Human papillomavirus typing of invasive cervical cancers in Italy
Abstract Background Human papilloma viruses (HPV) are the necessary cause of invasive cervical cancer (ICC). Of the many different types identified so far, only a few of them account for the great majority of cases worldwide, with geographical differences in their distribution. Data on the local distribution are now of interest in view of the soon-to-come introduction of HPV type-specific prophylactic vaccines. Results We have investigated HPV type distribution in samples of 48 ICC cases occurred in women living in North-East Italy in the years 1997–1999. Cases were extracted from the Venetian Tumour Registry files, as incident cases whose specimens had been processed in two Pathology Departments. Search and typing were performed by polymerase chain reaction (PCR) using GP5+/GP6+ primers, followed by direct sequencing or reverse dot blot. Three cases were PCR negative using the housekeeping primers and hence excluded. One case was negative by all HPV tests used. HPV 16 was present in 32 (72.7%) cases, as single infection in 28, in mixed infection in 4. Of the 44 positive cases, HPV 16 and HPV 18 accounted for 33 (75%), as single or mixed infections. The other high risk HPV types accounted for 11 (25%) of the remaining infections. Of the 32 HPV 16 positive cases, sequencing of the E6 gene could be performed in 25; the prototype isolate was identified in 7, and the variant T350G in 18; in 4 cases one or more additional mutations were present. Conclusions Our results suggest that HPV 16 has a very high prevalence among women with invasive cervical cancer in Italy; therefore, the use of a prophylactic vaccine for HPV types 16 and 18 could prevent up to 75% of invasive cervical cancers in Italy.</p
Clinical Study Long-Term Clinical Outcome after Treatment for High-Grade Cervical Lesions: A Retrospective Monoinstitutional Cohort Study
Background. The aim of this retrospective observational study of women treated for cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was to assess the long-term risk of residual/recurrent high-grade CIN. Materials and Methods. We evaluated 760 women treated by loop electrosurgical excision procedure (684) or conization (76) between 2000 and 2009, and followed up to June 30, 2014 (median follow-up 6.7 years, range 4-14). Visits every 6 months for the first year after treatment and yearly for up to the following 10 years included cytology, colposcopy when indicated, and HPV testing (search and typing). Results. CIN2+ or vaginal intraepithelial neoplasia grade 2 or worse (VAIN2+) was detected in 67 cases (8.8%), 39 at first follow-up and 28 after one/more negative visits. The risk of CIN2+ was higher in case of positive margins (odds ratio (OR) 8.04, 95% CI 4.31-15.0), type 3 transformation zone (OR for CIN3 27.7, 95% CI 2.07-36.9), CIN3+ excision (OR 6.02, 95% CI 1.73-20.9), and positive high-risk HPV test at first follow-up (OR for HPV16: 20.6,; OR for other hrHPV types: 18.3, 95% CI 5.9-57.0). Conclusion. Residual/recurrent high-grade CIN occurred in <9% cases, and the risk was associated with transformation zone type, lesion grade, margins status, and hrHPV test result at 6-12 months of follow-up

Confidentiality as a barrier to support seeking among physicians: The influence of psychosocial work factors in four European hospitals (The HOUPE study)
Pure enantiomers of benzoylamino-tranylcypromine: LSD1 inhibition, gene modulation in human leukemia cells and effects on clonogenic potential of murine promyelocytic blasts
The pure enantiomers of the N-(2-, 3-, and 4-(2-aminocyclopropyl)phenyl)benzamides hydrochlorides 11a-j were prepared and tested against LSD1 and MAO enzymes. The evaluation of the regioisomers 11a-j highlighted a net increase of the anti-LSD1 potency by shifting the benzamide moiety from ortho to meta and mainly to para position of tranylcypromine phenyl ring, independently from their trans or cis stereochemistry. In particular, the para-substituted 11a,b (trans) and 11g,h (cis) compounds displayed LSD1 and MAO-A inhibition at low nanomolar levels, while were less potent against MAO-B. The meta analogs 11c,d (trans) and 11i,j (cis) were in general less potent, but more efficient against MAO-A than against LSD1. In cellular assays, all the para and meta enantiomers were able to inhibit LSD1 by inducing Gfi-1b and ITGAM gene expression, with 11b,c and 11g-i giving the highest effects. Moreover, 11b and 11g,h strongly inhibited the clonogenic potential of murine promyelocytic blasts
