There has been an ongoing debate about the inconsistent effects of heterogeneous ability grouping on students in small group work such as project-based learning. The present research investigated the roles of group heterogeneity and processes in project-based learning. At the student level, we examined the interaction effect between students' within-group achievement and group processes on their self- and collective efficacy. At the group level, we examined how group heterogeneity was associated with the average self- and collective efficacy reported by the groups. The participants were 1,921 Hong Kong secondary students in 367 project-based learning groups. Student achievement was determined by school examination marks. Group processes, self-efficacy and collective efficacy were measured by a student-report questionnaire. Hierarchical linear modelling was used to analyse the nested data. When individual students in each group were taken as the unit of analysis, results indicated an interaction effect of group processes and students' within-group achievement on the discrepancy between collective- and self-efficacy. When compared with low achievers, high achievers reported lower collective efficacy than self-efficacy when group processes were of low quality. However, both low and high achievers reported higher collective efficacy than self-efficacy when group processes were of high quality. With 367 groups taken as the unit of analysis, the results showed that group heterogeneity, group gender composition and group size were not related to the discrepancy between collective- and self-efficacy reported by the students. Group heterogeneity was not a determinant factor in students' learning efficacy. Instead, the quality of group processes played a pivotal role because both high and low achievers were able to benefit when group processes were of high quality.

Although systems to collect information about suspected adverse drug reactions (ADRs) were established in many countries and by the WHO in the 1960s, few studies have examined reported ADRs related to national income. The aim of the study was to characterize ADRs reported to the WHO-ADR database, VigiBase™, and to relate data to national income. We analysed ADR reports submitted to VigiBase™ from 2000 to 2009 with respect to reporting rate, age and sex of patient, type, seriousness and medications. Reports were also analysed with respect to national income level, classified in accordance with the World Bank definition: low, lower-middle, upper-middle and high. We analysed 1,359,067 ADR reports including 3,013,074 ADRs. Overall, 16% of reports were serious and 60% were reported for females. High-income countries had the highest ADR reporting rates (range 3-613 reports/million inhabitants/year) and low-income countries the lowest (range 0-21). Distribution of ADRs across income groups with respect to age group, seriousness and sex was non-significant. Overall, the majority of ADRs were reported for nervous system medications, followed by cardiovascular medicines. Low-income countries reported relatively more ADRs for antiinfectives for systemic use than high-income countries, and high-income countries reported more ADRs for antineoplastic and immunomodulating agents than lower-income groups. This study showed that high-income countries had the highest ADR reporting rates and low-income countries the lowest, with large variations across countries in each group. Significant differences in ADR reporting rates were only found for ADRs of the type 'skin and subcutaneous tissue disorders' and for the therapeutic groups 'antiinfectives for systemic use' and 'antineoplastic and immunomodulation agents'. To strengthen ADR reporting rates, especially in low-income countries, more research is needed about the impact of organizational structures and economic resources of national pharmacovigilance centres and ADR reporting practices on the large variations in ADR reporting rates within income groups.

Self-regulated learning (SRL) is a multi-dimensional construct that has been difficult to operationalize using traditional, variable-centered methodologies. The current paper takes a person-centered approach to the study of SRL in a sample of 205 high-school students. Using latent profile analysis on self-reports of seven aspects of SRL, three groups were identified: high SRL, low SRL, and average SRL. Student self-reports of goal orientation were used as validation for the profile solution, with the high academic self- regulation group reporting the highest levels of mastery orientation while the low self-regulation group reported highest levels of avoidant orientation. Profiles were also compared on independently collected, behavioral measures of study behaviors, with the highly self-regulated group tending to study more material and for a longer time than less self-regulated individuals.

This research aimed to characterize patterns of emotional reactivity and dysregulation in borderline personality, depression, and their co-occurrence. In Study 1, 488 young adult women from the community were categorized into four groups based on self-reported major depressive disorder (MDD) and borderline personality disorder (BPD) symptoms (Low BPD/Low MDD; Low BPD/High MDD; High BPD/Low MDD; High BPD/High MDD). Immediate and prolonged subjective emotional reactivity to a laboratory stressor were assessed, and participants completed self-report and behavioral measures of emotion dysregulation. Study 2 extended these findings, examining emotional reactivity and dysregulation in a clinical population of 176 substance dependent patients with diagnoses of BPD and MDD and including a biological index of emotional reactivity. Results revealed greater prolonged fear reactivity in the High BPD/High MDD (vs. Low BPD/Low MDD) group in Study 1, and greater prolonged anxiety and negative affect reactivity in both High BPD groups (vs. Low BPD/Low MDD and Low BPD/High MDD groups) in Study 2 (but no differences in cortisol reactivity). Results also demonstrated greater subjective (but not behavioral) emotion dysregulation in the High BPD/High MDD (vs. Low BPD/Low MDD) group in Study 1 and both High BPD groups (vs. both Low BPD groups) in Study 2. Finally, the High BPD/High MDD group reported greater difficulties controlling impulsive behaviors compared with all other groups in Study 1 and the Low BPD groups in Study 2. Findings suggest that BPD pathology (but not MDD pathology alone) is characterized by greater prolonged emotional (especially anxiety/fear-related) reactivity and heightened emotion dysregulation.

Adolescent peer group self-identification refers to adolescents' affiliation with reputation-based peer groups such as "Goths" or "Jocks." These groups tend to vary on normative characteristics, including the group members' attitudes and behaviors. This article examined whether adolescents' baseline peer group self-identification predicted their self-reported relational and physical aggression 1 year later. Self-report data were collected from 1614 students from 9 regular and 9 continuation (alternative) high schools in Southern California, at baseline and 1-year follow-up. Subjects' mean baseline age was 15.21 years (SD = 1.18) and 51.6% of the subjects were female. Findings indicated that compared with self-identified "Regular" or "Normal" students, adolescents who identified with high-risk peer groups (eg, "Druggies,"Goths") tended to report higher relational and physical aggression 1 year later, controlling for baseline aggression and demographic variables. In addition, adolescents' self-identification with high-status peer groups (eg, "Jocks,"Populars") was predictive of higher relational aggression 1 year later. Gender and school type (ie, regular vs continuation) were not found to moderate these effects. It appears that peer group self-identification is a salient predictor of physical and relational aggression across gender and school type. Adolescents who identify with high-risk peer groups tend to report higher levels of physical as well as relational aggression in the future. In addition, adolescents who affiliate with elite groups tend to become more relationally aggressive over time. School-based prevention programs targeting aggression may benefit from addressing the impacts of peer group self-identification on adolescents' aggressive behavior.

Local information processing in 42 adults with high functioning autism, 41 adults with Asperger syndrome and 41 neurotypical adults was examined. Contrary to our expectations, the disorder groups did not outperform the neurotypical group in the neuropsychological measures of local information processing. In line with our hypotheses, the self-reports did show higher levels of local information processing and a stronger tendency to use systemizing strategies in the two disorder groups. Absent and weak correlations were found between the self-reports and the two neuropsychological tasks in the three groups. The neuropsychological tests and the self-reports seem to measure different underlying constructs. The self-reports were most predictive of the presence of an autism spectrum diagnosis.

To clarify the relationship between social phobia and shyness, this study examined the characteristics of highly shy persons with social phobia, highly shy persons without social phobia, and non-shy persons. Those with social phobia reported more symptomatology, more functional impairment, and a lower quality of life than those without social phobia. About one-third of the highly shy without social phobia reported no social fears, highlighting heterogeneity of the shy. The social phobia group reported similar levels of anxiety as the shy without social phobia during analogue conversation tasks, but they reported more anxiety during a speech task. The social phobia group performed less effectively across tasks than those without social phobia. All groups' perceptions of anxiety and effectiveness during behavioral tasks were consistent with ratings of independent observers. None of the groups differed on psychophysiological measures. Results are discussed in the context of theoretical models of social phobia.

Physical aggression declines for the majority of children from preschool to elementary school. Although this desistance generally continues during adolescence and early adulthood, a small group of children maintain a high level of physical aggression over time and develop other serious overt and covert antisocial behaviors. Typically, researchers have examined relations of developmental changes in physical aggression to later violence with teachers' or mothers' reports on surveys. Little is known about the degree to which children's self-reported physical aggression predicts later antisocial behavior. The longitudinal study in this article had a staggered, multiple cohort design. Measures of physical aggression were collected through self- and mother reports from age 11–14 years, which were used to construct trajectory groups (attrition was 6 and 14% from age 11–14, respectively, for self- and mother reports). Overt and covert antisocial behaviors were self-reported at age 18–19 years (attrition was 36% from age 11 to 18–19). Four trajectory groups (low stable, 11%; moderate-low declining, 34%; moderate declining, 39%; high stable, 16%) were identified from self-reports, whereas three trajectories (low declining, 33%; moderate declining, 49%; high stable, 18%) were identified from mothers' ratings. We examined the prediction of overt and covert antisocial behaviors in early adulthood from the high stable and the moderate declining trajectories. According to both informants, higher probability of belonging to the high stable group was associated with higher overt and covert antisocial behavior, whereas higher probability of belonging to the moderate declining group was associated with higher covert antisocial behavior. Our results support the value of children's as well as mothers' reports of children's aggression for predicting different types of serious antisocial behavior in adulthood. PMID:20878197

Meade, Karen Marie

The purpose of this study was to identify conceptual and attitudinal effects of inquiry learning in technology-based undergraduate chemistry laboratories. There were 428 participants who were registered in general chemistry laboratory at the University of Iowa in the Spring of 2002. Conceptual and attitudinal pretest and posttest results were quantitative in nature. Qualitative results were collected from questionnaires and focus groups. Quantitative data were analyzed using a repeated measures analysis of variance to identify differences between treatment groups. A high-inquiry treatment group was open-ended and required student decisions regarding data collection, data representation, and interpretation. The low-inquiry treatment involved collaboration and traditional learning strategies. Major findings of this study were: (1) Pretest to posttest conceptual gains were significant for both treatment groups. Low-inquiry students performed significantly better on exploration questions than high-inquiry students. (2) Process skills developed at higher levels for high-inquiry students than low-inquiry students. (3) Positive attitudes decreased significantly for all students from pretest to posttest. More favorable attitudes toward science enjoyment and the ability to do well in science were found for high-inquiry students. More favorable attitudes toward science enjoyment and the ability to do well in science were found for low-inquiry males and high-inquiry females. (4) More favorable attitudes toward the nature of science caused by use of the learning cycle were reported by high-inquiry students. (5) Low-inquiry students reported more favorable attitudes toward technologies in the laboratory than did high-inquiry students. Favorable attitudes toward the use of infrared spectrometers and unfavorable attitudes toward the use of pH meters were reported by both treatment groups. (6) More formal reasoning skills were reported by high-inquiry students. Both groups reported that looking for patterns was a common theme in the laboratories. Hypotheses were reported as rarely used by both treatment groups. These findings are significant because they indicate that inquiry activities positively affect attitudes toward science, gender equality, and contribute to the development of formal reasoning skills and process skills.

This study examines positive dispositions reported by middle school and high school students participating in programs that feature STEM-related activities. Middle school students participating in school-to-home hands-on energy monitoring activities are compared to middle school and high school students in a different project taking part in activities such as an after-school robotics program. Both groups are compared and contrasted with a third group of high school students admitted at the eleventh grade to an academy of mathematics and science. All students were assessed using the same science, technology, engineering and mathematics (STEM) dispositions instrument. Findings indicate that the after-school group whose participants self-selected STEM engagement activities, and the self-selected academy of mathematics and science group, each had highly positive STEM dispositions comparable to those of STEM professionals, while a subset of the middle school whole-classroom energy monitoring group that reported high interest in STEM as a career, also possessed highly positive STEM dispositions comparable to the STEM Professionals group. The authors conclude that several different kinds of hands-on STEM engagement activities are likely to foster or maintain positive STEM dispositions at the middle school and high school levels, and that these highly positive levels of dispositions can be viewed as a target toward which projects seeking to interest mainstream secondary students in STEM majors in college and STEM careers, can hope to aspire. Gender findings regarding STEM dispositions are also reported for these groups.

Although matrix-assisted laser desorption/ionisation, time-of-flight mass spectrometry (MALDI-TOF MS) has previously been reported for high throughput blood group genotyping, those reports are limited to only a few blood group systems. This review describes the development of a large cooperative Swiss-German project, aiming to employ MALDI-TOF MS for the molecular detection of the blood groups Rh, Kell, Kidd, Duffy, MNSs, a comprehensive collection of low incidence antigens, as well as the platelet and granulocyte antigens HPA and HNA, representing a total of 101 blood group antigens, encoded by 170 alleles, respectively. Recent reports describe MALDI-TOF MS as a technology with short time-to-resolution, ability for high throughput, and cost-efficiency when used in genetic analysis, including forensics, pharmacogenetics, oncology and hematology. Furthermore, Kell and RhD genotyping have been performed on fetal DNA from maternal plasma with excellent results. In summary, this article introduces a new technological approach for high throughput blood group genotyping by means of MALDI-TOF MS. Although all data presented are preliminary, the observed success rates, data quality and concordance with known blood group types are highly impressive, underlining the accuracy and reliability of this cost-efficient high throughput method.

Donovan, Kera L; Brassard, Marla R

2011-10-01

The primary research objective was to explore the relationship between trajectories of maternal verbal aggression (VA) experienced by low-income, community middle school students across a three-year period and outcomes that have been found to be related to VA in previous work, including a negative view of self and social problems. Longitudinal data were collected from 421 youth (51.8% male) attending two middle schools over 3 years using a multiple-informant survey design. K-means cluster analysis was used to identify trajectories of VA using youth ratings of the Conflict Tactics Scale: Parent-Child (Straus, Hamby, Finkelhor, Moore, & Runyan, 1998). Dependent variables were self-reported depression, self-esteem, delinquency, and peer victimization as well as peer-rated aggression and sensitive-isolated reputation. Four trajectory groups of VA were identified: Low Stable, Increasing, Decreasing, and High Stable. The 3-year average occurrence of VA was: 1.31, 9.18, 10.24, and 31.14 instances, respectively. Gender-specific MANOVAs revealed dramatic differences between the High Stable and Low Stable groups. High Stable boys reported significantly more depressive symptoms, delinquency, peer overt and relational victimization, and were less likely to have a sensitive/isolated reputation than Low Stable boys. High Stable girls reported significantly more depressive symptoms, low self-esteem, delinquency, peer overt and relational victimization and were rated by peers as having more aggressive/disruptive and relationally aggressive reputations than Low Stable girls. Girls in the High Stable group were more likely than other youth to report levels of depressive symptoms and delinquency >1 SD above the mean, while boys in the High Stable group were more likely to report levels of delinquency >1 SD above the mean. The Increasing and Decreasing groups also demonstrated significantly poorer functioning than the Low Stable group on most outcomes. Growth curve analysis revealed that VA showed a contemporaneous association with self-reported delinquency suggesting these factors are closely related. Any level of VA greater than the 1-2 instances per year reported by youth in the Low Stable group was associated with less favorable outcomes. Copyright Â© 2011 Elsevier Ltd. All rights reserved.

Although there is strong evidence that single physical, psychosocial and organisational risk factors are each independent predictors of low back symptoms (LBS), little is known about their combination/interaction, particularly in those working in developing countries. A total of 1294 Indonesian coal mining industry workers reported information about physical, psychosocial, and organisational factors using self-reported questionnaires and were placed into one of four combination exposure groups: 1) high physical (working with bent trunk; whole body vibration exposure; lifting) and high psychosocial (high effort; low reward; work stress), 2) high physical and low psychosocial, 3) low physical and high psychosocial, and 4) low physical and low psychosocial (as the reference group). The odds of LBS in the high physical and high psychosocial group was 5.15 times (95% confidence interval 2.69-9.86) that of the reference group. Psychosocial factors played a more important role than physical factors in increasing the likelihood of reporting LBS. Permanent and night shift workers were more likely to report LBS. These findings imply that efforts to reduce LBS in this workplace should address both psychosocial and physical factors but psychosocial factors should be the priority, with a special focus on permanent and night shift workers.
Role of gender norms and group identification on hypothetical and experimental pain tolerance.

Pool, Gregory J; Schwegler, Andria F; Theodore, Brian R; Fuchs, Perry N

2007-05-01

Previous research indicates that men typically tolerate more pain in experimental settings than women. One likely explanation for these group differences in pain tolerance is conformity to traditional, gender group social norms (i.e., the ideal man is masculine and tolerates more pain; the ideal woman is feminine and tolerates less pain). According to self-categorization theory, norms guide behavior to the degree that group members adopt the group identity. Therefore, high-identifying men are expected to conform to gender norms and tolerate more pain than high-identifying women who conform to different gender norms as a guide for their behavior. We conducted two studies to investigate whether gender group identification moderates individuals' conformity to pain tolerance and reporting norms. In the first study, participants indicated their gender identification and expected tolerance of a hypothetical painful stimulus. As anticipated, high-identifying men reported significantly greater pain tolerance than high-identifying women. No differences existed between low-identifying men and women. To determine if self-reported pain tolerance in a role-playing scenario corresponds to actual pain tolerance in an experimental setting, the second study examined pain tolerance to a noxious stimulus induced by electrical stimulation of the index finger. The experimental outcome revealed that high-identifying men tolerated more painful stimulation than high-identifying women. Further, high-identifying men tolerated more pain than low-identifying men. These results highlight the influence of social norms on behavior and suggest the need to further explore the role of norms in pain reporting behaviors.
Music Taste Groups and Problem Behavior.

Internalizing and externalizing problems differ by musical tastes. A high school-based sample of 4159 adolescents, representative of Dutch youth aged 12 to 16, reported on their personal and social characteristics, music preferences and social-psychological functioning, measured with the Youth Self-Report (YSR). Cluster analysis on their music preferences revealed six taste groups: Middle-of-the-road (MOR) listeners, Urban fans, Exclusive Rock fans, Rock-Pop fans, Elitists, and Omnivores. A seventh group of musically Low-Involved youth was added. Multivariate analyses revealed that when gender, age, parenting, school, and peer variables were controlled, Omnivores and fans within the Exclusive Rock groups showed relatively high scores on internalizing YSR measures, and social, thought and attention problems. Omnivores, Exclusive Rock, Rock-Pop and Urban fans reported more externalizing problem behavior. Belonging to the MOR group that highly appreciates the most popular, chart-based pop music appears to buffer problem behavior. Music taste group membership uniquely explains variance in both internalizing and externalizing problem behavior.

Lower urinary tract symptoms (LUTS) are common in postmenopausal women, and have been reported inversely associated with vitamin D intake and serum 25-hydroxyvitamin D (25(OH)D) levels. The aim of this study was to investigate if high dose vitamin D supplementation would affect LUTS in comparison to standard dose. In a randomized controlled study including 297 postmenopausal women with low bone mineral density, the participants were allocated to receive capsules of 20 000IU of vitamin D 3 twice a week (high dose group) or similar looking placebo (standard dose group). In addition, all the participants received 1g of calcium and 800IU of vitamin D daily. A validated questionnaire regarding LUTS was filled in at baseline and after 12 months. At baseline, 76 women in the high dose group and 82 in the standard dose group reported any LUTS. Levels of serum 25(OH)D increased significantly more in the high dose group (from 64.7 to 164.1nmol/l compared to from 64.1 to 81.8nmol/l, p<0.01). No differences between the groups were seen regarding change in LUTS except for a statistically significant reduction in the reported severity of urine incontinence in the high dose group as compared to the standard dose group after one year (p<0.05). The results need confirmation in a study specifically designed for this purpose. Copyright © 2017 Elsevier Ltd. All rights reserved.

Addictive behaviors are accompanied by a lack of inhibitory control, specifically when individuals are confronted with substance-related cues. Thus, we expected women with symptoms of food addiction to be impaired in inhibitory control, when confronted with palatable, high-calorie food-cues. Female college students (N=50) were divided in low and high food addiction groups based on the symptom count of the Yale Food Addiction Scale. Participants performed a Go/No-go-task with high-calorie food-cues or neutral pictures presented behind the targets. Self-reported impulsivity was also assessed. The high food addiction group had faster reaction times in response to food-cues as compared to neutral cues and reported higher attentional impulsivity than the low food addiction group. Commission and omission errors did not differ between groups or picture types. Hence, women with food addiction symptoms reported higher attentional impulsivity and reacted faster in response to food-cues, although neither increased self-reported motor impulsivity nor impaired behavioral inhibition was found. Food addiction symptoms seem to be related to attentional aspects of impulsivity but not other facets of impulsivity. Copyright © 2012 Elsevier Ltd. All rights reserved.

Pain can be influenced by its social context. We aimed to examine under controlled experimental conditions how empathy from a partner and personal attachment style affect pain report, tolerance, and facial expressions of pain. Fifty-four participants, divided into secure, anxious, and avoidant attachment style groups, underwent a cold pressor task with their partners present. We manipulated how much empathy the participants perceived that their partners had for them. We observed a significant main effect of perceived empathy on pain report, with greater pain reported in the high perceived empathy condition. No such effects were found for pain tolerance or facial display. We also found a significant interaction of empathy with attachment style group, with the avoidant group reporting and displaying less pain than the secure and the anxious groups in the high perceived empathy condition. No such findings were observed in the low empathy condition. These results suggest that empathy from one's partner may influence pain report beyond behavioral reactions. In addition, the amount of pain report and expression that people show in high empathy conditions depends on their attachment style. Perspective Believing that one's partner feels high empathy for one's pain may lead individuals to rate the intensity of pain as higher. Individual differences in attachment style moderate this empathy effect. PMID:24953886

We used a questionnaire to identify university students with self-reported difficulties in reading acquisition during elementary school (self-report; n=31). The performance of the self-report group on standardized measures of word and non-word reading and fluency, passage comprehension and reading rate, and phonological awareness was compared to that of two other groups of university students: one with a recent diagnosis (diagnosed; n=20) and one with no self-reported reading acquisition problems (comparison group; n=33). The comparison group outperformed both groups with a history of reading difficulties (self-report and diagnosed) on almost all measures. The self-report and diagnosed groups performed similarly on most tasks, with the exception of untimed reading comprehension (better performance for diagnosed) and reading rate (better performance for self-report). The two recruitment methods likely sample from the same underlying population but identify individuals with different adaptive strategies.

The goal of this study was to characterize changes in daily fatigue in women undergoing chemotherapy for breast cancer. We examined whether there are subgroups of patients with distinct fatigue trajectories and explored potential psychosocial and biomedical predictors of these subgroups. Participants were 77 women with breast cancer receiving adjuvant chemotherapy with AC-T (2-week cycle) and TC or TCH (3-week cycle) regimens. They completed 28 daily ratings online using an adapted version of the Patient-Reported Outcomes Measurement Information System (PROMIS®) fatigue instrument. Both regimens followed an "inverted-U-shaped" fatigue pattern over approximately 2 weeks. Growth mixture modeling identified three patient subgroups with distinct trajectories. Fatigue scores in the "low fatigue" group (23 %) increased following the infusion and quickly abated. The "transient fatigue" (27 %) group had a very pronounced increase. Patients in the "high fatigue" (50 %) group reported consistently elevated fatigue with a relatively small increase. Demographic and medical variables were not associated with fatigue trajectory. Patients in the "high fatigue" group reported significantly poorer physical, emotional, and social functioning, poorer general health, and more depressed mood than patients in the "low fatigue" group. The "transient fatigue" group reported significantly better physical and social functioning than the "high fatigue" group, but emotional distress and depression similar to the "high fatigue" group. The identification of patient subgroups with distinct fatigue trajectories during chemotherapy is an essential step for developing preventative strategies and tailored interventions. Our results suggest that different trajectories are associated with patients' psychosocial and general health.

The Behavioral Risk Factor Surveillance System (BRFSS) survey is used to estimate chronic obstructive pulmonary disease (COPD) prevalence and could be expanded to describe respiratory symptoms in the general population and to characterize persons with or at high risk for the disease. Tobacco duration and respiratory symptom questions were added to the 2012 South Carolina BRFSS. Data concerning sociodemographics, chronic illnesses, health behaviors, and respiratory symptoms were collected in 9438 adults ≥ 35 years-old. Respondents were categorized as having COPD, high risk, or low risk for the disease. High risk was defined as no self-reported COPD, ≥ 10 years’ tobacco use, and ≥ 1 respiratory symptom (frequent productive cough or shortness of breath (SOB), or breathing problems affecting activities). Prevalence of self-reported and high-risk COPD were 9.1% and 8.0%, respectively. Overall, 17.3%, 10.6%, and 5.2% of all respondents reported activities limited by breathing problems, frequent productive cough, and frequent SOB, respectively. The high-risk group was more likely than the COPD group to report a productive cough and breathing problems limiting activities as well as being current smokers, male, and African-American. Health impairment was more severe in the COPD than the high-risk group, and both were worse than the low-risk group. Conclusions Persons at high risk for COPD share many, but not all, of the characteristics of persons diagnosed with the disease. Additional questions addressing smoking duration and respiratory symptoms in the BRFSS identifies groups at high risk for having or developing COPD who may benefit from smoking cessation and case-finding interventions.

2009-01-01

To clarify the relationship between social phobia and shyness, this study examined the characteristics of highly shy persons with social phobia, highly shy persons without social phobia, and non-shy persons. Those with social phobia reported more symptomatology, more functional impairment, and a lower quality of life than those without social phobia. About one-third of the highly shy without social phobia reported no social fears, highlighting heterogeneity of the shy. The social phobia group reported similar levels of anxiety as the shy without social phobia during analogue conversation tasks, but they reported more anxiety during a speech task. The social phobia group performed less effectively across tasks than those without social phobia. All groups’ perceptions of anxiety and effectiveness during behavioral tasks were consistent with ratings of independent observers. None of the groups differed on psychophysiological measures. Results are discussed in the context of theoretical models of social phobia. PMID:19028075

Self-reports of safe driving behaviors in relationship to sex, age, education and income in the US adult driving population.

2001-01-01

This study analyzed the data of a health and safety survey conducted on a representative sample of the adult driving population. The analysis focused on the relationships between self-reported safe driving behaviors (including belt use, observing speed limits, and abstaining from drinking and driving), and demographic characteristics (including sex, age, education and income). The results showed that the three behaviors are quite independent of each other, and, contrary to some stereotypes, there is no single high-risk group that is most likely to violate all three safe driving behaviors. The only consistent effect was that of sex: women reported higher observance rates of all three behaviors. Reported use of safety belts increases with age and education for both men and women. However while for women the reported use increases with income, for males the reported use does not change with income. Complete avoidance of drinking and driving was reported by most drivers in all groups, and the high rates hardly varied across the different age, education, and income groups. The number of people who reported that they observe the speed limit all the time increased with age, but decreased with increasing education and income. The results have implications for identifying violation-specific high-risk groups, and stressing different factors for each.

The goal of the STAR (STrengthening Altitude Research) initiative was to produce a uniform set of key elements for research and reporting in clinical high-altitude (HA) medicine. The STAR initiative was inspired by research on treatment of cardiac arrest, in which the establishment of the Utstein Style, a uniform data reporting protocol, substantially contributed to improving data reporting and subsequently the quality of scientific evidence. The STAR core group used the Delphi method, in which a group of experts reaches a consensus over multiple rounds using a formal method. We selected experts in the field of clinical HA medicine based on their scientific credentials and identified an initial set of parameters for evaluation by the experts. Of 51 experts in HA research who were identified initially, 21 experts completed both rounds. The experts identified 42 key parameters in 5 categories (setting, individual factors, acute mountain sickness and HA cerebral edema, HA pulmonary edema, and treatment) that were considered essential for research and reporting in clinical HA research. An additional 47 supplemental parameters were identified that should be reported depending on the nature of the research. The STAR initiative, using the Delphi method, identified a set of key parameters essential for research and reporting in clinical HA medicine.
The SOS Suicide Prevention Program: Further Evidence of Efficacy and Effectiveness.

Schilling, Elizabeth A; Aseltine, Robert H; James, Amy

2016-02-01

This study replicated and extended previous evaluations of the Signs of Suicide (SOS) prevention program in a high school population using a more rigorous pre-test post-test randomized control design than used in previous SOS evaluations in high schools (Aseltine and DeMartino 2004; Aseltine et al. 2007). SOS was presented to an ethnically diverse group of ninth grade students in technical high schools in Connecticut. After controlling for the pre-test reports of suicide behaviors, exposure to the SOS program was associated with significantly fewer self-reported suicide attempts in the 3 months following the program. Ninth grade students in the intervention group were approximately 64% less likely to report a suicide attempt in the past 3 months compared with students in the control group. Similarly, exposure to the SOS program resulted in greater knowledge of depression and suicide and more favorable attitudes toward (1) intervening with friends who may be exhibiting signs of suicidal intent and (2) getting help for themselves if they were depressed or suicidal. In addition, high-risk SOS participants, defined as those with a lifetime history of suicide attempt, were significantly less likely to report planning a suicide in the 3 months following the program compared to lower-risk participants. Differential attrition is the most serious limitation of the study; participants in the intervention group who reported a suicide attempt in the previous 3 months at baseline were more likely to be missing at post-test than their counterparts in the control group.

Adolescent traumatic brain injury (TBI) contributes to deficits in executive functioning and behavior, but few evidence-based treatments exist. We conducted a randomized clinical trial comparing Teen Online Problem Solving with Family (TOPS-Family) with Teen Online Problem Solving with Teen Only (TOPS-TO) or the access to Internet Resources Comparison (IRC) group. Children, aged 11 to 18 years, who sustained a complicated mild-to-severe TBI in the previous 18 months were randomly assigned to the TOPS-Family (49), TOPS-TO (51), or IRC group (52). Parent and self-report measures of externalizing behaviors and executive functioning were completed before treatment and 6 months later. Treatment effects were examined using linear regression models, adjusting for baseline symptom levels. Age, maternal education, and family stresses were examined as moderators. The TOPS-Family group had lower levels of parent-reported executive dysfunction at follow-up than the TOPS-TO group, and differences between the TOPS-Family and IRC groups approached significance. Maternal education moderated improvements in parent-reported externalizing behaviors, with less educated parents in the TOPS-Family group reporting fewer symptoms. On the self-report Behavior Rating Inventory of Executive Functions, treatment efficacy varied with the level of parental stresses. The TOPS-Family group reported greater improvements at low stress levels, whereas the TOPS-TO group reported greater improvement at high-stress levels. The TOPS-TO group did not have significantly lower symptoms than the IRC group on any comparison. Findings support the efficacy of online family problem solving to address executive dysfunction and improve externalizing behaviors among youth with TBI from less advantaged households. Treatment with the teen alone may be indicated in high-stress families.

In this longitudinal study, we disentangled within- and between-persons effects in the relationship between university students' status in their drinking group and alcohol-related behavior. We further examined the role of self-perceived and peer-reported status, with the hypothesis that only when students' peers reported them as of a higher status, and they were aware of their high status (via self-report), would they experience increased heavy episodic drinking (HED). University students (N = 118; Mage = 19.40, SD = 1.49; 60.2% women) were recruited in their natural drinking groups (N = 27). All group members completed surveys at 3 time points during the school year, each 2 months apart. We fitted a taxonomy of multilevel growth curve models predicting students' self-reported HED and the extent to which they encouraged other group members to consume alcohol (peer-reported). Between-persons results demonstrated that students who reported higher status compared to their group members experienced more HED on average and students who were peer-reported as of a higher status relative to their group members played a more salient role in encouraging others to drink. Notably, and consistent with hypotheses, a within-person interaction revealed that at time points when students were higher in peer-reported status relative to their average, and they were aware of their increase in status (via self-reports), they also engaged in more HED. Results emphasize the importance of considering within-person effects and highlight the need for university alcohol-prevention programming to focus on students' status-related motives and concerns.

Total knee arthroplasty (TKA) is an effective treatment to relieve pain and restore function in patients with advanced knee osteoarthritis. TKA utilization is growing rapidly, and the appropriateness of current TKA use is of great interest. We examined patient-reported preoperative pain and function profiles to understand symptom severity at the time of TKA decision. Data were from the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement. We included patients undergoing primary, unilateral TKAs between 2011 and 2014 for osteoarthritis and had data on the Knee Injury and Osteoarthritis Outcome Score (KOOS) pain and Short-Form 36-item Physical Component Summary (PCS) score. We compared patient profiles across groupings by symptoms: (1) little pain and high function (KOOS ≥70, PCS ≥40); (2) little pain but poor function (KOOS ≥70, PCS <40); (3) high pain but high function (KOOS <70, PCS ≥40); and (4) high pain and poor function (KOOS <70, PCS <40). Of 6936 patients, 77% had high pain and poor function (group 4), 19% had high pain "or" poor function (groups 2-3), and 5% had little pain and high function before TKA (group 1). In group 1, 86% were constantly aware of their knee problem, 48% reported pain daily yet 5% experienced severe or extreme pain on stairs, and 1% pain in bed. Over half had a lot of limitations in vigorous activities. Compared with group 4, group 1 were older, less obese, more educated, and included more men and people reporting being healthy, less disabled, and happy (P < .05 for all). Most patients undergoing TKAs had significant pain and/or poor function. Our results provide critical information given the current debate of potentially inappropriate TKA utilization in the United States. Copyright © 2016 Elsevier Inc. All rights reserved.

Crash rates among teenagers are highly elevated during the first months of licensure. Parent-imposed driving restrictions on initial driving privileges can reduce exposure to high-risk driving conditions, thus reducing crash risk while teens' driving proficiency develops. This report describes the effect of the Checkpoints Program on driving limits and outcomes. Connecticut teens who obtained a learners permit over a 9-month period were recruited, providing a final sample of 3743 who obtained driver licenses. Families were randomized to the intervention or comparison condition. Intervention families received by mail a series of persuasive communications related to high-risk teen driving and a parent-teen driving agreement, while comparison families received on the same schedule general information on driving and vehicle maintenance. Relative to the comparison group, teens and parents in the Checkpoints Program reported significantly greater limits on high-risk teen driving conditions at licensure, 3-, and 6-months post-licensure; and intervention teens reported significantly less risky driving at each reporting period. By the 12-month follow up teens in the intervention group were significantly less likely than those in the comparison group to have had a traffic violation. However, no treatment group effect was found for crashes. This is the first study to report significant effects on teen driving behavior and performance of education designed to increase parental-imposed teen driving limits.

Bullying involvement is prevalent among children and adolescents with autism spectrum disorder (ASD). This study examined the effects of theory of mind performance training (ToMPT) on reducing bullying involvement in children and adolescents with high-functioning ASD. Children and adolescents with high-functioning ASD completed ToMPT (n = 26) and social skills training (SST; n = 23) programs. Participants in both groups and their mothers rated the pretraining and posttraining bullying involvement of participants on the Chinese version of the School Bullying Experience Questionnaire. The paired t test was used to evaluate changes in bullying victimization and perpetration between the pretraining and posttraining assessments. Furthermore, the linear mixed-effect model was used to examine the difference in the training effect between the ToMPT and SST groups. The paired t test indicated that in the ToMPT group, the severities of both self-reported (p = .039) and mother-reported (p = .003) bullying victimization significantly decreased from the pretraining to posttraining assessments, whereas in the SST group, only self-reported bullying victimization significantly decreased (p = .027). The linear mixed-effect model indicated that compared with the SST program, the ToMPT program significantly reduced the severity of mother-reported bullying victimization (p = .041). The present study supports the effects of ToMPT on reducing mother-reported bullying victimization in children and adolescents with high-functioning ASD.

This paper investigates sickness presence (SP) among students. The research questions asked are: What is the distribution of SP among students in Norwegian secondary school? What characterises students with high SP in Norwegian secondary schools? A cross-sectional survey conducted in 10th grade in lower secondary school (LSS) and level 2 in upper secondary school (USS). The study was conducted using multivariate binomial logistic regression analysis. The survey was administered to 66 schools, and 2 or 3 classes participated at each school. The response rate was 84% in LSS (n=1880) and 81% in USS (n=1160). The paper provides information about the distribution of SP in secondary schools. The paper also examines which factors influence high SP. 75% of students in LSS and 80% of students in USS reported SP in the previous school year. 24% of students in LSS and 33% of students in USS reported high SP (4 episodes or more). Students with high absence from school were more likely to report high SP (ORLSS=1.7, ORUSS=2.0) than those with low/no absence. Girls were more likely to report high SP (ORLSS=1.5, ORUSS=1.5) than boys. In LSS, students with high school motivation reported high SP more often than students with low/medium motivation. In USS, students in vocational studies programmes reported high SP more often than students in general/academic studies programmes. Some SP during a school year may be more common than no SP. Gender, absence, motivation and education programme were important factors for high SP in secondary school. Published by the BMJ Publishing Group Limited.

Capability beliefs on, and use of evidence-based practice among four health professional and student groups in geriatric care: A cross sectional study

PubMed Central

2018-01-01

Implementation of evidence-based practice (EBP) is a complex task. This study, conducted in an acute geriatric setting, aims to compare self-reported capability beliefs on EBP between health professionals and students, and to compare the use of EBP between health professional groups. Occupational therapists, physicians, physiotherapists and registered nurses with three or more months’ employment, and all students from the occupational therapy, medical, physiotherapy and nursing programs, who had conducted workplace learning at the department, were invited. Data on capability beliefs and use of EBP were collected using the Evidence-based Practice Capabilities Beliefs Scale assessing six activities of EBP: formulate questions; search databases; search other sources; appraise research reports; participate in implementation in practice; and participate in evaluation. Descriptive and inferential statistics were used. Capability beliefs on EBP: The health professionals (n = 101; response rate 80%) reported high on search other sources but less on appraise research reports. The students (n = 124; response rate 73%) reported high on all EBP activities. The health professionals reported significantly higher on search other sources than the students. The students reported significantly higher on formulate questions and appraise research reports than the health professionals. No significant differences were identified between the health professional groups or between the student groups. Use of EBP: Health professionals reported wide-ranging use from several times each month to once every six months. The physicians reported significantly more frequent use than registered nurses and occupational therapists. Health professionals supervising students reported more frequent use of appraise research reports than the non-supervising group. There is a need for improving the use of EBP, particularly among registered nurses and occupational therapists. Supervision of students might enhance the motivation among staff to increase the use of EBP and students’ high EBP capability beliefs might inspire staff in this matter. PMID:29444179

Is High Sexual Desire a Risk for Women's Relationship and Sexual Well-Being?

PubMed

Štulhofer, Aleksandar; Bergeron, Sophie; Jurin, Tanja

2016-09-01

Historically, women's sexual desire has been deemed socially problematic. The growing popularity of the concept of hypersexuality-which lists high sexual desire among its core components-poses a risk of re-pathologizing female sexual desire. Data from a 2014 online survey of 2,599 Croatian women aged 18-60 years was used to examine whether high sexual desire is detrimental to women's relationship and sexual well-being. Based on the highest scores on an indicator of sexual desire, 178 women were classified in the high sexual desire (HSD) group; women who scored higher than one standard deviation above the Hypersexual Disorder Screening Inventory mean were categorized in the hypersexuality (HYP) group (n = 239). Fifty-seven women met the classification criteria for both groups (HYP&HSD). Compared to other groups, the HSD was the most sexually active group. Compared to controls, the HYP and HYP&HSD groups-but not the HSD group-reported significantly more negative consequences associated with their sexuality. Compared to the HYP group, women with HSD reported better sexual function, higher sexual satisfaction, and lower odds of negative behavioral consequences. The findings suggest that, at least among women, hypersexuality should not be conflated with high sexual desire and frequent sexual activity.

Fathers, daughters, and self-objectification: does bonding style matter?

PubMed

Miles-McLean, Haley; Liss, Miriam; Erchull, Mindy J

2014-09-01

As women are exposed to objectification and the "male gaze," they self-objectify, which predicts negative psychological outcomes. Given the centrality of the "male gaze," positive father/child relationships may have a buffering effect. In this study, women (N=447) completed a survey measuring paternal bonding (care and overprotection), self-objectification, negative eating attitudes, and depression. Women were categorized into four groups based on bonding style. Analyses indicated an interaction such that women who reported high care and low overprotection reported the fewest negative eating attitudes. A path model was tested for each group. The fit of the high care/high overprotection group's model significantly differed from that of the high care/low overprotection group. The relationships between body surveillance and shame as well as between shame and negative eating attitudes were stronger in the former group. These findings suggest that caring but overprotective fathers may exacerbate the negative effects of body surveillance and shame. Copyright © 2014 Elsevier Ltd. All rights reserved.
Everyday Functioning and Cognitive Correlates in Healthy Older Adults with Subjective Cognitive Concerns

McAlister, Courtney; Schmitter-Edgecombe, Maureen

2016-01-01

Objective Few studies have examined functional abilities and complaints in healthy older adults with subjective cognitive concerns (SCC). The aims of this study were to assess everyday functioning in healthy older adults reporting high and low amounts of SCC, and examine cognitive correlates of functional abilities. Method Twenty-six healthy older adults with high SCC, and 25 healthy older adults with low SCC, as well as their knowledgeable informants completed the Instrumental Activities of Daily Living-Compensation (IADL-C), a questionnaire measure of everyday functioning. Results After controlling for depression, the high SCC group self-reported significantly more everyday difficulties on the IADL-C, including all subdomains. Compared to the low SCC group, informants for the high SCC group endorsed more difficulties on the IADL-C and specifically the social skills subdomain. For the high SCC group, poorer self-report of everyday functioning was related to poorer executive functioning and temporal order memory. Conclusions These findings indicate that there may be subtle functional changes that occur early in the spectrum of cognitive decline in individuals with high SCC, and these functional changes are evident to informants. Further work is needed to investigate whether individuals with both SCC and functional difficulties are at an even higher risk for progression to mild cognitive impairment. PMID:27240886
Intrusions in children's dietary recalls: the roles of BMI, sex, race, interview protocol, and social desirability.

2008-09-01

Dietary-reporting validation study data and school foodservice production records were used to examine intrusions (reports of uneaten items) in school meals in 24-h recalls. Fourth-grade children [20 low-BMI (> or = 5th and < 50th percentiles); 20 high-BMI (> or = 85th percentile); 50% boys; 75% black] were each observed eating two school meals (breakfast, lunch) and interviewed about the prior 24h that evening (24E) or the previous day the next morning (PDM). Social desirability was assessed. Intrusions were classified as stretches (on meal tray), internal confabulations (in school foodservice environment but not on meal tray), and external confabulations (not in school foodservice environment). For breakfast, reported items were less likely to be intrusions for black than white children, and for low-BMI boys than the other BMI-x-sex groups, and to be external confabulations for high-BMI girls than high-BMI boys. For lunch, reported items and intrusions were more likely to be stretches for 24E than PDM interviews. As social desirability increased, fewer items were reported for breakfast, and reported items and intrusions were more likely to be internal confabulations for lunch. For breakfast, compared to low-BMI girls, as social desirability increased, intruded amounts were larger for high-BMI boys and smaller for high-BMI girls. For lunch, intruded amounts were smaller for high-BMI girls than the other BMI-x-sex groups. Amounts reported were smaller for stretches than internal confabulations and external confabulations for breakfast, and external confabulations for lunch. To better understand intrusions, dietary-reporting validation studies are needed with larger samples by BMI-group, sex, and race.

Dietary-reporting validation study data and school foodservice production records were used to examine intrusions (reports of uneaten items) in school meals in 24-hour recalls. Fourth-grade children (20 low-body mass index [BMI; ≥5th and <50th percentiles]; 20 high-BMI [≥85th percentile];50% boys; 75% Black) were each observed eating two school meals (breakfast, lunch) and interviewed about the prior 24 hours that evening (24E) or the previous day the next morning (PDM). Social desirability was assessed. Intrusions were classified as stretches (on meal tray), internal confabulations (in school foodservice environment but not on meal tray), and external confabulations (not in school foodservice environment). For breakfast, reported items were less likely to be intrusions for Black than White children, and for low-BMI boys than the other BMI-x-sex groups, and to be external confabulations for high-BMI girls than high-BMI boys. For lunch, reported items and intrusions were more likely to be stretches for 24E than PDM interviews. As social desirability increased, fewer items were reported for breakfast, and reported items and intrusions were more likely to be internal confabulations for lunch. For breakfast, compared to low-BMI girls, as social desirability increased, intruded amounts were larger for high-BMI boys and smaller for high-BMI girls. For lunch, intruded amounts were smaller for high-BMI girls than the other BMI-x-sex groups. Amounts reported were smaller for stretches than internal confabulations and external confabulations for breakfast, and external confabulations for lunch. To better understand intrusions, dietary-reporting validation studies are needed with larger samples by BMI-group, sex, and race. PMID:18535542

To compare the intake of women who report varying levels of frequency of consuming food at commercial facilities outside the home. A 1-week descriptive study of dietary intake in women. Subjects completed daily diet records that included information regarding the source of the food eaten at each meal or snack. The sample was divided on the basis of the number of meals each subject reported obtaining from a commercial establishment outside the home. Of the 129 subjects, 56% (n = 72) reported eating out 5 times or less during the week of recording (Low Eating Out group) and the remainder (n = 57) reported eating out between 6 and 13 times (High Eating Out group) One hundred twenty-nine premenopausal women were recruited via community advertising for an investigation of health habits. This study was conducted in a midsouthern US city. Results were analyzed using independent sample t tests and chi 2 tests. Mean intake was compared for the groups. The High Eating Out group was found to be consuming significantly more total energy (2,057 kcal vs 1,769 kcal; P = .002), fat (79.5 g vs 60.6 g; P < .001), and sodium (3,299 mg vs 2,903 mg; P = .043) and marginally more carbohydrate (261.5 g vs 234.6 g; P = .055) and protein (71.5 g vs 65.4 g; P = .066). Total fiber or calcium intake did not differ between the groups. Our study demonstrates that women who report eating out a greater number of times per week report more total energy intake as well as higher fat and sodium intakes. However, the High Eating Out group did not consume significantly more fiber or calcium in the extra energy consumed.

Heavy alcohol use and its associated negative consequences continue to be an important health issue among adolescents. Of particular concern are risky drinking practices such as playing drinking games. Although retrospective accounts indicate that drinking game participation is common among high school students, it has yet to be assessed in current high school students. Utilizing data from high school students who reported current drinking game participation (n = 178), we used latent class analysis to investigate the negative consequences resulting from gaming and examined underlying demographic and alcohol-related behavioral characteristics of students as a function of the resultant classes. Three classes of “gamers” emerged: (1) a “lower-risk” group who had a lower probability of endorsing negative consequences compared to the other groups, (2) a “higher-risk” group who reported that they experienced hangovers and difficulties limiting their drinking, got physically sick, and became rude, obnoxious, or insulting, and (3) a “sexual regret” group who reported that they experienced poor recall and unplanned sexual activity that they later regretted. Although the frequency of participating in drinking games did not differ between these three groups, results indicated that the “lower-risk” group consumed fewer drinks in a typical gaming session compared to the other two groups. The present findings suggest that drinking games are common among high school students, but that mere participation and frequency of play is not necessarily the best indicator of risk. Instead, examination of other constructs such as game-related alcohol consumption, consequences, or psychosocial variables such as impulsivity may be more useful. PMID:23778317

Crowe, Michael L; LoPilato, Alexander C; Campbell, W Keith; Miller, Joshua D

2016-12-01

The present study hypothesized that there exist two distinct groups of entitled individuals: grandiose-entitled, and vulnerable-entitled. Self-report scores of entitlement were collected for 916 individuals using an online platform. Model-based cluster analyses were conducted on the individuals with scores one standard deviation above mean (n = 159) using the five-factor model dimensions as clustering variables. The results support the existence of two groups of entitled individuals categorized as emotionally stable and emotionally vulnerable. The emotionally stable cluster reported emotional stability, high self-esteem, more positive affect, and antisocial behavior. The emotionally vulnerable cluster reported low self-esteem and high levels of neuroticism, disinhibition, conventionality, psychopathy, negative affect, childhood abuse, intrusive parenting, and attachment difficulties. Compared to the control group, both clusters reported being more antagonistic, extraverted, Machiavellian, and narcissistic. These results suggest important differences are missed when simply examining the linear relationships between entitlement and various aspects of its nomological network.

In October 2006, the Chief Medical Officer (CMO) of England asked Professor Sir John Tooke to chair a High Level Group on Clinical Effectiveness in response to the chapter 'Waste not, want not' in the CMOs 2005 annual report 'On the State of the Public Health'. The high level group made recommendations to the CMO to address possible ways forward to improve clinical effectiveness in the UK National Health Service (NHS) and promote clinical engagement to deliver this. The report contained a short section on research needs that emerged from the process of writing the report, but in order to more fully identify the relevant research agenda Professor Sir John Tooke asked Professor Martin Eccles to convene an expert group – the Clinical Effectiveness Research Agenda Group (CERAG) – to define the research agenda. The CERAG's terms of reference were 'to further elaborate the research agenda in relation to pursuing clinically effective practice within the (UK) National Health Service'. This editorial presents the summary of the CERAG report and recommendations. PMID:19351400

Developmental Coordination Disorder (DCD) affects around 2-6% of the population and is diagnosed on the basis of poor motor coordination in the absence of other neurological disorders. Its psychosocial impact has been delineated in childhood but until recently there has been little understanding of the implications of the disorder beyond this. This study aims to focus on the longer term impact of having DCD in adulthood and, in particular, considers the effect of employment on this group in relation to psychosocial health and wellbeing. Self-reported levels of life satisfaction, general health and symptoms of anxiety and depression were investigated in a group of adults with a diagnosis of DCD and those with suspected DCD using a number of published self-report questionnaire measures. A comparison between those in and out of employment was undertaken. As a group, the unemployed adults with DCD reported significantly lower levels of life satisfaction. Whilst there was no significant difference between those who were employed and unemployed on General Health Questionnaire scores; both groups reported numbers of health related issues reflective of general health problems in DCD irrespective of employment status. While both groups reported high levels of depressive symptoms and rated their satisfaction with life quite poorly, the unemployed group reported significantly more depressive symptoms and less satisfaction. Additionally, the results identified high levels of self-reported anxiety in both groups, with the majority sitting outside of the normal range using the Hospital Anxiety and Depression Scale. These findings add to the small but increasing body of literature on physical and mental health and wellbeing in adults with DCD. Furthermore, they are the first to provide insight into the possible mediating effects of employment status in adults with DCD. Copyright © 2013 Elsevier Ltd. All rights reserved.

An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of the International Committee for Future Accelerators (ICFA). The group was formed by large collider-based experiments and investigated the technical and organisational aspects of HEP data preservation. An intermediate report was released in November 2009 addressing the general issues of data preservation in HEP. This paper includes and extends the intermediate report. It provides an analysis of the research case for data preservation and a detailedmore » description of the various projects at experiment, laboratory and international levels. In addition, the paper provides a concrete proposal for an international organisation in charge of the data management and policies in high-energy physics.« less
Understanding adolescent caffeine use: connecting use patterns with expectancies, reasons, and sleep.

Little is known about adolescents' caffeine use, yet caffeinated soda, and more recently coffee and energy drinks, are part of youth culture. This study examines adolescents' caffeine use and, using cluster analysis, identifies three groups of caffeine users who differed in their reasons for use, expectancies, and sleep behaviors. In this high school student sample (N = 197), 95% of participants reported recent caffeine use-most often soda-where typical first use of the day was in the evening. Results reveal that adolescents in the mixed use and high soda use groups consumed similar amounts of soda, reporting significantly more use than the low caffeine use group. In contrast with high soda users, mixed users drank more coffee, expected more dependence symptoms and energy enhancement from caffeine, and were more likely to report getting up early, daytime sleepiness, and using caffeine to get through the day.

To examine associations of self-reported arthritis in 25 urban and rural family practice clinics with education (individual socioeconomic status) and community poverty (community socioeconomic status). A total of 7,770 patients at 25 family practice sites across North Carolina self-reported whether they had arthritis. Education was measured as less than a high school (HS) degree, a HS degree, and more than a HS degree. The US Census 2000 block group poverty rate (percentage of households in poverty in that block group) was grouped into low, middle, and high tertiles. We assumed heterogeneity by race (non-Hispanic white and African American) for the effects of these sociodemographic variables, and therefore stratified by race. Multilevel analyses were performed using a 2-level mixed logistic model to examine the independent associations and joint effects of education and poverty with self-reported arthritis as the outcome, adjusting for age, sex, and body mass index. White participants with less than a HS degree living in block groups with high poverty had 1.55 times the odds (95% confidence interval [95% CI] 1.10-2.17) of reporting arthritis compared with white participants with more than a HS degree and low poverty rates. African American participants with less than a HS degree and high poverty rates had 2.06 times the odds (95% CI 1.16-3.66) of reporting arthritis compared with African American participants with more than a HS degree and low poverty rates. In the family practice setting, both disadvantaged white and African American participants showed increased odds of self-reported arthritis, with stronger associations in African Americans.

Bullying involvement is prevalent among children and adolescents with autism spectrum disorder (ASD). This study examined the effects of theory of mind performance training (ToMPT) on reducing bullying involvement in children and adolescents with high-functioning ASD. Children and adolescents with high-functioning ASD completed ToMPT (n = 26) and social skills training (SST; n = 23) programs. Participants in both groups and their mothers rated the pretraining and posttraining bullying involvement of participants on the Chinese version of the School Bullying Experience Questionnaire. The paired t test was used to evaluate changes in bullying victimization and perpetration between the pretraining and posttraining assessments. Furthermore, the linear mixed-effect model was used to examine the difference in the training effect between the ToMPT and SST groups. The paired t test indicated that in the ToMPT group, the severities of both self-reported (p = .039) and mother-reported (p = .003) bullying victimization significantly decreased from the pretraining to posttraining assessments, whereas in the SST group, only self-reported bullying victimization significantly decreased (p = .027). The linear mixed-effect model indicated that compared with the SST program, the ToMPT program significantly reduced the severity of mother-reported bullying victimization (p = .041). The present study supports the effects of ToMPT on reducing mother-reported bullying victimization in children and adolescents with high-functioning ASD. PMID:29342210
Older adolescents' motivations for social network site use: the influence of gender, group identity, and collective self-esteem.

Barker, Valerie

2009-04-01

This study assessed motives for social network site (SNS) use, group belonging, collective self-esteem, and gender effects among older adolescents. Communication with peer group members was the most important motivation for SNS use. Participants high in positive collective self-esteem were strongly motivated to communicate with peer group via SNS. Females were more likely to report high positive collective self-esteem, greater overall use, and SNS use to communicate with peers. Females also posted higher means for group-in-self, passing time, and entertainment. Negative collective self-esteem correlated with social compensation, suggesting that those who felt negatively about their social group used SNS as an alternative to communicating with other group members. Males were more likely than females to report negative collective self-esteem and SNS use for social compensation and social identity gratifications.

Friendships differ in terms of their quality and participants may or may not agree as to their perceptions of relationship quality. Two studies ( N = 230 and 242) were conducted to identify distinct and replicable categories of friendship among young adolescents ( M = 11.6 years old) using self and partner reports of relationship quality. Same-sex friendships were identified from reciprocated friend nominations. Each friend described perceptions of negativity and social support in the relationship. Cluster analyses based on reports from both friends yielded 4 friendship types in each study: a high quality group, a low quality group, and two groups in which friends disagreed about the quality of the relationship. High quality friendships were most apt to be stable from the 6 th to the 7 th grade. Participants in high quality friendships reported the highest levels of global self-worth and perceived behavioral conduct and the lowest levels of problem behaviors. Dyads reporting discrepant perceptions of quality differed from dyads who agreed that the friendship was high quality in terms of stability and individual adjustment, underscoring the advantages of person-centered strategies that incorporate perceptions of both partners in categorizations of relationships.

This study investigated developmental trajectories for prosocial behavior for a sample followed from age 10 - 18 and examined possible adjustment outcomes associated with membership in different trajectory groups. Participants were 136 boys and 148 girls, their teachers, and their parents (19.4% African American, 2.4% Asian, 51.9% Caucasian, 19.5% Hispanic, and 5.8% other). Teachers rated children's prosocial behavior yearly in grades 4 - 12. At the end of the 12 th grade year, teachers, parents, and participants reported externalizing behaviors and participants reported internalizing symptoms, narcissism, and features of borderline personality disorder. Results suggested that prosocial behavior remained stable from middle childhood through late adolescence. Group-based mixture modeling revealed three prosocial trajectory groups: low (18.7%), medium (52.8%), and high (29.6%). Membership in the high prosocial trajectory group predicted lower levels of externalizing behavior as compared to the low prosocial trajectory group, and for girls, lower levels of internalizing symptoms. Membership in the medium prosocial trajectory group also predicted being lower on externalizing behaviors. Membership in the high prosocial trajectory group predicted lower levels of borderline personality features for girls only.

The observation of hemodynamic and metabolic impairment related to CO2 pneumoperitoneum and postoperative mesenteric ischemia reports following laparoscopic procedures have raised concern about local and systemic effects of increase intraabdominal pressure during laparoscopic procedures. The present study aims to evaluate the metabolic and acid base responses of using high pressure versus low pressure pneumoperitonium in patients undergoing laparoscopic cholecystectomy in a prospective randomized clinical trial. 20 ASA I-II patients scheduled for elective laparoscopic cholecystectomy were randomly allocated to one of two study groups; high pressure pneumoperitoneum 12-14mmHg (HPP, n=10) versus low pressure pneumoperitoneum 6-8mmHg (LPP, n=10) undergoing laparoscopic cholecystectomy. Arterial blood gases and lactate levels were determined after induction of anesthesia (before pneumoperitonium), then after 10 min, then 30 min after insufflations and at the end of surgery and 1 hour postoperatively. Nurses in recovery unit reported pain assessment starting postoperatively until 3 hours on a 10mm VAS (0-10). Statistical significant was established at P<0.05. Bicarbonate was significantly (P>0.0412) lower in high pressure group at 30 min and 60 min after insufflations. In high pressure group lactate levels increased significantly as compared to low pressure group, (at 30 minutes after the establishment of abdominal pneumatic inflation P<0.006 and remained significantly increased (P<0.001) until the end of surgery and one hour thereafter) (P<0.001). The mean postoperative pain score during second hour (VAS) at HPP group was 7.4 +/- 1.17 which is significantly (P < or = 0.006) higher than pain score in LPP group 5.0 +/- 1.886. Shoulder tip pain was reported in 3 patients in the high pressure group and only one patient in the lower pressure group. High-pressure pneumoperitonium causes statistically significant elevation in the arterial lactate level intraoperatively until one hour post operatively. It also causes higher pain score and shoulder tip pain.
Hypersexual, Sexually Compulsive, or Just Highly Sexually Active? Investigating Three Distinct Groups of Gay and Bisexual Men and Their Profiles of HIV-Related Sexual Risk

Emerging research supports the notion that sexual compulsivity (SC) and hypersexual disorder (HD) among gay and bisexual men (GBM) might be conceptualized as comprising three groups—Neither SC nor HD; SC only, and Both SC and HD—that capture distinct levels of severity across the SC/HD continuum. We examined data from 370 highly sexually active GBM to assess how the three groups compare across a range of risk factors for HIV infection. Comparisons focused on psychosexual measures—temptation for condomless anal sex (CAS), self-efficacy for avoiding CAS, sexual excitation and inhibition—as well as reports of actual sexual behavior. Nearly half (48.9 %) of this highly sexually active sample was classified as Neither SC nor HD, 30 % as SC Only, and 21.1 % as Both SC and HD. While we found no significant differences between the three groups on reported number of male partners, anal sex acts, or anal sex acts with serodiscordant partners, the Both SC and HD group reported higher numbers of CAS acts and CAS acts with serodiscordant partners and also had a higher proportion of their anal sex acts without condoms compared to the SC Only group. Our findings support the validity of a three-group classification system of SC/HD severity in differentiating psychosexual and HIV-related sexual risk behavior outcomes in a sample of GBM who report similarly high levels of sexual activity. Notwithstanding the need for sex positive HIV prevention programs, interventions that attempt to help Both SC and HD men deal with distress and address their psychosexual needs specifically may derive HIV prevention benefits.

Gulf veterans report medically unexplained symptoms more frequently than non-Gulf veterans did. We examined whether Gulf and non-Gulf veterans could be distinguished by their patterns of symptom reporting. A k-means cluster analysis was applied to 500 randomly sampled veterans from each of three United Kingdom military cohorts of veterans; those deployed to the Gulf conflict between 1990 and 1991; to the Bosnia peacekeeping mission between 1992 and 1997; and military personnel who were in active service but not deployed to the Gulf (Era). Sociodemographic, health variables and scores for ten symptom groups were calculated. The gap statistic indicated the five-group solution as one that provided a particularly informative description of the structure in the data. Cluster 1 consisted of low scores for all symptom groups. Cluster 2 had veterans with highest symptom scores for musculoskeletal symptoms and high scores for psychiatric symptoms. Cluster 3 had high scores for psychiatric symptoms and marginally elevated scores for the remaining nine groups symptom groups. Cluster 4 had elevated scores for musculoskeletal symptoms only and cluster 5 was distinguishable from the other clusters in having high scores in all symptom groups, especially psychiatric and musculoskeletal. The findings do not support the existence of a unique syndrome affecting a subgroup of Gulf veterans but emphasize the excess of non-specific self-reported ill health in this group.

The San Joaquin Valley (SJV) of California has poor air quality, high rates of asthma, and high rates of obesity. Informational campaigns aimed at increasing awareness of the health impacts of poor air quality and promoting behavior change need to be tailored to the specific target audiences. The study examined perceptions of air quality, perceived health impacts, and methods of accessing information about air quality between Latinos and other groups in the SJV. Residents of the SJV (n = 744) where surveyed via one of three methods: community organizations (256), public locations (251), and an internet panel (237). The results suggest that people perceive the air quality in their region to be generally unhealthy, particularly for sensitive groups. The air quality is more likely to be reported as being unhealthy by people with health problems and less unhealthy by Latinos and people who report regularly exercising. Latinos are more likely to report working outdoors regularly, but also more likely to report being able to reduce their exposure if the air quality is unhealthy. The results report differences in informational sources about air quality, suggesting that informational campaigns should target high risk groups using a variety of media.

The work ability of aging teachers is of special interest because of high risk of stress. The aim of the study was to follow the work ability of aging teachers and compare it with that of aging non-teacher professionals. The study included 424 teachers of age ≤ 44 years old (N = 140) and ≥ 45 years old (N = 284), with about 10% male teachers in both age groups, matched by sex and age with non-teacher professionals. Work ability was assessed by means of the Work Ability Index (WAI). Chi2 tests and regression analyses were used for studying WAI scales ratings, diagnosed by physician diseases and WAI ratings. Our data shows comparatively high work ability for both age groups of teachers but WAI of aging teachers was significantly lower in comparison to their younger colleagues as well as aging non-teacher professionals. About 80% of aging groups reported diseases diagnosed by physicians. Cardiovascular, musculoskeletal and respiratory diseases were the most frequently reported by aging teachers, while teachers ≤ 44 years old reported respiratory, cardiovascular, neurological and sensory diseases. With aging significantly higher rates of arterial hypertension, diabetes, injury to hearing and mental disorders were reported by teachers as compared to aging non-teacher professionals. The rates of reported repeated infections of respiratory tracts were high in both age groups of teachers, especially in the group of aging teachers. The estimated work ability impairment due to the disease showed the significant effect of aging for teachers as well as the significant difference when comparing aging teachers and non-teacher professionals. Our data shows high work ability for both age groups of teachers but significantly lower for aging teachers accompanied with higher rates of psychosomatic diseases, including hearing impairment and respiratory diseases. Preservation of teacher health could contribute to maintenance of their work ability and retention in the labor market.

The objective of this review was to investigate whether Chinese population groups that do not belong to classical high risk groups show an increasing trend of engaging in high-risk sexual behaviors. We systematically searched the English and Chinese literature on sexual risk behaviors published between January 1980 and March 2012 in PubMed and the China National Knowledge Infrastructure (CNKI). We included observational studies that focused on population groups other than commercial sex workers (CSWs) and their clients, and men who have sex with men (MSM) and quantitatively reported one of the following indicators of recent high-risk sexual behavior: premarital sex, commercial sex, multiple sex partners, condom use or sexually transmitted infections (STIs). We used generalized linear mixed model to examine the time trend in engaging in high-risk sexual behaviors. We included 174 observational studies involving 932,931 participants: 55 studies reported on floating populations, 73 on college students and 46 on other groups (i.e. out-of-school youth, rural residents, and subjects from gynecological or obstetric clinics and premarital check-up centers). From the generalized linear mixed model, no significant trends in engaging in high-risk sexual behaviors were identified in the three population groups. Sexual risk behaviors among certain general population groups have not increased substantially. These groups are therefore unlikely to incite a STI/HIV epidemic among the general Chinese population. Because the studied population groups are not necessarily representative of the general population, the outcomes found may not reflect those of the general population.

Effort-recovery theory (Meijman and Mulder in Handbook of work and organizational psychology, Psychology Press/Erlbaum, Hove, pp 5-33, 1998) proposes that effort expenditure may have adverse consequences for health in the absence of sufficient recovery opportunities. Thus, insight in the relationships between effort and recovery is imperative to understand work-related health. This study therefore focused on the relation between work-related effort and recovery (1) during workdays, (2) in-between workdays and (3) in the weekend. For these three time periods, we compared a group of employees reporting relatively low levels of work-related effort ("low-effort group") and a group of employees reporting relatively high levels of work-related effort ("high-effort group") with respect to (1) activity patterns, (2) the experience of these activity patterns, and (3) health and well-being indicators. Data were collected among university staff members. Participants (N(high-effort group) = 24 and N(low-effort group) = 27) completed a general questionnaire and took part in a 7-day daily diary study covering five weekdays and the following weekend. Differences between the two effort-groups were examined by means of analysis of variance. Compared to the low-effort group, the high-effort group (1) engaged less often in active leisure activities during the week and worked more overtime in the weekend, (2) considered both work and home activities as more effortful, but not as less pleasurable, and (3) reported higher levels of sleep complaints (weekdays only) and fatigue, more preoccupation with work (weekdays only) and lower motivation to start the next workweek during the weekend. Work-related effort is associated with various aspects of work time and (potential) recovery time in-between workdays and in the weekend. High levels of work-related effort are associated with activity patterns that are less beneficial in terms of recovery, with higher effort expenditure during and after work time, and with diminished health and well-being.

Background Physical activity declines as children approach puberty. Research has focussed on psychosocial, environmental, and demographic determinants. This paper explores how family and socioeconomic factors are related to children's physical activity. Methods Seventeen focus groups were conducted with 113, 10–11 year old children from 11 primary schools in Bristol, UK. Focus groups examined: 1) the way parents encourage their children to be physically active; 2) the extent to which physical activity is engaged in as a family; and 3) the types of non-family based physical activities Year 6 children commonly participate in. Results Participants from all socioeconomic (SES) groups reported that parents encouraged them to be physically active. However approaches differed. Children from middle/high SES schools were assisted through actions such as logistical and financial support, co-participation and modelling. Parents of children from low SES schools mainly restricted their input to verbal encouragement and demands. Participation in family-based activities was reported to be higher in children from middle/high SES schools than children from low SES schools. All SES groups reported time to be a limiting factor in family-based activity participation. Cost was reported as a significant barrier by children from low SES schools. Children from middle/high SES schools reported engaging in more sports clubs and organised activities than children from low SES schools, who reported participating in more unstructured activities or 'free play' with friends. Conclusion The family is important for encouraging children to be physically active, but families from different socioeconomic backgrounds support their children in different ways. This research suggests that the design of physical activity interventions, which might include working with families, requires tailoring to groups from different socio-economic backgrounds.

2016-01-01

To assess the effects of two sports-related concussions on neuropsychological functioning and symptom reporting, the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) was administered to 483 high school athletes. Three groups of athletes were determined based on the number of previous concussions: no concussion (n = 409), 1 concussion (n = 58), and 2 concussions (n = 16). The results showed that the three groups did not differ in terms of their ImPACT composite scores (Verbal Memory, Visual Memory, Reaction Time, and Processing Speed) and the Total Symptom Score. As there are only a few studies that have reported the sequelae of 2 concussions in high school athletes, it is premature to declare that a repeated concussion does not have persistent neurocognitive effects on high school athletes.

The objective of this study was to develop a high-fidelity prototype for delivering multi-gene sequencing panel (GS) reports to clinicians that simulates the user experience of a final application. The delivery and use of GS reports can occur within complex and high-paced healthcare environments. We employ a user-centered software design approach in a focus group setting in order to facilitate gathering rich contextual information from a diverse group of stakeholders potentially impacted by the delivery of GS reports relevant to two precision medicine programs at the University of Maryland Medical Center. Responses from focus group sessions were transcribed, coded and analyzed by two team members. Notification mechanisms and information resources preferred by participants from our first phase of focus groups were incorporated into scenarios and the design of a software prototype for delivering GS reports. The goal of our second phase of focus group, to gain input on the prototype software design, was accomplished through conducting task walkthroughs with GS reporting scenarios. Preferences for notification, content and consultation from genetics specialists appeared to depend upon familiarity with scenarios for ordering and delivering GS reports. Despite familiarity with some aspects of the scenarios we proposed, many of our participants agreed that they would likely seek consultation from a genetics specialist after viewing the test reports. In addition, participants offered design and content recommendations. Findings illustrated a need to support customized notification approaches, user-specific information, and access to genetics specialists with GS reports. These design principles can be incorporated into software applications that deliver GS reports. Our user-centered approach to conduct this assessment and the specific input we received from clinicians may also be relevant to others working on similar projects. Copyright © 2016 Elsevier Inc.

2017-02-28

The aim of this study was to examine the effects of head impact frequency on the neuropsychological test results of football players who participate in different positions on the team. Based on the biomechanical measures of head impact frequency reported in high school football, a High Contact group (n = 480) consisting of offensive and defensive linemen was compared with a Low Contact group (n = 640) comprised of receivers and defensive backs. The results revealed that the High Contact group obtained poorer performances on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) on three Composite scores (Verbal Memory, Visual Motor Speed, Impulse Control) and the Total Symptom score compared to the Low Contact group. The present study is the first, to date, to report differences in the neuropsychological test performances of athletes who participate in high and low contact football positions. The findings raise tentative concerns that youth football players exposed to repetitive head trauma, including subconcussive impacts, may be at risk for lowered neuropsychological functioning and increased symptoms.

The objective of our study was to assess whether high-fidelity simulation-based training is more effective than traditional didactic lecture to train radiology residents in the management of contrast reactions. This was a prospective study of 44 radiology residents randomized into a simulation group versus a lecture group. All residents attended a contrast reaction didactic lecture. Four months later, baseline knowledge was assessed with a written test, which we refer to as the "pretest." After the pretest, the 21 residents in the lecture group attended a repeat didactic lecture and the 23 residents in the simulation group underwent high-fidelity simulation-based training with five contrast reaction scenarios. Next, all residents took a second written test, which we refer to as the "posttest." Two months after the posttest, both groups took a third written test, which we refer to as the "delayed posttest," and underwent performance testing with a high-fidelity severe contrast reaction scenario graded on predefined critical actions. There was no statistically significant difference between the simulation and lecture group pretest, immediate posttest, or delayed posttest scores. The simulation group performed better than the lecture group on the severe contrast reaction simulation scenario (p = 0.001). The simulation group reported improved comfort in identifying and managing contrast reactions and administering medications after the simulation training (p ≤ 0.04) and was more comfortable than the control group (p = 0.03), which reported no change in comfort level after the repeat didactic lecture. When compared with didactic lecture, high-fidelity simulation-based training of contrast reaction management shows equal results on written test scores but improved performance during a high-fidelity severe contrast reaction simulation scenario.

Topical tretinoin is a medication commonly used for acne that has potential application in the long-term treatment of photodamaged skin. However, there are few published data regarding the tolerability of high-dose tretinoin with long-term use. To assess the long-term tolerability of tretinoin 0.1% cream. A randomized, multicentre, double-blind, controlled trial for chemoprevention of keratinocyte carcinomas (i.e. basal cell or squamous cell carcinomas) using topical tretinoin cream to the face and ears was conducted. All participants were veterans and had a history of two or more keratinocyte carcinomas over the previous 5 years. Participants were examined (by a study dermatologist) and interviewed every 6 months (for up to 5.5 years to May 2004). Treatment comprised tretinoin 0.1% cream or vehicle control cream once daily, then twice daily as tolerated. Participants were instructed to step down application frequency to once daily or less if twice daily was not tolerated. The main outcome measures were reported side-effects, frequency of cream application and attendance at study visits. Appropriate data were available for four of the six clinical sites of this trial. Data from 736 randomized participants (mean age 71 years; 97% men) from four clinical sites were analysed. The tretinoin group more commonly reported one or more side-effects at the 6-month follow-up than the control group (61% vs. 42%, P < 0.0001). Side-effects decreased over time in both groups, but to a greater extent in the tretinoin group, and the difference became nonsignificant at 30 months. Burning was the most common side-effect (39% tretinoin vs. 17% control, P < 0.0001). There was no difference in severity of side-effects among those affected. Of the participants who reported burning in either group, most reported mild burning; only 11% of those with burning in the tretinoin group reported it as severe (mild 62% tretinoin vs. 70% placebo; severe 11% vs. 5%; P = 0.4). Itching (24% vs. 16%, P = 0.01) and other local cutaneous reactions (12% vs. 6%, P = 0.01) were also more commonly reported by the tretinoin group at 6 months. There was no difference in numbness (2% vs. 2%, P = 0.9). Participants in the tretinoin group were less likely to apply cream twice daily at 6 months (29% vs. 43%, P = 0.0002). This difference persisted over the entire duration of follow-up. There was little difference between groups in attendance at study visits or completion of telephone interviews (92% vs. 95%, P = 0.06). No unexpected adverse events were reported. Overall, the tolerability level of topical tretinoin was high in this study population, with almost 40% of the tretinoin group reporting no side-effects, and the majority (67%) tolerating at least once-daily dosing at 6-month follow-up. High-dose topical tretinoin is feasible for long-term use in this population.
Disentangling Emotion Processes in Borderline Personality Disorder: Physiological and Self-reported Assessment of Biological Vulnerability, Baseline Intensity, and Reactivity to Emotionally-Evocative Stimuli

This study investigated Linehan’s (1993) theory that individuals meeting criteria for borderline personality disorder (BPD) have high biological vulnerability to emotion dysregulation, including high baseline emotional intensity and high reactivity to emotionally-evocative stimuli. Twenty individuals with BPD, 20 age-matched individuals with generalized social anxiety disorder (SAD), and 20 age-matched normal controls (NC) participated in two separate emotion induction conditions, a standardized condition and a personally-relevant condition. Respiratory sinus arrhythmia (RSA), skin conductance response (SCR), and self-report measures were collected throughout the experiment. BPD participants displayed heightened biological vulnerability compared with NC as indicated by reduced basal RSA. BPD participants also exhibited high baseline emotional intensity, characterized by heightened SCR and heightened self-reported negative emotions at baseline. However, the BPD group did not display heightened reactivity as their physiological and self-reported changes from baseline to the emotion inductions tasks were not greater than the other two groups.

Personal and family perfectionism of Taiwanese college students: relationships with depression, self-esteem, achievement motivation, and academic grades.

Wang, Kenneth T

2012-01-01

An increasing number of perfectionism studies have been conducted across different countries outside of the Western framework. Using an international egalitarian approach that adopts indigenous frameworks and concepts from the cultural context of the population studied is imperative. This study examines different groups of perfectionists with a sample of 348 Taiwanese college students, emphasizing the collectivistic culture. In particular, this is a follow-up study to further explore characteristics of a group with low standards/high discrepancy--a feeling that they are not good enough despite having low standards--found in a previous study with Taiwanese students. More specifically, this study investigates whether the source of the high discrepancy scores among this group is related to having higher perfectionistic standards from their family. Perfectionism was examined not only from a personal/individualistic perspective, but also from a familistic dimension to reflect Taiwanese collectivistic cultural values. Results partially supported the hypotheses--this group reported having higher family discrepancy, but not family standards, than nonperfectionists. However, this group of participants reported lower academic grades, which implies the possibility of their discrepancy being associated with poorer performance. Four cluster groups--adaptive perfectionists, maladaptive perfectionists, nonperfectionists, and those with low standards/high discrepancy--were compared on their levels of depression, self-esteem, achievement motivation, and academic grades. Maladaptive perfectionists reported the highest depression level, while adaptive perfectionists reported the highest self-esteem. Results also show that aspects of personal perfectionism and family perfectionism related to self-esteem differently among this sample. Findings and implications are discussed with consideration of the collectivistic cultural context in Taiwan.

Objectives To examine differences in health-related behaviours such as screening or testing for cancer, use of hormone replacement therapy (HRT) and use of other medications in different diet groups. Design We studied 31 260 participants across four diet groups (18 155 meat eaters, 5012 fish eaters, 7179 vegetarians, 914 vegans) in the UK EPIC-Oxford cohort. Information was collected in 5-year (around 2000–2003) or 10-year (around 2007) follow-up questionnaires regarding participation in breast screening, cervical screening, prostate-specific antigen (PSA) testing, use of HRT and use of medications for the past 4 weeks. Using Poisson regression, we estimated the prevalence ratios (PR) for each behaviour across people of different diet groups, using meat eaters as the reference group. Results Compared with meat eaters, vegetarian (PR: 0.94, 95% CI 0.89 to 0.98) and vegan (PR: 0.82, 95% CI 0.71 to 0.95) women reported lower participation in breast screening, and vegetarian men were less likely to report PSA testing (PR: 0.82, 95% CI 0.71 to 0.96). No differences were observed among women for cervical screening. In women, all non-meat-eating groups reported lower use of HRT compared with meat eaters (P heterogeneity <0.0001). Lower reported use of any medication was observed for participants in all non-meat-eating groups with no (P<0.0001) or one (P=0.0002) self-reported illness. No heterogeneity was observed across the diet groups for the reported use of specific medication for high blood pressure, high blood cholesterol, asthma, diabetes and thyroid disease. Conclusions Differences in self-reported breast screening, PSA testing, HRT use and overall medication use were observed across the diet groups. Whether such differences contribute to differential long-term disease risks requires further study. PMID:29284719
Trajectories of Marital Conflict Across the Life Course: Predictors and Interactions With Marital Happiness Trajectories

Kamp Dush, Claire M.; Taylor, Miles G.

2011-01-01

Using typologies outlined by Gottman and Fitzpatrick as well as institutional and companionate models of marriage, the authors conducted a latent class analysis of marital conflict trajectories using 20 years of data from the Marital Instability Over the Life Course study. Respondents were in one of three groups: high, medium (around the mean), or low conflict. Several factors predicted conflict trajectory group membership; respondents who believed in lifelong marriage and shared decisions equally with their spouse were more likely to report low and less likely to report high conflict. The conflict trajectories were intersected with marital happiness trajectories to examine predictors of high and low quality marriages. A stronger belief in lifelong marriage, shared decision making, and husbands sharing a greater proportion of housework were associated with an increased likelihood of membership in a high happiness, low conflict marriage, and a decreased likelihood of a low marital happiness group.

Some healthy athletes report high levels of baseline concussion symptoms, which may be attributable to several factors (eg, illness, personality, somaticizing). However, the role of baseline symptoms in outcomes after sport-related concussion (SRC) has not been empirically examined. To determine if athletes with high symptom scores at baseline performed worse than athletes without baseline symptoms on neurocognitive testing after SRC. Cohort study. High school and collegiate athletic programs. A total of 670 high school and collegiate athletes participated in the study. Participants were divided into groups with either no baseline symptoms (Postconcussion Symptom Scale [PCSS] score = 0, n = 247) or a high level of baseline symptoms (PCSS score > 18 [top 10% of sample], n = 68). Participants were evaluated at baseline and 2 to 7 days after SRC with the Immediate Post-concussion Assessment and Cognitive Test and PCSS. Outcome measures were Immediate Post-concussion Assessment and Cognitive Test composite scores (verbal memory, visual memory, visual motor processing speed, and reaction time) and total symptom score on the PCSS. The groups were compared using repeated-measures analyses of variance with Bonferroni correction to assess interactions between group and time for symptoms and neurocognitive impairment. The no-symptoms group represented 38% of the original sample, whereas the high-symptoms group represented 11% of the sample. The high-symptoms group experienced a larger decline from preinjury to postinjury than the no-symptoms group in verbal (P = .03) and visual memory (P = .05). However, total concussion-symptom scores increased from preinjury to postinjury for the no-symptoms group (P = .001) but remained stable for the high-symptoms group. Reported baseline symptoms may help identify athletes at risk for worse outcomes after SRC. Clinicians should examine baseline symptom levels to better identify patients for earlier referral and treatment for their injury. Additional investigation of baseline symptoms is warranted to help delineate the type and severity of premorbid symptoms.
Multinomial logistic regression analysis for differentiating 3 treatment outcome trajectory groups for headache-associated disability.

Lewis, Kristin Nicole; Heckman, Bernadette Davantes; Himawan, Lina

2011-08-01

Growth mixture modeling (GMM) identified latent groups based on treatment outcome trajectories of headache disability measures in patients in headache subspecialty treatment clinics. Using a longitudinal design, 219 patients in headache subspecialty clinics in 4 large cities throughout Ohio provided data on their headache disability at pretreatment and 3 follow-up assessments. GMM identified 3 treatment outcome trajectory groups: (1) patients who initiated treatment with elevated disability levels and who reported statistically significant reductions in headache disability (high-disability improvers; 11%); (2) patients who initiated treatment with elevated disability but who reported no reductions in disability (high-disability nonimprovers; 34%); and (3) patients who initiated treatment with moderate disability and who reported statistically significant reductions in headache disability (moderate-disability improvers; 55%). Based on the final multinomial logistic regression model, a dichotomized treatment appointment attendance variable was a statistically significant predictor for differentiating high-disability improvers from high-disability nonimprovers. Three-fourths of patients who initiated treatment with elevated disability levels did not report reductions in disability after 5 months of treatment with new preventive pharmacotherapies. Preventive headache agents may be most efficacious for patients with moderate levels of disability and for patients with high disability levels who attend all treatment appointments.

Flynn, Elinor; Ehrenreich, Samuel E.; Beron, Kurt J.; Underwood, Marion K.

2015-01-01

This study investigated developmental trajectories for prosocial behavior for a sample followed from age 10 – 18 and examined possible adjustment outcomes associated with membership in different trajectory groups. Participants were 136 boys and 148 girls, their teachers, and their parents (19.4% African American, 2.4% Asian, 51.9% Caucasian, 19.5% Hispanic, and 5.8% other). Teachers rated children’s prosocial behavior yearly in grades 4 – 12. At the end of the 12th grade year, teachers, parents, and participants reported externalizing behaviors and participants reported internalizing symptoms, narcissism, and features of borderline personality disorder. Results suggested that prosocial behavior remained stable from middle childhood through late adolescence. Group-based mixture modeling revealed three prosocial trajectory groups: low (18.7%), medium (52.8%), and high (29.6%). Membership in the high prosocial trajectory group predicted lower levels of externalizing behavior as compared to the low prosocial trajectory group, and for girls, lower levels of internalizing symptoms. Membership in the medium prosocial trajectory group also predicted being lower on externalizing behaviors. Membership in the high prosocial trajectory group predicted lower levels of borderline personality features for girls only. PMID:26236108

The objective of this study is to examine depressive symptom trajectories during adolescence as predictors of physical activity (PA) in young adulthood. Adolescents residing in Montreal, Canada (n=860) reported their depressive symptoms every 3-4 months during high school in 20 data collections. Three years later, participants reported engaging in moderate and vigorous intensity PA and team sports participation. Trajectories of depressive symptoms were estimated using latent growth modeling and examined as predictors of PA outcomes. Three depression symptom trajectory groups were identified during adolescence: low and declining depressive symptom scores (group 1; 37.8%); moderate and stable depressive symptom scores (group 2; 41.6%); and high increasing depressive symptom scores (group 3; 20.6%). In multivariable analyses, group 2 and group 3 participated in less moderate-intensity PA and were less likely to participate in team sports compared to group 1. The importance of examining intensity and type of PA as outcomes of depressive symptoms is highlighted. Targeted approaches are needed to encourage adolescents with moderate to high depression symptoms to engage in PA and team sports to improve their health and well-being.

Background Population stratification is the main source of spurious results and poor reproducibility in genetic association findings. Population heterogeneity can be controlled for by grouping individuals in ethnic clusters; however, in admixed populations, there is evidence that such proxies do not provide efficient stratification control. The aim of this study was to evaluate the relation of self-reported with genetic ancestry and the statistical risk of grouping an admixed sample based on self-reported ancestry. Methods A questionnaire that included an item on self-reported ancestry was completed by 189 female volunteers from an admixed Brazilian population. Individual genetic ancestry was then determined by genotyping ancestry informative markers. Results Self-reported ancestry was classified as white, intermediate, and black. The mean difference among self-reported groups was significant for European and African, but not Amerindian, genetic ancestry. Pairwise fixation index analysis revealed a significant difference among groups. However, the increase in the chance of type 1 error was estimated to be 14%. Conclusions Self-reporting of ancestry was not an appropriate methodology to cluster groups in a Brazilian population, due to high variance at the individual level. Ancestry informative markers are more useful for quantitative measurement of biological ancestry. PMID:21498954

Group sex among gay men has been associated with other HIV risk behaviours. Gay men who engage in group sex may be at increased risk of infection with HIV and other sexually transmitted infections (STI). The Three or More Study (TOMS) of group sex among gay men utilised an anonymous, self-completed survey about participants' most recent occasion of group sex with other men and in-depth interviews with a small number of these survey participants. The 436 men who reported having engaged in group sex within the previous month were included in these analyses. Among 436 men who engaged in group sex within the previous month, 32.5% reported unprotected anal intercourse (UAI) with non-regular, mostly HIV non-seroconcordant partners at this recent group sex encounter (GSE) and the majority reported other sex practices that are risk factors for STI other than HIV. Over one-third reported having been tested for HIV or other STI since their last GSE; those who had engaged in UAI at the GSE were more likely to have been tested (p = 0.008). Men who had a doctor with whom they were able to discuss their group sex activities had received a broader range of STI tests (p = 0.003). Sex practices that risk the transmission of STI were common within this high-risk sample, whereas awareness of risk and the need for testing was high but not universal. Frank discussion with doctors of patients' group sex behaviour also enhanced decisions about adequate testing. Gay men in group sex networks are an appropriate priority for sexual health screening.

Excessive pain during medical procedures performed in unanesthetized patients is frequently reported, but can be reduced with virtual reality (VR) distraction. Increasing the person's illusion of going into the virtual world may increase how effectively VR distracts pain. Healthy volunteers aged 18-20 years participated in a double-blind between-groups design. Each subject received a brief baseline thermal pain stimulus, and the same stimulus again minutes later with either a Low Tech or a High Tech VR distraction. Each subject provided subjective 0-10 ratings of cognitive, sensory and affective components of pain, and rated their illusion of going inside the virtual world. Subjects in the High Tech VR group reported a stronger illusion of going into the virtual world (VR presence) than subjects in the Low Tech VR group, (4.2 vs. 2.5, respectively, P = 0.009) and more pain reduction (reduction of worst pain is 3.1 for High Tech VR vs. 0.7 for Low Tech VR, P < 0.001). Across groups, the amount of pain reduction was positively and significantly correlated with VR presence levels reported by subjects ( r = 0.48 for 'worst pain', P < 0.005).

To obtain joint hypermobility classes in children from the general population and to study their characteristics in relation to anxiety measures. A total of 336 nine-year-old children from the general population were clinically assessed through 9 items of hypermobility, and their parents reported about the severity of anxiety symptoms. Latent class analysis was estimated to group the children according to the presence of hypermobility symptoms, and the obtained classes were related to anxiety. A 2-class solution, labeled as high hypermobility and low hypermobility, best fitted the data. Children in the high hypermobility group scored higher in separation anxiety, social phobia, physical injury fears, and total anxiety than did those in the low group. When applying the threshold reference scores to the total anxiety score, 7.4% of children in the high hypermobility group versus 6% in the low group were reported to experience clinical elevations on total anxiety. High symptoms of hypermobility are associated with higher scores in anxiety symptoms in children from the general population. Children with frequent symptoms of hypermobility may benefit from screening for anxiety symptoms because a subset of them are experiencing clinical elevations and may need comprehensive physical and psychological treatment.
Aggression after traumatic brain injury: analysing socially desirable responses and the nature of aggressive traits.

To compare patients with traumatic brain injury (TBI) with controls on sub-types of aggression and explore the role of social desirability. Quasi-experimental, matched-participants design. Sixty-nine participants were included in the study. The sample comprised a TBI group (n = 24), a spinal cord injury (SCI) group (n = 21) and an uninjured (UI) group of matched healthy volunteers (n = 24). Participants were given self-report measures of aggression, social desirability and impulsivity. Sixty-one independent 'other-raters' were nominated, who rated participant pre-morbid and post-morbid aggression. Using standardized norms, 25-39% of participants with TBI were classified as high average-very high on anger and 35-38% as high average-very high on verbal aggression. Other-raters rated participants with TBI as significantly higher on verbal aggression than SCI and UI participants. There were no differences between the groups on physical aggression. The TBI group also had higher levels of impulsivity than SCI and UI groups. Social desirability was a highly significant predictor of self-reported aggression for the entire sample. Impulsive verbal aggression and anger are the principal aggressive traits after brain injury. Physical aggression may present in extreme cases after TBI, but appears less prominent overall in this population. Social desirability, previously overlooked in research examining TBI aggression, emerged as an influential variable that should be considered in future TBI research.
Effects of trauma and religiosity on self-esteem.

Self-esteem is often lower among persons who have experienced trauma, but religiosity may ameliorate these psychological effects. The purpose of this paper was to examine the relationships among religiosity, self-esteem, and childhood exposure to trauma, utilizing data from the National Comorbidity Survey, a large (N = 8,098) nationally representative population survey in the 48 contiguous states of the USA that assessed religious practices, self-esteem, and exposure to trauma. Exposure to trauma in childhood was assessed through self-report of presence or absence of childhood physical abuse, sexual abuse, or neglect. Religiosity was assessed as the sum of responses to 4 self-report items (religious service attendance, use of religion for comfort and guidance, and importance of religion). Self-esteem was assessed on 9 self-report items adapted from the Rosenberg Self-Esteem Scale. Analysis of variance compared scores for persons who reported exposure to childhood abuse and differed in the value they placed on various religious practices on self-esteem. Persons who reported physical abuse, sexual abuse, or neglect in childhood had significantly lower mean self-esteem than those who did not report these events. There was also a main effect for religiosity in a comparison of persons who reported childhood sexual abuse with those who reported none. The High Religiosity group had higher mean self-esteem than the Medium and Low Religiosity groups. There was a significant interaction as those who reported childhood sexual abuse had lower mean self-esteem than peers who reported none in the Low and Medium Religiosity groups. Mean self-esteem for those who reported childhood sexual abuse was comparable to that of those who reported none in the High Religiosity group.
Using self-report and adverse event measures to track health's impact on productivity in known groups.

Allen, Harris M; Bunn, William B

2003-09-01

The use of survey data to measure and monitor health and productivity differences between groups is an issue of increasing importance. This article examines the capacity of productivity self-reports (derived from surveys) and adverse event measures (derived from administrative sources) to differentiate groups with a priori known characteristics. A replication strategy is used to test the contributions that productivity self-reports make, alone as well as above and beyond measures of adverse events, to the discrimination of 5 pairs of groups classified by clinical, job type, and demographic criteria. These tests are conducted on representative samples of the active, largely blue-collar employee population at International Truck and Engine Corporation. The results show that both productivity self-reports and adverse event measures differentiate and track known groups. Even in the presence of highly significant effects from adverse event measures, self-reports improve the assessment of productivity. We conclude that: 1) although the joint use of self-reports and adverse event measures is the better approach, practitioners can use self-reports with the expectation that this method will track group differences in health and productivity when adverse event measures are not available; and 2) survey self-reports make unique and independent contributions when adverse events measures are used.

Developmental trajectories in delinquency through adolescence were studied along with family and peer relationship problems. Drawing from eight waves of data over seven years, we conducted trajectory analyses with a sample of 746 students (402 girls; 344 boys). Analyzing girls and boys together, a five-class model emerged: 60% of the adolescents rarely reported delinquency; 27.7% reported low initial levels with moderate levels of delinquency over time; 6% in the late onset group reported initially low and rising levels of delinquency; 5% in the early onset group reported moderate initial levels which increased and then decreased in later adolescence. A small group of only boys (1.3%) labeled chronic reported high initial levels of delinquency that increased over time. Group comparisons revealed problems in internalizing, parent and peer relationship problems. The findings provide direction for early identification and interventions to curtail the development of delinquency.

Ecstasy (MDMA) and high prevalence psychiatric symptomatology: somatic anxiety symptoms are associated with polydrug, not ecstasy, use.

PubMed

Bedi, G; Van Dam, N T; Redman, J

2010-02-01

Although previous studies have examined anxiety and depression in ecstasy (+/-3,4-methylenedioxymethamphetamine; MDMA) users, it remains unclear whether symptoms are associated specifically with ecstasy or with polydrug use in general. We compared mean symptomatology and clinically significant symptoms in 45 ecstasy polydrug, 48 cannabis polydrug and 40 legal drug users, who completed standardised self-report anxiety and depression symptom measures. We further examined whether group differences were secondary to increased somatic symptom reporting, which may reflect acute/subacute drug effects. Anxiety and depression scores were higher in polydrug than legal drug users, with no difference between ecstasy and cannabis groups. There was no difference in numbers meeting criteria for clinically significant depression or 'moderate' or 'severe' anxiety, but the polydrug group contained more individuals reporting at least 'mild' anxiety symptoms than the legal drug control. Multivariate analyses indicated that anxiety alone was sufficient to discriminate groups. Polydrug users reported more somatic anxiety symptoms than legal drug users, but endorsed equivalent numbers of non-somatic symptoms. High prevalence psychiatric symptomatology in ecstasy polydrug users may be associated with polydrug rather than ecstasy use. Higher ratings in polydrug users appear to be secondary to increased somatic symptom reporting, suggesting possible impacts of drug effects on symptom endorsement.

We investigated the sleep problems and sleep habits of adolescents at three public primary schools and two high schools. Our study included 428 Turkish school children (244 girls and 184 boys). We used a questionnaire to determine the time they went to sleep at night; waking time in the morning; incidence of nightmares, snoring, daytime sleepiness, and intrafamilial physical trauma; concentration difficulty in class; and school success. The students were divided into age-related groups (group 1 = 11 to 13 years of age; group 2 = 14 to 15 years; group 3 = 16 to 18 years). The time they went to sleep was mostly between 10 and 11 p.m. in groups 1 and 2, and 11 to 12 p.m. in group 3. Difficulty in falling asleep was reported by 16.8 to 19.6% of the students in the three groups. Difficulty in waking up in the morning was reported by 12.7% of group 1, 16.0% of group 2, and 16.8% of group 3. Snoring was present in 12.1% of females and 22.0% of males. The occurrence of one nightmare in the preceding 3 months was reported by 11.3% of the students; 17.9% of the students reported having nightmares several times. Daytime sleepiness was present in 65.1%, and concentration difficulty was present in 56.8% of the students. We conclude that difficulty in falling asleep, snoring, and daytime sleepiness may be seen in adolescents who are in both primary and high schools. Watching inappropriate programs and movies on television and intrafamilial physical trauma may cause nightmares and sleeping problems in these adolescents. Students and families should be educated about the importance of sleep in academic performance. Countries' public health policies should address sleep problems and related educational activities.

1991-01-01

Rats were fed an irradiated high-moisture diet (KSC-25) with or without access to a water bottle. Physiologic values were compared between these two groups and a group of rats fed a purified diet. Hematologic and serum biochemical values, urine specific gravity, and intestinal enzyme activities were determined from samples collected from the three groups of rats. Sprague Dawley rats (n=32) fed the irradiated high-moisture diet with or without a water bottle were the test animals. Rats (n=16) fed an irradiated purified diet and water provided via a water bottle were the control group. The purified diet formulation, modified AIN-76A, is a commonly used purified diet for laboratory rodents. All rats remained alert and healthy throughout the study. A comparison of the physiologic values of rats in this study with reported normal values indicated that all of the rats in the study were in good health. Significant differences (P less than 0.05) of the physiologic values from each rat group are reported.
Friendship group identification, multidimensional self-concept, and experience of developmental tasks in adolescence.

Tarrant, Mark; MacKenzie, Liam; Hewitt, Lisa A

2006-08-01

This study applied a social identity perspective to the study of adolescent self-concept and social development. British adolescents aged 14-15 years (N=114) completed a questionnaire which asked them to: (i) rate their degree of identification with a school-based friendship group; (ii) complete a measure of multi-dimensional self-concept; and (iii) report their experiences of a variety of personal, relational and socio-institutional (e.g., achieving economic independence) developmental tasks. Compared to low identifiers, participants who were highly identified with a friendship group reported highest levels of self-esteem; and these differences were most marked in non-academic domains of self. High identifiers also displayed higher levels of general self-esteem and reported more positive experiences of personal and relational developmental tasks. The discussion focuses on the potential benefits to understanding of social developmental processes that can be derived from a consideration of adolescents' subjective appraisals of their peer relations.

Evidence on the analgesic effectiveness of nitrous oxide for labor pain is limited. Even fewer studies have looked at patient satisfaction. Although nitrous oxide appears less effective than neuraxial analgesia, it is unclear whether labor analgesic effectiveness is the most important factor in patient satisfaction. We sought to compare the relationship between analgesic effectiveness and patient satisfaction with analgesia in women who delivered vaginally using nitrous oxide, neuraxial analgesia (epidural or combined spinal-epidural [CSE]), or both (neuraxial after a trial of nitrous oxide). A standardized survey was recorded on the first postpartum day for all women who received anesthetic care for labor and delivery. Data were queried for women who delivered vaginally with nitrous oxide and/or neuraxial labor analgesia over a 34-month period in 2011 to 2014. Parturients with complete data for analgesia quality and patient satisfaction were included. Analgesia and satisfaction scores were grouped into 8 to 10 high, 5 to 7 intermediate, and 0 to 4 low. These scores were compared with the use of ordinal logistic regression across 3 groups: nitrous oxide alone, epidural or CSE alone, or nitrous oxide followed by neuraxial (epidural or CSE) analgesia. A total of 6507 women received anesthesia care and delivered vaginally. Complete data were available for 6242 (96%) women; 5261 (81%) chose neuraxial analgesia and 1246 (19%) chose nitrous oxide. Of the latter, 753 (60%) went on to deliver with nitrous oxide alone, and 493 (40%) switched to neuraxial analgesia. Most parturients who received neuraxial analgesia (>90%) reported high analgesic effectiveness. Those who used nitrous oxide alone experienced variable analgesic effectiveness, with only one-half reporting high effectiveness. Among all women who reported poor analgesia effectiveness (0-4; n = 257), those who received nitrous oxide alone were more likely to report high satisfaction (8-10) than women who received epidural analgesia alone (OR 2.5; 95% CI 1.4-4.5; P = .002). Women who reported moderate analgesia (5-7) and received nitrous oxide only were more likely to report high satisfaction compared with the other groups. Among women who reported a high level of analgesic effectiveness, satisfaction with anesthesia was high and not different among groups. Patients who received nitrous oxide alone were as likely to express satisfaction with anesthesia care as those who received neuraxial analgesia, even though they were less likely to report excellent analgesia. Although pain relief contributes to the satisfaction with labor analgesia care, our results suggest that analgesia is not the only contributor to maternal satisfaction.

2012-01-01

This study explored the possibility that specific, theoretically consistent profiles of reactivity could be identified in a sample of cocaine-exposed infants and whether these profiles were associated with a range of infant and/or maternal characteristics. Cluster analysis was used to identify distinct groups of infants based on physiological, behavioral and maternal reported measures of reactivity. Five replicable clusters were identified which corresponded to 1) Dysregulated/High Maternal Report Reactors, 2) Low Behavioral Reactors, 3) High Reactors, 4) Optimal Reactors and 5) Dysregulated/Low Maternal Report Reactors. These clusters were associated with differences in prenatal cocaine exposure status, birthweight, maternal depressive symptoms, and maternal negative affect during mother-infant interactions. These results support the presence of distinct reactivity profiles among high risk infants recruited on the basis of prenatal cocaine exposure and demographically similar control group infants not exposed to cocaine.

Health effects of occupational exposure to lead were investigated among 92 exposed workers in lead-acid battery factory and 40 nonexposed workers serving as a control group from an oil mill in Khartoum North industrial area. The two groups were closely similar in age, stature, body weight, and socioeconomic conditions. A highly significant increase (P<.01) was recorded in blood lead, urinary coproporphyrin, and basophilic stippled red blood cells of the exposed group in comparison to the control group. Central nervous system symptoms (insomnia, fatigue, weakness, and drowsiness) were reported by 50% and other symptoms such as abdominal colic and constipation weremore » reported by 41% of the exposed group. Blue line on the gum was detected only on 2% of the exposed group. Strong associations between exposure to lead and the prevalence of central nervous system symptoms, abdominal colic, and constipation were recorded.

2013-11-01

The psychometric properties of a questionnaire developed to assess symptoms of anxiety disorders (SCARED-71) were compared between two groups of children: children with high-functioning autism spectrum disorder and comorbid anxiety disorders (ASD-group; n = 115), and children with anxiety disorders (AD-group; n = 122). Anxiety disorders were established with a semi-structured interview (ADIS-C/P), using child- as well as parent-report. Internal consistency, construct validity, sensitivity, specificity, and discriminant validity of the SCARED-71 was investigated. Results revealed that the psychometric properties of the SCARED-71 for the ASD-group were quite comparable to the AD-group, however, the discriminant validity of the SCARED-71 child-report was less in the ASD-group. Raising the parental cutoffs of the SCARED-71 resulted in higher specificity rates, which suggests that research should focus more on establishing alternative cutoffs for the ASD-population.

Asian communities in North America include large numbers of immigrants with limited English proficiency. Hepatitis B virus (HBV) infection is endemic in most Asian countries and, therefore, Asian immigrant groups have high rates of chronic HBV infection. We conducted a group-randomized trial to evaluate the effectiveness of a hepatitis B English as a second language (ESL) educational curriculum for Asian immigrants. Eighty ESL classes were randomized to experimental (hepatitis B education) or control (physical activity education) status. Students who reported they had not received a HBV test (at baseline) completed a follow-up survey 6 months after randomization. The follow-up survey assessed recent HBV testing and HBV-related knowledge. Provider reports were used to verify self-reported HBV tests. The study group included 218 students who reported they had not been tested for HBV. Follow-up surveys were completed by 180 (83%) of these students. Provider records verified HBV testing for 6% of the experimental group students and 0% of the control group students (P = 0.02). Experimental group students were significantly (P < 0.05) more likely than control group students to know that immigrants have high HBV infection rates, HBV can be spread during sexual intercourse and by sharing razors, and HBV infection can cause liver cancer. Our ESL curriculum had a meaningful impact on HBV-related knowledge and a limited impact on HBV testing levels. Future research should evaluate the effectiveness of ESL curricula for other immigrant groups and other health topics, as well as other intervention approaches to increasing levels of HBV testing in Asian immigrant communities.

2015-09-01

Music performance anxiety affects numerous musicians, with many of them reporting impairment of performance due to this problem. This exploratory study investigated the effects of virtual reality exposure training on students with music performance anxiety. Seventeen music students were randomly assigned to a control group (n=8) or a virtual training group (n=9). Participants were asked to play a musical piece by memory in two separate recitals within a 3-week interval. Anxiety was then measured with the Personal Report of Confidence as a Performer Scale and the S-Anxiety scale from the State-Trait Anxiety Inventory (STAI-Y). Between pre- and post-tests, the virtual training group took part in virtual reality exposure training consisting of six 1-hour long sessions of virtual exposure. The results indicate a significant decrease in performance anxiety for musicians in the treatment group for those with a high level of state anxiety, for those with a high level of trait anxiety, for women, and for musicians with high immersive tendencies. Finally, between the pre- and post-tests, we observed a significant increase in performance quality for the experimental group, but not for the control group.

Spirituality and the big five personality traits may be risk or protective factors for coping with stress. We hypothesized young adults who reported higher spirituality ratings would demonstrate lower sympathetic nervous system arousal and better emotional coping when exposed to a laboratory stressor compared to those who rated themselves lower in spirituality. We also compared spirituality groups on trait anger, neuroticism, conscientiousness, extraversion, agreeableness and openness to experience. Eighty participants completed trait-state anger, personality and spirituality questionnaires and were grouped into low, average and high spirituality. Participants' physiological responses were monitored before and during a stressful event. Significant differences were found between low, average and high spirituality groups' respiration rate and emotional response to the stressor. Significant differences were also found between spirituality groups in extraversion, agreeableness, conscientiousness, trait anger and neuroticism. Females reported higher levels of spirituality and conscientiousness than males.

In adulthood, depressive mood is often comorbid with ADHD, but its role in ADHD-inattentiveness and especially relations with mind wandering remains to be elucidated. This study investigated the effects of laboratory-induced dysphoric mood on task-unrelated mind wandering and its consequences on cognitive task performance in college students with high (n = 46) or low (n = 44) ADHD-Inattention symptomatology and Hyperactivity/Impulsivity symptoms in the normal range. These non-clinical high/low ADHD-Inattention symptom groups underwent negative or positive mood induction after which mind wandering frequency was measured in a sustained attention (SART), and a reading task. Effects of ruminative response style and working memory capacity on mind wandering frequency were also investigated. Significantly higher frequencies of self -reported mind wandering in daily life, in the SART and reading task were reported in the ADHD-Inattention symptom group, with detrimental effects on text comprehension in the reading task. Induced dysphoric mood did specifically enhance the frequency of mind wandering in the ADHD-Inattention symptom group only during the SART, and was related to their higher self-reported intrusive ruminative response styles. Working memory capacity did not differ between high/low attention groups and did not influence any of the reported effects. These combined results suggest that in a non-clinical sample with high ADHD-inattention symptoms, dysphoric mood and a ruminative response style seem to be more important determinants of dysfunctional mind wandering than a failure in working memory capacity/executive control, and perhaps need other ways of remediation, like cognitive behavioral therapy or mindfulness training.

The goal of this study was to identify meaningful groups of sixth graders with common characteristics based on teacher ratings of assets and maladaptive behaviors, describe dropout rates for each group, and examine the validity of these groups using students' self-reports. The sample consisted of racially diverse students (n = 675) attending sixth grade in public schools in Northeast Georgia. The majority of the sample was randomly selected; a smaller group was identified by teachers as high risk for aggression. Based on teacher ratings of externalizing behaviors, internalizing problems, academic skills, leadership, and social assets, latent profile analysis yielded 7 classes that can be displayed along a continuum: Well-Adapted, Average, Average-Social Skills Deficit, Internalizing, Externalizing, Disruptive Behavior with School Problems, and Severe Problems. Dropout rate was lowest for the Well-adapted class (4%) and highest for the Severe Problems class (58%). However, students in the Average-Social Skills Deficit class did not follow the continuum, with a large proportion of students who abandoned high school (29%). The proportion of students identified by teachers as high in aggression consistently increased across the continuum from none in the Well-Adapted class to 84% in the Severe Problems class. Students' self-reports were generally consistent with the latent profile classes. Students in the Well-Adapted class reported low aggression, drug use, and delinquency, and high life satisfaction; self-reports went in the opposite direction for the Disruptive Behaviors with School Problems class. Results highlight the importance of early interventions to improve academic performance, reduce externalizing behaviors, and enhance social assets. (c) 2015 APA, all rights reserved).

Objective Compared to non-bingers, binge drinkers are more likely to drive while intoxicated. The extent to which binge frequency impacts confidence in driving and subsequent driving impairment is unknown. This study compared the effects of an experimenter-delivered alcohol binge on subjective impairment and simulated driving ability in female High and Low Frequency bingers. Methods Female drinkers were assigned to High Frequency (n=30) or Low Frequency (n=30) binge groups based on their Alcohol Use Questionnaire responses. At 30-minute intervals within a two-hour period, participants received either a placebo drink (n=15 per group) or a 0.2 g/kg dose of alcohol (n=15 per group; cumulative dose 0.8 g/kg). Self-reported impairment, driving confidence, and simulated driving were then measured. Results Self-reported confidence in driving was significantly lower after alcohol than after placebo in Low Frequency but not High Frequency bingers. Self-reported impairment and collisions during simulated driving were significantly greater after alcohol than after placebo in both Low Frequency and High Frequency bingers. Conclusions The impairing effects of a single alcohol binge on driving ability in females are not influenced by binge frequency. However, high binge frequency may be associated with a less cautious approach to post-binge driving. PMID:21542027

Previous studies that examined age differences in hypermnesia reported inconsistent results. The present experiment investigated whether the different study materials in these studies were responsible for the inconsistency. In particular, the present experiment examined whether the use of a video, as opposed to words and pictures, would eliminate previously reported age differences in hypermnesia. Fifteen college students and 15 older adults viewed a 3-minute video clip followed by two free-recall tests. The results indicated that older adults, as a whole, did not show hypermnesia. However, when older adults were divided into low and high memory groups based on test 1 performance, the high memory group showed hypermnesia whereas the low memory group did not show hypermnesia. The older adults in the low memory group were significantly older than the older adults in the high memory group - indicating that hypermnesia is inversely related to age in older adults. Reminiscence did not show an age-related difference in either the low or high memory group whereas inter-test forgetting did show an age difference in the low memory group. As expected, older adults showed greater inter-test forgetting than young adults in the low memory group. Findings from the present experiment suggest that video produces a pattern of results that is similar to the patterns obtained when words and pictures are used as study material. Thus, it appears that the nature of study material is not the source of inconsistency across the previous studies.

Chronic pain is the most common reason for medical cannabis certification. Data regarding alcohol use and risky drinking among medical cannabis patients with pain is largely unknown. Therefore, we examined the prevalence and correlates of alcohol use and risky drinking in this population. Participants completed surveys regarding demographics, pain-related variables, anxiety, cannabis use, and past six-month alcohol consumption. Alcohol use groups were defined using the AUDIT-C [i.e., non-drinkers, low-risk drinkers, and high-risk drinkers (≥4 for men and ≥3 for women)] and compared on demographic characteristics, pain measures, anxiety, and cannabis use. Overall, 42% (n=330/780) were non-drinkers, 32% (n=251/780) were low-risk drinkers, and 26% (n=199/780) were high-risk drinkers. Compared to non-drinkers, low- and high-risk drinkers were significantly younger whereas a larger proportion of low-risk drinkers reported being African-American compared to non- or high-risk drinkers. High-risk drinkers reported significantly lower pain severity/interference compared to the other groups; high-risk drinkers were also less likely to be on disability compared to other groups. A multinomial logistic regression showed that patients reporting lower pain severity and less disability had greater odds of being classified a high-risk drinker. High-risk drinking appears common among medical cannabis patients. Future research should examine whether such use is concurrent or consecutive, and the relationship of such co-use patterns to consequences. Nevertheless, individuals treating patients reporting medical cannabis use for pain should consider alcohol consumption, with data needed regarding the efficacy of brief alcohol interventions among medical cannabis patients.

The high intake of game meat in populations with a subsistence-based diet may affect their blood lipids and health status. To examine the association between diet and circulating levels of blood lipid levels in a northern Swedish population. We compared a group with traditional lifestyle (TLS) based on reindeer herding (TLS group) with those from the same area with a non-traditional lifestyle (NTLS) typical of more industrialized regions of Sweden (NTLS group). The analysis was based on self-reported intake of animal source food (i.e. non-game meat, game meat, fish, dairy products and eggs) and the serum blood level of a number of lipids [total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), triglycerides (TG), glycerophospholipids and sphingolipids]. The TLS group had higher cholesterol, LDL and HDL levels than the reference group. Of the TLS group, 65% had cholesterol levels above the threshold for increased risk of coronary heart disease (≥ 240 mg/dl), as compared to 38% of the NTLS group. Self-reported consumption of game meat was positively associated with TC and LDL. The high game meat consumption of the TLS group is associated with increased cholesterol levels. High intake of animal protein and fat and low fibre is known to increase the risk of cardiovascular disease, but other studies of the TLS in northern Sweden have shown comparable incidences of cardiovascular disease to the reference (NTLS) group from the same geographical area. This indicates that factors other than TC influence disease risk. One such possible factor is dietary phospholipids, which are also found in high amounts specifically in game meat and have been shown to inhibit cholesterol absorption.
The Effect of Co-occurring Substance Use on Gamma-hydroxybutyric Acid Withdrawal Syndrome.

2016-01-01

Gamma-hydroxybutyric acid (GHB) withdrawal is a complex syndrome which can be potentially life-threatening. Additionally, GHB-dependent patients frequently report co-occurring substance use of other psychoactive drugs. We assessed the add-on effect of co-use on GHB withdrawal symptoms. We conducted an open-label, pretest-posttest design study with 95 patients selected from 229 inpatients admitted for detoxification, who were divided into GHB only (GO, n = 40), GHB plus sedatives (GSE, n = 38), and GHB plus stimulants (GST, n = 17) groups. GHB withdrawal was evaluated by means of the Subjective Withdrawal Scale. Co-use add-on effects on the severity of withdrawal symptoms were evaluated 2.5 hours after the last illicit GHB self-administration (T1) when withdrawal was expected and 2.5 hours later, after administration of a very low dose of pharmaceutical GHB (T2). The GO group reported high scores of psychomotor retardation symptoms at both T1 and T2, and also high cravings, agitation, and restlessness at T1, and anxiety at T2. The GSE group reported the highest score in psycho-autonomic distress symptoms at both T1 and T2, whereas the GST group reported the highest score in psycho-motor stress factor at T2. There was no significant difference in withdrawal intensity in all symptom clusters between T1 and T2 for both GSE and GO groups. However, after 5 hours, the GST group reported significant decreases in intensity for all symptoms except for psycho-motor stress. At T1, GST and GSE groups reported more muscle twitches than the GO group as a significant add-on effect to the GHB withdrawal. At T2, the GST group experienced more agitation (P = 0.009), restlessness (P = 0.001), and rapid pulse (P = 0.034) than the GO group. Co-use, especially of stimulants, caused an add-on effect on the GHB withdrawal symptoms within the first 5 hours.

This study examined the relationships between parental posttraumatic stress symptoms (PTSS), child PTSS, and parent-child concordance for child PTSS. Participants were children with cancer (n = 199), and healthy children (n = 108) and their parents. Children self-reported on PTSS and parents completed measures of child and parent PTSS. In the cancer group, child and parent reports of child PTSS were significantly correlated with no mean differences between reporters. In contrast, correlations were non-significant in the control group, and parents reported significantly lower levels of child PTSS than children. Increased parental PTSS was associated with better concordance in the cancer group but not in the control group. In fact, in the cancer group, parent-child concordance was strongest at the highest level of parental PTSS. Parents of children with cancer were found to be accurate reporters of their children's distress, even with high levels of reported personal distress. In contrast, parents of healthy children appear primarily influenced by personal distress when reporting child PTSS. Although multiple informant assessments are always desirable, it appears that utilization of a single informant may be reasonable in the cancer setting when access to informants is limited.

Annual Research Briefs - 2000: Center for Turbulence Research

NASA Technical Reports Server (NTRS)

2000-01-01

This report contains the 2000 annual progress reports of the postdoctoral Fellows and visiting scholars of the Center for Turbulence Research (CTR). It summarizes the research efforts undertaken under the core CTR program. Last year, CTR sponsored sixteen resident Postdoctoral Fellows, nine Research Associates, and two Senior Research Fellows, hosted seven short term visitors, and supported four doctoral students. The Research Associates are supported by the Departments of Defense and Energy. The reports in this volume are divided into five groups. The first group largely consists of the new areas of interest at CTR. It includes efficient algorithms for molecular dynamics, stability in protoplanetary disks, and experimental and numerical applications of evolutionary optimization algorithms for jet flow control. The next group of reports is in experimental, theoretical, and numerical modeling efforts in turbulent combustion. As more challenging computations are attempted, the need for additional theoretical and experimental studies in combustion has emerged. A pacing item for computation of nonpremixed combustion is the prediction of extinction and re-ignition phenomena, which is currently being addressed at CTR. The third group of reports is in the development of accurate and efficient numerical methods, which has always been an important part of CTR's work. This is the tool development part of the program which supports our high fidelity numerical simulations in such areas as turbulence in complex geometries, hypersonics, and acoustics. The final two groups of reports are concerned with LES and RANS prediction methods. There has been significant progress in wall modeling for LES of high Reynolds number turbulence and in validation of the v(exp 2) - f model for industrial applications.
Influence of Yo-Yo IR2 Scores on Internal and External Workloads and Fatigue Responses of Tag Football Players during Tournament Competition

PubMed Central

2015-01-01

The purpose of this study was to: a) identify changes in jump height and perceived well-being as indirect markers of fatigue, b) determine the internal and external workloads performed by players, and c) examine the influence of Yo-Yo IR2 on changes in jump height, perceived well-being and internal and external workloads during a tag football tournament. Microtechnology devices combined with heart rate (HR) chest straps provided external and internal measures of match work-rate and workload for twelve male tag football players during the 2014 Australian National Championships. Jump height and perceived well-being were assessed prior to and during the tournament as indirect measures of fatigue. Changes in work-rate, workload and fatigue measures between high- and low-fitness groups were examined based on players’ Yo-Yo IR2 score using a median split technique. The low- and high-fitness groups reported similar mean HR, PlayerloadTM/min, and distance/min for matches, however the low-fitness group reported higher perceived match-intensities (ES = 0.90–1.35) for several matches. Further, the high-fitness group reported higher measures of tournament workload, including distance (ES = 0.71), PlayerloadTM (ES = 0.85) and Edwards’ training impulse (TRIMP) (ES = 1.23) than the low-fitness group. High- and low-fitness groups both showed large decreases (ES = 1.46–1.49) in perceived well-being during the tournament, although jump height did not decrease below pre-tournament values. Increased Yo-Yo IR2 appears to offer a protective effect against player fatigue despite increased workloads during a tag football tournament. It is vital that training programs adequately prepare tag football players for tournament competition to maximise performance and minimise player fatigue. PMID:26465599

Recreational drug use has been found to be associated with high-risk sexual behaviour and with sexually transmitted infections (STI). This study is the first to assess the prevalence of drug use among swingers (heterosexuals who, as a couple, practise mate swapping or group sex, and/or visit sex clubs for couples), and its association with high-risk sexual behaviour and STI. We recruited individuals who self-identified as swingers and visited our STI clinic (from 2009 to 2012, South Limburg, The Netherlands). Participants (n=289; median age 45 years; 49% female) filled in a self-administered questionnaire on their sexual and drug use behaviour while swinging, over the preceding 6 months. We assessed associations between sexual behaviour, drug use and STI diagnoses (Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), syphilis, HIV and hepatitis B) using logistic regression analyses. Overall, the prevalence of CT and/or NG was 13%. No other STIs were observed. Seventy-nine percent of swingers reported recreational drug use (including alcohol and use of erectile dysfunction drugs); 46% of them reported multiple drug use. Recreational drug use excluding alcohol and erectile dysfunction drugs (reported by 48%) was associated with high-risk behaviours in men and women. Drug use was independently associated with STI in female swingers, especially those who practice group sex. High rates of multiple drug use, as well as risky sexual behaviour and STIs among swingers, warrant paying more attention to this key population in prevention and care, as they are a risk group that is generally under-recognised and underserved in care.

2011-01-01

Background Self-management is the cornerstone of diabetes control and prevention of complications; however, it is undetermined whether differences in intention to adopt healthy lifestyles and actual healthy behavior exist across race/ethnic groups. This study evaluated the differences across racial-ethnic groups in self-reported medical advice received and health intentions and behaviors among adults with type 2 diabetes mellitus. Methods A cross-sectional analysis of the 2007 SHIELD US survey ascertained self-reported health intentions and behaviors for regular exercise, diet, and weight management among Non-Hispanic Caucasian (n = 2526), Non-Hispanic African-American (n = 706), and Hispanic (n = 179) respondents with type 2 diabetes. Results A similar proportion of respondents from each race-gender group (43%-56%) reported receiving healthcare advice to increase their exercise (P = 0.32). Significantly more minorities reported an intention to follow the exercise recommendation compared with Non-Hispanic Caucasians (P = 0.03). More Non-Hispanic African-American (29%) and Hispanic (27%) men reported exercising regularly compared with other race-gender groups (P = 0.02). Significantly more Non-Hispanic Caucasian women (74%) and Hispanic women (79%) reported trying to lose weight compared with other groups (P < 0.0001). Conclusions Differences in health intentions and healthy behaviors were noted across race-gender groups. More Non-Hispanic African-American men reported an intention to follow advice on exercising and self-report of exercising regularly was also higher compared with other race-gender groups. More Hispanic men reported high physical activity levels than other groups. Despite an increased willingness to follow healthcare recommendations for diet, >50% of respondents were obese among all race-gender groups. PMID:21729303

To analyze the epidemiological characteristics of meningococcal meningitis and provide evidences for disease control. The method of descriptive epidemiology has been used to analyze the data collected. A total of 419 cases were reported with meningococcal meningitis between 1996-2007, annual incidence rate was 0.07/100,000. 68 cases were dead and mortatity was 16.23% . Highly sporadic distribution by areas was observed in the cases reported. And the incidence peak was between January and April. The aged was mainly at 0-9 years There was trace that the incidence move to aged at 10 19 years old in recent years. The in-cidence rate was higher in male than that in female. And it was mainly attacked in peasants, students and children left-behined at home. Outbreaks had occasionally occurred in Guangxi. The first outbreak caused by Neisseria meningitidis group C in China was reported. The strains isola-ted mainly were with Neisseria meningitidis group A, which accounting for 61.53% of the strains,followed by group C(15. 38%)and Group B (7.69%). Group A was found to be 100% re-sistant to SMZ-TMP,and both group C and B were 100% resistant to sulfanilamide. 1.28% the prevalence of carrier was confirmed by the throat swabs. The positive rate of titer to group A and C were 29. 95o and 21. 720 respectively, and the mean titers were 4.57 microg/ml and 1.70 microg/ml re-spectively. The characteristics of Meningococcal meningitis are summarized as low incidence,high mortabity,highly sporadic distribution, grouping diversity and increasing incidence in older population. Comprehensive measures with the priority of vaccination is the key measure for meningococcal meningitis control.
Childhood callous-unemotional traits moderate the relation between parenting distress and conduct problems over time.

The present short-term longitudinal study examines the bidirectional effects among paternal-reported and maternal-reported involvement, distress and conduct-problems (CP) in children ages 7–12 years with callous-unemotional (CU) traits as a potential moderator. Latent profile analysis revealed four groups: high, moderate, decreasing, and low on CU traits. Findings suggested that children high on CU traits were at higher risk to exhibit CP and were more likely to experience low parental-involvement and high parental-distress compared to children with low, decreasing, and moderate CU traits. Findings from the cross-lagged structural equation model suggested that high levels of CP predicted increases in parenting distress, and this was shown for youth with high levels of CU traits. In turn, parental-reported distress predicted increases in CP for children in the low and decreasing CU groups. A negative bidirectional association between maternal-involvement and CP was also identified. Findings extend cross-sectional research showing parents become distressed by CP behaviors, particularly when accompanied by high CU traits.

This document is the report of a task group of the Radiation Therapy Committee of the AAPM and has been prepared primarily to advise hospital physicists involved in external beam treatment of patients with pelvic malignancies who have high atomic number (Z) hip prostheses. The purpose of the report is to make the radiation oncology community aware of the problems arising from the presence of these devices in the radiation beam, to quantify the dose perturbations they cause, and, finally, to provide recommendations for treatment planning and delivery. Some of the data and recommendations are also applicable to patients having implanted high-Z prosthetic devices such as pins, humeral head replacements. The scientific understanding and methodology of clinical dosimetry for these situations is still incomplete. This report is intended to reflect the current state of scientific understanding and technical methodology in clinical dosimetry for radiation oncology patients with high-Z hip prostheses.

2008-04-01

Prolonged QT interval and QT dispersion have been reported in patients with eating disorders. Although the factors that cause prolongation remain unclear, mood states such as anxiety have been reported to influence QT interval and dispersion, probably via the autonomic nervous system. Therefore the aim of the present paper was to investigate mood effect on prolonged QT interval and QT dispersion. The subjects were 47 female anorexia nervosa (AN) and 48 female bulimia nervosa (BN) patients. In all of the patients, serum electrolyte levels were normal. QT interval and QT dispersion were measured from 12-lead electrocardiographic recordings. Mood states in each patient were measured using a Profile of Mood States (POMS) evaluation, and the patients were divided into high- and low-score groups for each POMS subscale. The differences in QT variables were compared between the two groups for each subscale. In the BN group, QT interval and QT dispersion in the high depression score group were significantly longer than those in the low depression score group, and QT dispersion was significantly greater in the high anxiety score group than in the low anxiety score group. In addition, QT interval and QT dispersion were significantly correlated with depression scores. In the AN group there were no significant differences in QT interval or QT dispersion between the high- and low-score groups for any POMS subscale. BN patients with worse states of depression or anxiety had longer QT intervals and larger QT dispersion. In BN patients, mood disturbance might increase the risk of arrhythmias.

In Indiana, high school football coaches are required to complete a coaching education course with material related to concussion awareness, equipment fitting, heat emergency preparedness, and proper technique. Some high schools have also opted to implement a player safety coach (PSC). The PSC, an integral component of USA Football's Heads Up Football (HUF) program, is a coach whose primary responsibility is to ensure that other coaches are implementing proper tackling and blocking techniques alongside other components of the HUF program. To compare injury rates in Indiana high school football teams by their usage of a PSC or online coaching education only. Cohort study; Level of evidence, 2. Athletic trainers (ATs) evaluated and tracked injuries at each practice and game during the 2015 high school football season. Players were drawn from 6 teams in Indiana. The PSC group, which used the PSC component, was comprised of 204 players from 3 teams. The "education only" group (EDU), which utilized coaching education only, was composed of 186 players from 3 teams. Injury rates and injury rate ratios (IRRs) were reported with 95% confidence intervals (CIs). During 25,938 athlete-exposures (AEs), a total of 149 injuries were reported, of which 54 (36.2%) and 95 (63.8%) originated from the PSC and EDU groups, respectively. The practice injury rate was lower in the PSC group than the EDU group (2.99 vs 4.83/1000 AEs; IRR, 0.62; 95% CI, 0.40-0.95). The game injury rate was also lower in the PSC group than the EDU group (11.37 vs 26.37/1000 AEs; IRR, 0.43; 95% CI, 0.25-0.74). When restricted to concussions only, the rate was lower in the PSC group (0.09 vs 0.73/1000 AEs; IRR, 0.12; 95% CI, 0.01-0.94), although only 1 concussion was reported in the PSC group. No differences were found in game concussion rates (0.60 vs 4.39/1000 AEs; IRR, 0.14; 95% CI, 0.02-1.11). Findings support the PSC as an effective method of injury mitigation in high school football. Future research should seek to replicate this study using larger samples from additional states.

No differences were found in game concussion rates (0.60 vs 4.39/1000 AEs; IRR, 0.14; 95% CI, 0.02-1.11). Conclusion: Findings support the PSC as an effective method of injury mitigation in high school football. Future research should seek to replicate this study using larger samples from additional states. PMID:27275000

High school students are reported to be excessively sleepy, resulting in decreased academic performance, increased psycho-social problems and increased risk of morbidity and mortality from accidents. Early school start times have been noted to contribute to this problem. This report attempts to confirm the relationship of early school start times with decreased sleep and increased sleepiness. We examined sophomore and junior students in 2 local high schools with different start times and measured the amount of time slept and sleepiness. We found that students at the early start school reported reduced sleep time and more sleepiness than their counterparts at the later starting school. Early school start times are associated with student reports of less sleep and increased sleepiness. Further studies in larger groups are recommended in view of the potential significant impact of sleep deprivation in this age group.

Barium esophagrams are a frequently performed test, and radiological observations about potential abnormal esophageal motility, such as tertiary contractions, are commonly reported. We sought to assess the correlation between tertiary waves, and in particular isolated tertiary waves, on esophagrams and findings on non-synchronous high-resolution esophageal manometry. We retrospectively reviewed reports of esophagrams performed at a tertiary referral center and identified patients in whom tertiary waves were observed and a high-resolution esophageal manometry had been performed. We defined two groups; group 1 was defined as patients with isolated tertiary waves, whereas group 2 had tertiary waves and evidence of achalasia or an obstructing structural abnormality on the esophagram. We collected data on demographics, dysphagia score, associated findings on esophagram, and need for intervention. We reviewed the reports of 2100 esophagrams of which tertiary waves were noted as an isolated abnormality in 92, and in association with achalasia or a structural obstruction in 61. High-resolution manometry was performed in 17 patients in group 1, and five had evidence of a significant esophageal motility disorder and 4 required any intervention. Twenty-one patients in group 2 underwent manometry, and 18 had a significant esophageal motility disorder. An isolated finding of tertiary waves on an esophagram is rarely associated with a significant esophageal motility disorder that requires intervention. All patients with isolated tertiary waves who required intervention had a dysphagia to liquids. Tertiary contractions, in the absence of dysphagia to liquids, indicate no significant esophageal motility disorder. © 2014 International Society for Diseases of the Esophagus.

Casino employees are exposed to disproportionately high levels of gambling, drinking and smoking compared to other occupations. Because of their occupation, they have the opportunity to detect and prevent pathological gambling (PG). To identify differences in the mental health status and social attitudes towards PG among casino workers in South Korea depending upon whether they report any gambling problems. Data were collected from 388 full-time casino employees. This data provided information about the prevalence of gambling problems, alcohol and tobacco use and depression. Employees were grouped according to their scores on the Korean version of South Oaks Gambling Screen (SOGS), and those employees who gambled without experiencing any gambling problems (Group NP: SOGS = 0) and those who reported any gambling problems (Group P: SOGS > 0) were compared. An exploratory factor analyses identified the domains of casino employee social attitudes towards gambling. Employees who reported gambling problems (Group P) reported a higher prevalence of smoking, alcohol problems and depression (P < 0.01) compared to employees who did not report gambling problems (Group NP). The primary employee social attitude towards gambling was identified by the factor of 'Disease concept/social awareness'. Group NP reported more positive attitudes in this domain than Group P (P < 0.01). Employees who reported any gambling problems reported a less positive attitude towards developing the public health system to be responsive to gambling problems. These findings indicate a need to develop health education programmes that focus more specifically on casino employees with gambling problems.

Context: Some healthy athletes report high levels of baseline concussion symptoms, which may be attributable to several factors (eg, illness, personality, somaticizing). However, the role of baseline symptoms in outcomes after sport-related concussion (SRC) has not been empirically examined. Objective: To determine if athletes with high symptom scores at baseline performed worse than athletes without baseline symptoms on neurocognitive testing after SRC. Design: Cohort study. Setting: High school and collegiate athletic programs. Patients or Other Participants: A total of 670 high school and collegiate athletes participated in the study. Participants were divided into groups with either no baseline symptoms (Postconcussion Symptom Scale [PCSS] score = 0, n = 247) or a high level of baseline symptoms (PCSS score > 18 [top 10% of sample], n = 68). Main Outcome Measure(s): Participants were evaluated at baseline and 2 to 7 days after SRC with the Immediate Post-concussion Assessment and Cognitive Test and PCSS. Outcome measures were Immediate Post-concussion Assessment and Cognitive Test composite scores (verbal memory, visual memory, visual motor processing speed, and reaction time) and total symptom score on the PCSS. The groups were compared using repeated-measures analyses of variance with Bonferroni correction to assess interactions between group and time for symptoms and neurocognitive impairment. Results: The no-symptoms group represented 38% of the original sample, whereas the high-symptoms group represented 11% of the sample. The high-symptoms group experienced a larger decline from preinjury to postinjury than the no-symptoms group in verbal (P = .03) and visual memory (P = .05). However, total concussion-symptom scores increased from preinjury to postinjury for the no-symptoms group (P = .001) but remained stable for the high-symptoms group. Conclusions:> Reported baseline symptoms may help identify athletes at risk for worse outcomes after SRC. Clinicians should examine baseline symptom levels to better identify patients for earlier referral and treatment for their injury. Additional investigation of baseline symptoms is warranted to help delineate the type and severity of premorbid symptoms. PMID:26885702

Overlap syndrome shares features of both asthma and chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate characteristics of overlap syndrome and their effect on self-rated health (SRH). We analyzed data from the Fourth Korea National Health and Nutrition Examination Survey of 2007-2009. Subjects with acceptable spirometry and available wheezing history were included. Subjects were classified into four groups based on forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) results and the presence or absence of self-reported wheezing for the previous 12 months: 1) COPD group, defined as having FEV1/FVC <0.7 without self-reported wheezing history; 2) asthma group, defined as having self-reported wheezing history without FEV1/FVC <0.7; 3) overlap syndrome group, having both FEV1/FVC <0.7 and wheezing history; and 4) non-obstructive disease (NOD) group, having neither FEV1/FVC <0.7 nor self-reported wheezing. SRH was categorized as better or lower based on responses to a questionnaire. From a total 9,104 subjects, 700 were assigned to the COPD group, 560 to the asthma group, 210 to the overlap syndrome group, and 7,634 to the NOD group. Compared to the other groups, subjects in the overlap syndrome group were more likely to have low lung function, a high proportion of smokers, low socioeconomic status, short education duration, lower SRH, and past diagnosis of pulmonary tuberculosis or bronchiectasis. Multiple logistic regression analysis revealed that both overlap syndrome and asthma groups were independently associated with lower SRH after adjustment for age, sex, socioeconomic status, education level, smoking status, comorbidities, and lung function. Female, old age, low education level, low economic status, smoker and other comorbidities were also associated with lower SRH. Overlap syndrome was accompanied by high morbidity and was associated with lower SRH, which needs more appropriate care.

Research on the effectiveness of distraction as a method of pain control is inconclusive. One mechanism pertains to the motivational relevance of distraction tasks. In this study the motivation to engage in a distraction task during pain was experimentally manipulated. Undergraduate students (N=73) participated in a cold pressor test (CPT) and were randomly assigned to three groups: a distraction-only group performed a tone-detection task during the CPT, a motivated-distraction group performed the same task and received a monetary reward for good task performance, and a control group did not perform the tone-detection task. Results indicated that engagement in the distraction task was better in the motivated-distraction group in comparison with the distraction-only group. Participants in both distraction groups experienced less pain compared to the control group. There were no overall differences in pain intensity between the two distraction groups. The effect of distraction was influenced by the level of catastrophic thinking about pain. For low catastrophizers, both distraction groups reported less pain as compared to the non-distracted control group. This was not the case for high catastrophizers. For high catastrophizers it mattered whether the distraction task was motivationally relevant: high catastrophizers reported less intense pain in the motivated-distraction group, as compared to the non-distracted control group. We conclude that increasing the motivational relevance of the distraction task may increase the effects of distraction, especially for those who catastrophize about pain.

The current study examined the indirect effect of maternal and paternal emotional and physical maltreatment on affective and behavioral symptoms of oppositional defiant disorder (ODD) through parent-child relationship quality; gender and overall ODD symptoms were examined as moderators. Participants included 2,362 emerging adults who completed questionnaires about parental emotional and physical maltreatment, parent-child relationship quality, and affective and behavioral ODD symptoms. These characteristics were compared across parent and child gender (i.e., maternal and paternal effects as well as male and female differences) as well as participants reporting high and low ODD symptoms. In the low ODD group, indirect effects of emotional maltreatment occurred in all parent-child dyads except the mother-son dyad, whereas in the high ODD group, indirect effects occurred only in the father-son dyad. Indirect effects of physical maltreatment occurred only in the father-son dyad in the low ODD group, and only in the mother-daughter dyad on behavioral ODD symptoms in the high ODD group. The results suggest that specific parent-child gender dyads respond differently, warranting further investigation of gender effects. Moreover, emerging adults in the low ODD symptoms group demonstrated a positive association between parental maltreatment and ODD symptoms and a negative association between parent-child relationship quality and ODD symptoms, whereas those high in the high ODD symptoms group did not demonstrate these associations. That is, emerging adults reporting high ODD symptoms demonstrated no relationship between their ODD symptoms and harsh parenting, suggesting an ineffective coercive process.

We investigated the association between income-education groups and incident coronary heart disease (CHD) in a national prospective cohort study. The REasons for Geographic And Racial Differences in Stroke study recruited 30,239 black and white community-dwelling adults between 2003 and 2007 and collected participant-reported and in-home physiologic variables at baseline, with expert adjudicated CHD endpoints during follow-up. Mutually exclusive income-education groups were: low income (annual household income <$35,000)/low education (< high school), low income/high education, high income/low education, and high income/high education. Cox models estimated hazard ratios (HR) for incident CHD for each exposure group, examining differences by age group. At baseline, 24,461 participants free of CHD experienced 809 incident CHD events through December 31, 2011 (median follow-up 6.0 years; interquartile range 4.5-7.3 years). Those with low income/low education had the highest incidence of CHD (10.1 [95% CI 8.4-12.1]/1000 person-years). After full adjustment, those with low income/low education had higher risk of incident CHD (HR 1.42 [95% CI: 1.14-1.76]) than those with high income/high education, but findings varied by age. Among those aged <65 years, compared with those reporting high income/high education, risk of incident CHD was significantly higher for those reporting low income/low education and low income/high education (adjusted HR 2.07 [95% CI 1.42-3.01] and 1.69 [95% CI 1.30-2.20], respectively). Those aged ≥ 65 years, risk of incident CHD was similar across income-education groups after full adjustment. For younger individuals, low income, regardless of education, was associated with higher risk of CHD, but not observed for ≥ 65 years. Findings suggest that for younger participants, education attainment may not overcome the disadvantage conferred by low income in terms of CHD risk, whereas among those ≥ 65 years, the independent effects of income and education are less pronounced.
Responses to false physiological feedback in individuals with panic attacks and elevated anxiety sensitivity.

Story, Tyler J; Craske, Michelle G

2008-09-01

Participants with elevated anxiety sensitivity and a history of panic attacks were compared to a low anxiety comparison group with respect to physiological and subjective reactivity to false heart-rate feedback and reactivity to a priming procedure. Whereas accurate heart-rate feedback elicited minimal responses, participants across groups showed significant physiological and subjective responses to false feedback. High risk and low risk participants did not differ in heart-rate responses to false feedback, though panic attack frequency did predict physiological and subjective reactions to false feedback in the high risk group. Self-reported nonspecific anxiety was significantly higher in high risk female participants than in low risk female participants, while males did not different in general subjective anxiety. However, high risk participants reported more panic-specific symptoms during the false feedback task than low risk participants, regardless of the sex of the participant. Therefore, although the experimental paradigm appeared to trigger nonspecific anxiety in high risk female participants, panic attack symptoms in reaction to the task were specific to risk group, not sex, and consistent with hypotheses. Surprisingly, the priming procedure did not influence physiological or subjective responses to false feedback in either group. These results raise additional questions regarding the process and impact of interception in individuals with panic attacks, and suggest that false perception of internal changes may contribute to risk for panic disorder when exposed to believable cues.

The potential of methamphetamine, and high-potency crystal methamphetamine in particular, to precipitate psychotic symptoms and psychotic illness is the subject of much speculation internationally. Established psychotic illness is disabling for individuals and costly to society. The aim of this study was to investigate whether use of crystal methamphetamine was associated with greater prevalence of self-reported psychotic illness, compared to use of other forms of methamphetamine. The sample comprised participants interviewed as part of an annual cross-sectional survey of Australian people who inject drugs. Comparisons were made between groups according to the nature of their methamphetamine use: crystal methamphetamine or other forms of methamphetamine. Self-reported diagnoses of psychotic illness and other mental health problems were compared between groups. Predictors of self-reported psychotic illness were examined using multivariable logistic regression analyses. Self-reported psychotic illness was highly prevalent among users of crystal methamphetamine (12.0%), and significantly more so than among users of other forms of methamphetamine (3.9%) (OR=3.36; CI: 1.03-10.97). Significant predictors of self-reported psychosis in the cohort were: use of crystal methamphetamine; dependent use; lack of education beyond high school; and younger age. Highly increased prevalence of self-reported psychotic illness is associated with use of high-potency crystal methamphetamine in people who inject drugs, particularly where there is dependent use. There is an urgent need to develop effective interventions for dependent crystal methamphetamine use; and a need to monitor for symptoms of psychotic illness in drug-using populations.

To report an update of our previous experience using stereotactic body radiation therapy (SBRT) for the primary treatment of prostate cancer, risk stratified by the updated National Comprehensive Cancer Network (NCCN) version 2.2014, reporting efficacy and toxicity in a community hospital setting. From 2007 to 2012, 142 localized prostate cancer patients were treated with SBRT using CyberKnife. NCCN guidelines Version 2.2014 risk groups analyzed included very low (20%), low (23%), intermediate (35%), and high (22%) risk. To further explore group heterogeneity and to comply with new guidelines, we separated our prior intermediate risk group into favorable intermediate and unfavorable intermediate groups depending on how many intermediate risk factors were present (one vs. > one). The unfavorable intermediate group was further analyzed in combination with the high risk group as per NCCN guidelines Version 2.2014. Various dose levels were used over the years of treatment, and have been categorized into low dose (35 Gy, n = 5 or 36.25 Gy, n = 107) and high dose (37.5 Gy, n = 30). All treatments were delivered in five fractions. Toxicity was assessed using radiation therapy oncology group criteria. Five-year actuarial freedom from biochemical failure (FFBF) was 100, 91.7, 95.2, 90.0, and 86.7% for very low, low, intermediate and high risk patients, respectively. A significant difference in 5 year FFBF was noted for patients with Gleason score (GS) ≥8 vs. 7 vs. 5/6 (p = 0.03) and low vs. high dose (p = 0.05). T-stage, pretreatment PSA, age, risk stratification group, and use of ADT did not affect 5-year FFBF. Multivariate analysis revealed GS and dose to be the most predictive factors for 5-year FFBF. Our experience with SBRT for the primary treatment of localized prostate cancer demonstrates favorable efficacy and toxicity comparable to the results reported for IMRT in literature. GS remains the single most important pretreatment predictor of outcome.
A survey of audit activity in general practice.

Hearnshaw, H; Baker, R; Cooper, A

1998-01-01

BACKGROUND: Since 1991, all general practices have been encouraged to undertake clinical audit. Audit groups report that participation is high, and some local surveys have been undertaken, but no detailed national survey has been reported. AIM: To determine audit activities in general practices and the perceptions of general practitioners (GPs) regarding the future of clinical audit in primary care. METHOD: A questionnaire on audit activities was sent to 707 practices from 18 medical audit advisory group areas. The audit groups had been ranked by annual funding from 1992 to 1995. Six groups were selected at random from the top, middle, and lowest thirds of this rank order. RESULTS: A total of 428 (60.5%) usable responses were received. Overall, 346 (85%) responders reported 125.7 audits from the previous year with a median of three audits per practice. There was no correlation between the number of audits reported and the funding per GP for the medical audit advisory group. Of 997 audits described in detail, changes were reported as 'not needed' in 220 (22%), 'not made' in 142 (14%), 'made' in 439 (44%), and 'made and remeasured' in 196 (20%). Thus, 635 (64%) audits were reported to have led to changes. Some 853 (81%) of the topics identified were on clinical care. Responders made 242 (42%) positive comments on the future of clinical audit in primary care, and 152 (26%) negative views were recorded. CONCLUSION: The level of audit activity in general practice is reasonably high, and most of the audits result in change. The number of audits per practice seems to be independent of the level of funding that the medical audit advisory group has received. Although there is room for improvement in the levels of effective audit activity in general practice, continued support by the professionally led audit groups could enable all practices to undertake effective audit that leads to improvement in patient care.

Interventions to improve physical activity among socioeconomically disadvantaged groups: an umbrella review.

2018-05-15

People from socioeconomically disadvantaged population groups are less likely to be physically active and more likely to experience adverse health outcomes than those who are less disadvantaged. In this umbrella review we examined across all age groups, (1) the effectiveness of interventions to improve physical activity among socioeconomically disadvantaged groups, (2) the characteristics of effective interventions, and (3) directions for future research. PubMed/MEDLINE and Scopus were searched up to May 2017 to identify systematic reviews reporting physical activity interventions in socioeconomically disadvantaged populations or sub-groups. Two authors independently conducted study screening and selection, data extraction (one author, with data checked by two others) and assessment of methodological quality using the 'Assessment of Multiple Systematic Reviews' scale. Results were synthesized narratively. Seventeen reviews met our inclusion criteria, with only 5 (30%) reviews being assessed as high quality. Seven (41%) reviews focused on obesity prevention and an additional four focused on multiple behavioural outcomes. For pre school children, parent-focused, group-based interventions were effective in improving physical activity. For children, school-based interventions and policies were effective; few studies focused on adolescents and those that did were generally not effective; for adults, there was mixed evidence of effectiveness but characteristics such as group-based interventions and those that focused on physical activity only were associated with effectiveness. Few studies focused on older adults. Across all ages, interventions that were more intensive tended to be more effective. Most studies reported short-term, rather than longer-term, outcomes and common methodological limitations included high probability of selection bias, low response rates, and high attrition. Interventions can be successful at improving physical activity among children from socioeconomically disadvantaged groups, with evidence for other age groups weak or inconclusive. More high-quality studies in this population group are needed, which adopt strategies to increase recruitment rates and reduce attrition, report longer term outcomes, and provide adequate intervention details, to allow determination of the characteristics of effective interventions. We recommend that the benefits of physical activity be recognised more broadly than obesity prevention in future studies, as this may have implications for the design and appeal of interventions.

Twenty years after the advent of combined antiretroviral therapies (ARTs), there is a growing need for up-to-date information about the daily experience of people living with HIV (PLWH). This study aimed to investigate the relationship between socioepidemiological groups and the types of bothersome symptoms reported by PLWH participating in a national survey in France. We analyzed self-reported bothersome symptoms in a representative sample of PLWH (ANRS-VESPA2 survey), most of whom were receiving ART treatment. PLWH (N = 2505) were grouped into three clusters according to the number of bothersome symptoms reported: Cluster A (low number, n = 1848), Cluster B (moderate number, n = 271), and Cluster C (high number, n = 386). Individuals in Cluster A (low number of bothersome symptoms) were less likely to report all the symptom types investigated. Psychological, sexual, and general symptoms were more likely to be reported in Cluster B (moderate number), whereas gastric-, pain-, and appearance-related symptoms were more likely in Cluster C (high number). In multivariate analyses, women not natives of Sub-Saharan Africa and former/active female injecting drug users were more likely to report a medium or high number of symptoms, and lower adherence to ART. Combining new biomedical strategies with coping mechanisms and providing better support to socially vulnerable PLWH may improve this population's quality of health and daily life.

Male Peer Support to Hostile Sexist Attitudes Influences Rape Proclivity.

Sexual assault affects a large proportion of women in the world. Although most rapes are committed by one man, the act itself may be influenced by many (e.g., the peer group). Hostile sexism (HS) has repeatedly been associated with men's rape proclivity, but the influence exerted by the HS of the peer group on rape proclivity has not been investigated. In this study, we explored the impact of perceived male peer support to HS on participants' rape proclivity. A sample of Spanish undergraduate students from a university in the south of Spain ( N = 134) completed the Ambivalent Sexism Inventory. Immediately afterwards, they received feedback on the supposed sexist responses of a peer group (high vs. low in HS); we kept the benevolent sexism (BS) of the peer group at medium levels. Next, we assessed participants' rape proclivity using acquaintance rape scenarios. Results showed an interaction between participants' own levels of HS and information about the HS of the peer group. Men high in HS reported higher rape proclivity in the high-HS peer-group condition than in the low-HS peer-group condition. By contrast, information on the peer group did not affect self-reported rape proclivity of men low in HS. Results also corroborated the relationship between participants' levels of HS and rape proclivity, and expanded the literature by revealing an unexpected influence of participants' BS on rape proclivity.
The impact of thin idealized media images on body satisfaction: does body appreciation protect women from negative effects?

PubMed

Halliwell, Emma

2013-09-01

This article examines whether positive body image can protect women from negative media exposure effects. University women (N=112) were randomly allocated to view advertisements featuring ultra-thin models or control images. Women who reported high levels of body appreciation did not report negative media exposure effects. Furthermore, the protective role of body appreciation was also evident among women known to be vulnerable to media exposure. Women high on thin-ideal internalization and low on body appreciation reported appearance-discrepancies that were more salient and larger when they viewed models compared to the control group. However, women high on thin-ideal internalization and also high on body appreciation rated appearance-discrepancies as less important and no difference in size than the control group. The results support the notion that positive body image protects women from negative environmental appearance messages and suggests that promoting positive body image may be an effective intervention strategy.

The current study explored the self-experience of persons with Serious Mental Illness (SMI) by investigating the associations between different insight and self-stigma clusters, self-clarity, hope, recovery, and functioning. One hundred seven persons diagnosed with a SMI were administered six scales: self-concept clarity, self-stigma, insight into the illness, hope, recovery, and functioning. Correlations and cluster analyses were performed. Insight, as measured by a self-report scale was not related to any other variable. Self-stigma was negatively associated with self-clarity, hope, recovery and functioning. Three clusters emerged: moderate stigma/high insight (n=31), high stigma/moderate insight (n=28), and low stigma/low insight (n=42). The group with low stigma and low insight had higher mean levels of self-clarity and hope than the other two groups. There were no significant differences between cluster 1 (moderate stigma/high insight) and cluster 2 (high stigma/moderate insight) in all the variables beside self-clarity. The group with moderate stigma and high insight had significantly higher mean levels of self-clarity than the group with high stigma and moderate insight. Results reveal that when people diagnosed with SMI do not have high levels of self-stigma they often report a positive and clear sense of self accompanied with hope, regardless of having low insight.

Intensified surveillance will be vital in the elimination phase to verify Ebola-free status and mitigate potential reemergence of the disease in West Africa. Zero-reporting from high-risk districts is a key strategy for surveillance. Our objective was to implement a pilot investigation to assess the feasibility of using short message service (SMS) texting for daily reporting of Ebola cases under investigation (CUI) in Guinea-Bissau in the context of an ongoing emergency-response training program known as Surveillance Training for Ebola Preparedness (STEP). Prospective cohort (pilot investigation) The reporting period for the SMS pilot was January 24-March 24, 2015. STEP was conducted for two sequential groups during January 19-March 27, 2015 in Bissau, Guinea-Bissau. Training on SMS daily reporting occurred over one hour during the first week of didactic training of each group. Fourteen participants (nine from the first group and five from the second), including one surveillance officer from each of the 13 regions in Guinea-Bissau and one from the national laboratory, were selected as reporters, receiving a simple cell phone for sending SMS indicating the number of CUI for Ebola. The WHO suspect Ebola case definition was used initially and then modified on day 32 of the pilot. The text message was sent to the WiFi-connected smartphone at the Instituto Nacional Saúde Pública (INASA). The smartphone utilised an SMS-gateway application (Ushahidi SMSsync Android App) to upload the data to the Magpi cloud application. The average daily reporting from the first group was 7.7 of 9 (86%) and for the second group was 4.1 of 5 (82%). For the two groups combined, the reporting rate was 85%. Among the 14 reporters the median reporting rate was 85% (range 36%-100%). No cases meeting the definition for an Ebola CUI were reported during the 60 days. Real-time, SMS-based, daily zero-reporting can be implemented in a rapid, simple way in a low resource country. We believe that the high compliance rates were due to the simplicity and familiarity of SMS and heightened sensitivity that resulted from STEP to the importance of zero-reporting in the midst of an Ebola epidemic in neighbouring countries. This model could be useful for rapid scale-up and implementation of alert systems in other outbreaks and public health emergencies. Published by Elsevier Ltd.

Aims. This study aimed to establish the contribution of hallucination proneness, anxiety, suggestibility, and fantasy proneness to psychotic-like experiences (PLEs) reported during brief sensory deprivation. Method. Twenty-four high and 22 low hallucination-prone participants reported on PLEs occurring during brief sensory deprivation and at baseline. State/trait anxiety, suggestibility, and fantasy proneness were also measured. Results. Both groups experienced a significant increase in PLEs in sensory deprivation. The high hallucination prone group reported more PLEs both at baseline and in sensory deprivation. They also scored significantly higher on measures of state/trait anxiety, suggestibility, and fantasy proneness, though these did not explain the effects of group or condition. Regression analysis found hallucination proneness to be the best predictor of the increase in PLEs, with state anxiety also being a significant predictor. Fantasy proneness and suggestibility were not significant predictors. Conclusion. This study suggests the increase in PLEs reported during sensory deprivation reflects a genuine aberration in perceptual experience, as opposed to increased tendency to make false reports due to suggestibility of fantasy proneness. The study provides further support for the use of sensory deprivation as a safe and effective nonpharmacological model of psychosis. PMID:25811027

Varenicline is approved as an aid to smoking cessation in adults aged > or =18 years. The goal of this study was to characterize the multiple-dose pharmacokinetics, safety, and tolerability of varenicline in adolescent smokers. This multicenter, randomized, double-blind, placebo-controlled, parallel-group study enrolled healthy 12- to 16-year-old smokers (> or =3 cigarettes daily) into high-body-weight (>55 kg) and low-body-weight (< or =55 kg) groups. Subjects were randomized to receive 14 days of treatment with a high dose of varenicline, a low dose of varenicline, or placebo. The varenicline doses in the high-body-weight group were 1 mg BID and 0.5 mg BID; the varenicline doses in the low-body-weight group were 0.5 mg BID and 0.5 mg once daily. The apparent renal clearance (CL/F) and volume of distribution (V/F) of varenicline and the effect of body weight on these parameters were estimated using nonlinear mixed-effects modeling. The high-body-weight group consisted of 35 subjects (65.7% male; 77.1% white; mean age, 15.2 years). The low-body-weight group consisted of 37 subjects (37.8% male; 48.6% white; mean age, 14.3 years). The pharmacokinetic parameters of varenicline were dose proportional over the dose range from 0.5 to 2 mg/d. The CL/F for a 70-kg adolescent was 10.4 L/h, comparable to that in a 70-kg adult. The estimated varenicline V/F was decreased in individuals of small body size, thus predicting a varenicline C(max) approximately 30% greater in low-body-weight subjects than in high-body-weight subjects. In high-body-weight subjects, steady-state varenicline exposure, as represented by the AUC(0-24), was 197.0 ng . h/mL for varenicline 1 mg BID and 95.7 ng . h/mL for varenicline 0.5 mg BID, consistent with values reported previously in adult smokers at the equivalent doses. In low-body-weight subjects, varenicline exposure was 126.3 ng . h/mL for varenicline 0.5 mg BID and 60.1 ng . h/mL for varenicline 0.5 mg once daily, values at the lower end of the range observed previously in adults at doses of 1 mg BID and 0.5 mg BID, respectively. Among high-body-weight subjects, adverse events (AEs) were reported by 57.1% of subjects in both the high- and low-dose varenicline groups and by 14.3% of subjects in the placebo group; among low-body-weight subjects, AEs were reported by 64.3%, 73.3%, and 12.5% of subjects in the high-dose varenicline, low-dose varenicline, and placebo groups, respectively. The most common AEs were nausea, headache, vomiting, and dizziness. Psychiatric AEs that were considered treatment related included abnormal dreams in 2 subjects and mild, transient anger in 1 subject. Of the AEs reported by > or =1 subject in any treatment group, > or =92% were mild in intensity. No subject discontinued the study because of an AE. Varenicline steady-state exposure in study subjects weighing >55 kg was similar to that observed previously in adults. The body-weight effect on varenicline pharmacokinetics, which resulted in higher exposure in individuals of smaller body size (< or =55 kg), was adequately offset by administration of half the varenicline dose recommended in adults. Varenicline was generally well tolerated during the 14-day treatment period. Clinical Trials Identification Number: NCT00463918.

Fifteen crocodiles were randomly divided into three groups of five animals. They represented high-infection, medium-infection and low-infection groups of 642 larvae/kg, 414 larvae/kg and 134 larvae/kg bodyweight, respectively. The parameters assessed were blood glucose, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), aspartate transaminase (AST) and alanine transaminase (ALT). The humoral immune response to Trichinella zimbabwensis infection was evaluated in all three groups by an indirect ELISA method. The results showed deviations from normal parameters of blood glucose, CPK, LDH, AST and ALT when compared with reported levels in uninfected reptiles. Contrary to studies involving mammals, hypoglycaemia was not observed in the infected groups in this study. Peak values of blood glucose were reached on post-infection (PI) Day 49, Day 42 and Day 35 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of LDH and AST were observed on PI Day 56, Day 49 and Day 42 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of CPK were observed on Day 35 PI in all three groups. Peak ALT values were reached on Day 56 in the high-infection group and on Day 28 PI in both the medium-infection and low-infection groups. No correlations between the biochemical parameters and infection intensity were observed. Peak antibody titres were reached on Day 49 PI in the medium-infection group, and on Day 42 PI in both the high-infection and low-infection groups. Infection intensity could not be correlated with the magnitude of the humoral immune response or time to sero-conversion. Results from this study were in agreement with results reported in mammals infected with other Trichinella species and showed that antibody titres could not be detected indefinitely.

Cigarette smoking is a chronic, relapsing illness that is inadequately addressed in primary care practice. To compare cessation rates among smokers who receive pharmacotherapy alone or combined with either moderate- or high-intensity disease management that includes counseling and provider feedback. Randomized clinical trial from June 2004 to December 2007. 50 rural primary care practices. 750 persons who smoke more than 10 cigarettes per day. Pharmacotherapy alone (n = 250), pharmacotherapy supplemented with up to 2 counseling calls (moderate-intensity disease management) (n = 249), or pharmacotherapy supplemented with up to 6 counseling calls (high-intensity disease management) (n = 251). Interventions were offered every 6 months for 2 years. All participants were offered free pharmacotherapy. Moderate-intensity and high-intensity disease management recipients had postcounseling progress reports faxed to their physicians. Self-reported, point-prevalence smoking abstinence at 24 months (primary outcome) and overall (0 to 24 months) analyses of smoking abstinence, utilization of pharmacotherapy, and discussions about smoking with physicians (secondary outcomes). Research assistants who were blinded to treatment assignment conducted outcome assessments. Pharmacotherapy utilization was similar across treatment groups, with 473 of 741 (63.8%), 302 of 739 (40.9%), 175 of 732 (23.9%), and 179 of 726 (24.7%) participants requesting pharmacotherapy during the first, second, third, and fourth 6-month treatment cycles, respectively. Of participants who saw a physician during any given treatment cycle, 37.5% to 59.5% reported that they had discussed smoking cessation with their physician; this did not differ across the treatment groups. Abstinence rates increased throughout the study, and overall (0 to 24 months) analyses demonstrated higher abstinence among the high-intensity disease management group than the moderate-intensity disease management group (odds ratio [OR], 1.43 [95% CI, 1.00 to 2.03]) and among the combined disease management groups than the pharmacotherapy-alone group (OR, 1.47 [CI, 1.08 to 2.00]). Self-reported abstinence at 24 months was 68 of 244 (27.9%) and 56 of 238 (23.5%) participants in the high- and moderate-intensity disease management groups, respectively (OR, 1.33 [CI, 0.88 to 2.02]), and 56 of 244 (23.0%) participants in the pharmacotherapy-alone group (OR, 1.12 [CI, 0.78 to 1.61] for combined disease management vs. pharmacotherapy alone). The effect of pharmacotherapy management cannot be separated from the provision of free pharmacotherapy, and cessation was validated in only 58% of self-reported quitters. Smokers are willing to make repeated pharmacotherapy-assisted quit attempts, leading to progressively greater smoking abstinence. Although point-prevalence abstinence did not differ at 24 months, analyses that incorporated assessments across the full 24 months of treatment suggest that higher-intensity disease management is associated with increased abstinence.

Incarcerated women report multiple vulnerabilities and, yet, are under-represented in research. This study used focus-group methodology to explore high-risk sexual behaviors, drug use, and victimization among female offenders in St. Louis. Inmates of the St. Louis Medium Security Institution (MSI) were invited to participate in one of five focus groups between May and September 2005 in preparation for an NIH/NINR HIV-prevention intervention study among female offenders in Drug Court. The focus group sample of 30 women was 70% African-American, with a mean age of 36 years. Results indicated that oral sex was the most common sex trade activity. Consistent with the literature, condom usage was described as irregular. In terms of drug use, participants reported that crack was most commonly used, with binges often lasting for several days. Regarding victimization, women frequently reported sexual abuse in childhood, and some described abusive relationships as adults. Participants also reported being beaten and raped by customers, which led to their concealing knives in purses and razors under the tongue. Consequently, perpetrated violence, including murder, was reported as protection against further violence. These findings confirm the vulnerability of this population of women who are at high risk for HIV. Effective HIV-prevention interventions are needed to assist these incarcerated women in making lifestyle changes during incarceration and sustaining them after release.

2016-04-29

The extant evidence suggests a robust positive association between expression (anger expression-out) and suppression (anger expression-in) of anger and compromised health. Nevertheless, the underlying psychobiological mechanisms which explain these relationships are not well understood. This study examined whether anger expression would predict general health, cortisol awakening response (CAR) and evening cortisol levels in a community sample of 156 healthy young adults of both genders. Participants were distributed into two groups according to their anger expression scores: high and low anger expression (HAE and LAE, respectively). Findings indicated that those with HAE had worse self-reported health (p = .02) and higher CAR than the LAE group (p = .04). Moreover, high levels of anger expression-out (p < .01) and -in (p < .01, for all) predicted a worse self-reported health in both groups. On the other hand, high anger expression-out was associated with flattened CAR but only in the HAE group (p < .01). This study reinforces the need to develop effective strategies to provide mechanisms to regulate anger expression by promoting personal growth and positive skills that enhance individuals' well-being and quality of life and, in turn, their own health.
A Test of Spielberger’s State-Trait Theory of Anger with Adolescents: Five Hypotheses

Quinn, Colleen A.; Rollock, David; Vrana, Scott R.

2014-01-01

Spielberger’s state-trait theory of anger was investigated in adolescents (n = 201, ages 10–18, 53% African American, 47% European American, 48% female) using Deffenbacher’s five hypotheses formulated to test the theory in adults. Self-reported experience, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) responses to anger provoking imagery scripts found strong support for the application of this theory to adolescents. Compared to the low trait anger (LTA) group, adolescents with high trait anger (HTA) produced increased HR, SBP and DBP, and greater self-report of anger to anger imagery (intensity hypothesis) but not greater self-report or cardiovascular reactivity to fear or joy imagery (discrimination hypothesis). The HTA group also reported greater frequency and duration of anger episodes and had longer recovery of SBP response to anger (elicitation hypothesis). The HTA group was more likely to report negative health, social, and academic outcomes (consequence hypothesis). Adolescents with high hostility reported more maladaptive coping with anger, with higher anger-in and anger-out than adolescents with low hostility (negative expression hypothesis). The data on all five hypotheses supported the notion that trait anger is firmly entrenched by the period of adolescence, with few developmental differences noted from the adult literature.

Individual differences in responsiveness to caffeine occur even within a caffeine-consuming population, but the factors that mediate differential responsiveness remain unclear. To compare caffeine's effects on performance and mood in a group of high vs moderate consumers of caffeine and to examine the potential role of subjective awareness of the effects of caffeine in mediating any differential responsiveness. Two groups of regular caffeine consumers (<200 mg/day and >200 mg/day) attended two sessions at which mood and cognitive functions were measured before and 30 min after consumption of 400-mg caffeine or placebo in a capsule. Cognitive tests included visual information processing, match-to-sample visual search (MTS) and simple and choice reaction times. Post-session questionnaires asked participants to describe any perceived effect of capsule consumption. High consumers, but not moderate consumers, demonstrated significantly faster simple and choice reaction times after caffeine relative to placebo. These effects were not attributable to obvious group differences in withdrawal or tolerance because there were no group differences in baseline mood or in reports of negative affect after caffeine. Instead, the high consumers were more likely to report experiencing positive effects of caffeine, whereas the moderate consumers were more likely to report no effect. The sensitivity of caffeine consumers to the mood- and performance-enhancing effects of caffeine is related to their levels of habitual intake. High caffeine consumers are more likely than moderate consumers to perceive broadly positive effects of caffeine, and this may contribute to their levels of use.

The aim of this study was to evaluate the association between Agent Orange exposure and self-reported diseases in Korean Vietnam veterans. A postal survey of 114 562 Vietnam veterans was conducted. The perceived exposure to Agent Orange was assessed by a 6-item questionnaire. Two proximity-based Agent Orange exposure indices were constructed using division/brigade-level and battalion/company-level unit information. Adjusted odds ratios (ORs) for age and other confounders were calculated using a logistic regression model. The prevalence of all self-reported diseases showed monotonically increasing trends as the levels of perceived self-reported exposure increased. The ORs for colon cancer (OR, 1.13), leukemia (OR, 1.56), hypertension (OR, 1.03), peripheral vasculopathy (OR, 1.07), enterocolitis (OR, 1.07), peripheral neuropathy (OR, 1.07), multiple nerve palsy (OR, 1.14), multiple sclerosis (OR, 1.24), skin diseases (OR, 1.05), psychotic diseases (OR, 1.07) and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the division/brigade-level proximity-based exposure analysis, compared to the low exposure group. The ORs for cerebral infarction (OR, 1.08), chronic bronchitis (OR, 1.05), multiple nerve palsy (OR, 1.07), multiple sclerosis (OR, 1.16), skin diseases (OR, 1.05), and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the battalion/company-level analysis. Korean Vietnam veterans with high exposure to Agent Orange experienced a higher prevalence of several self-reported chronic diseases compared to those with low exposure by proximity-based exposure assessment. The strong positive associations between perceived self-reported exposure and all self-reported diseases should be evaluated with discretion because the likelihood of reporting diseases was directly related to the perceived intensity of Agent Orange exposure.
Do later wake times and increased sleep duration of 12th graders result in more studying, higher grades, and improved SAT/ACT test scores?

Cole, James S

2016-09-01

The aim of this study was to investigate the relationship between sleep duration, wake time, and hours studying on high school grades and performance on the Scholastic Aptitude Test (SAT)/ American College Testing (ACT) college entrance exams. Data were collected from 13,071 recently graduated high school seniors who were entering college in the fall of 2014. A column proportions z test with a Bonferroni adjustment was used to analyze proportional differences. Analysis of covariance (ANCOVA) was used to examine mean group differences. Students who woke up prior to 6 a.m. and got less than 8 h of sleep (27 %) were significantly more likely to report studying 11 or more hours per week (30 %), almost double the rate compared to students who got more than 8 h of sleep and woke up the latest (16 %). Post hoc results revealed students who woke up at 7 a.m. or later reported significantly higher high school grades than all other groups (p < 0.001), with the exception of those students who woke up between 6:01 a.m. and 7:00 a.m. and got eight or more hours of sleep. The highest reported SAT/ACT scores were from the group that woke up after 7 a.m. but got less than 8 h sleep (M = 1099.5). Their scores were significantly higher than all other groups. This study provides additional evidence that increased sleep and later wake time are associated with increased high school grades. However, this study also found that students who sleep the longest also reported less studying and lower SAT/ACT scores.

Objective In adulthood, depressive mood is often comorbid with ADHD, but its role in ADHD-inattentiveness and especially relations with mind wandering remains to be elucidated. This study investigated the effects of laboratory-induced dysphoric mood on task-unrelated mind wandering and its consequences on cognitive task performance in college students with high (n = 46) or low (n = 44) ADHD-Inattention symptomatology and Hyperactivity/Impulsivity symptoms in the normal range. Methods These non-clinical high/low ADHD-Inattention symptom groups underwent negative or positive mood induction after which mind wandering frequency was measured in a sustained attention (SART), and a reading task. Effects of ruminative response style and working memory capacity on mind wandering frequency were also investigated. Results Significantly higher frequencies of self -reported mind wandering in daily life, in the SART and reading task were reported in the ADHD-Inattention symptom group, with detrimental effects on text comprehension in the reading task. Induced dysphoric mood did specifically enhance the frequency of mind wandering in the ADHD-Inattention symptom group only during the SART, and was related to their higher self-reported intrusive ruminative response styles. Working memory capacity did not differ between high/low attention groups and did not influence any of the reported effects. Conclusions These combined results suggest that in a non-clinical sample with high ADHD-inattention symptoms, dysphoric mood and a ruminative response style seem to be more important determinants of dysfunctional mind wandering than a failure in working memory capacity/executive control, and perhaps need other ways of remediation, like cognitive behavioral therapy or mindfulness training.

A comparison of two microscale laboratory reporting methods in a secondary chemistry classroom

NASA Astrophysics Data System (ADS)

Martinez, Lance Michael

This study attempted to determine if there was a difference between the laboratory achievement of students who used a modified reporting method and those who used traditional laboratory reporting. The study also determined the relationships between laboratory performance scores and the independent variables score on the Group Assessment of Logical Thinking (GALT) test, chronological age in months, gender, and ethnicity for each of the treatment groups. The study was conducted using 113 high school students who were enrolled in first-year general chemistry classes at Pueblo South High School in Colorado. The research design used was the quasi-experimental Nonequivalent Control Group Design. The statistical treatment consisted of the Multiple Regression Analysis and the Analysis of Covariance. Based on the GALT, students in the two groups were generally in the concrete and transitional stages of the Piagetian cognitive levels. The findings of the study revealed that the traditional and the modified methods of laboratory reporting did not have any effect on the laboratory performance outcome of the subjects. However, the students who used the traditional method of reporting showed a higher laboratory performance score when evaluation was conducted using the New Standards rubric recommended by the state. Multiple Regression Analysis revealed that there was a significant relationship between the criterion variable student laboratory performance outcome of individuals who employed traditional laboratory reporting methods and the composite set of predictor variables. On the contrary, there was no significant relationship between the criterion variable student laboratory performance outcome of individuals who employed modified laboratory reporting methods and the composite set of predictor variables.

Polycyclic aromatic hydrocarbons are common carcinogenic and neurotoxic urban air pollutants. Toxic exposures, including air pollution, are disproportionately high in communities of color and frequently co-occur with chronic economic deprivation. We examined whether the association between child IQ and prenatal exposure to polycyclic aromatic hydrocarbons differed between groups of children whose mothers reported high vs. low material hardship during their pregnancy and through child age 5. We tested statistical interactions between hardships and polycyclic aromatic hydrocarbons, as measured by DNA adducts in cord blood, to determine whether material hardship exacerbated the association between adducts and IQ scores. Prospective cohort. Participants were recruited from 1998 to 2006 and followed from gestation through age 7 years. Urban community (New York City) A community-based sample of 276 minority urban youth EXPOSURE MEASURE: Polycyclic aromatic hydrocarbon-DNA adducts in cord blood as an individual biomarker of prenatal polycyclic aromatic hydrocarbon exposure. Maternal material hardship self-reported prenatally and at multiple timepoints through early childhood. Child IQ at 7 years assessed using the Wechsler Intelligence Scale for Children. Significant inverse effects of high cord PAH-DNA adducts on full scale IQ, perceptual reasoning and working memory scores were observed in the groups whose mothers reported a high level of material hardship during pregnancy or recurring high hardship into the child's early years, and not in those without reported high hardship. Significant interactions were observed between high cord adducts and prenatal hardship on working memory scores (β = -8.07, 95% CI (-14.48, -1.66)) and between high cord adducts and recurrent material hardship (β = -9.82, 95% CI (-16.22, -3.42)). The findings add to other evidence that socioeconomic disadvantage can increase the adverse effects of toxic physical "stressors" like air pollutants. Observed associations between high cord adducts and reduced IQ were significant only among the group of children whose mothers reported high material hardship. These results indicate the need for a multifaceted approach to prevention. Copyright © 2015 Elsevier Inc. All rights reserved.

Admission diagnosis represents the diagnosis of an illness, injury or condition due to which a patient is referred to hospital to be admitted. Discharge diagnosis represents the main reason of illness or condition due to which a patient is admitted. The aim of this study was to analyze the agreement between admission diagnostic groups and discharge diagnostic groups of patients in the Clinical Center Kragujevac in the period from January 1, 2006 to December 31, 2013 on the basis of the hospitalization report. From the basic set of reports, 5% of random samples were singled out and they contained 20,422 reports. Out of the given number of reports, 18,173 hospitalization reports were complete and then further analyzed in the paper. Admission diagnostic groups given by the primary care doctor were compared with discharge diagnostic groups filled out by the practicing physician in the hospital ward from which a patient was discharged. The agreement of these two diagnostic groups was an indication of the high-quality performance of the primary care doctor. Agreement analysis was conducted using Cohen’s Kappa statistics. Agreement analysis showed that the values of the Kappa coefficient for the five leading admission diagnostic groups were in the range of κ = 0.61 to κ = 0.94. The values of the Kappa coefficient for the five most common discharge diagnostic groups were in the range of κ = 0.55 to κ = 0.81. Hospitalization report is a reliable individual report on inpatient care, so it could be used in determining the degree of agreement between admission diagnostic groups and discharge diagnostic groups.
Deviance as adherence to injunctive group norms: the overlooked role of social identification in deviance.

PubMed

Crane, Monique F; Platow, Michael J

2010-12-01

We currently report three studies investigating group members' expressions of dissatisfaction and discontent with the behaviour and attitudes of their in-group members. Our analysis examines the context in which group members will deviate from actual group member behaviour. We argue that highly identifying group members will challenge fellow group member behaviour when that group member behaviour is perceived to violate injunctive group norms. Further, we predicted that high identifiers would still challenge such group member behaviour even if that behaviour were conducted by a majority of group members. Thus, high identifiers were predicted to express descriptively deviant opinions when the behaviour of other members contravenes injunctive group norms. In Studies 1 and 2, group-level self-definition served as a moderator in the relationship between the expression of discontent and perceived injunctive norm violation; in Study 3, group-level self-investment served as this moderator. The findings supported our predictions. This support was particularly strong when a majority of group members violated group norms. Implications for the analysis of the relationship between social identification and deviance are discussed.
Cognitive distance, absorptive capacity and group rationality: a simulation study.

We report the results of a simulation study in which we explore the joint effect of group absorptive capacity (as the average individual rationality of the group members) and cognitive distance (as the distance between the most rational group member and the rest of the group) on the emergence of collective rationality in groups. We start from empirical results reported in the literature on group rationality as collective group level competence and use data on real-life groups of four and five to validate a mathematical model. We then use this mathematical model to predict group level scores from a variety of possible group configurations (varying both in cognitive distance and average individual rationality). Our results show that both group competence and cognitive distance are necessary conditions for emergent group rationality. Group configurations, in which the groups become more rational than the most rational group member, are groups scoring low on cognitive distance and scoring high on absorptive capacity.

The neonatal resuscitation program (NRP) has been developed to educate physicians and other health care providers about newborn resuscitation and has been shown to improve neonatal resuscitation skills. Simulation-based training is recommended as an effective modality for instructing neonatal resuscitation and both low and high-fidelity manikin simulators are used. There is limited research that has compared the effect of low and high-fidelity manikin simulators for NRP learning outcomes, and more specifically on teamwork performance and confidence. The purpose of this study was to examine the effect of using low versus high-fidelity manikin simulators in NRP instruction. A randomized posttest-only control group study design was conducted. Third year undergraduate medical students participated in NRP instruction and were assigned to an experimental group (high-fidelity manikin simulator) or control group (low-fidelity manikin simulator). Integrated skills station (megacode) performance, participant satisfaction, confidence and teamwork behaviour scores were compared between the study groups. Participants in the high-fidelity manikin simulator instructional group reported significantly higher total scores in overall satisfaction (p = 0.001) and confidence (p = 0.001). There were no significant differences in teamwork behaviour scores, as observed by two independent raters, nor differences on mandatory integrated skills station performance items at the p < 0.05 level. Medical students' reported greater satisfaction and confidence with high-fidelity manikin simulators, but did not demonstrate overall significantly improved teamwork or integrated skills station performance. Low and high-fidelity manikin simulators facilitate similar levels of objectively measured NRP outcomes for integrated skills station and teamwork performance.

In type 1 diabetes increased risk of severe hypoglycaemia is associated with high angiotensin-converting enzyme (ACE) activity. We tested in healthy humans the hypothesis that this association is explained by the reduced ability of subjects with high ACE activity to maintain normal cognitive function during hypoglycaemia. Sixteen healthy volunteers selected by either particularly high or low serum ACE activity were subjected to hypoglycaemia (plasma glucose 2.7 mmol/L). Cognitive function was assessed by choice reaction tests. Despite a similar hypoglycaemic stimulus in the two groups, only the group with high ACE activity showed significant deterioration in cognitive performance during hypoglycaemia. In the high ACE group mean reaction time (MRT) in the most complex choice reaction task was prolonged and error rate (ER) was increased in contrast to the low ACE group. The total hypoglycaemic symptom response was greater in the high ACE group than in the low ACE group (p=0.031). There were no differences in responses of counterregulatory hormones or in concentrations of substrates between the groups. Healthy humans with high ACE activity are more susceptible to cognitive dysfunction and report higher symptom scores during mild hypoglycaemia than subjects with low ACE activity.
Report of the Snowmass M6 Working Group on high intensity proton sources

DOE Office of Scientific and Technical Information (OSTI.GOV)

Weiren Chou and J. Wei

The U.S. high-energy physics program needs an intense proton source, a 1-4 MW Proton Driver (PD), by the end of this decade. This machine will serve as a stand-alone facility that will provide neutrino superbeams and other high intensity secondary beams such as kaons, muons, neutrons, and anti-protons (cf. E1 and E5 group reports) and also serve as the first stage of a neutrino factory (cf. M1 group report). It can also be a high brightness source for a VLHC. Based on present accelerator technology and project construction experience, it is both feasible and cost-effective to construct a 1-4 MWmore » Proton Driver. Two recent PD design studies have been made, one at FNAL and the other at the BNL. Both designed PD's for 1 MW proton beams at a cost of about U.S. $200M (excluding contingency and overhead) and both designs were upgradeable to 4 MW. An international collaboration between FNAL, BNL and KEK on high intensity proton facilities is addressing a number of key design issues. The superconducting (sc) RF cavities, cryogenics, and RF controls developed for the SNS can be directly adopted to save R&D efforts, cost, and schedule. PD studies are also actively being pursued at Europe and Japan.« less

Family conflict exacerbates the course of bipolar disorder (BP) among adults. However, few studies have examined family conflict among adolescents with BP, and fewer have looked at adolescent-reported and parent-reported family conflict separately. Subjects were 89 adolescents, aged 13 to 19 years, with a diagnosis of BP on the basis of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL). Subjects were divided into high-conflict and low-conflict groups using a median split on the Conflict Behavior Questionnaire (child report and parent report). The χ(2) analyses and independent samples t tests were performed for univariate analyses. Multivariable logistic regression analyses were performed on variables with P<0.2. Parent-reported and adolescent-reported Conflict Behavior Questionnaire scores were significantly correlated (r=0.50, P<0.001). High parent-reported family conflict was positively associated with recent manic symptoms, externalizing comorbidities, and dimensional scores reflecting emotional dysregulation. High adolescent-reported family conflict was positively associated with recent manic symptoms and emotional dysregulation, and negatively associated with socioeconomic status and lifetime psychiatric hospitalization. Bipolar subtype was significantly associated with high versus low family conflict. The limitations of this study included being a cross-sectional study, use of a medium-sized sample, and lack of a control group. Despite substantial agreement between adolescents and parents regarding the amount of family conflict, there were meaningful differences in the factors associated with adolescent-reported and parent-reported conflict. These findings demonstrate the importance of ascertaining family conflict from adolescents as well as from parents. Moreover, these findings can potentially inform family therapy, which is known to be effective for adolescents with BP.

Asian American adults endorse more symptoms of social anxiety (SA) on self-report measures than European Americans, but demonstrate lower prevalence rates of social anxiety disorder in epidemiological studies. These divergent results create ambiguity concerning the mental health needs of Asian Americans. The present study is the first to investigate this issue in adolescents through assessment of self-reported SA in Asian American high school students. Parent and self-ratings of impairment related to SA and self-reported mental health service use for SA were also measured. Asian American students endorsed a greater number of SA symptoms and scored in the clinical range more frequently than other ethnic groups. Also, Asian American and Latino students endorsed more school impairment related to SA than other ethnic groups. No differences in parent-reported impairment or service utilization were identified. Implications for future research and treatment for SA among Asian American adolescents are discussed. PMID:25300193

An informed consumer can compensate for several potential food safety violations or contaminations that may occur earlier in the food production chain. However, a consumer can also destroy the work of others in the chain by poor food handling practices, e.g., by storing chilled ready-to-eat foods at abusive temperatures. To target risk-reducing strategies, consumer groups with high-risk behavior should be identified. The aim of this study was to identify demographic characteristics associated with high-risk food handling practices among Norwegian consumers. More than 2,000 randomly selected Norwegian consumers were surveyed, and the results were analyzed with a risk-based grading system, awarding demerit points for self-reported food safety violations. The violations were categorized into groups, and an ordinary multiple linear regression analysis was run on the summarized demerit score for each group and for the entire survey group as a whole. Young and elderly men were identified as the least informed consumer groups with the most unsafe practices regarding food safety. Single persons reported poorer practices than those in a relationship. People with higher education reported poorer practices than those with lower or no education, and those living in the capital of Norway (Oslo) reported following more unsafe food practices than people living elsewhere in Norway. Men reported poorer food safety practices than women in all categories with two exceptions: parboiling raw vegetables before consumption and knowledge of refrigerator temperature. These findings suggest that risk-reducing measures should target men, and a strategy is needed to change their behavior and attitudes.

Two groups of consecutive patients from two different plastic surgical practice populations were evaluated to determine psychosocial differences between those who underwent immediate (n = 25) versus delayed (n = 38) breast reconstruction. Psychological assessment consisted of a standardized symptom inventory (BSI) and a specially designed self-report questionnaire investigating reactions unique to mastectomy and reconstruction. Both groups were extremely equivalent with regard to sociodemographic data, with the typical subject being a well-educated and employed Caucasian wife. Verbal reports of physical complaints revealed no significant differences between the two groups except for difficulty with arm movement, which was statistically higher for the immediate group (p = 0.006.). This difference most likely was due to the axillary dissection being performed simultaneously at the time of reconstruction. The relationship between timing of reconstruction and self-reported distress over the mastectomy experience revealed that only 25 percent of the women who underwent immediate repair reported "high distress" in recalling their mastectomy surgery compared with 60 percent of the delayed reconstruction group (p = 0.02). In reference to the two scales measuring psychological symptoms, a general trend was present, with the delayed group scoring higher (although not statistically significantly) on 9 of our 12 scales. Ninety-six percent of the immediate group and 89 percent of the delayed group reported satisfaction with results.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to analyse the longitudinal associations between (1) fundamental movement skills (FMSs) and academic performance, and (2) self-reported physical activity and academic performance through junior high school in Finland. The participants of the study were 325 Finnish students (162 girls and 163 boys), who were 13 years old at the beginning of the study at Grade 7. Students performed three FMS tests and responded to a self-reported physical activity questionnaire at Grades 7 and 8. Marks in Finnish language, mathematics and history from Grades 7, 8 and 9 were collected. Structural equation modelling with multigroup method demonstrated that in the boys' group, a correlation (0.17) appeared between FMS and academic performance measured at Grade 7. The results also indicated that FMS collected at Grade 8 were significantly but weakly (path coefficient 0.14) associated with academic performance at Grade 9 for both gender groups. Finally, the results of this study demonstrated that self-reported physical activity was not significantly related to academic performance during junior high school. The findings of this study suggest that mastery of FMS may contribute to better student achievement during junior high school.

Despite the frequent co-ocurrence of hypermobile Ehler-Danlos syndrome (hEDS) and pathological anxiety, little is known about the psychosocial and health implications of such comorbidity. Our aim was to explore the association between high levels of anxiety and psychosocial (catastrophizing, kinesiophobia, somatosensory amplification, social support and functioning), health (pain, fatigue, BMI, tobacco/alcohol use, depression, diagnosis delay, general health), and sociodemographic factors in people with hEDS. In this cross-sectional study, 80 hEDS patients were divided into two groups according to self-reported anxiety levels: low and high. Psychosocial, sociodemographic and health variables were compared between the groups. Forty-one participants reported a high level of anxiety (51.2%). No differences were found in the sociodemographic variables between high-anxious and low-anxious patients. The percentage of participants with severe fatigue and high depressive symptomatology was significantly higher in the high-anxious group (80.5 vs 56.4; 26.8 vs 12.8%, respectively). High-anxious hEDS patients also showed significantly higher levels of pain catastrophizing, somatosensory amplification as well as a poorer social functioning and general health. Multivariate analyses showed that somatosensory amplification, pain catastrophizing and poor social functioning are variables that increase the probability of belonging to the high-anxious group. Despite limitations, this first study comparing high-anxious versus low-anxious hEDS patients with respect to health aspects, highlight the importance of considering the psychosocial factors (many susceptible to modification), to improve the adjustment to this chronic condition and provide support to those affected through a biopsychosocial approach.

The major feature that separates stereotactic radiation therapy (cranial SRT) and stereotactic body radiation therapy (SBRT) from conventional radiation treatment is the delivery of large doses in a few fractions which results in a high biological effective dose (BED). In order to minimize the normal tissue toxicity, quality assurance of the conformation of high doses to the target and rapid fall off doses away from the target is critical. The practice of SRT and SBRT therefore requires a high-level of confidence in the accuracy of the entire treatment delivery process. In SRT and SBRT confidence in this accuracy is accomplished by the integration of modern imaging, simulation, treatment planning and delivery technologies into all phases of the treatment process; from treatment simulation and planning and continuing throughout beam delivery. In this report some of the findings of Task group 101 of the AAPM will be presented which outlines the best-practice guidelines for SBRT. The task group report includes a review of the literature to identify reported clinical findings and expected outcomes for this treatment modality. Information in this task group is provided for establishing an SBRT program, including protocols, equipment, resources, and QA procedures.

The synthesis of highly efficient two-photon uncaging groups and their potential use in functional conjugated polymers for post-polymerization modification are reported. Careful structural design of the employed nitrophenethyl caging groups allows to efficiently induce bond scission by a two-photon process through a combination of exceptionally high two-photon absorption cross-sections and high reaction quantum yields. Furthermore, π-conjugated polyfluorenes are functionalized with these photocleavable side groups and it is possible to alter their emission properties and solubility behavior by simple light irradiation. Cleavage of side groups leads to a turn-on of the fluorescence while solubility of the π-conjugated materials is drastically reduced. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The purpose of this randomized controlled study was to examine the efficacy of a brief, web-based personalized feedback intervention (the eCHECKUP TO GO) on alcohol use and alcohol-related consequences among high school seniors. Participants (n = 221) were high school seniors randomized by class period to either a brief, web-based personalized feedback intervention (the eCHECKUP TO GO) or an assessment-only control group. Participants completed online surveys at baseline and at a 6-week follow-up. Students participating in the eCHECKUP TO GO intervention reported a significant reduction in weekly drinking quantity, peak drinking quantity, and frequency of drinking to intoxication relative to those in the control group. Intervention effects were moderated by high-risk status (one or more episodes of heavy episodic drinking in the past 2 weeks reported at baseline) such that intervention effects were significant for high-risk students only. Results for alcohol-related consequences were not significant. Providing a brief, web-based personalized feedback intervention in the school setting is a promising approach for reducing problem alcohol use among high school seniors who report recent heavy episodic drinking.
When somatization is not the only thing you suffer from: Examining comorbid syndromes using latent profile analysis, parenting practices and adolescent functioning.

Understanding somatization presents a challenge to clinicians because it is often associated with other syndromes. We addressed somatization's comorbidity with other internalizing syndromes (anxiety, depression, withdrawal) using latent profile analysis. A representative sample of 3496 Israeli middle and high-school youths reported their internalizing symptoms, perceived parenting practices, psychosocial functioning, and health behaviors. Four profiles, similar across age and gender, were identified: overall-low (65.4%), moderately-high anxiety/depression/withdrawal (24.4%), high somatization (4.8%), and overall-high (5.4%). MANOVAs and follow-up ANOVAs revealed that for the most part the overall-high profile evinced the worst parenting, psychosocial functioning, and health behaviors (smoking and drinking), while the overall-low group evinced the best. For most variables the high somatization and moderately high profiles displayed midway results. However, the moderately-high profile reported higher levels of harsh parenting than the high somatization profile. The high somatization profile reported similar or higher levels of smoking, risk taking, vandalism, and rule violation than the overall-high group. High somatization, either alone or alongside anxiety, depression, and withdrawal, was associated with disruptive and risk-taking behaviors. This link might reflect problems in emotion and anger regulation and become stronger in adolescence because of dysregulation processes characterizing this period. Implications for practice are discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to investigate trajectories of sleep quality and associations with mood in the perinatal period. Although it is commonly accepted that subjective sleep quality declines during pregnancy and the transition to parenthood, some women may follow qualitatively distinct trajectories. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Data were collected from 293 women at four time points: during early pregnancy, at Time 1 (T1; < 22 w gestational age [GA]; late pregnancy, at Time 2 (T2; 32 w GA); during the postnatal period at Time 3 (T3; 3 mo postpartum); and Time 4 (T4; 6 mo postpartum). A group-based semiparametric mixture model was used to estimate patterns of sleep quality throughout the perinatal period. Four trajectory groups were identified, including patterns defined by high sleep quality throughout (21.5%), mild decrease in sleep quality (59.5%), significant decrease in sleep quality (12.3%) and a group with poor sleep quality throughout (6.7%). Women who had the worst sleep quality at Time 1 and those who experienced significant increases in sleep problems throughout pregnancy were also the groups who reported the highest levels of anxiety and depressive symptoms in early pregnancy and the lowest levels of social support. After controlling for covariates, the groups with worst subjective sleep quality during pregnancy were also the most likely to experience high symptoms of depression in the postpartum period. Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period. © 2015 Associated Professional Sleep Societies, LLC.

In 1984 the Venezuelan Work Groups in Mycology (VWGM) were created introducing an innovative approach to the study of the mycoses in Venezuela. To study the occurrence of the mycoses in Venezuela. Review the reported cases of mycoses by the newsletter Boletín Informativo Las Micosis en Venezuela (VWGM) from 1984 to 2010. The data collected showed 36,968 reported cases of superficial mycoses, 1,989 of deep systemic cases, and 822 of localized mycoses. Pityriasis dermatophytosis was the most common superficial infection, and paracoccidioidomycosis and histoplasmosis the most frequent deep systemic infection. Chromoblastomycosis was the most frequently diagnosed subcutaneous infection. The data provided showed the distribution by geographical area for each of the fungal infections studied, which may help to establish the endemic areas. Superficial mycosis is a public health problem due to its high morbidity and is probably responsible for some of the outbreaks in high-risk groups. Paracoccidioidomycosis and histoplasmosis were reported more often, which agrees with earlier reports prior to the formation of the VWGM. Cases of sporotrichosis and chromoblastomycosis in Venezuela can be considered unique due to the high number of cases. This study highlights the contribution of the VWGM to the behavior of the mycoses in Venezuela, its incidence, prevalence, and the recognition of these infections as a problem of public health importance. The VWGM should keep working in this endeavor, not only reporting new cases, but also unifying the clinical and epidemiological criteria, in order to properly monitor the evolving epidemiological changes reported in these types of infections.

The performing arts style of cirque has grown in popularity, with high-school participants increasingly practicing this style. Still, little research has examined the injury reporting rates and patterns in this population. Our study aimed to compare injury reporting rates and injury concealment patterns between high-school cirque performers and a peer-group of basketball players. Fifty participants (30 cirque, 20 basketball) completed a 12-item injury history and concealment instrument with chi-squared analyses and Fisher's exact tests comparing groups (p = 0.05). While no group differences (p = 0.36) existed in injuries reported, basketball players were more likely (p = 0.01) to miss participation due to injury than cirque performers. No significant difference existed between participants regarding which healthcare provider they reported to first (p = 0.27), but basketball players reported their injuries to the athletic trainer at higher rates (50%) than cirque performers (20%). A nonsignificant trend (p = 0.08) was noted in promptness to report injury, with more cirque performers (13%) concealing their injuries than basketball players (5%). Several reasons were noted for concealment of injury, with the most common being the belief that the injury would "go away" on its own. Knee injuries were most common in basketball players (23.7%) and back and knee injuries (10.5% each) in cirque performers. Despite similar injury rates, cirque participants concealed injuries more than peer-basketball players. Reasons may include losing performance roles, unfamiliarity and low trust with healthcare providers, ignorance about initially minor-looking injuries, and higher pain tolerance thresholds. Education and communication are essential to allow performing artists to seek healthcare support. Research is needed to appropriately understand and meet the needs of this underserved performing artist population.

This study examined the relationship of three social support and three organizational variables to two well-being and two group appraisal variables among 144 members of Compassionate Friends, Multiple Sclerosis, and Overeaters Anonymous self-help groups. An anonymous questionnaire was the major research instrument. Receiving social support was not significantly related to depression or anxiety but was positively related to perceived group benefits and group satisfaction. Providing social support and friendship were each positively related to one well-being and one group appraisal variable. Bidirectional supporters (i.e., individuals high on both receiving and providing support) reported more favorable well-being and group appraisal than Receivers, Providers, and Low Supporters. At the group level of analysis (n = 15 groups), groups with higher levels of role differentiation, greater order and organization, and in which leaders were perceived as more capable contained members who reported more positive well-being and group appraisal. The implications for future research and professional consultation to self-help groups are discussed.

Socioeconomic and demographic factors can affect the impact of telehealth education programs that use interactive compressed video technology. This study assessed program satisfaction among participants in the University of Arkansas for Medical Sciences' School Telehealth Education Program delivered by interactive compressed video. Variables in the one-group posttest study were age, gender, ethnicity, education, community size, and program topics for years 1997-1999. The convenience sample included 3,319 participants in junior high and high schools. The School Telehealth Education Program provided information about health risks, disease prevention, health promotion, personal growth, and health sciences. Adolescents reported medium to high levels of satisfaction regarding program interest and quality. Significantly higher satisfaction was expressed for programs on muscular dystrophy, anatomy of the heart, and tobacco addiction (p < 0.001 to p = 0.003). Females, African Americans, and junior high school students reported significantly greater satisfaction (p < 0.001 to p = 0.005). High school students reported significantly greater satisfaction than junior high school students regarding the interactive video equipment (p = 0.011). White females (p = 0.025) and African American males (p = 0.004) in smaller, rural communities reported higher satisfaction than White males. The School Telehealth Education Program, delivered by interactive compressed video, promoted program satisfaction among rural and minority populations and among junior high and high school students. Effective program methods included an emphasis on participants' learning needs, increasing access in rural areas among ethnic groups, speaker communication, and clarity of the program presentation.

The main purpose of this study was to report age-based subjective age-of-acquisition (AoA) norms for 600 Turkish words. A total of 115 children, 100 young adults, 115 middle-aged adults, and 127 older adults provided AoA estimates for 600 words on a 7-point scale. The intraclass correlations suggested high reliability, and the AoA estimates were highly correlated across the four age groups. Children gave earlier AoA estimates than the three adult groups; this was true for high-frequency as well as low-frequency words. In addition to the means and standard deviations of the AoA estimates, we report word frequency, concreteness, and imageability ratings, as well as word length measures (numbers of syllables and letters), for the 600 words as supplemental materials. The present ratings represent a potentially useful database for researchers working on lexical processing as well as other aspects of cognitive processing, such as autobiographical memory.

Objective The present study examined the role of negative emotions on driving performance in relation to ADHD, by comparing young adults scoring high on measures of ADHD (n = 20) with a control group (n = 22). Method The authors used cardiorespiratory physiological measures, simulated driving behavior, and self-report to examine how participants with high and low ADHD symptoms responded to frustration and to determine how frustration affected simulated driving performance. Results Groups did not differ in operational driving skills, but participants with high ADHD symptoms reported more frustration and exhibited more impairment at the tactical level of driving performance than the controls. There was significant suppression of respiratory sinus arrhythmia from resting baseline during tasks, but it did not differ between groups during driving. Conclusion This article proposes that remedial driver training for ADHD populations should focus more on the control of negative emotions rather than on attention or fundamental driving skills.

Up to now, all tested Ebola virus vaccines have been based on the virus strain from the Zaire outbreak in 1976. We aimed to assess the safety and immunogenicity of a novel recombinant adenovirus type-5 vector-based Ebola vaccine expressing the glycoprotein of the 2014 epidemic strain. We did this randomised, double-blind, placebo-controlled, phase 1 clinical trial at one site in Taizhou County, Jiangsu Province, China. Healthy adults (aged 18-60 years) were sequentially enrolled and randomly assigned (2:1), by computer-generated block randomisation (block size of six), to receive placebo, low-dose adenovirus type-5 vector-based Ebola vaccine, or high-dose vaccine. Randomisation was pre-stratified by dose group. All participants, investigators, and laboratory staff were masked to treatment allocation. The primary safety endpoint was occurrence of solicited adverse reactions within 7 days of vaccination. The primary immunogenicity endpoints were glycoprotein-specific antibody titres and T-cell responses at day 28 after the vaccination. Analysis was by intention to treat. The study is registered with ClinicalTrials.gov, number NCT02326194. Between Dec 28, 2014, and Jan 9, 2015, 120 participants were enrolled and randomly assigned to receive placebo (n=40), low-dose vaccine (n=40), or high-dose vaccine. Participants were followed up for 28 days. Overall, 82 (68%) participants reported at least one solicited adverse reaction within 7 days of vaccination (n=19 in the placebo group vs n=27 in the low-dose group vs n=36 in the high-dose group; p=0·0002). The most common reaction was mild pain at the injection site, which was reported in eight (20%) participants in the placebo group, 14 (35%) participants in the low-dose group, and 29 (73%) participants in the high-dose vaccine group (p<0·0001). We recorded no statistical differences in other adverse reactions and laboratory tests across groups. Glycoprotein-specific antibody titres were significantly increased in participants in the low-dose and high-dose vaccine groups at both day 14 (geometric mean titre 421·4 [95% CI 249·7-711·3] and 820·5 [598·9-1124·0], respectively; p<0·0001) and day 28 (682·7 [424·3-1098·5] and 1305·7 [970·1-1757·2], respectively; p<0·0001). T-cell responses peaked at day 14 at a median of 465·0 spot-forming cells (IQR 180·0-1202·5) in participants in the low-dose group and 765·0 cells (400·0-1460·0) in those in the high-dose group. 21 (18%) participants had mild fever (n=9 in the placebo group, n=6 in the low-dose group, and n=6 in the high-dose group). No serious adverse events were recorded. Our findings show that the high-dose vaccine is safe and robustly immunogenic. One shot of the high-dose vaccine could mount glycoprotein-specific humoral and T-cell response against Ebola virus in 14 days.

Chlorella (Parachlorella beijerinckii) powder is reported to show a preventive effect against metabolic syndromes such as arteriosclerosis, hyperlipidemia, and hypertension. Approximately 60% of the chlorella content is protein. In order to understand the role of chlorella protein, we prepared a chlorella protein hydrolysate (CPH) by protease treatment. Male C57BL/6 mice were divided into three groups: a normal diet group, high-fat diet (HFD) group, and high-fat diet supplemented with CPH (HFD+CPH) group. The CPH administration improved glucose intolerance, insulin sensitivity, and adipose tissue hypertrophy in the high-fat diet-fed mice. In addition, the HFD+CPH group had significantly decreased liver total cholesterol and triglyceride levels compared with those in the HFD group. Furthermore, the HFD+CPH group had a decreased level of monocyte chemotactic protein-1 (MCP-1) in serum and a lower MCP-1 mRNA expression level in adipose tissue compared with the HFD group. The present study suggests that chlorella protein hydrolysate can prevent a high-fat diet-induced glucose disorder and fatty liver by inhibiting adipocyte hypertrophy and reducing the MCP-1 protein and gene expression.

Adolescents from areas of high deprivation are often assumed to have low aspirations for the future. However, recent research has suggested otherwise and there have been calls for more substantial investigation into the relationship between poverty and aspiration. This article reports levels and variation in aspiration from 1214 adolescents (49.5 % male; 50.5 % female) living in areas of high deprivation across 20 London boroughs. A strength of this study is our large and diverse population of low socio-economic status (SES) adolescents, comprising of white British (22 %), black African (21 %), black Caribbean (9 %), Indian/Pakistani/Bangladeshi/Other Asian (24 %), mixed ethnicity (9 %), and 15 % defining themselves as Other. Our measures indicated a high group level of reported aspiration with notable variations. Females reported higher educational (but not occupational) aspirations than males; white British students reported lower educational and occupational aspirations than other ethnic groups; and black African children reported the highest educational aspirations. Perceived parental support for education had the largest positive association with aspirations. In contrast to previous findings from studies carried out in the United States, aspirations were found to be negatively associated with perceptions of school and school peer environment. These measures explored feelings of safety, happiness and belonging within the school environment and school peer group. We discuss possible explanations for this unexpected finding within our population of adolescents from UK state schools and how it might affect future policy interventions. This study makes an important contribution to the literature on adolescent aspirations because of the unique nature of the data sample and the multiple domains of functioning and aspiration measured.

There is a tendency for students from different nationalities to remain within groups of similar cultural backgrounds. The study reported here used group project work to encourage integration and cooperative learning between Australian students and Asian (Southeast Asian) international students in the second year of a veterinary science program. The group project involved an oral presentation during a second-year course (Structure and Function), with group formation engineered to include very high, high, moderate, and low achievers (based on previous grades). One Asian student and three Australian students were placed in each group. Student perceptions of group dynamics were analyzed through a self-report survey completed at the end of the presentations and through group student interviews. Results from the survey were analyzed by chi-square to compare the responses between Asian and Australian students, with statistical significance accepted at p < 0.05. There were too few Asian students for statistical analysis from a single year; therefore, the results from two successive years, 2004 (N = 104; 26% Asian) and 2005 (N = 105; 20% Asian), were analyzed. All participating students indicated in the interviews that the project was worthwhile and a good learning experience. Asian students expressed a greater preference for working in a group than for working alone (p = 0.001) and reported more frequently than Australian students that teamwork produces better results (p = 0.01). Australian students were more likely than Asian students to voice their opinion in a team setting (p = 0.001), while Asian students were more likely to depend on the lecturer for directions (p = 0.001). The results also showed that group project work appeared to create an environment that supported learning and was a successful strategy to achieve acceptance of cultural differences.

The current study provides the first replication trial of Bounce Back, a school-based intervention for elementary students exposed to trauma, in a different school district and geographical area. Participants in this study were 52 1st through 4th graders (Mage = 7.76 years; 65% male) who were predominately Latino (82%). Schools were randomly assigned to immediate treatment or waitlist control. Differential treatment effects (Time × Group Interaction) were found for child-reported posttraumatic stress disorder (PTSD) and parent-reported child coping, indicating that the immediate treatment group showed greater reductions in PTSD and improvements in coping compared with the delayed group. Differential treatment effects were not significant for depression or anxiety. Significant maintenance effects were found for both child-reported PTSD and depression as well as parent-reported PTSD and coping for the immediate treatment group at follow-up. Significant treatment effects were also found in the delayed treatment group, showing reductions in child-reported PTSD, depression, and anxiety as well as parent-reported depression and coping upon receiving treatment. In conclusion, the current study suggests that Bounce Back is an effective intervention for reducing PTSD symptoms and improving coping skills, even among a sample experiencing high levels of trauma and other ongoing stressors.

Diagnostic assays with the sensitivity required to improve cancer therapeutics depend on the development of new signal amplification technologies. Herein, we report the development and application of a novel amplification system which utilizes latent quinone methides (QMs) activated by alkaline phosphatase (AP) for signal amplification in solid-phase immunohistochemical (IHC) assays. Phosphate-protected QM precursor substrates were prepared and conjugated to either biotin or a fluorophore through an amine-functionalized linker group. Upon reaction with AP, the phosphate group is cleaved, followed by elimination of the leaving group and formation of the highly reactive and short-lived QM. The QMs either react with tissue nucleophiles in close proximity to their site of generation, or are quenched by nucleophiles in the reaction media. The reporter molecules that covalently bind to the tissue were then detected visually by fluorescence microscopy in the case of fluorophore reporters, or brightfield microscopy using diaminobenzidine (DAB) in the case of biotin reporters. With multiple reporters deposited per enzyme, significant signal amplification was observed utilizing QM precursor substrates containing either benzyl difluoro or benzyl monofluoro leaving group functionalities. However, the benzyl monofluoro leaving group gave superior results with respect to both signal intensity and discretion, the latter of which was found to be imperative for use in diagnostic IHC assays.

2007-02-01

Children with Autism Spectrum Disorders (ASD) and children with Obsessive Compulsive Disorder (OCD) were compared on a range of repetitive behaviours. Parents reported similar levels of sameness behaviour and repetitive movements in the clinical groups, although children with OCD engaged in more repetitive behaviour focussed around routines and rituals. Children with OCD reported more compulsions and obsessions than children with ASD; both groups reported more compulsions and obsessions than a typically developing comparison group. Types of compulsions and obsessions tended to be less sophisticated in children with ASD than those with OCD. Sameness behaviour was more prevalent in younger children with OCD, but for children with ASD, age was not significantly related to sameness behaviour, repetitive movements, compulsions, or obsessions.

Low income has been established as a risk factor for poorer outcomes in youth with type 1 diabetes; however, the effect of moderate income has not been studied. The purpose of this secondary analysis of baseline data from a multi-site study was to compare glycemic control, self-management, and psychosocial outcomes [depression, stress, and quality of life (QOL)] at different income levels in adolescents with type 1 diabetes. Youth (n = 320, mean age = 12.3 + 1.1, 55% female, 64% white, mean A1C = 8.3 ± 1.4) completed established self-management and psychosocial measures. A1C levels were collected from medical records. Caregivers reported annual family income, categorized as high (>$80K), moderate ($40-80K), or low (<$40K). Youth from high-income families had significantly lower A1C (mean = 7.9 ± 1.2) than those from the moderate-income group (8.6 ± 1.7, p < 0.001) or the low-income group (mean A1C = 8.6 ± 1.5, p = 0.003). Youth from the high-income group reported significantly better diabetes problem solving and more self-management goals than those from the moderate- or low-income groups (both p < 0.01). Youth from the high-income group also reported significantly fewer symptoms of depression, lower levels of perceived stress, and better QOL than those in the moderate or low-income groups (all p < 0.05). Multivariate linear regression models were used to test psychological and behavioral predictors of A1C and QOL. Parents' education status (p < 0.05) and self-management activities (p < 0.01) were significant predictors of hemoglobin A1c, while income (p < 0.01) and self-management activities (p < 0.05) were significant predictors of QOL. © 2014 John Wiley & Sons A/S.

The performance of medical groups is receiving increased attention. Relatively little conceptual or empirical work exists that examines the various dimensions of medical group performance. Using a national database of 693 medical groups, this article develops a scorecard approach to assessing group performance and presents a theory-driven framework for differentiating between high-performing versus low-performing medical groups. The clinical quality of care, financial performance, and organizational learning capability of medical groups are assessed in relation to environmental forces, resource acquisition and resource deployment factors, and a quality-centered culture. Findings support the utility of the performance scorecard approach and identification of a number of key factors differentiating high-performing from low-performing groups including, in particular, the importance of a quality-centered culture and the requirement of outside reporting from third party organizations. The findings hold a number of important implications for policy and practice, and the framework presented provides a foundation for future research.

OBJECTIVE Tranexamic acid (TXA), a synthetic antifibrinolytic drug, has been reported to reduce blood loss in orthopedic surgery, but there have been few reports of its use in spine surgery. Previous studies included limitations in terms of different TXA dose regimens, different levels and numbers of fused segments, and different surgical techniques. Therefore, the authors decided to strictly limit TXA dose regimens, surgical techniques, and fused segments in this study. There have been no reports of using TXA for prevention of intraoperative and postoperative blood loss in posterior lumbar interbody fusion (PLIF). The purpose of the study was to evaluate the efficacy of high-dose TXA in reducing blood loss and its safety during single-level PLIF. METHODS The study was a nonrandomized, case-controlled trial. Sixty consecutive patients underwent single-level PLIF at a single institution. The first 30 patients did not receive TXA. The next 30 patients received 2000 mg of intravenous TXA 15 minutes before the skin incision was performed and received the same dose again 16 hours after the surgery. Intra- and postoperative blood loss was compared between the groups. RESULTS There were no statistically significant differences in preoperative parameters of age, sex, body mass index, preoperative diagnosis, or operating time. The TXA group experienced significantly less intraoperative blood loss (mean 253 ml) compared with the control group (mean 415 ml; p < 0.01). The TXA group also had significantly less postoperative blood loss over 40 hours (mean 321 ml) compared with the control group (mean 668 ml; p < 0.01). Total blood loss in the TXA group (mean 574 ml) was significantly lower than in the control group (mean 1080 ml; p < 0.01). From 2 hours to 40 hours, postoperative blood loss in the TXA group was consistently significantly lower. There were no perioperative complications, including thromboembolic events. CONCLUSIONS High-dose TXA significantly reduced both intra- and postoperative blood loss without causing any complications during or after single-level PLIF.

Web-based, computer-tailored nutrition education interventions can be effective in modifying self-reported dietary behaviors. Traditional computer-tailored programs primarily targeted individual cognitions (knowledge, awareness, attitude, self-efficacy). Tailoring on additional variables such as self-regulation processes and environmental-level factors (the home food environment arrangement and perception of availability and prices of healthy food products in supermarkets) may improve efficacy and effect sizes (ES) of Web-based computer-tailored nutrition education interventions. This study evaluated the short- and medium-term efficacy and educational differences in efficacy of a cognitive and environmental feedback version of a Web-based computer-tailored nutrition education intervention on self-reported fruit, vegetable, high-energy snack, and saturated fat intake compared to generic nutrition information in the total sample and among participants who did not comply with dietary guidelines (the risk groups). A randomized controlled trial was conducted with a basic (tailored intervention targeting individual cognition and self-regulation processes; n=456), plus (basic intervention additionally targeting environmental-level factors; n=459), and control (generic nutrition information; n=434) group. Participants were recruited from the general population and randomly assigned to a study group. Self-reported fruit, vegetable, high-energy snack, and saturated fat intake were assessed at baseline and at 1- (T1) and 4-months (T2) postintervention using online questionnaires. Linear mixed model analyses examined group differences in change over time. Educational differences were examined with group×time×education interaction terms. In the total sample, the basic (T1: ES=-0.30; T2: ES=-0.18) and plus intervention groups (T1: ES=-0.29; T2: ES=-0.27) had larger decreases in high-energy snack intake than the control group. The basic version resulted in a larger decrease in saturated fat intake than the control intervention (T1: ES=-0.19; T2: ES=-0.17). In the risk groups, the basic version caused larger decreases in fat (T1: ES=-0.28; T2: ES=-0.28) and high-energy snack intake (T1: ES=-0.34; T2: ES=-0.20) than the control intervention. The plus version resulted in a larger increase in fruit (T1: ES=0.25; T2: ES=0.37) and a larger decrease in high-energy snack intake (T1: ES=-0.38; T2: ES=-0.32) than the control intervention. For high-energy snack intake, educational differences were found. Stratified analyses showed that the plus version was most effective for high-educated participants. Both intervention versions were more effective in improving some of the self-reported dietary behaviors than generic nutrition information, especially in the risk groups, among both higher- and lower-educated participants. For fruit intake, only the plus version was more effective than providing generic nutrition information. Although feasible, incorporating environmental-level information is time-consuming. Therefore, the basic version may be more feasible for further implementation, although inclusion of feedback on the arrangement of the home food environment and on availability and prices may be considered for fruit and, for high-educated people, for high-energy snack intake.

The high rate of violence in the healthcare sector supports the need for greater surveillance efforts. The purpose of this study was to use a province-wide workplace incident reporting system to calculate rates and identify risk factors for violence in the British Columbia healthcare industry by occupational groups, including nursing. Data were extracted for a 1-year period (2004-2005) from the Workplace Health Indicator Tracking and Evaluation database for all employee reports of violence incidents for four of the six British Columbia health authorities. Risk factors for violence were identified through comparisons of incident rates (number of incidents/100,000 worked hours) by work characteristics, including nursing occupations and work units, and by regression models adjusted for demographic factors. Across health authorities, three groups at particularly high risk for violence were identified: very small healthcare facilities [rate ratios (RR) = 6.58, 95% CI =3.49, 12.41], the care aide occupation (RR = 10.05, 95% CI = 6.72, 15.05), and paediatric departments in acute care hospitals (RR = 2.22, 95% CI = 1.05, 4.67). The three high-risk groups warrant targeted prevention or intervention efforts be implemented. The identification of high-risk groups supports the importance of a province-wide surveillance system for public health planning.

Objective To identify ethnic differences in HIV risk behaviors among cocaine using women receiving methadone maintenance for opioid dependence, and to evaluate the efficacy of contingency management (CM) for cocaine use disorders in reducing HIV risk behaviors. Methods African American (N=47), Hispanic (N=47), and White women (N = 29) were randomized to standard methadone treatment or standard methadone treatment plus a CM intervention. They completed the HIV Risk Behavior Scale (HRBS) indicating frequency of drug use and sexual behaviors across the lifetime, in the month before baseline, and in the 3 months following clinical trial participation. Ethnic group differences and the effect of CM on change in HIV risk behaviors between baseline and follow-up were evaluated. Results White women reported significantly higher lifetime rates of risky drug use and sexual behaviors on the HRBS than African American women; neither group differed significantly from Hispanic women. No ethnic group differences in HIV risk behaviors were identified in the month prior to baseline. At follow-up, African American women reported fewer high-risk drug use behaviors than White or Hispanic women, and Hispanic women reported more high-risk sexual behaviors than White or African American women. CM was associated with reduction in high-risk drug use behaviors regardless of ethnicity, but did not affect high-risk sexual behaviors. Conclusions White women receiving methadone maintenance engage in more lifetime HIV risk behaviors than African American women. CM for cocaine use reduces risky drug use behaviors, but certain ethnic groups may benefit from additional targeted HIV prevention efforts. PMID:18684571

Carboxylic acids (CAs) are one of the most ubiquitous and important chemical feedstocks available from biorenewable resources, CO 2 , and the petrochemical industry. Unfortunately, chemoselective catalytic transformations of CH n CO 2 H (n = 1-3) groups into other functionalities remain a significant challenge. Herein, we report rhenium V complexes as extremely effective precatalysts for this purpose. Compared to previously reported heterogeneous and homogeneous catalysts derived from high- or low-valent metals, the present method involves a α-C-H bond functionalization, a hydrogenation, and a hydrogenolysis, which affords functionalized alcohols with a wide substrate scope and high chemoselectivity under relatively mild reaction conditions. The results represent an important step toward a paradigm shift from 'low-valent' to 'high-valent' metal complexes by exploring a new portfolio of selective functional group transformations of highly oxygenated organic substrates, as well as toward the exploitation of CAs as a valuable biorenewable feedstock.

Cue-reactivity to chocolate images was assessed using self-report and physiological measures. From a pre-screening sample of 454, young women were selected and assigned to high and low chocolate craving groups (N = 36/group). The experimental procedure consisted in the elicitation and measurement of the cardiac defense and startle reflexes while viewing chocolate and standard affective images selected from the International Affective Picture System. In response to chocolate images, high cravers reported more pleasure and arousal but less control than low cravers. In high cravers, viewing chocolate images inhibited the cardiac defense but potentiated the startle reflex, as compared to low cravers. The results confirmed at the physiological level that the motivational state that underlies the experience of chocolate craving include both appetitive (inhibition of the defense reflex) and aversive (potentiation of the startle response) components. The findings supported a motivational conflict theory of chocolate craving.

The study objective was to explore the effect of music as an adjunct to local anesthesia on pain and anxiety during first-trimester surgical abortion. Secondary outcomes included patient satisfaction and coping. We conducted a randomized controlled pilot study of 26 women comparing music and local anesthesia to local anesthesia alone. We assessed pain, anxiety and coping with 11-point verbal numerical scales. Patient satisfaction was measured via a 4-point Likert scale. In the music group, we noted a trend toward a faster decline in anxiety postprocedure (p=.065). The music group reported better coping than the control group (mean±S.D., 8.5±2.3 and 6.2±2.8, respectively; p<.05). Both groups reported similarly high satisfaction scores. There were no group differences in pain. Music as an adjunct to local anesthesia during surgical abortion is associated with a trend toward less anxiety postprocedure and better coping while maintaining high patient satisfaction. Music does not appear to affect abortion pain. Copyright © 2012 Elsevier Inc. All rights reserved.
Brief report: assessment of the social-emotional profile in children with autism spectrum disorders using a novel comic strip task.

Sivaratnam, Carmel S; Cornish, Kim; Gray, Kylie M; Howlin, Patricia; Rinehart, Nicole J

2012-11-01

This study investigated whether the novel Comic Strip Task (CST) could be used to detect Theory-of-Mind impairments (ToM) in 4- to 8-year-old children with high functioning Autism Spectrum Disorders (ASD). Twelve children with either high-functioning autism or Asperger's Disorder and 12 typically-developing children completed the 21-item measure. The overall CST demonstrated moderate internal consistency but the Belief-understanding subscale was excluded from the test due to poor reliability. As predicted, the ASD group performed significantly more poorly than controls on the overall 2-subscale CST and on the intention-understanding subscale. No group differences were found in emotion-understanding subscale performance. Controlling for age, verbal ability was positively correlated with overall CST performance across groups. CST performance in the ASD group positively correlated with parent-reports of communication difficulties. Despite some limitations with the belief-understanding subscale, the CST has promising psychometric features warranting further development of this measure.

Research on mindful parenting, an extension of mindfulness to the interpersonal domain of parent-child relationships, has been limited by its reliance on self-report assessment. The current study is the first to examine whether observational indices of parent-youth interactions differentiate between high and low levels of self-reported mindful parenting. The Iowa Family Interaction Rating Scales (IFIRS) were used to code interactions between mothers and their 7th grade youth. Mothers drawn from the top and bottom quartiles (n = 375) of a larger distribution of self-reported interpersonal mindfulness in parenting (N = 804) represented clearly defined high and low mindful parenting groups. Discriminant function analysis (DFA) was used to analyze how well six composite IFIRS observational rating variables (e.g., parental warmth, consistent discipline) discriminated between high and low self-reports of mindful parenting. DFA results were cross-validated, with statistically significant canonical correlations found for both subsamples (p < .05). Subsequent independent samples t-tests revealed that group means were significantly different on all six IFIRS composite ratings. Confirmation of the relations between self-report mindful parenting and the observational ratings was also provided through hierarchical regression analyses conducted with a continuous predictor of mindful parenting using the full sample. Thus, the present study provides preliminary evidence for a link between self-reported mindful parenting and observed interactions between parents and youth. PMID:25844494

This research reports a study of student worksheet based on discovery learning on Mechanical Behavior of Materials topics under Android application (Android worksheet application) for vocational high school. The samples are Architecture class X students of SMKN 4 (a public vocational high school) in Tangerang Selatan City, province of Banten, Indonesia. We made 3 groups based on Intellectual Quotient (IQ). They are average IQ group, middle IQ group and high IQ group. The method of research is used as a quasi-experimental design with nonequivalent control group design. The technique of sampling is purposive sampling. Instruments used in this research are test instruments and non-test instruments. The test instruments are IQ test and test of student's achievement. For the test of student's achievement (pretest and posttest) we provide 25 multiple choice problems. The non-test instruments are questionnaire responses by the students and the teacher. Without IQ categorized, the result showed that there is an effect of Android worksheet application on student's achievement based on cognitive aspects of Revised Bloom's Taxonomy. However, from the IQ groups point of view, only the middle IQ group and the high IQ group showed a significant effect from the Android worksheet application on student's achievement meanwhile for the average IQ group there was no effect.

To examine dual trajectories of anxiety/depression symptoms and alcohol use among drug-using youth seeking care from an urban emergency department (ED), their baseline correlates and co-occurring trajectories of severe violence. There were five characteristic dual trajectories of alcohol use and depression/anxiety symptoms. Community violence exposure was highest among individuals with high-depression/anxiety symptom trajectories. Individuals with concurrently high-alcohol use and depression/anxiety symptom trajectories reported that the most delinquent peer affiliations, and had the highest rates of severe violence over time. We analyzed data from 599 drug-using (primarily marijuana) youth ages 14-24 (349 assault-injured) recruited from December 2009 to September 2011 into a 24-month longitudinal study at a Level-1 ED in Flint, Michigan. Youth self-reported substance use, depression and anxiety symptoms, peer/parental behaviors, and severe violence involvement at baseline and four biannual follow-up assessments. Bivariate latent trajectory models identified homogeneous groups with similar trajectories on alcohol use and anxiety/depression symptoms; we compared baseline characteristics of each trajectory group and concurrent trajectories of severe violence (victimization and aggression). Our model identified five trajectory groups: Low drinking/No symptoms (LN; 10.4%; n = 62), No drinking/Moderate symptoms (NM; 15.7%; n = 94), Low drinking/Moderate symptoms (LM; 30.2%; n = 181), Low drinking/High symptoms (LH; 16.4%; n = 98) and High drinking/High symptoms (HH; 27.5%; n = 164). The HH group was characterized by more delinquent peer associations, and rates of community violence were higher among the high symptom groups. The HH group had the highest severe violence perpetration and victimization rates across time points; the LH group had similar violence rates to the LM and NM groups and the LN group had the lowest violence rates across time. Among drug-using youth, alcohol use interventions could benefit from a focus on peer influences, and those with a joint focus on violence involvement may be improved via inclusion of content related to mental health and community violence exposure.

Spinal pain is a significant occupational health issue. Whilst neck pain and low back pain have received considerable attention, thoracic spinal pain (TSP) has not. The objective of this study was to systematically identify and report the evidence describing the prevalence and correlates of TSP within occupational groups. This literature review systematically searched for reports of TSP prevalence and associated factors for TSP in working adult cohorts using nine electronic databases. Studies were evaluated for level of evidence and epidemiologic data were narratively synthesised. 52 studies were identified describing 65 cohorts covering manual labourers, office workers, health professionals, manufacturing and industrial workers, drivers, military personnel and performing artists. Prevalence varied with occupational group and time period. One year prevalence of TSP ranged from 3.0-55.0%, with most occupational groups having medians around 30%. Significant odds ratios for individual (concurrent musculoskeletal disorders, exercising, pre-menstrual tension and female gender), general work-related (high work load, high work intensity, perceiving ergonomic problems in the workplace, working in some specialised areas, performing boring/tedious work tasks, certain year levels of study, employment duration, driving specialised vehicles, and a high number of flying hours), physical work-related (manual physiotherapy tasks, climbing stairs and high physical stress) and psychosocial work-related (perceived risk of injury and high mental pressure) factors were reported. The high median prevalence rates suggest TSP may be a significant occupational health problem. The multiple domains of associated factors point to the need for prospective research encompassing these domains to inform targeted occupational interventions.

This study grouped treatment-seeking individuals (n=1825) by common patterns of 12-step attendance using 5 waves of data (75% interviewed year-9) to isolate unique characteristics and use-related outcomes distinguishing each class profile. The high class reported the highest attendance and abstention. The descending class reported high baseline alcohol severity, long treatment episodes, and high initial attendance and abstinence; but by year-5 their attendance and abstinence dropped. The early-drop class, which started with high attendance and abstinence but with low problem severity, reported no attendance after year 1. The rising class, with fairly high alcohol and psychiatric severity throughout, reported initially low attendance, followed by increasing attendance paralleling their abstention. Last, the low and no classes, which reported low problem-severity and very low/no attendance, had the lowest abstention. Female gender and high alcohol severity predicted attendance all years. Consistent with a sustained benefit for 12-step exposure, abstinence patterns aligned much like attendance profiles. PMID:22206631

The behavioural repertoires and time budgets of 2 captive groups and 1 semi-free-ranging group of Cebus olivaceus were determined with the aim to assess the impact of the zoo environment on behaviour. The repertoires were qualitatively similar between groups and to those reported for wild troops, but the captive groups showed self-directed and stereotyped behaviours not reported in the wild. The differences in repertoires between groups were easily associated with the opportunity to interact directly with the visitors, with particularities of the enclosure and with the severity of confinement. Overall, females spent more time foraging than males in the 2 captive groups, and adults rested and watched more than subadults in all the groups. Time budgets were dominated by foraging, resting, movement and affiliative interactions, but their relative importance varied between groups, with foraging being especially prominent in the most confined group. The time budgets also varied qualitatively from those reported for wild troops. We conclude the species is behaviourally able to adjust to captivity, but the slight differences along the continuum from wild to semi-free to captive are suggestive of mild stress or social tension probably due to unstimulating environmental conditions, high visitor pressure and deviations from typical sex-age group composition.

The M6 working group had more than 40 active participants (listed in Section 4). During the three weeks at Snowmass, there were about 50 presentations, covering a wide range of topics associated with high intensity proton sources. The talks are listed in Section 5. This group also had joint sessions with a number of other working groups, including E1 (Neutrino Factories and Muon Colliders), E5 (Fixed-Target Experiments), M1 (Muon Based Systems), T4 (Particle Sources), T5 (Beam dynamics), T7 (High Performance Computing) and T9 (Diagnostics). The M6 group performed a survey of the beam parameters of existing and proposed high intensitymore » proton sources, in particular, of the proton drivers. The results are listed in Table 1. These parameters are compared with the requirements of high-energy physics users of secondary beams in Working Groups E1 and E5. According to the consensus reached in the E1 and E5 groups, the U.S. HEP program requires an intense proton source, a 1-4 MW Proton Driver, by the end of this decade.« less

Death anxiety is important but understudied in palliative care. New self-report measurements have been developed, but their interpretation and clinical utility may not be evident. To inform our understanding of death anxiety in patients with advanced cancer by exploring the relationship between this self-reported symptom and its clinical presentation. Participants were part of a psychotherapy trial in advanced cancer. First therapy session transcripts were analyzed using interpretive description in patients reporting low, moderate, and high death anxiety on the Death and Dying Distress Scale (DADDS). A total of 16 participants (10 women and 6 men) with advanced or metastatic cancer were sampled from the Princess Margaret Cancer Centre, Toronto, Canada. Six participants reported low death anxiety scores (Death and Dying Distress Scale: 0-19), five moderate (Death and Dying Distress Scale: 20-50), and five high (Death and Dying Distress Scale: 51-75). The low death anxiety group exhibited psychological readiness for death, or contrastingly, non-reflectiveness about death. The moderate group recognized the imminence of mortality, which impacted treatment decisions and future plans. Prior experience with death was discussed as raising the salience of mortality. The high group felt dominated by powerful emotions and could not make sense of their situation. Their distress was exacerbated by substantial relational concerns. Self-reported death anxiety is affected by the awareness and ability to reflect on mortality. Death and Dying Distress Scale scores may facilitate exploration of this symptom as part of a clinical assessment and may serve to guide treatment approaches. Greater attention to death anxiety is consistent with and recommended by contemporary approaches to palliative care. © The Author(s) 2016.

Primary prevention and early detection are integral strategies to reduce the burden of skin cancer. To describe the prevalence of sun protection and skin examination practices in a population exposed to high levels of ambient solar radiation and to identify associated factors. Cross-sectional analyses of baseline data from a prospective cohort of 40,172 adults aged 40 through 69 years from Queensland, Australia, recruited in 2011. We obtained data on all melanoma diagnoses through 2009 via record linkage with the Queensland Cancer Registry (notifications have been mandatory since 1982). We calculated prevalence proportion ratios to compare prevalence of sun protection and skin examination practices in 3 separate groups: those with a history of melanoma (group 1), those with a self-reported history of treated actinic lesions (group 2), and those without either (group 3). We used multivariate generalized linear models to identify factors associated with each practice. Participants with a previously confirmed melanoma (group 1; n = 1433) and/or treated actinic lesions (group 2; n = 24,006) were more likely than those without (group 3; n = 14,733) to report sun protection practices, including regular use of sunscreen (53.3%, 45.1%, and 38.1%, respectively) and wearing hats (74.7%, 68.2%, and 58.2%, respectively). They were also more likely to have had a whole-body skin examination by a physician in the past 3 years (93.7%, 83.4%, and 52.1%, respectively). Within all 3 groups, the strongest association with sun protection practices was with sun-sensitive skin type. Within group 3 (no history of treated skin lesions), the strongest factor associated with clinical skin examinations was self-reported nevus density at 21 years of age, whereas a family history of melanoma was a significant factor in groups 2 and 3. In this large sample exposed to high levels of ambient solar radiation, sun protection and skin examination practices were most frequent among those with a history of treated skin lesions or sun-sensitive skin types.

Power training has been shown to be more effective than conventional resistance training for improving physical function in older adults; however, most trials have used pneumatic machines during training. Considering that the general public typically has access to plate-loaded machines, the effectiveness and safety of power training using plate-loaded machines compared to pneumatic machines is an important consideration. The purpose of this investigation was to compare the effects of high-velocity training using pneumatic machines (Pn) versus standard plate-loaded machines (PL). Independently-living older adults, 60years or older were randomized into two groups: pneumatic machine (Pn, n=19) and plate-loaded machine (PL, n=17). After 12weeks of high-velocity training twice per week, groups were analyzed using an intention-to-treat approach. Primary outcomes were lower body power measured using a linear transducer and upper body power using medicine ball throw. Secondary outcomes included lower and upper body muscle muscle strength, the Physical Performance Battery (PPB), gallon jug test, the timed up-and-go test, and self-reported function using the Patient Reported Outcomes Measurement Information System (PROMIS) and an online video questionnaire. Outcome assessors were blinded to group membership. Lower body power significantly improved in both groups (Pn: 19%, PL: 31%), with no significant difference between the groups (Cohen's d=0.4, 95% CI (-1.1, 0.3)). Upper body power significantly improved only in the PL group, but showed no significant difference between the groups (Pn: 3%, PL: 6%). For balance, there was a significant difference between the groups favoring the Pn group (d=0.7, 95% CI (0.1, 1.4)); however, there were no statistically significant differences between groups for PPB, gallon jug transfer, muscle muscle strength, timed up-and-go or self-reported function. No serious adverse events were reported in either of the groups. Pneumatic and plate-loaded machines were effective in improving lower body power and physical function in older adults. The results suggest that power training can be safely and effectively performed by older adults using either pneumatic or plate-loaded machines. Copyright © 2017 Elsevier Inc. All rights reserved.

Determinants associated with high-risk sexual behaviors were investigated in 1,133 sexually active women in Bogotá, Colombia. A self-administered questionnaire was completed by two groups of women: 721 representing the general population (GP), and 412 commercial sex workers (CSWs). High-risk sexual behaviors for HIV/AIDS were evident in both groups. Nevertheless, consistent condom use was reported by only 6% of the GP group, as compared to 67% of the CSWs. Failure to recognize high-risk routes for HIV infection was indicated in 69% of the GP women for anal sex, and by the majority of both groups for intercourse during menses (56% GP women and 54% CSWs). Multivariate analysis revealed that education level, actual age, and age of first sex experience were significant predictors of high-risk sexual practices. The necessity for educational programs regarding high-risk sexual practices and risk of HIV/ AIDS is evident for HIV/AIDS prevention.

Background An increase in the number of dentists conducting tobacco-use cessation treatment is needed. The authors assessed the effects of high-intensity training (HIT) or low-intensity training (LIT) and reimbursement on general dentists’ tobacco-use–related attitudes and treatment behaviors. Methods The authors randomly selected 265 dentists in three states and assigned them to one of five groups: HIT workshop groups with and without tobacco-use cessation counseling reimbursement, LIT mailed self-study groups with and without reimbursement or a control group. Outcomes at follow-up were dentists’ self-reported tobacco-use–related attitudes and behaviors and patients’ reports of dentists’ behaviors. Results Significantly more dentists in the intervention groups reported having positive attitudes and behaviors at follow-up than did dentists in the control group. Dentists in the HIT groups, however, reported assessing patients’ willingness to quit and assisting them with the quitting process significantly more often than did dentists in the LIT groups. Significantly more patients of dentists in the intervention groups who used tobacco reported receiving advice and assistance from their dentists than did patients of dentists in the control group. Adding reimbursement to HIT or LIT conditions did not provide additional intervention effect. Conclusion Dentists trained by means of a workshop or self-study program used components of a recommended guideline more frequently and felt more positive toward tobacco-use cessation counseling than did dentists in the control group. Clinical Implications Although the workshop training was more successful than the self-study training, the latter’s reach among dentists could have a more significant public health impact. The effect of reimbursement needs further study. PMID:22653940

Purpose The purpose of this study was to compare outcomes of subjects with open-angle glaucoma (OAG) not controlled on one medication who underwent either implantation of two iStent inject® trabecular micro-bypass devices or received medical therapy consisting of a fixed combination of latanoprost/timolol. Patients and methods Of 192 subjects who qualified for the study and were enrolled, 94 were randomized to surgery with implantation of two iStent inject® devices in the treated eye and 98 to receive medical therapy. Results At the month 12 visit, 94.7% of eyes (89/94) in the stent group reported an unmedicated intraocular pressure (IOP) reduction of ≥20% versus baseline unmedicated IOP, and 91.8% of eyes (88/98) in the medical therapy group reported an IOP reduction ≥20% versus baseline unmedicated IOP. A 17.5% between-group treatment difference in favor of the iStent inject group was statistically significant (P=0.02) at the ≥50% level of IOP reduction. An IOP ≤18 mmHg was reported in 92.6% of eyes (87/94) in the iStent inject group and 89.8% of eyes (88/98) in the medical therapy group. Mean (standard deviation) IOP decreases from screening of 8.1 (2.6) mmHg and 7.3 (2.2) mmHg were reported in the iStent inject and medical therapy groups, respectively. A high safety profile was also noted in this study in both the iStent inject and medical therapy groups, as measured by stable best corrected visual acuity, cup-to-disc ratio, and adverse events. Conclusion These data show that the use of iStent inject is at least as effective as two medications, with the clinical benefit of reducing medication burden and assuring continuous treatment with full compliance to implant therapy as well as having a highly favorable safety profile.

The impact of a low-carbohydrate/high-protein diet compared with a high-carbohydrate/low-fat diet on ratings of hunger and cognitive eating restraint were examined. Overweight premenopausal women consumed a low-carbohydrate/high-protein (n=13) or high-carbohydrate/low-fat diet (n=15) for 6 weeks. Fasting body weight (BW) was measured and the Eating Inventory was completed at baseline, weeks 1 to 4, and week 6. All women experienced a reduction in BW (P<.01), although relative BW loss was greater in the low-carbohydrate/high-protein vs high-carbohydrate/low-fat group at week 6 (P<.05). Based on Eating Inventory scores, self-rated hunger decreased (P<.03) in women in the low-carbohydrate/high-protein but not in the high-carbohydrate/low-fat group from baseline to week 6. In both groups, self-rated cognitive eating restraint increased (P<.01) from baseline to week 1 and remained constant to week 6. Both diet groups reported increased cognitive eating restraint, facilitating short-term weight loss; however, the decrease in hunger perception in the low-carbohydrate/high-protein group may have contributed to a greater percentage of BW loss.

Previous studies have reported that credibility and content (argument quality) are the most critical factors affecting the quality of health information and its acceptance and use; however, this causal relationship merits further investigation in the context of health education. Moreover, message recipients' prior knowledge may moderate these relationships. This study used the elaboration likelihood model to determine the main effects of argument quality, source credibility and the moderating effect of self-reported diabetes knowledge on message attitudes. A between-subjects experimental design using an educational message concerning diabetes for manipulation was applied to validate the effects empirically. A total of 181 participants without diabetes were recruited from the Department of Health, Taipei City Government. Four group messages were manipulated in terms of argument quality (high and low) × source credibility (high and low). Argument quality and source credibility of health information significantly influenced the attitude of message recipients. The participants with high self-reported knowledge participants exhibited significant disapproval for messages with low argument quality. Effective health information should provide objective descriptions and cite reliable sources; in addition, it should provide accurate, customised messages for recipients who have high background knowledge level and ability to discern message quality. © 2017 Health Libraries Group Health Information & Libraries Journal.

Space systems in the future will probably include high-voltage, high-power energy-storage and -production systems. Two such technologies are high-voltage ac and dc systems and high-power electrodynamic tethers. The working group identified several plasma interaction phenomena that will occur in the operation of these power systems. The working group felt that building an understanding of these critical interaction issues meant that several gaps in our knowledge had to be filled, and that certain aspects of dc power systems have become fairly well understood. Examples of these current collection are in quiescent plasmas and snap over effects. However, high-voltage dc and almost all ac phenomena are, at best, inadequately understood. In addition, there is major uncertainty in the knowledge of coupling between plasmas and large scale current flows in space plasmas. These gaps in the knowledge are addressed.

Drug therapy problems, adverse drug events (ADEs), and symptom burden are high among adults with disabilities. To compare the effects of a modified medication therapy management (MTM) program within a self-efficacy workshop versus the workshop alone or usual care on symptom burden among adults with activity limitations. Three-group randomized controlled trial among adults (age 40 and older) with self-reported activity limitations in community practice. 8 weekly Living Well With a Disability (LWD) 2-hour workshop sessions with and without a collaborative medication management (CMM) module. mean number of moderate to very severe symptoms from a list of 11 physical and mental symptoms. Process measures: changes in medication regimens and self-reported ADEs. general linear mixed models (continuous outcomes) and generalized estimating equations (categorical outcomes). Participants had high symptom burden, low physical health, and took many medications. There was a significant increase in ADE reporting in the LWD + CMM group relative to the other 2 groups (Study group × Time P = .014), and there were significantly more changes in medication regimens in the LWD + CMM group (P = .013 LWD only vs LWD + CMM). The oldest third of participants had significantly fewer mean symptoms but received more intense CMM. There was no difference between the LWD-only, LWD + CMM, and usual care groups in symptom burden over time. Pharmacist MTM practices and MTM guidelines may need to be modified to affect symptom burden in a population with physical activity limitations.

Simulation technologies are gaining widespread acceptance across a variety of educational domains and applications. The current research examines whether basic nursing procedure training with high-fidelity versus low-fidelity mannequins results in differential skill acquisition and perceptions of simulator utility. Fifty-two first-year students were taught nasogastric tube and indwelling urinary catheter insertion in one of two ways. The first group learned nasogastric tube and urinary catheter insertion using high-fidelity and low-fidelity mannequins, respectively, and the second group learned nasogastric tube and urinary catheter insertion using low-fidelity and high-fidelity mannequins, respectively. The dependent measures included student performance on nasogastric tube and urinary catheter insertion testing, as measured by observer-based instruments, and self-report questionnaires probing student attitudes about the use of simulation in nursing education. Results demonstrated higher performance with high-fidelity than with low-fidelity mannequin training. In response to a self-report posttraining questionnaire, participants expressed a more positive attitude toward the high-fidelity mannequin, especially regarding its responsiveness and realism.
Self-reported tolerance influences prefrontal cortex hemodynamics and affective responses.

Tempest, Gavin; Parfitt, Gaynor

The relationship between cognitive and sensory processes in the brain contributes to the regulation of affective responses (pleasure-displeasure). Exercise can be used to manipulate sensory processes (by increasing physiological demand) in order to examine the role of dispositional traits that may influence an individual's ability to cognitively regulate these responses. With the use of near infrared spectroscopy, in this study we examined the influence of self-reported tolerance upon prefrontal cortex (PFC) hemodynamics and affective responses. The hemodynamic response was measured in individuals with high or low tolerance during an incremental exercise test. Sensory manipulation was standardized against metabolic processes (ventilatory threshold [VT] and respiratory compensation point [RCP]), and affective responses were recorded. The results showed that the high-tolerance group displayed a larger hemodynamic response within the right PFC above VT (which increased above RCP). The low-tolerance group showed a larger hemodynamic response within the left PFC above VT. The high-tolerance group reported a more positive/less negative affective response above VT. These findings provide direct neurophysiological evidence of differential hemodynamic responses within the PFC that are associated with tolerance in the presence of increased physiological demands. This study supports the role of dispositional traits and previous theorizing into the underlying mechanisms (cognitive vs. sensory processes) of affective responses.
Repressive coping and self-reports of parenting.

To investigate whether women who possess a repressive coping style (repressors) self-report more positive judgments of their childhood on questionnaire and repertory grid measures compared with non-repressors. Repressors (low anxiety-high defensiveness) were compared with a composite group of non-repressors, containing some low anxious (low anxiety-low defensiveness), some high anxious (high anxiety-low defensiveness), some defensive high anxious (high anxiety-high defensiveness) and some non-extreme scorers. Participants completed the Parental Bonding Instrument (PBI; Parker, Tupling & Brown, 1979) and a 10 x 10 repertory grid, Self-Identification Form. On the PBI, repressors scored significantly higher than non-repressors on paternal care and significantly lower on paternal overprotection. There were no group differences for maternal measures. On the repertory grid, repressors compared with non-repressors perceived (a) themselves as significantly closer to their father, a woman they like, and their ideal partner, and significantly further from a woman they dislike, and a man they dislike; and (b) their father as significantly closer to a woman they like, a partner/person they admire, and an ideal partner. In addition, repressors were significantly tighter on construing than non-repressors. The results supported the hypothesis that repressors would rate their interactions with their fathers more positively than non-repressors when allowed to do so on self-report measures.

Numerous studies document the adverse impact of racial discrimination on African Americans' health outcomes, but few have focused on HIV risk. We examined the relationship between racial discrimination and sexual risk in a sample of 526 Black heterosexual men and tested the hypothesis that social support would moderate this relationship. Participants in the predominantly low-income urban sample ranged in age from 18 to 45. High social support had a buffering impact on the relationship between racial discrimination and sexual risk. Among men reporting high racial discrimination, those with more social support reported less sexual risk than men with low social support. Men who reported high racial discrimination and low social support reported more sexual risk than men in any of the other groups. The study highlights social support as an important but understudied protective factor that may reduce sexual risk for Black heterosexual men who report high levels of racial discrimination.

To group participants according to markers of risk for severe mental illness based on subsyndromal symptoms reported in early adulthood and evaluate attributes of sleep across these risk categories. An online survey of sleep and psychiatric symptomatology (The Oxford Sleep Survey) was administered to students at one United Kingdom university. 1403 students (undergraduate and postgraduate) completed the survey. The median age was 21 (interquartile range = 20-23) and 55.60% were female. The cross-sectional data were used to cluster participants based on dimensional measures of psychiatric symptoms (hallucinations, paranoia, depression, anxiety, and (hypo)mania). High, medium, and low symptom groups were compared across sleep parameters: insomnia symptoms, nightmares, chronotype, and social jet lag. Insomnia symptoms, nightmares frequency, and nightmare-related distress increased in a dose-response manner with higher reported subsyndromal psychiatric symptoms (low, medium, and high). The high-risk group exhibited a later chronotype (mid sleep point for free days) than the medium- or low-risk group. The majority of participants (71.7%) in the high-risk group screened positive for insomnia and the median nightmare frequency was two per 14 days (moderately severe pathology). Insomnia, nightmares, and circadian phase delay are associated with increased subsyndromal psychiatric symptoms in young people. Each is a treatable sleep disorder and might be a target for early intervention to modify the subsequent progression of psychiatric disorder. © 2016 Associated Professional Sleep Societies, LLC.

American Indians/Alaska Natives (AI/AN) have the highest prevalence of obesity for any racial/ethnic group. Previous studies examining risk factors for obesity have identified excessive sugar-sweetened beverage (SSB) and inadequate water consumption as major risk factors for this population group. The historical scarcity of water in rural Alaska may explain consumption patterns including reliance on SSBs and other packaged drinks. Our study was designed to assess SSB, water and other beverage consumption and attitudes towards consumption in Alaska Native children and adults residing in rural Alaska. During summer 2014, 2 focus groups were conducted employing community members in a small rural village more than 200 air miles west of Fairbanks, Alaska. Interviews were completed with shop owners, Early Head Start and Head Start program instructors (n=7). SSB and total beverage intakes were measured using a modified version of the BEVQ-15, (n=69). High rates of SSB consumption (defined as sweetened juice beverages, soda, sweet tea, energy drink or sports drinks) and low rates of water consumption were reported for all age groups in the village. All adolescents and 81% of children reported drinking SSBs at least once per week in the last month, and 48% of adolescents and 29% of younger children reported daily consumption. Fifty-two per cent of adults reported consuming SSBs at least once per week and 20% reported daily consumption. Twenty-five per cent of adolescents reported never drinking water in the past month, and 19% of younger children and 21% of adults did not consume water daily. Alaska Native children and adults living in the Interior Alaska consume high amounts of SSBs including energy drinks and insufficient amounts of water. Interventions targeting beverage consumption are urgently needed for the Alaska Native population in rural Alaska.

Several reports suggest that obesity is a risk factor for osteoporosis. Vitamin K plays an important role in improving bone metabolism. This study examined the effects of vitamin K1 and vitamin K2 supplementation on the biochemical markers of bone turnover and morphological microstructure of the bones by using an obese mouse model. Four-week-old C57BL/6J male mice were fed a 10% fat normal diet group or a 45% kcal high-fat diet group, with or without 200 mg/1000 g vitamin K1 (Normal diet + K1, high-fat diet + K1) and 200 mg/1000 g vitamin K2 (Normal diet + K2, high-fat diet + K2) for 12 weeks. Serum levels of osteocalcin were higher in the high-fat diet + K2 group than in the high-fat diet group. Serum OPG level of the high-fat diet group, high-fat diet + K1 group, and high-fat diet + K2 group was 2.31 ± 0.31 ng/ml, 2.35 ± 0.12 ng/ml, and 2.90 ± 0.11 ng/ml, respectively. Serum level of RANKL in the high-fat diet group was significantly higher than that in the high-fat diet + K1 group and high-fat diet + K2 group (p<0.05). Vitamin K supplementation seems to tend to prevent bone loss in high-fat diet induced obese state. These findings suggest that vitamin K supplementation reversed the high fat diet induced bone deterioration by modulating osteoblast and osteoclast activities and prevent bone loss in a high-fat diet-induced obese mice.

This study investigated the conditions under which discrimination can lead to social identity changes among members of a minority group. Both positive and negative relations between perceptions of discrimination and social identity have previously been reported. To explain the conflicting results and understand the complex reality of members of stigmatized groups, we argue that group-based emotions (e.g., group-based dissatisfaction) and ambiguity of discrimination cues (i.e., overt vs. ambiguous) need to be considered. We hypothesized that perceptions of discrimination would play a moderating role between group-based dissatisfaction and social identity change in a context of ambiguous, but not of overt, discrimination. The sample was comprised of 151 Arab Muslims living in the province of Quebec. Participants read fictitious newspaper articles portraying either overt (n = 76) or ambiguous (n = 75) discrimination towards in-group members. Results revealed that for participants in the overt discrimination condition, only group-based dissatisfaction was positively associated with social identity change. In contrast, for the participants in the ambiguous discrimination condition, those who perceived little discrimination and felt low group-based dissatisfaction reported a decrease in social identity. However, those who perceived low group discrimination and felt high group-based dissatisfaction reported a positive social identity change. © 2016 The British Psychological Society.

Teaching undergraduates the process of peer review: learning by doing.

PubMed

Rangachari, P K

2010-09-01

An active approach allowed undergraduates in Health Sciences to learn the dynamics of peer review at first hand. A four-stage process was used. In stage 1, students formed self-selected groups to explore specific issues. In stage 2, each group posted their interim reports online on a specific date. Each student read all the other reports and prepared detailed critiques. In stage 3, each report was discussed at sessions where the lead discussant was selected at random. All students participated in the peer review process. The written critiques were collated and returned to each group, who were asked to resubmit their revised reports within 2 wk. In stage 4, final submissions accompanied by rebuttals were graded. Student responses to a questionnaire were highly positive. They recognized the individual steps in the standard peer review, appreciated the complexities involved, and got a first-hand experience of some of the inherent variabilities involved. The absence of formal presentations and the opportunity to read each other's reports permitted them to study issues in greater depth.
Object relations and differential treatment response to methadone maintenance.

PubMed

Nicholson, B; Treece, C

1981-07-01

The authors report results from a psychiatric study of narcotic addicts in which the relationship between specified aspects of object relations development and treatment response to methadone maintenance was examined. Two groups were defined as high and low drug users (in addition to the prescribed methadone dose) depending upon the frequency and intensity of additional drug use; a middle group was excluded. Thirty subjects participated. The dimensions of separation/individuation, narcissistic development, and self and object representations were measured by 12 scaled variables; scores of the high and low drug users were compared by t-test. In all cases, the high use group was found to be more impaired than the low use group. However, the dimensions differed greatly in their ability to differentiate the groups. The strongest group differences were found in the area of narcissistic development, with the high user group significantly more impaired than the low user group. The strength of these findings lends empirical support to the notion that an addict population can be differentiated on diagnostic and ego psychological measures. This has important implications for methadone maintenance treatment programs, and, possibly, for drug programs in general.

The World Health Organization recognizes sexual health as a fundamental right that should be guaranteed to all individuals. Sexual dysfunction affects various aspects in the lives (physical, psychic, and social) of affected persons. To assess the different types of sexual dysfunction, the quality of life (QOL), depression, anxiety, and levels of self-esteem observed in 165 men with sexual dysfunction, both with and without spinal cord injury (SCI). Case control study of 85 men with SCI and sexual dysfunction, and 80 men without SCI that have sexual dysfunction. The Sexual Health Evaluation Scale, the Fugl-Meyer Life Satisfaction Questionnaire scale, the Hospital Anxiety and Depression Scale, the Evaluation of the Sexual Health Scale, and Rosenberg's Self-esteem Scale were all used for data collection. Of the members in group A (with SCI), 89.4% (76) showed erectile dysfunction, and 75.2% (64) reported anejaculation. In group B (without SCI), 75 (96.8%) showed erectile dysfunction, and 58.7% (47) had disorders of sexual desire. In group A, 16.47 % (14) showed signs of depression, and 35.3% (30) had signs of anxiety. In group B, 30% (24) had elevated scores regarding depression, and 48.75% (39) had high scores for anxiety. All of the participants reported a high general QOL and a high satisfaction with their QOL but reported that their satisfaction with their sexual lives was only at the acceptable level. Social QOL is significantly higher in the SCI group (t Student P=0.031). The QOL, self-esteem, and anxiety and depression levels are significantly correlated. Men with sexual dysfunction strive to adapt to their situations, with the relationship between the type of sexual dysfunction and the QOL, mood (depression), and self-esteem all being important considerations. Sexuality and employment status are the areas where men with spinal cord injuries report less satisfaction. © 2014 International Society for Sexual Medicine.

Abstract Background Existing literature suggests that the effectiveness of a support group is linked to the qualifications, skills and experience of the group leader. Yet, little research has been conducted into the experiences of trained vs. untrained support group leaders of chronic‐illness support groups. The current study aimed to compare the experience of leaders, trained vs. untrained in group facilitation, in terms of challenges, rewards and psychological wellbeing. Methods A total of 358 Australian leaders of cancer and multiple sclerosis (MS) support groups, recruited through State Cancer Councils and the MS society (response rate of 66%), completed a mailed survey. Results Compared with untrained leaders, those with training were significantly younger, leading smaller groups and facilitating more groups, more frequently (all P < 0.05). Trained leaders were more likely to be female, educated beyond high school, paid to facilitate, a recipient of formal supervision and more experienced (in years) (all P < 0.01). Untrained leaders reported more challenges than trained leaders (P < 0.03), particularly struggling with being contacted outside of group meetings (52%) and a lack of leadership training (47%). Regardless of level of training, leaders identified a number of unmet support and training needs. Overwhelmingly, leaders found their facilitation role rewarding and the majority reported a high level of psychological wellbeing. Conclusions Group facilitator training has the potential to reduce the burden of support group leadership. Developing interventions to assist support group leaders will be particularly beneficial for leaders with minimal or no training group facilitation training. PMID:20550596
Psychosocial Characteristics Associated with Both Antiretroviral Therapy Adherence and Risk Behaviors in Women Living with HIV

The purpose of this study was to identify key psychosocial characteristics of HIV-infected women who exhibit different levels of both ART adherence and risk behaviors. We analyzed baseline data from 193 predominately African American HIV-infected women participating in a behavioral clinical trial. Women were categorized into high/low groups based on levels of adherence and risky behaviors. There was a significant interaction effect for internal motivation for adherence. Women at high risk for poor health and transmitting HIV (low adherence/high risk group) had the lowest levels of internal motivation and also reported more difficult life circumstances. Gender roles, caretaking and reliance on men for economic and other support may promote external versus internal motivation as well as riskier behaviors in this group. The highest levels of internal motivation were found in those with High Adherence/High Risk behaviors. This group was highly knowledgeable about HIV and had the lowest VL. Compared to others, this group seems to tolerate risky behaviors given their high level of adherence. Adherence and risk reduction behaviors are key to individual and public health. Motivation and risk compensation should be addressed when providing interventions to women living with HIV. PMID:26452670

Our systematic review identified 21 quantitative articles and eight qualitative articles addressing dating violence among high risk young women. The groups of high-risk young women in this review include street-involved, justice-involved, pregnant or parenting, involved with Child Protective Services, and youth diagnosed with a mental health issue. Our meta-analysis of the quantitative articles indicated that 34% (CI = 0.24–0.45) of high-risk young women report that they have been victims of physical dating violence and 45% (CI = 0.31–0.61) of these young women report perpetrating physical dating violence. Significant moderator variables included questionnaire and timeframe. Meta-synthesis of the qualitative studies revealed that high-risk young women report perpetrating dating violence to gain power and respect, whereas women report becoming victims of dating violence due to increased vulnerability.

An anonymous questionnaire was administered to 6,594 seventh- to twelfth-grade students in northeast Ohio. Separate analyses were conducted on sub-samples of respondents reporting no prior use of each substance. Within each of these 3 sub-samples, respondents were classified as holding high-risk intentions if they reported that they intended to begin using that particular substance within the next 6 months or were "not sure" of their intentions. Those reporting that they did not intend to start using a substance were classified as holding low-risk intentions. Multivariate logistic regression analyses examined the relations between normative beliefs and intention status (low- vs. high-risk), while accounting for socio-demographic characteristics. Across all 3 substances, normative beliefs were stronger predictors of intention status than socio-demographic variables. Higher levels of perceived acceptability and perceived prevalence were associated with holding high-risk intentions. Normative belief measures assessing close friend and sibling reference groups were much more important in explaining intention status than those assessing other reference groups (e.g., same age peers). Among adolescents with no prior use, normative beliefs concerning close friends and siblings may play an important role in the catalysis and support of intentions to initiate substance use. These findings challenge the utility of primary prevention strategies that provide normative feedback based on rates of substance use among distal reference groups.

Music has the potential to be an effective and engaging therapeutic intervention in the treatment of mental illness. This research area remains underdeveloped. This paper reports the feasibility of an innovative low-intensity CBT-based music (CBT-Music) group targeted to symptoms of depression and anxiety. A total of 28 participants with symptoms of depression and anxiety who were attending community mental health services were recruited for the study and randomized into TAU (treatment as usual) plus low-intensity CBT-Music (treatment) or to TAU alone (control). The treatment group consisted of a 9-week music group that incorporated various components of CBT material into a musical context. Feasibility was the primary outcome. The secondary outcomes were a reduction in depression, anxiety (Hospital Anxiety and Depression Scale) and disability (WHO Disability Assessment Schedule 2.0) assessed at baseline and 10 weeks. Recruitment proved feasible, retention rates were high, and the participants reported a high level of acceptability. A randomized control study design was successfully implemented as there were no significant differences between treatment and control groups at baseline. Participants in the treatment group showed improvement in disability (p = 0.027). Despite a reduction in depression and anxiety scores, these differences were not statistically significant. A low-intensity CBT-based music group can be successfully administered to clients of community mental health services. There are indications of effectiveness in reducing disability, although there appears to be negligible effect on symptoms of anxiety and depression. This is the first report of a trial of a low-intensity CBT-based music group intervention.
Repeating the errors of our parents? Parental violence in men's family of origin and conflict management in dating couples.

Within a social learning model, family-of-origin violence places men at risk for developing negative communication in their adult relationships. Thirty young men exposed to family-of-origin violence (exposed group) and 30 unexposed young men were videotaped discussing a conflict topic with their female dating partners. Relative to the unexposed group, the exposed men and women reported higher relationship aggression and during discussion showed more negative communication, were more domineering, and the men reported more negative affect. There were no differences between the groups on cognition or heart rate. The conflict management deficits and aggression evident in the exposed group suggest that these partners are at high risk for future relationship aggression and distress.
An examination of psychosocial correlates of eating disorders among female collegiate athletes.

Petrie, Trent A; Greenleaf, Christy; Reel, Justine J; Carter, Jennifer E

2009-09-01

With female collegiate athletes, we examined the relationship of eating pathology to body image concerns, weight pressures, sociocultural internalization, and mood state. Multivariate analyses revealed that the symptomatic and eating disorder groups were similar on seven of eight weight pressures, three of four mood states, on internalization, and on five of six body image measures; in all instances, these two groups reported more pathological scores than the asymptomatic athletes. Except for pressures from coaches, the psychosocial variables differentiated the groups, correctly classifying 79% of the cases. These findings suggest that athletes symptomatic of eating disorders report similarly high levels of disturbance across a wide range of psychosocial risk factors, and both groups warrant prevention and treatment efforts.

The primary objective of this study was to examine how a group of Swedish teachers rate aspects of their working environment that can be presumed to have an impact on vocal behavior and voice problems. The secondary objective was to explore the prevalence of voice problems in Swedish teachers. Questionnaires were distributed to the teachers of 23 randomized schools. Teaching staff at all levels were included, except preschool teachers and teachers at specialized, vocational high schools. The response rate was 73%. The results showed that 13% of the whole group reported voice problems occurring sometimes, often, or always. The teachers reporting voice problems were compared with those without problems. There were significant differences among the groups for several items. The teachers with voice problems rated items on room acoustics and work environment as more noticeable. This group also reported voice symptoms, such as hoarseness, throat clearing, and voice change, to a significantly higher degree, even though teachers in both groups reported some voice symptoms. Absence from work because of voice problems was also significantly more common in the group with voice problems--35% versus 9% in the group without problems. We may conclude that teachers suffering from voice problems react stronger to loading factors in the teaching environment, report more frequent symptoms of voice discomfort, and are more often absent from work because of voice problems than their voice-healthy colleagues.

Considering sport participation as a source for physical activity among adolescents.

PubMed

Pharr, Jennifer; Lough, Nancy L

2014-07-01

Studies have shown participation in sport is lower among girls than boys, decreases as students matriculate through high school, is lowest among Black and Hispanic girls and has a positive relationship with SES. With sport recognized as a contributor to physical activity and health in adolescents, consideration of diminishing rates of participation appears warranted. The purpose of this study was to identify patterns related to differences in self-reported sport participation between genders, ethnic groups, grades and SES. This study was a cross-sectional, secondary analysis of data collected for a sport interest survey. All students in grades 8-11 attending middle and high schools were provided an opportunity to participate in the survey. Data from 49,832 students were analyzed. Among the participants, Black girls participated more and White girls participated less than expected. Black boys participated more while White and Asian boys participated less than expected. Reported sport participation was high compared with national data when analyzed by gender and ethnic group. Sport participation was higher in low SES schools compared with high SES schools. The importance of sport as a source of physical activity in underserved groups is significant.

To compare clinicopathological features and long-term outcome in gastric cancer patients coming from high-risk and low-risk areas of Italy. Better survival rates have been reported from countries with higher incidence of gastric cancer. Data regarding 829 patients coming from Tuscany (group A) and 143 patients coming from Southern Italy (group B) were analyzed. Mean follow-up time was 56 +/- 57 months; it was 85 +/- 63 months in surviving patients or not tumor-related deaths. Prognostic factors were investigated by multivariate analysis with Cox proportional hazard model after verifying the assumption of proportionality of the risk associated with covariates. Lauren diffuse-mixed histotype, younger age, extended lymphadenectomy, and advanced stages were more common in group B. Gastric cancer-related 10-year survival probability was 48% in group A versus 29% in group B (log-rank test: P < 0.001). By multivariate analysis, geographic area was confirmed as a significant prognostic factor (hazard ratio for group B vs. group A: 1.52, 95% confidence interval: 1.12-2.06, P = 0.006). The influence of this factor on long-term survival was independent from other clinical, surgical, and pathologic factors, and was notable in neoplasms involving the serosa (10-year survival probability: 15% in group A vs. 3% in group B, log-rank test: P = 0.005). Patients coming from low-risk area of Italy showed distinct pathologic features, more advanced stage, and worse prognosis when compared with patients coming from high-risk area. These findings may be indicative of different tumor biology, and may contribute to partly explain worldwide geographic variability in prognosis reported in different series.

Emotion dysregulation is a core feature of borderline personality disorder (BPD). So far, many studies have tested the consequences of the implementation of certain emotion regulation (ER) strategies, but there have been no investigations about ER choices in BPD. Thus, the aim of this study was to investigate habitual ER choices by self-report questionnaires and experimentally by testing the preference to select between distraction and reappraisal when facing different emotional intensities (high vs. low) and contents (borderline-specific vs. unspecific negative) in patients with BPD (n=24) compared with clinical controls (patients with major depression, n=19) and a healthy control group (n=32). Additionally, heart rate (HR) responses were continuously assessed. Main results revealed that both patient groups showed maladaptive self-reported ER choice profiles compared with HC. We found, however, no differences between the groups in the choice of distraction and reappraisal on the behavioral level and in HR responses. In BPD, within-group analyses revealed a positive correlation between symptom severity and the preference for distraction under high-intensity borderline-specific stimuli. Our findings provide preliminary evidence of ER choices in BPD and show the robustness of the choice effect in patients with affective disorders. Copyright © 2016 Elsevier Ireland Ltd.

Callous-unemotional (CU) traits are a risk factor for a severe, aggressive, and persistent pattern of conduct problems (CP). This study investigated characteristics that might differentiate children with elevated CU traits with and without CP in an effort to identify factors that may reduce the risk for CP in children with limited prosocial emotions. Utilizing a sample of 1,366 children from Cyprus, five groups were identified for further study based on latent profile analysis: low-risk (67.2%), high-CP/low-CU (7.9%), high-CU (9.4%), moderate-CP/CU (8.4%), and high-CP/CU (7.2%). The identified groups were compared on behavioral and social measures. There were significant main effects of group for: impulsivity and executive functioning; parenting; and connectedness to school. The high-CU group had significantly lower hyperactivity-impulsivity and executive functioning deficits, significantly higher self-regulation, and their mothers reported more maternal involvement and positive parenting than those in the high-CP/CU group. Also, the high-CU group showed more school connectedness than those in the high-CP/CU group. These findings highlight several factors in the child and in his or her social environment that are associated with CU traits in the absence of serious CP and that may suggest targets for intervention for youth who may lack prosocial emotions. © 2016 Association for Child and Adolescent Mental Health.
Left ear dichotic listening performance on consonant-vowel combinations and digits in subtypes of reading-disabled children.

Morton, L L; Siegel, L S

1991-02-01

Twenty reading comprehension-disabled (CD) and 20 reading comprehension and word recognition-disabled (CWRD), right-handed male children were matched with 20 normal-achieving age-matched controls and 20 normal-achieving reading level-matched controls and tested for left ear report on dichotic listening tasks using digits and consonant-vowel combinations (CVs). Left ear report for CVs and digits did not correlate for any of the groups. Both reading-disabled groups showed lower left ear report on digits. On CVs the CD group showed a high left ear report but only when there were no priming precursors, such as directions to attend right first and to process digits first. Priming effects interfered with the processing of both digits and CVs. Theoretically, the CWRD group seems to be characterized by a depressed right hemisphere, whereas the CD group may have a more labile right hemisphere, perhaps tending to overengagement for CV tasks but vulnerable to situational precursors in the form of priming effects. Implications extend to (1) subtyping practices in research with the learning-disabled, (2) inferences drawn from studies using different dichotic stimuli, and (3) the neuropsychology of reading disorders.

Different doses of prophylactic platelet transfusion for preventing bleeding in people with haematological disorders after myelosuppressive chemotherapy or stem cell transplantation

Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in people who are thrombocytopenic due to bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004, and updated in 2012 that addressed four separate questions: prophylactic versus therapeutic-only platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. This review has now been split into four smaller reviews; this review compares different platelet transfusion doses. Objectives To determine whether different doses of prophylactic platelet transfusions (platelet transfusions given to prevent bleeding) affect their efficacy and safety in preventing bleeding in people with haematological disorders undergoing myelosuppressive chemotherapy with or without haematopoietic stem cell transplantation (HSCT). Search methods We searched for randomised controlled trials in the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950), and ongoing trial databases to 23 July 2015. Selection criteria Randomised controlled trials involving transfusions of platelet concentrates, prepared either from individual units of whole blood or by apheresis, and given to prevent bleeding in people with malignant haematological disorders or undergoing HSCT that compared different platelet component doses (low dose 1.1 × 1011/m2 ± 25%, standard dose 2.2 × 1011/m2 ± 25%, high dose 4.4 × 1011/m2 ± 25%). Data collection and analysis We used the standard methodological procedures expected by The Cochrane Collaboration. Main results We included seven trials (1814 participants) in this review; six were conducted during one course of treatment (chemotherapy or HSCT). Overall the methodological quality of studies was low to moderate across different outcomes according to GRADE methodology. None of the included studies were at low risk of bias in every domain, and all the included studies had some threats to validity. Five studies reported the number of participants with at least one clinically significant bleeding episode within 30 days from the start of the study. There was no difference in the number of participants with a clinically significant bleeding episode between the low-dose and standard-dose groups (four studies; 1170 participants; risk ratio (RR) 1.04, 95% confidence interval (CI) 0.95 to 1.13; moderate-quality evidence); low-dose and high-dose groups (one study; 849 participants; RR 1.02, 95% CI 0.93 to 1.11; moderate-quality evidence); or high-dose and standard-dose groups (two studies; 951 participants; RR 1.02, 95% CI 0.93 to 1.11; moderate-quality evidence). Three studies reported the number of days with a clinically significant bleeding event per participant. There was no difference in the number of days of bleeding per participant between the low-dose and standard-dose groups (two studies; 230 participants; mean difference −0.17, 95% CI −0.51 to 0.17; low quality evidence). One study (855 participants) showed no difference in the number of days of bleeding per participant between high-dose and standard-dose groups, or between low-dose and high-dose groups (849 participants). Three studies reported the number of participants with severe or life-threatening bleeding. There was no difference in the number of participants with severe or life-threatening bleeding between a low-dose and a standard-dose platelet transfusion policy (three studies; 1059 participants; RR 1.33, 95% CI 0.91 to 1.92; low-quality evidence); low-dose and high-dose groups (one study; 849 participants; RR 1.20, 95% CI 0.82 to 1.77; low-quality evidence); or high-dose and standard-dose groups (one study; 855 participants; RR 1.11, 95% CI 0.73 to 1.68; low-quality evidence). Two studies reported the time to first bleeding episodes; we were unable to perform a meta-analysis. Both studies (959 participants) individually found that the time to first bleeding episode was either the same, or longer, in the low-dose group compared to the standard-dose group. One study (855 participants) found that the time to the first bleeding episode was the same in the high-dose group compared to the standard-dose group. Three studies reported all-cause mortality within 30 days from the start of the study. There was no difference in all-cause mortality between treatment arms (low-dose versus standard-dose: three studies; 1070 participants; RR 2.04, 95% CI 0.70 to 5.93; low-quality evidence; low-dose versus high-dose: one study; 849 participants; RR 1.33, 95% CI 0.50 to 3.54; low-quality evidence; and high-dose versus standard-dose: one study; 855 participants; RR 1.71, 95% CI 0.51 to 5.81; low-quality evidence). Six studies reported the number of platelet transfusions; we were unable to perform a meta-analysis. Two studies (959 participants) out of three (1070 participants) found that a low-dose transfusion strategy led to more transfusion episodes than a standard-dose. One study (849 participants) found that a low-dose transfusion strategy led to more transfusion episodes than a high-dose strategy. One study (855 participants) out of three (1007 participants) found no difference in the number of platelet transfusions between the high-dose and standard-dose groups. One study reported on transfusion reactions. This study’s authors suggested that a high-dose platelet transfusion strategy may lead to a higher rate of transfusion-related adverse events. None of the studies reported quality-of-life. Authors’ conclusions In haematology patients who are thrombocytopenic due to myelosuppressive chemotherapy or HSCT, we found no evidence to suggest that a low-dose platelet transfusion policy is associated with an increased bleeding risk compared to a standard-dose or high-dose policy, or that a high-dose platelet transfusion policy is associated with a decreased risk of bleeding when compared to a standard-dose policy. A low-dose platelet transfusion strategy leads to an increased number of transfusion episodes compared to a standard-dose strategy. A high-dose platelet transfusion strategy does not decrease the number of transfusion episodes per participant compared to a standard-dose regimen, and it may increase the number of transfusion-related adverse events. Findings from this review would suggest a change from current practice, with low-dose platelet transfusions used for people receiving in-patient treatment for their haematological disorder and high-dose platelet transfusion strategies not being used routinely.

To determine if a group social skills intervention program improves social competence and quality of life (QOL) in pediatric brain tumor survivors (PBTS). We conducted a randomized control trial in which PBTS (8-16 years old, off therapy for over 3 months) were allocated to receive social skills training (eg, cooperation, assertion, using social cognitive problem solving strategies, role playing, games, and arts and crafts) in 8 weekly 2-hour sessions, or an attention placebo control (games and arts and crafts only). Outcomes were self-reported, proxy-reported (caregiver), and teacher-reported using the Social Skills Rating System (SSRS), to measure social competence, and the Pediatric Quality of Life (PedsQL4.0, generic) to measure QOL at baseline, after intervention, and at 6 months follow-up. At baseline, SSRS were stratified into low and high scores and included as a covariate in the analysis. Compared to controls (n = 48), PBTS in the intervention group (n = 43) reported significantly better total and empathy SSRS scores, with improvements persisting at follow-up. The PBTS in the intervention group who had low scores at baseline reported the greatest improvements. Proxy and teacher reports showed no intervention effect. Participating in group social skills intervention can improve self-reported social competence that persisted to follow up. The PBTS should be given the opportunity to participate in social skills groups to improve social competence. Copyright © 2017 John Wiley & Sons, Ltd.
Morgellons disease: Analysis of a population with clinically confirmed microscopic subcutaneous fibers of unknown etiology.

Morgellons disease is a controversial illness in which patients complain of stinging, burning, and biting sensations under the skin. Unusual subcutaneous fibers are the unique objective finding. The etiology of Morgellons disease is unknown, and diagnostic criteria have yet to be established. Our goal was to identify prevalent symptoms in patients with clinically confirmed subcutaneous fibers in order to develop a case definition for Morgellons disease. Patients with subcutaneous fibers observed on physical examination (designated as the fiber group) were evaluated using a data extraction tool that measured clinical and demographic characteristics. The prevalence of symptoms common to the fiber group was then compared with the prevalence of these symptoms in patients with Lyme disease and no complaints of skin fibers. The fiber group consisted of 122 patients. Significant findings in this group were an association with tick-borne diseases and hypothyroidism, high numbers from two states (Texas and California), high prevalence in middle-aged Caucasian women, and an increased prevalence of smoking and substance abuse. Although depression was noted in 29% of the fiber patients, pre-existing delusional disease was not reported. After adjusting for nonspecific symptoms, the most common symptoms reported in the fiber group were: crawling sensations under the skin; spontaneously appearing, slow-healing lesions; hyperpigmented scars when lesions heal; intense pruritus; seed-like objects, black specks, or "fuzz balls" in lesions or on intact skin; fine, thread-like fibers of varying colors in lesions and intact skin; lesions containing thick, tough, translucent fibers that are highly resistant to extraction; and a sensation of something trying to penetrate the skin from the inside out. This study of the largest clinical cohort reported to date provides the basis for an accurate and clinically useful case definition for Morgellons disease.

Group-based trajectory modeling was used to explore empirical trajectories of symptoms of posttraumatic stress disorder (PTSD) among 17,062 adult area residents/workers (nonrescue/recovery workers) enrolled in the World Trade Center (WTC) Health Registry using 3 administrations of the PTSD Checklist (PCL) over 9 years of observation. Six trajectories described PTSD over time: low-stable (48.9%), moderate-stable (28.3%), moderate-increasing (8.2%), high-stable (6.0%), high-decreasing (6.6 %), and very high-stable (2.0%). To examine factors associated with improving or worsening PTSD symptoms, groups with similar intercepts, but different trajectories were compared using bivariate analyses and logistic regression. The adjusted odds of being in the moderate-increasing relative to the moderate-stable group were significantly greater among enrollees reporting low social integration (OR = 2.18), WTC exposures (range = 1.34 to 1.53), job loss related to the September 11, 2001 disaster (OR = 1.41), or unmet mental health need/treatment (OR = 4.37). The odds of being in the high-stable relative to the high-decreasing group were significantly greater among enrollees reporting low social integration (OR = 2.23), WTC exposures (range = 1.39 to 1.45), or unmet mental health need/treatment (OR = 3.42). The influence of severe exposures, scarce personal/financial resources, and treatment barriers on PTSD trajectories suggest a need for early and ongoing PTSD screening postdisaster.

Trends in Education-Specific Life Expectancy, Data Quality, and Shifting Education Distributions: A Note on Recent Research.

PubMed

Hendi, Arun S

2017-06-01

Several recent articles have reported conflicting conclusions about educational differences in life expectancy, and this is partly due to the use of unreliable data subject to a numerator-denominator bias previously reported as ranging from 20 % to 40 %. This article presents estimates of life expectancy and lifespan variation by education in the United States using more reliable data from the National Health Interview Survey. Contrary to prior conclusions in the literature, I find that life expectancy increased or stagnated since 1990 among all education-race-sex groups except for non-Hispanic white women with less than a high school education; there has been a robust increase in life expectancy among white high school graduates and a smaller increase among black female high school graduates; lifespan variation did not increase appreciably among high school graduates; and lifespan variation plays a very limited role in explaining educational gradients in mortality. I also discuss the key role that educational expansion may play in driving future changes in mortality gradients. Because of shifting education distributions, within an education-specific synthetic cohort, older age groups are less negatively selected than younger age groups. We could thus expect a greater concentration of mortality at younger ages among people with a high school education or less, which would be reflected in increasing lifespan variability for this group. Future studies of educational gradients in mortality should use more reliable data and should be mindful of the effects of shifting education distributions.
Female peers in small work groups enhance women's motivation, verbal participation, and career aspirations in engineering.

For years, public discourse in science education, technology, and policy-making has focused on the "leaky pipeline" problem: the observation that fewer women than men enter science, technology, engineering, and mathematics fields and more women than men leave. Less attention has focused on experimentally testing solutions to this problem. We report an experiment investigating one solution: we created "microenvironments" (small groups) in engineering with varying proportions of women to identify which environment increases motivation and participation, and whether outcomes depend on students' academic stage. Female engineering students were randomly assigned to one of three engineering groups of varying sex composition: 75% women, 50% women, or 25% women. For first-years, group composition had a large effect: women in female-majority and sex-parity groups felt less anxious than women in female-minority groups. However, among advanced students, sex composition had no effect on anxiety. Importantly, group composition significantly affected verbal participation, regardless of women's academic seniority: women participated more in female-majority groups than sex-parity or female-minority groups. Additionally, when assigned to female-minority groups, women who harbored implicit masculine stereotypes about engineering reported less confidence and engineering career aspirations. However, in sex-parity and female-majority groups, confidence and career aspirations remained high regardless of implicit stereotypes. These data suggest that creating small groups with high proportions of women in otherwise male-dominated fields is one way to keep women engaged and aspiring toward engineering careers. Although sex parity works sometimes, it is insufficient to boost women's verbal participation in group work, which often affects learning and mastery.

Little is known about how screen-based sedentary behavior at home and in preschool influences children’s health and activity patterns. The current study examined the individual and cumulative influence of TV viewing at home and in preschool on children’s physical activity (PA) and weight status. Children (n=339) attending 16 preschools in South Carolina were grouped into high and low TV groups based on parent report of children’s TV viewing at home and director report of TV use/rules in preschool. T-tests and mixed model ANOVAs examined differences in weight status and PA (min/hr) by high and low TV groups. Results revealed that children who were classified as High TV both at home and in preschool had significantly lower levels of moderate-to-vigorous PA compared with their Low TV counterparts. These findings demonstrate the importance of total environmental TV exposure on preschooler’s PA. Longitudinal and observational research to assess preschoolers’ cumulative screen-based sedentary behavior and its relationship with PA and weight status is needed. PMID:23502043

Resilient or Risk Group? Psychological Burden at Unaccompanied Refugee Minors (URM) in Germany Unaccompanied minors (umA in German) are considered as a risk group for psychological disorders. In international studies a high prevalence for trauma, anxiety, and depression were reported. A sample of N = 52 unaccompanied minors living in Germany was questioned on symptom severity as well as stress experience with the Refugee Health Screening-15. More than each second unaccompanied minor shows clinically relevant symptom severity and stress experience. In age-specific analyses the highest stress levels were found among the youngest unaccompanied minors. Therefore, specifically adapted settings for care should be applied for this high-risk group.

Sustainability of the Body Project, a dissonance-based selective eating disorder prevention program supported by efficacy and effectiveness trials, has not previously been examined. This mixed-methods study collected qualitative and quantitative data on training, supervision, and the intervention from 27 mental health clinicians from eight US universities who participated in an effectiveness trial and quantitative data on 2-year sustainability of program delivery. Clinicians, who were primarily masters-level mental health providers, had limited experience delivering manualized interventions. They rated the training and manual favorably, noting that they particularly liked the role-plays of session activities and intervention rationale, but requested more discussion of processes and group management issues. Clinicians were satisfied receiving emailed supervision based on videotape review. They reported enjoying delivering the Body Project but reported some challenges with the manualized format and time constraints. Most clinicians anticipated running more groups after the study ended but only four universities (50%) reported providing additional Body Project groups at the 1-year follow-up assessment and sustained delivery of the groups decreased substantially two years after study completion, with only one university (12%) continuing to deliver groups. The most commonly reported barriers for conducting additional groups were limited time and high staff turnover. PMID:26143559

Introduction Finding ways to provide better and less expensive health care for people with multiple chronic conditions or disability is a pressing concern. The purpose of this systematic review was to evaluate different approaches for caring for this high-need and high-cost population. Methods We searched Medline for articles published from May 31, 2008, through June 10, 2014, for relevant studies. Articles were considered eligible for this review if they met the following criteria: included people with multiple chronic conditions (behavioral or mental health) or disabilities (2 or more); addressed 1 or more of clinical outcomes, health care use and spending, or patient satisfaction; and compared results from an intervention group with a comparison group or baseline measurements. We extracted information on program characteristics, participant characteristics, and significant (positive and negative) clinical findings, patient satisfaction, and health care use outcomes. For each outcome, the number of significant and positive results was tabulated. Results Twenty-seven studies were included across 5 models of care. Of the 3 studies reporting patient satisfaction outcomes, 2 reported significant improvements; both were randomized controlled trials (RCTs). Of the 14 studies reporting clinical outcomes, 12 reported improvements (8 were RCTs). Of the 13 studies reporting health care use and spending outcomes, 12 reported significant improvements (2 were RCTs). Two models of care — care and case management and disease management — reported improvements in all 3 outcomes. For care and case management models, most improvements were related to health care use. For the disease management models, most improvements were related to clinical outcomes. Conclusions Care and case management as well as disease management may be promising models of care for people with multiple chronic conditions or disabilities. More research and consistent methods are needed to understand the most appropriate care for these high-need and high-cost patients. PMID:26564013

To analyze the epidemiological characteristics of measles before and after measles attenuated live vaccine (MV) supplementary immunization activities (SIAs) in Changzhou municipal in 2007-2008 and approach measures of measles elimination. Analyze measles epidemiology and control measures with descriptive epidemiology. After SIAs in Nov.2007, the reported measles incidence was 24.13/100000, and increased by 91.60% in 2008 than in 2007, except Jintan and Liyang town, the others were higher in 2008 than in 2007. The reported measles incidence of 5-9 years old was lower in 2008 than in 2007. However, the reported measles incidence of other age groups was higher. One incidence peak reached 216.92/100000 was found in < 1 year old group and another peak appeared at aged 20-30 years old group. The proportions of measles cases of 8 months-14 years old in 2007 and 2008 were 53.47% and 54.38%. 7.37% and 4.18% of them received MV respectively. The reported cases in 2008 increased and 68.05% of them were floating population. Low coverage of MVwas the main cause of high measles incidence. It indicated that a timely and strengthened routine vaccination, a high quality SIA, and well organized floating population management and surveillance are essential strategies to eliminate measles.

A number of studies have concluded that parents of children with ASD experience high levels of parenting stress. However, little is known about their parenting behaviors. Especially few studies investigated parenting in adolescence, although this period is associated with additional challenges for both adolescents and their parents. In the present study, a multi-method approach was used, combining data from a self-report questionnaire and observation of mother-child interactions during different semi-structured (e.g., inventing and building a vehicle of the future with construction toys) and structured tasks (e.g., solving marble maze). Linear mixed models (LMM) were used to compare the means of parenting behaviors among mothers of adolescents with (n = 44) and without ASD (n = 38), aged 12 to 16 years old. During the observations, mothers of adolescents with ASD showed more sensitivity and creativity, compared to the general population control group. In addition, mothers in the ASD group reported on the self-report questionnaire to adapt the environment more, for example, by establishing routines. Furthermore, this study investigated the role of maternal characteristics, that is, ASD characteristics and parenting stress. Parenting stress was associated with less self-reported positive parenting. Higher levels of ASD characteristics of the mother were related to more negativity and less sensitivity during the observation, and more self-reported harsh punishment and adapting the environment. This study additionally examined whether the impact of these maternal characteristics was the same across the two groups. Whereas group by parenting stress interaction effects were not significant for any of the observed and self-reported parenting behaviors, significant group by ASD characteristics interaction effects were noticed for self-reported harsh punishment and adapting the environment.

In this study, 44 adolescents with ASD and a control group of 38 adolescents without ASD, aged 12-16 years old, participated together with their mother. We compared parenting behaviors between the two groups, based on observations of mother-child interactions and a questionnaire that was filled out by the mother. During the observation, mothers of adolescents with ASD showed more sensitivity and creativity, compared to the control group. In addition, the questionnaire responses indicated that mothers in the ASD group adapted the environment more by for example, establishing routines.

Childhood Adversity and Pain Sensitization.

PubMed

You, Dokyoung Sophia; Meagher, Mary W

Childhood adversity is a vulnerability factor for chronic pain. However, the underlying pain mechanisms influenced by childhood adversity remain unknown. The aim of the current study was to evaluate the impact of childhood adversity on dynamic pain sensitivity in young adults. After screening for childhood adverse events and health status, healthy individuals reporting low (below median; n = 75) or high levels of adversity (the top 5%; n = 51) were invited for pain testing. Both groups underwent heat pain threshold and temporal summation of second pain (TSSP) testing after reporting depressive symptoms. TSSP refers to a progressive increase in pain intensity with repetition of identical noxious stimuli and is attributed to central sensitization. Changes in pain ratings over time (slope) were computed for TSSP sensitization and decay of subsequent aftersensations. The high-adversity group showed greater TSSP sensitization (meanslope, 0.75; SDpositive slope, 1.78), and a trend toward a slower decay (meanslope, -11.9; SD, 3.4), whereas the low-adversity group showed minimal sensitization (meanslope, 0.07; SDnear-zero slope, 1.77), F(1,123) = 5.84, p = .017 and faster decay (meanslope, -13.1; SD, 3.4), F(1,123) = 3.79, p = .054. This group difference remained significant even after adjusting for adult depressive symptoms (p = .033). No group difference was found in heat pain threshold (p = .85). Lastly, the high-adversity group showed blunted cardiac and skin conductance responses. These findings suggest that enhancement of central sensitization may provide a mechanism underlying the pain hypersensitivity and chronicity linked to childhood adversity.

Women who work commercially in sex work (female sex workers [FSW]) are considered a high-risk group for sexually transmissible infections (STI), yet the level of reported pathogens varies in studies around the world. This study reviewed STI rates reported in 42 studies of FSW around the world published between 1995 and 2006 and analysed the trends and types of populations surveyed, emphasising difficult to access FSW populations. Studies were retrieved by PUBMED and other search engines and were included if two or more pathogens were studied and valid laboratory methods were reported. The five most commonly assessed pathogens were Neisseria gonorrhea (prevalence 0.5-41.3), Chlamydia trachomatis (0.61-46.2), Treponema pallidum (syphilis; 1.5-60.5), HIV (0-76.6), and Trichomonas vaginalis (trichomoniasis; 0.11-51.0). Neisseria gonorrhea and C. trachomatis were the most commonly tested pathogens and high prevalence levels were found in diverse areas of the world. HIV was highly prevalent mostly in African countries. Although human papillomavirus infection was surveyed in few studies, prevalence rates were very high and its aetiological role in cervical cancer warrant its inclusion in future FSW monitoring. Hard-to-access FSW groups tended to have higher rates of STI. The five most commonly detected pathogens correspond to those that are highly prevalent in the general population, however there is an urgent need to develop rapid testing diagnostics for all five pathogens to increase prevention and treatment, especially in outreach programs to the most vulnerable groups among FSW.

Chronic low back pain (CLBP) is a highly prevalent and disabling musculoskeletal pain condition among older adults. Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat CLBP, however, TENS response for older adults compared to younger adults is untested. In a dose-response study stratified by age, sixty participants with axial CLBP (20 young, 20 middle-aged, 20 older) received four 20-minute sessions of high frequency, high intensity TENS over a two to three-week period in a laboratory-controlled setting. Experimental measures of pain sensitivity (mechanical pressure pain detection threshold, PPT) and central pain excitability (phasic heat temporal summation, TS; heat aftersensations, AS) were assessed before and after TENS. Episodic or immediate axial CLBP relief was assessed after TENS via measures of resting pain, movement-evoked-pain, and self-reported disability. Cumulative or prolonged axial CLBP relief was assessed by comparing daily pain report across sessions. Independent of age, individuals experienced episodic increase in PPT and reduction in AS following TENS application. Similarly, all groups, on average, experienced episodic axial CLBP relief via improved resting pain, movement-evoked pain, and disability report. Under this design, no cumulative effect was observed as daily pain did not improve for any age group across the four sessions. However, older adults received higher TENS amplitude across all sessions in achieving similar TENS responses to younger adults. These findings suggest that older adults experience similar episodic axial CLBP relief as younger individuals following high frequency, high intensity TENS when higher dosage parameters are used.

Objective: The aim of this study was to investigate trajectories of sleep quality and associations with mood in the perinatal period. Although it is commonly accepted that subjective sleep quality declines during pregnancy and the transition to parenthood, some women may follow qualitatively distinct trajectories. Design, Setting, and Participants: Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Data were collected from 293 women at four time points: during early pregnancy, at Time 1 (T1; < 22 w gestational age [GA]; late pregnancy, at Time 2 (T2; 32 w GA); during the postnatal period at Time 3 (T3; 3 mo postpartum); and Time 4 (T4; 6 mo postpartum). A group-based semiparametric mixture model was used to estimate patterns of sleep quality throughout the perinatal period. Results: Four trajectory groups were identified, including patterns defined by high sleep quality throughout (21.5%), mild decrease in sleep quality (59.5%), significant decrease in sleep quality (12.3%) and a group with poor sleep quality throughout (6.7%). Women who had the worst sleep quality at Time 1 and those who experienced significant increases in sleep problems throughout pregnancy were also the groups who reported the highest levels of anxiety and depressive symptoms in early pregnancy and the lowest levels of social support. After controlling for covariates, the groups with worst subjective sleep quality during pregnancy were also the most likely to experience high symptoms of depression in the postpartum period. Conclusions: Most of the women in our sample reported mild sleep disturbances through the perinatal period. A subgroup of women reported a significant decline in sleep quality from early to late pregnancy and another reported poor subjective sleep quality throughout pregnancy; these groups had the greatest risk of experiencing high symptoms of depression in the postpartum period.

In epidemiological studies high prevalence estimates for pathological Internet use in adolescence were reported. There are only few studies published, reporting data of adolescents seeking treatment concerning their pathological Internet use. Currently, a comparison of patients in inpatient versus outpatient treatment is not available. We investigated 74 adolescents reporting pathological Internet use with standardized questionnaires concerning problematic Internet use, psychopathological symptoms and life satisfaction. Overall, 35 adolescents were treated in an outpatient and another 39 adolescents in an inpatient setting. A substantial portion in both groups showed comorbid mental health problems. There were no differences in the degree of problematic Internet use between the two groups. However, compared to adolescents in an outpatient setting, adolescents in inpatient treatment reported longer average Internet usage times, a lower life satisfaction as well as more anxiety/depressiveness and self-esteem problems. In a multivariate logistic regression analysis Internet usage time and life satisfaction were identified as statistically significant factors for the affiliation to one of the two treatment groups. The results of the present study could be useful as a further description of this group of patients and more general to develop interventions for adolescents reporting pathological Internet use.

To evaluate whether the high-risk human papillomavirus (HPV) subtypes that are strongly related to cervical cancer are harbored in the prepuce of the circumcised tissue of prepubertal boys in the period just before active sexual life. The present study enrolled 30 healthy boys (age range 4-11 years, mean age 8.1 ± 1.6) who underwent a standard circumcision procedure, with hypospadias repair in 3 patients. All prepuceal samples were studied using real-time polymerase chain reaction and grouped according to HPV subtype prevalence as groups 1 (types 16 and 18), 2 (types 31, 33, 45, 52, and 58), and 3 (types 35, 39, 51, 56, 59, 66, and 68). HPV DNA was reported in 25 (83.3%) of the 30 subjects. All samples showed a negative result for group 2. Although most of the positive findings were for group 3 (25 [83.3%] of 30), a positive result was reported for only 1 subject for group 1 (3.3%). The results of the present study have shown that the prepuce harbored the rarest HPV types, including types 35, 39, 51, 56, 59, 66, and 68 in preadolescence boys with a high rate (83%). These findings are in contrast to the common knowledge of HPV prevalence in adults that points to the dominance of HPV subtypes 16 and 18. Copyright © 2012 Elsevier Inc. All rights reserved.

There is a growing body of evidence linking fish consumption and n-3 LCPUFAs to mental health. Still, the results from randomized trials with n-3 LCPUFAs show conflicting results, and it is possible that the combined effect of several nutrients in fish may explain the observed associations. To aim of the present study was to investigate if school meals with fatty fish three times per week for 12 weeks could alter mental health in a sample of typically developing adolescents. In the Fish Intervention Studies-TEENS (FINS-TEENS), adolescents from eight secondary schools (n=425) in Norway, were randomized to receive school meals with fatty fish, meat or n-3 LCPUFA supplements. Mental health was assessed with the Strengths and Difficulties Questionnaire (SDQ) and the differences between the groups were assessed with linear mixed effect models, unadjusted and adjusted for baseline and dietary compliance. The results showed no effects of school meals with fatty fish compared to similar meals with meat or n-3 LCPUFAs on the adolescents' self-reported symptom scores for mental health. Among adolescents scoring above the SDQ cut-offs (high-scorers), the fish- improved less than the meat group in the self-reported symptom scores for total difficulties- and emotional problems. However, the findings should be regarded as preliminary, as the analyses for the high-scorer group were underpowered. In conclusion, serving school meals with fatty fish did not alter mental health in a typically developing sample of adolescents. It is possible that serving healthy school meals with meat is more beneficial than similar meals with fatty fish in adolescents scoring high on mental health problems. However, the results should be seen as preliminary, as the dietary compliance in the fish group was low and the analyses in the high score group underpowered. Thus, further studies should investigate the associations between fish consumption and adolescents' mental health.

Previous research has investigated caregiver attachment relationships in children with autism during early childhood, with few differences found from matched control groups. However, little is known of this relationship during middle childhood (ages 8-12 years). In this study, the aim was to establish whether there are differences in the security of attachment in children with high-functioning autism compared to typically developing children. A secondary aim was to establish whether caregivers' perceptions of their child's attachment to them accorded with the children's own reports. Twenty-one children with high-functioning autism and 17 typically developing children were administered the Kerns Security Scale and the Inventory of Parent and Peer Attachment-Revised, and caregivers completed the same questionnaires from the viewpoint of their child. There were no differences between the groups in the children's and parents' reports of attachment security. Parents' and children's reports were moderately correlated on the Kerns Security Scale but were not correlated on the Inventory of Parent and Peer Attachment-Revised. The results indicate that levels of attachment security in children with high-functioning autism are not different from those in typically developing children. © The Author(s) 2013.

To explore high-risk behaviors and experiences with traffic law among night drivers in Curitiba, Brazil. Data from 398 drivers on sociodemographic parameters, high-risk behaviors, experiences with traffic law, and traffic law violations were collected through interviews conducted at sobriety checkpoints. Exploratory-descriptive and analytical statistics were used. The mean age of the participants was 32.6±11.2 years (range, 18 to 75 years). Half of the drivers reported having driven after drinking in the last year, predominantly single men aged 18 to 29 years who drive cars and drink alcohol frequently. Only 55% of the drivers who had driven after drinking in the last year self-reported some concern about being detected in a police operation. A significant association was found between sociodemographic variables and behavior, which can help tailor public interventions to a specific group of drivers: young men who exhibit high-risk behaviors in traffic, such as driving after drinking alcohol, some of whom report heavy alcohol consumption. This group represents a challenge for educational and enforcement interventions, particularly because they admit to violating current laws and have a low perception of punishment due to the low risk of being detected by the police.

The purpose of this longitudinal study was to identify distinct trajectories of cigarette smoking from sixth to twelfth grade and to characterize these trajectories by use of other drugs and high school dropout. The diverse sample for this analysis consisted of a cohort of 611 students from Northeast Georgia who participated in the Healthy Teens Longitudinal Study (2003-2009). Students completed seven yearly assessments from sixth through twelfth grade. We used semi-parametric, group-based modeling to identify groups of students whose smoking behavior followed a similar progression over time. Current smoking (past 30 day) increased from 6.9% among sixth graders to 28.8% among twelfth graders. Four developmental trajectories of cigarette smoking were identified: Abstainers/Sporadic Users (71.5% of the sample), Late Starters (11.3%), Experimenters (9.0%), and Continuous Users (8.2%). The Abstainer/Sporadic User trajectory was composed of two distinct groups: those who never reported any tobacco use (True Abstainers) and those who reported sporadic, low-level use (Sporadic Users). The True Abstainers reported significantly less use of alcohol and other drugs and lower dropout rates than students in all other trajectories, and Sporadic Users had worse outcomes than True Abstainers. Experimenters and Continuous Users reported the highest drug use. Over one-third of Late Starters (35.8%) and almost half of Continuous Users (44.4%) dropped out of high school. Cigarette smoking was associated with behavioral and academic problems. Results support early and continuous interventions to reduce use of tobacco and other drugs and prevent high school dropout. © The Author 2015.

This work examined whether combinations of academic and non-academic goals generated different motivational profiles in high school students. Besides, differences in homework behavioural engagement (i.e. amount of homework, time spent in homework, homework time management), homework emotional engagement (i.e. homework anxiety) and academic achievement were analysed. Participants were 714 high school students (43.4% boys and 56.6% girls). The study of potential motivational profiles was conducted by latent profile analysis, and the differences between the motivational profiles regarding homework variables and academic achievement were analysed using multivariate analysis. The results indicate the existence of five groups of motivational profiles: a group of students with multiple goals, a group of unmotivated students, two groups of students with a predominance of learning goals and, finally, a group comprising students with a high fear of failure. Both the group with multiple goals and the learning goals-oriented groups reported to do more homework, spending more time on homework, making better use of that time and having a higher academic achievement than counterparts. The avoidance-failure group and the group with multiple goals showed higher levels of homework anxiety. Globally, these results provide support for a person-centred approach. © 2016 International Union of Psychological Science.
Petrogenesis of High-CaO Lavas Recovered from Hawaii Scientific Drilling Project

Mauna Kea tholeiitic lavas recovered from Hawaii Scientific Drilling Project (HSDP) can be divided into three groups based on their major element compositions: High-SiO2, Low-SiO2, and High-CaO groups. Detailed geochemical and isotopic studies have been focused on the High- and Low-SiO2 group lavas, and High-CaO lavas were not well studied because they were not included in the original reference suite samples. Here we report trace element compositions determined on a suite of High-CaO glasses, and use these data to constrain the petrogenesis of High-CaO lavas. When normalized to Low-SiO2 lavas, High-CaO lavas form a U-shaped trace element pattern. That is, High-CaO lavas are enriched in both the most (Nb, Th) and the least (Sc, V) incompatible elements. This trace element difference is best explained if High-CaO parental magma represents a mixture of low degree partial melt of the Low-SiO2 mantle source and a mafic cumulate component. This mafic cumulate must be clinopyroxene-rich, and it could be delaminated mafic cumulate formed under arcs during continent formation, lower continental crust, or lower oceanic crust.Mauna Kea tholeiitic lavas recovered from Hawaii Scientific Drilling Project (HSDP) can be divided into three groups based on their major element compositions: High-SiO2, Low-SiO2, and High-CaO groups.

Aim: Present study aimed to systematically review and quantitatively synthesize published data about the prevalence of Hepatitis B Virus (HBV) infection among high risk groups in Iran. Background: Determining true burden of Hepatitis B Virus (HBV) infection among high-risk groups relies on knowledge of occurrence measures such as prevalence rate. There is no conclusive and comprehensive data regarding to prevalence of HBV infection among high risk groups in Iran. Methods: Relevant studies were searched in PubMed, Scopus, Web of Knowledge and local databases. In addition, reference lists of relevant studies were searched manually. Two independent authors reviewed the eligibility of retrieved studies and extracted the required data. Studies reporting HBV infection among high risk groups were included in the meta-analysis using random effects models. Meta regression and sub-group analysis were considered as additional analyses. Results: The initial search yielded 566 citations. After the primary screen, 37 studies were selected for review. Meta-analysis results showed that pooled prevalence of HBV infection among high risk groups in Iran was 4.8% (95% confidence interval: 3.6%-6.1%), with the highest prevalence among in prisoners (5%; 3%-6%), and in central regions of Iran (7%; 4%-11%). Year of study may affect the observed heterogeneity in the estimated prevalence of HBV infection among injection drug users (IDUs) and prisoners. Conclusion: Our results indicate that prevalence of HBV infection among high risk groups was seemingly high in Iran. Health policy decision makers should be aware of prevalence of HBV infection among different high risk groups and in different regions of Iran.

To describe the differences in socio-economic characteristics and body measurements between low, adequate and high energy reporting (LER, AER and HER) teenagers; furthermore, to investigate the relationship to misreporting mothers. Cross-sectional study. Habitual dietary intake was reported in a questionnaire. Classification into LER, AER and HER using the Goldberg equation within three activity groups based on physical activity questionnaire and calculated BMR. Stockholm, Sweden. Four hundred and forty-one 16-17-year-old teenagers (57 % girls) and their mothers. Of the teenagers, 17-19 % were classified as HER, while 13-16 % as LER. There was a highly significant trend from HER to LER in BMI (P < 0.001) and body fat % (P < 0.001). There was also a trend in number of working hours of mother (P = 0.01), family income (P = 0.008) and number of siblings (among boys only) (P = 0.02), but not in educational level of either father or mother. HER teenagers were lean, had mothers working fewer hours with lower income and had siblings. It was more likely that an LER girl had an LER mother than an AER mother (OR = 3.32; P = 0.002). The reasons for the high number of over-reporters could be many: misclassification due to growth, lacking established eating pattern due to young age or method-specific. Nevertheless, the inverted characteristic of HER compared to LER indicates that this is a specific group, worth further investigation.
Affective responsiveness, betrayal, and childhood abuse.

Several trauma-specific and emotion theories suggest that alterations in children's typical affective responses may serve an attachment function in the context of abuse by a caregiver or close other. For example, inhibiting negative emotional responses or expressions might help the child preserve a relationship with an abusive caregiver. Past research in this area has relied on self-report methods to discover links between affective responsiveness and caregiver abuse. Extending this literature, the current study used facial electromyography to assess affective responsiveness with 2 measures: mimicry of emotional facial expressions and affective modulation of startle. We predicted that women who reported childhood abuse by close others would show alterations in affective responsiveness relative to their peers. We tested 100 undergraduate women who reported histories of (a) childhood sexual or physical abuse by someone close, such as a parent (high-betrayal); (b) childhood abuse by someone not close (low-betrayal); or (c) no abuse in childhood (no-abuse). Especially when viewing women's emotional expressions, the high-betrayal group showed more mimicry of happy and less mimicry of angry faces relative to women who reported no- or low-betrayal abuse, who showed the opposite pattern. Furthermore, women who reported high-betrayal abuse showed less affective modulation of startle during pictures depicting men threatening women than did the other two groups. Findings suggest that, as predicted by betrayal trauma theory, women who have experienced high-betrayal abuse show alterations in automatic emotional processes consistent with caregiving-maintenance goals in an abusive environment.

The aim of this study was to examine the relationship between family environment (cohesion and parental bonding), high-risk status, and psychopathology (internalizing and externalizing problems) among offspring of parents with bipolar disorder (BD), from the perspective of both offspring and their parents. We further tested if family environment mediated the relationship between bipolar risk status and internalizing and externalizing problems. High-risk (n = 90) BD offspring and control (n = 56) offspring aged 12-21 years old, and their parents, completed questionnaires on family cohesion and offspring internalizing and externalizing problems. Offspring also completed a parental bonding questionnaire. Group differences were examined, followed by multi-level mediation analysis with maximum likelihood and robust standard errors. Both offspring and parents in the high-risk group reported higher levels of internalizing and externalizing problems than controls. According to offspring reports, high-risk status, lower maternal and paternal care in parental bonding, was independently associated with internalizing problems. Lower maternal care alone predicted externalizing problems. Family environment did not mediate the relationship between bipolar risk status, and offspring problems. Due to rates of missing data from parent reports of offspring psychopathology, mediation analysis was completed using offspring reports. The offspring-report data presented indicate that low parental warmth and connection were associated with internalizing and externalizing problems as an independent risk factor, in addition to bipolar risk status. The parent-child relationship therefore warrants attention as a potential target for prevention strategies with such families. Copyright © 2017 Elsevier B.V. All rights reserved.

This study tested a novel group-based, cognitive-behavioral intervention designed to reduce internalized weight stigma among individuals with obesity. A total of eight men and women with obesity who had experienced weight stigma and reported high levels of internalized weight stigma attended the Weight Bias Internalization and Stigma (BIAS) Program. The program provided eight weekly sessions of cognitive-behavioral treatment to cope with weight stigma. Participants completed questionnaires pre- and post-intervention, including the Weight Bias Internalization Scale (WBIS), Fat Phobia Scale, Weight Efficacy Life-Style Questionnaire (WEL), and Beck Depression Inventory-II (BDI-II). Six additional participants were included in a quasi-control group that received no intervention until after completing all study measures. Participants in the Weight BIAS Program reported significantly greater decreases in WBIS and Fat Phobia scores, and greater increases in WEL scores than participants in the quasi-control group (ps < .04). Changes in BDI-II scores did not differ between groups. Treatment-acceptability ratings were high among participants who received the intervention. Including cognitive-behavioral strategies to address weight stigma in weight management programs could potentially reduce internalized weight stigma and enhance treatment outcomes.

Remifentanil has been reported to cause post-anesthetic shivering (PAS). Higher doses of remifentanil reportedly induce more intense PAS. Tramadol, a synthetic opioid that acts at multiple sites, is considered to be an effective treatment for PAS, but the evidence for its therapeutic benefit after remifentanil anesthesia is limited. We investigated the effect of tramadol on the incidence of PAS after remifentanil anesthesia. Sixty-three patients who had undergone upper abdominal surgery under general anesthesia were studied retrospectively. Tramadol was administered at induction of anesthesia. The patients were divided into four groups: HT(+), high dose remifentanil (1-1.5 μg/kg/min) with tramadol; HT(-), high dose remifentanil without tramadol; LT(+), low dose remifentanil (0.15-0.25 μg/kg/min) with tramadol; and LT(-), low dose remifentanil without tramadol. We recorded perioperative changes in nasopharyngeal temperature and episodes of PAS on emergence from anesthesia. The incidences of PAS in both tramadol treatment groups were significantly lower than the groups that did not receive tramadol. Nasopharyngeal temperature after surgery fell significantly more from baseline in the tramadol treatment groups compared with the non-treatment groups. Tramadol administered at induction of anesthesia appears to suppress PAS following remifentanil anesthesia.

This study was performed to evaluate the relation between a stable personality trait, a mood state and immune response to an examination stress. A self-reported measure of emotional stability (BFQ-ES scale) was obtained in a sample (n = 39) randomly selected from 277 cadets; this personality trait was also investigated by completing a neuroticism scale (Eysenck personality inventory) and a trait-anxiety scale (STAI). Natural killer (NK) cell activity was measured at baseline, long before the examination time and the examination day. The state-anxiety scale evaluated the response to the stressful stimulus. Taking subjects all together, the academic task did not result in significant modification over baseline in NK cell activity. Subjects were then divided into three groups based on emotional stability and state-anxiety scores: high emotional stability/low anxiety, medium, and low emotional stability/high anxiety. Examination stress induced significant increases in NK cell activity in the high emotional stability/low anxiety group, no effect in the medium group, and significant decreases in the low emotional stability/high anxiety group. The repeated-measure ANOVA revealed a significant interaction of group x period (baseline vs. examination) for both lytic units and percent cytolysis. The results did not change after introducing coffee and smoking habits as covariates. Our findings suggest that the state-anxiety acts in concert with a stable personality trait to modulate NK response in healthy subjects exposed to a psychological naturalistic stress. The relation between anxiety and poor immune control has been already described, whereas the ability of emotional stability to associate with an immunoenhancement has not yet reported. The peculiarity of our population, a very homogeneous and healthy group for life style and habits, can have highlighted the role of emotional stability, and may account for the difference with other studies.

Nonsuicidal Self-Injury and Suicidal Behavior: A Latent Class Analysis among Young Adults

Hamza, Chloe A.; Willoughby, Teena

2013-01-01

Although there is a general consensus among researchers that engagement in nonsuicidal self-injury (NSSI) is associated with increased risk for suicidal behavior, little attention has been given to whether suicidal risk varies among individuals engaging in NSSI. To identify individuals with a history of NSSI who are most at risk for suicidal behavior, we examined individual variability in both NSSI and suicidal behavior among a sample of young adults with a history of NSSI (N = 439, Mage = 19.1). Participants completed self-report measures assessing NSSI, suicidal behavior, and psychosocial adjustment (e.g., depressive symptoms, daily hassles). We conducted a latent class analysis using several characteristics of NSSI and suicidal behaviors as class indicators. Three subgroups of individuals were identified: 1) an infrequent NSSI/not high risk for suicidal behavior group, 2) a frequent NSSI/not high risk for suicidal behavior group, and 3) a frequent NSSI/high risk for suicidal behavior group. Follow-up analyses indicated that individuals in the ‘frequent NSSI/high risk for suicidal behavior’ group met the clinical-cut off score for high suicidal risk and reported significantly greater levels of suicidal ideation, attempts, and risk for future suicidal behavior as compared to the other two classes. Thus, this study is the first to identity variability in suicidal risk among individuals engaging in frequent and multiple methods of NSSI. Class 3 was also differentiated by higher levels of psychosocial impairment relative to the other two classes, as well as a comparison group of non-injuring young adults. Results underscore the importance of assessing individual differences in NSSI characteristics, as well as psychosocial impairment, when assessing risk for suicidal behavior. PMID:23544113

This study examined the direct and indirect outcomes of a social skills group intervention for children with high functioning autism spectrum disorders and their parents. Thirty-five children and their parents participated in the program evaluation. Children and parents completed measures of child social skills and problem behaviors. Children reported on their self-concept, and parents reported on their psychological acceptance and empowerment. Results indicate significant increases in overall child social skills according to parent and child report, in child general self-worth, and in parent service empowerment and psychological acceptance. While past program evaluations of social skills groups highlight changes in social competence, taking a broader perspective on the types of positive outcomes suggests potential benefits for both child and parent.

Esophageal achalasia can be roughly divided into non-sigmoid and sigmoid types. Laparoscopic surgery has been reported to be less than optimally effective for sigmoid type. The aim of this study was to examine the impact of the esophageal flexion level on the clinical condition and surgical outcomes of patients with sigmoid esophageal achalasia. The subjects were 36 patients with sigmoid esophageal achalasia who had been observed for >1 year after surgery. The subjects were divided into sigmoid type (Sg) and advanced sigmoid type (aSg) groups based on the flexion level of the lower esophagus to compare their clinical parameters and surgical outcomes. The Sg and aSg groups included 26 (72%) and 10 subjects, respectively. There were no marked differences in the clinical parameters or surgical outcomes between the two groups. However, the clearance rate calculated using the timed barium esophagogram was lower in the aSg group than in the Sg group. No differences were found in the postoperative symptom scores between the two groups, and both reported a high level of satisfaction. Although laparoscopic surgery for symptoms of sigmoid esophageal achalasia was highly successful regardless of the flexion level, the improvement in esophageal clearance was lower when the flexion level was higher.

Although most women infected with HIV are intravenous drug users, some contact the virus through sexual contact with IV drug users. To reach at-risk women, public health officials must develop a range of prevention strategies. One approach, skills training, holds promise as a means of altering risk-related sexual behavior. In this study, 91 women methadone patients were pretested and randomly assigned to an information-only control control group or a skills-building intervention group. Skills-building intervention consisted of five sessions of small groups in which participants identified their own high risk sexual behaviors, discussed their negative associations with condoms, and practiced skills which involved asking partners to use condoms. Compared with members of the control group, respondents in the intervention group reported that they initiated discussion of sexual issues with their partners more frequently, felt more comfortable talking with them about safer sex, and reported using and carrying condoms more frequently. The high rates of attendance and program retention by skills-building participants suggest that such groups may be supportive and useful in the design of risk reduction and drug abuse treatment programs. The modest outcomes of this study underscore the difficulty of altering risk behavior but also serve as a basis for future AIDS prevention studies. PMID:1905051

The aim of the study was to determine the effects of high-flow and low-flow hemodialysis (HD), with simultaneous treatment with folic acid and vitamin B12, on total homocysteine (tHcy) concentration in plasma of dialyzed patients. The planned clinical observation included 46 patients of both sexes, aged 21-82, treated with bicarbonate dialysis for a mean of 4.7 years. The patients were divided into group A, subsequently dialyzed by use of high-flow polysulphonic membrane (AN 69ST, Nephral 300), and group B that continued to be dialyzed by use of low-flow diacetate membrane (Diacepal 14 and 16). The subjects in both groups received 30 mg of folic acid at the end of each dialysis (3 times a week), and 500 g of vitamin B12 at the end of every other dialysis. The method of stable isotopic dilution mass spectrometry was used to measure tHcy. Folic acid was determined by the test based on ion capture technology. Vitamin B12 was determined by MEIA. An increase in the concentration of tHcy was observed in 39/46 (85%) patients with a mean concentration of 24.76 +/- 11.04 micromol/L. The mean concentration of folic acid and vitamin B12 was within the normal limits. In the group dialyzed by high-flow dialyzer, the values of tHcy and folic acid decreased (18.74 +/- 2.95 micromol/L and 13.90 +/- 6.78 pmol/L) after hemodialysis, which was significant compared to the initial value (p<0.01 and p<0.05, respectively). At four weeks of treatment, tHcy concentration before HD showed a significant decrease both in the group dialyzed by high-flow dialyzer (15.10 +/- 4.26 mmol/L, p<0.01) and in the group dialyzed by low-flow dialyzer (12.54 +/- 3.87 micromol/L, p<0.01) compared to the measure before HD and before the treatment. There was no statistically significant difference (z -0.40, p>0.68) in the percentage of tHcy change between the group treated by high-flow dialyzer and the group treated by low-flow dialyzer in the measurements before HD and before the treatment with folic acid and vitamin B12, and after the treatment. There is a literature report on the concentration increase by 26 micromol/L, which is very similar to our result. The absence of long-term effect on predialysis concentration of tHcy in HD by high-flow membrane has also been described, because the decrease of tHcy is mantained until the uremic toxins, enzyme inhibitors that are necessary for the process of remethylation of Hcy, accumulated again. During high-flow HD, the folic acid concentration decreased by 23.05% on an average, consistent with other literature reports. Some reports support our observation that the dosage of folic acid required for tHcy decrease is 15-30 mg, and that the dosage higher than 60 mg does not significantly decrease tHcy concentration. Our study confirmed the reported observations that treatment with folic acid and vitamin B12 rather than high-flow dialyzer contributes to tHcy decrease. The study confirmed the high prevalence of hyperhomocysteinemia in patients on dialysis. The treatment with folic acid and vitamin B12 results in a significant decrease of tHcy. After individual HD by high-flow dialyzer, there is a significant, but temporary decrease of tHcy concentration in plasma. There is no significant difference in the efficiency on pre-dialysis tHcy concentration between the high-flow and low-flow dialyzer membrane. Because of the atherogenic effect of hyperhomocysteinemia, the treatment with folic acid and vitamin B12 should be accepted as an options to lower the risk factors for the rapid atherosclerosis in patients on dialysis, thus reducing the occurrence and fatality of cardiovascular diseases.

OBJECTIVE To describe the occurrence of common medical and psychological conditions in individuals with Down syndrome during their life span, and to measure the use of the Down Syndrome Medical Interest Group’s health care guidelines by family physicians across Canada, as reported by parents or caregivers. METHODS The Down Syndrome Research Foundation sent a questionnaire to 314 families across Canada who were part of the Canadian Voluntary Registry on Down Syndrome. This questionnaire was designed to collect information from parents about physical examinations, laboratory tests, referrals and discussions with family physicians that are listed in the health care guidelines. RESULTS Two hundred twenty-three families responded to the survey. The highest response rates were in families with children in the five- to 12-year-old age range (41.7%) and the 13- to 18-year-old age range (19.7%). The most common medical conditions reported were visual, hearing and cardiac related. A high percentage of sleep-, gastrointestinal- and thyroid-related conditions were also reported. In the adult group (ie, 30 years of age and older), there was a high proportion of depression and/or anxiety disorders reported. The percentage of those reporting physical examinations and medical referrals by family physicians were highest in the five- to 12-year-old age range and dropped below 50% in those aged 19 years and older. In the one- to four-year-old and five- to 12-year-old age groups, the percentages of those with Down syndrome referred for hearing tests and celiac screens were reported to be below 30%. The percentages of those reporting discussions on behavioural issues were below 50% in all age groups. CONCLUSIONS Physical examinations, as per the recommended guidelines, were followed only in the five- to 12-year-old age group. Many of the recommendations regarding discussion of behavioural problems, transition planning, diet, exercise and issues around puberty or sexual health were followed infrequently in all age groups. Further physician education about the guidelines is necessary. PMID:19030356

The purpose of this study was to compare characteristics of youth who participate in the choking game alone versus those who participate in a group. Lifetime prevalence estimates were obtained from the 2011 (n = 5682) and 2013 (n = 15 150) Oregon Healthy Teens survey. The 2011 and 2013 data sets were merged (N = 20 832) to compare youth who participate alone versus those who participate in a group in the choking game. Multivariate modeling was conducted to examine individual characteristics of young people who engaged in the choking game alone versus those who engaged in the game in a group. In 2011, 3.8% of eighth-grade participants reported a lifetime prevalence of choking game participation; 3.7% reported lifetime prevalence of participation in 2013. In the merged 2011/2013 data set, 17.6% (n = 93) of choking game participants indicated that they had participated alone. Compared with those who reported participating in a group, youth who participated alone had significantly higher rates of suicide contemplation (odds ratio: 4.58; P < .001) and poor mental health (odds ratio: 2.13; P < .05). Youth who participate alone in the choking game are a particularly high risk group, exhibiting substantially higher rates of suicidal ideation and poorer mental health compared with youth who participate in the choking game in a group. Adolescent health care providers should be aware of these associations, assess whether prevention messaging is appropriate, and be prepared to explain the high risks of morbidity and mortality associated with participation.

Patterns of adjustment for youth victimized by peers vary depending on whether youth are identified as victims through self-reports, peer-reports, or both. In order to provide more targeted strategies that may help mitigate negative consequences associated with specific victimization groups, more information is needed about how these youth perceive their school ecology (bullying and academic ecology), their feelings of school belonging, and their valuing of school. Based on the convergence of self- and peer-reports of victimization, we identified four victim groups from a sample of students in 5th grade classrooms (N = 1360; 52.8% girls, 53.1% White, 34.6% Black or Hispanic, 12.2% Native American, Asian, or other) using Latent Profile Analysis (LPA): convergent victims (high self- and peer-reports), self-identified victims (high self-, low peer-reports), peer-identified victims (low self-, high peer-reports), and nonvictims (low self- and peer-reports). Convergent victims' perceptions were similar to nonvictims with key differences being convergent victims' greater willingness to protect peers being bullied but lower feelings of school belonging compared to nonvictims. Peer-identified and self-identified victims perceived differences in the bullying and academic ecology including peer-identified victims' greater willingness to protect peers and expectations for more peers to encourage bulling against them compared to self-identified victims. However, both peer- and self-identified victims perceived greater emotional risk of participating in class and had lower feelings of school belonging compared to nonvictims. Implications for supporting youth with divergent self- and peer-reported victimization status as they transition to middle school are discussed.
Upgrading Existing Buildings to Universal Design. What Cost-Benefit Analyses Can Tell Us.

Aslaksen, Finn

2016-01-01

This article is based on a project aimed at finding the benefits of different measures to upgrade existing public buildings and outdoor areas to be accessible for all. The study was initiated by The Ministry of Children and Equality. The ministry asked for a study of benefits based on a stated preferences (SP) method and an easy-to-complete calculation tool for CBA. In the project 18 commonly used measures and their typical costs were identified. The benefits of each measure were analysed in a stated preference study. The SP analyses included 9 multiple choices in 4 different sequences in an Internet based survey with 800 respondents. The project concluded that it is possible to use stated preferences survey to identify the respondent's valuation of measures to improve accessibility in existing buildings. Some of the measures have a high cost-/benefit ratio. The project report including the calculation manual is based on the average valuation for each measure. But in the background analyses (not referred in the report) there are also some analyses of valuations for target groups for the various measures. The target groups were defined for each measure based on information about the respondents' abilities and use of technical aids. The analyses presented in this paper indicate how valuation varies between the target groups and the average population. This is named the measures profile. Some measures have benefits for the target group that are only twice as high as for the average citizen while another type of measures has high benefits only the target group. The first type which has a wide profile often has high overall socioeconomic benefits, while the last group with a narrow profile more often has low overall socioeconomic benefits, but may be very important for certain user groups and therefore essential for the elimination of discrimination and exclusion of those groups.

Objective Nonadherence reduces glaucoma treatment efficacy. Motivational interviewing (MI) is a well-studied adherence intervention, but has not been tested in glaucoma. Reminder interventions also may improve adherence. Design 201 patients with glaucoma or ocular hypertension were urn-randomized to receive MI delivered by an ophthalmic technician (OT), usual care, or a minimal behavioral intervention (reminder calls). Main Outcome Measures Outcomes included electronic monitoring with Medication Event Monitoring System (MEMS) bottles, two self-report adherence measures, patient satisfaction, and clinical outcomes. Multilevel modeling was used to test differences in MEMS results by group over time; ANCOVA was used to compare groups on other measures. Results Reminder calls increased adherence compared to usual care based on MEMS, p = .005, and self-report, p = .04. MI had a nonsignificant effect but produced higher satisfaction than reminder calls, p = .007. Treatment fidelity was high on most measures, with observable differences in behavior between groups. All groups had high baseline adherence that limited opportunities for change. Conclusion Reminder calls, but not MI, led to better adherence than usual care. Although a large literature supports MI, reminder calls might be a cost-effective intervention for patients with high baseline adherence. Replication is needed with less adherent participants.

This study examined the influence of safety climate and psychosocial work environment on the reported fatigue of seafarers working in the offshore oil and gas re-supply industry (n = 402). We found that seafarers who reported high psychological demands and perceived the organisational-level safety climate negatively,reported significantly more mental fatigue, physical fatigue, and lack of energy. In addition, seafarers who reported having high levels of job control reported being significantly less mentally fatigued. We also found some combined effects of safety climate and shift arrangement. Organisational-level safety climate did not influence the levels of physical fatigue in seafarers working on the night shift. On the contrary, seafarers working during the days reported to be more physically fatigued when they perceived the organisational-level climate to be negative compared with the positive. The opposite effect was found for group-level safety climate: seafarers working during the nights reported to be more physically fatigued when they perceived the group-level climate to be negative compared with the positive. The results from this study point to the importance of taking into consideration aspects of the psychosocial work environment and safety climate,and their potential impact on fatigue and safety in the maritime organisations.

This study characterizes hypnagogic hallucinations reported during a polygraphically recorded 90-min daytime nap following or preceding practice of the computer game Tetris. In the experimental group (N = 16), participants played Tetris in the morning for 2 h during three consecutive days, while in a first control group (N = 13, controlling the effect of experience) participants did not play any game, and in a second control group (N = 14, controlling the effect of anticipation) participants played Tetris after the nap. During afternoon naps, participants were repetitively awakened 15, 45, 75, 120 or 180 s after the onset of S1, and were asked to report their mental content. Reports content was scored by three judges (inter-rater reliability 85%). In the experimental group, 48 out of 485 (10%) sleep-onset reports were Tetris-related. They mostly consisted of images and sounds with very little emotional content. They exactly reproduced Tetris elements or mixed them with other mnemonic components. By contrast, in the first control group, only one report out of 107 was scored as Tetris-related (1%), and in the second control group only three reports out of 112 were scored as Tetris-related (3%; between-groups comparison; P = 0.006). Hypnagogic hallucinations were more consistently induced by experience than by anticipation (P = 0.039), and they were predominantly observed during the transition of wakefulness to sleep. The observed attributes of experience-related hypnagogic hallucinations are consistent with the particular organization of regional brain activity at sleep onset, characterized by high activity in sensory cortices and in the default-mode network. © 2011 European Sleep Research Society.
Sleep complaints affecting school performance at different educational levels.

The clear association between reports of sleep disturbance and poor school performance has been documented for sleepy adolescents. This study extends that research to students outside the adolescent age grouping in an associated school setting (98 middle school students, 67 high school students, and 64 college students). Reported restless legs and periodic limb movements are significantly associated with lower GPA's in junior high students. Consistent with previous studies, daytime sleepiness was the sleep variable most likely to negatively affects high school students. Sleep onset and maintenance insomnia were the reported sleep variables significantly correlated with poorer school performance in college students. This study indicates that different sleep disorder variables negatively affect performance at different age and educational levels.

The current study employed a quasi-experimental design using both intent-to-treat and protocol adherence analysis of 155 moderate- to high-risk juvenile offenders to evaluate the effectiveness of Parenting with Love and Limits® (PLL), an integrative group and family therapy approach. Youth completing PLL had significantly lower rates of recidivism than the comparison group. Parents also reported statistically significant improvements in youth behavior. Lengths of service were also significantly shorter for the treatment sample than the matched comparison group by an average of 4 months. This study contributes to the literature by suggesting that intensive community-based combined family and group treatment is effective in curbing recidivism among high-risk juveniles. © 2015 Family Process Institute.

Anger management programmes for offenders typically aim to improve the management of emotion associated with aggressive and antisocial behaviour. Such programmes have been quite extensively evaluated in prison and probation settings, but there is less published research in forensic mental health settings. This study aimed to evaluate anger management groups in a high-security hospital. Eighty-six patients were referred for a 20-session anger management intervention. Outcomes were self-reported experiences of anger and changes in institutionally documented incidents of aggression. Incident rates were retrospectively reviewed for all group graduates, where data were available, including a comparison group of graduates who acted as their own controls. Group graduates reported sustained reductions in feelings of anger and positive changes in their use of aggression in reaction to provocation. Some reduction in incidents of physical aggression was noted when group completers were compared with non-completers. Incidents of verbal aggression were observed to increase for graduates. There was also a trend towards improvement when treated men were compared with men on the waiting list. Our findings contribute to the growing evidence for anger management groups for aggressive men, although the low-base rate of incidents, typical of such a containing and therapeutic hospital setting, rendered the analysis of behavioural outcomes difficult. Anger management sessions for male forensic psychiatric patients can be effective in reducing incidents of physical aggression in response to provocation. Evaluation of treatments for anger is particularly difficult in secure and protective settings, where the aim is to keep incidents of actual physical aggression to a minimum. Further research of this kind is needed to test the value of self-reported reduction in angry feelings as an indicator of clinically useful progress. Copyright © 2013 John Wiley & Sons, Ltd.

Nonalcoholic steatohepatitis (NASH) and nonalcoholic fatty liver disease are increasing in adults and are likely to be increasing in children. Both conditions are hepatic manifestations of metabolic syndrome. Experimental animals fed fructose-enriched diets are widely recognized as good models for metabolic syndrome. However, few reports have described the hepatic pathology of these experimental animals. In this study, 5-wk-old Wistar specific pathogen-free rats, which are a normal strain, were fed experimental diets for 5 wk. We then evaluated the degree of steatohepatitis. The 5 diet groups were as follows: cornstarch (70% wt:wt) [control (C)], high-fructose (70%) (HFr), high-sucrose (70%) (HS), high-fat (15%) (HF), and high-fat (15%) high-fructose (50%) (HFHFr) diets. The macrovesicular steatosis grade, liver:body weight ratio, and hepatic triglyceride concentration were significantly higher in the HFr group than in the other 4 groups. However, the HFr group had a significantly lower ratio of epididymal white fat:body weight than the other 4 groups and had a lower final body weight than the HF and HFHFr groups. The HF group had a greater final body weight than the C, HFr, and HS groups, but no macrovesicular steatosis was observed. The HFr group had a significantly higher grade of lobular inflammation than the other 4 groups. The distribution of lobular inflammation was predominant over portal inflammation, which is consistent with human NASH. In conclusion, rats fed fructose-enriched diets are a better model for NASH than rats fed fat-enriched diets.
Experiential avoidance in the vulnerability to depression among adolescent females.

Although various mechanisms in the maternal transmission of Major Depressive Disorder (MDD) have been investigated, it is unknown whether experiential avoidance (EA) is a vulnerability factor in the development of depression or a consequence of the illness. The present study utilized a high-risk design to determine if EA indeed poses vulnerability to adolescent MDD. Secondly, we examined the means by which adolescent EA may come to pose vulnerability, namely that it explains the relation between maternal EA and adolescent depressive symptoms. One-hundred and forty-six biological mother/adolescent daughter dyads comprised three diagnostic groups: mothers with a history of MDD and their depressed daughters (MDD; n=21), mothers with a history of MDD and their never-depressed daughters (high-risk, HR; n=69), and healthy controls (HCs; n=56). Groups differed on daughter EA such that the MDD group reported greater EA than the HR group, which in turn reported greater EA than HCs. Daughter EA mediated the relation between maternal EA and daughter depressive symptoms after controlling for maternal depressive symptoms. Strengths aside, this study included a relatively small group of depressed mother-daughter dyads and relied on cross-sectional self-report data. EA appears to serve as a vulnerability factor for adolescent MDD, and the mechanistic role of daughter EA highlights the significance of intergenerational EA in the maternal transmission of depression. Therapeutic approaches may therefore consider reducing the transmission of EA from mothers to daughters. Copyright © 2016 Elsevier B.V. All rights reserved.

BACKGROUND We examined the differential impact of a well-established human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) curriculum, Be Proud! Be Responsible!, when taught by school nurses and health education classroom teachers within a high school curricula. METHODS Group-randomized intervention study of 1357 ninth and tenth grade students in 10 schools. Twenty-seven facilitators (6 nurses, 21 teachers) provided programming; nurse-led classrooms were randomly assigned. RESULTS Students taught by teachers were more likely to report their instructor to be prepared, comfortable with the material, and challenged them to think about their health than students taught by a school nurse. Both groups reported significant improvements in HIV/STI/condom knowledge immediately following the intervention, compared to controls. Yet, those taught by school nurses reported significant and sustained changes (up to 12 months after intervention) in attitudes, beliefs, and efficacy, whereas those taught by health education teachers reported far fewer changes, with sustained improvement in condom knowledge only. CONCLUSIONS Both classroom teachers and school nurses are effective in conveying reproductive health information to high school students; however, teaching the technical (eg, condom use) and interpersonal (eg, negotiation) skills needed to reduce high-risk sexual behavior may require a unique set of skills and experiences that health education teachers may not typically have.

Two-dimensional hexagonal materials such as graphene and silicene have highly symmetric crystal structures and Dirac cones at the K point, which induce novel electronic properties. In this report, we calculate their electronic structures by using density functional theory and analyze their band structures on the basis of the group theory. Dirac cones frequently appear when the symmetry at the K point is high; thus, two-dimensional irreducible representations are included. We discuss the relationship between symmetry and the appearance of the Dirac cone.
Age Group Comparisons of TENS Response Among Individuals With Chronic Axial Low Back Pain.

2015-12-01

Chronic low back pain (CLBP) is a highly prevalent and disabling musculoskeletal pain condition among older adults. Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat CLBP, however response to TENS in older adults compared with younger adults is untested. In a dose-response study stratified by age, 60 participants with axial CLBP (20 young, 20 middle-aged, 20 older) received four 20-minute sessions of high-frequency high-intensity TENS over a 2- to 3-week period in a laboratory-controlled setting. Experimental measures of pain sensitivity (mechanical pressure pain detection threshold) and central pain excitability (phasic heat temporal summation and heat aftersensations) were assessed before and after TENS. Episodic or immediate axial CLBP relief was assessed after TENS via measures of resting pain, movement-evoked-pain, and self-reported disability. Cumulative or prolonged axial CLBP relief was assessed by comparing daily pain reports across sessions. Independent of age, individuals experienced episodic increase in the pressure pain detection threshold and reduction in aftersensation after TENS application. Similarly, all groups, on average, experienced episodic axial CLBP relief via improved resting pain, movement-evoked pain, and disability report. Under this design, no cumulative effect was observed as daily pain did not improve for any age group across the 4 sessions. However, older adults received higher TENS amplitude across all sessions to achieve TENS responses similar to those in younger adults. These findings suggest that older adults experience similar episodic axial CLBP relief to that of younger individuals after high-frequency, high-intensity TENS when higher dose parameters are used. This study examined age group differences in experimental and axial CLBP response to TENS, delivered under the current recommended parameters of strong, but tolerable amplitude. Older adults had comparable TENS response although at higher TENS amplitude than younger adults, which may have important mechanistic and clinical implications.

Objectives Prior research has shown that Dutch general practitioners (GPs) do not always offer HIV testing and the number of undiagnosed HIV patients remains high. We aimed to further investigate the frequency and reasons for (not) testing for HIV and the contribution of GPs to the diagnosis of HIV infections in the Netherlands. Design Observational study. Setting (1) Dutch primary care network of 42–45 sentinel practices where report forms during sexually transmitted infection (STI)-related consultations were routinely collected, 2008–2013. (2) Dutch observational cohort with medical data of HIV-positive patients in HIV care, 2008–2013. Outcome measures The proportion of STI-related consultations in patients from high-risk groups tested for HIV, with additional information requested from GPs on HIV testing preconsultation or postconsultation for whom HIV testing was indicated, but not performed. Next, information was collected on the profile of HIV-positive patients entering specialised HIV care following diagnosis by GPs. Results Initially, an HIV test was reported (360/907) in 40% of STI-related consultations in high-risk groups. Additionally, in 26% of consultations an HIV test had been performed in previous or follow-up consultations or at different STI-care facilities. The main reasons for not testing were perceived insignificant risk; ‘too’ recent risk according to GPs or the reluctance of patients. The initiative of the patient was a strong determinant for HIV testing. GPs diagnosed about one third of all newly found cases of HIV. Compared with STI clinics, HIV-positive patients diagnosed in general practice were more likely to be older, female, heterosexual male or sub-Saharan African. Conclusions In one-third of the STI-related consultations of persons from high-risk groups, no HIV test was performed in primary care, which is lower than previously reported. Risk-based testing has intrinsic limitations and implementation of new additional strategies in primary care is warranted. PMID:26801464

We examined the relationship between anxiety sensitivity (AS) and autonomic nervous system responses (ANS) during the cold pressor test (CPT). Seventy-four university students participated and were divided into low-AS (M=9.06, SD=3.97) and high-AS groups (M=28.68, SD=6.63) based on AS Index scores (n's=36 and 38, respectively). The study included three phases: Rest, CPT, and Recovery. We measured the psychological variables (fear of pain and subjective pain) at pre- and post-CPT. ANS response data were collected during each phase. Fear of pain was experienced more strongly in the high-AS group (M=4.74, SD=3.25) relative to the low-AS group (M=2.72, SD=2.31), and subjective pain was also stronger in the high-AS group (M=3.08, SD=1.91) relative to the low-AS group (M=2.47, SD=1.00) in post-CPT. While parasympathetic nervous system (PNS) responses did not differ between the two groups during the CPT, the high AS-group demonstrated lower PNS activity during the Recovery phase. The high-AS group reported significantly more anticipatory fear and pain prior to the CPT, which appeared to aggravate subjective pain experiences. Furthermore, for individuals with anxiety sensitivity, ANS reactivity may be the mechanism underlying the relationship between negative affect and subjective pain. Copyright © 2017.

Group formation of rhesus monkeys, often leads to victims of repeated attacks by the high ranking animal. We reported a case of an injured middle ranking monkey from repetitive and persistent aggression. 4-male rhesus group was formed by a rapid group formation strategy 2 years ago. One monkey in the group suddenly showed depressive and reluctant movement. Physical examination revealed multiple bite wounds and scars in the dorsal skin. Overall increased opacity of the dorsal soft tissue and some free air was observed on radiographic examination. An unidentified anaerobic gram negative bacillus was isolated from the bacterial culture. Reconstructive surgery was performed and in consequence, the wound was clearly reconstructed one week later. Eventually, the afflicted monkey was separated and housed apart from the hierarchical group. This case report indicate that group formation in rhesus monkeys is essentially required sufficient time and stages, as well as more attention and a progressive contact program to reduce animal stress and fatal accidents.

Alpha and beta-glucoisosaccharinic acids ((2S,4S)-2,4,5-trihydroxy-2-(hydroxymethyl)pentanoic acid and (2R,4S)-2,4,5-trihydroxy-2-(hydroxymethyl)pentanoic acid) which are produced when cellulosic materials are treated with aqueous alkali are potentially valuable platform chemicals. Their highly functionalised carbon skeleton, with fixed chirality at C-2 and C-4, makes them ideal starting materials for use in synthesis. In order to assess the potential of these saccharinic acids as platform chemicals we have explored the protecting group chemistry of the lactone form of alpha-glucoisosaccharinic acid (α-GISAL). We report here the use of single and multiple step reaction pathways leading to the regioselective protection of the three different hydroxyl groups of α-GISAL. We report strategies for protecting the three different hydroxyl groups individually or in pairs. We also report the synthesis of a range of tri-O-protected α-GISAL derivatives where a number of the products contain orthogonal protecting groups. Copyright © 2017 Elsevier Ltd. All rights reserved.

An interactive computer program (Personal Education Program [PEP]) designed for the learning styles and psychomotor skills of older adults was used to teach older adults about potential drug interactions that can result from self-medication with over-the-counter (OTC) agents and alcohol. Subjects used the PEP on notebook computers equipped with infrared sensitive touchscreens. Subjects were recruited from senior centers. Those who met age, vision, literacy, independence, and medication use criteria were randomly assigned to one of three groups: (1) PEP plus information booklet; (2) information booklet only; or (3) control. A repeated measures (three time periods 2 weeks apart), three-group design was used. Users of PEP had significantly greater knowledge and self-efficacy scores than both the conventional and control groups at all three time points. The PEP group reported fewer adverse self-medication behaviors over time. Reported self-medication behaviors did not change over time for either the conventional or control groups. Subjects indicated a high degree of satisfaction with the PEP and reported their intent to make specific changes in self-medication behaviors.

This pilot study examines the feasibility, acceptability, and potential effectiveness of delivering an intensive weekend group treatment for panic disorder (PD) to Veterans returning from deployments to Iraq and Afghanistan with co-occurring posttraumatic stress disorder (PTSD). The treatment program lasted 6h each day and was delivered by two experienced therapists. Patients received core components of panic treatment, including psychoeducation, cognitive restructuring, and interoceptive exposure. The interoceptive exposure exercises directly targeted anxiety sensitivity, a psychological construct also implicated in the maintenance of PTSD. Eighty-nine percent of patients who expressed interest in the treatment attended a baseline evaluation, and 63% of those who were study eligible initiated treatment. Treatment retention was high, with all 10 patients who initiated treatment completing the program. Veterans reported finding the treatment and delivery format highly acceptable and reported high levels of satisfaction. Panic symptoms improved significantly following the treatment and were maintained at a 7-month follow-up, with 71.4% of the sample reporting being panic free. Co-occurring PTSD symptoms also improved along with symptoms of anxiety and depression. Preliminary findings suggest that brief and intensive group treatments for PD/PTSD are a promising method of delivering cognitive behavioral therapy that may rapidly improve symptoms. This innovative treatment delivery format also may be a cost-effective way of increasing treatment engagement through increased access to quality care. Published by Elsevier Ltd.

The cross-coupling reaction of aryl bromides and iodides with aliphatic and aromatic thiols catalyzed by palladium complexes of the bisphosphine ligand CyPF-tBu (1) is reported. Reactions occur in excellent yields, broad scope, high tolerance of functional groups and with turnover numbers that exceed those of previous catalysts by two or three orders of magnitude. These couplings of bromo- and iodoarenes are more efficient than the corresponding reactions of chloroarenes and could be conducted with less catalyst loading and/or milder reaction conditions. Consequently, limitations regarding scope and functional group tolerance previously reported in the coupling of aryl chlorides are now overcome. PMID:19154131

The consumption of caffeine has become a growing concern, partially because of the withdrawal properties of the drug. The current study examined personality correlates of caffeine consumption and dependence in 60 university students. Self-report and behavioral measures of sensation seeking, impulsivity, and risk taking were administered to 2 groups, identified as caffeine dependent-high consuming or caffeine nondependent-low consuming. Scores on self-report measures of sensation seeking and impulsivity were related to group status, and only sensation seeking evidenced a significant relationship with group status when both variables were considered in a regression analysis. Implications of these findings and future directions are discussed. ((c) 2005 APA, all rights reserved).

Medical innovation in developed countries has been linked to burden of disease, with more innovation in areas representing greater investment return. This study used horizon scanning or early awareness and alert activity as a novel measure of innovation to determine whether new and emerging health technologies reported by international horizon scanning agencies reflected diseases constituting the greatest burden. This was a retrospective observational study of the 20 member agencies of EuroScan (the International Information Network on New and Emerging Health Technologies), representing 17 developed countries. Burden of disease was defined as disability-adjusted life-years, taken from the 2004 World Health Organization Global Burden of Disease estimates. This analysis focused on 102 specific diseases within 21 broader groups. Horizon scanning output was measured as the number of technologies reported by EuroScan member agencies between 2000 and 2009. At best there was a weak association between innovation and burden of disease. An apparent high-level association was dependent on just three high-prevalence disease groups: malignant neoplasms, neuropsychiatric conditions, and cardiovascular disease. Disaggregating broader groups into specific diseases further weakened the association. Innovation is disproportionately strong in cancer and nonischemic heart disease and disproportionately weak in mental health. Innovations reported by early awareness and alert systems do not always reflect conditions accounting for the highest morbidity and mortality. The results do not support previous reports of a positive relationship between burden of disease and innovation, but accord with evidence of notable discrepancies among key groups. Factors other than disease burden drive innovation. Copyright Â© 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc. All rights reserved.

Effort-Reward Imbalance and Work Productivity Among Hotel Housekeeping Employees: A Pilot Study.

PubMed

Rosemberg, Marie-Anne S; Li, Yang

2018-03-01

This study explored the relationship between effort-reward imbalance (ERI) at work and work productivity among hotel housekeepers. A community-based approach was used to recruit 23 hotel housekeepers who completed the ERI and Work Performance Questionnaires. Work productivity was determined by combining self-report absenteeism and presenteeism. More than 40% of the participants reported high ERI (ERI >1). Also, 59.1% reported low work productivity. Interestingly, despite the individualized high reports of ERI and low work productivity, correlation analysis showed that high ERI was correlated with high presenteeism and work productivity as a whole. This is the first study to explore work productivity among this worker group. Despite the small sample size and the cross-sectional nature of the study, this study points to the need for organization-based interventions to not only improve employee health but also their work productivity.

Refugees all over the world are facing several health-related problems. Chronic diseases among Syrian refugees in Jordan are high. The Home Medication Management Review (HMMR) service could be ideal to optimize refugees' health management. To assess the impact of the HMMR service on the type and frequency of Treatment Related Problems (TRPs) among Syrian refugees living in Jordan. This prospective randomized single blinded intervention-control study was conducted in three main cities in Jordan, between May and October 2016. Syrian refugees with chronic conditions were recruited and randomized into intervention and control groups. The HMMR service was conducted for all patients to identify TRPs at baseline. Data were collected via two home visits for all study participants. Clinical pharmacist's recommendations were written in a letter format to the physicians managing the patients in the intervention group only. Physicians' approved recommendations were conveyed to the patients via the pharmacist. Interventions at the patient level were delivered by the pharmacist directly. Patients were reassessed for their TRPs and satisfaction 3 months after baseline. Syrian refugees (n = 106) were recruited with no significant differences between the intervention (n = 53) and control groups (n = 53). A total of 1141 TRPs were identified for both groups at baseline, with a mean number of 10.8 ± 4.2 TRPs per patient. At follow-up, there was a significant decrease in the number of TRPs among the intervention group (P < 0.001, paired sample t-test) but not among the control group (P = 0.116). Physicians' approval rate of the pharmacist's recommendations was high (82.9%), and more than 70.0% of refugees in the intervention group reported high satisfaction with the HMMR service. Identified TRPs are high amongst Syrian refugees living in Jordan. The HMMR service significantly reduced the number of TRPs, and was highly accepted by the physicians. Refugees reported high satisfaction with this service. Copyright © 2018. Published by Elsevier Inc.
Fathers' involvement in preschool programs for children with and without hearing loss.

Ingber, Sara; Most, Tova

2012-01-01

The authors compared the involvement in children's development and education of 38 fathers of preschoolers with hearing loss to the involvement of a matched group of 36 fathers of preschoolers with normal hearing, examining correlations between child, father, and family characteristics. Fathers completed self-reports regarding their parental involvement and parenting self-efficacy and reported on their family cohesion and adaptability. Mothers also reported on their husbands' involvement. Similarly high levels of involvement on the part of both groups of fathers were found. Involvement correlated positively with fathers' self-reported parenting self-efficacy, family cohesion, and adaptability, and mother-reported paternal involvement. Implications for professionals and mothers are discussed, including the need to encourage mothers' support for their husbands' involvement and to empower fathers' sense of competency in order to increase their involvement.
Male and female adolescents' perceived interpersonal communication skills according to history of sexual coercion.

Anderson, V; Reis, J; Stephens, Y

1997-01-01

This report summarizes the experience of 61 female adolescents recruited through a private adolescent family planning clinic, and 183 9th through 12th-grade adolescents recruited from a private suburban high school regarding their experiences with dating relationships, sexual communication skills, and psychological status. The samples were predominantly white and middle to upper income. Perceptions of interpersonal communication skills were analyzed according to gender, clinic versus school, and history of sexual coercion. The adolescents were generally confident that they could assert their own preferences and stand up to other regarding sexual issues with the exception of the small group of high school males reporting having had experienced sexual coercion. This group (N = 20) expressed difficulty in talking to their partners about safer sex, getting their partner(s) to listen to them, or turning down alcohol or drugs prior to having sex. These boys were also more likely to report missing classes or having other kinds of trouble with school, to be concerned about use of alcohol and drugs, and about feeling unpopular. None of the female groups had this profile of communication and emotional problems. Implications for preventive education programming on interpersonal skills and sexuality are considered.
Anesthetic depth and long-term survival: an update.

PubMed

Leslie, Kate; Short, Timothy G

2016-02-01

The purpose of this paper is to review the current evidence relating anesthetic depth to long-term survival after surgery. Using PubMed as the principal source, this review included published studies in all languages comparing mortality in patients with low- and high-processed electro-encephalo-graphic index values. All published studies used the bispectral index (BIS) monitor to measure anesthetic depth. The majority of the published observational studies were post hoc analyses of studies undertaken for other purposes. Most of these studies report a statistically significant association between deep general anesthesia (i.e., BIS values < 45) and death. Some studies also suggest an association between deep general anesthesia and myocardial infarction or postoperative cognitive decline. The combination of low BIS values and low delivered anesthetic concentrations (thus defining increased anesthetic sensitivity) may identify patients at particularly high risk. One of the three available randomized controlled trials reports worse outcomes in the BIS = 50 group compared with the BIS > 80 group, and two report no difference in mortality between the BIS = 35 and BIS = 50-55 groups. The available evidence on anesthetic depth and long-term survival is inconclusive. Randomized controlled trials with carefully controlled arterial blood pressure are required.
Cognitive performance, symptoms and counter-regulation during hypoglycaemia in patients with type 1 diabetes and high or low renin-angiotensin system activity.

High basal renin-angiotensin system (RAS) activity is associated with increased risk of severe hypoglycaemia in type 1 diabetes. We tested whether this might be explained by more pronounced cognitive dysfunction during hypoglycaemia in patients with high RAS activity than in patients with low RAS activity. Nine patients with type 1 diabetes and high and nine with low RAS activity were subjected to hypoglycaemia and euglycaemia in a cross-over study using an intravenous insulin infusion protocol. Cognitive function, electroencephalography, auditory evoked potentials and hypoglycaemic symptoms were recorded. At a hypoglycaemic nadir of 2.2 (SD 0.3) mmol/L the high RAS group displayed significant deterioration in cognitive performance during hypoglycaemia in the three most complex reaction time tasks. In the low RAS group, hypoglycaemia led to cognitive dysfunction in only one reaction time task. The high RAS group reported lower symptom scores during hypoglycaemia than the low RAS group, suggesting poorer hypoglycaemia awareness. High RAS activity is associated with increased cognitive dysfunction and blunted symptoms during mild hypoglycaemia compared to low RAS activity. This may explain why high RAS activity is a risk factor for severe hypoglycaemia in type 1 diabetes.

As jet fuel is a common occupational exposure among military and civilian populations, this study was conducted to characterize jet fuel (JP8) exposure among active duty U.S. Air Force personnel. Personnel (n = 24) were divided a priori into high, moderate, and low exposure groups. Questionnaires and personal air samples (breathing zone) were collected from each worker over 3 consecutive days (72 worker-days) and analyzed for total hydrocarbons (THC), benzene, toluene, ethylbenzene, xylenes, and naphthalene. Air samples were collected from inside the fuel tank and analyzed for the same analytes. Linear mixed-effects models were used to evaluate the exposure data. Our results show that the correlation of THC (a measure of overall JP8 inhalation exposure) with all other analytes was moderate to strong in the a priori high and moderate exposure groups combined. Inhalation exposure to all analytes varied significantly by self-reported JP8 exposure (THC levels higher among workers reporting JP8 exposure), a priori exposure group (THC levels in high group > moderate group > low group), and more specific job task groupings (THC levels among workers in fuel systems hangar group > refueling maintenance group > fuel systems office group > fuel handling group > clinic group), with task groupings explaining the most between-worker variability. Among highly exposed workers, statistically significant job task-related predictors of inhalation exposure to THC indicated that increased time in the hangar, working close to the fuel tank (inside > less than 25 ft > greater than 25 ft), primary job (entrant > attendant/runner/fireguard > outside hangar), and performing various tasks near the fuel tank, such as searching for a leak, resulted in higher JP8 exposure. This study shows that while a priori exposure groups were useful in distinguishing JP8 exposure levels, job task-based categories should be considered in epidemiologic study designs to improve exposure classification. Finally, the strong correlation of THC with naphthalene suggests that naphthalene may be an appropriate surrogate of JP8 exposure. [Supplementary materials are available for this article.

2018-05-01

The current study used latent class analysis to uncover groups of youths with specific abuse (physical, emotional, and sexual) profiles in and outside the family, and identify how membership in each abuse group is associated with behavioral outcomes. Data were collected among a sample of male (n = 662; M age  = 13.02 years) and female (n = 689; M age  = 12.95 years) children and adolescents (9-17 years old) from Barbados and Grenada. Self-report surveys were completed by participants in school settings. Three latent classes of child abuse were distinguished among boys, including 'low abuse' (39.2% of the sample), 'physical and emotional abuse high outside/medium in the family' (43.2%), and 'high overall abuse' (17.6%). Among girls, four unique classes were recovered: 'low abuse' (40.7%), 'high physical and emotional abuse outside the family' (7.6%), 'high emotional and moderate physical abuse' (33.9%), and 'high overall abuse' (17.8%). Compared with members of low abuse groups, youths who reported having experienced high/moderate levels of various forms of violence, including those who were abused in multiple ways and across the two settings ('high overall abuse'), were significantly more likely to engage in violent and hostile behavior. Abused and non-abused youths did not differ on non-violent conflict resolution skills. The significance of present findings for future research and practice is discussed.

2007-01-01

Although the use of multifamily group work is well established within the mental health field, it remains an underutilised method of treatment for families affected by brain injury. This paper reports on a pilot project exploring multifamily group work with families with a parent with an acquired brain injury. Six families met for a total of 12 sessions over a period of 6 months, with session themes informed by the Bouverie Family tasks model of adaptation post-ABI. The project was evaluated using qualitative and quantitative research methods, with pre, post group and 3 month follow up measures of individual, couple and family functioning. Parents reported generally reduced levels of personal distress at follow up but continuing high levels of marital and family dysfunction. Children were generally reported to be well functioning, although parents were particularly concerned about the impact of family disruption and violence on their children. Families were unequivocally positive about their participation in the group with benefits including reduced feelings of shame and isolation, provision of mutual support, increased understanding of brain injury, sharing of difficult experiences and movement from blame to compassion. Further research is warranted on the specific applications of multifamily group work with acquired brain injury.
Sexual abuse prevention with high-risk males: the roles of victim empathy and rape myths.

PubMed

Schewe, P A; O'Donohue, W

1993-01-01

The outcome of two sexual abuse prevention programs, one emphasizing victim empathy and the other stressing modifying rape myths, was evaluated with high-risk males. Sixty-eight high-risk males, as determined by self-reported likelihood of committing sexual abuse, were randomly assigned to an empathy-treatment, a facts-treatment, or a no-treatment control group. Treatment effects were assessed using subjects' pre- and post-treatment scores on the Likelihood of Sexually Abusing scale, the Rape Empathy Scale, the Acceptance of Interpersonal Violence scale, the Adversarial Sexual Beliefs Scale, and a test of self-reported sexual arousal to forced versus consenting sex. In addition, posttest scores on an Asch-type conformity measure were obtained. Results of validity checks indicated that high-risk subjects differed from low-risk subjects on a number of rape-related variables, that the victim-empathy condition increased subjects' empathy, and that subjects found both treatments to be credible and helpful. Comparisons between the empathy-, facts-, and no-treatment group contraindicated the practice of dispelling rape myths as a method of preventing rape among high-risk males.

2017-01-01

Individuals high in rejection sensitivity (RS) are at risk for experiencing high levels of interpersonal distress, yet little is known about the interpersonal profiles associated with RS. This investigation examined the interpersonal problems, sensitivities, and values associated with RS in 2 samples: 763 multicultural undergraduate students (Study 1) and 365 community adults (Study 2). In Study 1, high anxious RS was associated with socially avoidant interpersonal problems, whereas low anxious RS was associated with vindictive interpersonal problems. In Study 2, we assessed both anxious and angry expectations of rejection. Circumplex profile analyses showed that the high anxious RS group reported socially avoidant interpersonal problems, sensitivities to remoteness in others, and valuing connections with others, whereas the high angry RS group reported vindictive interpersonal problems, sensitivities to submissiveness in others, and valuing detached interpersonal behavior. Low anxious RS was related to domineering interpersonal problems, sensitivity to attention-seeking behavior, and valuing detached interpersonal behavior, whereas low angry RS was related to submissive interpersonal problems, sensitivity to attention-seeking behavior, and valuing receiving approval from others. Overall, results suggest that there are distinct interpersonal profiles associated with varying levels and types of RS.
Multimethod Investigation of Interpersonal Functioning in Borderline Personality Disorder

2011-01-01

Even though interpersonal functioning is of great clinical importance for patients with borderline personality disorder (BPD), the comparative validity of different assessment methods for interpersonal dysfunction has not yet been tested. This study examined multiple methods of assessing interpersonal functioning, including self- and other-reports, clinical ratings, electronic diaries, and social cognitions in three groups of psychiatric patients (N=138): patients with (1) BPD, (2) another personality disorder, and (3) Axis I psychopathology only. Using dominance analysis, we examined the predictive validity of each method in detecting changes in symptom distress and social functioning six months later. Across multiple methods, the BPD group often reported higher interpersonal dysfunction scores compared to other groups. Predictive validity results demonstrated that self-report and electronic diary ratings were the most important predictors of distress and social functioning. Our findings suggest that self-report scores and electronic diary ratings have high clinical utility, as these methods appear most sensitive to change. PMID:21808661
Do complaints of everyday cognitive failures in high schizotypy relate to emotional working memory deficits in the lab?

Carrigan, Nicole; Barkus, Emma; Ong, Adriel; Wei, Maryann

2017-10-01

Individuals high on schizotypy complain of increased cognitive failures in everyday life. However, the neuropsychological performance of this group does not consistently indicate underlying ability deficits. It is possible that current neuropsychological tests lack ecological validity. Given the increased affective reactivity of high schizotypes, they may be more sensitive to emotional content interfering with cognitive ability. This study sought to explore whether an affective n-back working memory task would elicit impaired performance in schizotypy, echoing complaints concerning real world cognition. 127 healthy participants completed self-report measures of schizotypy and cognitive failures and an affective n-back working memory task. This task was varied across three levels of load (1- to 3-back) and four types of stimulus emotion (neutral, fearful, happy, sad). Differences between high (n=39) and low (n=48) schizotypy groups on performance outcomes of hits and false alarms were examined, with emotion and load as within-groups variables. As expected, high schizotypes reported heightened vulnerability to cognitive failures. They also demonstrated a relative working memory impairment for emotional versus neutral stimuli, whereas low schizotypes did not. High schizotypes performed most poorly in response to fearful stimuli. For false alarms, there was an interaction between schizotypy, load, and emotion, such that high schizotypy was associated with deficits in response to fearful stimuli only at higher levels of task difficulty. Inclusion of self-reported cognitive failures did not account for this. These findings suggest that the "gap" between subjective and objective cognition in schizotypy may reflect the heightened emotional demands associated with cognitive functioning in the real world, although other factors also seem to play a role. There is a need to improve the ecological validity of objective assessments, whilst also recognizing that self-reported cognitive failures tap into a range of factors difficult to assess in the lab, including emotion. Cognitive interventions for at-risk individuals will likely be more beneficial if they address emotional processing alongside other aspects of cognition. Copyright © 2017 Elsevier Inc.

To evaluate a programme introducing quality improvement (QI) in nursing education. Betanien College of Nursing and clinical practices at hospitals in Bergen. 52 nursing students from a second year class working in 16 groups undertaking hospital based practical studies. Second year nursing students were assigned to follow a patient during a day's work and to record the processes of care from the patient's perspective. Data collected included waiting times, patient information, people in contact with the patient, investigations, and procedures performed. Students also identified aspects of practice that could be improved. They then attended a 2 day theoretical introductory course in QI and each group produced flow charts, cause/effect diagrams, and outlines of quality goals using structure, process, and results criteria to describe potential improvements. Each group produced a report of their findings. Main measures-A two-part questionnaire completed by the students before and after the intervention was used to assess the development of their understanding of QI. Evidence that students could apply a range of QI tools and techniques in the specific setting of a hospital ward was assessed from the final reports of their clinical attachments. The students had a significantly better knowledge of QI after the introductory course and group work than before it, and most students indicated that they considered the topic highly relevant for their later career. They reported that it was quite useful to observe one patient throughout one shift and, to some extent, they learned something new. Students found the introductory course and working in groups useful, and most thought the programme should be included in the curriculum for other nursing students. They considered it important for nurses in general to have knowledge about QI, indicating a high perceived relevance of the course. All 16 groups delivered reports of their group work which were approved by the tutors. Through the reports, all the groups demonstrated knowledge and ability to apply tools and techniques in their practical studies in a hospital setting. The introduction of a short experience-based programme into the practical studies of second year nursing students enabled them to learn about the concepts, tools, and techniques of continuous QI in a way that should provide them with the skills to undertake it as part of routine practice.

Female peers in small work groups enhance women's motivation, verbal participation, and career aspirations in engineering

Dasgupta, Nilanjana; Scircle, Melissa McManus; Hunsinger, Matthew

2015-01-01

For years, public discourse in science education, technology, and policy-making has focused on the “leaky pipeline” problem: the observation that fewer women than men enter science, technology, engineering, and mathematics fields and more women than men leave. Less attention has focused on experimentally testing solutions to this problem. We report an experiment investigating one solution: we created “microenvironments” (small groups) in engineering with varying proportions of women to identify which environment increases motivation and participation, and whether outcomes depend on students’ academic stage. Female engineering students were randomly assigned to one of three engineering groups of varying sex composition: 75% women, 50% women, or 25% women. For first-years, group composition had a large effect: women in female-majority and sex-parity groups felt less anxious than women in female-minority groups. However, among advanced students, sex composition had no effect on anxiety. Importantly, group composition significantly affected verbal participation, regardless of women’s academic seniority: women participated more in female-majority groups than sex-parity or female-minority groups. Additionally, when assigned to female-minority groups, women who harbored implicit masculine stereotypes about engineering reported less confidence and engineering career aspirations. However, in sex-parity and female-majority groups, confidence and career aspirations remained high regardless of implicit stereotypes. These data suggest that creating small groups with high proportions of women in otherwise male-dominated fields is one way to keep women engaged and aspiring toward engineering careers. Although sex parity works sometimes, it is insufficient to boost women’s verbal participation in group work, which often affects learning and mastery. PMID:25848061

Dandelion (Taraxacum officinale), an oriental herbal medicine, has been shown to favorably affect choleretic, antirheumatic and diuretin properties. Recent reports have indicated that excessive oxidative stress contributes to the development of atherosclerosis-linked metabolic syndrome. The objective of this current study was to investigate the possible hypolipidemic and antioxidative effects of dandelion root and leaf in rabbits fed with a high-cholesterol diet. A group of twenty eight male rabbits was divided into four subgroups; a normal diet group, a high-cholesterol diet group, a high-cholesterol diet with 1% (w/w) dandelion leaf group, and a high-cholesterol diet with 1% (w/w) dandelion root group. After the treatment period, the plasma antioxidant enzymes and lipid profiles were determined. Our results show that treatment with dandelion root and leaf positively changed plasma antioxidant enzyme activities and lipid profiles in cholesterol-fed rabbits, and thus may have potential hypolipidemic and antioxidant effects. Dandelion root and leaf could protect against oxidative stress linked atherosclerosis and decrease the atherogenic index. PMID:20162002

Uric acid has been proposed as an independent risk factor of diabetic retinopathy. Although Notch signaling was reported to be affected in the presence of high concentrations of uric acid or glucose, the underlying mechanisms of hyperuricemia through the Notch signaling pathway to promote the development of diabetic retinopathy remain unknown. We incubated human retinal endothelial cells (HRECs) with high glucose, high uric acid and high glucose plus high glucose respectively and evaluated the apoptosis rate in different treated cells by Tunel staining. We induced diabetic model by intraperitoneally streptozotocin. Then healthy rats and diabetic rats were given with adenine and oteracil potassium by gavage. Using automatic biochemical analyzer to detect blood glucose, uric acid, urea nitrogen, creatinine levels, to verify the success of modeling. The expression and mRNA levels of ICAM-1, IL-6, MCP-1, TNF-a, receptors Notch 1, ligands Dll 1, Dll 4, Jagged 1, Jagged 2 were detected by RT-PCR and Western-Blot. Notch1 siRNA was used to interfere Notch signaling pathway, the expression and mRNA levels of ICAM-1, IL-6, MCP-1 and TNF-α was detected by RT-PCR and Western blot respectively. In vitro models, the apoptosis of HRECs cells in high uric acid plus high glucose group was the most significant. In vitro and vivo models, detection of inflammatory cytokines revealed that the expression of inflammatory cytokines increased most significantly in high uric acid plus high glucose group. Notch signaling pathway activity was also increased most significantly in high uric acid plus high glucose group. After Notch 1 siRNA transfection in high glucose and high glucose plus uric acid group, the activity of Notch signaling pathway was successfully down-regulated. We found that the apoptosis of HRECs was significantly decreased in cells transfected with Notch 1 siRNA compared to the blank vector group, and the expression of inflammatory cytokines in cells was also significantly decreased. Our study reported that high uric acid can promote the inflammation of the retina and increase the activity of Notch signaling pathway on the basis of high glucose. Hyperuricemia promotes the development of diabetic retinopathy by increasing the activity of Notch signaling pathway. Notch signaling pathway is a potential therapeutic target for diabetic retinopathy. Copyright © 2018. Published by Elsevier Inc.
What about N? A methodological study of sample-size reporting in focus group studies.

Focus group studies are increasingly published in health related journals, but we know little about how researchers use this method, particularly how they determine the number of focus groups to conduct. The methodological literature commonly advises researchers to follow principles of data saturation, although practical advise on how to do this is lacking. Our objectives were firstly, to describe the current status of sample size in focus group studies reported in health journals. Secondly, to assess whether and how researchers explain the number of focus groups they carry out. We searched PubMed for studies that had used focus groups and that had been published in open access journals during 2008, and extracted data on the number of focus groups and on any explanation authors gave for this number. We also did a qualitative assessment of the papers with regard to how number of groups was explained and discussed. We identified 220 papers published in 117 journals. In these papers insufficient reporting of sample sizes was common. The number of focus groups conducted varied greatly (mean 8.4, median 5, range 1 to 96). Thirty seven (17%) studies attempted to explain the number of groups. Six studies referred to rules of thumb in the literature, three stated that they were unable to organize more groups for practical reasons, while 28 studies stated that they had reached a point of saturation. Among those stating that they had reached a point of saturation, several appeared not to have followed principles from grounded theory where data collection and analysis is an iterative process until saturation is reached. Studies with high numbers of focus groups did not offer explanations for number of groups. Too much data as a study weakness was not an issue discussed in any of the reviewed papers. Based on these findings we suggest that journals adopt more stringent requirements for focus group method reporting. The often poor and inconsistent reporting seen in these studies may also reflect the lack of clear, evidence-based guidance about deciding on sample size. More empirical research is needed to develop focus group methodology.

Objective To investigate in a secondary analysis of a randomised trial the effects of a low-/high-fat diet and reported change from baseline in energy% from protein (prot%), in relation to changes in body size and metabolic factors. Methods Obese adults (n = 771) were randomised to a 600 kcal energy-deficient low-fat (20-25 fat%) or high-fat (40-45 fat%) diet over 10 weeks. Dietary intake data at baseline and during the intervention were available in 585 completers. We used linear regression to calculate the combined effects of randomised group and groups of prot% change (<−2 /−2 to 2/>2) on outcomes. Results The low-fat group with >2 prot% increase lost 1.1 kg more weight (p = 0.03) and reduced cholesterol by 0.25 mmol/l more (p = 0.003) than the high-fat group with >2 prot% decrease. These differences were 2.5-fold and 1.8-fold greater than the differences between the low-fat and high-fat groups while not considering prot% change. The high-fat group reduced plasma triglycerides more than the low-fat group, but not compared to those in the low-fat group with >2 units prot% increase (p fat-protein interaction = 0.01). Conclusions Under energy restriction, participants on a low-fat diet who had increased the percentage energy intake from protein showed the greatest reduction in weight and cholesterol, and a triglyceride reduction equally large to that of participants on a high-fat diet.

The state of the art for treatment efficacy studies now requires manual guided treatments and tests of therapist adherence. This report provides findings regarding adherence assessment of therapists participating in an investigation of treatment matching in adolescent substance abusers. The Group Sessions Rating Scale (GSRS), a group-therapy process measure, was studied to determine its appropriateness for assessing group treatment of adolescents with a) substance use disorders (SUD), b) interrater reliability, c) internal consistency, and d) ability to discriminate the active ingredients of cognitive-behavioral therapy (CBT) from interactional therapy (IT). Interrater reliabilities were moderate to high, with those for CBT generally higher than those for IT. Internal consistency of CBT items was moderate, whereas those of IT were moderately high. Discriminability between the two treatment modalities was high. The frequency of active ingredients was generally therapy-specific: high for the relevant and low for the nonrelevant therapeutic modality items. The GSRS was found to be effective in the measurement of treatment process in adolescents with SUD.

2009-01-01

This study examined the developmental trajectory of anxiety symptoms among 290 boys and evaluated the association of trajectory groups with child and family risk factors and children’s internalizing disorders. Anxiety symptoms were measured using maternal reports from the Child Behavior Checklist (T. M. Achenbach, 1991, 1992) for boys between the ages of 2 and 10. A group-based trajectory analysis revealed 4 distinct trajectories in the development of anxiety symptoms: low, low increasing, high declining, and high-increasing trajectories. Child shy temperament tended to differentiate between initial high and low groups, whereas maternal negative control and maternal depression were associated with increasing trajectories and elevated anxiety symptoms in middle childhood. Follow-up analyses to diagnoses of preadolescent depression and/or anxiety disorders revealed different patterns on the basis of trajectory group membership. The results are discussed in terms of the mechanisms of risk factors and implications for early identification and prevention. PMID:18266484

Congenital heart disease (CHD) is the most common birth defect, affecting about 0.8% of live births. Advances in recent decades have allowed >85% of children with CHD to survive to adulthood, creating a growing population of adults with CHD. Little information exists regarding survival, demographics, late outcomes, and comorbidities in this emerging group, and multiple barriers impede research in adult CHD (ACHD). The National Heart, Lung, and Blood Institute and the Adult Congenital Heart Association convened a multidisciplinary Working Group to identify high-impact research questions in ACHD. This report summarizes the meeting discussions in the broad areas of CHD-related heart failure, vascular disease and multisystem complications. High-priority subtopics identified included heart failure in tetralogy of Fallot, mechanical circulatory support/transplantation, sudden cardiac death, vascular outcomes in coarctation of the aorta, late outcomes in single ventricle disease, cognitive and psychiatric issues, and pregnancy.

The effect of induced self-presentation concerns on cognitive appraisal and affect.

PubMed

Howle, Timothy C; Eklund, Robert C

2013-01-01

An experiment was conducted to investigate how self-presentation imperatives can influence cognition and affect. Participants were 70 collegiate and recreational athletes who were recruited because of the relevance of self-presentation processes in sport. Athletes were asked to read either a script which de-emphasized self-presentation concerns (low self-presentation) or emphasized self-presentation concerns (high self-presentation). The scripts were developed for the purpose of the study and depicted a pre-competition scenario. The low self-presentation manipulation group reported more of a challenge state of appraisal, higher self-efficacy, lower avoidance goal focus, and more positive affect, while the high self-presentation manipulation group reported more of a threat state of cognitive appraisal and more negative affect. Nonsignificant differences were observed between groups for the perception of positive affect and negative affect. These findings provide preliminary evidence that self-presentation imperatives can impact the cognitive appraisal and affect of athletes as they prepare for competition.

Men who purchase sex (MWPS) have long been considered as one of the population groups at risk of HIV transmission. However, while HIV-related interventions have been targeted towards this group, few studies have directly recruited MWPS to measure the impact of such interventions. This study aimed to fill the gap for Indonesia by identifying the level and predictors of condom use and HIV testing among MWPS, to inform prevention strategies. A cross-sectional study was conducted by surveying 200 MWPS in Bali, Indonesia in 2015. A structured questionnaire was administered to collect the data. Self-reported condom use on the occasion of last paid sex was very high (88.5%), while a history of HIV testing was low (8.1%). None of the variables identified in this study were associated with condom use at last paid sex. Men were more likely to report a history of HIV testing if they: perceived themselves to be at high risk of HIV, had a higher level of HIV-related knowledge, reported a history of genital ulcers or urethral discharge in the past 12 months, or were aware that confidential HIV testing was available. Implications and limitations of this study are discussed.

Background Cigarette smoking is a chronic, relapsing illness that is inadequately addressed in primary care practice. Objective To compare cessation rates among smokers receiving pharmacotherapy management alone or combined with either moderate- or high-intensity disease management that includes counseling and provider feedback. Design Randomized clinical trial from June 2004 to December 2007. Setting 50 rural primary care practices. Patients 750 patients smoking ≥ 10 cigarettes/day. Intervention Participants were randomized to one of three groups: pharmacotherapy management (n = 250); pharmacotherapy management supplemented with up to 2 counseling calls (moderate-intensity disease management (n = 249)); or pharmacotherapy management supplemented with up to 6 counseling calls (high-intensity disease management (n = 251)). Interventions were offered every six months for two years. All participants received offers of free pharmacotherapy; moderate-intensity and high-intensity disease management recipients had post-counseling progress reports faxed to their physicians. Participants and counselors were not blinded to treatment assignment. Measurements Self-reported point-prevalence smoking abstinence at 24 months (primary outcome) and overall (0 to 24 months) analyses of smoking abstinence, utilization of pharmacotherapy, and discussions about smoking with physicians (secondary outcomes). Research assistants, blinded to treatment assignment, conducted outcome assessments. Results Pharmacotherapy utilization was comparable across treatment groups, with 473 of 741 (63.8%), 302 of 739 (40.9%), 175 of 732 (23.9%), and 179 of 726 (24.7%) requesting pharmacotherapy during the 1st, 2nd, 3rd, and 4th 6-month cycles of treatment. Of participants that saw a physician during any given treatment cycle, 37.5 – 59.5% reported that they discussed smoking cessation with their physician, but this did not differ across the treatment groups. Abstinence rates increased throughout the 24-month study and overall (0 to 24 months) analyses demonstrated higher abstinence among recipients of high-intensity versus moderate-intensity disease management (OR, 1.43 [95% CI, 1.00 to 2.03]) and higher abstinence in the combined disease management groups compared to pharmacotherapy management alone (OR, 1.47 [95% CI, 1.08 to 2.00]). The primary outcome, self-reported abstinence at 24 months, was 68 of 244 (27.9%) and 56 of 238 (23.5%) in the high-intensity and moderate-intensity disease management groups, respectively (OR, 1.33 [95% CI, 0.88 to 2.02]) and 56 of 244 (23.0%) in the pharmacotherapy management group (OR, 1.12 [95% CI, 0.78 to 1.61] (combined disease management versus pharmacotherapy management alone)). Limitations The impact of pharmacotherapy management cannot be separated from the provision of free pharmacotherapy. Cessation was validated in only 58% of self-reported quitters. Conclusion Smokers are willing to make repeated pharmacotherapy-assisted quit attempts leading to progressively greater smoking abstinence. Although point-prevalence abstinence was not different at 24 months, analyses that incorporated assessments across the full 24 months of treatment suggest that higher intensity disease management is associated with increased abstinence.

2014-11-01

This study examined separate developmental trajectories of anxious and depressive symptoms from childhood to adolescence (9-15 years) in a community-based sample (N = 290). At three measurement points, mothers and fathers reported on their children's anxious and depressive symptoms, and at Time 1 they reported on lower order child personality facets and on their parenting. By means of growth mixture modeling, three developmental trajectories were identified for anxious symptoms: steady low (82%), moderate increasing-decreasing (5.9%), and high declining groups (12.1%). For depressive symptoms, two developmental trajectories were found: steady low (94.1%) and moderate increasing groups (5.9%). Higher shyness, irritability, and altruism predicted membership in more problematic anxious and depressive groups. The personality facets energy, optimism, compliance, and anxiety were unique predictors for class membership for anxious symptoms, and the effects of shyness, irritability, and compliance were moderated by overreactive parenting. Shyness and irritability increased the probability of following the moderate increasing-decreasing anxiety trajectory, but only in the context of high or average levels of overreactive parenting. Compliance increased the probability of following the moderate increasing-decreasing and high decreasing trajectories in the context of high overreactive parenting. Our results indicate that childhood personality facets differentiate trajectories of anxious and depressive symptoms in theoretically compelling ways.
Psychological trauma exposure and trauma symptoms among individuals with high and low levels of dental anxiety.

2006-08-01

This questionnaire-based study investigated the traumatic background and trauma-related symptomatology among 141 treatment-seeking individuals with high levels of dental anxiety and among a low-anxious reference group consisting of 99 regular dental patients. The highly anxious individuals reported a significantly higher number of traumatic events, both within and outside the dental or medical setting, than those in the reference group (73% vs. 21%). Horrific experiences in the dental setting were the most common traumatic events reported. Of the highly anxious individuals, 46.1% indicated suffering from one or more of the post-traumatic stress disorder (PTSD) symptom clusters (re-experiencing, avoidance, loss of interest, and insomnia), while in the reference group this percentage was 6%. Severity of dental anxiety was significantly associated with number of screening criteria for specific phobia and the extent to which the anxious subjects displayed symptoms of post-traumatic stress. Two variables were uniquely predictive for positive diagnostic screens for dental phobia and PTSD: having experienced a horrific dental treatment and having been a victim of a violent crime. In conclusion, post-traumatic symptoms are common accompaniments of severe forms of dental anxiety and are experienced even when dental treatment is not imminent.

White-eyelid mangabeys (genus Cercocebus) live in groups of highly variable size. Because of their semi-terrestrial behaviour and preference for dense forest habitats, re-liable data on group size are scarce. During a 5-month study, we collected 17 group counts on a habituated group of agile mangabeys (C. agilis) at Bai Hokou in the Central African Republic. We found a stable group size of approximately 135 individuals. This permanent large grouping pattern is known to occur among several populations of white-eyelid mangabeys and is congruent with extreme group sizes reported in mandrills at Lopé in Gabon.

2016-04-01

Menu energy labelling at point of purchase is gaining traction worldwide, yet the potential impact for different socioeconomic groups is unclear. We aimed to summarise evidence on the effectiveness of menu energy labelling by socioeconomic position (SEP). A systematic search for papers published to September 2015 was conducted using terms for labelling, food outlets, and SEP. Quality of studies was assessed. Results were summarised across stages of an intervention logic pathway. Eighteen papers were identified. Of twelve studies reporting the effect of menu energy labelling in low SEP populations, six reported on purchase outcomes. All but one of these reported no positive effect of the policy for this population. Two of the five studies that compared purchase outcomes of menu labelling across SEP groups reported that the policy was effective overall. These two studies reported either a significant decline in fast food calories purchased from consumers in high (but not low) SEP neighbourhoods or a significantly greater decline in calories purchased among consumers visiting stores in higher SEP neighbourhoods post policy implementation. None of the included papers reached the highest quality score. The current evidence describing the impact of menu energy labelling within or across SEP is limited in quantity and quality. Of the two studies that reported a positive benefit of menu energy labelling overall, both identified a greater effect on fast food purchases among consumers visiting stores in high compared to low SEP neighbourhoods. It is difficult to know whether the absence of effectiveness reported in low SEP populations represents a true lack of effectiveness or is a result of a more general lack of policy effectiveness or the limited quality of the reviewed studies.

On the association between sexual attraction and adolescent risk behavior involvement: Examining mediation and moderation.

Busseri, Michael A; Willoughby, Teena; Chalmers, Heather; Bogaert, Anthony F

2008-01-01

On the basis of a large-scale survey of high-school youth, the authors compared adolescents reporting exclusively heterosexual, mostly heterosexual, bisexual, and predominately same-sex attraction based on high-risk involvement across a range of risk behaviors. Bisexual and same-sex attracted groups were characterized by heightened high-risk involvement relative to the other two groups. Mediation analysis was used to determine whether these group disparities were explained by a set of normative predictive factors spanning multiple life domains. Differences among a combined exclusively/mostly heterosexual attraction group and both the bisexual and same-sex attraction groups were attenuated (66% and 50%, respectively) after incorporating the hypothesized intervening predictive factors, providing evidence of partial mediation. Primary mediators included intrapersonal (attitudes toward risk-taking; academic orientation), interpersonal (peer victimization; parental relationships; unstructured activities), and environmental (substance availability) factors. Mediation results were consistent across participant age and sex. Implications, limitations, and directions for future research are discussed. Copyright (c) 2008 APA.

Risk of cardiovascular disease varies between ethnic groups and the aim of this study was to investigate differences in cardiovascular risk factors, and total cardiovascular risk between ethnic groups in Norway. Cross-sectional study using data from the Cohort of Norway (CONOR). A sample of 62,145 participants, 40-65 years of age, originating from 11 geographical regions, were included in our study. Self-reported variables, blood samples and physical measurements were used to estimate age- and time-adjusted mean values of cardiovascular risk factors for different ethnic groups. The 10-year risks of cardiovascular mortality and cardiovascular events were calculated using the Framingham and NORRISK risk models. We observed differences between ethnic groups for cardiovascular risk factors and both Framingham and NORRISK risk scores. NORRISK showed significant differences by ethnicity in women only. Immigrants from the Indian subcontinent had the lowest high-density lipoprotein (HDL) levels, the highest levels of blood glucose, triglycerides, total cholesterol/HDL ratio, waist hip ratio and diabetes prevalence. Immigrants from the former Yugoslavia had the highest Framingham scores, high blood pressure, high total cholesterol/HDL ratio, overweight measures and smoking. Low cardiovascular risk was observed among East Asian immigrants. The previously reported excess cardiovascular risk among immigrants from the Indian subcontinent was supported in this study. We also showed that immigrants from the former Yugoslavian countries had a higher total 10-year risk of cardiovascular events than other ethnic groups. This study adds information about ethnic groups in Norway which needs to be addressed in further research and targeted prevention strategies.

Several investigators have reported the effects of reduced training and interrupted training on athletic performance, but few reports are available for soccer players. The purpose of this study was to examine, using the Yo-Yo intermittent recovery level 2 (YoYoIR2) test and sprint performance, the effects on soccer players of a reduced training program consisting of either moderate running training, plyometric training. After the completion of a competitive season, 29 male soccer players were divided into 3 groups: the running group (n = 13), the plyometric group (n = 11), and the control group (n = 5). Both training groups completed either running or plyometric training sessions 2 d·wk(-1) for 3 weeks, whereas the control group was not allowed to perform any training. The subjects performed YoYoIR2 and 20-m sprint tests before (pre) and after (post) the experimental period. Neither training group showed any significant training effects on the YoYoIR2 performance or 20-m sprint times compared with the control group. This study suggests that neither endurance running nor plyometric training 2 d·wk(-1) for 3 weeks has a significant effect on high-intensity performance compared with a nontraining regimen. However, our results do not support complete inactivity. These results may have important implications for the management of training cessation for a few weeks.

To investigate whether Australian Gulf War veterans have a higher than expected prevalence of recent symptoms and medical conditions that were first diagnosed in the period following the 1991 Gulf War; and if so, whether these effects were associated with exposures and experiences that occurred in the Gulf War. Cross-sectional study of 1456 Australian Gulf War veterans and a comparison group who were in operational units at the time of the Gulf War, but were not deployed to that conflict (n = 1588). A postal questionnaire was administered and the likelihood of the diagnosis of self-reported medical conditions was assessed and rated by a medical practitioner. Gulf War veterans had a higher prevalence of all self-reported health symptoms than the comparison group, and more of the Gulf War veterans had severe symptoms. Increased symptom reporting was associated with several exposures, including having more than 10 immunisations, pyridostigmine bromide tablets, anti-biological warfare tablets, pesticides, insect repellents, reportedly being in a chemical weapons area, and stressful military service experiences in a strong dose-response relation. Gulf War veterans reported psychological (particularly post-traumatic stress disorder), skin, eye, and sinus conditions first diagnosed in 1991 or later more commonly than the comparison group. Over 90% of medical conditions reported by both study groups were rated by a medical practitioner as having a high likelihood of diagnosis. More than 10 years after the 1991 Gulf War, Australian veterans self-report all symptoms and some medical conditions more commonly than the comparison group. Further analysis of the severity of symptoms and likelihood of the diagnosis of medical conditions suggested that these findings are not due to over-reporting or to participation bias.

Despite the high prevalence of genital pain in healthy young adult women, limited research has addressed genital pain during intercourse using contemporary models of multidimensional sexual function. The objectives of this study were threefold: (1) to identify differences in sexual functioning in women who experience genital pain compared to pain free women; (2) to identify predictors of sexual functioning in women with and without genital pain; and (3) to identify predictors of sexual satisfaction in women with and without genital pain. Sexually active female undergraduates (n = 651) were administered the Female Sexual Function Index and the Derogatis Sexual Functioning Inventory. We evaluated the sexual factors that impact the sexual function of women with any pain (including high and low pain groups) versus women with no history of pain. Women with genital pain reported greater rates of sexual dysfunction as compared to pain-free women; however, sexual functioning in the high versus low pain groups was distinguished primarily by vaginal lubrication. Women in the high pain group showed negative correlations between domains of sexual satisfaction and genital pain frequency and intensity that were not found in the low pain group. For pain-free women, intercourse played a strong role in sexual satisfaction, whereas non-intercourse sexual behavior was central to sexual satisfaction in women who reported pain. The evaluation of levels of genital pain may provide insight into the mechanisms underlying the impairment of sexual function, sexual behavior, and sexual satisfaction. PMID:17674182

Autism is generally associated with poor functional outcome but little is known about predictors of quality of life, especially during early adulthood. This study was conducted to assess subjective quality of life during early adulthood in high-functioning autism spectrum disorder and its relation with self-regulating abilities. Individuals with high-functioning autism spectrum disorder who progressed into post-secondary higher education ( N = 75) were compared to a typical peer control group ( N = 28) based on behavioral self-report questionnaires. The results indicated that individuals with high-functioning autism spectrum disorder reported significantly lower subjective quality of life than typical controls ( p < 0.001, effect size ( d) = 1.84). In addition, individuals with high-functioning autism spectrum disorder reported more problems with emotion processing ( p < 0.05, effect size ( d) = 0.79) and daily executive functioning ( p < 0.001, effect size ( d) = 1.29) than controls. A higher level of executive functioning problems was related to lower quality of life in the high-functioning autism spectrum disorder group, but no significant relation between level of emotion processing and subjective quality of life became apparent in the regression analysis. Our findings show that even in high-functioning young adults with autism, executive functioning, emotion processing, and subjective quality of life are low compared to typically developing peers. Furthermore, these results emphasize the importance of targeting executive functioning problems in individuals with autism to improve subjective quality of life.

This study examines the association between family function and self-esteem of Chinese university students with grandparenting experience, and explores the moderating effects of social support in this link. Two thousand five hundred thirty university students (1372 males and 1158 females) from a Chinese university completed the Perceived Social Support Scale, the Rosenberg’s Self-esteem Scale, and the Family Assessment Device (FAD). Six hundred and forty-five (25.69%) students reported grandparenting experience and they reported lower scores on self-esteem and social support than the students raised only by their parents. The grandparenting group scored higher on such dimensions of family functioning as Communication, Role, Affective Involvement, Affective Responsiveness, and General Family Function (GF) than their counterpart group. For both groups, self-esteem scores were positively correlated with social support scores, while negatively correlated with FAD all sub-scale scores. Hierarchical regression analysis showed that for the students with grandparenting experience the social support moderated the relationship between GF and self-esteem. When students reported a high level of social support, those with low GF score reported higher scores in self-esteem than those with low self-esteem. However, in case of low social support, there were no differences in self-esteem between groups with high and low GF scores. These findings suggest that social support plays a positive role to relieve the adverse impact of poor family function on self-esteem of the adolescents with grandparenting experience. In addition, the significance and limitations of the results will be discussed. PMID:28611720

Mood disorders are prevalent in people after stroke, and a disorder's onset can exacerbate stroke-related disabilities. While evidence supports the mental-health benefits of participation in exercise and yoga, it is unknown whether such benefits extend to a population with poststroke hemiparesis. The study investigated whether supplementing exercise with participation in a yoga program would provide further improvements in self-reported symptoms of depression and anxiety in a chronic poststroke population, and it also assessed trial feasibility for future studies. The research team designed a randomized, controlled pilot trial that included an exercise-only group (EX, control) and a yoga-and-exercise group (YEX, intervention). The study took place at the Centre for Physical Activity in Ageing an exercise rehabilitation and activity center at the Royal Adelaide Hospital in South Australia. The participants included 14 individuals with chronic poststroke hemiparesis: eight in the intervention group and six in the control group. The YEX group participated in a 6-week standardized program that included yoga in weekly group sessions and home practice in addition to exercise in a weekly group class. The EX group participated only in the group exercise class weekly for 6 weeks. The research team assessed self-reported symptoms of depression using the Geriatric Depression Scale (GDS15) and symptoms of anxiety and negative affect using the State Trait Anxiety Inventory (STAI). The team based the feasibility evaluation on recruitment outcomes, retention of participants, participants' compliance with the intervention program, and the safety of the intervention. Changes in depression and state and trait anxiety did not significantly differ between intervention groups (GDS15 P=.749, STAI-Y1, P=.595, STAI-Y2, P=.407). Comparison of individuals' case results indicated clinically relevant improvements in both groups, although members of the intervention group had greater improvements. Participants reported no adverse events, and the study experienced high retention of participants and high compliance in the yoga program. This pilot study provides preliminary data on the effects of yoga combined with exercise to influence mood poststroke. It is a feasible, safe, and acceptable intervention, and the field requires additional investigations with a larger sample size.
Perspective Taking Explains Gender Differences in Late Adolescents' Attitudes Toward Disadvantaged Groups.

Adolescents' attitudes toward disadvantaged groups are surprisingly understudied. What we know from these few studies is that adolescents' attitudes tend to become more favorable over time and that adolescent girls display more favorable attitudes than do adolescent boys. However, researchers have not offered explanations for why these effects occur. We proposed that changes in social-cognitive abilities that accompany adolescent development increase perspective taking and that the increased perspective taking facilitates more favorable attitudes toward disadvantaged groups. Because girls develop social-cognitive abilities earlier than boys, girls should show greater perspective taking and thus more positive attitudes toward disadvantaged groups than should boys. Importantly, we propose that these more positive attitudes are explained better by perspective taking than by gender. Participants were late adolescents (n = 803, 53.3 % female, ages 15-19) from high schools in north-central Florida (United States) participating in an ongoing, multi-wave study. Participants completed a measure of perspective-taking and reported their attitudes toward three disadvantaged groups (Black, gay, and poor people) during their third year of high school and, again, 6 months later during their fourth year of high school. Our findings provided strong support for our theorizing. Girls generally reported warmer attitudes than did boys toward disadvantaged groups, with the gender differences in warmth tending to diminish across time. Similarly, girls were higher than boys in perspective-taking abilities at both time points, although boys increased over time whereas girls did not. Crucially, perspective taking mediated observed gender differences in attitudes, suggesting that perspective taking is a mechanism for improving attitudes toward disadvantaged groups during late adolescence.

The study objective was to evaluate the effect of prescribing a low-carbohydrate diet (LCD) and a low-fat diet (LFD) on food cravings, food preferences, and appetite. Obese adults were randomly assigned to a LCD (n=134) or a LFD (n=136) for two years. Cravings for specific types of foods (sweets, high-fats, fast-food fats, carbohydrates/starches); preferences for high-sugar, high-carbohydrate, and low-carbohydrate/high-protein foods; and appetite were measured during the trial and evaluated during this secondary analysis of trial data. Differences between the LCD and LFD on change in outcome variables were examined with mixed linear models. Compared to the LFD, the LCD had significantly larger decreases in cravings for carbohydrates/starches and preferences for high-carbohydrate and high-sugar foods. The LCD group reported being less bothered by hunger compared to the LFD group. Compared to the LCD group, the LFD group had significantly larger decreases in cravings for high-fat foods and preference for low-carbohydrate/high-protein foods. Men had larger decreases in appetite ratings compared to women. Prescription of diets that promoted restriction of specific types of foods resulted in decreased cravings and preferences for the foods that were targeted for restriction. The results also indicate that the LCD group was less bothered by hunger compared to the LFD group and that men had larger reductions in appetite compared to women. PMID:21494226

Selenium (Se) has been reported to protect against the neurotoxicity of mercury (Hg). However, the effect of Se against Hg on cardiovascular diseases remains unclear. Inuit living in the Arctic have high exposure to both Se and Hg through their marine mammal and fish rich traditional diet. To characterize the co-exposure of Hg and Se among Inuit in Canada and to assess the associations between Hg, Se and cardiovascular health outcomes, including stroke, hypertension, and myocardial infarction (MI). Data was collected from the International Polar Year Inuit Health Survey (IHS) conducted in 2007 and 2008. Blood Se and Hg were measured, and self-report cardiovascular health outcomes were collected through a questionnaire interview from 2169 adults aged 18 and above. The mean age was 42.4years, and 38.7% of the participants were male. The geometric means (GM) of blood Se and total Hg were 319.5μg/L and 7.0μg/L, respectively. The crude prevalence of heart attack, stroke and hypertension were 3.55%, 2.36%, and 24.47% respectively. Participants were categorized into 4 exposure groups according to blood Hg (high: ≥7.8μg/L; low: <7.8μg/L), and Se (high: ≥280μg/L; low: <280μg/L). The odds ratio (OR) of cardiovascular outcomes were estimated using general linearized models. Results showed the low Se and high Hg group had a higher prevalence of cardiovascular disease (OR=1.76 for hypertension, 1.57 for stroke, and 1.26 for MI. However, the prevalence was decreased in both the high Se and low Hg group (OR=0.57 for hypertension, 0.44 for stroke, and 0.27 for MI) and the high Se and high Hg group (OR=1.14 for hypertension, 0.31 for stroke, and 0.80 for MI). The high Se and low Hg group had the lowest prevalence of cardiovascular outcomes, except for stroke. These results provide evidence that Se may exhibit a protective effect against Hg on cardiovascular disease. Copyright © 2017 Elsevier Ltd. All rights reserved.

Korean Curcuma longa L. induces lipolysis and regulates leptin in adipocyte cells and rats

Song, Won-Yeong

2016-01-01

BACKGROUND/OBJECTIVES Turmeric (Curcuma longa L.) has been reported to have many biological functions including anti-obesity. Leptin, peptide hormone produced by adipocytes and its concentration is increased in proportion to the amount of the adipocytes. In the present study, we examined the effects of Korean turmeric on the regulation of adiposity and leptin levels in 3T3-L1 adipocytes and rats fed a high-fat and high-cholesterol diet. MATERIALS/METHODS Leptin secretion, free fatty acid and glycerol contents in 3T3-L1 adipocytes were measured after incubation of cells with turmeric for 24 hours. Rats were divided into four experimental groups: a normal diet group (N), a high-fat and high-cholesterol diet group (HF), a high-fat and high-cholesterol diet group supplemented with 2.5% turmeric extracts (TPA group) and a high-fat and high-cholesterol diet group supplemented with 5% turmeric extracts (TPB group). Serum samples were used for the measurement of leptin concentration. RESULTS Contents of free fatty acid and glycerol showed concentration dependent increase in response to turmeric extracts. Effects of turmeric extracts on reduction of lipid accumulation in 3T3-L1 cells were examined by Oil Red O staining. Treatment with turmeric extracts resulted in increased expression levels of adipose triglyceride lipase and hormone-sensitive lipase mRNA. The concentration of leptin from 3T3-L1 adipocytes was significantly decreased by turmeric. Proportional abdominal and epididymal fats weights of the turmeric 5% supplemented group, TPB has significantly decreased compared to the HF group. The serum levels of leptin in the TPA and TPB groups were significantly lower than those of the HF group. CONCLUSIONS Based on these results, we suggested that Korean turmeric may contribute to the decreasing of body fat and regulating leptin secretion. PMID:27698955

Objective Assessment of daily functions affected by cognitive loss in prodromal Huntington disease (HD) is necessary in practice and clinical trials. We evaluated baseline and longitudinal sensitivity of the Everyday Cognition (ECog) scales in prodromal HD and compared self- and companion-ratings. Method Everyday cognition was self-assessed by 850 participants with prodromal HD and 768 companions. We examined internal structure using confirmatory factor analysis (CFA) on baseline data. For longitudinal analysis, we stratified participants into Low, Medium, and High disease progression groups. We examined ECog scores for group differences and participant-and-companion differences using linear mixed effects regression (LMER). Comparison with the Total Functional Capacity (TFC) scale was made. Results CFA revealed good fit of a 5-factor model having a global factor (total score), and sub factors (subscales) of memory, language, visuospatial perception, and executive function. At study entry, participants and companions in the Medium and High groups reported significantly worsened everyday cognition as well as significant functional decline over time. Losses became more pronounced and participant and companion ratings diverged as individuals progressed. TFC showed significant functional loss over time in the High group but not in the Medium group. Conclusions Disease progression is associated with reduced self- and companion-reported everyday cognition in prodromal HD participants who are less than 13 years to estimated motor onset. Our findings suggest companion ratings are more sensitive than participants’ for detecting longitudinal change in daily cognitive function. ECog appears more sensitive to specific functional changes in the prodrome of HD than the TFC. PMID:25000321

There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions. Cross-sectional study; Level of evidence, 3. Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines). In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting. © 2016 The Author(s).

Clinical research professionals are faced with decreased funding and increased workloads; innovative methods of professional development programs are necessary to accommodate these factors. This study evaluated the feasibility, perceived satisfaction, and value of using webinars to educate clinical research professionals on reporting adverse events commonly experienced in pediatric oncology clinical trials. The setting incorporated synchronous web-based educational technology. Constructivist learning provides the theoretical framework for this study. Participants evaluated the professional development program at 2 time points: (a) at the conclusion and (b) 4 to 6 weeks afterward, using survey method. Synchronous webinars were both economical and effective in educating clinical research professionals across institutional sites. Participants reported exceptionally high levels of satisfaction with the accessibility, scope, quality, and interactivity of the professional development program. The vast majority of participants reported that the education would assist with reporting adverse events in pediatric oncology clinical trials and this perception persisted into clinical practice. Although the results of this study were intended to guide future educational efforts of the Children's Oncology Group, they may also apply to other cooperative groups.

The Tromsø Intervention Study on Preterms evaluates an early, sensitizing intervention given to parents of prematurely born children (birth-weight < 2000 g). The current study investigated the potential influence of the intervention on children's self-reported and parental proxy-reported quality of life (QoL) at children's age of nine. Participants were randomized to either intervention (PI, n = 72) or preterm control (PC, n = 74) in the neonatal care unit, while healthy term-born infants were recruited to a term reference group (TR, n = 75). The intervention was a modified version of the Mother-Infant Transaction Program, and comprised eight one-hour sessions during the last week before discharge and four home visits at 1, 2, 4 and 12 weeks post-discharge. The two control groups received care in accordance with written guidelines drawn up at the hospital. Participants and parents reported QoL independently on the Kinder Lebensqualität Fragebogen (KINDL) questionnaire. Differences between groups were analyzed by SPSS; Linear Mixed Models and parent-child agreement were analyzed and compared by intra-class correlations within each group. On average, children in all groups reported high levels of well-being. The PI children reported better physical well-being than the PC children (p = 0.002). In all other aspects of QoL both the PI and the PC children reported at similar levels as the term reference group. PI parents reported better emotional wellbeing (p = 0.05) and a higher level of contentment in school (p = 0.003) compared with PC parents. Parent-child agreement was significantly weaker in the PI group than in the PC group on dimensions such as emotional well-being and relationships with friends (p < 0.05). PI parents reported QoL similar to parents of terms on all aspects except the subscale self-esteem, while PC parents generally reported moderately lower QoL than TR parents. This early intervention appears to have generated long-lasting positive effects, improving perceived physical well-being among prematurely born children and parent's perception of these children's QoL in middle childhood.

Previous studies have shown reduced empathic responsiveness to others' emotions in preschoolers with autism spectrum disorder (ASD) and an intellectual disability. However, age and intelligence may promote children's empathic responsiveness. Therefore, we examined the empathic responsiveness in normally intelligent school-aged children and adolescents with a clinical diagnosis of ASD (n = 151) and in a typically developing comparison group (n = 50), using structured observations and parent reports. Based on the observations, participants' responses to the emotional displays of an interviewer were surprisingly similar. However, compared with parents from the comparison group, parents of a child with ASD reported significantly fewer empathic responses, particularly when the child received a high score on the Autism Diagnostic Observation Schedule. Even though parents report a reduced empathic responsiveness in school-aged children and adolescents with ASD, it may be difficult to find these empathic limitations during brief observations in a structured setting. © 2013 International Society for Autism Research, Wiley Periodicals, Inc.

2009-01-01

Quality of peer relationships and perceived peer antisocial behavior were examined as moderators of the link between negative parenting and externalizing behavior problems in school from middle childhood to early adolescence. Data on negative parenting (i.e., unilateral parental decision making, low supervision and awareness, and harsh discipline) were collected from 362 parents in the summer preceding the adolescents’ entry into Grade 6. Adolescent reports of positive peer relationships and peer antisocial behavior were assessed in the winter of Grade 7. The outcome measure was teacher report of adolescent externalizing behavior in the spring of Grade 7, controlling for externalizing behavior in Grade 5. High levels of friendship quality and peer group affiliation attenuated the association between unilateral parental decision making and adolescent externalizing behavior in school; this was particularly true when adolescents associated with peers perceived to be low in antisocial behavior. In addition, having low-quality peer relationships and having peers perceived to be highly antisocial further amplified the association between unilateral parental decision making and adolescent externalizing behavior problems. Finally, high levels of friend and peer group antisocial behavior exacerbated the predictiveness of harsh discipline for adolescents’ externalizing behavior. PMID:20209019

The purpose of the study was to extend our understanding of the Kyoto Scale of Psychological Development (KSPD) by comparison with a parent-rated scale, the Kinder Infant Development Scale (KIDS). The participants of this study were 229 children aged 0-4, who were referred to the Developmental Evaluation Center of the National Center for Child Health and Development, due to a suspected developmental disorder/delay. The participants were divided into subgroups, depending on age and overall DQ. For each group separately, correlation analyses were conducted between the Developmental Quotient (DQ) of each KSPD domain and DQ of each KIDS subscale. For high DQ group, in all ages, the KSPD Postural-Motor (P-M) domain DQ demonstrated a high correlation with the KIDS Physical-Motor DQ, and at young ages, it was also found to be moderately or strongly associated with the KIDS Manipulation DQ. For high DQ group, the KSPD Cognitive-Adaptive (C-A) domain DQ was most consistently related to the KIDS Manipulation DQ, and was also moderately correlated with the KIDS Physical-Motor DQ, Receptive Language DQ, Social Relationship with Adults DQ, Discipline DQ, and Feeding DQ, depending on age. For high DQ group, the KSPD Language-Social (L-S) DQ most consistently showed a moderate or high correlation with the KIDS Receptive Language DQ and the Manipulation DQ, and also related to Physical-Motor DQ, Expressive Language DQ, Language Conception DQ, Social Relationship with Adults DQ, and Social Relationship with Children DQ for some age groups. The low DQ group demonstrated stronger relationships on many of the pairs of the DQ of a KSPD subdomain and the DQ of a KIDS subscale, regardless of the type of subdomains and subscales. For high DQ group, the KSPD P-M domain was consistently related to parent-reported physical/motor development, the C-A domain primarily reflected a child's fine motor skills and his/her ability to understand and follow verbal instructions provided by adults, while the L-S domain was associated with parent-reported language ability. For low DQ group, the effect of global delay increased overall correlations between each domain and subscale. Further studies are necessary to replicate the findings in a larger sample including typical children. Copyright © 2015 The Japanese Society of Child Neurology. Published by Elsevier B.V.

2016-03-01

Thirteen percent of newly licensed registered nurses (NLRNs) vacate their first job after 1 year, and 37% report that they feel ready to change jobs. Turnover can lead to consistent and detrimental nursing shortages in nursing units, as well as increased costs for health care systems. A descriptive, prospective, cross-sectional design was used to understand how preceptor role effectiveness and group cohesion affect NLRNs' satisfaction and intent to stay. NLRNs reported high levels of perceived preceptor role effectiveness, group cohesion, and job satisfaction, with only moderate levels of intent to stay. Statistically significant relationships were found among preceptor role effectiveness, job satisfaction, and intent to stay, as well as among group cohesion, job satisfaction, and intent to stay. Preceptor role effectiveness and group cohesion are predictors of NLRNs' level of job satisfaction. Job satisfaction is a predictor of NLRNs' intent to stay. Effective preceptors and positive group cohesion are factors that are important to NLRNs' job satisfaction and intent to stay. Copyright 2016, SLACK Incorporated.

The purpose of this study was to compare self-reported pain and "improvement" of patients with symptomatic, magnetic resonance imaging-confirmed, lumbar disk herniations treated with either high-velocity, low-amplitude spinal manipulative therapy (SMT) or nerve root injections (NRI). This prospective cohort comparative effectiveness study included 102 age- and sex-matched patients treated with either NRI or SMT. Numerical rating scale (NRS) pain data were collected before treatment. One month after treatment, current NRS pain levels and overall improvement assessed using the Patient Global Impression of Change scale were recorded. The proportion of patients, "improved" or "worse," was calculated for each treatment. Comparison of pretreatment and 1-month NRS scores used the paired t test. Numerical rating scale and NRS change scores for the 2 groups were compared using the unpaired t test. The groups were also compared for "improvement" using the χ(2) test. Odds ratios with 95% confidence intervals were calculated. Average direct procedure costs for each treatment were calculated. No significant differences for self-reported pain or improvement were found between the 2 groups. "Improvement" was reported in 76.5% of SMT patients and in 62.7% of the NRI group. Both groups reported significantly reduced NRS scores at 1 month (P = .0001). Average cost for treatment with SMT was Swiss Francs 533.77 (US $558.75) and Swiss Francs 697 (US $729.61) for NRI. Most SMT and NRI patients with radicular low back pain and magnetic resonance imaging-confirmed disk herniation matching symptomatic presentation reported significant and clinically relevant reduction in self-reported pain level and increased global perception of improvement. There were no significant differences in outcomes between NRI and SMT. When considering direct procedure costs, the average cost of SMT was slightly less expensive.

The purpose of this study was to evaluate the effects of a core competency support program on depression and suicidal ideation in adolescents. A quasi-experimental design was employed in this study. Participants for the study were high school students, 27 in the experimental group and 29 in the control group. Data were analyzed using the SPSS/WIN. 14.0 program with X(2) test, t-test, and ANCOVA. Participants in the core competency support program reported decreased depression scores significantly different from those in the control group. Participants in the core competency support program reported decreased suicidal ideation scores, also significantly different from those in the control group. The core competency support program was effective in decreasing depression and suicidal ideation for adolescents. Therefore, this approach is recommended as a suicide prevention strategy for adolescents.

The reported health benefits of Korean red ginseng (KRG) include antioxidant, antitumor, antimutagenic, and immunomodulatory activities; however, the effects on oxidative stress have not yet been evaluated. Therefore, we assessed the effect of KRG on antioxidant enzymes and oxidative stress markers in humans. We conducted a randomized, double-blind, placebo-controlled study with three groups, including placebo, low-dose (3 g/day), and high-dose (6 g/day), which were randomly assigned to healthy subjects aged 20-65 years. Lymphocyte DNA damage, antioxidative enzyme activity, and lipid peroxidation were assessed before and after the 8-week supplementation. Fifty-seven subjects completed the protocol. Plasma superoxide dismutase (SOD) activity after the 8-week KRG supplementation was significantly higher in the low-and high-dose groups compared to baseline. Plasma glutathione peroxidase (GPx) and catalase activities were also increased after the high-dose supplementation. Furthermore, the DNA tail length and tail moment were significantly reduced after the supplementation (low-dose and high-dose), and plasma oxidized low-density lipoprotein (LDL) levels were reduced in low-dose and high-dose groups, but increased in the placebo group. The net changes in oxidized LDL after the supplementation differed significantly between both KRG supplementation groups and the placebo group. Net changes in GPx, SOD and catalase activities, and DNA tail length and tail moment were significantly different between the high-dose group and the placebo group. Additionally, the net changes in urinary 8-epi-PGF(2α) were significantly different between the KRG supplementation groups and the placebo group. KRG supplementation may attenuate lymphocyte DNA damage and LDL oxidation by upregulating antioxidant enzyme activity.
Beneficial effects of Korean red ginseng on lymphocyte DNA damage, antioxidant enzyme activity, and LDL oxidation in healthy participants: a randomized, double-blind, placebo-controlled trial

Background The reported health benefits of Korean red ginseng (KRG) include antioxidant, antitumor, antimutagenic, and immunomodulatory activities; however, the effects on oxidative stress have not yet been evaluated. Therefore, we assessed the effect of KRG on antioxidant enzymes and oxidative stress markers in humans. Methods We conducted a randomized, double-blind, placebo-controlled study with three groups, including placebo, low-dose (3 g/day), and high-dose (6 g/day), which were randomly assigned to healthy subjects aged 20–65 years. Lymphocyte DNA damage, antioxidative enzyme activity, and lipid peroxidation were assessed before and after the 8-week supplementation. Results Fifty-seven subjects completed the protocol. Plasma superoxide dismutase (SOD) activity after the 8-week KRG supplementation was significantly higher in the low-and high-dose groups compared to baseline. Plasma glutathione peroxidase (GPx) and catalase activities were also increased after the high-dose supplementation. Furthermore, the DNA tail length and tail moment were significantly reduced after the supplementation (low-dose and high-dose), and plasma oxidized low-density lipoprotein (LDL) levels were reduced in low-dose and high-dose groups, but increased in the placebo group. The net changes in oxidized LDL after the supplementation differed significantly between both KRG supplementation groups and the placebo group. Net changes in GPx, SOD and catalase activities, and DNA tail length and tail moment were significantly different between the high-dose group and the placebo group. Additionally, the net changes in urinary 8-epi-PGF2α were significantly different between the KRG supplementation groups and the placebo group. Conclusions KRG supplementation may attenuate lymphocyte DNA damage and LDL oxidation by upregulating antioxidant enzyme activity. PMID:22805313

Background American Indians/Alaska Natives (AI/AN) have the highest prevalence of obesity for any racial/ethnic group. Previous studies examining risk factors for obesity have identified excessive sugar-sweetened beverage (SSB) and inadequate water consumption as major risk factors for this population group. The historical scarcity of water in rural Alaska may explain consumption patterns including reliance on SSBs and other packaged drinks. Methods Our study was designed to assess SSB, water and other beverage consumption and attitudes towards consumption in Alaska Native children and adults residing in rural Alaska. During summer 2014, 2 focus groups were conducted employing community members in a small rural village more than 200 air miles west of Fairbanks, Alaska. Interviews were completed with shop owners, Early Head Start and Head Start program instructors (n=7). SSB and total beverage intakes were measured using a modified version of the BEVQ-15, (n=69). Results High rates of SSB consumption (defined as sweetened juice beverages, soda, sweet tea, energy drink or sports drinks) and low rates of water consumption were reported for all age groups in the village. All adolescents and 81% of children reported drinking SSBs at least once per week in the last month, and 48% of adolescents and 29% of younger children reported daily consumption. Fifty-two per cent of adults reported consuming SSBs at least once per week and 20% reported daily consumption. Twenty-five per cent of adolescents reported never drinking water in the past month, and 19% of younger children and 21% of adults did not consume water daily. Conclusion Alaska Native children and adults living in the Interior Alaska consume high amounts of SSBs including energy drinks and insufficient amounts of water. Interventions targeting beverage consumption are urgently needed for the Alaska Native population in rural Alaska. PMID:26928369

Background Group therapy and education and support sessions are used within health care across a range of disciplines such as chronic disease self-management and psychotherapy interventions. However, there are barriers that constrain group attendance, such as mobility, time, and distance. Using videoconferencing may overcome known barriers and improve the accessibility of group-based interventions. Objective The aim of this study was to review the literature to determine the feasibility, acceptability, effectiveness, and implementation of health professional–led group videoconferencing to provide education or social support or both, into the home setting. Methods Electronic databases were searched using predefined search terms for primary interventions for patient education and/or social support. The quality of studies was assessed using the Mixed Methods Appraisal Tool. We developed an analysis framework using hierarchical terms feasibility, acceptability, effectiveness, and implementation, which were informed by subheadings. Results Of the 1634 records identified, 17 were included in this review. Home-based groups by videoconferencing are feasible even for those with limited digital literacy. Overall acceptability was high with access from the home highly valued and little concern of privacy issues. Some participants reported preferring face-to-face groups. Good information technology (IT) support and training is required for facilitators and participants. Communication can be adapted for the Web environment and would be enhanced by clear communication strategies and protocols. A range of improved outcomes were reported but because of the heterogeneity of studies, comparison of these across studies was not possible. There was a trend for improvement in mental health outcomes. Benefits highlighted in the qualitative data included engaging with others with similar problems; improved accessibility to groups; and development of health knowledge, insights, and skills. Videoconference groups were able to replicate group processes such as bonding and cohesiveness. Similar outcomes were reported for those comparing face-to-face groups and videoconference groups. Conclusions Groups delivered by videoconference are feasible and potentially can improve the accessibility of group interventions. This may be particularly useful for those who live in rural areas, have limited mobility, are socially isolated, or fear meeting new people. Outcomes are similar to in-person groups, but future research on facilitation process in videoconferencing-mediated groups and large-scale studies are required to develop the evidence base.

The number of reported child abuse cases is on the increase in Japan. This report describes the testing of an approach to prevention based on a key question: "Do you find any of your children irritating?" The study employed a focus group and a survey. The focus group consisted of 13 mothers who had been severely abusive to their children and were undergoing individual psychotherapy in Tokyo. The survey included 1,538 mothers living with at least one child less than 6 years of age in metropolitan Tokyo. The survey questionnaire asked about mothers' attitudes toward their children and about details and frequency of possibly abusive behavior for their children. All 13 mothers of the focus group reported the experience of feeling their children irritating. They talked extensively and provided many details of their feelings. Of the survey mothers, 3.6% reported feeling their children irritating and showed high scores of abusive behavior. There was a difference in attribution of source of the irritation between these mothers and focus-group mothers. We conclude that the question on irritability is effective in eliciting mothers' feelings and behavior, especially for providing public health nurses with an opportunity for intervention in child abuse.
Involuntary autobiographical memories are relatively more often reported during high cognitive load tasks.

2018-01-01

Recent studies on involuntary autobiographical memories (IAMs) in daily life have shown that they are most frequently reported during daily routines (e.g. while ironing). Such studies have suggested that reporting IAMs may be influenced by the level of the ongoing task demands and availability of cognitive resources. In two studies, we investigated the effects of cognitive load on reporting IAMs. To examine the presumed cognitive load dependency of IAMs, we utilised an often-employed experimental paradigm (Schlagman & Kvavilashvili, 2008) to elicit IAMs under conditions that differed in cognitive load. When performing a vigilance task, participants had to interrupt the task each time they experienced any spontaneous mental contents and write them down. We manipulated the level of cognitive load by either instructing (cognitive load group) or not instructing (control group) participants to perform an additional demanding task. We compared the groups on the number of IAMs and other mental contents (non-IAM contents) recorded, as well as on the frequency of IAMs that was calculated as a proportion of IAMs in all mental contents reported by the participant. We expected that if reporting IAMs depends on the level of cognitive demands, then we should observe lower frequency of IAMs in the cognitive load group compared to the control group. Consistently across studies, we observed a lower number of IAMs and non-IAM contents in the cognitive load group. However, IAMs unexpectedly constituted a higher percentage of all mental contents when participants were cognitively loaded. Further implications of the cognitive load effects for IAMs research and experimental methodology are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.
Difficult incidents and tutor interventions in problem-based learning tutorials.

2009-09-01

Tutors report difficult incidents and distressing conflicts that adversely affect learning in their problem-based learning (PBL) groups. Faculty development (training) and peer support should help them to manage this. Yet our understanding of these problems and how to deal with them often seems inadequate to help tutors. The aim of this study was to categorise difficult incidents and the interventions that skilled tutors used in response, and to determine the effectiveness of those responses. Thirty experienced and highly rated tutors in our Year 1 and 2 medical curriculum took part in semi-structured interviews to: identify and describe difficult incidents; describe how they responded, and assess the success of each response. Recorded and transcribed data were analysed thematically to develop typologies of difficult incidents and interventions and compare reported success or failure. The 94 reported difficult incidents belonged to the broad categories 'individual student' or 'group dynamics'. Tutors described 142 interventions in response to these difficult incidents, categorised as: (i) tutor intervenes during tutorial; (ii) tutor gives feedback outside tutorial, or (iii) student or group intervenes. Incidents in the 'individual student' category were addressed relatively unsuccessfully (effective < 50% of the time) by response (i), but with moderate success by response (ii) and successfully (> 75% of the time) by response (iii). None of the interventions worked well when used in response to problems related to 'group dynamics'. Overall, 59% of the difficult incidents were dealt with successfully. Dysfunctional PBL groups can be highly challenging, even for experienced and skilled tutors. Within-tutorial feedback, the treatment that tutors are most frequently advised to apply, was often not effective. Our study suggests that the collective responsibility of the group, rather than of the tutor, to deal with these difficulties should be emphasised.

The objective of this study is to evaluate the effectiveness of a self-help coping intervention in reducing intrusive negative thoughts while waiting for cancer genetic risk information. Between August 2007 and November 2008, 1958 new referrals for cancer genetic risk assessment were invited to participate in a randomised trial. The control group received standard information. The intervention group received this information plus a written self-help coping leaflet. The primary outcome measure was the intrusion subscale of the Impact of Event Scale. The intervention significantly reduced intrusive thoughts during the waiting period in those reporting moderate baseline levels of intrusion (p = 0.03). Following risk provision, those in the intervention group reporting low and moderate intrusive worries at baseline reported less intrusive thoughts than those in the control group (p = 0.04 and p = 0.03, respectively). The intervention had no adverse impact in the sample as a whole. Participants in the intervention group with high baseline avoidance and negative affect scores were significantly more likely to remain in the study than those in the control group (p = 0.05 and p = 0.004). Findings that the intervention both reduced distress in those with moderate levels of distress and had no adverse effects following notification of cancer genetic risk suggest that this simple intervention can be implemented across a range of oncology settings involving periods of waiting and uncertainty. The intervention may also reduce the number of individuals dropping out of cancer genetic risk assessment or screening. However, those with clinically high levels of psychological distress are likely to require a more intensive psychological intervention. Copyright © 2012 John Wiley & Sons, Ltd.
Did the reporting of prognostic studies of tumour markers improve since the introduction of REMARK guideline? A comparison of reporting in published articles

Although biomarkers are perceived as highly relevant for future clinical practice, few biomarkers reach clinical utility for several reasons. Among them, poor reporting of studies is one of the major problems. To aid improvement, reporting guidelines like REMARK for tumour marker prognostic (TMP) studies were introduced several years ago. The aims of this project were to assess whether reporting quality of TMP-studies improved in comparison to a previously conducted study assessing reporting quality of TMP-studies (PRE-study) and to assess whether articles citing REMARK (citing group) are better reported, in comparison to articles not citing REMARK (not-citing group). For the POST-study, recent articles citing and not citing REMARK (53 each) were identified in selected journals through systematic literature search and evaluated in same way as in the PRE-study. Ten of the 20 items of the REMARK checklist were evaluated and used to define an overall score of reporting quality. The observed overall scores were 53.4% (range: 10%-90%) for the PRE-study, 57.7% (range: 20%-100%) for the not-citing group and 58.1% (range: 30%-100%) for the citing group of the POST-study. While there is no difference between the two groups of the POST-study, the POST-study shows a slight but not relevant improvement in reporting relative to the PRE-study. Not all the articles of the citing group, cited REMARK appropriately. Irrespective of whether REMARK was cited, the overall score was slightly higher for articles published in journals requesting adherence to REMARK than for those published in journals not requesting it: 59.9% versus 51.9%, respectively. Several years after the introduction of REMARK, many key items of TMP-studies are still very poorly reported. A combined effort is needed from authors, editors, reviewers and methodologists to improve the current situation. Good reporting is not just nice to have but is essential for any research to be useful. PMID:28614415
Modifying the 'Positive Parenting Program' for parents with intellectual disabilities.

Glazemakers, I; Deboutte, D

2013-07-01

Many parents with intellectual disabilities (ID) want and/or need professional guidance and support to learn skills and strategies to prevent and manage child behaviour problems. However, the available support is rarely suitable, and suitable support is rarely available. The aim of this study was to determine whether a popular mainstream parenting training programme, known as 'Group Triple P' (Positive Parenting Program), could be successfully modified for this parent group. A pilot study was undertaken to determine whether a modified version of Group Triple P would engage and retain parents with ID. A non-experimental, pre-test post-test study, involving a total of 30 parents with ID, was then undertaken to obtain preliminary efficacy data. Parent engagement and participation levels were high. No parent 'dropped out' of the programme. After completing the modified Group Triple P programme, parents reported a decrease in psychological distress, maladaptive parenting and child conduct problems. Parents reported high levels of satisfaction with the information and support they received. Research-informed adaptation of mainstream behavioural family interventions, such as Group Triple P, could make 'suitable support' more readily available, and more engaging for parents with ID. © 2012 The Authors.

High early life stress and aberrant amygdala activity: risk factors for elevated neuropsychiatric symptoms in HIV+ adults.

2017-06-01

Relative to HIV-negative adults, HIV+ adults report elevated levels of early life stress (ELS). In non-HIV samples, high ELS has been linked to abnormalities in brain structure and function, as well as increased risk of neuropsychiatric symptoms. Yet, little is known about the neural effects of high ELS, and their relation to elevated neuropsychiatric symptoms, in HIV+ adults. Recent studies have revealed combined effects of HIV and high ELS on amygdala morphometry. Aberrant amygdala activity is prominently implicated in studies of neuropsychiatric symptomology in non-HIV samples. Hence, this preliminary study examined: 1) the combined effects of HIV and high ELS on amygdala activity, and 2) the relation between amygdala activity and neuropsychiatric symptoms in HIV+ adults. We included 28 HIV+ adults and 25 demographically-matched HIV-negative control (HC) adults. ELS exposure was quantified using a retrospective ELS questionnaire, which defined four groups: HIV+ Low-ELS (N = 15); HIV+ High-ELS (N = 13); HC Low-ELS (N = 16); and HC High-ELS (N = 9). Participants completed a battery of neuropsychiatric measures. BOLD fMRI assessed amygdala reactivity during explicit observation of fearful/angry faces. High-ELS participants demonstrated reduced levels of amygdala reactivity relative to Low-ELS participants. HIV+ High-ELS participants reported higher levels of neuropsychiatric symptoms than all other groups. In the HIV+ group, lower amygdala responses were associated with higher neuropsychiatric symptoms, particularly depression, anxiety, and alexithymia. Collectively, these results suggest that high ELS exposure is a significant risk factor for neuropsychiatric symptoms in HIV+ adults. Furthermore, our results implicate ELS-related abnormalities in amygdala activity in the etiology of neuropsychiatric symptoms in HIV+ adults.
Merit-Based Incentive Payment System Participation: Radiologists Can Run but Cannot Hide.

To optimize the flexibility and relevancy of its Merit-Based Incentive Payment System (MIPS), CMS exempts selected physicians and groups from participation and grants others relaxed reporting requirements. We assess the practical implications of such special status determinations. For a random sample of 1,000 Medicare-participating radiologists, the CMS MIPS Participation Lookup Tool was manually searched. Individual radiologists' and associated groups' participation requirements and special statuses were assessed. Although only 55% of radiologists were required to participate in MIPS as individuals when considering only one associated taxpayer identification number (TIN), 83% were required to participate as individuals when considering all associated TINs. When using the group reporting option, 97% of radiology groups were required to participate. High participation requirements persisted across generalist and subspecialist radiologists, small and rural, and both academic and nonacademic practices. Non-patient-facing and hospital-based statuses were assigned to high fractions of individual radiologists (91% and 71%, respectively), but much lower fractions of group practices (72% and 25%). Rural and health professional shortage area statuses were assigned to higher percentages of groups (27% and 39%) than individuals (13% and 23%). Small practice status was assigned to 22% of individuals versus 16% of groups. Although not apparent if only considering individual radiologist-TIN combinations, the overwhelming majority of radiologists will be required to participate in MIPS, at the individual or group level. Radiology groups are strongly encouraged to review their physicians' MIPS participation requirements and special statuses to ensure optimal performance scores and payment bonuses.

Interventions to promote sun safety in the U.K. construction sector are warranted given the high incidence of skin cancer attributable to sun exposure relative to other occupational groups. To evaluate change in sun safety knowledge and practices among construction workers in response to an educational intervention. A baseline questionnaire was administered, followed by a bespoke sector-specific DVD-based intervention. At 12-month follow-up, participants completed a further questionnaire. Analyses were conducted on a sample of 120 workers (intervention group, n = 70; comparison group, n = 50). At follow-up, the proportion of intervention group participants that reported correct sun safety knowledge was not significantly greater than at baseline. However, the intervention group demonstrated significant positive change on 9 out of 10 behavioural measures, the greatest change being use of a shade/cover when working in the sun followed by regularly checking skin for moles or unusual changes. Exposure to this intervention was linked to some specific positive changes in construction workers' self-reported sun safety practices. These findings highlight the potential for educational interventions to contribute to tackling skin cancer in the UK construction sector. The findings support the development of bespoke educational interventions for other high-risk outdoor worker groups. © The Author 2015.

2003-01-01

Radical prostatectomy has recently been shown to prolong cancer-specific survival compared to watchful waiting in patients with localized prostate cancer. Most patients who seek medical advice for this disease are treated in hospitals in which the operation is performed relatively infrequently. The aim of this study is to report the oncological outcome at intermediate- to long-term follow-up after radical prostatectomy performed in a community hospital. A total of 148 patients underwent radical prostatectomy at Ryhov County Hospital between 1985 and 1997. Patients without T3 tumours, prostate-specific antigen (PSA) >10 ng/ml or poorly differentiated tumours were judged to be in a low-risk group, those with one risk factor to be in an intermediate group and those with two or more factors to be in a high-risk group. The projected biochemical disease free- and cancer-specific survival rates were compared between these risk groups. Median follow-up was 96 months for surviving patients. Patients in the low- and intermediate risk groups had equal 10-year PSA-free survival rates of 68.8%, while that in the high-risk group was only 19.3% (9-year data). Corresponding cancer-specific survival rates were 93% and 84%, respectively. The oncological outcome seems comparable to that reported in the literature, even when the operation is performed in a low-volume community-based setting.

Not only are childhood onset offenders at high risk of becoming serious persistent offenders, they are also at high risk of becoming victimized themselves. Furthermore, studies in the general population suggest that a combined perpetrator-victim group can be distinguished from a perpetrator-only and a victim-only group on individual and family risk factors. The current study investigated the co-occurrence of offending and victimization among first-time arrestees and the 2-year predictive value of previously found clusters of dynamic risk factors of offending. Childhood first-time arrestees ( N = 308; M age = 10.3, SD = 1.45) were clustered into three groups based on dynamic risk factors of offending in the individual, peer, school, and family domains: a pervasive high, an externalizing intermediate, and a low problem group. Police records and self-report data on re-offending and victimization of these children were collected over a 2-year follow-up period. Compared with the low problem group, the prevalence of re-offending was higher in both the externalizing intermediate group and the pervasive high group. The pervasive high group was most likely to display co-occurring future antisocial behavior and victimization. These findings emphasize that attention should be paid to victimization in addition to future antisocial behavior, especially if additional internalizing and family problems are present. Furthermore, the differences in re-offending and victimization between subgroups of childhood onset offenders stress the need for specific interventions tailored to the risk profile of a child.

The aim of the study was to compare the pain-relieving effect and the time spent in the recovery ward after treatment with high-frequency, high-intensity transcutaneous electrical nerve stimulation (TENS) or intravenous (IV) conventional pharmacological treatment after surgical abortion. Two-hundred women who underwent surgical abortion and postoperatively reported a visual analogue scale (VAS) pain score3 were included. The patients were randomised to TENS or conventional pharmacological treatment for their postoperative pain. The TENS treatment was given with a stimulus intensity between 20 and 60 mA during 1 min and repeated once if insufficient pain relief (VAS3). In the conventional pharmacological treatment group, a maximum dose of 100 microg fentanyl was given IV. There was no difference between the groups with regard to pain relief according to the VAS pain score (TENS=VAS 1.3 vs. IV opioids=VAS 1.6; p=0.09) upon discharge from the recovery ward. However, the patients in the TENS group spent shorter time (44 min) in the recovery ward than the conventional pharmacological treatment group (62 min; p<0.0001). The number of patients who needed additional analgesics in the recovery ward was comparable in both groups, as was the reported VAS pain score upon leaving the hospital (TENS=2.0 vs. conventional pharmacological treatment=1.8, NS). These results suggest that the pain-relieving effect of TENS seems to be comparable to conventional pharmacological treatment with IV opioids. Hence, TENS may be a suitable alternative to conventional pain management with IV opioids after surgical abortion. Copyright 2009 International Association for the Study of Pain.

Through their work midwives may experience distressing events that fulfil criteria for trauma. However, there is a paucity of research examining the impact of these events, or what is perceived to be helpful/unhelpful by midwives afterwards. To investigate midwives' experiences of traumatic perinatal events and to provide insights into experiences and responses reported by midwives with and without subsequent posttraumatic stress symptoms. Semi-structured telephone interviews were conducted with a purposive sample of midwives following participation in a previous postal survey. 35 midwives who had all experienced a traumatic perinatal event defined using the Diagnostic and Statistical Manual of Mental Disorders (version IV) Criterion A for posttraumatic stress disorder were interviewed. Two groups of midwives with high or low distress (as reported during the postal survey) were purposefully recruited. High distress was defined as the presence of clinical levels of PTSD symptomatology and high perceived impairment in terms of impacts on daily life. Low distress was defined as any symptoms of PTSD present were below clinical threshold and low perceived life impairment. Interviews were analysed using template analysis, an iterative process of organising and coding qualitative data chosen for this study for its flexibility. An initial template of four a priori codes was used to structure the analysis: event characteristics, perceived responses and impacts, supportive and helpful strategies and reflection of change over time codes were amended, integrated and collapsed as appropriate through the process of analysis. A final template of themes from each group is presented together with differences outlined where applicable. Event characteristics were similar between groups, and involved severe, unexpected episodes contributing to feeling 'out of a comfort zone.' Emotional upset, self-blame and feelings of vulnerability to investigative procedures were reported. High distress midwives were more likely to report being personally upset by events and to perceive all aspects of personal and professional lives to be affected. Both groups valued talking about the event with peers, but perceived support from senior colleagues and supervisors to be either absent or inappropriate following their experience; however, those with high distress were more likely to endorse this view and report a perceived need to seek external input. Findings indicate a need to consider effective ways of promoting and facilitating access to support, at both a personal and organisational level, for midwives following the experience of a traumatic perinatal event.

Background Forming specific health plans can help translate good intentions into action. Mobile text reminders can further enhance the effects of planning on behavior. Objective Our aim was to explore the combined impact of a Web-based, fully automated planning tool and mobile text reminders on intention to change saturated fat intake, self-reported saturated fat intake, and portion size changes over 4 weeks. Methods Of 1013 men and women recruited online, 858 were randomly allocated to 1 of 3 conditions: a planning tool (PT), combined planning tool and text reminders (PTT), and a control group. All outcome measures were assessed by online self-reports. Analysis of covariance was used to analyze the data. Results Participants allocated to the PT (meansat urated fat 3.6, meancopingplanning 3) and PTT (meansaturatedfat 3.5, meancopingplanning 3.1) reported a lower consumption of high-fat foods (F 2,571 = 4.74, P = .009) and higher levels of coping planning (F 2,571 = 7.22, P < .001) than the control group (meansat urated f at 3.9, meancopingplanning 2.8). Participants in the PTT condition also reported smaller portion sizes of high-fat foods (mean 2.8; F 2, 569 = 4.12, P = .0) than the control group (meanportions 3.1). The reduction in portion size was driven primarily by the male participants in the PTT (P = .003). We found no significant group differences in terms of percentage saturated fat intake, intentions, action planning, self-efficacy, or feedback on the intervention. Conclusions These findings support the use of Web-based tools and mobile technologies to change dietary behavior. The combination of a fully automated Web-based planning tool with mobile text reminders led to lower self-reported consumption of high-fat foods and greater reductions in portion sizes than in a control condition.

2017-06-01

Prevalence estimates of HIV-associated neurocognitive disorders (HAND) may be inflated. Estimates are determined via cohort studies in which participants may apply suboptimal effort on neurocognitive testing, thereby inflating estimates. Additionally, fluctuating HAND severity over time may be related to inconsistent effort. To address these hypotheses, we characterized effort in the Multicenter AIDS Cohort Study. After neurocognitive testing, 935 participants (525 HIV- and 410 HIV+) completed the visual analog effort scale (VAES), rating their effort from 0% to 100%. Those with <100% then indicated the reason(s) for suboptimal effort. K-means cluster analysis established 3 groups: high (mean = 97%), moderate (79%), and low effort (51%). Rates of HAND and other characteristics were compared between the groups. Linear regression examined the predictors of VAES score. Data from 57 participants who completed the VAES at 2 visits were analyzed to characterize the longitudinal relationship between effort and HAND severity. Fifty-two percent of participants reported suboptimal effort (<100%), with no difference between serostatus groups. Common reasons included "tired" (43%) and "distracted" (36%). The lowest effort group had greater asymptomatic neurocognitive impairment and minor neurocognitive disorder diagnosis (25% and 33%) as compared with the moderate (23% and 15%) and the high (12% and 9%) effort groups. Predictors of suboptimal effort were self-reported memory impairment, African American race, and cocaine use. Change in effort between baseline and follow-up correlated with change in HAND severity. Suboptimal effort seems to inflate estimated HAND prevalence and explain fluctuation of severity over time. A simple modification of study protocols to optimize effort is indicated by the results.

Falls are associated with morbidity, loss of independence, and mortality. While land-based group exercise and Tai Chi programs reduce the risk of falls, aquatic therapy may allow patients to complete balance exercises with less pain and fear of falling; however, limited data exist. The objective of the study was to pilot the implementation of an aquatic group based on Ai Chi principles (Aquabalance) and to evaluate the safety, intervention acceptability, and intervention effect sizes. Pilot observational cohort study. Forty-two outpatients underwent a single 45-minute weekly group aquatic Ai Chi-based session for eight weeks (Aquabalance). Safety was monitored using organizational reporting systems. Patient attendance, satisfaction, and self-reported falls were also recorded. Balance measures included the Timed Up and Go (TUG) test, the Four Square Step Test (FSST), and the unilateral Step Tests. Forty-two patients completed the program. It was feasible to deliver Aquabalance, as evidenced by the median (IQR) attendance rate of 8.0 (7.8, 8.0) out of 8. No adverse events occurred and participants reported high satisfaction levels. Improvements were noted on the TUG, 10-meter walk test, the Functional Reach Test, the FSST, and the unilateral step tests (p < 0.05). The proportion of patients defined as high falls risk reduced from 38% to 21%. The study was limited by its small sample size, single-center nature, and the absence of a control group. Aquabalance was safe, well-attended, and acceptable to participants. A randomized controlled assessor-blinded trial is required.

To evaluate the psychological adjustment of young adults with IDDM in comparison with similarly aged individuals without chronic illness. An onset cohort of young adults (n = 57), ages 19-26 years, who have been followed over a 10-year period since diagnosis, was compared with a similarly aged group of young adults identified at the time of a moderately severe, acute illness (n = 54) and followed over the same 10-year period. The groups were assessed at 10-year follow-up in terms of 1) sociodemographic indices (e.g., schooling, employment, delinquent activities, drug use), 2) psychiatric symptoms, and 3) perceived competence. In addition, IDDM patients were examined for longitudinal change in adjustment to diabetes. The groups differed only minimally in terms of sociodemographic indices, with similar rates of high school graduation, post-high school education, employment, and drug use. The IDDM group reported fewer criminal convictions and fewer non-diabetes-related illness episodes than the comparison group. There were no differences in psychiatric symptoms. However, IDDM patients reported lower perceived competence, with specific differences found on the global self-worth, sociability, physical appearance, being an adequate provider, and humor subscales. The IDDM patients reported improving adjustment to their diabetes over the course of the 10-year follow-up. Overall, the young adults with IDDM appeared to be as psychologically well adjusted as the young adults without a chronic illness. There were, however, indications of lower self-esteem in the IDDM patients that could either portend or predispose them to risk for future depression or other difficulties in adaptation.

Previous studies assessing efficacy of support groups for patients with inflammatory bowel disease showed mixed results in terms of attendance and overall effectiveness. In this study, researchers evaluated the use of an ongoing open psychoeducational support group for adult patients with inflammatory bowel disease in an outpatient tertiary setting. The sample consisted of 18 adults who have attended more than 2 meetings of the support group. Topics addressed in the support group include complementary medicine, diet and nutrition, the psychological impact of inflammatory bowel disease, medication and side effects, and insurance/disability. Participants were asked to complete the Client Satisfaction Questionnaire, Multidimensional Support Scale, 11 general demographic questions, and a brief open-ended qualitative questionnaire developed by the researchers. Results demonstrated that participants reported very high satisfaction with the support group and rated the adequacy of peer support from others with inflammatory bowel disease higher than support from family/friends and professionals. A majority of group members reported joining the group for mutual support and education; this expectation was met through the psychoeducational structure of the group. This study demonstrates the potential for success of an ongoing psychoeducational inflammatory bowel disease support group for adult patients and their caregivers.

To determine the effect of a standardized 6-week self-defense program on the incidence of sexual assault in adolescent high school girls in an urban slum in Nairobi, Kenya. Population-based survey of 522 high school girls in the Korogocho-Kariobangi locations in Nairobi, Kenya, at baseline and 10 months later. Subjects were assigned by school attended to either a "No Means No Worldwide" self-defense course (eight schools; N = 402) or to a life-skills class (two schools; N = 120). Both the intervention and the life-skills classes were taught in the schools by trained instructors. Participants were administered the same survey at baseline and follow-up. A total of 522 girls (mean age, 16.7 ± 1.5 years; range, 14-21 years) completed surveys at baseline, and 489 at 10-month follow-up. At baseline, 24.5% reported sexual assault in the prior year, with the majority (90%) reporting assault by someone known to them (boyfriend, 52%; relative, 17%; neighbor, 15%; teacher or pastor, 6%). In the self-defense intervention group, the incidence of sexual assault decreased from 24.6% at baseline to 9.2% at follow-up (p < .001), in contrast to the control group, in which the incidence remained unchanged (24.2% at baseline and 23.1% at follow-up; p = .10). Over half the girls in the intervention group reported having used the self-defense skills to avert sexual assault in the year after the training. Rates of disclosure increased in the intervention group, but not in controls. A standardized 6-week self-defense program is effective in reducing the incidence of sexual assault in slum-dwelling high school girls in Nairobi, Kenya.

To (1) assess memorability and treatment fidelity of pre-operative physiotherapy education prior to elective upper abdominal surgery and, (2) to explore patient opinions on pre-operative education. Mixed-methods analysis of a convenience sample within a larger parallel-group, double-blinded, randomised controlled trial with concealed allocation and intention-to-treat analysis. Tertiary Australian hospital. Twenty-nine patients having upper abdominal surgery attending pre-admission clinic within six-weeks of surgery. The control group received an information booklet about preventing pulmonary complications with early ambulation and breathing exercises. The experimental group received an additional face-to-face 30-minute physiotherapy education and training session on pulmonary complications, early ambulation, and breathing exercises. Primary outcome was proportion of participants who remembered the taught breathing exercises following surgery. Secondary outcomes were recall of information sub-items and attainment of early ambulation goals. These were measured using standardised scoring of a semi-scripted digitally-recorded interview on the 5th postoperative day, and the attainment of early ambulation goals over the first two postoperative days. Experimental group participants were six-times more likely to remember the breathing exercises (95%CI 1.7 to 22) and 11-times more likely (95%CI 1.6 to 70) to report physiotherapy as the most memorable part of pre-admission clinic. Participants reported physiotherapy education content to be detailed, interesting, and of high value. Some participants reported not reading the booklet and professed a preference for face-to-face information delivery. Face-to-face pre-operative physiotherapy education and training prior to upper abdominal surgery is memorable and has high treatment fidelity. ACTRN-12613000664741.

Levels of mental distress are high in patients with substance use disorders (SUD) and investigation of correlates may broaden our understanding of this comorbidity. We investigated self-reported symptoms of mental distress among individuals entering either outpatient opioid maintenance treatment (OMT) or other inpatient SUD treatment and related factors, with a particular focus on perceived self-control. A cross-sectional study including substance users (n = 548; mean age 34 years; 27% women) entering treatment at 21 different treatment-centers across Norway, interviewed between December 2012 and April 2015. Symptoms of mental distress were assessed with Global Symptom Index (GSI) score. Adjusted relative risk ratios (RRR) with 95% confidence intervals (CI) were estimated through multinomial logistic regression. More than half of the participants in both treatment groups reported mental distress (GSI) above clinical cut-off. The use of alcohol and exposure to violence were associated with increased likelihood of high GSI for both patient groups. Also, lower perceived self-control was related to high GSI in both treatment groups. Symptoms of mental distress were equally common among patients entering OMT and those entering other inpatient SUD treatment, even if the patients differed on a number of clinical characteristics. Use of alcohol and exposure to violence were associated with more mental distress in both groups. Perceived self-control also appeared to be important when explaining symptoms of mental distress among these SUD patients.

We report new measurements of doubly ionized iron group element spectra, important in the analysis of B-type (hot) stars whose spectra they dominate. These measurements include Co III and Cr III taken with the Imperial College VUV Fourier transform (FT) spectrometer and measurements of Co III taken with the normal incidence vacuum spectrograph at NIST, below 135 nm. We report new Fe III grating spectra measurements to complement our FT spectra. Work towards transition wavelengths, energy levels and branching ratios (which, combined with lifetimes, produce oscillator strengths) for these ions is underway.

This study tested the spectrum hypothesis, which posits that children and adolescents with high functioning autism (HFA) differ quantitatively but not qualitatively from typically developing peers on self-reported temperament. Temperament refers to early-appearing, relatively stable behavioral and emotional tendencies, which relate to maladaptive behaviors across clinical populations. Quantitatively, participants with HFA (N = 104, aged 10-16) self-reported less surgency and more negative affect but did not differ from comparison participants (N = 94, aged 10-16) on effortful control or affiliation. Qualitatively, groups demonstrated comparable reliability of self-reported temperament and associations between temperament and parent-reported behavior problems. These findings support the spectrum hypothesis, highlighting the utility of self-report temperament measures for understanding individual differences in comorbid behavior problems among children and adolescents with HFA.

Cross sectional study of 888 participants (aged 41 ± 11 years, 76% women), who answered a survey about cardiovascular risk factors. Body mass index, waist, blood pressure and total cholesterol (TC) by capillary method were determined. Self reported prevalence of risk factors were as follows: 19% of participants had high blood pressure, 30% hypercholesterolemia, 6% diabetes, 41% smoked, 88% were sedentary and 26% had a family history of cardiovascular diseases. Five percent of participants did not have any risk factor, 20% had one risk factor, 32% had two and 43% had three or more. The highest frequency of lack of awareness was about blood glucose values. A high blood cholesterol level was found in 27% of those reporting normal cholesterol levels. Likewise, a high body mass index was found in 18% of those reporting a normal weight. The prevalence of cardiovascular risk factors in this group of participants is similar to that found in the last national health survey in Chile. Noteworthy is the lack of awareness about these risk factors.

Severe airways obstruction and bronchiolitis obliterans have been reported in microwave popcorn production workers and attributed to inhalation of flavoring agents. We investigated whether exposure to flavoring agents is associated with airways inflammation in popcorn production workers. Fifty-nine workers with high exposures and 22 patients with low exposures to flavoring vapors completed a questionnaire, spirometry, and sputum induction. Sputum cell counts were categorized as "high" if greater than (and "low" if less than or equal to) the median cell counts of a healthy external control group (n = 24). We compared high- and low-exposure groups as well as all workers with control subjects. Neutrophil concentrations in nonsmoking workers were significantly higher than those of the healthy nonsmoking control group (p < 0.05). The smoking-adjusted odds ratio for high neutrophil count (> 1.63 x 10(5)/mL) was 3.8 (95% confidence interval, 1.3 to 11.5) in the high-exposure group compared with the low-exposure group. Sputum interleukin-8 and eosinophil cationic protein levels were higher in high-exposure workers than in low-exposure workers (p < 0.05). For the worker group, mean values of FEV1 percentage of predicted and FEV1/FVC percentage of predicted were > 95%. There were no relationships between sputum characteristics and the presence of airways obstruction. High exposure to popcorn flavoring agents is associated with neutrophilic airway inflammation in popcorn production workers. These data provide further evidence that popcorn production workers face a significant occupational hazard through exposure to flavoring agents.

Adolescents are known to have high risk factors for sleep disorders, yet the youth rates of sleep disturbances are unknown. This study aimed to determine the prevalence of sleep disorders among New Zealand high school students. The Auckland Sleep Questionnaire (ASQ) was administered to high school students at six schools in the North Island. Schools were chosen to reflect a range of ethnicities and school deciles, which identify the socioeconomic status of households in the school catchment area. A total of 1388 students completed the ASQ. The median age was 17 years (range 14-23) and females represented 43.5% (n=604) of the total group. A total of 37.2% of the students surveyed reported having significant sleep symptoms lasting longer than one month. Depression and anxiety were present in 51.7% and 44.8% of students reporting a sleep problem, respectively. A moderate correlation was observed between sleep problems and depression (r=0.34, p<0.01), and sleep problems and anxiety (r=0.31, p<0.01). Problem alcohol use and other substance use were more common in students with sleep symptoms (12.2% and 5.5% respectively). No difference was found in the rate of sleep problems reported by different ethnic groups. A considerable proportion of students surveyed reported significant sleep symptoms. This study has the potential to aid physicians within New Zealand in better appreciating the burden of sleep disorders faced by young people and in effectively assessing and managing different causes of sleep symptoms in this demographic.

To explore the geographical distribution of mortality due to intimate partner violence (IPV) and reports of IPV according to the gender development index (GDI) of Spanish provinces. We performed an ecological study, based on GDI by provinces, of deaths from IPV and official complaints of IPV made by women between 1997 and 2004. The sources were the "Report on Human Capital and Human Development in Spain", the "Home Affairs Statistics Yearbook", and the web page of the Federation of Separated and Divorced Women. Provinces were divided into 2 groups according to whether their GDI score was above or below the mean GDI score for Spain (0.895). Mortality rates by age and rates of official complaints of IPV were calculated for the two groups of provinces (high and low GDI). Relative risks and their confidence intervals were calculated to analyze the risk of dying from or reporting IPV in low GDI provinces compared with that in high GDI provinces. The risk of death due to IPV was higher in women living in low GDI provinces than in those living in high GDI provinces (RR = 1.328; 95% CI, 1.253-1.406). Furthermore, the risk of reporting IPV was higher in low GDI provinces than in high GDI provinces (RR = 1.468; 95% CI, 1.462-1.474). Despite the trend to develop IPV strategies focused on individual causes, our results suggest that to tackle this problem, strategies for promoting gender equity in Spain are required.

Posttraumatic Stress Disorder (PTSD) and mild traumatic brain injury (mTBI) are common comorbidities during military deployment that affect emotional brain processing, yet few studies have examined the independent effects of mTBI and PTSD. The purpose of this study was to examine distinct differences in neural responses to emotional faces in mTBI and PTSD. Twenty-one soldiers reporting high PTSD symptoms were compared to 21 soldiers with low symptoms, and 16 soldiers who reported mTBI-consistent injury and symptoms were compared with 16 soldiers who did not sustain an mTBI. Participants viewed emotional face expressions while their neural activity was recorded (via event-related potentials) prior to and following deployment. The high-PTSD group displayed increased P1 and P2 amplitudes to threatening faces at post-deployment compared to the low-PTSD group. In contrast, the mTBI group displayed reduced face-specific processing (N170 amplitude) to all facial expressions compared to the no-mTBI group. Here, we identified distinctive neural patterns of emotional face processing, with attentional biases towards threatening faces in PTSD, and reduced emotional face processing in mTBI.

Background. High-dose inhaled steroid therapy has been shown to be effective in children and adults with asthma exacerbations. However, few reports are available regarding its efficacy for asthma exacerbations in younger children. Objective. In this study, we administered high-dose nebulized budesonide therapy for mild asthma exacerbations in children < 3 years of age and compared its efficacy and safety with systemic steroid therapy. Methods. This study included children < 3 years old with mild asthma exacerbations. Patients were randomly assigned to two groups: the BIS group was given 1 mg of nebulized budesonide twice daily, and the PSL group received prednisolone 0.5 mg/kg iv three times daily. Days to disappearance of wheezing, days of steroid use, days of oxygen use, serum cortisol level, and incidence of adverse events during treatment were compared between the groups. Result. Wheezing disappeared after an average of five days, and steroids were administered for an average of five days in both groups, with no significant difference in days of oxygen use. Serum cortisol levels at initiation and during the course of treatment remained unchanged in the BIS group, and were decreased in the PSL group; however, the decrease in the latter group was not pathologic. Conclusion. For children < 3 years old with mild asthma exacerbations, high-dose nebulized budesonide therapy is equally as effective as systemic steroid therapy.

Background Establishing the feasibility and validity of implementation fidelity monitoring strategies is an important methodological step in implementing evidence-based interventions on a large scale. Objectives The objective of the study was to examine the reliability and validity of the Fidelity Checklist, a measure designed to assess group leader adherence and competence delivering a parent training intervention (the Chicago Parent Program) in child care centers serving low-income families. Method The sample included 9 parent groups (12 group sessions each), 12 group leaders, and 103 parents. Independent raters reviewed 106 audiotaped parent group sessions and coded group leaders’ fidelity on the Adherence and Competence Scales of the Fidelity Checklist. Group leaders completed self-report adherence checklists and a measure of parent engagement in the intervention. Parents completed measures of consumer satisfaction and child behavior. Results High interrater agreement (Adherence Scale = 94%, Competence Scale = 85%) and adequate intraclass correlation coefficients (Adherence Scale = .69, Competence Scale = .91) were achieved for the Fidelity Checklist. Group leader adherence changed over time, but competence remained stable. Agreement between group leader self-report and independent ratings on the Adherence Scale was 85%; disagreements were more frequently due to positive bias in group leader self-report. Positive correlations were found between group leader adherence and parent attendance and engagement in the intervention and between group leader competence and parent satisfaction. Although child behavior problems improved, improvements were not related to fidelity. Discussion The results suggest that the Fidelity Checklist is a feasible, reliable, and valid measure of group leader implementation fidelity in a group-based parenting intervention. Future research will be focused on testing the Fidelity Checklist with diverse and larger samples and generalizing to other group-based interventions using a similar intervention model.
