Live concerts reduce cancer inpatients' anxiety.

In Italy a new experience of music medicine called "The Music Givers" is spreading among Oncology Units; it aims to organise weekly live concerts (length 45-60 min) followed by a buffet. Purpose of the present study is to evaluate the effect of the format of The Music Givers on cancer in-patients' anxiety. State-Trait Anxiety Inventory (STAI-Y) was administered to 111 in-patients before and after the concerts. After the concerts we observed a 3.87 point decrease in state anxiety (p < .001) and statistically significant differences in most of the domains assessed by STAI-Y. These results invite a reflection on the importance of offering to inpatients events such as live music concerts, in order to improve their psychological condition during hospitalisation.

Use of the Needs Evaluation Questionnaire with cancer outpatients.

PURPOSE: The Needs Evaluation Questionnaire (NEQ) is a self-administered instrument with 23 dichotomous items that is used both in oncology clinical practice and in research. It was originally developed for use in setting of hospitalization. The aim of the present study was to assess the factor structure of the NEQ in an outpatient oncology sample and to compare the unmet needs of inpatients and outpatients in the Italian context. METHODS: In 6 Italian oncology departments, 783 patients completed the NEQ. Patients included in the study had different primary tumor sites and were in different phases of the disease and care process. There were 195 inpatients and 588 outpatients total. RESULTS: Confirmatory factor analysis (CFA) showed that, with outpatients, the NEQ retained the distribution of the items in five main areas previously described with inpatients. Cancer outpatients expressed high percentages of unmet needs primarily concerning "material needs" and "needs for psycho-emotional support." Our survey also suggested that, in addition to the 23 original items, four new items could be tested for specific use with outpatients. CONCLUSIONS: Our findings highlight the importance of establishing routine assessment of unmet needs also in clinical oncology settings different from wards-such as day hospitals, ambulatory rehabilitation, or follow-up ambulatory care-where, at least in the Italian context, the rate of unmet needs is currently considerably high. The NEQ could be an effective tool for this assessment.

Complementary needs behind complementary therapies in cancer patients.

OBJECTIVE: Although many studies indicate that the use of complementary and alternative medicine by cancer patients is common and widespread, few studies have focused on unmet needs of patients using complementary therapies (CTs). The aim of the present study was to evaluate, through a quantitative approach, possible associations between the use of CTs and the presence of specific unmet needs in cancer patients. METHODS: In six Italian oncology departments, 783 patients were interviewed about CTs use and completed the Needs Evaluation Questionnaire. Patients included in the study had different primary tumor sites and were in different phases of the disease and care process. RESULTS: At the time of the survey, 38.3% of patients were using one or more types of CTs. According to Needs Evaluation Questionnaire, the use of CTs was associated (p < .05) with the need to be more involved in therapeutic choices (40% vs. 31.7%), the need to have a better dialogue with clinicians (44.4% vs. 37.2%), and the need to have more economic-insurance information in relation to their illness (46.1% vs. 36.4%). Statistical significance was confirmed with multivariable analysis for the last two items, whereas three more needs were associated with the use of CTs after adjustment: to receive more explanation on treatments (46.8% vs. 41.0%), to receive more comprehensible information (38% vs. 31.9%), and to receive more attention from nurses (16% vs. 12.1%). CONCLUSIONS: Our study shows interesting differences regarding perceived needs between cancer patients who use and who do not use CTs. Unmet needs that are more expressed in CTs users should be known and, when possible, could be taken into account to improve both psychosocial interventions in the context of conventional care process and the quality of the relationship between patient and medical and nursing staff.

Fully automated solid-phase microextraction-fast gas chromatography-mass spectrometry method using a new ionic liquid column for high-throughput analysis of sarcosine and N-ethylglycine in human urine and urinary sediments.

A fully automated, non invasive, rapid and high-throughput method for the direct determination of sarcosine and N-ethylglycine in urine and urinary sediments using hexyl chloroformate derivatization followed by direct immersion solid-phase micro extraction and fast gas chromatography-mass spectrometric analysis was developed and validated. The use of a new ionic liquid narrow bore column, as well as the automation and miniaturization of the preparation procedure by a customized configuration of the utilized XYZ robotic system, allowed a friendly use of the GC apparatus achieving a quantitation limit of 0.06 µg L(-1) for sarcosine, good repeatability with CV always lower than 7% and reduced analysis times useful for point-of-care testing. The method was then applied for the analysis of 56 samples of urine and urinary sediments in healthy subjects, in those with benign prostatic hypertrophy and in patients with clinically localized prostate cancer. The results obtained showed that the medians of sarcosine/creatinine in urine were 103, 137 and 267 µg g(-1) respectively, thus assessing the potential use of sarcosine as urinary biomarker for prostate cancer detection. The highest values of sensitivity (79%) and specificity (87%) were obtained in correspondence of a cut-off value of 179 µg sarcosine(g creatinine)(-1), thus by using this cut-off threshold, sarcosine was significantly associated with the presence of cancer (p<0.0001). Finally, ROC analyses proved that the discrimination between clinically localized prostate cancer and patients without evidence of tumor is significantly correlated with sarcosine.

Locating industrial VOC sources with aircraft observations.

Observation and characterization of environmental pollution, focussing on Volatile Organic Compounds (VOCs), in a high-risk industrial area, are particularly important in order to provide indications on a safe level of exposure, indicate eventual priorities and advise on policy interventions. The aim of this study is to use the Solid Phase Micro Extraction (SPME) method to measure VOCs, directly coupled with atmospheric measurements taken on a small aircraft environmental platform, to evaluate and locate the presence of VOC emission sources in the Marghera industrial area. Lab analysis of collected SPME fibres and subsequent analysis of mass spectrum and chromatograms in Scan Mode allowed the detection of a wide range of VOCs. The combination of this information during the monitoring campaign allowed a model (Gaussian Plume) to be implemented that estimates the localization of emission sources on the ground.

Assessment of psychological distress in cancer patients: a pivotal role for clinical interview.

OBJECTIVE: The evaluation of psychological distress in cancer patients recently entered oncologic clinical practice. The objective of this study was to evaluate the role of clinical interview within psycho-oncologic assessment. METHODS: Questionnaires assessing distress (PDI), psychopathology (MHQ, HADS) and needs (NEQ) and a subsequent clinical interview were proposed to 320 consecutive inpatients from the Oncology Department of Careggi Hospital in Florence. RESULTS: The clinical interview made it possible to evaluate a significant percentage of patients (30%) who did not fill in questionnaires and to detect the presence of distress in 39 (13.7%) patients who would not have received a diagnosis in a protocol for the assessment of distress based only on questionnaires. It also provided the possibility to ask for help or to receive clinical support to a high percentage of patients (44.1%) who had not requested to speak to a psychologist through the questionnaires (NEQ). Moreover, 25% of patients who received prolonged clinical support had a low score in tests detecting distress, indicating that the opportunity for therapeutic support can emerge during a clinical interview, also in the absence of relevant symptoms detected by questionnaires. CONCLUSIONS: The use of more than one questionnaire in the assessment of distress and psychopathology is associated with reduced compliance and redundant information. On the other hand, clinical interview has a pivotal role in clinical evaluation and access to psychological support. We conclude that optimal efficacy of programs assessing distress in cancer patients is reached when a single questionnaire evaluating distress is associated with a clinical interview.

Overexpression of Bcl-2 by activated human hepatic stellate cells: resistance to apoptosis as a mechanism of progressive hepatic fibrogenesis in humans.

BACKGROUND AND AIMS: Myofibroblast-like cells, originating from activation of hepatic stellate cells (HSC/MFs), play a key role in liver fibrosis, a potentially reversible process that may rely on induction of HSC/MFs apoptosis. While this possibility has been shown in cultured rat HSC, very limited data are currently available for human HSC/MFs. METHODS: Cultured human HSC/MFs were exposed to several proapoptotic stimuli, including those known to induce apoptosis in rat HSC/MFs, and induction of cell death and related mechanisms were investigated using morphology, molecular biology, and biochemical techniques. RESULTS: In this study we report that fully activated human HSC/MFs did not undergo spontaneous apoptosis and survived to prolonged serum deprivation, Fas activation, or exposure to nerve growth factor, tumour necrosis factor alpha (TNF-alpha), oxidative stress mediators, doxorubicin, and etoposide. Induction of caspase dependent, mitochondria driven apoptosis in HSC/MFs was observed only when protein synthesis or transcription were inhibited. Importantly, the process of HSC activation was accompanied by changes in expression of a set of genes involved in apoptosis control. In particular, activated human HSC/MFs in culture overexpressed Bcl-2. The role of Bcl-2 was crucial as Bcl-2 silenced cells became susceptible to TNF-alpha induced apoptosis. Finally, Bcl-2 was markedly expressed in HSC/MFs present in liver tissue obtained from patients with hepatitis C virus related cirrhosis. CONCLUSIONS: Human activated HSC/MFs are resistant to most proapoptotic stimuli due to Bcl-2 overexpression and this feature may play a key role in the progression of fibrosis in chronic liver diseases.

Agonist-specific regulation of monocyte chemoattractant protein-1 expression by cyclooxygenase metabolites in hepatic stellate cells.

Activated hepatic stellate cells (HSC) regulate the liver "wound-healing" response through expression of chemokines, including monocyte chemoattractant protein-1 (MCP-1), which participate in the formation of the inflammatory infiltrate during liver injury. Cyclooxygenase (COX) catalyzes the conversion of arachidonic acid into prostaglandins, which may contribute to the inflammatory response. In this study, we investigated the effects of COX inhibitors on the expression of MCP-1 in cultured HSC. Pretreatment of HSC with nonspecific COX inhibitors such as indomethacin or ibuprofen markedly reduced the expression of MCP-1 caused by exposure to tumor necrosis factor alpha (TNF-alpha) or interleukin-1alpha (IL-1alpha). NS-398, a specific COX-2 inhibitor, also resulted in a dose-dependent inhibition of MCP-1 gene and protein expression. These effects were dependent on reduced MCP-1 transcription, as established using a reporter plasmid. In contrast, the up-regulation of MCP-1 expression caused by interferon gamma (IFN-gamma) was not sensitive to COX inhibitors. Quiescent HSC did not show detectable expression of COX-2, which became evident after activation in culture, and while TNF-alpha and IL-1alpha markedly increased the expression of COX-2, IFN-gamma did not have any effects. Pretreatment of HSC with the stable cyclic adenosine monophosphate (cAMP) analog, 8-bromo cAMP, reverted the effects of the COX-2 inhibitor, but not of a nuclear factor-kappaB (NF-kappaB) inhibitor, demonstrating that prostaglandins modulate MCP-1 expression via production of cAMP. On the other hand, the action of NF-kappaB inhibitors was negligible in IFN-gamma-stimulated cells. These findings indicate that cross-talk between cytokines and a prostaglandin-cAMP pathway differentially regulates the proinflammatory potential of HSC, contributing to the modulation of liver tissue inflammation.

Signal transduction by the chemokine receptor CXCR3: activation of Ras/ERK, Src, and phosphatidylinositol 3-kinase/Akt controls cell migration and proliferation in human vascular pericytes.

Hepatic stellate cells (HSC) and glomerular mesangial cells (MC) are tissue-specific pericytes involved in tissue repair, a process that is regulated by members of the chemokine family. In this study, we explored the signal transduction pathways activated by the chemokine receptor CXCR3 in vascular pericytes. In HSC, interaction of CXCR3 with its ligands resulted in increased chemotaxis and activation of the Ras/ERK cascade. Activation of CXCR3 also stimulated Src phosphorylation and kinase activity and increased the activity of phosphatidylinositol 3-kinase and its downstream pathway, Akt. The increase in ERK activity was inhibited by genistein and PP1, but not by wortmannin, indicating that Src activation is necessary for the activation of the Ras/ERK pathway by CXCR3. Inhibition of ERK activation resulted in a decreased chemotactic and mitogenic effect of CXCR3 ligands. In MC, which respond to CXCR3 ligands with increased DNA synthesis, CXCR3 activation resulted in a biphasic stimulation of ERK activation, a pattern similar to the one observed in HSC exposed to platelet-derived growth factor, indicating that this type of response is related to the stimulation of cell proliferation. These data characterize CXCR3 signaling in pericytes and clarify the relevance of downstream pathways in the modulation of different biologic responses.

Ligands of peroxisome proliferator-activated receptor gamma modulate profibrogenic and proinflammatory actions in hepatic stellate cells.

BACKGROUND & AIMS: Proliferation and migration of hepatic stellate cells (HSCs) and expression of chemokines are involved in the pathogenesis of liver inflammation and fibrogenesis. Peroxisome proliferator-activated receptor (PPAR)-gamma is a receptor transcription factor that controls growth and differentiation in different tissues. We explored the effects of PPAR-gamma agonists on the biological actions of cultured human HSCs. METHODS: HSCs were isolated from normal human liver tissue and used in their myofibroblast-like phenotype or immediately after isolation. Activation of PPAR-gamma was induced with 15-deoxy-Delta(12, 14)-prostaglandin J(2) or with troglitazone. RESULTS: PPAR-gamma agonists dose-dependently inhibited HSC proliferation and chemotaxis induced by platelet-derived growth factor. This effect was independent of changes in postreceptor signaling or expression of c-fos and c-myc and was associated with inhibition of cell cycle progression beyond the G(1) phase. Activation of PPAR-gamma also resulted in a complete inhibition of the expression of monocyte chemotactic protein 1 at the gene and protein levels. Comparison of quiescent and culture-activated HSCs revealed a marked decrease in PPAR-gamma expression in activated cells. CONCLUSIONS: Activation of PPAR-gamma modulates profibrogenic and proinflammatory actions in HSCs. Reduced PPAR-gamma expression may contribute to confer an activated phenotype to HSCs.
