RESUMO

Background: The drinking of bottled water has remarkably increased at a global scale even in the regions possessing other adequate water sources. This study elaborates on the factors influencing the consumption of tap, filtered, and bottled water in the Kingdom of Bahrain and on the environmental consequences of bottled water consumption. Methods: A cross-sectional study was performed on 483 participants in the Kingdom of Bahrain between April and May 2019. A questionnaire-based survey was conducted to assess the preferred water type, to estimate the amount of bottled water consumption per year/capita, and other water consumption-related information. Results: The study revealed that filtered (35.90%) and bottled (34.50%) waters were predominantly consumed in the Kingdom, while the consumption of tap water was negligible (8.90%). The total consumption of bottled water was 0.51 liters/day, which is equivalent to 184.69 liters/year. Thus, 295.50 liters/capita/year of bottled water were consumed based on the approximate 1.6 million population in 2019. This consumption rate is extremely high in comparison to other countries. Conclusions: The study recommended improving population satisfaction of tap water, conducting tap water marketing campaigns, investments in recycling infrastructures, and introducing educational plans to properly dispose of water bottles.

RESUMO

BACKGROUND: Since the use of medicines is strongly correlated to population health needs, higher drug consumption is expected in socio-economical deprived areas. However, no systematic study investigated the relationship between medications use in the treatment of chronic diseases and the socioeconomic position of patients. The purpose of the study is to provide a description, both at national level and with geographical detail, of the use of medicines, in terms of consumption, adherence and persistence, for the treatment of major chronic diseases in groups of population with different level of socioeconomic position.  METHODS: A cross-sectional study design was used to define the "prevalent" users during 2018. A longitudinal cohort study design was performed for each chronic disease in new drug users, in 2018 and the following year. A retrospective population-based study, considering all adult Italian residents (i.e. around 50.7 million people aged ≥ 18 years). Different medications were used as a proxy for underlying chronic diseases: hypertension, dyslipidemia, osteoporosis, diabetes and chronic obstructive pulmonary disease. Only "chronic" patients who had at least 2 prescriptions within the same subgroup of drugs or specific medications during the year were selected for the analysis. A multidimensional measures of socio-economic position, declined in a national deprivation index at the municipality level, was used to identify and estimate the relationship with drug use indicators. The medicine consumption rate for each pharmacological category was estimated for prevalent users while adherence and persistence to pharmacologic therapy at 12 months were evaluated for new users. RESULTS: The results highlighted how the socioeconomic deprivation is strongly correlated with the use of medicines: after adjustment by deprivation index, the drug consumption rates decreased, mainly in the most disadvantaged areas, where consumption levels are on average higher than in other areas. On the other hand, the adherence and persistence indicators did not show the same trend. CONCLUSIONS: This study showed that drug consumption is influenced by the level of deprivation consistently with the distribution of diseases. For this reason, the main levers on which it is necessary to act to reduce disparities in health status are mainly related to prevention. Moreover, it is worth pointing out that the use of a municipal deprivation indicator necessarily generates an ecological bias, however, the experience of the present study, which for the first-time deals with the complex and delicate issue of equity in Italian pharmaceutical assistance, sets the stage for new insights that could overcome the limits.

RESUMO

Objectives: The severe acute respiratory syndrome (COVID-19) due to SARS-CoV-2 was first reported in China in December 2019 and has generated a worldwide pandemic. The objective of the research is to examine and describe (a) the symptoms that persist after the end of the acute stage and (b) their relationship with the severity of the disease. Study Design: This study is a cross-sectional study conducted in the Kingdom of Bahrain on COVID-19 infected patients using an online survey questionnaire with a total number of 52 patient responses (29 females and 23 males). Method: A scale (0 no symptoms to 10 very high symptoms intensity) was assessed in patients after 3 months to detect the relevance of specific symptoms post-COVID-19 such as emotional and physical health, headache, dyspnoea, pain (muscles/joints/chest), anosmia, vertigo, neurologic symptoms, sarcopenia, delirium. Results: The most common COVID-19 symptoms were reported to be fever (69.2%), headache (59.6%), and cough (50.0%). Data analysis showed that BMI was not correlated with any post-acute COVID-19 symptoms. Regarding the post-acute COVID-19 symptoms, this study showed that an increase of intensity of headache was associated with an increase of delirium; an increase of intensity of dyspnoea was associated with an increase of pulmonary dysfunction. The increase of anosmia and dysgeusia was associated with an increase in delirium. In addition, the increase of neurological symptoms and delirium were associated with the increase of sarcopenia. The most common persistent post-COVID-19 symptoms observed in this study were emotional stress, followed by loss of smell and taste, and neurological symptoms. Conclusions: Therefore, follow-up and rehabilitation care for COVID-19 patients must be focused on addressing the needs of these people in the longer term.

RESUMO

Background: The severe, acute respiratory syndrome COVID-19 that was first reported in China in December 2019 quickly became a global pandemic that has resulted in over 100 million infections and more than 2 million deaths. Study Design: This study aimed to assess the awareness level of university students regarding the possibility of becoming infected with COVID-19. In order to achieve this objective, we assessed the students' knowledge, attitudes, and behaviors using an online survey questionnaire offered to a total of 300 students. Results: A positive response regarding awareness of COVID-19 symptoms was registered by more than 70% of the students, whereas 62% felt that wearing a mask did not give full protection against infection, approximately 30% agreed that antibiotics and antivirals did not treat COVID-19, and 62% agreed that vitamin C was helpful in treating common symptoms of COVID-19. Moreover, around 31% of the students believed that COVID-19 is a man-made virus. Students who had gotten infected with SARS-CoV-2 believed that wearing a mask gives full protection (p=0.018). In response to survey questions related to attitude, 80% of students cancelled and postponed meetings with friends, and 90% agreed that mask-wearing is the most precautionary measure used to prevent the infection. In addition, 82% avoided coughing in public, 82% avoided contact if they felt flu-like symptoms and 80% washed their hands far more often due to the pandemic. Interestingly, 76% carried hand sanitizer, 66.5% avoided shaking hands, and 42.7% were taking vitamin C supplements. Conclusions: This study showed that the participants had a positive awareness of COVID-19 transmission, symptoms, and treatments misconceptions and mistaken beliefs related to treatments and the origin of the virus were also common and should be addressed. This study thus provides a baseline for a population-based surveillance program that could help local authorities to improve pandemic preparation plans, particularly with regard to governmental education and media campaigns.

RESUMO

PURPOSE: The therapy of polycystic ovary syndrome (PCOS) is based on synthetic hormones associated with lifestyle changes, but these therapies cannot be taken continuously, especially by women who would like to become pregnant. Thus, nutraceutical compounds were investigated as possible agents for treatment of PCOS. Berberine is shown to be effective against insulin resistance and obesity, particularly against visceral adipose tissue (VAT). Because of these properties, researchers theorized that berberine could be effective in PCOS treatment. METHODS: The aim of this narrative review was to assess the state of the art about the use of berberine in PCOS management. RESULTS: This review included 5 eligible studies. Despite the number of studies considered being low, the number of women studied is high (1078) and the results are interesting. Two authors find out that berberine induced a redistribution of adipose tissue, reducing VAT in the absence of weight loss and improved insulin sensitivity, quite like metformin. One author demonstrated that berberine improved the lipid pattern. Moreover, three authors demonstrated that berberine improved insulin resistance in theca cells with an improvement of the ovulation rate per cycle, so berberine is also effective on fertility and live birth rates. CONCLUSIONS: Finally, berberine is safe to use in premenopausal women who want to get pregnant and showed few side effects in all the cited studies. In conclusion, the use of berberine for PCOS is safe and promising, even if more studies are needed to create a consensus about the dosage of berberine useful for long-term therapy.

RESUMO

BACKGROUND: Anorexia of ageing (AA) may be considered as a risk factor for frailty and has an important impact on quality of life, morbidity and mortality. METHODS: A systematic review and a meta-analysis were performed to summarise the results from several trials on the effectiveness of treatments in AA, as associated with depression, sensory impairment of taste and smell, decreased appetite or early satiety, and disability. Eligible studies were required to report baseline and follow-up values, the mean change (∆-change) from baseline, and/or the mean difference among intervention groups versus control group, concerning food intake (kcal/daily) and/or nutritional outcomes, such as body weight, body mass index, albumin and Mini Nutritional Assessment. RESULTS: The systematic review included 20 papers based on different therapeutic approaches concerning food intake and/or nutritional outcomes. The results of the meta-analysis indicate that the interventions for AA have an important impact on body weight [+1.59 kg; 95% confidence interval (CI) = 1.48-+1.71 kg; P < 0.001) and on energy intake (+56.09 kcal; 95% CI = -54.05 to +166.25 kcal; P = 0.32). Regarding secondary outcomes, it was not possible to meta-analyse the limited amount of data availab le. CONCLUSIONS: The different variants of AA need to be defined because diverse therapeutic approaches are available. A more precise definition of the functional impairments associated with AA may allow a more correct decision about the most appropriate therapy to be prescribed. Moreover, this may allow for a more effective performance of the different therapeutic approaches once they are better targeted to the different scenarios of AA.

RESUMO

Yogurt is a good source of probiotics, calcium, and proteins, but its content of vitamin D is low. Therefore, yogurt could be a good choice for vitamin D fortification to improve the positive health outcomes associated with its consumption. The primary aim of this systematic review and meta-analysis was to investigate the effect of vitamin D-fortified yogurt compared with plain yogurt on levels of serum 25-hydroxy vitamin D (25OHD). The secondary aim was to evaluate the effect of fortified yogurt on parathyroid hormone, anthropometric parameters, blood pressure, glucose metabolism, and lipid profile. We searched PubMed, Scopus, and Google Scholar for eligible studies; that is, randomized controlled trials (RCT) that compared vitamin D-fortified yogurt with control treatment without any additional supplement. Random-effects models were used to estimate pooled effect sizes and 95% confidence intervals. Findings from 9 RCT (n = 665 participants) that lasted from 8 to 16 wk are summarized in this review. The meta-analyzed mean differences for random effects showed that vitamin D-fortified yogurt (from 400 to 2,000 IU) increased serum 25OHD by 31.00 nmol/L. In addition, vitamin D-fortified yogurt decreased parathyroid hormone by 15.47 ng/L, body weight by 0.92 kg, waist circumference by 2.01 cm, HOMA-IR by 2.18 mass units, fasting serum glucose by 22.54 mg/dL, total cholesterol by 13.38 mg/dL, and triglycerides by 30.12 mg/dL compared with the controlled treatments. No publication bias was identified. Considerable between-study heterogeneity was observed for most outcomes. Vitamin D-fortified yogurt may be beneficial in improving serum 25OHD, lipid profile, glucose metabolism, and anthropometric parameters and decreasing parathyroid hormone level in pregnant women and adult and elderly subjects with or without diabetes, prediabetes, or metabolic syndrome.

RESUMO

We compare bioimpedance analysis (BIA) with dual-energy X-ray absorptiometry (DXA) in the assessment of free fat mass (FFM), fat mass (FM) and percentage of body fat under different conditions in relation to age categories, hydration parameters, body mass index (BMI) and sarcopenia. A cross-sectional analysis of body composition was estimated by BIA and DXA in 379 hospitalized elderly patients. In addition, estimates of FFM, FM and percentage of body fat were investigated across different conditions. Paired t-tests, Bland-Altman plot and intraclass correlation coefficient analysis were used to compare methods. Data showed an underestimation of means (BIA versus DXA) of FFM (women: 0,97 kg, p<0,01; men: 1,99 kg; p<0,01), and an overestimation of both the FM (women: +1,11 kg; p<0,01; men: +1,67 kg; p<0,01) and percentage of body fat (women: +2,07 %, p<0,01; men: +2,82 %, p<0,01). BIA underestimated FFM and overestimated FM and percentage of body fat in patients from the age group of 75 to 85 years, in patients with a total body water content <60%, in underweight and normal weight patients and in patients with sarcopenia (p<0,01). The intraclass coefficient results were indicative of poor reproducibility between BIA and DXA for FFM (women: +0,197; men: +0,250) and FM (women: +0,141; men +0,144). BIA is a good alternative for estimation of FFM and FM only in overweight or obese patients or in patients with good hydration status. BIA, on the other hand, is not an accurate method for assessing FFM in sarcopenic patients.

RESUMO

BACKGROUND: In early childhood, the allergen-specific IgG repertoire is mainly directed to animal and vegetable food molecules and infrequently to airborne molecules. It is unknown whether this early pattern is maintained throughout childhood. OBJECTIVE: To investigate the evolution of IgG and IgE responses to a broad panel of allergenic molecules from birth to age 10 years. METHODS: We examined the sera collected between birth and age 10 years from participants in the German Multicentre Allergy Study, a birth cohort born in 1990. The IgE (cutoff ≥0.30 ISU) and IgG (cutoff ≥0.10 ISU) responses to 35 genuine allergenic molecules were measured with a multiplex microarray approach (ImmunoCAP ISAC™). RESULTS: IgE responses were mostly directed against a restricted group of airborne molecules, with a sequence and prevalence hierarchy (Phl p 1> Bet v 1> Fel d 1> Phl p 5> Der p 2> Der p 1) largely maintained over time. Conversely, the IgG repertoire was much broader, starting with animal foodborne, then spreading to vegetable foodborne and finally to airborne molecules. A strong and persistent IgG response to a given airborne molecule almost invariably preceded or accompanied an IgE response to that molecule. CONCLUSIONS: The evolution of IgG and IgE responses throughout childhood differs widely at population level. IgG responses are mostly directed to animal food allergens, while IgE responses are dominated by airborne allergens. However, a strong IgG response almost invariably precedes or accompanies the appearance of IgE to the same molecule in specifically sensitized subjects.

RESUMO

BACKGROUND: Grass pollen-related seasonal allergic rhinoconjunctivitis (SARg) is clinically heterogeneous in severity, comorbidities, and response to treatment. The component-resolved diagnostics disclosed also a high heterogeneity at molecular level. Our study aimed at analyzing the characteristics of the IgE sensitization to Phleum pratense molecules and investigating the diagnostic relevance of such molecules in childhood. METHODS: We examined 1120 children (age 4-18 years) with SARg. Standardized questionnaires on atopy were acquired through informatics platform (AllergyCARD™). Skin prick tests were performed with pollen extracts. Serum IgE to airborne allergens and eight P. pratense molecules (rPhl p 1, rPhl p 2, rPhl p 4, rPhl p 5b, rPhl p 6, rPhl p 7, rPhl p 11, rPhl p 12) were tested by ImmunoCAP FEIA. RESULTS: The analysis of IgE responses against eight P. pratense molecules showed 87 profiles. According to the number of molecules recognized by IgE, the more complex profiles were characterized by higher serum total IgE, higher grass-specific serum IgE, and higher number and degree of sensitization to pollens. The most frequent IgE sensitization profile was the monomolecular Phl p 1. Sensitization to Phl p 7 was a reliable biomarker of asthma, whereas Phl p 12 of oral allergy syndrome. Sensitization to Phl p 7 was associated with a higher severity of SARg, and complex profiles were associated with longer disease duration. CONCLUSIONS: In a large pediatric population, the complexity of IgE sensitization profiles against P. pratense molecules is related to high atopic features although useless for predicting the clinical severity. The detection of serum IgE to Phl p 1, Phl p 7, and Phl p 12 can be used as clinical biomarkers of SARg and comorbidities. Further studies in different areas are required to test the impact of different IgE molecular profiles on AIT response.

RESUMO

PURPOSE: To investigate the association between fasting glucagon-like peptide 1 (GLP-1) levels and resting energy expenditure (REE), and respiratory quotient (RQ) in overweight and obese adults. METHOD: Study participants were enrolled at the Dietetic and Metabolic Unit, University of Pavia, Italy. Inclusion criteria were age ≥ 25 and ≤ 45 years, and body mass index (BMI) ≥ 25 and ≤ 35 kg/m2. Diabetic subjects were excluded. Body composition was measured by dual-energy X-ray absorptiometry. REE was evaluated using indirect calorimetry, and RQ was calculated from respiratory gas exchanges. Fasting GLP-1, glucose, insulin and free fatty acid (FFA) levels, and 24-h norepinephrine urinary excretion were measured. Homeostasis model assessments of insulin resistance (HOMA-IR) and beta-cell function (HOMA-ß) were calculated. RESULTS: Thirty-seven participants were included (age 43.4 ± 1.6 years; BMI 30.6 ± 0.5 kg/m2). REE was not associated with fasting GLP-1 levels (p = 0.98) after adjustment for age, sex, fat-free mass (FFM), and fat mass (FM). Similarly, no association was observed between RQ and GLP-1 levels (p = 0.95), after adjustment for age, sex, and body fat. CONCLUSION: In adults subjects with increased adiposity fasting, GLP-1 levels do not seem to play a role in the regulation of energy metabolism and in fuel selection.

RESUMO

Due to an increasingly aging population, Alzheimer disease (AD) represents a crucial issue for the healthcare system because of its widespread prevalence and the burden of its care needs. Several hypotheses on AD pathogenesis have been proposed and current therapeutical strategies have shown limited effectiveness. In the last decade, more evidence has supported a role for neuroinflammation and immune system dysregulation in AD. It remains unclear whether astrocytes, microglia and immune cells influence disease onset, progression or both. Amyloid-ß peptides that aggregate extracellularly in the typical neuritic plaques generate a constant inflammatory environment. This causes a prolonged activation of microglial and astroglial cells that potentiate neuronal damage and provoke the alteration of the blood brain barrier (BBB), damaging the permeability of blood vessels. Recent data support the role of the BBB as a link between neuroinflammation, the immune system and AD. Hence, a thorough investigation of the neuroinflammatory and immune system pathways that impact neurodegeneration and novel exciting findings such as microglia-derived microvesicles, inflammasomes and signalosomes will ultimately enhance our understanding of the pathological process. Eventually, we should proceed with caution in defining a causal or consequential role of neuroinflammation in AD, but rather focus on identifying its exact pathological contribution.

RESUMO

BACKGROUND: Pollen-food syndrome (PFS) is heterogeneous with regard to triggers, severity, natural history, comorbidities, and response to treatment. Our study aimed to classify different endotypes of PFS based on IgE sensitization to panallergens. METHODS: We examined 1271 Italian children (age 4-18 years) with seasonal allergic rhinoconjunctivitis (SAR). Foods triggering PFS were acquired by questionnaire. Skin prick tests were performed with commercial pollen extracts. IgE to panallergens Phl p 12 (profilin), Bet v 1 (PR-10), and Pru p 3 (nsLTP) were tested by ImmunoCAP FEIA. An unsupervised hierarchical agglomerative clustering method was applied within PFS population. RESULTS: PFS was observed in 300/1271 children (24%). Cluster analysis identified five PFS endotypes linked to panallergen IgE sensitization: (i) cosensitization to ≥2 panallergens ('multi-panallergen PFS'); (ii-iv) sensitization to either profilin, or nsLTP, or PR-10 ('mono-panallergen PFS'); (v) no sensitization to panallergens ('no-panallergen PFS'). These endotypes showed peculiar characteristics: (i) 'multi-panallergen PFS': severe disease with frequent allergic comorbidities and multiple offending foods; (ii) 'profilin PFS': oral allergy syndrome (OAS) triggered by Cucurbitaceae; (iii) 'LTP PFS': living in Southern Italy, OAS triggered by hazelnut and peanut; (iv) 'PR-10 PFS': OAS triggered by Rosaceae; and (v) 'no-panallergen PFS': mild disease and OAS triggered by kiwifruit. CONCLUSIONS: In a Mediterranean country characterized by multiple pollen exposures, PFS is a complex and frequent complication of childhood SAR, with five distinct endotypes marked by peculiar profiles of IgE sensitization to panallergens. Prospective studies in cohorts of patients with PFS are now required to test whether this novel classification may be useful for diagnostic and therapeutic purposes in the clinical practice.

RESUMO

BACKGROUND: Adherence to controller therapy in allergic diseases is low. Telemonitoring has been proposed to improve adherence to treatment in chronic diseases. However, this strategy has never been tested in allergic rhinoconjunctivitis. OBJECTIVE: To test whether Internet-based telemonitoring during the grass-pollen season of children with allergic rhinoconjunctivitis may enhance adherence to treatment. METHODS: Children and adolescents, 5-18 years old, with moderate-to-severe seasonal allergic rhinoconjunctivitis to grass pollen requiring daily administration of nasal corticosteroid (NCS) (mometasone) were recruited (April 2013) in a paediatric allergy practice. Participants were randomized to Internet-based monitoring (AllergyMonitor(™) , AM) or to usual care (no diary at all, controls) and followed from 13 May (T0) to 15 June 2013 (T2). An intermediate visit (T1) was performed between 31 May and 2 June. Optimal adherence to therapy was expressed as the use of at least 0.190 g/day of mometasone, corresponding to 1 puff/nostril/day, and it was measured by canister weights during (T1) and at the end (T2) of the study period. Main secondary outcomes included the reported disease severity (validated self-questionnaire) and quality of life (AdoIRQLQ questionnaire), disease knowledge (multiple-choice questionnaire), nasal flow and resistance at baseline and at T2. RESULTS: The use of mometasone, expressed as both optimal adherence rate (48.4% vs. 12.5%; P = 0.002) and average daily use (0.20 ± 0.12 g/day vs. 0.15 ± 0.07 g/day; P = 0.037), was higher in the AM group (n = 31) than among controls (n = 32). Disease knowledge improved among the patients using AM (83.3% vs. 68.3%; P < 0.001) but not among controls (68.2% vs. 67.7% right answers; P > 0.05). No differences were observed in the reported severity of disease, nasal flow and resistance and quality of life both at baseline and at follow-up visits. CONCLUSIONS: Internet-based telemonitoring improves adherence to NCS treatment and disease knowledge among children and adolescents with seasonal allergic rhinoconjunctivitis.

RESUMO

A one-dimensional continuum-mechanical model of axonal elongation due to assembly of tubulin dimers in the growth cone is presented. The conservation of mass leads to a coupled system of three differential equations. A partial differential equation models the dynamic and the spatial behaviour of the concentration of tubulin that is transported along the axon from the soma to the growth cone. Two ordinary differential equations describe the time-variation of the concentration of free tubulin in the growth cone and the speed of elongation. All steady-state solutions of the model are categorized. Given a set of the biological parameter values, it is shown how one easily can infer whether there exist zero, one or two steady-state solutions and directly determine the possible steady-state lengths of the axon. Explicit expressions are given for each stationary concentration distribution. It is thereby easy to examine the influence of each biological parameter on a steady state. Numerical simulations indicate that when there exist two steady states, the one with shorter axon length is unstable and the longer is stable. Another result is that, for nominal parameter values extracted from the literature, in a large portion of a fully grown axon the concentration of free tubulin is lower than both concentrations in the soma and in the growth cone.

RESUMO

The management of overweight may include the use of dietary supplements targeted to counter the feeling of hunger. A randomized, double-blind, placebo-controlled trial has been performed in 20 overweight females. These subjects were randomly assigned to supplement their diet with either an extract from Griffonia Simplicifolia (10 subjects) or a placebo (10 matched subjects) for 4-weeks, in conjunction with a personalised reduced calorie diet. The main aim of this study was to evaluate the efficacy, by the assessment of 24-h urinary 5-hydroxyindoleacetic acid levels (5-HIAA), of 1-month administration of a dietary supplement containing 5-hydroxytryptophan (5-HTP) from botanical extracts in healthy, overweight females. Secondary endpoints were the assessment of sensation of appetite (by Haber score), body composition, and severity of binge eating. The supplemented group had a significant increase of 24-h urinary 5-HIAA levels (p<0.001), and a decrease in Haber score (p<0.001) while the placebo group did not show significant changes. With regard to changes in body composition, statistically significant differences between the treatment groups were found for the mean change in BMI, suprailiac skinfold thicknesses, arm circumference and hip circumference. Other parameters were found to be similar in the treated and in the placebo groups. In conclusion, this study shows that the 5-hydroxytryptophan present in the Griffonia extract, administered via spray to the oral cavity, is adequately absorbed, as confirmed by the increase in 24-h urinary 5-HIAA, and that the supplementation of the diet of overweight women with 5-hydroxytryptophan increases the feeling of satiety associated with a decrease in BMI.

RESUMO

BACKGROUND: Peloid has been popularly used as an effective base in cosmetic preparations, although its biologically-active materials and mechanisms on skin have not yet been fully determined. An association between Massaciuccoli peat and sodium chloride water of Undulna Thermae was evaluated as a 2-weeks therapy for gynoid lipodystrophy in a group of 30 overweight females (age: 20-50y, BMI: 25-35 kg/m2) by means of evidence based-medicine criteria. METHODS: The modification of the body diameters was the primary end-point, and the variation of skinfold thicknesses, bioimpendance parameters, evaluation of skin elasticity, rated thermal contact to liquid crystals and measurement of subcutaneous fat tissue were the secondary end-points. It was asked, by visual-analog scale, for an opinion to the patients about effectiveness of treatment. RESULTS: At the end of treatment, after 2 weeks, all body diameters significantly decreased in the intervention group (waist circumference: 91.95 +/- 8.94 versus 90.60 +/- 8.90 cm, p < 0.001). Moreover, total body water were significantly reduced in the intervention group (35.05 +/- 3.74 versus 34.38 +/- 3.41 l, p < 0.03). As regards skin elasticity (+5.52%, p < 0.001), significant improvements have been determined; subcutaneous perfusion was also improved and thickness of subcutaneous fat was significantly reduced (thighs delta = -1.3 mm, p < 0.01; abdomen delta = -4.6 mm, p < 0.001). Furthermore, response to the visual-analog scale was positive (7.55 +/- 0.87). CONCLUSIONS: This treatment appears potentially useful in the clinical management of gynoid lipodystrophy in overweight females.

RESUMO

In recent decades, the American diet has emerged in our country as a reference model food, particularly among young people, to the detriment of the Mediterranean diet, an healthy eating pattern rich in fruits and vegetables, olive oil, whole grains and fish. Even in Europe, North American habits are widespread at the expense of traditional northern nutritional powers, characterized by a lot of fish, wild game meat that are much thinner than from farm animals, rye, oats, cabbage, root vegetables. Given this background, in Pavia (Italy) and Tampere (Finland) we conducted a pilot study with the objective to assess and compare the eating habits and nutrition knowledge in school-age children using 2 questionnaires entitled "what do you eat?" and "what do you know about diet and health?". The results of the first questionnaire clearly shows that, among young people of both countries, there is the loss of traditional food: the Mediterranean and the Finnish diet. All the boys wear it with a low frequency fish, fruit and vegetables, and instead a high frequency of adverse health foods, such as potato chips and sweet drinks. The answers to questions which relate to nutrients and their properties, show that children of all groups have little knowledge about these topics. The use of questionnaires, such as those administered by us, can be easily performed to investigate the dietary habits and the nutritional level of culture, due to make nutrition education interventions aimed at correcting poor eating habits.
