The role of the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke (GLOBE-3S) in the prevention of stroke-associated pneumonia (SAP).

BACKGROUND AND PURPOSE: Stroke-associated pneumonia (SAP) affects 10 to 38% of patients in the acute phase of stroke. Stroke patients diagnosed with dysphagia have an 11-fold higher risk of developing SAP. Thus, identifying dysphagic patients through a highly accurate screening tool might be crucial in reducing the incidence of SAP. We present a case-control study designed to evaluate efficacy in reducing the risk of SAP between two swallowing screening tools, the classic water swallow test (WST) and a recently validated tool such as the GLOBE-3S (the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke), which is a highly sensitive swallowing screening tool particularly accurate in detecting silent aspiration as well. METHODS: We analyzed the occurrence of dysphagia in 100 acute stroke patients distributed in two groups: half were screened with WST and the other half with GLOBE-3S. RESULTS: Dysphagia was diagnosed in 28 patients. The main result is that, among patients who passed the dysphagia screenings, none of those screened with the GLOBE-3S method developed pneumonia compared to 31.82% in the WST group. Discriminant function analysis (DFA) showed that NIH Stroke Scale (NIHSS) score and the dysphagia screening method (i.e., GLOBE-3S vs. WST) were the two main factors in the SAP's predicting model and the only significant ones per se. CONCLUSIONS: The new GLOBE-3S screening test can reduce the risk of SAP compared to WST.

Sapienza Global Bedside Evaluation of Swallowing after Stroke: the GLOBE-3S study.

BACKGROUND AND PURPOSE: Dysphagia occurs in up to 50% of all patients with acute stroke. There is debate regarding which is the most effective screening tool in identifying aspiration in patients with acute stroke. We assessed the accuracy of the Sapienza Global Bedside Evaluation of Swallowing after Stroke (GLOBE-3S), which combines the Toronto Bedside Swallowing Screening Test (TOR-BSST©) with oxygen desaturation and laryngeal elevation measurement during swallowing. METHODS: We prospectively enrolled consecutive patients with stroke within 72 h of symptom onset. All patients with stroke firstly underwent a standard neurological examination, then the GLOBE-3S evaluation and finally the fiberoptic endoscopic evaluation of swallowing (FEES). Two different assessors, a neurologist and a speech pathologist, blind to both the clinical data and each other's evaluation, administered the GLOBE-3S and FEES examination. We assessed the accuracy of the GLOBE-3S in detecting post-stroke swallow impairment with aspiration using the FEES as the standard. RESULTS: We enrolled 50 patients with acute stroke, 28 of whom (56%) had swallowing impairment with aspiration at FEES evaluation. A total of 33 patients (66%) failed the GLOBE-3S evaluation. The GLOBE-3S reached a sensitivity of 100% and a specificity of 77.3% (negative predictive value, 100%; positive likelihood ratio, 4.34). The median time required for the GLOBE-3S to be performed was 297 s. CONCLUSIONS: GLOBE-3S is quick to perform at the bedside and can accurately identify aspiration in patients with acute stroke. By including the measurement of laryngeal elevation and monitoring of oxygen desaturation, it could represent a highly sensitive instrument to avoid the misdiagnosis of silent aspirators.

A history of meniscal surgery: from ancient times to the twenty-first century.

The science and surgery of the meniscus have evolved significantly over time. Surgeons and scientists always enjoy looking forward to novel therapies. However, as part of the ongoing effort at optimizing interventions and outcomes, it may also be useful to reflect on important milestones from the past. The aim of the present manuscript was to explore the history of meniscal surgery across the ages, from ancient times to the twenty-first century. Herein, some of the investigations of the pioneers in orthopaedics are described, to underline how their work has influenced the management of the injured meniscus in modern times.

Screening for predictors of adverse outcome in onco-geriatric surgical patients: A multicenter prospective cohort study.

AIMS: The aim of this study was to investigate the predictive ability of screening tools regarding the occurrence of major postoperative complications in onco-geriatric surgical patients and to propose a scoring system. METHODS: 328 patients ≥ 70 years undergoing surgery for solid tumors were prospectively recruited. Preoperatively, twelve screening tools were administered. Primary endpoint was the incidence of major complications within 30 days. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression. A scoring system was derived from multivariate logistic regression analysis. The area under the receiver operating characteristic curve (AUC) was applied to evaluate model performance. RESULTS: At a median age of 76 years, 61 patients (18.6%) experienced major complications. In multivariate analysis, Timed Up and Go (TUG), ASA-classification and Nutritional Risk Screening (NRS) were predictors of major complications (TUG>20 OR 3.1, 95% CI 1.1-8.6; ASA ≥ 3 OR 2.8, 95% CI 1.2-6.3; NRS impaired OR 3.3, 95% CI 1.6-6.8). The scoring system, including TUG, ASA, NRS, gender and type of surgery, showed good accuracy (AUC: 0.81, 95% CI 0.75-0.86). The negative predictive value with a cut-off point >8 was 93.8% and the positive predictive value was 40.3%. CONCLUSIONS: A substantial number of patients experience major postoperative complications. TUG, ASA and NRS are screening tools predictive of the occurrence of major postoperative complications and, together with gender and type of surgery, compose a good scoring system.

Gaspare Tagliacozzi, pioneer of plastic surgery and the spread of his technique throughout Europe in "De Curtorum Chirurgia per Insitionem".

Gaspare Tagliacozzi's innovative surgical technique, which consisted of reconstructing parts of the face by grafting, was masterfully described in the work that made him famous, "De Curtorum Chirurgia per Insitionem." It was published by Gaspare Bindoni the Younger in 1597 in Venice, who was granted the exclusive right to print it by the Senate. However, in the same year in Venice Roberto Meietti published an unauthorized edition; nevertheless, this edition was soon discovered. The great demand for the text even abroad was soon testified by a 3rd edition published in Frankfurt in 1598, similar to the Bindoni edition but in another format and with a different title. This has caused confusion among bibliographers and Authors. Two centuries later, in 1831 in Berlin, a 4th edition was printed, thus suggesting renewed interest in rhinoplasty procedures, which surgeons Van Graefe and Dieffenbach promoted in Germany. However, few people know that the integral text of Tagliacozzi's De Curtorum was also published by Jacques Manget in his "Bibliotheca Chirurgica," printed in Venice in 1721. The name of the illustrator of the three fourteenth-century editions, whose illustrations in the text are compared, is not known. Instead the name of the artist, Tiburzio Passerotti, who painted Tagliacozzi's portrait holding his De Curtorum open at the ninth woodcut shortly before it was printed, is well known. The impact of Tagliacozzi's technique on modern surgery is supported by experience of the last century as well as recent years, mostly in musculoskeletal oncology reconstruction.

Handgrip strength predicts survival and is associated with markers of clinical and functional outcomes in advanced cancer patients.

PURPOSE: Handgrip strength (HGS) has been shown to predict survival and is associated with changes in body composition, nutritional status, inflammation, and functional ability in several chronic disease conditions. Whether similar relationships exist between HGS and clinical outcomes in patients with advanced cancer are currently unknown. We evaluated the association between HGS and survival as well as several key markers of body composition (e.g., sarcopenia), subjective performance measures (e.g., quality of life), and muscle strength (e.g., isokinetic torque of the quadriceps) in patients with advanced forms of non-small cell lung and gastrointestinal cancers. METHODS: A consecutive cohort of 203 patients with advanced cancer was enrolled and categorized into three HGS percentiles (e.g., ≥50th, 25th, and ≤10th) according to published normative values. Multivariate regression analyses were used to test for independent associations between HGS and survival, sarcopenia, quality of life (QoL), and lower extremity muscle strength as well as key biological markers (e.g., hemoglobin, albumin, and C-reactive protein) while controlling for age, gender, cancer diagnosis, treatment (chemotherapy/radiotherapy), medications, and time from diagnosis to assessment. RESULTS: When compared to HGS ≥50th, patients in the HGS ≤10th percentile had lower BMI (B, -2.5 kg/m(2); 95% CI, -4.5 to -0.45), shorter survival (hazard ratio, 3.2; 2.0-5.1), lower hemoglobin (-19.70 g/L; -27.28 to -12.13) and albumin (-4.99 g/L; -7.85 to -2.13), greater occurrence of sarcopenia (odds ratio, 9.53; 1.95-46.55), lower isokinetic torque of the quadriceps at both 60°/s (-30.6 Nm; -57.9 to -3.3) and 120°/s (-25.1 Nm; -46.4 to -3.7), lower QoL (-1.6 on McGill Quality of Life Questionnaire scale; -2.5 to -0.6), higher levels of fatigue (18.8 on Brief Fatigue Inventory scale; 4.7 -32.9), poorer performance status (0.75 on Eastern Cooperative Oncology Group Performance Status scale; 0.34-1.15), lower fat mass (-7.4 kg; -14.4 to -0.5), and lower lean body mass (-6.5 kg; -10.3 to -2.8). CONCLUSIONS: HGS is independently associated with survival and important biological, functional, and quality of life characteristics in advanced cancer patients. Patients presenting with very low percentiles with respect to their handgrip assessment may require timely referral to supportive and/or palliative care services.

European AIDS Clinical Society (EACS) guidelines on the prevention and management of metabolic diseases in HIV.

BACKGROUND: Metabolic diseases are frequently observed in HIV-infected persons and, as the risk of contracting these diseases is age-related, their prevalence will increase in the future as a consequence of the benefits of antiretroviral therapy (ART). SUMMARY OF GUIDELINES: All HIV-infected persons should be screened at regular intervals for a history of metabolic disease, dyslipidaemia, diabetes mellitus, hypertension and alteration of body composition; cardiovascular risk and renal function should also be assessed. Efforts to prevent cardiovascular disease will vary in intensity depending on an individual's absolute risk of ischaemic heart disease and should be comprehensive in nature. Lifestyle interventions should focus on counselling to stop smoking, modify diet and take regular exercise. A healthy diet, exercise and maintaining normal body weight tend to reduce dyslipidaemia; if not effective, a change of ART should be considered, followed by use of lipid-lowering medication in high-risk patients. A pre-emptive switch from thymidine analogues is recommended to reduce the risk of development or progression of lipoatrophy. Intra-abdominal fat accumulation is best managed by exercise and diet. Prevention and management of type 2 diabetes mellitus and hypertension follow guidelines used in the general population. When using medical interventions to prevent and/or treat metabolic disease(s), impairment of the efficacy of ART should be avoided by considering the possibility of pharmacokinetic interactions and compromised adherence. Specialists in HIV and specialists in metabolic diseases should consult each other, in particular in difficult-to-treat cases. CONCLUSION: Multiple and relatively simple approaches exist to prevent metabolic diseases in HIV-infected persons; priority should be given to patients at high risk of contracting these diseases.

Metabolic modulation induced by chronic hypoxia in rats using a comparative proteomic analysis of skeletal muscle tissue.

Hypoxia-induced changes of rat skeletal muscle were investigated by two-dimensional difference in-gel electrophoresis (2D-DIGE) and mass spectrometry. The results indicated that proteins involved in the TCA cycle, ATP production, and electron transport are down-regulated, whereas glycolytic enzymes and deaminases involved in ATP and AMP production were up-regulated. Up-regulation of the hypoxia markers hypoxia inducible factor 1 (HIF-1alpha) and pyruvate dehydrogenase kinase 1 (PDK1) was also observed, suggesting that in vivo adaptation to hypoxia requires an active metabolic switch. The kinase protein, mammalian target of rapamycin (mTOR), which has been implicated in the regulation of protein synthesis in hypoxia, appears unchanged, suggesting that its activity, in this system, is not controlled by oxygen partial pressure.

Mitochondria in the pathogenesis of lipodystrophy induced by anti-HIV antiretroviral drugs: actors or bystanders?

Effective therapies are now available that can stop the progression of HIV infection and significantly delay the onset of AIDS. The "highly active antiretroviral therapy" (HAART) is a combination of potent antiretroviral drugs such as viral protease inhibitors or nucleoside-analogue reverse-transcriptase inhibitors, that has a variety of serious side effects, including lipodystrophy, a pathology characterized by accumulation of visceral fat, breast adiposity, cervical fat-pads, hyperlipidemia, insulin resistance as well as fat wasting in face and limbs. There is still an open debate that concerns the precise responsibility of HAART as well as metabolic pathways and mechanisms that are involved in the onset of lipodystrophy. The similarities with multiple symmetric lipomatosis (MSL), in which mitochondria impairment plays a crucial role, lead to the hypothesis that drug-induced damages to mitochondrial DNA are able to alter mitochondria functionality to an extent that is similar to what occurs in MSL. In addition, several evidences indicate that HAART is also linked to a deregulated production of tumour necrosis factor-alpha, which uses mitochondria as intracellular targets. In this paper, we review data concerning the role of mitochondria in the pathogenesis of lipodystrophy, and advance a unifying hypothesis involving either direct or indirect effects of the drugs employed during HAART.

Markers of cell death-activation in lymphocytes of vertically HIV-infected children naive to highly active antiretroviral therapy: the role of age.

BACKGROUND: Apoptosis plays a major role in depleting CD4(+) lymphocytes during infection with HIV-1. Few data exist on its role during HIV infection of children. Sensitivity of peripheral blood lymphocytes (PBLs) to apoptotic stimuli and the importance of the patient's age remain unclear. OBJECTIVES: We sought to analyze the following: (1) markers of cell death-activation (CD95, CD45 isoforms, and CD28) in PBLs from vertically HIV-infected children of different ages before highly active antiretroviral therapy; (2) changes in other PBL populations; (3) PBL sensitivity to cell death and mitochondrial damages; and (4) role of age during progression of infection. METHODS: Cell culture techniques and flow cytometry were used to analyze surface antigens, PBL susceptibility to apoptosis, or PBL susceptibility to change of mitochondrial membrane potential. RESULTS: Donor age had a strong negative correlation with numbers of CD4(+) and CD8(+) T cells. Virgin T lymphocyte (CD45RA(+), CD95(-)) levels and those of CD95(+) cells showed no correlation with the children's clinical status but did show a correlation with patient age. CD28(-) T lymphocytes were markedly augmented in HIV-infected children but were unrelated to stage of infection or age. A relevant decrease in B lymphocytes and an increase in natural killer cells were also found. Finally, PBLs from HIV-positive children had a marked tendency to undergo apoptosis and mitochondrial damage. CONCLUSION: Changes in PBL phenotype, increased expression of CD95, and high sensitivity to apoptosis suggest that a precocious aging of the immune system occurs in HIV-infected children.

Equianalgesic dose ratios for opioids. a critical review and proposals for long-term dosing.

Clinicians involved in the opioid pharmacotherapy of cancer-related pain should be acquainted with a variety of opioids and be skilled in the selection of doses when the type of opioid or route of administration needs changing. The optimal dose should avoid under-dosing or overdosing, both associated with negative outcomes for the patient. Although equianalgesic dose tables are generally used to determine the new doses in these circumstances, the evidence to support the ratios indicated in these tables largely refers to the context of single dose administration. The applicability of these ratios to the setting of chronic opioid administration has been questioned. A systematic search of published literature from 1966 to September 1999 was conducted to critically appraise the emerging evidence on equianalgesic dose ratios derived from studies of chronic opioid administration. There were six major findings: 1) there exists a general paucity of data related to long-term dosing and studies are heterogeneous in nature; 2) the ratios exhibit extremely wide ranges; 3) methadone is more potent than previously appreciated; 4) the ratios related to methadone are highly correlated with the dose of the previous opioid; 5) the ratio may change according to the direction the opioid switch; and 6) discrepancies exist with respect to both oxycodone and fentanyl. Overall, these findings have important clinical implications for clinicians and warrant consideration in the potential revision of current tables. The complexity of the clinical context in which many switches occur must be recognized and also appreciated in the design of future studies.

Multidisciplinary symptom control clinic in a cancer center: a retrospective study.

Our objective in this study was to review the characteristics, symptom intensity and satisfaction of patients referred to a half-day symptom control clinic (SCC) for advanced cancer patients. This was a retrospective study. The setting was a multidisciplinary symptom control clinic in a cancer centre. Those taking part were 166 consecutive advanced cancer patients referred to the half-day multidisciplinary SCC because of symptom distress. Patients referred to the clinic were assessed in a private room by a physician, a nurse, a pharmacist, a psychologist, and social, rehabilitation, nutrition, respiratory and pastoral care workers. Symptom distress (multiple visual analogue scales), cognition, and CAGE (alcoholism) were determined. Recommendations were given to the patient and sent to the oncologist, family physician and home care nurse. For 110 patients a second assessment was carried out 1 week later, and 64 patients underwent a telephone assessment 2 weeks after the second visit. Symptom intensity was determined during initial and follow-up visits, as well as during two follow-up telephone assessments. In addition, demographics and patient satisfaction with the SCC were determined. Overall symptom distress, depression, anxiety and sensation of wellbeing improved significantly from the first (n = 166) to the second clinic visit (n = 110). Further significant improvement was observed in overall symptom distress, pain, anxiety, sense of wellbeing and depression at the 2- (n = 64) and 4-week (n = 38) telephone follow-up assessments. Mean satisfaction with the SCC (0-10) was 7.7 +/- 2. Our findings suggest that the work of the SCC results in long-term effectiveness in symptom control and high levels of patient satisfaction. The SCC allows for better integration of care between a cancer center and community-based physicians and nurses. It also allows patients access to multiple disciplines that are not available outside tertiary centers.

Survival prediction in terminal cancer patients: a systematic review of the medical literature.

The clinical significance of studies on survival predictors in terminal cancer patients is hindered by both methodological limitations and the difficulty of finding common predictors for all final events in cancer related deaths. To evaluate the published medical literature concerned with the survival of patients with terminal cancer and identify potential prognostic factors, major electronic databases including MEDLINE (1966-), CANCERLIT (1983-) and EMBASE (1988-) were searched up to September 1999. Studies were included in our review if published in English, were cohort studies, addressed the identification of clinical prognostic factors for survival and looked at samples with median survival of < or = 3 months. Data extracted from selected papers included: sample size, median survival, type of study, sampling frame, cohort type, type of statistical analysis (univariate or multivariate), choice of models and underlying assumptions, predictors examined and their reported level of statistical significance. A total of 24 studies were found and reviewed. On the basis of these studies, performance status and the presence of cognitive failure, weight loss, dysphagia, anorexia and dyspnoea appear to be independent survival predictors in this population. Clinical estimation of survival by the treating physician appeared independently associated with survival but the magnitude of the association generally appeared small. Clinical predictions should be considered as one of many criteria, rather than as a unique criterion by which to choose therapeutic interventions or health care programmes for terminally ill cancer patients. The use of convenient samples as opposed to more representative inception cohorts, the inclusion of different variables in the statistical analyses and inappropriate statistical methods appear to be major limitations of the reviewed literature. Methodological improvements in the design and conduction of future studies may reduce the prognostic uncertainty in this population.

Screening for the beta-39 mutation in thalassemia by capillary electrophoresis in free solution in strongly acidic, isoelectric buffers.

A novel method is reported for screening for point mutations in genomic DNA: free-zone capillary electrophoresis in very acidic buffers. This method exploits the charge difference among the four different bases (C, T, A, G) in a pH window between 2.5 and 3.5, where the four titration curves fan out. The method is applied to the detection of the beta-39 missense mutation in the beta-globin gene in thalassemias. A 60-mer fragment straddling the mutation site has been amplified. In an isoelectric buffer (iminodiacetic acid) of pH 3.3, partial resolution between the wild type and mutated strands is obtained. In a pH 3.0 phosphate buffer, baseline resolution is achieved between the two strands in a heterozygous individual. Due to the short size of the amplified fragment, this method can only be applied to routine screening for known mutations because resolution was lost in a fragment 100 bases long.

Single-strand conformation polymorphism analysis by capillary zone electrophoresis in neutral pH buffer.

Sensitivity of single-strand conformation polymorphism (SSCP) analysis of polymerase chain reaction (PCR) products was reported to be lower in capillary zone electrophoresis (CZE) compared to conventional slab gel electrophoresis. We examined the effects of buffer ion type, pH, and temperature in an attempt to improve the mutation detectability in the SSCP-CZE mode. It was noted that, by utilizing short-chain polyacrylamide as sieving media while simultaneously lowering the temperature, there was no improvement of conformer detectability. On the contrary, there was a large increment in conformers' resolution by running samples in a lower-pH buffer system. The effects of different buffering ions and pH values were investigated. By using a new buffer system, consisting of 35 mM 2-(N-morpholino)propanesulfonic acid (MES), 30 mM tris(hydroxymethyl)aminomethane (Tris), 1 mM ethylene diaminetetraacetic acid (EDTA), pH 6.8, and keeping constant all the other conditions, such as temperature, sieving, applied voltage, capillary length, and inner diameter (ID), there was a remarkable improvement in resolution and the sensitivity became comparable to that of slab gel systems.

Clinical survival predictors in patients with advanced cancer.

BACKGROUND: The clinical and epidemiological relevance of different prognostic factors for survival in patients with advanced or terminal cancer remains controversial. PURPOSES: To establish the survival of patients with cancer after diagnosis of terminal disease and to determine the predictors of survival. METHODS: An inception cohort of 227 consecutive patients aged 18 years or older with terminal cancer of the lung, breast, and gastrointestinal tract were observed from July 1, 1996, through December 31, 1998. Tumor- and treatment-specific, clinical, laboratory, demographic, and socioeconomic variables were recorded at baseline. The relationships between these characteristics and survival time were examined using univariate Kaplan-Meier and multivariate Cox regression analyses. RESULTS: At the time of data analysis, 208 patients (91.6%) had died; the overall median survival for the sample was 15.3 weeks. Shorter survival was independently associated (P< or =.05) with a primary tumor of the lung (vs breast and gastrointestinal tract combined), liver metastases, moderate to-severe comorbidity levels (vs absent-to-mild levels), weight loss of greater than 8.1 kg in the previous 6 months, serum albumin levels of less than 35 g/L, lymphocyte counts of less than 1 X 10(9)/L, serum lactate dehydrogenase levels of greater than 618 U/L, and clinical estimation of survival by the treating physician of less than 2 months (vs 2-6 and >6 months). Performance status, symptoms other than nausea and vomiting, tumor burden, and socioeconomic characteristics such as social support and education and income levels did not appear to be independently associated with survival after adjusting for the effect of prognostic factors. CONCLUSIONS: Simple clinical and laboratory assessments are useful aids in the prediction of survival in patients with solid malignant neoplasms at the onset of terminal stages. Methodological improvements in the design and implementation of survival studies may reduce prognostic uncertainty and ultimately provide better care for the terminally ill patients and their families.

Blount's disease.

Out of a total of 40 patients affected with Blount's disease treated at the Pediatric Orthopaedic Division of the Rizzoli Orthopaedic Institute between 1965 and 1996, 29 were affected with the infantile type, and 11 with the adolescent type. In the group affected with infantile Blount's disease, the mean age was 5.5 years, 11 were bilateral, for a total of 40 limbs affected, with a mean TMD angle of 24 degrees. All of the patients were treated by valgus osteotomy obtaining a percentage of poor results (insufficient correction or recurrence) equal to 25% according to Schoenecker's criteria. Mean follow-up was 3.6 years. In the group affected with adolescent Blount's disease, mean age was 12.6 years, the affection was always monolateral, the mean TMD angle was 15 degrees. All of the patients except 1 were treated by valgus osteotomy with elevation, and the results were constantly favorable. Mean follow-up was 2 years. The authors believe that the type of osteotomy used must be modulated based on the anatomopathologic findings of compromise in the proximal tibial metaepiphysis.

The relative accuracy of the clinical estimation of the duration of life for patients with end of life cancer.

BACKGROUND: Although the prediction of the duration of life of patients with end of life cancer most often relies on the clinical estimation of survival (CES) made by the treating physician, the accuracy and practical value of CES remains controversial. METHODS: The authors prospectively evaluated the accuracy of CES in an inception and population-based cohort of 233 cancer patients who were seen at the onset of their terminal phase. They also systematically reviewed the literature on CES in advanced or end-stage cancer patients in MEDLINE, CANCERLIT, and EMBASE data bases, using two search strategies developed by a research librarian. RESULTS: CES had low sensitivity in detecting patients who died within shorter time frames (< or =2 months), and a tendency to overestimate survival was noted. A moderate correlation was observed between actual survival (AS) and CES (Pearson correlation coefficient = 0.47, intraclass correlation coefficient = 0.46, weighted kappa coefficient = 0.42). CONCLUSIONS: Treating physicians appear to overestimate the duration of life of end of life ill cancer patients, particularly those patients who die early in the terminal phase and who may potentially benefit from earlier participation in palliative care programs. CES should be considered one of many criteria, rather than a unique criterion, by which to choose therapeutic intervention or health care programs for patients in the end of life cancer phase.
