RESUMO

BACKGROUND: The Patient Reported Outcome for Fighting FInancial Toxicity (PROFFIT) questionnaire was developed to measure financial toxicity (FT) and identify its determinants. The aim of the present study was to confirm its validity in a prospective cohort of patients receiving anticancer treatment. PATIENTS AND METHODS: From March 2021 to July 2022, 221 patients were enrolled at 10 Italian centres. Selected items of the EORTC-QLQ-C30 questionnaire represented the anchors, specifically, question 28 (Q-28) on financial difficulties, and questions 29-30 measuring global health status/quality of life (HR-QOL). The study had 80% power to detect a 0.20 correlation coefficient (r) between anchors and PROFFIT-score (items 1-7, range 0-100, 100 indicating maximum FT) with bilateral alpha 0.05 and 80% power. Confirmatory factor analysis was conducted. FT determinants (items 8-16) were described. RESULTS: Median age of patients was 65 years, 116 (52.5%) were females, 96 (43.4%) had low education level. Confirmatory factor analysis confirmed goodness of fit of the PROFFIT-score. Significant partial correlation of PROFFIT-score was found with Q-28 (r = 0.51) and HR-QOL (r = -0.23). Mean (SD) PROFFIT-score at baseline was 36.5 (24.9); it was statistically significantly higher for patients living in South Italy, those with lower education level, those who were freelancer/unemployed at diagnosis and those who reported significant economic impact from the COVID-19 pandemic. Mean (SD) scores of determinants ranged from 17.6 (27.1) for item 14 (support from medical staff) to 49.0 (36.3) for item 10 (expenses for medicines or supplements). PROFFIT-score significantly increased with worsening response to determinants. CONCLUSIONS: External validation of PROFFIT-score in an independent sample of patients was successful. The instrument is now being used in clinical studies.

RESUMO

The Melanoma Independent Board (MIB) held its first conference from 21 to 22 October, 2013, in Rome, Italy. Like the MIB itself, the conference brought together specialists from all aspects of cancer care: doctors, patient associations, journalists, and representatives from local government, hospitals, and pharma to encourage an interdisciplinary discussion on the future of melanoma. It was hoped that the conference would be an opportunity for all participants to see and understand each other's points of view. In memoriam of melanoma pioneer Natalie Cascinelli, the conference focussed on innovation and sustainability as well as the latest drug developments.

RESUMO

BACKGROUND: The Internet has become a widely used resource for information on cancer and for support. As part of the EuroCancerComs project (www.eurocancercoms.eu), an intervention study has been designed. The study aims to help patients with cancer providing an Internet "space" where to find information about nutritional care. METHODS: The study consists of a randomized 6-month intervention. The website (www.supportonutrizionale.it) hosts a contents area, prepared according to guidelines and recommendations, a forum and a blog. Subjects have been randomly allocated in intervention (IG) and control group (CG). IG has a free access to the website and it is involved in live activities, discussions and examinations. CG receives the same information by e-mail, without having access to the website. Three questionnaires are used to evaluate the effectiveness of the approach, concerning quality of life (QoL), psychological status and nutrition facts. RESULTS: Since the study startup, 191 subjects have been screened, and 58 (30%) have been randomized. Participants in both groups are mainly females, married and have at least a high school education level. Participants experienced a high psychological distress for 27% of IG and 33% of CG considering the four classes of scores at the baseline. Regarding QoL, a low "role functioning" score for IG and "emotional functioning" and "social functioning" scores for both groups are reported, while "fatigue" and "nausea and vomiting" respectively for IG and CG are the worsened symptoms compared with reference values. Considering the nutrition facts questionnaire, subjects showed a medium-high score profile and the worst scale regards "Nutrition and cancer knowledge". From the beginning of the study, a total of 48 actions have been registered, including votes to contents, comments and forum messages. CONCLUSION: The Internet has made possible the new forms of interaction and knowledge, and it is likely to become essential to gain access to health information. The results of this randomized intervention may help in the evaluation of the efficacy of these interventions in cancer setting.

RESUMO

Dendritic cells (DCs) are able to orchestrate innate and acquired immunity and can activate and sustain a long-lasting anti-tumor immune response in vivo when used as anti-tumor cell therapy. The selection of the antigen and the choice of its formulation are key points in designing anti-cancer DC-based vaccines. Cell released vesicles/exosomes have been shown to transfer antigens, HLAI/peptide complexes and co-stimulatory molecules to recipient cells. In this study we describe the generation of an allogenic microvesicle cell factory in which the expression of a specific tumor antigen was combined to the expression of co-stimulatory and allogeneic molecules. The DG75 lymphoblastoid cell line was selected as microvesicle producer and transfected with ErbB2, as tumor antigen prototype. The shed microvesicles transferred antigenic components to recipient DCs, increasing their immunogenicity. DC pulsing resulted in cross-presentation of ErbB2 both in HLAI and HLAII compartments, and ErbB2-specific CD8+ T cells from cancer patients were activated by DCs pulsed with vesicle-bound ErbB2. The microvesicle cell factory proposed may represent a source of cell free immunogen to be used for DC-based cancer therapy.

RESUMO

We investigated the relationship between ritonavir concentrations and changes in lipids, vascular inflammation markers, CD36, and adipophilin expression in volunteers randomly assigned to groups receiving 100 mg of ritonavir once daily or twice daily. In both groups decreases in high-density lipoprotein (HDL) (6%, P = 0.010; and 10%, P < 0.001, respectively) and CD36 (14%, P = 0.012; and 16%, P = 0.006, respectively) and increases in the vascular inflammation marker sCD40L (12%, P = 0.008; 19%, P = 0.003, respectively) were seen. Increases in adipophilin (30%, P = 0.044) and triglycerides (32%, P = 0.044) were seen only in the group receiving ritonavir twice daily. The ritonavir concentration in the plasma correlated with changes in triglycerides, HDL, and adipophilin (r = 0.34, P = 0.030; r = 0.33, P = 0.040; and r = 0.4, P = 0.01, respectively).

RESUMO

Human immunodeficiency virus (HIV)-infected patients are at a significantly higher risk from coronary heart diseases (CHD) and myocardial infarction (MI) compared to gender- and age-matched non-infected individuals. Combination antiretroviral therapy (cART) has transformed a fatal illness into a chronic stable condition. However, cART induces metabolic abnormalities in HIV-infected patients, while its role in vascular atherosclerosis is still under investigation. The use of cART is linked to inflammation - a key mechanism in atherosclerotic progression and destabilisation that precedes clinical events like MI. There is evidence of visceral fat abnormal distribution in HIV infected patients, and inflammatory changes in HIV infected patients drive the initiation, progression and, ultimately, thrombotic clinical complications induced by atherosclerosis. Visceral adipose tissue, a virtual factory for manufacturing pro-inflammatory mediators, affects the liver function. The inflamed liver promotes the development of pro-atherogenic dyslipidaemia. Pro-inflammatory cytokines released by adipocytes travel to the skeletal muscles and other peripheral tissues, worsening insulin sensitivity and leading to hyperglycaemia. Increased high sensitivity C-reactive protein (hs-CRP) inflammatory marker is associated with endothelial dysfunction in HIV-infected patients. Increased levels of monocytic nuclear factor kappa-B (NFkappa-B), a master switch in the inflammatory cascade, are documented in patients with elevated hs-CRP levels. It can be assumed that, as a result of NFkappa-B activation, hs-CRP up-regulates cytokines that contribute to MI by recruiting leukocytes and promoting thrombosis. This review focuses on the association of HIV-infection, metabolic abnormalities and known mechanisms involved in inducing accelerated atherosclerosis and inflammation in HIV-infected patients, as well as the role of lipid lowering agents in potentially preventing CHD.

RESUMO

Cardiovascular diseases are the major cause of morbidity and mortality in the Western countries and their prevalence is increasing in developing world. The final biological evolution of atherosclerotic process, supporting development and progression of cardiovascular diseases, is thrombosis. In the most recent years several clinical trails have established that low molecular weight heparins play a major role in the area of prevention and treatment of arterial and venous thrombosis. It is now established, that low molecular weight heparins are efficacious and safe anticoagulant options for patients with deep vein thrombosis, pulmonary embolism, unstable angina and non-ST-segment elevation myocardial infarction. In addition, low molecular weight heparins play a major role to prevent thromboembolic events in patients with chronic diseases (e.g. due to cerebrovascular ischemic events, cancer) and in patients undergoing surgical interventions. Clinical trials have also shown that low molecular weight heparins might play a role in the treatment of patients with ST-segment elevation acute myocardial infarction, in the prevention of thrombotic events in patients with congestive heart failure, and in patients undergoing percutaneous coronary interventions. The combined use of low molecular weight heparins with fibrinolysis and other antithrombotic agents has been also studies in a number of clinical trials. This review summarises the results of the most recent clinical studies regarding the use of low molecular weight heparins in prevention and treatment of cardiovascular diseases.

RESUMO

The use of therapeutic apheresis in very low weight patients is generally thought to have limitations, because of possible severe adverse reactions, potential risk related to the extracorporeal procedure, due to the low weight of the young patients. A careful therapeutic approach using appropriate precautions, and also introducing modifications to the standard procedure, can minimise the risk without compromising the efficacy of the plasmapheresis. The aim of the study was to evaluate apheresis tolerance and acceptability in children [Artif. Organs. 21 (1997) 1126] and infants [J. Clin. Apheresis 5 (1989) 21] with inherited lipid metabolism disorder, familial hypercholesterolemia (FH), primary hyperlipoproteinemia (lipoprotein phenotype I), and acute leukemia, weighing on average 20.55 kg. One thousand one hundred twenty three aphereses were completed. Three types of apheresis were performed: leukapheresis, plasma exchange, dextran sulphate cellulose (DSC) low density lipoprotein (LDL)-apheresis. Three different types of continuous flow systems were used. Technical adaptation depending on patients blood volume, body mass index, hematocrit, type of system used, permitted us to perform complete aphereses, obtaining a high degree of tolerance and acceptability of the treatment. The use of plasmapheresis is regarded to be an extreme therapeutic measure in children. However, when the need for such treatment is undebatable, plasmapheresis must be done. A well-trained and experienced team can overcome the technical difficulties in order to complete the procedures without complications. The most frequently observed adverse effects are vascular relative access insufficiency (2.0%), and mild hypotension (2.0%).

RESUMO

BACKGROUND: It has been widely shown that the provision of adequate levels of information to patients does have a positive effect on quality of life by reducing anxiety and depression levels. The aim of this study was to show how Italian cancer patients rate the information they are given and whether the use of booklets and videotapes can improve their quality of life. PATIENTS AND METHODS: Cancer patients aged between 18 and 80 years who were about to receive their first chemotherapy course were randomized to fill in questionnaires on perceived quality of information, level of psychological distress, perceived severity and curability of the disease, and quality of life. The results were evaluated by means of statistical analyses. RESULTS: Out of 328 consecutive patients enrolled in 21 cancer centers, 86-93% considered the booklets either "very useful" or "useful". The videotape was regarded as "quite" or "much" more complete than the booklets (87%). According to 81%/87% of patients, the information that had been given had improved their knowledge of the disease/chemotherapy either "a lot" or "enough". CONCLUSIONS: The information patients receive from the oncologist was rated the highest, as long as they were devoted enough time. Booklets and videotapes can partially overcome the lack of oral information given by medical doctors. A better informed patient does help the oncologist save time.

RESUMO

The aim of the study was to evaluate any correlation between the circulating oestrogenic hormone 17beta-oestradiol and haemostatic factors in healthy postmenopausal women. In keeping with this objective, the correlations were evaluated irrespective of whether the source of the hormone was purely endogenous or exogenous as well. Accordingly, a univariate correlation adjusted for age, body mass index, and duration of menopause was determined in 42 healthy postmenopausal women aged 47-78 years, 19 of whom were self-reported users of hormone replacement therapy. The rest were self- reported never users. Serum 17beta-oestradiol exhibited a direct correlation with endogenous thrombin potential extrinsic pathway (R = 0.42, p = 0.01) and prothrombin fragments 1 and 2 (R = 0.37, p = 0.03) and an inverse correlation with antithrombin III (R = -0.36, p = 0.03) and alpha(2)-antiplasmin (R = -0.45, p = 0.005). The observations suggest an association of this hormone with net thrombin generation on the one hand and improved fibrinolysis on the other.

RESUMO

Epidemiological studies have shown an increase in acute myocardial infarctions or deaths due to myocardial infarction in colder weather; the mechanisms most likely involve increased blood levels of haemostatic risk factors, and increases in arterial blood pressure and heart rate. We studied the relationship between cold adaptation, haemostatic risk factors and haemodynamic variables. Cold adaptation was obtained by a programme of immersion of the whole body up to the neck in a water-filled bath, the temperature of which was gradually decreased from 22 degrees C to 14 degrees C, time of exposure being increased from 5 to 20 min over a period of 90 days. We studied 428 patients (44% men) and measured blood levels of fibrinogen, plasminogen activator inhibitor 1 (PAI-1), tissue plasminogen activator antigen (t-PA), plasma viscosity, von Willebrand factor, D-dimer and platelet count, both at baseline and after 90 days of daily immersion. There were significant reductions in von Willebrand factor (-3%; p < 0.001), and plasma viscosity (-3.0 s; p < 0.001), and a mild but significant increase in PAI-1 (+0.3 IU/ml; p = 0.02). The pressure rate product (systolic blood pressure x heart rate) was also significantly lower after cold adaptation (-310; p = 0.004). Cold adaptation, compared with exposure to cold weather, induces different haemodynamic responses and changes of blood levels of haemostatic risk factors.

RESUMO

We investigated whether chronic fatigue syndrome (CFS) patients have physical and/or cardiovascular de-conditioning, in 273 CFS patients and 72 healthy controls. We used laboratory tests to assess haematological, biochemical, endocrinological and immunological systems. The cardiovascular system was assessed by echocardiography and carotid echography. Body composition was determined by dual energy X-ray absorptiometry (DEXA). CFS patients had smaller left ventricular end systolic (p < 0.001) and diastolic (p = 0.008) dimensions but thinner posterior walls (p = 0.02) than corresponding values in healthy controls. Left ventricular mass was also reduced in CFS patients (p = 0.006). Both maximum (p < 0.001) and minimum (p < 0.008) diameter of the carotid artery were smaller in CFS patients. The laboratory screening tests showed significant differences in serum albumin (p = 0.05), phosphate (p = 0.02), HDL-cholesterol (p = 0.03), HDL:total cholesterol ratio (p = 0.01), triglycerides (p = 0.02), neutrophils (p = 0.01) and thyroid-stimulating hormone (p = 0.04) between CFS patients and controls. Male CFS patients had an increased percentage of fat mass compared with healthy male subjects (p = 0.02). This large group of CFS patients had evidence of physical and cardiovascular de-conditioning, suggesting that in these patients a graded exercise programme could lead to physical reconditioning and could increase their ability to perform physical activities.

RESUMO

Phosphate depletion is associated with neuromuscular dysfunction due to changes in mitochondrial respiration that result in a defect of intracellular oxidative metabolism. Phosphate diabetes causes phosphate depletion due to abnormal renal re-absorption of phosphate be the proximal renal tubule. Most of the symptoms presented by patients with phosphate diabetes such as myalgia, fatigue and mild depression, are also common in patients with chronic fatigue syndrome, but this differential diagnosis has not been considered. We investigated the possible association between chronic fatigue syndrome and phosphate diabetes in 87 patients who fulfilled the criteria for chronic fatigue syndrome. Control subjects were 37 volunteers, who explicitly denied fatigue and chronic illness on a screening questionnaire. Re-absorption of phosphate by the proximal renal tubule, phosphate clearance and renal threshold phosphate concentration were the main outcome measures in both groups. Of the 87 patients with chronic fatigue syndrome, nine also fulfilled the diagnostic criteria for phosphate diabetes. In conclusion, we report a previously undefined relationship between chronic fatigue syndrome and phosphate diabetes. Phosphate diabetes should be considered in differential diagnosis with chronic fatigue syndrome; further studies are needed to investigate the incidence of phosphate diabetes in patients with chronic fatigue syndrome and the possible beneficial effect of vitamin D and oral phosphate supplements.

RESUMO

Venous thromboembolism continues to be an important cause of death in hospitalized patients undergoing major elective surgery. A study of autopsy-proven pulmonary embolism in hospital patients showed that venous thromboembolism accounted for 10% of deaths and that recognition of non-fatal thromboembolism continues to be a problem. The incidence of deep vein thrombosis increases with ageing, the annual rate per 1000 being one to three for those aged between 65 and 69 years and from two to eight for those aged between 85 and 89 years. The introduction of low-molecular-weight heparins has resulted in important changes in the management and prophylaxis of venous thromboembolism. Low-molecular-weight heparin preparations reduce the overall incidence of deep vein thrombosis in general surgery by at least 70%. Furthermore, the effect of low-molecular-weight heparin against pulmonary embolism is at least as great as that of low-dose unfractionated heparin. The incidence of serious and minor haemorrhagic events with low-molecular-weight heparin is similar to that with low-dose unfractionated heparin. Prophylaxis is started pre-operatively, and the usual duration for the post-operative period has been 7 days, or until the patient is discharged from the hospital. In conclusion, low-molecular-weight heparin is highly effective in preventing post-operative venous thromboembolism.
