Correlation between retinal vein pulse amplitude, estimated intracranial pressure, and postural change

Spaceflight associated neuro-ocular syndrome (SANS) is common amongst astronauts on long duration space missions and is associated with signs consistent with elevated cerebrospinal fluid (CSF) pressure. Additionally, CSF pressure has been found to be elevated in a significant proportion of astronauts in whom lumbar puncture was performed after successful mission completion. We have developed a retinal photoplethysmographic technique to measure retinal vein pulsation amplitudes. This technique has enabled the development of a non-invasive CSF pressure measurement apparatus. We tested the system on healthy volunteers in the sitting and supine posture to mimic the range of tilt table extremes and estimated the induced CSF pressure change using measurements from the CSF hydrostatic indifferent point. We found a significant relationship between pulsation amplitude change and estimated CSF pressure change (p < 0.0001) across a range from 2.7 to 7.1 mmHg. The increase in pulse amplitude was highest in the sitting posture with greater estimated CSF pressure increase (p < 0.0001), in keeping with physiologically predicted CSF pressure response. This technique may be useful for non-invasive measurement of CSF pressure fluctuations during long-term space voyages.

[Special situations of preconditioning and prehabilitation in oncological visceral surgery]

BACKGROUND

Prehabilitation prior to complex visceral oncological surgery is playing an increasingly important role.

OBJECTIVE

The aim of this review article is to present special situations of preconditioning in visceral oncological patient cohorts. The following conditions were defined as special situations with subsequently increased risk profile: cardiopulmonary comorbidities, geriatric patients, neoadjuvant therapy and simultaneous fatigue.

MATERIAL AND METHODS

A selective literature review based on a search in the electronic databases MEDLINE, PubMed, Cochrane Library and the International Standard Randomization Controlled Trial Number (ISRCTN) was performed.

RESULTS

The identification of high-risk patients is an essential part of the preoperative evaluation conducted by the anesthesiologist prior to surgery. The cardiovascular and the pulmonary risk profile are determined by means of prediction indices evaluating patient-specific and surgery-related risk factors. The increased use of new oral anticoagulants and dual platelet aggregation inhibition requires individualized treatment strategies. Numerous studies have shown clinically relevant effects of exercise therapy interventions throughout all phases of oncological treatment. In addition to positive effects on therapy-associated side effects, sport can also counteract the effects of sedentary behavior in cancer patients and improve the health-related quality of life. The effectiveness of sport and exercise therapies as well as psychological interventions in oncological patients with fatigue (CRF) is broad, with important components being motivation and compliance.

DISCUSSION

In high-risk patients an interdisciplinary approach to planning and conduction of prehabilitation is essential for the early detection and optimization of perioperative risk factors and potential complications. The aim is faster recovery, reduced morbidity and mortality and the possibility to improve long-term survival and quality of life.

Attachment security and existential distress among patients with advanced cancer

BACKGROUND

Felt security in close relationships may affect individual adaptation responses to existential threat in severe illness. We examined the contribution of attachment security to demoralization, a state of existential distress involving perceived pointlessness and meaninglessness in advanced cancer.

METHOD

A mixed cross-sectional sample of 382 patients with advanced cancer (mean age 59, 60% female) was recruited from outpatient oncology clinics. Participants completed self-report measures of attachment security, demoralization, depression, and physical symptom burden. We used multiple linear regression to analyze the association between attachment security and demoralization, controlling for demographic factors and symptom burden and tested whether attachment security moderated the association of symptom burden with demoralization. Separate analyses compared the contribution of the dimensions of attachment anxiety and attachment avoidance.

RESULTS

The prevalence of clinically relevant demoralization was 35%. Demoralization was associated with lower attachment security (β = -0.54, 95%CI: -0.62 to 0.46). This effect was empirically stronger for attachment anxiety (β = 0.52, 95%CI: 0.44 to 0.60) compared to attachment avoidance (β = 0.36, 95%CI: 0.27 to 0.45). Attachment security also significantly moderated the association of physical symptom burden with demoralization, such that with less attachment security, there was a stronger association between symptom burden and demoralization.

CONCLUSION

Attachment security may protect from demoralization in advanced cancer. Its relative lack, particularly on the dimension of attachment anxiety, may limit adaptive capacities to deal with illness burden and to sustain morale and purpose in life. An understanding of individual differences in attachment needs can inform existential interventions for severely ill individuals.

Perceived stigmatization and its impact on quality of life - results from a large register-based study including breast, colon, prostate and lung cancer patients

BACKGROUND

To date, research on stigmatization among cancer patients and related psychosocial consequences has been scarce and mostly based on small and highly selected samples. We investigated stigmatization and its impact on quality of life among a large sample including four major tumor entities.

METHODS

We assessed 858 patients with breast, colon, lung or prostate cancer from two cancer registries. Stigmatization and quality of life (QoL) was assessed with the Social Impact Scale (SIS-D) and the EORTC Quality of Life Questionnaire (European Organization for Research and Treatment of Cancer), respectively. Group effects were analyzed via analyses of variance, relationships were investigated via Pearson's r and stepwise regression analyses.

RESULTS

The mean age was 60.7 years, 54% were male. Across cancer sites, the dimensions of stigmatization (isolation, social rejection, financial insecurity and internalized shame) were in the lower and middle range, with the highest values found for isolation. Stigmatization was lowest among prostate cancer patients. Stigmatization predicted all five areas of QoL among breast cancer patients (p < .05), but only affected emotional functioning (p < .01) among lung cancer patients.

CONCLUSIONS

We found an inverse relationship between perceived cancer-related stigmatization and various dimensions of QoL, with variation between cancer sites. Breast cancer patients should be focused in individual therapies regarding the negative consequences accompanied by perceived stigmatization.

The risk of being depressed is significantly higher in cancer patients than in the general population: Prevalence and severity of depressive symptoms across major cancer types

BACKGROUND

Depression is a common co-morbidity of cancer that has a detrimental effect on quality of life, treatment adherence and potentially survival. We conducted an epidemiological multi-center study including a population-based random comparison sample and estimated the prevalence of depressive symptoms by cancer site, thereby identifying cancer patients with the highest prevalence of depression.

PATIENTS AND METHODS

We included 4020 adult cancer inpatients and outpatients from five distinct regions across Germany in a proportional stratified random sample based on the nationwide cancer incidence and a comparison group consisting of 5018 participants. Both groups reported depressive symptoms by filling in the Patient Health Questionnaire (PHQ-9). In multivariate analyses adjusted for age and sex, we calculated the odds of being depressed.

RESULTS

Out of 5818 eligible patients, 69% participated (51% women, mean age = 58 years). We estimated that one in four cancer patients (24%) is depressed (PHQ-9 ≥ 10). The odds of being depressed among cancer patients were more than five times higher than in the general population (OR, 5.4; 95% CI, 4.6-6.2). Patients with pancreatic (M = 8.0, SD = 5.0), thyroid (M = 7.8, SD = 6.3) and brain tumours (M = 7.6, SD = 4.9) showed the highest prevalence, whereas patients with prostate cancer (M = 4.3, SD = 3.8) and malignant melanoma (M = 5.3, SD = 4.3) had the lowest levels of depressive symptoms.

CONCLUSION

Our results help clinicians identify cancer patients in need of psychosocial support when navigating in the growing survivor population.

Predictors of early retirement after cancer rehabilitation-a longitudinal study

This longitudinal study was designed to assess patients' desire for early retirement and investigate which cancer-related and psychosocial characteristics are associated with early retirement. We assessed 750 cancer patients at the beginning (t₀ ) and end (t₁ ) of, and 12 months after (t₂ ) inpatient cancer rehabilitation. At t₀ , 22% had a desire to retire early. These patients reported significantly longer sick leave periods, less favourable workplace environments, lower work ability, higher psychological distress and lower quality of life than other patients. At t₂ , 12.5% of patients received temporary or permanent early retirement pensions. Of all patients with a desire for early retirement at t₀ , 43% had returned to work at t₂ . This subgroup had a significantly lower physical quality of life than other patients returning to work. The most influential predictors of early retirement were being on sick leave (OR = 6.50, 95% CI = 1.97-21.47) and a desire for early retirement (OR = 5.61, 95% CI = 2.73-11.52). Inverse predictors of early retirement were cancer remission (OR = 0.23, 95% CI = 0.10-0.53), perceived productivity (OR = 0.38, 95% CI = 0.18-0.83), work satisfaction (OR = 0.36, 95% CI = 0.17-0.77) and mental quality of life (OR = 0.94, 95% CI = 0.91-0.98). This underlines the need for cancer-specific multi-professional rehabilitation and occupational therapy programmes.

[The Development of Quality Standards for the Psychosocial Outpatient Care of Cancer Patients - Results of a Delphi Survey]

BACKGROUND

The psychosocial outpatient care of cancer patients and their families is a central element of oncological care. To date, the provision of care to this group is very heterogeneous in terms of the spectrum of services offered and quality of care. The aim of this study was to develop a multidimensional classification of quality standards for psychosocial outpatient cancer counseling.

METHOD

We conducted a study using the Delphi method. 97 experts from more than 10 different fields of action or institutional contexts (e. g. mental health care professionals, cancer societies, self-help groups) were included in 3 rounds of Delphi assessment. Finally, 134 single criteria within 9 quality areas (e. g. staff, range of services, documentation) were generated and evaluated for their relevance, clarity, comprehensiveness and level of obligation.

RESULT

A total of 119 individual criteria (88.8%) achieved consensus within the 3 Delphi rounds. Hereof, 94 were basic criteria (79%) and 25 optional criteria (21%). The highest number of individual criteria referred to the service spectrum (26 individual criteria), documentation (21) as well as staff and accessibility (16 each). Fifteen criteria (11.2%) achieved no consensus and were removed.

CONCLUSION

For the first time, criteria for assessing the quality of psychosocial outpatient cancer counseling with expert consensus are available, facilitating the evaluation of psychosocial outpatient cancer counseling.

Anxiety and depression in long-term testicular germ cell tumor survivors

OBJECTIVE

Despite a good prognosis, the typically young age at diagnosis and physical sequelae may cause psychological distress in germ cell tumor survivors. We aimed to determine the frequency of anxiety and depression and analyze the impact of demographic and disease-related factors.

METHOD

We enrolled N=164 testicular germ cell tumor survivors receiving routine follow-up care at the University Cancer Center Hamburg and a specialized private practice (mean, 11.6 years after diagnosis). Patients completed the Generalized Anxiety Disorder Screener-7, the Patient Health Questionnaire-9 and the Memorial Symptom Assessment Scale-Short Form.

RESULTS

We found clinically significant anxiety present in 6.1% and depression present in 7.9% of survivors. A higher number of physical symptoms and having children were significantly associated with higher levels of both anxiety and depression in multivariate regression analyses controlling for age at diagnosis, cohabitation, socioeconomic status, time since diagnosis, metastatic disease and relapse. Younger age at diagnosis and shorter time since diagnosis were significantly associated with higher anxiety.

CONCLUSION

Although rates of clinically relevant anxiety and depression were comparably low, attention toward persisting physical symptoms and psychosocial needs related to a young age at diagnosis and having children will contribute to address potential long-term psychological distress in germ cell tumor survivors.

[Assessment of Work Engagement in Patients with Hematological Malignancies: Psychometric Properties of the German Version of the Utrecht Work Engagement Scale 9 (UWES-9)]

OBJECTIVE

Our purpose was the psychometric evaluation of the German version of the Utrecht Work Engagement Scale-9 (UWES-9), a self-assessment tool measuring work-related resources consisting of 9 items.

METHODS

Based on a sample of 179 patients with hematological malignancies in in-patient and rehabilitative oncological settings, we tested the dimensional structure by confirmatory and explorative factor analysis. We further evaluated reliability, item characteristics, and construct validity of the UWES-9.

RESULTS

The confirmatory factor analysis showed acceptable fit for both a 1-dimensional factor structure and the original 3-factor model. Based on an explorative principal component analysis, we were able to replicate the 1-dimensional factor accounting for 67% of the total variance and showing very high internal consistency (α=0.94) and high factor loads (0.73-0.88). The construct validity was further supported by significant positive correlations between work engagement and meaning of work, corporate feeling, commitment to the workplace, and job satisfaction.

CONCLUSION

The German version of the UWES-9 shows good psychometric qualities in measuring dedication to work in patients with hematological malignancies in in-patient and rehabilitative oncological settings.

[Communication Bad News by Physicians: The German Version of the MPP (Measure of Patients' Preferences) Questionnaire to the Communicative Preferences of Cancer Patients]

OBJECTIVES

Breaking bad news is as one of the most distressing tasks that doctors face with high demands on their communication and psychosocial skills. Patient preferences for communicating bad news influence the course of such consultations. The purpose of this study was to evaluate the psychometric characteristics of the German version of the Measure of Patients' Preferences (MPP), a questionnaire that has been validated in several international studies.

METHOD

Statistical analyses were performed in a sample of N=270 cancer patients during early treatment phase (mixed cancer entities, mean age 56.9 years, 46.7% female). In this prospective study with 2 assessment times, the factorial structure of the MPP-D was examined using principal components analysis with varimax rotation.

RESULTS

Factor analysis resulted in a 9-factor solution, the 3 factor structure of the original version was not replicated. Cronbachs α was>0.80 for 7 of the MPP-D subscales indicating good to excellent reliability.

CONCLUSION

Further psychometric testing and optimisation of the measure is recommended.

[Structural and process quality in outpatient psychosocial cancer counselling centres. evaluating a major funding programme of the "Deutsche Krebshilfe e.V."]

BACKGROUND

In 2007, the German Cancer Aid ("Deutsche Krebshilfe e.V.") initiated and funded a programme in 28 selected cancer counselling centres in Germany attempting to both promote and strengthen quality assured psychosocial cancer counselling as well as to ensure long-term financing. The accompanying evaluation programme aims to collect structural data of the institutions and to evaluate processes of quality assurance within the sample of cancer counselling centres.

METHODS

On the basis of structured research within scientific databases and internet, as well as with the support of experts, characteristics of structural quality of cancer counselling centres were identified. Structural data were collected using a self-developed questionnaire and a semi-structured interview during the on-site visitations of the institutions.

RESULTS

The results show homogeneity in some fields of structural quality such as individual psycho-oncological and social counselling, human resources, room facilities, quality assurance, diagnostics, documentation and public relations. Structural quality of the investigated centres appears more heterogeneous with regard to aspects such as availability and accessibility, barrier-free access, group support offers (counselling, sports, arts, etc.) as well as cooperation, financing and written mission statements.

CONCLUSION

The investigated cancer counselling centres ensure mainly good minimum standards according to structural quality of cancer counselling. There is potential for further optimisation including cooperation, quality assurance, room facilities and being differentiated in terms of conceptual content and working concepts. Further achievements on quality assured cancer counselling can use the presented data as a basis for describing minimum standards and obligatory quality criteria.

Exploring spiritual needs and their associated factors in an urban sample of early and advanced cancer patients

Although it is widely recognised that people turn to spirituality in times of crises, the interest in exploring the spiritual needs of cancer patients is just beginning to grow. The purpose of this study was to conduct a spiritual needs assessment with cancer patients living in a Northern European metropolitan region in order to (a) examine the relevance and nature of spiritual needs; (b) to clarify the role of demographic and clinical characteristics in spiritual needs; and (c) to identify their associations with dimensions of psychological distress. N = 285 outpatients with mixed cancer sites and of all tumour stages were surveyed cross-sectionally. Instruments included the Spiritual Needs Questionnaire (SpNQ) and measures of anxiety, distress, hopelessness and meaning-related life attitudes. Almost all patients (94%) reported at least one spiritual need. The needs for Inner Peace and Actively Giving emerged to be of greatest importance. Significant, but weak differences were found for age, gender and being in a partnership. No associations for medical characteristics were observed. Regression analyses revealed anxiety as the strongest predictor for the subscales Existential Needs, Inner Peace and Actively Giving. The results emphasise the relevance of spiritual needs in cancer patients. The call for spiritual assessment and interventions to meet spiritual needs in cancer patients is strengthened.

[Vocational rehabilitation after total laryngectomy]

BACKGROUND

Aim of this study was to find out how many patients after a total laryngectomy (TLE) return to work successfully and what factors support vocational rehabilitation.

PATIENTS AND METHODS

Laryngectomees (n=231) aged up to 60 years completed questionnaires and structured interviews before TLE (t1), before rehabilitation (t2), at the end of rehabilitation (t3), 1 year after TLE (t4), 2 years after TLE (t5), and 3 years after TLE (t6).

RESULTS

Prior to TLE, 38% of all respondents were employed, 34% were unemployed, 23% received disability-related and 3% age-related pension retirement. One year after TLE, 13% were employed, 15% 2 years and 14% 3 years after TLE. Unemployed were 10% (t4), 5% (t5), and 7% (t6) of the patients. For 59% of all respondents it was very important to have a job. Predictors of successful vocational rehabilitation were employment prior to TLE, age <50 years, being self-employed or clerical employee, good physical functioning, good speech intelligibility, high motivation to go back to work, and support from colleagues.

CONCLUSION

Only few laryngectomees return to work. However, even before TLE only a third of the patients was employed, another third was unemployed. Most of the patients receive pension retirement after TLE. As return to work is important for many patients, patient consultations should consider possibilities to support vocational rehabilitation before offering to apply for retirement.

[Doctor-patient interaction: dealing with difficult situations]

Good doctor-patient communication has a positive impact on patient satisfaction, adherence to treatment, health outcomes and well-being, and it has been linked to reduced anxiety, increased recall, and improved understanding. During the diagnostic phase and the course of the illness, patients exhibit a range of mood changes. These include sadness and worry, frustration and anger, uncertainty, fear of disease recurrence, difficulties in inter-personal relationships, changing roles, and concerns about body image. Medical consultations can be influenced by different expectations concerning the doctor-patient interaction, by individual roles and beliefs, and by a different understanding of health and well-being influenced by cultural and other factors not necessarily associated with the medical situation. Responding to anger and other difficult emotions, dealing with family meetings, or communicating via interpreters are often experienced as demanding situations by health care professionals. This article provides an overview of the difficult doctor-patient interactions and illustrates basic communication skills in responding to challenging situations.

Depression, anxiety, post-traumatic stress disorder and health-related quality of life and its association with social support in ambulatory prostate cancer patients

The aim of this study is to identify anxiety, depression and post-traumatic stress disorder in prostate cancer patients and to investigate the association with social support and health-related quality of life. A total of 511 men who had undergone prostatectomy were surveyed during ambulatory follow-up care for an average of 27 months after surgery using standardised self-report measures (e.g. Hospital Anxiety and Depression Scale, Posttraumatic Stress Disorder Checklist--Civilian Version, Illness-Specific Social Support Scale, Short-Form Health Survey). Seventy-six per cent of patients evaluated their disease as 'not' or a 'little threatening'. The cancer diagnosis and uncertainty were most frequently reported as 'distressing', while medical treatment and doctor-patient interaction were most frequently evaluated as 'most helpful'. The number of patients reporting increased levels of psychological distress was 16%, with 6% demonstrating signs of having severe mental health problems'. No higher levels of anxiety and depression were observed in cancer patients compared with age-adjusted normative comparison groups. Lack of positive support, detrimental interactions and perceived threat of cancer were found to be predictors of psychological co-morbidity (P < 0.001). Lack of positive support, detrimental interactions, threat of cancer, disease stage and age significantly predicted mental health (P < 0.001), whereas the impact of social support on physical health was rather weak. Findings emphasise the need for routine psychosocial screening.
