Clostridium difficile is the leading cause of antibiotic-associated diarrhoea and a major burden to healthcare services worldwide. In recent years, C. difficile strains belonging to the BI/NAP1/027 type have become highly represented among clinical isolates. These so-called 'hypervirulent' strains are associated with outbreaks of increased disease severity, higher relapse rates and an expanded ...
Despite its relative rarity, pancreatic ductal adenocarcinoma (PDAC) accounts for a large percentage of cancer deaths. In this study, we investigated the in vitro efficacy of OSI-027, a selective inhibitor of mammalian target of rapamycin complex 1 (mTORC1) and mTORC2, to treat PDAC cell lines alone, and in combination with gemcitabine (GEM). Similarly, we tested the efficacy of these two compo...
BACKGROUND Clostridium difficile infection (CDI) has markedly risen and is associated with hypervirulent ribotype 027 outbreaks in North America and Europe since 2003. The aims of this study were to determine the prevalence of ribotype 027 among C. difficile isolates in Korea, to characterize the ribotype 027 isolates, and to determine the clinical severity of CDI in patients infected with thes...
The mammalian target of rapamycin (mTOR) plays crucial roles in proliferative and antiapoptotic signaling in lymphoid malignancies. Rapamycin analogs, which are allosteric mTOR complex 1 (mTORC1) inhibitors, are active in mantle cell lymphoma and other lymphoid neoplasms, but responses are usually partial and short-lived. In the present study we compared the effects of rapamycin with the dual m...
Since 2002, an epidemic of Clostridium difficile infections has occurred in southern Quebec, Canada. At Hôpital Maisonneuve-Rosemont, Montreal, Quebec, Canada, the incidence of C. difficile infections increased from 11/1,000 admissions (1999 to 2002) to 27/1,000 admissions (2003 to 2005). We compared the exposures and outcomes for patients infected with strains with different ribopatterns isola...
INTRODUCTION The incidence of Clostridium (C.) difficile infection (CDI) was on the rise from 2001 to 2006 in Singapore. Recent unpublished data suggests that its incidence had remained stable or decreased in most local public hospitals between 2006 and 2010. It is, however, not known if the polymerase chain reaction (PCR) ribotype 027 strains have been circulating, although reports suggest tha...
BACKGROUND The emergence of Clostridium difficile ribotype 027 raised the question of sporicidal surface disinfectants are also effective against spores of C. difficile ribotype 027. MATERIALS AND METHODS Three surface disinfectants based on magnesium monoperoxyphthalate hexahydrate (Dismozon pur), a combination of (ethylenedioxy)dimethanol, glutaral and benzyl-C12-18-alkyldimethylammonium ch...
Phosphatidylserine (PS) externalization is a marker for the nucleated cell apoptosis, and refers cellular activation rather than apoptosis in platelets. On the other hand, several similarities exist between platelet activation and apoptosis in nucleated cells. Herewith we investigated the relationship between platelet activation and platelet apoptosis. Platelets isolated from fresh blood of 22 ...
The methodology described in this article was developed to transcend the limitations of both approaches. Its goal is to use existing data to identify small areas with high levels of adolescent childbearing. The method is an active approach to identify what can be defined as “hot spots” for adolescent births, even when they are located in counties or communities where adolescent births are not c...
