Peripheral neuropathy after viral eradication with direct-acting antivirals in chronic HCV hepatitis: A prospective study.

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.

Small Subcutaneous Soft Tissue Tumors (<5 cm) Can Be Sarcomas and Contrast-Enhanced Ultrasound (CEUS) Is Useful to Identify Potentially Malignant Masses.

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.

[Development of a conceptual model for interpretation of monitoring indicators of childhood obesity prevention from the Italian National Prevention Plan]. / Sviluppo di un modello concettuale di riferimento per l'interpretazione degli indicatori di prevenzione dell'obesità infantile e nell'adolescenza nel Piano nazionale della prevenzione.

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 forces¼, «Pressures¼, «State¼, «Exposure¼, «Effect¼, «Actions¼) 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 forces¼ were related to the profit-led food industry, to the nutrition environment at school, and to household-level factors. Among the «pressures¼, 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 «exposure¼ factors were the reduced opportunities of doing PA and the over-consumption of calories that influence the «effect¼, 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 «actions¼ and the mechanisms through which these actions should impact on the «exposure¼ (PA and over-consumption of calories), making the rationale of process and impact indicators explicit.

[Smoking initiation in Italian regions, 2014, and Regional Prevention Plans]. / Iniziare a fumare nelle regioni italiane nel 2014 e Piani Regionali di Prevenzione.

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.

Self-management education may improve blood pressure in people with type 2 diabetes. A randomized controlled clinical trial.

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.

Prevalence of tobacco smoking and electronic cigarette use among adolescents in Italy: Global Youth Tobacco Surveys (GYTS), 2010, 2014, 2018.

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.

Vision-related quality of life and locus of control in type 1 diabetes: a multicenter observational study.

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 and Multiple Health Risk Behaviors: A Latent Class Regression Model to Identify a Profile of Young Adolescents.

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.

The co-activator-associated arginine methyltransferase 1 (CARM1) gene is overexpressed in type 2 diabetes.

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.

Maternal age over 40 years and pregnancy outcome: a hospital-based survey.

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.

Prevalence of self-reported chronic pain among adolescents: Evidence from 42 countries and regions.

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.

A long way to go: 20-year trends from multiple surveillance systems show a still huge use of tobacco in minors in Italy.

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.

Best Practices in the Management of Central Vascular Access Devices: An Observational Study in Areas With a High Prevalence of Trained Nurses.

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.

Detection of perimacular red dots and blots when screening for diabetic retinopathy: Refer or not refer?

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.

In Achilles tendinopathy, the neovascularization, detected by contrast-enhanced ultrasound (CEUS), is abundant but not related to symptoms.

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.

Being a Young Migrant in Italy: The Effect of Perceived Social Support in Adolescence.

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.

Is the admission test for a course in medicine a good predictor of academic performance? A case-control experience at the school of medicine of Turin.

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.

[Admission test to the degree course in Medicine and Surgery and university career: the experience in the campuses of Piedmont Region (Northern Italy)]. / Test di ammissione al corso di laurea in Medicina e chirurgia e carriera universitaria: l'esperienza nelle sedi piemontesi.

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.

Low expression of soluble human leukocyte antigen G in early gestation and subsequent placenta-mediated complications of pregnancy.

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.
