Role of patients' view of their illness in predicting return to work and functioning after myocardial infarction: longitudinal study

Comparing Patients' Perceptions of Dry Eye Disease Between Spanish- and English-Speaking Patients in the United States

PURPOSE

It is well-known that patients' perceptions of their disease can impact management strategies and disease outcomes. Limited knowledge exists on such perceptions in dry eye disease (DED) and the role of language in these perceptions. Herein, we compared the perceptions about DED between Spanish- and English-speaking patients.

METHODS

This cross-sectional study included 146 patients with DED who underwent ophthalmic evaluation and completed questionnaires assessing their perceptions of DED on a 10-point scale during their routine appointments. Perceptions included opinions on the level of satisfaction with understanding of DED, ease of following doctor's advice, effectiveness of treatment, satisfaction with DED care, and outlook on DED. Perceptions were categorized as low (scores 0-2), moderate (scores 3-7), and high (scores 8-10). The percentage of patients with high perception scores were then compared between Spanish- and English-speaking patients.

RESULTS

There were 48 Spanish speakers and 98 English speakers. Overall, high scores of DED perceptions were identified in 47.9% for satisfaction with the level of understanding of DED, 72.6% for ease of following doctor's advice, 52.1% for helpfulness of DED treatment, 64.4% for satisfaction with DED care, and 52.1% for optimistic outlook on DED. High scores for satisfaction with the level of understanding of DED were significantly lower in Spanish speakers (27.1%) than English speakers (58.2%, p < .001). No significant differences were observed in other perceptions between Spanish- and English-speaking participants.

CONCLUSIONS

Spanish-speaking subjects reported lower satisfaction with their understanding of DED than English speakers. Clinicians should provide health services and educational materials in the patient's preferred language to minimize barriers to understanding their disease.

Do labels matter? Implications of ongoing symptomatic chronic illnesses labeled as conventional diagnoses vs. functional somatic syndromes

OBJECTIVE

A consideration of chronic illness according to illness labels that are medically understood as opposed to being outside of medical understanding may reveal unique differences in how individuals understand their illness and how such lay understandings relate to health-related quality of life. Study aims are framed according to the commonsense model of self-regulation with a focus on characterizing illness representations according to chronic illness diagnosis type.

METHODS

Individuals suffering from symptomatic chronic illnesses (n  =  192) completed measures of illness representations, coping, and general health. Participants were categorized into one of two groups based on reported diagnosis/symptoms: (a) conventional diagnosis (CD) or (b) functional somatic syndrome (FSS).

RESULTS

FSS participants reported lower illness coherence and greater illness identity than CD participants. Overall, illness coherence predicted negative coping which mediated the relationship between illness coherence and general health.

CONCLUSIONS

Minimal differences were found in illness representations across FSS and CD groups with distinctions found only for illness coherence and identity. Illness coherence stands out as particularly important for coping and health-related quality of life for individuals with ongoing symptoms. Healthcare professionals should work carefully with chronically ill populations to address potential impacts of illness coherence, especially among FSS patients.

Can acutely ill patients predict their outcomes? A scoping review

INTRODUCTION

The full impact of an acute illness on subsequent health is seldom explicitly discussed with patients. Patients' estimates of their likely prognosis have been explored in chronic care settings and can contribute to the improvement of clinical outcomes and patient satisfaction. This scoping review aimed to identify studies of acutely ill patients' estimates of their outcomes and potential benefits for their care.

METHODS

A search was conducted in PubMed, Embase, Web of Science and Google Scholar, using terms related to prognostication and acute care. After removal of duplicates, all articles were assessed for relevance by six investigator pairs; disagreements were resolved by a third investigator. Risk of bias was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions.

RESULTS

Our search identified 3265 articles, of which 10 were included. The methods of assessing self-prognostication were very heterogeneous. Patients seem to be able to predict their need for hospital admission in certain settings, but not their length of stay. The severity of their symptoms and the burden of their disease are often overestimated or underestimated by patients. Patients with severe health conditions and their relatives tend to be overoptimistic about the likely outcome.

CONCLUSION

The understanding of acutely ill patients of their likely outcomes and benefits of treatment has not been adequately studied and is a major knowledge gap. Limited published literature suggests patients may be able to predict their need for hospital admission. Illness perception may influence help-seeking behaviour, speed of recovery and subsequent quality of life. Knowledge of patients' self-prognosis may enhance communication between patients and their physicians, which improves patient-centred care.

Factors That Predict Early Return to Work After Myocardial Infarction: Importance of Coworker Support

Aim    Myocardial infarction (MI) affects the working-age group and cause many absences and lost days of work. Some occupational factors effect in the prognosis of MI patients. The objective of this study was to determine predictors of early, late and no return to work (RTW) after MI.Material and methods    In this cohort study, 240 pre-employed, male patients with MI from April 2020 through February 2022 provided data about their demographic, occupational, psychosocial, and medical information. Data was also collected about the treatment they received as patients, their feelings about socioeconomic support, and RTW time. RTW within two weeks after MI was defined as early RTW. The relationships of these variables and with early RTW and with late or no RTW were analyzed.Results    Ninety-four patients (39.6 %) returned to work within two weeks after MI, whereas 207 patients (87.3 %) returned to work by the end of six months. Many variables, including coworker support, were associated with early RTW in a univariate analysis. Regression analysis revealed that age, coworker support, marital status, the patient's own estimated RTW time, the number of the vessels with occlusion, and comorbidity were predictors of early RTW. Of these factors, only coworker support would be subject to modification.Conclusions    This study indicates that improving support from coworkers can increase early RTW after MI.

The illness perceptions of patients with percutaneous coronary intervention compared to patients with no percutaneous intervention, for acute myocardial infarction, in cardiac rehabilitation

PURPOSE

Patients who receive percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) have been found to have low attendance at cardiac rehabilitation (CR). It has been suggested that this is because PCI patients have a benign perception of their coronary disease; however, this has never been quantitatively investigated. The aim of this prospective study was to evaluate the illness perceptions (IP) of patients with AMI treated with PCI.

METHODS

The Heart Health Illness Perception Questionnaire (modified version of the Brief Illness Perception Questionnaire) and the Cardiac Beliefs Questionnaire were used to assess patients' IP and cardiac disease misconceptions, respectively. Patients in phase 2 of CR were recruited from the Royal Alexandria Hospital, Paisley, UK. One hundred two patients were identified from the cardiac unit database over a 16-week period and sent questionnaires.

RESULTS

Fifty-six patients returned questionnaires suitable for analysis (54.9% response rate). There was a significant difference in the IP scores of the 3 groups [primary-PCI (pPCI) = 0.18 ± 1.44, elective-PCI = 5.27 ± 15.65, non-PCI = 9.94 ± 11.19; P = 0.046]. PCI patients had a significantly lower IP score than non-PCI patients (PCI = 1.62 ± 12.76, non-PCI = 9.94 ± 11.19; P = 0.027). pPCI patients had a significantly lower IP score than non-pPCI patients (pPCI = 0.18 ± 11.44, non-pPCI = 8.04 ± 13.11; P = 0.021). Of the PCI patients 22.9% agreed they were 'fixed for life' and a lower IP score was found to predict this opinion (P = 0.032).

CONCLUSION

PCI patients, particularly pPCI patients, perceive their coronary disease to be relatively benign. Further research is required to investigate if this predicts poor attendance at CR.

Impact of chronic kidney disease on illness perceptions, coping, self-efficacy, psychological distress and quality of life

Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.

Key elements of an evidence-based clinical psychology service within adult critical care

The COVID-19 pandemic has generated renewed interest in the psychological rehabilitation needs of patients admitted to intensive care units. While the availability of embedded practitioner psychologists within adult critical care teams remains inconsistent, post numbers have increased in response to the clinical needs of the pandemic. As psychology services within adult critical care become more widely established, models for service provision will be required. We describe our experience of developing a model for the delivery of a clinical psychology service within critical care in a District General Hospital with specialist tertiary surgical and cancer services. The current paper describes a service design that is firmly rooted in psychological theory and the broader clinical health psychology evidence base. We hope that our learning will be helpful to others.

Social Isolation and Social Support Influence Health Service Utilisation and Survival after a Cardiovascular Disease Event: A Systematic Review

Both cardiovascular disease (CVD) and social health carry high health and economic burdens. We undertook a systematic review to investigate the association between social isolation, low social support, and loneliness with health service utilisation and survival after a CVD event among people living in Australia and New Zealand. Four electronic databases were systematically searched for the period before June 2020. Two reviewers undertook the title/abstract screen. One reviewer undertook a full-text screen and data extraction. A second author checked data extraction. Of 756 records, 25 papers met our inclusion criteria. Included studies recruited 10-12,821 participants, aged 18-98 years, and the majority were males. Greater social support was consistently associated with better outcomes on four of the five themes (discharge destination, outpatient rehabilitation attendance, rehospitalisation and survival outcomes; no papers assessed the length of inpatient stay). Positive social health was consistently associated with better discharge designation to higher independent living. As partner status and living status did not align with social isolation and social support findings in this review, we recommend they not be used as social health proxies. Our systematic review demonstrates that social health is considered in cardiac care decisions and plays a role in how healthcare is being delivered (i.e., outpatient, rehabilitation, or nursing home). This likely contributes to our finding that lower social support is associated with high-intensity healthcare services, lower outpatient rehabilitation attendance, greater rehospitalisation and poorer survival. Given our evidence, the first step to improve cardiac outcomes is acknowledging that social health is part of the decision-making process. Incorporating a formal assessment of social support into healthcare management plans will likely improve cardiac outcomes and survival. Further research is required to assess if support person/s need to engage in the risk reduction behaviours themselves for outpatient rehabilitation to be effective. Further synthesis of the impact of social isolation and loneliness on health service utilisation and survival after a CVD event is required.

Pre-existing anxiety and depression disorders and return to work after musculoskeletal strain or sprain: a phased-based approach

PURPOSE

To examine the impact of pre-existing anxiety and depression disorders on return to work (RTW) using a phase-based approach.

METHODS

Accepted lost-time workers' compensation claims for upper limb or spine strain or sprain from 2009 to 2013 were extracted for workers in the Canadian province of British Columbia (n = 78,186). Pre-existing anxiety and depression disorders were identified using health claims data. Probability of RTW following a first or second work lost-time episode was analyzed using Prentice, Williams and Peterson models for recurrent events (common hazards ratios (cHR)). Probability of a first lost-time recurrence was analyzed using Cox models (HR). All models included two years of follow up and were stratified by gender.

RESULTS

For men, anxiety alone (cHR = 0.90, 95% CI: 0.85 to 0.94) or comorbid with depression (cHR = 0.95, 95% CI: 0.92 to 0.99) was significantly associated with a lower probability of RTW, and comorbid anxiety and depression with a higher probability of recurrence (HR = 1.29, 95% CI: 1.13 to 1.48). In women, comorbid anxiety and depression was significantly associated with a lower probability of RTW (cHR = 0.96, 95% CI: 0.93 to 0.99) and a higher probability of recurrence (HR = 1.15, 95% CI: 1.04 to 1.28); and anxiety alone with a higher probability of recurrence (HR = 1.25, 95% CI: 1.09 to 1.43). There was little evidence that depression alone was associated with RTW or recurrence.

CONCLUSIONS

Workers with a pre-existing anxiety disorder may require additional supports both during lost-time and after initial RTW.

Association between cognitive representation of illness and the outcome of patients with premature coronary artery disease

OBJECTIVE

To assess whether illness perception (IP) in overall and each of its three dimensions (cognitive, emotional and comprehension) have an independent prognostic value in men and women with premature coronary artery disease (CAD).

METHODS

In a prospective cohort, 778 patients (370 men and 408 women) with premature CAD(diagnosed in men aged<45 y and women aged<55 y), who had completed brief illness perception questionnaire were followed up for 4 years. Outcome event was defined as composite of all-cause mortality, nonfatal myocardial infarction(MI), repeated revascularization or/and stroke. Analysis was performed for men and women separately. High scores for each item of illness perception indicate positive perception.

RESULTS

Among men, 90 patients (24.3%) experienced events: 14(3.8%) death, 23(6.2%) nonfatal MI, 9(2.4%) strokes, and 44(11.9%) revascularization. Men with and without event showed no difference regarding the traditional risk factors, depression and anxiety symptoms. Among women, 72(17.6%) had events: 11(2.7%) death, 23(5.6%) nonfatal MI, 7(1.7%) strokes and 31(7.6%) revascularization; who had a lower education, more severe CAD, and more depressive symptoms. After adjustments for potential confounders, overall IP and only its cognitive dimension were significantly associated with the outcome in women:1-score increase in the women's cognitive perception resulted in an 18% decrease in the event (HR = 0.82, 95% CI:0.72 to 0.95; P = 0.007). In the men, this effect remained nonsignificant either for IP or its dimensions.

CONCLUSIONS

Positive cognitive representation of illness was predictive of a decreased likelihood of mortality and/or cardiovascular events in women with premature CAD. Interventional studies are needed to confirm the results.

Prevalence and determinants of return to work after various coronary events: meta-analysis of prospective studies

Return to work (RTW) after a coronary event remains a major concern. This systematic review and meta-analysis of prospective studies published between January 1988 and August 2020, aim to evaluate the prevalence of RTW after a coronary event (myocardial infarction, acute coronary syndrome, angina pectoris) and to assess the determinants of RTW (such as follow-up duration, date of recruitment, country, gender, occupational factors, etc.). PRISMA and MOOSE guidelines were followed. Study quality was assessed using the Newcastle–Ottawa Scale. Random-effects models were carried out to determine pooled prevalence estimates and 95% confident interval. A total of 43 prospective studies (34,964 patients) were investigated. RTW overall random effects pooled prevalence was estimated at 81.1% [95% CI 75.8–85.8]. Country, year of implementation or gender did not significantly modify the prevalence estimates. Lower level of education and degraded left ventricular ejection fraction decreased RTW prevalence estimates (respectively, 76.1% vs 85.6% and 65.3% vs 77.8%). RTW prevalence estimates were higher for white-collars (81.2% vs 65.0% for blue-collars) and people with low physical workload (78.3% vs 64.1% for elevated physical workload).Occupational physical constraints seem to have a negative role in RTW while psycho-logical factors at work are insufficiently investigated. A better understanding of the real-life working conditions influencing RTW would be useful to maintain coronary patients in the labor market.

Baseline depressive symptoms, personal control, and concern moderate the effects of preoperative psychological interventions: the randomized controlled PSY-HEART trial

This study examined whether baseline (3–14 days pre-surgery) levels of (i) depressive or (ii) anxiety symptoms and (iii) illness beliefs moderate the effects of additional preoperative interventions before coronary artery bypass graft surgery on (i) depressive or (ii) anxiety symptoms and (iii) illness beliefs 1 day before surgery, 1 week and 6 months after surgery. In the PSY-HEART trial, 115 patients were assessed. They were randomized into one of three groups: 1. receiving standard medical care only (SMC), additional psychological interventions: 2. aiming to optimize patients’ expectations (EXPECT), or 3. focusing on emotional support. Patients with a higher baseline level of depressive symptoms receiving a preoperative psychological intervention indicated lower depressive symptoms 6 months after surgery compared to SMC. EXPECT increased personal control and concern levels in patients with low baseline personal control/concern 1 day before surgery. Brief preoperative psychological interventions can improve psychological outcomes in heart surgery patients. Baseline status may moderate these effects. The study has been approved by the medical ethics committee of the Philipps University of Marburg and has been pre-registered at www.clinicaltrials.gov (NCT01407055) on August 1, 2011.

A Qualitative Study on the Experiences of Women With Breast Implant Illness

BACKGROUND

Breast implant illness (BII) is a term used to describe physical and psychological symptoms experienced by some women following breast implant surgery. Few studies have examined the experiences of women with BII-a poorly understood condition with no clear cause or treatment.

OBJECTIVES

The aim of this study was to explore women's experiences of BII, including symptoms, healthcare encounters, social media, and explant surgery.

METHODS

Employing an exploratory qualitative methodology, researchers undertook semistructured interviews with 29 women who self-identified as having BII. Interviews were audio-recorded and transcribed verbatim. Data were analyzed by inductive thematic analysis.

RESULTS

Thematic analysis of the interviews identified 6 themes: (1) symptoms without explanation; (2) invalidation and invisibility; (3) making the BII connection; (4) implant toxicity; (5) explant surgery: solution to suffering?; and (6) concealed information. BII was described as distressing and debilitating across multiple domains including relationships, work, identity, and physical and mental health, and symptoms were attributed to implant toxicity and immune system rejection of foreign objects. When their experience was not validated by healthcare professionals, many looked to social media for information, support, and understanding, and saw explant as their only chance of recovery.

CONCLUSIONS

BII is disabling mentally and physically. Women with BII require support, understanding, and validation, and proactive treatment to prevent disability. With unclear pathophysiology, future research should examine how biopsychosocial approaches can be used to guide treatment, and how to best support women with BII, focusing on early detection and evidence-based education and intervention.

Role of illness perception in explanation of severity of post-traumatic stress disorder symptoms after cardiovascular problems

BACKGROUND

Given the role of post-traumatic stress disorder (PTSD) in morbidity and mortality of cardiac patients, the present study was conducted to determine the relationship between the perception of heart disease and severity of PTSD symptoms.

METHODS

Sampled using simple random sampling, 202 cardiovascular patients (50.5% women) were selected and included in this cross-sectional study. The patients admitted to a hospital from January to May 2017 in western Iran were selected and asked to complete the self-report demographic and cardiac risk factors inventory, Brief Illness Perception Questionnaire (Brief-IPQ), and National Stressful Events Survey PTSD Short Scale (NSESSS) checklist. The results were analyzed using the Pearson correlation coefficient and multiple regression analysis.

RESULTS

The mean age of patients was 53.5 ± 11.9 years. The results of the correlation coefficient showed a significant relationship between all the components of illness perception, except personal and treatment control, with PTSD (P < 0.05). The regression model could predict 22.5% of PTSD variance and the greatest role was for the emotional representation (P = 0.002) and female sex (P = 0.008).

CONCLUSION

The perception of cardiovascular patients of the cognitive and emotional components of the disease, especially in women, plays a significant role in experiencing the symptoms of PTSD. Thus, health professionals have to monitor all these components, especially the patient's perceptions and emotional reactions, and to come up with proper and timely interventions for patients at risk to control the adverse effects of PTSD after cardiovascular events.

What an Interventionalist Needs to Know About INOCA

Ischaemia with non-obstructed coronary artery disease (INOCA) remains a diagnostic and therapeutic challenge. An anatomical investigationbased approach to ischaemic heart disease fails to account for disorders of vasomotion. The main INOCA endotypes are microvascular angina, vasospastic angina, mixed (both) or non-cardiac symptoms. The interventional diagnostic procedure (IDP) enables differentiation between clinical endotypes, with linked stratified medical therapy leading to a reduced symptom burden and a better quality of life. Interventionists are therefore well placed to make a positive impact with more personalised care. Despite adjunctive tests of coronary function being supported by contemporary guidelines, IDP use in daily practice remains limited. More widespread adoption should be encouraged. This article reviews a stratified approach to INOCA, describes a streamlined approach to the IDP and highlights some practical and safety considerations.

Perception of Illness and Its Association with Treatment Willingness in Patients with Newly Diagnosed Nonalcoholic Fatty Liver Disease

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease of immense public health relevance. Understanding illness perceptions in the NAFLD population will provide sound scientific evidence for planning high-quality patient-centered care and implementing effective interventions. The Brief Illness Perception Questionnaire (BIPQ) is a robust psychometric tool to systematically assess the dimensions of illness perceptions in various chronic ailments.

METHODS

In a cross-sectional study enrolling patients with newly diagnosed NAFLD, the sociodemographic, anthropometric, biochemical, and radiological determinants of enhanced illness perceptions (measured by the BIPQ score) were investigated using univariate and multivariable binary logistic regression analyses. Finally, the association between individual domains of the BIPQ and willingness to participate in comprehensive medical management was explored.

RESULTS

In total, 264 patients (mean age 53 ± 11.9 years, 59.8% males) were enrolled in the final analysis. The mean and median BIPQ scores in the study population were 30.3 ± 12.8 and 31.0 (IQR, 22.0-40.0), respectively. The variables having a significant independent association with heightened perceptions (BIPQ > 31) were family history of liver disease (aOR, 5.93; 95% CI, 1.42-24.74), obesity (aOR, 3.33; 95% CI, 1.57-7.05), diabetes mellitus (aOR, 2.35; 95% CI, 1.01-5.49), and transaminitis (aOR, 2.85; 95% CI, 1.42-5.69). Patients with a higher level of illness perceptions (31.6 ± 12.9 vs 27.8 ± 12.3, p = 0.022) were more likely to express a willingness to participate in the comprehensive management plan, with 3 of the 8 domains (consequence, identity, and treatment control) mainly affecting willingness.

CONCLUSION

A family history of liver disease, obesity, diabetes, and transaminitis were independently associated with increased illness perceptions. A belief in serious consequences, a strong illness identity, and higher perceived treatment control were significantly associated with the willingness to undergo comprehensive care for NAFLD.

Prognosis in functional and recognised pathophysiological neurological disorders - a shared basis

OBJECTIVE

To compare self-reported outcomes, clinical trajectory and utility of baseline questionnaire responses in predicting prognosis in functional and recognised pathophysiological neurological disorders.

METHODS

Baseline data on 2581 patients included health-related quality of life, psychological and physical symptoms, illness perceptions, consultation satisfaction and demographics. The prospective cohort included neurology outpatients classified with a functional (reporting symptoms 'not at all' or 'somewhat explained' by 'organic disease'; n = 716) or recognised pathophysiological disorder ('largely' or 'completely explained'; n = 1865). Logistic regression and deep neural network models were used to predict self-reported global clinical improvement (CGI) at 12-months.

RESULTS

Patients with functional and recognised pathophysiological disorders reported near identical outcomes at 12-months with 67% and 66% respectively reporting unchanged or worse CGI. In multivariable modelling 'negative expectation of recovery' and 'disagreement with psychological attribution' predicted same or worse outcome in both groups. Receipt of disability-related state benefit predicted same or worse CGI outcome in the functional disorder group only (OR = 2.28 (95%-CI: 1.36-3.84) in a group-stratified model) and was not related to a measure of economic deprivation. Deep neural network models trained on all 92 baseline features predicted poor outcome with area under the receiver-operator curve of 0.67 in both groups.

CONCLUSIONS

Those with functional and recognised pathophysiological neurological disorder share similar outcomes, clinical trajectories, and poor prognostic markers in multivariable models. Prediction of outcome at a patient level was not possible using the baseline data in this study.

Systemic and Local Cytokines Profile Determine Severity and Prognosis in Human Septic Arthritis: A Pilot Study

BACKGROUND

Septic arthritis (SA) is a medical emergency. The most common etiological agents are bacteria, which activate the local immune response coordinated by cytokines; however, little is known about the cytokine profile in human SA.

AIM

To determine the association of local and systemic cytokine profiles with the severity and prognosis of patients with SA.

METHODS

Patients with clinical and laboratory diagnosed SA were enrolled as well as a control group. Serum and synovial fluid (SF) samples were obtained for determining cytokines and glucose levels; SF samples were used for histological analysis. Osteochondral damage and general health status and quality of life (SF-36) were evaluated during recruitment day. WOMAC osteoarthritis index score and SF-36 questionnaire were used a year after recruitment day as a follow up.

RESULTS

A systemic and local proinflammatory cytokine profile was found in patients compared to the control group (p <0.05). IL-6 was 28 and 525 times higher than controls in sera and SF, respectively (p <0.0001). Systemic IL-6 correlated negatively with general mental health score (p = 0.0184) and was associated with a higher osteoarthritis index after one year follow-up in the patients (p = 0.0352). HMGB1 in SF was found higher in patients with SA (p <0.0001), and it was associated with osteochondral damage (p = 0.0042). TNF-α in SF correlated negatively with SF-36 questionnaire one year after patients' recruitment in role limitation score (p = 0.0318), body pain score (p = 0.0315), and general mental health score (p = 0.0197).

CONCLUSION

Serum and SF cytokine signatures are associated with disease severity and prognosis in patients with SA.

The association of cognitive representations with psychological adjustment in experience of infertility and fertility treatment: A systematic review

INTRODUCTION

The aim of this systematic review was to examine studies describing the association of cognitive representations with psychological adjustment or maladjustment during the experience of infertility and its treatment in light of the Common-Sense Model. According to this theoretical model cognitive perceptions about an illness can be associated with emotional adaptation.

METHODS

A systematic search of four electronic databases (PubMed, APA PsycINFO, SCOPUS, ScienceDirect) was performed. This review considered only quantitative, primary studies in the English language without geographical limitations, published during the period 1996–2020 and relevant to the objective. The population of interest was infertile individuals who are having or not having infertility treatment. Only studies that examined the association between independent variables, such as perceived causes, timeline, controllability, consequences, symptoms, illness coherence and emotional representations, with psychological variables, such as anxiety, worry, distress, depression and well-being, were included. Two authors performed an independent extraction of articles using predefined data fields. Relevant articles were critically appraised and a narrative synthesis was conducted.

RESULTS

Seven cross-sectional studies met the inclusion and methodological criteria and were included in the review. The review results revealed that all components of cognitive representations of infertility and its treatment may correlate with psychological adaptation of people who deal with a fertility problem, at intrapersonal and interpersonal level.

CONCLUSIONS

This systematic review suggested that the Common-Sense Model is an appropriate theoretical model to be applied in the experience of infertility and health professionals can make interventions based on modifying cognitive perceptions of a fertility problem that may increase levels of psychological well-being and decrease levels of distress.

Delivering an efficient and effective support group for patients with implantable cardioverter-defibrillators (ICDs): patient perspectives of key concerns and predictors of inclination to attend

BACKGROUND

A subset of patients experience psychological distress following insertion of an implantable cardioverter-defibrillator (ICD) and ICD support groups are recommended, however access to these groups is limited. This study aimed: to gauge a better understanding of patients' key ICD-related concerns; to determine patient interest in a support group and topics deemed helpful to address in a support group; and to examine factors which affect patient inclination to attend.

METHODS

One hundred and thirty nine patients completed the ICD Patient Concerns Questionnaire - Brief (ICDC-B) and a semi-structured survey. Non-parametric tests were used to examine associations and differences in the quantitative data. Qualitative data were analysed using thematic analysis.

RESULTS

42% of respondents said they would attend a support group and inclination to attend was associated with higher ICD concerns and a shorter time since implant. Topics considered important to address in a group were information about heart conditions and devices, the impact of an ICD on daily life and coping with fear of shocks.

CONCLUSION

We concluded that there is interest in further support amongst many patients and that ICD support groups may be delivered efficiently by targeting patients who have higher levels of ICD concerns and within the first few years after implant.

Prevalence and influencing factors of chronic post-traumatic stress disorder in patients with myocardial infarction, transient ischemic attack (TIA) and stroke - an exploratory, descriptive study

BACKGROUND

Cardio- and cerebrovascular events such as myocardial infarction (MI), stroke and transient ischemic attack (TIA) are leading causes of death and disability and have also been associated with poor mental outcomes. In addition, cardio- and cerebrovascular events may pose the risk of experiencing a sudden traumatic occurrence of symptoms during ictus and thus contribute to high rates of PTSD as well as high rates of subsequent depression and anxiety. Moreover, MI, TIA and stroke survivors with PTSD, depressive and anxiety symptoms may have poorer health-related quality of life (HRQoL) and poorer disease prognosis than patients who do not develop psychiatric symptoms after ictus. However, data on the prevalence of PTSD, anxiety and depression, as well as the HRQoL, coping strategies and potential risk factors for development of PTSD in these patients, are rare.

METHODS

In an exploratory, descriptive study we interviewed 112 patients (54 MI, 18 TIA, 40 stroke; mean age: 69.5 years, 55.4% males) from three general physician practices and used psychometric self-assessment tools to determine the occurrence of PTSD and psychosomatic comorbidity, anxiety and depression and to assess HRQoL and coping strategies. We evaluated disease severity and compared the patient groups to each other. Moreover, we assessed psychological outcome differences between patients with or without PTSD after ictus.

RESULTS

The prevalence of PTSD after MI, TIA and stroke was 23.2%. The patients who developed PTSD had higher rates of depression, anxiety and maladaptive coping as well as reduced HRQoL. Adaptive coping was positively related to better mental HRQoL and negatively related to anxiety and depression. Disease severity of MI, TIA and stroke was not related to PTSD, depression, anxiety or physical HRQoL.

CONCLUSIONS

Experiencing MI, TIA or stroke means confronting a life-threatening event for those affected and, therefore, these can be regarded as traumatic events. Cerebral and cardiovascular events increase the risk of developing chronic PTSD with subsequent increased depression and anxiety and reduced HRQoL. These findings emphasize the need for early screening and diagnosis of PTSD in somatically ill patients, which should be followed by specialized treatment, as PTSD hampers overall (somatic) disease prognosis.

Impact of anxiety and depression disorders on sustained return to work after work-related musculoskeletal strain or sprain: a gender stratified cohort study

Objective:

The aim of this study was to examine the impact of anxiety and depression disorders on sustained return to work (RTW) for men and women with musculoskeletal strain or sprain.

Methods:

Accepted lost-time claims for spine and upper-extremity strain or sprain were extracted for workers in the Canadian province of British Columbia from 2009 to 2013 (N=84 925). Pre-existing and new onset anxiety and depression disorders were identified using longitudinal health claims data. Probability of sustained RTW was analyzed using Cox proportional hazards models, stratified by gender and adjusted for potential confounders.

Results:

For pre-existing disorders, compared to men with no anxiety and no depression, men with anxiety only [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.84–0.93], depression only (HR 0.94, 95% CI 0.89–1.00), and anxiety and depression (HR 0.93, 95% CI 0.90–0.97) had lower probabilities of sustained RTW in adjusted models. The same direction of effect was found for women, but anxiety only had a smaller effect size among women compared to men (HR anxiety only 0.95, 95% CI 0.92–0.99; HR depression only 0.98, 95% CI 0.93–1.03, HR anxiety and depression 0.94, 95% CI 0.91–0.97). Among men and women, new onset disorders were associated with lower probability of sustained RTW and the effect estimates were larger than for pre-existing disorders.

Conclusions:

Findings suggest that workers’ compensation benefits and programs intended to improve RTW after musculoskeletal injury should take pre-existing and new onset anxiety and depression disorders into consideration and that gender-sensitive work disability strategies may be warranted.

Understanding Persons With Disabilities’ Reasons for Not Seeking Employment

Unemployment is common for persons with disabilities but little is known about the different reasons why people with disabilities may not be seeking employment. This study identified the reasons that people living with disabilities report for not seeking employment, from the 2015 Kessler Foundation National Employment and Disability Survey (KFNEDS) and variation of reasons by demographic, socioeconomic, and disability characteristics. We conducted a content analysis of responses to an open-ended question on the KFNEDS. The analytic sample ( n = 1,254) included adults (ages 18–64) living with disabilities, who self-identified as either unemployed or not seeking employment. Team coding used a hybrid inductive/deductive approach to identify nine meaningful reasons why people with disabilities may not seek employment. Overall, medical conditions, functional limitations, or their disability were more likely to be reported as reasons for not seeking work, rather than situational reasons associated with workplace engagement, such as “lack of job opportunities.” Bivariate comparisons of codes across demographic, socioeconomic, and disability characteristics noted variability in reasons reported by respondents by sex, race/ethnicity, age, household income, and disability. These findings provide an understanding of diverse reasons for not seeking employment, which can inform programs and policies that promote labor force participation of people with disabilities.

The Illness Belief Network Questionnaire: Development and Evaluation of a Psychosomatic Assessment Tool

Objective: Patients’ beliefs and emotions toward an illness can influence their coping responses, illness behaviors, adherence to treatment, quality of life, and even the psychoneuroimmune responses. The aim of present study was to develop and validate a novel questionnaire assessing both rational and irrational beliefs of patients regarding their illness.

Method: In a cross sectional methodological study, the items of the Illness Belief Network (IBN) were developed regarding patients and clients’ opinions about and attribution of their disease extracted from 400 clinical interviews and were coded based on Leventhal’s self-regulation model. An expert panel coded the items. A total of 400 patients with different medical conditions completed the questionnaire. Participants additionally rated the Illness Perceptions Questionnaire in its revised form (IPQ-R) to assess convergent validity. Construct validity was examined by conducting exploratory and confirmatory factor analysis. The Cronbach alpha and Intracluster Correlation Coefficient (ICC) were used for examining Internal consistency and test-retest reliability of the IBN.

Results: The IBN questionnaire was finalized with 84 items, and the results of factor analysis revealed 5 factors: psychosocial causes, environmental causes, control, meaning, and consequence/timeline; extracted factors were confirmed by confirmatory factor analysis. Cronbach’s α coefficient for scale was 0.92 and it ranged from 0.79 to 0.89 for the subscales. IBN indicated excellent test-retest reliability results based on ICC 0.842(95%CI: 0.798-0.846). The correlation coefficients of all items exceeded the prespecified acceptable value of 0.40, indicating satisfactory item discriminant validity, and correlation between IBN and IPQ-R subscales were statistically significant (all p values < 0.01), indicating acceptable convergent validity.

Conclusion: The IBN questionnaire is a valid and reliable phenomenological, non-judging, and clinical tool to assess patient’s rational and irrational or faith-based beliefs about the illness. This tool can be used to improve doctor-patient communication by exploring the complex nature of human thinking.

Self-reported health without clinically measurable benefits among adult users of multivitamin and multimineral supplements: a cross-sectional study

OBJECTIVE

Multiple clinical trials fail to identify clinically measurable health benefits of daily multivitamin and multimineral (MVM) consumption in the general adult population. Understanding the determinants of widespread use of MVMs may guide efforts to better educate the public about effective nutritional practices. The objective of this study was to compare self-reported and clinically measurable health outcomes among MVM users and non-users in a large, nationally representative adult civilian non-institutionalised population in the USA surveyed on the use of complementary health practices.

DESIGN

Cross-sectional analysis of the effect of MVM consumption on self-reported overall health and clinically measurable health outcomes.

PARTICIPANTS

Adult MVM users and non-users from the 2012 National Health Interview Survey (n=21 603).

PRIMARY AND SECONDARY OUTCOME MEASURES

Five psychological, physical, and functional health outcomes: (1) self-rated health status, (2) needing help with routine needs, (3) history of 10 chronic diseases, (4) presence of 19 health conditions in the past 12 months, and (5) Kessler 6-Item (K6) Psychological Distress Scale to measure non-specific psychological distress in the past month.

RESULTS

Among 4933 adult MVM users and 16 670 adult non-users, MVM users self-reported 30% better overall health than non-users (adjusted OR 1.31; 95% CI 1.17 to 1.46; false discovery rate adjusted p<0.001). There were no differences between MVM users and non-users in history of 10 chronic diseases, number of present health conditions, severity of current psychological distress on the K6 Scale and rates of needing help with daily activities. No effect modification was observed after stratification by sex, education, and race.

CONCLUSIONS

MVM users self-reported better overall health despite no apparent differences in clinically measurable health outcomes. These results suggest that widespread use of multivitamins in adults may be a result of individuals' positive expectation that multivitamin use leads to better health outcomes or a self-selection bias in which MVM users intrinsically harbour more positive views regarding their health.

Factors Predicting the Utilization of Center-Based Cardiac Rehabilitation Program

Although cardiac rehabilitation (CR) is clearly beneficial to improving patients’ physical functioning and reducing heart disease progression, significant proportions of patients do not complete CR programs. To evaluate the prevalence and predictors of completion of a center-based CR program in eligible cardiac patients, existing data collected from electronic medical records were used. To identify the predictors of CR completion, we used principal components analysis (PCA) and an artificial neural network (ANN) module. Among 685 patients, 61.4% (n = 421) completed the program, 31.7% (n = 217) dropped out, and 6.9% (n = 47) were referred but failed to initiate the program. PCA was conducted to consolidate baseline data into three factors—(1) psychosocial factors (depression, anxiety, and quality of life), (2) age, and (3) BMI, which explained 66.8% of the total variance. The ANN model produced similar results as the PCA. Patients who completed CR sessions had greater extremity strength and flexibility, longer six-minute walk distance, more CR knowledge, and a better quality of life. The present study demonstrated that patients who were older, obese, and who had depression, anxiety, or a low quality of life were less likely to complete the CR program.

When Beliefs Face Reality: An Integrative Review of Belief Updating in Mental Health and Illness

Belief updating is a relatively nascent field of research that examines how people adjust their beliefs in light of new evidence. So far, belief updating has been investigated in partly unrelated lines of research from different psychological disciplines. In this article, we aim to integrate these disparate lines of research. After presenting some prominent theoretical frameworks and experimental designs that have been used for the study of belief updating, we review how healthy people and people with mental disorders update their beliefs after receiving new information that supports or challenges their views. Available evidence suggests that both healthy people and people with particular mental disorders are prone to certain biases when updating their beliefs, although the nature of the respective biases varies considerably and depends on several factors. Anomalies in belief updating are discussed in terms of both new insights into the psychopathology of various mental disorders and societal implications, such as irreconcilable political and societal controversies due to the failure to take information into account that disconfirms one’s own view. We conclude by proposing a novel integrative model of belief updating and derive directions for future research.

Predicting Lipid-Lowering Medication Persistence after the First Cardiovascular Disease Hospitalization

Objectives This study analyzed patient factors in medication persistence after discharge from the first hospitalization for cardiovascular disease (CVD) with the aim of predicting persistence to lipid-lowering therapy for 1 to 2 years.

Methods A subcohort having a first CVD hospitalization was selected from 313,207 patients for proportional hazard model analysis. Logistic regression, support vector machine, artificial neural networks, and boosted regression tree (BRT) models were used to predict 1- and 2-year medication persistence.

Results Proportional hazard modeling found significant association of persistence with age, diabetes history, complication and comorbidity level, days stayed in hospital, CVD diagnosis type, in-patient procedures, and being new to therapy. BRT had the best predictive performance with c-statistic of 0.811 (0.799–0.824) for 1-year and 0.793 (0.772–0.814) for 2-year prediction using variables potentially available shortly after discharge.

Conclusion The results suggest that development of a machine learning-based clinical decision support tool to focus improvements in secondary prevention of CVD is feasible.

Illness Perception After Heart Valve Surgery: Differences Among Men and Women

BACKGROUND

Illness perception is composed of thoughts, ideas, and beliefs about illness, and a negative illness perception is known to be associated with poor outcomes. Among men and women, clinical outcomes after heart valve surgery are known to differ, but knowledge about differences in illness perception is sparse.

OBJECTIVES

The aim of this study is to describe the differences in illness perception among men and women after open heart valve surgery and to identify sociodemographic and clinical characteristics associated with worse illness perception in men and women.

METHODS

In a national cross-sectional study combined with register-based clinical and sociodemographic information, data on illness perception were collected with the Brief Illness Perception Questionnaire. Worse illness perception was defined as the worst quartile of each item of the Brief Illness Perception Questionnaire. Multiple logistic regression analyses were conducted to explore characteristics associated with worse illness perception.

RESULTS

Of 1084 eligible patients, 32% (n = 349) completed the questionnaire (67% men; mean age, 68 years). Compared with men, women reported significantly worse scores of illness perception in 6 of 8 items. Furthermore, being female, age, length of stay, and comorbidity were associated with worse illness perception (worse quartile of scores). Age, higher educational level, and comorbidity were found to be associated with worse illness perception for men and length of stay for women.

CONCLUSION

After open heart valve surgery, illness perception differs among men and women, with women having worse illness perception. Among the total population, being female, age, a longer length of stay, and comorbidity were also associated with worse illness perception.

Trajectories of Current and Predicted Satisfaction With One's Life Following a Cancer Diagnosis

Background

Poor physical and mental health is common among cancer survivors, but little is known about how cancer influences life satisfaction and expectations about one's future, both of which may subsequently influence health decisions and outcomes.

Purpose

The current study examined how a cancer diagnosis influences current and predicted future life satisfaction in seven domains, including family, finances, work, and health.

Methods

We leveraged data from three waves of the Midlife in the United States study (N = 6,389) and examined the relation between new and past cancer diagnoses on satisfaction using generalized estimating equations. We also compared participants' predicted satisfaction to the actual satisfaction they reported at later waves of data collection, and examined whether concordance between the two differed by cancer history.

Results

A cancer diagnosis was associated with a decline in satisfaction about one's present health and sex life, ps < .05, but satisfaction with all other domains remained steady or improved. In contrast, predictions about the future became and remained less optimistic than the predictions of those without cancer across all life domains except relationships with children, ps < .05. Within-subjects comparisons of predicted and actual satisfaction suggest those without a cancer history were optimistic in their predictions across all life domains except health whereas survivors were more accurate in their predictions.

Conclusions

Given the many ways in which expectations about the future can influence decision making, behavior, and health, survivors' attenuated optimistic outlooks may influence their health and well-being.

Factors related to poor adherence in Latvian asthma patients

Background

The problem of nonadherence to therapy is a key reason of insufficient asthma control. Evaluating the beliefs about asthma medication, cognitive and emotional perceptions may help to identify patients with poor adherence to treatment in clinical practice which need additional attention in order to increase the likelihood of them taking their asthma medication according to the prescribed treatment protocol. The purpose of this study is to assess whether beliefs about asthma medication, cognitive and emotional factors are related to poor treatment adherence of asthma medication in a sample of asthma patients in Latvia.

Methods

Study subjects were asthma patients attending outpatient pulmonologist consultations in Latvia during September 2013 to December 2015. Beliefs about asthma medicine, cognitive and emotional factors related to asthma were determined in a cross-sectional, self-administered survey. The validated Beliefs about Medicines Questionnaire (BMQ) and the Brief Illness Perception Questionnaire (brief IPQ) were used. Treatment adherence was assessed using 5-item version of the Medication Adherence Reporting Scale (MARS). The total sample size was 352 patients. Logistic regression models were used to predict poor adherence to asthma treatment. The validity of each logistic regression model was assessed by the Hosmer/Lemeshow test. The main outcome measure was self-reported adherence to treatment.

Results

The more the patients agreed with the statement “My future health depends on my asthma medication” the lower the possibility of poor adherence to asthma treatment (OR 0.42; 95% CI 0.24–0.74). The more concerned the patients were in regard to long-term effects of their medication (OR 2; 95% CI 1.22–3.27), the higher the probability of poor treatment adherence.

Conclusions

Screening asthma patients using the BMQ may help to identify those to benefit from interventions targeting their concerns and medication beliefs in order to improve adherence to asthma medication.

1-Year Outcomes of Angina Management Guided by Invasive Coronary Function Testing (CorMicA)

Objectives

The aim of this study was to test the hypothesis that invasive coronary function testing at time of angiography could help stratify management of angina patients without obstructive coronary artery disease.

Background

Medical therapy for angina guided by invasive coronary vascular function testing holds promise, but the longer-term effects on quality of life and clinical events are unknown among patients without obstructive disease.

Methods

A total of 151 patients with angina with symptoms and/or signs of ischemia and no obstructive coronary artery disease were randomized to stratified medical therapy guided by an interventional diagnostic procedure versus standard care (control group with blinded interventional diagnostic procedure results). The interventional diagnostic procedure–facilitated diagnosis (microvascular angina, vasospastic angina, both, or neither) was linked to guideline-based management. Pre-specified endpoints included 1-year patient-reported outcome measures (Seattle Angina Questionnaire, quality of life [EQ-5D]) and major adverse cardiac events (all-cause mortality, myocardial infarction, unstable angina hospitalization or revascularization, heart failure hospitalization, and cerebrovascular event) at subsequent follow-up.

Results

Between November 2016 and December 2017, 151 patients with ischemia and no obstructive coronary artery disease were randomized (n = 75 to the intervention group, n = 76 to the control group). At 1 year, overall angina (Seattle Angina Questionnaire summary score) improved in the intervention group by 27% (difference 13.6 units; 95% confidence interval: 7.3 to 19.9; p < 0.001). Quality of life (EQ-5D index) improved in the intervention group relative to the control group (mean difference 0.11 units [18%]; 95% confidence interval: 0.03 to 0.19; p = 0.010). After a median follow-up duration of 19 months (interquartile range: 16 to 22 months), major adverse cardiac events were similar between the groups, occurring in 9 subjects (12%) in the intervention group and 8 (11%) in the control group (p = 0.803).

Conclusions

Stratified medical therapy in patients with ischemia and no obstructive coronary artery disease leads to marked and sustained angina improvement and better quality of life at 1 year following invasive coronary angiography. (Coronary Microvascular Angina [CorMicA]; NCT03193294)

Association between illness perception and health-related quality of life in patients with preexisting premature coronary artery disease

OBJECTIVES

Illness perception in younger age differs from that in older age. We aimed to examine the association between illness perception and health-related quality of life (HRQoL) in patients with premature coronary artery disease (CAD).

METHODS

In a cross-sectional design, between November 2016 and September 2017, a total of 779 adults (52.5% female) with premature CAD (diagnosed in men aged ≤ 45 y and women aged ≤ 55 y) completed the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Brief Illness Perception, and the Short-Form Health Survey 36 questionnaires in an outpatient clinic 8 years after the diagnosis.

RESULTS

The patients were treated with coronary artery bypass graft surgery (24.6%), percutaneous coronary intervention (39.5%), and medical treatment (35.8%). The cognitive, emotional, and comprehension aspects of illness perception had significant associations with both physical and mental health in univariable analysis (all Ps < 0.001). After adjustments for potential confounding factors, higher cognitive perception was independently associated with greater physical health [OR = 4.13, Confidence interval (CI): 3.53-4.72] and mental health (OR = 3.17, CI: 2.57-3.77). Additionally, emotional perception was also directly associated with higher physical (OR = 1.62, CI: 1.17-2.06) and mental (OR = 1.52, CI: 1.07-1.96) health; all Ps < 0.001.

CONCLUSIONS

Of the 3 different aspects of illness perception, cognitive perception appeared to have the greatest influence on HRQoL, either physical or mental health. Further studies are needed to investigate whether cognitive interventions can improve HRQoL in premature CAD patients and, thus, their outcome.

Relationship Between Optimism and Outcomes in Patients With Chronic Angina Pectoris

Greater optimism regarding recovery from chronic illness is associated with improved quality of life and clinical outcomes. We performed a post-hoc analysis on the association between optimism and outcomes in Ranolazine in Patients with Incomplete Revascularization after Percutaneous Coronary Intervention (RIVER-PCI), a randomized trial in patients with chronic angina pectoris who had incomplete revascularization following percutaneous coronary intervention. At baseline, patients answered how much they agreed with the phrase, "I am optimistic about my future and returning to a normal lifestyle." We evaluated the association between baseline optimism and time to ischemia-driven hospitalization or revascularization using a Cox model, and the association between baseline optimism and change in frequency of angina pectoris using a mixed measures model. Of 2,389 patients, 782 (33.2%) were very optimistic ("strongly agree"), 1,000 (42.4%) were optimistic ("agree"), 451 (19.1%) were neutral ("undecided"), and 123 (5.2%) were not optimistic ("disagree" or "strongly disagree"). Very optimistic patients had a lower prevalence of co-morbidities and less severe angina at baseline than less optimistic patients. The rate of ischemia-driven revascularization or hospitalization was higher in neutral and not optimistic patients compared with very optimistic patients; this finding persisted after adjustment for co-morbidities and baseline angina frequency (hazard ratio 1.42, 95% confidence interval 1.14 to 1.77 for neutral vs very optimistic; hazard ratio 1.38, 95% confidence interval 0.98 to 1.94 for not optimistic vs very optimistic). Neutral and not optimistic patients also had less improvement in angina than very optimistic patients. In conclusion, in patients with angina, those with more self-reported optimism had better health status outcomes. Whether structured interventions targeting optimism improve outcomes in these patients warrants further study.

How to Diagnose and Manage Angina Without Obstructive Coronary Artery Disease: Lessons from the British Heart Foundation CorMicA Trial

Patients with symptoms and/or signs of ischaemia but no obstructive coronary artery disease (INOCA) present a diagnostic and therapeutic challenge. Microvascular and/or vasospastic angina are the two most common causes of INOCA; however, invasive coronary angiography lacks the sensitivity to diagnose these functional coronary disorders. In this article, the authors summarise the rationale for invasive testing in the absence of obstructive coronary disease, namely that correct treatment for angina patients starts with the correct diagnosis. They provide insights from the CORonary MICrovascular Angina (CorMicA) study, where an interventional diagnostic procedure was performed with linked medical therapy to improve patient health. Identification of these distinct disorders (microvascular angina, vasospastic angina or non-cardiac chest pain) is key for stratifying INOCA patients, allowing prognostic insights and better patient care with linked therapy based on contemporary guidelines. Finally, they propose a framework to diagnose and manage patients in this common clinical scenario.

Measuring Illness Behavior in One Minute

Abstract. The present study addresses shortcomings in previous psychometric research into the Scale for the Assessment of Illness Behavior (SAIB) and develops a short form, the SAIB-10. We used ant-colony optimization to construct a subset of items in an exploratory sample ( n = 1,187) and affirmed it in factor analysis in a confirmatory sample ( n = 1,208). We find excellent model fit and evidence for strict invariance across sex and age. As expected, there were associations with distressed personality, perceived social support, and mental health. Finally, we report normative values for usage by researchers and clinicians. In sum, the SAIB-10 is an economical measure of illness behavior and recommended as a screening tool or for large-scale surveys.

Interventions to support return to work for people with coronary heart disease

BACKGROUND

People with coronary heart disease (CHD) often require prolonged absences from work to convalesce after acute disease events like myocardial infarctions (MI) or revascularisation procedures such as coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). Reduced functional capacity and anxiety due to CHD may further delay or prevent return to work.

OBJECTIVES

To assess the effects of person- and work-directed interventions aimed at enhancing return to work in patients with coronary heart disease compared to usual care or no intervention.

SEARCH METHODS

We searched the databases CENTRAL, MEDLINE, Embase, PsycINFO, NIOSHTIC, NIOSHTIC-2, HSELINE, CISDOC, and LILACS through 11 October 2018. We also searched the US National Library of Medicine registry, clinicaltrials.gov, to identify ongoing studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) examining return to work among people with CHD who were provided either an intervention or usual care. Selected studies included only people treated for MI or who had undergone either a CABG or PCI. At least 80% of the study population should have been working prior to the CHD and not at the time of the trial, or study authors had to have considered a return-to-work subgroup. We included studies in all languages. Two review authors independently selected the studies and consulted a third review author to resolve disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data and independently assessed the risk of bias. We conducted meta-analyses of rates of return to work and time until return to work. We considered the secondary outcomes, health-related quality of life and adverse events among studies where at least 80% of study participants were eligible to return to work.

MAIN RESULTS

We found 39 RCTs (including one cluster- and four three-armed RCTs). We included the return-to-work results of 34 studies in the meta-analyses.Person-directed, psychological counselling versus usual careWe included 11 studies considering return to work following psychological interventions among a subgroup of 615 participants in the meta-analysis. Most interventions used some form of counselling to address participants' disease-related anxieties and provided information on the causes and course of CHD to dispel misconceptions. We do not know if these interventions increase return to work up to six months (risk ratio (RR) 1.08, 95% confidence interval (CI) 0.84 to 1.40; six studies; very low-certainty evidence) or at six to 12 months (RR 1.24, 95% CI 0.95 to 1.63; seven studies; very low-certainty evidence). We also do not know if psychological interventions shorten the time until return to work. Psychological interventions may have little or no effect on the proportion of participants working between one and five years (RR 1.09, 95% CI 0.88 to 1.34; three studies; low-certainty evidence).Person-directed, work-directed counselling versus usual careFour studies examined work-directed counselling. These counselling interventions included advising patients when to return to work based on treadmill testing or extended counselling to include co-workers' fears and misconceptions regarding CHD. Work-directed counselling may result in little to no difference in the mean difference (MD) in days until return to work (MD -7.52 days, 95% CI -20.07 to 5.03 days; four studies; low-certainty evidence). Work-directed counselling probably results in little to no difference in cardiac deaths (RR 1.00, 95% CI 0.19 to 5.39; two studies; moderate-certainty evidence).Person-directed, physical conditioning interventions versus usual careNine studies examined the impact of exercise programmes. Compared to usual care, we do not know if physical interventions increase return to work up to six months (RR 1.17, 95% CI 0.97 to 1.41; four studies; very low-certainty evidence). Physical conditioning interventions may result in little to no difference in return-to-work rates at six to 12 months (RR 1.09, 95% CI 0.99 to 1.20; five studies; low-certainty evidence), and may also result in little to no difference on the rates of patients working after one year (RR 1.04, 95% CI 0.82 to 1.30; two studies; low-certainty evidence). Physical conditioning interventions may result in little to no difference in the time needed to return to work (MD -7.86 days, 95% CI -29.46 to 13.74 days; four studies; low-certainty evidence). Physical conditioning interventions probably do not increase cardiac death rates (RR 1.00, 95% CI 0.35 to 2.80; two studies; moderate-certainty evidence).Person-directed, combined interventions versus usual careWe included 13 studies considering return to work following combined interventions in the meta-analysis. Combined cardiac rehabilitation programmes may have increased return to work up to six months (RR 1.56, 95% CI 1.23 to 1.98; number needed to treat for an additional beneficial outcome (NNTB) 5; four studies; low-certainty evidence), and may have little to no difference on return-to-work rates at six to 12 months' follow-up (RR 1.06, 95% CI 1.00 to 1.13; 10 studies; low-certainty evidence). We do not know if combined interventions increased the proportions of participants working between one and five years (RR 1.14, 95% CI 0.96 to 1.37; six studies; very low-certainty evidence) or at five years (RR 1.09, 95% CI 0.86 to 1.38; four studies; very low-certainty evidence). Combined interventions probably shortened the time needed until return to work (MD -40.77, 95% CI -67.19 to -14.35; two studies; moderate-certainty evidence). Combining interventions probably results in little to no difference in reinfarctions (RR 0.56, 95% CI 0.23 to 1.40; three studies; moderate-certainty evidence).Work-directed, interventionsWe found no studies exclusively examining strictly work-directed interventions at the workplace.

AUTHORS' CONCLUSIONS

Combined interventions may increase return to work up to six months and probably reduce the time away from work. Otherwise, we found no evidence of either a beneficial or harmful effect of person-directed interventions. The certainty of the evidence for the various interventions and outcomes ranged from very low to moderate. Return to work was typically a secondary outcome of the studies, and as such, the results pertaining to return to work were often poorly reported. Adhering to RCT reporting guidelines could greatly improve the evidence of future research. A research gap exists regarding controlled trials of work-directed interventions, health-related quality of life within the return-to-work process, and adverse effects.

Health belief about adjuvant endocrine therapy in premenopausal breast cancer survivors: a qualitative study

OBJECTIVE

The aim of this study is to describe the connotations of health beliefs about adjuvant endocrine therapy (AET) in premenopausal breast cancer survivors in Northeast China and to explore the reasons underlying bad behaviours and influential factors of AET adherence and persistence.

METHODS

Semi-structured interviews were conducted using a qualitative description research method with 30 premenopausal breast cancer survivors who had undergone surgery and AET for more than half a year. The researcher collected and coded the interview transcripts and extracted the concepts and themes.

RESULTS

Two main categories of themes regarding the health beliefs of survivors who were undergoing AET were formed in the conceptual framework: connotations and modifiable factors. Subcategories of the first category included perceptions of the survivors regarding the risks and effects of recurrence or metastasis of breast cancer; the methods, benefits and barriers of AET; behavioural clues; and self-efficacy. Subcategories of the second category included religious belief, disposition, matrimony and other demographic factors as well as traditional Chinese female characteristics, gender role and other socio-cultural factors.

CONCLUSION

Demographic, socio-cultural and other factors play an important role in the health beliefs of breast cancer survivors. Health beliefs such as related knowledge of AET, related cognition of recurrence or metastasis of breast cancer directly affect adherence to and persistence with AET. Therefore, implementing interventions with respect to health beliefs may enhance adherence to AET.

The Four-Cluster Spectrum of Mind-Body Interrelationships: An Integrative Model

Despite the shift toward a biopsychosocial paradigm of medicine, many physicians and mental health professionals (MHPs) find it difficult to treat patients with psycho-somatic disorders. This situation is particularly troublesome due to the high prevalence of these conditions. Although progress has been made over the last few decades in understanding mechanisms underlying the mind-body relationship, disparities remain between research and its clinical implementation. One possible reason for this is the lack of a comprehensive, agreed-upon model that incorporates a biopsychosocial framework and is rooted in an understanding of the various psychobiological pathways. Such a model would enable better communication between physicians and MHPs, allowing them to provide coordinated, stratified treatment. In this paper, four archetypal case studies, together with standard care options are presented to illustrate the current state of affairs. A four-tiered conceptual model of mind-body interrelationships based on pathophysiological and psychopathological mechanisms is suggested to help optimize the treatment of somatic complaints. This Four-Cluster model consists of: (1) Organic Conditions: Structural, or degenerative processes that can affect mood and psychological responses but are not clearly exacerbated by stress. (2) Stress Exacerbated Diseases: Biological disorders with a distinct pathophysiology, such as inflammatory or autoimmune diseases, whose progression is clearly exacerbated by stress. (3) Functional Somatic Syndromes: Conditions wherein heightened sensitivity to stimuli together with hyper-reactivity of the autonomic system form a "vicious cycle" of mutually enhancing learning processes. These processes involve biological mechanisms, such as central sensitization and psychological mechanisms such as catastrophization and selective attention. (4) Conversion Disorder: Physical manifestations of psychological distress, expressed somatically. Symptoms are solely an expression of problems in patients' psychic functioning and are not caused by biological pathology. Finally, suggested management of the aforementioned case studies is presented through the lens of the Four-Cluster model and a proposed integration of our model with existing theories is discussed. As it is rooted in an understanding of psychobiological pathways of illness, the proposed model enables a new way to discern which form of mind-body interaction is manifesting in different diseases and proposes a way to coordinate treatment plans accordingly, to enhance the accuracy and efficacy of care.

Acupuncture and the Cardiovascular System: A Scientific Challenge

In acupuncture research two main issues have to be addressed. One is whether the needle has a biological effect of its own. The other is whether acupuncture is of help to patients in their daily lives. With reference to this, acupuncture is a complex form of treatment in which the needles modulate physiological mechanisms of the body and the doctor supports the patient to achieve a life-style that assists with this.

To evaluate the biological effects of needling, a randomised, controlled trial group of 49 patients with angina pectoris had acupuncture while cardiological, neurophysiological and psychological observations were made in a mutually independent manner. Needling was found to improve the working capacity of the heart. In addition, acupuncture was found to activate cardiovascular autoregulatory mechanisms in 24 healthy persons.

To evaluate the effect of acupuncture in daily life, a controlled trial group of 69 patients with severe angina pectoris were followed for 2 years after treatment. The incidence of cardiac death or myocardial infarction was 7%, compared to 15–21% for the control group of published results concerning invasive treatments. Due to clinical improvement, surgery was postponed in 61% of the patients. The annual number of in-hospital days was reduced by 90%, leading to a US$ 12,000 saving for each patient.

Stratified Medical Therapy Using Invasive Coronary Function Testing in Angina: The CorMicA Trial

BACKGROUND

Patients with angina symptoms and/or signs of ischemia but no obstructive coronary artery disease (INOCA) pose a diagnostic and therapeutic challenge.

OBJECTIVES

The purpose of this study was to test whether an interventional diagnostic procedure (IDP) linked to stratified medicine improves health status in patients with INOCA.

METHODS

The authors conducted a randomized, controlled, blinded clinical trial of stratified medical therapy versus standard care in patients with angina. Patients with angina undergoing invasive coronary angiography (standard care) were recruited. Patients without obstructive CAD were immediately randomized 1:1 to the intervention group (stratified medical therapy) or the control group (standard care, IDP sham procedure). The IDP consisted of guidewire-based assessment of coronary flow reserve, index of microcirculatory resistance, fractional flow reserve, followed by vasoreactivity testing with acetylcholine. The primary endpoint was the mean difference in angina severity at 6 months (assessed by the Seattle Angina Questionnaire summary score).

RESULTS

A total of 391 patients were enrolled between November 25, 2016, and November 12, 2017. Coronary angiography revealed obstructive disease in 206 (53.7%). One hundred fifty-one (39%) patients without angiographically obstructive CAD were randomized (n = 76 intervention group; n = 75 blinded control group). The intervention resulted in a mean improvement of 11.7 U in the Seattle Angina Questionnaire summary score at 6 months (95% confidence interval [CI]: 5.0 to 18.4; p = 0.001). In addition, the intervention led to improvements in the mean quality-of-life score (EQ-5D index 0.10 U; 95% CI: 0.01 to 0.18; p = 0.024) and visual analogue score (14.5 U; 95% CI: 7.8 to 21.3; p < 0.001). There were no differences in major adverse cardiac events at the 6-month follow-up (2.6% controls vs. 2.6% intervention; p = 1.00).

CONCLUSIONS

Coronary angiography often fails to identify patients with vasospastic and/or microvascular angina. Stratified medical therapy, including an IDP with linked medical therapy, is routinely feasible and improves angina in patients with no obstructive CAD.

Health-Seeking Behaviour and Delayed Presentation of Oral Cancer Patients in a Developing Country: A Qualitative Study based on the Self-Regulatory Model

Background: The aim of this study was to explore reasons for delayed health-seeking for late stage oral cancer patients. Methods: Semi-structured in-depth interviews were conducted with 35 oral cancer patients with TNM stage III to IV disease, who were treated at six tertiary regional centres managing oral cancer throughout Malaysia. Interviews were audio-recorded, transcribed verbatim, coded using NVivo (version 10.0) qualitative software and analysed using framework analysis. Results: Participants interpreted their early symptoms as a minor condition and did not consider it as requiring immediate attention. Four types of coping strategies causing delayed help-seeking emerged: 1) self-remedy 2) self-medication 3) seeking traditional healers and 4) consulting general medical practitioners (GPs) instead of dentists. Socio-economic factors, cultural beliefs and religious practices have some influence on diagnostic delay. Conclusion: Low levels of public knowledge and awareness regarding early signs and symptoms of oral cancer as well as GPs’ misdiagnosis of early lesions results in delayed diagnosis.
