At national level in England and Wales, infant mortality rates fell rapidly from the early 1970s and into the 1980s. Subnational areas have also experienced a reduction in levels of infant mortality. While rates continued to fall to 2006, the rate of reduction has slowed. Although the Government Office Regions Yorkshire and The Humber, the North West and the West Midlands and the Office for National Statistics local authority types Cities and Services and London Cosmopolitan have experienced relatively large absolute reductions in infant mortality, their rates remained high compared with the national average. Within all regions and local authority types, a strong relationship was found between ward level deprivation and infant mortality rates. Nevertheless, levels of infant mortality declined over time even in the most deprived areas with a narrowing of absolute differences in rates between areas. Areas in which the level of deprivation eased have experienced greater than average reductions in levels of infant mortality.

Teen dating violence (TDV) is associated with multiple sequelae including substance use. The objective of this study was to determine the prevalence and association between levels of dating violence and substance use among urban adolescents presenting at a pediatric emergency department (ED). As part of standard practice, 282 adolescents were screened for relationship status, producing 135 dating violence screens. Scales from the Revised Conflict Tactics Scale and the Youth Risk Behavior Survey were used to capture variables of interest. Logistic regression was performed to test the influence of levels of dating violence on substance use, while controlling for gender, race, age, sexual orientation, and psychiatric symptoms. Over one-quarter of those teens (27.3%) within a current relationship reported experiencing any dating violence, 26.1% experienced psychological violence, and 11.9% experienced physical violence. Teens experiencing psychological violence were at twice the risk for any substance use (alcohol, marijuana, and tobacco use) and specifically for alcohol and marijuana, whereas no increased risk was found for teens experiencing physical violence. This study contributes to the understanding of TDV within the context of high-risk, urban adolescents presenting at a pediatric ED. Identifying levels of TDV and understanding the association with substance use can provide an important foundation for prevention and early intervention for urban youth.

The aim of the study was to test differences in self-esteem and strength of the body self, body image, comfort with closeness with others and body protection among women reporting high and low intensity of psychological, vasomotor and somatic symptoms of menopause. The sample included 201 women aged 45-55 years. The Menopause Symptom List was used to test the intensity of menopausal symptoms, the Body Self Questionnaire was used to diagnose the body self, and the Rosenberg Self-Esteem Scale was used to examine participants'levels of self-esteem. Differences between women experiencing high and low intensity of symptoms were analyzed using Student's t-test for independent samples. Women experiencing high-intensity psychological, vasomotor and somatic symptoms of menopause showed significantly lower self-esteem and poorer body-self functioning in all its dimensions except for body protection. Women experiencing high-intensity psychological, vasomotor and somatic symptoms of menopause demonstrated poorer functioning of the body self and lower self-esteem.

Daily Affective Experiences Predict Objective Sleep Outcomes among Adolescents

2015-01-01

Summary Adolescence is a sensitive period for changes in both sleep and affect. Although past research has assessed the association between affect and sleep among adolescents, few studies have examined both trait (typical) and day-to-day changes in affect, and fewer still have specifically examined negative social evaluative emotions (NSEE; e.g., embarrassment) in relation to sleep. We examined both between- and within-person variations in daily affect in relation to four objectively-measured sleep outcomes (sleep hours, sleep latency, sleep efficiency, and length of wake bouts) among adolescents. Participants (N = 77 high school students, 42.9% female; M = 14.37 years) wore an actiwatch and completed daily diaries for 3 days. Results of hierarchical linear models (controlling for age, gender, race, ethnicity, parental employment status, income, puberty, and caffeine) indicated that NSEE and high arousal affective experiences generally predicted poor sleep outcomes, whereas low arousal affective experiences were associated with good sleep outcomes. Specifically, at the person level, adolescents reporting higher NSEE had shorter average sleep hours, and those experiencing higher anxiety-nervousness had longer wake bouts. In addition, individuals experiencing more dysphoria (sad, depressed, lonely) had longer average sleep hours and shorter wake bouts, while those experiencing more calmness had shorter sleep latencies. At the within person level, individuals had longer sleep latencies following days that they had experienced high arousal positive affect (e.g., excitement) and had longer wake bouts following days they had experienced more NSEE. Results highlight the detrimental effects of NSEE and high arousal affective states for adolescent sleep. PMID:26365539

Domestic violence in the perinatal period is associated with adverse obstetric outcomes, but evidence is limited on its association with perinatal mental disorders. We aimed to estimate the prevalence and odds of having experienced domestic violence among women with antenatal and postnatal mental disorders (depression and anxiety disorders including post-traumatic stress disorder [PTSD], eating disorders, and psychoses). We conducted a systematic review and meta-analysis (PROSPERO reference CRD42012002048). Data sources included searches of electronic databases (to 15 February 2013), hand searches, citation tracking, update of a review on victimisation and mental disorder, and expert recommendations. Included studies were peer-reviewed experimental or observational studies that reported on women aged 16 y or older, that assessed the prevalence and/or odds of having experienced domestic violence, and that assessed symptoms of perinatal mental disorder using a validated instrument. Two reviewers screened 1,125 full-text papers, extracted data, and independently appraised study quality. Odds ratios were pooled using meta-analysis. Sixty-seven papers were included. Pooled estimates from longitudinal studies suggest a 3-fold increase in the odds of high levels of depressive symptoms in the postnatal period after having experienced partner violence during pregnancy (odds ratio 3.1, 95% CI 2.7-3.6). Increased odds of having experienced domestic violence among women with high levels of depressive, anxiety, and PTSD symptoms in the antenatal and postnatal periods were consistently reported in cross-sectional studies. No studies were identified on eating disorders or puerperal psychosis. Analyses were limited because of study heterogeneity and lack of data on baseline symptoms, preventing clear findings on causal directionality. High levels of symptoms of perinatal depression, anxiety, and PTSD are significantly associated with having experienced domestic violence. High-quality evidence is now needed on how maternity and mental health services should address domestic violence and improve health outcomes for women and their infants in the perinatal period.

1995-04-01

This study examined whether sixth graders' (mean age = 11.86 years) adjustment to the school context (assessed by grades, achievement scores, and disruptive behavior) was affected by factors from both the family context (represented by students' reports of the number of parenting transitions experienced as well as current levels of supervision, acceptance, autonomy granting, and conflict in the family) and the peer context (represented by students' perceptions of peer norms supporting academic excellence). School adjustment was related to the number of parenting transitions experienced, family climate, and peer norms as well as to higher-order relations involving family climate and peer norms such that (a) high grade point averages occurred at only moderate levels of family supervision, (b) achievement scores were positively related to supervision at only low levels of family autonomy granting, and (c) grade point average was positively related to peer norms at only high levels of family acceptance.

The magnitude of stress and associated health consequences experienced by caregivers compromises their ability to effectively provide care to children, especially children with disability. We used latent class analysis of data from the 2010 Ohio Family Health Survey and identified 3 distinct classes of caregivers based on patterns of responses to 15 financial and psychological stresses they experienced. Compared with children residing in households in which caregivers experienced very little or no stress, children with disability were twice as likely to reside with caregivers with high levels of financial stress and almost 3.5 times as likely to reside with caregivers with high levels of financial stress and very high levels of psychological stress than typically developing children. Reducing caregiver stress is a critical step to ensuring the best health outcomes possible for children with disability. We identify the heterogeneity that is present in the population of caregivers by virtue of patterns of responses to various financial and psychological stressors. Children with disability are more likely to live in households in which a greater number of stressors affect caregivers. Different confounders are also associated with the latent classes of stress we identify. This is an important implication when determining the right interventions to target to the right subpopulations.

To compare the effects of a low-carbohydrate diet and a conventional (fat- and calorie-restricted) diet on lipoprotein subfractions and inflammation in severely obese subjects. We compared changes in lipoprotein subfractions and C-reactive protein levels in 78 severely obese subjects, including 86% with either diabetes or metabolic syndrome, who were randomly assigned to either a low-carbohydrate or conventional diet for 6 months. Subjects on a low-carbohydrate diet experienced a greater decrease in large very low-density lipoprotein (VLDL) levels (difference =-0.26 mg/dL, p = .03) but more frequently developed detectable chylomicrons (44% vs 22%, p = .04). Both diet groups experienced similar decreases in the number of low-density lipoprotein (LDL) particles (difference = -30 nmol/L, p = .74) and increases in large high-density lipoprotein (HDL) concentrations (difference = 0.70 mg/dL, p = .63). Overall, C-reactive protein levels decreased modestly in both diet groups. However, patients with a high-risk baseline level (>3 mg/dL, n = 48) experienced a greater decrease in C-reactive protein levels on a low-carbohydrate diet (adjusted difference = -2 mg/dL, p = .005), independent of weight loss. In this 6-month study involving severely obese subjects, we found an overall favorable effect of a low-carbohydrate diet on lipoprotein subfractions and on inflammation in high-risk subjects. Both diets had similar effects on LDL and HDL subfractions. ( Am J Med. 2004;117:398-405.).

2017-01-01

The degree to which anticipated and experienced public stigma contribute to self-stigma remains open to debate, and little research has been conducted into the self-stigma of problem gambling. This study aimed to examine which aspects of anticipated and experienced stigma (if any) predict the anticipated level of public stigma associated with problem gambling and the degree of self-stigma felt by people experiencing problem gambling. An online survey of 177 Australians experiencing problem gambling examined whether aspects of the public characterization of problem gambling, anticipated reactions to problem gamblers, and experiences of devaluation and discrimination predicted anticipated level of public stigma and self-stigma. The study found that self-stigma increases with expectations that the public applies a range of negative stereotypes to people with gambling problems, holds demeaning and discriminatory attitudes toward them, and considers them to lead highly disrupted lives. These variables directly predicted anticipated level of public stigma and indirectly predicted self-stigma. These findings lend weight to conceptualizations of self-stigma as an internalization of actual or anticipated public stigma. They also highlight the need for stigma reduction efforts, particularly those that lower negative stereotyping and prejudicial attitudes, to improve currently low rates of help-seeking amongst people with gambling problems.

Violence against women that is perpetrated by an intimate partner prevails as one of the most widespread human rights violations in virtually all societies of the world. Women in resource-poor countries, in particular those affected by recent war, appear to be at high risk of experiencing partner violence. Although there has been a longstanding assumption that organised violence at a societal level is transmitted to an interpersonal level, little is known about the link between exposure to war and familial violence. We conducted an epidemiological survey in 2010 with 2nd-grade students and their male and female guardians from nine heavily war-affected communities in Northern Uganda employing structured interviews and standardized questionnaires. The present study analysed a subsample of 235 guardian couples from seven rural communities in order to determine the prevalence and predictors of current partner violence experienced by women in the context of the past war. Study results revealed a high prevalence of ongoing partner violence experienced by female partners. In the past year, 80% of women reported at least one type of verbal/psychological abuse, 71% were exposed to at least one type of physical abuse, 52% suffered isolation and 23% fell victim to sexual violence. Findings from linear regression analyses showed that women's prior exposure to war-related traumatic events, women's re-experiencing symptoms and men's level of alcohol-related problems were associated with higher levels of partner violence against women. Differential effects of the predictor variables emerged with respect to different subtypes of partner violence. The findings suggest that partner violence against women constitutes a major problem in rural Northern Uganda. Programmes for the prevention and reduction of partner violence against women need to address high levels of hazardous drinking in men as well as women's prior traumatisation. In addition, different patterns of partner violence should be taken into account. Copyright © 2013 Elsevier Ltd. All rights reserved.

Effects of work environment and job characteristics on the turnover intention of experienced nurses: The mediating role of work engagement.

To assess turnover intention among experienced nurses and explore the effects of work environment, job characteristics and work engagement on turnover intention. The nursing shortage is an urgent concern in China. A high turnover rate of experienced nurses could have serious effects on the quality of care, costs and the efficiency of hospitals. It is crucial to explore the predictors of turnover intention and develop strategies tailored to experienced nurses. A descriptive, cross-sectional survey design. A total of 778 experienced nurses from seven hospitals was surveyed on their work engagement, job characteristics, work environment and turnover intention in March-May 2017. Structural equation modelling was used to test a theoretical model and the hypotheses. The results showed that 35.9% of experienced nurses had high-level turnover intention. The final model explained 50% of the variance in experienced nurses' turnover intention and demonstrated that: (1) work environment was positively associated with higher work engagement and lower turnover intention and work engagement partially mediated the relationship between work environment and turnover intention; and (2) job characteristics were positively related to higher work engagement and lower turnover intention and work engagement fully mediated the relationship between job characteristics and turnover intention. The study confirms the intrinsic and extrinsic motivators on work engagement posited by job demands-resources model. Theory-driven strategies to improve work environment, enhance job characteristics and promote wok engagement are needed to address the nursing shortage and high turnover intention among experienced nurses. © 2018 John Wiley & Sons Ltd.

The association between high levels of cumulative life stress and aberrant resting state EEG dynamics in old age.

PubMed

Marshall, Amanda C; Cooper, Nicholas R

2017-07-01

Cumulative experienced stress produces shortcomings in old adults' cognitive performance. These are reflected in electrophysiological changes tied to task execution. This study explored whether stress-related aberrations in older adults' electroencephalographic (EEG) activity were also apparent in the system at rest. To this effect, the amount of stressful life events experienced by 60 young and 60 elderly participants were assessed in conjunction with resting state power changes in the delta, theta, alpha, and beta frequencies during a resting EEG recording. Findings revealed elevated levels of delta power among elderly individuals reporting high levels of cumulative life stress. These differed significantly from young high and low stress individuals and old adults with low levels of stress. Increases of delta activity have been linked to the emergence of conditions such as Alzheimer's Disease and Mild Cognitive Impairment. Thus, a potential interpretation of our findings associates large amounts of cumulative stress with an increased risk of developing age-related cognitive pathologies in later life.

This study evaluates serum CD26 (dipeptidyl peptidase IV, DPPIV) enzyme activity and serum levels of soluble CD30 as markers of T1 and T2 cytokine environments in HIV patients who achieved immune reconstitution after highly active antiretroviral therapy (HAART). Patients who had experienced inflammatory disease associated with pre-existent opportunistic infections after HAART (immune restoration diseases, IRD) were considered separately. Serum sCD30 levels and CD26 (DPPIV) enzyme activity were compared with IFN-γ production by PBMC cultured with cytomegalovirus (CMV) antigen in controls and patient groups. High sCD30 levels were associated with low IFN-γ production after antigenic stimulation in control subjects and, to a lesser extent, in immune reconstituted HIV patients. There was no association between serum CD26 (DPPIV) enzyme activity and IFN-γ production or sCD30 levels. Serum sCD30 levels and CD26 (DPPIV) enzyme activity were significantly increased in immune reconstituted patients with high HIV viral loads. Patients who had experienced CMV retinitis as an IRD had significantly higher sCD30 levels than all other patient groups. Hence, high sCD30 levels may be a marker of a T2 cytokine environment in HIV patients with immune reconstitution and are associated with higher HIV viral loads and a history of CMV associated IRD.

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.

Disability is understood by the World Health Organization (WHO) as the outcome of the interaction between a health condition and personal and environmental factors. Comprehensive data about environmental factors is therefore essential to understand and influence disability. We aimed to identify which environmental factors have the highest impact on the performance of people with mild, moderate and severe difficulties in capacity, who are at risk of experiencing disability to different extents, using data from a pilot study of the WHO Model Disability Survey in Cambodia and random forest regression. Hindering or facilitating aspects of places to socialize in community activities, transportation and natural environment as well as use and need of personal assistance and use of medication on a regular basis were the most important environmental factors across groups. Hindering or facilitating aspects of the general environment were the most relevant in persons experiencing mild levels of difficulties in capacity, while social support, attitudes of others and use of medication on a regular basis were highly relevant for the performance of persons experiencing moderate to higher levels of difficulties in capacity. Additionally, we corroborate the high importance of the use and need of assistive devices for people with severe difficulties in capacity.

Through a cross-sectional survey and integrated sound level meter, this research examined noise exposure and auditory- and nonauditory-related problems experienced by students of a dentistry college located in the United Arab Emirates (UAE). A structured interview questionnaire was used to examine hearing-related problems, noise annoyance, and awareness of 114 students toward noise. The results showed that maximum noise levels were between 65 and 79 dB(A) with peak levels (high and low frequencies) ranging between 89 and 93 dB(A). Around 80% of the students experienced a certain degree of noise annoyance; 54% reported one of the hearing-related problems; and about 10% claimed to have hearing loss to a certain extent. It is recommended that sound-absorbent materials be used during the construction of dental clinics and laboratories to reduce the noise levels.

The aims of this study were to examine indicators of socioeconomic deprivation among secondary school students and to determine associations between household poverty, neighbourhood deprivation and health indicators. Data were from a nationally representative sample of 8500 secondary school students in New Zealand who participated in a health survey in 2012. Latent class analyses were used to group students by household poverty based on nine indicators of household socioeconomic deprivation: no car; no phone; no computer; their parent/s worry about not having enough money for food; more than two people sharing a bedroom; no holidays with their families; moving home more than twice that year; garages or living rooms used as bedrooms; and, no parent at home with employment. Multilevel generalized linear models were used to estimate the cross-level interaction between household poverty and neighbourhood deprivation with depressive symptoms, cigarette smoking and overweight/ obesity. Three groups of students were identified: 80 % of students had low levels of household poverty across all indicators; 15 % experienced moderate poverty; and 5 % experienced high levels of poverty. Depressive symptoms and cigarette smoking were 2-3 times higher in the poverty groups compared to student's not experiencing poverty. There were also higher rates of overweight/ obesity among students in the poverty groups compared to students not experiencing poverty, but once covariates were accounted for the relationship was less clear. Of note, students experiencing poverty and living in affluent neighbourhoods reported higher levels of depressive symptoms and higher rates of cigarette smoking than students experiencing poverty and living in low socioeconomic neighbourhoods. This cross-level interaction was not seen for overweight/ obesity. Measures of household socioeconomic deprivation among young people should not be combined with neighbourhood measures of socioeconomic deprivation due to non-linear relationships with health and behaviour indicators. Policies are needed that address household poverty alongside efforts to reduce socioeconomic inequalities in neighbourhoods.

Using a genetically informed design, this study examined the additive and interactive effects of genetic risk, personal peer victimization experiences, and peer victimization experienced by others on children's aggression and depression symptoms. Of major interest was whether these effects varied depending on whether or not the victimized others were children's close friends. The sample comprised 197 monozygotic and same-sex dizygotic twin pairs reared together (95 female pairs) assessed in Grade 4. Each twin's victimization experiences and victimization experienced by his or her friends and other classmates were measured using individuals' reports about their own levels of peer victimization. Aggression was assessed using peer nominations, and depression was measured using self-reports. Indicative of a possible social-learning mechanism or the emotional contagion of anger, multilevel regressions showed that personal victimization experiences were related to especially high levels of aggression when close friends where also highly victimized, albeit only in boys. Moreover, in line with social comparison theory, the effect of frequent personal victimization experiences on depressive feelings was much weaker when close friends were also highly victimized than when close friends were not or were only rarely victimized. Finally, a high level of peer victimization experienced by other classmates was related to a lower level of aggression in girls and boys, possibly because of a heightened sense of threat in classrooms where many suffer attacks from bullies. All of these results were independent of children's genetic risk for aggression or depression. Theoretical and practical implications are discussed. (c) 2013 APA, all rights reserved.

The relationship of demographic factors and negative life events to the mental health of mainland Chinese school students has not been fully explored. Assess the prevalence of different types of life stressors among secondary school students and identify the demographic characteristics and types of life events that are most closely associated with perceived psychological difficulties in these students. This cross-sectional study administered two self-completion questionnaires to a stratified random cluster sample of 1818 students from four secondary schools in two districts of Shanghai: the Strengths and Difficulties Questionnaire (SDQ) and an abbreviated version of the Adolescent Self-rating Life Events Checklist (ASLEC) that assesses 11 negative life events. Academic stress (74%), criticism from others (66%), family conflict (29%) and peer bullying & discrimination or interpersonal conflict (26%) were the most frequently reported negative life events, but their prevalence varied significantly by gender, type of school and urban versus rural residence. Similarly the level of reported psychological stress associated with life events, the total perceived psychological difficulty, and the level of pro-social behavior in the students varied significantly between different groups of students. Multivariate linear regression analysis identified the following independent predictors of high perceived psychological difficulty in the prior 6 months (in order of importance): high total stress score from negative life events in the prior year, experiencing peer bullying & discrimination or interpersonal conflict, not experiencing the death of a family member, male gender, attending a school in a rural district, and not suffering from a major disease or physical impairment. The independent predictors of a high level of pro-social behavior were high total stress score from negative life events, attending an urban school, female gender, attending a regular-tier school (vs. a high-tier school), experiencing peer bullying & discrimination or interpersonal conflict, not experiencing the death of a family member, and attending a middle school (vs. a high school). Negative life events are one of many factors associated with perceived stress and level of pro-social behavior in secondary school students. Prospective studies are needed to clarify the causal pathways that connect stress with negative life events in students and to develop and test cohort-specific interventions aimed at decreasing stress and increasing pro-social behaviors.

The present study examines the within-person relationship of daily stressors and tiredness and whether this depends on daily negative affect and individual differences in chronic stress. One hundred sixteen older adult participants were recruited via Amazon's Mechanical Turk for a 9-day daily diary study. Daily tiredness, daily stressors, and negative affect were measured each day, and chronic stress was measured at baseline. Daily stressors, daily negative affect, and chronic stress interacted to predict daily tiredness. People with high chronic stress who experienced an increase in daily negative affect were the most reactive to daily stressors in terms of experiencing an increase in daily tiredness. We also found that people with low levels of chronic stress were the most reactive to daily stressors when they experienced low levels of daily negative affect. Our results highlight the need for individualized and contextualized approaches to combating daily tiredness in older adults.

The Integrated Task Modeling Environment (ITME) is a user-friendly software tool that has been developed to automatically recode low-level data into an empirical record of meaningful task performance. The present research investigated and validated the performance of the ITME software package by conducting complex simulation missions and comparing the task analyses produced by ITME with taskanalyses produced by experienced video analysts. A very high interrater reliability (> or = .94) existed between experienced video analysts and the ITME for the task analyses produced for each mission. The mean session time:analysis time ratio was 1:24 using video analysis techniques and 1:5 using the ITME. It was concluded that the ITME produced task analyses that were as reliable as those produced by experienced video analysts, and significantly reduced the time cost associated with these analyses.

The effects of HMO ownership on hospital costs and revenues: is there a difference between for-profit and nonprofit plans?

2004-01-01

We conducted multivariate analyses to examine whether high health maintenance organization (HMO) penetration and large share of for-profit health plans in a market reduced hospital cost and revenue growth rates between 1989 and 1998. We found that hospitals in high HMO areas experienced revenue and cost growth rates that were 21 and 18 percentage points, respectively, below hospitals in low HMO areas. We also found that, conditional on overall HMO penetration level, hospitals in areas with high for-profit HMO penetration experienced revenue and cost growth rates that were 10 percentage points below hospitals in areas with low for-profit penetration areas; the difference was especially evident within high HMO penetration areas.

Evaluating transformational leadership skills of hospice executives.

2006-01-01

Health care is a rapidly changing environment requiring a high level of leadership skills by executive level personnel. The hospice industry is experiencing the same rapid changes; however, the changes have been experienced over the brief span of 25 years. Highly skilled hospice executives are a necessity for the growth and long-term survival of hospice care. This descriptive study was conducted to evaluate the leadership skills of hospice executives. The study population consisted of hospice executives who were members of the state hospice organization in Ohio and/or licensed by the state (88 hospice providers). Three questionnaires were utilized for collecting data. These questionnaires collected data on transformational leadership skills of participants, participants' personal demographics, and their employer's organizational demographics. Forty-seven hospice executives responded (53%). Key findings reported were high levels of transformational leadership skills (mean, 3.39), increased use of laissez-faire skills with years of hospice experience (P = .57), and positive reward being a frequent leadership technique utilized (mean, 3.29). In addition, this was the first study of leadership skills of hospice executives and the first formal collection of personal demographic data about hospice executives.

Ron, Pnina; Shamai, Michal

2014-04-01

The main goal of this study was to explore the connections between the exposure of nurses in Israel to national terror and the levels of distress experienced due to ongoing terror attacks. The data were collected from 214 nurses from various parts of Israel who work in three types of heath services (mainly hospital departments) and provide help to victims of terror. The nurses reported very high levels of burnout, high levels of stress and medium-to high levels of intrusive memories. Levels of exposure were associated with burnout, intrusive memories and level of stress. More professional attention should be given to hospital nurses who provide care for trauma patients.

Emotional reactions to crime across cultures.

Matsumoto, David; Hwang, Hyisung C

2015-10-01

Information about the emotions experienced by observers when they witness crimes would have important theoretical and practical implications, but to date no study has broadly assessed such emotional reactions. This study addressed this gap in the literature. Observers in seven countries viewed seven videos portraying actual crimes and rated their emotional reactions to each using 14 emotion scales. Observers reported significantly high levels of negative emotions including anger, contempt, disgust, fear and sadness-related emotions, and anger, contempt and disgust were the most salient emotions experienced by viewers across all countries. Witnesses also reported significantly high levels of positive emotions as well (compared to not feeling the emotion at all), which was unexpected. Country moderated the emotion ratings; post-hoc analyses indicated that masculine-oriented cultures reported less nervousness, surprise, excitement, fear and embarrassment than feminine cultures. © 2014 International Union of Psychological Science.

Background level of risk and the survival of predator-naive prey: can neophobia compensate for predator naivety in juvenile coral reef fishes?

PubMed

Ferrari, Maud C O; McCormick, Mark I; Meekan, Mark G; Chivers, Douglas P

2015-01-22

Neophobia--the generalized fear response to novel stimuli--provides the first potential strategy that predator-naive prey may use to survive initial predator encounters. This phenotype appears to be highly plastic and present in individuals experiencing high-risk environments, but rarer in those experiencing low-risk environments. Despite the appeal of this strategy as a 'solution' for prey naivety, we lack evidence that this strategy provides any fitness benefit to prey. Here, we compare the relative effect of environmental risk (high versus low) and predator-recognition training (predator-naive versus predator-experienced individuals) on the survival of juvenile fish in the wild. We found that juveniles raised in high-risk conditions survived better than those raised in low-risk conditions, providing the first empirical evidence that environmental risk, in the absence of any predator-specific information, affects the way naive prey survive in a novel environment. Both risk level and experience affected survival; however, the two factors did not interact, indicating that the information provided by both factors did not interfere or enhance each other. From a mechanistic viewpoint, this indicates that the combination of the two factors may increase the intensity, and hence efficacy, of prey evasion strategies, or that both factors provide qualitatively separate benefits that would result in an additive survival success.

Helicopter pilot scan techniques during low-altitude high-speed flight.

PubMed

Kirby, Christopher E; Kennedy, Quinn; Yang, Ji Hyun

2014-07-01

This study examined pilots' visual scan patterns during a simulated high-speed, low-level flight and how their scan rates related to flight performance. As helicopters become faster and more agile, pilots are expected to navigate at low altitudes while traveling at high speeds. A pilot's ability to interpret information from a combination of visual sources determines not only mission success, but also aircraft and crew survival. In a fixed-base helicopter simulator modeled after the U.S. Navy's MH-60S, 17 active-duty Navy helicopter pilots with varying total flight times flew and navigated through a simulated southern Californian desert course. Pilots' scan rate and fixation locations were monitored using an eye-tracking system while they flew through the course. Flight parameters, including altitude, were recorded using the simulator's recording system. Experienced pilots with more than 1000 total flight hours better maintained a constant altitude (mean altitude deviation = 48.52 ft, SD = 31.78) than less experienced pilots (mean altitude deviation = 73.03 ft, SD = 10.61) and differed in some aspects of their visual scans. They spent more time looking at the instrument display and less time looking out the window (OTW) than less experienced pilots. Looking OTW was associated with less consistency in maintaining altitude. Results may aid training effectiveness specific to helicopter aviation, particularly in high-speed low-level flight conditions.

The fatigue that is observed in patients who are undergoing dialysis is usually associated with an impaired quality of life. The present cross-sectional study was conducted from January to April 2009 in three hemodialysis units in Kuala Lumpur, Malaysia. In this study, the Multidimensional Fatigue Inventory and Depression Anxiety and Stress Score 21 were used to determine the level of fatigue, depression, anxiety, and stress of patients who were undergoing dialysis. The data were obtained from a calculated sample of 116 and a total of 103 respondents participated in the study. A total of 56 (54.4%) and 47 (45.6%) respondents experienced a high level and a low level of fatigue, respectively. There was a significant relationship between the duration of treatment and the level of fatigue. The respondents who had been receiving treatment for > 2 years experienced more fatigue, compared to the respondents who had been undergoing hemodialysis for > 2 years. There was a significant difference in relation to the age of the participants regarding the level of fatigue. No significant relationship between the sex of the participants, anemia, depression, anxiety, stress, and the level of fatigue was observed. Special attention needs to be paid to both the younger and older adults who are receiving treatment. In addition, proper planning is needed for the patients regarding their daily activities in order to reduce fatigue. Nurses who work in hemodialysis units are recommended to provide exercise classes or group therapy in order to boost the energy levels among patients who are undergoing dialysis. Health professionals should provide appropriate treatment for patients who are experiencing fatigue in order to prevent any other complications that could arise. © 2011 Blackwell Publishing Asia Pty Ltd.

[High prevalence of work-family conflict among female physicians: lack of social support as a potential antecedent].

PubMed

Adám, Szilvia

2009-12-13

According to stress theory, social support from work and non-work-related sources may influence the level of perceived work-family conflict. Despite the high prevalence of work-family conflict as a source of distress among female physicians, no information is available on the associations between work-family conflict and social support in a traditional, family-centric cultural setting, where female role expectations are demanding. The author hypothesized that high prevalence of work-family conflict could be attributed to the lack of social support among female physicians. To investigate the prevalence and psychosocial characteristics of social support and its relations to work-family conflict among female physicians. Quantitative and qualitative study using questionnaires ( n = 420) and in-depth interviews ( n = 123) among female and male physicians. Female physicians reported significantly higher mean level and prevalence of work-family conflict compared to men. The predominant form of work-family was work-to-family conflict among physicians; however, significantly more female physicians experienced family-to-work conflict and strain-based work-family conflict compared to men (39% vs. 18% and 68% vs. 20%, respectively). Significantly more male physicians experienced time-based work-family conflict compared to women. Content analyses of interview data revealed that provision of support to physicians manifested itself in parental support in career selection, spousal support with household duties, peer support with enabling access to professional role models-mentors, peer support to ensure gender equity, and organizational support with family-centric policies. Female physicians reported significantly less parental, spousal, and peer support compared to men. Female physicians lacking parental, peer, or organizational support experienced significantly higher level of work-family conflict compared to appropriate control. In regression analyses, high job demands, job strain, high workload and number of children, younger age, and lack of support in the workplace predicted work-family conflict best (adjusted R 2 0.59). Lack of social - particularly parental, peer, and organizational - support may play an important role in the pathogenesis of work-family conflict experienced by female physicians.

To identify contextual and interpersonal factors that distinguish families in which the intergenerational transmission of maltreatment is maintained from families in which the cycle is broken. The sample was composed of 1,116 families in the United Kingdom who participated in the Environmental Risk (E-Risk) Longitudinal Twin Study. We assessed mother's childhood history of maltreatment retrospectively with a validated and reliable interview. Prospective reports of children's physical maltreatment were collected repeatedly up to 12 years. We compared families in which mothers but not children had experienced maltreatment with families in which both mothers and children had experienced maltreatment, and with families without maltreatment, on a range of contextual and interpersonal factors known to affect child development. In multivariate analyses, supportive and trusting relationships with intimate partners, high levels of maternal warmth toward children, and low levels of partner violence between adults distinguished families in which mothers but not children experienced maltreatment from families in which mothers and children experienced maltreatment. Families in which only mothers experienced maltreatment were largely similar to families in which neither generation experienced maltreatment, except that mothers belonging to the former group were more likely to have a lifetime history of depression and low levels of social support. Safe, stable, nurturing relationships between intimate partners and between mothers and children are associated with breaking the cycle of abuse in families. Additional research is needed to determine whether these factors have a causal role in preventing the transmission of maltreatment from one generation to the next.

2008-12-01

The positive and negative psychological impact of secondary exposure to politically motivated violence was examined among body handlers and hospital rehabilitation workers, 2 groups that differed in their proximity and immediacy to violent events. Survivors of politically motivated violence served as a comparison group. Body handlers experienced high levels of positive psychological impact and traumatic stress symptoms. Levels of positive psychological impact among on-scene body handlers were higher than those experienced by rehabilitation workers. Traumatic stress symptoms predicted positive psychological impact among body handlers. These findings indicate that proximity to stressors is associated with higher levels of positive and negative psychological impact. Physical proximity is a major contributory factor to both positive and negative psychological effects of secondary exposure to trauma.

2018-05-01

This study compared three groups of various age and health status (total N = 732) with respect to their identity status, stress level, and parental behavior. As expected, patients were characterized by delayed identity development, particularly ruminative exploration. Further, patients experienced high identity stress and described high levels of anxious paternal rearing and intrusive maternal psychological control. The patients‘ levels of both internalizing and externalizing symptomatology were high, and the impact of externalizing symptoms on identity arrest was strong. Identity status was delayed, albeit age adequate in both groups of healthy youths, with comparably high levels of anxious parental monitoring. Compared to adolescents, young adults were particularly active in their identity development, showing a high level of identity stress but no increase in psychopathology.

Family Economic Stress, Quality of Paternal Relationship, and Depressive Symptoms among African American Adolescent Fathers

2015-01-01

This study examined the association between perceived family economic stress, quality of father-son relationships, and depressive symptoms among African American adolescent fathers. Data were collected during pregnancy from 65 African American adolescents who were first-time fathers, ages 14-19. Results from multiple regression analyses indicated that higher paternal relationship satisfaction was associated with fewer depressive symptoms among adolescent fathers. Additionally, depressive symptoms were higher among adolescent fathers who reported experiencing higher levels of conflict with their fathers. Further, paternal conflict moderated the effect of perceived family economic stress on depressive symptoms. That is, among adolescent fathers experiencing low levels of conflict with their fathers, high perceived family economic stress was associated with more depressive symptoms. Study findings suggest that the risk for depressive symptoms is highest among adolescent fathers experiencing low family economic stress and highly conflictual relations with their fathers. These results highlight the complexities of paternal relationships and perceived economic stressors on depressive symptoms during pregnancy for African American adolescent fathers. The importance of expanding research on influential familial relationships and economic stressors on adolescent African American fathers is discussed. PMID:26617454

2016-01-01

The current study investigated the previously unexamined relationship between politics perceptions and employee enactment behavior. Consistent with previous job stress and sense-making research, we hypothesized that individuals reporting low levels of enactment behaviors would be more adversely affected by politics perceptions than those who engaged in high levels of enactment behavior. Results across two samples provided strong support for the hypothesized relationships. Specifically, employees who reported low levels of enactment behavior experienced less satisfaction, less person-environment fit, and reported lower levels of effort when faced with highly political environments. Conversely, levels of satisfaction and person-environment fit perceptions of individuals reporting high levels of enactment behaviors were largely unaffected by highly political contexts. Implications of these findings, strengths and limitations, and avenues for future research are provided.

Religion plays a prominent role in Latino culture and could be influential during difficult life transitions, such as those experienced during the immigration process. This study examines relations between religious coping, acculturative stress, and alcohol use in a sample of 415 recent Latino immigrants. Higher levels of acculturative stress were associated more positive and negative religious coping. Positive religious coping was related to lower alcohol use. Negative religious coping moderated the relationship between acculturative stress and alcohol use. Participants who used more negative religious coping had higher rates of alcohol use when experiencing high levels acculturative stress. Implications for culturally tailored prevention/interventions are discussed.

When alcohol is only part of the problem: An event-level analysis of negative consequences related to alcohol and other substance use.

While alcohol remains the drug of choice for most college students, national data show that 40% of college students also use other substances (e.g., marijuana, cocaine, etc.). Longitudinal studies indicate that students who report use of both alcohol and other substances experience more consequences (e.g., blackout, arrests). The current study expands upon this research by using a multilevel approach to examine average and event-level alcohol combined with other substance use (ALC+) and its role on consequences experienced. In addition, the research examined which substance combined with alcohol posed the most risk. A total of 461 students reported on alcohol use, substance use, and consequences experienced (e.g., Young Adult Alcohol Consequences Questionnaire [YAACQ]) on 12 weekend nights (Thursday, Friday, Saturday) across 4 weekends in an academic year. Multilevel model analyses revealed a positive association between both average and event-level ALC+ use and the number of consequences experienced. A significant cross-level interaction was also revealed indicating students who typically combine alcohol and other substances experienced more consequences on occasions when they use more substances relative to students who typically use alcohol only. Finally, alcohol plus nicotine, or marijuana, or attention-deficit/hyperactivity disorder (ADHD) medications, or cocaine were all significantly positively related to increased consequences. These findings provide consistent evidence that ALC+ use is a highly prevalent behavior among college students that increases risk of problematic consequences.

Psychological symptoms and marital satisfaction in spouses of Operation Iraqi Freedom veterans: relationships with spouses' perceptions of veterans' experiences and symptoms.

PubMed

Renshaw, Keith D; Rodrigues, Camila S; Jones, David H

2008-08-01

Much research has shown that spouses of combat veterans with posttraumatic stress disorder (PTSD) have higher rates of psychological and marital distress than do spouses of veterans without PTSD; however, very few studies have examined potential mechanisms of this increased vulnerability. The current study examined spouses of National Guard soldiers recently returned from deployments in Iraq. In addition to documenting elevated levels of psychological symptoms in these spouses, the authors found that spouses experienced greater symptom severity when they perceived high levels of symptoms in soldiers but the soldiers endorsed low levels of symptoms. Furthermore, spouses' marital satisfaction was negatively linked to soldiers' self-reported symptom severity only when spouses perceived that soldiers had experienced low levels of combat activity while deployed. When spouses perceived high levels of such activity, soldiers' self-reported symptoms had no relationship with spouses' marital satisfaction. These findings highlight the importance of interpersonal perceptions in intimate relationships and are consistent with the notion that uncontrollable attributions for a relative's mental health problems may provide a buffer against relationship distress.

The reasons for these burdens and degree to which they are experienced are explored in this paper. Our study adds to international research regarding the burden experienced by volunteers. This project is the first to assess how community health volunteers in Taiwan experience burden. Methods The 20 item Burden on Community Health Volunteer (BCHV) instrument, specifically designed for this project, was administered to 435 volunteers attached to Community Health Promotion Development Centres in northern Taiwan. Results The overall burden experienced by volunteers is relatively low. However, a multivariate adjusted regression analysis revealed significant differences in volunteer burden depending on the number of people each volunteer served on average per week, as well as the volunteer’s marital status and their perceptions about personal health. Volunteers who served many people and who perceived their own health as poor experienced a higher level of burden. Those who were a widow or a widower felt less burdened than others. Conclusions The results of the study identify areas where burden is high and where strategies can be developed to reduce the level of burden experienced by community health volunteers in Taiwan. Community health volunteers in Taiwan complement the role of nurses and other health care providers so their retention is important to ongoing service delivery. PMID:23687966

To explore satisfaction and burnout of nurses working in neurology wards in Shanghai, China. A descriptive cross-sectional questionnaire survey. Three hundred and eighty-seven nurses from 23 neurology wards in 21 tertiary general hospitals were recruited using cluster sampling. The valid response rate was 94.83%. Nurse satisfaction with the salary/wages, the job and the nurse staffing level were 21.79%, 37.33%, and 40.87%. A high nurse burnout rate was found as: emotional exhaustion (EE) ≥ 27 (89.92%); depersonalization (DP) ≥ 10 (92.64%); and reduced personal accomplishment (PA)≤ 33 (79.29%). Most nurses in the neurology wards were dissatisfied and had high levels of burnout. Experienced, intermediate and senior nurses were at the highest risk for job turnover. Nurse administrators should take effective measures to increase nurse satisfaction and decrease burnout to retain experienced nurses and keep the stability of nursing workforce. © 2014 Association of Rehabilitation Nurses.

Geometry is one part of the mathematics that must be learned in school and it has important effects on the development of creative thinking skills of learners, but in fact, there are some difficulties experienced by the students. This research focuses on analysis difficulty in resolving rectangular conceptual problems among junior high school students in every creative thinking skills level. This research used a descriptive method aimed to identify the difficulties and cause of the difficulties experienced by five students. The difficulties are associated with rectangular shapes and related problems. Data collection was done based on students' work through test, interview, and observations. The result revealed that student' difficulties in understanding the rectangular concept can be found at every creative thinking skills level. The difficulties are identifying the objects rectangular in the daily life except for a rectangle and square, analyzing the properties of rectangular shapes, and seeing the interrelationships between figures.

Perceptions of friendship among youth with distressed friends.

This cross-sectional study examined the relationship between a friend's level of internalizing distress and the focal child's perceptions of friendship amongst 5th, 8th, and 11th grade youth. Participants completed the Youth Self-Report to assess internalizing distress and measures assessing perceptions of friendship quality, social support, and self-disclosure within reciprocal, same-sex friendship dyads. Results indicated that youth with friends experiencing low levels of internalizing distress reported poorer friendship quality and decreased levels of social support and self-disclosure within the friendship compared to youth with friends experiencing average or high internalizing distress. In a second set of analyses controlling for the focal child's own internalizing symptoms, gender, and age, friend's level of internalizing distress remained a significant, unique predictor of target participants' self-disclosure about their own problems within the friendship. The findings suggest that a mild degree of internalizing distress may enhance, rather than harm, friendships amongst youth.

As participation in women's soccer continues to grow and the longevity of female athletes' careers continues to increase, prevention and care for mTBI in women's soccer has become a major concern for female athletes since the long-term risks associated with a history of mTBI are well documented. Among women's sports, soccer exhibits among the highest concussion rates, on par with those of men's football at the collegiate level. Head impact monitoring technology has revealed that "concussive hits" occurring directly before symptomatic injury are not predictive of mTBI, suggesting that the cumulative effect of repetitive head impacts experienced by collision sport athletes should be assessed. Neuroimaging biomarkers have proven to be valuable in detecting brain changes that occur before neurocognitive symptoms in collision sport athletes. Quantifying the relationship between changes in these biomarkers and head impacts experienced by female soccer athletes may prove valuable to developing preventative measures for mTBI. This study paired functional magnetic resonance imaging with head impact monitoring to track cerebrovascular reactivity changes throughout a season and to test whether the observed changes could be attributed to mechanical loading experienced by female athletes participating in high school soccer. Marked cerebrovascular reactivity changes were observed in female soccer athletes, relative both to non-collision sport control measures and pre-season measures and were localized to fronto-temporal aspects of the brain. These changes persisted 4-5 months after the season ended and recovered by 8 months after the season. Segregation of the total soccer cohort into cumulative loading groups revealed that population-level changes were driven by athletes experiencing high cumulative loads, although athletes experiencing lower cumulative loads still contributed to group changes. The results of this study imply a non-linear relationship between cumulative loading and cerebrovascular changes with a threshold, above which the risk, of injury likely increases significantly.

The purpose of this study was to identify student clusters with homogenous profiles in perceptions of task- and ego-involving, autonomy, and social relatedness supporting motivational climate in school physical education. Additionally, we investigated whether different motivational climate groups differed in their enjoyment in PE. Participants of the study were 2 594 girls and 1 803 boys, aged 14-15 years. Students responded to questionnaires assessing their perception of motivational climate and enjoyment in physical education. Latent profile analyses produced a five-cluster solution labeled 1) 'low autonomy, relatedness, task, and moderate ego climate' group', 2) 'low autonomy, relatedness, and high task and ego climate, 3) 'moderate autonomy, relatedness, task and ego climate' group 4) 'high autonomy, relatedness, task, and moderate ego climate' group, and 5) 'high relatedness and task but moderate autonomy and ego climate' group. Analyses of variance showed that students in clusters 4 and 5 perceived the highest level of enjoyment whereas students in cluster 1 experienced the lowest level of enjoyment. The results showed that the students' perceptions of various motivational climates created differential levels of enjoyment in PE classes.

To consider the consequences, within a UK population sample, of consuming a given amount of alcohol weekly in one or two sessions as against spreading it out over several sessions. A new analysis of data from the UK components of the GENACIS survey of adults aged > or =18, was carried out. At low levels of weekly alcohol consumption those subjects whose usual drinking frequency was several times per week ('spreaders'), if anything, reported more alcohol problems than those who consumed alcohol only once or twice per week ('bingers'). As weekly consumption increased above approximately 11 units per week 'bingers' began to experience more problems than 'spreaders'. At the highest levels of consumption 'bingers' reported more positive experiences from drinking than did 'spreaders'. Subjects >54 years showed lower levels of weekly alcohol consumption than other subjects, and relationships between problems, drinking level, and drinking pattern were less in evidence. Females drank less alcohol and experienced fewer alcohol-related problems than did their male counterparts. However, at high-consumption levels, female 'bingers' experienced fewer problems than male 'bingers'. For most but not all the variables studied, both drinking level and drinking pattern are important determinants of problems experienced. Binge drinking for people who drink more than approximately 11 units per week is an obvious target for harm minimization.

[High prevalence of job dissatisfaction among female physicians: work-family conflict as a potential stressor].

Due to the family-centric nature of Hungarian society and to the high proportion of women in the medical profession, more female than male physicians may experience work-family conflict. The authors hypothesized that work-family conflict may reduce job satisfaction among female physicians. However, there is limited information about the prevalence of work-family conflict and job dissatisfaction as well as their associations among female physicians. To explore the prevalence of work-family conflict and its relations to job dissatisfaction among Hungarian physicians. Cross-sectional study with 219 female and 201 male physicians using self-report questionnaires. As hypothesized, female physicians reported significantly higher level of work-family conflict compared to male physicians (3.0 (SD 0.9) vs. 2.6 (SD 0.9); t (df): -3.8 (418); p < 0.001). Furthermore, more female than male physicians experienced work-family conflict often or extremely often [56% vs. 41%, respectively; chi 2 (df) = 9.3 (1); p < 0.01]. Significantly fewer women (55%) than men (66%) reported high levels of job satisfaction [chi 2 (df) = 4.8 (1), p < 0.05]. Similarly, significantly more female physicians (13%) experienced high level of job dissatisfaction compared to men (6%) [chi 2 (df) = 4.7 (1), p < 0.05]. Linear regression analyses showed that work-family conflict predicts job dissatisfaction among female and all physicians (beta = -0.17, 95% CI -0.31 - -0.04 and beta = -0.14, 95% CI -0.22 - -0.04, respectively). These results show that the level and prevalence of work-family conflict experienced by female physicians in Hungary is significantly higher than that among male physicians. Furthermore, these findings suggest that work-family conflict as a stressor may contribute to the development of job dissatisfaction and hence may adversely impact the well-being of female and male physicians and consequently the quality of patient care.

While evidence indicates that experienced racial discrimination is associated with increased depressive symptoms for African Americans, there is little research investigating predictors of experienced racial discrimination. This paper examines neighborhood racial composition and sociodemographic factors as antecedents to experienced racial discrimination and resultant levels of depressive symptoms among African American adults. The sample included 505 socioeconomically-diverse African American adults from Baltimore, MD. Study data were obtained via self-report and geocoding of participant addresses based on 2010 census data. Study hypotheses were tested using multiple pathways within a longitudinal Structural Equation Model. Experienced racial discrimination was positively associated with age and sex such that older individuals and males experienced increased levels of racial discrimination. In addition, the percentage of White individuals residing in a neighborhood was positively associated with levels of experienced racial discrimination for African American neighborhood residents. Experienced racial discrimination was positively associated with later depressive symptoms. Neighborhood-level contextual factors such as neighborhood racial composition and individual differences in sociodemographic characteristics appear to play an important role in the experience of racial discrimination and the etiology of depression in African American adults.

University students are prone to stressors due to the transitional nature of university life. High levels of stress are believed to affect students' health as well as their academic performance. The aims of this study were to identify stressors and reactions to stressors among university students, and to examine the correlations between student stressors and study variables. A correlational descriptive design was used. Student-life Stress Inventory (SSI) was used to measure the stressors and reactions to stressors. Stratified random sampling was employed to recruit participants. The final sample consisted of 877 participants (students). s indicated that the highest group of stressors experienced by students were 'self-imposed' stressors followed by 'pressures'. Cognitive responses were found to be the highest responses to stressors experienced by students. Negative correlations were found with student's perception of health, and father's and mother's level of education. This study revealed that stressors among university students come from 'self-imposed' stressors and 'pressures'. Stress management, assertiveness skills, time management and counselling sessions will be effective in reducing stress experienced by students.

The impacts of precursor reduction and meteorology on ground-level ozone in the Greater Toronto Area

Tropospheric ozone (O3) is a major component of photochemical smog and is a known human health hazard, as well as a damaging factor for vegetation. Its precursor compounds, nitrogen oxides (NOx) and volatile organic compounds (VOCs), have a variety of anthropogenic and biogenic sources and exhibit non-linear effects on ozone production. As an update to previous studies on ground-level ozone in the Greater Toronto Area (GTA), we present an analysis of NO2, VOC and O3 data from federal and provincial governmental monitoring sites in the GTA from 2000 to 2012. We show that, over the study period, summertime 24 h VOC reactivity and NO2 midday (11:00-15:00) concentrations at all sites decreased significantly; since 2000, all sites experienced a decrease in NO2 of 28-62% and in measured VOC reactivity of at least 53-71%. Comparing 2002-2003 to 2011-2012, the summed reactivity of OH towards NO2 and a suite of measured VOCs decreased from 8.6 to 4.6 s-1. Ratios of reactive VOC pairs indicate that the effective OH concentration experienced by primary pollutants in the GTA has increased significantly over the study period. Despite the continuous decrease in precursor levels, ozone concentrations are not following the same pattern at all stations; it was found that the Canada-wide Standard for ozone continues to be exceeded at all monitoring stations. Additionally, while the years 2008-2011 had consistently lower ozone levels than previous years, 2012 experienced one of the highest recorded summertime ozone concentrations and a large number of smog episodes. We demonstrate that these high ozone observations in 2012 may be a result of the number of days with high solar radiation, the number of stagnant periods and the transport of high ozone levels from upwind regions.

Objective To examine patterns of conflict-related violence and intimate partner violence (IPV) and their associations with emotional distress among Congolese refugee women living in Rwanda. Design Cross-sectional study. Setting Two Congolese refugee camps in Rwanda. Participants 548 ever-married Congolese refugee women of reproductive age (15–49 years) residing in Rwanda. Primary outcome measure Our primary outcome was emotional distress as measured using the Self-Report Questionnaire-20 (SRQ-20). For analysis, we considered participants with scores greater than 10 to be experiencing emotional distress and participants with scores of 10 or less not to be experiencing emotional distress. Results Almost half of women (49%) reported experiencing physical, emotional or sexual violence during the conflict, and less than 10% of women reported experiencing of any type of violence after fleeing the conflict. Lifetime IPV was reported by approximately 22% of women. Latent class analysis derived four distinct classes of violence experiences, including the Low All Violence class, the High Violence During Conflict class, the High IPV class and the High Violence During and After Conflict class. In multivariate regression models, latent class was strongly associated with emotional distress. Compared with women in the Low All Violence class, women in the High Violence During and After Conflict class and women in the High Violence During Conflict had 2.7 times (95% CI 1.11 to 6.74) and 2.3 times (95% CI 1.30 to 4.07) the odds of experiencing emotional distress in the past 4 weeks, respectively. Furthermore, women in the High IPV class had a 4.7 times (95% CI 2.53 to 8.59) greater odds of experiencing emotional distress compared with women in the Low All Violence class. Conclusions Experiences of IPV do not consistently correlate with experiences of conflict-related violence, and women who experience high levels of IPV may have the greatest likelihood for poor mental health in conflict-affected settings.

Objective Metastatic breast cancer can be challenging for couples given the significant pain and distress caused by the disease and its treatment. While the use of catastrophizing (e.g., ruminating, exaggerating) as a pain coping strategy has been associated with depression in breast cancer patients, little is known about the effects of pain intensity on this association. Moreover, even though social relationships are a fundamental resource for couples coping with cancer, no studies have examined whether the quality of the spousal relationship affects the association between catastrophizing and depression. This study prospectively examined these associations. Methods Couples (N=191) completed surveys at the start of treatment for metastatic breast cancer (baseline), and 3 and 6 months later. Results Multilevel models using the couple as the unit of analysis showed patients and partners (i.e., spouses or significant others) who had high levels (+1SD) of dyadic adjustment (DAS7) experienced fewer depressive symptoms than those who had low levels (−1SD) of dyadic adjustment (ps<.01). Moreover, at low levels of dyadic adjustment, when patients engaged in high levels of catastrophizing and had high levels of pain, both patients and their partners reported significantly (p=.002) higher levels of depression than when patients engaged in high levels of catastrophizing but had low levels of pain. Discussion Findings showed that catastrophizing and pain exacerbate depression in couples experiencing marital distress. Programs that seek to alleviate pain and depressive symptoms in metastatic breast cancer may benefit from targeting both members of the couple, screening for marital distress, and teaching more adaptive pain coping strategies.

2009-01-01

This study takes a developmental psychopathological approach to examine mechanisms through which baseline levels of positive emotionality (PE) and negative emotionality (NE) prospectively predict increases in anhedonic depressive symptoms in a community sample of 350 adolescents (6th–10th graders). Dependent stressors mediated the relationship between baseline levels of NE and anhedonic depressive symptoms after controlling for initial symptoms. Supportive relationships mediated the relationship between baseline levels of PE and anhedonic depressive symptoms, after controlling for baseline symptoms. In addition, NE × PE interacted to predict later anhedonic depressive symptoms, such that adolescents with low levels of PE and high levels of NE experienced the greatest increase in anhedonic depressive symptoms. Last, supportive relationships interacted with baseline PE to predict prospective changes in anhedonic depressive symptoms, such that adolescents with low PE and low supportive relationships experienced the greatest increase in anhedonic depressive symptoms. Results are discussed in terms of current theoretical models of the link between temperament and depression. PMID:19184402

Parental Effect of Long Acclimatization on Thermal Tolerance of Juvenile Sea Cucumber Apostichopus japonicus

To evaluate the thermal resistance of marine invertebrates to elevated temperatures under scenarios of future climate change, it is crucial to understand parental effect of long acclimatization on thermal tolerance of offspring. To test whether there is parental effect of long acclimatization, adult sea cucumbers (Apostichopus japonicus) from the same broodstock were transplanted southward and acclimatized at high temperature in field mesocosms. Four groups of juvenile sea cucumbers whose parents experienced different durations of high temperature acclimatization were established. Upper thermal limits, oxygen consumption and levels of heat shock protein mRNA of juveniles was determined to compare thermal tolerance of individuals from different groups. Juvenile sea cucumbers whose parents experienced high temperature could acquire high thermal resistance. With the increase of parental exposure duration to high temperature, offspring became less sensitive to high temperature, as indicated by higher upper thermal limits (LT50), less seasonal variations of oxygen consumption, and stable oxygen consumption rates between chronic and acute thermal stress. The relatively high levels of constitutive expression of heat-shock proteins should contribute to the high thermal tolerance. Together, these results indicated that the existence of a parental effect of long acclimatization would increase thermal tolerance of juveniles and change the thermal sensitivity of sea cucumber to future climate change.

Tinnitus is associated with reduced sound level tolerance in adolescents with normal audiograms and otoacoustic emissions

2016-01-01

Recent neuroscience research suggests that tinnitus may reflect synaptic loss in the cochlea that does not express in the audiogram but leads to neural changes in auditory pathways that reduce sound level tolerance (SLT). Adolescents (N = 170) completed a questionnaire addressing their prior experience with tinnitus, potentially risky listening habits, and sensitivity to ordinary sounds, followed by psychoacoustic measurements in a sound booth. Among all adolescents 54.7% reported by questionnaire that they had previously experienced tinnitus, while 28.8% heard tinnitus in the booth. Psychoacoustic properties of tinnitus measured in the sound booth corresponded with those of chronic adult tinnitus sufferers. Neither hearing thresholds (≤15 dB HL to 16 kHz) nor otoacoustic emissions discriminated between adolescents reporting or not reporting tinnitus in the sound booth, but loudness discomfort levels (a psychoacoustic measure of SLT) did so, averaging 11.3 dB lower in adolescents experiencing tinnitus in the acoustic chamber. Although risky listening habits were near universal, the teenagers experiencing tinnitus and reduced SLT tended to be more protective of their hearing. Tinnitus and reduced SLT could be early indications of a vulnerability to hidden synaptic injury that is prevalent among adolescents and expressed following exposure to high level environmental sounds.

Klein, Hugh

2014-05-01

This research examines the levels of condom use self-efficacy in a population of men who have sex with men who are at great risk for contracting/transmitting HIV. It focuses on the relationship between condom use self-efficacy and risk involvement, and examines the factors associated with greater/lower levels of condom use self-efficacy. The data come from a national sample of men, randomly chosen, who used any of 16 websites specifically to identify other men with whom they could engage in unprotected sex. Data were collected between January 2008 and May 2009 from 332 men, via telephone interviews. Multivariate analyses and structural equation modeling were used to test a conceptual model based on syndemics theory. Overall levels of condom use self-efficacy were fairly high, and self-efficacy was related inversely to involvement in HIV risk practices. Six factors were found to be indicative of levels of condom use self-efficacy: the number of drug problems experienced, sexual role identity as a "bottom," not caring about the HIV serostatus of potential sex partners, experiencing childhood maltreatment, having confidence in HIV-related information provided in other men's online profiles, and level of HIV knowledge. Condom use self-efficacy plays an integral role in HIV risk practices among high-risk men who have sex with men. This is true despite the fact that, overall, condom use self-efficacy levels were fairly high in this population.

Much etiologic research has focused on individual-level risk factors for teen dating violence (TDV); therefore, less is known about school-level and neighborhood-level risk factors. We examined the association between alcohol outlet density around high schools and TDV victimization and the association between markers of physical disorder around schools and TDV victimization among adolescents. Data come from high school students participating in the Maryland Safe and Supportive Schools Initiative. Alcohol outlet density was calculated using walking distance buffers around schools. An observational tool was used to assess indicators of physical disorder on school property (eg, alcohol and drug paraphernalia). Hierarchical linear modeling was used to identify student- and school-level predictors associated with TDV victimization. Overall, 11% of students reported experiencing physical TDV and 11% reported experiencing psychological TDV over the past year. Recent alcohol use was a risk factor for TDV victimization for both sexes, whereas feeling safe at school was protective against TDV victimization for both sexes. Greater alcohol outlet density was associated with decreased TDV victimization for males, however, it was nonsignificant for females. Physical disorder around schools was not associated with TDV victimization for either sex. Although the school-level predictors were not associated with TDV victimization, alcohol use and perceptions of safety at school were significantly associated with TDV victimization. Prevention efforts to address alcohol use may affect TDV victimization. © 2017, American School Health Association.

Amyotrophic lateral sclerosis (ALS) causes distress in caregivers. The present study aims to examine the association between coping strategies and psychological distress in caregivers of ALS patients. Coping strategies were assessed in 96 ALS informal caregivers by means of the Coping Inventory for Stressful Situations. Data about caregivers' demographic characteristics, levels of burden, depression and anxiety (psychological distress) were also gathered by standardised questionnaires. Patients' clinical, cognitive and behavioural disturbances were evaluated by ALS specific assessment tools. Sequential logistic regression analysis showed that emotion-oriented coping strategy was significantly associated with high levels of depressive (p < 0.01) and anxiety (p < 0.05) symptoms and high levels of burden (p < 0.05), after controlling for all other variables. Moreover, a significant relationship of patients' functional dependence levels with burden experienced by caregivers was observed. No relationships were detected between task-oriented and avoidance-oriented coping strategies and caregivers' levels of psychological distress. The present study supported the mediating effects of coping strategies on intensity of burden, depression and anxiety experienced by ALS caregivers. These findings suggest that interventions aimed at reducing utilisation of maladaptive coping strategies may improve well-being in ALS caregivers, and, possibly, management of symptoms in ALS patients.

We examined the prevalence of child maltreatment as measured by the level of physical (moderate to severe) and emotional abuse and child labor, and the associated household level determinants of child maltreatment in Nepal. We used a nationally representative data set from the fifth round of the Nepal Multiple Indicator Cluster Survey (the 2014 NMICS). The main independent variables were household level characteristics. Dependent variables included child experience of moderate to severe physical abuse, emotional abuse, and child labor (domestic work and economic activities). Bivariate analyses and logistic regressions were used to examine the associations between independent and dependent variables. The results showed that nearly half of the children (49.8%) had experienced moderate physical abuse, 21.5% experienced severe physical abuse, and 77.3% experienced emotional abuse. About 27% of the children had engaged in domestic work and 46.7% in various economic activities. At bivariate level, educational level of household's head and household wealth status had shown significant statistical association with child maltreatment (p<0.001). Results from multivariate logistic regressions showed that higher education levels and higher household wealth status protected children from moderate to severe physical abuse, emotional abuse and child labor. In general, child maltreatment is a neglected social issue in Nepal and the high rates of child maltreatment calls for mass awareness programs focusing on parents, and involving all stakeholders including governments, local, and international organizations.

Do you have what it takes for challenging endoscopic submucosal dissection cases?

PubMed Central

Kim, Kyoung-Oh; Kim, Sung Jung; Kim, Tae Hyeon; Park, Jong-Jae

2011-01-01

Endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric cancer (EGC), especially in Korea and Japan. The criteria for the therapeutic use of ESD for EGC have been expanded recently. However, attention should be drawn to the technical feasibility of the ESD treatment which depends on a lesion’s location, size or fibrosis level, or operator’s experience. In the case of a lesion with a high level of difficulty, a more experienced operator is required. Thus, the treatment for a lesion with a high level of difficulty should be performed according to the degree of the operator’s experience. In this paper, the authors describe the ESD procedure for lesions with a high level of difficulty. PMID:21987603

Bullying is a form of violence characterized as an aggressive behavior that is unprovoked and intended to cause harm. Prior studies have found that lesbian, gay, bisexual, and transgender (LGBT) youth experience high levels of bullying related to their sexuality and this harassment can lead to engagement in risk behaviors, depression, and suicide. Ethnic/racial minority young men who have sex with men (YMSM) may experience dual levels of stigma and maltreatment due to both their sexuality and their race. The aim of the current study was to assess the prevalence and perceptions of racial and sexual identity-based abuse among a sample of minority YMSM, and whether this maltreatment plays a role in the emotional distress of these youth. We found that overall 36% and 85% of participants experienced racial and sexuality-related bullying, respectively. There was a significant association between experiencing a high level of sexuality-related bullying and depressive symptomatology (p=0.03), having attempted suicide (p=0.03), and reporting parental abuse (p=0.05). We found no association between racial bullying and suicide attempts. In a multivariable logistic regression model, experiencing any racial bullying and high sexuality-related bullying were significant predictors of having a CES-D score ≥16; adjusted odds ratio (OR) 1.83 and 2.29, respectively. These findings contribute to the existing literature regarding the negative experiences and daily stressors facing LGBT youth with regard to both their minority status and LGBT identities. Future interventions for racial/ethnic minority YMSM should provide assistance to achieve a positive view of self that encompasses both their racial and sexual identities.

This study aimed to identify the emotional labor and workplace violence status among toll collectors by assessing and comparing the same with that in workers in other service occupation. It also aimed to analyze the relationship between emotional labor and workplace violence. This study examined emotional labor and workplace violence status in 264 female toll collectors from August 20 to September 4, 2015. The emotional labor was assessed using the Korean Emotional Labor Scale (K-ELS), and a questionnaire was used to examine the presence or absence, and type and frequency of workplace violence experienced by the subjects. A linear regression analysis was also performed to analyze the relationship between workplace violence and emotional labor. The scores on "emotional demanding and regulation ( p  < 0.001)," "overload and conflict in customer service ( p  = 0.005)," "emotional disharmony and hurt ( p  < 0.001)," and "organizational surveillance and monitoring ( p  < 0.001)" among the sub-categories of emotional labor were significantly high and indicated "at-risk" levels of emotional labor in those who experienced workplace violence, whereas they were "normal" of emotional labor in those who did not. Even after being adjusted in the linear regression analysis, the emotional labor scores for the above 4 sub-categories were still significantly high in those who experienced workplace violence. On comparing the present scores with 13 other service occupations, it was found that toll collectors had the highest level in "emotional disharmony and hurt," "organizational surveillance and monitoring," and "organizational supportive and protective system". This study found that the toll collectors engaged in a high level of emotional labor. Additionally, there was a significant relationship between emotional labor and the experience of workplace violence among the toll collectors.

Dental implant failure and insufficient osseointegration are proven results of mechanical and thermal damage during the surgery process. We herein performed a comparative study of a less invasive single-step drilling preparation protocol and a conventional multiple drilling sequence. Accuracy of drilling holes was precisely analyzed and the influence of different levels of expertise of the handlers and additional use of drill template guidance was evaluated. Six experimental groups, deployed in an osseous study model, were representing template-guided and freehanded drilling actions in a stepwise drilling procedure in comparison to a single-drill protocol. Each experimental condition was studied by the drilling actions of respectively three persons without surgical knowledge as well as three highly experienced oral surgeons. Drilling actions were performed and diameters were recorded with a precision measuring instrument. Less experienced operators were able to significantly increase the drilling accuracy using a guiding template, especially when multi-step preparations are performed. Improved accuracy without template guidance was observed when experienced operators were executing single-step versus multi-step technique. Single-step drilling protocols have shown to produce more accurate results than multi-step procedures. The outcome of any protocol can be further improved by use of guiding templates. Operator experience can be a contributing factor. Single-step preparations are less invasive and are promoting osseointegration. Even highly experienced surgeons are achieving higher levels of accuracy by combining this technique with template guidance. Hereby template guidance enables a reduction of hands-on time and side effects during surgery and lead to a more predictable clinical diameter.

Effects of mannose-binding lectin polymorphisms on irinotecan-induced febrile neutropenia.

Mannose-binding lectin (MBL) is important in the innate immune response. MBL2 gene polymorphisms affect MBL expression, and genotypes yielding low MBL levels have been associated with an elevated risk for infections in hematological cancer patients undergoing chemotherapy. However, these reported associations are inconsistent, and data on patients with solid tumors are lacking. Here, we investigated the effects of MBL2 genotypes on irinotecan-induced febrile neutropenia in patients with solid tumors. Irinotecan-treated patients were genotyped for the MBL2 gene. Two promoter (-550 H/L and -221 X/Y) and three exon polymorphisms (52 A/D, 54 A/B, and 57 A/C) were determined, together with known risk factors for irinotecan-induced toxicity. Neutropenia and febrile neutropenia were recorded during the first course. Of the 133 patients, 28% experienced severe neutropenia and 10% experienced febrile neutropenia. No associations were found between exon polymorphisms and febrile neutropenia. However, patients with the H/H promoter genotype, associated with high MBL levels, experienced significantly more febrile neutropenia than patients with the H/L and L/L genotypes (20% versus 13% versus 5%). Moreover, patients with the HYA haplotype encountered significantly more febrile neutropenia than patients without this high MBL-producing haplotype (16% versus 4%). In the subgroup with wild-type exon polymorphisms (A/A), patients with the high MBL promoter phenotype had the highest incidence of febrile neutropenia, regardless of known risk factors. Patients with high MBL2 promoter genotypes and haplotypes seem more at risk for developing febrile neutropenia. If confirmed, these preliminary findings may contribute to more individualized approaches of irinotecan treatment.

A large field of research seeks to explore and understand the factors that may cause different rates of age-related cognitive decline within the general population. However, the impact of experienced stress on the human aging process has remained an under-researched possibility. This study explored the association between cumulative stressful experiences and cognitive aging, addressing whether higher levels of experienced stress correlate with impaired performance on 2 working memory tasks. Behavioral performance was paired with electroencephalographic recordings to enable insight into the underlying neural processes impacted on by cumulative stress. Thus, the electroencephalogram was recorded while both young and elderly performed 2 different working memory tasks (a Sternberg and N-back paradigm), and cortical oscillatory activity in the theta, alpha, and gamma bandwidths was measured. Behavioral data indicated that a higher stress score among elderly participants related to impaired performance on both tasks. Electrophysiological findings revealed a reduction in alpha and gamma event-related synchronization among high-stress-group elderly participants, indicating that higher levels of experienced stress may impact on their ability to actively maintain a stimulus in working memory and inhibit extraneous information interfering with successful maintenance. Findings provide evidence that cumulative experienced stress adversely affects cognitive aging. Copyright © 2015 Elsevier Inc. All rights reserved.

Help-Seeking among Male Employees in Japan: Influence of Workplace Climate and Distress

Maekawa, Yumiko; Ramos-Cejudo, Juan; Kanai, Atsuko

2016-01-01

Objectives: Although using mental health services is an effective way to cope with work-related stressors and diseases, many employees do not utilize these services despite service improvements in recent years. The present study aimed to investigate the interaction effects of workplace climate and distress on help-seeking attitudes, and elucidate the reasons for mental health service underutilization in Japan. Methods: A questionnaire was distributed to 650 full-time male Japanese employees. Hierarchical multiple regression analysis was used to investigate interaction effects of workplace climate and distress on help-seeking. Results: Results showed that the association between workplace climate and help-seeking attitudes differed depending on employee distress level. For employees experiencing low levels of distress, openness to seeking treatment increased with a higher evaluation of the mental health services available at the workplace. However, the same did not hold true for employees experiencing high levels of distress. Instead, openness to seeking treatment decreased with perceived risk for career disadvantage for high distress employees. Additionally, negative values for seeking treatment in highly distressed employees decreased only when services were perceived as valuable, and the risk to their career was perceived as low. Conclusions: Overall, these findings indicate that distress distorts the perception of social support, which may lead to underutilization of available services. Assessing employees' distress levels and tailoring adequate interventions could facilitate help-seeking in male employees. PMID:27725378

Transgender female sex workers’ HIV knowledge, experienced stigma, and condom use in the Dominican Republic

Introduction Not only do transgender female sex workers have some of the highest rates of sexually transmitted infections (STI), human immunodeficiency virus (HIV), and experienced stigma, they also have higher likelihood of early sexual debut and some of the lowest levels of educational attainment compared to other stigmatized populations. Some of the most common interventions designed to reduce transmission of HIV and STIs seek to educate high-risk groups on sexual health and encourage condom use across all partner types; however, reaching stigmatized populations, particularly those in resource-limited settings, is particularly challenging. Considering the importance of condom use in stopping the spread of HIV, the aim of this study was two-fold; first to characterize this hard-to-reach population of transgender female sex workers in the Dominican Republic, and second, to assess associations between their HIV knowledge, experienced stigma, and condom use across three partner types. Methods We analyzed self-reported data from the Questionnaire for Transgender Sex Workers (N = 78). Respondents were interviewed at their workplaces. Univariate and bivariate analyses were employed. Fisher Chi-square tests assessed differences in HIV knowledge and experienced stigma by condom use across partner types. Results HIV knowledge was alarmingly low, condom use varied across partner type, and the respondents in our sample had high levels of experienced stigma. Average age of first sexual experience was 13.12 years with a youngest age reported of 7. Dominican Republic statutory rape laws indicate 18 years is the age of consent; thus, many of these transgender women’s first sexual encounters would be considered forcible (rape) and constitute a prosecutable crime. On average, respondents reported 8.45 sexual partners in the prior month, with a maximum of 49 partners. Approximately two thirds of respondents used a condom the last time they had sex with a regular partner. This was considerably lower than condom use reported with coercive partners (92.96%) and clients (91.78%). Bivariate analyses revealed two trends: experienced stigma was associated with lower rates of condom use, and lower HIV knowledge was associated with lower rates of condom use. The former provides additional evidence that experienced stigma may become internalized, affecting individual-level behaviors—lowering self-confidence and resilience—making it more difficult to negotiate condom use due to lack of self-efficacy and desire to show trust in one’s partner. The latter supports public health research that suggests gaps in HIV knowledge persist and are pronounced in highly stigmatized populations. Discussion The vulnerabilities experienced by transgender persons, particularly in environments that vehemently adhere to conservative ideologies related to sex and gender, are significant and harm this population. These vulnerabilities could potentially be addressed through critically examining of impact of policies that indirectly promote or allow victimization of transgender citizens and subsequently diminish the effectiveness of public health and educational interventions. By taking action through the revocation of such laws, the Dominican Republic has the opportunity to improve overall population health, to protect some of its most stigmatized citizens, and to become the flag bearer of enhanced human rights in the Caribbean and Latin America.

2002-05-01

The author collected data on serum cholesterol, blood pressure, and self-reported health behavior in 226 college students aged 18 to 26 years. Twenty-nine percent had undesirable total cholesterol levels, 10% had high cholesterol, 10% had high systolic blood pressure, and 11% had high diastolic blood pressure. Half or more of the participants consumed a diet high in saturated fats, engaged in binge drinking, had a parental risk for high cholesterol or blood pressure, or reported they experienced elevated stress levels. Men had higher risk-factor levels than women. Findings from a regression analysis revealed that smoking, binge drinking, lack of cardiovascular exercise, and eating a high saturated-fat diet were predictive of undesirable cholesterol levels. Study limitations included self-selection of participants and single measurements of blood pressure and cholesterol. Trained students served as screeners in the program for providing an effective, low-cost screening intervention.

To describe the sleep characteristics and examine the associations among perceived stress, sleep disturbances, depressive symptoms, and physical symptoms among female college students. A total of 103 students completed a battery of questionnaires. The students experienced high stress during the school year. The majority of them slept less than 6 hours during weekdays and experienced moderate fatigue. High stress levels are associated with sleep disturbances, less nocturnal total sleep time, higher fatigue severity, and more depressive symptoms. Perceived stress and sleep disturbances are significant predictors for depressive symptoms and physical symptoms. Compared to the good sleepers, the poor sleepers reported more daytime sleepiness, depressive symptoms, and physical symptoms. Interventions to reduce stress and improve sleep are critically needed in college education.

Humans are a cooperative species, capable of altruism and the creation of shared norms that ensure fairness in society. However, individuals with different educational, cultural, economic, or ethnic backgrounds differ in their levels of social investment and endorsement of egalitarian values. We present four experiments showing that subtle cues to social status (i.e., prestige and reputation in the eyes of others) modulate prosocial orientation. The experiments found that individuals who experienced low status showed more communal and prosocial behavior, and endorsed more egalitarian life goals and values compared with those who experienced high status. Behavioral differences across high- and low-status positions appeared early in human ontogeny (4–5 y of age). PMID:25561527

This study examined effects of the autonomy-connectedness components sensitivity to others, self-awareness and capacity for managing new situations on anger experience versus anger expression in adolescent boys and girls. One hundred thirty-one high school students were randomly assigned to an anger-inducing or neutral condition using the Dictator Game. Whereas after anger induction boys experienced and expressed anger independent of autonomy-connectedness, girls' anger experience depended on the level of sensitivity to others: girls experienced increased anger only when they scored high on sensitivity to others. However, girls' expression of anger did not depend on the level of sensitivity to others. Effects of self-awareness and capacity for managing new situations were found when anger was not induced. This study contributed to emotion regulation research by showing differences in anger experience and anger expression as a function of autonomy-connectedness in boys and girls.

2009-05-01

The aim of this study was to examine the relationship between children's experiences of three different types of violence and academic achievement among primary school children in Kingston, Jamaica. A cross-sectional study of 1300 children in grade 5 [mean (S.D.) age: 11 (0.5) years] from 29 government primary schools in urban areas of Kingston and St. Andrew, Jamaica, was conducted. Academic achievement (mathematics, reading, and spelling) was assessed using the Wide Range Achievement Test. Children's experiences of three types of violence - exposure to aggression among peers at school, physical punishment at school, and exposure to community violence - were assessed by self-report using an interviewer administered questionnaire. Fifty-eight percent of the children experienced moderate or high levels of all three types of violence. Boys had poorer academic achievement and experienced higher levels of aggression among peers and physical punishment at school than girls. Children's experiences of the three types of violence were independently associated with all three indices of academic achievement. There was a dose-response relationship between children's experiences of violence and academic achievement with children experiencing higher levels of violence having the poorest academic achievement and children experiencing moderate levels having poorer achievement than those experiencing little or none. Exposure to three different types of violence was independently associated with poor school achievement among children attending government, urban schools in Jamaica. Programs are needed in schools to reduce the levels of aggression among students and the use of physical punishment by teachers and to provide support for children exposed to community violence. Children in Jamaica and the wider Caribbean experience significant amounts of violence in their homes, communities, and schools. In this study, we demonstrate a dose-response relationship between primary school children's experiences of three different types of violence and their academic achievement. The study points to the need for validated violence prevention programs to be introduced in Jamaican primary schools. Such programs need to train teachers in appropriate classroom management and discipline strategies and to promote children's social and emotional competence and prevent aggression.

Hospital experience and mortality in patients with systemic lupus erythematosus: which patients benefit most from treatment at highly experienced hospitals?

To determine if hospitalization at a hospital experienced in the treatment of systemic lupus erythematosus (SLE), compared to hospitalization at a less experienced hospital, is associated with decreased in-hospital mortality in all subsets of patients with SLE, or if the decrease in mortality is greater for patients with particular demographic characteristics, manifestations of SLE, or reasons for hospitalization. Data on in-hospital mortality were available for 9989 patients with SLE hospitalized in acute care hospitals in California from 1991 to 1994. Differences in in-hospital mortality between patients hospitalized at highly experienced hospitals (those hospitals with more than 50 urgent or emergent hospitalizations of patients with SLE per year) and those hospitalized at less experienced hospitals were compared in patient subgroups defined by age, sex, ethnicity, type of medical insurance, the presence of common SLE manifestations, and each of the 10 most common principal reasons for hospitalization. In univariate analyses, in-hospital mortality was lower among those hospitalized at a highly experienced hospital for women, blacks, and Hispanics, and those with public medical insurance or no insurance. The risk of in-hospital mortality was similar between highly experienced and less experienced hospitals for men, whites, and those with private insurance. Patients with nephritis also had lower risks of in-hospital mortality if they were hospitalized at highly experienced hospitals, but this risk did not differ in subgroups with other SLE manifestations or subgroups with different principal reasons for hospitalization. In multivariate analyses, only the interaction between medical insurance and hospitalization at a highly experienced hospital was significant. Results were similar in the subgroup of patients with an emergency hospitalization (n = 2,372), but more consistent benefits of hospitalization at a highly experienced hospital were found across subgroups of patients with an emergency hospitalization due to SLE (n = 405). Risks of in-hospital mortality for patients with SLE were similar between highly experienced hospitals and less experienced hospitals for patients with private medical insurance, but patients without private insurance had much lower risks of mortality if hospitalized at highly experienced hospitals. The benefit of hospitalization at highly experienced hospitals was more consistent across subgroups of patients with a hospitalization due to SLE, suggesting that differences specifically in the treatment of SLE, rather than differences in the general quality of medical care, account for the lower mortality among patients with SLE hospitalized at highly experienced hospitals.

Stress responses among parents of premature infants experiencing the neonatal intensive care unit (NICU) environment are widely reported. However, less is known about how nurses perceive parents' experiences or how stressors relating to demands on family finances and practical challenges associated with infant hospitalization contribute to parental stress levels in the NICU. 1) To compare parent and staff perceptions of the stressors facing parents experiencing neonatal intensive care; and 2) to develop a scale suitable for identifying stressors outside the NICU setting. At infant 34 weeks, parents (n=21) of very preterm infants (≤ 32 weeks GA) and NICU nurses (n=23) completed the Parental Stressor Scale: NICU (PSS: NICU) and a custom-made External Stressor Scale (ESS: NICU). Nurses perceived parents to experience higher stress in the NICU than parents themselves (ps<0.00001), with parents reporting low-to-moderate stress and staff rating parental stress as moderate-to-high. Parents reported slightly lower levels of stress on the ESS: NICU, with nurses again overestimating the level of parental stress (ps<0.00001). Consideration of the extent of nurses' medical experience did not alter results. The ESS: NICU showed good internal reliability, with PCAs revealing all items to load onto a single component. Additional analyses demonstrated divergent validity, with no relation evident with stress responses on the PSS: NICU. Periodic reassessments of staff and parent perceptions should be encouraged along with research dedicated to a fuller understanding of the range of stressors facing parents experiencing neonatal intensive care in attempts to reduce stress levels and aid integration into the unit.

Experienced and Anticipated Pride and Shame as Predictors of Goal-Directed Behavior.

PubMed

Gilchrist, Jenna D; Conroy, David E; Sabiston, Catherine M

2017-12-01

This study examined how experienced and anticipated pride and shame were related to time spent training and effort expended toward training the following week. Participants (N = 158, 76% women; M age  = 35.51, SD = 10.29 years) training for a marathon/half-marathon completed a weekly online questionnaire for 5 weeks leading up to a race. In the multilevel models, time spent training was positively predicted by race proximity, age, and effort expended that week. Effort expended toward training was predicted by the current week's effort, the amount of time spent training that week, and was greater for participants who usually reported experiencing more pride than others. Neither anticipated pride or shame predicted time or effort, nor did experienced shame. The findings indicate that it is functional to foster high levels of pride when training for a long-distance race. Further work is needed to ascertain the relationship between anticipated emotions on goal-directed behavior.

To establish the prevalence and characteristics of occupational violence in Australian urban general practice, and examine practitioner correlates of violence. Cross-sectional questionnaire survey mailed to all members (n = 1085) of three urban divisions of general practice in New South Wales in August and September 2004. The three divisions were chosen to provide a range of socioeconomic status (SES) demographics. Occupational violence towards general practitioners during the previous 12 months. 528 GPs returned questionnaires (49% response rate). Of these, 63.7% had experienced violence in the previous year. The most common forms of violence were "low level" violence - verbal abuse (42.1%), property damage/theft (28.6%) and threats (23.1%). A smaller proportion of GPs had experienced "high level" violence, such as sexual harassment (9.3%) and physical abuse (2.7%). On univariate analysis, violence was significantly more likely towards female GPs (P < 0.001), less experienced GPs (P = 0.003) and GPs working in a lower SES status area (P < 0.001), and among practice populations encompassing greater social disadvantage (P = 0.006), mental health problems (P < 0.001), and drug- and alcohol-related problems (P < 0.001). Experience of violence was greater for younger GPs (P = 0.005) and those providing after-hours care (P = 0.033 for after-hours home visits). On multivariate analysis, a significant association persisted between high level violence and lower SES area (odds ratio [OR], 2.86), being female (OR, 5.87), having practice populations with more drug-related problems (OR, 5.77), and providing home visits during business hours (OR, 4.76). More experienced GPs encountered less violence (OR, 0.77) for every additional 5 years of practice. Occupational violence is a considerable problem in Australian urban general practice. Formal education programs in preventing and managing violence would be appropriate for GPs and doctors-in-training.

India has around 2.27 million adults living with HIV/AIDS who face several challenges in the medical management of their disease. Stigma, discrimination and psychosocial issues are prevalent. The objective of the study was to determine the prevalence of severe stigma and to study the association between this, depression and the quality of life (QOL) of people living with HIV/AIDS (PLHA) in Tamil Nadu. This was a community based cross sectional study carried out in seven districts of Tamil Nadu, India, among 400 PLHA in the year 2009. The following scales were used for stigma, depression and quality of life, Berger scale, Major Depression Inventory (MDI) scale and the WHO BREF scale. Both Stigma and QOL were classified as none, moderate or severe/poor based on the tertile cut off values of the scale scores. Depression was classified as none, mild, moderate and severe. Logistic regression analyses were performed to study the risk factors. Twenty seven per cent of PLHA had experienced severe forms of stigma. These were severe forms of personalized stigma (28.8%), negative self-image (30.3%), perceived public attitude (18.2%) and disclosure concerns (26%). PLHA experiencing severe depression were 12% and those experiencing poor quality of life were 34%. Poor QOL reported in the physical, psychological, social and environmental domains was 42.5%, 40%, 51.2% and 34% respectively. PLHA who had severe personalized stigma and negative self-image had 3.4 (1.6-7.0) and 2.1 (1.0-4.1) times higher risk of severe depression respectively (p < .001). PLHA who had severe depression had experienced 2.7(1.1-7.7) times significantly poorer QOL. Severe forms of stigma were equivalently prevalent among all the categories of PLHA. However, PLHA who had experienced severe depression had only developed poor QOL. A high level of social support was associated with a high level of QOL.

Level and appraisal of fatigue are not specific in burnout.

Fatigue is a main feature of the burnout syndrome but also very common in other psychiatric disorders such as major depression and anxiety disorders. This raises the question of whether the level and appraisal of fatigue is experienced differently by individuals suffering from burnout than by those exhibiting anxiety disorders and major depression. If fatigue is experienced differently in burnout compared with other disorders, this may clarify why fatigue is the main feature of the burnout syndrome. This knowledge may lead to the application of specific therapeutic interventions aimed at the experience of fatigue in burnout. In the present study, we investigated whether fatigue is experienced differently in burnout patients than in patients suffering from anxiety disorders or major depression. We presented 73 burnout patients, 67 depressed patients, 57 patients with an anxiety disorder and 127 healthy participants with a rating scale containing statements about the fatigue-performance relationship, and we assessed the level of fatigue, depression and anxiety. The level of fatigue reported by burnout patients was high but did not differ from that of the other patient groups. The appraisal of fatigue also did not differ among the patient groups. The burnout patients did not appraise their fatigue as a result of unrewarding activities nor did they catastrophize fatigue in an exceptional way. Thus, the level of fatigue and the appraisal of fatigue may be less relevant to the understanding of the specific pathological processes associated with burnout than is often presumed.

We examined the hypothesis that stress-related blunting of cortisol in smokers is particularly pronounced in those with a history of severe life adversity. The two aims of this study were first to examine hormonal, craving, and withdrawal symptoms during ad libitum smoking and after the first 24 h of abstinence in smokers who experienced high or low levels of adversity. Second, we sought to examine the relationship between adversity and hypothalamic-pituitary-adrenal (HPA) hormones to predict relapse during the first month of a smoking cessation attempt. Hormonal and self-report measures were collected from 103 smokers (49 women) during ad libitum smoking and after the first 24 h of abstinence. HPA hormones were measured during baseline rest and in response to acute stress in both conditions. All smokers were interested in smoking cessation, and we prospectively used stress response measures to predict relapse during the first 4 weeks of the smoking cessation attempt. The results showed that high adversity was associated with higher distress and smoking withdrawal symptoms. High level of early life adversity was associated with elevated HPA activity, which was found in both salivary and plasma cortisol. Enhanced adrenocorticotropic hormone (ACTH) stress response was evident in high-adversity but not in low-adversity relapsers. This study demonstrated that early life adversity is associated with stress-related HPA responses. The study also demonstrated that, among smokers who experienced a high level of life adversity, heightened ACTH and cortisol responses were linked with increased risk for smoking relapse.

This study aimed to examine the associations of suicidality in emerging adulthood with time of coming out, gender role nonconformity, sexual orientation, traditional and cyber homophobic bullying victimization, and family and peer support during childhood in gay and bisexual men in Taiwan. The frequency of "experiencing suicide ideation" and "attempting suicide" in the past year among 500 gay or bisexual men was examined. The participants' time of coming out, level of subjective masculinity, sexual orientation, experiences of traditional and cyber homophobic bullying victimization, and levels of family and peer support during childhood were also evaluated. In total, 31% (n = 155) of participants reported experiencing suicide ideation (n = 82) or attempting suicide (n = 73). Early coming out, traditional homophobic bullying victimization, and low family support during childhood increased the risk of suicidality in emerging adulthood; by contrast, family support did not moderate the association of early coming out or traditional bullying victimization with current suicidality. A high proportion of participants reported experiencing suicide ideation and attempt in emerging adulthood. Hence, effective suicide prevention is required for gay and bisexual men. Suicide prevention programs should consider time of coming out, traditional homophobic bullying victimization, and level of family support. © 2018 The American Association of Suicidology.

Psychosocial oncologists may be particularly vulnerable to burnout. This study aimed to assess burnout among Israeli psychosocial oncologists in relation to the Job Demands-Resources model and the coping strategies model. Participants included 85 of 128 listed psychosocial oncologists currently working with cancer patients. They completed a questionnaire assessing emotional exhaustion, depersonalization, job demands, job resources, work engagement, overcommitment, and perceived value of work. The mean level of burnout was low, whereas 16.3% experienced high levels of emotional exhaustion and only 2.4% experienced high levels of depersonalization. According to mediation analysis, overcommitment, partially mediated job demands-burnout associations, and work engagement mediated the perceived value-burnout association. Job resources and burnout were not related, either directly or indirectly. Significance of results The study extended the Job Demands-Resources model to include perceived value as an additional resource, and work-engagement and overcommitment as coping strategies. Two distinct patterns of associations were found between work characteristics and burnout: the positive-protective pattern (perceived value and work engagement) and the negative pattern (job demands and overcommitment). These two patterns should be considered for further research and for implementing preventive interventions to reduce burnout in the workplace setting.

High income and wealth inequality corresponds with high rates of various health and social problems. One possible factor that could be contributing to this correlation is stress experienced by those being treated unfairly in an unequal society. The present experiment attempted to simulate aspects of income inequality in a lab setting while recording several measures of stress. Participants (n=96) were assigned to one of four groups and played a memory game against a confederate opponent to earn "money" to spend in a lab market. The four groups depended on the difficulty of the problems and the fairness of the game that they and their opponents experienced. Stress attitudes were assessed with the Short Stress State Questionnaire (SSSQ) and four physiological measures: salivary cortisol, medial frontalis and corrugator facial muscle EMG, heart rate, heart rate variability (HRV), and skin conductance levels (SCL). Cortisol levels and HRV scores were the highest in groups that competed in an unfair game regardless of the difficulty of the problem compared to the groups playing a fair game. The group playing an unfair game with hard problems (disadvantaged) also had elevated facial muscle activity indicating negative affect and reported higher distress on the stress questionnaire. The results of this experiment showed that experiencing inequality even for a short time elicited several stress responses even if the participant benefited from the inequality.

This article presents the findings of a study that examined the rates and the consequences of exposure to community violence (ECV) as reflected in witnessing and experiencing such violence, among Palestinian adolescents from Israel. In particular, it examined the extent to which these adolescents exhibit high levels of internalizing and externalizing symptoms as consequences of such exposure, and the extent to which self-efficacy and collective efficacy moderate these consequences. A systematic random sample of 760 Palestinian adolescents in Israel (320 boys, and 440 girls) filled out a self-administered questionnaire. The results show that most of the adolescents had witnessed community violence during the last year and during lifetime, and more than one third had directly experienced such violence during their lifetime compared with 19.6% during the last year. Boys were exposed to community violence more often than girls. Moreover, participants' ECV predicted high levels of externalizing and internalizing symptoms. Hierarchical regression analysis revealed that collective efficacy moderated the correlation between experiencing community violence and internalizing symptoms, whereas self-efficacy moderated the correlation between witnessing community violence and externalizing symptoms. There is a need for providing support for youth from close adults as well as from formal and informal resources in the community before and after their ECV. Copyright © 2018 Elsevier Ltd.

Falls and Hospitalizations Among Persons With Dementia and Associated Caregiver Emotional Difficulties.

PubMed

Leggett, Amanda N; Polenick, Courtney A; Maust, Donovan T; Kales, Helen C

2018-03-19

Falls and hospitalizations are adverse health events commonly experienced by persons with dementia (PWDs). These events often require urgent care from a family caregiver and may increase caregiver stress. We examine falls and hospitalizations among PWDs as predictors of caregivers' reported care-related emotional difficulty, in addition to care-related stressors. Cross-sectional telephone survey of 652 informal caregivers for PWDs. A multinomial logistic regression examined falls (last month) and hospitalizations (prior year) experienced by PWDs as predictors of caregivers' care-related emotional difficulty, accounting for demographic characteristics and primary and secondary caregiving stressors. Over 20% of caregivers reported high levels of care-related emotional difficulty. Controlling for demographic characteristics and primary and secondary caregiving stressors, the PWD's prior month fall was significantly associated with greater care-related emotional difficulty; the PWD's hospitalizations were not associated with care-related emotional difficulty. Approximately 30% of PWDs had experienced a past year hospitalization and prior month fall, and one in five caregivers reported high emotional difficulty related to care. Although secondary strains and resources of caregiving were strong predictors of care-related emotional difficulty, PWDs' falls represent a significant stressor that increases odds of caregiver emotional difficulty over and above other strains. Consequently, a fall experienced by a PWD may represent a key time for clinicians to assess caregiver well-being.

2018-06-01

Fatigue sensation is an essential biological alarm that urges us to take rest to avoid disrupting homeostasis and thus plays an important role in maintaining well-being. However, there are situations in which the anticipation of unpleasant fatigue sensation undesirably reduces motivation for activity. The aim of this study was to examine whether thinking positively about the fatigue sensation would increase motivation to accomplish the workload. Fourteen healthy male volunteers participated in this study and performed a two-back test for 30 min to induce mental fatigue sensation. After their subjective level of fatigue had recovered to the baseline level, they re-experienced the fatigue sensation experienced in the two-back test positively, negatively, and without any modification (i.e., re-experienced the fatigue sensation as it was). The level of motivation to perform another two-back test they felt during the re-experiencing was assessed. The neural activity related to the re-experiencing was recorded using magnetoencephalography. The level of the motivation to perform another two-back test was increased by positively re-experiencing the fatigue sensation. The increase in delta band power in Brodmann area 7 was positively associated with the increase in motivation. These results show that positive thinking about fatigue sensation can enhance motivation and suggest that this enhanced motivation may have some effects on visual attention system.

Learning to learn and learning to cooperate are two important goals for individuals. Moreover, self regulation has been identified as fundamental to prevent school failure. The goal of the present study was to assess the interactions between self-regulated learning, cooperative learning and academic self-efficacy in secondary education students experiencing cooperative learning as the main pedagogical approach for at least one school year. 2.513 secondary education students (1.308 males, 1.205 females), 12–17 years old (M = 13.85, SD = 1.29), enrolled in 17 different schools belonging to the National Network of Schools on Cooperative Learning in Spain agreed to participate. They all had experienced this pedagogical approach a minimum of one school year. Participants were asked to complete the cooperative learning questionnaire, the strategies to control the study questionnaire and the global academic self-efficacy questionnaire. Participants were grouped based on their perceptions on cooperative learning and self-regulated learning in their classes. A combination of hierarchical and κ-means cluster analyses was used. Results revealed a four-cluster solution: cluster one included students with low levels of cooperative learning, self-regulated learning and academic self-efficacy, cluster two included students with high levels of cooperative learning, self-regulated learning and academic self-efficacy, cluster three included students with high levels of cooperative learning, low levels of self-regulated learning and intermediate-low levels of academic self-efficacy, and, finally, cluster four included students with high levels of self-regulated learning, low levels of cooperative learning, and intermediate-high levels of academic self-efficacy. Self-regulated learning was found more influential than cooperative learning on students’ academic self-efficacy. In cooperative learning contexts students interact through different types of regulations: self, co, and shared. Educators should be aware of these interactions, symmetrical or asymmetrical, because they determine the quality and quantity of the students’ participation and achievements, and they are key elements to prevent school failure.

Self-titration is well documented in the tobacco literature. The extent to which e-cigarette users (vapers) self-titrate is unknown. This study explored the effects of high and low nicotine strength liquid on puffing topography, nicotine delivery and subjective effects in experienced vapers. Eleven experienced male vapers completed 60 min of ad libitum vaping under low (6 mg/mL) and high (24 mg/mL) nicotine liquid conditions in two separate sessions. Measurements included puffing topography (puff number, puff duration, volume of liquid consumed) and changes in plasma nicotine levels, craving, withdrawal symptoms, self-reported hit, satisfaction and adverse effects. Liquid consumption and puff number were higher and puff duration longer, in the low nicotine strength condition (all ps < 0.01). The mean difference in nicotine boost from baseline in the low condition was 8.59 (7.52) ng/mL, 16.99 (11.72) ng/mL and 22.03 (16.19) ng/mL at 10, 30 and 60 min, respectively. Corresponding values for the high condition were 33.77 (34.88) ng/mL, 35.48 (28.31) ng/mL and 43.57 (34.78) ng/mL (ps < 0.05). There were no statistically significant differences between conditions in self-reported craving, withdrawal symptoms, satisfaction, hit or adverse effects. Vapers engaged in compensatory puffing with lower nicotine strength liquid, doubling their consumption. Whilst compensatory puffing was sufficient to reduce craving and withdrawal discomfort, self-titration was incomplete with significantly higher plasma nicotine levels in the high condition.

Objective. Mannose-binding lectin (MBL) is important in the innate immune response. MBL2 gene polymorphisms affect MBL expression, and genotypes yielding low MBL levels have been associated with an elevated risk for infections in hematological cancer patients undergoing chemotherapy. However, these reported associations are inconsistent, and data on patients with solid tumors are lacking. Here, we investigated the effects of MBL2 genotypes on irinotecan-induced febrile neutropenia in patients with solid tumors. Patients and Methods. Irinotecan-treated patients were genotyped for the MBL2 gene. Two promoter (−550 H/L and −221 X/Y) and three exon polymorphisms (52 A/D, 54 A/B, and 57 A/C) were determined, together with known risk factors for irinotecan-induced toxicity. Neutropenia and febrile neutropenia were recorded during the first course. Results. Of the 133 patients, 28% experienced severe neutropenia and 10% experienced febrile neutropenia. No associations were found between exon polymorphisms and febrile neutropenia. However, patients with the H/H promoter genotype, associated with high MBL levels, experienced significantly more febrile neutropenia than patients with the H/L and L/L genotypes (20% versus 13% versus 5%). Moreover, patients with the HYA haplotype encountered significantly more febrile neutropenia than patients without this high MBL-producing haplotype (16% versus 4%). In the subgroup with wild-type exon polymorphisms (A/A), patients with the high MBL promoter phenotype had the highest incidence of febrile neutropenia, regardless of known risk factors. Conclusion. Patients with high MBL2 promoter genotypes and haplotypes seem more at risk for developing febrile neutropenia. If confirmed, these preliminary findings may contribute to more individualized approaches of irinotecan treatment. PMID:20930093

The article describes symptoms of anxiety, depression and PTSD among Bosnian (n=17) and Colombian (n=17) torture survivors served by the Florida Center for Survivors of Torture, a programme of Gulf Coast Jewish Family Services, Inc. Information from clients enrolled in the programme for six months or more was collated over a 14 month period in order to better prioritize and design services for the two distinct populations. On average, the Bosnians in this sample experienced torture approximately 14 years ago while the Colombians'experience was approximately six years ago. Types of torture experienced by clients are documented using HURIDOCS and the number of family and friends affected by extreme trauma are counted. Employment and education levels attained are also identified. Findings show that 100% of Bosnians are symptomatic for depression and over half possess symptoms of PTSD compared to 35% of Colombians for depression and 18% for PTSD, despite the differences in years since trauma occurred. High incidences of torture experienced by Bosnian clients and high numbers of family and friends affected support the high rates of symptoms. For the Colombian clients, high rates of employment and years of education, as well as earlier intervention, may contribute to their lower rates of symptoms. The two client groups are distinguished by the unique circumstances experienced by each, including punctuated wartime versus a prolonged insurgency, as well as the refugee versus asylum seeker experience. This exploratory project informs the torture treatment model while recognizing the importance of ethnic, political and cultural perspectives affecting the healing process.

The continuous two bottle choice test is the most common measure of alcohol consumption but there is remarkably little information about the development of tolerance or dependence with this procedure. We showed that C57BL/6JxFVB/NJ and FVB/NJxC57BL/6J F1 hybrid mice demonstrate greater preference for and consumption of alcohol than either parental strain. In order to test the ability of this genetic model of high alcohol consumption to produce neuroadaptation, we examined development of alcohol tolerance and dependence after chronic self-administration using a continuous access two-bottle choice paradigm. Ethanol-experienced mice stably consumed about 16–18 g/kg/day of ethanol. Ethanol-induced withdrawal severity was assessed (after 59 days of drinking) by scoring handling-induced convulsions; withdrawal severity was minimal and did not differ between ethanol-experienced and -naïve mice. After 71 days of drinking, the rate of ethanol clearance was similar for ethanol-experienced and -naïve mice. After 77 days of drinking, ethanol-induced loss of righting reflex (LORR) was tested daily for 5 days. Ethanol-experienced mice had a shorter duration of LORR. For both ethanol-experienced and -naïve mice, blood ethanol concentrations taken at gain of righting reflex were greater on day 5 than on day 1, indicative of tolerance. After 98 days of drinking, ethanol-induced hypothermia was assessed daily for 3 days. Both ethanol-experienced and –naïve mice developed rapid and chronic tolerance to ethanol-induced hypothermia, with significant group differences on the first day of testing. In summary, chronic, high levels of alcohol consumption in F1 hybrid mice produced rapid and chronic tolerance to both the sedative/hypnotic and hypothermic effects of ethanol; additionally, a small degree of metabolic tolerance developed. The development of tolerance supports the validity of using this model of high alcohol consumption in genetic studies of alcoholism. PMID:23313769

Maternal care experienced during postnatal development has enduring effects on neuroendocrine function and behavior. Previous studies in rats have illustrated the effect of maternal licking/grooming (LG) on hormone receptors and maternal behavior of adult female offspring associated with altered DNA methylation. However, the developmental timing of these effects, which provide insight into the cellular and molecular pathways through which early experience alters later behavior, had not been explored. Here, we demonstrate the developmental emergence of these outcomes and use cross-fostering to identify sensitive periods for these effects. Estrogen receptor (ER)α and ERβ mRNA levels within the medial preoptic area (MPOA) of the hypothalamus were increased by postnatal day (PN)21 in female offspring of high LG dams; LG-associated increases in oxytocin receptor mRNA levels were observed beyond the weaning period. Quantification of ERα-immunoreactivity indicated a high degree of neuroanatomical specificity of LG effects within the MPOA that were observed by PN6. Reduced DNA methylation and histone 3 lysine 9 tri-methylation and increased histone 3 lysine 4 tri-methylation at the ERα gene promoter (Esr1) were detected at PN21 in high LG female offspring. Latency to engage in maternal behavior toward donor pups was significantly shorter among high LG females. Cross-fostering revealed that maternal sensitization and MPOA ERα levels are sensitive to maternal care experienced before but not after PN10. Differential windows of plasticity were identified for ERβ and oxytocin receptor mRNA levels. These studies contribute significantly to our understanding of the molecular, neurobiological, and behavioral pathways through which variation in maternal behavior is transmitted from one generation to the next.

The unfair treatment of individuals with severe mental illness has been linked to poorer physical and mental health outcomes. Additionally, anticipation of discrimination may lead some individuals to avoid participation in particular life areas, leading to greater isolation and social marginalisation. This study aimed to establish the levels and clinical and socio-demographic associations of anticipated and experienced discrimination amongst those diagnosed with a schizophrenia and comparator severe mental illnesses (bipolar and major depressive disorders). This study was a cross-sectional analysis of anticipated and experienced discrimination from 202 individuals in South London (47% with schizophrenia, 32% with depression and 20% with bipolar disorder). 93% of the sample anticipated discrimination and 87% of participants had experienced discrimination in at least one area of life in the previous year. There was a significant association between the anticipation and the experience of discrimination. Higher levels of experienced discrimination were reported by those of a mixed ethnicity, and those with higher levels of education. Women anticipated more discrimination than men. Neither diagnosis nor levels of functioning were associated with the extent of discrimination. Clinical symptoms of anxiety, depression and suspiciousness were associated with more experienced and anticipated discrimination respectively. The unfair treatment of individuals with severe mental illnesses remains unacceptably common. Population level interventions are needed to reduce levels of discrimination and to safeguard individuals. Interventions are also required to assist those with severe mental illness to reduce internalised stigma and social avoidance.

EMS personnel often work in unpredictable environments and are at high risk for sustaining occupational injuries. One potential source of injury that is of growing concern is violence toward EMS personnel. To describe the prevalence of violence directed at EMS personnel by type and source, and to identify characteristics associated with experiencing violence. The 2013 Longitudinal EMT Attributes and Demographics Study contained 14 items assessing violence experienced in the past 12 months. Violence was categorized by type (physical or verbal) and by source (the patient or a patient's family member or bystander). EMS personnel characteristics included sex, age, race, marital status, certification level, firefighter, volunteerism, agency type, and community size. Descriptive and comparative analyses were performed on personnel whose primary role was providing patient care. Multivariable logistic regression modelling was used to assess associations between provider characteristics and experiencing violence. A total of 2,515/4,238 (59.3%) responses were received and 1,789 met inclusion criteria. Over two-thirds (69.0%) experienced at least one form of violence in the past 12 months. Verbal violence was more prevalent than physical (67.0% vs. 43.6%). Using multivariable logistic regression to control for other demographic and employment characteristics, paramedics had nearly triple the odds of experiencing physical (OR = 2.67, 95% CI = 2.06-3.46) and verbal (OR = 2.63, 95% CI = 1.99-3.46) violence as EMTs. Urban personnel had increased odds of experiencing physical (OR = 1.53, 95% CI = 1.21-1.93) and verbal violence (OR = 1.32, 95% CI = 1.02-1.71). Each additional weekly transport increased the odds of experiencing physical (OR = 1.04, 95% CI = 1.03-1.05) and verbal (OR = 1.04, 95% CI = 1.03-1.06) violence by 4%. Those who were volunteers at their main EMS jobs had decreased odds of experiencing physical (OR = 0.68, 95% CI = 0.50-0.92) and verbal (OR = 0.59, 95% CI = 0.44-0.78) violence. Over two-thirds of EMS personnel experienced at least one form of violence in the last 12 months. Demographic and employment characteristics associated with experiencing violence were identified. Our findings may be used in education initiatives to raise awareness of the high prevalence of violence toward EMS personnel and factors associated with experiencing violence.

In the present study we quantify stress by measuring transient perspiratory responses on the perinasal area through thermal imaging. These responses prove to be sympathetically driven and hence, a likely indicator of stress processes in the brain. Armed with the unobtrusive measurement methodology we developed, we were able to monitor stress responses in the context of surgical training, the quintessence of human dexterity. We show that in dexterous tasking under critical conditions, novices attempt to perform a task's step equally fast with experienced individuals. We further show that while fast behavior in experienced individuals is afforded by skill, fast behavior in novices is likely instigated by high stress levels, at the expense of accuracy. Humans avoid adjusting speed to skill and rather grow their skill to a predetermined speed level, likely defined by neurophysiological latency. PMID:22396852

Ecologically relevant levels of multiple, common marine stressors suggest antagonistic effects.

PubMed

Lange, Rolanda; Marshall, Dustin

2017-07-24

Stressors associated with global change will be experienced simultaneously and may act synergistically, so attempts to estimate the capacity of marine systems to cope with global change requires a multi-stressor approach. Because recent evidence suggests that stressor effects can be context-dependent, estimates of how stressors are experienced in ecologically realistic settings will be particularly valuable. To enhance our understanding of the interplay between environmental effects and the impact of multiple stressors from both natural and anthropogenic sources, we conducted a field experiment. We explored the impact of multiple, functionally varied stressors from both natural and anthropogenic sources experienced during early life history in a common sessile marine invertebrate, Bugula neritina. Natural spatial environmental variation induced differences in conspecific densities, allowing us to test for density-driven context-dependence of stressor effects. We indeed found density-dependent effects. Under high conspecific density, individual survival increased, which offset part of the negative effects of experiencing stressors. Experiencing multiple stressors early in life history translated to a decreased survival in the field, albeit the effects were not as drastic as we expected: our results are congruent with antagonistic stressor effects. We speculate that when individual stressors are more subtle, stressor synergies become less common.

Thyroid hormone fluctuations indicate a thermoregulatory function in both a tropical (Alouatta palliata) and seasonally cold-habitat (Macaca fuscata) primate.

Thyroid hormones boost animals' basal metabolic rate and represent an important thermoregulatory pathway for mammals that face cold temperatures. Whereas the cold thermal pressures experienced by primates in seasonal habitats at high latitudes and elevations are often apparent, tropical habitats also display distinct wet and dry seasons with modest changes in thermal environment. We assessed seasonal and temperature-related changes in thyroid hormone levels for two primate species in disparate thermal environments, tropical mantled howlers (Alouatta palliata), and seasonally cold-habitat Japanese macaques (Macaca fuscata). We collected urine and feces from animals and used ELISA to quantify levels of the thyroid hormone triiodothyronine (fT 3 ). For both species, fT 3 levels were significantly higher during the cooler season (wet/winter), consistent with a thermoregulatory role. Likewise, both species displayed greater temperature deficits (i.e., the degree to which animals warm their body temperature relative to ambient) during the cooler season, indicating greater thermoregulatory pressures during this time. Independently of season, Japanese macaques displayed increasing fT 3 levels with decreasing recently experienced maximum temperatures, but no relationship between fT 3 and recently experienced minimum temperatures. Howlers increased fT 3 levels as recently experienced minimum temperatures decreased, although demonstrated the opposite relationship with maximum temperatures. This may reflect natural thermal variation in howlers' habitat: wet seasons had cooler minimum and mean temperatures than the dry season, but similar maximum temperatures. Overall, our findings support the hypothesis that both tropical howlers and seasonally cold-habitat Japanese macaques utilize thyroid hormones as a mechanism to boost metabolism in response to thermoregulatory pressures. This implies that cool thermal pressures faced by tropical primates are sufficient to invoke an energetically costly and relatively longer-term thermoregulatory pathway. The well-established relationship between thyroid hormones and energetics suggests that the seasonal hormonal changes we observed could influence many commonly studied behaviors including food choice, range use, and activity patterns. © 2017 Wiley Periodicals, Inc.

Little has been published in Colombia on HIV drug resistance in patients taking antiretroviral treatment (ART). Currently, the Colombian guidelines do not recommend the use of genotypic antiretroviral resistance tests (GART) for treatment-naive patients or for those experiencing a first therapeutic failure. To determine the frequency of relevant resistance mutations and the degree of susceptibility/ resistance of HIV to antiretroviral drugs (ARVs) in ART-experienced patients. A non-random sample of 170 ART-experienced HIV patients with virologic failure and who underwent GART was recruited. A study of HIV drug resistance was carried out in two groups of patients: one group that underwent early GART and the other group that received late GART testing. The most frequent type of resistance affected the non-nucleoside class (76%). The late-GART group had higher risk of nucleoside analog and protease inhibitor drug resistance, a higher number of resistance mutations and more complex mutational profiles than the early-GART group. A high cross resistance level (30%) was found in the nucleoside analog class. The least affected medications were tenofovir and darunavir. Our results suggest that performing GART late is associated with levels of ARV resistance that could restrict the use of an important number of essential ARV in subsequent regimens. There is a need to revise the current recommendations to include GART prior to start of treatment and after the first virologic failure.

Background Psychiatry has been consistently shown to be a profession characterised by ‘high-burnout’; however, no nationwide surveys on this topic have been conducted in Japan. Aims The objective of this study was to estimate the prevalence of burnout and to ascertain the relationship between work environment satisfaction, work-life balance satisfaction and burnout among psychiatrists working in medical schools in Japan. Method We mailed anonymous questionnaires to all 80 psychiatry departments in medical schools throughout Japan. Work-life satisfaction, work-environment satisfaction and social support assessments, as well as the Maslach Burnout Inventory (MBI), were used. Results Sixty psychiatric departments (75.0%) responded, and 704 psychiatrists provided answers to the assessments and MBI. Half of the respondents (n = 311, 46.0%) experienced difficulty with their work-life balance. Based on the responses to the MBI, 21.0% of the respondents had a high level of emotional exhaustion, 12.0% had a high level of depersonalisation, and 72.0% had a low level of personal accomplishment. Receiving little support, experiencing difficulty with work-life balance, and having less work-environment satisfaction were significantly associated with higher emotional exhaustion. A higher number of nights worked per month was significantly associated with higher depersonalisation. Conclusions A low level of personal accomplishment was quite prevalent among Japanese psychiatrists compared with the results of previous studies. Poor work-life balance was related to burnout, and social support was noted to mitigate the impact of burnout. PMID:23418435

The Role of Informal Support Networks in Teaching the Nature of Science

Herman, Benjamin C.; Olson, Joanne K.; Clough, Michael P.

2017-06-01

This study reports the participation of 13 secondary science teachers in informal support networks and how that participation was associated with their nature of science (NOS) teaching practices 2 to 5 years after having graduated from the same science teacher education program. The nine teachers who participated in informal support networks taught the NOS at high/medium levels, while the four non-participating teachers taught the NOS at low levels. The nine high/medium NOS implementation teachers credited the informal support networks for maintaining/heightening their sense of responsibility for teaching NOS and for helping them navigate institutional constraints that impede effective NOS instruction. Several high/medium NOS instruction implementers initially struggled to autonomously frame and resolve the complexities experienced in schools and thus drew from the support networks to engage in more sophisticated forms of teacher decision-making. In contrast, the NOS pedagogical decisions of the four teachers not participating in support networks were governed primarily by the expectations and constraints experienced in their schools. Implications of this study include the need for reconsidering the structure of teacher mentorship programs to ensure they do not promote archaic science teaching practices that are at odds with reform efforts in science education.

Little information exists on work and stress related health of medical doctors in non-EU countries. Filling this knowledge gap is needed to uncover the needs of this target population and to provide information on comparability of health related phenomena such as burnout across countries. This study examined work related characteristics, work-home and home-work interference and burnout among Serbian primary healthcare physicians (PHPs) and compared burnout levels with other medical doctors in EU countries. Data were collected via surveys which contained Maslach Burnout Inventory and other validated instruments measuring work and home related characteristics. The sample consisted of 373 PHPs working in 12 primary healthcare centres. Data were analysed using t-tests and Chi square tests. No gender differences were detected on mean scores of variables among Serbian physicians, who experience high levels of personal accomplishment, workload, job control and social support, medium to high levels of emotional exhaustion, medium levels of depersonalisation and work-home interference, and low levels of home-work interference. There were more women than men who experienced low job control and high depersonalisation. Serbian physicians experienced significantly higher emotional exhaustion and lower depersonalisation than physicians in some other European countries. To diminish excessive workload, the number of physicians working in primary healthcare centres in Serbia should be increased. Considering that differences between countries were detected on all burnout subcomponents, work-related interventions for employees should be country specific. The role of gender needs to be closely examined in future studies as well.

Providing physicians with alerts about potentially harmful drug-drug interactions (DDIs) is only moderately effective due to high alert override rates. To understand high override behavior on DDI alerts, we investigated how physicians respond to DDIs and their behavior patterns and variations. Retrospective system log data analysis and records review (sampling 2% of total overrides). A large tertiary academic hospital. About 560 physicians and their override responses to DDI alerts generated from 1 September to 31 December 2014. Not applicable. DDI alert frequency and override rate. We found significant variation in both the number of alerts and override rates at the levels of physicians, departments and drug-class pairs. Physician-level variations were wider for residents than for faculty staff (number of alerts: t = 254.17, P = 0.011; override rates: t = -4.77, P < 0.0001). Using the number of alerts and their override rate, we classified physicians into four groups: inexperienced incautious users, inexperienced cautious users, experienced cautious users and experienced incautious users. Medical department influenced both alert numbers and override rates. Nearly 90% of the overrides involved only five drug-class combinations, which had a wide range of appropriateness in the chart review. The variations at drug-class levels suggest issues with system design and the DDI rules. Department-level variation may be best addressed at the department level, and the rest of the variation appears related to individual physician responses, suggesting the need for interventions at an individual level.

Blended learning (BL) is the integration of classroom learning with an online environment. The purpose of this study was to determine whether dental students who experienced BL in a preclinical endodontic course demonstrated better manual skills, conceptual knowledge, and learning experience compared to those experiencing traditional learning. All eighty-one students (100 percent) in a preclinical endodontics course agreed to participate and were assigned to either the traditional or BL group. A root canal procedure was used to determine the level of manual skills gained by each group. Pre- and post-intervention quizzes were given to all students to evaluate conceptual knowledge gained, and the students' perspectives on the methods were evaluated with a survey. The BL group scored better than the traditional group on the manual skills exercise at a statistically significant level (p=0.0067). There were no differences in the post-intervention quiz scores between the two groups, and the students' opinions were positive regarding BL. With BL, the students were able to learn and demonstrate dental skills at a high level.

Background: Disease-related stigma is a public health concern steadily gaining global attention. Evidence consistently shows that an individual’s attribution of disease cause can prompt or justify interpersonal stigma. However, few studies have explored causal beliefs about inherited disease and their influence on stigmatising behaviours in low and middle income countries. Design and methods: The study was conducted in 2013, in six communities in Wolaita zone, Southern Ethiopia. A total of 1800 respondents took part in the study, 600 were affected by an inherited disease and 1200 were unaffected neighbours. Two versions of the interviewer-administered survey were created, with measures assessed in parallel on experienced stigma for the affected and enacted stigma for unaffected respondents. Results: Mean levels of enacted stigma reported by unaffected respondents were slightly lower (2.0, SD=0.7) than experienced stigma reported by affected respondents [2.2 (standard deviation=1.1)]. Beliefs that podoconiosis was hereditary were significantly and positively associated with levels of enacted stigma reported by unaffected respondents and experienced stigma reported by affected respondents (P<0.001). There was no association of reported levels of stigma experienced by affected respondents with levels of enacted stigma reported by the neighbouring unaffected respondents. Males consistently reported significantly lower levels of experienced and enacted stigma than females, P<0.0001. Conclusions: If stigma reduction interventions are to be successful, culturally tailored, gender inclusive and innovative health education programs are required, directed at the general community as well as individuals affected by inherited diseases. Significance for public health Disease-related stigma is a public health concern steadily gaining global attention. In this report, we evaluated dual perspectives of stigma, that is, we compared reports of stigma experienced by families affected by a heritable neglected tropical disease with reports of enacted stigma among neighbouring families unaffected by the disease. We found that unaffected neighbours reported enacting less stigma than affected respondents reported experiencing. Levels of enacted and experienced stigma also were influenced by community members’ perceptions of the causes of disease. Enacted and experienced stigma levels also varied by gender (males reported less of each) across sites. Taken together, these findings highlight the need for stigma reduction strategies to involve both affected and unaffected groups if interventions are to be effective. These efforts also should address community members’ baseline explanations of what causes heritable health conditions while considering gender and community context. PMID:27747202

To Love is to Suffer: Older Adults’ Daily Emotional Contagion to Perceived Spousal Suffering

Levy, Becca R.; Kane, Heidi S.

2017-01-01

Abstract Objectives: For older adults coping with a spouse’s chronic condition, greater marital satisfaction may not be entirely protective for psychological health. We examined marital satisfaction and gender as moderators of the association between perceived spousal suffering and daily emotional contagion. Based on empathy-altruism and interdependent self-construal theories, we hypothesized that high marital satisfaction and being female would heighten daily emotional contagion, or within-person associations between perceived spouse suffering and distress to spouse suffering. Method: Forty-five older adults who had a spouse with a musculoskeletal condition completed daily interviews. Participants reported their marital satisfaction once in the laboratory and then daily perceptions of their spouse’s physical suffering and their own distress to spouse suffering via phone at home for 7 days. Results: Consistent with hypotheses, there were significant within-person effects such that highly satisfied wives experienced heightened emotional contagion on days when they perceived higher than average spouse suffering. Unexpectedly, men who were high in marital satisfaction experienced heightened daily distress irrespective of their perceptions of level of spousal suffering. Discussion: Marital satisfaction can increase daily emotional contagion to spousal suffering among older couples dealing with chronic conditions. Wives’ distress may be more dependent on perceiving high levels of partner suffering compared with husbands’ distress. PMID:26420167

The current study examined cardiac denial and psychological predictors (i.e., depression, anxiety) of health outcomes including medical nonadherence and physical health in a sample of 80 adults with congenital heart disease (ACHD). Results indicated that denial of impact was elevated in this patient group compared with reference groups, and denial was negatively associated with depression and anxiety at ps < .01. Results indicated that depression, anxiety, and denial predicted unique variance in medical nonadherence, and gender moderated the relationships between these psychological factors and nonadherence. For depression, men and women showed similar relationships between depression and nonadherence at high levels of depression; however, at low levels of depression (i.e., a more normal mood state), men were less adherent compared with women. For anxiety, men and women did not differ in adherence at low levels of anxiety; however, men experiencing high anxiety were less adherent compared with women experiencing high anxiety. Implications of this study are discussed including the role of gender and denial and the impact of denial functioning to reduce negative affect. Depression was the only significant predictor of physical functioning. Results of this study suggest that psychological interventions aimed at depression and anxiety may function differently across gender to improve patient medical adherence and improve physical functioning in ACHD. © The Author(s) 2015.

To determine the content of integrated curricula, clinical concepts and the underlying basic science concepts need to be made explicit. Preconstructed concept maps are recommended for this purpose. They are mainly constructed by experts. However, concept maps constructed by residents are hypothesized to be less complex, to reveal more tacit basic science concepts and these basic science concepts are expected to be used for the organization of the maps. These hypotheses are derived from studies about knowledge development of individuals. However, integrated curricula require a high degree of cooperation between clinicians and basic scientists. This study examined whether there are consistent variations regarding the articulation of integration when groups of experienced clinicians and basic scientists and groups of residents and basic scientists-in-training construct concept maps. Seven groups of three clinicians and basic scientists on experienced level and seven such groups on resident level constructed concept maps illuminating clinical problems. They were guided by instructions that focused them on articulation of integration. The concept maps were analysed by features that described integration. Descriptive statistics showed consistent variations between the two expertise levels. The concept maps of the resident groups exceeded those of the experienced groups in articulated integration. First, they used significantly more links between clinical and basic science concepts. Second, these links connected basic science concepts with a greater variety of clinical concepts than the experienced groups. Third, although residents did not use significantly more basic science concepts, they used them significantly more frequent to organize the clinical concepts. The conclusion was drawn that not all hypotheses could be confirmed and that the resident concept maps were more elaborate than expected. This article discusses the implications for the role that residents and basic scientists-in-training might play in the construction of preconstructed concept maps and the development of integrated curricula.

Antecedents of Psychological Contract Breach: The Role of Job Demands, Job Resources, and Affect

While it has been shown that psychological contract breach leads to detrimental outcomes, relatively little is known about factors leading to perceptions of breach. We examine if job demands and resources predict breach perceptions. We argue that perceiving high demands elicits negative affect, while perceiving high resources stimulates positive affect. Positive and negative affect, in turn, influence the likelihood that psychological contract breaches are perceived. We conducted two experience sampling studies to test our hypotheses: the first using daily surveys in a sample of volunteers, the second using weekly surveys in samples of volunteers and paid employees. Our results confirm that job demands and resources are associated with negative and positive affect respectively. Mediation analyses revealed that people who experienced high job resources were less likely to report psychological contract breach, because they experienced high levels of positive affect. The mediating role of negative affect was more complex, as it increased the likelihood to perceive psychological contract breach, but only in the short-term. PMID:27171275

This study investigated the effect of nursing experience on attention allocation and task performance during surgery. The prevention of cases of retained foreign bodies after surgery typically depends on scrub nurses, who are responsible for performing multiple tasks that impose heavy demands on the nurses' cognitive resources. However, the relationship between the level of experiences and attention allocation strategies has not been extensively studied. Eye movement data were collected from 10 novice and 10 experienced scrub nurses in the operating theater for caesarean section surgeries. Visual scanning data, analyzed by dividing the workstation into four main areas and the surgery into four stages, were compared to the optimum expected value estimated by SEEV (Salience, Effort, Expectancy, and Value) model. Both experienced and novice nurses showed significant correlations to the optimal percentage dwell time values, and significant differences were found in attention allocation optimality between experienced and novice nurses, with experienced nurses adhering significantly more to the optimal in the stages of high workload. Experienced nurses spent less time on the final count and encountered fewer interruptions during the count than novices indicating better performance in task management, whereas novice nurses switched attention between areas of interest more than experienced nurses. The results provide empirical evidence of a relationship between the application of optimal visual attention management strategies and performance, opening up possibilities to the development of visual attention and interruption training for better performance.

2013-01-01

This brief article looks at the intersection of climate, land cover/land use, and population trends in the world's most food insecure country, Ethiopia. As a result of warming in the Indian and Western Pacific oceans, Ethiopia has experienced substantial drying over the past 20 years. We intersect the spatial pattern of this drying with high resolution climatologies, maps of agricultural expansion, population data, and socioeconomic livelihoods information to suggest that the coincidence of drying and agricultural expansion in south-central Ethiopia is likely adversely affecting a densely populated region with high levels of poverty and low wage levels.

Park, Jin Hee; Lee, Eun Nam; Kong, Kyung Ran; Jang, Moon Jung

2017-11-01

This secondary analysis examined the mediating effect of hardiness between stress and impact level in ED nurses who experienced a violent event. This correlational study was conducted from June to August 2014. We used the visual analog scale to measure stress level, the Impact of Event Scale-Revised to measure impact level after the violent event, and the Dispositional Resilience Scale to measure hardiness. We then analyzed mediating effects with the Sobel test. Data were collected in 31 emergency medical centers located in B city in Korea. Data from 321 ED nurses who experienced a violent event were analyzed. Most nurses (91.9%) were women, with a mean age of 28.73 years. The main outcome measure was the mediating effect of hardiness between stress and impact level after ED nurses experienced violence. We found that both violence-related stress (B = 0.22, P < .001) and hardiness (B = -0.33, P = .037) were significant predictors of impact level from a violent event. Based on results of a Sobel test, hardiness partially mediated the relationship between violence-related stress and impact level from a violent event (Z = 2.03, P = .044). Hardiness had an effect on reducing the impact level of ED nurses who had experienced a violent event and had a mediating role in mitigating their stress. Therefore, we recommend the development of an intervention program that emphasizes the improvement of hardiness in ED nurses. Copyright © 2017 Emergency Nurses Association. Published by Elsevier Inc.

Physicians who are caring for patients with implantable cardioverter-defibrillators (ICDs) are regularly confronted with questions concerning daily activities. This study evaluates the habits of ICD patients with respect to sports activities, stays at high-altitude, and driving patterns. A survey was performed in 387 patients with ICDs who were followed at two hospitals in Switzerland. The special-designed questionnaire addressed lifestyle practices concerning sports activity, high-altitude visits, and driving motor vehicles. Fifty-nine percent of ICD patients participated in some kind of sports activity; an ICD shock was experienced in 14% of these patients. Fifty-six percent of the patients reported a stay at high altitudes at least 2,000 m above the sea level; 11% of them stayed regularly above 2,500 m; 4% of these patients experienced an ICD shock during high altitude stay. Seventy-nine percent of the patients drove a motor vehicle; 2% of them experienced an ICD shock during driving, but none of them reported loss of consciousness or a traffic accident. It is accepted that ICD patients disqualify for competitive sports. However, the patients may be encouraged to continue leisure-time physical activities at low-to-moderate intensity. Staying at high altitudes and driving motor vehicles are very rarely associated with ICD shocks. Therefore, these activities that are likely to contribute to a better quality of life should not be discouraged in most ICD recipients in the absence of other medical reasons.

E-cigarettes generate high levels of aldehydes only in 'dry puff' conditions.

PubMed

Farsalinos, Konstantinos E; Voudris, Vassilis; Poulas, Konstantinos

2015-08-01

Aldehydes are emitted by electronic cigarettes due to thermal decomposition of liquid components. Although elevated levels have been reported with new-generation high-power devices, it is unclear whether they are relevant to true exposure of users (vapers) because overheating produces an unpleasant taste, called a dry puff, which vapers learn to avoid. The aim was to evaluate aldehyde emissions at different power levels associated with normal and dry puff conditions. Two customizable atomizers were prepared so that one (A1) had a double wick, resulting in high liquid supply and lower chance of overheating at high power levels, while the other (A2) was a conventional setup (single wick). Experienced vapers took 4-s puffs at 6.5 watts (W), 7.5 W, 9 W and 10 W power levels with both atomizers and were asked to report whether dry puffs were generated. The atomizers were then attached to a smoking machine and aerosol was trapped. Clinic office and analytical chemistry laboratory in Greece. Seven experienced vapers. Aldehyde levels were measured in the aerosol. All vapers identified dry puff conditions at 9 W and 10 W with A2. A1 did not lead to dry puffs at any power level. Minimal amounts of aldehydes per 10 puffs were found at all power levels with A1 (up to 11.3 µg for formaldehyde, 4.5 µg for acetaldehyde and 1.0 µg for acrolein) and at 6.5 W and 7.5 W with A2 (up to 3.7 µg for formaldehyde, 0.8 µg for acetaldehyde and 1.3 µg for acrolein). The levels were increased by 30 to 250 times in dry puff conditions (up to 344.6 µg for formaldehyde, 206.3 µg for acetaldehyde and 210.4 µg for acrolein, P < 0.001), while acetone was detected only in dry puff conditions (up to 22.5 µg). Electronic cigarettes produce high levels of aldehyde only in dry puff conditions, in which the liquid overheats, causing a strong unpleasant taste that e-cigarette users detect and avoid. Under normal vaping conditions aldehyde emissions are minimal, even in new-generation high-power e-cigarettes. © 2015 Society for the Study of Addiction.

Drinking Water Salinity and Raised Blood Pressure: Evidence from a Cohort Study in Coastal Bangladesh

Background: Millions of coastal inhabitants in Southeast Asia have been experiencing increasing sodium concentrations in their drinking-water sources, likely partially due to climate change. High (dietary) sodium intake has convincingly been proven to increase risk of hypertension; it remains unknown, however, whether consumption of sodium in drinking water could have similar effects on health. Objectives: We present the results of a cohort study in which we assessed the effects of drinking-water sodium (DWS) on blood pressure (BP) in coastal populations in Bangladesh. Methods: DWS, BP, and information on personal, lifestyle, and environmental factors were collected from 581 participants. We used generalized linear latent and mixed methods to model the effects of DWS on BP and assessed the associations between changes in DWS and BP when participants experienced changing sodium levels in water, switched from “conventional” ponds or tube wells to alternatives [managed aquifer recharge (MAR) and rainwater harvesting] that aimed to reduce sodium levels, or experienced a combination of these changes. Results: DWS concentrations were highly associated with BP after adjustments for confounding factors. Furthermore, for each 100mg/L reduction in sodium in drinking water, systolic/diastolic BP was lower on average by 0.95/0.57mmHg, and odds of hypertension were lower by 14%. However, MAR did not consistently lower sodium levels. Conclusions: DWS is an important source of daily sodium intake in salinity-affected areas and is a risk factor for hypertension. Considering the likely increasing trend in coastal salinity, prompt action is required. Because MAR showed variable effects, alternative technologies for providing reliable, safe, low-sodium fresh water should be developed alongside improvements in MAR and evaluated in “real-life” salinity-affected settings. https://doi.org/10.1289/EHP659 PMID:28599268

Wallwork, Tracy L; Hides, Julie A; Stanton, Warren R

2007-10-01

Within-session intrarater and interrater reliability study. To establish the intrarater and interrater reliability of thickness measurements of the multifidus muscle in a parasagittal plane, conducted by an experienced ultrasound operator and a novice assessor. There is considerable evidence for the important role of the multifidus muscle in segmental stabilization of the lumbar spine. The cross-sectional area of the multifidus muscle has been assessed in healthy subjects and patients with low back pain using real-time ultrasound imaging. However, few studies have measured the thickness of the multifidus muscle using a parasagittal view. The thickness of the multifidus muscle was measured at rest, using real-time ultrasound imaging, in 10 subjects without a history of low back pain, at the levels of the L2-3 and L4-5 zygapophyseal joints. The measure was carried out 3 times at each level by 2 assessors (1 experienced, 1 novice). Intrarater (model 3) and interrater (model 2) reliability was assessed by calculation of an F statistic (analysis of variance), the intraclass correlation coefficient (ICC), and the standard error of measurement (SEM). On the basis of an average of 3 trials, the 2 operators showed very high interrater agreement on the measurement of thicknesses at the L2-3 level (ICC2,3 = 0.96; 95% CI: 0.84 to 0.99) and the L4-5 vertebral level (ICC2,3 = 0.97; 95% CI: 0.87 to 0.99), with no systematic differences in muscle size across operators (P > .05). Interrater reliability was relatively lower for the L2-3 level (ICC2,1 = 0.85; 95% CI: 0.51 to 0.96) than the L4-5 level (ICC2,1 = 0.87; 95% CI: 0.52 to 0.97) when a single trial per rater was used, but these values still indicated a high level of agreement. In addition, the novice and experienced operator produced reliable intrarater measurements at L2-3 (ICC3,1 = 0.89; 95% CI: 0.72 to 0.97 and 0.94; 95% CI: 0.86 to 0.99) and at L4-5 (ICC3,1 = 0.88; 95% CI: 0.68 to 0.97 and 0.95; 95% CI: 0.86 to 0.99), with no systematic differences in muscle size across trials (P > .05). The consistently low SEM values also indicate low measurement error. A novice and an experienced assessor were both able to reliably perform this measure at rest for 2 vertebral levels using real-time ultrasound imaging. An average of 3 trials produced higher interrater reliability scores, though using a single trial per rater was also reliable.

Burnout in the working population: relations to psychosocial work factors.

Lindblom, Karin M; Linton, Steven J; Fedeli, Cecilia; Bryngelsson, Ing-Liss

2006-01-01

This study investigated levels of burnout in the general population irrespective of occupation and relations between burnout and psychosocial work factors. A cross-sectional survey featuring sleep problems, psychological distress, burnout (Maslach Burnout Inventory-General Survey), and psychosocial factors at work, was mailed to a random sample of 3,000 participants, aged 20-60. Response rate was 61%. A high level (18%), a low level (19%), and an intermediate group (63%) for burnout were constructed. The high level group was associated with those who were > 50 years old, women, those experiencing psychological distress, and those with a poor psychosocial work climate. The analyses on variables significant in previous analyses showed that the high level group was strongly related to high demands, low control, lack of social support, and disagreeing about values at the workplace even when accounting for age, gender, and psychological distress. We conclude that psychosocial work factors are important in association to burnout regardless of occupation.

An examination of body tracing among women with high body dissatisfaction.

Williams, Gail A; Hudson, Danae L; Whisenhunt, Brooke L; Crowther, Janis H

2014-09-01

Within eating disorder treatment programs, a body tracing activity is often used to address body dissatisfaction and overestimation of body size; however, the effects of this activity have never been empirically evaluated. This research examined the effects of body tracing on body dissatisfaction and mood among 56 female participants assigned to either a body tracing or control group. Scores were collected on trait body dissatisfaction and a series of Visual Analogue Scales (VAS). Results showed that trait body dissatisfaction moderated the relationship between group and levels of state appearance dissatisfaction and anxiety. These results suggest that individuals experiencing higher levels of trait body dissatisfaction demonstrated greater state body dissatisfaction following participation in the body tracing activity. Individuals with lower trait body dissatisfaction experienced greater anxiety after drawing a human body. These findings have potential implications for the use of this strategy in the treatment of eating disorder patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

Perceived social pressure not to experience negative emotion is linked to selective attention for negative information.

PubMed

Bastian, Brock; Pe, Madeline Lee; Kuppens, Peter

2017-02-01

Social norms and values may be important predictors of how people engage with and regulate their negative emotional experiences. Previous research has shown that social expectancies (the perceived social pressure not to feel negative emotion (NE)) exacerbate feelings of sadness. In the current research, we examined whether social expectancies may be linked to how people process emotional information. Using a modified classical flanker task involving emotional rather than non-emotional stimuli, we found that, for those who experienced low levels of NE, social expectancies were linked to the selective avoidance of negative emotional information. Those who experienced high levels of NE did not show a selective avoidance of negative emotional information. The findings suggest that, for people who experience many NEs, social expectancies may lead to discrepancies between how they think they ought to feel and the kind of emotional information they pay attention to.

The capability of static and dynamic features to distinguish competent from genuinely expert practitioners in pediatric diagnosis.

Loveday, Thomas; Wiggins, Mark W; Searle, Ben J; Festa, Marino; Schell, David

2013-02-01

The authors describe the development of a new, more objective method of distinguishing experienced competent nonexpert from expert practitioners within pediatric intensive care. Expert performance involves the acquisition and use of refined feature-event associations (cues) in the operational environment. Competent non-experts, although experienced, possess rudimentary cue associations in memory. Thus, they cannot respond as efficiently or as reliably as their expert counterparts, particularly when key diagnostic information is unavailable, such as that provided by dynamic cues. This study involved the application of four distinct tasks in which the use of relevant cues could be expected to increase both the accuracy and the efficiency of diagnostic performance. These tasks included both static and dynamic stimuli that were varied systematically. A total of 50 experienced pediatric intensive staff took part in the study. The sample clustered into two levels across the tasks: Participants who performed at a consistently high level throughout the four tasks were labeled experts, and participants who performed at a lower level throughout the tasks were labeled competent nonexperts. The groups differed in their responses to the diagnostic scenarios presented in two of the tasks and their ability to maintain performance in the absence of dynamic features. Experienced pediatricians can be decomposed into two groups on the basis of their capacity to acquire and use cues; these groups differ in their diagnostic accuracy and in their ability to maintain performance in the absence of dynamic features. The tasks may be used to identify practitioners who are failing to acquire expertise at a rate consistent with their experience, position, or training. This information may be used to guide targeted training efforts.

Children and mothers who have suffered domestic or neighbourhood violence constitute a high risk group, although it has not been clear whether their mental health needs are specifically related to the type of violence. This paper reports on the prevalence of mental health problems in homeless parents and children who have experienced domestic and neighbourhood violence and their access to social support networks. Three groups of families who had become homeless were compared: those experiencing domestic violence (48 with 75 children), victims of neighbourhood violence (14 with 29 children), and those who became homeless for other reasons (31 with 54 children). Mothers completed a service use semi-structured interview, the Strengths and Difficulties Questionnaire, the General Health Questionnaire, the Family Support Scales, and the SF-36 Health Status Questionnaire. Levels of psychiatric morbidity were high in the group experiencing domestic violence (35.7% in children and 21.9% in mothers) and higher still in those who were victims of neighbourhood violence (52.2% in children and 50% in mothers). Levels of social support were found to be an important factor, particularly in relation to professional support and support from other family members, as they predicted both child and maternal psychopathology. Mental health interventions for victims of domestic and neighbourhood violence should be integrated with community programmes of social reintegration. Mental health professionals should work in close collaboration with Housing Departments, Social Services, Education and the Police.

Regionally aggregated bulk milk somatic cell count (BMSCC) data from around the world shows a repeatable cyclicity, with the highest levels experienced during warm, humid seasons. No studies have evaluated this seasonal phenomenon at the herd level. The objectives of this study were to define summer seasonality in BMSCC on an individual herd basis, and subsequently to describe the characteristics and dynamics of herds with increased BMSCC in the summer. The data used for this analysis were from all dairy farms in Ontario, Canada, between January 2000 and December 2011 (n≈4,000 to 6,000 herds/yr). Bulk milk data were obtained from the milk marketing board and consisted of bulk milk production, components (fat, protein, lactose, other solids), and quality (BMSCC, bacterial count, inhibitor presence, freezing point), total milk quota of the farm, and milk quota and incentive fill percentage. A time-series linear mixed model, with random slopes and intercepts, was constructed using sine and cosine terms as predictors to describe seasonality, with herd as a random effect. For each herd, seasonality was described with reference to 1 cosine function of variable amplitude and phase shift. The predicted months of maximal and minimal BMSCC were then calculated. Herds were assigned as low, medium, and high summer increase (LSI, MSI, and HSI, respectively) based on percentiles of amplitude in BMSCC change for each of the 4 seasons. Using these seasonality classifications, 2 transitional repeated measures logistic regression models were built to assess the characteristics of MSI and HSI herds, using LSI herds as controls. Based on the analyses performed, a history of summer BMSCC increases increased the odds of experiencing a subsequent increase. As herd size decreased, the odds of experiencing HSI to MSI in BMSCC increased. Herds with more variability in daily BMSCC were at higher odds of experiencing MSI and HSI in BMSCC, as were herds with lower annual mean BMSCC. Finally, a negative association was noted between filling herd production targets and experiencing MSI to HSI in BMSCC. These findings provide farm advisors direction for predicting herds likely to experience increases in SCC over the summer, allowing them to proactively focus udder health prevention strategies before the high-risk summer period.

Schools are one of the strongest socializing forces in the U.S. and wield considerable influence over individuals' social and economic trajectories. Our study investigates how school-level racial composition, measured by the percentage non-Hispanic white students in a school, affects depressive and somatic symptoms among a representative sample of U.S. adolescents, and whether the association differs by race/ethnicity. We analyzed Wave I data from the US National Longitudinal Study of Adolescent Health, resulting in a sample size of 18,419 students attending 132 junior and senior high schools in 1994/5. After controlling for individual and school characteristics, our multilevel analyses indicated that with increasing percentages of white students at their school, black students experienced more depressive symptoms and a higher risk of reporting high levels of somatic symptoms. After including students' perceptions of discrimination and school attachment, the interaction between black student race and school-level racial composition was no longer significant for either outcome. Our findings suggest that attending predominantly-minority schools may buffer black students from discrimination and increase their school attachment, which may reduce their risk of experiencing depressive and somatic symptoms.

To investigate the incidence of workplace violence involving nurses and to identify related risk factors in a high-quality Chinese teaching hospital. A cross-sectional study design was used. The final sample comprised responses from 1831 registered nurses collected with a whole-hospital survey from June 1 to June 15, 2016. The demographic characteristics of the nurses who had experienced any form of violence were collected, and logistic regression analysis was applied to evaluate the risk factors for nurses related to workplace violence. Out of the total number of nurses surveyed, 904 (49.4%) nurses reported having experienced any type of violence in the past year. The frequencies of exposure to physical and non-physical violence were 6.3% (116) and 49.0% (897), respectively. All the incidence rates of violence were lower than those of other studies based on regional hospitals in China and were at the same level found in developed countries and districts. Binary logistic regression analysis revealed that nurses at levels 2 to 4 and female nurses in clinical departments were the most vulnerable to non-physical violence. For physical violence, the two independent risk factors were working in an emergency department and having 6-10 years of work experience. Workplace violence directly threatens nurses from high-quality Chinese teaching hospitals. However, the incidence of WPV against nurses in this teaching hospital was better than that in regional hospitals. This study also provides reference material to identify areas where nurses encounter relatively high levels of workplace violence in high-quality Chinese teaching hospitals.

According to the levels-of-processing hypothesis, transitions from unconscious to conscious perception may depend on stimulus processing level, with more gradual changes for low-level stimuli and more dichotomous changes for high-level stimuli. In an event-related fMRI study we explored this hypothesis using a visual backward masking procedure. Task requirements manipulated level of processing. Participants reported the magnitude of the target digit in the high-level task, its color in the low-level task, and rated subjective visibility of stimuli using the Perceptual Awareness Scale. Intermediate stimulus visibility was reported more frequently in the low-level task, confirming prior behavioral results. Visible targets recruited insulo-fronto-parietal regions in both tasks. Task effects were observed in visual areas, with higher activity in the low-level task across all visibility levels. Thus, the influence of level of processing on conscious perception may be mediated by attentional modulation of activity in regions representing features of consciously experienced stimuli.

Park, Jinhee; Yun, Chul; Kang, Seungcheol

2016-01-01

Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC) has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training. Among 361 young male aviators on active flight duty with experience in high performance aircrafts for at least 2 years, 350 had full data available and were reviewed in this study. We divided the aviators into the G-LOC group and the non-G-LOC group according to their human centrifuge training results. We then compared their basic characteristics, body composition, physical fitness level, and pulmonary function. Twenty nine aviators (8.3%) who experienced G-LOC during human centrifuge training in their first trials were classified into the G-LOC group. There was no difference in physical condition of aviators between the two groups. Young aviators with experience in G-LOC showed no difference in physical condition such as muscle mass, strength, and general endurance from the aviators with no such experience. Although more studies are needed, physical condition does not seem to be a significant determinant of G-LOC among the experienced aviators.

In order to meet the future challenges posed by ageing populations, new technology, telemedicine and a more personalized healthcare system are needed. Earlier research has shown mobile radiography services to be highly beneficial for nursing home residents in addition to being cost-effective. Despite the benefits, mobile radiography services are uncommon in Europe and Norway. The purpose of this study was to explore success criteria and barriers in the process of implementing mobile radiography services, from the point of view of the hospital and municipal managers. Eleven semi-structured interviews were conducted with managers from five hospitals and six municipalities in Norway where mobile radiography services had been implemented. Core issues in the interview guide were barriers and facilitators in the different phases of implementation. The framework method for thematic analysis was used for analysing the data inductively in a research team. Five main categories were developed through the success criteria and barriers experienced by the participants: national health policy, regional and municipal policy and conditions, inter-organizational implementation projects, experienced outcome, and professional skills and personal characteristics. The categories were allocated into three higher-order classifications: macro, meso and micro levels. The main barriers experienced by the managers were financial, procedural and structural. In particular, the reimbursement system, lack of management across healthcare levels and the lack of compatible information systems acted as barriers. The main facilitators were external funding, enthusiastic individuals in the organizations and good collaboration between hospitals and municipalities. The managers experienced financial, structural and procedural barriers. The main success criteria in the process were external funding, and the support and engagement from the individuals in the organizations. This commitment was mainly facilitated by the intuitive appeal of mobile radiography. Changes in healthcare management and in the financial system might facilitate services across healthcare levels. In addition, compatible information systems across healthcare levels are needed in order to facilitate the use of new technology and mobile services.

Association between stigma, depression and quality of life of people living with HIV/AIDS (PLHA) in South India – a community based cross sectional study

PubMed Central

2012-01-01

Background India has around 2.27 million adults living with HIV/AIDS who face several challenges in the medical management of their disease. Stigma, discrimination and psychosocial issues are prevalent. The objective of the study was to determine the prevalence of severe stigma and to study the association between this, depression and the quality of life (QOL) of people living with HIV/AIDS (PLHA) in Tamil Nadu. Methods This was a community based cross sectional study carried out in seven districts of Tamil Nadu, India, among 400 PLHA in the year 2009. The following scales were used for stigma, depression and quality of life, Berger scale, Major Depression Inventory (MDI) scale and the WHO BREF scale. Both Stigma and QOL were classified as none, moderate or severe/poor based on the tertile cut off values of the scale scores. Depression was classified as none, mild, moderate and severe. Logistic regression analyses were performed to study the risk factors. Results Twenty seven per cent of PLHA had experienced severe forms of stigma. These were severe forms of personalized stigma (28.8%), negative self-image (30.3%), perceived public attitude (18.2%) and disclosure concerns (26%). PLHA experiencing severe depression were 12% and those experiencing poor quality of life were 34%. Poor QOL reported in the physical, psychological, social and environmental domains was 42.5%, 40%, 51.2% and 34% respectively. PLHA who had severe personalized stigma and negative self-image had 3.4 (1.6-7.0) and 2.1 (1.0-4.1) times higher risk of severe depression respectively (p < .001). PLHA who had severe depression had experienced 2.7(1.1-7.7) times significantly poorer QOL. Conclusions Severe forms of stigma were equivalently prevalent among all the categories of PLHA. However, PLHA who had experienced severe depression had only developed poor QOL. A high level of social support was associated with a high level of QOL. PMID:22720691

2005-11-01

The aim of this study was to examine yo-yo intermittent recovery test (Yo-Yo test) and 12-minute run test (12MRT) performances in experienced soccer referees of different competitive levels. Three groups (n = 14 each) of experienced Italian soccer referees officiating in the first (series AB, top-level), third (series C, medium-level), and fourth (series D, low-level) division, were randomly submitted to the 12MRT and the Yo-Yo test during 2 testing sessions, 48-hours apart. 12MRT performances were 3,000 +/- 112 m; 2,894 +/- 99 m; and 2,896 +/- 171 m for top-level, medium-level and low-level referees, respectively (p > 0.05). In the Yo-Yo test, the top-level, medium-level, and low-level referees covered 1,874 +/- 431 m; 1,360 +/- 172 m; and 1,272 +/- 215 m, respectively. The test performances of top-level referees in the Yo-Yo test was significantly different from those scored by medium-level and low-level referees (p < 0.05). After the Yo-Yo test, blood lactate concentrations (BLC) were higher in the medium-level and low-level referees compared with the top-level referees (p < 0.05). The results of the present study show that the Yo-Yo test and not the 12MRT can discriminate endurance performance in experienced elite level soccer referees. With respect to its discriminative and match performance validity, the Yo-Yo test may be considered a relevant field test to assess endurance preparedness for experienced soccer referees and a useful tool in talent selection.

Social workers are considered a professional group at high risk of burnout. Noticing the insufficient human resource management and understaffed social work centers, Iranian social workers are faced with a considerable level of physical and mental stress, which can lead to burnout. A national study on 390 social workers was conducted. Among social workers, 10.9% had experienced burnout and 17.4% are at risk of developing burnout. Social workers scored higher in burnout if they were dissatisfied with their income, had experienced violence, or had lower self-esteem. Findings are discussed with regard to Iranian context and recommendations for authorities of Iranian state welfare organizations are made. PMID:23777730

2003-12-01

This study examined whether positive events mitigated the relation between negative events and maladjustment in samples of children and adolescents experiencing family transitions. The study examined this relation in two samples, used multiple reporters of maladjustment, and employed "tailor-made" checklists to measure events. The first sample included 86 stepfamilies with adolescents 10 to 17 years of age. The second sample included 171 divorced families with children 8 to 15 years of age. Evidence that positive events are protective for children and adolescents experiencing high levels of negative events was found across the 2 samples and across mother and child report of adjustment. These findings have implications for theory and intervention development.

2018-02-01

The study was done at Semarang, Central Java. The aims of the study are: (a) to know the variation in the level of community capacity in dealing with landslide hazards in the southern of Semarang city; (B) to know the factors that affect the capacity of communities in facing the hazards of landslides. This research was conducted by the sample method with a sample of 198 people, taken by purposive sampling. Samples taken are people living in areas that have experienced landslide or in areas that are expected to be vulnerable to landslides. The variables used in this research are (1) regulatory and institutional capacity in the prevention of landslide disaster, (2) early warning system in community, (3) education of disaster skill training, (4) mitigation to reduce basic risk factor, and (5) Preparedness on all fronts. Data were collected with questioner and interviews. Data analysis was performed by percentage descriptions, and map overlay analysis using ArcGIS release 10.3 technology. The result of the research shows that there are 5 variations of society's capacity level in facing the landslide hazard in southern Semarang city, that is the very high capacity of society as much as 4,35 % of the people that researched, the high community capacity is 7,25 % of the people that researched, the medium community capacity is 30.43 %. of the people that researched, low community capacity as much as 36.23 % of the people that researched and very low community capacity as much as 21.74% of the people that researched. Based on the result of overlay map of landslide threat in southern Semarang City with map about variation of community capacity level in facing landslide hazard indicate that community capacity with very high criterion and high occupancy area of threat of landslide with high and medium criterion which have been experienced landslide. While the capacity of the community with the criteria of medium, low and very low occupies the threat of landslide areas with high, medium, low and very low criteria that have never experienced landslide. The existence of the experience of a landslide disaster is one of the factors that encourage the community to increase the community capacity in facing the landslide.

Background The nature and structure of the school environment has the potential to shape children's health and well being. Few studies have explored the importance of school-level factors in explaining a child's likelihood of experiencing violence from school staff, particularly in low-resource settings such as Uganda. Methods To quantify to what extent a student's risk of violence is determined by school-level factors we fitted multilevel logistic regression models to investigate associations and present between-school variance partition coefficients. School structural factors, academic and supportive environment are explored. Results 53% of students reported physical violence from staff. Only 6% of variation in students' experience of violence was due to differences between schools and half the variation was explained by the school-level factors modelled. Schools with a higher proportion of girls are associated with increased odds of physical violence from staff. Students in schools with a high level of student perceptions of school connectedness have a 36% reduced odds of experiencing physical violence from staff, but no other school-level factor was significantly associated. Conclusion Our findings suggest that physical violence by school staff is widespread across different types of schools in this setting, but interventions that improve students' school connectedness should be considered.

Chen, Yu-Meng; Fang, Jin-Bo

2016-02-01

Nurse burnout and low job satisfaction are main reasons that cause nurses to leave their current position. Improving the nursing work environment may reduce the severity of job burnout and of job dissatisfaction and thus decrease the turnover intention of nursing staff. The aim of this study was to explore the correlation between the nursing work environment and the outcome variables of burnout, job satisfaction, and turnover intention in the western region of Mainland China. This is a cross-sectional descriptive study. Survey data were collected between February and December 2012 from 1,112 clinical nurses working at 83 medical, surgical, and intensive care units in 20 hospitals across the western region of Mainland China. Multistage sampling was conducted on some of the participants. The research instruments that were used included the Practice Environment Scale of the Nursing Work Index, Maslach Burnout Inventory, Nurse Job Satisfaction Scale, and the self-developed basic information and turnover intention questionnaire. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 19.0. The level of statistical significance was set at p<.05. Among the five dimensions of the nursing work environment, collegial nurse-physician relations earned the most favorable mean scores (3.57±0.68; total=4 points), whereas adequacy of staffing and resources earned the lowest (3.21±0.82). Over half of the participants (58.4%) reported experiencing a high level of emotional exhaustion (EE) burnout, 45.2% reported experiencing a high level of depersonalization (DP) burnout, and 24.6% reported experiencing a high level of personal accomplishment (PA) burnout. About 59% of the participants were satisfied with their work and 3.8% reported intention to leave. Participants in self-reported "favorable" work environments were less likely to report high burnout, less likely to report intention to leave, and more likely to report job satisfaction than their peers in self-reported "poor" work environments. The odds ratio (OR) values were 0.64 (EE), 0.66 (DP), 0.57 (PA), 0.19, and 2.26. The results of the present study support that the nursing work environment affects nurse burnout, job satisfaction, and turnover intention. Therefore, nursing managers should work to improve nursing work environments in order to reduce the turnover intent among their nursing staff.

Teen Dating Violence (Physical and Sexual) Among US High School Students: Findings From the 2013 National Youth Risk Behavior Survey.

National estimates of teen dating violence (TDV) reveal high rates of victimization among high school populations. The Centers for Disease Control and Prevention's national Youth Risk Behavior Survey has provided often-cited estimates of physical TDV since 1999. In 2013, revisions were made to the physical TDV question to capture more serious forms of physical TDV and to screen out students who did not date. An additional question was added to assess sexual TDV. To describe the content of new physical and sexual TDV victimization questions first administered in the 2013 national Youth Risk Behavior Survey, to share data on the prevalence and frequency of TDV (including the first-ever published overall "both physical and sexual TDV" and "any TDV" national estimates using these new questions), and to assess associations of TDV experience with health-risk behaviors. Secondary data analysis of a cross-sectional survey of 9900 students who dated, from a nationally representative sample of US high school students, using the 2013 national Youth Risk Behavior Survey. Two survey questions separately assessed physical and sexual TDV; this analysis combined them to create a 4-level TDV measure and a 2-level TDV measure. The 4-level TDV measure includes "physical TDV only," "sexual TDV only," "both physical and sexual TDV," and "none." The 2-level TDV measure includes "any TDV" (either or both physical and sexual TDV) and "none." Sex-stratified bivariate and multivariable analyses assessed associations between TDV and health-risk behaviors. In 2013, among students who dated, 20.9% of female students (95% CI, 19.0%-23.0%) and 10.4% of male students (95% CI, 9.0%-11.7%) experienced some form of TDV during the 12 months before the survey. Female students had a higher prevalence than male students of physical TDV only, sexual TDV only, both physical and sexual TDV, and any TDV. All health-risk behaviors were most prevalent among students who experienced both forms of TDV and were least prevalent among students who experienced none (all P < .001). The 2013 TDV questions allowed for new prevalence estimates of TDV to be established that represent a more complete measure of TDV and are useful in determining associations with health-risk behaviors among youth exposed to these different forms of TDV.

The impact of acculturation and religious identification on perceived discrimination for Arab/Middle Eastern Americans.

PubMed

Awad, Germine H

2010-01-01

The aim of the current study was to determine the impact of acculturation, ethnic identity, and religious affiliation on perceived discrimination for persons of Arab and Middle Eastern descent. Two aspects of acculturation (ethnic society immersion and dominant society immersion), religious affiliation, and ethnic identity were measured using a final sample of 177 individuals of Arab or Middle Eastern descent. Results indicated that Arab/Middle Eastern Americans who reported lower levels of dominant society immersion tended to report higher levels of discrimination. Furthermore, Muslims reported a higher level of discrimination than Christians but this finding was moderated by level of acculturation. Specifically, Muslims who reported a high level of dominant society immersion experienced the most discrimination, whereas Christians who reported a high level of dominant society immersion reported less discrimination. Study implications are discussed. (c) 2009 APA, all rights reserved.

Worry about terror among young adults living in ongoing security uncertainty.

Peleg, Ora; Mass-Friedman, Michelle

2013-01-01

The aim of the current study was to investigate worry about terror as a mediating variable, with the exogenous variables being media viewing, differentiation of self, and trait anxiety, and the endogenous variables being somatic symptoms and perceptions of security-related stress. Participants were divided into two groups by age/academic level: 248 high school students and 191 university students. A pathway correlation model was used to investigate worry about terror as a mediating variable. The central finding was that worry about terror was a significant mediating variable in the relationship between the extent of media viewing following terror events and the level of perception of security-related stress. That is, young people who said they worried a lot reported a high level of stress relating to the terror events they saw covered in the media. In addition, trait anxiety was found to have an effect on stress perception only via the level of worry about terror. This means that high levels of stress are not experienced by all highly trait-anxious people, but only by those who suffer from higher levels of worry about terror.

Operator adaptation to changes in system reliability under adaptable automation.

Chavaillaz, Alain; Sauer, Juergen

This experiment examined how operators coped with a change in system reliability between training and testing. Forty participants were trained for 3 h on a complex process control simulation modelling six levels of automation (LOA). In training, participants either experienced a high- (100%) or low-reliability system (50%). The impact of training experience on operator behaviour was examined during a 2.5 h testing session, in which participants either experienced a high- (100%) or low-reliability system (60%). The results showed that most operators did not often switch between LOA. Most chose an LOA that relieved them of most tasks but maintained their decision authority. Training experience did not have a strong impact on the outcome measures (e.g. performance, complacency). Low system reliability led to decreased performance and self-confidence. Furthermore, complacency was observed under high system reliability. Overall, the findings suggest benefits of adaptable automation because it accommodates different operator preferences for LOA. Practitioner Summary: The present research shows that operators can adapt to changes in system reliability between training and testing sessions. Furthermore, it provides evidence that each operator has his/her preferred automation level. Since this preference varies strongly between operators, adaptable automation seems to be suitable to accommodate these large differences.

Is fun for everyone? Personality differences in healthcare providers' attitudes toward fun.

Karl, Katherine A; Peluchette, Joy V; Harland, Lynn

2007-01-01

This study examines the role of personality (the Big Five dimensions) in attitudes towards fun and levels of experienced fun in the healthcare environment. Our results show that extraversion and agreeableness were positively related to attitudes toward fun. Extraversion and emotional stability (low neuroticism) were positively related to the level of experienced fun. In general, our sample expressed positive attitudes regarding the appropriateness, salience, and consequences of having fun at work. Additionally, those who reported experiencing greater levels of workplace fun had significantly lower emotional exhaustion and emotional dissonance, as well as higher job satisfaction. Implications for healthcare institutions are discussed.

Although anxiety sensitivity has been primarily conceptualized as a dimensional latent construct, empirical evidence suggests that it also maintains a latent class structure, reflecting low-, moderate-, and high-risk underlying classes. The present study sought to explore whether these anxiety sensitivity classes moderated the relations between the degree of pre-quit reductions in anxiety sensitivity and the severity of nicotine withdrawal symptoms and craving experienced on quit-day. Participants included 195 adult smokers (47% female; Mage=39.4) participating in a larger "anxiety sensitivity reduction-smoking cessation" intervention trial. Anxiety sensitivity class significantly moderated relations between pre-quit reduction in anxiety sensitivity and quit-day craving. Specifically, smokers within the anxiety sensitivity high-risk class, who also demonstrated lesser pre-quit reductions in anxiety sensitivity, experienced the highest levels of craving on quit-day. These findings highlight the importance of 'high-risk' classes of anxiety sensitivity to better understand the experience of craving on quit day. Copyright © 2016. Published by Elsevier Ltd.

The influence of gravitoinertial force level on oculomotor and perceptual responses to Coriolis, cross-coupling stimulation

Dizio, Paul; Lackner, James R.; Evanoff, John N.

1987-01-01

The goal of the present experiment was to determine whether gravitoinertial force magnitude influences oculomotor and perceptual responses to Coriolis cross-coupling stimulation. Blindfolded subjects who were rotating at constant velocity were asked to make standardized head movements during the free-fall and high-force phases of parabolic flight, and the characteristics of their horizontal nystagmus and the magnitude of their experienced self-motion were measured. Both responses were less intense in the free-fall periods than in the high-force periods. These findings suggest that the response to semicircular canal stimulation depends on the background level of gravitoinertial force.

Specific anti-human leukocyte antigen antibodies (HLA) in the post-transplant period may be present with acute rejection episodes (ARE), and high soluble CD30 (sCD30) serum levels may be a risk factor for ARE and graft loss. HLA cross-matching, panel reactive antibodies (PRA), and sCD30 levels were determined prior to transplantation in 72 patients. Soluble CD30 levels and PRA were re-assessed at day 7, 14, 21, and 28, and monthly up to the sixth.   Twenty-four subjects had a positive PRA and 17 experienced ARE. Nine of 17 ARE subjects demonstrated positive PRA and 16 had HLA mismatches. Positive PRA was more frequent in ARE subjects (p = 0.03). Eight subjects with ARE had donor-specific antibodies (DSA) in serum samples pre-transplantation, two subjects developed DSA. Three subjects without ARE had positive PRA only in post-transplantation samples. Soluble CD30 levels were higher in pre-transplant samples and ARE subjects than non-ARE subjects (p = 0.03). Post-transplant sCD30 levels were elevated in subjects who experienced rejection and were significantly higher at seven d (p = 0.0004) and six months (p = 0.03). Higher sCD30 levels following transplant were associated with ARE. Elevated sCD30 levels may represent a risk factor for acute rejection. © 2009 John Wiley & Sons A/S.

Clinical success of oral implants is related to primary stability and osseointegration. These parameters are associated with delicate surgical techniques. We herein studied whether template-guided drilling has a significant influence on drillholes diameter and accuracy in an in vitro model. Fresh cadaveric porcine mandibles were used for drilling experiments of four experimental groups. Each group consisted of three operators, comparing guide templates for drilling with free-handed procedure. Operators without surgical knowledge were grouped together, contrasting highly experienced oral surgeons in other groups. A total of 180 drilling actions were performed, and diameters were recorded at multiple depth levels, with a precision measuring instrument. Template-guided drilling procedure improved accuracy on a very significant level in comparison with free-handed drilling operation (p ≤ 0.001). Inaccuracy of free-handed drilling became more significant in relation to measurement depth. High homogenic uniformity of template-guided drillholes was significantly stronger than unguided drilling operations by highly experienced oral surgeons (p ≤ 0.001). Template-guided drilling procedure leads to significantly enhanced accuracy. Significant results compared to free-handed drilling actions were achieved, irrespective of the clinical experience level of the operator. Template-guided drilling procedures lead to a more predictable clinical diameter. It shows that any set of instruments has to be carefully chosen to match the specific implant system. The current in vitro study is implicating an improvement of implant bed preparation but needs to be confirmed in clinical studies.

Stress and burnout among healthcare professionals working in a mental health setting in Singapore.

International literature suggests that the experience of high levels of stress by healthcare professionals has been associated with decreased work efficiency and high rates of staff turnover. The aims of this study are to identify the extent of stress and burnout experienced by healthcare professionals working in a mental health setting in Singapore and to identify demographic characteristics and work situations associated with this stress and burnout. A total of 220 Singaporean mental health professionals completed a cross-sectional survey, which included measures of stress, burnout (exhaustion and disengagement), participants' demographic details, and working situation. Independent t-tests and one-way ANOVAs were used to examine between-group differences in the dependent variables (stress and burnout). Analyses revealed that healthcare professionals below the age of 25, those with less than five years experience, and those with the lowest annual income, reported the highest levels of stress and burnout. No significant differences were found with other demographic or work situation variables. Findings suggest that healthcare professionals working in a mental health setting in Singapore are experiencing relatively high levels of stress and burnout. It is important that clinicians, administrators and policy makers take proactive steps to develop programs aimed at reducing stress and burnout for healthcare professionals. These programs are likely to also increase the well-being and resilience of healthcare professionals and improve the quality of mental health services in Singapore. Copyright © 2015 Elsevier B.V.

Drastic increases in global carbon emissions in the past century have led to elevated sea surface temperatures that negatively affect coral reef organisms. Worldwide coral bleaching-related mortality is increasing and data has shown even isolated and protected reefs are vulnerable to the effects of global climate change. In 2014 and 2015, coral reefs in the main Hawaiian Islands (MHI) suffered up to 90% bleaching, with higher than 50% subsequent mortality in some areas. The location and severity of bleaching and mortality was strongly influenced by the spatial and temporal patterns of elevated seawater temperatures. The main objective of this research was to understand the spatial extent of bleaching mortality in Hanauma Bay Nature Preserve (HBNP), O'ahu, Hawai'i to gain a baseline understanding of the physical processes that influence localized bleaching dynamics. Surveys at HBNP in October 2015 and January 2016 revealed extensive bleaching (47%) and high levels of coral mortality (9.8%). Bleaching was highly variable among the four HBNP sectors and ranged from a low of ∼31% in the central bay at Channel (CH) to a high of 57% in the area most frequented by visitors (Keyhole; KH). The highest levels of bleaching occurred in two sectors with different circulation patterns: KH experienced comparatively low circulation velocity and a low temperature increase while Witches Brew (WB) and Backdoors (BD) experienced higher circulation velocity and higher temperature increase. Cumulative mortality was highest at WB (5.0%) and at BD (2.9%) although WB circulation velocity is significantly higher. HBNP is minimally impacted by local factors that can lead to decline such as high fishing pressure or sedimentation although human use is high. Despite the lack of these influences, high coral mortality occurred. Visitor impacts are strikingly different in the two sectors that experienced the highest mortality evidenced by the differences in coral cover associated with visitor use however, coral mortality was similar. These results suggest that elevated temperature was more influential in coral bleaching and the associated mortality than high circulation or visitor use.

Effort-reward imbalance and burnout among nurses.

PubMed

Bakker, A B; Killmer, C H; Siegrist, J; Schaufeli, W B

2000-04-01

This study among a sample of 204 German nurses tested the hypothesis that an imbalance of high extrinsic efforts spent (i.e. job demands) and low extrinsic rewards obtained (e.g. poor promotion prospects) are associated with the burnout syndrome: the depletion of nurses' emotional resources. The results of a series of analyses of variances confirmed this hypothesis, by showing that those nurses who experienced an effort-reward imbalance (ERI) reported higher levels on two of the three core dimensions of burnout (i.e. emotional exhaustion and depersonalization) than those who did not experience such an imbalance. Moreover - as additionally hypothesized - significant interaction effects indicated that burnout (i.e. emotional exhaustion and reduced personal accomplishment) was particularly prevalent among those nurses who experienced ERI and put relatively high intrinsic effort into their jobs, as reflected by their strong tendency to be personally in control over job conditions.

2014-01-01

Over the past 30 years, the prevalence of noise-induced hearing loss among adolescents and young adults has increased. This study aimed to address the current dearth of literature implicating excessive nightclub sound levels (more than 85 dB) as a direct cause of auditory symptoms related to noise-induced hearing loss. A questionnaire was completed by 325 students to gauge the frequency of auditory symptoms after nightclub attendance, and to explore knowledge and opinions about noise levels in nightclubs. The findings showed that 88.3 per cent of students experienced tinnitus after leaving a nightclub and 66.2 per cent suffered impaired hearing the following morning. In terms of behaviour, 73.2 per cent of students said that the risk of hearing damage would not affect their nightclub attendance, but most students (70.2 per cent) felt that noise levels in nightclubs should be limited to safe volumes. A high proportion of students reported experiencing symptoms related to noise-induced hearing loss after attending a nightclub. These findings are relevant to policy makers.

Pubertal timing and educational careers: a longitudinal study.

PubMed

Koivusilta, L; Rimpelä, A

2004-01-01

Pubertal timing is related to several dimensions of adolescent development. No studies concern its associations with educational careers. To investigate whether pubertal timing predicts attained educational level and how school achievement, educational track and sociodemographic background in adolescence mediate this relationship. Survey data (1981, 1983, 1985) from samples of 12-16-year-old Finns (n = 7674) were linked with the respondents' attained education in 1998 (ages 27-33). Ages of menarche and of first ejaculation were indicators of pubertal timing. Among boys who by age 16 had experienced early, average or late pubertal timing, 13%, 12%, and 6% reached upper tertiary educational level, respectively. Boys with early or average puberty often came from high social strata and selected educational tracks with good prospects. In girls, sociodemographic factors rather than pubertal timing predicted attained educational level. Early or average onset of puberty plays a role in dividing boys into educational tracks after compulsory schooling. Support should be given to boys, whose delayed pubertal development makes them immature to making appropriate educational decisions and to boys who may have experienced early puberty but fail to exploit educational opportunities available for them.

Reliability in perceptual analysis of voice quality.

2005-12-01

This study focuses on speaking voice quality in male teachers (n = 35) and male actors (n = 36), who represent untrained and trained voice users, because we wanted to investigate normal and supranormal voices. In this study, both substantial and methodologic aspects were considered. It includes a method for perceptual voice evaluation, and a basic issue was rater reliability. A listening group of 10 listeners, 7 experienced speech-language therapists, and 3 speech-language therapist students evaluated the voices by 15 vocal characteristics using VA scales. Two sets of voice signals were investigated: text reading (2 loudness levels) and sustained vowel (3 levels). The results indicated a high interrater reliability for most perceptual characteristics. Connected speech was evaluated more reliably, especially at the normal level, but both types of voice signals were evaluated reliably, although the reliability for connected speech was somewhat higher than for vowels. Experienced listeners tended to be more consistent in their ratings than did the student raters. Some vocal characteristics achieved acceptable reliability even with a smaller panel of listeners. The perceptual characteristics grouped in 4 factors reflected perceptual dimensions.

Burnout among nursing staff in accident and emergency and acute medicine: a comparative study.

PubMed

Gillespie, Mark; Melby, Vidar

2003-11-01

This study was designed to identify the prevalence of burnout among nurses working in Accident and Emergency (A & E) and acute medicine, to establish factors that contribute to stress and burnout, to determine the experiences of nurses affected by it and highlight its effects on patient care and to determine if stress and burnout have any effects on individuals outside the clinical setting. A triangulated research design was used incorporating quantitative and qualitative methods. Maslach Burnout Inventory was used. Nurses working in acute medicine experienced higher levels of emotional exhaustion than their A & E counterparts. The overall level of depersonalization was low. High levels of personal accomplishment were experienced less by junior members of staff. Stress and burnout have far reaching effects both for nurses in their clinical practice and personal lives. If nurses continue to work in their current environment without issues being tackled, then burnout will result. The science of nursing does not have to be painful, but by recognition of the existence of stress and burnout we can take the first steps towards their prevention.

Assessing the professional development needs of experienced nurse executive leaders.

Leach, Linda Searle; McFarland, Patricia

2014-01-01

The objective of this study was to identify the professional development topics that senior nurse leaders believe are important to their advancement and success. Senior/experienced nurse leaders at the executive level are able to influence the work environment of nurses and institutional and health policy. Their development needs are likely to reflect this and other contemporary healthcare issues and may be different from middle and frontline managers. A systematic way of assessing professional development needs for these nurse leaders is needed. A descriptive study using an online survey was distributed to a convenience sample of nurse leaders who were members of the Association of California Nurse Leaders (ACNL) or have participated in an ACNL program. Visionary leadership, leading complexity, and effective teams were the highest ranked leadership topics. Leading change, advancing health: The future of nursing, healthy work environments, and healthcare reform were also highly ranked topics. Executive-level nurse leaders are important to nurse retention, effective work environments, and leading change. Regular assessment and attention to the distinct professional development needs of executive-level nurse leaders are a valuable human capital investment.

The CMS experiment implements a sophisticated two-level triggering system composed of Level-1, instrumented by custom-design hardware boards, and a software High-Level-Trigger. A new Level-1 trigger architecture with improved performance is now being used to maintain the thresholds that were used in LHC Run I for the more challenging luminosity conditions experienced during Run II. The upgrades to the calorimetry trigger will be described along with performance data. The algorithms for the selection of final states with electrons and photons, both for precision measurements and for searches of new physics beyond the Standard Model, will be described in detail.

Abstract A total of 184 cases of surgically treated male prolactinoma were analyzed retrospectively to summarize the outcome of this surgical intervention. We analyzed the general characteristics, clinical manifestations, hormone levels, imaging features, preoperative treatments, surgical outcomes, pathology results, and follow-up records for all included patients. The most common clinical manifestations included sexual dysfunction (47.4%), headache (55.9%), and visual disturbance (46.7%). Serum prolactin levels ranged from 150 to 204,952 ng/mL. Tumor size varied from 6 to 70 mm. Pituitary adenomas grew in a parasellar pattern with visual deficits occurring 40.7% of the time. After surgical therapy, 88.6% of patients achieved symptom relief, and 98.4% experienced an immediate postoperative decline in prolactin level. Fifty-seven patients (31.0%) achieved initial remission, and 26 patients (45.6%) experienced recurrence. Hence, our results suggest that in male prolactinoma characterized by a large pituitary diameter and high serum prolactin level, tumor size predicts the degree of gross resection. The prognostic predictors included preoperative tumor growth pattern and Ki-67 index. Citation: Yi-jun S, Mei-ting C, Wei L, Bing X, Yong Y, Ming F, Ren-zhi W.

Lavers, David A.; Hannah, David M.; Bradley, Chris

2015-04-01

Groundwater is an important water resource and globally it represents the largest distributed store of freshwater. In southern England, groundwater is a major source for public water supply, and many aquifers have recently experienced both extreme low and high groundwater levels. In this paper, we use observations of precipitation, river discharge and groundwater levels (1964-2010) and an atmospheric reanalysis to explore the large-scale climate patterns preceding the nine highest and lowest March river discharge and groundwater levels in the chalk catchment of the River Lambourn (Berkshire Downs, southern England). Peak monthly precipitation is shown to occur from October to January, while the highest river discharge and groundwater levels are found from February to April. For high discharge/groundwater levels, composite anomaly patterns of the mean sea level pressure show a stronger than average pressure gradient across the North Atlantic Ocean, with enhanced water vapour transport across southern England. For the lowest discharge/groundwater levels, a blocking high pressure system is found across the British Isles deflecting storms and precipitation to the north. Significantly, the intra-composite variability suggests that different sequences of atmospheric states may lead to high and low discharge/groundwater events.

This study describes trends in the supply and the need for behavioral health professionals in Nebraska. A state-level health workforce database was used to estimate the behavioral health workforce supply and need. Compared with national estimates, Nebraska has a lower proportion of all categories of behavioral health professionals. The majority of Nebraska counties have unusually high needs for mental health professionals, with rural areas experiencing a decline in the supply of psychiatrists over the last decade. Availability of robust state-level health workforce data can assist in crafting effective policy for successful systems change, particularly for behavioral health.

Differential impacts of public health insurance expansions at the local level.

Baughman, Reagan

2007-03-01

Dramatic expansions in public health insurance eligibility for U.S. children have only modestly reduced the aggregate number of uninsured at the national level. This paper shows that Medicaid and SCHIP expansions had different impacts on child health insurance coverage patterns based upon local labor market characteristics. Metropolitan areas with high levels of unemployment were most likely to have seen improvements in overall insurance coverage for children between 1990 and 2001. Areas with greater fractions of employment in services, retail or wholesale trade were more likely to have experienced increases in public coverage but not overall coverage rates.

Identifying seasonal and temporal trends in the pressures experienced by hospitals related to unscheduled care.

Walker, N J; Van Woerden, H C; Kiparoglou, V; Yang, Y

2016-07-26

As part of an electronic dashboard operated by Public Health Wales, senior managers at hospitals in Wales report daily "escalation" scores which reflect management opinion on the pressure a hospital is experiencing and ability to meet ongoing demand with respect to unscheduled care. An analysis was undertaken of escalation scores returned for 18 hospitals in Wales between the years 2006 and 2014 inclusive, with a view to identifying systematic temporal patterns in pressure experienced by hospitals in relation to unscheduled care. Exploratory data analysis indicated the presence of within-year cyclicity in average daily scores over all hospitals. In order to quantify this cyclicity, a Generalised Linear Mixed Model was fitted which incorporated a trigonometric function (sine and cosine) to capture within-year change in escalation. In addition, a 7-level categorical day of the week effect was fitted as well as a 3-level categorical Christmas holiday variable based on patterns observed in exploration of the raw data. All of the main effects investigated were found to be statistically significant. Firstly, significant differences emerged in terms of overall pressure reported by individual hospitals. Furthermore, escalation scores were found to vary systematically within-year in a wave-like fashion for all hospitals (but not between hospitals) with the period of highest pressure consistently observed to occur in winter and lowest pressure in summer. In addition to this annual variation, pressure reported by hospitals was also found to be influenced by day of the week (low at weekends, high early in the working week) and especially low over the Christmas period but high immediately afterwards. Whilst unpredictable to a degree, quantifiable pressure experienced by hospitals can be anticipated according to models incorporating systematic temporal patterns. In the context of finite resources for healthcare services, these findings could optimise staffing schedules and inform resource utilisation.

Child and Caregiver Concordance of Potentially Traumatic Events Experienced by Orphaned and Abandoned Children

Exposure to trauma is associated with significant emotional and behavioral difficulties among children (Perepletchikova & Kaufman, 2010). Overall, reports of trauma and violence experienced by children are discrepant from those of their caregivers (Lewis et al., 2012). Even less is known about the extent of concordance between orphans and their caregivers. This study examines the correlates of concordance in reported traumatic experiences between 1,269 orphaned and abandoned children (OAC) and their caregivers. The OAC lived in family-settings in 5 low and middle income countries and were part of a longitudinal study, “Positive Outcomes for Orphans” (POFO) that enrolled children aged 6 to 12 at baseline. By examining concordance with respect to specific types of trauma reported, this study expands the understanding of who reports which types of traumas experienced by orphaned and abandoned children, thereby improving the potential to provide targeted interventions for children who have experienced such events. In this study, children and caregivers were asked separately if the child had experienced different types of potentially traumatic events. Children were significantly more likely to report physical abuse, sexual abuse and family violence than were caregivers. Caregivers were significantly more likely than children to report natural disasters and accidents. High levels of concordance were found in the reporting of wars, riots, killings, and deaths in the family. The impacts of trauma on behavior and mental health are profound, and highly effective interventions targeting sequelae of childhood trauma are currently being developed for use in low resource areas. Findings from this study demonstrate that it is feasible to conduct screening for potentially traumatic events utilizing child self-report in resource limited settings and that child self-report is crucial in evaluating trauma, particularly family violence and physical or sexual assault.

To treat lupus nephritis effectively, proper identification of the histologic class is essential. Although the classification system for lupus nephritis is nearly 40 years old, remarkably few studies have investigated interobserver agreement. Interobserver agreement among nephropathologists was studied, particularly with respect to the recognition of class III/IV lupus nephritis lesions, and possible causes of disagreement were determined. A link to a survey containing pictures of 30 glomeruli was provided to all 360 members of the Renal Pathology Society; 34 responses were received from 12 countries (a response rate of 9.4%). The nephropathologist was asked whether glomerular lesions were present that would categorize the biopsy as class III/IV. If so, additional parameters were scored. To determine the interobserver agreement among the participants, κ or intraclass correlation values were calculated. The intraclass correlation or κ-value was also calculated for two separate levels of experience (specifically, nephropathologists who were new to the field or moderately experienced [less experienced] and nephropathologists who were highly experienced). Intraclass correlation for the presence of a class III/IV lesion was 0.39 (poor). The κ/intraclass correlation values for the additional parameters were as follows: active, chronic, or both: 0.36; segmental versus global: 0.39; endocapillary proliferation: 0.46; influx of inflammatory cells: 0.32; swelling of endothelial cells: 0.46; extracapillary proliferation: 0.57; type of crescent: 0.46; and wire loops: 0.35. The highly experienced nephropathologists had significantly less interobserver variability compared with the less experienced nephropathologists (P=0.004). There is generally poor agreement in terms of recognizing class III/IV lesions. Because experience clearly increases interobserver agreement, this agreement may be improved by training nephropathologists. These results also underscore the importance of a central review by experienced nephropathologists in clinical trials. Copyright © 2015 by the American Society of Nephrology.

Domestic violence and abuse (DVA) are associated with increased risk of mental illness, but we know little about the mental health of female DVA survivors seeking support from domestic violence services. Our goal was to characterise the demography and mental health of women who access specialist DVA services in the United Kingdom and to investigate associations between severity of abuse and measures of mental health and health state utility, accounting for important confounders and moderators. Baseline data on 260 women enrolled in a randomized controlled trial of a psychological intervention for DVA survivors were analysed. We report the prevalence of and associations between mental health status and severity of abuse at the time of recruitment. We used logistic and normal regression models for binary and continuous outcomes, respectively. The following mental health measures were used: Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), Patient Health Questionnaire, Generalised Anxiety Disorder Assessment, and the Posttraumatic Diagnostic Scale to measure posttraumatic stress disorder (PTSD). The Composite Abuse Scale (CAS) measured abuse. Exposure to DVA was high, with a mean CAS score of 56 (SD 34). The mean CORE-OM score was 18 (SD 8) with 76% above the clinical threshold (95% confidence interval: 70-81%). Depression and anxiety levels were high, with means close to clinical thresholds, and more than three-quarters of respondents recorded PTSD scores above the clinical threshold. Symptoms of mental illness increased stepwise with increasing severity of DVA. Women DVA survivors who seek support from DVA services have recently experienced high levels of abuse, depression, anxiety, and especially PTSD. Clinicians need to be aware that patients presenting with mental health conditions or symptoms of depression or anxiety may be experiencing or have experienced DVA. The high psychological morbidity in this population means that trauma-informed psychological support is needed for survivors who seek support from DVA services.

Background Domestic violence and abuse (DVA) are associated with increased risk of mental illness, but we know little about the mental health of female DVA survivors seeking support from domestic violence services. Objective Our goal was to characterise the demography and mental health of women who access specialist DVA services in the United Kingdom and to investigate associations between severity of abuse and measures of mental health and health state utility, accounting for important confounders and moderators. Design Baseline data on 260 women enrolled in a randomized controlled trial of a psychological intervention for DVA survivors were analysed. We report the prevalence of and associations between mental health status and severity of abuse at the time of recruitment. We used logistic and normal regression models for binary and continuous outcomes, respectively. The following mental health measures were used: Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM), Patient Health Questionnaire, Generalised Anxiety Disorder Assessment, and the Posttraumatic Diagnostic Scale to measure posttraumatic stress disorder (PTSD). The Composite Abuse Scale (CAS) measured abuse. Results Exposure to DVA was high, with a mean CAS score of 56 (SD 34). The mean CORE-OM score was 18 (SD 8) with 76% above the clinical threshold (95% confidence interval: 70–81%). Depression and anxiety levels were high, with means close to clinical thresholds, and more than three-quarters of respondents recorded PTSD scores above the clinical threshold. Symptoms of mental illness increased stepwise with increasing severity of DVA. Conclusions Women DVA survivors who seek support from DVA services have recently experienced high levels of abuse, depression, anxiety, and especially PTSD. Clinicians need to be aware that patients presenting with mental health conditions or symptoms of depression or anxiety may be experiencing or have experienced DVA. The high psychological morbidity in this population means that trauma-informed psychological support is needed for survivors who seek support from DVA services. PMID:26860876

Harada, Hideyuki, E-mail: h.harada@scchr.jp; Seto, Takashi; Igawa, Satoshi

Purpose: To investigate the safety and efficacy of concurrent vinorelbine and thoracic radiotherapy in elderly patients with locally advanced non-small-cell lung cancer (NSCLC). Methods and Materials: Eligible patients were 71 years of age or older with unresectable Stage III NSCLC. Patients were treated with thoracic radiotherapy (60 Gy) and concurrent vinorelbine (20 mg/m{sup 2} in Level 1 and 25 mg/m{sup 2} in Level 2) on Days 1 and 8 every 3 weeks for two cycles, followed by adjuvant vinorelbine (25 mg/m{sup 2}) on Days 1 and 8 every 3 weeks for two cycles. Results: Four patients were enrolled at Levelmore » 1. One patient experienced Grade 3 febrile neutropenia at Level 1 and the dose was escalated to Level 2. At Level 2, 2 of 6 patients experienced dose-limiting toxicities (Grade 4 neutropenia in 1 patient and Grade 3 infection in another). Three of 6 patients developed late Grade 2 or 3 pneumonitis. Therefore, the dose was de-escalated to Level 1. An additional 6 patients were enrolled at Level 1, 4 of whom experienced dose-limiting toxicities (incomplete radiotherapy because of Grade 2 pneumonitis in 1 patient and Grade 3 infection in 1, Grade 3 febrile neutropenia in 1, and Grade 3 esophagitis in 1). Moreover, late Grade 3 pneumothorax and Grade 5 pneumonitis occurred in 1 and 1 patient, respectively. Overall, Grade 2, 3 and 5 pneumonitis occurred in 3, 3, and 1 among 16 patients, respectively. Conclusions: Concurrent vinorelbine and thoracic radiotherapy resulted in a high incidence of severe pneumonitis when the standard dose of this agent was used for elderly patients. We therefore recommend caution in the use of this regimen and schedule for elderly patients.« less

Relationship Satisfaction and Risk Factors for Suicide.

Previous studies suggest that troubled romantic relationships are associated with higher risk factors for mental health. However, studies examining the role of relationship satisfaction in suicide risk factors are scarce. We investigated differences in risk factors for suicide between individuals with high relationship satisfaction, individuals with low relationship satisfaction, and singles. Furthermore, we explored patterns of experiencing, and dealing with, conflicts in the relationship and examined associations with suicide risk factors. In this cross-sectional study, we assessed relationship status, relationship satisfaction, specific types of relationship conflicts, and suicide risk factors (i.e., suicidal ideation, hopelessness, depression) with questionnaires among 382 individuals in Austria. Risk factors for suicide were higher among singles than among individuals in happy relationships, but highest among those with low relationship satisfaction [corrected]. Participants reporting a high number of unsolved conflicts in their relationship had higher levels of suicidal ideation, hopelessness, and depression than individuals who tend to solve issues with their partner amicably or report no conflicts. Relationship satisfaction and relationship conflicts reflect risk factors for suicide, with higher levels of suicidal ideation, hopelessness, and depression reported by individuals who mentioned unsolved conflicts with their partner and experienced low satisfaction with their relationship.

Unintended pregnancies in Hamedan, Iran: levels and determinants.

2018-06-19

The recent limitation in the provision of publicly-funded family planning services in Iran has concerned stakeholders in reproductive health about the incidence of unintended pregnancies. This study used data from Hamedan Survey of Fertility, conducted in April-June 2015 among a representative sample of 3,000 married women aged 15-49 years living in the city of Hamedan (Iran), to estimate levels of unintended pregnancies and examine factors related to pregnancy intentions for the most recent birth, using multinomial logistic regression analyses. Results showed that 23% of pregnant women reported their pregnancy as unintended (17% mistimed and 6% unwanted). Moreover, unintended pregnancies in the five years preceding the survey were the result of failures of withdrawal (35%) and of modern contraceptive use (33%), along with contraceptive discontinuation (23%) and nonuse (9%). Multivariate results indicated that the risk of unintended pregnancy was lower among women reporting modern contraceptive failures and lower among those reporting contraceptive discontinuation and nonuse, compared with women experiencing withdrawal failures. The high incidence of unintended pregnancies among women experiencing contraceptive failures and discontinuation imply their high unmet need for contraceptive knowledge and counseling rather than for access to contraceptive methods.

How do people feel during extreme collective rituals? Despite longstanding speculation, few studies have attempted to quantify ritual experiences. Using a novel pre/post design, we quantified physiological fluctuations (heart rates) and self-reported affective states from a collective fire-walking ritual in a Mauritian Hindu community. Specifically, we compared changes in levels of happiness, fatigue, and heart rate reactivity among high-ordeal participants (fire-walkers), low-ordeal participants (non-fire-walking participants with familial bonds to fire-walkers) and spectators (unrelated/unknown to the fire-walkers). We observed that fire-walkers experienced the highest increase in heart rate and reported greater happiness post-ritual compared to low-ordeal participants and spectators. Low-ordeal participants reported increased fatigue after the ritual compared to both fire-walkers and spectators, suggesting empathetic identification effects. Thus, witnessing the ritualistic suffering of loved ones may be more exhausting than experiencing suffering oneself. The findings demonstrate that the level of ritual involvement is important for shaping affective responses to collective rituals. Enduring a ritual ordeal is associated with greater happiness, whereas observing a loved-one endure a ritual ordeal is associated with greater fatigue post-ritual. PMID:24586315

Positive Parenting Interacts with Child Temperament and Negative Parenting to Predict Children’s Socially Appropriate Behavior

2017-01-01

This study examined the effects of parents’ positive and negative affect and behavior while interacting with their preschool child and the moderating role of child temperament in predicting children’s subsequent difficulty with socially appropriate behavior around school-entry. Independent observational measures were used to assess child temperament (dysphoria; exuberance) and parenting at age 3, and multi-informant reports of child socially appropriate behavior were collected at age 6 (N = 219). Hierarchical multiple regression analyses revealed that children’s temperamental dysphoria moderated the relationship between positive parenting and later socially appropriate behavior. High- and low-dysphoric children trended in opposite directions; highly dysphoric children experienced greater difficulty with socially appropriate behavior as levels of positive parenting increased, whereas low-dysphoric children experienced less difficulty with socially appropriate behavior with higher levels of positive parenting. There was also an interaction between positive and negative parenting, whereby the combination of elevated positive and negative parenting predicted children’s later difficulty with socially appropriate behavior. The findings suggest that positive parenting interacts with early child temperament and negative parenting to impact the development of children’s socially appropriate behavior. PMID:28824223

EARLY HEAD START FAMILIES' EXPERIENCES WITH STRESS: UNDERSTANDING VARIATIONS WITHIN A HIGH-RISK, LOW-INCOME SAMPLE.

The federal Early Head Start program provides a relevant context to examine families' experiences with stress since participants qualify on the basis of poverty and risk. Building on previous research that has shown variations in demographic and economic risks even among qualifying families, we examined possible variations in families' perceptions of stress. Family, parent, and child data were collected to measure stressors and risk across a variety of domains in families' everyday lives, primarily from self-report measures, but also including assay results from child cortisol samples. A cluster analysis was employed to examine potential differences among groups of Early Head Start families. Results showed that there were three distinct subgroups of families, with some families perceiving that they experienced very high levels of stress while others perceived much lower levels of stress despite also experiencing poverty and heightened risk. These findings have important implications in that they provide an initial step toward distinguishing differences in low-income families' experiences with stress, thereby informing interventions focused on promoting responsive caregiving as a possible mechanism to buffer the effects of family and social stressors on young children. © 2017 Michigan Association for Infant Mental Health.

This study examines risk and protective factors associated with experiencing homelessness in the year after "aging out" of foster care. Using a state-level integrated administrative database, we identified 1,202 emerging adults in Washington State who exited foster care between July 2010 and June 2012. Initial bivariate analyses were conducted to assess the association between candidate predictive factors and an indicator of homelessness in a 12-month follow-up period. After deploying a stepwise regression process, the final logistic regression model included 15 predictive factors. Youth who were parents, who had recently experienced housing instability, or who were African American had approximately twice the odds of experiencing homelessness in the year after exiting foster care. In addition, youth who had experienced disrupted adoptions, had multiple foster care placements (especially in congregate care settings), or had been involved with the juvenile justice system were more likely to become homeless. In contrast, youth were less likely to experience homelessness if they had ever been placed with a relative while in foster care or had a high cumulative grade point average relative to their peers. © Society for Community Research and Action 2016.

Production loss among employees perceiving work environment problems.

Lohela-Karlsson, Malin; Hagberg, Jan; Bergström, Gunnar

2015-08-01

The overall aim of this explorative study was to investigate the relationship between factors in the psychosocial work environment and work environment-related production loss. Employees at a Swedish university were invited to answer a workplace questionnaire and were selected for this study if they reported having experienced work environment-related problems in the past 7 days (n = 302). A stepwise logistic regression and a modified Poisson regression were used to identify psychosocial work factors associated with work environment-related production loss as well as to identify at what level those factors are associated with production loss. Employees who reported having experienced work environment problems but also fair leadership, good social climate, role clarity and control of decision had significantly lower levels of production loss, whereas employees who reported inequality and high decision demands reported significantly higher levels of production loss. Never or seldom experiencing fair leadership, role clarity, equality, decision demands and good social climate increase the risk of production loss due to work environment problems, compared to those who experience these circumstances frequently, always or most of the time. Several psychosocial work factors are identified as factors associated with a reduced risk of production losses among employees despite the nature of the work environment problem. Knowledge of these factors may be important not only to reduce employee ill-health and the corresponding health-related production loss, but also reduce immediate production loss due to work environment-related problems.

Stress of caring for children: the role of perceived racism.

Regardless of race, most mothers experience stress related to concerns about their children. African American mothers may experience the additional stress of their child (ren) experiencing racism. We describe the stress that African American women have about their children experiencing racism. The Telephone-Administered Perceived Racism Scale (TPRS) was administered to 476 African American women ages 36 to 53 who were members of a prepaid health plan. The 8-item Concern for Children scale, 1 of the 5 TPRS scales, was completed by 382 women and assessed the level of concern women have about their children experiencing racism. The responses ranged from "not at all concerned" to "very concerned." For 6 of the 8 items, more than 60% reported being "very concerned" for their children. Items of highest concern involved institutionalized racism with more than 70% reported being very concerned about their children being harmed or harassed by the police or getting stopped in a predominantly white neighborhood. Respondents were less concerned about their children being considered less attractive than their white counterparts and/or being excluded from social events, activities, or groups. Level of concern was not related to income or education. Unsurprisingly, respondents who reported high levels of perceived racism also reported greater concern for their child(ren). These findings highlight an additional stressor related to childrearing in a "race-conscious" society. Future research on stress and African American women's health should include this additional stressor.

Although Western mental health services are increasingly finding themselves concerned with assisting traumatized individuals migrating from other countries, trauma and posttraumatic stress disorder (PTSD) are under-detected and undiagnosed in psychiatric populations. This study examined and compared rates of traumatic experiences, frequency of traumatic events, trauma symptomatology levels, rates of torture, rates of PTSD and chart documentation of trauma and PTSD between (a) Irish and migrant service-users and (b) forced migrant and voluntary migrant service-users in Dublin, Ireland. Data were gathered from 178 psychiatric outpatients attending using a sociodemographic questionnaire, the Harvard Trauma Questionnaire-Revised Cambodian Version and the SCID-I/P. A substantial number of service-users had experienced at least one lifetime trauma (71.3%), and a high percentage of both the Irish (47.4%) and migrant groups (70.3%) of service-users had experienced two or more events. Overall, analyses comparing rates between Irish, forced migrant and voluntary migrant service-users found that forced migrants displayed more traumatic life events, posttraumatic symptoms, and higher levels of PTSD than their voluntary migrant and Irish counterparts, with over 50% experiencing torture prior to arrival in Ireland. The lifetime rate of PTSD in the overall sample was 15.7% but only 53.57% of cases were documented in patient charts. The results of this study are informative about the nature and extent of the problem of trauma and PTSD among migrant mental health service users as well as highlighting the under-detected levels of trauma among native-born service users.

Drug-drug interaction between methotrexate and levetiracetam resulting in delayed methotrexate elimination.

PubMed

Bain, Emily; Birhiray, Ruemu E; Reeves, David J

2014-02-01

To report a case of delayed methotrexate (MTX) elimination while receiving concomitant levetiracetam. A 46-year-old man with relapsed osteosarcoma of the base of the skull receiving high-dose MTX tolerated his first cycle of MTX with elimination to nontoxic MTX levels (≤0.1 µmol/L) within 90 hours. After hospital discharge, the patient experienced seizures secondary to brain metastasis and started on levetiracetam, which was continued as maintenance therapy. The patient experienced delayed MTX elimination during cycles 2, 3, and 4 while receiving levetiracetam. On average, elimination to nontoxic MTX levels took 130 hours (106-144 hours). Before the fifth cycle of MTX, lorazepam was substituted for the levetiracetam. MTX was eliminated to nontoxic levels within 95 hours. During all cycles, the patient received standard supportive care and serum creatinine remained stable. No other drugs known to interact with MTX were administered. This possible drug interaction has only been reported once in the pediatric population. With a score of 6 on the Drug Interaction Probability Scale for evaluating causation of drug interactions, it is probable that the delayed MTX elimination was caused by an interaction with levetiracetam. Coadministration of levetiracetam and MTX may result in delayed elimination of MTX, increasing the likelihood of toxicity. Consideration should be given to temporarily switching from levetiracetam to another antiepileptic (ie, lorazepam) to prevent this interaction. This is particularly important in those experiencing delayed elimination with prior cycles of concomitant MTX and levetiracetam or those at greater risk for MTX toxicity.

Aircraft control forces and EMG activity: comparison of novice and experienced pilots during simulated rolls, loops and turns.

Hewson, D J; McNair, P J; Marshall, R N

2000-08-01

Flying an aircraft requires a considerable degree of coordination, particularly during aerobatic activities such as rolls, loops and turns. Only one previous study has examined the magnitude of muscle activity required to fly an aircraft, and that was restricted to takeoff and landing maneuvers. The aim of this study was to examine the phasing of muscle activation and control forces of novice and experienced pilots during more complex simulated flight maneuvers. There were 12 experienced and 9 novice pilots who were tested on an Aermacchi flight simulator while performing a randomized set of rolling, looping, and turning maneuvers. Four different runaway trim settings were used to increase the difficulty of the turns (elevator-up, elevator-down, aileron-left, and aileron-right). Variables recorded included aircraft attitude, pilot applied forces, and electromyographic (EMG) activity. Discriminant function analysis was used to distinguish between novice and experienced pilots. Over all maneuvers, 70% of pilots were correctly classified as novice or experienced. Better levels of classification were achieved when maneuvers were analyzed individually (67-91%), although the maneuvers that required the greatest force application, elevator-up turns, were unable to discriminate between novice and experienced pilots. There were no differences in the phasing of muscle activity between experienced and novice pilots. The only consistent difference in EMG activity between novice and experienced pilots was the reduced EMG activity in the wrist extensors of experienced pilots (p < 0.05). The increased wrist extensor activity of the novice pilots is indicative of a distal control strategy, whereby distal muscles with smaller motor units are used to perform a task that requires precise control. Muscle activity sensors could be used to detect the onset of high G maneuvers prior to any change in aircraft attitude and control G-suit inflation accordingly.

A case study of Markdale High School's implementation of heterogeneously-grouped classes in English, mathematics, science, and social studies

NASA Astrophysics Data System (ADS)

Pierre-Louis, Fred

The purpose of this study was to describe Markdale High School's change from separate college preparatory and general level classes to heterogeneously-grouped classes in English, mathematics, science, and social studies, with particular emphasis on the principal's leadership style, change process, and teacher concerns (Hall & Hord, 2006) experienced during this effort. The researcher used Hall and Hord's (2006) Concern-Based Adoption Model (CBAM) as a conceptual framework. Specifically, the researcher applied three elements of the CBAM model: (a) the Twelve Principles of Change, (b) the Change Facilitator Styles, and (c) the Stages of Concerns. Hall and Hord's framework served as a lens through which the researcher analyzed all data. The researcher used a mixed-method (qualitative and quantitative) approach to answer the four research questions. The participants completed three instruments: (a) the Stages of Concern Questionnaire (SoCQ), (b) the Principles of Change Survey, and (c) the Facilitator Style Survey. All three instruments were self-report, paper-pencil surveys. The sample included 72 faculty members who experienced the change over the past three years. Findings from the three data sources and the school principal's comments during debriefing are indicated for each research question and reported by unit of analysis. Respective to the research questions, the researcher concluded that: (1) Markdale High School accomplished the change by implementing both structural and instructional changes supporting to the change to heterogeneous grouping; (2) even though teachers had divergent opinions on the school principal's facilitation style, the principal thought of himself as an incrementalist and a practitioner of differentiated facilitation styles; (3) while half of the faculty felt that they received formal training on heterogeneous grouping, (4) half felt that they did not have a choice in the decision-making process as it occurred with college preparatory and general level classes' and (5) even though members of the faculty had strong ideas about how to do things differently, the majority of faculty members from the English, mathematics, and social studies departments at Markdale High School were experiencing management concerns while faculty members from the science departments were experiencing personal concerns as described by Hall and Hord (2006). Finally, conclusions and recommendations for practice and future research are presented for each of the four research questions.

Community differences in the implementation of Strong Communities for Children.

In 1993, the U.S. Advisory Board on Child Abuse and Neglect recommended a neighborhood-based strategy to prevent child abuse and neglect. The Board further recommended the development of Prevention Zones to allow for testing of the effectiveness of community-wide child protection efforts in neighborhoods of differing population density, ethnic and cultural composition, and social and economic resources. Following the Board's recommendation, this article presents the results of a trial of the effectiveness of a neighborhood-based strategy in low- and high-resource communities. Using management, survey, and administrative data, the research showed that both community types experienced declines in founded cases of and injuries suggesting child maltreatment for children under age 5. Low-resource communities experienced greater levels of mobilization, as measured by community and institutional engagement, and a greater number of positive outcomes related to changes in the quality of life for families and community norms relative to child and family well-being. In particular, the low-resource communities experienced the largest increases in receiving help from neighbors, neighboring, perceived household safety for neighborhood children, and observed positive parenting. High-resource communities experienced greater increases in intermediate outcomes related to self-reported parenting practices. The findings suggest that, ultimately, community mobilization can occur and be an effective means of preventing child maltreatment across community types. It appears, however, that community mobilization may play a more significant role in low-resource communities. Copyright © 2014 Elsevier Ltd. All rights reserved.

Associations of pass-fail outcomes with psychological health of first-year medical students in a malaysian medical school.

2013-02-01

The demanding and intense environment of medical training can create excessive pressures on medical students that eventually lead to unfavorable consequences, either at a personal or professional level. These consequences can include poor academic performance and impaired cognitive ability. This study was designed to explore associations between pass-fail outcome and psychological health parameters (i.e. stress, anxiety, and depression symptoms). A cross-sectional study was conducted on a cohort of first-year medical students in a Malaysian medical school. The depression anxiety stress scale 21-item assessment (DASS-21) was administered to them right after the final paper of the first-year final examination. Their final examination outcomes (i.e. pass or fail) were traced by using their student identity code (ID) through the Universiti Sains Malaysia academic office. A total of 194 (98.0%) of medical students responded to the DASS-21. An independent t-test showed that students who passed had significantly lower stress, anxiety, and depression symptoms than those who failed the first-year final examination (P <0.05). Those who experienced moderate to high stress were at 2.43 times higher risk for failing the examination than those who experienced normal to mild stress. Medical students who failed in the final examination had higher psychological distress than those who passed the examination. Those who experienced high stress levels were more likely to fail than those who did not. Reducing the psychological distress of medical students prior to examination may help them to perform better in the examination.

Objectives: The demanding and intense environment of medical training can create excessive pressures on medical students that eventually lead to unfavorable consequences, either at a personal or professional level. These consequences can include poor academic performance and impaired cognitive ability. This study was designed to explore associations between pass-fail outcome and psychological health parameters (i.e. stress, anxiety, and depression symptoms). Methods: A cross-sectional study was conducted on a cohort of first-year medical students in a Malaysian medical school. The depression anxiety stress scale 21-item assessment (DASS-21) was administered to them right after the final paper of the first-year final examination. Their final examination outcomes (i.e. pass or fail) were traced by using their student identity code (ID) through the Universiti Sains Malaysia academic office. Results: A total of 194 (98.0%) of medical students responded to the DASS-21. An independent t-test showed that students who passed had significantly lower stress, anxiety, and depression symptoms than those who failed the first-year final examination (P <0.05). Those who experienced moderate to high stress were at 2.43 times higher risk for failing the examination than those who experienced normal to mild stress. Conclusion: Medical students who failed in the final examination had higher psychological distress than those who passed the examination. Those who experienced high stress levels were more likely to fail than those who did not. Reducing the psychological distress of medical students prior to examination may help them to perform better in the examination. PMID:23573390

Mexico has experienced changes in its demographic and epidemiologic profile accompanied by recent changes in nutrition and income. Thus, the old and the young have experienced very different environments. Using data from the Mexican National Health Nutrition Survey 2006, we examine age and sex differences in physiological status and dysregulation and assess how socioeconomic factors associate with variability in biological indicators of health. Results indicate that young people have experienced better physical development as evidenced by their being taller and having less stunting. There is currently little under-nutrition in Mexico, but there is evidence of over-nutrition as indicated by high prevalence of overweight across the age range. Physiological dysregulation across multiple systems is higher in Mexicans than Americans across all ages. Mexicans have: higher levels of blood pressure, plasma glucose, and especially for women, dysregulated cholesterol and higher body weight. Low education is associated with both being stunted and overweight, and with adverse levels of HDL cholesterol and more physiological risk factors. Rural dwelling males are less likely to be overweight as are females living in poor states. Living in a poor state among females and having rural residence among males is associated with a higher number of high-risk factors. Overweight is a strong predictor of hypertension. Age differences in indicators of physiological development suggest that the epidemiological and demographic transitions in Mexico were accompanied by improved physical development; however, increases in nutrition may have reached a point of diminishing returns as Mexico switched from a state of under-nutrition to over-nutrition.

Aboriginal peoples in Canada (First Nations, Metis and Inuit) are experiencing an epidemic of diabetes and its complications but little is known about the influence of factors attributed to colonization. The purpose of this study was to investigate the possible role of discrimination, residential school attendance and cultural disruption on diabetes occurrence among First Nations adults. This 2012/13 cross sectional survey was conducted in two Saskatchewan First Nations communities comprising 580 households and 1570 adults. In addition to self-reported diabetes, interviewer-administered questionnaires collected information on possible diabetes determinants including widely recognized (e.g. age, sex, lifestyle, social determinants) and colonization-related factors. Clustering effect within households was adjusted using Generalized Estimating Equations. Responses were obtained from 874 (55.7 %) men and women aged 18 and older living in 406 (70.0 %) households. Diabetes prevalence was 15.8 % among women and 9.7 % among men. In the final models, increasing age and adiposity were significant risk factors for diabetes (e.g. OR 8.72 [95 % CI 4.62; 16.46] for those 50+, and OR 8.97 [95 % CI 3.58; 22.52] for BMI 30+) as was spending most time on-reserve. Residential school attendance and cultural disruption were not predictive of diabetes at an individual level but those experiencing the most discrimination had a lower prevalence of diabetes compared to those who experienced little discrimination (2.4 % versus 13.6 %; OR 0.11 [95 % CI 0.02; 0.50]). Those experiencing the most discrimination were significantly more likely to be married and to have higher incomes. Known diabetes risk factors were important determinants of diabetes among First Nations people, but residential school attendance and cultural disruption were not predictive of diabetes on an individual level. In contrast, those experiencing the highest levels of discrimination had a low prevalence of diabetes. Although the reasons underlying this latter finding are unclear, it appears to relate to increased engagement with society off-reserve which may lead to an improvement in the social determinants of health. While this may have physical health benefits for First Nations people due to improved socio-economic status and other undefined influences, our findings suggest that this comes at a high emotional price.

Abstract As concerns about head impact in American football have grown, similar concerns have started to extend to other sports thought to experience less head impact, such as soccer and lacrosse. However, the amount of head impact experienced in soccer and lacrosse is relatively unknown, particularly compared with the substantial amount of data from football. This pilot study quantifies and compares head impact from four different types of sports teams: college football, high school football, college soccer, and college lacrosse. During the 2013 and 2014 seasons, 61 players wore mastoid patch accelerometers to quantify head impact during official athletic events (i.e., practices and games). In both practices and games, college football players experienced the most or second-most impacts per athletic event, highest average peak resultant linear and rotational acceleration per impact, and highest cumulative linear and rotational acceleration per athletic event. For average peak resultant linear and rotational acceleration per individual impact, college football was followed by high school football, then college lacrosse, and then college soccer, with similar trends in both practices and games. In the four teams under study, college football players experienced a categorically higher burden of head impact. However, for cumulative impact burden, the high school football cohort was not significantly different from the college soccer cohort. The results suggest that head impact in sport substantially varies by both the type of sport (football vs. soccer vs. lacrosse) and level of play (college vs. high school). PMID:27541183

The study analyzed differences in the risk of experiencing stressful life events (SLE) according to cultural factors, the level of economic development of the region inhabited, and gender. Information was gathered on the number and nature of SLE experienced by a sample of 604 undergraduates from 3 regions with very different levels of economic development: Madrid (Spain), León (Nicaragua), and Bilwi (Nicaragua). The results indicated a greater risk of experiencing SLE among undergraduates from Nicaragua, but few differences attributed to the undergraduates' gender or the level of economic development in the region they inhabit within the same country.

What Cortisol Can Tell us About the Costs of Sociality and Reproduction Among Free-Ranging Rhesus Macaque Females on Cayo Santiago

Research with the rhesus macaque population on Cayo Santiago can provide a unique perspective on the costs of sociality and reproduction in primates. Because the Cayo macaques live in unusually large groups and in a predator-free environment, in which their artificial food source lacks seasonal variation in abundance or quality, these monkeys constitute a semi-experimental study of the costs and benefits of group living. Here we review several long- and short-term studies that have focused on female life history and stress physiology. Long-term demographic data have shown that rhesus macaque females of middle- and low-ranking matrilines have lower adult survival probabilities than females of high-ranking matrilines. Costs of reproductive effort are also evident: adult females were more likely to die during the birth than during the mating season and they experienced higher cortisol levels when lactating. Lower-ranking females, in particular, experienced greater relative increase in cortisol production during lactation, in comparison to middle- and high-ranking females. Older high-ranking females had lower plasma cortisol levels than younger ones but cortisol levels were similarly high among young and old middle- and low-ranking females. Higher plasma cortisol levels and/or fecal glucocorticoid concentrations are associated with higher plasma concentrations of some proinflammatory cytokines. High cortisol, in turn, may be associated with chronic inflammation, and perhaps also with immunosuppression. In sum, the studies reviewed here provide multiple lines of evidence that sociality and reproductive effort impose measurable costs on female rhesus macaques. In line with socioecological theory, female dominance rank consistently emerges as an important modulator of variation in female life histories and physiology. The Cayo Santiago macaques are therefore a valuable model for elucidating the mechanisms by which within-group competition and reproduction impact health and survival in nonhuman primates and in humans.

It is important to know whether the relationships between experienced and evaluative well-being and health are consistent across countries with different income levels. This would allow to confirm whether the evidence found in high income countries is the same as in low- and middle-income countries and to suggest policy recommendations that are generalisable across countries. We assessed the association of well-being with health status; analysed the differential relationship that positive affect, negative affect, and evaluative well-being have with health status; and examined whether these relationships are similar across countries. In this cross-sectional study, interviews were conducted amongst 53,269 adults from nine countries in Africa, Asia, Europe, and Latin America. Evaluative well-being was measured with a short version of the World Health Organization (WHO) Quality of Life instrument, and experienced well-being was measured with the Day Reconstruction Method. Decrements in health were assessed with the 12-item version of WHO Disability Assessment Schedule 2.0. Block-wise linear regression and structural equation models were employed. Considering the overall sample, evaluative well-being was more strongly associated with health (β = -0.35) than experienced well-being (β = -0.14), and negative affect was more strongly associated with health (β = 0.10) than positive affect (β = -0.02). The relationship between health and well-being was similar across countries. Lower scores in evaluative well-being and a higher age were the factors more strongly related with a worse health. The different patterns observed across countries may be related to differences in the countries' gross domestic product, social protection system, economic situation, health care provision, lifestyle behaviours, or living conditions. The fact that evaluative well-being is more predictive of health than experienced well-being suggests that our level of satisfaction with our lives might be more important for our health than the actual emotions than we experience in our day-to-day lives and points out the need of interventions that improve the way people evaluate their lives.

This study aimed to examine the correlations between academic achievement and levels of anxiety and depression in medical students who were experiencing curriculum reform. The differences in academic achievement and the directions of correlations between academic achievement and anxiety and depression among the medical students with different levels of anxiety and depression were also examined. Grade 1 students from graduate-entry program and grade 3 students from undergraduate-entry program in their first semester of the new curriculum were recruited to complete the Zung's Anxiety and Depression Scale twice to examine their levels of anxiety and depression. Their academic achievement ratings in the four blocks of the first semester of the new curriculum were collected. The results indicated that no significant correlation was found between academic achievement and global anxiety and depression. However, by dividing the medical students into low, moderate and high level anxiety or depression groups, those who had poorer academic achievement in the first learning block were more likely to have higher levels of depression in the first psychologic assessment. Among the medical students who were in the high anxiety level group in the first psychologic assessment, those who had more severe anxiety had poorer academic achievement in the fourth learning block. Among the medical students who were in the low anxiety level group in the second psychologic assessment, those who had more severe anxiety had better academic achievement in the fourth learning block. Among the medical students who were in the moderate anxiety level group in the second psychologic assessment, those who had more severe anxiety had poorer academic achievement in the second learning block. Among the medical students who were in the high depression level group in the second psychologic assessment, those who had more severe depression had poorer academic achievement in the fourth learning block. The results of this study indicate that there are both positive and negative correlations between academic achievement and anxiety and depression in medical students, regarding differing levels of severity of anxiety or depression. The results could represent a reference for teachers on the planning of teaching and assessment programs.

2009-07-01

To determine whether measurement of soluble CD30 (sCD30) levels predicts for early rejection in a cohort of first deceased kidney transplant recipients. Pre-transplant serum samples were analysed for sCD30 levels using a commercial ELISA kit (Biotest). A 100 U/ml cut-off for "high sCD30" was applied. Clinical outcome parameters were biopsy-proven rejection episodes, creatinine levels and glomerular filtration rate. In the cohort of patients who experienced at least one episode of rejection in the first 6 months post-transplant, levels of pre-transplant sCD30 were significantly higher than in those who did not experience rejection. Despite this association, the occurrence of a high sCD30 level did not predict for rejection on an individual basis. The prognostic value of pre-transplant sCD30 testing is diminished by the large number of patients with high sCD30 levels who do not develop rejection. Although this limits the utility of the test in informing clinical management of individual patients, a high pre-transplant sCD30 level should still be considered a risk factor for poorer outcome.

Background Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC) has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training. Methods Among 361 young male aviators on active flight duty with experience in high performance aircrafts for at least 2 years, 350 had full data available and were reviewed in this study. We divided the aviators into the G-LOC group and the non-G-LOC group according to their human centrifuge training results. We then compared their basic characteristics, body composition, physical fitness level, and pulmonary function. Results Twenty nine aviators (8.3%) who experienced G-LOC during human centrifuge training in their first trials were classified into the G-LOC group. There was no difference in physical condition of aviators between the two groups. Conclusions Young aviators with experience in G-LOC showed no difference in physical condition such as muscle mass, strength, and general endurance from the aviators with no such experience. Although more studies are needed, physical condition does not seem to be a significant determinant of G-LOC among the experienced aviators. PMID:26812597

An exploratory survey measuring stigma and discrimination experienced by people living with HIV/AIDS in South Africa: the People Living with HIV Stigma Index

Background The continued presence of stigma and its persistence even in areas where HIV prevalence is high makes it an extraordinarily important, yet difficult, issue to eradicate. The study aimed to assess current and emerging HIV/AIDS stigma and discrimination trends in South Africa as experienced by people living with HIV/AIDS (PLHIV). Methods The PLHIV Stigma Index, a questionnaire that measures and detects changing trends in relation to stigma and discrimination experienced by PLHIV, was used as the survey tool. The study was conducted in 10 clinics in four provinces supported by the Foundation for Professional Development (FPD), with an interview total of 486 PLHIV. A cross-sectional design was implemented in the study, and both descriptive and inferential analysis was conducted on the data. Results Findings suggest that PLHIV in this population experience significant levels of stigma and discrimination that negatively impact on their health, working and family life, as well as their access to health services. Internalised stigma was prominent, with many participants blaming themselves for their status. Conclusion The findings can be used to develop and inform programmes and interventions to reduce stigma experienced by PLHIV. The current measures for dealing with stigma should be expanded to incorporate the issues related to health, education and discrimination experienced in the workplace, that were highlighted by the study.

Reduced funding to public health care systems during economic downturns is a common phenomenon around the world. The effect of health care cost on family members of the patients has not been established. This paper aims to explore the relationship between affordability of health care and vulnerability of family members to distress levels. Data of a total of 262,843 participants were obtained from 17 waves (1997-2013) of the United States National Health Interview Survey. Multinomial logistic regression was used to investigate psychological distress level as a result of having family members who experienced unmet medical needs due to cost. Among participants without family members who experienced unmet needs for medical care due to cost, risks of having 'moderate' (score of 5-12) or 'serious' (score of 13 or above) level of psychological distress were 1.0% and 11.5%, respectively. Risks of having 'moderate' or 'serious' level of psychological distress were 3.1% and 23.4%, respectively among participants with family members who experienced unmet needs. The adjusted relative risk ratio of 'moderate' and 'serious', as compared to 'normal' level of psychological distress, were 1.58 (95% confidence interval: 1.47-1.69) and 2.09 (95% confidence interval: 1.78-2.45) if one's family members experienced unmet medical needs. Unmet medical needs due to cost increases risk of distress levels experienced by family members. Careful planning and adequate funding to public health care system could be implemented to prevent any unnecessary detrimental effect on mental health among family members of the unwell and any further increment of the prevalence of mental illnesses. This recommendation aligns with the World Health Organization Mental Health Action Plan 2013-2020.

Although psychological factors are widely considered to be important in atopic eczema, there have been few controlled studies to assess the extent of disturbance in affected children and the problems experienced by their parents. This study was designed to find out the degree of psychological difficulty experienced by children with atopic eczema, whether their mothers show higher levels of mental distress than a comparison group, and whether the families of children with atopic eczema have less social support than the comparison group. We investigated 30 school-aged children with atopic eczema for psychological problems using the Rutter parent scale and compared them with 30 children with relatively minor skin lesions such as viral warts. Mental distress in mothers was assessed using the General Health Questionnaire. The Family Support Scale was used to get a measure of the social support experienced by the families. We found twice the rate of psychological disturbance in children in the eczema group compared with the control group. This difference was statistically significant for children with moderately severe eczema and severe eczema, but not for children with very mild eczema. Levels of mental distress were no greater in mothers of children with eczema than in parents of the control group and there was no difference in the degree of social support experienced by their families. These findings indicate that school-aged children with moderate and severe atopic eczema are at high risk of developing psychological difficulties, which may have implications for their academic and social development.

Developing a compassionate mind to enhance trauma-focused CBT with an adolescent female: a case study.

Shame and disgust are often associated with posttraumatic stress disorder (PTSD) following interpersonal traumas such as sexual assault. It has been suggested that individuals with high levels of shame might do less well in standard cognitive behavioural (CBT) interventions. To see whether applying compassion-focused therapy and developing a compassionate mind can enhance trauma-focused CBT in an adolescent with high levels of shame and disgust the way it has been shown to within the adult population. This single case study describes how trauma-focused CBT was enhanced by compassionate mind training. It details work using this approach with an adolescent female experiencing shame and disgust-based flashbacks. Treatment was provided for 20 sessions over 8 months. Symptoms of PTSD, depression and self-criticism, as well as the ability to self-soothe/reassure, were measured at assessment/start of treatment, mid- and end of treatment. Clinically significant reductions in PTSD, depressive, shame and self-attacking symptoms were found between assessment and completion of treatment. Clinically significant increases in self-reassurance were also reported. Following treatment, symptoms of PTSD and depression were sub-clinical. This case study suggests that developing a compassionate mind alongside trauma-focused CBT may be beneficial to adolescents experiencing shame and disgust with consideration for the young person's level of development and personal circumstances.

Patients experiencing homelessness represent a disproportionate share of emergency department (ED) visits due to poor access to primary care and high levels of unmet health care needs. This is in part due to the difficulty of communicating and following up with patients who are experiencing homelessness. To determine the prevalence and types of "new media" use among ED patients who experience homelessness. This was a cross-sectional observational study with sequential enrolling of patients from three emergency departments 24/7 for 6 weeks. In total, 5788 ED patients were enrolled, of whom 249 experienced homelessness. Analyses included descriptive statistics, and unadjusted and adjusted odds ratios. 70.7% (176/249) of patients experiencing homelessness own cell phones compared to 85.90% (4758/5539) of patients in stable housing (P=.001) with the former more likely to own Androids, 70% (53/76) versus 43.89% (1064/2424), and the latter more likely to have iPhones, 44.55% (1080/2424) versus 17% (13/76) (P=.001). There is no significant difference in new media use, modality, or frequency for both groups; however, there is a difference in contract plan with 50.02% (2380/4758) of stably housed patients having unlimited minutes versus 37.5% (66/176) of homeless patients. 19.78% (941/4758) of patients in stable housing have pay-as-you-go plans versus 33.0% (58/176) of homeless patients (P=.001). Patients experiencing homelessness are more likely to want health information on alcohol/substance abuse, mental health, domestic violence, pregnancy and smoking cessation. This study is unique in its characterization of new media ownership and use among ED patients experiencing homelessness. New media is a powerful tool to connect patients experiencing homelessness to health care.

Lundberg, U; Frankenhaeuser, M

1999-04-01

Psychological and physiological stress responses related to work and family were investigated in 21 female and 21 male managers and professional specialists in high-ranking positions. The main result was that both women and men experienced their jobs as challenging and stimulating, although almost all data indicated a more favorable situation for men than for women. In addition, women were more stressed by their greater unpaid workload and by a greater responsibility for duties related to home and family. Women had higher norepinephrine levels than men did, both during and after work, which reflected their greater workload. Women with children at home had significantly higher norepinephrine levels after work than did the other participants. The possible long-term health consequences of women's higher stress levels are discussed.

The allostasis theory postulates that stress causes the body to activate physiologic systems in order to maintain stability. The authors sought to examine the relationship between earlier stress and later development of breast cancer (BC). Authors correlated discrete and interactive relationships of stressful life events, social support, and well-being during childhood and adolescence with the occurrence of BC in adulthood among 300 women with primary BC and 305 matched control subjects. BC patients and control subjects reported similar childhood experiences. Yet, although childhood stressful life events were associated with reports of less family support and well being among the controls, those in the BC group who experienced high stress in early childhood actually expressed higher levels of family support and well-being than did those who had experienced lower levels of stress. These findings may reflect a tendency toward a repressive coping style among the BC group, which may be either a risk factor for the disease or a result of having it.

The Likelihood of Experiencing Relative Poverty over the Life Course

Research on poverty in the United States has largely consisted of examining cross-sectional levels of absolute poverty. In this analysis, we focus on understanding relative poverty within a life course context. Specifically, we analyze the likelihood of individuals falling below the 20th percentile and the 10th percentile of the income distribution between the ages of 25 and 60. A series of life tables are constructed using the nationally representative Panel Study of Income Dynamics data set. This includes panel data from 1968 through 2011. Results indicate that the prevalence of relative poverty is quite high. Consequently, between the ages of 25 to 60, 61.8 percent of the population will experience a year below the 20th percentile, and 42.1 percent will experience a year below the 10th percentile. Characteristics associated with experiencing these levels of poverty include those who are younger, nonwhite, female, not married, with 12 years or less of education, or who have a work disability.

The nature and structure of the school environment has the potential to shape children's health and well being. Few studies have explored the importance of school-level factors in explaining a child's likelihood of experiencing violence from school staff, particularly in low-resource settings such as Uganda. To quantify to what extent a student's risk of violence is determined by school-level factors we fitted multilevel logistic regression models to investigate associations and present between-school variance partition coefficients. School structural factors, academic and supportive environment are explored. 53% of students reported physical violence from staff. Only 6% of variation in students' experience of violence was due to differences between schools and half the variation was explained by the school-level factors modelled. Schools with a higher proportion of girls are associated with increased odds of physical violence from staff. Students in schools with a high level of student perceptions of school connectedness have a 36% reduced odds of experiencing physical violence from staff, but no other school-level factor was significantly associated. Our findings suggest that physical violence by school staff is widespread across different types of schools in this setting, but interventions that improve students' school connectedness should be considered. © The Author 2015.

We report 2 patients with dry eye disease followed up using the expression levels of ocular surface mucin. Patient 1: a 57-year-old woman with Sjögren's syndrome-associated dry eyes experienced severe dryness and foreign body sensation in both her eyes, and instilled sodium hyaluronate ophthalmic solution 0.3% about 10-15 times daily. We measured the expression levels of MUC5AC mRNA (MUC5AC) and MUC16 mRNA (MUC16) by using real-time reversed transcription polymerase chain reaction for the specimens of modified impression cytology. Expression levels of MUC5AC and MUC16 on her ocular surface were very low. Subjective symptoms and expression levels of ocular surface mucin improved after combined treatment of rebamipide (4 times daily) and fluorometholone (once daily) ophthalmic suspension. Patient 2: a 62-year-old man with chronic graft-versus-host disease-associated dry eye experienced severe foreign body sensation and developed superficial punctate keratopathy with mucous thread and filamentary keratitis. Expression level of MUC5AC was very high at baseline. Subjective symptoms and expression levels of ocular surface mucin improved by combined treatment of rebamipide (4 times daily) and fluorometholone (once daily) ophthalmic suspension. Clinical test for MUC gene expression on the ocular surface was found to be useful in the follow-up of dry eye treatment.

The substantial number of young people in romantic relationships that involve intimate partner violence, a situation deleterious to physical and mental health, has resulted in increased attention to understanding the links between risk factors and course of violence. The current study examined couples' interpersonal stress related to not liking partners' friends and not getting along with parents as contextual factors associated with couples' psychological partner violence and determined whether and when couples' friend and parent stress increased the likelihood of couples' psychological partner violence. A linear latent growth curve modeling approach was used with multiwave measures of psychological partner violence, friend stress, parent stress, and relationship satisfaction obtained from 196 men at risk for delinquency and their women partners over a 12-year period. At the initial assessment, on average, the men were age 21.5 years and the women were age 21 years. Findings indicated that couples experiencing high levels of friend and parent stress were more likely to engage in high levels of psychological partner violence and that increases in couples' friend stress predicted increases in couples' partner violence over time, even when accounting for the couples' relationship satisfaction, marital status, children in the home, and financial strain. Interactive effects were at play when the couples were in their early 20s, with couples being most at risk for increases in psychological partner violence if they experienced both high friend stress and low relationship satisfaction. Couples' friend stress had the greatest effect on psychological partner violence when the couples were in their early to mid 20s when levels of friend stress were high. As the couples reached their 30s, low relationship satisfaction became the leading predictor of couples' psychological partner violence.

In neurosurgery education, there is a paradigm shift from time-based training to criterion-based model for which competency and assessment becomes very critical. Even virtual reality simulators provide alternatives to improve education and assessment in neurosurgery programs and allow for several objective assessment measures, there are not many tools for assessing the overall performance of trainees. This study aims to develop and validate a tool for assessing the overall performance of participants in a simulation-based endoneurosurgery training environment. A training program was developed in two levels: endoscopy practice and beginning surgical practice based on four scenarios. Then, three experiments were conducted with three corresponding groups of participants (Experiment 1, 45 (32 beginners, 13 experienced), Experiment 2, 53 (40 beginners, 13 experienced), and Experiment 3, 26 (14 novices, 12 intermediate) participants). The results analyzed to understand the common factors among the performance measurements of these experiments. Then, a factor capable of assessing the overall skill levels of surgical residents was extracted. Afterwards, the proposed measure was tested to estimate the experience levels of the participants. Finally, the level of realism of these educational scenarios was assessed. The factor formed by time, distance, and accuracy on simulated tasks provided an overall performance indicator. The prediction correctness was very high for the beginners than the one for experienced surgeons in Experiments 1 and 2. When non-dominant hand is used in a surgical procedure-based scenario, skill levels of surgeons can be better predicted. The results indicate that the scenarios in Experiments 1 and 2 can be used as an assessment tool for the beginners, and scenario-2 in Experiment 3 can be used as an assessment tool for intermediate and novice levels. It can be concluded that forming the balance between perceived action capacities and skills is critical for better designing and developing skill assessment surgical simulation tools.

In the last three decades, China has experienced rapid economic development and growing economic inequality, such that economic disparities between rural and urban areas, as well as coastal and interior areas have deepened. Since the late 1990s China has also experienced an ageing population which has attracted attention to the wellbeing of the rapidly growing number of elderly. This research aims to characterise province differences in health and to explore the effects of individual income and economic disparity in the form of income inequality on health outcomes of the elderly. The study is based on the Chinese Longitudinal Healthy Longevity Survey data collected in 2008 for 23 provinces. Multilevel logistic models are employed to investigate the relationship between income, income inequality and self-rated health for the elderly using both individual and province-level variables. Results are presented as relative odds ratios, and for province differentials as Median Odds Ratios. The analysis is deliberately exploratory so as to find evidence of income effects if they exist and particular attention is placed on how province-level inequality (contemporaneous and lagged) may moderate individual relationships. The results show that the health of the elderly is not only affected by individual income (the odds of poor health are 3 times greater for the elderly with the lowest income compared to those at the upper quartile) but also by a small main effect for province-level income inequality (odds ratio of 1.019). There are significant cross-level interactions such that where inequality is high there are greater differences between those with and without formal education, and between men and women with the latter experiencing poorer health.

A cross-sectional study targeted a total of 43,630 pupils in Niigata City, Japan was performed. The objective was to clarify the present incidence of low back pain (LBP) in childhood and adolescence in Japan. It has recently been recognized that LBP in childhood and adolescence is also as common a problem as that for adults and most of these studies have been conducted in Europe, however, none have so far been made in Japan. A questionnaire survey was conducted using 43,630 pupils, including all elementary school students from the fourth to sixth grade (21,893 pupils) and all junior high students from the first to third year (21,737 pupils) in Niigata City (population of 785,067) to examine the point prevalence of LBP, the lifetime prevalence, the gender differences, the age of first onset of LBP in third year of junior high school students, the duration, the presence of recurrent LBP or not, the trigger of LBP, and the influences of sports and physical activities. In addition, the severity of LBP was divided into three levels (level 1: no limitation in any activity; level 2: necessary to refrain from participating in sports and physical activities, and level 3: necessary to be absent from school) in order to examine the factors that contribute to severe LBP. The validity rate was 79.8% and the valid response rate was 98.8%. The point prevalence was 10.2% (52.3% male and 47.7% female) and the lifetime prevalence was 28.8% (48.5% male and 51.5% female). Both increased as the grade level increased and in third year of junior high school students, a point prevalence was seen in 15.2% while a lifetime prevalence was observed in 42.5%. About 90% of these students experienced first-time LBP during the first and third year of junior high school. Regarding the duration of LBP, 66.7% experienced it for less than 1 week, while 86.1% suffered from it for less than 1 month. The recurrence rate was 60.5%. Regarding the triggers of LBP, 23.7% of them reported the influence of sports and exercise such as club activities and physical education, 13.5% reported trauma, while 55.6% reported no specific triggers associated with their LBP. The severity of LBP included 81.9% at level 1, 13.9% at level 2 and 4.2% at level 3. It was revealed that LBP in childhood and adolescence is also a common complaint in Japan, and these findings are similar to previous studies conducted in Europe. LBP increased as the grade level increased and it appeared that the point and lifetime prevalence in adolescence are close to the same levels as those seen in the adulthood and there was a tendency to have more severe LBP in both cases who experienced pain for more than 1 month and those with recurrent LBP.

High activity noise levels that result in detrimental effects on speech communication have been measured in preschools. To find out if different pedagogical ideologies affect the perceived loudness and levels of noise, a questionnaire study inquiring about the experience of loudness and voice symptoms was carried out in Iceland in eight private preschools, called "Hjalli model", and in six public preschools. Noise levels were also measured in the preschools. Background variables (stress level, age, length of working career, education, smoking, and number of children per teacher) were also analyzed in order to determine how much they contributed toward voice symptoms and the experience of noisiness. Results indicate that pedagogical ideology is a significant factor for predicting noise and its consequences. Teachers in the preschool with tighter pedagogical control of discipline (the "Hjalli model") experienced lower activity noise loudness than teachers in the preschool with a more relaxed control of behavior (public preschool). Lower noise levels were also measured in the "Hjalli model" preschool and fewer "Hjalli model" teachers reported voice symptoms. Public preschool teachers experienced more stress than "Hjalli model" teachers and the stress level was, indeed, the background variable that best explained the voice symptoms and the teacher's perception of a noisy environment. Discipline, structure, and organization in the type of activity predicted the activity noise level better than the number of children in the group. Results indicate that pedagogical ideology is a significant factor for predicting self-reported noise and its consequences.

You may worry, but can you recognize threats when you see them?; Neuroticism, threat identifications, and negative affect.

PubMed

Tamir, Maya; Robinson, Michael D; Solberg, Emily Crawford

2006-10-01

The present studies sought to investigate the hedonic consequences of threat-identification skills at low and high levels of neuroticism. Such skills were assessed in terms of both speed (Study 1) and accuracy (Study 2) of identifying threatening objects in cognitive tasks. As predicted, threat-identification skills interacted with trait neuroticism in predicting subjective experiences. Specifically, individuals high in neuroticism experienced lower levels of negative affect during their everyday lives if they were also skilled in identifying threats in the cognitive tasks (Studies 1-2). Such skills did not matter at low levels of neuroticism. This interactive pattern was also replicated in the context of life domain satisfaction (Study 2). The results support the view that avoidance motivation encompasses multiple component processes, including some that are cognitive in nature, and specifically extends self-regulatory views of neuroticism. Of most importance, our data indicate that threat-identification skills can be hedonically beneficial, rather than costly, at high levels of neuroticism.

Subseasonal to Seasonal Predictions of U.S. West Coast High Water Levels

NASA Astrophysics Data System (ADS)

Khouakhi, A.; Villarini, G.; Zhang, W.; Slater, L. J.

Extreme sea levels pose a significant threat to coastal communities, ecosystems, and assets, as they are conducive to coastal flooding, coastal erosion and inland salt-water intrusion. As sea levels continue to rise, these sea level extremes - including occasional minor coastal flooding experienced during high tide (nuisance floods) - are of concern. Extreme sea levels are increasing at many locations around the globe and have been attributed largely to rising mean sea levels associated with intra-seasonal to interannual climate processes such as the El Niño-Southern Oscillation (ENSO). Here, intra-seasonal to seasonal probabilistic forecasts of high water levels are computed at the Toke Point tide gage station on the US west coast. We first identify the main climate drivers that are responsible for high water levels and examine their predictability using General Circulation Models (GCMs) from the North American Multi-Model Ensemble (NMME). These drivers are then used to develop a probabilistic framework for the seasonal forecasting of high water levels. We focus on the climate controls on the frequency of high water levels using the number of exceedances above the 99.5th percentile and above the nuisance flood level established by the National Weather Service. Our findings indicate good forecast skill at the shortest lead time, with the skill that decreases as we increase the lead time. In general, these models aptly capture the year-to-year variability in the observational records.

Weight-related stigma is a significant psychosocial stressor in developing countries: Evidence from Guatemala.

PubMed

Hackman, Joseph; Maupin, Jonathan; Brewis, Alexandra A

2016-07-01

Weight-related stigma is established as a major psychosocial stressor and correlate of depression among people living with obesity in high-income countries. Anti-fat beliefs are rapidly globalizing. The goal of the study is to (1) examine how weight-related stigma, enacted as teasing, is evident among women from a lower-income country and (2) test if such weight-related stigma contributes to depressive symptoms. Modeling data for 12,074 reproductive-age women collected in the 2008-2009 Guatemala National Maternal-Infant Health Survey, we demonstrate that weight-related teasing is (1) experienced by those both underweight and overweight, and (2) a significant psychosocial stressor. Effects are comparable to other factors known to influence women's depressive risk in lower-income countries, such as living in poverty, experiencing food insecurity, or suffering sexual/domestic violence. That women's failure to meet local body norms-whether they are overweight or underweight-serves as such a strong source of psychological distress is particularly concerning in settings like Guatemala where high levels of over- and under-nutrition intersect at the household and community level. Current obesity-centric models of weight-related stigma, developed from studies in high-income countries, fail to recognize that being underweight may create similar forms of psychosocial distress in low-income countries.

2017-05-01

For older adults coping with a spouse's chronic condition, greater marital satisfaction may not be entirely protective for psychological health. We examined marital satisfaction and gender as moderators of the association between perceived spousal suffering and daily emotional contagion. Based on empathy-altruism and interdependent self-construal theories, we hypothesized that high marital satisfaction and being female would heighten daily emotional contagion, or within-person associations between perceived spouse suffering and distress to spouse suffering. Forty-five older adults who had a spouse with a musculoskeletal condition completed daily interviews. Participants reported their marital satisfaction once in the laboratory and then daily perceptions of their spouse's physical suffering and their own distress to spouse suffering via phone at home for 7 days. Consistent with hypotheses, there were significant within-person effects such that highly satisfied wives experienced heightened emotional contagion on days when they perceived higher than average spouse suffering. Unexpectedly, men who were high in marital satisfaction experienced heightened daily distress irrespective of their perceptions of level of spousal suffering. Marital satisfaction can increase daily emotional contagion to spousal suffering among older couples dealing with chronic conditions. Wives' distress may be more dependent on perceiving high levels of partner suffering compared with husbands' distress. © The Author 2015.

Town, Joel M; Hardy, Gillian E; McCullough, Leigh; Stride, Chris

2012-01-01

The aim of this research was to examine the relationship between therapist interventions and patient affect responses in Short-Term Dynamic Psychotherapy (STDP). The Affect Experiencing subscale from the Achievement of Therapeutic Objectives Scale (ATOS) was adapted to measure individual immediate affect experiencing (I-AES) responses in relation to therapist interventions coded within the preceding speaking turn, using the Psychotherapy Interaction Coding (PIC) system. A hierarchical linear modelling procedure was used to assess the change in affect experiencing and the relationship between affect experiencing and therapist interventions within and across segments of therapy. Process data was taken from six STDP cases; in total 24 hours of video-taped sessions were examined. Therapist interventions were found to account for a statistically significant amount of variance in immediate affect experiencing. Higher levels of immediate affect experiencing followed the therapist's use of Confrontation, Clarification and Support compared to Questions, Self-disclosure and Information interventions. Therapist Confrontation interventions that attempted to direct pressure towards either the visceral experience of affect or a patient's defences against feelings led to the highest levels of immediate affect experiencing. The type of therapist intervention accounts for a small but significant amount of the variation observed in a patient's immediate emotional arousal. Empirical findings support clinical theory in STDP that suggests strategic verbal responses promote the achievement of this specific therapeutic objective.

The costs and benefits of getting the ISO 9000 certification in the manufacturing sector in Saudi Arabia.

Many Saudi companies, in their journey to improve quality, efficiency and competitiveness, are pursuing and obtaining the ISO 9000 certificate. Many studies have evaluated how to implement ISO 9000 in different sectors, but none have analyzed the effectiveness of ISO 9000 certification (costs and benefits) on improving the overall quality and on meeting expectations. This study addressed these issues by investigating manufacturing organizations in Saudi Arabia that have the ISO 9000 certification. A survey questionnaire was distributed to firms throughout the kingdom. Thirty-two firms participated in the study. Results indicate that increased consistency of operations, improved service, and product quality are among the top motivators for pursuing the ISO certificate. The benefits most often experienced were improved awareness of procedural problems, better management control, keeping existing customers, increased customer satisfaction, and improved customer service. Difficulties experienced during the certification process involved time and cost, but these were not considered to be major problems. A high volume of paperwork was the main problem experienced following initial certification. Respondents in general said that the ISO 9000 certification met their expectations and that their level of satisfaction regarding the impact of ISO 9000 was high. Most recommended that other organizations pursue the certificate.

Community pharmacy-based asthma services--what do patients prefer?

Patient preferences can influence the outcomes of treatment and so understanding and organizing health-care services around these preferences is vital. To explore patient preferences for types of community pharmacy-based asthma services, to investigate the influence of "experience" in molding preferences for such services, and to identify aspects of the services that patients prefer over others. Semistructured face-to-face interviews were conducted with a convenience sample of two types of asthma patients: (1) those naïve to a specialized asthma service and (2) those who had experienced a specialized asthma service. Interviews were audio-recorded, transcribed verbatim, and thematically analyzed. Eighteen interviews were conducted (8 experienced patients, 10 naïve patients). The majority of the patients wanted the pharmacist to play a greater role in their asthma management. Patients experiencing increased levels of service had increased levels of expectations as well as more specific preferences for various aspects of the service. The key aspects of an asthma service that all patients wanted their pharmacists to provide were the provision of information about asthma and its medications, lung function testing and monitoring of their asthma, and checking/correcting their inhaler technique. Patients also expressed a desire for skilled communication and behavioral aspects from the pharmacist such as friendliness, empathy, attentiveness, and dedicated time. Patients highlighted the importance of privacy in the pharmacy. There was a high level of satisfaction toward the currently delivered asthma service among both naïve and experienced patients. The provision of the specialized service was associated with increased patient loyalty to the particular pharmacy. All patients indicated a willingness to participate in future pharmacy-delivered specialized asthma services. Elements of the specialized pharmacy-based asthma services important from a patient's perspective were identified. It would be important to identify the strength and magnitude of patient's preferences for different elements of such services. Future pharmacy-based services should incorporate patient preferences and tailor services to patient's needs to ensure their long-term viability.

Health care organizations globally realize the need to address physician burnout due to its close linkages with quality of care, retention and migration. The many functions of health human resources include identifying and managing burnout risk factors for health professionals, while also promoting effective coping. Our study of physician burnout aims to show: (1) which correlates are most strongly associated with emotional exhaustion (EE) and depersonalization (DP), and (2) whether the associations vary across regions and specialties. Meta-analysis allowed us to examine a diverse range of correlates. Our search yielded 65 samples of physicians from various regions and specialties. EE was negatively associated with autonomy, positive work attitudes, and quality and safety culture. It was positively associated with workload, constraining organizational structure, incivility/conflicts/violence, low quality and safety standards, negative work attitudes, work-life conflict, and contributors to poor mental health. We found a similar but weaker pattern of associations for DP.Physicians in the Americas experienced lower EE levels than physicians in Europe when quality and safety culture and career development opportunities were both strong, and when they used problem-focused coping. The former experienced higher EE levels when work-life conflict was strong and they used ineffective coping. Physicians in Europe experienced lower EE levels than physicians in the Americas with positive work attitudes. We found a similar but weaker pattern of associations for DP.Outpatient specialties experienced higher EE levels than inpatient specialties when organization structures were constraining and contributors to poor mental health were present. The former experienced lower EE levels when autonomy was present. Inpatient specialties experienced lower EE levels than outpatient specialties with positive work attitudes. As above, we found a similar but weaker pattern of associations for DP. Although we could not infer causality, our findings suggest: (1) that EE represents the core burnout dimension; (2) that certain individual and organizational-level correlates are associated with reduced physician burnout; (3) the benefits of directing resources where they are most needed to physicians of different regions and specialties; and (4) a call for research to link physician burnout with performance.

BACKGROUND: Although infliximab is an effective therapy for inflammatory bowel disease (IBD), it is associated with dermatological events and infusion reactions. It is not known whether a relationship between these adverse events (AEs) and infliximab trough levels (ITLs) exists. OBJECTIVES: To report the prevalence of infliximab-associated AEs in IBD patients receiving stable maintenance infliximab therapy, and to correlate ITLs with dermatological and infusion reactions to infliximab. METHODS: Adult IBD patients receiving stable maintenance infliximab therapy were recruited from the University of Alberta Infusion Clinic (Edmonton, Alberta). ITLs were measured in blood samples collected before infusion, and the patients’ records were reviewed for dermatological and infusion reactions to infliximab. RESULTS: One-quarter (18 of 71 [25.4%]) of patients experienced dermatological or infusion reactions to infliximab: nine (12.7%) dermatological events and nine (12.7%) infusion reactions. The median ITL was similar among patients with and without these AEs (7.2 μg/mL [interquartile range (IQR) 2.0 μg/mL to 13.3 μg/mL] versus 6.6 μg/mL [IQR 3.2 μg/mL to 12.7 μg/mL]; P=0.648). The median ITL of patients who experienced infusion reactions (2.0 μg/mL [IQR 0.1 μg/mL to 5.7 μg/mL]) was lower than that of patients who experienced no such AEs (6.6 μg/mL [IQR 3.2 μg/mL to 12.7 μg/mL]; P=0.008]) and lower than that of patients who experienced dermatological AEs (13.3 μg/mL [IQR 8.8 μg/mL to 17.4 μg/mL]; P<0.001). CONCLUSION: One-quarter of IBD outpatients receiving stable maintenance infliximab therapy experienced dermatological and infusion reactions. Low ITLs were correlated with infusion reactions, and normal or high ITLs with dermatological events. PMID:25706572

Female orgasmic experience: a subjective study.

Human female orgasm was studied by collecting and analyzing the subjective orgasmic histories of 30 women, ages 18 to 59 years. Virtually all of the 93% who reported they had experienced orgasm also reported some level of conscious control over whether or not they reached orgasm. Women differed widely as to preferred types of physical stimulation and/or mental activities to facilitate orgasm. Orgasms were experienced as centered in the clitoral and/or vaginal areas. Women over 40 were more likely to have experienced orgasm in more than one anatomic site than were women aged 18 to 29. Marital status, religion, occupation, educational level, experiences of pregnancy and childbirth, various reported characteristics of relationships with partners, and early sexual experience were not associated with where orgasm is experienced within the body or with other variables of adult orgasmic experience. The variation among women as to how orgasm is best reached, differences in where it is experienced within the body, and the reasons why an individual woman experiences orgasms differently over time remain poorly understood phenomena.

Health and social care services are increasingly reliant on informal caregivers to provide long-term support to stroke survivors. However, caregiving is associated with elevated levels of depression and anxiety in the caregiver that may also negatively impact stroke survivor recovery. This qualitative study aims to understand the specific difficulties experienced by caregivers experiencing elevated symptoms of anxiety and depression. Nineteen semi-structured interviews were conducted with caregivers experiencing elevated levels of depression and anxiety, with a thematic analysis approach adopted for analysis. Analysis revealed three main themes: Difficulties adapting to the caring role; Uncertainty; and Lack of support. Caregivers experienced significant difficulties adapting to changes and losses associated with becoming a caregiver, such as giving up roles and goals of importance and value. Such difficulties persisted into the long-term and were coupled with feelings of hopelessness and worry. Difficulties were further exacerbated by social isolation, lack of information and poor long-term health and social care support. A greater understanding of difficulties experienced by depressed and anxious caregivers may inform the development of psychological support targeting difficulties unique to the caring role. Improving caregiver mental health may also result in health benefits for stroke survivors themselves.

Although anti-bullying interventions are often effective, some children continue to be victimized. To increase knowledge of potential factors that might impede children's benefiting from an anti-bullying intervention, we examined potential reasons for individual differences in victimization trajectories during a group-based anti-bullying intervention. Data stem from a five-wave survey among 9122 children (7-12 years old; grades 2-5) who participated in the KiVa anti-bullying intervention (n = 6142) or were in control schools (n = 2980 children). Three trajectories were found in the intervention sample, representing children who experienced stable high, decreasing, or stable low/no victimization. A two-trajectory model of high and low trajectories represented the control sample best. Multinomial regressions on the intervention sample showed that children who experienced particularly high levels of peer rejection, internalizing problems, and lower quality parent-child relationships decreased less in victimization; thus these characteristics appeared to contribute to persistent victimization. The results call for tailored strategies in interventions aiming to reduce victimization for more children.

Fatigue is one of the most commonly reported symptoms of multiple sclerosis (MS). It has a profound impact on all spheres of life, for people with MS and their relatives. It is one of the key precipitants of early retirement. Individual, group, and Internet cognitive behavioral therapy-based approaches to supporting people with MS to manage their fatigue have been shown to be effective. The aim of this project was to (1) survey the types of mobile devices and level of Internet access people with MS use or would consider using for a health intervention and (2) characterize the levels of fatigue severity and their impact experienced by the people in our sample to provide an estimate of fatigue severity of people with MS in New Zealand. The ultimate goal of this work was to support the future development of a mobile intervention for the management of fatigue for people with MS. Survey methodology using an online questionnaire was used to assess people with MS. A total of 51 people with MS participated. The average age was 48.5 years, and the large majority of the sample (77%) was female. Participants reported significant levels of fatigue as measured with the summary score of the Neurological Fatigue Index (mean 31.4 [SD 5.3]). Most (84%) respondents scored on average more than 3 on the fatigue severity questions, reflecting significant fatigue. Mobile phone usage was high with 86% of respondents reporting having a mobile phone; apps were used by 75% of respondents. Most participants (92%) accessed the Internet from home. New Zealand respondents with MS experienced high levels of both fatigue severity and fatigue impact. The majority of participants have a mobile device and access to the Internet. These findings, along with limited access to face-to-face cognitive behavioral therapy-based interventions, create an opportunity to develop a mobile technology platform for delivering a cognitive behavioral therapy-based intervention to decrease the severity and impact of fatigue in people with MS. ©Kirsten Van Kessel, Duncan R Babbage, Nicholas Reay, Warren M Miner-Williams, Paula Kersten.

Enriched environment at work (EEW), in terms of high mental demands at work, may be of great relevance for preventative efforts against cognitive decline and dementia as previous studies have shown. Yet, there is the concern that high EEW mental demands may accelerate stress and cause burnout. The aim of our study was to investigate how EEW mental demands are related to stress and burnout. A convenience sample of employees in the city area of Leipzig, Germany, was asked to fill out the Copenhagen Burnout Inventory and indicate for each EEW mental demand the level experienced, demandingness, and stressfulness. Multivariate linear regression and structural equation modelling suggested that only some EEW mental demands were perceived as stressful when the level of the respective EEW mental demand was high. Higher stressfulness was associated with burnout symptoms - however, high levels of EEW mental demands were not significantly associated with burnout (neither directly nor indirectly). Our findings implied that subjectively perceived stressfulness seems to be a more relevant aspect than the actual level of the demand itself. However, further studies are necessary to validate our findings.

Responsibility is a necessary prerequisite in the experience of regret. The present fMRI study investigated the modulation of responsibility on the neural correlates of regret during a sequential risk-taking task. Participants were asked to open a series of boxes consecutively and decided when to stop. Each box contained a reward, except for one containing a devil to zero participant's gain in the trial. Once participants stopped, both collected gains and missed chances were revealed. We manipulated responsibility by setting two different contexts. In the Self (high responsibility) context, participants opened boxes and decided when to stop by themselves. In the Computer (low responsibility) context, a computer program opened boxes and decided when to stop for participants. Before each trial, participants were required to decide whether it would be a Self or a Computer context. Behaviorally, participants felt less regret (more relief) for gain outcome and more regret for the loss outcome in the high-responsibility context than low responsibility context. At the neural level, when experiencing a gain, high-responsibility trials were characterized by stronger activation in mPFC, pgACC, mOFC, and striatum with decreasing number of missed chances relative to low responsibility trials. When experiencing a loss, low responsibility trials were associated with stronger activation in dACC and bilateral insula than high-responsibility trials. Conversely, during a loss, high-responsibility trials showed more striatum activity than low responsibility trials. These results highlighted the sensitivity of the frontal region, striatum, and insula to changes in level of responsibility.

To examine the relation between current alcohol use, estradiol, estrone, and testosterone levels, and hot flashes in midlife women using a case-control study design. Cases were midlife women (45-54 years) who reported ever experiencing hot flashes. Controls were midlife women (45-54 years) who reported never experiencing hot flashes. Each participant completed a questionnaire and provided a blood sample that was used to measure estradiol, estrone, and testosterone levels by enzyme-linked immunosorbent assay. The results indicate that current alcohol use (at least one day per month) was significantly associated with a reduced risk of hot flashes compared to non-use of alcohol, independent of age and smoking habits. The hot flashes experienced by current alcohol users were less severe and less frequent than those experienced by non-users of alcohol. Further, current alcohol users had similar levels of estradiol, estrone, and testosterone compared to non-users of alcohol. These data suggest that current alcohol use is associated with a reduced risk of any, severe, and frequent hot flashes in midlife women by a mechanism that may not include changes in sex steroid hormone levels.

Is there an emotional cost of completing high school? Ecological factors and psychological distress among LGBT homeless youth.

This study explored the nexus of home and school climate on the psychological distress of lesbian, gay, bisexual, and transgender (LGBT) homeless youth, as well as their experiences during high school. Of the LGBT homeless youth (N = 89) surveyed, 39.3% reported not completing high school. Most participants did not seek support from school staff nor did they report attending a school with a Gay-Straight Alliance. Significantly higher levels of psychological distress were found among high school graduates and those reporting LGBT harassment at home; however, harassment experienced at school was not statistically related to psychological distress. Findings are discussed.

Understanding the neural causes and consequences of posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI) is a high research priority, given the high rates of associated disability and suicide. Despite remarkable progress in elucidating the brain mechanisms of PTSD and mTBI, a comprehensive understanding of these conditions at the level of brain networks has yet to be achieved. The present study sought to identify functional brain networks and topological properties (measures of network organization and function) related to current PTSD severity and mTBI. Graph theoretic tools were used to analyze resting-state functional magnetic resonance imaging data from 208 veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn, all of whom had experienced a traumatic event qualifying for PTSD criterion A. Analyses identified brain networks and topological network properties linked to current PTSD symptom severity, mTBI, and the interaction between PTSD and mTBI. Two brain networks were identified in which weaker connectivity was linked to higher PTSD re-experiencing symptoms, one of which was present only in veterans with comorbid mTBI. Re-experiencing was also linked to worse functional segregation (necessary for specialized processing) and diminished influence of key regions on the network, including the hippocampus. Findings of this study demonstrate that PTSD re-experiencing symptoms are linked to weakened connectivity in a network involved in providing contextual information. A similar relationship was found in a separate network typically engaged in the gating of working memory, but only in veterans with mTBI. Published by Elsevier Inc.

To estimate the prevalence of time pressure experienced by parents in the Nordic countries and examine potential gender disparities as well as associations to parents' family and/or living conditions. 5949 parents of children aged 2-17 years from Denmark, Finland, Norway and Sweden, participating in the 2011 version of the NordChild study, reported their experience of time pressure when keeping up with duties of everyday life. A postal questionnaire addressed to the most active caretaker of the child, was used for data gathering and logistic regression analysis applied. The mother was regarded as the primary caregiver in 83.9% of the cases. Of the mothers, 14.2% reported that they experienced time pressure "most often", 54.7 % reported "sometimes" and 31.1 % reported they did "not" experience time pressure at all. Time pressure was experienced by 22.2 % of mothers in Sweden, 18.4% in Finland, 13.7% in Norway and 3.9% in Denmark, and could be associated to lack of support, high educational level, financial stress, young child age and working overtime. The mother is regarded as the child's primary caregiver among the vast majority of families in spite of living in societies with gender-equal family policies. The results indicate that time pressure is embedded in everyday life of mainly highly-educated mothers and those experiencing financial stress and/or lack of social support. No conclusion could be made about time pressure from the "normbreaking" fathers participating in the study, but associations were found to financial stress and lack of support.

Purpose To examine the associations between adverse interpersonal relationship histories experienced during adolescence and health in young adulthood in a large, nationally representative sample. Methods Using data from Waves I, II and III of the National Longitudinal Study of Adolescent Health, multiple adverse relationship experiences are examined, including high loneliness, low perceived parental support, frequent transitions in romantic relationships (relationship instability), exposure to intimate partner violence, and loss by death of important relationship figures. These histories are assessed, both individually and in a relationship risk index, as predictors of self-reported general health and depressive symptoms at Wave III (ages 18 to 27), controlling for baseline (Wave I) health and for demographic and health behavior covariates. Results Net of baseline health and covariates, each type of relationship risk (experienced between Wave I and Wave III) was related to either depression or general health at Wave III, with the strongest effects seen for exposure to intimate partner violence. In addition, a cumulative relationship risk index examining the extent to which youth experienced high levels of multiple relationship risk factors revealed that each additional adverse relationship experience increased the odds of reporting poor mental and general health at Wave III, with increases occurring in an additive manner. Conclusions Multiple types of adverse relationship experiences predicted increases in poor general health and depressive symptoms from adolescence to early adulthood. Consistent with a cumulative risk hypothesis, the more types of adverse relationship experiences a youth experienced, the worse their young adult health outcomes. PMID:21856520

Developmentally salient research on perceived peer discrimination among minority youths is limited. Little is known about trajectories of perceived peer discrimination across the developmental period ranging from middle childhood to adolescence. Ethically concentrated neighborhoods are hypothesized to protect minority youths from discrimination, but strong empirical tests are lacking. The first aim of the current study was to estimate trajectories of perceived peer discrimination from middle childhood to adolescence, as youths transitioned from elementary to middle and to high school. The second aim was to examine the relationship between neighborhood ethnic concentration and perceived peer discrimination over time. Using a diverse sample of 749 Mexican origin youths (48.9% female), a series of growth models revealed that youths born in Mexico, relative to those born in the U.S., perceived higher discrimination in the 5th grade and decreases across time. Youths who had higher averages on neighborhood ethnic concentration (across the developmental period) experienced decreases in perceived peer discrimination over time; those that had lower average neighborhood ethnic concentration levels showed evidence of increasing trajectories. Further, when individuals experienced increases in their own neighborhood ethnic concentration levels (relative to their own cross-time averages), they reported lower levels of perceived peer discrimination. Neighborhood ethnic concentration findings were not explained by the concurrent changes youths were experiencing in school ethnic concentrations. The results support a culturally-informed developmental view of perceived peer discrimination that recognizes variability in co-ethnic neighborhood contexts. The results advance a view of ethnic enclaves as protective from mainstream threats. PMID:24488094

Does Black Socioeconomic Mobility Explain Recent Progress Toward Black-White Residential Integration?

2017-08-01

Studies of racial residential segregation have found that black-white segregation in U.S. metropolitan areas has declined slowly but steadily since the early 1970s. As of this writing, black-white residential segregation in the United States is approximately 25 % lower than it was in 1970. To identify the sources of this decline, we used individual-level, geocoded data from the Panel Study of Income Dynamics (PSID) to compare the residential attainment of different cohorts of blacks. We analyzed these data using Blinder-Oaxaca regression decomposition techniques that partition the decline in residential segregation among cohorts into the decline resulting from (1) changes in the social and economic characteristics of blacks and (2) changes in the association between blacks' social and economic characteristics and the level of residential segregation they experience. Our findings show that black cohorts entering adulthood prior to the civil rights movement of the 1960s experienced consistently high levels of residential segregation at middle age, but that cohorts transitioning to adulthood during and after this period of racial progress experienced significantly lower levels of residential segregation. We find that the decline in black-white residential segregation for these later cohorts reflects both their greater social and economic attainment and a strengthening of the association between socioeconomic characteristics and residential segregation. Educational gains for the post-civil rights era cohorts and improved access to integrated neighborhoods for high school graduates and college attendees in these later cohorts were the principal source of improved residential integration over this period.

Contextual moderators of momentary cortisol and negative affect in adolescents' daily lives.

To use an ecological momentary assessment design to examine the links between momentary negative affect and cortisol in a sample of adolescents preparing to transition to college. Guided by a risk and resilience framework, we also explored whether important ecological factors, perceived discrimination and social support, moderated the momentary associations between negative affect and youths' cortisol. Adolescents (N = 77) provided salivary samples and diary reports of affect and experiences five times a day over 3 days. They also completed self-report questionnaires on perceived discrimination and social support from family and friends. Within-person increases in momentary negative affect were associated with increases in cortisol. Perceived discrimination and social support from friends moderated this association. Adolescents who reported average and high levels of perceived discrimination experienced exaggerated cortisol responses to negative affect, whereas adolescents who reported low levels of perceived discrimination did not experience significant reactivity to negative affect. In contrast, adolescents who reported high levels of social support from friends experienced attenuated cortisol responses to negative affect compared with adolescents who reported average or low levels of social support from friends. This study contributes to our understanding of youths' daily socioemotional experiences and physiological reactivity by identifying how perceived discrimination and social support from friends amplified and attenuated, respectively, the effects of negative affect on cortisol reactivity. Examining these processes within adolescents' naturalistic environments advances our understanding of the moderating role of ecological characteristics in adolescents' everyday lives.

Struggling toward reward: Recent experience of anhedonia interacts with motivation to predict reward pursuit in the face of a stressful manipulation.

PubMed

Bryant, Jessica; Winer, E Samuel; Salem, Taban; Nadorff, Michael R

2017-01-01

Anhedonia, or the loss of interest and/or pleasure, is a core symptom of depression. Individuals experiencing anhedonia have difficulty motivating themselves to pursue rewarding stimuli, which can result in dysfunction. Action orientation is a motivational factor that might interact with anhedonia to potentially buffer against this dysfunction, as action-oriented individuals upregulate positive affect to quickly motivate themselves to complete goals in the face of stress. The Effort-Expenditure for Rewards Task (EEfRT) is a promising new method for examining differences in motivation in individuals experiencing anhedonia. In the EEfRT, participants choose either easier tasks associated with smaller monetary rewards or harder tasks associated with larger monetary rewards. We examined the relationship between action orientation and EEfRT performance following a negative mood induction in a sample with varying levels of anhedonia. There were two competing hypotheses: (1) action orientation would act as a buffer against anhedonia such that action-oriented individuals, regardless of anhedonic symptoms, would be motivated to pursue greater rewards despite stress, or (2) anhedonia would act as a debilitating factor such that individuals with elevated anhedonic symptoms, regardless of action orientation, would not pursue greater rewards. We examined these hypotheses via Generalized Estimating Equations and found an interaction between anhedonia and action orientation. At low levels of anhedonia, action orientation was associated with effort for reward, but this relationship was not present at high levels of anhedonia. Thus, at low levels of anhedonia, action orientation acted as a buffer against stress, but at high levels, anhedonia debilitated action orientation so that it was no longer a promotive factor.

Sexual harassment of psychiatric trainees: experiences and attitudes.

A survey was carried out of psychiatric trainees' work-related experiences of unwanted sexual contact. A structured postal questionnaire was administered to 100 psychiatric trainees from senior house officer to specialist registrar level in a large psychiatric rotation. There was an 85% response rate; 86% (73) of the sample had experienced unwanted sexual contact, with 47% (40) experiencing deliberate touching, leaning over or cornering, and 18% (15) receiving letters, telephone calls or material of a sexual nature. Three-quarters (64) of respondents had experienced unwanted sexual contact from patients and 64% (54) from staff. Experiences and attitudes did not generally differ by gender, grade or training experience. Four out of 48 female respondents described stalking by patients. Of the 39 respondents who had reported harassment by patients, 31 felt supported by colleagues, while of the 13 who had reported harassment by colleagues, eight felt supported. Two-thirds of the respondents considered sexual harassment 'some-times' or 'frequently' a problem for the profession. Diagnoses of confusional states, mania or schizophrenia made subjects less likely to consider unwanted sexual behaviour to be 'sexual harassment' (86%, 80%, and 67%, respectively), but not for other diagnoses. Levels of threatening and intrusive sexual harassment are unacceptably high in this study group. Health trusts should adopt policies of 'zero tolerance' and all incidents should be reported. Psychological impact on victims should be acknowledged even when the behaviour of the perpetrator can be explained by diagnosis.

Update on the National Cholesterol Education Program Adult Treatment Panel III guidelines: getting to goal.

PubMed

McKenney, James M

2003-09-01

Considerable data on the pathophysiology, epidemiology, and treatment of dyslipidemia-induced coronary heart disease (CHD) have accumulated in recent years. These data have been assessed and incorporated into the guidelines of the National Cholesterol Education Program Expert Panel on the Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel [ATP] III). A major focus of the new guidelines is the assessment of the near-term (i.e., 10-yr) risk of experiencing a CHD event and matching the intensity of treatment to this risk. Patients with diabetes and those with a greater than 20% 10-year risk of experiencing a CHD event have been elevated to the risk level of CHD equivalent. The ATP III guidelines also modify several lipid and lipoprotein classifications. A low-density lipoprotein cholesterol (LDL) level below 100 mg/dl is now considered optimum for all individuals. In addition, high-density lipoprotein cholesterol (HDL) and triglyceride cutoff points have been modified to reflect more accurately the risk associated with abnormalities in these lipoproteins. As with the previous guidelines, the primary target of therapy remains LDL. Therapeutic lifestyle changes consisting of diet, weight reduction, and increased physical activity should be included in all treatment regimens. Based on their potent LDL-lowering properties and their proven ability to decrease mortality in a variety of patient populations, statins are generally the first choice for pharmacologic therapy. A secondary target of therapy includes non-HDL goals for patients with high triglyceride levels and the metabolic syndrome, which is characterized by abdominal obesity, elevated triglyceride levels, low HDL levels, and insulin resistance. Management of these secondary targets includes weight reduction and increased physical activity, and treatment of the lipid and nonlipid risk factors. Overall, ATP III represents an aggressive approach to treating dyslipidemia, greatly extending the number of individuals who qualify for treatment.

A link between occupant and vehicle accelerations during common driving tasks.

When evaluating occupant motions during driving tasks, it is desirable to have a well-established correlation between vehicle and occupant accelerations. Therefore, this study demonstrated a methodology to quantify accelerations experienced by the driver of a passenger vehicle and compare them to associated vehicle motions. Acceleration levels were measured at the seat and the driver’s head, cervical spine, and lumbar spine during six non-collision driving tasks. Tasks included mounting a 127 mm (5 in) -high curb, crossing railroad tracks, driving on a rough road, braking heavily from 13.4 m/s (30 mph), having a 89 mm (3.5 in)-diameter roller sequentially pass under two tires, and dropping one tire from a 171-mm (6.75 in) height. The driver experienced peak resultant accelerations of similar magnitudes across all trials. Peak body accelerations were less than 1.2 g, including 0.82 g lumbar acceleration during heavy braking and 0.88 g head acceleration during the curb mount. These preliminary measurements are comparable to or lower than accelerations experienced during non-driving activities such as sitting quickly. This study contributes to the scientific understanding of accelerations experienced by vehicle occupants and demonstrates the potential to relate vehicle and occupant accelerations during common driving activities that do not involve collisions.

Disturbance History,Spatial Variability, and Patterns of Biodiversity

The intermediate disturbance hypothesis predicts that species diversity will be maximized in environments experiencing intermediate intensity disturbance, after an intermediate timespan. Because many landscapes comprise mosaics with complex disturbance histories, the theory implies that each patch in those mosaics should have a distinct level of diversity reflecting combined impact of the magnitude of disturbance and the time since it occurred. We modeled the changing patterns of species richness across a landscape experiencing varied scenarios of simulated disturbance. Model outputs show that individual landscape patches have highly variable species richness through time, with the details reflecting the timing, intensity and sequence of their disturbance history. When the results are mapped across the landscape, the resulting temporal and spatial complexity illustrates both the contingent nature of diversity and the danger of generalizing about the impacts of disturbance.

Objective Our aim was to develop evidence-informed recommendations for rehabilitation with older adults living with HIV. Design We conducted a knowledge synthesis, combining research evidence specific to HIV, rehabilitation and ageing, with evidence on rehabilitation interventions for common comorbidities experienced by older adults with HIV. Methods We included highly relevant HIV-specific research addressing rehabilitation and ageing (stream A) and high-quality evidence on the effectiveness of rehabilitation interventions for common comorbidities experienced by older adults ageing with HIV (stream B). We extracted and synthesised relevant data from the evidence to draft evidence-informed recommendations for rehabilitation. Draft recommendations were refined based on people living with HIV (PLHIV) and clinician experience, values and preferences, reviewed by an interprofessional team for Grading of Recommendations Assessment, Development, and Evaluation (GRADE) (quality) rating and revision and then circulated to PLHIV and clinicians for external endorsement and final refinement. We then devised overarching recommendations to broadly guide rehabilitation with older adults living with HIV. Results This synthesis yielded 8 overarching and 52 specific recommendations. Thirty-six specific recommendations were derived from 108 moderate-level or high-level research articles (meta-analyses and systematic reviews) that described the effectiveness of rehabilitation interventions for comorbidities that may be experienced by older adults with HIV. Recommendations addressed rehabilitation interventions across eight health conditions: bone and joint disorders, cancer, stroke, cardiovascular disease, mental health challenges, cognitive impairments, chronic obstructive pulmonary disease and diabetes. Sixteen specific recommendations were derived from 42 research articles specific to rehabilitation with older adults with HIV. The quality of evidence from which these recommendations were derived was either low or very low, consisting primarily of narrative reviews or descriptive studies with small sample sizes. Recommendations addressed approaches to rehabilitation assessment and interventions, and contextual factors to consider for rehabilitation with older adults living with HIV. Conclusions These evidence-informed recommendations provide a guide for rehabilitation with older adults living with HIV. PMID:24833687

Background Emerging adults have the highest prevalence of heavy drinking as compared to all other age groups. Given the negative consequences associated with such drinking, additional research efforts focused on at-risk consumption are warranted. The current study sought to identify patterns of situational antecedents to drinking and to examine their associations with drinking motivations, alcohol involvement, and mental health functioning in a sample of heavy drinking college students. Method Participants were 549 (65.8% women) college student drinkers. Results Latent profile analysis identified three classes based on likelihood of heavy drinking across eight situational precipitants. The “High Situational Endorsement” group reported the greatest likelihood of heavy drinking in most situations assessed. This class experienced the greatest level of alcohol-related harms as compared to the “Low Situational Endorsement” and “Moderate Situational Endorsement” groups. The Low Situational Endorsement class was characterized by the lowest likelihood of heavy drinking across all situational antecedents and they experienced the fewest alcohol-related harms, relative to the other classes. Class membership was related to drinking motivations with the “High Situational Endorsement” class endorsing the highest coping- and conformity-motivated drinking. The “High Situational Endorsement” class also reported experiencing more mental health symptoms than other groups. Conclusions The current study contributed to the larger drinking literature by identifying profiles that may signify a particularly risky drinking style. Findings may help guide intervention work with college heavy drinkers. PMID:28163666

The purpose of the current study was to evaluate the postural stability of single-leg standing on the retiré position in ballet dancers having three different levels of skill. Nine superior experienced female ballet dancers, 9 experienced, and 12 novice dancers performed single-leg standing in the retiré position. The parameters of center of pressure (COP) in the anterior-posterior and medial-lateral directions and the maximum distance between COP and the center of mass (COM) were measured. The inclination angles of body segments (head, torso, and supporting leg) in the frontal plane were also calculated. The findings showed that the novice dancers had a trend of greater torso inclination angles than the experienced dancers but that the superior experienced dancers had greater maximum COM-COP distance in the anterior-posterior direction. Furthermore, both experienced and novice dancers had better balance when standing on the nondominant leg, whereas the superior experienced dancers had similar postural stability between legs. Based on the findings, ballet training should put equal focus on both legs and frontal plane control (medial-lateral direction) should be integrated to ballet training program.

Theory predicts that males should increase overall investment in ejaculate expenditure with increasing levels of sperm competition. Since ejaculate production is costly, we may expect males to tailor their reproductive investment according to anticipated levels of sperm competition. Here, we investigate plasticity in ejaculate investment in response to cues of population average levels of sperm competition in a promiscuous mammal, the bank vole (Myodes glareolus). We manipulated the social experience of experimental subjects during sexual development via differential exposure to the odour of rival males, to simulate conditions associated with relatively high or low average levels of sperm competition. Males exposed to a high level of competition developed larger major accessory reproductive glands (seminal vesicles) than those that experienced a low level of competition, suggesting that an increased investment in the production of copulatory plugs and/or mating rate may be beneficial at relatively high sperm competition levels. However, investment in sperm production, testis size and sperm motility were not altered according to social experience. Our findings emphasize the importance of non-sperm components of the ejaculate in mammalian postcopulatory sexual selection, and add to the growing evidence linking plasticity in reproductive traits to social cues of sperm competition.

Many populations of threatened mammals persist outside formally protected areas, and their survival depends on the willingness of communities to coexist with them. An understanding of the attitudes, and specifically the tolerance, of individuals and communities and the factors that determine these is therefore fundamental to designing strategies to alleviate human-wildlife conflict. We conducted a meta-analysis to identify factors that affected attitudes toward 4 groups of terrestrial mammals. Elephants (65%) elicited the most positive attitudes, followed by primates (55%), ungulates (53%), and carnivores (44%). Urban residents presented the most positive attitudes (80%), followed by commercial farmers (51%) and communal farmers (26%). A tolerance to damage index showed that human tolerance of ungulates and primates was proportional to the probability of experiencing damage while elephants elicited tolerance levels higher than anticipated and carnivores elicited tolerance levels lower than anticipated. Contrary to conventional wisdom, experiencing damage was not always the dominant factor determining attitudes. Communal farmers had a lower probability of being positive toward carnivores irrespective of probability of experiencing damage, while commercial farmers and urban residents were more likely to be positive toward carnivores irrespective of damage. Urban residents were more likely to be positive toward ungulates, elephants, and primates when probability of damage was low, but not when it was high. Commercial and communal farmers had a higher probability of being positive toward ungulates, primates, and elephants irrespective of probability of experiencing damage. Taxonomic bias may therefore be important. Identifying the distinct factors explaining these attitudes and the specific contexts in which they operate, inclusive of the species causing damage, will be essential for prioritizing conservation investments. © 2014 The Authors.

Increasing levels of obesity could compromise future gains in life expectancy in low- and high-income countries. Although excess mortality associated with obesity and, more generally, higher levels of body mass index (BAI) have been investigated in the United States, there is little research about the impact of obesity on mortality in Latin American countries, where very the rapid rate of growth of prevalence of obesity and overweight occur jointly with poor socioeconomic conditions. The aim of this article is to assess the magnitude of excess mortality due to obesity and overweight in Mexico and the United States. For this purpose, we take advantage of two comparable data sets: the Health and Retirement Study 2000 and 2004 for the United States, and the Mexican Health and Aging Study 2001 and 2003 for Mexico. We find higher excess mortality risks among obese and overweight individuals aged 60 and older in Mexico than in the United States. Yet, when analyzing excess mortality among different socioeconomic strata, we observe greater gaps by education in the United States than in Mexico. We also find that although the probability of experiencing obesity-related chronic diseases among individuals with high BMI is larger for the U.S. elderly, the relative risk of dying conditional on experiencing these diseases is higher in Mexico.

There is little evidence about how to improve outcomes for high-risk young people, of whom Indigenous young people are disproportionately represented, due to few evaluation studies of interventions. One way to increase the evidence is to have researchers and service providers collaborate to embed evaluation into the routine delivery of services, so program delivery and evaluation occur simultaneously. This study aims to demonstrate the feasibility of integrating best-evidence measures into the routine data collection processes of a service for high-risk young people, and identify the number and nature of risk factors experienced by participants. The youth service is a rural based NGO comprised of multiple program components: (i) engagement activities; (ii) case management; (iii) diversionary activities; (iv) personal development; and (v) learning and skills. A best-evidence assessment tool was developed by staff and researchers and embedded into the service's existing intake procedure. Assessment items were organised into demographic characteristics and four domains of risk: education and employment; health and wellbeing; substance use; and crime. Descriptive data are presented and summary risk variables were created for each domain of risk. A count of these summary variables represented the number of co-occurring risks experienced by each participant. The feasibility of this process was determined by the proportion of participants who completed the intake assessment and provided research consent. This study shows 85% of participants completed the assessment tool demonstrating that data on participant risk factors can feasibly be collected by embedding a best-evidence assessment tool into the routine data collection processes of a service. The most prevalent risk factors were school absence, unemployment, suicide ideation, mental distress, substance use, low levels of physical activity, low health service utilisation, and involvement in crime or with the juvenile justice system. All but one participant experienced at least two co-occurring domains of risk, and the majority of participants (58%) experienced co-occurring risk across four domains. This is the first study to demonstrate that best-evidence measures can feasibly be embedded into the routine data collection processes of a service for high-risk young people. This process allows services to tailor their activities to the most prevalent risks experienced by participants, and monitor these risks over time. Replication of this process in other services would improve the quality of services, facilitate more high quality evaluations of services, and contribute evidence on how to improve outcomes for high-risk young people.

Chronic stress and sexual function in women

Introduction Chronic stress is known to have negative effects on reproduction, but little is known about how it affects the sexual response cycle. The present study examined the relationship between chronic stress and sexual arousal and the mechanisms that mediate this relationship. Aim To test the relationship between chronic stress and sexual arousal and identify mechanisms that may explain this relationship. We predicted that women experiencing high levels of chronic stress would show lower levels of genital arousal & DHEAS and higher levels of cortisol and cognitive distraction compared to women with average levels of stress. Methods Women who were categorized as high in chronic stress (high stress group, n = 15) or average in chronic stress (average stress group; n = 15) provided saliva samples and watched an erotic film while having their genital and psychological arousal measured. Main Outcome Measures Main outcome measures were vaginal pulse amplitude, psychological arousal, salivary cortisol, salivary DHEAS, and heart rate and compared them between women with high and average levels of chronic stress. Results Women in the high stress group had lower levels of genital, but not psychological arousal, had higher levels of cortisol, and reported more distraction during the erotic film than women in the average stress group. The main predictor of decreased genital sexual arousal was participants’ distraction scores. Conclusions High levels of chronic stress were related to lower levels of genital sexual arousal. Both psychological (distraction) and hormonal (increased cortisol) factors were related to the lower levels of sexual arousal seen in women high in chronic stress, but distraction was the only significant predictor when controlling for other variables.

To determine the prevalence of professional burnout among microvascular free-flap (MVFF) head and neck surgeons and to identify modifiable risk factors with the intent to reduce MVFF surgeon burnout. A cross-sectional, observational study. A questionnaire mailed to MVFF surgeons in the United States. A total of 60 MVFF surgeons. Professional burnout was quantified using the Maslach Burnout Inventory- Human Services Study questionnaire, which defines burnout as the triad of high emotional exhaustion (EE), high depersonalization (DP), and low personal accomplishment. Additional data included demographic information and subjective assessment of professional stressors, satisfaction, self-efficacy, and support systems using Likert score scales. Potential risk factors for burnout were determined via significant association (P < .05) by Fisher exact tests and analyses of variance. Of the 141 mailed surveys, 72 were returned, for a response rate of 51%, and 60 of the respondents were practicing MVFF surgeons. Two percent of the responding MVFF surgeons experienced high burnout (n = 1); 73%, moderate burnout (n = 44); and 25%, low burnout (n = 15). Compared with other otolaryngology academic faculty and department chairs, MVFF surgeons had similar or lower levels of burnout. On average, MVFF surgeons had low to moderate EE and DP scores. High EE was associated with excess workload, inadequate administration time, work invading family life, inability to care for personal health, poor perception of control over professional life, and frequency of irritable behavior toward loved ones (P < .001). On average, MVFF surgeons experienced high personal accomplishment. Most MVFF surgeons experience moderate professional burnout secondary to moderate EE and DP. This may be a problem of proper balance between professional obligations and personal life goals. Most MVFF surgeons, nonetheless, experience a high level of personal accomplishment in their profession.

Few longitudinal studies have investigated how cyberbullying interacts with traditional bullying among young people, who are increasingly using online environments to seek information, entertainment and to socialise. This study aimed to identify the associations between the relative contribution of cyberbullying victimisation and traditional bullying victimisation on social and emotional antecedents and outcomes among adolescents. Participants were a cohort of 1,504 adolescents from 16 Australian schools followed from age 13 to 15 years. Adolescents experiencing social and emotional difficulties were more likely to be cyberbullied and traditionally bullied, than traditionally bullied only. Those targeted in both ways experienced more harm and stayed away from school more often than those traditionally bullied only. These findings suggest a high coexistence of cyber and traditional bullying behaviours and their antecedents, and higher levels of harm from a combination of these behaviours for adolescents over time. Future research should engage students as co-researchers to enhance school and parent strategies to support adolescents experiencing difficulties, and to reduce the likelihood of both cyber and traditional bullying.

Intimate partner violence (IPV) is a prevalent and pressing public health concern that affects people of all gender and sexual identities. Though studies have identified that male couples may experience IPV at rates as high as or higher than women in heterosexual partnerships, the body of literature addressing this population is still nascent. This study recruited 160 male-male couples in Atlanta, Boston, and Chicago to independently complete individual surveys measuring demographic information, partner violence experience and perpetration, and individual and relationship characteristics that may shape the experience of violence. Forty-six percent of respondents reported experiencing IPV in the past year. Internalized homophobia significantly increased the risk for reporting experiencing, perpetrating, or both for any type of IPV. This study is the first to independently gather data on IPV from both members of male dyads and indicates an association between internalized homophobia and risk for IPV among male couples. The results highlight the unique experiences of IPV in male-male couples and call for further research and programmatic attention to address the exorbitant levels of IPV experienced within some of these partnerships.

We aimed to assess comprehensively the prevalence of perinatal risks experienced by a potentially high-risk yet understudied population of children domestically adopted in the United States. Data are from participant report and medical records from mothers (n = 580) who completed a domestic adoption placement with nonrelatives at or near birth (Mean placement age = 7 days). We describe a comprehensive measure of perinatal risks, including divergences from previous assessment tools and the incorporation of multiple reporters, and report the prevalence of various types of perinatal risks. The prevalence of each specific risk factor was generally low, although several risks were more prevalent in this sample than estimates from nationally representative publicly available data. Nearly the entire sample (99%) experienced some type of risk exposure. Birth mothers who placed their children for adoption domestically in the US experience higher levels of perinatal risks than the national average, but not for all specific types of risk. Thus, the developmental trajectories of children adopted domestically may systematically differ from the general population to the extent that these specific perinatal risks impact development.

Accuracy, reliability, and timing of visual evaluations of decay in fresh-cut lettuce

PubMed Central

Hayes, Ryan J.

2018-01-01

Visual assessments are used for evaluating the quality of food products, such as fresh-cut lettuce packaged in bags with modified atmosphere. We have compared the accuracy and the reliability of visual evaluations of decay on fresh-cut lettuce performed with experienced and inexperienced raters. In addition, we have analyzed decay data from over 4.5 thousand bags to determine the optimum timing for evaluations to detect differences among accessions. Lin’s concordance coefficient (ρc) that takes into consideration both the closeness of the data and the conformance to the identity line showed high repeatability (intra-rater reliability, ρc = 0.97), reproducibility (inter-rater reliability, ρc = 0.92), and accuracy (ρc = 0.96) for experienced raters. Inexperienced raters did not perform as well and their ratings showed decreased repeatability (ρc = 0.93), but even larger reduction in reproducibility (ρc = 0.80) and accuracy (ρc = 0.90). We have detected that 5.3% of ratings were outside of the 95% limits of agreement. These under- or overestimates were predominantly found for bags with intermediate levels of decay, which corresponds to the middle of the rating scale. This occurs because intermediate amounts of decay are more difficult to discriminate than extremes. The frequencies of aberrant ratings for experienced raters ranged from 0.6% to 4.4% (mean = 2.1%), for inexperienced raters the frequencies were substantially higher, ranging from 6.1% to 15.6% (mean = 9.4%). Therefore, we recommend that new raters receive training that includes practical examples in this range of decay, use of standard area diagrams, and continuing interaction with experienced raters (consultation during actual rating). Very high agreement among experienced raters indicate that visual ratings can be successfully used for evaluations of decay, until a more objective, rapid, and affordable method is developed. We recommend evaluating samples at multiple time points until 42 days after processing (about 80% decay on average) and then combining these individual ratings into the area under the decay progress stairs (AUDePS) score. Applying this approach, experienced evaluators can accurately detect difference among lettuce accessions and identify lettuce cultivars with reduced decay. PMID:29664945

Childhood family disruptions and adult well-being: the differential effects of divorce and parental death.

PubMed

Mack, K Y

2001-01-01

This study draws on attachment theory and social learning theory and uses data from the National Survey of Families and Households to examine the differential effects of childhood family disruptions on adult well-being. Comparisons are made between adults who experienced parental divorce, adults who experienced parental death, and adults who were raised in intact families (N = 4,341). The present study differs from previous research by making direct comparisons between different family disruption groups, assessing the effects of family disruptions that occur before age 19, and including multiple measures of adult well-being as dependent variables. Consistent with hypotheses and inferences made from comparisons with adults from intact families, adults who experienced parental divorce report lower levels of parent-child relationship quality, higher levels of self-confidence, and lower levels of depression than adults who experienced parental death during childhood. Therefore, studies that fail to take type of childhood family disruption into account will lead to inaccurate and misleading conclusions about the effects of these experiences on adult outcomes.

To assess the diagnostic accuracy of computed tomography coronary angiography (CTCA) using a combination of high-definition CT (HD-CTCA) and high level of reader experience, with invasive coronary angiography (ICA) as the reference standard, in high-risk patients for the investigation of coronary artery disease (CAD). Three hundred high-risk patients underwent HD-CTCA and ICA. Independent experts evaluated the images for the presence of significant CAD, defined primarily as the presence of moderate (≥ 50%) stenosis and secondarily as the presence of severe (≥ 70%) stenosis in at least one coronary segment, in a blinded fashion. HD-CTCA was compared to ICA as the reference standard. No patients were excluded. Two hundred and six patients (69%) had moderate and 178 (59%) had severe stenosis in at least one vessel at ICA. The sensitivity, specificity, positive predictive value, and negative predictive value were 97.1%, 97.9%, 99% and 93.9% for moderate stenosis, and 98.9%, 93.4%, 95.7% and 98.3%, for severe stenosis, on a per-patient basis. The combination of HD-CTCA and experienced readers applied to a high-risk population, results in high diagnostic accuracy comparable to ICA. Modern generation CT systems in experienced hands might be considered for an expanded role. Copyright © 2015 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

Achieving high rates of adherence to antiretroviral therapy (ART) in resource-poor settings comprises serious, but different, challenges in both the first months of treatment and during the life-long maintenance phase. We measured the impact of a health system-oriented, facility-based intervention to improve clinic attendance and patient adherence. This was a quasi-experimental, longitudinal, controlled intervention study using interrupted time series analysis. The intervention consisted of (1) using a clinic appointment diary to track patient attendance and monitor monthly performance; (2) changing the mode of asking for self-reported adherence; (3) training staff on adherence concepts, intervention methods, and use of monitoring data; (4) conducting visits to support facility teams with the implementation.We conducted the study in 12 rural district hospitals (6 intervention, 6 control) in Kenya and randomly selected 1894 adult patients over 18 years of age in two cohorts: experienced patients on treatment for at least one year, and newly treated patients initiating ART during the study. Outcome measures were: attending the clinic on or before the date of a scheduled appointment, attending within 3 days of a scheduled appointment, reporting perfect adherence, and experiencing a gap in medication supply of more than 14 days. Among experienced patients, the percentage attending the clinic on or before a scheduled appointment increased in both level (average total increase immediately after intervention) (+5.7%; 95% CI=2.1, 9.3) and trend (increase per month) (+1.0% per month; 95% CI=0.6, 1.5) following the intervention, as did the level and trend of those keeping appointments within three days (+4.2%; 95% CI=1.6, 6.7; and +0.8% per month; 95% CI=0.6, 1.1, respectively). The relative difference between the intervention and control groups based on the monthly difference in visit rates increased significantly in both level (+6.5; 95% CI=1.4, 11.6) and trend (1.0% per month; 95% CI=0.2, 1.8) following the intervention for experienced patients attending the clinic within 3 days of their scheduled appointments.The decrease in the percentage of experienced patients with a medication gap greater than 14 days approached statistical significance (-11.3%; 95% CI=-22.7, 0.1), and the change seemed to persist over 11 months after the intervention. All facility staff used appointment-keeping data to calculate adherence and discussed outcomes regularly. The appointment-tracking system and monthly performance monitoring was strengthened, and patient attendance was improved. Scale-up to national level may be considered.

Effects of pedagogical ideology on the perceived loudness and noise levels in preschools

High activity noise levels that result in detrimental effects on speech communication have been measured in preschools. To find out if different pedagogical ideologies affect the perceived loudness and levels of noise, a questionnaire study inquiring about the experience of loudness and voice symptoms was carried out in Iceland in eight private preschools, called “Hjalli model”, and in six public preschools. Noise levels were also measured in the preschools. Background variables (stress level, age, length of working career, education, smoking, and number of children per teacher) were also analyzed in order to determine how much they contributed toward voice symptoms and the experience of noisiness. Results indicate that pedagogical ideology is a significant factor for predicting noise and its consequences. Teachers in the preschool with tighter pedagogical control of discipline (the “Hjalli model”) experienced lower activity noise loudness than teachers in the preschool with a more relaxed control of behavior (public preschool). Lower noise levels were also measured in the “Hjalli model” preschool and fewer “Hjalli model” teachers reported voice symptoms. Public preschool teachers experienced more stress than “Hjalli model” teachers and the stress level was, indeed, the background variable that best explained the voice symptoms and the teacher's perception of a noisy environment. Discipline, structure, and organization in the type of activity predicted the activity noise level better than the number of children in the group. Results indicate that pedagogical ideology is a significant factor for predicting self-reported noise and its consequences. PMID:26356370

Effects of highly active antiretroviral therapy on thymical reconstitution of CD4 T lymphocytes in vertically HIV-infected children.

2002-05-24

CD4 T-cell percentages, viral load and thymic function measured as T-cell receptor rearrangement excision circle (TREC) levels were determined every 2-3 months in six treated HIV-infected children for 4 years. All children experienced a marked increase in CD4 cell count after therapy, accompanied by a concomitantly marked increase in TREC levels. In children, the decrease in viral load caused by antiviral therapy leads to an increase in CD4 T cells, mainly because of a recovery in the thymic production of new T cells.

As first responders to an increasing number of natural and manmade disasters, active-duty firefighters are at increased risk for physical and psychiatric impairment as reflected by high rates of posttraumatic stress disorder (PTSD). Because little is known about related factor with PTSD according to job stress level among firefighters, we assessed utility of the Minnesota Multiphasic Personality Inventory (MMPI) using 5-year medical surveillance. Data were analyzed from 185 male firefighters without psychiatric disease history and who at assessments in 2006 and 2011 completed all questionnaires on personal behaviors (including exercise, drinking and smoking habits) and job history (including job duration and department). MMPI, Events Scale-Revised-Korean version (IES-R-K) and Korean Occupational Stress Scale-Short Form (KOSS-SF) were used to screen for personality trait, PTSD symptom presence and job stress level, respectively. IES-R-K subgroups were compared using two-sample t- and χ2 tests, and factors influencing IES-R-K according to KOSS-SF were determined using uni- and multivariate logistic regression. Mean age and job duration were higher in PTSD-positive than negative groups. In multivariate analysis, increased PTSD risk was associated with: job duration (Odds ratio (OR) = 1.064, 95 % CI 1.012-1.118) for firefighters overall; masculinity-femininity (OR = 5.304, 95 % CI 1.191-23.624) and job duration (OR = 1.126, 95 % CI 1.003-1.265) for lower job stress level; and social introversion (OR = 3.727, 95 % CI 1.096-12.673) for higher job stress level. MMPI relates with PTSD according to job stress level among experienced firefighters. Masculinity-femininity and social introversion were the strongest related factor for PTSD symptom development in low and high job stress levels, respectively.

Purpose: To determine the maximally tolerated dose of sorafenib delivered before, during, and after stereotactic body radiation therapy (SBRT) in hepatocellular carinoma (HCC). Methods and Materials: Eligible patients had locally advanced Child-Pugh class A HCC, showed Eastern Cooperative Oncology Group performance status 0-1, and were ineligible for standard local-regional therapies. Sorafenib was dose escalated in 2 strata: (1) low effective irradiated liver volume (veff) < 30% and (2) high veff 30%to 60%. Sorafenib (400 mg daily = dose level 1) was administered for 12 weeks, with 6 fractions SBRT delivered weeks 2 and 3, and escalation to full dose (400 mg twice daily) after 12 weeks as tolerated.more » Standard 3 + 3 cohorts with dose escalation of sorafenib were planned. Results: Sixteen patients (4 low veff, median dose 51 Gy; 12 high veff, median dose 33 Gy) were treated at 2 sorafenib dose levels. Of those patients 75% were had Barcelona Clinic Liver Cancer stage C, and 63% had main branch portal vein invasion. In the low veff stratum, no dose-limiting toxicities (DLTs) were observed in 4 patients treated with SBRT and sorafenib 400 mg. Inb the high veff stratum: 2 of 3 evaluable patients treated with sorafenib 400 mg experienced DLT (grade 3 large bowel bleed and grade 4 bowel obstruction 51 and 27 days, respectively, after SBRT). One of 6 evaluable patients at dose level −1 (200 mg once daily) experienced a grade 3 tumor rupture at week 5. Median overall survival and in-field local progression have not been reached. Worsening of Child-Pugh liver function class was seen in 6 of 12 patients in the high veff stratum. Conclusions: Significant toxicity was observed in the high veff stratum, and concurrent SBRT with sorafenib is not recommended outside a clinical trial.« less

Saliva pH as a biomarker of exam stress and a predictor of exam performance.

Salivary pH is regulated by the sympathetic and parasympathetic nervous system; therefore, it may serve as a biomarker of stress. To assess the associations between the cognitive and emotional dimensions of exam stress and pH levels, and the predictability of salivary pH in relation to test performance. A prospective study. Eighty-three nursing students answered a questionnaire on stress appraisals, experienced stress, test anxiety (including worry and emotionality subscales) and health behaviors, and gave a saliva sample for measuring pH on the morning of their first term exam and three months later. Their performance on the test (grades) was also recorded. Levels of pH in saliva were higher (levels of acidity were lower) in the post exam compared to the exam period, in parallel to lower threat appraisal, experienced stress, and test anxiety levels post exam. Controlling for smoking, physical activity and working hours per week, pH levels at both time points were predicted by appraised threat regarding the exam situation, experienced stress, and the emotionality dimension of test anxiety. pH at Time 1 predicted performance on the exams and mediated the associations of experienced stress and emotionality subscale with test performance. the present study indicates that pH levels may serve as a reliable, accessible and inexpensive means by which to assess the degree of physiological reactions to exams and other naturalistic stressors.

Troponin levels have been correlated with adverse outcomes in multiple disease processes, including congestive heart failure, acute coronary syndromes, sepsis, and, in a few small series, infective endocarditis. We hypothesized that a novel measurement of troponin using a highly sensitive assay would correlate with adverse outcomes when prospectively studied in patients with infective endocarditis. At a single center in the International Collaboration on Endocarditis, 42 patients met the inclusion criteria and underwent testing for cardiac troponin T (cTnT) using both a standard and a highly sensitive precommercial assay. The cTnT levels were associated with the prespecified primary composite outcome of death, central nervous system event, and cardiac abscess. Secondary outcomes included the individual components of the composite outcome and the need for cardiac surgery. A receiver operating characteristic curve was derived and used to identify the optimal cutpoint for cTnT using the highly sensitive assay. cTnT was detectable with the highly sensitive assay in 39 (93%) of 42 patients with infective endocarditis and with the standard assay in 25 (56%) of 42 (p <0.05). Of the 42 patients, 15 experienced the composite outcome, 4 died, 9 had a central nervous system event, and 5 had a cardiac abscess. With the hs-cTnT assay, the median cTnT was greater in the patients who experienced the primary outcome (0.12 vs 0.02 ng/ml, p <0.05). According to the receiver operating characteristic curve analysis (area under the curve of 0.74), cTnT levels of ≥0.08 ng/ml produced optimal specificity (78%) for the primary outcome. The patients with a cTnT level of ≥0.08 ng/ml were more likely to experience the primary outcome (odds ratio 7.0, 95% confidence interval 1.7 to 28.6, p <0.01) and a central nervous system event (odds ratio 9.3, 95% confidence interval 1.3 to 24.1, p = 0.02). In conclusion, cTnT is detectable in 93% of patients with infective endocarditis using a novel highly sensitive assay, with higher levels correlating with poor clinical outcomes.

To explore the state of resilience and its predictors among nurses in mainland China. Resilience is considered as an important ability to influence the prevention of job dissatisfaction and burnout. There are few studies on resilience in Chinese nurses, particularly investigating the predictors of resilience. A cross-sectional survey was employed and 1061 nurses from six three-level hospitals in Hunan responded to participate in the study. Data were collected using self-reported questionnaires. Nurses experienced moderate levels of resilience and self-efficacy and tended to use a positive coping style. Multiple linear regression showed that a high level of self-efficacy and education, having a positive coping style rather than a negative coping style, exercising regularly and not using cigarettes predicted a high level of resilience (P < 0.01). This study shows a moderate level of resilience among nurses and suggests that a high level of self-efficacy and education, as well as having a positive coping style and choosing a healthy lifestyle may increase nurses' resilience. Hospital administrators and nursing managers need to explore the resilience state among nurses and understand the predictors of resilience. Then, scientific and evidence-based interventions for improving resilience should be adopted. © 2017 John Wiley & Sons Ltd.

Approximately 5,000,000 athletes play organized football in the United States, and youth athletes constitute the largest proportion with ∼3,500,000 participants. Investigations of head impact exposure (HIE) in youth football have been limited in size and duration. The objective of this study was to evaluate HIE of athletes participating in three age- and weight-based levels of play within a single youth football organization over four seasons. Head impact data were collected using the Head Impact Telemetry (HIT) System. Mixed effects linear models were fitted, and Wald tests were used to assess differences in head accelerations and number of impacts among levels and session type (competitions vs. practices). The three levels studied were levels A (n = 39, age = 10.8 ± 0.7 years, weight = 97.5 ± 11.8 lb), B (n = 48, age = 11.9 ± 0.5 years, weight = 106.1 ± 13.8 lb), and C (n = 32, age = 13.0 ± 0.5 years, weight = 126.5 ± 18.6 lb). A total of 40,538 head impacts were measured. The median/95th percentile linear head acceleration for levels A, B, and C was 19.8/49.4g, 20.6/51.0g, and 22.0/57.9g, respectively. Level C had significantly greater mean linear acceleration than both levels A (p = 0.005) and B (p = 0.02). There were a significantly greater number of impacts per player in a competition than in a practice session for all levels (A, p = 0.0005, B, p = 0.0019, and C, p < 0.0001). Athletes at lower levels experienced a greater percentage of their high magnitude impacts (≥ 80g) in practice, whereas those at the highest level experienced a greater percentage of their high magnitude impacts in competition. These data improve our understanding of HIE within youth football and are an important step in making evidence-based decisions to reduce HIE.

Thyroid storm is a rare disorder with a sudden onset, rapid progression and high mortality. We experienced a case of thyroid storm which had a devastating course, including multiple organ failure (MOF), severe hypoglycemia, disseminated intravascular coagulation (DIC), and stroke. It was difficult to make a diagnosis of thyroid storm in the present patient, because she did not have a history of thyroid disease and her serum FT3 level was normal. Clinicians should be aware that thyroid storm can occur even when there is an almost normal level of thyroid hormones, and that intensive anticoagulation is required for patients with atrial fibrillation to prevent stroke after thyroid storm.

Solar Radiation during Rewarming from Torpor in Elephant Shrews: Supplementation or Substitution of Endogenous Heat Production?

Many small mammals bask in the sun during rewarming from heterothermy, but the implications of this behaviour for their energy balance remain little understood. Specifically, it remains unclear whether solar radiation supplements endogenous metabolic thermogenesis (i.e., rewarming occurs through the additive effects of internally-produced and external heat), or whether solar radiation reduces the energy required to rewarm by substituting (i.e, replacing) metabolic heat production. To address this question, we examined patterns of torpor and rewarming rates in eastern rock elephant shrews (Elephantulus myurus) housed in outdoor cages with access to either natural levels of solar radiation or levels that were experimentally reduced by means of shade cloth. We also tested whether acclimation to solar radiation availability was manifested via phenotypic flexibility in basal metabolic rate (BMR), non-shivering thermogenesis (NST) capacity and/or summit metabolism (Msum). Rewarming rates varied significantly among treatments, with elephant shrews experiencing natural solar radiation levels rewarming faster than conspecifics experiencing solar radiation levels equivalent to approximately 20% or 40% of natural levels. BMR differed significantly between individuals experiencing natural levels of solar radiation and conspecifics experiencing approximately 20% of natural levels, but no between-treatment difference was evident for NST capacity or Msum. The positive relationship between solar radiation availability and rewarming rate, together with the absence of acclimation in maximum non-shivering and total heat production capacities, suggests that under the conditions of this study solar radiation supplemented rather than substituted metabolic thermogenesis as a source of heat during rewarming from heterothermy.

2014-10-01

The family stress model proposes that financial stress experienced by parents is associated with problem behavior in adolescents. The present study applied an actor-partner interdependence approach to the family stress model and focused on low-, middle-, and high-income families to broaden our understanding of the pathways by which the financial stress of mothers and fathers are related to adolescent outcomes. The study uses dyadic data (N = 798 heterosexual couples) from the Relationship between Mothers, Fathers and Children study in which two-parent families with an adolescent between 11 and 17 years of age participated. Path-analytic results indicated that in each of the families the association between parents' financial stress and problem behavior in adolescents is mediated through parents' depressive symptoms, interparental conflict, and positive parenting. Family stress processes also appear to operate in different ways for low-, middle-, and high-income families. In addition to a higher absolute level of financial stress in low-income families, financial stress experienced by mothers and fathers in these families had significant direct and indirect effects on problem behavior in adolescents, while in middle- and high-income families only significant indirect effects were found. The financial stress of a low-income mother also had a more detrimental impact on her level of depressive feelings than it had on mothers in middle-income families. Furthermore, the study revealed gender differences in the pathways of mothers and fathers. Implications for research, clinical practice, and policy are also discussed.

Poor psychological outcomes are common among trauma survivors, yet not all survivors experience adverse sequelae. The current study examined links between cumulative trauma exposure as a function of the level of betrayal (measured by the relational closeness of the survivor and the perpetrator), trauma appraisals, gender, and trauma symptoms. Participants were 273 college students who reported experiencing at least one traumatic event on a trauma checklist. Three cumulative indices were constructed to assess the number of different types of traumas experienced that were low (LBTs), moderate (MBTs), or high in betrayal (HBTs). Greater trauma exposure was related to more symptoms of depression, dissociation, and PTSD, with exposure to HBTs contributing the most. Women were more likely to experience HBTs than men, but there were no gender differences in trauma-related symptoms. Appraisals of trauma were predictive of trauma-related symptoms over and above the effects explained by cumulative trauma at each level of betrayal. The survivor's relationship with the perpetrator, the effect of cumulative trauma, and their combined impact on trauma symptomatology are discussed.

We studied occupational stress and its psychosocial effects in a sample of Italian radiologists and radiotherapists: Radiologists and radiotherapists attending two medical conferences were invited to complete a questionnaire comprising four sections investigating the risk of occupational stress (organisational discomfort, Karasek's Job Content Questionnaire, Siegrist's Effort-Reward Imbalance, Warr's Job Satisfaction) and four sections investigating the health effects of such stress (Goldberg's Anxiety and Depression Scales, General Health Questionnaire, Lifestyles Questionnaire). Radiologists and radiotherapists generally expressed high levels of control, reward and satisfaction. However, 38.5% complained of severe organisational discomfort, 24% reported job strain, 28% reported effort/reward imbalance and 25% were dissatisfied. Female radiologists and radiotherapists showed higher levels of organisational discomfort than their male colleagues. Younger and less experienced radiologists and radiotherapists had higher strain scores than their older and more experienced colleagues. A significant correlation was observed between stress predictors and the effects of stress on health, including depression and anxiety, psychological distress and unhealthy lifestyles. Radiologists and radiotherapists are exposed to major occupational stress factors, and a significant percentage of them suffer from workplace stress. A special effort is required to prevent this condition.

To investigate the levels and causes of work-related frustration among senior nurses. Role changes and the associated expectations and setbacks faced by senior middle-aged nurses can easily result in low morale. Therefore, working setbacks experienced by senior nurses must be investigated. A cross-sectional questionnaire study. Purposive sampling was used to select questionnaire recipients. In total, 482 senior nurses completed and returned a structured questionnaire. The predictive factors for frustration at work among senior nurses included age, service unit, and the impact of sleep disorders, which jointly explained 54% of the variance. In particular, age and service unit were important predictive factors for frustration at work. Senior nurses had medium-to-low scores for frustration at work and did not perceive a high level of frustration. The outpatient departments and other medical departments in this sector should provide a reasonable system of incentives and promotion opportunities if they are to retain their most senior and experienced nurses. The results of this study could serve as a reference for hospital administrations. © 2016 John Wiley & Sons Ltd.

Post Traumatic Stress Disorder (PTSD) is still a diagnosis which is frequently missed even by psychiatric professionals. Each doctor needs to maintain a high level of awareness that patients may have experienced trauma; that PTSD can often occur for a variety of common symptoms; and that it may also be at the root of a persisting treatment-resistant depressive or anxiety state. This case demonstrates that occupational accidents may result in this condition.

This study examined the profiles of symptoms and health-related quality of life (QOL) of women in substance abuse treatment, comparing those with higher versus lower histories of adverse childhood events (ACE), and those with versus without current pain. Adult women in outpatient substance abuse treatment (n = 30) completed questionnaires (cross-sectional study) on topics including drug use, adverse childhood events (ACE), QOL, functional ability, current pain, and depression. Women with pain indicated significant differences in emotional (p < 0.05), and functional ability (p < 0.01); but no significant differences were found between women with high versus low levels of ACE. Yet, radar plots of women with both current pain and high levels of ACE, versus those without, portrayed a distinctive profile indicating high levels of anxiety and depression. Rather than a checklist, visual composites of symptoms experienced by women in substance abuse treatment illustrates areas of concern in the overall status of women in substance abuse treatment.

Polychlorinated biphenyls and some organochlorine insecticides (DDT isomers and their metabolites, indane (..gamma..-BHC), dieldrin, heptachlor epoxide) were assessed in the serum of 17 women with recent missed abortions, 7 women who experienced one or several missed abortions in their past, and 7 women with normal, second trimester pregnancy. Fifty-three percent of the cases of recent missed abortion had PCB serum levels higher than the mean plus two standard deviations of the control group. The mean PCB serum level in women with recent missed abortion and relatively high PCB serum levels was significantly different from that of the control group (103.04more » versus 20.69 ppb,P<0.001). The mean PCB serum level of the former missed abortions group was also significantly different from that of the control group (82.00 versus 20.69 ppb, P<0.001). The quantity of the higher chlorinated biphenyl homologues (penta- and hexachlorobiphenyls) was increased in the high PCB level, missed abortion group and in the former missed abortion group, while the lower chlorinated biphenyl homologues were decreased in these groups in comparsion with the control group. The fact that the former missed abortion group showed increased PCB serum levels similar to those found in the high PCB level, recent missed abortion group confirms the existence of an association between relatively high PCB serum levels and the occurance of missed abortion.

Purpose This study assesses how well two cartoons transfer knowledge of principles of work disability prevention among stakeholders, according to their level of experience. We also document stakeholders' perceptions of the usefulness of the cartoons. Method We performed a descriptive study. Two groups of stakeholders were recruited: (1) experienced (working for more than 2 years in work disability), (2) non-experienced (in training). A self-administered questionnaire with open-ended questions documented stakeholders' understanding of each cartoon box and their perception of the possible usefulness of the cartoons. We transformed qualitative responses into quantitative responses for descriptive purposes. We performed independent t tests to compare the groups' level of understanding, and content analysis for the perception of usefulness. Results Overall, 149 stakeholders (50 experienced and 99 non-experienced) participated and identified 79.4 and 61.4 % of all principles presented in each of the two cartoons respectively. Experienced stakeholders identified more principles compared to non-experienced stakeholders (p = 0.007). Both cartoons were perceived to be useful for knowledge transfer. Conclusions Principles were generally well identified in the cartoons by all participants. Cartoons can be used as an effective tool among stakeholders to achieve a common understanding in order to coordinate their actions.

2011-02-01

The current study draws upon ecodevelopmental theory to identify protective and risk factors that may influence emotional distress during adolescence. Hierarchical regression analyses were used to examine the relationship among family obligations, school connectedness and emotional distress of 4,198 (51% female) middle and high school students who were primarily (59%) European American. The overall model explained 21.1% of the variance in student emotional distress. A significant interaction effect was found indicating that school connectedness moderated the relationship between family obligations and emotional distress. Specifically, for students with low to moderate levels of family obligations, a stronger sense of school connectedness was associated with lower emotional distress. The buffering effect of school connectedness was weakened as the level of family obligations increased and completely disappeared for students who experienced high levels of family obligations. The creation of a program that takes a holistic approach, in order to curtail the levels of highly emotionally distressed adolescents, must continue to address the ever changing demands that adolescents encounter and prepare youth to deal with functioning within multiple contexts and do so while maintaining emotional well-being.

2014-01-01

Despite high rates of unemployment, incarceration, violence, and suicide experienced by young Black men in America, research conducted in inner-city environments consistently report nonsignificant levels of depression among Black men. The unique history of social exclusion, stereotyping, and discrimination experienced by Black men has significant implications for the accurate assessment of depression. A review of significant historical and current sociological, educational, and legal-justice circumstances that affect the mental health of young Black men is presented. Barriers and limitations to traditional depression assessment and measurement is discussed and followed by recommendations for advancing knowledge of depression in young Black men. Research and practice that seeks to explore and explain sociocultural variances in traditional definitions of depression among young Black men will improve mental health, mental health outreach, and social function in this population.

Variations in gravitoinertial force level affect the gain of the vestibulo-ocular reflex - Implications of the etiology of space motion sickness

Recordings of horizontal nystagmus were obtained on 16 male subjects exposed to repeated patterns of horizontal angular acceleration, constant velocity rotation, and sudden-stop deceleration in the laboratory and in the free-fall and high-force periods of parabolic flight. Nystagmus intensity was a clear function of gravitoinertial force level: slow phase velocity and beat frequency increased during exposure to high force levels and decreased in free-fall compared to values obtained at 1 G. These findings indicate that the gain of the vestibulo-ocular reflex decreases in free-fall. This fact likely accounts for the disorientation and dizziness sometimes experienced by astronauts when moving their heads in the early phases of orbital flight and again after splashdown. The implications of the present findings, both for the etiology and for the treatment of space motion sickness, are discussed.

Accumulation and potential health effects of organohalogenated compounds in the arctic fox (Vulpes lagopus)--a review.

This review addresses biological effects of anthropogenic organohalogenated compounds in the arctic fox (Vulpes lagopus). When considering the current levels, spatial and tissue distributions of selected organic pollutants in arctic fox subpopulations, especially the Svalbard based populations accumulate high levels. The dominating contaminant groups are the polychlorinated biphenyls (PCBs) and chlordanes (CHLs), which reach high levels in adipose tissues, adrenals and liver. Recent controlled exposure studies on domesticated arctic fox and Greenland sledge dogs, show adverse health effects associated with OC concentrations lower than those measured in free-ranging populations. This indicates that especially populations at Svalbard may be at risk of experiencing OC related effects. The arctic fox as such may be an overlooked species in the Arctic Monitoring and Assessment Programs and it would add further information about pollution in the Arctic to include this species in the monitoring program.

Collective gatherings foster group cohesion through providing occasion for emotional sharing among participants. However, prior studies have failed to disentangle two processes that are involved in emotional sharing: 1) focusing shared attention on the same emotion-eliciting event and 2) actively sharing one’s experiences and disclosing one’s feelings to others. To date, it has remained untested if shared attention influences group cohesion independent of active emotional sharing. Our experiment investigated the effect of shared versus individual attention on cohesion in groups of strangers. We predicted that differences in group cohesion as called forth by shared vs. individual attention are most pronounced when experiencing highly arousing negative affect, in that the act of experiencing intensely negative affect with others buffers negative affect’s otherwise detrimental effect on group cohesion. Two-hundred sixteen participants were assembled in groups of 3 to 4 people to either watch an emotion-eliciting film simultaneously on a common screen or to watch the same emotion-eliciting film clip on a laptop in front of each group member using earphones. The film clips were chosen to elicit either highly arousing negative affect or one of three other affective states representing the other poles in Russel’s Circumplex model of affect. We examined self-reported affective and cognitive group cohesion and a behavioral measure of group cohesion. Results support our buffer-hypothesis, in that experiencing intense negative affect in unison leads to higher levels of group cohesion than experiencing this affect individually despite the group setting. The present study demonstrates that shared attention to intense negative emotional stimuli affects group cohesion independently of active emotional sharing. PMID:26335924

The challenges of caring in a technological environment: critical care nurses' experiences.

PubMed

McGrath, Mary

2008-04-01

This paper presents and discusses the findings from a phenomenological study which illuminated the lived experiences of experienced critical care nurses caring within a technological environment. While nursing practice is interwoven with technology, much of the literature in this area is speculative. Moreover, there is a debate as to whether and how 'high tech' and 'high touch' are reconcilable; this orientation is referred to as the optimism vs. pessimism debate. On a personal level, the motivation for this study came from the author's 13 years' experience in the critical care area. Following ethical approval, 10 experienced nurses from two cardiothoracic critical care units in Ireland participated in the study. A Heideggerian phenomenological methodology was used. Data collection consisted of unstructured interviews. A method of data analysis described by Walters was used. The findings provide research-based evidence to illuminate further the optimistic/pessimistic debate on technology in nursing. While the study demonstrates that the debate is far from resolved, it reveals a new finding: life-saving technology that supports the lives of critically ill patients can bring experienced nurses very close to their patients/families. The three main themes that emerged: 'alien environment', 'pulling together' and 'sharing the journey' were linked by a common thread of caring. Experienced critical care nurses are able to transcend the obtrusive nature of technology to deliver expert caring to their patients. However, the journey to proficiency in technology is very demanding and novice nurses have difficulty in caring with technology. Relevance to clinical practice. It is recommended that more emphasis be placed on supporting, assisting and educating inexperienced nurses in the critical care area and that the use of technology in nursing be given serious consideration.

Previous research into scratch card gambling has highlighted the effects of these games on players' arousal and affective states. Specifically, near-miss outcomes in scratch cards (uncovering 2 of 3 needed jackpot symbols) have been associated with high levels of physiological and subjective arousal and negative emotional evaluations, including increased frustration. We sought to extend this research by examining whether near-misses prompted increases in gambling urge, and the subsequent purchasing of additional scratch cards. Participants played two scratch cards with varying outcomes with half of the sample experiencing a near-miss for the jackpot prize, and the other half experiencing a regular loss. Players rated their urge to continue gambling after each game outcome, and following the initial playing phase, were then able to use their winnings to purchase additional cards. Our results indicated that near-misses increased the urge to gamble significantly more than regular losses, and urge to gamble in the near-miss group was significantly correlated with purchasing at least one additional card. Although some players in the loss group purchased another card, there was no correlation between urge to gamble and purchasing in this group. Additionally, participants in the near-miss group who purchased additional cards reported higher levels of urge than those who did not purchase more cards. This was not true for the loss group: participants who experienced solely losing outcomes reported similar levels of urge regardless of whether or not they purchased more scratch cards. Despite near-misses' objective status as monetary losses, the increased urge that follows near-miss outcomes may translate into further scratch card gambling for a subset of individuals .

Dating violence is a significant problem in Mexico. National survey data estimated 76 % of Mexican youth have been victims of psychological aggression in their relationships; 15.5 % have experienced physical violence; and 16.5 % of women have been the victims of sexual violence. Female adolescents perpetrate physical violence more frequently than males, while perpetration between genders of other types of violence is unclear. Furthermore, poor, marginalized youth are at a higher risk for experiencing dating violence. "Amor… pero del Bueno" (True Love) was piloted in two urban, low-income high schools in Mexico City to prevent dating violence. The intervention consisted of school-level and individual-level components delivered over 16 weeks covering topics on gender roles, dating violence, sexual rights, and strategies for coping with dating violence. The short-term impact was assessed quasi-experimentally, using matching techniques and fixed-effects models. A sample of 885 students (381 students exposed to the classroom-based curriculum of the individual-level component (SCC, IL-1) and 540 exposed only to the school climate component (SCC)) was evaluated for the following: changes in dating violence behaviors (psychological, physical and sexual), beliefs related to gender norms, knowledge, and skills for preventing dating violence. We found a 58 % (p < 0.05) and 55 % (p < 0.05) reduction in the prevalence of perpetrated and experienced psychological violence, respectively, among SCC, IL-1 males compared to males exposed only to the SCC component. We also found a significant reduction in beliefs and attitudes justifying sexism and violence in dating relationships among SCC, IL-1 females (6 %; p < 0.05) and males (7 %; p < 0.05).

AIDS stigmas delay HIV diagnosis, interfere with health care, and contribute to mental health problems among people living with HIV. While there are few studies of the geographical distribution of AIDS stigma, research suggests that AIDS stigmas are differentially experienced in rural and urban areas. We conducted computerized interviews with 696 men and women living with HIV in 113 different zip code areas that were classified as large-urban, small-urban, and rural areas in a southeast US state with high-HIV prevalence. Analyses conducted at the individual level (N = 696) accounting for clustering at the zip code level showed that internalized AIDS-related stigma (e.g., the sense of being inferior to others because of HIV) was experienced with greater magnitude in less densely populated communities. Multilevel models indicated that after adjusting for potential confounding factors, rural communities reported greater internalized AIDS-related stigma compared to large-urban areas and that small-urban areas indicated greater experiences of enacted stigma (e.g., discrimination) than large-urban areas. The associations between anticipated AIDS-related stigma (e.g., expecting discrimination) and population density at the community-level were not significant. Results suggest that people living in rural and small-urban settings experience greater AIDS-related internalized and enacted stigma than their counterparts living in large-urban centers. Research is needed to determine whether low-density population areas contribute to or are sought out by people who experienced greater AIDS-related stigma. Regardless of causal directions, interventions are needed to address AIDS-related stigma, especially among people in sparsely populated areas with limited resources.

Recalled first reactions to inhaling nicotine predict the level of physical dependence.

The level of physical dependence is a measure of addiction that correlates highly with addiction-associated changes in brain structure. We sought to determine whether age at first inhalation and initial reactions to inhaling nicotine are related to level of physical dependence in early adulthood. Young adults (n=312; mean age=24 years; 51% female) from the Nicotine Dependence in Teens study who had smoked at least once in the preceding three months completed self-report questionnaires in 2011-12. We assessed level of physical dependence with three validated self-report items assessing 'wanting,' 'craving' and 'needing' triggered by nicotine deprivation. Survey items assessed smoking behavior, including age at first inhalation, and recalled first reactions to inhaling nicotine. After adjusting for covariates, experiencing relaxation, heart racing/pounding, rush or "buzz" (OR=1.45; 95% CI: 1.08, 1.94) and dizziness (OR=1.58; 95% CI: 1.15, 2.18) at first nicotine inhalation were associated with an increased odds of being at a higher level of physical dependence in young adulthood; the association for experiencing relaxation (OR=1.78; 95% CI: 1.20, 2.64) and heart racing/pounding (OR=1.51; 95% CI: 1.00, 2.28) persisted after additionally controlling for all other first reactions. Neither age at first inhalation nor unpleasant first reactions predicted level of physical dependence. In accordance with prior research, our findings suggest that smokers who are particularly sensitive to the pleasant, "buzz-related" and generally arousing effects of nicotine may be more likely to attain higher levels of physical dependence.

High school and college biology: A multi-level model of the effects of high school biology courses on student academic performance in introductory college biology courses

NASA Astrophysics Data System (ADS)

Loehr, John Francis

The issue of student preparation for college study in science has been an ongoing concern for both college-bound students and educators of various levels. This study uses a national sample of college students enrolled in introductory biology courses to address the relationship between high school biology preparation and subsequent introductory college biology performance. Multi-Level Modeling was used to investigate the relationship between students' high school science and mathematics experiences and college biology performance. This analysis controls for student demographic and educational background factors along with factors associated with the college or university attended. The results indicated that high school course-taking and science instructional experiences have the largest impact on student achievement in the first introductory college biology course. In particular, enrollment in courses, such as high school Calculus and Advanced Placement (AP) Biology, along with biology course content that focuses on developing a deep understanding of the topics is found to be positively associated with student achievement in introductory college biology. On the other hand, experiencing high numbers of laboratory activities, demonstrations, and independent projects along with higher levels of laboratory freedom are associated with negative achievement. These findings are relevant to high school biology teachers, college students, their parents, and educators looking beyond the goal of high school graduation.

Chronic stress and sexual function in women.

PubMed

Hamilton, Lisa Dawn; Meston, Cindy M

2013-10-01

Chronic stress is known to have negative effects on reproduction, but little is known about how it affects the sexual response cycle. The present study examined the relationship between chronic stress and sexual arousal and the mechanisms that mediate this relationship. The aim of this study is to test the relationship between chronic stress and sexual arousal and identify mechanisms that may explain this relationship. We predicted that women experiencing high levels of chronic stress would show lower levels of genital arousal and dehydroepiandrosterone (DHEAS) and higher levels of cortisol and cognitive distraction compared with women with average levels of stress. Women who were categorized as high in chronic stress (high stress group; n=15) or average in chronic stress (average stress group; n=15) provided saliva samples and watched an erotic film while having their genital and psychological arousal measured. Main outcome measures were vaginal pulse amplitude, psychological arousal, salivary cortisol, salivary DHEAS, and heart rate and compared them between women with high and average levels of chronic stress. Women in the high stress group had lower levels of genital, but not psychological arousal, had higher levels of cortisol, and reported more distraction during the erotic film than women in the average stress group. The main predictor of decreased genital sexual arousal was participants' distraction scores. High levels of chronic stress were related to lower levels of genital sexual arousal. Both psychological (distraction) and hormonal (increased cortisol) factors were related to the lower levels of sexual arousal seen in women high in chronic stress, but distraction was the only significant predictor when controlling for other variables. © 2013 International Society for Sexual Medicine.

Fifteen years after parental divorce: mental health and experienced life-events.

PubMed

Angarne-Lindberg, Teresia; Wadsby, Marie

2009-01-01

The children who experienced their parents' divorce when the divorce rate in Sweden had begun to grow to higher levels than in preceding decades are today adults. The aim of this study was to investigate if adults who had experienced parental divorce 15 years before the time of our study, differed in mental health from those with continuously married parents, taking into account life events other than the divorce. Instruments used were the Symptom Checklist (SCL-90) measuring mental health and the Life Event questionnaire capturing the number and experience of occurred events. Forty-eight persons, who were 7-18 years old when their parents divorced, constituted the divorce group, and 48 persons matched on age, sex and growth environment formed the study groups. The SCL-90 showed a limited difference between the groups, but not concerning total mental health. A main finding was a difference with regard to sex and age; women aged 22-27 in the divorce group displayed poorer mental health than other participants in both groups. The results from the Life Event questionnaire showed that the divorce group had experienced a significantly larger number of events, and more life events were described as negative with difficult adjustment. A regression analysis showed a significant relation between the SCL-90, Global Severity Index and life events experienced as negative with difficult adjustment, divorce events excluded, but not with the divorce itself. It seems highly desirable to pay more attention than has thus far been paid to girls with experience of childhood divorce at age 7-12.

Harbour porpoises react to low levels of high frequency vessel noise

Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is the main contributor of anthropogenic noise underwater, but studies of shipping noise effects have primarily considered baleen whales due to their good hearing at low frequencies, where ships produce most noise power. Conversely, the possible effects of vessel noise on small toothed whales have been largely ignored due to their poor low-frequency hearing. Prompted by recent findings of energy at medium- to high-frequencies in vessel noise, we conducted an exposure study where the behaviour of four porpoises (Phocoena phocoena) in a net-pen was logged while they were exposed to 133 vessel passages. Using a multivariate generalised linear mixed-effects model, we show that low levels of high frequency components in vessel noise elicit strong, stereotyped behavioural responses in porpoises. Such low levels will routinely be experienced by porpoises in the wild at ranges of more than 1000 meters from vessels, suggesting that vessel noise is a, so far, largely overlooked, but substantial source of disturbance in shallow water areas with high densities of both porpoises and vessels.

This study investigated the association between literacy skills and self-reported health among Danish ( n = 7284), Finnish ( n = 5454), Norwegian ( n = 4942) and Swedish ( n = 4555) participants aged 16-65 years. Logistic regression models were used to assess the association between literacy skills and self-reported health after adjusting for sex, age and educational level. Nordic participants aged 16-65 years with literacy skills at the lowest level reported sub-optimal health more often (28-37%) than those with literacy skills at the highest level (7-9%). After adjusting for sex, age and educational level, the likelihood of reporting sub-optimal health was 1.99-3.24 times as high for those with literacy skills at the lowest level as for those with literacy skills at the highest level. These results suggest that poor literacy skills increase the likelihood of experiencing poor health in the Nordic countries, even after controlling for educational level.

Da Vinci© Skills Simulator™: is an early selection of talented console surgeons possible?

Meier, Mark; Horton, Kevin; John, Hubert

2016-12-01

To investigate whether the learning curve of robotic surgery simulator training depends on the probands' characteristics, such as age and prior experience, we conducted a study of six distinct proband groups, using the da Vinci Skills Simulator: experienced urological robotic surgeons, surgeons with experience as da Vinci tableside assistants, urological surgeons with laparoscopic experience, urological surgeons without laparoscopic experience, and complete novices aged 25 and younger and 40 and older. The results showed that all experienced robotic surgeons reached expert level (>90 %, as defined previously in the literature) within the first three repetitions and remained on a high level of performance. All other groups performed worse. Tableside assistants, laparoscopically experienced surgeons, and younger novices showed a better performance in all exercises than surgeons without laparoscopic experience and older novices. A linear mixed-effects model analysis demonstrated no significant difference in learning curves between proband groups in all exercises except the RW1 exercise for the younger proband group. In summary, we found that performance in robotic surgery, measured by performance scores in three virtual simulator modules using the EndoWrist techniques, was dependent on age and prior experience with robotic and laparoscopic surgery. However, and most importantly, the learning curve was not significantly affected by these factors. This suggests that the da Vinci Skills Simulator™ is a useful practice tool for everyone learning or performing robotic surgery, and that early selection of talented surgeons is neither possible nor necessary.

Mediators of the Relation Between Community Violence and Sexual Risk Behavior Among Adults Attending a Public Sexually Transmitted Infection Clinic.

Prior research shows that violence is associated with sexual risk behavior, but little is known about the relation between community violence (i.e., violence that is witnessed or experienced in one's neighborhood) and sexual risk behavior. To better understand contextual influences on HIV risk behavior, we asked 508 adult patients attending a publicly funded STI clinic in the U.S. (54 % male, M age = 27.93, 68 % African American) who were participating in a larger trial to complete a survey assessing exposure to community violence, sexual risk behavior, and potential mediators of the community violence-sexual risk behavior relation (i.e., mental health, substance use, and experiencing intimate partner violence). A separate sample of participants from the same trial completed measures of sexual behavior norms, which were aggregated to create measures of census tract sexual behavior norms. Data analyses controlling for socioeconomic status revealed that higher levels of community violence were associated with more sexual partners for men and with more episodes of unprotected sex with non-steady partners for women. For both men and women, substance use and mental health mediated the community violence-sexual risk behavior relation; in addition, for men only, experiencing intimate partner violence also mediated this relation. These results confirm that, for individuals living in communities with high levels of violence, sexual risk reduction interventions need to address intimate partner violence, substance use, and mental health to be optimally effective.

Introduction As people with a range of disabilities strive to increase their community mobility, occupational therapy driver assessors are increasingly required to make complex recommendations regarding fitness-to-drive. However, very little is known about how therapists use information to make decisions. The aim of this study was to model how experienced occupational therapy driver assessors weight and combine information when making fitness-to-drive recommendations and establish their level of decision agreement. Method Using Social Judgment Theory method, this study examined how 45 experienced occupational therapy driver assessors from the UK, Australia and New Zealand made fitness-to-drive recommendations for a series of 64 case scenarios. Participants completed the task on a dedicated website, and data were analysed using discriminant function analysis and an intraclass correlation coefficient. Results Accounting for 87% of the variance, the cues central to the fitness-to-drive recommendations made by assessors are the client’s physical skills, cognitive and perceptual skills, road law craft skills, vehicle handling skills and the number of driving instructor interventions. Agreement (consensus) between fitness-to-drive recommendations was very high: intraclass correlation coefficient = .97, 95% confidence interval .96–.98). Conclusion Findings can be used by both experienced and novice driver assessors to reflect on and strengthen the fitness-to-drive recommendations made to clients. PMID:26435572

To describe the perceived experiences of stigma and discrimination among people living with severe and persistent mental illness in assertive community treatment (ACT teams) settings in New South Wales (NSW), Australia. The Discrimination and Stigma Scale (DISC) was used in this cross-sectional study with people living with severe and persistent mental illness. The DISC is a reliable and valid, quantitative and qualitative instrument used to explore and measure levels of negative, anticipated and positive discrimination. Relevant clinical history and socio-demographic information were also collected. A total of 50 clients participated, with 40 (80%) reporting experienced negative discrimination in at least one life area. Negative discrimination was most commonly experienced in being avoided or shunned (n=25, 50%), by neighbours (n=24, 48%) and family (n=23, 46%). Anticipated discrimination was common, with half of participants (n=25, 50%) feeling the need to conceal their mental health diagnosis. Discrimination was highly prevalent in everyday aspects of life. While healthcare professionals often tend to increase perceived stigma and discrimination, this was only experienced in interactions with general health professionals, while interactions with ACT team members decreased perceived stigma and increased positive discrimination. This indicates that healthcare professionals potentially have a significant role in reducing stigma and discrimination in mental health and that such an effect may be optimised in an ACT team setting. © The Author(s) 2016.

2014-09-01

The head impact exposure experienced by football players at the college and high school levels has been well documented; however, there are limited data regarding youth football despite its dramatically larger population. The objective of this study was to investigate head impact exposure in middle school football. Impacts were monitored using a commercially available accelerometer array installed inside the helmets of 17 players aged 12-14 years. A total of 4678 impacts were measured, with an average (±standard deviation) of 275 ± 190 impacts per player. The average of impact distributions for each player had a median impact of 22 ± 2 g and 954 ± 122 rad/s², and a 95th percentile impact of 54 ± 9 g and 2525 ± 450 rad/s². Similar to the head impact exposure experienced by high school and collegiate players, these data show that middle school football players experience a greater number of head impacts during games than practices. There were no significant differences between median and 95th percentile head acceleration magnitudes experienced during games and practices; however, a larger number of impacts greater than 80 g occurred during games than during practices. Impacts to the front and back of the helmet were most common. Overall, these data are similar to high school and college data that have been collected using similar methods. These data have applications toward youth football helmet design, the development of strategies designed to limit head impact exposure, and child-specific brain injury criteria.

Research indicates that mirror therapy reduces phantom limb pain (PLP). Objectives were to determine when mirror therapy works in those who respond to treatment, the relevance of baseline PLP to when pain relief occurs, and what pain symptoms respond to mirror therapy. Data from two independent cohorts with unilateral lower limb amputation were analyzed for this study (n=33). Mirror therapy consisted of 15-min sessions in which amputees performed synchronous movements of the phantom and intact legs/feet. PLP was measured using a visual analogue scale and the Short-Form McGill Pain Questionnaire. The severity of PLP at the beginning of treatment predicted when pain relief occurred. Those with low baseline PLP experienced a reduction (p<0.05) in PLP by session 7 of treatment, those with medium baseline PLP experienced pain relief by session 14 of treatment, and those with high baseline PLP experienced pain relief by session 21 of treatment. Mirror therapy reduced throbbing, shooting, stabbing, sharp, cramping, aching, tender, splitting, tiring/exhausting, and punishing-cruel pain symptoms. The degree of PLP at baseline predicts when mirror therapy relieves pain. This article indicates that the degree of baseline PLP affects when mirror therapy relieves pain: relief occurs by session 7 in patients with low PLP but by session 21 in patients with high PLP. Clinicians should anticipate slower pain relief in patients who begin treatment with high levels of pain. ClinicalTrials.gov numbers:NCT00623818 and NCT00662415.

Social capital, the miniaturization of community and cannabis smoking among young adults.

Lindström, Martin

2004-06-01

The impact of social participation, trust and the miniaturization of community, i.e. the combination of high social participation and low trust, on cannabis smoking was investigated. The 2000 public health survey in Scania is a cross-sectional study. A total of 13,715 persons aged 18-80 years, of which 3,978 persons aged 18-34 years were included in this study, answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to investigate the association between the social capital variables and ever having experienced cannabis smoking. The multivariate analysis was performed to investigate the importance of possible confounders (age, country of origin and education) on the differences in having experienced cannabis smoking according to social participation, trust and their four combination categories. Cannabis smoking is not associated with social participation, but positively associated with low trust among both men and women, and the miniaturization of community, i.e. the combination of high social participation and low trust, among men. This study suggests that the miniaturization of community, i.e. the combination of high social participation and low levels of generalized trust of other people, may enhance the experience of cannabis smoking.

Abstract: Background: Given the significant health effects of domestic violence against women, the present study was conducted in 2016, in Tehran, Iran in order to compare the socioeconomic status, perceived social support and mental status in women of reproductive age experiencing and not experiencing domestic violence. Methods: This descriptive-analytical cross-sectional study was conducted on 500 women. The data collection tools used included questionnaires: demographic information, Socioeconomic, Beck’s Depression, Spielberger’s Anxiety, Cohen’s Perceived Stress, Sarason’s Perceived Social Support and WHO’s Domestic Violence Inventory. Results: The results showed that 43.2% of women said they had experienced at least one case of domestic violence, among which 16.4%, 15% and 36.6% of women had experienced physical, sexual and emotional-verbal types of violence, respectively. The mean age (p less than 0.001) and educational level (p=0/018) of violated women and their spouses (p less than 0.001) were lower than those of non-violated women. Furthermore, violated women experienced lower socioeconomic status (p less than 0.05), higher perceived stress (p less than 0.008), higher depression (p less than 0.001), and higher overt anxiety (0.002. They also perceived lower levels of social support (p less than 0.001). Conclusions: The issue of domestic violence was rather prevalent in the participants of the present study, particularly the younger, less educated and more socioeconomically deprived communities and families.

A total of 125 registered nurses participated in an investigation of Posttraumatic Stress Disorder (PTSD) related symptoms and various levels of nursing care. The sample included 43 emergency room nurses (ER), 51 intensive care unit nurses (ICU), and 31 general floor nurses (GF). All participants were assessed on measures of PTSD, social support, dissociation, anxiety, depression, and demographics. Contrary to expectations, the ER nurses were not found to be uniquely stressed by their work when compared to the other nursing groups. Results indicated that all nurses experienced a significant level of anxiety but were not in the clinically significant range for PTSD, depression, or dissociation. It was inferred that social support played a significant role in helping nurses cope with work-related stress. Nevertheless, the high anxiety levels of all nurses were highlighted as a concern. It was suggested that exposure to numerous traumatic experiences over a lifetime of nursing, and a lack of control over these experiences, contributed to the high anxiety levels seen in all nursing groups.

Early adolescence is marked by transitions for adolescents, and is also a time for identity exploration. Ethnic identity is an essential component of youths’ sense of self. In this study we examined the trajectories of ethnic identity for adolescents from ethnic minority backgrounds during a 4-year period. Six latent class trajectories were identified in the study: the majority of adolescents (41.8%) displayed growth in ethnic identity over 4 years, followed by 30.1% whose high levels of ethnic identity remained stable, then by those who experienced moderate decreases in ethnic identity (10.8 percent). Another class of adolescents (7.3%) showed significant declines in ethnic identity level, followed by 5.5% of adolescents with significant increases, and finally by 4.5% of adolescents with low stable levels of ethnic identity during this developmental period. The classes differed by ethnicity, and adolescents with increasing high levels of ethnic identity reported better parent–child relationships. Findings and implications are discussed. PMID:21787058

Parental incarceration can be devastating for families. Children may experience difficulties, and the stress on caregivers who take on unexpected childrearing is high. We implemented and evaluated a family-level intervention with caregivers and children experiencing parental (typically maternal) incarceration, in a community setting. We partnered with a community-based organization serving families with an incarcerated parent to conduct a pilot trial of the Strengthening Families Program (SFP). Process evaluation indicated high implementation fidelity, satisfaction, engagement, and attendance. Outcome evaluation results indicated positive changes in family-level functioning, caregivers’ positive parenting, and caregiver depression symptoms from pre- to post-intervention, with some changes retained at follow-up 4 months later. Implications for preventive interventions with children of incarcerated parents, and their caregivers, are discussed. PMID:24353363

Parental divorce and adult psychological distress: evidence from a national birth cohort: a research note.

PubMed

Rodgers, B; Power, C; Hope, S

1997-10-01

An association was found between childhood parental divorce and adult psychological distress in a British national birth cohort at ages 23 and 33. No moderating effects were found for gender, age at separation, or remarriage of the custodial parent. Participants who were young adults when their parents divorced also showed increased levels of symptomatology, whereas those who experienced parental death in childhood showed no increased risk. An interaction between parental divorce and own divorce in women, giving particularly high symptom levels, arose from a selection process in those from divorced families of origin only, with high 23-year scores predicting subsequent divorce. Own divorce was associated with an increase in distress between age 23 and 33, but this was irrespective of family of origin.

Transient rotordynamic analysis for the space-shuttle main engine high-pressure oxygen turbopump

1974-01-01

A simulation study was conducted to examine the transient rotordynamics of the space shuttle main engine (SSME) high pressure oxygen turbopump (HPOTP) with the objective of identifying, anticipating, and avoiding rotordynamic problem areas. Simulations were performed for steady state operations at emergency power levels and for critical speed transitions. No problems are indicated in steady state operation of the HPOTP emergency power levels, although the results indicated that a rubbing condition will be experienced during critical speed transition at shutdown, particularly involving rotor deceleration rate and imbalance distribution rubbing at the turbine floating-ring seals. The condition is correctable by either reducing the imbalance at the HPOTP hot gas turbine wheels, or by a more rapid deceleration of the rotor through it critical speed.

Experiences of restrictiveness in forensic psychiatric care: Systematic review and concept analysis.

PubMed

Tomlin, Jack; Bartlett, Peter; Völlm, Birgit

Mentally disordered offenders may be sent to secure psychiatric hospitals. These settings can resemble carceral spaces, employing high levels of security restricting resident autonomy, expression and social interaction. However, research exploring the restrictiveness of forensic settings is sparse. A systematic review was therefore undertaken to conceptualize this restrictiveness. Eight databases were searched for papers that address restrictive elements of secure forensic care in a non-cursory way. Fifty sources (empirical articles and policy documents) were included and subject to thematic analysis to identify 1) antecedent conditions to, 2) characteristic attributes, 3) consequences and 4) 'deviant' cases of the developing concept. The restrictiveness of forensic care was experienced across three levels: individual, institutional and systemic. Restrictiveness was subjective and included such disparate elements as limited leave and grounds access, ownership of personal belongings and staff attitudes. The manner and extent to which these are experienced as restrictive was influenced by two antecedent conditions; whether the purpose of forensic care was to be more caring or custodial and the extent to which residents were perceived to be risky. We argue that there must be a reflexivity from stakeholders between the level of restrictiveness needed to safely provide care in a therapeutic milieu and enable the maximum amount of resident autonomy.

Perceptions of biopsychosocial services needs among older adults with severe mental illness: met and unmet needs.

PubMed

Cummings, Sherry M; Cassie, Kimberly McClure

2008-05-01

This study sought to identify the psychiatric, physical, and social services needs experienced by older adults with severe mental illness (SMI) and to examine factors influencing their experience of need and service provision adequacy. Seventy-five older adults with SMI were recruited from a community mental health center to participate in the study. The typical client experienced a need for care in 10 areas, with the greatest needs occurring in the areas of psychological pain, physical illness, social contacts, looking after the home, and daily activities. The total number of unmet needs ranged from zero to 10, with the typical client having an average of 2.3 unmet needs (SD = 2.4). The highest proportions of unmet needs were in the areas of social contact, benefits, sight or hearing difficulties, and intimate relationships. Linear hierarchical regression analyses revealed that clients with lower income, greater impairments in independent daily living skills, and higher levels of depression experienced increased needs for care. Older clients who lived in private homes or apartments had higher levels of depression, and those who required assistance in the areas of intimate relationships and benefits experienced higher levels of unmet needs. Research and practice implications are discussed.

This study aimed to evaluate the possibility that differences in sensorimotor abilities exist between hitters and pitchers in a large cohort of baseball players of varying levels of experience. Secondary data analysis was performed on 9 sensorimotor tasks comprising the Nike Sensory Station assessment battery. Bayesian hierarchical regression modelling was applied to test for differences between pitchers and hitters in data from 566 baseball players (112 high school, 85 college, 369 professional) collected at 20 testing centres. Explanatory variables including height, handedness, eye dominance, concussion history, and player position were modelled along with age curves using basis regression splines. Regression analyses revealed better performance for hitters relative to pitchers at the professional level in the visual clarity and depth perception tasks, but these differences did not exist at the high school or college levels. No significant differences were observed in the other 7 measures of sensorimotor capabilities included in the test battery, and no systematic biases were found between the testing centres. These findings, indicating that professional-level hitters have better visual acuity and depth perception than professional-level pitchers, affirm the notion that highly experienced athletes have differing perceptual skills. Findings are discussed in relation to deliberate practice theory.

This study aimed to (1) identify benefit finding trajectories in cancer patients receiving psychological care; (2) examine associations of benefit finding trajectories with levels of and changes in psychological symptoms; and (3) examine whether socio-demographic and medical characteristics distinguished trajectories. Naturalistic longitudinal study design. Participants were 241 cancer patients receiving psychological care at specialized psycho-oncological institutions in the Netherlands. Data were collected before starting psychological care, and three and 9 months thereafter. Latent class growth analysis was performed to identify benefit finding trajectories. Five benefit finding trajectories were identified: 'high level-stable' (8%), 'very low level-small increase' (16%), 'low level-small increase' (39%), 'low level-large increase' (9%), and 'moderate level-stable' (28%). People in distinct benefit finding trajectories reported significant differential courses of depression but not of anxiety symptoms. Compared with the other four trajectories, people in the 'low level-large increase' trajectory reported the largest decreases in depression over time. Perceptions of cancer prognosis distinguished these trajectories, such that people with a favourable prognosis were more likely to belong to the 'high level-stable' trajectory, while people perceiving an uncertain prognosis were more likely to belong to the 'low level-large increase' trajectory of benefit finding. Cancer patients showed distinct benefit finding trajectories during psychological care. A small proportion reporting a large increase in benefit finding were also most likely to show decreases in depressive symptoms over time. These findings suggest a relation between perceiving benefits from cancer experience and improved psychological functioning in cancer patients receiving psychological care. Statement of contribution What is already known on this subject? People vary in course of benefit finding (BF) after trauma, with some experiencing enhanced BF and others decreased BF. Empirical studies have identified subgroups of cancer patients with distinct BF trajectories. What does this study add? This is the first study showing that cancer patients followed different BF trajectories during psychological care. Only a small proportion experienced clinically meaningful increases in BF over time. More attention is needed for cancer patients with decreased BF, as they are at a higher risk of remaining depressed. © 2017 The British Psychological Society.

2014-06-01

This article describes the socio-demographic characteristics of a sample of gay men in three cities in Chile, as well as experience with homophobia and subjective well-being. Snowball sampling was used to interview 325 gay men. The main findings included high levels of perceived discrimination and victimization, but interviewees reported higher levels of social well-being compared to studies elsewhere in the country. Age was related to differences in levels of social well-being, but not other variables. Individuals with university education reported higher levels of victimization and greater impact of discrimination on their lives. Gay men in Santiago reported a higher relative impact from incidents of aggression, but better levels of social well-being and happiness compared to those in other regions of Chile.

Actor-partner effects associated with experiencing intimate partner violence or coercion among male couples enrolled in an HIV prevention trial

PubMed Central

2014-01-01

Background Intimate partner violence (IPV) and coercion have been associated with negative health outcomes, including increased HIV risk behaviors, among men who have sex with men (MSM). This is the first study to describe the prevalence and factors associated with experiencing IPV or coercion among US MSM dyads using the actor-partner interdependence model (APIM), an analytic framework to describe interdependent outcomes within dyads. Methods Among MSM couples enrolled as dyads in an HIV prevention randomized controlled trial (RCT), two outcomes are examined in this cross-sectional analysis: 1) the actor experiencing physical or sexual IPV from the study partner in the past 3-months and 2) the actor feeling coerced to participate in the RCT by the study partner. Two multilevel APIM logistic regression models evaluated the association between each outcome and actor, partner, and dyad-level factors. Results Of 190 individuals (95 MSM couples), 14 reported experiencing physical or sexual IPV from their study partner in the past 3 months (7.3%) and 12 reported feeling coerced to participate in the RCT by their study partner (6.3%). Results of multivariate APIM analyses indicated that reporting experienced IPV was associated (p < 0.1) with non-Black/African American actor race, lower actor education, and lower partner education. Reporting experienced coercion was associated (p < 0.1) with younger actor age and lower partner education. Conclusions These findings from an HIV prevention RCT for MSM show considerable levels of IPV experienced in the past 3-months and coercion to participate in the research study, indicating the need for screening tools and support services for these behaviors. The identification of factors associated with IPV and coercion demonstrate the importance of considering actor and partner effects, as well as dyadic-level effects, to improve development of screening tools and support services for these outcomes.

Professional burnout has been described as a gradual erosion of a person and may be one of the possible consequences of chronic occupational stress. Although occupational stress has been surveyed among dentists in Hong Kong, no study has been published about burnout in the profession. This study aimed to evaluate burnout among Hong Kong dentists and its association with occupational stress. We surveyed a random sample of 1086 registered dentists in Hong Kong, which formed 50% of the local profession. They were mailed an anonymous questionnaire about burnout and occupational stress in 2015. The questionnaire assessed occupational stress, coping strategies, effects of stress, level of burnout, and socio-demographic characteristics of the respondents. Occupational stress assessment concerned 33 stressors in five groups: patient-related, time-related, income-related, job-related, and staff-/technically related. Level of burnout was assessed by the Maslach Burnout Inventory-Human Services Survey (22 items) with three scores: emotional exhaustion, depersonalisation, and personal accomplishment. Completed questionnaires were received from 301 dentists (response rate, 28.3%), of whom 25.4% had a high level of emotional exhaustion, 17.2% had a high level of depersonalisation, and 39.0% had a low level of personal accomplishment. Only 7.0% of respondents, however, had a high level of overall burnout (high emotional exhaustion, high depersonalisation, and low personal accomplishment). A high level of overall burnout was significantly associated with a higher mean score for job-related stressors and lack of postgraduate qualifications (P<0.05). Patient-related stressors are the top occupational stressors experienced by dentists in Hong Kong. In spite of this, a low proportion of dentists have a high level of overall burnout. There was a positive association between occupational stress and level of burnout.

Despite a relatively high rate of suicide associated with cancer, this issue has not been explored in Korean patients. This study investigates the prevalence and factors related to 'the desire for hastened death' (DHD) in Korean cancer patients. A cross-sectional survey using standardised measures, including the Schedule of Attitudes toward Hastened Death and the Hospital Anxiety and Depression Scale, was performed with 131 patients with different types of cancer. 13.7% of the participants experienced moderate DHD (Schedule of Attitudes toward Hastened Death scores 5-9) and 1.7% experienced high DHD (≥10). Socio-demographic and disease-associated factors of the DHD included age, overall health and shortness of breath. The majority of psychosocial variables such as sadness, distress, 'helplessness/hopelessness' and 'anxious preoccupation' had a moderate association with DHD. Patients with a clinically significant level of anxiety or depression reported higher levels of DHD. Other significant correlates included 'meaning/peace', a sense of burdening family, dignity impairment and suicidal thoughts after diagnosis. Helplessness/hopelessness and anxiety were the strongest predictors of DHD in multivariate analysis. In view of significant role of helplessness/hopelessness and anxiety in the DHD of cancer patients, careful monitoring and management of these factors should be an integral part of cancer care to reduce the occurrence of DHD. © 2010 Blackwell Publishing Ltd.

The effect of light level, CO2 flow rate, and anesthesia on the stress response of mice during CO2 euthanasia.

Euthanasia protocols are designed to mitigate the stress experienced by animals, and an environment that induces minimal stress helps achieve that goal. A protocol that is efficient and practical in a typical animal research facility is also important. Light intensity, isoflurane, and CO2 flow rate were studied for their impact on the stress response of mice during CO2 euthanasia. Behavior was observed and scored during euthanasia and serum corticosterone was measured immediately after death. Unsurprisingly, animals euthanized with a high-flow rate of CO2 became unconscious in the least amount of time, while animals euthanized with a low-flow rate required the most time to reach unconsciousness. There was a significant increase in anxious behaviors in animals in the isoflurane group (F1,12 = 6.67, P = 0.024), the high-flow rate CO2 group (F1,12 = 10.24, P = 0.007), and bright chamber group (F1,12 = 7.27, P = 0.019). Serum corticosterone was highest in the isoflurane group (124.72 ± 83.98 ng/ml), however there was no significant difference in corticosterone levels observed for the other study variables of light and flow-rate. A darkened chamber and low CO2 flow rates help to decrease stress experienced during CO2 euthanasia, while the use of isoflurane was observed to increase the stress response during euthanasia.

Refugees are one of the most vulnerable groups in Australian society, presenting high levels of exposure to traumatic events and consequently high levels of severe psychological distress. While there is a need for professional help, only a small percentage will receive appropriate care for their mental health concerns. This study aimed to determine cultural considerations required when providing mental health first aid to Iraqi refugees experiencing mental health problems or crises. Using a Delphi method, 16 experts were presented with statements about possible culturally-appropriate first aid actions via questionnaires and were encouraged to suggest additional actions not covered by the questionnaire content. Statements were accepted for inclusion in a guideline if they were endorsed by ≥90 % of panellists as 'Essential' or 'Important'. From a total of 65 statements, 38 were endorsed (17 for cultural awareness, 12 for cross-cultural communication, 7 for stigma associated with mental health problems, and 2 for barriers to seeking professional help). Experts were able to reach consensus about how to provide culturally-appropriate first aid for mental health problems to Iraqi refugees, demonstrating the suitability of this methodology in developing cultural considerations guidelines. This specific refugee study provided potentially valuable cultural knowledge required to better equip members of the Australian public on how to respond to and assist Iraqi refugees experiencing mental health problems or crises.

Evaluations of alcohol consequences moderate social anxiety risk for problematic drinking.

PubMed

Nitka, Danit; O'Connor, Roisin M

2017-02-01

The link between social anxiety (SA) and problematic drinking is complex; this seems predominantly true among young adults. Individuals high on SA are thought to be particularly sensitive to the negative effects of alcohol, which should deter them from drinking. Yet, some evidence suggests that those high on SA continue to drink despite experiencing negative alcohol-related consequences (NACs) (Morris, Stewart, & Ham, 2005). Although traditionally, researchers assume NACs are perceived as averse, emerging evidence suggests these are not categorically viewed as negative by undergraduates. The study goal was to test whether evaluations of NACs moderate the effect of SA on problematic drinking. It was hypothesized that high SA would predict elevated alcohol use and number of NACs experienced, but only for those who evaluate NACs as less negative. Undergraduate drinkers (N=130, 80 women) completed self-reports of social anxiety, NAC evaluations (ratings of how 'bad' experiencing each alcohol-related consequence would be), alcohol use, and NACs experienced. Regression analyses revealed that NAC evaluations moderated the effect of SA on number of NACs experienced, but not the effect of SA on weekly alcohol use. Simple slopes analyses showed that high SA was associated with elevated NACs experienced for those with weak negative NAC evaluations, controlling for alcohol use. These findings help explain the mixed SA-problematic drinking literature by identifying perceptions of NACs as an important moderator of SA risk for experiencing NACs. Moreover, clinical interventions aimed at reducing SA risk for undergraduate problematic drinking may benefit from targeting NAC evaluations. Copyright © 2016 Elsevier Ltd. All rights reserved.

Racial discrimination denies those from racial and ethnic minority backgrounds access to rights such as the ability to participate equally and freely in community and public life, equitable service provision and freedom from violence. Our study was designed to examine how people from racial and ethnic minority backgrounds in four Australian localities experience and respond to racial discrimination, as well as associated health impacts. Data were collected from 1,139 Australians regarding types of racial discrimination experienced, settings for these incidents, response mechanisms and psychological distress as measured by the Kessler 6 (K6) Psychological Distress Scale. Age, education, religion, gender, visibility and rurality were all significantly associated with differences in the frequency of experiencing racial discrimination. Experiencing racial discrimination was associated with worse mental health. Mental health impacts were not associated with the type of discriminatory experience, but experiencing racial discrimination in shops and in employment and government settings was associated with being above the threshold for high or very high psychological distress. One out of twelve response mechanisms was found to be associated with lower stress following a discriminatory incident. Study results indicate that poorer mental health was associated with the volume of discrimination experienced, rather than the type of experience. However, the impact of experiencing discrimination in some settings was shown to be particularly associated with high or very high psychological distress. Our findings suggest that interventions designed to prevent the occurrence of racism have more potential to increase mental health in racial and ethnic minority communities than interventions that work with individuals in response to experiencing racism.

Mineralogy and composition of matrix and chondrule rims in carbonaceous chondrites

1993-01-01

The degree of compositional variation of fine-grained minerals displayed by the members within any carbonaceous chondrite group (i.e., CI, CM, CV, CR) is a direct reflection of the range of aqueous alteration assemblages present. Matrix and fine-grained chondrule rims within any particular carbonaceous chondrite are mineralogically nearly identical to one another, but not necessarily similar in bulk elemental composition, even though they have subsequently experienced postaccretional secondary processing (aqueous alteration) under identical conditions. We propose that CO chondrites experienced parent body conditions of low f(O2), low water/rock ratios, and temperatures below 50 C. CR chondrites experienced higher water/rock ratios, potentially higher temperatures (not above 150 C), and a wide range of f(O2). The alteration mineralogy of CV chondrites indicates water/rock ratios at the high end (at least) of the range for CR chondrites, Essebi, and MAC 87300. CM chondrites experienced temperatures below 50 C, low f(O2) and low water/rock ratios, except EET 83334, which probably experienced relatively higher f(O2), and B-7904 and Y-86720, which experienced postalteration temperatures in the range 500-700 C. Most CI chondrites experienced temperatures between 50 and 150 C, relatively high water/rock ratios, and variable f(O2). Y-82162 witnessed postalteration heating, possibly as high as 400 C.

Several studies have reported significantly higher stress levels, both short and long terms, among mothers giving preterm birth compared with mothers giving birth at term. Stress, however, is a psychological phenomenon that may present as anxiety, depression and/or trauma reactions. In this study, the long-term mental health outcomes and the prevalence of anxiety, depression and trauma reactions in women experiencing preterm birth were explored. Interactional, main effect variables and predictors were identified. Twenty-nine mothers of 35 premature children born before the 33rd week of pregnancy were assessed within 2 weeks postpartum (T0), 2 weeks after hospitalization (T1), 6 months post-term (T2), and 18 months post-term (T3). The standardized psychometric methods Impact of Event Scale (IES), General Health Questionnaire (GHQ) and State Anxiety Inventory (STAI-X1) assessed the maternal mental health outcomes. The maternal mental health problems except state anxiety decreased from T0 to T1, but remained high and stable at T3. The prevalence of posttraumatic stress reactions (PTSR) and posttraumatic stress disorder (PTSD) at T0 and T3 was 52% and 23%, respectively. We identified the time period between T0 and T1 to have a significant main effect on mental health outcomes. The predictors of higher levels of mental health problems were preeclampsia, previous psychological treatment, age, trait anxiety and infant's postnatal intraventricular haemorrhage. Bleeding in pregnancy predicted lower levels of mental health problems. The prevalence of maternal mental health problems remained high, emphasizing the importance of effective interventions.

Mentoring relationships and the levels of role conflict and role ambiguity experienced by novice nursing faculty.

2013-01-01

This study explored the effect of mentoring on the levels of role conflict and role ambiguity experienced by novice nursing faculty related to their transitions into academe using a descriptive, comparative design. It also measured the relationship between the quality of mentoring experiences of novice nursing faculty and their levels of role conflict and role ambiguity using a correlational design. P. Benner's (1984) novice to expert model was utilized as a framework for successful role transition. J. R. Rizzo, R. J. House, and S. I. Lirtzman's (1970) role conflict and role ambiguity scale was used to measure the levels of role conflict and role ambiguity experienced by novice nursing faculty. Results indicate that participants (n = 224) who were mentored have significantly lower levels of role conflict (M = 3.57) and role ambiguity (M = 3.02) than those who were not mentored (M = 4.62 and M = 3.90, respectively). Also significant, the higher the participants' reported levels of quality of mentoring experiences were, the lower their levels of role conflict and role ambiguity were. The results of this study indicate that mentoring eases the transition of novice nursing faculty from practice into academe by decreasing the degree of role ambiguity and role conflict that they experience. © 2013.

2015-02-01

The aim of this study was to examine the relationship between stress and food selection patterns by sex among first-year undergraduate students studying in an Australian university. Participating in this cross-sectional study were 728 (331 men and 397 female students) first-year students, ages >18 y, attending the Gold Coast Campus of Griffith University. Data were collected using a self-administered questionnaire consisting of three sections: sociodemographic information, stress measures, and a 7-d food frequency questionnaire. More than half (52.9%) of the participants were found to suffer from some level of stress, with relatively more female students (57.4%) suffering than men (47.4%). Men who experienced mild to moderate levels of stress were two to three times more likely to eat cereal foods (P < 0.01), fish/seafood (P < 0.001), and protein powder (P < 0.05). They also tended to eat more meat alternatives (P < 0.05), highly processed foods (P < 0.05), and to drink more alcohol (P < 0.05) than unstressed male students. However, they were less likely to consume vegetables and fruit (P < 0.05) compared with their unstressed counterparts. The trend analysis results indicated significant dose-response patterns in the relationship between stress level and consumption of cereal food, meat alternatives, vegetables and fruit (negative trend), highly processed food, protein powder, beverages and alcoholic beverages (all P < 0.05). Female students who experienced mild to moderate stress were 2.22 times more likely to eat processed food (P < 0.01) than unstressed female students. Female students who experienced severe stress were less likely to consume meat alternatives (P < 0.05) than their unstressed counterparts. Significant dose-response trends were found in the relationship between stress levels and the consumption of meat alternatives, vegetables and fruit (both negative trends), and processed food (all P < 0.01). These results demonstrate a clear difference in food selection patterns between stressed male and female students, with stress being a more significant predictor of unhealthy food selection among male students. Further research is needed using a qualitative approach to understand how stress and eating behavior are related in university students. Copyright © 2015 Elsevier Inc. All rights reserved.

2005-03-01

The contextual interference (CI) effect has been investigated through practice schedule manipulations within both basic and applied studies. Despite extensive research activity there is little conclusive evidence regarding the optimal practice structure of real world manipulative tasks in professional training settings. The present study therefore assessed the efficacy of practising simple and complex knot-tying skills in professional fire-fighters training. Forty-eight participants were quasi-randomly assigned to various practice schedules along the CI continuum. Twenty-four participants were students selected for their novice knot-tying capabilities and 24 were experienced fire-fighters who were more 'experienced knot-tiers'. They were assessed for skill acquisition, retention and transfer effects having practiced tying knots classified as simple or complex. Surprisingly, high levels of CI scheduling enhance learning for novices even when practising a complex task. The findings also revealed that CI benefits are most apparent as learners engage in tasks high in transfer distality. In conclusion, complexity and experience are mediating factors influencing the potency of the CI training effect in real-world settings.

Previous studies have found significant stressors experienced by nurses working in haemodialysis units yet renal nurses appear to report less burnout than other nurses. This study aims to undertake an inductive process to better understand the stressors and the coping strategies used by renal nurses that may lead to resilience. Sixteen haemodialysis nurses from a metropolitan Australian hospital and two satellite units participated in open-ended interviews. Data were analysed from a grounded theory methodology. Measures of burnout and resilience were also obtained. Two major categories of stressors emerged. First, due to prolonged patient contact, family-like relationships developed that lead to the blurring of boundaries. Second, participants experienced discrimination from both patients and staff. Despite these stressors, the majority of participants reported low burnout and moderately high-to-high levels of resilience. The major coping strategy that appeared to promote resilience was emotional distancing, while emotional detachment appeared to promote burn-out. Assisting nurses to use emotional distancing, rather than emotional detachment strategies to engender a sense of personal achievement may promote resilience. 2012 European Dialysis and Transplant Nurses Association/European Renal Care Association

Nurses are at high risk of incurring workplace violence during their working life. This paper reports the findings on a cross-sectional, descriptive, self-report, postal survey in 2007. A stratified random sample of 3000 of the 29 789 members of the Queensland Nurses Union employed in the public, private and aged care sectors resulted in 1192 responses (39.7%). This paper reports the differences: between those nurses who experienced workplace violence and those who did not; across employment sectors. The incidence of workplace violence is highest in public sector nursing. Patients/clients/residents were the major perpetrators of workplace violence and the existence of a workplace policy did not decrease levels of workplace violence. Nurses providing clinical care in the private and aged care sectors experienced more workplace violence than more senior nurses. Although workplace violence was associated with high work stress, teamwork and a supportive workplace mitigated workplace violence. The perception of workplace safety was inversely related to workplace violence. With the exception of public sector nursing, nurses reported an inverse relationship with workplace violence and morale.

The epidemiology of physical attack and rape among crack-using women.

2001-02-01

This prospective study examines the epidemiology of physical attack and rape among a sample of 171 not-in-treatment, crack-cocaine using women. Since initiating crack use, 62% of the women reported suffering a physical attack. The annual rate of victimization by physical attack was 45%. Overall, more than half of the victims sought medical care subsequent to an attack. The prevalence of rape since crack use was initiated was 32%, and the annual rate was 11%. Among those women having been raped since they initiated crack use, 83% reported they were high on crack when the crime occurred as were an estimated 57% of the perpetrators. Logistic regression analyses showed that duration of crack use, arrest for prostitution, and some college education were predictors of having experienced a physical attack. Duration of crack use and a history of prostitution were predictors of suffering a rape. Drug abuse treatment programs must be sensitive to high levels of violence victimization experienced by crack-cocaine using women. Screening women for victimization, and treating the problems that emanate from it, may help make drug abuse treatment more effective.

Adolescent student-athletes face time constraints due to athletic and scholastic commitments, resulting in habitually shortened nocturnal sleep durations. However, there is a dearth of research on the effects of sleep debt on student-athlete performance. The study aimed to (i) examine the habitual sleep patterns (actigraphy) of high-level student-athletes during a week of training and academic activities, (ii) ascertain the effects of habitual sleep durations experienced by high-level student-athletes on psychomotor performance, and (iii) examine the impact of sport training intensities on the sleep patterns of high-level student-athletes that participate in low and high intensity sports. Sleep patterns of 29 high-level student-athletes (14.7 ± 1.3 yrs) were monitored over 7 days. A psychomotor vigilance task was administered on weekdays to ascertain the effects of habitual sleep durations. Weekend total sleep time was longer than weekdays along with a delay in bedtime, and waketimes. Psychomotor vigilance reaction times on Monday were faster than on Thursday and Friday, with reaction times on Tuesday also faster than on Friday. False starts and lapses were greater on Friday compared with Monday. There was a negative impact of sleep debt on student-athletes' psychomotor performance.

The purpose of this study was to examine the effects of listening to high-uplifting or low-uplifting music after a stressful task on (a) immune functions, (b) neuroendocrine responses, and (c) emotional states in college students. Musical selections that were evaluated as high-uplifting or low-uplifting by Japanese college students were used as musical stimuli. Eighteen Japanese subjects performed stressful tasks before they experienced each of these experimental conditions: (a) high-uplifting music, (b) low-uplifting music, and (c) silence. Subjects' emotional states, the Secretory IgA (S-IgA) level, active natural killer (NK) cell level, the numbers of T lymphocyte CD4+, CD8+, CD16+, dopamine, norepinephrine, and epinephrine levels were measured before and after each experimental condition. Results indicated low-uplifting music had a trend of increasing a sense of well-being. High-uplifting music showed trends of increasing the norepinephrine level, liveliness, and decreasing depression. Active NK cells were decreased after 20 min of silence. Results of the study were inconclusive, but high-uplifting and low-uplifting music had different effects on immune, neuroendocrine, and psychological responses. Classification of music is important to research that examines the effects of music on these responses. Recommendations for future research are discussed.

This study examined the moderating effect of employee hostility on the association of unit-level resident characteristics (depression and behavioral problems) to individual-level employee's resident-related stress and psychological well-being during 1-year follow-up study among 501 employees in elderly care. Our results showed that employee hostility was associated with decreased psychological well-being. In addition, hostility moderated the association between unit-level proportion of depressive residents and resident-related stress experienced by the individual employees. Hostile employees reported increased resident-related stress irrespective of the proportion of depressed residents in the unit. Instead, nonhostile employees were sensitive to the depression in the unit. They reported low levels of stress when depression levels in the unit were low and increased stress when depression levels were high. (c) 2006 APA, all rights reserved.

Using daily diary data, this study examined the associations between positive and negative parent-youth experiences and youth cortisol and physical health symptoms among a sample of adolescents (N=132, Mean Age = 13.39). On days when girls reported more negative experiences than usual, they exhibited more physical health symptoms and flatter evening cortisol slopes than usual. Negative experiences with mothers were associated with higher dinner and bedtime youth cortisol levels (between-person). Daily positive experiences with fathers were linked with lower dinner cortisol levels. Youth with high levels of negative experiences, on average, were less sensitive to daily variation in negative experiences than youth who experienced lower parental negativity. We discuss the benefits of a daily diary approach. PMID:27231418

Gaze Control in One Versus One Defensive Situations in Soccer Players With Various Levels of Expertise.

2016-12-01

Experienced and less experienced soccer players were compared in terms of their gaze behavior (number of fixations, fixation duration, number of fixation regions, and distribution of fixations across specific regions) during frontal 1 vs. 1 defensive situations. Twenty-four men (eight experienced soccer players, eight less experienced players and eight non-players) watched 20 video clips. Gaze behavior was registered with an Eye Tracking System. The video scenes were analyzed frame-by-frame. Significant main effect of the group (experience) was observed for the number of fixation regions. Experienced soccer players had a lower number of fixation regions than the non-soccer players. Moreover, the former group presented with significantly larger percentage of fixations in the ball/foot region. These findings suggest that experienced players may use a more efficient search strategy than novices, involving fixation on a lesser number of areas in specific locations. © The Author(s) 2016.

Burnout and Doctors: Prevalence, Prevention and Intervention

PubMed Central

Kumar, Shailesh

2016-01-01

Doctors are exposed to high levels of stress in the course of their profession and are particularly susceptible to experiencing burnout. Burnout has far-reaching implications on doctors; patients and the healthcare system. Doctors experiencing burnout are reported to be at a higher risk of making poor decisions; display hostile attitude toward patients; make more medical errors; and have difficult relationships with co-workers. Burnout among doctors also increases risk of depression; anxiety; sleep disturbances; fatigue; alcohol and drug misuse; marital dysfunction; premature retirement and perhaps most seriously suicide. Sources of stress in medical practice may range from the emotions arising in the context of patient care to the environment in which doctors practice. The extent of burnout may vary depending on the practice setting; speciality and changing work environment. Understanding dynamic risk factors associated with burnout may help us develop strategies for preventing and treating burnout. Some of these strategies will be reviewed in this paper. PMID:27417625

2007-01-01

This study was carried out to evaluate the herb usage among patients attending secondary health facilities in Southwestern Nigeria. Data including allergies to drug and herbs, use of social drugs, and herbs and their perceived efficacy to herbs was collected from 265 patients (inpatients n = 65; outpatients n = 200) using structured questionnaire and patients' drug charts. A total of 15.4% of inpatients were found to be using herbs that may be potentially harmful due to drug-drug/drug-herb interactions. Nine percent experienced adverse effects with the use of herbs, whereas 2% experienced adverse reactions on coadministration with prescribed drugs. A high percent of outpatients, 38%, were using alcoholic beverages for extracting the plant materials themselves. The study showed that the use of herbs with drugs is widely practiced among patients attending secondary health care facilities in Nigeria, usually without the doctor or pharmacist's knowledge.

Autobiographical memory sources of threats in dreams.

2018-02-01

Temporal sources of dream threats were examined through the paradigm of the Threat Simulation Theory. Two groups of young adults (18-24 years old), who did not experience severe threatening events in the year preceding their dream and reported a dream either with or without threats, were included. Participants (N = 119) kept a log of daily activities and a dream diary, indicating whether dream components referred to past experiences. The occurrence of oneiric threats correlated with the reporting of threats in the daily logs, their average severity, and the stress level experienced the day preceding the dream. The group whose dreams contained threats had significantly more references to temporal categories beyond one year than the group with dreams without threats. Our findings suggest that in the absence of recent highly negative emotional experiences, the threat simulation system selects memory traces of threatening events experienced in the past.

2013-04-01

Nursing home (NH) residents with dementia continue to receive inadequate pain treatment. The purpose of this qualitative study was to examine how nurses make decisions to pharmacologically treat pain in NH residents with dementia. Using Grounded Dimensional Analysis, 15 in-depth interviews were conducted with 13 nurses from four skilled nursing facilities in Wisconsin. Nurses experienced varying levels of certainty regarding suspected pain in response to particular resident characteristics and whether pain was perceived as visible/obvious or nonvisible/not obvious. Nurses felt highly uncertain about pain in residents with dementia. Suspected pain in residents with dementia was nearly always conceptualized as a change in behavior to which nurses responded by trialing multiple interventions in attempts to return the resident to baseline, which despite current recommendations, did not include pain relief trials. Residents with dementia were described as being at greatest risk for experiencing underassessment, undertreatment, and delayed treatment for pain Copyright 2013, SLACK Incorporated.

The Effect of Authentic Leadership, Person-Job Fit, and Civility Norms on New Graduate Nurses' Experiences of Coworker Incivility and Burnout.

This study examined the influence of authentic leadership, person-job fit with 6 areas of worklife, and civility norms on coworker incivility and burnout among new graduate nurses. New graduate nurses report experiencing high levels of workplace incivility from coworkers, which has been found to negatively impact their job and career satisfaction and increase their intention to leave. The role of civility norms in preventing burnout and subsequent exposure to incivility from coworkers has yet to be examined among new graduate nurses. A cross-sectional mail survey of 993 new graduate nurses across Canada was conducted. The results supported the hypothesized relationships between study variables. Civility norms play a key role in preventing early career burnout and coworker incivility experienced by new graduate nurses. Leaders can influence civility norms by engaging in authentic leadership behaviors and optimizing person-job fit.

Could high salinity be used to control bullfrogs in small ponds?

Ward, David L.; Finch, Colton; Blasius, Heidi

2015-01-01

We examined survival of bullfrog (Rana catesbeiana) eggs and tadpoles at 3 ppt and 6 ppt salinity in the laboratory to determine if low-level salinity could be used to eradicate bullfrogs from small ponds that contain native fishes. Bullfrog eggs and tadpoles <10 days old experienced 100% mortality when held at 6 ppt salinity for 10 days. Bullfrog tadpoles 10–15 days old experienced significantly reduced survival when exposed to salinity of 6 ppt for 10 days. Older bullfrog tadpoles (>9 months old) appeared unaffected by 14 days of 6 ppt salinity. Salinity of 3 ppt did not impact survival of bullfrog tadpole eggs or tadpoles at any of the life stages we tested. Adding salt to ponds in the early spring to increase salinity to 6 ppt may be a cost effective way to eradicate bullfrogs from small ponds without harming native fishes.

Obstructive sleep apnoea is the most common form of sleep-disordered breathing in adults and children. It is associated with many adverse health consequences. The objectives this study were to determine the prevalence, awareness and reporting of symptoms of obstructive sleep apnoea among hospitalized adult patients in Nigeria. This was a multicenter cross-sectional study involving 1420 adult patients admitted to general medical and surgical wards of selected hospitals from March to April 2013. A questionnaire embedded with Berlin questionnaire, Epworth sleepiness scale and questions on level of awareness and reporting of symptoms of sleep apnoea was used for data collection. One-third of the patients (33.4%) reported snoring, 16.3% had excessive daytime sleepiness, 10.0% experienced daytime fatigue, and 8.0% experienced drowsy driving. Approximately 5% reported witnessed apnoea and 18.0% had high risks for obstructive sleep apnoea. The frequency of high risk for sleep apnoea increased with age and declined after 65 years and also increased with the body mass index. Snoring, excessive daytime sleepiness and high risk for obstructive sleep apnoea were more common in patients with chronic medical conditions and who were admitted to the urban hospitals. The majority were not aware that snoring (77.3%) and excessive daytime sleepiness (65.8%) constitute a medical problem, and only 4.5% reported these symptoms to their doctors. The level of awareness and under-reporting of sleep apnoea symptoms are poor. The high prevalence of obstructive sleep apnoea symptoms from this study should form the basis for screening hospitalized patients with chronic medical condition across the country.

Impact of Drift on the Vehicle Liftoff Acoustic Environments

NASA Technical Reports Server (NTRS)

Kenny, Jeremy; Giacomoni, Clothilde

2016-01-01

During liftoff a vehicle can drift due to wind, nozzle gimbaling, fly away maneuver, etc... This drift can cause the exhaust plumes to impinge on the deck and cause the noise levels experienced by the vehicle to increase. A small increase in the plume impingement can have a dramatic effect on the noise levels when the vehicle is only a few nozzle diameters from the deck. As the vehicle lifts off the deck the increase in noise levels lessens as the plume impingement increases. Several scale model acoustic tests have been undertaken at Marshall Space Flight Center which had test cases that were used to define the relationship between drift and the noise levels experienced by the vehicle.

Identification of Risk Factors for Nephrotoxicity in Patients Receiving Extended-Duration, High-Trough Vancomycin Therapy

PubMed Central

Contreiras, Claire; Legal, Michael; Lau, Tim T Y; Thalakada, Rosanne; Shalansky, Stephen; Ensom, Mary H H

2014-01-01

Background: In the past, impurities in vancomycin formulations were thought to contribute to nephrotoxicity. In contrast, when current, purer formulations are dosed at conventional trough levels (i.e., 5–15 mg/L), the incidence of nephrotoxicity is relatively low. Recent guidelines have recommended targeting higher vancomycin trough levels in treatment of complicated methicillin-resistant Staphylococcus aureus infections. Dosing based on these higher trough levels may be associated with nephrotoxicity, so the potential risk factors for vancomycin-associated nephrotoxicity require clearer definition. Objectives: To determine the occurrence of nephrotoxicity in patients receiving more than 7 days of vancomycin therapy with high trough levels (15–20 mg/L) and to identify and evaluate specific risk factors related to development of vancomycin-associated nephrotoxicity (i.e., serum creatinine ≥ 44.2 μmol/L or increase ≥ 50% [i.e., ≥ 26.2 μmol/L] from baseline on 2 consecutive days). Methods: Health care records were reviewed for patients seen at 2 major teaching hospitals between January 2008 and March 2011. Patients who had attained high trough levels of vancomycin were screened for eligibility. Patients with unstable renal function, those undergoing hemodialysis, and those for whom dosage and/or sampling times were unclear were excluded. Univariate and multivariate analyses were performed to identify risk factors associated with nephrotoxicity. Univariate variables with p < 0.1 were included in the logistic regression model. Results: Of the 176 patients with high trough levels included in the analysis, 24 (14%) experienced nephrotoxicity. In univariate analysis, admission to a general medicine unit (the setting of care for 16 [67%] of the 24 patients with nephrotoxicity) and extended duration of vancomycin treatment were identified as risk factors for nephrotoxicity (p < 0.1). Other risk factors included gastrointestinal comorbidity (p = 0.056), malignancy (p = 0.044), and febrile neutropenia (p = 0.032). Multivariate analysis identified treatment on general medicine units and treatment courses longer than 7 days as independent predictors of vancomycin-associated nephrotoxicity. Conclusion: Patients being treated on general medicine units and those receiving vancomycin for more than 7 days had an increased likelihood of experiencing nephrotoxicity. The increased risk for patients on general medicine units is likely multifactorial. The relationship between treatment duration and risk of nephrotoxicity appeared to be linear. When using extended-duration, high-trough vancomycin therapy, clinicians should be vigilant in monitoring for nephrotoxicity. PMID:24799722

Collaborative training with a more experienced partner: remediating low pretraining self-efficacy in complex skill acquisition.

2007-12-01

This study examined the effectiveness of collaborative training for individuals with low pretraining self-efficacy versus individuals with high pretraining self-efficacy regarding the acquisition of a complex skill that involved strong cognitive and psychomotor demands. Despite support for collaborative learning from the educational literature and the similarities between collaborative learning and interventions designed to remediate low self-efficacy, no research has addressed how self-efficacy and collaborative learning interact in contexts concerning complex skills and human-machine interactions. One hundred fifty-five young male adults trained either individually or collaboratively with a more experienced partner on a complex computer task that simulated the demands of a dynamic aviation environment. Participants also completed a task-specific measure of self-efficacy before, during, and after training. Collaborative training enhanced skill acquisition significantly more for individuals with low pretraining self-efficacy than for individuals with high pretraining self-efficacy. However, collaborative training did not bring the skill acquisition levels of those persons with low pretraining self-efficacy to the levels found for persons with high pretraining self-efficacy. Moreover, tests of mediation suggested that collaborative training may have enhanced appropriate skill development strategies without actually raising self-efficacy. Although collaborative training can facilitate the skill acquisition process for trainees with low self-efficacy, future research is needed that examines how the negative effects of low pretraining self-efficacy on complex skill acquisition can be more fully remediated. The differential effects of collaborative training as a function of self-efficacy highlight the importance of person analysis and tailoring training to meet differing trainee needs.

Environmental adversity and children's early trajectories of problem behavior: The role of harsh parental discipline.

2017-03-01

This study was performed to examine the role of harsh parental discipline in mediating and moderating the effects of environmental adversity (family socioeconomic disadvantage and adverse life events) on emotional and behavioral problems across early-to-middle childhood. The sample included 16,916 children (48% female; 24% non-White) from the U.K.'s Millennium Cohort Study. We analyzed trajectories of conduct, hyperactivity, and emotional problems, measured at ages 3, 5, and 7 years, using growth curve models. Harsh parental discipline was measured at these ages with parent-reported items on the frequency of using the physical and verbal discipline tactics of smacking, shouting at, and "telling off" the child. As expected, family socioeconomic disadvantage and adverse life events were significantly associated with emotional and behavioral problems. Harsh parental discipline was related to children's trajectories of problems, and it moderated, but did not explain, the effect of environmental risk on these trajectories. High-risk children experiencing harsh parental discipline had the highest levels of conduct problems and hyperactivity across the study period. In addition, harsh parental discipline predicted an increase in emotional symptoms over time in high-risk children, unseen in their counterparts experiencing low levels of harsh parental discipline. However, children in low-risk families were also negatively affected by harsh parental discipline concurrently and over time. In conclusion, harsh parental discipline predicted emotional and behavioral problems in high- and low-risk children and moderated the effects of family poverty and adversity on these problems.

2017-01-01

The purpose of this research was to explore the issue of the psychological aftermaths of traumatic events in women. According to the existing body of evidence, women suffer more often than men from mental health problems as a result of a traumatic event-one of the explanations for this is that women experience sexual trauma more frequently and this type of trauma causes more severe negative consequences. Therefore, the main aim of this research was to compare the aftermaths of sexual and non-sexual traumatic events in women. Only traumatic events in adulthood were taken into consideration and were divided into two categories: recent events (previous two years) and those of an earlier occurrence. Depression and low level of self-esteem were included in the research model as possible consequences of traumatic events. A total of 273 women from Poland took part in a questionnaire survey. As hypothesized, in the case of recent events, participants who experienced a sexual trauma showed a higher level of depression and lower level of self-esteem compared with those subjects, who experienced a non-sexual trauma or did not experience a traumatic event at all. However, this effect was not observed in the case of events of earlier occurrence. Copyright © 2016 John Wiley & Sons, Ltd. Relations between traumatic experiences and the level of depression and self-esteem in women were demonstrated. Women who experienced sexual trauma showed higher levels of depression and lower levels of self-esteem than women who experienced other types of trauma. Time of the occurrence of the traumatic events matters: the relations between traumatic events, depression and self-esteem were demonstrated in the case of the events that occurred within the last two years.

Isoprene emission is an important mechanism for improving the thermotolerance of plant photosystems as temperatures increase. In this study, we measured photosynthesis and isoprene emission in trees along an urban-rural gradient that serves as a proxy for climate change, to understand daily and seasonal responses to changes in temperature and other environmental variables. Leaf-level gas exchange and basal isoprene emission of post oak (Quercus stellata) and sweet gum (Liquidambar styraciflua) were recorded at regular intervals over an entire growing season at urban, suburban, and rural sites in eastern Texas. In addition, the temperature and atmospheric carbon dioxide concentration experienced by leaves were experimentally manipulated in spring, early summer, and late summer. We found that trees experienced lower stomatal conductance and photosynthesis and higher isoprene emission, at the urban and suburban sites compared to the rural site. Path analysis indicated a daily positive effect of isoprene emission on photosynthesis, but unexpectedly, higher isoprene emission from urban trees was not associated with improved photosynthesis as temperatures increased during the growing season. Furthermore, urban trees experienced relatively higher isoprene emission at high CO2 concentrations, while isoprene emission was suppressed at the other sites. These results suggest that isoprene emission may be less beneficial in urban, and potentially future, environmental conditions, particularly if higher temperatures override the suppressive effects of high CO2 on isoprene emission. These are important considerations for modeling future biosphere-atmosphere interactions and for understanding tree physiological responses to climate change. © 2015 John Wiley & Sons Ltd.

High rates of antenatal depression and preterm birth have been reported in Pakistan. Self reported maternal stress and depression have been associated with preterm birth; however findings are inconsistent. Cortisol is a biological marker of stress and depression, and its measurement may assist in understanding the influence of self reported maternal stress and depression on preterm birth. In a prospective cohort study pregnant women between 28 to 30 weeks of gestation from the Aga Khan Hospital for Women and Children completed the A-Z Stress Scale and the Centre for Epidemiology Studies Depression Scale to assess stress and depression respectively, and had a blood cortisol level drawn. Women were followed up after delivery to determine birth outcomes. Correlation coefficients and Wilcoxon rank sum test was used to assess relationship between preterm birth, stress, depression and cortisol. Logistic regression analysis was used to determine the key factors predictive of preterm birth. 132 pregnant women participated of whom 125 pregnant women had both questionnaire and cortisol level data and an additional seven had questionnaire data only. Almost 20% of pregnant women (19·7%, 95% CI 13·3-27·5) experienced a high level of stress and nearly twice as many (40·9%, 95% CI 32·4-49·8%) experienced depressive symptoms. The median of cortisol level was 27·40 ug/dl (IQR 22·5-34·2). The preterm birth rate was 11·4% (95% CI 6·5-18). There was no relationship between cortisol values and stress scale or depression. There was a significant positive relationship between maternal depression and stress. Preterm birth was associated with higher parity, past delivery of a male infant, and higher levels of paternal education. Insufficient numbers of preterm births were available to warrant the development of a multivariable logistic regression model. Preterm birth was associated with higher parity, past delivery of a male infant, and higher levels of paternal education. There was no relationship between stress, and depression, cortisol and preterm birth. There were high rates of stress and depression among this sample suggesting that there are missed opportunities to address mental health needs in the prenatal period. Improved methods of measurement are required to better understand the psychobiological basis of preterm birth.

Burnout, Perceived Stress, and Job Satisfaction Among Trauma Nurses at a Level I Safety-Net Trauma Center.

PubMed

Munnangi, Swapna; Dupiton, Lynore; Boutin, Anthony; Angus, L D George

Nurses are at the forefront of our health care delivery system and have been reported to exhibit a high level of burnout. Burnout and stress in trauma nurses at a safety-net hospital can negatively impact patient care. Safety-net hospitals are confronted with unique social, financial, as well as resource problems that can potentially make the work environment frustrating. The purpose of this study was to explore the levels of burnout, stress, and job satisfaction in nurses providing care to trauma patients at a Level I safety-net trauma center. A cross-sectional survey design was used to investigate principal factors including personal and professional demographics, burnout, perceived stress, and job satisfaction. Trauma nurses working at a Level I safety-net trauma center are stressed and exhibited moderate degree of burnout. The extent of emotional exhaustion experienced by the nurses varied with work location and was highest in surgical intensive care unit nurses. The level of job satisfaction in terms of opportunities for promotion differed significantly by race and the health status of the nurses. Satisfaction with coworkers was lowest in those nurses between the ages of 60-69 years. Female nurses were more satisfied with their coworkers than male nurses. In addition, the study revealed that significant relationships exist among perceived stress, burnout, and job satisfaction. Work environment significantly impacts burnout, job satisfaction, and perceived stress experienced by trauma nurses in a safety-net hospital. Nursing administration can make an effort to understand the levels of burnout and strategically improve work environment for trauma nurses in order to minimize stressors leading to attrition and enhance job satisfaction.

This paper describes findings from a study that evaluated the implementation and impact of case management for long-term conditions (CMLTC) in 10 primary care trusts (PCTs). Patients who have long-term conditions and complex health and social needs may require case management to deliver and coordinate their care from a range of agencies. A cross-sectional postal survey of managers with lead responsibility for CMLTC in each PCT is adopted to describe the implementation of services. A retrospective cohort analysis of longitudinal routinely collected admission data for patients enrolled within the CMLTC service (nine months before and nine months after the entry; n = 867) is used to measure their impact. The organisation of case management varied between PCTs in some aspects despite a high level of coordination across the geographical area. Mean emergency admissions and associated length of stay (LOS) for patients reduced significantly in the nine months after the service entry. There were a number of fairly robust positive and negative influences on these outcome measures in the regression analysis. Most patients with a history of emergency admissions experienced a marked improvement over time. However, most of those without any or with few admissions experienced an increase in admissions and corresponding LOS. Furthermore, a proportion of frequent service users with particular diagnoses also experienced an increase or remained at a high level. A very modest effect was shown with regard to the features of case management arrangements. For each day spent in hospital before service entry, patients are predicted to experience a reduction of nearly one day after. The main contributor explaining increases in LOS for emergency admissions was the number of primary and secondary diagnoses. Each added diagnosis is associated with a 2.4-day increase in LOS, everything else being equal.

Roman High- (RHA) and Low-Avoidance (RLA) outbred rats, which differ for a respectively rapid vs. poor acquisition of the active avoidance response in the shuttle-box, display differences in sexual activity when put in the presence of a sexually receptive female rat. Indeed RHA rats show higher levels of sexual motivation and copulatory performance than RLA rats, which persist also after repeated sexual activity. These differences have been correlated to a higher tone of the mesolimbic dopaminergic system of RHA rats vs. RLA rats, revealed by the higher increase of dopamine found in the dialysate obtained from the nucleus accumbens of RHA than RLA rats during sexual activity. This work shows that extracellular dopamine and noradrenaline (NA) also, increase in the dialysate from the medial prefrontal cortex (mPFC) of male RHA and RLA rats put in the presence of an inaccessible female rat and more markedly during direct sexual interaction. Such increases in dopamine (and its main metabolite 3,4-dihydroxyphenylacetic acid, DOPAC) and NA were found in both sexually naïve and experienced animals, but they were higher: (i) in RHA than in RLA rats; and (ii) in sexually experienced RHA and RLA rats than in their naïve counterparts. Finally, the differences in dopamine and NA in the mPFC occurred concomitantly to those in sexual activity, as RHA rats displayed higher levels of sexual motivation and copulatory performance than RLA rats in both the sexually naïve and experienced conditions. These results suggest that a higher dopaminergic tone also occurs in the mPFC, together with an increased noradrenergic tone, which may be involved in the different copulatory patterns found in RHA and RLA rats, as suggested for the mesolimbic dopaminergic system.

The aim of this research is to investigate the degree of distress experienced by nurses in response to the challenging behaviour of nursing home residents (residents' challenging behaviour) and their impact on nurses individual resources (general health, burnout and work ability). Because of the increasing and ageing population of nursing home residents, professional nursing care faces several challenges. One highly prevalent issue among nursing home residents is the so-called 'challenging behaviour'. However, to date, 'challenging behaviour' has not yet been recognised as an occupational stressor, and the extent of the impact of 'challenging behaviour' on nurses' well-being and functioning is not well understood. Cross-sectional study. Self-report questionnaire data collected from 731 registered nurses and nursing aides in 56 German nursing homes were used in a secondary data analysis. The level of residents' challenging behaviour-related distress that nurses experienced was assessed using a scale consisting of nine questions. Validated instruments were used for the assessment of individual resources. The mean score for residents' challenging behaviour-related distress was 41·3 (SD 21·2). Twenty-seven per cent of all nurses reported over 50 residents' challenging behaviour. Residents' challenging behaviour had a significant impact on all three measures of individual resources. Specifically, nurses exposed to frequent residents' challenging behaviour reported a significantly lower quality of general health, reduced workability and high burnout levels. Our findings indicate that residents' challenging behaviour-related distress is a significant work place stressor for nurses in nursing homes with a clear impact on general health, the risk of burnout and work ability. Our findings suggest that residents' challenging behaviour is a stressor for nurses in nursing homes. Further scientific and practical attention is necessary from the point of view of working conditions for nurses. The development of preventive concepts for nursing staff and residents is recommended. © 2012 Blackwell Publishing Ltd.

Purpose: To report the toxicity and preliminary clinical outcomes of a prospective trial evaluating 19-Gy, single-fraction high-dose-rate (HDR) brachytherapy for men with low- and intermediate-risk prostate cancer. Methods and Materials: A total of 63 patients were treated according to an institutional review board-approved prospective study of single-fraction HDR brachytherapy. Eligible patients had tumor stage ≤T2a, prostate-specific antigen level ≤15 ng/mL, and Gleason score ≤7. Patients with a prostate gland volume >50 cm{sup 3} and baseline American Urologic Association symptom score >12 were ineligible. Patients underwent transrectal ultrasound-guided transperineal implantation of the prostate, followed by single-fraction HDR brachytherapy. Treatment was delivered using {sup 192}Irmore » to a dose of 19 Gy prescribed to the prostate, with no additional margin applied. Results: Of the 63 patients, 58 had data available for analysis. Five patients had withdrawn consent during the follow-up period. The median follow-up period was 2.9 years (range 0.3-5.2). The median age was 61.4 years. The median gland volume at treatment was 34.8 cm{sup 3}. Of the 58 patients, 91% had T1 disease, 71% had Gleason score ≤6 (29% with Gleason score 7), and the median pretreatment prostate-specific antigen level was 5.1 ng/mL. The acute and chronic grade 2 genitourinary toxicity incidence was 12.1% and 10.3%, respectively. No grade 3 urinary toxicity occurred. No patients experienced acute rectal toxicity grade ≥2, and 2 experienced grade ≥2 chronic gastrointestinal toxicity. Three patients experienced biochemical failure, yielding a 3-year cumulative incidence estimate of 6.8%. Conclusions: Single-fraction HDR brachytherapy is well-tolerated, with favorable preliminary biochemical and clinical disease control rates.« less

Resilience to bullying victimization: the role of individual, family and peer characteristics.

PubMed

Sapouna, Maria; Wolke, Dieter

2013-11-01

Little research attention has been paid to bullied students who function better than expected and are therefore defined as "resilient". The present longitudinal study aimed to identify individual, family and peer factors that predict fewer than expected levels of depression and delinquency following experiences of bullying victimization. The sample consisted 3,136 adolescents. Self-report data were used to measure bullying victimization at age 13 and 14 and depression and delinquency at age 14. We examined the effects of gender, self-esteem, social alienation, parental conflict, sibling victimization and number of close friends on levels of emotional and behavioral resilience following bullying victimization. The resilience measures were derived by regressing depression and delinquency scores at age 14 on levels of bullying victimization at age 13 and 14, respectively. The adolescents who reported low depression despite frequently experiencing bullying tended to be male, had higher self-esteem, were feeling less socially alienated, were experiencing low levels of conflict with parents and were not victimized by siblings. On the other hand, the adolescents who reported low delinquency despite frequently experiencing bullying tended to be female, had higher self-esteem, were experiencing low levels of conflict with parents, were not victimized by siblings and had less close friends. Relationships with parents and siblings continue to play some role in promoting emotional and behavioral adjustment among victims of bullying and, therefore, interventions are more likely to be successful if they target both the psychosocial skills of adolescents and their relationships with their family.

The Cycle of Violence: Examining Attitudes Toward and Experiences of Corporal Punishment in a Representative German Sample.

The use of corporal punishment (CP) is controversial despite the negative consequences of its use that have been documented. Consequences include the use of CP by those who experienced CP themselves, described in the theory of the cycle of violence. There are little data on the cycle of violence, especially on those who break it and in representative samples. This study examines the cycle of violence in a representative sample by analyzing experiences of and attitudes toward CP. Attitudes toward, and own experiences of, CP by their parents were assessed in a sample of 2,519 individuals (female 54.6%, age range = 14-99 years, M = 48.9 years). Latent class analysis (LCA) was used to identify subgroups of participants who support and oppose CP. Breaking the cycle, defined as having experienced CP and opposing CP, was examined. Factors associated with positive and negative attitudes toward CP were identified using group comparisons and binary logistic regression. The majority of the sample opposed CP (56%), whereas one third supported less severe forms of CP and 8.2% also supported severe CP. Those supporting CP reported having experienced CP by their parents more often. Of those who had experienced CP, 47% were identified as breaking the cycle. Female gender, younger age, not being divorced, and being married and living together, as well as a higher level of education were associated with breaking the cycle. Even though CP was legally banned in Germany, a relatively high proportion still reports positive attitudes toward and experiences of CP. The ban of CP by the federal government seems to be an effective measure to change attitudes on a societal level as rates were lower in comparison with earlier studies. Future studies should examine interactions between different types of CP, attitudes toward its use, and additional mediating factors.

Intimate partner violence (IPV) often includes economic abuse as one tactic commonly used by an abuser; unfortunately, there is a lack of empirical understanding of economic abuse. Additionally, research is limited on the predictors of economic self-sufficiency in the lives of women experiencing IPV. This paper furthers our knowledge about economic abuse and its relationship with economic self-sufficiency by presenting the results from an exploratory study with IPV survivors participating in a financial literacy program. Of the 120 individuals who participated in the first wave, 94% experienced some form of economic abuse, which also correlated highly with other forms of IPV. Seventy-nine percent experienced some form of economic control, 79% experienced economic exploitative behaviors, and 78% experienced employment sabotage. MANOVA results also indicated that economic control differed significantly based on education with those with a high school education experiencing higher rates than those with less than high school education or those with some college. Finally, results from the OLS regressions indicated that experiencing any form of economic abuse as well as economic control significantly predicted a decrease in economic self sufficiency. Implications suggest that advocates should assess for economic abuse when working with survivors and should be prepared to offer financial tools to increase survivors' economic self-sufficiency. Policymakers should understand the ramifications of economic abuse and create policies that support survivors and prohibit economic abuse. Finally, more research is needed to fully understand economic abuse and its impact on survivors and their economic self-sufficiency.

Nursing students may exhibit the characteristics of resistance to stress, such as hardiness, which can reduce the risk of burnout. However, we found only one published study about these phenomena among nursing students. Thus, we investigated the association between hardiness and burnout in such students. An analytic, cross-sectional study was conducted among 570 nursing students from three Brazilian universities. Data were collected relating to sociodemographic characteristics, hardiness, and burnout, which we analyzed using inferential statistics. We observed that 64.04% of nursing students in the sample had a high level of emotional exhaustion, 35.79% had a high level of cynicism, and 87.72% had a low level of professional efficacy: these are dimensions of burnout. We also found that 48.77% had a high level of control, 61.40% a high level of commitment, and 35.44% a high level of challenge: these are dimensions of hardiness. Only 24.74% of the students experienced burnout, and 21.93% met the criteria for a hardy personality. There was a statistically significant difference between the frequency of hardiness and burnout (p = 0.033), with 68.00% of hardy students not exhibiting burnout. Although nursing students live with educational stressors, burnout was not preponderant in our sample students; this may be linked to hardiness. Thus, given its benefits to student life and health, we recommend the development of strategies to promote hardiness among nursing students.

The study objective was to determine the quantitative electroencephalographic correlates of meditation, as well as the effects of hindering (15 Hz) and facilitative (7 Hz) binaural beats on the meditative process. The study was a mixed design, with experience of the subject as the primary between-subject measure and power of the six classic frequency bands (δ, θ, low α, high α, β, γ), neocortical lobe (frontal, temporal, parietal, occipital), hemisphere (left, right), and condition (meditation only, meditation with 7-Hz beats, meditation with 15-Hz beats) as the within-subject measures. The study was conducted at Laurentian University in Sudbury, Ontario, Canada. The subjects comprised novice (mean of 8 months experience) and experienced (mean of 18 years experience) meditators recruited from local meditation groups. Experimental manipulation included application of hindering and facilitative binaural beats to the meditative process. Experienced meditators displayed increased left temporal lobe δ power when the facilitative binaural beats were applied, whereas the effect was not observed for the novice subjects in this condition. When the hindering binaural beats were introduced, the novice subjects consistently displayed more γ power than the experienced subjects over the course of their meditation, relative to baseline. Based on the results of this study, novice meditators were not able to maintain certain levels of θ power in the occipital regions when hindering binaural beats were presented, whereas when the facilitative binaural beats were presented, the experienced meditators displayed increased θ power in the left temporal lobe. These results suggest that the experienced meditators have developed techniques over the course of their meditation practice to counter hindering environmental stimuli, whereas the novice meditators have not yet developed those techniques.

2014-04-01

This study examined relationships between cumulative trauma (CT) and urban African American (AA) adolescents' blood pressure (BP), heart rate (HR), and perceptions of health. A correlational design using secondary data analysis studied effects of CT, health outcomes, and perceptions of health. Participants were 175 urban AA youth (11-16 years) who completed structured surveys and physiological measures of HR and BP before and after exercise. AA youth were experiencing high levels of CT. Negative correlations were obtained between AA females' perceptions of their health and systolic BP with levels of trauma. No gender differences were found in HR or BP. AA females with high CT may perceive themselves as less healthy and can be at risk for health problems. © 2014, Wiley Periodicals, Inc.

Natural Mentoring Processes Deter Externalizing Problems Among Rural African American Emerging Adults: A Prospective Analysis

2011-01-01

A 3-wave model linking natural mentoring relationships to externalizing behavior was tested with 345 rural African American emerging adults in their final year of high school. Structural equation models were executed linking multi-informant reports of mentor-emerging adult relationship quality with youths’ externalizing behavior 18 months later. Consistent with our primary hypotheses, emerging adults whose relationships with their natural mentors were characterized by instrumental and emotional support and affectively positive interactions reported lower levels of anger, rule-breaking behavior, and aggression. These effects emerged independent of the influences of family support and youth gender. Two intrapersonal processes, a future orientation and self-regulation, emerged as mediators of the influence of natural mentoring relationships. The influence of natural mentors was most pronounced for emerging adults experiencing high levels of life stress. PMID:21293917

Abstract Purpose: Studies on drug use in transgender populations, particularly those in resource-limited settings, are scarce. Considering that drug use can be a coping mechanism to deal with stigma and traumatic experiences, we examined associations between stigma, trauma, and drug use in a national sample of transgender women from the Dominican Republic. Methods: Bivariate analyses examined differences between drug users and abstainers (n=287). Multivariate analyses reported odds ratios (OR) with general drug, marijuana, and cocaine use as outcomes (n=243). Results: A quarter of respondents (24.5%) experienced sexual abuse, 12.1% were tortured, and 20.1% experienced a murder attempt. More than a quarter reported using illegal drugs (26.1%). Drug users had lower socioeconomic status; 30.0% of drug users had a primary level of education or less (18.2% of abstainers) and 17.6% of drug users had higher income, defined as greater than 10,001 pesos (∼$210 United States Dollars, USD) per month (28.1% of abstainers). More than half of drug users experienced some form of trauma (51.4%) compared to 43.5% of abstainers, and 28.4% of drug users, compared to 17.1% of abstainers, experienced a murder attempt on her life. Independent sample t-tests found significant differences between drug users and abstainers. Transgender women who experienced sexual abuse had three times high odds of using cocaine. Drug users were more likely to have experienced sexual abuse and attempted suicide (p<0.05 for both). Respondents who attempted suicide had higher odds of using drugs generally and using marijuana specifically, compared to respondents who had not attempted suicide (OR=2.665 and 3.168, respectively). Higher scores on the stigma scale were associated with higher odds of any drug use and cocaine use (OR=1.132 and 1.325, respectively). Conclusions: Although some nations have implemented antidiscrimination policies protecting transgender citizens, these policies are not consistently enforced. Eliminating stigma and stigmatizing policies may reduce rates of drug use as a coping mechanism. PMID:29142909

Gonadotropin level abnormalities in women with cyclic mastalgia.

Women with cyclic mastalgia seem to be at risk of fibrocystic breast disease and/or breast cancer. We studied the relationships between mastalgia and hormone levels throughout the menstrual cycle. Ostensibly healthy women were monitored during a sum of 326 cycles. A case-control study compared personal and hormonal variables of 30 women experiencing cyclic mastalgia with those of 77 women without this symptom. Except sleeping times, no significant differences were found in personal variables. Cyclic mastalgia and symptoms of fluid retention were slightly associated. Menses and the luteal phase were significantly longer in cases than in controls. Gonadotropin but not ovarian hormone levels were also significantly higher in cases throughout the cycle. Cyclic mastalgia is less related to symptoms of fluid retention or to ovarian hormone levels than to regularly high gonadotropin levels, specific inhibitors might thus be used to alleviate the symptom.

Extraction of Children's Friendship Relation from Activity Level

Children learn to fit into society through living in a group, and it's greatly influenced by their friend relations. Although preschool teachers need to observe them to assist in the growth of children's social progress and support the development each child's personality, only experienced teachers can watch over children while providing high-quality guidance. To resolve the problem, this paper proposes a mathematical and objective method that assists teachers with observation. It uses numerical data of activity level recorded by pedometers, and we make tree diagram called dendrogram based on hierarchical clustering with recorded activity level. Also, we calculate children's ``breadth'' and ``depth'' of friend relations by using more than one dendrogram. When we record children's activity level in a certain kindergarten for two months and evaluated the proposed method, the results usually coincide with remarks of teachers about the children.

Viana, Andres G; Gratz, Kim L; Bierman, Karen L

2013-01-01

Temperamental vulnerabilities (e.g., behavioral inhibition, anxiety sensitivity) and cognitive biases (e.g., interpretive and judgment biases) may exacerbate feelings of stress and anxiety, particularly among late adolescents during the early years of college. The goal of the present study was to apply person-centered analyses to explore possible heterogeneity in the patterns of these four risk factors in late adolescence, and to examine associations with several anxiety outcomes (i.e., worry, anxiety symptoms, and trait anxiety). Cluster analyses in a college sample of 855 late adolescents revealed a Low-Risk group, along with four reliable clusters with distinct profiles of risk factors and anxiety outcomes (Inhibited, Sensitive, Cognitively-Biased, and Multi-Risk). Of the risk profiles, Multi-Risk youth experienced the highest levels of anxiety outcomes, whereas Inhibited youth experienced the lowest levels of anxiety outcomes. Sensitive and Cognitively-Biased youth experienced comparable levels of anxiety-related outcomes, despite different constellations of risk factors. Implications for interventions and future research are discussed.

To examine whether flow (Csikszentmihalyi (1990). Flow: The psychology of optimal experience. NY: Harper & Row) and dissociation (Jacobs (1986). Journal of Gambling Behavior, 2, 15-31) are experienced across sports and recreational and pathological gambling, we assessed a sample of 511 college students (256 females and 255 males, M age = 19.54) that was comprised of 14 pathological gamblers, 21 non-addicted gamblers, and 476 athletes. The findings showed that both flow and dissociation lay on a continuum of subjective experiences across activity groups. Specifically, pathological gamblers experienced lower levels of flow than athletes, whereas recreational gamblers lay in between the previous groups in this regard. In contrast, pathological gamblers experienced higher mean levels of dissociation than athletes and recreational gamblers who, in turn, were similar in this regard. A LISREL model showed that flow was positively associated with general emotional well-being, whereas dissociation was negatively associated with well-being.

Household instability and self-regulation among poor children.

PubMed

McCoy, Dana Charles; Raver, C Cybele

Past research suggests that poverty may negatively influence children's psychological and behavioral health by increasing their exposure to chaotic living conditions in the household. The present study provides a descriptive 'snapshot' of instability in low-income households, and examines the associations between exposure to major destabilizing events over the course of a year and three domains of poor urban children's self-regulation. Descriptive analyses suggest that although caregivers from unstable households report higher average levels of health problems and depression, they also have greater assets/savings, are more educated, and are less likely to be immigrants than caregivers from stable households. Results of propensity score-matched regression analyses reveal that high levels of household instability are significantly and negatively associated with preschoolers' effortful control and global attention/impulsivity control, but not with their executive function. Children from mildly unstable homes (i.e., those who had experienced a single destabilizing event in the past year) showed no significant differences in any domain of self-regulation relative to their peers from stable households, suggesting a dose-response relationship between the number of destabilizing events experienced by children and their outcomes. Implications for theories of poverty-related adversity, stress, and parenting are discussed in addition to future directions for research.

Exploring the Link Between Alcohol and Marijuana Use and Teen Dating Violence Victimization Among High School Students: The Influence of School Context.

Adolescence is a developmental period when dating behavior is first initiated and when the risk of abuse by or against a dating partner begins to emerge. It is also one in which experimentation with alcohol and illicit substances typically begins. The current study examined the association between recent alcohol use and recent marijuana use and the experience of physical and verbal teen dating violence (TDV) victimization while considering the potential influence of school contextual variables. Data came from 27,758 high school students attending 58 Maryland public high schools. Hierarchical linear modeling was used to identify student- and school-level predictors associated with TDV. Results indicated that approximately 11% of students reported experiencing physical TDV and 11% of students reported experiencing verbal TDV over the past year. In addition, 33% of students reported recent alcohol use and 21% reported recent marijuana use. Hierarchical linear modeling results revealed that students who reported frequent recent alcohol or recent marijuana use were at increased odds of experiencing physical (adjusted odds ratio [AOR]alcohol = 2.80, p < .001; AORmarijuana = 2.03, p < .001) or verbal TDV (AORalcohol = 2.63, p < .001; AORmarijuana = 2.20, p < .001) victimization compared to students who reported little or no alcohol or marijuana use. School support was a protective factor for both physical TDV (AOR = 0.74, p < .001) and verbal TDV (AOR = 0.76, p < .001) victimization. Findings suggested that prevention efforts to address alcohol and marijuana use may have an effect on TDV victimization. Results also highlight the potential utility of enhancing student perceptions of school support as an approach for reducing TDV victimization. © 2015 Society for Public Health Education.

We examined the psychological impact of the 2003 outbreak of severe acute respiratory syndrome (SARS) on hospital employees in Beijing, China. In 2006, randomly selected employees (n = 549) of a hospital in Beijing were surveyed concerning their exposure to the 2003 SARS outbreak, and the ways in which the outbreak had affected their mental health. About 10% of the respondents had experienced high levels of posttraumatic stress (PTS) symptoms since the SARS outbreak. Respondents who had been quarantined, or worked in high-risk locations such as SARS wards, or had friends or close relatives who contracted SARS, were 2 to 3 times more likely to have high PTS symptom levels, than those without these exposures. Respondents' perceptions of SARS-related risks were significantly positively associated with PTS symptom levels and partially mediated the effects of exposure. Altruistic acceptance of work-related risks was negatively related to PTS levels. The psychological impact of stressful events related to an infectious disease outbreak may be mediated by peoples' perceptions of those events; altruism may help to protect some health care workers against these negative impacts.

The 2015 National Health and Morbidity Survey estimated that over 29% of the adult population of Malaysia suffers from mental distress, a nearly 3-fold increase from the 10.7% estimated by the NHMS in 1996 pointing to the potential beginnings of a public health crisis. This study aimed to better understand this trend by assessing depressive symptoms and their correlates in a cross-section of Malaysians. Specifically, it assesses stress, perceived locus of control, and various socio-demographic variables as possible predictors of depressive symptoms in the Malaysian context. A total of 728 adults from three Malaysian states (Selangor, Penang, Terengganu) completed Beck’s depression inventory as well as several other measures: 10% of respondents reported experiencing severe levels of depressive symptoms, 11% reported moderate and 15% reported mild depressive symptoms indicating that Malaysians are experiencing high levels of emotional distress. When controlling for the influence of other variables, depressive symptoms were predictably related to higher levels of stress and lower levels of internal locus of control. Ethnic Chinese Malaysians, housewives and those engaged in professional-type occupations reported less depressive symptoms. Business owners reported more depressive symptoms. Further research should look more into Malaysians’ subjective experience of stress and depression as well as explore environmental factors that may be contributing to mental health issues. It is argued that future policies can be designed to better balance individual mental health needs with economic growth. PMID:28878710
