Where do cancer patients die in Greece? A population-based study on the place of death in 1993 and 2003

Several studies have shown that place of death is affected by many parameters. Our objective was to describe for the first time where patients with cancer die in Greece and what has changed between 1993 and 2003. We acquired data on all deaths that were attributed to cancer in Greece in the years 1993 and 2003, and compared these data to the changes in the location of death in the total population. In 1993, approximately 50.7% of men and 50.9% of women cancer patients died in hospital, while in 2003, the respective percentages were 57.3% and 56.1%. The results indicate a trend toward a larger proportion of hospital deaths over this interval. This should be taken under consideration for future planning of end-of-life care in Greece.

Self-efficacy beliefs and levels of anxiety in advanced cancer patients

The aims of this study were to investigate the self-efficacy and anxiety in advanced cancer patients in a palliative care unit. The subject is some 99 advanced cancer patients, treated for pain relief and cancer-related symptoms. Patients completed the General Perceived Self-Efficacy Scale (GSE) and the Spielberger's State-Trait Anxiety Inventory (STAI). The Eastern Cooperative Oncology Group was used to measure patients' performance status. Statistically significant associations were found between GSE, patients' gender, performance status, opioids and all the STAI scales. The multiple regression analysis revealed that self-efficacy was predicted by patients' age, performance status, gender, as well as by their high levels on two STAI scales, in a model explaining 39.7% of the total variance. In advanced cancer patients, self-efficacy is significantly correlated with levels of anxiety, patients' physical condition and demographic characteristics. Also, it seems to be influenced by components of the STAI, patients' age, physical performance and gender.

The Incidence of Place of Death in Greek Patients with Cancer in 1995 and 2005

Purpose: To describe where (home or hospital) patients with cancer die in Greece, in 1995 and 2005. Methods: We used data from patients with cancer, who died in Greece in 1995 and 2005, and we studied the location changes of death in the 3 major geographical areas of Greece (Macedonia: North Greece, Central Greece, and Crete: South Greece). Results: In Central Greece and Crete, death incidences for 60 to 69, 70 to 79, and 80+ age groups decreased from 1995 to 2005. In Crete, in 1995, male and female death incidences for 80+ age group dying at home was higher than the corresponding one dying in hospital. Conclusion: It seemed that in Greece, more cancer patients are dying in hospitals. Geographical and socioeconomic criteria might affect the place of death of a patient with cancer.

Illness-related hopelessness in advanced cancer: influence of anxiety, depression, and preparatory grief

The growing interest in the psychological distress in patients with cancer has been the major reason for the conduction of this study. The aims were to assess the relationship of hopelessness, anxiety, distress, and preparatory grief, as well as their predictive power to hopelessness. Ninety-four patients with advanced cancer completed the study at a palliative care unit in Athens, Greece. Beck Hopelessness Scale, the Greek version of the Hospital Anxiety and Depression (HAD) scale, and the Preparatory Grief in Advanced Cancer Patients scale were administered. Information concerning patients' treatment was acquired from the medical records, whereas physicians recorded their clinical condition. Hopelessness correlated significantly with preparatory grief (r = .630, P < .0005), anxiety (r = .539, P < .0005), depression (r = .642, P < .0005), HAD-Total (r = .686, P < .0005), and age (r = -.212, P = .040). Multiple regression analyses showed that preparatory grief (P < .0005), depression (P < .0005), and age (P = .003) were predictors of hopelessness, explaining 58.8% of total variance. In this patient sample, depression, preparatory grief, and patients' age were predictors of hopelessness.

The relationship between quality of life and levels of hopelessness and depression in palliative care

There is growing interest in the psychological distress and quality of life of cancer patients. The aim of this study was to compare the responses of 102 advanced cancer patients on a quality of life scale (as measured by the SF12) with the Beck Depression Inventory (BDI) and the Beck Hopelessness Scale (BHS), as well as the impact of depression and hopelessness on quality of life. Significant associations were found between gender (P=.027), performance status (P=.003), opioids (P=.002), depression (P<.0005), and hopelessness (P<.0005) with the SF12-Mental Component Score (MCS). Gender (P=.07), metastasis (P=.001), opioids (P=.0005), and education (P=.045) correlated significantly with SF12-Physical Component Score (PCS). In the prediction of MCS, the dimensions of age, hopelessness, gender, and performance status were statistically significantly high (P<.0005), explaining 48% of variance. For PCS, the predictor variables were education, metastasis, and opioids (25% of variance). Quality of life, in this patient population, was predicted by the level of hopelessness and patients' demographic and clinical characteristics.

How is sleep quality affected by the psychological and symptom distress of advanced cancer patients?

The aim of this study was to assess the relationship between sleep quality, pain, psychological distress, cognitive status and post-traumatic experience in advanced cancer patients. Participants were 82 advanced cancer patients referred to a palliative care unit for control of pain and other symptoms. A variety of assessment tools were used to examine the prevalence of sleep disturbance, the severity of pain and depression, hopelessness, cognitive function and quality of life. Using the Pittsburgh Sleep Quality Index (PSQI) 96% of patients were 'poor sleepers'. Statistically significant associations were found between PSQI and the SF-12 (Short Form-12) Quality of Life Instrument (MCS, P < 0.0005, PCS, P < 0.0005), depression (Greek Depression Inventory) (P < 0.0005) and hopelessness (Beck Hopelessness Scale) (P = 0.003). Strong associations were also found between PSQI and IES-R (Impact of Event Scale-Revised) (P = 0.004). The strongest predictors of poor sleep quality in this model were MCS (P < 0.0005), PCS (P < 0.0005) and IES-R (P = 0.010). Post-traumatic experience and quality of life seemed to be the strongest predictors of sleep quality in a sample of advanced cancer patients referred for palliative care.

Predictors of spirituality at the end of life

OBJECTIVE

To assess the relationship between spirituality and hopelessness, desire for hastened death, and clinical and disease-related characteristics among patients with advanced cancer, and to investigate predictors of spirituality. Spiritual well-being is thought to have a beneficial effect on patients' response to illness.

DESIGN

Patients were asked to complete 4 questionnaires: the Greek version of the Spiritual Involvement and Beliefs Scale, the Greek version of the Schedule of Attitudes toward Hastened Death, the Beck Hopelessness Scale, and a questionnaire on demographics.

SETTING

A palliative care unit in Athens, Greece.

PARTICIPANTS

A total of 91 patients with advanced cancer.

MAIN OUTCOME MEASURES

Associations between scores on the Spiritual Involvement and Beliefs scale and scores on the Schedule of Attitudes toward Hastened Death scale and the Beck Hopelessness scale, and demographic characteristics.

RESULTS

Statistically significant associations were found between spirituality and sex of patients (P = .001) and spirituality and stronger hopelessness (r = 0.252, P = .016). In multivariate analyses, stronger hopelessness, male sex, younger age, and receiving chemotherapy were found to be the strongest predictors of being spiritual.

CONCLUSION

Demographic and clinical characteristics and stronger hopelessness appeared to have statistically significant relationships with spirituality. Interventions to improve patients' spiritual well-being should take these relationships into account.

Oral Transmucosal Fentanyl Citrate: Overview of Pharmacological and Clinical Characteristics

Oral transmucosal fentanyl citrate (OTFC; brand name Actiq, Cephalon, UT) is a new opioid formulation that incorporates fentanyl into a lozenge and allows drug delivery through the buccal mucosa. This kind of absorption avoids first-pass metabolism, yielding a bioavailability substantially greater than oral administration. OTFC has a rapid onset of action and a short duration of effect. These characteristics, which resemble the course of a typical breakthrough pain episode, resulted in making OTFC the first opioid analgesic formulation specifically developed and approved for control of breakthrough pain in cancer patients. Apart from that, OTFC has been used in a variety of clinical situations of noncancer pain. This review article presents the synthesis; clinical pharmacology; pharmacokinetic and pharmacodynamic properties, toxicity, and clinical efficacy of this novel agent.

Euthanasia and physician-assisted suicide in cases of terminal cancer: the opinions of physicians and nurses in Greece

The aim of this study was to investigate the opinions of physicians and nurses on euthanasia and physician-assisted suicide in advanced cancer patients in Greece. Two hundred and fifteen physicians and 250 nurses from various hospitals in Greece completed a questionnaire concerning issues on euthanasia and physician-assisted suicide. More physicians (43.3%) than nurses (3.2%, p < 0.0005) reported that in the case of a cardiac or respiratory arrest, they would not attempt to revive a terminally ill cancer patient. Only 1.9% of physicians and 3.6% of nurses agreed on physician-assisted suicide. Forty-seven per cent of physicians and 45.2% of nurses would prefer the legalization of a terminally ill patient's hastened death; in the case of such a request, 64.2% of physicians and 55.2% of nurses (p = 0.06) would consider it if it was legal. The majority of the participants tended to disagree with euthanasia or physician-assisted suicide in terminally ill cancer patients, probably due to the fact that these acts in Greece are illegal.

Psychometric properties of the brief fatigue inventory in Greek patients with advanced cancer

To validate the Greek version of the Brief Fatigue Inventory (BFI-Gr) in a sample of cancer patients, the scale was translated with the "forward-backward" procedure to Greek. It was administered twice, at a three-day interval, to 102 eligible patients with cancer. Together with the BFI-Gr scale, the patients also completed the European Organization for Research and Treatment of Cancer QLQ-C30 (version 3.0) subscales of fatigue and emotional functioning, and the M. D. Anderson Symptom Inventory. The BFI-Gr had an overall Cronbach alpha for the nine items of 0.954. The assessment of the relationships between the BFI-Gr and the other measurements showed statistically significant correlations between all the assessed measurements (r values between 0.47 and 0.76, P<0.0005), except with the emotional subscale of the European Organization for Research and Treatment of Cancer scale. Factor analysis yielded a one-factor solution, explaining 73.6% of the variance. Interitem correlations were high and ranged from 0.567 to 0.882 (P<0.0005). The test-retest reliability of scale showed that the coefficient agreement was 0.901 (P<0.0005). Univariate analysis revealed significant correlations between hemoglobin and fatigue (r=-0.21, P=0.037), and between performance status (P<0.0005) and opioids (P=0.009). These results support that the BFI-Gr is an instrument with satisfactory psychometric properties, and is a valid research tool for cancer-related fatigue in Greek cancer patients.

Demographic and clinical predictors of spirituality in advanced cancer patients: a randomized control study

AIM

To study the influence of cancer patients' sociodemographic and clinical characteristics in their spiritual beliefs and attitudes.

BACKGROUND

Patients' sociodemographic and clinical characteristics may have an important role in their spirituality. Failure to control these factors can lead to a false estimation on patients' spiritual beliefs. Previous studies have found that age, gender and health status associate with spiritual attitudes and beliefs.Design. Survey.

METHODS

The Spiritual Involvement and Beliefs Scale was administered to 82 cancer patients. Demographic characteristics, disease status and treatment regimen were recorded.

RESULTS

Among the most significant correlations were those between gender and all the subscales, cancer diagnosis, existential/meditative subscale, radiotherapy treatment and external/ritual, internal/fluid and existential meditative. In the prediction of spirituality, the contribution of gender, age, years of education, performance status and radiotherapy is high.

CONCLUSION

Acknowledging the specific patients' demographic and medical characteristics, such as female gender, old age, years of education, performance status and radiotherapy treatment, contributes to the prediction of patients' spiritual beliefs and attitudes.

RELEVANCE TO CLINICAL PRACTICE

Addressing spiritual needs in palliative care among the dying needs to be a priority and could be a crucial aspect of psychological functioning, especially when considering certain demographic and clinical characteristics.

Granulosa Cell Tumor of the Ovary: Tumor Review

Granulosa cell tumors of the ovary are rare neoplasms that originate from sex-cord stromal cells. The long natural history of granulosa cell tumors and their tendency to recur years after the initial diagnosis are the most prominent of their characteristics. The secretion of estradiol is the reason for signs at presentation such as vaginal bleeding and precocious puberty. Abdominal pain and hemoperitoneum, which occasionally can occur, are attributable to tumor rupture. The most common finding in pelvic examination is a tumor mass, which is subsequently confirmed with imaging techniques. Surgery is the mainstay of initial management for histological diagnosis, appropriate staging, and debulking. A more conservative unilateral salpingo-oophorectomy is indicated in patients with stage I disease and patients of reproductive age. Total abdominal hysterectomy with bilateral salpingo-oophorectomy is the appropriate surgical treatment for postmenopausal women and those with more advanced disease. The stage of disease is the most important prognostic factor associated with the risk of relapse. There are no clear conclusions regarding the role of postoperative chemotherapy or radiotherapy in stage I disease and in those with completely resected tumor. The use of adjuvant chemotherapy or radiotherapy has sometimes been associated with prolonged disease-free survival and possibly overall survival. Chemotherapy is the treatment of choice for patients with advanced, recurrent, or metastatic disease, and BEP (bleomycin, etoposide, and cisplatin) is the preferred regimen. Although the overall rate of response to treatment is high, the impact of treatment on disease-free or overall survival is unknown. Prolonged surveillance is mandatory because tumors tend to recur years after the initial diagnosis.

Personal growth and psychological distress in advanced breast cancer

AIMS

The experience of posttraumatic growth following breast cancer, its association with psychological distress and the predictive value of psychological distress, sociodemographic and clinical characteristics of cancer patients in their personal growth.

METHODS

The Posttraumatic Growth Inventory and the Greek version of the Hospital Depression and Anxiety Scale (G-HADS) were administered to 100 breast cancer patients. Sociodemographic and clinical characteristics were recorded.

RESULTS

The analysis showed that significant associations were found between PTGI-Total patients' age (p=0.001), and being married (p=0.007). Moreover, significant negative association was observed between PTGI-II ("New Possibilities") and HADS-Depression (r=-0.314, p<0.05). Multiple regression analyses showed that age is a significant predictor of PTGI-II ("New Possibilities") (p=0.005), PTGI-V ("Appreciation of Life") (p=0.0005) and PTGI-Total (p=0.037), while marital status is a significant predictor of PTGI-Total (p=0.009).

CONCLUSION

Specific patients' characteristics, such as young age and being with a partner, influence the experience of posttraumatic growth in breast cancer patients.

The experience of hopelessness in a population of Greek cancer patients receiving palliative care

BACKGROUND

Beck Hopelessness Scale (BHS) has been translated and validated in many languages.

AIM

The validation of the English version of BHS in advanced cancer patients receiving palliative treatment in Greece.

METHODS

The final sample was 112 advanced cancer patients. Internal consistency, item-total correlations, and test-retest using four different approaches were calculated for the assessment of the reliability. Construct validity was used by examining correlations between BHS, Hospital Anxiety and Depression Scale (HAD-Depression) and the Schedule of Attitudes toward Hastened Death (SAHD). Known-groups validity was also assessed by detecting group differences according to disease severity as measured by the Eastern Cooperative Oncology Group (ECOG) performance status. Univariate and multivariate analyses were constructed to explore the relationship between hopelessness, depression, hastened death and the patients' demographic and clinical characteristics.

RESULTS

One factor solution was yielded accounted for 46.64% of the variance. The test-retest reliability was satisfactory (p < 0.0005). Validity as performed using known-group analysis showed good results. Most significant correlations were found between BHS, ECOG (p = 0.018) and gender (p = 0.08). The strongest predictors were gender (p = 0.050) and ECOG (p = 0.045).

CONCLUSIONS

BHS seemed to be a useful instrument to assess pessimistic attitude and hopelessness in a Greek cancer population, with valid psychometric properties.

Depression, hopelessness, and sleep in cancer patients' desire for death

OBJECTIVE

The aim of this study was to evaluate the prevalence of clinical characteristics and risk factors for hastened death in advanced cancer patients.

METHODS

Patients completed the Greek version of Schedule of Attitudes toward Hastened Death (G-SAHD), a sleep quality measure, the Pittsburgh Sleep Quality Index (PSQI), a Greek version of a depression inventory, the Beck Depression Inventory (BDI), a hopelessness scale, the Beck Hopelessness Scale (BHS), and a Visual Analogue Scale (VAS) for the assessment of pain.

PATIENTS

The final sample consisted of 102 terminally ill cancer patients attending a Palliative Care Unit.

RESULTS

Statistically significant associations were found between G-SAHD and patients performance status (ECOG) (chi2 = 8.62, p = 0.003). Strongest associations were observed between desire for death, depression, and hopelessness (r = 0.468, p < 0.0005, r = 0.678, p < 0.0005, respectively). In the prediction of G-SHAD the contribution of "hopelessness" (p < 0.0005), "depression" (p < 0.0005), "use of sleeping medication" (p < 0.0005), and "sleep quality" (p = 0.001) was high (59% of variance).

CONCLUSION

Depression, hopelessness, and sleep quality appeared to have a statistically significant relationship with desire for hastened death. Health care professionals finding desire for death in advanced cancer patients should not only consider depression and hopelessness, but also other factors such as poor sleep quality in their diagnostic formulations in order to provide the appropriate treatment.

Traumatic distress and positive changes in advanced cancer patients

This study investigated the traumatic distress and posttraumatic growth in 58 advanced cancer patients receiving palliative treatment in a Pain Relief and Palliative Care Unit. The patients completed the Greek version of the Impact of Events Scale-Revised and the Posttraumatic Growth Inventory. Statistically significant associations were found among Impact of Events Scale-Revised-Greek "Relating to Others" (r = 0.311, P = .017), "New Possibilities" ( r = 0.248, P = .050), and "Appreciation of Life" ( r = 0.419, P = .001), and the Posttraumatic Growth Inventory scores (r = 0.323, P = .013). Similarly, "Appreciation of Life" correlated significantly with "Avoidance" (r = 0.318, P = .015), "Intrusion" (r = 0.365, P = .005), and "Hyperarousal" (r = 0.398, P = .002). Statistically significant associations were also found between "Relating to Others" and "Intrusion" (r = 0.414, P = .001). The study concluded that in advanced cancer patients, the higher the impact event, the more improvement in their relationships with others, enhanced life appreciation, and more positive consequences after trauma.

Erythropoietic growth factors for children with cancer: a systematic review of the literature

OBJECTIVE

To review evidence on the use of erythropoietic stimulating agents (erythropoietin or darbepoetin) in children with cancer.

METHODS

A systematic review of the published literature was performed using MEDLINE (1966-July 2007) and references from a Cochrane systematic review (focusing mainly on adults) published in 2006.

RESULTS

The review identified 12 studies, comprising five randomized trials, six case control studies and one open-label, dose-escalation study. All the studies that used adequate doses of recombinant human erythropoietin (rhEPO) (usually 150 IU/kg three times per week) demonstrated benefits for rhEPO except for one study in which rhEPO was added to G-CSF in children with high-risk neuroblastoma. Despite the heterogeneity of the populations studied, in terms of age, tumour type and chemotherapy regimen, rhEPO use was associated with consistent benefits in terms of reduced transfusion requirements and improved haematological parameters. Only one case of darbepoietin use was reported.

CONCLUSIONS

While more studies are required, it appears that rhEPO is safe in this vulnerable patient group and can benefit children with cancer by preventing or ameliorating anaemia.

Beck Depression Inventory: exploring its psychometric properties in a palliative care population of advanced cancer patients

To validate the Greek version of the Beck Depression Inventory (BDI)-21 items in advanced cancer patents attending a palliative care unit. The scale was translated with the forward-backward procedure into Greek. It was administered twice, with a 1-week interval, to 105 patients with advanced cancer. The patients also completed the Hospital Anxiety and Depression (HAD) scale, while researchers recorded data on demographic characteristics, disease status and treatment regimen. The Greek version of the BDI had overall Cronbach's alpha 0.906. The most significant correlations were found between BDI and performance status (P < 0.0005), gender (P = 0.031) and family status (P = 0.009). The test-retest reliability in terms of Spearman-rho, Pearson-rho coefficient and Kendall's tau-b was also satisfactory (P < 0.0005). Validity as performed using known-group analysis showed good results. The Inventory discriminated well between subgroups of patients differing in disease severity as defined by the Eastern Cooperative Oncology Group performance status. Correlations between the BDI and the HAD scale was 0.544 for the anxiety subscale and 0.657 for the depression subscale. Multiple regression analysis was conducted and predicted that the contribution of gender, family status and performance status to BDI is high. These psychometric properties of the Greek version of the BDI confirm it as a valid and reliable measure when administered to patients with advanced cancer.

Post-traumatic growth in advanced cancer patients receiving palliative care

GOALS OF WORK

To develop the Greek version of the Post-traumatic Growth Inventory (PTGI-Gr), and assess its psychometric properties in a palliative care patient sample.

PATIENTS AND METHODS

The scale was translated with the forward-backward procedure to Greek. It was administered twice, with a 3-day interval, to 131 eligible patients with advanced cancer. Together with the PTGI, the patients also completed the Greek version of the Impact of Events Scale-Revised scale (IES-R-Gr). The reliability was assessed by the internal consistency (Cronbach's alpha coefficients), test/retest (Spearman's r value), and inter-item correlations. Validity was demonstrated by factor analysis, inter-scale correlations, construct validity with the IES-R-Gr, and combined with the Eastern Cooperative Oncology Group (ECOG) performance status.

MAIN RESULTS

The PTGI-Gr yielded a five-factor structure, explaining 73.5% of the variance. Cronbach's alphas for the five factors ranged from .66 to .87, respectively. Overall test-retest reliability was satisfactory with a range between .85 and .92 (p<.0005), and inter-item correlations ranged between .47 and .63. Inter-scale correlations were found satisfactory (p<.0005, p<.005, and p<.05). Validity as performed using combined validity analysis showed good results. Satisfactory construct validity was supported by the correlation analysis between the PTGI-Gr and the IES-R-Gr scales.

CONCLUSIONS

PTGI-Gr is an instrument with satisfactory psychometric properties, and is a valid research tool for the post-traumatic growth of advanced cancer patients.

Oral transmucosal fentanyl citrate in cancer pain management: a practical application of nanotechnology

Pain is experienced by most cancer patients and represents an important issue in the clinical setting. Breakthrough pain is a transitory flare of pain that occurs in most cancer patients on a background of otherwise controlled persistent pain. Treatment of breakthrough pain is a challenging phenomenon. Oral transmucosal fentanyl citrate (OTFC; Actiq, Cephalon, UK), a new opioid formulation with a unique delivery system, utilizing the advantages that nanotechnology offers, reflects the characteristics of breakthrough pain (rapid onset of action and short duration), which makes it an effective treatment to cancer patients who are already receiving opioids and continue to experience such flares of pain. Oral transmucosal fentanyl citrate is specifically developed and approved for the management of breakthrough pain in cancer patients and it has the potential to be a useful tool for clinicians.

Caregivers of Advanced Cancer Patients

To investigate whether the advanced cancer patients' caregivers' depression and hopelessness are affected by patients' demographic and clinical characteristics and by caregivers' sociodemographic variables. Moreover, the relation between cancer patients' and caregivers' depression and hopelessness was assessed. One hundred five patients with advanced cancer receiving palliative care and 96 caregivers were enrolled in the study. The patients and their caregivers completed the Beck Depression Inventory and the Beck Hopelessness Scale while researchers recorded data on demographic characteristics, disease status, and treatment regimen. The analysis showed that significant associations were found between patient male sex and caregiver's depression (P = .007) and hopelessness (P = .002), between patient family status and caregiver's depression (P = .031) and hopelessness (P = .001), and between patient radiotherapy treatment and caregiver's hopelessness (P = .017). Moreover, statistically significant correlation was found between patient's and caregiver's depression (P = .041). Generalized estimating equations showed that the patients characteristics that predicted caregivers' hopelessness were family status (P = .017), radiotherapy (P = .025), and the caregiver's relation to patient (P = .059). The findings suggest that caregiver's hopelessness is predicted by cancer patient's characteristics and that patient's depression is correlated to that of caregiver. The findings provide a base for future research.

Norepinephrine in Small-For-Size Liver Grafts: An Experimental Study in Pigs

BACKGROUND

Norepinephrine plasma levels may play a role in small-for-size grafts dysfunction at the early posttransplant period.

MATERIALS AND METHODS

The 18 pigs used as recipients were assigned to group 1 (n = 6), group 2 (n = 6), and group 3 (n = 6) and given grafts with graft-to-recipient volume ratios of 1:1, 2:3, and 1:3, respectively. Blood serum norepinephrine was measured by high-performance liquid chromatography with electrochemical detection at the following time points: pre-anhepatic period (baseline); anhepatic period; and 30, 60, 180, and 360 min after reperfusion. Graft arterial and portal vein flows were obtained 30, 60, 180, and 360 min after reperfusion by the aid of an ultrasonic flowmeter. Aspartate transferase (AST) and international normalized ratio (INR) were measured before the procedure (baseline), and at 180 and 360 min after reperfusion.

RESULTS

Anhepatic phase was characterized by a significant increase (6- to 8-fold) of norepinephrine in all groups (P < 0.05). In groups 1 and 2 plasma norepinephrine returned to normal values 30 min after reperfusion. In group 3, plasma norepinephrine remained significantly increased at every time point of the study compared to groups 1 and 2 (P < 0.001). Hepatic artery and portal vein flows in group 3 were significantly (P < 0.05) reduced and increased, respectively, compared to groups 1 and 2 at all times measured. Liver function tests (AST and INR) 360 min after reperfusion were significantly higher in group 3 compared to groups 1 and 2.

CONCLUSIONS

Norepinephrine levels are increased in very small-for-size grafts and this increase may be associated with early graft dysfunction.

The relationship of subjective sleep quality, pain, and quality of life in advanced cancer patients

STUDY OBJECTIVES

Cancer patients have been reported to complain about poor quality of sleep. This study evaluated the quality of sleep in this group, utilizing demographic data and clinical features of the cancers as assessment criteria. A secondary aim was to evaluate the correlation between the self-rated questionnaire for the quality of sleep with other instruments used in measuring pain and quality of life.

DESIGN

A total of 102 patients with stage IV cancer completed the study and were subsequently followed for up to 10 months. Self-rated questionnaires were administered for the evaluation of quality of sleep (PSQI), quality of life Medical Outcomes Study 12-item short-form (SF-12) questionnaire, the Mental Component Summary (MSC) and the Physical Component Summary (PCS), and pain (VAS Pain). The mediation analysis model was also used to evaluate how quality of life can influence the quality of sleep through its relation to pain, the performance status of patients and analgesics (Opioids).

PATIENTS

The mean age of the study participants was 62.8 (range: 26.0-87.0) years old. The majority (70.6%) of the patients presented with ECOG score between 2 and 3 and with metastasis (58.8%).

RESULTS

Mean Global Sleep Quality score was 12.0+/-4.6. The use of the PSQI questionnaire in cancer patients demonstrated that these subjects were prone to sleep poor quality. However, the various demographic variables and clinical features of the cancers did not affect quality of sleep. Global Sleep Quality scores from the PSQI correlated with the scores obtained from the SF-12 questionnaire and with the VAS Pain results, indicating a relationship between quality of sleep, quality of life and pain. However, only the SF-12 questionnaire had predictive value on quality of sleep. Mediation analysis showed that quality of life influences quality of sleep both directly and indirectly by its effect on pain. In addition, some of the effect of quality of life on sleep quality was mediated by the use of opioids.

CONCLUSIONS

Quality of sleep in patients suffering from stage IV cancer was significantly decreased. Demographic data and clinical variables of cancers did not affect the PSQI Global Sleep Quality score. The use of the mediation model also provides evidence that quality of sleep, quality of life, pain, and opioids are strictly correlated each other.
