Background: HCV-related extra-hepatic complications include peripheral neuropathies, with important prevalence and impact. A recent metanalysis of previous intervention trials concluded for insufficient data to support evidence-based treatments for this complication. In this longitudinal study, we assessed for the first time prevalence and outcome of neuropathy in a cohort of patients with chronic HCV, before and after direct-acting antiviral agent (DAA) treatment., Method: Ninety-four patients (mean age 58.5 ± 9.9, infection duration 22.2 ± 6.3 years) without systemic and metabolic diseases, underwent neurological examination and electroneurography studies before (T0) and 10.4 ± 1.7 months after the end of DAA therapy (T1), and cryoglobulins (CG) assessment. Muscle strength was evaluated by Medical Research Council (MRC) score; neuropathic pain, sensory function, disability, quality of life were assessed by validated questionnaires (DN4, NPSI, SSS, INCAT and Euro-QoL)., Results: At T0, sensory-motor neuropathy was detected in 22 patients (23%), reflexes were depressed in 32 (34%) with no association with infection duration, viral load, age, CG. Neuropathic pain (DN4 ≥4) was present in 37 patients (39%). At T1, out of the 22 patients with altered electroneurography, 3 had died or developed HCC, 4 showed normal electroneurography, and nerve amplitude parameters tended to improve in the whole group. Only 11 patients (12%) had depressed reflexes and 10 (11%) DN4 ≥4 (P < .05 compared to T0). Scores for MRC, questionnaires and Euro-QoL improved significantly (P < .05)., Conclusion: Our study confirms the high prevalence of clinical and subclinical peripheral sensory-motor neuropathy in patients with HCV infection and indicates improvement after eradication by DAA. These results support the need for larger intervention studies., (© 2021 The Authors. Liver International published by John Wiley & Sons Ltd.)

Background: Glycogen in skeletal muscle is a major source of energy during exercise and an important determinant of endurance capacity, so that its measurement may provide a meaningful marker of athletes' preparation and a possible predictor of performance, both in humans and in equines. Gold standard of glycogen concentration measurement is the histochemical and biochemical analysis of biopsy-derived muscle tissue, an invasive and potentially injuring procedure. Recently, high-frequency ultrasound (US) technology is being exploited in human sports medicine to estimate muscle glycogen content. Therefore, aim of the present study is to evaluate the feasibility of US assessment of muscle glycogen in equines., Results: US images of gluteus medius (GL) and semitendinosus (ST) muscles were obtained on eight healthy horses (3-10 years) before and after a steady-state exercise on treadmill (velocity: 4.0-12.5 m/s; duration: 2-20 min; heart rate: 137-218 b/min). Average image greyscale intensity was significantly different between GL and ST, both before and after exercise (p < 0.001). Comparing baseline and post-exercise US images, significant increase in greyscale intensity has been observed in ST (p < 0.001), but not in GL (p = 0.129). The volume of the exercise was significantly correlated with exercise-dependent change in image intensity (R 2  = 0.891), consistent with a reduction of glycogen muscle stores resulting from aerobic activity., Conclusions: US technique evidences also in horses muscle changes possibly associated to glycogen utilisation during exercise. Present results on a small sample need to be further confirmed and provide preliminary data warranting future validation by direct glycogen measurement through biopsy technique.

Subcutaneous masses smaller than 5 cm can be malignant, in contrast with the international guidelines. Ultrasound (US) and magnetic resonance imaging (MRI) are useful to distinguish a potentially malignant mass from the numerous benign soft tissue (ST) lesions. Contrast-enhanced ultrasound (CEUS) was applied in ST tumors, without distinguishing the subcutaneous from the deep lesions. We evaluated CEUS and MRI accuracy in comparison to histology in differentiating malignant from nonmalignant superficial ST masses, 50% smaller than 5 cm. Sensitivity, specificity, and positive and negative predictive values (PPV, NPV) with their 95% confidence intervals (CI) were calculated. Of malignant cases, 44.4% measured ≤5 cm. At univariate analysis, no statistically significant differences emerged between benign and malignant tumors in relation with clinical characteristics, except for relationship with the deep fascia ( p = 0.048). MRI accuracy: sensitivity 52.8% (CI 37.0, 68.0), specificity 74.1% (CI 55.3, 86.8), PPV 73.1% (CI 53.9, 86.3), and NPV 54.1% (CI 38.4, 69.0). CEUS accuracy: sensitivity 75% (CI 58.9, 86.3), specificity 37% (CI 21.5, 55.8), PPV 61.4% (CI 46.6, 74.3), and NPV 52.6% (CI 31.7, 72.7). CEUS showed a sensitivity higher than MRI, whereas PPV and NPV were comparable. Also, masses measuring less than 5 cm can be malignant and referral criteria for centralization could be revised.

Background and Aims: Diabetes is a suitable model to evaluate intervention programmes aimed at chronic diseases, because of its well-defined and measurable process and outcome indicators. In this study, we aimed at investigating the effects of group based self-management education on clinical and psychological variables in type 2 diabetes., Methods and Results: Four-year randomized controlled clinical trial (ISRCTN14558376) comparing Group Care and traditional one-to-one care. Clinical and psychological variables were monitored at baseline, 2 and 4 years. Although differences between groups appear to be non-significant at univariate analysis, body weight, BMI and HbA1c, systolic and diastolic blood pressure improved in the patients followed by Group Care but not among Controls. Prescription of lipid-lowering and anti-hypertensive agents did not change among the patients on Group Care, whereas anti-hypertensives were stepped up among Controls without improving their blood pressure. Multivariable analysis suggests that blood pressure improvement among patients on Group Care was independent of BMI, duration of diabetes and antihypertensive medication, suggesting a direct effect of education, presumably by increasing adherence. The "Powerful Others" dimension of the Locus of Control worsened and fear of complications decreased among Controls., Conclusions: The results confirm that a multidisciplinary structured group educational approach improves blood pressure, presumably through better adherence to healthy lifestyle and medication, in people with type 2 diabetes., Clinical Trial Registration Number: ISRCTN14558376., Competing Interests: Declaration of Competing Interest None of the authors has any competing interests to declare., (Copyright © 2020 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background: the Italian National Prevention Plan (PNP) posed the standard to be achieved by Regions for the prevention of obesity in childhood and adolescence. The PNP also set up a monitoring system to assess the impact of implemented policies., Objectives: to develop a conceptual model to facilitate interpretation of variation in outcome indicators., Methods: after a systematic review, the DPSEEA («Driving forces», «Pressures», «State», «Exposure», «Effect», «Actions») was identified as the more appropriate framework to assess the results of preventive policies. Factors for each component of the framework were identified and indicators that allow measuring the changing of each of these factors were defined., Results: the included «driving forces» were related to the profit-led food industry, to the nutrition environment at school, and to household-level factors. Among the «pressures», parenting behaviours, food provided by school canteens, sociocultural factors, social context, physical activity (PA), opportunities at school or after-school were included. In the State, the high consumption of processed food, the large quantities of high-calorie food easy available, the consumption of carbonated and sugar-sweetened beverages, the reduced social function of mealtimes in families, the early cessation of breastfeeding, the reduction of outdoors activity, active transportation, and PA at school for children were identified. The «exposure» factors were the reduced opportunities of doing PA and the over-consumption of calories that influence the «effect», described as the prevalence of children and adolescents affected by obesity., Conclusions: through the DPSEEA, a conceptual model was set up; it allows to place in the causal chain the «actions» and the mechanisms through which these actions should impact on the «exposure» (PA and over-consumption of calories), making the rationale of process and impact indicators explicit.

Objectives: to evaluate smoking prevalence in adolescents by Italian region from the Health Behaviour Study in School-aged Children (HBSC) of 2014 and to correlate it with the presence, in the 2014-2018 Regional Prevention Plans (PRPs), of school-based smoking prevention interventions., Setting and Participants: the 2014 HBSC surveillance system provided data on 48,000 adolescents aged 11, 13, and 15 years; Ministry of Health provided data for each PRP on interventions with a tobacco control component and, among them, school-based smoking prevention interventions., Main Outcome Measures: weekly smoking prevalence; proportion of school-based smoking prevention interventions out of prevention interventions with tobacco control measures., Results: regions with the highest weekly smoking prevalence were Sardinia and Apulia for all age groups, Abruzzo for 11- and 15-year-old children, Basilicata for 15-year-old children, Bolzano for girls aged 13 years old; Liguria for females, Molise, Calabria, and Veneto for males. In the regions with the highest prevalence of smoking in 2014, in girls aged 11 and 13 years (Sardinia, Apulia, Basilicata, Liguria, Bolzano), a greater proportion of school-based smoking prevention interventions to be developed in the period 2014-2018 have been recorded., Conclusions: smoking prevalence in Italian adolescents is high, especially in 15-year-old children. Implementing policies recommended by the World Health Organization - Framework Convention on Tobacco Control (higher tobacco taxes, anti-tobacco mass media campaigns, plain tobacco package) could work synergistically with school-based interventions in order to decrease tobacco initiation among adolescents in Italy.

This research aims to study tobacco smoking and vaping among adolescents in Italy through three repeat national cross sectional surveys conducted before (in 2010, 2014) and after (2018) the 2016 introduction of the European Union - Tobacco Product Directive (EU-TPD) and its transposition into Italy, and before Juul entered the Italian market in 2019. Prevalence of smoking and vaping, access to cigarettes and electronic cigarettes in adolescents aged 13-15 years were estimated from the 2010, 2014, and 2018 Global Youth Tobacco Surveys (N = 1587; N = 1428; N = 1518, respectively) conducted in Italy. Prevalence of current smokers and/or current vapers combined, accounting for dual users, non-significantly increased from 20.7% in 2010 to 27.9% in 2018. Although current smokers stalled around 20%, current vapers substantially increased from 0% in 2010, 7.4% in 2014, to 17.5% in 2018, and current exclusive vapers recorded an almost 3-fold significantly increase from 2.9% in 2014 to 8.2% in 2018. Moreover, 42% of ever vapers used nicotine-free electronic cigarettes, and only 5% of current users were frequent vapers (≥20 days in the past month). About 65% of current smokers and 76% of current vapers easily accessed to cigarettes or electronic cigarettes in 2018. After 2 years from its implementation in 2016, the EU-TPD does not seem to have slowed down the increase in vaping among Italian adolescents before Juul entered the Italian market. Additional research is needed in order to show a clear association between EU-TPD and changes in vaping and smoking in Italy and in the EU., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Aims: Diabetic retinopathy remains asymptomatic until its late stages but remains a leading cause of vision impairment and blindness. We studied quality of life and the ability to deal with the discomfort deriving from the presence of a chronic disease in patients with type 1 diabetes and different stages of retinopathy., Methods: Multicenter collaborative observational study involving nine centers screening for retinopathy in different areas of Italy. The National Eye Institute 25-item visual functioning questionnaire and the locus of control tool were administered to 449 people with type 1 diabetes between February 2016 and March 2018. Socio-demographic and clinical data were collected., Results: On multivariable analysis, severe retinopathy is associated with worse scores for general vision, ocular pain, near vision activities, distance vision activities, driving, color vision, peripheral vision and lower values of internal control, independently of visual acuity. Women had a perception of worse general health, distance vision activities and driving, and lower internal control and trust in others. Worse scores for visual-specific social functioning, visual-specific mental health, visual-specific role difficulties, visual-specific dependency and peripheral vision were associated with higher HbA1c levels. Fatalism increased with rising HbA1c levels., Conclusions: These results confirm that a gap exists between patients' knowledge and expectations on retinopathy and providers' expertise and assumptions. To bridge this gap, patient-centered education and engaging approaches may be more effective than simple information given during consultations.

Cigarette smoking is often established during adolescence when other health-related risk behaviors tend to occur. The aim of the study was to further investigate the hypothesis that risky health behaviors tend to cluster together and to identify distinctive profiles of young adolescents based on their smoking habits. To explore the idea that smoking behavior can predict membership in a specific risk profile of adolescents, with heavy smokers being more likely to exhibit other risk behaviors, we reanalyzed the data from the 2014 Health Behaviour in School-Aged Children Italian survey of about 60,000 first- and third-grade junior high school (JHS) and second-grade high school (HS) students. A Bayesian approach was adopted for selecting the manifest variables associated with smoking; a latent class regression model was employed to identify smoking behaviors among adolescents. Finally, a health-related risk pattern associated with different types of smoking behaviors was found. Heavy smokers engaged in higher alcohol use and abuse and experienced school failure more often than their peers. Frequent smokers reported below-average academic achievement and self-rated their health as fair/poor more frequently than nonsmokers. Lifetime cannabis use and early sexual intercourse were more frequent among heavy smokers. Our findings provide elements for constructing a profile of frequent adolescent smokers and for identifying behavioral risk patterns during the transition from JHS to HS. This may provide an additional opportunity to devise interventions that could be more effective to improve smoking cessation among occasional smokers and to adequately address other risk behaviors among frequent smokers., (© 2019 Society for Risk Analysis.)

Objective: Increased risk for adverse pregnancy outcomes with advancing maternal age has been described but the strength of association remains debated, particularly in presence of confounding factors such as parity, twin pregnancy and pregnancy from assisted reproductive technologies. The aim of this study was to evaluate pregnancy outcomes in a large cohort of women aged over 40 years. The hypothesis was that advanced maternal age may be an independent risk factor for adverse pregnancy outcome., Study Design: We reviewed the clinical records of 56,211 women who delivered at Sant'Anna University Hospital, Turin, Italy, in the period between 2009 and 2015. Of these, 3798 women aged over 40 years were divided into two age groups (40 - 44 years and ≥45 years). Women of any parity, with singleton or twin pregnancies, or with assisted reproductive technology pregnancies were included. Women aged less than 40 years were considered as controls. Primary outcome measures were maternal and perinatal complications. Comparisons were performed using Chi-square test and Fisher's exact test. Univariate analysis and logistic regression analysis were performed to test the possible independent role of maternal age as a risk factor for adverse pregnancy outcome., Results: Maternal age was an independent risk factor for gestational diabetes (age 40-44 years: odds ratios (OR) 2.10, 95% CI 1.80-2.45; age ≥45 years: OR 2.83, 95% CI 1.79-4.46) and early-onset preeclampsia (age 40-44 years: OR 2.10, 95% CI 1.63-2.70; age ≥45 years: OR 3.16, 95% CI 1.68-5.94). The risk for placenta praevia was higher in the women aged 40-44 years (OR 1.87, 95% CI 1.36-2.57). Neonatal outcomes were similar among groups, except for the rate of birth weight less than 2500 g, which was higher in women aged 40-44 years (OR 1.27, 95% CI 1.12-1.42). However, older women showed an overall higher incidence of preterm birth., Conclusions: Maternal age over 40 years is an independent risk factor for adverse pregnancy outcomes, particularly for the mother. Pregnancies in women over 40 years should be considered at risk and carefully monitored with individualized care protocols.

Purpose: We examined the expression of a panel of epigenetic enzymes catalyzing histone tails post-transcriptional modifications, together with effectors of metabolic and inflammatory alterations, in type 2 diabetes., Methods: Cross-sectional, case-control study of 21 people with type 2 diabetes and 21 matched controls. Total RNA was extracted from white cells and reverse transcribed. PCR primer assays for 84 key genes encoding enzymes known to modify genomic DNA and histones were performed. Western blot was performed on lysates using primary antibodies for abnormally expressed enzymes. Hormones and cytokines were measured by multiplex kits. A Bayesian network was built to investigate the relationships between epigenetic, cytokine, and endocrine variables., Results: Co-activator-associated aRginine Methyltransferase 1 (CARM1) expression showed a five-fold higher median value, matched by higher protein levels, among patients who also had increased GIP, IL-4, IL-7, IL-13, IL-17, FGF basic, G-CSF, IFN-γ, and TNFα and decreased IP-10. In a Bayesian network approach, CARM1 expression showed a conditional dependence on diabetes, but was independent of all other variables nor appeared to influence any., Conclusions: Increased CARM1 expression in type 2 diabetes suggests that epigenetic mechanisms are altered in human diabetes. The impact of lifestyle and pharmacological treatment on regulation of this enzyme should be further investigated.

Background: Reports of the overall chronic pain prevalence and its associated demographic characteristics among adolescents vary greatly across existing studies. Using internationally comparable data, this study investigates age, sex and country-level effects in the prevalence of chronic single-site and multi-site pain among adolescents during the last six months preceding the survey., Methods: Data (n = 214,283) from the 2013/2014 Health Behaviour in School-aged Children (HBSC) study were used including nationally representative samples of 11-, 13- and 15-year-olds from general schools in 42 participating countries. Multilevel logistic regression analyses were used., Results: The overall proportion of adolescents reporting chronic weekly pain during the last six months was high (44.2%). On average, in comparison with different specific localized types of single-site pain, the prevalence of multi-site pain was more common varying from 13.2% in Armenia to 33.8% in Israel. Adolescent age and sex were strong predictors for reporting pain, but significantly different demographic patterns were found in the cross-country analyses. The most consistent findings indicate that multi-site pain was more prevalent among girls across all countries and that the prevalence increased with age., Conclusions: Internationally comparable data suggest that self-reported chronic pain among adolescents is highly prevalent, but different age and sex patterns across countries exist. Adolescents with chronic pain are not a homogenous group. Chronic pain co-occurrence and differences in chronic pain characteristics should be addressed in both clinical and public health practice for effective adolescent chronic pain management and prevention., Significance: Chronic pain co-occurrence is common during adolescence across countries, the prevalence being among girls and in older age groups. Significant cross-country variations in the chronic pain prevalence and chronic pain patterns among adolescents exist. Significant country differences emerge for specific chronic pain patterns in association with adolescent demographics., (© 2018 European Pain Federation - EFIC®.)

Background: Main aim was to describe youth smoking prevalence in Italy over the last two decades, and to provide recent trends in knowledge, attitudes towards smoking, awareness of anti-tobacco mass media campaigns, second-hand smoke (SHS) exposure and access to cigarettes., Methods: Figures from three surveillance systems, with 12 representative cross-sectional surveys (about 43 000 participants): European School Survey Project on Alcohol and Other Drugs, 15-16-year-old students, 1995-2015; Health Behaviour in School-aged Children, 11-, 13-, 15-year-old students, 2002-14 and Global Youth Tobacco Survey, 13-15-year-old students, 2010, 2014., Results: Among 11- and 13-year-old students, daily and non-daily smokers decreased by 30-50% from 2002 to 2014. Among 15-16-year-old adolescents, ever smokers significantly decreased by 10% in the period 1995-2015, whereas current and daily smokers have been stalling or even increased. Appeal of smoking increased in 2014 compared to 2010, perception of SHS as harmful, and awareness of recent anti-tobacco mass media campaigns decreased. Moreover, a significant 30% reduction in reporting retailers did not refuse to sell cigarettes to adolescents and a decrease in reporting to buy cigarettes were reported., Conclusions: Policies enforced in Italy over the last 20 years slightly reduced ever smokers, but did not decrease current and daily smokers in 15-16-year-old adolescents, and determined an impact among younger adolescents. Stricter rules on youth tobacco access reduced ease of access to cigarettes, but did not affect adolescents' tobacco use. Stronger tobacco control measures are urgently needed in order to determine a steeper decline in smoking prevalence in adolescents.

Parental and peer support seems to be a favourable determining factor in the acculturation process among young immigrants. We aimed to assess the level of perceived support among first- and second-generation adolescent immigrants and compare it to that perceived by the adolescents from the host population. Using Italian HBSC survey data collected in 2013-2014, first- and second-generation immigrants aged 11, 13 and 15 years were classified according to their ethnic background as being from Western countries, Eastern European countries, or from non-Western/non-European countries. The domains of teacher, classmate, family, and peer support was measured through multidimensional, standardised, validated scales. Analyses were run on a 47,399 valid responses (2195 from Western countries, 2424 from Eastern European countries, and 2556 from non-Western/non-European countries). Adolescent immigrants from Eastern European countries and non-Western/non-European countries reported significantly lower support than their peers from the host population in all explored domains. Girls perceived a lower level of classmate and family support compared to boys across all ethnic backgrounds. We observed two different immigration patterns: the Western pattern, from more affluent countries, and the Eastern pattern. Among the latter, second-generation immigrants showed the lowest level of support in all domains. Increasing family connections and developing peer networks should favour the acculturation process among adolescent immigrants.

Since 2009, the Department of Continuing Education at the Orthopedic and Trauma Center Hospital in Turin, Italy, has provided a training course for nurses in the management of central vascular access devices (CVADs). The course focuses on dressing and flushing procedures, as well as compliance with other CVAD guidelines. An observational study was conducted among nurses to determine the level of best practices in areas with a high prevalence of nurses trained in the management of CVADs. A correlation was observed between best practices and having attended the course, but other variables also influenced best practices.

Purpose: Detection of microaneurysms and/or microhaemorrhages near the fovea when screening for diabetic retinopathy poses a problem because referral to retinal specialists may alarm patients and unnecessarily burden ophthalmologists., Methods: Six-month prospective study of patients found to have minimal red lesions within one disc diameter of the fovea when screened for diabetic retinopathy. Two 45° digital photographs, one centred on the macula and the other nasal including the optic disc, were taken for each eye. All patients received a 6-month re-screening appointment., Results: Out of 70 patients, 41 returned for re-screening. Diabetic retinopathy had worsened in 3 who required referral but no treatment, was unchanged in 19 and was undetectable in the other 19. Haemoglobin A1c decreased from 7.76% ± 1.50% (61.3 ± 16.2 mmol/mol) to 6.93% ± 1.7% (52.3 ± 18.9 mmol/mol) in the patients in whom diabetic retinopathy worsened but did not change in the other groups. Baseline haemoglobin A1c ( p = 0.048) and systolic blood pressure ( p = 0.007) were lower in the patients in whom diabetic retinopathy improved, but a multivariate model including haemoglobin A1c, blood pressure and known disease duration could not identify any independent risk factor., Conclusion: Minimal red lesions near the fovea, though commanding early re-screening, do not require immediate referral to retinal specialists.

Purpose and Hypothesis: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated., Methods: Thirty consecutive patients of recalcitrant Achilles tendinopathy were studied with ultrasound greyscale (US), PD, CEUS and magnetic resonance imaging. Neovascularization was recorded as percentage on the whole extension of examined area. The vascularization time was recorded as venous and arterial type. Imaging data were classified both concurrently with the examination and in a secondary blinded assessment; any difference in the subjective assessment was discussed and a consensus view formed. Pain and disability were assessed by Western Ontario McMaster Universities Arthritis Index (WOMAC) and EuroQuality of life 5-dimension-5-level questionnaire and visual analogue scale (EQ-VAS). All results were analysed with suitable statistical methods., Results: 76.7% of cases were degenerated; 23.3% had also partial discontinuity of the fibres. PD detected vascularization in 54% of cases, whereas CEUS in 83% of cases: in 13 cases, PD did not detect vascularization. The vascularization time was rapid (< 20 s, arterial type) in 60% of cases. WOMAC pain mean value is 6.4 and SD 3.4; WOMAC total score mean value is 21.6 and SD 12.8. EQ-VAS mean value is 56 and SD 18.3. No statistically significant correlation emerged between vascularization and pain/disability., Conclusions: CEUS showed a greater ability to detect neovessels than PD in chronic Achilles tendinopathies. Nevertheless in 30 consecutive tendinopathies, no correlation between pain/disability and neovascularization was found: the role of multiple neovessels continue to be unclear. The possibility to discriminate arterial from venous vessels ('vascularization time') could be useful to understand the pathophysiology of tendinopathies and its healing process., Study Type: Diagnostic study., Level of Evidence: II.

Objectives: The usefulness of university admission tests to medical schools has been discussed in recent years. In the academic year 2014-15 in Italy, several students who failed the admission test appealed to the regional administrative court ('Tribunale Amministrativo Regionale'-TAR) requesting to be included, despite their test results, and all were admitted to their respective courses. The existence of this population of students generated a control group, in order to evaluate the predictive capacity of the admission test. The aim of the present work is to discuss the ability of university admission tests to predict subsequent academic success., Setting and Participants: The study involved 683 students who enrolled onto the first year of the degree course in medicine in the academic year 2014-15 at the University of Turin (Molinette and San Luigi Gonzaga colleges). The students were separated into two categories: those who passed the admission test (n1=531) and those who did not pass the admission test but won their appeal in the TAR (n2=152)., Outcomes: The validity of the admission test was analysed using specificity, sensitivity, positive and negative likelihood ratios (LH+, LH-), receiver operating characteristic (ROC) curves, area under the ROC curve (AUC), and relative (95% CI)., Results: The results showed that the admission test appeared to be a good tool for predicting the academic performances in the first year of the course (AUC=0.70, 95% CI 0.64 to 0.76). Moreover, some subject areas seemed to have a greater discriminating capacity than others. In general, students who obtained a high score in scientific questions were more likely to obtain the required standards during the first year (LH+ 1.22, 95% CI 1.14 to 1.25)., Conclusions: Based on a consistent statistical approach, our study seems to confirm the ability of the admission test to predict academic success in the first year at the school of medicine of Turin., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Background: The aim of this research is to update the trend in overweight (including obesity) prevalence among Italian adolescents, evaluating possible differences by age and gender, and analyzing their relationships with socioeconomic status, between 2002 and 2014., Methods: The present study is based on data from the Italian HBSC study at four time points (2002, 2006, 2010 and 2014), which involved 15 035 adolescents, aged 11-13-15 (7540 boys and 7495 girls)., Results: Gender and age were associated with the occurrence of overweight. In all surveys, boys had a higher prevalence of excess weight compared to girls (p < 0.001), but only among girls there was a significant increasing trend (from 11.2% in 2002 to 13.3% in 2014). From 2002 to 2014, the risk of being overweight was inversely associated with the economic level of the family, for both genders and all age groups., Conclusions: Data collected between 2002 and 2014 in Italy showed a low overall increase in prevalence of obesity and overweight and an inverse association between SES and obesity in all age groups and in both genders. These findings suggest that concerted, multi-sectorial, efforts are needed in Italy, in combination with a sound political will, focused on reducing social inequality associate.

Aim: Abnormal placentation is a common pathogenic mechanism of many placenta-mediated complications of late pregnancy, including pre-eclampsia, fetal growth restriction, stillbirth, and placental abruption. During successful placentation, the trophoblast (which is a semi-allograft) is not rejected by decidual immune cells because of maternal immune tolerance, mainly induced by human leukocyte antigen G (HLA-G). Deficient HLA-G expression seems to be associated with the development of complications of pregnancy. The aim of this study was to determine whether low soluble HLA-G (sHLA-G) levels in maternal blood at the beginning of pregnancy may be associated with subsequent placenta-mediated complications., Methods: For this retrospective case-control study, 117 cases of placenta-mediated complications of pregnancy and 234 controls with uneventful pregnancy were selected. Plasma sHLA-G levels were measured at 11-13 weeks' gestation by the enzyme-linked immunosorbent assay method in blood samples previously obtained at first-trimester prenatal screening for chromosomal fetal abnormalities., Results: Women who subsequently developed placenta-mediated complications had significantly lower sHLA-G levels at the beginning of pregnancy (median, 43.08 IU/mL) than controls (median, 49.10 IU/mL; P = 0.008). An sHLA-G level lower than 43.50 IU/mL at the end of the first trimester was associated with a twofold increased risk of developing a pregnancy complication (odds ratio, 1.82; 95% confidence interval, 1.22-2.73). The strongest association, although only moderately strong, was observed with severe pre-eclampsia (odds ratio, 2.66; 95% confidence interval, 1.08-6.56)., Conclusion: Placenta-mediated complications of pregnancy may be associated with low sHLA-G levels in the first trimester, suggesting a potential role of sHLA-G in the early stages of placentation., (© 2017 Japan Society of Obstetrics and Gynecology.)

Objectives: to consider the admission test to the degree course in Medicine and Surgery in the three campus of Piedmont Region (Northern Italy) in order to discuss the ability of this test to predict the academic outcome of the students., Design: cohort study considering all the students enrolled in the first year of medicine during the academic year 2014-2015. Their academic career is monitored during the period January 2015-February 2016., Setting and Participants: a total of 781 students is considered and divided into two groups: regular (registered after passing the admission test; n. 605) and TAR (registered after court decision and having won the case in tribunal; n. 176)., Main Outcome Measures: the study is based on three indicators of performance: A1. at least one of the required exams in the first year passed; A2. at least half of the required exams in the first year passed; A3. all the exams required in the first year passed. Statistical analyses are based on: positive predictive value and relative 95% confidence interval; odds ratio and relative 95% confidence intervals, adjusted by sex, age, high school type, and vote estimated by logistic regression models., Results: the results highlight the good prediction of the admission test that remains significant even after adjustment for the confounding factors considered., Conclusions: the major limits are the short period of observation and the restricted number of campus considered. However, this analysis confirms the importance of the admission test. In fact, students with low scores in the test could show serious disadvantages in passing the exams (in the appointed time) in the first year.

To evaluate vision related quality of life in the patients enrolled in The European Consortium for the Early Treatment of Diabetic Retinopathy, a clinical trial on prevention of diabetic retinopathy. Four-hundred-forty-nine patients, 153 women, with type 2 Diabetes and no or mild diabetic retinopathy were enrolled in a 2-year multicenter randomized controlled trial. The 25-item National Eye Institute Visual Functioning Questionnaire was used to explore 12 subscales of vision related quality of life. The patients were 62.8 ± 6.7 years old and had 11.1 ± 5.6 years known disease duration. Diabetic retinopathy was absent in 193 (43.0 %) and mild in 256 (57.0 %). Patients without diabetic retinopathy were older, had shorter diabetes duration and used less insulin and glucose-lowering agents but did not differ by gender, best corrected visual acuity or any subscale, except vision specific mental health and vision specific role difficulties. Patients with reduced retinal thickness at the ganglion cell layer (n = 36) did not differ for diabetic retinopathy but were older, had lower best corrected visual acuity and worse scores for ocular pain, color vision and peripheral vision. On multivariable analysis, worse scores for general vision remained associated with reduced retinal thickness, diabetes duration and best corrected visual acuity, and scores for visual specific mental health with diabetic retinopathy and lower best corrected visual acuity. Visual specific role difficulties were only associated with reduced best corrected visual acuity. Scores for driving decreased among females, with worsening of Hemoglobin A1c and best corrected visual acuity. Color vision depended only on reduced retinal thickness, and peripheral vision on both reduced thickness and best corrected visual acuity. The National Eye Institute Visual Functioning Questionnaire could detect subtle changes in patients' perception of visual function, despite absent/minimal diabetic retinopathy.

Purpose: Microvascular and macrovascular complications of diabetes, such as retinopathy and nephropathy, progress over time and may be associated with cognitive decline. In this article, we aim to gain further insight into the association between cognitive function and retinopathy in type 2 diabetes., Methods and Results: In this observational 8-year prospective study of 498 outpatients, demographic and clinical variables were monitored, along with retinopathy, depression, anxiety, and cognitive function. Baseline fundus photographs were available in 477 patients, 240 with no retinopathy, 110 with mild retinopathy, and 127 with moderate/more severe retinopathy. Of the first 2 groups, 279 patients were reevaluated after 8 years, of whom 181 still had no/mild retinopathy and 98 had progressed to more severe stages. On multivariate analysis, retinopathy progression was associated with being insulin-treated (p = 0.036), and worse cognitive function (p = 0.025) at baseline., Conclusions: Cognitive function may be an independent predictor of retinopathy progression.

Backgrounds and Aim: Unhealthy eating behaviours increase with age and have been associated with adverse health consequences in adulthood. We examined the influence of screen-based sedentary behaviours (SBs) on unhealthy food consumption, such as energy-dense foods and sweetened drinks, among a representative sample of nearly 60 000 adolescents and assessed the role of possible modifiers., Methods: Data come from the Italian 2009-10 Health Behaviour in School-aged Children (HBSC) survey. Data on Eating patterns, SBs, physical activity, peers network, BMI and socio-economic status (SES) were collected following the HBSC study protocol. Hierarchical logistic regression models were used., Results: Unhealthy food consumption was significantly associated with a lower intake of fruit and vegetables and with the increase of SBs in both sexes and in all ages. The risk was interestingly higher in normal weight adolescents, in those with wider relationships with peers and in low SES children., Conclusions: This study adds evidence to support the importance of investing more resources in educational initiatives both to increase parents' awareness to support adolescents on dietary choices and on time spent in screen-based behaviours, independently of their adiposity status; and to develop youth's ability to access and appropriately use media and technologies. Policy makers should also increase their attention on introducing regulatory policies on television food advertising to which youth are exposed., (© The Author 2016.

The Health Behavior in School-aged Children is a cross-national study collecting data on social and health indicators on adolescents in 43 countries. The study provides comparable data on health behaviors and health outcomes through the use of a common protocol, which have been a back bone of the study sine its initiation in 1983. Recent years, researchers within the study have noticed a questionable comparability on the widely used item on self-rated health. One of the four response categories to the item "Would you say your health is….?" showed particular variation, as the response category "Fair" varied from 20 % in Latvia and Moldova to 3-4 % in Bulgaria and Macedonia. A qualitative mini-survey of the back-translations showed that the response category "Fair" had a negative slant in 25 countries, a positive slant in 10 countries and was considered neutral in 9 countries. This finding indicates that there are what may be called semantic issues affecting comparability in international studies, since the same original word (in an English original) is interpreted differently across countries and cultures. The paper test and discuss a few possible explanations to this, however, only leaving to future studies to hold a cautious approach to international comparisons if working with the self-rated health item with four response categories.

Objective: To determine the prevalence of abnormal vaginal flora during pregnancy and associated maternal risk factors., Methods: A retrospective study was undertaken of cervicovaginal smears performed on pregnant women at a center in Turin, Italy, between 2000 and 2010. Patients were divided into three groups: women with symptoms of genital infections (G1), asymptomatic women at risk of preterm birth (G2), and asymptomatic women with no risk (G3). Logistic regression models identified variables associated with microorganisms., Results: Among 11 219 samples, 4913 (43.8%) were positive, of which 3783 (77.0%) were positive for a single microorganism. Multivariate analysis for G1 showed positive associations between multiple sexual partners and bacterial vaginosis/Ureaplasma urealyticum, and multiparity with preterm birth and U. urealyticum (P<0.05 for all). In G2, there were significant associations between multiparity with preterm birth and bacterial vaginosis/aerobic vaginitis, and North African origin and bacterial vaginosis/U. urealyticum (P<0.05 for all). In G3, there were associations between little education (<8 years) and bacterial vaginosis/U. urealyticum, multiple sexual partners and bacterial vaginosis/U. urealyticum, and bacterial vaginosis and Eastern European origin and not being married (P<0.05 for all)., Conclusion: Positive cervicovaginal smears were associated with a particular profile. Testing could be advisable for symptomatic women at any stage of pregnancy, during the first trimester for asymptomatic women at risk of preterm birth, and for some asymptomatic women., (Copyright © 2015 International Federation of Gynecology and Obstetrics.

The aim was to develop and test a brief revised version of the family affluence scale. A total of 7120 students from Denmark, Greenland, Italy, Norway, Poland, Romania, Scotland and Slovakia reported on a list of 16 potential indicators of affluence. Responses were subject to item screening and test of dimensionality. Bifactor analysis revealed a strong general factor of affluence in all countries, but with additional specific factors in all countries. The specific factors mainly reflected overlapping item content. Item screening was conducted to eliminate items with low discrimination and local dependence, reducing the number of items from sixteen to six: Number of computers, number of cars, own bedroom, holidays abroad, dishwasher, and bathroom. The six-item version was estimated with Samejima's graded response model, and tested for differential item functioning by country. Three of the six items were invariant across countries, thus anchoring the scale to a common metric across countries. The six-item scale correlated with parental reported income groups in six out of eight countries. Findings support a revision to six items in the family affluence scale.

Organ trafficking is officially banned in several countries and by the main Nephrology Societies. However, this practice is widespread and is allowed or tolerated in many countries, hence, in the absence of a universal law, the caregiver may be asked for advice, placing him/her in a difficult balance between legal aspects, moral principles and ethical judgments.In spite of the Istanbul declaration, which is a widely shared position statement against organ trafficking, the controversy on mercenary organ donation is still open and some experts argue against taking a negative stance. In the absence of clear evidence showing the clinical disadvantages of mercenary transplantation compared to chronic dialysis, self-determination of the patient (and, with several caveats, of the donor) may conflict with other ethical principles, first of all non-maleficence. The present paper was drawn up with the participation of the students, as part of the ethics course at our medical school. It discusses the situation in which the physician acts as a counselor for the patient in the way of a sort of "reverse" informed consent, in which the patient asks advice regarding a complex personal decision, and includes a peculiar application of the four principles (beneficence, non-maleficence, justice and autonomy) to the donor and recipient parties.

Background: Psychosomatic health complaints are significant indicators of adolescent well-being. The aim of this study is to describe the full set of interactions between health complaints and the presence of subjective resources, represented by the quality of relationships with parents and peers and by a positive school perception, in a population of 15-year-old adolescents. Smoking and alcohol consumption were also included in the analyses., Methods: Bayesian networks were built for males and females separately, in order to understand the interactions among all considered variables in a representative sample of 16 018 Italian adolescents participating in the Health Behaviour in School-Aged Children survey 2009-10., Results: The resulting networks show that school is the crucial node linking adolescents' well-being with parents and peer relationships, as well as with smoking and alcohol consumption., Conclusions: Adolescents' well-being, as well as the prevalence of typical risk behaviours, such as smoking and alcohol consumption, is mediated by the adolescents' academic stress. Therefore, public health interventions, to be effective, should consider addressing the school environment by making it a more inclusive environment promoting critical thinking and sense of belonging rather than just focusing on personal behaviours., (© The Author 2014.

Purpose: Although the potential consequences of immigration for adolescent problem behaviors have been addressed in many former studies, internationally comparative research is scarce. This study investigated the impact of immigration on four indicators of adolescents' emotional and behavioral problems in 10 countries, taking into account gender and immigrant generation as moderating factors., Methods: Analyses were based on data from 11-, 13-, and 15-year-old adolescents participating in the Health Behavior in School-aged Children study in Denmark, Germany, Greece, Iceland, Ireland, Italy, the Netherlands, Spain, the United States, and Wales (total N = 53,218)., Results: Both first- and second-generation immigrant adolescents reported higher levels of physical fighting and bullying and a lower life satisfaction than native adolescents, whereas second-generation immigrant adolescents reported more psychosomatic symptoms than native adolescents. Effect sizes varied considerable for the different outcomes, and similar effects were found for first- and second-generation immigrant adolescents. Differences in these indicators of emotional and behavioral problems between immigrant and native adolescents did not vary significantly with the receiving country. With two exceptions, effects of immigrant status were similar for boys and girls. Although no differences in psychosomatic symptoms were found between first-generation immigrant and native girls, first-generation immigrant boys reported less psychosomatic symptoms than native boys. Furthermore, both second-generation immigrant boys and girls reported higher levels of physical fighting than their native peers, but differences were more pronounced for boys than for girls., Conclusions: Overall, the results of this study support a risk perspective on the impact of immigration on adolescent problem behaviors., (Copyright © 2015 Society for Adolescent Health and Medicine.

Aims: Since depression, anxiety and cognitive function may be impaired in type 2 diabetes, we investigated the relationships between clinical and socioeconomic variables and these psychological dimensions., Methods: For an 8-year prospective observational study of 498 patients, 249 were not insulin-treated (NIT) and 249 were insulin-treated (IT). Demographic, socioeconomic and clinical data were monitored along with depression and anxiety (assessed by Zung questionnaire) and cognitive function by Mini Mental State Examination (MMSE)., Results: After 8 years, 131 patients remained NIT (NIT-NIT), 179 remained IT (IT-IT), 47 switched to insulin (NIT-IT), 111 were lost to follow-up and 30 were died. In all groups, HbA1c remained stable, BMI, glucose and lipid profile improved, and foot ulcers and retinopathy worsened. Mild worsening in depression and anxiety scores was observed in the IT-IT patients only. On multivariate analysis, worsening of depression was associated with female gender, disease duration and being IT-IT, and worsening of anxiety with disease duration. Decreased MMSE was associated inversely with smoking and directly with being IT-IT., Conclusions: Patients with type 2 diabetes are at relatively low risk of psycho-cognitive decline. However, being female and on long-term insulin treatment may be risk factors for psychological distress, suggesting that special attention is required for these patients.

Background: In 2011 the Agency for Public Health Education Accreditation (APHEA) was initially launched focusing on Master level (second cycle) education., Methods: Between 2012 and 2013 the Association of Schools of Public Health in the European Region, APHEA and partner schools conducted a study on the compliance of Master level programmes of public health to the accreditation criteria. A web-based survey of second cycle programmes of public health across 29 countries was conducted using the APHEA criteria. The 29 countries were categorized into four regions: Northern, Southern, Central and Eastern and Western. We applied a Chi square test to identify regional differences with regard to the compliance of the programmes to the criteria., Results: Data from 51 out of 71 schools contacted were analyzed. The compliance to the two themes of student and faculty exchange and quality management were lowest for programmes of public health throughout the EHEA. There were significant differences in the compliance between the regions with higher compliance in the Northern European region., Conclusions: Student and faculty exchange and quality management are essential for schools and programmes of public health to improve the quality of their education through expanding international knowledge and the pertinence of skills taught within European and national contexts. The results show that there are intrinsic issues with exchange and quality management as well as the role of national accreditation agencies in defining public health education for the future workforce., (© The Author 2015.

Background: Given the severity of outcomes associated with involvement in bullying and the resources spent in an effort to reduce its prevalence, it is important to investigate trends in the bullying's occurrence. The main aim of this study was to identify trends from 2002 to 2010 in prevalence of bullying and victimization among Italian adolescents., Methods: The survey reported here is part of the larger population-based cross-sectional (2002, 2006, and 2010) "Health Behaviour in School Aged Children" (HBSC) transnational study. The sample was comprised of 13,174 Italian middle and secondary school students (11- to 15-year-olds; 50.3% girls). Data were collected through a self-report questionnaire. Measures included involvement in bullying as either a perpetrator or a victim. Trends were determined using Gamma statistics., Results: Consistent and robust decreases in the prevalence of bullying between 2002 and 2010 were detected in Italy. During this time frame both frequent and occasional bullying and victimization decreased by half., Conclusions: We measured a strong decrease in involvement in bullying behavior in Italy, in particular after 2006, when the Italian government invested more systematically in the prevention effort on bullying. This is encouraging news for policymakers and practitioners working in the field of bullying prevention., (© 2015, American School Health Association.)

Background: Salivary and serum levels of interleukin-6 (IL-6) and interleukin-8 (IL-8) have previously been studied in oral cancer with conflicting results., Methods: We designed a controlled study to assess the correlation between pretreatment salivary and serum levels of IL-6 and IL-8, and all-cause survival and cancer recurrence in oral cancer patients., Results: Fifty-two oral cancer patients and 52 healthy control cases were selected. In univariate analysis, salivary IL-6 and IL-8 seemed to be more expressed in cases (p&lt;0.001 and p = 0.010, respectively). Multivariate analysis showed that higher pretreatment saliva IL-6 levels were significantly associated with better survival (hazard ratio [HR] = 8.62; 95% confidence interval [95% CI], 1.21-62.50; p = 0.031)., Conclusions: To date, this is the largest prospective controlled study that has analyzed the pretreatment salivary and serum levels of IL-6 and IL-8 in oral cancer patients, suggesting salivary IL-6 as a possible prognostic biomarker. But further validation in a larger sample is still necessary.

Background: The purpose of this study was to assess recent changes in the prevalence of overweight (including obesity) among 11-, 13- and 15-year-olds in 33 countries from 2002 to 2010., Methods: Data from 25 countries from three consecutive survey cycles (2002, 2006 and 2010) that had at least 80% response rate for self-reported height, weight and age were analysed using logistic regression analysis., Results: Overweight prevalence increased among boys in 13 countries and among girls in 12 countries; in 10 countries, predominantly in Eastern Europe, an increase was observed for both boys and girls. Stabilization in overweight rates was noted in the remaining countries; none of the countries exhibited a decrease over the 8-year period examined. In the majority of countries (20/25) there were no age differences in trends in overweight prevalence., Conclusion: In over half of the countries examined overweight prevalence did not change during 2002-2010. However, increasing overweight prevalence was noted in many Eastern European countries over this time period. Overweight prevalence remained high in several countries in Europe and North America. These patterns call for continued research in youth overweight and highlight the need to understand cross-national differences by examining macro-level indicators. Such research should feed into developing sound translations and practices to prevent and reduce overweight in youth., (© The Author 2015.

Background: Self-rated health (SRH) in adolescence is known to be associated with health outcomes in later life. We carried out a trend analysis on data coming from three waves of data collected in 32 countries (mostly European) from 2002 to 2010 coming from the Health Behaviour in School-Aged Children surveys., Methods: SRH in adolescents was assessed using a Likert scale (excellent, good, fair and poor). Responses were dichotomized into 'excellent' vs. 'rest'. Country, age and gender groups were compared based on the odds ratio of declaring excellent SRH in 2010 with respect to 2002 and 2006., Results: The trend for European adolescents indicates an improvement over the last decade, although, in the majority of countries, a higher proportion of adolescents rate their health as excellent during the period 2002-06 with respect to the second half of the decade (2006-10).Girls were found to constantly rate their health as poorer, compared to their male peers, in all countries. Age has also a very stable trend towards a decreasing rating of health with increasing age., Conclusion: Decreased rating of health in the period 2006-10 may be a signal of the socio-economic difficulties of Europe in the last part of this decade., (© The Author 2015.

Background: Life satisfaction (LS) is an indicator which is widely used for assessing the perception of a child's feeling about his life., Methods: LS is assessed in Health Behaviour in School-aged Children via the Cantril ladder with 10 steps indicating the worst and best possible life. This range of values (0-10) was dichotomized into 'low' (0-5) vs. 'high' (6-10). Countries, age groups and genders were compared based on the odds ratio (OR) of declaring a higher LS in 2010 with respect to 2002., Results: Analyzing the difference between 2002 and 2010, six countries from Western Europe show decreasing LS: Austria, Canada, Switzerland, Denmark, Finland and Greenland. In contrast, a group of Eastern European Countries, that is, Estonia, Croatia, Lithuania, Latvia, Russia and Ukraine, show a significant increase in LS. Data on gender and age differences confirm the lower rating of LS in girls and a decreasing rating with age., Conclusion: The LS scale appears to be a tool capable of discriminating the level of wellbeing of adolescent population among countries., (© The Author 2015.

Background: Health complaints are a good indicator of an individual's psychosocial health and well-being. Studies have shown that children and adolescents report health complaints which can cause significant individual burden., Methods: Using data from the international Health Behaviour in School-aged Children study, this article describes trends in multiple recurrent health complaints (MHC) in 35 countries among N = 237 136 fifteen-year-olds from 1994 to 2010. MHC was defined as the presence of two or more health complaints at least once a week. Logistic regression analysis was performed to evaluate trends across the five survey cycles for each country., Results: Lowest prevalence throughout the period 1994-2010 was 16.9% in 1998 in Austria and highest in 2006 in Israel (54.7%). Overall, six different trend patterns could be identified: No linear or quadratic trend (9 countries), linear decrease (7 countries), linear increase (5 countries), U-shape (4 countries), inverted U-shape (6 countries) and unstable (4 countries)., Conclusion: Trend analyses are valuable in providing hints about developments in populations as well as for benchmarking and evaluation purposes. The high variation in health complaints between the countries requires further investigation, but may also reflect the subjective nature of health complaints., (© The Author 2015.

Background: This article describes trends and stability over time in health complaints in adolescents from 2002 to 2010 and investigates associations between health complaints, behavioural and social contextual factors at individual level and economic factors at macro-level., Methods: Comprising N = 510 876 11-, 13- and 15-year-old children and adolescents in Europe, North America and Israel, data came from three survey cycles of the international Health Behaviour in School-aged Children (HBSC) study. Age- and gender-adjusted trends in health complaints were examined in each country by means of linear regression. By using the country as the random effects variable, we tested to what extent individual and contextual variables were associated with health complaints., Results: Significant associations are stronger for individual level determinants (e.g. being bullied, smoking) than for determinants at macro-level (e.g. GDP, Gini), as can be seen by the small effect sizes (less than 5% for different trends). Health complaints are fairly stable over time in most countries, and no clear international trend in health complaints can be observed between 2002 and 2010. The most prominent stable determinants were being female, being bullied, school pressure and smoking., Conclusion: Factors associated with health complaints are more related to the proximal environment than to distal macro-level factors. This points towards intensifying targeted interventions, (e.g. for bullying) and also targeting specific risk groups. The comparably small effect size at country-level indicates that country-level factors have an impact on health and should not be ignored., (© The Author 2015.

Introduction: Musculoskeletal Soft Tissue Tumours (STT) are frequent heterogeneous lesions. Guidelines consider a mass larger than 5 cm and deep with respect to the deep fascia potentially malignant. Contrast Enhanced Ultrasound (CEUS) can detect both vascularity and tumour neoangiogenesis. We hypothesised that perfusion patterns and vascularisation time could improve the accuracy of CEUS in discriminating malignant tumours from benign lesions., Materials and Methods: 216 STT were studied: 40% benign lesions, 60% malignant tumours, 56% in the lower limbs. Seven CEUS perfusion patterns and three types of vascularisation (arterial-venous uptake, absence of uptake) were applied. Accuracy was evaluated by comparing imaging with the histological diagnosis. Univariate and multivariate analysis, Chi-square test and t-test for independent variables were applied; significance was set at p<0.05 level, 95% computed CI., Results: CEUS pattern 6 (inhomogeneous perfusion), arterial uptake and location in the lower limb were associated with high risk of malignancy. CEUS pattern has PPV 77%, rapidity of vascularisation PPV 69%; location in the limbs is the most sensitive indicator, but NPV 52%, PPV 65%. The combination of CEUS-pattern and vascularisation has 74% PPV, 60% NPV, 70% sensitivity. No correlation with size and location in relation to the deep fascia was found., Conclusion: US with CEUS qualitative analysis could be an accurate technique to identify potentially malignant STT, for which second line imaging and biopsy are indicated in Referral Centers. Intense inhomogeneous enhancement with avascular areas and rapid vascularisation time could be useful in discriminating benign from malignant SST, overall when the lower limbs are involved., (Copyright © 2014 Elsevier Ireland Ltd.

Aims: There is conflicting evidence to support the concept that the years with diabetes preceding puberty may not contribute to the development of vascular complications. In this paper, duration-related prevalence of retinopathy was compared in patients who developed type 1 diabetes before and after pubertal age., Methods: Retrospective analysis of prospectively collected data of 1,483 patients was screened for retinopathy in 1991-2010, with diabetes onset at age ≤29, who were on insulin treatment and aged ≤60. Prepubertal age was defined as 0-12 in males and 0-11 in females., Results: A total of 647 patients had developed diabetes before and 836 after puberty. Cumulative prevalence of retinopathy was initially lower among those with prepubertal onset diabetes but rates became superimposable after 20-year duration. Patients with prepubertal onset diabetes had higher lifetime HbA1c and lower blood pressure than those who became diabetic after puberty., Conclusions/interpretation: Retinopathy is infrequent during childhood and develops later than in patients with post-pubertal onset diabetes. After 20-year duration, however, retinopathy becomes just as prevalent suggesting that, in the long term, prepubertal years do contribute to the development of retinopathy. In this series, higher blood pressure may have played a role in the earlier appearance of retinopathy in patients with diabetes onset after puberty, whereas worse metabolic control may have contributed to the late "catch-up" effect in those with prepubertal onset disease.

Background: The international increase in overweight and obesity among children and adolescents over the past three decades confirms that childhood obesity is a global 'epidemic'. The World Health Organization considers childhood obesity to be a major public health concern. Childhood obesity is associated with cardiovascular, endocrine, musculoskeletal and gastrointestinal complications, and may have psycho-social consequences. The aim of this paper is to examine overweight (including obesity) prevalence and its association with geographic area of residence, parental education and daily breakfast consumption in Italian students aged 11-15 yrs., Methods: A nationally representative sample of 11-15 year old students from 20 Italian Regions (Italian Health Behaviour in School-aged Children 2010-HBSC) was randomly selected (2,504 schools and 77,113 students). Self-reported anonymous questionnaires, prepared by the international HBSC network, were used to collect the data. BMI was calculated using self-reported weight and height and the International Obesity Task Force cut-offs. Multiple logistic regressions were performed to assess the relationship between the risk of overweight and parental education, area of residence and breakfast consumption in each age group and gender., Results: Boys were more likely to be overweight or obese than girls (28.1% vs. 18.9% at 11 yrs-old, 24.8% vs. 16.5% at 13 yrs and 25.4 vs. 11.8% at 15 yrs). The prevalence of overweight and obesity was lower among the older girls. Overweight and obesity rates increased from the North of Italy to the South in both boys and girls and in all age groups. Boys 11-15 yrs living in southern Italy had an OR=2.05 (1.77-2.38) and girls 2.04 (95% CI 1.70-2.44) for overweight (including obesity) compared with those living in the North. Parent's low educational level and no daily breakfast consumption were also associated with overweight including obesity (p<0.05)., Conclusion: The prevalence of obesity and overweight in Italian school-children 11-15 yrs old are high, in particular in the South and in boys. These findings suggest appropriate interventions are needed, at the community as well as the individual level, in particular in the southern regions. However, more research is warranted on intermediary factors to determine which interventions are likely to be most effective.

Objective: By correlating known diabetes duration with the prevalence of retinopathy, more than 10 years have been estimated to lapse between the onset and diagnosis of type 2 diabetes. Such calculations, however, assumed a linear model, included stages of retinopathy not specific to diabetes, and allowed 5 years for retinopathy to occur after the onset of diabetes. We calculated the duration of undiagnosed type 2 diabetes in outpatients screened for retinopathy in a hospital-based diabetes clinic after correcting these assumptions., Research Design and Methods: Diabetic patients (n = 12,074; 35,545 fundus examinations) were stratified into younger onset (YO; age at onset <30 years) or older onset (OO; age at onset ≥30 years), insulin treated (IT) or not IT (NIT), and with mild/more severe diabetic retinopathy (AnyDR) or moderate/more severe diabetic retinopathy (ModDR). The best-fitting equation correlating known duration among the OO-NIT group with the prevalence of ModDR was used to extrapolate time from appearance of retinopathy to diagnosis of type 2 diabetes. Time for retinopathy to develop after diabetes was calculated from the equation correlating the duration among the YO-IT group with appearance of ModDR., Results: There were 1,719 patients in the OO-NIT group with AnyDR and 685 with ModDR and 756 in the YO-IT group with AnyDR and 385 with ModDR. A linear model showed ModDR appeared 2.66 years before diagnosis among those in the OO-NIT group. A quadratic model suggested that ModDR appeared 3.29 years after diagnosis among those in the YO-IT group. The resulting estimate was 6.05 years (2.66 + 3.29) between the onset and diagnosis of diabetes, compared with 13.36 years using standard criteria., Conclusions: Using best-fitting models and stratifying by glucose-lowering treatment and severity of retinopathy substantially lowers the estimated duration of undiagnosed type 2 diabetes., (© 2014 by the American Diabetes Association.)

OBJECTIVE We prospectively evaluated the association between autoimmunity to autonomic nervous structures and autonomic neuropathy in type 1 diabetes in relation to clinical variables. RESEARCH DESIGN AND METHODS A cohort of 112 patients with type 1 diabetes was prospectively followed from adolescence (T0) to approximately 4 (T4) and 16 (T16) years later. Standard cardiovascular (CV) tests and neurological examination were performed and related to the presence of circulating antibodies (Ab) to autonomic nervous structures detected at T0 and T4. Quality of life was assessed by a diabetes-specific questionnaire. RESULTS Sixty-six patients (59% of the cohort) were reexamined at T16 (age 31.4 ± 2 years; disease duration 23.4 ± 3.7 years). Nineteen had circulating Ab to autonomic structures. Prevalence of abnormal tests and autonomic symptoms were higher in Ab-positive (68 and 26%, respectively) than Ab-negative (32 and 4%) patients (P < 0.05). Among Ab-positive patients, the relative risk (RR) of having at least one altered CV test was 5.77 (95% CI 1.56-21.33), and an altered deep breathing (DB) test (<15 bpm) was 14.65 (2.48-86.46). Previous glycemic control was the only other predictor (RR 1.06 [1.002-1.13]/mmol/mol HbA1c increase). Presence of Ab carried over a 68% probability of developing an altered CV test; absence of Ab carried a 91% probability of not having an altered DB test and an 89% probability of not having an altered Valsalva ratio. Autonomic neuropathy was independently associated with worse quality of life. CONCLUSIONS Circulating Ab to autonomic structures are associated with the development of autonomic dysfunction in young diabetic patients independent of glycemic control.

Tobacco use, alcohol abuse, overweight and obesity are risk factors for numerous diseases in Italy as elsewhere. However, children and adolescents are not usually included in official national surveys although it is at this stage of life when unhealthy habits are often established. Italian participation in HBSC and GYTS surveys allows our country to implement standardized surveillance systems providing reliable information on tobacco-related behaviors of this population. Data from three HBSC surveys (2002-2010) show that following the drop in the first half of the decade, prevalence of tobacco use stabilized in the second half. The decline was significant for younger age groups, while prevalence of regular tobacco use remained stable among 15-year-olds. Many adolescents reported being exposed to secondhand smoke, to have at least one parent who smokes, and having seen teachers and students smoking at school. Although the sale of tobacco products to minors is prohibited, the vast majority had no trouble in buying cigarettes. Data from GYTS and HBSC surveys provide a wealth of information about attitudes and behaviors of Italian adolescents with respect to smoking. Despite some progress, sizeable gaps remain in meeting standard recommendations for discouraging smoking initiation and motivating adolescent smokers to quit the habit.

Diabetic retinopathy may induce visual impairment. We evaluated vision-related quality of life in patients with visual acuity <5/10 in the better eye induced by retinopathy using the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25). The NEI VFQ-25 was self-administered to 196 patients in 3 Italian centres (A, B and C; n = 64, 61 and 71, respectively) dedicated to DR screening and treatment. Patients in the 3 centres did not differ by age, gender, occupation and diabetes duration. Multivariate analysis demonstrated that reduced visual acuity was associated with decreased scores for General Vision, Near Activities, Distance Activities, Visual-Specific Social Functioning, Mental Health, Role Difficulties and Dependency, Driving, Colour Vision and Peripheral Vision (p < 0.01, all). Treatment by photocoagulation was associated with reduced scores in General Health (-8.3; p = 0.002), General Vision (-7.2; p = 0.001), Visual-Specific Role Difficulties (-8.8; p = 0.015) and Driving (-13.7; p = 0.003). Centre affiliation was associated with different scores for General Health, Ocular pain, Distance Activities, Visual-Specific Social Functioning and Role Difficulties and Peripheral Vision. Women had higher scores for General Vision (p = 0.015), Near Activities (p = 0.005), Distance Activities (p = 0.006), Visual-Specific Social Functioning (p = 0.03), Visual-Specific Mental Health (p = 0.035) and Colour Vision (p = 0.012). Diabetic retinopathy and vision loss modify the way people perceive their own ability to function autonomously. More data should be collected to confirm this interpretation and to guide the development of more appropriate settings to improve approach and support to patients.

Aims/hypothesis: Most guidelines recommend annual screening for diabetic retinopathy (DR) but limited resources and the slow progression of DR suggest that longer recall intervals should be considered if patients have no detectable lesions. This study aimed to identify the cumulative incidence and time of development of referable DR in patients with no DR at baseline, classified by clinical characteristics., Methods: Analysis was performed of data collected prospectively over 20 years in a screening clinic based in a teaching hospital according to a consensus protocol. The cumulative incidence, time of development and relative risk of developing referable retinopathy over 6 years following a negative screening for DR were calculated in 4,320 patients, stratified according to age at onset of diabetes (<30 or ≥ 30 years), being on insulin treatment at the time of screening and known duration of diabetes (<10 or ≥ 10 years)., Results: The 6 year cumulative incidence of referable retinopathy was 10.5% (95% CI 9.4, 11.8). Retinopathy progressed within 3 years to referable severity in 6.9% (95% CI 4.3, 11.0) of patients with age at onset ≥ 30 years, who were on insulin treatment and had a known disease duration of 10 years or longer. The other patients, especially those with age at onset <30 years, on insulin and <10 years duration, progressed more slowly., Conclusions/interpretation: Screening can be repeated safely at 2 year intervals in any patient without retinopathy. Longer intervals may be practicable, provided all efforts are made to ensure adherence to standards in procedures and to trace and recall non-attenders.
