[email protected] Cancer produces a hypercoagulable state, which might lead to thrombosis, and on contrary, unprovoked venous thromboembolism might be the manifestation of an occult cancer. In this pilot case-control study, we assessed the risk of gynecological malignant diseases related to the presence of the factor V Leiden and prothrombin G20210A polymorphisms. Fifty-two women underwent an operation for gynecological malignancy and were enrolled in the study. Women who underwent an operation for gynecological nonmalignant disease in the same days of cases were considered as controls. The presence of factor V Leiden and prothrombin G20210A was assessed in case and control groups. In all, 7 out of 52 cases were carriers of the 2 polymorphisms compared with 20 out of 198 controls (odds ratio = 1.3; 95% confidence interval, 0.6-3.0). The results were also similar when the risk was considered separately for the site of cancer. As for advanced and metastatic malignancies, the odds ratios were 2.3 (95% confidence interval, 0.9-6.0) and 3.3 (95% confidence interval, 1.0-11), respectively, compared to noncancer patients. When these 2 groups were compared to nonadvanced cancer group, the odds ratios for carriers of polymorphisms were 2.7 (95%confidence interval, 0.7-11.0) and 3.9 (95%confidence interval, 0.8-18.6) for advanced cancer and metastatic malignancies, respectively. Women with factor V Leiden or prothrombin G20210A polymorphisms who developed gynecological malignancy might present with a higher stage of cancer at the time of surgery. Larger case-control studies in similar cohort of patients are needed to confirm these findings. PMID: 18591179 [PubMed - indexed for MEDLINE

Coronavirus and paramyxovirus in bats from Northwest Italy

Background: Bat-borne virus surveillance is necessary for determining inter-species transmission risks and is important due to the wide-range of bat species which may harbour potential pathogens. This study aimed to monitor coronaviruses (CoVs) and paramyxoviruses (PMVs) in bats roosting in northwest Italian regions. Our investigation was focused on CoVs and PMVs due to their proven ability to switch host and their zoonotic potential. Here we provide the phylogenetic characterization of the highly conserved polymerase gene fragments. Results: Family-wide PCR screenings were used to test 302 bats belonging to 19 different bat species. Thirty-eight animals from 12 locations were confirmed as PCR positive, with an overall detection rate of 12.6% [95% CI: 9.3–16.8]. CoV RNA was found in 36 bats belonging to eight species, while PMV RNA in three Pipistrellus spp. Phylogenetic characterization have been obtained for 15 alpha- CoVs, 5 beta-CoVs and three PMVs; moreover one P. pipistrellus resulted co-infected with both CoV and PMV. A divergent alpha-CoV clade from Myotis nattereri SpA is also described. The compact cluster of beta-CoVs from R. ferrumequinum roosts expands the current viral sequence database, specifically for this species in Europe. To our knowledge this is the first report of CoVs in Plecotus auritus and M. oxygnathus, and of PMVs in P. kuhlii. Conclusions: This study identified alpha and beta-CoVs in new bat species and in previously unsurveyed Italian regions. To our knowledge this represents the first and unique report of PMVs in Italy. The 23 new bat genetic sequences presented will expand the current molecular bat-borne virus databases. Considering the amount of novel bat-borne PMVs associated with the emergence of zoonotic infections in animals and humans in the last years, the definition of viral diversity within European bat species is needed. Performing surveillance studies within a specific geographic area can provide awareness of viral burden where bats roost in close proximity to spillover hosts, and form the basis for the appropriate control measures against potential threats for public health and optimal management of bats and their habitats
