The effect of metoprolol and aspirin on cardiovascular risk in bereavement: A randomized controlled trial.

BACKGROUND: Bereavement is associated with an increased risk of cardiovascular disease; however, no reports exist of interventions to reduce risk. In a randomized, double-blind, placebo-controlled trial of 85 recently bereaved participants, we determined whether ß-blocker (metoprolol 25 mg) and aspirin (100 mg) reduce cardiovascular risk markers and anxiety, without adversely affecting bereavement intensity. METHODS: Participants were spouses (n = 73) or parents (n = 12) of deceased from 5 hospitals in Sydney, Australia, 55 females, 30 males, aged 66.1 ±â€¯9.4 years. After assessment within 2 weeks of bereavement, subjects were randomized to 6 weeks of daily treatment or placebo, and the effect evaluated using ANCOVA, adjusted for baseline values (primary analysis). RESULTS: Participants on metoprolol and aspirin had lower levels of home systolic pressure (P = .03), 24-hour average heart rate (P < .001) and anxiety (P = .01) platelet response to arachidonic acid (P < .001) and depression symptoms (P = .046) than placebo with no difference in standard deviation of NN intervals index (SDNNi), von Willebrand Factor antigen, platelet-granulocyte aggregates or bereavement intensity. No significant adverse safety impact was observed. CONCLUSIONS: In early bereavement, low dose metoprolol and aspirin for 6 weeks reduces physiological and psychological surrogate measures of cardiovascular risk. Although further research is needed, results suggest a potential preventive benefit of this approach during heightened cardiovascular risk associated with early bereavement.

Predicting Weight Gain in Patients Treated With Clozapine: The Role of Sex, Body Mass Index, and Smoking.

OBJECTIVES: Weight gain on clozapine is highly variable and poorly predictable. Its mechanisms are not well understood. This study explores the factors that predict weight gain between 3 and 12 months of clozapine therapy in community-dwelling patients. METHODS: We conducted a retrospective audit of patients attending an outpatient clozapine clinic. Weight change from 3 to 12 months of therapy was recorded, expressed as a percentage of the 3-month weight. Univariate analyses compared percent weight change according to sex, smoking status, country of birth, and baseline body mass index. Correlations between weight gain, age, and clozapine dose were explored. A general linear model identified independent predictors of weight gain. RESULTS: The mean weight change from 3 to 12 months in 117 patients was +3.1% (range, -17% to +30%). Females gained more weight than males (+5.5% vs +1.3%, P = 0.01), smokers gained more than nonsmokers (+5.1% vs +1.2%, P = 0.02), and obese patients gained less than normal or overweight individuals (0.15% vs 4.6% and 5.2%, respectively, P = 0.01). Age and clozapine dose had no relation to weight change. On multivariate analysis, baseline BMI and smoking status remained independent predictors of percent weight change in females. These 2 predictors explained 25% of weight change in females in the first 3 to 12 months of therapy. These associations were not observed in males. CONCLUSIONS: We hypothesize that smoking affects weight change by promoting clozapine metabolism to norclozapine via cytochrome P450 enzymes. Verifying this hypothesis and exploring the mechanisms underpinning the sex dichotomy are areas for further research.

Religiosity, spirituality in relation to disordered eating and body image concerns: A systematic review.

OBJECTIVE: This systematic review aims to critically examine the existing literature that has reported on the links between aspects of religiosity, spirituality and disordered eating, psychopathology and body image concerns. METHOD: A systematic search of online databases (PsycINFO, Medline, Embase and Web of Science) was conducted in December 2014. A search protocol was designed to identify relevant articles that quantitatively explored the relationship between various aspects of religiosity and/or spirituality and disordered eating, psychopathology and/or body image concerns in non-clinical samples of women and men. RESULTS: Twenty-two studies were identified to have matched the inclusion criteria. Overall, the main findings to emerge were that strong and internalised religious beliefs coupled with having a secure and satisfying relationship with God were associated with lower levels of disordered eating, psychopathology and body image concern. Conversely, a superficial faith coupled with a doubtful and anxious relationship with God were associated with greater levels of disordered eating, psychopathology and body image concern. DISCUSSION: While the studies reviewed have a number of evident limitations in design and methodology, there is sufficient evidence to make this avenue of enquiry worth pursuing. It is hoped that the direction provided by this review will lead to further investigation into the protective benefits of religiosity and spirituality in the development of a clinical eating disorder. Thus a stronger evidence base can then be utilised in developing community awareness and programs which reduce the risk.

The nature of death, coping response and intensity of bereavement following death in the critical care environment.

INTRODUCTION: Bereavement, defined as the situation of having recently lost a significant other, is recognised as one of life's greatest stressors and may lead to decrements in health status, psychological morbidity and excess risk of mortality. AIM: The aim of this study was firstly to describe the relationships between the nature of death and bereavement intensity following death in the adult critical care environment and secondly to examine the modifying effects of coping responses on intensity of bereavement reaction. METHOD: Prospective evaluation of the impact of the nature of death and coping responses on bereavement intensity. 78 participants completed a nature of death questionnaire within 2 weeks of bereavement and at 3 and 6 months completed the Core Bereavement Items Questionnaire (CBI-17) and Brief COPE Inventory. RESULTS: At 6 months, univariate variables significantly associated with bereavement intensity were: being unprepared for the death (p<0.001), a drawn out death (p<0.001), a violent death (p=0.007) and if the deceased appeared to suffer more than expected (p=0.03). Multivariate analysis revealed being unprepared for the death appears to account for these relationships. Regarding coping, there were significant increases from 3 to 6 months in both acceptance scales (p=0.01) and planning (p=0.02) on The Brief COPE Inventory. Greater use of emotional support (p=0.02), self-blame (0.003) and denial (p<0.001) were multivariate variables associated with higher bereavement intensity at 6 months. CONCLUSION: The results from this evaluation provide insight into the impact of bereavement after death in the critical care environment and inform potential preventative approaches at the time of death to reduce bereavement intensity.

The complexities of recruiting bereaved family members into a research study in the critical care environment: a discussion paper.

Research on the effects of stressful events on human health and wellbeing has progressed in recent years. One such stress, bereavement, is considered one of life's greatest stresses, requiring significant readjustment. The Cardiovascular Risk in Bereavement study (CARBER) investigated in detail cardiovascular risk factors during the first weeks following the death of a partner or adult child in the critical care environment. The purpose of this paper is to explore the once held perception that the bereaved population should not be involved in research, using an actual illustrative project. The paper specifically focuses on the challenges regarding acceptability and feasibility of recruitment of recently bereaved individuals from the critical care environment. The question of whether bereaved individuals have capacity to consent to involvement in research immediately after loss is considered. The appropriateness of asking newly bereaved individuals to participate in research immediately after the death of their relative is also discussed. The work of the research team demonstrates that early recruitment of bereaved family members into a research project is feasible and acceptable to participants, especially when a multidisciplinary collaborative approach is employed and a personal mode of recruitment used.

Developing a model of associations between chronic pain, depressive mood, chronic fatigue, and self-efficacy in people with spinal cord injury.

UNLABELLED: Chronic pain, chronic fatigue, and depressive mood are prevalent conditions in people with spinal cord injury (SCI). The objective of this research was to investigate the relationship between these conditions in adults with SCI. Multivariate analysis of variance, contingency analyses, and hierarchical regression were used to determine the nature of the relationship, as well as the contribution to this relationship of self-efficacy, a potential mediator variable. Seventy participants with SCI living in the community completed an assessment regimen of demographic and psychometric measures, including validated measures of pain, fatigue, depressive mood, and self-efficacy. Results indicated that participants with high levels of chronic pain had clinically elevated depressive mood, confusion, fatigue, anxiety and anger, low vigor, and poor self-efficacy. Participants with high chronic pain had 8 times the odds of having depressive mood and 9 times the odds of having chronic fatigue. Regression analyses revealed that chronic pain contributed significantly to elevated depressive mood and that self-efficacy mediated (cushioned) the impact of chronic pain on mood. Furthermore, both chronic pain and depressive mood were shown to contribute independently to chronic fatigue. Implications of these results for managing chronic pain in adults with SCI are discussed. PERSPECTIVE: The relationship between pain, negative mood, fatigue, and self-efficacy in adults with SCI was explored. Results support a model that proposes that chronic pain lowers mood, which is mediated (lessened) by self-efficacy, whereas pain and mood independently increase chronic fatigue. Results provide direction for treating chronic pain in SCI.

Effect of early bereavement on heart rate and heart rate variability.

Early bereavement is associated with increased cardiovascular events. The mechanism, however, has not been well studied. We assessed whether bereavement is associated with an increased heart rate (HR) and decreased heart rate variability that might contribute to increased cardiovascular risk. A total of 78 bereaved spouses and parents (55 women and 23 men; aged 34 to 87 years, mean 65) were studied with 24-hour Holter monitoring within 2 weeks of bereavement (acute) and at 6 months. Their findings were compared to those from a nonbereaved reference group (52 women and 27 men) aged 33 to 91 years (mean 63.6). All participants were in sinus rhythm. We assessed the mean HR, atrial and ventricular arrhythmias, and both time and frequency domain heart rate variability measures. Acute bereavement was associated with increased 24-hour HR (mean ± SE, 75.1 ± 1.1 vs 70.7 ± 1.0; p = 0.004) and reduced heart rate variability, as indicated by lower standard deviation of the NN intervals index (median 45.4 vs 49.9, p = 0.017), total power (7.78 ± 0.10 vs 8.02 ± 0.09, p = 0.03), very low frequency (7.23 ± 0.09 vs 7.44, p = 0.046) and low frequency (5.76 ± 0.12 vs 6.16 ± 0.09, p = 0.01). At 6 months, the bereaved had a significantly lower HR (p = 0.001) and increased standard deviation of the NN intervals index (p = 0.02), square root of the mean square of differences of successive intervals (p = 0.045), number of interval differences of successive NN intervals >50 ms divided by the number of NN intervals (p = 0.039), low-frequency power (p = 0.02), and high frequency (p = 0.002) compared to the initial acute levels. In conclusion, the present study, the first to report 24-hour HR monitoring in the early weeks of bereavement, has demonstrated increased HR and altered autonomic function that might contribute to the increased cardiovascular events in early bereavement.

Physiological correlates of bereavement and the impact of bereavement interventions.

The death of a loved one is recognized as one of life's greatest stresses, with reports of increased mortality and morbidity for the surviving spouse or parent, especially in the early months of bereavement. The aim of this paper is to review the evidence to date to identify physiological changes in the early bereaved period, and evaluate the impact of bereavement interventions on such physiological responses, where they exist. Research to date suggests that bereavement is associated with neuroendocrine activation (cortisol response), altered sleep (electroencephalography changes), immune imbalance (reduced T-lymphocyte proliferation), inflammatory cell mobilization (neutrophils), and prothrombotic response (platelet activation and increased vWF-ag) as well as hemodynamic changes (heart rate and blood pressure), especially in the early months following loss. Additional evidence suggests that bereavement interventions have the potential to be of value in instances where sleep disturbance becomes a prolonged feature of complicated grief, but have limited efficacy in maintaining immune function in the normal course of bereavement.

Inflammatory and thrombotic changes in early bereavement: a prospective evaluation.

AIMS: Although there is an increased cardiovascular risk in the immediate weeks following bereavement, the mechanism is not well understood. The aim of this study was to determine whether inflammatory and thrombotic changes were present in acute bereavement. METHODS AND RESULTS: Eighty bereaved spouses or parents were prospectively studied within 2 weeks of bereavement (acute) and at 6 months, and compared to 80 non-bereaved participants. Haemostatic measures were obtained between 8 a.m. and 11 a.m. and processed within 1 h. Compared to non-bereaved participants, those acutely bereaved had a higher neutrophil count (4.34 ± 0.19 vs 3.79 ± 0.15, p = <0.001), von Willebrand factor antigen (132.33 ± 3.6 vs 119.95 ± 3.29, p = 0.02), Factor VIII (1.43 ± 0.06 vs 1.25 ± 0.04, p = 0.02) and platelet/granulocyte aggregates (median 383.0 vs 343.5, p = 0.02). Levels of neutrophils, monocytes, eosinophils, platelet count, platelet/monocyte granulocytes and von Willebrand factor were lower in bereaved at 6 months compared to acutely (all p < 0.05). CONCLUSION: Acute bereavement is associated with inflammatory and prothrombotic changes that may contribute to the increased cardiovascular risk with bereavement and provide clues for future preventative strategies.

Concordance between Sources of Morbidity Reports: Self-Reports and Medical Records.

As part of a 10-year follow-up study of morbidity following spouse bereavement, concordance between subject reports of their illness experience and that given by their doctors' and other medical records has been assessed. Enumeration from medical records involved extensive and careful perusal of general practitioner, specialist, and hospital records while subject reports were aided by a structured questionnaire which helped to prompt subjects' memories. The findings showed generally poor concordance between these two sources of morbidity data. Overall only 22% of disease events were found in both sources: of the diseases that did not match 65% were from the record source and 35% were from the self-report source. Despite finding that concordance rates varied with some subject and disease factors, concordance was always less than might be expected to occur by random chance (the throw of a coin). These findings have serious implications for epidemiological and pharmacoeconomic research involving morbidity history as they suggest that neither the subject nor their medical record can generally be assumed to provide a complete enumeration of morbidity burden. Indeed, irrespective of the significant factors under consideration, the maximum concordance reached in this study was 45.7%.

Haemodynamic changes during early bereavement: potential contribution to increased cardiovascular risk.

BACKGROUND: bereavement is associated with increased cardiovascular risk, particularly in surviving spouses and parents, however the mechanism is not well understood due to limited studies. The purpose of this study was to evaluate haemodynamic changes (blood pressure (BP) and heart rate (HR)), that may contribute to increased cardiac risk in early bereavement. METHODS: we enrolled 80 bereaved individuals and 80 non-bereaved as a reference group. Twenty-four hour ambulatory blood pressure monitoring was performed within two weeks (acute assessment) and at six months following bereavement. RESULTS: compared to the non-bereaved, the acutely bereaved had higher 24-hour systolic BP (mean (SE) 130.3 (1.5) vs 127.5 (1.4)mmHg, p=0.03), higher daytime systolic BP (135.6 (1.5) vs 131.6 (1.4)mmHg, p=0.02) and higher daytime systolic load (median % 39.0 vs 29.3, p=0.02). By six months the BP of the bereaved tended to be lower than acute measures. This difference was significant amongst those not taking BP lowering medications for 24-hour systolic BP (126.5 (2.4) vs 129.7 (2.3)mmHg, p=0.04), daytime systolic BP (129.8 (2.1) vs 133.9 (2.0)mmHg, p=0.01) and daytime diastolic pressure (76.7 (1.0) vs 78.9 (0.9)mmHg, p=0.03). Twenty-four hour heart rate was also higher acutely in the bereaved compared with the reference group (74.0 (1.2) vs 71.7 (0.9) b/min, p=0.02); at six months heart rate in the bereaved had fallen to non-bereaved levels (70.4 (0.09), p=0.02). CONCLUSION: early bereavement is associated with increased systolic blood pressure and heart rate. These haemodynamic changes may contribute to a time-limited increase in cardiovascular risk.

Smoking cessation through a novel behavior modification technique.

Smoking remains a major public health problem. Experiencing a myocardial infarction (MI) can be a teachable moment that results in smoking cessation when previous efforts have failed. We tested the feasibility of providing a simulated and personalized experience of an MI to facilitate quitting smoking. Smokers, who were recruited from the community, had photographs taken of themselves, their partner, and family. These photographs were inserted into a video depicting the subject as a smoker experiencing an MI with potential consequences to themselves (death or disability) and their family. The subject watched the video and a psychologist used motivational interviewing to reinforce quitting efficacy. Thirteen subjects (11 men, 2 women) 45 +/- 12 years of age with no smoking-related illness and a nonsmoking partner were studied. At week 1, 7 of 13 subjects (54%) reported stopping smoking, and the other 6 had decreased consumption. Daily cigarette consumption at week 1 decreased from 17.3 +/- 9.3 at baseline to 2.7 +/- 4.9 (p <0.005) and expired carbon monoxide levels from 15.7 +/- 9 to 3.1 +/- 3.2 parts per million (p <0.005). Seven subjects had observable responses to the video including "looking uncomfortable" and "red eyes, difficulty speaking." Self-reports included "made me aware of the important things" and "it felt very real." At 6 months, 7 of 13 subjects (54%) were still abstinent. Five of the 7 nonsmoking subjects used an additional antismoking aid. In conclusion, it is feasible to create a simulated and personalized teachable moment and these findings provide encouragement for evaluating this novel method for smoking cessation and other behavior modifications.

The effect of music on brain wave functioning during an acute psychotic episode: a pilot study.

This pilot study compared the differences in the quantified electroencephalogram (qEEG) between two conditions; eyes closed resting and eyes closed listening to music of 15 subjects currently experiencing an acute psychotic episode. The results showed a significant decrease in delta, alpha and beta waves when listening to music compared to resting condition.

Cardiovascular risk in early bereavement: a literature review and proposed mechanisms.

OBJECTIVES: The purpose of this review was to examine the evidence of cardiovascular risk in early bereavement to identify potential risk factors and possible mechanisms for risk that may inform future research directions. DESIGN: A comprehensive search of electronic databases PubMed Medline, CINAHL and PsycINFO, bereavement related textbooks and reviewed reference lists was undertaken on literature related to evidence of increased risk in bereavement. No limits were set on the searches in terms of date or publication type, but only English language articles were selected. FINDINGS: Bereavement represents a time of heightened cardiovascular risk for the surviving spouse. The immediate weeks following bereavement represent the highest risk period with both men and women across all ages. Risk is evident irrespective of the nature of death, expected or unexpected, although higher level of social support at the time of death may be protective. Evidence would suggest that for many, bereavement results in a time of increased psychological stress and potential for altered behavioural health risk factors that in the presence of altered physiological state, may serve as a potential trigger of cardiovascular events, especially in those most at risk. CONCLUSION: The findings from this review provide insight into the impact of early bereavement on health and the recognition that bereavement is associated with increased cardiac risk. This recognition should provide an impetus for individuals to act on cardiac symptoms by seeking medical advice and for health care providers to monitor such individuals more closely.

The long-term impact of bereavement upon spouse health: a 10-year follow-up.

UNLABELLED: Jones MP, Bartrop RW, Forcier L, Penny R. The long-term impact of bereavement upon spouse health: a 10-year follow-up. OBJECTIVES: This study is the first to examine the effect of bereavement of a first-degree family member on subsequent morbidity over a 10-year follow-up period. METHODS: A sample of bereaved subjects (n = 72) were compared with a control group (n = 80) recruited in the same period with respect to morbidity experience during follow-up. Morbidity events were ascertained from the subject themselves, their health care providers and these sources were also compared. RESULTS: Bereavement was associated with an elevated total burden of illness as well as with mental health and circulatory system categories diagnosed according to the International Classification of Diseases - Clinically Modified (ICD-9) classification system. The elevation ranged from approximately 20% for any illness to 60-100% among circulatory system disorders. Although in an earlier study there was a downregulation of T-cell function in the bereaved during the first 8 weeks, there was no evidence that the bereavement was associated with increased morbidity in the respiratory or immune system ICD-9 categories long-term. CONCLUSIONS: Past epidemiological research has indicated that bereavement of a close family member is associated with adverse health consequences of a generalised morbidity. Our study suggests an increase in mental health and circulatory system effects in particular. Further research is required to determine whether other systems are also affected by bereavement.

Pubertal process and green-sickness in Renaissance drama: a form fruste of anorexia nervosa?

OBJECTIVE: The aim of this paper is to investigate the relationship between puberty and the onset of green-sickness in early modern popular culture with findings on puberty and the onset of anorexia nervosa. METHOD: Four plays from the late 16th and early 17th centuries dealing with 14-15-year-old girls were analysed for information on puberty and for precipitating factors for the onset of green-sickness. These were then contrasted with the literature on anorexia nervosa where puberty has been proposed as a potential risk factor for the development of the disorder. RESULTS: These four plays endorse a common understanding in early modern popular culture that puberty presents a major developmental challenge for young women. Four common precipitating factors for the development of green-sickness were identified: socio-economic status; age at onset; nutrition and sexual development. These have a striking resemblance to our current understanding of the development of anorexia nervosa in adolescence. CONCLUSION: Green-sickness shares certain similarities with anorexia nervosa. It is a post menarcheal condition arising out of the body's ripeness for reproduction at around the age of 14. Affluence and improved nutrition were recognized as contributory factors. The development of both green-sickness and anorexia nervosa appear to share a common theme in the context of puberty.

Immunological disturbance and infectious disease in anorexia nervosa: a review.

OBJECTIVE: Severely malnourished patients with anorexia nervosa (AN) are reported to show fewer symptomatic viral infections and a poorer response to bacterial infection than controls. They are also reported to show mild immune system changes, although the relevance of these to altered infection disease presentation in AN and AN pathophysiology is unknown. Thus, in this paper, we suggest a range of immune system changes that might underpin these altered responses to common pathogens, and review a number of recent infectious disease findings for their utility in explaining the pathophysiology of AN. METHODS: A systematic review of the literature pertaining to immunity and infectious disease in AN was performed. RESULTS: AN is associated with leucopenia, and the increased spontaneous and stimulated levels of proinflammatory cytokines [i.e. interleukin (IL)-1ß, IL-6 and tumour necrosis factor α). A range of less consistent findings are also reviewed. Most of these data were not controlled for length of illness, degree of malnutrition, micronutrient or vitamin deficiencies or recent refeeding and starvation. CONCLUSION: Cytokine disturbances have been suggested to be causally related to AN symptomatology and pathophysiology of AN, although the evidence supporting this assertion is lacking. Immune and cytokine changes in AN do, however, occur in association with a decreased incidence of symptomatic viral infection, decreased clinical response to bacterial infection leading to delayed diagnosis and increased morbidity and mortality associated with the infections.

Bacterial infections in anorexia nervosa: delayed recognition increases complications.

OBJECTIVE: We compared the natural history of bacterial infection in patients with anorexia nervosa (AN) with controls, and assessed which of a range of patient characteristics were associated with infection, fever response, and the rate of infectious complications in AN patients. METHOD: The charts of 311 consecutive hospital admissions of AN patients were reviewed. Patients who had a bacterial infection while in the hospital were compared with the AN patients who did not have an infection, with respect to a range of demographic and disease variables. Fever response and infection complication rate also were evaluated in AN patients with a bacterial infection and in nonanorectic control subjects admitted with a bacterial infection. RESULTS: AN patients with a bacterial infection showed a reduced fever response, were often difficult to diagnose because of fewer signs and symptoms, and infection became more frequent with increasing patient age. DISCUSSION: A reduction in fever response and the signs and symptoms of infection significantly delayed diagnosis in AN patients and increased the complication rate from bacterial infection. We recommend that an increased index of suspicion and an early complete blood count and bacteriologic cultures be adopted for the investigation of bacterial infection in AN patients.
