Confirmatory validation analysis of the PROFFIT questionnaire to assess financial toxicity in cancer patients.

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.

Report from the Melanoma Independent Board First Melanoma MIB Conference, 21-22 October 2013.

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.

Report from the OECI Oncology Days 2014.

The 2014 OECI Oncology Days was held at the 'Prof. Dr. Ion Chiricuta' Oncology Institute in Cluj, Romania, from 12 to 13 June. The focus of this year's gathering was on developments in personalised medicine and other treatment advances which have made the cost of cancer care too high for many regions throughout Europe.

A dedicated website for cancer subjects, the nutritional support study: preliminary results.

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.

Immunogenicity of allo-vesicle carrying ERBB2 tumor antigen for dendritic cell-based anti-tumor immunotherapy.

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.

Impact of different low-dose ritonavir regimens on lipids, CD36, and adipophilin expression.

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).

Metabolic-inflammatory changes, and accelerated atherosclerosis in HIV patients: rationale for preventative measures.

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.

Low molecular weight heparins in cardiovascular medicine.

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.

Chronic heart failure- potential for pharmacological intervention.

Heart failure is commonly associated with vascular diseases and a high rate of athero-thrombotic events, but the risks and benefits of antithrombotic therapy are unknown. The incidence of thromboembolism in heart failure patients (which may include stroke, peripheral embolism, pulmonary embolism) seems to be around 2%, based on the data available from several small studies. However, the incidence of thromboembolism should greatly depend upon what is being looked at in each of these studies, as it will (generally) not be individually categorised. There is very little true epidemiological data to base this figure. The pathophysiology of heart failure is complex. There are many well- recognised factors, which are associated with thrombosis in heart failure patients, such as vascular abnormalities, increased coagulability and impaired blood flow. In the past 50 years, many studies have been performed to find out if oral anticoagulation is of benefit for the prevention of thromboembolism in patients with heart failure. Expert therapeutic guidelines in the Europe and North America agree that there is insufficient evidence to recommend that antithrombotic therapy should be given to patients with heart failure, unless they have atrial fibrillation or, perhaps, a previous thrombo-embolic episode. There is a lack of evidence for any antithrombotic agent that is effective in patients with heart failure; therefore, randomised clinical trials need to be designed to test the hypothesis that patients with chronic heart failure would have benefit from anticoagulant therapy. This review summarises the incidence, potential mechanism and therapeutic approaches for the management of thromboembolism in heart failure.

Therapeutic apheresis in low weight patients: technical feasibility, tolerance, compliance, and risks.

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%).

Improving information to Italian cancer patients: results of a randomized study.

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.

Immunoadsorption apheresis (Selesorb) in the treatment of chronic hepatitis C virus-related type 2 mixed cryoglobulinemia.

In this short-term open label clinical pilot study, conducted at one center, the immune complex dextran sulphate adsorber (Selesorb) was used to treat four female patients aged 59-69 with HCV-related cryoglobulinaemia, vasculitis and/or neuropathy. The primary trial objective was to assess the clinical efficacy of the immunoadsorber. The secondary objective of the trial was to determine the safety of the adsorber and to investigate the adsorption capacity, measured as the adsorption of cryoglobulin-related immune complexes and the resulting influence on plasma components of the immune system. The patients have been submitted to treatment with the immunoadsorber, at approximately 1-3 days intervals, completing six sessions. The follow-up was one month. In the patients treated with Selesorb, we observed a statistically significant decrease in plasma of all classes of immunoglobulins (IgA: 5-28%; IgG: 14-44%; IgM: 8-38%). In two patients with peripheral neuropathy secondary to cryoglobulinemia, the symptomatology was improved. In a third patient the neurological involvement was substantially unchanged, and the same unsuccessful outcome was observed for Sjögren syndrome is concerned. Nevertheless, the two patients with lower extremity vasculitis showed an appreciable improvement. We failed to observe significant side effects directly related to the use of this immunoadsorbent.

Unexpected products via singlet oxygen oxygenation of functionalized 5,6-dihydro-1,4-oxathiins

[formula: see text] Single oxygen oxygenation of 5,6-dihydro-1,4-oxathiins substituted at C-3 with an electron-withdrawing group leads stereoselectively to ketosulfoxides 5 and 6, instead of the expected dicarbonyl compounds 3. A mechanism involving an unprecedented intramolecular rearrangement of the corresponding dioxetanes 2 is proposed.

Low molecular weight heparin for treatment of acute myocardial infarction (FAMI): Fragmin (dalteparin sodium) in acute myocardial infarction.

The benefit of using subcutaneous low molecular weight heparin for the treatment of acute myocardial infarction is not known. The aim of this study was to determine the efficacy of a low molecular weight heparin (dalteparin sodium) for the treatment of acute myocardial infarction in patients not treated with thrombolytic therapy. Twenty-nine cardiological centres from leading hospitals in India participated in this prospective, multicentre, double-blind, placebo-controlled study in two phases which included 1128 patients with acute myocardial infarction. In the acute phase (between day 1 and 3 of admission) all the patients received a weight-adjusted dose of subcutaneous dalteparin (120 IU/kg twice daily). In the second, double-blind phase of acute myocardial infarction, patients were randomised to receive a fixed dose of dalteparin (7,500 IU) or an identical placebo injection for 30 days. A composite primary endpoint of death, reinfarction, recurrence of angina and emergency revascularisation was used. All the 1128 patients with acute myocardial infarction were included in the trial. In the acute phase, the composite primary endpoint was observed in 58 (5.1%) patients. Of 1037 paients who were randomly assigned to receive a fixed dose of dalteparin (n=519) or placebo (n=518), the composite primary event rate was 6.7 percent and 7.0 percent, respectively (RR 0.97; 95% CI 0.62-1.52; p=0.90). To conclude, treatment with dalteparin administered subcutaneously in a weight-adjusted dose of 120 IU/kg twice daily resulted in a lower than expected mortality during the acute phase of myocardial infarction. A lower fixed once daily dose of 7,500 IU during the chronic phase did not confer additional protection.
