways to improve the effectiveness of checklists and monitoring. Cognitive explanations for deviations from prescribed procedures are provided, along with suggestions for countermeasures for vulnerability to error.

    Aim The parent form of the 113 item Child Behavior Checklist (CBCL) is widely utilized by child psychiatrists and psychologists. This report examines the reliability and validity of a recently developed abbreviated version of the CBCL, the Brief Problem Monitor (BPM). Methods Caregivers (N=567) completed the CBCL online and the 19 BPM items were examined separately. Results Internal consistency of the BPM was high (Cronbach’s alpha=0.91) and satisfactory for the Internalizing (0.78), Externalizing (0.86), and Attention (0.87) scales. High correlations between the CBCL and BPM were identified for the total score (r=0.95) as well as the Internalizing (0.86), Externalizing (0.93), and Attention (0.97) scales. The BPM and scales were sensitive and identified significantly higher behavioral and emotional problems among children whose caregiver reported a psychiatric diagnosis of Attention Deficit Hyperactivity Disorder, bipolar, depression, anxiety, developmental disabilities, or Autism Spectrum Disorders relative to a comparison group that had not been diagnosed with these disorders. BPM ratings also differed by the socioeconomic status and education of the caregiver. Mothers with higher annual incomes rated their children as having 38.8% fewer total problems (Cohen’s d=0.62) as well as 42.8% lower Internalizing (d=0.53), 44.1% less Externalizing (d=0.62), and 30.9% decreased Attention (d=0.39). A similar pattern was evident for maternal education (d=0.30 to 0.65). Conclusion Overall, these findings provide strong psychometric support for the BPM although the differences based on the characteristics of the parent indicates that additional information from other sources (e.g., teachers) should be obtained to complement parental reports.

  14. The upper respiratory tract: mucous membrane irritation.

    Despite the widespread recognition that mucosal irritation is a cardinal feature of "sick-building syndrome," few data exist on the cause, natural history, or pathophysiology of upper respiratory mucous membrane irritation. The baseline prevalence of nasal symptoms among building occupants is often 20%, but in some studies it is as high as 50 to 60%. New techniques of nasal challenge and analysis of cells and mediators in nasal lavage fluid have proved useful in the assessment of rhinitis caused by antigens, cold air, and viruses, and these techniques are now being applied to the study the response to irritants. Human inhalation challenge studies have recently demonstrated a spectrum of sensitivity to environmental tobacco smoke, but the basis for this difference requires additional investigation. Animal and in vitro studies indicate that the chemosensitive neurons and airway epithelium may be critical targets for irritants that participate in the induction of inflammation. New research methods are needed, particularly to evaluate complaints of nasal congestion, drying, and irritation. Techniques should be developed that may be useful for field studies, where the health effects of a complex mixture are being assessed in a specific indoor environment. There exists a group of individuals who report a variety of symptoms on exposure to low levels of common volatile organic mixtures such as perfume, cigarette smoke, and cleaning agents. Some of these individuals report having occupied "sick buildings" during the time their symptoms began. Research is needed to understand the basis of their complaints, their etiology, and treatment.

    Moisturizers are used daily by many people to alleviate symptoms of dry skin. All of them contain lipids. It has been suggested that topically applied lipids may interfere with the structure and function of the permeability barrier. The influence of a single application of nine different lipids on normal skin and skin irritated by sodium lauryl sulphate (SLS) was studied in 21 healthy subjects. Parameters assessed were visible signs of irritation, and objectively measured cutaneous blood flow and transepidermal water loss (TEWL). The substances tested were hydrocortisone, petrolatum, fish oil, borage oil, sunflower seed oil, canola oil, shea butter, and fractions of unsaponifiable lipids from canola oil and shea butter. Water was included as a control. On normal skin, no significant differences in the effects of the test substances were found, whereas significant differences were observed when they were applied to SLS-irritated skin. The visible signs of SLS-induced irritation were significantly less pronounced after treatment with the sterol-enriched fraction from canola oil than after treatment with water. This fraction, and hydrocortisone, reduced cutaneous blood flow. Furthermore, application of hydrocortisone, canola oil, and its sterol-enriched fraction, resulted in significantly lower TEWL than with water. The other lipids had no effect on the degree of irritation. In conclusion, lipids commonly used in moisturizers may reduce skin reactions to irritants. Previous studies have shown that, in barrier perturbed skin, the synthesis of sterols is increased. The observed effects of canola oil and its fraction of unsaponifiable lipids on SLS-induced irritation suggest the possibility that they assisted the skin in supplying the damaged barrier with adequate lipids.

    This study describes the types, causes, and outcomes of potential irritation and allergy incidents among workers in British Columbia's health care industry. Data on occupation-induced allergy and irritation incidents were extracted from a standardized database using the number of productive hours obtained from payroll data as a denominator during a 1-year period from three British Columbia health regions. Younger workers, female workers, facility support service workers, laboratory assistants and technicians, and maintenance and acute care workers were found to be at higher risk for allergy and irritation incidents. Major causes of allergy and irritation incidents included chemicals, blood and body fluids, food and objects, communicable diseases, air quality, and latex. A larger proportion of chemically induced incidents resulted in first aid care only, whereas non-chemical incidents required more emergency room visits.

    Complimentary alternative treatment regimens are widely used in irritable bowel syndrome (IBS), but the evidence supporting their use varies. For psychological treatment options, such as cognitive behavioral therapy, mindfulness, gut-directed hypnotherapy, and psychodynamic therapy, the evidence supporting their use in IBS patients is strong, but the availability limits their use in clinical practice. Dietary interventions are commonly included in the management of IBS patients, but these are primarily based on studies assessing physiological function in relation to dietary components, and to a lesser degree upon research examining the role of dietary components in the therapeutic management of IBS. Several probiotic products improve a range of symptoms in IBS patients. Physical activity is of benefit for health in general and recent data implicates its usefulness also for IBS patients. Acupuncture does not seem to have an effect beyond placebo in IBS. A beneficial effect of some herbal treatments has been reported.

    Agreement between client and therapist on treatment goals has been consistently linked with improved treatment outcomes. Having clear and collaborative goals may be particularly important when working with clients diagnosed with personality disorders who are often difficult to engage and test the boundaries of therapy. This paper outlines the development of a personality disorder treatment goal checklist aimed at helping clients and therapists to identify and prioritize their goals for therapy. The checklist was developed using self-reported problems of the first 90 participants randomized into the psychoeducation and problem solving (PEPS) trial. Problems were coded and categorized into problem areas. The checklist was viewed by two service users who gave suggestions for improvements. The final checklist consists of 161 items in 16 problem areas. The checklist may provide a clinically useful tool for working with this client group. Copyright © 2013 John Wiley & Sons, Ltd.

    To evaluate two checklist tools that are designed to guide, document, and assess resident training in strabismus surgery and examination of infants at risk for retinopathy of prematurity (ROP). A panel of staff surgeons from several teaching institutions evaluated the checklists and provided constructive feedback. All former residents who had been trained via the use of these checklist tools were asked to take self-assessment surveys on competency in strabismus surgery and ROP examination. A Likert 5-point scale was used for all evaluations, with 1 being the lowest rating and 5 the highest rating. Six experts in strabismus and seven in ROP rated the checklists. Their comments were used to revise the checklists, which were sent to the same group for reevaluation. The mean Likert score for the final checklists was 4.9 of 5.0 for both checklists. Of 16 former residents, 9 responded to the self-assessments with a mean overall score of 4.1 (of 5.0) for strabismus surgery and 3.9 for ROP examination. These checklist tools can be used to assess the quality of a resident's training and experience in these specific ophthalmology skills. They are complementary to other curriculum and assessment tools and can serve to organize the educational experience while ensuring a uniformity of training. Published by Mosby, Inc.

    Biogenic amines are potential irritants e.g. in fish-, meat-, milk- and egg-processing professions like cooks, butchers and bakers. The aim of this study was to test the irritative and barrier-disrupting properties of the biogenic amines ammonium hydroxide (AM), dimethylamine (DMA) and trimethylamine (TMA). A repeated sequential irritation of 30 min twice per day was performed over a total of 4 days (tandem repeated irritation test) on the back of 20 healthy volunteers of both sexes with AM, DMA, TMA and sodium lauryl sulphate (SLS). The epidermal barrier function was assessed with a Tewameter TM 210, stratum corneum surface pH was measured with a Skin-pH-Meter 900, inflammation was assessed with a Chromameter CR-300 on the a* axis for redness and a visual score was recorded. All tested biogenic amines (AM, DMA and TMA) induced a barrier disruption and a pH increase paralleled with a 1-day-delayed onset of inflammatory signs. These effects were further enhanced and accelerated by a sequential application of SLS together with the biogenic amines, and inflammation occurred earlier than with the single compounds. Acetic acid (AA) in contrast did only show mild barrier disruption and no significant inflammatory signs. Our system allowed a ranking of the different compounds in their irritative potential in the tandem irritation with SLS: SLS > NaOH > TMA > AA > AM > DMA. The results are suggestive that in the food-processing industry the simultaneous contact with biogenic amines and harmful detergents like SLS should be minimized. Copyright 2005 S. Karger AG, Basel.

  5. Correlations between corneal and total wavefront aberrations

    Purpose: Corneal topography data expressed as corneal aberrations are frequently used to report corneal laser surgery results. However, the optical image quality at the retina depends on all optical elements of the eye such as the human lens. Thus, the aim of this study was to investigate the correlations between the corneal and total wavefront aberrations and to discuss the importance of corneal aberrations for representing corneal laser surgery results. Methods: Thirty three eyes of 22 myopic subjects were measured with a corneal topography system and a Tschernig-type wavefront analyzer after the pupils were dilated to at least 6 mm in diameter. All measurements were centered with respect to the line of sight. Corneal and total wavefront aberrations were calculated up to the 6th Zernike order in the same reference plane. Results: Statistically significant correlations (p < 0.05) between the corneal and total wavefront aberrations were found for the astigmatism (C3,C5) and all 3rd Zernike order coefficients such as coma (C7,C8). No statistically significant correlations were found for all 4th to 6th order Zernike coefficients except for the 5th order horizontal coma C18 (p equals 0.003). On average, all Zernike coefficients for the corneal aberrations were found to be larger compared to Zernike coefficients for the total wavefront aberrations. Conclusions: Corneal aberrations are only of limited use for representing the optical quality of the human eye after corneal laser surgery. This is due to the lack of correlation between corneal and total wavefront aberrations in most of the higher order aberrations. Besides this, the data present in this study yield towards an aberration balancing between corneal aberrations and the optical elements within the eye that reduces the aberration from the cornea by a certain degree. Consequently, ideal customized ablations have to take both, corneal and total wavefront aberrations, into consideration.

    The Bovine Corneal Opacity and Permeability (BCOP) test is commonly used for the identification of severe ocular irritants (GHS Category 1), but it is not recommended for the identification of ocular irritants (GHS Category 2). The incorporation of human reconstructed tissue model-based tests into a tiered test strategy to identify ocular non-irritants and replace the Draize rabbit eye irritation test has been suggested (OECD TG 405). The value of the EpiOcular™ Eye Irritation Test (EIT) for the prediction of ocular non-irritants (GHS No Category) has been demonstrated, and an OECD Test Guideline (TG) was drafted in 2014. The purpose of this study was to evaluate whether the BCOP test, in conjunction with corneal histopathology (as suggested for the evaluation of the depth of the injury( and/or the EpiOcular-EIT, could be used to predict the eye irritation potential of agrochemical formulations according to the UN GHS, US EPA and Brazil ANVISA classification schemes. We have assessed opacity, permeability and histopathology in the BCOP assay, and relative tissue viability in the EpiOcular-EIT, for 97 agrochemical formulations with available in vivo eye irritation data. By using the OECD TG 437 protocol for liquids, the BCOP test did not result in sufficient correct predictions of severe ocular irritants for any of the three classification schemes. The lack of sensitivity could be improved somewhat by the inclusion of corneal histopathology, but the relative viability in the EpiOcular-EIT clearly outperformed the BCOP test for all three classification schemes. The predictive capacity of the EpiOcular-EIT for ocular non-irritants (UN GHS No Category) for the 97 agrochemical formulations tested (91% sensitivity, 72% specificity and 82% accuracy for UN GHS classification) was comparable to that obtained in the formal validation exercise underlying the OECD draft TG. We therefore conclude that the EpiOcular-EIT is currently the best in vitro method for the prediction

    Background The use of checklists to minimise errors is well established in high reliability, safety-critical industries. In health care there is growing interest in checklists to standardise checking processes and ensure task completion, and so provide further systemic defences against error and patient harm. However, in UK general practice there is limited experience of safety checklist use. Aim To identify workplace hazards that impact on safety, health and wellbeing, and performance, and codesign a standardised checklist process. Design and setting Application of mixed methods to identify system hazards in Scottish general practices and develop a safety checklist based on human factors design principles. Method A multiprofessional ‘expert’ group (n = 7) and experienced front-line GPs, nurses, and practice managers (n = 18) identified system hazards and developed and validated a preliminary checklist using a combination of literature review, documentation review, consensus building workshops using a mini-Delphi process, and completion of content validity index exercise. Results A prototype safety checklist was developed and validated consisting of six safety domains (for example, medicines management), 22 sub-categories (for example, emergency drug supplies) and 78 related items (for example, stock balancing, secure drug storage, and cold chain temperature recording). Conclusion Hazards in the general practice work system were prioritised that can potentially impact on the safety, health and wellbeing of patients, GP team members, and practice performance, and a necessary safety checklist prototype was designed. However, checklist efficacy in improving safety processes and outcomes is dependent on user commitment, and support from leaders and promotional champions. Although further usability development and testing is necessary, the concept should be of interest in the UK and internationally. PMID:25918338

    Endotransformations and aberrations of the life cycle in the evolutionary history of trypanosomatids (Kinetoplastea: Trypanosomatidae) are analyzed. We treat the term "endotransformations" as evolutionarily fixed changes of phases and/or developmental stages of parasites. By contrast, we treat aberrations as evolutionary unstable, periodically arising deformations of developmental phases of trypanosomatids, never leading to life cycle changes. Various examples of life cycle endotransformations and aberrations in representatives of the family Trypanosomatidae are discussed.

    This is an investigation of minocycline efficacy and safety as an adjuvant to risperidone in management of children with autism. Forty-six children with diagnosis of autistic disorder, according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) criteria and a score of ≥12 on the Aberrant Behavior Checklist-Community (ABC-C) irritability subscale, who were already drug-free for at least 6 months participated in a randomized controlled trial and underwent 10 weeks of treatment with either minocycline (50 mg twice per day) or placebo in addition to risperidone titrated up to 2 mg/day (based on bodyweight). Patients were evaluated using ABC-C at baseline and at weeks 5 and 10. General linear model repeated measures showed significant effect for time × treatment interaction on the irritability [F(2, 88) = 3.94, p = 0.02] and hyperactivity/noncompliance [F(1.50, 66.05) = 7.92, p = 0.002], but not for lethargy/social withdrawal [F(1.61, 71.02) = 0.98, p = 0.36], stereotypic behavior [F(1.34, 58.80) = 1.55, p = 0.22], and inappropriate speech subscale scores [F(1.52, 66.88) = 1.15, p = 0.31]. By week 10, 21 (91.3%) patients in the minocycline group and 15 (65.5%) patients in the placebo group achieved at least partial response (p = 0.03). Frequencies of adverse events were not significantly different between groups. Minocycline seems to be a safe and effective adjuvant in management of patients with autistic disorder. Future studies with larger sample sizes, longer follow-ups, and inflammatory cytokine measurements are warranted to confirm these findings and provide insight into minocycline mechanism of action in autistic disorder.

    The aim of this review is to present a realist synthesis of the evidence of implementation interventions to improve adherence to the use of safety checklists in surgery. Surgical safety checklists have been shown to improve teamwork and patient safety in the operating room. Yet, despite the benefits associated with their use, universal implementation of and compliance with these checklists has been inconsistent. An overview of the literature from 2008 is examined in relation to checklist implementation, compliance, and sustainability. Pawson's and Rycroft-Malone's realist synthesis methodology was used to explain the interaction between context, mechanism, and outcome. This approach incorporated the following: defining the scope of the review, searching and appraising the evidence, extracting and synthesising the findings, and disseminating, implementing, and evaluating the evidence. We identified two theories a priori that explained contextual nuances associated with implementation and evaluation of checklists in surgery: the Normalisation Process Theory and Responsive Regulation Theory. We identified four a priori propositions: (1) Checklist protocols that are prospectively tailored to the context are more likely to be used and sustained in practice, (2) Fidelity and sustainability is increased when checklist protocols can be seamlessly integrated into daily professional practice, (3) Routine embedding of checklist protocols in practice is influenced by factors that promote or inhibit clinicians' participation, and (4) Regulation reinforcement mechanisms that are more contextually responsive should lead to greater compliance in using checklist protocols. The final explanatory model suggests that the sustained use of surgical checklists is discipline-specific and is more likely to occur when medical staff are actively engaged and leading the process of implementation. Involving clinicians in tailoring the checklist to better fit their context of practice and

    Bipolar disorder and disruptive mood dysregulation disorder (DMDD) are clinically and pathophysiologically distinct, yet irritability can be a clinical feature of both illnesses. The authors examine whether the neural mechanisms mediating irritability differ between bipolar disorder and DMDD, using a face emotion labeling paradigm because such labeling is deficient in both patient groups. The authors hypothesized that during face emotion labeling, irritability would be associated with dysfunctional activation in the amygdala and other temporal and prefrontal regions in both disorders, but that the nature of these associations would differ between DMDD and bipolar disorder. During functional MRI acquisition, 71 youths (25 with DMDD, 24 with bipolar disorder, and 22 healthy youths) performed a labeling task with happy, fearful, and angry faces of varying emotional intensity. Participants with DMDD and bipolar disorder showed similar levels of irritability and did not differ from each other or from healthy youths in face emotion labeling accuracy. Irritability correlated with amygdala activity across all intensities for all emotions in the DMDD group; such correlation was present in the bipolar disorder group only for fearful faces. In the ventral visual stream, associations between neural activity and irritability were found more consistently in the DMDD group than in the bipolar disorder group, especially in response to ambiguous angry faces. These results suggest diagnostic specificity in the neural correlates of irritability, a symptom of both DMDD and bipolar disorder. Such evidence of distinct neural correlates suggests the need to evaluate different approaches to treating irritability in the two disorders.

    Identification and reduction of external noxious factors is one key point in the strategy for the treatment and reduction of contact dermatitis. A wide variety of soaps on the market are claimed to be suitable for the use on sensitive skin due to their mildness. The aim of the present study was to illustrate possible differences in the irritation potential of 8 products and to investigate whether surfactant residues may form an irritant reservoir on the skin. The study was double-blind, randomized using healthy human volunteers. The inherent capacity of the products to induce irritation was determined using conventional patch test technique, whereas detection of potential surfactant residues on the skin was done using a methodology developed in the 1960s for detection of the corticosteroid reservoir in the stratum corneum. The method comprised the release of active substance from the stratum corneum reservoir by occlusion of the skin with an aluminium chamber, followed by evaluation of the biological response. In the present study, the soap-treated area was rinsed with water and then occluded. Instrumental measurements of the transepidermal water loss and superficial skin blood flow served as indicators of the injurious effects of the products. The results showed large differences in irritation potential between the products, and some of them demonstrated considerable damaging effect. Moreover, the study proved the presence of barrier-impairing residues on the skin after rinsing with water. Subclinical skin damage can make the skin vulnerable to further irritation and delay recovery of chronic irritant contact dermatitis.

    This study forms part of a project investigating the relationships among the formal structure of aviation procedures, the ways in which the crew members are taught to execute them, and the ways in which thet are actually performed in flight. Specifically, this report examines the interactions between the performance of checklists and interruptions, considering both interruptions by radio communications and by other crew members. The data consists of 14 crews' performance of a full mission simulation of a higher ratio of checklist speech acts to all speech acts within the span of the performance of the checklist. Further, it is not number of interruptions but length of interruptions which is associated with crew performance quality. Use of explicit holds is also associated with crew performance.

    High-order monochromatic aberrations could potentially influence vision-dependent refractive development in a variety of ways. As a first step in understanding the effects of wave aberration on refractive development, we characterized the maturational changes that take place in the high-order aberrations of infant rhesus monkey eyes. Specifically, we compared the monochromatic wave aberrations of infant and adolescent animals and measured the longitudinal changes in the high-order aberrations of infant monkeys during the early period when emmetropization takes place. Our main findings were that (1) adolescent monkey eyes have excellent optical quality, exhibiting total RMS errors that were slightly better than those for adult human eyes that have the same numerical aperture and (2) shortly after birth, infant rhesus monkeys exhibited relatively larger magnitudes of high-order aberrations predominately spherical aberration, coma, and trefoil, which decreased rapidly to assume adolescent values by about 200 days of age. The results demonstrate that rhesus monkey eyes are a good model for studying the contribution of individual ocular components to the eye’s overall aberration structure, the mechanisms responsible for the improvements in optical quality that occur during early ocular development, and the effects of high-order aberrations on ocular growth and emmetropization.

  3. Checklists in Neurosurgery to Decrease Preventable Medical Errors: A Review

    PubMed Central

    Enchev, Yavor

    2015-01-01

    Neurosurgery represents a zero tolerance environment for medical errors, especially preventable ones like all types of wrong site surgery, complications due to the incorrect positioning of patients for neurosurgical interventions and complications due to failure of the devices required for the specific procedure. Following the excellent and encouraging results of the safety checklists in intensive care medicine and in other surgical areas, the checklist was naturally introduced in neurosurgery. To date, the reported world experience with neurosurgical checklists is limited to 15 series with fewer than 20,000 cases in various neurosurgical areas. The purpose of this review was to study the reported neurosurgical checklists according to the following parameters: year of publication; country of origin; area of neurosurgery; type of neurosurgical procedure-elective or emergency; person in charge of the checklist completion; participants involved in completion; whether they prevented incorrect site surgery; whether they prevented complications due to incorrect positioning of the patients for neurosurgical interventions; whether they prevented complications due to failure of the devices required for the specific procedure; their specific aims; educational preparation and training; the time needed for checklist completion; study duration and phases; number of cases included; barriers to implementation; efforts to implementation; team appreciation; and safety outcomes. Based on this analysis, it could be concluded that neurosurgical checklists represent an efficient, reliable, cost-effective and time-saving tool for increasing patient safety and elevating the neurosurgeons’ self-confidence. Every neurosurgical department must develop its own neurosurgical checklist or adopt and modify an existing one according to its specific features and needs in an attempt to establish or develop its safety culture.

  4. Iteration of ultrasound aberration correction methods

    2004-05-01

    Aberration in ultrasound medical imaging is usually modeled by time-delay and amplitude variations concentrated on the transmitting/receiving array. This filter process is here denoted a TDA filter. The TDA filter is an approximation to the physical aberration process, which occurs over an extended part of the human body wall. Estimation of the TDA filter, and performing correction on transmit and receive, has proven difficult. It has yet to be shown that this method works adequately for severe aberration. Estimation of the TDA filter can be iterated by retransmitting a corrected signal and re-estimate until a convergence criterion is fulfilled (adaptive imaging). Two methods for estimating time-delay and amplitude variations in receive signals from random scatterers have been developed. One method correlates each element signal with a reference signal. The other method use eigenvalue decomposition of the receive cross-spectrum matrix, based upon a receive energy-maximizing criterion. Simulations of iterating aberration correction with a TDA filter have been investigated to study its convergence properties. A weak and strong human-body wall model generated aberration. Both emulated the human abdominal wall. Results after iteration improve aberration correction substantially, and both estimation methods converge, even for the case of strong aberration.

    Leyden, James J; Grossman, Rachel; Nighland, Marge

    2008-08-01

    Localized irritation can limit treatment success with topical retinoids such as tretinoin and adapalene. The factors that influence irritant reactions have been shown to include individual skin sensitivity, the particular retinoid and concentration used, and the vehicle formulation. To compare the cutaneous tolerability of tretinoin 0.04% microsphere gel (TMG) with that of adapalene 0.3% gel and a standard tretinoin 0.025% cream. The results of 2 randomized, investigator-blinded studies of 2 to 3 weeks' duration, which utilized a split-face method to compare cumulative irritation scores induced by topical retinoids in subjects with healthy skin, were combined. Study 1 compared TMG 0.04% with adapalene 0.3% gel over 2 weeks, while study 2 compared TMG 0.04% with tretinoin 0.025% cream over 3 weeks. In study 1, TMG 0.04% was associated with significantly lower cumulative scores for erythema, dryness, and burning/stinging than adapalene 0.3% gel. However, in study 2, there were no significant differences in cumulative irritation scores between TMG 0.04% and tretinoin 0.025% cream. Measurements of erythema by a chromameter showed no significant differences between the test formulations in either study. Cutaneous tolerance of TMG 0.04% on the face was superior to that of adapalene 0.3% gel and similar to that of a standard tretinoin cream containing a lower concentration of the drug (0.025%).

    2013-10-01

    We previously reported that the time-dependent relative changes of transepithelial electrical resistance (TEER) after exposing four different chemicals to a human corneal epithelium (HCE) model were well correlated to the potential of ocular irritancy. Meanwhile, we recently developed a collagen vitrigel membrane (CVM) chamber possessing a scaffold composed of high-density collagen fibrils equivalent to connective tissues in vivo as a three-dimensional culture tool. The CVM chamber is useful for biomedical assays and immunohistology using cryosections that are inappropriate to be performed using the conventional Millicell chamber with a polyethylene terephthalate membrane. In this study, we aimed to develop a new eye irritancy test (EIT) method called "Vitrigel-EIT method" that can facilitate to briefly and accurately estimate the widespread irritancy of test chemicals by applying the TEER assay system to a HCE model fabricated in the CVM chamber. HCE-T cells (a HCE-derived cell strain) were cultured in the CVM chamber for 6 days, and consequently, the Vitrigel-HCE model possessing the following characteristics of HCE in vivo was formed: six cell layers with specific protein expressions and their barrier function. Time-dependent profiles of TEER values after exposing 30 test chemicals to the HCE model were converted into the scores of three indexes (time lag, intensity, and plateau level), and each chemical was successfully classified into irritant or nonirritant category by utilizing the criteria for the indexes, resulting in the excellent correlation with Globally Harmonized System of Classification and Labelling of Chemicals (GHS) classification (sensitivity: 100%, specificity: 75%, accuracy: 90%). These data suggest that the widespread eye irritancy of chemicals can be predicted without false negatives by the Vitrigel-EIT method. Interestingly, the disruption of tight junctions was immunohistologically observed after exposing not only irritants but also three

    In surgery, preoperative handover of surgical trauma patients is a process that must be made as safe as possible. We sought to determine vital clinical information to be transferred between patient care teams and to develop a standardized handover checklist. We conducted standardized small-group interviews about trauma patient handover. Based on this information, we created a questionnaire to gather perspectives from all Canadian Orthopaedic Association (COA) members about which topics they felt would be most important on a handover checklist. We analyzed the responses to develop a standardized handover checklist. Of the 1106 COA members, 247 responded to the questionnaire. The top 7 topics felt to be most important for achieving patient safety in the handover were comorbidities, diagnosis, readiness for the operating room, stability, associated injuries, history/mechanism of injury and outstanding issues. The expert recommendations were to have handover completed the same way every day, all appropriate radiographs available, adequate time, all appropriate laboratory work and more time to spend with patients with more severe illness. Our main recommendations for safe handover are to use standardized checklists specific to the patient and site needs. We provide an example of a standardized checklist that should be used for preoperative handovers. To our knowledge, this is the first checklist for handover developed by a group of experts in orthopedic surgery, which is both manageable in length and simple to use.

  13. Apoptosis in the areas of squamous differentiation of irritated seborrheic keratosis.

    PubMed

    Pesce, C; Scalora, S

    2000-03-01

    Seborrheic keratosis (SK) consists of a localized proliferation of basaloid keratinocytes, often accompanied by hyperkeratosis and hyperpigmentation. In irritated SK, these features are associated with areas of squamous differentiation with larger keratinocytes and squamous cell eddies. This work is concerned with the evaluation of apoptosis, as demonstrated by the TUNEL method, in the different varieties of SK. Apoptosis was highly expressed in the areas of squamous differentiation of irritated SK, but only mildly increased in the other varieties of SK. These data support the hypothesis that apoptosis has a role in the squamous differentiation of irritated SK. In consideration also of previous data showing that irritated SK is associated with downregulation of EGF-R expression and 125I-EGF binding, we postulate that the morphologic features of irritated SK could correspond to an involution phase of the disease, characterized by altered cell balance with inadequate cell renewal and increased cell loss.

    Checklists have been used to improve quality in many industries, including healthcare. The use of checklists, however, has not been extensively evaluated in clinical ethics consultation. This article seeks to fill this gap by exploring the efficacy of using a checklist in ethics consultation, as tested by an empirical investigation of the use of the checklist at a large academic medical system (Cleveland Clinic). The specific aims of this project are as follows: (1) to improve the quality of ethics consultations by providing reminders to ethics consultants about process steps that are important for most patient-centered ethics consultations, (2) to create consistency in the ethics consultation process across the medical system, and (3) to establish an effective educational tool for trainers and trainees in clinical ethics consultation. The checklist was developed after a thorough literature review and an iterative process of revising and testing by a group of experienced ethics consultants. To pilot test the checklist, it was distributed to 46 ethics professionals. After a six-month pilot period in which ethics professionals used the checklist during their clinical activities, a survey was distributed to all of those who used the checklist. The 10-item survey examined consultants' perceptions regarding the three aims listed above. Of the 25 survey respondents, 11 self-reported as experts in ethics consultation, nine perceived themselves to have mid-level expertise, and five self-reported as novices. The majority (68 percent) of all respondents, regardless of expertise, believed that the checklist could be a “helpful” or “very helpful” tool in the consultation process generally. Novices were more likely than experts to believe that the checklist would be useful in conducting consultations. The limitations of this study include: reduced generalizability given that this project was conducted at one medical system, utilized a small sample size, and used self

    The purpose of this investigation was to apply an arthroscopic shoulder and knee checklist in the evaluation of orthopedic resident arthroscopic skill efficiency and to demonstrate the use of a surgical checklist for assessing resident surgical efficiency over the course of a surgical rotation. Orthopedic surgery residents rotating on the sports medicine service at our institution between 2011 and 2015 were enrolled in this study. Residents were administered a shoulder and knee arthroscopy assessment tool at the beginning and end of their 6-week rotation. The assessment tools consisted of checklist items for knee and shoulder arthroscopy skills. Residents were timed while performing these checklist tasks. The primary outcome measure was resident improvement as a function of time to completion for the checklist items, and the intervention was participation in a 6-week resident rotation with weekly arthroscopy didactics, cadaver simulator work, and operating room experience. A paired t test was used to compare means. Mean time to checklist completion during week 1 among study participants for the knee checklist was 787.4 seconds for the knee checklist and 484.4 seconds at the end of the rotation. Mean time to checklist completion during week 1 among study participants for the shoulder checklist was 1655.3 seconds and 832.7 seconds for the shoulder checklist at the end of the rotation. Mean improvement in time to completion was 303 seconds (p = 0.0006, SD = 209s) and 822.6 seconds (p = 0.00008, SD = 525.2s) for the arthroscopic knee and shoulder assessments, respectively. An arthroscopic checklist is 1 method to evaluate and assess resident efficiency and improvement during surgical training. Among residents participating in this study, we found statistically significant improvements in time for arthroscopic task completion. II.

    Assessment of the acute eye irritation potential is part of the international regulatory requirements for testing of chemicals. The objective of the CON4EI project was to develop tiered testing strategies for eye irritation assessment. A set of 80 reference chemicals (38 liquids and 42 solids) was tested with eight different methods. Here, the results obtained with the EpiOcular™ Eye Irritation Test (EIT), adopted as OECD TG 492, are shown. The primary aim of this study was to evaluate of the performance of the test method to discriminate between chemicals not requiring classification for serious eye damage/eye irritancy (No Category) and chemicals requiring classification and labelling. In addition, the predictive capacity in terms of in vivo drivers of classification (i.e. corneal opacity, conjunctival redness and persistence at day 21) was investigated. EpiOcular™ EIT achieved a sensitivity of 97%, a specificity of 87% and accuracy of 95% and also confirmed its excellent reproducibility (100%) from the original validation. The assay was applicable to all chemical categories tested in this project and its performance was not limited to the particular driver of the classification. In addition to the existing prediction model for dichotomous categorization, a new prediction model for Cat 1 is suggested. Copyright © 2017. Published by Elsevier Ltd.

    Monochromatic aberrations may influence the visual acuity of the eye. They are not stable and can be affected by different factors. The subject of the following paper is the dynamic investigation of the changes in wavefront aberration with accommodation. Dynamic measurement of higher and lower order aberrations was performed with a WASCA Wavefront Analyzer (Carl-Zeiss-Meditec) and a specially constructed target device for aligning objects in far and near distances on 25 subjects aged from 15 to 27 years old. Wavefront aberrations showed some significant changes in accommodation. In addition to the characteristic sphere reaction accompanying miosis and changes in horizontal prism (Z(1) (1)) in the sense of a convergence movement of the eyeball also occurred. Furthermore defocus rose (Z(2) (0)) and astigmatism (Z(2) (-2)) changed. In higher-order aberrations a decrease in coma-like Zernike polynomials (Z(3) (-1), Z(3) (1)) was found. The most obvious change appeared in spherical aberration (Z(4) (0)) which increased and changed from positive to negative. In addition the secondary astigmatism (Z(4) (-2)) and quadrafoil (Z(4) (4)) rise also increased. The total root mean square (RMS), as well as the higher-order aberrations (RMS-HO) significantly increased in accommodation which is associated with a theoretical reduction of visual acuity. An analysis of the influence of pupil size on aberrations showed significant increases in defocus, spherical aberration, quadrafoil, RMS and RMS HO by increasing pupil diameter. By accommodation-associated miosis, the growing aberrations are partially compensated by focusing on near objects. Temporal analysis of the accommodation process with dynamic wavefront analysis revealed significant delays in pupil response and changing of prism in relation to the sphere reaction. In accommodation to near objects a discrete time ahead of third order aberrations in relation to the sphere response was found. Using dynamic wavefront measurement

    The effects of dynamical diffraction in x-ray diffractive optics with large numerical aperture render the wavefront aberrations difficult to describe using the aberration polynomials, yet knowledge of them plays an important role in a vast variety of scientific problems ranging from optical testing to adaptive optics. Although the diffraction theory of optical aberrations was established decades ago, its application in the area of x-ray dynamical diffraction theory (DDT) is still lacking. Here, we conduct a theoretical study on the aberration properties of x-ray dynamical diffraction beams. By treating the modulus of the complex envelope as the amplitude weight function in the orthogonalization procedure, we generalize the nonrecursive matrix method for the determination of orthonormal aberration polynomials, wherein Zernike DDT and Legendre DDT polynomials are proposed. As an example, we investigate the aberration evolution inside a tilted multilayer Laue lens. The corresponding Legendre DDT polynomials are obtained numerically, which represent balanced aberrations yielding minimum variance of the classical aberrations of an anamorphic optical system. The balancing of classical aberrations and their standard deviations are discussed. We also present the Strehl ratio of the primary and secondary balanced aberrations.

    Abstract Background The checklist of Porifera of Greece was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species recorded from Greece. An updated checklist of Porifera was created on the basis of a list of the Aegean Demospongiae and Homoscleromorpha published one decade ago. All records of species known to occur in Greek waters were taxonomically validated and cross-checked for possible inaccuracies and omissions. Then, all recent publications were reviewed and the species recorded from 2006 to date were added to the list. New information The updated checklist of Porifera of Greece comprises 215 species, classified to 111 genera, 65 families, 24 orders, and 4 classes. In total, 34 new additions were made to the previous species list (8 Calcarea, 17 Demospongiae, 1 Hexactinellida, and 6 Homoscleromorpha) with Calcarea being listed for the first time from the area. The demosponge orders Poecilosclerida, Dictyoceratida, Tetractinellida, Haplosclerida, and Suberitida have the highest number of species covering 62% of the known Greek sponge species richness. It is worth mentioning that 8 species have been first described from Greek waters, 7 of which are considered endemic to this area. Our bibliographic overview also revealed knowledge gaps with regard to specific habitats typically rich in sponge diversity, and marine sectors of Greece. PMID:27932903

    Frontotemporal dementia (FTD) is characterized by a number of prominent behavioral changes. While FTD has been associated with the presence of aberrant or unusual sexual behaviors in a proportion of patients, few studies have formally investigated changes in sexual function in this disease. We aimed to systematically quantify changes in sexual behavior, including current symptoms and changes from prior diagnoses, in behavioral-variant (bvFTD) and semantic dementia (SD), compared to Alzheimer's disease (AD). Carers of 49 dementia patients (21 bvFTD, 11 SD, 17 AD) were interviewed using the Sexual Behavior and Intimacy Questionnaire (SIQ), a survey designed to assess changes in sexual function across multiple domains including initiating, level of affection, and aberrant or unusual sexual behavior. BvFTD patients show prominent hyposexual behavior including decreased affection, initiation, and response to advances by partners, and decreased frequency of sexual relations, compared to AD and to SD patients. The greatest changes in sexual behavior compared to pre-diagnoses were found in the bvFTD group with a 90-100% decrease in initiation, response, and frequency of sexual relations. Notably, aberrant or unusual sexual behavior was reported in a minority of bvFTD and SD patients and occurred in patients who also showed hyposexual behavior toward their partner. Overall loss of affection, reduced initiation of sexual activity, and responsiveness is an overwhelming feature of bvFTD. In contrast, aberrant or unusual sexual behavior is observed in the minority of bvFTD patients. The underlying pathophysiology of these changes likely reflects structural and functional changes in frontoinsular and limbic regions including the hypothalamus.

    The objective of our study was to investigate the tandem irritation potential of two organic solvents with concurrent exposure to the hydrophilic detergent irritant sodium lauryl sulphate (SLS). A tandem repeated irritation test was performed with two undiluted organic solvents, cumene (C) and octane (O), with either alternating application with SLS 0.5% or twice daily application of each irritant alone in 27 volunteers on the skin of the back. The cumulative irritation induced over 4 days was quantified using visual scoring and non-invasive bioengineering measurements (skin colour reflectance, skin hydration and transepidermal water loss). Repeated application of C/SLS and O/SLS induced more decline of stratum corneum hydration and higher degrees of clinical irritation and erythema compared to each irritant alone. Our results demonstrate a further example of additive harmful skin effects induced by particular skin irritants and indicate that exposure to organic solvents together with detergents may increase the risk of acquiring occupational contact dermatitis. © 2014 S.

    2009-04-01

    The use of checklists is a promising strategy for improving patient safety in all types of surgical processes inside and outside the operating room. This article aims to provide requirements and implementation of checklists for surgical processes. The literature on checklist use in the operating room was reviewed based on research using Medline, Pubmed, and Google Scholar. Although all the studies showed positive effects and important benefits such as improved team cohesion, improved awareness of safety issues, and reduction of errors, their number still is limited. The motivation of team members is considered essential for compliance. Currently, no general guidelines exist for checklist design in the surgical field. Based on the authors' experiences and on guidelines used in the aviation industry, requirements for the checklist design are proposed. The design depends on the checklist purpose, philosophy, and method chosen. The methods consist of the "call-do-response" approach," the "do-verify" approach, or a combination of both. The advantages and disadvantages of paper versus electronic solutions are discussed. Furthermore, a step-by-step strategy of how to implement a checklist in the clinical situation is suggested. The use of structured checklists in surgical processes is most likely to be effective because it standardizes human performance and ensures that procedures are followed correctly instead of relying on human memory alone. Several studies present promising and positive first results, providing a solid basis for further investigation. Future research should focus on the effect of various checklist designs and strategies to ensure maximal compliance.

  4. On the Definition of Aberration

    2014-12-01

    There was a groundbreaking step in the history of astronomy in 1728 when the effect of aberration was discovered by James Bradley (1693-1762). Recently, the solar acceleration, due to the variations in the aberrational effect of extragalactic sources caused by it, has been determined from VLBI observations with an uncertainty of about 0.5 mm{\\cdot}{s^{-1}}{\\cdot}{yr^{-1}} level. As a basic concept in astrometry with a nearly 300-year history, the definition of aberration, however, is still equivocal and discordant in the literature. It has been under continuing debate whether it depends on the relative motion between the observer and the observed source or only on the motion of the observer with respect to the frame of reference. In this paper, we will review the debate and the inconsistency in the definition of the aberration since the last century, and then discuss its definition in detail, which involves the discussions on the planetary aberration, the stellar aberration, the proper motion of an object during the travel time of light from the object to the observer, and the way of selecting the reference frame to express and distinguish the motions of the source and the observer. The aberration is essentially caused by the transformation between coordinate systems, and consequently quantified by the velocity of the observer with respect to the selected reference frame, independent of the motion of the source. Obviously, this nature is totally different from that of the definition given by the IAU WG NFA (Capitaine, 2007) in 2006, which is stated as, ``the apparent angular displacement of the observed position of a celestial object from its geometric position, caused by the finite velocity of light in combination with the motions of the observer and of the observed object.''

    A quick-look Human Factors (HF) Checklist condenses industry and NASA Agency standards consisting of thousands of requirements into 14 main categories. With support from contractor HF and Safety Practitioners, NASA developed a means to share key HF messages with Design, Engineering, Safety, Project Management, and others. It is often difficult to complete timely assessments due to the large volume of HF information. The HF Checklist evolved over time into a simple way to consider the most important concepts. A wide audience can apply the checklist early in design or through planning phases, even before hardware or processes are finalized or implemented. The checklist is a good place to start to supplement formal HF evaluation. The HF Checklist was based on many Space Shuttle processing experiences and lessons learned. It is now being applied to ground processing of new space vehicles and adjusted for new facilities and systems.

    Background Although irritability is a core symptom of DSM-IV major depressive disorder (MDD) for youth but not adults, clinical studies find comparable rates of irritability between nonbipolar depressed adults and youth. Including irritability as a core symptom of adult MDD would allow detection of depression-equivalent syndromes with primary irritability hypothesized to be more common among males than females. We carried out a preliminary examination of this issue using cross-national community-based survey data from 21 countries in the World Mental Health (WMH) Surveys (n = 110,729). Methods The assessment of MDD in the WHO Composite International Diagnostic Interview includes one question about persistent irritability. We examined two expansions of the definition of MDD involving this question: (1) cases with dysphoria and/or anhedonia and exactly four of nine Criterion A symptoms plus irritability; and (2) cases with two or more weeks of irritability plus four or more other Criterion A MDD symptoms in the absence of dysphoria or anhedonia. Results Adding irritability as a tenth Criterion A symptom increased lifetime prevalence by 0.4% (from 11.2 to 11.6%). Adding episodes of persistent irritability increased prevalence by an additional 0.2%. Proportional prevalence increases were significantly higher, but nonetheless small, among males compared to females. Rates of severe role impairment were significantly lower among respondents with this irritable depression who did not meet conventional DSM-IV criteria than those with DSM-IV MDD. Conclusion Although limited by the superficial assessment in this single question on irritability, results do not support expanding adult MDD criteria to include irritable mood. PMID:23364997

  9. Effect of monochromatic aberrations on photorefractive patterns

    NASA Astrophysics Data System (ADS)

    1995-08-01

    Photorefractive methods have become popular in the measurement of refractive and accommodative states of infants and children owing to their photographic nature and rapid speed of measurement. As in the case of any method that measures the refractive state of the human eye, monochromatic aberrations will reduce the accuracy of the measurement. Monochromatic aberrations cannot be as easily predicted or controlled as chromatic aberrations during the measurement, and accordingly they will introduce measurement errors. This study defines this error or uncertainty by extending the existing paraxial optical analyses of coaxial and eccentric photorefraction. This new optical analysis predicts that, for the amounts of spherical aberration (SA) reported for the human eye, there will be a significant degree of measurement uncertainty introduced for all photorefractive methods. The dioptric amount of this uncertainty may exceed the maximum amount of SA present in the eye. The calculated effects on photorefractive measurement of a real eye with a mixture of spherical aberration and coma are shown to be significant. The ability, developed here, to predict photorefractive patterns corresponding to different amounts and types of monochromatic aberration may in the future lead to an extension of photorefractive methods to the dual measurement of refractive states and aberrations of individual eyes. aberration, retinal image quality,

    Assessment of ocular irritancy is an international regulatory requirement in the safety evaluation of industrial and consumer products. Although many in vitro ocular irritation assays exist, alone they are incapable of fully categorizing chemicals. The objective of CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project was to develop tiered testing strategies for eye irritation assessment that can lead to complete replacement of the in vivo Draize rabbit eye test (OECD TG 405). A set of 80 reference chemicals was tested with seven test methods, one method was the Slug Mucosal Irritation (SMI) test method. The method measures the amount of mucus produced (MP) during a single 1-hour contact with a 1% and 10% dilution of the chemical. Based on the total MP, a classification (Cat 1, Cat 2, or No Cat) is predicted. The SMI test method correctly identified 65.8% of the Cat 1 chemicals with a specificity of 90.5% (low over-prediction rate for in vivo Cat 2 and No Cat chemicals). Mispredictions were predominantly unidirectional towards lower classifications with 26.7% of the liquids and 40% of the solids being underpredicted. In general, the performance was better for liquids than for solids with respectively 76.5% vs 57.1% (Cat 1), 61.5% vs 50% (Cat 2), and 87.5% vs 85.7% (No Cat) being identified correctly.

  11. From railway spine to whiplash--the recycling of nervous irritation.

    2003-11-01

    The search for a specific structural basis for chronic whiplash and other chronic pain and fatigue syndromes has been in progress for decades, and yet currently there remains no "structural" solution to these enigmata. In light of the failure of research to identify the chronic "damage" or pathology as lying in a muscular, bony, or "connective tissue" sites for many chronic pain syndromes like whiplash, fibromyalgia, et cetera, more recent attention has been paid to nervous system structures. Nerve irritation has been implicated as the basis for the pain and other symptoms that are common to many chronic disability syndromes. We postulate here, however, that the concept of nervous irritation has been prostituted for centuries whenever more concrete structural explanations for chronic pain and other controversial illness have been untenable. We suggest that, after each cycle of nervous irritation as a disease, and subsequent dismissal of the notion, the doctrine of irritation as a disease was too good to go away. First, with the hypersthenic and asthenic diseases of the nineteenth century, then railway spine, whiplash, thoracic outlet syndrome, and now brachial plexus irritation, we detect the same pattern: patients with symptoms, but no objective evidence of nerve disease. Nervous irritation has repeatedly served this purpose for the last 200 years. It is our intent that bringing an understanding of this trend will encourage current clinicians and researchers to appreciate the need to abandon this form of speculation without historical insight when dealing with today's controversial syndromes.

VCZ loaded microemulsion could be an effective strategy for efficient ocular delivery of the drug. To perform corneal irritation studies and in vivo delivery of VCZ microemulsion to establish its potential as an efficient ocular delivery system. Ocular irritancy was performed by HETCAM (Hen's Egg Test Chorio Allantoic Membrane) assay, corneal histopathology and Draize test. Ex vivo and in vivo studies were performed to determine permeation efficiency of VCZ microemulsion. The irritation studies suggested the non-irritant nature of the microemulsion. The ex vivo studies performed on excised cornea displayed significant enhancement in drug permeation/penetration from microemulsion in contrast to the drug suspension. Further, the in vivo study confirmed the higher availability of VCZ (from microemulsion) in aqueous humor with minimal nasolacrimal drainage (lower plasma drug content) when compared with the drug suspension. The non-irritant nature and high corneal permeation of VCZ encourages the role of microemulsion as a potential ocular delivery system.

    Irritable bowel syndrome is a disease process commonly encountered by primary care providers. Although the cause of this illness is unknown, much is known about the pathophysiology and strong psychosocial influences. Medical practitioners often are aware of the medical aspects of managing irritable bowel syndrome but are not familiar with specific psychologic options. Long-term care of these patients may be aided by collaboration with mental health professionals.

    Capsaicin, a topical analgesic used in the treatment of chronic pain, has irritant properties that frequently interrupt its use. In this work, the effect of nanoencapsulation of the main capsaicinoids (capsaicin and dihydrocapsaicin) on skin irritation was tested in humans. Skin tolerance of a novel vehicle composed of chitosan hydrogel containing nonloaded nanocapsules (CH-NC) was also evaluated. The chitosan hydrogel containing nanoencapsulated capsaicinoids (CH-NC-CP) did not cause skin irritation, as measured by an erythema probe and on a visual scale, while a formulation containing free capsaicinoids (chitosan gel with hydroalcoholic solution [CH-ET-CP]) and a commercially available capsaicinoids formulation caused skin irritation. Thirty-one percent of volunteers reported slight irritation one hour after application of CH-NC-CP, while moderate (46% [CH-ET-CP] and 23% [commercial product]) and severe (8% [CH-ET-CP] and 69% [commercial product]) irritation were described for the formulations containing free capsaicinoids. When CH-NC was applied to the skin, erythema was not observed and only 8% of volunteers felt slight irritation, which demonstrates the utility of the novel vehicle. A complementary in vitro skin permeation study showed that permeation of capsaicinoids through an epidermal human membrane was reduced but not prevented by nanoencapsulation. PMID:24611011

    Best supportive care (BSC) is often not standardized across sites, consistent with best evidence, or sufficiently described. We developed a consensus-based checklist to document BSC delivery, including symptom management, decision making, and care planning. We hypothesized that BSC can be feasibly documented with this checklist consistent with consolidated standards of reporting trials. To determine feasibility/acceptability of a BSC checklist among clinicians. To test feasibility of a BSC checklist in standard care, we enrolled a sample of clinicians treating patients with advanced cancer at four centers. Clinicians were asked to complete the checklist at eligible patient encounters. We surveyed enrollees regarding checklist use generating descriptive statistics and frequencies. We surveyed 15 clinicians and 9 advanced practice providers. Mean age was 41 (SD = 7.9). Mean years since fellowship for physicians was 7.2 (SD = 4.5). Represented specialties are medical oncology (n = 8), gynecologic oncology (n = 4), palliative care (n = 2), and other (n = 1). For "overall impact on your delivery of supportive/palliative care," 40% noted improved impact with using BSC. For "overall impact on your documentation of supportive/palliative care," 46% noted improvement. Impact on "frequency of comprehensive symptom assessment" was noted to be "increased" by 33% of providers. None noted decreased frequency or worsening impact on any measure with use of BSC. Regarding feasibility of integrating the checklist into workflow, 73% agreed/strongly agreed that checklists could be easily integrated, 73% saw value in integration, and 80% found it easy to use. Clinicians viewed the BSC checklist favorably illustrating proof of concept, minor workflow impact, and potential of benefit to patients.

    Peer review is widely considered fundamental to maintaining the rigour of science, but it often fails to ensure transparency and reduce bias in published papers, and this systematically weakens the quality of published inferences. In part, this is because many reviewers are unaware of important questions to ask with respect to the soundness of the design and analyses, and the presentation of the methods and results; also some reviewers may expect others to be responsible for these tasks. We therefore present a reviewers' checklist of ten questions that address these critical components. Checklists are commonly used by practitioners of other complex tasks, and we see great potential for the wider adoption of checklists for peer review, especially to reduce bias and facilitate transparency in published papers. We expect that such checklists will be well received by many reviewers.

    Abstract Background The checklist of Greek Cyanobacteria was created in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research Infrastructure (ESFRI) that has resumed efforts to compile a complete checklist of species reported from Greece. This list was created from exhaustive search of the scientific literature of the last 60 years. All records of taxa known to occur in Greece were taxonomically updated. New information The checklist of Greek Cyanobacteria comprises 543 species, classified in 130 genera, 41 families, and 8 orders. The orders Synechococcales and Oscillatoriales have the highest number of species (158 and 153 species, respectively), whereas these two orders along with Nostocales and Chroococcales cover 93% of the known Greek cyanobacteria species. It is worth mentioning that 18 species have been initially described from Greek habitats. The marine epilithic Ammatoidea aegea described from Saronikos Gulf is considered endemic to this area. Our bibliographic review shows that Greece hosts a high diversity of cyanobacteria, suggesting that the Mediterranean area is also a hot spot for microbes. PMID:27956851

    The WHO has designed a safe surgery checklist to enhance communication and awareness of patient safety during surgery and to minimise complications. WHO recommends that the check-list be evaluated and customised by end users as a tool to promote safe surgery. The aim of present study was to evaluate the impact of WHO safety checklist on patient safety awareness in otorhinolaryngology and to customise it for the speciality. A prospective structured questionnaire based study was done in ENT operating room for duration of 1 month each for cases, before and after implementation of safe surgery checklist. The feedback from respondents (surgeons, nurses and anaesthetists) was used to arrive at a customised checklist for otolaryngology as per WHO guidelines. The checklist significantly improved team member's awareness of patient's identity (from 17 to 86%) and each other's identity and roles (from 46 to 94%) and improved team communication (from 73 to 92%) in operation theatre. There was a significant improvement in preoperative check of equipment and critical events were discussed more frequently. The checklist could be effectively customised to suit otolaryngology needs as per WHO guidelines. The modified checklist needs to be validated by otolaryngology associations. We conclude from our study that the WHO Surgical safety check-list has a favourable impact on patient safety awareness, team-work and communication of operating team and can be customised for otolaryngology setting.

    This presentation will discuss the design, implementation, and evaluation of a competency-based checklist in military nursing network. The checklist was initiated to help assess case manager competency where background and preparation for the case manager role were quite diverse. The checklist assisted initially with the assessment of learning needs; later, it served as a self-assessment for case managers to determine their areas for improvement. Finally, the assessment was used not only to verify competency by the case management supervisor, but also to establish systemwide quality in case management.

  1. Checklist and "Pollard Walk" butterfly survey methods on public lands

    1998-01-01

    Checklist and “Pollard Walk” butterfly survey methods were contemporaneously applied to seven public sites in North Dakota during the summer of 1995. Results were compared for effect of method and site on total number of butterflies and total number of species detected per hour. Checklist searching produced significantly more butterfly detections per hour than Pollard Walks at all sites. Number of species detected per hour did not differ significantly either among sites or between methods. Many species were detected by only one method, and at most sites generalist and invader species were more likely to be observed during checklist searches than during Pollard Walks. Results indicate that checklist surveys are a more efficient means for initial determination of a species list for a site, whereas for long-term monitoring the Pollard Walk is more practical and statistically manageable. Pollard Walk transects are thus recommended once a prairie butterfly fauna has been defined for a site by checklist surveys.

    The WHO Safe Childbirth Checklist (SCC) was developed to ensure the delivery of essential maternal and perinatal care practices around the time of childbirth. A research collaboration was subsequently established to explore factors that influence use of the Checklist in a range of settings around the world. This analysis article presents an overview of the WHO SCC Collaboration and the lessons garnered from implementing the Checklist across a diverse range of settings. Project leads from each collaboration site were asked to distribute two surveys. The first was given to end users, and the second to implementation teams to describe their respective experiences using the Checklist. A total of 134 end users and 38 implementation teams responded to the surveys, from 19 countries across all levels of income. End users were willing to adopt the SCC and found it easy to use. Training and the provision of supervision while using the Checklist, alongside leadership engagement and local ownership, were important factors which helped facilitate initial implementation and successful uptake of the Checklist. Teams identified several challenges, but more importantly successfully implemented the WHO SCC. A critical step in all settings was the adaptation of the Checklist to reflect local context and national protocols and standards. These findings were invaluable in developing the final version of the WHO SCC and its associated implementation guide. Our experience will provide useful insights for any institution wishing to implement the Checklist. PMID:29082003

    Although the child behavior checklist (CBCL) and the teacher's report form (TRF) were not designed for diagnosing psychopathology in children with chronic illnesses, they have become extensively used research tools to assess behavioural problems in paediatric populations, including children with epilepsy. When applied to children with epilepsy, items like "staring blankly" or "twitching" can be rated on the basis of seizure features rather than behaviour and, hence, render behavioural scores ambiguous. The aims were detection, and evaluation of the impact, of CBCL and TRF items eliciting ambiguity when applied to children with "epilepsy only" (idiopathic or cryptogenic epilepsy, attending normal schools). Experts identified items that give rise to interpretational ambiguity of the ratings in epilepsy. By treating ratings on these items as missing values, their effect was evaluated in CBCL and TRF scores of 59 schoolchildren with "epilepsy only" and age and gender matched healthy classmates. Seven items of the CBCL gave rise to ambiguity of which items 5 co-occur on the TRF. Rescoring reduced psychopathology scores in children with "epilepsy only", but not in those of healthy children: the percentage of patients trespassing the clinical cut off score, on at least one of the subscales, reduced from 46 to 23% on the CBCL and from 18 to 15% on the TRF. Parents and teachers run the risk of confusing behaviour and seizure features when filling out the CBCL and TRF. In "epilepsy only", prevalence estimates of psychopathology based on the CBCL and TRF, should be considered with some reserve.

    The general equations for the point-spread function (PSF) and optical transfer function (OTF) are given for any pupil shape, and they are applied to optical imaging systems with circular and annular pupils. The symmetry properties of the PSF, the real and imaginary parts of the OTF, and the modulation transfer function (MTF) of a system with a circular pupil aberrated by a Zernike circle polynomial aberration are derived. The interferograms and PSFs are illustrated for some typical polynomial aberrations with a sigma value of one wave, and 3D PSFs and MTFs are shown for 0.1 wave. The Strehl ratio is also calculated for polynomial aberrations with a sigma value of 0.1 wave, and shown to be well estimated from the sigma value. The numerical results are compared with the corresponding results in the literature. Because of the same angular dependence of the corresponding annular and circle polynomial aberrations, the symmetry properties of systems with annular pupils aberrated by an annular polynomial aberration are the same as those for a circular pupil aberrated by a corresponding circle polynomial aberration. They are also illustrated with numerical examples.

    Purpose To find out the mean corneal spherical aberration and its changes with age in Saudi population. Setting AlHokama Eye Specialist Center, Riyadh, Saudi Arabia. Methods Three hundred (300) eyes of 185 Saudi subjects (97 men and 88 women), whose age ranged from 15 to 85 years old, with matched refractive errors, were divided into three groups according to their age, 100 for each. All the subjects were included in measuring the spherical aberration (SA) using pentacam HR (OCULUS, Germany) at the 6-mm optical zone. Results The mean corneal spherical aberration (CSA) of the fourth order (Z40) of the whole groups was 0.252 ± 0.1154 μm. Patients from 15 to 35 years old have root mean square (RMS) of CSA of 0.2068 ± 0.07151 μm, 0.2370 ± 0.08023 μm was the RMS of CSA of the patients from 35 to 50 years old, while those from 50 to 85 years old have a CSA-RMS of 0.31511 ± 0.1503 μm (P < 0.0001). A positive correlation was found between the spherical aberration (Z40) and the progress of age (r = 0.3429, P < 0.0001). The high order aberration (HOA) presented 28.1% of the total corneal aberrations. While the fourth order corneal spherical aberration constituted 57% of the HOA and 16% of the total aberration. The pupil diameter shows a negative correlation with the increase in age (P = 0.0012). Conclusion Our results showed a CSA (Z40) that is varied among the population, comparable to other studies, and significantly correlates to the progress of age. PMID:25278799

    The purpose of this study was to develop a checklist of items that describes and measures the quality of reports of interventional trials assessing spa therapy. The Delphi consensus method was used to select the number of items in the checklist. A total of eight individuals participated, including an epidemiologist, a clinical research methodologist, clinical researchers, a medical journalist, and a health fitness programmer. Participants ranked on a 9-point Likert scale whether an item should be included in the checklist. Three rounds of the Delphi method were conducted to achieve consensus. The final checklist contained 19 items, with items related to title, place of implementation (specificity of spa), care provider influence, and additional measures to minimize the potential bias from withdrawals, loss to follow-up, and low treatment adherence. This checklist is simple and quick to complete, and should help clinicians and researchers critically appraise the medical and healthcare literature, reviewers assess the quality of reports included in systematic reviews, and researchers plan interventional trials of spa therapy.

    Purpose: Transcranial magnetic resonance-guided focused ultrasound surgery is a noninvasive technique for causing selective tissue necrosis. Variations in density, thickness, and shape of the skull cause aberrations in the location and shape of the focal zone. In this paper, the authors propose a hybrid simulation-MR-ARFI technique to achieve aberration correction for transcranial MR-guided focused ultrasound surgery. The technique uses ultrasound beam propagation simulations with MR Acoustic Radiation Force Imaging (MR-ARFI) to correct skull-caused phase aberrations. Methods: Skull-based numerical aberrations were obtained from a MR-guided focused ultrasound patient treatment and were added to all elements of the InSightec conformal bone focusedmore » ultrasound surgery transducer during transmission. In the first experiment, the 1024 aberrations derived from a human skull were condensed into 16 aberrations by averaging over the transducer area of 64 elements. In the second experiment, all 1024 aberrations were applied to the transducer. The aberrated MR-ARFI images were used in the hybrid simulation-MR-ARFI technique to find 16 estimated aberrations. These estimated aberrations were subtracted from the original aberrations to result in the corrected images. Each aberration experiment (16-aberration and 1024-aberration) was repeated three times. Results: The corrected MR-ARFI image was compared to the aberrated image and the ideal image (image with zero aberrations) for each experiment. The hybrid simulation-MR-ARFI technique resulted in an average increase in focal MR-ARFI phase of 44% for the 16-aberration case and 52% for the 1024-aberration case, and recovered 83% and 39% of the ideal MR-ARFI phase for the 16-aberrations and 1024-aberration case, respectively. Conclusions: Using one MR-ARFI image and noa priori information about the applied phase aberrations, the hybrid simulation-MR-ARFI technique improved the maximum MR-ARFI phase of the beam's focus.« less

    An in-flight smoke or fire event is an emergency unlike almost any other. The early cues for un-alerted conditions, such as air conditioning smoke or fire, are often ambiguous and elusive. The checklists crews use for these conditions must help them respond quickly and effectively and must guide their decisions. Ten years ago an industry committee developed a template to guide the content of Part 121 checklists for un-alerted smoke and fire events. This template is based upon a new philosophy about how crews should use the checklists and respond to the events. To determine the degree to which current un-alerted checklists of in-flight smoke or fire comply or are consistent with the guidance outlined in the template, I collected and analysed checklists from North American air carriers.

    Glycerol is known to possess anti-irritant and hydrating properties and previous studies suggested that xylitol may also have similar effects. Our aim was to study whether different concentrations of these polyols restore skin barrier function and soothe inflammation in sodium lauryl sulphate (SLS)-induced acute irritation. The experiments were performed on male SKH-1 hairless mice. The skin of the dorsal region was exposed to SLS (5%) for 3 h alone or together with 5% or 10% of glycerol respectively. Further two groups received xylitol solutions (8.26% and 16.52% respectively) using the same osmolarities, which were equivalent to those of the glycerol treatments. The control group was treated with purified water. Transepidermal water loss (TEWL) and skin hydration were determined. Microcirculatory parameters of inflammation were observed by means of intravital videomicroscopy (IVM). Furthermore, accumulation of neutrophil granulocytes and lymphocytes, the expression of inflammatory cytokines and SLS penetration were assessed, as well. Treatment with the 10% of glycerol and both concentrations of xylitol inhibited the SLS-induced elevation of TEWL and moderated the irritant-induced increase in dermal blood flow and in the number of leucocyte-endothelial interactions. All concentrations of the applied polyols improved hydration and prevented the accumulation of lymphocytes near the treatment site. At the mRNA level, neither glycerol nor xylitol influenced the expression of interleukin-1 alpha. However, expression of interleukin-1 beta was significantly decreased by the 10% glycerol treatment, while expression of tumour necrosis factor-alpha decreased upon the same treatment, as well as in response to xylitol. Higher polyol treatments decreased the SLS penetration to the deeper layers of the stratum corneum. Both of the analysed polyols exert considerable anti-irritant and anti-inflammatory properties, but the effective concentration of xylitol is lower than that of

    The current work builds a definition of irritability from both academic definitions and lay perspectives. In Study 1, a quantitative content analysis of academic definitions resulted in eight main content categories (i.e., behaviour, emotion or affect, cognition, physiological, qualifiers, irritant, stability or endurance, and other). In Study 2, a community sample of 39 adults participated in qualitative interviews. A deductive thematic analysis resulted in two main themes. The first main theme dealt with how participants positioned irritability in relation to other negative states. The second dealt with how participants constructed irritability as both a loss of control and as an experience that should be controlled. The discussion integrates the findings of both studies and provides a concise, but comprehensive definition.

    Ibuprofen is a commonly used non-steroidal anti-inflammatory drug administered to treat injuries, joint pain, and recurrent muscular skeletal pain. The aim of this study was to determine the cutaneous irritancy of a medicated ibuprofen plaster compared with a placebo plaster in healthy volunteers. Healthy volunteers (N = 31) were treated at the same time with one ibuprofen and one placebo plaster. The ibuprofen and placebo plaster were applied in a randomized fashion to sites on the left or right side of subjects' lower backs. At each scheduled visit, the plasters and applications sites were assessed for degree of adhesion and skin irritancy, respectively. The plasters were applied on study Days 1, 2, 3, 5, 8, 10, 12, 15, 17, and 19, with final plaster removal on Day 22. The ibuprofen medicated plaster compared with placebo had a lower percentage of Grade 1 (23.3% vs. 46.7%, respectively), Grade 2 (10% vs. 20%), and ≥Grade 3 (3% vs. 16.1%) irritancy scores after 21 days of application. The mean irritation score across the study was 0.40 for the ibuprofen medicated plaster and 1.18 for the placebo plaster. The irritation score on Day 22 of the study was 0.53 for the ibuprofen medicated plaster and 1.50 for placebo. The placebo plaster was associated with a higher number of stopped applications due to Grade 3 or above skin reactions compared with the ibuprofen medicated plaster (5 vs. 1, respectively). The ibuprofen medicated plaster was well tolerated and was associated with lower irritancy than the placebo plaster.

    To design and establish content and face validity of an evidence-informed tool that promotes parental self-reflection during the transition to parenthood. The New Parent Checklist was developed using a three-phase sequential approach: Phase 1 a scoping review and expert consultation to develop and refine a prototype tool; Phase 2 content analysis of parent focus groups; and Phase 3 assessment of utility in a cross-sectional sample of parents completing the New Parent Checklist and a questionnaire. The initial version of the checklist was considered by experts to contain key information. Focus group participants found it useful, appropriate, and nonjudgmental, and offered suggestions to enhance readability, utility, as well as face and content validity. In the cross-sectional survey, 83% of the participants rated the New Parent Checklist as "helpful" or "very helpful" and 90% found the New Parent Checklist "very easy" to use. Open-ended survey responses included predominantly positive feedback. Notable differences existed for some items based on respondents' first language, age, and sex. Results and feedback from all three phases informed the current version, available for download online. The New Parent Checklist is a comprehensive evidence-informed self-reflective tool with promising content and face validity. Depending on parental characteristics and infant age, certain items of the New Parent Checklist have particular utility but may also require further adaptation and testing. Local resources for information and/or support are included in the tool and could be easily adapted by other regions to incorporate their own local resources.

  15. Anti-forensics of chromatic aberration

    Mayer, Owen; Stamm, Matthew C.

    2015-03-01

    Over the past decade, a number of information forensic techniques have been developed to identify digital image manipulation and falsification. Recent research has shown, however, that an intelligent forger can use anti-forensic countermeasures to disguise their forgeries. In this paper, an anti-forensic technique is proposed to falsify the lateral chromatic aberration present in a digital image. Lateral chromatic aberration corresponds to the relative contraction or expansion between an image's color channels that occurs due to a lens's inability to focus all wavelengths of light on the same point. Previous work has used localized inconsistencies in an image's chromatic aberration to expose cut-and-paste image forgeries. The anti-forensic technique presented in this paper operates by estimating the expected lateral chromatic aberration at an image location, then removing deviations from this estimate caused by tampering or falsification. Experimental results are presented that demonstrate that our anti-forensic technique can be used to effectively disguise evidence of an image forgery.

  16. A Evaluation of Optical Aberrations in Underwater Hologrammetry

    NASA Astrophysics Data System (ADS)

    Kilpatrick, J. M.

    Available from UMI in association with The British Library. An iterative ray-trace procedure is developed in conjunction with semi-analytic expressions for spherical aberration, coma, and astigmatism in the reconstructed holographic images of underwater objects. An exact expression for the astigmatic difference is obtained, based on the geometry of the caustic for refraction. The geometrical characteristics of the aberrated images associated with axial and non-axial field positions are represented by ray intersection diagrams. A third order expression for the wavefront aberration introduced at a planar air/water boundary is given. The associated third order aberration coefficients are used to obtain analytic expressions for the aberrations observed in underwater hologrammetry. The results of the third order treatment are shown to give good agreement with the results obtained by geometrical ray tracing and by direct measurement on the reconstructed real image. The third order aberration coefficients are employed to estimate the limit of resolution in the presence of the aberrations associated with reconstruction in air. In concurrence with practical observations it is found that the estimated resolution is primarily limited by astigmatism. The limitations of the planar window in underwater imaging applications are outlined and various schemes are considered to effect a reduction in the extent of aberration. The analogous problems encountered in underwater photography are examined in order to establish the grounds for a common solution based on a conventional optical corrector. The performance of one such system, the Ivanoff Corrector, is investigated. The spherical aberration associated with axial image formation is evaluated. The equivalence of the third order wavefront aberration introduced at a planar air/water boundary to that introduced upon reconstruction by an appropriate wavelength change is shown to provide a basis for the compensation of aberrations in

    Little is known about cytokines involved in chronic irritant contact dermatitis. Individual cytokine profiles might explain at least part of the differences in the individual response to irritation. Our objective was to investigate the relation between baseline stratum corneum (SC) cytokine levels and the skin response to a single and a repeated irritation test. This study also aimed to determine changes in SC cytokine levels after repeated irritation. Transepidermal water loss (TEWL) and erythema were measured in 20 volunteers after single 24-hr exposure to 1% sodium lauryl sulfate (SLS), and during and after repeated exposure to 0.1% SLS over a 3-week period. SC cytokine levels were measured from an unexposed skin site and from the repeatedly exposed site. Interleukin (IL)-1alpha decreased by 30% after repeated exposure, while IL-1RA increased 10-fold and IL-8 increased fourfold. Baseline IL-1RA and IL-8 values were predictors of TEWL and erythema after single exposure (r = 0.55-0.61). 6 subjects showed barrier recovery during repeated exposure. Baseline IL-1RA and IL-8 levels are likely to be indicators of higher skin irritability after single exposure to SLS. Barrier repair in some of the subjects might explain the lack of agreement between the TEWL response after single and repeated irritation.

    The present study’s objective was to determine the mechanisms for enhancing the utility of action checklists applied in participatory approach programs for workplace improvements, to identify the benefits of building consensus and to compare their applicability in Asian countries to find the most appropriate configuration for action checklists. Data were collected from eight trainees and 43 trainers with experience in Participatory Action-Oriented Training. Statistical analysis was performed in SPSS using the package PASW, version 19.0. The difference in the mean score for the degree of the utility of action checklists between countries was analyzed using ANOVA methods. Factor analysis was performed to validate the action checklists’ utility. Pearson Correlation Coefficients were then calculated to determine the direction and strength of the relationship between these factors. Using responses obtained from trainees’ in-depth interviews, we identified 33 key statements that were then classified into 11 thematic clusters. Five factors were extracted, namely “ease of application”, “practical solutions”, “group interaction”, “multifaceted perspective” and “active involvement”. The action checklist was useful for facilitating a participatory process among trainees and trainers for improving working conditions. Action checklists showed similar patterns of utility in various Asian countries; particularly when adjusted to local conditions. PMID:25224334

    OBJECT Approximately 250 million surgical procedures are performed annually worldwide, and data suggest that major complications occur in 3%-17% of them. Many of these complications can be classified as avoidable, and previous studies have demonstrated that preoperative checklists improve operating room teamwork and decrease complication rates. Although the authors' institution has instituted a general preoperative "time-out" designed to streamline communication, flatten vertical authority gradients, and decrease procedural errors, there is no specific checklist for transnasal transsphenoidal anterior skull base surgery, with or without endoscopy. Such minimally invasive cranial surgery uses a completely different conceptual approach, set-up, instrumentation, and operative procedure. Therefore, it can be associated with different types of complications as compared with open cranial surgery. The authors hypothesized that a detailed, procedure-specific, preoperative checklist would be useful to reduce errors, improve outcomes, decrease delays, and maximize both teambuilding and operational efficiency. Thus, the object of this study was to develop such a checklist for endonasal transsphenoidal anterior skull base surgery. METHODS An expert panel was convened that consisted of all members of the typical surgical team for transsphenoidal endoscopic cases: neurosurgeons, anesthesiologists, circulating nurses, scrub technicians, surgical operations managers, and technical assistants. Beginning with a general checklist, procedure-specific items were added and categorized into 4 pauses: Anesthesia Pause, Surgical Pause, Equipment Pause, and Closure Pause. RESULTS The final endonasal transsphenoidal anterior skull base surgery checklist is composed of the following 4 pauses. The Anesthesia Pause consists of patient identification, diagnosis, pertinent laboratory studies, medications, surgical preparation, patient positioning, intravenous/arterial access, fluid management

  2. Administration of Lactobacillus helveticus NS8 improves behavioral, cognitive, and biochemical aberrations caused by chronic restraint stress.

    Increasing numbers of studies have suggested that the gut microbiota is involved in the pathophysiology of stress-related disorders. Chronic stress can cause behavioral, cognitive, biochemical, and gut microbiota aberrations. Gut bacteria can communicate with the host through the microbiota-gut-brain axis (which mainly includes the immune, neuroendocrine, and neural pathways) to influence brain and behavior. It is hypothesized that administration of probiotics can improve chronic-stress-induced depression. In order to examine this hypothesis, the chronic restraint stress depression model was established in this study. Adult specific pathogen free (SPF) Sprague-Dawley rats were subjected to 21 days of restraint stress followed by behavioral testing (including the sucrose preference test (SPT), elevated-plus maze test, open-field test (OFT), object recognition test (ORT), and object placement test (OPT)) and biochemical analysis. Supplemental Lactobacillus helveticus NS8 was provided every day during stress until the end of experiment, and selective serotonin reuptake inhibitor (SSRI) citalopram (CIT) served as a positive control. Results showed that L. helveticus NS8 improved chronic restraint stress-induced behavioral (anxiety and depression) and cognitive dysfunction, showing an effect similar to and better than that of CIT. L. helveticus NS8 also resulted in lower plasma corticosterone (CORT) and adrenocorticotropic hormone (ACTH) levels, higher plasma interleukin-10 (IL-10) levels, restored hippocampal serotonin (5-HT) and norepinephrine (NE) levels, and more hippocampal brain-derived neurotrophic factor (BDNF) mRNA expression than in chronic stress rats. Taken together, these results indicate an anti-depressant effect of L. helveticus NS8 in rats subjected to chronic restraint stress depression and that this effect could be due to the microbiota-gut-brain axis. They also suggest the therapeutic potential of L. helveticus NS8 in stress-related and possibly other

    Freeform surfaces have advantages on balancing asymmetric aberration of the unobscured push-broom imager. However, since the conventional paraxial aberration theory is no longer appropriate for the freeform system design, designers are lack of insights on the imaging quality from the freeform aberration distribution. In order to design the freeform optical system efficiently, the contribution and nodal behavior of coma and astigmatism introduced by Standard Zernike polynomial surface are discussed in detail. An unobscured three-mirror optical system with 850 mm effective focal length, 20°× 2° field of view (FOV) is designed. The coma and astigmatism nodal positions are moved into the real-FOV by selecting and optimizing the Zernike terms pointedly, which has balanced the off-axis asymmetric aberration. The results show that the modulation transfer function (MTF) is close to diffraction limit, and the distortion throughout full-FOV is less than 0.25%. At last, a computer-generated hologram (CGH) for freeform surface testing is designed. The CGH design error RMS is lower than λ/1000 at 632.8 nm, which meets the requirements for measurement.

    To assess the irritation and contact sensitization potential of a 200 mg ibuprofen medicated plaster. This double-blind, phase-1 placebo controlled study had two phases; the induction phase to evaluate the irritant potential of continuous application of the plaster, and the challenge phase to assess contact sensitivity (allergy). The cumulative irritancy potential was evaluated using an adaptation of the Shelanski method. Healthy adults (≥18 years of age) (N = 210) were treated simultaneously with one ibuprofen medicated and one placebo plaster applied in a randomized fashion to either the left or right side of the lower back. During the induction phase, plasters were applied on Days 1, 3, 5, 8, 10, 12, 15, 17, and 19 and the final plaster removed on Day 22. At each scheduled visit plasters and applications sites were assessed for degree of adhesion and skin irritation (score of 1 = no irritation to 7 = strong reaction spreading beyond test sites), respectively. The challenge phase followed a two-week washout period. A plaster was applied on Day 36 for 48 h and assessment occurred on Days 38, 39, and 40. The mean cumulative irritation score during the induction phase was lower for the ibuprofen medicated plaster than the placebo plaster (0.32 vs. 1.23, respectively). Three (1.4%) subjects experience a dermal reaction of grade ≥3 for the ibuprofen medicated plaster compared with 27 (12.7%) for the placebo plaster. Following challenge with ibuprofen or placebo plasters, 12 subjects (6.2%) with the ibuprofen medicated plaster and four (2.2%) with the placebo plaster had skin reaction of assessment grade higher than the induction phase. One subject for the ibuprofen and two for the placebo plaster had reactions with grade >2. No subjects showed an increase in sensitization on Day 39 or 40 compared with Day 38. The findings indicate that the both the irritancy and contact sensitization of the ibuprofen medicated plaster is acceptable.

    To develop a realistic model of the optomechanical behavior of the cornea after curved relaxing incisions to simulate the induced astigmatic change and predict the optical aberrations produced by the incisions. ICMA Consejo Superior de Investigaciones Científicas and Universidad de Zaragoza, Zaragoza, Spain. A 3-dimensional finite element model of the anterior hemisphere of the ocular surface was used. The corneal tissue was modeled as a quasi-incompressible, anisotropic hyperelastic constitutive behavior strongly dependent on the physiological collagen fibril distribution. Similar behaviors were assigned to the limbus and sclera. With this model, some corneal incisions were computer simulated after the Lindstrom nomogram. The resulting geometry of the biomechanical simulation was analyzed in the optical zone, and finite ray tracing was performed to compute refractive power and higher-order aberrations (HOAs). The finite-element simulation provided new geometry of the corneal surfaces, from which elevation topographies were obtained. The surgically induced astigmatism (SIA) of the simulated incisions according to the Lindstrom nomogram was computed by finite ray tracing. However, paraxial computations would yield slightly different results (undercorrection of astigmatism). In addition, arcuate incisions would induce significant amounts of HOAs. Finite-element models, together with finite ray-tracing computations, yielded realistic simulations of the biomechanical and optical changes induced by relaxing incisions. The model reproduced the SIA indicated by the Lindstrom nomogram for the simulated incisions and predicted a significant increase in optical aberrations induced by arcuate keratotomy.

    Patient safety is critical for the patients, providers, and risk managers in the office-based procedural setting, and the same standard of care should be maintained regardless of the healthcare environment. Checklists may improve patient safety and potentially decrease risk. This study explored utilization of checklists in the office-based setting and the potential barriers to their implementation. A cross-sectional prospective study was performed by using a 19-question anonymous survey designed with REDCap®. Medical providers including physicians and nurses from 25 different offices that performed procedures participated, and 38 individual responses were included in the study. Only 50% of offices surveyed use safety checklists in their practice. Only 34% had checklists or equivalent protocol for emergencies such as anaphylaxis or failed airway. As many as 23.7% of respondents indicated that they encountered barriers to implementing checklists. The top barriers identified in the study were no incentive to use a checklist (77.8%), no mandate from a local or federal regulatory agency (44.4%), being too time consuming (33.3%), and lack of training (33.3%). Reasons identified that would encourage providers to use checklists included a clear mandate (36.8%) and evidence-based research (26.3%). Checklists are not being universally utilized in the office-based setting. There are barriers preventing their successful implementation. Risk managers may be able to improve patient safety and decrease risk by encouraging practitioners, possibly through incentives, to use customizable safety checklists. © 2014 American Society for Healthcare Risk Management of the American Hospital Association.

    The characterization of light beams has devoted a lot of attention in the past decade. Several formalisms have been presented to treat the problem of parameter invariance and characterization in the propagation of light beam along ideal, ABCD, optical systems. The hard and soft apertured optical systems have been treated too. Also some aberrations have been analyzed, but it has not appeared a formalism able to treat the problem as a whole. In this contribution we use a classical approach to describe the problem of aberrated, and therefore apertured, light beams. The wavefront aberration is included in a pure phase term expanded in terms of the Zernike polynomials. Then, we can use the relation between the lower order Zernike polynomia and the Seidel or third order aberrations. We analyze the astigmatism, the spherical aberration and the coma, and we show how higher order aberrations can be taken into account. We have calculated the divergence, and the radius of curvature of such aberrated beams and the influence of these aberrations in the quality of the light beam. Some numerical simulations have been done to illustrate the method.

    Donor organs are often procured by junior staff in stressful, unfamiliar environments where a single adverse event can be catastrophic. A formalized checklist focused on preprocedural processes related to thoracic donor organ procurement could improve detection and prevention of near miss events. A checklist was developed centered on patient identifiers, organ compatibility and quality, and team readiness. It went through five cycles of feedback and revision using a panel of expert procurement surgeons. Educational in-service sessions were held on the use of the checklist as well as best organ assessment practices. Near miss events before the survey were tallied by retrospective review of 20 procurements, and near misses after checklist implementation were prospectively recorded. We implemented the checklist for 40 donor lung and heart procurements: 20 from Cleveland Clinic and 20 from the University of Minnesota. A final survey assessment was used to determine ease of use. Nine near miss events were reported in 20 procurements before use of the checklist. Thirty-one near miss events of 40 organ procurements were identified and potentially prevented by the checklist. Eighty-seven percent of fellows found the checklist to be unobtrusive to work flow, and 100% believed its use should be mandatory. Mortality was the same before and after implementation of the checklist despite increased patient volumes. Implementation of a simple checklist for use during thoracic organ procurement uncovered a substantial number of near miss events. A preprocedural checklist for all thoracic organ transplants in the United States and abroad is feasible and would likely reduce adverse events. Copyright © 2016 The Society of Thoracic Surgeons.

    To analyze the characteristics, incidence, and appearance of wavefront aberrations in undilated, normal, unoperated eyes. Eighty-eight eyes of 44 healthy male Mexican subjects (mean age 25.32 years, range 18 to 36 yr) were divided into three groups based on uncorrected visual acuity of greater than or equal to 20/20, 20/30, or 20/40. UCVA measurements were obtained using an Acuity Max computer screen chart. Wavefront aberrations were measured with the Nidek OPD-Scan ARK 10000, Ver. 1.11b. All measurements were carried out at the same center by the same technician during a single session, following manufacturer instructions. Background illumination was 3 Lux. Wavefront aberration measurements for each group were statistically analyzed using StatView; an average eye was characterized and the resulting aberrations were simulated using MATLAB. We obtained wavefront aberration maps for the 20/20 undilated normal unoperated eyes for total, low, and high order aberration coefficients. Wavefront maps for right eyes were practically the same as those for left eyes. Higher aberrations did not contribute substantially to total wavefront analysis. Average aberrations of this "normal eye" will be used as criteria to decide the necessity of wavefront-guided ablation in our facilities. We will focus on the nearly zero average of high order aberrations in this normal whole eye as a reference to be matched.

    Longitudinal chromatic aberration (LCA) provides a cue to accommodation with small pupils. However, large pupils increase monochromatic aberrations, which may obscure chromatic blur. In this study, we examined the effect of pupil size and LCA on accommodation. Accommodation was recorded by infrared optometer while observers (nine normal trichromats) viewed a sinusoidally moving Maltese cross target in a Badal stimulus system. There were two illumination conditions: white (3000 K; 20 cd/m) and monochromatic (550 nm with 10 nm bandwidth; 20 cd/m) and two artificial pupil conditions (3 and 5.7 mm). Separately, static measurements of wavefront aberration were made with the eye accommodating to targets between 0 and 4 D (COAS, Wavefront Sciences). Large individual differences in accommodation to wavefront vergence and to LCA are a hallmark of accommodation. LCA continues to provide a signal at large pupil sizes despite higher levels of monochromatic aberrations. Monochromatic aberrations may defend against chromatic blur at high spatial frequencies, but accommodation responds best to optical vergence and to LCA at 3 c/deg where blur from higher order aberrations is less.

The aim of this study was to prospectively audit checklist use in orthopaedic patients before and after implementation of an educational programme designed to increase use and correlate this with early complications, mortality and staff perceptions. Data was collected on 480 patients before the educational program and 485 patients after. Pre-training checklist use was 7.9%. The rates of early complications and mortality were 8.5% and 1.9%, respectively. Forty-seven percent thought the checklist improved team communication. Following an educational program, checklist use significantly increased to 96.9% (RR12.2; 95% CI 9.0-16.6). The rate of early complications and mortality was 7.6% (RR 0.89; 95% CI 0.58-1.37) and 1.6% (RR 0.88; 95% CI 0.34-2.26), respectively. Seventy-seven percent thought the checklist improved team communication. Checklist use was not associated with a significant reduction in early complications and mortality in patients undergoing orthopaedic surgery. Education programs can significantly increase accurate use and staff perceptions following implementation.

    A group of 97 male and 111 female undergraduates completed the Jenkins Activity Survey, the Framingham Type A Scale, the Adjective Checklist Type A Scale, the Spielberger State-Trait Anxiety Inventory, and the Buss-Durkee Hostility Inventory. A factor analysis revealed three dimensions: Anger-Emotionality, Anger-Aggression, and Residual Pattern A. All Type A measures loaded highly on the Type A factor, with the Jenkins Activity Survey loading the highest. The Framingham Type A Scale was related to Anger-Emotionality, the Adjective Checklist Type A Scale was related to Anger-Aggression, and the Jenkins Activity Survey was related to neither of the anger dimensions. Women scored higher than men on Anger-Emotionality and the Guilt, Resentment, and Irritability subscales and lower than men on the Assaultiveness subscale. Women showed higher correlations between Type A and the Guilt subscale, and men between Type A and the Suspiciousness subscale. We conclude that Type A is a multidimensional construct that manifests itself differently in men and women.

    Crisis checklists are cognitive aids used to coordinate care during critical events. Simulation training is a method to validate process improvement initiatives such as checklist implementation. In response to concerns staff members expressed regarding their comfort level when responding to infrequent occurrences such as cardiac arrest and other OR emergencies, the OR Comprehensive Unit-based Safety Program team at our facility decided to institute the use of crisis checklists in the OR during critical events. We provided 90-minute education sessions, simulation opportunities, and debriefings to help staff members become more comfortable using these checklists. Based on program evaluations, 80% of staff members who participated in the training expressed an increased comfort level when caring for a patient in cardiac arrest. Copyright © 2017 AORN, Inc.

    Checklists can be used to improve and standardize safety critical processes and their communication. The introduction of potentially harmful medical technology and equipment has created additional requirements for the safe delivery of health care. We have studied the implementation of an electronic checklist to ensure the safety of patients scheduled for Magnetic Resonance Imaging examinations. Through a combination of observations and semi-structured interviews we investigated how health care workers in a Norwegian University hospital dealt with variations in checklist compliance, missing and lack of information. The checklist provided different functionality for the different users, ranging from a memory/attention support to a standardized form of communication on safety matters. However, the rigidity afforded by the electronic implementation, showed some serious drawbacks over the prior, simpler, paper-based versions.

    Pharmacological effects of bee venom has been reported, however, it has been restricted to the bee venom collected from European honey bee (Apis mellifera). The aim of the present study was to compare the antioxidant activities and irritation properties of venoms collected from four different Apis species in Thailand, which includes Apis cerena (Asian cavity nesting honeybee), Apis florea (dwarf honeybee), Apis dorsata (giant honeybee), and A. mellifera. Melittin content of each bee venom extracts was investigated by using high-performance liquid chromatography. Ferric reducing antioxidant power, 2, 2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid), and 1, 1-diphenyl-2-picrylhydrazyl assay were used to determine the antioxidant activity, whereas, hen's egg test chorioallantoic membrane assay was used to determine the irritation property of each bee venom extracts. Melittin was the major constituent in all bee venom extracts. The melittin content in A. dorsata, A. mellifera, A. florea, and A. cerena were 95.8 ± 3.2%, 76.5 ± 1.9%, 66.3 ± 8.6%, and 56.8 ± 1.8%, respectively. Bee venom extract from A. dorsata possessed the highest antioxidant activity with the inhibition of 41.1 ± 2.2% against DPPH, Trolox equivalent antioxidant capacity of 10.21 ± 0.74 mM Trolox/mg and equivalent concentration (EC 1 ) of 0.35 ± 0.02 mM FeSO 4 /mg. Bee venom extract from A. mellifera exhibited the highest irritation, followed by A. cerena, A. dorsata, and A. florea, respectively. Melittin was the compound responsible for the irritation property of bee venom extracts since it could induce severe irritation (irritation score was 13.7 ± 0.5, at the concentration of 2 mg/ml). The extract from A. dorsata which possessed the highest antioxidant activity showed no irritation up to the concentration of 0.1 mg/ml. Therefore, bee venom extract from A. dorsata at the concentration not more than 0.1 mg/ml would be suggested for using

    A revised checklist of the British and Irish Heloridae and Proctotrupidae (Proctotrupoidea) substantially updates the previous comprehensive checklist, dating from 1978. Country level data (i.e. occurrence in England, Scotland, Wales, Ireland and the Isle of Man) is reported where known. A total of three Heloridae and 39 Proctotrupidae (including only certainly recorded species) represents a 27% increase in the British list since 1978. Most species are still poorly known and there has been a dearth of taxonomic and faunistic work on the British and Irish fauna.

    Although disconnection syndrome has been considered a core pathophysiologic mechanism of schizophrenia, little is known about the temporal behavior of mismatch negativity (MMN) generators in individuals with schizophrenia or clinical high risk (CHR) for psychosis. MMN was assessed in 29 schizophrenia patients, 40 CHR subjects, and 47 healthy controls (HCs). Individual realistic head models and the minimum L2 norm algorithm were used to generate a current source density (CSD) model of MMN. The strength and time course of MMN CSD activity were calculated separately for the frontal and temporal cortices and were compared across brain regions and groups. Schizophrenia patients and CHR subjects displayed lower MMN CSD strength than HCs in both the temporal and frontal cortices. We found a significant time delay in MMN generator activity in the frontal cortex relative to that in the temporal cortex in HCs. However, the sequential temporo-frontal activities of MMN generators were disrupted in both the schizophrenia and CHR groups. Impairments and altered temporal behavior of MMN multiple generators were observed even in individuals at risk for psychosis. These findings suggest that aberrant MMN generator activity might be helpful in revealing the pathophysiology of schizophrenia. Copyright © 2016 International Federation of Clinical Neurophysiology.

    A high proportion of refugees have been subjected to potentially traumatic experiences (PTEs), including torture. PTEs, and torture in particular, are powerful predictors of mental ill health. This paper reports the development and preliminary validation of a brief refugee trauma checklist applicable for survey studies. Methods: A pool of 232 items was generated based on pre-existing instruments. Conceptualization, item selection and item refinement was conducted based on existing literature and in collaboration with experts. Ten cognitive interviews using a Think Aloud Protocol (TAP) were performed in a clinical setting, and field testing of the proposed checklist was performed in a total sample of n = 137 asylum seekers from Syria. Results: The proposed refugee trauma history checklist (RTHC) consists of 2 × 8 items, concerning PTEs that occurred before and during the respondents’ flight, respectively. Results show low item non-response and adequate psychometric properties Conclusions: RTHC is a usable tool for providing self-report data on refugee trauma history surveys of community samples. The core set of included events can be augmented and slight modifications can be applied to RTHC for use also in other refugee populations and settings. PMID:28976937

    In this paper, we develop sixth-order wave aberration theory of ultrawide-angle optical systems like fisheye lenses. Based on the concept and approach to develop wave aberration theory of plane-symmetric optical systems, we first derive the sixth-order intrinsic wave aberrations and the fifth-order ray aberrations; second, we present a method to calculate the pupil aberration of such kind of optical systems to develop the extrinsic aberrations; third, the relation of aperture-ray coordinates between adjacent optical surfaces is fitted with the second-order polynomial to improve the calculation accuracy of the wave aberrations of a fisheye lens with a large acceptance aperture. Finally, the resultant aberration expressions are applied to calculate the aberrations of two design examples of fisheye lenses; the calculation results are compared with the ray-tracing ones with Zemax software to validate the aberration expressions.

  9. Menthol attenuates respiratory irritation and elevates blood cotinine in cigarette smoke exposed mice.

    Addition of menthol to cigarettes may be associated with increased initiation of smoking. The potential mechanisms underlying this association are not known. Menthol, likely due to its effects on cold-sensing peripheral sensory neurons, is known to inhibit the sensation of irritation elicited by respiratory irritants. However, it remains unclear whether menthol modulates cigarette smoke irritancy and nicotine absorption during initial exposures to cigarettes, thereby facilitating smoking initiation. Using plethysmography in a C57Bl/6J mouse model, we examined the effects of L-menthol, the menthol isomer added to cigarettes, on the respiratory sensory irritation response to primary smoke irritants (acrolein and cyclohexanone) and smoke of Kentucky reference 2R4 cigarettes. We also studied L-menthol's effect on blood levels of the nicotine metabolite, cotinine, immediately after exposure to cigarette smoke. L-menthol suppressed the irritation response to acrolein with an apparent IC₅₀ of 4 ppm. Suppression was observed even at acrolein levels well above those necessary to produce a maximal response. Cigarette smoke, at exposure levels of 10 mg/m³ or higher, caused an immediate and marked sensory irritation response in mice. This response was significantly suppressed by L-menthol even at smoke concentrations as high as 300 mg/m³. Counterirritation by L-menthol was abolished by treatment with a selective inhibitor of Transient Receptor Potential Melastatin 8 (TRPM8), the neuronal cold/menthol receptor. Inclusion of menthol in the cigarette smoke resulted in roughly a 1.5-fold increase in plasma cotinine levels over those observed in mice exposed to smoke without added menthol. These findings document that, L-menthol, through TRPM8, is a strong suppressor of respiratory irritation responses, even during highly noxious exposures to cigarette smoke or smoke irritants, and increases blood cotinine. Therefore, L-menthol, as a cigarette additive, may promote smoking

Checklists are part of cycles to improve quality of the care process, promote communication between professionals involved in the different stages, help detect failures and risks, and increase patient safety. The lack of checklists at each stage was identified as a factor contributing to communication failures. To design checklists at different stages of the thyroidectomy care process to improve the communication between the professionals involved. Multidisciplinary working team consisting of specialists in otolaryngology, anesthesiology, and endocrinology. The process of thyroidectomy was divided into three stages (preoperative -A-, operative -B- and postoperative -C-). Potential safety incidents and failures at each stage and their contributing factors (causes) were identified by literature review and brainstorming. Checklists for each checkpoint were designed by consensus of the working group. The items correspond to factors contributing to the occurrence of incidents in the perioperative stage of thyroidectomy related to patients, technological equipment, environment, management, and organization. Lists of items should be checked by the appropriate specialist in each stage. Checklists in thyroid surgery are tools that allow for testing at different checkpoints data related to factors contributing to the occurrence of failures at each stage of the care process.

    Analysis of the prevalence of health effects in large scale databases is key in defining testing strategies within the context of Integrated Approaches on Testing and Assessment (IATA), and is relevant to drive policy changes in existing regulatory toxicology frameworks towards non-animal approaches. A retrospective analysis of existing results from in vivo skin irritation, eye irritation, and skin sensitisation studies on a database of 223 agrochemical formulations is herein published. For skin or eye effects, high prevalence of mild to non-irritant formulations (i.e. per GHS, CLP or EPA classification) would generally suggest a bottom-up approach. Severity of erythema or corneal opacity, for skinor eye effects respectively, were the key drivers for classification, consistent with existing literature. The reciprocal predictivity of skin versus eye irritation and the good negative predictivity of the GHS additivity calculation approach (>85%) provided valuable non-testing evidence for irritation endpoints. For dermal sensitisation, concordance on data from three different methods confirmed the high false negative rate for the Buehler method in this product class. These results have been reviewed together with existing literature on the use of in vitro alternatives for agrochemical formulations, to propose improvements to current regulatory strategies and to identify further research needs.

    The purpose of this study was to advance a checklist of evaluative criteria designed to assess patient-reported outcome (PRO) measures' developmental measurement properties and applicability, which can be used by systematic reviewers, researchers, and clinicians with a varied range of expertise in psychometric measure development methodology. A directed literature search was performed to identify original studies, textbooks, consensus guidelines, and published reports that propose criteria for assessing the quality of PRO measures. Recommendations from these sources were iteratively distilled into a checklist of key attributes. Preliminary items underwent evaluation through 24 cognitive interviews with clinicians and quantitative researchers. Six measurement theory methodological novices independently applied the final checklist to assess six PRO measures encompassing a variety of methods, applications, and clinical constructs. Agreement between novice and expert scores was assessed. The distillation process yielded an 18-item checklist with six domains: (1) conceptual model, (2) content validity, (3) reliability, (4) construct validity, (5) scoring and interpretation, and (6) respondent burden and presentation. With minimal instruction, good agreement in checklist item ratings was achieved between quantitative researchers with expertise in measurement theory and less experienced clinicians (mean kappa 0.70; range 0.66-0.87). We present a simplified checklist that can help guide systematic reviewers, researchers, and clinicians with varied measurement theory expertise to evaluate the strengths and weakness of candidate PRO measures' developmental properties and the appropriateness for specific applications.

    To evaluate whether the average spherical aberration of human astigmatic corneas is statistically equivalent to human nonastigmatic corneas. Spherical aberrations of 445 astigmatic corneas prior to laser vision correction were retrospectively investigated to determine Zernike coefficients for central corneal areas 6 mm in diameter using CTView (Sarver and Associates). Data were divided into groups according to cylinder power (0.01 to 0.25 diopters [D], 0.26 to 0.75 D, 0.76 to 1.06 D, 1.07 to 1.53 D, 1.54 to 2.00 D, and >2.00 D) and according to age by decade. Spherical aberrations were correlated with age and astigmatic power among groups and the entire population. Statistical analyses were conducted, and P<.05 was considered statistically significant. Mean patient age was 42.6±11 years. Astigmatic corneas had an average astigmatic power of 0.78±0.58 D and mean spherical aberration was 0.25±0.13 μm for the entire population and approximately the same (0.27 μm) for individual groups, ranging from 0.23 to 0.29 μm (P>.05 for all tested groups). Mean spherical aberration of astigmatic corneas was not correlated significantly with cylinder power or age (P>.05). Spherical aberrations are similar to those of nonastigmatic corneas, permitting the use of these additional data in the design of aspheric toric intra-ocular lenses.

    2014-01-01

    Background The WHO Surgical Safety Checklist has a growing evidence base to support its role in improving perioperative safety, although its impact is likely to be directly related to the effectiveness of its implementation. There remains a paucity of documented experience from low-resource settings on Checklist implementation approaches. We report an implementation strategy in a public referral hospital in Addis Ababa, Ethiopia, based on consultation, local leadership, formal introduction, and supported supervision with subsequent audit and feedback. Methods Planning, implementation and assessment took place from December 2011 to December 2012. The planning phase, from December 2011 until April 2012, involved a multidisciplinary consultative approach using local leaders, volunteer clinicians, and staff from non-governmental organisations, to draw up a locally agreed and appropriate Checklist. Implementation in April 2012 involved formal teaching and discussion, simulation sessions and role play, with supportive supervision following implementation. Assessment was performed using completed Checklist analysis and staff satisfaction questionnaires at one month and further Checklist analysis combined with semi-structured interviews in December 2012. Results and discussion Checklist compliance rates were 83% for general anaesthetics at one month after implementation, with an overall compliance rate of 65% at eight months. There was a decrease in Checklist compliance over the period of the study to less than 20% by the end of the study period. The ‘Sign out’ section was reported as being the most difficult section of the Checklist to complete, and was missed completely in 21% of cases. The most commonly missed single item was the team introduction at the start of each case. However, we report high staff satisfaction with the Checklist and enthusiasm for its continued use. Conclusion We report a detailed implementation strategy for introducing the WHO Surgical Safety

    The aim of this post-hoc analysis was to evaluate the efficacy of lurasidone in treating major depressive disorder (MDD) with mixed features including irritability. The data in this analysis were derived from a study of patients meeting DSM-IV-TR criteria for unipolar MDD, with a Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≥26, presenting with two or three protocol-defined manic symptoms, and who were randomized to 6 weeks of double-blind treatment with either lurasidone 20-60 mg/d (n=109) or placebo (n=100). We defined "irritability" as a score ≥2 on both the Young Mania Rating Scale (YMRS) irritability item (#5) and the disruptive-aggressive item (#9). Endpoint change in the MADRS and YMRS items 5 and 9 were analyzed using a mixed model for repeated measures for patients with and without irritability. Some 20.7% of patients met the criteria for irritability. Treatment with lurasidone was associated with a significant week 6 change vs. placebo in MADRS score in both patients with (-22.6 vs. -9.5, p<0.0001, effect size [ES]=1.4) and without (-19.9 vs. -13.8, p<0.0001, ES=0.7) irritability. In patients with irritable features, treatment with lurasidone was associated with significant week 6 changes vs. placebo in both the YMRS irritability item (-1.4 vs. -0.3, p=0.0012, ES=1.0) and the YMRS disruptive-aggressive item (-1.0 vs. -0.3, p=0.0002, ES=1.2). In our post-hoc analysis of a randomized, placebo-controlled, 6-week trial, treatment with lurasidone significantly improved depressive symptoms in MDD patients with mixed features including irritability. In addition, irritability symptoms significantly improved in patients treated with lurasidone.

    AIM To evaluate the quality of vision in respect to high order aberrations and straylight perception after implantation of an aspheric, aberration correcting, monofocal intraocular lens (IOL). METHODS Twenty-one patients (34 eyes) aged 50 to 83y underwent cataract surgery with implantation of an aspheric, aberration correcting IOL (Tecnis ZCB00, Abbott Medical Optics). Three months after surgery they were examined for uncorrected (UDVA) and corrected distance visual acuity (CDVA), contrast sensitivity (CS) under photopic and mesopic conditions with and without glare source, ocular high order aberrations (HOA, Zywave II) and retinal straylight (C-Quant). RESULTS Postoperatively, patients achieved a postoperative CDVA of 0.0 logMAR or better in 97.1% of eyes. Mean values of high order abberations were +0.02±0.27 (primary coma components) and -0.04±0.16 (spherical aberration term). Straylight values of the C-Quant were 1.35±0.44 log which is within normal range of age matched phakic patients. The CS measurements under mesopic and photopic conditions in combination with and without glare did not show any statistical significance in the patient group observed (P≥0.28). CONCLUSION The implantation of an aspherical aberration correcting monofocal IOL after cataract surgery resulted in very low residual higher order aberration (HOA) and normal straylight.

    Purpose Longitudinal chromatic aberration (LCA) provides a cue to accommodation with small pupils. However, large pupils increase monochromatic aberrations, which may obscure chromatic blur. In the present study, we examined the effect of pupil size and LCA on accommodation. Methods Accommodation was recorded by infrared optometer while observers (nine normal trichromats) viewed a sinusoidally moving Maltese cross target in a Badal stimulus system. There were two illumination conditions: white (3000 K; 20 cd/m2) and monochromatic (550 nm with 10 nm bandwidth; 20 cd/m2) and two artificial pupil conditions (3 mm and 5.7 mm). Separately, static measurements of wavefront aberration were made with the eye accommodating to targets between 0 and 4 D (COAS, Wavefront Sciences). Results Large individual differences in accommodation to wavefront vergence and to LCA are a hallmark of accommodation. LCA continues to provide a signal at large pupil sizes despite higher levels of monochromatic aberrations. Conclusions Monochromatic aberrations may defend against chromatic blur at high spatial frequencies, but accommodation responds best to optical vergence and to LCA at 3 c/deg where blur from higher order aberrations is less.

    Few studies have investigated the neural systems involved in decreasing behavioral reactivity to emotional stimuli as children age. It has been suggested that this process may interact with temperament-linked variations in neurodevelopment to better explain individual differences in the maturation of emotion regulation. In this investigation, children ages 4 to 12 (n = 30, mean age = 7.62 years, SD = 1.71 years) and adults (n = 21, mean age = 26.67 years) watched clips from popular children's films containing positive, negative, or neutral emotional content during functional magnetic resonance imaging. Compared to adults, children demonstrated greater activation in subcortical and visual regions (hippocampus, thalamus, visual cortex, fusiform) during negative clips and greater activation of subcortical and prefrontal regions during positive clips (hippocampus, thalamus, caudate, ACC, OFC, superior frontal cortex). In children only, we found an age by temperament interaction in frontal and subcortical regions indicating that activation increased as a function of age in the most irritable children, but decreased as a function of age in the least irritable children. Findings were not present in the temperament domain of fear. Findings replicate and extend the existing irritability literature, indicating that healthy children highest in irritability may develop comparatively greater activation of the lateral prefrontal cortex in order to support adaptive regulation during emotional challenges. These results are discussed within the context of the emerging literature on the utility of complex, multidimensional, and naturalistic stimuli, which present a complementary alternative to understanding ecologically valid and sustained neural responses to emotionally evocative stimuli.

    General anaesthesia significantly reduces tear production and normal values are not immediately re-established on ending anaesthesia. Therefore, adequate protection of the cornea has to be assured during the perianaesthetic period. There are various methods available, including taping of the eyelids and the application of eye ointments, gels and drops. In human medicine studies, different formulations were found to induce signs of ocular irritation. The aim of the present study was to determine tear production in cats after general anaesthesia, and to identify possible causes of irritation. Tear production was determined in 41 cats after general anaesthesia and eyes were examined for signs of irritation. Two different anaesthetic protocols were used. To protect the cornea, an ointment and gel were applied to the right and left eyes, respectively. Postoperatively, tear production was significantly reduced for 6 hours and 18 hours in the right and left eyes, respectively. Two hours after anaesthesia, blepharospasm of the right eye was observed in 92.7% (n = 38) of the cats. In contrast, the left eye was always held open. This study demonstrated that tear production in cats is significantly decreased both during and after anaesthesia. The degree of reduction was independent of the anaesthetic protocol. Both the eye ointment and gel proved effective in protecting the corneal surface. However, eye gel use is recommended because the eye ointment consistently caused an irritation comparable to the foreign-body sensation reported in humans.

    Species checklists enlist the species available within the defined geographical region and thus serve as essential input for developing conservation and management strategies. The fields of conservation biology and ecology confront the challenge of inflated biodiversity, attributed to non-recognition of taxonomic inconsistencies such as synonyms, alternate representation, emendations etc. Critical review of the checklists and distributional records of Phylum Echinodermata from Indian waters and subsequent validation of species names with World Register of Marine Species (WoRMS) database, revealed that the current literature included 236 incorrect entries comprising of 162 synonyms, 15 emendations, 5 nomina dubia, 1 nomen nudum, 40 species under alternate representation, 9 species with author misnomer, 1 subspecies and 1 unaccepted. The 226 species found to be mixed with valid names and a revised checklist was prepared. The revised and updated checklist holds 741 species of echinoderms comprising of 182 asteroids (24.56%), 70 crinoids (9.45%), 138 echinoids (18.62%), 179 holothuroids (24.16%) and 172 ophiuroids (23.21%), placed under 28 orders and 107 families. This paper discusses the cause for taxonomic inflation and argues that such taxonomic inconsistencies alter our interpretations of a species including its inaccurate distribution and, could possibly impede the country's conservation and management efforts.

    The Brøset Violence Checklist (BVC) assesses confusion, irritability, boisterousness, verbal threats, physical threats and attacks on objects as either present or absent. It is hypothesised that an individual displaying two or more of these behaviours is more likely to be violent in the next twenty-four hour period. This study aims to test the validity of the instrument in geriatric settings and to report on the predictive value of an easy-to-use risk assessment instrument. Eight thousand eight hundred and thirty-five BVC observations were completed in two psychogeriatric wards (n = 42 patients) and two special care units for patients with dementia (n = 40 residents). To measure violent incidents the study group was monitored using the Staff Observation Aggression Scale-Revised (SOAS-R). This study disclosed that patients in geriatric wards and residents in nursing homes who are aggressive have higher BVC scores than the non-violent subjects indicating that the BVC does predict violent episodes in these settings. From a clinical perspective, it is most important that a prediction aid has good sensitivity, so that most cases are detected and have a high negative predictive value so that most non-cases on the measure are indeed non-cases. Our results indicate that the BVC was able to achieve this goal.

    Recently, the sensory and pulmonary irritating properties of ten metalworking fluids (MWF) were assessed using a mouse bioassay. Relative potency of the MWFs was estimated, but it was not possible to identify the component(s) responsible for the the respiratory irritation induced by each MWF. One of the ten fluids, MWF "ET", produced sensory and pulmonary irritation in mice, and it was of moderate potency in comparison to the other nine MWFs. MWF "E" had three major components: tall oil fatty acids (TOFA), sodium sulfonate (SA), and paraffinic oil (PO). In the present study, the sensory and pulmonary irritating properties of these individual components of MWF "E" were evaluated. Mixtures of the three components were also prepared and similarly evaluated. This analysis revealed that the sensory irritation from MWF "E" was largely due to TOFA, whereas SA produced the pulmonary irritation observed with MWF "E". Both TOFA and SA were more potent irritants than was MWF "E", and the potency of TOFA and/or SA was diminished through combination with PO. There was no evidence of synergism of the components when combined to form MWF "E". This approach for identifying the biologically "active" component(s) in a mixture should be useful for other MWFs. Furthermore, the approach should be easily adapted for other applications involving concerns with mixtures.

    To detect possible differences in residual wavefront aberrations between standard and customized laser refractive surgery based onmathematical modeling, the residual optical aberrations after conventional and customized laser refractive surgery were compared accordingto the ablation profile with transition zone. The results indicated that ablation profile has a significant impact on the residual aberrations.The amount of residual aberrations for conventional correction is higher than that for customized correction. Additionally, the residualaberrations for high myopia eyes are markedly larger than those for moderate myopia eyes. For a 5 mm pupil, the main residual aberrationterm is coma and yet it is spherical aberration for a 7 mm pupil. When the pupil diameter is the same as optical zone or greater, themagnitudes of residual aberrations is obviously larger than that for a smaller pupil. In addition, the magnitudes of the residual fifth orsixth order aberrations are relatively large, especially secondary coma in a 6 mm pupil and secondary spherical aberration in a 7 mm pupil.Therefore, the customized ablation profile may be superior to the conventional correction even though the transition zone and treatmentdecentration are taken into account. However, the customized ablation profile will still induce significant amount of residual aberrations.

    Recent behavioral and neuroimaging studies have suggested multisensory processing deficits in patients with schizophrenia (SCZ). Thus far, the neural mechanisms underlying these deficits are not well understood. Previous studies with unisensory stimulation have shown altered neural oscillations in SCZ. As such, altered oscillations could contribute to aberrant multisensory processing in this patient group. To test this assumption, we conducted an electroencephalography (EEG) study in 15 SCZ and 15 control participants in whom we examined neural oscillations and event-related potentials (ERPs) in the sound-induced flash illusion (SIFI). In the SIFI multiple auditory stimuli that are presented alongside a single visual stimulus can induce the illusory percept of multiple visual stimuli. In SCZ and control participants we compared ERPs and neural oscillations between trials that induced an illusion and trials that did not induce an illusion. On the behavioral level, SCZ (55.7%) and control participants (55.4%) did not significantly differ in illusion rates. The analysis of ERPs revealed diminished amplitudes and altered multisensory processing in SCZ compared to controls around 135 ms after stimulus onset. Moreover, the analysis of neural oscillations revealed altered 25–35 Hz power after 100 to 150 ms over occipital scalp for SCZ compared to controls. Our findings extend previous observations of aberrant neural oscillations in unisensory perception paradigms. They suggest that altered ERPs and altered occipital beta/gamma band power reflect aberrant multisensory processing in SCZ. PMID:27999553

    III Rome Criteria of functional gastrointestinal disorders in children, distinguished the disturbances with abdominal pain, to which irritable bowel syndrome, functional abdominal pains, functional dyspepsia and abdominal migraine were included. THE AIM OF THE STUDY was sonographic assessment of the gallbladder and its contractility in functional abdominal pain and irritable bowel syndrome in children. The study comprised 96 children aged 6 to 18 years, 59 girls and 37 boys. Depending on diagnosis, the children were divided into three groups. 38 children with functional abdominal pain constituted the first group, 26 children with irritable bowel syndrome were included to the second group, the third group consisted of 32 healthy children (control group). Diagnosis of functional abdominal pain and irritable bowel syndrome was made based on the III Rome Criteria. In irritable bowel syndrome both forms with diarrhea (13) and with constipation (13) were observed. Anatomy and contractility of the gallbladder were assessed by ultrasound examination. The presence of septum, wall thickness, thick bile, vesicle volume in fasting state and 30th and 60th minute after test meal were taken into consideration. Test meal comprised about 15% of caloric requirement of moderate metabolism. Children with bile stones and organic diseases were excluded from the study. Thickened vesicle wall and thick bile were present more frequently in children with irritable bowel syndrome and functional abdominal pain than in control group (p < 0.02). Fasting vesicle volume was significantly greater in children with functional abdominal pain than in irritable bowel syndrome and control group (p = 0.003, p = 0.05). Vesicle contractility after test meal was greatest in children with functional abdominal pain. Evaluation of diminished (smaller than 30%) and enlarged (greater then 80%) gallbladder contractility at 30th and 60th minute after test meal demonstrated disturbances of contractility in children

    The human eye aberrations are important for visual acuity and ophthalmic diagnostics and surgical procedures. Reported monochromatic aberration data of the normal 20/20 human eyes are scarce. There exist even fewer reports of the relation between ametropic conditions and aberrations. We theoretically investigate the monochromatic and chromatic aberrations of human eyes for refractive errors of -10 to +10 diopters. Schematic human eye models are employed using optical design software for axial, index, and refractive types of ametropia.

    To determine the corneal surfaces and lens contributions to ocular aberrations. There were 61 healthy participants with ages ranging from 20 to 55 years and refractions -8.25 diopters (D) to +3.25 D. Anterior and posterior corneal topographies were obtained with an Oculus Pentacam, and ocular aberrations were obtained with an iTrace aberrometer. Raytracing through models of corneas provided total corneal and surface component aberrations for 5-mm-diameter pupils. Lenticular contributions were given as differences between ocular and corneal aberrations. Theoretical raytracing investigated influence of object distance on aberrations. Apart from defocus, the highest aberration coefficients were horizontal astigmatism, horizontal coma, and spherical aberration. Most correlations between lenticular and ocular parameters were positive and significant, with compensation of total corneal aberrations by lenticular aberrations for 5/12 coefficients. Anterior corneal aberrations were approximately three times higher than posterior corneal aberrations and usually had opposite signs. Corneal topographic centers were displaced from aberrometer pupil centers by 0.32 ± 0.19 mm nasally and 0.02 ± 0.16 mm inferiorly; disregarding corneal decentration relative to pupil center was significant for oblique astigmatism, horizontal coma, and horizontal trefoil. An object at infinity, rather than at the image in the anterior cornea, gave incorrect aberration estimates of the posterior cornea. Corneal and lenticular aberration magnitudes are similar, and aberrations of the anterior corneal surface are approximately three times those of the posterior surface. Corneal decentration relative to pupil center has significant effects on oblique astigmatism, horizontal coma, and horizontal trefoil. When estimating component aberrations, it is important to use correct object/image conjugates and heights at surfaces.

    A new technology of deformable mirror will be presented. Based on magnetic actuators, these deformable mirrors feature record strokes (more than +/- 45μm of astigmatism and focus correction) with an optimized temporal behavior. Furthermore, the development has been made in order to have a large density of actuators within a small clear aperture (typically 52 actuators within a diameter of 9.0mm). We will present the key benefits of this technology for vision science: simultaneous correction of low and high order aberrations, AO-SLO image without artifacts due to the membrane vibration, optimized control, etc. Using recent papers published by Doble, Thibos and Miller, we show the performances that can be achieved by various configurations using statistical approach. The typical distribution of wavefront aberrations (both the low order aberration (LOA) and high order aberration (HOA)) have been computed and the correction applied by the mirror. We compare two configurations of deformable mirrors (52 and 97 actuators) and highlight the influence of the number of actuators on the fitting error, the photon noise error and the effective bandwidth of correction.

    While checklists are often used to score standardized patient based clinical assessments, little research has focused on issues related to their development or the level of agreement with respect to the importance of specific items. Five physicians independently reviewed checklists from 11 simulation scenarios that were part of the former Educational Commission for Foreign Medical Graduate's Clinical Skills Assessment and classified the clinical appropriateness of each of the checklist items. Approximately 78% of the original checklist items were judged to be needed, or indicated, given the presenting complaint and the purpose of the assessment. Rater agreement was relatively poor with pairwise associations (Kappa coefficient) ranging from 0.09 to 0.29. However, when only consensus indicated items were included, there was little change in examinee scores, including their reliability over encounters. Although most checklist items in this sample were judged to be appropriate, some could potentially be eliminated, thereby minimizing the scoring burden placed on the standardized patients. Periodic review of checklist items, concentrating on their clinical importance, is warranted.

    Attention-deficit/hyperactivity disorder (ADHD) affects functioning of the family, decreasing interactions and loyalty and increasing conflict between adolescents with ADHD and their families. Irritable mood and difficulties with emotional dysregulation are common in children with ADHD. The objective of the current study was to assess levels of irritability in adolescents with ADHD using self- and parent-report scales, and investigate the relationship between irritability levels and parental attitudes. A total of 47 adolescents with ADHD and 39 adolescents with typical development participated in the current study. Findings demonstrated that higher levels of parent-reported irritability were associated with decreased egalitarian attitudes in the ADHD group. Although other parental attitudes were not associated with self- and parent-reported irritability, evaluation of the relationship between parental attitudes and irritability in adolescents with ADHD, which can guide diagnosis and treatment of ADHD, is of critical importance.

    Irritability is a common feature of many psychiatric disorders, including both externalizing and internalizing disorders. There is little research, however, examining associations between irritability and these symptom domains, particularly during the important developmental period of adolescence, characterized by sex differences in the prevalence of disorders. We examined the cross-sectional associations between irritability, measured with the Affective Reactivity Index, and symptoms of externalizing and internalizing domains of psychopathology, measured with the Youth Self Report, in a volunteer community sample (N = 183) of 9- to 13-year-old (M = 11.39, SD = 1.07) boys and girls (37% White/Caucasian, 8% Asian, 11% Hispanic, 8% African American, 2% Native American, 2% Pacific Islander, 28% Other, and 3% not reported). A subset of the sample (n = 112) provided data at a 2-year follow-up, used to extend these associations. There were no sex differences in levels of irritability; however, the associations between irritability and symptom domains were moderated by sex. Specifically, in girls, irritability was associated equally with externalizing and internalizing symptoms. In contrast, in boys, irritability was associated more strongly with externalizing symptoms than with internalizing symptoms. Thus, across both sexes, irritability was moderately associated with externalizing symptoms, but the association between irritability and internalizing symptoms was stronger in girls than in boys. At follow-up, sex moderated the association between baseline irritability and later externalizing and internalizing symptoms. These findings indicate that irritability is associated with both externalizing and internalizing symptoms in early adolescence and that irritability is associated with internalizing symptoms more strongly in girls than in boys.

    Cross-sectional, longitudinal, and genetic associations exist between irritability and depression. Prior studies have examined developmental trajectories of irritability, clinical outcomes, and associations with child and familial depression. However, studies have not integrated neurobiological measures. The present study examined developmental trajectories of irritability, clinical outcomes, and cortical structure among preschoolers oversampled for depressive symptoms. Beginning at 3 to 5 years old, a sample of 271 children enriched for early depressive symptoms were assessed longitudinally by clinical interview. Latent class mixture models identified trajectories of irritability severity. Risk factors, clinical outcomes, and cortical thickness were compared across trajectory classes. Cortical thickness measures were extracted from 3 waves of magnetic resonance imaging at 7 to 12 years of age. Three trajectory classes were identified among these youth: 53.50% of children exhibited elevated irritability during preschool that decreased longitudinally, 30.26% exhibited consistently low irritability, and 16.24% exhibited consistently elevated irritability. Compared with other classes, the elevated irritability class exhibited higher rates of maternal depression, early life adversity, later psychiatric diagnoses, and functional impairment. Further, elevated baseline irritability predicted later depression beyond adversity and personal and maternal depression history. The elevated irritability class exhibited a thicker cortex in the left superior frontal and temporal gyri and the right inferior parietal lobule. Irritability manifested with specific developmental trajectories in this sample enriched for early depression. Persistently elevated irritability predicted poor psychiatric outcomes, higher risk for later depression, and decreased overall function later in development. Greater frontal, temporal, and parietal cortical thickness also was found, providing neural

    Airway irritation is a major drawback of desflurane anesthesia. This study was designed to evaluate the effect of intravenous fentanyl given before thiopental induction on airway irritation caused by a stepwise increase in desflurane in children. Eighty children (2-8 years) were enrolled in a randomized, double-blind study. Forty received saline and 40 received 2 microg/kg of fentanyl intravenously; this was followed by thiopental sodium 5 mg/kg in both groups. Patients were assistant-ventilated with desflurane 1%, which was then increased by 1% every six breaths up to 10%. During this period, cough, secretion, excitation and apnea were graded and the desflurane concentration at which airway irritation symptoms first occurred was recorded. The results were analyzed using Pearson's chi-squared test. The incidence of typical airway irritation events was lower with fentanyl than with saline (cough, 2.5% vs. 42.5%; secretion, 27.5% vs. 82.5%; excitation, 10% vs. 82.5%; apnea, 20% vs. 65%; P < 0.05). The mean expired desflurane concentration at which the first airway irritation symptom occurred was greater with fentanyl than with saline (7.3% vs. 5.5%, P < 0.05). Intravenous fentanyl in children reduces airway complications caused by desflurane.

    In an effort to explore the use of alternative methods to animal testing for the evaluation of the ocular irritancy of medical devices, we evaluated representative contact lenses with the bovine corneal opacity and permeability test (BCOP) and an in vitro eye irritation test using the three-dimensionally-reconstructed human corneal epithelium (RhCE) models, EpiOcular™ and MCTT HCE™. In addition, we compared the obtained results with the ISO standard in vivo rabbit eye irritation test (ISO10993-10). Along with the positive controls (benzalkonium chloride, BAK, 0.02, 0.2, and 1%), the extracts of 4 representative contact lenses (soft, disposable, hard, and colored lenses) and 2 reference lenses (dye-eluting and BAK-coated lenses) were tested. All the lenses, except for the BAK-coated lens, were determined non-irritants in all test methods, while the positive controls yielded relevant results. More importantly, BCOP, EpiOcular™, and MCTT HCE™ yielded a consistent decision for all the tested samples, with the exception of 0.2% BAK in BCOP, for which no prediction could be made. Overall, all the in vitro tests correlated well with the in vivo rabbit eye irritation test, and furthermore, the combination of in vitro tests as a tiered testing strategy was able to produce results similar to those seen in vivo. These observations suggest that such methods can be used as alternative assays to replace the conventional in vivo test method in the evaluation of the ocular irritancy of ophthalmic medical devices, although further study is necessary.

  9. Aberration correction for charged particle lithography

    NASA Astrophysics Data System (ADS)

    Munro, Eric; Zhu, Xieqing; Rouse, John A.; Liu, Haoning

    2001-12-01

    At present, the throughput of projection-type charge particle lithography systems, such as PREVAIL and SCALPEL, is limited primarily by the combined effects of field curvature in the projection lenses and Coulomb interaction in the particle beam. These are fundamental physical limitations, inherent in charged particle optics, so there seems little scope for significantly improving the design of such systems, using conventional rotationally symmetric electron lenses. This paper explores the possibility of overcoming the field aberrations of round electron lense, by using a novel aberration corrector, proposed by Professor H. Rose of University of Darmstadt, called a hexapole planator. In this scheme, a set of round lenses is first used to simultaneously correct distortion and coma. The hexapole planator is then used to correct the field curvature and astigmatism, and to create a negative spherical aberration. The size of the transfer lenses around the planator can then be adjusted to zero the residual spherical aberration. In a way, an electron optical projection system is obtained that is free of all primary geometrical aberrations. In this paper, the feasibility of this concept has been studied with a computer simulation. The simulations verify that this scheme can indeed work, for both electrostatic and magnetic projection systems. Two design studies have been carried out. The first is for an electrostatic system that could be used for ion beam lithography, and the second is for a magnetic projection system for electron beam lithography. In both cases, designs have been achieved in which all primary third-order geometrical aberrations are totally eliminated.

  14. The identification and classification of skin irritation hazard by a human patch test.

    1994-08-01

    There exist various regulatory instruments the purpose of which is to ensure that the intrinsic toxic hazards associated with substances and preparations are identified. In the context of identification of skin irritation potential, the method is normally the Draize test. Guidance notes provided by the OECD and the EEC expect that corrosive substances will have been screened out by a variety of methods. Substances or preparations which cause a sufficient degree of skin irritation will be classified as skin irritants. The primary motivation behind the present work was to introduce the concept that it is possible to assess the hazard potential of a substance or preparation to produce skin irritation in a human study. In the example presented here, 20% sodium lauryl sulfate (SLS) has been chosen as the positive control. With the protocol currently devised, occluded patch treatment with 20% SLS for up to 4 hr produces an irritant response in just over half of the panel. An irritant response is taken as a clinically evident and significant increase in erythema, oedema or dryness--a minimum of a+ reaction on the ICDRG scale. At such a level of response with the positive control (both in terms of intensity and in proportion of the panel), it is then possible to judge and/or to determine statistically, whether the test material has produced a level of skin irritation which is similar to, greater, or lower than the positive control. In this way a human patch test protocol can form a fundamental component of a strategy for the replacement of animals in determination of skin irritation and corrosion potential. By use of a careful and progressive protocol and by comparison of test data against a positive control it is both possible and practical to classify substances and preparations in terms of their skin irritation potential using that endpoint in the species of concern, man.

    Surgical safety checklists reduce perioperative complications and mortality. Given that minimally invasive surgery (MIS) is dependent on technology and vulnerable to equipment failure, SAGES and AORN partnered to create a MIS checklist to optimize case flow and minimize errors. The aim of this project was to evaluate the effectiveness of the SAGES/AORN checklist in preventing disruptions and determine its ease of use. The checklist was implemented across four institutions and completed by the operating team. To assess its effectiveness, we recorded how often the checklist identified problems and how frequently each of the 45 checklist items were not completed. The perceived usefulness, ease of use, and frustration associated with checklist use were rated on a 5-point Likert scale by the surgeon. We assessed any differences dependent on timing of checklist completion and among institutions. The checklist was performed during MIS procedures (n = 114). When used before the procedure (n = 36), the checklist identified missing items in 13 cases (36.11 %). When used after the procedure (n = 61), the checklist identified missing items in 18 cases (29.51 %) that caused a delay of 4.1 ± 11.1 min. The most frequently missed items included preference card review (14.0 %), readiness of the carbon dioxide insufflator (8.7 %), and availability of the Veress needle (3.6 %). The checklist took an average of 3.6 ± 2.7 min to complete with its usefulness rated 2.6 ± 1.5, ease of use 2.0 ± 1.2, and frustration 1.3 ± 1.1. The checklist identified problems in 24 % of cases that led to preventable delays. The checklist was easy to complete and not frustrating, indicating it could improve operative flow. This study also identified the most useful items which may help abbreviate the checklist, minimizing the frustration and time taken to complete it while maximizing its utility. These attributes of the SAGES/AORN MIS checklist should be explored in future

    Background/Aims Behavioral and psychological symptoms of dementia (BPSDs) negatively impact the prognosis of dementia patients and increase caregiver distress. The aims of this study were to clarify the differences of trajectories of 12 kinds of BPSDs by disease severity in four major dementias and to develop charts showing the frequency, severity, and associated caregiver distress (ACD) of BPSDs using the data of a Japan multicenter study (J-BIRD). Methods We gathered Neuropsychiatric Inventory (NPI) data of patients with Alzheimer’s disease (AD; n = 1091), dementia with Lewy bodies (DLB; n = 249), vascular dementia (VaD; n = 156), and frontotemporal lobar degeneration (FTLD; n = 102) collected during a 5-year period up to July 31, 2013 in seven centers for dementia in Japan. The NPI composite scores (frequency × severity) of 12 kinds of items were analyzed using a principal component analysis (PCA) in each dementia. The factor scores of the PCA were compared in each dementia by disease severity, which was determined with Clinical Dementia Rating (CDR). Results Significant increases with higher CDR scores were observed in 1) two of the three factor scores which were loaded for all items except euphoria in AD, 2) two of the four factor scores for apathy, aberrant motor behavior (AMB), sleep disturbances, agitation, irritability, disinhibition, and euphoria in DLB, and 3) one of the four factor scores for apathy, depression, anxiety, and sleep disturbances in VaD. However, no increases were observed in any of the five factor scores in FTLD. Conclusions As dementia progresses, several BPSDs become more severe, including 1) apathy and sleep disturbances in AD, DLB, and VaD, 2) all of the BPSDs except euphoria in AD, 3) AMB, agitation, irritability, disinhibition, and euphoria in DLB, and 4) depression and anxiety in VaD. Trajectories of BPSDs in FTLD were unclear. PMID:27536962

    The vaginal mucosa is commonly exposed to chemicals and therapeutic agents that may result in irritation and/or inflammation. In addition to acute effects, vaginal irritation and inflammation can make women more susceptible to infections such as HIV-1 and herpes simplex virus 2 (HSV-2). Hence, the vaginal irritation potential of feminine care formulations and vaginally administered therapeutic agents is a significant public health concern. Traditionally, testing of such materials has been performed using the rabbit vaginal irritation (RVI) assay. In the current study, we investigated whether the organotypic, highly differentiated EpiVaginal™ tissue could be used as a non-animal alternative to the RVI test. The EpiVaginal tissue was exposed to a single application of ingredients commonly found in feminine hygiene products and the effects on tissue viability (MTT assay), barrier disruption (measured by transepithelial electrical resistance, TEER and sodium fluorescein (NaFl) leakage), and inflammatory cytokine release (interleukin (IL)-1α, IL-1β, IL-6, and IL-8) patterns were examined. When compared to untreated controls, two irritating ingredients, nonoxynol 9 and benzalkonium chloride, reduced tissue viability to <40% and TEER to <60% while increasing NaFl leakage by 11-24% and IL-1α and IL-1β release by >100%. Four other non-irritating materials had minimal effects on these parameters. Assay reproducibility was confirmed by testing the chemicals using three different tissue production lots and by using tissues reconstructed from cells obtained from three different donors. Coefficients of variation between tissue lots reconstructed with cells obtained from the same donor or lots reconstructed with cells obtained from different donors were less than 10% and 12%, respectively. In conclusion, decreases in tissue viability and barrier function and increases in IL-1α and IL-1β release appear to be useful endpoints for preclinical screening of topically applied

    Loss-of-function mutations in the filaggrin gene (FLG) are associated with xerosis, atopic dermatitis, and early onset of hand eczema. Irritant exposure is a risk factor for occupational hand eczema, and FLG mutations increase the risk of occupational irritant contact dermatitis on the hands in hospital cohorts. It is unknown whether FLG mutations affect the level of irritant exposure. To evaluate whether exposure to occupational irritants was dependent on FLG mutations, atopic dermatitis, and age at hand eczema onset. Randomly chosen Danish adults completed a questionnaire on general health and occupational exposures. Genotyping for FLG mutations (R501X, 2282del4, and R2447X) and patch testing were performed. Overall, 38.7% of subjects reported present or previous occupational exposure to irritants. Among individuals who reported hand eczema onset before entering their work life, 50.6% (45/89) of FLG non-mutation carriers became exposed to irritants, as compared with 28.6% (4/14) of heterozygous and 0% (0/6) of homozygous mutation carriers (p = 0.006). Avoidance was conspicuous among mutation carriers reporting childhood hand eczema and atopic dermatitis (odds ratio 0.08, 95% confidence interval 0.01-0.65). Carriers of FLG mutations who have had hand eczema onset in childhood avoid occupational exposure to irritants; the association is most marked with homozygous mutation status combined with atopic dermatitis. © 2013 John Wiley & Sons A/S.

    Patients with irritative voiding dysfunction are often unresponsive to standard clinical treatment. We evaluated the response of such individuals to transcutaneous electrical stimulation of the third sacral nerve. 32 patients with refractory irritative voiding dysfunction (31 female and 1 male; mean age 47 years) were recruited to the study. Ambulatory transcutaneous electrical neurostimulation was applied bilaterally to the third sacral dermatomes for 1 week. Symptoms of frequency, nocturia, urgency, and bladder pain were scored by each patient throughout and up to 6 months following treatment. The mean daytime frequency was reduced from 11.3 to 7.96 (p = 0.01). Nocturia episodes were reduced from a mean of 2.6 to 1.8 (p = 0.01). Urgency and bladder pain mean symptom scores were reduced from 5.97 to 4.89 and from 1.48 to 0.64, respectively. After stopping therapy, symptoms returned to pretreatment levels within 2 weeks in 40% of the patients and within 6 months in 100%. Three patients who continued with neurostimulation remained satisfied with this treatment modality at 6 months. Transcutaneous third sacral nerve stimulation may be an effective and noninvasive ambulatory technique for the treatment of patients with refractory irritative voiding dysfunction. Following an initial response, patients may successfully apply this treatment themselves to ensure long-term relief.

    Functional abdominal pain disorders, including irritable bowel syndrome, are common in children and treatment can often be difficult. Pharmacological therapies and complementary treatments are widely used, despite the limited data in pediatrics. Areas covered: This review provides an overview of the available data for the use of diet, probiotics, percutaneous electrical nerve stimulation, and psychosocial interventions, including hypnotherapy, yoga, cognitive and behavioral therapy, and mind-body interventions for the treatment of functional abdominal pain disorders in children. The literature review included a PubMed search by each therapy, children, abdominal pain, and irritable bowel syndrome. Relevant articles to this review are discussed. Expert commentary: The decision on the use of pharmacological and complementary therapies should be based on clinical findings, evidence, availability, and in-depth discussion with the patient and family. The physician should provide education on the different interventions and their role on the treatment in an empathetic and warm manner providing ample time for the family to ask questions.

    Abstract: Pediatric Bipolar Disorder (BD) is a highly morbid pediatric psychiatric disease, consistently associated with family psychiatric history of mood disorders and associated with high levels of morbidity and disability and with a great risk of suicide. While there is a general consensus on the symptomatology of depression in childhood, the phenomenology of pediatric mania is still highly debated and the course and long-term outcome of pediatric BD still need to be clarified. We reviewed the available studies on the phenomenology of pediatric mania with the aim of summarizing the prevalence, demographics, clinical correlates and course of these two types of pediatric mania. Eighteen studies reported the number of subjects presenting with either irritable or elated mood during mania. Irritability has been reported to be the most frequent clinical feature of pediatric mania reaching a sensitivity of 95–100% in several samples. Only half the studies reviewed reported on number of episodes or cycling patterns and the described course was mostly chronic and ultra-rapid whereas the classical episodic presentation was less common. Few long-term outcome studies have reported a diagnostic stability of mania from childhood to young adult age. Future research should focus on the heterogeneity of irritability aiming at differentiating distinct subtypes of pediatric psychiatric disorders with distinct phenomenology, course, outcome and biomarkers. Longitudinal studies of samples attending to mood presentation, irritable versus elated, and course, chronic versus episodic, may help clarify whether these are meaningful distinctions in the course, treatment and outcome of pediatric onset bipolar disorder.

    2016-01-01

    Background: In health care, most preventable adverse events occur in the operating room. Surgical safety checklists have become a standard of care for safe operating room practice, but there is conflicting evidence for the effectiveness of checklists to improve perioperative outcomes in some populations. Our objective was to determine whether surgical safety checklists are associated with a reduction in the proportion of children who had perioperative complications. Methods: We conducted a retrospective cohort study using administrative health care databases housed at the Institute for Clinical Evaluative Sciences to compare the risk of perioperative complications in children undergoing common types of surgery before and after the mandated implementation of surgical safety checklists in 116 acute care hospitals in Ontario. The primary outcome was a composite outcome of 30-day all-cause mortality and perioperative complications. Results: We identified 14 458 and 14 314 surgical procedures in pre- and postchecklist groups, respectively. The proportion of children who had perioperative complications was 4.08% (95% confidence interval [CI] 3.76%–4.40%) before the implementation of the checklist and 4.12% (95% CI 3.80%–4.45%) after implementation. After we adjusted for confounding factors, we found no significant difference in the odds of perioperative complications after the introduction of surgical safety checklists (adjusted odds ratio 1.01, 95% CI 0.90–1.14, p = 0.9). Interpretation: The implementation of surgical safety checklists for pediatric surgery in Ontario was not associated with a reduction in the proportion of children who had perioperative complications.

    The incidence of sudden death appears to be 20 times higher in patients with epilepsy compared with the general population. Epilepsy-related death, particularly sudden unexpected death in epilepsy (SUDEP), is still underestimated by healthcare professionals and this may reflect the mistaken belief that epilepsy is a benign condition. The risk of death associated with epilepsy appeared rarely to have been discussed with patients or their families. It appears the decision to discuss SUDEP and also to peg SUDEP risk is arbitrary and clinical. Unfortunately there is no structured evidenced mechanism at present to represent person centered risk of SUDEP and there is currently no easy manner or template to have this discussion with the family and the patient. We conducted a detailed literature review in Medline, Embase and Psychinfo databases to extract the common risk factors as evidenced from literature till date. Research into risk factors has identified a number of risk factors for SUDEP, some of which are potentially modifiable. Based on the literature review, we believe that the ascertained risk factors could be employed in clinical practice as a checklist to reduce an individual patient's risk of SUDEP. The SUDEP safety checklist may be of practical use in reducing risks in some individuals and is definitely of use in helping communication. An evidence based checklist identifying the major risk factors can help both clinicians and patients to focus on minimizing certain risk factors and promote safety by focusing on the modifiable factors and guide treatment. It can be a tool to open a person centered discussion with patients and to outline how individual behaviors could impact on risk. Copyright © 2013 British Epilepsy Association.

    Although ortho-phthalaldehyde (OPA) has been suggested as an alternative to glutaraldehyde for the sterilization and disinfection of hospital equipment, the toxicity has not been thoroughly investigated. The purpose of these studies was to evaluate the irritancy and sensitization potential of OPA. The EpiDerm Skin Irritation Test was used to evaluate in vitro irritancy potential of OPA and glutaraldehyde. Treatment with 0.4125 and 0.55% OPA induced irritation, while glutaraldehyde exposure at these concentrations did not. Consistent with the in vitro results, OPA induced irritancy, evaluated by ear swelling, when mice were treated with 0.75%. Initial evaluation of the sensitization potential was conducted using the local lymph node assay at concentrations ranging from 0.005 to 0.75%. A concentration-dependent increase in lymphocyte proliferation was observed with a calculated EC3 value of 0.051% compared to that of 0.089%, previously determined for glutaraldehyde. Immunoglobulin (Ig) E-inducing potential was evaluated by phenotypic analysis of draining lymph node (DLN) cells and measurement of total and specific serum IgE levels. The 0.1 and 0.75% exposed groups yielded significant increases in the IgE+B220+ cell population in the lymph nodes while the 0.75% treated group demonstrated significant increases in total IgE, OPA-specific IgE, and OPA-specific IgG1. In addition, significant increases in interleukin-4 messenger RNA and protein expression in the DLNs were observed in OPA-treated groups. The results demonstrate the dermal irritancy and allergic potential of OPA and raise concern about the proposed/intended use of OPA as a safe alternative to glutaraldehyde. PMID:20176622

    Transition from film-screen to digital radiography requires changes in radiographic technique and workflow processes to ensure that the minimum radiation exposure is used while maintaining diagnostic image quality. Checklists have been demonstrated to be useful tools for decreasing errors and improving safety in several areas, including commercial aviation and surgical procedures. The Image Gently campaign, through a competitive grant from the FDA, developed a checklist for technologists to use during the performance of digital radiography in pediatric patients. The checklist outlines the critical steps in digital radiography workflow, with an emphasis on steps that affect radiation exposure and image quality. The checklist and its accompanying implementation manual and practice quality improvement project are open source and downloadable at www.imagegently.org. The authors describe the process of developing and testing the checklist and offer suggestions for using the checklist to minimize radiation exposure to children during radiography.

    This is the first study to investigate whether positive family history (FH) of psychosis and affective disorders moderates the relationship between child diagnostic status and parent-reported social and behavioral problems on the Child Behavior Checklist (CBCL) in clinical high-risk adolescents. This longitudinal investigation assessed 122 participants (mean age=14.25±1.8years) from three groups (at-risk, other personality disorders, non-psychiatric controls) at baseline and one year follow-up. As predicted, there was a main effect of FH for a number of CBCL scales indicating higher scores for adolescents with positive FH. The findings also demonstrate a significant Diagnostic Status×Family History interaction for several behavioral scales providing support for FH as a concurrent and longitudinal moderator of the relationship between diagnostic status and CBCL scales. The moderating effect is present for areas of functioning associated with depression, anxiety, social adjustment, thought problems, attention problems, and aggressive behavior. The findings also indicate that both positive and negative symptoms are related to the genetic vulnerability for developing psychosis in clinical high-risk individuals, particularly those symptoms reflective of emotional, attentional, and interpersonal functioning. The present findings are novel and have significant clinical and research implications. This investigation provides a platform for future studies to clarify further the role of FH in clinical high-risk individuals and contributes to integration of this knowledge in the development of early intervention and prevention approaches in at-risk populations for the emergence of severe mental illness.

    When benzalkonium chloride (BKC), a cationic surfactant, is added to sodium dodecyl sulfate (SDS), an anionic surfactant, and used in patch testing, on the basis of their known physicochemical interaction, it is possible to predict that there will be a tendency towards a reduction in the expected irritant response when compared to SDS alone. The aim of this study was to investigate whether BKC could reduce the irritant response to SDS when applied after the SDS exposure. 54 non-atopic adult volunteers were recruited for the study. 20% SDS was applied for 2 h under occlusion. 1% BKC was then applied to the same site. Various controls, including SDS application followed by water for 2 h, were included. The irritant reaction was assessed at 24 h and 48 h. 40 of the 54 subjects had some reaction when SDS was applied for 2 h followed by either benzalkonium chloride or water control under occlusion. In comparison to water control, where BKC was applied after SDS, 20 of the 40 responders had a weaker reaction but only 4 had a stronger response. This study shows that BKC applied to skin exposed to SDS attenuates the resulting irritant reaction.

    To determine if human accommodation uses the eye's own monochromatic aberrations to track dynamic accommodative stimuli. Wavefront aberrations were measured while subjects monocularly viewed a monochromatic Maltese cross moving sinusoidally around 2D of accommodative demand with 1D amplitude at 0.2 Hz. The amplitude and phase (delay) of the accommodation response were compared to the actual vergence of the stimulus to obtain gain and temporal phase, calculated from wavefront aberrations recorded over time during experimental trials. The tested conditions were as follows: Correction of all the subject's aberrations except defocus (C); Correction of all the subject's aberrations except defocus and habitual second-order astigmatism (AS); Correction of all the subject's aberrations except defocus and odd higher-order aberrations (HOAs); Correction of all the subject's aberrations except defocus and even HOAs (E); Natural aberrations of the subject's eye, i.e., the adaptive-optics system only corrected the optical system's aberrations (N); Correction of all the subject's aberrations except defocus and fourth-order spherical aberration (SA). The correction was performed at 20 Hz and each condition was repeated six times in randomised order. Average gain (±2 standard errors of the mean) varied little across conditions; between 0.55 ± 0.06 (SA), and 0.62 ± 0.06 (AS). Average phase (±2 standard errors of the mean) also varied little; between 0.41 ± 0.02 s (E), and 0.47 ± 0.02 s (O). After Bonferroni correction, no statistically significant differences in gain or phase were found in the presence of specific monochromatic aberrations or in their absence. These results show that the eye's monochromatic aberrations are not necessary for accommodation to track dynamic accommodative stimuli. © 2017 The Authors.

    Self-report checklists are used to assess computer workstation set up, typically by workers not trained in ergonomic assessment or checklist interpretation.Though many checklists exist, few have been evaluated for reliability and validity. This study examined reliability and validity of the Computer Workstation Checklist (CWC) to identify mismatches between workers' self-reported workstation problems. The CWC was completed at baseline and at 1 month to establish reliability. Validity was determined with CWC baseline data compared to an onsite workstation evaluation conducted by an expert in computer workstation assessment. Reliability ranged from fair to near perfect (prevalence-adjusted bias-adjusted kappa, 0.38-0.93); items with the strongest agreement were related to the input device, monitor, computer table, and document holder. The CWC had greater specificity (11 of 16 items) than sensitivity (3 of 16 items). The positive predictive value was greater than the negative predictive value for all questions. The CWC has strong reliability. Sensitivity and specificity suggested workers often indicated no problems with workstation setup when problems existed. The evidence suggests that while the CWC may not be valid when used alone, it may be a suitable adjunct to an ergonomic assessment completed by professionals.

  15. Implementation of an Oxytocin Checklist to Improve Clinical Outcomes.

    Oxytocin is one of the most common drugs administered in obstetrics. Since its designation as a high-alert medication by the Institute for Safe Medication Practices in 2007, there has been much attention to oxytocin administration during labor. Oxytocin is generally safe when administered correctly, but adverse perinatal outcomes can occur during uterine tachysystole. The purpose of this project was to evaluate and compare results of maternal and fetal outcomes of induction of labor for women at term prior to and after implementation of a newly developed oxytocin checklist. To evaluate the practice change associated with the implementation of the new oxytocin checklist, 200 cases based on retrospective medical record reviews were compared with 200 cases after implementation. Use of the checklist was associated with several significant clinical outcomes, including decreases in tachysystole, decreases in cesarean births for concern about fetal status based on electronic fetal monitoring data, decreases in length of first stage labor, and decreases in maximum dose of oxytocin. Results are similar to previous research. Early physician buy-in, clinical team education, and ongoing evaluation enhanced facilitation of the oxytocin checklist. Clinical outcomes were favorable.

    Many people experience irritability when manic, hypomanic, or depressed, yet its impact on illness severity and quality of life in bipolar and schizoaffective disorders is poorly understood. This study aimed to examine the relationship between irritability and symptom burden, functioning, quality of life, social support, suicidality, and overall illness severity in a naturalistic cohort of people with bipolar I or schizoaffective disorder. We used data from 239 adult outpatients with bipolar I or schizoaffective disorder in the Bipolar Comprehensive Outcomes Study (BCOS) - a non-interventional observational study with a 2-year follow-up period. Baseline demographic and clinical characteristics of participants with and without irritability were compared. A mixed-model repeated measures analysis was conducted to examine the longitudinal effect of irritability on clinical and quality-of-life variables over follow-up using significant baseline variables. At baseline, 54% of participants were irritable. Baseline irritability was associated with illness severity, mania, depression, psychotic symptoms, suicidality, poor functioning, and quality of life, but not diagnosis (schizoaffective/bipolar disorder). Participants with irritability were less likely to have a partner and perceived less adequate social support. On average, over follow-up, those with irritability reported more symptoms, functional impairment, and suicidality. Furthermore, the effects of irritability could not be fully explained by illness severity. Irritability was associated with more negative symptomatic, functional, and quality-of-life outcomes and suicidality. The identification, monitoring, and targeted treatment of irritability may be worth considering, to enhance health and wellbeing outcomes for adults with bipolar and schizoaffective disorders. © 2017 John Wiley & Sons A/S.

    2015-01-01

    Abstract We recently developed a novel Vitrigel‐eye irritancy test (EIT) method. The Vitrigel‐EIT method is composed of two parts, i.e., the construction of a human corneal epithelium (HCE) model in a collagen vitrigel membrane chamber and the prediction of eye irritancy by analyzing the time‐dependent profile of transepithelial electrical resistance values for 3 min after exposing a chemical to the HCE model. In this study, we estimated the predictive performance of Vitrigel‐EIT method by testing a total of 118 chemicals. The category determined by the Vitrigel‐EIT method in comparison to the globally harmonized system classification revealed that the sensitivity, specificity and accuracy were 90.1%, 65.9% and 80.5%, respectively. Here, five of seven false‐negative chemicals were acidic chemicals inducing the irregular rising of transepithelial electrical resistance values. In case of eliminating the test chemical solutions showing pH 5 or lower, the sensitivity, specificity and accuracy were improved to 96.8%, 67.4% and 84.4%, respectively. Meanwhile, nine of 16 false‐positive chemicals were classified irritant by the US Environmental Protection Agency. In addition, the disappearance of ZO‐1, a tight junction‐associated protein and MUC1, a cell membrane‐spanning mucin was immunohistologically confirmed in the HCE models after exposing not only eye irritant chemicals but also false‐positive chemicals, suggesting that such false‐positive chemicals have an eye irritant potential. These data demonstrated that the Vitrigel‐EIT method could provide excellent predictive performance to judge the widespread eye irritancy, including very mild irritant chemicals. We hope that the Vitrigel‐EIT method contributes to the development of safe commodity chemicals. Copyright © 2015 The Authors. Journal of Applied Toxicology published by John Wiley & Sons Ltd.

    BACKGROUND AND OBJECTIVES: Family-centered rounds (FCRs) have become standard of care, despite the limited evaluation of FCRs’ benefits or interventions to support high-quality FCR delivery. This work examines the impact of the FCR checklist intervention, a checklist and associated provider training, on performance of FCR elements, family engagement, and patient safety. METHODS: This cluster randomized trial involved 298 families. Two hospital services were randomized to use the checklist; 2 others delivered usual care. We evaluated the performance of 8 FCR checklist elements and family engagement from 673 pre- and postintervention FCR videos and assessed the safety climate with the Children’s Hospital Safety Climate Questionnaire. Random effects regression models were used to assess intervention impact. RESULTS: The intervention significantly increased the number of FCR checklist elements performed (β = 1.2, P < .001). Intervention rounds were significantly more likely to include asking the family (odds ratio [OR] = 2.43, P < .05) or health care team (OR = 4.28, P = .002) for questions and reading back orders (OR = 12.43, P < .001). Intervention families’ engagement and reports of safety climate were no different from usual care. However, performance of specific checklist elements was associated with changes in these outcomes. For example, order read-back was associated with significantly more family engagement. Asking families for questions was associated with significantly better ratings of staff’s communication openness and safety of handoffs and transitions. CONCLUSIONS: The performance of FCR checklist elements was enhanced by checklist implementation and associated with changes in family engagement and more positive perceptions of safety climate. Implementing the checklist improves delivery of FCRs, impacting quality and safety of care. PMID:28557720

    We describe a mobile digital checklist that we designed and developed for trauma resuscitation—a dynamic, fast-paced medical process of treating severely injured patients. The checklist design was informed by our analysis of user interactions with a paper checklist that was introduced to improve team performance during resuscitations. The design process followed an iterative approach and involved several medical experts. We discuss design challenges in converting a paper checklist to its digital counterpart, as well as our approaches for addressing those challenges. While we show that using a digital checklist during a fast-paced medical event is feasible, we also recognize several design constraints, including limited display size, difficulties in entering notes about the medical process and patient, and difficulties in replicating user experience with paper checklists.

    Assessment of ocular irritancy is an international regulatory requirement and a necessary step in the safety evaluation of industrial and consumer products. Although a number of in vitro ocular irritation assays exist, none are capable of fully categorizing chemicals as a stand-alone assay. Therefore, the CEFIC-LRI-AIMT6-VITO CON4EI (CONsortium for in vitro Eye Irritation testing strategy) project was developed with the goal of assessing the reliability of eight in vitro/alternative test methods as well as establishing an optimal tiered-testing strategy. One of the in vitro assays selected was the validated SkinEthic™ Human Corneal Epithelium Eye Irritation Test method (SkinEthic™ HCE EIT). The SkinEthic™ HCE EIT has already demonstrated its capacity to correctly identify chemicals (both substances and mixtures) not requiring classification and labelling for eye irritation or serious eye damage (No Category). The goal of this study was to evaluate the performance of the SkinEthic™ HCE EIT test method in terms of the important in vivo drivers of classification. For the performance with respect to the drivers all in vivo Cat 1 and No Cat chemicals were 100% correctly identified. For Cat 2 chemicals the liquids and the solids had a sensitivity of 100% and 85.7%, respectively. For the SkinEthic™ HCE EIT test method, 100% concordance in predictions (No Cat versus No prediction can be made) between the two participating laboratories was obtained. The accuracy of the SkinEthic™ HCE EIT was 97.5% with 100% sensitivity and 96.9% specificity. The SkinEthic™ HCE EIT confirms its excellent results of the validation studies. Copyright © 2017.

    New experimental data show how chromosomal aberrations for low- and high-LET radiation are dependent on DSB repair deficiencies in wild-type, AT and NBS cells. We simulated the development of chromosomal aberrations in these cells lines in a stochastic track-structure-dependent model, in which different cells have different kinetics of DSB repair. We updated a previously formulated model of chromosomal aberrations, which was based on a stochastic Monte Carlo approach, to consider the time-dependence of DSB rejoining. The previous version of the model had an assumption that all DSBs would rejoin, and therefore we called it a time-independent model. The chromosomal-aberrations model takes into account the DNA and track structure for low- and high-LET radiations, and provides an explanation and prediction of the statistics of rare and more complex aberrations. We compared the program-simulated kinetics of DSB rejoining to the experimentally-derived bimodal exponential curves of the DSB kinetics. We scored the formation of translocations, dicentrics, acentric and centric rings, deletions, and inversions. The fraction of DSBs participating in aberrations was studied in relation to the rejoining time. Comparisons of simulated dose dependence for simple aberrations to the experimental dose-dependence for HF19, AT and NBS cells will be made.

Cartesian quanta and angular momentum classifications have their corresponding aberration classifications. The operation of concatenation of optical elements introduces a new operation between harmonic oscillator states.

    Checklists have been widely used in the aviation industry ever since aircraft operations became more complex than any single pilot could reasonably remember. More recently, checklists have found their way into medicine, where cognitive function can be compromised by stress and fatigue. The use of checklists in medical education has rarely been reported, especially in the basic sciences. We explored whether the use of a checklist in the gross anatomy laboratory would improve learning outcomes, dissection quality, and students' satisfaction in the first-year Human Structure didactic block at Mayo Medical School. During the second half of a seven-week anatomy course, dissection teams were each day given a hardcopy checklist of the structures to be identified during that day's dissection. The first half of the course was considered the control, as students did not receive any checklists to utilize during dissection. The measured outcomes were scored on four practice practical examinations and four dissection quality assessments, two each from the first half (control) and second half of the course. A student satisfaction survey was distributed at the end of the course. Examination and dissection scores were analyzed for correlations between practice practical examination score and checklist use. Our data suggest that a daily hardcopy list of anatomical structures for active use in the gross anatomy laboratory increases practice practical examination scores and dissection quality. Students recommend the use of these checklists in future anatomy courses. Copyright © 2011 American Association of Anatomists.

    Epidemiologic studies indicate that after using soaps and other personal care products, many consumers experience irritation. In 50% of the cases the feelings of skin dryness, itching, and stinging occur in the absence of visible signs of irritation. We sought to determine the relation between self-perceived sensory responses of panelists to cleansing products and clinical signs of irritation. A combination of exaggerated arm-washing methods was designed to induce clinical signs of irritation with psychometric techniques developed to quantify sensations. Two studies demonstrated that panelists could reproducibly differentiate between products on the basis of the sensations they felt and that there was a significant correlation (frequently r > 0.80) between these and the observable signs. In the case of skin dryness panelists differentiated products several washing cycles before observable differences were detected. Sensory evaluations of irritation yield additional information on soap and detergent irritancy beyond clinical observations and expand understanding of the irritation process.

    Skin may adapt to topical irritants through accommodation. This study focuses on long-term exposure to irritants and attempts to demonstrate accommodation. Sodium lauryl sulfate (SLS) induced irritant contact dermatitis at 3 concentrations (0.025% to 0.075%). Distilled water, acetone and an empty chamber served as controls. Experimental compounds were applied to forearms of 7 healthy volunteers for 24 hr before replacing by a fresh chamber for 6 non-consecutive weeks over 103 days. Possible accommodation was quantified by visual scoring (erythema and dryness) and by bioengineering parameters: transepidermal water loss (TEWL), capacitance, chromametry and laser Doppler flowmetry (LDF). Significant erythema, dryness, elevated TEWL, skin colour reflectance and LDF values occurred during the exposure periods. Upon repeat exposure, an immediate and augmented response in erythema, TEWL, skin colour reflectance and LDF developed. However, irritant skin changes were not sustained. Irritation parameters return to baseline after cessation of exposure. There was no evidence of sustained irritation or accommodation after the last exposure. Study findings do not document sustained accommodation or adaptive hyposensitivity after long-term repetitive irritant exposure under these test conditions. Alternative models should be developed to prove or disprove the accommodation hypothesis.

    To establish the inter-rater reliability of an observation-based ergonomics assessment checklist for computer workers. A 37-item (38-item if a laptop was part of the workstation) comprehensive observational ergonomics assessment checklist comparable to government guidelines and up to date with empirical evidence was developed. Two trained practitioners assessed full-time office workers performing their usual computer-based work and evaluated the suitability of workstations used. Practitioners assessed each participant consecutively. The order of assessors was randomised, and the second assessor was blinded to the findings of the first. Unadjusted kappa coefficients between the raters were obtained for the overall checklist and subsections that were formed from question-items relevant to specific workstation equipment. Twenty-seven office workers were recruited. The inter-rater reliability between two trained practitioners achieved moderate to good reliability for all except one checklist component. This checklist has mostly moderate to good reliability between two trained practitioners. Practitioner Summary: This reliable ergonomics assessment checklist for computer workers was designed using accessible government guidelines and supplemented with up-to-date evidence. Employers in Queensland (Australia) can fulfil legislative requirements by using this reliable checklist to identify and subsequently address potential risk factors for work-related injury to provide a safe working environment.

    Studies show that using surgical safety checklists (SSCs) reduces complications. Many believe SSCs accomplish this by enhancing teamwork, but evidence is limited. Our study sought to relate teamwork to checklist performance, understand how they relate, and determine conditions that affect this relationship. Using 2 validated tools for observing and coaching operating room teams, we evaluated the association between checklist performance with surgeon buy-in and 4 domains of surgical teamwork: clinical leadership, communication, coordination, and respect. Hospital staff in 10 South Carolina hospitals observed 207 procedures between April 2011 and January 2013. We calculated levels of checklist performance, buy-in, and measures of teamwork, and evaluated their relationship, controlling for patient and case characteristics. Few teams completed most or all SSC items. Teams more often completed items considered procedural "checks" than conversation "prompts." Surgeon buy-in, clinical leadership, communication, a summary measure of teamwork overall, and observers' teamwork ratings positively related to overall checklist completion (multivariable model estimates from 0.04, p < 0.05 for communication to 0.17, p < 0.01 for surgeon buy-in). All measures of teamwork and surgeon buy-in related positively to completing more conversation prompts; none related significantly to procedural checks (estimates from 0.10, p < 0.01 for communication to 0.27, p < 0.001 for surgeon buy-in). Patient age was significantly associated with completing the checklist and prompts (p < 0.05); only case duration was positively associated with performing more checks (p < 0.10). Surgeon buy-in and surgical teamwork characterized by shared clinical leadership, open communication, active coordination, and mutual respect were critical in prompting case-related conversations, but not in completing procedural checks. Findings highlight the importance of surgeon engagement and high-quality, consistent

    So-called aberration-free intraocular lenses (IOLs) are well established in modern cataract surgery. Usually, they are designed to perfectly refract a collimated light beam onto the focal point. We show how much aberration can be expected with such an IOL in a convergent light beam such as that found anterior to the human cornea. Additionally, the aberration in a collimated beam is estimated for an IOL that has no aberrations in the convergent beam. The convergent beam is modelled as the pencil of rays corresponding to the spherical wavefront resulting from a typical corneal power of 43m -1 . The IOLs are modelled as infinitely thin phase plates with 20m -1 optical power placed 5mm behind the cornea. Their aberrations are reported in terms of optical path length difference and longitudinal spherical aberration (LSA) of the marginal rays, as well as nominal spherical aberration (SA) calculated based on a Zernike representation of the wavefront-error at the corneal plane within a 6mm aperture. The IOL designed to have no aberrations in a collimated light beam has an optical path length difference of -1.8μm, and LSA of 0.15m -1 in the convergent beam of a typical eye. The corresponding nominal SA is 0.065μm. The IOL designed to have no aberrations in a convergent light beam has an optical path length difference of 1.8μm, and LSA of -0.15m -1 in the collimated beam. An IOL designed to have no aberrations in a collimated light beam will increase the SA of a patient's eye after implantation. Copyright © 2017. Published by Elsevier GmbH.

    Checklists have been recently introduced in the medical practice playing the role of summarized guidelines, streamlined for rapid consultations. However, there are still some barriers preventing their widespread diffusion. Those concern the representation, dissemination and update of their underlying knowledge, as well as the means currently adopted for their actual use, that is still mostly paper-based. In this paper we propose a new platform for the implementation and use of checklists. First, an editor supports domain experts in porting the checklist from the traditional paper-based format into an electronic one. Then, an application allows the distribution and usage of checklists on portable devices such as smartphones and tablets, exploiting their additional features in comparison with those made available by Personal Computers. The platform will be illustrated through some examples designed to support volunteers and paramedic staff in dealing with emergency situations.
