La sicurezza stradale urbana: organizzazione e realizzazione di una base dati
No full textLo studio, la redazione e l'adozione di un Piano per la Sicurezza Stradale Urbana (PSSU) costituisce, per la Pubblica Amministrazione, un impegno a perseguire nel tempo l'obiettivo della sicurezza della circolazione. Partendo da una «fotografia» della situazione dei fattori che concorrono alla sicurezza di guida in una determinata collocazione spaziale e temporale, il piano fissa obiettivi ed indica strategie per il loro raggiungimento.
Un controllo sulle strategie attuate va effettuato attraverso il monitoraggio dei parametri scelti oppure di indicatori che portino in conto un certo numero di parametri.
Lo studio preliminare per la redazione del piano ha la necessità di attingere ad informazioni che non sempre sono disponibili in modo immediato ma soprattutto non sono mai fornite in modo omogeneo. Le informazioni necessarie possono riguardare: gli
incidenti, la geometria dei luoghi, i flussi di traffico e le velocità caratteristiche di questi: le informazioni sono funzione delle metodologie di analisi dei dati. L'impegno preso con l'adozione del piano e la necessità di monitorare nel tempo gli effetti della sua applicazione sul territorio porta ad elaborare un sistema di raccolta delle informazioni di base più «comodo» per le elaborazioni relative ai successivi studi ed integrazioni.
Analizzando sinteticamente il PSSU adottato dal Comune di Benevento si illustra un sistema per la raccolta e la gestione dei dati sugli incidenti. La sua struttura è stata concepita a partire dal modello ISTAT Ctt/Inc con integrazioni dei dati: il popolamento della base dati può essere realizzato sia su moduli cartacei sia, direttamente, su un calcolatore palmare. La base dati è gestibile sulla rete telematica dell'Amministrazione ed accessibile anche dall'esterno. Essa potrà essere consultata con finalità diverse e con diversi livelli di dettaglio ed aggregazione dei dati.
In questo modo l'Amministrazione potrà avvalersi di un strumento per agevolare il lavoro di routine delle forze di Polizia Municipale che contemporaneamente verrà utilizzato dai tecnici preposti al monitoraggio dei parametri legati alla sicurezza stradale sul territorio comunale
Evaluation of menstrual blood loss (MBL) by self-perception and pictorial methods and correlation to uterine myometrial pathology
No full textPurpose: Evaluating menstrual blood loss (MBL) in primary healthcare is challenging. Our study aimed to assess MBL using two methods: self-perception and pictograms (Pictorial Blood Assessment Chart—PBAC and Menstrual Pictogram superabsorbent polymer-c version—MP) in women undergoing transvaginal ultrasound (TVS). Methods: We enrolled 221 premenopausal women with spontaneous menstruation, no hormonal therapy, and no ongoing pregnancy. They were divided into four age groups (12–20, 21–30, 31–40, and 41–55 years). Women self-reported normal (NMB) or heavy menstrual bleeding (HMB) and filled out PBAC and MP. A PBAC score ≥ 150 and MP score ≥ 80 ml indicated HMB. TVS was conducted on all patients, recording any pelvic pathologies. We compared self-perception with pictograms across the cohort, age groups, and ultrasound findings. Results: Of the cohort, 50.2% reported normal periods and 49.8% heavy periods. No significant differences were found between self-perception and pictograms in identifying NMB and HMB across all groups. However, significant differences were observed between PBAC and MP scores for NMB (56.1% vs 41.2%, p = 0.001) and HMB (43.9% vs 58.8%, p = 0.001), particularly in the 31–40 age group. Significant differences in PBAC and MP scores were noted between age groups 12–20 and 41–55, and 31–40 and 41–55. No significant differences were found between self-perception and pictograms regarding ultrasound findings like adenomyosis, fibroids, endometrial pathology, and uterine congenital malformations. Conclusion: Self-perception could be a reliable method for describing MBL across all age groups and ultrasound findings. Given the complexity and potential errors in using pictograms, clinicians should consider relying on self-perception for assessing menstrual cycle quantity
Metabolic syndrome in Italian patients with bipolar disorder
No full textObjective: This study aimed to evaluate the prevalence of metabolic syndrome (MetS) in Italian patients with bipolar disorder (BD) and to
determine the sociodemographic and clinical correlates of MetS in this patient population.
Method: Subjects with BD I and II were included. Sociodemographic and clinical characteristics, lifestyle information (alcohol and smoking
habits and rate of physical exercise) and comorbidity for cardiovascular diseases and diabetes were collected. Patients were assessed for MetS
according to both National Cholesterol Education Program Adult Treatment Panel III and International Diabetes Federation (IDF) criteria.
Results: MetS was evaluated in 99 patients out of 108 who were enrolled. MetS was present in 25.3% of the sample. Abdominal obesity was
present in 50%, hypertension in 40%, high triglycerides in 34.7%, low HDL-C levels in 32.3% and fasting hyperglycemia in 11% of the
sample. Prevalence of MetS was 30% when IDF criteria were employed. Of the investigated variables, age, duration of illness, rate of obesity
and cardiovascular disease were higher in patients with MetS. After the regression analysis, only age and obesity were associated to MetS.
Conclusions: MetS is highly prevalent in Italian patients with BD. Our 25.3% prevalence rate is consistent with the 21–22% reported in
other European studies and lower than that in U.S. studies. Elderly and obese patients with BD are at particularly high risk for MetS.

Type and Location of Adenomyosis in Women with Recurrent Pregnancy Loss: A Transvaginal Ultrasonographic Assessment
No full textThe current knowledge on adenomyosis as a risk factor for RPL is very scant. Overall 120 women were included in this retrospective observational study. They were divided in three groups each of which consisted of 40 subjects: Group 1: women with RPL who were diagnosed to have adenomyosis on transvaginal ultrasound (TVS); Group 2: patients with RPL without ultrasonographic findings of adenomyosis; Group 3: patients with ultrasound diagnosis of adenomyosis without RPL and at least one live birth pregnancy. The copresence of endometriosis was also investigated. Among women with RPL, patients with adenomyosis (Group 1) had higher number of pregnancy losses (p = 0.03) and lower age at first pregnancy loss (p = 0.03) than women without adenomyosis (Group 2). Moreover, they had more frequently primary RPL (p = 0.008). Adenomyosis of the inner myometrium was found more frequently (p = 0.04) in patients of Group 1 than in patients of Group 3 in which adenomyosis was mainly in the outer myometrium (p= 0.02). No differences were found in the severity of adenomyosis between these two groups of women. TVS findings for endometriosis were observed more frequently in women with adenomyosis without RPL (Group 3) than in the other two groups of patients. Adenomyosis can be a factor involved in RPL. Differences in adenomyosis localization are associated with different risks for RPL. Patients with RPL should be investigated for the presence of adenomyosis and also for the type and localization of the disease in the different myometrial layers
Experimental documentation of presence of purinergic receptors at human atria.
No full textOur experimental data suggest the likelihood that there is a purinergic inhibition on human atria; it appears that inhibition is mediated via P1/Ri (A-1/Ri) and P-2 receptors. Adenosine and ATP produced inhibitory effects on chronotropism and inotropism via P1/Ri (A-1/Ri) and P-2 receptors respectively

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
