A randomized trial of intensive versus minimal surveillance of patients with resected Dukes B2-C colorectal carcinoma.

BACKGROUND: Colorectal cancer is the third most common and the third most lethal cancer in both men and women in developed countries. About 75% of cases are first diagnosed when the disease is classified as localized or regional, undergo potentially curative treatment and enter a post-treatment surveillance program. Although such programs drain significant resources from health systems, empirical evidence of their efficacy is scanty. PATIENTS AND METHODS: Dukes B2-C colorectal cancer patients who had no evidence of disease at the end of their front-line treatment (surgery and adjuvant radiochemotherapy, if indicated) were eligible for the trial and randomized to two different surveillance programs. These programs differed greatly in the frequency of diagnostic imaging. They had similar schedules of physical examinations and carcinoembryonic antigen (CEA) assessments. Patients received baseline and yearly health-related quality-of-life (HR-QoL) questionnaires. Primary outcomes were overall survival (OS) and QoL. RESULTS: From 1998 to 2006, 1228 assessable patients were randomized, 933 with colon cancer and 295 with rectal cancer. More than 90% of patients had the expected number of diagnostic procedures. Median follow-up duration was 62 months [interquartile range (IQR) 51-86] in the minimal surveillance group and 62 months (IQR 50-85) in the intensive group. At primary analysis, 250 patients had recurred and 218 had died. Intensive surveillance anticipated recurrence, as shown by a significant difference in mean disease-free survival of 5.9 months. Comparison of OS curves of the whole intention-to-treat population showed no statistically significant differences. HR-QoL of life scores did not differ between regimens. CONCLUSION: Our findings support the conclusions of other randomized clinical trials, which show that early diagnosis of cancer recurrence is not associated with OS benefit.

Are strong opioids equally effective and safe in the treatment of chronic cancer pain? A multicenter randomized phase IV 'real life' trial on the variability of response to opioids.

BACKGROUND: Guidelines tend to consider morphine and morphine-like opioids comparable and interchangeable in the treatment of chronic cancer pain, but individual responses can vary. This study compared the analgesic efficacy, changes of therapy and safety profile over time of four strong opioids given for cancer pain. PATIENT AND METHODS: In this four-arm multicenter, randomized, comparative, of superiority, phase IV trial, oncological patients with moderate to severe pain requiring WHO step III opioids were randomly assigned to receive oral morphine or oxycodone or transdermal fentanyl or buprenorphine for 28 days. At each visit, pain intensity, modifications of therapy and adverse drug reactions (ADRs) were recorded. The primary efficacy end point was the proportion of nonresponders, meaning patients with worse or unchanged average pain intensity (API) between the first and last visit, measured on a 0-10 numerical rating scale. (NCT01809106). RESULTS: Forty-four centers participated in the trial and recruited 520 patients. Worst pain intensity and API decreased over 4 weeks with no significant differences between drugs. Nonresponders ranged from 11.5% (morphine) to 14.4% (buprenorphine). Appreciable changes were made in the treatment schedules over time. Each group required increases in the daily dose, from 32.7% (morphine) to 121.2% (transdermal fentanyl). Patients requiring adjuvant analgesics ranged from 68.9% (morphine) to 81.6% (oxycodone), switches varied from 22.1% (morphine) to 12% (oxycodone), discontinuation of treatment from 27% ( morphine) to 14.5% (fentanyl). ADRs were similar except for effects on the nervous system, which significantly prevailed with morphine. CONCLUSION: The main findings were the similarity in pain control, response rates and main adverse reactions among opioids. Changes in therapy schedules were notable over time. A considerable proportion of patients were nonresponders or poor responders. CLINICAL TRIAL REGISTRATION: NCT01809106 (https://clinicaltrials.gov/ct2/show/NCT01809106?term=cerp&rank=2).

Understanding remission in real-world lupus patients across five European countries.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease associated with increased mortality and significant personal, psychological and socioeconomic consequences. An agreed definition of remission is needed and lacking. We sought to visualize 'remission in SLE' in European patients considered by their physicians to be 'in remission' by comparing the reported symptom burden as reported by treating physicians for patients considered to be 'in remission' and those not considered to be 'in remission'. Data for 1227 patients drawn from a multinational, real-world survey of patients with SLE consulting practising rheumatologists and nephrologists in France, Germany, Italy, Spain, and the UK show that physicians classed their patients as 'in remission' despite a considerable ongoing symptom burden and intensive immunosuppressive medication. Patients considered to be 'in remission' still had a mean of 2.68 current symptoms vs 5.48 for those considered to be not 'in remission' (p < 0.0001). The most common symptoms among those seen to be 'in remission' were joint symptoms, fatigue, pain, mucocutaneous involvement, haematological manifestations and kidney abnormalities. The current analysis highlights important ongoing disease activity, symptom burden and immunosuppressive medication in European patients with SLE considered by their treating physician to be 'in remission'. For a further improvement of outcome, there is an urgent need for an international consensus on the definitions for remission among patients with SLE.

Circulating tumor DNA for predicting recurrence in patients with operable breast cancer: a systematic review and meta-analysis.

BACKGROUND: The incorporation of circulating tumor DNA (ctDNA) into the management of operable breast cancer (BC) has been hampered by the heterogeneous results from different studies. We aimed to assess the prognostic value of ctDNA in patients with operable (non metastatic) BC. MATERIALS AND METHODS: A systematic search of databases (PubMed/Medline, Embase, and CENTRAL) and conference proceedings was conducted to identify studies reporting the association of ctDNA detection with disease-free survival (DFS) and overall survival (OS) in patients with stage I-III BC. Log-hazard ratios (HRs) were pooled at each timepoint of ctDNA assessment (baseline, after neoadjuvant therapy, and follow-up). ctDNA assays were classified as primary tumor-informed and non tumor-informed. RESULTS: Of the 3174 records identified, 57 studies including 5779 patients were eligible. In univariate analyses, ctDNA detection was associated with worse DFS at baseline [HR 2.98, 95% confidence interval (CI) 1.92-4.63], after neoadjuvant therapy (HR 7.69, 95% CI 4.83-12.24), and during follow-up (HR 14.04, 95% CI 7.55-26.11). Similarly, ctDNA detection at all timepoints was associated with worse OS (at baseline: HR 2.76, 95% CI 1.60-4.77; after neoadjuvant therapy: HR 2.72, 95% CI 1.44-5.14; and during follow-up: HR 9.19, 95% CI 3.26-25.90). Similar DFS and OS results were observed in multivariate analyses. Pooled HRs were numerically higher when ctDNA was detected at the end of neoadjuvant therapy or during follow-up and for primary tumor-informed assays. ctDNA detection sensitivity and specificity for BC recurrence ranged from 0.31 to 1.0 and 0.7 to 1.0, respectively. The mean lead time from ctDNA detection to overt recurrence was 10.81 months (range 0-58.9 months). CONCLUSIONS: ctDNA detection was associated with worse DFS and OS in patients with operable BC, particularly when detected after treatment and using primary tumor-informed assays. ctDNA detection has a high specificity for anticipating BC relapse.

Measuring quality of life impairment in skeletal muscle channelopathies.

BACKGROUND AND PURPOSE: Fatigue and pain have been previously shown to be important determinants for decreasing quality of life (QoL) in one report in patients with non-dystrophic myotonia. The aims of our study were to assess QoL in skeletal muscle channelopathies (SMC) using INQoL (individualized QoL) and SF-36 questionnaires. METHODS: We administered INQoL and SF-36 to 66 Italian patients with SMC (26: periodic paralysis, 36: myotonia congenita and 4: Andersen-Tawil) and compared the results in 422 patients with myotonic dystrophies (DM1: 382; and DM2: 40). RESULTS: (i) INQoL index in SMC is similar to that in DMs (P = 0.79). (ii) Patients with myotonia congenita have the worst perception of QoL. (iii) Myotonia has the most detrimental effect on patients with myotonia congenita, followed by patients with DM2 and then by patients with DM1 and hyperkalemic periodic paralysis. (iv) Pain is a significant complaint in patients with myotonia congenita, hypokalemic periodic paralysis and DM2 but not in DM1. (v) Fatigue has a similar detrimental effect on all patient groups except for patients with hyperkalemic periodic paralysis in whom muscle weakness and myotonia more than fatigue affect QoL perception. (vi) Muscle symptoms considered in INQoL correlate with physical symptoms assessed by SF-36 (R from -0.34 to -0.76). CONCLUSIONS: QoL perception in patients with SMC is similar to that of patients with DMs, chronic multisystem disabling conditions. Our results provide information to target treatment and health care of these patients. The sensitivity of INQoL to changes in QoL in the SMC needs to be further explored in longitudinal studies.

Cancer-related fatigue and depression: a monocentric, prospective, cross-sectional study in advanced solid tumors.

BACKGROUND: Cancer-related fatigue (CRF) is common in patients with advanced solid tumors and several risk factors are described. The possible role of depression is reported by clinicians despite the association with CRF being unclear. MATERIAL AND METHODS: In this monocentric, cross-sectional, prospective study we recruited patients with advanced solid tumors who were hospitalized at Fondazione IRCCS Istituto Nazionale dei Tumori of Milan. The primary objective was to assess the correlation between CRF and depression. Secondary objectives were the estimation of CRF and depression prevalence and the identification of associated clinical risk factors. CRF and depression were evaluated through the Functional Assessment of Cancer Therapy-Fatigue subscale and the Zung Self Depression Scale (ZSDS) questionnaires. The Cochran-Armitage trend test was used to demonstrate the primary hypothesis. Univariate and multivariate logistic regression models were used to investigate the impact of clinical variables. RESULTS: A total of 136 patients were enrolled. The primary analysis found a linear correlation (P < 0.0001) between CRF and depression. The prevalence of CRF and of moderate to severe depressive symptoms was 43.5% and 29.2%, respectively. In univariate analysis, patients with poor Eastern Cooperative Oncology Group performance status (ECOG PS), anemia, distress, pain, and receiving oncological treatment were at a significantly higher risk for CRF, whereas poor ECOG PS, pain, and distress were risk factors for depression. In multivariate analysis, high levels of ZSDS were confirmed to be correlated to CRF: odds ratio of 3.86 [95% confidence interval (CI) 0.98-15.20) and 11.20 (95% CI 2.35-53.36) for ZSDS of 50-59 and 60-100, respectively (P value for trend 0.002). Moreover, the ECOG PS score was confirmed to be significantly associated with CRF (OR 7.20; 95% CI 1.73-29.96; P = 0.007). CONCLUSIONS: Our data suggest a strong correlation between CRF and depression in patients with advanced solid tumors. Further investigations are needed to better understand this relationship and if depressive disorder therapeutic strategies could also impact on CRF.

Early stage breast cancer follow-up in real-world clinical practice: the added value of cell free circulating tumor DNA.

PURPOSE: Physical examinations and annual mammography (minimal follow-up) are as effective as laboratory/imaging tests (intensive follow-up) in detecting breast cancer (BC) recurrence. This statement is now challenged by the availability of new diagnostic tools for asymptomatic cases. Herein, we analyzed current practices and circulating tumor DNA (ctDNA) in monitoring high-risk BC patients treated with curative intent in a comprehensive cancer center. PATIENTS AND METHODS: Forty-two consecutive triple negative BC patients undergoing neoadjuvant therapy and surgery were prospectively enrolled. Data from plasma samples and surveillance procedures were analyzed to report the diagnostic pattern of relapsed cases, i.e., by symptoms, follow-up procedures and ctDNA. RESULTS: Besides minimal follow-up, 97% and 79% of patients had at least 1 non-recommended imaging and laboratory tests for surveillance purposes. During a median follow-up of 5.1(IQR, 4.1-5.9) years, 13 events occurred (1 contralateral BC, 1 loco-regional recurrence, 10 metastases, and 1 death). Five recurrent cases were diagnosed by intensive follow-up, 5 by symptoms, and 2 incidentally. ctDNA antedated disseminated disease in all evaluable cases excepted two with bone-only and single liver metastases. The mean time from ctDNA detection to suspicious findings at follow-up imaging was 3.81(SD, 2.68), and to definitive recurrence diagnosis 8(SD, 2.98) months. ctDNA was undetectable in the absence of disease and in two suspected cases not subsequently confirmed. CONCLUSIONS: Some relapses are still symptomatic despite the extensive use of intensive follow-up. ctDNA is a specific test, sensitive enough to detect recurrence before other methods, suitable for clarifying equivocal imaging, and exploitable for salvage therapy in asymptomatic BC survivors.

Skip pattern approach toward the early access of innovative anticancer drugs.

BACKGROUND: With the rapid development of innovative anticancer treatments, the optimization of tools able to accelerate the access of new drugs to the market by the regulatory authority is a major issue. The aim of the project was to propose a reliable methodological pathway for the assessment of clinical value of new therapeutic innovative options, to objectively identify drugs which deserve early access (EA) priority for solid and possibly in other cancer scenarios, such as the hematological ones. MATERIALS AND METHODS: After a comprehensive review of the European Public Assessment Report of 21 drugs, to which innovation had previously been attributed by the Italian Medicines Agency (Agenzia Italiana del Farmaco, AIFA), an expert panel formulated an algorithm for the balanced use of three parameters: Unmet Medical Need (UMN) according to AIFA criteria, Added Benefit (AB) according to the European Society for Medical Oncology's Magnitude of Clinical Benefit Scale (ESMO-MCBS) criteria and Quality of Evidence (QE) assessed by the Grades of Recommendation Assessment, Development and Evaluation (GRADE) method. By sequentially combining the above indicators, a final priority status (i.e. EA or not) was obtained using the skip pattern approach (SPA). RESULTS: By applying the SPA to the non-curative setting in solid cancers, the EA status was obtained by 5 out of 14 investigated drugs (36%); by enhancing the role of some categories of the UMN, additional 4 drugs, for a total of 9 (64%), reached the EA status: 2 and 3 drugs were excluded for not achieving an adequate score according to AB and QE criteria, respectively. For hematology cancer, only the UMN criteria were found to be adequate. CONCLUSIONS: The use of this model may represent a reliable tool for assessment available to the various stakeholders involved in the EA process and may help regulatory agencies in a more comprehensive and objective definition of new treatments' value in these contexts. Its generalizability in other national contexts needs further evaluation.

Italian validation of INQoL, a quality of life questionnaire for adults with muscle diseases.

BACKGROUND AND PURPOSE: A quality of life (QoL) questionnaire for neuromuscular diseases was recently constructed and validated in the United Kingdom in a sample of adult patients with a variety of muscle disorders. Preliminary results suggested it could be a more relevant and practical measure of QoL in muscle diseases than generic health measures of QoL. The purpose of our work was: (i) To validate INQoL in Italy on a larger sample of adult patients with muscle diseases (ii) to compare INQoL to SF-36. METHODS: We have translated into Italian and applied language adaptations to the original UK INQoL version. We studied 1092 patients with different muscle disorders and performed (i) test-retest reliability (n = 80); (ii) psychometric (n = 345), known-group (n = 1092), external criterion (n = 70), and concurrent validity with SF-36 (n = 183). RESULTS: We have translated and formally validated the Italian version of INQoL confirming and extending results obtained in the United Kingdom. In addition to good results in terms of reliability, known-group and criterion validity, a comparison with the SF-36 scales showed a stronger association between INQoL total index and SF-36 physical (r = -0.72) than mental (r = -0.38) summary health indexes. When considering comparable domains of INQoL and SF-36 with respect to an objective measure of muscle strength assessment (MMRC), regression analysis showed a stronger correlation using INQoL rather than SF-36 scores. CONCLUSIONS: INQoL is recommended to assess QoL in muscle diseases because of its ability to capture physical limitations that are specifically relevant to the muscle condition.

Axillary nodal involvement by primary tumor features in early breast cancer: an analysis of 2600 patients.

BACKGROUND: Primary tumor characteristics, which are readily available to all clinicians, may aid in selecting the optimal adjuvant therapy for patients with breast cancer (BC). Herein, we investigated the relationship between tumor size, hormone receptor and HER2 status, Ki67 and age with axillary lymph node metastases (ALNM) in early-BC patients. METHODS: We analyzed data on consecutive 2600 early-BC cases collected in the registry of Fondazione IRCC Istituto Nazionale dei Tumori, Milano, Italy. Correlation between Ki67 and primary tumor size (T-size) was calculated by Spearman's rank correlation coefficient. Association of ALNM with Ki67 and other tumor characteristics was investigated by logistic regression. Adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) were estimated in all cases, and separately analyzed according to age, T-size and BC subtype. RESULTS: Large tumor size strongly associated to ALNM, with an adjusted odds ratio (OR) for each 5-mm increase of 1.32 (95% CI 1.24-1.41), except for triple-negative BC (TNBC) cases. In tumors =10 mm, without lymphovascular invasion, representing the strongest predictor of ALNM (OR 6.09, 95% CI 4.93-7.53), Ki67 resulted particularly informative, with a fourfold increased odds of ALNM for values > 30%. CONCLUSIONS: These results raise the question whether axillary node status is redundant in cases with exceptionally good features, i.e., small tumors with low Ki67, or in those candidate to adjuvant systemic treatment/radiotherapy anyway including TNBC, and support the incorporation of primary BC tumor characteristics as stratification factors in ongoing trials aiming at de-escalating axillary surgical procedures.

Pattern and quality of care of cancer pain management. Results from the Cancer Pain Outcome Research Study Group.

Most patients with advanced or metastatic cancer experience pain and despite several guidelines, undertreatment is well documented. A multicenter, open-label, prospective, non-randomised study was launched in Italy in 2006 to evaluate the epidemiology, patterns and quality of pain care of cancer patients. To assess the adequacy of analgesic care, we used a standardised measure, the pain management index (PMI), that compares the most potent analgesic prescribed for a patient with the reported level of the worst pain of that patient together with a selected list of clinical indicators. A total of 110 centres recruited 1801 valid cases. 61% of cases were received a WHO-level III opioid; 25.3% were classified as potentially undertreated, with wide variation (9.8-55.3%) according to the variables describing patients, centres and pattern of care. After adjustment with a multivariable logistic regression model, type of recruiting centre, receiving adjuvant therapy or not and type of patient recruited (new or already on follow-up) had a significant association with undertreatment. Non-compliance with the predefined set of clinical indicators was generally high, ranging from 41 to 76%. Despite intrinsic limitations of the PMI that may be considered as an indicator of the poor quality of cancer pain care, results suggest that the recourse to WHO third-level drugs still seems delayed in a substantial percentage of patients. This delay is probably related to several factors affecting practice in participating centres and suggests that the quality of cancer pain management in Italy deserves specific attention and interventions aimed at improving patients' outcomes.

Illness awareness in terminal cancer patients: an Italian study.

The amount and quality of information and awareness in cancer patients' is a topic frequently debated, but few studies have focussed on terminal patients. This is the objective of the present study that involved two different palliative home-care units in Italy, which recruited 550 terminal cancer patients. Data from patients and their caregivers was prospectively collected with special attention to information patients were provided with when their cancer was diagnosed and patients' awareness of their current health condition. In the case of the information, 67.0% of patients reported they were previously informed about their diagnosis, but only 58.0% seemed to be aware of their terminal condition. The comparison between the caregivers opinions about the level of information provided to the patients and their present awareness and what the patients really know about their own disease shows a high degree of correspondence. Some variables such as age and education level of patients were associated with patient's awareness.

Stopping a trial early in oncology: for patients or for industry?

BACKGROUND: The aim of this study is to assess the use of interim analyses in randomised controlled trials (RCTs) testing new anticancer drugs, focussing on oncological clinical trials stopped early for benefit. MATERIALS AND METHODS: All published clinical trials stopped early for benefit and published in the last 11 years, regarding anticancer drugs and containing an interim analysis, were assessed. RESULTS: Twenty-five RCTs were analysed. The evaluation of efficacy was protocol planned through time-related primary end points, >40% of them overall survival. In 95% of studies, at the interim analysis, efficacy was evaluated using the same end point as planned for the final analysis. As a consequence of early stopping after the interim analysis, approximately 3300 patients/events across all studies were spared. More than 78% of the RCTs published in the last 3 years were used for registration purposes. CONCLUSION: Though criticism of the poor quality of oncological trials seems out of place, unfortunately early termination raises new concerns. The relation between sparing patients and saving time and trial costs indicates that there is a market-driven intent. We believe that only untruncated trials can provide a full level of evidence which can be translated into clinical practice without further confirmative trials.

Prevalence of undertreatment in cancer pain. A review of published literature.

BACKGROUND: Pain is a major health care problem for patients with cancer: despite the existence of guidelines for cancer pain management, undertreatment is a widespread problem. Pain Management Indexes (PMIs) evaluate the congruence between the patient's reported level of pain and the intensity/strength of the analgesic therapy. Negative scores indicate inadequate prescriptions. MATERIALS AND METHODS: We conducted a Medline search using terms for 'pain management', 'index' or 'measure' to select studies which measured undertreatment in cancer settings. Univariate and multivariate logistic regression identified associations between independent predictors and high prevalence of undertreatment. RESULTS: Among the 44 studies identified, 26 studies used the PMI as proposed by Cleeland. The range of negative PMI varied from 8% to 82% with a weighted mean value of 43%. In multivariate analyses, factors associated with negative PMI were date of publication before 2001, provenance from Europe or Asia and countries with a gross national income per capita < $40,000 per year and a care setting not specific for cancer. Age was not a significant predictor for undertreatment. CONCLUSION: Nearly one of two patients with cancer pain is undertreated. The percentage is high, but consists of a large variability of undertreatment across studies and settings.

Metabolic syndrome, psychological status and quality of life in obesity: the QUOVADIS Study.

OBJECTIVE: We aimed to investigate the association of the clinical variables of the metabolic syndrome (MS) and psychological parameters on health-related quality of life (HRQL) in obesity. In particular, our aim was to investigate the relative impact of physical symptoms, somatic diseases and psychological distress on both the physical and the mental domains of HRQL. DESIGN: Cross-sectional study. SUBJECTS: A cohort of 1822 obese outpatients seeking treatment in medical centers. MEASUREMENTS: HRQL was measured by the standardized summary scores for physical (PCS) and mental (MCS) components of the Short Form 36 Health Survey (SF-36). Patients were grouped according to tertiles of PCS and MCS. Metabolic and psychological profiles of PCS and MCS tertiles were compared by discriminant analysis. RESULTS: The profile of metabolic and psychological variables was tertile-specific in 62.4 and 68.3% of patients in the lowest and highest tertiles of PCS, respectively, while concordance was low in the mid-tertile (32.8%). Concordance was very high in the lowest (74.4%) and in the highest (75.5%) tertiles of MCS, and was fair in the mid-tertile (53.2%). The main correlates of PCS were obesity-specific and general psychological well-being, BMI, body uneasiness, binge eating, gender and psychiatric distress. Only hypertension and hyperglycemia qualified as correlates among the components of MS. The components of MS did not define MCS. CONCLUSIONS: Psychological well-being is the most important correlate of HRQL in obesity, both in the physical and in the mental domains, whereas the features of MS correlate only to some extent with the physical domain of HRQL.

Do cancer patients change their diet in the e-health information era? A review of the literature and a survey as a proposal for the Italian population.

In recent years, there has been an explosion in the amount of available information on cancer in parallel with an ever-increasing number of cancer survivors. Cancer patients and long-term survivors are known to be more sensitive to health-related information and dietary changes could represent a potential consequence of this huge availability of messages. In our review about dietary changes after cancer diagnosis, we found that this topic is particularly investigated among the breast cancer population. The literature examined show that breast cancer patients modify their eating habits after diagnosis in a percentage that varies between approximately 30% and 60%. The most reported changes were an increased consumption of fruit and vegetables, a decrease in the consumption of red meat, fats and sugary foods. Patients who reported changes were more likely to be younger, with higher educational levels and with a longer period of time since their diagnosis of cancer. It also emerged that cancer patients are often more likely to use supplements. This topic has not been investigated in cancer patients in Italy, therefore, we propose an approach to explore it with a structured questionnaire: The "ECHO SURVEY - Eating habits CHanges in Oncologic patients".

Overweight and obesity in Italian adults 2004, and an overview of trends since 1983.

OBJECTIVE: Overweight has been increasing in several developed countries over the last few decades. No update information on the issue is available for Italy. DESIGN AND SETTING: We conducted a computer assisted personal in-house interview survey in March-April 2004, on a sample of 2932 Italian individuals (1407 men and 1525 women) aged 18 years or over, representative of the general adult Italian population. Information on weight and height was self-reported. RESULTS: Overall, 3.4% of the Italian adult population were underweight (< 18.5 kg/m2, 0.9% of men and 5.8% of women), 31.3% were overweight (25.0-29.9 kg/m2, 38.4% of men, 24.7% of women), and 8.2% were obese (> or = 30.0 kg/m2, 7.4% of men and 8.9% of women). Overweight or obesity was reported by 14.2% of subjects aged 18-24 years (20.6% of men and 7.6% of women). The highest proportions of overweight and obese subjects were in the 45-64 year age group for men (51.4% overweight, 10.0% obese) and in the > or = 65 year age group for women (38.8% overweight, 13.8% obese). Age- and sex-standardised prevalence of overweight or obesity was 36.0% for more educated subjects, and 54.0% for less educated ones. It was 32.3% in northern, 44.3% in central and 47.0% in southern Italy. Overweight increased from 1983 to the early 1990s, and levelled off thereafter. Prevalence of obesity remained around 8-9% across the last 20 years. CONCLUSIONS: Trends of overweight and obesity in Italy are more favourable than in several developed countries. Still, approximately 15 million of Italian adults are overweight and 4 million obese.

[Health related quality of life (HRQoL) assessment in uremic patients: a qualitative review of concepts, methods, available instruments and results]. / Misurare la Qualità della Vita correlata alla Salute (QdV-S) nel paziente uremico: una review dei concetti, dei metodi, degli strumenti disponibili e dei risultati.

The health related quality of life (HRQoL) assessment is a complex and multidimensional concept usually defined as the perception by individuals of the impact of diseases and medical treatments on physical, psychological and social aspects of health and life. HRQoL has become more popular in the last 20 yrs as an important indicator of the effectiveness of the medical care in clinical research protocols, and as part of so-called patient-reported outcomes (PRO), which are concepts concerning aspects of health perceived, reported and rated by study subjects or patients. Generic and disease specific questionnaires are usually used to assess the individual's perceptions about health and life, and more valid and reliable instruments are now available to use in research settings. Instruments that can be useful in daily clinical practice, in the management of the single patient, are not yet available. A large portion of the scientific literature dealing with HRQoL is actually focused on many aspects of uremic syndrome, renal transplantation and dialysis therapies, probably because several reasons make this clinical setting particularly favorable for HRQoL assessment. Early referral to a nephrologist, anemia treatment with epoetin, daily and nocturnal dialysis, kidney transplantation, a program of physical exercise and the treatment of some co-existent conditions and symptoms (i.e. depression, pain, erectile dysfunction and restless leg symptoms) are the most effective ways to ameliorate HRQoL in renal patients. Moreover, HRQoL is a reliable prognostic factor for morbidity and mortality in uremic patients.

The Italian SF-36 Health Survey: translation, validation and norming.

This article reports on the development and validation of the Italian SF-36 Health Survey using data from seven studies in which an Italian version of the SF-36 was administered to more than 7000 subjects between 1991 and 1995. Empirical findings from a wide array of studies and diseases indicate that the performance of the questionnaire improved as the Italian translation was revised and that it met the standards suggested by the literature in terms of feasibility, psychometric tests, and interpretability. This generally satisfactory picture strengthens the idea that the Italian SF-36 is as valid and reliable as the original instrument and applicable and valid across age, gender, and disease. Empirical evidence from a cross-sectional survey carried out to norm the final version in a representative sample of 2031 individuals confirms the questionnaire's characteristics in terms of hypothesized constructs and psychometric behavior and gives a better picture of its external validity (i.e., robustness and generalizability) when administered in settings that are very close to real world.
