RESUMO

BACKGROUND AND AIMS: Excess salt intake is the leading dietary risk factor for cardiovascular disease in most countries, including Italy. While the cost-effectiveness of interventions aimed to reduce salt intake has been proved, the WHO recommendation to reduce salt intake by 30 % at the global level by 2025 is far from being reached. METHODS AND RESULTS: In Italy, two surveys of the general adult population have established that the average salt intake is still almost twice the WHO recommendation although it was reduced by 1.2 g/day between 2008-12 and 2018-19. Previous investigations had shown that non-discretionary salt added by the industry or by local craft producers represents at least 50 % of the total intake and indicated cereal-based products as the main source of non-discretionary salt. Two recent studies conducted by the Italian Society of Human Nutrition "Young Working Group" have provided updated information on the salt content of almost three thousand cereal-based products currently available on the Italian food market and shown that most of the items evaluated had a sodium content much higher than the sodium benchmarks recently proposed by WHO. CONCLUSIONS: Italy has built the foundations of an effective population strategy for salt intake reduction: it is time however to proceed with full commitment to food reformulation if any substantial further progress has to be made. Salt benchmarks for Italy need to be defined for the food categories most relevant to population salt intake and their implementation should ideally be mandatory after consultation with food producers.

RESUMO

BACKGROUND/AIMS: To investigate the effectiveness and safety of sorafenib after radiofrequency ablation (RFA) in patients with hepatocellular carcinoma (HCC). METHODOLOGY: 44 intermediate or advanced HCC patients received sorafenib treatment after debulking with RFA therapy. Time to progression (TTP), response rate (RR), duration of sorafenib treatment and adverse effects were evaluated. An explorative comparison was performed with patients treated with sorafenib only. RESULTS: At 12 months, TTP was 10.3 months (range: 1-32). RR was 61% with 2 complete responses, and duration of sorafenib therapy was 10.9 months (1-32). No new safety concerns were report-ed. With sorafenib only, TTP was 7.2 months (range: 0-38) and RR was 40%, with one complete response; duration of therapy was 7.3 months (0-38). CONCLUSIONS: The sequence of RFA and sorafenib appears effective and safe in HCC patients. These findings could support the use of a sequential treatment with RFA and sorafenib in HCC patients.

RESUMO

Food Neophobia (FN), defined as the reluctance to eat new or unfamiliar foods, mainly concerns fruit, vegetables, and legumes, typical of the Mediterranean Diet (MD). Considering these premises, this study aimed to clarify the relationship between FN and AMD in a sample of Italian children and their association with some socio-demographic factors and children's nutritional status. A sample of 288 children aged 3-11 years participated in an assessment carried out with a questionnaire evaluating FN and AMD, respectively, with the Child Food Neophobia Scale (CFNS) and the KIDMED test. Most of the sample showed an intermediate (67.3%) or high level of FN (18.1%), with high rates among 6-11-year-old children (63.9%) and especially in those who were the only child (50%). The AMD was mostly low (29.5%) or medium (54.8%) and reached lower levels among higher neophobic children (51.9%; p value < 0.05). The present results confirm the study hypothesis that FN is a driver of MD abandonment and shows the positive effects on children's eating habits and siblings. Finally, this study proves the relevance of adopting effective feeding strategies against FN to avoid its maintenance in adulthood and the detrimental effects on future overall health and well-being.

RESUMO

Growing worldwide food demand with its environmental impacts requires a reshaping of food consumption. This study aims to evaluate the degree of Italian consumers' awareness of sustainability and whether protein alternatives to meat could be accepted. A cross-sectional survey was carried out on a group of 815 respondents, representative of the Italian adult population for geography, gender, and age, using multivariate analysis together with cluster analysis. Lack of awareness of the consequences of food choices on the environment was found in 45% of respondents, and 51% reduced their consumption of meat. Typical foods of the Mediterranean diet (84% legumes 82% eggs, and 77% fish) were selected as the preferred sources of protein to replace meat, while insects and insect-based products were less accepted (67%). The importance of meat is the latent factor that explains more than 50% of the common variance observed in the factor analysis. The cluster analysis confirmed the importance of meat for Italian consumers, emphasizing other aspects of the sustainability of food choices. Cluster 1 (25.6%) considered meat very important. Two out of five clusters (clusters 2 and 3, 38%) considered meat replaceable in the diet, and cluster 4 (31.3%) included meat consumers that were willing to be sustainable. Cluster 5 identifies the "unsustainable consumers" (5.7%). In conclusion, besides the perceived importance of meat, there is room for recommendations for its reduction by proposing alternative foods already present in the Mediterranean diet.

RESUMO

Objective: This paper aims to evaluate whether changes in lifestyle and eating habits resulting from the Covid-19 emergency have influenced the post-pandemic level of food neophobia and in children living in an Italian central region. Methods: A sample of 99 children took part in a retrospective assessment carried out with a self-administrated questionnaire. Pre and post-pandemic evaluation of eating habits, physical activity, and lifestyle indicators was carried out. Food neophobia was evaluated following the Child Food Neophobia Scale (CFNS). Descriptive statistics were produced. A contingency analysis was performed to check associations between variables. Results: For a large part of the sample (97%) the selective food refusal did not change during the pandemic period. About 70% of participants did not change their eating habits, with some subgroups reporting an increase in the consumption of fruits (22.2%), vegetables (19.2%), and legumes (21.2%). Relevantly the impact of the pandemic on the sedentary attitude passed from 25.3 to 70.7%. Neophobia was not associated with ponderal status (p-value 0.5). However, in normal-weight children, a high prevalence of intermediate-level neophobia (78.4%) was found. 39.4% of the studied children were involved in meal preparation during social isolation, with an increase in the proportion of children that shared all meals with their family (32.3% vs. 78.8%). Non-coercive parent behaviors in reaction to food refusal were associated with low levels of neophobia (p-value < 0.05). Discussion: In this sample, for the effect of parents' attitudes, the pandemic positively affected children's food habits and, consequently, the level of neophobia after the social restrictions. The main implication of the study is the importance of capitalizing on the period of restrictions in order to involve children in meal sharing and food preparation.

RESUMO

This study aimed to describe the process of validation of a questionnaire assessing Italian consumers' perception of food sustainability. The study has a multiphase design. Phase 1 consisted in translating and structuring the questionnaire. Phase 2 aimed at assessing the validity of the content by experts. Phase 3 consisted of a pilot study (n = 150) carried out to revise the questionnaire based on the reactions of consumers representing the target group of the assessment. The questionnaire showed adequate content validity for 11 out of 14 questions (>0.79) and S-CVI/Ave > 0.80. Cronbach's alpha values ranged from 0.08 to 0.90. The construct with insufficient results (0.08) was changed because it failed to correlate with the rest of the questionnaire. The factor analysis permitted the identification of questions that needed improvement in terms of comprehensibility, elimination of redundancies, and repetitions. The validated questionnaire included 12 questions (71 response options); 3 sections were identified: food sustainability knowledge (4 questions-30 items); sources of proteins alternative to meat (3 questions-20 items); eating behaviors (5 questions-21 items). This study showed the importance of validation before the administration on a large scale of a questionnaire on a topic such as sustainability still lacking large support from consensus documents.

RESUMO

The fourth edition of the Italian Dietary Guidelines (IDGs) for Healthy Eating was published in 2019. The objective of this paper is to describe the developmental process of IDGs, the main recommendations, the differences with previous revisions, and the concordance and differences with international guidance on a healthy diet. A National Commission oversaw IDG development. A Scientific Dossier (SD), including analysis on nutrition, health, and risk factors status in Italy, was the reference for IDGs preparation. The IDGs are based on the principles of the Mediterranean Diet and are mainly aimed to prevent obesity and nutrition-related non-communicable diseases. The IDGs included 13 directives that were divided into four conceptual blocks: i) how to balance weight; ii) foods to be promoted; iii) foods to be limited; and iv) how to ensure a varied and sustainable diet. Each directive has a box summarizing the key recommendation, myths lists, and false beliefs to be dispelled. The topics of sustainability and the correct approach to food supplementation and weight-loss diet were introduced in the present edition of IDGs. This paper contributes to the debate on the complexity of derivation of Dietary Guidelines and their adaptation to the national context.

RESUMO

Novel human coronavirus disease (COVID-19), an infectious respiratory disease, has affected more than 50 million people around the world up to November 2020, thereby becoming the fifth documented pandemic since the Spanish flu in 1918. SARS-CoV-2 virus originated in China and evolved for 4 months within the country before becoming a global threat. There is currently no drug approved by the Food and Drug Administration (FDA) for which efficacy on the virus has been proved. Therefore, the only strategy against this virus is to apply measures that are capable of reducing its spread, such as isolation and quarantine, social distancing, community-wide containment, and strict enforcement of hygiene. Quarantine has proved to be effective in combating the spread of the virus; however, it has inevitably led to a radical change in the lives of people. Studies have been conducted in Italy and some European countries to highlight the role that quarantine has played in determining the lifestyle changes both in eating habits and physical activity and their possible correlation with increase in weight. The selection criteria involved answering a questionnaire that included information on the weight status and at least one of the other two aspects: changes in eating habits and/or physical activity during the quarantine period. The results obtained indicate, in general, that the negative effect of quarantine was on eating habits and physical activity. This was based on the observation that there has been an increase in food consumption and a reduction in physical activity with a consequent increase in weight.

RESUMO

To limit the spread of coronavirus SARS-CoV-2, a nationwide lockdown started in Italy in March 2020. In this unpredictable situation, a cross-sectional study using an online questionnaire was carried out by the Observatory on Food Surplus, Recovery and Waste of CREA Food and Nutrition Centre. The aim of this work was to evaluate how Italian habits changed during this period, the determinants of changes, and the effect on food waste prevention. In a sample of 2678 respondents, 62% showed low Adherence to the Mediterranean Diet (AMD). During lockdown many of participants improved the quality of their diet, increasing their consumption of fruit (24.4%), vegetables (28.5%), legumes (22.1%), nuts (12%), and fish or shellfish (14%). Unfavorable changes were observed with the excessive consumption of sweets or pastries (36.9%) and comfort foods (22.7%), and a lack of physical activity (37.2%). The main novelty of this study was the examination of dietary changes identified by a cluster analysis. Respondents with generally high AMD improved their eating habits, while the habits of the respondents with generally low AMD remained unchanged. In addition, nearly 80% of respondents were sensitive to food waste. The study provides a useful contribution to the debate on nutritional recommendations in case of further lockdown.

RESUMO

OBJECTIVE: The purpose of this study was to examine the results of percutaneous radiofrequency ablation of both medium-sized hepatocellular carcinoma (HCC) and the accompanying main portal venous tumor thrombus in patients with cirrhosis. SUBJECTS AND METHODS: From January 2005 to January 2008, among 1,837 consecutively registered patients with HCC seen at our institution, 412 had HCC and portal venous invasion; 27 of the 412 had a single HCC nodule accompanied by main portal venous tumor thrombus. Thirteen patients (10 men, three women; mean age, 70 years; range, 66-74 years) with 13 HCC nodules 3.7-5 cm in diameter extending into the main portal trunk underwent percutaneous radiofrequency ablation. Fourteen matched patients (10 men, four women; mean age, 69 years; range, 67-73 years) with 14 HCC nodules 3.6-4.8 cm in diameter extending into the main portal trunk refused radiofrequency ablation and composed the control group. Diagnosis of main portal venous tumor thrombus was made with fine-needle biopsy in all cases. Radiofrequency ablation was performed first on the main portal venous tumor thrombus and then on the HCC nodule. Efficacy of radiofrequency was defined as complete necrosis of HCC and complete recanalization of the main portal trunk and its branches. HCC necrosis was evaluated with enhanced CT. Recanalization of portal vessels was analyzed with color Doppler and contrast-enhanced ultrasound. Radiofrequency ablation was performed under ultrasound guidance with a perfused needle electrode. RESULTS: Complete necrosis of the HCC associated with complete recanalization of the main portal vein and its branches was achieved in 10 patients (efficacy, 77%). In the other three patients, necrosis of the HCC ranged from 70% to 90%, and recanalization of the main portal trunk was not complete. No major complications occurred. In three cases, mild to moderate ascites and increased aspartate aminotransferase and alanine aminotransferase levels were found. The follow-up periods ranged from 3 to 36 months among the treated patients and 2 to 10 months among the untreated patients. The cumulative survival rate was 77% 6, 12, and 36 months after procedure in the treated group and 43% and 0% 6 and 12 months after diagnosis in the untreated group (p < 0.0001). All 10 successfully treated patients were alive and the portal system was patent at the end of the follow-up period. All three untreated patients died of progressive disease within 5 months of diagnosis. CONCLUSION: Radiofrequency ablation can destroy both single intraparenchymal medium-sized HCCs and the accompanying main portal venous tumor thrombus with high efficacy and safety and a low rate of complications.

RESUMO

Accurate lymph node characterization is important in a large number of clinical settings. We evaluated the usefulness of Contrast Enhanced Ultrasound (CEUS) in distinguishing between benign and malignant lymph nodes compared with conventional ultrasonography in the differential diagnosis of superficial lymphadenopathy.We present our experience for 111 patients enrolled in a single center.111 superficial lymph nodes were selected and only 1 lymph node per patient underwent CEUS. A definitive diagnosis for all lymph nodes was obtained by ultrasonographically guided biopsy and/or excision biopsy.The size of the lymph nodes, the site (neck, axilla, inguinal region) being easily accessible for biopsy, and the US and color Doppler US characteristics guided us in selecting the nodes to be evaluated by CEUS.In our study we identified different enhancement patterns in benign and malignant lymph nodes, with a high degree of diagnostic accuracy for superficial lymphadenopathy in comparison with conventional US.

RESUMO

BACKGROUND/AIM: The impact of radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI) on survival in patients with small hepatocellular carcinoma (HCC) is unclear. We compared their efficacy in cirrhotics with single HCC ≤2 cm. PATIENTS AND METHODS: Two hundred forty-four cirrhotics with single HCC ≤2 cm treated with PEI (108 cases) or RFA (136 cases) were enrolled in the study. Eighty-one patients in each group were selected for propensity score matching analysis. RESULTS: The five-year survival was not significantly different (64.7% in PEI and 72.9% in RFA group) but the 5-year recurrence (73.3% in PEI and 49% in RFA group, p=0.023) and local tumor progression (49% in PEI and 30.1% in RFA group, p=0.018) were higher in the PEI group. CONCLUSION: PEI and RFA are equally effective in treating HCCs smaller than 2 cm in terms of 5-year survival, despite higher cumulative and local recurrence rates, in patients treated with PEI.

RESUMO

UNLABELLED: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death. Portal vein tumor thrombus (PVTT) is one of the most dreadful complications of HCC and is associated with a median survival time of 2.7-4.0 months. The optimal treatment for HCC with PVTT has not yet been established. The aim of the present study was to report long-term results of percutaneous radiofrequency (RF) ablation of both HCC single nodule (up to 5 cm in diameter) and neoplastic main portal vein thrombus, compared to no-treatment. PATIENTS AND METHODS: From January 2005 to January 2010, out of 2,847 consecutive cirrhosis patients, 672 had HCC and main portal vein tumor thrombus (MPVTT); among these, 57 had a single HCC with MPVTT. Thirty-five patients with 35 single HCC nodules (ranging from 3.7 to 5 cm in diameter) underwent percutaneous RF ablation of both the nodule and the thrombus (cases); 22 patients refused RF ablation or any other treatment (controls). RESULTS: A complete necrosis of HCC nodules associated with re-canalization of main portal trunk (MPT) and its branches were observed in 26 patients (success rate=74%). The 1-, 3- and 5-year cumulative survival rates of patients were 63%, 30% and 20%, respectively. The 12-month cumulative survival rate of controls was 0% (p<0.0001). The difference was statistically significant (p<0.001; harzard ratio (HR)=2.88; 95% confidence interval (CI)=1.57-5.39). The 3- and 5-year cumulative disease-free survival rates of the patients were 35% and 22%, respectively. No deaths occurred. CONCLUSION: RF ablation of HCC and the accompanying MPVTT significantly prolongs long-term survival compared to no-treatment. The procedure is safe and should be considered as a new and effective tool in the treatment of advanced HCC.

RESUMO

An increasing number of people regularly eats lunch away from home, using catering services. In this context, therefore, it is extremely important to improve the meals' quality, remaining faithful to the principles of hygiene, nutritional and organoleptic quality and proper food handling. At the same time, it is necessary to promote food choices, nutritionally correct, by evaluations of appropriateness of menus. The study of food waste allows an evaluation of the nutritional habits of consumers and an important economic consideration of the costs incurred for the implementation of the service. This becomes even more important in some particularly sensitive groups, such as children and elderly. The purpose of this work is to test a model of semi-quantitative evaluation of waste to monitor food consumption in two different catering contexts (educational and business), in order to improve the service for school students and other consumers.

RESUMO

BACKGROUND: Radiofrequency Ablation is the most widely performed percutaneous treatment for Hepatocellular Carcinoma. This multicentre study was aimed at assessing the complication, overall survival and disease-free survival rates in cirrhotic patients with single Hepatocellular Carcinoma nodule ≤3 cm undergoing Radiofrequency Ablation. METHODS: Data of 365 patients (59% males; mean age 67 ± 8 years), Child-Pugh A/B, with single Hepatocellular Carcinoma nodule ≤3 cm (tumours >2-3 cm = 127/236), showing complete necrosis after Radiofrequency Ablation between 1998 and 2010 in 7 Italian Centers were retrospectively reviewed. Complication, overall survival and disease-free survival rates were analyzed as main clinical end-points. RESULTS: Major complications were observed in 8 patients (2.2%) and minor complications in 23 patients (6.3%). The 3-, and 5-year overall survival rates were 80% and 64%. One hundred and seven patients (29.5%) died, being 41 deaths (38.3%) Hepatocellular Carcinoma-related. At multivariate analysis only age (p = 0.04; OR 2.29), ascites (p < 0.001; OR 3.74) and Child-Pugh class ≥B8 (p = 0.003; OR 2.42) were confirmed as independent predictors for overall survival. The disease-free survival rates at 3- and 5-year were 50%, and 41.8%. CONCLUSIONS: Radiofrequency Ablation is an effective and safe tool for the treatment of single Hepatocellular Carcinoma ≤3 cm providing excellent 5-year overall survival and disease-free survival rates. Patient's age and liver status appeared as main determinants of outcome.

RESUMO

Liver hydatidosis is the most common clinical presentation of cystic echinococcosis. Although liver cystic hydatidosis is considered a benign disease and many patients do not develop symptoms for years, its complications can be severe and life threatening (usually as a consequence of rupture in the biliary tree, in the peritoneum, in the bronchi, and of anaphylactic shock), thus, treatment is recommended for all viable and active hydatid liver cysts. Among the therapeutical options available for this disease, such as open and laparoscopic surgery and chemotherapy, percutaneous treatments have gained considerable interest over the last two decades, due to their efficacy, safety and high patient acceptability. Percutaneous treatments for liver cystic hydatidosis were once discouraged due to the risk of anaphylaxis following cyst puncture. Following the first uneventful attempts in the mid '80's, these treatments were increasingly used and techniques such as PAIR (Puncture, Aspiration, Injection, Re-aspiration) and its variants were developed and implemented in clinical practice. Although the evidence currently available is not sufficient to support or refuse the superiority of PAIR in terms of efficacy, numerous studies have demonstrated that it carries lower rates of morbidity, mortality, and disease recurrence and is associated with shorter hospital stays compared with surgery. The present review provides a brief history of percutaneous treatments for liver cystic hydatidosis, summarizes the currently available evidence on the subject, gives a brief overview of potential future developments in this field focusing on radiofrequency ablation techniques and presents some new patents on the issue.

RESUMO

BACKGROUND: During the progression from low-grade dysplastic nodule (DN) to progressed hepatocellular carcinoma (HCC), intranodular portal tracts gradually disappear, while unpaired arteries develop increasingly. Contrast-enhanced ultrasound (CEUS) is highly accurate in depicting intranodular vascularity. This study evaluates the usefulness of CEUS in the characterization of DN, early HCC and progressed HCC in cirrhotic livers. MATERIALS AND METHODS: Forty consecutive patients with cirrhosis and a single hepatic nodule ≤2 cm underwent CEUS and subsequent ultrasound-guided biopsy of the nodule. Imaging and pathological findings of DN and HCC were compared. RESULTS: The homogeneous pattern of hypervascularization during the arterial phase identified progressed HCC with a sensitivity of 90.9% and a specificity of 100%, whereas the inhomogeneous and reticular pattern identified early HCC with a sensitivity of 85.7% and a specificity of 96.1%. CONCLUSION: DN, early HCC and progressed HCC can be accurately differentiated with CEUS on the basis of the vascularization pattern during the arterial phase.

RESUMO

PURPOSE: To evaluate the usefulness and safety of radiofrequency ablation for primary and recurrent intrahepatic cholangiocarcinoma (ICC) in our single centre experience. MATERIALS AND METHODS: Ten patients with ICC refusing or not eligible for surgery underwent radiofrequency ablation for their tumor. The ICC was primary in 9 cases and recurrent, after 2 previous resections, in 1 patient. Radiofrequency ablation was performed percutaneously under ultrasound guidance using a 15G perfused electrode. Technical success of the procedure was assessed by contrast-enhanced ultrasound (CEUS). Technical effectiveness was evaluated by CEUS and contrast enhanced CT 1 month after the last course of a defined ablation protocol. Follow-up contrast enhanced CT or MRI were performed every 3-6 months. RESULTS: RFA was always technically successful and effective for ICC lesions ≤3.4 cm and ineffective for lesion ≥4 cm. After a median follow-up of 19.5 months (range 9-64 months), 8 patients were still alive while 2 had died due to tumor progression. The 1-, 3- and 5-year overall survival rate of all patients with ICC of our series were 100%, 83.3% and 83.3%. No major complication was observed. CONCLUSION: Radiofrequency ablation seems to be a safe and effective option for small (≤3.4 cm) ICC nodules. In addition it may be considered as a palliative treatment for larger tumors.
