Mediterranean diet adherence and synergy with acute myocardial infarction and its determinants. a multicenter case-control study in Italy.

Cardiovascular diseases are the leading causes of mortality and morbidity in Western countries. The possible synergistic effect of poor adherence to a Mediterranean diet (MD) and other risk factors for acute myocardial infarction (AMI) such as hypertension, cholesterol, ever smoker, BMI> 25, diabetes, has not been deeply studied. Design Case-control study. Methods Patients with first AMI and controls from four tertiary referral Italian centers were screened for enrolment. Dietary information was collected through a questionnaire and a MD adherence score was calculated. Physical activity and smoking habits were also registered. The Synergy Index was calculated according to Rothman. Results 127 cases and 173 controls were enrolled. The analysis was conducted using a dichotomous variable for the MD score with values 7 representing good adherence. Multivariate analysis showed the following variables associated to AMI: ever smoker (OR = 2.08), diabetes (OR = 1.42), hypertension (OR = 2.08), hypercholesterolemia (OR = 2.47), BMI> 25 (OR = 1.99), while a protective effect emerged both in subjects scoring > 7 on the MD score(OR = 0.55) and in subjects resident of Southern Italy (OR = 0.38). A synergistic effect does exist between poor adherence to the MD and the following risk factors: hypertension, hypercholesterolemia, BMI >25, diabetes and being a resident in central and northern Italy. Conclusion Synergy between heart disease risk factors and MD underlines the need to enlarge the list of known modifiable cardiovascular risk factors to include and promote adherence to Mediterranean dietary habits

Il rapporto fra abitudini viziate, respirazione orale e malocclusione è fondamentale in tema di prevenzione e trattamento precoce dei disturbi della crescita cranio-facciale. Infatti così come le abitudini viziate possono interferire negativamente con la posizione dei denti e con il normale pattern di crescita scheletrica cranio-facciale, così lostruzione delle vie aeree superiori, con conseguente respirazione orale, cambia il modello di crescita craniofacciale con sviluppo di malocclusioni da moderate a severe. Questo studio trasversale, effettuato su 3.017 bambini applicando il ROMA index, vuole verificare lesistenza di una correlazione significativa tra abitudini viziate/respirazione orale e malocclusione. Dai risultati emerge che allaumentare del grado dellindice aumenta anche la prevalenza di abitudini viziate e respirazione orale, significando che questi fattori sono associati alle malocclusioni più gravi. Inoltre abbiamo riscontrato unassociazione statisticamente significativa fra abitudini viziate e overjet e openbite aumentati, ma non con il morso inverso. Dal lavoro è emerso che la respirazione orale è strettamente correlata ad overjet aumentato, overjet inverso, morso crociato, openbite e displacement. Riteniamo quindi che abitudini viziate e respirazione orale, rientrando fra i fattori di rischio di malocclusione, vadano intercettati e corretti precocemente per prevenire lo sviluppo di malocclusioni o il peggioramento di quelle preesistenti

Validation of a questionnaire for young women to assess knowledge, attitudes and behaviors towards cervical screening and vaccination against HPV in Italy

Background: Despite knowledge about HPV may be an important determinant for vaccine acceptance and uptake, only few studies have assessed HPV-related knowledge in young females. The aim of this study was to assess the reliability and validity of the questionnaire, in Italian women ≥18 years old, as a tool to examine knowledge, attitudes and behaviors towards screening and vaccination against HPV and reliable source of information. Methods: The questionnaire was administered to 30 girls in anonymous, voluntary and self -administered form with close-ended type of questions, except for the socio-demographic characteristics. It was composed in 3 sections for a total of 69 items. Participation in the study was entirely voluntary and anonymous. Descriptive analyses were performed using frequencies, percentages, and frequency table for categorical variables. Reliability analysis was tested and content validity was evaluated using Cronbach's alpha to check internal consistency and avoid misinterpretation of the results. The study was conducted in 4 Italian cities: Ferrara, Rome, Cassino and Palermo, to represent the different Italian geographical areas and knowledge, attitudes and behaviors towards screening and vaccination against HPV and reliable source of information. Data were collected in October 2010. Statistical analysis was performed with the statistical software for Windows SPSS, version 19.0. Results: The highest value of Cronbach's alpha resulted on 24 items (alpha= 0,774); the addition of other items, one at a time, decreased the value. Cronbach's alpha on all the 3 sections together resulted in a value of 0, 059. Young women generally knew that HPV can cause cervical cancer (93.3%) and genital warts (16.7%) and 76.7% of them recognized Pap-test as a screening tool. The main sources of information about HPV vaccination are represented by magazines / books (33.3%), TV (26.7%), and gynecologists (23.3%). Conclusions: This pilot study demonstrated that a short version of the questionnaire has very good reliability properties in the study and this needs to be taken into account for future studies

ASSOCIATION BETWEEN ORAL HABITS, MOUTH BREATHING AND MALOCCLUSION.

The ratio of bad habits, mouth breathing and malocclusion is an important issue in view of prevention and early treatment of disorders of the craniofacial growth. While the bad habits can interfere with the position of the teeth and the normal pattern of skeletal growth, on the other hand obstruction of the upper airway, resulting in mouth breathing, changes the pattern of craniofacial growth causing malocclusion. Our cross-sectional study, carried out on 3017 children using the ROMA index, was developed to verify if there was really a significant correlation between bad habits/mouth breathing and malocclusion. The results showed that with the increase of the degree of the index also increases the prevalence of bad habits and mouth breathing, meaning that these factors are associated with more severe malocclusions. Moreover we found a significant association of bad habits with increased overjet and openbite, while no association was found with crossbite. Additionally we found that mouth breathing is closely related to increased overjet, reduced overjet, cross bite, openbite and displacement. Therefore it is necessary to intervene early on these etiological factors of malocclusion to prevent the its development or worsening and, if it has already developed, correct it by early orthodontic treatment to promote eugnatic skeletal growth

A regulatory polymorphism in HAVCR2 modulates susceptibility to HIV-1 infection

The HAVCR2 gene encodes TIM-3, an immunoglobulin superfamily member expressed by exhausted CD8+ T cells during chronic viral infection. We investigated whether genetic variation at HAVCR2 modulates the susceptibility to HIV-1 acquisition; specifically we focused on a 3\u2032 UTR variant (rs4704846, A/G) that represents a natural selection target. We genotyped rs4704846 in three independent cohorts of HIV-1 exposed seronegative (HESN) individuals with different geographic origin (Italy and Spain) and distinct route of exposure to HIV-1 (sexual and injection drug use). Matched HIV-1 positive subjects and healthy controls were also analyzed. In all case-control cohorts the minor G allele at rs4704846 was more common in HIV-1 infected individuals than in HESN, with healthy controls showing intermediate frequency. Results from the three association analyses were combined through a random effect meta-analysis, which revealed no heterogeneity among samples (Cochrane's Q, p value = 0.89, I2 = 0) and yielded a p value of 6.8 710 124. The minor G allele at rs4704846 was found to increase HAVCR2 expression after in vitro HIV-1 infection. Thus, a positively selected polymorphism in the 3\u2032 UTR, which modulates HAVCR2 expression, is associated with the susceptibility to HIV-1 infection. These data warrant further investigation into the role of TIM-3 in the prevention and treatment of HIV-1/AIDS

Variants in the CYP7B1 gene region do not affect natural resistance to HIV-1 infection

The genetic bases of natural resistance to HIV-1 infection remain largely unknown. Recently, two genome-wide association studies suggested a role for variants within or in the vicinity of the CYP7B1 gene in modulating HIV susceptibility. CYP7B1 is an appealing candidate for this due to its contribution to antiviral immune responses. We analyzed the frequency of two previously described CYP7B1 variants (rs6996198 and rs10808739) in three independent cohorts of HIV-1 infected subjects and HIV-1 exposed seronegative individuals (HESN)
