Terms modified by Stressful Selected AbstractsStressful but rewarding: Norwegian personnel mobilised for the 2004 tsunami disasterDISASTERS, Issue 3 2009Siri Thoresen Adequate responses to disasters and emergency situations rely, among other factors, on coping abilities in disaster workers and emergency personnel. In this study, different aspects of disaster-related stressors and training/experience were investigated in Norwegian personnel (n = 581) mobilised for the 2004 tsunami disaster. The level of stress reactions, measured nine to ten months after the tsunami, was relatively low in this sample, indicating that the personnel coped well with the challenges of the disaster. The level of intrusive memories was higher in disaster-area personnel (n = 335) than in home-base personnel (n = 246). Stress reactions were significantly associated with witnessing experiences (disaster-area group) and with having to reject victims in need of help (both groups). Specific preparation for the mission was associated with a lower level of stress reactions in disaster-area personnel. Such factors may be considered in training and preparation programmes for disaster workers.

Robertson Abstract: Stressful and positive family caregiving experiences were examined as predictors of caregivers' patterns of positive and negative affect in a sample of families providing care for a relative with dementia (N= 234). Four affect pattern groups were identified: (a) Well Adjusted (i.e., high positive affect, low negative affect); (b) Ambiguous (i.e., low on both positive and negative affect); (c) Intense (i.e., high on both positive and negative affect); and (d) Distressed (i.e., high negative affect, low positive affect). A multivariate model that included demographic characteristics and indicators of stressful and positive experiences of caregiving yielded 2 significant discriminant functions that served to classify caregivers correctly into their known affect groups. Implications for improving intervention efforts targeting family caregivers are discussed. [source] The sleep of co-sleeping infants when they are not co-sleeping: Evidence that co-sleeping is stressfulDEVELOPMENTAL PSYCHOBIOLOGY, Issue 1 2002Melissa Hunsley Abstract Co-sleeping proponents consider the practice to be "natural" and a potential protection against sudden infant death syndrome (SIDS); others consider the practice of an infant sleeping in the parents' bed for prolonged periods at night to place an infant at risk for harm or death. For this study, co-sleeping was investigated from a different perspective, that is, as a significant early experience to investigate as it may have implications for the infant's development. The sleep of 101 normal, full-term infants was recorded nonintrusively in the home for 24 hr periods when they were 5 weeks and 6 months old. Infants were assigned to three groups: short-term co-sleepers, long-term co-sleepers, and non-co-sleepers. Their sleep states and wakefulness were compared at the two ages and over age. At 5 weeks and 6 months, the long-term co-sleeping infants differed significantly from the non-co-sleepers on a number of measures: At 5 weeks, they showed more quiet sleep and longer bouts of quiet sleep; and at 6 months, they also showed less active sleep, fewer arousals in active sleep, and less wakefulness. Each of these differences indicates a markedly lower arousal level in the long-term co-sleeping infants. This sleep pattern has been repeatedly found to be an indicator of stress. We infer that a major source of stress for these infants is the experience of sleep disturbance documented for infants when they were co-sleeping. Based on extensive evidence for long-term effects of early stress, we conclude that co-sleeping should have significant implications for infants' neurobehavioral development. © 2002 John Wiley & Sons, Inc.

Parker Objective: Examinations are anecdotally viewed as extremely stressful to Singapore schoolchildren. We test this postulate by obtaining parental ratings of children's emotional stress levels longitudinally in a large representative sample of sixth (P6) and fifth (P5) class primary schoolchildren, respectively, exposed and unexposed to a streaming examination. Method: Children's stress levels were rated monthly by a parent for 10 months. Results: Analyses failed to find evidence of any differential stress impact across P6 and P5 comparison groups, apart from a subset of P6 children whose parents complied with every monthly survey. Conclusion: The streaming examination in the final year of primary school did not emerge as a general stressor to children, but achieved salience within a defined subset of children whose parents were highly study compliant. Study compliance may be a proxy variable of some import, and have wider relevance to other cohort studies and to intervention trials. [source] Commercial aviation in-flight emergencies and the physicianEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2007Robert Cocks Abstract Commercial aviation in-flight emergencies are relatively common, so it is likely that a doctor travelling frequently by air will receive a call for help at some stage in their career. These events are stressful, even for experienced physicians. The present paper reviews what is known about the incidence and types of in-flight emergencies that are likely to be encountered, the international regulations governing medical kits and drugs, and the liability, fitness and indemnity issues facing ,Good Samaritan' medical volunteers. The medical and aviation literature was searched, and information was collated from airlines and other sources regarding medical equipment available on board commercial aircraft. Figures for the incidence of significant in-flight emergencies are approximately 1 per 10,40 000 passengers, with one death occurring per 3,5 million passengers. Medically related diversion of an aircraft following an in-flight emergency may occur in up to 7,13% of cases, but passenger prescreening, online medical advice and on-board medical assistance from volunteers reduce this rate. Medical volunteers may find assisting with an in-flight emergency stressful, but should acknowledge that they play a vital role in successful outcomes. The medico-legal liability risk is extremely small, and various laws and industry indemnity practices offer additional protection to the volunteer. In addition, cabin crew receive training in a number of emergency skills, including automated defibrillation, and are one of several sources of help available to the medical volunteer, who is not expected to work alone. [source] Previous experience of withdrawal from chronic diazepam ameliorates the aversiveness of precipitated withdrawal and reduces withdrawal-induced c-fos expression in nucleus accumbensEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 4 2000Sarah J. Dunworth Abstract Flumazenil (20 mg/kg, i.p.)-precipitated withdrawal from chronic treatment with diazepam (DZP, 15 mg/kg, s.c. in sesame oil for 21 days) resulted in a decreased seizure threshold to the convulsant, pentylenetetrazole (PTZ), infused into the tail vein; withdrawal from 21-day chronic diazepam treatment, interspersed with two periods of drug withdrawal, resulted in a greater decrease in convulsant threshold. A separate experiment showed that consumption of a sucrose solution immediately prior to precipitated withdrawal resulted in a decreased subsequent consumption of the sucrose solution; no such evidence of a conditioned taste aversion (CTA) was seen in mice given prior experience of withdrawal. Thus, prior experience of withdrawal enhanced the effects of a subsequent precipitated withdrawal in increasing seizure sensitivity, but weakened the ability of this withdrawal to serve as an aversive unconditioned stimulus (US). The weakening of the aversive properties of precipitated withdrawal may reflect habituation to the withdrawal stimulus, and was accompanied by a loss of the ability of withdrawal to induce c-fos expression in the shell of the nucleus accumbens, an area sensitive to both novel, and stressful, as well as rewarding stimuli. [source] THE CONTRIBUTION OF SPONTANEOUS MUTATION TO VARIATION IN ENVIRONMENTAL RESPONSES OF ARABIDOPSIS THALIANA: RESPONSES TO LIGHTEVOLUTION, Issue 2 2005Christina M. Kavanaugh Abstract It has been hypothesized that new, spontaneous mutations tend to reduce fitness more severely in more stressful environments. To address this hypothesis, we grew plants representing 20 Arabidopsis thaliana mutationaccumulation (M-A) lines, advanced to generation 17, and their progenitor, in differing light conditions. The experiment was conducted in a greenhouse, and two treatments were used: full sun and shade, in which influx of red light was reduced relative to far-red. The shade treatment was considered the more stressful because mean absolute fitness was lower in that treatment, though not significantly so. Plants from generation 17 of M-A developed significantly faster than those from generation 0 in both treatments. A significant interaction between generation and treatment revealed that, counter to the hypothesis, M-A lines tended to have higher fitness on average relative to the progenitor in the shaded conditions, whereas, in full sun, the two generations were similar in fitness. A secondary objective of this experiment was to characterize the contribution of new mutations to genotype x environment interaction. We did not, however, detect a significant interaction between M-A line and treatment. Plots of the line-specific enviromental responses indicate no tendency of new mutations to contribute to fitness trade-offs between environments. They also do not support a model of conditionally deleterious mutation, in which a mutatn reduces fitness only in a particular environment. These results suggest that interactions between genotype and light environment previously documented for A. thaliana are not explicable primarily as a consequence of steady input of spontaneous mutations having environment-specific effects.

[source] Metamorphosis offsets the link between larval stress, adult asymmetry and individual qualityFUNCTIONAL ECOLOGY, Issue 2 2008M. Campero Summary 1It is poorly understood which traits translate larval stressors into adult fitness in animals where larval and adult stages are separated by metamorphosis. Although fluctuating asymmetry (FA) is often assumed to do so, especially in insects the relationship between larval stress, adult FA and individual quality is often absent. One suggested hypothesis for this is the higher mortality of low quality (hence more asymmetric) animals during metamorphosis (i.e. developmental selection hypothesis). 2Here we test this hypothesis and also propose and test an alternative hypothesis where metamorphosis is stressful but not lethal and increases FA of all animals up to a certain level (i.e. stressful metamorphosis hypothesis). 3We manipulated larval stress (food stress and pesticide stress) and measured FA before and after metamorphosis in the damselfly Coenagrion puella. Additionally, we assessed the relationship between FA and individual quality variables measured at metamorphosis (age, mass and two immune variables: phenoloxidase (PO) and haemocyte number). 4Before metamorphosis, FA reflected the combination of food and pesticide stress and was negatively related with mass and both immune variables after metamorphosis. These patterns were, however, offset after metamorphosis. Low mortality, not linked to FA during metamorphosis, indicates that developmental selection cannot explain this. Instead, the strong increase in FA up to equal levels across treatments during metamorphosis supports the stressful metamorphosis hypothesis. 5Taken together, the developmental stage in which FA is measured may critically determine the reliability of FA as an indicator of stress and of individual quality in insects. [source] Performance of High Arctic tundra plants improved during but deteriorated after exposure to a simulated extreme temperature eventGLOBAL CHANGE BIOLOGY, Issue 12 2005Fleur L. Marchand Abstract Arctic ecosystems are known to be extremely vulnerable to climate change. As the Intergovernmental Panel on Climate Change scenarios project extreme climate events to increase in frequency and severity, we exposed High Arctic tundra plots during 8 days in summer to a temperature rise of approximately 9°C, induced by infrared irradiation, followed by a recovery period. Increased plant growth rates during the heat wave, increased green cover at the end of the heat wave and higher chlorophyll concentrations of all four predominating species (Salix arctica Pall., Arctagrostis latifolia Griseb., Carex bigelowii Torr. ex Schwein and Polygonum viviparum L.) after the recovery period, indicated stimulation of vegetative growth. Improved plant performance during the heat wave was confirmed at plant level by higher leaf photochemical efficiency (Fv/Fm) and at ecosystem level by increased gross canopy photosynthesis. However, in the aftermath of the temperature extreme, the heated plants were more stressed than the unheated plants, probably because they acclimated to warmer conditions and experienced the return to (low) ambient as stressful. We also calculated the impact of the heat wave on the carbon balance of this tundra ecosystem. Below- and aboveground respiration were stimulated by the instantaneous warmer soil and canopy, respectively, outweighing the increased gross photosynthesis. As a result, during the heat wave, the heated plots were a smaller sink compared with their unheated counterparts, whereas afterwards the balance was not affected. If other High Arctic tundra ecosystems react similarly, more frequent extreme temperature events in a future climate may shift this biome towards a source. It is uncertain, however, whether these short-term effects will hold when C exchange rates acclimate to higher average temperatures. [source] When is Commuting Desirable to the Individual?GROWTH AND CHANGE, Issue 3 2004David T. Ory ABSTRACT Commuting is popularly viewed as a stressful, costly, time-wasting experience from the individual perspective, with the attendant congestion imposing major social costs as well. However, several authors have noted that commuting can also offer benefits to the individual, serving as a valued transition between the home and work realms of personal life. Using survey data collected from about 1,300 commuting workers in three San Francisco Bay Area neighborhoods, empirical models are developed for four key variables measured for commute travel, namely: Objective Mobility, Subjective Mobility, Travel Liking, and Relative Desired Mobility. Explanatory variables include measures of general travel-related attitudes, personality traits, lifestyle priorities, and sociodemographic characteristics. Both descriptive statistics and analytical models indicate that commuting is not the unmitigated burden that it is widely perceived to be. About half of the sample were relatively satisfied with the amount they commute, with a small segment actually wanting to increase that amount. Both the psychological impact of commuting, and the amounts people want to commute relative to what they are doing now, are strongly influenced by their liking for commuting. An implication for policy is that some people may be more resistant than expected toward approaches intended to induce reductions in commuting (including, for example, telecommuting). New creativity may be needed to devise policies that recognize the inherent positive utility of travel, while trying to find socially beneficial ways to fulfill desires to maintain or increase travel. [source] ,Do I don't I call the doctor': a qualitative study of parental perceptions of calling the GP out-of-hoursHEALTH EXPECTATIONS, Issue 4 2000Anna M. Houston BSc MA RGN RM RHV The purpose of this study was to investigate how parents use the GP out-of-hours service. There was a lack of information about how parents managed childhood illness and what strategies they put in place to help them to cope before calling the GP. The investigation of parental perceptions was based on a qualitative design using in-depth interviews of 29 families from a semi-rural location in the south-east of England. All parents said they found dealing with a sick child out-of-hours stressful and were concerned to make the right decision for their child. Furthermore, parents usually employed a reasonable strategy in attempting to manage the child's illness. This study demonstrated that the decision to call the doctor was not taken lightly. Many parents had implemented useful strategies prior to calling the doctor. However, most parents were also aware of their limitations and feared doing the wrong thing. It would seem that on occasion this fear combined with factors such as a lack of social support and loss of parental confidence resulted in calling the doctor out of hours to seek ,peace of mind'. A rethink is needed among health professionals about the ,problem' of out-of-hours calls. GPs could actively seek to empower parents by educating them about minor illness during visits and consultations. It is not enough to offer reassurance to parents that their children are fine. Health visitors and other health professionals who come into contact with young families may help to educate and empower. [source] Behavioral arousal in response to stress and drug cue in alcohol and cocaine addicted individuals versus healthy controlsHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 5 2010Tara M. Chaplin Abstract Negative emotional arousal in response to stress and drug cues is known to play a role in the development and continuation of substance use disorders. However, studies have not examined behavioral indicators of such arousal. Objective The current study examined behavioral and bodily arousal in response to stress and drug cue in individuals with alcohol dependence and cocaine dependence as compared to healthy controls using a new scale. Methods Fifty-two alcohol dependent (AD group), 45 cocaine dependent (COC group), and 68 healthy controls (HC group) were exposed to individually developed stressful, drug-cue, and neutral-relaxing imagery. Behavioral and bodily responses were assessed with a new scale, the Behavioral Arousal Scale (BAS). Results The BAS showed acceptable inter-rater reliability and internal consistency and correlated with subjective negative emotion and craving. BAS scores were higher in stress than neutral conditions for all three groups. COC participants showed higher BAS response to stress than AD or HC participants. COC and AD participants showed greater BAS response to drug cue than HC participants. Conclusion Behavioral arousal is a domain in which stress and drug related arousal is expressed and assessment of this domain could provide unique information about vulnerability to craving and relapse in addicted populations.

[source] Violated wishes about division of childcare labor predict early coparenting process during stressful and nonstressful family evaluations,INFANT MENTAL HEALTH JOURNAL, Issue 4 2008Inna Khazan Prior research has indicated that expectant parents overestimate the extent to which fathers will take part in the "work" of parenting, with mothers often becoming disenchanted when these expectations are violated following the baby's arrival. In this study, we examine the role of violated wishes concerning childcare involvement in accounting for variability in maternal and paternal marital satisfaction, and in early coparenting behavior as assessed during family-interaction sessions. The results indicate possible negative effects of violated wishes on the enacted family process and confirm previous findings regarding the effects of marital satisfaction. In addition, we uncovered differences in the way that violated maternal wishes are related to coparenting during playful and mildly stressful family interactions. [source] Causes of hair loss and the developments in hair rejuvenationINTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 1 2002D. H. Rushton Synopsis Hair is considered to be a major component of an individual's general appearance. The psychological impact of hair loss results in a measurably detrimental change in self-esteem and is associated with images of reduced worth. It is not surprising that both men and women find hair loss a stressful experience. Genetic hair loss is the major problem affecting men and by the age of 50, up to 50% will be affected. Initial attempts to regenerate the lost hair have centred on applying a topical solution of between 2% to 5% minoxidil; however, the results proved disappointing. Recently, finasteride, a type II 5, reductase inhibitor has been found to regrow a noticeable amount of hair in about 40% of balding men. Further developments in treatments have lead to the use of a dual type I and type II inhibitor where 90% of those treated regrow a noticeable amount of hair. In women the major cause of hair loss before the age of 50 is nutritional, with 30% affected. Increased and persistent hair shedding (chronic telogen effluvium) and reduced hair volume are the principle changes occurring. The main cause appears to be depleted iron stores, compromised by a suboptimal intake of the essential amino acid l -lysine. Correction of these imbalances stops the excessive hair loss and returns the hair back to its former glory. However, it can take many months to redress the situation. Résumé Les cheveux sont considérés comme étant une composante majeure de l'aspect général d'un individu. L'impact psychologique de la perte des cheveux conduit à une diminution mesurable de l'estime de soi et s'associe à des images de contexte négatif. Il n'est pas surprenant que les hommes comme les femmes ressentent la perte de cheveux comme une expérience stressante. La perte génétique des cheveux est le problème principal qui touche les hommes et autour de l'âge de 50 ans, jusqu'à 50% seront concernés. Les premières tentatives de régénération des cheveux perdus se sont focalisées sur l'application topique d'une solution comprenant entre 2% et 5% de minoxidil; cependant, les résultats se sont avérés décevants. Récemment, le finastéride, un inhibiteur de la 5,-réductase de type II s'est avéré permettre la repousse d'une quantité significative de cheveux chez environ 40% des hommes dégarnis. Les développements ultérieurs des traitements ont conduit à l'utilisation d'un inhibiteur associant type I et type II pour lequel 90% des personnes traitées constatent une repousse significative des cheveux. Chez les femmes la cause principale de la perte des cheveux avant l'âge de 50 ans est d'origine nutritionnelle, avec 30% de la population affectée. Une perte de cheveux persistante et croissante (telogen effluvium chronique) et un volume des cheveux réduit sont les principaux effets qui se produisent. La cause principale semble être des réserves de fer épuisées, associées à une prise insuffisante de l'acide aminé essentiel L-lysine. La correction de ces déséquilibres stoppe la perte excessive de cheveux et rend aux cheveux leur éclat d'antan. Cependant, plusieurs mois peuvent être nécessaires pour redresser la situation. [source] Community psychiatric nurses' experience of working with people who engage in deliberate self-harmINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 3 2008Andrew R. Thompson ABSTRACT:, This paper reports on a study that explored community psychiatric nurses' experiences of working with people who self-harm. Interpretative Phenomenological Analysis was used with eight experienced community psychiatric nurses who participated in semi-structured interviews. Established quality control procedures were utilized including audit of the analysis process and validating the results with participants. The participants described struggling to conceptualize self-harm behaviour and generally reported finding working with people who self-harm stressful particularly in terms of managing the emotional impact upon themselves and the boundaries of their professional responsibilities in relation to managing risk. The therapeutic relationship was viewed as crucial and a variety of coping methods to manage the impact of the work, which had largely developed through ,on the job', experience were described. The results highlight the potential difficulties faced by community staff and can be translated into clear recommendations for training and support. [source] Study abroad as a process of learning intercultural competence in nursingINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 3 2004Liisa Koskinen RN PhD The aim of this research was to describe an international student exchange programme as a context of learning intercultural competence in nursing. Twelve Finnish nursing students who had participated in an exchange programme in the United Kingdom participated. The data consisted of group interviews, learning documents, background questionnaires and research diary notes, and the method of inductive content analysis was used. Study abroad as a process of learning intercultural competence consisted of three ethno-categories: transition from one culture to another, adjustment to the difference and gaining intercultural sensitivity. The exchange programme as a context of learning intercultural competence was characterized by a problematic orientation phase, a study abroad phase that involved stressful but rewarding adjustment to the intercultural differences and an inadequate re-entry debriefing phase. In order for the international experience of nursing students to have an impact on their understanding of diversity, they need assistance in each phase of the programme. Particularly, the students need intercultural tutoring and mentoring to venture into encounters with local people, including direct client contacts, during their study abroad. [source] Barriers for dental treatment of primary teeth in East and West GermanyINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2009CHRISTIAN H. SPLIETH Background., In many countries, restorative treatment in primary teeth is suboptimal. Aim., Thus, this study tried to detect barriers for dentists to restore primary teeth in kindergarten children (3,6 years). Design., For a representative survey, 320 dentists (184 West, 136 East Germany) were randomly selected from the dental associations' registers and asked to answer a questionnaire on their profile, their view of the National Health System, and possible barriers for restoring primary teeth. Results., The analysis (response rate 57.7%) showed that the parents were no barrier and the dentists felt the need of restoring primary teeth. In addition to the children's anxiety, the inadequate reimbursement for fillings were perceived as clear barrier. The comparison of West and East German dentists detected statistically significantly higher barriers in West Germany, where , in contrast to the German Democratic Republic , no structured training in paediatric dentistry was compulsory before unification. Only 35% of the East German dentists rated restorative treatment in 3- to 6-year-olds as stressful in contrast to 65% in West Germany, where especially male dentists found no time to treat children. Conclusion., This study reveals that dentists can also be a considerable barrier to restorative treatment in small children, especially without adequate training in dental schools. [source] Danish dentists' knowledge, attitudes and management of procedural dental pain in children: association with demographic characteristics, structural factors, perceived stress during the administration of local analgesia and their tolerance towards painINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 3 2005J. K. RASMUSSEN Summary., Objective., The aim of the present study was to describe Danish dentists' knowledge of, attitudes towards and management of procedural pain during paediatric dental care, and to assess the importance of demographic characteristics, structural factors, perceived stress during administration of local analgesia and the dentists' own tolerance towards procedural dental pain. Design., A cross-sectional questionnaire study was conducted in Denmark in May 2001. Subjects and methods., The subjects were a random sample of 30% of Danish dentists treating children. Usable information was obtained from 327 (80·3%) of the dentists in the sample. Results., One-quarter of the respondents answered that a 3,5-year-old child could report pain only with uncertainty. More than 80% of the dentists stated that they never compromised on painlessness. Very few agreed to the statement that children forget pain faster than adults. One-third agreed to, or were neutral to, the statement that all restorative care in primary teeth could be performed painlessly using N2O-O2 sedation alone. The majority of the respondents reported using three or more methods to assess the effect of their pain control methods. Almost 90% reported using local analgesia for restorative work ,always' or ,often'. A similar proportion reported using topical analgesia before injection ,always' or ,often'. Administering a mandibular block to preschool children was the procedure perceived as the most stressful (33·6%) pain control method. Demographic factors (gender), structural factors (always working alone and treating 3,5-year-old children daily), perceived stress during the administration of a mandibular block in preschool children and the dentists' own willingness to accept potentially painful dental treatment without local analgesia were associated with knowledge of, attitudes towards and management of procedural dental pain in children. Conclusions., Danish dentists treating children demonstrate concern about procedural dental pain in children. Factors amenable to change via training and reorganization into larger clinical units seem to determine their knowledge of, attitudes towards and management of procedural dental pain in children.

(2010) Recovery after coronary artery bypass surgery: effect of an audiotape information programme. Journal of Advanced Nursing,66(8), 1747,1759. Abstract Title.,Recovery after coronary artery bypass surgery: effect of an audiotape information programme. Aim., The aim of the study was to test the effect of an audiotape giving concrete objective information and strategies to reduce symptoms, psychological distress and enhance physical functioning in patients having coronary artery bypass grafts. Background., The period following hospital discharge is stressful for patients having coronary artery bypass grafts. Evident-based interventions are needed to improve outcomes in Thai populations following coronary artery bypass graft surgery. Methods., A randomized controlled trial was conducted during 2004,2005. A sample of 120 Thai patients having coronary artery bypass grafts was randomly assigned to an intervention group or a control group. The intervention group was given an information audiotape the day prior to hospital discharge, and encouraged to listen to it as many times as necessary. Participants were interviewed using validated instruments predischarge and at 2 weeks and 4 weeks after discharge. Findings., Participants in the intervention group had statistically significantly fewer symptoms of shoulder, back or neck pain and lack of appetite, and increased physical activity after discharge, compared to the control group. This effect remained statistically significant after controlling for age, gender, co-morbidity and presurgical cardiac functional status. However, no statistically significant difference in psychological distress was observed. Conclusion., Nurses can use an audiotape containing preparatory information to improve outcomes for patients having coronary artery bypass grafts during the few weeks after discharge from hospital. Further studies are recommended to improve its effect on psychological distress. [source] Older caregivers' coping strategies and sense of coherence in relation to quality of lifeJOURNAL OF ADVANCED NURSING, Issue 6 2007Anna Kristensson Ekwall Abstract Aim., This paper reports a study to investigate coping strategies and sense of coherence in relation to gender, the extent of care, caregiving activities and health-related quality of life in a population-based sample of caregivers aged 75 and over. Background., Caring for another person can be stressful both emotionally, and caregiver burden may affect quality of life in a negative way for the carer. Caregivers' experience of burden may depend on for example, the behaviour of the person cared for, their own health and their sense of coherence. Older people take a great part of caregiving responsibility and thus understanding of their strain and coping is required. Methods., A postal survey was carried out in 2001 with 171 informal caregivers, aged 75 or older. The response rate was 47%. The questionnaire included the Short-Form 12, Carer's Assessment of Managing Index, and Sense of Coherence instrument. Results., Almost 70% of caregivers provided help every day. Higher health-related quality of life was predicted by using self-sustaining coping strategies and by high sense of coherence. Poor economic situation and demanding social and practical support predicted low scores. Conclusion., These findings could help identify those at risk of low quality of life due to caregiving, dysfunctional coping or lack of information about care. Early intervention, including education about alternative coping strategies and practical information, might allow caregivers better possibilities to continue caring with less negative effects on their lives. [source] A Comparison of Computerized and Pencil-and-Paper Tasks in Assessing Cognitive Function in Community-Dwelling Older People in the Newcastle 85+ Pilot StudyJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2007Joanna Collerton MRCP OBJECTIVES: To compare the acceptability and feasibility of computerized and pencil-and-paper tests of cognitive function in 85-year-old people. DESIGN: Group comparison of participants randomly allocated to pencil-and-paper (Wechsler Adult Intelligence and Memory Scales) or computerized (Cognitive Drug Research) tests of verbal memory and attention. SETTING: The Newcastle 85+ Pilot Study was the precursor to the Newcastle 85+ Study a United Kingdom Medical Research Council/Biotechnology and Biological Sciences Research Council cohort study of health and aging in the oldest-old age group. PARTICIPANTS: Eighty-one community-dwelling individuals aged 85. MEASUREMENTS: Participant and researcher acceptability, completion rates, time taken, validity as cognitive measures, and psychometric utility. RESULTS: Participants randomized to computerized tests were less likely to rate the cognitive function tests as difficult (odds ratio (OR)=0.16, 95% confidence interval (CI)=0.07,0.39), stressful (OR=0.18, 95% CI=0.07,0.45), or unacceptable (OR=0.18, 95% CI=0.08,0.48) than those randomized to pencil-and-paper tests. Researchers were also less likely to rate participants as being distressed in the computer test group (OR=0.19, 95% CI=0.07,0.46). Pencil-and-paper tasks took participants less time to complete (mean±standard deviation 18±4 minutes vs 26±4 minutes) but had fewer participants who could complete all tasks (91% vs 100%). Both types of task were equally good measures of cognitive function. CONCLUSION: Computerized and pencil-and-paper tests are both feasible and useful means of assessing cognitive function in the oldest-old age group. Computerized tests are more acceptable to participants and administrators. [source] Interactive effects of environmental stress and inbreeding on reproductive traits in a wild bird populationJOURNAL OF ANIMAL ECOLOGY, Issue 6 2006A. B. MARR Summary 1Conservation biologists are concerned about the interactive effects of environmental stress and inbreeding because such interactions could affect the dynamics and extinction risk of small and isolated populations, but few studies have tested for these interactions in nature. 2We used data from the long-term population study of song sparrows Melospiza melodia on Mandarte Island to examine the joint effects of inbreeding and environmental stress on four fitness traits that are known to be affected by the inbreeding level of adult birds: hatching success, laying date, male mating success and fledgling survival. 3We found that inbreeding depression interacted with environmental stress to reduce hatching success in the nests of inbred females during periods of rain. 4For laying date, we found equivocal support for an interaction between parental inbreeding and environmental stress. In this case, however, inbred females experienced less inbreeding depression in more stressful, cooler years. 5For two other traits, we found no evidence that the strength of inbreeding depression varied with environmental stress. First, mated males fathered fewer nests per season if inbred or if the ratio of males to females in the population was high, but inbreeding depression did not depend on sex ratio. Second, fledglings survived poorly during rainy periods and if their father was inbred, but the effects of paternal inbreeding and rain did not interact. 6Thus, even for a single species, interactions between the inbreeding level and environmental stress may not occur in all traits affected by inbreeding depression, and interactions that do occur will not always act synergistically to further decrease fitness.

Some concern has been expressed about restraining homing pigeons (Columba livia) in transport crates for sport or for scientific research. Therefore, this study sought to test whether short restraint time in a transport crate for 1, 2 or 18 (overnight) h causes oxidative stress in homing pigeons and whether it is more stressful than flying. To isolate the effect of crowding from that of transport per se, the pigeons were kept in an immobile crate, that is, without any movement. To quantify oxidative stress, we measured serum levels of oxidative damage (ROMs) and of antioxidant capacity (OXY). We found that pigeons restrained in transport crates showed no significant variation for both markers of oxidative stress, regardless of the duration of restraint. Conversely, pigeons which had flown around 200 km had increased levels of oxidative damage and decreased levels of serum OXY, both clear manifestations of oxidative stress. These results suggest that maintaining homing pigeons in transport crates for a short time (i.e. 1,18 h) does not cause oxidative stress. [source] Developmental biology of medaka fish (Oryzias latipes) exposed to alkalinity stressJOURNAL OF APPLIED ICHTHYOLOGY, Issue 3 2010Z. L. Yao Summary Alkalinity stress is common in cultured aquatic animals and considered to be one of the major stress factors for fishes when they are transferred to saline-alkali waters. To evaluate potential effects of alkalinity on the developmental biology of Oryzias latipes, fertilized eggs, larvae and breeding fish were exposed to different carbonate alkalinity concentrations of 1.5,64.5 meq l,1, for 9, 120, and 60 days, respectively. The mortality of embryos significantly increased when exposed to the high concentrations (16.5,64.5 meq l,1). Although more than 50% of survived embryos hatched in 16.5 and 31.4 meq l,1 concentrations of carbonate alkalinity, most were not able to swim up after hatching. Morphological abnormalities such as coagulated embryos, halted embryo development, and hatching failure were observed at stages 15, 29,33 and 38 in high concentrations (31.4, 64.5 meq l,1). Almost all larvae in 16.5 and 31.4 meq l,1 treatments died 70 d post-hatch. Growth of juveniles exposed to carbonate alkalinity of 5.3 and 8.8 meq l,1 was not significantly different at 70 d and 120 d post-hatch. The number of eggs released by breeders, the fertilization rate and the hatching rate of eggs were significantly lower in the 31.4 meq l,1 treatment than in other treatments. Although medaka are capable of surviving in high alkalinities (31.4, 64.5 meq l,1) for an extended period of time, these conditions are stressful to the fish, especially at the embryonic and reproductive stages. [source] Mitigating stress effects during transportation of matrinxã (Brycon amazonicus Günther, 1869; Characidae) through the application of calcium sulfateJOURNAL OF APPLIED ICHTHYOLOGY, Issue 2 2009F. Bendhack Summary This study verified the effects of CaSO4 on physiological responses of the tropical fish matrinxãBrycon amazonicus (200.2 ± 51.1 g) in water containing CaSO4 after a 4-h transportation at concentrations of: 0, 75, 150, and 300 mg L,1. Blood samples were collected prior to transportation (initial levels), immediately after packaging, at arrival, and 24 h and 96 h after transportation (recovery). Cortisol levels increased after packaging (118.2 ± 14.2 ng ml,1), and decreased slightly after transportation in water containing CaSO4 (106.8 ± 14.1), but remained higher than initial levels (21.0 ± 2.6 ng ml,1). Fish kept at 150 mg L,1 CaSO4 reached the pre-transportation levels at 24 h of recovery. Blood glucose increased after transportation in all treatments (8.2 ± 0.2 mmol L,1) and declined after full recovery to values below initial levels (4.8 ± 0.1 mmol L,1). Chloride levels did not change in CaSO4 treatments; serum sodium concentrations decreased after packaging and after transportation. Serum calcium levels did not differ among treatments, but decreased after packaging and increased at 96 h of recovery. Hematocrit and the number of red blood cells were higher in all treatments after packaging and arrival, except in fish exposed to 300 mg L,1 CaSO4. Mean corpuscular volume increased in 75 mg L,1 CaSO4, which reached the higher VCM after transportation. Hemoglobin levels increased only after transportation, regardless of calcium sulfate levels. Handling before transportation and transportation itself were both stressful to fish; calcium sulfate at concentrations tested in the present work had a moderate influence in the reduction of stress responses. [source] Mortality of Parents of People with Intellectual DisabilitiesJOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 1 2002Andrew J. Hill-Smith Background The experience of caring for a son or daughter with an intellectual disability has long been recognized as stressful. The long-term health costs for parents of people with intellectual disability have attracted some recent research attention, but mortality has not been studied. Methods The present authors examined mortality as measured by the standardized mortality ratio (SMR), and cause of death for parents of people with intellectual disability, identified through an intellectual disability register in Merton, south London. Results Although there was a trend for lower SMRs particularly for mothers, SMRs were not significantly different from unity. Subgroups of parents whose child was cared for predominantly in an institution, or in the family home were analysed and similarly showed no significant difference from unity. The same applied to cause of death analyses. Conclusions These findings offer some reassurance to parents of people with intellectual disability. There is an urgent need for further research in this area. [source] Gizzard and other lean mass components increase, yet Basal Metabolic Rates decrease, when red knots Calidris canutus are shifted from soft to hard-shelled foodJOURNAL OF AVIAN BIOLOGY, Issue 2 2004Theunis Piersma We measured basal metabolic rate (BMR), body mass, lean mass, and gizzard mass of captive red knots Calidriscanutusislandica maintained on a trout chow diet (soft-texture, low ash and water content) for several years and then shifted to small mussels Mytilus edulis (hard-texture, high ash and water content). During a 3-week period of feeding on mussels, body mass, lean mass, and gizzard mass increased 7.3 g (+7%), 10.5 g (+12%), and 4.9 g (+213%), respectively, yet BMR decreased from 0.96 to 0.89 W (,8%). Under the new mussel regime, red knots must have reduced the metabolic intensity of some of the tissues. This suggests that the experimental red knots experienced the transition to a mussel diet as stressful and energy limiting, resulting in an energy-saving strategy by reducing BMR in spite of hypertrophy of the gizzard and other organs. [source] A Support Group Intervention for Children Bereaved by Parental SuicideJOURNAL OF CHILD AND ADOLESCENT PSYCHIATRIC NURSING, Issue 1 2007Ann M. Mitchell PhD TOPIC:,Bereavement is considered by many to be among the most stressful of life events, and it becomes particularly distressing when it concerns the suicide death of a parent. Such an event is especially traumatic for children. PURPOSE AND SOURCES:,The purpose of this paper is to present a case for support group interventions designed specifically for child survivors of parental suicide. The authors provide a theoretical framework for supportive group interventions with these children and describe the structure of an 8-week bereavement support group for this special population of suicide survivors. CONCLUSIONS:,A case is made for designing and implementing group interventions to meet the mental health needs of this important group of individuals. [source] The challenge of caring for patients in pain: from the nurse's perspectiveJOURNAL OF CLINICAL NURSING, Issue 20 2009Katrin Blondal Aim., To increase understanding of what it is like for nurses to care for patients in pain. Background., Hospitalised patients are still suffering from pain despite increased knowledge, new technology and a wealth of research. Since nurses are key figures in successful pain management and research findings indicate that caring for suffering patients is a stressful and demanding experience where conflict often arises in nurses' relations with patients and doctors, it may be fruitful to study nurses' experience of caring for patients in pain to increase understanding of the above problem. Design., A phenomenological study involved 20 dialogues with 10 experienced nurses. Results., The findings indicate that caring for a patient in pain is a ,challenging journey' for the nurse. The nurse seems to have a ,strong motivation to ease the pain' through moral obligation, knowledge, personal experience and conviction. The main challenges that face the nurse are ,reading the patient', ,dealing with inner conflict of moral dilemmas', ,dealing with gatekeepers' (physicians) and ,organisational hindrances'. Depending upon the outcome, pain management can have positive or negative effects on the patient and the nurse. Conclusions., Nurses need various coexisting patterns of knowledge, as well as a favourable organisational environment, if they are to be capable of performing in accord with their moral and professional obligations regarding pain relief. Nurses' knowledge in this respect may hitherto have been too narrowly defined. Relevance to clinical practice., The findings can stimulate nurses to reflect critically on their current pain management practice. By identifying their strengths as well as their limitations, they can improve their knowledge and performance on their own, or else request more education, training and support. Since nurses' clinical decisions are constantly moulded and stimulated by multiple patterns of knowledge, educators in pain management should focus not only on theoretical but also on personal and ethical knowledge.
