RESUMEN

Abstract: Our letter discusses the concept of 'Nutritional Prevention Hesitancy', comparing it to the well-studied phenomenon of 'Vaccine Hesitancy'. Both hesitancies can be fueled by 'infodemics', the rapid spread of accurate and inaccurate information that can lead to public confusion and mistrust in authoritative sources. Drawing parallels between the two, the text highlights that nutritional prevention hesitancy can result in individuals not adopting evidence-based nutritional strategies, potentially leading to poorer health outcomes. The text emphasizes the critical role of diet in preventing diseases such as heart disease, diabetes, and certain types of cancer, and underscores the need for multifaceted strategies to combat misinformation and promote healthier dietary habits.

RESUMEN

Abstract: Italy's National Prevention Plan 2020-25 is the first to address nutritional prevention, highlighting its importance in combating chronic diseases. This letter discusses the relationship between food safety, nutritional security, and the need for nutritional prevention in the plan. Chronic diseases, such as cardiovascular disease, cancer, and diabetes, are significant public health concerns in Italy, with poor nutrition being a critical risk factor. Incorporating nutritional prevention can promote healthy eating habits, food security and sustainability, reduce healthcare costs, and promote social cohesion and equality. Successful implementation will require cooperation among the government, the private sector, and the civil society to ensure healthier food choices and prevent chronic diseases in Italy.

RESUMEN

BACKGROUND: The intervention "Med-Anticancer Food Program" has proven to be effective in promoting the Mediterranean Diet, significantly increasing the Mediterranean Adequacy Index in healthy subjects. There are no studies that have investigated the effectiveness of this intervention in individuals who have had a diagnosis of cancer. OBJECTIVE: To perform a pilot study to assess the opportunity of employing the methodology of the Med-Anticancer Food Program in order to encourage "long-term cancer survivors" to adhere to the Mediterranean Diet, as well as healthy people, and this in order to apply the program to larger groups. METHODS: From the residents' register of Foggia, a city in southern Italy, forty adults of both sexes, over 25 years of age, were recruited at random and assigned (1:1) as follows: - Twenty healthy subjects to the intervention-1 group - Twenty long-term cancer survivors to the intervention-2 group. The Med-Anticancer Food Program was applied to both groups with an articulated intervention 11 weeks long, followed by a 52-week period of follow up. By means of a food diary of the last 3 days, the Mediterranean Adequacy Index values were calculated before intervention (T0), after a period of 11 weeks of interventions (T1) and at the end of the 52 weeks of follow-up period (T2). The H0 hypothesis of the study was that there are no differences between the two interventions in reaching by T1, and maintaining at T2, values of Mediterranean Adequacy Index around 7, considered the optimum for adherence to the Mediterranean diet. RESULTS: Out of the subjects assigned to the intervention-1 group (n = 20), 11 subjects have completed the 52-months follow-up (55.0% ); for intervention-2, 16 (80%) out of 20 have completed it. The average age of subjects was 52.1 years. The Mediterranean Adequacy Index, of intervention-1 group significantly increased from 2.8 (T0) to 9.2 (T1) and to 9.0 (T2) (p <0.0001); whereas, in the intervention-2 group, Mediterranean Adequacy Index moved from 2.4 (T0) to 10.2 (T1) and to 9.3 (T2) (p <0.0001). The difference of Mediterranean Adequacy Index between the two study groups at T1 and T2 was not significant. Such non-significance persists also after the stratification by sex and age obtained with Mantel-Haenszel procedure. The performance of the values of the laboratory parameters considered (folic acid, total cholesterol, alkyl resorcinol) was similar in the subjects of both intervention 1 and 2, without any difference, while considered at a basal level T0, at T1 and at the end of the follow-up period (T2). CONCLUSIONS: The results of our work suggest the feasibility of conducting the Med-Anticancer Food Program in long-term cancer survivors. The results of the pilot study show that such intervention, carried on a small number of long term cancer survivors, is adequate to assess its feasibility but, due to the limited size of our study, a confirmation is required through larger nutritional prevention intervention studies.

RESUMEN

Every year the Italian Ministry of Health, on the basis of regional data, draws up the "Report on Official Controls" to be submitted to the Parliament. The report contains abundant data, diagrams and charts and illustrates the number and type of official controls (OC) performed by the pertinent Bodies (Ministry of Health, Regional and Local Health Authorities) over the previous year on Food Business Operators (FBO), in accordance with the EC Regulation 882/2004. The trend - which has consolidated over the years - relates to the multiplicity of OC and shows a decrease of such controls compared to an increase in "non-conformities". OC frequency is established by the Regional Authorities on the basis of the categorisation of both a "generic risk" for companies calculated taking into account the probability of occurrence of a "non-conformity", and a "specific" risk, assessed on the basis of the results of the OC actually performed on a given "Operatore del Settore Alimentare" (Food Sector Operator, in Italian: OSA). Thus, categorisation (i.e. the probability of occurrence of non-conformities) is the main driver of the OC scheduling and planning process. We have been asking ourselves whether the current OC planning/scheduling method is still suitable for ensuring food safety in the face of internalisation of the food supply chain. As a matter of fact, food safety is now becoming increasingly variable due to the globalization of consumption where "farm to fork", rather than "border to fork", food safety must be ensured. On the basis of these considerations, a different OC planning /scheduling method is being proposed based on the assessment of risks and the estimation of the occurrence of the same along the agro-food chain.

RESUMEN

The new research survey "Okkio alla salute", conducted in children in the 3rd year of elementary school, has confermed the worrisome phenomenon of the high number of obese and overweight children. Therefore, it is necessary, also in light of the few available resources, to fight back against this phenomenon that has been demonstrated to be a cause of disabling illnesses in adults. There must therefore be collaboration between Departments of Prevention and Hygiene and Nutrition services (SIAN) to build valid and efficient pathways. In this presentation we describe some national projects carried out by various local health agencies to address this health problem.

RESUMEN

Several studies have shown that uptake of a Mediterranean diet could prevent many chronic diseases, such as cancer. However, the effectiveness of Mediterranean diet promotion interventions has not been well researched. The aim of this study was to evaluate the effectiveness of a nutrition education intervention for promoting the Mediterranean diet, by assessing changes in anthropometric, physical activity, dietetic and metabolic parameters in healthy adult subjects, before and after the intervention. Eighty participants, both sexes, aged 51-59 years, were randomly assigned in a 1:1 ratio to the intervention or the control group. The intervention group participated in the Med-Food Anticancer Program (MFAP), designed to promote a Mediterranean diet. This was organized into 15 weeks of intensive training and 10 weeks of consolidation. Participants of the two groups were assessed at baseline (T0) and after 25 weeks (T1) for anthropometric, physical activity, dietetic, and metabolic parameters. The hypothesis was that subjects participating in MFAP would show an improvement in these parameters. The primary endpoint was an improvement of the Mediterranean Adequacy Index (MAI), calculated by dividing the percentage of total energy from typical Mediterranean food groups by the percentage of total energy from non-typical Mediterranean food groups. At T1, the intervention group showed a significant decrease in body weight (-8.3%, P = 0.045), body mass index (-12.4%, P = 0.05), cheese (53.0%, P < 0.0001) and meat (-49.3%, P = 0.005) intake, fasting glycaemia (-9.2%, P = 0.012), and fasting insulin (-32.6%, P = 0.014), C-Reactive Protein (-34.0%, P = 0.005). They showed a significant increase in MAI (+213, P < 0.0001), physical activity (expressed in steps per day, +200.4%, P < 0.0001), fruit (+38.8, P < 0.0001), vegetables (29.3%, P < 0.0001), and dietary fiber (+38.6%, P = 0.04) intake. In contrast, the control group presented non-significant variations in measured parameters, for exception of cheese intake (+18.2%, P < 0.0001). The MFAP was found to promote uptake of the Mediterranean diet, and improve anthropometric, physical activity, dietary, and metabolic parameters in healthy subjects.

RESUMEN

Several studies recommend the Mediterranean diet and daily physical activity to prevent cancer development. These recommendations, however must be transformed into public health structured programmes, so that they assume operational effectiveness. The aim of the diet and lifestyle intervention called Med-Food Anticancer Program (MFAP) is to promote the Mediterranean diet and physical activity in the adult population. In particular; the target for participants in the intervention is the increased consumption of legumes, fish, whole grain bread and cereals, fruits and vegetables, and the decreased consumption of meat, cheese and foods of animal origin. At the same time, it is recommended to make at least ten thousand steps a day. Two studies have shown the effectiveness of MFAP.

RESUMEN

Effectiveness comparison of different school-based nutrition education interventions to improve fruit and vegetable (F&V) consumption in schoolchildren not yet well researched. We evaluated the effectiveness of two school-based interventions promoting fruit and vegetable intake among Italian schoolchildren. In this randomized intervention trials, the first intervention was conducted by schoolteachers who attended a nutritionist-led training course (group-1), the second intervention conducted by schoolteachers who performed a self-training course (group-2). Thirty-two second to fifth-grade elementary classes enrolling 96 schoolteachers and 813 schoolchildren were randomized, and assigned to the two different nutrition education interventions. 804 students completed the study. By the end of the study, the group-1 (n = 409) followed by the teachers who attended a nutritionist-led course successfully increased the consumption of fruit and vegetables: in 183 (44.7%) and 157 (38.3%) schoolchildren respectively; the group-2 (n = 395) with teachers who performed a self-training course reported an increased consumption of fruit and vegetables in 81 (20.5%) and 76 (19.2%), respectively. This study indicates that a school-based nutrition education conducted by teachers who attended a nutritionist-led training course has a significant impact on primary school-age children's F&V intake.

RESUMEN

A short-version (15-week long) of school-based nutrition education program called "Bring Fruit to School" to enhance primary schoolchildren's fruit and vegetable (F&V) intake was evaluated. We recruited 199 primary schoolchildren from 8 classes (grade 2-5). The primary end-point was an increase in the children's F&V intake. The intervention period lasted 15 weeks, and was divided into three phases: weeks 1-5, weeks 6-10 and weeks 11-15. The F&V intake of the schoolchildren was also monitored in a subsequent follow-up period (16th-32nd week). By week 15, 92 (46.2%, P < .001) schoolchildren increase fruit intake and 91 (45.7%, P < .001) increase vegetable intake. The F&V intake increased during the intervention period and was constant in follow-up. The BFtS program is an effective means to promote primary schoolchildren's F&V intake, and was implemented in Italy by the Food and Nutrition Service of Foggia's Local Health Authority. It could be extended to many other countries by local nutrition agencies, such as associations for nutrition.

RESUMEN

The many nutrition education guidelines formulated by different organizations and institutions are the frames for the program actions targeting nutrition awareness in the school-age population. But while the guidelines represent a solid starting block they still need to be backed up by programs giving concrete form to the guiding principles, a program whose efficacy is demonstrated by specific applications studies. The aim of the "Bring Fruit at School" nutrition education program is to encourage elementary school children to change their eating habits for the better. And in particular to eat more fruit, vegetables, legumes, and fish and to cut down on junk-food and sugar-sweetened drink.

RESUMEN

New analogs of cyclic amino acid-conjugated bile acids were synthesized, and their physicochemical and biological properties were compared with those of natural analogs. Ursodeoxycholic acid was amidated with D-proline, L-proline, 4-hydroxy-L-proline, and 4-methoxy-L-proline. Hyocholic and hyodeoxycholic acids were amidated with L-proline. The physicochemical properties were similar to those of the natural analogs. All of them were highly stable toward enzymatic C-24 amide bond hydrolysis and 7-dehydroxylation. Their transport, metabolism, and effect on biliary lipid secretion were evaluated in bile fistula rat after intravenous infusion. All the analogs were secreted in bile unmodified. The 4-methoxy-L-proline derivative produced the highest secretion rate, much higher than those of all the other natural and synthetic analogs. This was associated with a selective reduction of cholesterol secretion with normal phospholipid secretion and choleresis. When coinfused, all the analogs were able to prevent the hepatotoxicity induced by intravenous taurochenodeoxycholic acid, as revealed by normal choleresis, alkaline phosphatase, and lactate dehydrogenase values in bile. Considering the overall data, 4-methoxy-L-proline, 4-hydroxy-L-proline, and L-proline derivatives of ursodeoxycholic acid were more potent than the natural analogs.

RESUMEN

In total, 5889 cases of hepatitis A virus infection were reported during an outbreak in Puglia, a region of Southern Italy, in 1996. The primary cause of the outbreak was consumption of contaminated food (raw shellfish, vegetables, etc.), with a contributory risk factor of person-to-person transmission. A detailed questionnaire was completed by 250 randomly selected patients to obtain information sufficient to calculate the direct and indirect costs of the outbreak for the individual patient, the National Health Service (NHS) and society as a whole. A conversion rate of $US1 = 1530 Italian lire (L) has been used throughout the study since this was the average exchange rate in 1996. For the individual patient with hepatitis A virus infection, the mean cost was L1.013 million ($US662), which was equivalent to 6.6% of the mean annual income of the employed patients. The total cost of the outbreak to the NHS was L23.98 billion ($US15.67 million), which was equivalent to 0.4% of the total public health expenditure in the region in 1996. The total cost of the outbreak to society (individual patient, NHS and third parties combined) was L37.406 billion ($US24.45 million), corresponding to 0.04% of the gross domestic product of the entire region in 1996, with a mean cost per patient of L6.35 million ($US4150) from a societal perspective. The majority of patients (86.3%) were 11 to 30 years of age, reflecting the increasing susceptibility of younger patients to hepatitis A virus infection in recent decades. These economic and demographic data provide important information for the evaluation of preventive strategies including public education, sanitation and immunisation, so as to optimise the use of local health resources.

RESUMEN

Antimutagens and anticarcinogens are known to play an important role in decreasing damages induced by oxidants. In this study, we investigated the genotoxic and antimutagenic potential of two selenium compounds (sodium selenite: Na(2)SeO(3); seleno-DL-methionine: C(5)H(11)NO(2)Se) and Vitamins A and E in yeast cells of Saccharomyces cerevisiae. An oxidative mutagen (hydrogen peroxide (H(2)O(2)), HP) was chosen as positive control. We determined the enzymatic activities involved in the protection against oxidative damages (catalase: CAT; superoxide dismutase: SOD; glutathione peroxidase: GPx) in the cytosolic extract of yeast cells. The results demonstrated that selenium compounds exerted both mutagenic and antimutagenic effect at different concentrations. Antimutagenesis was evident both in stationary and in logarithmic phase cells. Catalase, SOD, and GPx were significantly increased in the presence of all the compounds assayed. Vitamins A (retinol) and E (alpha-tocopherol) did not have toxic or mutagenic action.

RESUMEN

Leishmania infantum is the causative agent of canine leishmaniasis in the Mediterranean area. The aspects of the canine immune response which may explain the chronic severe disease in these animals have not been well investigated. Therefore, in this work we have evaluated the parasite killing ability by circulating polymorphonuclear (PMN) cells and monocytes in dogs with spontaneous leishmaniasis and in healthy dogs. Moreover, in order to analyse the mechanisms responsible for killing activity, we evaluated the oxidative burst of circulating PMN cells, in terms of O2- and H2O2 production. The killing ability of infected dog PMN cells and monocytes was significantly lower than in a group of healthy dogs and a group of infected dogs treated with meglumine antimoniate and without symptoms of leishmaniasis. Superoxide anion and hydrogen peroxide production by PMN cells was significantly lower in a group of Leishmania-infected dogs than in healthy dogs, suggesting that these mediators may be involved in the reduced killing activity of infected dogs.

RESUMEN

Magnesium is a microelement that is essential for biological functions and particularly for cellular metabolism. It has a central role in protein, lipid, carbohydrate, and nucleic acid synthesis, and it is important for muscular physiology and nerve excitability. Magnesium has an important role in the stability of biological membranes, it controls immune phenomena, and it activates over 300 enzymes. However, the mechanism of action of magnesium salts has not been well investigated and, in particular, its antimutagenesis properties and its effects in the detoxification of free radicals need further study. We investigated the effect of magnesium chloride, sulphate, carbonate, and oxide on the yeast Saccharomyces cerevisiae D7 strain, to evaluate their ability to protect against genotoxic damage. We found that magnesium salts induced antimutagenic effects in the cells harvested in the logarithmic phase by decreasing the induction of hydrogen peroxide. This, however, did not occur in the stationary phase. We also studied calcium salts of the type corresponding to those of magnesium and their protective role against the oxidative damage of free radicals and enzymatic activities, such as catalase, glutathione peroxidase, and superoxide dismutase, which are involved in antioxidative defenses.

RESUMEN

The introduction of antibiotics to treat bacterial infections either by killing or blocking their growth has been accompanied by the development of resistance mechanism that allows the bacteria to survive and proliferate. In particular the successive series of ß-lactams have selected several generations of ß-lactamases including ESBLs, AmpC ß-lactamases, KPC carbapenamases in Enterobacteriaceae, the metallo ß-lactamases VIMs and IMPs, and very recently the threatening NDM-1 that confers resistance to virtually any clinically used antibiotic. The increasing use of carbapenems due to the spread of resistance to other existing antibacterial agents has facilitated the spread of resistance, especially in Acinetobacter spp. due to OXA- and metallo-carbapenemases. The pharmaceutical industry, that abandoned this field at the end of the nineties, is now trying to recover by developing some novel ß-lactam antibiotics and novel ß-lactamase-inhibitors, the latter to be used in combination with new as well as seasoned ß-lactam antibiotics. This article provides a survey of patent and scientific literature for ß-lactamase inhibitors discovered in the period 2006-2010.

RESUMEN

The aim of this article is to retrospectively evaluate the patient characteristics and the most common infectious diseases in immigrant patients hospitalized in 46 Italian infectious disease clinics during 2002. The main Italian infectious disease clinics were invited to fill in a questionnaire that regarded the number and type of hospital admissions, the country of origin, and demographic features (age, sex, and resident state) of immigrants. A total of 46 clinics including 2255 patients participated in the study. Most patients were men (63%) with an age between 16 and 40 years (63.4%) covered by the National Health Service (71%) and coming from Africa (44.3%). The main infectious diseases observed were: 378 (16.76%) cases of HIV infection, 303 (13.43%) cases of tuberculosis diseases, 282 (12.5%) cases of various forms of viral hepatitis, 177 (7.84%) cases of respiratory diseases, and 196 (8.69%) gastrointestinal diseases. Tropical diseases found were 134 (5.94%) including 95 cases of malaria (70.9%). In conclusion, a broad range of diseases was noted in immigrants which were directly correlated with conditions of poverty. Only a few tropical diseases were diagnosed and therefore the immigrant should not be considered as an infectious disease carrier.

RESUMEN

Protozoan parasites of the Leishmania genus are the causative agents of important diseases in humans and animals. During their life cycle in vertebrate hosts, protozoa are able to live and proliferate within phagolysosomes of host phagocytic cells. The capacity to live in this hostile environment is likely due to the cell surface glycoconjugate expression. In particular, lipophosphoglycan (LPG), a major surface glycoconjugate of Leishmania promastigotes, has been reported to play an active role in protecting parasites within phagolysosomes via the impairment of killing mechanisms. In this review, the authors emphasize some novel LPG-mediated escape mechanisms of promastigotes from human phagocyte responses, such as the impairment of oxidative burst and of chemotactic activity. In the light of these findings, the knowledge of biological actions of LPG may be useful in order to prepare a vaccine against human leishmaniasis, using LPG defective avirulent mutant strains.

RESUMEN

The support of a delicate reagent on a solid matrix allows for better and safer handling of the reagent itself. Because we had an interest in silicon-based supported reagents(1) we turned our attention to a polymer-supported trialkylsilyl cyanide and trialkylsilyl azide starting from a commercially available trialkylsilane resin. The supported cyanide was obtained with excellent yield and proved to be shelf-stable. This supported reagent was reacted with a series of aldehydes and ketones yielding the corresponding polymer-supported cyanohydrins in good-to-excellent yields. A stability study on a model cyanohydrin demonstrated that these supported intermediates also can be stored for a prolonged time. For the last step, a cleavage strategy that could release either cyanohydrins or alpha-hydroxy esters was adopted. Finally, we prepared a polymer-supported trialkylsilyl azide, which also proved to be shelf-stable.
